I had the same problem and only this solution worked for me (it runs a function after a complete DOM has been loaded). I use this for scroll to anchor after page has been loaded:

angular.element(window.document.body).ready(function () {

                        // Your function that runs after all DOM is loaded

                    });

The easiest (and standard) way to install Android SDK under OS X is to use brew.

brew install android-sdk

If you do not have homebrew, here's how to get it.

This will install Android SDK into /usr/local/Cellar/android-sdk/ and, at this moment, this is the best location to install it.

This is how I would go about it.

$posts = $this->post->orderBy('id', 'DESC')->get();

IE 8 doesn't have indexOf function, so I used jQuery inArray instead.

$('input').datepicker({
    beforeShowDay: function(date){
        var string = jQuery.datepicker.formatDate('yy-mm-dd', date);
        return [$.inArray(string, array) == -1];
    }
});

You can use a regular expression for that pretty easily…

Allowing spaces around the word (but not keeping them):

str.match(/< ?([^>]+) ?>\Z/)[1]

Or without the spaces allowed:

str.match(/<([^>]+)>\Z/)[1]

i have a solution for dynamically created variable value and combined all value in a variable.

if($_SERVER['REQUEST_METHOD']=='POST'){
    $r=0;
    for($i=1; $i<=4; $i++){
        $a = $_POST['a'.$i];
        $r .= $a;
    }
    echo $r;
}

there is one difference in behavior between [] and list() as example below shows. we need to use list() if we want to have the list of numbers returned, otherwise we get a map object! No sure how to explain it though.

sth = [(1,2), (3,4),(5,6)]
sth2 = map(lambda x: x[1], sth) 
print(sth2) # print returns object <map object at 0x000001AB34C1D9B0>

sth2 = [map(lambda x: x[1], sth)]
print(sth2) # print returns object <map object at 0x000001AB34C1D9B0>
type(sth2) # list 
type(sth2[0]) # map

sth2 = list(map(lambda x: x[1], sth))
print(sth2) #[2, 4, 6]
type(sth2) # list
type(sth2[0]) # int

Remove duplicates (Keeping First)

idx = np.unique( df.index.values, return_index = True )[1]
df = df.iloc[idx]

Remove duplicates (Keeping Last)

df = df[::-1]
df = df.iloc[ np.unique( df.index.values, return_index = True )[1] ]

Tests: 10k loops using OP's data

numpy method - 3.03 seconds
df.loc[~df.index.duplicated(keep='first')] - 4.43 seconds
df.groupby(df.index).first() - 21 seconds
reset_index() method - 29 seconds

The shortest implementation for capitalizing words within a string is the following using ES6's arrow functions:

'your string'.replace(/\b\w/g, l => l.toUpperCase())
// => 'Your String'

ES5 compatible implementation:

'your string'.replace(/\b\w/g, function(l){ return l.toUpperCase() })
// => 'Your String'

The regex basically matches the first letter of each word within the given string and transforms only that letter to uppercase:

• \b matches a word boundary (the beginning or ending of word);
• \w matches the following meta-character [a-zA-Z0-9].

For non-ASCII characters refer to this solution instead

'ÿöur striñg'.replace(/(^|\s)\S/g, l => l.toUpperCase())

This regex matches the first letter and every non-whitespace letter preceded by whitespace within the given string and transforms only that letter to uppercase:

• \s matches a whitespace character
• \S matches a non-whitespace character
• (x|y) matches any of the specified alternatives

A non-capturing group could have been used here as follows /(?:^|\s)\S/g though the g flag within our regex wont capture sub-groups by design anyway.

Cheers!

There would be multiple ways to find an element (in your case the third Google Search result).

One of the ways would be using Xpath

#For the 3rd Link
driver.findElement(By.xpath(".//*[@id='rso']/li[3]/div/h3/a")).click();
#For the 1st Link
driver.findElement(By.xpath(".//*[@id='rso']/li[2]/div/h3/a")).click();
#For the 2nd Link
driver.findElement(By.xpath(".//*[@id='rso']/li[1]/div/h3/a")).click();

The other options are

By.ByClassName 
By.ByCssSelector 
By.ById
By.ByLinkText
By.ByName
By.ByPartialLinkText 
By.ByTagName 

To better understand each one of them, you should try learning Selenium on something simpler than the Google Search Result page.

Example - http://www.google.com/intl/gu/contact/

To Interact with the Text input field with the placeholder "How can we help? Ask here." You could do it this way -

# By.ByClassName 
driver.findElement(By.ClassName("searchbox")).sendKeys("Hey!");
# By.ByCssSelector 
driver.findElement(By.CssSelector(".searchbox")).sendKeys("Hey!");
# By.ById
driver.findElement(By.Id("query")).sendKeys("Hey!");
# By.ByName
driver.findElement(By.Name("query")).sendKeys("Hey!");
# By.ByXpath
driver.findElement(By.xpath(".//*[@id='query']")).sendKeys("Hey!");

This has been the cleanest way to do it for me:-

ssh -n -f user@host "sh -c 'cd /whereever; nohup ./whatever > /dev/null 2>&1 &'"

The only thing running after this is the actual command on the remote machine

You are not specifying a language or framework, but the following header is used for file downloads:

"Content-Disposition: attachment; filename=abc.csv"

The ultimate solution to this error:

SOLUTION 1

Step 1 Go to File -> Invalidate Caches/Restart.

Step 2 Close the project.

Step 3 Go to project folder and delete .idea folder.

Step 4 Delete YourProjectName.iml in project folder.

step 5 You will see a folder below graddle folder, Delete YourProjectName folder (it contains another YourProjectName.iml file).

Step 6 Open Android studio -> open existing project, and then select your project.

**

SOLUTION 2

**

Step 1: Open the Corrupted Project (The one showing error).

Step 2: Open system.gradle file.

step 3: add this line of code include ':app'.

Step 4: click on the sync, to sync the gradle file.

Your sklearn version is too low, model_selection is imported by 0.18.1, so please update the sklearn version.

ax.set_title() should set the titles for separate subplots:

import matplotlib.pyplot as plt

if __name__ == "__main__":
    data = [1, 2, 3, 4, 5]

    fig = plt.figure()
    fig.suptitle("Title for whole figure", fontsize=16)
    ax = plt.subplot("211")
    ax.set_title("Title for first plot")
    ax.plot(data)

    ax = plt.subplot("212")
    ax.set_title("Title for second plot")
    ax.plot(data)

    plt.show()

Can you check if this code works for you? Maybe something overwrites them later?

You can use generic code inspection via instanceof:

var e = document.getElementById('#my-element');
if (e instanceof HTMLInputElement) {}         // <input>
elseif (e instanceof HTMLSelectElement) {}    // <select>
elseif (e instanceof HTMLTextAreaElement) {}  // <textarea>
elseif (  ... ) {}                            // any interface

Look here for a complete list of interfaces.

Only had to do the following to pick up @types in a Lerna Mono-repo where several node_modules exist.

npm install -D @types/jasmine

Then in each tsconfig.file of each module or app

"typeRoots": [
  "node_modules/@types",
  "../../node_modules/@types" <-- I added this line
],

When you use --user option with pip, the package gets installed in user's folder instead of global folder and you won't need to run pip command with admin privileges.

The location of user's packages folder can be found using:

python -m site --user-site

This will print something like:

C:\Users\%USERNAME%\AppData\Roaming\Python\Python35\site-packages

When you don't use --user option with pip, the package gets installed in global folder given by:

python -c "import site; print(site.getsitepackages())"

This will print something like:

['C:\\Program Files\\Anaconda3', 'C:\\Program Files\\Anaconda3\\lib\\site-packages'

Note: Above printed values are for On Windows 10 with Anaconda 4.x installed with defaults.

Here's what's actually happening localhost means that you want to open htdocs. First it will search for any file named index.php or index.html. If one of those exist it will open the file. If neither of those exist then it will open all folder/file inside htdocs directory which is what you want.

So, the simplest solution is to rename index.php or index.html to index2.php etc.

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

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

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

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

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

A linear search works by looking at each element in a list of data until it either finds the target or reaches the end. This results in O(n) performance on a given list. A binary search comes with the prerequisite that the data must be sorted. We can leverage this information to decrease the number of items we need to look at to find our target. We know that if we look at a random item in the data (let's say the middle item) and that item is greater than our target, then all items to the right of that item will also be greater than our target. This means that we only need to look at the left part of the data. Basically, each time we search for the target and miss, we can eliminate half of the remaining items. This gives us a nice O(log n) time complexity.

Just remember that sorting data, even with the most efficient algorithm, will always be slower than a linear search (the fastest sorting algorithms are O(n * log n)). So you should never sort data just to perform a single binary search later on. But if you will be performing many searches (say at least O(log n) searches), it may be worthwhile to sort the data so that you can perform binary searches. You might also consider other data structures such as a hash table in such situations.

Memcached is a newer API, it also provides memcached as a session provider which could be great if you have a farm of server.

After the version is still really low 0.2 but I have used both and I didn't encounter major problem, so I would go to memcached since it's new.

If you'd like to persisist cookies and session data, you'd best do it like this:

import requests

proxies = {
    'http': 'http://user:[email protected]:3128',
    'https': 'https://user:[email protected]:3128',
}

# Create the session and set the proxies.
s = requests.Session()
s.proxies = proxies

# Make the HTTP request through the session.
r = s.get('http://www.showmemyip.com/')

Here is the method I use:

double a=3.545555555; // just assigning your decimal to a variable
a=a*100;              // this sets a to 354.555555
a=Math.floor(a);      // this sets a to 354
a=a/100;              // this sets a to 3.54 and thus removing all your 5's

This can also be done:

a=Math.floor(a*100) / 100;

Just use this

$i=0;
foreach ($object as $key =>$value)
{
$i++;
}

the variable $i is number of keys.

Assuming that both of those are Strings (otherwise they'd already be valid Dates), here's one way:

package cruft;

import java.text.DateFormat;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;

public class DateValidator
{
    private static final DateFormat DEFAULT_FORMATTER;

    static
    {
        DEFAULT_FORMATTER = new SimpleDateFormat("dd-MM-yyyy");
        DEFAULT_FORMATTER.setLenient(false);
    }

    public static void main(String[] args)
    {
        for (String dateString : args)
        {
            try
            {
                System.out.println("arg: " + dateString + " date: " + convertDateString(dateString));
            }
            catch (ParseException e)
            {
                System.out.println("could not parse " + dateString);
            }
        }
    }

    public static Date convertDateString(String dateString) throws ParseException
    {
        return DEFAULT_FORMATTER.parse(dateString);
    }
}

Here's the output I get:

java cruft.DateValidator 32-11-2010 31-02-2010 04-01-2011
could not parse 32-11-2010
could not parse 31-02-2010

As you can see, it does handle both of your cases nicely.

