All sprints are iterations but not all iterations are sprints. Iteration is a common term in iterative and incremental development (IID). Scrum is one specialized flavor of IID so it makes sense to specialize the terminology as well. It also helps brand the methodology different from other IID methodologies :)

As to the sprint length: anything goes as long as the sprint is timeboxed i.e. it is finished on the planned date and not "when it's ready". (Or alternatively, in rare occasions, the sprint is terminated prematurely to start a new sprint in case some essential boundary conditions are changed.)

It does help to have the sprints of similar durations. There's less to remember about the sprint schedule and your planning gets more accurate. I like to keep mine at 2 calendar weeks, which will resolve into 8..10 business days outside holiday seasons.

You can check out https://kanbanflow.com It's free for now because it's in beta and they say there is no time limit. It behaves very similar to AgileZen

I second the google doc, or you could use an online collaborative board that multiple people can edit.

Or you can host a more robust excel doc in skydrive from MS. I haven't tried that yet.

Mura.ly is another one that I am playing with currently. It has unlimited collaborators, though I think you would probably have to invite them everytime?? with a free account.

Hope that helps!

As is mentioned, Agile is a methodology, and there are various ways to define what agile is. To a large extent, if it involves constant unit testing and the ability to quickly adapt when the business needs change then it is probably agile. The opposite is the waterfall method.

There are various implementations that are codified by consultants, such as Xtremem Programming, Scrum and RUP (Rational Unified Process).

So, if you are using Scrum then you can switch between agile and scrum depending on if you are talking about the methodology or your implementation. You will want to see if the terms are being used correctly, by the context.

For example, if I am talking about the 15 min standup as part of my agile process, that is not necessarily needed to be agile, but scrum almost requires it, so when you interchange the terms, it is important to differentiate between the two concepts.

Scrum is just one of the many iterative and incremental agile software development methods. You can find here a very detailed description of the process.

In the SCRUM methodology, a Sprint is the basic unit of development. Each Sprint starts with a planning meeting, where the tasks for the sprint are identified and an estimated commitment for the sprint goal is made. A Sprint ends with a review or retrospective meeting where the progress is reviewed and lessons for the next sprint are identified. During each Sprint, the team creates finished portions of a Product.

In the Agile methods each iteration involves a team working through a full software development cycle, including planning, requirements analysis, design, coding, unit testing, and acceptance testing when a working product is demonstrated to stakeholders.

So if in a SCRUM Sprint you perform all the software development phases (from requirement analysis to acceptance testing), and in my opinion you should, you can say SCRUM Sprints correspond to AGILE Iterations.

Probably the most definitive is Figure B.1(d) of the ggplot2 book, the appendices of which are available at http://ggplot2.org/book/appendices.pdf.

However, it is not quite that simple. hjust and vjust as described there are how it works in geom_text and theme_text (sometimes). One way to think of it is to think of a box around the text, and where the reference point is in relation to that box, in units relative to the size of the box (and thus different for texts of different size). An hjust of 0.5 and a vjust of 0.5 center the box on the reference point. Reducing hjust moves the box right by an amount of the box width times 0.5-hjust. Thus when hjust=0, the left edge of the box is at the reference point. Increasing hjust moves the box left by an amount of the box width times hjust-0.5. When hjust=1, the box is moved half a box width left from centered, which puts the right edge on the reference point. If hjust=2, the right edge of the box is a box width left of the reference point (center is 2-0.5=1.5 box widths left of the reference point. For vertical, less is up and more is down. This is effectively what that Figure B.1(d) says, but it extrapolates beyond [0,1].

But, sometimes this doesn't work. For example

DF <- data.frame(x=c("a","b","cdefghijk","l"),y=1:4)
p <- ggplot(DF, aes(x,y)) + geom_point()

p + opts(axis.text.x=theme_text(vjust=0))
p + opts(axis.text.x=theme_text(vjust=1))
p + opts(axis.text.x=theme_text(vjust=2))

The three latter plots are identical. I don't know why that is. Also, if text is rotated, then it is more complicated. Consider

p + opts(axis.text.x=theme_text(hjust=0, angle=90))
p + opts(axis.text.x=theme_text(hjust=0.5 angle=90))
p + opts(axis.text.x=theme_text(hjust=1, angle=90))
p + opts(axis.text.x=theme_text(hjust=2, angle=90))

The first has the labels left justified (against the bottom), the second has them centered in some box so their centers line up, and the third has them right justified (so their right sides line up next to the axis). The last one, well, I can't explain in a coherent way. It has something to do with the size of the text, the size of the widest text, and I'm not sure what else.

You could also use INDEX MATCH, which is more "powerful" than vlookup. This would give you exactly what you are looking for:

You can decide to use a public observable list to store public data, or just create a public setter method to store data and retrieve from the corresponding controller

With the Entity Framework most of the time SaveChanges() is sufficient. This creates a transaction, or enlists in any ambient transaction, and does all the necessary work in that transaction.

Sometimes though the SaveChanges(false) + AcceptAllChanges() pairing is useful.

The most useful place for this is in situations where you want to do a distributed transaction across two different Contexts.

I.e. something like this (bad):

using (TransactionScope scope = new TransactionScope())
{
    //Do something with context1
    //Do something with context2

    //Save and discard changes
    context1.SaveChanges();

    //Save and discard changes
    context2.SaveChanges();

    //if we get here things are looking good.
    scope.Complete();
}

If context1.SaveChanges() succeeds but context2.SaveChanges() fails the whole distributed transaction is aborted. But unfortunately the Entity Framework has already discarded the changes on context1, so you can't replay or effectively log the failure.

But if you change your code to look like this:

using (TransactionScope scope = new TransactionScope())
{
    //Do something with context1
    //Do something with context2

    //Save Changes but don't discard yet
    context1.SaveChanges(false);

    //Save Changes but don't discard yet
    context2.SaveChanges(false);

    //if we get here things are looking good.
    scope.Complete();
    context1.AcceptAllChanges();
    context2.AcceptAllChanges();

}

While the call to SaveChanges(false) sends the necessary commands to the database, the context itself is not changed, so you can do it again if necessary, or you can interrogate the ObjectStateManager if you want.

This means if the transaction actually throws an exception you can compensate, by either re-trying or logging state of each contexts ObjectStateManager somewhere.

Update 3: Since Node 13, you can use either the .mjs extension, or set "type": "module" in your package.json. You don't need to use the --experimental-modules flag.

Update 2: Since Node 12, you can use either the .mjs extension, or set "type": "module" in your package.json. And you need to run node with the --experimental-modules flag.

Update: In Node 9, it is enabled behind a flag, and uses the .mjs extension.

node --experimental-modules my-app.mjs

While import is indeed part of ES6, it is unfortunately not yet supported in NodeJS by default, and has only very recently landed support in browsers.

See browser compat table on MDN and this Node issue.

From James M Snell's Update on ES6 Modules in Node.js (February 2017):

Work is in progress but it is going to take some time — We’re currently looking at around a year at least.

Until support shows up natively, you'll have to continue using classic require statements:

const express = require("express");

If you really want to use new ES6/7 features in NodeJS, you can compile it using Babel. Here's an example server.

You can also use apply with .get i.e.

w['female'] = w['female'].apply({'male':0, 'female':1}.get):

w = pd.DataFrame({'female':['female','male','female']})
print(w)

Dataframe w:

   female
0  female
1    male
2  female

Using apply to replace values from the dictionary:

w['female'] = w['female'].apply({'male':0, 'female':1}.get)
print(w)

Result:

   female
0       1
1       0
2       1 

Note: apply with dictionary should be used if all the possible values of the columns in the dataframe are defined in the dictionary else, it will have empty for those not defined in dictionary.

For Bootstrap 4, there are now spacing utilities so it's easier to change the height via padding on the nav links. This can be responsively applied only at specific breakpoints (ie: py-md-3). For example, on larger (md) screens, this nav is 120px high, then shrinks to normal height for the mobile menu. No extra CSS is needed..

<nav class="navbar navbar-fixed-top navbar-inverse bg-primary navbar-toggleable-md py-md-3">
    <button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navbarNav" aria-expanded="false" aria-label="Toggle navigation">
        <span class="navbar-toggler-icon"></span>
    </button>
    <a class="navbar-brand" href="#">Brand</a>
    <div class="navbar-collapse collapse" id="navbarNav">
        <ul class="navbar-nav">

    </div>
</nav>

I personally use the very good http://www.datejs.com/ library.

Docco here: http://code.google.com/p/datejs/wiki/APIDocumentation

You can use the following to get your Australian format and will validate the leap day 29/02/2012 and not 29/02/2011:

jQuery.validator.addMethod("australianDate", function(value, element) { 
    return Date.parseExact(value, "d/M/yyyy");
});

$("#myForm").validate({
   rules : {
      birth_date : { australianDate : true }
   }
});

I also use the masked input plugin to standardise the data http://digitalbush.com/projects/masked-input-plugin/

$("#birth_date").mask("99/99/9999");

Looks like your form is submitting which is the default behaviour, you can stop it with this:

<form action="" method="post" onsubmit="completeAndRedirect();return false;">

Hazar is right with his \t. Here's the full list of escape characters for C#:

\' for a single quote.

\" for a double quote.

\\ for a backslash.

\0 for a null character.

\a for an alert character.

\b for a backspace.

\f for a form feed.

\n for a new line.

\r for a carriage return.

\t for a horizontal tab.

\v for a vertical tab.

\uxxxx for a unicode character hex value (e.g. \u0020).

\x is the same as \u, but you don't need leading zeroes (e.g. \x20).

\Uxxxxxxxx for a unicode character hex value (longer form needed for generating surrogates).

In very short - in MVC Controler is aware of (controls) view, while in MVVM, ViewModel is unaware of who consumes it. ViewModel exposes its observable properties and actions to whoever might be interested in using it. That fact makes testing easier since there is no reference to UI within ViewModel.

Check this path:

C:\Program Files\Git\mingw64\libexec\git-core\git.exe

If you can't access the file and your os is any linux distro or mac os x then either of these commands should work:

sudo nano .bashrc

chmod 777 .bashrc 

it is worthless

I was looking to find the answer to this question too, but the accepted answer was breaking for me. Apparently using window.innerWidth isn't portable. It does work in some browsers, but I noticed Firefox didn't like it.

Gregg Tavares posted a great resource here that addresses this issue directly: http://webglfundamentals.org/webgl/lessons/webgl-anti-patterns.html (See anti-pattern #'s 3 and 4).

Using canvas.clientWidth instead of window.innerWidth seems to work nicely.

Here's Gregg's suggested render loop:

function resize() {
  var width = gl.canvas.clientWidth;
  var height = gl.canvas.clientHeight;
  if (gl.canvas.width != width ||
      gl.canvas.height != height) {
     gl.canvas.width = width;
     gl.canvas.height = height;
     return true;
  }
  return false;
}

var needToRender = true;  // draw at least once
function checkRender() {
   if (resize() || needToRender) {
     needToRender = false;
     drawStuff();
   }
   requestAnimationFrame(checkRender);
}
checkRender();

I became interested in the idea of an AI for this game containing no hard-coded intelligence (i.e no heuristics, scoring functions etc). The AI should "know" only the game rules, and "figure out" the game play. This is in contrast to most AIs (like the ones in this thread) where the game play is essentially brute force steered by a scoring function representing human understanding of the game.

AI Algorithm

I found a simple yet surprisingly good playing algorithm: To determine the next move for a given board, the AI plays the game in memory using random moves until the game is over. This is done several times while keeping track of the end game score. Then the average end score per starting move is calculated. The starting move with the highest average end score is chosen as the next move.

With just 100 runs (i.e in memory games) per move, the AI achieves the 2048 tile 80% of the times and the 4096 tile 50% of the times. Using 10000 runs gets the 2048 tile 100%, 70% for 4096 tile, and about 1% for the 8192 tile.

See it in action

The best achieved score is shown here:

An interesting fact about this algorithm is that while the random-play games are unsurprisingly quite bad, choosing the best (or least bad) move leads to very good game play: A typical AI game can reach 70000 points and last 3000 moves, yet the in-memory random play games from any given position yield an average of 340 additional points in about 40 extra moves before dying. (You can see this for yourself by running the AI and opening the debug console.)

This graph illustrates this point: The blue line shows the board score after each move. The red line shows the algorithm's best random-run end game score from that position. In essence, the red values are "pulling" the blue values upwards towards them, as they are the algorithm's best guess. It's interesting to see the red line is just a tiny bit above the blue line at each point, yet the blue line continues to increase more and more.

I find it quite surprising that the algorithm doesn't need to actually foresee good game play in order to chose the moves that produce it.

Searching later I found this algorithm might be classified as a Pure Monte Carlo Tree Search algorithm.

Implementation and Links

First I created a JavaScript version which can be seen in action here. This version can run 100's of runs in decent time. Open the console for extra info. (source)

Later, in order to play around some more I used @nneonneo highly optimized infrastructure and implemented my version in C++. This version allows for up to 100000 runs per move and even 1000000 if you have the patience. Building instructions provided. It runs in the console and also has a remote-control to play the web version. (source)

Results

Surprisingly, increasing the number of runs does not drastically improve the game play. There seems to be a limit to this strategy at around 80000 points with the 4096 tile and all the smaller ones, very close to the achieving the 8192 tile. Increasing the number of runs from 100 to 100000 increases the odds of getting to this score limit (from 5% to 40%) but not breaking through it.

Running 10000 runs with a temporary increase to 1000000 near critical positions managed to break this barrier less than 1% of the times achieving a max score of 129892 and the 8192 tile.

