If you just do gcc program.c -o program -mno-cygwin it will compile just fine and you won't need to add cygwin1.dll to your path and you can just go ahead and distribute your executable to a computer which doesn't have cygwin installed and it will still run. Hope this helps

It happened with me, I used jquery.min.js file that downloaded from bootstrap site it is not working, I tried same page with other jquery.min.js file it worked fine so if you face this problem try to reference other jquery.min.js file in your page and try again

Swift 5

There are three (3) ways to create a empty array in Swift and shorthand syntax way is always preferred.

Method 1: Shorthand Syntax

var arr = [Int]()

Method 2: Array Initializer

var arr = Array<Int>()

Method 3: Array with an Array Literal

var arr:[Int] = []

Method 4: Credit goes to @BallpointBen

var arr:Array<Int> = []

I will keep my accepted answer as the "simple and obvious way to do it" - however, that does not cover overlapping occurrences. Finding out those can be done naively, with multiple checking of the slices - as in: sum("GCAAAAAGH"[i:].startswith("AAA") for i in range(len("GCAAAAAGH")))

(which yields 3) - it can be done by trick use of regular expressions, as can be seen at Python regex find all overlapping matches? - and it can also make for fine code golfing - This is my "hand made" count for overlappingocurrences of patterns in a string which tries not to be extremely naive (at least it does not create new string objects at each interaction):

def find_matches_overlapping(text, pattern):
    lpat = len(pattern) - 1
    matches = []
    text = array("u", text)
    pattern = array("u", pattern)
    indexes = {}
    for i in range(len(text) - lpat):
        if text[i] == pattern[0]:
            indexes[i] = -1
        for index, counter in list(indexes.items()):
            counter += 1
            if text[i] == pattern[counter]:
                if counter == lpat:
                    matches.append(index)
                    del indexes[index]
                else:
                    indexes[index] = counter
            else:
                del indexes[index]
    return matches

def count_matches(text, pattern):
    return len(find_matches_overlapping(text, pattern))

Designed to do essentially the inverse of what you wanted, here's one of my toolkit toys:

 lstype<-function(type='closure'){
inlist<-ls(.GlobalEnv)
if (type=='function') type <-'closure'
typelist<-sapply(sapply(inlist,get),typeof)
return(names(typelist[typelist==type]))
}

This could happen very often if you change your namespace. Return the name of your namespace,just like it used to be, and that should make it work!

I found the gtag() function worked, instead of the ga() function.

In the index.html file, within the <head> section:

<script async src="https://www.googletagmanager.com/gtag/js?id=TrackingId"></script>
<script>
  window.dataLayer = window.dataLayer || [];
  function gtag(){dataLayer.push(arguments);}
  gtag('js', new Date());
  gtag('config', 'TrackingId');
</script>

In the AngularJS code:

app.run(function ($rootScope, $location) {
  $rootScope.$on('$routeChangeSuccess', function() {
    gtag('config', 'TrackingId', {'page_path': $location.path()});
  });
});

Replace TrackingId with your own Tracking Id.

While value types have default values and can not be null, they also need to be explicitly initialized in order to be used. You can think of these two rules as side by side rules.

Value types can not be null ? the compiler guarantees that. If you ask how, the error message you got is the answer. Once you call their constructors, they got initialized with their default values.

int tmpCnt; // Not accepted
int tmpCnt = new Int(); // Default value applied tmpCnt = 0

The whole code if somebody need it.

void alarm(Context context, Calendar calendar) {
    AlarmManager alarmManager = (AlarmManager)context.getSystemService(ALARM_SERVICE);

    final String SOME_ACTION = "com.android.mytabs.MytabsActivity.AlarmReceiver";
    IntentFilter intentFilter = new IntentFilter(SOME_ACTION);

    AlarmReceiver mReceiver = new AlarmReceiver();
    context.registerReceiver(mReceiver, intentFilter);

    Intent anotherIntent = new Intent(SOME_ACTION);
    PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, anotherIntent, 0);
    alramManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pendingIntent);

    Toast.makeText(context, "Added", Toast.LENGTH_LONG).show();
}

class AlarmReceiver extends BroadcastReceiver {     
    @Override
    public void onReceive(Context context, Intent arg1) {
        Toast.makeText(context, "Started", Toast.LENGTH_LONG).show();
    }
}

Numeric primitives in class scope are initialized to zero when not explicitly initialized.

Numeric primitives in local scope (variables in methods) must be explicitly initialized.

If you are only worried about division by zero exceptions, checking that your double is not exactly zero works great.

if(value != 0)
    //divide by value is safe when value is not exactly zero.

Otherwise when checking if a floating point value like double or float is 0, an error threshold is used to detect if the value is near 0, but not quite 0.

public boolean isZero(double value, double threshold){
    return value >= -threshold && value <= threshold;
}

After some years with node, I can say that there are no conventions for the directory/file structure. However most (professional) express applications use a setup like:

/
  /bin - scripts, helpers, binaries
  /lib - your application
  /config - your configuration
  /public - your public files
  /test - your tests

An example which uses this setup is nodejs-starter.

I personally changed this setup to:

/
  /etc - contains configuration
  /app - front-end javascript files
    /config - loads config
    /models - loads models
  /bin - helper scripts
  /lib - back-end express files
    /config - loads config to app.settings
    /models - loads mongoose models
    /routes - sets up app.get('..')...
  /srv - contains public files
  /usr - contains templates
  /test - contains test files

In my opinion, the latter matches better with the Unix-style directory structure (whereas the former mixes this up a bit).

I also like this pattern to separate files:

lib/index.js

var http = require('http');
var express = require('express');

var app = express();

app.server = http.createServer(app);

require('./config')(app);

require('./models')(app);

require('./routes')(app);

app.server.listen(app.settings.port);

module.exports = app;

lib/static/index.js

var express = require('express');

module.exports = function(app) {

  app.use(express.static(app.settings.static.path));

};

This allows decoupling neatly all source code without having to bother dependencies. A really good solution for fighting nasty Javascript. A real-world example is nearby which uses this setup.

Update (filenames):

Regarding filenames most common are short, lowercase filenames. If your file can only be described with two words most JavaScript projects use an underscore as the delimiter.

Update (variables):

Regarding variables, the same "rules" apply as for filenames. Prototypes or classes, however, should use camelCase.

Update (styleguides):

• https://github.com/feross/standard
• https://github.com/airbnb/javascript

If you only have experience with imperative/OO languages, I suggest using a more conventional functional language as a stepping stone. Haskell is really different and you have to understand a lot of different concepts to get anywhere. I suggest tackling a ML-style language (like e.g. F#) first.

The traditional way to deal with asynchronous calls in JavaScript has been with callbacks. Say we had to make three calls to the server, one after the other, to set up our application. With callbacks, the code might look something like the following (assuming a xhrGET function to make the server call):

// Fetch some server configuration
    xhrGET('/api/server-config', function(config) {
        // Fetch the user information, if he's logged in
        xhrGET('/api/' + config.USER_END_POINT, function(user) {
            // Fetch the items for the user
            xhrGET('/api/' + user.id + '/items', function(items) {
                // Actually display the items here
            });
        });
    });

In this example, we first fetch the server configuration. Then based on that, we fetch information about the current user, and then finally get the list of items for the current user. Each xhrGET call takes a callback function that is executed when the server responds.

Now of course the more levels of nesting we have, the harder the code is to read, debug, maintain, upgrade, and basically work with. This is generally known as callback hell. Also, if we needed to handle errors, we need to possibly pass in another function to each xhrGET call to tell it what it needs to do in case of an error. If we wanted to have just one common error handler, that is not possible.

The Promise API was designed to solve this nesting problem and the problem of error handling.

The Promise API proposes the following:

1. Each asynchronous task will return a promise object.
2. Each promise object will have a then function that can take two arguments, a success handler and an error handler.
3. The success or the error handler in the then function will be called only once, after the asynchronous task finishes.
4. The then function will also return a promise, to allow chaining multiple calls.
5. Each handler (success or error) can return a value, which will be passed to the next function as an argument, in the chain of promises.
6. If a handler returns a promise (makes another asynchronous request), then the next handler (success or error) will be called only after that request is finished.

So the previous example code might translate to something like the following, using promises and the $http service(in AngularJs):

$http.get('/api/server-config').then(
    function(configResponse) {
        return $http.get('/api/' + configResponse.data.USER_END_POINT);
    }
).then(
    function(userResponse) {
        return $http.get('/api/' + userResponse.data.id + '/items');
    }
).then(
    function(itemResponse) {
        // Display items here
    }, 
    function(error) {
        // Common error handling
    }
);

Propagating Success and Error

Chaining promises is a very powerful technique that allows us to accomplish a lot of functionality, like having a service make a server call, do some postprocessing of the data, and then return the processed data to the controller. But when we work with promise chains, there are a few things we need to keep in mind.

Consider the following hypothetical promise chain with three promises, P1, P2, and P3. Each promise has a success handler and an error handler, so S1 and E1 for P1, S2 and E2 for P2, and S3 and E3 for P3:

xhrCall()
  .then(S1, E1) //P1
  .then(S2, E2) //P2
  .then(S3, E3) //P3

In the normal flow of things, where there are no errors, the application would flow through S1, S2, and finally, S3. But in real life, things are never that smooth. P1 might encounter an error, or P2 might encounter an error, triggering E1 or E2.

Consider the following cases:

• We receive a successful response from the server in P1, but the data returned is not correct, or there is no data available on the server (think empty array). In such a case, for the next promise P2, it should trigger the error handler E2.

• We receive an error for promise P2, triggering E2. But inside the handler, we have data from the cache, ensuring that the application can load as normal. In that case, we might want to ensure that after E2, S3 is called.

So each time we write a success or an error handler, we need to make a call—given our current function, is this promise a success or a failure for the next handler in the promise chain?

If we want to trigger the success handler for the next promise in the chain, we can just return a value from the success or the error handler

If, on the other hand, we want to trigger the error handler for the next promise in the chain, we can do that using a deferred object and calling its reject() method

Now What is deferred object?

Deferred objects in jQuery represents a unit of work that will be completed later, typically asynchronously. Once the unit of work completes, the deferred object can be set to resolved or failed.

A deferred object contains a promise object. Via the promise object you can specify what is to happen when the unit of work completes. You do so by setting callback functions on the promise object.

Deferred objects in Jquery : https://api.jquery.com/jquery.deferred/

Deferred objects in AngularJs : https://docs.angularjs.org/api/ng/service/$q

For what is worth:

the closest integer to any given input as shown in the following table can be calculated using Math.ceil or Math.floor depending of the distance between the input and the next integer

+-------+--------+
| input | output |
+-------+--------+
|     1 |      0 |
|     2 |      0 |
|     3 |      5 |
|     4 |      5 |
|     5 |      5 |
|     6 |      5 |
|     7 |      5 |
|     8 |     10 |
|     9 |     10 |
+-------+--------+

private int roundClosest(final int i, final int k) {
    int deic = (i % k);
    if (deic <= (k / 2.0)) {
        return (int) (Math.floor(i / (double) k) * k);
    } else {
        return (int) (Math.ceil(i / (double) k) * k);
    }
}

Your exception says it all "Connection reset". The connection between your java process and the db server was lost, which could have happened for almost any reason(like network issues). The SQLRecoverableException just means that its recoverable, but the root cause is connection reset.

