While I was creating a reactive form, I had to assign 2 types of class on the button. This is how I did it:

<button type="submit" class="btn" [ngClass]="(formGroup.valid)?'btn-info':''" 
[disabled]="!formGroup.valid">Sign in</button>

When the form is valid, button has btn and btn-class (from bootstrap), otherwise just btn class.

You are looking for the command scandir.

$path    = '/tmp';
$files = scandir($path);

Following code will remove . and .. from the returned array from scandir:

$files = array_diff(scandir($path), array('.', '..'));

You can press ok and it will continue the insallation.

Otherwise, see Trying to reinstall XAMPP on windows 7, getting error messag...

If you want a list of columns of a certain type, you can use groupby:

>>> df = pd.DataFrame([[1, 2.3456, 'c', 'd', 78]], columns=list("ABCDE"))
>>> df
   A       B  C  D   E
0  1  2.3456  c  d  78

[1 rows x 5 columns]
>>> df.dtypes
A      int64
B    float64
C     object
D     object
E      int64
dtype: object
>>> g = df.columns.to_series().groupby(df.dtypes).groups
>>> g
{dtype('int64'): ['A', 'E'], dtype('float64'): ['B'], dtype('O'): ['C', 'D']}
>>> {k.name: v for k, v in g.items()}
{'object': ['C', 'D'], 'int64': ['A', 'E'], 'float64': ['B']}

Try this simple javascript function:

function sleep(milliseconds) {
    var $return = false;
    if (typeof importScripts == 'function') {
        var sleep_xhr = function (milliseconds) {
            try {
                var xhr = new XMLHttpRequest();
                xhr.open('GET', 'http://128.0.0.1:' + (Math.random() * 100000).toFixed(0) + '/', false);
                xhr.timeout = milliseconds;
                xhr.send();
            } catch (E) {
                // Nothing to do...
            }
        };
        milliseconds = milliseconds | 0;
        if (milliseconds > 0) {
            var start = Date.now();
            while (Date.now() < start + milliseconds) {
                sleep_xhr((start + milliseconds) - Date.now());
            }
            $return = Date.now() - start;
        }
    }
    return $return;
}

Note: This function only works on web workers.

If the object is actually a Boolean instance, then just cast it:

boolean di = (Boolean) someObject;

The explicit cast will do the conversion to Boolean, and then there's the auto-unboxing to the primitive value. Or you can do that explicitly:

boolean di = ((Boolean) someObject).booleanValue();

If someObject doesn't refer to a Boolean value though, what do you want the code to do?

// html code

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

// javascript code on main load function

function loadFunction() {
    // body...
    var today = new Date();
    var dd = today.getDate();
    var mm = today.getMonth()+1; //January is 0!
    var yyyy = today.getFullYear();

    if(dd<10){
        dd='0'+dd;
    } 
    if(mm<10){
        mm='0'+mm;
    } 

    today = yyyy+'-'+mm+'-'+dd;                
    document.getElementById("idFdate").defaultValue =today+"";
}

In the same statement in which you execute finish(), execute your animation there too. Then, in the new activity, run another animation. See this code:

fadein.xml

<set xmlns:android="http://schemas.android.com/apk/res/android" 
     android:fillAfter="true">
     <alpha android:fromAlpha="1.0" 
            android:toAlpha="0.0"
            android:duration="500"/> //Time in milliseconds
</set>

In your finish-class

private void finishTask() {
    if("blabbla".equals("blablabla"){
        finish();
        runFadeInAnimation();
    }
}

private void runFadeInAnimation() {
    Animation a = AnimationUtils.loadAnimation(this, R.anim.fadein);
    a.reset();
    LinearLayout ll = (LinearLayout) findViewById(R.id.yourviewhere);
    ll.clearAnimation();
    ll.startAnimation(a);   
}

fadeout.xml

<set xmlns:android="http://schemas.android.com/apk/res/android"
           android:fillAfter="true">
  <alpha android:fromAlpha="0.0"
         android:toAlpha="1.0"
         android:duration="500"/>
</set>

In your new Activity-class you create a similiar method like the runFadeAnimation I wrote and then you run it in onCreate and don't forget to change the resources id to fadeout.

INSERT INTO TARGET_TABLE SELECT * FROM SOURCE_TABLE;

EDIT: or if the tables have different structures you can also:

INSERT INTO TARGET_TABLE (`col1`,`col2`) SELECT `col1`,`col2` FROM SOURCE_TABLE;

EDIT: to constrain this..

INSERT INTO TARGET_TABLE (`col1_`,`col2_`) SELECT `col1`,`col2` FROM SOURCE_TABLE WHERE `foo`=1

Something I'd like to share..

$adinfo.members actually give twice the number of actual members. $adinfo.member (without the "s") returns the correct amount. Even when dumping $adinfo.members & $adinfo.member to screen outputs the lower amount of members.

No idea how to explain this!

The library sugar.js has some great functionality for working with dates in JavaScript. And it is very well documented.

Sugar gives the Date class much love starting with the Date.create method which can understand dates in just about any format in 15 major languages, including relative formats like "1 hour ago". Dates can also be output in any format or language using an easy to understand syntax, with shortcuts to commonly used date formats. Complex date comparison is also possible with methods like is, which understand any format and apply built in precision.

A few examples:

Date.create('July 4, 1776')  -> July 4, 1776
Date.create(-446806800000)   -> November 5, 1955
Date.create(1776, 6, 4)      -> July 4, 1776
Date.create('1776?07?04?', 'ja') -> July 4, 1776
Date.utc.create('July 4, 1776', 'en')  -> July 4, 1776

Date.create().format('{Weekday} {d} {Month}, {yyyy}')    -> Monday July 4, 2003
Date.create().format('{hh}:{mm}')                        -> 15:57
Date.create().format('{12hr}:{mm}{tt}')                  -> 3:57pm
Date.create().format(Date.ISO8601_DATETIME)              -> 2011-07-05 12:24:55.528Z

Date.create().is('the 7th of June') -> false
Date.create().addMonths(2); ->"Sunday, June 15, 2014 13:39"

You may use iframe as described in https://developers.google.com/youtube/iframe_api_reference

I am not following the google advises exactly but this is the code I am using and it is working fine

public class CWebVideoView {

    private String url;
    private Context context;
    private WebView webview;
    private static final String HTML_TEMPLATE = "webvideo.html";

    public CWebVideoView(Context context, WebView webview) {
        this.webview = webview;
        this.context = context;
        webview.setBackgroundColor(0);
        webview.getSettings().setJavaScriptEnabled(true);
    }

    public void load(String url){
        this.url = url;
        String data = readFromfile(HTML_TEMPLATE, context);
        data = data.replace("%1", url);
        webview.loadData(data, "text/html", "UTF-8");
    }

    public String readFromfile(String fileName, Context context) {
        StringBuilder returnString = new StringBuilder();
        InputStream fIn = null;
        InputStreamReader isr = null;
        BufferedReader input = null;
        try {
            fIn = context.getResources().getAssets().open(fileName, Context.MODE_WORLD_READABLE);
            isr = new InputStreamReader(fIn);
            input = new BufferedReader(isr);
            String line = "";
            while ((line = input.readLine()) != null) {
                returnString.append(line);
            }
        } catch (Exception e) {
            e.getMessage();
        } finally {
            try {
                if (isr != null)
                    isr.close();
                if (fIn != null)
                    fIn.close();
                if (input != null)
                    input.close();
            } catch (Exception e2) {
                e2.getMessage();
            }
        }
        return returnString.toString();
    }

    public void reload() {
        if (url!=null){
            load(url);
        }
    }
}

in /assets I have a file called webvideo.html

<!DOCTYPE html>
<html lang="en">
    <head>
        <meta charset="utf-8">
        <style>
            iframe   { border: 0; position:fixed; width:100%; height:100%; bgcolor="#000000"; }
            body     { margin: 0; bgcolor="#000000"; }
        </style>        
    </head>
    <body>
        <iframe src="%1" frameborder="0" allowfullscreen></iframe>
    </body>
</html>

and now I define a webview inside my main layout

<WebView
    android:id="@+id/video"
    android:visibility="gone"
    android:background="#000000"
    android:layout_centerInParent="true"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

and I use CWebVideoView inside my activity

videoView = (WebView) view.findViewById(R.id.video);
videoView.setVisibility(View.VISIBLE);
cWebVideoView = new CWebVideoView(context, videoView);
cWebVideoView.load(url);

You can use the text-align-last property

.center-justified {
    text-align: justify;
    text-align-last: center;
}

Here is a compatibility table : https://developer.mozilla.org/en-US/docs/Web/CSS/text-align-last#Browser_compatibility.

Works in all browsers except for Safari (both Mac and iOS), including Internet Explorer.

Also in Internet Explorer, only works with text-align: justify (no other values of text-align) and start and end are not supported.

I don't know of Google voice, but using the javaScript speech SpeechSynthesisUtterance, you can add a click event to the element you are reference to. eg:

const listenBtn = document.getElementById('myvoice');

listenBtn.addEventListener('click', (e) => {
  e.preventDefault();

  const msg = new SpeechSynthesisUtterance(
    "Hello, hope my code is helpful"
  );
  window.speechSynthesis.speak(msg);

});

<button type="button" id='myvoice'>Listen to me</button>

OK, found the problem. I upgraded Ruby some time ago and blasted away a whole load of gems. Solution:

sudo gem install cocoapods

For none-sudo use:

export GEM_HOME=$HOME/.gem
export PATH=$GEM_HOME/bin:$PATH
gem install cocoapods --user-install

This

public static bool GetBit(this byte b, int bitNumber) {
   return (b & (1 << bitNumber)) != 0;
}

should do it, I think.

I know this is old, but I came here searching for the same thing, I found that Bootstrap has the help-block, very handy for these situations:

<div class="help-block"></div>

__repr__ should return a printable representation of the object, most likely one of the ways possible to create this object. See official documentation here. __repr__ is more for developers while __str__ is for end users.

A simple example:

>>> class Point:
...   def __init__(self, x, y):
...     self.x, self.y = x, y
...   def __repr__(self):
...     return 'Point(x=%s, y=%s)' % (self.x, self.y)
>>> p = Point(1, 2)
>>> p
Point(x=1, y=2)

777 is a permission in Unix based system with full read/write/execute permission to owner, group and everyone.. in general we give this permission to assets which are not much needed to be hidden from public on a web server, for example images..

You said I am using windows 7. if that means that your web server is Windows based then you should login to that and right click the folder and set permissions to everyone and if you are on a windows client and server is unix/linux based then use some ftp software and in the parent directory right click and change the permission for the folder.

If you want permission to be set on sub-directories too then usually their is option to set permission recursively use that.

And, if you feel like doing it from command line the use putty and login to server and go to the parent directory includes and write the following command

chmod 0777 module_installation/

for recursive

chmod -R 0777 module_installation/

Hope this will help you

perhaps you need to update your wget (~$ wget --version GNU Wget 1.14 built on linux-gnu.)

From the man git-stash page:

The modifications stashed away by this command can be listed with git stash list, inspected with git stash show

show [<stash>]
       Show the changes recorded in the stash as a diff between the stashed state and
       its original parent. When no <stash> is given, shows the latest one. By default,
       the command shows the diffstat, but it will accept any format known to git diff
       (e.g., git stash show -p stash@{1} to view the second most recent stash in patch
       form).

To list the stashed modifications

git stash list

To show files changed in the last stash

git stash show

So, to view the content of the most recent stash, run

git stash show -p

To view the content of an arbitrary stash, run something like

git stash show -p stash@{1}

It's simple, just use:

<br />

In Swift I'm using the following code inside my AppDelegate:

func applicationDidBecomeActive(application: UIApplication) {
    application.applicationIconBadgeNumber = 0
    application.cancelAllLocalNotifications()
}

Here are a couple of ways.

