[bash:~] $ sudo update-alternatives --install /usr/local/bin/python python \

e.g. installing into /usr/local/bin instead of /usr/bin.

and ensure the /usr/local/bin is before /usr/bin in PATH.

i.e.

[bash:~] $ echo $PATH
/usr/local/bin:/usr/bin:/bin

Ensure this always is the case by adding

export PATH=/usr/local/bin:$PATH

to the end of your ~/.bashrc file. Prefixing the PATH environment variable with custom bin folder such as /usr/local/bin or /opt/<some install>/bin is generally recommended to ensure that customizations are found before the default system ones.

The answer here is to find all descendent children, which has an answer here:

docker how can I get the list of dependent child images?

Then use that to remove the child images in order.

Try to install your application by using yum command yum install application_name

It seems that ARM64 was created by Apple and AARCH64 by the others, most notably GNU/GCC guys.

After some googling I found this link:

The LLVM 64-bit ARM64/AArch64 Back-Ends Have Merged

So it makes sense, iPad calls itself ARM64, as Apple is using LLVM, and Edge uses AARCH64, as Android is using GNU GCC toolchain.

check if tun/tap enabled:

cat /dev/net/tun

if ok will see something :

cat: /dev/net/tun: File descriptor in bad state

$pwd /usr/lib/jvm/jre1.8.0_25/bin

./jcontrol

as follow,

java Control Panel --> Security --> Edit Site list ,
then apply, and ok.

I verified permissions but all was good (mongod:mongod). As I'm working on a large project and from a similar issue in our dev environment where we had a script consuming all available disk space, I could see in the error messages that mongod needs at least 3.7Gb free disk space to run..

I checked my own disk space only to see that less than 2Gb was remaining. After moving / erasing some data I can successfully start mongod again.

Hope this helps ;-)

I had similar issue, the actual reason was that there was mongod session running already from my previous attempt.

I ran

killall mongod

and everything else ran just as expected.

killall command would send a TERM signal to all processes with a real UID. So this kills all the running instances of mongod so that you could start your own.

Just run mongod --repair from C:\Program Files\MongoDB\Server\4.0\bin

Here is the doc https://docs.mongodb.com/manual/tutorial/recover-data-following-unexpected-shutdown/

You can also try this:

ini_set("max_execution_time", "-1");
ini_set("memory_limit", "-1");
ignore_user_abort(true);
set_time_limit(0);

Enable all these from php.ini configuration file

Fedora users WILL NOT be able to do a simple "yum install nodejs" due to serious naming and file placement conflicts that prevent this package from even being available through the Fedora repositories.

There is apparently at least one alternate repository available with an alternate build that may work, but that's two too many "alternates" for me to be willing to use it-- I'm looking for another alternative.

For Debian. Required packages are: m4 automake pkg-config libtool

I modified "Jannich Brendle" version to 1000 instead 500. And list the result of euler12.bin, euler12.erl, p12dist.erl. Both erl codes use '+native' to compile.

You need to find the bin folder and then open a command prompt on that folder Then just type mongo.exe and press enter to start the shell

Or you can supply the full path to mongo.exe from any folder to start the shell:

c:\MongoDB\bin\mongo.exe

Then if you have multiple databases, you can do enter command >use <database_name> to use that db

Let me know if it helps or have issues

OS X. Activity Monitor, look for mongod, cross it . then run again mongod. problem Solved.

It can happen because of native method calling in your application. For example, in Qtjambi if you use QApplication.quit() instead of QApplication.closeAllWindows() for closing a Java application it generates an error log.

In this case, you can get a stack trace right to your method that called the native code and caused the crash. Just look in the log file it tells you about:

# An error report file with more information is saved as hs_err_pid24139.log.

The stack trace looks quite unusual, since it has native code mixed with VM code and your code, but each line is prefixed so you can tell which lines are your own code. There's a key at the top of the stack trace to explain the prefixes:

Native frames: (J=compiled Java code, A=aot compiled Java code, j=interpreted, Vv=VM code, C=native code)

Correct, closing the shell will stop MongoDB. Try using the --fork command line arg for the mongod process which makes it run as a daemon instead. I'm no Unix guru, but I'm sure there must be a way to then get it to auto start when the machine boots up.

e.g.

mongod --fork --logpath /var/log/mongodb.log --logappend

Check out the full documentation on Starting and Stopping Mongo.

There should be svn utility on you box, if installed:

$ svn checkout http://example.com/svn/somerepo somerepo

This will check out a working copy from a specified repository to a directory somerepo on our file system.

You may want to print commands, supported by this utility:

$ svn help

uname -a output in your question is identical to one, used by Parallels Virtuozzo Containers for Linux 4.0 kernel, which is based on Red Hat 5 kernel, thus your friends are rpm or the following command:

$ sudo yum install subversion

Isn't this the normal way to free the memory associated with an object?

This is a common way of managing dynamically allocated memory, but it's not a good way to do so. This sort of code is brittle because it is not exception-safe: if an exception is thrown between when you create the object and when you delete it, you will leak that object.

It is far better to use a smart pointer container, which you can use to get scope-bound resource management (it's more commonly called resource acquisition is initialization, or RAII).

As an example of automatic resource management:

void test()
{
    std::auto_ptr<Object1> obj1(new Object1);

} // The object is automatically deleted when the scope ends.

Depending on your use case, auto_ptr might not provide the semantics you need. In that case, you can consider using shared_ptr.

As for why your program crashes when you delete the object, you have not given sufficient code for anyone to be able to answer that question with any certainty.

Apache is not running

It could also be something as simple as Apache not being configured to start automatically on boot. Assuming you are on a Red Hat-like system such as CentOS or Fedora, the chkconfig –list command will show you which services are set to start for each runlevel. You should see a line like

    httpd           0:off   1:off   2:on    3:on    4:on    5:on    6:off

If instead it says "off" all the way across, you can activate it with chkconfig httpd on. OR you can start apache manually from your panel.

Option 1a: While loop: Single line at a time: Input redirection

#!/bin/bash
filename='peptides.txt'
echo Start
while read p; do 
    echo $p
done < $filename

Option 1b: While loop: Single line at a time:
Open the file, read from a file descriptor (in this case file descriptor #4).

#!/bin/bash
filename='peptides.txt'
exec 4<$filename
echo Start
while read -u4 p ; do
    echo $p
done

If someone is having trouble with installing php-mbstring package in ubuntu do following sudo apt-get install libapache2-mod-php5

What is the JVM used ? I know that BEA JRockit does not exceed 1850mB for max heap size. It does not fail but warns the user that it will not use more than 1850mB.

I don't know why there is such a limit but I know it exists for BEA JRockit.

Best regards.

If you have a 64-bit OS, instead of i686, you have x86_64 or ia64 in the output of uname -a. In that you do not have any of these two strings; you have a 32-bit OS (note that this does not mean that your CPU is not 64-bit).

Try this:

<!DOCTYPE html>
<html>

    <body>
        <p>Add Section</p>

        <label>First Number:</label>
        <input id="txt1"  type="text"/><br />
        <label>Second Number:</label>
        <input id="txt2"  type="text"/><br />

        <input type="button" name="Add" value="Add" onclick="addTwoNumber()"/>
        <p id="demo"></p>

        <script>
            function myFunction() {
                document.getElementById("demo").innerHTML = Date();
            }

            function addTwoNumber(){
                var a = document.getElementById("txt1").value;
                var b = document.getElementById("txt2").value;

                var x = Number(a) + Number(b);
                document.getElementById("demo").innerHTML = "Add Value: " + x;
            }
        </script>
    </body>
</html>

Bit less elegant but can also do:

sl[len(sl)-1: len(sl)]

If we want partial match just like contains, we can chain the contain call like this :

def getSelectedTablesRows2(allTablesInfoDF: DataFrame, tableNames: Seq[String]): DataFrame = {

    val tableFilters = tableNames.map(_.toLowerCase()).map(name => lower(col("table_name")).contains(name))
    val finalFilter = tableFilters.fold(lit(false))((accu, newTableFilter) => accu or newTableFilter)
    allTablesInfoDF.where(finalFilter)

  }

>>> myList = [10,20,30,40,50,60,70,80,90]
>>> myInt = 10
>>> newList = map(lambda x: x/myInt, myList)
>>> newList
[1, 2, 3, 4, 5, 6, 7, 8, 9]

Can't hurt to post another view since there's still not an official way to do this. Wrote a lightweight jQuery plugin with which you can define a background radial gradient and a transition speed. This basic usage will then let it fade in, optimised with requestAnimationFrame (very smooth) :

$('#element').gradientFade({

    duration: 2000,
    from: '(20,20,20,1)',
    to: '(120,120,120,0)'
});

http://codepen.io/Shikkediel/pen/xbRaZz?editors=001

Keeps original background and all properties intact. Also has highlight tracking as a setting :

http://codepen.io/Shikkediel/pen/VYRZZY?editors=001

Developers often do:

Set<String> set = new HashSet<String>(Arrays.asList(arr));
return set.contains(targetValue);

The above code works, but there is no need to convert a list to set first. Converting a list to a set requires extra time. It can as simple as:

Arrays.asList(arr).contains(targetValue);

or

   for(String s: arr){
        if(s.equals(targetValue))
            return true;
    }

return false;

The first one is more readable than the second one.

Simply try something like

Arrays.asList(array)

If you have installed openssl, you can use:

echo -n "foobar" | openssl dgst -sha256

For other algorithms you can replace -sha256 with -md4, -md5, -ripemd160, -sha, -sha1, -sha224, -sha384, -sha512 or -whirlpool.

Don't expect sprintf (or any other function with varargs) to automatically cast anything. The compiler doesn't try to read the format string and do the cast for you; at runtime, sprintf has no meta-information available to determine what is on the stack; it just pops bytes and interprets them as given by the format string. sprintf(myvar, "%0", 0); immediately segfaults.

So: The format strings and the other arguments must match!

I read a csv with two columns from bucket s3, and the content of the file csv i put in pandas dataframe.

Example:

,
"s3":{

Yes, since it's a dynamically type language ;)

Read this for reference: PEP 257

The code says everything:

max@serv$ chmod 777 .

Okay, it doesn't say everything.

In UNIX and Linux, the ability to remove a file is not determined by the access bits of that file. It is determined by the access bits of the directory which contains the file.

Think of it this way -- deleting a file doesn't modify that file. You aren't writing to the file, so why should "w" on the file matter? Deleting a file requires editing the directory that points to the file, so you need "w" on the that directory.

E = exponent expression, simply means power(10, n) or 10 ^ n

F = fraction expression, default 6 digits precision

G = gerneral expression, somehow smart to show the number in a concise way (but really?)

See the below example,

The code

void main(int argc, char* argv[])  
{  
        double a = 4.5;
        printf("=>>>> below is the example for printf 4.5\n");
        printf("%%e %e\n",a);
        printf("%%f %f\n",a);
        printf("%%g %g\n",a);
        printf("%%E %E\n",a);
        printf("%%F %F\n",a);
        printf("%%G %G\n",a);
          
        double b = 1.79e308;
        printf("=>>>> below is the exbmple for printf 1.79*10^308\n");
        printf("%%e %e\n",b);
        printf("%%f %f\n",b);
        printf("%%g %g\n",b);
        printf("%%E %E\n",b);
        printf("%%F %F\n",b);
        printf("%%G %G\n",b);

        double d = 2.25074e-308;
        printf("=>>>> below is the example for printf 2.25074*10^-308\n");
        printf("%%e %e\n",d);
        printf("%%f %f\n",d);
        printf("%%g %g\n",d);
        printf("%%E %E\n",d);

I'm not aware of anything in the Python standard library (or elsewhere) that implements Dawson's AlmostEqual2sComplement function. If that's the sort of behaviour you want, you'll have to implement it yourself. (In which case, rather than using Dawson's clever bitwise hacks you'd probably do better to use more conventional tests of the form if abs(a-b) <= eps1*(abs(a)+abs(b)) + eps2 or similar. To get Dawson-like behaviour you might say something like if abs(a-b) <= eps*max(EPS,abs(a),abs(b)) for some small fixed EPS; this isn't exactly the same as Dawson, but it's similar in spirit.

You can do that using Python 2.

1. Remove request
2. Make that line: from urllib2 import urlopen

You cannot have request in Python 2, you need to have Python 3 or above.

