Use the latest supportLibrary, version 27.1.1 to solve the problem. worked for me. (many bug fixes included - see changelog)

I moved implementation to module-level build.gradle from root-level build.gradle. It solves the issue.

I had the same error, what solve my problem was. In my library instead of using compile or implementation i use "api". So in the end my dependencies:

dependencies {
api fileTree(dir: 'libs', include: ['*.jar'])
api files('libs/model.jar')
testApi 'junit:junit:4.12'
api 'com.android.support:percent:26.0.0-beta2'
api 'com.android.support:appcompat-v7:26.0.0-beta2'
api 'com.android.support:support-core-utils:26.0.0-beta2'

api 'com.squareup.retrofit2:retrofit:2.0.2'
api 'com.squareup.picasso:picasso:2.4.0'
api 'com.squareup.retrofit2:converter-gson:2.0.2'
api 'com.squareup.okhttp3:logging-interceptor:3.2.0'
api 'uk.co.chrisjenx:calligraphy:2.2.0'
api 'com.google.code.gson:gson:2.2.4'
api 'com.android.support:design:26.0.0-beta2'
api 'com.github.PhilJay:MPAndroidChart:v3.0.1'
}

You can find more info about "api", "implementation" in this link https://stackoverflow.com/a/44493379/3479489

I have updated old android project for the Wear OS. I have got this error message while build the project:

Manifest merger failed : Attribute meta-data#android.support.VERSION@value value=(26.0.2) from [com.android.support:percent:26.0.2] AndroidManifest.xml:25:13-35
is also present at [com.android.support:support-v4:26.1.0] AndroidManifest.xml:28:13-35 value=(26.1.0).
Suggestion: add 'tools:replace="android:value"' to <meta-data> element at AndroidManifest.xml:23:9-25:38 to override.

My build.gradle for Wear app contains these dependencies:

dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.google.android.support:wearable:2.4.0'
implementation 'com.google.android.gms:play-services-wearable:16.0.1'
compileOnly 'com.google.android.wearable:wearable:2.4.0'}

SOLUTION:

Adding implementation 'com.android.support:support-v4:28.0.0' into the dependencies solved my problem.

If the same error is on appcompat

implementation 'com.android.support:appcompat-v7:27.0.1'

then adding design solved it.

implementation 'com.android.support:appcompat-v7:27.0.1'
implementation 'com.android.support:design:27.0.1'

For me, adding

implementation 'de.mrmaffen:vlc-android-sdk:2.0.6'

was including appcompat-v7:23.1.1 in

.idea/libraries

without vlc, appcompat alone is enough.

For those having issues with the command line SDK, the reason it won't find the licenses you have accepted is because they have have been written to a different location than $ANDROID_HOME/licenses which is where they need to be.

I found the easiest solution was to accept the licenses like this:

$ANDROID_HOME/bin/sdkmanager --licenses --sdk_root=$ANDROID_HOME

Note: This assumes you've set ANDROID_HOME to point to wherever your sdk is installed.

For me, the problem was solved after I removed jar file from my project. it seems that one of the jar files inside my project was using an older version of google play services.

I had this problem when I delegated my compilation task to the Google Compute Engine via SSH. The nature of this issue is a memory error, as indicated by the crash log; specifically it is thrown when Java runs out of virtual memory to work with during the build.

Important: When gradle crashes due to this memory error, the gradle daemons remain running long after your compilation task has failed. Any re-attempt to build using gradle again will allocate a new gradle daemon. You must ensure that you properly dispose of any crashed instances using gradlew --stop.

The hs_error_pid crash logs indicates the following workarounds:

# There is insufficient memory for the Java Runtime Environment to continue.
# Possible reasons:
#   The system is out of physical RAM or swap space
#   In 32 bit mode, the process size limit was hit
# Possible solutions:
#   Reduce memory load on the system
#   Increase physical memory or swap space
#   Check if swap backing store is full
#   Use 64 bit Java on a 64 bit OS
#   Decrease Java heap size (-Xmx/-Xms)
#   Decrease number of Java threads
#   Decrease Java thread stack sizes (-Xss)
#   Set larger code cache with -XX:ReservedCodeCacheSize=

I found that after increasing the runtime resources of the virtual machine, this issue was resolved.

I was getting this error

Error:Execution failed for task ':app:preDebugAndroidTestBuild'. Conflict with dependency 'com.android.support:support-annotations' in project ':app'. Resolved versions for app (26.1.0) and test app (27.1.1) differ. See https://d.android.com/r/tools/test-apk-dependency-conflicts.html for details.

I was having following dependencies in my build.gradle file under Gradle Scripts

dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:26.1.0'
implementation 'com.android.support:support-v4:26.1.0'
implementation 'com.android.support:support-vector-drawable:26.1.0'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}

So, I resolved it by commenting the following dependencies

testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'

So my dependencies look like this

dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:26.1.0'
implementation 'com.android.support:support-v4:26.1.0'
implementation 'com.android.support:support-vector-drawable:26.1.0'
//testImplementation 'junit:junit:4.12'
//androidTestImplementation 'com.android.support.test:runner:1.0.2'
//androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}

Hope it helps!

If you are migrating to 1.0.0 you need to change the following properties.

In the Project's build.gradle file you need to replace minifyEnabled.

Hence your new build type should be

buildTypes {
    release {
        minifyEnabled true
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'        
    }
}

Also make sure that gradle version is 1.0.0 like

classpath 'com.android.tools.build:gradle:1.0.0'

in the build.gradle file.

This should solve the problem.

If none of the above makes sense:

tl;dr

Just like an implicitly unwrapped optional, If you can guarantee that the reference will not be nil at its point of use, use unowned. If not, then you should be using weak.

Explanation:

I retrieved the following below at: weak unowned link. From what I gathered, unowned self can't be nil but weak self can be, and unowned self can lead to dangling pointers...something infamous in Objective-C. Hope it helps

"UNOWNED Weak and unowned references behave similarly but are NOT the same."

Unowned references, like weak references, do not increase the retain count of the object being referred. However, in Swift, an unowned reference has the added benefit of not being an Optional. This makes them easier to manage rather than resorting to using optional binding. This is not unlike Implicitly Unwrapped Optionals . In addition, unowned references are non-zeroing. This means that when the object is deallocated, it does not zero out the pointer. This means that use of unowned references can, in some cases, lead to dangling pointers. For you nerds out there that remember the Objective-C days like I do, unowned references map to unsafe_unretained references.

This is where it gets a little confusing.

Weak and unowned references both do not increase retain counts.

They can both be used to break retain cycles. So when do we use them?!

According to Apple's docs:

“Use a weak reference whenever it is valid for that reference to become nil at some point during its lifetime. Conversely, use an unowned reference when you know that the reference will never be nil once it has been set during initialisation.”

You can define a Multi-module project structure, then you can set the configuration for sonar in one properties file in the root folder of your project, (Way #1)

With 0.7.0 there comes extended support for Lint, however, it does not work always properly. (Eg. the butterknife library)

Solution is to disable aborting build on found lint errors

I took the inspiration from https://android.googlesource.com/platform/tools/base/+/e6a5b9c7c1bca4da402de442315b5ff1ada819c7

(implementation: https://android.googlesource.com/platform/tools/base/+/e6a5b9c7c1bca4da402de442315b5ff1ada819c7/build-system/gradle/src/main/groovy/com/android/build/gradle/internal/model/DefaultAndroidProject.java )

(discussion: https://plus.google.com/+AndroidDevelopers/posts/ersS6fMLxw1 )

android {
  // your build config
  defaultConfig { ... }
  signingConfigs { ... }
  compileOptions { ... }
  buildTypes { ... }
  // This is important, it will run lint checks but won't abort build
  lintOptions {
      abortOnError false
  }
}

And if you need to disable just particular Lint rule and keep the build failing on others, use this:

/*
 * Use only 'disable' or only 'enable', those configurations exclude each other
 */
android {
  lintOptions {
    // use this line to check all rules except those listed
    disable 'RuleToDisable', 'SecondRuleToDisable'
    // use this line to check just listed rules
    enable 'FirstRuleToCheck', 'LastRuleToCheck'
  }
}

Try this Query

select NUM, count(1) as count 
from tbl 
where num = 1
group by NUM
--having count(1) (You condition)

SQL FIDDLE

When your script is running, it blocks the page from doing anything. You can work around this with one of two ways:

• Use var foo = prompt("Give me input");, which will give you the string that the user enters into a popup box (or null if they cancel it)
• Split your code into two function - run one function to set up the user interface, then provide the second function as a callback that gets run when the user clicks the button.

Hi if your are looking for simple android image sliding with circle indicator you can download the complete code from here http://javaant.com/viewpager-with-circle-indicator-in-android/#.VysQQRV96Hs . please check the live demo which will give the clear idea.

Oracle does automatic String2number conversion, for String column values! However, for the textual comparisons in SQL, the input must be delimited as a String explicitly: The opposite conversion number2String is not performed automatically, not on the SQL-query level.

I had this query:

select max(acc_num) from ACCOUNTS where acc_num between 1001000 and 1001999;

That one presented a problem: Error: ORA-01722: invalid number

I have just surrounded the "numerical" values, to make them 'Strings', just making them explicitly delimited:

select max(acc_num) from ACCOUNTS where acc_num between '1001000' and '1001999';

...and voilà: It returns the expected result.

edit: And indeed: the col acc_num in my table is defined as String. Although not numerical, the invalid number was reported. And the explicit delimiting of the string-numbers resolved the problem.

On the other hand, Oracle can treat Strings as numbers. So the numerical operations/functions can be applied on the Strings, and these queries work:

select max(string_column) from TABLE;

select string_column from TABLE where string_column between '2' and 'z';

select string_column from TABLE where string_column > '1';

select string_column from TABLE where string_column <= 'b';

Here is one way to do this, using UNION ALL (See SQL Fiddle with Demo). This works with two groups, if you have more than two groups, then you would need to specify the group number and add queries for each group:

(
  select *
  from mytable 
  where `group` = 1
  order by age desc
  LIMIT 2
)
UNION ALL
(
  select *
  from mytable 
  where `group` = 2
  order by age desc
  LIMIT 2
)

There are a variety of ways to do this, see this article to determine the best route for your situation:

http://www.xaprb.com/blog/2006/12/07/how-to-select-the-firstleastmax-row-per-group-in-sql/

Edit:

This might work for you too, it generates a row number for each record. Using an example from the link above this will return only those records with a row number of less than or equal to 2:

select person, `group`, age
from 
(
   select person, `group`, age,
      (@num:=if(@group = `group`, @num +1, if(@group := `group`, 1, 1))) row_number 
  from test t
  CROSS JOIN (select @num:=0, @group:=null) c
  order by `Group`, Age desc, person
) as x 
where x.row_number <= 2;

See Demo

My solution works only if you need retrieve only one column, however for my needs was the best solution found in terms of performance (it use only one single query!):

SELECT SUBSTRING_INDEX(GROUP_CONCAT(column_x ORDER BY column_y),',',1) AS xyz,
   column_z
FROM table_name
GROUP BY column_z;

It use GROUP_CONCAT in order to create an ordered concat list and then I substring to only the first one.

Symbolic or soft link (files or directories, more flexible and self documenting)

#     Source                             Link
ln -s /home/jake/doc/test/2000/something /home/jake/xxx

Hard link (files only, less flexible and not self documenting)

#   Source                             Link
ln /home/jake/doc/test/2000/something /home/jake/xxx

More information: man ln

/home/jake/xxx is like a new directory. To avoid "is not a directory: No such file or directory" error, as @trlkly comment, use relative path in the target, that is, using the example:

1. cd /home/jake/
2. ln -s /home/jake/doc/test/2000/something xxx

Uploading files is actually possible with AJAX these days. Yes, AJAX, not some crappy AJAX wannabes like swf or java.

This example might help you out: https://webblocks.nl/tests/ajax/file-drag-drop.html

(It also includes the drag/drop interface but that's easily ignored.)

Basically what it comes down to is this:

<input id="files" type="file" />

<script>
document.getElementById('files').addEventListener('change', function(e) {
    var file = this.files[0];
    var xhr = new XMLHttpRequest();
    (xhr.upload || xhr).addEventListener('progress', function(e) {
        var done = e.position || e.loaded
        var total = e.totalSize || e.total;
        console.log('xhr progress: ' + Math.round(done/total*100) + '%');
    });
    xhr.addEventListener('load', function(e) {
        console.log('xhr upload complete', e, this.responseText);
    });
    xhr.open('post', '/URL-HERE', true);
    xhr.send(file);
});
</script>

(demo: http://jsfiddle.net/rudiedirkx/jzxmro8r/)

So basically what it comes down to is this =)

xhr.send(file);

Where file is typeof Blob: http://www.w3.org/TR/FileAPI/

Another (better IMO) way is to use FormData. This allows you to 1) name a file, like in a form and 2) send other stuff (files too), like in a form.

var fd = new FormData;
fd.append('photo1', file);
fd.append('photo2', file2);
fd.append('other_data', 'foo bar');
xhr.send(fd);

FormData makes the server code cleaner and more backward compatible (since the request now has the exact same format as normal forms).

All of it is not experimental, but very modern. Chrome 8+ and Firefox 4+ know what to do, but I don't know about any others.

