I believe it is more to do with how your network is configured. Servlet is simply giving you the address it is finding.

I can suggest two workarounds. First try using IPV4. See this SO Answer

Also, try using the request.getRemoteHost() method to get the names of the machines. Surely the names are independent of whatever IP they are mapped to.

I still think you should discuss this with your infrastructure guys.

I'm not sure this is so surprising. Most people who code in PHP are not well versed in what PHP is actually doing at the bare metal. I'll state a few things, which will be true most of the time:

1. If you're not modifying the variable, by-value is faster in PHP. This is because it's reference counted anyway and by-value gives it less to do. It knows the second you modify that ZVAL (PHP's internal data structure for most types), it will have to break it off in a straightforward way (copy it and forget about the other ZVAL). But you never modify it, so it doesn't matter. References make that more complicated with more bookkeeping it has to do to know what to do when you modify the variable. So if you're read-only, paradoxically it's better not the point that out with the &. I know, it's counter intuitive, but it's also true.

2. Foreach isn't slow. And for simple iteration, the condition it's testing against — "am I at the end of this array" — is done using native code, not PHP opcodes. Even if it's APC cached opcodes, it's still slower than a bunch of native operations done at the bare metal.

3. Using a for loop "for ($i=0; $i < count($x); $i++) is slow because of the count(), and the lack of PHP's ability (or really any interpreted language) to evaluate at parse time whether anything modifies the array. This prevents it from evaluating the count once.

4. But even once you fix it with "$c=count($x); for ($i=0; $i<$c; $i++) the $i<$c is a bunch of Zend opcodes at best, as is the $i++. In the course of 100000 iterations, this can matter. Foreach knows at the native level what to do. No PHP opcodes needed to test the "am I at the end of this array" condition.

5. What about the old school "while(list(" stuff? Well, using each(), current(), etc. are all going to involve at least 1 function call, which isn't slow, but not free. Yes, those are PHP opcodes again! So while + list + each has its costs as well.

For these reasons foreach is understandably the best option for simple iteration.

And don't forget, it's also the easiest to read, so it's win-win.

create an xml gradient.xml file under drawable folder

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item>
        <shape android:shape="rectangle"  >
            <corners android:radius="50dip" />
            <stroke android:width="1dip" android:color="#667162" />
            <gradient android:angle="-90" android:startColor="#ffffff" android:endColor="#ffffff" />
        </shape>
    </item>
</selector>

then add this to your TextView

android:background="@drawable/gradient"

Basically speaking, both of them are very closely related to each other.

Consider Iterator to be an interface which helps us in traversing through a collection with the help of some undefined methods like hasNext(), next() and remove()

On the flip side, Iterable is another interface, which, if implemented by a class forces the class to be Iterable and is a target for For-Each construct. It has only one method named iterator() which comes from Iterator interface itself.

When a collection is iterable, then it can be iterated using an iterator.

For understanding visit these:

ITERABLE: http://grepcode.com/file/repository.grepcode.com/java/root/jdk/openjdk/6-b14/java/lang/Iterable.java

UPDATE
(Given the upvotes, I feel there is a need for a complete step-by-step explanation...)

1. In the Menu bar click on File->Open Folder...
2. Select a folder (the actual folder does not really matter, this step is just to make the FOLDERS sidebar available)
3. If there is no Side Bar shown yet, make it appear via View -> Side Bar -> Show Side Bar
4. Use this FOLDERS-titled Side Bar to navigate to the first file you want to compare.
5. Select it (click on it), hold down ctrl and select the second file.
6. Having two files selected, right click on one of the two and select Diff Files...

There should be a new Tab now showing the comparison.

Original short answer:
Note that:

The "Diff files" only appears with the "folders" sidebar (to open a folder: File->Open Folder) , not with "open files" sidebar.

I am updating a simple solution. First add an id to your segue which presents modal. Than in properties change it's presentation style to "Over Current Context". Than add this code in presenting view controller (The controller which is presenting modal).

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
    let Device = UIDevice.currentDevice()

    let iosVersion = NSString(string: Device.systemVersion).doubleValue

    let iOS8 = iosVersion >= 8
    let iOS7 = iosVersion >= 7 && iosVersion < 8
    if((segue.identifier == "chatTable")){

    if (iOS8){


          }
        else {

            self.navigationController?.modalPresentationStyle = UIModalPresentationStyle.CurrentContext


        }
    }
}

Make sure you change segue.identifier to your own id ;)

I got this error but it is resolved interesting. As first, i got this error at api level 17. When i call a thread (AsyncTask or others) without progress dialog then i call an other thread method again using progress dialog, i got that crash and the reason is about usage of progress dialog.

In my case, there are two results that;

• I took show(); method of progress dialog before first thread starts then i took dismiss(); method of progress dialog before last thread ends.

So :

ProgresDialog progressDialog = new ...

//configure progressDialog 

progressDialog.show();

start firstThread {
...
}

...

start lastThread {
...
} 

//be sure to finish threads

progressDialog.dismiss();

• This is so strange but that error has an ability about destroy itself at least for me :)

Bootstrap comes with many pre-build classes and one of them is class="text-left". Please call this class whenever needed. :-)

Once you have the initial ul, you can use the children() method, which will only consider the immediate children of the element. As @activa points out, one way to easily select the root element is to give it a class or an id. The following assumes you have a root ul with id root.

$('ul#root').children('li');

In 2021 you should install wrapper:

ansible-galaxy collection install ansible.posix

And use

- name: Synchronize two directories on one remote host.
  ansible.posix.synchronize:
    src: /first/absolute/path
    dest: /second/absolute/path
  delegate_to: "{{ inventory_hostname }}"

Read more:

https://docs.ansible.com/ansible/latest/collections/ansible/posix/synchronize_module.html

Checked on:

ansible --version                          
ansible 2.10.5

  executable location = /sbin/ansible
  python version = 3.9.1 (default, Dec 13 2020, 11:55:53) [GCC 10.2.0]

That should do the trick:

echo `pwd`/`dirname $0`

It might look ugly depending on how it was invoked and the cwd but should get you where you need to go (or you can tweak the string if you care how it looks).

I just solved this problem :

• Class-based Projections doesn't work with query native(@Query(value = "SELECT ...", nativeQuery = true)) so I recommend to define custom DTO using interface .
• Before using DTO should verify the query syntatically correct or not

One solution I adopted--for use with java code, but the concept is the same with mexFunctions, just messier--is to return a FutureValue and then loop while FutureValue.finished() or whatever returns true. The actual code executes in another thread/process. Wrapping a try,catch around that and a FutureValue.cancel() in the catch block works for me.

In the case of mex functions, you will need to return somesort of pointer (as an int) that points to a struct/object that has all the data you need (native thread handler, bool for complete etc). In the case of a built in mexFunction, your mexFunction will most likely need to call that mexFunction in the separate thread. Mex functions are just DLLs/shared objects after all.

PseudoCode

FV = mexLongProcessInAnotherThread();
try
  while ~mexIsDone(FV);
    java.lang.Thread.sleep(100); %pause has a memory leak
    drawnow; %allow stdout/err from mex to display in command window
  end
catch
  mexCancel(FV);
end

You should add the g modifier so that sed performs a global substitution of the contents of the pattern buffer:

echo dog dog dos | sed -e 's:dog:log:g'

For a fantastic documentation on sed, check http://www.grymoire.com/Unix/Sed.html. This global flag is explained here: http://www.grymoire.com/Unix/Sed.html#uh-6

The official documentation for GNU sed is available at http://www.gnu.org/software/sed/manual/

I came across this question while searching for a way to pick out the first item in one array that does not match any of the values in another array and managed to sort it out eventually with array.find() and array.filter() like this

var carList= ['mercedes', 'lamborghini', 'bmw', 'honda', 'chrysler'];
var declinedOptions = ['mercedes', 'lamborghini'];

const nextOption = carList.find(car=>{
    const duplicate = declinedOptions.filter(declined=> {
      return declined === car
    })
    console.log('duplicate:',duplicate) //should list out each declined option
    if(duplicate.length === 0){//if theres no duplicate, thats the nextOption
      return car
    }
})

console.log('nextOption:', nextOption);
//expected outputs
//duplicate: mercedes
//duplicate: lamborghini
//duplicate: []
//nextOption: bmw

if you need to keep fetching an updated list before cross-checking for the next best option this should work well enough :)

There is a simple way to find the date from any birthdate by using substr of PHP

$birth_date = '15.03.2014';
$date = substr($birth_date, 0, 2);
echo $date;

Which will just simply give you the output date of that birth date.

In this case, that will be 15.

See substr of PHP for more...

The simplest solution is to apply Python str function to the column you are trying to loop through.

If you are using pandas, this can be implemented as:

dataframe['column_name']=dataframe['column_name'].apply(str)

Yes, there's a command git commit --amend which is used to "fix" last commit.

In your case it would be called as:

git add the_left_out_file
git commit --amend --no-edit

The --no-edit flag allow to make amendment to commit without changing commit message.

EDIT: Warning You should never amend public commits, that you already pushed to public repository, because what amend does is actually removing from history last commit and creating new commit with combined changes from that commit and new added when amending.

If for example your toggle-able icon is visible only for extra small devices, then you could do something like this:

$('[data-toggle="offcanvas"]').click(function () {
    $('#side-menu').toggleClass('hidden-xs');
});

Clicking [data-toggle="offcanvas"] will add bootstrap's .hidden-xs to my #side-menu which will hide the side-menu content, but will become visible again if you increase the window size.

The setting for the list throttle

• Open the SharePoint Central Administration,
• go to Application Management --> Manage Web Applications
• Click to select the web application that hosts your list (eg. SharePoint - 80)
• At the Ribbon, select the General Settings and select Resource Throttling
• Then, you can see the 5000 List View Threshold limit and you can edit the value you want.
• Click OK to save it.

If you want to check if a string contains substring or not using regex, the closest you can do is by using find() -

    private static final validPattern =   "\\bstores\\b.*\\bstore\\b.*\\bproduct\\b"
    Pattern pattern = Pattern.compile(validPattern);
    Matcher matcher = pattern.matcher(inputString);
    System.out.print(matcher.find()); // should print true or false.

Note the difference between matches() and find(), matches() return true if the whole string matches the given pattern. find() tries to find a substring that matches the pattern in a given input string. Also by using find() you don't have to add extra matching like - (?s).* at the beginning and .* at the end of your regex pattern.

I've finally solved a very similar issue!

In my case, the problem was that I had two different SDKs (one from Eclipse and the other from Android Studio), so I was trying to execute the ADB commands in the wrong one.

So it is important that you check the path you are using in your IDE and execute the commands on the same.

