Here's one way in XSLT 2

<?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">   <xsl:template match="@*|node()">     <xsl:copy>       <xsl:apply-templates select="@*|node()"/>     </xsl:copy>   </xsl:template>   <xsl:template match="text()">     <xsl:value-of select="translate(.,'&quot;','''')"/>   </xsl:template> </xsl:stylesheet> 

Doing it in XSLT1 is a little more problematic as it's hard to get a literal containing a single apostrophe, so you have to resort to a variable:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">   <xsl:template match="@*|node()">     <xsl:copy>       <xsl:apply-templates select="@*|node()"/>     </xsl:copy>   </xsl:template>   <xsl:variable name="apos">'</xsl:variable>   <xsl:template match="text()">     <xsl:value-of select="translate(.,'&quot;',$apos)"/>   </xsl:template> </xsl:stylesheet> 

This works for me:

1) Stop the ng server

2) Reinstall your package

npm install your-package-name

3) Run all again

ng serve

You can do it using named-entity recognition (NER). It's fairly simple and there are out-of-the-shelf tools out there to do it, such as spaCy.

NER is an NLP task where a neural network (or other method) is trained to detect certain entities, such as names, places, dates and organizations.

Example:

Sponge Bob went to South beach, he payed a ticket of $200!
I know, Michael is a good person, he goes to McDonalds, but donates to charity at St. Louis street.

Returns:

Just be aware that this is not 100%!

Here are a little snippet for you to try out:

import spacy

phrases = ['Sponge Bob went to South beach, he payed a ticket of $200!', 'I know, Michael is a good person, he goes to McDonalds, but donates to charity at St. Louis street.']
nlp = spacy.load('en')
for phrase in phrases:
   doc = nlp(phrase)
   replaced = ""
   for token in doc:
      if token in doc.ents:
         replaced+="XXXX "
      else:
         replaced+=token.text+" "

Read more here: https://spacy.io/usage/linguistic-features#named-entities

You could, instead of replacing with XXXX, replace based on the entity type, like:

if ent.label_ == "PERSON":
   replaced += "<PERSON> "

Then:

import re, random

personames = ["Jack", "Mike", "Bob", "Dylan"]

phrase = re.replace("<PERSON>", random.choice(personames), phrase)

Index-based joins

TL;DR

There are a few options, some simpler than others depending on the use case.

1. DataFrame.merge with left_index and right_index (or left_on and right_on using names indexes)
   • supports inner/left/right/full
   • can only join two at a time
   • supports column-column, index-column, index-index joins
2. DataFrame.join (join on index)
   • supports inner/left (default)/right/full
   • can join multiple DataFrames at a time
   • supports index-index joins
3. pd.concat (joins on index)
   • supports inner/full (default)
   • can join multiple DataFrames at a time
   • supports index-index joins

Index to index joins

Setup & Basics

import pandas as pd
import numpy as np

np.random.seed([3, 14])
left = pd.DataFrame(data={'value': np.random.randn(4)}, 
                    index=['A', 'B', 'C', 'D'])    
right = pd.DataFrame(data={'value': np.random.randn(4)},  
                     index=['B', 'D', 'E', 'F'])
left.index.name = right.index.name = 'idxkey'

left
           value
idxkey          
A      -0.602923
B      -0.402655
C       0.302329
D      -0.524349

right
 
           value
idxkey          
B       0.543843
D       0.013135
E      -0.326498
F       1.385076

Typically, an inner join on index would look like this:

left.merge(right, left_index=True, right_index=True)

         value_x   value_y
idxkey                    
B      -0.402655  0.543843
D      -0.524349  0.013135

Other joins follow similar syntax.

Notable Alternatives

1. DataFrame.join defaults to joins on the index. DataFrame.join does a LEFT OUTER JOIN by default, so how='inner' is necessary here.

    left.join(right, how='inner', lsuffix='_x', rsuffix='_y')
   
             value_x   value_y
    idxkey                    
    B      -0.402655  0.543843
    D      -0.524349  0.013135
   

   Note that I needed to specify the lsuffix and rsuffix arguments since join would otherwise error out:

    left.join(right)
    ValueError: columns overlap but no suffix specified: Index(['value'], dtype='object')
   

   Since the column names are the same. This would not be a problem if they were differently named.

    left.rename(columns={'value':'leftvalue'}).join(right, how='inner')
   
            leftvalue     value
    idxkey                     
    B       -0.402655  0.543843
    D       -0.524349  0.013135
   

2. pd.concat joins on the index and can join two or more DataFrames at once. It does a full outer join by default, so how='inner' is required here..

    pd.concat([left, right], axis=1, sort=False, join='inner')
   
               value     value
    idxkey                    
    B      -0.402655  0.543843
    D      -0.524349  0.013135
   

   For more information on concat, see this post.

Index to Column joins

To perform an inner join using index of left, column of right, you will use DataFrame.merge a combination of left_index=True and right_on=....

right2 = right.reset_index().rename({'idxkey' : 'colkey'}, axis=1)
right2
 
  colkey     value
0      B  0.543843
1      D  0.013135
2      E -0.326498
3      F  1.385076

left.merge(right2, left_index=True, right_on='colkey')

    value_x colkey   value_y
0 -0.402655      B  0.543843
1 -0.524349      D  0.013135

Other joins follow a similar structure. Note that only merge can perform index to column joins. You can join on multiple columns, provided the number of index levels on the left equals the number of columns on the right.

join and concat are not capable of mixed merges. You will need to set the index as a pre-step using DataFrame.set_index.

Effectively using Named Index [pandas >= 0.23]

If your index is named, then from pandas >= 0.23, DataFrame.merge allows you to specify the index name to on (or left_on and right_on as necessary).

left.merge(right, on='idxkey')

         value_x   value_y
idxkey                    
B      -0.402655  0.543843
D      -0.524349  0.013135

For the previous example of merging with the index of left, column of right, you can use left_on with the index name of left:

left.merge(right2, left_on='idxkey', right_on='colkey')

    value_x colkey   value_y
0 -0.402655      B  0.543843
1 -0.524349      D  0.013135

tl;dr:

concat and append currently sort the non-concatenation index (e.g. columns if you're adding rows) if the columns don't match. In pandas 0.23 this started generating a warning; pass the parameter sort=True to silence it. In the future the default will change to not sort, so it's best to specify either sort=True or False now, or better yet ensure that your non-concatenation indices match.

The warning is new in pandas 0.23.0:

In a future version of pandas pandas.concat() and DataFrame.append() will no longer sort the non-concatenation axis when it is not already aligned. The current behavior is the same as the previous (sorting), but now a warning is issued when sort is not specified and the non-concatenation axis is not aligned, link.

More information from linked very old github issue, comment by smcinerney :

When concat'ing DataFrames, the column names get alphanumerically sorted if there are any differences between them. If they're identical across DataFrames, they don't get sorted.

This sort is undocumented and unwanted. Certainly the default behavior should be no-sort.

After some time the parameter sort was implemented in pandas.concat and DataFrame.append:

sort : boolean, default None

Sort non-concatenation axis if it is not already aligned when join is 'outer'. The current default of sorting is deprecated and will change to not-sorting in a future version of pandas.

Explicitly pass sort=True to silence the warning and sort. Explicitly pass sort=False to silence the warning and not sort.

This has no effect when join='inner', which already preserves the order of the non-concatenation axis.

So if both DataFrames have the same columns in the same order, there is no warning and no sorting:

df1 = pd.DataFrame({"a": [1, 2], "b": [0, 8]}, columns=['a', 'b'])
df2 = pd.DataFrame({"a": [4, 5], "b": [7, 3]}, columns=['a', 'b'])

print (pd.concat([df1, df2]))
   a  b
0  1  0
1  2  8
0  4  7
1  5  3

df1 = pd.DataFrame({"a": [1, 2], "b": [0, 8]}, columns=['b', 'a'])
df2 = pd.DataFrame({"a": [4, 5], "b": [7, 3]}, columns=['b', 'a'])

print (pd.concat([df1, df2]))
   b  a
0  0  1
1  8  2
0  7  4
1  3  5

But if the DataFrames have different columns, or the same columns in a different order, pandas returns a warning if no parameter sort is explicitly set (sort=None is the default value):

df1 = pd.DataFrame({"a": [1, 2], "b": [0, 8]}, columns=['b', 'a'])
df2 = pd.DataFrame({"a": [4, 5], "b": [7, 3]}, columns=['a', 'b'])

print (pd.concat([df1, df2]))

FutureWarning: Sorting because non-concatenation axis is not aligned.

   a  b
0  1  0
1  2  8
0  4  7
1  5  3

print (pd.concat([df1, df2], sort=True))
   a  b
0  1  0
1  2  8
0  4  7
1  5  3

print (pd.concat([df1, df2], sort=False))
   b  a
0  0  1
1  8  2
0  7  4
1  3  5

If the DataFrames have different columns, but the first columns are aligned - they will be correctly assigned to each other (columns a and b from df1 with a and b from df2 in the example below) because they exist in both. For other columns that exist in one but not both DataFrames, missing values are created.

Lastly, if you pass sort=True, columns are sorted alphanumerically. If sort=False and the second DafaFrame has columns that are not in the first, they are appended to the end with no sorting:

df1 = pd.DataFrame({"a": [1, 2], "b": [0, 8], 'e':[5, 0]}, 
                    columns=['b', 'a','e'])
df2 = pd.DataFrame({"a": [4, 5], "b": [7, 3], 'c':[2, 8], 'd':[7, 0]}, 
                    columns=['c','b','a','d'])

print (pd.concat([df1, df2]))

D:project/contactlist npm install then D:project/contactlist ng new client

D:project/contactlist/client ng serve

this worked for me for some reason i had to delete the client folder and start npm install from the contactlist folder. i tried every thing even clearing the cache and finally this worked.

for angular 6 and above

The working solution for me was

npm install

ng update

and finally

npm update

You can just inject the DOCUMENT token into the constructor and use the same functions on it

import { Inject }  from '@angular/core';
import { DOCUMENT } from '@angular/common'; 

@Component({...})
export class AppCmp {
   constructor(@Inject(DOCUMENT) document) {
      document.getElementById('el');
   }
}

Or if the element you want to get is in that component, you can use template references.

I was facing the same problem, then in my app.module.ts I updated the file this way,

import { HttpModule } from '@angular/http';
import { HttpClientModule } from '@angular/common/http';

and in the same file (app.module.ts) in my @NgModule imports[]array I wrote this way,

HttpModule,
HttpClientModule

for i in range(100):
try:
  #Your code here
  break
except:
  continue

This one worked for me.

The Visual Studio Build tools are a different download than the IDE. They appear to be a pretty small subset, and they're called Build Tools for Visual Studio 2019 (download).

You can use the GUI to do the installation, or you can script the installation of msbuild:

vs_buildtools.exe --add Microsoft.VisualStudio.Workload.MSBuildTools --quiet

Microsoft.VisualStudio.Workload.MSBuildTools is a "wrapper" ID for the three subcomponents you need:

• Microsoft.Component.MSBuild
• Microsoft.VisualStudio.Component.CoreBuildTools
• Microsoft.VisualStudio.Component.Roslyn.Compiler

You can find documentation about the other available CLI switches here.

The build tools installation is much quicker than the full IDE. In my test, it took 5-10 seconds. With --quiet there is no progress indicator other than a brief cursor change. If the installation was successful, you should be able to see the build tools in %programfiles(x86)%\Microsoft Visual Studio\2019\BuildTools\MSBuild\Current\Bin.

If you don't see them there, try running without --quiet to see any error messages that may occur during installation.

According to the documentation on here http://angularjs.blogspot.co.uk/2017/03/angular-400-now-available.html you 'should' just be able to run...

npm install @angular/{common,compiler,compiler-cli,core,forms,http,platform-browser,platform-browser-dynamic,platform-server,router,animations}@latest typescript@latest --save

I tried it and got a couple of errors due to my zone.js and ngrx/store libraries being older versions.

Updating those to the latest versions npm install zone.js@latest --save and npm install @ngrx/store@latest -save, then running the angular install again worked for me.

All you need is:

guard let url = URL(string: "http://www.google.com") else {
  return //be safe
}

if #available(iOS 10.0, *) {
    UIApplication.shared.open(url, options: [:], completionHandler: nil)
} else {
    UIApplication.shared.openURL(url)
}

I will give simple steps to add favicon :-)

• Create your logo and save as logo.png

• Change logo.png to favicon.ico

  Note : when you save it is favicon.ico make sure it's not favicon.ico.png

• It might take some time to update

  change icon size in manifest.json if you can't wait

According to the documentation, 'RefererNotAllowedMapError' means

The current URL loading the Google Maps JavaScript API has not been added to the list of allowed referrers. Please check the referrer settings of your API key on the Google Developers Console.

I have the Google Maps Embed API set up for my own personal/work use and thus far have not specified any HTTP referrers. I register no errors. Your settings must be making Google think the URL you're visiting is not registered or allowed.

Simpal an easy In my case it solved by as below

Make sure your pakage name in mainifests file same as your gradle's applicationId.

Adding answer as this was the top hit when searching for "drop multiple columns in r":

The general version of the single column removal, e.g df$column1 <- NULL, is to use list(NULL):

df[ ,c('column1', 'column2')] <- list(NULL)

This also works for position index as well:

df[ ,c(1,2)] <- list(NULL)

This is a more general drop and as some comments have mentioned, removing by indices isn't recommended. Plus the familiar negative subset (used in other answers) doesn't work for columns given as strings:

> iris[ ,-c("Species")]
Error in -"Species" : invalid argument to unary operator

You can also try using apply with get method of dictionary, seems to be little faster than replace:

data['sex'] = data['sex'].apply({1:'Male', 0:'Female'}.get)

Testing with timeit:

%%timeit
data['sex'].replace([0,1],['Female','Male'],inplace=True)

Result:

The slowest run took 5.83 times longer than the fastest. This could mean that an intermediate result is being cached.
1000 loops, best of 3: 510 µs per loop

Using apply:

%%timeit
data['sex'] = data['sex'].apply({1:'Male', 0:'Female'}.get)

Result:

The slowest run took 5.92 times longer than the fastest. This could mean that an intermediate result is being cached.
1000 loops, best of 3: 331 µs per loop

Note: apply with dictionary should be used if all the possible values of the columns in the dataframe are defined in the dictionary else, it will have empty for those not defined in dictionary.

This answer is for Swift 4, and is pretty straight forward with the ability to let backspace through.

func textField(_ textField: UITextField, 
               shouldChangeCharactersIn range: NSRange, 
               replacementString string: String) -> Bool {
    return textField.text!.count < 10 || string == ""
}

In order to use source map, you should change devtool option value from true to the value which available in this list, for instance source-map

devtool: 'source-map'

devtool: 'source-map' - A SourceMap is emitted.

You could use cut

 df$valueBin <- cut(df$value, c(-Inf, 250, 500, 1000, 2000, Inf), 
    labels=c('<=250', '250-500', '500-1,000', '1,000-2,000', '>2,000'))

data

 set.seed(24)
 df <- data.frame(value= sample(0:2500, 100, replace=TRUE))

As of now (Jan 2017 / Angular > 2.0) you can use the following:

changeBackground(): any {
    return { 'background-color': this.color };
}

and

<div class="circle" [ngStyle]="changeBackground()">
    <!-- <content></content> --> <!-- content is now deprecated -->
    <ng-content><ng-content> <!-- Use ng-content instead -->
</div>

The shortest way is probably like this:

<div class="circle" [ngStyle]="{ 'background-color': color }">
    <!-- <content></content> --> <!-- content is now deprecated -->
    <ng-content><ng-content> <!-- Use ng-content instead -->
</div>

If you are only looking to replace all occurrences of "< " (with space) with "<" (no space), then you can do an lapply over the data frame, with a gsub for replacement:

> data <- data.frame(lapply(data, function(x) {
+                  gsub("< ", "<", x)
+              }))
> data
  name var1 var2
1    a   <2   <3
2    a   <2   <3
3    a   <2   <3
4    b   <2   <3
5    b   <2   <3
6    b   <2   <3
7    c   <2   <3
8    c   <2   <3
9    c   <2   <3

HTML

    ...
    <input name="GoogleMapsAPIKey" type="text" class="form-control" placeholder="Enter Google maps API key" />
    ....
    <span class="text-danger" id="GoogleMapsAPIKey-errorMsg"></span>'
    ...
    <button type="submit" class="btn btn-primary">Save</button>
</form>

Javascript

$(function () {
    $("#GoogleMapsApiKeyForm").validate({
      rules: {
          GoogleMapsAPIKey: {
              required: true
          }
        },
        messages: {
            GoogleMapsAPIKey: 'Google maps api key is required',
        },
        errorPlacement: function (error, element) {
            if (element.attr("name") == "GoogleMapsAPIKey")
                $("#GoogleMapsAPIKey-errorMsg").html(error);
        },
        submitHandler: function (form) {
           // form.submit(); //if you need Ajax submit follow for rest of code below
        }
    });

    //If you want to use ajax
    $("#GoogleMapsApiKeyForm").submit(function (e) {
        e.preventDefault();
        if (!$("#GoogleMapsApiKeyForm").valid())
            return;

       //Put your ajax call here
    });
});

This is similar to Emilie's answer however since you asked specifically how to convert the NSRange to Range<String.Index> you would do something like this:

func textField(textField: UITextField, shouldChangeCharactersInRange range: NSRange, replacementString string: String) -> Bool {

     let start = advance(textField.text.startIndex, range.location) 
     let end = advance(start, range.length) 
     let swiftRange = Range<String.Index>(start: start, end: end) 
     ...

}

The new Android Design Support Library adds TabLayout, providing a tab implementation that matches the material design guidelines for tabs. A complete walkthrough of how to implement Tabs and ViewPager can be found in this video

Now deprecated: The PagerTabStrip is part of the support library (and has been for some time) and serves as a direct replacement. If you prefer the newer Google Play style tabs, you can use the PagerSlidingTabStrip library or modify either of the Google provided examples SlidingTabsBasic or SlidingTabsColors as explained in this Dev Bytes video.

What is your opinion to use express-generator it will generate skeleton project to start with, without deprecated messages appeared in your log

run this command

npm install express-generator -g

Now, create new Express.js starter application by type this command in your Node projects folder.

express node-express-app

That command tell express to generate new Node.js application with the name node-express-app.

then Go to the newly created project directory, install npm packages and start the app using the command

cd node-express-app && npm install && npm start

My two cents for Xcode 8:

a) A custom flag using the -D prefix works fine, but...

b) Simpler use:

In Xcode 8 there is a new section: "Active Compilation Conditions", already with two rows, for debug and release.

Simply add your define WITHOUT -D.

This is what you really want.

<Button
       android:id="@+id/settings"
       android:layout_width="190dp"
       android:layout_height="wrap_content"
       android:layout_gravity="center_horizontal"
       android:background="@color/colorAccent"
       android:drawableStart="@drawable/ic_settings_black_24dp"
       android:paddingStart="40dp"
       android:paddingEnd="40dp"
       android:text="settings"
       android:textColor="#FFF" />

Your regex should work 'as-is'. Assuming that it is doing what you want it to.

This means match wordA followed by 0 or more spaces followed by wordB, but do not match if followed by wordc. Note the single space between ?! and wordc which means that wordA wordB wordc will not match, but wordA wordB wordc will.

Here are some example matches and the associated replacement output:

Note that all matches are replaced no matter how many spaces. There are a couple of other points: -

• (?! wordc) is a negative lookahead, so you wont match lines wordA wordB wordc which is assume is intended (and is why the last line is not matched). Currently you are relying on the space after ?! to match the whitespace. You may want to be more precise and use (?!\swordc). If you want to match against more than one space before wordc you can use (?!\s*wordc) for 0 or more spaces or (?!\s*+wordc) for 1 or more spaces depending on what your intention is. Of course, if you do want to match lines with wordc after wordB then you shouldn't use a negative lookahead.

• * will match 0 or more spaces so it will match wordAwordB. You may want to consider + if you want at least one space.

• (\s*) - the brackets indicate a capturing group. Are you capturing the whitespace to a group for a reason? If not you could just remove the brackets, i.e. just use \s.

Update based on comment

Hello the problem is not the expression but the HTML out put   that are not considered as whitespace. it's a Joomla website.

Preserving your original regex you can use:

wordA((?:\s| )*)wordB(?!(?:\s| )wordc)

The only difference is that not the regex matches whitespace OR  . I replaced wordc with \swordc since that is more explicit. Note as I have already pointed out that the negative lookahead ?! will not match when wordB is followed by a single whitespace and wordc. If you want to match multiple whitespaces then see my comments above. I also preserved the capture group around the whitespace, if you don't want this then remove the brackets as already described above.

Example matches:

The I attribute only exists on matrix objects, not ndarrays. You can use numpy.linalg.inv to invert arrays:

inverse = numpy.linalg.inv(x)

Note that the way you're generating matrices, not all of them will be invertible. You will either need to change the way you're generating matrices, or skip the ones that aren't invertible.

try:
    inverse = numpy.linalg.inv(x)
except numpy.linalg.LinAlgError:
    # Not invertible. Skip this one.
    pass
else:
    # continue with what you were doing

Also, if you want to go through all 3x3 matrices with elements drawn from [0, 10), you want the following:

for comb in itertools.product(range(10), repeat=9):

rather than combinations_with_replacement, or you'll skip matrices like

numpy.array([[0, 1, 0],
             [0, 0, 0],
             [0, 0, 0]])

dplyr version 0.3 added a new rename() function that works just like plyr::rename().

df <- rename(df, new_name = old_name)

This works for me:

android {
   packagingOptions {
       exclude 'LICENSE.txt'
   }
}

There's no need for jquery, its a late anwser but I figured since is the top voted one, I should point out this.

The URL is missing the protocol information. PHP thinks it is a filesystem path and tries to access the file at the specified location. However, the location doesn't actually exist in your filesystem and an error is thrown.

You'll need to add http or https at the beginning of the URL you're trying to get the contents from:

$json = json_decode(file_get_contents('http://...'));

As for the following error:

Unable to find the wrapper - did you forget to enable it when you configured PHP?

Your Apache installation probably wasn't compiled with SSL support. You could manually try to install OpenSSL and use it, or use cURL. I personally prefer cURL over file_get_contents(). Here's a function you can use:

function curl_get_contents($url)
{
  $ch = curl_init($url);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
  curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
  curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
  curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
  $data = curl_exec($ch);
  curl_close($ch);
  return $data;
}

Usage:

$url = 'https://...';
$json = json_decode(curl_get_contents($url));

You can find a good explanation of why it was replaced by reading A name for the null pointer: nullptr, to quote the paper:

This problem falls into the following categories:

• Improve support for library building, by providing a way for users to write less ambiguous code, so that over time library writers will not need to worry about overloading on integral and pointer types.

• Improve support for generic programming, by making it easier to express both integer 0 and nullptr unambiguously.

• Make C++ easier to teach and learn.

Replace (.*")\d+(")

Where x is your "value inside scopes".

This is my code to add paddingRight and paddingBottom to a View to dodge the Navigation Bar. I combined some of the answers here and made a special clause for landscape orientation together with isInMultiWindowMode. The key is to read navigation_bar_height, but also check config_showNavigationBar to make sure we should actually use the height.

None of the previous solutions worked for me. As of Android 7.0 you have to take Multi Window Mode into consideration. This breaks the implementations comparing display.realSize with display.size since realSize gives you the dimensions of the whole screen (both split windows) and size only gives you the dimensions of your App window. Setting padding to this difference will leave your whole view being padding.

/** Adds padding to a view to dodge the navigation bar.

