You guys copied the wrong code.

Go into the "/build" folder and grab the jquery.datetimepicker.full.js or jquery.datetimepicker.full.min.js if you want the minified version. It should fix it! :)

I simply do this:

    UIWebView *webView = [[[UIWebView alloc] init] autorelease];

    NSURL *url = [[NSBundle mainBundle] URLForResource:@"index" withExtension:@"html"];
    NSURLRequest* request = [NSURLRequest requestWithURL:url];
    [webView loadRequest:request];

Where "index.html" relatively references images, CSS, javascript, etc.

On Mac to see the help: ?/ then you will see Keyboard shortcuts.

Rotate right: ?? , Rotate left: ??

lst *= 0

has the same effect as

lst[:] = []

It's a little simpler and maybe easier to remember. Other than that there's not much to say

The efficiency seems to be about the same

A major practical difference is its use:

in security scenario where we always needed a new session, we should use request.getSession(true).

request.getSession(false): will return null if no session found.

I haven't tested this but could you use a set of pairs of iterators instead? Each iterator pair would represent the begin and end iterator of the sequence vector. E.g.:

typedef std::vector<int> Seq;
typedef std::pair<Seq::const_iterator, Seq::const_iterator> SeqRange;

bool operator< (const SeqRange& lhs, const SeqRange& rhs)
{
    Seq::const_iterator lhsNext = lhs.first;
    Seq::const_iterator rhsNext = rhs.first;

    while (lhsNext != lhs.second && rhsNext != rhs.second)
        if (*lhsNext < *rhsNext)
            return true;
        else if (*lhsNext > *rhsNext)
            return false;

    return false;
}

typedef std::set<SeqRange, std::less<SeqRange> > SeqSet;

Seq sequences;

void test (const SeqSet& seqSet, const SeqRange& seq)
{
    bool find = seqSet.find (seq) != seqSet.end ();
    bool find2 = seqSet.find (SeqRange (seq.first + 1, seq.second)) != seqSet.end ();
}

Obviously the vectors have to be held elsewhere as before. Also if a sequence vector is modified then its entry in the set would have to be removed and re-added as the iterators may have changed.

Could you not have simply added:

align-items:center;

to a new class in your row div. Essentially:

<div class="row align_center">

.align_center { align-items:center; }

def recursive_copy_files(source_path, destination_path, override=False):
    """
    Recursive copies files from source  to destination directory.
    :param source_path: source directory
    :param destination_path: destination directory
    :param override if True all files will be overridden otherwise skip if file exist
    :return: count of copied files
    """
    files_count = 0
    if not os.path.exists(destination_path):
        os.mkdir(destination_path)
    items = glob.glob(source_path + '/*')
    for item in items:
        if os.path.isdir(item):
            path = os.path.join(destination_path, item.split('/')[-1])
            files_count += recursive_copy_files(source_path=item, destination_path=path, override=override)
        else:
            file = os.path.join(destination_path, item.split('/')[-1])
            if not os.path.exists(file) or override:
                shutil.copyfile(item, file)
                files_count += 1
    return files_count

As jt said, NIO is the best (and correct) solution. If you really are stuck with an InputStream though, you could either

1. Spawn a thread who's exclusive job is to read from the InputStream and put the result into a buffer which can be read from your original thread without blocking. This should work well if you only ever have one instance of the stream. Otherwise you may be able to kill the thread using the deprecated methods in the Thread class, though this may cause resource leaks.

2. Rely on isAvailable to indicate data that can be read without blocking. However in some cases (such as with Sockets) it can take a potentially blocking read for isAvailable to report something other than 0.

I finally found the way to do what the OP wanted. It's as simple as:

git log --graph [branchname]

The command will display all commits that are reachable from the provided branch in the format of graph. But, you can easily filter all commits on that branch by looking at the commits graph whose * is the first character in the commit line.

For example, let's look at the excerpt of git log --graph master on cakephp GitHub repo below:

D:\Web Folder\cakephp>git log --graph master

I had the same issue on Win x86/64 because my custom Python3.7 installation did not include Tcl packages, so just modify or re-install your python

https://www.python.org/downloads/release/python-370/

For everyone who looks example that works with Swift 2.2, Abizern code with modern do try catch handle of error

func databaseURL() -> NSURL? {

    let fileManager = NSFileManager.defaultManager()

    let urls = fileManager.URLsForDirectory(.DocumentDirectory, inDomains: .UserDomainMask)

    if let documentDirectory:NSURL = urls.first { // No use of as? NSURL because let urls returns array of NSURL
        // This is where the database should be in the documents directory
        let finalDatabaseURL = documentDirectory.URLByAppendingPathComponent("OurFile.plist")

        if finalDatabaseURL.checkResourceIsReachableAndReturnError(nil) {
            // The file already exists, so just return the URL
            return finalDatabaseURL
        } else {
            // Copy the initial file from the application bundle to the documents directory
            if let bundleURL = NSBundle.mainBundle().URLForResource("OurFile", withExtension: "plist") {

                do {
                    try fileManager.copyItemAtURL(bundleURL, toURL: finalDatabaseURL)
                } catch let error as NSError  {// Handle the error
                    print("Couldn't copy file to final location! Error:\(error.localisedDescription)")
                }

            } else {
                print("Couldn't find initial database in the bundle!")
            }
        }
    } else {
        print("Couldn't get documents directory!")
    }

    return nil
}

Update I've missed that new swift 2.0 have guard(Ruby unless analog), so with guard it is much shorter and more readable

func databaseURL() -> NSURL? {

let fileManager = NSFileManager.defaultManager()
let urls = fileManager.URLsForDirectory(.DocumentDirectory, inDomains: .UserDomainMask)

// If array of path is empty the document folder not found
guard urls.count != 0 else {
    return nil
}

let finalDatabaseURL = urls.first!.URLByAppendingPathComponent("OurFile.plist")
// Check if file reachable, and if reacheble just return path
guard finalDatabaseURL.checkResourceIsReachableAndReturnError(nil) else {
    // Check if file is exists in bundle folder
    if let bundleURL = NSBundle.mainBundle().URLForResource("OurFile", withExtension: "plist") {
        // if exist we will copy it
        do {
            try fileManager.copyItemAtURL(bundleURL, toURL: finalDatabaseURL)
        } catch let error as NSError { // Handle the error
            print("File copy failed! Error:\(error.localizedDescription)")
        }
    } else {
        print("Our file not exist in bundle folder")
        return nil
    }
    return finalDatabaseURL
}
return finalDatabaseURL 
}

If you do not need the recording and playback functionality in your app, using off-the-shelf streaming app and player is a reasonable choice.

If you do need them to be in your app, however, you will have to look into MediaRecorder API (for the server/camera app) and MediaPlayer (for client/player app).

Quick sample code for the server:

// this is your network socket
ParcelFileDescriptor pfd = ParcelFileDescriptor.fromSocket(socket);
mCamera = getCameraInstance();
mMediaRecorder = new MediaRecorder();
mCamera.unlock();
mMediaRecorder.setCamera(mCamera);
mMediaRecorder.setAudioSource(MediaRecorder.AudioSource.CAMCORDER);
mMediaRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
// this is the unofficially supported MPEG2TS format, suitable for streaming (Android 3.0+)
mMediaRecorder.setOutputFormat(8);
mMediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.DEFAULT);
mMediaRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.DEFAULT);
mediaRecorder.setOutputFile(pfd.getFileDescriptor());
mMediaRecorder.setPreviewDisplay(mPreview.getHolder().getSurface());
mMediaRecorder.prepare();
mMediaRecorder.start();

On the player side it is a bit tricky, you could try this:

// this is your network socket, connected to the server
ParcelFileDescriptor pfd = ParcelFileDescriptor.fromSocket(socket);
mMediaPlayer = new MediaPlayer();
mMediaPlayer.setDataSource(pfd.getFileDescriptor());
mMediaPlayer.prepare();
mMediaPlayer.start();

Unfortunately mediaplayer tends to not like this, so you have a couple of options: either (a) save data from socket to file and (after you have a bit of data) play with mediaplayer from file, or (b) make a tiny http proxy that runs locally and can accept mediaplayer's GET request, reply with HTTP headers, and then copy data from the remote server to it. For (a) you would create the mediaplayer with a file path or file url, for (b) give it a http url pointing to your proxy.

You need to add tabs plugin to your code

<script type="text/javascript" src="assets/twitterbootstrap/js/bootstrap-tab.js"></script>

Well, it didn't work. I made some tests and it started working when:

1. moved (updated to 1.7) jQuery script to <head> section
2. added data-toggle="tab" to links and id for <ul> tab element
3. changed $(".tabs").tabs(); to $("#tabs").tab();
4. and some other things that shouldn't matter

According to this post this error message means:

Heap size is larger than your computer's physical memory.

Edit: Heap is not the only memory that is reserved, I suppose. At least there are other JVM settings like PermGenSpace that ask for the memory. With heap size 128M and a PermGenSpace of 64M you already fill the space available.

Why not downsize other memory settings to free up space for the heap?

As some people have mentioned, Javascript is the way to go. Bear in mind that the "validation" here is only by file extension, it won't validate that the file is a real excel spreadsheet!

This was happening to me specifically on PHPMyAdmin. So to more specifically answer this, I did the following:

In File:

C:\ampps\phpMyAdmin\libraries\DisplayResults.class.php

I changed this:

// Move to the next page or to the last one
$endpos = $_SESSION['tmpval']['pos']
    + $_SESSION['tmpval']['max_rows'];

To this:

$endpos = 0;
if (!empty($_SESSION['tmpval']['pos']) && is_numeric($_SESSION['tmpval']['pos'])) {
    $endpos += $_SESSION['tmpval']['pos'];
}
if (!empty($_SESSION['tmpval']['max_rows']) && is_numeric($_SESSION['tmpval']['max_rows'])) {
    $endpos += $_SESSION['tmpval']['max_rows'];
}

Hope that save's someone some trouble...

The number of parameters is 7850 because with every hidden unit you have 784 input weights and one weight of connection with bias. This means that every hidden unit gives you 785 parameters. You have 10 units so it sums up to 7850.

The role of this additional bias term is really important. It significantly increases the capacity of your model. You can read details e.g. here Role of Bias in Neural Networks.

This code would create a select list dynamically. First I create an array with the car names. Second, I create a select element dynamically and assign it to a variable "sEle" and append it to the body of the html document. Then I use a for loop to loop through the array. Third, I dynamically create the option element and assign it to a variable "oEle". Using an if statement, I assign the attributes 'disabled' and 'selected' to the first option element [0] so that it would be selected always and is disabled. I then create a text node array "oTxt" to append the array names and then append the text node to the option element which is later appended to the select element.

var array = ['Select Car', 'Volvo', 'Saab', 'Mervedes', 'Audi'];_x000D_
_x000D_
var sEle = document.createElement('select');_x000D_
document.getElementsByTagName('body')[0].appendChild(sEle);_x000D_
_x000D_
for (var i = 0; i < array.length; ++i) {_x000D_
  var oEle = document.createElement('option');_x000D_
_x000D_
  if (i == 0) {_x000D_
    oEle.setAttribute('disabled', 'disabled');_x000D_
    oEle.setAttribute('selected', 'selected');_x000D_
  } // end of if loop_x000D_
_x000D_
  var oTxt = document.createTextNode(array[i]);_x000D_
  oEle.appendChild(oTxt);_x000D_
_x000D_
  document.getElementsByTagName('select')[0].appendChild(oEle);_x000D_
} // end of for loop

You can actually define your template class inside a .template file rather than a .cpp file. Whoever is saying you can only define it inside a header file is wrong. This is something that works all the way back to c++ 98.

Don't forget to have your compiler treat your .template file as a c++ file to keep the intelli sense.

Here is an example of this for a dynamic array class.