 Bitmap yourBitmap;
 Bitmap resized = Bitmap.createScaledBitmap(yourBitmap, newWidth, newHeight, true);

or:

 resized = Bitmap.createScaledBitmap(yourBitmap,(int)(yourBitmap.getWidth()*0.8), (int)(yourBitmap.getHeight()*0.8), true);

This also could be easiest way to add items in ListBox.

for (int i = 0; i < MyList.Count; i++)
{
        listBox1.Items.Add(MyList.ElementAt(i));
}

Further improvisation of this code can add items at runtime.

If you want to use the new android.support.v7.app.AlertDialog and have different colors for the buttons and also have a custom layout then have a look at my https://gist.github.com/JoachimR/6bfbc175d5c8116d411e

@NonNull
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {

    View v = inflater.inflate(R.layout.custom_layout, null);

    initDialogUi(v);

    final AlertDialog d = new AlertDialog.Builder(activity, R.style.AppCompatAlertDialogStyle)
            .setTitle(getString(R.string.some_dialog_title))
            .setCancelable(true)
            .setPositiveButton(activity.getString(R.string.some_dialog_title_btn_positive),
                    new DialogInterface.OnClickListener() {
                        @Override
                        public void onClick(DialogInterface dialog, int which) {
                            doSomething();
                            dismiss();
                        }
                    })
            .setNegativeButton(activity.getString(R.string.some_dialog_title_btn_negative),
                    new DialogInterface.OnClickListener() {
                        @Override
                        public void onClick(DialogInterface dialog, int which) {
                            dismiss();
                        }
                    })
            .setView(v)
            .create();

    // change color of positive button         
    d.setOnShowListener(new DialogInterface.OnShowListener() {
        @Override
        public void onShow(DialogInterface dialog) {
            Button b = d.getButton(DialogInterface.BUTTON_POSITIVE);
            b.setTextColor(getResources().getColor(R.color.colorPrimary));
        }
    });

    return d;
}

Try:

 Expanded(
  child: Container(
      child: Text('OVER FLOW TEST TEXTTTT',
          overflow: TextOverflow.fade)),
),

This will show OVER FLOW. If there is an overflow, it will be handled.

Dependency Management allows to consolidate and centralize the management of dependency versions without adding dependencies which are inherited by all children. This is especially useful when you have a set of projects (i.e. more than one) that inherits a common parent.

Another extremely important use case of dependencyManagement is the control of versions of artifacts used in transitive dependencies. This is hard to explain without an example. Luckily, this is illustrated in the documentation.

from a Debug Keystore we can get the SHA1 value in Eclipse. Accessing from the menu: Window -> Preferences -> Android -> Build

but it doesn´t work for a production Keystore.

So, to get the SHA1 value from a production Keystore go to: Android Tools -> Export Signed Application Package. Follow the process for signing your apk and the SHA1 will showed as a certificate.

Pass it in through the constructor:

const char* dat = "my string!";
std::string my_string( dat );

You can use the function string.c_str() to go the other way:

std::string my_string("testing!");
const char* dat = my_string.c_str();

To print your context ,you can write code like this :

FILE *fp;
char *of;
sprintf(of,"%s%s",text1,text2);
fp=fopen(of,'w');
fprintf(fp,"your print line");

Just added to mrjandro's solution a quick hack to get rid of simple connection errors / timeouts.

You can adjust the threshold changing max_error_count variable value and add notifications of any sort.

import socket

max_error_count = 10

def increase_error_count():
    # Quick hack to handle false Port not open errors 
    with open('ErrorCount.log') as f:
        for line in f:
            error_count = line
    error_count = int(error_count)
    print "Error counter: " + str(error_count)
    file = open('ErrorCount.log', 'w')
    file.write(str(error_count + 1))
    file.close()
    if error_count == max_error_count:
        # Send email, pushover, slack or do any other fancy stuff
        print "Sending out notification"
        # Reset error counter so it won't flood you with notifications
        file = open('ErrorCount.log', 'w')
        file.write('0')
        file.close()

sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.settimeout(2) 
result = sock.connect_ex(('127.0.0.1',80))
if result == 0:
        print "Port is open"
else:
        print "Port is not open"
        increase_error_count()

And here you find a Python 3 compatible version (just fixed print syntax):

import socket

max_error_count = 10

def increase_error_count():
    # Quick hack to handle false Port not open errors
    with open('ErrorCount.log') as f:
        for line in f:
            error_count = line
    error_count = int(error_count)
    print ("Error counter: " + str(error_count))
    file = open('ErrorCount.log', 'w')
    file.write(str(error_count + 1))
    file.close()
    if error_count == max_error_count:
        # Send email, pushover, slack or do any other fancy stuff
        print ("Sending out notification")
        # Reset error counter so it won't flood you with notifications
        file = open('ErrorCount.log', 'w')
        file.write('0')
        file.close()

sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.settimeout(2) 
result = sock.connect_ex(('127.0.0.1',80))
if result == 0:
        print ("Port is open")
else:
        print ("Port is not open")
        increase_error_count()

For me it was changing the Android API level to one with Google APIs

Thanks to everyone for responding so fast. Joel, I used your option 2 and added a registry key to the "Run" folder of the current user. Here's the code I used for anyone else who's interested.

    using Microsoft.Win32;
    private void SetStartup()
    {
        RegistryKey rk = Registry.CurrentUser.OpenSubKey
            ("SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run", true);

        if (chkStartUp.Checked)
            rk.SetValue(AppName, Application.ExecutablePath);
        else
            rk.DeleteValue(AppName,false);            

    }

Expanding on @gecco 's answer, the following is an example that'll show you the difference:

def foo(**kwargs):
    for entry in kwargs.items():
        print("Key: {}, value: {}".format(entry[0], entry[1]))

# call using normal keys:
foo(a=1, b=2, c=3)
# call using an unpacked dictionary:
foo(**{"a": 1, "b":2, "c":3})

# call using a dictionary fails because the function will think you are
# giving it a positional argument
foo({"a": 1, "b": 2, "c": 3})
# this yields the same error as any other positional argument
foo(3)
foo("string")

Here you can see how unpacking a dictionary works, and why sending an actual dictionary fails

That won't work if the string contains more than one match... try this:

echo "/x/y/z/x" | awk '{ gsub("/", "_") ; system( "echo "  $0) }'

or better (if the echo isn't a placeholder for something else):

echo "/x/y/z/x" | awk '{ gsub("/", "_") ; print $0 }'

In your case you want to make a copy of the value before changing it:

echo "/x/y/z/x" | awk '{ c=$0; gsub("/", "_", c) ; system( "echo " $0 " " c )}'

The correct SQL connection string for SQL with specify port is use comma between ip address and port number like following pattern: xxx.xxx.xxx.xxx,yyyy

Best way to find out is to record the macro and perform the exact steps and see what VBA code it generates. you can then go and replace the bits you want to make generic (i.e. file names and stuff)

Do this:

 $( '#wrapper' ).on( 'click', 'a', function () { ... });

where #wrapper is a static element in which you add the dynamic links.

So, you have a wrapper which is hard-coded into the HTML source code:

<div id="wrapper"></div>

and you fill it with dynamic content. The idea is to delegate the events to that wrapper, instead of binding handlers directly on the dynamic elements.

Btw, I recommend Backbone.js - it gives structure to this process:

var YourThing = Backbone.View.extend({

    // the static wrapper (the root for event delegation)
    el: $( '#wrapper' ),

    // event bindings are defined here 
    events: {
        'click a': 'anchorClicked'
    },

    // your DOM event handlers
    anchorClicked: function () {
        // handle click event 
    }

});

new YourThing; // initializing your thing

You can make use of the React.createClone method. Create your element, than create a clone of it. During the clone's creation, you can inject props. Inject an onClick : method prop like this

{ onClick : () => this.changeColor(originalElement, index) }

the changeColor method will set the state with the duplicate, allowing you sto set the color in the process.

render()_x000D_
  {_x000D_
    return(_x000D_
      <ul>_x000D_
_x000D_
        {this.state.items.map((val, ind) => {_x000D_
          let item = <li key={ind}>{val}</li>;_x000D_
          let props = { _x000D_
            onClick: () => this.Click(item, ind),_x000D_
            key : ind,_x000D_
            ind_x000D_
          }_x000D_
          let clone = React.cloneElement(item, props, [val]);_x000D_
          return clone;_x000D_

    )_x000D_
  }

you can use a string formatter to pad any integer with zeros. It acts just like C's printf.

>>> d = datetime.date.today()
>>> '%02d' % d.month
'03'

Updated for py36: Use f-strings! For general ints you can use the d formatter and explicitly tell it to pad with zeros:

 >>> d = datetime.date.today()
 >>> f"{d.month:02d}"
 '07'

But datetimes are special and come with special formatters that are already zero padded:

 >>> f"{d:%d}"  # the day
 '01'
 >>> f"{d:%m}"  # the month
 '07'

Here I am taking Mobile No From EditText It may start from +91 or 0 but i am getting actual 10 digits. Hope this will help you.

              String mob=edit_mobile.getText().toString();
                    if (mob.length() >= 10) {
                        if (mob.contains("+91")) {
                            mob= mob.substring(3, 13);
                        }
                        if (mob.substring(0, 1).contains("0")) {
                            mob= mob.substring(1, 11);
                        }
                        if (mob.contains("+")) {
                            mob= mob.replace("+", "");
                        }
                        mob= mob.substring(0, 10);
                        Log.i("mob", mob);

                    }

Don't use data-toggle attribute so that you can control the toggle behavior by yourself. So it will avoid 'race-condition'

my codes:

button group template (written in .erb, embedded ruby for ruby on rails):

<div class="btn-group" id="featuresFilter">
     <% _.each(features, function(feature) { %> <button class="btn btn-primary" data="<%= feature %>"><%= feature %></button> <% }); %>
</div>

and javascript:

onChangeFeatures = function(e){
        var el=e.target;
        $(el).button('toggle');

        var features=el.parentElement;
        var activeFeatures=$(features).find(".active");
        console.log(activeFeatures);
}

onChangeFeatures function will be triggered once the button is clicked.

You have to Select Build Tool Version from your project setting.

1. Select Project App Folder
2. Press F4 OR Right Click on Project App Folder and open Module Settings In The Properties tab select Build Tool Version from List

This will work on my side i hope it will help you.

for future developers, i recommend, delete the index in INDEX TAB using compass... this NOT DELETE ANY document in your collection Manage Indexes

You could pass the messages as explicit URL parameter (appropriately encoded), or store the messages into session (cookie) variable before redirecting and then get the variable before rendering the template. For example:

from flask import session, url_for

def do_baz():
    messages = json.dumps({"main":"Condition failed on page baz"})
    session['messages'] = messages
    return redirect(url_for('.do_foo', messages=messages))

@app.route('/foo')
def do_foo():
    messages = request.args['messages']  # counterpart for url_for()
    messages = session['messages']       # counterpart for session
    return render_template("foo.html", messages=json.loads(messages))

(encoding the session variable might not be necessary, flask may be handling it for you, but can't recall the details)

Or you could probably just use Flask Message Flashing if you just need to show simple messages.

FOR WINDOWS:

In my case, I was working on Windows OS and I got the same error while running autoconf.

• I simply open configure.ac file with my NOTEPAD++ IDE.

• Then I converted the File with EOL conversion into Windows (CR LF) as follows:

  EDIT -> EOL CONVERSION -> WINDOWS (CR LF)

In httpd.conf file you need to remove #

#LoadModule rewrite_module modules/mod_rewrite.so

after removing # line will look like this:

LoadModule rewrite_module modules/mod_rewrite.so

And Apache restart

You can control client cache with HTTP headers. This works in any web framework.

You can set the directives these headers to have fine grained control over how and when to enable|disable cache:

• Cache-Control
• Surrogate-Control
• Expires
• ETag (very good one)
• Pragma (if you want to support old browsers)

Good caching is good, but very complex, in all computer systems. Take a look at https://helmetjs.github.io/docs/nocache/#the-headers for more information.

You can in fact access the memory of a temporary object by using a compound literal (C99):

#define IS_LITTLE_ENDIAN (1 == *(unsigned char *)&(const int){1})

Which GCC will evaluate at compile time.