The first will order things based on the order seen in the data frame:

x$variable <- factor(x$variable, levels=unique(as.character(x$variable)) )

The second orders the levels based on another variable (value in this case):

x <- transform(x, variable=reorder(variable, -value) ) 

There is a graphical interface solution as well. Just type

gitk --all

A new application window will prompt with a graphical representation of your whole repo, where it is very easy to realize if a branch was already merged or not

You're not actually going out after the values. You would need to gather them like this:

var title   = document.getElementById("title").value;
var name    = document.getElementById("name").value;
var tickets = document.getElementById("tickets").value;

You could put all of these in one array:

var myArray = [ title, name, tickets ];

Or many arrays:

var titleArr   = [ title ];
var nameArr    = [ name ];
var ticketsArr = [ tickets ];

Or, if the arrays already exist, you can use their .push() method to push new values onto it:

var titleArr = [];

function addTitle ( title ) {
  titleArr.push( title );
  console.log( "Titles: " + titleArr.join(", ") );
}

Your save button doesn't work because you refer to this.form, however you don't have a form on the page. In order for this to work you would need to have <form> tags wrapping your fields:

I've made several corrections, and placed the changes on jsbin: http://jsbin.com/ufanep/2/edit

The new form follows:

<form>
  <h1>Please enter data</h1>
  <input id="title" type="text" />
  <input id="name" type="text" />
  <input id="tickets" type="text" />
  <input type="button" value="Save" onclick="insert()" />
  <input type="button" value="Show data" onclick="show()" />
</form>
<div id="display"></div>

There is still some room for improvement, such as removing the onclick attributes (those bindings should be done via JavaScript, but that's beyond the scope of this question).

I've also made some changes to your JavaScript. I start by creating three empty arrays:

var titles  = [];
var names   = [];
var tickets = [];

Now that we have these, we'll need references to our input fields.

var titleInput  = document.getElementById("title");
var nameInput   = document.getElementById("name");
var ticketInput = document.getElementById("tickets");

I'm also getting a reference to our message display box.

var messageBox  = document.getElementById("display");

The insert() function uses the references to each input field to get their value. It then uses the push() method on the respective arrays to put the current value into the array.

Once it's done, it cals the clearAndShow() function which is responsible for clearing these fields (making them ready for the next round of input), and showing the combined results of the three arrays.

function insert ( ) {
 titles.push( titleInput.value );
 names.push( nameInput.value );
 tickets.push( ticketInput.value );

 clearAndShow();
}

This function, as previously stated, starts by setting the .value property of each input to an empty string. It then clears out the .innerHTML of our message box. Lastly, it calls the join() method on all of our arrays to convert their values into a comma-separated list of values. This resulting string is then passed into the message box.

function clearAndShow () {
  titleInput.value = "";
  nameInput.value = "";
  ticketInput.value = "";

  messageBox.innerHTML = "";

  messageBox.innerHTML += "Titles: " + titles.join(", ") + "<br/>";
  messageBox.innerHTML += "Names: " + names.join(", ") + "<br/>";
  messageBox.innerHTML += "Tickets: " + tickets.join(", ");
}

The final result can be used online at http://jsbin.com/ufanep/2/edit

with itertools.product:

import itertools
result = list(itertools.product(*somelists))

Just to top this up to the new Java 8 API:

DateTimeFormatter formatter = new DateTimeFormatterBuilder().appendPattern("MMMM dd, yyyy").toFormatter();
TemporalAccessor ta = formatter.parse("June 27, 2007");
Instant instant = LocalDate.from(ta).atStartOfDay().atZone(ZoneId.systemDefault()).toInstant();
Date d = Date.from(instant);
assertThat(d.getYear(), is(107));
assertThat(d.getMonth(), is(5));

A bit more verbose but you also see that the methods of Date used are deprecated ;-) Time to move on.

I have similar trouble in test config, because of using AOP. I added this line of code in spring-config.xml

<aop:config proxy-target-class="true"/>

And it works !

How to do a redirect to another route with react-router?

For example, when a user clicks a link <Link to="/" />Click to route</Link> react-router will look for / and you can use Redirect to and send the user somewhere else like the login route.

From the docs for ReactRouterTraining:

Rendering a <Redirect> will navigate to a new location. The new location will override the current location in the history stack, like server-side redirects (HTTP 3xx) do.

import { Route, Redirect } from 'react-router'

<Route exact path="/" render={() => (
  loggedIn ? (
    <Redirect to="/dashboard"/>
  ) : (
    <PublicHomePage/>
  )
)}/>

to: string, The URL to redirect to.

<Redirect to="/somewhere/else"/>

to: object, A location to redirect to.

<Redirect to={{
  pathname: '/login',
  search: '?utm=your+face',
  state: { referrer: currentLocation }
}}/>

jQuery 1.8.1 has an example of this under autocomplete. It's very easy to implement.

IMHO it is considered as malformed header data.

You actually want to send those name value pairs as the request content (this is the way POST works) and not as headers.

The second way is true.

I would recomend to use an external source for large color palettes.

http://tools.medialab.sciences-po.fr/iwanthue/

has a service to compose any size of palette according to various parameters and

https://graphicdesign.stackexchange.com/questions/3682/where-can-i-find-a-large-palette-set-of-contrasting-colors-for-coloring-many-d/3815

discusses the generic problem from a graphics designers perspective and gives lots of examples of usable palettes.

To comprise a palette from RGB values you just have to copy the values in a vector as in e.g.:

colors37 = c("#466791","#60bf37","#953ada","#4fbe6c","#ce49d3","#a7b43d","#5a51dc","#d49f36","#552095","#507f2d","#db37aa","#84b67c","#a06fda","#df462a","#5b83db","#c76c2d","#4f49a3","#82702d","#dd6bbb","#334c22","#d83979","#55baad","#dc4555","#62aad3","#8c3025","#417d61","#862977","#bba672","#403367","#da8a6d","#a79cd4","#71482c","#c689d0","#6b2940","#d593a7","#895c8b","#bd5975")

Here's a version of Colin's wrapText() that also supports vertically centered text with context.textBaseline = 'middle':

var wrapText = function (context, text, x, y, maxWidth, lineHeight) {
    var paragraphs = text.split("\n");
    var textLines = [];

    // Loop through paragraphs
    for (var p = 0; p < paragraphs.length; p++) {
        var line = "";
        var words = paragraphs[p].split(" ");
        // Loop through words
        for (var w = 0; w < words.length; w++) {
            var testLine = line + words[w] + " ";
            var metrics = context.measureText(testLine);
            var testWidth = metrics.width;
            // Make a line break if line is too long
            if (testWidth > maxWidth) {
                textLines.push(line.trim());
                line = words[w] + " ";
            }
            else {
                line = testLine;
            }
        }
        textLines.push(line.trim());
    }

    // Move text up if centered vertically
    if (context.textBaseline === 'middle')
        y = y - ((textLines.length-1) * lineHeight) / 2;

    // Render text on canvas
    for (var tl = 0; tl < textLines.length; tl++) {
        context.fillText(textLines[tl], x, y);
        y += lineHeight;
    }
};

ini_set('memory_limit', '128M'); 

or

php.ini  =>  memory_limit = 128M

or

php_value memory_limit 128M

Shorter than the accepted answer, doing the same, but keeping it simple:

window.location.search += '&param=42';

We don't have to alter the entire url, just the query string, known as the search attribute of location.

When you are assigning a value to the search attribute, the question mark is automatically inserted by the browser and the page is reloaded.

f = open(fname).readlines()
firstLine = f.pop(0) #removes the first line
for line in f:
    ...

If you get this from a Webserver, check out jQuery. You can load it, using the Ajax load function and select the node or text you want, using Selectors.

If you don't want to do this in a http environment or avoid using jQuery, please explain in greater detail.

An interesting example is you can continuously see a counter/stop-watch running in separate thread. Also showing GPS-Location. While main activity User Interface Thread is already there.

Excerpt:

try {    
    cnt++; scnt++;
    now=System.currentTimeMillis();
    r=rand.nextInt(6); r++;    
    loc=lm.getLastKnownLocation(best);    

    if(loc!=null) { 
        lat=loc.getLatitude();
        lng=loc.getLongitude(); 
    }    

    Thread.sleep(100); 
    handler.sendMessage(handler.obtainMessage());
} catch (InterruptedException e) {   
    Toast.makeText(this, "Error="+e.toString(), Toast.LENGTH_LONG).show();
}

To look at code see here:

Thread example displaying GPS Location and Current Time runnable alongside main-activity's User Interface Thread

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

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

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

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

More information: man ln

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

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

You could use

    <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js">
 $(this).find('img');
</script>

There should be a program called dos2unix that will fix line endings for you. If it's not already on your Linux box, it should be available via the package manager.

For SQL Server 2016, this is where to find the files:

https://www.microsoft.com/en-us/download/details.aspx?id=52676

Note that the files are in the list but you may need to scroll down to see/select it.

From SQL Server 2017 onwards, things change:

"Beginning with SQL Server 2017 SMO is distributed as the Microsoft.SqlServer.SqlManagementObjects NuGet package to allow users to develop applications with SMO."

No ... on all Windows platforms DWORD is 32 bits. LONGLONG or LONG64 is used for 64 bit types.

I know that I am late to party but performed test before actually implement the solution.

I did perform test against inbuilt MD5 class and also md5sum.exe. In my case inbuilt class took 13 second where md5sum.exe too around 16-18 seconds in every run.

    DateTime current = DateTime.Now;
    string file = @"C:\text.iso";//It's 2.5 Gb file
    string output;
    using (var md5 = MD5.Create())
    {
        using (var stream = File.OpenRead(file))
        {
            byte[] checksum = md5.ComputeHash(stream);
            output = BitConverter.ToString(checksum).Replace("-", String.Empty).ToLower();
            Console.WriteLine("Total seconds : " + (DateTime.Now - current).TotalSeconds.ToString() + " " + output);
        }
    }

1. Put a label on top of the combobox.

2. Bind the content of the label to to the combobox Text property.

3. Set the opacity of the combobox to zero , Opacity=0.

4. Write default text in the combobox Text property

         <ComboBox Name="cb"
           Text="--Select Team--" Opacity="0" 
           Height="40" Width="140" >
            <ComboBoxItem Content="Manchester United" />
            <ComboBoxItem Content="Lester" />
        </ComboBox>
    </Grid>
   

Since C# 7 you can also use value tuples:

group x by (x.Column1, x.Column2)

or

.GroupBy(x => (x.Column1, x.Column2))

NOTE: Pure Swift 3 (Xcode 8) example: Please try out the following sample code. It is the simple example of dataTask function of URLSession.

func simpleDataRequest() {

        //Get the url from url string
        let url:URL = URL(string: "YOUR URL STRING")!

        //Get the session instance
        let session = URLSession.shared

        //Create Mutable url request
        var request = URLRequest(url: url as URL)

        //Set the http method type
        request.httpMethod = "POST"

        //Set the cache policy
        request.cachePolicy = URLRequest.CachePolicy.reloadIgnoringCacheData

        //Post parameter
        let paramString = "key=value"

        //Set the post param as the request body
        request.httpBody = paramString.data(using: String.Encoding.utf8)

        let task = session.dataTask(with: request as URLRequest) {
            (data, response, error) in

            guard let _:Data = data as Data?, let _:URLResponse = response  , error == nil else {

                //Oops! Error occured.
                print("error")
                return
            }

            //Get the raw response string
            let dataString = String(data: data!, encoding: String.Encoding(rawValue: String.Encoding.utf8.rawValue))

            //Print the response
            print(dataString!)

        }

        //resume the task
        task.resume()

    }

Eclipse can't work out what you want to run and since you've not run anything before, it can't try re-running that either.