Both are equivalent. Take a look at the following:

int[] array;

// is equivalent to

int array[];

int var, array[];

// is equivalent to

int var;
int[] array;

int[] array1, array2[];

// is equivalent to

int[] array1;
int[][] array2;

public static int[] getArray()
{
    // ..
}

// is equivalent to

public static int getArray()[]
{
    // ..
}

If you are using intellij, then try restarting intellij cache

1. File-> Invalidate cache/restart
2. clean and build project

See if it works, it worked for me.

While I don't know myself, I would certainly hope that #2 is incorrect...I'd like to think that Windows isn't going to AUTOMATICALLY give out my login information (least of all my password!) to any machine, let alone one that isn't part of my trust.

Regardless, have you explored the impersonation architecture? Your code is going to look similar to this:

using (System.Security.Principal.WindowsImpersonationContext context = System.Security.Principal.WindowsIdentity.Impersonate(token))
{
    // Do network operations here

    context.Undo();
}

In this case, the token variable is an IntPtr. In order to get a value for this variable, you'll have to call the unmanaged LogonUser Windows API function. A quick trip to pinvoke.net gives us the following signature:

[System.Runtime.InteropServices.DllImport("advapi32.dll", SetLastError = true)]
public static extern bool LogonUser(
    string lpszUsername,
    string lpszDomain,
    string lpszPassword,
    int dwLogonType,
    int dwLogonProvider,
    out IntPtr phToken
);

Username, domain, and password should seem fairly obvious. Have a look at the various values that can be passed to dwLogonType and dwLogonProvider to determine the one that best suits your needs.

This code hasn't been tested, as I don't have a second domain here where I can verify, but this should hopefully put you on the right track.

I think it needs to be checked if any row is selected or not? The below code would check it:

var entityGrid = $("#EntitesGrid").data("kendoGrid");
            var selectedItem = entityGrid.dataItem(entityGrid.select());
            if (selectedItem != undefined)
                alert("The Row Is SELECTED");
            else
                alert("NO Row Is SELECTED")

It depends on the task you want to do, but I wouldn't use it. Also, check if the thread-save-ness you want to accompish couldn't be done by synchronize(this) in the first place? There are also some nice locks in the API that might help you :)

if(jQuery('#frmTest input[type=checkbox]:checked').length) { … }

$.ajax({
  type: "POST",
  contentType: "application/json; charset=utf-8",
  url: "ChnagePassword.aspx/AutocompleteSuggestions",
  data: "{'searchstring':'" + request.term + "','st':'Arb'}",
  dataType: "json",
  success: function (data) {
     response($.map(data.d, function (item) {
         return { value: item }
     }))
  },
  error: function (result) {
      alert("Error");
  }
});

If you want to ignore seconds for example you can use

func isDate(Date, equalTo: Date, toUnitGranularity: NSCalendar.Unit) -> Bool

Example compare if it's the same day:

Calendar.current.isDate(date1, equalTo: date2, toGranularity: .day)

Instead of using .get, using like this should be ok for lists. Just a usage difference.

>>> l = [1]
>>> l[10] if 10 < len(l) else 'fail'
'fail'

In case anyone else is looking for this... as of April 2013, you can still get the free Visual Studio edition of Crystal Reports from this web site: SAP Crystal Reports - Downloads (updated url).

It installs into Visual Studio 2010 or VS 2012, and you can edit and save RPT files with as much capability as the standard Crystal Reports editor.

It's not possible, sorry. If really needed, you could use a jQuery plugin to have a custom alert.

That looks like it should stop the service when you uncheck the checkbox. Are there any exceptions in the log? stopService returns a boolean indicating whether or not it was able to stop the service.

If you are starting your service by Intents, then you may want to extend IntentService instead of Service. That class will stop the service on its own when it has no more work to do.

AutoService

class AutoService extends IntentService {
     private static final String TAG = "AutoService";
     private Timer timer;    
     private TimerTask task;

     public onCreate() {
          timer = new Timer();
          timer = new TimerTask() {
            public void run() 
            {
                System.out.println("done");
            }
          }
     }

     protected void onHandleIntent(Intent i) {
        Log.d(TAG, "onHandleIntent");     

        int delay = 5000; // delay for 5 sec.
        int period = 5000; // repeat every sec.


        timer.scheduleAtFixedRate(timerTask, delay, period);
     }

     public boolean stopService(Intent name) {
        // TODO Auto-generated method stub
        timer.cancel();
        task.cancel();
        return super.stopService(name);
    }

}

This error can also happen if the variable you are comparing has hidden characters that are not numbers/digits.

For example, if you are retrieving an integer from a third-party script, you must ensure that the returned string does not contain hidden characters, like "\n" or "\r".

For example:

#!/bin/bash

# Simulate an invalid number string returned
# from a script, which is "1234\n"
a='1234
'

if [ "$a" -gt 1233 ] ; then
    echo "number is bigger"
else
    echo "number is smaller"
fi

This will result in a script error : integer expression expected because $a contains a non-digit newline character "\n". You have to remove this character using the instructions here: How to remove carriage return from a string in Bash

So use something like this:

#!/bin/bash

# Simulate an invalid number string returned
# from a script, which is "1234\n"
a='1234
'

# Remove all new line, carriage return, tab characters
# from the string, to allow integer comparison
a="${a//[$'\t\r\n ']}"

if [ "$a" -gt 1233 ] ; then
    echo "number is bigger"
else
    echo "number is smaller"
fi

You can also use set -xv to debug your bash script and reveal these hidden characters. See https://www.linuxquestions.org/questions/linux-newbie-8/bash-script-error-integer-expression-expected-934465/

The problem is that git by default using the "Linux" crypto backend.

Beginning with Git for Windows 2.14, you can now configure Git to use SChannel, the built-in Windows networking layer as the crypto backend. This means that you it will use the Windows certificate storage mechanism and you do not need to explicitly configure the curl CA storage mechanism: https://msdn.microsoft.com/en-us/library/windows/desktop/aa380123(v=vs.85).aspx

Just execute:

git config --global http.sslbackend schannel

That should helps.

Using schannel is by now the standard setting when installing git for windows, also it is recommended to not checkout repositories by SSH anmore if possible, as https is easier to configure and less likely to be blocked by a firewall it means less chance of failure.

If the date needs to be the same across all time zones, for example represents some value from the database, then be sure to use UTC versions of the day, month, fullyear functions on the JavaScript date object as this will display in UTC time and avoid off-by-one errors in certain time zones.

Even better, use the Moment.js date library for this sort of formatting.

While solution given by thclpr works it scans only immediate files in the directory and not files in the sub directories if any. Although this is not the requirement but just in case someone wishes to scan sub directories too below is the code that uses os.walk

import os
from glob import glob
PATH = "/home/someuser/projects/someproject"
EXT = "*.csv"
all_csv_files = [file
                 for path, subdir, files in os.walk(PATH)
                 for file in glob(os.path.join(path, EXT))]
print(all_csv_files)

The error about well-formed XML on the root level should disappear (though there may be other issues).

Simple Steps:

Step 1: Click on Create new File

Step 2: Enter the folder name that you want, then press /

Step 3: Enter a sample file name. You must enter some text.

Step 4: Click Commit new file to create the folder

Step 5: Your folder is created!

 $('elements-to-match').click(function(){
        alert("The id is "+ this.id );
    });

no need to wrap it in a jquery object

Assuming that your List is a list of strings make data an ArrayList<String> and use intent.putStringArrayListExtra("data", data)

Here is a skeleton of the code you need:

1. Declare List

   private List<String> test;
   

2. Init List at appropriate place

   test = new ArrayList<String>();
   

   and add data as appropriate to test.

3. Pass to intent as follows:

   Intent intent = getIntent();  
   intent.putStringArrayListExtra("test", (ArrayList<String>) test);
   

4. Retrieve data as follows:

   ArrayList<String> test = getIntent().getStringArrayListExtra("test");
   

Hope that helps.

A HashSet has an internal structure (hash), where items can be searched and identified quickly. The downside is that iterating through a HashSet (or getting an item by index) is rather slow.

So why would someone want be able to know if an entry already exists in a set?

One situation where a HashSet is useful is in getting distinct values from a list where duplicates may exist. Once an item is added to the HashSet it is quick to determine if the item exists (Contains operator).

Other advantages of the HashSet are the Set operations: IntersectWith, IsSubsetOf, IsSupersetOf, Overlaps, SymmetricExceptWith, UnionWith.

If you are familiar with the object constraint language then you will identify these set operations. You will also see that it is one step closer to an implementation of executable UML.

Limelight I really enjoy the theatre metaphor.

It seems to be a python bug (that works perfectly in vim). The source of the problem is the (\s*...)+ bit. Basically , you can't do (\s*)+ which make sense , because you are trying to repeat something which can be null.

>>> re.compile(r"(\s*)+")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/System/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/re.py", line 180, in compile
    return _compile(pattern, flags)
  File "/System/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/re.py", line 233, in _compile
    raise error, v # invalid expression
sre_constants.error: nothing to repeat

However (\s*\1) should not be null, but we know it only because we know what's in \1. Apparently python doesn't ... that's weird.

I would like to stress that, even if there are situations where if expr : isn't sufficient because one wants to make sure expr is True and not just different from 0/None/whatever, is is to be prefered from == for the same reason S.Lott mentionned for avoiding == None.

It is indeed slightly more efficient and, cherry on the cake, more human readable.

The error message proved to be true as Apache Ant isn't in the path of Mac OS X Mavericks anymore.

Bulletproof solution:

1. Download and install Homebrew by executing following command in terminal:

   ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

2. Install Apache Ant via Homebrew by executing

   brew install ant

Run the PhoneGap build again and it should successfully compile and install your Android app.

Keep in mind that it's the user that is running the oracle database that must have write permissions to the /defaultdir directory, not the user logged into oracle. Typically you're running the database as the user "Oracle". It's not the same user (necessarily) that you created the external table with.

Check your directory permissions, too.

Add all the strings to a dictionary and get the Keys property afterwards. This will produce each unique string, but not necessarily in the same order your original input had them in.

If you require the end result to have the same order as the original input, when you consider the first occurance of each string, use the following algorithm instead:

1. Have a list (final output) and a dictionary (to check for duplicates)
2. For each string in the input, check if it exists in the dictionary already
3. If not, add it both to the dictionary and to the list

At the end, the list contains the first occurance of each unique string.

Make sure you consider things like culture and such when constructing your dictionary, to make sure you handle duplicates with accented letters correctly.

