JetBrains is going to add a decompiler to its ReSharper, and release a stand-alone decompiler too.

The good news is that we’re preparing a standalone binary-as-a-source application, i.e. a decompiler + assembly browser to explore whatever .NET compiled code is legal to explore. We don’t have any specific date for release, but it’s going to be released this year, and it’s going to be free of charge. And by saying “free”, we actually mean “free”.

Here is more information.

UPDATE: JetBrains has now released the product called dotPeek and it can be found here.

There's an article over on MSDN that has a sample application for zipping and unzipping files and folders purely in C#. I've been using some of the classes in that successfully for a long time. The code is released under the Microsoft Permissive License, if you need to know that sort of thing.

EDIT: Thanks to Cheeso for pointing out that I'm a bit behind the times. The MSDN example I pointed to is in fact using DotNetZip and is really very fully-featured these days. Based on my experience of a previous version of this I'd happily recommend it.

SharpZipLib is also quite a mature library and is highly rated by people, and is available under the GPL license. It really depends on your zipping needs and how you view the license terms for each of them.

Hi There are two possible reasons.

1. We have un-managed code and we are calling it from managed code. that is preventing to run this code. try running these commands and restart your pc

   cmd: netsh winsock reset

open cmd.exe and run command "netsh winsock reset catalog"

2. Anti-virus is considering un-managed code as harmful and restricting to run this code disable anti-virus and then check

Change <?php echo $proxy ?> to ' . $proxy . '.

You use <?php when you're outputting HTML by leaving PHP mode with ?>. When you using echo, you have to use concatenation, or wrap your string in double quotes and use interpolation.

function deleteFromArray(array, indexToDelete){
  var remain = new Array();
  for(var i in array){
    if(array[i] == indexToDelete){
      continue;
    }
    remain.push(array[i]);
  }
  return remain;
}

myArray = ['a', 'b', 'c', 'd'];
deleteFromArray(myArray , 0);

// result : myArray = ['b', 'c', 'd'];

Caution:

np.array_split doesn't work with numpy-1.9.0. I checked out: It works with 1.8.1.

Somewhere you have to keep track of what button had been pressed. When things happen, you need to store something in a variable so you can recall the information or it's gone forever.

When someone pressed one of the operator buttons, don't just let them type in another value. Save the operator symbol, then let them type in another value. You could literally just have a String operator that gets the text of the operator button pressed. Then, when the equals button is pressed, you have to check to see which operator you stored. You could do this with an if/else if/else chain.

So, in your symbol's button press event, store the symbol text in a variable, then, in the = button press event, check to see which symbol is in the variable and act accordingly.

Alternatively, if you feel comfortable enough with enums (looks like you're just starting, so if you're not to that point yet, ignore this), you could have an enumeration of symbols that lets you check symbols easily with a switch.

UIView's pointInside:withEvent: could be a good solution. Will return a boolean value indicating wether or not the given CGPoint is in the UIView instance you are using. Example:

UIView *aView = [UIView alloc]initWithFrame:CGRectMake(0,0,100,100);
CGPoint aPoint = CGPointMake(5,5);
BOOL isPointInsideView = [aView pointInside:aPoint withEvent:nil];

One more variation wrapped up nicely where setAttribute isn't needed.

There are 3 lines that wouldn't be needed if Wetfox could dry off.

var saveAs = function (filename, content) {
    if(filename === undefined) filename = "Unknown.txt";
    if(content === undefined) content = "Empty?!";
    let link = document.createElement('a');
    link.style.display = "none"; // because Firefox sux
    document.body.appendChild(link); // because Firefox sux
    link.href = "data:application/octet-stream," + encodeURIComponent(content);
    link.download = filename;
    link.click();
    document.body.removeChild(link); // because Firefox sux
};

Thanks for the help.

Here's my take at it. The assumption is, when the URL changes but there has no click within the document detected, it's a browser back (yes, or forward). A users click is reset after 2 seconds to make this work on pages that load content via Ajax:

(function(window, $) {
  var anyClick, consoleLog, debug, delay;
  delay = function(sec, func) {
    return setTimeout(func, sec * 1000);
  };
  debug = true;
  anyClick = false;
  consoleLog = function(type, message) {
    if (debug) {
      return console[type](message);
    }
  };
  $(window.document).click(function() {
    anyClick = true;
    consoleLog("info", "clicked");
    return delay(2, function() {
      consoleLog("info", "reset click state");
      return anyClick = false;
    });
  });
  return window.addEventListener("popstate", function(e) {
    if (anyClick !== true) {
      consoleLog("info", "Back clicked");
      return window.dataLayer.push({
        event: 'analyticsEvent',
        eventCategory: 'test',
        eventAction: 'test'
      });
    }
  });
})(window, jQuery);

In Swift 3.0 :

var imageView : UIImageView
    imageView  = UIImageView(frame:CGRect(x:10, y:50, width:100, height:300));
    imageView.image = UIImage(named:"Test.jpeg")
    self.view.addSubview(imageView)

What do you want to search near that known place?

For example if you want to search a restaurant near a known place you can use the parameters "q=" and "near=" and construct this URL: maps.google.com/?q=restaurant&near=47.154719,27.60551

For a list of complete parameters you can see this: https://web.archive.org/web/20070708030513/http://mapki.com/wiki/Google_Map_Parameters

Depending on what is the format you want your information in you can add at the end of the url the parameter output like this: maps.google.com/?q=restaurant&near=47.154719,27.60551&output=kml

For more types of output format you can read chapter 2 of this: http://csie-tw.blogspot.de/2009/06/android-driving-direction-route-path.html

SELECT 
    u . *
FROM
    room u
        JOIN
    facilities_r fu ON fu.id_uc = u.id_uc
        AND (fu.id_fu = '4' OR fu.id_fu = '3')
WHERE
    1 and vizibility = '1'
GROUP BY id_uc
ORDER BY u_premium desc , id_uc desc

You must use OR here, not AND.

Since id_fu cannot be equal to 4 and 3, both at once.

Using the request module solved the issue.

// Include the request library for Node.js   
var request = require('request');
//  Basic Authentication credentials   
var username = "vinod"; 
var password = "12345";
var authenticationHeader = "Basic " + new Buffer(username + ":" + password).toString("base64");
request(   
{
url : "https://133-70-97-54-43.sample.com/feedSample/Query_Status_View/Query_Status/Output1?STATUS=Joined%20school",
headers : { "Authorization" : authenticationHeader }  
},
 function (error, response, body) {
 console.log(body); }  );         

As mentionned in comments: you need a way to send your static files to the client. This can be achieved with a reverse proxy like Nginx, or simply using express.static().

Put all your "static" (css, js, images) files in a folder dedicated to it, different from where you put your "views" (html files in your case). I'll call it static for the example. Once it's done, add this line in your server code:

app.use("/static", express.static('./static/'));

This will effectively serve every file in your "static" folder via the /static route.

Querying your index.js file in the client thus becomes:

<script src="static/index.js"></script>

Another scenario, again for the benefit of people searching.

For me this error occurred during the Dispose() method which masked a previous error unrelated to encryption.

Once the other component was fixed, this exception went away.

Right click the figure, select Insert Caption, Select Numbering, check box next to 'Include chapter number', select OK, Select OK again, then you figure identifier should be updated.

You should be careful to leave a space between the sign of '[' and double quotes where the variable contains this:

if [ "$s1" == "$s2" ]; then
#   ^     ^  ^     ^
   echo match
fi

The ^s show the blank spaces you need to leave.

Here is an interesting library: https://github.com/Flipboard/FLAnimatedImage

I tested the demo example and it's working great. It's a child of UIImageView. So I think you can use it in your Storyboard directly as well.

Cheers

1. Style parent element: style="display:flex; flex-direction:column; flex:1;"

2. Style the element you want to stay at bottom: style="margin-top: auto;"

3. Done! Wow. That was easy.

Example:

<section style="display:flex; flex-wrap:wrap;"> // For demo, not necessary
    <div style="display:flex; flex-direction:column; flex:1;"> // Parent element
        <button style="margin-top: auto;"> I </button> // Target element
    </div>

    ... 5 more identical divs, for demo ...

</section>

Demo: https://codepen.io/ferittuncer/pen/YzygpWX

SELECT
    OBJECT_NAME(PARENT_OBJECT_ID) AS PARENT_TABLE,
    OBJECT_NAME(OBJECT_ID) TRIGGER_TABLE,
    *
FROM
SYS.OBJECTS

Json stands for JavaScript Object Notation really all json is are javascript objects so your array is in json form already. To write it out in a div you could do a bunch of things one of the easiest I think would be:

 objectDiv.innerHTML = filter;

where objectDiv is the div you want selected from the DOM using jquery. If you wanted to list parts of the array out you could access them since it is a javascript object like so:

 objectDiv.innerHTML = filter.dvals.valueToDisplay; //brand or count depending.

edit: anything you want to be a string but is not currently (which is rare javascript treats almost everything as a string) just use the toString() function built in. so line above if you needed it would be filter.dvals.valueToDisplay.toString();

second edit to clarify: this answer is in response to the OP's comments and not completely to his original question.

I've used the open source control at http://dropdowncheckboxes.codeplex.com/ and been very happy with it. My addition was to allow a list of checked files to use just file names instead of full paths if the 'selected' caption gets too long. My addition is called instead of UpdateSelection in your postback handler:

// Update the caption assuming that the items are files<br/> 
// If the caption is too long, eliminate paths from file names<br/> 
public void UpdateSelectionFiles(int maxChars) {
  StringBuilder full = new StringBuilder(); 
  StringBuilder shorter = new StringBuilder();
  foreach (ListItem item in Items) { 
    if (item.Selected) { 
      full.AppendFormat("{0}; ", item.Text);
      shorter.AppendFormat("{0}; ", new FileInfo(item.Text).Name);
    } 
  } 
  if (full.Length == 0) Texts.SelectBoxCaption = "Select...";
  else if (full.Length <= maxChars) Texts.SelectBoxCaption = full.ToString(); 
  else Texts.SelectBoxCaption = shorter.ToString();
} 

First you have an architectural issue with your classes. You moved the property deck inside your class Card. But of couse it is a property of the card deck and thus has to be inside class DeckOfCards. The initialization loop should then not be in the constructor of Card but of your deck class. Moreover, the deck is an array of int at the moment but should be an array of Cards.

Second, inside method Deal you should refer to suits as Card.suits and make this member static final. Same for ranks.

And last, please stick to naming conventions. Method names are always starting with a lower case letter, i.e. shuffle instead of Shuffle.

I was looking for something like this and after some tries and falls i create my own makefile, I know that's not the "idiomatic way" but it's a begining to understand make and this works for me, maybe you could try in your project.

Our team use Visual Paradigm to generate ER diagram from database in many of our projects. While we mainly work on MS SQL and Oracle, as I know they also support some other DBMS like PostgreSQL, MySQL, Sybase, DB2 and SQLite.

Steps:

1. Select Tools > DB > Reverse Database... from the toolbar of Visual Paradigm
2. Keep the settings as is and click Next Select PostgreSQL as driver and provide the driver file there. You can simply click on the download link there to get the driver.
3. Enter the hostname, database name, user and password, and then click Next
4. They will then study your database and lists out the tables in it.
5. Select the table to form an ERD and continue, and that's it. An ERD will be generated with the tables you selected presented.

BTW they also support generating and updating database schema from ERD.

Hope this helps. :-)

Since I was not too happy with the output of other (non-tree) answers (see my comment at Hassou's answer), I tried to mimic trees output a bit more.