#ifndef dynarray_h
#define dynarray_h

#include <iostream>

template <class T>
class DynArray{
    int capacity_;
    int size_;
    T* data;
public:
    explicit DynArray(int size = 0, int capacity=2);
    DynArray(const DynArray& d1);
    ~DynArray();
    T& operator[]( const int index);
    void operator=(const DynArray<T>& d1);
    int size();

    int capacity();
    void clear();

    void push_back(int n);

    void pop_back();
    T& at(const int n);
    T& back();
    T& front();
};

#include "dynarray.template" // this is how you get the header file

#endif

Now inside you .template file you define your functions just how you normally would.

template <class T>
DynArray<T>::DynArray(int size, int capacity){
    if (capacity >= size){
        this->size_ = size;
        this->capacity_ = capacity;
        data = new T[capacity];
    }
    //    for (int i = 0; i < size; ++i) {
    //        data[i] = 0;
    //    }
}

template <class T>
DynArray<T>::DynArray(const DynArray& d1){
    //clear();
    //delete [] data;
    std::cout << "copy" << std::endl;
    this->size_ = d1.size_;
    this->capacity_ = d1.capacity_;
    data = new T[capacity()];
    for(int i = 0; i < size(); ++i){
        data[i] = d1.data[i];
    }
}

template <class T>
DynArray<T>::~DynArray(){
    delete [] data;
}

template <class T>
T& DynArray<T>::operator[]( const int index){
    return at(index);
}

template <class T>
void DynArray<T>::operator=(const DynArray<T>& d1){
    if (this->size() > 0) {
        clear();
    }
    std::cout << "assign" << std::endl;
    this->size_ = d1.size_;
    this->capacity_ = d1.capacity_;
    data = new T[capacity()];
    for(int i = 0; i < size(); ++i){
        data[i] = d1.data[i];
    }

    //delete [] d1.data;
}

template <class T>
int DynArray<T>::size(){
    return size_;
}

template <class T>
int DynArray<T>::capacity(){
    return capacity_;
}

template <class T>
void DynArray<T>::clear(){
    for( int i = 0; i < size(); ++i){
        data[i] = 0;
    }
    size_ = 0;
    capacity_ = 2;
}

template <class T>
void DynArray<T>::push_back(int n){
    if (size() >= capacity()) {
        std::cout << "grow" << std::endl;
        //redo the array
        T* copy = new T[capacity_ + 40];
        for (int i = 0; i < size(); ++i) {
            copy[i] = data[i];
        }

        delete [] data;
        data = new T[ capacity_ * 2];
        for (int i = 0; i < capacity() * 2; ++i) {
            data[i] = copy[i];
        }
        delete [] copy;
        capacity_ *= 2;
    }
    data[size()] = n;
    ++size_;
}

template <class T>
void DynArray<T>::pop_back(){
    data[size()-1] = 0;
    --size_;
}

template <class T>
T& DynArray<T>::at(const int n){
    if (n >= size()) {
        throw std::runtime_error("invalid index");
    }
    return data[n];
}

template <class T>
T& DynArray<T>::back(){
    if (size() == 0) {
        throw std::runtime_error("vector is empty");
    }
    return data[size()-1];
}

template <class T>
T& DynArray<T>::front(){
    if (size() == 0) {
        throw std::runtime_error("vector is empty");
    }

I'm not a programmer, but I have been a human factors engineer. I feel a programming language should be easy to learn, understand and use, and this requires that it have a simple and consistent linguistic structure. Although all the languages is symbolic and thus, at its core, arbitrary, there are conventions and following them makes the language easier to learn and use.

There are a vast number of functions in C++ and other languages written as function(parameter), a syntax that was originally used for functional relationships in mathematics in the pre-computer era. printf() follows this syntax and if the writers of C++ wanted to create any logically different method for reading and writing files they could have simply created a different function using a similar syntax.

In Python we of course can print using the also fairly standard object.method syntax, i.e. variablename.print, since variables are objects, but in C++ they are not.

I'm not fond of the cout syntax because the << operator does not follow any rules. It is a method or function, i.e. it takes a parameter and does something to it. However it is written as though it were a mathematical comparison operator. This is a poor approach from a human factors standpoint.

A bit late, but this could also be useful. There is an IE filter, for IE 5.5+, which you can apply:

filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(
src='images/logo.gif',
sizingMethod='scale');

-ms-filter: "progid:DXImageTransform.Microsoft.AlphaImageLoader(
src='images/logo.gif',
sizingMethod='scale')";

However, this scales the entire image to fit in the allocated area, so if you're using a sprite, this may cause issues.

Specification: AlphaImageLoader Filter @microsoft

I hope this will help.

It's a permission problem.

When you run the console app, that app runs with your credentials, e.g. as "you".

The WCF service runs where? In IIS? Most likely, it runs under a separate account, which is not permissioned to query Active Directory.

You can either try to get the WCF impersonation thingie working, so that your own credentials get passed on, or you can specify a username/password on creating your DirectoryEntry:

DirectoryEntry directoryEntry = 
    new DirectoryEntry("LDAP://someserver.contoso.com/DC=contoso,DC=com", 
                       userName, password);

OK, so it might not be the credentials after all (that's usually the case in over 80% of the cases I see).

What about changing your code a little bit?

DirectorySearcher directorySearcher = new DirectorySearcher(directoryEntry);
directorySearcher.Filter = string.Format("(&(objectClass=user)(objectCategory=user) (sAMAccountName={0}))", username);

directorySearcher.PropertiesToLoad.Add("msRTCSIP-PrimaryUserAddress");

var result = directorySearcher.FindOne();

if(result != null)
{
   if(result.Properties["msRTCSIP-PrimaryUserAddress"] != null)
   {
      var resultValue = result.Properties["msRTCSIP-PrimaryUserAddress"][0];
   }
}

My idea is: why not tell the DirectorySearcher right off the bat what attribute you're interested in? Then you don't need to do another extra step to get the full DirectoryEntry from the search result (should be faster), and since you told the directory searcher to find that property, it's certainly going to be loaded in the search result - so unless it's null (no value set), then you should be able to retrieve it easily.

Here's a reusable way of doing it (it's typescript but you can adapt it to js):

export function waitFor<T>(signal: Observable<any>) {
    return (source: Observable<T>) =>
        new Observable<T>(observer =>
            signal.pipe(first())
                .subscribe(_ =>
                    source.subscribe(observer)
                )
        );
}

and you can use it like any operator:

var two = someOtherObservable.pipe(waitFor(one), take(1));

It's basically an operator that defers the subscribe on the source observable until the signal observable emits the first event.

First you need to allocate an array of the combined length, then use arraycopy to fill it from both sources.

byte[] ciphertext = blah;
byte[] mac = blah;
byte[] out = new byte[ciphertext.length + mac.length];


System.arraycopy(ciphertext, 0, out, 0, ciphertext.length);
System.arraycopy(mac, 0, out, ciphertext.length, mac.length);

Simple code please check

SELECT * FROM table_name WHERE created <= (NOW() - INTERVAL 1 MONTH)

When checking a number value you can use the VisualBasic.IsNumeric function.

The package collapse has it built in: %!in%.

wmic bios get serialnumber     

if run from a command line (start-run should also do the trick) prints out on screen the Serial Number of the product,
(for example in a toshiba laptop it would print out the serial number of the laptop.
with this serial number you can then identify your laptop model if you need ,from the makers service website-usually..:):)

I had to do exactly that.:):)

Check that userInteractionEnabled is YES on the UIImageView. Then you can add a gesture recognizer.

imageView.userInteractionEnabled = YES;
UIPinchGestureRecognizer *pgr = [[UIPinchGestureRecognizer alloc] 
    initWithTarget:self action:@selector(handlePinch:)];
pgr.delegate = self;
[imageView addGestureRecognizer:pgr];
[pgr release];
:
:
- (void)handlePinch:(UIPinchGestureRecognizer *)pinchGestureRecognizer
{
  //handle pinch...
}

How about the following 3 statements?

-- change to your schema

ALTER SESSION SET CURRENT_SCHEMA=yourSchemaName;

-- check current schema

SELECT SYS_CONTEXT('USERENV','CURRENT_SCHEMA') FROM DUAL;

-- generate drop table statements

SELECT 'drop table ', table_name, 'cascade constraints;' FROM ALL_TABLES WHERE OWNER = 'yourSchemaName';

COPY the RESULT and PASTE and RUN.

The JVM and the underlying OS have considerable freedom when scheduling things. The fact that you get all the way to "Waiting for threads to finish" before you see the output from individual threads may simply mean that thread start-up takes a bit longer (i.e. it takes some time between the moment when a thread becomes "alive" and when the run() method actually starts executing). You could conceivably see thread output sooner but it's not guaranteed either way.

As for join(), it only guarantees that whatever is after it will only happen once the thread you are joining is done. So when you have three join() calls in a row it doesn't mean the threads should end in a particular order. It simply means that you will wait for ob1 first. Once ob1 finishes, ob2 and ob3 may be still running or they may already be finished. If they are finished, your other join() calls will return immediately.

synchronized is used specifically when multiple threads access the same object and make changes to it. A synchronized block is guaranteed never to be executed by two threads simultaneously - i.e. the thread that executes it has the synchronized object all to itself.

Seriously, question exists five years and no nice facade?

function is_dir(path) {
    try {
        var stat = fs.lstatSync(path);
        return stat.isDirectory();
    } catch (e) {
        // lstatSync throws an error if path doesn't exist
        return false;
    }
}

You can combine the check and cast into one statement:

let touch = object.anyObject() as UITouch
if let picker = touch.view as? UIPickerView {
    ...
}

Then you can use picker within the if block.

The accepted answer wasn't working for me when trying to parse the registry for uninstall strings, and execute them. Turns out I didn't need the call to Invoke-Expression after all.

I finally came across this nice template for seeing how to execute uninstall strings:

$path = 'HKLM:\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall'
$app = 'MyApp'
$apps= @{}
Get-ChildItem $path | 
    Where-Object -FilterScript {$_.getvalue('DisplayName') -like $app} | 
    ForEach-Object -process {$apps.Set_Item(
        $_.getvalue('UninstallString'),
        $_.getvalue('DisplayName'))
    }

foreach ($uninstall_string in $apps.GetEnumerator()) {
    $uninstall_app, $uninstall_arg = $uninstall_string.name.split(' ')
    & $uninstall_app $uninstall_arg
}

This works for me, namely because $app is an in house application that I know will only have two arguments. For more complex uninstall strings you may want to use the join operator. Also, I just used a hash-map, but really, you'd probably want to use an array.

Also, if you do have multiple versions of the same application installed, this uninstaller will cycle through them all at once, which confuses MsiExec.exe, so there's that too.

Here is my answer when you want to animate it and start fading it out after couple of seconds. I used opacity because first of all i didn't want to fade it out completely, second, it does not go back and force after many scrolls.

$(window).scroll(function () {
    var elem = $('div');
    setTimeout(function() {
        elem.css({"opacity":"0.2","transition":"2s"});
    },4000);            
    elem.css({"opacity":"1","transition":"1s"});    
});

I my case I found out the void for the main function declaration was missing.

I was previously using Visual Studio in Windows and this was never a problem, so I thought I might leave it out now too.

Assuming the expectation is just going to be two windows popping up (one of the parent and one for the popup) then just wait for two windows to come up, find the other window handle and switch to it.

WebElement link = // element that will showModalDialog()

// Click on the link, but don't wait for the document to finish
final JavascriptExecutor executor = (JavascriptExecutor) driver;
executor.executeScript(
    "var el=arguments[0]; setTimeout(function() { el.click(); }, 100);",
  link);

// wait for there to be two windows and choose the one that is 
// not the original window
final String parentWindowHandle = driver.getWindowHandle();
new WebDriverWait(driver, 60, 1000)
    .until(new Function<WebDriver, Boolean>() {
    @Override
    public Boolean apply(final WebDriver driver) {
        final String[] windowHandles =
            driver.getWindowHandles().toArray(new String[0]);
        if (windowHandles.length != 2) {
            return false;
        }
        if (windowHandles[0].equals(parentWindowHandle)) {
            driver.switchTo().window(windowHandles[1]);
        } else {
            driver.switchTo().window(windowHandles[0]);
        }
        return true;
    }
});

You can add + behind the variable and it will force it to be an integer

var dots = 5
    function increase(){
        dots = +dots + 5;
    }

Yet another option is to have, in Ticket, one column specifying the owning entity type (User or Group), second column with referenced User or Group id and NOT to use Foreign Keys but instead rely on a Trigger to enforce referential integrity.

Two advantages I see here over Nathan's excellent model (above):

• More immediate clarity and simplicity.
• Simpler queries to write.

I would also suggest deselecting an item after it has been clicked and use the MouseDoubleClick event

private void listBox_MouseDoubleClick(object sender, MouseButtonEventArgs e)
{
    try {
        //Do your stuff here
        listBox.SelectedItem = null;
        listBox.SelectedIndex = -1;
    } catch (Exception ex) {
        System.Diagnostics.Debug.WriteLine(ex.Message);
    }
}

I use this custom binding (based on this fiddle by RP Niemeyer, see his answer to this question), which makes sure the numeric value is properly converted from string to number (as suggested by the solution of Michael Best):

Javascript:

ko.bindingHandlers.valueAsNumber = {
    init: function (element, valueAccessor, allBindingsAccessor) {
        var observable = valueAccessor(),
            interceptor = ko.computed({
                read: function () {
                    var val = ko.utils.unwrapObservable(observable);
                    return (observable() ? observable().toString() : observable());
                },
                write: function (newValue) {
                    observable(newValue ? parseInt(newValue, 10) : newValue);
                },
                owner: this
            });
        ko.applyBindingsToNode(element, { value: interceptor });
    }
};

Example HTML:

<select data-bind="valueAsNumber: level, event:{ change: $parent.permissionChanged }">
    <option value="0"></option>
    <option value="1">R</option>
    <option value="2">RW</option>
</select>

the most effective method is to use android-async-http

You can use this code to upload a file:

// gather your request parameters
File myFile = new File("/path/to/file.png");
RequestParams params = new RequestParams();
try {
    params.put("profile_picture", myFile);
} catch(FileNotFoundException e) {}

// send request
AsyncHttpClient client = new AsyncHttpClient();
client.post(url, params, new AsyncHttpResponseHandler() {
    @Override
    public void onSuccess(int statusCode, Header[] headers, byte[] bytes) {
        // handle success response
    }

    @Override
    public void onFailure(int statusCode, Header[] headers, byte[] bytes, Throwable throwable) {
        // handle failure response
    }
});

Note that you can put this code directly into your main Activity, no need to create a background Task explicitly. AsyncHttp will take care of that for you!

here is the sample code to draw image on canvas-

$("#selectedImage").change(function(e) {

var URL = window.URL;
var url = URL.createObjectURL(e.target.files[0]);
img.src = url;

img.onload = function() {
    var canvas = document.getElementById("myCanvas");
    var ctx = canvas.getContext("2d");        

    ctx.clearRect(0, 0, canvas.width, canvas.height);
    ctx.drawImage(img, 0, 0, 500, 500);
}});

In the above code selectedImage is an input control which can be used to browse image on system. For more details of sample code to draw image on canvas while maintaining the aspect ratio:

As you can see, the AND operator drops every row in which at least one value equals -1. On the other hand, the OR operator requires both values to be equal to -1 to drop them.

