I have a span. I want to take the value of attribute data-txt-lang, which is used defined.

$(document).ready(function ()
{
<span class="txt-lang-btn" data-txt-lang="en">EN</span>
alert($('.txt-lang-btn').attr('data-txt-lang'));
});

I am doing it like

public enum State
{
    // Retrieving, // the MediaRetriever is retrieving music //
    Stopped, // media player is stopped and not prepared to play
    Preparing, // media player is preparing...
    Playing, // playback active (media player ready!). (but the media player
                // may actually be
                // paused in this state if we don't have audio focus. But we
                // stay in this state
                // so that we know we have to resume playback once we get
                // focus back)
    Paused; // playback paused (media player ready!)

    //public final static State[] vals = State.values();//copy the values(), calling values() clones the array

};

public State getState()
{
        return mState;   
}

And use in Switch Statement

switch (mService.getState())
{
case Stopped:
case Paused:

    playPause.setBackgroundResource(R.drawable.selplay);
    break;

case Preparing:
case Playing:

    playPause.setBackgroundResource(R.drawable.selpause);
    break;    
}

To generate a shared library you need first to compile your C code with the -fPIC (position independent code) flag.

gcc -c -fPIC hello.c -o hello.o

This will generate an object file (.o), now you take it and create the .so file:

gcc hello.o -shared -o libhello.so

EDIT: Suggestions from the comments:

You can use

gcc -shared -o libhello.so -fPIC hello.c

to do it in one step. – Jonathan Leffler

I also suggest to add -Wall to get all warnings, and -g to get debugging information, to your gcc commands. – Basile Starynkevitch

I like using this one if I only have one link on the page:

onMouseOver="this.style.cursor='pointer'"

I was looking for a solution to add an UIImage to my UIButton. The problem was just it displays the image bigger than needed. Just helped me with this:

_imageViewBackground = [[UIImageView alloc] initWithFrame:rectImageView];
_imageViewBackground.image = [UIImage imageNamed:@"gradientBackgroundPlain"];
[self addSubview:_imageViewBackground];
[self insertSubview:_imageViewBackground belowSubview:self.label];
_imageViewBackground.hidden = YES;

Every time I want to display my UIImageView I just set the var hidden to YES or NO. There might be other solutions but I got confused so many times with this stuff and this solved it and I didn't need to deal with internal stuff UIButton is doing in background.

To Add a little to the above answers:

If you are wanting to commit a folder like the above

git add foldername
git commit -m "commit operation"

To add the folder you will need to be on the same level as, or above, the folder you are trying to add.

For example: App/Storage/Emails/email.php

If you are trying to add the "Storage" file but you have been working inside it on the email.php document you will not be able to add the "Storage" file unless you have 'changed directory' (cd ../) back up to the same level, or higher, as the Storage file itself

Problem with finishAffinity() is that only activities in your current task are closed, but activities with singleInstance launchMode and in other tasks are still opened and brought to the foreground after finishAffinity(). The problem with System.exit(0) is that you finish your App process with all background services and all allocated memory and this can lead to undesired side effects (e.g. not receiving notifications anymore).

Here are other two alternatives that solve both problems:

1. Use ActivityLifecycleCallbacks in you app class to register created activities and close them when needed: https://gist.github.com/sebaslogen/5006ec133243379d293f9d6221100ddb#file-myandroidapplication-kt-L10
2. In testing you can use ActivityLifecycleMonitorRegistry: https://github.com/sebaslogen/CleanGUITestArchitecture/blob/master/app/src/androidTest/java/com/neoranga55/cleanguitestarchitecture/util/ActivityFinisher.java#L15

Try this one:

    <textarea cols='60' rows='8'>This is my statement one.&#13;&#10;This is my statement2</textarea>


 Line Feed and 
 Carriage Return are HTML entities^wikipedia. This way you are actually parsing the new line ("\n") rather than displaying it as text.

select format(convert(float,@your_column),'0.0#########')

Advantage: This solution is irrespective of the source datatype (float, scientific, varchar, date etc)

String is limited to 10 digits, bigInt gets rid of decimal values

Just to keep this up to date:

The current version of SQLDeveloper has an export tool (Tools > Database Export) that will allow you to dump a schema to a file, with filters for object types, object names, table data etc.

It's a fair amount easier to set-up and use than exp and imp if you're used to working in a GUI environment, but not as versatile if you need to use it for scripting anything.

Ensure you have included the different abiFilters, this enables Gradle know what ABI libraries to package into your apk.

defaultConfig {
 ndk { 
       abiFilters "armeabi-v7a", "x86", "armeabi", "mips" 
     } 
  }

If you storing your jni libs in a different directory, or also using externally linked jni libs, Include them on the different source sets of the app.

sourceSets { 
  main { 
    jni.srcDirs = ['src/main/jniLibs'] 
    jniLibs.srcDir 'src/main/jniLibs' 
    } 
}

Given: [x1,x2] [y1,y2] then x1 <= y2 || x2 >= y1 would work always. as

      x1 ... x2
y1 .... y2

if x1 > y2 then they do not overlap or

x1 ... x2
    y1 ... y2

if x2 < y1 they do not overlap.

Similar to the other examples, but using html sizing, I use:

<img src="image1.png" width="425"/> <img src="image2.png" width="425"/> 

Here is an example

<img src="https://openclipart.org/image/2400px/svg_to_png/28580/kablam-Number-Animals-1.png" width="200"/> <img src="https://openclipart.org/download/71101/two.svg" width="300"/>

I tested this using Remarkable.

An LRUMap is another possibility, also from Apache Commons.

http://commons.apache.org/collections/apidocs/org/apache/commons/collections/map/LRUMap.html

Using ClassLoader.getSystemClassLoader()

Sample code :

Properties prop = new Properties();
InputStream input = null;
try {
    input = ClassLoader.getSystemClassLoader().getResourceAsStream("conf.properties");
    prop.load(input);

} catch (IOException io) {
    io.printStackTrace();
}

[this answer is a bit dated: read the edits]

Say hello to your friends: map and filter and reduce and forEach and every etc.

(I only occasionally write for-loops in javascript, because of block-level scoping is missing, so you have to use a function as the body of the loop anyway if you need to capture or clone your iteration index or value. For-loops are more efficient generally, but sometimes you need a closure.)

The most readable way:

[....].filter(x => x==2).length

(We could have written .filter(function(x){return x==2}).length instead)

The following is more space-efficient (O(1) rather than O(N)), but I'm not sure how much of a benefit/penalty you might pay in terms of time (not more than a constant factor since you visit each element exactly once):

[....].reduce((total,x) => (x==2 ? total+1 : total), 0)

(If you need to optimize this particular piece of code, a for loop might be faster on some browsers... you can test things on jsperf.com.)

You can then be elegant and turn it into a prototype function:

[1, 2, 3, 5, 2, 8, 9, 2].count(2)

Like this:

Object.defineProperties(Array.prototype, {
    count: {
        value: function(value) {
            return this.filter(x => x==value).length;
        }
    }
});

You can also stick the regular old for-loop technique (see other answers) inside the above property definition (again, that would likely be much faster).

2017 edit:

Whoops, this answer has gotten more popular than the correct answer. Actually, just use the accepted answer. While this answer may be cute, the js compilers probably don't (or can't due to spec) optimize such cases. So you should really write a simple for loop:

Object.defineProperties(Array.prototype, {
    count: {
        value: function(query) {
            /* 
               Counts number of occurrences of query in array, an integer >= 0 
               Uses the javascript == notion of equality.
            */
            var count = 0;
            for(let i=0; i<this.length; i++)
                if (this[i]==query)
                    count++;
            return count;
        }
    }
});

You could define a version .countStrictEq(...) which used the === notion of equality. The notion of equality may be important to what you're doing! (for example [1,10,3,'10'].count(10)==2, because numbers like '4'==4 in javascript... hence calling it .countEq or .countNonstrict stresses it uses the == operator.)

Also consider using your own multiset data structure (e.g. like python's 'collections.Counter') to avoid having to do the counting in the first place.

class Multiset extends Map {
    constructor(...args) {
        super(...args);
    }
    add(elem) {
        if (!this.has(elem))
            this.set(elem, 1);
        else
            this.set(elem, this.get(elem)+1);
    }
    remove(elem) {
        var count = this.has(elem) ? this.get(elem) : 0;
        if (count>1) {
            this.set(elem, count-1);
        } else if (count==1) {
            this.delete(elem);
        } else if (count==0)
            throw `tried to remove element ${elem} of type ${typeof elem} from Multiset, but does not exist in Multiset (count is 0 and cannot go negative)`;
            // alternatively do nothing {}
    }
}

Demo:

> counts = new Multiset([['a',1],['b',3]])
Map(2) {"a" => 1, "b" => 3}

> counts.add('c')
> counts
Map(3) {"a" => 1, "b" => 3, "c" => 1}

> counts.remove('a')
> counts
Map(2) {"b" => 3, "c" => 1}

> counts.remove('a')
Uncaught tried to remove element a of type string from Multiset, but does not exist in Multiset (count is 0 and cannot go negative)

sidenote: Though, if you still wanted the functional-programming way (or a throwaway one-liner without overriding Array.prototype), you could write it more tersely nowadays as [...].filter(x => x==2).length. If you care about performance, note that while this is asymptotically the same performance as the for-loop (O(N) time), it may require O(N) extra memory (instead of O(1) memory) because it will almost certainly generate an intermediate array and then count the elements of that intermediate array.

to Hide All Errors:

error_reporting(0);
ini_set('display_errors', 0);

to Show All Errors:

error_reporting(E_ALL);
ini_set('display_errors', 1);

I would recommend to look at the error_logs, specifically at the upstream part where it shows specific upstream that is timing out.

Then based on that you can adjust proxy_read_timeout, fastcgi_read_timeout or uwsgi_read_timeout.

Also make sure your config is loaded.

More details here Nginx upstream timed out (why and how to fix)

Two major differences between apply and transform

There are two major differences between the transform and apply groupby methods.

• Input:
• apply implicitly passes all the columns for each group as a DataFrame to the custom function.
• while transform passes each column for each group individually as a Series to the custom function.
• Output:
• The custom function passed to apply can return a scalar, or a Series or DataFrame (or numpy array or even list).
• The custom function passed to transform must return a sequence (a one dimensional Series, array or list) the same length as the group.

So, transform works on just one Series at a time and apply works on the entire DataFrame at once.

Inspecting the custom function

It can help quite a bit to inspect the input to your custom function passed to apply or transform.

Examples

Let's create some sample data and inspect the groups so that you can see what I am talking about:

import pandas as pd
import numpy as np
df = pd.DataFrame({'State':['Texas', 'Texas', 'Florida', 'Florida'], 
                   'a':[4,5,1,3], 'b':[6,10,3,11]})

     State  a   b
0    Texas  4   6
1    Texas  5  10
2  Florida  1   3
3  Florida  3  11

Let's create a simple custom function that prints out the type of the implicitly passed object and then raised an error so that execution can be stopped.

def inspect(x):
    print(type(x))
    raise

Now let's pass this function to both the groupby apply and transform methods to see what object is passed to it:

df.groupby('State').apply(inspect)

<class 'pandas.core.frame.DataFrame'>
<class 'pandas.core.frame.DataFrame'>
RuntimeError

As you can see, a DataFrame is passed into the inspect function. You might be wondering why the type, DataFrame, got printed out twice. Pandas runs the first group twice. It does this to determine if there is a fast way to complete the computation or not. This is a minor detail that you shouldn't worry about.

Now, let's do the same thing with transform

df.groupby('State').transform(inspect)
<class 'pandas.core.series.Series'>
<class 'pandas.core.series.Series'>
RuntimeError

It is passed a Series - a totally different Pandas object.