Yes, you can use find_elements_by_ to retrieve children elements into a list. See the python bindings here: http://selenium-python.readthedocs.io/locating-elements.html

Example HTML:

<ul class="bar">
    <li>one</li>
    <li>two</li>
    <li>three</li>
</ul>

You can use the find_elements_by_ like so:

parentElement = driver.find_element_by_class_name("bar")
elementList = parentElement.find_elements_by_tag_name("li")

If you want help with a specific case, you can edit your post with the HTML you're looking to get parent and children elements from.

You can also use

lblExamlple.ForeColor = System.Drawing.Color.FromArgb(0,255,0);

Local variables are automatically freed when the function ends, you don't need to free them by yourself. You only free dynamically allocated memory (e.g using malloc) as it's allocated on the heap:

char *arr = malloc(3 * sizeof(char));
strcpy(arr, "bo");
// ...
free(arr);

Since Python 3.6 there is a method choices from the random module.

Python 3.6.1 (v3.6.1:69c0db5050, Mar 21 2017, 01:21:04)
Type 'copyright', 'credits' or 'license' for more information
IPython 6.0.0 -- An enhanced Interactive Python. Type '?' for help.

In [1]: import random

In [2]: random.choices(
...:     population=[['a','b'], ['b','a'], ['c','b']],
...:     weights=[0.2, 0.2, 0.6],
...:     k=10
...: )

Out[2]:
[['c', 'b'],
 ['c', 'b'],
 ['b', 'a'],
 ['c', 'b'],
 ['c', 'b'],
 ['b', 'a'],
 ['c', 'b'],
 ['b', 'a'],
 ['c', 'b'],
 ['c', 'b']]

Note that random.choices will sample with replacement, per the docs:

Return a k sized list of elements chosen from the population with replacement.

Note for completeness of answer:

When a sampling unit is drawn from a finite population and is returned to that population, after its characteristic(s) have been recorded, before the next unit is drawn, the sampling is said to be "with replacement". It basically means each element may be chosen more than once.

If you need to sample without replacement, then as @ronan-paixão's brilliant answer states, you can use numpy.choice, whose replace argument controls such behaviour.

Since you know how many pixels are occupied by the previous content, you can use the calc() function:

height: calc(100% - 50px);

And the jquery version:

$('input').attr('required', true)
$('input').attr('required', false)

I know it's beyond the question, but maybe someone will find this helpful :)

The accepted anwser using cmd.exe and

for /F "tokens=*" %F in (file.txt) do whatever "%F" ...

works only for "normal" files. It fails miserably with huge files.

For big files, you may need to use Powershell and something like this:

[IO.File]::ReadLines("file.txt") | ForEach-Object { whatever "$_" }

or if you have enough memory:

foreach($line in [System.IO.File]::ReadLines("file.txt")) { whatever "$line" } 

This worked for me with a 250 MB file containing over 2 million lines, where the for /F ... command got stuck after a few thousand lines.

For the differences between foreach and ForEach-Object, see Getting to Know ForEach and ForEach-Object.

Disabled controls cannot be successful, and a successful control is "valid" for submission. This is the reason why disabled controls don't submit with the form.

Go into Xcode 12 preferences Click locations Select Xcode 12 for Developer tools/command line tools Install cocoapods for Xcode 12: sudo gem install cocoapods

You can try this

var scroll=$('#scroll');
scroll.animate({scrollTop: scroll.prop("scrollHeight")});

If you have the environment variables in an env.sh locally and want to set it up when the container starts, you could try

COPY env.sh /env.sh
COPY <filename>.jar /<filename>.jar
ENTRYPOINT ["/bin/bash" , "-c", "source /env.sh && printenv && java -jar /<filename>.jar"]

This command would start the container with a bash shell (I want a bash shell since source is a bash command), sources the env.sh file(which sets the environment variables) and executes the jar file.

The env.sh looks like this,

#!/bin/bash
export FOO="BAR"
export DB_NAME="DATABASE_NAME"

I added the printenv command only to test that actual source command works. You should probably remove it when you confirm the source command works fine or the environment variables would appear in your docker logs.

Reflection allows instantiation of new objects, invocation of methods, and get/set operations on class variables dynamically at run time without having prior knowledge of its implementation.

Class myObjectClass = MyObject.class;
Method[] method = myObjectClass.getMethods();

//Here the method takes a string parameter if there is no param, put null.
Method method = aClass.getMethod("method_name", String.class); 

Object returnValue = method.invoke(null, "parameter-value1");

In above example the null parameter is the object you want to invoke the method on. If the method is static you supply null. If the method is not static, then while invoking you need to supply a valid MyObject instance instead of null.

Reflection also allows you to access private member/methods of a class:

public class A{

  private String str= null;

  public A(String str) {
  this.str= str;
  }
}

.

A obj= new A("Some value");

Field privateStringField = A.class.getDeclaredField("privateString");

//Turn off access check for this field
privateStringField.setAccessible(true);

String fieldValue = (String) privateStringField.get(obj);
System.out.println("fieldValue = " + fieldValue);

• For inspection of classes (also know as introspection) you don't need to import the reflection package (java.lang.reflect). Class metadata can be accessed through java.lang.Class.

Reflection is a very powerful API but it may slow down the application if used in excess, as it resolves all the types at runtime.

Add an input id to the element and do something like that:

document.getElementById('inputId').value.split(/[\\$]/).pop()

Extract characters from a string:

var str = "Hello world!";
var res = str.substring(1,4);

The result of res will be:

ell

http://www.w3schools.com/jsref/jsref_substring.asp

$('.dep_buttons').mouseover(function(){
    $(this).text().substring(0,25);
    if($(this).text().length > 30) {
        $(this).stop().animate({height:"150px"},150);
    }
    $(".dep_buttons").mouseout(function(){
        $(this).stop().animate({height:"40px"},150);
    });
});

this should work

 .navbar-nav {
    position: absolute;
    left: 50%;
    transform: translatex(-50%);
}

You just need to put [(ngModel)] on your select element:

<select class="form-control col-lg-8" #corporation required [(ngModel)]="selectedValue">

An app is available that demonstrates a listview that combines both swiping-to-delete and dragging to reorder items. The code is based on Chet Haase's code for swiping-to-delete and Daniel Olshansky's code for dragging-to-reorder.

Chet's code deletes an item immediately. I improved on this by making it function more like Gmail where swiping reveals a bottom view that indicates that the item is deleted but provides an Undo button where the user has the possibility to undo the deletion. Chet's code also has a bug in it. If you have less items in the listview than the height of the listview is and you delete the last item, the last item appears to not be deleted. This was fixed in my code.

Daniel's code requires pressing long on an item. Many users find this unintuitive as it tends to be a hidden function. Instead, I modified the code to allow for a "Move" button. You simply press on the button and drag the item. This is more in line with the way the Google News app works when you reorder news topics.

The source code along with a demo app is available at: https://github.com/JohannBlake/ListViewOrderAndSwipe

Chet and Daniel are both from Google.

Chet's video on deleting items can be viewed at: https://www.youtube.com/watch?v=YCHNAi9kJI4

Daniel's video on reordering items can be viewed at: https://www.youtube.com/watch?v=_BZIvjMgH-Q

A considerable amount of work went into gluing all this together to provide a seemless UI experience, so I'd appreciate a Like or Up Vote. Please also star the project in Github.

As an aside, it is always a good practice (and possibly a solution for this type of issue) to delete a large number of rows by using batches:

WHILE EXISTS (SELECT 1 
              FROM   YourTable 
              WHERE  <yourCondition>) 
  DELETE TOP(10000) FROM YourTable 
  WHERE  <yourCondition>

At the PSQL prompt, you can do:

\connect (or \c) dbname

I have run into problems in the past with IE and the css:hover selector so the approach that I have taken, is to use a custom directive.

.directive('hoverClass', function () {
    return {
        restrict: 'A',
        scope: {
            hoverClass: '@'
        },
        link: function (scope, element) {
            element.on('mouseenter', function() {
                element.addClass(scope.hoverClass);
            });
            element.on('mouseleave', function() {
                element.removeClass(scope.hoverClass);
            });
        }
    };
})

then on the element itself you can add the directive with the class names that you want enabled when the mouse is over the the element for example:

<li data-ng-repeat="item in social" hover-class="hover tint" class="social-{{item.name}}" ng-mouseover="hoverItem(true);" ng-mouseout="hoverItem(false);"
                index="{{$index}}"><i class="{{item.icon}}"
                box="course-{{$index}}"></i></li>

This should add the class hover and tint when the mouse is over the element and doesn't run the risk of a scope variable name collision. I haven't tested but the mouseenter and mouseleave events should still bubble up to the containing element so in the given scenario the following should still work

<div hover-class="hover" data-courseoverview data-ng-repeat="course in courses | orderBy:sortOrder | filter:search"
 data-ng-controller ="CourseItemController"
 data-ng-class="{ selected: isSelected }">

providing of course that the li's are infact children of the parent div

This can get really cool with an extension (functioning as a proxy), for example:

collection.SelectWithIndex(); 
// vs. 
collection.Select((item, index) => item);

Which will automagically assign indexes to the collection accessible via this Index property.

Interface:

public interface IIndexable
{
    int Index { get; set; }
}

Custom extension (probably most useful for working with EF and DbContext):

public static class EnumerableXtensions
{
    public static IEnumerable<TModel> SelectWithIndex<TModel>(
        this IEnumerable<TModel> collection) where TModel : class, IIndexable
    {
        return collection.Select((item, index) =>
        {
            item.Index = index;
            return item;
        });
    }
}

public class SomeModelDTO : IIndexable
{
    public Guid Id { get; set; }
    public string Name { get; set; }
    public decimal Price { get; set; }

    public int Index { get; set; }
}

// In a method
var items = from a in db.SomeTable
            where a.Id == someValue
            select new SomeModelDTO
            {
                Id = a.Id,
                Name = a.Name,
                Price = a.Price
            };

return items.SelectWithIndex()
            .OrderBy(m => m.Name)
            .Skip(pageStart)
            .Take(pageSize)
            .ToList();

The answers posted here all didn't quite work for me. They mainly skipped signing embedded frameworks (or including the entitlements).

Here's what's worked for me (it assumes that one ipa file exists is in the current directory):

PROVISION="/path/to/file.mobileprovision"
CERTIFICATE="Name of certificate: To sign with" # must be in the keychain

unzip -q *.ipa
rm -rf Payload/*.app/_CodeSignature/

# Replace embedded provisioning profile
cp "$PROVISION" Payload/*.app/embedded.mobileprovision

# Extract entitlements from app
codesign -d --entitlements :entitlements.plist Payload/*.app/

# Re-sign embedded frameworks
codesign -f -s "$CERTIFICATE" --entitlements entitlements.plist Payload/*.app/Frameworks/*

# Re-sign the app (with entitlements)
codesign -f -s "$CERTIFICATE" --entitlements entitlements.plist Payload/*.app/

zip -qr resigned.ipa Payload

# Cleanup
rm entitlements.plist
rm -r Payload/

SQL Locator (free) has worked great for me. It comes with a lot of options and it's fairly easy to use.