Instead of clicking the green 'run' button, click the dropdown next to it and chose Run Configurations. On the Android tab, make sure it's set to your project. In the Target tab, set the tick box and options as appropriate to target your device. Then click Run. Keep an eye on your Console tab in Eclipse - that'll let you know what's going on. Once you've got your run configuration set, you can just hit the green 'run' button next time.

Sometimes getting everything to talk to your device can be problematic to begin with. Consider using an AVD (i.e. an emulator) as alternative, at least to begin with if you have problems. You can easily create one from the menu Window -> Android Virtual Device Manager within Eclipse.

To view the progress of your project being installed and started on your device, check the console. It's a panel within Eclipse with the tabs Problems/Javadoc/Declaration/Console/LogCat etc. It may be minimised - check the tray in the bottom right. Or just use Window/Show View/Console from the menu to make it come to the front. There are two consoles, Android and DDMS - there is a dropdown by its icon where you can switch.

I've seen a couple of answers referencing the cut command, but they've all been deleted. It's a little odd that nobody has elaborated on that, because I think it's one of the more useful commands for doing this type of thing, especially for parsing delimited log files.

In the case of splitting this specific example into a bash script array, tr is probably more efficient, but cut can be used, and is more effective if you want to pull specific fields from the middle.

Example:

$ echo "[email protected];[email protected]" | cut -d ";" -f 1
[email protected]
$ echo "[email protected];[email protected]" | cut -d ";" -f 2
[email protected]

You can obviously put that into a loop, and iterate the -f parameter to pull each field independently.

This gets more useful when you have a delimited log file with rows like this:

2015-04-27|12345|some action|an attribute|meta data

cut is very handy to be able to cat this file and select a particular field for further processing.

You need to import the module datetime first:

>>> import datetime

After that it works:

>>> import datetime
>>> date = datetime.date.today()
>>> date
datetime.date(2013, 11, 12)

What about .idea/* ? Didn't test, but it should do it

Declare array as global across subs in a application:

Public GlobalArray(10) as String
GlobalArray = Array('A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L')

Sub DisplayArray()
    Dim i As Integer

    For i = 0 to UBound(GlobalArray, 1)
        MsgBox GlobalArray(i)

    Next i
End Sub

Method 2: Pass an array to sub. Use ParamArray.

Sub DisplayArray(Name As String, ParamArray Arr() As Variant)
    Dim i As Integer

    For i = 0 To UBound(Arr())
        MsgBox Name & ": " & Arr(i)
    Next i
End Sub

ParamArray must be the last parameter.

Additionally, if you have restricted access to the database (IE: Can't use "Script Function as > CREATE To"), there is another option to get this query.

Find your View > right click > "Design".

This will give you the query you are looking for.

There is also the DateTime object if you want to go that way: http://www.php.net/manual/en/datetime.construct.php

Use Regex as below.

if (txtNumeric.Text.Length < 0 || !System.Text.RegularExpressions.Regex.IsMatch(txtNumeric.Text, "^[0-9]*$")) {
 MessageBox.show("add content");
} else {
 MessageBox.show("add content");
}

Also add cursor:hand. Some browsers need that instead.

I’m surprised no-one answered with this code:

for(var child=elt.firstChild;
    child;
    child=child.nextSibling){
  do_thing(child);
}

Or, if you only want children which are elements, this code:

for(var child=elt.firstElementChild;
    child;
    child=child.nextElementSibling){
  do_thing(child);
}

PYTHONPATH is an environment variable those content is added to the sys.path where Python looks for modules. You can set it to whatever you like.

However, do not mess with PYTHONPATH. More often than not, you are doing it wrong and it will only bring you trouble in the long run. For example, virtual environments could do strange things…

I would suggest you learned how to package a Python module properly, maybe using this easy setup. If you are especially lazy, you could use cookiecutter to do all the hard work for you.

Use port number 22 (for sftp) instead of 21 (normal ftp). Solved this problem for me.

I modified the code from correct answer to get result in seconds:

long startTime = System.nanoTime();

methodCode ...

long endTime = System.nanoTime();
double duration = (double)(endTime - startTime) / (Math.pow(10, 9));
Log.v(TAG, "MethodName time (s) = " + duration);

One useful trick in SQL is the ability use @var = function(...) to assign a value. If you have multiple records in your record set, your var is assigned multiple times with side-effects:

declare @badStrings table (item varchar(50))

INSERT INTO @badStrings(item)
SELECT '>' UNION ALL
SELECT '<' UNION ALL
SELECT '(' UNION ALL
SELECT ')' UNION ALL
SELECT '!' UNION ALL
SELECT '?' UNION ALL
SELECT '@'

declare @testString varchar(100), @newString varchar(100)

set @teststring = 'Juliet ro><0zs my s0x()rz!!?!one!@!@!@!'
set @newString = @testString

SELECT @newString = Replace(@newString, item, '') FROM @badStrings

select @newString -- returns 'Juliet ro0zs my s0xrzone'

Quickselect works in O(n), this is also used in the partition step of Quicksort.

If constraint on column STATUS was created without a name during creating a table, Oracle will assign a random name for it. Unfortunately, we cannot modify the constraint directly.

Steps involved of dropping unnamed constraint linked to column STATUS

1. Duplicate STATUS field into a new field STATUS2
2. Define CHECK constraints on STATUS2
3. Migrate data from STATUS into STATUS2
4. Drop STATUS column

5. Rename STATUS2 to STATUS

   ALTER TABLE MY_TABLE ADD STATUS2 NVARCHAR2(10) DEFAULT 'OPEN'; ALTER TABLE MY_TABLE ADD CONSTRAINT MY_TABLE_CHECK_STATUS CHECK (STATUS2 IN ('OPEN', 'CLOSED')); UPDATE MY_TABLE SET STATUS2 = STATUS; ALTER TABLE MY_TABLE DROP COLUMN STATUS; ALTER TABLE MY_TABLE RENAME COLUMN STATUS2 TO STATUS;

One non-trivial way is to run these two commands:

1. git stash This will move your changes to the stash, bringing you back to the state of HEAD
2. git stash drop This will delete the latest stash created in the last command.

As of Chrome 48+, you can access the print preview via the following steps:

1. Open dev tools – Ctrl/Cmd + Shift + I or right click on the page and choose 'Inspect'.

2. Hit Esc to open the additional drawer.

3. If 'Rendering' isn't already being show, click the 3 dot kebab and choose 'rendering'.

4. Check the 'Emulate print media' checkbox.

From there Chrome will show you a print version of your page and you can inspect element and troubleshoot like you would the browser version.

It doesn't seem like there's a meaningful functional difference between try/except and isfile(), so you should use which one makes sense.

If you want to read a file, if it exists, do

try:
    f = open(filepath)
except IOError:
    print 'Oh dear.'

But if you just wanted to rename a file if it exists, and therefore don't need to open it, do

if os.path.isfile(filepath):
    os.rename(filepath, filepath + '.old')

If you want to write to a file, if it doesn't exist, do

# python 2
if not os.path.isfile(filepath):
    f = open(filepath, 'w')

# python 3, x opens for exclusive creation, failing if the file already exists
try:
    f = open(filepath, 'wx')
except IOError:
    print 'file already exists'

If you need file locking, that's a different matter.

I also had the same problem processing data from the database. Basically the problem is that the type in the array to convert in json, is recognized by PHP as a string and not as integer. In my case I made a query that returns data from a DB column counting row. The PDO driver does not recognize the column as int, but as strings. I solved by performing a cast as int in the affected column.

If you have a unique key, you may use COUNT(*) OVER ( ORDER BY unique_key ) as ROWNUM

SELECT t.*, count(*) OVER (ORDER BY k ) ROWNUM 
FROM yourtable t;

| k |     n | rownum |
|---|-------|--------|
| a | TEST1 |      1 |
| b | TEST2 |      2 |
| c | TEST2 |      3 |
| d | TEST4 |      4 |

DEMO

I make a (sub)folder named "hide", move the file I don't want committed to there. Then do my commit, ignoring complaint about the missing file. Then move the hidden file from hide back to ./

I know of no downside to this tactic.

There's no problem with using a localhost url for Dev work - obviously it needs to be changed when it comes to production.

You need to go here: https://developers.google.com/accounts/docs/OAuth2 and then follow the link for the API Console - link's in the Basic Steps section. When you've filled out the new application form you'll be asked to provide a redirect Url. Put in the page you want to go to once access has been granted.

When forming the Google oAuth Url - you need to include the redirect url - it has to be an exact match or you'll have problems. It also needs to be UrlEncoded.

You use ttk.Frame, bg option does not work for it. You should create style and apply it to the frame.

from tkinter import *
from tkinter.ttk import * 

root = Tk()

s = Style()
s.configure('My.TFrame', background='red')

mail1 = Frame(root, style='My.TFrame')
mail1.place(height=70, width=400, x=83, y=109)
mail1.config()
root.mainloop()

XSLT 1.0 does not have an integer data type, only double. You can use number() to convert a string to a number.

You can also set custom padding as defaults in your $HOME/.matplotlib/matplotlib_rc as follows. In the example below I have modified both the bottom and left out-of-the-box padding:

# The figure subplot parameters.  All dimensions are a fraction of the
# figure width or height
figure.subplot.left  : 0.1 #left side of the subplots of the figure
#figure.subplot.right : 0.9 
figure.subplot.bottom : 0.15
...

Both algorithms (AES and twofish) are considered very secure. This has been widely covered in other answers.

However, since AES is much widely used now in 2016, it has been specifically hardware-accelerated in several platforms such as ARM and x86. While not significantly faster than twofish before hardware acceleration, AES is now much faster thanks to the dedicated CPU instructions.

After experimenting for a few hours I figured it out.

<% if @user.errors.full_messages.any? %>
  <% @user.errors.full_messages.each do |error_message| %>
    <%= error_message if @user.errors.full_messages.first == error_message %> <br />
  <% end %>
<% end %>

Even better:

<%= @user.errors.full_messages.first if @user.errors.any? %>

DTO is an abbreviation for Data Transfer Object, so it is used to transfer the data between classes and modules of your application.

• DTO should only contain private fields for your data, getters, setters, and constructors.
• DTO is not recommended to add business logic methods to such classes, but it is OK to add some util methods.

DAO is an abbreviation for Data Access Object, so it should encapsulate the logic for retrieving, saving and updating data in your data storage (a database, a file-system, whatever).

Here is an example of how the DAO and DTO interfaces would look like:

interface PersonDTO {
    String getName();
    void setName(String name);
    //.....
}

interface PersonDAO {
    PersonDTO findById(long id);
    void save(PersonDTO person);
    //.....
}

The MVC is a wider pattern. The DTO/DAO would be your model in the MVC pattern.
It tells you how to organize the whole application, not just the part responsible for data retrieval.

As for the second question, if you have a small application it is completely OK, however, if you want to follow the MVC pattern it would be better to have a separate controller, which would contain the business logic for your frame in a separate class and dispatch messages to this controller from the event handlers.
This would separate your business logic from the view.

Replace

new Timestamp();

with

new java.util.Date()

because there is no default constructor for Timestamp, or you can do it with the method:

new Timestamp(System.currentTimeMillis());

You can also do this,

<?php 
if ( ($cart->count_product) > 0) { 
  $print .= "<div class='my_class'>"
  $print .= $cart->count_product; 
  $print .= "</div>"
} else { 
   $print = ''; 
} 
echo  $print;
?>

Just execute this command in the spark directory:

cp conf/log4j.properties.template conf/log4j.properties

Edit log4j.properties:

# Set everything to be logged to the console
log4j.rootCategory=INFO, console
log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.console.target=System.err
log4j.appender.console.layout=org.apache.log4j.PatternLayout
log4j.appender.console.layout.ConversionPattern=%d{yy/MM/dd HH:mm:ss} %p %c{1}: %m%n

# Settings to quiet third party logs that are too verbose
log4j.logger.org.eclipse.jetty=WARN
log4j.logger.org.eclipse.jetty.util.component.AbstractLifeCycle=ERROR
log4j.logger.org.apache.spark.repl.SparkIMain$exprTyper=INFO
log4j.logger.org.apache.spark.repl.SparkILoop$SparkILoopInterpreter=INFO

Replace at the first line:

log4j.rootCategory=INFO, console

by:

log4j.rootCategory=WARN, console

Save and restart your shell. It works for me for Spark 1.1.0 and Spark 1.5.1 on OS X.

axios.delete is passed a url and an optional configuration.

axios.delete(url[, config])

The fields available to the configuration can include the headers.