    Unfortunately something like this needs to be done since there
    are no attr or dimens value available to get the navigation bar
    height (as of December 2016). */
public static void addNavigationBarPadding(Activity context, View v) {
    Resources resources = context.getResources();
    if (hasNavigationBar(resources)) {
        int orientation = resources.getConfiguration().orientation;
        int size = getNavigationBarSize(resources);
        switch (orientation) {
        case Configuration.ORIENTATION_LANDSCAPE:
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N &&
                context.isInMultiWindowMode()) { break; }
            v.setPadding(v.getPaddingLeft(), v.getPaddingTop(),
                         v.getPaddingRight() + size, v.getPaddingBottom());
            break;
        case Configuration.ORIENTATION_PORTRAIT:
            v.setPadding(v.getPaddingLeft(), v.getPaddingTop(),
                         v.getPaddingRight(), v.getPaddingBottom() + size);
            break;
        }
    }
}

private static int getNavigationBarSize(Resources resources) {
    int resourceId = resources.getIdentifier("navigation_bar_height",
                                             "dimen", "android");
    return resourceId > 0 ? resources.getDimensionPixelSize(resourceId) : 0;
}

private static boolean hasNavigationBar(Resources resources) {
    int hasNavBarId = resources.getIdentifier("config_showNavigationBar",
                                              "bool", "android");
    return hasNavBarId > 0 && resources.getBoolean(hasNavBarId);

If the replacement character can be '?' instead of a space, then I'd suggest result = text.encode('ascii', 'replace').decode():

"""Test the performance of different non-ASCII replacement methods."""


import re
from timeit import timeit


# 10_000 is typical in the project that I'm working on and most of the text
# is going to be non-ASCII.
text = 'Æ' * 10_000


print(timeit(
    """
result = ''.join([c if ord(c) < 128 else '?' for c in text])
    """,
    number=1000,
    globals=globals(),
))

print(timeit(
    """
result = text.encode('ascii', 'replace').decode()
    """,
    number=1000,
    globals=globals(),
))

Results:

For external keystores, prefix with "file:"

Probably your new domain contain / ? If so, try using separator other than / in sed, e.g. #, , etc.

find ./ -type f -exec sed -i 's#192.168.20.1#new.domain.com#' {} \;

It would also be good to enclose s/// in single quote rather than double quote to avoid variable substitution or any other unexpected behaviour

To change the popover width you may override the template:

$('#name').popover({
    template: '<div class="popover" role="tooltip" style="width: 500px;"><div class="arrow"></div><h3 class="popover-title"></h3><div class="popover-content"><div class="data-content"></div></div></div>'
})

You can do:

x[, 1:2][is.na(x[, 1:2])] <- 0

or better (IMHO), use the variable names:

x[c("a", "b")][is.na(x[c("a", "b")])] <- 0

In both cases, 1:2 or c("a", "b") can be replaced by a pre-defined vector.

Create a function that takes a UILabel instance. and returns CGSize

I have had a similar issue recently and realised that it's not due to background-size:cover but background-attachment:fixed.

I solved the issue by using a media query for iPhone and setting background-attachment property to scroll.

For my case:

.cover {
    background-size: cover;
    background-attachment: fixed;
    background-position: center center;

    @media (max-width: @iphone-screen) {
        background-attachment: scroll;
    }
}

Edit: The code block is in LESS and assumes a pre-defined variable for @iphone-screen. Thanks for the notice @stephband.

In my case to get my debug build - I have to turn off Instant Run option :

File ? Settings ? Build, Execution, Deployment ? Instant Run and uncheck Enable Instant Run.

Then after run project - I found my build into Application\app\build\outputs\appDebug\apk directory

I agree with @kent that this is well suited for grep -o. If you need to extract a group within a pattern, you can do it with a 2nd grep.

# To extract \1 from /xx([0-9]+)yy/
$ echo "aa678bb xx123yy xx4yy aa42 aa9bb" | grep -Eo 'xx[0-9]+yy' | grep -Eo '[0-9]+'
123
4

# To extract \1 from /a([0-9]+)b/
$ echo "aa678bb xx123yy xx4yy aa42 aa9bb" | grep -Eo 'a[0-9]+b' | grep -Eo '[0-9]+'
678
9

I generally cringe when I see 2 calls to grep/sed/awk piped together, but it's not always wrong. While we should exercise our skills of doing things efficiently, "A foolish consistency is the hobgoblin of little minds", and "Real artists ship".

Someone linked me this: What is the best way to move an element that's on the top to the bottom in Responsive design.

The solution in that worked perfectly. Though it doesn’t support old IE, that doesn’t matter for me, since I’m using responsive design for mobile. And it works for most mobile browsers.

Basically, I had this:

@media (max-width: 30em) {
  .container {
    display: -webkit-box;
    display: -moz-box;
    display: -ms-flexbox;
    display: -webkit-flex;
    display: flex;
    -webkit-box-orient: vertical;
    -moz-box-orient: vertical;
    -webkit-flex-direction: column;
    -ms-flex-direction: column;
    flex-direction: column;
    /* optional */
    -webkit-box-align: start;
    -moz-box-align: start;
    -ms-flex-align: start;
    -webkit-align-items: flex-start;
    align-items: flex-start;
  }

  .container .first_div {
    -webkit-box-ordinal-group: 2;
    -moz-box-ordinal-group: 2;
    -ms-flex-order: 2;
    -webkit-order: 2;
    order: 2;
  }

  .container .second_div {
    -webkit-box-ordinal-group: 1;
    -moz-box-ordinal-group: 1;
    -ms-flex-order: 1;
    -webkit-order: 1;
    order: 1;
  }
}

This worked better than floats for me, because I needed them stacked on top of each other and I had about five different divs that I had to swap around the position of.

You can also do it like this:

var tt="88,9827";
tt=tt.replace(",", ".");
alert(tt);

working fiddle example

I needed the best x results of points per team.

Ranking does not solves this problem when there are results with equal points. So I need a recordnumber

I made a VBA function in Access to create a recordnumber that resets on ID change.

You have to query this query with where recordnumber <= x to get the points per team.

NB Access changes the record-number

1. when you query the query filtered on record number
2. when you filter out some results
3. when you change the sort order

That is not what I thought that would happen.

Solved this by using a temporary table and saving the recordnumbers and keys or an extra field in the table.

SELECT ID, Points, RecordNumberOffId([ID}) AS Recordnumber
FROM Team ORDER BY ID ASC, Points DESC;

It uses 3 module level variables to remember between calls

Dim PreviousID As Long
Dim PreviousRecordNumber As Long
Dim TimeLastID As Date

Public Function RecordNumberOffID(ID As Long) As Long 
'ID is sortgroup identity
'Reset if last call longer dan nn seconds in the past
If Time() - TimeLastID > 0.0003 Then '0,000277778 = 1 second
    PreviousID = 0
    PreviousRecordNumber = 0
End If
If ID <> PreviousID Then
    PreviousRecordNumber = 0
    PreviousID = ID
End If
PreviousRecordNumber = PreviousRecordNumber + 1
RecordNumberOffID = PreviousRecordNumber
TimeLastID = Time()
End Function

Probably way too late but this is another option:

 $('body').popover({
    selector: '[rel=popover]',
    trigger: 'hover',
    html: true,
    content: function () {
        return $(this).parents('.row').first().find('.metaContainer').html();
    }
});

The following functions are available to obtain the current date and/or time in PostgreSQL:

CURRENT_TIME

CURRENT_DATE

CURRENT_TIMESTAMP

Example

SELECT CURRENT_TIME;
08:05:18.864750+05:30

SELECT CURRENT_DATE;
2020-05-14

SELECT CURRENT_TIMESTAMP;
2020-05-14 08:04:51.290498+05:30

You can also use jQuery's delay() method instead of setTimeout(). It'll give you much more readable code. Here's an example from the docs:

$( "#foo" ).slideUp( 300 ).delay( 800 ).fadeIn( 400 );

The only limitation (that I'm aware of) is that it doesn't give you a way to clear the timeout. If you need to do that then you're better off sticking with all the nested callbacks that setTimeout thrusts upon you.

I'm not familiar with PHP, but I think String.split is Java equivalent to PHP explode. As for implode, standart library does not provide such functionality. You just iterate over your array and build string using StringBuilder/StringBuffer. Or you can try excellent Google Guava Splitter and Joiner or split/join methods from Apache Commons StringUtils.

I used a combination of the above solutions and some trial and error to come to this solution. Took me an annoying amount of time so I hope this can help someone else in the future. I also noticed that the date picker input is not at all supported by Safari...

I am using styled-components to render a transparent date picker input as shown in the image below:

const StyledInput = styled.input`
  appearance: none;
  box-sizing: border-box;
  border: 1px solid black;
  background: transparent;
  font-size: 1.5rem;
  padding: 8px;
  ::-webkit-datetime-edit-text { padding: 0 2rem; }
  ::-webkit-datetime-edit-month-field { text-transform: uppercase; }
  ::-webkit-datetime-edit-day-field { text-transform: uppercase; }
  ::-webkit-datetime-edit-year-field { text-transform: uppercase; }
  ::-webkit-inner-spin-button { display: none; }
  ::-webkit-calendar-picker-indicator { background: transparent;}
`

For debugging purposes, you could use print(repr(data)).

To display text, always print Unicode. Don't hardcode the character encoding of your environment such as Cp850 inside your script. To decode the HTTP response, see A good way to get the charset/encoding of an HTTP response in Python.

To print Unicode to Windows console, you could use win-unicode-console package.

The .browser call has been removed in jquery 1.9 have a look at http://jquery.com/upgrade-guide/1.9/ for more details.

This is a similar answer to the one Hezi Rasheff provided, but simplified so newer python users understand what's going on (I noticed many new datascience students fetch random samples in the weirdest ways because they don't know what they are doing in python).

You can get a number of random indices from your array by using:

indices = np.random.choice(A.shape[0], amount_of_samples, replace=False)

You can then use fancy indexing with your numpy array to get the samples at those indices:

A[indices]

This will get you the specified number of random samples from your data.

You can use the autocorrect lib to spell check in python.
Example Usage:

print(spell('hte'))

In 2014 I still think my point holds:

IMHO, this discussion got blown out of proportion quite a bit. Quoting the aforementioned blog post:

Most JavaScript utility libraries, such as Underscore, Valentine, and wu, rely on the “native-first dual approach.” This approach prefers native implementations, falling back to vanilla JavaScript only if the native equivalent is not supported. But jsPerf revealed an interesting trend: the most efficient way to iterate over an array or array-like collection is to avoid the native implementations entirely, opting for simple loops instead.

As if "simple loops" and "vanilla Javascript" are more native than Array or Object method implementations. Jeez ...

It certainly would be nice to have a single source of truth, but there isn't. Even if you've been told otherwise, there is no Vanilla God, my dear. I'm sorry. The only assumption that really holds is that we are all writing JavaScript code that aims at performing well in all major browsers, knowing that all of them have different implementations of the same things. It's a bitch to cope with, to put it mildly. But that's the premise, whether you like it or not.

Maybe all of you are working on large scale projects that need twitterish performance so that you really see the difference between 850,000 (Underscore.js) vs. 2,500,000 (Lodash) iterations over a list per second right now!

I for one am not. I mean, I worked on projects where I had to address performance issues, but they were never solved or caused by neither Underscore.js nor Lodash. And unless I get hold of the real differences in implementation and performance (we're talking C++ right now) of, let’s say, a loop over an iterable (object or array, sparse or not!), I rather don't get bothered with any claims based on the results of a benchmark platform that is already opinionated.

It only needs one single update of, let’s say, Rhino to set its Array method implementations on fire in a fashion that not a single "medieval loop methods perform better and forever and whatnot" priest can argue his/her way around the simple fact that all of a sudden array methods in Firefox are much faster than his/her opinionated brainfuck. Man, you just can't cheat your runtime environment by cheating your runtime environment! Think about that when promoting ...

your utility belt

... next time.

So to keep it relevant:

• Use Underscore.js if you're into convenience without sacrificing native'ish.
• Use Lodash if you're into convenience and like its extended feature catalogue (deep copy, etc.) and if you're in desperate need of instant performance and most importantly don't mind settling for an alternative as soon as native API's outshine opinionated workarounds. Which is going to happen soon. Period.
• There's even a third solution. DIY! Know your environments. Know about inconsistencies. Read their (John-David's and Jeremy's) code. Don't use this or that without being able to explain why a consistency/compatibility layer is really needed and enhances your workflow or improves the performance of your application. It is very likely that your requirements are satisfied with a simple polyfill that you're perfectly able to write yourself. Both libraries are just plain vanilla with a little bit of sugar. They both just fight over who's serving the sweetest pie. But believe me, in the end both are only cooking with water. There's no Vanilla God so there can't be no Vanilla pope, right?

Choose whatever approach fits your needs the most. As usual. I'd prefer fallbacks on actual implementations over opinionated runtime cheats anytime, but even that seems to be a matter of taste nowadays. Stick to quality resources like http://developer.mozilla.com and http://caniuse.com and you'll be just fine.

SOLUTION

The definition of optimal can vary, but here's how to concatenate strings from different rows using regular Transact SQL, which should work fine in Azure.

;WITH Partitioned AS
(
    SELECT 
        ID,
        Name,
        ROW_NUMBER() OVER (PARTITION BY ID ORDER BY Name) AS NameNumber,
        COUNT(*) OVER (PARTITION BY ID) AS NameCount
    FROM dbo.SourceTable
),
Concatenated AS
(
    SELECT 
        ID, 
        CAST(Name AS nvarchar) AS FullName, 
        Name, 
        NameNumber, 
        NameCount 
    FROM Partitioned 
    WHERE NameNumber = 1

    UNION ALL

    SELECT 
        P.ID, 
        CAST(C.FullName + ', ' + P.Name AS nvarchar), 
        P.Name, 
        P.NameNumber, 
        P.NameCount
    FROM Partitioned AS P
        INNER JOIN Concatenated AS C 
                ON P.ID = C.ID 
                AND P.NameNumber = C.NameNumber + 1
)
SELECT 
    ID,
    FullName
FROM Concatenated
WHERE NameNumber = NameCount

EXPLANATION

The approach boils down to three steps:

1. Number the rows using OVER and PARTITION grouping and ordering them as needed for the concatenation. The result is Partitioned CTE. We keep counts of rows in each partition to filter the results later.

2. Using recursive CTE (Concatenated) iterate through the row numbers (NameNumber column) adding Name values to FullName column.

3. Filter out all results but the ones with the highest NameNumber.

Please keep in mind that in order to make this query predictable one has to define both grouping (for example, in your scenario rows with the same ID are concatenated) and sorting (I assumed that you simply sort the string alphabetically before concatenation).

I've quickly tested the solution on SQL Server 2012 with the following data:

INSERT dbo.SourceTable (ID, Name)
VALUES 
(1, 'Matt'),
(1, 'Rocks'),
(2, 'Stylus'),
(3, 'Foo'),
(3, 'Bar'),
(3, 'Baz')

The query result:

ID          FullName
----------- ------------------------------
2           Stylus
3           Bar, Baz, Foo
1           Matt, Rocks

Simplest of all solutions:

df = df.replace(r'^\s+$', np.nan, regex=True)

I had a case in where I was needing to use a data frame within a for loop function. In this case, it was the "efficient", however, keep in mind that the database was small and the iterations in the loop were very simple. But maybe the code could be useful for some one with similar conditions.

The for loop purpose was to use the raster extract function along five locations (i.e. 5 Tokio, New York, Sau Paulo, Seul & Mexico city) and each location had their respective raster grids. I had a spatial point database with more than 1000 observations allocated within the 5 different locations and I was needing to extract information from 10 different raster grids (two grids per location). Also, for the subsequent analysis, I was not only needing the raster values but also the unique ID for each observations.

After preparing the spatial data, which included the following tasks:

1. Import points shapefile with the readOGR function (rgdap package)
2. Import raster files with the raster function (raster package)
3. Stack grids from the same location into one file, with the function stack (raster package)

Here the for loop code with the use of a data frame:

1. Add stacked rasters per location into a list

raslist <- list(LOC1,LOC2,LOC3,LOC4,LOC5)

2. Create an empty dataframe, this will be the output file

TB <- data.frame(VAR1=double(),VAR2=double(),ID=character())

3. Set up for loop function

L1 <- seq(1,5,1) # the location ID is a numeric variable with values from 1 to 5 

for (i in 1:length(L1)) {
  dat=subset(points,LOCATION==i) # select corresponding points for location [i] 
  t=data.frame(extract(raslist[[i]],dat),dat$ID) # run extract function with points & raster stack for location [i]
  names(t)=c("VAR1","VAR2","ID") 
  TB=rbind(TB,t)
}

You should provide a selector to the on function:

$(document).on('change', 'input', function() {
  // Does some stuff and logs the event to the console
});

In that case, it will work as you expected. Also, it is better to specify some element instead of document.

Read this article for better understanding: http://elijahmanor.com/differences-between-jquery-bind-vs-live-vs-delegate-vs-on/

FWIW, here's the generic solution that I'm using. I'm using Bootstrap 3, but I think the general approach should work with Bootstrap 2 as well.

The solution enables popovers and adds a 'close' button for all popovers identified by the 'rel="popover"' tag using a generic block of JS code. Other than the (standard) requirement that there be a rel="popover" tag, you can put an arbitrary number of popovers on the page, and you don't need to know their IDs -- in fact they don't need IDs at all. You do need to use the 'data-title' HTML tag format to set the title attribute of your popovers, and have data-html set to "true".

The trick that I found necessary was to build an indexed map of references to the popover objects ("po_map"). Then I can add an 'onclick' handler via HTML that references the popover object via the index that JQuery gives me for it ("p_list['+index+'].popover(\'toggle\')"). That way I don't need to worry about the ids of the popover objects, since I have a map of references to the objects themselves with a JQuery-provided unique index.

Here's the javascript:

var po_map = new Object();
function enablePopovers() {
  $("[rel='popover']").each(function(index) {
    var po=$(this);
    po_map[index]=po;
    po.attr("data-title",po.attr("data-title")+
    '<button id="popovercloseid" title="close" type="button" class="close" onclick="po_map['+index+'].popover(\'toggle\')">&times;</button>');
    po.popover({});
  });
}
$(document).ready(function() { enablePopovers() });

this solution let me easily put a close button on all the popovers all across my site.

For just plotting a vector, you should use the following command:

text(your.vector, labels=your.labels, cex= labels.size, pos=labels.position)

Faster way of writing it would be...

in = open('path/to/input/file').read()
out = open('path/to/input/file', 'w')
replacements = {'zero':'0', 'temp':'bob', 'garbage':'nothing'}
for i in replacements.keys():
    in = in.replace(i, replacements[i])
out.write(in)
out.close

This eliminated a lot of the iterations that the other answers suggest, and will speed up the process for longer files.

This example in the input hello ugly world it searches for the regex bad|ugly and replaces it with nice

#!/bin/bash

# THIS FUNCTION NEEDS THREE PARAMETERS
# arg1 = input              Example:  hello ugly world
# arg2 = search regex       Example:  bad|ugly
# arg3 = replace            Example:  nice
function regex_replace()
{
  # $1 = hello ugly world
  # $2 = bad|ugly
  # $3 = nice

  # REGEX
  re="(.*?)($2)(.*)"

  if [[ $1 =~ $re ]]; then
    # if there is a match
    
    # ${BASH_REMATCH[0]} = hello ugly world
    # ${BASH_REMATCH[1]} = hello 
    # ${BASH_REMATCH[2]} = ugly
    # ${BASH_REMATCH[3]} = world    

    # hello + nice + world
    echo ${BASH_REMATCH[1]}$3${BASH_REMATCH[3]}
  else    
    # if no match return original input  hello ugly world
    echo "$1"
  fi    
}

# prints 'hello nice world'
regex_replace 'hello ugly world' 'bad|ugly' 'nice'

# to save output to a variable
x=$(regex_replace 'hello ugly world' 'bad|ugly' 'nice')
echo "output of replacement is: $x"
exit

Try this:

With xlApp.ActiveSheet.Pictures.Insert(PicPath)
    With .ShapeRange
        .LockAspectRatio = msoTrue
        .Width = 75
        .Height = 100
    End With
    .Left = xlApp.ActiveSheet.Cells(i, 20).Left
    .Top = xlApp.ActiveSheet.Cells(i, 20).Top
    .Placement = 1
    .PrintObject = True
End With

It's better not to .select anything in Excel, it is usually never necessary and slows down your code.

You can use jQuery UI and do something like this

Html:

<button id="callConfirm">Confirm!</button>

<div id="dialog" title="Confirmation Required">
  Are you sure about this?
</div>?

Javascript:

$("#dialog").dialog({
   autoOpen: false,
   modal: true,
   buttons : {
        "Confirm" : function() {
            alert("You have confirmed!");            
        },
        "Cancel" : function() {
          $(this).dialog("close");
        }
      }
    });

$("#callConfirm").on("click", function(e) {
    e.preventDefault();
    $("#dialog").dialog("open");
});

?

.toLowerCase function only exists on strings. You can call toString() on anything in javascript to get a string representation. Putting this all together:

var ans = 334;
var temp = ans.toString().toLowerCase();
alert(temp);

This has been fully answered here.

See Oracle's docs on SELECT to see how subquery factoring works, and Mark's example:

WITH employee AS (SELECT * FROM Employees)
SELECT * FROM employee WHERE ID < 20
UNION ALL
SELECT * FROM employee WHERE Sex = 'M'

I work in WordPress a lot so use PHP.

My method is to contain my HTML in a PHP Variable, and then echo the variable in data-content.

$my-data-content = '<form><input type="text"/></form>';

along with

data-content='<?php echo $my-data-content; ?>' 

You can use data-image for that. using data-image(data-URI) you can access SVG like inline.

Here is rollover effect using pure CSS and SVG.

I know it messy but you can do this way.

For a more detailed answer on creating your own colormaps, I highly suggest visiting this page

If that answer is too much work, you can quickly make your own list of colors and pass them to the color parameter. All the colormaps are in the cm matplotlib module. Let's get a list of 30 RGB (plus alpha) color values from the reversed inferno colormap. To do so, first get the colormap and then pass it a sequence of values between 0 and 1. Here, we use np.linspace to create 30 equally-spaced values between .4 and .8 that represent that portion of the colormap.

from matplotlib import cm
color = cm.inferno_r(np.linspace(.4, .8, 30))
color

array([[ 0.865006,  0.316822,  0.226055,  1.      ],
       [ 0.851384,  0.30226 ,  0.239636,  1.      ],
       [ 0.832299,  0.283913,  0.257383,  1.      ],
       [ 0.817341,  0.270954,  0.27039 ,  1.      ],
       [ 0.796607,  0.254728,  0.287264,  1.      ],
       [ 0.775059,  0.239667,  0.303526,  1.      ],
       [ 0.758422,  0.229097,  0.315266,  1.      ],
       [ 0.735683,  0.215906,  0.330245,  1.      ],
       .....

Then we can use this to plot, using the data from the original post:

import random
x = [{i: random.randint(1, 5)} for i in range(30)]
df = pd.DataFrame(x)
df.plot(kind='bar', stacked=True, color=color, legend=False, figsize=(12, 4))

See section Attributes from documentation on directives.

observing interpolated attributes: Use $observe to observe the value changes of attributes that contain interpolation (e.g. src="{{bar}}"). Not only is this very efficient but it's also the only way to easily get the actual value because during the linking phase the interpolation hasn't been evaluated yet and so the value is at this time set to undefined.

I had a similar issue:

1. On my ASP.NET MVC project, I've added a Sql Server Compact database (sdf) to my App_Data folder. VS added a reference to EntityFramework.dll, version 4.* . The web.config file was updated appropriately with the 4.* configuration.

   <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=4.4.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false"/>

2. I've added a new project to my solution (a Data Access Layer project). Here I've added an EDMX file. VS added a reference to EntityFramework.dll, version 5.0. The App.config file was updated appropriately with the 5.0 configuration

   <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=5.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />

On execution, when reading from the database the app always thrown the exception Could not load file or assembly 'EntityFramework, Version=5.0.0.0 ....

The issue was fixed by removing the EntityFramework.dll v4.0 from my MVC project. I've also updated the web.config file with the correct 5.0 version. Then everything worked as expected.

A simple way to do this is using ifelse, which is vectorized. If the condition is satisfied, we use a replacement value, otherwise we use the original value.

v <- c(3, 2, 1, 0, 4, 0)
ifelse(v == 0, 1, v)

We can avoid a named variable by using a pipe.

c(3, 2, 1, 0, 4, 0) %>% ifelse(. == 0, 1, .)

A common task is to do multiple replacements. Instead of nested ifelse statements, we can use case_when from dplyr:

case_when(v == 0 ~ 1,
          v == 1 ~ 2,
          TRUE ~ v)

Old answer:

For factor or character vectors, we can use revalue from plyr:

> revalue(c("a", "b", "c"), c("b" = "B"))
[1] "a" "B" "c"

This has the advantage of only specifying the input vector once, so we can use a pipe like

x %>% revalue(c("b" = "B"))

Judging from the examples you provide, I'm assuming that by ANNs, you mean multilayer feed-forward networks (FF nets for short), such as multilayer perceptrons, because those are in direct competition with SVMs.

One specific benefit that these models have over SVMs is that their size is fixed: they are parametric models, while SVMs are non-parametric. That is, in an ANN you have a bunch of hidden layers with sizes h₁ through h_n depending on the number of features, plus bias parameters, and those make up your model. By contrast, an SVM (at least a kernelized one) consists of a set of support vectors, selected from the training set, with a weight for each. In the worst case, the number of support vectors is exactly the number of training samples (though that mainly occurs with small training sets or in degenerate cases) and in general its model size scales linearly. In natural language processing, SVM classifiers with tens of thousands of support vectors, each having hundreds of thousands of features, is not unheard of.

