According to the docs you can set the parse_mode field to:

• MarkdownV2
• HTML

Markdown still works but it's now considered a legacy mode.

You can pass the parse_mode parameter like this:

https://api.telegram.org/bot[yourBotKey]/sendMessage?chat_id=[yourChatId]&parse_mode=MarkdownV2&text=[yourMessage]

For bold and italic using MarkdownV2:

*bold text*
_italic text_

And for HTML:

<b>bold</b> or <strong>bold</strong>
<i>italic</I> or <em>italic</em>

Make sure to encode your query-string parameters regardless the format you pick. For example:

• Java/Scala (see note on spaces):

val message = "*bold text*";
val encodedMsg = URLEncoder.encode(message, "UTF-8");

• Javascript (ref)

var message = "*bold text*"
var encodedMsg = encodeURIComponent(message)

• PHP (ref)

$message = "*bold text*";
$encodedMsg = urlencode($message);

You are almost there. (note change in the return value of FindWindow declaration). I'd recommend using RegisterWindowMessage in this case so you don't have to worry about the ins and outs of WM_USER.

[DllImport("user32.dll")]    
public static extern IntPtr FindWindow(string lpClassName, String lpWindowName);    
[DllImport("user32.dll")]    
public static extern int SendMessage(IntPtr hWnd, int wMsg, IntPtr wParam, IntPtr lParam);    
[DllImport("user32.dll", SetLastError=true, CharSet=CharSet.Auto)]
static extern uint RegisterWindowMessage(string lpString);

public void button1_Click(object sender, EventArgs e)   
{        
     // this would likely go in a constructor because you only need to call it 
     // once per process to get the id - multiple calls in the same instance 
     // of a windows session return the same value for a given string
     uint id = RegisterWindowMessage("MyUniqueMessageIdentifier");
     IntPtr WindowToFind = FindWindow(null, "Form1");    
     Debug.Assert(WindowToFind != IntPtr.Zero);
     SendMessage(WindowToFind, id, IntPtr.Zero, IntPtr.Zero);
}

And then in your Form1 class:

class Form1 : Form
{
    [DllImport("user32.dll", SetLastError=true, CharSet=CharSet.Auto)]
    static extern uint RegisterWindowMessage(string lpString);

    private uint _messageId = RegisterWindowMessage("MyUniqueMessageIdentifier");

    protected override void WndProc(ref Message m)
    {
       if (m.Msg == _messageId)
       {
           // do stuff

       }
       base.WndProc(ref m);
    }
}

Bear in mind I haven't compiled any of the above so some tweaking may be necessary. Also bear in mind that other answers warning you away from SendMessage are spot on. It's not the preferred way of inter module communication nowadays and genrally speaking overriding the WndProc and using SendMessage/PostMessage implies a good understanding of how the Win32 message infrastructure works.

But if you want/need to go this route I think the above will get you going in the right direction.

What you want is the outer HTML, not the inner HTML :

$('<some element/>')[0].outerHTML;

I have always tested the number of open workbooks in Workbook_Open(). If it is 1, then the workbook was opened by the command line (or the user closed all the workbooks, then opened this one).

If Workbooks.Count = 1 Then

    ' execute the macro or call another procedure - I always do the latter  
    PublishReport

    ThisWorkbook.Save

    Application.Quit

End If

Yes for some reason WebView.reload() causes a crash if it failed to load before (something to do with the way it handles history). This is the code I use to refresh my webview. I store the current url in self.url

# 1: Pause timeout and page loading

self.timeout.pause()
sleep(1)

# 2: Check for internet connection (Really lazy way)

while self.page().networkAccessManager().networkAccessible() == QNetworkAccessManager.NotAccessible: sleep(2)

# 3:Try again

if self.url == self.page().mainFrame().url():
    self.page().action(QWebPage.Reload)
    self.timeout.resume(60)

else:
    self.page().action(QWebPage.Stop)
    self.page().mainFrame().load(self.url)
    self.timeout.resume(30)

return False

This might be helpful. I created firebase HTTP cloud function with express(custom URL)

const express = require('express');
const bodyParser = require('body-parser');
const cors = require("cors");
const app = express();
const main = express();

app.post('/endpoint', (req, res) => {
    // code here
})

app.use(cors({ origin: true }));
main.use(cors({ origin: true }));
main.use('/api/v1', app);
main.use(bodyParser.json());
main.use(bodyParser.urlencoded({ extended: false }));

module.exports.functionName = functions.https.onRequest(main);

Please make sure you added rewrite sections

"rewrites": [
      {
        "source": "/api/v1/**",
        "function": "functionName"
      }
]

So I assume your permissions table has a foreign key reference to admin_accounts table. If so because of referential integrity you will only be able to add permissions for account ids exsiting in the admin accounts table. Which also means that you wont be able to enter a user_account_id [assuming there are no duplicates!]

Try something like this

$state.go($state.$current.name, {... $state.params, 'key': newValue}, {notify: false})

To reset the keys of all arrays in an array:

$arr = array_map('array_values', $arr);

In case you just want to reset first-level array keys, use array_values() without array_map.

If you dont want any of your local branch changes i think this is the best approach

git clean -df
git reset --hard
git checkout REMOTE_BRANCH_NAME
git pull origin REMOTE_BRANCH_NAME

This is working in IE 11 with Bootstrap 4.3. While the other answers were not working in IE11 in my case.

By default, CORS does not include cookies on cross-origin requests. This is different from other cross-origin techniques such as JSON-P. JSON-P always includes cookies with the request, and this behavior can lead to a class of vulnerabilities called cross-site request forgery, or CSRF.

In order to reduce the chance of CSRF vulnerabilities in CORS, CORS requires both the server and the client to acknowledge that it is ok to include cookies on requests. Doing this makes cookies an active decision, rather than something that happens passively without any control.

The client code must set the withCredentials property on the XMLHttpRequest to true in order to give permission.

However, this header alone is not enough. The server must respond with the Access-Control-Allow-Credentials header. Responding with this header to true means that the server allows cookies (or other user credentials) to be included on cross-origin requests.

You also need to make sure your browser isn't blocking third-party cookies if you want cross-origin credentialed requests to work.

Note that regardless of whether you are making same-origin or cross-origin requests, you need to protect your site from CSRF (especially if your request includes cookies).

How just spotted here the problem is that you have to wait that the programs that you run from your script finish their jobs.
If in your script you run program in background you can try something more.

In general a call to sync before you exit allows to flush file system buffers and can help a little.

If in the script you start some programs in background (&), you can wait that they finish before you exit from the script. To have an idea about how it can function you can see below

#!/bin/bash
#... some stuffs ...
program_1 &          # here you start a program 1 in background
PID_PROGRAM_1=${!}   # here you remember its PID
#... some other stuffs ... 
program_2 &          # here you start a program 2 in background
wait ${!}            # You wait it finish not really useful here
#... some other stuffs ... 
daemon_1 &           # We will not wait it will finish
program_3 &          # here you start a program 1 in background
PID_PROGRAM_3=${!}   # here you remember its PID
#... last other stuffs ... 
sync
wait $PID_PROGRAM_1
wait $PID_PROGRAM_3  # program 2 is just ended
# ...

Since wait works with jobs as well as with PID numbers a lazy solution should be to put at the end of the script

for job in `jobs -p`
do
   wait $job 
done

More difficult is the situation if you run something that run something else in background because you have to search and wait (if it is the case) the end of all the child process: for example if you run a daemon probably it is not the case to wait it finishes :-).

Note:

• wait ${!} means "wait till the last background process is completed" where $! is the PID of the last background process. So to put wait ${!} just after program_2 & is equivalent to execute directly program_2 without sending it in background with &

• From the help of wait:

  Syntax    
      wait [n ...]
  Key  
      n A process ID or a job specification
  

I believe it's in C:\Windows\System32\WindowsPowershell\v1.0\. In order to confuse the innocent, MS kept it in a directory labeled "v1.0". Running this on Windows 7 and checking the version number via $Host.Version (Determine installed PowerShell version) shows it's 2.0.

Another option is type $PSVersionTable at the command prompt. If you are running v2.0, the output will be:

Name                           Value
----                           -----
CLRVersion                     2.0.50727.4927
BuildVersion                   6.1.7600.16385
PSVersion                      2.0
WSManStackVersion              2.0
PSCompatibleVersions           {1.0, 2.0}
SerializationVersion           1.1.0.1
PSRemotingProtocolVersion      2.1

If you're running version 1.0, the variable doesn't exist and there will be no output.

Localization PowerShell version 1.0, 2.0, 3.0, 4.0:

• 64 bits version: C:\Windows\System32\WindowsPowerShell\v1.0\
• 32 bits version: C:\Windows\SysWOW64\WindowsPowerShell\v1.0\

One way is:

Write-Host "$($assoc.Id)  -  $($assoc.Name)  -  $($assoc.Owner)"

Another one is:

Write-Host  ("{0}  -  {1}  -  {2}" -f $assoc.Id,$assoc.Name,$assoc.Owner )

Or just (but I don't like it ;) ):

Write-Host $assoc.Id  "  -  "   $assoc.Name  "  -  "  $assoc.Owner

Here raw_input is string, so if you wanted to check, if var>3 then you should convert next to double, ie float(next) and do as you would do if float(next)>3:, but in most cases

You have to use new operator here to instantiate. For example:

Contacts.add(new Data(name, address, contact));

Here's what I just did after I realized I was on a detached head and had already made some changes.

I committed the changes.

$ git commit -m "..."
[detached HEAD 1fe56ad] ...

I remembered the hash (1fe56ad) of the commit. Then I checked out the branch I should have been on.

$ git checkout master
Switched to branch 'master'

Finally I applied the changes of the commit to the branch.

$ git cherry-pick 1fe56ad
[master 0b05f1e] ...

I think this is a bit easier than creating a temporary branch.

You need to use split("");.

That will split it by every character.

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

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

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

You can access any DGV cell as follows :

dataGridView1.Rows[rowIndex].Cells[columnIndex].Value = value;

But usually it's better to use databinding : you bind the DGV to a data source (DataTable, collection...) through the DataSource property, and only work on the data source itself. The DataGridView will automatically reflect the changes, and changes made on the DataGridView will be reflected on the data source

I ran

docker info | grep Name: | xargs | cut -d' ' -f2

inside my container.

If you want to call them like that, you should declare them static.

I had very similar situation (had a project on another machine and cloned it to my laptop and saw the same issue) and I looked in it.

Error message was coming from Sdk.groovy of Android gradle plugin: https://android.googlesource.com/platform/tools/build/+/master/gradle/src/main/groovy/com/android/build/gradle/internal/Sdk.groovy

By looking at code, its findLocation needs to set androidSdkDir variable and there are only three ways to do it:

• create local.properties file and have either sdk.dir or android.dir line.
• have ANDROID_HOME environment variable defined.
• System.getProperty("android.home") - I'm not sure how it works, but it seems like a Java thing.

While your Android Studio knows that the SDK is at that place, I doubt that Android Studio is passing that information to gradle and thus we're seeing that error.

I created local.properties file at the project root and put the following line and it compiled the code successfully.

sdk.dir = /Applications/Android Studio.app/sdk/

If you are using WebApi, HttpResponseMessage is a more elegant way to do it

public HttpResponseMessage Get()
{
    return Request.CreateResponse(HttpStatusCode.OK, ListOfMyObject);
}

echo '\x12\x02'

will not be interpreted, and will literally write the string \x12\x02 (and append a newline) to the specified serial port. Instead use

echo -n ^R^B

which you can construct on the command line by typing CtrlVCtrlR and CtrlVCtrlB. Or it is easier to use an editor to type into a script file.

The stty command should work, unless another program is interfering. A common culprit is gpsd which looks for GPS devices being plugged in.