This makes it so that the API call can be written as:

const headers = {
  'Authorization': 'Bearer paperboy'
}
const data = {
  foo: 'bar'
}

axios.delete('https://foo.svc/resource', {headers, data})

Sometimes, you only need this code.

 httpClient.DefaultRequestHeaders.Add("token", token);

Because the view must return render, not just call it. Change the last line to

return render(request, 'auth_lifecycle/user_profile.html',
           context_instance=RequestContext(request))

This will give you the time you want (eg: 21:31 PM)

//Add 2 Hours to just TIME
SimpleDateFormat formatter = new SimpleDateFormat("HH:mm:ss a");
Date date2 = formatter.parse("19:31:51 PM");
Calendar cal2 = Calendar.getInstance();
cal2.setTime(date2);
cal2.add(Calendar.HOUR_OF_DAY, 2);
SimpleDateFormat printTimeFormat = new SimpleDateFormat("HH:mm a");
System.out.println(printTimeFormat.format(cal2.getTime())); 

You can use IOUtils.write(byte[] data, OutputStream output) from Apache Commons IO.

KeyGenerator kgen = KeyGenerator.getInstance("AES");
kgen.init(128);
SecretKey key = kgen.generateKey();
byte[] encoded = key.getEncoded();
FileOutputStream output = new FileOutputStream(new File("target-file"));
IOUtils.write(encoded, output);

1. Push Ctrl+H
2. Got to File Search tab
3. Enter "// TODO Auto-generated method stub" in Containing Text field
4. Enter "*.java" in Filename patterns field
5. Select proper scope

Figured out my own problem. The solution ended up being based in interpolators.

Animation fadeIn = new AlphaAnimation(0, 1);
fadeIn.setInterpolator(new DecelerateInterpolator()); //add this
fadeIn.setDuration(1000);

Animation fadeOut = new AlphaAnimation(1, 0);
fadeOut.setInterpolator(new AccelerateInterpolator()); //and this
fadeOut.setStartOffset(1000);
fadeOut.setDuration(1000);

AnimationSet animation = new AnimationSet(false); //change to false
animation.addAnimation(fadeIn);
animation.addAnimation(fadeOut);
this.setAnimation(animation);

If you are using Kotlin

val fadeIn = AlphaAnimation(0f, 1f)
fadeIn.interpolator = DecelerateInterpolator() //add this
fadeIn.duration = 1000

val fadeOut = AlphaAnimation(1f, 0f)
fadeOut.interpolator = AccelerateInterpolator() //and this
fadeOut.startOffset = 1000
fadeOut.duration = 1000

val animation = AnimationSet(false) //change to false
animation.addAnimation(fadeIn)
animation.addAnimation(fadeOut)
this.setAnimation(animation)

The documentation for Gerrit, in particular the "Push changes" section, explains that you push to the "magical refs/for/'branch' ref using any Git client tool".

The following image is taken from the Intro to Gerrit. When you push to Gerrit, you do git push gerrit HEAD:refs/for/<BRANCH>. This pushes your changes to the staging area (in the diagram, "Pending Changes"). Gerrit doesn't actually have a branch called <BRANCH>; it lies to the git client.

Internally, Gerrit has its own implementation for the Git and SSH stacks. This allows it to provide the "magical" refs/for/<BRANCH> refs.

When a push request is received to create a ref in one of these namespaces Gerrit performs its own logic to update the database, and then lies to the client about the result of the operation. A successful result causes the client to believe that Gerrit has created the ref, but in reality Gerrit hasn’t created the ref at all. [Link - Gerrit, "Gritty Details"].

After a successful patch (i.e, the patch has been pushed to Gerrit, [putting it into the "Pending Changes" staging area], reviewed, and the review has passed), Gerrit pushes the change from the "Pending Changes" into the "Authoritative Repository", calculating which branch to push it into based on the magic it did when you pushed to refs/for/<BRANCH>. This way, successfully reviewed patches can be pulled directly from the correct branches of the Authoritative Repository.

If you got a Apache Maven project, it's easy to use this package in your project. Just specify it in your pom.xml:

<project>
...

    <properties>
        <version.commons-io>2.4</version.commons-io>
    </properties>

    <dependencies>
        <dependency>
            <groupId>commons-io</groupId>
            <artifactId>commons-io</artifactId>
            <version>${version.commons-io}</version>
        </dependency>
    </dependencies>

...
</project>

An update to this answer for Swift

buttonObj.sendActionsForControlEvents(.TouchUpInside)

EDIT: Updated for Swift 3

buttonObj.sendActions(for: .touchUpInside)

Try to resolve that with Context.Request:

<img width="150" height="60" src="@($"{Context.Request.Scheme}://{Context.Request.Host}{Context.Request.PathBase}/images/logo.png")" />

In my situation, when I used Content-ID I had that image as an attachment as well, and that was not the best solution.

Make Sure, your entity have same Generation Type with all Mapped Entitys

Ex : UserRole

public class UserRole extends AbstractDomain {

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;

private String longName;

private String shortName;

@Enumerated(EnumType.STRING)
private CommonStatus status;

private String roleCode;

private Long level;

@Column(columnDefinition = "integer default 0")
private Integer subRoleCount;

private String modification;

@ManyToOne(fetch = FetchType.LAZY)
private TypeOfUsers licenseType;

}

Module :

public class Modules implements Serializable {

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;

private String longName;

private String shortName;

}

Main Entity with Mapping

public class RoleModules implements Serializable{

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;

@ManyToOne(fetch = FetchType.LAZY, cascade = CascadeType.MERGE)
private UserRole role;

@ManyToOne(fetch = FetchType.LAZY, cascade = CascadeType.MERGE)
private Modules modules;

@Type(type = "yes_no")
private boolean isPrimaryModule;

public boolean getIsPrimaryModule() {
    return isPrimaryModule;
}

}

The error is indeed fixed by inserting this with a type annotation as the first callback parameter. My attempt to do that was botched by simultaneously changing the callback into an arrow-function:

foo.on('error', (this: Foo, err: any) => { // DON'T DO THIS

It should've been this:

foo.on('error', function(this: Foo, err: any) {

or this:

foo.on('error', function(this: typeof foo, err: any) {

A GitHub issue was created to improve the compiler's error message and highlight the actual grammar error with this and arrow-functions.

You can use the Codecs module in the Python Standard Library, i.e.

import codecs

codecs.decode(hexstring, 'hex_codec')

The important thing about a sprint is that: within a sprint the functionality that is to be delivered is fixed.

A sprint is normally an iteration. But you can for example have a 4 week sprint, but have 4 one week "internal" iterations within that sprint.

There is a lot of discussion about the length of sprints. I think that if you do it according to the book they should all be the same length.

We have found that a short first sprint to get the development environment up and running, followed by longer basic functionality sprints, then short sprints towards the end of the project, has worked for us.

There are lots of things I have seen make a model diverge.

1. Too high of a learning rate. You can often tell if this is the case if the loss begins to increase and then diverges to infinity.

2. I am not to familiar with the DNNClassifier but I am guessing it uses the categorical cross entropy cost function. This involves taking the log of the prediction which diverges as the prediction approaches zero. That is why people usually add a small epsilon value to the prediction to prevent this divergence. I am guessing the DNNClassifier probably does this or uses the tensorflow opp for it. Probably not the issue.

3. Other numerical stability issues can exist such as division by zero where adding the epsilon can help. Another less obvious one if the square root who's derivative can diverge if not properly simplified when dealing with finite precision numbers. Yet again I doubt this is the issue in the case of the DNNClassifier.

4. You may have an issue with the input data. Try calling assert not np.any(np.isnan(x)) on the input data to make sure you are not introducing the nan. Also make sure all of the target values are valid. Finally, make sure the data is properly normalized. You probably want to have the pixels in the range [-1, 1] and not [0, 255].

5. The labels must be in the domain of the loss function, so if using a logarithmic-based loss function all labels must be non-negative (as noted by evan pu and the comments below).

This can be done by using the java.net.URI class to construct a new instance using the parts from an existing one, this should ensure it conforms to URI syntax.

The query part will either be null or an existing string, so you can decide to append another parameter with & or start a new query.

public class StackOverflow26177749 {

    public static URI appendUri(String uri, String appendQuery) throws URISyntaxException {
        URI oldUri = new URI(uri);

        String newQuery = oldUri.getQuery();
        if (newQuery == null) {
            newQuery = appendQuery;
        } else {
            newQuery += "&" + appendQuery;  
        }

        return new URI(oldUri.getScheme(), oldUri.getAuthority(),
                oldUri.getPath(), newQuery, oldUri.getFragment());
    }

    public static void main(String[] args) throws Exception {
        System.out.println(appendUri("http://example.com", "name=John"));
        System.out.println(appendUri("http://example.com#fragment", "name=John"));
        System.out.println(appendUri("http://[email protected]", "name=John"));
        System.out.println(appendUri("http://[email protected]#fragment", "name=John"));
    }
}

Shorter alternative

public static URI appendUri(String uri, String appendQuery) throws URISyntaxException {
    URI oldUri = new URI(uri);
    return new URI(oldUri.getScheme(), oldUri.getAuthority(), oldUri.getPath(),
            oldUri.getQuery() == null ? appendQuery : oldUri.getQuery() + "&" + appendQuery, oldUri.getFragment());
}

Output

http://example.com?name=John
http://example.com?name=John#fragment
http://[email protected]&name=John
http://[email protected]&name=John#fragment

In a word - speed. An index for up to a million rows fits in a 32-bit word, so it can be used efficiently on 32-bit processors. Function arguments that fit in a CPU register are extremely efficient, while ones that are larger require accessing memory on each function call, a far slower operation. Updating a spreadsheet can be an intensive operation involving many cell references, so speed is important. Besides, the Excel team expects that anyone dealing with more than a million rows will be using a database rather than a spreadsheet.

Looks like you forgot adding correct headers to your get request (ask the REST API developer or you specific API description):

HttpURLConnection connection = (HttpURLConnection)url.openConnection();
connection.header("Accept", "application/xml")
connection.setRequestMethod("GET");
connection.connect();

or

connection.header("Accept", "application/xml;version=1")

Conceptually there are the two "domains" classes and interfaces. Inside these domains you are always extending, only a class implements an interface, which is kind of "crossing the border". So basically "extends" for interfaces mirrors the behavior for classes. At least I think this is the logic behind. It seems than not everybody agrees with this kind of logic (I find it a little bit contrived myself), and in fact there is no technical reason to have two different keywords at all.

I have 2 php files and i made this, and it works. (this is an example) the first code is from the one file and the second code from two file.

<form action="two.php" method="post">
<input type="submit" class="button" value="submit" name="one"/>
<select name="numbers">
<option value="1"> 1 </option>
<option value="2"> 2 </option>
<option value="3"> 3 </option>
</select>
</form>



if(isset ($_POST['one']))
{

if($_POST['numbers']=='1')
{
$a='1' ;
}
else if($_POST['numbers']=='2')
{
$a='2' ;
{
else if ($_POST['numbers']=='3')
{
$a='3' ;
}

}

Since in my case I was performing a first commit of a project, simply deleting .git and .idea folders and then reinitializing git using git init helped to solve a problem. Now I don't have .idea at all.

