Here comes the long-winded – yet easy to understand – script, inspired by the solution of nicerobot, that only requests the response headers and avoids using IFS as suggested here. It outputs a bounce message when it encounters a response >= 400. This echo can be replaced with a bounce-script.

# set the url to probe
url='http://localhost:8080'
# use curl to request headers (return sensitive default on timeout: "timeout 500"). Parse the result into an array (avoid settings IFS, instead use read)
read -ra result <<< $(curl -Is --connect-timeout 5 "${url}" || echo "timeout 500")
# status code is second element of array "result"
status=${result[1]}
# if status code is greater than or equal to 400, then output a bounce message (replace this with any bounce script you like)
[ $status -ge 400  ] && echo "bounce at $url with status $status"

It could be done by getting the page title by Selenium and do assertion by using TestNG.

1. Import Assert class in the import section:

   `import org.testng.Assert;`
   

2. Create a WebDriver object:

   WebDriver driver=new FirefoxDriver();

3. Apply this to assert the title of the page:

   Assert.assertEquals("Expected page title", driver.getTitle());

Although returning a pointer to a local object is bad practice, it didn't cause the kaboom here. Here's why you got a segfault:

int *fun()
{
    int *point;
    *point=12;  <<<<<<  your program crashed here.
    return point;
}

The local pointer goes out of scope, but the real issue is dereferencing a pointer that was never initialized. What is the value of point? Who knows. If the value did not map to a valid memory location, you will get a SEGFAULT. If by luck it mapped to something valid, then you just corrupted memory by overwriting that place with your assignment to 12.

Since the pointer returned was immediately used, in this case you could get away with returning a local pointer. However, it is bad practice because if that pointer was reused after another function call reused that memory in the stack, the behavior of the program would be undefined.

int *fun()
{
    int point;
    point = 12;
    return (&point);
}

or almost identically:

int *fun()
{
    int point;
    int *point_ptr;
    point_ptr = &point;
    *point_ptr = 12;
    return (point_ptr);
}

Another bad practice but safer method would be to declare the integer value as a static variable, and it would then not be on the stack and would be safe from being used by another function:

int *fun()
{
    static int point;
    int *point_ptr;
    point_ptr = &point;
    *point_ptr = 12;
    return (point_ptr);
}

or

int *fun()
{
    static int point;
    point = 12;
    return (&point);
}

As others have mentioned, the "right" way to do this would be to allocate memory on the heap, via malloc.

xml:space="preserve" has to work for all compliant XML parsers.

However, note that in HTML the line break is just whitespace and NOT a line break (this is represented with the <br /> (X)HTML tag, maybe this is the problem which you are facing.

You can also add 
 and/or 
 to insert CR/LF characters.

The correct fix is to add the property in the type definition as explained in @Nitzan Tomer's answer. If that's not an option though:

(Hacky) Workaround 1

You can assign the object to a constant of type any, then call the 'non-existing' property.

const newObj: any = oldObj;
return newObj.someProperty;

You can also cast it as any:

return (oldObj as any).someProperty;

This fails to provide any type safety though, which is the point of TypeScript.

(Hacky) Workaround 2

Another thing you may consider, if you're unable to modify the original type, is extending the type like so:

interface NewType extends OldType {
  someProperty: string;
}

Now you can cast your variable as this NewType instead of any. Still not ideal but less permissive than any, giving you more type safety.

return (oldObj as NewType).someProperty;

I don't know if this was true at the time of the original posting, but the siblings method allows selectors, so a reduction of what the OP listed should work.

 $(this).siblings(':not(.closedTab)');

At least at STS (SpringSource Tool Suite) groups are numbered starting form 0, so replace string will be

replace: ((TypeName)$0)

Using .apply() with a lambda conversion function also works in this case:

total_rows['ColumnID'] = total_rows['ColumnID'].apply(lambda x: str(x))

For entire dataframes you can use .applymap(). (but in any case probably .astype() is faster)

Hi we can use ToLower Method sometimes it is not filter.

EmployeeId = Session["EmployeeID"].ToString();
var rows = dtCrewList.AsEnumerable().Where
   (row => row.Field<string>("EmployeeId").ToLower()== EmployeeId.ToLower());

   if (rows.Any())
   {
        tblFiltered = rows.CopyToDataTable<DataRow>();
   }

This python3 example uses a recursive solution:

# Hanoi towers puzzle
# for each n, you have to move n-1 disks off the n disk onto another peg
# then you move the n disk to a free peg
# then you move the n-1 disks on the other peg back onto the n disk

def hanoi(n):
    if n == 1:
        return 1
    else:
        return hanoi(n-1) + 1 + hanoi(n-1)


for i in range(1, 11):
    print(f"n={i}, moves={hanoi(i)}")

Output:

n=1, moves=1
n=2, moves=3
n=3, moves=7
n=4, moves=15
n=5, moves=31
n=6, moves=63
n=7, moves=127
n=8, moves=255
n=9, moves=511
n=10, moves=1023

But of course the most efficient way to work out how many moves is to realise that the answers are always 1 less than 2^n. So the mathematical solution is 2^n - 1

I think you could do it using a specs file.

Under MinGW you could run
gcc -dumpspecs > specs

Where it says

*cpp:
%{posix:-D_POSIX_SOURCE} %{mthreads:-D_MT}

You change it to

*cpp:
%{posix:-D_POSIX_SOURCE} %{mthreads:-D_MT} -std=c++11

And then place it in
/mingw/lib/gcc/mingw32/<version>/specs

I'm sure you could do the same without a MinGW build. Not sure where to place the specs file though.

The folder is probably either /gcc/lib/ or /gcc/.

FYI

The method call System.runFinalizersOnExit(true) guarantees that finalizer methods are called before Java shuts down. However, this method is inherently unsafe and has been deprecated. An alternative is to add “shutdown hooks” with the method Runtime.addShutdownHook.

On some system may be useful to use this constant because if, for example, you are sending an email, you can use PHP_EOL to have a cross-system script working on more systems... but even if it's useful sometime you can find this constant undefined, modern hosting with latest php engine do not have this problem but I think that a good thing is write a bit code that saves this situation:

<?php
  if (!defined('PHP_EOL')) {
    if (strtoupper(substr(PHP_OS,0,3) == 'WIN')) {
      define('PHP_EOL',"\r\n");
    } elseif (strtoupper(substr(PHP_OS,0,3) == 'MAC')) {
      define('PHP_EOL',"\r");
    } elseif (strtoupper(substr(PHP_OS,0,3) == 'DAR')) {
      define('PHP_EOL',"\n");
    } else {
      define('PHP_EOL',"\n");
    }
  }
?>

So you can use PHP_EOL without problems... obvious that PHP_EOL should be used on script that should work on more systems at once otherwise you can use \n or \r or \r\n...

Note: PHP_EOL can be

1) on Unix    LN    == \n
2) on Mac     CR    == \r
3) on Windows CR+LN == \r\n

Hope this answer help.

For Windows 8 client computers, turn on "IIS-ASPNET45" in "Turn Windows Features On/Off" under "Internet Information Services-> World Wide Web Services -> Application Development Features -> ASP.NET 4.5".

A couple of different ways to solve the problem:

Just replace Environment.Exit with return. The compiler knows that return ends the method, but doesn't know that Environment.Exit does.

static void Main(string[] args) {
    if(args.Length != 0) {
       if(Byte.TryParse(args[0], out maxSize))
         queue = new Queue(){MaxSize = maxSize};
       else
         return;
    } else {
       return;   
}

Of course, you can really only get away with that because you're using 0 as your exit code in all cases. Really, you should return an int instead of using Environment.Exit. For this particular case, this would be my preferred method

static int Main(string[] args) {
    if(args.Length != 0) {
       if(Byte.TryParse(args[0], out maxSize))
         queue = new Queue(){MaxSize = maxSize};
       else
         return 1;
    } else {
       return 2;
    }
}

Initialize queue to null, which is really just a compiler trick that says "I'll figure out my own uninitialized variables, thank you very much". It's a useful trick, but I don't like it in this case - you have too many if branches to easily check that you're doing it properly. If you really wanted to do it this way, something like this would be clearer:

static void Main(string[] args) {
  Byte maxSize;
  Queue queue = null;

  if(args.Length == 0 || !Byte.TryParse(args[0], out maxSize)) {
     Environment.Exit(0);
  }
  queue = new Queue(){MaxSize = maxSize};

  for(Byte j = 0; j < queue.MaxSize; j++)
    queue.Insert(j);
  for(Byte j = 0; j < queue.MaxSize; j++)
    Console.WriteLine(queue.Remove());
}

Add a return statement after Environment.Exit. Again, this is more of a compiler trick - but is slightly more legit IMO because it adds semantics for humans as well (though it'll keep you from that vaunted 100% code coverage)

static void Main(String[] args) {
  if(args.Length != 0) {
     if(Byte.TryParse(args[0], out maxSize)) {
        queue = new Queue(){MaxSize = maxSize};
     } else {
        Environment.Exit(0);
        return;
     }
  } else { 
     Environment.Exit(0);
     return;
  }

  for(Byte j = 0; j < queue.MaxSize; j++)
     queue.Insert(j);
  for(Byte j = 0; j < queue.MaxSize; j++)
     Console.WriteLine(queue.Remove());
}

First of all, your description is misleading. Double is a floating point data type. You presumably want to pad your digits with leading zeros in a string. The following code does that:

$s = sprintf('%02d', $digit);

For more information, refer to the documentation of sprintf.

Okay, here is a solution to reduce the physical size of the transaction file, but without changing the recovery mode to simple.

Within your database, locate the file_id of the log file using the following query.

SELECT * FROM sys.database_files;

In my instance, the log file is file_id 2. Now we want to locate the virtual logs in use, and do this with the following command.

DBCC LOGINFO;

Here you can see if any virtual logs are in use by seeing if the status is 2 (in use), or 0 (free). When shrinking files, empty virtual logs are physically removed starting at the end of the file until it hits the first used status. This is why shrinking a transaction log file sometimes shrinks it part way but does not remove all free virtual logs.

If you notice a status 2's that occur after 0's, this is blocking the shrink from fully shrinking the file. To get around this do another transaction log backup, and immediately run these commands, supplying the file_id found above, and the size you would like your log file to be reduced to.

-- DBCC SHRINKFILE (file_id, LogSize_MB)
DBCC SHRINKFILE (2, 100);
DBCC LOGINFO;

This will then show the virtual log file allocation, and hopefully you'll notice that it's been reduced somewhat. Because virtual log files are not always allocated in order, you may have to backup the transaction log a couple of times and run this last query again; but I can normally shrink it down within a backup or two.

Good question. I'm using the Bootstrap Dropdown Menu, and needed to execute an event when a Bootstrap Dropdown was hidden. When the dropdown is opened, the containing div with a class name of "button-group" adds a class of "open"; and the button itself has an "aria-expanded" attribute set to true. When the dropdown is closed, that class of "open" is removed from the containing div, and aria-expanded is switched from true to false.

That led me to this question, of how to detect the class change.

With Bootstrap, there are "Dropdown Events" that can be detected. Look for "Dropdown Events" at this link. http://www.w3schools.com/bootstrap/bootstrap_ref_js_dropdown.asp

Here is a quick-and-dirty example of using this event on a Bootstrap Dropdown.

$(document).on('hidden.bs.dropdown', function(event) {
    console.log('closed');
});

Now I realize this is more specific than the general question that's being asked. But I imagine other developers trying to detect an open or closed event with a Bootstrap Dropdown will find this helpful. Like me, they may initially go down the path of simply trying to detect an element class change (which apparently isn't so simple). Thanks.

In any method use the below condition

You can have something like this

            File.WriteAllBytes(fileName, ASCIIEncoding.Convert(ASCIIEncoding.ASCII, new UTF8Encoding(true), convertToCSV(result, fileName)));
            break;
        case "ISO-8859-1":
            File.WriteAllBytes(fileName, ASCIIEncoding.Convert(ASCIIEncoding.ASCII, Encoding.GetEncoding("iso-8859-1"), convertToCSV(result, fileName)));
            break;
        case ..............
    }

Mongoose 4.4 added a method called insertMany

Shortcut for validating an array of documents and inserting them into MongoDB if they're all valid. This function is faster than .create() because it only sends one operation to the server, rather than one for each document.

Quoting vkarpov15 from issue #723:

The tradeoffs are that insertMany() doesn't trigger pre-save hooks, but it should have better performance because it only makes 1 round-trip to the database rather than 1 for each document.

The method's signature is identical to create:

Model.insertMany([ ... ], (err, docs) => {
  ...
})

Or, with promises:

Model.insertMany([ ... ]).then((docs) => {
  ...
}).catch((err) => {
  ...
})

As @Ian explained, the problem is that jQuery's click() is not the same as the native one.

Therefore, consider using vanilla-js instead of jQuery:

var a = document.createElement('a');
a.href = "img.png";
a.download = "output.png";
document.body.appendChild(a);
a.click();
document.body.removeChild(a);

Demo

Please try set TabStop to False for your view control which is not be focused.

For eg:

txtEmpID.TabStop = false;

If the project is a GUI project, no console will appear. In order to change the project into a console one you need to go to the project properties panel and set:

• In "linker->System->SubSystem" the value "Console (/SUBSYSTEM:CONSOLE)"
• In "C/C++->Preprocessor->Preprocessor Definitions" add the "_CONSOLE" define

This solution works only if you had the classic "int main()" entry point.

But if you are like in my case (an openGL project), you don't need to edit the properties, as this works better:

AllocConsole();
freopen("CONIN$", "r",stdin);
freopen("CONOUT$", "w",stdout);
freopen("CONOUT$", "w",stderr);

printf and cout will work as usual.