In my case reload() doesn't work because the asp.net controls behavior. So, to solve this issue I've used this approach, despite seems a work around.

self.clear = function () {
    //location.reload(true); Doesn't work to IE neither Firefox;
    //also, hash tags must be removed or no postback will occur.
    window.location.href = window.location.href.replace(/#.*$/, '');
};

Had the same problem recently.

I discovered that simply defining DataType as Date in the model works as well (using Code First approach)

[DataType(DataType.Date)]
public DateTime Added { get; set; }

I tried the suggestion offered by @shasi kanth, but it didn't work out. I read the documentation and there are few changes made. So I managed to send mail via Gmail using this code, where vendor/autoload.php is got by composer with composer require "swiftmailer/swiftmailer:^6.0":

<?php
     require_once 'vendor/autoload.php';
     $transport = (new Swift_SmtpTransport('smtp.gmail.com', 465, 'ssl'))->setUsername ('SendingMail')->setPassword ('Password');

     $mailer = new Swift_Mailer($transport);

     $message = (new Swift_Message('test'))
      ->setFrom(['Sending mail'])
      ->setTo(['Recipient mail'])
      ->setBody('Message')
  ;

     $result = $mailer->send($message);
    ?>

Add this to webpack.config.js:

devServer: {
    historyApiFallback: true
}

make sure the submit button is not of type "submit", make it a button. Then use the onclick event to trigger some javascript. There you can do whatever you want before you actually post your data.

In each parent LinearLayout for which you want dividers between components, add android:divider="?android:dividerHorizontal" or android:divider="?android:dividerVertical.

Choose appropriate between them as per orientation of your LinearLayout.

Till I know, this resource style is added from Android 4.3.

I know this is an old post and you marked the question as answered. I was looking for the same thing recently and I found the histedit extension very useful. The process is explained here:

pushing a value (not necessarily stored in a register) means writing it to the stack.

popping means restoring whatever is on top of the stack into a register. Those are basic instructions:

push 0xdeadbeef      ; push a value to the stack
pop eax              ; eax is now 0xdeadbeef

; swap contents of registers
push eax
mov eax, ebx
pop ebx

Have you tried just using the mysql command line client directly?

mysql -u username -p -h hostname databasename < dump.sql

If you can't do that, there are any number of utilities you can find by Googling that help you import a large dump into MySQL, like BigDump

There is no Javascript API to send ping frames or receive pong frames. This is either supported by your browser, or not. There is also no API to enable, configure or detect whether the browser supports and is using ping/pong frames. There was discussion about creating a Javascript ping/pong API for this. There is a possibility that pings may be configurable/detectable in the future, but it is unlikely that Javascript will be able to directly send and receive ping/pong frames.

However, if you control both the client and server code, then you can easily add ping/pong support at a higher level. You will need some sort of message type header/metadata in your message if you don't have that already, but that's pretty simple. Unless you are planning on sending pings hundreds of times per second or have thousands of simultaneous clients, the overhead is going to be pretty minimal to do it yourself.

You could pass a Class<T> in.

private void foo(Class<?> cls) {
    if (cls == String.class) { ... }
    else if (cls == int.class) { ... }
}

private void bar() {
    foo(String.class);
}

Update: the OOP way depends on the functional requirement. Best bet would be an interface defining foo() and two concrete implementations implementing foo() and then just call foo() on the implementation you've at hand. Another way may be a Map<Class<?>, Action> which you could call by actions.get(cls). This is easily to be combined with an interface and concrete implementations: actions.get(cls).foo().

In the thread dump you can find the Line Number as below.

Annotations come from the support's library which are packaged in android.support.annotation.

As another option you can use @NonNull annotation which denotes that a parameter, field or method return value can never be null.
It is imported from import android.support.annotation.NonNull;

This should do it:

l[4] = -1

Log4j2 can be configured to refresh its configuration by scanning the log4j2.xml file (or equivalent) at given intervals. Just add the "monitorInterval" parameter to your configuration tag. See line 2 of the sample log4j2.xml file, which tells log4j to to re-scan its configuration if more than 5 seconds have passed since the last log event.

<?xml version="1.0" encoding="UTF-8" ?>
<Configuration status="warn" monitorInterval="5" name="tryItApp" packages="">

There are extra steps to make this work if you are deploying to a tomcat instance, inside an IDE, or when using spring boot. That seems somewhat out of scope here and probably merits a separate question.

Solution: Step1: Have to remove “lock” file which present under “.svn” hidden file. Step2: In case if there is no “lock” file then you would see “we.db” you have to open this database and need to delete content alone from the following tables – lock – wc_lock Step3: Clean your project Step4: Try to commit now. Step5: Done.

You could just do something like this:

SELECT *
FROM foo
WHERE (@param = 0 AND MyColumn IS NULL)
OR (@param = 1 AND MyColumn IS NOT NULL)
OR (@param = 2)

Something like that.

I think this table is short and usefull:

Supplier       ()    -> x
Consumer       x     -> ()
Callable       ()    -> x throws ex
Runnable       ()    -> ()
Function       x     -> y
BiFunction     x,y   -> z
Predicate      x     -> boolean
UnaryOperator  x1    -> x2
BinaryOperator x1,x2 -> x3

As said on the other answers, the appropriate option for this problem is a Runnable

This is a very late addition to this thread but I've been working on an image view that supports zoom and pan and has a couple of features I haven't found elsewhere. This started out as a way of displaying very large images without causing OutOfMemoryErrors, by subsampling the image when zoomed out and loading higher resolution tiles when zoomed in. It now supports use in a ViewPager, rotation manually or using EXIF information (90° stops), override of selected touch events using OnClickListener or your own GestureDetector or OnTouchListener, subclassing to add overlays, pan while zooming, and fling momentum.

It's not intended as a general use replacement for ImageView so doesn't extend it, and doesn't support display of images from resources, only assets and external files. It requires SDK 10.

Source is on GitHub, and there's a sample that illustrates use in a ViewPager.

I was having this issue building a SQL Server project on a CI/CD pipeline. In fact, I was having it locally as well, and I did not manage to solve it.

What worked for me was using an MSBuild SDK, capable of producing a SQL Server Data-Tier Application package (.dacpac) from a set of SQL scripts, which implies creating a new project. But I wanted to keep the SQL Server project, so that I could link it to the live database through SQL Server Object Explorer on Visual Studio. I took the following steps to have this up and running:

1. Kept my SQL Server project with the .sql database scripts.
2. Created a .NET Standard 2.0 class library project, making sure that the target framework was .NET Standard 2.0, as per the guidelines in the above link.

3. Set the contents of the .csproj as follows:

   <?xml version="1.0" encoding="utf-8"?>
   <Project Sdk="MSBuild.Sdk.SqlProj/1.0.0">
     <PropertyGroup>
       <SqlServerVersion>Sql140</SqlServerVersion>
       <TargetFramework>netstandard2.0</TargetFramework>
     </PropertyGroup>
   </Project>
   

4. I have chosen Sql140 as the SQL Server version because I am using SQL Server 2019. Check this answer to find out the mapping to the version you are using.

5. Ignore the SQL Server project on build, so that it stops breaking locally (it does build on Visual Studio, but it fails on VS Code).

6. Now we just have to make sure the .sql files are inside the SDK project when it is built. I achieved that with a simple powershell routine on the CI/CD pipeline that would copy the files from the SQL Server project to the SDK project:

Copy-Item -Path "Path.To.The.Database.Project\dbo\Tables\*" -Destination (New-item -Name "dbo\Tables" -Type Directory -Path "Path.To.The.DatabaseSDK.Project\")

PS: The files have to be physically in the SDK project, either in the root or on some folder, so links to the .sdk files in the SQL Server project won't work. In theory, it should be possible to copy these files with a pre-build condition, but for some obscure reason, this was not working for me. I tried also to have the .sql files on the SDK project and link them to the SQL Server project, but that would easily break the link with the SQL Server Object Explorer, so I decided to drop this as well.

In ST2 there's a package you can install called Default FileType which does just that.

More info here.

1. add in proxy.conf.json, all request to /api will be redirect to htt://targetIP:targetPort/api.

{
  "/api": {
    "target": "http://targetIP:targetPort",
    "secure": false,
    "pathRewrite": {"^/api" : targeturl/api},
    "changeOrigin": true,
    "logLevel": "debug"
  }
}

2. in package.json, make "start": "ng serve --proxy-config proxy.conf.json"

3. in code let url = "/api/clnsIt/dev/78"; this url will be translated to http://targetIP:targetPort/api/clnsIt/dev/78.

4. You can also force rewrite by filling the pathRewrite. This is the link for details cmd/NPM console will log something like "Rewriting path from "/api/..." to "http://targeturl:targetPort/api/..", while browser console will log "http://loclahost/api"

This thread has a good discussion and a useful solution:

function pause( iMilliseconds )
{
    var sDialogScript = 'window.setTimeout( function () { window.close(); }, ' + iMilliseconds + ');';
    window.showModalDialog('javascript:document.writeln ("<script>' + sDialogScript + '<' + '/script>")');
}

Unfortunately it appears that this doesn't work in some versions of IE, but the thread has many other worthy proposals if that proves to be a problem for you.

It used to be installed with the .NET framework. MsBuild v12.0 (2013) is now bundled as a stand-alone utility and has it's own installer.

http://www.microsoft.com/en-us/download/confirmation.aspx?id=40760

To reference the location of MsBuild.exe from within an MsBuild script, use the default $(MsBuildToolsPath) property.

You can do so by these ways.

Add watchpoint and while debugging you can see variable in debugger window perspective under variable tab. OR Add System.out.println("variable = " + variable); and see in console.

We can also use the String constructor. According to this benchmark it's the fastest way to convert a Number to String in Firefox 58 even though it's slower than " + num in the popular browser Google Chrome.