I realize this is a very old post, but after looking at L.B's response I thought about how I could improve upon the accepted answer and make it generic for my own application. Here's what I came up with:

public static string Serialize<T>(T dataToSerialize)
{
    try
    {
        var stringwriter = new System.IO.StringWriter();
        var serializer = new XmlSerializer(typeof(T));
        serializer.Serialize(stringwriter, dataToSerialize);
        return stringwriter.ToString();
    }
    catch
    {
        throw;
    }
}

public static T Deserialize<T>(string xmlText)
{
    try
    {
        var stringReader = new System.IO.StringReader(xmlText);
        var serializer = new XmlSerializer(typeof(T));
        return (T)serializer.Deserialize(stringReader);
    }
    catch
    {
        throw;
    }
}

These methods can now be placed in a static helper class, which means no code duplication to every class that needs to be serialized.

Although both of them will fetch the same results, there is a significant difference in the performance of both the functions. reduceByKey() works better with larger datasets when compared to groupByKey().

In reduceByKey(), pairs on the same machine with the same key are combined (by using the function passed into reduceByKey()) before the data is shuffled. Then the function is called again to reduce all the values from each partition to produce one final result.

In groupByKey(), all the key-value pairs are shuffled around. This is a lot of unnecessary data to being transferred over the network.

Prototype version using ES6 as well. Basically this uses the reduce function to pass in an accumulator and current item, which then uses this to build your "grouped" arrays based on the passed in key. the inner part of the reduce may look complicated but essentially it is testing to see if the key of the passed in object exists and if it doesn't then create an empty array and append the current item to that newly created array otherwise using the spread operator pass in all the objects of the current key array and append current item. Hope this helps someone!.

Array.prototype.groupBy = function(k) {
  return this.reduce((acc, item) => ((acc[item[k]] = [...(acc[item[k]] || []), item]), acc),{});
};

const projs = [
  {
    project: "A",
    timeTake: 2,
    desc: "this is a description"
  },
  {
    project: "B",
    timeTake: 4,
    desc: "this is a description"
  },
  {
    project: "A",
    timeTake: 12,
    desc: "this is a description"
  },
  {
    project: "B",
    timeTake: 45,
    desc: "this is a description"
  }
];

console.log(projs.groupBy("project"));

You can see this solution. It shows how to get/set cookies, but cookies are just one of the headers in a request/response. You have to override one of the Volley's *Request classes and set the required headers in getHeaders()

Here is the linked source:

public class StringRequest extends com.android.volley.toolbox.StringRequest {

private final Map<String, String> _params;

/**
 * @param method
 * @param url
 * @param params
 *            A {@link HashMap} to post with the request. Null is allowed
 *            and indicates no parameters will be posted along with request.
 * @param listener
 * @param errorListener
 */
public StringRequest(int method, String url, Map<String, String> params, Listener<String> listener,
        ErrorListener errorListener) {
    super(method, url, listener, errorListener);

    _params = params;
}

@Override
protected Map<String, String> getParams() {
    return _params;
}

/* (non-Javadoc)
 * @see com.android.volley.toolbox.StringRequest#parseNetworkResponse(com.android.volley.NetworkResponse)
 */
@Override
protected Response<String> parseNetworkResponse(NetworkResponse response) {
    // since we don't know which of the two underlying network vehicles
    // will Volley use, we have to handle and store session cookies manually
    MyApp.get().checkSessionCookie(response.headers);

    return super.parseNetworkResponse(response);
}

/* (non-Javadoc)
 * @see com.android.volley.Request#getHeaders()
 */
@Override
public Map<String, String> getHeaders() throws AuthFailureError {
    Map<String, String> headers = super.getHeaders();

    if (headers == null
            || headers.equals(Collections.emptyMap())) {
        headers = new HashMap<String, String>();
    }

    MyApp.get().addSessionCookie(headers);

    return headers;
}

}

And MyApp class:

public class MyApp extends Application {
    private static final String SET_COOKIE_KEY = "Set-Cookie";
    private static final String COOKIE_KEY = "Cookie";
    private static final String SESSION_COOKIE = "sessionid";

    private static MyApp _instance;
    private RequestQueue _requestQueue;
    private SharedPreferences _preferences;

    public static MyApp get() {
        return _instance;
    }

    @Override
    public void onCreate() {
        super.onCreate();
        _instance = this;
            _preferences = PreferenceManager.getDefaultSharedPreferences(this);
        _requestQueue = Volley.newRequestQueue(this);
    }

    public RequestQueue getRequestQueue() {
        return _requestQueue;
    }


    /**
     * Checks the response headers for session cookie and saves it
     * if it finds it.
     * @param headers Response Headers.
     */
    public final void checkSessionCookie(Map<String, String> headers) {
        if (headers.containsKey(SET_COOKIE_KEY)
                && headers.get(SET_COOKIE_KEY).startsWith(SESSION_COOKIE)) {
                String cookie = headers.get(SET_COOKIE_KEY);
                if (cookie.length() > 0) {
                    String[] splitCookie = cookie.split(";");
                    String[] splitSessionId = splitCookie[0].split("=");
                    cookie = splitSessionId[1];
                    Editor prefEditor = _preferences.edit();
                    prefEditor.putString(SESSION_COOKIE, cookie);
                    prefEditor.commit();
                }
            }
    }

    /**
     * Adds session cookie to headers if exists.
     * @param headers
     */
    public final void addSessionCookie(Map<String, String> headers) {
        String sessionId = _preferences.getString(SESSION_COOKIE, "");
        if (sessionId.length() > 0) {
            StringBuilder builder = new StringBuilder();
            builder.append(SESSION_COOKIE);
            builder.append("=");
            builder.append(sessionId);
            if (headers.containsKey(COOKIE_KEY)) {
                builder.append("; ");
                builder.append(headers.get(COOKIE_KEY));
            }
            headers.put(COOKIE_KEY, builder.toString());
        }
    }

}

It may not be an easy problem. Determining how to map classes defined in Python into types in Java will be a big challange because of differences in each of type binding time. (duck typing vs. compile time binding).

I found that the problem is that I only have a production environment. I do not have a development or test environment.

By adding 'RAILS_ENV=production' to give the command

bundle exec rake redmine:plugins:migrate RAILS_ENV=production

it worked

One pitfall I fell into is there is no password field now, it has been renamed so:

update user set password=PASSWORD("YOURPASSWORDHERE") where user='root';

Should now be:

update user set authentication_string=password('YOURPASSWORDHERE') where user='root';

After zach I would also recommend boto, but I needed to make a slight difference to his code:

conn = boto.connect_s3('access-key', 'secret'key')
bucket = conn.lookup('bucket-name')
for key in bucket:
    print key.name

You must need to specify columns name which you want to insert if there is an Identity column. So the command will be like this below:

SET IDENTITY_INSERT DuplicateTable ON

INSERT Into DuplicateTable ([IdentityColumn], [Column2], [Column3], [Column4] ) 
SELECT [IdentityColumn], [Column2], [Column3], [Column4] FROM MainTable

SET IDENTITY_INSERT DuplicateTable OFF

If your table has many columns then get those columns name by using this command.

SELECT column_name + ','
FROM   information_schema.columns 
WHERE  table_name = 'TableName'
for xml path('')

(after removing the last comma(',')) Just copy past columns name.

It leaves blank pages so that a new part or chapter start on the right-hand side. You can fix this with the "openany" option for the document class. ;)

First, you can use sql command show global variables like 'innodb_buffer%'; to check the buffer size.

Solution is find your my.cnf file and add,

[mysqld]_x000D_
innodb_buffer_pool_size=1G # depends on your data and machine

DO NOT forget to add [mysqld], otherwise, it won't work.

In my case, ubuntu 16.04, my.cnf is located under the folder /etc/mysql/.

To Change Button title:

[mybtn setTitle:@"My Button" forState:UIControlStateNormal];

docker logs -f <yourContainer> &> your.log &

Explanation:

• -f (i.e.--follow): writes all existing logs and continues (follows) logging everything that comes next.
• &> redirects both the standard output and standard error.
• Likely you want to run that method in the background, thus the &.
• You can separate output and stderr by: > output.log 2> error.log (instead of using &>).

That's one of the reasons why you need to quote your variables:

echo "${str:$i:1}"

Otherwise, bash expands the variable and in this case does globbing before printing out. It is also better to quote the parameter to the script (in case you have a matching filename):

sh lash_ch.sh 'abcde*'

Also see the order of expansions in the bash reference manual. Variables are expanded before the filename expansion.

To get the last character you should just use -1 as the index since the negative indices count from the end of the string:

echo "${str: -1}"

The space after the colon (:) is REQUIRED.

This approach will not work without the space.

I think Candy's answer is mostly correct. There is one small part I think otherwise.

To map host:port/context/hello.jsp

1. No exact URL servlets installed, next.
2. Found wildcard paths servlets, return.

I believe that why "/*" does not match host:port/context/hello because it treats "/hello" as a path instead of a file (since it does not have an extension).

Yes, when you import classes with the same simple names, you must refer to them by their fully qualified class names. I would leave the import statements in, as it gives other developers a sense of what is in the file when they are working with it.

java.util.Data date1 = new java.util.Date();
my.own.Date date2 = new my.own.Date();

In python notebooks I often want to filter out 'dangling' numpy.ndarray's, in particular the ones that are stored in _1, _2, etc that were never really meant to stay alive.

I use this code to get a listing of all of them and their size.

Not sure if locals() or globals() is better here.

import sys
import numpy
from humanize import naturalsize

for size, name in sorted(
    (value.nbytes, name)
    for name, value in locals().items()
    if isinstance(value, numpy.ndarray)):
  print("{:>30}: {:>8}".format(name, naturalsize(size)))

ThomasH has already added a good answer, but I want to show what happens:

>>> a = [[1, 2], [3, 4]]
>>> [x for x in b for b in a]
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'b' is not defined

>>> [x for b in a for x in b]
[1, 2, 3, 4]
>>> [x for x in b for b in a]
[3, 3, 4, 4]

I guess Python parses the list comprehension from left to right. This means, the first for loop that occurs will be executed first.

The second "problem" of this is that b gets "leaked" out of the list comprehension. After the first successful list comprehension b == [3, 4].

On the server, try:

netstat -an 

and look to see if tcp port 22 is opened (use findstr in Windows or grep in Unix).

re.findall finds all the occurrence of the regex in a string and return in a list. Here, you are using a list of strings, you need this to use re.findall

Note - If the regex fails, an empty list is returned.

import re, sys

f = open('picklee', 'r')
lines = f.readlines()  
regex = re.compile(r'[A-Z]+')
for line in lines:
     print (re.findall(regex, line))

I tried SHIFT + SHIFT and ALT + CMD + O

But I think the most powerful and easy to use feature is find in all files CMD + SHIFT + F.

Choose regex and write .*partOfMethodName.*\( and it shows all places and can see the actual source code in place without going to that specific file.

If your object contains a set of data you want to bind your object's iter to, you can cheat and do this:

>>> class foo:
    def __init__(self, *params):
           self.data = params
    def __iter__(self):
        if hasattr(self.data[0], "__iter__"):
            return self.data[0].__iter__()
        return self.data.__iter__()
>>> d=foo(6,7,3,8, "ads", 6)
>>> for i in d:
    print i
6
7
3
8

The answer given by Nico O is correct. However this doesn't get the desired result on Internet Explorer 10 to 11 and Firefox.

For IE, I found that changing

.flex > div
{
   flex: 1 0 50%;
}

to

.flex > div
{
   flex: 1 0 45%;
}

seems to do the trick. Don't ask me why, I haven't gone any further into this but it might have something to do with how IE renders the border-box or something.

In the case of Firefox I solved it by adding

display: inline-block;

to the items.

userType = (user.Type == 0) ? "Admin" : (user.type == 1) ? "User" : "Admin";

should do the trick.