If you call AllocConsole before the creation of a window, the console will appear behind the window, if you call it after, it will appear ahead.

Update

freopen is deprecated and may be unsafe. Use freopen_s instead:

FILE* fp;

AllocConsole();
freopen_s(&fp, "CONIN$", "r", stdin);
freopen_s(&fp, "CONOUT$", "w", stdout);
freopen_s(&fp, "CONOUT$", "w", stderr);

There are many answers here but I will put here the most important one which everyone should use.

1. Column

 Column(
          children: <Widget>[
            Text('Widget A'), //Can be any widget
            SizedBox(height: 20,), //height is space betweeen your top and bottom widget
            Text('Widget B'), //Can be any widget
          ],
        ),

2. Wrap

     Wrap(
          direction: Axis.vertical, // We have to declare Axis.vertical, otherwise by default widget are drawn in horizontal order
            spacing: 20, // Add spacing one time which is same for all other widgets in the children list
            children: <Widget>[
              Text('Widget A'), // Can be any widget
              Text('Widget B'), // Can be any widget
            ]
        )

Your resource methods won't get hit, so their headers will never get set. The reason is that there is what's called a preflight request before the actual request, which is an OPTIONS request. So the error comes from the fact that the preflight request doesn't produce the necessary headers.

For RESTeasy, you should use CorsFilter. You can see here for some example how to configure it. This filter will handle the preflight request. So you can remove all those headers you have in your resource methods.

complete.cases gives TRUE when all values in a row are not NA

In NodeJS, Buffer.byteLength is a method specifically for this purpose:

let strLengthInBytes = Buffer.byteLength(str); // str is UTF-8

Note that by default the method assumes the string is in UTF-8 encoding. If a different encoding is required, pass it as the second argument.

Is it possible to use a .netrc file on Windows?

Yes: You must:

• define environment variable %HOME% (pre-Git 2.0, no longer needed with Git 2.0+)
• put a _netrc file in %HOME%

If you are using Windows 7/10, in a CMD session, type:

setx HOME %USERPROFILE%

and the %HOME% will be set to 'C:\Users\"username"'.
Go that that folder (cd %HOME%) and make a file called '_netrc'

Note: Again, for Windows, you need a '_netrc' file, not a '.netrc' file.

Its content is quite standard (Replace the <examples> with your values):

machine <hostname1>
login <login1>
password <password1>
machine <hostname2>
login <login2>
password <password2>

Luke mentions in the comments:

Using the latest version of msysgit on Windows 7, I did not need to set the HOME environment variable. The _netrc file alone did the trick.

This is indeed what I mentioned in "Trying to “install” github, .ssh dir not there":
git-cmd.bat included in msysgit does set the %HOME% environment variable:

@if not exist "%HOME%" @set HOME=%HOMEDRIVE%%HOMEPATH%
@if not exist "%HOME%" @set HOME=%USERPROFILE%

??? believes in the comments that "it seems that it won't work for http protocol"

However, I answered that netrc is used by curl, and works for HTTP protocol, as shown in this example (look for 'netrc' in the page): . Also used with HTTP protocol here: "_netrc/.netrc alternative to cURL".

A common trap with with netrc support on Windows is that git will bypass using it if an origin https url specifies a user name.

For example, if your .git/config file contains:

[remote "origin"]
     fetch = +refs/heads/*:refs/remotes/origin/*
     url = https://[email protected]/p/my-project/

Git will not resolve your credentials via _netrc, to fix this remove your username, like so:

[remote "origin"]
     fetch = +refs/heads/*:refs/remotes/origin/*
     url = https://code.google.com/p/my-project/

Alternative solution: With git version 1.7.9+ (January 2012): This answer from Mark Longair details the credential cache mechanism which also allows you to not store your password in plain text as shown below.

With Git 1.8.3 (April 2013):

You now can use an encrypted .netrc (with gpg).
On Windows: %HOME%/_netrc (_, not '.')

A new read-only credential helper (in contrib/) to interact with the .netrc/.authinfo files has been added.

That script would allow you to use gpg-encrypted netrc files, avoiding the issue of having your credentials stored in a plain text file.

Files with the .gpg extension will be decrypted by GPG before parsing.
Multiple -f arguments are OK. They are processed in order, and the first matching entry found is returned via the credential helper protocol.

When no -f option is given, .authinfo.gpg, .netrc.gpg, .authinfo, and .netrc files in your home directory are used in this order.

To enable this credential helper:

git config credential.helper '$shortname -f AUTHFILE1 -f AUTHFILE2'

(Note that Git will prepend "git-credential-" to the helper name and look for it in the path.)

# and if you want lots of debugging info:
git config credential.helper '$shortname -f AUTHFILE -d'

#or to see the files opened and data found:
git config credential.helper '$shortname -f AUTHFILE -v'

See a full example at "Is there a way to skip password typing when using https:// github"

With Git 2.18+ (June 2018), you now can customize the GPG program used to decrypt the encrypted .netrc file.

See commit 786ef50, commit f07eeed (12 May 2018) by Luis Marsano (``).

git-credential-netrc: accept gpg option

git-credential-netrc was hardcoded to decrypt with 'gpg' regardless of the gpg.program option.
This is a problem on distributions like Debian that call modern GnuPG something else, like 'gpg2'

I have been using blockUI to avoid browser incompatibilies on disabled or hidden buttons.

http://malsup.com/jquery/block/#element

Then my buttons have a class autobutton:

  $(".autobutton").click(
     function(event) {
        var nv = $(this).html();
        var nv2 = '<span class="fa fa-circle-o-notch fa-spin" aria-hidden="true"></span> ' + nv;
        $(this).html(nv2);
        var form = $(this).parents('form:first');

        $(this).block({ message: null });
        form.submit();                
        });   

Then a form is like that:

<form>
....
<button class="autobutton">Submit</button>   
</form>

The recommended way in Python 3.5 and above is to use subprocess.run():

from subprocess import run
output = run("pwd", capture_output=True).stdout

The file is created wherever the root of the python interpreter was started.

Eg, you start python in /home/user/program, then the file "test.py" would be located at /home/user/program/test.py

This also works:

^([1-9]|[0-1][0-2])$

[1-9] matches single digits between 1 and 9

[0-1][0-2] matches double digits between 10 and 12

There are some good examples here

I think your assignment is backwards:

a[i] = b[i];

should be:

b[i] = a[i];

My Database table has mismatch column name with the Java Object (@Entity) which leads to throw the above exception.

By updating the table with appropriate column name resolves this issue.

If you have lots of columns and only one is different you could do:

In[1]: grouper = df.groupby('Company Name')
In[2]: res = grouper.count()
In[3]: res['Amount'] = grouper.Amount.sum()
In[4]: res
Out[4]:
                      Organisation Name   Amount
Company Name                                   
Vifor Pharma UK Ltd                  5  4207.93

Note you can then rename the Organisation Name column as you wish.

I was running into the same issue. I discovered the following solution, which has only been tested in Chrome v31:

table {
    table-layout: fixed;
}

tbody {
    display: block;
    overflow: scroll;
}

you do this in the SSMS app, not the SQL. In the toolbar select

Query --> Results To --> Results To File

This:

STR_TO_DATE(t.datestring, '%d/%m/%Y')

...will convert the string into a datetime datatype. To be sure that it comes out in the format you desire, use DATE_FORMAT:

DATE_FORMAT(STR_TO_DATE(t.datestring, '%d/%m/%Y'), '%Y-%m-%d')

If you can't change the datatype on the original column, I suggest creating a view that uses the STR_TO_DATE call to convert the string to a DateTime data type.

Reversing in-place by switching references of opposite indices:

>>> l = [1,2,3,4,5,6,7]    
>>> for i in range(len(l)//2):
...     l[i], l[-1-i] = l[-1-i], l[i]
...
>>> l
[7, 6, 5, 4, 3, 2, 1]

In order to get the values of each variable, you need to treat the function as you would an array:

function data() {
    $a = "abc";
    $b = "def";
    $c = "ghi";
    return array($a, $b, $c);
}

// Assign a variable to the array; 
// I selected $dataArray (could be any name).

$dataArray = data();
list($a, $b, $c) = $dataArray;
echo $a . " ". $b . " " . $c;

//if you just need 1 variable out of 3;
list(, $b, ) = $dataArray;
echo $b;

This is what I usually do ,please refer my function below :

This function can extract first number occurance from any string you can modify and use this function according to your usage

   public static int GetFirstNumber(this string strInsput)
    {
        int number = 0;
        string strNumber = "";
        bool bIsContNo = true;
        bool bNoOccued = false;

        try
        {
            var arry = strInsput.ToCharArray(0, strInsput.Length - 1);

            foreach (char item in arry)
            {
                if (char.IsNumber(item))
                {
                    strNumber = strNumber + item.ToString();

                    bIsContNo = true;

                    bNoOccued = true;
                }
                else
                {
                    bIsContNo = false;
                }

                if (bNoOccued && !bIsContNo)
                {
                    break;
                }


            }

            number = Convert.ToInt32(strNumber);

        }
        catch (Exception ex)
        {

            return 0;
        }

        return number;

    }

man ssh_config says

User

Specifies the user to log in as. This can be useful when a different user name is used on different machines. This saves the trouble of having to remember to give the user name on the command line.

@Tarun answer was working perfectly.but now isnt ,due to the recent changes from Google on google play website.

Just change these from @Tarun answer..

class GetVersionCode extends AsyncTask<Void, String, String> {

    @Override

    protected String doInBackground(Void... voids) {

        String newVersion = null;

        try {
            Document document = Jsoup.connect("https://play.google.com/store/apps/details?id=" + MainActivity.this.getPackageName()  + "&hl=en")
                    .timeout(30000)
                    .userAgent("Mozilla/5.0 (Windows; U; WindowsNT 5.1; en-US; rv1.8.1.6) Gecko/20070725 Firefox/2.0.0.6")
                    .referrer("http://www.google.com")
                    .get();
            if (document != null) {
                Elements element = document.getElementsContainingOwnText("Current Version");
                for (Element ele : element) {
                    if (ele.siblingElements() != null) {
                        Elements sibElemets = ele.siblingElements();
                        for (Element sibElemet : sibElemets) {
                            newVersion = sibElemet.text();
                        }
                    }
                }
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
        return newVersion;

    }


    @Override

    protected void onPostExecute(String onlineVersion) {

        super.onPostExecute(onlineVersion);

        if (onlineVersion != null && !onlineVersion.isEmpty()) {

            if (Float.valueOf(currentVersion) < Float.valueOf(onlineVersion)) {
                //show anything
            }

        }

        Log.d("update", "Current version " + currentVersion + "playstore version " + onlineVersion);

    }
}

and don't forget to add JSoup library

dependencies {
compile 'org.jsoup:jsoup:1.8.3'}

and on Oncreate()

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);


    String currentVersion;
    try {
        currentVersion = getPackageManager().getPackageInfo(getPackageName(), 0).versionName;
    } catch (PackageManager.NameNotFoundException e) {
        e.printStackTrace();
    }

    new GetVersionCode().execute();

}

that's it.. Thanks to this link

You could also use PyAutoGui to send a virtual key presses.

Here's the documentation: https://pyautogui.readthedocs.org/en/latest/

import pyautogui


pyautogui.press('Any key combination')

You can also send keys like the shift key or enter key with:

import pyautogui

pyautogui.press('shift')

Pyautogui can also send straight text like so:

import pyautogui

pyautogui.typewrite('any text you want to type')

As for pressing the "A" key 1000 times, it would look something like this:

import pyautogui

for i in range(999):
    pyautogui.press("a")

alt-tab or other tasks that require more than one key to be pressed at the same time:

import pyautogui

# Holds down the alt key
pyautogui.keyDown("alt")

# Presses the tab key once
pyautogui.press("tab")

# Lets go of the alt key
pyautogui.keyUp("alt")

TRUE and FALSE are keywords, and should not be quoted as strings:

INSERT INTO first VALUES (NULL, 'G22', TRUE);
INSERT INTO first VALUES (NULL, 'G23', FALSE);

By quoting them as strings, MySQL will then cast them to their integer equivalent (since booleans are really just a one-byte INT in MySQL), which translates into zero for any non-numeric string. Thus, you get 0 for both values in your table.

Non-numeric strings cast to zero:

mysql> SELECT CAST('TRUE' AS SIGNED), CAST('FALSE' AS SIGNED), CAST('12345' AS SIGNED);
+------------------------+-------------------------+-------------------------+
| CAST('TRUE' AS SIGNED) | CAST('FALSE' AS SIGNED) | CAST('12345' AS SIGNED) |
+------------------------+-------------------------+-------------------------+
|                      0 |                       0 |                   12345 |
+------------------------+-------------------------+-------------------------+

But the keywords return their corresponding INT representation:

mysql> SELECT TRUE, FALSE;
+------+-------+
| TRUE | FALSE |
+------+-------+
|    1 |     0 |
+------+-------+

Note also, that I have replaced your double-quotes with single quotes as are more standard SQL string enclosures. Finally, I have replaced your empty strings for id with NULL. The empty string may issue a warning.

Which version of .NET are you using? Since .NET 3.5, there's an assembly System.Data.DataSetExtensions, which contains various useful extensions for dataTables, dataRows and the like.

You can try using

row.Field<type>("fieldName");

if that doesn't work, you can do this:

DataTable table = new DataTable();
var myColumn = table.Columns.Cast<DataColumn>().SingleOrDefault(col => col.ColumnName == "myColumnName");
if (myColumn != null)
{
    // just some roww
    var tableRow = table.AsEnumerable().First();
    var myData = tableRow.Field<string>(myColumn);
    // or if above does not work
    myData = tableRow.Field<string>(table.Columns.IndexOf(myColumn));
}

You say that the date is used in connection with web services, so I assume that is serialized into a string at some point.

