    yearRange: "-100:+0",
    dateFormat: 'dd/mm/yy'

});
</script>

@Massagran: It works well in my programs. Furthermore, we need to add a counter to indicate the loop times. This counter plays as the argument of the method update. For example: read all lines of a test file and treat them on something. Suppose that the function dosth() do not concern in the variable i.

lines = open(sys.argv[1]).readlines()
i = 0
widgets=[Percentage(), Bar()]
pbar = ProgressBar(widgets=widgets,maxval=len(lines)).start()
pbar.start()
for line in lines:<pre>
    dosth();
    i += 1
    pbar.update(i)</pre>
pbar.finish()

The variable i controls the status of pbar via the method update

Several years too late:

Just for completeness I want to give yet another answer:

First, go to Excel-Options -> Formulas and enable R1C1 references. Then use

  =CELL("width", RC)

RC always refers the current Row, current Column, i.e. "this cell".

Rick Teachey's solution is basically a tweak to make the same possible in A1 reference style (see also GSerg's comment to Joey's answer and note his comment to Patrick McDonald's answer).

Cheers

When you have the expression:

a % b = c

It really means there exists an integer n that makes c as small as possible, but non-negative.

a - n*b = c

By hand, you can just subtract 2 (or add 2 if your number is negative) over and over until the end result is the smallest positive number possible:

  3.14 % 2
= 3.14 - 1 * 2
= 1.14

Also, 3.14 % 2 * pi is interpreted as (3.14 % 2) * pi. I'm not sure if you meant to write 3.14 % (2 * pi) (in either case, the algorithm is the same. Just subtract/add until the number is as small as possible).

You need to name the entity that holds the association to User. For example,

... INNER JOIN ug.user u ...

That's the "path" the error message is complaining about -- path from UserGroup to User entity.

Hibernate relies on declarative JOINs, for which the join condition is declared in the mapping metadata. This is why it is impossible to construct the native SQL query without having the path.

Here are some I can think about :

• With bindParam, you can only pass variables ; not values
• with bindValue, you can pass both (values, obviously, and variables)
• bindParam works only with variables because it allows parameters to be given as input/output, by "reference" (and a value is not a valid "reference" in PHP) : it is useful with drivers that (quoting the manual) :

support the invocation of stored procedures that return data as output parameters, and some also as input/output parameters that both send in data and are updated to receive it.

With some DB engines, stored procedures can have parameters that can be used for both input (giving a value from PHP to the procedure) and ouput (returning a value from the stored proc to PHP) ; to bind those parameters, you've got to use bindParam, and not bindValue.

Spring uses dependency injection to populate the specific value when it finds the @Value annotation. However, instead of handing the value to the instance variable, it's handed to the implicit setter instead. This setter then handles the population of our NAME_STATIC value.

    @RestController 
//or if you want to declare some specific use of the properties file then use
//@Configuration
//@PropertySource({"classpath:application-${youeEnvironment}.properties"})
public class PropertyController {

    @Value("${name}")//not necessary
    private String name;//not necessary

    private static String NAME_STATIC;

    @Value("${name}")
    public void setNameStatic(String name){
        PropertyController.NAME_STATIC = name;
    }
}

import pathlib

print(pathlib.Path('yourPath.example').suffix) # '.example'

I'm surprised no one has mentioned pathlib yet, pathlib IS awesome!

If you need all the suffixes (eg if you have a .tar.gz), .suffixes will return a list of them!

Simple fundamentals, Elastic community has exposed indexing, searching, deleting operation as rest web service. You can interact elastic using curl or sense(chrome plugin) or any rest client like postman.

If you are just testing few commands, I would recommend can use of sense chrome plugin which has simple UI and pretty mature plugin now.

I have seen comments in INI files, so yes. Please refer to this Wikipedia article. I could not find an official specification, but that is the correct syntax for comments, as many game INI files had this as I remember.

Edit

The API returns the Value and the Comment (forgot to mention this in my reply), just construct and example INI file and call the API on this (with comments) and you can see how this is returned.

You can use this

char name[20];
scanf("%20[^\n]", name);

Or this

void getText(char *message, char *variable, int size){
    printf("\n %s: ", message);
    fgets(variable, sizeof(char) * size, stdin);
    sscanf(variable, "%[^\n]", variable);
}

char name[20];
getText("Your name", name, 20);

If you don't want to lose the columns you shift past the end of your dataframe, simply append the required number first:

    offset = 5
    DF = DF.append([np.nan for x in range(offset)])
    DF = DF.shift(periods=offset)
    DF = DF.reset_index() #Only works if sequential index

Assuming ASCII strings:

string1 = 'Hello'
string2 = 'hello'

if string1.lower() == string2.lower():
    print("The strings are the same (case insensitive)")
else:
    print("The strings are NOT the same (case insensitive)")

Here's how I'd do it:

def distance(a,b):
    return sqrt((a.x - b.x)**2 + (a.y - b.y)**2)

def is_between(a,c,b):
    return distance(a,c) + distance(c,b) == distance(a,b)

If you're going to be adding to this dictionary frequently you'd want to take a class based approach, something similar to @Latty's answer in this SO question 2d-dictionary-with-many-keys-that-will-return-the-same-value.

However, if you have a static dictionary, and you need only access values by multiple keys then you could just go the very simple route of using two dictionaries. One to store the alias key association and one to store your actual data:

alias = {
    'a': 'id1',
    'b': 'id1',
    'c': 'id2',
    'd': 'id2'
}

dictionary = {
    'id1': 1,
    'id2': 2
}

dictionary[alias['a']]

If you need to add to the dictionary you could write a function like this for using both dictionaries:

def add(key, id, value=None)
    if id in dictionary:
        if key in alias:
            # Do nothing
            pass
        else:
            alias[key] = id
    else:
        dictionary[id] = value
        alias[key] = id

add('e', 'id2')
add('f', 'id3', 3)

While this works, I think ultimately if you want to do something like this writing your own data structure is probably the way to go, though it could use a similar structure.

So do you want them to get the IE password-challenge box, or should they be directed to your login page and enter their information there? If it's the second option, then you should at least enable Anonymous access to your login page, since the site won't know who they are yet.

If you want the first option, then the login page they're getting forwarded to will need to read the currently logged-in user and act based on that, since they would have had to correctly authenticate to get this far.

A very simple way of doing this is to use reset_index() method.For a data frame df use the code below:

df.reset_index(inplace=True)

This way, the index will become a column, and by using inplace as True,this become permanent change.

If you are using PHP 5 you can try this:

function a() {
    $trace = debug_backtrace();
    echo $trace[0]["function"];
}

If you can do this in java, try:

RuntimeMXBean

ManagementFactory

Example:

RuntimeMXBean runtimeMXBean = ManagementFactory.getRuntimeMXBean();
List<String> jvmArgs = runtimeMXBean.getInputArguments();
for (String arg : jvmArgs) {
    System.out.println(arg);
}

'lines' term from your snippet consists of set of strings.

 lines = f.readlines()
 match = re.findall('[A-Z]+', lines)

You cannot send entire lines into the re.findall('pattern',<string>)

You can try to send line by line

 for i in lines:
  match = re.findall('[A-Z]+', i)
  print match

or to convert the entire lines collection into single line (each line seperated by space)

 NEW_LIST=' '.join(lines)
 match=re.findall('[A-Z]+' ,NEW_LIST)
 print match

This might help you

Here's a somewhat cleaner way of implementing this. This makes the following changes:

1. The code is DRYed up a bit to remove redundant and repeated code and strings.
2. The code is made more generic/reusable.
3. We make the cache into an object so it has a self-contained interface and there are fewer globals.
4. We compare .src attributes instead of DOM elements to make it work properly.

Code:

function imageCache(base, firstNum, lastNum) {
    this.cache = [];
    var img;
    for (var i = firstNum; i <= lastnum; i++) {
        img = new Image();
        img.src = base + i + ".jpg";
        this.cache.push(img);
    }
}

imageCache.prototype.nextImage(id) {
    var element = document.getElementById(id);
    var targetSrc = element.src;
    var cache = this.cache;
    for (var i = 0; i < cache.length; i++) {
        if (cache[i].src) === targetSrc) {
            i++;
            if (i >= cache.length) {
                i = 0;
            }
            element.src = cache[i].src;
            return;
        }
    }
}

// sample usage

var myCache = new imageCache('images/img/Splash_image', 1, 6);
myCache.nextImage("foo");

Some advantages of this more object oriented and DRYed approach:

1. You can add more images by just creating the images in the numeric sequences and changing one numeric value in the constructor rather than copying lots more lines of array declarations.
2. You can use this more than one place in your app by just creating more than one imageCache object.
3. You can change the base URL by changing one string rather than N strings.
4. The code size is smaller (because of the removal of repeated code).
5. The cache object could easily be extended to offer more capabilities such as first, last, skip, etc...
6. You could add centralize error handling in one place so if one image doesn't exist and doesn't load successfully, it's automatically removed from the cache.
7. You can reuse this in other web pages you develop by only change the arguments to the constructor and not actually changing the implementation code.

P.S. If you don't know what DRY stands for, it's "Don't Repeat Yourself" and basically means that you should never have many copies of similar looking code. Anytime you have that, it should be reduced somehow to a loop or function or something that removes the need for lots of similarly looking copies of code. The end result will be smaller, usually easier to maintain and often more reusable.

Yes changing the error_to debug level as Emmanuel Joubaud suggested worked out (edit /etc/nginx/sites-enabled/default ):

        error_log /var/log/nginx/error.log debug;

Then after restaring nginx I got in the error log with my Python application using uwsgi:

Then I took a look to my uwsgi log and found out that:

        Invalid HTTP_HOST header: 'www.mysite.local'. You may need to add u'www.mysite.local' to ALLOWED_HOSTS.
        [pid: 10903|app: 0|req: 2/4] 192.168.221.2 () {38 vars in 450 bytes} [Wed Feb  8 22:32:24 2017] GET / => generated 54098 bytes in 55 msecs (HTTP/1.1 400) 4 headers in 135 bytes (1 switches on core 0)

And adding www.mysite.local to the settings.py ALLOWED_HOSTS fixed the issue :)

        ALLOWED_HOSTS = ['www.mysite.local']

If the characters you want to remove are always the same characters, then consider chomp:

'abc123'.chomp('123')    # => "abc"

The advantages of chomp are: no counting, and the code more clearly communicates what it is doing.

With no arguments, chomp removes the DOS or Unix line ending, if either is present:

"abc\n".chomp      # => "abc"
"abc\r\n".chomp    # => "abc"

From the comments, there was a question of the speed of using #chomp versus using a range. Here is a benchmark comparing the two:

require 'benchmark'

S = 'asdfghjkl'
SL = S.length
T = 10_000
A = 1_000.times.map { |n| "#{n}#{S}" }

GC.disable

Benchmark.bmbm do |x|
  x.report('chomp') { T.times { A.each { |s| s.chomp(S) } } }
  x.report('range') { T.times { A.each { |s| s[0...-SL] } } }
end

Benchmark Results (using CRuby 2.13p242):

Rehearsal -----------------------------------------
chomp   1.540000   0.040000   1.580000 (  1.587908)
range   1.810000   0.200000   2.010000 (  2.011846)
-------------------------------- total: 3.590000sec

            user     system      total        real
chomp   1.550000   0.070000   1.620000 (  1.610362)
range   1.970000   0.170000   2.140000 (  2.146682)

So chomp is faster than using a range, by ~22%.

If you're using dom4j, you can just do:

Document document = DocumentHelper.parseText(text);

(dom4j now found here: https://github.com/dom4j/dom4j)

That question solved a quite similar question for me and I thought I should share :

In raw python you can use sum() to count True values in a list :

>>> sum([True,True,True,False,False])
3

But this won't work :

>>> sum([[False, False, True], [True, False, True]])
TypeError...