That's right. Remember that you're writing the condition in terms of what you want to keep, not in terms of what you want to drop. For df1:

df1 = df[(df.a != -1) & (df.b != -1)]

You're saying "keep the rows in which df.a isn't -1 and df.b isn't -1", which is the same as dropping every row in which at least one value is -1.

For df2:

df2 = df[(df.a != -1) | (df.b != -1)]

You're saying "keep the rows in which either df.a or df.b is not -1", which is the same as dropping rows where both values are -1.

PS: chained access like df['a'][1] = -1 can get you into trouble. It's better to get into the habit of using .loc and .iloc.

@NotNull is a JSR 303 Bean Validation annotation. It has nothing to do with database constraints itself. As Hibernate is the reference implementation of JSR 303, however, it intelligently picks up on these constraints and translates them into database constraints for you, so you get two for the price of one. @Column(nullable = false) is the JPA way of declaring a column to be not-null. I.e. the former is intended for validation and the latter for indicating database schema details. You're just getting some extra (and welcome!) help from Hibernate on the validation annotations.

I ended up with this because other answers either lose resolution or work with UIImageView, not UIImage, or contain unnecessary actions:

Swift 3

extension UIImage {
    
    public func mask(with color: UIColor) -> UIImage {
        
        UIGraphicsBeginImageContextWithOptions(self.size, false, self.scale)
        let context = UIGraphicsGetCurrentContext()!
        
        let rect = CGRect(origin: CGPoint.zero, size: size)
        
        color.setFill()
        self.draw(in: rect)
        
        context.setBlendMode(.sourceIn)
        context.fill(rect)
        
        let resultImage = UIGraphicsGetImageFromCurrentImageContext()!
        UIGraphicsEndImageContext()
        return resultImage
    }
    
}

Here goes what O'reilly Enterprise JavaBeans, 3.0 says

JDBC has special types for these very large objects. The java.sql.Blob type represents binary data, and java.sql.Clob represents character data.

Here goes PostgreSQLDialect source code

public PostgreSQLDialect() {
    super();
    ...
    registerColumnType(Types.VARBINARY, "bytea");
    /**
      * Notice it maps java.sql.Types.BLOB as oid
      */
    registerColumnType(Types.BLOB, "oid");
}

So what you can do

Override PostgreSQLDialect as follows

public class CustomPostgreSQLDialect extends PostgreSQLDialect {

    public CustomPostgreSQLDialect() {
        super();

        registerColumnType(Types.BLOB, "bytea");
    }
}

Now just define your custom dialect

<property name="hibernate.dialect" value="br.com.ar.dialect.CustomPostgreSQLDialect"/>

And use your portable JPA @Lob annotation

@Lob
public byte[] getValueBuffer() {

UPDATE

Here has been extracted here

I have an application running in hibernate 3.3.2 and the applications works fine, with all blob fields using oid (byte[] in java)

...

Migrating to hibernate 3.5 all blob fields not work anymore, and the server log shows: ERROR org.hibernate.util.JDBCExceptionReporter - ERROR: column is of type oid but expression is of type bytea

which can be explained here

This generaly is not bug in PG JDBC, but change of default implementation of Hibernate in 3.5 version. In my situation setting compatible property on connection did not helped.

...

Much more this what I saw in 3.5 - beta 2, and i do not know if this was fixed is Hibernate - without @Type annotation - will auto-create column of type oid, but will try to read this as bytea

Interesting is because when he maps Types.BOLB as bytea (See CustomPostgreSQLDialect) He get

Could not execute JDBC batch update

when inserting or updating

This is solved easily by removing you previous app from your device. And start to reinstall again. This works fine for me.

Technically speaking, the C standard only guarantees that sizeof(char) == 1, and the rest is up to the implementation. But on modern x86 architectures (e.g. Intel/AMD chips) it's fairly predictable.

You've probably heard processors described as being 16-bit, 32-bit, 64-bit, etc. This usually means that the processor uses N-bits for integers. Since pointers store memory addresses, and memory addresses are integers, this effectively tells you how many bits are going to be used for pointers. sizeof is usually measured in bytes, so code compiled for 32-bit processors will report the size of pointers to be 4 (32 bits / 8 bits per byte), and code for 64-bit processors will report the size of pointers to be 8 (64 bits / 8 bits per byte). This is where the limitation of 4GB of RAM for 32-bit processors comes from -- if each memory address corresponds to a byte, to address more memory you need integers larger than 32-bits.

I know its pretty old but I just encounter the problem and there is what I saw in the SQL doc :

[For best results when using BETWEEN with date or time values,] use CAST() to explicitly convert the values to the desired data type. Examples: If you compare a DATETIME to two DATE values, convert the DATE values to DATETIME values. If you use a string constant such as '2001-1-1' in a comparison to a DATE, cast the string to a DATE.

I assume it's better to use STR_TO_DATE since they took the time to make a function just for that and also the fact that i found this in the BETWEEN doc...

I had a similar problem . For this you can use a Hashmap which takes "string" and "object" as shown in code below:

/** stores the image database icons */
public static int[] imageIconDatabase = { R.drawable.ball,
        R.drawable.catmouse, R.drawable.cube, R.drawable.fresh,
        R.drawable.guitar, R.drawable.orange, R.drawable.teapot,
        R.drawable.india, R.drawable.thailand, R.drawable.netherlands,
        R.drawable.srilanka, R.drawable.pakistan,

};
private void initializeImageList() {
    // TODO Auto-generated method stub
    for (int i = 0; i < imageIconDatabase.length; i++) {
        map = new HashMap<String, Object>();

        map.put("Name", imageNameDatabase[i]);
        map.put("Icon", imageIconDatabase[i]);
    }

}

Maybe you can wrap the PowerShell invocation in a .bat file like so:

rem ps.bat
@echo off
powershell.exe -command "%*"

If you then placed this file under a folder in your PATH, you could call PowerShell scripts like this:

ps foo 1 2 3

Quoting can get a little messy, though:

ps write-host """hello from cmd!""" -foregroundcolor green

$date = new DateTime("2017-05-18"); // For today/now, don't pass an arg.
$date->modify("-1 day");
echo $date->format("Y-m-d H:i:s");

Using DateTime has significantly reduced the amount of headaches endured whilst manipulating dates.

you can filter the waypoints by passing the user to the form init

class waypointForm(forms.Form):
    def __init__(self, user, *args, **kwargs):
        super(waypointForm, self).__init__(*args, **kwargs)
        self.fields['waypoints'] = forms.ChoiceField(
            choices=[(o.id, str(o)) for o in Waypoint.objects.filter(user=user)]
        )

from your view while initiating the form pass the user

form = waypointForm(user)

in case of model form

class waypointForm(forms.ModelForm):
    def __init__(self, user, *args, **kwargs):
        super(waypointForm, self).__init__(*args, **kwargs)
        self.fields['waypoints'] = forms.ModelChoiceField(
            queryset=Waypoint.objects.filter(user=user)
        )

    class Meta:
        model = Waypoint

NuPKG files are just zip files, so anything that can process a zip file should be able to process a nupkg file, i.e, 7zip.

In ES6, it is good to use for - of loop. You can get index in for of like this

for (let [index, val] of array.entries()) {
        // your code goes here    
}

Note that Array.entries() returns an iterator, which is what allows it to work in the for-of loop; don't confuse this with Object.entries(), which returns an array of key-value pairs.

Fstrings

If you are using Python 3.6+ you can make use of the new so called f-strings which stands for formatted strings and it can be used by adding the character f at the beginning of a string to identify this as an f-string.

price = 123
name = "Jerry"
print(f"{name}!!, {price} is much, isn't {price} a lot? {name}!")
>Jerry!!, 123 is much, isn't 123 a lot? Jerry!

The main benefits of using f-strings is that they are more readable, can be faster, and offer better performance:

Source Pandas for Everyone: Python Data Analysis, By Daniel Y. Chen

Benchmarks

No doubt that the new f-strings are more readable, as you don't have to remap the strings, but is it faster though as stated in the aformentioned quote?

price = 123
name = "Jerry"

def new():
    x = f"{name}!!, {price} is much, isn't {price} a lot? {name}!"


def old():
    x = "{1}!!, {0} is much, isn't {0} a lot? {1}!".format(price, name)

import timeit
print(timeit.timeit('new()', setup='from __main__ import new', number=10**7))
print(timeit.timeit('old()', setup='from __main__ import old', number=10**7))
> 3.8741058271543776  #new
> 5.861819514350163   #old

Running 10 Million test's it seems that the new f-strings are actually faster in mapping.

Per this github comment, one can disable urllib3 request warnings via requests in a 1-liner:

requests.packages.urllib3.disable_warnings()

This will suppress all warnings though, not just InsecureRequest (ie it will also suppress InsecurePlatform etc). In cases where we just want stuff to work, I find the conciseness handy.

This will work for you in Python;

# Call JIRA API with HTTPBasicAuth
import json
import requests
from requests.auth import HTTPBasicAuth

JIRA_EMAIL = "****"
JIRA_TOKEN = "****"
BASE_URL = "https://****.atlassian.net"
API_URL = "/rest/api/3/serverInfo"

API_URL = BASE_URL+API_URL

BASIC_AUTH = HTTPBasicAuth(JIRA_EMAIL, JIRA_TOKEN)
HEADERS = {'Content-Type' : 'application/json;charset=iso-8859-1'}

response = requests.get(
    API_URL,
    headers=HEADERS,
    auth=BASIC_AUTH
)

print(json.dumps(json.loads(response.text), sort_keys=True, indent=4, separators=(",", ": ")))

All of these answers appear too bulky and long. Use requests to shorten the code, e.g.:

import requests, zipfile, io
r = requests.get(zip_file_url)
z = zipfile.ZipFile(io.BytesIO(r.content))
z.extractall("/path/to/directory")

It is a unary operator (taking a single argument) that is borrowed from C, where all data types are just different ways of interpreting bytes. It is the "invert" or "complement" operation, in which all the bits of the input data are reversed.

In Python, for integers, the bits of the twos-complement representation of the integer are reversed (as in b <- b XOR 1 for each individual bit), and the result interpreted again as a twos-complement integer. So for integers, ~x is equivalent to (-x) - 1.

The reified form of the ~ operator is provided as operator.invert. To support this operator in your own class, give it an __invert__(self) method.

>>> import operator
>>> class Foo:
...   def __invert__(self):
...     print 'invert'
...
>>> x = Foo()
>>> operator.invert(x)
invert
>>> ~x
invert

Any class in which it is meaningful to have a "complement" or "inverse" of an instance that is also an instance of the same class is a possible candidate for the invert operator. However, operator overloading can lead to confusion if misused, so be sure that it really makes sense to do so before supplying an __invert__ method to your class. (Note that byte-strings [ex: '\xff'] do not support this operator, even though it is meaningful to invert all the bits of a byte-string.)

See the MSDN reference table for maximum numbers/sizes.

Bytes per varchar(max), varbinary(max), xml, text, or image column: 2^31-1

There's a two-byte overhead for the column, so the actual data is 2^31-3 max bytes in length. Assuming you're using a single-byte character encoding, that's 2^31-3 characters total. (If you're using a character encoding that uses more than one byte per character, divide by the total number of bytes per character. If you're using a variable-length character encoding, all bets are off.)

The name of the Series becomes the index of the row in the DataFrame:

In [99]: df = pd.DataFrame(np.random.randn(8, 4), columns=['A','B','C','D'])

In [100]: s = df.xs(3)

In [101]: s.name = 10

In [102]: df.append(s)
Out[102]: 
           A         B         C         D
0  -2.083321 -0.153749  0.174436  1.081056
1  -1.026692  1.495850 -0.025245 -0.171046

4   0.478302 -0.599752 -0.080577  0.468618
5   2.609004 -1.679299 -1.593016  1.172298

7   1.158530 -2.240124  0.851323 -0.240378
10 -0.940552  0.853073 -0.134842 -0.277135

Just remove the slash after Data and prepend the root:

<xsl:variable name="myVarA" select="/root/DataSet/Data[@Value1='2']/@Value2"/>

This version always returns the number of seconds difference as a positive number (same result as @freedeveloper's solution):

var seconds = System.Math.Abs((date1 - date2).TotalSeconds);

The problem is you either haven't closed your if or you need an elseif:

create procedure checando(
    in nombrecillo varchar(30),
    in contrilla varchar(30), 
    out resultado int)
begin 

    if exists (select * from compas where nombre = nombrecillo and contrasenia = contrilla) then
        set resultado = 0;
    elseif exists (select * from compas where nombre = nombrecillo) then
        set resultado = -1;
    else 
        set resultado = -2;
    end if;
end;

I'd try the following steps:

1) Check if there is a Byte Order Mark

2) Check if the file is valid UTF8

3) Use the local "ANSI" codepage (ANSI as Microsoft defines it)

Step 2 works because most non ASCII sequences in codepages other that UTF8 are not valid UTF8.

