Looks like the setup.py uses easy_install (i.e. setuptools). Just install the setuptools package and you will be all set.

To install setuptools in Python 2.6, see the answer to this question.

Or even shorter, with only standard modern Javascript:

var first_link = document.getElementsByTagName('a')[0];
first_link.dispatchEvent(new MouseEvent('click'));

The new MouseEvent constructor takes a required event type name, then an optional object (at least in Chrome). So you could, for example, set some properties of the event:

first_link.dispatchEvent(new MouseEvent('click', {bubbles: true, cancelable: true}));

According to the question html5 validity should be validate able using jQuery at first and in most of the answer this is not happening and the reason for this is as following:

while validating using html5 form's default function

checkValidity();// returns true/false

we need to understand that jQuery returns object array, while selecting like this

$("#myForm")

therefore, you need to specify the first index to make checkValidity() function work

$('#myForm')[0].checkValidity()

here is the complete solution:

<button type="button" name="button" onclick="saveData()">Save</button>

function saveData()
{
    if($('#myForm')[0].checkValidity()){
        $.ajax({
          type: "POST",
          url: "save.php",
          data: data,
          success: function(resp){console.log("Response: "+resp);}
        });
    }
}

You can make cross domain requests using the XMLHttpRequest object. This is done using something called "Cross Origin Resource Sharing". See: http://en.wikipedia.org/wiki/Cross-origin_resource_sharing

Very simply put, when the request is made to the server the server can respond with a Access-Control-Allow-Origin header which will either allow or deny the request. The browser needs to check this header and if it is allowed then it will continue with the request process. If not the browser will cancel the request.

You can find some more information and a working example here: http://www.leggetter.co.uk/2010/03/12/making-cross-domain-javascript-requests-using-xmlhttprequest-or-xdomainrequest.html

JSONP is an alternative solution, but you could argue it's a bit of a hack.

You can change the value of the referrer in the HTTP header using the Web Request API.

It requires a background js script for it's use. You can use the onBeforeSendHeaders as it modifies the header before the request is sent.

Your code will be something like this :

    chrome.webRequest.onBeforeSendHeaders.addEventListener(function(details){
    var newRef = "http://new-referer/path";
    var hasRef = false;
    for(var n in details.requestHeaders){
        hasRef = details.requestHeaders[n].name == "Referer";
        if(hasRef){
            details.requestHeaders[n].value = newRef;
         break;
        }
    }
    if(!hasRef){
        details.requestHeaders.push({name:"Referer",value:newRef});
    }
    return {requestHeaders:details.requestHeaders};
},
{
    urls:["http://target/*"]
},
[
    "requestHeaders",
    "blocking"
]);

urls : It acts as a request filter, and invokes the listener only for certain requests.

ser.read(64) should be ser.read(size=64); ser.read uses keyword arguments, not positional.

Also, you're reading from the port twice; what you probably want to do is this:

i=0
for modem in PortList:
    for port in modem:
        try:
            ser = serial.Serial(port, 9600, timeout=1)
            ser.close()
            ser.open()
            ser.write("ati")
            time.sleep(3)
            read_val = ser.read(size=64)
            print read_val
            if read_val is not '':
                print port
        except serial.SerialException:
            continue
        i+=1

May be it's good if you define your background-image in the :after pseudo class. Write like this:

.parent{
    width:300px;
    height:300px;
    position:relative;
    border:1px solid red;
}
.parent:after{
    content:'';
    background:url('http://www.dummyimage.com/300x300/000/fff&text=parent+image');
    width:300px;
    height:300px;
    position:absolute;
    top:0;
    left:0;
    opacity:0.5;
}
.child{
    background:yellow;
    position:relative;
    z-index:1;
}

There is a nuance to updating tables then updating the DBML... Foreign key relationships are not immediately always brought over if changes are made to existing tables. The work around is to do a build of the project and then re-add the tables again. I reported this to MS and its being fixed for VS2010.

DBML display does not show new foreign key constraints

Note that the instructions given in the main answer are not clear. To update the table

1. Open up the dbml design surface
2. Select all tables with Right->Click->Select All or CTRLa
3. CTRLx (Cut)
4. CTRLv (Paste)
5. Save and rebuild solution.

You refer to 'x' from window object

var x = 0;

function a(key, ref) {
    ref = ref || window;  // object reference - default window
    ref[key]++;
}

a('x');                   // string
alert(x);

• Install Node js - https://nodejs.org/en/

• go to folder where you have html file:

  • In CMD, run the command to install http server- npm install http-server -g
  • To load file in the browser run - http-server

• If you have specific html file. Run following command in CMD.- http-server fileName

• by default port is 8080

• Go to your browser and type localhost:8080. Your Application should run there.

• If you want to run on different port: http-server fileName -p 9000

Note : To run your .js file run: node fileName.js

I also had the same issue. I also tried to look for solutions, but after I didn't find any of the solutions working, I tried to restart my mobile (Android device), and it resolved the issue.

Please give it a try! Restart your mobile device and Eclipse to be on safe side and check if it works.

You can update with MERGE Command with much more control over MATCHED and NOT MATCHED:(I slightly changed the source code to demonstrate my point)

USE tempdb;
GO
IF(OBJECT_ID('target') > 0)DROP TABLE dbo.target
IF(OBJECT_ID('source') > 0)DROP TABLE dbo.source
CREATE TABLE dbo.Target
    (
      EmployeeID INT ,
      EmployeeName VARCHAR(100) ,
      CONSTRAINT Target_PK PRIMARY KEY ( EmployeeID )
    );
CREATE TABLE dbo.Source
    (
      EmployeeID INT ,
      EmployeeName VARCHAR(100) ,
      CONSTRAINT Source_PK PRIMARY KEY ( EmployeeID )
    );
GO
INSERT  dbo.Target
        ( EmployeeID, EmployeeName )
VALUES  ( 100, 'Mary' );
INSERT  dbo.Target
        ( EmployeeID, EmployeeName )
VALUES  ( 101, 'Sara' );
INSERT  dbo.Target
        ( EmployeeID, EmployeeName )
VALUES  ( 102, 'Stefano' );

GO
INSERT  dbo.Source
        ( EmployeeID, EmployeeName )
VALUES  ( 100, 'Bob' );
INSERT  dbo.Source
        ( EmployeeID, EmployeeName )
VALUES  ( 104, 'Steve' );
GO

SELECT * FROM dbo.Source
SELECT * FROM dbo.Target

MERGE Target AS T
USING Source AS S
ON ( T.EmployeeID = S.EmployeeID )
WHEN MATCHED THEN
    UPDATE SET T.EmployeeName = S.EmployeeName + '[Updated]';
GO 
SELECT '-------After Merge----------'
SELECT * FROM dbo.Source
SELECT * FROM dbo.Target

Below is worked for me on macos mojave 10.14.6 version

I installed current jdk(https://www.oracle.com/java/technologies/javase-downloads.html)

Then do respectively;

• vim .bash_profile
• add "export JAVA_HOME=$(/usr/libexec/java_home)" to bash_profile
• source .bash_profile

it is done. And you can check the version with java -version command.

You don't need a for loop in your code.

Here is how you can re implement your method

• If input is between 'A' and 'Z' its uppercase
• If input is between 'a' and 'z' its lowercase
• If input is one of 'a,e,i,o,u,A,E,I,O,U' its Vowel
• Else Consonant

Edit:

Here is hint for you to proceed, Following code snippet gives int values for chars

System.out.println("a="+(int)'a');
System.out.println("z="+(int)'z');
System.out.println("A="+(int)'A');
System.out.println("Z="+(int)'Z');

Output

a=97
z=122
A=65
Z=90

Here is how you can check if a number x exists between two numbers say a and b

// x greater than or equal to a and x less than or equal to b
if ( x >= a && x <= b ) 

During comparisons chars can be treated as numbers

If you can combine these hints, you should be able to find what you want ;)

Subprocess module is a good module to launch subprocesses. You can use it to call shell commands as this:

subprocess.call(["ls","-l"]);
#basic syntax
#subprocess.call(args, *)

You can see its documentation here.

If you have your script written in some .sh file or a long string, then you can use os.system module. It is fairly simple and easy to call:

import os
os.system("your command here")
# or
os.system('sh file.sh')

This command will run the script once, to completion, and block until it exits.

Your div variable is a string, not a DOM element object:

var div = '<div>top div</div>';

Strings don't have an appendChild method. Instead of creating a raw HTML string, create the div as a DOM element and append a text node, then append the input element:

var div = document.createElement('div');
div.appendChild(document.createTextNode('top div'));

div.appendChild(element);

As for Apache running on Ubuntu, the solution was to check error log, which showed that the error was related with folder and file permission.

First, check Apache error log

nano /var/log/apache2/error.log

Then set folder permission to be executable

sudo chmod 755 /var/www/html/

Also set file permission to be readable

sudo chmod 644 /var/www/html/.htaccess

Given:

A_1 = [10 200 7 150]';
A_2 = [0.001 0.450 0.007 0.200]';

(As others have already pointed out) There are tools to simply compute correlation, most obviously corr:

corr(A_1, A_2);  %Returns 0.956766573975184  (Requires stats toolbox)

You can also use base Matlab's corrcoef function, like this:

M = corrcoef([A_1 A_2]):  %Returns [1 0.956766573975185; 0.956766573975185 1];
M(2,1);  %Returns 0.956766573975184 

Which is closely related to the cov function:

cov([condition(A_1) condition(A_2)]);

As you almost get to in your original question, you can scale and adjust the vectors yourself if you want, which gives a slightly better understanding of what is going on. First create a condition function which subtracts the mean, and divides by the standard deviation:

condition = @(x) (x-mean(x))./std(x);  %Function to subtract mean AND normalize standard deviation

Then the correlation appears to be (A_1 * A_2)/(A_1^2), like this:

(condition(A_1)' * condition(A_2)) / sum(condition(A_1).^2);  %Returns 0.956766573975185

By symmetry, this should also work

(condition(A_1)' * condition(A_2)) / sum(condition(A_2).^2); %Returns 0.956766573975185

And it does.

I believe, but don't have the energy to confirm right now, that the same math can be used to compute correlation and cross correlation terms when dealing with multi-dimensiotnal inputs, so long as care is taken when handling the dimensions and orientations of the input arrays.

One difficulty is that the text, or description has line feeds. My clumsy kludge, to get it in something more tabular, is to add an HTML literal to the SELECT clause, copy and paste everything to notepad, save with an html extension, open in a browser, then copy and paste to a spreadsheet. example

SELECT obj.NAME AS TBL,trg.name,sm.definition,'<br>'
FROM SYS.OBJECTS obj
LEFT JOIN (SELECT trg1.object_id,trg1.parent_object_id,trg1.name FROM sys.objects trg1 WHERE trg1.type='tr' AND trg1.name like 'update%') trg
 ON obj.object_id=trg.parent_object_id
LEFT JOIN (SELECT sm1.object_id,sm1.definition FROM sys.sql_modules sm1 where sm1.definition like '%suser_sname()%') sm ON trg.object_id=sm.object_id
WHERE obj.type='u'
ORDER BY obj.name;

you may still need to fool around with tabs to get the description into one field, but at least it'll be on one line, which I find very helpful.

If there is no selection, you can use the properties .selectionStart or .selectionEnd (with no selection they're equal).

var cursorPosition = $('#myTextarea').prop("selectionStart");

Note that this is not supported in older browsers, most notably IE8-. There you'll have to work with text ranges, but it's a complete frustration.

I believe there is a library somewhere which is dedicated to getting and setting selections/cursor positions in input elements, though. I can't recall its name, but there seem to be dozens on articles about this subject.

nice one line alternative

element.addEventListener('dragstart',(evt) => onDragStart(param1, param2, param3, evt));

function onDragStart(param1, param2, param3, evt) {

 //some action...

}

You mean fast enumeration? You question is very unclear.

A normal for loop would look a bit like this:

unsigned int i, cnt = [someArray count];
for(i = 0; i < cnt; i++)
{ 
   // do loop stuff
   id someObject = [someArray objectAtIndex:i];
}

And a loop with fast enumeration, which is optimized by the compiler, would look like this:

for(id someObject in someArray)
{
   // do stuff with object
}

Keep in mind that you cannot change the array you are using in fast enumeration, thus no deleting nor adding when using fast enumeration

Using base graphics, we can use at = to control box position , combined with boxwex = for the width of the boxes. The 1st boxplot statement creates a blank plot. Then add the 2 traces in the following two statements.

