The linefeed character \n is not the line separator in certain operating systems (such as windows, where it's "\r\n") - my suggestion is that you use \r\n instead, then it'll both see the line-break with only \n and \r\n, I've never had any problems using it.

Also, you should look into using a StringBuilder instead of concatenating the String in the while-loop at BookCatalog.toString(), it is a lot more effective. For instance:

public String toString() {
        BookNode current = front;
        StringBuilder sb = new StringBuilder();
        while (current!=null){
            sb.append(current.getData().toString()+"\r\n ");
            current = current.getNext();
        }
        return sb.toString();
}

Not very Pythonic at all, but we need at least one reduce() answer, right?

def is_sorted(iterable):
    prev_or_inf = lambda prev, i: i if prev <= i else float('inf')
    return reduce(prev_or_inf, iterable, float('-inf')) < float('inf')

The accumulator variable simply stores that last-checked value, and if any value is smaller than the previous value, the accumulator is set to infinity (and thus will still be infinity at the end, since the 'previous value' will always be bigger than the current one).

A Simple Example:

layout/billing_day_dialog.xml

The easiest way (offering something near what you wrote) is to use Boost.Regex, specifically regex_replace.

std::string has built in find() and replace() methods, but they are more cumbersome to work with as they require dealing with indices and string lengths.

On modern macOS, the correct path is /Library/Java/JavaVirtualMachines.

You can also avail yourself of the command /usr/libexec/java_home, which will scan that directory for you and return a list.

<?php
 $dbhost = 'localhost:3036';
 $dbuser = 'root';
 $dbpass = 'rootpassword';

 $conn = mysql_connect($dbhost, $dbuser, $dbpass);

 if(! $conn ) {
  die('Could not connect: ' . mysql_error());
 }

 $table_name = "employee";
 $backup_file  = "/tmp/employee.sql";
 $sql = "SELECT * INTO OUTFILE '$backup_file' FROM $table_name";

 mysql_select_db('test_db');
 $retval = mysql_query( $sql, $conn );

 if(! $retval ) {
  die('Could not take data backup: ' . mysql_error());
 }

 echo "Backedup  data successfully\n";

 mysql_close($conn);
?>

The input() function returns a string which may contain a "list of numbers". You should have understood that the numbers[2] operation returns the third element of an iterable. A string is an iterable, but an iterable of characters, which isn't what you want - you want to average the numbers in the input string.

So there are two things you have to do before you can get to the averaging shown by garyprice:

1. convert the input string into something containing just the number strings (you don't want the spaces between the numbers)
2. convert each number string into an integer

Hint for step 1: you have to split the input string into non-space substrings.

Step 2 (convert string to integer) should be easy to find with google.

HTH

"{0:#b}".format(my_int)

I think your code is right. If you run the following code it converts the string '60' which is treated as varchar and it returns integer 60, if there is integer containing string in second it works.

select CONVERT(bigint,'60') as seconds 

and it returns

60

You can use tr to convert from DOS to Unix; however, you can only do this safely if CR appears in your file only as the first byte of a CRLF byte pair. This is usually the case. You then use:

tr -d '\015' <DOS-file >UNIX-file

Note that the name DOS-file is different from the name UNIX-file; if you try to use the same name twice, you will end up with no data in the file.

You can't do it the other way round (with standard 'tr').

If you know how to enter carriage return into a script (control-V, control-M to enter control-M), then:

sed 's/^M$//'     # DOS to Unix
sed 's/$/^M/'     # Unix to DOS

where the '^M' is the control-M character. You can also use the bash ANSI-C Quoting mechanism to specify the carriage return:

sed $'s/\r$//'     # DOS to Unix
sed $'s/$/\r/'     # Unix to DOS

However, if you're going to have to do this very often (more than once, roughly speaking), it is far more sensible to install the conversion programs (e.g. dos2unix and unix2dos, or perhaps dtou and utod) and use them.

If you need to process entire directories and subdirectories, you can use zip:

zip -r -ll zipfile.zip somedir/
unzip zipfile.zip

This will create a zip archive with line endings changed from CRLF to CR. unzip will then put the converted files back in place (and ask you file by file - you can answer: Yes-to-all). Credits to @vmsnomad for pointing this out.

There is no way in Selenium to read the request or response headers. You could do it by instructing your browser to connect through a proxy that records this kind of information.

Setting the User Agent in Firefox

The usual way to change the user agent for Firefox is to set the variable "general.useragent.override" in your Firefox profile. Note that this is independent from Selenium.

You can direct Selenium to use a profile different from the default one, like this:

from selenium import webdriver
profile = webdriver.FirefoxProfile()
profile.set_preference("general.useragent.override", "whatever you want")
driver = webdriver.Firefox(profile)

Setting the User Agent in Chrome

With Chrome, what you want to do is use the user-agent command line option. Again, this is not a Selenium thing. You can invoke Chrome at the command line with chrome --user-agent=foo to set the agent to the value foo.

With Selenium you set it like this:

from selenium import webdriver
from selenium.webdriver.chrome.options import Options
opts = Options()
opts.add_argument("user-agent=whatever you want")

driver = webdriver.Chrome(chrome_options=opts)

Both methods above were tested and found to work. I don't know about other browsers.

Getting the User Agent

Selenium does not have methods to query the user agent from an instance of WebDriver. Even in the case of Firefox, you cannot discover the default user agent by checking what general.useragent.override would be if not set to a custom value. (This setting does not exist before it is set to some value.)

Once the browser is started, however, you can get the user agent by executing:

agent = driver.execute_script("return navigator.userAgent")

The agent variable will contain the user agent.

Try using the code after you active the sheet:

Dim J as integer
J = ActiveSheet.UsedRange.SpecialCells(xlCellTypeLastCell).Row

If you use Cells.SpecialCells(xlCellTypeLastCell).Row only, the problem will be that the xlCellTypeLastCell information will not be updated unless one do a "Save file" action. But use UsedRange will always update the information in realtime.

Believe it or not, renaming LinqPad.exe.config to LinqPad.config solved this problem.

the fancy answer. Use std::vector and search with std::find

the simple answer

use a for loop

There are two commands, which you can use to check the version of redis

    redis-server -v

or

    redis-server --version

Your two examples look identical, which makes problems hard to diagnose. Potential problems:

1. You may need double quotes, as in sed 's/xxx/'"$PWD"'/'

2. $PWD may contain a slash, in which case you need to find a character not contained in $PWD to use as a delimiter.

To nail both issues at once, perhaps

sed 's@xxx@'"$PWD"'@'

You can use plt.grid to draw a horizontal line.

import numpy as np
from matplotlib import pyplot as plt
from scipy.interpolate import UnivariateSpline
from matplotlib.ticker import LinearLocator

# your data here
annual = np.arange(1,21,1)
l = np.random.random(20)
spl = UnivariateSpline(annual,l)
xs = np.linspace(1,21,200)

# plot your data
plt.plot(xs,spl(xs),'b')

# horizental line?
ax = plt.axes()
# three ticks:
ax.yaxis.set_major_locator(LinearLocator(3))
# plot grids only on y axis on major locations
plt.grid(True, which='major', axis='y')

# show
plt.show()

Rab's answer works great, but not for Microsoft Edge, so I added a small adaptation for Edge as well:

https://jsfiddle.net/et9borp4/

function insertAtCursor(myField, myValue) {
    //IE support
    if (document.selection) {
        myField.focus();
        sel = document.selection.createRange();
        sel.text = myValue;
    }
    // Microsoft Edge
    else if(window.navigator.userAgent.indexOf("Edge") > -1) {
      var startPos = myField.selectionStart; 
      var endPos = myField.selectionEnd; 

      myField.value = myField.value.substring(0, startPos)+ myValue 
             + myField.value.substring(endPos, myField.value.length); 

      var pos = startPos + myValue.length;
      myField.focus();
      myField.setSelectionRange(pos, pos);
    }
    //MOZILLA and others
    else if (myField.selectionStart || myField.selectionStart == '0') {
        var startPos = myField.selectionStart;
        var endPos = myField.selectionEnd;
        myField.value = myField.value.substring(0, startPos)
            + myValue
            + myField.value.substring(endPos, myField.value.length);
    } else {
        myField.value += myValue;
    }
}

Same as the answer by Dmitry Yudakov, but without an intermediate file, using process substitution:

svn commit --targets <(echo "MyFile1.txt\nMyFile2.txt\n")

The getActiveNetworkInfo() method of ConnectivityManager returns a NetworkInfo instance representing the first connected network interface it can find or null if none if the interfaces are connected. Checking if this method returns null should be enough to tell if an internet connection is available.

private boolean isNetworkAvailable() {
     ConnectivityManager connectivityManager = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
     NetworkInfo activeNetworkInfo = connectivityManager.getActiveNetworkInfo();
     return activeNetworkInfo != null; 
}

You will also need:

in your android manifest.

Edit:

Note that having an active network interface doesn't guarantee that a particular networked service is available. Networks issues, server downtime, low signal, captive portals, content filters and the like can all prevent your app from reaching a server. For instance you can't tell for sure if your app can reach Twitter until you receive a valid response from the Twitter service.

getActiveNetworkInfo() shouldn't never give null. I don't know what they were thinking when they came up with that. It should give you an object always.

On MacOS: add source ~/.bash_profile to the end of ~/.zshrc. Then this profile will be in effect when you open zsh.

I believe you need to specify "Option Infer On" for this to work.

Option Infer allows the compiler to make a guess at what is being represented by your code, thus it will guess that {"stuff"} is an array of strings. With "Option Infer Off", {"stuff"} won't have any type assigned to it, ever, and so it will always fail, without a type specifier.

Option Infer is, I think On by default in new projects, but Off by default when you migrate from earlier frameworks up to 3.5.

Opinion incoming:

Also, you mention that you've got "Option Explicit Off". Please don't do this.

Setting "Option Explicit Off" means that you don't ever have to declare variables. This means that the following code will silently and invisibly create the variable "Y":

Dim X as Integer
Y = 3

This is horrible, mad, and wrong. It creates variables when you make typos. I keep hoping that they'll remove it from the language.

It sounds like you may be wanting to access the viewport of the device. You can do this by inserting this meta tag in your header.

<meta name="viewport" content="width=device-width, initial-scale=1.0">

http://www.w3schools.com/css/css_rwd_viewport.asp

    ClassLoader cl = ClassLoader.getSystemClassLoader();

    URL[] urls = ((URLClassLoader)cl).getURLs();

    for(URL url: urls){
        System.out.println(url.getFile());
    }

Should be .\SQLExpress or localhost\SQLExpress no $ sign at the end

If you want to uninstall a number of modules, then just run the npm uninstall.

Then go to file package.json and delete the unwanted module from there, and then just run the command npm install. It should fix your problem.

I think above examples are correct. but you dont' really need to set

request.setAttribute("selectedDept", selectedDept);

you can reuse that info from JSTL, just do something like this..

<!DOCTYPE html>

                </c:forEach>

In order to use a CLR 2.0 mixed mode assembly, you need to modify your App.Config file to include:

<?xml version="1.0"?>
<configuration>
  <startup useLegacyV2RuntimeActivationPolicy="true">
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/>
  </startup>
</configuration>

The key is the useLegacyV2RuntimeActivationPolicy flag. This causes the CLR to use the latest version (4.0) to load your mixed mode assembly. Without this, it will not work.