The latest JDBC MSSQL connectivity driver can be found on JDBC 4.0

The class file should be in the classpath. If you are using eclipse you can easily do the same by doing the following -->

Right Click Project Name --> Properties --> Java Build Path --> Libraries --> Add External Jars

Also as already been pointed out by @Cheeso the correct way to access is jdbc:sqlserver://server:port;DatabaseName=dbname

Meanwhile please find a sample class for accessing MSSQL DB (2008 in my case).

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;

public class ConnectMSSQLServer
{
   public void dbConnect(String db_connect_string,
            String db_userid,
            String db_password)
   {
      try {
         Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
         Connection conn = DriverManager.getConnection(db_connect_string,
                  db_userid, db_password);
         System.out.println("connected");
         Statement statement = conn.createStatement();
         String queryString = "select * from SampleTable";
         ResultSet rs = statement.executeQuery(queryString);
         while (rs.next()) {
            System.out.println(rs.getString(1));
         }
         conn.close();
      } catch (Exception e) {
         e.printStackTrace();
      }
   }

   public static void main(String[] args)
   {
      ConnectMSSQLServer connServer = new ConnectMSSQLServer();
      connServer.dbConnect("jdbc:sqlserver://xx.xx.xx.xxxx:1433;databaseName=MyDBName", "DB_USER","DB_PASSWORD");
   }
}

Hope this helps.

I also tried to use CURRVAL, in my case to find out if some process inserted new rows to some table with that sequence as Primary Key. My assumption was that CURRVAL would be the fastest method. But a) CurrVal does not work, it will just get the old value because you are in another Oracle session, until you do a NEXTVAL in your own session. And b) a select max(PK) from TheTable is also very fast, probably because a PK is always indexed. Or select count(*) from TheTable. I am still experimenting, but both SELECTs seem fast.

I don't mind a gap in a sequence, but in my case I was thinking of polling a lot, and I would hate the idea of very large gaps. Especially if a simple SELECT would be just as fast.

Conclusion:

• CURRVAL is pretty useless, as it does not detect NEXTVAL from another session, it only returns what you already knew from your previous NEXTVAL
• SELECT MAX(...) FROM ... is a good solution, simple and fast, assuming your sequence is linked to that table

EDIT: Looking at the replies so far, it seems that Tortoise will only do it right if it's a file that's already versioned. That's not the case here. I need to be able to apply a patch to a file that did not come out of an SVN repository. I just tried using Tortoise because I happen to know that SVN uses diffs and has to know how to both create them and apply them.

You can install Cygwin, then use the command-line patch tool to apply the patch. See also this Unix man page, which applies to patch.

The above didn't actually work for me as I had expected with Visual Studio 2010. It wouldn't let me access Properties.Resources, said it was inaccessible due to permission issues. I ultimately had to change the Persistence settings in the properties of the resource and then I found how to access it via the Resources.Designer.cs file, where it had an automatic getter that let me access the icon, via MyNamespace.Properties.Resources.NameFromAddingTheResource. That returns an object of type Icon, ready to just use.

npm install now supports this

npm install --save ../path/to/mymodule

For this to work mymodule must be configured as a module with its own package.json. See Creating NodeJS modules.

As of npm 2.0, local dependencies are supported natively. See danilopopeye's answer to a similar question. I've copied his response here as this question ranks very high in web search results.

This feature was implemented in the version 2.0.0 of npm. For example:

{
  "name": "baz",
  "dependencies": {
    "bar": "file:../foo/bar"
  }
}

Any of the following paths are also valid:

../foo/bar
~/foo/bar
./foo/bar
/foo/bar

syncing updates

Since npm install copies mymodule into node_modules, changes in mymodule's source will not automatically be seen by the dependent project.

There are two ways to update the dependent project with

• Update the version of mymodule and then use npm update: As you can see above, the package.json "dependencies" entry does not include a version specifier as you would see for normal dependencies. Instead, for local dependencies, npm update just tries to make sure the latest version is installed, as determined by mymodule's package.json. See chriskelly's answer to this specific problem.

• Reinstall using npm install. This will install whatever is at mymodule's source path, even if it is older, or has an alternate branch checked out, whatever.

From another search. Worked for me!

"You can use Visual Studio 2010 and it does support it, provided your OS supports .NET 4.5.

Right click on your solution to add a reference (as you do). When the dialog box shows, select browse, then navigate to the following folder:

C:\Program Files(x86)\Reference Assemblies\Microsoft\Framework\.Net Framework\4.5

You will find it there."

When the workbook first opens, execute this code:

alertTime = Now + TimeValue("00:02:00")
Application.OnTime alertTime, "EventMacro"

Then just have a macro in the workbook called "EventMacro" that will repeat it.

Public Sub EventMacro()
    '... Execute your actions here'
    alertTime = Now + TimeValue("00:02:00")
    Application.OnTime alertTime, "EventMacro"
End Sub

This worked for me:

var backgroundColor = window.getComputedStyle ? window.getComputedStyle(myDiv, null).getPropertyValue("background-color") : myDiv.style.backgroundColor;

And, even better:

var getStyle = function(element, property) {
    return window.getComputedStyle ? window.getComputedStyle(element, null).getPropertyValue(property) : element.style[property.replace(/-([a-z])/g, function (g) { return g[1].toUpperCase(); })];
};
var backgroundColor = getStyle(myDiv, "background-color");

If you want the first line and then you want to perform some operation on file this code will helpful.

with open(filename , 'r') as f:
    first_line = f.readline()
    for line in f:
            # Perform some operations

You can do the following:

echo '<div class="my_class">';
echo ($cart->count_product > 0) ? $cart->count_product : '';
echo '</div>';

If you want to have it inside your statement, do this:

if($cart->count_product > 0) 
{
    echo '<div class="my_class">'.$cart->count_product.'</div>';
}

You don't need the else statement, since you're only going to output the above when it's truthy anyway.

A string-oriented alternative, that uses an array:

spec=(IGNORE REPLACE)
for p in {13..15}; do
  echo "$p: ${spec[p==14]}";
done

which outputs:

13: IGNORE
14: REPLACE
15: IGNORE

I am not exactly sure which part to blame, but here's why MemoryStream doesn't work for you:

As you write to MemoryStream, it increments it's Position property. The constructor of StreamContent takes into account the stream's current Position. So if you write to the stream, then pass it to StreamContent, the response will start from the nothingness at the end of the stream.

There's two ways to properly fix this:

1) construct content, write to stream

[HttpGet]
public HttpResponseMessage Test()
{
    var stream = new MemoryStream();
    var response = Request.CreateResponse(HttpStatusCode.OK);
    response.Content = new StreamContent(stream);
    // ...
    // stream.Write(...);
    // ...
    return response;
}

2) write to stream, reset position, construct content

[HttpGet]
public HttpResponseMessage Test()
{
    var stream = new MemoryStream();
    // ...
    // stream.Write(...);
    // ...
    stream.Position = 0;

    var response = Request.CreateResponse(HttpStatusCode.OK);
    response.Content = new StreamContent(stream);
    return response;
}

2) looks a little better if you have a fresh Stream, 1) is simpler if your stream does not start at 0

Swift 4.2

For multiple selections you need to set the UITableView property allowsMultipleSelection to true.

myTableView.allowsMultipleSelection = true

In case you subclassed the UITableViewCell, you override setSelected(_ selected: Bool, animated: Bool) method in your custom cell class.

 override func setSelected(_ selected: Bool, animated: Bool) {
     super.setSelected(selected, animated: animated)

     if selected {
         contentView.backgroundColor = UIColor.green
     } else {
         contentView.backgroundColor = UIColor.blue
     }
 }

Use pandas and the json library:

import pandas as pd
import json
filepath = "inputfile.csv"
output_path = "outputfile.json"

df = pd.read_csv(filepath)

# Create a multiline json
json_list = json.loads(df.to_json(orient = "records"))

with open(output_path, 'w') as f:
    for item in json_list:
        f.write("%s\n" % item)

Another one simple method is there. You don't need to code more in CSS. Just including a java script and entering the div "id" inside the script you can get equal height of columns so that you can have the height fit to container. It works in major browsers.

            {
                if (i > j)
                {
                    return true;
                }
                char a = value[i];
                char b = value[j];
                if (char.ToLower(a) != char.ToLower(b))
                {
                    return false;
                }
                i++;
                j--;
            }
        }

I eventually figured out an easy way to do it:

1. On your Twitter feed, click the date/time of the tweet containing the video. That will open the single tweet view
2. Look for the down-pointing arrow at the top-right corner of the tweet, click it to open drop-down menue
3. Select the "Embed Video" option and copy the HTML embed code and Paste it to Notepad
4. Find the last "t.co" shortened URL inside the HTML code (should be something like this: https://``t.co/tQM43ftXyM). Copy this URL and paste it in a new browser tab.
5. The browser will expand the shortened URL to something which looks like this: https://twitter.com/UserName/status/828267001496784896/video/1

This is the link to the Twitter Card containing the native video. Pasting this link in a new tweet or DM will include the native video in it!

Try this:

public static void main(String[] args) {
    String str = "My name is Milan, people know me as Milan Vasic.";

    Pattern p = Pattern.compile("(Milan)(?! Vasic)");
    Matcher m = p.matcher(str);

    StringBuffer sb = new StringBuffer();

    while(m.find()) {
        m.appendReplacement(sb, "Milan Vasic");
    }

    m.appendTail(sb);
    System.out.println(sb);
}

Try this:

window.location.href = "http://www.gorissen.info/Pierre/maps/googleMapLocation.php?lat=\''+elemA+'\'&lon=\''+elemB+'\'&setLatLon=Set";

This question is old, the other answers are old. "Employed Russian"s answer is very good and informative, but it only works if you have the source code. If you don't, the alternatives back then were very tricky. Fortunately nowadays we have a simple solution to this problem (as commented in one of his replies), using patchelf. All you have to do is:

$ ./patchelf --set-interpreter /path/to/newglibc/ld-linux.so.2 --set-rpath /path/to/newglibc/ myapp

And after that, you can just execute your file:

$ ./myapp

No need to chroot or manually edit binaries, thankfully. But remember to backup your binary before patching it, if you're not sure what you're doing, because it modifies your binary file. After you patch it, you can't restore the old path to interpreter/rpath. If it doesn't work, you'll have to keep patching it until you find the path that will actually work... Well, it doesn't have to be a trial-and-error process. For example, in OP's example, he needed GLIBC_2.3, so you can easily find which lib provides that version using strings:

$ strings /lib/i686/libc.so.6 | grep GLIBC_2.3
$ strings /path/to/newglib/libc.so.6 | grep GLIBC_2.3

In theory, the first grep would come empty because the system libc doesn't have the version he wants, and the 2nd one should output GLIBC_2.3 because it has the version myapp is using, so we know we can patchelf our binary using that path. If you get a segmentation fault, read the note at the end.