Note that in the following, we use df[,-1] to exclude the 1st (id) column from the values to plot. With different data frames, it may be necessary to change this to subset for whichever columns contain the data you want to plot.

boxplot(df[,-1], boxfill = NA, border = NA) #invisible boxes - only axes and plot area
boxplot(df[df$id=="Good", -1], xaxt = "n", add = TRUE, boxfill="red", 
  boxwex=0.25, at = 1:ncol(df[,-1]) - 0.15) #shift these left by -0.15
boxplot(df[df$id=="Bad", -1], xaxt = "n", add = TRUE, boxfill="blue", 
  boxwex=0.25, at = 1:ncol(df[,-1]) + 0.15) #shift to the right by +0.15

Some dummy data:

df <- data.frame(
  id = c(rep("Good",200), rep("Bad", 200)),
  F1 = c(rnorm(200,10,2), rnorm(200,8,1)),
  F2 = c(rnorm(200,7,1),  rnorm(200,6,1)),
  F3 = c(rnorm(200,6,2),  rnorm(200,9,3)),
  F4 = c(rnorm(200,12,3), rnorm(200,8,2)))

I think I found a simpler solution, only this uses a subclass of ViewPager instead of (its parent) ScrollView.

UPDATE 2013-07-16: I added an override for onTouchEvent as well. It could possibly help with the issues mentioned in the comments, although YMMV.

public class UninterceptableViewPager extends ViewPager {

    public UninterceptableViewPager(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent ev) {
        boolean ret = super.onInterceptTouchEvent(ev);
        if (ret)
            getParent().requestDisallowInterceptTouchEvent(true);
        return ret;
    }

    @Override
    public boolean onTouchEvent(MotionEvent ev) {
        boolean ret = super.onTouchEvent(ev);
        if (ret)
            getParent().requestDisallowInterceptTouchEvent(true);
        return ret;
    }
}

This is similar to the technique used in android.widget.Gallery's onScroll(). It is further explained by the Google I/O 2013 presentation Writing Custom Views for Android.

Update 2013-12-10: A similar approach is also described in a post from Kirill Grouchnikov about the (then) Android Market app.

I think that R is reading the '\' in the string as an escape character. For example \n creates a new line within a string, \t creates a new tab within the string.

'\' will work because R will recognize this as a normal backslash.

Depending on what you want the file to contain:

• touch /path/to/file for an empty file

• somecommand > /path/to/file for a file containing the output of some command.

    eg: grep --help > randomtext.txt
        echo "This is some text" > randomtext.txt
  

• nano /path/to/file or vi /path/to/file (or any other editor emacs,gedit etc)
  It either opens the existing one for editing or creates & opens the empty file to enter, if it doesn't exist

Create the file using cat

$ cat > myfile.txt

Now, just type whatever you want in the file:

Hello World!

CTRL-D to save and exit

There are several possible solutions:

Create an empty file

touch file

>file

echo -n > file

printf '' > file

The echo version will work only if your version of echo supports the -n switch to suppress newlines. This is a non-standard addition. The other examples will all work in a POSIX shell.

Create a file containing a newline and nothing else

echo '' > file

printf '\n' > file

This is a valid "text file" because it ends in a newline.

Write text into a file

"$EDITOR" file

echo 'text' > file

cat > file <<END \
text
END

printf 'text\n' > file

These are equivalent. The $EDITOR command assumes that you have an interactive text editor defined in the EDITOR environment variable and that you interactively enter equivalent text. The cat version presumes a literal newline after the \ and after each other line. Other than that these will all work in a POSIX shell.

Of course there are many other methods of writing and creating files, too.

You can use NSNumberFormatter().numberFromString(yourNumberString). It's great because it returns an an optional that you can then test with if let to determine if the conversion was successful. eg.

var myString = "\(10)"
if let myNumber = NSNumberFormatter().numberFromString(myString) {
    var myInt = myNumber.integerValue
    // do what you need to do with myInt
} else {
    // what ever error code you need to write
}

Swift 5

var myString = "\(10)"
if let myNumber = NumberFormatter().number(from: myString) {
    var myInt = myNumber.intValue
    // do what you need to do with myInt
  } else {
    // what ever error code you need to write
  }

to get every unique value from your customer table, use

As a concept, the head is the latest revision in a branch. If you have more than one head per named branch you probably created it when doing local commits without merging, effectively creating an unnamed branch.

To have a "clean" repository, you should have one head per named branch and always merge to a named branch after you worked locally.

This is also true for Mercurial.

When entered as the reference of a Named range, it refers to range on the sheet the named range is used on.

For example, create a named range MyName refering to =SUM(!B1:!K1)

Place a formula on Sheet1 =MyName. This will sum Sheet1!B1:K1

Now place the same formula (=MyName) on Sheet2. That formula will sum Sheet2!B1:K1

Note: (as pnuts commented) this and the regular SheetName!B1:K1 format are relative, so reference different cells as the =MyName formula is entered into different cells.

Try running task manager to determine if your program is still running.

If it is running then stop it and run it again. the [Error] ld returned 1 exit status will not come back

you can use this solution:

items = { 'a', 'b' }
for k,v in pairs(items) do 
 if v == 'a' then 
  --do something
 else 
  --do something
 end
end

or

items = {'a', 'b'}
for k,v in pairs(items) do 
  while v do
    if v == 'a' then 
      return found
    else 
      break
    end
  end 
 end 
return nothing

For those deploying a docker image and using a locale that isn't shown in the locale -a command, add this line to your Dockerfile
RUN apt-get install -y locales

This should add all locales to your image, I used de_DE which is not part of AWS default Ubuntu server.

I don't know what you are comparing to.

But a super simple way to have a border look inset when compared to other non-bordered items is to add a border: ?px solid transparent; to whatever items do not have a border.

It will make the bordered item look inset.

If @Region is not a null value (lets say @Region = 'South') it will not return rows where the Region field is null, regardless of the value of ANSI_NULLS.

ANSI_NULLS will only make a difference when the value of @Region is null, i.e. when your first query essentially becomes the second one.

In that case, ANSI_NULLS ON will not return any rows (because null = null will yield an unknown boolean value (a.k.a. null)) and ANSI_NULLS OFF will return any rows where the Region field is null (because null = null will yield true)

There are no keys in JavaScript arrays. Use objects for that purpose.

var obj = {};

$.getJSON("displayjson.php",function (data) {
    $.each(data.news, function (i, news) {
        obj[news.title] = news.link;
    });                      
});

// later:
$.each(obj, function (index, value) {
    alert( index + ' : ' + value );
});

In JavaScript, objects fulfill the role of associative arrays. Be aware that objects do not have a defined "sort order" when iterating them (see below).

However, In your case it is not really clear to me why you transfer data from the original object (data.news) at all. Why do you not simply pass a reference to that object around?

You can combine objects and arrays to achieve predictable iteration and key/value behavior:

var arr = [];

$.getJSON("displayjson.php",function (data) {
    $.each(data.news, function (i, news) {
        arr.push({
            title: news.title, 
            link:  news.link
        });
    });                      
});

// later:
$.each(arr, function (index, value) {
    alert( value.title + ' : ' + value.link );
});

Of course, to each their own, but I think the block below is pretty solid. I believe this involves the "best" way to find a directory, and the "best" way to call another bash script:

scriptdir=`dirname "$BASH_SOURCE"`
source $scriptdir/incl.sh

echo "The main script"

So this may be the "best" way to include other scripts. This is based off another "best" answer that tells a bash script where it is stored

The current HTML5 draft specification does not specify which video formats browsers should support in the video tag. User agents are free to support any video formats they feel are appropriate.

http://en.wikipedia.org/wiki/HTML5_video

Usually what you choose will depend on which methods you need access to. In general - IEnumerable<> (MSDN: http://msdn.microsoft.com/en-us/library/system.collections.ienumerable.aspx) for a list of objects that only needs to be iterated through, ICollection<> (MSDN: http://msdn.microsoft.com/en-us/library/92t2ye13.aspx) for a list of objects that needs to be iterated through and modified, List<> for a list of objects that needs to be iterated through, modified, sorted, etc (See here for a full list: http://msdn.microsoft.com/en-us/library/6sh2ey19.aspx).

From a more specific standpoint, lazy loading comes in to play with choosing the type. By default, navigation properties in Entity Framework come with change tracking and are proxies. In order for the dynamic proxy to be created as a navigation property, the virtual type must implement ICollection.

A navigation property that represents the "many" end of a relationship must return a type that implements ICollection, where T is the type of the object at the other end of the relationship. -Requirements for Creating POCO Proxies^MSDN

I have a TypeScript file called "server.ts", The following npm scripts configures Nodemon and npm to start my app and monitor for any changes on TypeScript files:

"start": "nodemon -e ts  --exec \"npm run myapp\"",
"myapp": "tsc -p . && node server.js",

I already have Nodemon on dependencies. When I run npm start, it will ask Nodemon to monitor its files using the -e switch and then it calls the myapp npm script which is a simple combination of transpiling the typescript files and then starting the resulting server.js. When I change the TypeScript file, because of -e switch the same cycle happens and new .js files will be generated and executed.

Well, take a look, this works, If you have problems please tell me:

If you normalize your data first, then you can avoid all the very complex regular expressions required to validate phone numbers. From my experience, complicated regex patterns can have two unwanted side effects: (1) they can have unexpected behavior that would be a pain to debug later, and (2) they can be slower than simpler regex patterns, which may become noticeable when you are executing regex in a loop.

By keeping your regular expressions as simple as possible, you reduce these risks and your code will be easier for others to follow, partly because it will be more predictable. To use your phone number example, first we can normalize the value by stripping out all non-digits like this:

value = $.trim(value).replace(/\D/g, '');

Now your regex pattern for a US phone number (or any other locale) can be much simpler:

/^1?\d{10}$/

Not only is the regular expression much simpler, it is also easier to follow what's going on: a value optionally leading with number one (US country code) followed by ten digits. If you want to format the validated value to make it look pretty, then you can use this slightly longer regex pattern:

/^1?(\d{3})(\d{3})(\d{4})$/

This means an optional leading number one followed by three digits, another three digits, and ending with four digits. With each group of numbers memorized, you can output it any way you want. Here's a codepen using jQuery Validation to illustrate this for two locales (Singapore and US):

http://codepen.io/thdoan/pen/MaMqvZ

/*$mpdf = new mPDF('',    // mode - default ''
 '',    // format - A4, for example, default ''
 0,     // font size - default 0
 '',    // default font family
 15,    // margin_left
 15,    // margin right
 16,     // margin top
 16,    // margin bottom
 9,     // margin header
 9,     // margin footer
 'L');  // L - landscape, P - portrait*/

Since Ruby 2.5.0, Array ships with the prepend method (which is just an alias for the unshift method).

You can use us jquery function getJson :

$(function(){
    $.getJSON('/api/rest/abc', function(data) {
        console.log(data);
    });
});

that's the correct XOR swap algorithm

void xorSwap (int* x, int* y) {
   if (x != y) { //ensure that memory locations are different
      if (*x != *y) { //ensure that values are different
         *x ^= *y;
         *y ^= *x;
         *x ^= *y;
      }
   }
}

you have to ensure that memory locations are different and also that the actual values are different because A XOR A = 0

Create a class that describes the concept you're actually modeling and use that. It can just store two Set<Long> and provide accessors for them, but it should be named to indicate what exactly each of those sets is and why they're grouped together.

In Solaris OS I used this command:

$ who am i     # Remember to use it with space.

On Linux- Someone already answered this in comments.

$ whoami       # Without space

You should be using the thread pool (or async delgates, which in turn use the thread pool) so that the system can decide how many threads should run.

You could use SysInternal's PsExec.

The only way to add headers to a request from inside a browser is use the XmlHttpRequest setRequestHeader method.

