Simply You can use following methods.

using (WebClient client = new WebClient()) 
{
    client.DownloadFile(new Uri(url), @"c:\temp\image35.png");
    // OR 
    client.DownloadFileAsync(new Uri(url), @"c:\temp\image35.png");
}

These methods are almost same as DownloadString(..) and DownloadStringAsync(...). They store the file in Directory rather than in C# string and no need of Format extension in URi

If You don't know the Format(.png, .jpeg etc) of Image

public void SaveImage(string filename, ImageFormat format)
{    
    WebClient client = new WebClient();
    Stream stream = client.OpenRead(imageUrl);
    Bitmap bitmap;  bitmap = new Bitmap(stream);

    if (bitmap != null)
    {
        bitmap.Save(filename, format);
    }

    stream.Flush();
    stream.Close();
    client.Dispose();
}

Using it

try
{
    SaveImage("--- Any Image Path ---", ImageFormat.Png)
}
catch(ExternalException)
{
    // Something is wrong with Format -- Maybe required Format is not 
    // applicable here
}
catch(ArgumentNullException)
{   
    // Something wrong with Stream
}

You could use the SizeMode property of the PictureBox Control and set it to Center. This will match the center of your image to the center of your picture box.

pictureBox1.SizeMode = PictureBoxSizeMode.CenterImage;

Hope it could help.

You can add them in your htaccess file or vhost configuration.

See here : http://httpd.apache.org/docs/2.2/mod/mod_expires.html

But unless you own those domains .. they are our of your control.

replot

This is another way to get multiple plots at once:

plot file1.data
replot file2.data

override func viewDidLoad() {
    super.viewDidLoad()
    self.view.backgroundColor = UIColor(patternImage: UIImage(named: "background.png"))
}

For clarification here. In case you are not using ComponentFactoryResolver directly in component, and you want to abstract it to service, which is then injected into component you have to load it under providers for that module, since if lazy loaded it won't work.

No need to close the file according to the docs if you use with:

It is good practice to use the with keyword when dealing with file objects. This has the advantage that the file is properly closed after its suite finishes, even if an exception is raised on the way. It is also much shorter than writing equivalent try-finally blocks:

>>> with open('workfile', 'r') as f:
...     read_data = f.read()
>>> f.closed
True

More here: https://docs.python.org/2/tutorial/inputoutput.html#methods-of-file-objects

-u no doesn't show unstaged files either. -uno works as desired and shows unstaged, but hides untracked.

There should be templates already included in Visio 2007 for software architecture but you might want to check out Visio 2007 templates.

There are some really good suggestions on here.

Referring to the last screenshot that Mina provided, after initially archiving my app, the provisioning profile mentioned during uploading contained a wildcard (XC.*). This is wrong.

It took some considerable effort in order to resolve this. I had to perform a combination of the suggestions that Simon Woodside & Mina Fawzy provided.

If you have any existing certificates and provisioning profiles related to your project, now would be a good time to remove them all locally, and revoke them all remotely. Give yourself a fresh start.

Mina Fawzy's detailed suggestion is excellent. Performing Mina's suggestion, if performed correctly, should take care of you online.

Enter Simon's suggestion. Two things I needed to check inside my project. Using XCode, go here:

PROJECT -> BUILD SETTINGS -> CODE SIGNING

Review the Code Signing Identity and Provisioning Profile properties. Make sure you set those two properties to that of your project name. Don't allow XCode to automatically select for you, and don't use some generic code signing identity (e.g. Iphone Developer).

Make sure you can actually install the app onto your devices before deciding to archive.

$("element").data('bs.modal').isShown

won't work if the modal hasn't been shown before. You will need to add an extra condition:

$("element").data('bs.modal')

so the answer taking into account first appearance:

if ($("element").data('bs.modal') && $("element").data('bs.modal').isShown){
... 
}

This must be the easiest way to hide your keyboard by touching outside :

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
    [self.view endEditing:YES];    
}

(from How to dismiss keyboard when user tap other area outside textfield?)

This will return TRUE for #VALUE! errors (ERROR.TYPE = 3) and FALSE for anything else.

=IF(ISERROR(A1),ERROR.TYPE(A1)=3)

If the style was declared inline or with JavaScript, you can just get at the style object:

return element.style.display === 'block';

Otherwise, you'll have to get the computed style, and there are browser inconsistencies. IE uses a simple currentStyle object, but everyone else uses a method:

return element.currentStyle ? element.currentStyle.display :
                              getComputedStyle(element, null).display;

The null was required in Firefox version 3 and below.

for React Native 0.49 and over

you should go to project directory on terminal and run that command

1 - mkdir android/app/src/main/assets
2 - react-native bundle --platform android --dev false --entry-file index.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res

if under 0.49

  1 - mkdir android/app/src/main/assets
  2 - react-native bundle --platform android --dev false --entry-file index.android.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res

Then Use android studio to open the 'android' folder in you react native app directory, it will ask to upgrade gradle and some other stuff. go to build-> Generate signed APK and follow the instructions from there. That okey.

The problem, in my case, was that some install at some point defined an environment variable http_proxy on my machine when I had no proxy.

Removing the http_proxy environment variable fixed the problem.

If you use that forumla in the name manager you are creating a dynamic range which uses "this sheet" in place of a specific sheet.

As Jerry says, Sheet1!A1 refers to cell A1 on Sheet1. If you create a named range and omit the Sheet1 part you will reference cell A1 on the currently active sheet. (omitting the sheet reference and using it in a cell formula will error).

edit: my bad, I was using $A$1 which will lock it to the A1 cell as above, thanks pnuts :p

Example downloader class without Alamofire:

class Downloader {
    class func load(URL: NSURL) {
        let sessionConfig = NSURLSessionConfiguration.defaultSessionConfiguration()
        let session = NSURLSession(configuration: sessionConfig, delegate: nil, delegateQueue: nil)
        let request = NSMutableURLRequest(URL: URL)
        request.HTTPMethod = "GET"
        let task = session.dataTaskWithRequest(request, completionHandler: { (data: NSData!, response: NSURLResponse!, error: NSError!) -> Void in
            if (error == nil) {
                // Success
                let statusCode = (response as NSHTTPURLResponse).statusCode
                println("Success: \(statusCode)")

                // This is your file-variable:
                // data
            }
            else {
                // Failure
                println("Failure: %@", error.localizedDescription);
            }
        })
        task.resume()
    }
}

This is how to use it in your own code:

class Foo {
    func bar() {
        if var URL = NSURL(string: "http://www.mywebsite.com/myfile.pdf") {
            Downloader.load(URL)
        }
    }
}

Swift 3 Version

Also note to download large files on disk instead instead in memory. see `downloadTask:

class Downloader {
    class func load(url: URL, to localUrl: URL, completion: @escaping () -> ()) {
        let sessionConfig = URLSessionConfiguration.default
        let session = URLSession(configuration: sessionConfig)
        let request = try! URLRequest(url: url, method: .get)

        let task = session.downloadTask(with: request) { (tempLocalUrl, response, error) in
            if let tempLocalUrl = tempLocalUrl, error == nil {
                // Success
                if let statusCode = (response as? HTTPURLResponse)?.statusCode {
                    print("Success: \(statusCode)")
                }

                do {
                    try FileManager.default.copyItem(at: tempLocalUrl, to: localUrl)
                    completion()
                } catch (let writeError) {
                    print("error writing file \(localUrl) : \(writeError)")
                }

            } else {
                print("Failure: %@", error?.localizedDescription);
            }
        }
        task.resume()
    }
}

A dictionary is something like an array that's accessed by keys (e.g. strings,...) rather than just plain sequential numbers. It contains key/value pairs, you can look up values using a key like using a phone book: key=name, number=value.

For defining such a dictionary, you use this syntax using curly braces, see also: http://wiki.python.org/moin/SimplePrograms

You can upgrade to Subversion 1.7. In order to update to Subversion 1.7 you have to launch existing project in Xcode 5 or above. This will prompt an warning ‘The working copy ProjectName should be upgraded to Subversion 1.7’ (shown in below screenshot).

You should select ‘Upgrade’ button to upgrade to Subversion 1.7. This will take a bit of time.

If you are using terminal then you can upgrade to Subversion 1.7 by running below command in your project directory: svn upgrade

Note that once you have upgraded to Subversion 1.7 you cannot go back to Subversion 1.6.

Refer Apple docs for more details.

Programming the Mandelbrot is easy.
My quick-n-dirty code is below (not guaranteed to be bug-free, but a good outline).

Here's the outline: The Mandelbrot-set lies in the Complex-grid completely within a circle with radius 2.

So, start by scanning every point in that rectangular area. Each point represents a Complex number (x + yi). Iterate that complex number:

[new value] = [old-value]^2 + [original-value] while keeping track of two things:

1.) the number of iterations

2.) the distance of [new-value] from the origin.

If you reach the Maximum number of iterations, you're done. If the distance from the origin is greater than 2, you're done.

When done, color the original pixel depending on the number of iterations you've done. Then move on to the next pixel.

public void MBrot()
{
    float epsilon = 0.0001; // The step size across the X and Y axis
    float x;
    float y;
    int maxIterations = 10; // increasing this will give you a more detailed fractal
    int maxColors = 256; // Change as appropriate for your display.

    Complex Z;
    Complex C;
    int iterations;
    for(x=-2; x<=2; x+= epsilon)
    {
        for(y=-2; y<=2; y+= epsilon)
        {
            iterations = 0;
            C = new Complex(x, y);
            Z = new Complex(0,0);
            while(Complex.Abs(Z) < 2 && iterations < maxIterations)
            {
                Z = Z*Z + C;
                iterations++;
            }
            Screen.Plot(x,y, iterations % maxColors); //depending on the number of iterations, color a pixel.
        }
    }
}

Some details left out are:

1.) Learn exactly what the Square of a Complex number is and how to calculate it.

2.) Figure out how to translate the (-2,2) rectangular region to screen coordinates.

As noted above the problem is in specifying the path to your file. The default path in OS X is your home directory (/Users/macbook represented by ~ in terminal ...you can change or rename the home directory with the advanced options in System Preferences > Users & Groups).

Or you can specify the path from the drive to your file in the filename:

path = "/Users/macbook/Documents/MyPython/"
myFile = path + fileName

You can also catch the File Not Found Error and give another response using try:

try:
    with open(filename) as f:
        sequences = pick_lines(f)
except FileNotFoundError:
    print("File not found. Check the path variable and filename")
    exit()

For this problem, I resolved it by deleting the .user file which contains the Visual Studio Project User Options. This File can be found in the same place where your .sln file is located. Also, after deleting this file from the project make sure to reload your solution in order for it to take effect.

Old answers stopped working in new android versions. Now I use the following:

adb shell "dumpsys activity activities | grep ResumedActivity"

Check out ZBar reads QR Code and ECN/ISBN codes and is available as under the LGPL v2 license.

To prevent the problem from occurring, you must perform a graceful shutdown of the server from the command line rather than powering off the server.

# shutdown -h now

This will stop the running services before powering down the machine.

Based on Centos, an additional method for getting it back up again when you run into this problem is to move mysql.sock:

# mv /var/lib/mysql/mysql.sock /var/lib/mysql/mysql.sock.bak

# service mysqld start

Restarting the service creates a new entry called mqsql.sock

xhr.getResponseHeader('Set-Cookie');

It won't work for me.

I use this

function getCookie(cname) {
    var name = cname + "=";
    var ca = document.cookie.split(';');
    for(var i=0; i<ca.length; i++) {
        var c = ca[i];
        while (c.charAt(0)==' ') c = c.substring(1);
        if (c.indexOf(name) != -1) return c.substring(name.length,c.length);
    }
    return "";
} 

success: function(output, status, xhr) {
    alert(getCookie("MyCookie"));
},

http://www.w3schools.com/js/js_cookies.asp

I'm going to add to the existing answers because modern C++ is now a thing and official Core Guidelines have been created to help with questions such as these.

Here's a relevant section from the guidelines:

C.2: Use class if the class has an invariant; use struct if the data members can vary independently

An invariant is a logical condition for the members of an object that a constructor must establish for the public member functions to assume. After the invariant is established (typically by a constructor) every member function can be called for the object. An invariant can be stated informally (e.g., in a comment) or more formally using Expects.

If all data members can vary independently of each other, no invariant is possible.

If a class has any private data, a user cannot completely initialize an object without the use of a constructor. Hence, the class definer will provide a constructor and must specify its meaning. This effectively means the definer need to define an invariant.

Enforcement

Look for structs with all data private and classes with public members.

The code examples given:

struct Pair {  // the members can vary independently
    string name;
    int volume;
};

// but

class Date {
public:
    // validate that {yy, mm, dd} is a valid date and initialize
    Date(int yy, Month mm, char dd);
    // ...
private:
    int y;
    Month m;
    char d;    // day
};

Classes work well for members that are, for example, derived from each other or interrelated. They can also help with sanity checking upon instantiation. Structs work well for having "bags of data", where nothing special is really going on but the members logically make sense being grouped together.