In order to use local gem repository in a Rails project, follow the steps below:

1. Check if your gem folder is a git repository (the command is executed in the gem folder)

   git rev-parse --is-inside-work-tree
   

2. Getting repository path (the command is executed in the gem folder)

   git rev-parse --show-toplevel
   

3. Setting up a local override for the rails application

   bundle config local.GEM_NAME /path/to/local/git/repository
   

   where GEM_NAME is the name of your gem and /path/to/local/git/repository is the output of the command in point 2

4. In your application Gemfile add the following line:

   gem 'GEM_NAME', :github => 'GEM_NAME/GEM_NAME', :branch => 'master'
   

5. Running bundle install should give something like this:

   Using GEM_NAME (0.0.1) from git://github.com/GEM_NAME/GEM_NAME.git (at /path/to/local/git/repository) 
   

   where GEM_NAME is the name of your gem and /path/to/local/git/repository from point 2

6. Finally, run bundle list, not gem list and you should see something like this:

   GEM_NAME (0.0.1 5a68b88)
   

   where GEM_NAME is the name of your gem

A few important cases I am observing using:

Rails 4.0.2  
ruby 2.0.0p247 (2013-06-27 revision 41674) [x86_64-linux] 
Ubuntu 13.10  
RubyMine 6.0.3

• It seems RubyMine is not showing local gems as an external library. More information about the bug can be found here and here
• When I am changing something in the local gem, in order to be loaded in the rails application I should stop/start the rails server

• If I am changing the version of the gem, stopping/starting the Rails server gives me an error. In order to fix it, I am specifying the gem version in the rails application Gemfile like this:

  gem 'GEM_NAME', '0.0.2', :github => 'GEM_NAME/GEM_NAME', :branch => 'master'
  

DTO is an abbreviation for Data Transfer Object, so it is used to transfer the data between classes and modules of your application.

• DTO should only contain private fields for your data, getters, setters, and constructors.
• DTO is not recommended to add business logic methods to such classes, but it is OK to add some util methods.

DAO is an abbreviation for Data Access Object, so it should encapsulate the logic for retrieving, saving and updating data in your data storage (a database, a file-system, whatever).

Here is an example of how the DAO and DTO interfaces would look like:

interface PersonDTO {
    String getName();
    void setName(String name);
    //.....
}

interface PersonDAO {
    PersonDTO findById(long id);
    void save(PersonDTO person);
    //.....
}

The MVC is a wider pattern. The DTO/DAO would be your model in the MVC pattern.
It tells you how to organize the whole application, not just the part responsible for data retrieval.

As for the second question, if you have a small application it is completely OK, however, if you want to follow the MVC pattern it would be better to have a separate controller, which would contain the business logic for your frame in a separate class and dispatch messages to this controller from the event handlers.
This would separate your business logic from the view.

XOR is a binary operation, it stands for "exclusive or", that is to say the resulting bit evaluates to one if only exactly one of the bits is set.

This is its function table:

a | b | a ^ b
--|---|------
0 | 0 | 0
0 | 1 | 1
1 | 0 | 1
1 | 1 | 0

This operation is performed between every two corresponding bits of a number.

Example: 7 ^ 10
In binary: 0111 ^ 1010

  0111
^ 1010
======
  1101 = 13

Properties: The operation is commutative, associative and self-inverse.

It is also the same as addition modulo 2.

To change dir

foo: 
    $(MAKE) -C mydir

multi:
    $(MAKE) -C / -C my-custom-dir   ## Equivalent to /my-custom-dir

I still think using Join is simpler. Record the expected completion time (as Now+timeout), then, in a loop, do

if(!thread.Join(End-now))
    throw new NotFinishedInTime();

If your npm version is lower than version 5 then install the higher version for getting the automatic generation of package-lock.json.

Example: Upgrade your current npm to version 6.14.0

npm i -g [email protected]

You could view the latest npm version list by

npm view npm versions

i faced the same issue few days earlier for my IONIC 4 Project. when i uploaded my IPA, i got this warnings from App Store Connect.

I fixed the "Missing Purpose String in info.plist" issue, by the following steps. hope it will also work for you.

1. Goto your "info.plist" file.

2. Find this key, called Privacy - Photo Library Usage Description. if it's not present there, add a new one and it's value, like below image.

Thanks.

This is how you can create a beautiful button with a bezel and rounded edges:

loginButton = UIButton(frame: CGRectMake(self.view.bounds.origin.x + (self.view.bounds.width * 0.325), self.view.bounds.origin.y + (self.view.bounds.height * 0.8), self.view.bounds.origin.x + (self.view.bounds.width * 0.35), self.view.bounds.origin.y + (self.view.bounds.height * 0.05)))
loginButton.layer.cornerRadius = 18.0
loginButton.layer.borderWidth = 2.0
loginButton.backgroundColor = UIColor.whiteColor()
loginButton.layer.borderColor = UIColor.whiteColor().CGColor
loginButton.setTitle("Login", forState: UIControlState.Normal)
loginButton.setTitleColor(UIColor(red: 24.0/100, green: 116.0/255, blue: 205.0/205, alpha: 1.0), forState: UIControlState.Normal)

5== will indent five lines from the current cursor position.

So you can type any number before ==. It will indent the number of lines. This is in command mode.

gg=G will indent the whole file from top to bottom.

One way to do it will be to move all the php code above the HTML, copy the result to a variable and then add the result in the <input> tag.
Try this -

<?php
//Adding the php to the top.
if(isset($_POST['submit']))
{
    $value1=$_POST['value1'];
    $value2=$_POST['value2'];
    $sign=$_POST['sign'];
    ...
        //Adding to $result variable
    if($sign=='-') {
      $result = $value1-$value2;
    }
    //Rest of your code...
}
?>
<html>
<!--Rest of your tags...-->
Result:<br><input type"text" name="result" value = "<?php echo (isset($result))?$result:'';?>">

A complete solution for anyone that might need it, I've used this with good results so far

JS:

$(".btn-popover-container").each(function() {
    var btn = $(this).children(".popover-btn");
    var titleContainer = $(this).children(".btn-popover-title");
    var contentContainer = $(this).children(".btn-popover-content");

    var title = $(titleContainer).html();
    var content = $(contentContainer).html();

    $(btn).popover({
        html: true,
        title: title,
        content: content,
        placement: 'right'
    });
});

HTML:

<div class="btn-popover-container">
    <button type="button" class="btn btn-link popover-btn">Button Name</button>
    <div class="btn-popover-title">
        Popover Title
    </div>
    <div class="btn-popover-content">
        <form>
          Or Other content..
        </form>
    </div>
</div>

CSS:

.btn-popover-container {
    display: inline-block;
}


.btn-popover-container .btn-popover-title, .btn-popover-container .btn-popover-content {
    display: none;
}

The reason for the error is that the nextInt only pulls the integer, not the newline. If you add a in.nextLine() before your for loop, it will eat the empty new line and allow you to enter 3 names.

int nnames;
String names[];

System.out.print("How many names are you going to save: ");
Scanner in = new Scanner(System.in);
nnames = in.nextInt();

names = new String[nnames];
in.nextLine();
for (int i = 0; i < names.length; i++){
        System.out.print("Type a name: ");
        names[i] = in.nextLine();
}

or just read the line and parse the value as an Integer.

int nnames;
String names[];

System.out.print("How many names are you going to save: ");
Scanner in = new Scanner(System.in);
nnames = Integer.parseInt(in.nextLine().trim());

names = new String[nnames];
for (int i = 0; i < names.length; i++){
        System.out.print("Type a name: ");
        names[i] = in.nextLine();
}

It is indeed possible to change a div elements' width in jQuery:

$("#div").css("width", "300px");

However, what you're describing can be better and more effectively achieved in CSS by setting a width as a percentage:

#div {
    width: 75%;
    /* You can also specify min/max widths */
    min-width: 300px;
    max-width: 960px;
}

This div will then always be 75% the width of the screen, unless the screen width means the div will be smaller than 300px, or bigger than 960px.

Wherever you want vertically center style means you can try display:table-cell and vertical-align:middle.

Example:

#box_x000D_
{_x000D_
  display: table-cell;_x000D_
  vertical-align: middle;_x000D_
  height: 90px;_x000D_
  width: 270px;_x000D_
  background: #000;_x000D_
  font-size: 48px;_x000D_
  font-style: oblique;_x000D_
  color: #FFF;_x000D_
  text-align: center;_x000D_
  margin-top: 20px;_x000D_
  margin-left: 5px;_x000D_
}

<div Id="box">_x000D_
  Lorem ipsum dolor sit amet, consectetur adipiscing elit._x000D_
</div>

Am adding this answer for the purpose of those who google about this..

There was an episode of DevBytes (ListView Cell Dragging and Rearranging) recently which explains how to do this

You can find it here also the sample code is available here.

What this code basically does is that it creates a dynamic listview by the extension of listview that supports cell dragging and swapping. So that you can use the DynamicListView instead of your basic ListView and that's it you have implemented a ListView with Drag and Drop.

You simply misspelled $stateParam, it should be $stateParams (with an s). That's why you get undefined ;)

$timestamp = strtotime($row['DATETIMEAPP']);

gives you timestamp, which then you can use date to format:

$date = date('d-m-Y', $timestamp);
$time = date('Gi.s', $timestamp);

Alternatively

list($date, $time) = explode('|', date('d-m-Y|Gi.s', $timestamp));

Simply add Templates URL:

<a href="{% url 'service_data' d.id %}">
 ...XYZ
</a>

You seem to have the quote marks (") embedded in your string at the start and the end. These are not needed and are illegal characters in a path. How are you initializing the string with the path?

This can be seen from the debugger visualizer, as the string starts with "\" and ends with \"", it shows that the quotes are part of the string, when they shouldn't be.

You can do two thing - a regular escaped string (using \) or a verbatim string literal (that starts with a @):

  string str = "C:\\Program Files (x86)\\test software\\myapp\\demo.exe";

Or:

  string verbatim = @"C:\Program Files (x86)\test software\myapp\demo.exe";

datetime is a module which contains a type that is also called datetime. You appear to want to use both, but you're trying to use the same name to refer to both. The type and the module are two different things and you can't refer to both of them with the name datetime in your program.

If you need to use anything from the module besides the datetime type (as you apparently do), then you need to import the module with import datetime. You can then refer to the "date" type as datetime.date and the datetime type as datetime.datetime.

You could also do this:

from datetime import datetime, date
today_date = date.today()
date_time = datetime.strp(date_time_string, '%Y-%m-%d %H:%M')

Here you import only the names you need (the datetime and date types) and import them directly so you don't need to refer to the module itself at all.

Ultimately you have to decide what names from the module you need to use, and how best to use them. If you are only using one or two things from the module (e.g., just the date and datetime types), it may be okay to import those names directly. If you're using many things, it's probably better to import the module and access the things inside it using dot syntax, to avoid cluttering your global namespace with date-specific names.