When you try to run a binary in linux, the binary tries to load the linker, then the libraries, and they should all be in the path and/or in the right place. If your problem is with the linker and you want to find out which path your binary is looking for, you can find out with this command:

$ readelf -l myapp | grep interpreter
  [Requesting program interpreter: /lib/ld-linux.so.2]                                                                                                                                                                                   

If your problem is with the libs, commands that will give you the libs being used are:

$ readelf -d myapp | grep Shared
$ ldd myapp 

This will list the libs that your binary needs, but you probably already know the problematic ones, since they are already yielding errors as in OP's case.

"patchelf" works for many different problems that you may encounter while trying to run a program, related to these 2 problems. For example, if you get: ELF file OS ABI invalid, it may be fixed by setting a new loader (the --set-interpreter part of the command) as I explain here. Another example is for the problem of getting No such file or directory when you run a file that is there and executable, as exemplified here. In that particular case, OP was missing a link to the loader, but maybe in your case you don't have root access and can't create the link. Setting a new interpreter would solve your problem.

Thanks Employed Russian and Michael Pankov for the insight and solution!

Note for segmentation fault: you might be in the case where myapp uses several libs, and most of them are ok but some are not; then you patchelf it to a new dir, and you get segmentation fault. When you patchelf your binary, you change the path of several libs, even if some were originally in a different path. Take a look at my example below:

$ ldd myapp
./myapp: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.20' not found (required by ./myapp)
./myapp: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.21' not found (required by ./myapp)
        linux-vdso.so.1 =>  (0x00007fffb167c000)
        libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f9a9aad2000)
        libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f9a9a8ce000)
        libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f9a9a6af000)
        libstdc++.so.6 => /usr/lib/x86_64-linux-gnu/libstdc++.so.6 (0x00007f9a9a3ab000)
        libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f9a99fe6000)
        /lib64/ld-linux-x86-64.so.2 (0x00007f9a9adeb000)
        libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x00007f9a99dcf000)

Note that most libs are in /lib/x86_64-linux-gnu/ but the problematic one (libstdc++.so.6) is on /usr/lib/x86_64-linux-gnu. After I patchelf'ed myapp to point to /path/to/mylibs, I got segmentation fault. For some reason, the libs are not totally compatible with the binary. Since myapp didn't complain about the original libs, I copied them from /lib/x86_64-linux-gnu/ to /path/to/mylibs2, and I also copied libstdc++.so.6 from /path/to/mylibs there. Then I patchelf'ed it to /path/to/mylibs2, and myapp works now. If your binary uses different libs, and you have different versions, it might happen that you can't fix your situation. :( But if it's possible, mixing libs might be the way. It's not ideal, but maybe it will work. Good luck!

The thread's a little old. But from the title I thought it had promise for my needs. Unfortunately, my structure didn't lend itself easily to the nth-of-type solution. Here's a Thymeleaf solution.

.back-red {
  background-color:red;
}
.back-green {
  background-color:green;
}


<div class="container">
    <div class="row" th:with="employees=${{'emp-01', 'emp-02', 'emp-03', 'emp-04', 'emp-05', 'emp-06', 'emp-07', 'emp-08', 'emp-09', 'emp-10', 'emp-11', 'emp-12'}}">
        <div class="col-md-4 col-sm-6 col-xs-12" th:each="i:${#numbers.sequence(0, #lists.size(employees))}" th:classappend'(${i} % 2) == 0?back-red:back-green"><span th:text="${emplyees[i]}"></span></div>
    </div>
</div>

You can use jQuery UI and do something like this

Html:

<button id="callConfirm">Confirm!</button>

<div id="dialog" title="Confirmation Required">
  Are you sure about this?
</div>?

Javascript:

$("#dialog").dialog({
   autoOpen: false,
   modal: true,
   buttons : {
        "Confirm" : function() {
            alert("You have confirmed!");            
        },
        "Cancel" : function() {
          $(this).dialog("close");
        }
      }
    });

$("#callConfirm").on("click", function(e) {
    e.preventDefault();
    $("#dialog").dialog("open");
});

?

You can use a jQuery plugin: jQuery Array Utilities

For example the code below

$.union([1, 2, 2, 3], [2, 3, 4, 5, 5])

will return [1,2,3,4,5]

There are three method to pass value in php.

• By post
• By get
• By making session variable

These three method are used for different purpose.For example if we want to receive our value on next page then we can use 'post' ($_POST) method as:-

$a=$_POST['field-name'];

If we require the value of variable on more than one page than we can use session variable as:-

$a=$_SESSION['field-name];

Before using this Syntax for creating SESSION variable we first have to add this tag at the very beginning of our php page

session_start(); 

GET method are generally used to print data on same page which used to take input from user. Its syntax is as:

$a=$_GET['field-name'];

POST method are generally consume more secure than GET because when we use Get method than it can display the data in URL bar.If the data is more sensitive data like password then it can be inggeris.

VMDK/VMX are VMWare file formats but you can use it with VirtualBox:

1. Create a new Virtual Machine and when asks for a hard disk choose "Use an existing hard disk"
2. Click on the "button with folder and green arrow image on the combo box right" which opens Virtual Media Manager, it looks like this (you can open it directly pressing CTRL+D on main window or in File > Virtual Media Manager menu)...
3. Then you can add the VMDK/VMX hard disk image and setup it for your virtual machine :)

If you happen to be using Windows 8 and up, here's how to get to it:

• The newer Microsoft SQL Server Configuration Manager is a snap-in for the Microsoft Management Console program.

• It is not a stand-alone program as used in the previous versions of Microsoft Windows operating systems.

• SQL Server Configuration Manager doesn’t appear as an application when running Windows 8.

• To open SQL Server Configuration Manager, in the Search charm, under Apps, type:

  SQLServerManager15.msc for [SQL Server 2019] or

  SQLServerManager14.msc for [SQL Server 2017] or

  SQLServerManager13.msc for [SQL Server 2016] or

  SQLServerManager12.msc for [SQL Server 2014] or

  SQLServerManager11.msc for [SQL Server 2012] or

  SQLServerManager10.msc for [SQL Server 2008], and then press Enter.

Text kindly reproduced from SQL Server Configuration Manager changes in Windows 8

By setting the scale, you decrease the precision. Try NUMBER(16,2).

And you can't use valueOf()?

Edit: Btw, there is nothing stopping you from using static { } in an enum.

If you want to apply the style even after getting struck-trough indication, you can use "!important" to enforce the style. It may not be a right solution but solve the problem.

According to your example here it seems that they both reside in the same namespace, i conclude that they are both part of the same project ( if you haven't created another project with the same namespace) and all class by default are defined as internal to the project they are defined in, if haven't declared otherwise, therefore i guess the problem is that your file is not included in your project. You can include it by right clicking the file in the solution explorer window => Include in project, if you cannot see the file inside the project files in the solution explorer then click the show the upper menu button of the solution explorer called show all files ( just hove your mouse cursor over the button there and you'll see the names of the buttons)

Just for basic knowledge: If the file resides in a different project\ assembly then it has to be defined, otherwise it has to be define at least as internal or public. in case your class is inheriting from that class that it can be protected as well.

Errr, it's a bit messy in the view. But I think I've gotten it to work with group (http://mongoid.org/docs/querying/)

Controller

@event_attendees = Activity.only(:user_id).where(:action => 'Attend').order_by(:created_at.desc).group

View

<% @event_attendees.each do |event_attendee| %>    
  <%= event_attendee['group'].first.user.first_name %>
<% end %>

While JonSkeet's answer explains the difference in a typically excellent way there is another difference: exception handling.

Task.WaitAll throws an AggregateException when any of the tasks throws and you can examine all thrown exceptions. The await in await Task.WhenAll unwraps the AggregateException and 'returns' only the first exception.

When the program below executes with await Task.WhenAll(taskArray) the output is as follows.

19/11/2016 12:18:37 AM: Task 1 started
19/11/2016 12:18:37 AM: Task 3 started
19/11/2016 12:18:37 AM: Task 2 started
Caught Exception in Main at 19/11/2016 12:18:40 AM: Task 1 throwing at 19/11/2016 12:18:38 AM
Done.

When the program below is executed with Task.WaitAll(taskArray) the output is as follows.

19/11/2016 12:19:29 AM: Task 1 started
19/11/2016 12:19:29 AM: Task 2 started
19/11/2016 12:19:29 AM: Task 3 started
Caught AggregateException in Main at 19/11/2016 12:19:32 AM: Task 1 throwing at 19/11/2016 12:19:30 AM
Caught AggregateException in Main at 19/11/2016 12:19:32 AM: Task 2 throwing at 19/11/2016 12:19:31 AM
Caught AggregateException in Main at 19/11/2016 12:19:32 AM: Task 3 throwing at 19/11/2016 12:19:32 AM
Done.

The program:

class MyAmazingProgram
{
    public class CustomException : Exception
    {
        public CustomException(String message) : base(message)
        { }
    }

    static void WaitAndThrow(int id, int waitInMs)
    {
        Console.WriteLine($"{DateTime.UtcNow}: Task {id} started");

        Thread.Sleep(waitInMs);
        throw new CustomException($"Task {id} throwing at {DateTime.UtcNow}");
    }

    static void Main(string[] args)
    {
        Task.Run(async () =>
        {
            await MyAmazingMethodAsync();
        }).Wait();

    }

    static async Task MyAmazingMethodAsync()
    {
        try
        {
            Task[] taskArray = { Task.Factory.StartNew(() => WaitAndThrow(1, 1000)),
                                 Task.Factory.StartNew(() => WaitAndThrow(2, 2000)),
                                 Task.Factory.StartNew(() => WaitAndThrow(3, 3000)) };

            Task.WaitAll(taskArray);
            //await Task.WhenAll(taskArray);
            Console.WriteLine("This isn't going to happen");
        }
        catch (AggregateException ex)
        {
            foreach (var inner in ex.InnerExceptions)
            {
                Console.WriteLine($"Caught AggregateException in Main at {DateTime.UtcNow}: " + inner.Message);
            }
        }
        catch (Exception ex)
        {
            Console.WriteLine($"Caught Exception in Main at {DateTime.UtcNow}: " + ex.Message);
        }
        Console.WriteLine("Done.");
        Console.ReadLine();
    }
}

Use p{width} column specifier: e.g. \begin{tabular}{ l p{10cm} } will put column's content into 10cm-wide parbox, and the text will be properly broken to several lines, like in normal paragraph.