Improvements

After implementing this algorithm I tried many improvements including using the min or max scores, or a combination of min,max,and avg. I also tried using depth: Instead of trying K runs per move, I tried K moves per move list of a given length ("up,up,left" for example) and selecting the first move of the best scoring move list.

Later I implemented a scoring tree that took into account the conditional probability of being able to play a move after a given move list.

However, none of these ideas showed any real advantage over the simple first idea. I left the code for these ideas commented out in the C++ code.

I did add a "Deep Search" mechanism that increased the run number temporarily to 1000000 when any of the runs managed to accidentally reach the next highest tile. This offered a time improvement.

I'd be interested to hear if anyone has other improvement ideas that maintain the domain-independence of the AI.

2048 Variants and Clones

Just for fun, I've also implemented the AI as a bookmarklet, hooking into the game's controls. This allows the AI to work with the original game and many of its variants.

This is possible due to domain-independent nature of the AI. Some of the variants are quite distinct, such as the Hexagonal clone.

You have to set setOnItemLongClickListener() in the ListView:

lv.setOnItemLongClickListener(new OnItemLongClickListener() {
            @Override
            public boolean onItemLongClick(AdapterView<?> arg0, View arg1,
                    int pos, long id) {
                // TODO Auto-generated method stub

                Log.v("long clicked","pos: " + pos);

                return true;
            }
        }); 

The XML for each item in the list (should you use a custom XML) must have android:longClickable="true" as well (or you can use the convenience method lv.setLongClickable(true);). This way you can have a list with only some items responding to longclick.

Hope this will help you.

Use this command to update react npm install --save [email protected] Don't forget to change 16.12.0 to the latest version or the version you need to setup.

I'd have gone with

var myFoo = document.querySelectorAll("#myDiv > .foo");
var myDiv = myFoo.parentNode;

At one time, I remember seeing the MSDN library state to use CStr() because it was faster. I do not know if this is true though.

This is a problem with your remote. When you do git push origin master, origin is the remote and master is the branch you're pushing.

When you do this:

git remote

I bet the list does not include origin. To re-add the origin remote:

git remote add origin [email protected]:your_github_username/your_github_app.git

Or, if it exists but is formatted incorrectly:

git remote rm origin
git remote add origin [email protected]:your_github_username/your_github_app.git

word-wrap: break-word; 

add this to your container that should do the trick

You can't do it client-side. You'll have to do it on the server.

Edit: This answer is outdated!

As the time of this edit, HTML file API is now supported on all major browsers.

I'd provide an update with solution, but @mark.inman.winning already did it.

Keep in mind that even if it's now possible to validate on the client, you should still validate it on the server, though. All client side validations can be bypassed.

My solution was to avoid using NOW() when writing sql with your programming language, and substitute with a string. The problem with NOW() as you indicate is it includes current time. So to capture from the beginning of the query day (0 hour and minute) instead of:

r.date <= DATE_SUB(NOW(), INTERVAL 99 DAY)

I did (php):

$current_sql_date = date('Y-m-d 00:00:00');

in the sql:

$sql_x = "r.date <= DATE_SUB('$current_sql_date', INTERVAL 99 DAY)"

With that, you will be retrieving data from midnight of the given day

One can import the package then consult its help

import statsmodels
help(sm)

At the very bottom of the help there is a section FILE that indicates where this package was installed.

This solution was tested with at least matplotlib (3.1.2) and statsmodels (0.11.1) (python 3.8.2).

An alternative to services is to use the value store.

In the base of my app I added this

var agentApp = angular.module('rbAgent', ['ui.router', 'rbApp.tryGoal', 'rbApp.tryGoal.service', 'ui.bootstrap']);

agentApp.value('agentMemory',
    {
        contextId: '',
        sessionId: ''
    }
);
...

And then in my controller I just reference the value store. I don't think it holds thing if the user closes the browser.

angular.module('rbAgent')
.controller('AgentGoalListController', ['agentMemory', '$scope', '$rootScope', 'config', '$state', function(agentMemory, $scope, $rootScope, config, $state){

$scope.config = config;
$scope.contextId = agentMemory.contextId;
...

The check has to be like this:

if num == line.split()[0]:

If file.txt has a layout like this:

1 foo
20 bar
30 20

We split up "1 foo" into ['1', 'foo'] and just use the first item, which is the number.

In order to capture keystrokes in a Forms control, you must derive a new class that is based on the class of the control that you want, and you override the ProcessCmdKey().

protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
{
    //handle your keys here
}

Example :

protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
{
    //capture up arrow key
    if (keyData == Keys.Up )
    {
        MessageBox.Show("You pressed Up arrow key");
        return true;
    }

    return base.ProcessCmdKey(ref msg, keyData);
}

You can write if, else if, else statements in short form. For example:

Boolean isCapital = city.isCapital(); //Object Boolean (not boolean)
String isCapitalName = isCapital == null ? "" : isCapital ? "Capital" : "City";      

This is short form of:

Boolean isCapital = city.isCapital();
String isCapitalName;
if(isCapital == null) {
    isCapitalName = "";
} else if(isCapital) {
    isCapitalName = "Capital";
} else {
    isCapitalName = "City";
}

I think what you need is the below prototype

$(element).on('input',function(){code})

You could use a regex.

In your example that would be:

db.stuff.find( { foo: /^bar$/i } );

I must say, though, maybe you could just downcase (or upcase) the value on the way in rather than incurring the extra cost every time you find it. Obviously this wont work for people's names and such, but maybe use-cases like tags.

I think there's an even easier way now. This enables basic caching for all $http requests (which $resource inherits):

 var app = angular.module('myApp',[])
      .config(['$httpProvider', function ($httpProvider) {
            // enable http caching
           $httpProvider.defaults.cache = true;
      }])

Same problem for me on apache http client 4.5.5 adding default header

Connection: close

resolve the problem

You can continue using WebClient to POST (instead of GET, which is the HTTP verb you're currently using with DownloadString), but I think you'll find it easier to work with the (slightly) lower-level classes WebRequest and WebResponse.

There are two parts to this - the first is to post the login form, the second is recovering the "Set-cookie" header and sending that back to the server as "Cookie" along with your GET request. The server will use this cookie to identify you from now on (assuming it's using cookie-based authentication which I'm fairly confident it is as that page returns a Set-cookie header which includes "PHPSESSID").

POSTing to the login form

Form posts are easy to simulate, it's just a case of formatting your post data as follows:

field1=value1&field2=value2

Using WebRequest and code I adapted from Scott Hanselman, here's how you'd POST form data to your login form:

string formUrl = "http://www.mmoinn.com/index.do?PageModule=UsersAction&Action=UsersLogin"; // NOTE: This is the URL the form POSTs to, not the URL of the form (you can find this in the "action" attribute of the HTML's form tag
string formParams = string.Format("email_address={0}&password={1}", "your email", "your password");
string cookieHeader;
WebRequest req = WebRequest.Create(formUrl);
req.ContentType = "application/x-www-form-urlencoded";
req.Method = "POST";
byte[] bytes = Encoding.ASCII.GetBytes(formParams);
req.ContentLength = bytes.Length;
using (Stream os = req.GetRequestStream())
{
    os.Write(bytes, 0, bytes.Length);
}
WebResponse resp = req.GetResponse();
cookieHeader = resp.Headers["Set-cookie"];

Here's an example of what you should see in the Set-cookie header for your login form:

PHPSESSID=c4812cffcf2c45e0357a5a93c137642e; path=/; domain=.mmoinn.com,wowmine_referer=directenter; path=/; domain=.mmoinn.com,lang=en; path=/;domain=.mmoinn.com,adt_usertype=other,adt_host=-

GETting the page behind the login form

Now you can perform your GET request to a page that you need to be logged in for.

string pageSource;
string getUrl = "the url of the page behind the login";
WebRequest getRequest = WebRequest.Create(getUrl);
getRequest.Headers.Add("Cookie", cookieHeader);
WebResponse getResponse = getRequest.GetResponse();
using (StreamReader sr = new StreamReader(getResponse.GetResponseStream()))
{
    pageSource = sr.ReadToEnd();
}

EDIT:

If you need to view the results of the first POST, you can recover the HTML it returned with:

using (StreamReader sr = new StreamReader(resp.GetResponseStream()))
{
    pageSource = sr.ReadToEnd();
}

Place this directly below cookieHeader = resp.Headers["Set-cookie"]; and then inspect the string held in pageSource.

As you said, in MySQL USAGE is synonymous with "no privileges". From the MySQL Reference Manual:

The USAGE privilege specifier stands for "no privileges." It is used at the global level with GRANT to modify account attributes such as resource limits or SSL characteristics without affecting existing account privileges.

USAGE is a way to tell MySQL that an account exists without conferring any real privileges to that account. They merely have permission to use the MySQL server, hence USAGE. It corresponds to a row in the `mysql`.`user` table with no privileges set.

The IDENTIFIED BY clause indicates that a password is set for that user. How do we know a user is who they say they are? They identify themselves by sending the correct password for their account.

A user's password is one of those global level account attributes that isn't tied to a specific database or table. It also lives in the `mysql`.`user` table. If the user does not have any other privileges ON *.*, they are granted USAGE ON *.* and their password hash is displayed there. This is often a side effect of a CREATE USER statement. When a user is created in that way, they initially have no privileges so they are merely granted USAGE.

Check out Javascript's Array API for details on the exact syntax for Array methods. Modifying your code to use the correct syntax would be:

var array = [];
calendars.forEach(function(item) {
    array.push(item.id);
});

console.log(array);

You can also use the map() method to generate an Array filled with the results of calling the specified function on each element. Something like:

var array = calendars.map(function(item) {
    return item.id;
});

console.log(array);

And, since ECMAScript 2015 has been released, you may start seeing examples using let or const instead of var and the => syntax for creating functions. The following is equivalent to the previous example (except it may not be supported in older node versions):

let array = calendars.map(item => item.id);
console.log(array);

For ASP.NET5, i.e. ASPNETCORE, you can do the following in configure:

app.UseRequestLocalization(new RequestLocalizationOptions
{
    DefaultRequestCulture = new RequestCulture(new CultureInfo("en-gb")),
    SupportedCultures = new List<CultureInfo>
    {
        new CultureInfo("en-gb")
    },
            SupportedUICultures = new List<CultureInfo>
    {
        new CultureInfo("en-gb")
    }
});

Here's a series of blog posts that gives more information.

I've gotten very good results from the java.lang.instrument.Instrumentation approach mentioned in another answer. For good examples of its use, see the entry, Instrumentation Memory Counter from the JavaSpecialists' Newsletter and the java.sizeOf library on SourceForge.

You might want to look here and here.

A Little code example from the first link:

<?php
// include the SOAP classes
require_once('nusoap.php');
// define parameter array (ISBN number)
$param = array('isbn'=>'0385503954');
// define path to server application
$serverpath ='http://services.xmethods.net:80/soap/servlet/rpcrouter';
//define method namespace
$namespace="urn:xmethods-BNPriceCheck";
// create client object
$client = new soapclient($serverpath);
// make the call
$price = $client->call('getPrice',$param,$namespace);
// if a fault occurred, output error info
if (isset($fault)) {
        print "Error: ". $fault;
        }
else if ($price == -1) {
        print "The book is not in the database.";
} else {
        // otherwise output the result
        print "The price of book number ". $param[isbn] ." is $". $price;
        }
// kill object
unset($client);
?>

Less than or equal:

User.objects.filter(userprofile__level__lte=0)

Greater than or equal:

User.objects.filter(userprofile__level__gte=0)

Likewise, lt for less than and gt for greater than. You can find them all in the documentation.

This also balances HTML tags so that they won't be left open and doesn't break words.

add_filter("the_content", "break_text");
function break_text($text){
    $length = 500;
    if(strlen($text)<$length+10) return $text;//don't cut if too short

    $break_pos = strpos($text, ' ', $length);//find next space after desired length
    $visible = substr($text, 0, $break_pos);
    return balanceTags($visible) . " […]";
}

I answered a virtually identical question just the other day: Save CSV files into mysql database

MySQL has a feature LOAD DATA INFILE, which allows it to import a CSV file directly in a single SQL query, without needing it to be processed in a loop via your PHP program at all.

Simple example:

<?php
$query = <<<eof
    LOAD DATA INFILE '$fileName'
     INTO TABLE tableName
     FIELDS TERMINATED BY '|' OPTIONALLY ENCLOSED BY '"'
     LINES TERMINATED BY '\n'
    (field1,field2,field3,etc)
eof;

$db->query($query);
?>

It's as simple as that.

No loops, no fuss. And much much quicker than parsing it in PHP.