Note that this only matters for mixed mode (C++/CLI) assemblies. You can load all managed CLR 2 assemblies without specifying this in app.config.

Note: When using the System scope (as mentioned on this page), Maven needs absolute paths.

If your jars are under your project's root, you'll want to prefix your systemPath values with ${basedir}.

There is another time when using getBean makes sense. If you're reconfiguring a system that already exists, where the dependencies are not explicitly called out in spring context files. You can start the process by putting in calls to getBean, so that you don't have to wire it all up at once. This way you can slowly build up your spring configuration putting each piece in place over time and getting the bits lined up properly. The calls to getBean will eventually be replaced, but as you understand the structure of the code, or lack there of, you can start the process of wiring more and more beans and using fewer and fewer calls to getBean.

You can create the headers on the fly (no need to specify delimiter when the delimiter is a comma):

Import-CSV $filepath -Header IP1,IP2,IP3,IP4 | Foreach-Object{
   Write-Host $_.IP1
   Write-Host $_.IP2
   ...
}

Try this:

@Request.Url.GetLeftPart(UriPartial.Authority)

you cant ALTER/MODIFY your TYPE. You have to drop the existing and re-create it with correct name/datatype or add a new column/s

You're probably trying to to update the same row of the target table multiple times. I just encountered the very same problem in a merge statement I developed. Make sure your update does not touch the same record more than once in the execution of the merge.

For me for this issue worked to:

• remove ~/.m2
• enable "Full Index Enabled" in maven repository view on central repository
• "Rebuild Index" on central maven repository

After eclipse restart everything worked well.

I had similiar problem. The quick fix I found is to change:

<div class="input-group datepicker" data-provide="datepicker">

to

<div class="input-group date" data-provide="datepicker">

boto3 also has a method for uploading a file directly:

s3 = boto3.resource('s3')    
s3.Bucket('bucketname').upload_file('/local/file/here.txt','folder/sub/path/to/s3key')

http://boto3.readthedocs.io/en/latest/reference/services/s3.html#S3.Bucket.upload_file

I think you want an additional projection that maps each group to a sorted-version of the group:

.Select(group => group.OrderByDescending(student => student.Grade))

It also appears like you might want another flattening operation after that which will give you a sequence of students instead of a sequence of groups:

.SelectMany(group => group)

You can always collapse both into a single SelectMany call that does the projection and flattening together.

EDIT: As Jon Skeet points out, there are certain inefficiencies in the overall query; the information gained from sorting each group is not being used in the ordering of the groups themselves. By moving the sorting of each group to come before the ordering of the groups themselves, the Max query can be dodged into a simpler First query.

I would suggest a very simple way:

import numpy as np
l = [10, 22, 8, 8, 11]
print(np.argmax(l))
print(np.argmin(l))

Hope it helps.

I had similar problem, then I tried writing this from JavaScript and it works! : referenceToYourInputFile.value = "" ;

I just published sheriff, which transforms structs to a map based on tags annotated on the struct fields. You can then marshal (JSON or others) the generated map. It probably doesn't allow you to only serialize the set of fields the caller requested, but I imagine using a set of groups would allow you to cover most cases. Using groups instead of the fields directly would most likely also increase cache-ability.

Example:

package main

import (
    "encoding/json"
    "fmt"
    "log"

    "github.com/hashicorp/go-version"
    "github.com/liip/sheriff"
)

type User struct {
    Username string   `json:"username" groups:"api"`
    Email    string   `json:"email" groups:"personal"`
    Name     string   `json:"name" groups:"api"`
    Roles    []string `json:"roles" groups:"api" since:"2"`
}

func main() {
    user := User{
        Username: "alice",
        Email:    "[email protected]",
        Name:     "Alice",
        Roles:    []string{"user", "admin"},
    }

    v2, err := version.NewVersion("2.0.0")
    if err != nil {
        log.Panic(err)
    }

    o := &sheriff.Options{
        Groups:     []string{"api"},
        ApiVersion: v2,
    }

    data, err := sheriff.Marshal(o, user)
    if err != nil {
        log.Panic(err)
    }

    output, err := json.MarshalIndent(data, "", "  ")
    if err != nil {
        log.Panic(err)
    }
    fmt.Printf("%s", output)
}

css I used to solve this problem, similar to Gjaa but styled better

p
{
    text-align:center;
        }
.styleform label
{
    float:left;
    width: 40%;
    text-align:right;
    }
.styleform input
{
    float:left;
    width: 30%;
    }

Here is my HTML, used specifically for a simple registration form with no php code

<form id="registration">
    <h1>Register</h1>
    <div class="styleform">
    <fieldset id="inputs">
        <p><label>Name:</label> 
          <input id="name" type="text" placeholder="Name" autofocus required>
        </p>
        <p><label>Email:</label>   
          <input id="email" type="text" placeholder="Email Address" required>
        </p>
        <p><label>Username:</label>
          <input id="username" type="text" placeholder="Username" autofocus required>
        </p>
        <p>   
          <label>Password:</label>
          <input id="password" type="password" placeholder="Password" required>
        </p>

    <fieldset id="actions">

    </fieldset>
    </div>
    <p>
          <input type="submit" id="submit" value="Register">
          </p>

It's very simple, and I'm just beginning, but it worked quite nicely

I think that the handling of a dialog should be the responsibility of the view, and the view needs to have code to support that.

If you change the ViewModel - View interaction to handle dialogs then the ViewModel is dependant on that implementation. The simplest way to deal with this problem is to make the View responsible for performing the task. If that means showing a dialog then fine, but could also be a status message in the status bar etc.

My point is that the whole point of the MVVM pattern is to separate business logic from the GUI, so you shouldn't be mixing GUI logic (to display a dialog) in the business layer (the ViewModel).

Here is a simple example of group by in .net core 2.1

var query = this.DbContext.Notifications.
            Where(n=> n.Sent == false).
            GroupBy(n => new { n.AppUserId })
            .Select(g => new { AppUserId = g.Key, Count =  g.Count() });

var query2 = from n in this.DbContext.Notifications
            where n.Sent == false
            group n by n.AppUserId into g
            select new { id = g.Key,  Count = g.Count()};

Which translates to:

SELECT [n].[AppUserId], COUNT(*) AS [Count]
FROM [Notifications] AS [n]
WHERE [n].[Sent] = 0
GROUP BY [n].[AppUserId]

Try

onsubmit="return checkRegistration()"

I also was annoyed by restrictions on what sort of functions pool.map could accept. I wrote the following to circumvent this. It appears to work, even for recursive use of parmap.

from multiprocessing import Process, Pipe
from itertools import izip

def spawn(f):
    def fun(pipe, x):
        pipe.send(f(x))
        pipe.close()
    return fun

def parmap(f, X):
    pipe = [Pipe() for x in X]
    proc = [Process(target=spawn(f), args=(c, x)) for x, (p, c) in izip(X, pipe)]
    [p.start() for p in proc]
    [p.join() for p in proc]
    return [p.recv() for (p, c) in pipe]

if __name__ == '__main__':
    print parmap(lambda x: x**x, range(1, 5))

function in_array(needle, haystack){

    return haystack.indexOf(needle) !== -1;
}

In my case, I was attempting to use TypeBuilder to create a type. TypeBuilder.CreateType threw this exception. I eventually realized that I needed to add MethodAttributes.Virtual to the attributes when calling TypeBuilder.DefineMethod for a method that helps implements an interface. This is because without this flag, the method does not implement the interface, but rather a new method with the same signature instead (even without specifying MethodAttributes.NewSlot).

This was the best solution I found after more time than I care to admit. Basically, add target="_self" to each link that you need to insure a page reload.

http://blog.panjiesw.com/posts/2013/09/angularjs-normal-links-with-html5mode/

I used xsd.exe in the Windows command prompt.

However, since my xml referenced several online xml's (in my case http://www.w3.org/1999/xlink.xsd which references http://www.w3.org/2001/xml.xsd) I had to also download those schematics, put them in the same directory as my xsd, and then list those files in the command:

"C:\Program Files (x86)\Microsoft SDKs\Windows\v8.1A\bin\NETFX 4.5.1 Tools\xsd.exe" /classes /language:CS your.xsd xlink.xsd xml.xsd

You can use this:

String abc = "kushalhs , mayurvm , narendrabz ,";
String a = abc.substring(0, abc.lastIndexOf(","));

This is the working code for your question.

This uses a helper batch file called repl.bat - download from: https://www.dropbox.com/s/qidqwztmetbvklt/repl.bat

Place repl.bat in the same folder as the batch file or in a folder that is on the path.

Repl.bat is a hybrid batch file using native Windows scripting and is far faster than a regular batch script.

The L switch makes the text search and replace a literal string and I'd expect the 12 MB file to complete in several seconds on a modern PC.

@echo off &setlocal
set "search=%~1"
set "replace=%~2"
set "textfile=Input.txt"
set "newfile=Output.txt"
call repl.bat "%search%" "%replace%" L < "%textfile%" >"%newfile%"
del "%textfile%"
rename "%newfile%" "%textfile%"

I'm the author of HPN-SSH and I was asked by a commenter here to weigh in. I'd like to start with a couple of background items. First off, it's important to keep in mind that SSHv2 is a multiplexed protocol - multiple channels over a single TCP connection. As such, the SSH channels are essentially unaware of the underlying flow control algorithm used by TCP. This means that SSHv2 has to implement its own flow control algorithm. The most common implementation basically reimplements sliding windows. The means that you have the SSH sliding window riding on top of the TCP sliding window. The end results is that the effective size of the receive buffer is the minimum of the receive buffers of the two sliding windows. Stock OpenSSH has a maximum receive buffer size of 2MB but this really ends up being closer to ~1.2MB. Most modern OSes have a buffer that can grow (using auto-tuning receive buffers) up to an effective size of 4MB. Why does this matter? If the receive buffer size is less than the bandwidth delay product (BDP) then you will never be able to fully fill the pipe regardless of how fast your system is.

This is complicated by the fact that SFTP adds another layer of flow control onto of the TCP and SSH flow controls. SFTP uses a concept of outstanding messages. Each message may be a command, a result of a command, or bulk data flow. The outstanding messages may be up to a specific datagram size. So you end up with what you might as well think of as yet another receive buffer. The size of this receive buffer is datagram size * maximum outstanding messages (both of which may be set on the command line). The default is 32k * 64 (2MB). So when using SFTP you have to make sure that the TCP receive buffer, the SSH receive buffer, and the SFTP receive buffer are all of sufficient size (without being too large or you can have over buffering problems in interactive sessions).

HPN-SSH directly addresses the SSH buffer problem by having a maximum buffer size of around 16MB. More importantly, the buffer dynamically grows to the proper size by polling the proc entry for the TCP connection's buffer size (basically poking a hole between layers 3 and 4). This avoids overbuffering in almost all situations. In SFTP we raise the maximum number of outstanding requests to 256. At least we should be doing that - it looks like that change didn't propagate as expected to the 6.3 patch set (though it is in 6.2. I'll fix that soon). There isn't a 6.4 version because 6.3 patches cleanly against 6.4 (which is a 1 line security fix from 6.3). You can get the patch set from sourceforge.