You can also use tabular* environment to specify width for the entire table.

The idea of retrying the query in case of Deadlock exception is good, but it can be terribly slow, since mysql query will keep waiting for locks to be released. And incase of deadlock mysql is trying to find if there is any deadlock, and even after finding out that there is a deadlock, it waits a while before kicking out a thread in order to get out from deadlock situation.

What I did when I faced this situation is to implement locking in your own code, since it is the locking mechanism of mysql is failing due to a bug. So I implemented my own row level locking in my java code:

private HashMap<String, Object> rowIdToRowLockMap = new HashMap<String, Object>();
private final Object hashmapLock = new Object();
public void handleShortCode(Integer rowId)
{
    Object lock = null;
    synchronized(hashmapLock)
    {
      lock = rowIdToRowLockMap.get(rowId);
      if (lock == null)
      {
          rowIdToRowLockMap.put(rowId, lock = new Object());
      }
    }
    synchronized (lock)
    {
        // Execute your queries on row by row id
    }
}

The best solution I have found is:

this.focus();
self.opener=this;
self.close();

If you find the String you are searching for, you can go on for the length of that string (if in case you search aa in aaaa you consider it 2 times).

int c=0;
String found="male cat";
 for(int j=0; j<text.length();j++){
     if(text.contains(found)){
         c+=1;
         j+=found.length()-1;
     }
 }
 System.out.println("counter="+c);

Neither.

Django is a framework, not a language. Python is the language in which Django is written.

Django is a collection of Python libs allowing you to quickly and efficiently create a quality Web application, and is suitable for both frontend and backend.

However, Django is pretty famous for its "Django admin", an auto generated backend that allows you to manage your website in a blink for a lot of simple use cases without having to code much.

More precisely, for the front end, Django helps you with data selection, formatting, and display. It features URL management, a templating language, authentication mechanisms, cache hooks, and various navigation tools such as paginators.

For the backend, Django comes with an ORM that lets you manipulate your data source with ease, forms (an HTML independent implementation) to process user input and validate data and signals, and an implementation of the observer pattern. Plus a tons of use-case specific nifty little tools.

For the rest of the backend work Django doesn't help with, you just use regular Python. Business logic is a pretty broad term.

You probably want to know as well that Django comes with the concept of apps, a self contained pluggable Django library that solves a problem. The Django community is huge, and so there are numerous apps that do specific business logic that vanilla Django doesn't.

Regardless to what is said above, on my ubuntu 16 i had to do :

> split -b 10M -d  system.log system_split.log 

Please note the space between -b and the value

I've never used it but there is a JWT implementation on NuGet.

Package: https://nuget.org/packages/JWT

Source: https://github.com/johnsheehan/jwt

.NET 4.0 compatible: https://www.nuget.org/packages/jose-jwt/

You can also go here: https://jwt.io/ and click "libraries".

It means you should use logging framework like logback or log4j and instead of printing exceptions directly:

e.printStackTrace();

you should log them using this frameworks' API:

log.error("Ops!", e);

Logging frameworks give you a lot of flexibility, e.g. you can choose whether you want to log to console or file - or maybe skip some messages if you find them no longer relevant in some environment.

You can just set it to a class variable and read it from the main program:

class Foo:
    def __init__(self):
        #Do your stuff here
        self.returncode = 42
bar = Foo()
baz = bar.returncode

Primary keys are always indexed by default.

You can define a primary key in SQL Server 2012 by using SQL Server Management Studio or Transact-SQL. Creating a primary key automatically creates a corresponding unique, clustered or nonclustered index.

Try using this tool,which is just a simple js script https://github.com/shashwatsahai/CSSExtractor/ This tool helps in getting the CSS from a specific page listing all sources for active styles and save it to a JSON with source as key and rules as value. It loads all the CSS from the href links and tells all the styles applied from them You can modify the code to save all css into a .css file. Thereby combining all your css.

Already mentioned previously by swilliams, but with an example below (Javascript):

// Function wrapping inner for loop
function CriteriaMatch(record, criteria) {
  for (var k in criteria) {
    if (!(k in record))
      return false;

    if (record[k] != criteria[k])
      return false;
  }

  return true;
}

// Outer for loop implementing continue if inner for loop returns false
var result = [];

for (var i = 0; i < _table.length; i++) {
  var r = _table[i];

  if (!CriteriaMatch(r[i], criteria))
    continue;

  result.add(r);
}

What you are asking is thoroughly covered by Eric Lippert in his blog post Closing over the loop variable considered harmful and its sequel.

For me, the most convincing argument is that having new variable in each iteration would be inconsistent with for(;;) style loop. Would you expect to have a new int i in each iteration of for (int i = 0; i < 10; i++)?

The most common problem with this behavior is making a closure over iteration variable and it has an easy workaround:

foreach (var s in strings)
{
    var s_for_closure = s;
    query = query.Where(i => i.Prop == s_for_closure); // access to modified closure

My blog post about this issue: Closure over foreach variable in C#.

This is possible.

//Create the select list item you want to add
SelectListItem selListItem = new SelectListItem() { Value = "null", Text = "Select One" };

//Create a list of select list items - this will be returned as your select list
List<SelectListItem> newList = new List<SelectListItem>();

//Add select list item to list of selectlistitems
newList.Add(selListItem);

//Return the list of selectlistitems as a selectlist
return new SelectList(newList, "Value", "Text", null);

Played with Boo's approach, however don't like the fact that user got kicked off only once another digest is run, which means user stays logged in until he tries to do something within the page, and then immediatelly kicked off.

I am trying to force the logoff using interval which checks every minute if last action time was more than 30 minutes ago. I hooked it on $routeChangeStart, but could be also hooked on $rootScope.$watch as in Boo's example.

app.run(function($rootScope, $location, $interval) {

    var lastDigestRun = Date.now();
    var idleCheck = $interval(function() {
        var now = Date.now();            
        if (now - lastDigestRun > 30*60*1000) {
           // logout
        }
    }, 60*1000);

    $rootScope.$on('$routeChangeStart', function(evt) {
        lastDigestRun = Date.now();  
    });
});

if you have existing project and you would like to add remote repository url then you need to do following command

git init

if you would like to add readme.md file then you can create it and add it using below command.

git add README.md

make your first commit using below command

git commit -m "first commit"

Now you completed all local repository process, now how you add remote repository url ? check below command this is for ssh url, you can change it for https.

git remote add origin [email protected]:user-name/repository-name.git

How you push your first commit see below command :

git push -u origin master

I can tell you for Windows.

1. Install Java Extension Pack and Code Runner Extension from VS Code Extensions.

2. Edit your java home location in VS Code settings, "java.home": "C:\\Program Files\\Java\\jdk-9.0.4".

3. Check if javac is recognized in VS Code internal terminal. If this check fails, try opening VS Code as administrator.

4. Create a simple Java program in Main.java file as:

public class Main {
    public static void main(String[] args) {
        System.out.println("Hello world");     
    }
}

Note: Do not add package in your main class.

5. Right click anywhere on the java file and select run code.

6. Check the output in the console.

Done, hope this helps.

Try this complete and flexible solution. It works perfectly, and is based in-part by some previous answers, but contains additional validation checks, and gets rid of additional implied HTML from the loadHTML(...) function. It is divided into two separate functions (one with a previous dependency so don't re-order/rearrange) so you can use it with multiple HTML tags that you would like to remove simultaneously (i.e. not just 'script' tags). For example removeAllInstancesOfTag(...) function accepts an array of tag names, or optionally just one as a string. So, without further ado here is the code:

/* Remove all instances of a particular HTML tag (e.g. <script>...</script>) from a variable containing raw HTML data. [BEGIN] */

/* Usage Example: $scriptless_html = removeAllInstancesOfTag($html, 'script'); */

if (!function_exists('removeAllInstancesOfTag'))
    {
        function removeAllInstancesOfTag($html, $tag_nm)
            {
                if (!empty($html))
                    {
                        $html = mb_convert_encoding($html, 'HTML-ENTITIES', 'UTF-8'); /* For UTF-8 Compatibility. */
                        $doc = new DOMDocument();
                        $doc->loadHTML($html,LIBXML_HTML_NOIMPLIED|LIBXML_HTML_NODEFDTD|LIBXML_NOWARNING);

                        if (!empty($tag_nm))
                            {
                                if (is_array($tag_nm))
                                    {
                                        $tag_nms = $tag_nm;
                                        unset($tag_nm);

    };

/* Remove all instances of a particular HTML tag (e.g. <script>...</script>) from a variable containing raw HTML data. [END] */

/* Remove all instances of dangerous and pesky <script> tags from a variable containing raw user-input HTML data. [BEGIN] */

/* Prerequisites: 'removeAllInstancesOfTag(...)' */

if (!function_exists('removeAllScriptTags'))
    {
        function removeAllScriptTags($html)
            {

            };
    };

/* Remove all instances of dangerous and pesky <script> tags from a variable containing raw user-input HTML data. [END] */

And here is a test usage example:

$html = 'This is a JavaScript retention test.<br><br><span id="chk_frst_scrpt">Congratulations! The first \'script\' tag was successfully removed!</span><br><br><span id="chk_secd_scrpt">Congratulations! The second \'script\' tag was successfully removed!</span><script>document.getElementById("chk_frst_scrpt").innerHTML = "Oops! The first \'script\' tag was NOT removed!";</script><script>document.getElementById("chk_secd_scrpt").innerHTML = "Oops! The second \'script\' tag was NOT removed!";</script>';
echo removeAllScriptTags($html);

I hope my answer really helps someone. Enjoy!

I tried ultrasawblade's recipe as it seemed the most practical to me, and couldn't make it work. In the end i devised another way though, based as others in parameter substitution, this time with regex replacement:

[[ "${var//*([[:digit:]])}" ]]; && echo "$var is not numeric" || echo "$var is numeric"

It removes every :digit: class character in $var and checks if we are left with an empty string, meaning that the original was only numbers.

What i like about this one is its small footprint and flexibility. In this form it only works for non-delimited, base 10 integers, though surely you can use pattern matching to suit it to other needs.

Did you install Git correctly?

According to the Bower site, you need to make sure you check the option "Run Git from Windows Command Prompt".

I had this issue where Git was not found when I was trying to install Angular. I re-ran the installer for git and changed my setting and then it worked.