This is how I handled the request (1 image per request) in PHP:

if ( isset($_FILES['file']) ) {
    $filename = basename($_FILES['file']['name']);
    $error = true;

    // Only upload if on my home win dev machine
    if ( isset($_SERVER['WINDIR']) ) {
        $path = 'uploads/'.$filename;
        $error = !move_uploaded_file($_FILES['file']['tmp_name'], $path);
    }

    $rsp = array(
        'error' => $error, // Used in JS
        'filename' => $filename,
        'filepath' => '/tests/uploads/' . $filename, // Web accessible
    );
    echo json_encode($rsp);
    exit;
}

As others mentioned, you can do this with ConfigurationManager.AppSettings.Settings. But: Using Settings[key] = value will not work if the key doesn't exist.
Using Settings.Add(key, value), if the key already exists, it will join the new value to its value(s) separated by a comma, something like <add key="myKey" value="value1, value2, value3" />

To avoid these unexpected results, you have to handle two scenario's

• If entry with the given key exists? then update its value
• if entry with the given key doesn't exist? then create new entry(key,value)

Code

public static void Set(string key, string value)
{
    var config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);

    var entry = config.AppSettings.Settings[key];
    if (entry == null)
        config.AppSettings.Settings.Add(key, value);
    else
        config.AppSettings.Settings[key].Value = value;

    config.Save(ConfigurationSaveMode.Modified);
}

For more info about the check entry == null, check this post.
Hope this will help someone.

You can use method getDate():

$('#calendar').datepicker({
    dateFormat: 'yy-m-d',
    inline: true,
    onSelect: function(dateText, inst) { 
        var date = $(this).datepicker('getDate'),
            day  = date.getDate(),  
            month = date.getMonth() + 1,              
            year =  date.getFullYear();
        alert(day + '-' + month + '-' + year);
    }
});

FIDDLE

Jin Yong - IE has an issue with polluting the global scope with object references to any DOM elements with a "name" or "id" attribute set on the "initial" page load.

Thus you may have issues due to your variable name.

Try this and see if it works.

var someOtherName="abc";
//  ^^^^^^^^^^^^^
document.getElementById('msg').value = someOtherName;
document.getElementById('sp_100').checked = true;

There is a chance (in your original code) that IE attempts to set the value of the input to a reference to that actual element (ignores the error) but leaves you with no new value.

Keep in mind that in IE6/IE7 case doesn't matter for naming objects. IE believes that "foo" "Foo" and "FOO" are all the same object.

I just wanted to share something with you.
I got some hard time with ng-mouseenter and ng-mouseleave events.

The case study:

I created a floating navigation menu which is toggle when the cursor is over an icon.
This menu was on top of each page.

• To handle show/hide on the menu, I toggle a class.
  ng-class="{down: vm.isHover}"
• To toggle vm.isHover, I use the ng mouse events.
  ng-mouseenter="vm.isHover = true"
ng-mouseleave="vm.isHover = false"

For now, everything was fine and worked as expected.
The solution is clean and simple.

The incoming problem:

In a specific view, I have a list of elements.
I added an action panel when the cursor is over an element of the list.
I used the same code as above to handle the behavior.

The problem:

I figured out when my cursor is on the floating navigation menu and also on the top of an element, there is a conflict between each other.
The action panel showed up and the floating navigation was hide.

The thing is that even if the cursor is over the floating navigation menu, the list element ng-mouseenter is triggered.
It makes no sense to me, because I would expect an automatic break of the mouse propagation events.
I must say that I was disappointed and I spend some time to find out that problem.

First thoughts:

I tried to use these :

• $event.stopPropagation()
• $event.stopImmediatePropagation()

I combined a lot of ng pointer events (mousemove, mouveover, ...) but none help me.

CSS solution:

I found the solution with a simple css property that I use more and more:

pointer-events: none;

Basically, I use it like that (on my list elements):

ng-style="{'pointer-events': vm.isHover ? 'none' : ''}"

With this tricky one, the ng-mouse events will no longer be triggered and my floating navigation menu will no longer close himself when the cursor is over it and over an element from the list.

To go further:

As you may expect, this solution works but I don't like it.
We do not control our events and it is bad.
Plus, you must have an access to the vm.isHover scope to achieve that and it may not be possible or possible but dirty in some way or another.
I could make a fiddle if someone want to look.

Nevertheless, I don't have another solution...
It's a long story and I can't give you a potato so please forgive me my friend.
Anyway, pointer-events: none is life, so remember it.

If you think your volume is a "network drive", it will be easier. To edit the file located in this drive, you just need to turn on another machine and connect to this network drive, then edit the file like normal.

How to do that purely with docker (without FTP/SSH ...)?

1. Run a container that has an editor (VI, Emacs). Search Docker hub for "alpine vim"

Example:

docker run -d --name shared_vim_editor \
 -v <your_volume>:/home/developer/workspace \
jare/vim-bundle:latest

2. Run the interactive command:

docker exec -it -u root shared_vim_editor /bin/bash

Hope this helps.

Assuming you can put ID's on the inputs:

$('#name').change(function() {
    $('#firstname').val($(this).val());
});

JSFiddle Example

Otherwise you'll have to select using the names:

$('input[name="name"]').change(function() {
    $('input[name="firstname"]').val($(this).val());
});

Try margin-top:

<header style="margin-top: -20px;">
    ...

Edit:

Now I found relative position probably a better choice:

<header style="position: relative; top: -20px;">
    ...

If you want to reset every RowId via content provider try this

rowCounter=1;
do {            
            rowId = cursor.getInt(0);
            ContentValues values;
            values = new ContentValues();
            values.put(Table_Health.COLUMN_ID,
                       rowCounter);
            updateData2DB(context, values, rowId);
            rowCounter++;

        while (cursor.moveToNext());

public static void updateData2DB(Context context, ContentValues values, int rowId) {
    Uri uri;
    uri = Uri.parseContentProvider.CONTENT_URI_HEALTH + "/" + rowId);
    context.getContentResolver().update(uri, values, null, null);
}

Excel automatically does this whenever you have a vertical column of items. If you select the blank cell below (or above) the column and start typing, it does autocomplete based on everything in the column.

The answer depends on your server's week-start set up, so it's either

SELECT [date_created] FROM table WHERE DATEPART(w,[date_created]) NOT IN (7,1)

if Sunday is the first day of the week for your server

or

SELECT [date_created] FROM table WHERE DATEPART(w,[date_created]) NOT IN (6,7)

if Monday is the first day of the week for your server

Comment if you've got any questions :-)

Use Curses or ANSI escape sequences. Before you start spouting escape sequences, you should check that stdout is a tty. You can do this with sys.stdout.isatty(). Here's a function pulled from a project of mine that prints output in red or green, depending on the status, using ANSI escape sequences:

def hilite(string, status, bold):
    attr = []
    if status:
        # green

The only way to determine this is to try it. FWIW I have seen some really good improvements using Apple's LLVM gcc 4.2 compared to the regular gcc 4.2 (for x86-64 code with quite a lot of SSE), but YMMV for different code bases. Assuming you're working with x86/x86-64 and that you really do care about the last few percent then you ought to try Intel's ICC too, as this can often beat gcc - you can get a 30 day evaluation license from intel.com and try it.

Try this:

UPDATE barang
SET ID FROM(SELECT tblkatalog.tblkatalog_id FROM tblkatalog 
WHERE tblkatalog.tblkatalog_nomor = barang.NO_CAT) WHERE barang.NO_CAT <>'';

Adding remote repo (as "foo") from which we want to cherry-pick

$ git remote add foo git://github.com/foo/bar.git

Fetch their branches

$ git fetch foo

List their commits (this should list all commits in the fetched foo)

$ git log foo/master

Cherry-pick the commit you need

$ git cherry-pick 97fedac

You could use Underscore.js, which is a Javascript utility library.

_.keys({one : 1, two : 2, three : 3}); 
// => ["one", "two", "three"]

This is plain Javascript and has nothing to do with the jQuery library.

You simply escape the apostrophe with a backslash:

theAnchorText = 'I\'m home';

Another alternative is to use quotation marks around the string, then you don't have to escape apostrophes:

theAnchorText = "I'm home";

XmlTextWriter xw = new XmlTextWriter(writer);
xw.Formatting = Formatting.Indented;

There have been many answers here and just about all of them will get the job done.

However there is some misleading advice!

Here are the options:

vector<int> dataVec;

int dataArray[] = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 };
unsigned dataArraySize = sizeof(dataArray) / sizeof(int);

// Method 1: Copy the array to the vector using back_inserter.
{
    copy(&dataArray[0], &dataArray[dataArraySize], back_inserter(dataVec));
}

// Method 2: Same as 1 but pre-extend the vector by the size of the array using reserve
{
    dataVec.reserve(dataVec.size() + dataArraySize);
    copy(&dataArray[0], &dataArray[dataArraySize], back_inserter(dataVec));
}

// Method 3: Memcpy
{
    dataVec.resize(dataVec.size() + dataArraySize);
    memcpy(&dataVec[dataVec.size() - dataArraySize], &dataArray[0], dataArraySize * sizeof(int));
}

// Method 4: vector::insert
{
    dataVec.insert(dataVec.end(), &dataArray[0], &dataArray[dataArraySize]);
}

// Method 5: vector + vector
{
    vector<int> dataVec2(&dataArray[0], &dataArray[dataArraySize]);
    dataVec.insert(dataVec.end(), dataVec2.begin(), dataVec2.end());
}

To cut a long story short Method 4, using vector::insert, is the best for bsruth's scenario.

Here are some gory details:

Method 1 is probably the easiest to understand. Just copy each element from the array and push it into the back of the vector. Alas, it's slow. Because there's a loop (implied with the copy function), each element must be treated individually; no performance improvements can be made based on the fact that we know the array and vectors are contiguous blocks.

Method 2 is a suggested performance improvement to Method 1; just pre-reserve the size of the array before adding it. For large arrays this might help. However the best advice here is never to use reserve unless profiling suggests you may be able to get an improvement (or you need to ensure your iterators are not going to be invalidated). Bjarne agrees. Incidentally, I found that this method performed the slowest most of the time though I'm struggling to comprehensively explain why it was regularly significantly slower than method 1...

Method 3 is the old school solution - throw some C at the problem! Works fine and fast for POD types. In this case resize is required to be called since memcpy works outside the bounds of vector and there is no way to tell a vector that its size has changed. Apart from being an ugly solution (byte copying!) remember that this can only be used for POD types. I would never use this solution.

Method 4 is the best way to go. It's meaning is clear, it's (usually) the fastest and it works for any objects. There is no downside to using this method for this application.

Method 5 is a tweak on Method 4 - copy the array into a vector and then append it. Good option - generally fast-ish and clear.

Finally, you are aware that you can use vectors in place of arrays, right? Even when a function expects c-style arrays you can use vectors:

vector<char> v(50); // Ensure there's enough space
strcpy(&v[0], "prefer vectors to c arrays");

Hope that helps someone out there!

For me, I wanted a string representation unless it was null, in which case I wanted it to remain null.

The problem with var_export is it converts null to a string "NULL" and it also converts an empty string to "''", which is undesirable. There was no easy solution that I could find.

This was the code I finally used:

if (is_bool($val)) $val ? $val = "true" : $val = "false";
else if ($val !== null) $val = (string)$val;

Short and simple and easy to throw in a function too if you prefer.

You cannot do it with just method, unless you use some javascript framework like jquery which supports it ..

string s = '<div id="myDiv"></div>'
var htmlObject = $(s); // jquery call

but still, it would not be found by the getElementById because for that to work the element must be in the DOM... just creating in the memory does not insert it in the dom.

You would need to use append or appendTo or after etc.. to put it in the dom first..

Of'course all these can be done through regular javascript but it would take more steps to accomplish the same thing... and the logic is the same in both cases..

You can use os.scandir(). New function in stdlib starts from Python 3.5.

import os

for entry in os.scandir('.'):
    if entry.is_file():
        print(entry.name)

Faster than os.listdir(). os.walk() implements os.scandir().

The script tag to the api has changed recently. Use something like this to query the Geocoding API and get the JSON object back

<script type="text/javascript" src="https://maps.googleapis.com/maps/api/geocode/json?address=THE_ADDRESS_YOU_WANT_TO_GEOCODE&key=YOUR_API_KEY"></script>

The address could be something like

1600+Amphitheatre+Parkway,+Mountain+View,+CA (URI Encoded; you should Google it. Very useful)

or simply

1600 Amphitheatre Parkway, Mountain View, CA

By entering this address https://maps.googleapis.com/maps/api/geocode/json?address=1600+Amphitheatre+Parkway,+Mountain+View,+CA&key=YOUR_API_KEY inside the browser, along with my API Key, I get back a JSON object which contains the Latitude & Longitude for the city of Moutain view, CA.

Web Frameworks such like AngularJS allow us to perform these queries with ease.