With Java Generics Takes a list of X and returns a list of T that extends or implements X, Sweet!

    // the cast is is actually checked via the method API
@SuppressWarnings("unchecked")
public static <T extends X, X> ArrayList<T> convertToClazz(ArrayList<X> from, Class<X> inClazz, Class<T> outClazz) {
    ArrayList<T> to = new ArrayList<T>();
    for (X data : from) {
        to.add((T) data);
    }
    return to;
}

Add this to the beginning of the script:

set -e

This will cause the shell to exit immediately if a simple command exits with a nonzero exit value. A simple command is any command not part of an if, while, or until test, or part of an && or || list.

See the bash(1) man page on the "set" internal command for more details.

I personally start almost all shell scripts with "set -e". It's really annoying to have a script stubbornly continue when something fails in the middle and breaks assumptions for the rest of the script.

Couple of points:

• I believe git stash + git stash drop could be replaced with git reset --hard

• ... or, even shorter, add -f to checkout command:

  git checkout -f -b $branch
  

  That will discard any local changes, just as if git reset --hard was used prior to checkout.

As for the main question: instead of pulling in the last step, you could just merge the appropriate branch from the remote into your local branch: git merge $branch origin/$branch, I believe it does not hit the remote. If that is the case, it removes the need for credensials and hence, addresses your biggest concern.

1. open my.cnf and copy the log-error path

2. then check the permission for the copied log file using
   $ ls -l /var/log/mysql.log

3. if any log file permission may changed from mysql:mysql, please change the file permission to
   $ chown -R mysql:mysql /var/log/mysql.log

4. then restart the mysql server
   $ service mysql restart || systemctl restart mysqld

note: this kind of errors formed by the permission issues. all the mysql service start commands using the log file for writing the status of mysql. If the permission has been changed, the service can't be write anything into the log files. If it happens it will stopped to run the service

For some non-activity classes, like Worker, you're already given a Context object in the public constructor.

Worker(Context context, WorkerParameters workerParams)

You can just use that, e.g., save it to a private Context variable in the class (say, mContext), and then, for example

mContext.getSystenService(Context.ACTIVITY_SERVICE)

Another way would be using:

myCursor.getCount();

on a Cursor like:

Cursor myCursor = db.query(table_Name, new String[] { row_Username }, 
row_Username + " =? AND " + row_Password + " =?",
new String[] { entered_Password, entered_Password }, 
null, null, null);

If you can think of getting away from the raw query.

The pyplot functions you are calling, axhline() and axvline() draw lines that span a portion of the axis range, regardless of coordinates. The parameters xmin or ymin use value 0.0 as the minimum of the axis and 1.0 as the maximum of the axis.

Instead, use plt.plot((x1, x2), (y1, y2), 'k-') to draw a line from the point (x1, y1) to the point (x2, y2) in color k. See pyplot.plot.

Without using itertools:

In Python 3 you can use yield from to add a subset generator method to buit-in set class:

class SetWithSubset(set):
    def subsets(self):
        s1 = []
        s2 = list(self)

        def recfunc(i=0):            
            if i == len(s2):
                yield frozenset(s1)
            else:                
                yield from recfunc(i + 1)
                s1.append(s2[ i ])
                yield from recfunc(i + 1)
                s1.pop()

        yield from recfunc()

For example below snippet works as expected:

x = SetWithSubset({1,2,3,5,6})
{2,3} in x.subsets()            # True
set() in x.subsets()            # True
x in x.subsets()                # True
x|{7} in x.subsets()            # False
set([5,3]) in x.subsets()       # True - better alternative: set([5,3]) < x
len(x.subsets())                # 32

You're performing an integer division. Append a .0 to the number literals:

per=float(tota)*(100.0/500.0)

In Python 2.7 the division 100/500==0.

As pointed out by @unwind, the float() call is superfluous since a multiplication/division by a float returns a float:

per= tota*100.0 / 500

I would suggest using mpld3 which combines D3js javascript visualizations with matplotlib of python.

If you have a UITabController with Screens with Embeded Navigation Controllers, you have to set the UITabController Presentation to FullScreen as shown in pic below

When building TensorFlow from source, you'll run the configure script. One of the questions that the configure script asks is as follows:

Please specify optimization flags to use during compilation when bazel option "--config=opt" is specified [Default is -march=native]

The configure script will attach the flag(s) you specify to the bazel command that builds the TensorFlow pip package. Broadly speaking, you can respond to this prompt in one of two ways:

• If you are building TensorFlow on the same type of CPU type as the one on which you'll run TensorFlow, then you should accept the default (-march=native). This option will optimize the generated code for your machine's CPU type.
• If you are building TensorFlow on one CPU type but will run TensorFlow on a different CPU type, then consider supplying a more specific optimization flag as described in the gcc documentation.

After configuring TensorFlow as described in the preceding bulleted list, you should be able to build TensorFlow fully optimized for the target CPU just by adding the --config=opt flag to any bazel command you are running.

When the preprocessor sees #if it checks whether the next token has a non-zero value. If it does, it keeps the code around for the compiler. If it doesn't, it gets rid of that code so the compiler never sees it.

If someone says #if 0 they are effectively commenting out the code so it will never be compiled. You can think of this the same as if they had put /* ... */ around it. It's not quite the same, but it has the same effect.

If you want to understand what happened in detail, you can often look. Many compilers will allow you to see the files after the preprocessor has run. For example, on Visual C++ the switch /P command will execute the preprocessor and put the results in a .i file.

If you only need the value:

$result = mysql_query("SELECT count(*) from Students;");
echo mysql_result($result, 0);

You can simply open the phpmyadmin page from your browser, then open any existing database -> go to Privileges tab, click on your root user and then a popup window will appear, you can set your password there.. Hope this Helps.

You can use case in update and SWAP as many as you want

update Table SET column=(case when is_row_1 then value_2 else value_1 end) where rule_to_match_swap_columns

If you want a deep copy without override while retaining the same obj reference

obj = _.assign(obj, _.merge(obj, [source]))

            startInfo.Arguments = parameters;
            startInfo.ErrorDialog = true;

            Process process = System.Diagnostics.Process.Start(startInfo);
            process.WaitForExit();
            return process.ExitCode;
        } catch (Win32Exception ex) {

                default:
                    return ErrorReturnInteger;
            }

        } catch (Exception ex) {
            WriteLog(ex);
            return ErrorReturnInteger;
        }
    }

Hope it helps.

git revert -m allows to un-merge still keeping the history of both merge and un-do operation. Might be good for documenting probably.

For .NET Core projects and Visual Studio 2017 I was able to restore all packages to relative path by providing this configuration:

<configuration>
  <config>
    <add key="globalPackagesFolder" value="lib" />
  </config>
  ... 
</configuration>

Based on my experience the lib folder was created on the same level where Nuget.config was found, no matter where sln file was. I tested and the behavior is same for command line dotnet restore, and Visual Studio 2017 rebuild

NOTE: elem is the HTML selector of an element which the page will be scrolled to. Anything supported by jQuery, like: #myid, div.myclass, $(jquery object), [dom object], etc.

jQuery.fn.scrollTo = function(elem, speed) { 
    $(this).animate({
        scrollTop:  $(this).scrollTop() - $(this).offset().top + $(elem).offset().top 
    }, speed == undefined ? 1000 : speed); 
    return this; 
};

If you don't need it to be animated, then use:

jQuery.fn.scrollTo = function(elem) { 
    $(this).scrollTop($(this).scrollTop() - $(this).offset().top + $(elem).offset().top); 
    return this; 
};

How to use:

$("#overflow_div").scrollTo("#innerItem");
$("#overflow_div").scrollTo("#innerItem", 2000); //custom animation speed 

Note: #innerItem can be anywhere inside #overflow_div. It doesn't really have to be a direct child.

Tested in Firefox (23) and Chrome (28).

If you want to scroll the whole page, check this question.

Casting the integer to a char will do what you want.

char theChar=' ';
int theInt = 97;
theChar=(char) theInt;

cout<<theChar<<endl;

There is no difference between 'a' and 97 besides the way you interperet them.

I found the easiest way to locate it, you can use

I feel that MWV (Model View Whatever) or MV* is a more flexible term to describe some of the uniqueness of Angularjs in my opinion. It helped me to understand that it is more than a MVC (Model View Controller) JavaScript framework, but it still uses MVC as it has a Model View, and Controller.

It also can be considered as a MVP (Model View Presenter) pattern. I think of a Presenter as the user-interface business logic in Angularjs for the View. For example by using filters that can format data for display. It's not business logic, but display logic and it reminds me of the MVP pattern I used in GWT.

In addition, it also can be a MVVM (Model View View Model) the View Model part being the two-way binding between the two. Last of all it is MVW as it has other patterns that you can use as well as mentioned by @Steve Chambers.

I agree with the other answers that getting pedantic on these terms can be detrimental, as the point is to understand the concepts from the terms, but by the same token, fully understanding the terms helps one when they are designing their application code, knowing what goes where and why.

This should do the trick

df = data.frame(date=c("2012-02-01", "2012-02-01", "2012-02-02")) 
dow <- function(x) format(as.Date(x), "%A")
df$day <- dow(df$date)
df

#Returns:
        date       day
1 2012-02-01 Wednesday
2 2012-02-01 Wednesday
3 2012-02-02  Thursday

It's important to distinguish between the content of cells, their display format, the data type read from cells by VBA, and the data type written to cells from VBA and how Excel automatically interprets this. (See e.g. this previous answer.) The relationship between these can be a bit complicated, because Excel will do things like interpret values of one type (e.g. string) as being a certain other data type (e.g. date) and then automatically change the display format based on this. Your safest bet it do everything explicitly and not to rely on this automatic stuff.

I ran your experiment and I don't get the same results as you do. My cell A1 stays a Date the whole time, and B1 stays 41575. So I can't answer your question #1. Results probably depend on how your Excel version/settings choose to automatically detect/change a cell's number format based on its content.

Question #2, "How can I ensure that a cell will return a date value": well, not sure what you mean by "return" a date value, but if you want it to contain a numerical value that is displayed as a date, based on what you write to it from VBA, then you can either:

• Write to the cell a string value that you hope Excel will automatically interpret as a date and format as such. Cross fingers. Obviously this is not very robust. Or,

• Write a numerical value to the cell from VBA (obviously a Date type is the intended type, but an Integer, Long, Single, or Double could do as well) and explicitly set the cells' number format to your desired date format using the .NumberFormat property (or manually in Excel). This is much more robust.