Go in to this folder and pull down the ENTIRE tools folder you mentioned above:

git clone git://github.com/raspberrypi/tools.git

You wanted to use the following of the 3 ones, gcc-linaro-arm-linux-gnueabihf-raspbian, if I did not read wrong.

Go into your home directory and add:

export PATH=$PATH:$HOME/raspberrypi/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin

to the end of the file named ~/.bashrc

Now you can either log out and log back in (i.e. restart your terminal session), or run . ~/.bashrc in your terminal to pick up the PATH addition in your current terminal session.

Now, verify that you can access the compiler arm-linux-gnueabihf-gcc -v. You should get something like this:

Using built-in specs.

But hey! I did that and the libs still don't work!

We're not done yet! So far, we've only done the basics.

In your raspberrypi folder, make a folder called rootfs.

Now you need to copy the entire /liband /usr directory to this newly created folder. I usually bring the rpi image up and copy it via rsync:

rsync -rl --delete-after --safe-links [email protected]:/{lib,usr} $HOME/raspberrypi/rootfs

where 192.168.1.PI is replaced by the IP of your Raspberry Pi.

Now, we need to write a cmake config file. Open ~/home/raspberrypi/pi.cmake in your favorite editor and insert the following:

SET(CMAKE_SYSTEM_NAME Linux)
SET(CMAKE_SYSTEM_VERSION 1)
SET(CMAKE_C_COMPILER $ENV{HOME}/raspberrypi/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin/arm-linux-gnueabihf-gcc)
SET(CMAKE_CXX_COMPILER $ENV{HOME}/raspberrypi/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin/arm-linux-gnueabihf-g++)
SET(CMAKE_FIND_ROOT_PATH $ENV{HOME}/raspberrypi/rootfs)
SET(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)
SET(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
SET(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)

Now you should be able to compile your cmake programs simply by adding this extra flag: -D CMAKE_TOOLCHAIN_FILE=$HOME/raspberrypi/pi.cmake.

Using a cmake hello world example:

git clone https://github.com/jameskbride/cmake-hello-world.git 
cd cmake-hello-world
mkdir build
cd build
cmake -D CMAKE_TOOLCHAIN_FILE=$HOME/raspberrypi/pi.cmake ../
make
scp CMakeHelloWorld [email protected]:/home/pi/
ssh [email protected] ./CMakeHelloWorld

It is mostly used for importing symbols from / exporting symbols to a shared library (DLL). Both Visual C++ and GCC compilers support __declspec(dllimport) and __declspec(dllexport). Other uses (some Microsoft-only) are documented in the MSDN.

You can set it on the command line via JVM parameters:

java -Duser.country=CA -Duser.language=fr ... com.x.Main

@Keith -

In your comparison between IEnumerable<int> and IEnumerable<double> you don't need to worry - if you pass the wrong type your code won't compile anyway.

That isn't quite true - if a method is overloaded to both IEnumerable<int> and IEnumerable<double> then it may silently pass the unexpected inferred type (due to some other change in the program) to the wrong overload hence causing incorrect behaviour.

I suppose the question is how likely it is that this sort of situation will come up!

I guess part of the problem is how much confusion var adds to a given declaration - if it's not clear what type something is (despite being strongly typed and the compiler understanding entirely what type it is) someone might gloss over a type safety error, or at least take longer to understand a piece of code.

you can also do it by async function to get all the users

await User.find({},(err,users)=>{

    if (err){
    return  res.status(422).send(err)
    }

    if (!users){
        return res.status(422).send({error:"No data in the collection"})
    }

    res.send({Allusers:users})

})

For the sake of readability

I am able to upgrade the node using following command

nvm install node --reinstall-packages-from=node

ASK YOURSELF

• Does the type person? have an apartment member/property? OR
• Does the type person have an apartment member/property?

If you can't answer this question, then continue reading:

_{To understand you may need super-basic level of understanding of Generics. See here. A lot of things in Swift are written using Generics. Optionals included}

The code below has been made available from this Stanford video. Highly recommend you to watch the first 5 minutes

An Optional is an enum with only 2 cases

enum Optional<T>{
    case None
    case Some(T)
}

let x: String? = nil //actually means:

let x = Optional<String>.None

let x :String? = "hello" //actually means:

let x = Optional<String>.Some("hello")

var y = x! // actually means:

switch x {
case .Some(let value): y = value
case .None: // Raise an exception
}

Optional binding:

let x:String? = something
if let y = x {
    // do something with y
}
//Actually means:

switch x{
case .Some(let y): print)(y) // or whatever else you like using 
case .None: break
}

when you say var john: Person? You actually mean such:

enum Optional<Person>{
case .None
case .Some(Person)
}

Does the above enum have any property named apartment? Do you see it anywhere? It's not there at all! However if you unwrap it ie do person! then you can ... what it does under the hood is : Optional<Person>.Some(Person(name: "John Appleseed"))

Had you defined var john: Person instead of: var john: Person? then you would have no longer needed to have the ! used, because Person itself does have a member of apartment

As a future discussion on why using ! to unwrap is sometimes not recommended see this Q&A

Have a look at git show-branch

There's a lot you can do with core git functionality. It might be good to specify what you'd like to include in your visual diff. Most answers focus on line-by-line diffs of commits, where your example focuses on names of files affected in a given commit.

One visual that seems not to be addressed is how to see the commits that branches contain (whether in common or uniquely).

For this visual, I'm a big fan of git show-branch; it breaks out a well organized table of commits per branch back to the common ancestor. - to try it on a repo with multiple branches with divergences, just type git show-branch and check the output - for a writeup with examples, see Compare Commits Between Git Branches

val() is more like a shortcut for attr('value'). For your usage use text() or html() instead

Declare password like DB_PASSWORD="2o0@#5TGR1NG" in .env file

If # sign include in your password then password will declare in between " ".

One way to approach the problem is to make the upload a two phase process. First, you would upload the file itself using a POST, where the server returns some identifier back to the client (an identifier might be the SHA1 of the file contents). Then, a second request associates the metadata with the file data:

{
    "Name": "Test",
    "Latitude": 12.59817,
    "Longitude": 52.12873,
    "ContentID": "7a788f56fa49ae0ba5ebde780efe4d6a89b5db47"
}

Including the file data base64 encoded into the JSON request itself will increase the size of the data transferred by 33%. This may or may not be important depending on the overall size of the file.

Another approach might be to use a POST of the raw file data, but include any metadata in the HTTP request header. However, this falls a bit outside basic REST operations and may be more awkward for some HTTP client libraries.

This is way I did it:

%matplotlib inline
import matplotlib.pyplot as plt
plt.rcParams["figure.figsize"] = (12, 9) # (w, h)

You can define your own sizes.

If you want a stack trace which looks very similar to how php formats the exception stack trace than use this function I wrote:

function debug_backtrace_string() {
    $stack = '';
    $i = 1;
    $trace = debug_backtrace();
    unset($trace[0]); //Remove call to this function from stack trace
    foreach($trace as $node) {
        $stack .= "#$i ".$node['file'] ."(" .$node['line']."): "; 
        if(isset($node['class'])) {
            $stack .= $node['class'] . "->"; 
        }
        $stack .= $node['function'] . "()" . PHP_EOL;
        $i++;
    }
    return $stack;
} 

This will return a stack trace formatted like this:

#1 C:\Inetpub\sitename.com\modules\sponsors\class.php(306): filePathCombine()
#2 C:\Inetpub\sitename.com\modules\sponsors\class.php(294): Process->_deleteImageFile()
#3 C:\Inetpub\sitename.com\VPanel\modules\sponsors\class.php(70): Process->_deleteImage()
#4 C:\Inetpub\sitename.com\modules\sponsors\process.php(24): Process->_delete() 

• socket.isConnected() returns always true once the client connects (and even after the disconnect) weird !!
• socket.getInputStream().read()
  • makes the thread wait for input as long as the client is connected and therefore makes your program not do anything - except if you get some input
  • returns -1 if the client disconnected
• socket.getInetAddress().isReachable(int timeout): From isReachable(int timeout)

  Test whether that address is reachable. Best effort is made by the implementation to try to reach the host, but firewalls and server configuration may block requests resulting in a unreachable status while some specific ports may be accessible. A typical implementation will use ICMP ECHO REQUESTs if the privilege can be obtained, otherwise it will try to establish a TCP connection on port 7 (Echo) of the destination host.

To me, it is better to put the transition codes with the original/minimum selectors than with the :hover or any other additional selectors:

#content #nav a {_x000D_
    background-color: #FF0;_x000D_
    _x000D_
    -webkit-transition: background-color 1000ms linear;_x000D_
    -moz-transition: background-color 1000ms linear;_x000D_
    -o-transition: background-color 1000ms linear;_x000D_
    -ms-transition: background-color 1000ms linear;_x000D_
    transition: background-color 1000ms linear;_x000D_
}_x000D_
_x000D_
#content #nav a:hover {_x000D_
    background-color: #AD310B;_x000D_
}

<div id="content">_x000D_
    <div id="nav">_x000D_
        <a href="#link1">Link 1</a>_x000D_
    </div>_x000D_
</div>

Simply use

java.util.Collections.sort(list)

without String.CASE_INSENSITIVE_ORDER comparator parameter.

Case 1 : Yes, this works fine.

Case 2 : This will fail with the error ORA-01441 : cannot decrease column length because some value is too big.

RSS is Resident Set Size (physically resident memory - this is currently occupying space in the machine's physical memory), and VSZ is Virtual Memory Size (address space allocated - this has addresses allocated in the process's memory map, but there isn't necessarily any actual memory behind it all right now).

Note that in these days of commonplace virtual machines, physical memory from the machine's view point may not really be actual physical memory.

Okay, found this one myself. You can use Ctrl+Alt+F9 to accomplish this.

it almost can ..

 ls -l | awk '{k=0;for(i=0;i<=8;i++)k+=((substr($1,i+2,1)~/[rwx]/) \
             *2^(8-i));if(k)printf("%0o ",k);print}'

I know this is old... But I was having the same problem today and found a solution:

Model.find_by_sql

If you want to instantiate the results:

Client.find_by_sql("
  SELECT * FROM clients
  INNER JOIN orders ON clients.id = orders.client_id
  ORDER BY clients.created_at desc
")
# => [<Client id: 1, first_name: "Lucas" >, <Client id: 2, first_name: "Jan">...]

Model.connection.select_all('sql').to_hash

If you just want a hash of values:

Client.connection.select_all("SELECT first_name, created_at FROM clients
   WHERE id = '1'").to_hash
# => [
  {"first_name"=>"Rafael", "created_at"=>"2012-11-10 23:23:45.281189"},
  {"first_name"=>"Eileen", "created_at"=>"2013-12-09 11:22:35.221282"}
]

Result object:

select_all returns a result object. You can do magic things with it.

result = Post.connection.select_all('SELECT id, title, body FROM posts')
# Get the column names of the result:
result.columns
# => ["id", "title", "body"]

# Get the record values of the result:
result.rows
# => [[1, "title_1", "body_1"],
      [2, "title_2", "body_2"],
      ...
     ]

# Get an array of hashes representing the result (column => value):
result.to_hash
# => [{"id" => 1, "title" => "title_1", "body" => "body_1"},
      {"id" => 2, "title" => "title_2", "body" => "body_2"},
      ...
     ]

# ActiveRecord::Result also includes Enumerable.
result.each do |row|
  puts row['title'] + " " + row['body']
end

Three solutions not officially, explicitly mentioned:

ArrayList<String> doThings() {
  //
}

void doThings(ArrayList<String> list) {
  //
}

Pair<String, String> doThings() {
  //
}

For Pair, I would recommend: https://commons.apache.org/proper/commons-lang/apidocs/org/apache/commons/lang3/tuple/Pair.html

I suggest also checking how much memory is currently being used.

It turns out that the inability to find these DLL files was the first symptom exhibited when trying to run a program (either run or debug) in Visual Studio.

After over a half hour with much head scratching, searching the web, running Process Monitor, and Task Manager, and depends, a completely different program that had been running since the beginning of time reported that "memory is low; try stopping some programs" or some such. After killing Firefox, Thunderbird, Process Monitor, and depends, everything worked again.