From this, it makes sense that classes exist to support encapsulation and other related coding concepts, that structs are simply not very useful for.

You want a config.site file. Try:

$ mkdir -p ~/local/share
$ cat << EOF > ~/local/share/config.site
CPPFLAGS=-I$HOME/local/include
LDFLAGS=-L$HOME/local/lib
...
EOF

Whenever you invoke an autoconf generated configure script with --prefix=$HOME/local, the config.site will be read and all the assignments will be made for you. CPPFLAGS and LDFLAGS should be all you need, but you can make any other desired assignments as well (hence the ... in the sample above). Note that -I flags belong in CPPFLAGS and not in CFLAGS, as -I is intended for the pre-processor and not the compiler.

I resolved this by adding @Transactional to the base/generic Hibernate DAO implementation class (the parent class which implements the saveOrUpdate() method inherited by the DAO I use in the main program), i.e. the @Transactional needs to be specified on the actual class which implements the method. My assumption was instead that if I declared @Transactional on the child class then it included all of the methods that were inherited by the child class. However it seems that the @Transactional annotation only applies to methods implemented within a class and not to methods inherited by a class.

Why don't you want to use the back stack? If there is an underlying problem or confusion maybe we can clear it up for you.

If you want to stick with your requirement just override your Activity's onBackPressed() method and call whatever method you're calling when the back arrow in your ActionBar gets clicked.

EDIT: How to solve the "black screen" fragment back stack problem:

You can get around that issue by adding a backstack listener to the fragment manager. That listener checks if the fragment back stack is empty and finishes the Activity accordingly:

You can set that listener in your Activity's onCreate method:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    FragmentManager fm = getFragmentManager();
    fm.addOnBackStackChangedListener(new OnBackStackChangedListener() {
        @Override
        public void onBackStackChanged() {
            if(getFragmentManager().getBackStackEntryCount() == 0) finish();
        }
    });
}

In Visual Studio 2017, "TestContext" doesn't show the Output link into Test Explorer.

However, Trace.Writeline() shows the Output link.

Here is an Offical tutorial of how to that!

Hope help for your!

The easiest way would be to delete the plugins folder. Run this command: cordova prepare But, before you run it, you can check each plugin's version that you think would work for your build on Cordova's plugin repository website, and then you should modify the config.xml file, manually. Use upper carrots, "^" in the version field of the universal modeling language file, "config," to indicate that you want the specified plugin to update to the latest version in the future (the next time you run the command.)

Will www.example.com be able to set cookie for .com?

No, but example.com.fr may be able to set a cookie for example2.com.fr. Firefox protects against this by maintaining a list of TLDs: http://securitylabs.websense.com/content/Blogs/3108.aspx

Apparently Internet Explorer doesn't allow two-letter domains to set cookies, which I suppose explains why o2.ie simply redirects to o2online.ie. I'd often wondered that.

With Apache Commons IO you can do this in one line.

IOUtils.toString(request.getReader())

var x = document.getElementsByClassName("class name");
if (x[0]) {
alert('has');
} else {
alert('no has');
}

While many options above function well, I found coercion of non-target variables to chr problematic. Using ifelse and grepl within lapply resolves this off-target effect (in limited testing). Using slarky's regular expression in grepl:

set.seed(42)
x1 <- sample(c("a","b"," ", "a a", NA), 10, TRUE)
x2 <- sample(c(rnorm(length(x1),0, 1), NA), length(x1), TRUE)

df <- data.frame(x1, x2, stringsAsFactors = FALSE)

The problem of coercion to character class:

df2 <- lapply(df, function(x) gsub("^$|^ $", NA, x))
lapply(df2, class)

$x1 [1] "character"

$x2 [1] "character"

Resolution with use of ifelse:

df3 <- lapply(df, function(x) ifelse(grepl("^$|^ $", x)==TRUE, NA, x))
lapply(df3, class)

$x1 [1] "character"

$x2 [1] "numeric"

Many way to Json Parse but i have found most effective way to

 @model  List<string[]>

     <script>

         function DataParse() {
             var model = '@Html.Raw(Json.Encode(Model))';
             var data = JSON.parse(model);  

            for (i = 0; i < data.length; i++) {
            ......
             }

     </script>

You have to initialise the object (create the object itself) in order to be able to call its methods otherwise you would get a NullPointerException.

WordList words = new WordList();

To get Consumer Key & Consumer Secret, you have to create an app in Twitter via

https://developer.twitter.com/en/apps

Then you'll be taken to a page containing Consumer Key & Consumer Secret.

Hopefully this information will clarify OAuth essentials for Twitter:

1. Create a Twitter account if you don't already have one
2. Visit 'https://apps.twitter.com' and follow the required prompts to create a developer project (Twitter requires you to answer some questions before they will approve your account. Approval was nearly instant in my case.)
3. Requesting the API key and secret via the Developer Portal causes Twitter to produce the following three things:

• API key (this is your 'consumer key')
• API secret key (this is your 'consumer secret')
• Bearer token

4. Next, visit the 'Authentication Tokens' area of the Developer Portal and generate an 'Access token & secret'. This will provide you with the following two items:

• Access token (this is your 'token key')
• Access token secret (this is your 'token secret')

5. The consumer key, consumer secret, token key, and token secret should be sufficient to do Twitter API calls (they were for me). Good luck!

Great answer, "mu is too short". I was seeking the exact same thing, and after reading your post I found a solution that fitted my problem.

I was having two elements of the exact same size and wanted to stack them. As each have same size, what I could do was to make

position: absolute;
top: 0px;
left: 0px;

on only the last element. This way the first element is inserted correctly, "pushing" the parents height, and the second element is placed on top.

Hopes this helps other people trying to stacking 2+ elements with same (unknown) height.

I needed to do many very simple XML requests and after reading @Ivan Krechetov's comment about the speed hit of SOAP, I tried his code and discovered http_post_data() is not built into PHP 5.2. Not really wanting to install it, I tried cURL which is on all my servers. Although I do not know how fast cURL is compared to SOAP, it sure was easy to do what I needed. Below is a sample with cURL for anyone needing it.

$xml_data = '<?xml version="1.0" encoding="UTF-8" ?>
<priceRequest><customerNo>123</customerNo><password>abc</password><skuList><SKU>99999</SKU><lineNumber>1</lineNumber></skuList></priceRequest>';
$URL = "https://test.testserver.com/PriceAvailability";

$ch = curl_init($URL);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: text/xml'));
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "$xml_data");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$output = curl_exec($ch);
curl_close($ch);


print_r($output);

<div style="height: 100px;"> </div>

OR

<div id="foo"/> and set the style as #foo { height: 100px; }
<div class="bar"/> and set the style as .bar{ height: 100px;  }

Most common AD default design is to have a container, cn=users just after the root of the domain. Thus a DN might be:

cn=admin,cn=users,DC=domain,DC=company,DC=com

Also, you might have sufficient rights in an LDAP bind to connect anonymously, and query for (cn=admin). If so, you should get the full DN back in that query.

So there 2 ways to create a dict :

1. my_dict = dict()

2. my_dict = {}

But out of these two options {} is more efficient than dict() plus its readable. CHECK HERE

Having created my own emulator of the BBC Microcomputer of the 80s (type VBeeb into Google), there are a number of things to know.

• You're not emulating the real thing as such, that would be a replica. Instead, you're emulating State. A good example is a calculator, the real thing has buttons, screen, case etc. But to emulate a calculator you only need to emulate whether buttons are up or down, which segments of LCD are on, etc. Basically, a set of numbers representing all the possible combinations of things that can change in a calculator.
• You only need the interface of the emulator to appear and behave like the real thing. The more convincing this is the closer the emulation is. What goes on behind the scenes can be anything you like. But, for ease of writing an emulator, there is a mental mapping that happens between the real system, i.e. chips, displays, keyboards, circuit boards, and the abstract computer code.
• To emulate a computer system, it's easiest to break it up into smaller chunks and emulate those chunks individually. Then string the whole lot together for the finished product. Much like a set of black boxes with inputs and outputs, which lends itself beautifully to object oriented programming. You can further subdivide these chunks to make life easier.

Practically speaking, you're generally looking to write for speed and fidelity of emulation. This is because software on the target system will (may) run more slowly than the original hardware on the source system. That may constrain the choice of programming language, compilers, target system etc.
Further to that you have to circumscribe what you're prepared to emulate, for example its not necessary to emulate the voltage state of transistors in a microprocessor, but its probably necessary to emulate the state of the register set of the microprocessor.
Generally speaking the smaller the level of detail of emulation, the more fidelity you'll get to the original system.
Finally, information for older systems may be incomplete or non-existent. So getting hold of original equipment is essential, or at least prising apart another good emulator that someone else has written!

The option tag does not support rgba colors yet.

With React Navigation v5, just use the navigate method. From the docs:

To achieve this, you can use the navigate method, which acts like goBack if the screen already exists. You can pass the params with navigate to pass the data back

Full example:

import React from 'react';
import { StyleSheet, Button, Text, View } from 'react-native';

import { NavigationContainer } from '@react-navigation/native';
import { createStackNavigator } from '@react-navigation/stack';

const Stack = createStackNavigator();

function ScreenA ({ navigation, route }) {
  const { params } = route;

  return (
    <View style={styles.container}>
      <Text>Params: {JSON.stringify(params)}</Text>
      <Button title='Go to B' onPress={() => navigation.navigate('B')} />
    </View>
  );
}

function ScreenB ({ navigation }) {
  return (
    <View style={styles.container}>
      <Button title='Go to A'
        onPress={() => {
          navigation.navigate('A', { data: 'Something' })
        }}
      />
    </View>
  );
}

export default function App() {
  return (
    <NavigationContainer>
      <Stack.Navigator mode="modal">
        <Stack.Screen name="A" component={ScreenA} />
        <Stack.Screen name="B" component={ScreenB} />
      </Stack.Navigator>
    </NavigationContainer>
  );
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    backgroundColor: '#fff',
    alignItems: 'center',
    justifyContent: 'center',
  },
});

Félix's answer is correct and upvoted, backed-up by Dan Abramov himself.

But for those who would like to change the structure of the output itself (within the build folder), one can run post-build commands with the help of postbuild, which automatically runs after the build script defined in the package.json file.

The example below changes it from static/ to user/static/, moving files and updating file references on relevant files (full gist here):

package.json

{
  "name": "your-project",
  "version": "0.0.1",
  [...]
  "scripts": {
    "build": "react-scripts build",
    "postbuild": "./postbuild.sh",
    [...]
  },
}

postbuild.sh

#!/bin/bash

# The purpose of this script is to do things with files generated by
# 'create-react-app' after 'build' is run.
# 1. Move files to a new directory called 'user'
#    The resulting structure is 'build/user/static/<etc>'
# 2. Update reference on generated files from
#    static/<etc>
#     to
#    user/static/<etc>
#
# More details on: https://github.com/facebook/create-react-app/issues/3824

# Browse into './build/' directory
cd build
# Create './user/' directory
echo '1/4 Create "user" directory'
mkdir user
# Find all files, excluding (through 'grep'):
# - '.',
# - the newly created directory './user/'
# - all content for the directory'./static/'
# Move all matches to the directory './user/'
echo '2/4 Move relevant files'
find . | grep -Ev '^.$|^.\/user$|^.\/static\/.+' | xargs -I{} mv -v {} user
# Browse into './user/' directory
cd user
# Find all files within the folder (not subfolders)
# Replace string 'static/' with 'user/static/' on all files that match the 'find'
# ('sed' requires one to create backup files on OSX, so we do that)
echo '3/4 Replace file references'
find . -type f -maxdepth 1 | LC_ALL=C xargs -I{} sed -i.backup -e 's,static/,user/static/,g' {}
# Delete '*.backup' files created in the last process
echo '4/4 Clean up'
find . -name '*.backup' -type f -delete
# Done

This post is not going to answer to Coppermill, because he have been answered long time ago. My post will be helpful for who will seeking for solution like this. First of all , I have to say " WDuffy's solution is totally correct" and it works fine, but my solution (not actually mine) will be used in other elements and it makes the presentation layer more independent from controller (because your controller depend on "value" which is used for showing label of the button, this feature is important for other languages.).

Here is my solution, give them different names:

<input type="submit" name="buttonSave" value="Save"/>
<input type="submit" name="buttonProcess" value="Process"/>
<input type="submit" name="buttonCancel" value="Cancel"/>

And you must specify the names of buttons as arguments in the action like below:

public ActionResult Register(string buttonSave, string buttonProcess, string buttonCancel)
{
    if (buttonSave!= null)
    {
        //save is pressed
    }
    if (buttonProcess!= null)
    {
        //Process is pressed
    }
    if (buttonCancel!= null)
    {
        //Cancel is pressed
    }
}

when user submits the page using one of the buttons, only one of the arguments will have value. I guess this will be helpful for others.