Note also that, if you do import the module name itself, you can shorten the name to ease typing:

import datetime as dt
today_date = dt.date.today()
date_time = dt.datetime.strp(date_time_string, '%Y-%m-%d %H:%M')

I had a similar problem. I would suggest using the PIL library in python as it draws the text in any given font, compared to limited fonts in OpenCV. With PIL you can choose any font installed on your system.

from PIL import ImageFont, ImageDraw, Image
import numpy as np
import cv2

image = cv2.imread("lena.png")

# Convert to PIL Image
cv2_im_rgb = cv2.cvtColor(image, cv2.COLOR_BGR2RGB)
pil_im = Image.fromarray(cv2_im_rgb)

draw = ImageDraw.Draw(pil_im)

# Choose a font
font = ImageFont.truetype("Roboto-Regular.ttf", 50)

# Draw the text
draw.text((0, 0), "Your Text Here", font=font)

# Save the image
cv2_im_processed = cv2.cvtColor(np.array(pil_im), cv2.COLOR_RGB2BGR)
cv2.imwrite("result.png", cv2_im_processed)

result.png

Try this:

System.Net.ServicePointManager.SecurityProtocol = System.Net.SecurityProtocolType.Tls12;

Notice that you have to work at least with 4.5 .NET framework

I'm using the mollwe function, although I added 2 improvements:

a) Avoid the dropdown closing if the link clicked is collapsed (including other links)

b) Hide the dropdown too, if you are clicking the visible web content.

jQuery.fn.exists = function() {
                  return this.length > 0;
              }

    $(function() {
                var navMain = $(".navbar-collapse");
                navMain.on("click", "a", null, function() {
                    if ($(this).attr("href") !== "#") {
                        navMain.collapse('hide');
                    }
                });

                $("#content").bind("click", function() {
                     if ($(".navbar-collapse.navbar-ex1-collapse.in").exists()) {
                        navMain.collapse('hide');
                    }
                });

            });

// wrap it in jQuery, now it's a collection
var $elements = $(someHTML);

// append to the DOM
$("#myDiv").append($elements);

// do stuff, using the initial reference
$elements.effects("highlight", {}, 2000);

The humble for command has accumulated some interesting capabilities over the years:

D:\> FOR /F "delims=" %i IN ('date /t') DO set today=%i
D:\> echo %today%
Sat 20/09/2008

Note that "delims=" overwrites the default space and tab delimiters so that the output of the date command gets gobbled all at once.

To capture multi-line output, it can still essentially be a one-liner (using the variable lf as the delimiter in the resulting variable):

REM NB:in a batch file, need to use %%i not %i
setlocal EnableDelayedExpansion
SET lf=-
FOR /F "delims=" %%i IN ('dir \ /b') DO if ("!out!"=="") (set out=%%i) else (set out=!out!%lf%%%i)
ECHO %out%

To capture a piped expression, use ^|:

FOR /F "delims=" %%i IN ('svn info . ^| findstr "Root:"') DO set "URL=%%i"

There are several ways I can think of to do this.

Use a callback:

 function FunctInit(someVarible){
      //init and fill screen
      AndroidCallGetResult();  // Enables Android button.
 }

 function getResult(){ // Called from Android button only after button is enabled
      //return some variables
 }

Use a Timeout (this would probably be my preference):

 var inited = false;
 function FunctInit(someVarible){
      //init and fill screen
      inited = true;
 }

 function getResult(){
      if (inited) {
           //return some variables
      } else {
           setTimeout(getResult, 250);
      }
 }

Wait for the initialization to occur:

 var inited = false;
 function FunctInit(someVarible){
      //init and fill screen
      inited = true;
 }

 function getResult(){
      var a = 1;
      do { a=1; }
      while(!inited);
      //return some variables
 }

I would suggest to check the ASCII values to extract numbers from a String Suppose you have an input String as myname12345 and if you want to just extract the numbers 12345 you can do so by first converting the String to Character Array then use the following pseudocode

    for(int i=0; i < CharacterArray.length; i++)
    {
        if( a[i] >=48 && a[i] <= 58)
            System.out.print(a[i]);
    }

once the numbers are extracted append them to an array

Hope this helps

In answer the question heading (found by a google search) and not the re-question To stop the line breaking when you have different heading tags e.g.

<h5 style="display:inline;"> What the... </h5><h1 style="display:inline;"> heck is going on? </h1>

Will give you:

What the...heck is going on?

and not

What the... 
heck is going on?

I needed to know this and came here, before I remembered the Environment class.

In case anyone else had this issue, just use this: Environment.CurrentDirectory.

Example:

Dim dataDirectory As String = String.Format("{0}\Data\", Environment.CurrentDirectory)

When run from Visual Studio in debug mode yeilds:

C:\Development\solution folder\application folder\bin\debug

This is the exact behaviour I needed, and its simple and straightforward enough.

In my case the function throwing error was async so I followed here:

await expectAsync(asyncFunction()).toBeRejected();
await expectAsync(asyncFunction()).toBeRejectedWithError(...);

From my understanding of the code provided above, it loads the file and does map operation and saves it back. There is no operation that requires shuffle. Also, there is no operation that requires data to be brought to the driver hence tuning anything related to shuffle or driver may have no impact. The driver does have issues when there are too many tasks but this was only till spark 2.0.2 version. There can be two things which are going wrong.

• There are only one or a few executors. Increase the number of executors so that they can be allocated to different slaves. If you are using yarn need to change num-executors config or if you are using spark standalone then need to tune num cores per executor and spark max cores conf. In standalone num executors = max cores / cores per executor .
• The number of partitions are very few or maybe only one. So if this is low even if we have multi-cores,multi executors it will not be of much help as parallelization is dependent on the number of partitions. So increase the partitions by doing imageBundleRDD.repartition(11)

Solution using just POST - no $_SESSION

page1.php

<form action="page2.php" method="post">
    <textarea name="textarea1" id="textarea1"></textarea><br />
    <input type="submit" value="submit" />
</form>

page2.php

<?php
    // this page outputs the contents of the textarea if posted
    $textarea1 = ""; // set var to avoid errors
    if(isset($_POST['textarea1'])){
        $textarea1 = $_POST['textarea1']
    }
?>
<textarea><?php echo $textarea1;?></textarea>

Solution using $_SESSION and POST

page1.php

<?php

    session_start(); // needs to be before anything else on page to use $_SESSION
    $textarea1 = "";
    if(isset($_POST['textarea1'])){
        $_SESSION['textarea1'] = $_POST['textarea1'];
    }

?>


<form action="page1.php" method="post">
    <textarea name="textarea1" id="textarea1"></textarea><br />
    <input type="submit" value="submit" />
</form>
<br /><br />
<a href="page2.php">Go to page2</a>

page2.php

<?php
    session_start(); // needs to be before anything else on page to use $_SESSION
    // this page outputs the textarea1 from the session IF it exists
    $textarea1 = ""; // set var to avoid errors
    if(isset($_SESSION['textarea1'])){
        $textarea1 = $_SESSION['textarea1']
    }
?>
<textarea><?php echo $textarea1;?></textarea>

WARNING!!! - This contains no validation!!!

The example code leads to a memory leak in Tomcat (after undeploying the webapp, the classloader still remains in memory) which will cause an outofmemory eventually. The way to solve it is to use the sqlite-jdbc-3.7.8.jar; it's a snapshot, so it doesn't appear for maven yet.

The bug has been fixed in the latest androidx version. And the famous workaround will cause crash now. so we need not it now.

Also check this answer from here: Cannot manually edit applicationhost.config

The answer is simple, if not that obvious: win2008 is 64bit, notepad++ is 32bit. When you navigate to Windows\System32\inetsrv\config using explorer you are using a 64bit program to find the file. When you open the file using using notepad++ you are trying to open it using a 32bit program. The confusion occurs because, rather than telling you that this is what you are doing, windows allows you to open the file but when you save it the file's path is transparently mapped to Windows\SysWOW64\inetsrv\Config.

So in practice what happens is you open applicationhost.config using notepad++, make a change, save the file; but rather than overwriting the original you are saving a 32bit copy of it in Windows\SysWOW64\inetsrv\Config, therefore you are not making changes to the version that is actually used by IIS. If you navigate to the Windows\SysWOW64\inetsrv\Config you will find the file you just saved.

How to get around this? Simple - use a 64bit text editor, such as the normal notepad that ships with windows.

An SQL JOIN clause is used to combine rows from two or more tables, based on a common field between them.

There are different types of joins available in SQL:

INNER JOIN: returns rows when there is a match in both tables.

LEFT JOIN: returns all rows from the left table, even if there are no matches in the right table.

RIGHT JOIN: returns all rows from the right table, even if there are no matches in the left table.

FULL JOIN: It combines the results of both left and right outer joins.

The joined table will contain all records from both the tables and fill in NULLs for missing matches on either side.

SELF JOIN: is used to join a table to itself as if the table were two tables, temporarily renaming at least one table in the SQL statement.

CARTESIAN JOIN: returns the Cartesian product of the sets of records from the two or more joined tables.

WE can take each first four joins in Details :

We have two tables with the following values.

TableA

id  firstName                  lastName
.......................................
1   arun                        prasanth                 
2   ann                         antony                   
3   sruthy                      abc                      
6   new                         abc                                           

TableB

id2 age Place
................
1   24  kerala
2   24  usa
3   25  ekm
5   24  chennai

....................................................................

INNER JOIN

Note :it gives the intersection of the two tables, i.e. rows they have common in TableA and TableB

Syntax

SELECT table1.column1, table2.column2...
  FROM table1
 INNER JOIN table2
    ON table1.common_field = table2.common_field;

Apply it in our sample table :

SELECT TableA.firstName,TableA.lastName,TableB.age,TableB.Place
  FROM TableA
 INNER JOIN TableB
    ON TableA.id = TableB.id2;

Result Will Be

firstName       lastName       age  Place
..............................................
arun            prasanth        24  kerala
ann             antony          24  usa
sruthy          abc             25  ekm

LEFT JOIN

Note : will give all selected rows in TableA, plus any common selected rows in TableB.

Syntax

SELECT table1.column1, table2.column2...
  FROM table1
  LEFT JOIN table2
    ON table1.common_field = table2.common_field;

Apply it in our sample table :

SELECT TableA.firstName,TableA.lastName,TableB.age,TableB.Place
  FROM TableA
  LEFT JOIN TableB
    ON TableA.id = TableB.id2;

Result

RIGHT JOIN

Note : will give all selected rows in TableB, plus any common selected rows in TableA.

Syntax

SELECT table1.column1, table2.column2...
  FROM table1
 RIGHT JOIN table2
    ON table1.common_field = table2.common_field;

Apply it in our sample table :

SELECT TableA.firstName,TableA.lastName,TableB.age,TableB.Place
  FROM TableA
 RIGHT JOIN TableB
    ON TableA.id = TableB.id2;

Result

firstName                   lastName                    age     Place

FULL JOIN

Note :It will return all selected values from both tables.