For pre 1.7 i would say an equivalent to Integer.compare(x, y) is:

Integer.valueOf(x).compareTo(y);

Let's take a question : Reverse a String. I shall do this using stream().collect(). But first I shall change the string into an ArrayList .

    public class StringReverse1 {
    public static void main(String[] args) {

        String a = "Gini Gina  Proti";

        List<String> list = new ArrayList<String>(Arrays.asList(a.split("")));

        list.stream()
        .collect(Collectors.toCollection( LinkedList :: new ))
        .descendingIterator()
        .forEachRemaining(System.out::println);



    }}

If you are using Google Chrome browser, you can use chrome console api:

• console.time: call it at the point in your code where you want to start the timer
• console.timeEnd: call it to stop the timer

The elapsed time between these two calls is displayed in the console.

For detail info, please see the doc link: https://developers.google.com/chrome-developer-tools/docs/console

After editing @Wesley Rice's answer a couple times, I decided my changes were just getting too big to continue changing his answer instead of writing my own. So, I decided I need to write my own!

Read each line of a file in and operate on it line-by-line like this:

#!/bin/bash
input="/path/to/txt/file"
while IFS= read -r line
do
  echo "$line"
done < "$input"

This comes directly from author Vivek Gite here: https://www.cyberciti.biz/faq/unix-howto-read-line-by-line-from-file/. He gets the credit!

Syntax: Read file line by line on a Bash Unix & Linux shell:
1. The syntax is as follows for bash, ksh, zsh, and all other shells to read a file line by line
2. while read -r line; do COMMAND; done < input.file
3. The -r option passed to read command prevents backslash escapes from being interpreted.
4. Add IFS= option before read command to prevent leading/trailing whitespace from being trimmed -
5. while IFS= read -r line; do COMMAND_on $line; done < input.file

And now to answer this now-closed question which I also had: Is it possible to `git add` a list of files from a file? - here's my answer:

Note that FILES_STAGED is a variable containing the absolute path to a file which contains a bunch of lines where each line is a relative path to a file I'd like to do git add on. This code snippet is about to become part of the "eRCaGuy_dotfiles/useful_scripts/sync_git_repo_to_build_machine.sh" file in this project, to enable easy syncing of files in development from one PC (ex: a computer I code on) to another (ex: a more powerful computer I build on): https://github.com/ElectricRCAircraftGuy/eRCaGuy_dotfiles.

while IFS= read -r line
do
    echo "  git add \"$line\""
    git add "$line" 
done < "$FILES_STAGED"

i have alreay 2 situations where directives and services/factories didnt play well.

the scenario is that i have (had) a directive that has dependency injection of a service, and from the directive i ask the service to make an ajax call (with $http).

in the end, in both cases the ng-Repeat did not file at all, even when i gave the array an initial value.

i even tried to make a directive with a controller and an isolated-scope

only when i moved everything to a controller and it worked like magic.

What is monkey patching? Monkey patching is a technique used to dynamically update the behavior of a piece of code at run-time.

Why use monkey patching? It allows us to modify or extend the behavior of libraries, modules, classes or methods at runtime without actually modifying the source code

Conclusion Monkey patching is a cool technique and now we have learned how to do that in Python. However, as we discussed, it has its own drawbacks and should be used carefully.

For more info Please refer [1]: https://medium.com/@nagillavenkatesh1234/monkey-patching-in-python-explained-with-examples-25eed0aea505

I believe those comments refer specifically to the browsers, i.e., clicking links and submitting forms, not XMLHttpRequest. XMLHttpRequest is just a custom client that you wrote in JavaScript that uses the browser as a runtime.

UPDATE: To clarify, I did not mean (though I did write) that you wrote XMLHttpRequest; I meant that you wrote the code that uses XMLHttpRequest. The browsers do not natively support XMLHttpRequest. XMLHttpRequest comes from the JavaScript runtime, which may be hosted by a browser, although it isn't required to be (see Rhino). That's why people say browsers don't support PUT and DELETE—because it's actually JavaScript that is supporting them.

First, ask the program to tell you what is wrong by checking the errno, which is set on failure, such as during fseek or ftell.

Others (tonio & LatinSuD) have explained the mistake with handling stdin versus checking for a filename. Namely, first check argc (argument count) to see if there are any command line parameters specified if (argc > 1), treating - as a special case meaning stdin.

If no parameters are specified, then assume input is (going) to come from stdin, which is a stream not file, and the fseek function fails on it.

In the case of a stream, where you cannot use file-on-disk oriented library functions (i.e. fseek and ftell), you simply have to count the number of bytes read (including trailing newline characters) until receiving EOF (end-of-file).

For usage with large files you could speed it up by using fgets to a char array for more efficient reading of the bytes in a (text) file. For a binary file you need to use fopen(const char* filename, "rb") and use fread instead of fgetc/fgets.

You could also check the for feof(stdin) / ferror(stdin) when using the byte-counting method to detect any errors when reading from a stream.

The sample below should be C99 compliant and portable.

#include <stdio.h>
#include <stdlib.h>
#include <errno.h>
#include <string.h>

long getSizeOfInput(FILE *input){
   long retvalue = 0;
   int c;

   if (input != stdin) {
      if (-1 == fseek(input, 0L, SEEK_END)) {
         fprintf(stderr, "Error seek end: %s\n", strerror(errno));
         exit(EXIT_FAILURE);
      }
      if (-1 == (retvalue = ftell(input))) {
         fprintf(stderr, "ftell failed: %s\n", strerror(errno));
         exit(EXIT_FAILURE);
      }
      if (-1 == fseek(input, 0L, SEEK_SET)) {
         fprintf(stderr, "Error seek start: %s\n", strerror(errno));
         exit(EXIT_FAILURE);
      }
   } else {
      /* for stdin, we need to read in the entire stream until EOF */
      while (EOF != (c = fgetc(input))) {
         retvalue++;
      }
   }

   return retvalue;
}

int main(int argc, char **argv) {
   FILE *input;

   if (argc > 1) {
      if(!strcmp(argv[1],"-")) {
         input = stdin;
      } else {
         input = fopen(argv[1],"r");
         if (NULL == input) {
            fprintf(stderr, "Unable to open '%s': %s\n",
                  argv[1], strerror(errno));
            exit(EXIT_FAILURE);
         }
      }
   } else {
      input = stdin;
   }

   printf("Size of file: %ld\n", getSizeOfInput(input));

   return EXIT_SUCCESS;
}

I had the same error with Symfony on wamp and PHP 7.0.0.

symptoms

None of the JS and CSS dependencies was loaded on the "dev" environnement, with error Failed to load resource: net::ERR_CONNECTION_RESET

solution

It's effectively a certificate problem in php.ini. You need to set the property curl.cainfo to a valid certificate in the line :

curl.cainfo = C:\your\wamp\path\bin\cacert\cacert.pem

String.valueOf('X') will create you a String "X"

"X".charAt(0) will give you the character 'X'

You could do $stmt->queryString to obtain the SQL query used in the statement. If you want to save the entire $stmt variable (I can't see why), you could just copy it. It is an instance of PDOStatement so there is apparently no advantage in storing it.

Try this from your AndroidTabRestaurantDescSearchListView activity

Intent intent  = new Intent(this,RatingDescriptionSearchActivity.class );
intent.putExtras( getIntent().getExtras() );
startActivity( intent );  

And then from RatingDescriptionSearchActivity activity just call

getIntent().getStringExtra("key")

VB 6 provides a Clipboard object that makes all of this extremely simple and convenient, but unfortunately that's not available from VBA.

If it were me, I'd go the API route. There's no reason to be scared of calling native APIs; the language provides you with the ability to do that for a reason.

However, a simpler alternative is to use the DataObject class, which is part of the Forms library. I would only recommend going this route if you are already using functionality from the Forms library in your app. Adding a reference to this library only to use the clipboard seems a bit silly.

For example, to place some text on the clipboard, you could use the following code:

Go to "Settings" -> "Password & security" -> "Privacy" -> "Special app access" -> "Device admin apps" and select the account which you want to uninstall.

Or Simply

go to setting -> Then search for Device admin apps -> click and select the account which you want to uninstall.

Every element of your vector is a float[4], so when you resize every element needs to default initialized from a float[4]. I take it you tried to initialize with an int value like 0?

Try:

static float zeros[4] = {0.0, 0.0, 0.0, 0.0};
myvector.resize(newsize, zeros);

Use document.activeElement

Should work.

P.S getElementById("myID") not getElementById("#myID")

GRANT SELECT ON *.* TO 'user'@'localhost' IDENTIFIED BY 'password';

This will create a user with SELECT privilege for all database including Views.

Saw this thread while looking for something else and I know it is super old, but I wanted to add my 2 cents.

NEVER USE VLOOKUP. It's one of the worst performing formulas in excel. Use index match instead. It even works without sorting data, unless you have a -1 or 1 in the end of the match formula (explained more below)

Here is a link with the appropriate formulas.

The Sheet 2 formula would be this: =IF(A2="","",INDEX(Sheet1!B:B,MATCH($A2,Sheet1!$A:$A,0)))

• IF(A2="","", means if A2 is blank, return a blank value
• INDEX(Sheet1!B:B, is saying INDEX B:B where B:B is the data you want to return. IE the name column.
• Match(A2, is saying to Match A2 which is the ID you want to return the Name for.
• Sheet1!A:A, is saying you want to match A2 to the ID column in the previous sheet
• ,0)) is specifying you want an exact value. 0 means return an exact match to A2, -1 means return smallest value greater than or equal to A2, 1 means return the largest value that is less than or equal to A2. Keep in mind -1 and 1 have to be sorted.

More information on the Index/Match formula

Other fun facts: $ means absolute in a formula. So if you specify $B$1 when filling a formula down or over keeps that same value. If you over $B1, the B remains the same across the formula, but if you fill down, the 1 increases with the row count. Likewise, if you used B$1, filling to the right will increment the B, but keep the reference of row 1.

I also included the use of indirect in the second section. What indirect does is allow you to use the text of another cell in a formula. Since I created a named range sheet1!A:A = ID, sheet1!B:B = Name, and sheet1!C:C=Price, I can use the column name to have the exact same formula, but it uses the column heading to change the search criteria.

Good luck! Hope this helps.

The proper Swift operator is is:

if touch.view is UIPickerView {
    // touch.view is of type UIPickerView
}

Of course, if you also need to assign the view to a new constant, then the if let ... as? ... syntax is your boy, as Kevin mentioned. But if you don't need the value and only need to check the type, then you should use the is operator.

Having tried the solution suggested by Zelazny on a relatively large DataFrame (~400k rows) I found it to be very slow. Here is an alternative that I found to run orders of magnitude faster on my data set.

df = pd.DataFrame({
    'sp' : ['MM1', 'MM1', 'MM1', 'MM2', 'MM2', 'MM2', 'MM4', 'MM4', 'MM4'],
    'mt' : ['S1', 'S1', 'S3', 'S3', 'S4', 'S4', 'S2', 'S2', 'S2'],
    'val' : ['a', 'n', 'cb', 'mk', 'bg', 'dgb', 'rd', 'cb', 'uyi'],
    'count' : [3,2,5,8,10,1,2,2,7]
    })

df_grouped = df.groupby(['sp', 'mt']).agg({'count':'max'})

df_grouped = df_grouped.reset_index()

df_grouped = df_grouped.rename(columns={'count':'count_max'})

df = pd.merge(df, df_grouped, how='left', on=['sp', 'mt'])

df = df[df['count'] == df['count_max']]

Depends on how much money you got...

sounds flippant, but actually it's pertinant.

Only today we had an issue where a record failed to be inserted into our Rate table, because one of the columns (GrossRate) is set to Decimal (11,4), and our Product department just got a contract for rooms in some amazing resort in Bora Bora, that sell for several million Pacific Francs per night... something that was never anticpated when the database schema was designed 10 years ago.

To manually generate a Certificate, you need a Certificate Signing Request (CSR) file from your Mac. To create a CSR file, follow the instructions below to create one using Keychain Access.

Create a CSR file. In the Applications folder on your Mac, open the Utilities folder and launch Keychain Access.

Within the Keychain Access drop down menu, select Keychain Access > Certificate Assistant > Request a Certificate from a Certificate Authority.