If message.value[] is string:

if message.value[0] in ('/', '\'):
    do_stuff()

If it not str

Many answers already, but one more option

PyPSExec https://pypi.org/project/pypsexec/

It's a python clone of the famous psexec. Works without any installation on the remote windows machine.

installing express globally will not work on your local project so you need to install it locally for use .

npm install express

Hope this will work

Thank you

First I had to delete the python folders in hidden folder user/appData (that was creating huge headaches), in addition to uninstalling Python. Then I installed WinPython Distribution: http://code.google.com/p/winpython/ which includes PIL

                    android:layout_below="@+id/rl_delivery_type" >
                </com.example.util.NestedListView>

In Java:

    private int listViewTouchAction;
    private static final int MAXIMUM_LIST_ITEMS_VIEWABLE = 99;

    public NestedListView(Context context, AttributeSet attrs) {

For upload:

An official list of mime types can be found at The Internet Assigned Numbers Authority (IANA) . According to their list Content-Type header for zip is application/zip.

The media type for rar files is not officially registered at IANA but the unofficial commonly used mime-type value is application/x-rar-compressed.

application/octet-stream means as much as: "I send you a file stream and the content of this stream is not specified" (so it is true that it can be a zip or rar file as well). The server is supposed to detect what the actual content of the stream is.

Note: For upload it is not safe to rely on the mime type set in the Content-Type header. The header is set on the client and can be set to any random value. Instead you can use the php file info functions to detect the file mime-type on the server.

For download:

If you want to download a zip file and nothing else you should only set one single Accept header value. Any additional values set will be used as a fallback in case the server cannot satisfy your in the Accept header requested mime-type.

According to the WC3 specifications this:

application/zip, application/octet-stream 

will be intrepreted as: "I prefer a application/zip mime-type, but if you cannot deliver this an application/octet-stream (a file stream) is also fine".

So only a single:

application/zip

Will guarantee you a zip file (or a 406 - Not Acceptable response in case the server is unable to satisfy your request).

static value may exists into a function and can be used in different forms and can have different value in the program. Also during program after increment of decrement their value may change but const in constant during the whole program.

Here is an explanation of the crontab format.

# 1. Entry: Minute when the process will be started [0-60]
# 2. Entry: Hour when the process will be started [0-23]
# 3. Entry: Day of the month when the process will be started [1-28/29/30/31]
# 4. Entry: Month of the year when the process will be started [1-12]
# 5. Entry: Weekday when the process will be started [0-6] [0 is Sunday]
#
# all x min = */x

So according to this your 5 8 * * 0 would run 8:05 every Sunday.

Looks like I am late to the party, but try the below solution which I personally found the best solution:

var x = "testing sub string"
alert(x[0]);
alert(x[1]);

Output should show alert with below values: "t" "e"

UPDATE For Android v19+ see this link via @Sandra

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

enter_from_left.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
     android:shareInterpolator="false">
  <translate 
      android:fromXDelta="-100%p" android:toXDelta="0%"
      android:fromYDelta="0%" android:toYDelta="0%"
      android:duration="@android:integer/config_mediumAnimTime"/>
</set>

enter_from_right.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
     android:shareInterpolator="false">
  <translate
     android:fromXDelta="100%p" android:toXDelta="0%"
     android:fromYDelta="0%" android:toYDelta="0%"
     android:duration="@android:integer/config_mediumAnimTime" />
</set>

exit_to_left.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
     android:shareInterpolator="false">
  <translate 
      android:fromXDelta="0%" android:toXDelta="-100%p"
      android:fromYDelta="0%" android:toYDelta="0%"
      android:duration="@android:integer/config_mediumAnimTime"/>
</set>

exit_to_right.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
     android:shareInterpolator="false">
  <translate
     android:fromXDelta="0%" android:toXDelta="100%p"
     android:fromYDelta="0%" android:toYDelta="0%"
     android:duration="@android:integer/config_mediumAnimTime" />
</set>

you can change the duration to short animation time

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

or long animation time

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

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

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

• git reset is specifically about updating the index, moving the HEAD.
• git checkout is about updating the working tree (to the index or the specified tree). It will update the HEAD only if you checkout a branch (if not, you end up with a detached HEAD).
  (actually, with Git 2.23 Q3 2019, this will be git restore, not necessarily git checkout)

By comparison, since svn has no index, only a working tree, svn checkout will copy a given revision on a separate directory.
The closer equivalent for git checkout would:

• svn update (if you are in the same branch, meaning the same SVN URL)
• svn switch (if you checkout for instance the same branch, but from another SVN repo URL)

All those three working tree modifications (svn checkout, update, switch) have only one command in git: git checkout.
But since git has also the notion of index (that "staging area" between the repo and the working tree), you also have git reset.

Thinkeye mentions in the comments the article "Reset Demystified ".

For instance, if we have two branches, 'master' and 'develop' pointing at different commits, and we're currently on 'develop' (so HEAD points to it) and we run git reset master, 'develop' itself will now point to the same commit that 'master' does.

On the other hand, if we instead run git checkout master, 'develop' will not move, HEAD itself will. HEAD will now point to 'master'.

So, in both cases we're moving HEAD to point to commit A, but how we do so is very different. reset will move the branch HEAD points to, checkout moves HEAD itself to point to another branch.

On those points, though:

LarsH adds in the comments:

The first paragraph of this answer, though, is misleading: "git checkout ... will update the HEAD only if you checkout a branch (if not, you end up with a detached HEAD)".
Not true: git checkout will update the HEAD even if you checkout a commit that's not a branch (and yes, you end up with a detached HEAD, but it still got updated).

git checkout a839e8f updates HEAD to point to commit a839e8f.

De Novo concurs in the comments:

@LarsH is correct.
The second bullet has a misconception about what HEAD is in will update the HEAD only if you checkout a branch.
HEAD goes wherever you are, like a shadow.
Checking out some non-branch ref (e.g., a tag), or a commit directly, will move HEAD. Detached head doesn't mean you've detached from the HEAD, it means the head is detached from a branch ref, which you can see from, e.g., git log --pretty=format:"%d" -1.

• Attached head states will start with (HEAD ->,
• detached will still show (HEAD, but will not have an arrow to a branch ref.

Hey how about to copy all fields, change one of them to the same value + something else.

INSERT INTO Table (foo, bar, Event_ID)
SELECT foo, bar, Event_ID+"155"
  FROM Table

if you want enable any extension then you have to install an extension first, extension maybe enabled but not installed so, taking example of bcmath

1.yum search php-bcmath

2.then ensure php version in which u want to install this extension

3.u will get output like after yum search command>>

In your link function, do this:

// link function
function (scope, element, attrs) {
  var myEl = angular.element(element[0].querySelector('.list-scrollable'));
}

Also, in your link function, don't name your scope variable using a $. That is an angular convention that is specific to built in angular services, and is not something that you want to use for your own variables.

In my case, package python-pygments was missed. You can fix it by command:

sudo apt-get install python-pygments

If there is problem with pandoc. You should install pandoc and pandoc-citeproc.

sudo apt-get install pandoc pandoc-citeproc

git revert makes a new commit

git revert simply creates a new commit that is the opposite of an existing commit.

It leaves the files in the same state as if the commit that has been reverted never existed. For example, consider the following simple example:

$ cd /tmp/example
$ git init
Initialized empty Git repository in /tmp/example/.git/
$ echo "Initial text" > README.md
$ git add README.md
$ git commit -m "initial commit"
[master (root-commit) 3f7522e] initial commit
 1 file changed, 1 insertion(+)
 create mode 100644 README.md
$ echo "bad update" > README.md 
$ git commit -am "bad update"
[master a1b9870] bad update
 1 file changed, 1 insertion(+), 1 deletion(-)

In this example the commit history has two commits and the last one is a mistake. Using git revert:

$ git revert HEAD
[master 1db4eeb] Revert "bad update"
 1 file changed, 1 insertion(+), 1 deletion(-)

There will be 3 commits in the log:

$ git log --oneline
1db4eeb Revert "bad update"
a1b9870 bad update
3f7522e initial commit

So there is a consistent history of what has happened, yet the files are as if the bad update never occured:

cat README.md 
Initial text

It doesn't matter where in the history the commit to be reverted is (in the above example, the last commit is reverted - any commit can be reverted).

Closing questions

do you have to do something else after?

A git revert is just another commit, so e.g. push to the remote so that other users can pull/fetch/merge the changes and you're done.

Do you have to commit the changes revert made or does revert directly commit to the repo?

git revert is a commit - there are no extra steps assuming reverting a single commit is what you wanted to do.

Obviously you'll need to push again and probably announce to the team.

Indeed - if the remote is in an unstable state - communicating to the rest of the team that they need to pull to get the fix (the reverting commit) would be the right thing to do :).

I would like to add another way of changing a character in a string.

>>> text = '~~~~~~~~~~~'
>>> text = text[:1] + (text[1:].replace(text[0], '+', 1))
'~+~~~~~~~~~'

How faster it is when compared to turning the string into list and replacing the ith value then joining again?.

List approach

>>> timeit.timeit("text = '~~~~~~~~~~~'; s = list(text); s[1] = '+'; ''.join(s)", number=1000000)
0.8268570480013295

My solution

>>> timeit.timeit("text = '~~~~~~~~~~~'; text=text[:1] + (text[1:].replace(text[0], '+', 1))", number=1000000)
0.588400217000526

For Python version 3:

pip install pysqlite3 

Calendar calendar = Calendar.getInstance();

DatePickerDialog datePickerDialog = new DatePickerDialog(getActivity(), R.style.DatePickerDialogTheme, new DatePickerDialog.OnDateSetListener() {
  public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
    Calendar newDate = Calendar.getInstance();
    newDate.set(year, monthOfYear, dayOfMonth);

    SimpleDateFormat simpleDateFormat = new SimpleDateFormat("dd-MM-yyyy");
    String date = simpleDateFormat.format(newDate.getTime());
  }
}, calendar.get(Calendar.YEAR), calendar.get(Calendar.MONTH), calendar.get(Calendar.DAY_OF_MONTH));

datePickerDialog.show();

And use this style:

<style name="DatePickerDialogTheme" parent="Theme.AppCompat.Light.Dialog">
  <item name="colorAccent">@color/colorPrimary</item>
</style>

var inputs = document.getElementsByTagName('input');
for (var i = 0; i < inputs.length; ++i) {
  // ...
}

You must specify the full path of the resource file as the name of 'image within the resources of your application, see example below.

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
    PictureBox1.Image = My.Resources.Chrysanthemum
End Sub

In the path assigned to the Image property after MyResources specify the name of the resource.

But before you do whatever you have to import in the resource section of your application from an image file exists or it can create your own.

Bye

Im not sure if this is the answer you are expecting but, why don't you set the width of Tree to 'auto' and width of 'View' to 100% ?

It is 2021, time to do better than Commons CLI... :-)

Should you build your own Java command line parser, or use a library?

Many small utility-like applications probably roll their own command line parsing to avoid the additional external dependency. picocli may be an interesting alternative.

Picocli is a modern library and framework for building powerful, user-friendly, GraalVM-enabled command line apps with ease. It lives in 1 source file so apps can include it as source to avoid adding a dependency.

It supports colors, autocompletion, subcommands, and more. Written in Java, usable from Groovy, Kotlin, Scala, etc.

Features:

• Annotation based: declarative, avoids duplication and expresses programmer intent
• Convenient: parse user input and run your business logic with one line of code
• Strongly typed everything - command line options as well as positional parameters
• POSIX clustered short options (<command> -xvfInputFile as well as <command> -x -v -f InputFile)
• Fine-grained control: an arity model that allows a minimum, maximum and variable number of parameters, e.g, "1..*", "3..5"
• Subcommands (can be nested to arbitrary depth)
• Feature-rich: composable arg groups, splitting quoted args, repeatable subcommands, and many more
• User-friendly: usage help message uses colors to contrast important elements like option names from the rest of the usage help to reduce the cognitive load on the user
• Distribute your app as a GraalVM native image
• Works with Java 5 and higher
• Extensive and meticulous documentation

The usage help message is easy to customize with annotations (without programming). For example:

(source)

I couldn't resist adding one more screenshot to show what usage help messages are possible. Usage help is the face of your application, so be creative and have fun!