MySQL manual page here: http://dev.mysql.com/doc/refman/5.1/en/load-data.html

Hope that helps

I checked all the above solutions, they don't work. The only possible solution is to catch 'onkeydown' event for each input of the form. You need to attach disableAllInputs to onload of the page or via jquery ready()

/*
 * Prevents default behavior of pushing enter button. This method doesn't work,
 * if bind it to the 'onkeydown' of the document|form, or to the 'onkeypress' of
 * the input. So method should be attached directly to the input 'onkeydown'
 */
function preventEnterKey(e) {
    // W3C (Chrome|FF) || IE
    e = e || window.event;
    var keycode = e.which || e.keyCode;
    if (keycode == 13) { // Key code of enter button
        // Cancel default action
        if (e.preventDefault) { // W3C
            e.preventDefault();
        } else { // IE
            e.returnValue = false;
        }
        // Cancel visible action
        if (e.stopPropagation) { // W3C
            e.stopPropagation();
        } else { // IE
            e.cancelBubble = true;
        }
        // We don't need anything else
        return false;
    }
}
/* Disable enter key for all inputs of the document */
function disableAllInputs() {
    try {
        var els = document.getElementsByTagName('input');
        if (els) {
            for ( var i = 0; i < els.length; i++) {
                els[i].onkeydown = preventEnterKey;
            }

If you need to do a QQ plot of one sample vs. another, statsmodels includes qqplot_2samples(). Like Ricky Robinson in a comment above, this is what I think of as a QQ plot vs a probability plot which is a sample against a theoretical distribution.

http://statsmodels.sourceforge.net/devel/generated/statsmodels.graphics.gofplots.qqplot_2samples.html

I think you can't. The SELECT element is rendered at a point beyond the reach of CSS and HTML. Is it grayed out?

But you can try to add a "size" atribute.

On a MAC, you need to use nm *.o | c++filt, as there is no -C option in nm.

You can override symbols in the stock libraries by creating a library with the same symbols and specifying the library in LD_PRELOAD.

Some people use it to specify libraries in nonstandard locations, but LD_LIBRARY_PATH is better for that purpose.

You do it by setting a OnKeyListener on your EditText.

Here is a sample from my own code. I have an EditText named addCourseText, which will call the function addCourseFromTextBox when either the enter key or the d-pad is clicked.

addCourseText = (EditText) findViewById(R.id.clEtAddCourse);
addCourseText.setOnKeyListener(new OnKeyListener()
{
    public boolean onKey(View v, int keyCode, KeyEvent event)
    {
        if (event.getAction() == KeyEvent.ACTION_DOWN)
        {
            switch (keyCode)
            {
                case KeyEvent.KEYCODE_DPAD_CENTER:
                case KeyEvent.KEYCODE_ENTER:
                    addCourseFromTextBox();
                    return true;
                default:
                    break;
            }
        }
        return false;
    }
});

Though the event DOMSubtreeModified is deprecated, its working as of now, so for any makeshift projects you can use it as following.

$("body").on('DOMSubtreeModified', "#mydiv", function() {
    alert('changed');
});

In the long term though, you'll have to use the MutationObserver API.

You could host password in a repository and then just hide the page behind hidden address, that is derived from that password. This is not a very secure way, but it is simple.

Demonstration

You don't need to inject a DataSource in the JpaTransactionManager since the EntityManagerFactory already has a datasource. Try the following:

<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
   <property name="entityManagerFactory" ref="entityManagerFactory" />
</bean>

I can see that you have received many correct answers and very detailed one. I believe you are not testing it for very large prime numbers. And your only concern is to avoid printing intermediary prime number by your program.

A tiny change your program will do the trick.

Keep your logic same way and just pull out the print statement outside of loop. Break outer loop after n prime numbers.

import java.util.Scanner;
/**
 * Calculates the nth prime number
 * @author {Zyst}
 */
public class Prime {
    public static void main(String[] args) {

        Scanner input = new Scanner(System.in);
        int n, 
            i = 2, 
            x = 2;

        System.out.printf("This program calculates the nth Prime number\n");
        System.out.printf("Please enter the nth prime number you want to find:");
        n = input.nextInt();

        for(i = 2, x = 2; n > 0; i++) {
            for(x = 2; x < i; x++) {
                if(i % x == 0) {
                    break;
                }
            }
            if(x == i) {
                n--;
            }
        }
        System.out.printf("\n%d is prime", x);

    }
}

I needed a quick way to determine if the user connection speed was fast enough to enable/disable some features in a site I’m working on, I made this little script that averages the time it takes to download a single (small) image a number of times, it's working pretty accurately in my tests, being able to clearly distinguish between 3G or Wi-Fi for example, maybe someone can make a more elegant version or even a jQuery plugin.

var arrTimes = [];_x000D_
var i = 0; // start_x000D_

What you need is to map your array of objects and remember that every item will be an object, so that you will use for instance dot notation to take the values of the object.

In your component

 [
    {
        name: 'Sam',
        email: '[email protected]'
    },

    {
        name: 'Ash',
        email: '[email protected]'
    }
].map((anObjectMapped, index) => {
    return (
        <p key={`${anObjectMapped.name}_{anObjectMapped.email}`}>
            {anObjectMapped.name} - {anObjectMapped.email}
        </p>
    );
})

And remember when you put an array of jsx it has a different meaning and you can not just put object in your render method as you can put an array.

Take a look at my answer at mapping an array to jsx

If I'm correct, this is a bug in webkit (according to this). I'm not sure if there is much you can do, sorry for the weak answer.

There is, however, a work around which you can use. If you add the title attribute to your image (e.g. title="Image Not Found") it'll work.

you can done this way also.

if (dateFormat(first, "yyyy-mm-dd") > dateFormat(second, "yyyy-mm-dd")) {
        console.log("done");
}

OR

if (dateFormat(first, "mm-dd-yyyy") >  dateFormat(second, "mm-dd-yyyy")) {
        console.log("done");
}

            pad = function (val, len) {
                val = String(val);
                len = len || 2;
                while (val.length < len) val = "0" + val;
                return val;
            };

        // Regexes and supporting functions are cached through closure
        return function (date, mask, utc) {
            var dF = dateFormat;

            // You can't provide utc if you skip other args (use the "UTC:" mask prefix)
            if (arguments.length == 1 && Object.prototype.toString.call(date) == "[object String]" && !/\d/.test(date)) {
                mask = date;

I have the same problem (MSB3021) with WPF project in VS2008 (on Windows 7 x32). The problem appearing if i try to re-run application too quick after previous run. After a few minutes exe-file unlocked by itself and i can re-run application again. But such a long pause angers me. The only thing that really helped me was running VS as Administrator.

Install Adblock Plus, then add *.css rule in Filters options (custom filters tab). The method affect only on external stylesheets. It doesn't turn off inline styles.

Disable all external CSS

This method does exactly what you asked.

A better way: custom template filter: https://docs.djangoproject.com/en/dev/howto/custom-template-tags/

such as get my_list[x] in templates:

in template

{% load index %}
{{ my_list|index:x }}

templatetags/index.py

from django import template
register = template.Library()

@register.filter
def index(indexable, i):
    return indexable[i]

if my_list = [['a','b','c'], ['d','e','f']], you can use {{ my_list|index:x|index:y }} in template to get my_list[x][y]

It works fine with "for"

{{ my_list|index:forloop.counter0 }}

Tested and works well ^_^

In case it is not possible to bind the addTarget to your UITextField, I advise you to bind one of them as suggested above, and insert the code for execution at the end of the shouldChangeCharactersIn method.

nameTextField.addTarget(self, action: #selector(RegistrationViewController.textFieldDidChange(_:)), for: .editingChanged)

@objc func textFieldDidChange(_ textField: UITextField) {
    if phoneNumberTextField.text!.count == 17 && nameTextField.text!.count > 0 {
        continueButtonOutlet.backgroundColor = UIColor(.green)
    } else {
        continueButtonOutlet.backgroundColor = .systemGray
    }
}

And in call in shouldChangeCharactersIn func.

func textField(_ textField: UITextField, shouldChangeCharactersIn range: NSRange, replacementString string: String) -> Bool {

    guard let text = textField.text else {
        return true
    }
    let lastText = (text as NSString).replacingCharacters(in: range, with: string) as String

    if phoneNumberTextField == textField {
        textField.text = lastText.format("+7(NNN)-NNN-NN-NN", oldString: text)
        textFieldDidChange(phoneNumberTextField)
        return false
    }
    return true
}

You could also use vbCrLf which corresponds to Chr(13) & Chr(10).

Range("A1").value = Environ("Username")

This is better than Application.Username, which doesn't always supply the Windows username. Thanks to Kyle for pointing this out.

• Application Username is the name of the User set in Excel > Tools > Options
• Environ("Username") is the name you registered for Windows; see Control Panel >System

Add some jquery code, you need jquery to do this :

<script>
        $(".btn[data-toggle='collapse']").click(function() {
            if ($(this).text() == '+') {
                $(this).text('-');
            } else {
                $(this).text('+');
            }
        });
        </script>

Add any file in the documentation which will include your content, for example toc.h:

@ mainpage Manual SDK
<hr/>
@ section pageTOC Content
  -# @ref Description
  -# @ref License
  -# @ref Item
...

And in your Doxyfile:

INPUT = toc.h \

Example (in Russian):

• scale-tech.ru/luckyBackupW/doc/html/index.html (via web.archive.org)

• scale-tech.ru/luckyBackupW/doc/html/toc_8h_source.html (via web.archive.org)

For me it worked after removing the target folder

There are at least three places where you may find shared_ptr:

1. If your C++ implementation supports C++11 (or at least the C++11 shared_ptr), then std::shared_ptr will be defined in <memory>.

2. If your C++ implementation supports the C++ TR1 library extensions, then std::tr1::shared_ptr will likely be in <memory> (Microsoft Visual C++) or <tr1/memory> (g++'s libstdc++). Boost also provides a TR1 implementation that you can use.

3. Otherwise, you can obtain the Boost libraries and use boost::shared_ptr, which can be found in <boost/shared_ptr.hpp>.

If you're doing this in Drupal and use the Form API to change the #type from text to 'hidden' in hook_form_alter (for example), be advised that the output HTML will have different (or omitted) DIV wrappers, IDs and class names.

I found the following tutorial very useful.

Step1: The maven command used to create the web app: mvn archetype:generate -DgroupId=test.aasweb -DartifactId=TestWebApp -DarchetypeArtifactId=maven-archetype-webapp

Step2: The following entry was added onto the project's pom.xml.

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>2.0.2</version>
    <configuration>
    <source>1.6</source>
    <target>1.6</target>
    </configuration>
</plugin>

    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-eclipse-plugin</artifactId>
    <configuration>

Step3: Run the maven command to convert into eclipse project format. mvn eclipse:clean eclipse:eclipse

Step4: Import the project onto eclipse as Existing Maven project.

For Linux the easiest way to get is,

dpkg -l | grep "perl"

The RegExp constructor creates a regular expression object for matching text with a pattern.

    var pattern1 = ':\\(|:=\\(|:-\\(';
    var pattern2 = ':\\(|:=\\(|:-\\(|:\\(|:=\\(|:-\\(';
    var regex = new RegExp(pattern1 + '|' + pattern2, 'gi');
    str.match(regex);

Above code works perfectly for me...

With SimpleDateFormat. And steps are -

1. Create your date pattern string
2. Create SimpleDateFormat Object
3. And parse with it.
4. It will return Date Object.

Yes, I can give you the outline but my Python is a bit rusty and I'm too busy to explain in detail.

Basically, you need to put a proxy in the method that will call the original, eg:

 class fred(object):
   def blog(self):
     print "We Blog"


 class methCallLogger(object):
   def __init__(self, meth):
     self.meth = meth

   def __call__(self, code=None):
     self.meth()
     # would also log the fact that it invoked the method

 #example
 f = fred()
 f.blog = methCallLogger(f.blog)

This StackOverflow answer about callable may help you understand the above.

In more detail:

Although the answer was accepted, due to the interesting discussion with Glenn and having a few minutes free, I wanted to enlarge on my answer:

# helper class defined elsewhere
class methCallLogger(object):
   def __init__(self, meth):
     self.meth = meth
     self.was_called = False

   def __call__(self, code=None):
     self.meth()
     self.was_called = True

#example
class fred(object):
   def blog(self):
     print "We Blog"

f = fred()
g = fred()
f.blog = methCallLogger(f.blog)
g.blog = methCallLogger(g.blog)
f.blog()
assert(f.blog.was_called)
assert(not g.blog.was_called)

Those two parameters (or variants of) are sent, by convention, with all events.

• sender: The object which has raised the event
• e an instance of EventArgs including, in many cases, an object which inherits from EventArgs. Contains additional information about the event, and sometimes provides ability for code handling the event to alter the event somehow.

In the case of the events you mentioned, neither parameter is particularly useful. The is only ever one page raising the events, and the EventArgs are Empty as there is no further information about the event.

Looking at the 2 parameters separately, here are some examples where they are useful.

sender

Say you have multiple buttons on a form. These buttons could contain a Tag describing what clicking them should do. You could handle all the Click events with the same handler, and depending on the sender do something different

private void HandleButtonClick(object sender, EventArgs e)
{
    Button btn = (Button)sender;
    if(btn.Tag == "Hello")
      MessageBox.Show("Hello")
    else if(btn.Tag == "Goodbye")
       Application.Exit();
    // etc.
}

Disclaimer : That's a contrived example; don't do that!

e

Some events are cancelable. They send CancelEventArgs instead of EventArgs. This object adds a simple boolean property Cancel on the event args. Code handling this event can cancel the event:

private void HandleCancellableEvent(object sender, CancelEventArgs e)
{
    if(/* some condition*/)
    {
       // Cancel this event
       e.Cancel = true;
    }
}

Here is my contribution.
I will not try to list all tools/libraries/plugins that exist to take advantage of Docker with Maven. Some answers have already done it.
instead of, I will focus on applications typology and the Dockerfile way.
Dockerfile is really a simple and important concept of Docker (all known/public images rely on that) and I think that trying to avoid understanding and using Dockerfiles is not necessarily the better way to enter in the Docker world.

Dockerizing an application depends on the application itself and the goal to reach

1) For applications that we want to go on to run them on installed/standalone Java server (Tomcat, JBoss, etc...)