The following seems to work as well, and it's a little bit shorter than the other answers:

T result = (T)Convert.ChangeType(otherTypeObject, typeof(T));

Swift

Short answer

Use a NotificationCenter observer rather than viewWillAppear.

override func viewDidLoad() {
    super.viewDidLoad()

    // set observer for UIApplication.willEnterForegroundNotification
    NotificationCenter.default.addObserver(self, selector: #selector(willEnterForeground), name: UIApplication.willEnterForegroundNotification, object: nil)

}

// my selector that was defined above
@objc func willEnterForeground() {
    // do stuff
}

Long answer

To find out when an app comes back from the background, use a NotificationCenter observer rather than viewWillAppear. Here is a sample project that shows which events happen when. (This is an adaptation of this Objective-C answer.)

import UIKit
class ViewController: UIViewController {

    // MARK: - Overrides

    override func viewDidLoad() {
        super.viewDidLoad()
        print("view did load")

        // add notification observers
        NotificationCenter.default.addObserver(self, selector: #selector(didBecomeActive), name: UIApplication.didBecomeActiveNotification, object: nil)
        NotificationCenter.default.addObserver(self, selector: #selector(willEnterForeground), name: UIApplication.willEnterForegroundNotification, object: nil)

    }

    override func viewWillAppear(_ animated: Bool) {
        print("view will appear")
    }

    override func viewDidAppear(_ animated: Bool) {
        print("view did appear")
    }

    // MARK: - Notification oberserver methods

    @objc func didBecomeActive() {
        print("did become active")
    }

    @objc func willEnterForeground() {
        print("will enter foreground")
    }

}

On first starting the app, the output order is:

view did load
view will appear
did become active
view did appear

After pushing the home button and then bringing the app back to the foreground, the output order is:

will enter foreground
did become active 

So if you were originally trying to use viewWillAppear then UIApplication.willEnterForegroundNotification is probably what you want.

Note

As of iOS 9 and later, you don't need to remove the observer. The documentation states:

If your app targets iOS 9.0 and later or macOS 10.11 and later, you don't need to unregister an observer in its dealloc method.

Starting from the base that the received value is a number and not a string, what about use Math.abs()? This JavaScript native function returns the absolute value of a number:

Math.abs(-1) // 1

So you can use it this way:

var a = -1;
if(a == Math.abs(a)){
    // false 
}

var b = 1;   
if(b == Math.abs(b)){
    // true
}

The original question was:

What is the fastest way to know if a value exists in a list (a list with millions of values in it) and what its index is?

Thus there are two things to find:

1. is an item in the list, and
2. what is the index (if in the list).

Towards this, I modified @xslittlegrass code to compute indexes in all cases, and added an additional method.

Results

Methods are:

1. in--basically if x in b: return b.index(x)
2. try--try/catch on b.index(x) (skips having to check if x in b)
3. set--basically if x in set(b): return b.index(x)
4. bisect--sort b with its index, binary search for x in sorted(b). Note mod from @xslittlegrass who returns the index in the sorted b, rather than the original b)
5. reverse--form a reverse lookup dictionary d for b; then d[x] provides the index of x.

Results show that method 5 is the fastest.

Interestingly the try and the set methods are equivalent in time.

(INNER) JOIN: Returns records that have matching values in both tables.

LEFT (OUTER) JOIN: Return all records from the left table, and the matched records from the right table.

RIGHT (OUTER) JOIN: Return all records from the right table, and the matched records from the left table.

FULL (OUTER) JOIN: Return all records when there is a match in either left or right table

For example, lets suppose we have two table with following records:

Table A

id   firstname   lastname
___________________________
1     Ram         Thapa
2     sam         Koirala
3     abc         xyz
6    sruthy       abc

Table B

id2   place
_____________
1      Nepal
2      USA
3      Lumbini
5      Kathmandu

Inner Join

Note: It give the intersection of two table.

Syntax

SELECT column_name FROM table1 INNER JOIN table2 ON table1.column_name = table2.column_name;

Apply it in your sample table:

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

Result will be:

firstName       lastName       Place
_____________________________________
  Ram         Thapa             Nepal
  sam         Koirala            USA
  abc         xyz              Lumbini

Left Join

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

SELECT column_name(s) FROM table1 LEFT JOIN table2 ON table1.column_name = table2.column_name;

Apply it in your sample table

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

Result will be:

firstName   lastName    Place
______________________________
 Ram         Thapa      Nepal
 sam         Koirala    USA
 abc         xyz        Lumbini
sruthy       abc        Null

Right Join

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

Syntax:

SELECT column_name(s) FROM table1 RIGHT JOIN table2 ON table1.column_name = table2.column_name;

Apply it in your samole table:

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

Result will bw:

firstName   lastName     Place
______________________________
Ram         Thapa         Nepal
sam         Koirala       USA
abc         xyz           Lumbini
Null        Null          Kathmandu

Full Join

Note : It is same as union operation, it will return all selected values from both tables.

Syntax:

SELECT column_name(s) FROM table1 FULL OUTER JOIN table2 ON table1.column_name = table2.column_name;

Apply it in your samp[le table:

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

Result will be:

firstName   lastName    Place
______________________________
 Ram         Thapa      Nepal
 sam         Koirala    USA
 abc         xyz        Lumbini
sruthy       abc        Null
 Null         Null      Kathmandu

Some facts

For INNER joins the order doesn't matter

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

Why use the rewrite module if you can do return? Technically speaking, return is part of the rewrite module as you can read here but this snippet is easier to read imho.

server {
    server_name  .domain.com;

    return 302 $scheme://forwarded-domain.com;
}

You can also give it a 301 redirect.

I usually use getReference method when i do not need to access database state (I mean getter method). Just to change state (I mean setter method). As you should know, getReference returns a proxy object which uses a powerful feature called automatic dirty checking. Suppose the following

public class Person {

    private String name;
    private Integer age;

}


public class PersonServiceImpl implements PersonService {

    public void changeAge(Integer personId, Integer newAge) {
        Person person = em.getReference(Person.class, personId);

        // person is a proxy
        person.setAge(newAge);
    }

}

If i call find method, JPA provider, behind the scenes, will call

SELECT NAME, AGE FROM PERSON WHERE PERSON_ID = ?

UPDATE PERSON SET AGE = ? WHERE PERSON_ID = ?

If i call getReference method, JPA provider, behind the scenes, will call

UPDATE PERSON SET AGE = ? WHERE PERSON_ID = ?

And you know why ???

When you call getReference, you will get a proxy object. Something like this one (JPA provider takes care of implementing this proxy)

public class PersonProxy {

    // JPA provider sets up this field when you call getReference
    private Integer personId;

    private String query = "UPDATE PERSON SET ";

    private boolean stateChanged = false;

    public void setAge(Integer newAge) {
        stateChanged = true;

        query += query + "AGE = " + newAge;
    }

}

So before transaction commit, JPA provider will see stateChanged flag in order to update OR NOT person entity. If no rows is updated after update statement, JPA provider will throw EntityNotFoundException according to JPA specification.

You want to use:

git checkout --ours foo/bar.java
git add foo/bar.java

If you rebase a branch feature_x against main (i.e. running git rebase main while on branch feature_x), during rebasing ours refers to main and theirs to feature_x.

As pointed out in the git-rebase docs:

Note that a rebase merge works by replaying each commit from the working branch on top of the branch. Because of this, when a merge conflict happens, the side reported as ours is the so-far rebased series, starting with <upstream>, and theirs is the working branch. In other words, the sides are swapped.

For further details read this thread.

In your asp.net app use this

using System.Configuration;
Response.Write(ConfigurationManager.OpenMachineConfiguration().FilePath);

Here is a way to write data from a dataframe into an excel file by different IDs and into different tabs (sheets) by another ID associated to the first level id. Imagine you have a dataframe that has email_address as one column for a number of different users, but each email has a number of 'sub-ids' that have all the data.

data <- tibble(id = c(1,2,3,4,5,6,7,8,9), email_address = c(rep('[email protected]',3), rep('[email protected]', 3), rep('[email protected]', 3)))

So ids 1,2,3 would be associated with [email protected]. The following code splits the data by email and then puts 1,2,3 into different tabs. The important thing is to set append = True when writing the .xlsx file.

temp_dir <- tempdir()

for(i in unique(data$email_address)){
    
  data %>% 
    filter(email_address == i) %>% 
    arrange(id) -> subset_data
  
  for(j in unique(subset_data$id)){
    write.xlsx(subset_data %>% filter(id == j), 
      file = str_c(temp_dir,"/your_filename_", str_extract(i, pattern = "\\b[A-Za-z0- 
       9._%+-]+"),'_', Sys.Date(), '.xlsx'), 
      sheetName = as.character(j), 
      append = TRUE)}
 
  }

The regex gets the name from the email address and puts it into the file-name.

Hope somebody finds this useful. I'm sure there's more elegant ways of doing this but it works.

Btw, here is a way to then send these individual files to the various email addresses in the data.frame. Code goes into second loop [j]

  send.mail(from = "[email protected]",
            to = i,
          subject = paste("Your report for", str_extract(i, pattern = "\\b[A-Za-z0-9._%+-]+"), 'on', Sys.Date()),
          body = "Your email body",
          authenticate = TRUE,
          smtp = list(host.name = "XXX", port = XXX,
                      user.name = Sys.getenv("XXX"), passwd = Sys.getenv("XXX")),
          attach.files = str_c(temp_dir, "/your_filename_", str_extract(i, pattern = "\\b[A-Za-z0-9._%+-]+"),'_', Sys.Date(), '.xlsx'))

If you want to use straight PowerShell check out the below code.

$content = Get-Content C:\Users\You\Documents\test.txt
foreach ($line in $content)
{
    Write-Host $line
}

$('#myForm').bind('submit', function () {
  var elements = this.elements;
});

The elements variable will contain all the inputs, selects, textareas and fieldsets within the form.

As of spring boot 2 the server.contextPath property is deprecated. Instead you should use server.servlet.contextPath.

So in your application.properties file add:

server.servlet.contextPath=/myWebApp

For more details see: https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-2.0-Migration-Guide#servlet-specific-server-properties

I suggest:

=not(isblank(A1))  

which returns TRUE if A1 is populated and FALSE otherwise. Which compares with:

=isblank(A1)  

which returns TRUE if A1 is empty and otherwise FALSE.

I just got this error and it turns out my AD administrator deleted the service account used by EVERY SQL Server instance in the entire company. Thank goodness AD has its own recycle bin.

See if you can run the Active Directory Users and Computers utility (%SystemRoot%\system32\dsa.msc), and check to make sure the account you are relying on still exists.

Url::current([], true);

or

Url::current();

We need to use Angular Js built in function $apply to acsess scope variables or functions outside the controller function.