Disclaimer: I created picocli. Feedback or questions very welcome.

I had the same issue when upgrading from Tomcat 7 to 8: a continuous large flood of log warnings about cache.

1. Short Answer

Add this within the Context xml element of your $CATALINA_BASE/conf/context.xml:

<!-- The default value is 10240 kbytes, even when not added to context.xml.
So increase it high enough, until the problem disappears, for example set it to 
a value 5 times as high: 51200. -->
<Resources cacheMaxSize="51200" />

So the default is 10240 (10 mbyte), so set a size higher than this. Than tune for optimum settings where the warnings disappear. Note that the warnings may come back under higher traffic situations.

1.1 The cause (short explanation)

The problem is caused by Tomcat being unable to reach its target cache size due to cache entries that are less than the TTL of those entries. So Tomcat didn't have enough cache entries that it could expire, because they were too fresh, so it couldn't free enough cache and thus outputs warnings.

The problem didn't appear in Tomcat 7 because Tomcat 7 simply didn't output warnings in this situation. (Causing you and me to use poor cache settings without being notified.)

The problem appears when receiving a relative large amount of HTTP requests for resources (usually static) in a relative short time period compared to the size and TTL of the cache. If the cache is reaching its maximum (10mb by default) with more than 95% of its size with fresh cache entries (fresh means less than less than 5 seconds in cache), than you will get a warning message for each webResource that Tomcat tries to load in the cache.

1.2 Optional info

Use JMX if you need to tune cacheMaxSize on a running server without rebooting it.

The quickest fix would be to completely disable cache: <Resources cachingAllowed="false" />, but that's suboptimal, so increase cacheMaxSize as I just described.

2. Long Answer

2.1 Background information

A WebSource is a file or directory in a web application. For performance reasons, Tomcat can cache WebSources. The maximum of the static resource cache (all resources in total) is by default 10240 kbyte (10 mbyte). A webResource is loaded into the cache when the webResource is requested (for example when loading a static image), it's then called a cache entry. Every cache entry has a TTL (time to live), which is the time that the cache entry is allowed to stay in the cache. When the TTL expires, the cache entry is eligible to be removed from the cache. The default value of the cacheTTL is 5000 milliseconds (5 seconds).

There is more to tell about caching, but that is irrelevant for the problem.

2.2 The cause

The following code from the Cache class shows the caching policy in detail:

152  // Content will not be cached but we still need metadata size
153  long delta = cacheEntry.getSize();
154  size.addAndGet(delta);
156  if (size.get() > maxSize) {
157      // Process resources unordered for speed. Trades cache
158      // efficiency (younger entries may be evicted before older
159      // ones) for speed since this is on the critical path for
160      // request processing
161      long targetSize =
162              maxSize * (100 - TARGET_FREE_PERCENT_GET) / 100;
163      long newSize = evict(
164              targetSize, resourceCache.values().iterator());
165      if (newSize > maxSize) {
166          // Unable to create sufficient space for this resource
167          // Remove it from the cache
168          removeCacheEntry(path);
169          log.warn(sm.getString("cache.addFail", path));
170      }
171  }

When loading a webResource, the code calculates the new size of the cache. If the calculated size is larger than the default maximum size, than one or more cached entries have to be removed, otherwise the new size will exceed the maximum. So the code will calculate a "targetSize", which is the size the cache wants to stay under (as an optimum), which is by default 95% of the maximum. In order to reach this targetSize, entries have to be removed/evicted from the cache. This is done using the following code:

215  private long evict(long targetSize, Iterator<CachedResource> iter) {
217      long now = System.currentTimeMillis();
219      long newSize = size.get();
221      while (newSize > targetSize && iter.hasNext()) {
222          CachedResource resource = iter.next();
224          // Don't expire anything that has been checked within the TTL
225          if (resource.getNextCheck() > now) {
226              continue;
227          }
229          // Remove the entry from the cache
230          removeCacheEntry(resource.getWebappPath());
232          newSize = size.get();
233      }
235      return newSize;
236  }

So a cache entry is removed when its TTL is expired and the targetSize hasn't been reached yet.

After the attempt to free cache by evicting cache entries, the code will do:

165  if (newSize > maxSize) {
166      // Unable to create sufficient space for this resource
167      // Remove it from the cache
168      removeCacheEntry(path);
169      log.warn(sm.getString("cache.addFail", path));
170  }

So if after the attempt to free cache, the size still exceeds the maximum, it will show the warning message about being unable to free:

cache.addFail=Unable to add the resource at [{0}] to the cache for web application [{1}] because there was insufficient free space available after evicting expired cache entries - consider increasing the maximum size of the cache

2.3 The problem

So as the warning message says, the problem is

insufficient free space available after evicting expired cache entries - consider increasing the maximum size of the cache

If your web application loads a lot of uncached webResources (about maximum of cache, by default 10mb) within a short time (5 seconds), then you'll get the warning.

The confusing part is that Tomcat 7 didn't show the warning. This is simply caused by this Tomcat 7 code:

1606  // Add new entry to cache
1607  synchronized (cache) {
1608      // Check cache size, and remove elements if too big
1609      if ((cache.lookup(name) == null) && cache.allocate(entry.size)) {
1610          cache.load(entry);
1611      }
1612  }

combined with:

231  while (toFree > 0) {
232      if (attempts == maxAllocateIterations) {
233          // Give up, no changes are made to the current cache
234          return false;
235      }

So Tomcat 7 simply doesn't output any warning at all when it's unable to free cache, whereas Tomcat 8 will output a warning.

So if you are using Tomcat 8 with the same default caching configuration as Tomcat 7, and you got warnings in Tomcat 8, than your (and mine) caching settings of Tomcat 7 were performing poorly without warning.

2.4 Solutions

There are multiple solutions:

1. Increase cache (recommended)
2. Lower the TTL (not recommended)
3. Suppress cache log warnings (not recommended)
4. Disable cache

2.4.1. Increase cache (recommended)

As described here: http://tomcat.apache.org/tomcat-8.0-doc/config/resources.html

By adding <Resources cacheMaxSize="XXXXX" /> within the Context element in $CATALINA_BASE/conf/context.xml, where "XXXXX" stands for an increased cache size, specified in kbytes. The default is 10240 (10 mbyte), so set a size higher than this.

You'll have to tune for optimum settings. Note that the problem may come back when you suddenly have an increase in traffic/resource requests.

To avoid having to restart the server every time you want to try a new cache size, you can change it without restarting by using JMX.

To enable JMX, add this to $CATALINA_BASE/conf/server.xml within the Server element: <Listener className="org.apache.catalina.mbeans.JmxRemoteLifecycleListener" rmiRegistryPortPlatform="6767" rmiServerPortPlatform="6768" /> and download catalina-jmx-remote.jar from https://tomcat.apache.org/download-80.cgi and put it in $CATALINA_HOME/lib. Then use jConsole (shipped by default with the Java JDK) to connect over JMX to the server and look through the settings for settings to increase the cache size while the server is running. Changes in these settings should take affect immediately.

2.4.2. Lower the TTL (not recommended)

Lower the cacheTtl value by something lower than 5000 milliseconds and tune for optimal settings.

For example: <Resources cacheTtl="2000" />

This comes effectively down to having and filling a cache in ram without using it.

2.4.3. Suppress cache log warnings (not recommended)

Configure logging to disable the logger for org.apache.catalina.webresources.Cache.

For more info about logging in Tomcat: http://tomcat.apache.org/tomcat-8.0-doc/logging.html

2.4.4. Disable cache

You can disable the cache by setting cachingAllowed to false. <Resources cachingAllowed="false" />

Although I can remember that in a beta version of Tomcat 8, I was using JMX to disable the cache. (Not sure why exactly, but there may be a problem with disabling the cache via server.xml.)

I had a dict in my list, so I could not use the above approach. I got the error:

TypeError: unhashable type:

So if you care about order and/or some items are unhashable. Then you might find this useful:

def make_unique(original_list):
    unique_list = []
    [unique_list.append(obj) for obj in original_list if obj not in unique_list]
    return unique_list

Some may consider list comprehension with a side effect to not be a good solution. Here's an alternative:

def make_unique(original_list):
    unique_list = []
    map(lambda x: unique_list.append(x) if (x not in unique_list) else False, original_list)
    return unique_list

very simple I don't have the structure of Data and Commits So I changed the

package main

import (
    "fmt"
)

type Project struct {
    Id      int64   `json:"project_id"`
    Title   string  `json:"title"`
    Name    string  `json:"name"`
    Data    string  `json:"data"`
    Commits string  `json:"commits"`
}

func main() {
    p := Project{
    1,
    "First",
    "Ankit",
    "your data",
    "Commit message",
    }
    fmt.Println(p)
}

You cannot start a container from a Dockerfile.

The process goes like this:

Dockerfile =[docker build]=> Docker image =[docker run]=> Docker container

To start (or run) a container you need an image. To create an image you need to build the Dockerfile[1].

[1]: you can also docker import an image from a tarball or again docker load.

with your toolbar you can solve that problem. use setTitle method.

 Toolbar   mToolbar = (Toolbar) findViewById(R.id.toolbar);
  mToolbar.setTitle("");
  setSupportActionBar(mToolbar);

super easy :)

Maybe python changed since this question, all of the below seem to work well

Python2.7

int(1324343032.324325235 * 1000) / 1000.0
float(int(1324343032.324325235 * 1000)) / 1000
round(int(1324343032.324325235 * 1000) / 1000.0,3)
# result for all of the above is 1324343032.324

Piggy backing off of user1927494's answer, In case you want to run a single test before all others, you can do this:

@Test()
public void testOrderDoesntMatter_1() {
}

@Test(priority=-1)
public void testToRunFirst() {
}

@Test()
public void testOrderDoesntMatter_2() {
}

This question has been asked long ago but none of the answers above helped me out, though Milad Moosavi`s answer was very close. To open a new activity from a certain position on the recycler view, the following code may help:

    @Override
    public void onBindViewHolder(@NonNull TripViewHolder holder, int position) {
        Trip currentTrip = trips.get(position);

        holder.itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent intent = new Intent(v.getContext(), EditTrip.class);
                v.getContext().startActivity(intent);
            }
        });

        holder.itemView.setOnLongClickListener(new View.OnLongClickListener() {
            @Override
            public boolean onLongClick(View v) {
                Intent intent = new Intent(v.getContext(), ReadTripActivity.class);
                v.getContext().startActivity(intent);

                return false;
            }
        });
    }

you can set them in the body tag

body
{
    font-size:xxx;
    font-family:yyyy;
}

URL rewriting could be used to map a URL to .php files. The following rules can identify whether a .php request was made directly or it was re-written. It forbids the request in the first case:

RewriteEngine On
RewriteCond %{THE_REQUEST} ^.+?\ [^?]+\.php[?\ ]
RewriteRule \.php$ - [F]
RewriteRule test index.php

These rules will forbid all requests that end with .php. However, URLs such as / (which fires index.php), /test (which rewrites to index.php) and /test?f=index.php (which contains index.php in querystring) are still allowed.

THE_REQUEST contains the full HTTP request line sent by the browser to the server (e.g., GET /index.php?foo=bar HTTP/1.1)

The smallest change to fix this would be to change

onClick="document.getElementById("datepicker").click()">

to

onClick="$('#datepicker').click()">

click() is a jQuery method. Also, you had a collision between the double-quotes used for the HTML element attribute and those use for the JavaScript function argument.

i wanted to mention Jailbreak specifically (GitHub):

Jailbreak

Jailbreak is a tool for exporting certificates marked as non-exportable from the Windows certificate store. This can help when you need to extract certificates for backup or testing. You must have full access to the private key on the filesystem in order for jailbreak to work.