So, transform is only allowed to work with a single Series at a time. It is impossible for it to act on two columns at the same time. So, if we try and subtract column a from b inside of our custom function we would get an error with transform. See below:

def subtract_two(x):
    return x['a'] - x['b']

df.groupby('State').transform(subtract_two)
KeyError: ('a', 'occurred at index a')

We get a KeyError as pandas is attempting to find the Series index a which does not exist. You can complete this operation with apply as it has the entire DataFrame:

df.groupby('State').apply(subtract_two)

State     
Florida  2   -2
         3   -8
Texas    0   -2
         1   -5
dtype: int64

The output is a Series and a little confusing as the original index is kept, but we have access to all columns.

Displaying the passed pandas object

It can help even more to display the entire pandas object within the custom function, so you can see exactly what you are operating with. You can use print statements by I like to use the display function from the IPython.display module so that the DataFrames get nicely outputted in HTML in a jupyter notebook:

from IPython.display import display
def subtract_two(x):
    display(x)
    return x['a'] - x['b']

Screenshot:

Transform must return a single dimensional sequence the same size as the group

The other difference is that transform must return a single dimensional sequence the same size as the group. In this particular instance, each group has two rows, so transform must return a sequence of two rows. If it does not then an error is raised:

def return_three(x):
    return np.array([1, 2, 3])

df.groupby('State').transform(return_three)
ValueError: transform must return a scalar value for each group

The error message is not really descriptive of the problem. You must return a sequence the same length as the group. So, a function like this would work:

def rand_group_len(x):
    return np.random.rand(len(x))

df.groupby('State').transform(rand_group_len)

          a         b
0  0.962070  0.151440
1  0.440956  0.782176
2  0.642218  0.483257
3  0.056047  0.238208

Returning a single scalar object also works for transform

If you return just a single scalar from your custom function, then transform will use it for each of the rows in the group:

def group_sum(x):
    return x.sum()

df.groupby('State').transform(group_sum)

   a   b
0  9  16
1  9  16
2  4  14
3  4  14

This is my implementation (based in: https://gist.github.com/3782074):

Usage: HTML:

<table class="download">...</table>
<a href="" download="name.csv">DOWNLOAD CSV</a>

JS:

$("a[download]").click(function(){
    $("table.download").toCSV(this);    
});

Code:

jQuery.fn.toCSV = function(link) {
  var $link = $(link);
  var data = $(this).first(); //Only one table
  var csvData = [];
  var tmpArr = [];
  var tmpStr = '';
  data.find("tr").each(function() {
      if($(this).find("th").length) {
          $(this).find("th").each(function() {
            tmpStr = $(this).text().replace(/"/g, '""');
            tmpArr.push('"' + tmpStr + '"');
          });
          csvData.push(tmpArr);
      } else {
          tmpArr = [];
             $(this).find("td").each(function() {
                  if($(this).text().match(/^-{0,1}\d*\.{0,1}\d+$/)) {
                      tmpArr.push(parseFloat($(this).text()));
                  } else {
                      tmpStr = $(this).text().replace(/"/g, '""');
                      tmpArr.push('"' + tmpStr + '"');
                  }
             });
          csvData.push(tmpArr.join(','));
      }
  });
  var output = csvData.join('\n');
  var uri = 'data:application/csv;charset=UTF-8,' + encodeURIComponent(output);
  $link.attr("href", uri);
}

Notes:

• It uses "th" tags for headings. If they are not present, they are not added.
• This code detects numbers in the format: -####.## (You will need modify the code in order to accept other formats, e.g. using commas).

UPDATE:

My previous implementation worked fine but it didn't set the csv filename. The code was modified to use a filename but it requires an < a > element. It seems that you can't dynamically generate the < a > element and fire the "click" event (perhaps security reasons?).

DEMO

http://jsfiddle.net/nLj74t0f/

(Unfortunately jsfiddle fails to generate the file and instead it throws an error: 'please use POST request', don't let that error stop you from testing this code in your application).

When maven is working outside of Eclipse, but giving this error after a JDK change, Go to your Maven Run Configuration, and at the bottom of the Main page, there's a 'Maven Runtime' option. Mine was using the Embedded Maven, so after switching it to use my external maven, it worked.

When applying patches using TortoiseSVN, I typically save the path in the root of the checked out repository. You should then be able to right click on the patch, go to the TortoiseSVN menu, and click ApplyPatch. ApplyPatch should automatically figure out which level in the directory hierarchy the patch was created.

I have, however, had issues in the past with applying patches that contain new files, or which involve renames to files. Whatever algorithm Tortoise uses for this doesn't seem to handle those scenarios very well. Unicode can give you similar issues.

If the element is currently not visible on the page, you can use the native scrollIntoView() method.

$('#div_' + element_id)[0].scrollIntoView( true );

Where true means align to the top of the page, and false is align to bottom.

Otherwise, there's a scrollTo() plugin for jQuery you can use.

Or maybe just get the top position()^(docs) of the element, and set the scrollTop()^(docs) to that position:

var top = $('#div_' + element_id).position().top;
$(window).scrollTop( top );

This issue is resolved after spending few hours and i got it working. which is believe is the simplest way to solve the pagination with angular material. - Do first start by working on (component.html) file

 <mat-paginator [pageSizeOptions]="[2, 5, 10, 15, 20]" showFirstLastButtons>
 </mat-paginator>

and do in the (component.ts) file

 import { MatPaginator } from '@angular/material/paginator';
 import { Component, OnInit, ViewChild } from '@angular/core';

 export interface UserData {
 full_name: string;
 email: string;
 mob_number: string;
 }

 export class UserManagementComponent implements OnInit{
  dataSource : MatTableDataSource<UserData>;

  @ViewChild(MatPaginator) paginator: MatPaginator;

  constructor(){
    this.userList();
   }

    ngOnInit() { }

   public userList() {

   this._userManagementService.userListing().subscribe(
      response => {

      console.log(response['results']);
      this.dataSource = new MatTableDataSource<UserData>(response['results']);
      this.dataSource.paginator = this.paginator;
      console.log(this.dataSource);

     },


      error => {});

     }

 }

Remember Must import the pagination module in your currently working module(module.ts) file.

  import {MatPaginatorModule} from '@angular/material/paginator';

   @NgModule({
      imports: [MatPaginatorModule]
    })

Hope it will Work for you.

I solved the AVD problem with the flutter using the Flutter console.

Step 1:

C: \ Users \ valer> flutter emulators

This is from Github's support:

Hey Waldyr,

Markdown doesn't allow you to tweak alignment directly (see docs here: http://daringfireball.net/projects/markdown/syntax#img), but you can just use a raw HTML 'img' tag and do the alignment with inline css.

Cheers,

So it is possible to align images! You just have to use inline css to solve the problem. You can take an example from my github repo. At the bottom of README.md there is a centered aligned image. For simplicity you can just do as follows:

<p align="center">
  <img src="http://some_place.com/image.png" />
</p>

Although, as nulltoken said, it would be borderline against the Markdown philosophy!

This code from my readme:

<p align="center">
  <img src="https://github.com/waldyr/Sublime-Installer/blob/master/sublime_text.png?raw=true" alt="Sublime's custom image"/>
</p>

Produces this image output, except centered when viewed on GitHub:

<p align="center">
  <img src="https://github.com/waldyr/Sublime-Installer/blob/master/sublime_text.png?raw=true" alt="Sublime's custom image"/>
</p>

If you don't want to use the KnockoutValidation library you can write your own. Here's an example for a Mandatory field.

Add a javascript class with all you KO extensions or extenders, and add the following:

ko.extenders.required = function (target, overrideMessage) {
    //add some sub-observables to our observable
    target.hasError = ko.observable();
    target.validationMessage = ko.observable();

    //define a function to do validation
    function validate(newValue) {
    target.hasError(newValue ? false : true);
    target.validationMessage(newValue ? "" : overrideMessage || "This field is required");
    }

    //initial validation
    validate(target());

    //validate whenever the value changes
    target.subscribe(validate);

    //return the original observable
    return target;
};

Then in your viewModel extend you observable by:

self.dateOfPayment: ko.observable().extend({ required: "" }),

There are a number of examples online for this style of validation.

For what it's worth, here's the previously provided code encapsulated within a function.

openWindowWithPost("http://www.example.com/index.php", {
    p: "view.map",
    coords: encodeURIComponent(coords)
});

Function definition:

function openWindowWithPost(url, data) {
    var form = document.createElement("form");
    form.target = "_blank";
    form.method = "POST";
    form.action = url;
    form.style.display = "none";

    for (var key in data) {
        var input = document.createElement("input");
        input.type = "hidden";
        input.name = key;
        input.value = data[key];
        form.appendChild(input);
    }

    document.body.appendChild(form);
    form.submit();
    document.body.removeChild(form);
}

For a project of mine, I needed to create intervals for time-series modeling, and to make the procedure more efficient I created tsmoothie: A python library for time-series smoothing and outlier detection in a vectorized way.

It provides different smoothing algorithms together with the possibility to computes intervals.

Here I use a ConvolutionSmoother but you can also test it others.

import numpy as np
import matplotlib.pyplot as plt
from tsmoothie.smoother import *

x = np.linspace(0,2*np.pi,100)
y = np.sin(x) + np.random.random(100) * 0.2

# operate smoothing
smoother = ConvolutionSmoother(window_len=5, window_type='ones')
smoother.smooth(y)

# generate intervals
low, up = smoother.get_intervals('sigma_interval', n_sigma=2)

# plot the smoothed timeseries with intervals
plt.figure(figsize=(11,6))
plt.plot(smoother.smooth_data[0], linewidth=3, color='blue')
plt.plot(smoother.data[0], '.k')
plt.fill_between(range(len(smoother.data[0])), low[0], up[0], alpha=0.3)

I point out also that tsmoothie can carry out the smoothing of multiple timeseries in a vectorized way

If you want to remove all double quotes in string, use

var str = '"some "quoted" string"';
console.log( str.replace(/"/g, '') );
// some quoted string

Otherwise you want to remove only quotes around the string, use:

var str = '"some "quoted" string"';
console.log( clean = str.replace(/^"|"$/g, '') );
// some "quoted" string

To find a value and select it:

private void selectValue(Spinner spinner, Object value) {
    for (int i = 0; i < spinner.getCount(); i++) {
        if (spinner.getItemAtPosition(i).equals(value)) {
            spinner.setSelection(i);
            break;
        }
    }
}

One main reason that recursive mutexes are useful is in case of accessing the methods multiple times by the same thread. For example, say if mutex lock is protecting a bank A/c to withdraw, then if there is a fee also associated with that withdrawal, then the same mutex has to be used.

Pure javascript would be like this

var children = document.getElementById('test').children;

If you are using jQuery it would be like this

$("#test").children()

Since PikkuKatja and glallen asked for a more general solution and I cannot comment yet, I'll write an answer. You can combine statements as in:

> df[df=="" | df==12] <- NA
> df
     A    B
1  <NA> <NA>
2  xyz  <NA>
3  jkl  100

For factors, zxzak's code already yields factors:

> df <- data.frame(list(A=c("","xyz","jkl"), B=c(12,"",100)))
> str(df)
'data.frame':   3 obs. of  2 variables:
 $ A: Factor w/ 3 levels "","jkl","xyz": 1 3 2
 $ B: Factor w/ 3 levels "","100","12": 3 1 2

If in trouble, I'd suggest to temporarily drop the factors.

df[] <- lapply(df, as.character)

ReSTful APIs are consumed primarily by other systems, which is why I put paging data in the response headers. However, some API consumers may not have direct access to the response headers, or may be building a UX over your API, so providing a way to retrieve (on demand) the metadata in the JSON response is a plus.