Syntax

SELECT table1.column1, table2.column2...
  FROM table1
  FULL JOIN table2
    ON table1.common_field = table2.common_field;

Apply it in our sample table :

SELECT TableA.firstName,TableA.lastName,TableB.age,TableB.Place

Interesting Fact

For INNER joins the order doesn't matter

For (LEFT, RIGHT or FULL) OUTER joins,the order matter

Better to go check this Link it will give you interesting details about join order

In addition to return false as Jason Cohen mentioned. You may have to also preventDefault

e.preventDefault();

We can also pass controller function as variable in the view page.

class My_controller extends CI_Controller {
    public function index() {
           $data['val']=3;
           $data['square']=function($val){
                               return $val*$val;
                                   };
    $this->load->view('my-view',$data);
}
}

In the view page

<p>Square of <?=$val?>
   <?php 
     echo $square($val); 
   ?>
</p>

The output is 9

You can add parameter columns or use dict with key which is converted to column name:

np.random.seed(123)
e = np.random.normal(size=10)  
dataframe=pd.DataFrame(e, columns=['a']) 
print (dataframe)
          a
0 -1.085631
1  0.997345
2  0.282978
3 -1.506295
4 -0.578600
5  1.651437
6 -2.426679
7 -0.428913
8  1.265936
9 -0.866740

e_dataframe=pd.DataFrame({'a':e}) 
print (e_dataframe)
          a
0 -1.085631
1  0.997345
2  0.282978
3 -1.506295
4 -0.578600
5  1.651437
6 -2.426679

8  1.265936
9 -0.866740

You should definitely extend you ArrayListAdapter and implement this in your getView() method. The second parameter (a View) should be inflated if it's value is null, take advantage of it and set it an onClickListener() just after inflating.

Suposing it's called your second getView()'s parameter is called convertView:

convertView.setOnClickListener(new View.OnClickListener() {
  public void onClick(final View v) {
    if (isSamsung) {
      final Intent intent = new Intent(this, SamsungInfo.class);
      startActivity(intent);
    }
    else if (...) {
      ...
    }
  }
}

If you want some info on how to extend ArrayListAdapter, I recommend this link.

[self score]; you don't need @sel for calling directly

You can escape the calc arguments in order to prevent them from being evaluated on compilation.

Using your example, you would simply surround the arguments, like this:

calc(~'100% - 10px')

Demo : http://jsfiddle.net/c5aq20b6/

I find that I use this in one of the following three ways:

Basic Escaping

Everything inside the calc arguments is defined as a string, and is totally static until it's evaluated by the client:

LESS Input

div {
    > span {
        width: calc(~'100% - 10px');
    }
}

CSS Output

div > span {
  width: calc(100% - 10px);
}

Interpolation of Variables

You can insert a LESS variable into the string:

LESS Input

div {
    > span {
        @pad: 10px;
        width: calc(~'100% - @{pad}');
    }
}

CSS Output

div > span {
  width: calc(100% - 10px);
}

Mixing Escaped and Compiled Values

You may want to escape a percentage value, but go ahead and evaluate something on compilation:

LESS Input

@btnWidth: 40px;
div {
    > span {
        @pad: 10px;
        width: calc(~'(100% - @{pad})' - (@btnWidth * 2));
    }
}

CSS Output

div > span {
  width: calc((100% - 10px) - 80px);
}

Old question, but I had this issue as well, so after assigning the Text property, calling Refresh() will update the text.

Label1.Text = "Du har nu lånat filmen:" + test;
Refresh();

Here's the node version:

uriencode() {
  node -p "encodeURIComponent('${1//\'/\\\'}')"
}

If an object's property may refer to some other object then you can test that for undefined before trying to use its properties:

if (thing && thing.foo)
   alert(thing.foo.bar);

I could update my answer to better reflect your situation if you show some actual code, but possibly something like this:

function someFunc(parameterName) {
   if (parameterName && parameterName.foo)
       alert(parameterName.foo.bar);
}

you can define the variable global , but when using this variable must to write in script block .

def foo="foo"
pipeline {
agent none
stages {
   stage("first") {
      script{
          sh "echo ${foo}"
      }
    }
  }
}

Do not forget that you also can pass these use variables by reference.

The use cases are when you need to change the use'd variable from inside of your callback (e.g. produce the new array of different objects from some source array of objects).

$sourcearray = [ (object) ['a' => 1], (object) ['a' => 2]];
$newarray = [];
array_walk($sourcearray, function ($item) use (&$newarray) {
    $newarray[] = (object) ['times2' => $item->a * 2];
});
var_dump($newarray);

Now $newarray will comprise (pseudocode here for brevity) [{times2:2},{times2:4}].

On the contrary, using $newarray with no & modifier would make outer $newarray variable be read-only accessible from within the closure scope. But $newarray within closure scope would be a completelly different newly created variable living only within the closure scope.

Despite both variables' names are the same these would be two different variables. The outer $newarray variable would comprise [] in this case after the code has finishes.

There's another way to loop over objects, using structural directives:

I prefer this approach because it "feels" most like the normal ngFor loop. :-)

(In this case for example I added Angular's context variables let i = index | even | odd | first | last | count) that are accessible inside my loop).

@Directive({
  selector: '[ngForObj]'
})
export class NgForObjDirective implements OnChanges {

  @Input() ngForObjOf: { [key: string]: any };

  constructor(private templateRef: TemplateRef<any>, private viewContainerRef: ViewContainerRef) { }

  ngOnChanges(changes: SimpleChanges): void {
    if (changes.ngForObjOf && changes.ngForObjOf.currentValue) {
      // remove all views
      this.viewContainerRef.clear();

      // create a new view for each property
      const propertyNames = Object.keys(changes.ngForObjOf.currentValue);
      const count = propertyNames.length;

      propertyNames.forEach((key: string, index: number) => {
        const even = ((index % 2) === 0);
        const odd = !even;
        const first = (index === 0);
        const last = index === (count - 1);

        this.viewContainerRef.createEmbeddedView(this.templateRef, {
          $implicit: changes.ngForObjOf.currentValue[key],
          index,
          even,
          odd,
          count,
          first,
          last
        });
      });
    }
  }
}

Usage in your template:

<ng-container *ngForObj="let item of myObject; let i = index"> ... </ng-container>

And if you want to loop using an integer value, you can use this directive:

@Directive({
   selector: '[ngForInt]'
})
export class NgForToDirective implements OnChanges {

  @Input() ngForIntTo: number;
 
  constructor(private templateRef: TemplateRef<any>, private viewContainerRef: ViewContainerRef) {

  }

  ngOnChanges(changes: SimpleChanges): void {
    if (changes.ngForIntTo && changes.ngForIntTo.currentValue) {
      // remove all views
      this.viewContainerRef.clear();

      let currentValue = parseInt(changes.ngForIntTo.currentValue);
      for (let index = 0; index < currentValue; index++) {
        this.viewContainerRef.createEmbeddedView(this.templateRef, {
          $implicit: index,
          index
        });
      }

    }

  }
}

Usage in your template (example: loop from 0 to 14 (= 15 iterations):

<ng-container *ngForInt="let x to 15"> ... </ng-container>

I agree with Scott, what he listed worked. However just running it from any directory did not work. I had to cd to the /home/*/.swt/lib/linux/x86_64/ 0 files

directory first and then run the link command:

For 32 bit:

ln -s /usr/lib/jni/libswt-* ~/.swt/lib/linux/x86/

And on Ubuntu 12.04 64 bit:

ln -s /usr/lib/jni/libswt-* ~/.swt/lib/linux/x86_64/

A simple one liner that works can be done using:

[ "$#" -ne 1 ] && ( usage && exit 1 ) || main

This breaks down to:

1. test the bash variable for size of parameters $# not equals 1 (our number of sub commands)
2. if true then call usage() function and exit with status 1
3. else call main() function

Things to note:

• usage() can just be simple echo "$0: params"
• main can be one long script

I'm guessing that you don't need to re-increment the existing data so, why can't you just run a simple ALTER TABLE command to change the PK's attributes?

Something like:

ALTER TABLE `content` CHANGE `id` `id` SMALLINT( 5 ) UNSIGNED NOT NULL AUTO_INCREMENT 

I've tested this code on my own MySQL database and it works but I have not tried it with any meaningful number of records. Once you've altered the row then you need to reset the increment to a number guaranteed not to interfere with any other records.

ALTER TABLE `content` auto_increment = MAX(`id`) + 1

Again, untested but I believe it will work.

You can create an autofield. Here is the documentation for the same

Please remember Django won't allow to have more than one AutoField in a model, In your model you already have one for your primary key (which is default). So you'll have to override model's save method and will probably fetch the last inserted record from the table and accordingly increment the counter and add the new record.

Please make that code thread safe because in case of multiple requests you might end up trying to insert same value for different new records.

If I get your question correctly, you want to also know the names of the files generated inside the temporary directory? If so, try this:

import os
import tempfile

with tempfile.TemporaryDirectory() as tmp_dir:
    # generate some random files in it
     files_in_dir = os.listdir(tmp_dir)

Headers included with #include <> will be searched in all default directories , but you can also add your own location in the search path with -I command line arg.

I saw your edit you could install your headers in default locations usually

 /usr/local/include
 libdir/gcc/target/version/include
 /usr/target/include
 /usr/include

Confirm with compiler docs though.

You can use Linq

var files = Directory.GetFiles(@"C:\", "*").OrderByDescending(d => new FileInfo(d).CreationTime);

I ran into this same issue. I needed to get the file size and modified date of 90,000 files on a network share. Using Java, and being as minimalistic as possible, it would take a very long time. (I needed to get the URL from the file, and the path of the object as well. So its varied somewhat, but more than an hour.) I then used a native Win32 executable, and did the same task, just dumping the file path, modified, and size to the console, and executed that from Java. The speed was amazing. The native process, and my string handling to read the data could process over 1000 items a second.

So even though people down ranked the above comment, this is a valid solution, and did solve my issue. In my case I knew the folders I needed the sizes of ahead of time, and I could pass that in the command line to my win32 app. I went from hours to process a directory to minutes.

The issue did also seem to be Windows specific. OS X did not have the same issue and could access network file info as fast as the OS could do so.

Java File handling on Windows is terrible. Local disk access for files is fine though. It was just network shares that caused the terrible performance. Windows could get info on the network share and calculate the total size in under a minute too.

James Padolsey created a wonderful filter that allows regex to be used for selection.

Say you have the following div:

<div class="asdf">

Padolsey's :regex filter can select it like so:

$("div:regex(class, .*sd.*)")

Also, check the official documentation on selectors.