Prerequisites: Win32

You need to allocate new space as well. Consider this code fragment:

char * new_str ;
if((new_str = malloc(strlen(str1)+strlen(str2)+1)) != NULL){
    new_str[0] = '\0';   // ensures the memory is an empty string
    strcat(new_str,str1);
    strcat(new_str,str2);
} else {
    fprintf(STDERR,"malloc failed!\n");
    // exit?
}

You might want to consider strnlen(3) which is slightly safer.

Updated, see above. In some versions of the C runtime, the memory returned by malloc isn't initialized to 0. Setting the first byte of new_str to zero ensures that it looks like an empty string to strcat.

You could also do

SELECT row FROM table ORDER BY id DESC LIMIT 1;

This will sort rows by their ID in descending order and return the first row. This is the same as returning the row with the maximum ID. This of course assumes that id is unique among all rows. Otherwise there could be multiple rows with the maximum value for id and you'll only get one.

If you use the Angular CLI to create your components, let's say CarComponent, it attaches app to the selector name (i.e app-car) and this throws the above error when you reference the component in the parent view. Therefore you either have to change the selector name in the parent view to let's say <app-car></app-car> or change the selector in the CarComponent to selector: 'car'

I had the same issue today using primefaces (primeng) and angular 7. Add the following to your style.css

p-button {
   -webkit-appearance: none !important;
}

i am also using a bit of bootstrap which has a reboot.css, that overrides it with (thats why i had to add !important)

button {
  -webkit-appearance: button;

}

Updated with feedback from Alan Moore

In PCRE and similar variants, you can actually create a regex that matches any line not containing a value:

^(?:(?!Andrea).)*$

This is called a tempered greedy token. The downside is that it doesn't perform well.

The variable in the for loop is an integer sequence, and so eventually you do this:

> y=as.integer(60000)*as.integer(60000)
Warning message:
In as.integer(60000) * as.integer(60000) : NAs produced by integer overflow

whereas in the while loop you are creating a floating point number.

Its also the reason these things are different:

> seq(0,2,1)
[1] 0 1 2
> seq(0,2)
[1] 0 1 2

Don't believe me?

> identical(seq(0,2),seq(0,2,1))
[1] FALSE

because:

> is.integer(seq(0,2))
[1] TRUE
> is.integer(seq(0,2,1))
[1] FALSE

I find that Wikipedia can be a great source of information about such tools, especially for comparison tables. There's a page on UML tools. See in particular the reverse engineered languages column.

The --bare flag creates a repository that doesn’t have a working directory. The bare repository is the central repository and you can't edit(store) codes here for avoiding the merging error.

For example, when you add a file in your local repository (machine 1) and push it to the bare repository, you can't see the file in the bare repository for it is always 'empty'. However, you really push something to the repository and you can see it inexplicitly by cloning another repository in your server(machine 2).

Both the local repository in machine 1 and the 'copy' repository in machine 2 are non-bare. relationship between bare and non-bare repositories

You have a problem one way or the other with your datetime.datetime.fromtimestamp(time.mktime(time.gmtime())) expression.

(1) If all you need is the difference between two instants in seconds, the very simple time.time() does the job.

(2) If you are using those timestamps for other purposes, you need to consider what you are doing, because the result has a big smell all over it:

gmtime() returns a time tuple in UTC but mktime() expects a time tuple in local time.

I'm in Melbourne, Australia where the standard TZ is UTC+10, but daylight saving is still in force until tomorrow morning so it's UTC+11. When I executed the following, it was 2011-04-02T20:31 local time here ... UTC was 2011-04-02T09:31

>>> import time, datetime
>>> t1 = time.gmtime()
>>> t2 = time.mktime(t1)

You'll notice that t3, the result of your expression is UTC+1, which appears to be UTC + (my local DST difference) ... not very meaningful. You should consider using datetime.datetime.utcnow() which won't jump by an hour when DST goes on/off and may give you more precision than time.time()

F=code.c
REV=123
svn diff -c $REV $F | patch -R -p0 \
    && svn commit -m "undid rev $REV" $F

If not working in any case...then delete your project from the Eclipse workspace and again import as a Maven project if that is a Maven project. Else import as an existing project.

I tried all the previous given solutions, but they didn't work, but it works for me.

Use command:

git tag v1.0 ec32d32

Where v1.0 is the tag name and ec32d32 is the commit you want to tag

Once done you can push the tags by:

git push origin --tags

I benchmarked the answers of Anthony Damico, Brian Diggs and data_steve on a small sample tbl_df and got the following results.

+                    'b' = c('a','b','c'), 
+                    'c' = c('d', 'e', 'f'), 
+                    'd' = c('g', 'h', 'i'))
> data <- tbl_df(data)
> cols <- c("b", "c", "d")
> microbenchmark(

+     apply( data[ , cols ] , 1 , paste , collapse = "-" ),

I had this issue too on a project I'd just checked out from source control.

The symptom was the error described above and a yellow warning triangle on a reference to System.Net.Http.Formatting

To fix this, I removed the broken reference and then used NuGet to install the latest version of Microsoft.AspNet.WebApi.Client.

var seconds = 0;
setInterval(function () {
  seconds++;
}, 1000);

There you go, now you have a variable counting seconds elapsed. Since I don't know the context, you'll have to decide whether you want to attach that variable to an object or make it global.

Set interval is simply a function that takes a function as it's first parameter and a number of milliseconds to repeat the function as it's second parameter.

You could also solve this by saving and comparing times.

EDIT: This answer will provide very inconsistent results due to things such as the event loop and the way browsers may choose to pause or delay processing when a page is in a background tab. I strongly recommend using the accepted answer.

Import division from future library like this:

from__future__ import division

While using TOP or a sub-query both work, I would break the problem into steps:

Find target record

SELECT MIN( date ) AS date, id
FROM myTable
WHERE id = 2
GROUP BY id

Join to get other fields

SELECT mt.id, mt.name, mt.score, mt.date
FROM myTable mt
INNER JOIN
( 
   SELECT MIN( date ) AS date, id
   FROM myTable
   WHERE id = 2
   GROUP BY id
) x ON x.date = mt.date AND x.id = mt.id

While this solution, using derived tables, is longer, it is:

• Easier to test
• Self documenting
• Extendable

It is easier to test as parts of the query can be run standalone.

It is self documenting as the query directly reflects the requirement ie the derived table lists the row where id = 2 with the earliest date.

It is extendable as if another condition is required, this can be easily added to the derived table.

I got it because I wasn't using[self performSegueWithIdentifier:sender:] and -(void) prepareForSegue:(UIstoryboardSegue *) right

success has been the traditional name of the success callback in jQuery, defined as an option in the ajax call. However, since the implementation of $.Deferreds and more sophisticated callbacks, done is the preferred way to implement success callbacks, as it can be called on any deferred.

For example, success:

$.ajax({
  url: '/',
  success: function(data) {}
});

For example, done:

$.ajax({url: '/'}).done(function(data) {});

The nice thing about done is that the return value of $.ajax is now a deferred promise that can be bound to anywhere else in your application. So let's say you want to make this ajax call from a few different places. Rather than passing in your success function as an option to the function that makes this ajax call, you can just have the function return $.ajax itself and bind your callbacks with done, fail, then, or whatever. Note that always is a callback that will run whether the request succeeds or fails. done will only be triggered on success.

For example:

function xhr_get(url) {

  return $.ajax({
    url: url,
    type: 'get',
    dataType: 'json',
    beforeSend: showLoadingImgFn
  })
  .always(function() {
    // remove loading image maybe
  })
  .fail(function() {
    // handle request failures
  });

}

xhr_get('/index').done(function(data) {
  // do stuff with index data
});

xhr_get('/id').done(function(data) {
  // do stuff with id data
});

An important benefit of this in terms of maintainability is that you've wrapped your ajax mechanism in an application-specific function. If you decide you need your $.ajax call to operate differently in the future, or you use a different ajax method, or you move away from jQuery, you only have to change the xhr_get definition (being sure to return a promise or at least a done method, in the case of the example above). All the other references throughout the app can remain the same.

There are many more (much cooler) things you can do with $.Deferred, one of which is to use pipe to trigger a failure on an error reported by the server, even when the $.ajax request itself succeeds. For example:

function xhr_get(url) {

  return $.ajax({
    url: url,
    type: 'get',
    dataType: 'json'
  })
  .pipe(function(data) {
    return data.responseCode != 200 ?
      $.Deferred().reject( data ) :
      data;
  })
  .fail(function(data) {
    if ( data.responseCode )
      console.log( data.responseCode );
  });
}

xhr_get('/index').done(function(data) {
  // will not run if json returned from ajax has responseCode other than 200
});

Read more about $.Deferred here: http://api.jquery.com/category/deferred-object/

NOTE: As of jQuery 1.8, pipe has been deprecated in favor of using then in exactly the same way.

Here's an example program that will send myfile.mp3 by streaming it from disk (that is, it doesn't read the whole file into memory before sending the file). The server listens on port 2000.

[Update] As mentioned by @Aftershock in the comments, util.pump is gone and was replaced with a method on the Stream prototype called pipe; the code below reflects this.

var http = require('http'),
    fileSystem = require('fs'),
    path = require('path');

http.createServer(function(request, response) {
    var filePath = path.join(__dirname, 'myfile.mp3');
    var stat = fileSystem.statSync(filePath);

    response.writeHead(200, {
        'Content-Type': 'audio/mpeg',
        'Content-Length': stat.size
    });

    var readStream = fileSystem.createReadStream(filePath);
    // We replaced all the event handlers with a simple call to readStream.pipe()
    readStream.pipe(response);
})
.listen(2000);

Swift: iOS
if we have string, convert it to NSDate,

var dataString = profileValue["dob"] as String
var dateFormatter = NSDateFormatter()
dateFormatter.dateFormat = "MM-dd-yyyy"

// convert string into date
let dateValue:NSDate? = dateFormatter.dateFromString(dataString)

if you have and date picker parse date like this

// to avoid any nil value
if let isDate = dateValue {
self.datePicker.date = isDate
}

I had to change:

function start_lvl(&$output, $depth)

to:

function start_lvl( &$output, $depth = 0, $args = array() )

Because I was getting an incompatibility error:

Strict Standards: Declaration of My_Walker_Nav_Menu::start_lvl() should be compatible with Walker_Nav_Menu::start_lvl(&$output, $depth = 0, $args = Array)

Everyone seems to be ignoring the "enum type" portion of your question.

While there is no canonical source for HTTP Status Codes there is an simple way to add any missing Status constants you need to those provided by javax.ws.rs.core.Response.Status without adding any additional dependencies to your project.

javax.ws.rs.core.Response.Status is just one implementation of the javax.ws.rs.core.Response.StatusType interface. You simply need to create your own implementation enum with definitions for the Status Codes that you want.

Core libraries like Javax, Jersey, etc. are written to the interface StatusType not the implementation Status (or they certainly should be). Since your new Status enum implements StatusType it can be used anyplace you would use a javax.ws.rs.core.Response.Status constant.

Just remember that your own code should also be written to the StatusType interface. This will enable you to use both your own Status Codes along side the "standard" ones.

Here's a gist with a simple implementation with constants defined for the "Informational 1xx" Status Codes: https://gist.github.com/avendasora/a5ed9acf6b1ee709a14a

The width is being restricted by the size of the body. If you make the width of the body larger you will see it stays on one line with the background color.

To maintain the minimum width: min-width:100%

Here, in this post you will find the detailed code for establishing socket between devices or between two application in the same mobile.