Update

This answer is quite old and I actually reconsider my opinion . maybe above solution is good for situation which passing parameter to model's properties. don't bother yourselves and take best solution for your project.

Try using a StringBuilder object and use the appendline method. That might work.

I take it you are creating the TextBox in XAML?

In that case, you need to give the text box a name. Then in the code-behind you can then set the Background property using a variety of brushes. The simplest of which is the SolidColorBrush:

myTextBox.Background = new SolidColorBrush(Colors.White);

I doubt anything is killing the process just because it takes a long time. Killed generically means something from the outside terminated the process, but probably not in this case hitting Ctrl-C since that would cause Python to exit on a KeyboardInterrupt exception. Also, in Python you would get MemoryError exception if that was the problem. What might be happening is you're hitting a bug in Python or standard library code that causes a crash of the process.

probably you forgot to add "Export" in the class definition.

-->

export class Hero {
     id: number;
     name: string;
   }

Also, try with

export {Hero} 

at the bottom of your hero.ts class, and finally, check capital letter file name and class name.

As the official docs of redux suggest, better to export the unconnected component as well.

In order to be able to test the App component itself without having to deal with the decorator, we recommend you to also export the undecorated component:

import { connect } from 'react-redux'

// Use named export for unconnected component (for tests)
export class App extends Component { /* ... */ }
 
// Use default export for the connected component (for app)
export default connect(mapStateToProps)(App)

Since the default export is still the decorated component, the import statement pictured above will work as before so you won't have to change your application code. However, you can now import the undecorated App components in your test file like this:

// Note the curly braces: grab the named export instead of default export
import { App } from './App'

And if you need both:

import ConnectedApp, { App } from './App'

In the app itself, you would still import it normally:

import App from './App'

You would only use the named export for tests.

You can use conda remove --force.

The documentation says:

--force               Forces removal of a package without removing packages
                      that depend on it. Using this option will usually
                      leave your environment in a broken and inconsistent
                      state

According to Docker documentation

To use a different shell, other than ‘/bin/sh’, use the exec form passing in the desired shell. For example,

RUN ["/bin/bash", "-c", "echo hello"]

See https://docs.docker.com/engine/reference/builder/#run

You can use this:

function sanitize(string) {
  const map = {
      '&': '&',
      '<': '&lt;',
      '>': '&gt;',
      '"': '&quot;',
      "'": '&#x27;',
      "/": '&#x2F;',
  };
  const reg = /[&<>"'/]/ig;
  return string.replace(reg, (match)=>(map[match]));
}

Also see OWASP XSS Prevention Cheat Sheet.

I found the following solution:

public static Double getFloatAsDouble(Float fValue) {
    return Double.valueOf(fValue.toString());
}

If you use float and double instead of Float and Double use the following:

public static double getFloatAsDouble(float value) {
    return Double.valueOf(Float.valueOf(value).toString()).doubleValue();
}

>>> import os
>>> os.path.abspath("mydir/myfile.txt")
'C:/example/cwd/mydir/myfile.txt'

Also works if it is already an absolute path:

>>> import os
>>> os.path.abspath("C:/example/cwd/mydir/myfile.txt")
'C:/example/cwd/mydir/myfile.txt'

As of April 2018, Chrome (along with several other major browsers) now require the muted attribute too.

Therefore, you should use

<video width="320" height="240" autoplay loop muted>
  <source src="movie.mp4" type="video/mp4" />
</video>

I realise that this is a rather old post and you have probably moved on.

But I had the same problem as you so I decided to write my own program.

The problem with the "xml -> xsd -> classes" route for me was that it just generated a lump of code that was completely unmaintainable and I ended up turfing it.

It is in no way elegant but it did the job for me.

SimpleXmlToCode

I know its kind of too late and proly every one got the answer. But little bit more to add to this: when GenerateType is set, persist() on an object is expected to get an id generated.

If there is a value set to the Id by user already, hibernate treats it as saved record and so it is treated as detached.

if the id is null - in this situation a null pointer exception is raised when the type is AUTO or IDENTITY etc unless the id is generated from a table or a sequece etc.

design: this happens when the table has a bean property as primary key. GenerateType must be set only when an id is autogenerated. remove this and the insert should work with the user specified id. (it is a bad design to have a property mapped to primary key field)

These are positional arguments of the script.

Executing

./script.sh Hello World

Will make

$0 = ./script.sh
$1 = Hello
$2 = World

Note

If you execute ./script.sh, $0 will give output ./script.sh but if you execute it with bash script.sh it will give output script.sh.

So many answers, yet ALL fail to pinpoint one very significant problem with a custom generic ForEach extension: Performance! And more specifically, memory usage and GC.

Consider the sample below. Targeting .NET Framework 4.7.2 or .NET Core 3.1.401, configuration is Release and platform is Any CPU.

public static class Enumerables
{
    public static void ForEach<T>(this IEnumerable<T> @this, Action<T> action)
    {
        foreach (T item in @this)
        {
            action(item);
        }
    }
}

class Program
{
    private static void NoOp(int value) {}

    static void Main(string[] args)
    {
        var list = Enumerable.Range(0, 10).ToList();
        for (int i = 0; i < 1000000; i++)
        {
            // WithLinq(list);
            // WithoutLinqNoGood(list);
            WithoutLinq(list);
        }
    }

    private static void WithoutLinq(List<int> list)
    {
        foreach (var item in list)
        {
            NoOp(item);
        }
    }

    private static void WithLinq(IEnumerable<int> list) => list.ForEach(NoOp);

    private static void WithoutLinqNoGood(IEnumerable<int> enumerable)
    {
        foreach (var item in enumerable)
        {
            NoOp(item);
        }
    }
}

At a first glance, all three variants should perform equally well. However, when the ForEach extension method is called many, many times, you will end up with garbage that implies a costly GC. In fact, having this ForEach extension method on a hot path has been proven to totally kill performance in our loop-intensive application.

Similarly, the weekly typed foreach loop will also produce garbage, but it will still be faster and less memory-intensive than the ForEach extension (which also suffers from a delegate allocation).

Strongly typed foreach: Memory usage

Weekly typed foreach: Memory usage

ForEach extension: Memory usage

Analysis

For a strongly typed foreach the compiler is able to use any optimized enumerator (e.g. value based) of a class, whereas a generic ForEach extension must fall back to a generic enumerator which will be allocated on each run. Furthermore, the actual delegate will also imply an additional allocation.

You would get similar bad results with the WithoutLinqNoGood method. There, the argument is of type IEnumerable<int> instead of List<int> implying the same type of enumerator allocation.

Below are the relevant differences in IL. A value based enumerator is certainly preferable!

IL_0001:  callvirt   instance class
          [mscorlib]System.Collections.Generic.IEnumerator`1<!0> 
          class [mscorlib]System.Collections.Generic.IEnumerable`1<!!T>::GetEnumerator()

vs

IL_0001:  callvirt   instance valuetype
          [mscorlib]System.Collections.Generic.List`1/Enumerator<!0>
          class [mscorlib]System.Collections.Generic.List`1<int32>::GetEnumerator()

Conclusion

The OP asked how to call ForEach() on an IEnumerable<T>. The original answer clearly shows how it can be done. Sure you can do it, but then again; my answer clearly shows that you shouldn't.

Verified the same behavior when targeting .NET Core 3.1.401 (compiling with Visual Studio 16.7.2).

By catching Throwable it includes things that subclass Error. You should generally not do that, except perhaps at the very highest "catch all" level of a thread where you want to log or otherwise handle absolutely everything that can go wrong. It would be more typical in a framework type application (for example an application server or a testing framework) where it can be running unknown code and should not be affected by anything that goes wrong with that code, as much as possible.

"Cannot invoke an expression whose type lacks a call signature."

In your code :

class Post extends Component {
  public toggleBody: string;

  constructor() {
    this.toggleBody = this.setProp('showFullBody');
  }

  public showMore(): boolean {
    return this.toggleBody(true);
  }

  public showLess(): boolean {
    return this.toggleBody(false);
  }
}

You have public toggleBody: string;. You cannot call a string as a function. Hence errors on : this.toggleBody(true); and this.toggleBody(false);

JPA was designed to provide an automatic mapping between Objects and a relational database. Since Integer is not a persistant entity, why do you need to use JPA ? A simple JDBC request will work fine.

The Basics:

String is an immutable class, it can't be changed. StringBuilder is a mutable class that can be appended to, characters replaced or removed and ultimately converted to a String StringBuffer is the original synchronized version of StringBuilder

You should prefer StringBuilder in all cases where you have only a single thread accessing your object.

The Details:

Also note that StringBuilder/Buffers aren't magic, they just use an Array as a backing object and that Array has to be re-allocated when ever it gets full. Be sure and create your StringBuilder/Buffer objects large enough originally where they don't have to be constantly re-sized every time .append() gets called.

The re-sizing can get very degenerate. It basically re-sizes the backing Array to 2 times its current size every time it needs to be expanded. This can result in large amounts of RAM getting allocated and not used when StringBuilder/Buffer classes start to grow large.

In Java String x = "A" + "B"; uses a StringBuilder behind the scenes. So for simple cases there is no benefit of declaring your own. But if you are building String objects that are large, say less than 4k, then declaring StringBuilder sb = StringBuilder(4096); is much more efficient than concatenation or using the default constructor which is only 16 characters. If your String is going to be less than 10k then initialize it with the constructor to 10k to be safe. But if it is initialize to 10k then you write 1 character more than 10k, it will get re-allocated and copied to a 20k array. So initializing high is better than to low.

In the auto re-size case, at the 17th character the backing Array gets re-allocated and copied to 32 characters, at the 33th character this happens again and you get to re-allocated and copy the Array into 64 characters. You can see how this degenerates to lots of re-allocations and copies which is what you really are trying to avoid using StringBuilder/Buffer in the first place.

This is from the JDK 6 Source code for AbstractStringBuilder

   void expandCapacity(int minimumCapacity) {
    int newCapacity = (value.length + 1) * 2;
        if (newCapacity < 0) {
            newCapacity = Integer.MAX_VALUE;
        } else if (minimumCapacity > newCapacity) {
        newCapacity = minimumCapacity;
    }
        value = Arrays.copyOf(value, newCapacity);
    }

A best practice is to initialize the StringBuilder/Buffer a little bit larger than you think you are going to need if you don't know right off hand how big the String will be but you can guess. One allocation of slightly more memory than you need is going to be better than lots of re-allocations and copies.

Also beware of initializing a StringBuilder/Buffer with a String as that will only allocated the size of the String + 16 characters, which in most cases will just start the degenerate re-allocation and copy cycle that you are trying to avoid. The following is straight from the Java 6 source code.

public StringBuilder(String str) {
    super(str.length() + 16);
    append(str);
    }

If you by chance do end up with an instance of StringBuilder/Buffer that you didn't create and can't control the constructor that is called, there is a way to avoid the degenerate re-allocate and copy behavior. Call .ensureCapacity() with the size you want to ensure your resulting String will fit into.

The Alternatives:

Just as a note, if you are doing really heavy String building and manipulation, there is a much more performance oriented alternative called Ropes.

Another alternative, is to create a StringList implemenation by sub-classing ArrayList<String>, and adding counters to track the number of characters on every .append() and other mutation operations of the list, then override .toString() to create a StringBuilder of the exact size you need and loop through the list and build the output, you can even make that StringBuilder an instance variable and 'cache' the results of .toString() and only have to re-generate it when something changes.

Also don't forget about String.format() when building fixed formatted output, which can be optimized by the compiler as they make it better.

It works for me

.page-bg {
  background: url("res://background");
  background-position: center center;
  background-repeat: no-repeat;
  background-size: 100% 100%;
}

Simplest solution for line numbers in php storm..There are many other solutions but i think A big picture a good from 1000 words.

An hsl|a color value, set in javascript, will be instantly converted to rgb|a All you need to do then is access the computed style value

document.body.style.color = 'hsla(44, 100%, 50%, 0.8)';

console.log(window.getComputedStyle(document.body).color);

// displays: rgba(255, 187, 0, 0.8)

Technically, I guess, this isn't even any lines of code - it's just done automatically. So, depending on your environment, you might be able to get away with just this. Not that there aren't a lot of very thoughtful responses here. I don't know what your goal is.

Now, what if you want to convert from rbg|a to hsl|a?