I believe your implementation should include machine-readable metadata as a default, and human-readable metadata when requested. The human-readable metadata could be returned with every request if you like or, preferably, on-demand via a query parameter, such as include=metadata or include_metadata=true.

In your particular scenario, I would include the URI for each product with the record. This makes it easy for the API consumer to create links to the individual products. I would also set some reasonable expectations as per the limits of my paging requests. Implementing and documenting default settings for page size is an acceptable practice. For example, GitHub's API sets the default page size to 30 records with a maximum of 100, plus sets a rate limit on the number of times you can query the API. If your API has a default page size, then the query string can just specify the page index.

In the human-readable scenario, when navigating to /products?page=5&per_page=20&include=metadata, the response could be:

{
  "_metadata": 
  {
      "page": 5,
      "per_page": 20,
      "page_count": 20,
      "total_count": 521,
      "Links": [
        {"self": "/products?page=5&per_page=20"},
        {"first": "/products?page=0&per_page=20"},
        {"previous": "/products?page=4&per_page=20"},
        {"next": "/products?page=6&per_page=20"},
        {"last": "/products?page=26&per_page=20"},
      ]
  },
  "records": [
    {
      "id": 1,
      "name": "Widget #1",
      "uri": "/products/1"
    },
    {
      "id": 2,
      "name": "Widget #2",
      "uri": "/products/2"
    },
    {
      "id": 3,
      "name": "Widget #3",
      "uri": "/products/3"
    }
  ]
}

For machine-readable metadata, I would add Link headers to the response:

Link: </products?page=5&perPage=20>;rel=self,</products?page=0&perPage=20>;rel=first,</products?page=4&perPage=20>;rel=previous,</products?page=6&perPage=20>;rel=next,</products?page=26&perPage=20>;rel=last

(the Link header value should be urlencoded)

...and possibly a custom total-count response header, if you so choose:

total-count: 521

The other paging data revealed in the human-centric metadata might be superfluous for machine-centric metadata, as the link headers let me know which page I am on and the number per page, and I can quickly retrieve the number of records in the array. Therefore, I would probably only create a header for the total count. You can always change your mind later and add more metadata.

As an aside, you may notice I removed /index from your URI. A generally accepted convention is to have your ReST endpoint expose collections. Having /index at the end muddies that up slightly.

These are just a few things I like to have when consuming/creating an API. Hope that helps!

if(isnull({uspRptMonthlyGasRevenueByGas;1.YearTotal})) = true then
   "nd"
else
    totext({uspRptMonthlyGasRevenueByGas;1.YearTotal},'###.00')

The above logic should be what you are looking for.

The following site uses System.Management to accomplish the same is a very sleek way in a console application

and awk as well

awk 'NR!~/^(5|10|25)$/' file

The problem with all these is they don't address if the lines of text are long and much wider that the div overflow:auto does not ad a scroll bar that works right. Here is the perfect solution I found:

Create two divs. An inner div that is wide enough to handle the widest line of text and then a smaller outer one which acts at the holder for the inner div:

<div style="border:2px inset #AAA;cursor:text;height:120px;overflow:auto;width:500px;">
    <div style="width:800px;">

     now really long text like this can be put in the text area and it will really <br/>
     look and act more like a real text area bla bla bla <br/>

    </div>
</div>

To get this in a ListFragment:

getListView().setTranscriptMode(ListView.TRANSCRIPT_MODE_ALWAYS_SCROLL); 
getListView().setStackFromBottom(true);`

Added this answer because if someone do a google search for same problem with ListFragment he just finds this..

To store actual Unicode codepoints, you have to first decode the String's UTF-16 codeunits to UTF-32 codeunits (which are currently the same as the Unicode codepoints). Use System.Text.Encoding.UTF32.GetBytes() for that, and then write the resulting bytes to the StringBuilder as needed,i.e.

static void Main(string[] args) 
{ 
    String originalString = "This string contains the unicode character Pi(p)"; 
    Byte[] bytes = Encoding.UTF32.GetBytes(originalString);
    StringBuilder asAscii = new StringBuilder();
    for (int idx = 0; idx < bytes.Length; idx += 4)
    { 
        uint codepoint = BitConverter.ToUInt32(bytes, idx);
        if (codepoint <= 127) 
            asAscii.Append(Convert.ToChar(codepoint)); 
        else 
            asAscii.AppendFormat("\\u{0:x4}", codepoint); 
    } 
    Console.WriteLine("Final string: {0}", asAscii); 
    Console.ReadKey(); 
}

npm module has to be bundeled inside your nodejs package and upload to AWS Lambda Layers as zip, then you would need to refer to your module/js as below and use available methods from it. const mymodule = require('/opt/nodejs/MyLogger');

Use the Random class:

int getRandomNumber(int[] arr)
{
  return arr[(new Random()).nextInt(arr.length)];
}

You can use a tool called gitk.

Two steps worked for me:

gem install bundler

bundle install --redownload # Forces a redownload of all gems on the gemfile, assigning them to the new bundler

Some ideas:

1. Maybe you could simply not inherit from the parent in that case (and declare a dependency on base with the exclusion). Not handy if you have lot of stuff in the parent pom.

2. Another thing to test would be to declare the mail artifact with the version required by ALL-DEPS under the dependencyManagement in the parent pom to force the convergence (although I'm not sure this will solve the scoping problem).

<dependencyManagement>
  <dependencies>
    <dependency>    
      <groupId>javax.mail</groupId>
      <artifactId>mail</artifactId>
      <version>???</version><!-- put the "right" version here -->
    </dependency>
  </dependencies>
</dependencyManagement>

1. Or you could exclude the mail dependency from log4j if you're not using the features relying on it (and this is what I would do):

<dependency>
  <groupId>log4j</groupId>
  <artifactId>log4j</artifactId>
  <version>1.2.15</version>
  <scope>provided</scope>
  <exclusions>
    <exclusion>
      <groupId>javax.mail</groupId>
      <artifactId>mail</artifactId>
    </exclusion>
    <exclusion>
      <groupId>javax.jms</groupId>
      <artifactId>jms</artifactId>
    </exclusion>
    <exclusion>
      <groupId>com.sun.jdmk</groupId>
      <artifactId>jmxtools</artifactId>
    </exclusion>
    <exclusion>
      <groupId>com.sun.jmx</groupId>
      <artifactId>jmxri</artifactId>
    </exclusion>
  </exclusions>
</dependency>

1. Or you could revert to the version 1.2.14 of log4j instead of the heretic 1.2.15 version (why didn't they mark the above dependencies as optional?!).

Note that if you fail to specify a revision then you have to include a separator. Example from my console:

git reset <path_to_file>
fatal: ambiguous argument '<path_to_file>': unknown revision or path not in the working tree.
Use '--' to separate paths from revisions

git reset -- <path_to_file>
Unstaged changes after reset:
M    <path_to_file>

(Git version 1.7.5.4)

The count function is meant to be used on

1. Arrays
2. Objects that are derived from classes that implement the countable interface

A stdClass is neither of these. The easier/quickest way to accomplish what you're after is

$count = count(get_object_vars($some_std_class_object));

This uses PHP's get_object_vars function, which will return the properties of an object as an array. You can then use this array with PHP's count function.

Hey, this one is kind of ugly but it's one line only:

imgTitle.Source = new BitmapImage(new Uri(@"pack://application:,,,/YourAssembly;component/your_image.png"));

In my case I was changing the data previously inside a thread with mRecyclerView.post(new Runnable...) and then again later changed data in the UI thread, which caused inconsistency.

create a hidden iframe, then in your ajax code above:

url: document.getElementById('myiframeid').src = your_server_side_url,

and remove the window.open(response);

You can find current locks on your table by following query.

USE yourdatabase;
GO

SELECT * FROM sys.dm_tran_locks
  WHERE resource_database_id = DB_ID()
  AND resource_associated_entity_id = OBJECT_ID(N'dbo.yourtablename');

See sys.dm_tran_locks

If multiple instances of the same request_owner_type exist, the request_owner_id column is used to distinguish each instance. For distributed transactions, the request_owner_type and the request_owner_guid columns will show the different entity information.

For example, Session S1 owns a shared lock on Table1; and transaction T1, which is running under session S1, also owns a shared lock on Table1. In this case, the resource_description column that is returned by sys.dm_tran_locks will show two instances of the same resource. The request_owner_type column will show one instance as a session and the other as a transaction. Also, the resource_owner_id column will have different values.

To add onto what @Delosdos has posted.

Set a validator for a control in the FormGroup: this.myForm.controls['controlName'].setValidators([Validators.required])

Remove the validator from the control in the FormGroup: this.myForm.controls['controlName'].clearValidators()

Update the FormGroup once you have run either of the above lines. this.myForm.controls['controlName'].updateValueAndValidity()

This is an amazing way to programmatically set your form validation.

use below simple code, no need to use any library

String list = "your_json_string";
Gson gson = new Gson();                         
Type listType = new TypeToken<ArrayList<YourClassObject>>() {}.getType();
ArrayList<YourClassObject> users = new Gson().fromJson(list , listType);

For Power-Shell

./adb shell getprop | Select-String -Pattern '(model)|(version.sdk)|(manufacturer)|(platform)|(serialno)|(product.name)|(brand)'

For linux(burrowing asnwer from @0x8BADF00D)

adb shell getprop | grep "model\|version.sdk\|manufacturer\|hardware\|platform\|revision\|serialno\|product.name\|brand"

For single string find in power shell

./adb shell getprop | Select-String -Pattern 'model'

or

./adb shell getprop | Select-String -Pattern '(model)'

For multiple

./adb shell getprop | Select-String -Pattern '(a|b|c|d)'

The call to InitializeComponent() (which is usually called in the default constructor of at least Window and UserControl) is actually a method call to the partial class of the control (rather than a call up the object hierarchy as I first expected).

This method locates a URI to the XAML for the Window/UserControl that is loading, and passes it to the System.Windows.Application.LoadComponent() static method. LoadComponent() loads the XAML file that is located at the passed in URI, and converts it to an instance of the object that is specified by the root element of the XAML file.

In more detail, LoadComponent creates an instance of the XamlParser, and builds a tree of the XAML. Each node is parsed by the XamlParser.ProcessXamlNode(). This gets passed to the BamlRecordWriter class. Some time after this I get a bit lost in how the BAML is converted to objects, but this may be enough to help you on the path to enlightenment.

Note: Interestingly, the InitializeComponent is a method on the System.Windows.Markup.IComponentConnector interface, of which Window/UserControl implement in the partial generated class.

Hope this helps!

Try this:

#signin input {
    background-color:#FFF;
    height: 1.5em;
    /* or */
    line-height: 1.5em;
}

If you are working with objects track by the identifier(e.g. $index) instead of the whole object and you reload your data later, ngRepeat will not rebuild the DOM elements for items it has already rendered, even if the JavaScript objects in the collection have been substituted for new ones.

You can also set the options --log-fd if you just want to read your logs with a less. For example :

valgrind --log-fd=1 ls | less

Nick has the right answer, but I wanted to add you could also get the cell data without needing the class name

var Something = $(this).closest('tr').find('td:eq(1)').text();

:eq(#) has a zero based index (link).

Even easier:

sysctl -n hw.ncpu

I know this is an old question, but I've just had this with a 3.5 application on my rebuilt Windows 8 machine and I was still getting this after aspnet_regiis -iru and it turned out the be ASP.NET 3.5 wasn't ticked within Application Development Features (not enough reputation to post an image).

NULL stands for a variable without value. To check if a variable is NULL you can either use is_null($var) or the comparison (===) with NULL. Both ways, however, generate a warning if the variable is not defined. Similar to isset($var) and empty($var), which can be used as functions.

var_dump(is_null($var)); // true
var_dump($var === null); // true
var_dump(empty($var)); // true

Read more in How to check if a variable is NULL in PHP?