You have to create two application to test below code.

In both application's manifest file, add below permission

<uses-permission android:name="android.permission.INTERNET" />

For debugging you can also use a "Java Decompiler" such as: JAD and decompile source on the fly (although the generated source is never the same as the original). Then install JAD as a plugin in Eclipse or your favorite IDE.

Variable scope in Ruby is controlled by sigils to some degree. Variables starting with $ are global, variables with @ are instance variables, @@ means class variables, and names starting with a capital letter are constants. All other variables are locals. When you open a class or method, that's a new scope, and locals available in the previous scope aren't available.

I generally prefer to avoid creating global variables. There are two techniques that generally achieve the same purpose that I consider cleaner:

1. Create a constant in a module. So in this case, you would put all the classes that need the offset in the module Foo and create a constant Offset, so then all the classes could access Foo::Offset.

2. Define a method to access the value. You can define the method globally, but again, I think it's better to encapsulate it in a module or class. This way the data is available where you need it and you can even alter it if you need to, but the structure of your program and the ownership of the data will be clearer. This is more in line with OO design principles.

Use the Below Code for that

UPDATE Table1 SET Column1 = LTRIM(RTRIM(REPLACE(REPLACE(REPLACE(Column1, CHAR(9), ''), CHAR(10), ''), CHAR(13), '')))`

For future people CTRL+ALT+D or just view > report data in ancient ssrs 2008 VS BI. In newer 2017 SSRS, it's still the same. Funny how they change a bunch of things around, yet kept this the same.

How about mkString ?

theStrings.mkString(",")

A variant exists in which you can specify a prefix and suffix too.

See here for an implementation using foldLeft, which is much more verbose, but perhaps worth looking at for education's sake.

Although it is not recommended, but if you really want to let your web application access a folder outside its deployment directory. You need to add following permission in java.policy file (path is as in the reply of Petey B)

permission java.io.FilePermission "your folder path", "write"

In your case it would be

permission java.io.FilePermission "S:/PDSPopulatingProgram/-", "write"

Here /- means any files or sub-folders inside this folder.

Warning: But by doing this, you are inviting some security risk.

Value for network.proxy.http_port should be integer (no quotes should be used) and network.proxy.type should be set as 1 (ProxyType.MANUAL, Manual proxy settings)

FirefoxProfile profile = new FirefoxProfile();
profile.setPreference("network.proxy.type", 1);
profile.setPreference("network.proxy.http", "localhost");
profile.setPreference("network.proxy.http_port", 3128);
WebDriver driver = new FirefoxDriver(profile);

I've reduced your code sample to the following lines to make it easier to understand the explanation of the concept.

var results = [];
var config = JSON.parse(queries);
for (var key in config) {
    var query = config[key].query;
    search(query, function(result) {
        results.push(result);
    });
}
res.writeHead( ... );
res.end(results);

The problem with the previous code is that the search function is asynchronous, so when the loop has ended, none of the callback functions have been called. Consequently, the list of results is empty.

To fix the problem, you have to put the code after the loop in the callback function.

    search(query, function(result) {
        results.push(result);
        // Put res.writeHead( ... ) and res.end(results) here
    });

However, since the callback function is called multiple times (once for every iteration), you need to somehow know that all callbacks have been called. To do that, you need to count the number of callbacks, and check whether the number is equal to the number of asynchronous function calls.

To get a list of all keys, use Object.keys. Then, to iterate through this list, I use .forEach (you can also use for (var i = 0, key = keys[i]; i < keys.length; ++i) { .. }, but that could give problems, see JavaScript closure inside loops – simple practical example).

Here's a complete example:

var results = [];
var config = JSON.parse(queries);
var onComplete = function() {
    res.writeHead( ... );
    res.end(results);
};
var keys = Object.keys(config);
var tasksToGo = keys.length;
if (tasksToGo === 0) {
   onComplete();
} else {
    // There is at least one element, so the callback will be called.
    keys.forEach(function(key) {
        var query = config[key].query;
        search(query, function(result) {
            results.push(result);
            if (--tasksToGo === 0) {
                // No tasks left, good to go
                onComplete();
            }
        });
    });
}

Note: The asynchronous code in the previous example are executed in parallel. If the functions need to be called in a specific order, then you can use recursion to get the desired effect:

var results = [];
var config = JSON.parse(queries);
var keys = Object.keys(config);
(function next(index) {
    if (index === keys.length) { // No items left
        res.writeHead( ... );
        res.end(results);
        return;
    }
    var key = keys[index];
    var query = config[key].query;
    search(query, function(result) {
        results.push(result);
        next(index + 1);
    });
})(0);

What I've shown are the concepts, you could use one of the many (third-party) NodeJS modules in your implementation, such as async.

in my case i always put these stuffs in a p tag like

<p> name : < input type=text /> </p>

and so on and then applying the css like

p {
  text-align:left;
}

p input {
  float:right;
}

You need to specify the width of the p tag.because the input tags will float all the way right.

This css will also affect the submit button. You need to override the rule for this tag.

If you are already debugging, you can hover over the function and the tooltip will allow you to navigate directly to the function definition:

Further Reading:

• Chrome DevTools > JavaScript Debugging Reference

function sleep(delay) {
    var start = new Date().getTime();
    while (new Date().getTime() < start + delay);
}

This code blocks for the specified duration. This is CPU hogging code. This is different from a thread blocking itself and releasing CPU cycles to be utilized by another thread. No such thing is going on here. Do not use this code, it's a very bad idea.

date = models.DateTimeField(default=datetime.now, blank=True)

You should all know this is inline scripting and is not a good practice at all...with that said you should definitively use javascript or jQuery for this type of thing:

HTML

<!DOCTYPE html> 
<html> 
 <head> 
    <meta charset="ISO-8859-1"> 
    <title>Online Student Portal</title> 
 </head> 
 <body> 
    <form action="">
         <input type="button" id="myButton" value="Add"/>
    </form> 
 </body> 
</html>

JQuery

var button_my_button = "#myButton";
$(button_my_button).click(function(){
 window.location.href='Students.html';
});

Javascript

  //get a reference to the element
  var myBtn = document.getElementById('myButton');

  //add event listener
  myBtn.addEventListener('click', function(event) {
    window.location.href='Students.html';
  });

See comments why avoid inline scripting and also why inline scripting is bad

In this post circle line collision will be checked by checking distance between circle center and point on line segment (Ipoint) that represent intersection point between normal N (Image 2) from circle center to line segment.

(https://i.stack.imgur.com/3o6do.png)

On image 1 one circle and one line are shown, vector A point to line start point, vector B point to line end point, vector C point to circle center. Now we must find vector E (from line start point to circle center) and vector D (from line start point to line end point) this calculation is shown on image 1.

(https://i.stack.imgur.com/7098a.png)

At image 2 we can see that vector E is projected on Vector D by "dot product" of vector E and unit vector D, result of dot product is scalar Xp that represent the distance between line start point and point of intersection (Ipoint) of vector N and vector D. Next vector X is found by multiplying unit vector D and scalar Xp.

Now we need to find vector Z (vector to Ipoint), its easy its simple vector addition of vector A (start point on line) and vector X. Next we need to deal with special cases we must check is Ipoint on line segment, if its not we must find out is it left of it or right of it, we will use vector closest to determine which point is closest to circle.

(https://i.stack.imgur.com/p9WIr.png)

When projection Xp is negative Ipoint is left of line segment, vector closest is equal to vector of line start point, when projection Xp is greater then magnitude of vector D then Ipoint is right of line segment then closest vector is equal to vector of line end point in any other case closest vector is equal to vector Z.

Now when we have closest vector , we need to find vector from circle center to Ipoint (dist vector), its simple we just need to subtract closest vector from center vector. Next just check if vector dist magnitude is less then circle radius if it is then they collide, if its not there is no collision.

(https://i.stack.imgur.com/QJ63q.png)

For end, we can return some values for resolving collision , easiest way is to return overlap of collision (subtract radius from vector dist magnitude) and return axis of collision, its vector D. Also intersection point is vector Z if needed.

 object instanceof Type

is true if the object is a Type or a subclass of Type

 object.getClass().equals(Type.class) 

is true only if the object is a Type

Set and Get methods are a pattern of data encapsulation. Instead of accessing class member variables directly, you define get methods to access these variables, and set methods to modify them. By encapsulating them in this manner, you have control over the public interface, should you need to change the inner workings of the class in the future.

For example, for a member variable:

Integer x;

You might have methods:

Integer getX(){ return x; }
void setX(Integer x){ this.x = x; }

chiccodoro also mentioned an important point. If you only want to allow read access to the field for any foreign classes, you can do that by only providing a public get method and keeping the set private or not providing a set at all.

In Kotlin, use the following codes to get Application Name:

        // Get App Name
        var appName: String = ""
        val applicationInfo = this.getApplicationInfo()
        val stringId = applicationInfo.labelRes
        if (stringId == 0) {
            appName = applicationInfo.nonLocalizedLabel.toString()
        }
        else {
            appName = this.getString(stringId)
        }

Here's your expected snippet which gives you the array of all the matched values -

var windowArray = new Array ("item","thing","id-3-text","class");_x000D_
_x000D_
var result = [];_x000D_
windowArray.forEach(val => {_x000D_
  if(val && val.includes('id-')) {_x000D_
    result.push(val);_x000D_
  }_x000D_
});_x000D_
_x000D_
console.log(result);

For me I had forgot to add closing quote

/p:DeployOnBuild=true;OutDir="$(build.artifactstagingdirectory)

to

/p:DeployOnBuild=true;OutDir="$(build.artifactstagingdirectory)"

For Swift 3.0:

button.titleLabel?.font = UIFont.boldSystemFont(ofSize: 16)

where "boldSystemFont" and "16" can be replaced with your custom font and size.

Try the following.

string input = "someString";
string[] toSearchFor = GetSearchStrings();
var containsAll = toSearchFor.All(x => input.Contains(x));

Because that's not what strip() does. It removes leading and trailing characters that are present in the argument, but not those characters in the middle of the string.

You could do:

name= name.replace('(', '').replace(')', '').replace ...

or:

name= ''.join(c for c in name if c not in '(){}<>')

or maybe use a regex:

import re
name= re.sub('[(){}<>]', '', name)

This enables you to write something like:

void doSomething() {
    List<String>list = new ArrayList<String>();
    //do something
}

Later on, you might want to change it to:

void doSomething() {
    List<String>list = new LinkedList<String>();
    //do something
}

without having to change the rest of the method.

However, if you want to use a CopyOnWriteArrayList for example, you would need to declare it as such, and not as a List if you wanted to use its extra methods (addIfAbsent for example):

void doSomething() {
    CopyOnWriteArrayList<String>list = new CopyOnWriteArrayList<String>();
    //do something, for example:
    list.addIfAbsent("abc");
}

You can use the padding-left attribute on the list items (not on the list itself!).

you can try adding

$db['db_debug'] = FALSE; 

in "your database file".php after that you can modify your database as you like.

Undoubtedly, for your purposes (which I assume is just a programming exercise), the best thing is to check your results against any of the listings of the digits of pi on the web.

And how do we know that those values are correct? Well, I could say that there are computer-science-y ways to prove that an implementation of an algorithm is correct.

More pragmatically, if different people use different algorithms, and they all agree to (pick a number) a thousand (million, whatever) decimal places, that should give you a warm fuzzy feeling that they got it right.

Historically, William Shanks published pi to 707 decimal places in 1873. Poor guy, he made a mistake starting at the 528th decimal place.

Very interestingly, in 1995 an algorithm was published that had the property that would directly calculate the nth digit (base 16) of pi without having to calculate all the previous digits!

Finally, I hope your initial algorithm wasn't pi/4 = 1 - 1/3 + 1/5 - 1/7 + ... That may be the simplest to program, but it's also one of the slowest ways to do so. Check out the pi article on Wikipedia for faster approaches.