When you have to reload the file, you can erase the value of input. Next time you add a file, 'on change' event will trigger.

document.getElementById('my_input').value = null;
// ^ that just erase the file path but do the trick

CDATA is a better general solution.

with 5 columns and colspan, this is possible (click here) (but doesn't make much sense to me):

<table width="100%" border="1" bgcolor="#ffffff">
    <colgroup>
        <col width="25%">
        <col width="25%">
        <col width="25%">
        <col width="5%">
        <col width="20%">
    </colgroup>
    <tr>
        <td>25</td>
        <td colspan="2">50</td>
        <td colspan="2">25</td>     
    </tr>
    <tr>
        <td colspan="2">50</td>
        <td colspan="2">30</td>
        <td>20</td>
    </tr>
</table>

If your image is too large (and you can't/don't want to just made the image smaller), a combination of the first two answers works great.

addButton.imageView?.contentMode = .scaleAspectFit
addButton.imageEdgeInsets = UIEdgeInsetsMake(15.0, 15.0, 15.0, 5.0)

Unless you get the image insets just right, the image will be skewed without changing the contentMode.

I tried to copy an xml file from one location to another. Here is my code:

public void SaveStockInfoToAnotherFile()
{
    string sourcePath = @"C:\inetpub\wwwroot";
    string destinationPath = @"G:\ProjectBO\ForFutureAnalysis";
    string sourceFileName = "startingStock.xml";
    string destinationFileName = DateTime.Now.ToString("yyyyMMddhhmmss") + ".xml"; // Don't mind this. I did this because I needed to name the copied files with respect to time.
    string sourceFile = System.IO.Path.Combine(sourcePath, sourceFileName);
    string destinationFile = System.IO.Path.Combine(destinationPath, destinationFileName);

    if (!System.IO.Directory.Exists(destinationPath))
       {
         System.IO.Directory.CreateDirectory(destinationPath);
       }
    System.IO.File.Copy(sourceFile, destinationFile, true);
}

Then I called this function inside a timer_elapsed function of certain interval which I think you don't need to see. It worked. Hope this helps.

You can use generated columns from MYSQL 5.7.

Example Usage:

ALTER TABLE tbl_test
ADD COLUMN calc_val INT 
GENERATED ALWAYS AS (((`column1` - 1) * 16) + `column2`) STORED;

VIRTUAL / STORED

• Virtual: calculated on the fly when a record is read from a table (default)
• Stored: calculated when a new record is inserted/updated within the table

I had to add [AllowAnonymous] to the ActionResult functions in my login page because the user was not authenticated yet.

How can I check if a value is null or empty with XSL?

For example, if categoryName is empty?

This is probably the simplest XPath expression (the one in accepted answer provides a test for the opposite, and would be longer, if negated):

not(string(categoryName))

Explanation:

The argument to the not() function above is false() exactly when there is no categoryName child ("null") of the context item, or the (single such) categoryName child has string value -- the empty string.

I'm using a when choosing construct.

For example:

<xsl:choose>
    <xsl:when test="categoryName !=null">
        <xsl:value-of select="categoryName " />
    </xsl:when>
    <xsl:otherwise>
        <xsl:value-of select="other" />
    </xsl:otherwise>
</xsl:choose>

In XSLT 2.0 use:

<xsl:copy-of select="concat(categoryName,  $vOther[not(string(current()/categoryName))])"/>

Here is a complete example:

<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
     <xsl:output omit-xml-declaration="yes" indent="yes"/>

 <xsl:variable name="vOther" select="'Other'"/>

 <xsl:template match="/">
  <xsl:copy-of select="concat(categoryName,$vOther[not(string(current()/categoryName))])"/>
 </xsl:template>
</xsl:stylesheet>

When this transformation is applied on the following XML document:

<categoryName>X</categoryName>

the wanted, correct result is produced:

X

When applied on this XML document:

<categoryName></categoryName>

or on this:

<categoryName/>

or on this

<somethingElse>Y</somethingElse>

the correct result is produced:

Other

Similarly, use this XSLT 1.0 transformation:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output omit-xml-declaration="yes" indent="yes"/>

 <xsl:variable name="vOther" select="'Other'"/>

  <xsl:template match="/">
    <xsl:copy-of select=
    "concat(categoryName,  substring($vOther, 1 div not(string(categoryName))))"/>
  </xsl:template>
</xsl:stylesheet>

Do note: No conditionals are used at all. Learn more about the importance of avoiding conditional constructs in this nice Pluralsight course:

"Tactical Design Patterns in .NET: Control Flow"

For WampServer 2.5 (Apache 2.4.9 and PHP 5.5.12):

In default I've had php_intl enabled (you can enable it when you left click on the wamp icon in the system tray > PHP > PHP extensions and check if is it marked)

To have it properly working, I've had to copy:

C:\wamp\bin\php\php5.5.12\icu**51.dll

(total 8 files)

to

C:\wamp\bin\apache\apache2.4.9\bin

Then just restart the wamp and everything was just fine.

no, you need to do something like:

$('input.sitebg').val('000000');

but you should really be using unique IDs if you can.

You can also get more specific, such as:

$('input[type=text].sitebg').val('000000');

EDIT:

do this to find your input based on the name attribute:

$('input[name=sitebg]').val('000000');

I'll add one thing: where I'm at we used to have a bunch of batch jobs that ran every night. However, we're moving away from that to using a client application scheduled in windows scheduled tasks that kicks off each job. There are (at least) three reasons for this:

1. We have some console programs that need to run every night as well. This way all scheduled tasks can be in one place. Of course, this creates a single point of failure, but if the console jobs don't run we're gonna lose a day's work the next day anyway.
2. The program that kicks off the jobs captures print messages and errors from the server and writes them to a common application log for all our batch processes. It makes logging from withing the sql jobs much simpler.
3. If we ever need to upgrade the server (and we are hoping to do this soon) we don't need to worry about moving the jobs over. Just re-point the application once.

It's a real short VB.Net app: I can post code if any one is interested.

Use $.on() to bind your chosen event to the input, don't use the shortcuts like $.keydown() etc because as of jQuery 1.7 $.on() is the preferred method to attach event handlers (see here: http://api.jquery.com/on/ and http://api.jquery.com/bind/).

$.keydown() is just a shortcut to $.bind('keydown'), and $.bind() is what $.on() replaces (among others).

To answer your question, as far as I'm aware, unless you need to fire an event on keydown specifically, the change event should do the trick for you.

$('element').on('change', function(){
    console.log('change');
});

To respond to the below comment, the javascript change event is documented here: https://developer.mozilla.org/en-US/docs/Web/Events/change

And here is a working example of the change event working on an input element, using jQuery: http://jsfiddle.net/p1m4xh08/

Regular expressions:

var numberPattern = /\d+/g;

'something102asdfkj1948948'.match( numberPattern )

This would return an Array with two elements inside, '102' and '1948948'. Operate as you wish. If it doesn't match any it will return null.

To concatenate them:

'something102asdfkj1948948'.match( numberPattern ).join('')

Assuming you're not dealing with complex decimals, this should suffice I suppose.

Import connect from react-redux and use it to connect the component with the state connect(mapStates,mapDispatch)(component)

import React from "react";
import { connect } from "react-redux";


const MyComponent = (props) => {
    return (
      <div>
        <h1>{props.title}</h1>
      </div>
    );
  }
}

Finally you need to map the states to the props to access them with this.props

const mapStateToProps = state => {
  return {
    title: state.title
  };
};
export default connect(mapStateToProps)(MyComponent);

Only the states that you map will be accessible via props

Latest and greatest way to do this:

Node supports file and buffer operations with the base64 encoding:

const fs = require('fs');
const contents = fs.readFileSync('/path/to/file.jpg', {encoding: 'base64'});

Or using the new promises API:

const fs = require('fs').promises;
const contents = await fs.readFile('/path/to/file.jpg', {encoding: 'base64'});

If you are in a browser environment you can also use btoa.

btoa is a function which takes a string as argument and produces a Base64 encoded ASCII string. Its supported by 97% of browsers.

Example:

> "Basic " + btoa("billy"+":"+"secretpassword")
< "Basic YmlsbHk6c2VjcmV0cGFzc3dvcmQ="

You can then add Basic YmlsbHk6c2VjcmV0cGFzc3dvcmQ= to the authorization header.

Note that the usual caveats about HTTP BASIC auth apply, most importantly if you do not send your traffic over https an eavesdropped can simply decode the Base64 encoded string thus obtaining your password.

This security.stackexchange.com answer gives a good overview of some of the downsides.

I wanted an utility class which is not managed by spring, so no spring annotations like @Component, @Configuration etc. But I wanted the class to read from application.properties

I managed to get it working by getting the class to be aware of the Spring Context, hence is aware of Environment, and hence environment.getProperty() works as expected.

To be explicit, I have:

application.properties

mypath=somestring

Utils.java

import org.springframework.core.env.Environment;

// No spring annotations here
public class Utils {
    public String execute(String cmd) {
        // Making the class Spring context aware
        ApplicationContextProvider appContext = new ApplicationContextProvider();
        Environment env = appContext.getApplicationContext().getEnvironment();

        // env.getProperty() works!!!
        System.out.println(env.getProperty("mypath")) 
    }
}

ApplicationContextProvider.java (see Spring get current ApplicationContext)

import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
import org.springframework.stereotype.Component;

@Component
public class ApplicationContextProvider implements ApplicationContextAware {
    private static ApplicationContext CONTEXT;

    public ApplicationContext getApplicationContext() {
        return CONTEXT;
    }

    public void setApplicationContext(ApplicationContext context) throws BeansException {
        CONTEXT = context;
    }

    public static Object getBean(String beanName) {
        return CONTEXT.getBean(beanName);
    }
}

Description

Assuming i understand your question.

You can get the selected row using the DataGridView.SelectedRows Collection. If your DataGridView allows only one selected, have a look at my sample.

DataGridView.SelectedRows Gets the collection of rows selected by the user.

Sample

if (dataGridView1.SelectedRows.Count != 0)
{
    DataGridViewRow row = this.dataGridView1.SelectedRows[0];
    row.Cells["ColumnName"].Value
}

Just an FYI, clearer, more readable syntax IMHO

"use strict";
String.prototype.pad = function( len, c, left ) {
    var s = '',
        c = ( c || ' ' ),
        len = Math.max( len, 0 ) - this.length,
        left = ( left || false );
    while( s.length < len ) { s += c };
    return ( left ? ( s + this ) : ( this + s ) );
}
Number.prototype.pad = function( len, c, left ) {
    return String( this ).pad( len, c, left );
}
Number.prototype.lZpad = function( len ) {
    return this.pad( len, '0', true );
}

This also results in less visual and readability glitches of the results than some of the other solutions, which enforce '0' as a character; answering my questions what do I do if I want to pad other characters, or on the other direction (right padding), whilst remaining easy to type, and clear to read. Pretty sure it's also the DRY'est example, with the least code for the actual leading-zero-padding function body (as the other dependent functions are largely irrelevant to the question).

The code is available for comment via gist from this github user (original source of the code) https://gist.github.com/Lewiscowles1986/86ed44f428a376eaa67f

A note on console & script testing, numeric literals seem to need parenthesis, or a variable in order to call methods, so 2.pad(...) will cause an error, whilst (2).pad(0,'#') will not. This is the same for all numbers it seems

If you are reencoding in your ffmpeg command line, that may be the reason why it is CPU intensive. You need to simply copy the streams to the single container. Since I do not have your command line I cannot suggest a specific improvement here. Your acodec and vcodec should be set to copy is all I can say.

EDIT: On seeing your command line and given you have already tried it, this is for the benefit of others who come across the same question. The command:

ffmpeg -i rtsp://@192.168.241.1:62156 -acodec copy -vcodec copy c:/abc.mp4

will not do transcoding and dump the file for you in an mp4. Of course this is assuming the streamed contents are compatible with an mp4 (which in all probability they are).

In MATLAB R2015a or newer, it is no longer necessary (or advisable from a performance standpoint) to use fspecial followed by imfilter since there is a new function called imgaussfilt that performs this operation in one step and more efficiently.

The basic syntax:

B = imgaussfilt(A,sigma) filters image A with a 2-D Gaussian smoothing kernel with standard deviation specified by sigma.

The size of the filter for a given Gaussian standard deviation (sigam) is chosen automatically, but can also be specified manually:

B = imgaussfilt(A,sigma,'FilterSize',[3 3]);

The default is 2*ceil(2*sigma)+1.

Additional features of imgaussfilter are ability to operate on gpuArrays, filtering in frequency or spacial domain, and advanced image padding options. It looks a lot like IPP... hmmm. Plus, there's a 3D version called imgaussfilt3.

Note that if you want to scroll an element instead of the full window, elements don't have the scrollTo and scrollBy methods. You should:

var el = document.getElementById("myel"); // Or whatever method to get the element

// To set the scroll
el.scrollTop = 0;
el.scrollLeft = 0;

// To increment the scroll
el.scrollTop += 100;
el.scrollLeft += 100;

You can also mimic the window.scrollTo and window.scrollBy functions to all the existant HTML elements in the webpage on browsers that don't support it natively:

Object.defineProperty(HTMLElement.prototype, "scrollTo", {
    value: function(x, y) {
        el.scrollTop = y;
        el.scrollLeft = x;
    },
    enumerable: false
});

Object.defineProperty(HTMLElement.prototype, "scrollBy", {
    value: function(x, y) {
        el.scrollTop += y;
        el.scrollLeft += x;
    },
    enumerable: false
});

so you can do:

var el = document.getElementById("myel"); // Or whatever method to get the element, again

// To set the scroll
el.scrollTo(0, 0);

// To increment the scroll
el.scrollBy(100, 100);

NOTE: Object.defineProperty is encouraged, as directly adding properties to the prototype is a breaking bad habit (When you see it :-).