If you hadn't made any commit yet, only (1: branch) and (3: checkout) would be enough.
Or, in one command: git checkout -b newBranch

As mentioned in the git reset man page:

$ git branch topic/wip     # (1)
$ git reset --hard HEAD~3  # (2)  NOTE: use $git reset --soft HEAD~3 (explanation below)
$ git checkout topic/wip   # (3)

1. You have made some commits, but realize they were premature to be in the "master" branch. You want to continue polishing them in a topic branch, so create "topic/wip" branch off of the current HEAD.
2. Rewind the master branch to get rid of those three commits.
3. Switch to "topic/wip" branch and keep working.

Note: due to the "destructive" effect of a git reset --hard command (it does resets the index and working tree. Any changes to tracked files in the working tree since <commit> are discarded), I would rather go with:

$ git reset --soft HEAD~3  # (2)

This would make sure I'm not losing any private file (not added to the index).
The --soft option won't touch the index file nor the working tree at all (but resets the head to <commit>, just like all modes do).

With Git 2.23+, the new command git switch would create the branch in one line (with the same kind of reset --hard, so beware of its effect):

git switch -f -c topic/wip HEAD~3

I was getting the same error and nothing was wrong with my java files and packages. Later I noticed that the folder name WEB-INF was written like this "WEB_INF". So correcting just the folder name solved the issue

function getCaretPosition() {
    var x = 0;
    var y = 0;
    var sel = window.getSelection();
    if(sel.rangeCount) {
        var range = sel.getRangeAt(0).cloneRange();
        if(range.getClientRects()) {
        range.collapse(true);
        var rect = range.getClientRects()[0];
        if(rect) {
            y = rect.top;
            x = rect.left;
        }
        }
    }
    return {
        x: x,
        y: y
    };
}

This cannot be done with the native javascript dialog box, but a lot of javascript libraries include more flexible dialogs. You can use something like jQuery UI's dialog box for this.

See also these very similar questions:

• JavaScript confirm box with custom buttons
• custom choices in javascript confirm dialog

Here's an example, as demonstrated in this jsFiddle:

    <script type="text/javascript">

        $(function() {
            $('.checked').click(function(e) {
                e.preventDefault();
                var dialog = $('<p>Are you sure?</p>').dialog({
                    buttons: {
                        "Yes": function() {alert('you chose yes');},
                        "No":  function() {alert('you chose no');},
                        "Cancel":  function() {
                            alert('you chose cancel');
                            dialog.dialog('close');
                        }
                    }
                });
            });
        });

For Oracle, it is also LENGTH instead of LEN

SELECT MAX(LENGTH(Desc)) FROM table_name

Also, DESC is a reserved word. Although many reserved words will still work for column names in many circumstances it is bad practice to do so, and can cause issues in some circumstances. They are reserved for a reason.

If the word Desc was just being used as an example, it should be noted that not everyone will realize that, but many will realize that it is a reserved word for Descending. Personally, I started off by using this, and then trying to figure out where the column name went because all I had were reserved words. It didn't take long to figure it out, but keep that in mind when deciding on what to substitute for your actual column name.

The make uses the $ for its own variable expansions. E.g. single character variable $A or variable with a long name - ${VAR} and $(VAR).

To put the $ into a command, use the $$, for example:

all:
  @echo "Please execute next commands:"
  @echo 'setenv PATH /usr/local/greenhills/mips5/linux86:$$PATH'

Also note that to make the "" and '' (double and single quoting) do not play any role and they are passed verbatim to the shell. (Remove the @ sign to see what make sends to shell.) To prevent the shell from expanding $PATH, second line uses the ''.

The answer by @akrun certainly does the trick. For future googlers who want to understand why, here is an explanation...

The new variable needs to be created first.

The variable "valueBin" needs to be already in the df in order for the conditional assignment to work. Essentially, the syntax of the code is correct. Just add one line in front of the code chuck to create this name --

df$newVariableName <- NA

Then you continue with whatever conditional assignment rules you have, like

df$newVariableName[which(df$oldVariableName<=250)] <- "<=250"

I blame whoever wrote that package's error message... The debugging was made especially confusing by that error message. It is irrelevant information that you have two arrays in the df with different lengths. No. Simply create the new column first. For more details, consult this post https://www.r-bloggers.com/translating-weird-r-errors/

If you prefer binding your events outside the html-markup (in the javascript) you could do it like this:

document.getElementById("curtainInput").addEventListener(_x000D_
  "click",_x000D_
  function(event) {_x000D_
    if (event.target.value === "Open Curtain") {_x000D_
      event.target.value = "Close Curtain";_x000D_
    } else {_x000D_
      event.target.value = "Open Curtain";_x000D_
    }_x000D_
  },_x000D_
  false_x000D_
);

<!doctype html>_x000D_
<html>_x000D_
<body>_x000D_
  <input _x000D_
         id="curtainInput" _x000D_
         type="button" _x000D_
         value="Open Curtain" />_x000D_

Here's what I use:

<logger name="org.hibernate">

Obviously, I don't like to see Hibernate messages ;) -- set the level to "debug" to get the output.

I don't think that anybody has mentioned this, but alloca also has some serious security issues not necessarily present with malloc (though these issues also arise with any stack based arrays, dynamic or not). Since the memory is allocated on the stack, buffer overflows/underflows have much more serious consequences than with just malloc.

In particular, the return address for a function is stored on the stack. If this value gets corrupted, your code could be made to go to any executable region of memory. Compilers go to great lengths to make this difficult (in particular by randomizing address layout). However, this is clearly worse than just a stack overflow since the best case is a SEGFAULT if the return value is corrupted, but it could also start executing a random piece of memory or in the worst case some region of memory which compromises your program's security.

It is a textual file that includes a description of the library.

It allows libtool to create platform-independent names.

For example, libfoo goes to:

Under Linux:

/lib/libfoo.so       # Symlink to shared object
/lib/libfoo.so.1     # Symlink to shared object
/lib/libfoo.so.1.0.1 # Shared object
/lib/libfoo.a        # Static library
/lib/libfoo.la       # 'libtool' library

Under Cygwin:

/lib/libfoo.dll.a    # Import library
/lib/libfoo.a        # Static library
/lib/libfoo.la       # libtool library
/bin/cygfoo_1.dll    # DLL

Under Windows MinGW:

/lib/libfoo.dll.a    # Import library
/lib/libfoo.a        # Static library
/lib/libfoo.la       # 'libtool' library
/bin/foo_1.dll       # DLL

So libfoo.la is the only file that is preserved between platforms by libtool allowing to understand what happens with:

• Library dependencies
• Actual file names
• Library version and revision

Without depending on a specific platform implementation of libraries.

or you can use package doBy

library(doBy)
dd <- orderBy(~-z+b, data=dd)

If its just diagrams that you want, doxygen does a pretty good job.

Above Solutions will only convert dictionary into string but you can't convert back that string to dictionary. For that it is the better way.

Convert to String

NSError * err;
NSData * jsonData = [NSJSONSerialization  dataWithJSONObject:yourDictionary options:0 error:&err];
NSString * myString = [[NSString alloc] initWithData:jsonData   encoding:NSUTF8StringEncoding];
NSLog(@"%@",myString);

Convert Back to Dictionary

NSError * err;
NSData *data =[myString dataUsingEncoding:NSUTF8StringEncoding];
NSDictionary * response;
if(data!=nil){
 response = (NSDictionary *)[NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:&err];
}

I checked the answer however, (for each) in PHP is deprecated and no longer work with the latest php versions.

Usually we would convert an array into a string to log it somewhere, perhaps debugging or test etc.

I would convert the array into a string by doing:

$Output = implode(",", $SourceArray);

Whereas:

$output is the result (where the string would be generated

",": is the separator (between each array field

$SourceArray: is your source array.

I hope this helps

Be very careful when using find and sed in a git repo! If you don't exclude the binary files you can end up with this error:

error: bad index file sha1 signature 
fatal: index file corrupt

To solve this error you need to revert the sed by replacing your new_string with your old_string. This will revert your replaced strings, so you will be back to the beginning of the problem.

The correct way to search for a string and replace it is to skip find and use grep instead in order to ignore the binary files:

sed -ri -e "s/old_string/new_string/g" $(grep -Elr --binary-files=without-match "old_string" "/files_dir")

I thought I answer this question even though the answer is partly mentioned in both Adam Schmideg's and Alex Martelli's answers. In order for others like me that have the same question, to find the answer easily.

conn = sqlite3.connect(":memory:")

#This is the important part, here we are setting row_factory property of
#connection object to sqlite3.Row(sqlite3.Row is an implementation of
#row_factory)
conn.row_factory = sqlite3.Row
c = conn.cursor()
c.execute('select * from stocks')

result = c.fetchall()
#returns a list of dictionaries, each item in list(each dictionary)
#represents a row of the table

You should be using @RequestParam instead of @ModelAttribute, e.g.

@RequestMapping("/{someID}")
public @ResponseBody int getAttr(@PathVariable(value="someID") String id, 
                                 @RequestParam String someAttr) {
}

You can even omit @RequestParam altogether if you choose, and Spring will assume that's what it is:

@RequestMapping("/{someID}")
public @ResponseBody int getAttr(@PathVariable(value="someID") String id, 
                                 String someAttr) {
}

You have to clear the cache like that (because your old configuration is in you cache file) :

php artisan cache:clear

The pdo error comes from the fact Laravel use the pdo driver to connect to mysql

Do you mean you want to tell your copy of IE 10 to render the pages it views in IE 9 mode?

Or do you mean you want your website to force IE 10 to render it in IE 9 mode?

For the former:

To force a webpage you are viewing in Internet Explorer 10 into a particular document compatibility mode, first open F12 Tools by pressing the F12 key. Then, on the Browser Mode menu, click Internet Explorer 10, and on the Document Mode menu, click Standards.

http://msdn.microsoft.com/en-gb/library/ie/hh920756(v=vs.85).aspx

For the latter, the other answers are correct, but I wouldn't advise doing that. IE 10 is more standards-compliant (i.e. more similar to other browsers) than IE 9.

Now on Zend2:

$select->getSqlString();

Displaying the generated SQL from ZendDbSql object

http://htmldog.com/articles/superscript/ Essentially:

position: relative;
bottom: 0.5em;
font-size: 0.8em;

Works well in practice, as far as I can tell.

Arrays are values... slices are more like pointers. That is [n]type is not compatible with []type as they are fundamentally two different things. You can get a slice that points to an array by using arr[:] which returns a slice that has arr as it's backing storage.

One way to convert a slice of for example []byte to [20]byte is to actually allocate a [20]byte which you can do by using var [20]byte (as it's a value... no make needed) and then copy data into it:

buf := make([]byte, 10)
var arr [10]byte
copy(arr[:], buf)

Essentially what a lot of other answers get wrong is that []type is NOT an array.

[n]T and []T are completely different things!

When using reflect []T is not of kind Array but of kind Slice and [n]T is of kind Array.

You also can't use map[[]byte]T but you can use map[[n]byte]T.

This can sometimes be cumbersome because a lot of functions operate for example on []byte whereas some functions return [n]byte (most notably the hash functions in crypto/*). A sha256 hash for example is [32]byte and not []byte so when beginners try to write it to a file for example:

sum := sha256.Sum256(data)
w.Write(sum)

they will get an error. The correct way of is to use

w.Write(sum[:])

However, what is it that you want? Just accessing the string bytewise? You can easily convert a string to []byte using:

bytes := []byte(str)

but this isn't an array, it's a slice. Also, byte != rune. In case you want to operate on "characters" you need to use rune... not byte.

If you want to unstage all the changes use below command,

git reset --soft HEAD

In the case you want to unstage changes and revert them from the working directory,

git reset --hard HEAD

Because in either case the increment is done after the body of the loop and thus doesn't affect any of the calculations of the loop. If the compiler is stupid, it might be slightly less efficient to use post-increment (because normally it needs to keep a copy of the pre value for later use), but I would expect any differences to be optimized away in this case.

It might be handy to think of how the for loop is implemented, essentially translated into a set of assignments, tests, and branch instructions. In pseudo-code the pre-increment would look like:

      set i = 0
test: if i >= 5 goto done
      call printf,"%d",i
      set i = i + 1
      goto test
done: nop

Post-increment would have at least another step, but it would be trivial to optimize away

      set i = 0
test: if i >= 5 goto done
      call printf,"%d",i
      set j = i   // store value of i for later increment
      set i = j + 1  // oops, we're incrementing right-away
      goto test
done: nop

To revert the revert without screwing up your workflow too much:

• Create a local trash copy of develop
• Revert the revert commit on the local copy of develop
• Merge that copy into your feature branch, and push your feature branch to your git server.

Your feature branch should now be able to be merged as normal when you're ready for it. The only downside here is that you'll a have a few extra merge/revert commits in your history.

If you don't mind a dependency and want to use promises, child-process-promise works:

installation

npm install child-process-promise --save

exec Usage

var exec = require('child-process-promise').exec;

exec('echo hello')
    .then(function (result) {
        var stdout = result.stdout;
        var stderr = result.stderr;
        console.log('stdout: ', stdout);
        console.log('stderr: ', stderr);
    })
    .catch(function (err) {
        console.error('ERROR: ', err);
    });

spawn usage

var spawn = require('child-process-promise').spawn;

var promise = spawn('echo', ['hello']);

var childProcess = promise.childProcess;

console.log('[spawn] childProcess.pid: ', childProcess.pid);
childProcess.stdout.on('data', function (data) {
    console.log('[spawn] stdout: ', data.toString());
});
childProcess.stderr.on('data', function (data) {
    console.log('[spawn] stderr: ', data.toString());
});

promise.then(function () {
        console.log('[spawn] done!');
    })
    .catch(function (err) {
        console.error('[spawn] ERROR: ', err);
    });

If you want to control the formatting of the unique identifier you can create your own <FieldType> in SharePoint. MSDN also has a visual How-To. This basically means that you're creating a custom column.