The road is harder and that is not the ideal target because that adds complexity (we have to manage/maintain the server) and it is less scalable and less fast than embedded servers in terms of build/deploy/undeploy.
But for legacy applications, that may considered as a first step.
Generally, the idea here is to define a Docker image for the server and to define an image per application to deploy.
The docker images for the applications produce the expected WAR/EAR but these are not executed as container and the image for the server application deploys the components produced by these images as deployed applications.
For huge applications (millions of line of codes) with a lot of legacy stuffs, and so hard to migrate to a full spring boot embedded solution, that is really a nice improvement.
I will not detail more that approach since that is for minor use cases of Docker but I wanted to expose the overall idea of that approach because I think that for developers facing to these complex cases, it is great to know that some doors are opened to integrate Docker.

2) For applications that embed/bootstrap the server themselves (Spring Boot with server embedded : Tomcat, Netty, Jetty...)

That is the ideal target with Docker. I specified Spring Boot because that is a really nice framework to do that and that has also a very high level of maintainability but in theory we could use any other Java way to achieve that.
Generally, the idea here is to define a Docker image per application to deploy.
The docker images for the applications produce a JAR or a set of JAR/classes/configuration files and these start a JVM with the application (java command) when we create and start a container from these images.
For new applications or applications not too complex to migrate, that way has to be favored over standalone servers because that is the standard way and the most efficient way of using containers.
I will detail that approach.

Dockerizing a maven application

1) Without Spring Boot

The idea is to create a fat jar with Maven (the maven assembly plugin and the maven shade plugin help for that) that contains both the compiled classes of the application and needed maven dependencies.
Then we can identify two cases :

• if the application is a desktop or autonomous application (that doesn't need to be deployed on a server) : we could specify as CMD/ENTRYPOINT in the Dockerfile the java execution of the application : java -cp .:/fooPath/* -jar myJar

• if the application is a server application, for example Tomcat, the idea is the same : to get a fat jar of the application and to run a JVM in the CMD/ENTRYPOINT. But here with an important difference : we need to include some logic and specific libraries (org.apache.tomcat.embed libraries and some others) that starts the embedded server when the main application is started.
  We have a comprehensive guide on the heroku website.
  For the first case (autonomous application), that is a straight and efficient way to use Docker.
  For the second case (server application), that works but that is not straight, may be error prone and is not a very extensible model because you don't place your application in the frame of a mature framework such as Spring Boot that does many of these things for you and also provides a high level of extension.
  But that has a advantage : you have a high level of freedom because you use directly the embedded Tomcat API.

2) With Spring Boot

At last, here we go.
That is both simple, efficient and very well documented.
There are really several approaches to make a Maven/Spring Boot application to run on Docker.
Exposing all of them would be long and maybe boring.
The best choice depends on your requirement.
But whatever the way, the build strategy in terms of docker layers looks like the same.
We want to use a multi stage build : one relying on Maven for the dependency resolution and for build and another one relying on JDK or JRE to start the application.

Build stage (Maven image) :

• pom copy to the image
• dependencies and plugins downloads.
  About that, mvn dependency:resolve-plugins chained to mvn dependency:resolve may do the job but not always.
  Why ? Because these plugins and the package execution to package the fat jar may rely on different artifacts/plugins and even for a same artifact/plugin, these may still pull a different version. So a safer approach while potentially slower is resolving dependencies by executing exactly the mvn command used to package the application (which will pull exactly dependencies that you are need) but by skipping the source compilation and by deleting the target folder to make the processing faster and to prevent any undesirable layer change detection for that step.
• source code copy to the image
• package the application

Run stage (JDK or JRE image) :

• copy the jar from the previous stage

Here two examples.

a) A simple way without cache for downloaded maven dependencies

Dockerfile :

########Maven build stage########
FROM maven:3.6-jdk-11 as maven_build
WORKDIR /app

#copy pom
COPY pom.xml .

#resolve maven dependencies
RUN mvn clean package -Dmaven.test.skip -Dmaven.main.skip -Dspring-boot.repackage.skip && rm -r target/

#copy source
COPY src ./src

# build the app (no dependency download here)
RUN mvn clean package  -Dmaven.test.skip

# split the built app into multiple layers to improve layer rebuild
RUN mkdir -p target/docker-packaging && cd target/docker-packaging && jar -xf ../my-app*.jar

########JRE run stage########
FROM openjdk:11.0-jre
WORKDIR /app

#copy built app layer by layer
ARG DOCKER_PACKAGING_DIR=/app/target/docker-packaging
COPY --from=maven_build ${DOCKER_PACKAGING_DIR}/BOOT-INF/lib /app/lib
COPY --from=maven_build ${DOCKER_PACKAGING_DIR}/BOOT-INF/classes /app/classes
COPY --from=maven_build ${DOCKER_PACKAGING_DIR}/META-INF /app/META-INF

#run the app
CMD java -cp .:classes:lib/* \
         -Djava.security.egd=file:/dev/./urandom \
         foo.bar.MySpringBootApplication

Drawback of that solution ? Any changes in the pom.xml means re-creates the whole layer that download and stores the maven dependencies. That is generally not acceptable for applications with many dependencies (and Spring Boot pulls many dependencies), overall if you don't use a maven repository manager during the image build.

b) A more efficient way with cache for maven dependencies downloaded

The approach is here the same but maven dependencies downloads that are cached in the docker builder cache.
The cache operation relies on buildkit (experimental api of docker).
To enable buildkit, the env variable DOCKER_BUILDKIT=1 has to be set (you can do that where you want : .bashrc, command line, docker daemon json file...).

Dockerfile :

# syntax=docker/dockerfile:experimental

########Maven build stage########
FROM maven:3.6-jdk-11 as maven_build
WORKDIR /app

#copy pom
COPY pom.xml .

#copy source
COPY src ./src

# build the app (no dependency download here)
RUN --mount=type=cache,target=/root/.m2  mvn clean package -Dmaven.test.skip

# split the built app into multiple layers to improve layer rebuild
RUN mkdir -p target/docker-packaging && cd target/docker-packaging && jar -xf ../my-app*.jar

########JRE run stage########
FROM openjdk:11.0-jre
WORKDIR /app

#copy built app layer by layer
ARG DOCKER_PACKAGING_DIR=/app/target/docker-packaging
COPY --from=maven_build ${DOCKER_PACKAGING_DIR}/BOOT-INF/lib /app/lib
COPY --from=maven_build ${DOCKER_PACKAGING_DIR}/BOOT-INF/classes /app/classes
COPY --from=maven_build ${DOCKER_PACKAGING_DIR}/META-INF /app/META-INF

#run the app
CMD java -cp .:classes:lib/* \
         -Djava.security.egd=file:/dev/./urandom \
         foo.bar.MySpringBootApplication

I landed here because of an XCTestCase, in which I'd disabled most of the tests by prefixing them with 'no_' as in no_testBackgroundAdding. Once I noticed that most of the answers had something to do with locks and threading, I realized the test contained a few instances of XCTestExpectation with corresponding waitForExpectations. They were all in the disabled tests, but apparently Xcode was still evaluating them at some level.

In the end I found an XCTestExpectation that was defined as @property but lacked the @synthesize. Once I added the synthesize directive, the EXC_BAD_INSTRUCTION disappeared.

Throwing an exception that's exclusive to null arguments (whether NullPointerException or a custom type) makes automated null testing more reliable. This automated testing can be done with reflection and a set of default values, as in Guava's NullPointerTester. For example, NullPointerTester would attempt to call the following method...

Foo(String string, List<?> list) {
  checkArgument(string.length() > 0);
  // missing null check for list!
  this.string = string;
  this.list = list;
}

...with two lists of arguments: "", null and null, ImmutableList.of(). It would test that each of these calls throws the expected NullPointerException. For this implementation, passing a null list does not produce NullPointerException. It does, however, happen to produce an IllegalArgumentException because NullPointerTester happens to use a default string of "". If NullPointerTester expects only NullPointerException for null values, it catches the bug. If it expects IllegalArgumentException, it misses it.

Most probably it has to do with caching on the device. Catching the exception and ignoring is not nice but my problem was fixed and it seems to work.

There's no native Django management command to drop all tables. Both sqlclear and reset require an app name.

However, you can install Django Extensions which gives you manage.py reset_db, which does exactly what you want (and gives you access to many more useful management commands).

My complete code as below is working well:

package ripon.java.mail;
import java.util.*;
import javax.mail.*;
import javax.mail.internet.*;

public class SendEmail
{
public static void main(String [] args)
{    
    // Sender's email ID needs to be mentioned
     String from = "[email protected]";
     String pass ="test123";
    // Recipient's email ID needs to be mentioned.
   String to = "[email protected]";

   String host = "smtp.gmail.com";

   // Get system properties
   Properties properties = System.getProperties();
   // Setup mail server
   properties.put("mail.smtp.starttls.enable", "true");
   properties.put("mail.smtp.host", host);
   properties.put("mail.smtp.user", from);
   properties.put("mail.smtp.password", pass);
   properties.put("mail.smtp.port", "587");
   properties.put("mail.smtp.auth", "true");

   // Get the default Session object.
   Session session = Session.getDefaultInstance(properties);

   try{
      // Create a default MimeMessage object.
      MimeMessage message = new MimeMessage(session);

      // Set From: header field of the header.
      message.setFrom(new InternetAddress(from));

      // Set To: header field of the header.
      message.addRecipient(Message.RecipientType.TO,
                               new InternetAddress(to));

      // Set Subject: header field
      message.setSubject("This is the Subject Line!");

      // Now set the actual message
      message.setText("This is actual message");

      // Send message
      Transport transport = session.getTransport("smtp");
      transport.connect(host, from, pass);
      transport.sendMessage(message, message.getAllRecipients());
      transport.close();
      System.out.println("Sent message successfully....");
   }catch (MessagingException mex) {
      mex.printStackTrace();
   }
}
}

For me this problem was caused by a missing ) at the end of an if statement in a function called by the function the error was reported as from. Try scrolling up in the output to find the first error reported by the compiler. Fixing that error may fix this error.

If you have compatibility with Object.keys, and node does have compatibility, you should use that for sure.

However, if you do not have compatibility, and for any reason using a loop function is out of the question - like me, I used the following solution:

JSON.stringify(obj) === '{}'

Consider this solution a 'last resort' use only if must.

See in the comments "there are many ways in which this solution is not ideal".

I had a last resort scenario, and it worked perfectly.

Here on a openSuse 12.3 the solution was installing the 32-bit version of libaio in addition. Oracle seems to need this now, although on 12.1 it run without the 32-bit version.

My team were experiencing these issues intermittently with long running SSIS packages. This has been happening since Windows server patching.

Our SSIS and SQL servers are on separate VM servers.

Working with our Wintel Servers team we rebooted both servers and for the moment, the problem appears to have gone away.

The engineer has said that they're unsure if the issue is the patches or new VMTools that they updated at the same time. We'll monitor for now and if the timeout problems recur, they'll try rolling back the VMXNET3 driver, first, then if that doesn't work, take off the June Rollup patches.

So for us the issue is nothing to do with our SQL Queries (we're loading billions of new rows so it has to be long running).

I suggest you to see "How do I run a bat file in the background from another bat file?"

Also, good answer (of using start command) was given in "Parallel execution of shell processes" question page here;

But my recommendation is to use PowerShell. I believe it will perfectly suit your needs.

If you want to reinstall packages specified in a requirements.txt file, without upgrading, so just reinstall the specific versions specified in the requirements.txt file:

pip install -r requirements.txt --ignore-installed

There are also these 'ways':

>>> dict.fromkeys(range(1, 4))
{1: None, 2: None, 3: None}
>>> dict(zip(range(1, 4), range(1, 4)))
{1: 1, 2: 2, 3: 3}

For Asp.Net MVC

@Html.ListBox("parameterName", ViewBag.ParameterValueList as MultiSelectList, 
 new { 
 @class = "chosen-select form-control"
 }) 

or

  @Html.ListBoxFor(model => model.parameterName,
  ViewBag.ParameterValueList as MultiSelectList,
   new{
       data_placeholder = "Select Options ",
       @class = "chosen-select form-control"
   })

You probably got a conflict in something that you haven't staged for commit. git won't let you commit things independently (because it's all part of the merge, I guess), so you need to git add that file and then git commit -m "Merge conflict resolution". The -i flag for git commit does the add for you.

In Windows, with GetFileInformationByHandleEx, passing FileNameInfo, you can retrieve the file name.

I think using okhttp is the easiest solution. Here you can see an example for POST method, sending a json, and with auth.

val url = "https://example.com/endpoint"

val client = OkHttpClient()

val JSON = MediaType.get("application/json; charset=utf-8")
val body = RequestBody.create(JSON, "{\"data\":\"$data\"}")
val request = Request.Builder()
        .addHeader("Authorization", "Bearer $token")
        .url(url)
        .post(body)
        .build()

val  response = client . newCall (request).execute()

println(response.request())
println(response.body()!!.string())

Remember to add this dependency to your project https://mvnrepository.com/artifact/com.squareup.okhttp3/okhttp

UPDATE: July 7th, 2019 I'm gonna give two examples using latest Kotlin (1.3.41), OkHttp (4.0.0) and Jackson (2.9.9).

In SP2013 Online, I tried the filter conditions as Name Contains Folder_I_want_to_list

This showed me all the folders containing the Name in their file path. It lists even sub-folder contents which wasn't available when i tried Name equal to Folder_I_want_to_list

There newer ways to connect Node.js and C++. Please, loot at Nan.