Using this with "GET" request will download the resource. The trick then is to access the resource in the intended way. Ostensibly you should be able to allow the GET response to be cacheable for a short period, hence navigation to a new URL or the creation of an IMG tag with a src url should use the cached response from the previous "GET". However that is quite likely to fail especially in IE which can be a bit of a law unto itself where the cache is concerned.

Ultimately I agree with Mehrdad, use of query string is easiest and most reliable method.

Another quirky alternative is use an XHR to make a request to a URL that indicates your intent to access a resource. It could respond with a session cookie which will be carried by the subsequent request for the image or link.

The filename looks like a temporary table created by a query in MySQL. These files are often very short-lived, they're created during one specific query and cleaned up immediately afterwards.

Yet they can get very large, depending on the amount of data the query needs to process in a temp table. Or you may have multiple concurrent queries creating temp tables, and if enough of these queries run at the same time, they can exhaust disk space.

I do MySQL consulting, and I helped a customer who had intermittent disk full errors on his root partition, even though every time he looked, he had about 6GB free. After we examined his query logs, we discovered that he sometimes had four or more queries running concurrently, each creating a 1.5GB temp table in /tmp, which was on his root partition. Boom!

Solutions I gave him:

• Increase the MySQL config variables tmp_table_size and max_heap_table_size so MySQL can create really large temp tables in memory. But it's not a good idea to allow MySQL to create 1.5GB temp tables in memory, because there's no way to limit how many of these are created concurrently. You can exhaust your memory pretty quickly this way.

• Set the MySQL config variable tmpdir to a directory on another disk partition with more space.

• Figure out which of your queries is creating such big temp tables, and optimize the query. For example, use indexes to help that query reduce its scan to a smaller slice of the table. Or else archive some of the data in the tale so the query doesn't have so many rows to scan.

You can try this ! This should work on windows machines.

for /F "usebackq tokens=1,2,3 delims=-" %%I IN (`echo %date%`) do echo "%%I" "%%J" "%%K"

Adding placeholder attributes from code-behind:

txtFilterTerm.Attributes.Add("placeholder", "Filter" + Filter.Name);

Or

Necroing this question but there's an explanation that no-one seems to have considered.

STATISTICS - Statistics are not available or misleading

If all of the following are true:

1. The columns feedid and feedDate are likely to be highly correlated (e.g. a feed id is more specific than a feed date and the date parameter is redundant information).
2. There is no index with both columns as sequential columns.
3. There are no manually created statistics covering both these columns.

Then sql server may be incorrectly assuming that the columns are uncorrelated, leading to lower than expected cardinality estimates for applying both restrictions and a poor execution plan being selected. The fix in this case would be to create a statistics object linking the two columns, which is not an expensive operation.

Enums in TypeScript 0.9 are string+number based. You should not need type assertion for simple conversions:

enum Color{
    Red, Green
}

// To String
 var green: string = Color[Color.Green];

// To Enum / number
var color : Color = Color[green];

Try it online

I have documention about this and other Enum patterns in my OSS book : https://basarat.gitbook.io/typescript/type-system/enums

System.Environment has WorkingSet- a 64-bit signed integer containing the number of bytes of physical memory mapped to the process context.

If you want a lot of details there is System.Diagnostics.PerformanceCounter, but it will be a bit more effort to setup.

I see 2 easy options:

• multiple background with a translucent single gradient over image
• huge inset shadow

gradient option:

html {
  min-height:100%;
  background:linear-gradient(0deg, rgba(255, 0, 150, 0.3), rgba(255, 0, 150, 0.3)), url(http://lorempixel.com/800/600/nature/2);
  background-size:cover;
}

shadow option:

html {
  min-height:100%;
  background:url(http://lorempixel.com/800/600/nature/2);
  background-size:cover;
  box-shadow:inset 0 0 0 2000px rgba(255, 0, 150, 0.3);
}

an old codepen of mine with few examples

a third option

• with background-blen-mode :

  The background-blend-mode CSS property sets how an element's background images should blend with each other and with the element's background color.

html {
  min-height:100%;
  background:url(http://lorempixel.com/800/600/nature/2) rgba(255, 0, 150, 0.3);
  background-size:cover;
  background-blend-mode: multiply;

The best way is to simply reset the password by connecting with a domain/local admin (so you may need help from your system administrators), but this only works if SQL Server was set up to allow local admins (these are now left off the default admin group during setup).

If you can't use this or other existing methods to recover / reset the SA password, some of which are explained here:

• Disaster Recovery: What to do when the SA account password is lost in SQL Server 2005
• Is there a way I can retrieve sa password in sql server 2005
• How to recover SA password on Microsoft SQL Server 2008 R2

Then you could always backup your important databases, uninstall SQL Server, and install a fresh instance.

You can also search for less scrupulous ways to do it (e.g. there are password crackers that I am not enthusiastic about sharing).

As an aside, the login properties for sa would never say Windows Authentication. This is by design as this is a SQL Authentication account. This does not mean that Windows Authentication is disabled at the instance level (in fact it is not possible to do so), it just doesn't apply for a SQL auth account.

I wrote a tip on using PSExec to connect to an instance using the NT AUTHORITY\SYSTEM account (which works < SQL Server 2012), and a follow-up that shows how to hack the SqlWriter service (which can work on more modern versions):

• Recover access to a SQL Server instance
• More on Recovering Access to a SQL Server Instance

And some other resources:

• Connect to SQL Server When System Administrators Are Locked Out

• Leveraging Service SIDs to Logon to SQL Server Instances with Sysadmin Privileges

For clear all options en Important en FOR : remove(0) - Important: 0

} 

Taking DWins example.

What I often do, particularly when I use many, many different plots with the same colours or size information, is I store them in variables I otherwise never use. This helps me keep my code a little cleaner AND I can change it "globally".

E.g.

clab = 1.5
cmain = 2
caxis = 1.2

plot(1, 1 ,xlab="x axis", ylab="y axis",  pch=19,
           col.lab="red", cex.lab=clab,    
           col="green", main = "Testing scatterplots", cex.main =cmain, cex.axis=caxis) 

You can also write a function, doing something similar. But for a quick shot this is ideal. You can also store that kind of information in an extra script, so you don't have a messy plot script:

which you then call with setwd("") source("plotcolours.r")

in a file say called plotcolours.r you then store all the e.g. colour or size variables

clab = 1.5
cmain = 2
caxis = 1.2 

for colours could use

darkred<-rgb(113,28,47,maxColorValue=255)

as your variable 'darkred' now has the colour information stored, you can access it in your actual plotting script.

plot(1,1,col=darkred) 

You can pass an array as the first AutoFilter argument and use the xlFilterValues operator.

This will display PDF, DOC and DOCX filetypes.

Criteria1:=Array(".pdf", ".doc", ".docx"), Operator:=xlFilterValues

I like to remove missing values from a list like this:

list_no_nan = [x for x in list_with_nan if pd.notnull(x)]

fgets would work for you. here is very good documentation on this :-
http://www.cplusplus.com/reference/cstdio/fgets/

If you don't want to use fgets, following method will work for you :-

int readline(FILE *f, char *buffer, size_t len)
{
   char c; 
   int i;

   memset(buffer, 0, len);

   for (i = 0; i < len; i++)
   {   
      int c = fgetc(f); 

      if (!feof(f)) 
      {   
         if (c == '\r')
            buffer[i] = 0;
         else if (c == '\n')
         {   
            buffer[i] = 0;

            return i+1;
         }   
         else
            buffer[i] = c; 
      }   
      else
      {   
         //fprintf(stderr, "read_line(): recv returned %d\n", c);
         return -1; 
      }   
   }   

   return -1; 
}

(i === 0 ? "true" : "false")

You might want to use helper library like http://momentjs.com/ which wraps the native javascript date object for easier manipulations

Then you can do things like:

var day = moment("12-25-1995", "MM-DD-YYYY");

or

var day = moment("25/12/1995", "DD/MM/YYYY");

then operate on the date

day.add('days', 7)

and to get the native javascript date

day.toDate();

I just had a same issue of none of my console message showing. It was simply because I was using the new Edge (Chromium based) browser on Windows 10. It does not show my console messages whereas Chrome does. I guessed it was an issue with Edge because I had another odd issue with Edge because it treated strings with single quotes and double quotes differently.

Don't know for sure, but it sounds like it is still submitting. I quick solution would be to change your (guessing at your code here):

<input type="submit" value="Submit" onclick="checkform()">

to a button:

<input type="button" value="Submit" onclick="checkform()">

That way your form still gets submitted (from the else part of your checkform()) and it shouldn't be reloading the page.

There are other, perhaps better, ways of handling it but this works in the mean time.

Why not go even simpler with either one of these options:

$("#box").html('<div id="myid" style="display:block; float:left;width:'+width+'px; height:'+height+'px; margin-top:'+positionY+'px;margin-left:'+positionX+'px;border:1px dashed #CCCCCC;"></div>');

Or, if you want to append it to existing content:

$("#box").append('<div id="myid" style="display:block; float:left;width:'+width+'px; height:'+height+'px; margin-top:'+positionY+'px;margin-left:'+positionX+'px;border:1px dashed #CCCCCC;"></div>');

Note: I put the id="myid" right into the HTML string rather than using separate code to set it.

Both the .html() and .append() jQuery methods can take a string of HTML so there's no need to use a separate step for creating the objects.

Here is my solution

-- Create the maximum number of words we want to pick (indexes in n)
with recursive n(i) as (
    select
        1 i
    union all
    select i+1 from n where i < 1000
)
select distinct
    s.id,
    s.oaddress,
    -- n.i,
    -- use the index to pick the nth word, the last words will always repeat. Remove the duplicates with distinct
    if(instr(reverse(trim(substring_index(s.oaddress,' ',n.i))),' ') > 0,
        reverse(substr(reverse(trim(substring_index(s.oaddress,' ',n.i))),1,
            instr(reverse(trim(substring_index(s.oaddress,' ',n.i))),' '))),
        trim(substring_index(s.oaddress,' ',n.i))) oth
from 
    app_schools s,
    n

If you're working with an x64 server, keep in mind that there are different ODBC settings for x86 and x64 applications. The "Data Sources (ODBC)" tool in the Administrative Tools list takes you to the x64 version. To view/edit the x86 ODBC settings, you'll need to run that version of the tool manually:

%windir%\SysWOW64\odbcad32.exe (%windir% is usually C:\Windows)

When your app runs as x64, it will use the x64 data sources, and when it runs as x86, it will use those data sources instead.

We need to add host security certificate to php.ini file. For local developement enviroment we can add cacert.pem in your local php.ini.

do phpinfo(); and file your php.ini path open and add uncomment ;curl.capath

curl.capath=path_of_your_cacert.pem

Assuming the connection is established and is available in global scope;

//Check if a value exists in a table
function record_exists ($table, $column, $value) {
    global $connection;
    $query = "SELECT * FROM {$table} WHERE {$column} = {$value}";
    $result = mysql_query ( $query, $connection );
    if ( mysql_num_rows ( $result ) ) {
        return TRUE;
    } else {
        return FALSE;
    }
}

Usage: Assuming that the value to be checked is stored in the variable $username;

if (record_exists ( 'employee', 'username', $username )){
    echo "Username is not available. Try something else.";
} else {
    echo "Username is available";
}

My example comment to @qubyte above got chopped, so here's something that's easier to read...

The method @surjikal described above works for branch commits, but it didn't work for a tree commit I was trying include.

The archive mode also works for commits. For example, fetch @ a2fbf83

yarn:

yarn add  https://github.com/github/fetch/archive/a2fbf834773b8dc20eef83bb53d081863d3fc87f.tar.gz

format:

I spotted half of the problem: I can't use the 'indexer' notation to objects (my_object[0]). Is there a way to bypass it?

No; an object literal, as the name implies, is an object, and not an array, so you cannot simply retrieve a property based on an index, since there is no specific order of their properties. The only way to retrieve their values is by using the specific name:

var someVar = options.filters.firstName; //Returns 'abc'

Or by iterating over them using the for ... in loop:

for(var p in options.filters) {
    var someVar = options.filters[p]; //Returns the property being iterated
}

What you describe is the correct way to handle this.

You said that you want to stay in the GUI. You can usually set the execute bit through the file properties menu. You could also learn how to create a custom action for the context menu to do this for you if you're so inclined. This depends on your desktop environment of course.