In the Certificate Information window, enter the following information: In the User Email Address field, enter your email address. In the Common Name field, create a name for your private key (e.g., John Doe Dev Key). The CA Email Address field should be left empty. In the "Request is" group, select the "Saved to disk" option. Click Continue within Keychain Access to complete the CSR generating process.

If you're having an issue where the Resources added are images and are not getting copied to your build folder on compiling. You need to change the "Build Action" to None from Resource ( which is the default) and change the Copy to "If Newer" or "Always" as shown below :

I know its an old post, but just to clear this problem... you're just using your classes at the wrong place :D

First of all you could use

svg { fill: red; }

in your main.css to get it red. This does have effect. You could probably use node selectors as well to get specific paths.

Second thing is, you declared the class to the img-tag.

<img class='socIcon'....

You actually should declare it inside your SVG. if you have different paths you could define more of course.

<?xml version="1.0" encoding="utf-8"?>
<?xml-stylesheet href="stylesheets/main.css" type="text/css"?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd">

<svg version="1.1" id="Layer_1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" viewBox="0 0 56.69 56.69">
<g>
    <path class="myClassForMyPath" d="M28.44......./>
</g>
</svg>

Now you could change the color in your main.css like

.myClassForMyPath {
    fill: yellow;
}

I had to execute the command below:

npm config set registry http://registry.npmjs.org/

However, that will make npm install packages over an insecure HTTP connection. If you can, you should stick with

npm config set registry https://registry.npmjs.org/

instead to install over HTTPS.

When to use each

@staticmethod function is nothing more than a function defined inside a class. It is callable without instantiating the class first. It’s definition is immutable via inheritance.

• Python does not have to instantiate a bound-method for object.
• It eases the readability of the code: seeing @staticmethod, we know that the method does not depend on the state of object itself;

@classmethod function also callable without instantiating the class, but its definition follows Sub class, not Parent class, via inheritance, can be overridden by subclass. That’s because the first argument for @classmethod function must always be cls (class).

• Factory methods, that are used to create an instance for a class using for example some sort of pre-processing.
• Static methods calling static methods: if you split a static methods in several static methods, you shouldn't hard-code the class name but use class methods

here is good link to this topic.

I agree with the accepted answer. But for me, the issue was not that, instead I had to modify my Servlet-Class name from:-

<servlet-class>org.glassfish.jersey.servlet.ServletContainer.class</servlet-class> 

To:

<servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>

So, removing .class worked fine in my case. Hope it will help somebody!

The URI to open a specific channel in Slack app is:

slack://channel?id=<CHANNEL-ID>&team=<TEAM-ID>

You will probably need these resources of the Slack API to get IDs of your team and channel:

• GET https://slack.com/api/team.info
• GET https://slack.com/api/channels.list?exclude_archived=1

Here's the full documentation from Slack

$("h3").text("context")

Just use method "text()".

The .text() method cannot be used on form inputs or scripts. To set or get the text value of input or textarea elements, use the .val() method. To get the value of a script element, use the .html() method.

http://api.jquery.com/text/

./gradlew

Your directory with gradlew is not included in the PATH, so you must specify path to the gradlew. . means "current directory".

Do not use the ToList() method as in the accepted answer !

Running SQL profiler, I verified and found that ToList() function gets all the records from the database. It is really bad performance !!

I would have run this query by pure sql command as follows:

string query = "Update YourTable Set ... Where ...";    
context.Database.ExecuteSqlCommandAsync(query, new SqlParameter("@ColumnY", value1), new SqlParameter("@ColumnZ", value2));

This would operate the update in one-shot without selecting even one row.

You should do:

git commit . -m "save arezzo files"

If you set unique parameters, then the cache does not work, for example:

$.ajax({
    url : "my_url",
    data : {
        'uniq_param' : (new Date()).getTime(),
        //other data
    }});

Add in activity

requestWindowFeature(Window.FEATURE_NO_TITLE);

and add your style.xml file with the following two lines:

<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>

__call__ makes any object be callable as a function.

This example will output 8:

class Adder(object):
  def __init__(self, val):
    self.val = val

  def __call__(self, val):
    return self.val + val

func = Adder(5)
print func(3)

Don't forget to take into consideration the global flag in your regexp :

var reg = /abc/g;
!!'abcdefghi'.match(reg); // => true
!!'abcdefghi'.match(reg); // => true
reg.test('abcdefghi');    // => true
reg.test('abcdefghi');    // => false <=

This is because Regexp keeps track of the lastIndex when a new match is found.

SQLite has a printf function which does exactly that:

SELECT printf('%s-%.2d-%.4d', col1, col2, col3) FROM mytable

As theczechsensation comment above I try to search about Gradle Build Varians and I found this link: http://code.tutsplus.com/tutorials/using-gradle-build-variants--cms-25005 This is a very simple solution. This is what I did: - In build.gradle:

flavorDimensions "version"

productFlavors {
    trial{
        applicationId "org.de_studio.recentappswitcher.trial"
        flavorDimension "version"
    }
    pro{
        applicationId "org.de_studio.recentappswitcher.pro"
        flavorDimension "version"
    }

}

Then I have 2 more version of my app: pro and trial with 2 diffrent packageName which is 2 applicationId in above code so I can upload both to Google Play. I still just code in the "main" section and use the getpackageName to switch between to version. Just go to the link I gave for detail.

You cannot iterate backwards with the jQuery each function, but you can still leverage jQuery syntax.

Try the following:

//get an array of the matching DOM elements   
var liItems = $("ul#myUL li").get();

//iterate through this array in reverse order    
for(var i = liItems.length - 1; i >= 0; --i)
{
  //do Something
}

As of October 2016, Google has added a file upload question type in native Google Forms, no Google Apps Script needed. See documentation.

Yup, I have found the solution for dis issue.

• Create one slider box with extra width from both side( Which we can use to add item space from both sides ).
• Create Inner Item Content with proper width & margin from both sides( This should be your actual wrapper size )
• Done

If the folder is accessible from the browser (not outside the document root of your web server), then you just need to output links to the locations of those files. If they are outside the document root, you will need to have links, buttons, whatever, that point to a PHP script that handles getting the files from their location and streaming to the response.

Very simple:

1. Open command prompt as an administrator.
2. Type python.exe (provided you have given path of it in environmental variables)

Then, In the same command prompt window the python interpreter will start with >>>

This worked for me.

There are a few ways depending on some data rules that you have not included, but here is one way using what you gave.

SELECT
    t1.Field1,
    t2.Field2
FROM Table1 t1
    LEFT JOIN Table1 t2 ON t1.FK = t2.FK AND t2.Field1 IS NULL

Another way:

SELECT
    t1.Field1,
    (SELECT Field2 FROM Table2 t2 WHERE t2.FK = t1.FK AND Field1 IS NULL) AS Field2
FROM Table1 t1

On Excel 2010 try this:

1. select the cell you want to check if is used somewhere in a formula;
2. Formulas -> Trace Dependents (on Formula Auditing menu)

Following the documentation of fopen:

``a'' Open for writing. The file is created if it does not exist. The stream is positioned at the end of the file. Subsequent writes to the file will always end up at the then cur- rent end of file, irrespective of any intervening fseek(3) or similar.

So if you pFile2=fopen("myfile2.txt", "a"); the stream is positioned at the end to append automatically. just do:

FILE *pFile;
FILE *pFile2;
char buffer[256];

pFile=fopen("myfile.txt", "r");
pFile2=fopen("myfile2.txt", "a");
if(pFile==NULL) {
    perror("Error opening file.");
}
else {
    while(fgets(buffer, sizeof(buffer), pFile)) {
        fprintf(pFile2, "%s", buffer);
    }
}
fclose(pFile);
fclose(pFile2);

The exponential function is e^x where e is a mathematical constant called Euler's number, approximately 2.718281. This value has a close mathematical relationship with pi and the slope of the curve e^x is equal to its value at every point. np.exp() calculates e^x for each value of x in your input array.

.length is a one-off property of Java. It's used to find the size of a single dimensional array.

.length() is a method. It's used to find the length of a String. It avoids duplicating the value.

I was looking for an answer on what |= does in Groovy and although answers above are right on they did not help me understand a particular piece of code I was looking at.

In particular, when applied to a boolean variable "|=" will set it to TRUE the first time it encounters a truthy expression on the right side and will HOLD its TRUE value for all |= subsequent calls. Like a latch.

Here a simplified example of this:

groovy> boolean result  
groovy> //------------ 
groovy> println result           //<-- False by default
groovy> println result |= false 
groovy> println result |= true   //<-- set to True and latched on to it
groovy> println result |= false 

Output:

false
false
true
true

Edit: Why is this useful?

Consider a situation where you want to know if anything has changed on a variety of objects and if so notify some one of the changes. So, you would setup a hasChanges boolean and set it to |= diff (a,b) and then |= dif(b,c) etc. Here is a brief example:

groovy> boolean hasChanges, a, b, c, d 
groovy> diff = {x,y -> x!=y}  
groovy> hasChanges |= diff(a,b) 
groovy> hasChanges |= diff(b,c) 
groovy> hasChanges |= diff(true,false) 
groovy> hasChanges |= diff(c,d) 
groovy> hasChanges 

Result: true

HTML href link click:

<a ="{{ route('download',$name->file) }}"> Download  </a>

In controller:

public function download($file){
    $file_path = public_path('uploads/cv/'.$file);
    return response()->download( $file_path);
}

In route:

Route::get('/download/{file}','Controller@download')->name('download');

The easiest solution working fine for me is this:

export CFLAGS=-ggdb
export CXXFLAGS=-ggdb

CMake will append them to all configurations' flags. Just make sure to clear CMake cache.

It sounds like that if you request faq.html the webserver signals your browser that the file is in UTF-8 encoding.

Check that with your browser which encoding is announced and used, please see the documentation of your browser how to do that. Every browser has this, most often accessible via the menu (to specify your preference which website's encoding should be used) and to see what the server returned, you often find this in page properties.

Then it sounds like that if you request faq.php the webserver singals your browser that the file is in some other encoding. Probably no charset/encoding is given as per default PHP configuration setting. As it's a PHP file you can most often solve this by changing the PHP configuration default_charset^Docs directive:

default_charset = "UTF-8"

Locate your php.ini on the host and edit it accordingly.

If you don't have the php.ini available, you can change this by code as well by using the ini_set^Docs function:

ini_set('default_charset', 'UTF-8');

Take care that you change this very early in your script because PHP needs to be able to send out headers to have this working, and headers can't be set any longer if they have already been send.

Manually sending the Content-Type header-line does work, too:

header('Content-Type: text/html; charset=UTF-8');

Additionally it's good practice that all the HTML pages you output have this header as well in their HTML <head> section:

<html>
  <head>
    ...
    <meta http-equiv="Content-Type" content="text/html;charset=UTF-8">
    ...

Hope this is helpful.

In the Windows Powershell console, type

[System.IO.Directory]::GetFiles("\\.\\pipe\\")

get-childitem \\.\pipe\

This returns a list of objects. If you want the name only:

(get-childitem \\.\pipe\).FullName

(The second example \\.\pipe\ does not work in Powershell 7, but the first example does)

Spring Data JpaRepository

The Spring Data JpaRepository defines the following two methods:

• getOne, which returns an entity proxy that is suitable for setting a @ManyToOne or @OneToOne parent association when persisting a child entity.
• findById, which returns the entity POJO after running the SELECT statement that loads the entity from the associated table

However, in your case, you didn't call either getOne or findById:

Person person = personRepository.findOne(1L);

So, I assume the findOne method is a method you defined in the PersonRepository. However, the findOne method is not very useful in your case. Since you need to fetch the Person along with is roles collection, it's better to use a findOneWithRoles method instead.

Custom Spring Data methods

You can define a PersonRepositoryCustom interface, as follows:

public interface PersonRepository
    extends JpaRepository<Person, Long>, PersonRepositoryCustom { 

}

public interface PersonRepositoryCustom {
    Person findOneWithRoles(Long id);
}

And define its implementation like this:

public class PersonRepositoryImpl implements PersonRepositoryCustom {

    @PersistenceContext
    private EntityManager entityManager;

    @Override
    public Person findOneWithRoles(Long id)() {
        return entityManager.createQuery("""
            select p 
            from Person p
            left join fetch p.roles
            where p.id = :id 
            """, Person.class)
        .setParameter("id", id)
        .getSingleResult();
    }
}

That's it!

netstat -ano|grep 443|grep LISTEN

will tell you whether a process is listening on port 443 (you might have to replace LISTEN with a string in your language, though, depending on your system settings).