I saw that the question is already answered, but if you'd like to learn more details, there are a total of 3 cases of communication between components:

• Case 1: Parent to Child communication
• Case 2: Child to Parent communication
• Case 3: Not-related components (any component to any component) communication

There are two reasons you might get this message:

1. ASP.Net is not configured. For this run from Administrator command %FrameworkDir%\%FrameworkVersion%\aspnet_regiis -i. Read the message carefully. On Windows8/IIS8 it may say that this is no longer supported and you may have to use Turn Windows Features On/Off dialog in Install/Uninstall a Program in Control Panel.
2. Another reason this may happen is because your App Pool is not configured correctly. For example, you created website for WordPress and you also want to throw in few aspx files in there, WordPress creates app pool that says don't run CLR stuff. To fix this just open up App Pool and enable CLR.

The solutions using CASE, IIF, and UDF are adequate, but impractical when extending the problem to the general case using more than 2 comparison values. The generalized solution in SQL Server 2008+ utilizes a strange application of the VALUES clause:

SELECT
PaidForPast=(SELECT MIN(x) FROM (VALUES (PaidThisMonth),(OwedPast)) AS value(x))

You need to use

{!! $text !!}

The string will auto escape when using {{ $text }}.

You shouldn't overload the templates with complex logic, it's a bad practice. Remember to always keep it simple!

The better approach would be to extract this logic into reusable function on your $rootScope:

.run(function ($rootScope) {
  $rootScope.inArray = function (item, array) {
    return (-1 !== array.indexOf(item));
  };
})

Then, use it in your template:

<li ng-class="{approved: inArray(jobSet, selectedForApproval)}"></li>

I think everyone will agree that this example is much more readable and maintainable.

The PHP way of doing this is simple:

$out = strlen($in) > 50 ? substr($in,0,50)."..." : $in;

But you can achieve a much nicer effect with this CSS:

.ellipsis {
    overflow: hidden;
    white-space: nowrap;
    text-overflow: ellipsis;
}

Now, assuming the element has a fixed width, the browser will automatically break off and add the ... for you.

We usually use One Main Window for the application and other windows can be used in situations like when you need popups because instead of using popup controls in XAML which are not visible we can use a Window that is visible at design time so that'll be easy to work with

on the other hand we use many pages to navigate from one screen to another like User management screen to Order Screen etc In the main Window we can use Frame control for navigation like below XAML

    <Frame Name="mainWinFrame" NavigationUIVisibility="Hidden"  ButtonBase.Click="mainWinFrame_Click">
    </Frame>

C#

     private void mainWinFrame_Click(object sender, RoutedEventArgs e)
    {
        try
        {
            if (e.OriginalSource is Button)
            {
                Button btn = (Button)e.OriginalSource;

                if ((btn.CommandParameter != null) && (btn.CommandParameter.Equals("Order")))
                {

                    mainWinFrame.Navigate(OrderPage);
                }
            }
        }
        catch (Exception ex)
        {
            MessageBox.Show(ex.Message, "Error");
        }
    }

That's one way of doing it We can also use a Tab Control instead of Fram and Add pages to it using a Dictionary while adding new page check if the control already exists then only navigate otherwise add and navigate. I hope that'll help someone

I would recommend node-cron. It allows to run tasks using Cron patterns e.g.

'* * * * * *' - runs every second
'*/5 * * * * *' - runs every 5 seconds
'10,20,30 * * * * *' - run at 10th, 20th and 30th second of every minute
'0 * * * * *' - runs every minute
'0 0 * * * *' - runs every hour (at 0 minutes and 0 seconds)

But also more complex schedules e.g.

'00 30 11 * * 1-5' - Runs every weekday (Monday through Friday) at 11:30:00 AM. It does not run on Saturday or Sunday.

Sample code: running job every 10 minutes:

var cron = require('cron');
var cronJob = cron.job("0 */10 * * * *", function(){
    // perform operation e.g. GET request http.get() etc.
    console.info('cron job completed');
}); 
cronJob.start();

You can find more examples in node-cron wiki

More on cron configuration can be found on cron wiki

I've been using that library in many projects and it does the job. I hope that will help.

For brew users

If you're using brew like me and wasted a lot of time searching for the infamous kafka-logs folder, fear no more. (and please do let me know if that works for you and multiple different versions of Homebrew, Kafka etc :) )

You're probably going to find it under:

Location:

/usr/local/var/lib/kafka-logs

How to actually find that path

(this is also helpful for basically every app you install through brew)

1) brew services list

kafka started matbhz /Users/matbhz/Library/LaunchAgents/homebrew.mxcl.kafka.plist

2) Open and read that plist you found above

3) Find the line defining server.properties location open it, in my case:

• /usr/local/etc/kafka/server.properties

4) Look for the log.dirs line:

log.dirs=/usr/local/var/lib/kafka-logs

5) Go to that location and delete the logs for the topics you wish

6) Restart Kafka with brew services restart kafka

You may be able to fix this error by name spacing :: the function call

comparison.cloud(colors = c("red", "green"), max.words = 100)

to

wordcloud::comparison.cloud(colors = c("red", "green"), max.words = 100)

I think this will do it for you:

location / {
    try_files /base.html =404;
}

<context:component-scan base-package="" /> 

tells Spring to scan those packages for Annotations.

<mvc:annotation-driven> 

registers a RequestMappingHanderMapping, a RequestMappingHandlerAdapter, and an ExceptionHandlerExceptionResolver to support the annotated controller methods like @RequestMapping, @ExceptionHandler, etc. that come with MVC.

This also enables a ConversionService that supports Annotation driven formatting of outputs as well as Annotation driven validation for inputs. It also enables support for @ResponseBody which you can use to return JSON data.

You can accomplish the same things using Java-based Configuration using @ComponentScan(basePackages={"...", "..."} and @EnableWebMvc in a @Configuration class.

Check out the 3.1 documentation to learn more.

When using a glob pattern, a question mark represents a single character and an asterisk represents a sequence of zero or more characters:

if [[ $gg == ????grid* ]] ; then echo $gg; fi

When using a regular expression, a dot represents a single character and an asterisk represents zero or more of the preceding character. So ".*" represents zero or more of any character, "a*" represents zero or more "a", "[0-9]*" represents zero or more digits. Another useful one (among many) is the plus sign which represents one or more of the preceding character. So "[a-z]+" represents one or more lowercase alpha character (in the C locale - and some others).

if [[ $gg =~ ^....grid.*$ ]] ; then echo $gg; fi

This is specific for each site. So if you type that once, you will only get through that site and all other sites will need a similar type-through.

It is also remembered for that site and you have to click on the padlock to reset it (so you can type it again):

Needless to say use of this "feature" is a bad idea and is unsafe - hence the name.

You should find out why the site is showing the error and/or stop using it until they fix it. HSTS specifically adds protections for bad certs to prevent you clicking through them. The fact it's needed suggests there is something wrong with the https connection - like the site or your connection to it has been hacked.

The chrome developers also do change this periodically. They changed it recently from badidea to thisisunsafe so everyone using badidea, suddenly stopped being able to use it. You should not depend on it. As Steffen pointed out in the comments below, it is available in the code should it change again though they now base64 encode it to make it more obscure. The last time they changed they put this comment in the commit:

Rotate the interstitial bypass keyword

The security interstitial bypass keyword hasn't changed in two years and awareness of the bypass has been increased in blogs and social media. Rotate the keyword to help prevent misuse.

I think the message from the Chrome team is clear - you should not use it. It would not surprise me if they removed it completely in future.

If you are using this when using a self-signed certificate for local testing then why not just add your self-signed certificate certificate to your computer's certificate store so you get a green padlock and do not have to type this? Note Chrome insists on a SAN field in certificates now so if just using the old subject field then even adding it to the certificate store will not result in a green padlock.

If you leave the certificate untrusted then certain things do not work. Caching for example is completely ignored for untrusted certificates. As is HTTP/2 Push.

HTTPS is here to stay and we need to get used to using it properly - and not bypassing the warnings with a hack that is liable to change and doesn't work the same as a full HTTPS solution.

My simplest approach using just angular build-in directive:

ng-keypress, ng-keydown or ng-keyup.

Usually, we want add keyboard support for something that already handled by ng-click.

for instance:

<a ng-click="action()">action</a>

Now, let's add keyboard support.

trigger by enter key:

<a ng-click="action()" 
   ng-keydown="$event.keyCode === 13 && action()">action</a>

by space key:

<a ng-click="action()" 
   ng-keydown="$event.keyCode === 32 && action()">action</a>

by space or enter key:

<a ng-click="action()" 
   ng-keydown="($event.keyCode === 13 || $event.keyCode === 32) && action()">action</a>

if you are in modern browser

<a ng-click="action()" 
   ng-keydown="[13, 32].includes($event.keyCode) && action()">action</a>

More about keyCode:
keyCode is deprecated but well supported API, you could use $evevt.key in supported browser instead.

You could use PHP's dirname function. <?php echo dirname(__DIR__); ?>. That will give you the name of the parent directory of __DIR__, which stores the current directory.

GetCursorPos() will return to you the x/y if you pass in a pointer to a POINT structure.

Hiding the cursor can be done with ShowCursor().

Worth to note, you will probably use those lots more than in similar concepts in relational world (composite keys).

Example - suppose you have to find last N users who recently joined user group X. How would you do this efficiently given reads are predominant in this case? Like that (from offical Cassandra guide):

CREATE TABLE group_join_dates (
    groupname text,
    joined timeuuid,
    join_date text,
    username text,
    email text,
    age int,
    PRIMARY KEY ((groupname, join_date), joined)
) WITH CLUSTERING ORDER BY (joined DESC)

Here, partitioning key is compound itself and the clustering key is a joined date. The reason why a clustering key is a join date is that results are already sorted (and stored, which makes lookups fast). But why do we use a compound key for partitioning key? Because we always want to read as few partitions as possible. How putting join_date in there helps? Now users from the same group and the same join date will reside in a single partition! This means we will always read as few partitions as possible (first start with the newest, then move to older and so on, rather than jumping between them).

In fact, in extreme cases you would also need to use the hash of a join_date rather than a join_date alone - so that if you query for last 3 days often those share the same hash and therefore are available from same partition!

A NULL pointer points to memory that doesn't exist, and will raise Segmentation fault. There's an easier way to de-reference a NULL pointer, take a look.

int main(int argc, char const *argv[])
{
    *(int *)0 = 0; // Segmentation fault (core dumped)
    return 0;
}

Since 0 is never a valid pointer value, a fault occurs.

SIGSEGV {si_signo=SIGSEGV, si_code=SEGV_MAPERR, si_addr=NULL}

When I pass a little complex DOM query to $._data like this: $._data($('#outerWrap .innerWrap ul li:last a'), 'events') it throws undefined in the browser console.

So I had to use $._data on the parent div: $._data($('#outerWrap')[0], 'events') to see the events for the a tags. Here is a JSFiddle for the same: http://jsfiddle.net/giri_jeedigunta/MLcpT/4/

maytham-???i???, you can use this code to simulate input of file:

System.setIn(new FileInputStream("FILE_NAME"));

Or send file name as parameter and then put it into FileInputStream:

System.setIn(new FileInputStream(args[0]));

With ES6 you can simply do:

 for(const element of Results) {
      element.Active = "false";
 }

Create a Date object using the diffence between your times as a constructor,
then use Calendar methods to get values ..