If you would like to use the values, say as part of csvfile csv.writer, the numbers can be formatted before creating a list:

df['label'].apply(lambda x: '%.17f' % x).values.tolist()

Download Microsoft Drivers for PHP for SQL Server. Extract the files and use one of:

File                             Thread Safe         VC Bulid
php_sqlsrv_53_nts_vc6.dll           No                  VC6
php_sqlsrv_53_nts_vc9.dll           No                  VC9
php_sqlsrv_53_ts_vc6.dll            Yes                 VC6
php_sqlsrv_53_ts_vc9.dll            Yes                 VC9

You can see the Thread Safety status in phpinfo().

Add the correct file to your ext directory and the following line to your php.ini:

extension=php_sqlsrv_53_*_vc*.dll

Use the filename of the file you used.

As Gordon already posted this is the new Extension from Microsoft and uses the sqlsrv_* API instead of mssql_*

Update:
On Linux you do not have the requisite drivers and neither the SQLSERV Extension.
Look at Connect to MS SQL Server from PHP on Linux? for a discussion on this.

In short you need to install FreeTDS and YES you need to use mssql_* functions on linux. see update 2

To simplify things in the long run I would recommend creating a wrapper class with requisite functions which use the appropriate API (sqlsrv_* or mssql_*) based on which extension is loaded.

Update 2: You do not need to use mssql_* functions on linux. You can connect to an ms sql server using PDO + ODBC + FreeTDS. On windows, the best performing method to connect is via PDO + ODBC + SQL Native Client since the PDO + SQLSRV driver can be incredibly slow.

Try this

1. npm uninstall angular-cli
2. npm install @angular/cli --save-dev

For me maven seems to work off the .mavenrc file:

echo "export JAVA_HOME=$(/usr/libexec/java_home -v 1.8)" > ~/.mavenrc

I'm sure I picked it up on SO too, just can't remember where.

In my case, it was not only necessary add jenkins user to docker group, but make that group the primary group of the jenkins user.

# usermod -g docker jenkins
# usermod -a -G jenkins jenkins

Don't forget to reconnect the jenkins slave node or restart the jenkins server, depend on your case.

Saw this thread but I wanted to search for IDs that did not match my search. Code to do that:

found = $filter('filter')($scope.fish, {id: '!fish_id'}, false);

This is what I normally do with my projects:

npm version patch
git add *;
git commit -m "Commit message"
git push
npm publish

The first line, npm version patch, will increase the patch version by 1 (x.x.1 to x.x.2) in package.json. Then you add all files -- including package.json which at that point has been modified. Then, the usual git commit and git push, and finally npm publish to publish the module.

I hope this makes sense...

JSONP does not work with basic authentication so the jQuery beforeSend callback won't work with JSONP/Script.

I managed to work around this limitation by adding the user and password to the request (e.g. user:[email protected]). This works with pretty much any browser except Internet Explorer where authentication through URLs is not supported (the call will simply not be executed).

See http://support.microsoft.com/kb/834489.

Yes it remains the same. but why not easily test it? Make an ArrayList, fill it and then retrieve the elements!

You can run flutter clean.

But that's most likely a problem with your IDE or similar, as flutter run creates a brand new apk. And hot reload push only modifications.

Try running your app using the command line flutter run and then press r or R for respectively hot-reload and full-reload.

I am not sure but when we have execute time out or command time out The client sends an "ABORT" to SQL Server then simply abandons the query processing. No transaction is rolled back, no locks are released. to solve this problem I Remove transaction in Stored-procedure and use SQL Transaction in my .Net Code To manage sqlException

For xcode 8.3.3 I just checked tried the above code and observe that, now in this casewe have to change the commands to like this

first you can create a .gitignore file by using

 touch .gitignore

after that you can delete all the userInterface file by using this command and by using this command it will respect your .gitignore file.

 git rm --cached [project].xcworkspace/xcuserdata/[username].xcuserdatad/UserInterfaceState.xcuserstate
 git commit -m "Removed file that shouldn't be tracked"

You can escape " with \

var text="\"word\"";

http://jsfiddle.net/beKpE/

Add the following line on the top of your file

require 'json'

Then you can use:

car = {:make => "bmw", :year => "2003"}
car.to_json

Alternatively, you can use:

JSON.generate({:make => "bmw", :year => "2003"})

You can make an Embedded class, which contains your two keys, and then have a reference to that class as EmbeddedId in your Entity.

You would need the @EmbeddedId and @Embeddable annotations.

@Entity
public class YourEntity {
    @EmbeddedId
    private MyKey myKey;

    @Column(name = "ColumnA")
    private String columnA;

    /** Your getters and setters **/
}

@Embeddable
public class MyKey implements Serializable {

    @Column(name = "Id", nullable = false)
    private int id;

    @Column(name = "Version", nullable = false)
    private int version;

    /** getters and setters **/
}

Another way to achieve this task is to use @IdClass annotation, and place both your id in that IdClass. Now you can use normal @Id annotation on both the attributes

@Entity
@IdClass(MyKey.class)
public class YourEntity {
   @Id
   private int id;
   @Id
   private int version;

}

public class MyKey implements Serializable {
   private int id;
   private int version;
}

You can also use the cdata package, which uses the concept of (transformation) control table:

# data
wide <- read.table(text="Code Country        1950    1951    1952    1953    1954
AFG  Afghanistan    20,249  21,352  22,532  23,557  24,555
ALB  Albania        8,097   8,986   10,058  11,123  12,246", header=TRUE, check.names=FALSE)

library(cdata)
# build control table
drec <- data.frame(
    Year=as.character(1950:1954),
    Value=as.character(1950:1954),
    stringsAsFactors=FALSE
)
drec <- cdata::rowrecs_to_blocks_spec(drec, recordKeys=c("Code", "Country"))

# apply control table
cdata::layout_by(drec, wide)

I am currently exploring that package and find it quite accessible. It is designed for much more complicated transformations and includes the backtransformation. There is a tutorial available.

You can also use Chocolatey.

Having it installed, just run:

choco install make

When it finishes, it is installed and available in Git for Bash / MinGW.

If you get the IP address from a DHCP server, you can also set the server to send a DNS server. Or add the nameserver 8.8.8.8 into /etc/resolvconf/resolv.conf.d/base file. The information in this file is included in the resolver configuration file even when no interfaces are configured.

This simple snippet of code does what you want

GestureDetector gestureDetector = new GestureDetector(getContext(), new GestureDetector.SimpleOnGestureListener() {
            @Override
            public boolean onSingleTapConfirmed(MotionEvent e) {
                KeyboardUtil.hideKeyboard(getActivity());
                return true;
            }
        });
mScrollView.setOnTouchListener((v, e) -> gestureDetector.onTouchEvent(e));

My ES5 solution for the problem:

var wrap_text = (ctx, text, x, y, lineHeight, maxWidth, textAlign) => {
  if(!textAlign) textAlign = 'center'
  ctx.textAlign = textAlign
  var words = text.split(' ')
  var lines = []
  var sliceFrom = 0
  for(var i = 0; i < words.length; i++) {
    var chunk = words.slice(sliceFrom, i).join(' ')
    var last = i === words.length - 1
    var bigger = ctx.measureText(chunk).width > maxWidth
    if(bigger) {
      lines.push(words.slice(sliceFrom, i).join(' '))
      sliceFrom = i
    }
    if(last) {
      lines.push(words.slice(sliceFrom, words.length).join(' '))
      sliceFrom = i
    }
  }
  var offsetY = 0
  var offsetX = 0
  if(textAlign === 'center') offsetX = maxWidth / 2
  for(var i = 0; i < lines.length; i++) {
    ctx.fillText(lines[i], x + offsetX, y + offsetY)
    offsetY = offsetY + lineHeight
  }
}

More information on the issue is on my blog.

If you're trying to get the integers from the command line args, you'll need something like this:

public static void main(String[] args) {
    int[] nums = new int[args.length];
    for(int i = 0; i < args.length; i++) {
        try {
            nums[i] = Integer.parseInt(args[i]);
        }
        catch(NumberFormatException nfe) {
            System.err.println("Invalid argument");
        }
    }

    // averaging code here
}

As for the actual averaging code, others have suggested how you can tweak that (so I won't repeat what they've said).

Edit: actually it's probably better to just put it inside the above loop and not use the nums array at all

Change the names of your inputs:

<input name="xyz[]" value="Lorem" />
<input name="xyz[]" value="ipsum"  />
<input name="xyz[]" value="dolor" />
<input name="xyz[]" value="sit" />
<input name="xyz[]" value="amet" />

Then:

$_POST['xyz'][0] == 'Lorem'
$_POST['xyz'][4] == 'amet'

If so, that would make my life ten times easier, as I could send an indefinite amount of information through a form and get it processed by the server simply by looping through the array of items with the name "xyz".

Note that this is probably the wrong solution. Obviously, it depends on the data you are sending.

For await/async aiounittest there is a slightly different pattern:

https://aiounittest.readthedocs.io/en/latest/asynctestcase.html#aiounittest.AsyncTestCase

async def test_await_async_fail(self):
    with self.assertRaises(Exception) as e:
        await async_one()

Maybe this can help :)

# find like file listing for s3 files

With ES6 and later (ECMAScript 2015), you can get all properties like this:

let keys = Object.keys(myObject);

And if you wanna list out all values:

let values = Object.keys(myObject).map(key => myObject[key]);

The message means that both the packages have functions with the same names. In this particular case, the testthat and assertive packages contain five functions with the same name.

When two functions have the same name, which one gets called?

R will look through the search path to find functions, and will use the first one that it finds.

search()
 ##  [1] ".GlobalEnv"        "package:assertive" "package:testthat" 
 ##  [4] "tools:rstudio"     "package:stats"     "package:graphics" 
 ##  [7] "package:grDevices" "package:utils"     "package:datasets" 
 ## [10] "package:methods"   "Autoloads"         "package:base"

In this case, since assertive was loaded after testthat, it appears earlier in the search path, so the functions in that package will be used.

is_true
## function (x, .xname = get_name_in_parent(x)) 
## {
##     x <- coerce_to(x, "logical", .xname)
##     call_and_name(function(x) {
##         ok <- x & !is.na(x)
##         set_cause(ok, ifelse(is.na(x), "missing", "false"))
##     }, x)
## }
<bytecode: 0x0000000004fc9f10>
<environment: namespace:assertive.base>

The functions in testthat are not accessible in the usual way; that is, they have been masked.

What if I want to use one of the masked functions?

You can explicitly provide a package name when you call a function, using the double colon operator, ::. For example:

testthat::is_true
## function () 
## {
##     function(x) expect_true(x)
## }
## <environment: namespace:testthat>

How do I suppress the message?

If you know about the function name clash, and don't want to see it again, you can suppress the message by passing warn.conflicts = FALSE to library.

library(testthat)
library(assertive, warn.conflicts = FALSE)
# No output this time

Alternatively, suppress the message with suppressPackageStartupMessages:

library(testthat)
suppressPackageStartupMessages(library(assertive))
# Also no output

Impact of R's Startup Procedures on Function Masking

If you have altered some of R's startup configuration options (see ?Startup) you may experience different function masking behavior than you might expect. The precise order that things happen as laid out in ?Startup should solve most mysteries.

For example, the documentation there says:

Note that when the site and user profile files are sourced only the base package is loaded, so objects in other packages need to be referred to by e.g. utils::dump.frames or after explicitly loading the package concerned.

Which implies that when 3rd party packages are loaded via files like .Rprofile you may see functions from those packages masked by those in default packages like stats, rather than the reverse, if you loaded the 3rd party package after R's startup procedure is complete.

How do I list all the masked functions?