I struggled with this for a long time. I am using Angular 6 and I found that

let headers = new HttpHeaders();
headers = headers.append('key', 'value');

did not work. But what did work was

let headers = new HttpHeaders().append('key', 'value');

did, which makes sense when you realize they are immutable. So having created a header you can't add to it. I haven't tried it, but I suspect

let headers = new HttpHeaders();
let headers1 = headers.append('key', 'value');

would work too.

This error occurs when we parse json content to model object. Json content type is string. For example: https://dotnetfiddle.net/uFClKj Some times, an api that we call may return an error. If we do not check the response status, but proceed to parse the response to model, this issue will occur.

After combining the suggestions from the other answers, I realized I came up with about the same thing as Ronnie Overby's answer. Here are some tests to point out some things to think about:

1. folders can have "extensions": C:\Temp\folder_with.dot
2. files cannot end with a directory separator (slash)
3. There are technically two directory separators which are platform specific -- i.e. may or may not be slashes (Path.DirectorySeparatorChar and Path.AltDirectorySeparatorChar)

Tests (Linqpad)

var paths = new[] {
    // exists
    @"C:\Temp\dir_test\folder_is_a_dir",
    @"C:\Temp\dir_test\is_a_dir_trailing_slash\",
    @"C:\Temp\dir_test\existing_folder_with.ext",
    @"C:\Temp\dir_test\file_thats_not_a_dir",
    @"C:\Temp\dir_test\notadir.txt",
    // doesn't exist
    @"C:\Temp\dir_test\dne_folder_is_a_dir",
    @"C:\Temp\dir_test\dne_folder_trailing_slash\",
    @"C:\Temp\dir_test\non_existing_folder_with.ext",
    @"C:\Temp\dir_test\dne_file_thats_not_a_dir",
    @"C:\Temp\dir_test\dne_notadir.txt",        
};

foreach(var path in paths) {
    IsFolder(path/*, false*/).Dump(path);
}

Results

C:\Temp\dir_test\folder_is_a_dir
  True 
C:\Temp\dir_test\is_a_dir_trailing_slash\
  True 
C:\Temp\dir_test\existing_folder_with.ext

The main problem here is that it ignores all and any error: Out of memory, CPU is burning, user wants to stop, program wants to exit, Jabberwocky is killing users.

This is way too much. In your head, you're thinking "I want to ignore this network error". If something unexpected goes wrong, then your code silently continues and breaks in completely unpredictable ways that no one can debug.

That's why you should limit yourself to ignoring specifically only some errors and let the rest pass.

Try This :

--Default Instance

SQLCMD -S SERVERNAME -E

--OR
--Named Instance

SQLCMD -S SERVERNAME\INSTANCENAME -E

--OR

SQLCMD -S SERVERNAME\INSTANCENAME,1919 -E

More details can be found here

I know there area lot of correct answers here, with respect to all of them I introduce this hack :

In StartUp.cs

services.AddSingleton<IHttpContextAccessor, HttpContextAccessor>();

and then everywhere you need HttpContext you can use :

httpContext = new HttpContextAccessor().HttpContext;

Hope it helps ;)

The following is an instantiation of the various "just print it" suggestions. I found it instructive.

#include "stdio.h"

int main() {
    static int x = 5;
    static int *p = &x;
    printf("(int) p   => %d\n",(int) p);
    printf("(int) p++ => %d\n",(int) p++);
    x = 5; p = &x;
    printf("(int) ++p => %d\n",(int) ++p);
    x = 5; p = &x;
    printf("++*p      => %d\n",++*p);
    x = 5; p = &x;
    printf("++(*p)    => %d\n",++(*p));
    x = 5; p = &x;
    printf("++*(p)    => %d\n",++*(p));
    x = 5; p = &x;
    printf("*p++      => %d\n",*p++);
    x = 5; p = &x;
    printf("(*p)++    => %d\n",(*p)++);
    x = 5; p = &x;
    printf("*(p)++    => %d\n",*(p)++);
    x = 5; p = &x;
    printf("*++p      => %d\n",*++p);
    x = 5; p = &x;
    printf("*(++p)    => %d\n",*(++p));
    return 0;
}

It returns

(int) p   => 256688152
(int) p++ => 256688152
(int) ++p => 256688156
++*p      => 6
++(*p)    => 6
++*(p)    => 6
*p++      => 5
(*p)++    => 5
*(p)++    => 5
*++p      => 0
*(++p)    => 0

I cast the pointer addresses to ints so they could be easily compared.

I compiled it with GCC.

The specific problem is that you're declaring a new variable instead of assigning to an existing one:

char * ret = new char[strlen(array) + 1 + 1];
^^^^^^ Remove this

and trying to compare string values by comparing pointers:

if (array!="")     // Wrong - compares pointer with address of string literal
if (array[0] == 0) // Better - checks for empty string

although there's no need to make that comparison at all; the first branch will do the right thing whether or not the string is empty.

The more general problem is that you're messing around with nasty, error-prone C-style string manipulation in C++. Use std::string and it will manage all the memory allocation for you:

std::string appendCharToString(std::string const & s, char a) {
    return s + a;
}

There's a shortcut to delete the branch in the origin:

git push origin :<branch_name>

Which is the same as doing git push origin --delete <branch_name>

1. Right-click on your table and pick option Backup..
2. On File Options, set Filepath/Filename and pick PLAIN for Format
3. Ignore Dump Options #1 tab
4. In Dump Options #2 tab, check USE INSERT COMMANDS
5. In Dump Options #2 tab, check Use Column Inserts if you want column names in your inserts.
6. Hit Backup button

You can configure logging in your settings.py file.

One example:

if DEBUG:
    # will output to your console
    logging.basicConfig(
        level = logging.DEBUG,
        format = '%(asctime)s %(levelname)s %(message)s',
    )
else:
    # will output to logging file
    logging.basicConfig(
        level = logging.DEBUG,
        format = '%(asctime)s %(levelname)s %(message)s',
        filename = '/my_log_file.log',
        filemode = 'a'
    )

However that's dependent upon setting DEBUG, and maybe you don't want to have to worry about how it's set up. See this answer on How can I tell whether my Django application is running on development server or not? for a better way of writing that conditional. Edit: the example above is from a Django 1.1 project, logging configuration in Django has changed somewhat since that version.

Why are people using list slicing (slow because it copies to a new list), importing a library function, or trying to rotate an array for this?

Use a normal for-loop with range(start, stop, step) (where start and step are optional arguments).

For example, looping through an array starting at index 1:

for i in range(1, len(arr)):
    print(arr[i])

To clone an existing database with postgres you can do that

/* KILL ALL EXISTING CONNECTION FROM ORIGINAL DB (sourcedb)*/
SELECT pg_terminate_backend(pg_stat_activity.pid) FROM pg_stat_activity 
WHERE pg_stat_activity.datname = 'SOURCE_DB' AND pid <> pg_backend_pid();

/* CLONE DATABASE TO NEW ONE(TARGET_DB) */
CREATE DATABASE TARGET_DB WITH TEMPLATE SOURCE_DB OWNER USER_DB;

IT will kill all the connection to the source db avoiding the error

ERROR:  source database "SOURCE_DB" is being accessed by other users

Use gsub:

data1$c <- gsub('_', '-', data1$c)

I only use MicrosoftAdvertising.Mobile and Microsoft.Advertising.Mobile.UI and I am served ads. The SDK should only add the DLLs not reference itself.

Note: You need to explicitly set width and height Make sure the phone dialer, and web browser capabilities are enabled

Followup note: Make sure that after you've removed the SDK DLL, that the xmlns references are not still pointing to it. The best route to take here is

1. Remove the XAML for the ad
2. Remove the xmlns declaration (usually at the top of the page, but sometimes will be declared in the ad itself)
3. Remove the bad DLL (the one ending in .SDK )
4. Do a Clean and then Build (clean out anything remaining from the DLL)
5. Add the xmlns reference (actual reference is below)
6. Add the ad to the page (example below)

Here is the xmlns reference:

xmlns:AdNamepace="clr-namespace:Microsoft.Advertising.Mobile.UI;assembly=Microsoft.Advertising.Mobile.UI" 

Then the ad itself:

<AdNamespace:AdControl x:Name="myAd" Height="80" Width="480"                    AdUnitId="yourAdUnitIdHere" ApplicationId="yourIdHere"/> 

Another option is to use GKMersenneTwisterRandomSource from GameKit. The docs say:

A deterministic pseudo-random source that generates random numbers based on a mersenne twister algorithm. This is a deterministic random source suitable for creating reliable gameplay mechanics. It is slightly slower than an Arc4 source, but more random, in that it has a longer period until repeating sequences. While deterministic, this is not a cryptographic random source. It is however suitable for obfuscation of gameplay data.

import GameKit

let minValue = 0
let maxValue = 100

var randomDistribution: GKRandomDistribution?
let randomSource = GKMersenneTwisterRandomSource()
randomDistribution = GKRandomDistribution(randomSource: randomSource, lowestValue: minValue, highestValue: maxValue)
let number = randomDistribution?.nextInt() ?? 0
print(number)

Example taken from Apple's sample code: https://github.com/carekit-apple/CareKit/blob/master/CareKitPrototypingTool/OCKPrototyper/CareKitPatient/RandomNumberGeneratorHelper.swift

I agree the documentation on imageEdgeInsets and titleEdgeInsets should be better, but I figured out how to get the correct positioning without resorting to trial and error.

The general idea is here at this question, but that was if you wanted both text and image centered. We don't want the image and text to be centered individually, we want the image and the text to be centered together as a single entity. This is in fact what UIButton already does so we simply need to adjust the spacing.

CGFloat spacing = 10; // the amount of spacing to appear between image and title
tabBtn.imageEdgeInsets = UIEdgeInsetsMake(0, 0, 0, spacing);
tabBtn.titleEdgeInsets = UIEdgeInsetsMake(0, spacing, 0, 0);

I also turned this into a category for UIButton so it will be easy to use:

UIButton+Position.h

@interface UIButton(ImageTitleCentering)

-(void) centerButtonAndImageWithSpacing:(CGFloat)spacing;

@end

UIButton+Position.m

@implementation UIButton(ImageTitleCentering)

-(void) centerButtonAndImageWithSpacing:(CGFloat)spacing {
    self.imageEdgeInsets = UIEdgeInsetsMake(0, 0, 0, spacing);
    self.titleEdgeInsets = UIEdgeInsetsMake(0, spacing, 0, 0);
}

@end

So now all I have to do is:

[button centerButtonAndImageWithSpacing:10];

And I get what I need every time. No more messing with the edge insets manually.

EDIT: Swapping Image and Text

In response to @Javal in comments

Using this same mechanism, we can swap the image and the text. To accomplish the swap, simply use a negative spacing but also include the width of the text and the image. This will require frames to be known and layout performed already.

[self.view layoutIfNeeded];
CGFloat flippedSpacing = -(desiredSpacing + button.currentImage.size.width + button.titleLabel.frame.size.width);
[button centerButtonAndImageWithSpacing:flippedSpacing];

Of course you will probably want to make a nice method for this, potentially adding a second category method, this is left as an exercise to the reader.

RFC 2616 (Hypertext Transfer Protocol — HTTP/1.1) states there is no limit to the length of a query string (section 3.2.1). RFC 3986 (Uniform Resource Identifier — URI) also states there is no limit, but indicates the hostname is limited to 255 characters because of DNS limitations (section 2.3.3).

While the specifications do not specify any maximum length, practical limits are imposed by web browser and server software. Based on research which is unfortunately no longer available on its original site (it leads to a shady seeming loan site) but which can still be found at Internet Archive Of Boutell.com:

• Microsoft Internet Explorer (Browser)
  Microsoft states that the maximum length of a URL in Internet Explorer is 2,083 characters, with no more than 2,048 characters in the path portion of the URL. Attempts to use URLs longer than this produced a clear error message in Internet Explorer.