Check your tableview frame in storyboard or xib. Mine by default has a y position value, hence the bug

Check out my highly simplified Echo example: It is designed to use basic HTTP communication, but it can easily be modified to use named pipes by editing the app.config files for the client and server. Make the following changes:

Edit the server's app.config file, removing or commenting out the http baseAddress entry and adding a new baseAddress entry for the named pipe (called net.pipe). Also, if you don't intend on using HTTP for a communication protocol, make sure the serviceMetadata and serviceDebug is either commented out or deleted:

<configuration>
    <system.serviceModel>
        <services>
            <service name="com.aschneider.examples.wcf.services.EchoService">
                <host>
                    <baseAddresses>
                        <add baseAddress="net.pipe://localhost/EchoService"/>
                    </baseAddresses>
                </host>
            </service>
        </services>
        <behaviors>
            <serviceBehaviors></serviceBehaviors>
        </behaviors>
    </system.serviceModel>
</configuration>

Edit the client's app.config file so that the basicHttpBinding is either commented out or deleted and a netNamedPipeBinding entry is added. You will also need to change the endpoint entry to use the pipe:

<configuration>
    <system.serviceModel>
        <bindings>
            <netNamedPipeBinding>
                <binding name="NetNamedPipeBinding_IEchoService"/>
            </netNamedPipeBinding>
        </bindings>
        <client>
            <endpoint address              = "net.pipe://localhost/EchoService"
                      binding              = "netNamedPipeBinding"
                      bindingConfiguration = "NetNamedPipeBinding_IEchoService"
                      contract             = "EchoServiceReference.IEchoService"
                      name                 = "NetNamedPipeBinding_IEchoService"/>
        </client>
    </system.serviceModel>
</configuration>

The above example will only run with named pipes, but nothing is stopping you from using multiple protocols to run your service. AFAIK, you should be able to have a server run a service using both named pipes and HTTP (as well as other protocols).

Also, the binding in the client's app.config file is highly simplified. There are many different parameters you can adjust, aside from just specifying the baseAddress...

Difference in DLL and EXE:

1) DLL is an In-Process Component which means running in the same memory space as the client process. EXE is an Out-Process Component which means it runs in its own separate memory space.

2) The DLL contains functions and procedures that other programs can use (promotes reuability) while EXE cannot be shared with other programs.

3) DLL cannot be directly executed as they're designed to be loaded and run by other programs. EXE is a program that is executed directly.

Please search the site before asking questions next time: how to concatenate two dictionaries to create a new one in Python?

The easiest way to do it is to simply use your example code, but using the items() member of each dictionary. So, the code would be:

dic0 = {'dic0': 0}
dic1 = {'dic1': 1}
dic2 = dict(dic0.items() + dic1.items())

I tested this in IDLE and it works fine. However, the previous question on this topic states that this method is slow and chews up memory. There are several other ways recommended there, so please see that if memory usage is important.

For anyone who is searching for a solution about posting to Instagram using AWS lambda and puppeteer (chrome-aws-lambda). Noted that this solution allow you to post 1 photo for each post only. If you are not using lambda, just replace chrome-aws-lambda with puppeteer.

For the first launch of lambda, it is normal that will not work because instagram detects “Suspicious login attempt”. Just goto instagram page using your PC and approve it, everything should be fine.

Here's my code, feel free to optimize it:

// instagram.js
const chromium = require('chrome-aws-lambda');

const username = process.env.IG_USERNAME;
const password = process.env.IG_PASSWORD;

module.exports.post = async function(fileToUpload, caption){
    const browser = await chromium.puppeteer.launch({
        args: [...chromium.args, '--window-size=520,700'],
        defaultViewport: chromium.defaultViewport,

just remove s from the permission you are using sss you have to use ss

This one worked, double quotes when $user and $password are outside single quotes. Single quotes when inside a single quote statement.

mysql --user="$user" --password="$password" --database="$user" --execute='DROP DATABASE '$user'; CREATE DATABASE '$user';'

Just type:

I'm using python2.7 on a mac with iTerm2.

I was using a Node http request and listening for the data event. This event only puts the data into a buffer temporarily, and so a complete JSON is not available. To fix, each data event must be appended to a variable. Might help someone (http://nodejs.org/api/http.html).

You might be interested in the calc approach:

font-size: calc(4vw + 4vh + 2vmin);

done. Tweak values till matches your taste.

Actually if you create func:

create function p1() returns INTEGER DETERMINISTIC NO SQL return @p1;

and view:

create view h_parm as
select * from sw_hardware_big where unit_id = p1() ;

Then you can call a view with a parameter:

select s.* from (select @p1:=12 p) parm , h_parm s;

I hope it helps.

Try this. I purposely broke out various parts so you can move things around.

y <- 1:100000

#Setup the plot area
par(pty="m", plt=c(0.1, 1, 0.1, 1), omd=c(0.1,0.9,0.1,0.9))

#Plot a blank graph without completing the x or y axis

mtext(side=1, text="x", line=2.5)

#Complete the y axis and add the grid
aty <- seq(par("yaxp")[1], par("yaxp")[2], (par("yaxp")[2] - par("yaxp")[1])/par("yaxp")[3])
axis(2, at=aty, labels=format(aty, scientific=FALSE), hadj=0.9, cex.axis=0.8, las=2)
mtext(side=2, text="y", line=4.5)

If your file looks like this:

[
    {
        "firstname": "toto",
        "lastname": "titi"
    },
    {
        "firstname": "toto2",
        "lastname": "titi2"
    },
]

You can do:

import json from './json/data.json';
// ....
json.forEach(x => { console.log(x.firstname, x.lastname); });

On Macs, (assuming you have the right version installed)

JAVA_HOME=`/usr/libexec/java_home -v 1.8` mvn clean install -DskipTests

Create a list of column names you want to add up.

df['total']=df.loc[:,list_name].sum(axis=1)

If you want the sum for certain rows, specify the rows using ':'

setTimeout(func, 5000);

-- it will call the function named func() after the time specified. here, 5000 milli seconds , i.e) after 5 seconds

When using the superglobals like $_GET or $_REQUEST you should be aware that they could be an empty string. In this specal case this example

$username = $_GET['user'] ?? 'nobody';

will fail because the value of $username now is an empty string.

So when using $_GET or even $_REQUEST you should use the ternary operator instead like this:

$username = (!empty($_GET['user'])?$_GET['user']:'nobody';

Now the value of $username is 'nobody' as expected.

Running a Python Script in the Background

First, you need to add a shebang line in the Python script which looks like the following:

#!/usr/bin/env python3

This path is necessary if you have multiple versions of Python installed and /usr/bin/env will ensure that the first Python interpreter in your $$PATH environment variable is taken. You can also hardcode the path of your Python interpreter (e.g. #!/usr/bin/python3), but this is not flexible and not portable on other machines. Next, you’ll need to set the permissions of the file to allow execution:

chmod +x test.py

Now you can run the script with nohup which ignores the hangup signal. This means that you can close the terminal without stopping the execution. Also, don’t forget to add & so the script runs in the background:

nohup /path/to/test.py &

If you did not add a shebang to the file you can instead run the script with this command:

nohup python /path/to/test.py &

The output will be saved in the nohup.out file, unless you specify the output file like here:

nohup /path/to/test.py > output.log &
nohup python /path/to/test.py > output.log &

If you have redirected the output of the command somewhere else - including /dev/null - that's where it goes instead.

# doesn't create nohup.out

nohup command >/dev/null 2>&1   

If you're using nohup, that probably means you want to run the command in the background by putting another & on the end of the whole thing:

# runs in background, still doesn't create nohup.out

 nohup command >/dev/null 2>&1 &  

You can find the process and its process ID with this command:

ps ax | grep test.py

# or
# list of running processes Python

ps -fA | grep python

ps stands for process status

If you want to stop the execution, you can kill it with the kill command:

kill PID

I'm not familiar with c++, but a quick look at the documentation suggests that this should work:

//cin>>CC; cin>>RR; already done
vector<vector<int> > matrix;
for(int i = 0; i<RR; i++)
{
    vector<int> myvector;
    for(int j = 0; j<CC; j++)
    {
        int tempVal = 0;
        cout<<"Enter the number for Matrix 1";
        cin>>tempVal;
        myvector.push_back(tempVal);
    }
    matrix.push_back(myvector);
}

(//*[@attribute='value'])[index] to find target of element while your finding multiple matches in it

I have re-wrote by hand, these encoding and decoding methods with the exception of the hexadecimal one into a modular format for cross-platform / browser compatibility and also with real private scoping, and uses btoa and atob if they exist due to speed rather than utilize its own encoding:

https://gist.github.com/Nijikokun/5192472

Usage:

base64.encode(/* String */);
base64.decode(/* String */);

utf8.encode(/* String */);
utf8.decode(/* String */);

I use POST body for anything non-trivial and line-of-business apps for these reasons:

1. Security - If we use GET with query strings and https, the query strings can be saved in server logs and forwarded as referral links. Both of these are now visible by server/network admins and the next domain the user went to after leaving your app. So if we send a query containing confidential PII data such as a customer's name this may not be desired.
2. URL maximum length - Not a big issue, but some browsers have a limit on the length. So if we have several items in our URL like query, paging, fields to return, etc....
3. POST is not cached by default. Some say caching is desired; however, how often is that exact same set of search criteria for that exact object for that exact customer going to occur before the cache times out anyway?

BTW, I also put the fields to return in my POST body as I may not wish to expose my field names. Security is like an onion; it has many layers and makes us cry!

For future readers who found this question while trying to save high resolution images from matplotlib as I am, I have tried some of the answers above and elsewhere, and summed them up here.

Best result: plt.savefig('filename.pdf')

and then converting this pdf to a png on the command line so you can use it in powerpoint:

pdftoppm -png -r 300 filename.pdf filename

OR simply opening the pdf and cropping to the image you need in adobe, saving as a png and importing the picture to powerpoint

Less successful test #1: plt.savefig('filename.png', dpi=300)

This does save the image at a bit higher than the normal resolution, but it isn't high enough for publication or some presentations. Using a dpi value of up to 2000 still produced blurry images when viewed close up.

Less successful test #2: plt.savefig('filename.pdf')

This cannot be opened in Microsoft Office Professional Plus 2016 (so no powerpoint), same with Google Slides.

Less successful test #3: plt.savefig('filename.svg')

This also cannot be opened in powerpoint or Google Slides, with the same issue as above.

Less successful test #4: plt.savefig('filename.pdf')

and then converting to png on the command line:

convert -density 300 filename.pdf filename.png

but this is still too blurry when viewed close up.

Less successful test #5: plt.savefig('filename.pdf')

and opening in GIMP, and exporting as a high quality png (increased the file size from ~100 KB to ~75 MB)

Less successful test #6: plt.savefig('filename.pdf')

and then converting to jpeg on the command line:

pdfimages -j filename.pdf filename

This did not produce any errors but did not produce an output on Ubuntu even after changing around several parameters.

Using ApplicationContextAware is tying you to Spring (which may or may not be an issue). I would recommend passing in a LoginActionFactory, which you can ask for a new instance of a LoginAction each time you need one.