I found a new way that works for me perfetly

var win = window.open("about:blank", "_self");
win.close();

this:

(<.+?> | &nbsp;)

will match any tag or  

string regex = @"(<.+?>|&nbsp;)";
var x = Regex.Replace(originalString, regex, "").Trim();

then x = hello

I have a more automated solution for this.

HTML:

<form role="form" enctype="multipart/form-data" action="{{ $url }}" method="{{ $method }}">
    {{ csrf_field() }}

    <!-- You can add extra form fields here -->

    <input hidden id="file" name="file"/>

    <!-- You can add extra form fields here -->

    <div class="dropzone dropzone-file-area" id="fileUpload">
        <div class="dz-default dz-message">
            <h3 class="sbold">Drop files here to upload</h3>
            <span>You can also click to open file browser</span>
        </div>
    </div>

    <!-- You can add extra form fields here -->

    <button type="submit">Submit</button>
</form>

JavaScript:

Dropzone.options.fileUpload = {
    url: 'blackHole.php',
    addRemoveLinks: true,
    accept: function(file) {
        let fileReader = new FileReader();

        fileReader.readAsDataURL(file);
        fileReader.onloadend = function() {

            let content = fileReader.result;
            $('#file').val(content);
            file.previewElement.classList.add("dz-success");
        }
        file.previewElement.classList.add("dz-complete");
    }
}

Laravel:

// Get file content
$file = base64_decode(request('file'));

No need to disable DropZone Discovery and the normal form submit will be able to send the file with any other form fields through standard form serialization.

This mechanism stores the file contents as base64 string in the hidden input field when it gets processed. You can decode it back to binary string in PHP through the standard base64_decode() method.

I don't know whether this method will get compromised with large files but it works with ~40MB files.

You can edit your readme.md with instructions to install your laravel app in other environment like this:

## Create folders

```
#!terminal

cp .env.example .env && mkdir bootstrap/cache storage storage/framework && cd storage/framework && mkdir sessions views cache

```

## Folder permissions

```
#!terminal

sudo chown :www-data app storage bootstrap -R
sudo chmod 775 app storage bootstrap -R

```

## Install dependencies

```
#!terminal

composer install

```

Here the passage from the MSDN:

When you specify a PRIMARY KEY constraint for a table, the Database Engine enforces data uniqueness by creating a unique index for the primary key columns. This index also permits fast access to data when the primary key is used in queries. Therefore, the primary keys that are chosen must follow the rules for creating unique indexes.

Flexible Box Layout Module - 8.1. Aligning with auto margins

Auto margins on flex items have an effect very similar to auto margins in block flow:

• During calculations of flex bases and flexible lengths, auto margins are treated as 0.

• Prior to alignment via justify-content and align-self, any positive free space is distributed to auto margins in that dimension.

Therefore you could use margin-top: auto to distribute the space between the other elements and the last element.

This will position the last element at the bottom.

p:last-of-type {
  margin-top: auto;
}

.container {
  display: flex;
  flex-direction: column;
  border: 1px solid #000;
  min-height: 200px;
  width: 100px;
}
p {
  height: 30px;
  background-color: blue;
  margin: 5px;
}
p:last-of-type {
  margin-top: auto;
}

<div class="container">
  <p></p>
  <p></p>
  <p></p>
</div>

Likewise, you can also use margin-left: auto or margin-right: auto for the same alignment horizontally.

p:last-of-type {
  margin-left: auto;
}

.container {
  display: flex;
  width: 100%;
  border: 1px solid #000;
}
p {
  height: 50px;
  width: 50px;
  background-color: blue;
  margin: 5px;
}
p:last-of-type {
  margin-left: auto;
}

<div class="container">
  <p></p>
  <p></p>
  <p></p>
  <p></p>
</div>

I've had great success with this:

#include <iostream>
#include <windows.h>

int main() {
    ShellExecute(NULL, "open", "path\\to\\file.exe", NULL, NULL, SW_SHOWDEFAULT);
}

If you're interested, the full documentation is here:

Had this issue occur when everything seemed to be setup correctly, build setting were pointing to correct provisioning profile, code signing was properly setup, etc.

Issue occurred because I had just created a new scheme and hadn't regenerated my CocoaPods for the new configurations. As you can see from the image, the new ad-hoc configuration is pointing to the Pods.production configuration, instead of a Pods.ad-hoc configuration (and test respectively)

To fix:

• Set the offending configuration to None -- cocoapods wouldn't generate the configs unless I did this
• Close XCode
• Run pod install
• Re-open XCode and set the new scheme's configurations to the newly generated configurations.

That's it!

Element is not supported in IE8 out of the box you have to do some work to make IE8 accept custom tags.

One advantage of using an attribute over an element is that you can apply multiple directives to the same DOM node. This is particularly handy for things like form controls where you can highlight, disable, or add labels etc. with additional attributes without having to wrap the element in a bunch of tags.

This only works for powers of two (and frequently only positive ones) because they have the unique property of having only one bit set to '1' in their binary representation. Because no other class of numbers shares this property, you can't create bitwise-and expressions for most modulus expressions.

Assembly.GetExecutingAssembly().Location

This problem is due to:

• an old version of pip (6.1.1) being installed for Python 2.7
• multiple copies of Python 2.7 installed on the Trusty Beta image
• a different location for Python 2.7 being used for sudo

It's all a bit complicated and better explained here https://github.com/travis-ci/travis-ci/issues/4989.

My solution was to install with user travis instead of sudo:

- pip2.7 install --upgrade --user travis pip setuptools wheel virtualenv

We can access super class elements by using super keyword

Consider we have two classes, Parent class and Child class, with different implementations of method foo. Now in child class if we want to call the method foo of parent class, we can do so by super.foo(); we can also access parent elements by super keyword.

    class parent {
    String str="I am parent";
    //method of parent Class
    public void foo() {
        System.out.println("Hello World " + str);
    }
}

class child extends parent {
    String str="I am child";
    // different foo implementation in child Class
    public void foo() {
        System.out.println("Hello World "+str);
    }

    // calling the foo method of parent class
    public void parentClassFoo(){
        super.foo();
    }

    // changing the value of str in parent class and calling the foo method of parent class
    public void parentClassFooStr(){
        super.str="parent string changed";
        super.foo();
    }
}


public class Main{
        public static void main(String args[]) {
            child obj = new child();
            obj.foo();
            obj.parentClassFoo();
            obj.parentClassFooStr();
        }
    }

In case you want to search for all the issues updated after 9am previous day until today at 9AM, please try: updated >= startOfDay(-15h) and updated <= startOfDay(9h). (explanation: 9AM - 24h/day = -15h)

You can also use updated >= startOfDay(-900m) . where 900m = 15h*60m

Open Task Manager and Kill both of these processes. They will autostart back up. Then try debugging your project again.

It looks like you are not providing a value for the primary key field DB_ID. If that is a primary key, you must provide a unique value for that column. The only way not to provide it would be to create a database trigger that, on insert, would provide a value, most likely derived from a sequence.

If this is a restoration from another database and there is a sequence on this new instance, it might be trying to reuse a value. If the old data had unique keys from 1 - 1000 and your current sequence is at 500, it would be generating values that already exist. If a sequence does exist for this table and it is trying to use it, you would need to reconcile the values in your table with the current value of the sequence.

You can use SEQUENCE_NAME.CURRVAL to see the current value of the sequence (if it exists of course)

position: fixed;

Will make this happen.

It handles like position:absolute; with the exception that it will scroll with the window as the user scrolls down the content.

The command scp can be used like a traditional UNIX cp. SO if you do :

scp -r myDirectory/ mylogin@host:TargetDirectory

will work

First you may check query when the target column is type bool (PS: about how to use it please check link )

df.query('BoolCol')
Out[123]: 
    BoolCol
10     True
40     True
50     True

After we filter the original df by the Boolean column we can pick the index .

df=df.query('BoolCol')
df.index
Out[125]: Int64Index([10, 40, 50], dtype='int64')

Also pandas have nonzero, we just select the position of True row and using it slice the DataFrame or index

df.index[df.BoolCol.nonzero()[0]]
Out[128]: Int64Index([10, 40, 50], dtype='int64')

You can use the Axes.set_yscale method. That allows you to change the scale after the Axes object is created. That would also allow you to build a control to let the user pick the scale if you needed to.

The relevant line to add is:

ax.set_yscale('log')

You can use 'linear' to switch back to a linear scale. Here's what your code would look like:

import pylab
import matplotlib.pyplot as plt
a = [pow(10, i) for i in range(10)]
fig = plt.figure()
ax = fig.add_subplot(2, 1, 1)

line, = ax.plot(a, color='blue', lw=2)

ax.set_yscale('log')

pylab.show()

I found this on the Bootstrap website, but it really isn't a Bootstrap class, it's just HTML.

<strong>rendered as bold text</strong>

Real problem is when you need draw some tile/sprites intersecting/spanning two or more other tiles.

After 2 (hard) months of personal analisys of problem I finally found and implemented a "correct render drawing" for my new cocos2d-js game. Solution consists in mapping, for each tile (susceptible), which sprites are "front, back, top and behind". Once doing that you can draw them following a "recursive logic".

"use strict";

Basically it enables the strict mode.

Strict Mode is a feature that allows you to place a program, or a function, in a "strict" operating context. In strict operating context, the method form binds this to the objects as before. The function form binds this to undefined, not the global set objects.

As per your comments you are telling some differences will be there. But it's your assumption. The Node.js code is nothing but your JavaScript code. All Node.js code are interpreted by the V8 JavaScript engine. The V8 JavaScript Engine is an open source JavaScript engine developed by Google for Chrome web browser.

So, there will be no major difference how "use strict"; is interpreted by the Chrome browser and Node.js.

Please read what is strict mode in JavaScript.

For more information:

1. Strict mode
2. ECMAScript 5 Strict mode support in browsers
3. Strict mode is coming to town
4. Compatibility table for strict mode
5. Stack Overflow questions: what does 'use strict' do in JavaScript & what is the reasoning behind it

ECMAScript 6 Code & strict mode. Following is brief from the specification:

10.2.1 Strict Mode Code

An ECMAScript Script syntactic unit may be processed using either unrestricted or strict mode syntax and semantics. Code is interpreted as strict mode code in the following situations:

• Global code is strict mode code if it begins with a Directive Prologue that contains a Use Strict Directive (see 14.1.1).
• Module code is always strict mode code.
• All parts of a ClassDeclaration or a ClassExpression are strict mode code.
• Eval code is strict mode code if it begins with a Directive Prologue that contains a Use Strict Directive or if the call to eval is a direct eval (see 12.3.4.1) that is contained in strict mode code.
• Function code is strict mode code if the associated FunctionDeclaration, FunctionExpression, GeneratorDeclaration, GeneratorExpression, MethodDefinition, or ArrowFunction is contained in strict mode code or if the code that produces the value of the function’s [[ECMAScriptCode]] internal slot begins with a Directive Prologue that contains a Use Strict Directive.
• Function code that is supplied as the arguments to the built-in Function and Generator constructors is strict mode code if the last argument is a String that when processed is a FunctionBody that begins with a Directive Prologue that contains a Use Strict Directive.

Additionally if you are lost on what features are supported by your current version of Node.js, this node.green can help you (leverages from the same data as kangax).

I'll assume you mean the URI:

class BankController < ActionController::Base
  before_filter :pre_process 

  def index
    # do something
  end

  private
    def pre_process
      logger.debug("The URL" + request.url)
    end
end

As per your comment below, if you need the name of the controller, you can simply do this:

  private
    def pre_process
      self.controller_name        #  Will return "order"
      self.controller_class_name  # Will return "OrderController"
    end

View and check the reference paths in your csproj.