Date diff = new Date(d2.getTime() - d1.getTime());

Calendar calendar = Calendar.getInstance();
calendar.setTime(diff);
int hours = calendar.get(Calendar.HOUR_OF_DAY);
int minutes = calendar.get(Calendar.MINUTE);
int seconds = calendar.get(Calendar.SECOND);

This will delete all the merged local branched except local master reference and the one currently being used:

git branch --merged | grep -v "*" | grep -v "master" | xargs git branch -d

And this will delete all the branches having already been removed from the remote repository referenced by "origin", but are still locally available in "remotes/origin".

git remote prune origin

Autofac. https://github.com/autofac/Autofac It is really fast and pretty good. Here is a link with comparisons (made after Ninject fixed a memory leak issue).

You have to read the data too.

Check out : http://www.doughellmann.com/PyMOTW/urllib2/ to understand it.

response = urllib2.urlopen(..)
headers = response.info()
data = response.read()

Of course, what you want is to render it in browser and aaronasterling's answer is what you want.

in addition to the options shown in your question, there is the possibility of implementing the action directly in your xml file from the menu, for example:

<item
   android:id="@+id/OK_MENU_ITEM"
   android:onClick="showMsgDirectMenuXml" />

And for your Java (Activity) file, you need to implement a public method with a single parameter of type MenuItem, for example:

 private void showMsgDirectMenuXml(MenuItem item) {
    Toast toast = Toast.makeText(this, "OK", Toast.LENGTH_LONG);
    toast.show();
  }

NOTE: This method will have behavior similar to the onOptionsItemSelected (MenuItem item)

I think what he is trying to say is to use the getContentPane().setBackground(Color.the_Color_you_want_here)

but if u want to set the color to any other then the JFrame, you use the object.setBackground(Color.the_Color_you_want_here)

Eg:

jPanel.setbackground(Color.BLUE)

Technically ECMAScript is the language that everyone is using and implementing -- it is the specification created many years ago when Netscape and Microsoft sat down and attempted to standardise the scripting between JavaScript (Netscape's scripting language) and JScript (Microsoft's).

Subsequently all these engines are ostensibly implementing ECMAScript, however JavaScript (the name) now hangs around for both traditional naming reasons, and as a marketing term by Mozilla for their various non-standard extensions (which they want to be able to actually "version")

If you do "git status" while having a merge conflict, the first thing git shows you is how to abort the merge.

We've solved this, although we didn't think having the addListener outside of the for would make any difference, it seems to. Here's the answer:

Create a new function with your information for the infoWindow in it:

function addInfoWindow(marker, message) {

            var infoWindow = new google.maps.InfoWindow({
                content: message
            });

            google.maps.event.addListener(marker, 'click', function () {
                infoWindow.open(map, marker);
            });
        }

Then call the function with the array ID and the marker you want to create:

addInfoWindow(marker, hotels[i][3]);

I would say Ruby is slow because not much effort has been spent in making the interpreter faster. Same applies to Python. Smalltalk is just as dynamic as Ruby or Python but performs better by a magnitude, see http://benchmarksgame.alioth.debian.org. Since Smalltalk was more or less replaced by Java and C# (that is at least 10 years ago) no more performance optimization work had been done for it and Smalltalk is still ways faster than Ruby and Python. The people at Xerox Parc and at OTI/IBM had the money to pay the people that work on making Smalltalk faster. What I don't understand is why Google doesn't spend the money for making Python faster as they are a big Python shop. Instead they spend money on development of languages like Go...

Check the apache User and Group setting in the httpd.conf. It should default to apache on AMI/RedHat or www-data on Debian.

grep '^Group\|^User' /etc/httpd/conf/httpd.conf

Then add the apache user to the group setting of your site's root directory.

sudo usermod -a -G <your-site-root-dir-group> apache

I had a problem with my AndroidManifest.xml file and the R.java was not generated.

I think the solution is to check ALL of your XML files, everywhere!

I have always gotten away with the following hack to get it to work with css only.

padding-left: 45%;
font-size: 50px;

padding will center the text and can be tweaked for the text size :)

This is obviously not 100% correct from a validation point of view I guess but it does the job :)

I was facing the same issue but I switched 26.0.0-beta1 dependencies to 26.1.0 and it's working now.

If the user is interacting with another application, it may not be possible to bring yours to the front. As a general rule, a process can only expect to set the foreground window if that process is already the foreground process. (Microsoft documents the restrictions in the SetForegroundWindow() MSDN entry.) This is because:

1. The user "owns" the foreground. For example, it would be extremely annoying if another program stole the foreground while the user is typing, at the very least interrupting her workflow, and possibly causing unintended consequences as her keystrokes meant for one application are misinterpreted by the offender until she notices the change.
2. Imagine that each of two programs checks to see if its window is the foreground and attempts to set it to the foreground if it is not. As soon as the second program is running, the computer is rendered useless as the foreground bounces between the two at every task switch.

SQL Server DateDiff

SELECT DATEDIFF(day, @startdate, @enddate);

On iOS there is the switch UI component instead of a checkbox, look into the UISwitch class. The property on (boolean) can be used to determine the state of the slider and about the saving of its state: That depends on how you save your other stuff already, its just saving a boolean value.

Following code works well, and each column has same width:

public class GridSpacingItemDecoration extends RecyclerView.ItemDecoration {

    private int spanCount;
    private int spacing;
    private boolean includeEdge;

    public GridSpacingItemDecoration(int spanCount, int spacing, boolean includeEdge) {
        this.spanCount = spanCount;
        this.spacing = spacing;
        this.includeEdge = includeEdge;
    }

    @Override
    public void getItemOffsets(Rect outRect, View view, RecyclerView parent, RecyclerView.State state) {
        int position = parent.getChildAdapterPosition(view); // item position
        int column = position % spanCount; // item column

        if (includeEdge) {
            outRect.left = spacing - column * spacing / spanCount; // spacing - column * ((1f / spanCount) * spacing)
            outRect.right = (column + 1) * spacing / spanCount; // (column + 1) * ((1f / spanCount) * spacing)

            if (position < spanCount) { // top edge
                outRect.top = spacing;
            }
            outRect.bottom = spacing; // item bottom
        } else {
            outRect.left = column * spacing / spanCount; // column * ((1f / spanCount) * spacing)
            outRect.right = spacing - (column + 1) * spacing / spanCount; // spacing - (column + 1) * ((1f /    spanCount) * spacing)
            if (position >= spanCount) {
                outRect.top = spacing; // item top
            }
        }
    }
}

Usage

1. no edge

int spanCount = 3; // 3 columns
int spacing = 50; // 50px
boolean includeEdge = false;
recyclerView.addItemDecoration(new GridSpacingItemDecoration(spanCount, spacing, includeEdge));

2. with edge

int spanCount = 3; // 3 columns
int spacing = 50; // 50px
boolean includeEdge = true;
recyclerView.addItemDecoration(new GridSpacingItemDecoration(spanCount, spacing, includeEdge));

I had the same problem. Restart did not work for me. There was a process called VBSCompiler was running in task manager. I had to end the process to fix this error.

Use raw:

But as @jmort253 correctly says, consider where the HTML really belongs.

Use the phpinfo(); function to see the table of settings on your browser and look for the

Configuration File (php.ini) Path

and edit that file. Your computer can have multiple php.ini files, you want to edit the right one.

Also check display_errors = On, html_errors = On and error_reporting = E_ALL inside that file

Restart Apache.

Check the android path of the emulator.

I had to change the registry in here:

 HKEY_LOCAL_MACHINE > SOFTWARE > WOW6432Node > Android SDK Tools

to the actual path of the sdk location (which can be found in android studio: settings-> System Settings -> Android SDK)

Add this code in your project level build.gradle file.

subprojects {
    project.configurations.all {
        resolutionStrategy.eachDependency { details ->
            if (details.requested.group == 'com.android.support'
                    && !details.requested.name.contains('multidex') ) {
                details.useVersion "version which should be used - in your case 28.0.0-beta2"
            }
        }
    }
}

Sample Code :

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {

    repositories {
        google()
        jcenter()
        maven { url 'https://maven.fabric.io/public' }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.0'
        classpath 'io.fabric.tools:gradle:1.31.0'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files

    }
}

allprojects {
    repositories {
        google()
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}


subprojects {
    project.configurations.all {
        resolutionStrategy.eachDependency { details ->
            if (details.requested.group == 'com.android.support'
                    && !details.requested.name.contains('multidex') ) {
                details.useVersion "28.0.0"
            }
        }
    }
}

It's hard to tell without looking at the full code but this type of error

Uncaught TypeError: $(...).slick is not a function

Usually means that you either forgot to include slick.js in the page or you included it before jquery.

Make sure jquery is the first js file and you included the slick.js library after it.

I encountered this issue with entity framework when typing migration commands in Nuget console.

the problem showed up when I moved my OAuthAuthorizationServerProvider codes from my application into a class library project which contained core data access logic as well as my DBContext class.

I check all my DLLs referenced by the class library project. and for all of them (except .net system DLLs) CopyToLocal was true I was completely confused.

I knew that there was something wrong with DLLs themselves not my codes. I checked them again and I noticed that when I moved my ApplicationOauthProvider class into a class library project the ApplicationOauthProvider inherits from OAuthAuthorizationServerProvider class which is located in Microsoft.Owin.Security.OAuth assembly, I checked it's package version and suddenly noticed that the version of package that I used for the class library project (not my application project) is very old 2.1, but on my application the latest version was installed (3.0.1) so I upgraded version of the Microsoft.Owin.Security.OAuth package from Nuget fo my class library project and problem got away

In short after checking CopyToLocal property of your DLLs check their versions too and update the old ones to letest version

Easiest way to make multiline strings in Javascrips is with the use of backticks ( `` ). This allows you to create multiline strings in which you can insert variables with ${variableName}.

Example:

let name = 'Willem'; _x000D_
let age = 26;_x000D_
_x000D_
let multilineString = `_x000D_
my name is: ${name}_x000D_
_x000D_
my age is: ${age}_x000D_
`;_x000D_
_x000D_
console.log(multilineString);

• It was introduces in ES6//es2015
• It is now natively supported by all major browser vendors (except internet explorer)

Just another way to do this:

=MID(A1, LEN(A1), 1)

You can use .gitignore in the top level to ignore all directories in the project with the same name. For example:

Debug/
Release/

This should update immediately so it's visible when you do git status. Ensure that these directories are not already added to git, as that will override the ignores.

For security reasons most browsers do not allow to modify the clipboard (except IE, of course...).

The only way to make a copy-to-clipboard function cross-browser compatible is to use Flash.

<form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>"> <!-- notice the updated action -->
<textarea cols="30" rows="4" name="update" id="update" maxlength="200" ></textarea>
<br />
<input name="submit_button" type="submit"  value=" Update "  id="update_button"  class="update_button"/> <!-- notice added name="" -->
</form>

on your full page, you could have this

<?php

// check if the form was submitted
if ($_POST['submit_button']) {
    // this means the submit button was clicked, and the form has refreshed the page
    // to access the content in text area, you would do this
    $a = $_POST['update'];

    // now $a contains the data from the textarea, so you can do whatever with it
    // this will echo the data on the page
    echo $a;
}
else {
    // form not submitted, so show the form

?>

<form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>"> <!-- notice the updated action -->
<textarea cols="30" rows="4" name="update" id="update" maxlength="200" ></textarea>
<br />
<input name="submit_button" type="submit"  value=" Update "  id="update_button"  class="update_button"/> <!-- notice added name="" -->
</form>

<?php

} // end "else" loop

?>

I'm still not convinced that Hyper-V is The Thing for me, even with last year's Docker trials and tribulations and I guess you won't want to switch very frequently, so rather than creating a new boot and confirming the boot default or waiting out the timeout with every boot I switch on demand in the console in admin mode by

bcdedit /set hypervisorlaunchtype off

Another reason for this post -- to save you some headache: You thought you switch Hyper-V on with the "on" argument again? Nope. Too simple for MiRKoS..t. It's auto!