Also, online training of FF nets is very simple compared to online SVM fitting, and predicting can be quite a bit faster.

EDIT: all of the above pertains to the general case of kernelized SVMs. Linear SVM are a special case in that they are parametric and allow online learning with simple algorithms such as stochastic gradient descent.

1. Select the item you want to replace (double-click it, or Ctrl - F to find it)...

2. Then do a (Ctrl - Apple - G) on Mac (aka. "Quick Find All"), to HIGHLIGHT all occurrences of the string at once.

3. Now just TYPE your replacement text directly... All selection occurrences will be replaced as you type (as if your cursor was in multiple places at once!)

Very handy...

I had to make the following changes for the popover to position below with some overlap and to show the arrow correctly.

js

case 'bottom-right':  
    tp = {top: pos.top + pos.height + 10, left: pos.left + pos.width - 40}  
    break  

css

    .popover.bottom-right .arrow {  
      left: 20px; /* MODIFIED */  
      margin-left: -11px;  
      border-top-width: 0;  
      border-bottom-color: #999;  
      border-bottom-color: rgba(0, 0, 0, 0.25);  
      top: -11px;  
    }  
    .popover.bottom-right .arrow:after {  
      top: 1px;  
      margin-left: -10px;  
      border-top-width: 0;  
      border-bottom-color: #ffffff;  
    }  

This can be extended for arrow locations elsewhere .. enjoy!

Why write custom jQuery code for Marquee... just use a plugin for jQuery - marquee() and use it like in the example below:

First include :

<script type='text/javascript' src='//cdn.jsdelivr.net/jquery.marquee/1.3.1/jquery.marquee.min.js'></script>

and then:

//proporcional speed counter (for responsive/fluid use)
var widths = $('.marquee').width()
var duration = widths * 7;

$('.marquee').marquee({
    //speed in milliseconds of the marquee
    duration: duration, // for responsive/fluid use
    //duration: 8000, // for fixed container
    //gap in pixels between the tickers
    gap: $('.marquee').width(),
    //time in milliseconds before the marquee will start animating
    delayBeforeStart: 0,
    //'left' or 'right'
    direction: 'left',
    //true or false - should the marquee be duplicated to show an effect of continues flow
    duplicated: true
});

If you can make it simpler and better I dare you all people :). Don't make your life more difficult than it should be. More about this plugin and its functionalities at: http://aamirafridi.com/jquery/jquery-marquee-plugin

The Main method is Static. You can not invoke a non-static method from a static method.

GetRandomBits()

is not a static method. Either you have to create an instance of Program

Program p = new Program();
p.GetRandomBits();

or make

GetRandomBits() static.

I solved my problem in AngularJS as follows:

var configPopOver = {
        animation: 500,
        container: 'body',
        placement: function (context, source) {
                    var elBounding = source.getBoundingClientRect();
                    var pageWidth = angular.element('body')[0].clientWidth
                    var pageHeith = angular.element('body')[0].clientHeith

                    if (elBounding.left > (pageWidth*0.34) && elBounding.width < (pageWidth*0.67)) {
                        return "left";
                    }

                    if (elBounding.left < (pageWidth*0.34) && elBounding.width < (pageWidth*0.67)) {
                        return "right";
                    }

                    if (elBounding.top < 110){
                        return "bottom";
                    }

                    return "top";
                },
        html: true
    };

This function do the position of Bootstrap popover float to the best position, based on element position.

Example for String Methods

Given a list of filenames, we want to rename all the files with extension hpp to the extension h. To do this, we would like to generate a new list called newfilenames, consisting of the new filenames. Fill in the blanks in the code using any of the methods you’ve learned thus far, like a for loop or a list comprehension.

filenames = ["program.c", "stdio.hpp", "sample.hpp", "a.out", "math.hpp", "hpp.out"]
# Generate newfilenames as a list containing the new filenames
# using as many lines of code as your chosen method requires.
newfilenames = []
for i in filenames:
    if i.endswith(".hpp"):
        x = i.replace("hpp", "h")
        newfilenames.append(x)
    else:
        newfilenames.append(i)


print(newfilenames)
# Should be ["program.c", "stdio.h", "sample.h", "a.out", "math.h", "hpp.out"]

instead of newdata you are using newdate in your predict code, verify once. and just use Coupon$estimate <- predict(model, Coupon) It will work.

You have to add the size of the legend box to the ylim range

#Plot an empty graph and legend to get the size of the legend
x <-1:10
y <-11:20
plot(x,y,type="n", xaxt="n", yaxt="n")
my.legend.size <-legend("topright",c("Series1","Series2","Series3"),plot = FALSE)

#custom ylim. Add the height of legend to upper bound of the range
my.range <- range(y)
my.range[2] <- 1.04*(my.range[2]+my.legend.size$rect$h)

#draw the plot with custom ylim
plot(x,y,ylim=my.range, type="l")
my.legend.size <-legend("topright",c("Series1","Series2","Series3"))

Well... I've found some issues in every proposed solution here.

• You should be able to choose if you want entire element to be on screen or just any part of it
• Proposed solutions fails if element is higher/wider than window and kinda covers browser window.

Here is my solution that include jQuery .fn instance function and expression. I've created more variables inside my function than I could, but for complex logical problem I like to divide it into smaller, clearly named pieces.

I'm using getBoundingClientRect method that returns element position relatively to the viewport so I don't need to care about scroll position

Useage:

$(".some-element").filter(":onscreen").doSomething();
$(".some-element").filter(":entireonscreen").doSomething();
$(".some-element").isOnScreen(); // true / false
$(".some-element").isOnScreen(true); // true / false (partially on screen)
$(".some-element").is(":onscreen"); // true / false (partially on screen)
$(".some-element").is(":entireonscreen"); // true / false 

Source:

$.fn.isOnScreen = function(partial){

    //let's be sure we're checking only one element (in case function is called on set)
    var t = $(this).first();

    //we're using getBoundingClientRect to get position of element relative to viewport
    //so we dont need to care about scroll position
    var box = t[0].getBoundingClientRect();

    //let's save window size
    var win = {
        h : $(window).height(),
        w : $(window).width()
    };

    //now we check against edges of element

    //firstly we check one axis
    //for example we check if left edge of element is between left and right edge of scree (still might be above/below)
    var topEdgeInRange = box.top >= 0 && box.top <= win.h;
    var bottomEdgeInRange = box.bottom >= 0 && box.bottom <= win.h;

    var leftEdgeInRange = box.left >= 0 && box.left <= win.w;
    var rightEdgeInRange = box.right >= 0 && box.right <= win.w;


    //here we check if element is bigger then window and 'covers' the screen in given axis
    var coverScreenHorizontally = box.left <= 0 && box.right >= win.w;
    var coverScreenVertically = box.top <= 0 && box.bottom >= win.h;

    //now we check 2nd axis
    var topEdgeInScreen = topEdgeInRange && ( leftEdgeInRange || rightEdgeInRange || coverScreenHorizontally );
    var bottomEdgeInScreen = bottomEdgeInRange && ( leftEdgeInRange || rightEdgeInRange || coverScreenHorizontally );

    var leftEdgeInScreen = leftEdgeInRange && ( topEdgeInRange || bottomEdgeInRange || coverScreenVertically );
    var rightEdgeInScreen = rightEdgeInRange && ( topEdgeInRange || bottomEdgeInRange || coverScreenVertically );

    //now knowing presence of each edge on screen, we check if element is partially or entirely present on screen
    var isPartiallyOnScreen = topEdgeInScreen || bottomEdgeInScreen || leftEdgeInScreen || rightEdgeInScreen;
    var isEntirelyOnScreen = topEdgeInScreen && bottomEdgeInScreen && leftEdgeInScreen && rightEdgeInScreen;

    return partial ? isPartiallyOnScreen : isEntirelyOnScreen;

};

$.expr.filters.onscreen = function(elem) {
  return $(elem).isOnScreen(true);
};

$.expr.filters.entireonscreen = function(elem) {
  return $(elem).isOnScreen(true);
};

In addition to other replies. If you allow html in options you can pass jQuery object to content, and it will be appended to popover's content with all events and bindings. Here is the logic from source code:

• if you pass a function it will be called to unwrap content data
• if html is not allowed content data will be applied as text
• if html allowed and content data is string it will be applied as html
• otherwise content data will be appended to popover's content container

$("#popover-button").popover({
    content: $("#popover-content"),
    html: true,
    title: "Popover title"
});

blazeroni already made it pretty clear, I just want to add few points.

• <merge> is used for optimizing layouts.It is used for reducing unnecessary nesting.
• when a layout containing <merge> tag is added into another layout,the <merge> node is removed and its child view is added directly to the new parent.

The answer John Colby gives is the right answer. However if you are a dplyr user there is also the answer sample_n:

sample_n(df, 10)

randomly samples 10 rows from the dataframe. It calls sample.int, so really is the same answer with less typing (and simplifies use in the context of magrittr since the dataframe is the first argument).

A one liner:

perl -pi.back -e 's/<PREF>/ABCD/g;' inputfile

Another option would be to use case_when

require(dplyr)

mutate(df, est = case_when(
    b == 0 ~ (a - 5)/2.53, 
    TRUE   ~ est 
))

This solution becomes even more handy if more than 2 cases need to be distinguished, as it allows to avoid nested if_else constructs.

Just throw an empty, hidden div onto your html page and give it an ID. Then you can use that for your jQuery UI dialog. You can populate the text just like you normally would with any jquery call.

Works Great with AndroidTeam's solution, however I found that I needed the ability to go back much like FrgmentTransaction.addToBackStack(null) But merely adding this will only cause the Fragment to be replaced without notifying the ViewPager. Combining the provided solution with this minor enhancement will allow you to return to the previous state by merely overriding the activity's onBackPressed() method. The biggest drawback is that it will only go back one at a time which may result in multiple back clicks

private ArrayList<Fragment> bFragments = new ArrayList<Fragment>();
private ArrayList<Integer> bPosition = new ArrayList<Integer>();

public void replaceFragmentsWithBackOut(ViewPager container, Fragment oldFragment, Fragment newFragment) {
    startUpdate(container);

    // remove old fragment

    if (mCurTransaction == null) {
         mCurTransaction = mFragmentManager.beginTransaction();
     }
    int position = getFragmentPosition(oldFragment);
     while (mSavedState.size() <= position) {
         mSavedState.add(null);
     }

     //Add Fragment to Back List
     bFragments.add(oldFragment);

     //Add Pager Position to Back List
     bPosition.add(position);

     mSavedState.set(position, null);
     mFragments.set(position, null);

     mCurTransaction.remove(oldFragment);

     // add new fragment

     while (mFragments.size() <= position) {
         mFragments.add(null);
     }
     mFragments.set(position, newFragment);
     mCurTransaction.add(container.getId(), newFragment);

    finishUpdate(container);

    // ensure getItem returns newFragemtn after calling handleGetItemInbalidated()
    handleGetItemInvalidated(container, oldFragment, newFragment);

    container.notifyItemChanged(oldFragment, newFragment);
 }


public boolean popBackImmediate(ViewPager container){
    int bFragSize = bFragments.size();
    int bPosSize = bPosition.size();

    if(bFragSize>0 && bPosSize>0){
        if(bFragSize==bPosSize){
            int last = bFragSize-1;
            int position = bPosition.get(last);

            //Returns Fragment Currently at this position
            Fragment replacedFragment = mFragments.get(position);               
            Fragment originalFragment = bFragments.get(last);

            this.replaceFragments(container, replacedFragment, originalFragment);

            bPosition.remove(last);
            bFragments.remove(last);

            return true;
        }
    }

    return false;       
}

Hope this helps someone.

Also as far as getFragmentPosition() goes it's pretty much getItem() in reverse. You know which fragments go where, just make sure you return the correct position it will be in. Here's an example:

    @Override
    protected int getFragmentPosition(Fragment fragment) {
            if(fragment.equals(originalFragment1)){
                return 0;
            }
            if(fragment.equals(replacementFragment1)){
                return 0;
            }
            if(fragment.equals(Fragment2)){
                return 1;
            }
        return -1;
    }

Interestingly enough I do not thing any of the posted solutions are good enough, because they rely on the fact that the character used is 1em wide, which does not need to be so (with maybe exception of John Magnolia's answer which however uses floats which can complicate things another way). Here is my attempt:

ul {_x000D_
  list-style-type: none;_x000D_
  margin-left: 0;_x000D_
  padding-left: 30px; /* change 30px to anything */_x000D_
  text-indent: -30px;_x000D_
}_x000D_
ul li:before {_x000D_
  content: "xy";_x000D_
  display: inline-block; _x000D_
  width: 30px;_x000D_
  text-indent: 0;_x000D_
  text-align: center; /* change this for different bullet position */_x000D_
}

<ul>_x000D_
  <li>Item 1</li>_x000D_
  <li>Item 2</li>_x000D_
  <li>Item 3 Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam</li>_x000D_
  <li>Item 4</li>_x000D_
  <li>Item 5</li>_x000D_
</ul>

This has these advantages (over other solutions):

1. It does not rely on the width of the symbol as you see in the example. I used two characters to show that it works even with wide bullets. If you try this in other solutions you get the text misaligned (in fact it is even visible with * symbol in higher zooms).
2. It gives you total control of the space used by bullets. You can replace 30px by anything (even 1em etc). Just do not forgot to change it on all three places.
3. If gives you total control of positioning of the bullet. Just replace the text-align: center; by anything to your liking. For example you may try color: red; text-align: right; padding-right: 5px; box-sizing: border-box; or if you do not like playing with border-box, just subtract the padding (5px) from width (i.e. width:25px in this example). There are lots of options.
4. It does not use floats so it can be contained anywhere.

Enjoy.

Try:

which( !is.na(p), arr.ind=TRUE)

Which I think is just as informative and probably more useful than the output you specified, But if you really wanted the list version, then this could be used:

> apply(p, 1, function(x) which(!is.na(x)) )
[[1]]
[1] 2 3

[[2]]
[1] 4 7

[[3]]
integer(0)

[[4]]
[1] 5

[[5]]
integer(0)

Or even with smushing together with paste:

lapply(apply(p, 1, function(x) which(!is.na(x)) ) , paste, collapse=", ")

The output from which function the suggested method delivers the row and column of non-zero (TRUE) locations of logical tests:

> which( !is.na(p), arr.ind=TRUE)
     row col
[1,]   1   2
[2,]   1   3
[3,]   2   4
[4,]   4   5
[5,]   2   7

Without the arr.ind parameter set to non-default TRUE, you only get the "vector location" determined using the column major ordering the R has as its convention. R-matrices are just "folded vectors".

> which( !is.na(p) )
[1]  6 11 17 24 32

I have the same problem. but when i add direction: rtl; in tabs and accordion combo but it crashes my structure.

The way to do it is add div with direction: rtl; as parent element, and for child div set direction: ltr;.

I use this first https://api.jquery.com/wrap/

$( ".your selector of child element" ).wrap( "<div class='scroll'></div>" );

then just simply work with css :)

In children div add to css

 .your_class {
            direction: ltr;    
        }

And to parent div added by jQuery with class .scroll

.scroll {
            unicode-bidi:bidi-override;
            direction: rtl;
            overflow: scroll;
            overflow-x: hidden!important;
        }

Works prefect for me

A little slower, but readable I think:

>>> s, l, m
([5, 4, 3, 2, 1, 0], [0, 1, 3, 5], [0, 0, 0, 0])
>>> d = dict(zip(l, m))
>>> d  #dict is better then using two list i think
{0: 0, 1: 0, 3: 0, 5: 0}
>>> [d.get(i, j) for i, j in enumerate(s)]
[0, 0, 3, 0, 1, 0]

You're calling both wait and notifyAll without using a synchronized block. In both cases the calling thread must own the lock on the monitor you call the method on.

From the docs for notify (wait and notifyAll have similar documentation but refer to notify for the fullest description):

This method should only be called by a thread that is the owner of this object's monitor. A thread becomes the owner of the object's monitor in one of three ways:

• By executing a synchronized instance method of that object.
• By executing the body of a synchronized statement that synchronizes on the object.
• For objects of type Class, by executing a synchronized static method of that class.

Only one thread at a time can own an object's monitor.

Only one thread will be able to actually exit wait at a time after notifyAll as they'll all have to acquire the same monitor again - but all will have been notified, so as soon as the first one then exits the synchronized block, the next will acquire the lock etc.

Swift 3 Version:

class SomeClass: UIViewController, UITextFieldDelegate { 

   @IBOutlet weak var aTextField: UITextField!


    override func viewDidLoad() {
        super.viewDidLoad()

        aTextField.delegate = self
        aTextField.addTarget(self, action: #selector(SignUpVC.textFieldDidChange), for: UIControlEvents.editingChanged)        
    }

   func textFieldDidChange(_ textField: UITextField) {

       //TEXT FIELD CHANGED..SECRET STUFF

   }

}

Don't forget to set the delegate.

You say you've had problems with Navicat. For the record, I use Navicat and I haven't experienced the issue you describe. You might want to dig around, see if there's a reason for your problem and/or a solution, because given the question asked, my first recommendation would have been Navicat.

But if you want alternative suggestions, here are a few that I know of and have used:

MySQL has its own tool which you can download for free, called MySQL Workbench. Download it from here: http://wb.mysql.com/. My experience is that it's powerful, but I didn't really like the UI. But that's just my personal taste.

Another free program you might want to try is HeidiSQL. It's more similar to Navicat than MySQL Workbench. A colleague of mine loves it.

(interesting to note, by the way, that MariaDB (the forked version of MySQL) is currently shipped with HeidiSQL as its GUI tool)

Finally, if you're running a web server on your machine, there's always the option of a browser-based tool like PHPMyAdmin. It's actually a surprisingly powerful piece of software.

This is similar to some of the above answers, but with this, you can specify if you want to remove rows with a percentage of missing values greater-than or equal-to a given percent (with the argument pct)

drop_rows_all_na <- function(x, pct=1) x[!rowSums(is.na(x)) >= ncol(x)*pct,]

Where x is a dataframe and pct is the threshold of NA-filled data you want to get rid of.

pct = 1 means remove rows that have 100% of its values NA. pct = .5 means remome rows that have at least half its values NA

go through the below coding to get the separate group replacement.

new_bib = Regex.Replace(new_bib, @"(?s)(\\bibitem\[[^\]]+\]\{" + pat4 + @"\})[\s\n\v]*([\\\{\}a-zA-Z\.\s\,\;\\\#\\\$\\\%\\\&\*\@\\\!\\\^+\-\\\=\\\~\\\:\\\" + dblqt + @"\\\;\\\`\\\']{20,70})", delegate(Match mts)
                    {
                           var fg = mts.Groups[0].Value.ToString(); 
                           var fs = mts.Groups[1].Value.ToString();
                           var fss = mts.Groups[2].Value.ToString();
                               fss = Regex.Replace(fss, @"[\\\{\}\\\#\\\$\\\%\\\&\*\@\\\!\\\^+\-\\\=\\\~\\\:\\\" + dblqt + @"\\\;\\\`\\\']+", "");
                           return "<augroup>" + fss + "</augroup>" + fs;
                    }, RegexOptions.IgnoreCase);

In Unix systems the end of a line is represented with a line feed (LF). In windows a line is represented with a carriage return (CR) and a line feed (LF) thus (CRLF). when you get code from git that was uploaded from a unix system they will only have an LF.

If you are a single developer working on a windows machine, and you don't care that git automatically replaces LFs to CRLFs, you can turn this warning off by typing the following in the git command line

git config core.autocrlf true

If you want to make an intelligent decision how git should handle this, read the documentation

Here is a snippet

Formatting and Whitespace

Formatting and whitespace issues are some of the more frustrating and subtle problems that many developers encounter when collaborating, especially cross-platform. It’s very easy for patches or other collaborated work to introduce subtle whitespace changes because editors silently introduce them, and if your files ever touch a Windows system, their line endings might be replaced. Git has a few configuration options to help with these issues.

core.autocrlf

If you’re programming on Windows and working with people who are not (or vice-versa), you’ll probably run into line-ending issues at some point. This is because Windows uses both a carriage-return character and a linefeed character for newlines in its files, whereas Mac and Linux systems use only the linefeed character. This is a subtle but incredibly annoying fact of cross-platform work; many editors on Windows silently replace existing LF-style line endings with CRLF, or insert both line-ending characters when the user hits the enter key.

Git can handle this by auto-converting CRLF line endings into LF when you add a file to the index, and vice versa when it checks out code onto your filesystem. You can turn on this functionality with the core.autocrlf setting. If you’re on a Windows machine, set it to true – this converts LF endings into CRLF when you check out code:

$ git config --global core.autocrlf true

If you’re on a Linux or Mac system that uses LF line endings, then you don’t want Git to automatically convert them when you check out files; however, if a file with CRLF endings accidentally gets introduced, then you may want Git to fix it. You can tell Git to convert CRLF to LF on commit but not the other way around by setting core.autocrlf to input:

$ git config --global core.autocrlf input

This setup should leave you with CRLF endings in Windows checkouts, but LF endings on Mac and Linux systems and in the repository.

If you’re a Windows programmer doing a Windows-only project, then you can turn off this functionality, recording the carriage returns in the repository by setting the config value to false:

$ git config --global core.autocrlf false

You can use

text.replace('old', 'new')

And to change multiple values in one string at once, for example to change # to string v and _ to string w:

text.replace(/#|_/g,function(match) {return (match=="#")? v: w;});

This is my c++11 style solution. parameter 'base' is for base class of all sub-classes. creators, are std::function objects to create sub-class instances, might be a binding to your sub-class' static member function 'create(some args)'. This maybe not perfect but works for me. And it is kinda 'general' solution.

template <class base, class... params> class factory {
public:
  factory() {}
  factory(const factory &) = delete;
  factory &operator=(const factory &) = delete;

  auto create(const std::string name, params... args) {
    auto key = your_hash_func(name.c_str(), name.size());
    return std::move(create(key, args...));
  }

  auto create(key_t key, params... args) {
    std::unique_ptr<base> obj{creators_[key](args...)};
    return obj;
  }

  void register_creator(const std::string name,
                        std::function<base *(params...)> &&creator) {
    auto key = your_hash_func(name.c_str(), name.size());
    creators_[key] = std::move(creator);
  }

protected:
  std::unordered_map<key_t, std::function<base *(params...)>> creators_;
};

An example on usage.

class base {
public:
  base(int val) : val_(val) {}

  virtual ~base() { std::cout << "base destroyed\n"; }

protected:
  int val_ = 0;
};

class foo : public base {
public:
  foo(int val) : base(val) { std::cout << "foo " << val << " \n"; }

  static foo *create(int val) { return new foo(val); }

  virtual ~foo() { std::cout << "foo destroyed\n"; }
};

class bar : public base {
public:
  bar(int val) : base(val) { std::cout << "bar " << val << "\n"; }

  static bar *create(int val) { return new bar(val); }

  virtual ~bar() { std::cout << "bar destroyed\n"; }
};

int main() {
  common::factory<base, int> factory;

  auto foo_creator = std::bind(&foo::create, std::placeholders::_1);
  auto bar_creator = std::bind(&bar::create, std::placeholders::_1);

  factory.register_creator("foo", foo_creator);
  factory.register_creator("bar", bar_creator);

  {
    auto foo_obj = std::move(factory.create("foo", 80));
    foo_obj.reset();
  }

  {
    auto bar_obj = std::move(factory.create("bar", 90));
    bar_obj.reset();
  }
}

The sample config you provided is actually valid YAML. In fact, YAML meets all of your demands, is implemented in a large number of languages, and is extremely human friendly. I would highly recommend you use it. The PyYAML project provides a nice python module, that implements YAML.

To use the yaml module is extremely simple:

import yaml
config = yaml.safe_load(open("path/to/config.yml"))

String newstring  = "";
String target2 = "fooBar";
newstring = target2.substring("foo".length()).trim();   
logger.debug("target2: {}",newstring); 
// output: target2: Bar
    
String target3 = "FooBar";
newstring = target3.substring("foo".length()).trim();
logger.debug("target3: {}",newstring); 
// output: target3: Bar

You can use the position:fixed;, but without set left and top. Then you will push it to the right using margin-left, to position it in the right position you wish.

