Programs & Examples On #Tabbed browsing

This will give you some control over the clicking, and looks tidy

<script>
var timeOut = 0;
function onClick(but)
{
    //code
    clearTimeout(timeOut);
    timeOut = setTimeout(function (){onClick(but)},1000);
}
</script>
<button onclick="onClick(this)">Start clicking</button>

This is the easiest one , Just define a Function and then a Tkinter Label & Button . Pressing the Button changes the text in the label. The difference that you would when defining the Label is that use the text variable instead of text. Code is tested and working.

    from tkinter import *
    master = Tk()
    
    def change_text():
        my_var.set("Second click")
    
    my_var = StringVar()
    my_var.set("First click")
    label = Label(mas,textvariable=my_var,fg="red")
    button = Button(mas,text="Submit",command = change_text)
    button.pack()
    label.pack()
    
    master.mainloop()

.register a:link{
    color:#FFFFFF;
}

The option -C works; just for clarification I'll post 2 examples:

1. creation of a tarball without the full path: full path /home/testuser/workspace/project/application.war and what we want is just project/application.war so:

   tar -cvf output_filename.tar  -C /home/testuser/workspace project
   

   Note: there is a space between workspace and project; tar will replace full path with just project .

2. extraction of tarball with changing the target path (default to ., i.e current directory)

   tar -xvf output_filename.tar -C /home/deploy/
   

   tar will extract tarball based on given path and preserving the creation path; in our example the file application.war will be extracted to /home/deploy/project/application.war.

   /home/deploy: given on extract
   project: given on creation of tarball

Note : if you want to place the created tarball in a target directory, you just add the target path before tarball name. e.g.:

tar -cvf /path/to/place/output_filename.tar  -C /home/testuser/workspace project

case_when is now a pretty clean implementation of the SQL-style case when:

structure(list(a = c(1, 3, 4, 6, 3, 2, 5, 1), b = c(1, 3, 4, 
2, 6, 7, 2, 6), c = c(6, 3, 6, 5, 3, 6, 5, 3), d = c(6, 2, 4, 
5, 3, 7, 2, 6), e = c(1, 2, 4, 5, 6, 7, 6, 3), f = c(2, 3, 4, 
2, 2, 7, 5, 2)), .Names = c("a", "b", "c", "d", "e", "f"), row.names = c(NA, 
8L), class = "data.frame") -> df


df %>% 
    mutate( g = case_when(
                a == 2 | a == 5 | a == 7 | (a == 1 & b == 4 )     ~   2,
                a == 0 | a == 1 | a == 4 |  a == 3 | c == 4       ~   3
))

Using dplyr 0.7.4

I tried some of the other solutions listed here, but during unit testing the code would throw exceptions I wanted to ignore. I ended up creating the following recursive search method that will ignore certain exceptions like PathTooLongException and UnauthorizedAccessException.

    private IEnumerable<string> RecursiveFileSearch(string path, string pattern, ICollection<string> filePathCollector = null)
    {
        try
        {
            filePathCollector = filePathCollector ?? new LinkedList<string>();

            var matchingFilePaths = Directory.GetFiles(path, pattern);

            foreach(var matchingFile in matchingFilePaths)
            {
                filePathCollector.Add(matchingFile);
            }

            var subDirectories = Directory.EnumerateDirectories(path);

            foreach (var subDirectory in subDirectories)
            {
                RecursiveFileSearch(subDirectory, pattern, filePathCollector);
            }

            return filePathCollector;
        }
        catch (Exception error)
        {
            bool isIgnorableError = error is PathTooLongException ||
                error is UnauthorizedAccessException;

            if (isIgnorableError)
            {
                return Enumerable.Empty<string>();
            }

            throw error;
        }
    }

The S parameter does not do anything on its own.

/S      Modifies the treatment of string after /C or /K (see below) 
/C      Carries out the command specified by string and then terminates  
/K      Carries out the command specified by string but remains  

Try something like this instead

Call Shell("cmd.exe /S /K" & "perl a.pl c:\temp", vbNormalFocus)

You may not even need to add "cmd.exe" to this command unless you want a command window to open up when this is run. Shell should execute the command on its own.

Shell("perl a.pl c:\temp")

-Edit-
To wait for the command to finish you will have to do something like @Nate Hekman shows in his answer here

Dim wsh As Object
Set wsh = VBA.CreateObject("WScript.Shell")
Dim waitOnReturn As Boolean: waitOnReturn = True
Dim windowStyle As Integer: windowStyle = 1

wsh.Run "cmd.exe /S /C perl a.pl c:\temp", windowStyle, waitOnReturn

The way I would go about this issue is:

If you need to write/replace the file:

echo "some text" | sudo tee /path/to/file

If you need to append to the file:

echo "some text" | sudo tee -a /path/to/file

The easiest and purest method without relying on C headers is PyYaml (documentation), which can be installed via pip install pyyaml:

#!/usr/bin/env python

import yaml

with open("example.yaml", 'r') as stream:
    try:
        print(yaml.safe_load(stream))
    except yaml.YAMLError as exc:
        print(exc)

And that's it. A plain yaml.load() function also exists, but yaml.safe_load() should always be preferred unless you explicitly need the arbitrary object serialization/deserialization provided in order to avoid introducing the possibility for arbitrary code execution.

Note the PyYaml project supports versions up through the YAML 1.1 specification. If YAML 1.2 specification support is needed, see ruamel.yaml as noted in this answer.

If you have date interval filter condition and you need to select all records which falls partly into this filter range. Assumption: records has ValidFrom and ValidTo property.

DateTime intervalDateFrom = new DateTime(1990, 01, 01);
DateTime intervalDateTo = new DateTime(2000, 01, 01);

var itemsFiltered = allItems.Where(x=> 
    (x.ValidFrom >= intervalDateFrom && x.ValidFrom <= intervalDateTo) ||
    (x.ValidTo >= intervalDateFrom && x.ValidTo <= intervalDateTo) ||
    (intervalDateFrom >= x.ValidFrom && intervalDateFrom <= x.ValidTo) ||
    (intervalDateTo >= x.ValidFrom && intervalDateTo <= x.ValidTo)
);

In your last block you have a comma after 'lang', followed immediately with a function. This is not valid json.

EDIT

It appears that the readme was incorrect. I had to to pass an array with the string 'twitter'.

var converter = new Showdown.converter({extensions: ['twitter']}); converter.makeHtml('whatever @meandave2020'); // output "<p>whatever <a href="http://twitter.com/meandave2020">@meandave2020</a></p>" 

I submitted a pull request to update this.

// 24-hour time to 12-hour time 
$time_in_12_hour_format  = date("g:i a", strtotime("13:30"));

// 12-hour time to 24-hour time 
$time_in_24_hour_format  = date("H:i", strtotime("1:30 PM"));

I think you got it a bit wrong. Someone in the thread you pasted says that you can stop anti-aliasing by using px instead of pt, not that you can force it by using the latter. I'm a bit sceptical to both of the claims though...

Installing XCode requires:

• Enrolling on the Apple website (not fun)
• Downloading a 4.7G installer

To install g++ *WITHOUT* having to download the MASSIVE 4.7G xCode install, try this package:

https://github.com/kennethreitz/osx-gcc-installer

The DMG files linked on that page are ~270M and much quicker to install. This was perfect for me, getting homebrew up and running with a minimum of hassle.

The github project itself is basically a script that repackages just the critical chunks of xCode for distribution. In order to run that script and build the DMG files, you'd need to already have an XCode install, which would kind of defeat the point, so the pre-built DMG files are hosted on the project page.

Check this PowerShell Which.

The code provided there suggests this:

($Env:Path).Split(";") | Get-ChildItem -filter notepad.exe

try this.

 int res = getResources().getIdentifier("you_image", "drawable", "com.my.package");
 preview = (ImageView) findViewById(R.id.preview);
 preview.setBackgroundResource(res);

You don't need to set the value at all. ng-model takes care of it all:

• set the input value from the model
• update the model value when you change the input
• update the input value when you change the model from js

Here's the fiddle for this: http://jsfiddle.net/terebentina/9mFpp/

At the risk of being years late and off topic - and notwithstanding @Marc's excellent insight, in Swift it looks like:

let basename = NSURL(string: "path/to/file.ext")?.URLByDeletingPathExtension?.lastPathComponent

What we ended up doing is stopped using the class components and created Functional Components, using useEffect() from the Hooks API for lifecycle methods. This allows you to still use makeStyles() with Lifecycle Methods without adding the complication of making Higher-Order Components. Which is much simpler.

Example:

import React, { useEffect, useState } from 'react';
import axios from 'axios';
import { Redirect } from 'react-router-dom';

import { Container, makeStyles } from '@material-ui/core';

import LogoButtonCard from '../molecules/Cards/LogoButtonCard';

const useStyles = makeStyles(theme => ({
  root: {
    display: 'flex',
    alignItems: 'center',
    justifyContent: 'center',
    margin: theme.spacing(1)
  },
  highlight: {
    backgroundColor: 'red',
  }
}));

// Highlight is a bool
const Welcome = ({highlight}) => { 
  const [userName, setUserName] = useState('');
  const [isAuthenticated, setIsAuthenticated] = useState(true);
  const classes = useStyles();

  useEffect(() => {
    axios.get('example.com/api/username/12')
         .then(res => setUserName(res.userName));
  }, []);

  if (!isAuthenticated()) {
    return <Redirect to="/" />;
  }
  return (
    <Container maxWidth={false} className={highlight ? classes.highlight : classes.root}>
      <LogoButtonCard
        buttonText="Enter"
        headerText={isAuthenticated && `Welcome, ${userName}`}
        buttonAction={login}
      />
   </Container>
   );
  }
}

export default Welcome;

Since nobody has mentioned it, I'd like to add that Facebook chat is written in Erlang.

You are looking for dynamic_cast<B*>(pointer)

Another option is using reduce() and new Map() to group the array. Use Spread syntax to convert set object into an array.

var myArray = [{"group":"one","color":"red"},{"group":"two","color":"blue"},{"group":"one","color":"green"},{"group":"one","color":"black"}]_x000D_
_x000D_
var result = [...myArray.reduce((c, {group,color}) => {_x000D_
  if (!c.has(group)) c.set(group, {group,color: []});_x000D_
  c.get(group).color.push(color);_x000D_
  return c;_x000D_
}, new Map()).values()];_x000D_
_x000D_
console.log(result);

In Visual Studio 2008, CTRL+E+W.

You can also debug tomcat using the community edition (Unlike what is said above).

Start tomcat in debug mode, for example like this: .\catalina.bat jpda run

In intellij: Run > Edit Configurations > +

Select "Remote" Name the connection: "somename" Set "Port:" 8000 (default 5005)

Select Run > Debug "somename"

It was giving Illegal Exception.

My workaround with code:

public void dofirst(){
    System.setProperty("webdriver.chrome.driver","D:\\Softwares\\selenium\\chromedriver_win32\\chromedriver.exe");
    WebDriver driver = new ChromeDriver();
    driver.get("http://www.facebook.com");
}

Chrome uses (a fork of) Webkit if you didn't know, which is also used by Safari. Here's a few questions that are of the same vein:

• Embedding Webkit with C#
• Embedding Gecko (Firefox engine) with C#

The webkit one isn't great as the other answer states, one version no longer works (the google code one) and the Mono one is experimental. It'd be nice if someone made the effort to make a decent .NET wrapper for it but it's not something anyone seems to want to do - which is surprising given it now has support for HTML5 and so many other features that the IE(8) engine lacks.

Update (2014)

There's new dual-licensed project that allows you embed Chrome into your .NET applications called Awesomium. It comes with a .NET api but requires quite a few hacks for rendering (the examples draw the browser window to a buffer, paint the buffer as an image and refresh on a timer).

I think this is the browser used by Origin in Battlefield 3.

Update (2016)

There is now DotnetBrowser, a commercial alternative to Awesomium. It's based off Chromium.