I had removed references to System.Web.Mvc (and others) and readded them to a custom path. C:\Project\OurWebReferences

However, after doing this, the reference path in the still csproj did not change. WAS

Update: req.param() is now deprecated, so going forward do not use this answer.

Your answer is the preferred way to do it, however I thought I'd point out that you can also access url, post, and route parameters all with req.param(parameterName, defaultValue).

In your case:

var color = req.param('color');

From the express guide:

lookup is performed in the following order:

• req.params
• req.body
• req.query

Note the guide does state the following:

Direct access to req.body, req.params, and req.query should be favoured for clarity - unless you truly accept input from each object.

However in practice I've actually found req.param() to be clear enough and makes certain types of refactoring easier.

There is an important point of arrays that is often not taught or missed in java classes. When arrays are passed to a function, then another pointer is created to the same array ( the same pointer is never passed ). You can manipulate the array using both the pointers, but once you assign the second pointer to a new array in the called method and return back by void to calling function, then the original pointer still remains unchanged.

You can directly run the code here : https://www.compilejava.net/

import java.util.Arrays;

public class HelloWorld
{
    public static void main(String[] args)
    {
        int Main_Array[] = {20,19,18,4,16,15,14,4,12,11,9};
        Demo1.Demo1(Main_Array);
        // THE POINTER Main_Array IS NOT PASSED TO Demo1
        // A DIFFERENT POINTER TO THE SAME LOCATION OF Main_Array IS PASSED TO Demo1

        System.out.println("Main_Array = "+Arrays.toString(Main_Array));
        // outputs : Main_Array = [20, 19, 18, 4, 16, 15, 14, 4, 12, 11, 9]
        // Since Main_Array points to the original location,
        // I cannot access the results of Demo1 , Demo2 when they are void.
        // I can use array clone method in Demo1 to get the required result,
        // but it would be faster if Demo1 returned the result to main
    }
}

public class Demo1
{
    public static void Demo1(int A[])
    {
        int B[] = new int[A.length];
        System.out.println("B = "+Arrays.toString(B)); // output : B = [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0]
        Demo2.Demo2(A,B);
        System.out.println("B = "+Arrays.toString(B)); // output : B = [9999, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0]
        System.out.println("A = "+Arrays.toString(A)); // output : A = [20, 19, 18, 4, 16, 15, 14, 4, 12, 11, 9]

        A = B;
        // A was pointing to location of Main_Array, now it points to location of B
        // Main_Array pointer still keeps pointing to the original location in void main

        System.out.println("A = "+Arrays.toString(A)); // output : A = [9999, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0]
        // Hence to access this result from main, I have to return it to main
    }
}
public class Demo2
{
    public static void Demo2(int AAA[],int BBB[])
    {
        BBB[0] = 9999;
        // BBB points to the same location as B in Demo1, so whatever I do
        // with BBB, I am manipulating the location. Since B points to the
        // same location, I can access the results from B
    }
}

Here is a query that returns only the rows where no correspondance has been found in both columns user_one and user_two of table2:

SELECT T1.*
FROM table1 T1
LEFT OUTER JOIN table2 T2A ON T2A.user_one = T1.id
LEFT OUTER JOIN table2 T2B ON T2B.user_two = T1.id
WHERE T2A.user_one IS NULL
    AND T2B.user_two IS NULL

There is one jointure for each column (user_one and user_two) and the query only returns rows that have no matching jointure.

Hope this will help you.

You can use negative integers with the slicing operator for that. Here's an example using the python CLI interpreter:

>>> a = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12]
>>> a
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12]
>>> a[-9:]
[4, 5, 6, 7, 8, 9, 10, 11, 12]

the important line is a[-9:]

I need to sum the span elements so I edited Akhil Sekharan's answer below.

var arr = document.querySelectorAll('span[id^="score"]');
var total=0;
    for(var i=0;i<arr.length;i++){
        if(parseInt(arr[i].innerHTML))
            total+= parseInt(arr[i].innerHTML);
    }
console.log(total)

You can change the elements with other elements link will guide you with editing.

I have a slightly different way of doing this than the accepted answer. This way you can avoid using GROUP_CONCAT which has a limit of 1024 characters and will not work if you have a lot of fields.

SET @sql = '';
SELECT
    @sql := CONCAT(@sql,if(@sql='','',', '),temp.output)
FROM
(
    SELECT
      DISTINCT
        CONCAT(
         'MAX(IF(pa.fieldname = ''',
          fieldname,
          ''', pa.fieldvalue, NULL)) AS ',
          fieldname
        ) as output
    FROM
        product_additional
) as temp;

SET @sql = CONCAT('SELECT p.id
                    , p.name
                    , p.description, ', @sql, ' 
                   FROM product p
                   LEFT JOIN product_additional AS pa 
                    ON p.id = pa.id
                   GROUP BY p.id');

PREPARE stmt FROM @sql;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;

I started mongod in cmd,It threw error like C:\data\db\ not found. Created folder then typed mongod opened another cmd typed mongo it worked.

Its because either one of the Java versions(32 bit/64 bit) is missing from your computer. Try installing both the Jdks and run the code.
After installing the Jdks open R and type the code

system("java -version")

This will give you the version of Jdk installed. Then try loading the rJava package. This worked for me.

MDPI - 32px
HDPI - 48px
XHDPI- 64px

For each conflicted file you get, you can specify

git checkout --ours -- <paths>
# or
git checkout --theirs -- <paths>

From the git checkout docs

git checkout [-f|--ours|--theirs|-m|--conflict=<style>] [<tree-ish>] [--] <paths>...

--ours
--theirs
When checking out paths from the index, check out stage #2 (ours) or #3 (theirs) for unmerged paths.

The index may contain unmerged entries because of a previous failed merge. By default, if you try to check out such an entry from the index, the checkout operation will fail and nothing will be checked out. Using -f will ignore these unmerged entries. The contents from a specific side of the merge can be checked out of the index by using --ours or --theirs. With -m, changes made to the working tree file can be discarded to re-create the original conflicted merge result.

I tried everything on the post but nothing had worked. I then changed the .htaccess snippet that ErJab put up to read:

RewriteRule ^(.*)$ 'folder_name'/index.php/$1 [L]

The above line fixed it for me. where *folder_name* is the magento root folder.

Hope this helps!

Few ideas, in my opinion only first one gives some guarantee:

1. Keep your secrets on some server on internet, and when needed just grab them and use. If user is about to use dropbox then nothing stops you from making request to your site and get your secret key.

2. Put your secrets in jni code, add some variable code to make your libraries bigger and more difficult to decompile. You might also split key string in few parts and keep them in various places.

3. use obfuscator, also put in code hashed secret and later on unhash it when needed to use.

4. Put your secret key as last pixels of one of your image in assets. Then when needed read it in your code. Obfuscating your code should help hide code that will read it.

Another similar option that I think Nick briefly alluded to in the comments is to create multiple wrapper jars. I haven't tried it, but I think they could be completely empty other than the manifest file, which should specify the main class to load as well as the inclusion of the MyJar.jar to the classpath.

MyJar1.jar\META-INF\MANIFEST.MF

Manifest-Version: 1.0
Main-Class: com.mycomp.myproj.dir1.MainClass1
Class-Path: MyJar.jar

MyJar2.jar\META-INF\MANIFEST.MF

Manifest-Version: 1.0
Main-Class: com.mycomp.myproj.dir2.MainClass2
Class-Path: MyJar.jar

etc. Then just run it with java -jar MyJar2.jar

In addition to Felix's answer,

href={`/posts/${posts.id}`}

would work well too. This is nice because it's all in one string.

I had the same error problem using Code Blocks rev 13.12. I may be wrong here since I am less than a beginner :)

My problem was that I accidentally capitalized "M" in Main() instead of ALL lowercase = main() - once corrected, it worked!!!

I noticed that you have "int main()" instead of "main()". Is this the problem, or is it supposed to be that way?

Hope I could help...

split_part() does what you want in one step:

SELECT split_part(col, ',', 1) AS col1
     , split_part(col, ',', 2) AS col2
     , split_part(col, ',', 3) AS col3
     , split_part(col, ',', 4) AS col4
FROM   tbl;

Add as many lines as you have items in col (the possible maximum). Columns exceeding data items will be empty strings ('').

Have a look at this Stack Overflow answer.

 function getParameterByName(name, url) {
     if (!url) url = window.location.href;
     name = name.replace(/[\[\]]/g, "\\$&");
     var regex = new RegExp("[?&]" + name + "(=([^&#]*)|&|#|$)"),
         results = regex.exec(url);
     if (!results) return null;
     if (!results[2]) return '';
     return decodeURIComponent(results[2].replace(/\+/g, " "));
 }

You can use the method to animate:

I.e.:

var thequerystring = getParameterByName("location");
$('html,body').animate({scrollTop: $("div#" + thequerystring).offset().top}, 500);

For Rails 3.x and up:

With and ImageBox named "ImagePreview FormStrings.MyImageNames contains a regular get/set string cast method, which are linked to a scrollbox type list. The images have the same names as the linked names on the list, except for the .bmp endings. All bitmaps are dragged into the resources.resx

Bitmap myImage = (Bitmap)rm;
ImagePreview.Image = myImage;

This is another clean solution:

sub, sup {vertical-align: baseline; position: relative; font-size: 70%;} /* 70% size of its parent element font-size which is good. */
sub {bottom: -0.6em;} /* use em becasue they adapt to parent font-size */
sup {top: -0.6em;} /* use em becasue they adapt to parent font-size */

In this way you can still use sup/sub tags but you fixed their idious behavior to always screw up paragraph line height.

So now you can do:

  <p>This is a line of text.</p>
  <p>This is a line of text, <sub>with sub text.</sub></p>
  <p>This is a line of text, <sup>with sup text.</sup></p>
  <p>This is a line of text.</p>

And your paragraph line height should not get screwed up.

Tested on IE7, IE8, FF3.6, SAFARI4, CHROME5, OPERA9

I tested using a p {line-height: 1.3;} (that is a good line height unless you want your lines to stick too close) and it still works, cause "-0.6em" is such a small amount that also with that line height the sub/sub text will fit and don't go over each other.

Forgot a detail that might be relevant I always use DOCTYPE in the 1st line of my page (specifically I use the HTML 4.01 <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">). So I don't know if this solution works well when browser is in quirkmode (or not standard mode) due to lack of DOCTYPE or to a DOCTYPE that does not triggers Standard/Almost Standard mode.

axios.delete is passed a url and an optional configuration.

axios.delete(url[, config])

The fields available to the configuration can include the headers.

This makes it so that the API call can be written as:

}
const data = {

value_1, value_2, value_3: the values to be assigned to my_var according to the values of my_var

my_var: "{{ 'value_1' if VAR == 'param_1' else 'value_2' if VAR == 'param_2' else 'value_3' }}"

The problem is that if you redirect StandardOutput and/or StandardError the internal buffer can become full. Whatever order you use, there can be a problem:

• If you wait for the process to exit before reading StandardOutput the process can block trying to write to it, so the process never ends.
• If you read from StandardOutput using ReadToEnd then your process can block if the process never closes StandardOutput (for example if it never terminates, or if it is blocked writing to StandardError).