This can be done in two ways :

|*| Method 1 : Using Id :

<div id="nameNgsDivUid" ng-app="">
    <a onclick="actNgsFnc()"> Activate Angular Scope</a><br><br>
    {{ nameNgsVar }}
</div>

<script type="text/javascript">

    var nameNgsDivVar = document.getElementById('nameNgsDivUid')

    function actNgsFnc()
    {
        var scopeNgsVar = angular.element(nameNgsDivVar).scope();
        scopeNgsVar.$apply(function()
        {
            scopeNgsVar.nameNgsVar = "Tst Txt";
        })
    }

</script>

|*| Method 2 : Using init of ng-controller :

<div ng-app="nameNgsApp" ng-controller="nameNgsCtl">
    <a onclick="actNgsFnc()"> Activate Angular Scope</a><br><br>
    {{ nameNgsVar }}
</div>

<script type="text/javascript">

    var scopeNgsVar;
    var nameNgsAppVar=angular.module("nameNgsApp",[])
    nameNgsAppVar.controller("nameNgsCtl",function($scope)
    {
        scopeNgsVar=$scope;
    })

    function actNgsFnc()
    {
        scopeNgsVar.$apply(function()
        {
            scopeNgsVar.nameNgsVar = "Tst Txt";
        })
    }

</script>

No, you cannot. But you can create a user defined table function.

In my case got a working solution through Cross-document Messaging (XDM) and Executing Chrome extension onclick instead of page load.

  chrome.tabs.query({active: true, currentWindow: true}, function (tabs) {
    var activeTab = tabs[0];
    chrome.tabs.sendMessage(activeTab.id, {"message": "clicked_browser_action"});
  });
});

myscript.js

chrome.runtime.onMessage.addListener(
    function (request, sender, sendResponse) {
        if (request.message === "clicked_browser_action") {
        console.log('Hello world!')
        }
    }
);

All of

std::string s(1, c); std::cout << s << std::endl;

and

std::cout << std::string(1, c) << std::endl;

and

std::string s; s.push_back(c); std::cout << s << std::endl;

worked for me.

Xcode Workspace vs Project

1. What is the difference between the two of them?

Workspace is a set of projects

2. What are they responsible for?

Workspace is responsible for dependencies between projects. Project is responsible for the source code.

3. Which one of them should I work with when I'm developing my Apps in team/alone?

You choice should depends on a type of your project. For example if your project relies on CocoaPods dependency manager it creates a workspace.

4. Is there anything else I should be aware of in matter of these two files?

A competitor of workspace is cross-project references^[About]

Use £. I had the same problem and solved it using jQuery:

$(this).text('£');

• If you try this and it does not work, just change the jQuery methods,

$(this).html('£');

• This always work in all contexts...

Try to remove the space when using the -p-option. This works for my OSX and Linux mysqldump:

mysqldump -u user -ppassword ...

In my case problem was in css and html layout. Layout was something like html - body - root - ... html and body was overflow: hidden, and root was position: fixed, height: 100vh.

Whith this layout browser tabs on mobile doesnt hide. For solve this I delete overflow: hidden from html and body and delete position: fixed, height: 100vh from root.

You can create a trigger which updates NoofUses column in Coupon table whenever couponid is used in CouponUse table

query :

CREATE TRIGGER [dbo].[couponcount] ON [dbo].[couponuse]
FOR INSERT
AS
if EXISTS (SELECT 1 FROM Inserted)
  BEGIN
UPDATE dbo.Coupon
SET NoofUses = (SELECT COUNT(*) FROM dbo.CouponUse WHERE Couponid = dbo.Coupon.ID)
end

Remove the \bin, and also remove the ; at the end. After restart the cmd and run.

If you are prepending an array to the front of another array, it is more efficient to just use concat. So:

var newArray = values.concat(oldArray);

But this will still be O(N) in the size of oldArray. Still, it is more efficient than manually iterating over oldArray. Also, depending on the details, it may help you, because if you are going to prepend many values, it's better to put them into an array first and then concat oldArray on the end, rather than prepending each one individually.

There's no way to do better than O(N) in the size of oldArray, because arrays are stored in contiguous memory with the first element in a fixed position. If you want to insert before the first element, you need to move all the other elements. If you need a way around this, do what @GWW said and use a linked list, or a different data structure.

If you have set the environment variables (JAVA_HOME and PATH) under user variables, command prompt (run as administrator) will not identify java. For that you need to set environment variables under system variables.

If you know you're going to have a limited number of max options then I would try this (example for max of 4 options per order):

Select OI.ID, OI.Item_Name, OO1.Value, OO2.Value, OO3.Value, OO4.Value

FROM Ordered_Items OI
    LEFT JOIN Ordered_Options OO1 ON OO1.Ordered_Item_ID = OI.ID
    LEFT JOIN Ordered_Options OO2 ON OO2.Ordered_Item_ID = OI.ID AND OO2.ID != OO1.ID
    LEFT JOIN Ordered_Options OO3 ON OO3.Ordered_Item_ID = OI.ID AND OO3.ID != OO1.ID AND OO3.ID != OO2.ID
    LEFT JOIN Ordered_Options OO4 ON OO4.Ordered_Item_ID = OI.ID AND OO4.ID != OO1.ID AND OO4.ID != OO2.ID AND OO4.ID != OO3.ID

GROUP BY OI.ID, OI.Item_Name

The group by condition gets rid of all of the duplicates that you would otherwise get. I've just implemented something similar on a site I'm working on where I knew I'd always have 1 or 2 matched in my child table, and I wanted to make sure I only had 1 row for each parent item.

This construction is not allowed in SQL Server. An inline table-valued function can perform as a parameterized view, but is still not allowed to call an SP like this.

Here's some examples of using an SP and an inline TVF interchangeably - you'll see that the TVF is more flexible (it's basically more like a view than a function), so where an inline TVF can be used, they can be more re-eusable:

If you have an access to that domain/iframe that is loaded, then you can use window.postMessage to communicate between iframe and the main window.

Read the DOM with JavaScript in iframe and send it via postMessage to the top window.

I posted this already at some other websites and though why not share it with guys/gals at stackoverflow.

1. Install the Video DownloadHelper extension on Firefox browser.
2. With DownloadHelper activated, navigate to the webpage containing the video that you want to download.
3. Once the video is streaming, click on the DownloadHelper icon. It will give you a list of all file formats available on the current video.
4. Scroll onto the file format that you wish to download
5. On the right hand side, you will see an arrow
6. Click on that arrow to get more information regarding the current video and the selected format
7. From the displayed window at the end of that arrow, scroll down and select "Details"
8. You now have all the details concerning the current video and the selected format. It is something like this.

Hit Details? _needsAggregate _needsCoapp actions bitrate chunked descrPrefix durationFloat extension frameId fromCache group
hls id isPrivate length masterManifest mediaManifest originalId referrer size status title topUrl url urlFilename

9. Now, look at the specifics of the referrer in that Hit Details. That's the url you want. Copy it and paste on your favorite downloader.

You can use array_sum().

$total = array_sum($group);

Had the same issue, my app is behind nginx. Making these changes to my Nginx config removed the error.

location / {
proxy_pass http://localhost:8080;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_set_header Host $host;
}

I run into this when click on a html , it is fixed by adding type = "button" attribute.

The fcntl module is just used for locking the pinning file, so assuming you don't try multiple access, this can be an acceptable workaround. Place this module in your sys.path, and it should just work as the official fcntl module.

Try using this module for development/testing purposes only in windows.

def fcntl(fd, op, arg=0):
    return 0

def ioctl(fd, op, arg=0, mutable_flag=True):
    if mutable_flag:
        return 0
    else:
        return ""

def flock(fd, op):
    return

def lockf(fd, operation, length=0, start=0, whence=0):
    return

If the command sha256sum is not available (on Mac OS X v10.9 (Mavericks) for example), you can use:

echo -n "foobar" | shasum -a 256

Use either a simple blank * or [:blank:]* to remove all possible spaces at the end of the line:

sed 's/ *$//' file

Using the [:blank:] class you are removing spaces and tabs:

sed 's/[[:blank:]]*$//' file

Note this is POSIX, hence compatible in both GNU sed and BSD.

For just GNU sed you can use the GNU extension \s* to match spaces and tabs, as described in BaBL86's answer. See POSIX specifications on Basic Regular Expressions.

Let's test it with a simple file consisting on just lines, two with just spaces and the last one also with tabs:

$ cat -vet file
hello   $
bye   $
ha^I  $     # there is a tab here

Remove just spaces:

$ sed 's/ *$//' file | cat -vet -
hello$
bye$
ha^I$       # tab is still here!

Remove spaces and tabs:

$ sed 's/[[:blank:]]*$//' file | cat -vet -
hello$
bye$
ha$         # tab was removed!

Change your method from

public void updateReceiptsList(List<Receipt> newlist) {
    receiptlist = newlist;
    this.notifyDataSetChanged();
}

To

public void updateReceiptsList(List<Receipt> newlist) {
    receiptlist.clear();
    receiptlist.addAll(newlist);
    this.notifyDataSetChanged();
}

So you keep the same object as your DataSet in your Adapter.

With Android O the behaviour of the ANDROID_ID will change. The ANDROID_ID will be different per app per user on the phone.

Taken from: https://android-developers.googleblog.com/2017/04/changes-to-device-identifiers-in.html

Android ID

In O, Android ID (Settings.Secure.ANDROID_ID or SSAID) has a different value for each app and each user on the device. Developers requiring a device-scoped identifier, should instead use a resettable identifier, such as Advertising ID, giving users more control. Advertising ID also provides a user-facing setting to limit ad tracking.

Additionally in Android O:

• The ANDROID_ID value won't change on package uninstall/reinstall, as long as the package name and signing key are the same. Apps can rely on this value to maintain state across reinstalls.
• If an app was installed on a device running an earlier version of Android, the Android ID remains the same when the device is updated to Android O, unless the app is uninstalled and reinstalled.
• The Android ID value only changes if the device is factory reset or if the signing key rotates between uninstall and
  reinstall events.
• This change is only required for device manufacturers shipping with Google Play services and Advertising ID. Other device manufacturers may provide an alternative resettable ID or continue to provide ANDROID ID.