All your problems derive from this

byte[] encrypted = cipher.doFinal(toEncrypt.getBytes());
return encrypted;

Which are enclosed in a try, catch block, the problem is that in case the program found an exception you are not returning anything. Put it like this (modify it as your program logic stands):

public static byte[] encrypt(String toEncrypt) throws Exception{
    try{
        String plaintext = toEncrypt;
        String key = "01234567890abcde";
        String iv = "fedcba9876543210";

        SecretKeySpec keyspec = new SecretKeySpec(key.getBytes(), "AES");
        IvParameterSpec ivspec = new IvParameterSpec(iv.getBytes());

        Cipher cipher = Cipher.getInstance("AES/CBC/NoPadding");
        cipher.init(Cipher.ENCRYPT_MODE,keyspec,ivspec);
        byte[] encrypted = cipher.doFinal(toEncrypt.getBytes());

        return encrypted;
    } catch(Exception e){
        return null;            // Always must return something
    }
}

For the second one you must catch the Exception from the encrypt method call, like this (also modify it as your program logic stands):

public void actionPerformed(ActionEvent e)
  .
  .
  .
    try {
        byte[] encrypted = encrypt(concatURL);
        String encryptedString = bytesToHex(encrypted);
        content.removeAll();
        content.add(new JLabel("Concatenated User Input -->" + concatURL));

        content.add(encryptedTextField);
    setContentPane(content);
    } catch (Exception exc) {
        // TODO: handle exception
    }
}

The lessons you must learn from this:

• A method with a return-type must always return an object of that type, I mean in all possible scenarios
• All checked exceptions must always be handled

Alliteratively you can try placing a Label control and placing it on top of the progress bar control. Then you can set whatever the text you want to the label. I haven't done this my self. If it works it should be a simpler solution than overriding onpaint.

Personally, I like to use named entities when they are available, because they make my HTML more readable. Because of that, I like to use ✓ for ✓ and ✗ for ✗. If you're not sure whether a named entity exists for the character you want, try the &what search site. It includes the name for each entity, if there is one.

As mentioned in the comments, ✓ and ✗ are not supported in HTML4, so you may be better off using the more cryptic ✓ and ✗ if you want to target the most browsers. The most definitive references I could find were on the W3C site: HTML4 and HTML5.

You should be pointing it towards the Developer directory, not the Xcode application bundle. Run this:

sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer

With recent versions of Xcode, you can go to Xcode ? Preferences… ? Locations and pick one of the options for Command Line Tools to set the location.

Assuming that ID is an identity column:

INSERT INTO TheTable(HospitalID, Email, Description)
SELECT 32, Email, Description FROM TheTable
WHERE HospitalID <> 32

Try to avoid loops with SQL. Try to think in terms of sets instead.

To get around sandboxing of SCM stored Groovy scripts, I recommend to run the script as Groovy Command (instead of Groovy Script file):

import hudson.FilePath
final GROOVY_SCRIPT = "workspace/relative/path/to/the/checked/out/groovy/script.groovy"

evaluate(new FilePath(build.workspace, GROOVY_SCRIPT).read().text)

in such case, the groovy script is transferred from the workspace to the Jenkins Master where it can be executed as a system Groovy Script. The sandboxing is suppressed as long as the Use Groovy Sandbox is not checked.

You can change the default location of .m2 directory in m2.conf file. It resides in your maven installation directory.

add modify this line in

m2.conf

set maven.home C:\Users\me\.m2

And yet another option: https://github.com/apptik/jus

• It is modular like Volley, but more extended and documentation is improving, supporting different HTTP stacks and converters out of the box
• It has a module to generate server API interface mappings like Retrofit
• It also has JavaRx support

And many other handy features like markers, transformers, etc.

Yes, you could make an indexer on your Record class that maps from the property name to the correct property. This would keep all the binding from property name to property in one place eg:

public class Record
{
    public string ItemType { get; set; }

    public string this[string propertyName]
    {
        set
        {
            switch (propertyName)
            {
                case "itemType":
                    ItemType = value;
                    break;
                    // etc
            }   
        }
    }
}

Alternatively, as others have mentioned, use reflection.

I changed '\n' for chr(10) and it worked:

$pdf->MultiCell(0,5,utf8_decode($variable1 . chr(10) . $variable2),1);

It is the same construct - simply test for empty strings rather than NA:

Try this:

df <- df[-which(df$start_pc == ""), ]

In fact, looking at your code, you don't need the which, but use the negation instead, so you can simplify it to:

df <- df[!(df$start_pc == ""), ]
df <- df[!is.na(df$start_pc), ]

And, of course, you can combine these two statements as follows:

df <- df[!(df$start_pc == "" | is.na(df$start_pc)), ]

And simplify it even further with with:

df <- with(df, df[!(start_pc == "" | is.na(start_pc)), ])

You can also test for non-zero string length using nzchar.

df <- with(df, df[!(nzchar(start_pc) | is.na(start_pc)), ])

Disclaimer: I didn't test any of this code. Please let me know if there are syntax errors anywhere

According to the stack trace, your issue is that your app cannot find org.apache.commons.dbcp.BasicDataSource, as per this line:

java.lang.ClassNotFoundException: org.apache.commons.dbcp.BasicDataSource

I see that you have commons-dbcp in your list of jars, but for whatever reason, your app is not finding the BasicDataSource class in it.

I was having a similar problem. I wanted the selected text to end up in a command, but not rely on pasting it in. Here's the command I was trying to write a mapping for:

:call VimuxRunCommand("python")

The docs for this plugin only show using string literals. The following will break if you try to select text that contains doublequotes:

vnoremap y:call VimuxRunCommand("<c-r>"")<cr>

To get around this, you just reference the contents of the macro using @ :

vnoremap y:call VimuxRunCommand(@")<cr>

Passes the contents of the unnamed register in and works with my double quote and multiline edgecases.

I'd do this:

1. add the dependency as you like in your pom:

   <dependency>
           <groupId>com.stackoverflow...</groupId>
           <artifactId>artifactId...</artifactId>
           <version>1.0</version>
   </dependency>
   

2. run mvn install it will try to download the jar and fail. On the process, it will give you the complete command of installing the jar with the error message. Copy that command and run it! easy huh?!

I faced the same issue regarding apt-get: command not found here are the steps how I resolved it on ubuntu xenial

• Search the appropriate version of apt from here (apt_1.4_amd64.deb for ubuntu xenial)

• Download the apt.deb

  wget http://security.ubuntu.com/ubuntu/pool/main/a/apt/apt_1.4_amd64.deb

• Install the apt.deb package

  sudo dpkg -i apt_1.4_amd64.deb

Now we can easily run

sudo apt-get install htop

You almost had it with Not. It should be:

if (-Not (Test-Path C:\Code)) {
    write "it doesn't exist!"
} 

You can also use !: if (!(Test-Path C:\Code)){}

Just for fun, you could also use bitwise exclusive or, though it's not the most readable/understandable method.

if ((test-path C:\code) -bxor 1) {write "it doesn't exist!"}

In Typescript - app.component.ts file

export class AppComponent implements OnInit {
    currentDate = new Date();
}

In HTML Input field

<input id="form21_1" type="text" tabindex="28" title="DATE" [ngModel]="currentDate | date:'MM/dd/yyyy'" />

It will display the current date inside the input field.

You could do this using ANSI escape sequences. I've actually put together this class in Java for anyone that would like a simple workaround for this. It allows for more than just color codes.

Example Use:

StringBuilder sb = new StringBuilder();

System.out.println(
    sb.raw("Hello, ")
      .underline("John Doe")
      .resetUnderline()
      .raw(". ")
      .raw("This is ")
      .color16(StringBuilder.Color16.FG_RED, "red")
      .raw(".")
);

Subject is the certificate's common name and is a critical property for the certificate in a lot of cases if it's a server certificate and clients are looking for a positive identification.

As an example on an SSL certificate for a web site the subject would be the domain name of the web site.

As Charles Duffey has stated, XML parsers are best parsed with a proper XML parsing tools. For one time job the following should work.

grep -oPm1 "(?<=<title>)[^<]+"

Test:

$ echo "$data"
<item> 
  <title>15:54:57 - George:</title>
  <description>Diane DeConn? You saw Diane DeConn!</description> 
</item> 
<item> 
  <title>15:55:17 - Jerry:</title> 
  <description>Something huh?</description>
$ title=$(grep -oPm1 "(?<=<title>)[^<]+" <<< "$data")
$ echo "$title"
15:54:57 - George:

To pass a string to the view as the Model, you can do:

public ActionResult Index()
{
    string myString = "This is my string";
    return View((object)myString);
}

You must cast it to an object so that MVC doesn't try to load the string as the view name, but instead pass it as the model. You could also write:

return View("Index", myString);

.. which is a bit more verbose.

Then in your view, just type it as a string:

@model string

<p>Value: @Model</p>

Then you can manipulate Model how you want.

For accessing it from a Layout page, it might be better to create an HtmlExtension for this:

public static string GetThemePath(this HtmlHelper helper)
{
    return "/path-to-theme";
}

Then inside your layout page:

<p>Value: @Html.GetThemePath()</p>

Hopefully you can apply this to your own scenario.

Edit: explicit HtmlHelper code:

namespace <root app namespace>
{
    public static class Helpers
    {
        public static string GetThemePath(this HtmlHelper helper)
        {
            return System.Web.Hosting.HostingEnvironment.MapPath("~") + "/path-to-theme";
        }
    }
}

Then in your view:

@{
    var path = Html.GetThemePath();
    // .. do stuff
}

Or: <p>Path: @Html.GetThemePath()</p>

Edit 2:

As discussed, the Helper will work if you add a @using statement to the top of your view, with the namespace pointing to the one that your helper is in.

In python: help(my_list.append) for example, will give you the docstring of the function.

>>> my_list = []
>>> help(my_list.append)

    Help on built-in function append:

    append(...)
        L.append(object) -- append object to end

Try this:

if (MessageBox.Show("Are you sure", "Title_here", MessageBoxButton.YesNo) == MessageBoxResult.Yes)
{
    Do something here for 'Yes'...
}

The most safe way is probably overriding keys method that is used to generate output:

new JSONObject(){
  @Override
  public Iterator keys(){
    TreeSet<Object> sortedKeys = new TreeSet<Object>();
    Iterator keys = super.keys();
    while(keys.hasNext()){
      sortedKeys.add(keys.next());
    }
    return sortedKeys.iterator();
  }
};

In latest version (1.0RC) of TypeScript, you can use enums like this:

enum States {
    New,
    Active,
    Disabled
} 

// this will show message '0' which is number representation of enum member
alert(States.Active); 

// this will show message 'Disabled' as string representation of enum member
alert(States[States.Disabled]);

Update 1

To get number value of enum member from string value, you can use this:

var str = "Active";
// this will show message '1'
alert(States[str]);

Update 2

In latest TypeScript 2.4, there was introduced string enums, like this:

enum ActionType {
    AddUser = "ADD_USER",
    DeleteUser = "DELETE_USER",
    RenameUser = "RENAME_USER",

    // Aliases
    RemoveUser = DeleteUser,
}

For more info about TypeScript 2.4, read blog on MSDN.

Conditional Welcome Message

echo 'Welcome '.($user['is_logged_in'] ? $user['first_name'] : 'Guest').'!';

Nested PHP Shorthand

echo 'Your score is:  '.($score > 10 ? ($age > 10 ? 'Average' : 'Exceptional') : ($age > 10 ? 'Horrible' : 'Average') );

df[df$aged <= df$laclen, ] 

Should do the trick. The square brackets allow you to index based on a logical expression.