I know this sounds odd but right sizing the buffers was the single most important change in terms of performance. In spite of what many people think the encryption is not the real source of poor performance in most cases. You can prove this to yourself by transferring data to sources that are increasingly far away (in terms of RTT). You'll notice that the longer the RTT the lower the throughput. That clearly indicates that this is an RTT dependent performance problem.

Anyway, with this change I started seeing improvements of up to 2 orders of magnitude. If you understand TCP you'll understand why this made such a difference. It's not about the size of the datagram or the number of packets or anything like that. It's entire because in order to make efficient use of the network path you must have a receive buffer equal to the amount of data that can be in transit between the two hosts. This also means that you may not see any improvement whatsoever if the path isn't sufficiently fast and long enough. If the BDP is less than 1.2MB HPN-SSH may be of no value to you.

The parallelized AES-CTR cipher is a performance boost on systems with multiple cores if you need to have full encryption end to end. Usually I suggest people (or have control over both the server and client) to use the NONE cipher switch (encrypted authentication, bulk data passed in clear) as most data isn't all that sensitive. However, this only works in non-interactive sessions like SCP. It doesn't work in SFTP.

There are some other performance improvements as well but nothing as important as the right sizing of the buffers and the encryption work. When I get some free time I'll probably pipeline the HMAC process (currently the biggest drag on performance) and do some more minor optimization work.

So if HPN-SSH is so awesome why hasn't OpenSSH adopted it? That's a long story and people who know the OpenBSD team probably already know the answer. I understand many of their reasons - it's a big patch which would require additional work on their end (and they are a small team), they don't care as much about performance as security (though there is no security implications to HPN-SSH), etc etc etc. However, even though OpenSSH doesn't use HPN-SSH Facebook does. So do Google, Yahoo, Apple, most ever large research data center, NASA, NOAA, the government, the military, and most financial institutions. It's pretty well vetted at this point.

If anyone has any questions feel free to ask but I may not be keeping up to date on this forum. You can always send me mail via the HPN-SSH email address (google it).

For a Maven project using NetBeans 8.x:

1. Click Run >> Set Project Configuration >> Customise
2. Select Actions
3. Select Run file via main()
4. Set name/value pair to include the arguments.
5. Click OK

An example name/value pair might resemble:

javax.persistence.jdbc.password=PASSWORD

Then run your project:

1. Open and focus the Java class that includes main(...).
2. Press F6 to run the program.

The command line parameters should appear in the Run window.

Note that to obtain the value form with the program, use System.getProperty().

Additional actions for Test file, Run project, and other ways to run the application can have arguments defined. Repeat the steps above for the different actions to accomplish this task.

Vohuman's answer lead me to my own implementation:

$(document).on("vclick", ".className", function() {
  // Whatever you want to do
});

Instead of:

$(document).ready(function($) {
  $('.className').click(function(){
    // Whatever you want to do
  });
});

I hope this helps!

You can simply compare 2 strings

function isLater(dateString1, dateString2) {
  return dateString1 > dateString2
}

Then

isLater("2012-12-01", "2012-11-01")

returns true while

isLater("2012-12-01", "2013-11-01")

returns false

Your method must read byte by byte and fully understand and appreciate the byte wise construction of characters. The simplest method is to use an editor which will read anything but only output UTF-8 characters. Textpad is one choice.

• Get the public key from the client phone (adb host)

  cat /data/.android/adbkey.pub

• copy the above public key to the target phone's /data/misc/adb/adb_keys location. (you may need to stop the adb daemon first with stop adbd)

  cat /data/misc/adb/adb_keys

verify both cat outputs match.

try restarting adb daemon on target start adbd or just reboot them.

If you are having problems reading or writing to ADB KEYS in above steps, try setting environment variable ADB_KEYS_PATH with a temporary path (eg: /data/local/tmp). Refer to that link it goes into more details

    "On the host, the user public/private key pair is automatically generated,
    if it does not exist, when the adb daemon starts and is stored in
    $HOME/.android/adb_key(.pub) or in $ANDROID_SDK_HOME on windows. If needed,
    the ADB_KEYS_PATH env variable may be set to a :-separated (; under
    Windows) list of private keys, e.g. company-wide or vendor keys.

    On the device, vendors public keys are installed at build time in
    /adb_keys. User-installed keys are stored in /data/misc/adb/adb_keys"

fit = stats.norm.pdf(h, np.mean(h), np.std(h))  #this is a fitting indeed

pl.plot(h,fit,'-o')

A late answer but I hope it will help anyone visiting here later too..

I will provide categories to save and their respective best methods...

1. Shared Preferences Use this when storing simple values on storage e.g Color theme, app language, last scroll position(in reading apps).. these are simple settings that you would want to persist when the app restarts.. You could, however, use this to store large things(Lists, Maps, Images) but that would require serialization and deserialization.. To learn more on this deserialization and serialization go here.
2. Files This helps a lot when you have data that is defined more by you for example log files, image files and maybe you want to export csv files.. I heard that this type of persistence can be washed by storage cleaners once disk runs out of space.. Am not sure as i have never seen it.. This also can store almost anything but with the help of serialization and deserialization..
3. Saving to a database This is enormously helpful in data which is a bit complex. And I think this doesn't get washed up by disc cleaners as it is stored in AppData(for android).. In this, your data is stored in an SQLite database. Its plugin is SQFLite. Kinds of data that you might wanna put in here are like everything that can be represented by a database.

Replace Operator:=xlOr with Operator:=xlAnd between your criteria. See below the amended script

myRange.AutoFilter Field:=1, Criteria1:="<>A", Operator:=xlAnd, Criteria2:="<>B", Operator:=xlAnd, Criteria3:="<>C"

Because you rebased feature on top of the new master, your local feature is not a fast-forward of origin/feature anymore. So, I think, it's perfectly fine in this case to override the fast-forward check by doing git push origin +feature. You can also specify this in your config

git config remote.origin.push +refs/heads/feature:refs/heads/feature

If other people work on top of origin/feature, they will be disturbed by this forced update. You can avoid that by merging in the new master into feature instead of rebasing. The result will indeed be a fast-forward.

Yes, don't offset vertically or horizontally, and use a relatively large blur radius: fiddle

Also, you can use multiple box-shadows if you separate them with a comma. This will allow you to fine-tune where they blur and how much they extend. The example I provide is indistinguishable from a large outline, but it can be fine-tuned significantly more: fiddle

You missed the last and most relevant property of box-shadow, which is spread-distance. You can specify a value for how much the shadow expands or contracts (makes my second example obsolete): fiddle

The full property list is:

box-shadow: [horizontal-offset] [vertical-offset] [blur-radius] [spread-distance] [color] inset?

But even better, read through the spec.

Or you can use this

Or this

-(void) didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation

If you are on a remote machine, you may also want to add the -f option to force the reboot. Otherwise your session may close and a stubborn app can hang the system.

I use this whenever I want to force an immediate reboot:

shutdown -t 0 -r -f

For a more friendly "give them some time" option, you can use this:

shutdown -t 30 -r

As you can see in the comments, the -f is implied by the timeout.

Brutus 2006 is a utility that provides a GUI for these options.

My favorite smtp server is hMailServer.

It has a nice windows friendly installer and wizard. Hands down the easiest mail server I've ever setup.

It can proxy through your gmail/yahoo/etc account or send email directly.

Once it is installed, email in xampp just works with no config changes.

Make sure you have the application pool set to the correct version of the framework. You'll also need to make sure your aspnet, IIS_IUSRS, or IUSR users have read access to the application's directory.

It should be as simple as using a list of receiving variables:

scanf("%i %i %i", &var1, &var2, &var3);

This could be done via CSS:

<style type="text/css">
@font-face {
    font-family: "My Custom Font";
    src: url(http://www.example.org/mycustomfont.ttf) format("truetype");
}
p.customfont { 
    font-family: "My Custom Font", Verdana, Tahoma;
}
</style>
<p class="customfont">Hello world!</p>

It is supported for all of the regular browsers if you use TrueType-Fonts (TTF), the Web Open Font Format (WOFF) or Embedded Opentype (EOT).

You could use tabs instead of spaces between columns, and/or set maximum size for a column in format strings ...

For those wanting a more secure way to create a random byte array, yes the most secure way is:

byte[] bytes = new byte[20];
SecureRandom.getInstanceStrong().nextBytes(bytes);

BUT your threads might block if there is not enough randomness available on the machine, depending on your OS. The following solution will not block:

SecureRandom random = new SecureRandom();
byte[] bytes = new byte[20];
random.nextBytes(bytes);

This is because the first example uses /dev/random and will block while waiting for more randomness (generated by a mouse/keyboard and other sources). The second example uses /dev/urandom which will not block.

Looks like it is a known problem with EdmGen: http://social.msdn.microsoft.com/forums/en-US/adodotnetentityframework/thread/12aaac4d-2be8-44f3-9448-d7c659585945/

Following the accepted answer, if you do not wish to customize the markup, for separation of concerns or simply because you use a CMS, the following solution works fine:

.valign {_x000D_
  font-size: 0;_x000D_
}_x000D_
_x000D_
.valign > [class*="col"] {_x000D_
  display: inline-block;_x000D_
  float: none;_x000D_
  font-size: 14px;_x000D_
  font-size: 1rem;_x000D_
  vertical-align: middle;_x000D_
}

<link href="//maxcdn.bootstrapcdn.com/bootstrap/3.3.2/css/bootstrap.min.css" rel="stylesheet"/>_x000D_
<div class="row valign">_x000D_
   <div class="col-xs-5">_x000D_
      <div style="height:5em;border:1px solid #000">Big</div>_x000D_
   </div>_x000D_
   <div class="col-xs-5">_x000D_
       <div style="height:3em;border:1px solid #F00">Small</div>_x000D_
   </div>_x000D_
 </div>

The limitation here is that you cannot inherit font size from the parent element because the row sets the font size to 0 in order to remove white space.

I found some useful information in a forum page, quoted below.
From this, mainly the sentences in bold formatting, my answer is:

• Make a bash (shell) script version of your .bat file (like other
  answers, with \ changed to / in file paths). For example:

  # File "example.command":
  #!/bin/bash
  java -cp  ".;./supportlibraries/Framework_Core.jar; ...etc.
  

• Then rename it to have the Mac OS file extension .command.
  That should make the script run using the Terminal app.

• If the app user is going to use a bash script version of the file on Linux
  or run it from the command line, they need to add executable rights
  (change mode bits) using this command, in the folder that has the file:

  chmod +rx [filename].sh
  #or:# chmod +rx [filename].command
  

The forum page question:

Good day, [...] I wondering if there are some "simple" rules to write an equivalent
of the Windows (DOS) bat file. I would like just to click on a file and let it run.

Info from some answers after the question:

Write a shell script, and give it the extension ".command". For example:

#!/bin/bash 
printf "Hello World\n" 

- Mar 23, 2010, Tony T1.

The DOS .BAT file was an attempt to bring to MS-DOS something like the idea of the UNIX script.
In general, UNIX permits you to make a text file with commands in it and run it by simply flagging
the text file as executable (rather than give it a specific suffix). This is how OS X does it.