Check a demo here: http://jsbin.com/icili5

public static string ToFormattedCurrencyString(
    this decimal currencyAmount,
    string isoCurrencyCode,
    CultureInfo userCulture)
{
    var userCurrencyCode = new RegionInfo(userCulture.Name).ISOCurrencySymbol;

if (userCurrencyCode == isoCurrencyCode)
{
    return currencyAmount.ToString("C", userCulture);
}

return string.Format(
    "{0} {1}", 
    isoCurrencyCode, 
    currencyAmount.ToString("N2", userCulture));

}

The problem is an issue with an old version of OpenSSL being incompatible with pip 1.3.1 and above versions. The easy workaround for now, is to install pip 1.2.1, which does not require SSL:

Installing Pip on Windows:

1. Download pip 1.2.1 from https://pypi.python.org/packages/source/p/pip/pip-1.2.1.tar.gz
2. Extract the pip-1.2.1.tar.gz file
3. Change directory to the extracted folder: cd <path to extracted folder>/pip-1.2.1
4. Run python setup.py install
5. Now make sure C:\Python27\Scripts is in PATH because pip is installed in the C:\Python27\Scripts directory unlike C:\Python27\Lib\site-packages where Python packages are normally installed

Now try to install any package using pip.

For example, to install the requests package using pip, run this from cmd:

pip install requests

Whola! requests will be successfully installed and you will get a success message.

You can simply specify a series of images like this:

\includegraphics<1>{A}
\includegraphics<2>{B}
\includegraphics<3>{C}

This will produce three slides with the images A to C in exactly the same position.

I'm a little late to this party, but I think I have something useful to add.

Kekoa's answer is great but, as RonLugge mentions, it can make the button no longer respect sizeToFit or, more importantly, can cause the button to clip its content when it is intrinsically sized. Yikes!

First, though,

A brief explanation of how I believe imageEdgeInsets and titleEdgeInsets work:

The docs for imageEdgeInsets have the following to say, in part:

Use this property to resize and reposition the effective drawing rectangle for the button image. You can specify a different value for each of the four insets (top, left, bottom, right). A positive value shrinks, or insets, that edge—moving it closer to the center of the button. A negative value expands, or outsets, that edge.

I believe that this documentation was written imagining that the button has no title, just an image. It makes a lot more sense thought of this way, and behaves how UIEdgeInsets usually do. Basically, the frame of the image (or the title, with titleEdgeInsets) is moved inwards for positive insets and outwards for negative insets.

OK, so what?

I'm getting there! Here's what you have by default, setting an image and a title (the button border is green just to show where it is):

When you want spacing between an image and a title, without causing either to be crushed, you need to set four different insets, two on each of the image and title. That's because you don't want to change the sizes of those elements' frames, but just their positions. When you start thinking this way, the needed change to Kekoa's excellent category becomes clear:

@implementation UIButton(ImageTitleCentering)

- (void)centerButtonAndImageWithSpacing:(CGFloat)spacing {
    CGFloat insetAmount = spacing / 2.0;
    self.imageEdgeInsets = UIEdgeInsetsMake(0, -insetAmount, 0, insetAmount);
    self.titleEdgeInsets = UIEdgeInsetsMake(0, insetAmount, 0, -insetAmount);
}

@end

But wait, you say, when I do that, I get this:

Oh yeah! I forgot, the docs warned me about this. They say, in part:

This property is used only for positioning the image during layout. The button does not use this property to determine intrinsicContentSize and sizeThatFits:.

But there is a property that can help, and that's contentEdgeInsets. The docs for that say, in part:

The button uses this property to determine intrinsicContentSize and sizeThatFits:.

That sounds good. So let's tweak the category once more:

@implementation UIButton(ImageTitleCentering)

- (void)centerButtonAndImageWithSpacing:(CGFloat)spacing {
    CGFloat insetAmount = spacing / 2.0;
    self.imageEdgeInsets = UIEdgeInsetsMake(0, -insetAmount, 0, insetAmount);
    self.titleEdgeInsets = UIEdgeInsetsMake(0, insetAmount, 0, -insetAmount);
    self.contentEdgeInsets = UIEdgeInsetsMake(0, insetAmount, 0, insetAmount);
}

@end

And what do you get?

Looks like a winner to me.

Working in Swift and don't want to do any thinking at all? Here's the final version of the extension in Swift:

extension UIButton {
    func centerTextAndImage(spacing: CGFloat) {
        let insetAmount = spacing / 2
        imageEdgeInsets = UIEdgeInsets(top: 0, left: -insetAmount, bottom: 0, right: insetAmount)
        titleEdgeInsets = UIEdgeInsets(top: 0, left: insetAmount, bottom: 0, right: -insetAmount)
        contentEdgeInsets = UIEdgeInsets(top: 0, left: insetAmount, bottom: 0, right: insetAmount)
    }
}

An easy alternative that works for me is to insert the svg code into a div. This simple example uses javascript to manipulate the div innerHTML.

svg = '<svg height=150>'; 
svg+= '<rect height=100% fill=green /><circle cx=150 cy=75 r=60 fill=yellow />';
svg+= '<text x=150 y=95 font-size=60 text-anchor=middle fill=red>IIIIIII</text></svg>';
document.all.d1.innerHTML=svg;

<div id='d1' style="float:right;"></div><hr>

As per the official documents, it's not anymore advisable to use matrix class since it will be removed in the future.

https://numpy.org/doc/stable/reference/generated/numpy.matrix.html

As other answers already state that you can achieve all the operations with NumPy arrays.

It is not clear from your question what the criteria for deciding what strings to remove is, but if you have or can make a list of the strings that you want to remove , you could do the following:

my_strings = ['a','b','c','d','e']
undesirable_strings = ['b','d']
for undesirable_string in undesirable_strings:
    for i in range(my_strings.count(undesirable_string)):
        my_strings.remove(undesirable_string)

which changes my_strings to ['a', 'c', 'e']

You can use the RegExp object:

var regexstring = "whatever";
var regexp = new RegExp(regexstring, "gi");
var str = "whateverTest";
var str2 = str.replace(regexp, "other");
document.write(str2);

Then you can construct regexstring in any way you want.

You can read more about it here.

I don't know if this helps but I just installed Server 2008 Express and was disappointed when I couldn't find the query analyzer but I was able to use the command line 'sqlcmd' to access my server. It is a pain to use but it works. You can write your code in a text file then import it using the sqlcmd command. You also have to end your query with a new line and type the word 'go'.

Example of query file named test.sql:
use master;
select name, crdate from sysdatabases where xtype='u' order by crdate desc;
go

Example of sqlcmd:
sqlcmd -S %computername%\RLH -d play -i "test.sql" -o outfile.sql & notepad outfile.sql

Using the AWS 'user data' and 'meta data' APIs its possible to write a script which wraps puppet to start a puppet run with a custom cert name.

First start an aws instance with custom user data: 'role:webserver'

#!/bin/bash

# Find the name from the user data passed in on instance creation
USER=$(curl -s "http://169.254.169.254/latest/user-data")
IFS=':' read -ra UDATA <<< "$USER"

# Find the instance ID from the meta data api
ID=$(curl -s "http://169.254.169.254/latest/meta-data/instance-id")
CERTNAME=${UDATA[1]}.$ID.aws

echo "Running Puppet for certname: " $CERTNAME
puppet agent -t --certname=$CERTNAME 

This calls puppet with a certname like 'webserver.i-hfg453.aws' you can then create a node manifest called 'webserver' and puppets 'fuzzy node matching' will mean it is used to provision all webservers.

This example assumes you build on a base image with puppet installed etc.

Benefits:

1) You don't have to pass round your credentials

2) You can be as granular as you like with the role configs.

Simple solution:

# touch filename

will do all OK.

I assume this was not a valid option when this was originally asked, but you can now use document.getElementsByClassName('');. For example:

var elements = document.getElementsByClassName(names); // or:
var elements = rootElement.getElementsByClassName(names);

See the MDN documentation for more.

Using javascript seems to be unnecessary if you choose CSS3.

By using :before selector, you can do this in two lines of CSS. (no script involved).

Another advantage of this approach is that it does not rely on <label> tag and works even it is missing.

Note: in browsers without CSS3 support, checkboxes will look normal. (backward compatible).

input[type=checkbox]:before { content:""; display:inline-block; width:12px; height:12px; background:red; }
input[type=checkbox]:checked:before { background:green; }?

You can see a demo here: http://jsfiddle.net/hqZt6/1/

I threw together a small test implementation of this. The basic idea is to call format and pass in the format string, and a map of objects, and the names that they have locally.

The output of the following is:

My dog is named fido, and Jane Doe owns him.

public class StringFormatter {

    private static final String fieldStart = "\\$\\{";
    private static final String fieldEnd = "\\}";

    private static final String regex = fieldStart + "([^}]+)" + fieldEnd;
    private static final Pattern pattern = Pattern.compile(regex);

    public static String format(String format, Map<String, Object> objects) {
        Matcher m = pattern.matcher(format);
        String result = format;
        while (m.find()) {
            String[] found = m.group(1).split("\\.");
            Object o = objects.get(found[0]);
            Field f = o.getClass().getField(found[1]);
            String newVal = f.get(o).toString();
            result = result.replaceFirst(regex, newVal);
        }
        return result;
    }

    static class Dog {
        public String name;
        public String owner;
        public String gender;
    }

    public static void main(String[] args) {
        Dog d = new Dog();
        d.name = "fido";
        d.owner = "Jane Doe";
        d.gender = "him";
        Map<String, Object> map = new HashMap<String, Object>();
        map.put("d", d);
        System.out.println(
           StringFormatter.format(
                "My dog is named ${d.name}, and ${d.owner} owns ${d.gender}.", 
                map));
    }
}

Note: This doesn't compile due to unhandled exceptions. But it makes the code much easier to read.

Also, I don't like that you have to construct the map yourself in the code, but I don't know how to get the names of the local variables programatically. The best way to do it, is to remember to put the object in the map as soon as you create it.

The following example produces the results that you want from your example:

public static void main(String[] args) {
    Map<String, Object> map = new HashMap<String, Object>();
    Site site = new Site();
    map.put("site", site);
    site.name = "StackOverflow.com";
    User user = new User();
    map.put("user", user);
    user.name = "jjnguy";
    System.out.println(
         format("Hello ${user.name},\n\tWelcome to ${site.name}. ", map));
}

_{I should also mention that I have no idea what Velocity is, so I hope this answer is relevant.}

I prefer the following one-liner approach using str.rsplit():

my_filename.rsplit('.', 1)[0] + '.jpg'

Example:

>>> my_filename = '/home/user/somefile.txt'
>>> my_filename.rsplit('.', 1)
>>> ['/home/user/somefile', 'txt']

The li element supports an onclick event.

<ul>
<li onclick="location.href = 'http://stackoverflow.com/questions/3486110/make-a-list-item-clickable-html-css';">Make A List Item Clickable</li>
</ul>

I just came accross the answer from Lizard which is extremely helpful - especially when you do some sorting. Isn't is beautiful how many chars we need to say mostly the same ;)

If anyone else if looking for a all-in solution (as far as the comments above tell), here's the copy&paste:

For multiple datetime columns with no header, and a lot of columns, say my datetime fields are in columns 36 and 38, and I want them read in as character fields:

data<-read.csv("test.csv", head=FALSE,   colClasses=c("V36"="character","V38"="character"))                        

I was able to use Joey's Answer to create a function:

Use it as:

@echo off
SETLOCAL ENABLEDELAYEDEXPANSION

SET "MYTEXT=jump over the chair"
echo !MYTEXT!
call:ReplaceText "!MYTEXT!" chair table RESULT
echo !RESULT!

GOTO:EOF

And these Functions to the bottom of your Batch File.

:FUNCTIONS
@REM FUNCTIONS AREA
GOTO:EOF
EXIT /B

:ReplaceText
::Replace Text In String
::USE:
:: CALL:ReplaceText "!OrginalText!" OldWordToReplace NewWordToUse  Result
::Example
::SET "MYTEXT=jump over the chair"
::  echo !MYTEXT!
::  call:ReplaceText "!MYTEXT!" chair table RESULT
::  echo !RESULT!
::
:: Remember to use the "! on the input text, but NOT on the Output text.
:: The Following is Wrong: "!MYTEXT!" !chair! !table! !RESULT!
:: ^^Because it has a ! around the chair table and RESULT
:: Remember to add quotes "" around the MYTEXT Variable when calling.
:: If you don't add quotes, it won't treat it as a single string
::

set "OldWord=%~2"
set "NewWord=%~3"
call set OrginalText=%%OrginalText:!OldWord!=!NewWord!%%
SET %4=!OrginalText!

And remember you MUST add "SETLOCAL ENABLEDELAYEDEXPANSION" to the top of your batch file or else none of this will work properly.

SETLOCAL ENABLEDELAYEDEXPANSION
@REM # Remember to add this to the top of your batch file.

$output = preg_replace('/\s+/', ' ',$input);

\s is shorthand for [ \t\n\r]. Multiple spaces will be replaced with single space.

The difference between .dylib and .so on mac os x is how they are compiled. For .so files you use -shared and for .dylib you use -dynamiclib. Both .so and .dylib are interchangeable as dynamic library files and either have a type as DYLIB or BUNDLE. Heres the readout for different files showing this.

libtriangle.dylib:
Mach header
      magic cputype cpusubtype  caps    filetype ncmds sizeofcmds      flags
MH_MAGIC_64  X86_64        ALL  0x00       DYLIB    17       1368   NOUNDEFS DYLDLINK TWOLEVEL NO_REEXPORTED_DYLIBS



libtriangle.so:
Mach header
      magic cputype cpusubtype  caps    filetype ncmds sizeofcmds      flags
MH_MAGIC_64  X86_64        ALL  0x00       DYLIB    17       1256   NOUNDEFS DYLDLINK TWOLEVEL NO_REEXPORTED_DYLIBS

triangle.so:
Mach header
      magic cputype cpusubtype  caps    filetype ncmds sizeofcmds      flags
MH_MAGIC_64  X86_64        ALL  0x00      BUNDLE    16       1696   NOUNDEFS DYLDLINK TWOLEVEL

The reason the two are equivalent on Mac OS X is for backwards compatibility with other UNIX OS programs that compile to the .so file type.

Compilation notes: whether you compile a .so file or a .dylib file you need to insert the correct path into the dynamic library during the linking step. You do this by adding -install_name and the file path to the linking command. If you dont do this you will run into the problem seen in this post: Mac Dynamic Library Craziness (May be Fortran Only).

Call this before the query:

set define off;

Alternatively, hacky:

update t set country = 'Trinidad and Tobago' where country = 'trinidad &' || ' tobago';

From Tuning SQL*Plus:

SET DEFINE OFF disables the parsing of commands to replace substitution variables with their values.

Swift 3/4 with @IBDesignable

While almost all the above solutions work fine but I would suggest an @IBDesignable custom class for this.

@IBDesignable
class CustomLabel: UILabel {

    /*
    // Only override draw() if you perform custom drawing.
    // An empty implementation adversely affects performance during animation.
    override func draw(_ rect: CGRect) {
        // Drawing code
    }
    */

    @IBInspectable var borderColor: UIColor = UIColor.white {
        didSet {
            layer.borderColor = borderColor.cgColor
        }
    }

    @IBInspectable var borderWidth: CGFloat = 2.0 {
        didSet {
            layer.borderWidth = borderWidth
        }
    }

    @IBInspectable var cornerRadius: CGFloat = 0.0 {
        didSet {
            layer.cornerRadius = cornerRadius
        }
    }
}

You should use different methods for different use cases:

1. If you want to emphasise a phrase, use <em>.
2. The <i> tag has a new meaning in HTML5, representing "a span of text in an alternate voice or mood". So you should use this tag for things like thoughts/asides or idiomatic phrases. The spec also suggests ship names (but no longer suggests book/song/movie names; use <cite> for that instead).
3. If the italicised text is part of a larger context, say an introductory paragraph, you should attach the CSS style to the larger element, i.e. p.intro { font-style: italic; }

While this question was asked about SQL Server 2005, it's worth noting that as of Sql Server 2017, the request can be done with the new TRANSLATE function.

Try this style instead, it modifies the template itself. In there you can change everything you need to transparent:

It is useful for annotating your classes, either at the method, class, or field level, something about that class that is not quite related to the class.

You could have your own annotations, used to mark certain classes as test-use only. It could simply be for documentation purposes, or you could enforce it by filtering it out during your compile of a production release candidate.

You could use annotations to store some meta data, like in a plugin framework, e.g., name of the plugin.

Its just another tool, its has many purposes.

(1) No (unfortunately). Edit: The other answers are right, per-user configuration is usually stored in dot-files or dot-directories in the users home directory. Anything above user level often is a lot of guesswork.

(2) System-wide ini file -> user ini file -> environment -> command line options (going from lowest to highest precedence)

FYI

In the new language Kotlin, you can use "String Templates" in your source code directly, no 3rd party library or template engine need to do the variable replacement.

It is a feature of the language itself.

See: https://kotlinlang.org/docs/reference/basic-types.html#string-templates

Unfortunately I can't comment with my newbie reputation, but I have a solution for the issue of the screen going blank, or at least this is what worked for me. Instead of setting the wrapper class inside of the errorPlacement function, set it immediately when you're setting the wrapper type.

$('#myForm').validate({
    errorElement: "div",
    wrapper: "div class=\"message\"",
    errorPlacement: function(error, element) {
        offset = element.offset();
        error.insertBefore(element);
        //error.addClass('message');  // add a class to the wrapper
        error.css('position', 'absolute');
        error.css('left', offset.left + element.outerWidth() + 5);
        error.css('top', offset.top - 3);
    }

});

I'm assuming doing it this way allows the validator to know which div elements to remove, instead of all of them. Worked for me but I'm not entirely sure why, so if someone could elaborate that might help others out a ton.

do wget -r -l0 www.oldsite.com

Then just find www.oldsite.com would reveal all urls, I believe.

Alternatively, just serve that custom not-found page on every 404 request! I.e. if someone used the wrong link, he would get the page telling that page wasn't found, and making some hints about site's content.

The VARCHAR(MAX) type is a replacement for TEXT. The basic difference is that a TEXT type will always store the data in a blob whereas the VARCHAR(MAX) type will attempt to store the data directly in the row unless it exceeds the 8k limitation and at that point it stores it in a blob.

Using the LIKE statement is identical between the two datatypes. The additional functionality VARCHAR(MAX) gives you is that it is also can be used with = and GROUP BY as any other VARCHAR column can be. However, if you do have a lot of data you will have a huge performance issue using these methods.

In regard to if you should use LIKE to search, or if you should use Full Text Indexing and CONTAINS. This question is the same regardless of VARCHAR(MAX) or TEXT.

If you are searching large amounts of text and performance is key then you should use a Full Text Index.

LIKE is simpler to implement and is often suitable for small amounts of data, but it has extremely poor performance with large data due to its inability to use an index.

Although jQuery Maphilight plugin does the job, it relies on the outdated verbose imagemap in your html. I would prefer to keep the mapcoordinates external. This could be as JS with the jquery imagemap plugin but it lacks hover states. A nice solution is googles geomap visualisation in flash and JS. But the opensource future for this kind of vectordata however is svg, considering svg support accross all modern browsers, and googles svgweb for a flash convert for IE, why not a jquery plugin to add links and hoverstates to a svg map, like the JS demo here? That way you also avoid the complex step of transforming a vectormap to a imagemap coordinates.

NSString *stringreplace=[yourString stringByReplacingOccurrencesOfString:@"search" withString:@"new_string"];

If accessibility reasons is important then use the first variant (when customer want to see image without styles)

<div id="logo">
    <a href="">
        <img src="logo.png" alt="Stack Overflow" />
    </a>
</div>

No need to conform imaginary SEO requirements, because the HTML code above has correct structure and only you should decide does this suitable for you visitors.

Also you can use the variant with less HTML code

<h1 id="logo">
  <a href=""><span>Stack Overflow</span></a>
</h1>

/* position code, it may be absolute position or normal - depends on other parts of your site */
#logo {
  ...
}

#logo a {
   display:block;
   width: actual_image_width;
   height: actual_image_height;
   background: url(image.png) no-repeat left top;
}

/* for accessibility reasons - without styles variant*/
#logo a span {display: none}

Please note that I have removed all other CSS styles and hacks because they didn't correspond to the task. They may be usefull in particular cases only.

Thanks for the discussion, this method also works (VB):

Public Function StringCentering(ByVal s As String, ByVal desiredLength As Integer) As String
    If s.Length >= desiredLength Then Return s
    Dim firstpad As Integer = (s.Length + desiredLength) / 2
    Return s.PadLeft(firstpad).PadRight(desiredLength)
End Function

1. StringCentering() takes two input values and it returns a formatted string.
2. When length of s is greater than or equal to deisredLength, the function returns the original string.
3. When length of s is smaller than desiredLength, it will be padded both ends.
4. Due to character spacing is integer and there is no half-space, we can have an uneven split of space. In this implementation, the greater split goes to the leading end.
5. The function requires .NET Framework due to PadLeft() and PadRight().
6. In the last line of the function, binding is from left to right, so firstpad is applied followed by the desiredLength pad.

Here is the C# version:

public string StringCentering(string s, int desiredLength)
{
    if (s.Length >= desiredLength) return s;
    int firstpad = (s.Length + desiredLength) / 2;
    return s.PadLeft(firstpad).PadRight(desiredLength);
}

To aid understanding, integer variable firstpad is used. s.PadLeft(firstpad) applies the (correct number of) leading white spaces. The right-most PadRight(desiredLength) has a lower binding finishes off by applying trailing white spaces.

Don't forget that you can always cut and paste into the minibuffer.

So you can just copy a newline character (or any string) from your buffer, then yank it when prompted for the replacement text.

I have solved lazy initialisation and field access here Hibernate one-to-one: getId() without fetching entire object

I just posted a Notepad++ plugin to convert tabs to spaces. Yes, it converts tabs in the middle of a line. Yes, it takes into account other characters within the tabbed field. Check it out.

Here is an example of an AWK I used a while ago. It is an AWK that prints new AWKS. AWK and SED being similar it may be a good template.

ls | awk '{ print "awk " "'"'"'"  " {print $1,$2,$3} " "'"'"'"  " " $1 ".old_ext > " $1 ".new_ext"  }' > for_the_birds

It looks excessive, but somehow that combination of quotes works to keep the ' printed as literals. Then if I remember correctly the vaiables are just surrounded with quotes like this: "$1". Try it, let me know how it works with SED.

I'm not certain on what it is you're trying to achieve. But maybe you can use this:

$var =~ s/^start/foo/;
$var =~ s/end$/bar/;

I.e. just leave the middle alone and replace the start and end.

Create your own unistd.h header and include the needed headers for function prototypes.

I made a Prototype Version of this:

String.prototype.strip = function() {
  var translate_re = /[öäüÖÄÜß ]/g;
  var translate = {
    "ä":"a", "ö":"o", "ü":"u",
    "Ä":"A", "Ö":"O", "Ü":"U",
    " ":"_", "ß":"ss"   // probably more to come
  };
    return (this.replace(translate_re, function(match){
        return translate[match];})
    );
};

Use like:

var teststring = 'ä ö ü Ä Ö Ü ß';
teststring.strip();

This will will change the String to a_o_u_A_O_U_ss

As mentioned on the addMethod documentation:

Please note: While the temptation is great to add a regex method that checks it's parameter against the value, it is much cleaner to encapsulate those regular expressions inside their own method. If you need lots of slightly different expressions, try to extract a common parameter. A library of regular expressions: http://regexlib.com/DisplayPatterns.aspx

So yes, you have to add a method for each regular expression. The overhead is minimal, while it allows you to give the regex a name (not to be underestimated), a default message (handy) and the ability to reuse it a various places, without duplicating the regex itself over and over.

I also faced this ? issue. Meanwhile I ran into three cases where it happened:

1. substr()

   I was using substr() on a UTF8 string which cut UTF8 characters, thus the cut chars could not be displayed correctly. Use mb_substr($utfstring, 0, 10, 'utf-8'); instead. Credits

2. htmlspecialchars()

   Another problem was using htmlspecialchars() on a UTF8 string. The fix is to use: htmlspecialchars($utfstring, ENT_QUOTES, 'UTF-8');

3. preg_replace()

   Lastly I found out that preg_replace() can lead to problems with UTF. The code $string = preg_replace('/[^A-Za-z0-9ÄäÜüÖöß]/', ' ', $string); for example transformed the UTF string "F(×)=2×-3" into "F ? 2? ". The fix is to use mb_ereg_replace() instead.

I hope this additional information will help to get rid of such problems.

Regex.Replace(strInput, strToken.Replace("$", "[$]"), strReplaceWith, RegexOptions.IgnoreCase);

Generally, placement new is used to get rid of allocation cost of a 'normal new'.

Another scenario where I used it is a place where I wanted to have access to the pointer to an object that was still to be constructed, to implement a per-document singleton.