EDIT The fastest and easiest way is nbind. If you want to write asynchronous add-on you can combine Asyncworker class from nan.

There are two interfaces

1. org.springframework.web.context.request.WebRequest
2. org.springframework.web.context.request.NativeWebRequest

Allows for generic request parameter access as well as request/session attribute access, without ties to the native Servlet/Portlet API.

Ex.:

@RequestMapping(value = "/", method = GET)
public List<T> getAll(WebRequest webRequest){
    Map<String, String[]> params = webRequest.getParameterMap();
    //...
}

P.S. There are Docs about arguments which can be used as Controller params.

This works in all browsers:

window.location.href = '...';

If you wanted to change the page without it reflecting in the browser back history, you can do:

window.location.replace('...');

First of all, never use a for in loop to enumerate over an array. Never. Use good old for(var i = 0; i<arr.length; i++).

The reason behind this is the following: each object in JavaScript has a special field called prototype. Everything you add to that field is going to be accessible on every object of that type. Suppose you want all arrays to have a cool new function called filter_0 that will filter zeroes out.

Array.prototype.filter_0 = function() {
    var res = [];
    for (var i = 0; i < this.length; i++) {
        if (this[i] != 0) {
            res.push(this[i]);
        }
    }
    return res;
};

console.log([0, 5, 0, 3, 0, 1, 0].filter_0());
//prints [5,3,1]

This is a standard way to extend objects and add new methods. Lots of libraries do this. However, let's look at how for in works now:

var listeners = ["a", "b", "c"];
for (o in listeners) {
    console.log(o);
}
//prints:
//  0
//  1
//  2
//  filter_0

Do you see? It suddenly thinks filter_0 is another array index. Of course, it is not really a numeric index, but for in enumerates through object fields, not just numeric indexes. So we're now enumerating through every numeric index and filter_0. But filter_0 is not a field of any particular array object, every array object has this property now.

Luckily, all objects have a hasOwnProperty method, which checks if this field really belongs to the object itself or if it is simply inherited from the prototype chain and thus belongs to all the objects of that type.

for (o in listeners) {
    if (listeners.hasOwnProperty(o)) {
       console.log(o);
    }
}
 //prints:
 //  0
 //  1
 //  2

Note, that although this code works as expected for arrays, you should never, never, use for in and for each in for arrays. Remember that for in enumerates the fields of an object, not array indexes or values.

var listeners = ["a", "b", "c"];
listeners.happy = "Happy debugging";

for (o in listeners) {
    if (listeners.hasOwnProperty(o)) {
       console.log(o);
    }
}

 //prints:
 //  0
 //  1
 //  2
 //  happy

This has worked for me:

let webApiUrl = 'example.com/getStuff';
let tokenStr = 'xxyyzz';
axios.get(webApiUrl, { headers: {"Authorization" : `Bearer ${tokenStr}`} });

in /etc/my.cnf:

[mysqld]
...

performance_schema = 0

table_cache = 0
table_definition_cache = 0
max-connect-errors = 10000

query_cache_size = 0
query_cache_limit = 0

...

Good work on server with 256MB Memory.

The accepted answer still threw a Javascript error in IE for me (for Angular 1.2 at least). It is a bug but the workaround is to use ngAttr detailed on https://docs.angularjs.org/guide/interpolation

<input type="text" ng-model="inputText" ng-attr-placeholder="{{somePlaceholder}}" />

Issue: https://github.com/angular/angular.js/issues/5025

As far as I know you can use all mentioned technologies separately or together. It's up to you. I think you look at the problem from the wrong angle. Material Design is just the way particular elements of the page are designed, behave and put together. Material Design provides great UI/UX, but it relies on the graphic layout (HTML/CSS) rather than JS (events, interactions).

On the other hand, AngularJS and Bootstrap are front-end frameworks that can speed up your development by saving you from writing tons of code. For example, you can build web app utilizing AngularJS, but without Material Design. Or You can build simple HTML5 web page with Material Design without AngularJS or Bootstrap. Finally you can build web app that uses AngularJS with Bootstrap and with Material Design. This is the best scenario. All technologies support each other.

1. Bootstrap = responsive page
2. AngularJS = MVC
3. Material Design = great UI/UX

You can check awesome material design components for AngularJS:

https://material.angularjs.org

Demo: https://material.angularjs.org/latest/demo/

You want to use absolute positioning.

An absolute position element is positioned relative to the first parent element that has a position other than static. If no such element is found, the containing block is html

For instance :

.yourDiv{
  position:absolute;
  top: 123px;
}

To get it to work, the parent needs to be relative (position:relative)

In your case this should do the trick:

.suggestionsBox{position:absolute; top:40px;}
#specific_locations_add{position:relative;}

I stumbled upon the same problem and for some reason the --stdin option was not available on the version of passwd I was using (shipped in Ubuntu 14.04).

If any of you happen to experience the same issue, you can work it around as I did, by using the chpasswd command like this:

echo "<user>:<password>" | chpasswd

You can do it like:

val df = sqlContext.emptyDataFrame
if( df.eq(sqlContext.emptyDataFrame) )
    println("empty df ")
else 
    println("normal df")

• %lu for unsigned long
• %llu for unsigned long long

This can be installed via conda with the command conda install -c anaconda python=3.7 as per https://anaconda.org/anaconda/python.

Though not all packages support 3.7 yet, running conda update --all may resolve some dependency failures.

I think that it should be:

$path = 'myfolder/myimage.png';
$type = pathinfo($path, PATHINFO_EXTENSION);
$data = file_get_contents($path);
$base64 = 'data:image/' . $type . ';base64,' . base64_encode($data);

I just came across this, while looking for something else.

I would recommend to go with the methods in the os package. This is because you can make it more general, compensating for any weird case.

You can do something like:

import os

the_file = 'aaaa/bbbb/ccc.ddd'

extensions_list = ['ddd', 'eee', 'fff']

if os.path.splitext(the_file)[-1] in extensions_list:
    # Do your thing.

Use LIKE ANY(ARRAY['AAA%', 'BBB%', 'CCC%']) as per this cool trick @maniek showed earlier today.

Try something like this inside ThisOutlookSession:

Private Sub Application_NewMail()
    Call Your_main_macro
End Sub

My outlook vba just fired when I received an email and had that application event open.

Edit: I just tested a hello world msg box and it ran after being called in the application_newmail event when an email was received.

Though this is old, I think question is valid even today

My suspicion is that aud should refer to the resource server(s), and the client_id should refer to one of the client applications recognized by the authentication server

Yes, aud should refer to token consuming party. And client_id refers to token obtaining party.

In my current case, my resource server is also my web app client.

In the OP's scenario, web app and resource server both belongs to same party. So this means client and audience to be same. But there can be situations where this is not the case.

Think about a SPA which consume an OAuth protected resource. In this scenario SPA is the client. Protected resource is the audience of access token.

This second scenario is interesting. There is a working draft in place named "Resource Indicators for OAuth 2.0" which explain where you can define the intended audience in your authorisation request. So the resulting token will restricted to the specified audience. Also, Azure OIDC use a similar approach where it allows resource registration and allow auth request to contain resource parameter to define access token intended audience. Such mechanisms allow OAuth adpotations to have a separation between client and token consuming (audience) party.

The Best and easy Way is to create this method And Pass Array And Value:

- (NSArray *) filter:(NSArray *)array where:(NSString *)key is:(id)value{
    NSMutableArray *temArr=[[NSMutableArray alloc] init];
    for(NSDictionary *dic in self)
        if([dic[key] isEqual:value])
            [temArr addObject:dic];
    return temArr;
}

There is package called rimraf that is very handy. It is the UNIX command rm -rf for node.

Nevertheless, it can be too powerful too because you can delete folders very easily using it. The following commands will delete the files inside the folder. If you remove the *, you will remove the log folder.

const rimraf = require('rimraf');
rimraf('./log/*', function () { console.log('done'); });

https://www.npmjs.com/package/rimraf

One set of familiar operations that you can do in MapReduce is the set of normal SQL operations: SELECT, SELECT WHERE, GROUP BY, ect.

Another good example is matrix multiply, where you pass one row of M and the entire vector x and compute one element of M * x.

You need to increase the timeout on your connection. If you can't or don't want to do that for some reason, you could try calling:

data = db.query(sql).store_result()

This will fetch all the results immediately, then your connection won't time out halfway through iterating over them.

This is my favorite solution for SQL 2008 , which puts the results into a "TEST" temp table that I can use to sort and get the results that I need :

SET NOCOUNT ON 
DBCC UPDATEUSAGE(0) 
DROP TABLE #t;
CREATE TABLE #t 
( 
[name] NVARCHAR(128),
[rows] CHAR(11),
reserved VARCHAR(18), 
data VARCHAR(18), 
index_size VARCHAR(18),
unused VARCHAR(18)
) ;
INSERT #t EXEC sp_msForEachTable 'EXEC sp_spaceused ''?''' 
SELECT * INTO TEST FROM #t;
DROP TABLE #t;
SELECT  name, [rows], reserved, data, index_size, unused FROM TEST \
WHERE ([rows] > 0) AND (name LIKE 'XXX%')

Write someMethod() in this way:

public void someMethod() {

    SomeClass.AnotherClass.MyEnum enumExample = SomeClass.AnotherClass.MyEnum.VALUE_A;

    switch (enumExample) {
    case VALUE_A:
        break;
    }

}

In switch statement you must use the constant name only.

If you have been given a database file and have not installed the correct server (either SQLite or MySQL), try this tool: https://dbconvert.com/sqlite/mysql/ The trial version allows converting the first 50 records of each table, the rest of the data is watermarked. This is a Windows program, and can either dump into a running database server, or can dump output to a .sql file

If you're not locked on MySQL you can switch to PostgreSQL. It supports JavaScript procedures (PL/V8) inside the database. It is very fast and powerful. Checkout this post.

In a command prompt:

$ git --version

To be highly positive you work with the actual email body (yet, still with the possibility you're not parsing the right part), you have to skip attachments, and focus on the plain or html part (depending on your needs) for further processing.

As the before-mentioned attachments can and very often are of text/plain or text/html part, this non-bullet-proof sample skips those by checking the content-disposition header:

b = email.message_from_string(a)
body = ""

if b.is_multipart():
    for part in b.walk():
        ctype = part.get_content_type()
        cdispo = str(part.get('Content-Disposition'))

        # skip any text/plain (txt) attachments
        if ctype == 'text/plain' and 'attachment' not in cdispo:
            body = part.get_payload(decode=True)  # decode
            break
# not multipart - i.e. plain text, no attachments, keeping fingers crossed
else:
    body = b.get_payload(decode=True)

BTW, walk() iterates marvelously on mime parts, and get_payload(decode=True) does the dirty work on decoding base64 etc. for you.

Some background - as I implied, the wonderful world of MIME emails presents a lot of pitfalls of "wrongly" finding the message body. In the simplest case it's in the sole "text/plain" part and get_payload() is very tempting, but we don't live in a simple world - it's often surrounded in multipart/alternative, related, mixed etc. content. Wikipedia describes it tightly - MIME, but considering all these cases below are valid - and common - one has to consider safety nets all around:

Very common - pretty much what you get in normal editor (Gmail,Outlook) sending formatted text with an attachment:

multipart/mixed
 |
 +- multipart/related
 |   |
 |   +- multipart/alternative
 |   |   |
 |   |   +- text/plain
 |   |   +- text/html
 |   |      
 |   +- image/png
 |
 +-- application/msexcel

Relatively simple - just alternative representation:

multipart/alternative
 |
 +- text/plain
 +- text/html

For good or bad, this structure is also valid:

multipart/alternative
 |
 +- text/plain
 +- multipart/related
      |
      +- text/html
      +- image/jpeg

Hope this helps a bit.

P.S. My point is don't approach email lightly - it bites when you least expect it :)

I would use a variant of @steamer25 's approach. The point is that I prefer to obtain the last sourced script even when my session was started through Rscript. The following snippet, when included on a file, will provided a variable thisScript containing the normalized path of the script. I confess the (ab)use of source'ing, so sometimes I invoke Rscript and the script provided in the --file argument sources another script that sources another one... Someday I will invest in making my messy code turns into a package.

thisScript <- (function() {
  lastScriptSourced <- tail(unlist(lapply(sys.frames(), function(env) env$ofile)), 1)

  if (is.null(lastScriptSourced)) {
    # No script sourced, checking invocation through Rscript
    cmdArgs <- commandArgs(trailingOnly = FALSE)
    needle <- "--file="
    match <- grep(needle, cmdArgs)
    if (length(match) > 0) {
      return(normalizePath(sub(needle, "", cmdArgs[match]), winslash=.Platform$file.sep, mustWork=TRUE))
    }
  } else {
    # 'source'd via R console
    return(normalizePath(lastScriptSourced, winslash=.Platform$file.sep, mustWork=TRUE))
  }
})()

This is python regex, but it probably works in other languages that implement it, too.

I guess it depends on what you consider a character to be. If it's letters, numbers, and underscores:

\w{3,}

if just letters and digits:

[a-zA-Z0-9]{3,}

Python also has a regex method to return all matches from a string.

>>> import re
>>> re.findall(r'\w{3,}', 'This is a long string, yes it is.')
['This', 'long', 'string', 'yes']

You miss parenthesis:

var value: string = dataObjects[i].getValue(); 
var id: number = dataObjects[i].getId();

If you use Java Web Start (you can start applications from any URL, even the local file system) it will take care of finding the right version for your application.