If this is the case, you should take a look at the setTimeZone method of the DateFormat class. This dictates which time zone that will be used when printing the time stamp.

A simple example:

SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'");
formatter.setTimeZone(TimeZone.getTimeZone("UTC"));

Calendar cal = Calendar.getInstance();
String timestamp = formatter.format(cal.getTime());

Compilating answers here and there, here's a complete set of arr tools to get the work done:

Function getArraySize(arr As Variant)
' returns array size for a n dimention array
' usage result(k) = size of the k-th dimension

Dim ndims As Long
Dim arrsize() As Variant
ndims = getDimensions(arr)
ReDim arrsize(ndims - 1)
For i = 1 To ndims
    arrsize(i - 1) = getDimSize(arr, i)
Next i
getArraySize = arrsize
End Function

Function getDimSize(arr As Variant, dimension As Integer)
' returns size for the given dimension number
    getDimSize = UBound(arr, dimension) - LBound(arr, dimension) + 1
End Function

Function getDimensions(arr As Variant) As Long
' returns number of dimension in an array (ex. sheet range = 2 dimensions)
    On Error GoTo Err
    Dim i As Long
    Dim tmp As Long
    i = 0
    Do While True
        i = i + 1
        tmp = UBound(arr, i)
    Loop
Err:
    getDimensions = i - 1
End Function

Not easily done I am afraid. The problem is Css cannot replace the arrow in a select as this is rendered by the browser. But you can build a new control from div and input elements and Javascript to perform the same function as the select.

Try looking at some of the autocomplete plugins for Jquery for example.

Otherwise there is some info on the select element here:

http://www.devarticles.com/c/a/Web-Style-Sheets/Taming-the-Select/

React.findDOMNode(this.refs.myExample) mentioned in another answer has been deprectaed.

use ReactDOM.findDOMNode from 'react-dom' instead

import ReactDOM from 'react-dom'
let myExample = ReactDOM.findDOMNode(this.refs.myExample)

chunks = [data[100*i:100*(i+1)] for i in range(len(data)/100 + 1)]

This is equivalent to the accepted answer. For example, shortening to batches of 10 for readability:

data = range(35)
print [data[x:x+10] for x in xrange(0, len(data), 10)]
print [data[10*i:10*(i+1)] for i in range(len(data)/10 + 1)]

Outputs:

[[0, 1, 2, 3, 4, 5, 6, 7, 8, 9], [10, 11, 12, 13, 14, 15, 16, 17, 18, 19], [20, 21, 22, 23, 24, 25, 26, 27, 28, 29], [30, 31, 32, 33, 34]]
[[0, 1, 2, 3, 4, 5, 6, 7, 8, 9], [10, 11, 12, 13, 14, 15, 16, 17, 18, 19], [20, 21, 22, 23, 24, 25, 26, 27, 28, 29], [30, 31, 32, 33, 34]]

This is probably because of the column() and row() functions. I am not sure how they are applied in conditional formatting. Try creating a new column with the value from this formula and then use it for your formatting needs.

Using pyquaternion is extremely simple; to install it (while still in python), run in your console:

import pip;
pip.main(['install','pyquaternion'])

Once installed:

  from pyquaternion import Quaternion
  v = [3,5,0]
  axis = [4,4,1]
  theta = 1.2 #radian
  rotated_v = Quaternion(axis=axis,angle=theta).rotate(v)

I think you can use SeriesGroupBy.nunique:

print (df.groupby('param')['group'].nunique())
param
a    2
b    1
Name: group, dtype: int64

Another solution with unique, then create new df by DataFrame.from_records, reshape to Series by stack and last value_counts:

a = df[df.param.notnull()].groupby('group')['param'].unique()
print (pd.DataFrame.from_records(a.values.tolist()).stack().value_counts())
a    2
b    1
dtype: int64

When you have replace: true you get the following piece of DOM:

<div ng-controller="Ctrl" class="ng-scope">
    <div class="ng-binding">hello</div>
</div>

whereas, with replace: false you get this:

<div ng-controller="Ctrl" class="ng-scope">
    <my-dir>
        <div class="ng-binding">hello</div>
    </my-dir>
</div>

So the replace property in directives refer to whether the element to which the directive is being applied (<my-dir> in that case) should remain (replace: false) and the directive's template should be appended as its child,

OR

the element to which the directive is being applied should be replaced (replace: true) by the directive's template.

In both cases the element's (to which the directive is being applied) children will be lost. If you wanted to perserve the element's original content/children you would have to translude it. The following directive would do it:

.directive('myDir', function() {
    return {
        restrict: 'E',
        replace: false,
        transclude: true,
        template: '<div>{{title}}<div ng-transclude></div></div>'
    };
});

In that case if in the directive's template you have an element (or elements) with attribute ng-transclude, its content will be replaced by the element's (to which the directive is being applied) original content.

See example of translusion http://plnkr.co/edit/2DJQydBjgwj9vExLn3Ik?p=preview

See this to read more about translusion.

Here's an updated answer for Angular 4 & 5. TransformRequest and angular.identity were dropped. I've also included the ability to combine files with JSON data in one request.

Angular 5 Solution:

import {HttpClient} from '@angular/common/http';

uploadFileToUrl(files, restObj, uploadUrl): Promise<any> {
  // Note that setting a content-type header
  // for mutlipart forms breaks some built in
  // request parsers like multer in express.
  const options = {} as any; // Set any options you like
  const formData = new FormData();

  // Append files to the virtual form.
  for (const file of files) {
    formData.append(file.name, file)
  }

  // Optional, append other kev:val rest data to the form.
  Object.keys(restObj).forEach(key => {
    formData.append(key, restObj[key]);
  });

  // Send it.
  return this.httpClient.post(uploadUrl, formData, options)
    .toPromise()
    .catch((e) => {
      // handle me
    });
}

Angular 4 Solution:

// Note that these imports below are deprecated in Angular 5
import {Http, RequestOptions} from '@angular/http';

uploadFileToUrl(files, restObj, uploadUrl): Promise<any> {
  // Note that setting a content-type header
  // for mutlipart forms breaks some built in
  // request parsers like multer in express.
  const options = new RequestOptions();
  const formData = new FormData();

  // Append files to the virtual form.
  for (const file of files) {
    formData.append(file.name, file)
  }

  // Optional, append other kev:val rest data to the form.
  Object.keys(restObj).forEach(key => {
    formData.append(key, restObj[key]);
  });

  // Send it.
  return this.http.post(uploadUrl, formData, options)
    .toPromise()
    .catch((e) => {
      // handle me
    });
}

<p class="block-with-text">The Hitch Hiker's Guide to the Galaxy has a few things to say on the subject of towels. A towel, it says, is about the most massivelyuseful thing an interstellar hitch hiker can have. Partly it has great practical value - you can wrap it around you for warmth as you bound across the cold moons of Jaglan Beta; you can lie on it on the brilliant marble-sanded beaches of Santraginus V, inhaling the heady sea vapours; you can sleep under it beneath the stars which shine so redly on the desert world of Kakrafoon; use it to sail a mini raft down the slow heavy river Moth; wet it for use in hand-to-hand-combat; wrap it round your head to ward off noxious fumes or to avoid the gaze of the Ravenous Bugblatter Beast of Traal (a mindboggingly stupid animal, it assumes that if you can't see it, it can't see you - daft as a bush, but very ravenous); you can wave your towel in emergencies as a distress signal, and of course dry yourself off with it if it still seems to be clean enough. More importantly, a towel has immense psychological value. For some reason, if a strag (strag: non-hitch hiker) discovers that a hitch hiker has his towel with him, he will automatically assume that he is also in possession of a toothbrush, face flannel, soap, tin of biscuits, flask, compass, map, ball of string, gnat spray, wet weather gear, space suit etc., etc. Furthermore, the strag will then happily lend the hitch hiker any of these or a dozen other items that the hitch hiker might accidentally have "lost". What the strag will think is that any man who can hitch the length and breadth of the galaxy, rough it, slum it, struggle against terrible odds, win through, and still knows where his towel is is clearly a man to be reckoned with.</p>

Use CURRENT_TIMESTAMP when you need it, instead OF NOW() (which is MySQL)

I had this problem too. I just set my deployment target to 4.3 and left only armv7 architecture and it worked. At point almost everyone has 5, so 4.3 is fine.

You can achieve this using the location object.

location.href = "http://someurl"; 

This may be a little late; but someone will find it useful.

There's a Nuget Package for integrating AdminLTE - a popular Bootstrap template - to MVC5

Simply run this command in your Visual Studio Package Manager console

Install-Package AdminLteMvc

NB: It may take a while to install because it downloads all necessary files as well as create sample full and partial views (.cshtml files) that can guide you as you develop. A sample layout file _AdminLteLayout.cshtml is also provided.

You'll find the files in ~/Views/Shared/ folder

I got the Error even though i was catching the exception.

    try {
        bitmap = BitmapFactory.decodeStream(getAssets().open("kitten.jpg"));
    } catch (IOException e) {
        Log.e("blabla", "Error", e);
        finish();
    }

Issue was that the IOException wasn't imported

import java.io.IOException;

JSONP stands for JSON with Padding.

Here is the site, with great examples, with the explanation from the simplest use of this technique to the most advanced in plane JavaScript:

w3schools.com / JSONP

One of my more favorite techniques described above is Dynamic JSON Result, which allow to send JSON to the PHP file in URL parameter, and let the PHP file also return a JSON object based on the information it gets.

Tools like jQuery also have facilities to use JSONP:

jQuery.ajax({
  url: "https://data.acgov.org/resource/k9se-aps6.json?city=Berkeley",
  jsonp: "callbackName",
  dataType: "jsonp"
}).done(
  response => console.log(response)
);

If you get an error 1044 (42000) when you try to run SQL commands in MySQL (which installed along XAMPP server) cmd prompt, then here's the solution:

1. Close your MySQL command prompt.

2. Open your cmd prompt (from Start menu -> run -> cmd) which will show: C:\Users\User>_

3. Go to MySQL.exe by Typing the following commands:

C:\Users\User>cd\ C:\>cd xampp C:\xampp>cd mysql C:\xxampp\mysql>cd bin C:\xampp\mysql\bin>mysql -u root

1. Now try creating a new database by typing:

   mysql> create database employee;
   

   if it shows:

   Query OK, 1 row affected (0.00 sec)
   mysql>
   

   Then congrats ! You are good to go...

You might just want to use the new TUN.Logging PowerShell module, this can also send a log mail. Just use the Start-Log and/or Start-MailLog cmdlets to start logging and then just use Write-HostLog, Write-WarningLog, Write-VerboseLog, Write-ErrorLog etc. to write to console and log file/mail. Then call Send-Log and/or Stop-Log at the end and voila, you got your logging. Just install it from the PowerShell Gallery via

Install-Module -Name TUN.Logging

Or just follow the link: https://www.powershellgallery.com/packages/TUN.Logging

Documentation of the module can be found here: https://github.com/echalone/TUN/blob/master/PowerShell/Modules/TUN.Logging/TUN.Logging.md

Instructions telling sudo pip install are inherently wrong.

If there is any tutorial out there which says you should do sudo pip then please file a bug against this package. The author is dis-educating Python community, as time has proven sudo pip to be a broken practice.

OSX El Capitan introduced a mechanisms to prevent damaging the operating system files. /System/Library/Frameworks/Python.framework/Versions/2.7/share is one of the protected locations. A normal user has no reason to put or write any files there. This is because the operating system itself relies on these files and sudo pip, with all force given from the above, would unconditionally overwrite them. Usually bad things would not happen, but the chances are there. Apple wants to protect their OS users to accidentally bricking their installation.

Instead, you need to install a Python package, like IPython, locally to the home folder of your user. The easiest way is to create a virtual environment, activate it and then run pip in the virtual environment.

Example:

cd ~  # Go to home directory
virtualenv my-venv
source my-venv/bin/activate
pip install IPython

More info

• Official Python package installation tutorial.

• How to create virtual environments.

Alternatively, one should be able to do pip install --user. But again, no sudo needed and you need to manually set up PATH environment variable.

Wouldn't lambdaj's project function do what you are looking for?

It'll look something like this:

List<UserDTO> userNDtos = project(users, UserDTO.class, on(User.class).getUserName(), on(User.class).getFullName(), .....);

(Define the constructor for UserDTO accordingly...)

Also see here for examples...

name = (city.getName() != null) ? city.getName() : "N/A";

You want to cast the numbers:

double num3 = (double)num1/(double)num2;

Note: If any of the arguments in C# is a double, a double divide is used which results in a double. So, the following would work too:

double num3 = (double)num1/num2;

For more information see:

Dot Net Perls

if num % 2 == 0:
    pass # Even 
else:
    pass # Odd

The % sign is like division only it checks for the remainder, so if the number divided by 2 has a remainder of 0 it's even otherwise odd.

Or reverse them for a little speed improvement, since any number above 0 is also considered "True" you can skip needing to do any equality check:

if num % 2:
    pass # Odd
else:
    pass # Even 

Make the id parameter be a nullable int:

public ActionResult Edit(int? id, User collection)

And then add the validation:

if (Id == null) ...

following will show one table of dataset

DataGridView1.AutoGenerateColumns = true;
DataGridView1.DataSource = ds; // dataset
DataGridView1.DataMember = "TableName"; // table name you need to show

if you want to show multiple tables, you need to create one datatable or custom object collection out of all tables.

if two tables with same table schema

dtAll = dtOne.Copy(); // dtOne = ds.Tables[0]
dtAll.Merge(dtTwo); // dtTwo = dtOne = ds.Tables[1]

DataGridView1.AutoGenerateColumns = true;
DataGridView1.DataSource = dtAll ; // datatable

sample code to mode all tables

DataTable dtAll = ds.Tables[0].Copy();
for (var i = 1; i < ds.Tables.Count; i++)
{
     dtAll.Merge(ds.Tables[i]);
}
DataGridView1.AutoGenerateColumns = true;
DataGridView1.DataSource = dtAll ;

This will create a link titled Share Page which opens the current url in a new window with a height of 570 and width of 520.