UPDATE: : syntax Deprecation JQuery 3.0

Since jQuery.expr[':'] used in Padolsey's implementation is already deprecated and will render a syntax error in the latest version of jQuery, here is his code adapted to jQuery 3+ syntax:

jQuery.expr.pseudos.regex = jQuery.expr.createPseudo(function (expression) {
    return function (elem) {
        var matchParams = expression.split(','),
            validLabels = /^(data|css):/,
            attr = {
                method: matchParams[0].match(validLabels) ?
                    matchParams[0].split(':')[0] : 'attr',
                property: matchParams.shift().replace(validLabels, '')
            },
            regexFlags = 'ig',
            regex = new RegExp(matchParams.join('').replace(/^\s+|\s+$/g, ''), regexFlags);
        return regex.test(jQuery(elem)[attr.method](attr.property));
    }
});

You can use a substring

String word = "onetwotwoone"
int lenght = word.length(); //Note this should be function.
String numbers = word.substring(word.length() - 3);

For all users on a specific database, do the following:

# psql
\c your_database
select grantee, table_catalog, privilege_type, table_schema, table_name from information_schema.table_privileges order by grantee, table_schema, table_name;

I work for a large corporation and encountered this same error, but needed a different work around. My issue was related to proxy settings. I had my proxy set up so I needed to set my no_proxy to whitelist AWS before I was able to get everything to work. You can set it in your bash script as well if you don't want to muddy up your Python code with os settings.

Python:

import os
os.environ["NO_PROXY"] = "s3.amazonaws.com"

Bash:

export no_proxy = "s3.amazonaws.com"

Edit: The above assume a US East S3 region. For other regions: use s3.[region].amazonaws.com where region is something like us-east-1 or us-west-2

1. Export it into some text format. The easiest will probably be a tab-delimited version, but CSV can work as well.

2. Use the load data capability. See http://dev.mysql.com/doc/refman/5.1/en/load-data.html

3. Look half way down the page, as it will gives a good example for tab separated data:

   FIELDS TERMINATED BY '\t' ENCLOSED BY '' ESCAPED BY '\'

4. Check your data. Sometimes quoting or escaping has problems, and you need to adjust your source, import command-- or it may just be easier to post-process via SQL.

Sometimes you will need this :

 /*<![CDATA[*/
 /*]]>*/

and not only this :

 <![CDATA[
 ]]>

For small functions like this you could just count by hand how many hops it is to the target, from the instruction under the branch instruction. If it branches backwards make that hop number negative. if that number doesn't require all 16 bits, then for every number to the left of the most significant of your hop number, make them 1's, if the hop number is positive make them all 0's Since most branches are close to they're targets, this saves you a lot of extra arithmetic for most cases.

If you don't want to create a custom view, you can also change the color like this (requires iOS 6):

-(void) tableView:(UITableView *)tableView willDisplayHeaderView:(UIView *)view forSection:(NSInteger)section {
    if ([view isKindOfClass: [UITableViewHeaderFooterView class]]) {
        UITableViewHeaderFooterView* castView = (UITableViewHeaderFooterView*) view;
        UIView* content = castView.contentView;
        UIColor* color = [UIColor colorWithWhite:0.85 alpha:1.]; // substitute your color here
        content.backgroundColor = color;
    }
}

In addition to the accepted answer. You can use a lambda instead of regex:

from bs4 import BeautifulSoup

html = """<p>test python</p>"""

soup = BeautifulSoup(html, "html.parser")

print(soup(text="python"))
print(soup(text=lambda t: "python" in t))

Output:

[]
['test python']

To dynamically change the color of a text box goto properties, goto font/Color and set the following expression

=SWITCH(Fields!CurrentRiskLevel.Value = "Low", "Green",
Fields!CurrentRiskLevel.Value = "Moderate", "Blue",
Fields!CurrentRiskLevel.Value = "Medium", "Yellow",
Fields!CurrentRiskLevel.Value = "High", "Orange",
Fields!CurrentRiskLevel.Value = "Very High", "Red"
)

Same way for tolerance

=SWITCH(Fields!Tolerance.Value = "Low", "Red",
Fields!Tolerance.Value = "Moderate", "Orange",
Fields!Tolerance.Value = "Medium", "Yellow",
Fields!Tolerance.Value = "High", "Blue",
Fields!Tolerance.Value = "Very High", "Green")

Instead of having two arrays of Strings, have one array of a custom class which contains your two strings.

Lock is a questionable idea in JS which is intended to be threadless and not needing concurrency protection. You're looking to combine calls on deferred execution. The pattern I follow for this is the use of callbacks. Something like this:

var functionLock = false;
var functionCallbacks = [];
var lockingFunction = function (callback) {
    if (functionLock) {
        functionCallbacks.push(callback);
    } else {
        $.longRunning(function(response) {
             while(functionCallbacks.length){
                 var thisCallback = functionCallbacks.pop();
                 thisCallback(response);
             }
        });
    }
}

You can also implement this using DOM event listeners or a pubsub solution.

Where cronjobs is the file that contains your cronjobs, in this form:

* * * * * echo "hello stackoverflow" >> /test_file 2>&1
# remember to end this file with an empty new line

You're missing a few (not terribly clear) steps. Pandas is distributed through pip as a wheel, which means you need to do:

pip install wheel
pip install pandas

You're probably going to run into other issues after this - it looks like you're installing on Windows which isn't the most friendly of targets for numpy/scipy/pandas. Alternatively, you could pickup a binary installer from here.

You also had an error installing numpy. Like before, I recommend grabbing a binary installer for this, as it's not a simple process. However, you can resolve your current error by installing this package from Microsoft.

While it's completely possible to get a perfect environment setup on Windows, I have found the quality-of-life for a Python dev is vastly improved by setting up a debian VM. Especially with the scientific packages, you will run into many cases like this.

The final keyword indicates that a variable may only be initialized once. In your code you are only performing one initialization of final so the terms are satisfied. This statement performs the lone initialization of foo. Note that final != immutable, it only means that the reference cannot change.

foo = new ArrayList();

When you declare foo as static final the variable must be initialized when the class is loaded and cannot rely on instantiation (aka call to constructor) to initialize foo since static fields must be available without an instance of a class. There is no guarantee that the constructor will have been called prior to using the static field.

When you execute your method under the static final scenario the Test class is loaded prior to instantiating t at this time there is no instantiation of foo meaning it has not been initialized so foo is set to the default for all objects which is null. At this point I assume your code throws a NullPointerException when you attempt to add an item to the list.

Console Application is an application (.exe), not a Library (.dll). To make a library, create a new project, select "Class Library" in type of project, then copy the logic of your first code into this new project.

Or you can edit the Project Properties and select Class Library instead of Console Application in Output type.

As some code can be "console" dependant, I think first solution is better if you check your logic when you copy it.

You may come across this message/error, after installing epel-release. The quick fix is to update your SSL certificates:

yum -y upgrade ca-certificates

Chances are the above error may also occur while certificate update, if so, just disable the epel repo i.e. use the following command:

yum -y upgrade ca-certificates --disablerepo=epel 

Once the certificates will be updated, you'll be able to use yum normally, even the epel repo will work fine. In case you're getting this same error for a different repo, just put it's name against the --disablerepo=<repo-name> flag.

Note: use sudo if you're not the root user.

If using @worldofjr answer in jQuery you are getting error:

e.relatedTarget.data is not a function

you should use:

$('#myModal').on('show.bs.modal', function (e) {
    var loadurl = $(e.relatedTarget).data('load-url');
    $(this).find('.modal-body').load(loadurl);
});

Not that e.relatedTarget if wrapped by $(..)

I was getting the error in latest Bootstrap 3 and after using this method it's working without any problem.

Here's what works for me, and is quickest and causes the least amount of pain / annoyance:

1) Paste you code snippet into sublime; make sure your syntax is looking good.

2) Right click and choose 'Copy as RTF'

3) Paste into your email

4) Done

Generally, .c and .h files are for C or C-compatible code, everything else is C++.

Many folks prefer to use a consistent pairing for C++ files: .cpp with .hpp, .cxx with .hxx, .cc with .hh, etc. My personal preference is for .cpp and .hpp.

This is an answer targeting primarily developers using Windows, as the path syntax of the diff tool differs from other platforms.

I use Kdiff3 as the git mergetool, but to set up the git difftool as Meld, I first installed the latest version of Meld from Meldmerge.org then added the following to my global .gitconfig using:

git config --global -e

Note, if you rather want Sublime Text 3 instead of the default Vim as core ditor, you can add this to the .gitconfig file:

[core]
editor = 'c:/Program Files/Sublime Text 3/sublime_text.exe'

Then you add inn Meld as the difftool

[diff]
tool = meld
guitool = meld 

[difftool "meld"]
cmd = \"C:/Program Files (x86)/Meld/Meld.exe\" \"$LOCAL\" \"$REMOTE\" --label \"DIFF 
(ORIGINAL MY)\"
prompt = false
path = C:\\Program Files (x86)\\Meld\\Meld.exe

Note the leading slash in the cmd above, on Windows it is necessary.

It is also possible to set up an alias to show the current git diff with a --dir-diff option. This will list the changed files inside Meld, which is handy when you have altered multiple files (a very common scenario indeed).

The alias looks like this inside the .gitconfig file, beneath [alias] section:

showchanges = difftool --dir-diff

To show the changes I have made to the code I then just enter the following command:

git showchanges

The following image shows how this --dir-diff option can show a listing of changed files (example):

Then it is possible to click on each file and show the changes inside Meld.

In Management Studio, select the database, right-click and select Tasks->Export Data. There you will see options to export to different kinds of formats including CSV, Excel, etc.

You can also run your query from the Query window and save the results to CSV.

You could try something like:

char ch;
fstream fin("file", fstream::in);
while (fin >> noskipws >> ch) {
    cout << ch; // Or whatever
}

On a Mac, you can use terminal to go to /Applications/Android Studio.app/Contents/jre/jdk/Contents/Home (or wherever your Android SDK is installed) and enter the following in the command prompt:

./java -version

getRowRects

Element.getClientRects() works like this

each rects in the same row has the same top value, so find out the rects with different top value, like this

function getRowRects(element) {
    var rects = [],
        clientRects = element.getClientRects(),
        len = clientRects.length,
        clientRect, top, rectsLen, rect, i;

    for(i=0; i<len; i++) {
        has = false;
        rectsLen = rects.length;
        clientRect = clientRects[i];
        top = clientRect.top;
        while(rectsLen--) {
            rect = rects[rectsLen];
            if (rect.top == top) {
                has = true;
                break;
            }
        }
        if(has) {
            rect.right = rect.right > clientRect.right ? rect.right : clientRect.right;
            rect.width = rect.right - rect.left;
        }
        else {
            rects.push({
                top: clientRect.top,
                right: clientRect.right,
                bottom: clientRect.bottom,
                left: clientRect.left,
                width: clientRect.width,
                height: clientRect.height
            });
        }
    }
    return rects;
}

savefig has its own parameter for facecolor. I think an even easier way than the accepted answer is to set them globally just once, instead of putting facecolor=fig.get_facecolor() every time:

plt.rcParams['axes.facecolor']='red'
plt.rcParams['savefig.facecolor']='red'

What about:

datetime.now().strftime('%M:%S.%f')[:-4]

I'm not sure what you mean by "Milliseconds only 2 digits", but this should keep it to 2 decimal places. There may be a more elegant way by manipulating the strftime format string to cut down on the precision as well -- I'm not completely sure.