As an update to the OP's question, I can confirm that the timepicker found at http://jdewit.github.io/bootstrap-timepicker/ does in fact work with Bootstrap 3 now with no problems at all.

I like the solution from

http://www.nautsch.net/2008/10/28/class-von-type-parameter-java-generics/

public class Dada<T> {

    private Class<T> typeOfT;

    @SuppressWarnings("unchecked")
    public Dada() {
        this.typeOfT = (Class<T>)
                ((ParameterizedType)getClass()
                .getGenericSuperclass())
                .getActualTypeArguments()[0];
    }
...

I cannot help you much without a small (possibly reduced) snippit of the problem. If the problem is what I think it is then it's because a div by default takes up 100% width, and as such cannot be aligned.

What you may be after is to align the inline elements inside the div (such as text) with text-align:center; otherwise you may consider setting the div to display:inline-block;

If you do go down the inline-block route then you may have to consider my favorite IE hack.

width:100px;
display:inline-block;
zoom:1; //IE only
*display:inline; //IE only

Happy Coding :)

I had a similar issue. Rather than run the search through the dom every time though the loop for the select control I saved the jquery select element in a variable and did this:

function isValueInSelect($select, data_value){
    return $($select).children('option').map(function(index, opt){
        return opt.value;
    }).get().includes(data_value);
}

When creating a new project - Maven - Java application in Netbeans the IDE is not recognizing the Main class on 1st class entry. (in Step 8 below we see no classes).

When first a generic class is created and then the Main class is created Netbeans is registering the Main class and the app could be run and debugged.

Steps that worked for me:

1. Create new project - Maven - Java application (project created: mytest; package created: com.me.test)
2. Right-click package: com.me.test
3. New > Java Class > Named it 'Whatever' you want
4. Right-click package: com.me.test
5. New > Java Main Class > named it: 'Main' (must be 'Main')
6. Right click on Project mytest
7. Click on Properties
8. Click on Run > next to 'Main Class' text box: > Browse
9. You should see: com.me.test.Main
10. Select it and click "Select Main Class"

Hope this works for others as well.

I would recommend the first option, where you actually build elements using jQuery. the second approach simply sets the innerHTML property of the element to a string, which happens to be HTML, and is more error prone and less flexible.

This is how use SignarR in order to target a specific user (without using any provider):

 private static ConcurrentDictionary<string, string> clients = new ConcurrentDictionary<string, string>();

 public string Login(string username)
 {
     clients.TryAdd(Context.ConnectionId, username);            
     return username;
 }

// The variable 'contextIdClient' is equal to Context.ConnectionId of the user, 
// once logged in. You have to store that 'id' inside a dictionaty for example.  
Clients.Client(contextIdClient).send("Hello!");

If you really want to use itoa, you need to include the standard library header.

#include <stdlib.h>

I also believe that if you're on Windows (using MSVC), then itoa is actually _itoa.

See http://msdn.microsoft.com/en-us/library/yakksftt(v=VS.100).aspx

Then again, since you're getting a message from collect2, you're likely running GCC on *nix.

Can't post comments yet, but @Cristi S's answer works a treat for me.

In my scenario, I needed to keep only the most recent 3 records in Lowest_Offers for all product_ids.

Need to rework his SQL to delete - thought that this would be ok, but syntax is wrong.

DELETE from (
SELECT product_id, id, date_checked,
  ROW_NUMBER() OVER (PARTITION BY product_id ORDER BY date_checked DESC) rn
FROM lowest_offers
) tmp WHERE > 3;

Match it against a regular expression.

Re: IsNumeric() clause in MySQL??
Posted by: kevinclark ()
Date: August 08, 2005 01:01PM

I agree. Here is a function I created for MySQL 5:

CREATE FUNCTION IsNumeric (sIn varchar(1024)) RETURNS tinyint
RETURN sIn REGEXP '^(-|\\+){0,1}([0-9]+\\.[0-9]*|[0-9]*\\.[0-9]+|[0-9]+)$';

This allows for an optional plus/minus sign at the beginning, one optional decimal point, and the rest numeric digits.

You can include a project in more than one solution. I don't think a project has a concept of which solution it's part of. However, another alternative is to make the first solution build to some well-known place, and reference the compiled binaries. This has the disadvantage that you'll need to do a bit of work if you want to reference different versions based on whether you're building in release or debug configurations.

I don't believe you can make one solution actually depend on another, but you can perform your automated builds in an appropriate order via custom scripts. Basically treat your common library as if it were another third party dependency like NUnit etc.

git-subtree will help you work with multiple projects in a single tree and keep separable history for them.

The issue you have encountered is that UDFs cannot modify the Excel environment, they can only return a value to the calling cell.

There are several alternatives

1. For the sample given you don't actually need VBA. This formula will work
   ='C:\Users\UserName\Desktop\[TestSample.xlsx]Sheet1'!$B$2

2. Use a rather messy work around: See this answer

3. You can use ExecuteExcel4Macro or OLEDB

I've had the same problem.

Use CSS to hide is not the best solution, because sometimes you want users without JS can see the div.. The cleanest solution is to hide the div with JQuery. But the div is visible about 0.5 seconde, which is problematic if the div is on the top of the page.

In these cases, I use an intermediate solution, without JQuery. This one works and is immediate :

<script>document.write('<style>.js_hidden { display: none; }</style>');</script>

<div class="js_hidden">This div will be hidden for JS users, and visible for non JS users.</div>

Of course, you can still add all the effects you want on the div, JQuery toggle() for example. And you will get the best behaviour possible (imho) :

• for non JS users, the div is visible directly
• for JS users, the div is hidden and has toggle effect.

If the jar's in your classpath, and you know its Main class, you can just invoke the main class. Using DITA-OT as an example:

import org.dita.dost.invoker.CommandLineInvoker;
....
CommandLineInvoker.main('-f', 'html5', '-i', 'samples/sequence.ditamap', '-o', 'test')

Note this will make the subordinate jar share memory space and a classpath with your jar, with all the potential for interference that can cause. If you don't want that stuff polluted, you have other options, as mentioned above - namely:

• create a new ClassLoader with the jar in it. This is more safe; you can at least isolate the new jar's knowledge to a core classloader if you architect things with the knowledge that you'll be making use of alien jars. It's what we do in my shop for our plugins system; the main application is a tiny shell with a ClassLoader factory, a copy of the API, and knowledge that the real application is the first plugin for which it should build a ClassLoader. Plugins are a pair of jars - interface and implementation - that are zipped up together. The ClassLoaders all share all the interfaces, while each ClassLoader only has knowledge of its own implementation. The stack's a little complex, but it passes all tests and works beautifully.
• use Runtime.getRuntime.exec(...) (which wholly isolates the jar, but has the normal "find the application", "escape your strings right", "platform-specific WTF", and "OMG System Threads" pitfalls of running system commands.

The problem is that thread_obj.start() returns immediately. The child thread that you spawned executes in its own context, with its own stack. Any exception that occurs there is in the context of the child thread, and it is in its own stack. One way I can think of right now to communicate this information to the parent thread is by using some sort of message passing, so you might look into that.

Try this on for size:

import sys
import threading
import Queue


class ExcThread(threading.Thread):

    def __init__(self, bucket):
        threading.Thread.__init__(self)
        self.bucket = bucket

    def run(self):
        try:
            raise Exception('An error occured here.')
        except Exception:
            self.bucket.put(sys.exc_info())


def main():
    bucket = Queue.Queue()
    thread_obj = ExcThread(bucket)
    thread_obj.start()

    while True:
        try:
            exc = bucket.get(block=False)

How much data can be added in java.util.List in Java at the maximum?

This is very similar to Theoretical limit for number of keys (objects) that can be stored in a HashMap?

The documentation of java.util.List does not explicitly documented any limit on the maximum number of elements. The documentation of List.toArray however, states that ...

Return an array containing all of the elements in this list in proper sequence (from first to last element); would have trouble implementing certain methods faithfully, such as

... so strictly speaking it would not be possible to faithfully implement this method if the list had more than 2³¹-1 = 2147483647 elements since that is the largest possible array.

Some will argue that the documentation of size()...

Returns the number of elements in this list. If this list contains more than Integer.MAX_VALUE elements, returns Integer.MAX_VALUE.

...indicates that there is no upper limit, but this view leads to numerous inconsistencies. See this bug report.

Is there any default size an array list?

If you're referring to ArrayList then I'd say that the default size is 0. The default capacity however (the number of elements you can insert, without forcing the list to reallocate memory) is 10. See the documentation of the default constructor.

The size limit of ArrayList is Integer.MAX_VALUE since it's backed by an ordinary array.

I'm sure you can with Mongo (more familiar with it), and pretty sure you can with couch too.

Both are documented oriented (JSON-based) so there would be no "columns" but rather fields in documents -- but they can be fully dynamic.

They both do it you may want to look at other factors on which to use: other features you care about, popularity, etc. Google insights, indeed.com job posts would be ways to look at popularity.

You could just try it i think you should be able to have mongo running in 5 minutes.

Training set: A set of examples used for learning, that is to fit the parameters [i.e., weights] of the classifier.

Validation set: A set of examples used to tune the parameters [i.e., architecture, not weights] of a classifier, for example to choose the number of hidden units in a neural network.

Test set: A set of examples used only to assess the performance [generalization] of a fully specified classifier.

From ftp://ftp.sas.com/pub/neural/FAQ1.txt section "What are the population, sample, training set, design set, validation"

The error surface will be different for different sets of data from your data set (batch learning). Therefore if you find a very good local minima for your test set data, that may not be a very good point, and may be a very bad point in the surface generated by some other set of data for the same problem. Therefore you need to compute such a model which not only finds a good weight configuration for the training set but also should be able to predict new data (which is not in the training set) with good error. In other words the network should be able to generalize the examples so that it learns the data and does not simply remembers or loads the training set by overfitting the training data.

The validation data set is a set of data for the function you want to learn, which you are not directly using to train the network. You are training the network with a set of data which you call the training data set. If you are using gradient based algorithm to train the network then the error surface and the gradient at some point will completely depend on the training data set thus the training data set is being directly used to adjust the weights. To make sure you don't overfit the network you need to input the validation dataset to the network and check if the error is within some range. Because the validation set is not being using directly to adjust the weights of the netowork, therefore a good error for the validation and also the test set indicates that the network predicts well for the train set examples, also it is expected to perform well when new example are presented to the network which was not used in the training process.

Early stopping is a way to stop training. There are different variations available, the main outline is, both the train and the validation set errors are monitored, the train error decreases at each iteration (backprop and brothers) and at first the validation error decreases. The training is stopped at the moment the validation error starts to rise. The weight configuration at this point indicates a model, which predicts the training data well, as well as the data which is not seen by the network . But because the validation data actually affects the weight configuration indirectly to select the weight configuration. This is where the Test set comes in. This set of data is never used in the training process. Once a model is selected based on the validation set, the test set data is applied on the network model and the error for this set is found. This error is a representative of the error which we can expect from absolutely new data for the same problem.

EDIT:

Also, in the case you do not have enough data for a validation set, you can use crossvalidation to tune the parameters as well as estimate the test error.

This worked form me.. PHP Code on page.php

 $query_de="sql statements here";
 $sql_de = sqlsrv_query($conn,$query_de);
      if ($sql_de)
      {
        echo "SQLSuccess";
       }
         exit();

and then AJAX Code has bellow

jQuery.ajax({
                    url  : "page.php",
                    type : "POST",
                    data : {
                            buttonsave   : 1,
                            var1         : val1,
                            var2         : val2,
                              },
                  success:function(data)
                           {
                     if(jQuery.trim(data) === "SQLSuccess")
                                   {
                           alert("Se agrego correctamente");
                          // alert(data);
                                      } else { alert(data);}
                              },
                   error: function(error)
                           {
                    alert("Error AJAX not working: "+ error );
                              } 
               }); 

NOTE: the word 'SQLSuccess' must be received from PHP

You can, if uploading an entire folder is an option for you

<input type="file" webkitdirectory directory multiple/>

change event will contain:

.target.files[...].webkitRelativePath: "FOLDER/FILE.ext"

You can determine that the connection is lost by making failed XHR requests.

The standard approach is to retry the request a few times. If it doesn't go through, alert the user to check the connection, and fail gracefully.

Sidenote: To put the entire application in an "offline" state may lead to a lot of error-prone work of handling state.. wireless connections may come and go, etc. So your best bet may be to just fail gracefully, preserve the data, and alert the user.. allowing them to eventually fix the connection problem if there is one, and to continue using your app with a fair amount of forgiveness.

Sidenote: You could check a reliable site like google for connectivity, but this may not be entirely useful as just trying to make your own request, because while Google may be available, your own application may not be, and you're still going to have to handle your own connection problem. Trying to send a ping to google would be a good way to confirm that the internet connection itself is down, so if that information is useful to you, then it might be worth the trouble.

Sidenote: Sending a Ping could be achieved in the same way that you would make any kind of two-way ajax request, but sending a ping to google, in this case, would pose some challenges. First, we'd have the same cross-domain issues that are typically encountered in making Ajax communications. One option is to set up a server-side proxy, wherein we actually ping google (or whatever site), and return the results of the ping to the app. This is a catch-22 because if the internet connection is actually the problem, we won't be able to get to the server, and if the connection problem is only on our own domain, we won't be able to tell the difference. Other cross-domain techniques could be tried, for example, embedding an iframe in your page which points to google.com, and then polling the iframe for success/failure (examine the contents, etc). Embedding an image may not really tell us anything, because we need a useful response from the communication mechanism in order to draw a good conclusion about what's going on. So again, determining the state of the internet connection as a whole may be more trouble than it's worth. You'll have to weight these options out for your specific app.

Now that Apple has non-cosensually updated all MacOS users to zsh, the correct answer doesn't work anymore.

git reset --soft HEAD^
zsh: no matches found: HEAD^

You can prevent the shell from treating the ^ as a special character by single quoting it.

git reset --soft 'HEAD^'

Alternatively you can disable this behavior in your shell. by updating your ~/.zshrc with

unsetopt nomatch

On my clean macOS 10.15.7, I needed to brew link gnupg && brew unlink gnupg first and then used Ashish's answer to use gpg instead of gpg2. I also had to chown a few directories. before the un/link.

If you want to use the call operator, the arguments can be an array stored in a variable:

$prog = 'c:\windows\system32\cmd.exe'
$myargs = '/c','dir','/x'
& $prog $myargs

The call operator works with ApplicationInfo objects too.

$prog = get-command cmd
$myargs = -split '/c dir /x'
& $prog $myargs

You can go settings, select packages and type atom-runner there if your browser can't open this link.

To run your code do Alt+R if you're using Windows in Atom.

the answers here are correct and i liked @Jyo the Whiff idea of a show and hide fragment implementation except the way he has it currently would hide the fragment on the first run so i added a slight change in that i added the isAdded check and show the fragment if its not already

public void showHideCardPreview(int id) {
    FragmentManager fm = getSupportFragmentManager();
    Bundle b = new Bundle();
    b.putInt(Constants.CARD, id);
    cardPreviewFragment.setArguments(b);
    FragmentTransaction ft = fm.beginTransaction()
        .setCustomAnimations(android.R.anim.fade_in, android.R.anim.fade_out);
    if (!cardPreviewFragment.isAdded()){
        ft.add(R.id.full_screen_container, cardPreviewFragment);
        ft.show(cardPreviewFragment);
    } else {
        if (cardPreviewFragment.isHidden()) {
            Log.d(TAG,"++++++++++++++++++++ show");
            ft.show(cardPreviewFragment);
        } else {
            Log.d(TAG,"++++++++++++++++++++ hide");
            ft.hide(cardPreviewFragment);
        }
    }

    ft.commit();
} 

A tool that helps me a lot to debug ElasticSearch is ElasticHQ. Basically, it is an HTML file with some JavaScript. No need to install anywhere, let alone in ES itself: just download it, unzip int and open the HTML file with a browser.

Not sure it is the best tool for ES heavy users. Yet, it is really practical to whoever is in a hurry to see the entries.

In the case of nested tables, some DBMS require to use an alias like MySQL and Oracle but others do not have such a strict requirement, but still allow to add them to substitute the result of the inner query.

You do not need the latex2exp package to do what you wanted to do. The following code would do the trick.

ggplot(smr, aes(Fuel.Rate, Eng.Speed.Ave., color=Eng.Speed.Max.)) + 
  geom_point() + 
  labs(title=expression("Fuel Efficiency"~(alpha*Omega)), 
color=expression(alpha*Omega), x=expression(Delta~price))

Also, some comments (unanswered as of this point) asked about putting an asterisk (*) after a Greek letter. expression(alpha~"*") works, so I suggest giving it a try.

More comments asked about getting ? Price and I find the most straightforward way to achieve that is expression(Delta~price)). If you need to add something before the Greek letter, you can also do this: expression(Indicative~Delta~price) which gets you:

For SQL-based databases:

1. Not taking advantage of CLUSTERED INDEXES or choosing the wrong column(s) to CLUSTER.
2. Not using a SERIAL (autonumber) datatype as a PRIMARY KEY to join to a FOREIGN KEY (INT) in a parent/child table relationship.
3. Not UPDATING STATISTICS on a table when many records have been INSERTED or DELETED.
4. Not reorganizing (i.e. unloading, droping, re-creating, loading and re-indexing) tables when many rows have been inserted or deleted (some engines physically keep deleted rows in a table with a delete flag.)
5. Not taking advantage of FRAGMENT ON EXPRESSION (if supported) on large tables which have high transaction rates.
6. Choosing the wrong datatype for a column!
7. Not choosing a proper column name.
8. Not adding new columns at the end of the table.
9. Not creating proper indexes to support frequently used queries.
10. creating indexes on columns with few possible values and creating unnecessary indexes.
    ...more to be added.

I know this is an old question but I'm pretty proud of this solution :) It only handles numbers less than 1000 but could easily be expanded to include however large you'd need by adding on to the 'numeralCodes' 2D array.

                    ["","C","CC","CCC","CD","D","DC","DCC","DCCC","CM"]];        // Hundreds_x000D_

I tried what @willll said, and it worked. I didint find exactly the .exe named after my project, but I did kill some weird looking tasks (after checking on the internet they were not critical), and it worked.

Adopting from naveen's and original OP's posts I ended up with a reusable method stub that accepts both strings and / or JS Date objects.

I named it gregorianAge() because this calculation gives exactly how we denote age using Gregorian calendar. i.e. Not counting the end year if month and day is before the month and day of the birth year.

Download and install this plugin JSToolNpp ,Then perform operations like this Plugins | JSTool | JSFormat. If you don’t want to install plugins, you can perform JSON beautification operations on JSON Formatter

Set the second function parameter to true if you require an associative array

Some versions of php require a 2nd paramter of true if you require an associative array

$json  = '[{"var1":"9","var2":"16","var3":"16"},{"var1":"8","var2":"15","var3":"15"}]';
$array = json_decode( $json, true );

Angular 2 completely ignores type=date. If you change type to text you'll see that your input has two-way binding.

<input type='text' #myDate [(ngModel)]='demoUser.date'/><br>

Here is pretty bad advise with better one to follow:

My project originally used jQuery. So, I'm using jQuery datepicker for now, hoping that angular team will fix the original issue. Also it's a better replacement because it has cross-browser support. FYI, input=date doesn't work in Firefox.

Good advise: There are few pretty good Angular2 datepickers:

• https://github.com/emirdeliz/meus-projetos/tree/master/angular2-schedule/app/frontend/components/datepicker

• https://github.com/MrPardeep/Angular2-DatePicker

• https://www.npmjs.com/package/ng2-datepicker

If the list contains unhashable items, you can use Alex Martelli's solution but with a list instead of a set, though it's slower for larger inputs: O(N^2).

def has_duplicates(iterable):
    seen = []
    for x in iterable:
        if x in seen:
            return True
        seen.append(x)
    return False

Use ApacheCommonUtils to generate a random long within a given range, and then create Date out of that long.

Example:

import org.apache.commons.math.random.RandomData;

import org.apache.commons.math.random.RandomDataImpl;

public Date nextDate(Date min, Date max) {

RandomData randomData = new RandomDataImpl();

return new Date(randomData.nextLong(min.getTime(), max.getTime()));

}

You can use .indexOf():

if(str.indexOf(substr) > -1) {

}

You can do it in multiple ways:
1. Using greater as comparison function :

 #include <bits/stdc++.h>

using namespace std;

int main()
{
    priority_queue<int,vector<int>,greater<int> >pq;
    pq.push(1);
    pq.push(2);
    pq.push(3);

    while(!pq.empty())
    {
        int r = pq.top();
        pq.pop();
        cout<<r<< " ";
    }
    return 0;
}

2. Inserting values by changing their sign (using minus (-) for positive number and using plus (+) for negative number :

int main()
{
    priority_queue<int>pq2;
    pq2.push(-1); //for +1
    pq2.push(-2); //for +2
    pq2.push(-3); //for +3
    pq2.push(4);  //for -4

    while(!pq2.empty())
    {
        int r = pq2.top();
        pq2.pop();
        cout<<-r<<" ";
    }

    return 0;
}

3. Using custom structure or class :

struct compare
{
    bool operator()(const int & a, const int & b)
    {
        return a>b;
    }
};

int main()
{

    priority_queue<int,vector<int>,compare> pq;
    pq.push(1);
    pq.push(2);
    pq.push(3);

    while(!pq.empty())
    {
        int r = pq.top();
        pq.pop();
        cout<<r<<" ";
    }

    return 0;
}

4. Using custom structure or class you can use priority_queue in any order. Suppose, we want to sort people in descending order according to their salary and if tie then according to their age.

    struct people
    {
        int age,salary;

    };
    struct compare{
    bool operator()(const people & a, const people & b)
        {
            if(a.salary==b.salary)
            {
                return a.age>b.age;
            }
            else
            {
                return a.salary>b.salary;
            }

    }
    };
    int main()
    {

        priority_queue<people,vector<people>,compare> pq;
        people person1,person2,person3;
        person1.salary=100;
        person1.age = 50;
        person2.salary=80;
        person2.age = 40;
        person3.salary = 100;
        person3.age=40;


        pq.push(person1);
        pq.push(person2);
        pq.push(person3);

        while(!pq.empty())
        {
            people r = pq.top();
            pq.pop();
            cout<<r.salary<<" "<<r.age<<endl;
    }

5. Same result can be obtained by operator overloading :

   struct people
   {
   int age,salary;
   
   bool operator< (const people & p)const
   {
       if(salary==p.salary)
       {
           return age>p.age;
       }
       else
       {
           return salary>p.salary;
       }
   }};
   

   In main function :

   priority_queue<people> pq;
   people person1,person2,person3;
   person1.salary=100;
   person1.age = 50;
   person2.salary=80;
   person2.age = 40;
   person3.salary = 100;
   person3.age=40;
   
   
   pq.push(person1);
   pq.push(person2);
   pq.push(person3);
   
   while(!pq.empty())
   {
       people r = pq.top();
       pq.pop();
       cout<<r.salary<<" "<<r.age<<endl;
   }
   

If you happend to insert colums with UUIDs (which is not exactly your case) and to add to @Dennis answer (I can't comment yet), be advise than using gen_random_uuid() (requires PG 9.4 and pgcrypto module) is (a lot) faster than uuid_generate_v4()

=# explain analyze select uuid_generate_v4(),* from generate_series(1,10000);
                                                        QUERY PLAN

 Planning time: 0.157 ms
 Execution time: 13353.098 ms
(3 filas)

vs

=# explain analyze select gen_random_uuid(),* from generate_series(1,10000);
                                                        QUERY PLAN

 Execution time: 503.818 ms
(3 filas)

Also, it's the suggested official way to do it

Note

If you only need randomly-generated (version 4) UUIDs, consider using the gen_random_uuid() function from the pgcrypto module instead.

This droped insert time from ~2 hours to ~10 minutes for 3.7M of rows.

check whether there is a comma at the end.

I think this is a better way to unambiguously identify a clone of a repository.

git config --get remote.origin.url and checking to make sure that the origin matches ssh://your/repo.

IntelliJ IDEA does not have an action to add imports. Rather it has the ability to do such as you type. If you enable the "Add unambiguous imports on the fly" in Settings > Editor > General > Auto Import, IntelliJ IDEA will add them as you type without the need for any shortcuts. You can also add classes and packages to exclude from auto importing to make a class you use heavily, that clashes with other classes of the same name, unambiguous.

For classes that are ambiguous (or is you prefer to have the "Add unambiguous imports on the fly" option turned off), just type the name of the class (just the name is OK, no need to fully qualify). Use code completion and select the particular class you want:

Notice the fully qualified names to the right. When I select the one I want and hit enter, IDEA will automatically add the import statement. This works the same if I was typing the name of a constructor. For static methods, you can even just keep typing the method you want. In the following screenshot, no "StringUtils" class is imported yet.

Alternatively, type the class name and then hit Alt+Enter or ?+Enter to "Show intention actions and quick-fixes" and then select the import option.

Although I've never used it, I think the Eclipse Code Formatter third party plug-in will do what you want. It lists "emulates Eclipse's imports optimizing" as a feature. See its instructions for more information. But in the end, I suspect you'll find the built in IDEA features work fine once you get use to their paradigm. In general, IDEA uses a "develop by intentions" concept. So rather than interrupting my development work to add an import statement, I just type the class I want (my intention) and IDEA automatically adds the import statement for the class for me.

What you've done doesn't work because you're binding an event to a function. As such, it's the event which defines the parameters that will be called when the event is raised (i.e. JavaScript doesn't know about your parameter in the function you've bound to onclick so can't pass anything into it).

You could do this however:

<input type="button" value="Click me" id="myButton"/>

<script type="text/javascript">

    var myButton = document.getElementById("myButton");

    var myMessage = "it's working";

    var myDelegate = function(message) {
        alert(message);
    }

    myButton.onclick = function() { 
        myDelegate(myMessage);
    };

</script>

I use text-shadow solution as some others mentioned here:

text-shadow: 0 0 0.01px;

the difference is that I do not specify shadow color, so this solution is universal for all font colors.

First of all, I wouldn't use a multi-dimensional array. Only ever seen bad things come of it.

Set up your variable like this:

IEnumerable<IEnumerable<string>> data = new[] {
    new[]{"...", "...", "..."},
    ... etc ...
};

Then you'd simply go:

var firsts = data.Select(x => x.FirstOrDefault()).Where(x => x != null); 

The Where makes sure it prunes any nulls if you have an empty list as an item inside.

Alternatively you can implement it as:

string[][] = new[] {
    new[]{"...","...","..."},
    new[]{"...","...","..."},
    ... etc ...
};

This could be used similarly to a [x,y] array but it's used like this: [x][y]

First of all, this approach won't scale in the large, you'll need a separate index from words to item (like an inverted index).

If your data is not large, you can do

SELECT DISTINCT(name) FROM mytable WHERE name LIKE '%mall%' OR description LIKE '%mall%'

using OR if you have multiple keywords.

I always use :

if (row["value"] != DBNull.Value)
  someObject.Member = row["value"];

Found it short and comprehensive.

OK, I have found the problem.

I use some reporting plugins. In the documentation of the failsafe-maven-plugin I found, that the <encoding> configuration - of course - uses ${project.reporting.outputEncoding} by default.

So I added the property as a child element of the project element and everything is fine now:

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
</properties>

Simplified update query using JOIN-ing multiple tables.

   UPDATE
        first_table ft
        JOIN second_table st ON st.some_id = ft.some_id
        JOIN third_table tt  ON tt.some_id = st.some_id
        .....
    SET
        ft.some_column = some_value
    WHERE ft.some_column = 123456 AND st.some_column = 123456

Note - first_table, second_table, third_table and some_column like 123456 are demo table names, column names and ids. Replace them with the valid names.

Basically, to make a cross domain AJAX requests, the requested server should allow the cross origin sharing of resources (CORS). You can read more about that from here: http://www.html5rocks.com/en/tutorials/cors/

In your scenario, you are setting the headers in the client which in fact needs to be set into http://localhost:8080/app server side code.

If you are using PHP Apache server, then you will need to add following in your .htaccess file:

Header set Access-Control-Allow-Origin "*"

Whenever I have had odd issues like this, I usually sit down with a tool like WireShark and look at the raw data being passed back and forth. You might be surprised where things are being disconnected, and you are only being notified when you try and read.

If you are getting this error on the WordPress website, check the below solution.

1. Corrupted Browser Cache & Cookies: Delete your Cookies and clear your cache
2. Restart your server

Try this It may be more appropriate for you

#container { display:block; }_x000D_
@media only screen and (orientation:portrait){_x000D_
  #container {  _x000D_
    height: 100vw;_x000D_
    -webkit-transform: rotate(90deg);_x000D_
    -moz-transform: rotate(90deg);_x000D_
    -o-transform: rotate(90deg);_x000D_
    -ms-transform: rotate(90deg);_x000D_

     -o-transform: rotate(0deg);_x000D_
     -ms-transform: rotate(0deg);_x000D_
     transform: rotate(0deg);_x000D_
  }_x000D_
}

<div id="container">_x000D_
    <!-- your html for your website -->_x000D_
    <H1>This text is always in Landscape Mode</H1>_x000D_
</div>

This will automatically manage even rotation.

You just need to convert your dates to UNIX_TIMESTAMP. You can write your query like this:

SELECT *
FROM eventList
WHERE
  date BETWEEN
      UNIX_TIMESTAMP('2013/03/26')
      AND
      UNIX_TIMESTAMP('2013/03/27 23:59:59');

When you don't specify the time, MySQL will assume 00:00:00 as the time for the given date.

In your code behind, set the window's DataContext to the dictionary. In your XAML, you can write:

<ListView ItemsSource="{Binding}" />

This will bind the ListView to the dictionary.

For more complex scenarios, this would be a subset of techniques behind the MVVM pattern.

Or if you're using dotnet Core,

add to your .csproj file

  <ItemGroup>
    <PackageReference Include="Newtonsoft.Json" Version="9.0.1" />
  </ItemGroup>

And

dotnet restore

Using top command is the simplest way to check memory usage of the program. RES column shows the real physical memory that is occupied by a process.

For my case, I had a 10g file read in java and each time I got outOfMemory exception. This happened when the value in the RES column reached to the value set in -Xmx option. Then by increasing the memory using -Xmx option everything went fine.

The correct answer is

Options -Indexes

You must have been thinking of

AllowOverride All

https://httpd.apache.org/docs/2.2/howto/htaccess.html

.htaccess files (or "distributed configuration files") provide a way to make configuration changes on a per-directory basis. A file, containing one or more configuration directives, is placed in a particular document directory, and the directives apply to that directory, and all subdirectories thereof.

If you use %pylab inline you can (on a new line) insert the following command:

%pylab inline
pylab.rcParams['figure.figsize'] = (10, 6)

This will set all figures in your document (unless otherwise specified) to be of the size (10, 6), where the first entry is the width and the second is the height.

See this SO post for more details. https://stackoverflow.com/a/17231361/1419668

I did this:

git ls-files | xargs file | grep "ASCII" | cut -d : -f 1 | xargs wc -l

this works if you count all text files in the repository as the files of interest. If some are considered documentation, etc, an exclusion filter can be added.

If you want to use the image as a CSS background, there is an elegant solution. Simply use cover or contain in the background-size CSS3 property.

.container {_x000D_
  width: 150px;_x000D_
  height: 100px;_x000D_
  background-image: url("http://i.stack.imgur.com/2OrtT.jpg");_x000D_
  background-size: cover;_x000D_
  background-repeat: no-repeat;_x000D_
  background-position: 50% 50%;_x000D_
}

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

While cover will give you a scaled up image, contain will give you a scaled down image. Both will preserve the pixel aspect ratio.

This approach has the advantage of being friendly to Retina displays as per Thomas Fuchs' quick guide.

It's worth mentioning that browser support for both attributes excludes IE6-8.

If we have a single server we can directly include it in the proxy_pass. But in case if we have many servers we use upstream to maintain the servers. Nginx will load-balance based on the incoming traffic.

If the goal is to seperate two elements, you can use CSS like below:

A<span style={{paddingLeft: '20px'}}>B</span>

As Fredrik mentions in his answer, the simple way to achieve this is to place the JTextArea in a JScrollPane. This will allow scrolling of the view area of the JTextArea.

Just for the sake of completeness, the following is how it could be achieved:

JTextArea ta = new JTextArea();
JScrollPane sp = new JScrollPane(ta);   // JTextArea is placed in a JScrollPane.

Once the JTextArea is included in the JScrollPane, the JScrollPane should be added to where the text area should be. In the following example, the text area with the scroll bars is added to a JFrame:

JFrame f = new JFrame();
f.getContentPane().add(sp);

Thank you kd304 for mentioning in the comments that one should add the JScrollPane to the container rather than the JTextArea -- I feel it's a common error to add the text area itself to the destination container rather than the scroll pane with text area.

The following articles from The Java Tutorials has more details:

• How to Use Scroll Panes
• How to Use Text Areas

You can declare the array in C++ in these type of ways. If you know the array size then you should declare the array for: integer: int myArray[array_size]; Double: double myArray[array_size]; Char and string : char myStringArray[array_size]; The difference between char and string is as follows

char myCharArray[6]={'a','b','c','d','e','f'};
char myStringArray[6]="abcdef";

If you don't know the size of array then you should leave the array blank like following.

integer: int myArray[array_size];

Double: double myArray[array_size];

Simple Answer - using UI Bootstrap (ui.bootstrap.tooltip)

There seem to be a bunch of very complex answers to this question. Here's what worked for me.

1. Install UI Bootstrap - $ bower install angular-bootstrap

2. Inject UI Bootstrap as a dependency - angular.module('myModule', ['ui.bootstrap']);

3. Use the uib-tooltip directive in your html.

<button class="btn btn-default"
        type="button"
        uib-tooltip="I'm a tooltip!">
     I'm a button!
</button>

That code is invalid as you can only pass variables into language constructs. empty() is a language construct.

You have to do this in two lines:

$result = array_intersect($people, $criminals);
$result = !empty($result);

Here, I'll over-architect the answer using LINQ. Just shows that there's more than 'n' ways to cook an egg:

public int countTrue(string data)
{
    string[] splitdata = data.Split(',');

    var results = from p in splitdata
            where p.Contains("true")
            select p;

    return results.Count();
}

Something similar to Google Ads, from the documentation:

public AdRequest.Builder addTestDevice (String deviceId)

Causes a device to receive test ads. The deviceId can be obtained by viewing the logcat output after creating a new ad. For emulators, use DEVICE_ID_EMULATOR.

for example my Test Device id displayed in LogCat is "B86BC9402A69B031A516BC57F7D3063F":

AdRequest adRequest = new AdRequest.Builder() 
        .addTestDevice(AdRequest.DEVICE_ID_EMULATOR)
        .addTestDevice("B86BC9402A69B031A516BC57F7D3063F")
        .build();

There are two steps:

1. You must set an appropriate width for GridView like this: Width="2000px".
2. You can set width of Colum by setting [ItemStyle-Width] Like this: ItemStyle-Width="300px".

** You can set width by setting fixed Pixels like "150 px" or by percentage like"10%".

If all the other solutions above don't work you can try checking the ownership of /var/run/docker.sock:

ls -l /var/run/docker.sock

If you're not the owner then change ownership with the command:

sudo chown *your-username* /var/run/docker.sock

Then you can go ahead and try executing the Docker commands hassle-free :D

Add this to your dialog declaration

my: "center",
at: "center",
of: window

Example :

$("#dialog").dialog({
       autoOpen: false,
        height: "auto",
        width: "auto",
        modal: true,
        position: {
            my: "center",
            at: "center",
            of: window
        }
})

Try to import

java.util.List;

instead of

java.awt.List;

The 1s are because everything is perfectly correlated with itself, and the NAs are because there are NAs in your variables.

You will have to specify how you want R to compute the correlation when there are missing values, because the default is to only compute a coefficient with complete information.

You can change this behavior with the use argument to cor, see ?cor for details.

as @MikeMiller pointed out, To exit scale mode: Right Ctrl (Host Key) + C
but for users who DON'T have a Right Ctrl (Host Key)
(such as MS Surface Pro users: we only have a Left Ctrl key), u need to go into Virtualbox>>File>>Preferences>>Input>>VirtualMachine tab>>change Host key Combination to one that works for ya(I used Ctrl+Shift+Alt which doesn't seem to be in use already)

This should work.

$("#country [value='ID']").attr("selected","selected");

If you have function calls bound to the element just follow it with something like

$("#country").change();

Autolink phone does not worked for me. The following worked like a charm,

TextView tv = (TextView) findViewById(R.id.emergencynos);
String html2="<br><br>Fire - <b><a href=tel:997>997</a> </b></br></br>";        
tv.append(Html.fromHtml(html2));
tv.setMovementMethod(LinkMovementMethod.getInstance());

Since the value of $var is the empty string, this:

if [ $var == $var1 ]; then

expands to this:

if [ == abcd ]; then

which is a syntax error.

You need to quote the arguments:

if [ "$var" == "$var1" ]; then

You can also use = rather than ==; that's the original syntax, and it's a bit more portable.

If you're using bash, you can use the [[ syntax, which doesn't require the quotes:

if [[ $var = $var1 ]]; then

Even then, it doesn't hurt to quote the variable reference, and adding quotes:

if [[ "$var" = "$var1" ]]; then

might save a future reader a moment trying to remember whether [[ ... ]] requires them.

LayoutInflater.from(context).inflate(R.layout.row_payment_gateway_item, null);

svn revert deletedDirectory

Here's the documentation for the svn revert command.

EDIT

If deletedDirectory was deleted using rmdir and not svn rm, you'll need to do

svn update deletedDirectory

instead.

You can create a custom link as described here using a small jQuery script

$('.linkPinIt').click(function(){
    var url = $(this).attr('href');
    var media = $(this).attr('data-image');
    var desc = $(this).attr('data-desc');
    window.open("//www.pinterest.com/pin/create/button/"+
    "?url="+url+
    "&media="+media+
    "&description="+desc,"_blank","top=0,right=0,width=750,height=320");
    return false; 
});

this will work for all links with class linkPinItwhich have the image and the description stored in the HTML 5 data attributes data-image and data-desc

<a href="https%3A%2F%2Fwww.flickr.com%2Fphotos%2Fkentbrew%2F6851755809%2F" 
   data-image="https%3A%2F%2Fc4.staticflickr.com%2F8%2F7027%2F6851755809_df5b2051c9_b.jpg" 
   data-desc="Title for Pinterest Photo" class="linkPinIt">
    Pin it!
</a>

Semaphores are act like thread limiters.

Example: If you have a pool of 100 threads and you want to perform some DB operation. If 100 threads access the DB at a given time, then there may be locking issue in DB so we can use semaphore which allow only limited thread at a time.Below Example allow only one thread at a time. When a thread call the acquire() method, it will then get the access and after calling the release() method, it will release the acccess so that next thread will get the access.

    package practice;
    import java.util.concurrent.Semaphore;

    public class SemaphoreExample {
        public static void main(String[] args) {
            Semaphore s = new Semaphore(1);
            semaphoreTask s1 = new semaphoreTask(s);
            semaphoreTask s2 = new semaphoreTask(s);
            semaphoreTask s3 = new semaphoreTask(s);
            semaphoreTask s4 = new semaphoreTask(s);
            semaphoreTask s5 = new semaphoreTask(s);
            s1.start();
            s2.start();
            s3.start();
            s4.start();
            s5.start();
        }
    }

    class semaphoreTask extends Thread {
        Semaphore s;
        public semaphoreTask(Semaphore s) {
            this.s = s;
        }
        @Override
        public void run() {
            try {
                s.acquire();
                Thread.sleep(1000);
                System.out.println(Thread.currentThread().getName()+" Going to perform some operation");
                s.release();
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        } 
    }

Found the list in a similar question, previously on StackOverflow:

Hash Table - used for fast data lookup - symbol table for compilers, database indexing, caches,Unique data representation.

Trie - dictionary, such as one found on a mobile telephone for autocompletion and spell-checking.

Suffix tree - fast full text searches used in most word processors.

Stack - undo\redo operation in word processors, Expression evaluation and syntax parsing, many virtual machines like JVM are stack oriented.

Queues - Transport and operations research where various entities are stored and held to be processed later ie the queue performs the function of a buffer.

if your intention is send the full array from the html to the controller, can use this:

from the blade.php:

 <input type="hidden" name="quotation" value="{{ json_encode($quotation,TRUE)}}"> 

in controller

    public function Get(Request $req) {

    $quotation = array('quotation' => json_decode($req->quotation));

    //or

    return view('quotation')->with('quotation',json_decode($req->quotation))


}

I've figured out what the issue is the namespace is ambigious in the loggerFactory.AddLog4Net(). Here is a brief summary of how I added log4Net to my Asp.Net Core project.

1. Add the nugget package Microsoft.Extensions.Logging.Log4Net.AspNetCore

2. Add the log4net.config file in your root application folder

3. Open the Startup.cs file and change the Configure method to add log4net support with this line loggerFactory.AddLog4Net

First you have to import the package using Microsoft.Extensions.Logging; using the using statement

Here is the entire method, you have to prefix the ILoggerFactory interface with the namespace

 public void Configure(IApplicationBuilder app, IHostingEnvironment env, NorthwindContext context, Microsoft.Extensions.Logging.ILoggerFactory loggerFactory)
        {
            loggerFactory.AddLog4Net();
            ....
        }

Use this method to set margin in dp

private void setMargins (View view, int left, int top, int right, int bottom) {
    if (view.getLayoutParams() instanceof ViewGroup.MarginLayoutParams) {
        ViewGroup.MarginLayoutParams p = (ViewGroup.MarginLayoutParams) view.getLayoutParams();

        final float scale = getBaseContext().getResources().getDisplayMetrics().density;
        // convert the DP into pixel
        int l =  (int)(left * scale + 0.5f);
        int r =  (int)(right * scale + 0.5f);
        int t =  (int)(top * scale + 0.5f);
        int b =  (int)(bottom * scale + 0.5f);

        p.setMargins(l, t, r, b);
        view.requestLayout();
    }
}

call the method :

setMargins(linearLayout,5,0,5,0);

Well, according to the mysql_real_escape_string function reference page: "mysql_real_escape_string() calls MySQL's library function mysql_real_escape_string, which escapes the following characters: \x00, \n, \r, \, ', " and \x1a."

With that in mind, then the function given in the second link you posted should do exactly what you need:

function mres($value)
{
    $search = array("\\",  "\x00", "\n",  "\r",  "'",  '"', "\x1a");
    $replace = array("\\\\","\\0","\\n", "\\r", "\'", '\"', "\\Z");

    return str_replace($search, $replace, $value);
}

I got the resources on C# (Desktop WPF W/ .NET Framework 4.8) using the code below

{DefaultNamespace}.Properties.Resources.{ResourceName}

Fixed by moving the view modifiers to onPostExecute so the fixed code is :

public class Soirees extends ListActivity {
    private List<Message> messages;
    private TextView tvSorties;

    //private MyProgressDialog dialog;
    @Override
    public void onCreate(Bundle icicle) {

        super.onCreate(icicle);

        setContentView(R.layout.sorties);

        tvSorties=(TextView)findViewById(R.id.TVTitle);
        tvSorties.setText("Programme des soirées");

        new ProgressTask(Soirees.this).execute();


   }


    private class ProgressTask extends AsyncTask<String, Void, Boolean> {
        private ProgressDialog dialog;
        List<Message> titles;
        private ListActivity activity;
        //private List<Message> messages;
        public ProgressTask(ListActivity activity) {
            this.activity = activity;
            context = activity;
            dialog = new ProgressDialog(context);
        }



        /** progress dialog to show user that the backup is processing. */

        /** application context. */
        private Context context;

        protected void onPreExecute() {
            this.dialog.setMessage("Progress start");
            this.dialog.show();
        }

            @Override
        protected void onPostExecute(final Boolean success) {
                List<Message> titles = new ArrayList<Message>(messages.size());
                for (Message msg : messages){
                    titles.add(msg);
                }
                MessageListAdapter adapter = new MessageListAdapter(activity, titles);
                activity.setListAdapter(adapter);
                adapter.notifyDataSetChanged();

                if (dialog.isShowing()) {
                dialog.dismiss();
            }

            if (success) {
                Toast.makeText(context, "OK", Toast.LENGTH_LONG).show();
            } else {
                Toast.makeText(context, "Error", Toast.LENGTH_LONG).show();
            }
        }

@Vladimir, thx your code was very helpful.

Suppose you want to write that in the same file, you can do as follows:

Set-Content -Path "C:\temp\Newtext.txt" -Value (get-content -Path "c:\Temp\Newtext.txt" | Select-String -Pattern 'H\|159' -NotMatch)

Just iterate the old-fashion way, because you need explicit index handling:

List myList = ...
...
int length = myList.size();
for(int i = 0; i < length; i++) {
   String s = myList.get(i);
   // add items here, if you want to
}

If you just want to change the port because it is already in use. Follow the following steps.

In Visual studio

1. Right-click on Project Node and Unload Project
2. Right-click on Project Node and Edit .csproj file.
3. Search for the following tags and remove them

<DevelopmentServerPort>62140</DevelopmentServerPort>
<DevelopmentServerVPath></DevelopmentServerVPath>
<IISUrl>http://localhost:62116/</IISUrl>

4. press Ctrl + S to save the document
5. Right-click on Project Node and load Project

It will work by selecting another port randomly.

Looks like the mysql server is not started.

Look to the official documentation of MySQL how you can start a service under windows.

Install the server as a service using this command: C:> "C:\Program Files\MySQL\MySQL Server 5.5\bin\mysqld" --install

(Following is a late but complete answer)

FileReader methods support

FileReader.readAsBinaryString() is deprecated. Don't use it! It's no longer in the W3C File API working draft:

void abort();
void readAsArrayBuffer(Blob blob);
void readAsText(Blob blob, optional DOMString encoding);
void readAsDataURL(Blob blob);

NB: Note that File is a kind of extended Blob structure.

Mozilla still implements readAsBinaryString() and describes it in MDN FileApi documentation:

void abort();
void readAsArrayBuffer(in Blob blob); Requires Gecko 7.0
void readAsBinaryString(in Blob blob);
void readAsDataURL(in Blob file);
void readAsText(in Blob blob, [optional] in DOMString encoding);

The reason behind readAsBinaryString() deprecation is in my opinion the following: the standard for JavaScript strings are DOMString which only accept UTF-8 characters, NOT random binary data. So don't use readAsBinaryString(), that's not safe and ECMAScript-compliant at all.

We know that JavaScript strings are not supposed to store binary data but Mozilla in some sort can. That's dangerous in my opinion. Blob and typed arrays (ArrayBuffer and the not-yet-implemented but not necessary StringView) were invented for one purpose: allow the use of pure binary data, without UTF-8 strings restrictions.