It's similar to the answer of Robert but the horizontal lines do not all start at the beginning, but where there are supposed to start. Had to use perl though, but in my case, on the system where I don't have tree, perl is available.

ls -aR | grep ":$" | perl -pe 's/:$//;s/[^-][^\/]*\//    /g;s/^    (\S)/+-- \1/;s/(^    |    (?= ))/¦   /g;s/    (\S)/+-- \1/'

Output (shortened):

.
+-- fd
+-- net
¦   +-- dev_snmp6
¦   +-- nfsfs
¦   +-- rpc
¦   ¦   +-- auth.unix.ip
¦   +-- stat
¦   +-- vlan
+-- ns
+-- task

¦   ¦   ¦   ¦   +-- auth.unix.gid
¦   ¦   ¦   ¦   +-- auth.unix.ip
¦   ¦   ¦   +-- stat
¦   ¦   ¦   +-- vlan
¦   ¦   +-- ns

Suggestions to avoid the superfluous vertical lines are welcome :-)

I still like Ben's solution in the comment of Hassou's answer very much, without the (not perfectly correct) lines it's much cleaner. For my use case I additionally removed the global indentation and added the option to also ls hidden files, like so:

ls -aR | grep ":$" | sed -e 's/:$//' -e 's/[^-][^\/]*\//  /g'

Output (shortened even more):

.
  fd
  net
    dev_snmp6
    nfsfs
    rpc
      auth.unix.ip
    stat
    vlan

I realize you've already accepted an answer for this, but I wrote this short howto article to install mongodb into the c:\wamp directory and run it as a service. Here is the gist of it.

Create these directories

mkdir c:\wamp\bin\mongodb\mongodb-win32...2.x.x\data
mkdir c:\wamp\bin\mongodb\mongodb-win32...2.x.x\data\db
mkdir c:\wamp\bin\mongodb\mongodb-win32...2.x.x\logs
mkdir c:\wamp\bin\mongodb\mongodb-win32...2.x.x\conf

Download and extract win32 binaries into c:\wamp directory along side mysql, apache.

mongodb download page

Create a mongo.conf file

c:\wamp\bin\mongodb\mongodb-win32…2.x.x\conf\mongodb.conf

# mongodb.conf

# data lives here
dbpath=C:\wamp\bin\mongodb\mongodb-win32...2.x.x\data\db

# where to log
logpath=C:\wamp\bin\mongodb\mongodb-win32...2.x.x\logs\mongodb.log
logappend=true

# only run on localhost for development
bind_ip = 127.0.0.1                                                             

port = 27017
rest = true

Install as a service

mongod.exe --install --config c:\wamp\bin\mongodb\mongodb-win32...2.x.x\conf\mongodb.conf --logpath c:\wamp\bin\mongodb\mongodb-win32...2.x.x\logs\mongodb.log

Set service to automatic and start it using services.msc

Add path to mongo.exe to your path

Installing MongoDB on Windows the WAMP way

This can be done by creating a .pgpass file in the home directory of the (Linux) User. .pgpass file format:

<databaseip>:<port>:<databasename>:<dbusername>:<password>

You can also use wild card * in place of details.

Say I wanted to run tmp.sql without prompting for a password.

With the following code you can in *.sh file

echo "192.168.1.1:*:*:postgres:postgrespwd" > $HOME/.pgpass
echo "` chmod 0600 $HOME/.pgpass `"

echo " ` psql -h 192.168.1.1 -p 5432  -U postgres  postgres  -f tmp.sql `        

This is one of the points in C that can be confusing at first, but the C standard only specifies a minimum range for integer types that is guaranteed to be supported. int is guaranteed to be able to hold -32767 to 32767, which requires 16 bits. In that case, int, is 2 bytes. However, implementations are free to go beyond that minimum, as you will see that many modern compilers make int 32-bit (which also means 4 bytes pretty ubiquitously).

The reason your book says 2 bytes is most probably because it's old. At one time, this was the norm. In general, you should always use the sizeof operator if you need to find out how many bytes it is on the platform you're using.

To address this, C99 added new types where you can explicitly ask for a certain sized integer, for example int16_t or int32_t. Prior to that, there was no universal way to get an integer of a specific width (although most platforms provided similar types on a per-platform basis).

set the height to 200

Set the Font to a large variant (150+ px). As already mentioned, control the width using columns, and use a layout manager (or constraint) that will respect the preferred width & height.

It's by value according to the PHP Documentation.

By default, function arguments are passed by value (so that if the value of the argument within the function is changed, it does not get changed outside of the function). To allow a function to modify its arguments, they must be passed by reference.

To have an argument to a function always passed by reference, prepend an ampersand (&) to the argument name in the function definition.

<?php
function add_some_extra(&$string)
{
    $string .= 'and something extra.';
}

$str = 'This is a string, ';
add_some_extra($str);
echo $str;    // outputs 'This is a string, and something extra.'
?>

For me it worked like I had images in icons folder under src and I wrote below code.

new ImageIcon(getClass().getResource("/icons/rsz_measurment_01.png"));

I am assuming that you know how to iterate over elements in some list:

for el in my_list:
    # do something

Now sometimes not only you need to iterate over the elements, but also you need the index for each iteration. One way to do it is:

i = 0
for el in my_list:
    # do somethings, and use value of "i" somehow
    i += 1

However, a nicer way is to user the function "enumerate". What enumerate does is that it receives a list, and it returns a list-like object (an iterable that you can iterate over) but each element of this new list itself contains 2 elements: the index and the value from that original input list: So if you have

arr = ['a', 'b', 'c']

Then the command enumerate(arr) returns something like:

[(0,'a'), (1,'b'), (2,'c')]

Now If you iterate over a list (or an iterable) where each element itself has 2 sub-elements, you can capture both of those sub-elements in the for loop like below:

for index, value in enumerate(arr):
    print(index,value)

which would print out the sub-elements of the output of enumerate.

And in general you can basically "unpack" multiple items from list into multiple variables like below:

idx,value = (2,'c')
print(idx)
print(value)

which would print

2
c

This is the kind of assignment happening in each iteration of that loop with enumerate(arr) as iterable.

When you are dealing with objects, you want to ignore simple id's as much as convenient.

If you change the click line to this, I think you will be well on your way:

<li class="tutorial_title {{tutorial.active}}" ng-click="loadFromMenu(tutorial)" ng-repeat="tutorial in section.tutorials">

Also, I think you may need to change

class="tutorial_title {{tutorial.active}}"

to something like

ng-class="tutorial_title {{tutorial.active}}"

See http://docs.angularjs.org/misc/faq and look for ng-class.

What you may actually want to use is an Iterable that can return a fresh Iterator multiple times by calling iterator().

//A function that needs to iterate multiple times can be given one Iterable:
public void func(Iterable<Type> ible) {
    Iterator<Type> it = ible.iterator(); //Gets an iterator
    while (it.hasNext()) {
        it.next();
    }
    it = ible.iterator(); //Gets a NEW iterator, also from the beginning
    while (it.hasNext()) {
        it.next();
    }
}

You must define what the iterator() method does just once beforehand:

void main() {
    LinkedList<String> list; //This could be any type of object that has an iterator
    //Define an Iterable that knows how to retrieve a fresh iterator
    Iterable<Type> ible = new Iterable<Type>() {
        @Override
        public Iterator<Type> iterator() {
            return list.listIterator(); //Define how to get a fresh iterator from any object
        }
    };
    //Now with a single instance of an Iterable,
    func(ible); //you can iterate through it multiple times.
}

sorry to use up some space on just a reiteration of the previously given answer - but this is something I always end up in trouble with.

Let's say I've updated the local files to the latest revision, which is 854. Then, I'd want to get an older revision - the version of the file from few revision earlier, say revision 851.

Copy would work:

svn copy -r 851 svn+ssh://<repository URL>/l3toks.dtx ./l3toks.dtx

.. however, I can't be bothered grepping for the repo URL :)

Update seemingly might work:

svn up -r 851 ./l3toks.dtx

... however, it also marks the local copy as "freshly checked out", or rather "same as online revision" (i.e. in Tortoise/RabbitVCS you get a green OK checkmark) - which means you cannot do svn ci -m "rolled back to r 851": simply because the local subversion executable won't notice any local changes, and won't be bothered to upload anything to the online repository.

And, as already answered, reverse merge works - but in this case, one shouldn't rely on shortcut syntax; but specifically state:

svn merge -r HEAD:851 l3toks.dtx
--- Reverse-merging r854 through r852 into 'l3toks.dtx':
U    l3toks.dtx

I must admit - I would never understand the sentence "Reverse-merging r854 through r852 into file" to mean "Just got r851 of your file, and overwritten whatever you had previously locally - and it is marked as different from latest online revision, so you can check it back in online as a new 'rollback' revision", but I guess (and hope :) ) that is what it does :)

After this, one can use svn diff for a quick make-sure if we got the right revision back locally; and also, the file will be marked with a red exclamation mark in Tortoise/RabbitVCS (that is, different from latest committed version), and so svn ci -m "rolled back to r 851" can run this time.

Also, note that if you, finally, change your mind after reverse merging (i.e. you anyways want to keep working on the latest, HEAD revision, here 854 - after you have rolled back to 851 locally, but haven't yet committed the rollback), you shouldn't use svn up, because it will simply say that it is already "At revision 854"; use instead svn revert --recursive . or similar...

Cheers!

Ref: How to Roll Back Changes using Subversion - Jacob Wright – Flex, AIR, PHP, etc.

EDIT: ... and apparently, the exactly same effect as svn merge -r HEAD:851 l3toks.dtx, can be achieved with:

svn export -r 851 l3toks.dtx
A    l3toks.dtx
Export complete.

On Debian the best way to do it would be

sudo apt-get install python-pip

It'd be better to use List<T>.RemoveAll to accomplish this.

authorsList.RemoveAll((x) => x.firstname == "Bob");

You can try this method that is developed by Chucai Yi and Yingli Tian.

They also share a software (which is based on Opencv-1.0 and it should run under Windows platform.) that you can use (though no source code available). It will generate all the text bounding boxes (shown in color shadows) in the image. By applying to your sample images, you will get the following results:

Note: to make the result more robust, you can further merge adjacent boxes together.

Update: If your ultimate goal is to recognize the texts in the image, you can further check out gttext, which is an OCR free software and Ground Truthing tool for Color Images with Text. Source code is also available.

With this, you can get recognized texts like:

Here are few pointers/suggestions for investigation

1. I see that every time you vote, you call vote method which creates a fresh HTTP connection.
2. This might be a problem. I would suggest to use a single HttpClient instance to post to the server. This way it wont create too many connections from the client side.
3. At the end of everything, HttpClient needs to be shut and hence call httpclient.getConnectionManager().shutdown(); to release the resources used by the connections.

You can invoke reflections and also, set order of sequence for getter for values through annotations

The advantage of lists appears if you need to insert items in the middle and don't want to start resizing the array and shifting things around.

You're correct in that this is typically not the case. I've had a few very specific cases like that, but not too many.

In addition to the above mentioned answers: I wanted to start a job with a simple parameter passed to a second pipeline and found the answer on http://web.archive.org/web/20160209062101/https://dzone.com/refcardz/continuous-delivery-with-jenkins-workflow

So i used:

stage ('Starting ART job') {
    build job: 'RunArtInTest', parameters: [[$class: 'StringParameterValue', name: 'systemname', value: systemname]]
}

You could run it without the -jar command line argument if you happen to know the name of the main class you wish to run:

java -classpath .;myjar.jar;lib/referenced-class.jar my.package.MainClass

If perchance you are using linux, you should use ":" instead of ";" in the classpath.

I suppose you want to get the content generated by PHP, if so use:

$Vdata = file_get_contents('http://YOUR_HOST/YOUR/FILE.php');

Otherwise if you want to get the source code of the PHP file, it's the same as a .txt file:

$Vdata = file_get_contents('path/to/YOUR/FILE.php');

  $('#subscribeForm').validate( {
      rules: {
          list: {
              required: true,
              minlength: 1
          }
       }
   });

I think this will make sure at least one is checked.

I have a proper solution of this problem, lets try and understand the root cause of this issue. This issue comes when remote servers ssl cannot be verified using root certificates in your system's certificate store or remote ssl is not installed along with chain certificates. If you have a linux system with root ssh access, then in this case you can try updating your certificate store with below command:

update-ca-certificates

If still, it doesn't work then you need to add root and interim certificate of remote server in your cert store. You can download root and intermediate certs and add them in /usr/local/share/ca-certificates directory and then run command update-ca-certificates. This should do the trick. Similarly for windows you can search how to add root and intermediate cert.

The other way you can solve this problem is by asking remote server team to add ssl certificate as a bundle of domain root cert, intermediate cert and root cert.

How floats work

When floating elements exist on the page, non-floating elements wrap around the floating elements, similar to how text goes around a picture in a newspaper. From a document perspective (the original purpose of HTML), this is how floats work.

float vs display:inline

Before the invention of display:inline-block, websites use float to set elements beside each other. float is preferred over display:inline since with the latter, you can't set the element's dimensions (width and height) as well as vertical paddings (top and bottom) - which floated elements can do since they're treated as block elements.

Float problems

The main problem is that we're using float against its intended purpose.

Another is that while float allows side-by-side block-level elements, floats do not impart shape to its container. It's like position:absolute, where the element is "taken out of the layout". For instance, when an empty container contains a floating 100px x 100px <div>, the <div> will not impart 100px in height to the container.

Unlike position:absolute, it affects the content that surrounds it. Content after the floated element will "wrap" around the element. It starts by rendering beside it and then below it, like how newspaper text would flow around an image.

Clearfix to the rescue

What clearfix does is to force content after the floats or the container containing the floats to render below it. There are a lot of versions for clear-fix, but it got its name from the version that's commonly being used - the one that uses the CSS property clear.

Examples

Here are several ways to do clearfix , depending on the browser and use case. One only needs to know how to use the clear property in CSS and how floats render in each browser in order to achieve a perfect cross-browser clear-fix.

What you have

Your provided style is a form of clearfix with backwards compatibility. I found an article about this clearfix. It turns out, it's an OLD clearfix - still catering the old browsers. There is a newer, cleaner version of it in the article also. Here's the breakdown:

• The first clearfix you have appends an invisible pseudo-element, which is styled clear:both, between the target element and the next element. This forces the pseudo-element to render below the target, and the next element below the pseudo-element.

• The second one appends the style display:inline-block which is not supported by earlier browsers. inline-block is like inline but gives you some properties that block elements, like width, height as well as vertical padding. This was targeted for IE-MAC.

• This was the reapplication of display:block due to IE-MAC rule above. This rule was "hidden" from IE-MAC.

All in all, these 3 rules keep the .clearfix working cross-browser, with old browsers in mind.

I recently had this same problem. Unfortunately, NotifyIcon is only a Windows.Forms control at the moment, if you want to use it you are going to have to include that part of the framework. I guess that depends how much of a WPF purist you are.

If you want a quick and easy way of getting started check out this WPF NotifyIcon control on the Code Project which does not rely on the WinForms NotifyIcon at all. A more recent version seems to be available on the author's website and as a NuGet package. This seems like the best and cleanest way to me so far.

Simply used this custom dialog class which field you not needed to leave it or make it null so this customization you got easily.

import 'package:flutter/material.dart';

class CustomAlertDialog extends StatelessWidget {
  final Color bgColor;
  final String title;
  final String message;
  final String positiveBtnText;
  final String negativeBtnText;
  final Function onPostivePressed;
  final Function onNegativePressed;
  final double circularBorderRadius;

  CustomAlertDialog({
    this.title,
    this.message,
    this.circularBorderRadius = 15.0,
    this.bgColor = Colors.white,
    this.positiveBtnText,
    this.negativeBtnText,
    this.onPostivePressed,
    this.onNegativePressed,
  })  : assert(bgColor != null),
        assert(circularBorderRadius != null);

  @override
  Widget build(BuildContext context) {
    return AlertDialog(
      title: title != null ? Text(title) : null,
      content: message != null ? Text(message) : null,
      backgroundColor: bgColor,
      shape: RoundedRectangleBorder(
          borderRadius: BorderRadius.circular(circularBorderRadius)),
      actions: <Widget>[
        negativeBtnText != null
            ? FlatButton(
                child: Text(negativeBtnText),
                textColor: Theme.of(context).accentColor,
                onPressed: () {
                  Navigator.of(context).pop();
                  if (onNegativePressed != null) {
                    onNegativePressed();
                  }
                },
              )
            : null,
        positiveBtnText != null
            ? FlatButton(
                child: Text(positiveBtnText),
                textColor: Theme.of(context).accentColor,
                onPressed: () {
                  if (onPostivePressed != null) {
                    onPostivePressed();
                  }
                },
              )
            : null,
      ],
    );
  }
}

Usage:

var dialog = CustomAlertDialog(
  title: "Logout",
  message: "Are you sure, do you want to logout?",
  onPostivePressed: () {},
  positiveBtnText: 'Yes',
  negativeBtnText: 'No');
showDialog(
  context: context,
  builder: (BuildContext context) => dialog);

Output:

No, it is not considered good practice. On the contrary, it is generally considered a bad idea.

http://www.gotw.ca/publications/mill22.htm goes into a lot more detail about why, but the problem is partly that the compiler is unable to enforce this, so it has to be checked at runtime, which is usually undesirable. And it is not well supported in any case. (MSVC ignores exception specifications, except throw(), which it interprets as a guarantee that no exception will be thrown.

If you need to convert the dictionary to binary, you need to convert it to a string (JSON) as described in the previous answer, then you can convert it to binary.

For example:

my_dict = {'key' : [1,2,3]}

import json
def dict_to_binary(the_dict):
    str = json.dumps(the_dict)
    binary = ' '.join(format(ord(letter), 'b') for letter in str)
    return binary


def binary_to_dict(the_binary):
    jsn = ''.join(chr(int(x, 2)) for x in the_binary.split())
    d = json.loads(jsn)  
    return d

bin = dict_to_binary(my_dict)
print bin

dct = binary_to_dict(bin)
print dct

will give the output

1111011 100010 1101011 100010 111010 100000 1011011 110001 101100 100000 110010 101100 100000 110011 1011101 1111101

{u'key': [1, 2, 3]}

Here is how my code looks like. It also shows an example of how to use query parameters using a dictionary. It works on using Python 3.6:

import cx_Oracle

CONN_INFO = {
    'host': 'xxx.xx.xxx.x',
    'port': 12345,
    'user': 'SOME_SCHEMA',
    'psw': 'SECRETE',
    'service': 'service.server.com'
}

CONN_STR = '{user}/{psw}@{host}:{port}/{service}'.format(**CONN_INFO)

QUERY = '''
    SELECT
        *
    FROM
        USER
    WHERE
        NAME = :name
'''


class DB:
    def __init__(self):
        self.conn = cx_Oracle.connect(CONN_STR)

    def query(self, query, params=None):
        cursor = self.conn.cursor()
        result = cursor.execute(query, params).fetchall()
        cursor.close()
        return result


db = DB()
result = db.query(QUERY, {'name': 'happy'})

So I did some more research into this and it turns out there isn't anything specific for this. I got excited when I found list.index(value), it returns the index of a specified item, but there isn't anything for getting the value at a specific index. So if you don't want to use the safe_list_get solution which I think is pretty good. Here are some 1 liner if statements that can get the job done for you depending on the scenario:

>>> x = [1, 2, 3]
>>> el = x[4] if len(x) > 4 else 'No'
>>> el
'No'

You can also use None instead of 'No', which makes more sense.:

>>> x = [1, 2, 3]
>>> i = 2
>>> el_i = x[i] if len(x) == i+1 else None

Also if you want to just get the first or last item in the list, this works

end_el = x[-1] if x else None

You can also make these into functions but I still liked the IndexError exception solution. I experimented with a dummied down version of the safe_list_get solution and made it a bit simpler (no default):

def list_get(l, i):
    try:
        return l[i]
    except IndexError:
        return None

Haven't benchmarked to see what is fastest.

It is amusing to return 418 I'm a teapot to requests that are obviously crafted or malicious and "can't happen", such as failing CSRF check or missing request properties.

2.3.2 418 I'm a teapot

Any attempt to brew coffee with a teapot should result in the error code "418 I'm a teapot". The resulting entity body MAY be short and stout.

To keep it reasonably serious, I restrict usage of funny error codes to RESTful endpoints that are not directly exposed to the user.

Because ( is special in regex, you should escape it \( when matching. However, depending on what language you are using, you can easily match ( with string methods like index() or other methods that enable you to find at what position the ( is in. Sometimes, there's no need to use regex.

instead of doing it like that, why not just make the flyout position:fixed, top:0; left:0; once your window has scrolled pass a certain height:

jQuery

  $(window).scroll(function(){
      if ($(this).scrollTop() > 135) {
          $('#task_flyout').addClass('fixed');
      } else {
          $('#task_flyout').removeClass('fixed');
      }
  });

css

.fixed {position:fixed; top:0; left:0;}

Example

Note: Simplest difference between sort() and sorted() is: sort() doesn't return any value while, sorted() returns an iterable list.

sort() doesn't return any value.

The sort() method just sorts the elements of a given list in a specific order - Ascending or Descending without returning any value.

The syntax of sort() method is:

list.sort(key=..., reverse=...)

Alternatively, you can also use Python's in-built function sorted() for the same purpose. sorted function return sorted list

 list=sorted(list, key=..., reverse=...)

TRUE and FALSE are keywords, and should not be quoted as strings:

INSERT INTO first VALUES (NULL, 'G22', TRUE);
INSERT INTO first VALUES (NULL, 'G23', FALSE);

By quoting them as strings, MySQL will then cast them to their integer equivalent (since booleans are really just a one-byte INT in MySQL), which translates into zero for any non-numeric string. Thus, you get 0 for both values in your table.

Non-numeric strings cast to zero:

mysql> SELECT CAST('TRUE' AS SIGNED), CAST('FALSE' AS SIGNED), CAST('12345' AS SIGNED);
+------------------------+-------------------------+-------------------------+
| CAST('TRUE' AS SIGNED) | CAST('FALSE' AS SIGNED) | CAST('12345' AS SIGNED) |
+------------------------+-------------------------+-------------------------+
|                      0 |                       0 |                   12345 |
+------------------------+-------------------------+-------------------------+

But the keywords return their corresponding INT representation:

mysql> SELECT TRUE, FALSE;
+------+-------+

Note also, that I have replaced your double-quotes with single quotes as are more standard SQL string enclosures. Finally, I have replaced your empty strings for id with NULL. The empty string may issue a warning.

You have to wrap the entire url statement in the bypassSecurityTrustStyle:

<div class="header" *ngIf="image" [style.background-image]="image"></div>

And have

this.image = this.sanitization.bypassSecurityTrustStyle(`url(${element.image})`);

Otherwise it is not seen as a valid style property

R.id.*, since ADT 14 are not more declared as final static int so you can not use in switch case construct. You could use if else clause instead.

    boolean x;
    for (x = false, 
        map.put("One", new Integer(1)), 
        map.put("Two", new Integer(2)),      
        map.put("Three", new Integer(3)); x;);

Ignoring the declaration of x (which is necessary to avoid an "unreachable statement" diagnostic), technically it's only one statement.

getUserRootFolder() {
  return process.env.HOME || process.env.HOMEPATH || process.env.USERPROFILE;
}

Try this

git config user.name

git config command stores and gives all the information.

git config -l

This commands gives you all the required info that you want.

You can change the information using

git config --global user.name "<Your-name>"

Similarly you can change many info shown to you using -l option.

SELECT CAST(GETDATE() AS DATE)

Returns the current date with the time part removed.

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

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

The display format in the question is independent of storage.

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

http://en.wikipedia.org/wiki/Printf#printf_format_placeholders

The article is about the class of printf functions, in several languages, from the 50s to this day.

Here is some code. without any error.

var image = canvas.toDataURL("image/png").replace("image/png", "image/octet-stream");  // here is the most important part because if you dont replace you will get a DOM 18 exception.


window.location.href=image; // it will save locally

This is an easy way for any format. Just change it to required format string

XMLGregorianCalendar gregFmt = DatatypeFactory.newInstance().newXMLGregorianCalendar(new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss").format(new Date()));
System.out.println(gregFmt);

I would suggest you have to use a Reader to convert your InputStream in.

BufferedReader streamReader = new BufferedReader(new InputStreamReader(in, "UTF-8")); 
StringBuilder responseStrBuilder = new StringBuilder();

String inputStr;
while ((inputStr = streamReader.readLine()) != null)
    responseStrBuilder.append(inputStr);
new JSONObject(responseStrBuilder.toString());

I tried in.toString() but it returns:

getClass().getName() + '@' + Integer.toHexString(hashCode())

(like documentation says it derives to toString from Object)

You could upload via $resource by assigning data to params attribute of resource actions like so:

$scope.uploadFile = function(files) {
    var fdata = new FormData();
    fdata.append("file", files[0]);

    $resource('api/post/:id', { id: "@id" }, {
        postWithFile: {
            method: "POST",
            data: fdata,
            transformRequest: angular.identity,
            headers: { 'Content-Type': undefined }
        }
    }).postWithFile(fdata).$promise.then(function(response){
         //successful 
    },function(error){
        //error
    });
};

Programmatic formatting solution:

The JSON.stringify method supported by many modern browsers (including IE8) can output a beautified JSON string:

JSON.stringify(jsObj, null, "\t"); // stringify with tabs inserted at each level
JSON.stringify(jsObj, null, 4);    // stringify with 4 spaces at each level

Demo: http://jsfiddle.net/AndyE/HZPVL/

This method is also included with json2.js, for supporting older browsers.

Manual formatting solution

If you don't need to do it programmatically, Try JSON Lint. Not only will it prettify your JSON, it will validate it at the same time.

Try this: parseInt(jQuery.offset().top, 10)

I run vscode from my command line by navigating to the folder with the code and running

Note: This example uses the draft version of the Flexible Box Layout Module. It has been superseded by the incompatible modern specification.

Center the child elements of a div box by using the box-align and box-pack properties together.

Example:

div
{
width:350px;
height:100px;
border:1px solid black;

/* Internet Explorer 10 */
display:-ms-flexbox;
-ms-flex-pack:center;
-ms-flex-align:center;

/* Firefox */
display:-moz-box;
-moz-box-pack:center;
-moz-box-align:center;

/* Safari, Opera, and Chrome */
display:-webkit-box;
-webkit-box-pack:center;
-webkit-box-align:center;

/* W3C */
display:box;
box-pack:center;
box-align:center;
}

git pull origin master will fetch all the changes from the remote's master branch and will merge it into your local.We generally don't use git pull origin/master.We can do the same thing by git merge origin/master.It will merge all the changes from "cached copy" of origin's master branch into your local branch.In my case git pull origin/master is throwing the error.

I have the same problem with a class. I tried composer dump-autoload and php artisan config:clear but it did not solve my problem.

Then I decided to read my code to find the problem and I found the problem. The problem in my case was a missing comma in my class. See my Model code:

{
    protected
    $fillable = ['agente_id', 'matter_id', 'amendment_id', 'tipo_id'];

    public
    $rules = [
        'agente_id' => 'required', // <= See the comma
        'tipo_id' => 'required'
    ];

    public
    $niceNames = [
        'agente_id' => 'Membro', // <= This comma is missing on my code
        'tipo_id' => 'Membro'
    ];
}

Any columns not included will be left as is.

I'm pretty sure this isn't a recommended practice anywhere in the sane world, but I like to line system includes up by filename length, sorted lexically within the same length. Like so:

#include <set>
#include <vector>
#include <algorithm>
#include <functional>

I think it's a good idea to include your own headers before other peoples, to avoid the shame of include-order dependency.

Make sure the scp command is available on both sides - both on the client and on the server.

If this is Fedora or Red Hat Enterprise Linux and clones (CentOS), make sure this package is installed:

    yum -y install openssh-clients

If you work with Debian or Ubuntu and clones, install this package:

    apt-get install openssh-client

Again, you need to do this both on the server and the client, otherwise you can encounter "weird" error messages on your client: scp: command not found or similar although you have it locally. This already confused thousands of people, I guess :)

I had the same problem while designing a template in Mailjet. Solution of the problem was minified CSS code inside <style> tags.

Pure jQuery.

$.ajax({
  type: "GET",
  url: "https://example.com/file",
  headers: {
    'Authorization': 'Bearer eyJraWQiFUDA.......TZxX1MGDGyg'
  },
  xhrFields: {
    responseType: 'blob'
  },
  success: function (blob) {
    var windowUrl = window.URL || window.webkitURL;
    var url = windowUrl.createObjectURL(blob);
    var anchor = document.createElement('a');
    anchor.href = url;
    anchor.download = 'filename.zip';
    anchor.click();
    anchor.parentNode.removeChild(anchor);
    windowUrl.revokeObjectURL(url);
  },
  error: function (error) {
    console.log(error);
  }
});

You may go with this way: ( a general example )

insert into QualityAssuranceDB.dbo.Customers (columnA, ColumnB)
Select columnA, columnB from DeveloperDB.dbo.Customers

Also if you need to generate the column names as well to put in insert clause, use:

    select (name + ',') as TableColumns from sys.columns 
where object_id = object_id('YourTableName')

Copy the result and paste into query window to represent your table column names and even this will exclude the identity column as well:

    select (name + ',') as TableColumns from sys.columns 
where object_id = object_id('YourTableName') and is_identity = 0

Remember the script to copy rows will work if the databases belongs to the same location.

You can Try This.

select * into <Destination_table> from <Servername>.<DatabaseName>.dbo.<sourceTable>

Server name is optional if both DB is in same server.

The answer is only valid if you have not changed the "Sketchbook Location" field in Preferences. So, first, you need to open the Arduino IDE and go to the menu

"File -> Preferences"

In the dialog, look at the field "Sketchbook Location" and open the corresponding folder. The "libraries" folder in inside.

Use a Page Viewer webpart and switch from Web Page to Folder. You can the specify the folder you want to display in the Link.

Use fileReader.readAsDataURL( fileObject ), this will encode it to base64, which you can safely upload to your server.

Format to send a WhatsApp message to a specific number (updated Nov 2018)

<a href="https://wa.me/whatsappphonenumber/?text=urlencodedtext"></a>

where

whatsappphonenumber is a full phone number in international format

urlencodedtext is the URL-encoded pre-filled message.

Example:

1. Create a link with a pre-filled message that will automatically appear in the text field of a chat, to be sent to a specific number

   Send I am interested in your car for sale to +001-(555)1234567

   https://wa.me/15551234567?text=I%20am%20interested%20in%20your%20car%20for%20sale

   Note :

   Use: https://wa.me/15551234567

   Don't use: https://wa.me/+001-(555)1234567

2. Create a link with just a pre-filled message that will automatically appear in the text field of a chat, number will be chosen by the user

   Send I am enquiring about the apartment listing

   https://wa.me/?text=I%20am%20enquiring%20about%20the%20apartment%20listing

   After clicking on the link, user will be shown a list of contacts they can send the pre-filled message to.

For more information, see https://www.whatsapp.com/faq/en/general/26000030

You can also do it with jQuery:

var options = ["1", "2", "3", "4", "5"];
$('#select').empty();
$.each(options, function(i, p) {
    $('#select').append($('<option></option>').val(p).html(p));
});

Using the AWS Management Console

• Go to "Volumes" and create a Snapshot of your instance's volume.
• Go to "Snapshots" and select "Create Image from Snapshot".
• Go to "AMIs" and select "Launch Instance" and choose your "Instance Type" etc.

Here is a modified version of Steven Harris' that is plain ES5 and returns an object keyed on the id rather than returning an array of nodes at both the top level and for the children.

unflattenToObject = function(array, parent) {
  var tree = {};
  parent = typeof parent !== 'undefined' ? parent : {id: 0};

  var childrenArray = array.filter(function(child) {
    return child.parentid == parent.id;
  });

  if (childrenArray.length > 0) {
    var childrenObject = {};
    // Transform children into a hash/object keyed on token
    childrenArray.forEach(function(child) {
      childrenObject[child.id] = child;
    });
    if (parent.id == 0) {
      tree = childrenObject;
    } else {
      parent['children'] = childrenObject;
    }
    childrenArray.forEach(function(child) {
      unflattenToObject(array, child);
    })
  }

  return tree;
};

var arr = [
    {'id':1 ,'parentid': 0},
    {'id':2 ,'parentid': 1},
    {'id':3 ,'parentid': 1},
    {'id':4 ,'parentid': 2},
    {'id':5 ,'parentid': 0},
    {'id':6 ,'parentid': 0},
    {'id':7 ,'parentid': 4}
];
tree = unflattenToObject(arr);

Create some nice new 10 year certificates and install them. The procedure is fairly easy.

Start at (1B) Generate your own CA (Certificate Authority) on this web page: Creating Certificate Authorities and self-signed SSL certificates and generate your CA Certificate and Key. Once you have these, generate your Server Certificate and Key. Create a Certificate Signing Request (CSR) and then sign the Server Key with the CA Certificate. Now install your Server Certificate and Key on the web server as usual, and import the CA Certificate into Internet Explorer's Trusted Root Certification Authority Store (used by the Flex uploader and Chrome as well) and into Firefox's Certificate Manager Authorities Store on each workstation that needs to access the server using the self-signed, CA-signed server key/certificate pair.

You now should not see any warning about using self-signed Certificates as the browsers will find the CA certificate in the Trust Store and verify the server key has been signed by this trusted certificate. Also in e-commerce applications like Magento, the Flex image uploader will now function in Firefox without the dreaded "Self-signed certificate" error message.

mysql> CREATE USER 'monty'@'192.168.%.%' IDENTIFIED BY 'some_pass';
mysql> GRANT ALL PRIVILEGES ON *.* TO 'monty'@'192.168.%.%'

Slight variation, main difference being to set the primary key field ("varname") to null, which produces a warning but works. By setting the primary key to null, the auto-increment works when inserting the record in the last statement.

This code also cleans up previous attempts, and can be run more than once without problems:

DELETE FROM `tbl` WHERE varname="primary key value for new record";
DROP TABLE tmp;
CREATE TEMPORARY TABLE tmp SELECT * FROM `tbl` WHERE varname="primary key value for old record";
UPDATE tmp SET varname=NULL;
INSERT INTO `tbl` SELECT * FROM tmp;

In Maven: The Definitive Guide, I wrote about the differences between Maven and Ant in the introduction the section title is "The Differences Between Ant and Maven". Here's an answer that is a combination of the info in that introduction with some additional notes.

A Simple Comparison

I'm only showing you this to illustrate the idea that, at the most basic level, Maven has built-in conventions. Here's a simple Ant build file:

<project name="my-project" default="dist" basedir=".">
    <description>
        simple example build file
    </description>   
    <!-- set global properties for this build -->   
    <property name="src" location="src/main/java"/>
    <property name="build" location="target/classes"/>
    <property name="dist"  location="target"/>

    <target name="init">
      <!-- Create the time stamp -->
      <tstamp/>
      <!-- Create the build directory structure used by compile -->
      <mkdir dir="${build}"/>   
    </target>

    <target name="compile" depends="init"
        description="compile the source " >
      <!-- Compile the java code from ${src} into ${build} -->
      <javac srcdir="${src}" destdir="${build}"/>  
    </target>

    <target name="dist" depends="compile"
        description="generate the distribution" >
      <!-- Create the distribution directory -->
      <mkdir dir="${dist}/lib"/>

      <!-- Put everything in ${build} into the MyProject-${DSTAMP}.jar file
-->
      <jar jarfile="${dist}/lib/MyProject-${DSTAMP}.jar" basedir="${build}"/>
   </target>

   <target name="clean"
        description="clean up" >
     <!-- Delete the ${build} and ${dist} directory trees -->
     <delete dir="${build}"/>
     <delete dir="${dist}"/>
   </target>
 </project>

In this simple Ant example, you can see how you have to tell Ant exactly what to do. There is a compile goal which includes the javac task that compiles the source in the src/main/java directory to the target/classes directory. You have to tell Ant exactly where your source is, where you want the resulting bytecode to be stored, and how to package this all into a JAR file. While there are some recent developments that help make Ant less procedural, a developer's experience with Ant is in coding a procedural language written in XML.

Contrast the previous Ant example with a Maven example. In Maven, to create a JAR file from some Java source, all you need to do is create a simple pom.xml, place your source code in ${basedir}/src/main/java and then run mvn install from the command line. The example Maven pom.xml that achieves the same results.

<project>
  <modelVersion>4.0.0</modelVersion>
  <groupId>org.sonatype.mavenbook</groupId>
  <artifactId>my-project</artifactId>
  <version>1.0</version>
</project>

That's all you need in your pom.xml. Running mvn install from the command line will process resources, compile source, execute unit tests, create a JAR, and install the JAR in a local repository for reuse in other projects. Without modification, you can run mvn site and then find an index.html file in target/site that contains links to JavaDoc and a few reports about your source code.

Admittedly, this is the simplest possible example project. A project which only contains source code and which produces a JAR. A project which follows Maven conventions and doesn't require any dependencies or customization. If we wanted to start customizing the behavior, our pom.xml is going to grow in size, and in the largest of projects you can see collections of very complex Maven POMs which contain a great deal of plugin customization and dependency declarations. But, even when your project's POM files become more substantial, they hold an entirely different kind of information from the build file of a similarly sized project using Ant. Maven POMs contain declarations: "This is a JAR project", and "The source code is in src/main/java". Ant build files contain explicit instructions: "This is project", "The source is in src/main/java", "Run javac against this directory", "Put the results in target/classses", "Create a JAR from the ....", etc. Where Ant had to be explicit about the process, there was something "built-in" to Maven that just knew where the source code was and how it should be processed.

High-level Comparison

The differences between Ant and Maven in this example? Ant...

• doesn't have formal conventions like a common project directory structure, you have to tell Ant exactly where to find the source and where to put the output. Informal conventions have emerged over time, but they haven't been codified into the product.
• is procedural, you have to tell Ant exactly what to do and when to do it. You had to tell it to compile, then copy, then compress.
• doesn't have a lifecycle, you had to define goals and goal dependencies. You had to attach a sequence of tasks to each goal manually.

Where Maven...

• has conventions, it already knew where your source code was because you followed the convention. It put the bytecode in target/classes, and it produced a JAR file in target.
• is declarative. All you had to do was create a pom.xml file and put your source in the default directory. Maven took care of the rest.
• has a lifecycle, which you invoked when you executed mvn install. This command told Maven to execute a series of sequence steps until it reached the lifecycle. As a side-effect of this journey through the lifecycle, Maven executed a number of default plugin goals which did things like compile and create a JAR.

What About Ivy?

Right, so someone like Steve Loughran is going to read that comparison and call foul. He's going to talk about how the answer completely ignores something called Ivy and the fact that Ant can reuse build logic in the more recent releases of Ant. This is true. If you have a bunch of smart people using Ant + antlibs + Ivy, you'll end up with a well designed build that works. Even though, I'm very much convinced that Maven makes sense, I'd happily use Ant + Ivy with a project team that had a very sharp build engineer. That being said, I do think you'll end up missing out on a number of valuable plugins such as the Jetty plugin and that you'll end up doing a whole bunch of work that you didn't need to do over time.

More Important than Maven vs. Ant

1. Is that you use a Repository Manager to keep track of software artifacts. I'd suggest downloading Nexus. You can use Nexus to proxy remote repositories and to provide a place for your team to deploy internal artifacts.
2. You have appropriate modularization of software components. One big monolithic component rarely scales over time. As your project develops, you'll want to have the concept of modules and sub-modules. Maven lends itself to this approach very well.
3. You adopt some conventions for your build. Even if you use Ant, you should strive to adopt some form of convention that is consistent with other projects. When a project uses Maven, it means that anyone familiar with Maven can pick up the build and start running with it without having to fiddle with configuration just to figure out how to get the thing to compile.

If you have the correct headers defined & are using a non GlibC library (such as Musl C) gcc will also throw error: implicit declaration of function when GNU extensions such as malloc_trim are encountered.

The solution is to wrap the extension & the header:

#if defined (__GLIBC__)
  malloc_trim(0);
#endif

Swift 5 version of Oleg Popov's answer, which is based on user1046037's answer

//Image View

In Oracle 12c, you can now specify the CURRVAL and NEXTVAL sequence pseudocolumns as default values for a column. Alternatively, you can use Identity columns; see:

• reference doc
• articles: Enhancements in Oracle DB 12cR1 (12.1): Default Values for Table Columns and Identity Columns in 12.1

E.g.,

CREATE SEQUENCE t1_seq;
CREATE TABLE t1 (
  id          NUMBER DEFAULT t1_seq.NEXTVAL,
  description VARCHAR2(30)
);

The question raised in 2014 and it's 2019 so I guess it's good to look for better option.

You can simply use fetch api in Javascript which provide you more flexibility.

for example, see this code

fetch('./api/some.json')
    .then((response) => {
        response.json().then((data) => { 
            ... 
        });
    })
    .catch((err) => { ... });

This is caused by node v12.11.0 due to the way it deals regular location there two ways to solve this problem

Method I

You can downgrade to node v12.10.0 this will apply the correct way to deal with parsing error

Method II

You can correctly terminate the regular expression in you case by changing the file located a:

\node_modules\metro-config\src\defaults\blacklist.js

From:

var sharedBlacklist = [
  /node_modules[/\\]react[/\\]dist[/\\].*/,
  /website\/node_modules\/.*/,
  /heapCapture\/bundle\.js/,
  /.*\/__tests__\/.*/
];

To:

 var sharedBlacklist = [
  /node_modules[\/\\]react[\/\\]dist[\/\\].*/,
  /website\/node_modules\/.*/,
  /heapCapture\/bundle\.js/,
  /.*\/__tests__\/.*/
];

Or if you need to set the value of found:

found = Value1.StartsWith("abc")

Edit: Given your edit, I would do something like:

found = Value1.Substring(0, 5).Contains("abc")

I'm guessing that either the class name is wrong - be sure to use the fully-resolved class name, with all packages - or it's not in the CLASSPATH so javap can't find it.

Use executeUpdate() to issue data manipulation statements. executeQuery() is only meant for SELECT queries (i.e. queries that return a result set).

If you want a generic error you can setup all $.ajax() (which $.get() uses underneath) requests jQuery makes to display an error using $.ajaxSetup(), for example:

$.ajaxSetup({
  error: function(xhr, status, error) {
    alert("An AJAX error occured: " + status + "\nError: " + error);
  }
});

Just run this once before making any AJAX calls (no changes to your current code, just stick this before somewhere). This sets the error option to default to the handler/function above, if you made a full $.ajax() call and specified the error handler then what you had would override the above.

To keep it down to a simple, reasonable response you can provide in an interview, I offer the following...

An interface is used to specify an API for a family of related classes - the relation being the interface. Typically used in a situation that has multiple implementations, the correct implementation being chosen either by configuration or at runtime. (Unless using Spring, at which point an interface is basically a Spring Bean). Interfaces are often used to solve the multiple inheritance issue.

An abstract class is a class designed specifically for inheritance. This also implies multiple implementations, with all implementations having some commonality (that found in the abstract class).

If you want to nail it, then say that an abstract class often implements a portion of an interface - job is yours!

Swift 3 version (butt_img must be an Image Set into Assets.xcassets or Images.xcassets folder in Xcode):

btnTwo.setBackgroundImage(UIImage(named: "butt_img"), for: .normal)
btnTwo.setTitle("My title", for: .normal)

Anyway, if you want the image to be scaled to fill the button's size, you may add a UIImageView over it and assign it your image:

let img = UIImageView()
img.frame = btnTwo.frame
img.contentMode = .scaleAspectFill
img.clipsToBounds = true
img.image = UIImage(named: "butt_img")
btnTwo.addSubview(img)

To the first part of your question - yes, browsers cache css files (if this is not disabled by browser's configuration). Many browsers have key combination to reload a page without a cache. If you made changes to css and want users to see them immediately instead of waiting next time when browser reloads the files without caching, you can change the way CSS ir served by adding some parameters to the url like this:

/style.css?modified=20012009

I did it this way with Bootstrap 4.3.1:

<div class="d-flex vh-100">
  <div class="d-flex w-100 justify-content-center align-self-center">
    I'm in the middle
  </div>
</div>

Don't grant control to the user, it's totally unnecessay. Select permission on the database is enough. After you have created the login and the user on master (see above answers):

use YourDatabase
go
create user [YourDomain\YourUser] for login [YourDomain\YourUser] with default_schema=[dbo]
go
alter role [db_datareader] add member [YourDomain\YourUser]
go

The CSS specification requires that position:fixed be anchored to the viewport, not the containing positioned element.

If you must specify your coordinates relative to a parent, you will have to use JavaScript to find the parent's position relative to the viewport first, then set the child (fixed) element's position accordingly.

ALTERNATIVE: Some browsers have sticky CSS support which limits an element to be positioned within both its container and the viewport. Per the commit message:

sticky ... constrains an element to be positioned inside the intersection of its container box, and the viewport.

A stickily positioned element behaves like position:relative (space is reserved for it in-flow), but with an offset that is determined by the sticky position. Changed isInFlowPositioned() to cover relative and sticky.

Depending on your design goals, this behavior may be helpful in some cases. It is currently a working draft, and has decent support, aside from table elements. position: sticky still needs a -webkit prefix in Safari.

See caniuse for up-to-date stats on browser support.

You can use indexOf(). Like:

var Color = ["blue", "black", "brown", "gold"];
var a = Color.indexOf("brown");
alert(a);

The indexOf() method searches the array for the specified item, and returns its position. And return -1 if the item is not found.

If you want to search from end to start, use the lastIndexOf() method:

    var Color = ["blue", "black", "brown", "gold"];
    var a = Color.lastIndexOf("brown");
    alert(a);

The search will start at the specified position, or at the end if no start position is specified, and end the search at the beginning of the array.

Returns -1 if the item is not found.

Double (called float in some languages) is fraut with problems due to rounding issues, it's good only if you need approximate values.

The Decimal data type does what you want.

For reference decimal and Decimal are the same in .NET C#, as are the double and Double types, they both refer to the same type (decimal and double are very different though, as you've seen).

Beware that the Decimal data type has some costs associated with it, so use it with caution if you're looking at loops etc.

INSERT INTO viewname (Column name) values (value);

I added @Component annotation from import org.springframework.stereotype.Component and the problem was solved.

HTML css works fine if body tag does nothing you can write as well

<body scroll="no" style="overflow: hidden">

In this case overriding should be on the body tag, it is easier to control but sometimes gives headaches.

One simplest way to encounter this is to use font awesome for example

 <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarCollapse" aria-controls="navbarCollapse" aria-expanded="false" aria-label="Toggle navigation">
       <span><i class="fas fa-bars"></i></span>
</button>

Then u can change the i element like you change any other ielement.

Not so hidden, but interesting.

Using the snippet provided by Richard, you can encrypt the password before saving it. The preferences API however doesn't provide an easy way to intercept the value and encrypt it - you can block it being saved via an OnPreferenceChange listener, and you theoretically could modify it through a preferenceChangeListener, but that results in an endless loop.

I had earlier suggested adding a "hidden" preference in order to accomplish this. It's definitely not the best way. I'm going to present two other options that I consider to be more viable.

First, the simplest, is in a preferenceChangeListener, you can grab the entered value, encrypt it, and then save it to an alternative preferences file:

  public boolean onPreferenceChange(Preference preference, Object newValue) {
      // get our "secure" shared preferences file.
      SharedPreferences secure = context.getSharedPreferences(
         "SECURE",
         Context.MODE_PRIVATE
      );
      String encryptedText = null;
      // encrypt and set the preference.
      try {
         encryptedText = SimpleCrypto.encrypt(Preferences.SEED,(String)newValue);

         Editor editor = secure.getEditor();
         editor.putString("encryptedPassword",encryptedText);
         editor.commit();
      }
      catch (Exception e) {
         e.printStackTrace();
      }
      // always return false.
      return false; 
   }

The second way, and the way I now prefer, is to create your own custom preference, extending EditTextPreference, @Override'ing the setText() and getText() methods, so that setText() encrypts the password, and getText() returns null.

Here's a simple method to do it: The (ip >> 8), (ip >> 16) and (ip >> 24) moves the 2nd, 3rd and 4th bytes into the lower order byte, while the & 0xFF isolates the least significant byte at each step.

void print_ip(unsigned int ip)
{
    unsigned char bytes[4];
    bytes[0] = ip & 0xFF;
    bytes[1] = (ip >> 8) & 0xFF;
    bytes[2] = (ip >> 16) & 0xFF;
    bytes[3] = (ip >> 24) & 0xFF;   
    printf("%d.%d.%d.%d\n", bytes[3], bytes[2], bytes[1], bytes[0]);        
}

There is an implied bytes[0] = (ip >> 0) & 0xFF; at the first step.

Use snprintf() to print it to a string.

There's no reason to use set unless referring to an object reference. It's good practice to only use it in that context. For all other simple data types, just use an assignment operator. It's a good idea to dim (dimension) ALL variables however:

Examples of simple data types would be integer, long, boolean, string. These are just data types and do not have their own methods and properties.

Dim i as Integer
i = 5

Dim myWord as String
myWord = "Whatever I want"

An example of an object would be a Range, a Worksheet, or a Workbook. These have their own methods and properties.

Dim myRange as Range
Set myRange = Sheet1.Range("A1")

If you try to use the last line without Set, VB will throw an error. Now that you have an object declared you can access its properties and methods.

myString = myRange.Value

Dplyr across function has superseded _if, _at, and _all. See vignette("colwise").

dat %>% 
mutate(across(all_of(l1), as.factor),
       across(all_of(l2), as.numeric))

IPv6 localhost

::1 is the loopback address in IPv6.

Within URLs

Within a URL, use square brackets []:

• http://[::1]/
  Defaults to port 80.
• http://[::1]:80/
  Specify port.

Enclosing the IPv6 literal in square brackets for use in a URL is defined in RFC 2732 – Format for Literal IPv6 Addresses in URL's.

=IIF(ISNOTHING(CStr(Fields!MyFields.Value)) or CStr(Fields!MyFields.Value) = "","-",CStr(Fields!MyFields.Value))

Use this expression you may get the answer.

Here CStr is an default function for handling String datatypes.

public static string textDataSource = "Data Source=localhost;Initial Catalog=TEST_C;User ID=sa;Password=P@ssw0rd";

public static DataSet LoaderDataSet(string StrSql)      
{
    SqlConnection cnn;            
    SqlDataAdapter dad;
    DataSet dts = new DataSet();
    cnn = new SqlConnection(textDataSource);
    dad = new SqlDataAdapter(StrSql, cnn);
    try
    {
        cnn.Open();
        dad.Fill(dts);
        cnn.Close();

        return dts;
    }
    catch (Exception)
    {

        return dts;
    }
    finally
    {
        dad.Dispose();
        dts = null;
        cnn = null;
    }
}

According to this nice FAQ there are a couple solutions.

You might also be able to escape the ampersand with the backslash character \ if you can modify the comment.

I have created a sorting function in Typescript which we can use to search strings, dates and numbers in array of objects. It can also sort on multiple fields.

export type SortType = 'string' | 'number' | 'date';
export type SortingOrder = 'asc' | 'desc';

export interface SortOptions {
  sortByKey: string;
  sortType?: SortType;
  sortingOrder?: SortingOrder;
}


class CustomSorting {
    static sortArrayOfObjects(fields: SortOptions[] = [{sortByKey: 'value', sortType: 'string', sortingOrder: 'desc'}]) {
        return (a, b) => fields
          .map((field) => {
            if (!a[field.sortByKey] || !b[field.sortByKey]) {
              return 0;
            }

            const direction = field.sortingOrder === 'asc' ? 1 : -1;

            let firstValue;
            let secondValue;

            if (field.sortType === 'string') {
              firstValue = a[field.sortByKey].toUpperCase();
              secondValue = b[field.sortByKey].toUpperCase();
            } else if (field.sortType === 'number') {
              firstValue = parseInt(a[field.sortByKey], 10);
              secondValue = parseInt(b[field.sortByKey], 10);
            } else if (field.sortType === 'date') {
              firstValue = new Date(a[field.sortByKey]);
              secondValue = new Date(b[field.sortByKey]);
            }
            return firstValue > secondValue ? direction : firstValue < secondValue ? -(direction) : 0;

          })
          .reduce((pos, neg) => pos ? pos : neg, 0);
      }
    }
}

Usage:

const sortOptions = [{
      sortByKey: 'anyKey',
      sortType: 'string',
      sortingOrder: 'asc',
    }];

arrayOfObjects.sort(CustomSorting.sortArrayOfObjects(sortOptions));

If you mean "non-alphanumeric characters", try to use this:

var reg =/[^a-zA-Z0-9]/g      //[^abc]

^[0-9]{1,45}$ is correct.

You can use:

print(df[df['Value']==df['Value'].max()])

You can take a look at InterpolatedUnivariateSpline

Here an example using it:

import matplotlib.pyplot as plt
import numpy as np
from scipy.interpolate import InterpolatedUnivariateSpline

# given values
xi = np.array([0.2, 0.5, 0.7, 0.9])
yi = np.array([0.3, -0.1, 0.2, 0.1])
# positions to inter/extrapolate
x = np.linspace(0, 1, 50)
# spline order: 1 linear, 2 quadratic, 3 cubic ... 
order = 1
# do inter/extrapolation
s = InterpolatedUnivariateSpline(xi, yi, k=order)
y = s(x)

# example showing the interpolation for linear, quadratic and cubic interpolation
plt.figure()
plt.plot(xi, yi)
for order in range(1, 4):
    s = InterpolatedUnivariateSpline(xi, yi, k=order)
    y = s(x)
    plt.plot(x, y)
plt.show()

I've tried deleting .suo; .ncb; .sdf; rebuild etc. Nothing helped. The message was:

Unable to start program
'C:\Users\some user\Downloads\project name\.\Debug\fil_name.exe'
The system cannot find the file specified.

The problem was mismatched file name and wrong path to that file.
1. So went to Project->Properties->Linker->General-> and on the right pane in 'Output file' changed the name from 'fil_name.exe' to 'file_name.exe'
The file_name.exe was in deeper folder like -> \Debug\crv.
2. Also did Project->Properties->Configuration Properties-> and on the right pane in 'Output Directory' edited '.\Debug\' to '.\Debug\crv'

The C standard (actually C99, I'm not up to date) says:

Alphabetic escape sequences representing nongraphic characters in the execution character set are intended to produce actions on display devices as follows:

\b (backspace) Moves the active position to the previous position on the current line. [...]

\t (horizontal tab) Moves the active position to the next horizontal tabulation position on the current line. [...]

Both just move the active position, neither are supposed to write any character on or over another character. To overwrite with a space you could try: puts("foo\b \tbar"); but note that on some display devices - say a daisy wheel printer - the o will show the transparent space.

// array of primitives:
int[] intArray = new int[] {1, 2, 3, 4, 5};

System.out.println(Arrays.toString(intArray));

output: [1, 2, 3, 4, 5]

// array of object references:
String[] strArray = new String[] {"John", "Mary", "Bob"};

System.out.println(Arrays.toString(strArray));

output: [John, Mary, Bob]

For the first one remove the spaces. Whitespace matters for the set command.

set guifont=Monaco:h20

For the second one it should be (the h specifies the height)

set guifont=Monospace:h20

My recommendation for setting the font is to do (if your version supports it)

set guifont=*

This will pop up a menu that allows you to select the font. After selecting the font, type

set guifont?

To show what the current guifont is set to. After that copy that line into your vimrc or gvimrc. If there are spaces in the font add a \ to escape the space.

set guifont=Monospace\ 20

This is a slightly difficult problem, which I think reduces to: "Test if two lists are permutations of each other."

I believe the solutions provided by others only indicate whether the 2 lists contain the same unique elements. This is a necessary but insufficient test, for example {1, 1, 2, 3} is not a permutation of {3, 3, 1, 2} although their counts are equal and they contain the same distinct elements.

I believe this should work though, although it's not the most efficient:

static bool ArePermutations<T>(IList<T> list1, IList<T> list2)
{
   if(list1.Count != list2.Count)
         return false;

   var l1 = list1.ToLookup(t => t);
   var l2 = list2.ToLookup(t => t);

   return l1.Count == l2.Count 
       && l1.All(group => l2.Contains(group.Key) && l2[group.Key].Count() == group.Count()); 
}

Another possibility is to use a set instead of a list, if a set is applicable in your application.

IE if your data is not ordered, and does not have duplicates, then

my_set=set([3,4,2])
my_set.discard(1)

is error-free.

Often a list is just a handy container for items that are actually unordered. There are questions asking how to remove all occurences of an element from a list. If you don't want dupes in the first place, once again a set is handy.

my_set.add(3)

doesn't change my_set from above.

Or just use the command line command:

Eventcreate

You use a self join when a table references data in itself.

E.g., an Employee table may have a SupervisorID column that points to the employee that is the boss of the current employee.

To query the data and get information for both people in one row, you could self join like this:

select e1.EmployeeID, 
    e1.FirstName, 
    e1.LastName,
    e1.SupervisorID, 
    e2.FirstName as SupervisorFirstName, 
    e2.LastName as SupervisorLastName
from Employee e1
left outer join Employee e2 on e1.SupervisorID = e2.EmployeeID

Change the auto_prepend_file property on php.ini

; Automatically add files before PHP document. 
;http://php.net/auto-prepend-file 
auto_prepend_file =

Simply use map function:

var arrOfObj = arrOfObj.map(function(element){
   element.active = true;
   return element;
}

Map is pretty decent on compatibility: you can be reasonably safe from IE <= 9.

However, if you are 100% sure your users will use ES6 Compatible browser, you can shorten that function with arrow functions, as @Sergey Panfilov has suggested.

I was able to use the answer outlined here: Export to CSV using jQuery and html and added in a modification to make it work in IE and another modification mentioned in the comments to grab the thead from the table.

function exportTableToCSV($table, filename) {

    var $rows = $table.find('tr:has(td),tr:has(th)'),

        // Temporary delimiter characters unlikely to be typed by keyboard
        // This is to avoid accidentally splitting the actual contents
        tmpColDelim = String.fromCharCode(11), // vertical tab character
        tmpRowDelim = String.fromCharCode(0), // null character

        // actual delimiter characters for CSV format
        colDelim = '","',
        rowDelim = '"\r\n"',

        // Grab text from table into CSV formatted string
        csv = '"' + $rows.map(function (i, row) {
            var $row = $(row), $cols = $row.find('td,th');

            return $cols.map(function (j, col) {
                var $col = $(col), text = $col.text();

                return text.replace(/"/g, '""'); // escape double quotes

            }).get().join(tmpColDelim);

        }).get().join(tmpRowDelim)
            .split(tmpRowDelim).join(rowDelim)
            .split(tmpColDelim).join(colDelim) + '"',



        // Data URI
        csvData = 'data:application/csv;charset=utf-8,' + encodeURIComponent(csv);

        console.log(csv);

        if (window.navigator.msSaveBlob) { // IE 10+
            //alert('IE' + csv);
            window.navigator.msSaveOrOpenBlob(new Blob([csv], {type: "text/plain;charset=utf-8;"}), "csvname.csv")
        } 
        else {
            $(this).attr({ 'download': filename, 'href': csvData, 'target': '_blank' }); 
        }
}

// This must be a hyperlink
$("#xx").on('click', function (event) {

    exportTableToCSV.apply(this, [$('#projectSpreadsheet'), 'export.csv']);

    // IF CSV, don't do event.preventDefault() or return false
    // We actually need this to be a typical hyperlink
});

With my link looking like this...

<a href="#" id="xx" style="text-decoration:none;color:#000;background-color:#ddd;border:1px solid #ccc;padding:8px;">Export Table data into Excel</a>

You can’t call non-static methods from static methods, but by creating an instance inside the static method.

It should work like that

class test2(object):
    def __init__(self):
        pass

    @staticmethod
    def dosomething():
        print "do something"
        # Creating an instance to be able to
        # call dosomethingelse(), or you
        # may use any existing instance
        a = test2()
        a.dosomethingelse()

    def dosomethingelse(self):
        print "do something else"

test2.dosomething()

As MySql accepts the date in y-m-d format in date type column, you need to STR_TO_DATE function to convert the date into yyyy-mm-dd format for insertion in following way:

INSERT INTO table_name(today) 
VALUES(STR_TO_DATE('07-25-2012','%m-%d-%y'));  

Similary, if you want to select the date in different format other than Mysql format, you should try DATE_FORMAT function

SELECT DATE_FORMAT(today, '%m-%d-%y') from table_name;

If a value in YAML begins with a curly brace ({), the YAML parser assumes that it is a dictionary. So, for cases like this where there is a (Jinja2) variable in the value, one of the following two strategies needs to be adopted to avoiding confusing the YAML parser:

Quote the whole command:

- command: "{{ item }} chdir=/src/package/"
  with_items:
  - ./configure
  - /usr/bin/make
  - /usr/bin/make install    

or change the order of the arguments:

- command: chdir=/src/package/ {{ item }}
  with_items:
  - ./configure
  - /usr/bin/make
  - /usr/bin/make install

Thanks for @RamondelaFuente alternative suggestion.

late to the game on this... i too have yet another permutation of JarodPar's answer.

here's Type.IsSubClassOf(Type) courtesy of reflector:

    public virtual bool IsSubclassOf(Type c)
    {
        Type baseType = this;
        if (!(baseType == c))
        {
            while (baseType != null)
            {
                if (baseType == c)
                {
                    return true;
                }
                baseType = baseType.BaseType;
            }
            return false;
        }
        return false;
    }

from that, we see that it's not doing anything too cray cray and is similar to JaredPar's iterative approach. so far, so good. here's my version (disclaimer: not thoroughly tested, so lemme know if you find issues)

    public static bool IsExtension(this Type thisType, Type potentialSuperType)
    {
        //
        // protect ya neck
        //
        if (thisType == null || potentialSuperType == null || thisType == potentialSuperType) return false;

        //
        // don't need to traverse inheritance for interface extension, so check/do these first
        //
        if (potentialSuperType.IsInterface)
        {
            foreach (var interfaceType in thisType.GetInterfaces())
            {
                var tempType = interfaceType.IsGenericType ? interfaceType.GetGenericTypeDefinition() : interfaceType;

                if (tempType == potentialSuperType)
                {
                    return true;
                }
            }
        }

        //
        // do the concrete type checks, iterating up the inheritance chain, as in orignal
        //
        while (thisType != null && thisType != typeof(object))
        {
            var cur = thisType.IsGenericType ? thisType.GetGenericTypeDefinition() : thisType;

            if (potentialSuperType == cur)
            {
                return true;
            }

            thisType = thisType.BaseType;
        }
        return false;
    }

basically this is just an extension method to System.Type - i did this to intentionally limit the "thisType" Type to concrete Types, as my immediate usage is to LINQ query "where" predicates against Type objects. i'm sure all you smart folks out there could bang it down to an efficient, all-purpose static method if you need to :) the code does a few things the answer's code doesn't

1. open's it up to to general "extension" - i'm considering inheritance (think classes) as well as implementation (interfaces); method and parameter names are changed to better reflect this
2. input null-validation (meah)
3. input of same type (a class cannot extend itself)
4. short-circuit execution if Type in question is an interface; because GetInterfaces() returns all implemented interfaces (even ones implemented in super-classes), you can simply loop through that collection not having to climb the inheritance tree

the rest is basically the same as JaredPar's code

You can also do it one line:

int hello = Integer.parseInt(((Button)findViewById(R.id.button1)).getText().toString().replaceAll("[\\D]", ""));

Reading from order of execution

1. grab the view using findViewById(R.id.button1)
2. use ((Button)______) to cast the View as a Button
3. Call .GetText() to get the text entry from Button
4. Call .toString() to convert the Character Varying to a String
5. Call .ReplaceAll() with "[\\D]" to replace all Non Digit Characters with "" (nothing)
6. Call Integer.parseInt() grab and return an integer out of the Digit-only string.

I share your sense that Interfaces are not necessary. Here is a quote from Cwalina pg 80 Framework Design Guidelines "I often here people saying that interfaces specify contracts. I believe this a dangerous myth. Interfaces by themselves do not specify much. ..." He and co-author Abrams managed 3 releases of .Net for Microsoft. He goes on to say that the 'contract' is "expressed" in an implementation of the class. IMHO watching this for decades, there were many people warning Microsoft that taking the engineering paradigm to the max in OLE/COM might seem good but its usefulness is more directly to hardware. Especially in a big way in the 80s and 90s getting interoperating standards codified. In our TCP/IP Internet world there is little appreciation of the hardware and software gymnastics we would jump through to get solutions 'wired up' between and among mainframes, minicomputers, and microprocessors of which PCs were just a small minority. So coding to interfaces and their protocols made computing work. And interfaces ruled. But what does solving making X.25 work with your application have in common with posting recipes for the holidays? I have been coding C++ and C# for many years and I never created one once.

In Angular 4, you can use environment class to keep all your globals.

You have environment.ts and environment.prod.ts by default.

For example

export const environment = {
  production: false,
  apiUrl: 'http://localhost:8000/api/'
};

And then on your service:

import { environment } from '../../environments/environment';
...
environment.apiUrl;

A long-term solution: userscript

You can use a userscript like Tampermonkey (if you are using Chrome or Edge-Chromium, here is the extension)

Then create a script and paste this in it:

// ==UserScript==
// @name         Google docs
// @include      https://*docs.google.*/document/*
// @grant    GM_addStyle
// ==/UserScript==

GM_addStyle ( `
    .kix-page-compact::before {
        border-top: none;
    }
` );

A temporary fix: developer console

You can use the developper console. In Chrome:
1. open your document on google docs
2. click in the url field and press ctrl+shift+I (or right click just above help and select "view page source)

Then modify the css (cf the steps on the printscreen below) :
1. once the console is loaded press ctrl+F and paste this : kix-page kix-page-compact
2. click on the div just below the one that is highlighted in yellow
3. in the right part, paste this in the filter box : .kix-page-compact::before
4. click on 1px dotted #aaa next to border-top and replace it by none

Change the code where you load the partial view to:

@Html.Partial("_CreateNote", new QuickNotes.Models.Note())

This is because the partial view is expecting a Note but is getting passed the model of the parent view which is the IEnumerable

From client side, I cant solve this problem. From nodejs express side, you can use cors module to handle it.

var express       = require('express');
var app           = express();
var bodyParser = require('body-parser');
var cors = require('cors');

var port = 3000; 
var ip = '127.0.0.1';

app.use('*/myapi', 
          cors(), // with this row OPTIONS has handled
          bodyParser.text({type:'text/*'}),
          function( req, res, next ){
    console.log( '\n.----------------' + req.method + '------------------------' );
        console.log( '| prot:'+req.protocol );
        console.log( '| host:'+req.get('host') );
        console.log( '| url:'+req.originalUrl );
        console.log( '| body:',req.body );
        //console.log( '| req:',req );
    console.log( '.----------------' + req.method + '------------------------' );
    next();
    });

app.listen(port, ip, function() {
    console.log('Listening to port:  ' + port );
});
 
console.log(('dir:'+__dirname ));
console.log('The server is up and running at http://'+ip+':'+port+'/');

Without cors() this OPTIONS has appears before POST.

.----------------OPTIONS------------------------
| prot:http
| host:localhost:3000
| url:/myapi
| body: {}
.----------------OPTIONS------------------------

.----------------POST------------------------
| prot:http
| host:localhost:3000
| url:/myapi
| body: <SOAP-ENV:Envelope .. P-ENV:Envelope>
.----------------POST------------------------

The ajax call:

$.ajax({
    type: 'POST',
    contentType: "text/xml; charset=utf-8",
// these does not works
    //beforeSend: function(request) { 
    //  request.setRequestHeader('Content-Type', 'text/xml; charset=utf-8');
    //  request.setRequestHeader('Accept', 'application/vnd.realtime247.sct-giro-v1+cms');
    //  request.setRequestHeader('Access-Control-Allow-Origin', '*');
    //  request.setRequestHeader('Access-Control-Allow-Methods', 'POST, GET');
    //  request.setRequestHeader('Access-Control-Allow-Headers', 'Origin, X-Requested-With, Content-Type');
    //},
    //headers: {
    //  'Content-Type': 'text/xml; charset=utf-8',
    //  'Accept': 'application/vnd.realtime247.sct-giro-v1+cms',
    //  'Access-Control-Allow-Origin': '*',
    //  'Access-Control-Allow-Methods': 'POST, GET',
    //  'Access-Control-Allow-Headers': 'Origin, X-Requested-With, Content-Type'
    //},
    url: 'http://localhost:3000/myapi',             
    data:       '<SOAP-ENV:Envelope .. P-ENV:Envelope>',                
    success: function( data ) {
      console.log(data.documentElement.innerHTML);
    },
    error: function(jqXHR, textStatus, err) {
      console.log( jqXHR,'\n', textStatus,'\n', err )
    }
  });

Remove the get_figure and just use sns_plot.savefig('output.png')

df = sns.load_dataset('iris')
sns_plot = sns.pairplot(df, hue='species', height=2.5)
sns_plot.savefig("output.png")

You can also use replaceAll:

String uri = "http://base_path/some_segment/id"
String lastSegment = uri.replaceAll(".*/", "")

System.out.println(lastSegment);

result:

id

I like to use such static methods:

$result = $purchases_repository->matching(
    Criteria::create()->where(
        Criteria::expr()->gt('prize', 200)
    )
);

Of course, you can push logic when it is 1 condition, but when you have more conditions it is better to divide it into fragments, configure and pass it to the method:

$expr = Criteria::expr();

$criteria = Criteria::create();
$criteria->where($expr->gt('prize', 200));
$criteria->orderBy(['prize' => Criteria::DESC]);

$result = $purchases_repository->matching($criteria);

/*sorry this is the correct */

     public byte[] IntArrayToByteArray(int[] iarray , int sizeofintarray)
     {
       final ByteBuffer bb ;
       bb = ByteBuffer.allocate( sizeofintarray * 4);
       for(int k = 0; k < sizeofintarray ; k++)
       bb.putInt(k * 4, iar[k]);
       return bb.array();
     }

In my case, I install 32 Bit Python so I cannot install Tensorflow, After uninstall 32 Bit Python and install 64 Bit Python, I can install tensorflow successfully.

After reinstall Python 64 bit, you need to check your python install folder path is properly set in Windows Environment Path.

You can check Python version by typing python in cmd.

you could also try;

data = pd.read_csv('file1.csv', error_bad_lines=False)

Do note that this will cause the offending lines to be skipped.

Under Windows 10, the Task Manager can show you cumulative CPU hours. Just head to the "App history" tab and "Delete usage history". Now leave things running for an hour or two:

What this does NOT do is break down usage in browsers by tab. Quite often inactive tabs will do a tremendous amount of work, with each open tab using energy and slowing your PC.

Coming here from first Google hit:

You can turn off the behavior AND and warning by exporting GIT_DISCOVERY_ACROSS_FILESYSTEM=1.

On heroku, if you heroku config:set GIT_DISCOVERY_ACROSS_FILESYSTEM=1 the warning will go away.

It's probably because you are building a gem from source and the gemspec shells out to git, like many do today. So, you'll still get the warning fatal: Not a git repository (or any of the parent directories): .git but addressing that is for another day :)

My answer is a duplicate of: - comment GIT_DISCOVERY_ACROSS_FILESYSTEM problem when working with terminal and MacFusion

FIXED IT!

I was losing my mind over this one. Reset firefox, tried safe mode, removed plugins, debugged using developers tools. All were to no avail and didn't get me any further with getting my online videos back to normal viewing condition. This however did the trick perfectly.

Within Firefox or whatever flavor of Firefox you have(CyberFox being my favorite choice here), simply browse to https://get.adobe.com/flashplayer/

VERIFY FIRST that the website detected you're using FireFox and has set your download for the flash player to be for Firefox.

Don't just click download. PLEASE PLEASE PLEASE SAVE YOURSELF the migraine and ALWAYS make sure that the middle section labeled "Optional offer:" is absolutely NOT CHECKED, it will be checked by default so always UNCHECK it before proceeding to download.

After it's finished downloading, close out of Firefox. Run the downloaded setup file As Administrator. It takes only a few seconds or so to complete, so after it's done, open up Firefox again and try viewing anything that was previously throwing this error. Should be back to normal now.

Enjoy!

if you're uncomfortable with returning addresses and have just a single variable eg. an integer value to return, you can even typecast it into (void *) before passing it, and then when you collect it in the main, again typecast it into (int). You have the value without throwing up ugly warnings.

A later answer, but because no one gave this solution...

If you do not want to set the header on the HttpClient instance by adding it to the DefaultRequestHeaders, you could set headers per request.

But you will be obliged to use the SendAsync() method.

This is the right solution if you want to reuse the HttpClient -- which is a good practice for

• performance and port exhaustion problems
• doing something thread-safe
• not sending the same headers every time

Use it like this:

using (var requestMessage =
            new HttpRequestMessage(HttpMethod.Get, "https://your.site.com"))
{
    requestMessage.Headers.Authorization =
        new AuthenticationHeaderValue("Bearer", your_token);
    httpClient.SendAsync(requestMessage);
}

If your numbers are a, b and c then:

    int a = 1;
    int b = 2;
    int c = 3;

    int d =  a > b ? a : b;
    return c > d ? c : d;

This could turn into one of those "how many different ways can we do this" type questions!

I think the exact answer is: for api 11 or higher:

getActionBar().setDisplayShowHomeEnabled(false);

otherwise:

getSupportActionBar().setDisplayShowHomeEnabled(false);

(because it need a support library.)

I'm using GDB7.1.1, as --help shows:

gdb [options] --args executable-file [inferior-arguments ...]

IMHO, the order is a bit unintuitive at first.

Thank you Rob W for your answer.

I have been using this within a Cordova application to avoid having to load the API and so that I can easily control iframes which are loaded dynamically.

I always wanted the ability to be able to extract information from the iframe, such as the state (getPlayerState) and the time (getCurrentTime).

Rob W helped highlight how the API works using postMessage, but of course this only sends information in one direction, from our web page into the iframe. Accessing the getters requires us to listen for messages posted back to us from the iframe.

It took me some time to figure out how to tweak Rob W's answer to activate and listen to the messages returned by the iframe. I basically searched through the source code within the YouTube iframe until I found the code responsible for sending and receiving messages.

The key was changing the 'event' to 'listening', this basically gave access to all the methods which were designed to return values.

Below is my solution, please note that I have switched to 'listening' only when getters are requested, you can tweak the condition to include extra methods.

Note further that you can view all messages sent from the iframe by adding a console.log(e) to the window.onmessage. You will notice that once listening is activated you will receive constant updates which include the current time of the video. Calling getters such as getPlayerState will activate these constant updates but will only send a message involving the video state when the state has changed.

function callPlayer(iframe, func, args) {
    iframe=document.getElementById(iframe);
    var event = "command";
    if(func.indexOf('get')>-1){
        event = "listening";
    }

    if ( iframe&&iframe.src.indexOf('youtube.com/embed') !== -1) {
      iframe.contentWindow.postMessage( JSON.stringify({
          'event': event,
          'func': func,
          'args': args || []
      }), '*');
    }
}
window.onmessage = function(e){
    var data = JSON.parse(e.data);
    data = data.info;
    if(data.currentTime){
        console.log("The current time is "+data.currentTime);
    }
    if(data.playerState){
        console.log("The player state is "+data.playerState);
    }
}

Is above javascript code the one you're using in your web application ? If so - i would like to point few errors in it: firstly - it has an additional '{' sign in definition of 'success' callback function secondly - it has no ')' sign after definition of ajax callback. Valid code should look like:

$.ajax({
        type:'POST',
        data: 'args',
        url: '@Url.Action("PostBack")',
        success: function (data, textStatus, jqXHR) {
                alert(data.message);
            }
    });

try using above code - it gave me 'Yay' alert on all 3 IE versions ( 7,8,9 ).

There is no built-in method, but there are several ways to do it. The most straightforward way that I can think of at the moment is:

1. Create a subclass of JComponent.
2. Override the paintComponent(Graphics g) method to paint the image that you want to display.
3. Set the content pane of the JFrame to be this subclass.

Some sample code:

class ImagePanel extends JComponent {
    private Image image;
    public ImagePanel(Image image) {
        this.image = image;
    }
    @Override
    protected void paintComponent(Graphics g) {
        super.paintComponent(g);
        g.drawImage(image, 0, 0, this);
    }
}

// elsewhere
BufferedImage myImage = ImageIO.read(...);
JFrame myJFrame = new JFrame("Image pane");
myJFrame.setContentPane(new ImagePanel(myImage));

Note that this code does not handle resizing the image to fit the JFrame, if that's what you wanted.

Might be, more safe alternative to "_ORACLE_SCRIPT"=true is to change "_common_user_prefix" from C## to an empty string. When it's null - any name can be used for common user. Found there.

During changing that value you may face another issue - ORA-02095 - parameter cannot be modified, that can be fixed in a several ways, based on your configuration (source).

So for me worked that:

alter system set _common_user_prefix = ''; scope=spfile;

Based on win7. Eclipse Version: 4.2.2 Build id: M20130204-1200

For those who broke Eclipse after trying to uninstall ADT plugin.

You need to remove all android folder/jars from plugin folder and features folder.

Then check your config.ini in /configuration. Probably you have these lines:

eclipse.product=

...

eclipse.application=

change them like this:

eclipse.product=org.eclipse.platform.ide
eclipse.application=org.eclipse.ui.ide.workbench

Maybe needed to run your eclipse from command line:

eclipsec.exe -clean.

Then I could install the newest ADT plugin, without needing to download whole eclipse packages and loosing all configuration/plugins.

For me it was the version. Yes, the line you put at the root, like :

{
    "name": "your-project",
    "version": "0.1"
    ...
}

Yes, npm doesn't like version like this, it prefers something like "0.0.1".

Don't ask me why, I'll tell you it's totally stupid (or "how to loose time easily")

Something I did for showing gifs in apps. I extended ImageView so people can use its attributes freely. It can show gifs from url or from the assets directory. The library also makes it easy for extending classes to inherit from it and extend it to support different methods to initialize the gif.

https://github.com/Gavras/GIFView

There's a little guide on the github page.

It was also published on Android Arsenal:

https://android-arsenal.com/details/1/4947

Use example:

From XML:

<com.whygraphics.gifview.gif.GIFView xmlns:gif_view="http://schemas.android.com/apk/res-auto"
        android:id="@+id/main_activity_gif_vie"
        android:layout_width="200dp"
        android:layout_height="200dp"
        android:scaleType="center"
        gif_view:gif_src="url:http://pop.h-cdn.co/assets/16/33/480x264/gallery-1471381857-gif-season-2.gif" />

In the activity:

    GIFView mGifView = (GIFView) findViewById(R.id.main_activity_gif_vie);

    mGifView.setOnSettingGifListener(new GIFView.OnSettingGifListener() {
                @Override
                public void onSuccess(GIFView view, Exception e) {
                    Toast.makeText(MainActivity.this, "onSuccess()", Toast.LENGTH_SHORT).show();
                }

                @Override
                public void onFailure(GIFView view, Exception e) {

        }
});

Setting the gif programmatically:

mGifView.setGifResource("asset:gif1");

What are non-recursive mutexes good for?

They are absolutely good when you have to make sure the mutex is unlocked before doing something. This is because pthread_mutex_unlock can guarantee that the mutex is unlocked only if it is non-recursive.

pthread_mutex_t      g_mutex;

void foo()
{
    pthread_mutex_lock(&g_mutex);
    // Do something.
    pthread_mutex_unlock(&g_mutex);

    bar();
}

If g_mutex is non-recursive, the code above is guaranteed to call bar() with the mutex unlocked.

Thus eliminating the possibility of a deadlock in case bar() happens to be an unknown external function which may well do something that may result in another thread trying to acquire the same mutex. Such scenarios are not uncommon in applications built on thread pools, and in distributed applications, where an interprocess call may spawn a new thread without the client programmer even realising that. In all such scenarios it's best to invoke the said external functions only after the lock is released.

If g_mutex was recursive, there would be simply no way to make sure it is unlocked before making a call.

On the server, try:

netstat -an 

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

Here is the workaround:

In eclipse.ini write the following:

-vmargs
-Dorg.eclipse.ecf.provider.filetransfer.excludeContributors= org.eclipse.ecf.provider.filetransfer.httpclient
-Dhttp.proxyHost=*myproxyhost*
-Dhttp.proxyPort=*myproxyport*
-Dhttp.proxyUser=*proxy username*
-Dhttp.proxyPassword=*proxy password*
-Dhttp.nonProxyHosts=localhost|127.0.0.1

After starting eclipse verify, that you use the Manual proxy method.

HTH

Equivalent will be

ADD_MONTHS( SYSDATE, -6 )

You should add dataType: "html" to the request. Im quite sure you wont be able to search the DOM of the returned html if it doesnt know it is html.

You can avoid the loop and cut etc by using:

awk -F ':' '{system("ping " $1);}' config.txt

However it would be better if you post a snippet of your config.txt

I've moved from a terminal text-editor+make environment to Eclipse for most of my projects. Spanning from C and C++, to Java and Python to name few languages I am currently working with.

The reason was simply productivity. I could not afford spending time and effort on keeping all projects "in my head" as other things got more important.

There are benefits of using the "hardcore" approach (terminal) - such as that you have a much thinner layer between yourself and the code which allows you to be a bit more productive when you're all "inside" the project and everything is on the top of your head. But I don't think it is possible to defend that way of working just for it's own sake when your mind is needed elsewhere.

Usually when you work with command line tools you will frequently have to solve a lot of boilerplate problems that will keep you from being productive. You will need to know the tools in detail to fully leverage their potentials. Also maintaining a project will take a lot more effort. Refactoring will lead to updates in make-files, etc.

To summarize: If you only work on one or two projects, preferably full-time without too much distractions, "terminal based coding" can be more productive than a full blown IDE. However, if you need to spend your thinking energy on something more important an IDE is definitely the way to go in order to keep productivity.

Make your choice accordingly.

make sure your controller extends Symfony\Bundle\FrameworkBundle\Controller\Controller;

you should also check app/console debug:router in terminal to see what name symfony has named the route

in my case it used a minus instead of an underscore

i.e blog-show

$uri = $this->generateUrl('blog-show', ['slug' => 'my-blog-post']);

Check the API Docs

Methods addOption(data) and setValue(value) might be what you are looking for.

Update: Seeing the popularity of this answer, here is some additional info based on comments/requests...

setValue(value, silent)
Resets the selected items to the given value.
If "silent" is truthy (ie: true, 1), no change event will be fired on the original input.

addOption(data)
Adds an available option, or array of options. If it already exists, nothing will happen.
Note: this does not refresh the options list dropdown (use refreshOptions() for that).

In response to options being overwritten:
This can happen by re-initializing the select without using the options you initially provided. If you are not intending to recreate the element, simply store the selectize object to a variable:

// 1. Only set the below variables once (ideally)
var $select = $('select').selectize(options);  // This initializes the selectize control
var selectize = $select[0].selectize; // This stores the selectize object to a variable (with name 'selectize')

// 2. Access the selectize object with methods later, for ex:
selectize.addOption(data);
selectize.setValue('something', false);


// Side note:
// You can set a variable to the previous options with
var old_options = selectize.settings;
// If you intend on calling $('select').selectize(old_options) or something

This is not a system font. this font is not supported in other systems. you can use font-face, convert font from this Site or from this

Static methods are not associated with an instance, so they can not access any non-static fields in the class.

You would use a static method if the method does not use any fields (or only static fields) of a class.

If any non-static fields of a class are used you must use a non-static method.

'Killing a thread' is not the right phrase to use. Here is one way we can implement graceful completion/exit of the thread on will:

Runnable which I used:

class TaskThread implements Runnable {

    boolean shouldStop;

    public TaskThread(boolean shouldStop) {
        this.shouldStop = shouldStop;
    }

    @Override
    public void run() {

        System.out.println("Thread has started");

        while (!shouldStop) {
            // do something
        }

        System.out.println("Thread has ended");

    }

    public void stop() {
        shouldStop = true;
    }

}

The triggering class:

public class ThreadStop {

    public static void main(String[] args) {

        System.out.println("Start");

        // Start the thread
        TaskThread task = new TaskThread(false);
        Thread t = new Thread(task);
        t.start();

        // Stop the thread
        task.stop();

        System.out.println("End");

    }

}

According to the grammar in the CSP spec, you need to specify schemes as scheme:, not just scheme. So, you need to change the image source directive to:

img-src 'self' data:;

What you want is the outer HTML, not the inner HTML :

$('<some element/>')[0].outerHTML;

It turns out that lstlisting is able to format code nicely, but requires a lot of tweaking.

Wikibooks has a good example for the parameters you can tweak.

You can only use

     Object& return_Object();

if the object returned has a greater scope than the function. For example, you can use it if you have a class where it is encapsulated. If you create an object in your function, use pointers. If you want to modify an existing object, pass it as an argument.

  class  MyClass{
      private:
        Object myObj;

      public:
         Object& return_Object() {
            return myObj;
         }

         Object* return_created_Object() {
            return new Object();
         }

         bool modify_Object( Object& obj) {
            //  obj = myObj; return true; both possible
            return obj.modifySomething() == true;
         }
   };