EDIT

If the %f modifier doesn't work for you, you can try something like:

now=datetime.now()
string_i_want=('%02d:%02d.%d'%(now.minute,now.second,now.microsecond))[:-4]

Again, I'm assuming you just want to truncate the precision.

Width 100% : It will make content with 100%. margin, border, padding will be added to this width and element will overflow if any of these added.

Width auto : It will fit the element in available space including margin, border and padding. space remaining after adjusting margin + padding + border will be available width/ height.

Width 100% + box-sizing: border box : It will also fits the element in available space including border, padding (margin will make it overflow the container).

As I understand it, roles were initially defined by XHTML but were deprecated. However, they are now defined by HTML 5, see here: https://www.w3.org/WAI/PF/aria/roles#abstract_roles_header

The purpose of the role attribute is to identify to parsing software the exact function of an element (and its children) as part of a web application. This is mostly as an accessibility thing for screen readers, but I can also see it as being useful for embedded browsers and screen scrapers. In order to be useful to the unusual HTML client, the attribute needs to be set to one of the roles from the spec I linked. If you make up your own, this 'future' functionality can't work - a comment would be better.

Practicalities here: http://www.accessibleculture.org/articles/2011/04/html5-aria-2011/

Let's assume you want to concatenate string and integer in a situation like this:

for i in range(1,11):
   string="string"+i 

and you are getting type or concatenation error

The best way to go about it is to do something like this:

for i in range(1,11):
   print("string",i)    

This will give you concatenated results like string 1, string 2, string 3 ...etc

You can use Android Intents library for opening your application page at Google Play like that:

Intent intent = IntentUtils.openPlayStore(getApplicationContext());
startActivity(intent);

Or if all borders have same style, just:

border:10px;

They provide the capability to extend existing types by adding new methods with no modifications necessary to the type. Calling methods from objects of the extended type within an application using instance method syntax is known as ‘‘extending’’ methods. Extension methods are not instance members on the type. The key point to remember is that extension methods, defined as static methods, are in scope only when the namespace is explicitly imported into your application source code via the using directive. Even though extension methods are defined as static methods, they are still called using instance syntax.

Check the full example here http://www.dotnetreaders.com/articles/Extension_methods_in_C-sharp.net,Methods_in_C_-sharp/201

Example:

class Extension
    {
        static void Main(string[] args)
        {
            string s = "sudhakar";
            Console.WriteLine(s.GetWordCount());
            Console.ReadLine();
        }

    }
    public static class MyMathExtension
    {

        public static int GetWordCount(this System.String mystring)
        {
            return mystring.Length;
        }
    }

You also need to add /usr/include/libxml2 to your include path.

SQL Server Data Tools in Visual Studio 2015 is a modern development tool that you can download for free to build SQL Server relational databases, Azure SQL databases, Integration Services packages, Analysis Services data models, and Reporting Services reports. With SSDT, you can design and deploy any SQL Server content type with the same ease as you would develop an application in Visual Studio. This release supports SQL Server 2016 through SQL Server 2005, and provides the design environment for adding features that are new in SQL Server 2016.

Note that you don't need to have Visual Studio pre-installed. SSDT will install required components of VS, if it is not installed on your machine.

If you are using Perforce (imported the project as a Perforce project), then .cproject and .project will be located under the root of the PERFORCE project, not on the workspace folder.

Hope this helps :)

What I did is remove the project in local, and re clone the whole project again.

As of the Windows 10 "Anniversary" update (Version 1607), you can now run an Ubuntu subsystem from directly inside of Windows by enabling a feature called Developer mode.

To enable developer mode, go to Start > Settings then typing "Use developer features" in the search box to find the setting. On the left hand navigation, you will then see a tab titled For developers. From within this tab, you will see a radio box to enable Developer mode.

After developer mode is enabled, you will then be able to enable the Linux subsystem feature. To do so, go to Control Panel > Programs > Turn Windows features on or off > and check the box that says Windows Subsystem for Linux (Beta)

Now, rather than using Cygwin or a console emulator, you can run tmux through bash on the Ubuntu subsystem directly from Windows through the traditional apt package (sudo apt-get install tmux).

Another option is:

results = []
for x in [1,2,3]:
    z = add(x,2)
    ...
    results += [f(z,x,y)]

This format is very useful when calling multiple functions.

Array indexes in JavaScript start at zero for the first item, so try this:

var firstArrayItem = myValues[0]

Of course, if you actually want the second item in the array at index 1, then it's myValues[1].

See Accessing array elements for more info.

If you mean you want the background image itself to be offset by 50 pixels from the top, like a background margin, then just switch out the top for 50px and you're set.

#thedivstatus {
    background-image: url("imagestatus.gif");
    background-position: right 50px;
    background-repeat: no-repeat;
}

Perhaps a more realistic example about not sorting a Map object but preparing the sorting up front before doing the Map. The syntax gets actually pretty compact if you do it like this. You can apply the sorting before the map function like this, with a sort function before map (Example from a React app I am working on using JSX syntax)

Mark that I here define a sorting function inside using an arrow function that returns -1 if it is smaller and 0 otherwise sorted on a property of the Javascript objects in the array I get from an API.

report.ProcedureCodes.sort((a, b) => a.NumericalOrder < b.NumericalOrder ? -1 : 0).map((item, i) =>
                        <TableRow key={i}>

                            <TableCell>{item.Code}</TableCell>
                            <TableCell>{item.Text}</TableCell>
                            {/* <TableCell>{item.NumericalOrder}</TableCell> */}
                        </TableRow>
                    )

First open a console then cd to where you've downloaded your file like some-package.whl and use

pip install some-package.whl

Note: if pip.exe is not recognized, you may find it in the "Scripts" directory from where python has been installed. I have multiple Python installations, and needed to use the pip associated with Python 3 to install a version 3 wheel.

If pip is not installed, and you are using Windows: How to install pip on Windows?

You could convert the dataframe to be a single column with stack (this changes the shape from 5x3 to 15x1) and then take the standard deviation:

df.stack().std()         # pandas default degrees of freedom is one

Alternatively, you can use values to convert from a pandas dataframe to a numpy array before taking the standard deviation:

df.values.std(ddof=1)    # numpy default degrees of freedom is zero

Unlike pandas, numpy will give the standard deviation of the entire array by default, so there is no need to reshape before taking the standard deviation.

A couple of additional notes:

• The numpy approach here is a bit faster than the pandas one, which is generally true when you have the option to accomplish the same thing with either numpy or pandas. The speed difference will depend on the size of your data, but numpy was roughly 10x faster when I tested a few different sized dataframes on my laptop (numpy version 1.15.4 and pandas version 0.23.4).

• The numpy and pandas approaches here will not give exactly the same answers, but will be extremely close (identical at several digits of precision). The discrepancy is due to slight differences in implementation behind the scenes that affect how the floating point values get rounded.

You can do this with the "rebase" command. Let's call the branches "main" and "feature":

git checkout feature
git rebase main

The rebase command will replay all of the commits on "feature" as one commit with a parent equal to "main".

You might want to run git merge main before git rebase main if "main" has changed since "feature" was created (or since the most recent merge). That way, you still have your full history in case you had a merge conflict.

After the rebase, you can merge your branch to main, which should result in a fast-forward merge:

git checkout main
git merge feature

See the rebase page of Understanding Git Conceptually for a good overview

When you cherry-pick, it creates a new commit with a new SHA. If you do:

git cherry-pick -x <sha>

then at least you'll get the commit message from the original commit appended to your new commit, along with the original SHA, which is very useful for tracking cherry-picks.

A simple function that blits an image front onto an image back and returns the result. It works with both 3 and 4-channel images and deals with the alpha channel. Overlaps are handled as well.

The output image has the same size as back, but always 4 channels.
The output alpha channel is given by (u+v)/(1+uv) where u,v are the alpha channels of the front and back image and -1 <= u,v <= 1. Where there is no overlap with front, the alpha value from back is taken.

import cv2

def merge_image(back, front, x,y):
    # convert to rgba
    if back.shape[2] == 3:
        back = cv2.cvtColor(back, cv2.COLOR_BGR2BGRA)
    if front.shape[2] == 3:
        front = cv2.cvtColor(front, cv2.COLOR_BGR2BGRA)

    # crop the overlay from both images
    bh,bw = back.shape[:2]
    fh,fw = front.shape[:2]
    x1, x2 = max(x, 0), min(x+fw, bw)
    y1, y2 = max(y, 0), min(y+fh, bh)
    front_cropped = front[y1-y:y2-y, x1-x:x2-x]
    back_cropped = back[y1:y2, x1:x2]

    alpha_front = front_cropped[:,:,3:4] / 255
    alpha_back = back_cropped[:,:,3:4] / 255
    
    # replace an area in result with overlay
    result = back.copy()
    print(f'af: {alpha_front.shape}\nab: {alpha_back.shape}\nfront_cropped: {front_cropped.shape}\nback_cropped: {back_cropped.shape}')
    result[y1:y2, x1:x2, :3] = alpha_front * front_cropped[:,:,:3] + alpha_back * back_cropped[:,:,:3]
    result[y1:y2, x1:x2, 3:4] = (alpha_front + alpha_back) / (1 + alpha_front*alpha_back) * 255

    return result

1. del /s /q c:\where ever the file is\*
2. rmdir /s /q c:\where ever the file is\
3. mkdir c:\where ever the file is\

So here is an other way:

Create a migration file

rails generate migration add_references_to_uploads user:references

Default foreign key name

This would create a user_id column in uploads table as a foreign key

class AddReferencesToUploads < ActiveRecord::Migration[5.2]
  def change
    add_reference :uploads, :user, foreign_key: true
  end
end

user model:

class User < ApplicationRecord
  has_many :uploads
end

upload model:

class Upload < ApplicationRecord
  belongs_to :user
end

Customize foreign key name:

add_reference :uploads, :author, references: :user, foreign_key: true

This would create an author_id column in the uploads tables as the foreign key.

user model:

class User < ApplicationRecord
  has_many :uploads, foreign_key: 'author_id'
end

upload model:

class Upload < ApplicationRecord
  belongs_to :user
end

Date has the time as well, just add HH:mm:ss to the date format:

import java.text.SimpleDateFormat
def date = new Date()
def sdf = new SimpleDateFormat("MM/dd/yyyy HH:mm:ss")
println sdf.format(date)