If you use a more advanced editor, you can script the action to happen when the file is saved. For example (I'm only really familiar with vim), you could add this to your .vimrc to make any new file that starts with "#!/*/bin/*" executable.

au BufWritePost * if getline(1) =~ "^#!" | if getline(1) =~ "/bin/" | silent !chmod +x <afile> | endif | endif

This is specific for each site. So if you type that once, you will only get through that site and all other sites will need a similar type-through.

It is also remembered for that site and you have to click on the padlock to reset it (so you can type it again):

Needless to say use of this "feature" is a bad idea and is unsafe - hence the name.

You should find out why the site is showing the error and/or stop using it until they fix it. HSTS specifically adds protections for bad certs to prevent you clicking through them. The fact it's needed suggests there is something wrong with the https connection - like the site or your connection to it has been hacked.

The chrome developers also do change this periodically. They changed it recently from badidea to thisisunsafe so everyone using badidea, suddenly stopped being able to use it. You should not depend on it. As Steffen pointed out in the comments below, it is available in the code should it change again though they now base64 encode it to make it more obscure. The last time they changed they put this comment in the commit:

Rotate the interstitial bypass keyword

The security interstitial bypass keyword hasn't changed in two years and awareness of the bypass has been increased in blogs and social media. Rotate the keyword to help prevent misuse.

I think the message from the Chrome team is clear - you should not use it. It would not surprise me if they removed it completely in future.

If you are using this when using a self-signed certificate for local testing then why not just add your self-signed certificate certificate to your computer's certificate store so you get a green padlock and do not have to type this? Note Chrome insists on a SAN field in certificates now so if just using the old subject field then even adding it to the certificate store will not result in a green padlock.

If you leave the certificate untrusted then certain things do not work. Caching for example is completely ignored for untrusted certificates. As is HTTP/2 Push.

HTTPS is here to stay and we need to get used to using it properly - and not bypassing the warnings with a hack that is liable to change and doesn't work the same as a full HTTPS solution.

Try doing this, using firefox as fake user agent (moreover, it's a good startup script for web scraping with the use of cookies):

    page.addheaders = [('User-agent', 'Mozilla/5.0')]
    print page.read()

The simplest way to install jq and test that it works is through brew and then using the simplest filter that merely formats the JSON

Install

brew is the easiest way to manage packages on a mac:

brew install jq

Need brew? Run the following command:

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Failing that: instructions to install and use are on https://brew.sh/

Test

The . filter takes its input and produces it unchanged as output. This is the identity operator. (quote the docs)

echo '{ "name":"John", "age":31, "city":"New York" }' | jq .

The result should appear like so in your terminal:

{
  "name": "John",
  "age": 31,
  "city": "New York"
}

At the risk of echoing every other answer, no, you cannot mix them in the same project.

That aside, if you just finished converting VB to C#, why would you write new code in VB?

You can update your Bitbucket credentials from the OSX Keychain.

Updating your cached credentials via the command line:

$ git credential-osxkeychain erase
host=bitbucket.org
protocol=https
[press return]

If it's successful, nothing will print out. To test that it works, try and clone a repository from Bitbucket. If you are prompted for a password, the keychain entry was deleted.

Short answer: You are calling a file/directory as a function instead of real function

Read on:

This kind of error happens when you import module thinking it as function and call it. So in python module is a .py file. Packages(directories) can also be considered as modules. Let's say I have a create.py file. In that file I have a function like this:

#inside create.py
def create():
  pass

Now, in another code file if I do like this:

#inside main.py file
import create
create() #here create refers to create.py , so create.create() would work here

It gives this error as am calling the create.py file as a function. so I gotta do this:

from create import create
create() #now it works.

Hope that helps! Happy Coding!

java.util.UUID : toString() method

Consider a skewed binary tree with 3 nodes as 7, 3, 2. For any operation like for searching 2, we have to traverse 3 nodes, for deleting 2 also, we have to traverse 3 nodes and for for inserting 1 also, we have to traverse 3 nodes. So, binary tree has worst case complexity of O(n).

The accepted answer is faulty, since the contents from the initial user folder are not moved using it. I am going to add another answer to correct it:

sudo usermod -d /newhome/username -m username

You don't need to create the folder with username and this will also move your files from the initial user folder to /newhome/username folder.

For plaintext email using JavaScript, you may also use \r with encodeURIComponent().

For example, this message:

hello\rthis answer is now well formated\rand it contains good knowleadge\rthat is why I am up voting

URI Encoded, results in:

hello%0Dthis%20answer%20is%20now%20well%20formated%0Dand%20it%20contains%20good%20knowleadge%0Dthat%20is%20why%20I%20am%20up%20voting

And, using the href:

mailto:[email protected]?body=hello%0Dthis%20answer%20is%20now%20well%20formated%0Dand%20it%20contains%20good%20knowleadge%0Dthat%20is%20why%20I%20am%20up%20voting

Will result in the following email body text:

hello
this answer is now well formated
and it contains good knowleadge
that is why I am up voting

To support IE11 with auto-placement, I converted grid to table layout every time I used the grid layout in 1 dimension only. I also used margin instead of grid-gap.

The result is the same, see how you can do it here https://jsfiddle.net/hp95z6v1/3/

This class was compiled with a JDK more recent than the one used for execution.

The easiest is to install a more recent JRE on the computer where you execute the program. If you think you installed a recent one, check the JAVA_HOME and PATH environment variables.

Version 49 is java 1.5. That means the class was compiled with (or for) a JDK which is yet old. You probably tried to execute the class with JDK 1.4. You really should use one more recent (1.6 or 1.7, see java version history).

On some mobiles like mine (MIUI Redmi 3) you can just add specific Application on list where application doesnt stop when you terminate applactions in Task Manager (It will stop but it will start again)

Just go to Settings>PermissionsAutostart

Java will not throw an exception if you divide by float zero. It will detect a run-time error only if you divide by integer zero not double zero.

If you divide by 0.0, the result will be INFINITY.

In Android Studio version 3.0 or more I have used bellow like :

1. Create libs to the app directory if not exist folder like

• Set Project view in upper left corner
• Go to project
• Go to app
• click on apps->New->Directory
• name the folder libs
• paste the jar to the libs folder
• directory will look like bellow image

2. In build.gradle add these lines

   // Add this line if was not added before.
   implementation fileTree(dir: 'libs', include: ['*.jar'])
   
   implementation files('libs/com.ibm.icu_3.4.4.1.jar')
   

You can also get it by

string(//bookstore/book[1]/title/@lang)    
string(//bookstore/book[2]/title/@lang)

although if you are using XMLDOM with JavaScript you can code something like

var n1 = uXmlDoc.selectSingleNode("//bookstore/book[1]/title/@lang");

and n1.text will give you the value "eng"

You could try the following in your root directory:

// initialize git for your project, add the changes and perform a commit

git init
git add .
git commit -m "first commit"

// create heroku app and push to heroku

heroku create
git push heroku master

Not sure where you are in the process. You also don't need github to deploy on heroku, just git. Hope this helps!

I use setInterval to wait for the content loaded. I hope this can help you to solve that problem.

var $audio = $('#audio');
var src = $audio.attr('src');
var a;
a = window.setInterval(function(){
    src = $audio.attr('src');
    if(src != undefined){
        window.clearInterval(a);
        $('audio').mediaelementplayer({
            audioWidth: '100%'
        });
    }
}, 0);

After this, From File Menu select Save Book ,from next menu select "Excel 97-2003 Add-In (*.xla)

It will save as Excel Add-In. that will be available till the Ms.Office Installation to that machine.

Now Open any Excel File in any Cell type =WordNum(<your numeric value or cell reference>)

you will see a Words equivalent of the numeric value.

This code worked for me.

After clicking on the link, it will ask you to choose the contact to share a message.

<a href="https://api.whatsapp.com/send?text=enter message here">Click here to share on Whatsapp</a>

You can add target="_blank" attribute to open it in a new window or tab.

I don't think the phone number is needed when someone wants to share a particular message or article.

If you want to remove F0 from the whole string then the replaceAll() method works for you.

const str = 'F0123F0456F0'.replaceAll('F0', '');
console.log(str);

I broadly agree with @Ralph Buchfelder, but here's some amplification of this, by experiment when trying to replicate a system with several subdomains (such as example.com, fr.example.com, de.example.com) on my local machine (OS X / Apache / Chrome|Firefox).

I've edited /etc/hosts to point some imaginary subdomains at 127.0.0.1:

127.0.0.1 localexample.com
127.0.0.1 fr.localexample.com
127.0.0.1 de.localexample.com

If I am working on fr.localexample.com and I leave the domain parameter out, the cookie is stored correctly for fr.localexample.com, but is not visible in the other subdomains.

If I use a domain of ".localexample.com", the cookie is stored correctly for fr.localexample.com, and is visible in other subdomains.

If I use a domain of "localexample.com", or when I was trying a domain of just "localexample" or "localhost", the cookie was not getting stored.

If I use a domain of "fr.localexample.com" or ".fr.localexample.com", the cookie is stored correctly for fr.localexample.com and is (correctly) invisible in other subdomains.

So the requirement that you need at least two dots in the domain appears to be correct, even though I can't see why it should be.

If anyone wants to try this out, here's some useful code:

<html>
<head>
<title>
Testing cookies
</title>
</head>
<body>
<?php
header('HTTP/1.0 200');
$domain = 'fr.localexample.com';    // Change this to the domain you want to test.
if (!empty($_GET['v'])) {
    $val = $_GET['v'];
    print "Setting cookie to $val<br/>";
    setcookie("mycookie", $val, time() + 48 * 3600, '/', $domain);
}
print "<pre>";
print "Cookie:<br/>";
var_dump($_COOKIE);
print "Server:<br/>";
var_dump($_SERVER);
print "</pre>";
?>
</body>
</html>

To convert an int ASCII value to character you can also use:

int asciiValue = 65;
char character = char(asciiValue);
cout << character; // output: A
cout << char(90); // output: Z

Imports System.IO
Public Class Form1
    Public line, counter As String
    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        counter += 1
        If TextBox1.Text = "" Then
            MsgBox("Enter a DNS address to ping")
        Else
            'line = ":start" + vbNewLine
            'line += "ping " + TextBox1.Text
            'MsgBox(line)
            Dim StreamToWrite As StreamWriter
            StreamToWrite = New StreamWriter("C:\Desktop\Ping" + counter + ".bat")
            StreamToWrite.Write(":start" + vbNewLine + _
                                "Ping -t " + TextBox1.Text)
            StreamToWrite.Close()
            Dim p As New System.Diagnostics.Process()
            p.StartInfo.FileName = "C:\Desktop\Ping" + counter + ".bat"
            p.Start()
        End If
    End Sub
End Class

This works as well

To increase security even more, You can have md5 encryption along with two different salt strings, one static salt defined in php file and then one more randomly generated unique salt for each password record.

Here is how you can generate salt, md5 string and store:

    $unique_salt_string = hash('md5', microtime()); 
    $password = hash('md5', $_POST['password'].'static_salt'.$unique_salt_string);
    $query = "INSERT INTO users (username,password,salt) VALUES('bob','".$password."', '".$unique_salt_string."');

Now you have a static salt, which is valid for all your passwords, that is stored in the .php file. Then, at registration execution, you generate a unique hash for that specific password.

This all ends up with: two passwords that are spelled exactly the same, will have two different hashes. The unique hash is stored in the database along with the current id. If someone grab the database, they will have every single unique salt for every specific password. But what they don't have is your static salt, which make things a lot harder for every "hacker" out there.

This is how you check the validity of your password on login.php for example:

     $user = //username input;
     $db_query = mysql_query("SELECT salt FROM users WHERE username='$user'");
     while($salt = mysql_fetch_array($db_query)) {
            $password = hash('md5',$_POST['userpassword'].'static_salt'.$salt[salt]);
}

This method is very powerful and secure. If you want to use sha512 encryption, just to put that inside the hash function instead of md5 in above code.

Some time ago I wrote simple Webcam Capture API which can be used for that. The project is available on Github.