WSS defines the Counter field type (which is what the ID column above is using). I've never had the need to re-use this or extend it, but it should be possible.

A solution might exist without creating a custom <FieldType>. For example: if you wanted unique IDs like CUST1, CUST2, ... it might be possible to create a Calculated column and use the value of the ID column in you formula (="CUST" & [ID]). I haven't tried this, but this should work :)

You can invoke methods of a class instance using reflection, doing a dynamic method invocation:

Suppose that you have a method called hello in a the actual instance (this):

string methodName = "hello";

//Get the method information using the method info class
 MethodInfo mi = this.GetType().GetMethod(methodName);

//Invoke the method
// (null- no parameter for the method call
// or you can pass the array of parameters...)
mi.Invoke(this, null);

I was asking the same too. Another solution is you could overload your method:

void remove_id(EmployeeClass);
void remove_id(ProductClass);
void remove_id(DepartmentClass);

in the call the argument will fit accordingly the object you pass. but then you will have to repeat yourself

void remove_id(EmployeeClass _obj) {
    int saveId = _obj->id;
    ...
};

void remove_id(ProductClass _obj) {
    int saveId = _obj->id;
    ...
};

void remove_id(DepartmentClass _obj) {
    int saveId = _obj->id;
    ...
};

I was trying to publish my own package and then include it in another project. I had that issue because of how I've built the first module. Im using ES2015 export to create the module, e.g lets say the module looks like that:

export default function(who = 'world'){
    return `Hello ${who}`;
}

After compiled with Babel and before been published:

'use strict';

Object.defineProperty(exports, "__esModule", {
    value: true
});

exports.default = function () {
    var who = arguments.length <= 0 || arguments[0] === undefined ? 'world' : arguments[0];


    return 'Hello ' + who;
};

So after npm install module-name in another project (none ES2015) i had to do

var hello = require('module-name').default;

To actually got the package imported.

Hope that helps!

1) You can put your favicon where you want and add this tag to your page head

<link rel="shortcut icon" href="images/favicon.ico" type="image/x-icon" />

although some browsers will try to get the favicon from /favicon.ico by default, so you should use the IgnoreRoute.

2) If a browser makes a request for the favicon in another directory it will get a 404 error wich is fine and if you have the link tag in answer 1 in your master page the browser will get the favicon you want.

Try this :

new Date().toLocaleString("en-US",Intl.DateTimeFormat().resolvedOptions().timeZone)

This will look for timeZone on your client's browser.

The system I was working on is Windows Server 2008 Standard with IIS 7 (I guess that my experience will apply for all Windows systems of the same age).

Running

C:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe -ir

SEEMED to work, as

C:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe -lv

showed the .Net framework v4 registered with IIS.

But, running the same for .Net v2, namely

C:\Windows\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis.exe -ir

did NOT result in

C:\Windows\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis.exe -lv

showing the framework registered.

(And, for me, the installer for Kofax Capture Network Server was still missing ASP.NET.)

The solution was:

• Open Server Manager
• Go to Roles/Web Server (IIS)
• Push Add Role Services
• check ASP.NET under Application Development (and press Install)

After that, aspnet_regiis.exe -lv (either version) shows the framework registered. (And the Kofax installer was also happy and worked.)

I have used the statement below on debian 10

Based on @jared-burrows' solution. For any package, but passing Context as parameter...

public static String getDataDir(Context context) throws Exception {
    return context.getPackageManager()
            .getPackageInfo(context.getPackageName(), 0)
            .applicationInfo.dataDir;
}

Pure numpy

numpy.loadtxt(open("test.csv", "rb"), delimiter=",", skiprows=1)

Check out the loadtxt documentation.

You can also use python's csv module:

import csv
import numpy
reader = csv.reader(open("test.csv", "rb"), delimiter=",")
x = list(reader)
result = numpy.array(x).astype("float")

You will have to convert it to your favorite numeric type. I guess you can write the whole thing in one line:

result = numpy.array(list(csv.reader(open("test.csv", "rb"), delimiter=","))).astype("float")

Added Hint:

You could also use pandas.io.parsers.read_csv and get the associated numpy array which can be faster.

I've used a simple technique that works nicely for small cases with no special tags and no additional context. Sometimes this comes in handy

{% for i in '0123456789'|make_list %}
    {{ forloop.counter }}
{% endfor %}

I think you can bring specific access to user and command with visudo something like this:

nobody ALL = NOPASSWD: /path/to/osascript myscript.scpt

and with php:

@exec("sudo /path/to/osascript myscript.scpt ");

supposing nobody user is running apache.

This works for me. Returns the number that Excel displays in the bottom status line when a pivot column is filtered and I need the count of the visible cells.

Global Const DashBoardSheet = "DashBoard"
Global Const ProfileColRng = "$L:$L"
.
.
.
Sub MySub()
Dim myreccnt as long
.
.
.
myreccnt = GetFilteredPivotRowCount(DashBoardSheet, ProfileColRng)
.
.
.
End Sub

Function GetFilteredPivotRowCount(sheetname As String, cntrange As String) As long

Dim reccnt As Long

reccnt = Sheets(sheetname).Range(cntrange).SpecialCells(xlCellTypeVisible).SpecialCells(xlCellTypeConstants).Count - 1

GetFilteredPivotRowCount = reccnt

End Function

If someone doesn't want to override default Control Template then here is the solution.

You can create DataTemplate for button which can have TextBlock and then you can write Property trigger on IsMouseOver property to disable mouse over effect. Height of TextBlock and Button should be same.

<Button Background="Black" Margin="0" Padding="0" BorderThickness="0" Cursor="Hand" Height="20">
    <Button.ContentTemplate>
        <DataTemplate>
            <TextBlock Text="GO" Foreground="White" HorizontalAlignment="Center" VerticalAlignment="Center" TextDecorations="Underline" Margin="0" Padding="0" Height="20">
                <TextBlock.Style>
                    <Style TargetType="TextBlock">
                        <Style.Triggers>
                            <Trigger Property ="IsMouseOver" Value="True">
                                <Setter Property= "Background" Value="Black"/>
                            </Trigger>
                        </Style.Triggers>
                    </Style>
                </TextBlock.Style>
            </TextBlock>
        </DataTemplate>
    </Button.ContentTemplate>
</Button>

I solve it running as administrator cmd. Cleaning the cache npm cache clean -f And then try to install the package again

just write '' in place of ' i mean two times '

This is one of the ways:

String toDate = "05/11/2010";

if (new SimpleDateFormat("MM/dd/yyyy").parse(toDate).getTime() / (1000 * 60 * 60 * 24) >= System.currentTimeMillis() / (1000 * 60 * 60 * 24)) {
    System.out.println("Display report.");
} else {
    System.out.println("Don't display report.");
}

A bit more easy interpretable:

String toDateAsString = "05/11/2010";
Date toDate = new SimpleDateFormat("MM/dd/yyyy").parse(toDateAsString);
long toDateAsTimestamp = toDate.getTime();
long currentTimestamp = System.currentTimeMillis();
long getRidOfTime = 1000 * 60 * 60 * 24;
long toDateAsTimestampWithoutTime = toDateAsTimestamp / getRidOfTime;
long currentTimestampWithoutTime = currentTimestamp / getRidOfTime;

if (toDateAsTimestampWithoutTime >= currentTimestampWithoutTime) {
    System.out.println("Display report.");
} else {
    System.out.println("Don't display report.");
}

Oh, as a bonus, the JodaTime's variant:

String toDateAsString = "05/11/2010";
DateTime toDate = DateTimeFormat.forPattern("MM/dd/yyyy").parseDateTime(toDateAsString);
DateTime now = new DateTime();

if (!toDate.toLocalDate().isBefore(now.toLocalDate())) {
    System.out.println("Display report.");
} else {
    System.out.println("Don't display report.");
}

Not sure why, but you can wrap DateTime.ToUniversalTime in a try / catch and achieve the same result in more code.

Good luck.

It is worth trying these 2 options below while we're still waiting for the fix in FF35:

select {
    -moz-appearance: scrollbartrack-vertical;
}

or

select {
    -moz-appearance: treeview;
}

They will just hide any arrow background image you have put in to custom style your select element. So you get a bog standard browser arrow instead of a horrible combo of both browser arrow and your own custom arrow.

Thank you Phil for your solution; in case someone ever gets in the same situation as me, here is a (more complex) variant:

---
# this is just to avoid a call to |default on each iteration
- set_fact:
    postconf_d: {}

- name: 'get postfix default configuration'
  command: 'postconf -d'
  register: command

# the answer of the command give a list of lines such as:
# "key = value" or "key =" when the value is null
- name: 'set postfix default configuration as fact'
  set_fact:
    postconf_d: >
      {{
        postconf_d |
        combine(
          dict([ item.partition('=')[::2]|map('trim') ])
        )
  with_items: command.stdout_lines

This will give the following output (stripped for the example):

"postconf_d": {
    "alias_database": "hash:/etc/aliases", 
    "alias_maps": "hash:/etc/aliases, nis:mail.aliases",
    "allow_min_user": "no", 
    "allow_percent_hack": "yes"
}

Going even further, parse the lists in the 'value':

- name: 'set postfix default configuration as fact'
  set_fact:
    postconf_d: >-
      {% set key, val = item.partition('=')[::2]|map('trim') -%}
      {% if ',' in val -%}
        {% set val = val.split(',')|map('trim')|list -%}
      {% endif -%}
      {{ postfix_default_main_cf | combine({key: val}) }}
  with_items: command.stdout_lines
...

"postconf_d": {
    "alias_database": "hash:/etc/aliases", 
    "alias_maps": [
        "hash:/etc/aliases", 
        "nis:mail.aliases"
    ], 
    "allow_min_user": "no", 
    "allow_percent_hack": "yes"
}

A few things to notice:

• in this case it's needed to "trim" everything (using the >- in YAML and -%} in Jinja), otherwise you'll get an error like:

  FAILED! => {"failed": true, "msg": "|combine expects dictionaries, got u\"  {u'...
  

• obviously the {% if .. is far from bullet-proof

• in the postfix case, val.split(',')|map('trim')|list could have been simplified to val.split(', '), but I wanted to point out the fact you will need to |list otherwise you'll get an error like:

  "|combine expects dictionaries, got u\"{u'...': <generator object do_map at ...
  

Hope this can help.

You don't need root to pull the apk files from /data/app. Sure, you might not have permissions to list the contents of that directory, but you can find the file locations of APKs with:

adb shell pm list packages -f

Then you can use adb pull:

adb pull <APK path from previous command>

and then aapt to get the information you want:

aapt dump badging <pulledfile.apk>

Here is a solution using the javax.crypto library and the apache commons codec library for encoding and decoding in Base64:

import java.security.spec.KeySpec;
import javax.crypto.Cipher;
import javax.crypto.SecretKey;
import javax.crypto.SecretKeyFactory;
import javax.crypto.spec.DESedeKeySpec;
import org.apache.commons.codec.binary.Base64;

public class TrippleDes {

    private static final String UNICODE_FORMAT = "UTF8";
    public static final String DESEDE_ENCRYPTION_SCHEME = "DESede";
    private KeySpec ks;
    private SecretKeyFactory skf;
    private Cipher cipher;
    byte[] arrayBytes;
    private String myEncryptionKey;
    private String myEncryptionScheme;
    SecretKey key;

    public TrippleDes() throws Exception {
        myEncryptionKey = "ThisIsSpartaThisIsSparta";
        myEncryptionScheme = DESEDE_ENCRYPTION_SCHEME;
        arrayBytes = myEncryptionKey.getBytes(UNICODE_FORMAT);
        ks = new DESedeKeySpec(arrayBytes);
        skf = SecretKeyFactory.getInstance(myEncryptionScheme);
        cipher = Cipher.getInstance(myEncryptionScheme);
        key = skf.generateSecret(ks);
    }


    public String encrypt(String unencryptedString) {
        String encryptedString = null;
        try {
            cipher.init(Cipher.ENCRYPT_MODE, key);
            byte[] plainText = unencryptedString.getBytes(UNICODE_FORMAT);
            byte[] encryptedText = cipher.doFinal(plainText);
            encryptedString = new String(Base64.encodeBase64(encryptedText));
        } catch (Exception e) {
            e.printStackTrace();
        }
        return encryptedString;
    }


    public String decrypt(String encryptedString) {
        String decryptedText=null;
        try {
            cipher.init(Cipher.DECRYPT_MODE, key);
            byte[] encryptedText = Base64.decodeBase64(encryptedString);
            byte[] plainText = cipher.doFinal(encryptedText);
            decryptedText= new String(plainText);
        } catch (Exception e) {
            e.printStackTrace();
        }
        return decryptedText;
    }


    public static void main(String args []) throws Exception
    {
        TrippleDes td= new TrippleDes();

        String target="imparator";
        String encrypted=td.encrypt(target);
        String decrypted=td.decrypt(encrypted);

        System.out.println("String To Encrypt: "+ target);
        System.out.println("Encrypted String:" + encrypted);
        System.out.println("Decrypted String:" + decrypted);

    }

}

Running the above program results with the following output:

String To Encrypt: imparator
Encrypted String:FdBNaYWfjpWN9eYghMpbRA==
Decrypted String:imparator

If you want to use curl to download a file from Google Drive, in addition to the file id in drive you also need an OAuth2 access_token for Google Drive API. Getting the token involves several steps with the Google API framework. The sign up steps with Google are (currently) free.