The solution is to use asynchronous reads to ensure that the buffer doesn't get full. To avoid any deadlocks and collect up all output from both StandardOutput and StandardError you can do this:

EDIT: See answers below for how avoid an ObjectDisposedException if the timeout occurs.

using (Process process = new Process())
{
    process.StartInfo.FileName = filename;
    process.StartInfo.Arguments = arguments;
    process.StartInfo.UseShellExecute = false;
    process.StartInfo.RedirectStandardOutput = true;
    process.StartInfo.RedirectStandardError = true;

    StringBuilder output = new StringBuilder();
    StringBuilder error = new StringBuilder();

    using (AutoResetEvent outputWaitHandle = new AutoResetEvent(false))
    using (AutoResetEvent errorWaitHandle = new AutoResetEvent(false))
    {
        process.OutputDataReceived += (sender, e) => {
            if (e.Data == null)
            {
                outputWaitHandle.Set();
            }
            else
            {
                output.AppendLine(e.Data);
            }
        };
        process.ErrorDataReceived += (sender, e) =>
        {
            if (e.Data == null)
            {
                errorWaitHandle.Set();
            }
            else
            {
                error.AppendLine(e.Data);
            }
        };

        process.Start();

        process.BeginOutputReadLine();
        process.BeginErrorReadLine();

        if (process.WaitForExit(timeout) &&
            outputWaitHandle.WaitOne(timeout) &&
            errorWaitHandle.WaitOne(timeout))
        {
            // Process completed. Check process.ExitCode here.
        }
        else
        {
            // Timed out.
        }
    }
}

I have seen JMS used in different commercial and academic projects. JMS can easily come into your picture, whenever you want to have a totally decoupled distributed systems. Generally speaking, when you need to send your request from one node, and someone in your network takes care of it without/with giving the sender any information about the receiver.

In my case, I have used JMS in developing a message-oriented middleware (MOM) in my thesis, where specific types of object-oriented objects are generated in one side as your request, and compiled and executed on the other side as your response.

If you are looking to do an exact match, use the following syntax: (param)?.

Eg.

<Route path={`my/(exact)?/path`} component={MyComponent} />

The nice thing about this is that you'll have props.match to play with, and you don't need to worry about checking the value of the optional parameter:

{ props: { match: { "0": "exact" } } }

Use the format() function:

>>> format(14, '#010b')
'0b00001110'

The format() function simply formats the input following the Format Specification mini language. The # makes the format include the 0b prefix, and the 010 size formats the output to fit in 10 characters width, with 0 padding; 2 characters for the 0b prefix, the other 8 for the binary digits.

This is the most compact and direct option.

If you are putting the result in a larger string, use an formatted string literal (3.6+) or use str.format() and put the second argument for the format() function after the colon of the placeholder {:..}:

>>> value = 14
>>> f'The produced output, in binary, is: {value:#010b}'
'The produced output, in binary, is: 0b00001110'
>>> 'The produced output, in binary, is: {:#010b}'.format(value)
'The produced output, in binary, is: 0b00001110'

As it happens, even for just formatting a single value (so without putting the result in a larger string), using a formatted string literal is faster than using format():

>>> import timeit
>>> timeit.timeit("f_(v, '#010b')", "v = 14; f_ = format")  # use a local for performance
0.40298633499332936
>>> timeit.timeit("f'{v:#010b}'", "v = 14")
0.2850222919951193

But I'd use that only if performance in a tight loop matters, as format(...) communicates the intent better.

If you did not want the 0b prefix, simply drop the # and adjust the length of the field:

>>> format(14, '08b')
'00001110'

You need to use an explicit color value (e.g. #000 or blue) for the color-property. none is invalid here. The initial value is browser-specific and cannot be restored using CSS. Keep in mind that there are some other pseudo-classes than :active, too.

First line of the error message describes the error type: "PDOException". The next line displays PDO::errorInfo, i.e:

1. SQLSTATE error code (a five characters alphanumeric identifier defined in the ANSI SQL standard).
2. Driver-specific error code.
3. Driver-specific error message.

• "HY000" is a general server error (see Server Error Codes and Messages in MySQL docs).
• "2002" is MySQL Client Error Code meaning "Can't connect to local MySQL server through socket" (see (Client Error Codes and Messages in MySQL docs).
• The driver specific error code and message ("php_network_getaddresses: getaddrinfo failed: Name or service not known") tell you that PDO is not able to resolve the host name.

The stack trace you attached, line 3, reveals that you did not specify the database connection parameters in the configuration file. The error show up when you test on local, right? You need to update /.env with the actual database connection parameters.

Setup IIS on the network server and change the path to http://server/path/to/file.txt

EDIT: Make sure you enable directory browsing in IIS

Check to find the root cause by reading logs in the tomcat installation log folder if all the above answers failed.Read the catalina.out file to find out the exact cause. It might be database credentials error or class definition not found.

There is also this:

select m from table where not regexp_like(m, '^[0-9]\d+$')

which selects the rows that contains characters from the column you want (which is m in the example but you can change).

Most of the combinations don't work properly in Oracle platforms but this does. Sharing for future reference.

For python3 on Ubuntu

 sudo apt-get install python3-setuptools

See the docs for the update command:

npm update [-g] [<pkg>...]

This command will update all the packages listed to the latest version (specified by the tag config), respecting semver.

Additionally, see the documentation on Node.js and NPM installation and Upgrading NPM.

The following original answer is from the old FAQ that no longer exists, but should work for Linux and Mac:

How do I update npm?

npm install -g npm

Please note that this command will remove your current version of npm. Make sure to use sudo npm install -g npm if on a Mac.

You can also update all outdated local packages by doing npm update without any arguments, or global packages by doing npm update -g.

Occasionally, the version of npm will progress such that the current version cannot be properly installed with the version that you have installed already. (Consider, if there is ever a bug in the update command.) In those cases, you can do this:

curl https://www.npmjs.com/install.sh | sh

To update Node.js itself, I recommend you use nvm, the Node Version Manager.

The best example of an abstract class is GenericServlet. GenericServlet is the parent class of HttpServlet. It is an abstract class.

When inheriting 'GenericServlet' in a custom servlet class, the service() method must be overridden.

Try this:

ggplot(data=dat, aes(x=Types, y=Number, fill=sample)) + 
     geom_bar(position = 'dodge', stat='identity') +
     geom_text(aes(label=Number), position=position_dodge(width=0.9), vjust=-0.25)

Edit Jan 6, 2017

I needed to keep double quotes in my configuration file so double escaping double quotes with sed helps:

render_template() {
  eval "echo \"$(sed 's/\"/\\\\"/g' $1)\""
}

I can't think of keeping trailing new lines, but empty lines in between are kept.

Although it is an old topic, IMO I found out more elegant solution here: http://pempek.net/articles/2013/07/08/bash-sh-as-template-engine/

#!/bin/sh

# render a template configuration file
# expand variables + preserve formatting
render_template() {
  eval "echo \"$(cat $1)\""
}

user="Gregory"
render_template /path/to/template.txt > path/to/configuration_file

These days I use the same approach as the answer described by @Behe below instead, updated link: https://stackoverflow.com/a/35292719/3423146 (old link: https://stackoverflow.com/a/35292719/1597808)

You can use the API in combination with depth, XPath, and wrapper arguments.

The following will query the API of the pluginManager to list all plugins installed, but only to return their shortName and version attributes. You can of course retrieve additional fields by adding '|' to the end of the XPath parameter and specifying the pattern to identify the node.

wget http://<jenkins>/pluginManager/api/xml?depth=1&xpath=/*/*/shortName|/*/*/version&wrapper=plugins

The wrapper argument is required in this case, because it's returning more than one node as part of the result, both in that it is matching multiple fields with the XPath and multiple plugin nodes.

It's probably useful to use the following URL in a browser to see what information on the plugins is available and then decide what you want to limit using XPath:

http://<jenkins>/pluginManager/api/xml?depth=1

The ... can only be used in JDK 1.5 or later. If you are using JDK 4 or lower, use this code:'

public static int[] addElement(int[] original, int newelement) {
    int[] nEw = new int[original.length + 1];
    System.arraycopy(original, 0, nEw, 0, original.length);
    nEw[original.length] = newelement;
}

otherwise (JDK 5 or higher):

public static int[] addElement(int[] original, int... elements) { // This can add multiple elements at once; addElement(int[], int) will still work though.
    int[] nEw = new int[original.length + elements.length];
    System.arraycopy(original, 0, nEw, 0, original.length);
    System.arraycopy(elements, 0, nEw, original.length, elements.length);
    return nEw;
}

Of course, as many have mentioned above, you could use a Collection or an ArrayList, which allows you to use the .add() method.

If anyone is looking for an updated correct syntax for this as I was, try the following:

Example:
dg.Rows[0].Cells[6].Value = "test";

UPDATE  table
SET     columnx = CASE WHEN condition THEN 25 ELSE columnx END,
        columny = CASE WHEN condition THEN columny ELSE 25 END

This exception happened when I forgot to close the connections

Perhaps this what you're looking for - https://www.w3schools.com/css/css3_flexbox.asp

  flex-wrap:               wrap;
  justify-content:         center;

  height:             150px;

In my opinion this is the simplest solution

$orderby = 'name';
                $order = 'asc';
                $hide_empty = false ;
                $cat_args = array(
                    'orderby'    => $orderby,
                    'order'      => $order,
                    'hide_empty' => $hide_empty,
                );

                $product_categories = get_terms( 'product_cat', $cat_args );

                if( !empty($product_categories) ){
                    echo '

                <ul>';
                    foreach ($product_categories as $key => $category) {
                        echo '

                <li>';
                        echo '<a href="'.get_term_link($category).'" >';
                        echo $category->name;
                        echo '</a>';
                        echo '</li>';
                    }
                    echo '</ul>

Another option is to use GitHub personal access tokens:

• Go to https://github.com/settings/tokens/new
• Add repo scope
• In Jenkins, add a GitHub source
• Use Repository HTTPS URL
• Add the HTTPS URL of the git repo (not the SSH one, eg. https://github.com/my-username/my-project.git)
• Add credential
  • Kind: Username with Password
  • Username: the GitHub username
  • Password: the personal access token you created on GitHub
  • ID: something like github-token-for-my-username

I tested this on Jenkins ver. 2.222.1 and Jenkins GitHub plugin 1.29.5 with a private GitHub repo.

As it was said you have a unique index.

However, when I added most of the list yesterday I didn't get this error once even though a lot of the entries I added yesterday have a blank cell in column 2 as well. Whats going on?

That means that all these entries contain value NULL, not empty string ''. Mysql lets you have multiple NULL values in unique fields.

this should help

Functions can be "passed" as function pointers, as per ISO C11 6.7.6.3p8: "A declaration of a parameter as ‘‘function returning type’’ shall be adjusted to ‘‘pointer to function returning type’’, as in 6.3.2.1. ". For example, this:

void foo(int bar(int, int));

is equivalent to this:

void foo(int (*bar)(int, int));

to answer to your second question - performance IS affected - if you are using those selectors with a single (no nested) ul:

<ul>
    <li>jjj</li>
    <li>jjj</li>    
    <li>jjj</li>
</ul>

the child selector ul > li is more performant than ul li because it is more specific. the browser traverse the dom "right to left", so when it finds a li it then looks for a any ul as a parent in the case of a child selector, while it has to traverse the whole dom tree to find any ul ancestors in case of the descendant selector

Try this:

CharSequence[] charArray = {"a","b","c"};

for (int i = 0; i < charArray.length; i++){
    String str = charArray.toString().join("", charArray[i]);
    System.out.print(str);
}

You may want to look at http://tug.ctan.org/tex-archive/macros/latex/contrib/float/ which allows you to define new floats using \newfloat

I say this because captions are usually applied to floats.

Straight ahead equations (those written with $ ... $, $$ ... $$, begin{equation}...) are in-line objects that do not support \caption.