From Geekpedia:

// Store integer 182
int decValue = 182;

// Convert integer 182 as a hex in a string variable
string hexValue = decValue.ToString("X");

// Convert the hex string back to the number
int decAgain = int.Parse(hexValue, System.Globalization.NumberStyles.HexNumber);

Java now has a pretty good built-in date library, java.time bundled with Java 8.

import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;

public class Foo {
    public static void main(String[] args) {

        DateTimeFormatter format =
            DateTimeFormatter.ofPattern("yyyy-MM-dd'T'HH:mm:ss'Z'");

        LocalDateTime now = LocalDateTime.now();
        LocalDateTime then = now.minusDays(7);

        System.out.println(String.format(
            "Now:  %s\nThen: %s",
            now.format(format),
            then.format(format)
        ));
        /*
            Example output:
                Now:  2014-05-09T14:51:48Z
                Then: 2014-05-02T14:51:48Z
         */
    }
}

$('#example').dataTable( {
      "createdRow": function( row, data, dataIndex ) {
        if ( data[4] == "A" ) {
          $(row).addClass( 'important' );
        }
      }
    } );

I finally figured out a how to use Maven. From within Eclipse, create a new Maven project.

Download Maven, extract the archive, add the /bin folder to path.

Validate install from command-line by running mvn -v (will print version and java install path)

Change to the project root folder (where pom.xml is located) and run:

mvn dependency:copy-dependencies

All jar-files are downloaded to /target/dependency.

To set another output directory:

mvn dependency:copy-dependencies -DoutputDirectory="c:\temp"

Now it's possible to re-use this Maven-project for all dependency downloads by altering the pom.xml

Add jars to java project by build path -> configure build path -> libraries -> add JARs..

sometimes the error depends on the actual cause. we had a case where mysql-python was installed through the python-mysqldb debian package.

a developer who didn't know this, accidentally ran pip uninstall mysql-python and then failed to recover with pip install mysql-python giving the above error.

pip uninstall mysql-python had destroyed the debian package contents, and of course pip install mysql-python failed because the debian package didn't need any dev files.

the correct solution in that case was apt-get install --reinstall python-mysqldb which restored mysql-python to its original state.

SQL Server ignores trailing whitespace when comparing strings, so ' ' = ''. Just use the following query for your update

UPDATE table
SET col1 = NULL
WHERE col1 = ''

NULL values in your table will stay NULL, and col1s with any number on space only characters will be changed to NULL.

If you want to do it during your copy from one table to another, use this:

INSERT INTO newtable ( col1, othercolumn )
SELECT
   NULLIF(col1, ''),
   othercolumn
FROM table

No, goto is not used, but you can define labels and leave a loop up to the label. You can use break or continue followed by the label. So you can jump out more than one loop level. Have a look at the tutorial.

There are lot of factors , first see whether server returns the result, then check between server and client.

rectify them from server side first,then check the writing condition between server and client !

server side rectify the time outs between the datalayer and server from client side rectify the time out and number of available connections !

Try this to Convert from Decimal to Hex

Thanks to G_money and other suggestions for this excellent solution to input-text with inline dropdown... here's another great solution.

<form class="form-inline" role="form" id="yourformID-form" action="" method="post">
    <div class="input-group">
        <span class="input-group-addon"><i class="fa fa-male"></i></span>

        <div class="form-group">
            <input size="50" maxlength="50" class="form-control" name="q" type="text">          
        </div>

        <div class="form-group">
            <select class="form-control" name="category">
                <option value=""></option>
                <option value="0">select1</option>
                <option value="1">select2</option>
                <option value="2">select3</option>
            </select>           
        </div>
    </div>
</form>

This works with Bootstrap 3: allowing input-text inline with a select dropdown. Here's what it looks like below...

controller class is not working any functions.

so I recommend to you use the following scripts

global $argv;

if(is_array($argv)){
    $action = $argv[1];
    $method = $argv[2];
}else{
    $request_uri = $_SERVER['REQUEST_URI'];
    $pattern = "/.*?\/index\.php\/(.*?)\/(.*?)$/";
    preg_match($pattern, $request_uri, $params);
    $action = $params[1];
    $method = $params[2];
}

The following line doesn't work?

rm -rf ~/anaconda3 

You should know where your anaconda3(or anaconda1, anaconda2) is installed. So write

which anaconda

output

output: somewhere

Now use that somewhere and run:

rm -rf somewhere 

Cache: This is a place acquired by kernel on physical RAM to store pages in caches. Now we need some sort of index to get the address of pages from caches. Here we need the buffer for page caches which keeps metadata of page cache.

TL;DR

Yes, it is. There are better ways to bootstrap Hibernate, like the following ones.

Hibernate-native bootstrap

The legacy Configuration object is less powerful than using the BootstrapServiceRegistryBuilder, introduced since Hibernate 4:

final BootstrapServiceRegistryBuilder bsrb = new BootstrapServiceRegistryBuilder()
    .enableAutoClose();

Integrator integrator = integrator();
if (integrator != null) {
    bsrb.applyIntegrator( integrator );
}

final BootstrapServiceRegistry bsr = bsrb.build();

final StandardServiceRegistry serviceRegistry = 
    new StandardServiceRegistryBuilder(bsr)
        .applySettings(properties())
        .build();

final MetadataSources metadataSources = new MetadataSources(serviceRegistry);

for (Class annotatedClass : entities()) {
    metadataSources.addAnnotatedClass(annotatedClass);
}

String[] packages = packages();
if (packages != null) {
    for (String annotatedPackage : packages) {
        metadataSources.addPackage(annotatedPackage);
    }
}

String[] resources = resources();
if (resources != null) {
    for (String resource : resources) {
        metadataSources.addResource(resource);
    }
}

final MetadataBuilder metadataBuilder = metadataSources.getMetadataBuilder()
    .enableNewIdentifierGeneratorSupport(true)
    .applyImplicitNamingStrategy(ImplicitNamingStrategyLegacyJpaImpl.INSTANCE);

final List<Type> additionalTypes = additionalTypes();
if (additionalTypes != null) {
    additionalTypes.stream().forEach(type -> {
        metadataBuilder.applyTypes((typeContributions, sr) -> {
            if(type instanceof BasicType) {
                typeContributions.contributeType((BasicType) type);
            } else if (type instanceof UserType ){
                typeContributions.contributeType((UserType) type);
            } else if (type instanceof CompositeUserType) {
                typeContributions.contributeType((CompositeUserType) type);
            }
        });
    });
}

additionalMetadata(metadataBuilder);

MetadataImplementor metadata = (MetadataImplementor) metadataBuilder.build();

final SessionFactoryBuilder sfb = metadata.getSessionFactoryBuilder();
Interceptor interceptor = interceptor();
if(interceptor != null) {
    sfb.applyInterceptor(interceptor);
}

SessionFactory sessionFactory = sfb.build();

JPA bootstrap

You can also bootstrap Hibernate using JPA:

PersistenceUnitInfo persistenceUnitInfo = persistenceUnitInfo(getClass().getSimpleName());
Map configuration = properties();

Interceptor interceptor = interceptor();
if (interceptor != null) {
    configuration.put(AvailableSettings.INTERCEPTOR, interceptor);
}

Integrator integrator = integrator();
if (integrator != null) {
    configuration.put(
        "hibernate.integrator_provider", 
        (IntegratorProvider) () -> Collections.singletonList(integrator));
}

EntityManagerFactoryBuilderImpl entityManagerFactoryBuilder = 
    new EntityManagerFactoryBuilderImpl(
        new PersistenceUnitInfoDescriptor(persistenceUnitInfo), 
        configuration
);
EntityManagerFactory entityManagerFactory = entityManagerFactoryBuilder.build();

This way, you are building the EntityManagerFactory instead of a SessionFactory. However, the SessionFactory extends the EntityManagerFactory, so the actual object that's built is aSessionFactoryImpl` too.

Conclusion

These two bootstrapping methods affect Hibernate behavior. When using the native bootstrap, Hibernate behaves in the legacy mode, which predates JPA.

When bootstrapping using JPA, Hibernate will behave according to the JPA specification.

There are several differences between these two modes:

• How the AUTO flush mode works in regards to native SQL queries
• How the entity Proxy is built. Traditionally, Hibernate did not hit the DB when building a Proxy, but JPA requires throwing an EntityNotFoundException, therefore demanding a DB check.
• whether you can delete a non-managed entity

For more details about these differences, check out the JpaCompliance class.

Try something like grep -r -n -i --include="*.html *.php *.js" searchstrinhere .

the -i makes it case insensitlve

the . at the end means you want to start from your current directory, this could be substituted with any directory.

the -r means do this recursively, right down the directory tree

the -n prints the line number for matches.

the --include lets you add file names, extensions. Wildcards accepted

Clickatell is a popular SMS gateway. It works in 200+ countries.

Their API offers a choice of connection options via: HTTP/S, SMPP, SMTP, FTP, XML, SOAP. Any of these options can be used from php.

The HTTP/S method is as simple as this:

http://api.clickatell.com/http/sendmsg?to=NUMBER&msg=Message+Body+Here

The SMTP method consists of sending a plain-text e-mail to: [email protected], with the following body:

user: xxxxx
password: xxxxx
api_id: xxxxx
to: 448311234567
text: Meet me at home

You can also test the gateway (incoming and outgoing) for free from your browser

Well, goto, but that is ugly, and not always possible. You can also place the loops into a method (or an anon-method) and use return to exit back to the main code.

    // goto
    for (int i = 0; i < 100; i++)
    {
        for (int j = 0; j < 100; j++)
        {
            goto Foo; // yeuck!
        }
    }
Foo:
    Console.WriteLine("Hi");

vs:

// anon-method
Action work = delegate
{
    for (int x = 0; x < 100; x++)
    {
        for (int y = 0; y < 100; y++)
        {
            return; // exits anon-method
        }
    }
};
work(); // execute anon-method
Console.WriteLine("Hi");

Note that in C# 7 we should get "local functions", which (syntax tbd etc) means it should work something like:

// local function (declared **inside** another method)
void Work()
{
    for (int x = 0; x < 100; x++)
    {
        for (int y = 0; y < 100; y++)
        {
            return; // exits local function
        }
    }
};
Work(); // execute local function
Console.WriteLine("Hi");

I am adding this, in addition to other solutions.

with Java 10, to get process id

final RuntimeMXBean runtime = ManagementFactory.getRuntimeMXBean();
final long pid = runtime.getPid();

XAML :

<DataGrid x:Name="dgv_Students" AutoGenerateColumns="False"  ItemsSource="{Binding People}" Margin="10,20,10,0" Style="{StaticResource AzureDataGrid}" FontFamily="B Yekan" Background="#FFB9D1BA" >
                <DataGrid.Columns>
                    <DataGridTemplateColumn>
                        <DataGridTemplateColumn.CellTemplate>
                            <DataTemplate>
                                <Button Click="Button_Click_dgvs">Text</Button>
                            </DataTemplate>
                        </DataGridTemplateColumn.CellTemplate>
                    </DataGridTemplateColumn>
                    </DataGrid.Columns>

Code Behind :

       private IEnumerable<DataGridRow> GetDataGridRowsForButtons(DataGrid grid)
{ //IQueryable 
    var itemsSource = grid.ItemsSource as IEnumerable;
    if (null == itemsSource) yield return null;
    foreach (var item in itemsSource)
    {
        var row = grid.ItemContainerGenerator.ContainerFromItem(item) as DataGridRow;
        if (null != row & row.IsSelected) yield return row;
    }
}

void Button_Click_dgvs(object sender, RoutedEventArgs e)
{

    for (var vis = sender as Visual; vis != null; vis = VisualTreeHelper.GetParent(vis) as Visual)
        if (vis is DataGridRow)
        {
           // var row = (DataGrid)vis;

            var rows = GetDataGridRowsForButtons(dgv_Students);
            string id;
            foreach (DataGridRow dr in rows)
            {
                id = (dr.Item as tbl_student).Identification_code;
                MessageBox.Show(id);
                 break;
            }
            break;
        }
}

After clicking on the Button, the ID of that row is returned to you and you can use it for your Button name.