If you want to check that existing cell contents can be displayed as a date, then here's a function that will help:

Function CellContentCanBeInterpretedAsADate(cell As Range) As Boolean
    Dim d As Date
    On Error Resume Next
    d = CDate(cell.Value)
    If Err.Number <> 0 Then
        CellContentCanBeInterpretedAsADate = False
    Else
        CellContentCanBeInterpretedAsADate = True
    End If
    On Error GoTo 0
End Function

Example usage:

Dim cell As Range
Set cell = Range("A1")

If CellContentCanBeInterpretedAsADate(cell) Then
    cell.NumberFormat = "mm/dd/yyyy hh:mm"
Else
    cell.NumberFormat = "General"
End If

The default sort is stable, so we sort twice: First by the minor key, then by the major key

rum1 <- rum[order(rum$I2, decreasing = FALSE),]
rum2 <- rum1[order(rum1$I1, decreasing = TRUE),]

First, you declared $db outside the function. If you want to use it inside the function, you should put this at the begining of your function code:

global $db;

And I guess, when you wrote:

if($result->num_rows){
        return (mysqli_result($query, 0) == 1) ? true : false;

what you really wanted was:

if ($result->num_rows==1) { return true; } else { return false; }

I would do the following.

Set the zero to NA.

 data[data==0] <- NA
 data

Delete the rows associated with NA.

 data2<-data[complete.cases(data),]

value="0" will set defualt value for @Html.TextBoxfor

its case sensitive "v" should be capital

Below is working example:

@Html.TextBoxFor(m => m.Nights, 
    new { @min = "1", @max = "10", @type = "number", @id = "Nights", @name = "Nights", Value = "1" })

After five years, I can see this is still a very relevant subject. Somewhat mirroring leucos's answer which I find the best in my case, using ansible tools only (without any centralised authentication, tokens or whatever). This assumes you have the same username and the same public key on all servers. If you don't, of course you'd need to be more specific and add the corresponding variables next to the hosts:

[all:vars]
ansible_ssh_user=ansible
ansible_ssh_private_key_file=home/user/.ssh/mykey
[group]
192.168.0.50 ansible_sudo_pass='{{ myserver_sudo }}'

ansible-vault create mypasswd.yml
ansible-vault edit mypasswd.yml

Add:

myserver_sudo: mysecretpassword

Then:

ansible-playbook -i inv.ini my_role.yml --ask-vault --extra-vars '@passwd.yml'

At least this way you don't have to write more the variables which point to the passwords.

I have found a solution by myself. I use the PDANet tool to find the driver automatically.

\d defines a number and {1,2} means 1 or two of the expression before, \W defines a non word character.

Just as on FYI to others suddenly experiencing this on an otherwise (previously) working Laravel installation:

My Laravel environment is on a Ubuntu VirtualBox hosted on a Win-10 laptop.

I used my phone to share Internet via USB and suddenly started experiencing this issue. I changed to using the phone as wireless hotspot and the issue went away. This is a nameserver/networking issue and is not specific to Laravel or MySQL.

You need to call the AddAddress method once for every recipient. Like so:

$mail->AddAddress('[email protected]', 'Person One');
$mail->AddAddress('[email protected]', 'Person Two');
// ..

Better yet, add them as Carbon Copy recipients.

$mail->AddCC('[email protected]', 'Person One');
$mail->AddCC('[email protected]', 'Person Two');
// ..

To make things easy, you should loop through an array to do this.

$recipients = array(
   '[email protected]' => 'Person One',
   '[email protected]' => 'Person Two',
   // ..
);
foreach($recipients as $email => $name)
{
   $mail->AddCC($email, $name);
}

In my case, It was returning one output parameter and was not Returning any value.
So changed it to

param.Direction = ParameterDirection.Output;
command.ExecuteScalar();

and then it was throwing size error. so had to set the size as well

SqlParameter param = new SqlParameter("@Name",SqlDbType.NVarChar);
param.Size = 10;

Here is my solution it is pretty straight forward since all I care about is not necessarily GCD or even accurate ratios: because then you get weird things like 345/113 which are not human comprehensible.

I basically set acceptable landscape, or portrait ratios and their "value" as a float... I then compare my float version of the ratio to each and which ever has the lowest absolute value difference is the ratio closest to the item. That way when the user makes it 16:9 but then removes 10 pixels from the bottom it still counts as 16:9...

accepted_ratios = {
    'landscape': (
        (u'5:4', 1.25),
        (u'4:3', 1.33333333333),
        (u'3:2', 1.5),
        (u'16:10', 1.6),
        (u'5:3', 1.66666666667),
        (u'16:9', 1.77777777778),
        (u'17:9', 1.88888888889),
        (u'21:9', 2.33333333333),
        (u'1:1', 1.0)
    ),
    'portrait': (
        (u'4:5', 0.8),
        (u'3:4', 0.75),
        (u'2:3', 0.66666666667),
        (u'10:16', 0.625),
        (u'3:5', 0.6),
        (u'9:16', 0.5625),
        (u'9:17', 0.5294117647),
        (u'9:21', 0.4285714286),
        (u'1:1', 1.0)
    ),
}


def find_closest_ratio(ratio):
    lowest_diff, best_std = 9999999999, '1:1'
    layout = 'portrait' if ratio < 1.0 else 'landscape'
    for pretty_str, std_ratio in accepted_ratios[layout]:
        diff = abs(std_ratio - ratio)
        if diff < lowest_diff:
            lowest_diff = diff
            best_std = pretty_str
    return best_std


def extract_ratio(width, height):
    try:
        divided = float(width)/float(height)
        if divided == 1.0: return '1:1'
        return find_closest_ratio(divided)
    except TypeError:

Easy recursive way

int    get_int_lenght(current_lenght, value)
{
 if (value / 10 < 10)
    return (current_lenght + 1);
return (get_int_lenght(current_lenght + 1, value))
}

In spring boot 2.x you need to reference provider specific properties.

The default, hikari can be set with spring.datasource.hikari.maximum-pool-size.

To read a file...

set /P Variable=<File.txt

To Write a file

@echo %DataToWrite%>File.txt

note; having spaces before the <> character causes a space to be added at the end of the variable, also

To add to a file,like a logger program, First make a file with a single enter key in it called e.txt

set /P Data=<log0.log
set /P Ekey=<e.txt
@echo %Data%%Ekey%%NewData%>log0.txt

your log will look like this

Entry1
Entry2 

and so on

If you're using Jackson (the most popular library there), try

https://github.com/astav/JsonToJava

Its open source (last updated on Jun 7, 2013 as of year 2020) and anyone should be able to contribute.

Summary

A JsonToJava source class file generator that deduces the schema based on supplied sample json data and generates the necessary java data structures.

It encourages teams to think in Json first, before writing actual code.

Features

• Can generate classes for an arbitrarily complex hierarchy (recursively)
• Can read your existing Java classes and if it can deserialize into those structures, will do so
• Will prompt for user input when ambiguous cases exist

This page explains it pretty well.

As a numeric the allowable range that can be stored in that field is -10^38 +1 to 10^38 - 1.

The first number in parentheses is the total number of digits that will be stored. Counting both sides of the decimal. In this case 18. So you could have a number with 18 digits before the decimal 18 digits after the decimal or some combination in between.

The second number in parentheses is the total number of digits to be stored after the decimal. Since in this case the number is 0 that basically means only integers can be stored in this field.

So the range that can be stored in this particular field is -(10^18 - 1) to (10^18 - 1)

Or -999999999999999999 to 999999999999999999 Integers only

There are a couple of ways to mock globals in Jest:

1. Use the mockImplementation approach (the most Jest-like way), but it will work only for those variables which has some default implementation provided by jsdom. window.open is one of them:

   test('it works', () => {
     // Setup
     const mockedOpen = jest.fn();
     // Without making a copy, you will have a circular dependency problem
     const originalWindow = { ...window };
     const windowSpy = jest.spyOn(global, "window", "get");
     windowSpy.mockImplementation(() => ({
       ...originalWindow, // In case you need other window properties to be in place
       open: mockedOpen
     }));
   
     // Tests
     statementService.openStatementsReport(111)
     expect(mockedOpen).toBeCalled();
   
     // Cleanup
     windowSpy.mockRestore();
   });
   

2. Assign the value directly to the global property. It is the most straightforward, but it may trigger error messages for some window variables, e.g. window.href.

   test('it works', () => {
     // Setup
     const mockedOpen = jest.fn();
     const originalOpen = window.open;
     window.open = mockedOpen;
   
     // Tests
     statementService.openStatementsReport(111)
     expect(mockedOpen).toBeCalled();
   
     // Cleanup
     window.open = originalOpen;
   });
   

3. Don't use globals directly (requires a bit of refactoring)

   Instead of using the global value directly, it might be cleaner to import it from another file, so mocking will became trivial with Jest.

File ./test.js

jest.mock('./fileWithGlobalValueExported.js');
import { windowOpen } from './fileWithGlobalValueExported.js';
import { statementService } from './testedFile.js';

// Tests
test('it works', () => {
  statementService.openStatementsReport(111)
  expect(windowOpen).toBeCalled();
});

File ./fileWithGlobalValueExported.js

export const windowOpen = window.open;

File ./testedFile.js

import { windowOpen } from './fileWithGlobalValueExported.js';
export const statementService = {
  openStatementsReport(contactIds) {
    windowOpen(`a_url_${contactIds}`);
  }
}

Maybe you received an error when working with this table before. You can rename the table and try to remove it again.

ALTER TABLE `area` RENAME TO `area2`;
DROP TABLE IF EXISTS `area2`;

I've given up trying to align my text on buttons! Now, if I need it, I'm using <a> tags, like so:

<a href="javascript:void();" style="display:block;font-size:1em;padding:5px;cursor:default;" onclick="document.getElementById('form').submit();">Submit</a>

So, if the document's font size is 12px, my "button" will have 22px height. And the text will be vertically align. That in theory, because, in some casses, an unequal padding of "6px 5px 4px 5px" will do the job done.

Although, is a hack, this technique is pretty good for solving compatibility issues in older browsers too, like IE6!

I run this test in the Chrome console. Using (void 0) you can check undefined:

var c;
undefined
if (c === void 0) alert();
// output =  undefined
var c = 1;
// output =  undefined
if (c === void 0) alert();
// output =   undefined
// check c value  c
// output =  1
if (c === void 0) alert();
// output =  undefined
c = undefined;
// output =  undefined
if (c === void 0) alert();
// output =   undefined

Just use pandas

list(pd.DataFrame(listofstuff).melt().values)

this only works for a list of lists

if you have a list of list of lists you might want to try something along the lines of

lists(pd.DataFrame(listofstuff).melt().apply(pd.Series).melt().values)

use --cacert to specify a .crt file. ca-root-nss.crt for example.

Try WebClient.DownloadFileAsync(). You can call CancelAsync() by timer with your own timeout.

You could use getopt.

 #include <ctype.h>
 #include <stdio.h>
 #include <stdlib.h>
 #include <unistd.h>

 int
 main (int argc, char **argv)
 {
   int bflag = 0;
   int sflag = 0;
   int index;
   int c;

   opterr = 0;

   while ((c = getopt (argc, argv, "bs")) != -1)
     switch (c)
       {
       case 'b':
         bflag = 1;
         break;
       case 's':
         sflag = 1;
         break;
       case '?':
         if (isprint (optopt))
           fprintf (stderr, "Unknown option `-%c'.\n", optopt);
         else
           fprintf (stderr,
                    "Unknown option character `\\x%x'.\n",
                    optopt);
         return 1;
       default:
         abort ();
       }

   printf ("bflag = %d, sflag = %d\n", bflag, sflag);

   for (index = optind; index < argc; index++)
     printf ("Non-option argument %s\n", argv[index]);
   return 0;
 }

Have a look at the rack-cors middleware. It will handle CORS headers in a configurable manner.

setInterval sets up a recurring timer. It returns a handle that you can pass into clearInterval to stop it from firing:

var handle = setInterval(drawAll, 20);

// When you want to cancel it:
clearInterval(handle);
handle = 0; // I just do this so I know I've cleared the interval

On browsers, the handle is guaranteed to be a number that isn't equal to 0; therefore, 0 makes a handy flag value for "no timer set". (Other platforms may return other values; NodeJS's timer functions return an object, for instance.)

To schedule a function to only fire once, use setTimeout instead. It won't keep firing. (It also returns a handle you can use to cancel it via clearTimeout before it fires that one time if appropriate.)

setTimeout(drawAll, 20);

From matplotlib 3.1 onwards you can use .legend_elements(). An example is shown in Automated legend creation. The advantage is that a single scatter call can be used.

In this case:

import numpy as np
import pandas as pd
import matplotlib.pyplot as plt

df = pd.DataFrame(np.random.normal(10,1,30).reshape(10,3), 
                  index = pd.date_range('2010-01-01', freq = 'M', periods = 10), 
                  columns = ('one', 'two', 'three'))
df['key1'] = (4,4,4,6,6,6,8,8,8,8)


fig, ax = plt.subplots()
sc = ax.scatter(df['one'], df['two'], marker = 'o', c = df['key1'], alpha = 0.8)
ax.legend(*sc.legend_elements())
plt.show()

In case the keys were not directly given as numbers, it would look as

import numpy as np
import pandas as pd
import matplotlib.pyplot as plt

df = pd.DataFrame(np.random.normal(10,1,30).reshape(10,3), 
                  index = pd.date_range('2010-01-01', freq = 'M', periods = 10), 
                  columns = ('one', 'two', 'three'))
df['key1'] = list("AAABBBCCCC")

labels, index = np.unique(df["key1"], return_inverse=True)

fig, ax = plt.subplots()
sc = ax.scatter(df['one'], df['two'], marker = 'o', c = index, alpha = 0.8)
ax.legend(sc.legend_elements()[0], labels)
plt.show()

Perhaps the best two browser techs for this are Canvas, with Flash as a back up.

We tried VML on IE as backup for Canvas, but it was much slower than Flash. SVG was slower then all the rest.

With jSignature ( http://willowsystems.github.com/jSignature/ ) we used Canvas as primary, with fallback to Flash-based Canvas emulator (FlashCanvas) for IE8 and less. Id' say worked very well for us.

Actually, I figured it out myself that I could do this:

while (rdr.read())
{  
  string str = rdr.GetValue().ToString().Trim();  
}

Get path work with all OS

var filename = $('input[type=file]').val().replace(/.*(\/|\\)/, '');

Example

C:\fakepath\filename.doc 
/var/fakepath/filename.doc

Both return

filename.doc
filename.doc

Copy all file and replace to /var/lib/mysql , after that you must change owner of files to mysql this is so important if mariadb.service restart has been faild

chown -R mysql:mysql /var/lib/mysql/*

and

chmod -R 700 /var/lib/mysql/*

You can use Length annotation for a column. By using it you can maximize or minimize column length. Length annotation only be used for Strings.

@Column(name = "NAME", nullable = false, length = 50)  
@Length(max = 50)
public String getName() {
    return this.name;
}

I have copied your code and it runs fine.

I suspect you are simply having some problem in the actual file name of hello.txt, or you are running in a wrong directory. Consider verifying by the method suggested by @Eng.Fouad

As others have hinted, you should consider dumping org.json's library. It's pretty much obsolete these days, and trying to work around its problems is waste of time.

But to specific question; type variable T just does not have any information to help you, as it is little more than compile-time information. Instead you need to pass actual class (as 'Class cls' argument), and you can then create an instance with 'cls.newInstance()'.

I also ran into this all of a sudden, after it had previously worked, and it was because I was inside a virtualenv, and wheel wasn’t installed in the virtualenv.

If you want to create full path without extension you can do something like this:

Path.Combine( Path.GetDirectoryName(fullPath), Path.GetFileNameWithoutExtension(fullPath))

but I'm looking for simpler way to do that. Does anyone have any idea?

For those coming to this with similar problems, this request library allows you to make external http requests seemlessly within your php application. Simplified GET, POST, PATCH, DELETE and PUT requests.

A sample request would be as below

use Libraries\Request;

$data = [
  'samplekey' => 'value',
  'otherkey' => 'othervalue'
];

$headers = [
  'Content-Type' => 'application/json',
  'Content-Length' => sizeof($data)
];

$response = Request::post('https://example.com', $data, $headers);
// the $response variable contains response from the request

Documentation for the same can be found in the project's README.md

Example

  [class*='section-']:not(.section-name) {
    @include opacity(0.6);
    // Write your css code here
  }

// Opacity 0.6 all "section-" but not "section-name"

You could search for:

<li><a href="#">[^\n]+

And replace with:

$0</a>

Where $0 is the whole match. The exact semantics will depend on the language are you using though.

To get the remote ip address the quickest way possible. You must have to use a downloader, or create a server on your computer.

The downsides to using this simple code: (which is recommended) is that it will take 3-5 seconds to get your Remote IP Address because the WebClient when initialized always takes 3-5 seconds to check for your proxy settings.

            string externalIP = "";
            externalIP = new WebClient().DownloadString("http://checkip.dyndns.org/");
            externalIP = (new Regex(@"\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}"))
                                           .Matches(externalIP)[0].ToString();
            return externalIP;
 }

Here is how I fixed it.. (first time still takes 3-5 seconds) but after that it will always get your Remote IP Address in 0-2 seconds depending on your connection.

public static WebClient webclient = new WebClient();
public static string GetIP()
{
    string externalIP = "";
    externalIP = webclient.DownloadString("http://checkip.dyndns.org/");
    externalIP = (new Regex(@"\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}"))
                                   .Matches(externalIP)[0].ToString();
    return externalIP;
}

I think you have to add grunt to your package.json file. See this link.

You can do it. That is what big guys do as well.

As you see, the list of IPs rotated around, but the relative order between two IPs stayed the same.

Update: I see several comments bragging about how DNS round-robin is not convenient for fail-over, so here is the summary: DNS is not for fail-over. So it is obviously not good for fail-over. It was never designed to be a solution for fail-over.

Git has two types of branches: local and remote. To use git pull and git push as you'd like, you have to tell your local branch (my_test) which remote branch it's tracking. In typical Git fashion this can be done in both the config file and with commands.

Commands

Make sure you're on your master branch with

1)git checkout master

then create the new branch with

2)git branch --track my_test origin/my_test

and check it out with

3)git checkout my_test.

You can then push and pull without specifying which local and remote.

However if you've already created the branch then you can use the -u switch to tell git's push and pull you'd like to use the specified local and remote branches from now on, like so:

git pull -u my_test origin/my_test
git push -u my_test origin/my_test

Config

The commands to setup remote branch tracking are fairly straight forward but I'm listing the config way as well as I find it easier if I'm setting up a bunch of tracking branches. Using your favourite editor open up your project's .git/config and add the following to the bottom.

[remote "origin"]
    url = [email protected]:username/repo.git
    fetch = +refs/heads/*:refs/remotes/origin/*
[branch "my_test"]
    remote = origin
    merge = refs/heads/my_test

This specifies a remote called origin, in this case a GitHub style one, and then tells the branch my_test to use it as it's remote.

You can find something very similar to this in the config after running the commands above.

Some useful resources:

• http://www.kernel.org/pub/software/scm/git/docs/git-branch.html

I had quite a bit of trouble as I didn't want to FIX the overlay in place as I wanted the info inside the overlay to be scrollable over the text. I used:

<html style="height=100%">
   <body style="position:relative">
      <div id="my-awesome-overlay" 
           style="position:absolute; 
                  height:100%; 
                  width:100%; 
                  display: block">
           [epic content here]
      </div>
   </body>
</html>

Of course the div in the middle needs some content and probably a transparent grey background but I'm sure you get the gist!

I believe the standard MIME type for Excel files is application/vnd.ms-excel.

Regarding the name of the document, you should set the following header in the response:

header('Content-Disposition: attachment; filename="name_of_excel_file.xls"');

In ES6, you can do like this.

var key = "name";
var person = {[key]:"John"}; // same as var person = {"name" : "John"}
console.log(person); // should print  Object { name="John"}

    var key = "name";_x000D_
    var person = {[key]:"John"};_x000D_
    console.log(person); // should print  Object { name="John"}

Its called Computed Property Names, its implemented using bracket notation( square brackets) []

Example: { [variableName] : someValue }

Starting with ECMAScript 2015, the object initializer syntax also supports computed property names. That allows you to put an expression in brackets [], that will be computed and used as the property name.

For ES5, try something like this

var yourObject = {};

yourObject[yourKey] = "yourValue";

console.log(yourObject );

example:

var person = {};
var key = "name";

person[key] /* this is same as person.name */ = "John";

console.log(person); // should print  Object { name="John"}

    var person = {};_x000D_
    var key = "name";_x000D_
    _x000D_
    person[key] /* this is same as person.name */ = "John";_x000D_
    _x000D_
    console.log(person); // should print  Object { name="John"}

It generally comes to mind that you have set up two-factor authentication, after a few password trials and maybe a password reset. So, how can we git clone a private repository using two-factor authentication? It is simple, using access tokens.

How to Authenticate Git using Access Tokens

1. Go to https://github.com/settings/tokens
2. Click Generate New Token button on top right.
3. Give your token a descriptive name.
4. Set all required permissions for the token.
5. Click Generate token button at the bottom.
6. Copy the generated token to a safe place.
7. Use this token instead of password when you use git clone.

Wow, it works!

Your onclick fires before the href so it will change before the page is opened, you need to make the function handle the window opening like so:

function changeLink() {
    var link = document.getElementById("mylink");

    window.open(
      link.href,
      '_blank'
    );

    link.innerHTML = "facebook";
    link.setAttribute('href', "http://facebook.com");

    return false;
}

To work only chrome or safari, try it:

@media screen and (-webkit-min-device-pixel-ratio:0) { 
/* Safari and Chrome */
.myClass {
 color:red;
}

/* Safari only override */
::i-block-chrome,.myClass {
 color:blue;
}}

Very common problem in android
It can be broken down into 3 Pieces
1 ) start Activity B (Happens in Activity A)
2 ) Set requested data (Happens in activity B)
3 ) Receive requested data (Happens in activity A)

1) startActivity B

Intent i = new Intent(A.this, B.class);
startActivity(i);

2) Set requested data

In this part, you decide whether you want to send data back or not when a particular event occurs.
Eg: In activity B there is an EditText and two buttons b1, b2.
Clicking on Button b1 sends data back to activity A
Clicking on Button b2 does not send any data.

Sending data

b1......clickListener
{
   Intent resultIntent = new Intent();
   resultIntent.putExtra("Your_key","Your_value");
   setResult(RES_CODE_A,resultIntent);
   finish();
}

Not sending data

b2......clickListener
    {
       setResult(RES_CODE_B,new Intent());
       finish();
    }

user clicks back button
By default, the result is set with Activity.RESULT_CANCEL response code

3) Retrieve result

For that override onActivityResult method

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);

if (resultCode == RES_CODE_A) {

     // b1 was clicked 
   String x = data.getStringExtra("RES_CODE_A");

}
else if(resultCode == RES_CODE_B){

   // b2 was clicked

}
else{
   // back button clicked 
}
}

As the question is asked years ago, and Android is evolved a lot on this URI scheme.
From original URI scheme, to deep link, and now Android App Links.

Android now recommends to use HTTP URLs, not define your own URI scheme. Because Android App Links use HTTP URLs that link to a website domain you own, so no other app can use your links. You can check the comparison of deep link and Android App links from here

Now you can easily add a URI scheme by using Android Studio option: Tools > App Links Assistant. Please refer the detail to Android document: https://developer.android.com/studio/write/app-link-indexing.html

If you want to build on top of ScriptControl, you can add a few helper method to get at the required information. The JScriptTypeInfo object is a bit unfortunate: it contains all the relevant information (as you can see in the Watch window) but it seems impossible to get at it with VBA. However, the Javascript engine can help us:

Option Explicit

Private ScriptEngine As ScriptControl

Public Sub InitScriptEngine()
    Set ScriptEngine = New ScriptControl
    ScriptEngine.Language = "JScript"
    ScriptEngine.AddCode "function getProperty(jsonObj, propertyName) { return jsonObj[propertyName]; } "
    ScriptEngine.AddCode "function getKeys(jsonObj) { var keys = new Array(); for (var i in jsonObj) { keys.push(i); } return keys; } "
End Sub

Public Function DecodeJsonString(ByVal JsonString As String)
    Set DecodeJsonString = ScriptEngine.Eval("(" + JsonString + ")")
End Function

Public Function GetProperty(ByVal JsonObject As Object, ByVal propertyName As String) As Variant
    GetProperty = ScriptEngine.Run("getProperty", JsonObject, propertyName)
End Function

Public Function GetObjectProperty(ByVal JsonObject As Object, ByVal propertyName As String) As Object
    Set GetObjectProperty = ScriptEngine.Run("getProperty", JsonObject, propertyName)
End Function

Public Function GetKeys(ByVal JsonObject As Object) As String()
    Dim Length As Integer
    Dim KeysArray() As String
    Dim KeysObject As Object
    Dim Index As Integer
    Dim Key As Variant

    Set KeysObject = ScriptEngine.Run("getKeys", JsonObject)
    Length = GetProperty(KeysObject, "length")
    ReDim KeysArray(Length - 1)
    Index = 0
    For Each Key In KeysObject
        KeysArray(Index) = Key
        Index = Index + 1
    Next
    GetKeys = KeysArray
End Function


Public Sub TestJsonAccess()
    Dim JsonString As String
    Dim JsonObject As Object
    Dim Keys() As String
    Dim Value As Variant
    Dim j As Variant

    InitScriptEngine

    JsonString = "{""key1"": ""val1"", ""key2"": { ""key3"": ""val3"" } }"
    Set JsonObject = DecodeJsonString(CStr(JsonString))
    Keys = GetKeys(JsonObject)

    Value = GetProperty(JsonObject, "key1")
    Set Value = GetObjectProperty(JsonObject, "key2")
End Sub

A few notes:

• If the JScriptTypeInfo instance refers to a Javascript object, For Each ... Next won't work. However, it does work if it refers to a Javascript array (see GetKeys function).
• The access properties whose name is only known at run-time, use the functions GetProperty and GetObjectProperty.
• The Javascript array provides the properties length, 0, Item 0, 1, Item 1 etc. With the VBA dot notation (jsonObject.property), only the length property is accessible and only if you declare a variable called length with all lowercase letters. Otherwise the case doesn't match and it won't find it. The other properties are not valid in VBA. So better use the GetProperty function.
• The code uses early binding. So you have to add a reference to "Microsoft Script Control 1.0".
• You have to call InitScriptEngine once before using the other functions to do some basic initialization.

Sending raw POST requests can be sometimes more convenient. Below you can see post.js original example from PhantomJS

// Example using HTTP POST operation

var page = require('webpage').create(),
    server = 'http://posttestserver.com/post.php?dump',
    data = 'universe=expanding&answer=42';

page.open(server, 'post', data, function (status) {
    if (status !== 'success') {
        console.log('Unable to post!');
    } else {
        console.log(page.content);
    }
    phantom.exit();
});

Here is an example to find "all" occurrences of 10 along with the index. Thought this would be of some help.

void _find_all_test()
{
    vector<int> ints;
    int val;
    while(cin >> val) ints.push_back(val);

    vector<int>::iterator it;
    it = ints.begin();
    int count = ints.size();
    do
    {
        it = find(it,ints.end(), 10);//assuming 10 as search element
        cout << *it << " found at index " << count -(ints.end() - it) << endl;
    }while(++it != ints.end()); 
}

Config is written to .npmrc files so just delete it. NPM looks up config in this order, setting in the next overwrites the previous one. So make sure there might be global config that usually is overwritten in per-project that becomes active after you have deleted the per-project config file. npm config list will allways list the active config.

1. npm builtin config file (/path/to/npm/npmrc)
2. global config file ($PREFIX/etc/npmrc)
3. per-user config file ($HOME/.npmrc)
4. per-project config file (/path/to/my/project/.npmrc)

You can .write() the content into the iframe document. Example:

<iframe id="FileFrame" src="about:blank"></iframe>

<script type="text/javascript">
   var doc = document.getElementById('FileFrame').contentWindow.document;
   doc.open();
   doc.write('<html><head><title></title></head><body>Hello world.</body></html>');
   doc.close();
</script>

Not answering OPs question directly, but for the people finding this question in search of clarity on what's the difference between allow,deny and deny,allow:

Read the comma as a "but".

• allow but deny: whitelist with exceptions.
  everything is denied, except items on the allow list, except items on the deny list
• deny but allow: blacklist with exceptions.
  everything is allowed, except items on the deny list, except items on the allow list

allow only one country access, but exclude proxies within this country

OP needed a whitelist with exceptions, therefore allow,deny instead of deny,allow

You can run build for a specific service by running docker-compose up --build <service name> where the service name must match how did you call it in your docker-compose file.

Example Let's assume that your docker-compose file contains many services (.net app - database - let's encrypt... etc) and you want to update only the .net app which named as application in docker-compose file. You can then simply run docker-compose up --build application

Extra parameters In case you want to add extra parameters to your command such as -d for running in the background, the parameter must be before the service name: docker-compose up --build -d application

Yes, if bar is not None is more explicit, and thus better, assuming it is indeed what you want. That's not always the case, there are subtle differences: if not bar: will execute if bar is any kind of zero or empty container, or False. Many people do use not bar where they really do mean bar is not None.

Even I got the same issue and my mistake was that I didn't download python MSI file. You will get it here: https://www.python.org/downloads/

Once you download the msi, run the setup and that will solve the problem. After that you can go to File->Settings->Project Settings->Project Interpreter->Python Interpreters

and select the python.exe file. (This file will be available at c:\Python34) Select the python.exe file. That's it.

Take a look into jQuery's .load() function:

<script>
    $(function(){
        $('#siteloader').load('http://www.somesitehere.com');
    });
</script>

However, this only works on the same domain of the JS file.

Any of these will work from the shell command line. bc is probably your most straight forward solution though.

Using bc:

$ echo "$d1 - $d2" | bc

Using awk:

$ echo $d1 $d2 | awk '{print $1 - $2}'

Using perl:

$ perl -E "say $d1 - $d2"

Using Python:

$ python -c "print $d1 - $d2"

all return

No, functions are not first class objects in java. You can do the same thing by implementing a handler class - this is how callbacks are implemented in the Swing etc.

There are however proposals for closures (the official name for what you're talking about) in future versions of java - Javaworld has an interesting article.

Was facing this issue, Solved by adding package-info in my package

and the following code in it:

@XmlSchema(
    namespace = "http://www.w3schools.com/xml/",
    elementFormDefault = XmlNsForm.QUALIFIED,
    xmlns = {
        @XmlNs(prefix="", namespaceURI="http://www.w3schools.com/xml/")
    }
)  
package com.gateway.ws.outbound.bean;

import javax.xml.bind.annotation.XmlNs;
import javax.xml.bind.annotation.XmlNsForm;
import javax.xml.bind.annotation.XmlSchema;

Those errors :

"CMake Error: CMAKE_C_COMPILER not set, after EnableLanguage

CMake Error: CMAKE_CXX_COMPILER not set, after EnableLanguage"

means you haven't installed mingw32-base.

Go to http://sourceforge.net/projects/mingw/files/latest/download?source=files

and then make sure you select "mingw32-base"

Make sure you set up environment variables correctly in PATH section. "C:\MinGW\bin"

After that open CMake and Select Installation --> Delete Cache.

And click configure button again. I solved the problem this way, hope you solve the problem.

If two different views are sharing the same model (for instance, maybe one is for mobile output and one is regular), it could be nice to have the string reside in a single place: as metadata on the ViewModel.

Additionally, if you had an inherited version of the model that necessitated a different display, it could be useful. For instance:

public class BaseViewModel
{
    [Display(Name = "Basic Name")]
    public virtual string Name { get; set; }
}

public class OtherViewModel : BaseViewModel
{
    [Display(Name = "Customized Inherited Name")]
    public override string Name { get; set; }
}

I'll admit that that example is pretty contrived...

Those are the best arguments in favor of using the attribute that I can come up with. My personal opinion is that, for the most part, that sort of thing is best left to the markup.

Update: And here a nice article talking about it but using jQuery: Restricting Input in HTML Textboxes to Numeric Values

Try also the old syntax for casting,

SELECT ROUND(AVG(some_column)::numeric,2)    
FROM table;

works with any version of PostgreSQL.

There are a lack of overloads in some PostgreSQL functions, why (???): I think "it is a lack" (!), but @CraigRinger, @Catcall and the PostgreSQL team agree about "pg's historic rationale".

PS: another point about rounding is accuracy, check @IanKenney's answer.