This can be done using the following snippet just before \begin{document}

\usepackage{float}
\usepackage{aliascnt}
\newaliascnt{eqfloat}{equation}
\newfloat{eqfloat}{h}{eqflts}
\floatname{eqfloat}{Equation}

\newcommand*{\ORGeqfloat}{}
\let\ORGeqfloat\eqfloat
\def\eqfloat{%
  \let\ORIGINALcaption\caption
  \def\caption{%
    \addtocounter{equation}{-1}%
    \ORIGINALcaption
  }%
  \ORGeqfloat
}

and when adding an equation use something like

\begin{eqfloat}
\begin{equation}
f( x ) = ax + b
\label{eq:linear}
\end{equation}
\caption{Caption goes here}
\end{eqfloat}

DECLARE @MyFloat [float]

SET @MyFloat = 1000109360.050

SELECT REPLACE (RTRIM (REPLACE (REPLACE (RTRIM ((REPLACE (CAST (CAST (@MyFloat AS DECIMAL (38 ,18 )) AS VARCHAR( max)), '0' , ' '))), ' ' , '0'), '.', ' ')), ' ','.')

See: http://www.postgresql.org/docs/9.1/static/arrays.html

If your non-native driver still does not allow you to pass arrays, then you can:

• pass a string representation of an array (which your stored procedure can then parse into an array -- see string_to_array)

  CREATE FUNCTION my_method(TEXT) RETURNS VOID AS $$ 
  DECLARE
         ids INT[];
  BEGIN
         ids = string_to_array($1,',');
         ...
  END $$ LANGUAGE plpgsql;
  

  then

  SELECT my_method(:1)
  

  with :1 = '1,2,3,4'

• rely on Postgres itself to cast from a string to an array

  CREATE FUNCTION my_method(INT[]) RETURNS VOID AS $$ 
         ...
  END $$ LANGUAGE plpgsql;
  

  then

  SELECT my_method('{1,2,3,4}')
  

• choose not to use bind variables and issue an explicit command string with all parameters spelled out instead (make sure to validate or escape all parameters coming from outside to avoid SQL injection attacks.)

  CREATE FUNCTION my_method(INT[]) RETURNS VOID AS $$ 
         ...
  END $$ LANGUAGE plpgsql;
  

  then

  SELECT my_method(ARRAY [1,2,3,4])
  

the syntax is CONSTRAINT constraint_name PRIMARY KEY(col1,col2,col3) for example ::

CONSTRAINT pk_PersonID PRIMARY KEY (P_Id,LastName)

the above example will work if you are writting it while you are creating the table for example ::

CREATE TABLE person (
   P_Id int ,
   ............,
   ............,
   CONSTRAINT pk_PersonID PRIMARY KEY (P_Id,LastName)
);

to add this constraint to an existing table you need to follow the following syntax

ALTER TABLE table_name ADD CONSTRAINT constraint_name PRIMARY KEY (P_Id,LastName)

You can add setenv.sh in the the bin directory with:

export JAVA_HOME=$(readlink -f /usr/bin/java | sed "s:bin/java::")

and it will dynamically change when you update your packages.

I prefer using the following method:

system.webServer>
  <defaultDocument>
    <files>
      <clear />
      <add value="CreateThing.aspx" />
    </files>
  </defaultDocument>
</system.webServer>

If the string is at the beginning of the name, you can do this

$ compgen -f .bash
.bashrc
.bash_profile
.bash_prompt

• Xmlns means xml namespace.
• It is created to avoid naming conflicts in the xml’s.
• In order to avoid naming conflicts by any other way we need to provide each element with a prefix.
• to avoid repetitive usage of the prefix in each xml tag we use xmlns at the root of the xml. Hence we have the tag xmlns:android=”http://schemas.android.com/apk/res/android”
• Now android here simply means we are assigning the namespace “http://schemas.android.com/apk/res/android” to it.
• This namespace is not a URL but a URI also known as URN(universal resource name) which is rarely used in place of URI.
• Due to this android will be responsible to identify the android related elements in the xml document which would be android:xxxxxxx etc. Without this namespace android:xxxxxxx will be not recognized.

To put in layman’s term :

without xmlns:android=”http://schemas.android.com/apk/res/android” android related tags wont be recognized in the xml document of our layout.

If the select dropdown is read-only since birth and does not need to change at all, perhaps you should use another control instead? Like a simple <div> (plus hidden form field) or an <input type="text">?

Added: If the dropdown is not read-only all the time and JavaScript is used to enable/disable it, then this is still a solution - just modify the DOM on-the-fly.

Another way is to rename the following files:

1. Navigate your project directory.
2. Rename .git/refs/head/[branch-name] to .git/refs/head/new-branch-name.
3. Rename .git/refs/remotes/[all-remote-names]/[branch-name] to .git/refs/remotes/[all-remote-names]/new-branch-name.

Rename head and remotes both on your local PC and on origins(s)/remote server(s).

Branch is now renamed (local and remote!)

Attention

If your current branch-name contains slashes (/) Git will create the directories like so:

current branch-name: "awe/some/branch"

• .git/refs/head/awe/some/branch
• .git/refs/remotes/[all-remote-names]/awe/some/branch

wish branch-name: "new-branch-name"

1. Navigate your project directory.
2. Copy the branch file from .git/refs/*/awe/some/.
3. Put it in .git/refs/head/.
4. Copy the branch file from all of .git/refs/remotes/*/awe/some/.
5. Put them in .git/refs/remotes/*/.
6. Rename all copied branch files to new-branch-name.
7. Check if the directory and file structure now looks like this:

• .git/refs/head/new-branch-name
• .git/refs/remotes/[all-remote-names]/new-branch-name

8. Do the same on all your remote origins/servers (if they exist)

• Info: on remote-servers there are usually no refs/remotes/* directories because you're already on remote-server ;) (Well, maybe in advanced Git configurations it might be possible, but I have never seen that)

Branch is now renamed from awe/some/branch to new-branch-name (local and remote!)

Directories in branch-name got removed.

Information: This way might not be the best, but it still works for people who might have problems with the other ways

in your css file add this....

a:hover {
 cursor:pointer;
}

if you don't have a css file, add this to the HEAD of your HTML page

<style type="text/css">
 a:hover {
  cursor:pointer;
 }
</style>

also you can use the href="" attribute by returning false at the end of your javascript.

<a href="" onclick="doSomething(); return false;">a link</a>

this is good for many reasons. SEO or if people don't have javascript, the href="" will work. e.g.

<a href="nojavascriptpage.html" onclick="doSomething(); return false;">a link</a>

@see http://www.alistapart.com/articles/behavioralseparation

Edit: Worth noting @BalusC's answer where he mentions :hover is not necessary for the OP's use case. Although other style can be add with the :hover selector.

Here are the various Input Types as shown on the standard keyboard.

Setting the input type programmatically

editText.setInputType(InputType.TYPE_CLASS_TEXT);

Other options besides TYPE_CLASS_TEXT can be found in the documentation.

Setting the input type in XML

<EditText
    android:inputType="text"
/>

Other options besides text can be found in the documentation.

Supplemental code

Here is the code for the image above.

public class MainActivity extends AppCompatActivity {

        editText = findViewById(R.id.editText);
        textView = findViewById(R.id.textView);
        initArray();

Could it be a problem with past preview versions of Android Studio ? nowadays "beta" has replaced the "preview". I try it out step by step debugging while using Memory Monitor at same time by Android Studio (Beta) 0.8.11 on OSX 10.9.5 without any problems.

The tutorial Debugging with Android Studio also helps, specially this paragraph :

To track memory allocation of objects:

1. Start your app as described in Run Your App in Debug Mode.
2. Click Android to open the Android DDMS tool window.
3. On the Android DDMS tool window, select the Devices | logcat tab.
4. Select your device from the dropdown list.
5. Select your app by its package name from the list of running apps.
6. Click Start Allocation Tracking Interact with your app on the device. Click Stop Allocation Tracking

Here a couple of screenshot while debugging step by step on a breakpoint a monitoring the memory on the emulator:

First I tried this code

const peopleSchema = new mongoose.Schema({
  name: String,
  friends: [
    {
      firstName: String,
      lastName: String,
    },
  ],
});
const People = mongoose.model("person", peopleSchema);
const first = new Note({
  name: "Yash Salvi",
  notes: [
    {
      firstName: "Johnny",
      lastName: "Johnson",
    },
  ],
});
first.save();
const friendNew = {
  firstName: "Alice",
  lastName: "Parker",
};
People.findOneAndUpdate(
  { name: "Yash Salvi" },
  { $push: { friends: friendNew } },
  function (error, success) {
    if (error) {
      console.log(error);
    } else {
      console.log(success);
    }
  }
);

But I noticed that only first friend (i.e. Johhny Johnson) gets saved and the objective to push array element in existing array of "friends" doesn't seem to work as when I run the code , in database in only shows "First friend" and "friends" array has only one element ! So the simple solution is written below

const peopleSchema = new mongoose.Schema({
  name: String,
  friends: [
    {
      firstName: String,
      lastName: String,
    },
  ],
});
const People = mongoose.model("person", peopleSchema);
const first = new Note({
  name: "Yash Salvi",
  notes: [
    {
      firstName: "Johnny",
      lastName: "Johnson",
    },
  ],
});
first.save();
const friendNew = {
  firstName: "Alice",
  lastName: "Parker",
};
People.findOneAndUpdate(
  { name: "Yash Salvi" },
  { $push: { friends: friendNew } },
  { upsert: true }
);

Adding "{ upsert: true }" solved problem in my case and once code is saved and I run it , I see that "friends" array now has 2 elements ! The upsert = true option creates the object if it doesn't exist. default is set to false.

if it doesn't work use below snippet

People.findOneAndUpdate(
  { name: "Yash Salvi" },
  { $push: { friends: friendNew } },
).exec();

For expect, .equal will compare objects rather than their data, and in your case it is two different arrays.

Use .eql in order to deeply compare values. Check out this link.
Or you could use .deep.equal in order to simulate same as .eql.
Or in your case you might want to check .members.

For asserts you can use .deepEqual, link.

note for php 7 users, add this to your httpd.conf file:

# PHP 7 specific configuration
<IfModule php7_module>
    AddType application/x-httpd-php .php
    AddType application/x-httpd-php-source .phps
    <IfModule dir_module>
        DirectoryIndex index.html index.php
    </IfModule>
</IfModule>

You can try one of the following methods:

rebase

For simple changes try rebasing on top of it while pulling the changes, e.g.

git pull origin master -r

So it'll apply your current branch on top of the upstream branch after fetching.

This is equivalent to: checkout master, fetch and rebase origin/master git commands.

This is a potentially dangerous mode of operation. It rewrites history, which does not bode well when you published that history already. Do not use this option unless you have read git-rebase(1) carefully.

checkout

If you don't care about your local changes, you can switch to other branch temporary (with force), and switch it back, e.g.

git checkout origin/master -f
git checkout master -f

reset

If you don't care about your local changes, try to reset it to HEAD (original state), e.g.

git reset HEAD --hard

If above won't help, it may be rules in your git normalization file (.gitattributes) so it's better to commit what it says. Or your file system doesn't support permissions, so you've to disable filemode in your git config.

I had the same problem. I made a button in the storyboard and connected it to the ViewController, and then later on deleted the button. So the connection was still there, but the button was not, and so I got the same error as you.

To Fix:

Go to the connection inspector (the arrow in the top right corner, in your storyboard), and delete any unused connections.