An OAuth2 access_token potentially allows all kinds of activity, so be careful with it. Also, the token times out after a short while (1 hour?) but not short enough to prevent abuse if someone captures it.

Once you have an access_token and the fileid, this will work:

AUTH="Authorization: Bearer the_access_token_goes_here"
FILEID="fileid_goes_here"
URL=https://www.googleapis.com/drive/v3/files/$FILEID?alt=media
curl --header "$AUTH" $URL >myfile.ext

I had this problem, this worked for me:

Install the postgresql-devel package, this will solve the issue of pg_config missing.

sudo apt-get install libpq-dev

The expression a == b should do the job.

this one works for me (plain javascript)

var fixScroll = function (className, border) {  // className = class of scrollElement(s), border: borderTop + borderBottom, due to offsetHeight
var reg = new RegExp(className,"i"); var off = +border + 1;
function _testClass(e) { var o = e.target; while (!reg.test(o.className)) if (!o || o==document) return false; else o = o.parentNode; return o;}
document.ontouchmove  = function(e) { var o = _testClass(e); if (o) { e.stopPropagation(); if (o.scrollTop == 0) { o.scrollTop += 1; e.preventDefault();}}}
document.ontouchstart = function(e) { var o = _testClass(e); if (o && o.scrollHeight >= o.scrollTop + o.offsetHeight - off) o.scrollTop -= off;}
}

fixScroll("fixscroll",2); // assuming I have a 1px border in my DIV

html:

<div class="fixscroll" style="border:1px gray solid">content</div>

That's more specifically a ternary operator expression than an if-then, here's the python syntax

value_when_true if condition else value_when_false

Better Example: (thanks Mr. Burns)

'Yes' if fruit == 'Apple' else 'No'

Now with assignment and contrast with if syntax

fruit = 'Apple'
isApple = True if fruit == 'Apple' else False

vs

fruit = 'Apple'
isApple = False
if fruit == 'Apple' : isApple = True

This is the best tool that you can use for all views and its FREE many thanks to @Jérôme Van Der Linden.

The Android Holo Colors Generator allows you to easily create Android components such as EditText or spinner with your own colours for your Android application. It will generate all necessary nine patch assets plus associated XML drawable and styles which you can copy straight into your project.

http://android-holo-colors.com/

UPDATE 1

This domain seems expired but the project is an open source you can find here

https://github.com/jeromevdl/android-holo-colors

try it

this image put in the background of EditText

android:background="@drawable/textfield_activated"

UPDATE 2

For API 21 or higher, you can use android:backgroundTint

<EditText
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:hint="Underline color change"
        android:backgroundTint="@android:color/holo_red_light" />

Update 3 Now We have with back support AppCompatEditText

Note: We need to use app:backgroundTint instead of android:backgroundTint

<android.support.v7.widget.AppCompatEditText
   android:layout_width="match_parent"
   android:layout_height="wrap_content"
   android:hint="Underline color change"
    app:backgroundTint="@color/blue_gray_light" />

Update 4 AndroidX version

  <androidx.appcompat.widget.AppCompatEditText

    app:backgroundTint="@color/blue_gray_light" />

Depends a lot on your definition of what a "character" is. If "rune equals a character " is OK for your task (generally it isn't) then the answer by VonC is perfect for you. Otherwise, it should be probably noted, that there are few situations where the number of runes in a Unicode string is an interesting value. And even in those situations it's better, if possible, to infer the count while "traversing" the string as the runes are processed to avoid doubling the UTF-8 decode effort.

Here is a slight improvement on the this answer above taking care of both .xlsx and .xls files in the same routine, in case it helps someone!

I also add a line to choose to save with the active sheet name instead of the workbook, which is most practical for me often:

Sub ExportAsCSV()

    Dim MyFileName As String
    Dim CurrentWB As Workbook, TempWB As Workbook

    Set CurrentWB = ActiveWorkbook
    ActiveWorkbook.ActiveSheet.UsedRange.Copy

    Set TempWB = Application.Workbooks.Add(1)
    With TempWB.Sheets(1).Range("A1")
        .PasteSpecial xlPasteValues
        .PasteSpecial xlPasteFormats
    End With

    MyFileName = CurrentWB.Path & "\" & Left(CurrentWB.Name, InStrRev(CurrentWB.Name, ".") - 1) & ".csv"
    'Optionally, comment previous line and uncomment next one to save as the current sheet name
    'MyFileName = CurrentWB.Path & "\" & CurrentWB.ActiveSheet.Name & ".csv"


    Application.DisplayAlerts = False
    TempWB.SaveAs Filename:=MyFileName, FileFormat:=xlCSV, CreateBackup:=False, Local:=True
    TempWB.Close SaveChanges:=False
    Application.DisplayAlerts = True
End Sub

Alternatively you can do like this :

     var _items = from a in StudentsGrades
                  group a by a.Name;

     foreach (var _itemGroup in _items)
     {
        foreach (var _item in _itemGroup.OrderBy(a=>a.grade))
        {
           ------------------------
           --------------------------
        }
     }

What are you using when operate with CLOB?

In all events you can do it with PL/SQL

DECLARE
  str varchar2(32767);
BEGIN
  str := 'Very-very-...-very-very-very-very-very-very long string value';
  update t1 set col1 = str;
END;

If you use "suffixIcon" to collapse the height of the TextField add: suffixIconConstraints

TextField(
                    style: TextStyle(fontSize: r * 1.8, color: Colors.black87),
                    decoration: InputDecoration(
                      isDense: true,
                      contentPadding: EdgeInsets.symmetric(vertical: r * 1.6, horizontal: r * 1.6),
                      suffixIcon: Icon(Icons.search, color: Colors.black54),
                      suffixIconConstraints: BoxConstraints(minWidth: 32, minHeight: 32),
                    ),
                  )

Probably there's something wrong with the input values for X and/or T. The function from the question works ok:

import numpy as np
from math import e

def sigmoid(X, T):
  return 1.0 / (1.0 + np.exp(-1.0 * np.dot(X, T)))

X = np.array([[1, 2, 3], [5, 0, 0]])
T = np.array([[1, 2], [1, 1], [4, 4]])

print(X.dot(T))
# Just to see if values are ok
print([1. / (1. + e ** el) for el in [-5, -10, -15, -16]])
print()
print(sigmoid(X, T))

Result:

[[15 16]
 [ 5 10]]

[0.9933071490757153, 0.9999546021312976, 0.999999694097773, 0.9999998874648379]

[[ 0.99999969  0.99999989]
 [ 0.99330715  0.9999546 ]]

Probably it's the dtype of your input arrays. Changing X to:

X = np.array([[1, 2, 3], [5, 0, 0]], dtype=object)

Gives:

Traceback (most recent call last):
  File "/[...]/stackoverflow_sigmoid.py", line 24, in <module>
    print sigmoid(X, T)
  File "/[...]/stackoverflow_sigmoid.py", line 14, in sigmoid
    return 1.0 / (1.0 + np.exp(-1.0 * np.dot(X, T)))
AttributeError: exp

Using zip4j you can simply do this

ZipFile zipfile = new ZipFile(new File("D:\\reports\\january\\filename.zip"));
zipfile.addFolder(new File("D:\\reports\\january\\"));

It will archive your folder and everything in it.

Use the .extractAll method to get it all out:

zipfile.extractAll("D:\\destination_directory");

Yes, ( ) captures a group. You can use it again with $i where i is the i'th capture group.

So:

search: (\w+\.someMethod\(\))

replace: ((TypeName)$1)

Hint: Ctrl + Space in the textboxes gives you all kinds of suggestions for regular expression writing.

Here is code to get line number and column position

function getLineNumber(tArea) {

    return tArea.value.substr(0, tArea.selectionStart).split("\n").length;
}

function getCursorPos() {
    var me = $("textarea[name='documenttext']")[0];
    var el = $(me).get(0);
    var pos = 0;
    if ('selectionStart' in el) {
        pos = el.selectionStart;
    } else if ('selection' in document) {
        el.focus();
        var Sel = document.selection.createRange();
        var SelLength = document.selection.createRange().text.length;
        Sel.moveStart('character', -el.value.length);
        pos = Sel.text.length - SelLength;
    }
    var ret = pos - prevLine(me);
    alert(ret);

    return ret; 
}

function prevLine(me) {
    var lineArr = me.value.substr(0, me.selectionStart).split("\n");

    var numChars = 0;

    for (var i = 0; i < lineArr.length-1; i++) {
        numChars += lineArr[i].length+1;
    }

    return numChars;
}

tArea is the text area DOM element

It seems that your project is written in Python < 3. This is because the file() builtin function is removed in Python 3. Try using Python 2to3 tool or edit the erroneous file yourself.

EDIT: BTW, the project page clearly mentions that

Gunicorn requires Python 2.x >= 2.5. Python 3.x support is planned.

Boolean b = Boolean.valueOf(string);

The value of b is true if the string is not a null and equal to true (ignoring case).

SELECT CAST(GETDATE() AS DATE)

Returns the current date with the time part removed.

DATETIMEs are not "stored in the following format". They are stored in a binary format.

SELECT CAST(GETDATE() AS BINARY(8))

The display format in the question is independent of storage.

Formatting into a particular display format should be done by your application.

Recently ran into a problem with this and a Chrome extension that was corrupting a JSON stream when the response header labeled the content-type as 'text/html' apparently extensions can and will use the response header to alter the content prior to further processing by the browser. Changing the content-type fixed the issue.

One simple thing you could do is abstract the test inside a function.

local function isempty(s)
  return s == nil or s == ''
end

if isempty(foo) then
  foo = "default value"
end

If you have readonly attribute, blur by itself would not work. Contraption below should do the job.

$('#myInputID').removeAttr('readonly').trigger('blur').attr('readonly','readonly');

Ok, personal opinion here, but Append and Prepend imply precise positions in a set.

Push and Pop are really concepts that can be applied to either end of a set... Just as long as you're consistent... For some reason, to me, Push() seems like it should apply to the front of a set...

No need to trying reinvent the wheel, as this is common greatest-n-per-group problem. Very nice solution is presented.

I prefer the most simplistic solution (see SQLFiddle, updated Justin's) without subqueries (thus easy to use in views):

SELECT t1.*
FROM lms_attendance AS t1
LEFT OUTER JOIN lms_attendance AS t2
  ON t1.user = t2.user 
        AND (t1.time < t2.time 
         OR (t1.time = t2.time AND t1.Id < t2.Id))
WHERE t2.user IS NULL

This also works in a case where there are two different records with the same greatest value within the same group - thanks to the trick with (t1.time = t2.time AND t1.Id < t2.Id). All I am doing here is to assure that in case when two records of the same user have same time only one is chosen. Doesn't actually matter if the criteria is Id or something else - basically any criteria that is guaranteed to be unique would make the job here.

Yes, it's called next.

for i in 0..5
   if i < 2
     next
   end
   puts "Value of local variable is #{i}"
end

This outputs the following:

I had the same problem as deke. I forgot to include the most important script: angular.js :)

<script type="text/javascript" src="bower_components/angular/angular.min.js"></script>

This answer is not the direct answer for the question. But it should help you figure out which solution fits best for your problem.

When analysing the problem you should activate the debug option -vv

Then rsync will output which files are included or excluded by which pattern:

building file list ... 
[sender] hiding file FILE1 because of pattern FILE1*
[sender] showing file FILE2 because of pattern *

Here is an IFrame solution that works for IE and Chrome:

function printHTML(htmlString) {
    var newIframe = document.createElement('iframe');
    newIframe.width = '1px';
    newIframe.height = '1px';
    newIframe.src = 'about:blank';

    // for IE wait for the IFrame to load so we can access contentWindow.document.body
    newIframe.onload = function() {
        var script_tag = newIframe.contentWindow.document.createElement("script");
        script_tag.type = "text/javascript";
        var script = newIframe.contentWindow.document.createTextNode('function Print(){ window.focus(); window.print(); }');
        script_tag.appendChild(script);

        newIframe.contentWindow.document.body.innerHTML = htmlString;
        newIframe.contentWindow.document.body.appendChild(script_tag);

        // for chrome, a timeout for loading large amounts of content
        setTimeout(function() {
            newIframe.contentWindow.Print();
            newIframe.contentWindow.document.body.removeChild(script_tag);
            newIframe.parentElement.removeChild(newIframe);
        }, 200);
    };
    document.body.appendChild(newIframe);
}

I read it something like:

If still on the conditions to run the loop, do stuff, else do something else.

use href with indexof

<script type="text/javascript">
 $(document).ready(function () {
   if(window.location.href.indexOf("added-to-cart=555") > -1) {
   alert("your url contains the added-to-cart=555");
  }
});
</script>

The code overlooks calling the function move_uploaded_file() which would check whether the indicated file is valid for uploading.