Overloading as casting strategy

You can overload the ROUND function with,

 CREATE FUNCTION ROUND(float,int) RETURNS NUMERIC AS $$
    SELECT ROUND($1::numeric,$2);
 $$ language SQL IMMUTABLE;

Now your instruction will works fine, try (after function creation)

 SELECT round(1/3.,4); -- 0.3333 numeric

but it returns a NUMERIC type... To preserve the first commom-usage overload, we can return a FLOAT type when a TEXT parameter is offered,

 CREATE FUNCTION ROUND(float, text, int DEFAULT 0) 
 RETURNS FLOAT AS $$
    SELECT CASE WHEN $2='dec'
                THEN ROUND($1::numeric,$3)::float
                -- ... WHEN $2='hex' THEN ... WHEN $2='bin' THEN... complete!
                ELSE 'NaN'::float  -- like an error message 
            END;
 $$ language SQL IMMUTABLE;

Try

 SELECT round(1/3.,'dec',4);   -- 0.3333 float!
 SELECT round(2.8+1/3.,'dec',1); -- 3.1 float!
 SELECT round(2.8+1/3.,'dec'::text); -- need to cast string? pg bug 

PS: checking \df round after overloadings, will show something like,

 Schema     |  Name | Result data type | Argument data types 
------------+-------+------------------+----------------------------
 myschema   | round | double precision | double precision, text, int
 myschema   | round | numeric          | double precision, int
 pg_catalog | round | double precision | double precision            
 pg_catalog | round | numeric          | numeric   
 pg_catalog | round | numeric          | numeric, int          

The pg_catalog functions are the default ones, see manual of build-in math functions.

You can use COALESCE in conjunction with NULLIF for a short, efficient solution:

COALESCE( NULLIF(yourField,'') , '0' )

The NULLIF function will return null if yourField is equal to the second value ('' in the example), making the COALESCE function fully working on all cases:

                 QUERY                     |                RESULT 
---------------------------------------------------------------------------------
SELECT COALESCE(NULLIF(null  ,''),'0')     |                 '0'
SELECT COALESCE(NULLIF(''    ,''),'0')     |                 '0'
SELECT COALESCE(NULLIF('foo' ,''),'0')     |                 'foo'

I found that using cast() was the best solution for me:

cast(Format(amount, "Standard") AS CHAR CHARACTER SET utf8) AS Amount

There is also a convert() function. More details on it here

I can recommend add small extension to String or Array that looks like

extension Collection {
    public var isNotEmpty: Bool {
        return !self.isEmpty
    }
}

With it you can write code that is easier to read. Compare this two lines

if !someObject.someParam.someSubParam.someString.isEmpty {}

and

if someObject.someParam.someSubParam.someString.isNotEmpty {}

It is easy to miss ! sign in the beginning of fist line.

I think this is all you really need to do:

var listB = new List<int>{3, 4, 5};
var listA = new List<int>{1, 2, 3, 4, 5};

var listMerged = listA.Union(listB);

You just need to 'capture' the bit between the brackets.

\[(.*?)\]

To capture you put it inside parentheses. You do not say which language this is using. In Perl for example, you would access this using the $1 variable.

my $string ='This is the match [more or less]';
$string =~ /\[(.*?)\]/;
print "match:$1\n";

Other languages will have different mechanisms. C#, for example, uses the Match collection class, I believe.

We use

wsdlLocation = "WEB-INF/wsdl/WSDL.wsdl"

In other words, use a path relative to the classpath.

I believe the WSDL may be needed at runtime for validation of messages during marshal/unmarshal.

You can use either "=" or "==" operators for string comparison in bash. The important factor is the spacing within the brackets. The proper method is for brackets to contain spacing within, and operators to contain spacing around. In some instances different combinations work; however, the following is intended to be a universal example.

if [ "$1" == "something" ]; then     ## GOOD

if [ "$1" = "something" ]; then      ## GOOD

if [ "$1"="something" ]; then        ## BAD (operator spacing)

if ["$1" == "something"]; then       ## BAD (bracket spacing)

Also, note double brackets are handled slightly differently compared to single brackets ...

if [[ $a == z* ]]; then   # True if $a starts with a "z" (pattern matching).
if [[ $a == "z*" ]]; then # True if $a is equal to z* (literal matching).

if [ $a == z* ]; then     # File globbing and word splitting take place.
if [ "$a" == "z*" ]; then # True if $a is equal to z* (literal matching).

I hope that helps!

process.exit(1) should be used to exit with a failure code.This will allow us to infer that node didn't close gracefully and was forced to close.

There are other exit codes like

3 - Internal JavaScript Parse Error ( very very rare)

5 - Fatal error in v8 javascript engine

9 - Invalid argument

For full list see node exit codes

I usually copy the files in windows explorer, open them up in Notepad/Wordpad and just change the one mention of the class name at the top. Include those files in your project, and you'll be good to go.

Try the below code:

Sub opendfiles()

Dim myfile As Variant
Dim counter As Integer
Dim path As String

myfolder = "D:\temp\"
ChDir myfolder
myfile = Application.GetOpenFilename(, , , , True)
counter = 1
If IsNumeric(myfile) = True Then
    MsgBox "No files selected"
End If
While counter <= UBound(myfile)
    path = myfile(counter)
    Workbooks.Open path
    counter = counter + 1
Wend

End Sub

savez() save data in a zip file, It may take some time to zip & unzip the file. You can use save() & load() function:

f = file("tmp.bin","wb")
np.save(f,a)
np.save(f,b)
np.save(f,c)
f.close()

f = file("tmp.bin","rb")
aa = np.load(f)
bb = np.load(f)
cc = np.load(f)
f.close()

To save multiple arrays in one file, you just need to open the file first, and then save or load the arrays in sequence.

I prefer using pip in case you are using virtualenv:

1. apt install libpython2.7 libpython2.7-dev
2. pip install psycopg2

I use backgroundrb.

http://backgroundrb.rubyforge.org/

I use it to run scheduled tasks as well as tasks that take too long for the normal client/server relationship.

You need to process the image beforehand, to make a centered and stretched image. Try this:

UIGraphicsBeginImageContext(self.view.frame.size);
[[UIImage imageNamed:@"image.png"] drawInRect:self.view.bounds];
UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();

self.view.backgroundColor = [UIColor colorWithPatternImage:image];

Quick and easy with no external tools, works well as long as the two sheets you are comparing are similar:

• Create a third spreadsheet
• Type =if(Sheet1!A1 <> Sheet2!A1, "X", "") in the top left cell (or equivalent: click on the actual cells to automatically have the references inserted into the formula)
• Ctrl+C (copy), Ctrl+A (select all), Ctrl+V (paste) to fill the sheet.

If the sheets are similar, this spreadsheet will be empty except for a few cells with X in them, highlighting the differences. Unzoom to 40% to quickly see what is different.

public static String getDensity(Context context) {
    String r;
    DisplayMetrics metrics = new DisplayMetrics();

    if (!(context instanceof Activity)) {
        r = "hdpi";
    } else {
        Activity activity = (Activity) context;
        activity.getWindowManager().getDefaultDisplay().getMetrics(metrics);

        if (metrics.densityDpi <= DisplayMetrics.DENSITY_LOW) {
            r = "ldpi";
        } else if (metrics.densityDpi <= DisplayMetrics.DENSITY_MEDIUM) {
            r = "mdpi";
        } else {
            r = "hdpi";
        }
    }

    return r;
}

Update: There is now the possibility to use prefix to get the first n elements of an array. Check @mluisbrown's answer for an explanation how to use prefix.

Original Answer: You can do it really easy without filter, map or reduce by just returning a range of your array:

var wholeArray = [1, 2, 3, 4, 5, 6]
var n = 5

var firstFive = wholeArray[0..<n] // 1,2,3,4,5

window.location = myUrl;

Anyway, this is not jQuery: it's plain javascript

Disabling user-scalable (namely, the ability to double tap to zoom) allows the browser to reduce the click delay. In touch-enable browsers, when the user expects the double tap to zoom, the browser generally waits 300ms before firing the click event, waiting to see if the user will double tap. Disabling user-scalable allows for the Chrome browser to fire the click event immediately, allowing for a better user experience.

From Google IO 2013 session https://www.youtube.com/watch?feature=player_embedded&v=DujfpXOKUp8#t=1435s

Update: its not true anymore, <meta name="viewport" content="width=device-width"> is enough to remove 300ms delay

It should be at least this:

public function login(Request $loginCredentials){
     $data = $loginCredentials->all();
     return $data['username'];
}

If you want to have two tables next to each other you can use: (with float package loaded)

\begin{table}[H]
 \begin{minipage}{.5\textwidth}
  %first table
 \end{minipage}
 \begin{minipage}{.5\textwidth}
  %second table
 \end{minipage}
\end{table}

Each one will have own caption and number. Another option is subfigure package.

using PhpMyAdmin version 4.5.4.1deb2ubuntu2, you can set the variables in /etc/phpmyadmin/config-db.php

so set $dbserver to your server name, e.g. $dbserver='mysql.example.com';

<?php
##
## database access settings in php format
## automatically generated from /etc/dbconfig-common/phpmyadmin.conf
## by /usr/sbin/dbconfig-generate-include
##
## by default this file is managed via ucf, so you shouldn't have to
## worry about manual changes being silently discarded.  *however*,
## you'll probably also want to edit the configuration file mentioned
## above too.
##
$dbuser='phpmyadmin';
$dbpass='P@55w0rd';
$basepath='';
$dbname='phpmyadmin';
$dbserver='localhost';
$dbport='';
$dbtype='mysql';

Use,..

Color.parseColor("#bdbdbd");

like,

mTextView.setTextColor(Color.parseColor("#bdbdbd"));

Or if you have defined color code in resource's color.xml file than

(From API >= 23)

mTextView.setTextColor(ContextCompat.getColor(context, R.color.<name_of_color>));

(For API < 23)

mTextView.setTextColor(getResources().getColor(R.color.<name_of_color>));

I just solved this problem by unchecking Read only checkbox of the Program Files/eclipse folder on win7.

Apply to all files and folders.

You can use drop command to delete meta data and actual data from HDFS.

And just to delete data and keep the table structure, use truncate command.

We can simply declare more than one Controller in the same module. Here's an example:

  <!DOCTYPE html>
    <html>

      <h2> Books </h2>

    <!-- <input type="checkbox" ng-model="hideShow" ng-init="hideShow = false"></input> -->
    <input type = "button" value = "Add Book"ng-click="hideShow=(hideShow ? false : true)"> </input>

Sorry I didn't see your Java tag, was reading question only. I'll leave my other answers here anyway since I've typed them out.

Java

String myString = "9Hello World!";
if ( Character.isDigit(myString.charAt(0)) )
{
    System.out.println("String begins with a digit");
}

C++:

string myString = "2Hello World!";

if (isdigit( myString[0]) )
{
    printf("String begins with a digit");
}

Regular expression:

\b[0-9]

Some proof my regex works: Unless my test data is wrong?