Idiomatic Matlab plot(x1,y1,x2,y2) can be translated in R with ggplot2 for example in this way:

x1 <- seq(1,10,.2)
df1 <- data.frame(x=x1,y=log(x1),type="Log")
x2 <- seq(1,10)
df2 <- data.frame(x=x2,y=cumsum(1/x2),type="Harmonic")

df <- rbind(df1,df2)

library(ggplot2)
ggplot(df)+geom_line(aes(x,y,colour=type))

^{Inspired by Tingting Zhao's Dual line plots with different range of x-axis Using ggplot2.}

It is possible to use a handler to do this, even in MVC4. Here's an example from one i made earlier:

public class ImageHandler : IHttpHandler
{
    byte[] bytes;

    public void ProcessRequest(HttpContext context)
    {
        int param;
        if (int.TryParse(context.Request.QueryString["id"], out param))
        {
            using (var db = new MusicLibContext())
            {
                if (param == -1)
                {
                    bytes = File.ReadAllBytes(HttpContext.Current.Server.MapPath("~/Images/add.png"));

                    context.Response.ContentType = "image/png";
                }
                else
                {
                    var data = (from x in db.Images
                                where x.ImageID == (short)param
                                select x).FirstOrDefault();

                    bytes = data.ImageData;

                    context.Response.ContentType = "image/" + data.ImageFileType;
                }

                context.Response.Cache.SetCacheability(HttpCacheability.NoCache);
                context.Response.BinaryWrite(bytes);
                context.Response.Flush();
                context.Response.End();
            }
        }
        else
        {
            //image not found
        }
    }

    public bool IsReusable
    {
        get
        {
            return false;
        }
    }
}

In the view, i added the ID of the photo to the query string of the handler.

What about display:inline?

<html>
      <img src='#' style='display:inline;'/>
      <p style='display:inline;'> Some text </p>
</html>

He who is Shy^* gave you the germ of an answer, but only the germ. The basic technique for converting a value into a string in the C pre-processor is indeed via the '#' operator, but a simple transliteration of the proposed solution gets a compilation error:

#define TEST_FUNC test_func
#define TEST_FUNC_NAME #TEST_FUNC

#include <stdio.h>
int main(void)
{
    puts(TEST_FUNC_NAME);
    return(0);
}

The syntax error is on the 'puts()' line - the problem is a 'stray #' in the source.

In section 6.10.3.2 of the C standard, 'The # operator', it says:

Each # preprocessing token in the replacement list for a function-like macro shall be followed by a parameter as the next preprocessing token in the replacement list.

The trouble is that you can convert macro arguments to strings -- but you can't convert random items that are not macro arguments.

So, to achieve the effect you are after, you most certainly have to do some extra work.

#define FUNCTION_NAME(name) #name
#define TEST_FUNC_NAME  FUNCTION_NAME(test_func)

#include <stdio.h>

int main(void)
{
    puts(TEST_FUNC_NAME);
    return(0);
}

I'm not completely clear on how you plan to use the macros, and how you plan to avoid repetition altogether. This slightly more elaborate example might be more informative. The use of a macro equivalent to STR_VALUE is an idiom that is necessary to get the desired result.

#define STR_VALUE(arg)      #arg
#define FUNCTION_NAME(name) STR_VALUE(name)

#define TEST_FUNC      test_func
#define TEST_FUNC_NAME FUNCTION_NAME(TEST_FUNC)

#include <stdio.h>

static void TEST_FUNC(void)
{
    printf("In function %s\n", TEST_FUNC_NAME);
}

int main(void)
{
    puts(TEST_FUNC_NAME);
    TEST_FUNC();
    return(0);
}

sum(l) / float(len(l)) is the right answer, but just for completeness you can compute an average with a single reduce:

>>> reduce(lambda x, y: x + y / float(len(l)), l, 0)
20.111111111111114

Note that this can result in a slight rounding error:

>>> sum(l) / float(len(l))
20.111111111111111

$ is short-hand for String.Format and is used with string interpolations, which is a new feature of C# 6. As used in your case, it does nothing, just as string.Format() would do nothing.

It is comes into its own when used to build strings with reference to other values. What previously had to be written as:

var anInt = 1;
var aBool = true;
var aString = "3";
var formated = string.Format("{0},{1},{2}", anInt, aBool, aString);

Now becomes:

var anInt = 1;
var aBool = true;
var aString = "3";
var formated = $"{anInt},{aBool},{aString}";

There's also an alternative - less well known - form of string interpolation using $@ (the order of the two symbols is important). It allows the features of a @"" string to be mixed with $"" to support string interpolations without the need for \\ throughout your string. So the following two lines:

var someDir = "a";
Console.WriteLine($@"c:\{someDir}\b\c");

will output:

c:\a\b\c

Does not work, you have to do this:

if ( $("#your_select_id option[value='enter_value_here']").length == 0 ){
  alert("option doesn't exist!");
}

Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.youtube.com/watchv=cxLG2wtE7TM"));
startActivity(intent);

I'll try a standard "Why are you doing it this way?" answer... Do you know about java.net.URL?

URL url = new URL(stringURL);

The above will throw a MalformedURLException if it can't parse the URL.

Add a tabIndex attribute to the body:

If you want your container ports to bind on your ipv4 address, just :

• find the settings file
  • /etc/sysconfig/docker-network on RedHat alike
  • /etc/default/docker-network on Debian ans alike
• edit the network settings
  • add DOCKER_NETWORK_OPTIONS=-ip=xx.xx.xx.xx
  • xx.xx.xx.xx being your real ipv4 (and not 0.0.0.0)
• restart docker deamon

works for me on docker 1.9.1

a) Can you explain to me the difference between int64_t and long (long int)? In my understanding, both are 64 bit integers. Is there any reason to choose one over the other?

The former is a signed integer type with exactly 64 bits. The latter is a signed integer type with at least 32 bits.

b) I tried to look up the definition of int64_t on the web, without much success. Is there an authoritative source I need to consult for such questions?

http://cppreference.com covers this here: http://en.cppreference.com/w/cpp/types/integer. The authoritative source, however, is the C++ standard (this particular bit can be found in §18.4 Integer types [cstdint]).

c) For code using int64_t to compile, I am including <iostream>, which doesn't make much sense to me. Are there other includes that provide a declaration of int64_t?

It is declared in <cstdint> or <cinttypes> (under namespace std), or in <stdint.h> or <inttypes.h> (in the global namespace).

I guess something like this would work:

Add System.ServiceProcess to your project references (It's on the .NET tab).

using System.ServiceProcess;

ServiceController sc = new ServiceController(SERVICENAME);

switch (sc.Status)
{
    case ServiceControllerStatus.Running:
        return "Running";
    case ServiceControllerStatus.Stopped:
        return "Stopped";
    case ServiceControllerStatus.Paused:
        return "Paused";
    case ServiceControllerStatus.StopPending:
        return "Stopping";
    case ServiceControllerStatus.StartPending:
        return "Starting";
    default:
        return "Status Changing";
}

Edit: There is also a method sc.WaitforStatus() that takes a desired status and a timeout, never used it but it may suit your needs.

Edit: Once you get the status, to get the status again you will need to call sc.Refresh() first.

Reference: ServiceController object in .NET.

Ajax.BeginForm looks to be a fail.

Using a regular Html.Begin for, this does the trick just nicely:

$('#detailsform').submit(function(e) {
    e.preventDefault();
    $.post($(this).attr("action"), $(this).serialize(), function(r) {
        $("#edit").html(r);
    });
});

If you are using VB as code behind, you have to use bracket "()" instead of square bracket "[]".

Example for VB:

<script type="text/javascript">
var accesslevel = '<%= Session("accesslevel").ToString().ToLower() %>';
</script>  

In addition to @chanafdo answer, you can use route name

when working with laravel blade

<a href="{{route('login')}}">login here</a> with parameter in route name

when go to url like URI: profile/{id} <a href="{{route('profile', ['id' => 1])}}">login here</a>

without blade

<a href="<?php echo route('login')?>">login here</a>

with parameter in route name

when go to url like URI: profile/{id} <a href="<?php echo route('profile', ['id' => 1])?>">login here</a>

As of laravel 5.2 you can use @php @endphp to create as <?php ?> in laravel blade. Using blade your personal opinion but I suggest to use it. Learn it. It has many wonderful features as template inheritance, Components & Slots,subviews etc...

ALTER SCHEMA TargetSchema 
    TRANSFER SourceSchema.TableName;

<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=2, user-scalable=yes">

Your convention seems to be reasonable. If I were searching for your framework in the Maven repo, I would look for awesome-inhouse-framework-x.y.jar in com.mycompany.awesomeinhouseframework group directory. And I would find it there according to your convention.

Two simple rules work for me:

• reverse-domain-packages for groupId (since such are quite unique) with all the constrains regarding Java packages names
• project name as artifactId (keeping in mind that it should be jar-name friendly i.e. not contain characters that maybe invalid for a file name or just look weird)

I solved the problem adding a slash at the end of the requesting url

This way: '/data/180/' instead of: '/data/180'

Use the View for your efforts in altering the position of the column: CREATE VIEW CORRECTED_POSITION AS SELECT co1_1, col_3, col_2 FROM UNORDERDED_POSITION should help.

This requests are made so some reports get produced where it is using SELECT * FROM [table_name]. Or, some business has a hierarchy approach of placing the information in order for better readability from the back end.

I have created my own iterator to iterate over Outlook objects via python. The issue is that python tries to iterates starting with Index[0], but outlook expects for first item Index[1]... To make it more Ruby simple, there is below a helper class Oli with following methods:

.items() - yields a tuple(index, Item)...

.prop() - helping to introspect outlook object exposing available properties (methods and attributes)

from win32com.client import constants
from win32com.client.gencache import EnsureDispatch as Dispatch

outlook = Dispatch("Outlook.Application")
mapi = outlook.GetNamespace("MAPI")

class Oli():
    def __init__(self, outlook_object):
        self._obj = outlook_object

    def items(self):
        array_size = self._obj.Count
        for item_index in xrange(1,array_size+1):
            yield (item_index, self._obj[item_index])

    def prop(self):
        return sorted( self._obj._prop_map_get_.keys() )

for inx, folder in Oli(mapi.Folders).items():
    # iterate all Outlook folders (top level)
    print "-"*70
    print folder.Name

    for inx,subfolder in Oli(folder.Folders).items():
        print "(%i)" % inx, subfolder.Name,"=> ", subfolder

Just coerce the StatusCode to int.

var statusNumber;
try {
   response = (HttpWebResponse)request.GetResponse();
   // This will have statii from 200 to 30x
   statusNumber = (int)response.StatusCode;
}
catch (WebException we) {
    // Statii 400 to 50x will be here
    statusNumber = (int)we.Response.StatusCode;
}

The simplest and shortest way I could find for SQL Server 2012 and above is BINARY BASE64 :

SELECT CAST('string' as varbinary(max)) FOR XML PATH(''), BINARY BASE64

For Base64 to string

SELECT CAST( CAST( 'c3RyaW5n' as XML ).value('.','varbinary(max)') AS varchar(max) )

( or nvarchar(max) for Unicode strings )

you can use this too

.parent:hover * {
   /* ... */
}

Apparently YouTube constantly polls for Google Cast scripts even if the extension isn't installed.