You may wish to review a simple example at:

http://www.w3schools.com/php/php_file_upload.asp

If you are just doing it for display, you can build an array from the digits before they're rounded.

var num = Math.pow(2, 100);
var reconstruct = [];
while(num > 0) {
    reconstruct.unshift(num % 10);
    num = Math.floor(num / 10);
}
console.log(reconstruct.join(''));

The problem you will have is with collections where unicity of elements is calculated according to both .equals() and .hashCode(), for instance keys in a HashMap.

As its name implies, it relies on hash tables, and hash buckets are a function of the object's .hashCode().

If you have two objects which are .equals(), but have different hash codes, you lose!

The part of the contract here which is important is: objects which are .equals() MUST have the same .hashCode().

This is all documented in the javadoc for Object. And Joshua Bloch says you must do it in Effective Java. Enough said.

For Windows 10 it is:

yurzui's answer didn't work for me, it might be a different RC version, or it might be a mistake on my part. Either way, here's how I did it with my component in Angular2 RC4 (which is now quite outdated).

@Component({
    ...
    host: {
        '(document:keydown)': 'handleKeyboardEvents($event)'
    }
})
export class MyComponent {
    ...
    handleKeyboardEvents(event: KeyboardEvent) {
        this.key = event.which || event.keyCode;
    }
}

Easiest way would probably be with jQuery, as follows:

$(document).ready(function(){
  $("#_1234").attr("checked","checked");
})

This adds a new attribute "checked" (which in HTML does not need a value). Just remember to include the jQuery library:

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>

My problem in this case was a simple instance of having a dumb null pointer exception in one of my methods that was being invoked later in the lifecycle. This was causing the "Error inflating class fragment" exception for me. In short, please remember to check the further down the exception stack trace for a possible cause.

Once I resolved the null pointer exception, my fragment loaded fine.

For versions of data.table >= 1.9.8, the following all just work:

library(data.table)
dt <- data.table(a = 1, b = 2, c = 3)

# select single column by index
dt[, 2]
#    b
# 1: 2

# select multiple columns by index
dt[, 2:3]
#    b c
# 1: 2 3

# select single column by name
dt[, "a"]
#    a
# 1: 1

# select multiple columns by name
dt[, c("a", "b")]
#    a b
# 1: 1 2

For versions of data.table < 1.9.8 (for which numerical column selection required the use of with = FALSE), see this previous version of this answer. See also NEWS on v1.9.8, POTENTIALLY BREAKING CHANGES, point 3.

Yo can use joda time.

private Date dateWitoutTime(Date date){
 return new LocalDate(date).toDate()
}

and you call with:

Date date = new Date();
System.out.println("Without Time = " + dateWitoutTime(date) + "/n  With time = " + date);

Use the btoa() function to encode:

console.log(btoa("password")); // cGFzc3dvcmQ=

To decode, you can use the atob() function:

console.log(atob("cGFzc3dvcmQ=")); // password

On Scientific Linux 6 (similar to CentOS 6-- SL is now replaced by CentOS, AIUI), I had to use /usr/sbin/prelink -av -mR which I found suggested at https://stelfox.net/blog/2014/08/dependency-prelink-issues/

Until I did that, I got a cc1 error gcc: error trying to exec 'cc1': execvp: No such file or directory when I tried to compile, and gcc --version reported 4.2.2 instead of 4.4.7, despite that version being reported by yum.

It may or may not be related, but the system had run out of space on /var

var data = [
    {
        id : "001",
        name : "apple",
        category : "fruit",
        color : "red"
    },
    {
        id : "002",
        name : "melon",
        category : "fruit",
        color : "green"
    },
    {
        id : "003",
        name : "banana",
        category : "fruit",
        color : "yellow"
    }
];

for(var i = 0, len = data.length; i < length; i++) {
    var temp = '<tr><td>' + data[i].id + '</td>';
    temp+= '<td>' + data[i].name+ '</td>';
    temp+= '<td>' + data[i].category + '</td>';
    temp+= '<td>' + data[i].color + '</td></tr>';
    $('table tbody').append(temp));
}

The design of HTTP means that making a POST with data will return a page. The original designers probably intended for that to be a "result" page of your POST.

It is normal for a PHP application to POST back to the same page as it can not only process the POST request, but it can generate an updated page based on the original GET but with the new information from the POST. However, there's nothing stopping your server code from providing completely different output. Alternatively, you could POST to an entirely different page.

If you don't want the output, one method that I've seen before AJAX took off was for the server to return a HTTP response code of (I think) 250. This is called "No Content" and this should make the browser ignore the data.

Of course, the third method is to make an AJAX call with your submitted data, instead.

C#'s const is the exact same thing as Java's final, except it's absolutely always static. In my opinion, it's not really necessary for a const variable to be non-static, but if you need to access a const variable non-static-ly, you can do:

class MyClass
{    
    private const int myLowercase_Private_Const_Int = 0;
    public const int MyUppercase_Public_Const_Int = 0;

    /*        
      You can have the `private const int` lowercase 
      and the `public int` Uppercase:
    */
    public int MyLowercase_Private_Const_Int
    {
        get
        {
            return MyClass.myLowercase_Private_Const_Int;
        }
    }  

    /*
      Or you can have the `public const int` uppercase 
      and the `public int` slighly altered
      (i.e. an underscore preceding the name):
    */
    public int _MyUppercase_Public_Const_Int
    {
        get
        {
            return MyClass.MyUppercase_Public_Const_Int;
        }
    } 

    /*
      Or you can have the `public const int` uppercase 
      and get the `public int` with a 'Get' method:
    */
    public int Get_MyUppercase_Public_Const_Int()
    {
        return MyClass.MyUppercase_Public_Const_Int;
    }    
}

Well, now I realize this question was asked 4 years ago, but since I put around 2 hours of work, consisting of trying all sorts of different ways of answering and code formatting, into this answer, I'm still posting it. :)

But, for the record, I still feel kinda silly.

You can use your own isEmpty (for multiple collection) method too. Add this your Util class.

public static boolean isEmpty(Collection... collections) {
    for (Collection collection : collections) {
        if (null == collection || collection.isEmpty())
            return true;
    }
    return false;
}

You are referring to the section "2.3.5 Deploying the demo app" of this "Ruby on Rails Tutorial ":

In section 2.3.1 Planning the application, note that they did:

$ git remote add origin [email protected]:<username>/demo_app.git
$ git push origin master

That is why a simple git push worked (using here an ssh address).
Did you follow that step and made that first push?

 www.github.com/levelone/demo_app

wouldn't be a writable URI for pushing to a GitHub repo.

https://[email protected]/levelone/demo_app.git

should be more appropriate.
Check what git remote -v returns, and if you need to replace the remote address, as described in GitHub help page, use git remote --set-url.

git remote set-url origin https://[email protected]/levelone/demo_app.git
or 
git remote set-url origin [email protected]:levelone/demo_app.git

It would appear this is not possible, or at least not supported.

From the HTML5 specification:

When used to include data blocks (as opposed to scripts), the data must be embedded inline, the format of the data must be given using the type attribute, the src attribute must not be specified, and the contents of the script element must conform to the requirements defined for the format used.

If you want the output to be

array([1.6e-01, 9.9e-01, 3.6e-04])

the problem is not really a missing feature of NumPy, but rather that this sort of rounding is not a standard thing to do. You can make your own rounding function which achieves this like so:

def my_round(value, N):
    exponent = np.ceil(np.log10(value))
    return 10**exponent*np.round(value*10**(-exponent), N)

For a general solution handling 0 and negative values as well, you can do something like this:

def my_round(value, N):
    value = np.asarray(value).copy()
    zero_mask = (value == 0)
    value[zero_mask] = 1.0
    sign_mask = (value < 0)
    value[sign_mask] *= -1
    exponent = np.ceil(np.log10(value))
    result = 10**exponent*np.round(value*10**(-exponent), N)
    result[sign_mask] *= -1
    result[zero_mask] = 0.0
    return result

you can do something like this:

DataTable dt = new DataTable();
for (int i = 0; i < GridView1.Columns.Count; i++)
    {
        dt.Columns.Add("column"+i.ToString());
    }
foreach (GridViewRow row in GridView1.Rows)
    {
        DataRow dr = dt.NewRow();
        for(int j = 0;j<GridView1.Columns.Count;j++)
            {
                dr["column" + j.ToString()] = row.Cells[j].Text;
            }

            dt.Rows.Add(dr);
    }

And that will show that it works.

GridView6.DataSource = dt;
GridView6.DataBind();

You could define a clone function.

I use this one :

function goclone(source) {
    if (Object.prototype.toString.call(source) === '[object Array]') {
        var clone = [];
        for (var i=0; i<source.length; i++) {
            clone[i] = goclone(source[i]);
        }
        return clone;
    } else if (typeof(source)=="object") {
        var clone = {};
        for (var prop in source) {
            if (source.hasOwnProperty(prop)) {
                clone[prop] = goclone(source[prop]);
            }
        }
        return clone;
    } else {
        return source;
    }
}

var B = goclone(A);

It doesn't copy the prototype, functions, and so on. But you should adapt it (and maybe simplify it) for you own need.

read filename ;
sed -i 's/letter/newletter/g' "$filename" #letter

^use as many of these as you need, and you can make your own BASIC encryption

I recently used this to read all the lines from a file:

alist = open('maze.txt').read().split()

or you can use this for that little bit of extra added safety:

with f as open('maze.txt'):
    alist = f.read().split()

It doesn't work with whitespace in-between text in a single line, but it looks like your example file might not have whitespace splitting the values. It is a simple solution and it returns an accurate list of values, and does not add an empty string: '' for every empty line, such as a newline at the end of the file.

Just add this to your recycleview in xml

 android:nestedScrollingEnabled="false"

like this

<android.support.v7.widget.RecyclerView
                    android:background="#ffffff"
                    android:id="@+id/myrecycle"
                    android:layout_width="match_parent"
                    android:layout_height="match_parent"
                    android:nestedScrollingEnabled="false">

Your element does not have an ID but just a name. So you could either use getElementsByName() method to get a list of all elements with this name:

var jobValue = document.getElementsByName('txtJob')[0].value  // first element in DOM  (index 0) with name="txtJob"

Or you assign an ID to the element:

<input type="text" name="txtJob" id="txtJob" value="software engineer">

If you really want an exe Excelsior JET is a professional level product that compiles to native code:

http://www.excelsior-usa.com/jet.html

You can also look at JSMooth:

http://jsmooth.sourceforge.net/

And if your application is compatible with its compatible with AWT/Apache classpath then GCJ compiles to native exe.

Although most of the points are already discussed. But I would like to highlight again one more reason for NaN which is missing.

tf.estimator.DNNClassifier(
    hidden_units, feature_columns, model_dir=None, n_classes=2, weight_column=None,
    label_vocabulary=None, optimizer='Adagrad', activation_fn=tf.nn.relu,
    dropout=None, config=None, warm_start_from=None,
    loss_reduction=losses_utils.ReductionV2.SUM_OVER_BATCH_SIZE, batch_norm=False
)

By default activation function is "Relu". It could be possible that intermediate layer's generating a negative value and "Relu" convert it into the 0. Which gradually stops training.

I observed the "LeakyRelu" able to solve such problems.

You need to apply the event handler in the context of that element:

var elem = document.getElementById("linkid");
if (typeof elem.onclick == "function") {
    elem.onclick.apply(elem);
}

Otherwise this would reference the context the above code is executed in.

A simple (and maybe simplistic) answer to the question is the content of $x numeric is the following:

if ($x  eq  $x+0) { .... }

It does a textual comparison of the original $x with the $x converted to a numeric value.

Check the file in <TOMCAT_HOME>/conf named tomcat-users.xml.
If you don't find something there edit to look something like:

<?xml version='1.0' encoding='utf-8'?>
<tomcat-users>
  <role rolename="admin"/>
  <user username="admin" password="password" roles="standard,manager,admin"/>
</tomcat-users>

Better yet, put --user-install in your ~/.gemrc file so you don't have to type it every time

gem: --user-install

In Addition to the above answers, there probably should be noted that there is a legacy way to implement the initialization. There is an interface called Initializable from the fxml library.

import javafx.fxml.Initializable;

class MyController implements Initializable {
    @FXML private TableView<MyModel> tableView;

    @Override
    public void initialize(URL location, ResourceBundle resources) {
        tableView.getItems().addAll(getDataFromSource());
    }
}

Parameters:

location - The location used to resolve relative paths for the root object, or null if the location is not known.
resources - The resources used to localize the root object, or null if the root object was not localized. 

And the note of the docs why the simple way of using @FXML public void initialize() works:

NOTE This interface has been superseded by automatic injection of location and resources properties into the controller. FXMLLoader will now automatically call any suitably annotated no-arg initialize() method defined by the controller. It is recommended that the injection approach be used whenever possible.

Changing

RestResponse response = client.Execute(request);

to

IRestResponse response = client.Execute(request);

worked for me.