However, OS X adds the feature that if you give the file the suffix .command, Finder
will run Terminal.app to execute it (similar to how BAT files work in Windows).

Unlike MS-DOS, however, UNIX (and OS X) permits you to specify what interpreter is used
for the script. An interpreter is a program that reads in text from a file and does something
with it. [...] In UNIX, you can specify which interpreter to use by making the first line in the
text file one that begins with "#!" followed by the path to the interpreter. For example [...]

#!/bin/sh
echo Hello World

- Mar 23, 2010, J D McIninch.

Also, info from an accepted answer for Equivalent of double-clickable .sh and .bat on Mac?:

On mac, there is a specific extension for executing shell
scripts by double clicking them: this is .command.

checking with isinstance() would not be enough if you want to know in run time. use:

if(someObject.getClass().equals(C.class){
    // do something
}

You can try this:-

string values = "";
foreach(ListItem item in myCBL.Items){
if(item.Selected)
{
values += item.Value.ToString() + ",";  
}
}
values = values.TrimEnd(',');  //To eliminate comma in last.

My version of hex2rbg:

1. Accept short hex like #fff
2. Algorithm compacity is o(n), should faster than using regex. e.g String.replace, String.split, String.match etc..
3. Use constant space.
4. Support rgb and rgba.

you may need remove hex.trim() if you are using IE8.

e.g.

hex2rgb('#fff') //rgb(255,255,255) 
hex2rgb('#fff', 1) //rgba(255,255,255,1) 
hex2rgb('#ffffff') //rgb(255,255,255)  
hex2rgb('#ffffff', 1) //rgba(255,255,255,1)

code:

function hex2rgb (hex, opacity) {
    hex = hex.trim();
    hex = hex[0] === '#' ? hex.substr(1) : hex;
    var bigint = parseInt(hex, 16), h = [];
    if (hex.length === 3) {
        h.push((bigint >> 4) & 255);
        h.push((bigint >> 2) & 255);
    } else {
        h.push((bigint >> 16) & 255);
        h.push((bigint >> 8) & 255);
    }
    h.push(bigint & 255);
    if (arguments.length === 2) {
        h.push(opacity);
        return 'rgba('+h.join()+')';
    } else {
        return 'rgb('+h.join()+')';
    }
}

If your str() or list() objects might end up being empty as so: astr = '' or alist = [], then you might want to use alist[-1:] instead of alist[-1] for object "sameness".

The significance of this is:

alist = []
alist[-1]   # will generate an IndexError exception whereas 
alist[-1:]  # will return an empty list
astr = ''
astr[-1]    # will generate an IndexError exception whereas
astr[-1:]   # will return an empty str

Where the distinction being made is that returning an empty list object or empty str object is more "last element"-like then an exception object.

I was struggling to get this right using the scripts provided above and some other scripts especially when files and folder names had newline or spaces.

Finally stumbled on tmpreaper and it has been worked pretty well for us so far.

tmpreaper -t 5d ~/Downloads


tmpreaper  --protect '*.c' -t 5h ~/my_prg

Has features like test, which checks the directories recursively and lists them. Ability to delete symlinks, files or directories and also the protection mode for a certain pattern while deleting

I can replace all query parameters with this single line: $location.search({});
Easy to understand and easy way to clear them out.

Updated Answer:

It's been commented multiple times that this is not the correct answer to this question, and I agree. Back when this answer was written, IE 9 was still new (about 8 months old) and many developers including myself needed a solution for <= IE 9. IE 9 is when IE started supporting background-origin. However, it's been over six and a half years, so here's the updated solution which I highly recommend over using an actual border. In case < IE 9 support is needed. My original answer can be found below the demo snippet. It uses an opaque border to simulate padding for background images.

#hello {
  padding-right: 10px;
  background-color:green;
  background: url("https://placehold.it/15/5C5/FFF") no-repeat scroll right center #e8e8e8;
  background-origin: content-box;
}

<p id="hello">I want the background icon to have padding to it too!I want the background icon twant the background icon to have padding to it too!I want the background icon to have padding to it too!I want the background icon to have padding to it too!</p>

Original Answer:

you can fake it with a 10px border of the same color as the background:

http://jsbin.com/eparad/edit#javascript,html,live

#hello {
   border: 10px solid #e8e8e8;
   background-color: green;
   background: url("http://www.costascuisine.com/images/buttons/collapseIcon.gif")
               no-repeat scroll right center #e8e8e8;
}

I know its late to post, but I use the site for my own reference and so I wanted to put an answer here for myself to reference in the future too. I hope you (and others) find it helpful.

Lets pretend a bunch of super Einstein experts designed our database. Our super perfect database has 3 tables, and the following relationships defined between them:

TblA 1:M TblB
TblB 1:M TblC

Notice there is no relationship between TblA and TblC

In most scenarios such a simple database is easy to navigate but in commercial databases it is usually impossible to be able to tell at the design stage all the possible uses and combination of uses for data, tables, and even whole databases, especially as systems get built upon and other systems get integrated or switched around or out. This simple fact has spawned a whole industry built on top of databases called Business Intelligence. But I digress...

In the above case, the structure is so simple to understand that its easy to see you can join from TblA, through to B, and through to C and vice versa to get at what you need. It also very vaguely highlights some of the problems with doing it. Now expand this simple chain to 10 or 20 or 50 relationships long. Now all of a sudden you start to envision a need for exactly your scenario. In simple terms, a join from A to C or vice versa or A to F or B to Z or whatever as our system grows.

There are many ways this can indeed be done. The one mentioned above being the most popular, that is driving through all the links. The major problem is that its very slow. And gets progressively slower the more tables you add to the chain, the more those tables grow, and the further you want to go through it.

Solution 1: Look for a common link. It must be there if you taught of a reason to join A to C. If it is not obvious, create a relationship and then join on it. i.e. To join A through B through C there must be some commonality or your join would either produce zero results or a massive number or results (Cartesian product). If you know this commonality, simply add the needed columns to A and C and link them directly.

The rule for relationships is that they simply must have a reason to exist. Nothing more. If you can find a good reason to link from A to C then do it. But you must ensure your reason is not redundant (i.e. its already handled in some other way).

Now a word of warning. There are some pitfalls. But I don't do a good job of explaining them so I will refer you to my source instead of talking about it here. But remember, this is getting into some heavy stuff, so this video about fan and chasm traps is really only a starting point. You can join without relationships. But I advise watching this video first as this goes beyond what most people learn in college and well into the territory of the BI and SAP guys. These guys, while they can program, their day job is to specialise in exactly this kind of thing. How to get massive amounts of data to talk to each other and make sense.

This video is one of the better videos I have come across on the subject. And it's worth looking over some of his other videos. I learned a lot from him.

In my case the problem was related to "Referencing .NET standard library in classic asp.net projects" and these two issues

https://github.com/dotnet/standard/issues/873

https://github.com/App-vNext/Polly/issues/628

and downgrading to Polly v6 was enough to workaround it

Note that your pod specs will remain, and are located at ~/.cocoapods/ . This directory may also need to be removed if you want a completely fresh install.

They can be removed using pod spec remove SPEC_NAME then pod setup

It may help to do pod spec remove master then pod setup

If you have something else altering the DB (say another process) and need to ensure you see these changes, use AsNoTracking(), otherwise EF may give you the last copy that your context had instead, hence it being good to usually use a new context every query:

If the value of a disabled textbox needs to be retained when a form is cleared (reset), disabled = "disabled" has to be used, as read-only textbox will not retain the value

For Example:

HTML

Textbox

<input type="text" id="disabledText" name="randombox" value="demo" disabled="disabled" />

Reset button

<button type="reset" id="clearButton">Clear</button>

In the above example, when Clear button is pressed, disabled text value will be retained in the form. Value will not be retained in the case of input type = "text" readonly="readonly"

build gradle:

testImplementation "com.nhaarman.mockitokotlin2:mockito-kotlin:2.2.0"

code:

interface MyCallback {
  fun someMethod(value: String)
}

class MyTestableManager(private val callback: MyCallback){
  fun perform(){
    callback.someMethod("first")
    callback.someMethod("second")
    callback.someMethod("third")
  }
}

test:

import com.nhaarman.mockitokotlin2.times
import com.nhaarman.mockitokotlin2.verify
import com.nhaarman.mockitokotlin2.mock
...
val callback: MyCallback = mock()
val manager = MyTestableManager(callback)
manager.perform()

val captor: KArgumentCaptor<String> = com.nhaarman.mockitokotlin2.argumentCaptor<String>()

verify(callback, times(3)).someMethod(captor.capture())

assertTrue(captor.allValues[0] == "first")
assertTrue(captor.allValues[1] == "second")
assertTrue(captor.allValues[2] == "third")

You can use composition instead... this will allow you to access class objects from the static type. But still cant implements interfaces or abstract classes

Better to use the following; Works always!

var ext =  fileName.split('.').pop();

This will return the extension without a dot prefix. You can add "." + ext to check against the extensions you wish to support!

You should

$ brew install bash bash-completion git

Then source "$(brew --prefix)/etc/bash_completion" in your .bashrc.

TL;DR: The biggest difference in everyday use isn't nested dependencies... it's the difference between modules and globals.

I think the previous posters have covered well some of the basic distinctions. (npm's use of nested dependencies is indeed very helpful in managing large, complex applications, though I don't think it's the most important distinction.)

I'm surprised, however, that nobody has explicitly explained one of the most fundamental distinctions between Bower and npm. If you read the answers above, you'll see the word 'modules' used often in the context of npm. But it's mentioned casually, as if it might even just be a syntax difference.

But this distinction of modules vs. globals (or modules vs. 'scripts') is possibly the most important difference between Bower and npm. The npm approach of putting everything in modules requires you to change the way you write Javascript for the browser, almost certainly for the better.

The Bower Approach: Global Resources, Like <script> Tags

At root, Bower is about loading plain-old script files. Whatever those script files contain, Bower will load them. Which basically means that Bower is just like including all your scripts in plain-old <script>'s in the <head> of your HTML.

So, same basic approach you're used to, but you get some nice automation conveniences:

• You used to need to include JS dependencies in your project repo (while developing), or get them via CDN. Now, you can skip that extra download weight in the repo, and somebody can do a quick bower install and instantly have what they need, locally.
• If a Bower dependency then specifies its own dependencies in its bower.json, those'll be downloaded for you as well.

But beyond that, Bower doesn't change how we write javascript. Nothing about what goes inside the files loaded by Bower needs to change at all. In particular, this means that the resources provided in scripts loaded by Bower will (usually, but not always) still be defined as global variables, available from anywhere in the browser execution context.

The npm Approach: Common JS Modules, Explicit Dependency Injection

All code in Node land (and thus all code loaded via npm) is structured as modules (specifically, as an implementation of the CommonJS module format, or now, as an ES6 module). So, if you use NPM to handle browser-side dependencies (via Browserify or something else that does the same job), you'll structure your code the same way Node does.