You can do it in a single command:

git fetch --all && git reset --hard origin/master

Or in a pair of commands:

git fetch --all
git reset --hard origin/master

Note than you will lose ALL your local changes

You could always construct the #temp table in dynamic SQL. For example, right now I guess you have been trying:

CREATE TABLE #tmp(a INT, b INT, c INT);

DECLARE @sql NVARCHAR(1000);

SET @sql = N'BULK INSERT #tmp ...' + @variables;

EXEC master.sys.sp_executesql @sql;

SELECT * FROM #tmp;

This makes it tougher to maintain (readability) but gets by the scoping issue:

DECLARE @sql NVARCHAR(MAX);

SET @sql = N'CREATE TABLE #tmp(a INT, b INT, c INT);

BULK INSERT #tmp ...' + @variables + ';

SELECT * FROM #tmp;';

EXEC master.sys.sp_executesql @sql;

EDIT 2011-01-12

In light of how my almost 2-year old answer was suddenly deemed incomplete and unacceptable, by someone whose answer was also incomplete, how about:

CREATE TABLE #outer(a INT, b INT, c INT);

DECLARE @sql NVARCHAR(MAX);

SET @sql = N'SET NOCOUNT ON; 

CREATE TABLE #inner(a INT, b INT, c INT);

BULK INSERT #inner ...' + @variables + ';

SELECT * FROM #inner;';

INSERT #outer EXEC master.sys.sp_executesql @sql;

Open the key file in Notepad++ and verify the encoding. If it says UTF-8-BOM then change it to UTF-8. Save the file and try again.

simply use delete, but be aware that you should read fully what the effects are of using this:

 delete object.index; //true
 object.index; //undefined

but if I was to use like so:

var x = 1; //1
delete x; //false
x; //1

but if you do wish to delete variables in the global namespace, you can use it's global object such as window, or using this in the outermost scope i.e

var a = 'b';
delete a; //false
delete window.a; //true
delete this.a; //true

http://perfectionkills.com/understanding-delete/

another fact is that using delete on an array will not remove the index but only set the value to undefined, meaning in certain control structures such as for loops, you will still iterate over that entity, when it comes to array's you should use splice which is a prototype of the array object.

Example Array:

var myCars=new Array();
myCars[0]="Saab";
myCars[1]="Volvo";
myCars[2]="BMW";

if I was to do:

delete myCars[1];

the resulting array would be:

["Saab", undefined, "BMW"]

but using splice like so:

myCars.splice(1,1);

would result in:

["Saab", "BMW"]

Make it simple:

render(<BrowserRouter><Main /></BrowserRouter>, document.getElementById('root'));

and don't forget: import { BrowserRouter } from "react-router-dom";

If you want to display a single character then you can also use name[0] instead of using pointer.

It will serve your purpose but if you want to display full string using %c, you can try this:

#include<stdio.h>
void main()
{ 
    char name[]="siva";
    int i;
    for(i=0;i<4;i++)
    {
        printf("%c",*(name+i));
    }
} 

They have already answered how to use a global variable.

I will tell you why the use of global variables is a bad idea as a result of this question carried out in stackoverflow in Spanish.

Explicit translation of the text in Spanish:

Impact of the change

The problem with global variables is that they create hidden dependencies. When it comes to large applications, you yourself do not know / remember / you are clear about the objects you have and their relationships.

So, you can not have a clear notion of how many objects your global variable is using. And if you want to change something of the global variable, for example, the meaning of each of its possible values, or its type? How many classes or compilation units will that change affect? If the amount is small, it may be worth making the change. If the impact will be great, it may be worth looking for another solution.

But what is the impact? Because a global variable can be used anywhere in the code, it can be very difficult to measure it.

In addition, always try to have a variable with the shortest possible life time, so that the amount of code that makes use of that variable is the minimum possible, and thus better understand its purpose, and who modifies it.

A global variable lasts for the duration of the program, and therefore, anyone can use the variable, either to read it, or even worse, to change its value, making it more difficult to know what value the variable will have at any given program point. .

Order of destruction

Another problem is the order of destruction. Variables are always destroyed in reverse order of their creation, whether they are local or global / static variables (an exception is the primitive types, int,enums, etc., which are never destroyed if they are global / static until they end the program).

The problem is that it is difficult to know the order of construction of the global (or static) variables. In principle, it is indeterminate.

If all your global / static variables are in a single compilation unit (that is, you only have a .cpp), then the order of construction is the same as the writing one (that is, variables defined before, are built before).

But if you have more than one .cpp each with its own global / static variables, the global construction order is indeterminate. Of course, the order in each compilation unit (each .cpp) in particular, is respected: if the global variableA is defined before B,A will be built before B, but It is possible that between A andB variables of other .cpp are initialized. For example, if you have three units with the following global / static variables:

Image1

In the executable it could be created in this order (or in any other order as long as the relative order is respected within each .cpp):

Image2

Why is this important? Because if there are relations between different static global objects, for example, that some use others in their destructors, perhaps, in the destructor of a global variable, you use another global object from another compilation unit that turns out to be already destroyed ( have been built later).

Hidden dependencies and * test cases *

I tried to find the source that I will use in this example, but I can not find it (anyway, it was to exemplify the use of singletons, although the example is applicable to global and static variables). Hidden dependencies also create new problems related to controlling the behavior of an object, if it depends on the state of a global variable.

Imagine you have a payment system, and you want to test it to see how it works, since you need to make changes, and the code is from another person (or yours, but from a few years ago). You open a new main, and you call the corresponding function of your global object that provides a bank payment service with a card, and it turns out that you enter your data and they charge you. How, in a simple test, have I used a production version? How can I do a simple payment test?

After asking other co-workers, it turns out that you have to "mark true", a global bool that indicates whether we are in test mode or not, before beginning the collection process. Your object that provides the payment service depends on another object that provides the mode of payment, and that dependency occurs in an invisible way for the programmer.

In other words, the global variables (or singletones), make it impossible to pass to "test mode", since global variables can not be replaced by "testing" instances (unless you modify the code where said code is created or defined). global variable, but we assume that the tests are done without modifying the mother code).

Solution

This is solved by means of what is called * dependency injection *, which consists in passing as a parameter all the dependencies that an object needs in its constructor or in the corresponding method. In this way, the programmer ** sees ** what has to happen to him, since he has to write it in code, making the developers gain a lot of time.

If there are too many global objects, and there are too many parameters in the functions that need them, you can always group your "global objects" into a class, style * factory *, that builds and returns the instance of the "global object" (simulated) that you want , passing the factory as a parameter to the objects that need the global object as dependence.

If you pass to test mode, you can always create a testing factory (which returns different versions of the same objects), and pass it as a parameter without having to modify the target class.

But is it always bad?

Not necessarily, there may be good uses for global variables. For example, constant values ??(the PI value). Being a constant value, there is no risk of not knowing its value at a given point in the program by any type of modification from another module. In addition, constant values ??tend to be primitive and are unlikely to change their definition.

It is more convenient, in this case, to use global variables to avoid having to pass the variables as parameters, simplifying the signatures of the functions.

Another can be non-intrusive "global" services, such as a logging class (saving what happens in a file, which is usually optional and configurable in a program, and therefore does not affect the application's nuclear behavior), or std :: cout,std :: cin or std :: cerr, which are also global objects.

Any other thing, even if its life time coincides almost with that of the program, always pass it as a parameter. Even the variable could be global in a module, only in it without any other having access, but that, in any case, the dependencies are always present as parameters.

To disable resizing completely:

textarea {
    resize: none;
}

To allow only vertical resizing:

textarea {
    resize: vertical;
}

To allow only horizontal resizing:

textarea {
    resize: horizontal;
}

Or you can limit size:

textarea {
    max-width: 100px; 
    max-height: 100px;
}

To limit size to parents width and/or height:

textarea {
    max-width: 100%; 
    max-height: 100%;
}

Another scenario that you can get the [: too many arguments or [: a: binary operator expected errors is if you try to test for all arguments "$@"

if [ -z "$@" ]
then
    echo "Argument required."
fi

It works correctly if you call foo.sh or foo.sh arg1. But if you pass multiple args like foo.sh arg1 arg2, you will get errors. This is because it's being expanded to [ -z arg1 arg2 ], which is not a valid syntax.

The correct way to check for existence of arguments is [ "$#" -eq 0 ]. ($# is the number of arguments).

You're already prepending the hash sign in your showDialog() function, and you're missing single quotes in your second code snippet. You should also return false from the handler to prevent a postback from occurring. Try:

<asp:Button ID="ButtonAdd" runat="server" Text="Add"
    OnClientClick="showDialog('<%=addPerson.ClientID %>'); return false;" />

      result.append(line);
                System.out.println(line);
    }

   }
 }

You can also get this error if the objects you're passing to the method are out of order. In other words say your method takes, in order, a string, an integer, and a date. If you pass a date, then a string, then an integer you will get the same error message.

If anaconda is fully updated, a simple "conda init zsh" should work. Navigate into the anaconda3 folder using

cd /path/to/anaconda3/

of course replacing "/path/to/anaconda/" with "~/anaconda3" or "/anaconda3" or wherever the "anaconda3" folder is kept.

To make sure it's updated, run

./bin/conda update --prefix . anaconda

After this, running

./bin/conda init zsh

(or whatever shell you're using) will finish the job cleanly.

If using 3rd Pary Libaries is ok cyclops-react defines Lazy extended collections with this functionality built in. For example we could simply write

ListX myListToParse;

ListX myFinalList = myListToParse.filter(elt -> elt != null) .map(elt -> doSomething(elt));

myFinalList is not evaluated until first access (and there after the materialized list is cached and reused).

I took hhafez code and added a memory test:

private static void test() {
    Runtime runtime = Runtime.getRuntime();
    long memory;
    ...
    memory = runtime.freeMemory();
    // for loop code
    memory = memory-runtime.freeMemory();

I run this separately for each approach, the '+' operator, String.format and StringBuilder (calling toString()), so the memory used will not be affected by other approaches. I added more concatenations, making the string as "Blah" + i + "Blah"+ i +"Blah" + i + "Blah".

The result are as follow (average of 5 runs each):
Approach       Time(ms)  Memory allocated (long)
'+' operator     747           320,504
String.format  16484       373,312
StringBuilder  769           57,344

We can see that String '+' and StringBuilder are practically identical time-wise, but StringBuilder is much more efficient in memory use. This is very important when we have many log calls (or any other statements involving strings) in a time interval short enough so the Garbage Collector won't get to clean the many string instances resulting of the '+' operator.

And a note, BTW, don't forget to check the logging level before constructing the message.

Conclusions:

1. I'll keep on using StringBuilder.
2. I have too much time or too little life.

1. Why does the getOne(id) method fail?

See this section in the docs. You overriding the already in place transaction might be causing the issue. However, without more info this one is difficult to answer.

2. When I should use the getOne(id) method?

Without digging into the internals of Spring Data JPA, the difference seems to be in the mechanism used to retrieve the entity.

If you look at the JavaDoc for getOne(ID) under See Also:

See Also:
EntityManager.getReference(Class, Object)

it seems that this method just delegates to the JPA entity manager's implementation.

However, the docs for findOne(ID) do not mention this.

The clue is also in the names of the repositories. JpaRepository is JPA specific and therefore can delegate calls to the entity manager if so needed. CrudRepository is agnostic of the persistence technology used. Look here. It's used as a marker interface for multiple persistence technologies like JPA, Neo4J etc.

So there's not really a 'difference' in the two methods for your use cases, it's just that findOne(ID) is more generic than the more specialised getOne(ID). Which one you use is up to you and your project but I would personally stick to the findOne(ID) as it makes your code less implementation specific and opens the doors to move to things like MongoDB etc. in the future without too much refactoring :)

Some background: I went looking for exactly this question because I had to do something to retrieve content, but all I had available was an old version of python with inadequate SSL support. If you're on an older MacBook, you know what I'm talking about. In any case, curl runs fine from a shell (I suspect it has modern SSL support linked in) so sometimes you want to do this without using requests or urllib2.