Another simple way is to use a tuple:

// Declare a tuple type
let x: [string, number];
// Initialize it
x = ["hello", 10];
// Access elements
console.log("First: " + x["0"] + " Second: " + x["1"]);

Output:

First: hello Second: 10

If you are planning to use JSONP you can use getJSON which made for that. jQuery has helper methods for JSONP.

$.getJSON( 'http://someotherdomain.com/service.svc&callback=?', function( result ) {
       console.log(result);
});

Other answers mainly get all name of object, to get value of property, you can use yourObj[name], for example:

var propNames = Object.getOwnPropertyNames(yourObj);
propNames.forEach(
    function(propName) {
        console.log(
           'name: ' + propName 
        + ' value: ' + yourObj[propName]);
    }
);

None of these answers were sufficient for me, using Jenkins CI v.1.555, Git Client plugin v.1.6.4, and Git plugin 2.0.4.

I wanted a job to build for one Git repository for one specific, fixed (i.e., non-parameterized) tag. I had to cobble together a solution from the various answers plus the "build a Git tag" blog post cited by Thilo.

1. Make sure you push your tag to the remote repository with git push --tags
2. In the "Git Repository" section of your job, under the "Source Code Management" heading, click "Advanced".
3. In the field for Refspec, add the following text: +refs/tags/*:refs/remotes/origin/tags/*
4. Under "Branches to build", "Branch specifier", put */tags/<TAG_TO_BUILD> (replacing <TAG_TO_BUILD> with your actual tag name).

Adding the Refspec for me turned out to be critical. Although it seemed the git repositories were fetching all the remote information by default when I left it blank, the Git plugin would nevertheless completely fail to find my tag. Only when I explicitly specified "get the remote tags" in the Refspec field was the Git plugin able to identify and build from my tag.

Update 2014-5-7: Unfortunately, this solution does come with an undesirable side-effect for Jenkins CI (v.1.555) and the Git repository push notification mechanism à la Stash Webhook to Jenkins: any time any branch on the repository is updated in a push, the tag build jobs will also fire again. This leads to a lot of unnecessary re-builds of the same tag jobs over and over again. I have tried configuring the jobs both with and without the "Force polling using workspace" option, and it seemed to have no effect. The only way I could prevent Jenkins from making the unnecessary builds for the tag jobs is to clear the Refspec field (i.e., delete the +refs/tags/*:refs/remotes/origin/tags/*).

If anyone finds a more elegant solution, please edit this answer with an update. I suspect, for example, that maybe this wouldn't happen if the refspec specifically was +refs/tags/<TAG TO BUILD>:refs/remotes/origin/tags/<TAG TO BUILD> rather than the asterisk catch-all. For now, however, this solution is working for us, we just remove the extra Refspec after the job succeeds.

Similar to Etienne's solution, a simple table formats nicely:

| | |
|-|-|
|`NOTE` | This is something I want you to notice. It has a lot of text, and I want that text to wrap within a cell to the right of the `NOTE`, instead of under it.|

Another alternative (which comes with more emphasis), is to make the content the header of a body-less table:

|`NOTE` | This is something I want you to notice. It has a lot of text, and I want that text to wrap within a cell to the right of the `NOTE`, instead of under it.|
|-|-|

Finally, you can include a horizontal line (thematic break) to create a closed box (although the line style is a little different than the header line in the table):

| | |
|-|-|
|`NOTE` | This is something I want you to notice. It has a lot of text, and I want that text to wrap within a cell to the right of the `NOTE`, instead of under it.|

---

Note the empty line after the text.

You can do it just using a loop.

    $singleArray = array();

    foreach ($multiDimensionalArray as $key => $value){
        $singleArray[$key] = $value['plan'];
    }

the above script may not run in ksh. you have to use the 'let' opparand to assing the value and then echo it.

val1=4

val2=3

let val3=$val1+$val2

echo $val3 

The Best Answer to dropping the table containing foreign constraints is :

• Step 1 : Drop the Primary key of the table.
• Step 2 : Now it will prompt whether to delete all the foreign references or not.
• Step 3 : Delete the table.

Some of the provided answers did not work for me (javaw.exe still running after closing the window) or, eclipse showed an exception after the application was closed.

On the other hand, this works perfectly:

primaryStage.setOnCloseRequest(new EventHandler<WindowEvent>() {
    @Override
    public void handle(WindowEvent t) {
        Platform.exit();
        System.exit(0);
    }
});

Change it to:

<div style="background-color:black; overflow:hidden;" onmouseover="this.bgColor='white'">
<div style="float:left">hello</div>
<div style="float:right">world</div>
</div>

Basically the outer div only contains floats. Floats are removed from the normal flow. As such the outer div really contains nothing and thus has no height. It really is black but you just can't see it.

The overflow:hidden property basically makes the outer div enclose the floats. The other way to do this is:

<div style="background-color:black" onmouseover="this.bgColor='white'">
<div style="float:left">hello</div>
<div style="float:right">world</div>
<div style="clear:both></div>
</div>

Oh and just for completeness, you should really prefer classes to direct CSS styles.

Default values are set by configuring corresponding entity. Before binding the entity to form set its color field to "#0000FF":

// controller action
$project = new Project();
$project->setColor('#0000FF');
$form = $this->createForm(new ProjectType(), $project);

The problem is that you are returning the toString() of the call to Base64.encodeBase64(bytes) which returns a byte array. So what you get in the end is the default string representation of a byte array, which corresponds to the output you get.

Instead, you should do:

encodedfile = new String(Base64.encodeBase64(bytes), "UTF-8");

You can't. Nginx doesn't really support variables in config files, and its developers mock everyone who ask for this feature to be added:

"[Variables] are rather costly compared to plain static configuration. [A] macro expansion and "include" directives should be used [with] e.g. sed + make or any other common template mechanism." http://nginx.org/en/docs/faq/variables_in_config.html

You should either write or download a little tool that will allow you to generate config files from placeholder config files.

Update The code below still works, but I've wrapped it all up into a small PHP program/library called Configurator also on Packagist, which allows easy generation of nginx/php-fpm etc config files, from templates and various forms of config data.

e.g. my nginx source config file looks like this:

location  / {
    try_files $uri /routing.php?$args;
    fastcgi_pass   unix:%phpfpm.socket%/php-fpm-www.sock;
    include       %mysite.root.directory%/conf/fastcgi.conf;
}

And then I have a config file with the variables defined:

phpfpm.socket=/var/run/php-fpm.socket
mysite.root.directory=/home/mysite

And then I generate the actual config file using that. It looks like you're a Python guy, so a PHP based example may not help you, but for anyone else who does use PHP:

<?php

require_once('path.php');

$filesToGenerate = array(
    'conf/nginx.conf' => 'autogen/nginx.conf',
    'conf/mysite.nginx.conf' => 'autogen/mysite.nginx.conf',
    'conf/mysite.php-fpm.conf' => 'autogen/mysite.php-fpm.conf',
    'conf/my.cnf' => 'autogen/my.cnf',
);

$environment = 'amazonec2';

if ($argc >= 2){
    $environmentRequired = $argv[1];

    $allowedVars = array(
        'amazonec2',
        'macports',
    );

    if (in_array($environmentRequired, $allowedVars) == true){
        $environment = $environmentRequired;
    }
}
else{
    echo "Defaulting to [".$environment."] environment";
}

$config = getConfigForEnvironment($environment);

foreach($filesToGenerate as $inputFilename => $outputFilename){
    generateConfigFile(PATH_TO_ROOT.$inputFilename, PATH_TO_ROOT.$outputFilename, $config);
}


function    getConfigForEnvironment($environment){
    $config = parse_ini_file(PATH_TO_ROOT."conf/deployConfig.ini", TRUE);
    $configWithMarkers = array();
    foreach($config[$environment] as $key => $value){
        $configWithMarkers['%'.$key.'%'] = $value;
    }

    return  $configWithMarkers;
}


function    generateConfigFile($inputFilename, $outputFilename, $config){

    $lines = file($inputFilename);

    if($lines === FALSE){
        echo "Failed to read [".$inputFilename."] for reading.";
        exit(-1);
    }

    $fileHandle = fopen($outputFilename, "w");

    if($fileHandle === FALSE){
        echo "Failed to read [".$outputFilename."] for writing.";
        exit(-1);
    }

    $search = array_keys($config);
    $replace = array_values($config);

    foreach($lines as $line){
        $line = str_replace($search, $replace, $line);
        fwrite($fileHandle, $line);
    }

    fclose($fileHandle);
}

?>

And then deployConfig.ini looks something like:

[global]

;global variables go here.

You can use Array#filter function and additional array for storing sorted values;

var recordsSorted = []

ids.forEach(function(e) {
    recordsSorted.push(records.filter(function(o) {
        return o.empid === e;
    }));
});

console.log(recordsSorted);

Result:

[ [ { empid: 1, fname: 'X', lname: 'Y' } ],
  [ { empid: 4, fname: 'C', lname: 'Y' } ],
  [ { empid: 5, fname: 'C', lname: 'Y' } ] ]

In case you are looking to include the font awesome library without having to do module imports and npm installs, put this in the head section of your React index.html page:

public/index.html (in head section)

<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.min.css"/>

Then in your component (such as App.js) just use standard font awesome class convention. Just remember to use className instead of class:

<button className='btn'><i className='fa fa-home'></i></button>

127.0.0.1 restricts access on every interface on port 8000 except development computer. change it to 0.0.0.0:8000 this will allow connection from curl.

Not sure if this will benefit anybody, but if you are using Azure CloudShell PowerShell you can just type:

code file.txt

And Visual Studio code will popup with the file to be edit, pretty great.

You could use:

line.Replace(@"\", "");

or

line.Replace(@"\", string.Empty);

If no From: header is specified in the e-mail headers, the MTA uses the full name of the current user, in this case "Apache". You can edit full user names in /etc/passwd

If you want a full-featured, yet succinct approach to handling real-world data structures which are often nested, and can even contain cycles, I recommend looking at the remap utility from the boltons utility package.

After pip install boltons or copying iterutils.py into your project, just do:

from boltons.iterutils import remap

drop_falsey = lambda path, key, value: bool(value)
clean = remap(metadata, visit=drop_falsey)

This page has many more examples, including ones working with much larger objects from Github's API.

It's pure-Python, so it works everywhere, and is fully tested in Python 2.7 and 3.3+. Best of all, I wrote it for exactly cases like this, so if you find a case it doesn't handle, you can bug me to fix it right here.

You have extra brackets in Hours property;

public  object Hours { get; set; }}

**It is Simple, just follow 2 steps. Step #1. Fire query "Delete from tableName", It will delete all records from table.

Step #2. There is table named "sqlite_sequence" in Sqlite Database, just browse it and you can set sequence table wise to "0" so it will start from auto id "1".** See the screenshot attached.

I guess that this code should answer your question:

use strict;
use warnings;

my @keys = qw/one two three two/;
my %hash;
for my $key (@keys)
{
    $hash{$key}++;
}

for my $key (keys %hash)
{
   print "$key: ", $hash{$key}, "\n";
}

Output:

three: 1
one: 1
two: 2

The iteration can be simplified to:

$hash{$_}++ for (@keys);

(See $_ in perlvar.) And you can even write something like this:

$hash{$_}++ or print "Found new value: $_.\n" for (@keys);

Which reports each key the first time it’s found.

I just met and solved this problem by myself. My problem is a little different. I'm using visual studio on Windows 10. When I create the project, the Target Platform Version was automatically set to 10.0.15063.0. But there is no kernel32.lib for this version of SDK, neither are other necessary header files and lib files. So I modified the Target Platform Version to 8.1. And it worked.

Environment:

• Windows 10
• Visual Studio 2015
• Visual C++

Solution:

1. Open the project's Property Page;
2. Navigate to General page;
3. Modify Target Platform Version to the desired target platform (e.g. 8.1).

There is code and binaries available here for a console app that can export private keys marked as non-exportable, and it won't trigger antivirus apps like mimikatz will.

The code is based on a paper by the NCC Group. will need to run the tool with the local system account, as it works by writing directly to memory used by Windows' lsass process, in order to temporarily mark keys as exportable. This can be done using PsExec from SysInternals' PsTools:

1. Spawn a new command prompt running as the local system user:

PsExec64.exe -s -i cmd

2. In the new command prompt, run the tool:

exportrsa.exe

3. It will loop over every Local Computer store, searching for certificates with a private key. For each one, it will prompt you for a password - this is the password you want to secure the exported PFX file with, so can be whatever you want

I don't think a message box is the best way to go with this as you would need the VB code running in a loop to check the cell contents, or unless you plan to run the macro manually. In this case I think it would be better to add conditional formatting to the cell to change the background to red (for example) if the value exceeds the upper limit.

The following may be useful since I got here looking for a slightly different solution. My script needed to automatically loop through input elements and had to return their values (for jQuery.post() function), the problem was with checkboxes returning their values regardless of checked status. This was my solution:

jQuery.fn.input_val = function(){

    if(jQuery(this).is("input[type=checkbox]")) {
        if(jQuery(this).is(":checked")) {
            return jQuery(this).val();
        } else {
            return false;
        }
    } else {
        return jQuery(this).val();
    }
};

Usage:

jQuery(".element").input_val();

If the given input field is a checkbox, the input_val function only returns a value if its checked. For all other elements, the value is returned regardless of checked status.