Smarter people than I have tackled the question of 'Why modules?', but here's a capsule summary:

• Anything inside a module is effectively namespaced, meaning it's not a global variable any more, and you can't accidentally reference it without intending to.
• Anything inside a module must be intentionally injected into a particular context (usually another module) in order to make use of it
• This means you can have multiple versions of the same external dependency (lodash, let's say) in various parts of your application, and they won't collide/conflict. (This happens surprisingly often, because your own code wants to use one version of a dependency, but one of your external dependencies specifies another that conflicts. Or you've got two external dependencies that each want a different version.)
• Because all dependencies are manually injected into a particular module, it's very easy to reason about them. You know for a fact: "The only code I need to consider when working on this is what I have intentionally chosen to inject here".
• Because even the content of injected modules is encapsulated behind the variable you assign it to, and all code executes inside a limited scope, surprises and collisions become very improbable. It's much, much less likely that something from one of your dependencies will accidentally redefine a global variable without you realizing it, or that you will do so. (It can happen, but you usually have to go out of your way to do it, with something like window.variable. The one accident that still tends to occur is assigning this.variable, not realizing that this is actually window in the current context.)
• When you want to test an individual module, you're able to very easily know: exactly what else (dependencies) is affecting the code that runs inside the module? And, because you're explicitly injecting everything, you can easily mock those dependencies.

To me, the use of modules for front-end code boils down to: working in a much narrower context that's easier to reason about and test, and having greater certainty about what's going on.

It only takes about 30 seconds to learn how to use the CommonJS/Node module syntax. Inside a given JS file, which is going to be a module, you first declare any outside dependencies you want to use, like this:

var React = require('react');

Inside the file/module, you do whatever you normally would, and create some object or function that you'll want to expose to outside users, calling it perhaps myModule.

At the end of a file, you export whatever you want to share with the world, like this:

module.exports = myModule;

Then, to use a CommonJS-based workflow in the browser, you'll use tools like Browserify to grab all those individual module files, encapsulate their contents at runtime, and inject them into each other as needed.

AND, since ES6 modules (which you'll likely transpile to ES5 with Babel or similar) are gaining wide acceptance, and work both in the browser or in Node 4.0, we should mention a good overview of those as well.

More about patterns for working with modules in this deck.

EDIT (Feb 2017): Facebook's Yarn is a very important potential replacement/supplement for npm these days: fast, deterministic, offline package-management that builds on what npm gives you. It's worth a look for any JS project, particularly since it's so easy to swap it in/out.

EDIT (May 2019) "Bower has finally been deprecated. End of story." (h/t: @DanDascalescu, below, for pithy summary.)

And, while Yarn is still active, a lot of the momentum for it shifted back to npm once it adopted some of Yarn's key features.

You might have to move the mouse to any particular location after context click() like this -

Actions action = new Actions(driver);
actions.contextClick(link).moveByOffset(x,y).click().build().perform();

To understand how moveByOffset(x,y) works look here;

I hope this works. You will have to calculate the offset values for x and y;

best way would be to find the size of each option button after right clicking and then if you click on the 2nd option .

x = width of option button/2

y = 2*(size of each option button)

You actually got it. Just forgot some quotes.

$(this).css({backgroundColor: 'red'});

or

$(this).css('background-color', 'red');

You don't need to pass over a map/object to set only one property. You can just put pass it as string. Note that if passing an object you cannot use a -. All CSS properties which have such a character are mapped with capital letters.

Reference: .css()

Here's another example using the Tuple class with the Dictionary.

        // Setup Dictionary
    Dictionary<Tuple<string, string>, string> testDictionary = new Dictionary<Tuple<string, string>, string>
    {
        {new Tuple<string, string>("key1","key2"), "value1"},
        {new Tuple<string, string>("key1","key3"), "value2"},
        {new Tuple<string, string>("key2","key3"), "value3"}
    };
    //Query Dictionary
    public string FindValue(string stuff1, string stuff2)
    {
        return testDictionary[Tuple.Create(stuff1, stuff2)];
    }

This will do what you want (list of towns, with the number of users in each):

select town, count(town) 
from user
group by town

You can use most aggregate functions when using GROUP BY.

Update (following change to question and comments)

You can declare a variable for the number of users and set it to the number of users then select with that.

DECLARE @numOfUsers INT
SET @numOfUsers = SELECT COUNT(*) FROM user

SELECT DISTINCT town, @numOfUsers
FROM user

According to the pytest docs, pytest --capture=sys should work. If you want to capture standard out inside a test, refer to the capsys fixture.

For listing your tables use:

SELECT table_name FROM information_schema.tables WHERE table_schema='public'

It will only list tables that you create.

I've tested this for my project, it finds the max/min in O(n) time:

from django.db.models import Max

# Find the maximum value of the rating and then get the record with that rating. 
# Notice the double underscores in rating__max
max_rating = App.objects.aggregate(Max('rating'))['rating__max']
return App.objects.get(rating=max_rating)

This is guaranteed to get you one of the maximum elements efficiently, rather than sorting the whole table and getting the top (around O(n*logn)).

You can use the sequence method list.extend to extend the list by multiple values from any kind of iterable, being it another list or any other thing that provides a sequence of values.

>>> lst = [1, 2]
>>> lst.append(3)
>>> lst.append(4)
>>> lst
[1, 2, 3, 4]

>>> lst.extend([5, 6, 7])
>>> lst.extend((8, 9, 10))
>>> lst
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

>>> lst.extend(range(11, 14))
>>> lst
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13]

So you can use list.append() to append a single value, and list.extend() to append multiple values.

           <script>

Just sort by whatever (mpg for example, question is not clear on this)

mt <- mtcars[order(mtcars$mpg), ]

then use the by function to get the top n rows in each group

d <- by(mt, mt["cyl"], head, n=4)

If you want the result to be a data.frame:

Reduce(rbind, d)

Edit: Handling ties is more difficult, but if all ties are desired:

by(mt, mt["cyl"], function(x) x[rank(x$mpg) %in% sort(unique(rank(x$mpg)))[1:4], ])

Another approach is to break ties based on some other information, e.g.,

mt <- mtcars[order(mtcars$mpg, mtcars$hp), ]
by(mt, mt["cyl"], head, n=4)

Maybe you can use:

xxx:
    for i in `seq 1 4`; do ./a.out $$i; done;

The two main differences are:

• when you capture even a single argument, you are able to make much more elaborate tests on this argument, and with more obvious code;
• an ArgumentCaptor can capture more than once.

To illustrate the latter, say you have:

final ArgumentCaptor<Foo> captor = ArgumentCaptor.forClass(Foo.class);

verify(x, times(4)).someMethod(captor.capture()); // for instance

Then the captor will be able to give you access to all 4 arguments, which you can then perform assertions on separately.

This or any number of arguments in fact, since a VerificationMode is not limited to a fixed number of invocations; in any event, the captor will give you access to all of them, if you wish.

This also has the benefit that such tests are (imho) much easier to write than having to implement your own ArgumentMatchers -- particularly if you combine mockito with assertj.

Oh, and please consider using TestNG instead of JUnit.

I have been considering using Lazy<T> properties to help improve the performance of my own code (and to learn a bit more about it). I came here looking for answers about when to use it but it seems that everywhere I go there are phrases like:

Use lazy initialization to defer the creation of a large or resource-intensive object, or the execution of a resource-intensive task, particularly when such creation or execution might not occur during the lifetime of the program.

from MSDN Lazy<T> Class

I am left a bit confused because I am not sure where to draw the line. For example, I consider linear interpolation as a fairly quick computation but if I don't need to do it then can lazy initialisation help me to avoid doing it and is it worth it?

In the end I decided to try my own test and I thought I would share the results here. Unfortunately I am not really an expert at doing these sort of tests and so I am happy to get comments that suggest improvements.

Description

For my case, I was particularly interested to see if Lazy Properties could help improve a part of my code that does a lot of interpolation (most of it being unused) and so I have created a test that compared 3 approaches.

I created a separate test class with 20 test properties (lets call them t-properties) for each approach.

• GetInterp Class: Runs linear interpolation every time a t-property is got.
• InitInterp Class: Initialises the t-properties by running the linear interpolation for each one in the constructor. The get just returns a double.
• InitLazy Class: Sets up the t-properties as Lazy properties so that linear interpolation is run once when the property is first got. Subsequent gets should just return an already calculated double.

The test results are measured in ms and are the average of 50 instantiations or 20 property gets. Each test was then run 5 times.

Test 1 Results: Instantiation (average of 50 instantiations)

Observations

GetInterp is fastest to instantiate as expected because its not doing anything. InitLazy is faster to instantiate than InitInterp suggesting that the overhead in setting up lazy properties is faster than my linear interpolation calculation. However, I am a bit confused here because InitInterp should be doing 20 linear interpolations (to set up it's t-properties) but it is only taking 0.09 ms to instantiate (test 1), compared to GetInterp which takes 0.28 ms to do just one linear interpolation the first time (test 2), and 0.1 ms to do it the second time (test 3).

It takes InitLazy almost 2 times longer than GetInterp to get a property the first time, while InitInterp is the fastest, because it populated its properties during instantiation. (At least that is what it should have done but why was it's instantiation result so much quicker than a single linear interpolation? When exactly is it doing these interpolations?)

Unfortunately it looks like there is some automatic code optimisation going on in my tests. It should take GetInterp the same time to get a property the first time as it does the second time, but it is showing as more than 2x faster. It looks like this optimisation is also affecting the other classes as well since they are all taking about the same amount of time for test 3. However, such optimisations may also take place in my own production code which may also be an important consideration.

Conclusions

While some results are as expected, there are also some very interesting unexpected results probably due to code optimisations. Even for classes that look like they are doing a lot of work in the constructor, the instantiation results show that they may still be very quick to create, compared to getting a double property. While experts in this field may be able to comment and investigate more thoroughly, my personal feeling is that I need to do this test again but on my production code in order to examine what sort of optimisations may be taking place there too. However, I am expecting that InitInterp may be the way to go.

You need to checkout the repository onto your local machine. Then you can change that folder on your local machine.

git commit -am "added files"

That command will commit all files to the repo.

git push origin master

that will push all changes in your master branch (which I assume is the one you're using) to the remote repository origin (in this case github)

You don't want to do that. It can cause undefined behavior depending on the collection. You want to use an Iterator directly. Although the for each construct is syntactic sugar and is really using an iterator, it hides it from your code so you can't access it to call Iterator.remove.

The behavior of an iterator is unspecified if the underlying collection is modified while the iteration is in progress in any way other than by calling this method.

Instead write your code:

List<String> names = ....
Iterator<String> it = names.iterator();
while (it.hasNext()) {

    String name = it.next();
    // Do something
    it.remove();
}

Note that the code calls Iterator.remove, not List.remove.

Addendum:

Even if you are removing an element that has not been iterated over yet, you still don't want to modify the collection and then use the Iterator. It might modify the collection in a way that is surprising and affects future operations on the Iterator.

convert to Array

var array = like.ToArray();
var first = array[0];

I don't think there's a jQuery-way to directly access the pseudoclass' rules, but you could always append a new style element to the document's head like:

$('head').append('<style>.column:before{width:800px !important;}</style>');

See a live demo here

I also remember having seen a plugin that tackles this issue once but I couldn't find it on first googling unfortunately.