Using the HttpClientBuilder in HttpClient 4.5.x with a custom HttpClientConnectionManager with the defaults of HttpClientBuilder :

SSLConnectionSocketFactory sslConnectionSocketFactory = 
    new SSLConnectionSocketFactory(SSLContexts.createDefault(),          
                                   new String[] { "TLSv1.2" },                                            
                                   null, 
           SSLConnectionSocketFactory.getDefaultHostnameVerifier());

PoolingHttpClientConnectionManager poolingHttpClientConnectionManager =
    new PoolingHttpClientConnectionManager(
        RegistryBuilder.<ConnectionSocketFactory> create()
                       .register("http",
                                 PlainConnectionSocketFactory.getSocketFactory())
                       .register("https",
                                 sslConnectionSocketFactory)
                       .build());

// Customize the connection pool

CloseableHttpClient httpClient = HttpClientBuilder.create()
                                                  .setConnectionManager(poolingHttpClientConnectionManager)
                                                  .build()

Without a custom HttpClientConnectionManager :

SSLConnectionSocketFactory sslConnectionSocketFactory = 
    new SSLConnectionSocketFactory(SSLContexts.createDefault(),          
                                   new String[] { "TLSv1.2" },                                            
                                   null, 
           SSLConnectionSocketFactory.getDefaultHostnameVerifier());

CloseableHttpClient httpClient = HttpClientBuilder.create()
                                                  .setSSLSocketFactory(sslConnectionSocketFactory)
                                                  .build()

Simplest solution and workaround:

<input name="toRent" type="radio" (click)="setToRentControl(false)">
<input name="toRent" type="radio" (click)="setToRentControl(true)">

setToRentControl(value){
    this.vm.toRent.updateValue(value);
    alert(value); //true/false
}

Creating a new Function by Binding Arguments to Values

The bind method creates a new function from another function with one or more arguments bound to specific values, including the implicit this argument.

Partial Application

This is an example of partial application. Normally we supply a function with all of its arguments which yields a value. This is known as function application. We are applying the function to its arguments.

A Higher Order Function (HOF)

Partial application is an example of a higher order function (HOF) because it yields a new function with a fewer number of argument.

Binding Multiple Arguments

You can use bind to transform functions with multiple arguments into new functions.

function multiply(x, y) { _x000D_
    return x * y; _x000D_
}_x000D_
_x000D_
let multiplyBy10 = multiply.bind(null, 10);_x000D_
console.log(multiplyBy10(5));

Converting from Instance Method to Static Function

In the most common use case, when called with one argument the bind method will create a new function that has the this value bound to a specific value. In effect this transforms an instance method to a static method.

function Multiplier(factor) { _x000D_
    this.factor = factor;_x000D_
}_x000D_
_x000D_
Multiplier.prototype.multiply = function(x) { _x000D_
    return this.factor * x; _x000D_
}_x000D_
_x000D_
function ApplyFunction(func, value) {_x000D_
    return func(value);_x000D_
}_x000D_
_x000D_
var mul = new Multiplier(5);_x000D_
_x000D_
// Produces garbage (NaN) because multiplying "undefined" by 10_x000D_
console.log(ApplyFunction(mul.multiply, 10));_x000D_
_x000D_
// Produces expected result: 50_x000D_
console.log(ApplyFunction(mul.multiply.bind(mul), 10));

Implementing a Stateful CallBack

The following example shows how using binding of this can enable an object method to act as a callback that can easily update the state of an object.

function ButtonPressedLogger()_x000D_
{_x000D_
   this.count = 0;_x000D_
   this.onPressed = function() {_x000D_
      this.count++;_x000D_
      console.log("pressed a button " + this.count + " times");_x000D_
   }_x000D_
   for (let d of document.getElementsByTagName("button"))_x000D_
      d.onclick = this.onPressed.bind(this);_x000D_
}_x000D_
_x000D_
new ButtonPressedLogger();      

<button>press me</button>_x000D_
<button>no press me</button>

For those like me who are brand new to this, here is code with const and an actual way to compare the byte[]'s. I got all of this code from stackoverflow but defined consts so values could be changed and also

// 24 = 192 bits
    private const int SaltByteSize = 24;
    private const int HashByteSize = 24;
    private const int HasingIterationsCount = 10101;


    public static string HashPassword(string password)
    {
        // http://stackoverflow.com/questions/19957176/asp-net-identity-password-hashing

        byte[] salt;
        byte[] buffer2;
        if (password == null)
        {
            throw new ArgumentNullException("password");
        }
        using (Rfc2898DeriveBytes bytes = new Rfc2898DeriveBytes(password, SaltByteSize, HasingIterationsCount))
        {
            salt = bytes.Salt;
            buffer2 = bytes.GetBytes(HashByteSize);
        }
        byte[] dst = new byte[(SaltByteSize + HashByteSize) + 1];
        Buffer.BlockCopy(salt, 0, dst, 1, SaltByteSize);
        Buffer.BlockCopy(buffer2, 0, dst, SaltByteSize + 1, HashByteSize);
        return Convert.ToBase64String(dst);
    }

    public static bool VerifyHashedPassword(string hashedPassword, string password)
    {
        byte[] _passwordHashBytes;

        int _arrayLen = (SaltByteSize + HashByteSize) + 1;

        if (hashedPassword == null)
        {
            return false;
        }

        if (password == null)
        {
            throw new ArgumentNullException("password");
        }

        byte[] src = Convert.FromBase64String(hashedPassword);

        if ((src.Length != _arrayLen) || (src[0] != 0))
        {
            return false;
        }

        byte[] _currentSaltBytes = new byte[SaltByteSize];
        Buffer.BlockCopy(src, 1, _currentSaltBytes, 0, SaltByteSize);

        byte[] _currentHashBytes = new byte[HashByteSize];
        Buffer.BlockCopy(src, SaltByteSize + 1, _currentHashBytes, 0, HashByteSize);

        using (Rfc2898DeriveBytes bytes = new Rfc2898DeriveBytes(password, _currentSaltBytes, HasingIterationsCount))
        {
            _passwordHashBytes = bytes.GetBytes(SaltByteSize);
        }

        return AreHashesEqual(_currentHashBytes, _passwordHashBytes);

    }

    private static bool AreHashesEqual(byte[] firstHash, byte[] secondHash)
    {
        int _minHashLength = firstHash.Length <= secondHash.Length ? firstHash.Length : secondHash.Length;
        var xor = firstHash.Length ^ secondHash.Length;
        for (int i = 0; i < _minHashLength; i++)
            xor |= firstHash[i] ^ secondHash[i];
        return 0 == xor;
    }

In in your custom ApplicationUserManager, you set the PasswordHasher property the name of the class which contains the above code.

If you are aiming for maximum browser support, modern approach is to place button in a div with display:flex; and flex-direction:row; The same trick will work for height with flex-direction:column; or both height and width(will require 2 divs)

The general practice is to have the central repository to which you push as a bare repo.

If you have SVN background, you can relate an SVN repo to a Git bare repo. It doesn't have the files in the repo in the original form. Whereas your local repo will have the files that form your "code" in addition.

You need to add a remote to the bare repo from your local repo and push your "code" to it.

It will be something like:

git remote add central <url> # url will be ssh based for you
git push --all central

In order to get the column information you can use the following snippet:

String sql = "select * from "+oTablename+" LIMIT 0";
Statement statement = connection.createStatement();
ResultSet rs = statement.executeQuery(sql);
ResultSetMetaData mrs = rs.getMetaData();
for(int i = 1; i <= mrs.getColumnCount(); i++)
{
    Object row[] = new Object[3];
    row[0] = mrs.getColumnLabel(i);
    row[1] = mrs.getColumnTypeName(i);
    row[2] = mrs.getPrecision(i);
}

Here I'm basically wrapping a button in a link. The advantage is that you can post to different action methods in the same form.

<a href="Controller/ActionMethod">
    <input type="button" value="Click Me" />
</a>

Adding parameters:

<a href="Controller/ActionMethod?userName=ted">
    <input type="button" value="Click Me" />
</a>

Adding parameters from a non-enumerated Model:

<a href="Controller/[email protected]">
    <input type="button" value="Click Me" />
</a>

You can do the same for an enumerated Model too. You would just have to reference a single entity first. Happy Coding!

Step 1: check your default authentication plugin

SHOW VARIABLES LIKE 'default_authentication_plugin';

Step 2: veryfing your password validation requirements

SHOW VARIABLES LIKE 'validate_password%';

Step 3: setting up your user with correct password requirements

CREATE USER '<your_user>'@'localhost' IDENTIFIED WITH '<your_default_auth_plugin>' BY 'password';

Isn't this a much simpler solution, if I correctly understand the question, of course.

I want to load email addresses that are in a table called "spam" into a variable.

select email from spam

produces the following list, say:

.accountant
.bid
.buiilldanything.com
.club
.cn
.cricket
.date
.download
.eu

To load into the variable @list:

declare @list as varchar(8000)
set @list += @list (select email from spam)

@list may now be INSERTed into a table, etc.

I hope this helps.

To use it for a .csv file or in VB, spike the code:

declare @list as varchar(8000)
set @list += @list (select '"'+email+',"' from spam)
print @list

and it produces ready-made code to use elsewhere:

".accountant,"
".bid,"
".buiilldanything.com,"
".club,"
".cn,"
".cricket,"
".date,"
".download,"
".eu,"

One can be very creative.

Thanks

You can use java.util.Arrays.binarySearch to find an element in an array or to check for its existence:

import java.util.Arrays;
...

char[] array = new char[] {'a', 'x', 'm'};
Arrays.sort(array); 
if (Arrays.binarySearch(array, 'm') >= 0) {
    System.out.println("Yes, m is there");
}

Be aware that for binarySearch to work correctly, the array needs to be sorted. Hence the call to Arrays.sort() in the example. If your data is already sorted, you don't need to do that. Thus, this isn't strictly a one-liner if you need to sort your array first. Unfortunately, Arrays.sort() does not return a reference to the array - thus it is not possible to combine sort and binarySearch (i.e. Arrays.binarySearch(Arrays.sort(myArray), key)) does not work).

If you can afford the extra allocation, using Arrays.asList() seems cleaner.

Nowadays, in 90% of case if you working with URL in Python you probably use python-requests. Hence the question here - why not reuse URL validation from requests?

from requests.models import PreparedRequest
import requests.exceptions


def check_url(url):
    prepared_request = PreparedRequest()
    try:
        prepared_request.prepare_url(url, None)
        return prepared_request.url
    except requests.exceptions.MissingSchema, e:
        raise SomeException

• Don't reinvent the wheel
• DRY

There is another route of failure, besides the version of Java you are running: You could be running out of Heap/RAM

If you had a once working version of SQLDeveloper, and you are starting to see the screenshot referenced in the original post, then you can try to adjust the amount of space SQLDeveloper requests when starting up.

Edit the file:

/ide/bin/ide.conf

Edit the line that specifies the max ram to use: AddVMOption -Xmx, reducing the size. For example I changed my file to have the following lines, which solved the issue.

#AddVMOption  -Xmx640M   # Original Value
AddVMOption  -Xmx256M    # New Value

I think this is the syntax you are looking for:

if [ -z != $errorstatus ] 
then
commands
else
commands
fi

The biggest difference is their functionality. push_back always puts a new element at the end of the vector and insert allows you to select new element's position. This impacts the performance. vector elements are moved in the memory only when it's necessary to increase it's length because too little memory was allocated for it. On the other hand insert forces to move all elements after the selected position of a new element. You simply have to make a place for it. This is why insert might often be less efficient than push_back.

If the imagestr was bitmap data (which we now know it isn't) you could use this

imagestr is the base64 encoded string
width is the width of the image
height is the height of the image

from PIL import Image
from base64 import decodestring

image = Image.fromstring('RGB',(width,height),decodestring(imagestr))
image.save("foo.png")

Since the imagestr is just the encoded png data

from base64 import decodestring

with open("foo.png","wb") as f:
    f.write(decodestring(imagestr))

If you have more then one UITextFields and you need to do something when (or before) keyboard appears or disappears, you can implement this approach.

Add UITextFieldDelegate to your class. Assign integer counter, let's say:

NSInteger editCounter; 

Set this counter to zero somewhere in viewDidLoad. Then, implement textFieldShouldBeginEditing and textFieldShouldEndEditing delegate methods.

In the first one add 1 to editCounter. If value of editCounter becomes 1 - this means that keyboard will appear (in case if you return YES). If editCounter > 1 - this means that keyboard is already visible and another UITextField holds the focus.