Just add this function and call it, it will convert List to DataTable.

public static DataTable ToDataTable<T>(List<T> items)
{
        DataTable dataTable = new DataTable(typeof(T).Name);

        //Get all the properties
        PropertyInfo[] Props = typeof(T).GetProperties(BindingFlags.Public | BindingFlags.Instance);
        foreach (PropertyInfo prop in Props)
        {
            //Defining type of data column gives proper data table 
            var type = (prop.PropertyType.IsGenericType && prop.PropertyType.GetGenericTypeDefinition() == typeof(Nullable<>) ? Nullable.GetUnderlyingType(prop.PropertyType) : prop.PropertyType);
            //Setting column names as Property names
            dataTable.Columns.Add(prop.Name, type);
        }
        foreach (T item in items)
        {
           var values = new object[Props.Length];
           for (int i = 0; i < Props.Length; i++)
           {
                //inserting property values to datatable rows
                values[i] = Props[i].GetValue(item, null);
           }
           dataTable.Rows.Add(values);
      }
      //put a breakpoint here and check datatable
      return dataTable;
}

Try following code:

File file = new File("infilename");

// Get the number of bytes in the file
long sizeInBytes = file.length();
//transform in MB
long sizeInMb = sizeInBytes / (1024 * 1024);

Since most of the answers to this question are between 2009 and 2014 (except for a comment in 2018), there should be an update to this.

I found a solution to the wrap-text problem brought up by Spongman on Jun 11 '14 at 23:20. He has an example here: jsfiddle.net/vPpD4

If you add the following in the CSS under the div tag in the jsfiddle.net/vPpD4 example, you get the desired wrap-text effect that I think Spongman was asking about. I don't know how far back this is applicable, but this works in all of the current (as of Dec 2020/Jan 2021) browsers available for Windows computers. Note: I have not tested this on the Apple Safari browser. I have also not tested this on any mobile devices.

    div img { 
        float: left;
    }
    .clearfix::after {
        content: ""; 
        clear: both;
        display: table;
    }

I also added a border around the image, just so that the reader will understand where the edge of the image is and why the text wraps as it does. The resulting example looks is here: http://jsfiddle.net/tqg7hLzk/

In .Net Core this is much easier now. In your startup.cs just add json options and you can configure the settings there.

public void ConfigureServices(IServiceCollection services)

....

services.AddMvc().AddJsonOptions(options =>
{
   options.SerializerSettings.NullValueHandling = NullValueHandling.Ignore;               
});

.loc and .iloc are used for indexing, i.e., to pull out portions of data. In essence, the difference is that .loc allows label-based indexing, while .iloc allows position-based indexing.

If you get confused by .loc and .iloc, keep in mind that .iloc is based on the index (starting with i) position, while .loc is based on the label (starting with l).

.loc

.loc is supposed to be based on the index labels and not the positions, so it is analogous to Python dictionary-based indexing. However, it can accept boolean arrays, slices, and a list of labels (none of which work with a Python dictionary).

iloc

.iloc does the lookup based on index position, i.e., pandas behaves similarly to a Python list. pandas will raise an IndexError if there is no index at that location.

Examples

The following examples are presented to illustrate the differences between .iloc and .loc. Let's consider the following series:

>>> s = pd.Series([11, 9], index=["1990", "1993"], name="Magic Numbers")
>>> s
1990    11
1993     9
Name: Magic Numbers , dtype: int64

.iloc Examples

>>> s.iloc[0]
11
>>> s.iloc[-1]
9
>>> s.iloc[4]
Traceback (most recent call last):
    ...
IndexError: single positional indexer is out-of-bounds
>>> s.iloc[0:3] # slice
1990 11
1993  9
Name: Magic Numbers , dtype: int64
>>> s.iloc[[0,1]] # list
1990 11
1993  9
Name: Magic Numbers , dtype: int64

.loc Examples

>>> s.loc['1990']
11
>>> s.loc['1970']
Traceback (most recent call last):
    ...
KeyError: ’the label [1970] is not in the [index]’
>>> mask = s > 9
>>> s.loc[mask]
1990 11
Name: Magic Numbers , dtype: int64
>>> s.loc['1990':] # slice
1990    11
1993     9
Name: Magic Numbers, dtype: int64

Because s has string index values, .loc will fail when indexing with an integer:

>>> s.loc[0]
Traceback (most recent call last):
    ...
KeyError: 0

If you take advantage of width: 100vw; and height: 100vh;, the object with these styles applied will stretch to the full width and height of the device.

Also note, there are times padding and margins can get added to your view, by browsers and the like. I added a * global no padding and margins so you can see the difference. Keep this in mind.

I have noticed that no one mentioned WorkManger solution which is better and support most of android devices.

You should have a Worker with network constraint AND it will fired only if network available, i.e:

val constraints = Constraints.Builder().setRequiredNetworkType(NetworkType.CONNECTED).build()
val worker = OneTimeWorkRequestBuilder<MyWorker>().setConstraints(constraints).build()

And in worker you do whatever you want once connection back, you may fire the worker periodically .

i.e:

inside dowork() callback:

notifierLiveData.postValue(info)

Brendan is correct. You can edit the Select command to edit a filtered list of records. For instance "WHERE dept_no = 200".

If you want to add an interval before executing the cron the next time you can add a sleep

for i in {1..100}; do echo $i && curl "http://URL" >> /tmp/output.log && sleep 120; done

You need to SAVE your code file with the ".py" extension. Then, on the 'Tools/Build System' menu, make sure your build system is set to either 'auto' or 'Python'. What that message is telling you is there is no valid Python file to 'build' (or, in this case just run).

If you're using SASS you could also use this mixin:

@mixin headings {
    h1, h2, h3,
    h4, h5, h6 {
        @content;
    }
}

Use it like so:

@include headings {
    font: 32px/42px trajan-pro-1, trajan-pro-2;
}

Edit: My personal favourite way of doing this by optionally extending a placeholder selector on each of the heading elements.

h1, h2, h3,
h4, h5, h6 {
    @extend %headings !optional;
}

Then I can target all headings like I would target any single class, for example:

.element > %headings {
    color: red;
}

Okay so little bit of digging and I found these gems from Bill Philips article on RecycleView

RecyclerView can do more than ListView, but the RecyclerView class itself has fewer responsibilities than ListView. Out of the box, RecyclerView does not:

• Position items on the screen
• Animate views
• Handle any touch events apart from scrolling

All of this stuff was baked in to ListView, but RecyclerView uses collaborator classes to do these jobs instead.

The ViewHolders you create are beefier, too. They subclass RecyclerView.ViewHolder, which has a bunch of methods RecyclerView uses. ViewHolders know which position they are currently bound to, as well as which item ids (if you have those). In the process, ViewHolder has been knighted. It used to be ListView’s job to hold on to the whole item view, and ViewHolder only held on to little pieces of it.

Now, ViewHolder holds on to all of it in the ViewHolder.itemView field, which is assigned in ViewHolder’s constructor for you.

You should check out the new Eclipse 2019-09 4.13 Quick Search feature

The new Quick Search dialog provides a convenient, simple and fast way to run a textual search across your workspace and jump to matches in your code.

The dialog provides a quick overview showing matching lines of text at a glance.
It updates as quickly as you can type and allows for quick navigation using only the keyboard.

A typical workflow starts by pressing the keyboard shortcut Ctrl+Alt+Shift+L
(or Cmd+Alt+Shift+L on Mac).
Typing a few letters updates the search result as you type.
Use Up-Down arrow keys to select a match, then hit Enter to open it in an editor.

Load an image with characters as texture and draw the part of that texture depending on what character you want. You can create that texture using a paint program, hardcode it or use a window component to draw to an image and retrieve that image for an exact copy of system fonts.

No need to use Glut or any other extension, just basic OpenGL operability. It gets the job done, not to mention that its been done like this for decades by professional programmers in very succesfull games and other applications.

If you only want form elements that have a name attribute, you can filter the form elements.

const form = document.querySelector("your-form")
Array.from(form.elements).filter(e => e.getAttribute("name"))

Yes, according to iTunes Connect Export Compliance Information screens, if you use built-in iOS or MacOS encryption (keychain, https), you are using encryption for purposes of US Government Export regulations. Whether you qualify for an export compliance exemption depends on what your app does and how it uses this encryption. Attached images show the iTunes Connect Export Compliance Screens to help you determine your export reporting obligations. In particular, it states:

If you are making use of ATS or making a call to HTTPS please note that you are required to submit a year-end self classification report to the US government. Learn more

The package react-app-rewired can be used to remove the plugin. This way you do not have to eject.

Follow the steps on the npm package page (install the package and flip the calls in the package.json file) and use a config-overrides.js file similar to this one:

const ModuleScopePlugin = require('react-dev-utils/ModuleScopePlugin');

module.exports = function override(config, env) {
    config.resolve.plugins = config.resolve.plugins.filter(plugin => !(plugin instanceof ModuleScopePlugin));

    return config;
};

This will remove the ModuleScopePlugin from the used WebPack plugins, but leave the rest as it was and removes the necessity to eject.

The top answer is not suitable when values may have length less than 4.

In T-SQL

You will get "Invalid length parameter passed to the right function" because it doesn't accept negatives. Use a CASE statement:

SELECT case when len(foo) >= 4 then RIGHT(foo, LEN(foo) - 4) else '' end AS myfoo from mytable;

In Postgres

Values less than 4 give the surprising behavior below instead of an error, because passing negative values to RIGHT trims the first characters instead of the entire string. It makes more sense to use RIGHT(MyColumn, -5) instead.

An example comparing what you get when you use the top answer's "length - 5" instead of "-5":

create temp table foo (foo) as values ('123456789'),('12345678'),('1234567'),('123456'),('12345'),('1234'),('123'),('12'),('1'), ('');

select foo, right(foo, length(foo) - 5), right(foo, -5) from foo;

foo       len(foo) - 5  just -5   
--------- ------------  -------     
123456789 6789          6789 
12345678  678           678  
1234567   67            67   
123456    6             6    
12345                       
1234      234

Just googled it, and found here a handy function that is useful for converting stdClass object to array recursively.

<?php
function object_to_array($object) {
 if (is_object($object)) {
  return array_map(__FUNCTION__, get_object_vars($object));
 } else if (is_array($object)) {
  return array_map(__FUNCTION__, $object);
 } else {
  return $object;
 }
}
?>

EDIT: I updated this answer with content from linked source (which is also changed now), thanks to mason81 for suggesting me.

A nice technique i've started using with some of my apps on express is to create an object which merges the query, params, and body fields of express's request object.

//./express-data.js
const _ = require("lodash");

class ExpressData {

    /*
    * @param {Object} req - express request object
    */
    constructor (req) {

        //Merge all data passed by the client in the request
        this.props = _.merge(req.body, req.params, req.query);
     }

}

module.exports = ExpressData;

Then in your controller body, or anywhere else in scope of the express request chain, you can use something like below:

//./some-controller.js

const ExpressData = require("./express-data.js");
const router = require("express").Router();


router.get("/:some_id", (req, res) => {

    let props = new ExpressData(req).props;

    //Given the request "/592363122?foo=bar&hello=world"
    //the below would log out 
    // {
    //   some_id: 592363122,
    //   foo: 'bar',
    //   hello: 'world'
    // }
    console.log(props);

    return res.json(props);
});

This makes it nice and handy to just "delve" into all of the "custom data" a user may have sent up with their request.

Note

Why the 'props' field? Because that was a cut-down snippet, I use this technique in a number of my APIs, I also store authentication / authorisation data onto this object, example below.

/*
 * @param {Object} req - Request response object
*/
class ExpressData {

    /*
    * @param {Object} req - express request object
    */
    constructor (req) {

        //Merge all data passed by the client in the request
        this.props = _.merge(req.body, req.params, req.query);

        //Store reference to the user
        this.user = req.user || null;

        //API connected devices (Mobile app..) will send x-client header with requests, web context is implied.
        //This is used to determine how the user is connecting to the API 
        this.client = (req.headers) ? (req.headers["x-client"] || (req.client || "web")) : "web";
    }
} 

By the power of Google I found a blogpost from 2007 which gives the following regex that matches string which don't contains a certain substring:

^((?!my string).)*$

It works as follows: it looks for zero or more (*) characters (.) which do not begin (?! - negative lookahead) your string and it stipulates that the entire string must be made up of such characters (by using the ^ and $ anchors). Or to put it an other way:

The entire string must be made up of characters which do not begin a given string, which means that the string doesn't contain the given substring.

Why not do a recursive search to find all instances in sub directories:

grep -r 'text' *

This works like a charm.

Try this:

string foo = @"D:\Projects\Some\Kind\Of\Pathproblem\wuhoo.xml";

The problem is that in a string, a \ is an escape character. By using the @ sign you tell the compiler to ignore the escape characters.

You can also get by with escaping the \:

string foo = "D:\\Projects\\Some\\Kind\\Of\\Pathproblem\\wuhoo.xml";

A method is a function that takes a class instance as its first parameter. Methods are members of classes.

class C:
    def method(self, possibly, other, arguments):
        pass # do something here

As you wanted to know what it specifically means in Python, one can distinguish between bound and unbound methods. In Python, all functions (and as such also methods) are objects which can be passed around and "played with". So the difference between unbound and bound methods is:

1) Bound methods

# Create an instance of C and call method()
instance = C()

print instance.method # prints '<bound method C.method of <__main__.C instance at 0x00FC50F8>>'
instance.method(1, 2, 3) # normal method call

f = instance.method
f(1, 2, 3) # method call without using the variable 'instance' explicitly

Bound methods are methods that belong to instances of a class. In this example, instance.method is bound to the instance called instance. Everytime that bound method is called, the instance is passed as first parameter automagically - which is called self by convention.