If you don't need to worry about scientific or other expressions of numbers and are only working with strings that could be numbers with or without a period:

Function

def is_float(s):
    result = False
    if s.count(".") == 1:
        if s.replace(".", "").isdigit():
            result = True
    return result

Lambda version

is_float = lambda x: x.replace('.','',1).isdigit() and "." in x

Example

if is_float(some_string):
    some_string = float(some_string)
elif some_string.isdigit():
    some_string = int(some_string)
else:
    print "Does not convert to int or float."

This way you aren't accidentally converting what should be an int, into a float.

Well nobody answered - which is in part the fault of the question : the input string contains eleven fields (this much can be inferred) but how many tabs ? Most possibly exactly 10. Then the answer is

String s = "\t2\t\t4\t5\t6\t\t8\t\t10\t";
String[] fields = s.split("\t", -1);  // in your case s.split("\t", 11) might also do
for (int i = 0; i < fields.length; ++i) {
    if ("".equals(fields[i])) fields[i] = null;
}
System.out.println(Arrays.asList(fields));
// [null, 2, null, 4, 5, 6, null, 8, null, 10, null]
// with s.split("\t") : [null, 2, null, 4, 5, 6, null, 8, null, 10]

If the fields happen to contain tabs this won't work as expected, of course.
The -1 means : apply the pattern as many times as needed - so trailing fields (the 11th) will be preserved (as empty strings ("") if absent, which need to be turned to null explicitly).

If on the other hand there are no tabs for the missing fields - so "5\t6" is a valid input string containing the fields 5,6 only - there is no way to get the fields[] via split.

You can try this methods

window.open(location, '_self').close();

Language features:

Templates and Generic Code

• Template argument deduction for class templates

  • Like how functions deduce template arguments, now constructors can deduce the template arguments of the class
  • http://wg21.link/p0433r2 http://wg21.link/p0620r0 http://wg21.link/p0512r0

• template <auto>

  • Represents a value of any (non-type template argument) type.

• Non-type template arguments fixes

• template<template<class...>typename bob> struct foo {}

• ( Folding + ... + expressions ) and Revisions

• auto x{8}; is an int

• modernizing using with ... and lists

Lambda

• constexpr lambdas

  • Lambdas are implicitly constexpr if they qualify

• Capturing *this in lambdas

  • [*this]{ std::cout << could << " be " << useful << '\n'; }

Attributes

• [[fallthrough]], [[nodiscard]], [[maybe_unused]] attributes

• [[attributes]] on namespaces and enum { erator[[s]] }

• using in attributes to avoid having to repeat an attribute namespace.

• Compilers are now required to ignore non-standard attributes they don't recognize.

  • The C++14 wording allowed compilers to reject unknown scoped attributes.

Syntax cleanup

• Inline variables

  • Like inline functions
  • Compiler picks where the instance is instantiated
  • Deprecate static constexpr redeclaration, now implicitly inline.

• namespace A::B

• Simple static_assert(expression); with no string

• no throw unless throw(), and throw() is noexcept(true).

Cleaner multi-return and flow control

• Structured bindings

  • Basically, first-class std::tie with auto
  • Example:
    • const auto [it, inserted] = map.insert( {"foo", bar} );
    • Creates variables it and inserted with deduced type from the pair that map::insert returns.
  • Works with tuple/pair-likes & std::arrays and relatively flat structs
  • Actually named structured bindings in standard

• if (init; condition) and switch (init; condition)

  • if (const auto [it, inserted] = map.insert( {"foo", bar} ); inserted)
  • Extends the if(decl) to cases where decl isn't convertible-to-bool sensibly.

• Generalizing range-based for loops

  • Appears to be mostly support for sentinels, or end iterators that are not the same type as begin iterators, which helps with null-terminated loops and the like.

• if constexpr

  • Much requested feature to simplify almost-generic code.

Misc

• Hexadecimal float point literals

• Dynamic memory allocation for over-aligned data

• Guaranteed copy elision

  • Finally!
  • Not in all cases, but distinguishes syntax where you are "just creating something" that was called elision, from "genuine elision".

• Fixed order-of-evaluation for (some) expressions with some modifications

  • Not including function arguments, but function argument evaluation interleaving now banned
  • Makes a bunch of broken code work mostly, and makes .then on future work.

• Direct list-initialization of enums

• Forward progress guarantees (FPG) (also, FPGs for parallel algorithms)

  • I think this is saying "the implementation may not stall threads forever"?

• u8'U', u8'T', u8'F', u8'8' character literals (string already existed)

• "noexcept" in the type system

• __has_include

  • Test if a header file include would be an error
  • makes migrating from experimental to std almost seamless

• Arrays of pointer conversion fixes

• inherited constructors fixes to some corner cases (see P0136R0 for examples of behavior changes)

• aggregate initialization with inheritance.

• std::launder, type punning, etc

Library additions:

Data types

• std::variant<Ts...>

  • Almost-always non-empty last I checked?
  • Tagged union type
  • {awesome|useful}

• std::optional

  • Maybe holds one of something
  • Ridiculously useful

• std::any

  • Holds one of anything (that is copyable)

• std::string_view

  • std::string like reference-to-character-array or substring
  • Never take a string const& again. Also can make parsing a bajillion times faster.
  • "hello world"sv
  • constexpr char_traits

• std::byte off more than they could chew.

  • Neither an integer nor a character, just data

Invoke stuff

• std::invoke
  • Call any callable (function pointer, function, member pointer) with one syntax. From the standard INVOKE concept.
• std::apply
  • Takes a function-like and a tuple, and unpacks the tuple into the call.

• std::make_from_tuple, std::apply applied to object construction

• is_invocable, is_invocable_r, invoke_result

  • http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2016/p0077r2.html
  • http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2017/p0604r0.html
  • Deprecates result_of
  • is_invocable<Foo(Args...), R> is "can you call Foo with Args... and get something compatible with R", where R=void is default.
  • invoke_result<Foo, Args...> is std::result_of_t<Foo(Args...)> but apparently less confusing?

Isocpp.org has has an independent list of changes since C++14; it has been partly pillaged.

Naturally TS work continues in parallel, so there are some TS that are not-quite-ripe that will have to wait for the next iteration. The target for the next iteration is C++20 as previously planned, not C++19 as some rumors implied. C++1O has been avoided.

Initial list taken from this reddit post and this reddit post, with links added via googling or from the above isocpp.org page.

Additional entries pillaged from SD-6 feature-test list.

clang's feature list and library feature list are next to be pillaged. This doesn't seem to be reliable, as it is C++1z, not C++17.

these slides had some features missing elsewhere.

While "what was removed" was not asked, here is a short list of a few things ((mostly?) previous deprecated) that are removed in C++17 from C++:

Removed:

• register, keyword reserved for future use
• bool b; ++b;
• trigraphs
  • if you still need them, they are now part of your source file encoding, not part of language
• ios aliases
• auto_ptr, old <functional> stuff, random_shuffle
• allocators in std::function

There were rewordings. I am unsure if these have any impact on code, or if they are just cleanups in the standard:

Papers not yet integrated into above:

• P0505R0 (constexpr chrono)

• P0418R2 (atomic tweaks)

• P0512R0 (template argument deduction tweaks)

• P0490R0 (structured binding tweaks)

• P0513R0 (changes to std::hash)

• P0502R0 (parallel exceptions)

• P0509R1 (updating restrictions on exception handling)

• P0012R1 (make exception specifications be part of the type system)

• P0510R0 (restrictions on variants)

• P0504R0 (tags for optional/variant/any)

• P0497R0 (shared ptr tweaks)

• P0508R0 (structured bindings node handles)

• P0521R0 (shared pointer use count and unique changes?)

Spec changes:

• exception specs and throw expressions

Assuming your input is a standard null-terminated C string, you want to use strchr:

#include <string.h>

char* foo = "abcdefghijkl";
if (strchr(foo, 'a') != NULL)
{
  // do stuff
}

If on the other hand your array is not null-terminated (i.e. just raw data), you'll need to use memchr and provide a size:

#include <string.h>

char foo[] = { 'a', 'b', 'c', 'd', 'e' }; // note last element isn't '\0'
if (memchr(foo, 'a', sizeof(foo)))
{
  // do stuff
}

Try the Export Wizard. In this example I select a whole table, but you can just as easily specify a query:

(you can also specify a query here)

I have found the creates option in the command module useful. How about this:

- name: Move foo to bar
  command: creates="path/to/bar" mv /path/to/foo /path/to/bar

I used to do a 2 task approach using stat like Bruce P suggests. Now I do this as one task with creates. I think this is a lot clearer.

You've started right - now you just need to fill the each student structure in the array:

struct student
{
    public int s_id;
    public String s_name, c_name, dob;
}
class Program
{
    static void Main(string[] args)
    {
        student[] arr = new student[4];

        for(int i = 0; i < 4; i++)
        {
            Console.WriteLine("Please enter StudentId, StudentName, CourseName, Date-Of-Birth");


            arr[i].s_id = Int32.Parse(Console.ReadLine());
            arr[i].s_name = Console.ReadLine();
            arr[i].c_name = Console.ReadLine();
            arr[i].s_dob = Console.ReadLine();
       }
    }
}

Now, just iterate once again and write these information to the console. I will let you do that, and I will let you try to make program to take any number of students, and not just 4.

How about if you're copying each column in a sheet to different sheets? Example: row B of mysheet to row B of sheet1, row C of mysheet to row B of sheet 2...

Probably because you had something like this?

Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);                        
Uri fileUri =  CommonUtilities.getTBCameraOutputMediaFileUri();                  
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);                        
startActivityForResult(takePictureIntent, 2);

However you must not put the extra output into the intent, because then the data goes into the URI instead of the data variable. For that reason, you have to take the two lines in the middle out, so that you have

Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(takePictureIntent, 2);

That´s what caused the problem for me, hope that helped.

java.time

The answer by MadProgrammer is correct, especially the tip about Joda-Time. The successor to Joda-Time is now built into Java 8 as the new java.time package. Here's example code in Java 8.

When working with date-time (as opposed to local date), the time zone in critical. The day-of-month depends on the time zone. For example, the India time zone is +05:30 (five and a half hours ahead of UTC), while France is only one hour ahead. So a moment in a new day in India has one date while the same moment in France has “yesterday’s” date. Creating string output lacking any time zone or offset information is creating ambiguity. You asked for YYYY-MM-DD output so I provided, but I don't recommend it. Instead of ISO_LOCAL_DATE I would have used ISO_DATE to get this output: 2014-02-25+05:30

ZoneId zoneId = ZoneId.of( "Asia/Kolkata" );
ZonedDateTime zonedDateTime = ZonedDateTime.now( zoneId );

DateTimeFormatter formatterOutput = DateTimeFormatter.ISO_LOCAL_DATE; // Caution: The "LOCAL" part means we are losing time zone information, creating ambiguity.
String output = formatterOutput.format( zonedDateTime );

Dump to console…

System.out.println( "zonedDateTime: " + zonedDateTime );
System.out.println( "output: " + output );

When run…

zonedDateTime: 2014-02-25T14:22:20.919+05:30[Asia/Kolkata]
output: 2014-02-25

Joda-Time

Similar code using the Joda-Time library, the precursor to java.time.

DateTimeZone zone = new DateTimeZone( "Asia/Kolkata" );
DateTime dateTime = DateTime.now( zone );
DateTimeFormatter formatter = ISODateTimeFormat.date();
String output = formatter.print( dateTime );

ISO 8601

By the way, that format of your input string is a standard format, one of several handy date-time string formats defined by ISO 8601.

Both Joda-Time and java.time use ISO 8601 formats by default when parsing and generating string representations of various date-time values.

Big difference between an image and an iframe is the fact that an image keeps its aspect-ratio. You could combine an image and an iframe with will result in a responsive iframe. Hope this answerers your question.

Check this link for example : http://jsfiddle.net/Masau/7WRHM/

HTML:

<div class="wrapper">
    <div class="h_iframe">
        <!-- a transparent image is preferable -->
        <img class="ratio" src="http://placehold.it/16x9"/>
        <iframe src="http://www.youtube.com/embed/WsFWhL4Y84Y" frameborder="0" allowfullscreen></iframe>
    </div>
    <p>Please scale the "result" window to notice the effect.</p>
</div>

CSS:

html,body        {height:100%;}
.wrapper         {width:80%;height:100%;margin:0 auto;background:#CCC}
.h_iframe        {position:relative;}
.h_iframe .ratio {display:block;width:100%;height:auto;}
.h_iframe iframe {position:absolute;top:0;left:0;width:100%; height:100%;}

note: This only works with a fixed aspect-ratio.

Yes you can. I've used it with Word and PowerPoint. You will need Office 2010 client apps and SharePoint 2010 foundation at least. You must also allow editing without checking out on the document library.

It's quite cool, you can mark regions as 'locked' so no-one can change them and you can see what other people have changed every time you save your changes to the server. You also get to see who's working on the document from the Office app. The merging happens on SharePoint 2010.

I have JSONObject like this: {"status":[{"Response":"success"}]}.

If I want to convert the JSONObject value, which is a JSONArray into JSONObject automatically without using any static value, here is the code for that.

JSONArray array=new JSONArray();
JSONObject obj2=new JSONObject();
obj2.put("Response", "success");
array.put(obj2);
JSONObject obj=new JSONObject();
obj.put("status",array);

Converting the JSONArray to JSON Object:

Iterator<String> it=obj.keys();
        while(it.hasNext()){
String keys=it.next();
JSONObject innerJson=new JSONObject(obj.toString());
JSONArray innerArray=innerJson.getJSONArray(keys);
for(int i=0;i<innerArray.length();i++){
JSONObject innInnerObj=innerArray.getJSONObject(i);
Iterator<String> InnerIterator=innInnerObj.keys();
while(InnerIterator.hasNext()){
System.out.println("InnInnerObject value is :"+innInnerObj.get(InnerIterator.next()));


 }
}

Look at array_intersect().