Adding the switches for subdirectories and verification work just fine. echo n | xcopy/-Y/s/e/v c:\source*.* c:\Dest\

The library I've used is ini4j. It is lightweight and parses the ini files with ease. Also it uses no esoteric dependencies to 10,000 other jar files, as one of the design goals was to use only the standard Java API

This is an example on how the library is used:

Ini ini = new Ini(new File(filename));
java.util.prefs.Preferences prefs = new IniPreferences(ini);
System.out.println("grumpy/homePage: " + prefs.node("grumpy").get("homePage", null));

This is not how Vim's tabs are designed to be used. In fact, they're misnamed. A better name would be "viewport" or "layout", because that's what a tab is—it's a different layout of windows of all of your existing buffers.

Trying to beat Vim into 1 tab == 1 buffer is an exercise in futility. Vim doesn't know or care and it will not respect it on all commands—in particular, anything that uses the quickfix buffer (:make, :grep, and :helpgrep are the ones that spring to mind) will happily ignore tabs and there's nothing you can do to stop that.

Instead:

• :set hidden
  If you don't have this set already, then do so. It makes vim work like every other multiple-file editor on the planet. You can have edited buffers that aren't visible in a window somewhere.
• Use :bn, :bp, :b #, :b name, and ctrl-6 to switch between buffers. I like ctrl-6 myself (alone it switches to the previously used buffer, or #ctrl-6 switches to buffer number #).
• Use :ls to list buffers, or a plugin like MiniBufExpl or BufExplorer.

Not exactly what you ask for, but I've found it easier to just all agree on a coding standard astyle can generate and then automate the process.

Under use strict, say:

(my $new = $original) =~ s/foo/bar/;

instead.

There is an easy way to get Jobs' Owners info from multiple instances by PowerShell:

{
    ## - Add Code block:

The two errors you have in your code are very different.

The first problem is that you're initializing and populating your Map in the body of the class without a statement. You can either have a static Map and a static {//TODO manipulate Map} statement in the body of the class, or initialize and populate the Map in a method or in the class' constructor.

The second problem is that you cannot treat a Map syntactically like an array, so the statement data["John"] = "Taxi Driver"; should be replaced by data.put("John", "Taxi Driver"). If you already have a "John" key in your HashMap, its value will be replaced with "Taxi Driver".

I had a same problem because I installed both of python2.7 and python3. when I run program with python3 I received same error. I install scipy with this command and problem has been solved:

sudo apt-get install python3-scipy

Other answers already on Stackoverflow:

• How do I install modules locally without root access...
• How can I use a new Perl module without install permissions?

From perlfaq8:

When you build modules, tell Perl where to install the modules.

For Makefile.PL-based distributions, use the INSTALL_BASE option when generating Makefiles:

perl Makefile.PL INSTALL_BASE=/mydir/perl

You can set this in your CPAN.pm configuration so modules automatically install in your private library directory when you use the CPAN.pm shell:

% cpan
cpan> o conf makepl_arg INSTALL_BASE=/mydir/perl
cpan> o conf commit

For Build.PL-based distributions, use the --install_base option:

perl Build.PL --install_base /mydir/perl

You can configure CPAN.pm to automatically use this option too:

% cpan
cpan> o conf mbuildpl_arg '--install_base /mydir/perl'
cpan> o conf commit

Heap memory

The heap memory is the runtime data area from which the Java VM allocates memory for all class instances and arrays. The heap may be of a fixed or variable size. The garbage collector is an automatic memory management system that reclaims heap memory for objects.

• Eden Space: The pool from which memory is initially allocated for most objects.

• Survivor Space: The pool containing objects that have survived the garbage collection of the Eden space.

• Tenured Generation or Old Gen: The pool containing objects that have existed for some time in the survivor space.

Non-heap memory

Non-heap memory includes a method area shared among all threads and memory required for the internal processing or optimization for the Java VM. It stores per-class structures such as a runtime constant pool, field and method data, and the code for methods and constructors. The method area is logically part of the heap but, depending on the implementation, a Java VM may not garbage collect or compact it. Like the heap memory, the method area may be of a fixed or variable size. The memory for the method area does not need to be contiguous.

• Permanent Generation: The pool containing all the reflective data of the virtual machine itself, such as class and method objects. With Java VMs that use class data sharing, this generation is divided into read-only and read-write areas.

• Code Cache: The HotSpot Java VM also includes a code cache, containing memory that is used for compilation and storage of native code.

Using ls:

  ls -LR

from 'man ls':

   -L, --dereference
          when showing file information for a symbolic link, show informa-
          tion  for  the file the link references rather than for the link
          itself

Or, using find:

find -L .

From the find manpage:

-L     Follow symbolic links.

If you find you want to only follow a few symbolic links (like maybe just the toplevel ones you mentioned), you should look at the -H option, which only follows symlinks that you pass to it on the commandline.

Suppose I have this line of scripts in my "package.json"

"scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",

    "export_homedata": "node export.js homedata",
    "export_customdata": "node export.js customdata",
    "export_rooms": "node export.js rooms"
  },

Now to run the script "export_advertisements", I will simply go to the terminal and type

npm run export_advertisements

You are most welcome

there's another way which is not mentioned here (I didn't fully test it's performance yet), you could set array for all tables -> rows you want to delete as below

// set your tables array
$array = ['table1', 'table2', 'table3'];


// loop through each table
for($i = 0; $i < count($array); $i++){

 // get each single array
 $single_array = $array[$i];

 // build your query
 $query = "DELETE FROM $single_array WHERE id = 'id'";

 // prepare the query and get the connection
 $data = con::GetCon()->prepare($query);

 // execute the action
 $data->execute();
}

then you could redirect the user to the home page.

header('LOCATION:' . $home_page);

hope this will help someone :)

Thanks

The second clause does not need a !variable.nil? check—if evaluation reaches that point, variable.nil is guaranteed to be false (because of short-circuiting).

This should be sufficient:

variable = id if variable.nil? || variable.empty?

If you're working with Ruby on Rails, Object.blank? solves this exact problem:

An object is blank if it’s false, empty, or a whitespace string. For example, "", " ", nil, [], and {} are all blank.

sed - non greedy matching by Christoph Sieghart

The trick to get non greedy matching in sed is to match all characters excluding the one that terminates the match. I know, a no-brainer, but I wasted precious minutes on it and shell scripts should be, after all, quick and easy. So in case somebody else might need it:

Greedy matching

% echo "<b>foo</b>bar" | sed 's/<.*>//g'
bar

Non greedy matching

% echo "<b>foo</b>bar" | sed 's/<[^>]*>//g'
foobar

In my case I was miscalculating the Content-Length that I advertised in the header. I was serving Range-Requests for files and I mistakenly published the filesize in Content-Length.

I fixed the problem by setting Content-Length to the actual range that I was sending back to the browser.

So in case I am answering to a normal request I set the Content-Length to the filesize. In case I am answering to a range-request I set the Content-Length to the actualy length of the requested range.

First, you're missing some parentheses in your conditional:

if ($("#about").hasClass("opened")) {
  $("#about").animate({right: "-700px"}, 2000);
}

But you can also simplify this to:

$('#about.opened').animate(...);

If #about doesn't have the opened class, it won't animate.

If the problem is with the animation itself, we'd need to know more about your element positioning (absolute? absolute inside relative parent? does the parent have layout?)

Entity states

JPA defines the following entity states:

New (Transient)

A newly created object that hasn’t ever been associated with a Hibernate Session (a.k.a Persistence Context) and is not mapped to any database table row is considered to be in the New (Transient) state.

To become persisted we need to either explicitly call the EntityManager#persist method or make use of the transitive persistence mechanism.

Persistent (Managed)

A persistent entity has been associated with a database table row and it’s being managed by the currently running Persistence Context. Any change made to such an entity is going to be detected and propagated to the database (during the Session flush-time).

With Hibernate, we no longer have to execute INSERT/UPDATE/DELETE statements. Hibernate employs a transactional write-behind working style and changes are synchronized at the very last responsible moment, during the current Session flush-time.

Detached

Once the currently running Persistence Context is closed all the previously managed entities become detached. Successive changes will no longer be tracked and no automatic database synchronization is going to happen.

Entity state transitions

You can change the entity state using various methods defined by the EntityManager interface.

To understand the JPA entity state transitions better, consider the following diagram:

When using JPA, to reassociate a detached entity to an active EntityManager, you can use the merge operation.

When using the native Hibernate API, apart from merge, you can reattach a detached entity to an active Hibernate Sessionusing the update methods, as demonstrated by the following diagram:

Merging a detached entity

The merge is going to copy the detached entity state (source) to a managed entity instance (destination).

Consider we have persisted the following Book entity, and now the entity is detached as the EntityManager that was used to persist the entity got closed:

Book _book = doInJPA(entityManager -> {
    Book book = new Book()
    .setIsbn("978-9730228236")
    .setTitle("High-Performance Java Persistence")
    .setAuthor("Vlad Mihalcea");
 
    entityManager.persist(book);
 
    return book;
});

While the entity is in the detached state, we modify it as follows:

_book.setTitle(
    "High-Performance Java Persistence, 2nd edition"
);

Now, we want to propagate the changes to the database, so we can call the merge method:

doInJPA(entityManager -> {
    Book book = entityManager.merge(_book);
 
    LOGGER.info("Merging the Book entity");
 
    assertFalse(book == _book);
});

And Hibernate is going to execute the following SQL statements:

SELECT
    b.id,
    b.author AS author2_0_,
    b.isbn AS isbn3_0_,
    b.title AS title4_0_
FROM
    book b
WHERE
    b.id = 1
 
-- Merging the Book entity
 
UPDATE
    book
SET
    author = 'Vlad Mihalcea',
    isbn = '978-9730228236',
    title = 'High-Performance Java Persistence, 2nd edition'
WHERE
    id = 1

If the merging entity has no equivalent in the current EntityManager, a fresh entity snapshot will be fetched from the database.

Once there is a managed entity, JPA copies the state of the detached entity onto the one that is currently managed, and during the Persistence Context flush, an UPDATE will be generated if the dirty checking mechanism finds that the managed entity has changed.

So, when using merge, the detached object instance will continue to remain detached even after the merge operation.

Reattaching a detached entity

Hibernate, but not JPA supports reattaching through the update method.

A Hibernate Session can only associate one entity object for a given database row. This is because the Persistence Context acts as an in-memory cache (first level cache) and only one value (entity) is associated with a given key (entity type and database identifier).

An entity can be reattached only if there is no other JVM object (matching the same database row) already associated with the current Hibernate Session.

Considering we have persisted the Book entity and that we modified it when the Book entity was in the detached state:

Book _book = doInJPA(entityManager -> {
    Book book = new Book()
    .setIsbn("978-9730228236")
    .setTitle("High-Performance Java Persistence")
    .setAuthor("Vlad Mihalcea");
 
    entityManager.persist(book);
 
    return book;
});
      
_book.setTitle(
    "High-Performance Java Persistence, 2nd edition"
);

We can reattach the detached entity like this:

doInJPA(entityManager -> {
    Session session = entityManager.unwrap(Session.class);
 
    session.update(_book);
 
    LOGGER.info("Updating the Book entity");
});

And Hibernate will execute the following SQL statement:

-- Updating the Book entity
 
UPDATE
    book
SET
    author = 'Vlad Mihalcea',
    isbn = '978-9730228236',
    title = 'High-Performance Java Persistence, 2nd edition'
WHERE
    id = 1

The update method requires you to unwrap the EntityManager to a Hibernate Session.

Unlike merge, the provided detached entity is going to be reassociated with the current Persistence Context and an UPDATE is scheduled during flush whether the entity has modified or not.

To prevent this, you can use the @SelectBeforeUpdate Hibernate annotation which will trigger a SELECT statement that fetched loaded state which is then used by the dirty checking mechanism.

@Entity(name = "Book")
@Table(name = "book")
@SelectBeforeUpdate
public class Book {
 
    //Code omitted for brevity
}

Beware of the NonUniqueObjectException

One problem that can occur with update is if the Persistence Context already contains an entity reference with the same id and of the same type as in the following example:

Book _book = doInJPA(entityManager -> {
    Book book = new Book()
    .setIsbn("978-9730228236")
    .setTitle("High-Performance Java Persistence")
    .setAuthor("Vlad Mihalcea");
 
    Session session = entityManager.unwrap(Session.class);
    session.saveOrUpdate(book);
 
    return book;
});
 
_book.setTitle(
    "High-Performance Java Persistence, 2nd edition"
);
 
try {
    doInJPA(entityManager -> {
        Book book = entityManager.find(
            Book.class,
            _book.getId()
        );
 
        Session session = entityManager.unwrap(Session.class);
        session.saveOrUpdate(_book);
    });
} catch (NonUniqueObjectException e) {
    LOGGER.error(
        "The Persistence Context cannot hold " +
        "two representations of the same entity",
        e
    );
}

Now, when executing the test case above, Hibernate is going to throw a NonUniqueObjectException because the second EntityManager already contains a Book entity with the same identifier as the one we pass to update, and the Persistence Context cannot hold two representations of the same entity.

org.hibernate.NonUniqueObjectException:
    A different object with the same identifier value was already associated with the session : [com.vladmihalcea.book.hpjp.hibernate.pc.Book#1]

Conclusion

The merge method is to be preferred if you are using optimistic locking as it allows you to prevent lost updates.

The update is good for batch updates as it can prevent the additional SELECT statement generated by the merge operation, therefore reducing the batch update execution time.

Working with predicate for pretty long time. Here is my conclusion (SWIFT)

//Customizable! (for me was just important if at least one)
request.fetchLimit = 1


//IF IS EQUAL

//1 OBJECT
request.predicate = NSPredicate(format: "name = %@", txtFieldName.text)

//ARRAY
request.predicate = NSPredicate(format: "name = %@ AND nickName = %@", argumentArray: [name, nickname])


// IF CONTAINS

//1 OBJECT
request.predicate = NSPredicate(format: "name contains[c] %@", txtFieldName.text)

//ARRAY
request.predicate = NSPredicate(format: "name contains[c] %@ AND nickName contains[c] %@", argumentArray: [name, nickname])

I don't know if anyone is still reading this thread or not, but Jeff's solution will only get you halfway there (kinda literally). What his onMeasure will do is display half the image in half the parent. The problem is that calling super.onMeasure prior to the setMeasuredDimension will measure all the children in the view based on the original size, then just cut the view in half when the setMeasuredDimension resizes it.

Instead, you need to call setMeasuredDimension (as required for an onMeasure override) and provide a new LayoutParams for your view, then call super.onMeasure. Remember, your LayoutParams are derived from your view's parent type, not your view's type.

@Override 
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec){
   int parentWidth = MeasureSpec.getSize(widthMeasureSpec);
   int parentHeight = MeasureSpec.getSize(heightMeasureSpec);
   this.setMeasuredDimension(parentWidth/2, parentHeight);
   this.setLayoutParams(new *ParentLayoutType*.LayoutParams(parentWidth/2,parentHeight));
   super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}

I believe the only time you'll have problems with the parent LayoutParams is if the parent is an AbsoluteLayout (which is deprecated but still sometimes useful).

Determine if property is existing (but is not a falsy value):

if (typeof query !== 'undefined' && query !== null){
   doStuff();
}

Usually using

if (query){
   doStuff();
}

is sufficient. Please note that:

if (!query){
   doStuff();
}

doStuff() will execute even if query was an existing variable with falsy value (0, false, undefined or null)

Btw, there's a sexy coffeescript way of doing this:

if object?.property? then doStuff()

which compiles to:

if ((typeof object !== "undefined" && object !== null ? object.property : void 0) != null) 

{
  doStuff();
}

Tuples are immutable and not supposed to be changed - that is what the list type is for. You could replace each tuple by originalTuple + (newElement,), thus creating a new tuple. For example:

t = (1,2,3)
t = t + (1,)
print t
(1,2,3,1)

But I'd rather suggest to go with lists from the beginning, because they are faster for inserting items.

And another hint: Do not overwrite the built-in name list in your program, rather call the variable l or some other name. If you overwrite the built-in name, you can't use it anymore in the current scope.

In Java, when you write:

Object objectA = new Object();
Object objectB = objectA;

objectA and objectB are the same and point to the same reference. Changing one will change the other. So if you change the state of objectA (not its reference) objectB will reflect that change too.

However, if you write:

objectA = new Object()

Then objectB is still pointing to the first object you created (original objectA) while objectA is now pointing to a new Object.

This answer has long been answered, but I thought I would share my Decorator class which makes writing new decorators easy and compact.

from abc import ABCMeta, abstractclassmethod

class Decorator(metaclass=ABCMeta):
    """ Acts as a base class for all decorators """

    def __init__(self):
        self.method = None

    def __call__(self, method):
        self.method = method
        return self.call

    @abstractclassmethod
    def call(self, *args, **kwargs):
        return self.method(*args, **kwargs)

For one I think this makes the behavior of decorators very clear, but it also makes it easy to define new decorators very concisely. For the example listed above, you could then solve it as:

class MakeBold(Decorator):
    def call():
        return "<b>" + self.method() + "</b>"

class MakeItalic(Decorator):
    def call():
        return "<i>" + self.method() + "</i>"

@MakeBold()
@MakeItalic()
def say():
   return "Hello"

You could also use it to do more complex tasks, like for instance a decorator which automatically makes the function get applied recursively to all arguments in an iterator:

class ApplyRecursive(Decorator):
    def __init__(self, *types):
        super().__init__()
        if not len(types):
            types = (dict, list, tuple, set)
        self._types = types

    def call(self, arg):
        if dict in self._types and isinstance(arg, dict):
            return {key: self.call(value) for key, value in arg.items()}

        if set in self._types and isinstance(arg, set):
            return set(self.call(value) for value in arg)

        if tuple in self._types and isinstance(arg, tuple):
            return tuple(self.call(value) for value in arg)

        if list in self._types and isinstance(arg, list):
            return list(self.call(value) for value in arg)

        return self.method(arg)


@ApplyRecursive(tuple, set, dict)
def double(arg):
    return 2*arg

print(double(1))
print(double({'a': 1, 'b': 2}))
print(double({1, 2, 3}))
print(double((1, 2, 3, 4)))
print(double([1, 2, 3, 4, 5]))

Which prints:

2
{'a': 2, 'b': 4}
{2, 4, 6}
(2, 4, 6, 8)
[1, 2, 3, 4, 5, 1, 2, 3, 4, 5]

Notice that this example didn't include the list type in the instantiation of the decorator, so in the final print statement the method gets applied to the list itself, not the elements of the list.

The below both ways works fine.

System.out.println("The Class Name is: " + this.getClass().getName());
System.out.println("The simple Class Name is: " + this.getClass().getSimpleName());

Output as below:

The Class Name is: package.Student

The simple Class Name is: Student

DataTable dt = new DataTable();

SqlDataAdapter adapter = new SqlDataAdapter(cmd);

adapter.Fill(dt);

foreach(DataRow row in dt.Rows)
{
    TextBox1.Text = row["ImagePath"].ToString();
}

...assumes the connection is open and the command is set up properly. I also didn't check the syntax, but it should give you the idea.

                    }
                })
                 );

you can simply cast a string array to int array by:

var converted = arr.Select(int.Parse)

Launch the installer with the following command line parameters:

LAX_VM

For example: InstallXYZ.exe LAX_VM "C:\Program Files (x86)\Java\jre6\bin\java.exe"

Use the following:

$("select").attr("disabled", "disabled");

Or simply add id="pizza_kind" to <select> tag, like <select name="pizza_kind" id="pizza_kind">: jsfiddle link

The reason your code didn't work is simply because $("#pizza_kind") isn't selecting the <select> element because it does not have id="pizza_kind".

Edit: actually, a better selector is $("select[name='pizza_kind']"): jsfiddle link

You can achieve a fade effect (instead of sticking with the default slide) using css only. Add these to your stylesheet

.carousel .item {
    -webkit-transition: opacity 3s; 
    -moz-transition: opacity 3s; 
    -ms-transition: opacity 3s; 
    -o-transition: opacity 3s; 
    transition: opacity 3s;
}
.carousel .active.left {
    left:0;opacity:0;z-index:2;
}
.carousel .next {
    left:0;opacity:1;z-index:1;
}

The "official" way to configure the build.gradle file as recommended by Google is explained here.

Basically, you add a signingConfig, in where you specify the location an password of the keystore. Then, in the release build type, refer to that signing configuration.

...
android {
    ...
    defaultConfig { ... }
    signingConfigs {
        release {
            storeFile file("myreleasekey.keystore")
            storePassword "password"
            keyAlias "MyReleaseKey"
            keyPassword "password"
        }
    }
    buildTypes {
        release {
            ...
            signingConfig signingConfigs.release
        }
    }
}
...

I'll post my solution as it it subtly different from others and also took me a solid day to get right, with the assistance of the existing answers.

For a multi-module Maven project:

ROOT
|--WAR
|--LIB-1
|--LIB-2
|--TEST

Where the WAR project is the main web app, LIB 1 and 2 are additional modules the WAR depends on and TEST is where the integration tests live. TEST spins up an embedded Tomcat instance (not via Tomcat plugin) and runs WAR project and tests them via a set of JUnit tests. The WAR and LIB projects both have their own unit tests.

The result of all this is the integration and unit test coverage being separated and able to be distinguished in SonarQube.

This may not be quite the right fit to the question, but…

OFFSET clause

The OFFSET number clause enables you to skip over a number of rows and then return rows after that.

That doc link is to Postgres; I don't know if this applies to Sybase/MS SQL Server.

This is probably the most concise way of achieving your goal.All you need to do is to call Letter.getRandom() and you will get a random enum letter.

public enum Letter {
    A,
    B,
    C,
    //...

    public static Letter getRandom() {
        return values()[(int) (Math.random() * values().length)];
    }
}

I had this same problem, however in a little bit different situation. One day my application launches fine (using developer provision), then I do some minor editing to my Entitlements file, and after that it stops working. The application installed fine on my device, however every time I tried to launch it, it exited instantly (after the opening animation). (As I made edits to other files too, I did not suspect the following problem)

The problem was in the Entitlements file format, seems so that the following declarations are not the same:

Correct:

<key>get-task-allow</key>
<true/>

Incorrect:

<key>get-task-allow</key>
<true />

Altough it's an XML format, do not use spaces in the tag or the Xcode will not be able to connect to the process.

I was using developer provisioning profile all along.

Edit: Also make sure the line ending in your Entitlements file are \n (LF) instead of \r\n (CRLF). If you edit the entitlements file on Windows using CRLF line endings may cause your application to fail to launch.

this native-base there is solution:

<Button
    block
    disabled={!learnedWordsByUser.length}
    style={{ marginTop: 10 }}
    onPress={learnedWordsByUser.length && () => {
      onFlipCardsGenerateNewWords(learnedWordsByUser)
      onFlipCardsBtnPress()
    }}
>
    <Text>Let's Review</Text>
</Button>

Have a look at the limits.h file in your system it will tell the system specific limits. Or check man limits.h and go to the "Numerical Limits" section.

Additional Solution: use Restul api wrapper libraries written in Java / python / Ruby - An object oriented wrappers which aim to provide a more conventionally way of controlling a Jenkins server.

For documentation and links: Remote Access API

If your goal is simply to iterate over the range of values for read-only purposes, an alternative is to wrap both vectors around a proxy (O(1)) instead of copying them (O(n)), so they are promptly seen as a single, contiguous one.

std::vector<int> A{ 1, 2, 3, 4, 5};
std::vector<int> B{ 10, 20, 30 };

VecProxy<int> AB(A, B);  // ----> O(1)!

for (size_t i = 0; i < AB.size(); i++)
    std::cout << AB[i] << " ";  // ----> 1 2 3 4 5 10 20 30

Refer to https://stackoverflow.com/a/55838758/2379625 for more details, including the 'VecProxy' implementation as well as pros & cons.

This is because, in C#, single quotes ('') denote (or encapsulate) a single character, whereas double quotes ("") are used for a string of characters. For example:

var myChar = '=';

var myString = "==";

a=int(input('enter the lower no.'))
b=int(input('enter the higher no.'))
print("Prime numbers between",a,"and",b,"are:")
for num in range(a,b):

    if num>1:
        for i in range(2,num):
            if (num%i)==0:
                break
        else:
            print(num)

You could move the common parts to another configuration file and include from both server contexts. This should work:

server {
  listen 80;
  server_name server1.example;
  ...
  include /etc/nginx/include.d/your-common-stuff.conf;
}

server {
  listen 80;
  server_name another-one.example;
  ...
  include /etc/nginx/include.d/your-common-stuff.conf;
}

Edit: Here's an example that's actually copied from my running server. I configure my basic server settings in /etc/nginx/sites-enabled (normal stuff for nginx on Ubuntu/Debian). For example, my main server bunkus.org's configuration file is /etc/nginx/sites-enabled and it looks like this:

server {
  listen   80 default_server;
  listen   [2a01:4f8:120:3105::101:1]:80 default_server;

  include /etc/nginx/include.d/all-common;
  include /etc/nginx/include.d/bunkus.org-common;
  include /etc/nginx/include.d/bunkus.org-80;
}

server {
  listen   443 default_server;
  listen   [2a01:4f8:120:3105::101:1]:443 default_server;

  include /etc/nginx/include.d/all-common;
  include /etc/nginx/include.d/ssl-common;
  include /etc/nginx/include.d/bunkus.org-common;
  include /etc/nginx/include.d/bunkus.org-443;
}

As an example here's the /etc/nginx/include.d/all-common file that's included from both server contexts:

index index.html index.htm index.php .dirindex.php;
try_files $uri $uri/ =404;

location ~ /\.ht {
  deny all;
}

location = /favicon.ico {
  log_not_found off;
  access_log off;
}

location ~ /(README|ChangeLog)$ {
  types { }
  default_type text/plain;
}

Here is what I did to solve just by 2 ways:

1. make ID column as int type

2. if you are using autogenerate in ID dont assing value in the setter of ID. If your mapping the some then sometimes autogenetated ID is not concedered. (I dont know why)

3. try using @GeneratedValue(strategy=GenerationType.SEQUENCE) if possible

jsonObj.profile-id is a subtraction expression (i.e. jsonObj.profile - id).