• Microsoft Edge (Browser)
  The limit appears to be around 81578 characters. See URL Length limitation of Microsoft Edge

• Chrome
  It stops displaying the URL after 64k characters, but can serve more than 100k characters. No further testing was done beyond that.

• Firefox (Browser)
  After 65,536 characters, the location bar no longer displays the URL in Windows Firefox 1.5.x. However, longer URLs will work. No further testing was done after 100,000 characters.

• Safari (Browser)
  At least 80,000 characters will work. Testing was not tried beyond that.

• Opera (Browser)
  At least 190,000 characters will work. Stopped testing after 190,000 characters. Opera 9 for Windows continued to display a fully editable, copyable and pasteable URL in the location bar even at 190,000 characters.

• Apache (Server)
  Early attempts to measure the maximum URL length in web browsers bumped into a server URL length limit of approximately 4,000 characters, after which Apache produces a "413 Entity Too Large" error. The current up to date Apache build found in Red Hat Enterprise Linux 4 was used. The official Apache documentation only mentions an 8,192-byte limit on an individual field in a request.

• Microsoft Internet Information Server (Server)
  The default limit is 16,384 characters (yes, Microsoft's web server accepts longer URLs than Microsoft's web browser). This is configurable.

• Perl HTTP::Daemon (Server)
  Up to 8,000 bytes will work. Those constructing web application servers with Perl's HTTP::Daemon module will encounter a 16,384 byte limit on the combined size of all HTTP request headers. This does not include POST-method form data, file uploads, etc., but it does include the URL. In practice this resulted in a 413 error when a URL was significantly longer than 8,000 characters. This limitation can be easily removed. Look for all occurrences of 16x1024 in Daemon.pm and replace them with a larger value. Of course, this does increase your exposure to denial of service attacks.

@Before(JUnit4) -> @BeforeEach(JUnit5) - method is called before every test

@After(JUnit4) -> @AfterEach(JUnit5) - method is called after every test

@BeforeClass(JUnit4) -> @BeforeAll(JUnit5) - static method is called before executing all tests in this class. It can be a large task as starting server, read file, making db connection...

@AfterClass(JUnit4) -> @AfterAll(JUnit5) - static method is called after executing all tests in this class.

You can use Joda time library for Java. It would be much easier to calculate time-diff between dates with it.

Sample snippet for time-diff:

Days d = Days.daysBetween(startDate, endDate);
int days = d.getDays();

GNU parallel

I was making a synthetic compilation benchmark and couldn't be bothered to write a Makefile, so I used:

sudo apt-get install parallel
ls | grep -E '\.c$' | parallel -t --will-cite "gcc -c -o '{.}.o' '{}'"

Explanation:

• {.} takes the input argument and removes its extension
• -t prints out the commands being run to give us an idea of progress
• --will-cite removes the request to cite the software if you publish results using it...

parallel is so convenient that I could even do a timestamp check myself:

ls | grep -E '\.c$' | parallel -t --will-cite "\
  if ! [ -f '{.}.o' ] || [ '{}' -nt '{.}.o' ]; then
    gcc -c -o '{.}.o' '{}'
  fi
"

xargs -P can also run jobs in parallel, but it is a bit less convenient to do the extension manipulation or run multiple commands with it: Calling multiple commands through xargs

Parallel linking was asked at: Can gcc use multiple cores when linking?

TODO: I think I read somewhere that compilation can be reduced to matrix multiplication, so maybe it is also possible to speed up single file compilation for large files. But I can't find a reference now.

Tested in Ubuntu 18.10.

Assuming, as seems to be the case, ${triningIdArray} is a server-side placeholder that is replaced with JS array-literal syntax, just lose the quotes. So:

var traingIds = ${triningIdArray};

not

var traingIds = "${triningIdArray}";

To see all tables in another schema, you need to have one or more of the following system privileges:

SELECT ANY DICTIONARY
(SELECT | INSERT | UPDATE | DELETE) ANY TABLE

or the big-hammer, the DBA role.

With any of those, you can select:

SELECT DISTINCT OWNER, OBJECT_NAME 
  FROM DBA_OBJECTS
 WHERE OBJECT_TYPE = 'TABLE'
   AND OWNER = '[some other schema]'

Without those system privileges, you can only see tables you have been granted some level of access to, whether directly or through a role.

SELECT DISTINCT OWNER, OBJECT_NAME 
  FROM ALL_OBJECTS
 WHERE OBJECT_TYPE = 'TABLE'
   AND OWNER = '[some other schema]'

Lastly, you can always query the data dictionary for your own tables, as your rights to your tables cannot be revoked (as of 10g):

SELECT DISTINCT OBJECT_NAME 
  FROM USER_OBJECTS
 WHERE OBJECT_TYPE = 'TABLE'

After change our php.ini, make sure to restart Apache web server.

Simply:

 try {
    const cmd = 'git rev-parse --is-inside-work-tree';
    execSync(cmd).toString();
 } catch (error) {
    console.log(`Status Code: ${error.status} with '${error.message}'`;
 }

Ref: https://stackoverflow.com/a/43077917/104085

    execSync(cmd).toString();
 } catch (error) {
    error.status;  // 0 : successful exit, but here in exception it has to be greater than 0
    error.message; // Holds the message you typically want.
    error.stderr;  // Holds the stderr output. Use `.toString()`.
    error.stdout;  // Holds the stdout output. Use `.toString()`.

For those of you who want more customization in their splitting function, I wrote a recursive algorithm that splits a given string with a list of characters to split on. I wrote this before I saw the above post. I hope it helps some frustrated programmers.

splitString = function(string, splitters) {
    var list = [string];
    for(var i=0, len=splitters.length; i<len; i++) {
        traverseList(list, splitters[i], 0);
    }
    return flatten(list);
}

traverseList = function(list, splitter, index) {
    if(list[index]) {
        if((list.constructor !== String) && (list[index].constructor === String))
            (list[index] != list[index].split(splitter)) ? list[index] = list[index].split(splitter) : null;
        (list[index].constructor === Array) ? traverseList(list[index], splitter, 0) : null;
        (list.constructor === Array) ? traverseList(list, splitter, index+1) : null;    
    }
}

flatten = function(arr) {
    return arr.reduce(function(acc, val) {
        return acc.concat(val.constructor === Array ? flatten(val) : val);
    },[]);
}

var stringToSplit = "people and_other/things";
var splitList = [" ", "_", "/"];
splitString(stringToSplit, splitList);

Example above returns: ["people", "and", "other", "things"]

Note: flatten function was taken from Rosetta Code

First select current session sql_mode:

SELECT @@SESSION.sql_mode;

Then you will get something like that default value:

'ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION'

and then set sql_mode without 'NO_ZERO_DATE':

SET SESSION sql_mode = 'ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION';

If you have grants, you can do it also for GLOBAL:

SELECT @@GLOBAL.sql_mode;
SET GLOBAL sql_mode = '...';

If you're deleting something, you should always use POST and not GET, so using confirm() is a bad idea. What I do in your situation is use a modal popup like jqModal and display a form with yes/no buttons inside the popup.

for some weird reason bootstrap tabs were not working for me until i was using href like:-

<li class="nav-item"><a class="nav-link" href="#a" data-toggle="tab">First</a></li>

but it started working as soon as i replaced href with data-target like:-

<li class="nav-item"><a class="nav-link" data-target="#a" data-toggle="tab">First</a></li>

<nav class="navbar navbar-toggleable-md navbar-light bg-danger">

So you have this code here, you must be knowing that bg-danger gives some sort of color. Now if you want to give some custom color to your page then simply change bg-danger to bg-color. Then either create a separate css-file or you can workout with style element in same tag . Just do this-

`<nav class="navbar navbar-toggleable-md navbar-light bg-color" style="background-color: cyan;">` . 

That would do.

Step 1. Store the reference to the XMLHttpRequest object

var xmlHttp = createXmlHttpRequestObject();

Step 2. Retrieve the XMLHttpRequest object

function createXmlHttpRequestObject() {
    // will store the reference to the XMLHttpRequest object
    var xmlHttp;
    // if running Internet Explorer
    if (window.ActiveXObject) {
        try {
            xmlHttp = new ActiveXObject("Microsoft.XMLHTTP");
        } catch (e) {
            xmlHttp = false;
        }
    }
    // if running Mozilla or other browsers
    else {
        try {
            xmlHttp = new XMLHttpRequest();
        } catch (e) {
            xmlHttp = false;
        }
    }
    // return the created object or display an error message
    if (!xmlHttp)
        alert("Error creating the XMLHttpRequest object.");
    else
        return xmlHttp;
}

Step 3. Make asynchronous HTTP request using the XMLHttpRequest object

function process() {
    // proceed only if the xmlHttp object isn't busy
    if (xmlHttp.readyState == 4 || xmlHttp.readyState == 0) {
        // retrieve the name typed by the user on the form
        item = encodeURIComponent(document.getElementById("input_item").value);
        // execute the your_file.php page from the server
        xmlHttp.open("GET", "your_file.php?item=" + item, true);
        // define the method to handle server responses
        xmlHttp.onreadystatechange = handleServerResponse;
        // make the server request
        xmlHttp.send(null);
    }
}

Step 4. Executed automatically when a message is received from the server

function handleServerResponse() {

    // move forward only if the transaction has completed
    if (xmlHttp.readyState == 4) {
        // status of 200 indicates the transaction completed successfully
        if (xmlHttp.status == 200) {
            // extract the XML retrieved from the server
            xmlResponse = xmlHttp.responseText;
            document.getElementById("put_response").innerHTML = xmlResponse;
            // restart sequence
        }
        // a HTTP status different than 200 signals an error
        else {
            alert("There was a problem accessing the server: " + xmlHttp.statusText);
        }
    }
}

There are some great answers already, but none of them address a complete list of what the __future__ statement currently supports.

Put simply, the __future__ statement forces Python interpreters to use newer features of the language.

The features that it currently supports are the following:

nested_scopes

Prior to Python 2.1, the following code would raise a NameError:

def f():
    ...
    def g(value):
        ...
        return g(value-1) + 1
    ...

The from __future__ import nested_scopes directive will allow for this feature to be enabled.

generators

Introduced generator functions such as the one below to save state between successive function calls:

def fib():
    a, b = 0, 1
    while 1:
       yield b
       a, b = b, a+b

division

Classic division is used in Python 2.x versions. Meaning that some division statements return a reasonable approximation of division ("true division") and others return the floor ("floor division"). Starting in Python 3.0, true division is specified by x/y, whereas floor division is specified by x//y.

The from __future__ import division directive forces the use of Python 3.0 style division.

absolute_import

Allows for parenthesis to enclose multiple import statements. For example:

from Tkinter import (Tk, Frame, Button, Entry, Canvas, Text,
    LEFT, DISABLED, NORMAL, RIDGE, END)

Instead of:

from Tkinter import Tk, Frame, Button, Entry, Canvas, Text, \
    LEFT, DISABLED, NORMAL, RIDGE, END

Or:

from Tkinter import Tk, Frame, Button, Entry, Canvas, Text
from Tkinter import LEFT, DISABLED, NORMAL, RIDGE, END

with_statement

Adds the statement with as a keyword in Python to eliminate the need for try/finally statements. Common uses of this are when doing file I/O such as:

with open('workfile', 'r') as f:
     read_data = f.read()

print_function:

Forces the use of Python 3 parenthesis-style print() function call instead of the print MESSAGE style statement.

unicode_literals

Introduces the literal syntax for the bytes object. Meaning that statements such as bytes('Hello world', 'ascii') can be simply expressed as b'Hello world'.

generator_stop

Replaces the use of the StopIteration exception used inside generator functions with the RuntimeError exception.

One other use not mentioned above is that the __future__ statement also requires the use of Python 2.1+ interpreters since using an older version will throw a runtime exception.

No, you cannot change package name unless you're okay with publishing it as a new app in Play Store:

Once you publish your application under its manifest package name, this is the unique identity of the application forever more. Switching to a different name results in an entirely new application, one that can’t be installed as an update to the existing application. Android manual confirms it as well here:

Caution: Once you publish your application, you cannot change the package name. The package name defines your application's identity, so if you change it, then it is considered to be a different application and users of the previous version cannot update to the new version. If you're okay with publishing new version of your app as a completely new entity, you can do it of course - just remove old app from Play Store (if you want) and publish new one, with different package name.