Modify the DataNode class so that it implements Comparable interface.

public int compareTo(DataNode o)
{
     return(degree - o.degree);
}

then just use

Collections.sort(nodeList);

The best way to do this is using WordPress class to authenticate users. Here is my solutions:

1. Include following WordPress PHP file:

include_once(dirname(dirname(dirname(__FILE__))) . DIRECTORY_SEPARATOR . "wp-includes" . DIRECTORY_SEPARATOR . "class-phpass.php");

2. Create an object of PasswordHash class:

$wp_hasher = new PasswordHash(8, true);

3. call CheckPassword function to authenticate user:

$check = $wp_hasher->CheckPassword($password, $row['user_pass']);

4. check $check variable:

if($check) {
   echo "password is correct";
} else {
   echo "password is incorrect";
}

Please Note that: $password is the un-hashed password in clear text whereas $row['user_pass'] is the hashed password that you need to fetch from the database.

You may try adding an additional argument of type HttpServletRequest to the getUrlValue() method:

@RequestMapping(value ="/",produces = "application/json")
public String getURLValue(HttpServletRequest request){
    String test = request.getRequestURI();
    return test;
}

public void setHoursWorked(){
    hoursWorked = hours;
}

You haven't defined hours inside that method. hours is not passed in as a parameter, it's not declared as a variable, and it's not being used as a class member, so you get that error.

It may help:

Use the domready event and reopen the info window and show the hidden content after the domready event fires twice to ensure all of the dom elements have been loaded.

// map is created using google.maps.Map() 
// marker is created using google.maps.Marker()
// set the css for the content div .infowin-content { visibility: hidden; } 

infowindow = new google.maps.InfoWindow();    
infowindow.setContent("<div class='infowin-content'>Content goes here</div>");
infowindow.setPosition(marker.getPosition());
infowindow.set("isdomready", false);
infowindow.open(map);   

// On Dom Ready
google.maps.event.addListener(infowindow, 'domready', function () {
    if (infowindow.get("isdomready")) {
        // show the infowindow by setting css 
        jQuery('.infowin-content').css('visibility', 'visible');               
    }
    else {
        // trigger a domready event again.
        google.maps.event.trigger(infowindow, 'content_changed');
        infowindow.set("isdomready", true);
    }
}

I tried just doing a setTimeout(/* show infowin callback */, 100), but sometimes that didn't work still if the content (ie: images) took too long to load.

Hope this works for you.

In your layout you'll need something to display the text. A TextView is the obvious choice. So you'll have something like this:

<TextView 
    android:id="@+id/text_view" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent"/>

And your code will look like this:

//Find the directory for the SD Card using the API
//*Don't* hardcode "/sdcard"
File sdcard = Environment.getExternalStorageDirectory();

//Get the text file
File file = new File(sdcard,"file.txt");

//Read text from file
StringBuilder text = new StringBuilder();

try {
    BufferedReader br = new BufferedReader(new FileReader(file));
    String line;

    while ((line = br.readLine()) != null) {
        text.append(line);
        text.append('\n');
    }
    br.close();
}
catch (IOException e) {
    //You'll need to add proper error handling here
}

//Find the view by its id
TextView tv = (TextView)findViewById(R.id.text_view);

//Set the text
tv.setText(text);

This could go in the onCreate() method of your Activity, or somewhere else depending on just what it is you want to do.

So something interesting that I found a while ago while working with canvas that might be helpful:

To resize the canvas control on its own, you need to use the height="" and width="" attributes (or canvas.width/canvas.height elements). If you use CSS to resize the canvas, it will actually stretch (i.e.: resize) the content of the canvas to fit the full canvas (rather than simply increasing or decreasing the area of the canvas.

It'd be worth a shot to try drawing the image into a canvas control with the height and width attributes set to the size of the image and then using CSS to resize the canvas to the size you're looking for. Perhaps this would use a different resizing algorithm.

It should also be noted that canvas has different effects in different browsers (and even different versions of different browsers). The algorithms and techniques used in the browsers is likely to change over time (especially with Firefox 4 and Chrome 6 coming out so soon, which will place heavy emphasis on canvas rendering performance).

In addition, you may want to give SVG a shot, too, as it likely uses a different algorithm as well.

Best of luck!

Simple way is to reset the index of the DataFrame prior to filtering:

df_reset = df.reset_index()
df_reset[df_reset['BoolCol']].index.tolist()

Bit hacky, but it's quick!

There is no concept of folders or directories in S3. You can create file names like "abc/xys/uvw/123.jpg", which many S3 access tools like S3Fox show like a directory structure, but it's actually just a single file in a bucket.

I did it using Javascript. I add three css classes to the html element:

ie<version>
lte-ie<version>
lt-ie<version + 1>

So for IE7, it adds ie7, lte-ie7 ..., lt-ie8 ...

Here is the javascript code:

(function () {
    function getIEVersion() {
        var ua = window.navigator.userAgent;
        var msie = ua.indexOf('MSIE ');
        var trident = ua.indexOf('Trident/');

        if (msie > 0) {
            // IE 10 or older => return version number
            return parseInt(ua.substring(msie + 5, ua.indexOf('.', msie)), 10);
        } else if (trident > 0) {
            // IE 11 (or newer) => return version number
            var rv = ua.indexOf('rv:');
            return parseInt(ua.substring(rv + 3, ua.indexOf('.', rv)), 10);
        } else {
            return NaN;
        }
    };

    var ieVersion = getIEVersion();

    if (!isNaN(ieVersion)) { // if it is IE
        var minVersion = 6;
        var maxVersion = 13; // adjust this appropriately

        if (ieVersion >= minVersion && ieVersion <= maxVersion) {
            var htmlElem = document.getElementsByTagName('html').item(0);

            var addHtmlClass = function (className) { // define function to add class to 'html' element
                htmlElem.className += ' ' + className;
            };

            addHtmlClass('ie' + ieVersion); // add current version
            addHtmlClass('lte-ie' + ieVersion);

            if (ieVersion < maxVersion) {
                for (var i = ieVersion + 1; i <= maxVersion; ++i) {
                    addHtmlClass('lte-ie' + i);
                    addHtmlClass('lt-ie' + i);
                }
            }
        }
    }
})();

Thereafter, you use the .ie<version> css class in your stylesheet as described by potench.

(Used Mario's detectIE function in Check if user is using IE with jQuery)

The benefit of having lte-ie8 and lt-ie8 etc is that it you can target all browser less than or equal to IE9, that is IE7 - IE9.

A potentially simpler solution:

get-service "servicename*" | Where {$_.Status -eq 'Stopped'} | start-service

I suspect that the xcopy command is the magic bullet you're looking for.

It can copy files, directories, and even entire drives while preserving the original directory hierarchy. There are also a handful of additional options available, compared to the basic copy command.

Check out the documentation here.

If your batch file only needs to run on Windows Vista or later, you can use robocopy instead, which is an even more powerful tool than xcopy, and is now built into the operating system. It's documentation is available here.

useEffect can hook on a certain prop or state. so, the thing you need to do to avoid infinite loop hook is binding some variable or state to effect

For Example:

useEffect(myeffectCallback, [])

above effect will fire only once the component has rendered. this is similar to componentDidMount lifecycle

const [something, setSomething] = withState(0)
const [myState, setMyState] = withState(0)
useEffect(() => {
  setSomething(0)
}, myState)

above effect will fire only my state has changed this is similar to componentDidUpdate except not every changing state will fire it.

You can read more detail though this link

My solution might not be the cleanest but it should work with no problems. The logic is simply to create a static variable to store your data on the Service and update your view each second on your Activity.

Let's say that you have a String on your Service that you want to send it to a TextView on your Activity. It should look like this

Your Service:

public class TestService extends Service {
    public static String myString = "";
    // Do some stuff with myString

Your Activty:

public class TestActivity extends Activity {
    TextView tv;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        tv = new TextView(this);
        setContentView(tv);
        update();
        Thread t = new Thread() {
            @Override
            public void run() {
                try {
                    while (!isInterrupted()) {
                        Thread.sleep(1000);
                        runOnUiThread(new Runnable() {
                            @Override
                            public void run() {
                                update();
                            }
                        });
                    }
                } catch (InterruptedException ignored) {}
            }
        };
        t.start();
        startService(new Intent(this, TestService.class));
    }
    private void update() {
        // update your interface here
        tv.setText(TestService.myString);
    }
}

You will need to run

sudo apt-get install build-essential

first assuming you're on a debain/ubuntu system

Lets say your company makes 4 different products, your client has another 3 different products from another 3 different companies.

Someday the client thought, why don't we integrate all our systems into one huge system. Ten minutes later their IT department said that will take 2 years.

You (the wise developer) said, why don't we just integrate all the different systems and make them work together in a homogeneous environment? The client manager staring at you... You continued, we will use a Middleware, we will study the Inputs/Outputs of all different systems, the resources they use and then choose an appropriate Middleware framework.

Still explaining to the non tech manager
With Middleware framework in the middle, the first system will produce X stuff, the system Y and Z would consume those outputs and so on.

Timer for jQuery - smaller, working, tested.

    var sec = 0;_x000D_
    function pad ( val ) { return val > 9 ? val : "0" + val; }_x000D_
    setInterval( function(){_x000D_
        $("#seconds").html(pad(++sec%60));_x000D_
        $("#minutes").html(pad(parseInt(sec/60,10)));_x000D_
    }, 1000);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<span id="minutes"></span>:<span id="seconds"></span>

Pure JavaScript:

    var sec = 0;_x000D_
    function pad ( val ) { return val > 9 ? val : "0" + val; }_x000D_
    setInterval( function(){_x000D_
        document.getElementById("seconds").innerHTML=pad(++sec%60);_x000D_
        document.getElementById("minutes").innerHTML=pad(parseInt(sec/60,10));_x000D_
    }, 1000);

<span id="minutes"></span>:<span id="seconds"></span>

Update:

This answer shows how to pad.

Stopping setInterval ^MDN is achieved with clearInterval ^MDN

var timer = setInterval ( function(){...}, 1000 );
...
clearInterval ( timer );

Fiddle

Here is a simple example. I suppose it will be easy to understand:

import java.awt.*;
import javax.swing.JFrame;
import javax.swing.JPanel;

public class Graph extends JFrame {
JFrame f = new JFrame();
JPanel jp;


public Graph() {
    f.setTitle("Simple Drawing");
    f.setSize(300, 300);
    f.setDefaultCloseOperation(EXIT_ON_CLOSE);

    jp = new GPanel();
    f.add(jp);
    f.setVisible(true);
}

public static void main(String[] args) {
    Graph g1 = new Graph();
    g1.setVisible(true);
}

class GPanel extends JPanel {
    public GPanel() {
        f.setPreferredSize(new Dimension(300, 300));
    }

    @Override
    public void paintComponent(Graphics g) {
        //rectangle originates at 10,10 and ends at 240,240
        g.drawRect(10, 10, 240, 240);
        //filled Rectangle with rounded corners.    
        g.fillRoundRect(50, 50, 100, 100, 80, 80);
    }
}

}

And the output looks like this:

If you use a pem file to authenticate u can use the following command (which will exclude files with something extension):

rsync -Lavz -e "ssh -i <full-path-to-pem> -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null" --exclude "*.something" --progress <path inside local host> <user>@<host>:<path inside remote host>

The -L means follow links (copy files not links). Use full path to your pem file and not relative.

Using sshfs is not recommended since it works slowly. Also, the combination of find and scp that was presented above is also a bad idea since it will open a ssh session per file which is too expensive.

In Eclipse:
Project -> properties -> java Build Path -> libraries

Remove existing JRE System Library, then Add Library -> JRE System library -> next -> ok

Error will be removed.

Got into the same predicament. I ended up with the following. So here I am not injecting the scope object into the factory, but setting the $scope in the controller itself using the concept of promise returned by $http service.

(function () {
    getDataFactory = function ($http)
    {
        return {
            callWebApi: function (reqData)
            {
                var dataTemp = {
                    Page: 1, Take: 10,
                    PropName: 'Id', SortOrder: 'Asc'
                };

                return $http({
                    method: 'GET',
                    url: '/api/PatientCategoryApi/PatCat',
                    params: dataTemp, // Parameters to pass to external service
                    headers: { 'Content-Type': 'application/Json' }
                })                
            }
        }
    }
    patientCategoryController = function ($scope, getDataFactory) {
        alert('Hare');
        var promise = getDataFactory.callWebApi('someDataToPass');
        promise.then(
            function successCallback(response) {
                alert(JSON.stringify(response.data));
                // Set this response data to scope to use it in UI
                $scope.gridOptions.data = response.data.Collection;
            }, function errorCallback(response) {
                alert('Some problem while fetching data!!');
            });
    }
    patientCategoryController.$inject = ['$scope', 'getDataFactory'];
    getDataFactory.$inject = ['$http'];
    angular.module('demoApp', []);
    angular.module('demoApp').controller('patientCategoryController', patientCategoryController);
    angular.module('demoApp').factory('getDataFactory', getDataFactory);    
}());

For those who want isoWeek to be the default you can modify moment's behaviour as such:

const moment = require('moment');
const proto = Object.getPrototypeOf(moment());

const {startOf, endOf} = proto;
proto.startOf = function(period) {
  if (period === 'week') {
    period = 'isoWeek';
  }
  return startOf.call(this, period);
};
proto.endOf = function(period) {
  if (period === 'week') {
    period = 'isoWeek';
  }
  return endOf.call(this, period);
};

Now you can simply use someDate.startOf('week') without worrying you'll get sunday or having to think about whether to use isoweek or isoWeek etc.