The following works for me

const mongoose = require('mongoose');

mongoose.connect("mongodb://localhost/playground", { useNewUrlParser: true,useUnifiedTopology: true })
.then(res => console.log('Connected to db'));

The mongoose version is 5.8.10.

For me DownloadSVN is the best SVN client no install no explore shell integration so no need to worry about system instability small and very light weight and it does a great job just recently i had a very bad experience with TortoiseSVN on my WindowsXP_x86:) luckily i found this great SVN client

curl --head https://www.example.net

I was pointed to this by curl itself; when I issued the command with -X HEAD, it printed:

Warning: Setting custom HTTP method to HEAD with -X/--request may not work the 
Warning: way you want. Consider using -I/--head instead.

Since there can be multiple columns with same name , we should first rename the columns. Here is code for the solution.

df.columns=list(range(0,len(df.columns)))
df.drop(columns=[1,2])#drop second and third columns

If you have Pillow installed with scipy and it is still giving you error then check your scipy version because it has been removed from scipy since 1.3.0rc1.

rather install scipy 1.1.0 by :

pip install scipy==1.1.0

check https://github.com/scipy/scipy/issues/6212

The method imread in scipy.misc requires the forked package of PIL named Pillow. If you are having problem installing the right version of PIL try using imread in other packages:

from matplotlib.pyplot import imread
im = imread(image.png)

To read jpg images without PIL use:

import cv2 as cv
im = cv.imread(image.jpg)

You can try from scipy.misc.pilutil import imread instead of from scipy.misc import imread

First of all you should fix modal HTML structure. Now it's not correct, you don't need class .hide:

<div id="edit-modal" class="modal fade" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
    <div class="modal-dialog">
        <div class="modal-content">
            <div class="modal-header">
                <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>
                <h4 class="modal-title" id="myModalLabel">Modal title</h4>
            </div>
            <div class="modal-body edit-content">
                ...
            </div>
            <div class="modal-footer">
                <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
                <button type="button" class="btn btn-primary">Save changes</button>
            </div>
        </div>
    </div>
</div>

Then links should point to this modal via data-target attribute:

<a href="#myModal" data-toggle="modal" id="1" data-target="#edit-modal">Edit 1</a>

Finally Js part becomes very simple:

    $('#edit-modal').on('show.bs.modal', function(e) {

        var $modal = $(this),
            esseyId = e.relatedTarget.id;

        $.ajax({
            cache: false,
            type: 'POST',
            url: 'backend.php',
            data: 'EID=' + essayId,
            success: function(data) {
                $modal.find('.edit-content').html(data);
            }
        });
    })

ASCII defines 128 characters, as Unicode contains a repertoire of more than 120,000 characters.

If you don't have lodash in your project it will be an overkill to add the whole library just to use one function. This is the most sophisticated solution of your problem I've ever seen.

_.padStart(num, 2, '0')

The correct way to install it would be as mentioned here

$ pip install --upgrade TF_BINARY_URL   # Python 2.7
$ pip3 install --upgrade TF_BINARY_URL  # Python 3.N

Find the correct TF_BINARY_URL for your hardware from the tensor flow official homepage

This above does not work because sometimes

$(this).attr('checked') == undefined

adjust your code with

if(!$(this).attr('checked') || $(this).attr('checked') == false){

this is what worked for me (yes I was having the same problem) were is says something like java -Xmx3G -Xms3G put java -Xmx1024M so the run.bat should look like java -Xmx1024M -jar craftbukkit.jar -o false PAUSE

Something like this?

<a href="#" onClick="MyWindow=window.open('http://www.google.com','MyWindow','width=600,height=300'); return false;">Click Here</a>

You are almost certainly running your code before the DOM is constructed. Try running your code in a window.onload handler function (but see note below):

window.onload = function() {
    // all of your code goes in here
    // it runs after the DOM is built
}

Another popular cross-browser solution is to put your <script> block just before the closing </body> tag. This could be the best solution for you, depending on your needs:

<html>
  <body>

    <!-- all of your HTML goes here... -->

    <script>
        // code in this final script element can use all of the DOM
    </script>
  </body>
</html>

• Note that window.onload will wait until all images and subframes have loaded, which might be a long time after the DOM is built. You could also use document.addEventListener("DOMContentLoaded", function(){...}) to avoid this problem, but this is not supported cross-browser. The bottom-of-body trick is both cross-browser and runs as soon as the DOM is complete.

In the web a stateful protocol is based on having a temporary token that is exchanged between a browser and a server (via cookie header or URI rewriting) on every request. That token is usually created on the server end, and it is a piece of opaque data that has a certain time-to-live, and it has the sole purpose of identifying a specific web user agent. That is, the token is temporary, and becomes a STATE that the web server has to maintain on behalf of a client user agent during the duration of that conversation. Therefore, the communication using a token in this way is STATEFUL. And if the conversation between client and server is STATEFUL it is not RESTful.

The username/password (sent on the Authorization header) is usually persisted on the database with the intent of identifying a user. Sometimes the user could mean another application; however, the username/password is NEVER intended to identify a specific web client user agent. The conversation between a web agent and server based on using the username/password in the Authorization header (following the HTTP Basic Authorization) is STATELESS because the web server front-end is not creating or maintaining any STATE information whatsoever on behalf of a specific web client user agent. And based on my understanding of REST, the protocol states clearly that the conversation between clients and server should be STATELESS. Therefore, if we want to have a true RESTful service we should use username/password (Refer to RFC mentioned in my previous post) in the Authorization header for every single call, NOT a sension kind of token (e.g. Session tokens created in web servers, OAuth tokens created in authorization servers, and so on).

I understand that several called REST providers are using tokens like OAuth1 or OAuth2 accept-tokens to be be passed as "Authorization: Bearer " in HTTP headers. However, it appears to me that using those tokens for RESTful services would violate the true STATELESS meaning that REST embraces; because those tokens are temporary piece of data created/maintained on the server side to identify a specific web client user agent for the valid duration of a that web client/server conversation. Therefore, any service that is using those OAuth1/2 tokens should not be called REST if we want to stick to the TRUE meaning of a STATELESS protocol.

There was a vicious cycle as assembly became less commonplace: as higher level languages matured, assembly language instruction sets were built less for programmer convenience and more for the convenience of compilers.

So now, realistically, it may be very hard to make the right decisions on, say, which registers you should use or which instructions are slightly more efficient. Compilers can use heuristics to figure out which tradeoffs are likely to have the best payoff. We can probably think through smaller problems and find local optimizations that might beat our now pretty sophisticated compilers, but odds are that in the average case, a good compiler will do a better job on the first try than a good programmer probably will. Eventually, like John Henry, we might beat the machine, but we might seriously burn ourselves out getting there.

Our problems are also now quite different. In 1986 I was trying to figure out how to get a little more speed out of small programs that involved putting a few hundred pixels on the screen; I wanted the animation to be less jerky. A fair case for assembly language. Now I'm trying to figure out how to represent abstractions around contract language and servicer policy for mortgages, and I'd rather read something that looks close to the language that the business folks speak. Unlike LISP macros, Assembly macros don't enforce much in the way of rules, so even though you might be able to get something reasonably close to a DSL in a good assembler, it'll be prone to all sorts of quirks that won't cause me problems if I wrote the same code in Ruby, Boo, Lisp, C# or even F#.

If your problems are easy to express in efficient assembly language, though, more power to you.

In my experience it's best to put as much code as you can into well-named modules, and only put as much code as you need to into the actual worksheet objects.

Example: Any code that uses worksheet events like Worksheet_SelectionChange or Worksheet_Calculate.

No need for css, you can just use the HR tag from HTML

<hr />

Using this CSS for my current site. It works perfect!

#sides{
margin:0;
}
#left{
float:left;
width:75%;
overflow:hidden;
}
#right{
float:left;
width:25%;
overflow:hidden;
} 

I dump my output to a text file. I then open it in notepad ++ then click the show all characters button. Not very elegant but it works.

For simplicity, if you do not want send a message, try this

$new_string = substr( $dynamicstring, -min( strlen( $dynamicstring ), 7 ) );

You have to be clear on what you mean by "JSON".

Some people use the term JSON incorrectly to refer to a plain old JavaScript object, such as [{a: 1}]. This one happens to be an array. If you want to add a new element to the array, just push it, as in

var arr = [{a: 1}];
arr.push({b: 2});

< [{a: 1}, {b: 2}]

The word JSON may also be used to refer to a string which is encoded in JSON format:

var json = '[{"a": 1}]';

Note the (single) quotation marks indicating that this is a string. If you have such a string that you obtained from somewhere, you need to first parse it into a JavaScript object, using JSON.parse:

var obj = JSON.parse(json);

Now you can manipulate the object any way you want, including push as shown above. If you then want to put it back into a JSON string, then you use JSON.stringify:

var new_json = JSON.stringify(obj.push({b: 2}));
'[{"a": 1}, {"b": 1}]'

JSON is also used as a common way to format data for transmission of data to and from a server, where it can be saved (persisted). This is where ajax comes in. Ajax is used both to obtain data, often in JSON format, from a server, and/or to send data in JSON format up to to the server. If you received a response from an ajax request which is JSON format, you may need to JSON.parse it as described above. Then you can manipulate the object, put it back into JSON format with JSON.stringify, and use another ajax call to send the data to the server for storage or other manipulation.

You use the term "JSON file". Normally, the word "file" is used to refer to a physical file on some device (not a string you are dealing with in your code, or a JavaScript object). The browser has no access to physical files on your machine. It cannot read or write them. Actually, the browser does not even really have the notion of a "file". Thus, you cannot just read or write some JSON file on your local machine. If you are sending JSON to and from a server, then of course, the server might be storing the JSON as a file, but more likely the server would be constructing the JSON based on some ajax request, based on data it retrieves from a database, or decoding the JSON in some ajax request, and then storing the relevant data back into its database.

Do you really have a "JSON file", and if so, where does it exist and where did you get it from? Do you have a JSON-format string, that you need to parse, mainpulate, and turn back into a new JSON-format string? Do you need to get JSON from the server, and modify it and then send it back to the server? Or is your "JSON file" actually just a JavaScript object, that you simply need to manipulate with normal JavaScript logic?

For example, lets say we want to display only the first 10 items of an array, we could do this using the SlicePipe like so:

<ul>
     <li *ngFor="let item of items | slice:0:10">
      {{ item }}
     </li>
</ul>

for winforms .NET change DropDownStyle to DropDownList from Combobox property

EncloseJS.

You get a fully functional binary without sources.

Native modules also supported. (must be placed in the same folder)

JavaScript code is transformed into native code at compile-time using V8 internal compiler. Hence, your sources are not required to execute the binary, and they are not packaged.

Perfectly optimized native code can be generated only at run-time based on the client's machine. Without that info EncloseJS can generate only "unoptimized" code. It runs about 2x slower than NodeJS.

Also, node.js runtime code is put inside the executable (along with your code) to support node API for your application at run-time.

Use cases:

• Make a commercial version of your application without sources.
• Make a demo/evaluation/trial version of your app without sources.
• Make some kind of self-extracting archive or installer.
• Make a closed source GUI application using node-thrust.
• No need to install node and npm to deploy the compiled application.
• No need to download hundreds of files via npm install to deploy your application. Deploy it as a single independent file.
• Put your assets inside the executable to make it even more portable. Test your app against new node version without installing it.

If you want to migrate a #git repository from one server to a new one you can do it like this:

git clone OLD_REPOSITORY_PATH
cd OLD_REPOSITORY_DIR
git remote add NEW_REPOSITORY_ALIAS  NEW_REPOSITORY_PATH
#check out all remote branches 
for remote in `git branch -r | grep -v master `; do git checkout --track $remote ; done
git push --mirror NEW_REPOSITORY_PATH
git push NEW_REPOSITORY_ALIAS --tags

All remote branches and tags from the old repository will be copied to the new repository.

Running this command alone:

git push NEW_REPOSITORY_ALIAS

would only copy a master branch (only tracking branches) to the new repository.

Environment.ProcessorCount should give you the number of cores on the local machine.

With tr:

# Converts upper to lower case 
$ tr '[:upper:]' '[:lower:]' < input.txt > output.txt

# Converts lower to upper case
$ tr '[:lower:]' '[:upper:]' < input.txt > output.txt

Or, sed on GNU (but not BSD or Mac as they don't support \L or \U):

# Converts upper to lower case
$ sed -e 's/\(.*\)/\L\1/' input.txt > output.txt

# Converts lower to upper case
$ sed -e 's/\(.*\)/\U\1/' input.txt > output.txt
 

When a module is loaded from a file in Python, __file__ is set to its path. You can then use that with other functions to find the directory that the file is located in.

Taking your examples one at a time:

A = os.path.join(os.path.dirname(__file__), '..')
# A is the parent directory of the directory where program resides.

B = os.path.dirname(os.path.realpath(__file__))
# B is the canonicalised (?) directory where the program resides.

C = os.path.abspath(os.path.dirname(__file__))
# C is the absolute path of the directory where the program resides.

You can see the various values returned from these here:

import os
print(__file__)
print(os.path.join(os.path.dirname(__file__), '..'))
print(os.path.dirname(os.path.realpath(__file__)))
print(os.path.abspath(os.path.dirname(__file__)))

and make sure you run it from different locations (such as ./text.py, ~/python/text.py and so forth) to see what difference that makes.