In textFieldShouldEndEditing subtract 1 from editCounter. If you get zero - keyboard will be dismissed, otherwise it will remain on the screen.

You have to merge your files first. Do a git status to see what are the files that need to be merged (means you need to resolve the conflicts first). Once this is done, do git add file_merged and do your pull again.

You'd normally use java.net.URLConnection to fire HTTP requests. You'd also normally use multipart/form-data encoding for mixed POST content (binary and character data). Click the link, it contains information and an example how to compose a multipart/form-data request body. The specification is in more detail described in RFC2388.

Here's a kickoff example:

String url = "http://example.com/upload";
String charset = "UTF-8";
String param = "value";
File textFile = new File("/path/to/file.txt");
File binaryFile = new File("/path/to/file.bin");
String boundary = Long.toHexString(System.currentTimeMillis()); // Just generate some unique random value.
String CRLF = "\r\n"; // Line separator required by multipart/form-data.

URLConnection connection = new URL(url).openConnection();
connection.setDoOutput(true);
connection.setRequestProperty("Content-Type", "multipart/form-data; boundary=" + boundary);

try (
    OutputStream output = connection.getOutputStream();
    PrintWriter writer = new PrintWriter(new OutputStreamWriter(output, charset), true);
) {
    // Send normal param.
    writer.append("--" + boundary).append(CRLF);
    writer.append("Content-Disposition: form-data; name=\"param\"").append(CRLF);
    writer.append("Content-Type: text/plain; charset=" + charset).append(CRLF);
    writer.append(CRLF).append(param).append(CRLF).flush();

    // Send text file.
    writer.append("--" + boundary).append(CRLF);
    writer.append("Content-Disposition: form-data; name=\"textFile\"; filename=\"" + textFile.getName() + "\"").append(CRLF);
    writer.append("Content-Type: text/plain; charset=" + charset).append(CRLF); // Text file itself must be saved in this charset!
    writer.append(CRLF).flush();
    Files.copy(textFile.toPath(), output);
    output.flush(); // Important before continuing with writer!
    writer.append(CRLF).flush(); // CRLF is important! It indicates end of boundary.

    // Send binary file.
    writer.append("--" + boundary).append(CRLF);
    writer.append("Content-Disposition: form-data; name=\"binaryFile\"; filename=\"" + binaryFile.getName() + "\"").append(CRLF);
    writer.append("Content-Type: " + URLConnection.guessContentTypeFromName(binaryFile.getName())).append(CRLF);
    writer.append("Content-Transfer-Encoding: binary").append(CRLF);
    writer.append(CRLF).flush();
    Files.copy(binaryFile.toPath(), output);
    output.flush(); // Important before continuing with writer!
    writer.append(CRLF).flush(); // CRLF is important! It indicates end of boundary.

    // End of multipart/form-data.
    writer.append("--" + boundary + "--").append(CRLF).flush();
}

// Request is lazily fired whenever you need to obtain information about response.
int responseCode = ((HttpURLConnection) connection).getResponseCode();
System.out.println(responseCode); // Should be 200

This code is less verbose when you use a 3rd party library like Apache Commons HttpComponents Client.

The Apache Commons FileUpload as some incorrectly suggest here is only of interest in the server side. You can't use and don't need it at the client side.

I have spent a lot of time trying to figure this out, for devices with scaling factor is very difficult to get the actual size of the screen due to the scaling factor sometimes 125% or 150% when the calls are made to the C# objects the returning value is not the right now, so you need to make a windows API call to get the scaling factor and apply the multiplier, the only working way that I have found for non WPF apps is here

I don't know this off the top of my head, but look in the file which shows the user's name, etc in the header of the page after the user has logged in. It might help if you turned on template hints (see this tutorial.

    x = msvcrt.kbhit()
    if x:

        ret = msvcrt.getch()
    else:
        ret = False
    return ret

The real rule is: Don't throw away exceptions. The objectivity of the author of your quote is questionable, as evidenced by the fact that it ends with

or I will stab you

Of course, be aware that signals (by default) throw exceptions, and normally long-running processes are terminated through a signal, so catching Exception and not terminating on signal exceptions will make your program very hard to stop. So don't do this:

#! /usr/bin/ruby

while true do
  begin
    line = STDIN.gets
    # heavy processing
  rescue Exception => e
    puts "caught exception #{e}! ohnoes!"
  end
end

No, really, don't do it. Don't even run that to see if it works.

However, say you have a threaded server and you want all exceptions to not:

1. be ignored (the default)
2. stop the server (which happens if you say thread.abort_on_exception = true).

Then this is perfectly acceptable in your connection handling thread:

begin
  # do stuff
rescue Exception => e
  myLogger.error("uncaught #{e} exception while handling connection: #{e.message}")
    myLogger.error("Stack trace: #{backtrace.map {|l| "  #{l}\n"}.join}")
end

The above works out to a variation of Ruby's default exception handler, with the advantage that it doesn't also kill your program. Rails does this in its request handler.

Signal exceptions are raised in the main thread. Background threads won't get them, so there is no point in trying to catch them there.

This is particularly useful in a production environment, where you do not want your program to simply stop whenever something goes wrong. Then you can take the stack dumps in your logs and add to your code to deal with specific exception further down the call chain and in a more graceful manner.

Note also that there is another Ruby idiom which has much the same effect:

a = do_something rescue "something else"

In this line, if do_something raises an exception, it is caught by Ruby, thrown away, and a is assigned "something else".

Generally, don't do that, except in special cases where you know you don't need to worry. One example:

debugger rescue nil

The debugger function is a rather nice way to set a breakpoint in your code, but if running outside a debugger, and Rails, it raises an exception. Now theoretically you shouldn't be leaving debug code lying around in your program (pff! nobody does that!) but you might want to keep it there for a while for some reason, but not continually run your debugger.

Note:

1. If you've run someone else's program that catches signal exceptions and ignores them, (say the code above) then:

   • in Linux, in a shell, type pgrep ruby, or ps | grep ruby, look for your offending program's PID, and then run kill -9 <PID>.
   • in Windows, use the Task Manager (CTRL-SHIFT-ESC), go to the "processes" tab, find your process, right click it and select "End process".

2. If you are working with someone else's program which is, for whatever reason, peppered with these ignore-exception blocks, then putting this at the top of the mainline is one possible cop-out:

   %W/INT QUIT TERM/.each { |sig| trap sig,"SYSTEM_DEFAULT" }
   

   This causes the program to respond to the normal termination signals by immediately terminating, bypassing exception handlers, with no cleanup. So it could cause data loss or similar. Be careful!

3. If you need to do this:

   begin
     do_something
   rescue Exception => e
     critical_cleanup
     raise
   end
   

   you can actually do this:

   begin
     do_something
   ensure
     critical_cleanup
   end
   

   In the second case, critical cleanup will be called every time, whether or not an exception is thrown.

I came here because I needed to create a {{ render() }} function in Twig, to simulate Symfony2's behaviour. Rendering controllers from view is really cool to display independant widgets or ajax-reloadable stuffs.

Even if you're not a Twig user, you can still take this helper and use it as you want in your views to render a controller, using <?php echo twig_render('welcome/index', $param1, $param2, $_); ?>. This will echo everything your controller outputted.

Here it is:

helpers/twig_helper.php

<?php

if (!function_exists('twig_render'))
{

    function twig_render()
    {
        $args = func_get_args();
        $route = array_shift($args);
        $controller = APPPATH . 'controllers/' . substr($route, 0, strrpos($route, '/'));

        $explode = explode('/', $route);
        if (count($explode) < 2)
        {
            show_error("twig_render: A twig route is made from format: path/to/controller/action.");
        }

        if (!is_file($controller . '.php'))
        {
            show_error("twig_render: Controller not found: {$controller}");
        }
        if (!is_readable($controller . '.php'))
        {
            show_error("twig_render: Controller not readable: {$controller}");
        }
        require_once($controller . '.php');

        $class = ucfirst(reset(array_slice($explode, count($explode) - 2, 1)));
        if (!class_exists($class))
        {
            show_error("twig_render: Controller file exists, but class not found inside: {$class}");
        }

        $object = new $class();
        if (!($object instanceof CI_Controller))
        {
            show_error("twig_render: Class {$class} is not an instance of CI_Controller");
        }

        $method = $explode[count($explode) - 1];
        if (!method_exists($object, $method))
        {
            show_error("twig_render: Controller method not found: {$method}");
        }

        if (!is_callable(array($object, $method)))
        {
            show_error("twig_render: Controller method not visible: {$method}");
        }

        call_user_func_array(array($object, $method), $args);

        $ci = &get_instance();
        return $ci->output->get_output();
    }

}

Specific for Twig users (adapt this code to your Twig implementation):

libraries/Twig.php

$this->_twig_env->addFunction('render', new Twig_Function_Function('twig_render'));

Usage

{{ render('welcome/index', param1, param2, ...) }}

Looks like I'm late to the game, but this is a common question...

This is probably the code you want.

Please note that this code is in the public domain, from Usenet, MSDN, and the Excellerando blog.

Public Function ComputerName() As String
'' Returns the host name

'' Uses late-binding: bad for performance and stability, useful for 
'' code portability. The correct declaration is:

'   Dim objNetwork  As IWshRuntimeLibrary.WshNetwork
'   Set objNetwork = New IWshRuntimeLibrary.WshNetwork

    Dim objNetwork As Object
    Set objNetwork = CreateObject("WScript.Network")

    ComputerName = objNetwork.ComputerName
    
    Set objNetwork = Nothing

End Function

You'll probably need this, too:

Public Function UserName(Optional WithDomain As Boolean = False) As String
'' Returns the user's network name

'' Uses late-binding: bad for performance and stability, useful for
'' code portability. The correct declaration is:

'   Dim objNetwork  As IWshRuntimeLibrary.WshNetwork
'   Set objNetwork = New IWshRuntimeLibrary.WshNetwork


    Dim objNetwork As Object
    Set objNetwork = CreateObject("WScript.Network")

    If WithDomain Then
        UserName = objNetwork.UserDomain & "\" & objNetwork.UserName
    Else
        UserName = objNetwork.UserName
    End If
    
    Set objNetwork = Nothing

End Function

AttendStar created a free add-on that suppresses the print dialog box and removes all headers and footers for most versions of Firefox.

With that feature on you can use $('img').jqprint(); and jqprint for jquery will only print that image automatically called from your web application.

I tried following format, working fine

$ServerList = Get-Content "C:\ServerList.txt"
    $currentTrustHost=(get-item WSMan:\localhost\Client\TrustedHosts).value
    if ( ($currentTrustHost).Length -gt "0" ) {
        $currentTrustHost+= ,$ServerList
        set-item WSMan:\localhost\Client\TrustedHosts –value $currentTrustHost -Force -ErrorAction SilentlyContinue
        }
    else {
        $currentTrustHost+= $ServerList
        set-item WSMan:\localhost\Client\TrustedHosts –value $currentTrustHost -Force -ErrorAction SilentlyContinue
    }

The "-ErrorAction SilentlyContinue" is required in old PS version to avoid fake error message:

Java9 uses byte[] to store String.value, so you can only get about 1GB Strings in Java9. Java8 on the other hand can have 2GB Strings.

By character I mean "char"s, some character is not representable in BMP(like some of the emojis), so it will take more(currently 2) chars.

Using start works for me:

@echo off
copy "C:\Remoting.config-Training" "C:\Remoting.config"
start C:\ThirdParty.exe

EDIT: Ok, looking more closely, start seems to interpret the first parameter as the new window title if quoted. So, if you need to quote the path to your ThirdParty.exe you must supply a title string as well.

Examples:

:: Title not needed:
start C:\ThirdParty.exe

:: Title needed
start "Third Party App" "C:\Program Files\Vendor\ThirdParty.exe"