Plus you can store this in a variable like const period = 'week' and use it safely in subtract() or add() operations, e.g. moment().subtract(1, period).startOf(period);. This won't work with period being isoWeek.

SCREEN:

NOTE: screen is actually not able to send hex, as far as I know. To do that, use echo or printf

I was using the suggestions in this post to write to a serial port, then using the info from another post to read from the port, with mixed results. I found that using screen is an "easier" solution, since it opens a terminal session directly with that port. (I put easier in quotes, because screen has a really weird interface, IMO, and takes some further reading to figure it out.)

You can issue this command to open a screen session, then anything you type will be sent to the port, plus the return values will be printed below it:

screen /dev/ttyS0 19200,cs8

(Change the above to fit your needs for speed, parity, stop bits, etc.) I realize screen isn't the "linux command line" as the post specifically asks for, but I think it's in the same spirit. Plus, you don't have to type echo and quotes every time.

ECHO:

Follow praetorian droid's answer. HOWEVER, this didn't work for me until I also used the cat command (cat < /dev/ttyS0) while I was sending the echo command.

PRINTF:

I found that one can also use printf's '%x' command:

c="\x"$(printf '%x' 0x12)
printf $c >> $SERIAL_COMM_PORT

Again, for printf, start cat < /dev/ttyS0 before sending the command.

targetList = list1.Concat(list2).ToList();

It's working fine I think so. As previously said, Concat returns a new sequence and while converting the result to List, it does the job perfectly. Implicit conversions may fail sometimes when using the AddRange method.

Quiet Late though!.

This method is properly tested and it converts the excel to DataSet.

public DataSet Dtl()
        {
            //Instance reference for Excel Application
            Microsoft.Office.Interop.Excel.Application objXL = null;        
            //Workbook refrence
            Microsoft.Office.Interop.Excel.Workbook objWB = null;
            DataSet ds = new DataSet();
            try
            {
                objXL = new Microsoft.Office.Interop.Excel.Application();
                objWB = objXL.Workbooks.Open(@"Book1.xlsx");//Your path to excel file.
                foreach (Microsoft.Office.Interop.Excel.Worksheet objSHT in objWB.Worksheets)
                {
                    int rows = objSHT.UsedRange.Rows.Count;
                    int cols = objSHT.UsedRange.Columns.Count;
                    DataTable dt = new DataTable();
                    int noofrow = 1;
                    //If 1st Row Contains unique Headers for datatable include this part else remove it
                    //Start
                    for (int c = 1; c <= cols; c++)
                    {
                        string colname = objSHT.Cells[1, c].Text;
                        dt.Columns.Add(colname);
                        noofrow = 2;
                    }
                    //END
                    for (int r = noofrow; r <= rows; r++)
                    {
                        DataRow dr = dt.NewRow();

                        {
                            dr[c - 1] = objSHT.Cells[r, c].Text;
                        }
                        dt.Rows.Add(dr);
                    }
                   ds.Tables.Add(dt);
                }
                //Closing workbook
                objWB.Close();
                //Closing excel application
                objXL.Quit();
                return ds;
            }

            catch (Exception ex)
            {

                //Closing work book

                return ds;
            }
        }

tl;dr

LocalDate.of( 2017 , Month.JANUARY , 23 ) 
         .plusDays( 1 )

java.time

Best to avoid the java.util.Date class altogether. But if you must do so, you can convert between the troublesome old legacy date-time classes and the modern java.time classes. Look to new methods added to the old classes.

Instant

The Instant class, is close to being equivalent to Date, both being a moment on the timeline. Instant resolves to nanoseconds, while Date is milliseconds.

Instant instant = myUtilDate.toInstant() ;

You could add a day to this, but keep in mind this in UTC. So you will not be accounting for anomalies such as Daylight Saving Time. Specify the unit of time with the ChronoUnit class.

Instant nextDay = instant.plus( 1 , ChronoUnit.DAYS ) ;

ZonedDateTime

If you want to be savvy with time zones, specify a ZoneId to get a ZonedDateTime. Specify a proper time zone name in the format of continent/region, such as America/Montreal, Africa/Casablanca, or Pacific/Auckland. Never use the 3-4 letter abbreviation such as EST or IST as they are not true time zones, not standardized, and not even unique(!).

ZoneId z = ZoneId.of( "America/Montreal" ) ;
ZonedDateTime zdt = instant.atZone( z ) ;
ZonedDateTime zdtNextDay = zdt.plusDays( 1 ) ;

You can also represent your span-of-time to be added, the one day, as a Period.

Period p = Period.ofDays( 1 ) ;
ZonedDateTime zdt = ZonedDateTime.now( z ).plus( p ) ;

You may want the first moment of that next day. Do not assume the day starts at 00:00:00. Anomalies such as Daylight Saving Time (DST) mean the day may start at another time, such as 01:00:00. Let java.time determine the first moment of the day on that date in that zone.

LocalDate today = LocalDate.now( z ) ;
LocalDate tomorrow = today.plus( p ) ;
ZonedDateTime zdt = tomorrow.atStartOfDay( z ) ;

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, Java SE 10, and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android (<26), the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

Update: The Joda-Time library is now in maintenance mode. The team advises migration to the java.time classes. I am leaving this section intact for history.

Joda-Time

The Joda-Time 2.3 library makes this kind of date-time work much easier. The java.util.Date class bundled with Java is notoriously troublesome, and should be avoided.

Here is some example code.

Your java.util.Date is converted to a Joda-Time DateTime object. Unlike a j.u.Date, a DateTime truly knows its assigned time zone. Time zone is crucial as adding a day to get the same wall-clock time tomorrow might mean making adjustments such as for a 23-hour or 25-hour day in the case of Daylight Saving Time (DST) here in the United States. If you specify the time zone, Joda-Time can make that kind of adjustment. After adding a day, we convert the DateTime object back into a java.util.Date object.

java.util.Date yourDate = new java.util.Date();

// Generally better to specify your time zone rather than rely on default.
org.joda.time.DateTimeZone timeZone = org.joda.time.DateTimeZone.forID( "America/Los_Angeles" );
DateTime now = new DateTime( yourDate, timeZone );
DateTime tomorrow = now.plusDays( 1 );
java.util.Date tomorrowAsJUDate = tomorrow.toDate();

Dump to console…

System.out.println( "yourDate: " + yourDate );
System.out.println( "now: " + now );
System.out.println( "tomorrow: " + tomorrow );
System.out.println( "tomorrowAsJUDate: " + tomorrowAsJUDate );

When run…

This one $("#yourDiv").load(" #yourDiv > *"); is the best if you are planning to just reload a <div>

Make sure to use an id and not a class. Also, remember to paste <script src="https://code.jquery.com/jquery-3.5.1.js"></script> in the <head> section of the html file, if you haven't already. In opposite case it won't work.

Use chown to change ownership and chmod to change rights.

use the -R option to apply the rights for all files inside of a directory too.

Note that both these commands just work for directories too. The -R option makes them also change the permissions for all files and directories inside of the directory.

For example

sudo chown -R username:group directory

will change ownership (both user and group) of all files and directories inside of directory and directory itself.

sudo chown username:group directory

will only change the permission of the folder directory but will leave the files and folders inside the directory alone.

you need to use sudo to change the ownership from root to yourself.

Edit:

Note that if you use chown user: file (Note the left-out group), it will use the default group for that user.

Also You can change the group ownership of a file or directory with the command:

chgrp group_name file/directory_name

You must be a member of the group to which you are changing ownership to.

You can find group of file as follows

# ls -l file
-rw-r--r-- 1 root family 0 2012-05-22 20:03 file

# chown sujit:friends file

User 500 is just a normal user. Typically user 500 was the first user on the system, recent changes (to /etc/login.defs) has altered the minimum user id to 1000 in many distributions, so typically 1000 is now the first (non root) user.

What you may be seeing is a system which has been upgraded from the old state to the new state and still has some processes knocking about on uid 500. You can likely change it by first checking if your distro should indeed now use 1000, and if so alter the login.defs file yourself, the renumber the user account in /etc/passwd and chown/chgrp all their files, usually in /home/, then reboot.

But in answer to your question, no, you should not really be worried about this in all likelihood. It'll be showing as "500" instead of a username because o user in /etc/passwd has a uid set of 500, that's all.

Also you can show your current numbers using id i'm willing to bet it comes back as 1000 for you.

If you are inside a .then() block and you want to execute a settimeout()

            .then(() => {
                console.log('wait for 10 seconds . . . . ');
                return new Promise(function(resolve, reject) { 
                    setTimeout(() => {
                        console.log('10 seconds Timer expired!!!');
                        resolve();
                    }, 10000)
                });
            })
            .then(() => {
                console.log('promise resolved!!!');

            })

output will as shown below

wait for 10 seconds . . . .
10 seconds Timer expired!!!
promise resolved!!!

Happy Coding!

Swift 4.x

extension UIButton {
    func centerTextAndImage(spacing: CGFloat) {
        let insetAmount = spacing / 2
        let writingDirection = UIApplication.shared.userInterfaceLayoutDirection
        let factor: CGFloat = writingDirection == .leftToRight ? 1 : -1

        self.imageEdgeInsets = UIEdgeInsets(top: 0, left: -insetAmount*factor, bottom: 0, right: insetAmount*factor)
        self.titleEdgeInsets = UIEdgeInsets(top: 0, left: insetAmount*factor, bottom: 0, right: -insetAmount*factor)
        self.contentEdgeInsets = UIEdgeInsets(top: 0, left: insetAmount, bottom: 0, right: insetAmount)
    }
}

Usage:

button.centerTextAndImage(spacing: 10.0)

what this means ? is there any problem in my code

It means that you are accessing a location or index which is not present in collection.

To find this, Make sure your Gridview has 5 columns as you are using it's 5th column by this line

dataGridView1.Columns[4].Name = "Amount";

Here is the image which shows the elements of an array. So if your gridview has less column then the (index + 1) by which you are accessing it, then this exception arises.

While Richard's is what you want if you do want to go with a typedef, I'd suggest that it's probably not a particularly good idea in this instance, as you lose sight of it being a pointer, while not gaining anything.

If you were treating it a a counted string, or something with additional functionality, that might be different, but I'd really recommend that in this instance, you just get familiar with the 'standard' C string implementation being a 'char *'...

If the "many" model does not justify the creation of a model per-se (not the case here, but it might benefits other people), another alternative would be to rely on specific PostgreSQL data types, via the Django Contrib package

Postgres can deal with Array or JSON data types, and this may be a nice workaround to handle One-To-Many when the many-ies can only be tied to a single entity of the one.

Postgres allows you to access single elements of the array, which means that queries can be really fast, and avoid application-level overheads. And of course, Django implements a cool API to leverage this feature.

It obviously has the disadvantage of not being portable to others database backend, but I thougt it still worth mentionning.

Hope it may help some people looking for ideas.

After a certain amount of time, your access token expires.

To prevent this, you can request the 'offline_access' permission during the authentication, as noted here: Do Facebook Oauth 2.0 Access Tokens Expire?

Another way to make column aligned is as follows:

using namespace std;

cout.width(20); cout << left << "Artist";
cout.width(20); cout << left << "Title";
cout.width(10); cout << left << "Price";
...
cout.width(20); cout << left << artist;
cout.width(20); cout << left << title;
cout.width(10); cout << left << price;

We should estimate maximum length of values for each column. In this case, values of "Artist" column should not exceed 20 characters and so on.

I had a similar problem and google was sending me to this post. My solution was a bit different and less compact, but hopefully this can be useful to someone.

Showing your image with matplotlib.pyplot.imshow is generally a fast way to display 2D data. However this by default labels the axes with the pixel count. If the 2D data you are plotting corresponds to some uniform grid defined by arrays x and y, then you can use matplotlib.pyplot.xticks and matplotlib.pyplot.yticks to label the x and y axes using the values in those arrays. These will associate some labels, corresponding to the actual grid data, to the pixel counts on the axes. And doing this is much faster than using something like pcolor for example.

Here is an attempt at this with your data:

import matplotlib.pyplot as plt

# ... define 2D array hist as you did

plt.imshow(hist, cmap='Reds')
x = np.arange(80,122,2) # the grid to which your data corresponds
nx = x.shape[0]
no_labels = 7 # how many labels to see on axis x
step_x = int(nx / (no_labels - 1)) # step between consecutive labels
x_positions = np.arange(0,nx,step_x) # pixel count at label position
x_labels = x[::step_x] # labels you want to see
plt.xticks(x_positions, x_labels)
# in principle you can do the same for y, but it is not necessary in your case

Try to use:

mvn jacoco:report -debug

to see the details about your reporting process.

I configured my jacoco like this:

<configuration>
    <dataFile>~/jacoco.exec</dataFile>
    <outputDirectory>~/jacoco</outputDirectory>
</configuration>

Then mvn jacoco:report -debug shows it using the default configuration, which means jacoco.exec is not in ~/jacoco.exec. The error says missing execution data file.

So just use the default configuration:

<execution>
    <id>default-report</id>
    <goals>
    </goals>
    <configuration>
        <dataFile>${project.build.directory}/jacoco.exec</dataFile>
        <outputDirectory>${project.reporting.outputDirectory}/jacoco</outputDirectory>
    </configuration>
</execution>

And everything works fine.

If want to remove the word from only the start of the string, then you could do:

  string[string.startswith(prefix) and len(prefix):]  

Where string is your string variable and prefix is the prefix you want to remove from your string variable.