I just want to address some confusion first. __file__ is not a wildcard it is an attribute. Double underscore attributes and methods are considered to be "special" by convention and serve a special purpose.

http://docs.python.org/reference/datamodel.html shows many of the special methods and attributes, if not all of them.

In this case __file__ is an attribute of a module (a module object). In Python a .py file is a module. So import amodule will have an attribute of __file__ which means different things under difference circumstances.

Taken from the docs:

__file__ is the pathname of the file from which the module was loaded, if it was loaded from a file. The __file__ attribute is not present for C modules that are statically linked into the interpreter; for extension modules loaded dynamically from a shared library, it is the pathname of the shared library file.

In your case the module is accessing it's own __file__ attribute in the global namespace.

To see this in action try:

# file: test.py

print globals()
print __file__

And run:

python test.py

{'__builtins__': <module '__builtin__' (built-in)>, '__name__': '__main__', '__file__':
 'test_print__file__.py', '__doc__': None, '__package__': None}
test_print__file__.py

If you are trying to achieve horizontal div scrolling with touch on mobile, the updated CSS fix does not work (tested on Android Chrome and iOS Safari multiple versions), eg:

-webkit-overflow-scrolling: touch

I found a solution and modified it for horizontal scrolling from before the CSS trick. I've tested it on Android Chrome and iOS Safari and the listener touch events have been around a long time, so it has good support: http://caniuse.com/#feat=touch.

Usage:

touchHorizScroll('divIDtoScroll');

Functions:

function touchHorizScroll(id){
    if(isTouchDevice()){ //if touch events exist...
        var el=document.getElementById(id);
        var scrollStartPos=0;

        document.getElementById(id).addEventListener("touchstart", function(event) {
            scrollStartPos=this.scrollLeft+event.touches[0].pageX;              
        },false);

        document.getElementById(id).addEventListener("touchmove", function(event) {
            this.scrollLeft=scrollStartPos-event.touches[0].pageX;              
        },false);
    }
}
function isTouchDevice(){
    try{
        document.createEvent("TouchEvent");
        return true;
    }catch(e){
        return false;
    }
}  

Modified from vertical solution (pre CSS trick):

http://chris-barr.com/2010/05/scrolling_a_overflowauto_element_on_a_touch_screen_device/

Consider this:

function group1k(s) {
    return (""+s)
        .replace(/(\d+)(\d{3})(\d{3})$/  ,"$1 $2 $3" )
        .replace(/(\d+)(\d{3})$/         ,"$1 $2"    )
        .replace(/(\d+)(\d{3})(\d{3})\./ ,"$1 $2 $3.")
        .replace(/(\d+)(\d{3})\./        ,"$1 $2."   )
    ;
}

It's a quick solution for anything under 999.999.999, which is usually enough. I know the drawbacks and I'm not saying this is the ultimate weapon - but it's just as fast as the others above and I find this one more readable. If you don't need decimals you can simplify it even more:

function group1k(s) {
    return (""+s)
        .replace(/(\d+)(\d{3})(\d{3})$/ ,"$1 $2 $3")
        .replace(/(\d+)(\d{3})$/        ,"$1 $2"   )
    ;
}

Isn't it handy.

PercentRelativeLayout is deprecated from Revision 26.0.0 of support Library.

Google introduced new Layout called ConstraintLayout.

Add the library as a dependency in your module-level build.gradle file:

     dependencies {
        compile 'com.android.support.constraint:constraint-layout:1.0.1'
      }

just add in a layout file:

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
</android.support.constraint.ConstraintLayout>

Constraints

Constraints help you keep widgets aligned. You can use anchors, such as the constraint handles shown below, to determine alignment rules between various widgets.

1. Wrap Content: The view expands as needed to fit its contents.
2. Match Constraints: The view expands as needed to meet the definition of its constraints after accounting for margins. However, if the given dimension has only one constraint, then the view expands to fit its contents. Using this mode on either the height or width also allows you to set a size ratio.
3. Fixed: You specify a specific dimension in the text box below or by resizing the view in the editor.
4. Spread: The views are evenly distributed (after margins are accounted for). This is the default.
5. Spread inside: The first and last view are affixed to the constraints on each end of the chain and the rest are evenly distributed.
6. Weighted: When the chain is set to either spread or spread inside, you can fill the remaining space by setting one or more views to "match constraints" (0dp). By default, the space is evenly distributed between each view that's set to "match constraints," but you can assign a weight of importance to each view using the layout_constraintHorizontal_weight and layout_constraintVertical_weight attributes. If you're familiar with layout_weight in a linear layout, this works the same way. So the view with the highest weight value gets the most amount of space; views that have the same weight get the same amount of space.
7. Packed: The views are packed together (after margins are accounted for). You can then adjust the whole chain's bias (left/right or up/down) by changing the chain's head view bias.
8. Center Horizontally or Center Vertically: To create a chain of views quickly, select them all, right-click one of the views, and then select either Center Horizontally or Center Vertically, to create either a horizontal or vertical chain
9. Baseline alignment: Align the text baseline of a view to the text baseline of another view.
10. Constrain to a guideline: You can add a vertical or horizontal guideline to which you can constrain views, and the guideline will be invisible to app users. You can position the guideline within the layout based on either dp units or percent, relative to the layout's edge.
11. Adjust the constraint bias: When you add a constraint to both sides of a view (and the view size for the same dimension is either "fixed" or "wrap content"), the view becomes centered between the two constraints with a bias of 50% by default. You can adjust the bias by dragging the bias slider in the Properties window
12. Set size as a ratio: You can set the view size to a ratio such as 16:9 if at least one of the view dimensions is set to "match constraints" (0dp).

You can learn more from the official doc.

You have a JSON Lines format text file. You need to parse your file line by line:

import json

data = []
with open('file') as f:
    for line in f:
        data.append(json.loads(line))

Each line contains valid JSON, but as a whole, it is not a valid JSON value as there is no top-level list or object definition.

Note that because the file contains JSON per line, you are saved the headaches of trying to parse it all in one go or to figure out a streaming JSON parser. You can now opt to process each line separately before moving on to the next, saving memory in the process. You probably don't want to append each result to one list and then process everything if your file is really big.

If you have a file containing individual JSON objects with delimiters in-between, use How do I use the 'json' module to read in one JSON object at a time? to parse out individual objects using a buffered method.

var data={
 userName: $('#userName').val(),
 email: $('#email').val(),
 //add other properties similarly
}

and

$.ajax({
        type: "POST",
        url: "http://rt.ja.com/includes/register.php?submit=1",
        data: data

        success: function(html)
        {   
            //alert(html);
            $('#userError').html(html);
            $("#userError").html(userChar);
            $("#userError").html(userTaken);
        }
    });

You dont have to bother about anything else. jquery will handle the serialization etc. also you can append the submit query string parameter submit=1 into the data json object.

You may have to use =IF(ISNUMBER(A1),A1,1) in some situations where you are looking for number values in cell.

PostgreSQL supports schemas, which is a subset of a database: https://www.postgresql.org/docs/current/static/ddl-schemas.html

A database contains one or more named schemas, which in turn contain tables. Schemas also contain other kinds of named objects, including data types, functions, and operators. The same object name can be used in different schemas without conflict; for example, both schema1 and myschema can contain tables named mytable. Unlike databases, schemas are not rigidly separated: a user can access objects in any of the schemas in the database they are connected to, if they have privileges to do so.

Schemas are analogous to directories at the operating system level, except that schemas cannot be nested.

In my humble opinion, MySQL is not a reference database. You should never quote MySQL for an explanation. MySQL implements non-standard SQL and sometimes claims features that it does not support. For example, in MySQL, CREATE schema will only create a DATABASE. It is truely misleading users.

This kind of vocabulary is called "MySQLism" by DBAs.

You may also try this,

var arr = $('input[name="myCheckboxes[]"]').map(function(){
  return $(this).val();
}).get();

console.log(arr);

Just for completeness as nobody else has mentioned it. The third parameter to an array slice is a step. So reversing a string is as simple as:

some_string[::-1]

Or selecting alternate characters would be:

"H-e-l-l-o- -W-o-r-l-d"[::2] # outputs "Hello World"

The ability to step forwards and backwards through the string maintains consistency with being able to array slice from the start or end.

May I help you without using XML ?

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        Slice mySlice = new Slice(getApplicationContext());
        mySlice.setBackgroundColor(Color.WHITE);
        setContentView(mySlice, new LinearLayout.LayoutParams(
                LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
    }
}

Working Example :

Another absolutely simple Calculate function you may interested in ..

private Path Calculate(Point A, Point B, Point C) {
    Path Pencil = new Path();
    Pencil.moveTo(A.x, A.y);
    Pencil.lineTo(B.x, B.y);
    Pencil.lineTo(C.x, C.y);
    return Pencil;
}

AutoHotKey is perfect for this kind of tasks (keyboard automation / remapping)

Script to send "A" 100 times:

Send {A 100}

That's all

EDIT: to send the keys to an specific application:

WinActivate Word
Send {A 100}

You have to fetch that one record, it will contain the result of Count()

$result = $db->query("SELECT COUNT(*) FROM `table`");
$row = $result->fetch_row();
echo '#: ', $row[0];

ngOnInit() {
     const $ = window["$"];
     $('.flexslider').flexslider({
        animation: 'slide',
        start: function (slider) {
          $('body').removeClass('loading')
        }
     })
}

I use javadoc packaged by Allimant since I was in college.

http://www.allimant.org/javadoc/

The javadoc is in the CHM format (standard windows help format), so it's the best viewed when you're using windows.

Using Following Code You Solve thisQuestion.... If you run a file using localhost server than this problem solve by following Jsp Page Code.This Code put Between Head Tag in jsp file

<style type="text/css">
    <%@include file="css/style.css" %>
</style>
<script type="text/javascript">
    <%@include file="js/script.js" %>
</script>

This is for future developers, you can also try this. Simple too

echo preg_replace('/\D/', '', '604-619-5135');

Simply use the administrative shares to copy files between systems. It's much easier this way.

Copy-Item -Path \\serverb\c$\programs\temp\test.txt -Destination \\servera\c$\programs\temp\test.txt;

By using UNC paths instead of local filesystem paths, you help to ensure that your script is executable from any client system with access to those UNC paths. If you use local filesystem paths, then you are cornering yourself into running the script on a specific computer.

This only works when a PowerShell session runs under the user who has rights to both administrative shares.

I suggest to use regular network share on server B with read-only access to everyone and simply call (from Server A):

Copy-Item -Path "\\\ServerB\SharedPathToSourceFile" -Destination "$Env:USERPROFILE" -Force -PassThru -Verbose

For me this error occured after installing of gcloud component app-engine-python in order to integrate into pycharm. Uninstalling the module helped, even if pycharm is now not uploading to app-engine.

An alternative way is to install the Maven for Java plugin and create a maven project within Visual Studio. The steps are described in the official documentation:

1. From the Command Palette (Crtl+Shift+P), select Maven: Generate from Maven Archetype and follow the instructions, or
2. Right-click on a folder and select Generate from Maven Archetype.

There are a lot of helpful solutions out there, but there is no simplified way with extension. Here is the code to solve the issue with an extension:

extension UIImage {

    var getWidth: CGFloat {
        get {
            let width = self.size.width
            return width
        }
    }

    var getHeight: CGFloat {
        get {
            let height = self.size.height
            return height
        }
    }
}

If you want a solution that also works in /bin/sh try

first_arg="$1"
shift
echo First argument: "$first_arg"
echo Remaining arguments: "$@"

shift [n] shifts the positional parameters n times. A shift sets the value of $1 to the value of $2, the value of $2 to the value of $3, and so on, decreasing the value of $# by one.

This expands on @Reigel's answer. It will return an answer for horizontal or vertical scrollbars.

(function($) {
    $.fn.hasScrollBar = function() {
        var e = this.get(0);
        return {
            vertical: e.scrollHeight > e.clientHeight,
            horizontal: e.scrollWidth > e.clientWidth
        };
    }
})(jQuery);

Example:

element.hasScrollBar()             // Returns { vertical: true/false, horizontal: true/false }
element.hasScrollBar().vertical    // Returns true/false
element.hasScrollBar().horizontal  // Returns true/false

EDIT : It is not bleeding edge anymore : http://blog.docker.com/2016/02/docker-1-10/

Original Answer
I battled with it the whole night. If you're not afraid of bleeding edge, the latest version of Docker engine and Docker compose both implement libnetwork.

With the right config file (that need to be put in version 2), you will create services that will all see each other. And, bonus, you can scale them with docker-compose as well (you can scale any service you want that doesn't bind port on the host)

Here is an example file

version: "2"
services:
  router:
    build: services/router/
    ports:
      - "8080:8080"
  auth:
    build: services/auth/
  todo:
    build: services/todo/
  data:
    build: services/data/

And the reference for this new version of compose file: https://github.com/docker/compose/blob/1.6.0-rc1/docs/networking.md

I had trouble with the existing answers when using multidimensional arrays. This solution works for me.

if (is_array($array)) {
    foreach ($array as $key => $val) {
        $array[$key] = trim($val);
    }
}