I believe the cleanest way to strip a single character from a string with bash is:

echo ${COMPANY_NAME:: -1}

but I haven't been able to embed the grep piece within the curly braces, so your particular task becomes a two-liner:

COMPANY_NAME=$(grep "company_name" file.txt); COMPANY_NAME=${COMPANY_NAME:: -1} 

This will strip any character, semicolon or not, but can get rid of the semicolon specifically, too. To remove ALL semicolons, wherever they may fall:

echo ${COMPANY_NAME/;/}

To remove only a semicolon at the end:

echo ${COMPANY_NAME%;}

Or, to remove multiple semicolons from the end:

echo ${COMPANY_NAME%%;}

If you came here from google because tab isnt indenting, this can also be because "Tab Moves Focus" is on. It is at the bottom right, and if you have a large enough monitor you may miss it despite it being highlighted.

Click the Green area or Ctrl + M to make it stop. I'm not sure it can be disabled entirely, then again I dont know why a code editor would want to mess with something like indenting.

I've been burned for broadcasting these opinions in public before, but here goes:

Well-written code in dynamically typed languages follows static-typing conventions

Having used Python, PHP, Perl, and a few other dynamically typed languages, I find that well-written code in these languages follows static typing conventions, for example:

• Its considered bad style to re-use a variable with different types (for example, its bad style to take a list variable and assign an int, then assign the variable a bool in the same method). Well-written code in dynamically typed languages doesn't mix types.

• A type-error in a statically typed language is still a type-error in a dynamically typed language.

• Functions are generally designed to operate on a single datatype at a time, so that a function which accepts a parameter of type T can only sensibly be used with objects of type T or subclasses of T.

• Functions designed to operator on many different datatypes are written in a way that constrains parameters to a well-defined interface. In general terms, if two objects of types A and B perform a similar function, but aren't subclasses of one another, then they almost certainly implement the same interface.

While dynamically typed languages certainly provide more than one way to crack a nut, most well-written, idiomatic code in these languages pays close attention to types just as rigorously as code written in statically typed languages.

Dynamic typing does not reduce the amount of code programmers need to write

When I point out how peculiar it is that so many static-typing conventions cross over into dynamic typing world, I usually add "so why use dynamically typed languages to begin with?". The immediate response is something along the lines of being able to write more terse, expressive code, because dynamic typing allows programmers to omit type annotations and explicitly defined interfaces. However, I think the most popular statically typed languages, such as C#, Java, and Delphi, are bulky by design, not as a result of their type systems.

I like to use languages with a real type system like OCaml, which is not only statically typed, but its type inference and structural typing allow programmers to omit most type annotations and interface definitions.

The existence of the ML family of languages demostrates that we can enjoy the benefits of static typing with all the brevity of writing in a dynamically typed language. I actually use OCaml's REPL for ad hoc, throwaway scripts in exactly the same way everyone else uses Perl or Python as a scripting language.

The first argument is the file you wish to execute, and the second argument is an array of null-terminated strings that represent the appropriate arguments to the file as specified in the man page.

For example:

char *cmd = "ls";
char *argv[3];
argv[0] = "ls";
argv[1] = "-la";
argv[2] = NULL;

execvp(cmd, argv); //This will run "ls -la" as if it were a command

Put them inside btn-toolbar or some other container, not btn-group. btn-group joins them together. More info on Bootstrap documentation.

Edit: The original question was for Bootstrap 2.x, but the same is still valid for Bootstrap 3 and Bootstrap 4.

In Bootstrap 4 you will need to add appropriate margin to your groups using utility classes, such as mx-2.

I solved this problem by first verifying the that remote did not have anything checked out (it really was not supposed to), and then made it bare with:

$ git config --bool core.bare true

After that git push worked fine.

Things have changed a little in the way Charles provides HTTPS proxying.

First the certificates installation options have been moved to the help menu.

Help -> SSL Proxying -> Install Charles Root Certificate
Help -> SSL Proxying -> Install Charles Root Certificate in iOS Simulators

Second, starting in iOS 9 you must provide a NSAppTransportSecurity option in your Info.plist and if you want Charles to work properly as a man in the middle, you must add:

<key>NSTemporaryExceptionAllowsInsecureHTTPLoads</key>
<true/>

as part of the your domains see full example:

<key>NSExceptionDomains</key>
    <dict>
        <key>yourdomain.com</key>
        <dict>
            <key>NSIncludesSubdomains</key>
            <true/>
            <key>NSTemporaryExceptionAllowsInsecureHTTPLoads</key>
            <true/>
            <key>NSTemporaryExceptionMinimumTLSVersion</key>
            <string>TLSv1.1</string>
        </dict>

The reason being (I guess) that Charles at some point communicates in clear http after acting as the man in the middle https server.

Last step is to activate SSL Proxying for this domain in Charles (right click on domain and select Enable SSL Proxying)

I think the implement should be easy, but considering about the efficiency, you should use LinkedList but not ArrayList as the container. You can refer to the following code:

import java.util.LinkedList;
import java.util.List;

public class DataContainer {

    private List<Integer> list;

    int length = 10;
    public void addDataToArrayList(int data){
        list.add(0, data);
        if(list.size()>10){
            list.remove(length);
        }
    }

    public static void main(String[] args) {
        DataContainer comp = new DataContainer();
        comp.list = new LinkedList<Integer>();

        int cycleCount = 100000000;

        for(int i = 0; i < cycleCount; i ++){
            comp.addDataToArrayList(i);
        }
    }
}

You need to use regular expressions in your custom validator. For example, here's the code that allows only 9 digits in the input fields:

function ssnValidator(control: FormControl): {[key: string]: any} {
  const value: string = control.value || '';
  const valid = value.match(/^\d{9}$/);
  return valid ? null : {ssn: true};
}

Take a look at a sample app here:

https://github.com/Farata/angular2typescript/tree/master/Angular4/form-samples/src/app/reactive-validator

All user installed apks are located in /data/app/, but you can only access this if you are rooted(afaik, you can try without root and if it doesn't work, rooting isn't hard. I suggest you search xda-developers for rooting instructions)

Use Root explorer or ES File Explorer to access /data/app/ (you have to keep going "up" until you reach the root directory /, kind of like C: in windows, before you can see the data directory(folder)). In ES file explorer you must also tick a checkbox in settings to allow going up to the root directory.

When you are in there you will see all your applications apks, though they might be named strangely. Just copy the wanted .apk and paste in the sd card, after that you can copy it to your computer and when you want to install it just open the .apk in a file manager (be sure to have install from unknown sources enabled in android settings). Even if you only want to send over bluetooth I would recommend copying it to the SD first.

PS Note that paid apps probably won't work being copied this way, since they usually check their licence online. PPS Installing an app this way may not link it with google play(you won't see it in my apps and it won't get updates).

According to Microsoft docs:

the read-first approach requires an extra database read, and can result in more complex code for handling concurrency conflict

However, you should know that using Update method on DbContext will mark all the fields as modified and will include all of them in the query. If you want to update a subset of fields you should use the Attach method and then mark the desired field as modified manually.

context.Attach(person);
context.Entry(person).Property(p => p.Name).IsModified = true;
context.SaveChanges();

Update

I typically used docker attach to see what STDOUT was displaying, for troubleshooting containers. I just found docker logs --follow 621a4334f97b, which lets me see the STDOUT whilst also being able to ctrl+c off of it without affecting container operation! Exactly what I've always wanted.

... naturally you'll need to substitue in your own container ID.

Original Answer

I wanted to leave the container running, but had attached without starting the container with -it. My solution was to sacrifice my SSH connection instead (since I was SSHed into the machine that was running the containers). Killing that ssh session left the container intact but detached me from it.

How to tell if an object is a unicode string or a byte string

You can use type or isinstance.

In Python 2:

>>> type(u'abc')  # Python 2 unicode string literal
<type 'unicode'>
>>> type('abc')   # Python 2 byte string literal
<type 'str'>

In Python 2, str is just a sequence of bytes. Python doesn't know what its encoding is. The unicode type is the safer way to store text. If you want to understand this more, I recommend http://farmdev.com/talks/unicode/.

In Python 3:

>>> type('abc')   # Python 3 unicode string literal
<class 'str'>
>>> type(b'abc')  # Python 3 byte string literal
<class 'bytes'>

In Python 3, str is like Python 2's unicode, and is used to store text. What was called str in Python 2 is called bytes in Python 3.

How to tell if a byte string is valid utf-8 or ascii

You can call decode. If it raises a UnicodeDecodeError exception, it wasn't valid.

>>> u_umlaut = b'\xc3\x9c'   # UTF-8 representation of the letter 'Ü'
>>> u_umlaut.decode('utf-8')
u'\xdc'
>>> u_umlaut.decode('ascii')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 0: ordinal not in range(128)

The answers given so far are not ideal because they require a lot of needless work resolving merge conflicts, or they make too many assumptions which are frequently false. This is how to do it perfectly. The link is to my own site.

How to Commit to a Different Branch in git

You have uncommited changes on my_branch that you want to commit to master, without committing all the changes from my_branch.

Example

git merge master
git stash -u
git checkout master
git stash apply
git reset
git add example.js
git commit
git checkout .
git clean -f -d
git checkout my_branch
git merge master
git stash pop

Explanation

Start by merging master into your branch, since you'll have to do that eventually anyway, and now is the best time to resolve any conflicts.

The -u option (aka --include-untracked) in git stash -u prevents you from losing untracked files when you later do git clean -f -d within master.

After git checkout master it is important that you do NOT git stash pop, because you will need this stash later. If you pop the stash created in my_branch and then do git stash in master, you will cause needless merge conflicts when you later apply that stash in my_branch.

git reset unstages everything resulting from git stash apply. For example, files that have been modified in the stash but do not exist in master get staged as "deleted by us" conflicts.

git checkout . and git clean -f -d discard everything that isn't committed: all changes to tracked files, and all untracked files and directories. They are already saved in the stash and if left in master would cause needless merge conflicts when switching back to my_branch.

The last git stash pop will be based on the original my_branch, and so will not cause any merge conflicts. However, if your stash contains untracked files which you have committed to master, git will complain that it "Could not restore untracked files from stash". To resolve this conflict, delete those files from your working tree, then git stash pop, git add ., and git reset.

I think it's worth answering the generic question "R - test if string contains string" here.

For that, use the grep function.

# example:
> if(length(grep("ab","aacd"))>0) print("found") else print("Not found")
[1] "Not found"
> if(length(grep("ab","abcd"))>0) print("found") else print("Not found")
[1] "found"

I had a similar problem with robotjs. There were some deprecated code that required node v11, but I had already compiled electron code on v12. So I got basically the same error. Nothing here worked as I was basically trying to rebuild electron and my other dependencies into node v11 from v12.

Here is what I did (part of this is based on chitzui's answer, credit where credit is due):

• Back up package.json
• completely delete the node_modules folder
• completely delete package_lock.json
• delete package.json (will reinit later)
• Close any open editors and other cmd windows that are in the project's directory.
• run npm init to reinit package, then missing data with old backed up package.json
• run npm i
• fixed :)

Hope this helps.

There is no syntax for block quote in VBA. The work around is to use the button to quickly block or unblock multiple lines of code.

To create an empty vector use:

vec <- c();

Please note, I am not making any assumptions about the type of vector you require, e.g. numeric.

Once the vector has been created you can add elements to it as follows:

For example, to add the numeric value 1:

vec <- c(vec, 1);

or, to add a string value "a"

vec <- c(vec, "a");

In my case I had an async void Method and I replaced with async Task ,so the test run as i expected :

    [TestMethod]
    public async  void SendTest(){}

replace with :

    [TestMethod]
    public async  Task SendTest(){}

It's simple using a table:

<html>

<head>
    <title>100% Height test</title>
</head>

<body>
    <table style="float: left; height: 100%; width: 200px; border: 1px solid red">
        <tbody>
            <tr>
                <td>Nav area</td>
            </tr>
        </tbody>
    </table>
    <div style="border: 1px solid green;">Content blabla... text
        <br /> text
        <br /> text
        <br /> text
        <br />
    </div>
</body>

</html>

When DIV was introduced, people were so afraid of tables that the poor DIV became the metaphorical hammer.

Adding a bit to use Gokhan's solution for using:

--allow-file-access-from-files

Now you just need to append above text in Target text followed by a space. make sure you close all the instances of chrome browser after adding above property. Now restart chrome by the icon where you added this property. It should work for all.

Here's what we do:

• Create a new connection, set the name, IP address and the appropriate port:

  

• Set up authentication, if required

  

• Optionally set up other available settings for SSL, SSH, etc.

• Save and connect

$keys = array_keys($arr);
$keys = rsort($keys);

print $keys[0];

should print "10"

$anchorScroll is indeed the answer to this, but there's a much better way to use it in more recent versions of Angular.

Now, $anchorScroll accepts the hash as an optional argument, so you don't have to change $location.hash at all. (documentation)

This is the best solution because it doesn't affect the route at all. I couldn't get any of the other solutions to work because I'm using ngRoute and the route would reload as soon as I set $location.hash(id), before $anchorScroll could do its magic.

Here is how to use it... first, in the directive or controller:

$scope.scrollTo = function (id) {
  $anchorScroll(id);  
}

and then in the view:

<a href="" ng-click="scrollTo(id)">Text</a>

Also, if you need to account for a fixed navbar (or other UI), you can set the offset for $anchorScroll like this (in the main module's run function):

  .run(function ($anchorScroll) {
      //this will make anchorScroll scroll to the div minus 50px
      $anchorScroll.yOffset = 50;
  });

router.route('/product/name/:name')
.get(function(req, res) {

    var regex = new RegExp(req.params.name, "i")
    ,   query = { description: regex };

    Product.find(query, function(err, products) {
        if (err) {
            res.json(err);
        }

        res.json(products);
    });

});  

I didn't have a package.json. Make sure you have one.

The question mark is the conditional operator. The code means that if f==r then 1 is returned, otherwise, return 0. The code could be rewritten as

int qempty()
{
  if(f==r)
    return 1;
  else
    return 0;
}

which is probably not the cleanest way to do it, but hopefully helps your understanding.

Use the zip method in Python. This function returns a list of tuples, where the i-th tuple contains the i-th element from each of the argument sequences or iterables

    while running:
        for thiselem,nextelem in zip(li, li[1 : ] + li[ : 1]):
            #Do whatever you want with thiselem and nextelem         

In addition to the answer, you can't directly use output redirection operators in the set part of for loop (e.g. if you wanna hide stderror output from a user and provide a nicer error message). Instead, you have to escape them with a caret character (^):

for /f %%O in ('some-erroring-command 2^> nul') do (echo %%O)

Reference: Redirect output of command in for loop of batch script

Try the following:

PreparedStatementCreator creator = new PreparedStatementCreator() {
    @Override
    public PreparedStatement createPreparedStatement(Connection con) throws SQLException {
        PreparedStatement updateSales = con.prepareStatement(
        "UPDATE COFFEES SET SALES = ? WHERE COF_NAME LIKE ? ");
        updateSales.setInt(1, 75); 
        updateSales.setString(2, "Colombian"); 
        return updateSales;
    }
};

Create a new 640x480 image and fill it with purple (red+blue):

cv::Mat mat(480, 640, CV_8UC3, cv::Scalar(255,0,255));

Note:

• height before width
• type CV_8UC3 means 8-bit unsigned int, 3 channels
• colour format is BGR

In addition to answer of @jww, I would like to say that the configuration in openssl-ca.cnf,

default_days     = 1000         # How long to certify for

defines the default number of days the certificate signed by this root-ca will be valid. To set the validity of root-ca itself you should use '-days n' option in:

openssl req -x509 -days 3000 -config openssl-ca.cnf -newkey rsa:4096 -sha256 -nodes -out cacert.pem -outform PEM

Failing to do so, your root-ca will be valid for only the default one month and any certificate signed by this root CA will also have validity of one month.

PyPDF2 in some cases ignores the white spaces and makes the result text a mess, but I use PyMuPDF and I'm really satisfied you can use this link for more info

Doing it in one bulk read:

import re

textfile = open(filename, 'r')
filetext = textfile.read()
textfile.close()
matches = re.findall("(<(\d{4,5})>)?", filetext)

Line by line:

import re

textfile = open(filename, 'r')
matches = []
reg = re.compile("(<(\d{4,5})>)?")
for line in textfile:
    matches += reg.findall(line)
textfile.close()

But again, the matches that returns will not be useful for anything except counting unless you added an offset counter:

import re

textfile = open(filename, 'r')
matches = []
offset = 0
reg = re.compile("(<(\d{4,5})>)?")
for line in textfile:
    matches += [(reg.findall(line),offset)]
    offset += len(line)
textfile.close()

But it still just makes more sense to read the whole file in at once.

Check out commons math from apache. There is quite a lot there.

I couldn't get the compiler (x64 version) to use the sysroot until I added SET(CMAKE_SYSROOT $ENV{HOME}/raspberrypi/rootfs) to pi.cmake.

I just leave it there. If someone will still need it, then you can use this:

template <class T>
bool isString(T* t) { return false;  } // normal case returns false

template <>
bool isString(char* t) { return true; }  // but for char* or String.c_str() returns true
.
.
.

This will only CHECK type not GET it and only for 1 type or 2.

Bootstrap 3 now has Responsive tables out of the box. Hooray! :)

You can check it here: https://getbootstrap.com/docs/3.3/css/#tables-responsive

Add a <div class="table-responsive"> surrounding your table and you should be good to go:

<div class="table-responsive">
  <table class="table">
    ...
  </table>
</div>

To make it work on all layouts you can do this:

.table-responsive
{
    overflow-x: auto;
}

If you have installed Visual studio 2017 (profressional)

The install location:

C:\ProgramData\Anaconda3\Scripts

If you do not want the hassle of putting this in your path environment variable on windows and restarting you can run it by simply:

C:\>"C:\ProgramData\Anaconda3\Scripts\conda.exe" update qt pyqt

I had the same problem and when I checked the properties of the file on file explorer, it shows me the next message:

"Security: This file came from another computer and might be blocked to help protect this computer"

You click on the "Unblock" button and... you can access to the file from R without any problem, just using read.csv() function and from the directory specified as your working directory, even if is not the same as the file’s directory you are accessing to.

1. Launch MySQL Workbench.
2. On the left pane of the welcome window, choose a database to connect to under "Open Connection to Start Querying".
3. The query window will open. On its left pane, there is a section titled "Object Browser", which shows the list of databases. (Side note: The terms "schema" and "database" are synonymous in this program.)
4. Right-click on one of the existing databases and click "Create Schema...". This will launch a wizard that will help you create a database.

If you'd prefer to do it in SQL, enter this query into the query window:

CREATE SCHEMA Test

Press CTRL + Enter to submit it, and you should see confirmation in the output pane underneath the query window. You'll have to right-click on an existing schema in the Object panel and click "Refresh All" to see it show up, though.

Swift 4/5

Another way to achieve this is with the filter function

var elements = [1,2,3,4,5]
if let object = elements.filter({ $0 == 5 }).first {
    print("found")
} else {
    print("not found")
}

According to Listening For and Broadcasting Global Messages, and Setting Alarms in Common Tasks and How to Do Them in Android:

If the receiving class is not registered using in its manifest, you can dynamically instantiate and register a receiver by calling Context.registerReceiver().

Take a look at registerReceiver (BroadcastReceiver receiver, IntentFilter filter) for more info.

C++11 has another (imperfect) option:

std::array<int, 100> a;
a.fill(-1);

I think use drop duplicate sometimes will not so useful depending dataframe.

I found this:

[in] df['col_1'].unique()
[out] array(['A', 'B', 'C'], dtype=object)

And work for me!

https://riptutorial.com/pandas/example/26077/select-distinct-rows-across-dataframe

I believe you can just use array_key_exists nowadays:

<?php
$a=array("Mac"=>"NT","Irix"=>"Linux");
if (array_key_exists("Mac",$a))
  {
  echo "Key exists!";
  }
else
  {
  echo "Key does not exist!";
  }
?>

There is a circumstance where you're required to declare it final --otherwise it will result in compile error--, namely passing them through into anonymous classes. Basic example:

public FileFilter createFileExtensionFilter(final String extension) {
    FileFilter fileFilter = new FileFilter() {
        public boolean accept(File pathname) {
            return pathname.getName().endsWith(extension);
        }
    };

    // What would happen when it's allowed to change extension here?
    // extension = "foo";

    return fileFilter;
}

Removing the final modifier would result in compile error, because it isn't guaranteed anymore that the value is a runtime constant. Changing the value from outside the anonymous class would namely cause the anonymous class instance to behave different after the moment of creation.

I have achieved this by using one nice example i have found here. I have replaced the jquery dialog used in that example with the Twitter Bootstrap Modal windows.

PHP’s mysql_real_escape_string function is only a wrapper for MySQL’s mysql_real_escape_string function. It basically prepares the input string to be safely used in a MySQL string declaration by escaping certain characters so that they can’t be misinterpreted as a string delimiter or an escape sequence delimiter and thereby allow certain injection attacks.

The real in mysql_real_escape_string in opposite to mysql_escape_string is due to the fact that it also takes the current character encoding into account as the risky characters are not encoded equally in the different character encodings. But you need to specify the character encoding change properly in order to get mysql_real_escape_string work properly.

The comma separated list option is the easiest but becomes challenging if the values could include commas.

Here is an example of the a.1, a.2, ... approach:

for (String value : getPropertyList(prop, "a"))
{
    System.out.println(value);
}

public static List<String> getPropertyList(Properties properties, String name) 
{
    List<String> result = new ArrayList<String>();
    for (Map.Entry<Object, Object> entry : properties.entrySet())
    {
        if (((String)entry.getKey()).matches("^" + Pattern.quote(name) + "\\.\\d+$"))
        {
            result.add((String) entry.getValue());
        }
    }
    return result;
}

unicode_escape doesn't work in general

It turns out that the string_escape or unicode_escape solution does not work in general -- particularly, it doesn't work in the presence of actual Unicode.

If you can be sure that every non-ASCII character will be escaped (and remember, anything beyond the first 128 characters is non-ASCII), unicode_escape will do the right thing for you. But if there are any literal non-ASCII characters already in your string, things will go wrong.

unicode_escape is fundamentally designed to convert bytes into Unicode text. But in many places -- for example, Python source code -- the source data is already Unicode text.

The only way this can work correctly is if you encode the text into bytes first. UTF-8 is the sensible encoding for all text, so that should work, right?

The following examples are in Python 3, so that the string literals are cleaner, but the same problem exists with slightly different manifestations on both Python 2 and 3.

>>> s = 'naïve \\t test'
>>> print(s.encode('utf-8').decode('unicode_escape'))
naïve   test

Well, that's wrong.

The new recommended way to use codecs that decode text into text is to call codecs.decode directly. Does that help?

>>> import codecs
>>> print(codecs.decode(s, 'unicode_escape'))
naïve   test

Not at all. (Also, the above is a UnicodeError on Python 2.)

The unicode_escape codec, despite its name, turns out to assume that all non-ASCII bytes are in the Latin-1 (ISO-8859-1) encoding. So you would have to do it like this:

>>> print(s.encode('latin-1').decode('unicode_escape'))
naïve    test

But that's terrible. This limits you to the 256 Latin-1 characters, as if Unicode had never been invented at all!

>>> print('Erno \\t Rubik'.encode('latin-1').decode('unicode_escape'))
UnicodeEncodeError: 'latin-1' codec can't encode character '\u0151'
in position 3: ordinal not in range(256)

Adding a regular expression to solve the problem

(Surprisingly, we do not now have two problems.)

What we need to do is only apply the unicode_escape decoder to things that we are certain to be ASCII text. In particular, we can make sure only to apply it to valid Python escape sequences, which are guaranteed to be ASCII text.

The plan is, we'll find escape sequences using a regular expression, and use a function as the argument to re.sub to replace them with their unescaped value.

import re
import codecs

ESCAPE_SEQUENCE_RE = re.compile(r'''
    ( \\U........      # 8-digit hex escapes
    | \\u....          # 4-digit hex escapes
    | \\x..            # 2-digit hex escapes
    | \\[0-7]{1,3}     # Octal escapes
    | \\N\{[^}]+\}     # Unicode characters by name
    | \\[\\'"abfnrtv]  # Single-character escapes
    )''', re.UNICODE | re.VERBOSE)

def decode_escapes(s):
    def decode_match(match):
        return codecs.decode(match.group(0), 'unicode-escape')

    return ESCAPE_SEQUENCE_RE.sub(decode_match, s)

And with that:

>>> print(decode_escapes('Erno \\t Rubik'))
Erno     Rubik

Most answers and explanations are not to explain what is a valid string of endDate or startDate. Danny gave us two useful example.

$('#datepicker').datepicker({
    startDate: '-2m',
    endDate: '+2d'
});

But why?let's take a look at the source code at bootstrap-datetimepicker.js. There are some code begin line 1343 tell us how does it work.

if (/^[-+]\d+[dmwy]([\s,]+[-+]\d+[dmwy])*$/.test(date)) {
            var part_re = /([-+]\d+)([dmwy])/,
                parts = date.match(/([-+]\d+)([dmwy])/g),
                part, dir;
            date = new Date();
            for (var i = 0; i < parts.length; i++) {
                part = part_re.exec(parts[i]);
                dir = parseInt(part[1]);
                switch (part[2]) {
                    case 'd':
                        date.setUTCDate(date.getUTCDate() + dir);
                        break;
                    case 'm':
                        date = Datetimepicker.prototype.moveMonth.call(Datetimepicker.prototype, date, dir);
                        break;
                    case 'w':
                        date.setUTCDate(date.getUTCDate() + dir * 7);
                        break;
                    case 'y':
                        date = Datetimepicker.prototype.moveYear.call(Datetimepicker.prototype, date, dir);
                        break;
                }
            }
            return UTCDate(date.getUTCFullYear(), date.getUTCMonth(), date.getUTCDate(), date.getUTCHours(), date.getUTCMinutes(), date.getUTCSeconds(), 0);
        }

There are four kinds of expressions.