XMLHttpRequest upload support

XMLHttpRequest.send() has the following invocations options:

void send();
void send(ArrayBuffer data);
void send(Blob data);
void send(Document data);
void send(DOMString? data);
void send(FormData data);

XMLHttpRequest.sendAsBinary() has the following invocations options:

void sendAsBinary(   in DOMString body );

sendAsBinary() is NOT a standard and may not be supported in Chrome.

Solutions

So you have several options:

1. send() the FileReader.result of FileReader.readAsArrayBuffer ( fileObject ). It is more complicated to manipulate (you'll have to make a separate send() for it) but it's the RECOMMENDED APPROACH.
2. send() the FileReader.result of FileReader.readAsDataURL( fileObject ). It generates useless overhead and compression latency, requires a decompression step on the server-side BUT it's easy to manipulate as a string in Javascript.
3. Being non-standard and sendAsBinary() the FileReader.result of FileReader.readAsBinaryString( fileObject )

MDN states that:

The best way to send binary content (like in files upload) is using ArrayBuffers or Blobs in conjuncton with the send() method. However, if you want to send a stringifiable raw data, use the sendAsBinary() method instead, or the StringView (Non native) typed arrays superclass.

Make sure you remove any java.exe, javaw.exe and javaws.exe from your system.

• if you have an x32 system (Win XP 32 bits) Windows\System32 folder

• if you have an x64 system (Win 7 64 bits) also do the same under Windows\SysWOW64 folder

This is the first example in the manual page for mysql_query:

$result = mysql_query('SELECT * WHERE 1=1');
if (!$result) {
    die('Invalid query: ' . mysql_error());
}

If you wish to use something other than die, then I'd suggest trigger_error.

If you have several versions of Python installed, /usr/bin/env will ensure the interpreter used is the first one on your environment's $PATH. The alternative would be to hardcode something like #!/usr/bin/python; that's ok, but less flexible.

In Unix, an executable file that's meant to be interpreted can indicate what interpreter to use by having a #! at the start of the first line, followed by the interpreter (and any flags it may need).

If you're talking about other platforms, of course, this rule does not apply (but that "shebang line" does no harm, and will help if you ever copy that script to a platform with a Unix base, such as Linux, Mac, etc).

Sometimes the easiest way to fix this issue is to make a new branch from the place where you know the code is good. Then you can leave the errant branch history alone in case you need to cherry-pick other commits from it later. This also ensures you did not lose any commit history.

From your local errant branch:

git log

copy the commit hash that you wanted the branch to be at and exit the git log

git checkout theHashYouJustCopied
git checkout -b your_new_awesome_branch

Now you have a new branch just the way you want it.

If you also needed to keep a specific commit from the errant branch that is not on your new branch, you can just cherry-pick that specific commit you need:

git checkout the_errant_branch
git log

Copy the commit hash of the one commit you need to pull into the good branch and exit the git log.

git checkout your_new_awesome_branch
git cherry-pick theHashYouJustCopied

Pat yourself on the back.

The simple way is:

function Foo(a) {
  var that=this;

  function privateMethod() { .. }

  // public methods
  that.add = function(b) {
    return a + b;
  };
  that.avg = function(b) {
    return that.add(b) / 2; // calling another public method
  };
}

var x = new Foo(10);
alert(x.add(2)); // 12
alert(x.avg(20)); // 15

The reason for that is that this can be bound to something else if you give a method as an event handler, so you save the value during instantiation and use it later.

Edit: it's definitely not the best way, just a simple way. I'm waiting for good answers too!

That's true, element in Set are not ordered, by definition of the Set Collection. So they can't be access by an index.

But why don't we have a get(object) method, not by providing the index as parameter, but an object that is equal to the one we are looking for? By this way, we can access the data of the element inside the Set, just by knowing its attributes used by the equal method.

HTTP_CLIENT_IP is the most reliable way of getting the user's IP address. Next is HTTP_X_FORWARDED_FOR, followed by REMOTE_ADDR. Check all three, in that order, assuming that the first one that is set (isset($_SERVER['HTTP_CLIENT_IP']) returns true if that variable is set) is correct. You can independently check if the user is using a proxy using various methods. Check this out.

System wide C++ change on Ubuntu:

sudo apt-get install clang
sudo update-alternatives --config c++

Will print something like this:

  Selection    Path              Priority   Status
------------------------------------------------------------
* 0            /usr/bin/g++       20        auto mode
  1            /usr/bin/clang++   10        manual mode
  2            /usr/bin/g++       20        manual mode

Then just select clang++.

In addition to qqplots and the Shapiro-Wilk test, the following methods may be useful.

Qualitative:

• histogram compared to the normal
• cdf compared to the normal
• ggdensity plot
• ggqqplot

Quantitative:

• nortest package normality tests
• normtest package normality tests

The qualitive methods can be produced using the following in R:

library("ggpubr")
library("car")

h <- hist(data, breaks = 10, density = 10, col = "darkgray") 
xfit <- seq(min(data), max(data), length = 40) 
yfit <- dnorm(xfit, mean = mean(data), sd = sd(data)) 
yfit <- yfit * diff(h$mids[1:2]) * length(data) 
lines(xfit, yfit, col = "black", lwd = 2)

plot(ecdf(data), main="CDF")
lines(ecdf(rnorm(10000)),col="red")

ggdensity(data)

ggqqplot(data)

A word of caution - don't blindly apply tests. Having a solid understanding of stats will help you understand when to use which tests and the importance of assumptions in hypothesis testing.

Using jQuery.post

$.post(
  "http://theurl.com",
  { key1: "value1", key2: "value2" },
  function(data) {
    alert("Response: " + data);
  }
);

Obviously, the standard library provided operator does not know what to do with your user defined type mystruct. It only works for predefined data types. To be able to use it for your own data type, You need to overload operator << to take your user defined data type.

I would recommend this (just found via search):

1. http://lunapic.com/editor/?action=load
2. Browse for image to upload OR enter URL of the file (below the image)
   http://i.stack.imgur.com/2gQWg.png
3. Edit menu/Transparent (last one)
4. Click on the red area
5. Behold :) below is your image, it's just white triangle with transparency...
   [dragging the image around in your browser for visibility,
   the gray background and the border is not part of the image]
   
6. File menu/Save Image
   GIF/PNG/ICO image file formats support transparency, JPG doesn't!

One of the elements to consider as you design your interface is on what event (when A takes place, B happens...) does the new checkbox end up being added?

Let's say there is a button next to the text box. When the button is clicked the value of the textbox is turned into a new checkbox. Our markup could resemble the following...

<div id="checkboxes">
    <input type="checkbox" /> Some label<br />
    <input type="checkbox" /> Some other label<br />
</div>

<input type="text" id="newCheckText" /> <button id="addCheckbox">Add Checkbox</button>

Based on this markup your jquery could bind to the click event of the button and manipulate the DOM.

$('#addCheckbox').click(function() {
    var text = $('#newCheckText').val();
    $('#checkboxes').append('<input type="checkbox" /> ' + text + '<br />');
});

string s2 = s1.Replace(",", ",\r\n");

I use this JS snippet code :

First of all, I reach all the classes then according to index of my target class, I set className = "".

Target = document.getElementsByClassName("yourClass")[1];
Target.className="";

Add style pointer-events:none; this working fine

<iframe style="pointer-events:none;" src=""></iframe>

You can use a different approach such as writing a reverse proxy server with nodejs to proxy both apache and all other nodejs apps.

First you need to make apache run on a different port other than port 80. ex: port 8080

Then you can write a reverse proxy script with nodejs as:

var proxy = require('redbird')({port: 80, xfwd: false);

proxy.register("mydomain.me/blog", "http://mydomain.me:8080/blog");
proxy.register("mydomain.me", "http://mydomain.me:3000");

Following article describes the whole process of making this.

RUN APACHE WITH NODE JS REVERSE PROXY – USING REDBIRD

echo. Enough said.

If you need it in a single line, use the &. For example,

echo Line 1 & echo. & echo line 3

would output as:

Line 1

line 3

Now, say you want something a bit fancier, ...

set n=^&echo.
echo hello %n% world

Outputs

hello
world

Then just throw in a %n% whenever you want a new line in an echo statement. This is more close to your \n used in various languages.

Breakdown

set n= sets the variable n equal to:

^ Nulls out the next symbol to follow:

& Means to do another command on the same line. We don't care about errorlevel(its an echo statement for crying out loud), so no && is needed.

echo. Continues the echo statement.

All of this works because you can actually create variables that are code, and use them inside of other commands. It is sort of like a ghetto function, since batch is not exactly the most advanced of shell scripting languages. This only works because batch's poor usage of variables, not designating between ints, chars, floats, strings, etc naturally.

If you are crafty, you could get this to work with other things. For example, using it to echo a tab

set t=^&echo.     ::there are spaces up to the double colon

use position:fixed instead of position:absolute

The first one is relative to your screen window. (not affected by scrolling)

The second one is relative to the page. (affected by scrolling)

Note : IE6 doesn't support position:fixed.

Something like this worked for me (references columns C and D from the row 8 till the end of the columns, in Excel 2013 if relevant):

=SUMIFS(INDIRECT(ADDRESS(ROW(D$8), COLUMN())&":"&ADDRESS(ROWS($C:$C), COLUMN())),INDIRECT("C$8:C"&ROWS($C:$C)),$C$2)

I have ended up using ABCPdf from webSupergoo. It works really well and for about $350 it has saved me hours and hours based on your comments above. Thanks again Daniel and Bratch for your comments.

print_r() is mostly for debugging. If you want to print it in that format, loop through the array, and print the elements out.

foreach($data as $d){
  foreach($d as $v){
    echo $v."\n";
  }
}

This answer is an alternative approach for specific circumstances. I needed a set of bitmask constants based on attribute sub-values (cases where an attribute value is an array or list of values). It encompasses the equivalent of several overlapping enums.

I created a class to both store and generate the bitmask values. I can then use the pseudo-constant bitmask values this way to test, for example, if green is present in an RGB value:

if (value & Ez.G) {...}

In my code I create only one instance of this class. There doesn't seem to be a clean way to do this without instantiating at least one instance of the class. Here is the class declaration and bitmask value generation code:

class Ez {
constructor() {
    let rgba = ["R", "G", "B", "A"];
    let rgbm = rgba.slice();
    rgbm.push("M");              // for feColorMatrix values attribute
    this.createValues(rgba);
    this.createValues(["H", "S", "L"]);
    this.createValues([rgba, rgbm]);
    this.createValues([attX, attY, attW, attH]);
}
createValues(a) {                // a for array
    let i, j;
    if (isA(a[0])) {             // max 2 dimensions
        let k = 1;
        for (i of a[0]) {
            for (j of a[1]) {
                this[i + j] = k;
                k *= 2;
            }
        }
    }
    else {                       // 1D array is simple loop
        for (i = 0, j = 1; i < a.length; i++, j *= 2)
            this[a[i]] = j;
   }
}

The 2D array is for the SVG feColorMatrix values attribute, which is a 4x5 matrix of RGBA by RGBAM, where M is a multiplier. The resulting Ez properties are Ez.RR, Ez.RG, etc.

A very important place where it is REQUIRED to use the key => value pair in foreach loop is to be mentioned. Suppose you would want to add a new/sub-element to an existing item (in another key) in the $features array. You should do the following:

foreach($features as $key => $feature) {
    $features[$key]['new_key'] = 'new value';  
} 

Instead of this:

foreach($features as $feature) {
    $feature['new_key'] = 'new value';  
} 

The big difference here is that, in the first case you are accessing the array's sub-value via the main array itself with a key to the element which is currently being pointed to by the array pointer.

While in the second (which doesn't work for this purpose) you are assigning the sub-value in the array to a temporary variable $feature which is unset after each loop iteration.