First, get a character vector of all the environments on the search path. For convenience, we'll name each element of this vector with its own value.

library(dplyr)
envs <- search() %>% setNames(., .)

For each environment, get the exported functions (and other variables).

fns <- lapply(envs, ls)

Turn this into a data frame, for easy use with dplyr.

fns_by_env <- data_frame(
  env = rep.int(names(fns), lengths(fns)),
  fn  = unlist(fns)
)

Find cases where the object appears more than once.

fns_by_env %>% 
  group_by(fn) %>% 
  tally() %>% 
  filter(n > 1) %>% 
  inner_join(fns_by_env)

To test this, try loading some packages with known conflicts (e.g., Hmisc, AnnotationDbi).

How do I prevent name conflict bugs?

The conflicted package throws an error with a helpful error message, whenever you try to use a variable with an ambiguous name.

library(conflicted)
library(Hmisc)
units
## Error: units found in 2 packages. You must indicate which one you want with ::
##  * Hmisc::units
##  * base::units

Short answer in bolds:

• collect is mainly to serialize
  (loss of parallelism preserving all other data characteristics of the dataframe)
  For example with a PrintWriter pw you can't do direct df.foreach( r => pw.write(r) ), must to use collect before foreach, df.collect.foreach(etc).
  PS: the "loss of parallelism" is not a "total loss" because after serialization it can be distributed again to executors.

• select is mainly to select columns, similar to projection in relational algebra
  (only similar in framework's context because Spark select not deduplicate data).
  So, it is also a complement of filter in the framework's context.

Commenting explanations of other answers: I like the Jeff's classification of Spark operations in transformations (as select) and actions (as collect). It is also good remember that transforms (including select) are lazily evaluated.

In case someone else ends up here struggling to customize admin form Many2Many saving behaviour, you can't call self.instance.my_m2m.add(obj) in your ModelForm.save override, as ModelForm.save later populates your m2m from self.cleaned_data['my_m2m'] which overwrites your changes. Instead call:

my_m2ms = list(self.cleaned_data['my_m2ms'])
my_m2ms.extend(my_custom_new_m2ms)
self.cleaned_data['my_m2ms'] = my_m2ms

(It is fine to convert the incoming QuerySet to a list - the ManyToManyField does that anyway.)

Here is a tested code for image and video.It will work for all APIs less than 19 and greater than 19 as well.

Borrowing from @Khan's answer, I would do:

IF OBJECT_ID('dbo.test_abc_def', 'V') IS NOT NULL
    DROP VIEW dbo.test_abc_def
GO

CREATE VIEW dbo.test_abc_def AS
SELECT 
    VCV.xxxx
    ,VCV.yyyy AS yyyy
    ,VCV.zzzz AS zzzz
FROM TABLE_A

With help from numpy one can calculate for example a linear fitting.

# plot the data itself
pylab.plot(x,y,'o')

# calc the trendline
z = numpy.polyfit(x, y, 1)
p = numpy.poly1d(z)
pylab.plot(x,p(x),"r--")
# the line equation:
print "y=%.6fx+(%.6f)"%(z[0],z[1])

Might just be for Visual Studio '15, if you right-click on source code, there's an option for insert comment

This puts summary tags around your comment section, but it does give the indentation that you want.

No, a view is queried no differently to SELECTing from a table.

To do what you want, use a table-valued user-defined function with one or more parameters

I did not have 1.5 available to me, because I am not in control of the computer. The file that was causing me a problem happened to be a .jar file in the lib directory. Here is what I did to solve the problem:

rm -rf lib
svn up

This builds on Ned's answer. That is: I just removed the sub directory that was causing me a problem rather than the entire repository.

This worked for me,

$recipient_email = '[email protected],[email protected]';

$success = mail($recipient_email, $subject, $body, $headers);

            int rawContactInsertIndex = ops.size();

                    .withValue(RawContacts.ACCOUNT_TYPE, null)
                    .withValue(RawContacts.ACCOUNT_NAME, null).build());
            ops.add(ContentProviderOperation
                    .newInsert(Data.CONTENT_URI)
                    .withValueBackReference(Data.RAW_CONTACT_ID,rawContactInsertIndex)

When you say

val map = scala.collection.mutable.Map

you are not creating a map instance, but instead aliasing the Map type.

map: collection.mutable.Map.type = scala.collection.mutable.Map$@fae93e

Try instead the following:

scala> val map = scala.collection.mutable.Map[String, Int]()
map: scala.collection.mutable.Map[String,Int] = Map()

scala> map("asdf") = 9

scala> map
res6: scala.collection.mutable.Map[String,Int] = Map((asdf,9))

None of the above worked for me in Sublime Text 2 on Windows.

I did this:

• click on an empty line;
• drag to the following empty line (selecting the invisible character after the line);
• press ctrl+H for replace;
• input desired replacement character/string or leave it empty;
• click "Replace all";

By selecting before hitting ctrl+H it uses that as the character to be replaced.

Nothing new here but married this answer with this answer and slightly refactored it so that even I understand what's going on:

public static class ExpressionExtensions
{
    public static Expression<Func<T, bool>> AndAlso<T>(this Expression<Func<T, bool>> expr1, Expression<Func<T, bool>> expr2)
    {
        ParameterExpression parameter1 = expr1.Parameters[0];
        var visitor = new ReplaceParameterVisitor(expr2.Parameters[0], parameter1);
        var body2WithParam1 = visitor.Visit(expr2.Body);
        return Expression.Lambda<Func<T, bool>>(Expression.AndAlso(expr1.Body, body2WithParam1), parameter1);
    }

    private class ReplaceParameterVisitor : ExpressionVisitor
    {
        private ParameterExpression _oldParameter;
        private ParameterExpression _newParameter;

        public ReplaceParameterVisitor(ParameterExpression oldParameter, ParameterExpression newParameter)
        {
            _oldParameter = oldParameter;
            _newParameter = newParameter;
        }

        protected override Expression VisitParameter(ParameterExpression node)
        {
            if (ReferenceEquals(node, _oldParameter))
                return _newParameter;

            return base.VisitParameter(node);
        }
    }
}

I would suggest instead of creating a new table, you just use a view that combines the two tables, this way if any of the data in table 1 or table 2 changes, you don't need to update the third table:

CREATE VIEW dbo.YourView
AS
    SELECT  t1.Name, t1.Age, t1.Sex, t1.City, t1.ID, t2.Number
    FROM    Table1 t1
            INNER JOIN Table2 t2
                ON t1.ID = t2.ID;

If you could have records in one table, and not in the other, then you would need to use a full join:

CREATE VIEW dbo.YourView
AS
    SELECT  t1.Name, t1.Age, t1.Sex, t1.City, ID = ISNULL(t1.ID, t2.ID), t2.Number
    FROM    Table1 t1
            FULL JOIN Table2 t2
                ON t1.ID = t2.ID;

If you know all records will be in table 1 and only some in table 2, then you should use a LEFT JOIN:

CREATE VIEW dbo.YourView
AS
    SELECT  t1.Name, t1.Age, t1.Sex, t1.City, t1.ID, t2.Number
    FROM    Table1 t1
            LEFT JOIN Table2 t2
                ON t1.ID = t2.ID;

If you know all records will be in table 2 and only some in table 2 then you could use a RIGHT JOIN

CREATE VIEW dbo.YourView
AS
    SELECT  t1.Name, t1.Age, t1.Sex, t1.City, t2.ID, t2.Number
    FROM    Table1 t1
            RIGHT JOIN Table2 t2
                ON t1.ID = t2.ID;

Or just reverse the order of the tables and use a LEFT JOIN (I find this more logical than a right join but it is personal preference):

CREATE VIEW dbo.YourView
AS
    SELECT  t1.Name, t1.Age, t1.Sex, t1.City, t2.ID, t2.Number
    FROM    Table2 t2
            LEFT JOIN Table1 t1
                ON t1.ID = t2.ID;

In addition to what John Skeet said, here's an overview of the Java 7 project. It includes a list and description of the features.

Note: JDK 7 was released on July 28, 2011, so you should now go to the official java SE site.

You may also set {{ant.build.javac.target=1.5}} ant property to update default target version of task. See http://ant.apache.org/manual/javacprops.html#target

Short answer: You can't. rm removes files blindly, with no concept of 'trash'.

Some Unix and Linux systems try to limit its destructive ability by aliasing it to rm -i by default, but not all do.

Long answer: Depending on your filesystem, disk activity, and how long ago the deletion occured, you may be able to recover some or all of what you deleted. If you're using an EXT3 or EXT4 formatted drive, you can check out extundelete.

In the future, use rm with caution. Either create a del alias that provides interactivity, or use a file manager.

In my practice I personally settled down with one simple rule - Use references for primitives and values that are copyable/movable and pointers for objects with long life cycle.

For Node example I would definitely use

AddChild(Node* pNode);

Be careful to check if

display_errors

or

error_reporting

is active (not a comment) somewhere else in the ini file.

My development server refused to display errors after upgrade to Kubuntu 16.04 - I had checked php.ini numerous times ... turned out that there was a diplay_errors = off; about 100 lines below my

display_errors = on;

So remember the last one counts!

This is expected. Refer to Javadocs for split.

Splits this string around matches of the given regular expression.

This method works as if by invoking the two-argument split(java.lang.String,int) method with the given expression and a limit argument of zero. Trailing empty strings are therefore not included in the resulting array.

I think you can use CHECK constraint - it is exactly what it was invented for.

ALTER TABLE someTable 
ADD CONSTRAINT someField_check CHECK (ISNUMERIC(someField) = 1) ;

My previous answer (also right by may be a bit overkill):

I think the right way is to use INSTEAD OF trigger to prevent the wrong data from being inserted (rather than deleting it post-factum)

What you are trying to do is impossible; your current shell is running under your regular user ID (i.e. without root the access sudo would give you), and there is no way to grant it root access. What sudo does is create a new *sub*process that runs as root. The subprocess could be just a regular program (e.g. sudo cp ... runs the cp program in a root process) or it could be a root subshell, but it cannot be the current shell.

(It's actually even more impossible than that, because the sudo command itself is executed as a subprocess of the current shell -- meaning that in a sense it's already too late for it to do anything in the "current shell", because that's not where it executes.)

To write a newline use \n not /n the latter is just a slash and a n

envsubst seems exactly like something I wanted to use, but -v option surprised me a bit.

While envsubst < template.txt was working fine, the same with option -v was not working:

$ cat /etc/redhat-release
Red Hat Enterprise Linux Server release 7.1 (Maipo)
$ envsubst -V

As I wrote, this was not working:

$ envsubst -v < template.txt
envsubst: missing arguments
$ cat template.txt | envsubst -v
envsubst: missing arguments

I had to do this to make it work:

TEXT=`cat template.txt`; envsubst -v "$TEXT"

Maybe it helps someone.

(at least) for Django 1.8:

If you use

if settings.DEBUG:
  urlpatterns.append(url(r'^media/(?P<path>.*)$', 'django.views.static.serve', {'document_root': settings.MEDIA_ROOT}))

as described above, make sure that no "catch all" url pattern, directing to a default view, comes before that in urlpatterns = []. As .append will put the added scheme to the end of the list, it will of course only be tested if no previous url pattern matches. You can avoid that by using something like this where the "catch all" url pattern is added at the very end, independent from the if statement:

if settings.DEBUG:
    urlpatterns.append(url(r'^media/(?P<path>.*)$', 'django.views.static.serve', {'document_root': settings.MEDIA_ROOT}))

urlpatterns.append(url(r'$', 'views.home', name='home')),

I had a problem with the white screen after installing a new laravel instance. I couldn't find anything in the logs because (eventually I found out) that the reason for the white screen was that app/storage wasn't writable.

In order to get an error message on the screen I added the following to the public/index.php

try {
    $app->run();
} catch(\Exception $e) {
    echo "<pre>";
    echo $e;
    echo "</pre>";
}

After that it was easy to solve the problem.