2) Unbound methods

print C.method # prints '<unbound method C.method>'
instance = C()
C.method(instance, 1, 2, 3) # this call is the same as...
f = C.method
f(instance, 1, 2, 3) # ..this one...

instance.method(1, 2, 3) # and the same as calling the bound method as you would usually do

When you access C.method (the method inside a class instead of inside an instance), you get an unbound method. If you want to call it, you have to pass the instance as first parameter because the method is not bound to any instance.

Knowing that difference, you can make use of functions/methods as objects, like passing methods around. As an example use case, imagine an API that lets you define a callback function, but you want to provide a method as callback function. No problem, just pass self.myCallbackMethod as the callback and it will automatically be called with the instance as first argument. This wouldn't be possible in static languages like C++ (or only with trickery).

Hope you got the point ;) I think that is all you should know about method basics. You could also read more about the classmethod and staticmethod decorators, but that's another topic.

$('input[type="button"]').click(function (e) {
    if (e.target) {
        alert(e.target.id + ' clicked');
    }
});

you should tweak this a little (eg. use a name in stead of an id to alert), but this way you have more generic function.

Don't overlook the preservation of white space. If you want to process 'fred flinstone' and you get 'Fred Flinstone' instead of 'Fred Flinstone', you've corrupted your white space. Some of the above solutions will lose white space. Here's a solution that's good for Python 2 and 3 and preserves white space.

def propercase(s):
    return ''.join(map(''.capitalize, re.split(r'(\s+)', s)))

If you are using Laravel eloquent you may try this as well.

$result = self::select('*')
                    ->with('user')
                    ->where('subscriptionPlan', function($query) use($activated){
                        $query->where('activated', '=', $roleId);
                    })
                    ->get();

As per your requirement you dont have to generate a html page dynamicaly. It can be done by .htaccess file .

Still this is sample code to generate HTML Page

<?php

 $filename = 'test.html';
 header("Cache-Control: public");
 header("Content-Description: File Transfer");
 header("Content-Disposition: attachment; filename=$filename");
 header("Content-Type: application/octet-stream; ");
 header("Content-Transfer-Encoding: binary");
?>

you can create any .html , .php file just change extention in file name

Try to Use:

select * from sys.objects where type='tr' and name like '%_Insert%'

Also note that if the textSize is set in code, calling textView.setTextSize(X) interprets the number (X) as SP. Use setTextSize(TypedValue.COMPLEX_UNIT_DIP, X) to set values in dp.

In objectMapper we have writeValueAsString() which accepts object as parameter. We can pass object list as parameter get the string back.

List<Apartment> aptList =  new ArrayList<Apartment>();
    Apartment aptmt = null;
    for(int i=0;i<5;i++){
         aptmt= new Apartment();
         aptmt.setAptName("Apartment Name : ArrowHead Ranch");
         aptmt.setAptNum("3153"+i);
         aptmt.setPhase((i+1));
         aptmt.setFloorLevel(i+2);
         aptList.add(aptmt);
    }
mapper.writeValueAsString(aptList)

In Unix shells, you can quote almost every character in single quotes '. Except the single quote itself, and you can't express control characters, because \ is not expanded. Accessing the single quote itself from within a quoted string is possible, because you can concatenate strings with single and double quotes, like 'I'"'"'m' which can be used to access a file called "I'm" (double quote also possible here).

So you should avoid all control characters, because they are too difficult to enter in the shell. The rest still is funny, especially files starting with a dash, because most commands read those as options unless you have two dashes -- before, or you specify them with ./, which also hides the starting -.

If you want to be nice, don't use any of the characters the shell and typical commands use as syntactical elements, sometimes position dependent, so e.g. you can still use -, but not as first character; same with ., you can use it as first character only when you mean it ("hidden file"). When you are mean, your file names are VT100 escape sequences ;-), so that an ls garbles the output.

Make a function to take care of it, and pass it parameters with the styles you want changed..

function setStyle( objId, propertyObject )
{
 var elem = document.getElementById(objId);
 for (var property in propertyObject)
    elem.style[property] = propertyObject[property];
}

and call it like this

setStyle('myElement', {'fontsize':'12px', 'left':'200px'});

for the values of the properties inside the propertyObject you can use variables..

Be careful when accessing DateTime.Now twice, as it's possible for the calls to straddle midnight and you'll get wacky results on rare occasions and be left scratching your head.

To be safe, you should assign DateTime.Now to a local variable first if you're going to use it more than once:

var now = DateTime.Now;
var time = now.ToString("hh:mm:ss tt");
var date = now.ToString("MM/dd/yy");

Note the use of lower case "hh" do display hours from 00-11 even in the afternoon, and "tt" to show AM/PM, as the question requested. If you want 24 hour clock 00-23, use "HH".

Sometimes using   instead of spaces will work. Clearly it has drawbacks, though.

This works in Windows; didn't check Linux but don't see why it wouldn't work. Download the zip files for 5.6.8 portable. Unzip the files and copy the xampp/htdocs to the xampp/htdocs in your install directory.

There are three options, that you can use. -I is to exclude binary files in grep. Other are for line numbers and file names.

grep -I -n -H 


-I -- process a binary file as if it did not contain matching data; 
-n -- prefix each line of output with the 1-based line number within its input file
-H -- print the file name for each match

So this might be a way to run grep:

grep -InH your-word *

Set-ExecutionPolicy -ExecutionPolicy Bypass -Scope Process

The above command worked for me even when the following error happens:

Access to the registry key 'HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell\1\ShellIds\Microsoft.PowerShell' is denied.

Try enclosing your date into a character string.

 select * 
 from dbo.March2010 A
 where A.Date >= '2010-04-01';

Do NOT do that! setNum(num);//fix- until someone fixes your setter. Your getter should not call your setter with the uninitialized value ofnum(e.g.0`).

I suggest making a few small changes -

public static class Vars {   private int num = 5; // Default to 5.    public void setNum(int x) {     this.num = x; // actually "set" the value.   }    public int getNum() {     return num;   } } 

$request = [System.Net.WebRequest]::Create('http://stackoverflow.com/questions/20259251/powershell-script-to-check-the-status-of-a-url')

$response = $request.GetResponse()

$response.StatusCode

$response.Close()

No real answer to your question but:
Generally relying on the clients IP address is in my opinion not a good practice as it is not usable to identify clients in a unique fashion.

Problems on the road are that there are quite a lot scenarios where the IP does not really align to a client:

• Proxy/Webfilter (mangle almost everything)
• Anonymizer network (no chance here either)
• NAT (an internal IP is not very useful for you)
• ...

I cannot offer any statistics on how many IP addresses are on average reliable but what I can tell you that it is almost impossible to tell if a given IP address is the real clients address.

var joinedString= string.Join(";", myDict.Select(x => x.Key + "=" + x.Value));

If you want to pass the data using POST instead of GET, you can do it using a combination of PHP and JavaScript, like this:

function formSubmit(house_number)
{
  document.forms[0].house_number.value = house_number;
  document.forms[0].submit();
}

Then in PHP you loop through the house-numbers, and create links to the JavaScript function, like this:

<form action="house.php" method="POST">
<input type="hidden" name="house_number" value="-1">

<?php
foreach ($houses as $id => name)
{
    echo "<a href=\"javascript:formSubmit($id);\">$name</a>\n";
}
?>
</form>

That way you just have one form whose hidden variable(s) get modified according to which link you click on. Then JavasScript submits the form.

I see this has been answered, but it seems like you could avoid all of this 'remapping' of the enter key by simply hooking your validation into the AcceptButton on a form. ie. you have 3 textboxes (txtA,txtB,txtC) and an 'OK' button set to be AcceptButton (and TabOrder set properly). So, if in txtA and you hit enter, if the data is invalid, your focus will stay in txtA, but if it is valid, assuming the other txts need input, validation will just put you into the next txt that needs valid input thus simulating TAB behaviour... once all txts have valid input, pressing enter will fire a succsessful validation and close form (or whatever...) Make sense?

If you use Spring you could use

org.springframework.util.StringUtils.stripFilenameExtension(String path)

Strip the filename extension from the given Java resource path, e.g.

"mypath/myfile.txt" -> "mypath/myfile".

Params: path – the file path

Returns: the path with stripped filename extension

Try this code:

<input type="text" name="Phone Number" pattern="[7-9]{1}[0-9]{9}" 
       title="Phone number with 7-9 and remaing 9 digit with 0-9">

This code will inputs only in the following format:

9238726384 (starting with 9 or 8 or 7 and other 9 digit using any number)
8237373746
7383673874

Incorrect format:
2937389471(starting not with 9 or 8 or 7)
32796432796(more than 10 digit)
921543(less than 10 digit)

try this:

legend.green-color a:hover{
    text-decoration: none;
}

If you need the index of the item you're working with then using a foreach loop is the wrong method of iterating over the collection. Change the way you're looping so you have the index:

for(int i = 0; i < dt.Rows.Count; i++)
{
    // your index is in i
    var row = dt.Rows[i];
}

As an addendum to the previous answers -- there's a workaround I just discovered for if you can't or don't want to add all this boilerplate to your project POM. If you look in the following location:

{Eclipse_folder}/plugins/org.eclipse.m2e.lifecyclemapping.defaults_{m2e_version}

You should find a file called lifecycle-mapping-metadata.xml where you can make the same changes described in the other answers and in M2E plugin execution not covered.

origin is an alias on your system for a particular remote repository. It's not actually a property of that repository.

By doing

git push origin branchname

you're saying to push to the origin repository. There's no requirement to name the remote repository origin: in fact the same repository could have a different alias for another developer.

Remotes are simply an alias that store the URL of repositories. You can see what URL belongs to each remote by using

git remote -v

In the push command, you can use remotes or you can simply use a URL directly. An example that uses the URL:

git push [email protected]:git/git.git master

Beamer just delegates responsibility for managing layout of itemize environments back to the base LaTeX packages, so there's nothing funky you need to do in Beamer itself to alter the apperaance / layout of your lists.

Since Beamer redefines itemize, item, etc., the fully proper way to manipulate things like indentation is to redefine the Beamer templates. I get the impression that you're not looking to go that far, but if that's not the case, let me know and I'll elaborate.

There are at least three ways of accomplishing your goal from within your document, without mussing about with Beamer templates.

With itemize

In the following code snippet, you can change the value of \itemindent from 0em to whatever you please, including negative values. 0em is the default item indentation.

The advantage of this method is that the list is styled normally. The disadvantage is that Beamer's redefinition of itemize and \item means that the number of paramters that can be manipulated to change the list layout is limited. It can be very hard to get the spacing right with multi-line items.

\begin{itemize}
  \setlength{\itemindent}{0em}
  \item This is a normally-indented item.
\end{itemize}

With list

In the following code snippet, the second parameter to \list is the bullet to use, and the third parameter is a list of layout parameters to change. The \leftmargin parameter adjusts the indentation of the entire list item and all of its rows; \itemindent alters the indentation of subsequent lines.

The advantage of this method is that you have all of the flexibility of lists in non-Beamer LaTeX. The disadvantage is that you have to setup the bullet style (and other visual elements) manually (or identify the right command for the template you're using). Note that if you leave the second argument empty, no bullet will be displayed and you'll save some horizontal space.

\begin{list}{$\square$}{\leftmargin=1em \itemindent=0em}
  \item This item uses the margin and indentation provided above.
\end{list}

Defining a customlist environment

The shortcomings of the list solution can be ameliorated by defining a new customlist environment that basically redefines the itemize environment from Beamer but also incorporates the \leftmargin and \itemindent (etc.) parameters. Put the following in your preamble:

\makeatletter
\newenvironment{customlist}[2]{
  \ifnum\@itemdepth >2\relax\@toodeep\else
      \advance\@itemdepth\@ne%
      \beamer@computepref\@itemdepth%

Now, to use an itemized list with custom indentation, you can use the following environment. The first argument is for \leftmargin and the second is for \itemindent. The default values are 2.5em and 0em respectively.

\begin{customlist}{2.5em}{0em}
   \item Any normal item can go here.
\end{customlist}

A custom bullet style can be incorporated into the customlist solution using the standard Beamer mechanism of \setbeamertemplate. (See the answers to this question on the TeX Stack Exchange for more information.)

Alternatively, the bullet style can just be modified directly within the environment, by replacing \usebeamertemplate{itemize \beameritemnestingprefix item} with whatever bullet style you'd like to use (e.g. $\square$).

I have written myself a function that converts most of the stuff one may want to send via AJAX to GET of POST query.
Following part of the function might be of interest:

  if(data.tagName!=null&&data.tagName.toUpperCase()=="FORM") {
    //Get all the input elements in form
    var elem = data.elements;
    //Loop through the element array
    for(var i = 0; i < elem.length; i++) {
      //Ignore elements that are not supposed to be sent
      if(elem[i].disabled!=null&&elem[i].disabled!=false||elem[i].type=="button"||elem[i].name==null||(elem[i].type=="checkbox"&&elem[i].checked==false))
        continue; 
      //Add & to any subsequent entries (that means every iteration except the first one) 
      if(data_string.length>0)
        data_string+="&";
      //Get data for selectbox
      if (elem[i].tagName.toUpperCase() == "SELECT")
      {
        data_string += elem[i].name + "=" + encodeURIComponent(elem[i].options[elem[i].selectedIndex].value) ;
      }
      //Get data from checkbox
      else if(elem[i].type=="checkbox")
      {
        data_string += elem[i].name + "="+(elem[i].value==null?"on":elem[i].value);
      }
      //Get data from textfield
      else
      {
        data_string += elem[i].name + (elem[i].value!=""?"=" + encodeURIComponent(elem[i].value):"=");
      }
    }
    return data_string; 
  }

It does not need jQuery since I don't use it. But I'm sure jquery's $.post accepts string as seconf argument.

Here is the whole function, other parts are not commented though. I can't promise there are no bugs in it:

function ajax_create_request_string(data, recursion) {
  var data_string = '';
  //Zpracovani formulare
  if(data.tagName!=null&&data.tagName.toUpperCase()=="FORM") {
    //Get all the input elements in form
    var elem = data.elements;
    //Loop through the element array
    for(var i = 0; i < elem.length; i++) {
      //Ignore elements that are not supposed to be sent
      if(elem[i].disabled!=null&&elem[i].disabled!=false||elem[i].type=="button"||elem[i].name==null||(elem[i].type=="checkbox"&&elem[i].checked==false))
        continue; 
      //Add & to any subsequent entries (that means every iteration except the first one) 
      if(data_string.length>0)
        data_string+="&";
      //Get data for selectbox
      if (elem[i].tagName.toUpperCase() == "SELECT")
      {
        data_string += elem[i].name + "=" + encodeURIComponent(elem[i].options[elem[i].selectedIndex].value) ;
      }
      //Get data from checkbox
      else if(elem[i].type=="checkbox")
      {
        data_string += elem[i].name + "="+(elem[i].value==null?"on":elem[i].value);
      }
      //Get data from textfield
      else
      {
        if(elem[i].className.indexOf("autoempty")!=-1) {
          data_string += elem[i].name+"=";
        }
        else
          data_string += elem[i].name + (elem[i].value!=""?"=" + encodeURIComponent(elem[i].value):"=");
      }
    }
    return data_string; 
  }
  //Loop through array
  if(data instanceof Array) {
    for(var i=0; i<data.length; i++) {
      if(data_string!="")
        data_string+="&";
      data_string+=recursion+"["+i+"]="+data[i];
    }
    return data_string;
  }
  //Loop through object (like foreach)
  for(var i in data) {
    if(data_string!="")
      data_string+="&";
    if(typeof data[i]=="object") {
      if(recursion==null)
        data_string+= ajax_create_request_string(data[i], i);
      else
        data_string+= ajax_create_request_string(data[i], recursion+"["+i+"]");
    }
    else if(recursion==null)
      data_string+=i+"="+data[i];
    else 
      data_string+=recursion+"["+i+"]="+data[i];
  }
  return data_string;
}

The difference between page and window with respect to WPF: Page vs Window in WPF?

First run this command

pip install jupyter

then add system variable path , this path is where jupyter and other scripts are located

PATH = C:\Users<userName>\AppData\Roaming\Python\Python38\Scripts

e.g PATH=C:\Users\HP\AppData\Roaming\Python\Python38\Scripts

After that we can run jupyter from any folder/directory

If you want to handle IPV6 in standard notation there are 8 groups of 4 hex digits:

2001:0dc5:72a3:0000:0000:802e:3370:73E4

32 hex digits + 7 separators = 39 characters.

CAUTION: If you also want to hold IPV4 addresses mapped as IPV6 addresses, use 45 characters as @Deepak suggests.

Yes, you could append ;Connection Timeout=30 to your connection string and specify the value you wish.

The timeout value set in the Connection Timeout property is a time expressed in seconds. If this property isn't set, the timeout value for the connection is the default value (15 seconds).

Moreover, setting the timeout value to 0, you are specifying that your attempt to connect waits an infinite time. As described in the documentation, this is something that you shouldn't set in your connection string:

A value of 0 indicates no limit, and should be avoided in a ConnectionString because an attempt to connect waits indefinitely.

For Debian Jessie and Stretch installing the following packages resolves the issue:

sudo apt install libblas3 liblapack3 liblapack-dev libblas-dev

Your next issue is very likely going to be a missing Fortran compiler, resolve this by installing it like this:

sudo apt install gfortran

If you want an optimized scipy, you can also install the optional libatlas-base-dev package:

sudo apt install libatlas-base-dev

If you have any issue with a missing Python.h file like this:

Then have a look at this post: https://stackoverflow.com/a/21530768/209532

Player.cpp require the definition of Ball class. So simply add #include "Ball.h"

Player.cpp:

#include "Player.h"
#include "Ball.h"

void Player::doSomething(Ball& ball) {
    ball.ballPosX += 10;                   // incomplete type error occurs here.
}

There is also the java.lang.Integer.toString(int i, int base) method, which would be more appropriate if your code might one day handle bases other than 2 (binary). Keep in mind that this method only gives you an unsigned representation of the integer i, and if it is negative, it will tack on a negative sign at the front. It won't use two's complement.

random_matrix = [[random.random for j in range(collumns)] for i in range(rows)
for i in range(rows):
    print random_matrix[i]

It seems you're actually talking about an MVC (Model-View-Controller) pattern, where logic is separated into various "tiers". Django, as a framework, follows MVC (loosely). You have models that contain your business logic and relate directly to tables in your database, views which in effect act like the controller, handling requests and returning responses, and finally, templates which handle presentation.

Django isn't just one of these, it is a complete framework for application development and provides all the tools you need for that purpose.

Frontend vs Backend is all semantics. You could potentially build a Django app that is entirely "backend", using its built-in admin contrib package to manage the data for an entirely separate application. Or, you could use it solely for "frontend", just using its views and templates but using something else entirely to manage the data. Most usually, it's used for both. The built-in admin (the "backend"), provides an easy way to manage your data and you build apps within Django to present that data in various ways. However, if you were so inclined, you could also create your own "backend" in Django. You're not forced to use the default admin.

In JavaScript when you create any object through a constructor call like below

step 1 : create a function say Person..

function Person(name){
this.name=name;
}
person.prototype.print=function(){
console.log(this.name);
}

step 2 : create an instance for this function..

var obj=new Person('venkat')

//above line will instantiate this function(Person) and return a brand new object called Person {name:'venkat'}

if you don't want to instantiate this function and call at same time.we can also do like below..

var Person = {
  init: function(name){
    this.name=name;
  },
  print: function(){
    console.log(this.name);
  }
};
var obj=Object.create(Person);
obj.init('venkat');
obj.print();

in the above method init will help in instantiating the object properties. basically init is like a constructor call on your class.

I share with you a code that can be useful, it is to create an annotation that can be used either in a class or a method.

@Target({TYPE, METHOD})
@Retention(RUNTIME)
@Documented
public @interface AnnotationLogger {
    /**
     * It is the parameter is to show arguments in the method or the class.
     */
    boolean showArguments() default false;
}


@Aspect
@Component
public class AnnotationLoggerAspect {
    
    @Autowired 
    private Logger logger;  
    
    private static final String METHOD_NAME   = "METHOD NAME: {} ";
    private static final String ARGUMENTS     = "ARGS: {} ";
    
    @Before(value = "@within(com.org.example.annotations.AnnotationLogger) || @annotation(com.org.example.annotations.AnnotationLogger)")
    public void logAdviceExecutionBefore(JoinPoint joinPoint){  
        CodeSignature codeSignature = (CodeSignature) joinPoint.getSignature();
        AnnotationLogger annotationLogger = getAnnotationLogger(joinPoint);
        if(annotationLogger!= null) {
            StringBuilder annotationLoggerFormat = new StringBuilder();
            List<Object> annotationLoggerArguments = new ArrayList<>();
            annotationLoggerFormat.append(METHOD_NAME);
            annotationLoggerArguments.add(codeSignature.getName());
            
            if (annotationLogger.showArguments()) {
                annotationLoggerFormat.append(ARGUMENTS);
                List<?> argumentList = Arrays.asList(joinPoint.getArgs());
                annotationLoggerArguments.add(argumentList.toString());
            }
            logger.error(annotationLoggerFormat.toString(), annotationLoggerArguments.toArray());
        }
    }
    
    private AnnotationLogger getAnnotationLogger(JoinPoint joinPoint) {
        AnnotationLogger annotationLogger = null;
        try {
            MethodSignature signature = (MethodSignature) joinPoint.getSignature();
            Method method = joinPoint.getTarget().getClass().
                    getMethod(signature.getMethod().getName(), signature.getMethod().getParameterTypes());
            
            if (method.isAnnotationPresent(AnnotationLogger.class)){
                annotationLogger = method.getAnnotation(AnnotationLoggerAspect.class);
            }else if (joinPoint.getTarget().getClass().isAnnotationPresent(AnnotationLoggerAspect.class)){
                annotationLogger = joinPoint.getTarget().getClass().getAnnotation(AnnotationLoggerAspect.class);
            }
            return annotationLogger;
        }catch(Exception e) {
            return annotationLogger;
        }
    }

What are valid values for the id attribute in HTML?
ID's cannot start with digits!!!

I have tried everything, and finally deleting the -vm options worked for me.

Alternatively you can have your class implement the InitializingBean interface to provide a callback function (afterPropertiesSet()) which the ApplicationContext will invoke when the bean is constructed.

If you put [FromBody] annotation and you have a Dto object as a parameter to your method and still not able to get the data through, start looking into the properties and fields of your DTO.

I had this same problem, where my DTO was coming null. I found the reason was that one of the properties was pointing into an object that cannot be serialised :( which causes the media-formatter to fail to parse the data. Thus the object was always null. Hope it helps others too

It is pretty easy to add a collaborator to a free plan.

1. Navigate to the repository on Github you wish to share with your collaborator.
2. Click on the "Settings" tab on the right side of the menu at the top of the screen.
3. On the new page, click the "Collaborators" menu item on the left side of the page.
4. Start typing the new collaborator's GitHub username into the text box.
5. Select the GitHub user from the list that appears below the text box.
6. Click the "Add" button.

The added user should now be able to push to your repository on GitHub.

You can select directly into the variable rather than using set:

DECLARE @times int

SELECT @times = COUNT(DidWin)
FROM thetable
WHERE DidWin = 1 AND Playername='Me'

If you need to set multiple variables you can do it from the same select (example a bit contrived):

DECLARE @wins int, @losses int

SELECT @wins = SUM(DidWin), @losses = SUM(DidLose)
FROM thetable
WHERE Playername='Me'

If you are partial to using set, you can use parentheses:

DECLARE @wins int, @losses int

SET (@wins, @losses) = (SELECT SUM(DidWin), SUM(DidLose)
FROM thetable
WHERE Playername='Me');

You can do this as follows:

for (Direction direction : EnumSet.allOf(Direction.class)) {
  // do stuff
}

The way I resolved it is by using Fragments. These are backwards compatible until API 4 by using the support library.

You make a "wrapper" layout with a FrameLayout in it.

Example:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
     android:layout_width="match_parent"
     android:layout_height="match_parent"
     android:orientation="vertical" >

     <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
          android:id="@+id/fragment_container"
          android:layout_width="match_parent"
          android:layout_height="match_parent" />
</LinearLayout>

Then you make a FragmentActivity in wich you can replace the FrameLayout any time you want.

Example:

public class SampleFragmentActivity extends FragmentActivity
{

     @Override
 public void onCreate(Bundle savedInstanceState)
 {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.wrapper);

    // Check that the activity is using the layout version with
    // the fragment_container FrameLayout
    if (findViewById(R.id.fragment_container) != null)
    {

        // However, if we're being restored from a previous state,
        // then we don't need to do anything and should return or else
        // we could end up with overlapping fragments.
        if (savedInstanceState != null)
        {
            return;
        }
        updateLayout();
     }
  }

  private void updateLayout()
  {
     Fragment fragment = new SampleFragment();
     fragment.setArguments(getIntent().getExtras());

     // replace original fragment by new fragment
     getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container, fragment).commit();
  }

In the Fragment you inflate/replace you can use the onStart and onCreateView like you normaly would use the onCreate of an activity.

Example:

public class SampleFragment extends Fragment
{

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
    {
        return inflater.inflate(R.layout.yourActualLayout, container, false);
    }

    @Override
    public void onStart()
    {
        // do something with the components, or not!
        TextView text = (TextView) getActivity().findViewById(R.id.text1);

        super.onStart();
    }
}

If you want to get all those information, you might want to read this:
http://php.net/manual/en/function.get-browser.php

You can run the sample code and you'll see how it works:

<?php
echo $_SERVER['HTTP_USER_AGENT'] . "\n\n";

$browser = get_browser(null, true);
print_r($browser);
?>

The above example will output something similar to:

Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7) Gecko/20040803 Firefox/0.9.3

Array

    [browser_name_regex] => ^mozilla/5\.0 (windows; .; windows nt 5\.1; .*rv:.*) gecko/.* firefox/0\.9.*$

Not jQuery, but it works well for a calendar with time: JavaScript Date Time Picker.

I just bound the click event to pop it up:

$(".arrival-date").click(function() {
    NewCssCal($(this).attr('id'), 'mmddyyyy', 'dropdown', true, 12);
});

This sometimes happens with Excel when you've recently used "Text to Columns."

Try exiting out of excel, reopening, and pasting again. That usually works for me, but I've heard you sometimes have to restart your computer altogether.

To filter a list of dicts you can use the selectattr filter together with the equalto test:

network.addresses.private_man | selectattr("type", "equalto", "fixed")

The above requires Jinja2 v2.8 or later (regardless of Ansible version).

Ansible also has the tests match and search, which take regular expressions:

match will require a complete match in the string, while search will require a match inside of the string.

network.addresses.private_man | selectattr("type", "match", "^fixed$")

To reduce the list of dicts to a list of strings, so you only get a list of the addr fields, you can use the map filter:

... | map(attribute='addr') | list

Or if you want a comma separated string:

... | map(attribute='addr') | join(',')

Combined, it would look like this.

- debug: msg={{ network.addresses.private_man | selectattr("type", "equalto", "fixed") | map(attribute='addr') | join(',') }}

You could use a Filter and do the following test:

HttpSession session = request.getSession(false);// don't create if it doesn't exist
if(session != null && !session.isNew()) {
    chain.doFilter(request, response);
} else {
    response.sendRedirect("/login.jsp");
}

The above code is untested.

This isn't the most extensive solution however. You should also test that some domain-specific object or flag is available in the session before assuming that because a session isn't new the user must've logged in. Be paranoid!

From the documentation , the function mysqli_real_escape_string() has two parameters.

string mysqli_real_escape_string ( mysqli $link , string $escapestr ).

The first one is a link for a mysqli instance (database connection object), the second one is the string to escape. So your code should be like :

$username = mysqli_real_escape_string($yourconnectionobject,$_POST['username']);

You can't, Print Preview is a feature of a browser, and therefore should be protected from being called by JavaScript as it would be a security risk.

That's why your example uses Active X, which bypasses the JavaScript security issues.

So instead use the print stylesheet that you already should have and show it for media=screen,print instead of media=print.

Read Alist Apart: Going to Print for a good article on the subject of print stylesheets.

Try the onbeforeunload event: It is fired just before the page is unloaded. It also allows you to ask back if the user really wants to leave. See the demo onbeforeunload Demo.

Alternatively, you can send out an Ajax request when he leaves.

Disclaimer: I am the author of Jsonix, a powerful open-source XML<->JSON JavaScript mapping library.

Today I've released the new version of the Jsonix Schema Compiler, with the new JSON Schema generation feature.

Let's take the Purchase Order schema for example. Here's a fragment:

  <xsd:element name="purchaseOrder" type="PurchaseOrderType"/>

  <xsd:complexType name="PurchaseOrderType">
    <xsd:sequence>
      <xsd:element name="shipTo" type="USAddress"/>
      <xsd:element name="billTo" type="USAddress"/>
      <xsd:element ref="comment" minOccurs="0"/>
      <xsd:element name="items"  type="Items"/>
    </xsd:sequence>
    <xsd:attribute name="orderDate" type="xsd:date"/>
  </xsd:complexType>

You can compile this schema using the provided command-line tool:

java -jar jsonix-schema-compiler-full.jar
    -generateJsonSchema
    -p PO
    schemas/purchaseorder.xsd

The compiler generates Jsonix mappings as well the matching JSON Schema.

Here's what the result looks like (edited for brevity):

{
    "id":"PurchaseOrder.jsonschema#",
    "definitions":{
        "PurchaseOrderType":{
            "type":"object",
            "title":"PurchaseOrderType",
            "properties":{
                "shipTo":{
                    "title":"shipTo",
                    "allOf":[
                        {
                            "$ref":"#/definitions/USAddress"
                        }
                    ]
                },
                "billTo":{
                    "title":"billTo",
                    "allOf":[
                        {
                            "$ref":"#/definitions/USAddress"
                        }
                    ]
                }, ...
            }
        },
        "USAddress":{ ... }, ...
    },
    "anyOf":[
        {
            "type":"object",
            "properties":{
                "name":{
                    "$ref":"http://www.jsonix.org/jsonschemas/w3c/2001/XMLSchema.jsonschema#/definitions/QName"
                },
                "value":{
                    "$ref":"#/definitions/PurchaseOrderType"
                }
            },
            "elementName":{
                "localPart":"purchaseOrder",
                "namespaceURI":""
            }
        }
    ]
}

Now this JSON Schema is derived from the original XML Schema. It is not exactly 1:1 transformation, but very very close.

The generated JSON Schema matches the generatd Jsonix mappings. So if you use Jsonix for XML<->JSON conversion, you should be able to validate JSON with the generated JSON Schema. It also contains all the required metadata from the originating XML Schema (like element, attribute and type names).

Disclaimer: At the moment this is a new and experimental feature. There are certain known limitations and missing functionality. But I'm expecting this to manifest and mature very fast.

I know this is old but here's a one liner list comprehension:

data = ['word1, 23, 12','word2, 10, 19','word3, 11, 15']

[[int(item) if item.isdigit() else item for item in items.split(', ')] for items in data]

or

[int(item) if item.isdigit() else item for items in data for item in items.split(', ')]

I'm using simple BASH script for renaming.

Usage: ./rename.sh oldName newName

#!/bin/sh

OLDNAME=$1
NEWNAME=$2

export LC_CTYPE=C 
export LANG=C
find . -type f ! -path ".*/.*" -exec sed -i '' -e "s/${OLDNAME}/${NEWNAME}/g" {} +

mv "${OLDNAME}.xcodeproj" "${NEWNAME}.xcodeproj"
mv "${OLDNAME}" "${NEWNAME}"

Notes:

1. This script will ignore all files like .git and .DS_Store
2. Will not work if old name/new name contains spaces
3. May not work if you use pods (not tested)
4. Scheme name will not be changed (anyway project runs and compiles normally)

SELECT  p.LastName, p.FirstName, o.OrderNo
FROM    persons AS p
LEFT JOIN
        orders AS o
ON      o.orderNo = p.p_id
UNION ALL
SELECT  NULL, NULL, orderNo
FROM    orders
WHERE   orderNo NOT IN
        (
        SELECT  p_id
        FROM    persons
        )

Install Aptana plugin to your Eclipse installation.

It has built-in FTP support, and it works excellently.

You can:

• Edit files directly from the FTP server
• Perform file/folder management (copy, delete, move, rename, etc.)
• Upload/download files to/from FTP server
• Synchronize local files with FTP server. You can make several profiles (actually projects) for this so you won't have to reinput over and over again.

As a matter of fact the FTP support is so good I'm using Aptana (or Eclipse + Aptana) now for all my FTP needs. Plus I get syntax highlighting/whatever coding support there is. Granted, Eclipse is not the speediest app to launch, but it doesn't bug me so much.

In my case, I use in component file:

import {formatDate} from '@angular/common';

// Use your preferred locale
import localeFr from '@angular/common/locales/fr';
import { registerLocaleData } from '@angular/common';

// ....

displayDate: string;
registerLocaleData(localeFr, 'fr');
this.displayDate = formatDate(new Date(), 'EEEE d MMMM yyyy', 'fr');

And in the component HTML file

<h1> {{ displayDate }} </h1>

It works fine for me ;-)

@AHegde - To get the tab delimited output use separator sep='\t'.

For df.to_csv:

df.to_csv(r'c:\data\pandas.txt', header=None, index=None, sep='\t', mode='a')

For np.savetxt:

np.savetxt(r'c:\data\np.txt', df.values, fmt='%d', delimiter='\t')

Maven is packaged for Fedora since mid 2014, so it is now pretty easy. Just type

sudo dnf install maven

Now test the installation, just run maven in a random directory

mvn

And it will fail, because you did not specify a goal, e.g. mvn package

I think your particular problem isn't how to use Glyphicons but understanding how Bootstrap files work together.

Bootstrap requires a specific file structure to work. I see from your code you have this:

<link href="bootstrap.css" rel="stylesheet" media="screen">

Your Bootstrap.css is being loaded from the same location as your page, this would create a problem if you didn't adjust your file structure.

But first, let me recommend you setup your folder structure like so:

/css      <-- Bootstrap.css here
/fonts    <-- Bootstrap fonts here
/img
/js       <-- Bootstrap JavaScript here
index.html

If you notice, this is also how Bootstrap structures its files in its download ZIP.

You then include your Bootstrap file like so:

<link href="css/bootstrap.css" rel="stylesheet" media="screen">
or
<link href="./css/bootstrap.css" rel="stylesheet" media="screen">
or
<link href="/css/bootstrap.css" rel="stylesheet" media="screen">

Depending on your server structure or what you're going for.

The first and second are relative to your file's current directory. The second one is just more explicit by saying "here" (./) first then css folder (/css).

The third is good if you're running a web server, and you can just use relative to root notation as the leading "/" will be always start at the root folder.

So, why do this?

Bootstrap.css has this specific line for Glyphfonts:

@font-face {
    font-family: 'Glyphicons Halflings';
    src: url('../fonts/glyphicons-halflings-regular.eot');
    src: url('../fonts/glyphicons-halflings-regular.eot?#iefix') format('embedded-opentype'), url('../fonts/glyphicons-halflings-regular.woff') format('woff'), url('../fonts/glyphicons-halflings-regular.ttf') format('truetype'), url('../fonts/glyphicons-halflings-regular.svg#glyphicons-halflingsregular') format('svg');
}

What you can see is that that Glyphfonts are loaded by going up one directory ../ and then looking for a folder called /fonts and THEN loading the font file.

The URL address is relative to the location of the CSS file. So, if your CSS file is at the same location like this:

/fonts
Bootstrap.css
index.html

The CSS file is going one level deeper than looking for a /fonts folder.

So, let's say the actual location of these files are:

C:\www\fonts
C:\www\Boostrap.css
C:\www\index.html

The CSS file would technically be looking for a folder at:

C:\fonts

but your folder is actually in:

C:\www\fonts

So see if that helps. You don't have to do anything 'special' to load Bootstrap Glyphicons, except make sure your folder structure is set up appropriately.

When you get that fixed, your HTML should simply be:

<span class="glyphicon glyphicon-comment"></span>

Note, you need both classes. The first class glyphicon sets up the basic styles while glyphicon-comment sets the specific image.

You can do it in O(n + kn) = O(n) (for constant k) for time and O(k) for space, by keeping track of the k largest elements you've seen.

For each element in the array you can scan the list of k largest and replace the smallest element with the new one if it is bigger.

Warren's priority heap solution is neater though.

In my case this works fine:

from pyspark_llap import HiveWarehouseSession
hive = HiveWarehouseSession.session(spark).build()
hive.setDatabase("DatabaseName")
df = spark.read.format("csv").option("Header",True).load("/user/csvlocation.csv")
df.write.format(HiveWarehouseSession().HIVE_WAREHOUSE_CONNECTOR).option("table",<tablename>).save()

Done!!

You can read the Data, let you give as "Employee"

hive.executeQuery("select * from Employee").show()

As per your question, I understand that you need to display some conditional data in Component 3 which is based on state of Component 5. Approach :

1. State of Component 3 will hold a variable to check whether Component 5's state has that data
2. Arrow Function which will change Component 3's state variable.
3. Passing arrow function to Component 5 with props.
4. Component 5 has an arrow function which will change Component 3's state variable
5. Arrow function of Component 5 called on loading itself

Class Component3 extends React.Component {
    state = {
        someData = true
    }

    checkForData = (result) => {
        this.setState({someData : result})
    }

    render() {
        if(this.state.someData) {
            return(
                <Component5 hasData = {this.checkForData} />
                //Other Data
            );
        }
        else {
            return(
                //Other Data
            );
        }
    }
}

export default Component3;

class Component5 extends React.Component {
    state = {
        dataValue = "XYZ"
    }
    checkForData = () => {
        if(this.state.dataValue === "XYZ") {
            this.props.hasData(true);
        }
        else {
            this.props.hasData(false);
        }
    }
    render() {
        return(
            <div onLoad = {this.checkForData}>
                //Conditional Data
            </div>
        );
    }
}
export default Component5;

If you get code behind, use some like this

        MyCustomObject myObject = new MyCustomObject();
        myObject.name='try';
        //OBJECT -> JSON
        var javaScriptSerializer = new System.Web.Script.Serialization.JavaScriptSerializer();
        string myObjectJson = javaScriptSerializer.Serialize(myObject);
        //return JSON   
        Response.Clear();     
        Response.ContentType = "application/json; charset=utf-8";
        Response.Write(myObjectJson );
        Response.End();

So you return a json object serialized with all attributes of MyCustomObject.