Use the reset function, which is available on the form element.

var form = document.getElementById("myForm");
form.reset();

This arstechnica article describes the basic steps:

Start by visiting the program portal and make sure that your developer certificate is up to date. It expires every six months and, if you haven't requested that a new one be issued, you cannot submit software to App Store. For most people experiencing the "pink upload of doom," though, their certificates are already valid. What next?

Open your Xcode project and check that you've set the active SDK to one of the device choices, like Device - 2.2. Accidentally leaving the build settings to Simulator can be a big reason for the pink rejection. And that happens more often than many developers would care to admit.

Next, make sure that you've chosen a build configuration that uses your distribution (not your developer) certificate. Check this by double-clicking on your target in the Groups & Files column on the left of the project window. The Target Info window will open. Click the Build tab and review your Code Signing Identity. It should be iPhone Distribution: followed by your name or company name.

You may also want to confirm your application identifier in the Properties tab. Most likely, you'll have set the identifier properly when debugging with your developer certificate, but it never hurts to check.

The top-left of your project window also confirms your settings and configuration. It should read something like "Device - 2.2 | Distribution". This shows you the active SDK and configuration.

If your settings are correct but you still aren't getting that upload finished properly, clean your builds. Choose Build > Clean (Command-Shift-K) and click Clean. Alternatively, you can manually trash the build folder in your Project from Finder. Once you've cleaned, build again fresh.

If this does not produce an app that when zipped properly loads to iTunes Connect, quit and relaunch Xcode. I'm not kidding. This one simple trick solves more signing problems and "pink rejections of doom" than any other solution already mentioned.

Using git 2.9 (precisely 2.9.2.windows.1) git reset HEAD^ prompts for more; not sure what is expected input here. Please refer below screenshot

Found other solution git reset HEAD~#numberOfCommits using which we can choose to select number of local commits you want to reset by keeping your changes intact. Hence, we get an opportunity to throw away all local commits as well as limited number of local commits.

Refer below screenshots showing git reset HEAD~1 in action:

You do not need any client side code if doing this is ASP.NET. The example below is a boostrap input box with a search button with an fontawesome icon.

You will see that in place of using a regular < div > tag with a class of "input-group" I have used a asp:Panel. The DefaultButton property set to the id of my button, does the trick.

In example below, after typing something in the input textbox, you just hit enter and that will result in a submit.

<asp:Panel DefaultButton="btnblogsearch" runat="server" CssClass="input-group blogsearch">
<asp:TextBox ID="txtSearchWords" CssClass="form-control" runat="server" Width="100%" Placeholder="Search for..."></asp:TextBox>
<span class="input-group-btn">
    <asp:LinkButton ID="btnblogsearch" runat="server" CssClass="btn btn-default"><i class="fa fa-search"></i></asp:LinkButton>
</span></asp:Panel>

The correct answer for Java is use a Set. If you already have a List<Customer> and want to de duplicate it

Set<Customer> s = new HashSet<Customer>(listCustomer);

Otherise just use a Set implemenation HashSet, TreeSet directly and skip the List construction phase.

You will need to override hashCode() and equals() on your domain classes that are put in the Set as well to make sure that the behavior you want actually what you get. equals() can be as simple as comparing unique ids of the objects to as complex as comparing every field. hashCode() can be as simple as returning the hashCode() of the unique id' String representation or the hashCode().

I've developed the interpy package, that enables string interpolation in Python.

Just install it via pip install interpy. And then, add the line # coding: interpy at the beginning of your files!

Example:

#!/usr/bin/env python
# coding: interpy

name = "Spongebob Squarepants"
print "Who lives in a Pineapple under the sea? \n#{name}."

A nice and simple option that worked for me was:

<a href="javascript: false" onClick={this.handlerName}>Click Me</a>

What you ask for is the join operation. With the how argument, you can define how unique indices are handled. Here, some article, which looks helpful concerning this point. In the example below, I left out cosmetics (like renaming columns) for simplicity.

Code

import numpy as np
import pandas as pd
df1 = pd.DataFrame(np.random.randn(5,3), index=pd.date_range('01/02/2014',periods=5,freq='D'), columns=['a','b','c'] )
df2 = pd.DataFrame(np.random.randn(8,3), index=pd.date_range('01/01/2014',periods=8,freq='D'), columns=['a','b','c'] )

df3 = df1.join(df2, how='outer', lsuffix='_df1', rsuffix='_df2')
print(df3)

Output

               a_df1     b_df1     c_df1     a_df2     b_df2     c_df2

First of all, never use a for in loop to enumerate over an array. Never. Use good old for(var i = 0; i<arr.length; i++).

The reason behind this is the following: each object in JavaScript has a special field called prototype. Everything you add to that field is going to be accessible on every object of that type. Suppose you want all arrays to have a cool new function called filter_0 that will filter zeroes out.

Array.prototype.filter_0 = function() {
    var res = [];
    for (var i = 0; i < this.length; i++) {
        if (this[i] != 0) {
            res.push(this[i]);
        }
    }
    return res;
};

console.log([0, 5, 0, 3, 0, 1, 0].filter_0());
//prints [5,3,1]

This is a standard way to extend objects and add new methods. Lots of libraries do this. However, let's look at how for in works now:

var listeners = ["a", "b", "c"];
for (o in listeners) {
    console.log(o);
}
//prints:
//  0
//  1
//  2
//  filter_0

Do you see? It suddenly thinks filter_0 is another array index. Of course, it is not really a numeric index, but for in enumerates through object fields, not just numeric indexes. So we're now enumerating through every numeric index and filter_0. But filter_0 is not a field of any particular array object, every array object has this property now.

Luckily, all objects have a hasOwnProperty method, which checks if this field really belongs to the object itself or if it is simply inherited from the prototype chain and thus belongs to all the objects of that type.

for (o in listeners) {
    if (listeners.hasOwnProperty(o)) {
       console.log(o);
    }
}
 //prints:
 //  0
 //  1
 //  2

Note, that although this code works as expected for arrays, you should never, never, use for in and for each in for arrays. Remember that for in enumerates the fields of an object, not array indexes or values.

var listeners = ["a", "b", "c"];
listeners.happy = "Happy debugging";

for (o in listeners) {
    if (listeners.hasOwnProperty(o)) {
       console.log(o);
    }
}

 //prints:
 //  0
 //  1
 //  2
 //  happy

Solution in ES6/TypeScript:

let d = new Date;
console.log(d, [`${d.getFullYear()}`, `0${d.getMonth()}`.substr(-2), `0${d.getDate()}`.substr(-2)].join("-"));

It is the equivalent to \n -> LF (Line Feed).

Sometimes it is used in HTML and JavaScript. Otherwise in .NET environments, use Environment.NewLine.

Best solution would be to convert existing databases BEFORE upgrading to newer version/s of Access. Surely Microsoft should be warning users about this problem when upgrades are about to be installed.

You can but you probably shouldn't:

try:
    do_something()
except:
    print "Caught it!"

However, this will also catch exceptions like KeyboardInterrupt and you usually don't want that, do you? Unless you re-raise the exception right away - see the following example from the docs:

try:
    f = open('myfile.txt')
    s = f.readline()
    i = int(s.strip())
except IOError as (errno, strerror):
    print "I/O error({0}): {1}".format(errno, strerror)
except ValueError:
    print "Could not convert data to an integer."
except:
    print "Unexpected error:", sys.exc_info()[0]
    raise

You may try this way. just use a function to get your object

def get_object(self, id):
    try:
        return UniversityDetails.objects.get(email__exact=email)
    except UniversityDetails.DoesNotExist:
        return False

Firstly, as Etienne says, float in C# is Single. It is just the C# keyword for that data type.

So you can definitely do this:

float f = 13.5f;
string s = f.ToString("R");

Secondly, you have referred a couple of times to the number's "format"; numbers don't have formats, they only have values. Strings have formats. Which makes me wonder: what is this thing you have that has a format but is not a string? The closest thing I can think of would be decimal, which does maintain its own precision; however, calling simply decimal.ToString should have the effect you want in that case.

How about including some example code so we can see exactly what you're doing, and why it isn't achieving what you want?

Best way to locate anchor elements is to use link=Re-Call:

selenium.click("link=Re-Call");

It will work..

I had the same problem and it appears when I updated my sdk packages and added sdk 22 I removed all wear packages from sdk 22 as well as other sdks but problem wasn't resolved I Updated all of my sdk packages again from sdk manager then problem solved and error gone.

I think there's been few bugs with eclipse and android wear packages which are fixed in new updates available in sdk manager

Just do:

sudo apt-get install python-lxml

For Python 2 (e.g., required by Inkscape):

sudo apt-get install python2-lxml

If you are planning to install from source, then albertov's answer will help. But unless there is a reason, don't, just install it from the repository.

The below is based on Todd Owen's answer. That solution has the problem that if the replacements contain characters that have special meaning in regular expressions, you can get unexpected results. I also wanted to be able to optionally do a case-insensitive search. Here is what I came up with:

/**
 * Performs simultaneous search/replace of multiple strings. Case Sensitive!
 */
public String replaceMultiple(String target, Map<String, String> replacements) {
  return replaceMultiple(target, replacements, true);
}

/**
 * Performs simultaneous search/replace of multiple strings.
 * 
 * @param target        string to perform replacements on.
 * @param replacements  map where key represents value to search for, and value represents replacem
 * @param caseSensitive whether or not the search is case-sensitive.
 * @return replaced string
 */
public String replaceMultiple(String target, Map<String, String> replacements, boolean caseSensitive) {
  if(target == null || "".equals(target) || replacements == null || replacements.size() == 0)
    return target;

  //if we are doing case-insensitive replacements, we need to make the map case-insensitive--make a new map with all-lower-case keys
  if(!caseSensitive) {
    Map<String, String> altReplacements = new HashMap<String, String>(replacements.size());
    for(String key : replacements.keySet())
      altReplacements.put(key.toLowerCase(), replacements.get(key));

    replacements = altReplacements;
  }

  StringBuilder patternString = new StringBuilder();
  if(!caseSensitive)
    patternString.append("(?i)");

  patternString.append('(');
  boolean first = true;
  for(String key : replacements.keySet()) {
    if(first)
      first = false;
    else
      patternString.append('|');

    patternString.append(Pattern.quote(key));
  }
  patternString.append(')');

  Pattern pattern = Pattern.compile(patternString.toString());
  Matcher matcher = pattern.matcher(target);

  StringBuffer res = new StringBuffer();
  while(matcher.find()) {
    String match = matcher.group(1);
    if(!caseSensitive)
      match = match.toLowerCase();
    matcher.appendReplacement(res, replacements.get(match));
  }
  matcher.appendTail(res);

  return res.toString();
}

Here are my unit test cases:

@Test
public void replaceMultipleTest() {
  assertNull(ExtStringUtils.replaceMultiple(null, null));
  assertNull(ExtStringUtils.replaceMultiple(null, Collections.<String, String>emptyMap()));
  assertEquals("", ExtStringUtils.replaceMultiple("", null));
  assertEquals("", ExtStringUtils.replaceMultiple("", Collections.<String, String>emptyMap()));

  assertEquals("folks, we are not sane anymore. with me, i promise you, we will burn in flames", ExtStringUtils.replaceMultiple("folks, we are not winning anymore. with me, i promise you, we will win big league", makeMap("win big league", "burn in flames", "winning", "sane")));

  assertEquals("bcaacbbcaacb", ExtStringUtils.replaceMultiple("abccbaabccba", makeMap("a", "b", "b", "c", "c", "a")));
  assertEquals("bcaCBAbcCCBb", ExtStringUtils.replaceMultiple("abcCBAabCCBa", makeMap("a", "b", "b", "c", "c", "a")));
  assertEquals("bcaacbbcaacb", ExtStringUtils.replaceMultiple("abcCBAabCCBa", makeMap("a", "b", "b", "c", "c", "a"), false));

  assertEquals("c colon  backslash temp backslash  star  dot  star ", ExtStringUtils.replaceMultiple("c:\\temp\\*.*", makeMap(".", " dot ", ":", " colon ", "\\", " backslash ", "*", " star "), false));
}

private Map<String, String> makeMap(String ... vals) {
  Map<String, String> map = new HashMap<String, String>(vals.length / 2);
  for(int i = 1; i < vals.length; i+= 2)
    map.put(vals[i-1], vals[i]);
  return map;
}