Try using getTime (mdn doc) :

var diff = Math.abs(date1.getTime() - date2.getTime()) / 3600000;
if (diff < 18) { /* do something */ }

Using Math.abs() we don't know which date is the smallest. This code is probably more relevant :

var diff = (date1 - date2) / 3600000;
if (diff < 18) { array.push(date1); }

Can unsigned long int hold a ten digits number (1,000,000,000 - 9,999,999,999) on a 32-bit computer.

No

Update: If you are using Angular 1.2+, use ng-repeat-start. See @jmagnusson's answer.

Otherwise, how about putting the ng-repeat on tbody? (AFAIK, it is okay to have multiple <tbody>s in a single table.)

<tbody ng-repeat="row in array">
  <tr ng-repeat="item in row">
     <td>{{item}}</td>
  </tr>
</tbody>

1. first delete the file (project).
2. then rm -rf \Users\Indrajith.E\AppData\Roaming\npm-cache_logs\2019-08-22T08_41_00_271Z-debug.log (this is the file(log) which is showing error).
3. recreate your project for example :- npx create-react-app hello_world
4. then cd hello_world.
5. then npm start.

I was also having this same error but hopefully after spending 1 day on this error i have got this solution and it got started perfectly and i also hope this works for you guys also...

Just surfed in from the web and felt I could contribute. I noticed that with the above code posted by @calethebrewer can result in multiple calls over the selector and unexpected behaviour for example: -

$(document).on('mouseover', '.selector', function() {
   //do something
});
$(document).on('mouseout', '.selector', function() {
   //do something
});

This fiddle http://jsfiddle.net/TWskH/12/ illustraits my point. When animating elements such as in plugins I have found that these multiple triggers result in unintended behavior which may result in the animation or code being called more than is necessary.

My suggestion is to simply replace with mouseenter/mouseleave: -

$(document).on('mouseenter', '.selector', function() {
   //do something
});
$(document).on('mouseleave', '.selector', function() {
   //do something
});

Although this prevented multiple instances of my animation from being called, I eventually went with mouseover/mouseleave as I needed to determine when children of the parent were being hovered over.

You can also directly get selected value using following code

 <select ng-options='t.name for t in templates'
                  ng-change='selectedTemplate(t.url)'></select>

script.js

 $scope.selectedTemplate = function(pTemplate) {
    //Your logic
    alert('Template Url is : '+pTemplate);
}

Gilean's answer is great, but I just wanted to add that sometimes there are rare exceptions to best practices, and you might want to test your environment both ways to see what will work best.

In one case, I found that query worked faster for my purposes because I was bulk transferring trusted data from an Ubuntu Linux box running PHP7 with the poorly supported Microsoft ODBC driver for MS SQL Server.

I arrived at this question because I had a long running script for an ETL that I was trying to squeeze for speed. It seemed intuitive to me that query could be faster than prepare & execute because it was calling only one function instead of two. The parameter binding operation provides excellent protection, but it might be expensive and possibly avoided if unnecessary.

Given a couple rare conditions:

1. If you can't reuse a prepared statement because it's not supported by the Microsoft ODBC driver.

2. If you're not worried about sanitizing input and simple escaping is acceptable. This may be the case because binding certain datatypes isn't supported by the Microsoft ODBC driver.

3. PDO::lastInsertId is not supported by the Microsoft ODBC driver.

Here's a method I used to test my environment, and hopefully you can replicate it or something better in yours:

To start, I've created a basic table in Microsoft SQL Server

CREATE TABLE performancetest (
    sid INT IDENTITY PRIMARY KEY,
    id INT,
    val VARCHAR(100)
);

And now a basic timed test for performance metrics.

$logs = [];

$test = function (String $type, Int $count = 3000) use ($pdo, &$logs) {
    $start = microtime(true);
    $i = 0;
    while ($i < $count) {
        $sql = "INSERT INTO performancetest (id, val) OUTPUT INSERTED.sid VALUES ($i,'value $i')";
        if ($type === 'query') {
            $smt = $pdo->query($sql);
        } else {
            $smt = $pdo->prepare($sql);
            $smt ->execute();
        }
        $sid = $smt->fetch(PDO::FETCH_ASSOC)['sid'];
        $i++;
    }
    $total = (microtime(true) - $start);
    $logs[$type] []= $total;
    echo "$total $type\n";
};

$trials = 15;
$i = 0;
while ($i < $trials) {
    if (random_int(0,1) === 0) {
        $test('query');
    } else {
        $test('prepare');
    }
    $i++;
}

foreach ($logs as $type => $log) {
    $total = 0;
    foreach ($log as $record) {
        $total += $record;
    }
    $count = count($log);
    echo "($count) $type Average: ".$total/$count.PHP_EOL;
}

I've played with multiple different trial and counts in my specific environment, and consistently get between 20-30% faster results with query than prepare/execute

5.8128969669342 prepare
5.8688418865204 prepare
4.2948560714722 query
4.9533629417419 query
5.9051351547241 prepare
4.332102060318 query
5.9672858715057 prepare
5.0667371749878 query
3.8260300159454 query
4.0791549682617 query
4.3775160312653 query
3.6910600662231 query
5.2708210945129 prepare
6.2671611309052 prepare
7.3791449069977 prepare
(7) prepare Average: 6.0673267160143
(8) query Average: 4.3276024162769

I'm curious to see how this test compares in other environments, like MySQL.

This does it in text.

<p> The download will begin in <span id="countdowntimer">10 </span> Seconds</p>_x000D_
_x000D_
<script type="text/javascript">_x000D_
    var timeleft = 10;_x000D_
    var downloadTimer = setInterval(function(){_x000D_
    timeleft--;_x000D_
    document.getElementById("countdowntimer").textContent = timeleft;_x000D_
    if(timeleft <= 0)_x000D_
        clearInterval(downloadTimer);_x000D_
    },1000);_x000D_
</script>

Another method for Swift (without using NSString):

let percentage = 33.3333
let text = String.localizedStringWithFormat("%.02f %@", percentage, "%")

P.S. this solution is not working with CGFloat type only tested with Float & Double

You can use QTextCodec to convert the bytearray to a string:

QString DataAsString = QTextCodec::codecForMib(1015)->toUnicode(Data);

(1015 is UTF-16, 1014 UTF-16LE, 1013 UTF-16BE, 106 UTF-8)

From your example we can see that the string "test" is encoded as "t\0 e\0 s\0 t\0 \0 \0" in your encoding, i.e. every ascii character is followed by a \0-byte, or resp. every ascii character is encoded as 2 bytes. The only unicode encoding in which ascii letters are encoded in this way, are UTF-16 or UCS-2 (which is a restricted version of UTF-16), so in your case the 1015 mib is needed (assuming your local endianess is the same as the input endianess).

Thank you very much! Finally I solved the blurred pixels problem with this code:

<canvas id="graph" width=326 height=240 style='width:326px;height:240px'></canvas>

With the addition of the 'half-pixel' does the trick to unblur lines.

Here is Simple Solution And Complete Example for Uploading File Using Volley Android

1) Gradle Import

compile 'dev.dworks.libs:volleyplus:+'

2)Now Create a Class RequestManager

public class RequestManager {
    private static RequestManager mRequestManager;
    /**
     * Queue which Manages the Network Requests :-)
     */
    private static RequestQueue mRequestQueue;
    // ImageLoader Instance

    private RequestManager() {

    }

    public static RequestManager get(Context context) {

        if (mRequestManager == null)
            mRequestManager = new RequestManager();

        return mRequestManager;
    }

    /**
     * @param context application context
     */
    public static RequestQueue getnstance(Context context) {

        if (mRequestQueue == null) {
            mRequestQueue = Volley.newRequestQueue(context);
        }

        return mRequestQueue;

    }


}

3)Now Create a Class to handle Request for uploading File WebService

public class WebService {
    private RequestQueue mRequestQueue;
    private static WebService apiRequests = null;

    public static WebService getInstance() {
        if (apiRequests == null) {
            apiRequests = new WebService();
            return apiRequests;
        }
        return apiRequests;
    }
    public void updateProfile(Context context, String doc_name, String doc_type, String appliance_id, File file, Response.Listener<String> listener, Response.ErrorListener errorListener) {
        SimpleMultiPartRequest request = new SimpleMultiPartRequest(Request.Method.POST, "YOUR URL HERE", listener, errorListener);
//        request.setParams(data);
        mRequestQueue = RequestManager.getnstance(context);
        request.addMultipartParam("token", "text", "tdfysghfhsdfh");
        request.addMultipartParam("parameter_1", "text", doc_name);
        request.addMultipartParam("dparameter_2", "text", doc_type);
        request.addMultipartParam("parameter_3", "text", appliance_id);
            request.addFile("document_file", file.getPath());

        request.setFixedStreamingMode(true);
        mRequestQueue.add(request);
    }
}

4) And Now Call The method Like This to Hit the service

public class Main2Activity extends AppCompatActivity implements Response.ErrorListener, Response.Listener<String>{

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main2);
        Button button=(Button)findViewById(R.id.button);
        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                uploadData();
            }
        });
    }

    private void uploadData() {
        WebService.getInstance().updateProfile(getActivity(), "appl_doc", "appliance", "1", mChoosenFile, this, this);
    }

    @Override
    public void onErrorResponse(VolleyError error) {

    }

    @Override
    public void onResponse(String response) {
     //Your response here

I downloaded msvcr120d.dll and msvcp120d.dll for 32-bit version and then, I put them into Debug folder of my project. It worked well. (My computer is 64-bit version)

Your @POST method should be accepting a JSON object instead of a string. Jersey uses JAXB to support marshaling and unmarshaling JSON objects (see the jersey docs for details). Create a class like:

@XmlRootElement
public class MyJaxBean {
    @XmlElement public String param1;
    @XmlElement public String param2;
}

Then your @POST method would look like the following:

@POST @Consumes("application/json")
@Path("/create")
public void create(final MyJaxBean input) {
    System.out.println("param1 = " + input.param1);
    System.out.println("param2 = " + input.param2);
}

This method expects to receive JSON object as the body of the HTTP POST. JAX-RS passes the content body of the HTTP message as an unannotated parameter -- input in this case. The actual message would look something like:

POST /create HTTP/1.1
Content-Type: application/json
Content-Length: 35
Host: www.example.com

{"param1":"hello","param2":"world"}

Using JSON in this way is quite common for obvious reasons. However, if you are generating or consuming it in something other than JavaScript, then you do have to be careful to properly escape the data. In JAX-RS, you would use a MessageBodyReader and MessageBodyWriter to implement this. I believe that Jersey already has implementations for the required types (e.g., Java primitives and JAXB wrapped classes) as well as for JSON. JAX-RS supports a number of other methods for passing data. These don't require the creation of a new class since the data is passed using simple argument passing.

HTML <FORM>

The parameters would be annotated using @FormParam:

@POST
@Path("/create")
public void create(@FormParam("param1") String param1,
                   @FormParam("param2") String param2) {
    ...
}

The browser will encode the form using "application/x-www-form-urlencoded". The JAX-RS runtime will take care of decoding the body and passing it to the method. Here's what you should see on the wire:

POST /create HTTP/1.1
Host: www.example.com
Content-Type: application/x-www-form-urlencoded;charset=UTF-8
Content-Length: 25

param1=hello&param2=world

The content is URL encoded in this case.

If you do not know the names of the FormParam's you can do the following:

@POST @Consumes("application/x-www-form-urlencoded")
@Path("/create")
public void create(final MultivaluedMap<String, String> formParams) {
    ...
}

HTTP Headers

You can using the @HeaderParam annotation if you want to pass parameters via HTTP headers:

@POST
@Path("/create")
public void create(@HeaderParam("param1") String param1,
                   @HeaderParam("param2") String param2) {
    ...
}

Here's what the HTTP message would look like. Note that this POST does not have a body.