To access a key that contains characters that cannot appear in an identifier, use brackets:

jsonObj["profile-id"]

In recent version, The following works fine:

    $('.selector').datetimepicker({
        maxDate: new Date()
    });

maxDate accepts a Date object as parameter.

The following found in documentation:

Multiple types supported:

• Date: A date object containing the minimum date.

• Number: A number of days from today. For example 2 represents two days from today and -1 represents yesterday.

• String: A string in the format defined by the dateFormat option, or a relative date. Relative dates must contain value and period pairs; valid periods are "y" for years, "m" for months, "w" for weeks, and "d" for days. For example, "+1m +7d" represents one month and seven days from today.

If you want to get a list of files that are only in one directory and not their sub directories and only their file names:

diff -q /dir1 /dir2 | grep /dir1 | grep -E "^Only in*" | sed -n 's/[^:]*: //p'

If you want to recursively list all the files and directories that are different with their full paths:

diff -rq /dir1 /dir2 | grep -E "^Only in /dir1*" | sed -n 's/://p' | awk '{print $3"/"$4}'

This way you can apply different commands to all the files.

For example I could remove all the files and directories that are in dir1 but not dir2:

diff -rq /dir1 /dir2 | grep -E "^Only in /dir1*" | sed -n 's/://p' | awk '{print $3"/"$4}' xargs -I {} rm -r {}

Where you already have a project in NetBeans and you wish to change the compiler (e.g. from 1.7 to 1.) then you would need to also change the Java source compiler for that project.

Right-click on the project and choose properties as outlined below:

Then check that the project has the necessary source circled below:

then check that the Java compiler is correct for the project:

I tried other answers on this question, and there are mistakes with the different browser APIs, particularly Fullscreen vs FullScreen. Here is my code that works with the major browsers (as of Q1 2019) and should continue to work as they standardize.

function fullScreenTgl() {
    let doc=document,elm=doc.documentElement;
    if      (elm.requestFullscreen      ) { (!doc.fullscreenElement   ? elm.requestFullscreen()       : doc.exitFullscreen()        ) }
    else if (elm.mozRequestFullScreen   ) { (!doc.mozFullScreen       ? elm.mozRequestFullScreen()    : doc.mozCancelFullScreen()   ) }
    else if (elm.msRequestFullscreen    ) { (!doc.msFullscreenElement ? elm.msRequestFullscreen()     : doc.msExitFullscreen()      ) }
    else if (elm.webkitRequestFullscreen) { (!doc.webkitIsFullscreen  ? elm.webkitRequestFullscreen() : doc.webkitCancelFullscreen()) }
    else                                  { console.log("Fullscreen support not detected.");                                          }
    }

Using the .mjs extension (as suggested in the accepted answer) in order to enable ECMAScript modules works. However, with Node.js v12, you can also enable this feature globally in your package.json file.

The official documentation states:

import statements of .js and extensionless files are treated as ES modules if the nearest parent package.json contains "type": "module".

{
  "type": "module",
  "main": "./src/index.js"
}

(Of course you still have to provide the flag --experimental-modules when starting your application.)

My solution to this error was that a copy and paste from another project that had a reference to @Model.Id. This particular page didn't have a model but the error line was so far off from the actual error I about never found it!

You are looking for the command scandir.

$path    = '/tmp';
$files = scandir($path);

Following code will remove . and .. from the returned array from scandir:

$files = array_diff(scandir($path), array('.', '..'));

After a few hours of messing around I eventually got something that works, partially answered in a similar issue here: How do I include a JavaScript file in another JavaScript file?

BUT there was an import that was screwing the rest of it up:

Use require in .vue files

<script>
  var mylib = require('./mylib');
  export default {
  ....

Exports in mylib

 exports.myfunc = () => {....}

Avoid import

The actual issue in my case (which I didn't think was relevant!) was that mylib.js was itself using other dependencies. The resulting error seems to have nothing to do with this, and there was no transpiling error from webpack but anyway I had:

import models from './model/models'
import axios from 'axios'

This works so long as I'm not using mylib in a .vue component. However as soon as I use mylib there, the error described in this issue arises.

I changed to:

let models = require('./model/models');
let axios = require('axios');

And all works as expected.

Inside a package if there is setup.py, then better to install it

pip install -e .

If you want a timestamp instead of just a date with sysdate, you can specify a timezone using systimestamp:

select systimestamp at time zone 'UTC' from dual

outputs: 29-AUG-17 06.51.14.781998000 PM UTC

When a script generates an html form and that form's action http POSTs back to the same form.

It's easy, you should set server http response header first. The problem is not with your front-end javascript code. You need to return this header:

Access-Control-Allow-Origin:*

or

Access-Control-Allow-Origin:your domain

In Apache config files, the code is like this:

Header set Access-Control-Allow-Origin "*"

In nodejs,the code is like this:

res.setHeader('Access-Control-Allow-Origin','*');

The "Getting Started" page is the introduction to the documentation. Most documentation will start off with installation instructions, just like Composer's do.

The page that contains information on the composer.json file is located here - under "Basic Usage", the second page.

I'd recommend reading over the documentation in full, so that you gain a better understanding of how to use Composer. I'd also recommend removing what you have and following the installation instructions provided in the documentation.

I think a lot of times when you see this code, it's from people who are in the habit of event handlers for forms, buttons, inputs, and things of that sort.

Basically, when you have something like:

<form onsubmit="return callSomeFunction();"></form>

or

<a href="#" onclick="return callSomeFunction();"></a>`

and callSomeFunction() returns true, then the form or a will submit, otherwise it won't.

Other more obvious general purposes for returning true or false as a result of a function are because they are expected to return a boolean.

underscorejs offers the very nice _.sortBy function:

_.sortBy([{a:1},{a:3},{a:2}], "a")

or you can use a custom sort function:

_.sortBy([{a:"b"},{a:"c"},{a:"a"}], function(i) {return i.a.toLowerCase()})

New to python so I don't know if this is advisable, but it works great for not re-writing boilerplate.

Your project must have an init.py so it can be loaded as a module

# Put this in your module's __init__.py
import logging.config
import sys

# I used this dictionary test, you would put:
# logging.config.fileConfig('logging.conf')
# The "" entry in loggers is the root logger, tutorials always 
# use "root" but I can't get that to work
logging.config.dictConfig({
    "version": 1,
    "formatters": {
        "default": {
            "format": "%(asctime)s %(levelname)s %(name)s %(message)s"
        },
    },
    "handlers": {
        "console": {
            "level": 'DEBUG',
            "class": "logging.StreamHandler",
            "stream": "ext://sys.stdout"
        }
    },
    "loggers": {
        "": {
            "level": "DEBUG",
            "handlers": ["console"]
        }
    }
})

def logger():
    # Get the name from the caller of this function
    return logging.getLogger(sys._getframe(1).f_globals['__name__'])

sys._getframe(1) suggestion comes from here

Then to use your logger in any other file:

from [your module name here] import logger

logger().debug("FOOOOOOOOO!!!")

Caveats:

1. You must run your files as modules, otherwise import [your module] won't work:
   • python -m [your module name].[your filename without .py]
2. The name of the logger for the entry point of your program will be __main__, but any solution using __name__ will have that issue.

But the Accepted answer Not worked for me. I think String should be In SQL, strings must be quoted. So, in my case this worked for me against the accepted answer :

 database.delete(TABLE_DAILY_NOTES, WORK_ENTRY_CLUMN_NAME + "='" + workEntry+"'", null);

Select a test (better to select a parent test class) and set a Shorten command line: option to classpath file. Then OK (or Apply, OK).

Although Xotic750's answer provides several good points and possible solutions, sometimes simple is better.

You know the array being iterated on is being mutated in the iteration itself (i.e. removing an item => index changes), thus the simplest logic is to go backwards in an old fashioned for (à la C language):

let arr = ['a', 'a', 'b', 'c', 'b', 'a', 'a'];_x000D_
_x000D_
for (let i = arr.length - 1; i >= 0; i--) {_x000D_
  if (arr[i] === 'a') {_x000D_
    arr.splice(i, 1);_x000D_
  }_x000D_
}_x000D_
_x000D_
document.body.append(arr.join());

If you really think about it, a forEach is just syntactic sugar for a for loop... So if it's not helping you, just please stop breaking your head against it.

what about this?

console.table(object)

There are a couple of ways to accomplish this using the Arrays utility class.

If the array is not sorted and is not an array of primitives:

java.util.Arrays.asList(theArray).indexOf(o)

If the array is primitives and not sorted, one should use a solution offered by one of the other answers such as Kerem Baydogan's, Andrew McKinlay's or Mishax's. The above code will compile even if theArray is primitive (possibly emitting a warning) but you'll get totally incorrect results nonetheless.

If the array is sorted, you can make use of a binary search for performance:

java.util.Arrays.binarySearch(theArray, o)

Great answers for GNU environments above and below...

But... what if you're not running on an OS? (or a PC for that matter, or you need to time your timer interrupts themselves?) Here's a solution that uses the x86 CPU timestamp counter directly... Not because this is good practice, or should be done, ever, when running under an OS...

• Caveat: Only works on x86, with frequency scaling disabled.
• Under Linux, only works on non-tickless kernels

rdtsc.c:

#include <sys/time.h>
#include <time.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>

typedef unsigned long long int64;

static __inline__ int64 getticks(void)
{
     unsigned a, d;
     asm volatile("rdtsc" : "=a" (a), "=d" (d));
     return (((int64)a) | (((int64)d) << 32));
}

int main(){

     int64 tick,tick1;
     unsigned time=0,mt;

     // mt is the divisor to give microseconds

     FILE *pf;
     int i,r,l,n=0;
     char s[100];

     // time how long it takes to get the divisors, as a test 
     tick = getticks();

     // get the divisors  - todo: for max performance this can 
     // output a new binary or library with these values hardcoded 
     // for the relevant CPU - if you use the equivalent assembler for
     // that CPU
     pf = fopen("/proc/cpuinfo","r");
     do {
      r=fscanf(pf,"%s",&s[0]);
      if (r<0) {
       n=5; break;
      } else if (n==0) {
       if (strcmp("MHz",s)==0) n=1;
      } else if (n==1) {
       if (strcmp(":",s)==0) n=2;
      } else if (n==2) {
       n=3;
      };
     } while (n<3);
     fclose(pf);

     s[9]=(char)0;
     strcpy(&s[4],&s[5]);
     mt=atoi(s);

     printf("#define mt %u // (%s Hz) hardcode this for your a CPU-specific binary ;-)\n",mt,s);

     tick1 = getticks();
     time = (unsigned)((tick1-tick)/mt);
     printf("%u ms\n",time);

     // time the duration of sleep(1) - plus overheads ;-)
     tick = getticks();

     sleep(1);

     tick1 = getticks();
     time = (unsigned)((tick1-tick)/mt);
     printf("%u ms\n",time);

     return 0;
}

compile and run with

$ gcc rdtsc.c -o rdtsc && ./rdtsc

It reads the divisor for your CPU from /proc/cpuinfo and shows how long it took to read that in microseconds, as well as how long it takes to execute sleep(1) in microseconds... Assuming the Mhz rating in /proc/cpuinfo always contains 3 decimal places :-o

(Look at the last edit in this answer if you need to use .on() with elements populated with JavaScript)

Use this for elements that are not populated using JavaScript:

$(".selector").on("mouseover", function () {
    //stuff to do on mouseover
});

.hover() has it's own handler: http://api.jquery.com/hover/

If you want to do multiple things, chain them in the .on() handler like so:

$(".selector").on({
    mouseenter: function () {
        //stuff to do on mouse enter
    },
    mouseleave: function () {
        //stuff to do on mouse leave
    }
});

According to the answers provided below you can use hover with .on(), but:

Although strongly discouraged for new code, you may see the pseudo-event-name "hover" used as a shorthand for the string "mouseenter mouseleave". It attaches a single event handler for those two events, and the handler must examine event.type to determine whether the event is mouseenter or mouseleave. Do not confuse the "hover" pseudo-event-name with the .hover() method, which accepts one or two functions.

Also, there are no performance advantages to using it and it's more bulky than just using mouseenter or mouseleave. The answer I provided requires less code and is the proper way to achieve something like this.

EDIT

It's been a while since this question was answered and it seems to have gained some traction. The above code still stands, but I did want to add something to my original answer.

While I prefer using mouseenter and mouseleave (helps me understand whats going on in the code) with .on() it is just the same as writing the following with hover()

$(".selector").hover(function () {
    //stuff to do on mouse enter
}, 
function () {
    //stuff to do on mouse leave
});

Since the original question did ask how they could properly use on() with hover(), I thought I would correct the usage of on() and didn't find it necessary to add the hover() code at the time.

EDIT DECEMBER 11, 2012

Some new answers provided below detail how .on() should work if the div in question is populated using JavaScript. For example, let's say you populate a div using jQuery's .load() event, like so:

(function ($) {
    //append div to document body
    $('<div class="selector">Test</div>').appendTo(document.body);
}(jQuery));

The above code for .on() would not stand. Instead, you should modify your code slightly, like this:

$(document).on({
    mouseenter: function () {
        //stuff to do on mouse enter
    },
    mouseleave: function () {
        //stuff to do on mouse leave
    }
}, ".selector"); //pass the element as an argument to .on

This code will work for an element populated with JavaScript after a .load() event has happened. Just change your argument to the appropriate selector.

/* eslint no-restricted-globals:0 */

is another alternate approach

Registering assmblies into the GAC does not then place a reference to the assembly in the add references dialog. You still need to reference the assembly by path for your project, the main difference being you do not need to use the copy local option, your app will find it at runtime.

In this particular case, you just need to reference your assembly by path (browse) or if you really want to have it in the add reference dialog there is a registry setting where you can add additional paths.

Note, if you ship your app to someone who does not have this assembly installed you will need to ship it, and in this case you really need to use the SharedManagementObjects.msi redistributable.

You shouldn't measure time in interval function. Instead just save time when timer was started and measure difference when timer was stopped/paused. Use setInterval only to update displayed value. So there is no need to pause timer and you will get best possible accuracy in this way.

I faced the same problem,but after hours of efforts i find the solution.It can be without using any external plugin:)

applicantListToExport: function (query, callback) {
  this
   .find(query).select({'advtId': 0})
   .populate({
      path: 'influId',
      model: 'influencer',
      select: { '_id': 1,'user':1},
      populate: {
        path: 'userid',
        model: 'User'
      }
   })
 .populate('campaignId',{'campaignTitle':1})
 .exec(callback);
}

Every response here is using vImageBoxConvolve_ARGB8888 this function is really, really slow, that is fine, if the performance is not a high priority requirement, but if you are using this for transitioning between two View Controllers (for example) this approach means times over 1 second or maybe more, that is very bad to the user experience of your application.

If you prefer leave all this image processing to the GPU (And you should) you can get a much better effect and also awesome times rounding 50ms (supposing that you have a time of 1 second in the first approach), so, lets do it.

First download the GPUImage Framework (BSD Licensed) here.

Next, Add the following classes (.m and .h) from the GPUImage (I'm not sure that these are the minimum needed for the blur effect only)

• GPUImage.h
• GPUImageAlphaBlendFilter
• GPUImageFilter
• GPUImageFilterGroup
• GPUImageGaussianBlurPositionFilter
• GPUImageGaussianSelectiveBlurFilter
• GPUImageLuminanceRangeFilter
• GPUImageOutput
• GPUImageTwoInputFilter
• GLProgram
• GPUImageBoxBlurFilter
• GPUImageGaussianBlurFilter
• GPUImageiOSBlurFilter
• GPUImageSaturationFilter
• GPUImageSolidColorGenerator
• GPUImageTwoPassFilter

• GPUImageTwoPassTextureSamplingFilter

• iOS/GPUImage-Prefix.pch

• iOS/GPUImageContext
• iOS/GPUImageMovieWriter
• iOS/GPUImagePicture
• iOS/GPUImageView

Next, create a category on UIImage, that will add a blur effect to an existing UIImage:

#import "UIImage+Utils.h"

#import "GPUImagePicture.h"
#import "GPUImageSolidColorGenerator.h"
#import "GPUImageAlphaBlendFilter.h"
#import "GPUImageBoxBlurFilter.h"

@implementation UIImage (Utils)

- (UIImage*) GPUBlurredImage
{
    GPUImagePicture *source =[[GPUImagePicture alloc] initWithImage:self];

    CGSize size = CGSizeMake(self.size.width * self.scale, self.size.height * self.scale);

    GPUImageBoxBlurFilter *blur = [[GPUImageBoxBlurFilter alloc] init];
    [blur setBlurRadiusInPixels:4.0f];
    [blur setBlurPasses:2.0f];
    [blur forceProcessingAtSize:size];
    [source addTarget:blur];

    GPUImageSolidColorGenerator * white = [[GPUImageSolidColorGenerator alloc] init];

    [white setColorRed:1.0f green:1.0f blue:1.0f alpha:0.1f];
    [white forceProcessingAtSize:size];

    GPUImageAlphaBlendFilter * blend = [[GPUImageAlphaBlendFilter alloc] init];
    blend.mix = 0.9f;

    [blur addTarget:blend];
    [white addTarget:blend];

    [blend forceProcessingAtSize:size];
    [source processImage];

    return [blend imageFromCurrentlyProcessedOutput];
}

@end

And last, add the following frameworks to your project:

AVFoundation CoreMedia CoreVideo OpenGLES

Yeah, got fun with this much faster approach ;)

You can use mkdir:

$ man 2 mkdir

#include <sys/stat.h>
#include <sys/types.h>

int result = mkdir("/home/me/test.txt", 0777);

I wasn't happy with any of these approaches, so I came up with a Flexlist class that allows for flexible indexing, either by integer, slice or index-list:

class Flexlist(list):
    def __getitem__(self, keys):
        if isinstance(keys, (int, slice)): return list.__getitem__(self, keys)
        return [self[k] for k in keys]

Which, for your example, you would use as:

L = Flexlist(['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h'])
Idx = [0, 3, 7]
T = L[ Idx ]

print(T)  # ['a', 'd', 'h']

In my case:

PHImageRequestOptions *requestOptions = [PHImageRequestOptions new];

You mean that want to get status codes?

VolleyError has a member variable type of NetworkResponse and it is public.

You can access error.networkResponse.statusCode for http error code.

I hope it is helpful for you.

You could use getdate() in a default as this SO question's accepted answer shows. This way you don't provide the date, you just insert the rest and that date is the default value for the column.

You could also provide it in the values list of your insert and do it manually if you wish.

No, if you are debugging an app without other users use the Build > Build APK(s) menu in Android Studio or execute it in your device/emulator them the debug release apk will install automatically. If you are debugging an app with others use Build > Generate Signed APK... menu. If you want to publish the beta version use the Google Play Store. Your APK(s) will be in app\build\outputs\apk\debug and app\release folders.

This will add a path to your Python process / instance (i.e. the running executable). The path will not be modified for any other Python processes. Another running Python program will not have its path modified, and if you exit your program and run again the path will not include what you added before. What are you are doing is generally correct.

set.py:

import sys
sys.path.append("/tmp/TEST")

loop.py

import sys
import time
while True:
  print sys.path
  time.sleep(1)

run: python loop.py &

This will run loop.py, connected to your STDOUT, and it will continue to run in the background. You can then run python set.py. Each has a different set of environment variables. Observe that the output from loop.py does not change because set.py does not change loop.py's environment.

A note on importing

Python imports are dynamic, like the rest of the language. There is no static linking going on. The import is an executable line, just like sys.path.append....

When you want to throw away a specific number of characters from the input stream manually.

A very common use case is using this to safely ignore newline characters since cin will sometimes leave newline characters that you will have to go over to get to the next line of input.

Long story short it gives you flexibility when handling stream input.

In Java 8, you can read a whole file, simply with:

public String read(String file) throws IOException {
  return new String(Files.readAllBytes(Paths.get(file)));
}

or if its a Resource:

public String read(String file) throws IOException {
  URL url = Resources.getResource(file);
  return Resources.toString(url, Charsets.UTF_8);
}

linq many ways to implement single simple query on collections, just we write joins in sql, a filter can be applied first or last depending on the need and necessity.

Here is an example where we can find an element with a id in a collection. To add more on this, methods First, FirstOrDefault, would ideally return same when a collection has at least one record. If, however, a collection is okay to be empty. then First will return an exception but FirstOrDefault will return null or default. For instance, int will return 0. Thus usage of such is although said to be personal preference, but its better to use FirstOrDefault to avoid exception handling.

EDIT 3: Seems that the extension no longer exists... Normally to get around CORS these days I set up another version of Chrome with a separate directory or I use Firefox with https://addons.mozilla.org/en-US/firefox/addon/cors-everywhere/ instead.

EDIT 2: I can no longer get this to work consistently.

EDIT: I tried using the just the other day for another project and it stopped working. Uninstalling and reinstalling the extension fixed it (to reset the defaults).

Original Answer:

I didn't want to restart Chrome and disable my web security (because I was browsing while developing) and stumbled onto this Chrome extension.

Chrome Web Store Allow-Control-Allow-Origin: *
(https://chrome.google.com/webstore/detail/allow-control-allow-origi/nlfbmbojpeacfghkpbjhddihlkkiljbi?hl=en)

Basically it's a little toggle switch to toggle on and off the Allow-Access-Origin-Control check. Works perfectly for me for what I'm doing.

Instead of configuring Tomcat to redirect requests, use Apache as a frontend with the Apache Tomcat connector so that Apache is only serving static content, while asking tomcat for dynamic content.

Using the JKmount directive (or others) you could specify exactly which requests are sent to Tomcat.

Requests for static content, such as images, would be served directly by Apache, using a standard virtual host configuration, while other requests, defined in the JKMount directive will be sent to Tomcat workers.

I think this implementation would give you the most flexibility and control on the overall application.

How about this one:

select 
    from_unixtime(unix_timestamp(timestamp) - unix_timestamp(timestamp) mod 300) as ts,  
    sum(value)
from group_interval 
group by ts 
order by ts
;

Using constants allows to combine multiple fields for verification:

dplyr >= 1.0.0 using across

sum up each row using rowSums (rowwise works for any aggreation, but is slower)

df %>%
   replace(is.na(.), 0) %>%
   mutate(sum = rowSums(across(where(is.numeric))))

sum down each column

df %>%
   summarise(across(everything(), ~ sum(., is.na(.), 0)))

dplyr < 1.0.0

sum up each row

df %>%
   replace(is.na(.), 0) %>%
   mutate(sum = rowSums(.[1:5]))

sum down each column using superseeded summarise_all:

df %>%

   summarise_all(funs(sum))

I had such problem. In my case problem was in data - my column 'information' contained 1 unique value and it caused error

UPDATE: to correct work 'pivot' pairs (id_user,information) cannot have duplicates

It works:

'value': [1, '01.01.00', '01.02.00', 2, '01.03.00', 3, '01.04.00']})
df2.pivot(index='id_user', columns='information', values='value')

it doesn't work:

df2 = pd.DataFrame({'id_user':[1,2,3,4,4,5,5], 
'information':['phone','phone','phone','phone','phone','phone','phone'], 
'value': [1, '01.01.00', '01.02.00', 2, '01.03.00', 3, '01.04.00']})

        }


     }

As stated by a few others, this is a linking error. The section of code where this function is being called doesn't know what this function is. It either needs to be declared in a header file an defined in its own source file, or defined or declared in the same source file, above where it's being called.