Example code:

Webcam webcam = Webcam.getDefault();
webcam.open();
try {
  ImageIO.write(webcam.getImage(), "PNG", new File("test.png"));
} catch (IOException e) {
  e.printStackTrace();
} finally {
  webcam.close();
}

You could use Javascript:

// This is in the PHP file and sends a Javascript alert to the client
$message = "wrong answer";
echo "<script type='text/javascript'>alert('$message');</script>";

Just tell composer to use source if available:

composer update --prefer-source

Or:

composer install --prefer-source

Then you will get packages as cloned repositories instead of extracted tarballs, so you can make some changes and commit them back. Of course, assuming you have write/push permissions to the repository and Composer knows about project's repository.

Disclaimer: I think I may answered a little bit different question, but this was what I was looking for when I found this question, so I hope it will be useful to others as well.

If Composer does not know, where the project's repository is, or the project does not have proper composer.json, situation is a bit more complicated, but others answered such scenarios already.

sed "s/^[ \t]*//" -i youfile

Warning: this will overwrite the original file.

Or else you can use two arrays to implement queue data structure.

var temp_stack = new Array();
var stack = new Array();

temp_stack.push(1);
temp_stack.push(2);
temp_stack.push(3);

If I pop the elements now then the output will be 3,2,1. But we want FIFO structure so you can do the following.

stack.push(temp_stack.pop());
stack.push(temp_stack.pop());
stack.push(temp_stack.pop());

stack.pop(); //Pop out 1
stack.pop(); //Pop out 2
stack.pop(); //Pop out 3

1. SOAP Web Services are standard-based and supported by almost every software platform: They rely heavily in XML and have support for transactions, security, asynchronous messages and many other issues. It’s a pretty big and complicated standard, but covers almost every messaging situation. On the other side, RESTful services relies of HTTP protocol and verbs (GET, POST, PUT, DELETE) to interchange messages in any format, preferable JSON and XML. It’s a pretty simple and elegant architectural approach.
2. As in every topic in the Java World, there are several libraries to build/consume Web Services. In the SOAP Side you have the JAX-WS standard and Apache Axis, and in REST you can use Restlets or Spring REST Facilities among other libraries.

With question 3, this article states that RESTful Services are appropiate in this scenarios:

• If you have limited bandwidth
• If your operations are stateless: No information is preserved from one invocation to the next one, and each request is treated independently.
• If your clients require caching.

While SOAP is the way to go when:

• If you require asynchronous processing
• If you need formal contract/Interfaces
• In your service operations are stateful: For example, you store information/data on a request and use that stored data on the next one.

A complete pywin32 example using loop or subthread

After working on this on and off for a few days, here is the answer I would have wished to find, using pywin32 to keep it nice and self contained.

This is complete working code for one loop-based and one thread-based solution. It may work on both python 2 and 3, although I've only tested the latest version on 2.7 and Win7. The loop should be good for polling code, and the tread should work with more server-like code. It seems to work nicely with the waitress wsgi server that does not have a standard way to shut down gracefully.

I would also like to note that there seems to be loads of examples out there, like this that are almost useful, but in reality misleading, because they have cut and pasted other examples blindly. I could be wrong. but why create an event if you never wait for it?

That said I still feel I'm on somewhat shaky ground here, especially with regards to how clean the exit from the thread version is, but at least I believe there are nothing misleading here.

To run simply copy the code to a file and follow the instructions.

update:

Use a simple flag to terminate thread. The important bit is that "thread done" prints.
For a more elaborate example exiting from an uncooperative server thread see my post about the waitress wsgi server.

IntelliJ 13 Steps:

1. Code -> Reformat Code
2. Edit -> Macros -> Start Macro Recording
3. Code -> Reformat Code
4. File -> Save all
5. Edit -> Macros -> Stop Macro Recording
6. Name the macro (something like "formatted save")

Reference here

Benjamin Bannier's answer yields a pass-through when the median of distances from the median is 0, so I found this modified version a bit more helpful for cases as given in the example below.

def reject_outliers_2(data, m=2.):
    d = np.abs(data - np.median(data))
    mdev = np.median(d)
    s = d / (mdev if mdev else 1.)
    return data[s < m]

Example:

data_points = np.array([10, 10, 10, 17, 10, 10])
print(reject_outliers(data_points))
print(reject_outliers_2(data_points))

Gives:

[[10, 10, 10, 17, 10, 10]]  # 17 is not filtered
[10, 10, 10, 10, 10]  # 17 is filtered (it's distance, 7, is greater than m)

from pexpect import pxssh
s = pxssh.pxssh()
if not s.login ('localhost', 'myusername', 'mypassword'):
    print "SSH session failed on login."
    print str(s)
else:
    print "SSH session login successful"
    s.sendline ('ls -l')
    s.prompt()         # match the prompt
    print s.before     # print everything before the prompt.
    s.logout()

Well, I am quite surprised that the alternatives to this syntax have not been mentioned. Another common (but older) mechanism is to call a function that isn't defined and rely on the optimizer to compile-out the function call if your assertion is correct.

#define MY_COMPILETIME_ASSERT(test)              \
    do {                                         \
        extern void you_did_something_bad(void); \
        if (!(test))                             \
            you_did_something_bad(void);         \
    } while (0)

While this mechanism works (as long as optimizations are enabled) it has the downside of not reporting an error until you link, at which time it fails to find the definition for the function you_did_something_bad(). That's why kernel developers starting using tricks like the negative sized bit-field widths and the negative-sized arrays (the later of which stopped breaking builds in GCC 4.4).

In sympathy for the need for compile-time assertions, GCC 4.3 introduced the error function attribute that allows you to extend upon this older concept, but generate a compile-time error with a message of your choosing -- no more cryptic "negative sized array" error messages!

#define MAKE_SURE_THIS_IS_FIVE(number)                          \
    do {                                                        \
        extern void this_isnt_five(void) __attribute__((error(  \
                "I asked for five and you gave me " #number))); \
        if ((number) != 5)                                      \
            this_isnt_five();                                   \
    } while (0)

In fact, as of Linux 3.9, we now have a macro called compiletime_assert which uses this feature and most of the macros in bug.h have been updated accordingly. Still, this macro can't be used as an initializer. However, using by statement expressions (another GCC C-extension), you can!

#define ANY_NUMBER_BUT_FIVE(number)                           \
    ({                                                        \
        typeof(number) n = (number);                          \
        extern void this_number_is_five(void) __attribute__(( \
                error("I told you not to give me a five!"))); \
        if (n == 5)                                           \
            this_number_is_five();                            \
        n;                                                    \
    })

This macro will evaluate its parameter exactly once (in case it has side-effects) and create a compile-time error that says "I told you not to give me a five!" if the expression evaluates to five or is not a compile-time constant.

So why aren't we using this instead of negative-sized bit-fields? Alas, there are currently many restrictions of the use of statement expressions, including their use as constant initializers (for enum constants, bit-field width, etc.) even if the statement expression is completely constant its self (i.e., can be fully evaluated at compile-time and otherwise passes the __builtin_constant_p() test). Further, they cannot be used outside of a function body.

Hopefully, GCC will amend these shortcomings soon and allow constant statement expressions to be used as constant initializers. The challenge here is the language specification defining what is a legal constant expression. C++11 added the constexpr keyword for just this type or thing, but no counterpart exists in C11. While C11 did get static assertions, which will solve part of this problem, it wont solve all of these shortcomings. So I hope that gcc can make a constexpr functionality available as an extension via -std=gnuc99 & -std=gnuc11 or some such and allow its use on statement expressions et. al.

React native does not have the concept of global variables. It enforces modular scope strictly, in order to promote component modularity and reusability.

Sometimes, though, you need components to be aware of their environment. In this case it's very simple to define an Environment module which components can then call to get environment variables, for example:

environment.js

var _Environments = {
    production:  {BASE_URL: '', API_KEY: ''},
    staging:     {BASE_URL: '', API_KEY: ''},
    development: {BASE_URL: '', API_KEY: ''},
}

function getEnvironment() {
    // Insert logic here to get the current platform (e.g. staging, production, etc)
    var platform = getPlatform()

    // ...now return the correct environment
    return _Environments[platform]
}

var Environment = getEnvironment()
module.exports = Environment

my-component.js

var Environment = require('./environment.js')

...somewhere in your code...
var url = Environment.BASE_URL

This creates a singleton environment which can be accessed from anywhere inside the scope of your app. You have to explicitly require(...) the module from any components that use Environment variables, but that is a good thing.

In Ubuntu 18.04 the QtCreator examples and API docs missing, This is my way to solve this problem, should apply to almost every Ubuntu release.

For QtCreator and Examples and API Docs:

sudo apt install `apt-cache search 5-examples | grep qt | grep example | awk '{print $1 }' | xargs `

sudo apt install `apt-cache search 5-doc | grep "Qt 5 " | awk '{print $1}' | xargs`

sudo apt-get install build-essential qtcreator qt5-default

If something is also missing, then:

sudo apt install `apt-cache search qt | grep 5- | grep ^qt | awk '{print $1}' | xargs `

Hope to be helpful.

In React Native , This worked for me

name = "hi \n\ruser"
name.replace( /[\r\n]+/gm, ""); // hi user

Using the so called f strings:

answer = True
myvar = f"the answer is {answer}"

Then if I do

print(myvar)

I will get:

the answer is True

I like f strings because one does not have to worry about the order in which the variables will appear in the printed text, which helps in case one has multiple variables to be printed as strings.

Do check the man pages of your ping command before trying some of these examples out (always good practice anyway). For Ubuntu 16 (for example) the accepted answer doesn't work as the -n 3 fails (this isn't the count of packets anymore, -n denotes not converting the IP address to a hostname).

Following the request of the OP, a potential alternative function would be as follows:

function checkPing($ip){
    $ping = trim(`which ping`);
    $ll = exec($ping . '-n -c2 ' . $ip, $output, $retVar);
    if($retVar == 0){
        echo "The IP address, $ip, is alive";
        return true;
    } else {
        echo "The IP address, $ip, is dead";
        return false;
    }
}

For my issue, I had to zero out the log:

sudo bash -c ' > /Applications/XAMPP/xamppfiles/logs/php_error_log '

Will take you to the master branch.

git checkout master

To switch to other branches do (ignore the square brackets, it's just for emphasis purposes)

git checkout [the name of the branch you want to switch to]

To create a new branch use the -b like this (ignore the square brackets, it's just for emphasis purposes)

git checkout -b [the name of the branch you want to create]

As suggest by @TheMatrixRecoder took a bit of finding for me so maybe this will help someone else.

Unitick these options to prevent annoying automated formatting when you places a semicolon or hit return at the end of a line.

PendingIntent is basically an object that wraps another Intent object. Then it can be passed to a foreign application where you’re granting that app the right to perform the operation, i.e., execute the intent as if it were executed from your own app’s process (same permission and identity). For security reasons you should always pass explicit intents to a PendingIntent rather than being implicit.

 PendingIntent aPendingIntent = PendingIntent.getService(Context, 0, aIntent,
                    PendingIntent.FLAG_CANCEL_CURRENT);

For me the android:scaleType="centerCrop" did not resolve my problem. It actually expanded the image way more. So I tried with android:scaleType="fitXY" and It worked excellent.

Use NSJSONSerialization:

NSDictionary *dict;
NSData *dataFromDict = [NSJSONSerialization dataWithJSONObject:dict
                                                       options:NSJSONWritingPrettyPrinted
                                                         error:&error];

NSDictionary *dictFromData = [NSJSONSerialization JSONObjectWithData:dataFromDict
                                                             options:NSJSONReadingAllowFragments
                                                               error:&error];

The latest returns id, so its a good idea to check the returned object type after you cast (here i casted to NSDictionary).

Perhaps the easiest way would be to add an image, scale it, and set it to the JFrame/JPanel (in my case JPanel) but remember to "add" it to the container only after you've added the other children components.

    ImageIcon background=new ImageIcon("D:\\FeedbackSystem\\src\\images\\background.jpg");
    Image img=background.getImage();
    Image temp=img.getScaledInstance(500,600,Image.SCALE_SMOOTH);
    background=new ImageIcon(temp);
    JLabel back=new JLabel(background);
    back.setLayout(null);
    back.setBounds(0,0,500,600);

Try format function:

> xx = 100000000000
> xx
[1] 1e+11
> format(xx, scientific=F)
[1] "100000000000"

You have to use the SelectMany extension method or its equivalent syntax in pure LINQ.