The suggestions from stb and xiowl are fine if you're looking for a constant. If you need to use existing fields or parameters which are integers, you can cast them to be floats first:

SELECT CAST(1 AS float) / CAST(3 AS float)

or

SELECT CAST(MyIntField1 AS float) / CAST(MyIntField2 AS float)

You need to link with the math library:

gcc -o sphere sphere.c -lm

The error you are seeing: error: ld returned 1 exit status is from the linker ld (part of gcc that combines the object files) because it is unable to find where the function pow is defined.

Including math.h brings in the declaration of the various functions and not their definition. The def is present in the math library libm.a. You need to link your program with this library so that the calls to functions like pow() are resolved.

Stopping Event Propagation in some particular elements ma y become dangerous as it may prevent other some scripts from running. So check whether the triggering is from the excluded area from inside the function.

$(document).on('click', function(event) {
  if (!$(event.target).closest('#menucontainer').length) {
    // Hide the menus.
  }
});

Here function is initiated when clicking on document, but it excludes triggering from #menucontainer. For details https://css-tricks.com/dangers-stopping-event-propagation/

Access the element you want to change via the DOM, for example with document.getElementById() or via this in your event handler, and change the style in that element:

document.getElementById("MyHeader").style.backgroundColor='red';

EDIT

You can use getElementsByTagName too, (untested) example:

function colorElementAndH2(elem, colorElem, colorH2) {
    // change element background color
    elem.style.backgroundColor = colorElem;
    // color first contained h2
    var h2s = elem.getElementsByTagName("h2");
    if (h2s.length > 0)
    {
        hs2[0].style.backgroundColor = colorH2;
    }
}

// add event handlers when complete document has been loaded
window.onload = function() {
    // add to _all_ divs (not sure if this is what you want though)

This code:

from scipy.stats import linregress

linregress(x,y) #x and y are arrays or lists.

gives out a list with the following:

slope : float
slope of the regression line
intercept : float
intercept of the regression line
r-value : float
correlation coefficient
p-value : float
two-sided p-value for a hypothesis test whose null hypothesis is that the slope is zero
stderr : float
Standard error of the estimate

This is one of the poor supported features in SQL Reporting Services.

What you need to do is pass all of your selected items as a single string to your stored procedure. Each element within the string will be separated by a comma.

What I then do is split the string using a function that returns the provided string as a table. See below.

ALTER FUNCTION [dbo].[fn_MVParam]
   (@RepParam nvarchar(4000), @Delim char(1)= ',')
RETURNS @Values TABLE (Param nvarchar(4000))AS
  BEGIN
  DECLARE @chrind INT
  DECLARE @Piece nvarchar(100)
  SELECT @chrind = 1 
  WHILE @chrind > 0
    BEGIN
      SELECT @chrind = CHARINDEX(@Delim,@RepParam)
      IF @chrind  > 0
        SELECT @Piece = LEFT(@RepParam,@chrind - 1)
      ELSE
        SELECT @Piece = @RepParam
      INSERT  @Values(Param) VALUES(CAST(@Piece AS VARCHAR))
      SELECT @RepParam = RIGHT(@RepParam,LEN(@RepParam) - @chrind)
      IF LEN(@RepParam) = 0 BREAK
    END
  RETURN
  END

You can then reference the results in the where clause of your main query like so:

where someColumn IN(SELECT Param FROM dbo.fn_MVParam(@sParameterString,','))

I hope this you find this solution to be of use. Please feel free to pose any questions you may have.

Cheers,John

if you directly get get max number by writing select query then there may chance that your query will give wrong value. e.g. if your table has 5 records so your increment id will be 6 and if I delete record no 5 the your table has 4 records with max id is 4 in this case you will get 5 as next increment id. insted to that you can get info from mysql defination itself. by writing following code in php

<?
$tablename      = "tablename";
$next_increment     = 0;
$qShowStatus        = "SHOW TABLE STATUS LIKE '$tablename'";
$qShowStatusResult  = mysql_query($qShowStatus) or die ( "Query failed: " . mysql_error() . "<br/>" . $qShowStatus );

$row = mysql_fetch_assoc($qShowStatusResult);
$next_increment = $row['Auto_increment'];

echo "next increment number: [$next_increment]";
?>

Unless there is an overwhelming need to create a mess of variable names, I would just use a dictionary, where you can dynamically create the key names and associate a value to each.

a = {}
k = 0
while k < 10:
    <dynamically create key> 
    key = ...
    <calculate value> 
    value = ...
    a[key] = value 
    k += 1

There are also some interesting data structures in the new 'collections' module that might be applicable:

http://docs.python.org/dev/library/collections.html

You could use a pseudo element for this, and have your image on a hover:

.image {_x000D_
  position: relative;_x000D_
  height: 300px;_x000D_
  width: 300px;_x000D_
  background: url(http://lorempixel.com/300/300);_x000D_
}_x000D_
.image:before {_x000D_
  content: "";_x000D_
  position: absolute;_x000D_
  top: 0;_x000D_
  left: 0;_x000D_
  height: 100%;_x000D_
  width: 100%;_x000D_
  transition: all 0.8s;_x000D_
  opacity: 0;_x000D_
  background: url(http://lorempixel.com/300/200);_x000D_
  background-size: 100% 100%;_x000D_
}_x000D_
.image:hover:before {_x000D_
  opacity: 0.8;_x000D_
}

<div class="image"></div>

ListView.FocusedItem.Index 

or you can use foreach loop like this

int index= -1;
foreach (ListViewItem itm in listView1.SelectedItems)
{
    if (itm.Selected)
    {
        index= itm.Index;
    }
}

Brute attempt to detect working time - Monday to Friday 8am-4pm:

if (date('N')<6 && date('G')>8 && date('G')<16) {
   // we have a working time (or check for holidays)
}

best and simple way to use native java Script which is one liner code.

document.querySelector('#id').click();

Just add 'id' to your html element like

<button id="myId1" ng-click="someFunction()"></button>

check condition in javascript code

if(condition) { document.querySelector('#myId1').click(); }

Create an empty file called .gitkeep in the directory, and add that.

A regex will probably be quite efficient, because you would specify ranges: [0-9a-zA-Z]. Assuming the implementation code for regexes is efficient, this would simply require an upper and lower bound comparison for each range. Here's basically what a compiled regex should do:

boolean isAlphanumeric(String str) {
    for (int i=0; i<str.length(); i++) {
        char c = str.charAt(i);
        if (c < 0x30 || (c >= 0x3a && c <= 0x40) || (c > 0x5a && c <= 0x60) || c > 0x7a)
            return false;
    }

    return true;
}

I don't see how your code could be more efficient than this, because every character will need to be checked, and the comparisons couldn't really be any simpler.

I suggest to use utf8mb4_unicode_ci, which is based on the Unicode standard for sorting and comparison, which sorts accurately in a very wide range of languages.

Late reply for future reference. What was working for me was enabling it by nuget and then adding custom headers into web.config.

Use application/javascript as content type instead of text/javascript

text/javascript is mentioned obsolete. See reference docs.

http://www.iana.org/assignments/media-types/application

Also see this question on SO.

UPDATE:

I have tried executing the code you have given and the below didn't work.

res.setHeader('content-type', 'text/javascript');
res.send(JS_Script);

This is what worked for me.

res.setHeader('content-type', 'text/javascript');
res.end(JS_Script);

As robertklep has suggested, please refer to the node http docs, there is no response.send() there.

I hate answering my own question, but @Matt Bodily put me on the right track.

The @Html.Action method actually invokes a controller and renders the view, so that wouldn't work to create a snippet of HTML in my case, as this was causing a recursive function call resulting in a StackOverflowException. The @Url.Action(action, controller, { area = "abc" }) does indeed return the URL, but I finally discovered an overload of Html.ActionLink that provided a better solution for my case:

@Html.ActionLink("Admin", "Index", "Home", new { area = "Admin" }, null)

Note: , null is significant in this case, to match the right signature.

Documentation: @Html.ActionLink (LinkExtensions.ActionLink)

Documentation for this particular overload:

LinkExtensions.ActionLink(Controller, Action, Text, RouteArgs, HtmlAttributes)

It's been difficult to find documentation for these helpers. I tend to search for "Html.ActionLink" when I probably should have searched for "LinkExtensions.ActionLink", if that helps anyone in the future.

Still marking Matt's response as the answer.

Edit: Found yet another HTML helper to solve this:

@Html.RouteLink("Admin", new { action = "Index", controller = "Home", area = "Admin" })

You need to use split("");.

That will split it by every character.

However I think it would be better to iterate over a String's characters like so:

for (int i = 0;i < str.length(); i++){
    System.out.println(str.charAt(i));
}

It is unnecessary to create another copy of your String in a different form.

There isn't a single answer to this question as there are too many variables, but SHA2 is not yet really cracked (see: Lifetimes of cryptographic hash functions) so it is still a good algorithm to use to store passwords in. The use of salt is good because it prevents attack from dictionary attacks or rainbow tables. Importance of a salt is that it should be unique for each password. You can use a format like [128-bit salt][512-bit password hash] when storing the hashed passwords.

The only viable way to attack is to actually calculate hashes for different possibilities of password and eventually find the right one by matching the hashes.

To give an idea about how many hashes can be done in a second, I think Bitcoin is a decent example. Bitcoin uses SHA256 and to cut it short, the more hashes you generate, the more bitcoins you get (which you can trade for real money) and as such people are motivated to use GPUs for this purpose. You can see in the hardware overview that an average graphic card that costs only $150 can calculate more than 200 million hashes/s. The longer and more complex your password is, the longer time it will take. Calculating at 200M/s, to try all possibilities for an 8 character alphanumberic (capital, lower, numbers) will take around 300 hours. The real time will most likely less if the password is something eligible or a common english word.

As such with anything security you need to look at in context. What is the attacker's motivation? What is the kind of application? Having a hash with random salt for each gives pretty good protection against cases where something like thousands of passwords are compromised.

One thing you can do is also add additional brute force protection by slowing down the hashing procedure. As you only hash passwords once, and the attacker has to do it many times, this works in your favor. The typical way to do is to take a value, hash it, take the output, hash it again and so forth for a fixed amount of iterations. You can try something like 1,000 or 10,000 iterations for example. This will make it that many times times slower for the attacker to find each password.

Here's a dirty hack -

You have your element here (adding the disabled attribute):

<input type="text" name="test" id="test" disabled="disabled" />

And then at the bottom of your webpage put some JavaScript:

<script>
    setTimeout(function(){
        document.getElementById('test').removeAttribute("disabled");
        },100);
</script>

For the common case where you need to throw an exception in response to some unexpected conditions, and that you never intend to catch, but simply to fail fast to enable you to debug from there if it ever happens — the most logical one seems to be AssertionError:

if 0 < distance <= RADIUS:
    #Do something.
elif RADIUS < distance:
    #Do something.
else:
    raise AssertionError("Unexpected value of 'distance'!", distance)

Use \t to add tab and \n for new line, here is a simple example below.

<string name="list_with_tab_tag">\tbanana\torange\tblueberry\tmango</string>
<string name="sentence_with_new_line_tag">This is the first sentence\nThis is the second scentence\nThis is the third sentence</string>

Though the question appears to be demanding plotting a histogram using matplotlib.hist() function, it can arguably be not done using the same as the latter part of the question demands to use the given probabilities as the y-values of bars and given names(strings) as the x-values.