JQuery has a way to pass parameters from HTML to javascript:

Put this in the myhtml.html file:

<!-- Import javascript -->
<script src="//code.jquery.com/jquery-1.11.2.min.js"></script>
<!-- Invoke a different javascript file called subscript.js -->
<script id="myscript" src="subscript.js" video_filename="foobar.mp4">/script>

In the same directory make a subscript.js file and put this in there:

//Use jquery to look up the tag with the id of 'myscript' above.  Get 
//the attribute called video_filename, stuff it into variable filename.
var filename = $('#myscript').attr("video_filename");

//print filename out to screen.
document.write(filename);

Analyze Result:

Loading the myhtml.html page has 'foobar.mp4' print to screen. The variable called video_filename was passed from html to javascript. Javascript printed it to screen, and it appeared as embedded into the html in the parent.

jsfiddle proof that the above works:

Use time

Let's say you have the initial dates as strings like these:
date1 = "31/12/2015"
date2 = "01/01/2016"

You can do the following:
newdate1 = time.strptime(date1, "%d/%m/%Y") and newdate2 = time.strptime(date2, "%d/%m/%Y") to convert them to python's date format. Then, the comparison is obvious:

newdate1 > newdate2 will return False
newdate1 < newdate2 will return True

# Use slicing to extract those parts of the original string to be kept
s = s[:position] + replacement + s[position+length_of_replaced:]

# Example: replace 'sat' with 'slept'
text = "The cat sat on the mat"
text = text[:8] + "slept" + text[11:]

I/P : The cat sat on the mat

O/P : The cat slept on the mat

The &nKByte creates a temporary value, which cannot be bound to a reference to non-const.

You could change void test(float *&x) to void test(float * const &x) or you could just drop the pointer altogether and use void test(float &x); /*...*/ test(nKByte);.

If working with integers, one way of rounding up is to take advantage of the fact that // rounds down: Just do the division on the negative number, then negate the answer. No import, floating point, or conditional needed.

rounded_up = -(-numerator // denominator)

For example:

>>> print(-(-101 // 5))
21

Any one got the same issue it's related to a conflict between brew and npm Please check this solution https://gist.github.com/DanHerbert/9520689

To automate this, you can use any script or app that can send a string to a socket. I personally like nc (netcat) under cygwin. As I said before, I use it like this:

$ echo kill | nc -w 2 localhost 5554

(that means to send "kill" string to the port 5554 on localhost, and terminate netcat after 2 seconds.)

Yes you can. The abstract class used in java signifies that you can't create an object of the class. And an abstract method the subclasses have to provide an implementation for that method.

So you can easily define an abstract class without any abstract method.

As for Example :

public abstract class AbstractClass{

    public String nonAbstractMethodOne(String param1,String param2){
        String param = param1 + param2;
        return param;
    }

    public static void nonAbstractMethodTwo(String param){
        System.out.println("Value of param is "+param);
    }
}

This is fine.

Use breakpoint mixins like this:

.something {
    padding: 5px;
    @include media-breakpoint-up(sm) { 
        padding: 20px;
    }
    @include media-breakpoint-up(md) { 
        padding: 40px;
    }
}

If you are dealing with a web service call using the Axis framework, there is a much simpler answer. If all want is for your client to be able to call the SSL web service and ignore SSL certificate errors, just put this statement before you invoke any web services:

System.setProperty("axis.socketSecureFactory", "org.apache.axis.components.net.SunFakeTrustSocketFactory");

The usual disclaimers about this being a Very Bad Thing to do in a production environment apply.

I found this at the Axis wiki.

Both old and accepted, however, I'll just leave this here:

function dump(){
    echo (php_sapi_name() !== 'cli') ? '<pre>' : '';
    foreach(func_get_args() as $arg){
        echo preg_replace('#\n{2,}#', "\n", print_r($arg, true));
    }
    echo (php_sapi_name() !== 'cli') ? '</pre>' : '';
}

Takes an arbitrary number of arguments, and wraps each in <pre> for CGI requests. In CLI requests it skips the <pre> tag generation for clean output.

dump(array('foo'), array('bar', 'zip'));
/*
CGI request                          CLI request

<pre>                                Array
Array                                (
(                                        [0] => foo
    [0] => foo                       )
)                                    Array
</pre>                               (
<pre>                                    [0] => bar
Array                                    [1] => zip
(                                    )
    [0] => bar
    [0] => zip
)
</pre>

You cannot ... yet. But this is an alternative, think like a docker-composer.yml generator:

https://gist.github.com/Vad1mo/9ab63f28239515d4dafd

Basically a shell script that will replace your variables. Also you can use Grunt task to build your docker compose file at the end of your CI process.

It might not look that clean but you can have your Dockerfile (conditional) as follow:

FROM centos:7
ARG arg
RUN if [[ -z "$arg" ]] ; then echo Argument not provided ; else echo Argument is $arg ; fi

and then build the image as:

docker build -t my_docker . --build-arg arg=45

or

docker build -t my_docker .

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

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

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

I'd make both the input and label elements display: block , and then split the name label & input, and the email label & input into div's and float them next to each other.

input, label {_x000D_
    display:block;_x000D_
}

<form name="message" method="post">_x000D_
    <section>_x000D_
_x000D_
  <div style="float:left;margin-right:20px;">_x000D_
    <label for="name">Name</label>_x000D_
    <input id="name" type="text" value="" name="name">_x000D_
  </div>_x000D_
_x000D_
  <div style="float:left;">_x000D_
    <label for="email">Email</label>_x000D_
    <input id="email" type="text" value="" name="email">_x000D_
  </div>_x000D_
_x000D_
  <br style="clear:both;" />_x000D_
_x000D_
    </section>_x000D_
_x000D_
    <section>_x000D_
_x000D_
    <label for="subject">Subject</label>_x000D_
    <input id="subject" type="text" value="" name="subject">_x000D_
    <label for="message">Message</label>_x000D_
    <input id="message" type="text" value="" name="message">_x000D_
_x000D_
    </section>_x000D_
</form>

You can parse the text as a string, which creates an Element, and create an ElementTree using that Element.

import xml.etree.ElementTree as ET
tree = ET.ElementTree(ET.fromstring(xmlstring))

I just came across this issue and the documentation, while complete, is not very straightforward on the difference in usage between the parse() and fromstring() methods.

If you are looking for a difference expressed as a combination of years, months, and days, I would suggest this function:

function interval(date1, date2) {_x000D_
    if (date1 > date2) { // swap_x000D_
        var result = interval(date2, date1);_x000D_
        result.years  = -result.years;_x000D_
        result.months = -result.months;_x000D_
        result.days   = -result.days;_x000D_
        result.hours  = -result.hours;_x000D_
        return result;_x000D_
    }_x000D_
    result = {_x000D_
        years:  date2.getYear()  - date1.getYear(),_x000D_
        months: date2.getMonth() - date1.getMonth(),_x000D_
        days:   date2.getDate()  - date1.getDate(),_x000D_
        hours:  date2.getHours() - date1.getHours()_x000D_
    };_x000D_
    if (result.hours < 0) {_x000D_
        result.days--;_x000D_
        result.hours += 24;_x000D_
    }_x000D_
    if (result.days < 0) {_x000D_
        result.months--;_x000D_
        // days = days left in date1's month, _x000D_
        //   plus days that have passed in date2's month_x000D_
        var copy1 = new Date(date1.getTime());_x000D_
        copy1.setDate(32);_x000D_
        result.days = 32-date1.getDate()-copy1.getDate()+date2.getDate();_x000D_
    }_x000D_
    if (result.months < 0) {_x000D_
        result.years--;_x000D_
        result.months+=12;_x000D_
    }_x000D_
    return result;_x000D_
}_x000D_
_x000D_
// Be aware that the month argument is zero-based (January = 0)_x000D_
var date1 = new Date(2015, 4-1, 6);_x000D_
var date2 = new Date(2015, 5-1, 9);_x000D_
_x000D_
document.write(JSON.stringify(interval(date1, date2)));

This solution will treat leap years (29 February) and month length differences in a way we would naturally do (I think).

So for example, the interval between 28 February 2015 and 28 March 2015 will be considered exactly one month, not 28 days. If both those days are in 2016, the difference will still be exactly one month, not 29 days.

Dates with exactly the same month and day, but different year, will always have a difference of an exact number of years. So the difference between 2015-03-01 and 2016-03-01 will be exactly 1 year, not 1 year and 1 day (because of counting 365 days as 1 year).

You can create your own animations. Place animation XML files in res > anim

enter_from_left.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
     android:shareInterpolator="false">

      android:duration="@android:integer/config_mediumAnimTime"/>
</set>

      android:duration="@android:integer/config_mediumAnimTime"/>
</set>

exit_to_right.xml

<?xml version="1.0" encoding="utf-8"?>

     android:fromYDelta="0%" android:toYDelta="0%"
     android:duration="@android:integer/config_mediumAnimTime" />
</set>

you can change the duration to short animation time

android:duration="@android:integer/config_shortAnimTime"

or long animation time

android:duration="@android:integer/config_longAnimTime" 

USAGE (note that the order in which you call methods on the transaction matters. Add the animation before you call .replace, .commit):

FragmentTransaction transaction = supportFragmentManager.beginTransaction();
transaction.setCustomAnimations(R.anim.enter_from_right, R.anim.exit_to_left, R.anim.enter_from_left, R.anim.exit_to_right);
transaction.replace(R.id.content_frame, fragment);
transaction.addToBackStack(null);
transaction.commit();

These answers are a bit dated. Therefore I give you:

hash = JSON.parse string

Rails should automagically load the json module for you, so you don't need to add require 'json'.

If checkout master was the last thing you did, then the reflog entry HEAD@{1} will contain your commits (otherwise use git reflog or git log -p to find them). Use git merge HEAD@{1} to fast forward them into master.

EDIT:

As noted in the comments, Git Ready has a great article on this.

git reflog and git reflog --all will give you the commit hashes of the mis-placed commits.

Source: http://gitready.com/intermediate/2009/02/09/reflog-your-safety-net.html

Just in case some other poor sod ends up here because they are having the same issue I was: if you have multiple data sources and this is happening with the non-primary data source, then the problem might be with that config. The data source, entity manager factory, and transaction factory all need to be correctly configured, but also -- and this is what tripped me up -- MAKE SURE TO TIE THEM ALL TOGETHER! @EnableJpaRepositories (configuration class annotation) must include entityManagerFactoryRef and transactionManagerRef to pick up all the configuration!

The example in this blog finally helped me see what I was missing, which (for quick reference) were the refs here:

@EnableJpaRepositories(
    entityManagerFactoryRef = "barEntityManagerFactory",
    transactionManagerRef = "barTransactionManager",
    basePackages = "com.foobar.bar")

Hope this helps save someone else from the struggle I've endured!

Here is a solution other library free:

Path sourceFile = Paths.get("some/common/path/example/a/b/c/f1.txt");
Path targetFile = Paths.get("some/common/path/example/d/e/f2.txt"); 
Path relativePath = sourceFile.relativize(targetFile);
System.out.println(relativePath);

Outputs

..\..\..\..\d\e\f2.txt

[EDIT] actually it outputs on more ..\ because of the source is file not a directory. Correct solution for my case is:

Path sourceFile = Paths.get(new File("some/common/path/example/a/b/c/f1.txt").parent());
Path targetFile = Paths.get("some/common/path/example/d/e/f2.txt"); 
Path relativePath = sourceFile.relativize(targetFile);
System.out.println(relativePath);