• w means week
• m means month
• y means year
• d means day

Look at the regular expression ^[-+]\d+[dmwy]([\s,]+[-+]\d+[dmwy])*$. You can do more than these -0d or +1m.

Try harder like startDate:'+1y,-2m,+0d,-1w'.And the separator , could be one of [\f\n\r\t\v,]

When you create a StreamWriter it always create a file from scratch, you will have to create a third file and copy from target and replace what you need, and then replace the old one. But as I can see what you need is XML manipulation, you might want to use XmlDocument and modify your file using Xpath.

I have a listview which shows the Information about the all clients I am sorting the clients name using this custom comparator class. They are having some extra lerret apart from english letters which i am managing with this setStrength(Collator.SECONDARY)

 public class CustomNameComparator implements Comparator<ClientInfo> {
        @Override

    public int compare(ClientInfo o1, ClientInfo o2) { 

        Locale locale=Locale.getDefault();
        Collator collator = Collator.getInstance(locale);
        collator.setStrength(Collator.SECONDARY);
        return collator.compare(o1.title, o2.title);

    }
}


PRIMARY strength: Typically, this is used to denote differences between base characters (for example, "a" < "b"). It is the strongest difference. For example, dictionaries are divided into different sections by base character. 
SECONDARY strength: Accents in the characters are considered secondary differences (for example, "as" < "às" < "at"). Other differences between letters can also be considered secondary differences, depending on the language. A secondary difference is ignored when there is a primary difference anywhere in the strings. 
TERTIARY strength: Upper and lower case differences in characters are distinguished at tertiary strength (for example, "ao" < "Ao" < "aò"). In addition, a variant of a letter differs from the base form on the tertiary strength (such as "A" and "?"). Another example is the difference between large and small Kana. A tertiary difference is ignored when there is a primary or secondary difference anywhere in the strings. 
IDENTICAL strength: When all other strengths are equal, the IDENTICAL strength is used as a tiebreaker. The Unicode code point values of the NFD form of each string are compared, just in case there is no difference. For example, Hebrew cantellation marks are only distinguished at this strength. This strength should be used sparingly, as only code point value differences between two strings are an extremely rare occurrence. Using this strength substantially decreases the performance for both comparison and collation key generation APIs. This strength also increases the size of the collation key. 

**Here is a another way to make a rule base sorting if u need it just sharing**

/*      String rules="< å,Å< ä,Ä< a,A< b,B< c,C< d,D< é< e,E< f,F< g,G< h,H< ï< i,I"+"< j,J< k,K< l,L< m,M< n,N< ö,Ö< o,O< p,P< q,Q< r,R"+"< s,S< t,T< ü< u,U< v,V< w,W< x,X< y,Y< z,Z";
        RuleBasedCollator rbc = null;
        try {
            rbc = new RuleBasedCollator(rules);
        } catch (ParseException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        String myTitles[]={o1.title,o2.title};
        Collections.sort(Arrays.asList(myTitles), rbc);*/

findViewById also can return null if you're inside a Fragment. As described here: findViewById in Fragment

You should call getView() to return the top level View inside a Fragment. Then you can find the layout items (buttons, textviews, etc)

Slightly shorter version using methods chain:

var list = new List<string> {"a", "b", "a", "c", "a", "b"};
var q = list.GroupBy(x => x)
            .Select(g => new {Value = g.Key, Count = g.Count()})
            .OrderByDescending(x=>x.Count);

foreach (var x in q)
{
    Console.WriteLine("Value: " + x.Value + " Count: " + x.Count);
}

I am not sure if u have found the answer, but I did this and it works

public IEnumerable<string> Get()
{
    return new string[] { "value1", "value2" };
}

// GET /api/values/5
public string Get(int id)
{
    return "value";
}

// GET /api/values/5
[HttpGet]
public string GetByFamily()
{
    return "Family value";
}

Now in global.asx

routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

routes.MapHttpRoute(
    name: "DefaultApi2",
    routeTemplate: "api/{controller}/{action}",
    defaults: new { id = RouteParameter.Optional }
);

routes.MapHttpRoute(
    name: "DefaultApi",
    routeTemplate: "api/{controller}/{id}",
    defaults: new { id = RouteParameter.Optional }
);

routes.MapRoute(
    name: "Default",
    url: "{controller}/{action}/{id}",
    defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);

You can use Array.prototype.forEach, but async/await is not so compatible. This is because the promise returned from an async callback expects to be resolved, but Array.prototype.forEach does not resolve any promises from the execution of its callback. So then, you can use forEach, but you'll have to handle the promise resolution yourself.

Here is a way to read and print each file in series using Array.prototype.forEach

async function printFilesInSeries () {
  const files = await getFilePaths()

  let promiseChain = Promise.resolve()
  files.forEach((file) => {
    promiseChain = promiseChain.then(() => {
      fs.readFile(file, 'utf8').then((contents) => {
        console.log(contents)
      })
    })
  })
  await promiseChain
}

Here is a way (still using Array.prototype.forEach) to print the contents of files in parallel

async function printFilesInParallel () {
  const files = await getFilePaths()

  const promises = []
  files.forEach((file) => {
    promises.push(
      fs.readFile(file, 'utf8').then((contents) => {
        console.log(contents)
      })
    )
  })
  await Promise.all(promises)
}

You read line through while loop and through the loop you read the next line ,so just read it in while loop

 String s;
 while ((s=br.readLine()) != null) {
     System.out.println(s);
  }

You can run several copies of your script in parallel, each copy for different input data, e.g. to process all *.cfg files on 4 cores:

    ls *.cfg | xargs -P 4 -n 1 read_cfg.sh

The read_cfg.sh script takes just one parameters (as enforced by -n)

To add an insecure docker registry, add the file /etc/docker/daemon.json with the following content:

{
    "insecure-registries" : [ "hostname.cloudapp.net:5000" ]
}

and then restart docker.

For me, this code looks more explicit:

CAST(@SomeDate AS datetime) + CAST(@SomeTime AS datetime)

First 10 customers inserted into db (table customers):

select * from customers where customer_id <=

Last 10 customers inserted into db (table customers):

select * from customers where customer_id >=
(select  max(customer_id)-10 from customers)

You need to call the appendChild function to append your new element to an existing element in the DOM.

If using a Donught Chart, and you want to prevent user to trigger your event on click inside the empty space around your chart circles, you can use the following alternative :

var myDoughnutChart = new Chart(ctx).Doughnut(data);

document.getElementById("myChart").onclick = function(evt){
    var activePoints = myDoughnutChart.getSegmentsAtEvent(evt);

    /* this is where we check if event has keys which means is not empty space */       
    if(Object.keys(activePoints).length > 0)
    {
        var label = activePoints[0]["label"];
        var value = activePoints[0]["value"];
        var url = "http://example.com/?label=" + label + "&value=" + value
        /* process your url ... */
    }
};

In addition to others' answers :

static:: will be computed using runtime information.

That means you can't use static:: in a class property because properties values :

Must be able to be evaluated at compile time and must not depend on run-time information.

class Foo {
    public $name = static::class;

}

$Foo = new Foo;
echo $Foo->name; // Fatal error

Using self::

class Foo {
    public $name = self::class;

}
$Foo = new Foo;
echo $Foo->name; // Foo

Please note that the Fatal error comment in the code i made doesn't indicate where the error happened, the error happened earlier before the object was instantiated as @Grapestain mentioned in the comments

A very simple solution can be:

try {
     requestEntity = RequestEntity
     .get(new URI("user String"));
    
    return restTemplate.exchange(requestEntity, String.class);
} catch (RestClientResponseException e) {
        return ResponseEntity.status(e.getRawStatusCode()).body(e.getResponseBodyAsString());
}

Months in Calendar object start from 0

0 = January = Calendar.JANUARY
1 = february = Calendar.FEBRUARY

Wikipedia is built on MediaWiki, and here's the MediaWiki API.

Similarly:

"".contains("");     // Returns true.

Therefore, it appears that an empty string is contained in any String.

First of all you need to understand that final output of both the statements will be same i.e. to remove all the spaces from given string.

However x.replaceAll("\\s+", ""); will be more efficient way of trimming spaces (if string can have multiple contiguous spaces) because of potentially less no of replacements due the to fact that regex \\s+ matches 1 or more spaces at once and replaces them with empty string.

So even though you get the same output from both it is better to use:

x.replaceAll("\\s+", "");

I don't believe you can, though I hope that someone will prove me wrong.

I know you can print the query and its toString method will show you the sql without the replacements. That can be handy if you're building complex query strings, but it doesn't give you the full query with values.

Use -B, -A or -C option

grep --help
...
-B, --before-context=NUM  print NUM lines of leading context
-A, --after-context=NUM   print NUM lines of trailing context
-C, --context=NUM         print NUM lines of output context
-NUM                      same as --context=NUM
...

I believe the key is the realization that you are performing a double rename: master to master-old and also master-new to master.

From all the other answers I have synthesized this:

doublerename master-new master master-old

where we first have to define the doublerename Bash function:

# doublerename NEW CURRENT OLD
#   - arguments are branch names
#   - see COMMIT_MESSAGE below
#   - the result is pushed to origin, with upstream tracking info updated
doublerename() {
  local NEW=$1
  local CUR=$2
  local OLD=$3
  local COMMIT_MESSAGE="Double rename: $NEW -> $CUR -> $OLD.

This commit replaces the contents of '$CUR' with the contents of '$NEW'.
The old contents of '$CUR' now lives in '$OLD'.
The name '$NEW' will be deleted.

This way the public history of '$CUR' is not rewritten and clients do not have
to perform a Rebase Recovery.
"

  git branch --move $CUR $OLD
  git branch --move $NEW $CUR

  git checkout $CUR
  git merge -s ours $OLD -m $COMMIT_MESSAGE

  git push --set-upstream --atomic origin $OLD $CUR :$NEW
}

This is similar to a history-changing git rebase in that the branch contents is quite different, but it differs in that the clients can still safely fast-forward with git pull master.

You can create extension method like:

public static IEnumerable<TResult> LeftOuterJoin<TSource, TInner, TKey, TResult>(this IEnumerable<TSource> source, IEnumerable<TInner> other, Func<TSource, TKey> func, Func<TInner, TKey> innerkey, Func<TSource, TInner, TResult> res)
    {
        return from f in source

Generally...

Hibernate is used for handling database operations. There is a rich set of database utility functionality, which reduces your number of lines of code. Especially you have to read @Annotation of hibernate. It is an ORM framework and persistence layer.

Spring provides a rich set of the Injection based working mechanism. Currently, Spring is well-known. You have to also read about Spring AOP. There is a bridge between Struts and Hibernate. Mainly Spring provides this kind of utility.

Struts2 provides action based programming. There are a rich set of Struts tags. Struts prove action based programming so you have to maintain all the relevant control of your view.

In Addition, Tapestry is a different framework for Java. In which you have to handle only .tml (template file). You have to create two main files for any class. One is JAVA class and another one is its template. Both names are same. Tapestry automatically calls related classes.

To import files from OS X Finder into Android Studio, just drag the relevant files to your resource folder.

• Drag & Drop by default moves files to your project (not what you always want)
• Pressing ? (Alt) while dragging copies files

Don't find a permanent config option for this, but this is the workaround I'm using

Here are a few ways to create a list with N of continuous natural numbers starting from 1.

1 range:

def numbers(n): 
    return range(1, n+1);

2 List Comprehensions:

def numbers(n):
    return [i for i in range(1, n+1)]

You may want to look into the method xrange and the concepts of generators, those are fun in python. Good luck with your Learning!

Assuming you want the whole regex to ignore case, you should look for the i flag. Nearly all regex engines support it:

/G[a-b].*/i

string.match("G[a-b].*", "i")

Check the documentation for your language/platform/tool to find how the matching modes are specified.

If you want only part of the regex to be case insensitive (as my original answer presumed), then you have two options:

1. Use the (?i) and [optionally] (?-i) mode modifiers:

   (?i)G[a-b](?-i).*
   

2. Put all the variations (i.e. lowercase and uppercase) in the regex - useful if mode modifiers are not supported:

   [gG][a-bA-B].*
   

One last note: if you're dealing with Unicode characters besides ASCII, check whether or not your regex engine properly supports them.

Microsoft Core Library, ie they are at the heart of everything.

There is a more "massaged" explanation you may prefer:

"When Microsoft first started working on the .NET Framework, MSCorLib.dll was an acronym for Microsoft Common Object Runtime Library. Once ECMA started to standardize the CLR and parts of the FCL, MSCorLib.dll officially became the acronym for Multilanguage Standard Common Object Runtime Library."

Around 1999, to my personal memory, .Net was known as "COOL", so I am a little suspicious of this derivation. I never heard it called "COR", which is a silly-sounding name to a native English speaker.