Using LINQ to xml if you are using framework 3.5

using System.Xml.Linq;

XDocument xmlFile = XDocument.Load("books.xml"); 
var query = from c in xmlFile.Elements("catalog").Elements("book")    
            select c; 
foreach (XElement book in query) 
{
    book.Attribute("attr1").Value = "MyNewValue";
}
xmlFile.Save("books.xml");

Nowadays you can get correct timezone of a user having just one line of code:

const timezone = Intl.DateTimeFormat().resolvedOptions().timeZone;

source: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/DateTimeFormat/resolvedOptions

You can then use moment-timezone to parse timezone like:

const currentTime = moment().tz(timezone).format();

The current (as of version 0.20) method for changing column names after a groupby operation is to chain the rename method. See this deprecation note in the documentation for more detail.

Deprecated Answer as of pandas version 0.20

This is the first result in google and although the top answer works it does not really answer the question. There is a better answer here and a long discussion on github about the full functionality of passing dictionaries to the agg method.

These answers unfortunately do not exist in the documentation but the general format for grouping, aggregating and then renaming columns uses a dictionary of dictionaries. The keys to the outer dictionary are column names that are to be aggregated. The inner dictionaries have keys that the new column names with values as the aggregating function.

Before we get there, let's create a four column DataFrame.

df = pd.DataFrame({'A' : list('wwwwxxxx'), 
                   'B':list('yyzzyyzz'), 
                   'C':np.random.rand(8), 
                   'D':np.random.rand(8)})

   A  B         C         D
0  w  y  0.643784  0.828486
1  w  y  0.308682  0.994078
2  w  z  0.518000  0.725663
3  w  z  0.486656  0.259547
4  x  y  0.089913  0.238452
5  x  y  0.688177  0.753107
6  x  z  0.955035  0.462677
7  x  z  0.892066  0.368850

Let's say we want to group by columns A, B and aggregate column C with mean and median and aggregate column D with max. The following code would do this.

df.groupby(['A', 'B']).agg({'C':['mean', 'median'], 'D':'max'})

            D         C          
          max      mean    median
A B                              
w y  0.994078  0.476233  0.476233
  z  0.725663  0.502328  0.502328
x y  0.753107  0.389045  0.389045
  z  0.462677  0.923551  0.923551

This returns a DataFrame with a hierarchical index. The original question asked about renaming the columns in the same step. This is possible using a dictionary of dictionaries:

df.groupby(['A', 'B']).agg({'C':{'C_mean': 'mean', 'C_median': 'median'}, 
                            'D':{'D_max': 'max'}})

            D         C          
        D_max    C_mean  C_median
A B                              
w y  0.994078  0.476233  0.476233
  z  0.725663  0.502328  0.502328
x y  0.753107  0.389045  0.389045
  z  0.462677  0.923551  0.923551

This renames the columns all in one go but still leaves the hierarchical index which the top level can be dropped with df.columns = df.columns.droplevel(0).

Every ComboBoxItem instance has PreviewMouseDown event. If you will subscribe your custom handler on this event on every ComboBoxItem you will have opportunity to handle every click on the dropdown list.

// Subscribe on ComboBoxItem-s events.
comboBox.Items.Cast<ComboBoxItem>().ToList().ForEach(i => i.PreviewMouseDown += ComboBoxItem_PreviewMouseDown);

private void ComboBoxItem_PreviewMouseDown(object sender, MouseButtonEventArgs e)
{
     // your handler logic...         
}

Classes (or rather their instances) are for representing things. Classes are used to define the operations supported by a particular class of objects (its instances). If your application needs to keep track of people, then Person is probably a class; the instances of this class represent particular people you are tracking.

Functions are for calculating things. They receive inputs and produce an output and/or have effects.

Classes and functions aren't really alternatives, as they're not for the same things. It doesn't really make sense to consider making a class to "calculate the age of a person given his/her birthday year and the current year". You may or may not have classes to represent any of the concepts of Person, Age, Year, and/or Birthday. But even if Age is a class, it shouldn't be thought of as calculating a person's age; rather the calculation of a person's age results in an instance of the Age class.

If you are modelling people in your application and you have a Person class, it may make sense to make the age calculation be a method of the Person class. A method is basically a function which is defined as part of a class; this is how you "define the operations supported by a particular class of objects" as I mentioned earlier.

So you could create a method on your person class for calculating the age of the person (it would probably retrieve the birthday year from the person object and receive the current year as a parameter). But the calculation is still done by a function (just a function that happens to be a method on a class).

Or you could simply create a stand-alone function that receives arguments (either a person object from which to retrieve a birth year, or simply the birth year itself). As you note, this is much simpler if you don't already have a class where this method naturally belongs! You should never create a class simply to hold an operation; if that's all there is to the class then the operation should just be a stand-alone function.

You will need to drop and re-create the primary key like this:

alter table my_table drop constraint my_pk;
alter table my_table add constraint my_pk primary key (city_id, buildtime, time);

However, if there are other tables with foreign keys that reference this primary key, then you will need to drop those first, do the above, and then re-create the foreign keys with the new column list.

An alternative syntax to drop the existing primary key (e.g. if you don't know the constraint name):

alter table my_table drop primary key;

Here's a (probably too) simple option:

sed "s/,/\t/g" filename.csv | less

If you're running Charles and trying to build a docker container then you'll most likely get this error.

Make sure to disable Charles (macos) proxy under proxy -> macOS proxy

Charles is an

HTTP proxy / HTTP monitor / Reverse Proxy that enables a developer to view all of the HTTP and SSL / HTTPS traffic between their machine and the Internet.

So anything similar may cause the same issue.

not exactly, but you may be able to accomplish what you need by invoking Collectors.groupingBy(). you create a new Collection, and can then instantiate streams on that new collection.

This provides you the code example on sorting map. Basically this is what they provide:

var keys []int
for k := range myMap {
    keys = append(keys, k)
}
sort.Ints(keys)

// Benchmark1-8      2863149           374 ns/op         152 B/op          5 allocs/op

and this is what I would suggest using instead:

keys := make([]int, 0, len(myMap))
for k := range myMap {
    keys = append(keys, k)
}
sort.Ints(keys)

// Benchmark2-8      5320446           230 ns/op          80 B/op          2 allocs/op

this is valid string is eg"123". in your case split by space..

split(" "); will split line by " " by space..

In mathematics, there are sets and ordered sets (osets).

• set: an unordered container of unique elements (Implemented)
• oset: an ordered container of unique elements (NotImplemented)

In Python, only sets are directly implemented. We can emulate osets with regular dict keys (3.7+).

Given

a = [1, 2, 20, 6, 210, 2, 1]
b = {2, 6}

Code

oset = dict.fromkeys(a).keys()
# dict_keys([1, 2, 20, 6, 210])

Demo

Replicates are removed, insertion-order is preserved.

list(oset)
# [1, 2, 20, 6, 210]

Set-like operations on dict keys.

oset - b
# {1, 20, 210}

oset | b
# {1, 2, 5, 6, 20, 210}

oset & b
# {2, 6}

oset ^ b
# {1, 5, 20, 210}

Details

Note: an unordered structure does not preclude ordered elements. Rather, maintained order is not guaranteed. Example:

assert {1, 2, 3} == {2, 3, 1}                    # sets (order is ignored)

assert [1, 2, 3] != [2, 3, 1]                    # lists (order is guaranteed)

One may be pleased to discover that a list and multiset (mset) are two more fascinating, mathematical data structures:

• list: an ordered container of elements that permits replicates (Implemented)
• mset: an unordered container of elements that permits replicates (NotImplemented)*

Summary

Container | Ordered | Unique | Implemented
----------|---------|--------|------------
set       |    n    |    y   |     y
oset      |    y    |    y   |     n
list      |    y    |    n   |     y
mset      |    n    |    n   |     n*  

^{*A multiset can be indirectly emulated with collections.Counter(), a dict-like mapping of multiplicities (counts).}

To create a "drop down menu" you can use OptionMenu in tkinter

Example of a basic OptionMenu:

from Tkinter import *

master = Tk()

variable = StringVar(master)
variable.set("one") # default value

w = OptionMenu(master, variable, "one", "two", "three")
w.pack()

mainloop()

More information (including the script above) can be found here.

Creating an OptionMenu of the months from a list would be as simple as:

from tkinter import *

OPTIONS = [
"Jan",
"Feb",
"Mar"
] #etc

master = Tk()

variable = StringVar(master)
variable.set(OPTIONS[0]) # default value

w = OptionMenu(master, variable, *OPTIONS)
w.pack()

mainloop()

In order to retrieve the value the user has selected you can simply use a .get() on the variable that we assigned to the widget, in the below case this is variable:

from tkinter import *

OPTIONS = [
"Jan",
"Feb",
"Mar"
] #etc

master = Tk()

variable = StringVar(master)
variable.set(OPTIONS[0]) # default value

w = OptionMenu(master, variable, *OPTIONS)
w.pack()

def ok():
    print ("value is:" + variable.get())

button = Button(master, text="OK", command=ok)
button.pack()

mainloop()

I would highly recommend reading through this site for further basic tkinter information as the above examples are modified from that site.

From Using Triggers:

Detecting the DML Operation That Fired a Trigger

If more than one type of DML operation can fire a trigger (for example, ON INSERT OR DELETE OR UPDATE OF Emp_tab), the trigger body can use the conditional predicates INSERTING, DELETING, and UPDATING to check which type of statement fire the trigger.

So

IF DELETING THEN ... END IF;

should work for your case.

If anyone is strugling with the same problem I solved it by adding @EntityScan in my main class. Just add your model package to the basePackages property.

Seen a lot of the answers, but the correct one is to provide the full options for the header function call as per the php manual

void header ( string $string [, bool $replace = true [, int $http_response_code ]] )

If you invoke with

header('HTTP/1.0 403 Forbidden', true, 403);

the normal behavior of HTTP 403 as configured with Apache or any other server would follow.

You would need to use a reinterpret_cast<> as the two types you are casting between are unrelated to each other.

From the doc.

The webbrowser module provides a high-level interface to allow displaying Web-based documents to users. Under most circumstances, simply calling the open() function from this module will do the right thing.

You have to import the module and use open() function. This will open https://nabinkhadka.com.np in the browser.

To open in new tab:

import webbrowser
webbrowser.open('https://nabinkhadka.com.np', new = 2)

Also from the doc.

If new is 0, the url is opened in the same browser window if possible. If new is 1, a new browser window is opened if possible. If new is 2, a new browser page (“tab”) is opened if possible

So according to the value of new, you can either open page in same browser window or in new tab etc.

Also you can specify as which browser (chrome, firebox, etc.) to open. Use get() function for this.

I would use this query:

SELECT
  user_id
FROM
  wp_usermeta 
WHERE 
  (meta_key = 'first_name' AND meta_value = '$us_name') OR 
  (meta_key = 'yearofpassing' AND meta_value = '$us_yearselect') OR 
  (meta_key = 'u_city' AND meta_value = '$us_reg') OR
  (meta_key = 'us_course' AND meta_value = '$us_course')
GROUP BY
  user_id
HAVING
  COUNT(DISTINCT meta_key)=4

this will select all user_id that meets all four conditions.

It is very easy to achieve with built in method SelectAll

Simply cou can write this:

txtTextBox.Focus();
txtTextBox.SelectAll();

And everything in textBox will be selected :)

Using text/csv is the most appropriate type.

You should also consider adding a Content-Disposition header to the response. Often a text/csv will be loaded by a Internet Explorer directly into a hosted instance of Excel. This may or may not be a desirable result.

Response.AddHeader("Content-Disposition", "attachment;filename=myfilename.csv");

The above will cause a file "Save as" dialog to appear which may be what you intend.

In AIX you can try:
