If you'd like to exclude the false or empty rows (such as 0 => ''), where using empty() will fail, you can try:

if (array_filter($playerlist) == []) {
  // Array is empty!
}

array_filter(): If no callback is supplied, all entries of array equal to FALSE (see converting to boolean) will be removed.

If you'd like to remove all NULL, FALSE and empty strings (''), but leave zero values (0), you can use strlen as a callback, e.g.:

$is_empty = array_filter($playerlist, 'strlen') == [];

Note, while the above answers are correct, if you want, you can do something like:

alert("The variable named x1 has value:  " + x1);

Try disabling Project->Build Automatically.

As Scorpio suggested, there's a process running that's got a lock on a file somewhere.

I have a large multi-module maven project that regularly fails on clean and this resolves it for me. I re-enable Build Automatically when I'm done.

As already stated, you cannot decrypt MD5 without attempting something like brute force hacking which is extremely resource intensive, not practical, and unethical.

However you could use something like this to encrypt / decrypt passwords/etc safely:

$input = "SmackFactory";

$encrypted = encryptIt( $input );
$decrypted = decryptIt( $encrypted );

echo $encrypted . '<br />' . $decrypted;

function encryptIt( $q ) {
    $cryptKey  = 'qJB0rGtIn5UB1xG03efyCp';
    $qEncoded      = base64_encode( mcrypt_encrypt( MCRYPT_RIJNDAEL_256, md5( $cryptKey ), $q, MCRYPT_MODE_CBC, md5( md5( $cryptKey ) ) ) );
    return( $qEncoded );
}

function decryptIt( $q ) {
    $cryptKey  = 'qJB0rGtIn5UB1xG03efyCp';
    $qDecoded      = rtrim( mcrypt_decrypt( MCRYPT_RIJNDAEL_256, md5( $cryptKey ), base64_decode( $q ), MCRYPT_MODE_CBC, md5( md5( $cryptKey ) ) ), "\0");
    return( $qDecoded );
}

Using a encypted method with a salt would be even safer, but this would be a good next step past just using a MD5 hash.

In git bash, stashing of untracked files is achieved by using the command

git stash --include-untracked
# or
git stash -u

http://git-scm.com/docs/git-stash

git stash removes any untracked or uncommited files from your workspace. And you can revert git stash by using following commands

git stash pop

This will place the file back in your local workspace.

My experience

I had to perform a modification to my gitIgnore file to avoid movement of .classpath and .project files into remote repo. I am not allowed to move this modified .gitIgnore in remote repo as of now.

.classpath and .project files are important for eclipse - which is my java editor.

I first of all selectively added my rest of the files and committed for staging. However, final push cannot be performed unless the modified .gitIgnore fiels and the untracked files viz. .project and .classpath are not stashed.

I used

git stash

for stashing the modified .gitIgnore file.

For stashing .classpath and .project file, I used

git stash --include-untracked

and it removed the files from my workspace. Absence of these files takes away my capability of working on my work location in eclipse. I proceeded on with completing the procedure for pushing the committed files to remote. Once this was done successfully, I used

git stash pop

This pasted the same files back in my workspace. This gave back to me my ability to work on the same project in eclipse. Hope this brushes aside misconceptions.

Casting int to char is done simply by assigning with the type in parenthesis:

int i = 65535;
char c = (char)i;

Note: I thought that you might be losing data (as in the example), because the type sizes are different.

Appending characters to characters cannot be done (unless you mean arithmetics, then it's simple operators). You need to use strings, AKA arrays of characters, and <string.h> functions like strcat or sprintf.

Use sprintf.

int sprintf ( char * str, const char * format, ... );

Write formatted data to string Composes a string with the same text that would be printed if format was used on printf, but instead of being printed, the content is stored as a C string in the buffer pointed by str.

The size of the buffer should be large enough to contain the entire resulting string (see snprintf for a safer version).

A terminating null character is automatically appended after the content.

After the format parameter, the function expects at least as many additional arguments as needed for format.

Parameters:

str

Pointer to a buffer where the resulting C-string is stored. The buffer should be large enough to contain the resulting string.

format

C string that contains a format string that follows the same specifications as format in printf (see printf for details).

... (additional arguments)

Depending on the format string, the function may expect a sequence of additional arguments, each containing a value to be used to replace a format specifier in the format string (or a pointer to a storage location, for n). There should be at least as many of these arguments as the number of values specified in the format specifiers. Additional arguments are ignored by the function.

Example:

// Allocates storage
char *hello_world = (char*)malloc(13 * sizeof(char));
// Prints "Hello world!" on hello_world
sprintf(hello_world, "%s %s!", "Hello", "world");

Ok, maybe I'm missing something here, but this is the way I do it:

public static Byte[] ToByteArray(this Stream stream) {
    Int32 length = stream.Length > Int32.MaxValue ? Int32.MaxValue : Convert.ToInt32(stream.Length);
    Byte[] buffer = new Byte[length];
    stream.Read(buffer, 0, length);
    return buffer;
}

Most of you already know this by now, but I am posting this, just incase, some of you are still struggling with JSON in iOS6+.

In iOS6 and later, we have the NSJSONSerialization Class that is fast and has no dependency on including "outside" libraries.

NSDictionary *result = [NSJSONSerialization JSONObjectWithData:[resultStr dataUsingEncoding:NSUTF8StringEncoding] options:0 error:nil]; 

This is the way iOS6 and later can now parse JSON efficiently.The use of SBJson is also pre-ARC implementation and brings with it those issues too if you are working in an ARC environment.

I hope this helps!

Well, you just fire the desired click event:

$(".first").click(function(){
    $(".second").click(); 
    return false;
});

Another solution could be using jquery button selector inside the if else statement $("#buttonId").text("your text");

function showFilterItem() {
if (filterstatus == 0) {
    filterstatus = 1;
    $find('<%=FileAdminRadGrid.ClientID %>').get_masterTableView().showFilterItem();
    $("#ShowButton").text("Hide Filter");
}
else {
    filterstatus = 0;
    $find('<%=FileAdminRadGrid.ClientID %>').get_masterTableView().hideFilterItem();
     $("#ShowButton").text("Show Filter");
}}

• I have implemented this code with my app got such result. You can add number of button in swipe cell.

  Here is implemented screen shots

  After swipe the cell 3 buttons appears "More","Share","Delete".

Forge's SHA-256 implementation is fast and reliable.

To run tests on several SHA-256 JavaScript implementations, go to http://brillout.github.io/test-javascript-hash-implementations/.

The results on my machine suggests forge to be the fastest implementation and also considerably faster than the Stanford Javascript Crypto Library (sjcl) mentioned in the accepted answer.

Forge is 256 KB big, but extracting the SHA-256 related code reduces the size to 4.5 KB, see https://github.com/brillout/forge-sha256

Here is how I got it to work in IE8:

1. Go to the website in question, https://xxx.yyy.com, for instance,
2. Click through until you get to the Certificate error in the browser status line.
3. View the cert, then from the Details tab, select Copy to File.
4. Save to the desktop as xxx.cer, for example,
5. Start, Run, MMC.
6. File, Add/Remove Snap-In,
7. Select Certificates, Click Add, My User Account, then Finish, then OK,
8. Dig down to Trust Root Certification Authorities, Certificates,
9. Right-Click Certificate, Select All Tasks, Import,
10. Select the Save Cert from the Desktop
11. Select Place all Certificates in the following Store, Click Browse,
12. Check the Box that says Show Physical Stores, Expand out Trusted Root Certification Authorities, and select Local Computer there, click OK, Complete the Import,
13. Check the list to make sure it shows up. You will probably need to Refresh before you see it. Exit MMC,
14. Open Browser, select Tools, Delete Browsing History
15. Select all but Inprivate Filtering Data, complete,
16. Go to Internet Options, Content Tab, Clear SSL State,
17. Close browser and reopen and test.

A combination of @grahamparks and @snowindy answers with a couple of modifications is what worked for my Groovy scripts running on Tomcat:

Utils.groovy

class Utils {
    def doSth() {...}
}

MyScript.groovy:

/* import Utils --> This import does not work. The class is not even defined at this time */
Class groovyClass = new GroovyClassLoader(getClass().getClassLoader()).parseClass(new File("full_path_to/Utils.groovy")); // Otherwise it assumes current dir is $CATALINA_HOME
def foo = groovyClass.newInstance(); // 'def' solves compile time errors!!
foo.doSth(); // Actually works!

With a Maven build, you can add the @XmlRootElement annotation

with the "jaxb2-basics-annotate" plug-in.

This answer uses promises, a JavaScript feature of the ECMAScript 6 standard. If your target platform does not support promises, polyfill it with PromiseJs.

Promises are a new (and a lot better) way to handle asynchronous operations in JavaScript:

$('a.button').click(function(){
    if (condition == 'true'){
        function1(someVariable).then(function() {
            //this function is executed after function1
            function2(someOtherVariable);
        });
    }
    else {
        doThis(someVariable);
    }
});


function function1(param, callback) {
    return new Promise(function (fulfill, reject){
        //do stuff
        fulfill(result); //if the action succeeded
        reject(error); //if the action did not succeed
    });
} 

This may seem like a significant overhead for this simple example, but for more complex code it is far better than using callbacks. You can easily chain multiple asynchronous calls using multiple then statements:

function1(someVariable).then(function() {
    function2(someOtherVariable);
}).then(function() {
    function3();
});

You can also wrap jQuery deferrds easily (which are returned from $.ajax calls):

Promise.resolve($.ajax(...params...)).then(function(result) {
    //whatever you want to do after the request
});

As @charlietfl noted, the jqXHR object returned by $.ajax() implements the Promise interface. So it is not actually necessary to wrap it in a Promise, it can be used directly:

$.ajax(...params...).then(function(result) {
    //whatever you want to do after the request
});

Switch statements can often be replaced by a good OO design.

For example, you have an Account class, and are using a switch statement to perform a different calculation based on the type of account.

I would suggest that this should be replaced by a number of account classes, representing the different types of account, and all implementing an Account interface.

The switch then becomes unnecessary, as you can treat all types of accounts the same and thanks to polymorphism, the appropriate calculation will be run for the account type.

add CSS or class to the input element which works in select and text tags like

style="pointer-events: none;background-color:#E9ECEF"

You can also do it using phpmyadmin. Just select the table than go to actions. And change the Auto increment below table options. Don't forget to click on start

Judging by your other post: How to Get the inner text of a span in PHP. You're quite new to web programming, and need to learn about the differences between code on the client (JavaScript) and code on the server (PHP).

As for the correct approach to grabbing the span text from the client I recommend Johns answer.

These are a good place to get started.

JavaScript: https://stackoverflow.com/questions/11246/best-resources-to-learn-javascript

PHP: https://stackoverflow.com/questions/772349/what-is-a-good-online-tutorial-for-php

Also I recommend using jQuery (Once you've got some JavaScript practice) it will eliminate most of the cross-browser compatability issues that you're going to have. But don't use it as a crutch to learn on, it's good to understand JavaScript too. http://jquery.com/

Use Enumerable.Select<TSource, TResult> Method (IEnumerable<TSource>, Func<TSource, Int32, TResult>)

list = list.Cast<object>().Select( (v, i) => new {Value= v, Index = i});

foreach(var row in list)
{
    bool IsChecked = (bool)((CheckBox)DataGridDetail.Columns[0].GetCellContent(row.Value)).IsChecked;
    row.Index ...
}

Assuming this is a windows system and we are using gradle-2.1-all [Applicable to any gradle version, just change the version as we need]

All the gradles can be found in http://services.gradle.org/distributions/

Check the <Your Project>\gradle\wrapper\gradle-wrapper.properties Make sure the distributionUrl is

distributionUrl=http\://services.gradle.org/distributions/gradle-2.1-all.zip

This is enough as it will automatically download the gradle.

After doing the above stuff, if you have downloaded the zip, paste the gradle-2.1-all.zip in

C:\Users\<username>\.gradle\wrapper\dists\gradle-2.1-all\<some_hash_key>\

It will save the extra downloading time.

if you don't know the value of XML Element, you can use

$value = (string) $xml->code[0]->lat;

if (ctype_digit($value)) {
    // the value is probably an integer because consists only of digits
}

It works when you need to determine if value is a number, because (string) will always return string and is_int($value) returns false

Try this formula

=SMALL((A1,C1,E1),INDEX(FREQUENCY((A1,C1,E1),0),1)+1)

Both SMALL and FREQUENCY functions accept "unions" as arguments, i.e. single cell references separated by commas and enclosed in brackets like (A1,C1,E1).

So the formula uses FREQUENCY and INDEX to find the number of zeroes in a range and if you add 1 to that you get the k value such that the kth smallest is always the minimum value excluding zero.

I'm assuming you don't have negative numbers.....

What do you get from running which port as your regular user account? Try it from a freshly opened terminal. Try again after renaming .bash_profile to .profile. Can you run port as a regular user, even with no arguments?

The answer was already given, but I just want to give my piece of cake. What you want to achieve is called method borrowing in the context of JS, that when we take a method from an object and call it in the context of another object. It is quite common to take array methods and apply them to arguments. Let me give you an example.

So we have "super" hashing function which takes two numbers as an argument and returns "super safe" hashed string:

function hash() {
  return arguments[0]+','+arguments[1];
}

hash(1,2); // "1,2" whoaa

So far so good, but we have little problem with the above approach, it is constrained, only works with two numbers, that is not dynamic, let's make it work with any number and plus you do not have to pass an array (you can if you still insist). Ok, Enough talk, Let's fight!

The natural solution would be to use arr.join method:

function hash() {
  return arguments.join();
}

hash(1,2,4,..); //  Error: arguments.join is not a function

Oh, man. Unfortunately, that won’t work. Because we are calling hash(arguments) and arguments object is both iterable and array-like, but not a real array. How about the below approach?

function hash() {
  return [].join.call(arguments);
}

hash(1,2,3,4); // "1,2,3,4" whoaa

The trick is called method borrowing.

We borrow a join method from a regular array [].join. And use [].join.call to run it in the context of arguments.

Why does it work?

That’s because the internal algorithm of the native method arr.join(glue) is very simple.

Taken from the specification almost “as-is”:

Let glue be the first argument or, if no arguments, then a comma ",".
Let result be an empty string.
Append this[0] to result.
Append glue and this[1].
Append glue and this[2].
…Do so until this.length items are glued.
Return result.

So, technically it takes this and joins this[0], this[1] …etc together. It’s intentionally written in a way that allows any array-like this (not a coincidence, many methods follow this practice). That’s why it also works with this=arguments.

Logic index:

d<-d[!(d$A=="B" & d$E==0),]

I lean towards method #1 (a unified Section table), for the sake of efficiently retrieving entire policies with all their sections (which I assume your system will be doing a lot).

Further, I don't know what version of SQL Server you're using, but in 2008+ Sparse Columns help optimize performance in situations where many of the values in a column will be NULL.

Ultimately, you'll have to decide just how "similar" the policy sections are. Unless they differ substantially, I think a more-normalized solution might be more trouble than it's worth... but only you can make that call. :)

I'm not sure how you might do this with Node, but the general idea would be to send an HTTP HEAD request to the URL you're interested in.

HEAD

Asks for the response identical to the one that would correspond to a GET request, but without the response body. This is useful for retrieving meta-information written in response headers, without having to transport the entire content.

Something like this, based it on this question:

var cli = require('cli');
var http = require('http');
var url = require('url');

cli.parse();

cli.main(function(args, opts) {
        this.debug(args[0]);

        var siteUrl = url.parse(args[0]);
        var site = http.createClient(80, siteUrl.host);
        console.log(siteUrl);

        var request = site.request('HEAD', siteUrl.pathname, {'host' : siteUrl.host})
        request.end();

        request.on('response', function(response) {
                response.setEncoding('utf8');
                console.log('STATUS: ' + response.statusCode);
                response.on('data', function(chunk) {
                        console.log("DATA: " + chunk);
                });
        });
});

The most obvious solutions are already listed. Depending on where the query is sat (i.e. in application code) you can't always use IF statements and the inline CASE statements can get painful where lots of columns become conditional. Assuming Col1 + Col3 + Col7 are the same type, and likewise Col2, Col4 + Col8 you can do this:

SELECT Col1, Col2 FROM tbl WHERE @Var LIKE 'xyz'
UNION ALL
SELECT Col3, Col4 FROM tbl WHERE @Var LIKE 'zyx'
UNION ALL
SELECT Col7, Col8 FROM tbl WHERE @Var NOT LIKE 'xyz' AND @Var NOT LIKE 'zyx'

As this is a single command there are several performance benefits with regard to plan caching. Also the Query Optimiser will quickly eliminate those statements where @Var doesn't match the appropriate value without touching the storage engine.

Use summarise in the dplyr package:

library(dplyr)
summarise(df, Average = mean(col_name, na.rm = T))

note: dplyr supports both summarise and summarize.

Try (in your <head> section, or existing css definitions)...

<style>
  body {
   margin:0;
   padding:0;
  }
</style>

Like many stated already, A pretty simple way to do this using JSON.simple as below

import org.json.JSONObject;

String someJsonString = "{name:"MyNode", width:200, height:100}";
JSONObject jsonObj = new JSONObject(someJsonString);

And then use jsonObj to deal with JSON Object. e.g jsonObj.get("name");

As per the below link, JSON.simple is showing constant efficiency for both small and large JSON files

http://blog.takipi.com/the-ultimate-json-library-json-simple-vs-gson-vs-jackson-vs-json/

The best way in my eyes is to use the concat() method provided by the String class itself.

The useage would, in your case, look like this:

String myConcatedString = cursor.getString(numcol).concat('-').
       concat(cursor.getString(cursor.getColumnIndexOrThrow(db.KEY_DESTINATIE)));

If you need to connect to LocalDB during development, you can use:

sqlcmd -S "(localdb)\MSSQLLocalDB" -d dbname -i file.sql

Even I had same problem, The reason was mysql service was not getting configured properly, when I installed it through 'MySQL installer'. Also it was not starting, when I tried to start the service manually.

So in my case it seemed be a Bug with the 'MySQL Installer', as editing the install path to a different one when the 'Developer default' was selected, the problem occurs.

Solution (Not exactly a solution):

• Uninstalled the MySQL all products (completely)
• Reinstalled, this time also I have selected 'Developer default', but didn't make any changes to the path or any thing. So the path was just 'C:\Program Files\MySQL' (the default one)
• And just clicked Next Next...
• Done, this time MySql was running fine.

On the same note, if your server supports both http and https you can connect using:

var socket = io.connect('//localhost');

to auto detect the browser scheme and connect using http/https accordingly. when in https, the transport will be secured by default, as connecting using

var socket = io.connect('https://localhost');

will use secure web sockets - wss:// (the {secure: true} is redundant).

for more information on how to serve both http and https easily using the same node server check out this answer.

This lets you visualize that a command is still executing:

while :;do echo -n .;sleep 1;done &
trap "kill $!" EXIT  #Die with parent if we die prematurely
tar zxf packages.tar.gz; # or any other command here
kill $! && trap " " EXIT #Kill the loop and unset the trap or else the pid might get reassigned and we might end up killing a completely different process

This will create an infinite while loop that executes in the background and echoes a "." every second. This will display . in the shell. Run the tar command or any a command you want. When that command finishes executing then kill the last job running in the background - which is the infinite while loop.

The method find will return the character position in a string. Then, if you want remove every thing from the character, do this:

mystring = "123?567"
mystring[ 0 : mystring.index("?")]

>> '123'

If you want to keep the character, add 1 to the character position.

I don't think there's a jQuery-way to directly access the pseudoclass' rules, but you could always append a new style element to the document's head like:

$('head').append('<style>.column:before{width:800px !important;}</style>');

See a live demo here

I also remember having seen a plugin that tackles this issue once but I couldn't find it on first googling unfortunately.

You can also try mapping framework based on Dozer, but with Excel mapping declaration. They've got some tools and additional cool features. Check at http://openl-tablets.sf.net/mapper

Use following code:

[self.navigationItem setRightBarButtonItem:customBtn];

The difference lies in the fact that ./gradlew indicates you are using a gradle wrapper. The wrapper is generally part of a project and it facilitates installation of gradle. If you were using gradle without the wrapper you would have to manually install it - for example, on a mac brew install gradle and then invoke gradle using the gradle command. In both cases you are using gradle, but the former is more convenient and ensures version consistency across different machines.

Each Wrapper is tied to a specific version of Gradle, so when you first run one of the commands above for a given Gradle version, it will download the corresponding Gradle distribution and use it to execute the build.

Not only does this mean that you don’t have to manually install Gradle yourself, but you are also sure to use the version of Gradle that the build is designed for. This makes your historical builds more reliable

Read more here - https://docs.gradle.org/current/userguide/gradle_wrapper.html

Also, Udacity has a neat, high level video explaining the concept of the gradle wrapper - https://www.youtube.com/watch?v=1aA949H-shk

"abcdefgh..".IndexOf("d")

returns 3

In general returns first occurrence index, if not present returns -1

I assume you are on Windows. Instead of trying to run your program by double clicking on it's icon or clicking a button in your IDE, open up a command prompt, cd to the directory your program is in, and run it by typing its name on the command line.

The javascript built-in reduce for Arrays is not a standard, but you can use underscore.js:

var data = _.range(10);
var sum = _(data).reduce(function(memo, i) {return memo + i});

which becomes

var sumMyData = _(myData).reduce(function(memo, i) {return memo + i[1]}, 0);

for your case. Have a look at this fiddle also.

You have two options to drop and recreate the procedure in SQL Server 2016.

Starting from SQL Server 2016 - use IF EXISTS

DROP FUNCTION [ IF EXISTS ] { [ schema_name. ] function_name } [ ,...n ]   [;]

Starting from SQL Server 2016 SP1 - use OR ALTER

CREATE [ OR ALTER ] FUNCTION [ schema_name. ] function_name   

The reason may be that watcher is declared as local variable to a method and it is garbage collected when the method finishes. You should declare it as a class member. Try the following:

FileSystemWatcher watcher;

private void watch()
{
  watcher = new FileSystemWatcher();
  watcher.Path = path;
  watcher.NotifyFilter = NotifyFilters.LastAccess | NotifyFilters.LastWrite
                         | NotifyFilters.FileName | NotifyFilters.DirectoryName;
  watcher.Filter = "*.*";
  watcher.Changed += new FileSystemEventHandler(OnChanged);

When I were trying install librosa package with pip (pip install librosa), this error were appeared:

ERROR: Cannot uninstall 'llvmlite'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.

I tried to remove llvmlite, but pip uninstall could not remove it. So, I used capability of ignore of pip by this code:

pip install librosa --ignore-installed llvmlite

Indeed, you can use this rule for ignoring a package you don't want to consider:

pip install {package you want to install} --ignore-installed {installed package you don't want to consider}

Have the element display as a block:

display: block;

gt = next Tap gT = previous Tab

There is a misunderstanding here with respect to what a "fork" is. A fork is in fact nothing more than a set of per-user branches. When you push to a fork you actually do push to the original repository, because that is the ONLY repository.

You can try this out by pushing to a fork, noting the commit and then going to the original repository and using the commit ID, you'll see that the commit is "in" the original repository.

This makes a lot of sense, but it is far from obvious (I only discovered this accidentally recently).

When John forks repository SuperProject what seems to actually happen is that all branches in the source repository are replicated with a name like "John.master", "John.new_gui_project", etc.

GitHub "hides" the "John." from us and gives us the illusion we have our own "copy" of the repository on GitHub, but we don't and nor is one even needed.

So my fork's branch "master" is actually named "Korporal.master", but the GitHub UI never reveals this, showing me only "master".

This is pretty much what I think goes on under the hood anyway based on stuff I've been doing recently and when you ponder it, is very good design.

For this reason I think it would be very easy for Microsoft to implement Git forks in their Visual Studio Team Services offering.

You need %in% instead of ==:

library(dplyr)
target <- c("Tom", "Lynn")
filter(dat, name %in% target)  # equivalently, dat %>% filter(name %in% target)

Produces

  days name
1   88 Lynn
2   11  Tom
3    1  Tom
4  222 Lynn
5    2 Lynn

To understand why, consider what happens here:

dat$name == target
# [1] FALSE FALSE FALSE FALSE FALSE FALSE FALSE  TRUE

Basically, we're recycling the two length target vector four times to match the length of dat$name. In other words, we are doing:

 Lynn == Tom
  Tom == Lynn
Chris == Tom
 Lisa == Lynn
 ... continue repeating Tom and Lynn until end of data frame

In this case we don't get an error because I suspect your data frame actually has a different number of rows that don't allow recycling, but the sample you provide does (8 rows). If the sample had had an odd number of rows I would have gotten the same error as you. But even when recycling works, this is clearly not what you want. Basically, the statement dat$name == target is equivalent to saying:

return TRUE for every odd value that is equal to "Tom" or every even value that is equal to "Lynn".

It so happens that the last value in your sample data frame is even and equal to "Lynn", hence the one TRUE above.

To contrast, dat$name %in% target says:

for each value in dat$name, check that it exists in target.

Very different. Here is the result:

[1]  TRUE  TRUE FALSE FALSE FALSE  TRUE  TRUE  TRUE

Note your problem has nothing to do with dplyr, just the mis-use of ==.

You can use this:

ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)" 

to install homebrew.

The best method would be using some JSON library, e.g. Jackson ( http://jackson.codehaus.org ).

But if this is not an option simply escape msget before adding it to your string:

The wrong way to do this is

String msgetEscaped = msget.replaceAll("\"", "\\\"");

Either use (as recommended in the comments)

String msgetEscaped = msget.replace("\"", "\\\"");

or

String msgetEscaped = msget.replaceAll("\"", "\\\\\"");

A sample with all three variants can be found here: http://ideone.com/Nt1XzO

All necessary git bash commands to push and pull into Github:

git status 
git pull
git add filefullpath

git commit -m "comments for checkin file" 
git push origin branch/master
git remote -v 
git log -2 

If you want to edit a file then:

edit filename.* 

To see all branches and their commits:

git show-branch

I received the same error with RENAME USER and GRANTS aren't covered by the currently accepted solution:

The most reliable way seems to be to run SHOW GRANTS for the old user, find/replace what you want to change regarding the user's name and/or host and run them and then finally DROP USER the old user. Not forgetting to run FLUSH PRIVILEGES (best to run this after adding the new users' grants, test the new user, then drop the old user and flush again for good measure).

    > SHOW GRANTS FOR 'olduser'@'oldhost';

You need to tell manage.py the local ip address and the port to bind to. Something like python manage.py runserver 192.168.23.12:8000. Then use that same ip and port from the other machine. You can read more about it here in the documentation.

From a practical standpoint, every table--even a denormalized table like a warehouse table--should have a primary key. Or, failing that, it should at least have a unique, non-nullable index.

Without some kind of unique key, duplicate records can (and will) appear in the table, which is very problematic both for ORM layers and also for basic comprehension of the data. A table that has duplicate records is probably a symptom of bad design.

At the very least, the table should at least have an identity column. Adding an auto-generating ID column takes about 2 minutes in SQL Server and 5 minutes in Oracle. For that extra bit of effort, many, many problems will be avoided.

It could be dependent upon what is supported by the module you are trying to compile. If your makefile is generated by using autotools, use:

--prefix=<myinstalldir>

when running the ./configure

some packages allow you to also override when running:

make prefix=<myinstalldir>

however, if your not using ./configure, only way to know for sure is to open up the makefile and check. It should be one of the first few variables at the top.

Following worked for me;

 $(window).unload(function(event) {
    if(event.clientY < 0) {
        //do whatever you want when closing the window..
    }
 });

Using just awk you could do (I also shortened some of your piping):

strings -a libAddressDoctor5.so | awk '/EngineVersion/ { if(NR==2) { gsub("\"",""); print $2 } }'

I can't verify it for you because I don't know your exact input, but the following works:

echo "Blah EngineVersion=\"123\"" | awk '/EngineVersion/ { gsub("\"",""); print $2 }'

See also this question on removing single quotes.

Add -lm to your link options, since pow() and floor() are part of the math library:

gcc fib.c -o fibo -lm

Evaluating "1,2,3" results in (1, 2, 3), a tuple. As you've discovered, tuples are immutable. Convert to a list before processing.

My Workaround (after much trial and error):

• In order to get around this issue, I had to get the full name of the 'upstream' Docker container, found by running docker network inspect my-special-docker-network and getting the full name property of the upstream container as such:

  "Containers": {
       "39ad8199184f34585b556d7480dd47de965bc7b38ac03fc0746992f39afac338": {
            "Name": "my_upstream_container_name_1_2478f2b3aca0",
  

• Then used this in the NGINX my-network.local.conf file in the location block of the proxy_pass property: (Note the addition of the GUID to the container name):

  location / {
      proxy_pass http://my_upsteam_container_name_1_2478f2b3aca0:3000;
  

As opposed to the previously working, but now broken:

    location / {
        proxy_pass http://my_upstream_container_name_1:3000

Most likely cause is a recent change to Docker Compose, in their default naming scheme for containers, as listed here.

This seems to be happening for me and my team at work, with latest versions of the Docker nginx image:

• I've opened issues with them on the docker/compose GitHub here

For SQL Server 2008, the command is:

ALTER DATABASE ExampleDB SET RECOVERY SIMPLE
DBCC SHRINKFILE('ExampleDB_log', 0, TRUNCATEONLY)
ALTER DATABASE ExampleDB SET RECOVERY FULL

This reduced my 14GB log file down to 1MB.

Is this what you are looking for ?

Sub getRowCol()

    Range("A1").Select ' example

    Dim col, row
    col = Split(Selection.Address, "$")(1)
    row = Split(Selection.Address, "$")(2)

    MsgBox "Column is : " & col
    MsgBox "Row is : " & row

End Sub

jQuery version would be something like below:

function load(recieving_id){
    $('#roommate_but').prop('disabled', true);
    $.get('include.inc.php?i=' + recieving_id, function(data) {
        $("#roommate_but").html(data);
    });
}

If you are trying to do an in-place update of text within a file, this is much easier to reason about in my mind.

grep -Rl text_to_find directory_to_search 2>/dev/null | while read line; do  sed -i 's/text_to_find/replacement_text/g' $line; done

Use a list instead and replace your foreach loop with a for loop:

@model IList<BlockedIPViewModel>

@using (Html.BeginForm()) 
{ 
    @Html.AntiForgeryToken()

    @for (var i = 0; i < Model.Count; i++) 
    {
        <tr>
            <td>
                @Html.HiddenFor(x => x[i].IP)           
                @Html.CheckBoxFor(x => x[i].Checked)
            </td>
            <td>
                @Html.DisplayFor(x => x[i].IP)
            </td>
        </tr>
    }
    <div>
        <input type="submit" value="Unblock IPs" />
    </div>
}

Alternatively you could use an editor template:

@model IEnumerable<BlockedIPViewModel>

@using (Html.BeginForm()) 
{ 
    @Html.AntiForgeryToken()
    @Html.EditorForModel()   
    <div>
        <input type="submit" value="Unblock IPs" />
    </div>
}

and then define the template ~/Views/Shared/EditorTemplates/BlockedIPViewModel.cshtml which will automatically be rendered for each element of the collection:

@model BlockedIPViewModel
<tr>
    <td>
        @Html.HiddenFor(x => x.IP)
        @Html.CheckBoxFor(x => x.Checked)
    </td>
    <td>
        @Html.DisplayFor(x => x.IP)
    </td>
</tr>

The reason you were getting null in your controller is because you didn't respect the naming convention for your input fields that the default model binder expects to successfully bind to a list. I invite you to read the following article.

Once you have read it, look at the generated HTML (and more specifically the names of the input fields) with my example and yours. Then compare and you will understand why yours doesn't work.

The docs indicate that numpy.correlate is not what you are looking for:

numpy.correlate(a, v, mode='valid', old_behavior=False)[source]
  Cross-correlation of two 1-dimensional sequences.
  This function computes the correlation as generally defined in signal processing texts:
     z[k] = sum_n a[n] * conj(v[n+k])
  with a and v sequences being zero-padded where necessary and conj being the conjugate.

Instead, as the other comments suggested, you are looking for a Pearson correlation coefficient. To do this with scipy try:

from scipy.stats.stats import pearsonr   
a = [1,4,6]
b = [1,2,3]   
print pearsonr(a,b)

This gives

(0.99339926779878274, 0.073186395040328034)

You can also use numpy.corrcoef:

import numpy
print numpy.corrcoef(a,b)

This gives:

[[ 1.          0.99339927]
 [ 0.99339927  1.        ]]

Just check our own JSTL wiki page for the proper download links and crystal clear installation instructions.

Put your mouse above the [jstl] tag which you put on the question yourself until a black box shows up and click therein the info link.

Then scroll a bit down to JSTL versions information until you find download link to JSTL 1.2 (or 1.2.1).

Finally just drop exactly that file in webapp's /WEB-INF/lib.

This way the taglib declaration must not give any errors anymore and the JSTL tags and functions should just work.

Short answer: it's closely related to the Content-Security-Policy: upgrade-insecure-requests response header, indicating that the browser supports it (and in fact prefers it).

It took me 30mins of Googling, but I finally found it buried in the W3 spec.

The confusion comes because the header in the spec was HTTPS: 1, and this is how Chromium implemented it, but after this broke lots of websites that were poorly coded (particularly WordPress and WooCommerce) the Chromium team apologized:

"I apologize for the breakage; I apparently underestimated the impact based on the feedback during dev and beta."
— Mike West, in Chrome Issue 501842

Their fix was to rename it to Upgrade-Insecure-Requests: 1, and the spec has since been updated to match.

Anyway, here is the explanation from the W3 spec (as it appeared at the time)...

The HTTPS HTTP request header field sends a signal to the server expressing the client’s preference for an encrypted and authenticated response, and that it can successfully handle the upgrade-insecure-requests directive in order to make that preference as seamless as possible to provide.

...

When a server encounters this preference in an HTTP request’s headers, it SHOULD redirect the user to a potentially secure representation of the resource being requested.

When a server encounters this preference in an HTTPS request’s headers, it SHOULD include a Strict-Transport-Security header in the response if the request’s host is HSTS-safe or conditionally HSTS-safe [RFC6797].

By default, IE displays webpages in the Intranet zone in compatibility view. To change this:

• Press Alt to display the IE menu.
• Choose Tools | Compatibility View settings
• Remove the checkmark next to Display intranet sites in Compatibility View.
• Choose Close.

At this point, IE should rely on the webpage itself (or any relevant group policies) to determine the compatibility settings for your Intranet webpages.

Note that certain sites may no longer function correctly after making this change. You can use the same dialog box to add specific sites to enable compatibility view when needed.

I have stumbled across this question and I will submit my answer that I used and worked pretty well. I had a search box that filtered and array of objects and on my search box I used the (ngModelChange)="onChange($event)"

in my .html

<input type="text" [(ngModel)]="searchText" (ngModelChange)="reSearch(newValue)" placeholder="Search">

then in my component.ts

reSearch(newValue: string) {
    //this.searchText would equal the new value
    //handle my filtering with the new value
}

No, but you could cast the whole expression rather than the sub-components of that expression. Actually, that probably makes it less readable in this case.

display is not an attribute - it's a CSS property. You need to access the style object for this:

document.getElementById('classRight').style.display = 'none';

Use the Boost Graph Library - Python Bindings.

I'm guessing you want to center the box both vertically and horizontally, regardless of browser window size. Since you have a fixed width and height for the box, this should work:

Markup:

<div></div>

CSS:

div {
    height: 200px;
    width: 400px;
    background: black;

    position: fixed;
    top: 50%;
    left: 50%;
    margin-top: -100px;
    margin-left: -200px;
}

The div should remain in the center of the screen even if you resize the browser. Just replace the margin-top and margin-left with half of the height and width of your table.

Edit: Credit goes to CSS-Tricks, where I got the original idea.

If you're looking to reduce clutter, consider

var lst = new List<string> { "foo", "bar" };

This uses two features of C# 3.0: type inference (the var keyword) and the collection initializer for lists.

Alternatively, if you can make do with an array, this is even shorter (by a small amount):

var arr = new [] { "foo", "bar" };

Here is another way that uses the 2-element data constructor. No functions are needed to initialize it. There is no 3rd party code (Boost), no static functions or objects, no tricks, just simple C++:

#include <map>
#include <string>

typedef std::map<std::string, int> MyMap;

const MyMap::value_type rawData[] = {
   MyMap::value_type("hello", 42),
   MyMap::value_type("world", 88),
};
const int numElems = sizeof rawData / sizeof rawData[0];
MyMap myMap(rawData, rawData + numElems);

Since I wrote this answer C++11 is out. You can now directly initialize STL containers using the new initializer list feature:

const MyMap myMap = { {"hello", 42}, {"world", 88} };

You can do it by using Apache Commons IO without worrying about internal details.

Use org.apache.commons.io.FileUtils.readFileToByteArray(File file) which return data of type byte[].

MySQL stores DATETIME without timezone information. Let's say you store '2019-01-01 20:00:00' into a DATETIME field, when you retrieve that value you're expected to know what timezone it belongs to.

So in your case, when you store a value into a DATETIME field, make sure it is Tanzania time. Then when you get it out, it will be Tanzania time. Yay!

Now, the hairy question is: When I do an INSERT/UPDATE, how do I make sure the value is Tanzania time? Two cases:

1. You do INSERT INTO table (dateCreated) VALUES (CURRENT_TIMESTAMP or NOW()).

2. You do INSERT INTO table (dateCreated) VALUES (?), and specify the current time from your application code.

CASE #1

MySQL will take the current time, let's say that is '2019-01-01 20:00:00' Tanzania time. Then MySQL will convert it to UTC, which comes out to '2019-01-01 17:00:00', and store that value into the field.

So how do you get the Tanzania time, which is '20:00:00', to store into the field? It's not possible. Your code will need to expect UTC time when reading from this field.

CASE #2

It depends on what type of value you pass as ?. If you pass the string '2019-01-01 20:00:00', then good for you, that's exactly what will be stored to the DB. If you pass a Date object of some kind, then it'll depend on how the db driver interprets that Date object, and ultimate what 'YYYY-MM-DD HH:mm:ss' string it provides to MySQL for storage. The db driver's documentation should tell you.

The other answers don't work. The only way to see the captured output is using the following flag:

Okay, but you all know that the * is a wildcard and allows cross site scripting from every domain?

You would like to send multiple Access-Control-Allow-Origin headers for every site that's allowed to - but unfortunately its officially not supported to send multiple Access-Control-Allow-Origin headers, or to put in multiple origins.

You can solve this by checking the origin, and sending back that one in the header, if it is allowed:

$origin = $_SERVER['HTTP_ORIGIN'];
$allowed_domains = [
    'http://mysite1.com',
    'https://www.mysite2.com',
    'http://www.mysite2.com',
];

if (in_array($origin, $allowed_domains)) {
    header('Access-Control-Allow-Origin: ' . $origin);
}

Thats much safer. You might want to edit the matching and change it to a manual function with some regex, or something like that. At least this will only send back 1 header, and you will be sure its the one that the request came from. Please do note that all HTTP headers can be spoofed, but this header is for the client's protection. Don't protect your own data with those values. If you want to know more, read up a bit on CORS and CSRF.

Why is it safer?

Allowing access from other locations then your own trusted site allows for session highjacking. I'm going to go with a little example - image Facebook allows a wildcard origin - this means that you can make your own website somewhere, and make it fire AJAX calls (or open iframes) to facebook. This means you can grab the logged in info of the facebook of a visitor of your website. Even worse - you can script POST requests and post data on someone's facebook - just while they are browsing your website.

Be very cautious when using the ACAO headers!

After reading many resources regarding this topic, including StackOverFlow, I find that not all solutions are working properly. Below is our attempt to fix this.

Basically, We take the friendly name of an Enum from a DescriptionAttribute if it exists.
If it does not We use RegEx to determine the words within the Enum name and add spaces.

Next version, we will use another Attribute to flag whether we can/should take the friendly name from a localizable resource file.

Below are the test cases. Please report if you have another test case that do not pass.

public static class EnumHelper
{
    public static string ToDescription(Enum value)

        if (value == null)

        }

        if (!Enum.IsDefined(value.GetType(), value))
        {
            return string.Empty;
        }

        FieldInfo fieldInfo = value.GetType().GetField(value.ToString());
        if (fieldInfo != null)
        {
            DescriptionAttribute[] attributes =
                fieldInfo.GetCustomAttributes(typeof (DescriptionAttribute), false) as DescriptionAttribute[];
            if (attributes != null && attributes.Length > 0)
            {
                return attributes[0].Description;
            }
        }

        return StringHelper.ToFriendlyName(value.ToString());
    }
}

    public static bool IsNullOrWhiteSpace(string value)
    {
        return value == null || string.IsNullOrEmpty(value.Trim());
    }

    public static string ToFriendlyName(string value)
    {
        if (value == null) return string.Empty;
        if (value.Trim().Length == 0) return string.Empty;

        string result = value;

        result = string.Concat(result.Substring(0, 1).ToUpperInvariant(), result.Substring(1, result.Length - 1));

        const string pattern = @"([A-Z]+(?![a-z])|\d+|[A-Z][a-z]+|(?![A-Z])[a-z]+)+";

        List<string> words = new List<string>();

                new string[] {"Pascal123", "Pascal 123"}, 
                new string[] {"Pascal123ABC", "Pascal 123 ABC"}, 
                new string[] {"PascalABC123", "Pascal ABC 123"}, 
                new string[] {"123Pascal", "123 Pascal"}, 
                new string[] {"123ABCPascal", "123 ABC Pascal"},

        foreach (string[] givens in cases)
        {
            string input = givens[0];
            string expected = givens[1];
            string output = StringHelper.ToFriendlyName(input);

            Assert.AreEqual(expected, output);
        }
    }
}

Change your line

ws.Range(Rand, 1).EntireRow.Delete

to

ws.Cells(Rand, 1).EntireRow.Delete 

I had the same problem. I think the best solution is to use log.exception, which will automatically print out stack trace and error message, such as:

try:
    pass
    log.info('Success')
except:
    log.exception('Failed')

kramdown—the Ruby-based markdown engine that is the default for Jekyll and thus GitHub Pages—has built-in comment support through its extension syntax:

{::comment}
This text is completely ignored by kramdown - a comment in the text.
{:/comment}

Do you see {::comment}this text{:/comment}?
{::comment}some other comment{:/}

This has the benefit of allowing in-line comments, but the downside of not being portable to other Markdown engines.

The easiest way to do this is by using the built in MaskFormatter in the javax.swing.text library.

You can do something like this :

import javax.swing.text.MaskFormatter;

String phoneMask= "###-###-####";
String phoneNumber= "123423452345";

MaskFormatter maskFormatter= new MaskFormatter(phoneMask);
maskFormatter.setValueContainsLiteralCharacters(false);
maskFormatter.valueToString(phoneNumber) ;

I think that this code is going to help:

JS:

$('#foo').ready(function () {
    $('#loadingMessage').css('display', 'none');
});
$('#foo').load(function () {
    $('#loadingMessage').css('display', 'none');
});

HTML:

<iframe src="http://google.com/" id="foo"></iframe>
<div id="loadingMessage">Loading...</div>

CSS:

#loadingMessage {
    width: 100%;
    height: 100%;
    z-index: 1000;
    background: #ccc;
    top: 0px;
    left: 0px;
    position: absolute;
}

The immediate problem seems to be that you're missing the psycopg2 module.

You have to create an object. Assign the values to the object. Then push it into the array:

var nietos = [];
var obj = {};
obj["01"] = nieto.label;
obj["02"] = nieto.value;
nietos.push(obj);

Given that most recommended error mode for PDO is ERRMODE_EXCEPTION, no direct execute() result verification will ever work. As the code execution won't even reach the condition offered in other answers.

So, there are three possible scenarios to handle the query execution result in PDO:

1. To tell the success, no verification is needed. Just keep with your program flow.
2. To handle the unexpected error, keep with the same - no immediate handling code is needed. An exception will be thrown in case of a database error, and it will bubble up to the site-wide error handler that eventually will result in a common 500 error page.
3. To handle the expected error, like a duplicate primary key, and if you have a certain scenario to handle this particular error, then use a try..catch operator.

For a regular PHP user it sounds a bit alien - how's that, not to verify the direct result of the operation? - but this is exactly how exceptions work - you check the error somewhere else. Once for all. Extremely convenient.

So, in a nutshell: in a regular code you don't need any error handling at all. Just keep your code as is:

$stmt->bindParam(':field1', $field1, PDO::PARAM_STR);
$stmt->bindParam(':field2', $field2, PDO::PARAM_STR);
$stmt->execute();
echo "Success!"; // whatever

On success it will tell you so, on error it will show you the regular error page that your application is showing for such an occasion.

Only in case you have a handling scenario other than just reporting the error, put your insert statement in a try..catch operator, check whether it was the error you expected and handle it; or - if the error was any different - re-throw the exception, to make it possible to be handled by the site-wide error handler usual way. Below is the example code from my article on error handling with PDO:

try {
     $pdo->prepare("INSERT INTO users VALUES (NULL,?,?,?,?)")->execute($data);
} catch (PDOException $e) {
    if ($e->getCode() == 1062) {
        // Take some action if there is a key constraint violation, i.e. duplicate name
    } else {
        throw $e;
    }
}
echo "Success!";

In the code above we are checking for the particular error to take some action and re-throwing the exception for the any other error (no such table for example) which will be reported to a programmer.

While again - just to tell a user something like "Your insert was successful" no condition is ever needed.

Step 1: You need to defuse the node ID, until the hash has been set. This is done by removing the ID off the node while the hash is being set, and then adding it back on.

hash = hash.replace( /^#/, '' );
var node = $( '#' + hash );
if ( node.length ) {
  node.attr( 'id', '' );
}
document.location.hash = hash;
if ( node.length ) {
  node.attr( 'id', hash );
}

Step 2: Some browsers will trigger the scroll based on where the ID'd node was last seen so you need to help them a little. You need to add an extra div to the top of the viewport, set its ID to the hash, and then roll everything back:

hash = hash.replace( /^#/, '' );
var fx, node = $( '#' + hash );
if ( node.length ) {
  node.attr( 'id', '' );
  fx = $( '<div></div>' )
          .css({
              position:'absolute',
              visibility:'hidden',
              top: $(document).scrollTop() + 'px'
          })
          .attr( 'id', hash )
          .appendTo( document.body );
}
document.location.hash = hash;
if ( node.length ) {
  fx.remove();
  node.attr( 'id', hash );
}

Step 3: Wrap it in a plugin and use that instead of writing to location.hash...