(from model in list
 where model.application == "applicationname"
 from user in model.users
 where user.surname == "surname"
 select new { user, model }).ToList();

$ declare -a arr
$ arr=("a")
$ arr=("${arr[@]}" "new")
$ echo ${arr[@]}
a new
$ arr=("${arr[@]}" "newest")
$ echo ${arr[@]}
a new newest

SQLFiddle will let you test out your queries, while it doesn't explicitly correct syntax etc. per se it does let you play around with the script and will definitely let you know if things are working or not.

The approach I use is to start the "Visual Studio Command Prompt" which can be found in the Start menu. E.g. my visual studio 2010 Express install has a shortcute Visual Studio Command Prompt (2010) at Start Menu\Programs\Microsoft Visual Studio 2010\Visual Studio Tools.

This shortcut prepares an environment by calling a script vcvarsall.bat where the compiler, linker, etc. are setup from the right Visual Studio installation.

Alternatively, if you already have a prompt open, you can prepare the environment by calling a similar script:

:: For x86 (using the VS100COMNTOOLS env-var)
call "%VS100COMNTOOLS%"\..\..\VC\bin\vcvars32.bat

or

:: For amd64 (using the full path)
call C:\Program Files\Microsoft Visual Studio 10.0\VC\bin\amd64\vcvars64.bat

However:

Your output (with the '$' prompt) suggests that you are attempting to run CMake from a MSys shell. In that case it might be better to run CMake for MSys or MinGW, by explicitly specifying a makefile generator:

cmake -G"MSYS Makefiles"
cmake -G"MinGW Makefiles"

Run cmake --help to get a list of all possible generators.

Check out the node.js module list

• node-mysql — A node.js module implementing the MySQL protocol
• node-mysql2 — Yet another pure JS async driver. Pipelining, prepared statements.
• node-mysql-libmysqlclient — MySQL asynchronous bindings based on libmysqlclient

node-mysql looks simple enough:

var mysql      = require('mysql');
var connection = mysql.createConnection({
  host     : 'example.org',
  user     : 'bob',
  password : 'secret',
});

connection.connect(function(err) {
  // connected! (unless `err` is set)
});

Queries:

var post  = {id: 1, title: 'Hello MySQL'};
var query = connection.query('INSERT INTO posts SET ?', post, function(err, result) {
  // Neat!
});
console.log(query.sql); // INSERT INTO posts SET `id` = 1, `title` = 'Hello MySQL'

A delegate is a reference to a method. Whereas objects can easily be sent as parameters into methods, constructor or whatever, methods are a bit more tricky. But every once in a while you might feel the need to send a method as a parameter to another method, and that's when you'll need delegates.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace DelegateApp {

  /// <summary>
  /// A class to define a person
  /// </summary>
  public class Person {
    public string Name { get; set; }
    public int Age { get; set; }
  }

  class Program {
    //Our delegate
    public delegate bool FilterDelegate(Person p);

    static void Main(string[] args) {

      //Create 4 Person objects
      Person p1 = new Person() { Name = "John", Age = 41 };
      Person p2 = new Person() { Name = "Jane", Age = 69 };
      Person p3 = new Person() { Name = "Jake", Age = 12 };
      Person p4 = new Person() { Name = "Jessie", Age = 25 };

      //Create a list of Person objects and fill it
      List<Person> people = new List<Person>() { p1, p2, p3, p4 };

      //Invoke DisplayPeople using appropriate delegate
      DisplayPeople("Children:", people, IsChild);
      DisplayPeople("Adults:", people, IsAdult);
      DisplayPeople("Seniors:", people, IsSenior);

      Console.Read();
    }

    /// <summary>
    /// A method to filter out the people you need
    /// </summary>
    /// <param name="people">A list of people</param>
    /// <param name="filter">A filter</param>
    /// <returns>A filtered list</returns>
    static void DisplayPeople(string title, List<Person> people, FilterDelegate filter) {
      Console.WriteLine(title);

      foreach (Person p in people) {
        if (filter(p)) {
          Console.WriteLine("{0}, {1} years old", p.Name, p.Age);
        }
      }

      Console.Write("\n\n");
    }

    //==========FILTERS===================
    static bool IsChild(Person p) {
      return p.Age < 18;
    }

    static bool IsAdult(Person p) {
      return p.Age >= 18;
    }

    static bool IsSenior(Person p) {
      return p.Age >= 65;
    }
  }
}

Output:

Children:
Jake, 12 years old


Adults:
John, 41 years old
Jane, 69 years old
Jessie, 25 years old


Seniors:
Jane, 69 years old

I had a similar problem.

Setting width to "auto" worked fine for me but when the dialog contained a lot of text it made it span the full width of the page, ignoring the maxWidth setting.

Setting maxWidth on create works fine though:

$( ".selector" ).dialog({
  width: "auto",
  // maxWidth: 660, // This won't work
  create: function( event, ui ) {
    // Set maxWidth
    $(this).css("maxWidth", "660px");
  }
});

I suggest you to start from an existing solution and customize it to fit your needs, that's better than starting from scratch!

I was looking for the same thing and I fall on this open source solution, I hope it will help.

This might be not 100% related to the question, but on my search for an example of using multiprocessing with a queue this shows up first on google.

This is a basic example class that you can instantiate and put items in a queue and can wait until queue is finished. That's all I needed.

from multiprocessing import JoinableQueue
from multiprocessing.context import Process


class Renderer:
    queue = None

    def __init__(self, nb_workers=2):
        self.queue = JoinableQueue()
        self.processes = [Process(target=self.upload) for i in range(nb_workers)]
        for p in self.processes:
            p.start()

    def render(self, item):
        self.queue.put(item)

    def upload(self):
        while True:
            item = self.queue.get()
            if item is None:
                break

            # process your item here

            self.queue.task_done()

    def terminate(self):
        """ wait until queue is empty and terminate processes """
        self.queue.join()
        for p in self.processes:
            p.terminate()

r = Renderer()
r.render(item1)
r.render(item2)
r.terminate()

Take a look at the new Spatial data-types that were introduced in SQL Server 2008. They are designed for this kind of task and make indexing and querying much easier and more efficient.

More information:

• MS TechNet: SQL Server 2008 Spatial Data Types,

• MSDN: Working with Spatial Data (Database Engine).

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

You could also try the following to add an inline style to the element:

$(this).attr('style', 'text-align: center');

This should make sure that other styling rules aren't overriding what you thought would work. I believe inline styles usually get precedence.

EDIT: Also, another tool that may help you is Jash (http://www.billyreisinger.com/jash/). It gives you a javascript command prompt so you can ensure you easily test javascript statements and make sure you're selecting the right element, etc.

I had the same problem and I think I have the solution.

If your field Application in table Library has a foreign key that references a field in another table (named Application I would bet), then your field Application in table Library has to have a foreign key to table Application too.

After that you can do your composed foreign key.

Excuse my poor english, and sorry if I'm wrong.

mylist[c(5,7,9)] should do it.

You want the sublists returned as sublists of the result list; you don't use [[]] (or rather, the function is [[) for that -- as Dason mentions in comments, [[ grabs the element.

1) "Unnecessarily complicated" is IMHO to create first an unmodifiable List before adding its elements to the ArrayList.

2) The solution matches exact the question: "Is there a way to define an ArrayList with the double type?"

double type:

double[] arr = new double[] {1.38, 2.56, 4.3};

ArrayList:

ArrayList<Double> list = DoubleStream.of( arr ).boxed().collect(
    Collectors.toCollection( new Supplier<ArrayList<Double>>() {
      public ArrayList<Double> get() {
        return( new ArrayList<Double>() );
      }
    } ) );

…and this creates the same compact and fast compilation as its Java 1.8 short-form:

ArrayList<Double> list = DoubleStream.of( arr ).boxed().collect(
    Collectors.toCollection( ArrayList::new ) );

I have no serial device here to test it, but if you have python and dbus you can try it yourself.

import dbus
bus = dbus.SystemBus()
hwmanager = bus.get_object('org.freedesktop.Hal', '/org/freedesktop/Hal/Manager')
hwmanager_i = dbus.Interface(hwmanager, 'org.freedesktop.Hal.Manager')
print hwmanager_i.FindDeviceByCapability("serial")

If it fails you can search inside hwmanager_i.GetAllDevicesWithProperties() to see if the capability name "serial" that I just guessed has a different name.

Numpy solution. We will shuffle the whole dataset first (df.sample(frac=1, random_state=42)) and then split our data set into the following parts:

[int(.6*len(df)), int(.8*len(df))] - is an indices_or_sections array for numpy.split().

Here is a small demo for np.split() usage - let's split 20-elements array into the following parts: 80%, 10%, 10%:

In [45]: a = np.arange(1, 21)

In [46]: a
Out[46]: array([ 1,  2,  3,  4,  5,  6,  7,  8,  9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20])

In [47]: np.split(a, [int(.8 * len(a)), int(.9 * len(a))])
Out[47]:
[array([ 1,  2,  3,  4,  5,  6,  7,  8,  9, 10, 11, 12, 13, 14, 15, 16]),
 array([17, 18]),
 array([19, 20])]

function isValidDate(year, month, day) {
        var d = new Date(year, month - 1, day, 0, 0, 0, 0);
        return (!isNaN(d) && (d.getDate() == day && d.getMonth() + 1 == month && d.getYear() == year));
    }

One very small nit to pick:

The RFC for email addresses allows the first part to include an "@" sign if it is quoted. Example:

"john@work"@myemployer.com

This is quite uncommon, but could happen. Theoretically, you should split on the last "@" symbol, not the first:

SELECT LEN(EmailField) - CHARINDEX('@', REVERSE(EmailField)) + 1

just right click the layout file you want, then select 'Save As', save somewhere, then copy it in 'layout' folder in your android project(eclipse)...

you can see how the layout looks like :)

tl;dr

• "Foo" and "bar" as metasyntactic variables were popularised by MIT and DEC, the first references are in work on LISP and PDP-1 and Project MAC from 1964 onwards.

• Many of these people were in MIT's Tech Model Railroad Club, where we find the first documented use of "foo" in tech circles in 1959 (and a variant in 1958).

• Both "foo" and "bar" (and even "baz") were well known in popular culture, especially from Smokey Stover and Pogo comics, which will have been read by many TMRC members.

• Also, it seems likely the military FUBAR contributed to their popularity.

The use of lone "foo" as a nonsense word is pretty well documented in popular culture in the early 20th century, as is the military FUBAR. (Some background reading: FOLDOC FOLDOC Jargon File Jargon File Wikipedia RFC3092)

OK, so let's find some references.

STOP PRESS! After posting this answer, I discovered this perfect article about "foo" in the Friday 14th January 1938 edition of The Tech ("MIT's oldest and largest newspaper & the first newspaper published on the web"), Volume LVII. No. 57, Price Three Cents:

On Foo-ism

The Lounger thinks that this business of Foo-ism has been carried too far by its misguided proponents, and does hereby and forthwith take his stand against its abuse. It may be that there's no foo like an old foo, and we're it, but anyway, a foo and his money are some party. (Voice from the bleachers- "Don't be foo-lish!")

As an expletive, of course, "foo!" has a definite and probably irreplaceable position in our language, although we fear that the excessive use to which it is currently subjected may well result in its falling into an early (and, alas, a dark) oblivion. We say alas because proper use of the word may result in such happy incidents as the following.

It was an 8.50 Thermodynamics lecture by Professor Slater in Room 6-120. The professor, having covered the front side of the blackboard, set the handle that operates the lift mechanism, turning meanwhile to the class to continue his discussion. The front board slowly, majestically, lifted itself, revealing the board behind it, and on that board, writ large, the symbols that spelled "FOO"!

The Tech newspaper, a year earlier, the Letter to the Editor, September 1937:

By the time the train has reached the station the neophytes are so filled with the stories of the glory of Phi Omicron Omicron, usually referred to as Foo, that they are easy prey.

...

It is not that I mind having lost my first four sons to the Grand and Universal Brotherhood of Phi Omicron Omicron, but I do wish that my fifth son, my baby, should at least be warned in advance.

Hopefully yours,

Indignant Mother of Five.