$containsSearch = count(array_intersect($search_this, $all)) == count($search_this);

(This explanation is only for positive numbers since it depends on the language otherwise)

Definition

The Modulus is the remainder of the euclidean division of one number by another. % is called the modulo operation.

For instance, 9 divided by 4 equals 2 but it remains 1. Here, 9 / 4 = 2 and 9 % 4 = 1.

In your example: 5 divided by 7 gives 0 but it remains 5 (5 % 7 == 5).

Calculation

The modulo operation can be calculated using this equation:

a % b = a - floor(a / b) * b

• floor(a / b) represents the number of times you can divide a by b
• floor(a / b) * b is the amount that was successfully shared entirely
• The total (a) minus what was shared equals the remainder of the division

Applied to the last example, this gives:

5 % 7 = 5 - floor(5 / 7) * 7 = 5

Modular Arithmetic

That said, your intuition was that it could be -2 and not 5. Actually, in modular arithmetic, -2 = 5 (mod 7) because it exists k in Z such that 7k - 2 = 5.

You may not have learned modular arithmetic, but you have probably used angles and know that -90° is the same as 270° because it is modulo 360. It's similar, it wraps! So take a circle, and say that it's perimeter is 7. Then you read where is 5. And if you try with 10, it should be at 3 because 10 % 7 is 3.

FWIW, it smells like an error (or at least a potential source of future pain) to be using files from /usr/include when cross-compiling.

You can use this code snippet for creating a two buttoned Alert box,

import 'package:flutter/material.dart';

class BaseAlertDialog extends StatelessWidget {

  //When creating please recheck 'context' if there is an error!

  Color _color = Color.fromARGB(220, 117, 218 ,255);

  String _title;
  String _content;
  String _yes;
  String _no;
  Function _yesOnPressed;
  Function _noOnPressed;

  BaseAlertDialog({String title, String content, Function yesOnPressed, Function noOnPressed, String yes = "Yes", String no = "No"}){
    this._title = title;
    this._content = content;
    this._yesOnPressed = yesOnPressed;
    this._noOnPressed = noOnPressed;
    this._yes = yes;
    this._no = no;
  }

  @override
  Widget build(BuildContext context) {
    return AlertDialog(
      title: new Text(this._title),
      content: new Text(this._content),
      backgroundColor: this._color,
      shape:
          RoundedRectangleBorder(borderRadius: new BorderRadius.circular(15)),
      actions: <Widget>[
        new FlatButton(
          child: new Text(this._yes),
          textColor: Colors.greenAccent,
          onPressed: () {
            this._yesOnPressed();
          },
        ),
        new FlatButton(
          child: Text(this._no),
          textColor: Colors.redAccent,
          onPressed: () {
            this._noOnPressed();
          },
        ),
      ],
    );
  }
}

To show the dialog you can have a method that calls it NB after importing BaseAlertDialog class

_confirmRegister() {
var baseDialog = BaseAlertDialog(
    title: "Confirm Registration",
    content: "I Agree that the information provided is correct",
    yesOnPressed: () {},
    noOnPressed: () {},
    yes: "Agree",
    no: "Cancel");
showDialog(context: context, builder: (BuildContext context) => baseDialog);
}

OUTPUT WILL BE LIKE THIS

/* My lawyer told me not to reveal */

There was a requirement to get status and cpu / memory usage of some specific windows servers. I used below script:

This is an example of Windows Search Service.

  $cpu = Get-WmiObject win32_processor
  $search = get-service "WSearch"
  if ($search.Status -eq 'Running')
  {
  $searchmem = Get-WmiObject Win32_Service -Filter "Name = 'WSearch'"
  $searchid = $searchmem.ProcessID
  $searchcpu1 = Get-WmiObject Win32_PerfRawData_PerfProc_Process | Where {$_.IDProcess -eq $searchid}
  Start-Sleep -Seconds 1
  $searchcpu2 = Get-WmiObject Win32_PerfRawData_PerfProc_Process | Where {$_.IDProcess -eq $searchid}
  $searchp2p1 = $searchcpu2.PercentProcessorTime - $searchcpu1.PercentProcessorTime
  $searcht2t1 = $searchcpu2.Timestamp_Sys100NS - $searchcpu1.Timestamp_Sys100NS
  $searchcpu = [Math]::Round(($searchp2p1 / $searcht2t1 * 100) /$cpu.NumberOfLogicalProcessors, 1)
  $searchmem = [Math]::Round($searchcpu1.WorkingSetPrivate / 1mb,1)
  Write-Host 'Service is' $search.Status', Memory consumed: '$searchmem' MB, CPU Usage: '$searchcpu' %'
  }

  else
  {
  Write-Host Service is $search.Status -BackgroundColor Red
  }

This makes a nice Function....

cp -R t1/ t2

The trailing slash on the source directory changes the semantics slightly, so it copies the contents but not the directory itself. It also avoids the problems with globbing and invisible files that Bertrand's answer has (copying t1/* misses invisible files, copying `t1/* t1/.*' copies t1/. and t1/.., which you don't want).

I have copied the relevant code below from This page. Hope this might help you.

$.ajax({
  xhr: function() {
    var xhr = new window.XMLHttpRequest();
    //Upload progress
    xhr.upload.addEventListener("progress", function(evt) {
      if (evt.lengthComputable) {
        var percentComplete = evt.loaded / evt.total;
        //Do something with upload progress
        console.log(percentComplete);
      }
    }, false);
    //Download progress
    xhr.addEventListener("progress", function(evt) {
      if (evt.lengthComputable) {
        var percentComplete = evt.loaded / evt.total;
        //Do something with download progress
        console.log(percentComplete);
      }
    }, false);
    return xhr;
  },
  type: 'POST',
  url: "/",
  data: {},
  success: function(data) {
    //Do something success-ish
  }
});

$encoded_data = base64_encode(file_get_contents('path-to-your-image.jpg'));    

You don't have all digit characters in your string. So you have to split by space

QString Abcd = "123.5 Kb";
Abcd.split(" ")[0].toInt();    //convert the first part to Int
Abcd.split(" ")[0].toDouble(); //convert the first part to double
Abcd.split(" ")[0].toFloat();  //convert the first part to float

Update: I am updating an old answer. That was a straight forward answer to the specific question, with a strict assumption. However as noted by @DomTomCat in comments and @Mikhail in answer, In general one should always check whether the operation is successful or not. So using a boolean flag is necessary.

bool flag;
double v = Abcd.split(" ")[0].toDouble(&flag); 
if(flag){
  // use v
}

Also if you are taking that string as user input, then you should also be doubtful about whether the string is really splitable with space. If there is a possibility that the assumption may break then a regex verifier is more preferable. A regex like the following will extract the floating point value and the prefix character of 'b'. Then you can safely convert the captured strings to double.

([0-9]*\.?[0-9]+)\s+(\w[bB])

You can have an utility function like the following

QPair<double, QString> split_size_str(const QString& str){
    QRegExp regex("([0-9]*\\.?[0-9]+)\\s+(\\w[bB])");
    int pos = regex.indexIn(str);
    QStringList captures = regex.capturedTexts();
    if(captures.count() > 1){
        double value = captures[1].toDouble(); // should succeed as regex matched
        QString unit = captures[2]; // should succeed as regex matched
        return qMakePair(value, unit);
    }
    return qMakePair(0.0f, QString());
}

Commenting on Ken Bertelson solution and answering Jan Hettich:

How it works

the takes_ary_as_arg descTable[@] optsTable[@] line in try_with_local_arys() function sends:

1. This is actually creates a copy of the descTable and optsTable arrays which are accessible to the takes_ary_as_arg function.
2. takes_ary_as_arg() function receives descTable[@] and optsTable[@] as strings, that means $1 == descTable[@] and $2 == optsTable[@].

3. in the beginning of takes_ary_as_arg() function it uses ${!parameter} syntax, which is called indirect reference or sometimes double referenced, this means that instead of using $1's value, we use the value of the expanded value of $1, example:

   baba=booba
   variable=baba
   echo ${variable} # baba
   echo ${!variable} # booba
   

   likewise for $2.

4. putting this in argAry1=("${!1}") creates argAry1 as an array (the brackets following =) with the expanded descTable[@], just like writing there argAry1=("${descTable[@]}") directly. the declare there is not required.

N.B.: It is worth mentioning that array initialization using this bracket form initializes the new array according to the IFS or Internal Field Separator which is by default tab, newline and space. in that case, since it used [@] notation each element is seen by itself as if he was quoted (contrary to [*]).

My reservation with it

In BASH, local variable scope is the current function and every child function called from it, this translates to the fact that takes_ary_as_arg() function "sees" those descTable[@] and optsTable[@] arrays, thus it is working (see above explanation).

Being that case, why not directly look at those variables themselves? It is just like writing there:

argAry1=("${descTable[@]}")

See above explanation, which just copies descTable[@] array's values according to the current IFS.

In summary

This is passing, in essence, nothing by value - as usual.

I also want to emphasize Dennis Williamson comment above: sparse arrays (arrays without all the keys defines - with "holes" in them) will not work as expected - we would loose the keys and "condense" the array.

That being said, I do see the value for generalization, functions thus can get the arrays (or copies) without knowing the names:

• for ~"copies": this technique is good enough, just need to keep aware, that the indices (keys) are gone.

• for real copies: we can use an eval for the keys, for example:

  eval local keys=(\${!$1})
  

and then a loop using them to create a copy. Note: here ! is not used it's previous indirect/double evaluation, but rather in array context it returns the array indices (keys).

• and, of course, if we were to pass descTable and optsTable strings (without [@]), we could use the array itself (as in by reference) with eval. for a generic function that accepts arrays.

Depends on where the file you are trying to include from is located.

Example:

/rootdir/pages/file.php

/someotherDir/index.php

If you wrote the following in index.php: include('/rootdir/pages/file.php');it would error becuase it would try to get:

/someotherDir/rootdir/pages/file.php Which of course doesn't exist...

So you would have to use include('../rootdir/pages/file.php');

Here is a middle of the road approach that doesn't rely on any external libraries. I use list comprehension to exclude overlaps between abbreviations and terminators as well as to exclude overlaps between variations on terminations, for example: '.' vs. '."'

abbreviations = {'dr.': 'doctor', 'mr.': 'mister', 'bro.': 'brother', 'bro': 'brother', 'mrs.': 'mistress', 'ms.': 'miss', 'jr.': 'junior', 'sr.': 'senior',
                 'i.e.': 'for example', 'e.g.': 'for example', 'vs.': 'versus'}
terminators = ['.', '!', '?']
wrappers = ['"', "'", ')', ']', '}']


def find_sentences(paragraph):
   end = True
   sentences = []
   while end > -1:
       end = find_sentence_end(paragraph)
       if end > -1:
           sentences.append(paragraph[end:].strip())
           paragraph = paragraph[:end]
   sentences.append(paragraph)
   sentences.reverse()
   return sentences


def find_sentence_end(paragraph):
    [possible_endings, contraction_locations] = [[], []]
    contractions = abbreviations.keys()
    sentence_terminators = terminators + [terminator + wrapper for wrapper in wrappers for terminator in terminators]
    for sentence_terminator in sentence_terminators:
        t_indices = list(find_all(paragraph, sentence_terminator))
        possible_endings.extend(([] if not len(t_indices) else [[i, len(sentence_terminator)] for i in t_indices]))
    for contraction in contractions:
        c_indices = list(find_all(paragraph, contraction))
        contraction_locations.extend(([] if not len(c_indices) else [i + len(contraction) for i in c_indices]))
    possible_endings = [pe for pe in possible_endings if pe[0] + pe[1] not in contraction_locations]
    if len(paragraph) in [pe[0] + pe[1] for pe in possible_endings]:
        max_end_start = max([pe[0] for pe in possible_endings])
        possible_endings = [pe for pe in possible_endings if pe[0] != max_end_start]
    possible_endings = [pe[0] + pe[1] for pe in possible_endings if sum(pe) > len(paragraph) or (sum(pe) < len(paragraph) and paragraph[sum(pe)] == ' ')]
    end = (-1 if not len(possible_endings) else max(possible_endings))
    return end


def find_all(a_str, sub):
    start = 0
    while True:
        start = a_str.find(sub, start)
        if start == -1:
            return
        yield start
        start += len(sub)

I used Karl's find_all function from this entry: Find all occurrences of a substring in Python

For using scroll view along with Relative layout :

I don't know of any JVM that actually checks the JAVA_OPTS environment variable. Usually this is used in scripts which launch the JVM and they usually just add it to the java command-line.

The key thing to understand here is that arguments to java that come before the -jar analyse.jar bit will only affect the JVM and won't be passed along to your program. So, modifying the java line in your script to:

java $JAVA_OPTS -jar analyse.jar $*

Should "just work".

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

and you leave it null (0) when persisting. (null if you use the Integer / Long wrappers)

In some cases the AUTO strategy is resolved to SEQUENCE rathen than to IDENTITY or TABLE, so you might want to manually set it to IDENTITY or TABLE (depending on the underlying database).

It seems SEQUENCE + specifying the sequence name worked for you.

Iterating over a dictionary object itself actually gives you an iterator over its keys. Python is trying to unpack keys, which you get from m.type + m.purity into (m, k).