In case you are using JRE 8 you can use LoaclDateTime:

import java.time.*

LocalDateTime t = LocalDateTime.now();
return t as String

There is an easy way for doing this using git-cli

gh pr checkout {<number> | <url> | <branch>}

Reference: https://cli.github.com/manual/gh_pr_checkout

For Example:

var x = 9.656;
x.toFixed(0);           // returns 10
x.toFixed(2);           // returns 9.66
x.toFixed(4);           // returns 9.6560
x.toFixed(6);           // returns 9.656000 

or

parseInt("10");         // returns 10
parseInt("10.33");      // returns 10
parseInt("10 20 30");   // returns 10
parseInt("10 years");   // returns 10
parseInt("years 10");   // returns NaN  

I recently run into this problem, when trying to count using case when, and found that changing the order of the which and count statements fixes the problem:

SELECT date(dateday) as pick_day,
COUNT(CASE WHEN (apples = 'TRUE' OR oranges 'TRUE') THEN fruit END)  AS fruit_counter

FROM pickings

GROUP BY 1

Instead of using - in the latter, where I got errors that apples and oranges should appear in aggregate functions

CASE WHEN ((apples = 'TRUE' OR oranges 'TRUE') THEN COUNT(*) END) END AS fruit_counter

For those of you who, like me, come to this issue from Django, you should know that the docs provide a solution: https://docs.djangoproject.com/en/1.10/ref/models/fields/#foreignkey

"...To refer to models defined in another application, you can explicitly specify a model with the full application label. For example, if the Manufacturer model above is defined in another application called production, you’d need to use:

class Car(models.Model):
    manufacturer = models.ForeignKey(
        'production.Manufacturer',
        on_delete=models.CASCADE,
)

This sort of reference can be useful when resolving circular import dependencies between two applications...."

Yes. The same notation that works for non-empty dict/set works for empty ones.

Notice the difference between non-empty dict and set literals:

{1: 'a', 2: 'b', 3: 'c'} -- a number of key-value pairs inside makes a dict
{'aaa', 'bbb', 'ccc'} -- a tuple of values inside makes a set

So:

{} == zero number of key-value pairs == empty dict
{*()} == empty tuple of values == empty set

However the fact, that you can do it, doesn't mean you should. Unless you have some strong reasons, it's better to construct an empty set explicitly, like:

a = set()

Performance:

The literal is ~15% faster than the set-constructor (CPython-3.8, 2019 PC, Intel(R) Core(TM) i7-8550U CPU @ 1.80GHz):

>>> %timeit ({*()} & {*()}) | {*()}
214 ns ± 1.26 ns per loop (mean ± std. dev. of 7 runs, 1000000 loops each)

>>> %timeit (set() & set()) | set()
252 ns ± 0.566 ns per loop (mean ± std. dev. of 7 runs, 1000000 loops each)

... and for completeness, Renato Garcia's frozenset proposal on the above expression is some 60% faster!

>>> ? = frozenset()

>>> %timeit (? & ?) | ?
100 ns ± 0.51 ns per loop (mean ± std. dev. of 7 runs, 10000000 loops each)

NB: As ctrueden noticed in comments, {()} is not an empty set. It's a set with 1 element: empty tuple.

In irb:

>>d = DateTime.now
=> #<DateTime: 11783702280454271/4800000000,5/12,2299161>
>> "#{d.hour.to_i - d.zone.to_i}:#{d.min}:#{d.sec}"
=> "11:16:41"

will convert the time to the utc. But as posted if it is just Time you can use:

Time.now.utc

and get it straight away.

All of the other answers here have problems.

The document.createElement('div') methods (including those using jQuery) execute any javascript passed into it (a security issue) and the DOMParser.parseFromString() method trims whitespace. Here is a pure javascript solution that has neither problem:

function htmlDecode(html) {
    var textarea = document.createElement("textarea");
    html= html.replace(/\r/g, String.fromCharCode(0xe000)); // Replace "\r" with reserved unicode character.
    textarea.innerHTML = html;
    var result = textarea.value;
    return result.replace(new RegExp(String.fromCharCode(0xe000), 'g'), '\r');
}

TextArea is used specifically to avoid executig js code. It passes these:

htmlDecode('&lt;&amp;&nbsp;&gt;'); // returns "<& >" with non-breaking space.
htmlDecode('  '); // returns "  "
htmlDecode('<img src="dummy" onerror="alert(\'xss\')">'); // Does not execute alert()
htmlDecode('\r\n') // returns "\r\n", doesn't lose the \r like other solutions.

You should use @RequestParam on those resources with method = RequestMethod.GET

In order to post parameters, you must send them as the request body. A body like JSON or another data representation would depending on your implementation (I mean, consume and produce MediaType).

Typically, multipart/form-data is used to upload files.

The easiest way I found:

<Setter Property="Focusable" Value="false"/>

If you're looking to match non-blank values or empty cells and having difficulty with wildcard character, I found the solution below from here.

Dim n as Integer
n = Worksheets("Sheet1").Range("A:A").Cells.SpecialCells(xlCellTypeConstants).Count

You can use the following code to add column to Datatable at postion 0:

    DataColumn Col   = datatable.Columns.Add("Column Name", System.Type.GetType("System.Boolean"));
    Col.SetOrdinal(0);// to put the column in position 0;

Well, the error message says it all: NumPy arrays do not have an append() method. There's a free function numpy.append() however:

numpy.append(M, a)

This will create a new array instead of mutating M in place. Note that using numpy.append() involves copying both arrays. You will get better performing code if you use fixed-sized NumPy arrays.

sometimes this can cause of a very simple reason, go to your list in eclipse and check whether you have set SDCard size

For anyone that finds this thread in the future, note that the accepted answer will not always return the correct value if you generalize it, since it will choke on regex operators like $ and .. Here's a better version, that can handle any needle:

function occurrences (haystack, needle) {
  var _needle = needle
    .replace(/\[/g, '\\[')
    .replace(/\]/g, '\\]')
  return (
    haystack.match(new RegExp('[' + _needle + ']', 'g')) || []
  ).length
}

Try this.. very easy to understand & implementation...

Select [Column Name] into [New Table] from [Source Table]

You could use a variable to make the calculation and use toFixed when you set the #diskamountUnit element value:

var amount = $("#disk").slider("value") * 1.60;
$("#diskamountUnit").val('$' + amount.toFixed(2));

You can also do that in one step, in the val method call but IMO the first way is more readable:

$("#diskamountUnit").val('$' + ($("#disk").slider("value") * 1.60).toFixed(2));

Andy gave me some good pointers, but I wanted to do it in an even cleaner way. Not to mention that with the 2>&1 >> method PowerShell complained to me about the log file being accessed by another process, i.e. both stderr and stdout trying to lock the file for access, I guess. So here's how I worked it around.

First let's generate a nice filename, but that's really just for being pedantic:

$name = "sync_common"
$currdate = get-date -f yyyy-MM-dd
$logfile = "c:\scripts\$name\log\$name-$currdate.txt"

And here's where the trick begins:

start-transcript -append -path $logfile

write-output "starting sync"
robocopy /mir /copyall S:\common \\10.0.0.2\common 2>&1 | Write-Output
some_other.exe /exeparams 2>&1 | Write-Output
...
write-output "ending sync"

stop-transcript

With start-transcript and stop-transcript you can redirect ALL output of PowerShell commands to a single file, but it doesn't work correctly with external commands. So let's just redirect all the output of those to the stdout of PS and let transcript do the rest.

In fact, I have no idea why the MS engineers say they haven't fixed this yet "due to the high cost and technical complexities involved" when it can be worked around in such a simple way.

Either way, running every single command with start-process is a huge clutter IMHO, but with this method, all you gotta do is append the 2>&1 | Write-Output code to each line which runs external commands.

Change the CorsMapping from registry.addMapping("/*") to registry.addMapping("/**") in addCorsMappings method.

Check out this Spring CORS Documentation .

From the documentation -

Enabling CORS for the whole application is as simple as:

@Configuration
@EnableWebMvc
public class WebConfig extends WebMvcConfigurerAdapter {

    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/**");
    }
}

You can easily change any properties, as well as only apply this CORS configuration to a specific path pattern:

@Configuration
@EnableWebMvc
public class WebConfig extends WebMvcConfigurerAdapter {
    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/api/**")
            .allowedOrigins("http://domain2.com")
            .allowedMethods("PUT", "DELETE")
            .allowedHeaders("header1", "header2", "header3")
            .exposedHeaders("header1", "header2")
            .allowCredentials(false).maxAge(3600);
    }
}

Controller method CORS configuration

@RestController
@RequestMapping("/account")
public class AccountController {
  @CrossOrigin
  @RequestMapping("/{id}")
  public Account retrieve(@PathVariable Long id) {
    // ...
  }
}

To enable CORS for the whole controller -

@CrossOrigin(origins = "http://domain2.com", maxAge = 3600)
@RestController
@RequestMapping("/account")
public class AccountController {

    @RequestMapping("/{id}")
    public Account retrieve(@PathVariable Long id) {
        // ...
    }

    @RequestMapping(method = RequestMethod.DELETE, path = "/{id}")
    public void remove(@PathVariable Long id) {
        // ...
    }
}

You can even use both controller-level and method-level CORS configurations; Spring will then combine attributes from both annotations to create merged CORS configuration.

@CrossOrigin(maxAge = 3600)
@RestController
@RequestMapping("/account")
public class AccountController {

    @CrossOrigin("http://domain2.com")
    @RequestMapping("/{id}")
    public Account retrieve(@PathVariable Long id) {
        // ...
    }

    @RequestMapping(method = RequestMethod.DELETE, path = "/{id}")
    public void remove(@PathVariable Long id) {
        // ...
    }
}

To me this is just one of many idiosyncracies (emphasis on the idio(t) ) of typescript that causes people to pull out their hair and curse the developers. Maybe they could work on coming up with more understandable error messages.

Just to complete JJC answer, in python 3.5.3 the behavior is correct if you use hashlib this way:

$ python3 -c '
import hashlib
hash_object = hashlib.sha256(b"Caroline")
hex_dig = hash_object.hexdigest()
print(hex_dig)
'
739061d73d65dcdeb755aa28da4fea16a02b9c99b4c2735f2ebfa016f3e7fded
$ python3 -c '
import hashlib
hash_object = hashlib.sha256(b"Caroline")
hex_dig = hash_object.hexdigest()
print(hex_dig)
'
739061d73d65dcdeb755aa28da4fea16a02b9c99b4c2735f2ebfa016f3e7fded

$ python3 -V
Python 3.5.3

Machine learning packages like tensorflow 2.x are designed to work only on 64 bit Python as they are memory intensive.

For Python 3.x, use input(). For Python 2.x, use raw_input(). Don't forget you can add a prompt string in your input() call to create one less print statement. input("GUESS THAT NUMBER!").