Edit: In older versions of C, C89/C90, function declarations weren't actually required. So, you could just add the definition anywhere in the file in which you're using the function, even after the call and the compiler would infer the declaration. For example,

int main()
{
  int a = func();
}

int func()
{
   return 1;
}

However, this isn't good practice today and most languages, C++ for example, won't allow it. One way to get away with defining the function in the same source file in which you're using it, is to declare it at the beginning of the file. So, the previous example would look like this instead.

int func();

int main()
{
   int a = func();
}

int func()
{
  return 1;
}

Instant.ofEpochSecond( 1_280_512_800L )

2010-07-30T18:00:00Z

java.time

The new java.time framework built into Java 8 and later is the successor to Joda-Time.

These new classes include a handy factory method to convert a count of whole seconds from epoch. You get an Instant, a moment on the timeline in UTC with up to nanoseconds resolution.

Instant instant = Instant.ofEpochSecond( 1_280_512_800L );

instant.toString(): 2010-07-30T18:00:00Z

See that code run live at IdeOne.com.

Asia/Kabul or Asia/Tehran time zones ?

You reported getting a time-of-day value of 22:30 instead of the 18:00 seen here. I suspect your PHP utility is implicitly applying a default time zone to adjust from UTC. My value here is UTC, signified by the Z (short for Zulu, means UTC). Any chance your machine OS or PHP is set to Asia/Kabul or Asia/Tehran time zones? I suppose so as you report IRST in your output which apparently means Iran time. Currently in 2017 those are the only zones operating with a summer time that is four and a half hours ahead of UTC.

Specify a proper time zone name in the format of continent/region, such as America/Montreal, Africa/Casablanca, or Pacific/Auckland. Never use the 3-4 letter abbreviation such as EST or IST or IRST as they are not true time zones, not standardized, and not even unique(!).

If you want to see your moment through the lens of a particular region's time zone, apply a ZoneId to get a ZonedDateTime. Still the same simultaneous moment, but seen as a different wall-clock time.

ZoneId z = ZoneId.of( "Asia/Tehran" ) ;
ZonedDateTime zdt = instant.atZone( z );  // Same moment, same point on timeline, but seen as different wall-clock time.

2010-07-30T22:30+04:30[Asia/Tehran]

Converting from java.time to legacy classes

You should stick with the new java.time classes. But you can convert to old if required.

java.util.Date date = java.util.Date.from( instant );

Joda-Time

UPDATE: The Joda-Time project is now in maintenance mode, with the team advising migration to the java.time classes.

FYI, the constructor for a Joda-Time DateTime is similar: Multiply by a thousand to produce a long (not an int!).

DateTime dateTime = new DateTime( ( 1_280_512_800L * 1000_L ), DateTimeZone.forID( "Europe/Paris" ) );

Best to avoid the notoriously troublesome java.util.Date and .Calendar classes. But if you must use a Date, you can convert from Joda-Time.

java.util.Date date = dateTime.toDate();

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android (<26), the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

The solution for me was to add :

<system.webServer>
    <modules runAllManagedModulesForAllRequests="true">
      <remove name="WebDAVModule"/>
    </modules>
</system.webServer>

To my web.config

Keyboard shortcut:

(defun reload-init-file ()
  (interactive)
  (load-file user-init-file))

(global-set-key (kbd "C-c C-l") 'reload-init-file)    ; Reload .emacs file

Using Java 8 this can be performed in various ways using streams, parallel streams and removeIf method:

List<String> stringList = new ArrayList<>(Arrays.asList(null, "A", "B", null, "C", null));
List<String> listWithoutNulls1 = stringList.stream()
                .filter(Objects::nonNull)
                .collect(Collectors.toList()); //[A,B,C]
List<String> listWithoutNulls2 = stringList.parallelStream()
                .filter(Objects::nonNull)
                .collect(Collectors.toList()); //[A,B,C]
stringList.removeIf(Objects::isNull); //[A,B,C]

The parallel stream will make use of available processors and will speed up the process for reasonable sized lists. It is always advisable to benchmark before using streams.

There is no cross browser way of doing it, for security reasons. What people usually do is overlay the input file over something else and set it's visibility to hidden so it gets triggered on it's own. More info here.

Lets look at ways to reference the image.

Back a directory

../

Folder in a directory:

 foldername/

File in a directory

 imagename.jpg

Now, lets combine them with the addresses you specified.

 /Resources/views/Default/index.html
 /Resources/public/images/iwojimaflag.jpg

The first common directory referenced from the html file is three back:

 ../../../

It is in within two folders in that:

 ../../../public/images/

And you've reached the image:

 ../../../public/images/iwojimaflag.jpg

Note: This is assuming you are accessing a page at domain.com/Resources/views/Default/index.html as you specified in your comment.

on my pc I had the same problem and it was because in properties -> security I didn't have the ownership of the file...

The specific format is:

git commit --author="John Doe <[email protected]>" -m "Impersonation is evil." 

This is what worked for me

    function showErrorMessage(xhr, status, error) {
        if (xhr.responseText != "") {

            var jsonResponseText = $.parseJSON(xhr.responseText);
            var jsonResponseStatus = '';
            var message = '';
            $.each(jsonResponseText, function(name, val) {
                if (name == "ResponseStatus") {
                    jsonResponseStatus = $.parseJSON(JSON.stringify(val));
                     $.each(jsonResponseStatus, function(name2, val2) {
                         if (name2 == "Message") {
                             message = val2;
                         }
                     });
                }
            });

            alert(message);
        }
    }

number_string = '0, 0, 0, 11, 0, 0, 0, 0, 0, 19, 0, 9, 0, 0, 0, 0, 0, 0, 11'

number_string = number_string.split(',')

number_string = [int(i) for i in number_string]

this seems to work on our site, using your ideas and a little math based upon the left edge of wrapper div. It seems redundant to go left 50% then take out 50% extra margin, but it seems to work.

div.ImgWrapper {
    width: 160px;
    height: 160px
    overflow: hidden;
    text-align: center;
}

img.CropCenter {
    left: 50%;
    margin-left: -100%;
    position: relative;
    width: auto !important;
    height: 160px !important;
}

<div class="ImgWrapper">
<a href="#"><img class="CropCenter" src="img.png"></a>
</div>

While they are not the same thing, in one sense DISTINCT implies a GROUP BY, because every DISTINCT could be re-written using GROUP BY instead. With that in mind, it doesn't make sense to order by something that's not in the aggregate group.

For example, if you have a table like this:

col1  col2
----  ----
 1     1
 1     2
 2     1
 2     2
 2     3
 3     1

and then try to query it like this:

SELECT DISTINCT col1 FROM [table] WHERE col2 > 2 ORDER BY col1, col2

That would make no sense, because there could end up being multiple col2 values per row. Which one should it use for the order? Of course, in this query you know the results wouldn't be that way, but the database server can't know that in advance.

Now, your case is a little different. You included all the columns from the order by clause in the select clause, and therefore it would seem at first glance that they were all grouped. However, some of those columns were included in a calculated field. When you do that in combination with distinct, the distinct directive can only be applied to the final results of the calculation: it doesn't know anything about the source of the calculation any more.

This means the server doesn't really know it can count on those columns any more. It knows that they were used, but it doesn't know if the calculation operation might cause an effect similar to my first simple example above.

So now you need to do something else to tell the server that the columns are okay to use for ordering. There are several ways to do that, but this approach should work okay:

SELECT rsc.RadioServiceCodeId,
            rsc.RadioServiceCode + ' - ' + rsc.RadioService as RadioService
FROM sbi_l_radioservicecodes rsc
INNER JOIN sbi_l_radioservicecodegroups rscg 
    ON rsc.radioservicecodeid = rscg.radioservicecodeid
WHERE rscg.radioservicegroupid IN 
    (SELECT val FROM dbo.fnParseArray(@RadioServiceGroup,','))
    OR @RadioServiceGroup IS NULL  
GROUP BY rsc.RadioServiceCode,rsc.RadioServiceCodeId,rsc.RadioService
ORDER BY rsc.RadioServiceCode,rsc.RadioServiceCodeId,rsc.RadioService

The PHP documentation for time() shows an example of how you can get a date one week out. You can modify this to instead go into a loop that iterates a maximum of 7 times, get the timestamp each time, get the corresponding date, and from that get the day of the week.

tomcat.sh helps you know this easily.

tomcat.sh usage doc says:

no argument: display the process-id of the tomcat, if it's running, otherwise do nothing

So, run command on your command prompt and check for pid:

$ tomcat.sh

<dependency>
    <groupId>org.postgresql</groupId>
    <artifactId>postgresql</artifactId>
    <scope>runtime</scope>
</dependency>

you can find it by running the following command

mysql --help

it will give you the mysql installed directory and all commands for mysql.

a very common try_files line which can be applied on your condition is

location / {
    try_files $uri $uri/ /test/index.html;
}

you probably understand the first part, location / matches all locations, unless it's matched by a more specific location, like location /test for example

The second part ( the try_files ) means when you receive a URI that's matched by this block try $uri first, for example http://example.com/images/image.jpg nginx will try to check if there's a file inside /images called image.jpg if found it will serve it first.

Second condition is $uri/ which means if you didn't find the first condition $uri try the URI as a directory, for example http://example.com/images/, ngixn will first check if a file called images exists then it wont find it, then goes to second check $uri/ and see if there's a directory called images exists then it will try serving it.

Side note: if you don't have autoindex on you'll probably get a 403 forbidden error, because directory listing is forbidden by default.

EDIT: I forgot to mention that if you have index defined, nginx will try to check if the index exists inside this folder before trying directory listing.

Third condition /test/index.html is considered a fall back option, (you need to use at least 2 options, one and a fall back), you can use as much as you can (never read of a constriction before), nginx will look for the file index.html inside the folder test and serve it if it exists.

If the third condition fails too, then nginx will serve the 404 error page.

Also there's something called named locations, like this

location @error {
}

You can call it with try_files like this

try_files $uri $uri/ @error;

TIP: If you only have 1 condition you want to serve, like for example inside folder images you only want to either serve the image or go to 404 error, you can write a line like this

location /images {
    try_files $uri =404;
}

which means either serve the file or serve a 404 error, you can't use only $uri by it self without =404 because you need to have a fallback option.
You can also choose which ever error code you want, like for example:

location /images {
    try_files $uri =403;
}

This will show a forbidden error if the image doesn't exist, or if you use 500 it will show server error, etc ..

The answers here are outdated, as of today Sep 30 2016. Gmail is currently rolling out support for the style tag in the head, as well as media queries. If Gmail is your only concern, you're safe to use classes like a modern developer!

For reference, you can check the official gmail CSS docs.

As a side note, Gmail was the only major client that didn't support style (reference, until they update anyway). That means you can almost safely stop putting styles inline. Some of the more obscure clients may still need them.

To compare each item with the next one in an iterator without instantiating a list:

import itertools
it = (x for x in range(10))
data1, data2 = itertools.tee(it)
data2.next()
for a, b in itertools.izip(data1, data2):
  print a, b

These error meassages

1.For the Visual Studio compiler: error C2065: 'printf' : undeclared identifier
2.For the GCC compiler: `printf' undeclared (first use in this function)

mean that you use name printf but the compiler does not see where the name was declared and accordingly does not know what it means.

Any name used in a program shall be declared before its using. The compiler has to know what the name denotes.

In this particular case the compiler does not see the declaration of name printf . As we know (but not the compiler) it is the name of standard C function declared in header <stdio.h> in C or in header <cstdio> in C++ and placed in standard (std::) and global (::) (not necessarily) name spaces.

So before using this function we have to provide its name declaration to the compiler by including corresponding headers.

For example C:

#include <stdio.h>

int main( void )
{
   printf( "Hello World\n" );
}

C++:

#include <cstdio>

int main()
{
   std::printf( "Hello World\n" );
   // or printf( "Hello World\n" );
   // or ::printf( "Hello World\n" );
}

Sometimes the reason of such an error is a simple typo. For example let's assume that you defined function PrintHello

void PrintHello()
{
    std::printf( "Hello World\n" );
}

but in main you made a typo and instead of PrintHello you typed printHello with lower case letter 'p'.

#include <cstdio>

void PrintHello()
{
    std::printf( "Hello World\n" );
}

int main()
{
   printHello();
}

In this case the compiler will issue such an error because it does not see the declaration of name printHello. PrintHello and printHello are two different names one of which was declared and other was not declared but used in the body of main

First, align-items is for items in a single row. So for a single row of elements on main axis, align-items will align these items respective of each other and it will start with fresh perspective from the next row.

Now, align-content doesn't interfere with items in a row but with rows itself. Hence, align-content will try to align rows with respect to each other and flex container.

                    .GetMember(value.ToString())
                    .First()
                    .GetCustomAttributes(false)
                    .OfType<T>()
                    .LastOrDefault();
    }
}

And this is the extension method for strings for converting to title case:

    /// </summary>
    /// <param name="s"></param>
    /// <returns></returns>
    public static string ToSpacedTitleCase(this string s)

        CultureInfo cultureInfo = Thread.CurrentThread.CurrentCulture;
        TextInfo textInfo = cultureInfo.TextInfo;
        return textInfo
           .ToTitleCase(Regex.Replace(s, 
                        "([a-z](?=[A-Z0-9])|[A-Z](?=[A-Z][a-z]))", "$1 "));
    }

I'm a MacOS user.

I solved it by uninstalling Android Studio and reinstalling it again.

If you want to try this link helped me a lot.

Uninstall Android Studio MacOS (terminal)

using this we can add two array with out any loop.

I believe if you have 2 arrays of the same type that you want to combine into one of array, there's a very simple way to do that.

Here's the code:

String[] TextFils = Directory.GetFiles(basePath, "*.txt");
String[] ExcelFils = Directory.GetFiles(basePath, "*.xls");
String[] finalArray = TextFils.Concat(ExcelFils).ToArray();

or

String[] Fils = Directory.GetFiles(basePath, "*.txt");
String[] ExcelFils = Directory.GetFiles(basePath, "*.xls");
Fils = Fils.Concat(ExcelFils).ToArray();

You dont have to

RUN mkdir -p /usr/src/app

This will be created automatically when you specifiy your WORKDIR

FROM node:latest
WORKDIR /usr/src/app
COPY package.json .
RUN npm install
COPY . ./
EXPOSE 3000
CMD [ “npm”, “start” ] 

I have used Solr, in my project and it is the best so far.

I believe IsEmpty is just method that takes return value of Cell and checks if its Empty so: IsEmpty(.Cell(i,1)) does ->

return .Cell(i,1) <> Empty

just for additional info, If your apps is automatically run on emulator, right click on the project, Run As -> Run Configuration, then on the Run Configuration choose on the Manual. after that, if you run your apps you will be prompted to chose where you want to run your apps, there will be listed all the available device and emulator.

No, how you are doing it is correct.

You can easily install it using Anaconda. At first install Anaconda or Miniconda on you system (download from here) and then install the pyqt as follow:

conda install pyqt

It works for both version of python (2 and 3).

The 500 code would normally indicate an error on the server, not anything with your code. Some thoughts

• Talk to the server developer for more info. You can't get more info directly.
• Verify your arguments into the call (values). Look for anything you might think could cause a problem for the server process. The process should not die and should return you a better code, but bugs happen there also.
• Could be intermittent, like if the server database goes down. May be worth trying at another time.

One probably crazy idea or patch :

Just toggle the flag of network reachability

This is code which I use to toggle my flag runtime by triggering 'Simulator Memory Warning' and its COMPLETELY SAFE, just make sure code should be in DEBUG Mode only

- (void)applicationDidReceiveMemoryWarning:(UIApplication *)application 
{
#ifdef DEBUG
    isInternetAvailable = !isInternetAvailable;
#endif 
}

For Intellij Idea sometime localhost.log file generated at different location. For e.g. you can find it at homedirectory\ .IntelliJIdea14\system\tomcat.

IF you are using spring then start ur server in debug mode and put debug point in catch block of org.springframework.context.support.AbstractApplicationContext's refresh() method. If bean creation fails you would be able to see the exception.

You should absolutely use isEmpty(). Computing the size() of an arbitrary list could be expensive. Even validating whether it has any elements can be expensive, of course, but there's no optimization for size() which can't also make isEmpty() faster, whereas the reverse is not the case.

For example, suppose you had a linked list structure which didn't cache the size (whereas LinkedList<E> does). Then size() would become an O(N) operation, whereas isEmpty() would still be O(1).

Additionally of course, using isEmpty() states what you're actually interested in more clearly.

i've been researching for that too but unfortunately the facebook device auth is still on experimental and they didn't give new keys (partner) to use the device auth.

You can find the working example here: http://oauth-device-demo.appspot.com/ Just look at the website source and you can have the appID that works with it.

The other one is twitter PIN oauth it's working and publicly available (i'm using it) https://dev.twitter.com/docs/auth/pin-based-authorization

    // A generic test function that can be configured 
    // with an arbitrary delay and to either resolve or reject
    const test = (delay, resolveSuccessfully) => new Promise((resolve, reject) => setTimeout(() => {
        console.log(`Done ${ delay }`);
        resolveSuccessfully ? resolve(`Resolved ${ delay }`) : reject(`Reject ${ delay }`)
    }, delay));

    // Our async handler function
    const handler = async () => {
        // Promise 1 runs first, but resolves last
        const p1 = test(10000, true);
        // Promise 2 run second, and also resolves
        const p2 = test(5000, true);
        // Promise 3 runs last, but completes first (with a rejection) 
        // Note the catch to trap the error immediately
        const p3 = test(1000, false).catch(e => console.log(e));
        // Await all in parallel
        const r = await Promise.all([p1, p2, p3]);
        // Display the results
        console.log(r);
    };

    // Run the handler
    handler();
    /*
    Done 1000
    Reject 1000
    Done 5000
    Done 10000
    */

Whilst setting p1, p2 and p3 is not strictly running them in parallel, they do not hold up any execution and you can trap contextual errors with a catch.

As other's have mentioned, PHP's cURL functions will allow you to perform advanced HTTP requests. You can also use file_get_contents to access REST APIs:

$payload = file_get_contents('http://api.someservice.com/SomeMethod?param=value');

Starting with PHP 5 you can also create a stream context which will allow you to change headers or post data to the service.

The first part (setting the output size explictly) isn't too hard:

import matplotlib.pyplot as plt
list1 = [3,4,5,6,9,12]
list2 = [8,12,14,15,17,20]
fig = plt.figure(figsize=(4,3))
ax = fig.add_subplot(111)
ax.plot(list1, list2)
fig.savefig('fig1.png', dpi = 300)
fig.close()

But after a quick google search on matplotlib + tiff, I'm not convinced that matplotlib can make tiff plots. There is some mention of the GDK backend being able to do it.

One option would be to convert the output with a tool like imagemagick's convert.

(Another option is to wait around here until a real matplotlib expert shows up and proves me wrong ;-)

Look at the fiddle here for a quick answer

data-ng-attr-title="{{d.age > 5 ? 'My age is greater than threshold': ''}}"

Displays Title over elements conditionally using Angular JS

To get the value of my drop down box on page load, I use

document.addEventListener('DOMContentLoaded',fnName);

Hope this helps some one.

As the whole thing is mixing up let's look at it function and code to simulate what it means consicely

The only way to get a row is via primary key

getRow(pk: PrimaryKey): Row

Primary key data structure can be this:

// If you decide your primary key is just the partition key.
class PrimaryKey(partitionKey: String)

// and in thids case
getRow(somePartitionKey): Row

However you can decide your primary key is partition key + sort key in this case:

// if you decide your primary key is partition key + sort key
class PrimaryKey(partitionKey: String, sortKey: String)

getRow(partitionKey, sortKey): Row
getMultipleRows(partitionKey): Row[]

So the bottom line:

1. Decided that your primary key is partition key only? get single row by partition key.

2. Decided that your primary key is partition key + sort key? 2.1 Get single row by (partition key, sort key) or get range of rows by (partition key)

In either way you get a single row by primary key the only question is if you defined that primary key to be partition key only or partition key + sort key

Building blocks are:

1. Table
2. Item
3. KV Attribute.

Think of Item as a row and of KV Attribute as cells in that row.

1. You can get an item (a row) by primary key.
2. You can get multiple items (multiple rows) by specifying (HashKey, RangeKeyQuery)

You can do (2) only if you decided that your PK is composed of (HashKey, SortKey).

More visually as its complex, the way I see it:

+----------------------------------------------------------------------------------+

So what is happening above. Notice the following observations. As we said our data belongs to (Table, Item, KVAttribute). Then Every Item has a primary key. Now the way you compose that primary key is meaningful into how you can access the data.

If you decide that your PrimaryKey is simply a hash key then great you can get a single item out of it. If you decide however that your primary key is hashKey + SortKey then you could also do a range query on your primary key because you will get your items by (HashKey + SomeRangeFunction(on range key)). So you can get multiple items with your primary key query.

Note: I did not refer to secondary indexes.

Pekka has the correct answer (hence my making this answer a Community Wiki): Use src, not href, to specify the file.

Regarding:

When i try it this way:

<script type="text/javascript">
    document.write('<script type="text/javascript" src="datetimepicker_css.js"></script>');
</script>

the first tag in the document.write function closes
what is the correct way to do this?

You don't want or need document.write for this, but just in case you ever do need to put the characters </script> inside a script tag for some other reason: You do that by ensuring that the HTML parser (which doesn't understand JavaScript) doesn't see a literal </script>. There are a couple of ways of doing that. One way is to escape the / even though you don't need to:

<script type='text/javascript'>
alert("<\/script>"); // Works, HTML parser doesn't see this as a closing script tag
//      ^--- note the seemingly-unnecessary backslash
</script>

Or if you're feeling more paranoid:

<script type='text/javascript'>
alert("</scr" + "ipt>"); // Works, HTML parser doesn't see this as a closing script tag
</script>

...since in each case, JavaScript sees the string as </script> but the HTML parser doesn't.

For anyone trying to use jQuery.active with JSONP requests (like I was) you'll need enable it with this:

jQuery.ajaxPrefilter(function( options ) {
    options.global = true;
});

Keep in mind that you'll need a timeout on your JSONP request to catch failures.

Overall, the conventions are “think like you're just delivering web pages”.

For a PUT, I'd return the same view that you'd get if you did a GET immediately after; that would result in a 200 (well, assuming the rendering succeeds of course). For a POST, I'd do a redirect to the resource created (assuming you're doing a creation operation; if not, just return the results); the code for a successful create is a 201, which is really the only HTTP code for a redirect that isn't in the 300 range.

I've never been happy about what a DELETE should return (my code currently produces an HTTP 204 and an empty body in this case).

The error is:

Can not deserialize instance of java.lang.String out of START_ARRAY token at [Source: line: 1, column: 1095] (through reference chain: JsonGen["platforms"])

In JSON, platforms look like this:

"platforms": [
    {
        "platform": "iphone"
    },
    {
        "platform": "ipad"
    },
    {
        "platform": "android_phone"
    },
    {
        "platform": "android_tablet"
    }
]

So try change your pojo to something like this:

private List platforms;

public List getPlatforms(){
    return this.platforms;
}

public void setPlatforms(List platforms){
    this.platforms = platforms;
}

EDIT: you will need change mobile_networks too. Will look like this:

private List mobile_networks;

public List getMobile_networks() {
    return mobile_networks;
}

public void setMobile_networks(List mobile_networks) {
    this.mobile_networks = mobile_networks;
}

def diffList(list1, list2):     # returns the difference between two lists.
    if len(list1) > len(list2):
        return (list(set(list1) - set(list2)))
    else:
        return (list(set(list2) - set(list1)))

e.g. if list1 = [10, 15, 20, 25, 30, 35, 40] and list2 = [25, 40, 35] then the returned list will be output = [10, 20, 30, 15]

this is another simple way to do it .

Name.objects.exclude(alias=None)

For the sake of completion:

 apply(people[,-1], 2, function(x) sum(x))
#Height Weight 
#   199    425 

Use the following JS:

$(document).ready(function () {
    $("#btnsubmit").click(function () {

             $.ajax({
                 type: "POST",
                 url: '/Plan/PlanManage',     //your action
                 data: $('#PlanForm').serialize(),   //your form name.it takes all the values of model               
                 dataType: 'json',
                 success: function (result) {
                     console.log(result);
                 }
             })
        return false;
    });
});

and the following code on your controller:

[HttpPost]
public string PlanManage(Plan objplan)  //model plan
{
}

You can also use it

export function diffDateAndToString(small: Date, big: Date) {


    // To calculate the time difference of two dates 
    const Difference_In_Time = big.getTime() - small.getTime()

    // To calculate the no. of days between two dates 
    const Days = Difference_In_Time / (1000 * 3600 * 24)
    const Mins = Difference_In_Time / (60 * 1000)
    const Hours = Mins / 60

    const diffDate = new Date(Difference_In_Time)

    console.log({ date: small, now: big, diffDate, Difference_In_Days: Days, Difference_In_Mins: Mins, Difference_In_Hours: Hours })

    var result = ''

    if (Mins < 60) {
        result = Mins + 'm'
    } else if (Hours < 24) result = diffDate.getMinutes() + 'h'
    else result = Days + 'd'
    return { result, Days, Mins, Hours }
}

results in { result: '30d', Days: 30, Mins: 43200, Hours: 720 }

In Scala 2.10

val name = "Ivan"
val weather = "sunny"

s"Hello $name, it's $weather today!"