From one commenter:

... it appears that Chrome attempts to get cast_sender.js on pages that have YouTube content. I'm guessing when Chrome sees media that it can stream it attempts to access the Chromecast extension. When the extension isn't present, the error is thrown.

The only solution I've come across is to install the Google Cast extension, whether you need it or not. You may then hide the toolbar button.

In case than you want to store a complex command to compare text result, for example to compare the version of OS, maybe this can help you:

tasks:
       - shell: echo $(cat /etc/issue | awk {'print $7'})
         register: echo_content

       - shell: echo "It works"
         when: echo_content.stdout == "12"
         register: out
       - debug: var=out.stdout_lines

You have two choices: stash your changes:

git stash

then later to get them back:

git stash apply

or put your changes on a branch so you can get the remote branch and then merge your changes onto it. That's one of the greatest things about git: you can make a branch, commit to it, then fetch other changes on to the branch you were on.

You say it doesn't make any sense, but you are only doing it so you can merge them at will after doing the pull. Obviously your other choice is to commit on your copy of the branch and then do the pull. The presumption is you either don't want to do that (in which case I am puzzled that you don't want a branch) or you are afraid of conflicts.

You could use Series.reindex:

import pandas as pd

idx = pd.date_range('09-01-2013', '09-30-2013')

s = pd.Series({'09-02-2013': 2,
               '09-03-2013': 10,
               '09-06-2013': 5,
               '09-07-2013': 1})
s.index = pd.DatetimeIndex(s.index)

s = s.reindex(idx, fill_value=0)
print(s)

yields

2013-09-01     0
2013-09-02     2
2013-09-03    10
2013-09-04     0
2013-09-05     0
2013-09-06     5
2013-09-07     1
2013-09-08     0
...

If someone uses jquery, he can do it like this :

var click_count = 0;
$( "canvas" ).bind( "click", function( event ) {
    //do whatever you want
    click_count++;
    if ( click_count == 50 ) {
        //remove the event
        $( this ).unbind( event );
    }
});

Hope that it can help someone. Note that the answer given by @user113716 work nicely :)

From my understanding of your question, you are using a BackgroundWorker as a standard Thread.

The reason why BackgroundWorker is recommended for things that you don't want to tie up the UI thread is because it exposes some nice events when doing Win Forms development.

Events like RunWorkerCompleted to signal when the thread has completed what it needed to do, and the ProgressChanged event to update the GUI on the threads progress.

So if you aren't making use of these, I don't see any harm in using a standard Thread for what you need to do.

You can use:

\\

That's ok, for example:

if (invName.substring(j,k).equals("\\")) {
    copyf=invName.substring(0,j);
}

As I understand it, the selected answer still loads all of the related tests. According to this msdn blog, there is a better way.

http://blogs.msdn.com/b/adonet/archive/2011/01/31/using-dbcontext-in-ef-feature-ctp5-part-6-loading-related-entities.aspx

Specifically

using (var context = new UnicornsContext())

    var princess = context.Princesses.Find(1);

    // Count how many unicorns the princess owns 
    var unicornHaul = context.Entry(princess)
                      .Collection(p => p.Unicorns)
                      .Query()
                      .Count();
}

@Query("SELECT rd FROM ReleaseDateType rd, CacheMedia cm WHERE ...")

The problem you're running into is that you're trying to replace an entire row object. That is not allowed by the DataTable API. Instead you have to update the values in the columns of a row object. Or add a new row to the collection.

To update the column of a particular row you can access it by name or index. For instance you could write the following code to update the column "Foo" to be the value strVerse

dtResult.Rows(i)("Foo") = strVerse

Of course user351809, stringname.equalsignorecase(null) will throw NullPointerException.
See, you have a string object stringname, which follows 2 possible conditions:-

1. stringname has a some non-null string value (say "computer"):
   Your code will work fine as it takes the form
   "computer".equalsignorecase(null)
   and you get the expected response as false.
2. stringname has a null value:
   Here your code will get stuck, as
   null.equalsignorecase(null)
   However, seems good at first look and you may hope response as true,
   but, null is not an object that can execute the equalsignorecase() method.

Hence, you get the exception due to case 2.
What I suggest you is to simply use stringname == null

I did the following

1. Delete my db.sqlite3 database
2. python manage.py makemigrations
3. python manage.py migrate

It renewed the database and fixed the issues without affecting my project. Please note you might need to do python manage.py createsuperuser because it will affect all your objects being created.

I was actually wondering how to do this today...and coincidentally, Phil Haack posted a tip about using posh-git (Git on powershell), which gives you tab auto-complete and a few more cool bits. I'm not going back to Git bash.

See the documentation for sys.path:

http://docs.python.org/library/sys.html#sys.path

To quote:

If the script directory is not available (e.g. if the interpreter is invoked interactively or if the script is read from standard input), path[0] is the empty string, which directs Python to search modules in the current directory first.

So, there's no need to monkey with sys.path if you're starting the python interpreter from the directory containing your module.

Also, to import your package, just do:

import mypackage

Since the directory containing the package is already in sys.path, it should work fine.

Another way is presented here

http://gilfster.blogspot.co.at/2006/03/debugging-stored-procedures-in-mysql.html

with custom debug mySql procedures and logging tables.

You can also just place a simple select in your code and see if it is executed.

SELECT 'Message Text' AS `Title`; 

I got this idea from

>>> s = pd.Series(d)

>>> s['bar']

I've just pushed my own framework, CATCH, out there. It's still under development but I believe it already surpasses most other frameworks. Different people have different criteria but I've tried to cover most ground without too many trade-offs. Take a look at my linked blog entry for a taster. My top five features are:

• Header only
• Auto registration of function and method based tests
• Decomposes standard C++ expressions into LHS and RHS (so you don't need a whole family of assert macros).
• Support for nested sections within a function based fixture
• Name tests using natural language - function/ method names are generated

It also has Objective-C bindings. The project is hosted on Github

The char is a fixed-length character data type, the varchar is a variable-length character data type.

Because char is a fixed-length data type, the storage size of the char value is equal to the maximum size for this column. Because varchar is a variable-length data type, the storage size of the varchar value is the actual length of the data entered, not the maximum size for this column.

You can use char when the data entries in a column are expected to be the same size. You can use varchar when the data entries in a column are expected to vary considerably in size.

Do not use Bitmap.Config.ARGB_8888

Instead use int w = WIDTH_PX, h = HEIGHT_PX;

Bitmap.Config conf = Bitmap.Config.ARGB_4444; // see other conf types
Bitmap bmp = Bitmap.createBitmap(w, h, conf); // this creates a MUTABLE bitmap
Canvas canvas = new Canvas(bmp);

// ready to draw on that bitmap through that canvas

ARGB_8888 can land you in OutOfMemory issues when dealing with more bitmaps or large bitmaps. Or better yet, try avoiding usage of ARGB option itself.

I'd like to suggest another way to maintain python session through tmux on linux. you run tmux, attach your self to the session you opened (if not attached after opening it directly). execute python and do whatever you are doing on it. then detach from session. detaching from a tmux session does not close the session. the session remains open.

pros of this method: you can attach to this session from any other device (in case you can ssh your pc)

cons of this method: this method does not relinquish the resources used by the opened python session until you actually exist the python interpreter.

result() returns Object type data. . . . result_array() returns Associative Array type data.

Well, in mathematics to convert a negative number to a positive number you just need to multiple the negative number by -1;

Then your solution could be like this:

a = a * -1;

or shorter:

a *= -1;

For Anonymous classes:

In response to question edits here is how it works for Anonymous classes

   final X parameter = ...; // the final is important
   Thread t = new Thread(new Runnable() {
       p = parameter;
       public void run() { 
         ...
       };
   t.start();

Named classes:

You have a class that extends Thread (or implements Runnable) and a constructor with the parameters you'd like to pass. Then, when you create the new thread, you have to pass in the arguments, and then start the thread, something like this:

Thread t = new MyThread(args...);
t.start();

Runnable is a much better solution than Thread BTW. So I'd prefer:

   public class MyRunnable implements Runnable {
      private X parameter;
      public MyRunnable(X parameter) {
         this.parameter = parameter;
      }

      public void run() {
      }
   }
   Thread t = new Thread(new MyRunnable(parameter));
   t.start();

This answer is basically the same as this similar question: How to pass parameters to a Thread object

During installation of your program, just prompt the user and have a DOS Batch script or a Bash shell script download and copy the JCE into the proper system location.

I used to have to do this for a server webservice and instead of a formal installer, I just provided scripts to setup the app before the user could run it. You can make the app un-runnable until they run the setup script. You could also make the app complain that the JCE is missing and then ask to download and restart the app?

certainly this is a better solution because it's easier to read and therefore less prone to errors. The only problem is, we need to add a few lines of code to avoid multiple selection of one element.

Another O(n^2) solution (by using a hashset).

// K is the sum that we are looking for
for i 1..n
    int s1 = K - A[i]
    for j 1..i
        int s2 = s1 - A[j]
        if (set.contains(s2))
            print the numbers
    set.add(A[i])

I have used a lexicographic order algorithm to get all possible permutations, but a recursive algorithm is more efficient. You can find the code for recursive algorithm here: Python recursion permutations

driver.findElement(By.id("invoice_supplier_id")).setAttribute("value", "your value");

DATEADD is the way to go with this

See the W3Schools tutorial: http://www.w3schools.com/sql/func_dateadd.asp

If you are using Spring Framework with application.yml and having trouble to make the test find the SQL file on the INIT property, you can use the classpath: notation.

For example, if you have a init.sql SQL file on the src/test/resources, just use:

url=jdbc:h2:~/test;INIT=RUNSCRIPT FROM 'classpath:init.sql';DB_CLOSE_DELAY=-1;

This would get you the index of the clicked row, starting with one:

$('#thetable').find('tr').click( function(){_x000D_
alert('You clicked row '+ ($(this).index()+1) );_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<table id="thetable">_x000D_
   <tr>_x000D_
      <td>1</td><td>1</td><td>1</td>_x000D_
   </tr>_x000D_
   <tr>_x000D_
      <td>2</td><td>2</td><td>2</td>_x000D_
   </tr>_x000D_
   <tr>_x000D_
      <td>3</td><td>3</td><td>3</td>_x000D_
   </tr>_x000D_
</table>

If you want to return the number stored in that first cell of each row:

$('#thetable').find('tr').click( function(){
  var row = $(this).find('td:first').text();
  alert('You clicked ' + row);
});