The given code works correctly. I have tried in the Application Life Cycle sample.

I haven't got B and C in the back stack after starting activity A with flag, FLAG_ACTIVITY_CLEAR_TOP

This is an expansion to totem's answer. It does basically the same thing but the property matching is based on the serialized json object, not reflect the .net object. This is important if you're using [JsonProperty], using the CamelCasePropertyNamesContractResolver, or doing anything else that will cause the json to not match the .net object.

Usage is simple:

[KnownType(typeof(B))]
public class A
{
   public string Name { get; set; }
}

public class B : A
{
   public string LastName { get; set; }
}

Converter code:

/// <summary>
/// Use KnownType Attribute to match a divierd class based on the class given to the serilaizer
/// Selected class will be the first class to match all properties in the json object.
/// </summary>
public class KnownTypeConverter : JsonConverter {
    public override bool CanConvert( Type objectType ) {
        return System.Attribute.GetCustomAttributes( objectType ).Any( v => v is KnownTypeAttribute );
    }

    public override bool CanWrite {
        get { return false; }
    }

    public override object ReadJson( JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer ) {
        // Load JObject from stream
        JObject jObject = JObject.Load( reader );

        // Create target object based on JObject
        System.Attribute[ ] attrs = System.Attribute.GetCustomAttributes( objectType );  // Reflection. 

        // check known types for a match. 
        foreach( var attr in attrs.OfType<KnownTypeAttribute>( ) ) {
            object target = Activator.CreateInstance( attr.Type );

            JObject jTest;

                return target;

        var list = new List<KeyValuePair<string, JToken>>( );
        foreach( var t in obj ) {
            list.Add( t );

Install firebug and use console.log instead of alert. Then you will see the exact element your accessing.

Google's Guava library provides a nice helper method to do this: Doubles.tryParse(String). You use it like Double.parseDouble but it returns null rather than throwing an exception if the string does not parse to a double.

Here my solution without going backward and without a temporary list

while (listBox1.Items.Count > 0)
{
  string s = listBox1.Items[0] as string;
  // do something with s
  listBox1.Items.RemoveAt(0);
}

I was trying to connect an old phone that I use to test apps on older API versions. Today adb was not finding it.

After trying pretty much everything here, I figured out that the phone was not even showing the system notification about the USB connection going on.

So I looked around for that issue, and found the solution here (credits to the original source):

1. Remove phone from PC and remove battery to shut off phone.
2. Plug USB cable into PC.
3. Plug USB cable (other end) into phone.
4. The PC install new hardware appropriate drivers for a few minutes (phone without battery)
5. Unplug USB cable from phone
6. Put battery back in and turn on phone
7. As the phone boots, hold down Volume up and down. Phone boots into safe mode.
8. Plug USB cable into phone.
9. I saw notification about USB MTP-connecting on the phone. PC have found my phone!
10. After the reboot in normal mode problem was fixed

Not sure step 4. is of any use here on macOS, however I did all the steps and it worked well.

A regex-less version which is easy on the eye:

const trim = (str, chars) => str.split(chars).filter(Boolean).join(chars);

For use cases where we're certain that there's no repetition of the chars off the edges.

I experienced this error once. My problem was that I wasn't adding the FILE_NAME_WHERE_IS_MY_FUNCTION.js

so my file.html never found where my function was

Once I add the "file.js" I resolved the problem

<html ng-app='myApp'>
    <body ng-controller='TextController'>
    ....
    ....
    ....
    <script src="../file.js"></script>
    </body>
</html>

Don't forget to import Foundation or UIKit.

import Foundation
let trimmedString = "   aaa  "".trimmingCharacters(in: .whitespaces)
print(trimmedString)

Result:

"aaa"

Otherwise you'll get:

error: value of type 'String' has no member 'trimmingCharacters'
    return self.trimmingCharacters(in: .whitespaces)

//Disable future dates after current date

$("#datepicker").datepicker('setEndDate', new Date());

//Disable past dates after current date

$("#datepicker").datepicker('setEndDate', new Date());

Hi you can create a customized build on bootstrap, just change the font name in the following pages

Bootstrap 2.3.2 http://getbootstrap.com/2.3.2/customize.html#variables

Bootstrap 3 http://getbootstrap.com/customize/#less-variables

After that, make sure to use proper @font-face in a css file and link that to your page. Or you could use font kit generators.

Rebuild All worked for me. VS2013, IIS Express.

If you wish (like me) to have results containing mulitple rows of various SELECT queries "labelled" and can't manage this within the constraints of the PRINT statement in concert with the Messages tab you could turn it around and simply add messages to the Results tab per the below:

SELECT 'Results from scenario 1'
SELECT
    *
FROM tblSample

Adding a requestedExecutionLevel element to your manifest is only half the battle; you have to remember that UAC can be turned off. If it is, you have to perform the check the old school way and put up an error dialog if the user is not administrator
(call IsInRole(WindowsBuiltInRole.Administrator) on your thread's CurrentPrincipal).

In the above example Error.apply (also Error.call) doesn't do anything for me (Firefox 3.6/Chrome 5). A workaround I use is:

function MyError(message, fileName, lineNumber) {
    var err = new Error();

    if (err.stack) {
        // remove one stack level:
        if (typeof(Components) != 'undefined') {
            // Mozilla:
            this.stack = err.stack.substring(err.stack.indexOf('\n')+1);
        }
        else if (typeof(chrome) != 'undefined' || typeof(process) != 'undefined') {
            // Google Chrome/Node.js:
            this.stack = err.stack.replace(/\n[^\n]*/,'');
        }
        else {
            this.stack = err.stack;
        }
    }
    this.message    = message    === undefined ? err.message    : message;
    this.fileName   = fileName   === undefined ? err.fileName   : fileName;
    this.lineNumber = lineNumber === undefined ? err.lineNumber : lineNumber;
}

MyError.prototype = new Error();
MyError.prototype.constructor = MyError;
MyError.prototype.name = 'MyError';

In Java 8, you can use lambda expression:

map.keySet().removeIf(key -> key condition);

sleep(1.0/24.0)

As to your follow up question if that's the best way: No, you could get not-so-smooth framerates because the rendering of each frame might not take the same amount of time.

You could try one of these solutions:

• Use a timer which fires 24 times a second with the drawing code.
• Create as many frames as possible, create the motion based on the time passed, not per frame.

Another method would be to get the error code from the exception class directly. For example:

catch (Exception ex)
{
    if (ex.InnerException is ServiceResponseException)
       {
        ServiceResponseException srex = ex.InnerException as ServiceResponseException;
        string ErrorCode = srex.ErrorCode.ToString();
       }
}

from np.random import permutation
from sklearn.datasets import load_iris
iris = load_iris()
X = iris.data #numpy array
y = iris.target #numpy array

# Data is currently unshuffled; we should shuffle 
# each X[i] with its corresponding y[i]
perm = permutation(len(X))
X = X[perm]
y = y[perm]

I have been running some time comparisons between the abovementioned versions:

function[0] = 42;
function.insert(std::map<int, int>::value_type(0, 42));
function.insert(std::pair<int, int>(0, 42));
function.insert(std::make_pair(0, 42));

Turns out that time differences between the insert versions are tiny.

#include <map>
#include <vector>
#include <boost/date_time/posix_time/posix_time.hpp>
using namespace boost::posix_time;
class Widget {
public:
    Widget() {
        m_vec.resize(100);
        for(unsigned long it = 0; it < 100;it++) {
            m_vec[it] = 1.0;
        }
    }
    Widget(double el)   {
        m_vec.resize(100);
        for(unsigned long it = 0; it < 100;it++) {
            m_vec[it] = el;
        }
    }
private:
    std::vector<double> m_vec;
};


int main(int argc, char* argv[]) {



    std::map<int,Widget> map_W;
    ptime t1 = boost::posix_time::microsec_clock::local_time();    
    for(int it = 0; it < 10000;it++) {
        map_W.insert(std::pair<int,Widget>(it,Widget(2.0)));
    }
    ptime t2 = boost::posix_time::microsec_clock::local_time();
    time_duration diff = t2 - t1;
    std::cout << diff.total_milliseconds() << std::endl;

    std::map<int,Widget> map_W_2;
    ptime t1_2 = boost::posix_time::microsec_clock::local_time();    
    for(int it = 0; it < 10000;it++) {
        map_W_2.insert(std::make_pair(it,Widget(2.0)));
    }
    ptime t2_2 = boost::posix_time::microsec_clock::local_time();
    time_duration diff_2 = t2_2 - t1_2;
    std::cout << diff_2.total_milliseconds() << std::endl;

    std::map<int,Widget> map_W_3;
    ptime t1_3 = boost::posix_time::microsec_clock::local_time();    
    for(int it = 0; it < 10000;it++) {
        map_W_3[it] = Widget(2.0);
    }
    ptime t2_3 = boost::posix_time::microsec_clock::local_time();
    time_duration diff_3 = t2_3 - t1_3;
    std::cout << diff_3.total_milliseconds() << std::endl;

    std::map<int,Widget> map_W_0;
    ptime t1_0 = boost::posix_time::microsec_clock::local_time();    
    for(int it = 0; it < 10000;it++) {
        map_W_0.insert(std::map<int,Widget>::value_type(it,Widget(2.0)));
    }
    ptime t2_0 = boost::posix_time::microsec_clock::local_time();
    time_duration diff_0 = t2_0 - t1_0;
    std::cout << diff_0.total_milliseconds() << std::endl;

    system("pause");
}

This gives respectively for the versions (I ran the file 3 times, hence the 3 consecutive time differences for each):

map_W.insert(std::pair<int,Widget>(it,Widget(2.0)));

2198 ms, 2078 ms, 2072 ms

map_W_2.insert(std::make_pair(it,Widget(2.0)));

2290 ms, 2037 ms, 2046 ms

 map_W_3[it] = Widget(2.0);

2592 ms, 2278 ms, 2296 ms

 map_W_0.insert(std::map<int,Widget>::value_type(it,Widget(2.0)));

2234 ms, 2031 ms, 2027 ms

Hence, results between different insert versions can be neglected (didn't perform a hypothesis test though)!

The map_W_3[it] = Widget(2.0); version takes about 10-15 % more time for this example due to an initialization with the default constructor for Widget.

For Evergreen browsers, this will build a staircase based on an incoming character and the number of stairs to build.
function StairCase(character, input) {
    let i = 0;
    while (i < input) {
        const spaces = " ".repeat(input - (i+1));
        const hashes = character.repeat(i + 1);
        console.log(spaces + hashes);
        i++;
    }
}

//Implement
//Refresh the console
console.clear();
StairCase("#",6);   

You can also add a polyfill for Repeat for older browsers

    if (!String.prototype.repeat) {
      String.prototype.repeat = function(count) {
        'use strict';
        if (this == null) {
          throw new TypeError('can\'t convert ' + this + ' to object');
        }
        var str = '' + this;
        count = +count;
        if (count != count) {
          count = 0;
        }
        if (count < 0) {
          throw new RangeError('repeat count must be non-negative');
        }
        if (count == Infinity) {
          throw new RangeError('repeat count must be less than infinity');
        }
        count = Math.floor(count);
        if (str.length == 0 || count == 0) {
          return '';
        }
        // Ensuring count is a 31-bit integer allows us to heavily optimize the
        // main part. But anyway, most current (August 2014) browsers can't handle
        // strings 1 << 28 chars or longer, so:
        if (str.length * count >= 1 << 28) {
          throw new RangeError('repeat count must not overflow maximum string size');
        }
        var rpt = '';
        for (;;) {
          if ((count & 1) == 1) {
            rpt += str;
          }
          count >>>= 1;
          if (count == 0) {
            break;
          }
          str += str;
        }
        // Could we try:
        // return Array(count + 1).join(this);
        return rpt;
      }
    } 

I had the same error but from different reason. In my case I had (tmpfs) partition with only 1GB space and I was downloading big file which finally filled all memory on that partition and I got the same error as you.

an EXE file is created as long as you build the project. you can usually find this on the debug folder of you project.