You should try this (test, works at least in Firefox):

html2canvas(document.body,{
   onrendered:function(canvas){
      document.body.appendChild(canvas);
   }
});

Im running these lines of code to get the full browser screen (only the visible screen, not the hole site):

var w=window, d=document, e=d.documentElement, g=d.getElementsByTagName('body')[0];
var y=w.innerHeight||e.clientHeight||g.clientHeight;

html2canvas(document.body,{
   height:y,
   onrendered:function(canvas){
      var img = canvas.toDataURL();
   }
});

More explanations & options here: http://html2canvas.hertzen.com/#/documentation.html

I wrote an npm package called 'html-form-enhancer'. By dropping it into your HTML source, it takes over submission of forms with methods aside from GET and POST, and also adds application/json serialization.

<script type=module" src="html-form-enhancer.js"></script>

<form method="PUT">
...
</form>

I found an easier way to do it and it works perfectly even if you don't know the path where the chrome is located.

First of all, you have to paste this code in the top of the module.

Option Explicit
Private pWebAddress As String
Public Declare Function ShellExecute Lib "shell32.dll" Alias "ShellExecuteA" _
(ByVal hwnd As Long, ByVal lpOperation As String, ByVal lpFile As String, _
ByVal lpParameters As String, ByVal lpDirectory As String, ByVal nShowCmd As Long) As Long

After that you have to create this two modules:

Sub LoadExplorer()
    LoadFile "Chrome.exe" ' Here you are executing the chrome. exe
End Sub

Sub LoadFile(FileName As String)
    ShellExecute 0, "Open", FileName, "http://test.123", "", 1 ' You can change the URL.
End Sub

With this you will be able (if you want) to set a variable for the url or just leave it like hardcode.

Ps: It works perfectly for others browsers just changing "Chrome.exe" to opera, bing, etc.

Your first attempt was almost right, It should work without the quotes.

{test: obj.value1 == 'someothervalue'}

Here is a plnkr.

The ngClass directive will work with any expression that evaluates truthy or falsey, a bit similar to Javascript expressions but with some differences, you can read about here. If your conditional is too complex, then you can use a function that returns truthy or falsey, as you did in your third attempt.

Just to complement: You can also use logical operators to form logical expressions like

ng-class="{'test': obj.value1 == 'someothervalue' || obj.value2 == 'somethingelse'}"

What about this approach? Works for me. It is also used in django-registration.

def get_request_root_url(self):
    scheme = 'https' if self.request.is_secure() else 'http'
    site = get_current_site(self.request)
    return '%s://%s' % (scheme, site)

Do this to use a profile with name 'dev':

session = boto3.session.Session(profile_name='dev')
s3 = session.resource('s3')
for bucket in s3.buckets.all():
    print(bucket.name)

1 - Set CSS on parent div to display: flex;

2 - Set CSS on parent div to flex-direction: column;
Note that this will make all content within that div line up top to bottom. This will work best if the parent div only contains the child and nothing else.

3 - Set CSS on parent div to justify-content: center;

Here is an example of what the CSS will look like:

.parentDivClass {_x000D_
  display: flex;_x000D_
  flex-direction: column;_x000D_
  justify-content: center;_x000D_
}

Using SQL Server 05 I can get this to work by using:

declare @OrigValue int;
set @OrigValue = 121.25;
select replace(str(@OrigValue/3600,len(ltrim(@OrigValue/3600))+abs(sign(@OrigValue/359999)-1)) + ':' + str((@OrigValue/60)%60,2) + ':' + str(@OrigValue%60,2),' ','0')

With JavaScript:

window.parent.location.href= "http://www.google.com";

To bring the existing answers together with an important clarification:

As stated, the problem with NAME=sam echo "$NAME" is that $NAME gets expanded by the current shell before assignment NAME=sam takes effect.

Solutions that preserve the original semantics (of the (ineffective) solution attempt NAME=sam echo "$NAME"):

Use either eval^[1] (as in the question itself), or printenv (as added by Aaron McDaid to heemayl's answer), or bash -c (from Ljm Dullaart's answer), in descending order of efficiency:

NAME=sam eval 'echo "$NAME"'  # use `eval` only if you fully control the command string
NAME=sam printenv NAME
NAME=sam bash -c 'echo "$NAME"'

^{printenv is not a POSIX utility, but it is available on both Linux and macOS/BSD.}

What this style of invocation (<var>=<name> cmd ...) does is to define NAME:

• as an environment variable
• that is only defined for the command being invoked.

In other words: NAME only exists for the command being invoked, and has no effect on the current shell (if no variable named NAME existed before, there will be none after; a preexisting NAME variable remains unchanged).

POSIX defines the rules for this kind of invocation in its Command Search and Execution chapter.

The following solutions work very differently (from heemayl's answer):

NAME=sam; echo "$NAME"
NAME=sam && echo "$NAME"

While they produce the same output, they instead define:

• a shell variable NAME (only) rather than an environment variable
  • if echo were a command that relied on environment variable NAME, it wouldn't be defined (or potentially defined differently from earlier).
• that lives on after the command.

Note that every environment variable is also exposed as a shell variable, but the inverse is not true: shell variables are only visible to the current shell and its subshells, but not to child processes, such as external utilities and (non-sourced) scripts (unless they're marked as environment variables with export or declare -x).

^{[1] Technically, bash is in violation of POSIX here (as is zsh): Since eval is a special shell built-in, the preceding NAME=sam assignment should cause the the variable $NAME to remain in scope after the command finishes, but that's not what happens.
However, when you run bash in POSIX compatibility mode, it is compliant.
dash and ksh are always compliant.
The exact rules are complicated, and some aspects are left up to the implementations to decide; again, see Command Search and Execution.
Also, the usual disclaimer applies: Use eval only on input you fully control or implicitly trust.}

You should use white-space with display table

Example:
    legend {
        display:table; /* Enable line-wrapping in IE8+ */
        white-space:normal; /* Enable line-wrapping in old versions of some other browsers */
    }

With C++11 for measuring the execution time of a piece of code, we can use the now() function:

auto start = chrono::steady_clock::now();

//  Insert the code that will be timed

auto end = chrono::steady_clock::now();

// Store the time difference between start and end
auto diff = end - start;

If you want to print the time difference between start and end in the above code, you could use:

cout << chrono::duration <double, milli> (diff).count() << " ms" << endl;

If you prefer to use nanoseconds, you will use:

cout << chrono::duration <double, nano> (diff).count() << " ns" << endl;

The value of the diff variable can be also truncated to an integer value, for example, if you want the result expressed as:

diff_sec = chrono::duration_cast<chrono::nanoseconds>(diff);
cout << diff_sec.count() << endl;

Alternate solution for swift:

To make both UpperCase:

e.g:

if ("ABcd".uppercased() == "abcD".uppercased()){
}

or to make both LowerCase:

e.g:

if ("ABcd".lowercased() == "abcD".lowercased()){
}

For those who are visiting this old thread here is a package I find to be good.

https://www.npmjs.org/package/config

input.name() needs to be inside a function; classes contain declarations, not random code.

You remove the original image here:

newImg.animate(css, SPEED, function() {
    img.remove();
    newImg.removeClass('morpher');
    (callback || function() {})();
});

And all that's left behind is newImg. Then you reset link references the image using #rocket:

$("#rocket").attr('src', ...

But your newImg doesn't have an id attribute let alone an id of rocket.

To fix this, you need to remove img and then set the id attribute of newImg to rocket:

newImg.animate(css, SPEED, function() {
    var old_id = img.attr('id');
    img.remove();
    newImg.attr('id', old_id);
    newImg.removeClass('morpher');
    (callback || function() {})();
});

And then you'll get the shiny black rocket back again: http://jsfiddle.net/ambiguous/W2K9D/

UPDATE: A better approach (as noted by mellamokb) would be to hide the original image and then show it again when you hit the reset button. First, change the reset action to something like this:

$("#resetlink").click(function(){
    clearInterval(timerRocket);
    $("#wrapper").css('top', '250px');
    $('.throbber, .morpher').remove(); // Clear out the new stuff.
    $("#rocket").show();               // Bring the original back.
});

And in the newImg.load function, grab the images original size:

var orig = {
    width: img.width(),
    height: img.height()
};

And finally, the callback for finishing the morphing animation becomes this:

newImg.animate(css, SPEED, function() {
    img.css(orig).hide();
    (callback || function() {})();
});

New and improved: http://jsfiddle.net/ambiguous/W2K9D/1/

The leaking of $('.throbber, .morpher') outside the plugin isn't the best thing ever but it isn't a big deal as long as it is documented.

The following is a proposed solution for the OP's specific problem (extracting the 2nd word of a string), but it should be noted that, as mc0e's answer states, actually extracting regex matches is not supported out-of-the-box in MySQL. If you really need this, then your choices are basically to 1) do it in post-processing on the client, or 2) install a MySQL extension to support it.

BenWells has it very almost correct. Working from his code, here's a slightly adjusted version:

SUBSTRING(
  sentence,
  LOCATE(' ', sentence) + CHAR_LENGTH(' '),
  LOCATE(' ', sentence,
  ( LOCATE(' ', sentence) + 1 ) - ( LOCATE(' ', sentence) + CHAR_LENGTH(' ') )
)

As a working example, I used:

SELECT SUBSTRING(
  sentence,
  LOCATE(' ', sentence) + CHAR_LENGTH(' '),
  LOCATE(' ', sentence,
  ( LOCATE(' ', sentence) + 1 ) - ( LOCATE(' ', sentence) + CHAR_LENGTH(' ') )
) as string
FROM (SELECT 'THIS IS A TEST' AS sentence) temp

This successfully extracts the word IS

SET @ManagerID = ?
SET @ManagerEmail = ?
SET @RecordCount = ?

INSERT INTO...

you must bind it to input element only

NSLocalizedString() reads the value for the key AppleLanguages from the standard user defaults ([NSUserDefaults standardUserDefaults]). It uses that value to choose an appropriate localization among all existing localizations at runtime. When Apple builds the user defaults dictionary at app launch, they look up the preferred language(s) key in the system preferences and copy the value from there. This also explains for example why changing the language settings in OS X has no effect on running apps, only on apps started thereafter. Once copied, the value is not updated just because the settings change. That's why iOS restarts all apps if you change then language.

However, all values of the user defaults dictionary can be overwritten by command line arguments. See NSUserDefaults documentation on the NSArgumentDomain. This even includes those values that are loaded from the app preferences (.plist) file. This is really good to know if you want to change a value just once for testing.

So if you want to change the language just for testing, you probably don't want to alter your code (if you forget to remove this code later on ...), instead tell Xcode to start your app with a command line parameters (e.g. use Spanish localization):

No need to touch your code at all. Just create different schemes for different languages and you can quickly start the app once in one language and once in another one by just switching the scheme.

I don't know why the first answer is the best one, I tried it and not working in fact, as @kalys.osmonov said, you can give text-align:center to header, but you have to make ul as inline-block rather than inline, and also you have to notice that text-align can be inherited which is not good to some degree, so the better way (not working below IE 9) is using margin and transform. Just remove float right and margin;0 auto from ul, like below:

#header ul {
   /* float: right; */
   /* margin: 0 auto; */
   display: inline-block;
   margin-left: 50%; /* From parent width */
   transform: translateX(-50%); /* use self width which can be unknown */
  -ms-transform: translateX(-50%); /* For IE9 */
}

This way can fix the problem that making dynamic width of ul center if you don't care IE8 etc.

Forr me reason was that I tried to use newest MySQL Workbench 8.x to connect to MySQL Server 5.1 (both running on Windows Server 2012).

The same error occurs also when doing SELECT DISTINCT ..., <CLOB_column>, ....

If this CLOB column contains values shorter than limit for VARCHAR2 in all the applicable rows you may use to_char(<CLOB_column>) or concatenate results of multiple calls to DBMS_LOB.SUBSTR(<CLOB_column>, ...).

If you have a need to copy the exact same timestamp data, change the data type in the destination table from timestamp to binary(8) -- i used varbinary(8) and it worked fine.

This obviously breaks any timestamp functionality in the destination table, so make sure you're ok with that first.

A naming convention like this is useful when you are reading code, particularly code that is not your own. A strong naming convention helps indicate where a particular member is defined, what kind of member it is, etc. Most development teams adopt a simple naming convention, and simply prefix member fields with an underscore (_fieldName). In the past, I have used the following naming convention for C# (which is based on Microsofts conventions for the .NET framework code, which can be seen with Reflector):

Instance Field: m_fieldName
Static Field: s_fieldName
Public/Protected/Internal Member: PascalCasedName()
Private Member: camelCasedName()

This helps people understand the structure, use, accessibility and location of members when reading unfamiliar code very rapidly.

I'm also having the same issue with a very latest Tomcat server (7.0.40). It goes non-responsive once for a couple of days.

To see open connections, you may use:

sudo netstat -tonp | grep jsvc | grep --regexp="127.0.0.1:443" --regexp="127.0.0.1:80" | grep CLOSE_WAIT

As mentioned in this post, you may use /proc/sys/net/ipv4/tcp_keepalive_time to view the values. The value seems to be in seconds and defaults to 7200 (i.e. 2 hours).

To change them, you need to edit /etc/sysctl.conf.

Open/create `/etc/sysctl.conf`
Add `net.ipv4.tcp_keepalive_time = 120` and save the file
Invoke `sysctl -p /etc/sysctl.conf`
Verify using `cat /proc/sys/net/ipv4/tcp_keepalive_time`

I would do something like the following:

INSERT INTO cache VALUES (key, generation)
ON DUPLICATE KEY UPDATE (key = key, generation = generation + 1);

Setting the generation value to 0 in code or in the sql but the using the ON DUP... to increment the value. I think that's the syntax anyway.

It is possible to use Object.defineProperty() in order to redefine the 'value' property of the input element and do anything during its changing.

Object.defineProperty() allows us to define a getter and setter for a property, thus controlling it.

replaceWithWrapper($("#hid1")[0], "value", function(obj, property, value) { 
  console.log("new value:", value)
});

function replaceWithWrapper(obj, property, callback) {
  Object.defineProperty(obj, property, new function() {
    var _value = obj[property];
    return {
      set: function(value) {
        _value = value;
        callback(obj, property, value)
      },
      get: function() {
        return _value;
      }
    }
  });
}

$("#hid1").val(4);

The best solution I could find at present time to open a window maximized is (Internet Explorer 11, Chrome 49, Firefox 45):

  var popup = window.open("your_url", "popup", "fullscreen");
  if (popup.outerWidth < screen.availWidth || popup.outerHeight < screen.availHeight)
  {
    popup.moveTo(0,0);
    popup.resizeTo(screen.availWidth, screen.availHeight);

Note 1: It does not work on Edge (13.1058686). Not sure whether it's a bug or if it's as designed (I've filled a bug report, we'll see what they have to say about it). Here is a workaround:

if (navigator.userAgent.match(/Edge\/\d+/g))
{
    return window.open("your_url", "popup", "width=" + screen.width + ",height=" + screen.height);
}

Note 2: moveTo or resizeTo will not work (Access denied) if the window you are opening is on another domain.

Rename MySQL Column with ALTER TABLE Command

ALTER TABLE is an essential command used to change the structure of a MySQL table. You can use it to add or delete columns, change the type of data within the columns, and even rename entire databases. The function that concerns us the most is how to utilize ALTER TABLE to rename a column.

Clauses give us additional control over the renaming process. The RENAME COLUMN and CHANGE clause both allow for the names of existing columns to be altered. The difference is that the CHANGE clause can also be used to alter the data types of a column. The commands are straightforward, and you may use the clause that fits your requirements best.

How to Use the RENAME COLUMN Clause (MySQL 8.0)

The simplest way to rename a column is to use the ALTER TABLE command with the RENAME COLUMN clause. This clause is available since MySQL version 8.0.

Let’s illustrate its simple syntax. To change a column name, enter the following statement in your MySQL shell:

ALTER TABLE your_table_name RENAME COLUMN original_column_name TO new_column_name;

Exchange the your_table_name, original_column_name, and new_column_name with your table and column names. Keep in mind that you cannot rename a column to a name that already exists in the table.

Note: The word COLUMN is obligatory for the ALTER TABLE RENAME COLUMN command. ALTER TABLE RENAME is the existing syntax to rename the entire table.

The RENAME COLUMN clause can only be used to rename a column. If you need additional functions, such as changing the data definition, or position of a column, you need to use the CHANGE clause instead.

Rename MySQL Column with CHANGE Clause

The CHANGE clause offers important additions to the renaming process. It can be used to rename a column and change the data type of that column with the same command.

Enter the following command in your MySQL client shell to change the name of the column and its definition:

ALTER TABLE your_table_name CHANGE original_column_name new_col_name data_type;

The data_type element is mandatory, even if you want to keep the existing datatype.

Use additional options to further manipulate table columns. The CHANGE also allows you to place the column in a different position in the table by using the optional FIRST | AFTER column_name clause. For example:

ALTER TABLE your_table_name CHANGE original_column_name new_col_name y_data_type AFTER column_x;

You have successfully changed the name of the column, changed the data type to y_data_type, and positioned the column after column_x.

You can do this a couple of ways.

Via the "Solution Explorer"

1. Simply right-click the "References" folder and select "Manage NuGet Packages..."
2. Once that window comes up click on the option labeled "Online" in the left most part of the dialog.
3. Then in the search bar in the upper right type "json.net"
4. Click "Install" and you're done.

Via the "Package Manager Console"

1. Open the console. "View" > "Other Windows" > "Package Manager Console"
2. Then type the following:

   Install-Package Newtonsoft.Json

For more info on how to use the "Package Manager Console" check out the nuget docs.

Short answer:

Just install the latest version of nodejs and then restart your system.

more description:

It's related to Environment variables in your system at least as far as I know, you can make changes in path variable in your system as others talked about it in the current thread but the easiest way to solve this is installing nodejs!

I was getting the same UnicodeEncodeError when saving scraped web content to a file. To fix it I replaced this code:

with open(fname, "w") as f:
    f.write(html)

with this:

import io
with io.open(fname, "w", encoding="utf-8") as f:
    f.write(html)

Using io gives you backward compatibility with Python 2.

If you only need to support Python 3 you can use the builtin open function instead:

with open(fname, "w", encoding="utf-8") as f:
    f.write(html)

Why not just use, toggleClass on click?

js:

$(this).toggleClass("up");

css:

button.up {
    -webkit-transform: rotate(180deg);
       -moz-transform: rotate(180deg);
        -ms-transform: rotate(180deg);
         -o-transform: rotate(180deg);
            transform: rotate(180deg);
               /* IE6–IE9 */
               filter: progid:DXImageTransform.Microsoft.Matrix(M11=0.9914448613738104, M12=-0.13052619222005157,M21=0.13052619222005157, M22=0.9914448613738104, sizingMethod='auto expand');
                 zoom: 1;
    }

you can also add this to the css:

button{
        -webkit-transition: all 500ms ease-in-out;
        -moz-transition: all 500ms ease-in-out;
        -o-transition: all 500ms ease-in-out;
        -ms-transition: all 500ms ease-in-out;
}

which will add the animation.

PS...

to answer your original question:

you said that it rotates but never stops. When using set timeout you need to make sure you have a condition that will not call settimeout or else it will run forever. So for your code:

<script type="text/javascript">
    $(function() {
     var $elie = $("#bkgimg");
     rotate(0);
     function rotate(degree) {

      // For webkit browsers: e.g. Chrome
    $elie.css({ WebkitTransform: 'rotate(' + degree + 'deg)'});
      // For Mozilla browser: e.g. Firefox
    $elie.css({ '-moz-transform': 'rotate(' + degree + 'deg)'});


    /* add a condition here for the extremity */ 
    if(degree < 180){
      // Animate rotation with a recursive call
      setTimeout(function() { rotate(++degree); },65);
     }
    }
    });
    </script>

import os
for root, dirs, files in os.walk(top, topdown=False):
    for name in dirs:
        print os.path.join(root, name)

Walk is a good built-in for what you are doing

Converting the list to a data frame within the append function works, also when applied in a loop

import pandas as pd
mylist = [1,2,3]
df = pd.DataFrame()
df = df.append(pd.DataFrame(data[mylist]))

Using a custom attribute (implemented with a directive) is perhaps the cleanest way. Here's my version, based on @Josh and @sean's suggestions.

angular.module('mymodule', [])

// Click to navigate
// similar to <a href="#/partial"> but hash is not required, 
// e.g. <div click-link="/partial">
.directive('clickLink', ['$location', function($location) {
    return {
        link: function(scope, element, attrs) {
            element.on('click', function() {
                scope.$apply(function() {
                    $location.path(attrs.clickLink);
                });
            });
        }
    }
}]);

It has some useful features, but I'm new to Angular so there's probably room for improvement.

Just set the body as the following

var reqBody = "username="+username+"&password="+password+"&grant_type=password";

then

fetch('url', {
      method: 'POST',
      headers: {
          //'Authorization': 'Bearer token',
          'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8'
      },
      body: reqBody
  }).then((response) => response.json())
      .then((responseData) => {
          console.log(JSON.stringify(responseData));
      }).catch(err=>{console.log(err)})

select (floor(((DATE2-DATE1)*24*60*60)/3600)|| ' : ' ||floor((((DATE2-DATE1)*24*60*60) -floor(((DATE2-DATE1)*24*60*60)/3600)*3600)/60)|| '  ' ) as time_difference from TABLE1 

If you want more Thread to be created, in above case you have to repeat the code inside run method or at least repeat calling some method inside.

Try this, which will help you to call as many times you needed. It will be helpful when you need to execute your run more then once and from many place.

class A extends Thread {
    public void run() {
             //Code you want to get executed seperately then main thread.       
    }
     }

Main class

A obj1 = new A();
obj1.start();

A obj2 = new A();
obj2.start();

You can use built-in map function:

result = map(lambda x: x * P, S)

or list comprehensions that is a bit more pythonic:

result = [x * P for x in S]

You can use Environment.Exit(0) and Application.Exit.

Environment.Exit(): terminates this process and gives the underlying operating system the specified exit code.

I ran into this problem when I checked out an older version of a repository from git. Git replaced my .py files, but left the untracked .pyc files. Since the .py files and .pyc files were out of sync, the import command in a .py file could not find the corresponding module in the .pyc files.

The solution was simply to delete the .pyc files, and let them be automatically regenerated.

You need to tell the compiler you want to do String concatenation by starting the sequence with a string, even an empty one. Like so:

System.out.println("" + char1 + char2 + char3...);

The two previous answers demonstrate how to use Canvas and ImageData. I would like to propose an answer with runnable example and using an image processing framework, so you don't need to handle the pixel data manually.

MarvinJ provides the method image.getAlphaComponent(x,y) which simply returns the transparency value for the pixel in x,y coordinate. If this value is 0, pixel is totally transparent, values between 1 and 254 are transparency levels, finally 255 is opaque.

For demonstrating I've used the image below (300x300) with transparent background and two pixels at coordinates (0,0) and (150,150).

Console output:

(0,0): TRANSPARENT
(150,150): NOT_TRANSPARENT

image = new MarvinImage();_x000D_
image.load("https://i.imgur.com/eLZVbQG.png", imageLoaded);_x000D_

  console.log("(150,150): "+(image.getAlphaComponent(150,150) > 0 ? "NOT_TRANSPARENT" : "TRANSPARENT"));_x000D_

Just as reference let me quote the osxfuse FAQ

4.8. How should I unmount my "FUSE for OS X" file system? I cannot find the fusermount program anywhere.

Just use the standard umount command in OS X. You do not need the Linux-specific fusermount with "FUSE for OS X".

As mentioned above, either diskutil unmount or umount should work

The problem is not with the splitting but rather with the WriteLine. A \n in a string printed with WriteLine will produce an "extra" line.

Example

var text = 
  "somet interesting text\n" +
  "some text that should be in the same line\r\n" +
  "some text should be in another line";

string[] stringSeparators = new string[] { "\r\n" };
string[] lines = text.Split(stringSeparators, StringSplitOptions.None);
Console.WriteLine("Nr. Of items in list: " + lines.Length); // 2 lines
foreach (string s in lines)
{
   Console.WriteLine(s); //But will print 3 lines in total.
}

To fix the problem remove \n before you print the string.

Console.WriteLine(s.Replace("\n", ""));