My crystal ball says m.type and m.purity are both strings, so your keys are also strings. Strings are iterable, so they can be unpacked; but iterating over the string gives you an iterator over its characters. So whenever m.type + m.purity is more than two characters long, you have too many values to unpack. (And whenever it's shorter, you have too few values to unpack.)

To fix this, you can iterate explicitly over the items of the dict, which are the (key, value) pairs that you seem to be expecting. But if you only want the values, then just use the values.

(In 2.x, itervalues, iterkeys, and iteritems are typically a better idea; the non-iter versions create a new list object containing the values/keys/items. For large dictionaries and trivial tasks within the iteration, this can be a lot slower than the iter versions which just set up an iterator.)

Well, you are having a valid access token to access your information and not others( this is because you got logged in and you have given permission to access your information). But the picture owner has not done the same (logged in + permission ) and so you are getting a violation error.

To obtain permission see this link and decide what kind of informations you want from any user and decide the permissions. Later on embed this in your code. (In the login function call)

In situations when you consider using things like exec 2>&1 I find easier to read if possible rewriting code using bash functions like this:

function myfunc(){
  [...]
}

myfunc &>mylog.log

You could use :

int a = 12;
if (a>0 || a<0){
cout << "Your text"<<endl;
}

I'm pretty sure it works.

This may do the trick:

import sys
if sys.version_info[0] > 2:
    # py3k
    pass
else:
    # py2
    import codecs
    import warnings
    def open(file, mode='r', buffering=-1, encoding=None,
             errors=None, newline=None, closefd=True, opener=None):
        if newline is not None:
            warnings.warn('newline is not supported in py2')
        if not closefd:
            warnings.warn('closefd is not supported in py2')
        if opener is not None:
            warnings.warn('opener is not supported in py2')
        return codecs.open(filename=file, mode=mode, encoding=encoding,
                    errors=errors, buffering=buffering)

Then you can keep you code in the python3 way.

Note that some APIs like newline, closefd, opener do not work

Because wrapper version does not support 11+ you can make simple trick to cheat newer version of InteliJ forever.

  press3x Shift -> type "Switch Boot JDK" -> and change for java 8. 

https://blog.jetbrains.com/idea/2015/05/intellij-idea-14-1-4-eap-141-1192-is-available/

Or If you want to work with java 11+ you simply have to update wrapper version to 4.8+

When you get the error message, you have the option to click on "Debug": this will lead you to the line where the error occurred. The Dark Canuck seems to be right, and I guess the error occurs on the line:

Sheets("Sheet1").protect Password:="btfd"

because most probably the "Sheet1" does not exist. However, if you say "It works fine, but when I save the file I get the message: run-time error '9': subscription out of range" it makes me think the error occurs on the second line:

ActiveWorkbook.Save

Could you please check this by pressing the Debug button first? And most important, as Gordon Bell says, why are you using a macro to protect a workbook?

My workaround was to use [style.display]="getControlsOnStyleDisplay()" instead of *ngIf="controlsOn". The block is there but it is not displayed.

@Component({
selector: 'app',
template:  `
    <controls [style.display]="getControlsOnStyleDisplay()"></controls>
...

export class AppComponent {
  @ViewChild(ControlsComponent) controls:ControlsComponent;

  controlsOn:boolean = false;

  getControlsOnStyleDisplay() {
    if(this.controlsOn) {
      return "block";
    } else {
      return "none";
    }
  }
....

So long as Excel can open the file, the functionality to change the format of the opened file is built in.

To convert an .html file, open it using Excel (File - Open) and then save it as a .xlsx file from Excel (File - Save as).

To do it using VBA, the code would look like this:

Sub Open_HTML_Save_XLSX()

    Workbooks.Open Filename:="C:\Temp\Example.html"
    ActiveWorkbook.SaveAs Filename:= _
        "C:\Temp\Example.xlsx", FileFormat:= _
        xlOpenXMLWorkbook

End Sub

The key is to rewrite this query so that it can be used as a subquery.

SELECT firstname, 
   lastname, 
   list.address 
FROM list
   INNER JOIN (SELECT address
               FROM   list
               GROUP  BY address
               HAVING COUNT(id) > 1) dup
           ON list.address = dup.address;

The JUnit way is to do this at run-time is org.junit.Assume.

 @Before
 public void beforeMethod() {
     org.junit.Assume.assumeTrue(someCondition());
     // rest of setup.
 }

You can do it in a @Before method or in the test itself, but not in an @After method. If you do it in the test itself, your @Before method will get run. You can also do it within @BeforeClass to prevent class initialization.

An assumption failure causes the test to be ignored.

Edit: To compare with the @RunIf annotation from junit-ext, their sample code would look like this:

@Test
public void calculateTotalSalary() {
    assumeThat(Database.connect(), is(notNull()));
    //test code below.
}

Not to mention that it is much easier to capture and use the connection from the Database.connect() method this way.

clip-path: circle(100px at center);

This will actually make clickable only circle, while border-radius still makes a square, but looks as circle.

Your class's constructor method should be called __construct(), not __constructor():

public function __construct(EntityManager $entityManager)
{
    $this->em = $entityManager;
}

I just solved this issue myself. You were on the right track.

@media (min-width: 1200px) {
    .container{
        max-width: 970px;
    }
}

Here we say: On viewports 1200px or larger - set container max-width to 970px. This will overwrite the standard class that currently sets max-width to 1170px for that range.

NOTE: Make sure you include this AFTER the bootstrap.css stuff (everyone has made this little mistake in the past).

Hope this helps.. good luck!

Off the top of my head and not guaranteed to be correct: I believe the second will be faster in this case.

1. In the first, the correlated subquery will likely cause the subquery to be run for each row.
2. In the second example, the subquery should only run once, since not correlated.
3. In the second example, the IN will short-circuit as soon as it finds a match.

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

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

Example:

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

If it is a parameter in a function, you can validate it with ValidateNotNullOrEmpty as you can see in this example:

Function Test-Something
{
    Param(
        [Parameter(Mandatory=$true)]
        [ValidateNotNullOrEmpty()]
        [string]$UserName
    )

    #stuff todo
}

i fixed my problem by this code on linux file system

if (!file.exists())
    Files.createFile(file.toPath());

A string is one string, a string[] is a string array. It means it's a variable with multiple strings in it.

Although you can convert a string to a string[] (create a string array with one element in it), it's probably a sign that you're trying to do something which you shouldn't do.

If you are wondering where you can download the shared library (although this will not work on your client's devices unless you include the dll) here is the link: https://de.osdn.net/projects/mingw/downloads/72215/libgcc-9.2.0-1-mingw32-dll-1.tar.xz/

I've found out a nice workaround to IP blocking when scraping sites. It lets you run a Scraper indefinitely by running it from Google App Engine and redeploying it automatically when you get a 429.

For reference using the [EnableCors()] approach will not work if you intercept the Message Pipeline using a DelegatingHandler. In my case was checking for an Authorization header in the request and handling it accordingly before the routing was even invoked, which meant my request was getting processed earlier in the pipeline so the [EnableCors()] had no effect.

In the end found an example CrossDomainHandler class (credit to shaunxu for the Gist) which handles the CORS for me in the pipeline and to use it is as simple as adding another message handler to the pipeline.

public class CrossDomainHandler : DelegatingHandler
    {
        const string Origin = "Origin";
        const string AccessControlRequestMethod = "Access-Control-Request-Method";
        const string AccessControlRequestHeaders = "Access-Control-Request-Headers";
        const string AccessControlAllowOrigin = "Access-Control-Allow-Origin";
        const string AccessControlAllowMethods = "Access-Control-Allow-Methods";
        const string AccessControlAllowHeaders = "Access-Control-Allow-Headers";

        protected override Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, CancellationToken cancellationToken)
        {
            bool isCorsRequest = request.Headers.Contains(Origin);
            bool isPreflightRequest = request.Method == HttpMethod.Options;
            if (isCorsRequest)
            {
                if (isPreflightRequest)
                {
                    return Task.Factory.StartNew(() =>
                    {
                        HttpResponseMessage response = new HttpResponseMessage(HttpStatusCode.OK);
                        response.Headers.Add(AccessControlAllowOrigin, request.Headers.GetValues(Origin).First());

                        string accessControlRequestMethod = request.Headers.GetValues(AccessControlRequestMethod).FirstOrDefault();
                        if (accessControlRequestMethod != null)
                        {
                            response.Headers.Add(AccessControlAllowMethods, accessControlRequestMethod);
                        }

                        string requestedHeaders = string.Join(", ", request.Headers.GetValues(AccessControlRequestHeaders));
                        if (!string.IsNullOrEmpty(requestedHeaders))
                        {
                            response.Headers.Add(AccessControlAllowHeaders, requestedHeaders);
                        }

                        return response;
                    }, cancellationToken);
                }
                else
                {
                    return base.SendAsync(request, cancellationToken).ContinueWith(t =>
                    {
                        HttpResponseMessage resp = t.Result;
                        resp.Headers.Add(AccessControlAllowOrigin, request.Headers.GetValues(Origin).First());
                        return resp;
                    });
                }
            }
            else
            {
                return base.SendAsync(request, cancellationToken);
            }
        }
    }

To use it add it to the list of registered message handlers

config.MessageHandlers.Add(new CrossDomainHandler());

Any preflight requests by the Browser are handled and passed on, meaning I didn't need to implement an [HttpOptions] IHttpActionResult method on the Controller.

The Chrome CSS property -webkit-print-color-adjust: exact; works appropriately.

However, making sure you have the correct CSS for printing can often be tricky. Several things can be done to avoid the difficulties you are having. First, separate all your print CSS from your screen CSS. This is done via the @media print and @media screen.

Often times just setting up some extra @media print CSS is not enough because you still have all your other CSS included when printing as well. In these cases you just need to be aware of CSS specificity as the print rules don't automatically win against non-print CSS rules.

In your case, the -webkit-print-color-adjust: exact is working. However, your background-color and color definitions are being beaten out by other CSS with higher specificity.

While I do not endorse using !important in nearly any circumstance, the following definitions work properly and expose the problem:

@media print {
    tr.vendorListHeading {
        background-color: #1a4567 !important;
        -webkit-print-color-adjust: exact; 
    }
}

@media print {
    .vendorListHeading th {
        color: white !important;
    }
}

Here is the fiddle (and embedded for ease of print previewing).

You have a class of the same name declared more than once. Maybe via multiple includes. When including other files you need to use something like

include_once "something.php";

to prevent multiple inclusions. It's very easy for this to happen, though not always obvious, since you could have a long chain of files being included by one another.

best way to use:

typeof(T).Name

Png files can handle transparency. So you could use this question Save plot to image file instead of displaying it using Matplotlib so as to save you graph as a png file.

And if you want to turn all white pixel transparent, there's this other question : Using PIL to make all white pixels transparent?

If you want to turn an entire area to transparent, then there's this question: And then use the PIL library like in this question Python PIL: how to make area transparent in PNG? so as to make your graph transparent.

Basically, 1 is not a valid index of y. If the visitor is comming from his own code he should check if his y contains the index which he tries to access (in this case the index is 1).

Download Notepad++ (notepad-plus-plus.org) it opens nearly any file format and recognizes breaks, comments and does all the same color coding as the original language formatting.

function clean($data){
    $data = rawurldecode($data);
    return filter_var($data, FILTER_SANITIZE_SPEC_CHARS);
}

Just for the sake of keeping the information up-to-date, with at least JIRA 7.3.0 (maybe older as well) you can explicitly specify the date in multiple formats:

• 'yyyy/MM/dd HH:mm';
• 'yyyy-MM-dd HH:mm';
• 'yyyy/MM/dd';
• 'yyyy-MM-dd';
• period format, e.g. '-5d', '4w 2d'.

Example:

updatedDate > '2018/06/09 0:00' and updatedDate < '2018/06/10 15:00'

outgoing url in mvc generated based on the current routing schema.

because your Information action method require id parameter, and your route collection has id of your current requested url(/Admin/Information/5), id parameter automatically gotten from existing route collection values.

to solve this problem you should use UrlParameter.Optional:

 <a href="@Url.Action("Information", "Admin", new { id = UrlParameter.Optional })">Add an Admin</a>

If you're using ES6, you can do this:

if (['afshin', 'saeed', 'larry'].includes(varName)) {
   alert('Hey');
} else {
   alert('Default case');
}

Or for earlier versions of JavaScript, you can do this:

if (['afshin', 'saeed', 'larry'].indexOf(varName) !== -1) {
   alert('Hey');
} else {
   alert('Default case');
}

Note that this won't work in older IE browsers, but you could patch things up fairly easily. See the question determine if string is in list in javascript for more information.

Given that your strings are all fixed-length (presumably at compile-time?), you can do the following:

char (*orderedIds)[ID_LEN+1]
    = malloc(variableNumberOfElements * sizeof(*orderedIds));

// Clear-up
free(orderedIds);

A more cumbersome, but more general, solution, is to assign an array of pointers, and psuedo-initialising them to point at elements of a raw backing array:

char *raw = malloc(variableNumberOfElements * (ID_LEN + 1));
char **orderedIds = malloc(sizeof(*orderedIds) * variableNumberOfElements);

// Set each pointer to the start of its corresponding section of the raw buffer.
for (i = 0; i < variableNumberOfElements; i++)
{
    orderedIds[i] = &raw[i * (ID_LEN+1)];
}

...

// Clear-up pointer array
free(orderedIds);
// Clear-up raw array
free(raw);