You can use the subprocess module to execute curl and get at the retrieved content:

import subprocess

// 'response' contains a []byte with the retrieved content.
// use '-s' to keep curl quiet while it does its job, but
// it's useful to omit that while you're still writing code
// so you know if curl is working
response = subprocess.check_output(['curl', '-s', baseURL % page_num])

Python 3's subprocess module also contains .run() with a number of useful options. I'll leave it to someone who is actually running python 3 to provide that answer.

You didn't mention how your backup was made, so the generic answer is: Usually with the psql tool.

Depending on what pg_dump was instructed to dump, the SQL file can have different sets of SQL commands. For example, if you instruct pg_dump to dump a database using --clean and --schema-only, you can't expect to be able to restore the database from that dump as there will be no SQL commands for COPYing (or INSERTing if --inserts is used ) the actual data in the tables. A dump like that will contain only DDL SQL commands, and will be able to recreate the schema but not the actual data.

A typical SQL dump is restored with psql:

psql (connection options here) database  < yourbackup.sql

or alternatively from a psql session,

psql (connection options here) database
database=# \i /path/to/yourbackup.sql

In the case of backups made with pg_dump -Fc ("custom format"), which is not a plain SQL file but a compressed file, you need to use the pg_restore tool.

If you're working on a unix-like, try this:

man psql
man pg_dump
man pg_restore

otherwise, take a look at the html docs. Good luck!

A 32-bit float has about 7 digits of precision and a 64-bit double has about 16 digits of precision

Long answer:

Floating-point numbers have three components:

1. A sign bit, to determine if the number is positive or negative.
2. An exponent, to determine the magnitude of the number.
3. A fraction, which determines how far between two exponent values the number is. This is sometimes called “the significand, mantissa, or coefficient”

Essentially, this works out to sign * 2^exponent * (1 + fraction). The “size” of the number, it’s exponent, is irrelevant to us, because it only scales the value of the fraction portion. Knowing that log10(n) gives the number of digits of n,† we can determine the precision of a floating point number with log10(largest_possible_fraction). Because each bit in a float stores 2 possibilities, a binary number of n bits can store a number up to 2n - 1 (a total of 2n values where one of the values is zero). This gets a bit hairier, because it turns out that floating point numbers are stored with one less bit of fraction than they can use, because zeroes are represented specially and all non-zero numbers have at least one non-zero binary bit.‡

Combining this, the digits of precision for a floating point number is log10(2n), where n is the number of bits of the floating point number’s fraction. A 32-bit float has 24 bits of fraction for ˜7.22 decimal digits of precision, and a 64-bit double has 53 bits of fraction for ˜15.95 decimal digits of precision.

For more on floating point accuracy, you might want to read about the concept of a machine epsilon.

† For n = 1 at least — for other numbers your formula will look more like ?log10(|n|)? + 1.

‡ “This rule is variously called the leading bit convention, the implicit bit convention, or the hidden bit convention.” (Wikipedia)

This may be helpful for all using tools for GIT

Command

Switch branch - it will move your changes to new-branch. Then you can commit changes.

 $ git checkout -b <new-branch>

TortoiseGIT

Right-click on your repository and then use TortoiseGit->Switch/Checkout

SourceTree

Use the "Checkout" button to switch branch. You will see the "checkout" button at the top after clicking on a branch. Changes from the current branch will be applied automatically. Then you can commit them.

As TokenMacGuy says, you should use thread.is_alive() to check if a thread is still running. To remove no longer running threads from your list you can use a list comprehension:

for t in my_threads:
    if not t.is_alive():
        # get results from thread
        t.handled = True
my_threads = [t for t in my_threads if not t.handled]

This avoids the problem of removing items from a list while iterating over it.

If you simply need to get the basic snapshot of the files + folders. Follow these baby steps:

• Press Windows + R
• Press Enter
• Type cmd
• Press Enter
• Type dir -s
• Press Enter

If you just want to convert a string to be available for download you can try this using jQuery.

$('a.download').attr('href', 'data:application/csv;charset=utf-8,' + encodeURI(data));

That is how I make it work :

In Linux (Ubuntu 16.04)

sudo apt-get install default-jre
sudo apt-get install default-jdk
sudo R CMD javareconf

in R:

install.packages("rJava")

As of python 3.5+:

@functools.wraps(f)
def g():
    pass

Is an alias for g = functools.update_wrapper(g, f). It does exactly three things:

• it copies the __module__, __name__, __qualname__, __doc__, and __annotations__ attributes of f on g. This default list is in WRAPPER_ASSIGNMENTS, you can see it in the functools source.
• it updates the __dict__ of g with all elements from f.__dict__. (see WRAPPER_UPDATES in the source)
• it sets a new __wrapped__=f attribute on g

The consequence is that g appears as having the same name, docstring, module name, and signature than f. The only problem is that concerning the signature this is not actually true: it is just that inspect.signature follows wrapper chains by default. You can check it by using inspect.signature(g, follow_wrapped=False) as explained in the doc. This has annoying consequences:

• the wrapper code will execute even when the provided arguments are invalid.
• the wrapper code can not easily access an argument using its name, from the received *args, **kwargs. Indeed one would have to handle all cases (positional, keyword, default) and therefore to use something like Signature.bind().

Now there is a bit of confusion between functools.wraps and decorators, because a very frequent use case for developing decorators is to wrap functions. But both are completely independent concepts. If you're interested in understanding the difference, I implemented helper libraries for both: decopatch to write decorators easily, and makefun to provide a signature-preserving replacement for @wraps. Note that makefun relies on the same proven trick than the famous decorator library.

Here it is:

def put4ChannelImageOn4ChannelImage(back, fore, x, y):
    rows, cols, channels = fore.shape    
    trans_indices = fore[...,3] != 0 # Where not transparent
    overlay_copy = back[y:y+rows, x:x+cols] 
    overlay_copy[trans_indices] = fore[trans_indices]
    back[y:y+rows, x:x+cols] = overlay_copy

#test
background = np.zeros((1000, 1000, 4), np.uint8)
background[:] = (127, 127, 127, 1)
overlay = cv2.imread('imagee.png', cv2.IMREAD_UNCHANGED)
put4ChannelImageOn4ChannelImage(background, overlay, 5, 5)

foundElement = myArray[myArray.findIndex(element => //condition here)];

This should works:

Step1:

defaultConfig {
    applicationId "service.ingreens.com.gpsautoon"
    minSdkVersion 17
    targetSdkVersion 25
    versionCode 1
    versionName "1.0"
    multiDexEnabled true
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}

Step 2:

compile 'com.android.support:multidex:1.0.1'

Step 3: Take another class

public class MyApplication extends MultiDexApplication {
}

Step 4: Add this line on manifest

<application
    android:name="android.support.multidex.MultiDexApplication">
</application>

Can't upvote so I'll repost @jfs comment cause I think it should be more visible.

@AnneTheAgile: shell=True is not required. Moreover you should not use it unless it is necessary (see @ valid's comment). You should pass each command-line argument as a separate list item instead e.g., use ['command', 'arg 1', 'arg 2'] instead of "command 'arg 1' 'arg 2'". – jfs Mar 3 '15 at 10:02

Try this code, I get working fine.

 webSettings.setSupportZoom(true);
 webSettings.setBuiltInZoomControls(true);
 webSettings.setDisplayZoomControls(false);

using Guava:

Multimap<String,String> parseQueryString(String queryString, String encoding) {
    LinkedListMultimap<String, String> result = LinkedListMultimap.create();

    for(String entry : Splitter.on("&").omitEmptyStrings().split(queryString)) {
        String pair [] = entry.split("=", 2);
        try {
            result.put(URLDecoder.decode(pair[0], encoding), pair.length == 2 ? URLDecoder.decode(pair[1], encoding) : null);
        } catch (UnsupportedEncodingException e) {
            throw new RuntimeException(e);
        }
    }

    return result;
}

I found this question while researching a very similar problem. My solution is to split the problem into two parts. First, you need to capture the data that you want to associate with the class methods. In this case, handler_for will associate a Unix command with handler for that command's output.

class OutputAnalysis(object):
    "analyze the output of diagnostic commands"
    def handler_for(name):
        "decorator to associate a function with a command"
        def wrapper(func):
            func.handler_for = name
            return func
        return wrapper
    # associate mount_p with 'mount_-p.txt'
    @handler_for('mount -p')
    def mount_p(self, slurped):
        pass

Now that we've associated some data with each class method, we need to gather that data and store it in a class attribute.

OutputAnalysis.cmd_handler = {}
for value in OutputAnalysis.__dict__.itervalues():
    try:
        OutputAnalysis.cmd_handler[value.handler_for] = value
    except AttributeError:
        pass

To upload you file along with parameters.

NOTE : put this code below in non-ui-thread to get response.

String charset = "UTF-8";
String requestURL = "YOUR_URL";

MultipartUtility multipart = new MultipartUtility(requestURL, charset);
multipart.addFormField("param_name_1", "param_value");
multipart.addFormField("param_name_2", "param_value");
multipart.addFormField("param_name_3", "param_value");
multipart.addFilePart("file_param_1", new File(file_path));
String response = multipart.finish(); // response from server.

Add a CommandName attribute, and optionally a CommandArgument attribute, to your LinkButton control. Then set the OnCommand attribute to the name of your Command event handler.

<asp:LinkButton ID="ENameLinkBtn" runat="server" CommandName="MyValueGoesHere" CommandArgument="OtherValueHere" 
          style="font-weight: 700; font-size: 8pt;" OnCommand="ENameLinkBtn_Command" ><%# Eval("EName") %></asp:LinkButton>

<asp:Label id="Label1" runat="server"/>

Then it will be available when in your handler:

protected void ENameLinkBtn_Command (object sender, CommandEventArgs e)
{
   Label1.Text = "You chose: " + e.CommandName + " Item " + e.CommandArgument;
}

More info on MSDN

something like this should work...

String name = "Test2";//Name of the class
        Class myClass = Class.forName(name);
        Object o = myClass.newInstance();

You're looking for RAISERROR.

From MSDN:

Generates an error message and initiates error processing for the session. RAISERROR can either reference a user-defined message stored in the sys.messages catalog view or build a message dynamically. The message is returned as a server error message to the calling application or to an associated CATCH block of a TRY…CATCH construct.

CodeProject has a good article that also describes in-depth the details of how it works and how to use it.

Calling toDate will create a copy (the documentation is down-right wrong about it not being a copy), of the underlying JS Date object. JS Date object is stored in UTC and will always print to eastern time. Without getting into whether .utc() modifies the underlying object that moment wraps use the code below.

You don't need moment for this.

new Date().getTime()

This works, because JS Date at its core is in UTC from the Unix Epoch. It's extraordinarily confusing and I believe a big flaw in the interface to mix local and UTC times like this with no descriptions in the methods.

You can also try another library - https://github.com/wikimedia/jquery.i18n .

In addition to parameter replacement and multiple plural forms, it has support for gender a rather unique feature of custom grammar rules that some languages need.

You're using an Array like an "associative array", which does not exist in JavaScript. Use an Object ({}) instead.

If you are going to continue with an array, realize that toString() will join all the numbered properties together separated by a comma. (the same as .join(",")).