For example:

  >>> papa = "papa is a good man. papa is the best."  
  >>> prefix = 'papa'
  >>> papa[papa.startswith(prefix) and len(prefix):]
  ' is a good man. papa is the best.'

Try this :

select replace ( convert(varchar,getdate(),106),' ','/')

Don't use in-line JavaScript, separate your behaviour from your data and it gets much easier to handle. I'd suggest the following:

var table = document.getElementById('tableID'),
    cells = table.getElementsByTagName('td');

for (var i=0,len=cells.length; i<len; i++){
    cells[i].onclick = function(){
        console.log(this.innerHTML);
        /* if you know it's going to be numeric:
        console.log(parseInt(this.innerHTML),10);
        */
    }
}

var table = document.getElementById('tableID'),_x000D_
  cells = table.getElementsByTagName('td');_x000D_

JS Fiddle proof-of-concept.

A revised approach, in response to the comment (below):

You're missing a semicolon. Also, don't make functions within a loop.

This revision binds a (single) named function as the click event-handler of the multiple <td> elements, and avoids the unnecessary overhead of creating multiple anonymous functions within a loop (which is poor practice due to repetition and the impact on performance, due to memory usage):

function logText() {
  // 'this' is automatically passed to the named
  // function via the use of addEventListener()
  // (later):
  console.log(this.textContent);
}

// using a CSS Selector, with document.querySelectorAll()
// to get a NodeList of <td> elements within the #tableID element:
var cells = document.querySelectorAll('#tableID td');

// iterating over the array-like NodeList, using
// Array.prototype.forEach() and Function.prototype.call():
Array.prototype.forEach.call(cells, function(td) {
  // the first argument of the anonymous function (here: 'td')
  // is the element of the array over which we're iterating.

  // adding an event-handler (the function logText) to handle
  // the click events on the <td> elements:
  td.addEventListener('click', logText);
});

function logText() {_x000D_
  console.log(this.textContent);_x000D_
}_x000D_

To bind a UDP socket when receiving multicast means to specify an address and port from which to receive data (NOT a local interface, as is the case for TCP acceptor bind). The address specified in this case has a filtering role, i.e. the socket will only receive datagrams sent to that multicast address & port, no matter what groups are subsequently joined by the socket. This explains why when binding to INADDR_ANY (0.0.0.0) I received datagrams sent to my multicast group, whereas when binding to any of the local interfaces I did not receive anything, even though the datagrams were being sent on the network to which that interface corresponded.

Quoting from UNIX® Network Programming Volume 1, Third Edition: The Sockets Networking API by W.R Stevens. 21.10. Sending and Receiving

[...] We want the receiving socket to bind the multicast group and port, say 239.255.1.2 port 8888. (Recall that we could just bind the wildcard IP address and port 8888, but binding the multicast address prevents the socket from receiving any other datagrams that might arrive destined for port 8888.) We then want the receiving socket to join the multicast group. The sending socket will send datagrams to this same multicast address and port, say 239.255.1.2 port 8888.

Assuming your "states" collection is like:

{"name" : "Spain", "cities" : [ { "name" : "Madrid" }, { "name" : null } ] }
{"name" : "France" }

The query to find states with null cities would be:

db.states.find({"cities.name" : {"$eq" : null, "$exists" : true}});

It is a common mistake to query for nulls as:

db.states.find({"cities.name" : null});

because this query will return all documents lacking the key (in our example it will return Spain and France). So, unless you are sure the key is always present you must check that the key exists as in the first query.

Try it.

upd: after a minor adjustment I came up with this, so it works both ways now:

begin
  return utl_raw.cast_to_varchar2(utl_encode.base64_decode(utl_raw.cast_to_raw(t)));
end from_base64;

  substring        varchar2(2000);

  end from_base64;

begin

  select clobField into clobOriginal from clobTable where id = 1;

  while true loop

    /*we substract pieces of substring_length*/
    substring := dbms_lob.substr(clobOriginal,
                                 least(substring_length, substring_length * n + 1 - length(clobOriginal)),
                                 substring_length * n + 1);  
    /*if no substring is found  - then we've reached the end of blob*/

    if substring is null then
      exit;
    end if;  

    /*convert them to base64 encoding and stack it in new clob vadriable*/
    clobInBase64 := clobInBase64 || to_base64(substring);          
    n := n + 1;  

  end loop;

  n := 0;
  clobOriginal := null;

  /*then we do the very same thing backwards - decode base64*/
  while true loop 

    substring := dbms_lob.substr(clobInBase64,
                                 least(substring_length, substring_length * n + 1 - length(clobInBase64)),
                                 substring_length * n + 1);

    n := n + 1;  
  end loop; 

      /*and insert the data in our sample table - to ensure it's the same*/
  insert into clobTable (id, anotherClobField) values (1, clobOriginal);

end;

Which alignment technique you use depends on your circumstances but the basic one is float: right;:

<input type="button" value="Click Me" style="float: right;">

You'll probably want to clear your floats though but that can be done with overflow:hidden on the parent container or an explicit <div style="clear: both;"></div> at the bottom of the container.

For example: http://jsfiddle.net/ambiguous/8UvVg/

Floated elements are removed from the normal document flow so they can overflow their parent's boundary and mess up the parent's height, the clear:both CSS takes care of that (as does overflow:hidden). Play around with the JSFiddle example I added to see how floating and clearing behave (you'll want to drop the overflow:hidden first though).

We use:

/**
 * Get the customer's IP address.
 *
 * @return string
 */
public function getIpAddress() {
    if (!empty($_SERVER['HTTP_CLIENT_IP'])) {
        return $_SERVER['HTTP_CLIENT_IP'];
    } else if (!empty($_SERVER['HTTP_X_FORWARDED_FOR'])) {
        $ips = explode(',', $_SERVER['HTTP_X_FORWARDED_FOR']);
        return trim($ips[count($ips) - 1]);
    } else {
        return $_SERVER['REMOTE_ADDR'];
    }
}

The explode on HTTP_X_FORWARDED_FOR is because of weird issues we had detecting IP addresses when Squid was used.

Install Babun instead -> https://babun.github.io/index.html It contains Cygwin ;)

No. You have to make your own like this:

boolean tryParseInt(String value) {  
     try {  
         Integer.parseInt(value);  
         return true;  
      } catch (NumberFormatException e) {  
         return false;  
      }  
}

...and you can use it like this:

if (tryParseInt(input)) {  
   Integer.parseInt(input);  // We now know that it's safe to parse
}

EDIT (Based on the comment by @Erk)

Something like follows should be better

public int tryParse(String value, int defaultVal) {
    try {
        return Integer.parseInt(value);
    } catch (NumberFormatException e) {
        return defaultVal;
    }
}

When you overload this with a single string parameter method, it would be even better, which will enable using with the default value being optional.

public int tryParse(String value) {
    return tryParse(value, 0)
}

Normally, you add regular values to mySQL, from PHP like this:

function addValues($val1, $val2) {
    db_open(); // just some code ot open the DB 
    $query = "INSERT INTO uradmonitor (db_value1, db_value2) VALUES ('$val1', '$val2')";
    $result = mysql_query($query);
    db_close(); // just some code to close the DB
}

When your values are empty/null ($val1=="" or $val1==NULL), and you want NULL to be added to SQL and not 0 or empty string, to the following:

function addValues($val1, $val2) {
    db_open(); // just some code ot open the DB 
    $query = "INSERT INTO uradmonitor (db_value1, db_value2) VALUES (".
        (($val1=='')?"NULL":("'".$val1."'")) . ", ".
        (($val2=='')?"NULL":("'".$val2."'")) . 
        ")";
    $result = mysql_query($query);
    db_close(); // just some code to close the DB
}

Note that null must be added as "NULL" and not as "'NULL'" . The non-null values must be added as "'".$val1."'", etc.

Hope this helps, I just had to use this for some hardware data loggers, some of them collecting temperature and radiation, others only radiation. For those without the temperature sensor I needed NULL and not 0, for obvious reasons ( 0 is an accepted temperature value also).

You have to forgo the regex literal and use the object constructor, where you can pass the regex as a string.

var regex = new RegExp(pattern1+'|'+pattern2, 'gi');
str.match(regex);

var formatter = new Intl.NumberFormat("ru", {
  style: "currency",
  currency: "GBP"
});

alert( formatter.format(1234.5) ); // 1 234,5 £

What about using git branch -m to rename the master branch to another one, then rename seotweaks branch to master? Something like this:

git branch -m master old-master
git branch -m seotweaks master
git push -f origin master

This might remove commits in origin master, please check your origin master before running git push -f origin master.

Please try the following. It was successfully for me.

Steps:

1. Create a new emulator with this configuration:

2. Start the emulator and install the following APK files: GoogleLoginService.apk, GoogleServicesFramework.apk, and Phonesky.apk. You can do this with the following commands:

   3. Phonesky.apk AKA Google Play Store, v.3.5.16
   4. Google Maps, v.6.14.1
   5. Google Play services, v.2.0.10

3. Install Google Play services and Google Maps in the emulator

   adb install com.google.android.apps.maps-1.apk
   adb install com.google.android.gms-2.apk
   

4. Download Google Play Service revision 4 from this link and extra to folder sdkmanager->extra->google play service.
5. Import google-play-services_lib from androidsdk\extras\google\google_play_services.
6. Create a new project and reference the above project as a library project.
7. Run the project.

This is generic solution:

str.replaceAll("^.|.$", "")

You need to use %2.6f instead of %f in your printf statement

Use "attr" method in jquery.

$('.test').click(function(){
    var id = $(this).attr('id');
});

diff and then grep for the edit type you want.

diff -u A1 A2 | grep -E "^\+"

It has to do with how the function is called- basically the order in which things are put on the the stack and who is responsible for cleanup.

Here's the documentation, but it doesn't mean much unless you understand the first part:
http://msdn.microsoft.com/en-us/library/zxk0tw93.aspx

This is an old question and its been answered but I thought I'd put the --binary-files=text option here for anyone who wants to use it. The -I option ignores the binary file but if you want the grep to treat the binary file as a text file use --binary-files=text like so:

bash$ grep -i reset mediaLog*
Binary file mediaLog_dc1.txt matches
bash$ grep --binary-files=text -i reset mediaLog*
mediaLog_dc1.txt:2016-06-29 15:46:02,470 - Media [uploadChunk  ,315] - ERROR - ('Connection aborted.', error(104, 'Connection reset by peer'))
mediaLog_dc1.txt:ConnectionError: ('Connection aborted.', error(104, 'Connection reset by peer'))
bash$

Try to use the <link rel="icon" type="image/ico" href="images/favi.ico"/>

Based on my testing, the correct flag is "allowMultiQueries=true"

I've used Spring.NET in the past and had great success with it. I never noticed any substantial overhead with it, though the project we used it on was fairly heavy on its own. It only took a little time reading through the documentation to get it set up.

The first thing you should do is to determine whether you want to keep the local changes before you delete the commit message.

Use git log to show current commit messages, then find the commit_id before the commit that you want to delete, not the commit you want to delete.

If you want to keep the locally changed files, and just delete commit message:

git reset --soft commit_id

If you want to delete all locally changed files and the commit message:

git reset --hard commit_id

That's the difference of soft and hard

If using ES2016 you can use async and await and do something like:

(async () => {
  const data = await fetch(url)
  myFunc(data)
}())

If using ES2015 you can use Generators. If you don't like the syntax you can abstract it away using an async utility function as explained here.

If using ES5 you'll probably want a library like Bluebird to give you more control.

Finally, if your runtime supports ES2015 already execution order may be preserved with parallelism using Fetch Injection.

You can use the sp_MSforeachtable stored procedure like so:

USE MyDatabase
EXEC sp_MSforeachtable 'TRUNCATE TABLE ?'

Be warned that this will delete (by truncation) ALL data from all user tables. And in case you can't TRUNCATE due to foreign keys etc. you can run the same as a delete:

USE MyDatabase
EXEC sp_MSforeachtable 'DELETE FROM ?'

Process of generating RPM from source file:

1. download source file with.gz extention.
2. install rpm-build and rpmdevtools from yum install. (rpmbuild folder will be generated...SPECS,SOURCES,RPMS.. folders will should be generated inside the rpmbuild folder).
3. copy the source code.gz to SOURCES folder.(rpmbuild/SOURCES)
4. Untar the tar ball by using the following command. go to SOURCES folder :rpmbuild/SOURCES where tar file is present. command: e.g tar -xvzf httpd-2.22.tar.gz httpd-2.22 folder will be generated in the same path.
5. go to extracted folder and then type below command: ./configure --prefix=/usr/local/apache2 --with-included-apr --enable-proxy --enable-proxy-balancer --with-mpm=worker --enable-mods-static=all (.configure may vary according to source for which RPM has to built-- i have done for apache HTTPD which needs apr and apr-util dependency package).
6. run below command once the configure is successful: make
7. after successfull execution od make command run: checkinstall in tha same folder. (if you dont have checkinstall software please download latest version from site) Also checkinstall software has bug which can be solved by following way::::: locate checkinstallrc and then replace TRANSLATE = 1 to TRANSLATE=0 using vim command. Also check for exclude package: EXCLUDE="/selinux"
8. checkinstall will ask for option (type R if you want tp build rpm for source file)
9. Done .rpm file will be built in RPMS folder inside rpmbuild/RPMS file... ALL the BEST ....

An answer that is not limited to the OP's case

The title of the question leads people here, so I decided to answer that question for everyone else since the OP's described case was so limited.

TL;DR

I finally settled on writing a function.