And The Tech in December 1938:

General trend of thought might be best interpreted from the remarks made at the end of the ballots. One vote said, '"I don't think what I do is any of Pulver's business," while another merely added a curt "Foo."

The first documented "foo" in tech circles is probably 1959's Dictionary of the TMRC Language:

FOO: the sacred syllable (FOO MANI PADME HUM); to be spoken only when under inspiration to commune with the Deity. Our first obligation is to keep the Foo Counters turning.

These are explained at FOLDOC. The dictionary's compiler Pete Samson said in 2005:

Use of this word at TMRC antedates my coming there. A foo counter could simply have randomly flashing lights, or could be a real counter with an obscure input.

And from 1996's Jargon File 4.0.0:

Earlier versions of this lexicon derived 'baz' as a Stanford corruption of bar. However, Pete Samson (compiler of the TMRC lexicon) reports it was already current when he joined TMRC in 1958. He says "It came from "Pogo". Albert the Alligator, when vexed or outraged, would shout 'Bazz Fazz!' or 'Rowrbazzle!' The club layout was said to model the (mythical) New England counties of Rowrfolk and Bassex (Rowrbazzle mingled with (Norfolk/Suffolk/Middlesex/Essex)."

A year before the TMRC dictionary, 1958's MIT Voo Doo Gazette ("Humor suplement of the MIT Deans' office") (PDF) mentions Foocom, in "The Laws of Murphy and Finagle" by John Banzhaf (an electrical engineering student):

Further research under a joint Foocom and Anarcom grant expanded the law to be all embracing and universally applicable: If anything can go wrong, it will!

Also 1964's MIT Voo Doo (PDF) references the TMRC usage:

Yes! I want to be an instant success and snow customers. Send me a degree in: ...

• Foo Counters

• Foo Jung

Let's find "foo", "bar" and "foobar" published in code examples.

So, Jargon File 4.4.7 says of "foobar":

Probably originally propagated through DECsystem manuals by Digital Equipment Corporation (DEC) in 1960s and early 1970s; confirmed sightings there go back to 1972.

The first published reference I can find is from February 1964, but written in June 1963, The Programming Language LISP: its Operation and Applications by Information International, Inc., with many authors, but including Timothy P. Hart and Michael Levin:

Thus, since "FOO" is a name for itself, "COMITRIN" will treat both "FOO" and "(FOO)" in exactly the same way.

Also includes other metasyntactic variables such as: FOO CROCK GLITCH / POOT TOOR / ON YOU / SNAP CRACKLE POP / X Y Z

I expect this is much the same as this next reference of "foo" from MIT's Project MAC in January 1964's AIM-064, or LISP Exercises by Timothy P. Hart and Michael Levin:

car[((FOO . CROCK) . GLITCH)]

It shares many other metasyntactic variables like: CHI / BOSTON NEW YORK / SPINACH BUTTER STEAK / FOO CROCK GLITCH / POOT TOOP / TOOT TOOT / ISTHISATRIVIALEXCERCISE / PLOOP FLOT TOP / SNAP CRACKLE POP / ONE TWO THREE / PLANE SUB THRESHER

For both "foo" and "bar" together, the earliest reference I could find is from MIT's Project MAC in June 1966's AIM-098, or PDP-6 LISP by none other than Peter Samson:

EXPLODE, like PRIN1, inserts slashes, so (EXPLODE (QUOTE FOO/ BAR)) PRIN1's as (F O O // / B A R) or PRINC's as (F O O / B A R).

Some more recallations.

@Walter Mitty recalled on this site in 2008:

I second the jargon file regarding Foo Bar. I can trace it back at least to 1963, and PDP-1 serial number 2, which was on the second floor of Building 26 at MIT. Foo and Foo Bar were used there, and after 1964 at the PDP-6 room at project MAC.

John V. Everett recalls in 1996:

When I joined DEC in 1966, foobar was already being commonly used as a throw-away file name. I believe fubar became foobar because the PDP-6 supported six character names, although I always assumed the term migrated to DEC from MIT. There were many MIT types at DEC in those days, some of whom had worked with the 7090/7094 CTSS. Since the 709x was also a 36 bit machine, foobar may have been used as a common file name there.

Foo and bar were also commonly used as file extensions. Since the text editors of the day operated on an input file and produced an output file, it was common to edit from a .foo file to a .bar file, and back again.

It was also common to use foo to fill a buffer when editing with TECO. The text string to exactly fill one disk block was IFOO$HXA127GA$$. Almost all of the PDP-6/10 programmers I worked with used this same command string.

Daniel P. B. Smith in 1998:

Dick Gruen had a device in his dorm room, the usual assemblage of B-battery, resistors, capacitors, and NE-2 neon tubes, which he called a "foo counter." This would have been circa 1964 or so.

Robert Schuldenfrei in 1996:

The use of FOO and BAR as example variable names goes back at least to 1964 and the IBM 7070. This too may be older, but that is where I first saw it. This was in Assembler. What would be the FORTRAN integer equivalent? IFOO and IBAR?

Paul M. Wexelblat in 1992:

The earliest PDP-1 Assembler used two characters for symbols (18 bit machine) programmers always left a few words as patch space to fix problems. (Jump to patch space, do new code, jump back) That space conventionally was named FU: which stood for Fxxx Up, the place where you fixed Fxxx Ups. When spoken, it was known as FU space. Later Assemblers ( e.g. MIDAS allowed three char tags so FU became FOO, and as ALL PDP-1 programmers will tell you that was FOO space.

Bruce B. Reynolds in 1996:

On the IBM side of FOO(FU)BAR is the use of the BAR side as Base Address Register; in the middle 1970's CICS programmers had to worry out the various xxxBARs...I think one of those was FRACTBAR...

Here's a straight IBM "BAR" from 1955.

Other early references:

• 1967 foo bar MIT AIM-127

I haven't been able to find any references to foo bar as "inverted foo signal" as suggested in RFC3092 and elsewhere.

Here are a some of even earlier F00s but I think they're coincidences/false positives:

• 1959 "FOO 31 IBM-704 Bettis Plant Uses a least squares technique" U.S. Atomic Energy Commission

• 1960 FOO (FO Out, F1, F2, FOO, FOI) "Digital computer and control engineering"

• 1967 FOO?

I think Nosql is "more suitable" in these scenarios at least (more supplementary is welcome)

1. Easy to scale horizontally by just adding more nodes.

2. Query on large data set

   Imagine tons of tweets posted on twitter every day. In RDMS, there could be tables with millions (or billions?) of rows, and you don't want to do query on those tables directly, not even mentioning, most of time, table joins are also needed for complex queries.

3. Disk I/O bottleneck

   If a website needs to send results to different users based on users' real-time info, we are probably talking about tens or hundreds of thousands of SQL read/write requests per second. Then disk i/o will be a serious bottleneck.

SYSDATE and GETDATE perform identically.

SYSDATE is compatible with Oracle syntax, and GETDATE is compatible with Microsoft SQL Server syntax.

Using ES6

We'll use Ramda's equals function, but instead we can use Lodash's or Underscore's isEqual:

const R = require('ramda');

const arraysHaveSameValues = (arr1, arr2) => R.equals( [...arr1].sort(), [...arr2].sort() )

Using the spread opporator, we avoid mutating the original arrays, and we keep our function pure.

I use the object FileReader on the input onchange event for your input file type! This example uses the readAsDataURL function and for that reason you should have an tag. The FileReader object also has readAsBinaryString to get the binary data, which can later be used to create the same file on your server

Example:

var input = document.getElementById("inputFile");
var fReader = new FileReader();
fReader.readAsDataURL(input.files[0]);
fReader.onloadend = function(event){
    var img = document.getElementById("yourImgTag");
    img.src = event.target.result;
}

First you use startActivityForResult() with parameters in first Activity and if you want to send data from second Activity to first Activity then pass value using Intent with setResult() method and get that data inside onActivityResult() method in first Activity.

Simply :

$data = $form->getData();

Use the .Clear method.

Sheets("Test").Range("A1:C3").Clear

@OP,

Is glob pettern not only used for file names?

No, "glob" pattern is not only used for file names. you an use it to compare strings as well. In your examples, you can use case/esac to look for strings patterns.

 gg=svm-grid-ch 
 # looking for the word "grid" in the string $gg
 case "$gg" in
    *grid* ) echo "found";;
 esac

 # [[ $gg =~ ^....grid* ]]
 case "$gg" in ????grid*) echo "found";; esac 

 # [[ $gg =~ s...grid* ]]
 case "$gg" in s???grid*) echo "found";; esac

In bash, when to use glob pattern and when to use regular expression? Thanks!

Regex are more versatile and "convenient" than "glob patterns", however unless you are doing complex tasks that "globbing/extended globbing" cannot provide easily, then there's no need to use regex. Regex are not supported for version of bash <3.2 (as dennis mentioned), but you can still use extended globbing (by setting extglob ). for extended globbing, see here and some simple examples here.

Update for OP: Example to find files that start with 2 characters (the dots "." means 1 char) followed by "g" using regex

eg output

$ shopt -s dotglob
$ ls -1 *
abg
degree
..g

$ for file in *; do [[ $file =~ "..g" ]] && echo $file ; done
abg
degree
..g

In the above, the files are matched because their names contain 2 characters followed by "g". (ie ..g).

The equivalent with globbing will be something like this: (look at reference for meaning of ? and * )

$ for file in ??g*; do echo $file; done
abg
degree
..g

use a simple formula: WHO.WHAT = VALUE

where,

WHO is the element in the storyboard you want to make changes to for eg. label

WHAT is the property of that element you wish to change for eg. text

VALUE is the change that you wish to be displayed

for eg. if I want to change the text from story text to You see a fork in the road in the label as shown in screenshot 1

In this case, our WHO is the label (element in the storyboard), WHAT is the text (property of element) and VALUE will be You see a fork in the road

so our final code will be as follows: Final code

screenshot 1 changes to screenshot 2 once the above code is executed.

I hope this solution helps you solve your issue. Thank you!

Maven can be considered as complete project development tool not just build tool like Ant. You should use Eclipse IDE with maven plugin to fix all your problems.

Here are few advantages of Maven, quoted from the Benefits of using Maven page:

Henning

• quick project setup, no complicated build.xml files, just a POM and go
• all developers in a project use the same jar dependencies due to centralized POM.
• getting a number of reports and metrics for a project "for free"
• reduce the size of source distributions, because jars can be pulled from a central location

Emmanuel Venisse

• a lot of goals are available so it isn't necessary to develop some specific build process part contrary to ANT we can reuse existing ANT tasks in build process with antrun plugin

Jesse Mcconnell

• Promotes modular design of code. by making it simple to manage mulitple projects it allows the design to be laid out into muliple logical parts, weaving these parts together through the use of dependency tracking in pom files.
• Enforces modular design of code. it is easy to pay lipservice to modular code, but when the code is in seperate compiling projects it is impossible to cross pollinate references between modules of code unless you specifically allow for it in your dependency management... there is no 'I'll just do this now and fix it later' implementations.
• Dependency Management is clearly declared. with the dependency management mechanism you have to try to screw up your jar versioning...there is none of the classic problem of 'which version of this vendor jar is this?' And setting it up on an existing project rips the top off of the existing mess if it exists when you are forced to make 'unknown' versions in your repository to get things up and running...that or lie to yourself that you know the actual version of ABC.jar.
• strong typed life cycle there is a strong defined lifecycle that a software system goes thru from the initiation of a build to the end... and the users are allowed to mix and match their system to the lifecycle instead of cobble together their own lifecycle.. this has the additional benefit of allowing people to move from one project to another and speak using the same vocabulary in terms of software building

Vincent Massol

• Greater momentum: Ant is now legacy and not moving fast ahead. Maven is forging ahead fast and there's a potential of having lots of high-value tools around Maven (CI, Dashboard project, IDE integration, etc).