Properties like a and b will not come up using this method because they are not in the numeric indexes. (ie. the "body" of the array)

In JavaScript, Array inherits from Object, so you can add and delete properties on it like any other object. So for an array, the numbered properties (they're technically just strings under the hood) are what counts in methods like .toString(), .join(), etc. Your other properties are still there and very much accessible. :)

Read Mozilla's documentation for more information about Arrays.

var aa = [];

// these are now properties of the object, but not part of the "array body"
aa.a = "A";
aa.b = "B";

// these are part of the array's body/contents
aa[0] = "foo";
aa[1] = "bar";

aa.toString(); // most browsers will say "foo,bar" -- the same as .join(",")

This will open the URL in Safari:

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"http://www.facebook.com/comments.php?href=http://wombeta.jiffysoftware.com/ViewWOMPrint.aspx?WPID=317"]];

For the iphone, you can launch the Facebook app if installed by using a url starting with fb://

More information can be found here: http://iphonedevtools.com/?p=302 also here: http://wiki.akosma.com/IPhone_URL_Schemes#Facebook

Stolen from the above site:

fb://profile – Open Facebook app to the user’s profile
fb://friends – Open Facebook app to the friends list
fb://notifications – Open Facebook app to the notifications list (NOTE: there appears to be a bug with this URL. The Notifications page opens. However, it’s not possible to navigate to anywhere else in the Facebook app)
fb://feed – Open Facebook app to the News Feed
fb://events – Open Facebook app to the Events page
fb://requests – Open Facebook app to the Requests list
fb://notes - Open Facebook app to the Notes page
fb://albums – Open Facebook app to Photo Albums list

To launch the above URLs:

NSURL *theURL = [NSURL URLWithString:@"fb://<insert function here>"];
[[UIApplication sharedApplication] openURL:theURL];

As you did not mention which OS you are running, here a solution for linux: use losetup

losetup /dev/loop0 /path/to/your/file.img

Then you can mount it.

A variation of the function provided by Paolo Bergantino that works directly on String:

String.prototype.addSlashes = function() 
{ 
   //no need to do (str+'') anymore because 'this' can only be a string
   return this.replace(/[\\"']/g, '\\$&').replace(/\u0000/g, '\\0');
} 

By adding the code above in your library you will be able to do:

var test = "hello single ' double \" and slash \\ yippie";
alert(test.addSlashes());

EDIT:

Following suggestions in the comments, whoever is concerned about conflicts amongst JavaScript libraries can add the following code:

if(!String.prototype.addSlashes)
{
   String.prototype.addSlashes = function()... 
}
else
   alert("Warning: String.addSlashes has already been declared elsewhere.");

You can't wait() on an object unless the current thread owns that object's monitor. To do that, you must synchronize on it:

class Runner implements Runnable
{
  public void run()
  {
    try
    {
      synchronized(Main.main) {
        Main.main.wait();
      }
    } catch (InterruptedException e) {}
    System.out.println("Runner away!");
  }
}

The same rule applies to notify()/notifyAll() as well.

The Javadocs for wait() mention this:

This method should only be called by a thread that is the owner of this object's monitor. See the notify method for a description of the ways in which a thread can become the owner of a monitor.

Throws:

IllegalMonitorStateException – if the current thread is not the owner of this object's monitor.

And from notify():

A thread becomes the owner of the object's monitor in one of three ways:

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

Here's a custom IEnumerable<> extension method that can be used to loop through two lists simultaneously.

As you say, local variables and references are stored on the stack. When a method returns, the stack pointer is simply moved back to where it was before the method started, that is, all local data is "removed from the stack". Therefore, there is no garbage collection needed on the stack, that only happens in the heap.

To answer your specific questions:

• See this question on how to increase the stack size.
• You can limit the stack growth by:
  • grouping many local variables in an object: that object will be stored in the heap and only the reference is stored on the stack
  • limit the number of nested function calls (typically by not using recursion)
• For windows, the default stack size is 320k for 32bit and 1024k for 64bit, see this link.

SQL> alter session set "_ORACLE_SCRIPT"=true;  
SQL> create user sec_admin identified by "Chutinhbk123@!";

This algorithm in Python gets you part of the way there.

Tell me what happens if the windows is a funny size.

Maybe what you should have is a list of all acceptable ratios (to the 3rd party component). Then, find the closest match to your window and return that ratio from the list.

The latest version of SSPI (bundled with Windows 7) has an implementation of TLS 1.2, which can be found in schannel.dll

As Mark C points out, you can use the MSXML Base64 encoding functionality as described here.

I prefer late binding because it's easier to deploy, so here's the same function that will work without any VBA references:

Function EncodeBase64(text As String) As String
  Dim arrData() As Byte
  arrData = StrConv(text, vbFromUnicode)

  Dim objXML As Variant
  Dim objNode As Variant

  Set objXML = CreateObject("MSXML2.DOMDocument")
  Set objNode = objXML.createElement("b64")

  objNode.dataType = "bin.base64"
  objNode.nodeTypedValue = arrData
  EncodeBase64 = objNode.text

  Set objNode = Nothing
  Set objXML = Nothing
End Function

This is from the msdn article here:

https://blogs.msdn.microsoft.com/tomarcher/2006/05/10/are-hash-codes-unique/

"While you will hear people state that hash codes generate a unique value for a given input, the fact is that, while difficult to accomplish, it is technically feasible to find two different data inputs that hash to the same value. However, the true determining factors regarding the effectiveness of a hash algorithm lie in the length of the generated hash code and the complexity of the data being hashed."

So just use a hash algorithm suitable to your data size and it will have unique hashcodes.

eval() is not necessary. This will work fine:

var date = new Date(parseInt(jsonDate.substr(6)));

The substr() function takes out the /Date( part, and the parseInt() function gets the integer and ignores the )/ at the end. The resulting number is passed into the Date constructor.

I have intentionally left out the radix (the 2nd argument to parseInt); see my comment below.

Also, I completely agree with Rory's comment: ISO-8601 dates are preferred over this old format - so this format generally shouldn't be used for new development. See the excellent Json.NET library for a great alternative that serializes dates using the ISO-8601 format.

For ISO-8601 formatted JSON dates, just pass the string into the Date constructor:

var date = new Date(jsonDate); //no ugly parsing needed; full timezone support

SQL Server 2012 and up support LAG / LEAD functions to access the previous or subsequent row. SQL Server 2005 does not support this (in SQL2005 you need a join or something else).

A SQL 2012 example on this data

/* Prepare */
select * into #tmp
from
(
    select 2  as rowint,      23 as Value
    union select 3,       45
    union select 17,      10
    union select 9,       0
) x


/* The SQL 2012 query */
select rowInt, Value, LEAD(value) over (order by rowInt) - Value  
from #tmp

LEAD(value) will return the value of the next row in respect to the given order in "over" clause.

Fast and easy with HAVING:

SELECT * FROM tblpm n 
FROM tblpm GROUP BY control_number 
HAVING date_updated=MAX(date_updated);

In the context of HAVING, MAX finds the max of each group. Only the latest entry in each group will satisfy date_updated=max(date_updated). If there's a tie for latest within a group, both will pass the HAVING filter, but GROUP BY means that only one will appear in the returned table.

Why it does not work

There is no datetime dtype to be set for read_csv as csv files can only contain strings, integers and floats.

Setting a dtype to datetime will make pandas interpret the datetime as an object, meaning you will end up with a string.

Pandas way of solving this

The pandas.read_csv() function has a keyword argument called parse_dates

Using this you can on the fly convert strings, floats or integers into datetimes using the default date_parser (dateutil.parser.parser)

headers = ['col1', 'col2', 'col3', 'col4']
dtypes = {'col1': 'str', 'col2': 'str', 'col3': 'str', 'col4': 'float'}
parse_dates = ['col1', 'col2']
pd.read_csv(file, sep='\t', header=None, names=headers, dtype=dtypes, parse_dates=parse_dates)

This will cause pandas to read col1 and col2 as strings, which they most likely are ("2016-05-05" etc.) and after having read the string, the date_parser for each column will act upon that string and give back whatever that function returns.

Defining your own date parsing function:

The pandas.read_csv() function also has a keyword argument called date_parser

Setting this to a lambda function will make that particular function be used for the parsing of the dates.

GOTCHA WARNING

You have to give it the function, not the execution of the function, thus this is Correct

date_parser = pd.datetools.to_datetime

This is incorrect:

date_parser = pd.datetools.to_datetime()

Pandas 0.22 Update

pd.datetools.to_datetime has been relocated to date_parser = pd.to_datetime

If you are attempting to initialize a directory with an existing GitHub repository, you should ensure you are committing changes.

Try creating a file:

touch initial
git add initial
git commit -m "initial commit"
git push -u origin master

That will place a file named initial that you can delete later.

Hope this answer helps! Goodluck!

Cast the dtype of the col to str and you can perform vectorised slicing calling str:

In [29]:
df['new_col'] = df['First'].astype(str).str[0]
df

Out[29]:
   First  Second new_col
0    123     234       1
1     22    4353       2
2     32     355       3
3    453     453       4
4     45     345       4
5    453     453       4
6     56      56       5

if you need to you can cast the dtype back again calling astype(int) on the column

import jxl.Sheet;
import jxl.Workbook;
import jxl.read.biff.BiffException;

String FilePath = "/home/lahiru/Desktop/Sample.xls";
FileInputStream fs = new FileInputStream(FilePath);
Workbook wb = Workbook.getWorkbook(fs);

String <variable> = sh.getCell("A2").getContents();

In WebApi 2 you can add this to global.asax

protected void Application_PostAuthorizeRequest() 
{
    System.Web.HttpContext.Current.SetSessionStateBehavior(System.Web.SessionState.SessionStateBehavior.Required);
}

Then you could access the session through:

HttpContext.Current.Session

To my knowledge, you can't mock constructors with mockito, only methods. But according to the wiki on the Mockito google code page there is a way to mock the constructor behavior by creating a method in your class which return a new instance of that class. then you can mock out that method. Below is an excerpt directly from the Mockito wiki:

Pattern 1 - using one-line methods for object creation

To use pattern 1 (testing a class called MyClass), you would replace a call like

   Foo foo = new Foo( a, b, c );

with

   Foo foo = makeFoo( a, b, c );

and write a one-line method

   Foo makeFoo( A a, B b, C c ) { 
        return new Foo( a, b, c );
   }

It's important that you don't include any logic in the method; just the one line that creates the object. The reason for this is that the method itself is never going to be unit tested.

When you come to test the class, the object that you test will actually be a Mockito spy, with this method overridden, to return a mock. What you're testing is therefore not the class itself, but a very slightly modified version of it.

Your test class might contain members like

  @Mock private Foo mockFoo;
  private MyClass toTest = spy(new MyClass());

Lastly, inside your test method you mock out the call to makeFoo with a line like

  doReturn( mockFoo )
      .when( toTest )
      .makeFoo( any( A.class ), any( B.class ), any( C.class ));

You can use matchers that are more specific than any() if you want to check the arguments that are passed to the constructor.

If you're just wanting to return a mocked object of your class I think this should work for you. In any case you can read more about mocking object creation here:

http://code.google.com/p/mockito/wiki/MockingObjectCreation

In C, the order that you define things often matters. Either move the definition of outchar to the top, or provide a prototype at the top, like this:

#include <stdio.h> #include <stdlib.h>  void outchar(char ch);  int main() {     outchar('A');     outchar('B');     outchar('C');     return 0; }  void outchar(char ch) {     printf("%c", ch); } 

Also, you should be specifying the return type of every function. I added that for you.

Angular has an orderBy filter that can be used like this:

<select ng-model="selected" ng-options="f.name for f in friends | orderBy:'name'"></select>

See this fiddle for an example.

It's worth noting that if track by is being used it needs to appear after the orderBy filter, like this:

<select ng-model="selected" ng-options="f.name for f in friends | orderBy:'name' track by f.id"></select>

quoting @user2993582's answer

export PATH=$PATH:$ANDROID_HOME/bin

The 'bin' part has changed and it should be

export PATH=$PATH:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools

you can try this,it will work for you