1. If you want 0 in case of non-int:

int(){ printf '%d' ${1:-} 2>/dev/null || :; }

2. If you want [empty_string] in case of non-int:

int(){ expr 0 + ${1:-} 2>/dev/null||:; }

3. If you want find the first int or [empty_string]:

int(){ expr ${1:-} : '[^0-9]*\([0-9]*\)' 2>/dev/null||:; }

4. If you want find the first int or 0:

# This is a combination of numbers 1 and 2
int(){ expr ${1:-} : '[^0-9]*\([0-9]*\)' 2>/dev/null||:; }

If you want to get a non-zero status code on non-int, remove the ||: (aka or true) but leave the ;

Tests

# Wrapped in parens to call a subprocess and not `set` options in the main bash process
# In other words, you can literally copy-paste this code block into your shell to test
( set -eu;
    tests=( 4 "5" "6foo" "bar7" "foo8.9bar" "baz" " " "" )
    test(){ echo; type int; for test in "${tests[@]}"; do echo "got '$(int $test)' from '$test'"; done; echo "got '$(int)' with no argument"; }

    int(){ printf '%d' ${1:-} 2>/dev/null||:; };
    test

    int(){ expr 0 + ${1:-} 2>/dev/null||:; }
    test

    int(){ expr ${1:-} : '[^0-9]*\([0-9]*\)' 2>/dev/null||:; }
    test

    int(){ printf '%d' $(expr ${1:-} : '[^0-9]*\([0-9]*\)' 2>/dev/null)||:; }
    test

    # unexpected inconsistent results from `bc`
    int(){ bc<<<"${1:-}" 2>/dev/null||:; }
    test
)

Note

I got sent down this rabbit hole because the accepted answer is not compatible with set -o nounset (aka set -u)

# This works
$ ( number="3"; string="foo"; echo $((number)) $((string)); )
3 0

# This doesn't
$ ( set -u; number="3"; string="foo"; echo $((number)) $((string)); )
-bash: foo: unbound variable

ES6 of the day here;

const json_getAllKeys = data => (
  data.reduce((keys, obj) => (
    keys.concat(Object.keys(obj).filter(key => (
      keys.indexOf(key) === -1))
    )
  ), [])
)

And yes it can be written in very long one line;

const json_getAllKeys = data => data.reduce((keys, obj) => keys.concat(Object.keys(obj).filter(key => keys.indexOf(key) === -1)), [])

EDIT: Returns all first order keys if the input is of type array of objects

The updating of the password in the windows credential manager was not the solution for me.

I had to set a different remote url, by:

git remote set-url origin https://gitlab....git

The url in this case was the one that could be found in Gitlab under Clone -> Clone with HTTPS. It was not the one in the command line instructions.

With ECMAScript 6, you can use variable property names with the object literal syntax, like this:

var keyName = 'myKey';
var obj = {
              [keyName]: 1
          };
obj.myKey;//1

This syntax is available in the following newer browsers:

Edge 12+ (No IE support), FF34+, Chrome 44+, Opera 31+, Safari 7.1+

(https://kangax.github.io/compat-table/es6/)

You can add support to older browsers by using a transpiler such as babel. It is easy to transpile an entire project if you are using a module bundler such as rollup or webpack.

Most portably...

#include <limits>

using std::numeric_limits;

    ...
    cout.precision(numeric_limits<double>::digits10 + 1);
    cout << d;

This difference is due to the behavior of Promises more than fetch() specifically.

When a .then() callback returns an additional Promise, the next .then() callback in the chain is essentially bound to that Promise, receiving its resolve or reject fulfillment and value.

The 2nd snippet could also have been written as:

iterator.then(response =>
    response.json().then(post => document.write(post.title))
);

In both this form and yours, the value of post is provided by the Promise returned from response.json().

When you return a plain Object, though, .then() considers that a successful result and resolves itself immediately, similar to:

iterator.then(response =>
    Promise.resolve({
      data: response.json(),
      status: response.status
    })
    .then(post => document.write(post.data))
);

post in this case is simply the Object you created, which holds a Promise in its data property. The wait for that promise to be fulfilled is still incomplete.

Leaving here a quick alternative, using class toggle on a table. The behavior is very similar than a select, but can be styled with transition, filters and colors, each children individually.

function toggleSelect(){ _x000D_
 if (store.classList[0] === "hidden"){_x000D_
    store.classList = "viewfull"_x000D_
  }_x000D_
  else {_x000D_
    store.classList = "hidden"_x000D_
  }_x000D_
}

You can try the following:

remove_column :table_name, :column_name

(Official documentation)

You can use the WinSPC program. Its access to any server is pretty easy. The program gives its guide too. I hope it's helpfull.

This solves the problem of releasing the memory for me!!!

import gc
import pandas as pd

del [[df_1,df_2]]
gc.collect()
df_1=pd.DataFrame()
df_2=pd.DataFrame()

the data-frame will be explicitly set to null

in the above statements

Firstly, the self reference of the dataframe is deleted meaning the dataframe is no longer available to python there after all the references of the dataframe is collected by garbage collector (gc.collect()) and then explicitly set all the references to empty dataframe.

more on the working of garbage collector is well explained in https://stackify.com/python-garbage-collection/

Use built-in Exception Handling Middleware

Step 1. In your startup, register your exception handling route:

// It should be one of your very first registrations
app.UseExceptionHandler("/error"); // Add this
app.UseEndpoints(endpoints => endpoints.MapControllers());

Step 2. Create controller that will handle all exceptions and produce error response:

[ApiExplorerSettings(IgnoreApi = true)]
public class ErrorsController : ControllerBase
{
    [Route("error")]
    public MyErrorResponse Error()
    {
        var context = HttpContext.Features.Get<IExceptionHandlerFeature>();
        var exception = context.Error; // Your exception
        var code = 500; // Internal Server Error by default

        if      (exception is MyNotFoundException) code = 404; // Not Found
        else if (exception is MyUnauthException)   code = 401; // Unauthorized
        else if (exception is MyException)         code = 400; // Bad Request

        Response.StatusCode = code; // You can use HttpStatusCode enum instead

        return new MyErrorResponse(exception); // Your error model
    }
}

A few important notes and observations:

• [ApiExplorerSettings(IgnoreApi = true)] is needed. Otherwise, it may break your Swashbuckle swagger
• Again, app.UseExceptionHandler("/error"); has to be one of the very top registrations in your Startup Configure(...) method. It's probably safe to place it at the top of the method.
• The path in app.UseExceptionHandler("/error") and in controller [Route("error")] should be the same, to allow the controller handle exceptions redirected from exception handler middleware.

Microsoft documentation for this subject is not that great but has some interesting ideas. I'll just leave the link here.

Response models and custom exceptions

Implement your own response model and exceptions. This example is just a good starting point. Every service would need to handle exceptions in its own way. But with this code, you have full flexibility and control over handling exceptions and returning a proper result to the caller.

An example of error response model (just to give you some ideas):

public class MyErrorResponse
{
    public string Type { get; set; }
    public string Message { get; set; }
    public string StackTrace { get; set; }

    public MyErrorResponse(Exception ex)
    {
        Type = ex.GetType().Name;
        Message = ex.Message;
        StackTrace = ex.ToString();
    }
}

For simpler services, you might want to implement http status code exception that would look like this:

public class HttpStatusException : Exception
{
    public HttpStatusCode Status { get; private set; }

    public HttpStatusException(HttpStatusCode status, string msg) : base(msg)
    {
        Status = status;
    }
}

This can be thrown like that:

throw new HttpStatusCodeException(HttpStatusCode.NotFound, "User not found");

Then your handling code could be simplified to:

if (exception is HttpStatusException httpException)
{
    code = (int) httpException.Status;
}

Why so un-obvious HttpContext.Features.Get<IExceptionHandlerFeature>()?

ASP.NET Core developers embraced the concept of middlewares where different aspects of functionality such as Auth, Mvc, Swagger etc. are separated and executed sequentially by processing the request and returning the response or passing the execution to the next middleware. With this architecture, MVC itself, for instance, would not be able to handle errors happening in Auth. So, they came up with exception handling middleware that catches all the exceptions happening in middlewares registered down in the pipeline, pushes exception data into HttpContext.Features, and re-runs the pipeline for specified route (/error), allowing any middleware to handle this exception, and the best way to handle it is by our Controllers to maintain proper content negotiation.

C# Thread.Abort is NOT guaranteed to abort the thread instantaneously. It will probably work when a thread calls Abort on itself but not when a thread calls on another.

Please refer to the documentation: http://msdn.microsoft.com/en-us/library/ty8d3wta.aspx

I have faced this problem writing tools that interact with hardware - you want immediate stop but it is not guaranteed. I typically use some flags or other such logic to prevent execution of parts of code running on a thread (and which I do not want to be executed on abort - tricky).

You would probably use your example like this

var newText = "<span>" + $("p").text().split(" ").join("</span> <span>") + "</span>";

This will put span tags around all the words in you paragraphs, turning

<p>Test is a demo.</p>

into

<p><span>Test</span> <span>is</span> <span>a</span> <span>demo.</span></p>

I do not know what the practical use of this could be.

Execute the below code if you want to update all record in all columns:

update config set column1='value',column2='value'...columnN='value';

and if you want to update all columns of a particular row then execute below code:

update config set column1='value',column2='value'...columnN='value' where column1='value'

Try this coding:

LocationManager locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
Criteria criteria = new Criteria();

Location location = locationManager.getLastKnownLocation(locationManager.getBestProvider(criteria, false));
if (location != null)
{
    map.animateCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(location.getLatitude(), location.getLongitude()), 13));

    CameraPosition cameraPosition = new CameraPosition.Builder()
        .target(new LatLng(location.getLatitude(), location.getLongitude()))      // Sets the center of the map to location user
        .zoom(17)                   // Sets the zoom
        .bearing(90)                // Sets the orientation of the camera to east
        .tilt(40)                   // Sets the tilt of the camera to 30 degrees
        .build();                   // Creates a CameraPosition from the builder
    map.animateCamera(CameraUpdateFactory.newCameraPosition(cameraPosition));       
}

You can append a queryString to your src and change it only when you will release an updated version:

<script src="test.js?v=1"></script>

In this way the browser will use the cached version until a new version will be specified (v=2, v=3...)

Off the top of my head:

$('#content').height(
    $(window).height() - $('#header').height() - $('#footer').height()
);

Is that what you mean?

My case: Seeing the same INFO message.

Centos 6.2 x86_64 Tomcat 6.0.24

This fixed the problem for me:

yum install tomcat-native

boom!

Try:

git push --all origin

Updating a Specific Library - scikit-learn:

Anaconda (conda):

conda install scikit-learn

Pip Installs Packages (pip):

pip install --upgrade scikit-learn

Verify Update:

conda list scikit-learn

It should now display the current (and desired) version of the scikit-learn library.

For me personally, I tried using the conda command to update the scikit-learn library and it acted as if it were installing the latest version to then later discover (with an execution of the conda list scikit-learn command) that it was the same version as previously and never updated (or recognized the update?). When I used the pip command, it worked like a charm and correctly updated the scikit-learn library to the latest version!

Hope this helps!

More in-depth details of latest version can be found here (be mindful this applies to the scikit-learn library version of 0.22):

• Release Highlights for scikit-learn 0.22

If you aren't interested in specifying a time, you can also use the format 'DD/MM/YYYY', however I would stick to a Conversion method, and its relevant ISO format, as you really should avoid using default values.

Here's an example:

SET startDate = CONVERT(datetime,'2015-03-11T23:59:59.000',126) WHERE custID = 'F24'

There’s a new HTML5 approach to this, the formaction attribute:

<button type="submit" formaction="/action_one">First action</button>
<button type="submit" formaction="/action_two">Second action</button>

Apparently this does not work in IE9 and earlier, but for other browsers you should be fine (see: w3schools.com HTML <button> formaction Attribute).

Personally, I generally use Javascript to submit forms remotely (for faster perceived feedback) with this approach as backup. Between the two, the only people not covered are IE<9 with Javascript disabled.

Of course, this may be inappropriate if you’re basically taking the same action server-side regardless of which button was pushed, but often if there are two user-side actions available then they will map to two server-side actions as well.

Edit: As noted by Pascal_dher in the comments, this attribute is also available on the <input> tag as well.

It's fatal. The remote server has sent you a RST packet, which indicates an immediate dropping of the connection, rather than the usual handshake. This bypasses the normal half-closed state transition. I like this description:

"Connection reset by peer" is the TCP/IP equivalent of slamming the phone back on the hook. It's more polite than merely not replying, leaving one hanging. But it's not the FIN-ACK expected of the truly polite TCP/IP converseur.

If you have sklearn isntalled, a simple alternative is to use sklearn.metrics.auc

This computes the area under the curve using the trapezoidal rule given arbitrary x, and y array

import numpy as np
from sklearn.metrics import auc

dx = 5
xx = np.arange(1,100,dx)
yy = np.arange(1,100,dx)

print('computed AUC using sklearn.metrics.auc: {}'.format(auc(xx,yy)))
print('computed AUC using np.trapz: {}'.format(np.trapz(yy, dx = dx)))

both output the same area: 4607.5

the advantage of sklearn.metrics.auc is that it can accept arbitrarily-spaced 'x' array, just make sure it is ascending otherwise the results will be incorrect

Current date is in yyyy-mm-dd format. You can convert it into yyyymmdd format using substring function:

select substr(current date,1,4)||substr(current date,6,2)||substr(currentdate,9,2)

The simplest way to fill the shape with the Radius is:

XML:

<TextView
    android:id="@+id/textView"
    android:background="@drawable/test"
    android:layout_height="45dp"
    android:layout_width="100dp"
    android:text="Moderate"/>

Java:

(textView.getBackground()).setColorFilter(Color.parseColor("#FFDE03"), PorterDuff.Mode.SRC_IN);