POST /create HTTP/1.1
Content-Length: 0
Host: www.example.com
param1: hello
param2: world

I wouldn't use this method for generalized parameter passing. It is really handy if you need to access the value of a particular HTTP header though.

HTTP Query Parameters

This method is primarily used with HTTP GETs but it is equally applicable to POSTs. It uses the @QueryParam annotation.

@POST
@Path("/create")
public void create(@QueryParam("param1") String param1,
                   @QueryParam("param2") String param2) {
    ...
}

Like the previous technique, passing parameters via the query string does not require a message body. Here's the HTTP message:

POST /create?param1=hello&param2=world HTTP/1.1
Content-Length: 0
Host: www.example.com

You do have to be particularly careful to properly encode query parameters on the client side. Using query parameters can be problematic due to URL length restrictions enforced by some proxies as well as problems associated with encoding them.

HTTP Path Parameters

Path parameters are similar to query parameters except that they are embedded in the HTTP resource path. This method seems to be in favor today. There are impacts with respect to HTTP caching since the path is what really defines the HTTP resource. The code looks a little different than the others since the @Path annotation is modified and it uses @PathParam:

@POST
@Path("/create/{param1}/{param2}")
public void create(@PathParam("param1") String param1,
                   @PathParam("param2") String param2) {
    ...
}

The message is similar to the query parameter version except that the names of the parameters are not included anywhere in the message.

POST /create/hello/world HTTP/1.1
Content-Length: 0
Host: www.example.com

This method shares the same encoding woes that the query parameter version. Path segments are encoded differently so you do have to be careful there as well.

As you can see, there are pros and cons to each method. The choice is usually decided by your clients. If you are serving FORM-based HTML pages, then use @FormParam. If your clients are JavaScript+HTML5-based, then you will probably want to use JAXB-based serialization and JSON objects. The MessageBodyReader/Writer implementations should take care of the necessary escaping for you so that is one fewer thing that can go wrong. If your client is Java based but does not have a good XML processor (e.g., Android), then I would probably use FORM encoding since a content body is easier to generate and encode properly than URLs are. Hopefully this mini-wiki entry sheds some light on the various methods that JAX-RS supports.

Note: in the interest of full disclosure, I haven't actually used this feature of Jersey yet. We were tinkering with it since we have a number of JAXB+JAX-RS applications deployed and are moving into the mobile client space. JSON is a much better fit that XML on HTML5 or jQuery-based solutions.

There is some progress for Visual studio 2013 developers :-D woot woot! See blog post Visual Studio Installer Projects Extension.

Link and information were retrieved from Brian Harry's blog post Creating installers with Visual Studio.

I think the reason that this is happening could be because TextBox1 is scoping to the VBA module and its associated sheet, while Range is scoping to the "Active Sheet".

EDIT

It looks like you may be able to use the GetObject function to pull the textbox from the workbook.

You'll have to loop over the set of columns and check each one. You should be able to get a list of all columns with a DESCRIBE table command.

Pseudo-code:

foreach $column ($cols) {
   query("SELECT count(*) FROM table WHERE $column IS NOT NULL")
   if($result is zero)  {
      # $column contains only null values"
      push @onlyNullColumns, $column;
   } else {
      # $column contains non-null values
   }
}
return @onlyNullColumns;

I know this seems a little counterintuitive but SQL does not provide a native method of selecting columns, only rows.

Five years later, when I Google "how to create a kernel density plot using python", this thread still shows up at the top!

Today, a much easier way to do this is to use seaborn, a package that provides many convenient plotting functions and good style management.

import numpy as np
import seaborn as sns
data = [1.5]*7 + [2.5]*2 + [3.5]*8 + [4.5]*3 + [5.5]*1 + [6.5]*8
sns.set_style('whitegrid')
sns.kdeplot(np.array(data), bw=0.5)

The built-in string constructor will automatically call obj.__str__:

''.join(map(str,list))

Just wanted to quickly add (because I didn't see it in any of the answers) that, for a named list, you can also do l["name"] <- NULL. For example:

l <- list(a = 1, b = 2, cc = 3)
l['b'] <- NULL

    if (fieldName.endsWith(",")) {
        fieldName = fieldName.substring(0, fieldName.length()-1) + " ";
    }

To solve, I needed to revert the file with problem, and update my working copy, and later I modified the file again and after these steps the error didn't happened anymore.

you can try this out,if you want to remove origin and then add it:

git remote remove origin

then:

git remote add origin http://your_url_here

Try simple typecasting

char c = (char) i;

Just one line of code in xml

        android:textStyle="italic"

Another relevant environment variable is:

%ProgramW6432%

So, on a 64-bit machine running in 32-bit (WOW64) mode:

• echo %programfiles% ==> C:\Program Files (x86)
• echo %programfiles(x86)% ==> C:\Program Files (x86)
• echo %ProgramW6432% ==> C:\Program Files

From Wikipedia:

The %ProgramFiles% variable points to the Program Files directory, which stores all the installed programs of Windows and others. The default on English-language systems is "C:\Program Files". In 64-bit editions of Windows (XP, 2003, Vista), there are also %ProgramFiles(x86)%, which defaults to "C:\Program Files (x86)", and %ProgramW6432%, which defaults to "C:\Program Files". The %ProgramFiles% itself depends on whether the process requesting the environment variable is itself 32-bit or 64-bit (this is caused by Windows-on-Windows 64-bit redirection).

Searched several houres before I found there were some linebreaks in the included files.

Use 'a', 'a' means append. Anything written to a file opened with 'a' attribute is written at the end of the file.

with open('file.txt', 'a') as file:
    file.write('input')

const ClassToggleFC= () =>{
  
  const [isClass, setClass] = useState(false);

  const toggle =() => {
       setClass( prevState => !prevState)
  }
  
  return(
      <>
        <h1 className={ isClass ? "heading" : ""}> Hiii There </h1>
       <button onClick={toggle}>Toggle</button>
      </>
   )

}

I simply created a Function Component. Inside I take a state and set initial value is false..

I have a button for toggling state..

Whenever we change state rerender component and if state value (isClass) is false h1's className should be "" and if state value (isClass) is true h1's className is "heading"

JavaScript closures can be used to implement throttle and debounce functionality in your application.

Throttling

Throttling puts a limit on as a maximum number of times a function can be called over time. As in "execute this function at most once every 100 milliseconds."

Code:

const throttle = (func, limit) => {
  let isThrottling
  return function() {
    const args = arguments
    const context = this
    if (!isThrottling) {
      func.apply(context, args)
      isThrottling = true
      setTimeout(() => isThrottling = false, limit)
    }
  }
}

Debouncing

Debouncing puts a limit on a function not be called again until a certain amount of time has passed without it being called. As in "execute this function only if 100 milliseconds have passed without it being called."

Code:

const debounce = (func, delay) => {
  let debouncing
  return function() {
    const context = this
    const args = arguments
    clearTimeout(debouncing)
    debouncing = setTimeout(() => func.apply(context, args), delay)
  }
}

As you can see closures helped in implementing two beautiful features which every web application should have to provide smooth UI experience functionality.

I had the same error, as Bombe said I had no local branch named master in my config, although git branch did list a branch named master...

To fix it just add this to your .git/config

[branch "master"]
    remote = origin
    merge = refs/heads/master

Kinda hacky but does the job

This can be achieved in various methods in Swift 3.0 Worked on Latest version MAY- 2019

Directly assign the Height & Width values for a view:

userView.frame.size.height = 0

userView.frame.size.width = 10

Assign the CGRect for the Frame

userView.frame =  CGRect(x:0, y: 0, width:0, height:0)

Method Details:

CGRect(x: point of X, y: point of Y, width: Width of View, height: Height of View)

Using an Extension method for CGRECT

Add following extension code in any swift file,

extension CGRect {

    init(_ x:CGFloat, _ y:CGFloat, _ w:CGFloat, _ h:CGFloat) {

        self.init(x:x, y:y, width:w, height:h)
    }
}

Use the following code anywhere in your application for the view to set the size parameters

userView.frame =  CGRect(1, 1, 20, 45)

Running STS on Java Spring Boot projects, here's what works for me :

I use a generic query I call "dump" (why? I don't know) that looks like this:

SET ECHO OFF
SET FEEDBACK OFF
SET VERIFY OFF
SET HEADING OFF
SET TERMOUT OFF
SET TRIMOUT ON
SET TRIMSPOOL ON
SET COLSEP |

I then call SQL*Plus passing the actual SQL script I want to run as an argument:

sqlplus -S user/password@database @dump.sql my_real_query.sql

The result is written to a file

The value you want to change is response_www_authenticate.

Ids are supposed to be unique document wide, so you shouldn't have to select based on both. You can assign an element multiple classes though with class="class1 class2"

Coming from the embedded world, where even uclibc is not always available, and code like

uint64_t myval = 0xdeadfacedeadbeef; printf("%llx", myval);

is printing you crap or not working at all -- i always use a tiny helper, that allows me to dump properly uint64_t hex:

#include <stdlib.h>
#include <stdio.h>
#include <stdint.h>

char* ullx(uint64_t val)
{
    static char buf[34] = { [0 ... 33] = 0 };
    char* out = &buf[33];
    uint64_t hval = val;
    unsigned int hbase = 16;

    do {
        *out = "0123456789abcdef"[hval % hbase];
        --out;
        hval /= hbase;
    } while(hval);

    *out-- = 'x', *out = '0';

    return out;
}

Here's a quick way I've found to make a two dimensional array.

function createArray(x, y) {
    return Array.apply(null, Array(x)).map(e => Array(y));
}

You can easily turn this function into an ES5 function as well.

function createArray(x, y) {
    return Array.apply(null, Array(x)).map(function(e) {
        return Array(y);
    });
}

Why this works: the new Array(n) constructor creates an object with a prototype of Array.prototype and then assigns the object's length, resulting in an unpopulated array. Due to its lack of actual members we can't run the Array.prototype.map function on it.

However, when you provide more than one argument to the constructor, such as when you do Array(1, 2, 3, 4), the constructor will use the arguments object to instantiate and populate an Array object correctly.

For this reason, we can use Array.apply(null, Array(x)), because the apply function will spread the arguments into the constructor. For clarification, doing Array.apply(null, Array(3)) is equivalent to doing Array(null, null, null).

Now that we've created an actual populated array, all we need to do is call map and create the second layer (y).

those icons are a way of Egit to show you status of the current file/folder in git. You might want to check this out:

• dirty (folder) - At least one file below the folder is dirty; that means that it has changes in the working tree that are neither in the index nor in the repository.
• tracked - The resource is known to the Git repository. untracked - The resource is not known to the Git repository.
• ignored - The resource is ignored by the Git team provider. Here only the preference settings under Team -> Ignored Resources and the "derived" flag are relevant. The .gitignore file is not taken into account.
• dirty - The resource has changes in the working tree that are neither in the index nor in the repository.
• staged - The resource has changes which are added to the index. Not that adding to the index is possible at the moment only on the commit dialog on the context menu of a resource.
• partially-staged - The resource has changes which are added to the index and additionally changes in the working tree that are neither in the index nor in the repository.
• added - The resource is not yet tracked by but added to the Git repository.
• removed - The resource is staged for removal from the Git repository.
• conflict - A merge conflict exists for the file.
• assume-valid - The resource has the "assume unchanged" flag. This means that Git stops checking the working tree files for possible modifications, so you need to manually unset the bit to tell Git when you change the working tree file. This setting can be switched on with the menu action Team->Assume unchanged (or on the command line with git update-index--assume-unchanged).

fmod is the standard C function for handling floating-point modulus; I imagine your source was saying that Java handles floating-point modulus the same as C's fmod function. In Java you can use the % operator on doubles the same as on integers:

int x = 5 % 3; // x = 2
double y = .5 % .3; // y = .2