I'm assuming a sample list of names corresponding to given probabilities to draw the plot. A simple bar plot serves the purpose here for the given problem. The following code can be used:

import matplotlib.pyplot as plt
probability = [0.3602150537634409, 0.42028985507246375, 
  0.373117033603708, 0.36813186813186816, 0.32517482517482516, 
  0.4175257731958763, 0.41025641025641024, 0.39408866995073893, 
  0.4143222506393862, 0.34, 0.391025641025641, 0.3130841121495327, 
  0.35398230088495575]
names = ['name1', 'name2', 'name3', 'name4', 'name5', 'name6', 'name7', 'name8', 'name9',
'name10', 'name11', 'name12', 'name13'] #sample names
plt.bar(names, probability)
plt.xticks(names)
plt.yticks(probability) #This may be included or excluded as per need
plt.xlabel('Names')
plt.ylabel('Probability')

I have built an module for this if you want to add styles based on a condition like this:

multipleStyles(styles.icon, { [styles.iconRed]: true })

https://www.npmjs.com/package/react-native-multiple-styles

Here's generally how to select multiple columns from a subquery:

SELECT
     A.SalesOrderID,
     A.OrderDate,
     SQ.Max_Foo,
     SQ.Max_Foo2
FROM
     A
LEFT OUTER JOIN
     (
     SELECT
          B.SalesOrderID,
          MAX(B.Foo) AS Max_Foo,
          MAX(B.Foo2) AS Max_Foo2
     FROM
          B
     GROUP BY
          B.SalesOrderID
     ) AS SQ ON SQ.SalesOrderID = A.SalesOrderID

If what you're ultimately trying to do is get the values from the row with the highest value for Foo (rather than the max of Foo and the max of Foo2 - which is NOT the same thing) then the following will usually work better than a subquery:

SELECT
     A.SalesOrderID,
     A.OrderDate,
     B1.Foo,
     B1.Foo2
FROM
     A
LEFT OUTER JOIN B AS B1 ON
     B1.SalesOrderID = A.SalesOrderID
LEFT OUTER JOIN B AS B2 ON
     B2.SalesOrderID = A.SalesOrderID AND
     B2.Foo > B1.Foo
WHERE
     B2.SalesOrderID IS NULL

You're basically saying, give me the row from B where I can't find any other row from B with the same SalesOrderID and a greater Foo.

I guess that what you want to do is an UNION of both tables.

If both tables have the same columns then you can just do

SELECT category_id, col1, col2, col3
  FROM items_a
UNION 
SELECT category_id, col1, col2, col3 
  FROM items_b

Else, you might have to do something like

SELECT category_id, col1, col2, col3
  FROM items_a 
UNION 
SELECT category_id, col_1 as col1, col_2 as col2, col_3 as col3
  FROM items_b

Imho, most straightforward and universal code:

dft=data.frame(x = sample(letters[1:8], 20, replace=TRUE))
dft=within(dft,{
    y=NA
    y[x %in% c('a','b','c')]='abc'
    y[x %in% c('d','e','f')]='def'
    y[x %in% 'g']='g'
    y[x %in% 'h']='h'
})

The error is because fName is included in the SELECT list, but is not included in a GROUP BY clause and is not part of an aggregate function (Count(), Min(), Max(), Sum(), etc.)

You can fix that problem by including fName in a GROUP BY. But then you will face the same issue with surname. So put both in the GROUP BY:

SELECT
    fName,
    surname,
    Count(*) AS num_rows
FROM
    author
    INNER JOIN book
    ON author.aID = book.authorID;
GROUP BY
    fName,
    surname

Note I used Count(*) where you wanted SUM(orders.quantity). However, orders isn't included in the FROM section of your query, so you must include it before you can Sum() one of its fields.

If you have Access available, build the query in the query designer. It can help you understand what features are possible and apply the correct Access SQL syntax.

One more important thing needs to be highlighted. It's better to use params because it is better for performance. When you call a method with params argument and passed to it nothing:

public void ExampleMethod(params string[] args)
{
// do some stuff
}

call:

ExampleMethod();

Then a new versions of the .Net Framework do this (from .Net Framework 4.6):

ExampleMethod(Array.Empty<string>());

This Array.Empty object can be reused by framework later, so there are no needs to do redundant allocations. These allocations will occur when you call this method like this:

 ExampleMethod(new string[] {});

hey i got same error and the solution to this error is just write Capital M instead of small m.. eg:- static void Main() I hope it helps..

Main Difference Between PUT and PATCH Requests:

Suppose we have a resource that holds the first name and last name of a person.

If we want to change the first name then we send a put request for Update

{ "first": "Michael", "last": "Angelo" }

Here, although we are only changing the first name, with PUT request we have to send both parameters first and last.
In other words, it is mandatory to send all values again, the full payload.

When we send a PATCH request, however, we only send the data which we want to update. In other words, we only send the first name to update, no need to send the last name.

It is not good practice to hard code strings into your layout files. You should add them to a string resource file and then reference them from your layout.

This allows you to update every occurrence of the word "Yellow" in all layouts at the same time by just editing your strings.xml file.

It is also extremely useful for supporting multiple languages as a separate strings.xml file can be used for each supported language.

example: XML file saved at res/values/strings.xml:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="yellow">Yellow</string>
</resources>

This layout XML applies a string to a View:

<TextView android:layout_width="fill_parent"
          android:layout_height="wrap_content"
          android:text="@string/yellow" />

Similarly colors should be stored in colors.xml and then referenced by using @color/color_name

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="Black">#000000</color>
</resources>

There are two html entity code : ₹ ₹

On *nix, you can use comm. The answer to the question is:

comm -1 -2 file1.sorted file2.sorted 
# where file1 and file2 are sorted and piped into *.sorted

Here's the full usage of comm:

comm [-1] [-2] [-3 ] file1 file2
-1 Suppress the output column of lines unique to file1.
-2 Suppress the output column of lines unique to file2.
-3 Suppress the output column of lines duplicated in file1 and file2. 

Also note that it is important to sort the files before using comm, as mentioned in the man pages.

I just developed a javascript library called JIC to solve that problem. It allows you to compress jpg and png on the client side 100% with javascript and no external libraries required!

UPDATED
Some time on, I see a comment that brings me back to my old answer, and I think I'd do it differently now. These days I'd write:

private static IEnumerable<T> GetEnumValues<T>()
{
    // Can't use type constraints on value types, so have to do check like this
    if (typeof(T).BaseType != typeof(Enum))
    {
        throw new ArgumentException("T must be of type System.Enum");
    }

    return Enum.GetValues(typeof(T)).Cast<T>();
}

The simple approach (gcc -dM -E - < /dev/null) works fine for gcc but fails for g++. Recently I required a test for a C++11/C++14 feature. Recommendations for their corresponding macro names are published at https://isocpp.org/std/standing-documents/sd-6-sg10-feature-test-recommendations. But:

g++ -dM -E - < /dev/null | fgrep __cpp_alias_templates

always fails, because it silently invokes the C-drivers (as if invoked by gcc). You can see this by comparing its output against that of gcc or by adding a g++-specific command line option like (-std=c++11) which emits the error message cc1: warning: command line option ‘-std=c++11’ is valid for C++/ObjC++ but not for C.

Because (the non C++) gcc will never support "Templates Aliases" (see http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2258.pdf) you must add the -x c++ option to force the invocation of the C++ compiler (Credits for using the -x c++ options instead of an empty dummy file go to yuyichao, see below):

g++ -dM -E -x c++ /dev/null | fgrep __cpp_alias_templates

There will be no output because g++ (revision 4.9.1, defaults to -std=gnu++98) does not enable C++11-features by default. To do so, use

g++ -dM -E -x c++ -std=c++11 /dev/null | fgrep __cpp_alias_templates

which finally yields

#define __cpp_alias_templates 200704

noting that g++ 4.9.1 does support "Templates Aliases" when invoked with -std=c++11.

IF OBJECT_ID('master..test') is not null Drop table test

CREATE TABLE test (ID INTEGER, NAME VARCHAR (50), VALUE INTEGER );
INSERT INTO test VALUES (1, 'A', 4);
INSERT INTO test VALUES (1, 'A', 5);
INSERT INTO test VALUES (1, 'B', 8);
INSERT INTO test VALUES (2, 'C', 9);

select distinct NAME , LIST = Replace(Replace(Stuff((select ',', +Value from test where name = _a.name for xml path('')), 1,1,''),'<Value>', ''),'</Value>','') from test _a order by 1 desc

My table name is test , and for concatination I use the For XML Path('') syntax. The stuff function inserts a string into another string. It deletes a specified length of characters in the first string at the start position and then inserts the second string into the first string at the start position.

STUFF functions looks like this : STUFF (character_expression , start , length ,character_expression )

character_expression Is an expression of character data. character_expression can be a constant, variable, or column of either character or binary data.

start Is an integer value that specifies the location to start deletion and insertion. If start or length is negative, a null string is returned. If start is longer than the first character_expression, a null string is returned. start can be of type bigint.

length Is an integer that specifies the number of characters to delete. If length is longer than the first character_expression, deletion occurs up to the last character in the last character_expression. length can be of type bigint.

As stated in the other answers:

• MOV will grab the data at the address inside the brackets and place that data into the destination operand.
• LEA will perform the calculation of the address inside the brackets and place that calculated address into the destination operand. This happens without actually going out to the memory and getting the data. The work done by LEA is in the calculating of the "effective address".

Because memory can be addressed in several different ways (see examples below), LEA is sometimes used to add or multiply registers together without using an explicit ADD or MUL instruction (or equivalent).

Since everyone is showing examples in Intel syntax, here are some in AT&T syntax:

MOVL 16(%ebp), %eax       /* put long  at  ebp+16  into eax */
LEAL 16(%ebp), %eax       /* add 16 to ebp and store in eax */

MOVQ (%rdx,%rcx,8), %rax  /* put qword at  rcx*8 + rdx  into rax */
LEAQ (%rdx,%rcx,8), %rax  /* put value of "rcx*8 + rdx" into rax */

MOVW 5(%bp,%si), %ax      /* put word  at  si + bp + 5  into ax */
LEAW 5(%bp,%si), %ax      /* put value of "si + bp + 5" into ax */

MOVQ 16(%rip), %rax       /* put qword at rip + 16 into rax                 */
LEAQ 16(%rip), %rax       /* add 16 to instruction pointer and store in rax */

MOVL label(,1), %eax      /* put long at label into eax            */
LEAL label(,1), %eax      /* put the address of the label into eax */

To run a single test method in Maven, you need to provide the command as:

mvn test -Dtest=TestCircle#xyz test

where TestCircle is the test class name and xyz is the test method.

Wild card characters also work; both in the method name and class name.

If you're testing in a multi-module project, specify the module that the test is in with -pl <module-name>.