Changing to format: 'dd/mm/yyyy' didn't work for me, and changing that to dateFormat: 'dd/mm/yyyy' added year multiple times, The finest one for me was,

dateFormat: 'dd/mm/yy'

Try this

 echo "hello world" | sed 's/ /./g' 

The complete solution including email addresses in path names for spring 4.2 is

<bean id="contentNegotiationManager"
    class="org.springframework.web.accept.ContentNegotiationManagerFactoryBean">
    <property name="favorPathExtension" value="false" />
    <property name="favorParameter" value="true" />
    <property name="mediaTypes">
        <value>
            json=application/json
            xml=application/xml
        </value>
    </property>
</bean>
<mvc:annotation-driven
    content-negotiation-manager="contentNegotiationManager">
    <mvc:path-matching suffix-pattern="false" registered-suffixes-only="true" />
</mvc:annotation-driven>

Add this to the application-xml

In my case, I needed to use something like this to keep the footer pinned down at the bottom if there is not much content, but not floating on top of everything constantly like data-position="fixed" seems to do...

.ui-content
{
    margin-bottom:75px; /* Set this to whatever your footer size is... */
}

.ui-footer {
    position: absolute !important;
    bottom: 0;
    width: 100%;
}

I believe there is no "out of the box" solution, that's a limitation of the Directory.GetFiles method.

It's fairly easy to write your own method though, here is an example.

The code could be:

/// <summary>
/// Returns file names from given folder that comply to given filters
/// </summary>
/// <param name="SourceFolder">Folder with files to retrieve</param>
/// <param name="Filter">Multiple file filters separated by | character</param>
/// <param name="searchOption">File.IO.SearchOption, 
/// could be AllDirectories or TopDirectoryOnly</param>
/// <returns>Array of FileInfo objects that presents collection of file names that 
/// meet given filter</returns>
public string[] getFiles(string SourceFolder, string Filter, 
 System.IO.SearchOption searchOption)
{
 // ArrayList will hold all file names
ArrayList alFiles = new ArrayList();

 // Create an array of filter string
 string[] MultipleFilters = Filter.Split('|');

 // for each filter find mathing file names
 foreach (string FileFilter in MultipleFilters)
 {
  // add found file names to array list
  alFiles.AddRange(Directory.GetFiles(SourceFolder, FileFilter, searchOption));
 }

 // returns string array of relevant file names
 return (string[])alFiles.ToArray(typeof(string));
}

I think the easiest is to simply open the file in write mode and then close it. For example, if your file myfile.dat contains:

"This is the original content"

Then you can simply write:

f = open('myfile.dat', 'w')
f.close()

This would erase all the content. Then you can write the new content to the file:

f = open('myfile.dat', 'w')
f.write('This is the new content!')
f.close()

application/force-download is not a standard MIME type. It's a hack supported by some browsers, added fairly recently.

Your question doesn't really make any sense. It's like asking why Internet Explorer 4 doesn't support the latest CSS 3 functionality.

If you can have dependency to apache utils you can use org.apache.commons.lang3.SystemUtils.

    System.out.println("Is Java version at least 1.8: " + SystemUtils.isJavaVersionAtLeast(JavaVersion.JAVA_1_8));

With map in instead of each it is possible to avoid the array creation step:

var checkedCheckboxesValues = 
    $('input:checkbox[name="groupName"]:checked')
        .map(function() {
            return $(this).val();
        }).get();

From the map() page of the docs:

Pass each element in the current matched set through a function, producing a new jQuery object containing the return values

get() turns those values into an array.

Path is a new feature of Django 2.0. Explained here : https://docs.djangoproject.com/en/2.0/releases/2.0/#whats-new-2-0

Look like more pythonic way, and enable to not use regular expression in argument you pass to view... you can ue int() function for exemple.

I know this isn't as elegant as the other posts, but it's a more straightforward xaml/codebehind example of how to accomplish the same thing.

Xaml:

<StackPanel Orientation="Horizontal">
   <TextBox Name="TextBox01" VerticalAlignment="Top" HorizontalAlignment="Left" Width="70" />
   <Button Name="Button01" VerticalAlignment="Top" HorizontalAlignment="Left" Margin="10,0,0,0" />
</StackPanel>

CodeBehind:

Private Sub Window1_Loaded(ByVal sender As Object, ByVal e As System.Windows.RoutedEventArgs) Handles Me.Loaded

        Button01.IsEnabled = False
        Button01.Content = "I am Disabled"

End Sub

Private Sub TextBox01_TextChanged(ByVal sender As Object, ByVal e As System.Windows.Controls.TextChangedEventArgs) Handles TextBox01.TextChanged

        If TextBox01.Text.Trim.Length > 0 Then
            Button01.IsEnabled = True
            Button01.Content = "I am Enabled"
        Else
            Button01.IsEnabled = False
            Button01.Content = "I am Disabled"
        End If

End Sub

I don't know if leaving hibernate off the front makes a difference.

The reference suggests it should be hibernate.hbm2ddl.auto

A value of create will create your tables at sessionFactory creation, and leave them intact.

A value of create-drop will create your tables, and then drop them when you close the sessionFactory.

Perhaps you should set the javax.persistence.Table annotation explicitly?

Hope this helps.

A useful function to determine if an arbitrary permission has been blocked from requesting (in Kotlin):

private fun isPermissionBlockedFromAsking(activity: Activity, permission: String): Boolean {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
        return ContextCompat.checkSelfPermission(activity, permission) != PackageManager.PERMISSION_GRANTED
            && !activity.shouldShowRequestPermissionRationale(permission)
            && PreferenceManager.getDefaultSharedPreferences(activity).getBoolean(permission, false)
    }
    return false
}

Use of this requires setting a shared preference boolean with the name of your desired permission (e.g. android.Manifest.permission.READ_PHONE_STATE) to true when you first request a permission.

Explanation:

Build.VERSION.SDK_INT >= Build.VERSION_CODES.M as some of the code may only be run on API level 23+.

ContextCompat.checkSelfPermission(activity, permission) != PackageManager.PERMISSION_GRANTED to check we don't already have the permission.

!activity.shouldShowRequestPermissionRationale(permission) to check whether the user has denied the app asking again. Due to quirks of this function, the following line is also required.

PreferenceManager.getDefaultSharedPreferences(activity).getBoolean(permission, false) this is used (along with setting the value to true on first permission request) to distinguish between the "Never asked" and "Never ask again" states, as the previous line doesn't return this information.

This worked for me using Select2 v4.0.3

//Initialize Select2
 jQuery('.js-select').select2();

// Make Select2 respect tab focus
function select2Focus(){
    jQuery(window).keyup(function (e) {
        var code = (e.keyCode ? e.keyCode : e.which);
        if (code == 9 && jQuery('.select2-search__field:focus').length) {
            jQuery('.js-select').select2('open');
        }
    });
}

select2Focus();

Yes we can check the length of queue object created from collections.

from collections import deque
class Queue():
    def __init__(self,batchSize=32):
        #self.batchSie = batchSize
        self._queue = deque(maxlen=batchSize)

    def enqueue(self, items):
        ''' Appending the items to the queue'''
        self._queue.append(items)

    def dequeue(self):
        '''remoe the items from the top if the queue becomes full '''
        return self._queue.popleft()

Creating an object of class

q = Queue(batchSize=64)
q.enqueue([1,2])
q.enqueue([2,3])
q.enqueue([1,4])
q.enqueue([1,22])

Now retrieving the length of the queue

#check the len of queue
print(len(q._queue)) 
#you can print the content of the queue
print(q._queue)
#Can check the content of the queue
print(q.dequeue())
#Check the length of retrieved item 
print(len(q.dequeue()))

Like Apache, this is a quick edit to the source and recompile. From Calomel.org:

The Server: string is the header which is sent back to the client to tell them what type of http server you are running and possibly what version. This string is used by places like Alexia and Netcraft to collect statistics about how many and of what type of web server are live on the Internet. To support the author and statistics for Nginx we recommend keeping this string as is. But, for security you may not want people to know what you are running and you can change this in the source code. Edit the source file src/http/ngx_http_header_filter_module.c at look at lines 48 and 49. You can change the String to anything you want.

## vi src/http/ngx_http_header_filter_module.c (lines 48 and 49)
static char ngx_http_server_string[] = "Server: MyDomain.com" CRLF;
static char ngx_http_server_full_string[] = "Server: MyDomain.com" CRLF;

March 2011 edit: Props to Flavius below for pointing out a new option, replacing Nginx's standard HttpHeadersModule with the forked HttpHeadersMoreModule. Recompiling the standard module is still the quick fix, and makes sense if you want to use the standard module and won't be changing the server string often. But if you want more than that, the HttpHeadersMoreModule is a strong project and lets you do all sorts of runtime black magic with your HTTP headers.

git mv moves the file, updating the index to record the replaced file path, as well as updating any affected git submodules. Unlike a manual move, it also detects case-only renames that would not otherwise be detected as a change by git.

It is similar (though not identical) in behavior to moving the file externally to git, removing the old path from the index using git rm, and adding the new one to the index using git add.

Answer Motivation

This question has a lot of great partial answers. This answer is an attempt to combine them into a single cohesive answer. Additionally, one thing not called out by any of the other answers is the fact that the man page actually does mostly answer the question, but it's perhaps less obvious than it could be.

Detailed Explanation

Three different effects are called out in the man page:

1. The file, directory, or symlink is moved in the filesystem:

   git-mv - Move or rename a file, a directory, or a symlink

2. The index is updated, adding the new path and removing the previous one:

   The index is updated after successful completion, but the change must still be committed.

3. Moved submodules are updated to work at the new location:

   Moving a submodule using a gitfile (which means they were cloned with a Git version 1.7.8 or newer) will update the gitfile and core.worktree setting to make the submodule work in the new location. It also will attempt to update the submodule.<name>.path setting in the gitmodules(5) file and stage that file (unless -n is used).

As mentioned in this answer, git mv is very similar to moving the file, adding the new path to the index, and removing the previous path from the index:

mv oldname newname
git add newname
git rm oldname

However, as this answer points out, git mv is not strictly identical to this in behavior. Moving the file via git mv adds the new path to the index, but not any modified content in the file. Using the three individual commands, on the other hand, adds the entire file to the index, including any modified content. This could be relevant when using a workflow which patches the index, rather than adding all changes in the file.

Additionally, as mentioned in this answer and this comment, git mv has the added benefit of handling case-only renames on file systems that are case-insensitive but case-preserving, as is often the case in current macOS and Windows file systems. For example, in such systems, git would not detect that the file name has changed after moving a file via mv Mytest.txt MyTest.txt, whereas using git mv Mytest.txt MyTest.txt would successfully update its name.

You could use a javascript snippit

$(function()
{
    // Enable drop menu clicks
    $(".nav li > a").off();
});

That will unbind the click event preventing url changing.

filter: blur(0)
transition: filter .3s ease-out
transition-timing-function: steps(3, end) // add this string with steps equal duration

I was helped by setting the value of transition duration .3s equal transition timing steps .3s

Use "\t". That's the tab space character.

My solution was to change the name of my signing config from the default "config" to "debug". To verify, I changed it to some other random name and got the error again, and then changed it back to "debug" and the error was gone. So while it seems artificial and I tend to not believe this is the whole story, give this solution a try.

exit 1 is all you need. The 1 is a return code, so you can change it if you want, say, 1 to mean a successful run and -1 to mean a failure or something like that.

Don't forget to do this,

Select the Project -- > Build Settings. Search PROVISIONING_PROFILE and delete whatever nonsense is there.

you are turning them into an address but Cells(#,#) uses integer inputs not address inputs so just use lastRow = ActiveSheet.UsedRange.Rows.count and lastColumn = ActiveSheet.UsedRange.Columns.Count

It's your "fault" in that that's how Or is defined, so it's the behaviour you should expect:

In a Boolean comparison, the Or operator always evaluates both expressions, which could include making procedure calls. The OrElse Operator (Visual Basic) performs short-circuiting, which means that if expression1 is True, then expression2 is not evaluated.

But you don't have to endure it. You can use OrElse to get short-circuiting behaviour.

So you probably want:

If (example Is Nothing OrElse Not example.Item = compare.Item) Then
    'Proceed
End If

I can't say it reads terribly nicely, but it should work...

Create a role add this role to users, and then you can grant execute to all the routines in one shot to this role.

CREATE ROLE <abc>
GRANT EXECUTE TO <abc>

This works in SQL Server 2005, I'm not sure about backward compatibility of this feature, I'm sure anything later than 2005 should be fine.