JavaScript only simple solution

datePickerId.max = new Date().toISOString().split("T")[0];

<input type="date" id="datePickerId" />

One way is to use the lattice package and xyplot():

R> DF <- data.frame(x=1:10, y=rnorm(10)+5, 
+>                  z=sample(letters[1:3], 10, replace=TRUE))
R> DF
    x       y z
1   1 3.91191 c
2   2 4.57506 a
3   3 3.16771 b
4   4 5.37539 c
5   5 4.99113 c
6   6 5.41421 a
7   7 6.68071 b
8   8 5.58991 c
9   9 5.03851 a
10 10 4.59293 b
R> with(DF, xyplot(y ~ x, group=z))

By giving explicit grouping information via variable z, you obtain different colors. You can specify colors etc, see the lattice documentation.

Because z here is a factor variable for which we obtain the levels (== numeric indices), you can also do

R> with(DF, plot(x, y, col=z))

but that is less transparent (to me, at least :) then xyplot() et al.

If you just want the bitmap, This too works

InputStream inputStream = mContext.getContentResolver().openInputStream(uri);
Bitmap bmp = BitmapFactory.decodeStream(inputStream);
if( inputStream != null ) inputStream.close();

sample uri : content://media/external/images/media/12345

You appear to be trying to mix query expression syntax and "normal" lambda expression syntax. You can either use:

IEnumerable<SelectListItem> stores =
        from store in database.Stores
        where store.CompanyID == curCompany.ID
        select new SelectListItem { Value = store.Name, Text = store.ID};
ViewBag.storeSelector = stores;

Or:

IEnumerable<SelectListItem> stores = database.Stores
        .Where(store => store.CompanyID == curCompany.ID)
        .Select(s => new SelectListItem { Value = s.Name, Text = s.ID});
ViewBag.storeSelector = stores;

You can't mix the two like you're trying to.

I was having trouble using Moment Timezone. I am adding this answer just so if somebody else faces the same issue. So I have a date string 2018-06-14 13:51:00 coming from my API. I know that this is stored in UTC but the string doesn't speak for itself.

I let moment timezone know, what timezone this date is from by doing:

let uTCDatetime = momentTz.tz("2018-06-14 13:51:00", "UTC").format();
// If your datetime is from any other timezone then add that instead of "UTC"
// this actually makes the date as : 2018-06-14T13:51:00Z

Now I would like to convert it to a specific timezone by doing:

let dateInMyTimeZone = momentTz.tz(uTCDatetime, "Asia/Kolkata").format("YYYY-MM-DD HH:mm:ss");
// now this results into: 2018-06-14 19:21:00, which is the corresponding date in my timezone.

SQLite also supports a pragma statement called "table_info" which returns one row per column in a table with the name of the column (and other information about the column). You could use this in a query to check for the missing column, and if not present alter the table.

PRAGMA table_info(foo_table_name)

http://www.sqlite.org/pragma.html#pragma_table_info

You can display all image from a folder using simple php script. Suppose folder name “images” and put some image in this folder and then use any text editor and paste this code and run this script. This is php code

    <?php
     $files = glob("images/*.*");
     for ($i=0; $i<count($files); $i++)
      {
        $image = $files[$i];
        $supported_file = array(
                'gif',
                'jpg',
                'jpeg',
                'png'
         );

         $ext = strtolower(pathinfo($image, PATHINFO_EXTENSION));
         if (in_array($ext, $supported_file)) {
            echo basename($image)."<br />"; // show only image name if you want to show full path then use this code // echo $image."<br />";
             echo '<img src="'.$image .'" alt="Random image" />'."<br /><br />";
            } else {
                continue;
            }
          }
       ?>

if you do not check image type then use this code

<?php
$files = glob("images/*.*");
for ($i = 0; $i < count($files); $i++) {
    $image = $files[$i];
    echo basename($image) . "<br />"; // show only image name if you want to show full path then use this code // echo $image."<br />";
    echo '<img src="' . $image . '" alt="Random image" />' . "<br /><br />";

}
?>

Try downloading the certificates/profiles directly from the member centre rather than doing it from Xcode.

It worked for me when I manually downloaded them from the member centre.

You can access columns by index, by name and some other ways:

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

You should probably make sure your DataTable has some columns first...

The syntax to store the command output into a variable is var=$(command).

So you can directly do:

result=$(ls -l | grep -c "rahul.*patle")

And the variable $result will contain the number of matches.

You don't want git revert. That undoes a previous commit. You want git checkout to get git's version of the file from master.

git checkout -- filename.txt

In general, when you want to perform a git operation on a single file, use -- filename.

• git-checkout Documentation
• git-revert Documentation

2020 Update

Git introduced a new command git restore in version 2.23.0. Therefore, if you have git version 2.23.0+, you can simply git restore filename.txt - which does the same thing as git checkout -- filename.txt. The docs for this command do note that it is currently experimental.

• git-restore Documentation

Just telling you about one other possibility: I like using friend definitions for that:

namespace Math
{
    class Matrix
    {
    public:

        [...]

        friend std::ostream& operator<< (std::ostream& stream, const Matrix& matrix) {
            [...]
        }
    };
}

The function will be automatically targeted into the surrounding namespace Math (even though its definition appears within the scope of that class) but will not be visible unless you call operator<< with a Matrix object which will make argument dependent lookup find that operator definition. That can sometimes help with ambiguous calls, since it's invisible for argument types other than Matrix. When writing its definition, you can also refer directly to names defined in Matrix and to Matrix itself, without qualifying the name with some possibly long prefix and providing template parameters like Math::Matrix<TypeA, N>.

you can use jquery validator for that but you need to add jquery.validate.js and jquery.form.js file for that. after including validator file define your validation something like this.

<script type="text/javascript">
$(document).ready(function(){
    $("#formID").validate({
    rules :{
        "data[User][name]" : {
            required : true
        }
    },
    messages :{
        "data[User][name]" : {
            required : 'Enter username'
        }
    }
    });
});
</script>

You can see required : true same there is many more property like for email you can define email : true for number number : true

I agree with both previous answers. Basically, you want to use what is known as a "lightbox" - http://en.wikipedia.org/wiki/Lightbox_(JavaScript)

It is essentially a div than is created within the DOM of your current window/tab. In addition to the div that contains your dialog, a transparent overlay blocks the user from engaging all underlying elements. This can effectively create a modal dialog (i.e. user MUST make some kind of decision before moving on).

your button xml:

 <Button
    android:id="@+id/btn"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="jump to activity b"
    />

Mainactivity.java:

 Button btn=findViewVyId(R.id.btn);
btn.setOnClickListener(btnclick);
btnclick.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
               Intent intent=new Intent();
                intent.setClass(Mainactivity.this,b.class);
                startActivity(intent);
    }
});

OnCreate:

//Add comment fragment
            container = FindViewById<FrameLayout>(Resource.Id.frmAttachPicture);
            mPictureFragment = new fmtAttachPicture();

            var trans = SupportFragmentManager.BeginTransaction();
            trans.Add(container.Id, mPictureFragment, "fmtPicture");
            trans.Show(mPictureFragment); trans.Commit();

This is how I hide the fragment in click event 1

//Close fragment
    var trans = SupportFragmentManager.BeginTransaction();
    trans.Hide(mPictureFragment);
    trans.AddToBackStack(null);
    trans.Commit();

Then Shows it back int event 2

var trans = SupportFragmentManager.BeginTransaction();
            trans.Show(mPictureFragment); trans.Commit();

How about using a drop-in solution like ShareThis or AddThis? They have similar functionality, so it's quite possible they already solved the problem.

AddThis's code has a huge if/else browser version fork for saving favorites, though, with most branches ending in prompting the user to manually add the favorite themselves, so I am thinking that no such pure JavaScript implementation exists.

Otherwise, if you only need to support IE and Firefox, you have IE's window.externalAddFavorite( ) and Mozilla's window.sidebar.addPanel( ).

If you need to frequently use LIKE, you can simplify the problem a bit. A custom method like () can be created in the model that inherits the Eloquent ORM:

public  function scopeLike($query, $field, $value){
        return $query->where($field, 'LIKE', "%$value%");
}

So then you can use this method in such way:

User::like('name', 'Tomas')->get();

I agree with everyone else here: With JS on the client, the cat is out of the bag and there is nothing completely foolproof that can be done.

Having said that; in some cases I do this to put some hurdles in the way of those who want to take a look at the code. This is how the algorithm works (roughly)

1. The server creates 3 hashed and salted values. One for the current timestamp, and the other two for each of the next 2 seconds. These values are sent over to the client via Ajax to the client as a comma delimited string; from my PHP module. In some cases, I think you can hard-bake these values into a script section of HTML when the page is formed, and delete that script tag once the use of the hashes is over The server is CORS protected and does all the usual SERVER_NAME etc check (which is not much of a protection but at least provides some modicum of resistance to script kiddies).

2. Also it would be nice, if the the server checks if there was indeed an authenticated user's client doing this

3. The client then sends the same 3 hashed values back to the server thru an ajax call to fetch the actual JS that I need. The server checks the hashes against the current time stamp there... The three values ensure that the data is being sent within the 3 second window to account for latency between the browser and the server

4. The server needs to be convinced that one of the hashes is matched correctly; and if so it would send over the crucial JS back to the client. This is a simple, crude "One time use Password" without the need for any database at the back end.

5. This means, that any hacker has only the 3 second window period since the generation of the first set of hashes to get to the actual JS code.

6. The entire client code can be inside an IIFE function so some of the variables inside the client are even more harder to read from the Inspector console

   This is not any deep solution: A determined hacker can register, get an account and then ask the server to generate the first three hashes; by doing tricks to go around Ajax and CORS; and then make the client perform the second call to get to the actual code -- but it is a reasonable amount of work.

Moreover, if the Salt used by the server is based on the login credentials; the server may be able to detect who is that user who tried to retreive the sensitive JS (The server needs to do some more additional work regarding the behaviour of the user AFTER the sensitive JS was retreived, and block the person if the person, say for example, did not do some other activity which was expected)

An old, crude version of this was done for a hackathon here: http://planwithin.com/demo/tadr.html That wil not work in case the server detects too much latency, and it goes beyond the 3 second window period

The instantclient works only by defining the folder in the windows PATH environment variable. But you can "install" manually to create some keys in the Windows registry. How?

1) Download instantclient (http://www.oracle.com/technetwork/topics/winsoft-085727.html)

2) Unzip the ZIP file (eg c:\oracle\instantclient).

3) Include the above path in the PATH.

4) Create the registry key:

• Windows 32bit: [HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE]
• Windows 64bit: [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\ORACLE]

5) In the above registry key, create a sub-key starts with "KEY_" followed by the name of the installation you want:

• Windows 32bit: [HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE\KEY_INSTANTCLIENT]
• Windows 64bit: [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\ORACLE\KEY_INSTANTCLIENT]

6) Now create at least three string values ??in the above key:

• NLS_LANG = BRAZILIAN PORTUGUESE_BRAZIL.WE8MSWIN1252 (complete list here: http://docs.oracle.com/cd/B19306_01/install.102/b14317/gblsupp.htm)
• ORACLE_HOME = c:\oracle\instantclient (the same folder in PATH)
• ORACLE_HOME_NAME = MY_INSTANTCLIENT (choose any name)

For those who use Quest SQL Navigator or Quest Toad for Oracle will see that it works. Displays the message "Home is valid.":

The registry keys are now displayed for selecting the oracle client:

Fast, and works for large strings:

    private String hexToBin(String hex){
        hex = hex.replaceAll("0", "0000");
        hex = hex.replaceAll("1", "0001");
        hex = hex.replaceAll("2", "0010");
        hex = hex.replaceAll("3", "0011");
        hex = hex.replaceAll("4", "0100");
        hex = hex.replaceAll("5", "0101");
        hex = hex.replaceAll("6", "0110");
        hex = hex.replaceAll("7", "0111");
        hex = hex.replaceAll("8", "1000");
        hex = hex.replaceAll("9", "1001");
        hex = hex.replaceAll("A", "1010");
        hex = hex.replaceAll("B", "1011");
        hex = hex.replaceAll("C", "1100");
        hex = hex.replaceAll("D", "1101");
        hex = hex.replaceAll("E", "1110");
        hex = hex.replaceAll("F", "1111");
        return hex;
    }

According to Opera the CSS3 standard does not define the use of border-radius on TDs. My experience is that Firefox and Chrome support it but Opera does not (don't know about IE). The workaround is to wrap the td content in a div and then apply the border-radius to the div.