For integration tests use it.test=... option instead of test=...:

mvn -pl <module-name> -Dit.test=TestCircle#xyz integration-test

Implement your Dropdown as

<select id = "dropdown" ref = {(input)=> this.menu = input}>
    <option value="N/A">N/A</option>
    <option value="1">1</option>
    <option value="2">2</option>
    <option value="3">3</option>
    <option value="4">4</option>
</select>

Now, to obtain the selected option value of the dropdown menu just use:

let res = this.menu.value;

You could read the entire input line from scanner, then split the line by , then you have a String[], parse each number into int[] with index one to one matching...(assuming valid input and no NumberFormatExceptions) like

String line = scanner.nextLine();
String[] numberStrs = line.split(",");
int[] numbers = new int[numberStrs.length];
for(int i = 0;i < numberStrs.length;i++)
{
   // Note that this is assuming valid input
   // If you want to check then add a try/catch 
   // and another index for the numbers if to continue adding the others (see below)
   numbers[i] = Integer.parseInt(numberStrs[i]);
}

As YoYo's answer suggests, the above can be achieved more concisely in Java 8:

int[] numbers = Arrays.stream(line.split(",")).mapToInt(Integer::parseInt).toArray();  

To handle invalid input

You will need to consider what you want need to do in this case, do you want to know that there was bad input at that element or just skip it.

If you don't need to know about invalid input but just want to continue parsing the array you could do the following:

int index = 0;
for(int i = 0;i < numberStrs.length;i++)
{
    try
    {
        numbers[index] = Integer.parseInt(numberStrs[i]);
        index++;
    }
    catch (NumberFormatException nfe)
    {
        //Do nothing or you could print error if you want
    }
}
// Now there will be a number of 'invalid' elements 
// at the end which will need to be trimmed
numbers = Arrays.copyOf(numbers, index);

The reason we should trim the resulting array is that the invalid elements at the end of the int[] will be represented by a 0, these need to be removed in order to differentiate between a valid input value of 0.

Results in

Input: "2,5,6,bad,10"
Output: [2,3,6,10]

If you need to know about invalid input later you could do the following:

Integer[] numbers = new Integer[numberStrs.length];
for(int i = 0;i < numberStrs.length;i++)        
{
    try 
    {
        numbers[i] = Integer.parseInt(numberStrs[i]);
    }
    catch (NumberFormatException nfe)   
    {
        numbers[i] = null;
    }
}

In this case bad input (not a valid integer) the element will be null.

Results in

Input: "2,5,6,bad,10"
Output: [2,3,6,null,10]

You could potentially improve performance by not catching the exception (see this question for more on this) and use a different method to check for valid integers.

For example:

String myInput = null;
Scanner myscan = new Scanner(System.in).useDelimiter("\\n");
System.out.println("Enter your input: ");
myInput = myscan.next();
System.out.println(myInput);

This will let you use Enter as a delimiter.

Thus, if you input:

Hello world (ENTER)

it will print 'Hello World'.

As you stated in the comments, some of the values appeared to be floats, not strings. You will need to change it to strings before passing it to re.sub. The simplest way is to change location to str(location) when using re.sub. It wouldn't hurt to do it anyways even if it's already a str.

letters_only = re.sub("[^a-zA-Z]",  # Search for all non-letters
                          " ",          # Replace all non-letters with spaces
                          str(location))

If you want to pass the cookie to the browser, you have to append to the headers to be sent back. If you're using wsgi:

import requests
...


def application(environ, start_response):
    cookie = {'enwiki_session': '17ab96bd8ffbe8ca58a78657a918558'}
    response_headers = [('Content-type', 'text/plain')]
    response_headers.append(('Set-Cookie',cookie))
...

    return [bytes(post_env),response_headers]

I'm successfully able to authenticate with Bugzilla and TWiki hosted on the same domain my python wsgi script is running by passing auth user/password to my python script and pass the cookies to the browser. This allows me to open the Bugzilla and TWiki pages in the same browser and be authenticated. I'm trying to do the same with SuiteCRM but i'm having trouble with SuiteCRM accepting the session cookies obtained from the python script even though it has successfully authenticated.

df_buy['BUY'] = df_buy['BUY'].astype('float')
df_buy['BUY'] = ['€ {:,.2f}'.format(i) for i in list(df_buy['BUY'])]

Hit this to exchange a short living access token for a long living/non expiring(pages) one:

https://graph.facebook.com/oauth/access_token?             
    client_id=APP_ID&
    client_secret=APP_SECRET&
    grant_type=fb_exchange_token&
    fb_exchange_token=EXISTING_ACCESS_TOKEN 

string::c.str() returns a string of type const char * as seen here

A quick fix: try casting printfunc(num,addr,(char *)data.str().c_str());

While the above may work, it is undefined behaviour, and unsafe.

Here's a nicer solution using templates:

char * my_argument = const_cast<char*> ( ...c_str() );

PHP > 5.3 use fgetcsv() or str_getcsv(). Couldn't be simpler.

One more thing to watch out for is if the second value was another Integer object instead of a literal '0', the '==' operator compares the object pointers and will not auto-unbox.

ie:

Integer a = new Integer(0);   
Integer b = new Integer(0);   
int c = 0;

boolean isSame_EqOperator = (a==b); //false!
boolean isSame_EqMethod = (a.equals(b)); //true
boolean isSame_EqAutoUnbox = ((a==c) && (a.equals(c)); //also true, because of auto-unbox

//Note: for initializing a and b, the Integer constructor 
// is called explicitly to avoid integer object caching 
// for the purpose of the example.
// Calling it explicitly ensures each integer is created 
// as a separate object as intended.
// Edited in response to comment by @nolith

You have to use absolute path in this case. But if you set the CopyToOutputDirectory = CopyAlways, it will work as you are doing it.

You can just set the min-width in the css, for example:

.someClass{min-width: 980px;}

It will not break, nevertheless you will still have the scroll-bar to deal with.

function getVimeoInfo($link)
 {
    if (preg_match('~^http://(?:www\.)?vimeo\.com/(?:clip:)?(\d+)~', $link, $match)) 
    {
        $id = $match[1];
    }
    else
    {
        $id = substr($link,10,strlen($link));
    }

    if (!function_exists('curl_init')) die('CURL is not installed!');
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, "http://vimeo.com/api/v2/video/$id.php");
    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_TIMEOUT, 10);
    $output = unserialize(curl_exec($ch));
    $output = $output[0];
    curl_close($ch);
    return $output;
}`

//at below function pass the thumbnail url.

function save_image_local($thumbnail_url)
    {

         //for save image at local server
         $filename = time().'_hbk.jpg';
         $fullpath = '../../app/webroot/img/videos/image/'.$filename;

         file_put_contents ($fullpath,file_get_contents($thumbnail_url));

        return $filename;
    }

That's HTML, but yes, you can bang pretty much any selectors you like together.

#x.y { }

(And the HTML is fine too)

$.each() works for objects and arrays both:

var data = { "programs": [ { "name":"zonealarm", "price":"500" }, { "name":"kaspersky", "price":"200" } ] };

$.each(data.programs, function (i) {
    $.each(data.programs[i], function (key, val) {
        alert(key + val);
    });
});

...and since you will get the current array element as second argument:

$.each(data.programs, function (i, currProgram) {
    $.each(currProgram, function (key, val) {
        alert(key + val);
    });
});

public void addNotification()
{
    NotificationCompat.Builder mBuilder=new NotificationCompat.Builder(MainActivity.this);
    mBuilder.setSmallIcon(R.drawable.email);
    mBuilder.setContentTitle("Notification Alert, Click Me!");
    mBuilder.setContentText("Hi,This notification for you let me check");
    Intent notificationIntent = new Intent(this,MainActivity.class);
    PendingIntent conPendingIntent = PendingIntent.getActivity(this,0,notificationIntent,PendingIntent.FLAG_UPDATE_CURRENT);

    mBuilder.setContentIntent(conPendingIntent);

    NotificationManager manager=(NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
    manager.notify(0,mBuilder.build());
    Toast.makeText(MainActivity.this, "Notification", Toast.LENGTH_SHORT).show();

}

I got this error when my server process got an exception midway during generating the response and simply closed the connection without saying goodbye. curl still expected data from the connection and complained (rightfully).

For me, the model was fine. It was because I had 2 different versions of entity framework. One version for the web project and another one for the common project which contains the models.

I just had to consolidate the nuget packages.

Enjoy!

Symfony is smart and knows how to make the find() by itself :

public function deleteGuestAction(Guest $guest)
{
    if (!$guest) {
        throw $this->createNotFoundException('No guest found');
    }

    $em = $this->getDoctrine()->getEntityManager();
    $em->remove($guest);
    $em->flush();

    return $this->redirect($this->generateUrl('GuestBundle:Page:viewGuests.html.twig'));
}

To send the id in your controller, use {{ path('your_route', {'id': guest.id}) }}

Suppose we have column with alphanumeric field having entries like

a41q
1458
xwe8
1475
asde
9582
.
.
.
.
.
qe84

and you want highest numeric value from this db column (in this case it is 9582) then this query will help you

SELECT Max(column_name) from table_name where column_name REGEXP '^[0-9]+$'

Go to Order and export from project properties and make sure you're including the required jars in the export, this did it for me

Source : Send email in ASP.NET C#

Below is a sample working code for sending in a mail using C#, in the below example I am using google’s smtp server.

The code is pretty self explanatory, replace email and password with your email and password values.

public void SendEmail(string address, string subject, string message)
{
    string email = "[email protected]";
    string password = "put-your-GMAIL-password-here";

    var loginInfo = new NetworkCredential(email, password);
    var msg = new MailMessage();
    var smtpClient = new SmtpClient("smtp.gmail.com", 587);

    msg.From = new MailAddress(email);
    msg.To.Add(new MailAddress(address));
    msg.Subject = subject;
    msg.Body = message;
    msg.IsBodyHtml = true;

    smtpClient.EnableSsl = true;
    smtpClient.UseDefaultCredentials = false;
    smtpClient.Credentials = loginInfo;
    smtpClient.Send(msg);
}

The main problem is that:

in a constructor, the injection of the dependencies has not yet occurred*

_{*obviously excluding Constructor Injection}

Real-world example:

public class Foo {

    @Inject
    Logger LOG;

    @PostConstruct
    public void fooInit(){
        LOG.info("This will be printed; LOG has already been injected");
    }

    public Foo() {
        LOG.info("This will NOT be printed, LOG is still null");
        // NullPointerException will be thrown here
    }
}

IMPORTANT: @PostConstruct and @PreDestroy have been completely removed in Java 11.

To keep using them, you'll need to add the javax.annotation-api JAR to your dependencies.

Maven

<!-- https://mvnrepository.com/artifact/javax.annotation/javax.annotation-api -->
<dependency>
    <groupId>javax.annotation</groupId>
    <artifactId>javax.annotation-api</artifactId>
    <version>1.3.2</version>
</dependency>

Gradle

// https://mvnrepository.com/artifact/javax.annotation/javax.annotation-api
compile group: 'javax.annotation', name: 'javax.annotation-api', version: '1.3.2'

Use g++ -std=c++11 -o <output_file_name> <file_to_be_compiled>

You might also consider the smart_open module, which supports iterators:

from smart_open import smart_open

# stream lines from an S3 object
for line in smart_open('s3://mybucket/mykey.txt', 'rb'):
    print(line.decode('utf8'))

and context managers:

with smart_open('s3://mybucket/mykey.txt', 'rb') as s3_source:
    for line in s3_source:
         print(line.decode('utf8'))

    s3_source.seek(0)  # seek to the beginning
    b1000 = s3_source.read(1000)  # read 1000 bytes