Add session_start(); before !Doctype Declaration

    <?php session_start(); ?>
    <!doctype html>
    <html>
    <body>
<?php 
if (isset($_SESSION['LAST_ACTIVITY']) && (time() - $_SESSION['LAST_ACTIVITY'] > 1800)) 
{   
    session_destroy();   
    session_unset();     
} 
?>
</body>
</html>

plz change %HTTPPORT% as 8080 its working for me

there are lots of compression methods that work recursively command line and its good to know who the end audience is.

i.e. if it is to be sent to someone running windows then zip would probably be best:

zip -r file.zip folder_to_zip

unzip filenname.zip

for other linux users or your self tar is great

tar -cvzf filename.tar.gz folder

tar -cvjf filename.tar.bz2 folder  # even more compression

#change the -c to -x to above to extract

One must be careful with tar and how things are tarred up/extracted, for example if I run

cd ~
tar -cvzf passwd.tar.gz /etc/passwd
tar: Removing leading `/' from member names
/etc/passwd


pwd

/home/myusername

tar -xvzf passwd.tar.gz

this will create /home/myusername/etc/passwd

unsure if all versions of tar do this:

 Removing leading `/' from member names

toString is a function, not a property. You'll want this:

console.log(aa.toString());

Alternatively, use join to specify the separator (toString() === join(','))

console.log(aa.join(' and '));

I had similar error with two foreign keys for different tables but with same key names! I have renamed keys and the error had gone)

You can use the path module to join the path of the directory in which helper1.js lives to the relative path of foobar.json. This will give you the absolute path to foobar.json.

var fs = require('fs');
var path = require('path');

var jsonPath = path.join(__dirname, '..', 'config', 'dev', 'foobar.json');
var jsonString = fs.readFileSync(jsonPath, 'utf8');

This should work on Linux, OSX, and Windows assuming a UTF8 encoding.

OOXML files like those that come from Excel 2007 are encoded in UTF-8, according to wikipedia. I don't know about CSV files, but it stands to reason it would use the same format...

I would think that one reason could be that the color is applied to things other than font. For example:

div {
    border: 1px solid;
    color: red;
}

Yields both a red font color and a red border.

Alternatively, it could just be that the W3C's CSS standards are completely backwards and nonsensical as evidenced elsewhere.

In the Manifest, you can set the screenOrientation to landscape. It would look something like this in the XML:

<activity android:name="MyActivity"
android:screenOrientation="landscape"
android:configChanges="keyboardHidden|orientation|screenSize">
...
</activity>

Where MyActivity is the one you want to stay in landscape.

The android:configChanges=... line prevents onResume(), onPause() from being called when the screen is rotated. Without this line, the rotation will stay as you requested but the calls will still be made.

Note: keyboardHidden and orientation are required for < Android 3.2 (API level 13), and all three options are required 3.2 or above, not just orientation.

Or one can simply use: $('#myElem').valid()

if ($('#myElem').valid()){
   // will also trigger unobtrusive validation only for this element if in place 
   // add your extra logic here to execute only when element is valid
}

Note that validate() needs to be called on the form before checking it using this method.

Documentation link: https://jqueryvalidation.org/valid/

Simply. You can go to 'File -> Preferences -> Color Theme' option in visual studio and change the color of you choice.

Generally you would use the exit() method with an appropriate exit status.

Zero would mean a successful run. A non-zero status indicates some sort of problem has occurred. This exit code is used by parent processes (e.g. shell scripts) to determine if a process has run successfully.

git checkout accepts an --ours or --theirs option for cases like this. So if you have a merge conflict, and you know you just want the file from the branch you are merging in, you can do:

$ git checkout --theirs -- path/to/conflicted-file.txt

to use that version of the file. Likewise, if you know you want your version (not the one being merged in) you can use

$ git checkout --ours -- path/to/conflicted-file.txt

I have to agree with the comments above, that you can't call a file, but you could load a JS file like this, I'm unsure if it answers your question but it may help... oh and I've used a link instead of a button in my example...

<a href='linkhref.html' id='mylink'>click me</a>

<script type="text/javascript">

var myLink = document.getElementById('mylink');

myLink.onclick = function(){

    var script = document.createElement("script");
    script.type = "text/javascript";
    script.src = "Public/Scripts/filename.js."; 
    document.getElementsByTagName("head")[0].appendChild(script);
    return false;

}


</script>

From documentation: https://docs.djangoproject.com/en/1.10/ref/settings/

if DEBUG is False, you also need to properly set the ALLOWED_HOSTS setting. Failing to do so will result in all requests being returned as “Bad Request (400)”.

And from here: https://docs.djangoproject.com/en/1.10/ref/settings/#std:setting-ALLOWED_HOSTS

I am using something like this:

ALLOWED_HOSTS = ['localhost', '127.0.0.1', 'www.mysite.com']

You can chain .fail() callback for error response.

$.get('http://example.com/page/2/', function(data){ 
   $(data).find('#reviews .card').appendTo('#reviews');
})
.fail(function() {
  //Error logic
})

var myNode = document.getElementById("foo");
var fc = myNode.firstChild;

while( fc ) {
    myNode.removeChild( fc );
    fc = myNode.firstChild;
}

If there's any chance that you have jQuery affected descendants, then you must use some method that will clean up jQuery data.

$('#foo').empty();

The jQuery .empty() method will ensure that any data that jQuery associated with elements being removed will be cleaned up.

If you simply use DOM methods of removing the children, that data will remain.

You CAN do this if you are willing to "frig" it a little by making a variable of the static class and assigning it to null. However, this method would not be available to static calls on the class, so not sure how much use it would be:

Console myConsole = null;
myConsole.WriteBlueLine("my blue line");

public static class Helpers {
    public static void WriteBlueLine(this Console c, string text)
    {
        Console.ForegroundColor = ConsoleColor.Blue;
        Console.WriteLine(text);
        Console.ResetColor();
    }
}

It seems that one of the most common reasons this happens is if you install a new version of PostgreSQL without stopping the service of an existing installation. This was a particular headache of mine, too. Before installing or upgrading, particularly on OS X and using the one click installer from Enterprise DB, make sure you check the status of the old installation before proceeding.

You should be able to just check out the one file you want to restore. Try something like svn co svn://your_repos/path/to/file/you/want/to/restore@rev where rev is the last revision at which the file existed.

I had to do exactly this a little while ago and if I remember correctly, using the -r option to svn didn't work; I had to use the :rev syntax. (Although I might have remembered it backwards...)

Since SQL tag is attached to the question I really think all answers missed one major point.

MODIFY command does not exist in SQL server So you will be getting an error when you run the

ALTER TABLE Satellites MODIFY COLUMN SatelliteID INT auto_increment PRIMARY KEY;

In this case you can either add new column as INT IDENTITY

ALTER TABLE Satellites
   ADD ID INT IDENTITY
       CONSTRAINT PK_YourTable PRIMARY KEY CLUSTERED;

OR

DECLARE @id INT
SET @id = 0 
UPDATE Satellites SET @id = SatelliteID = @id + 1 

Clearly, there is no perfect answer. However, if you want to allow the user to

1. select certain cells
2. allow them to change those cells, and
3. trap each click,even repeated clicks on the same cell,

then the easiest way seems to be to move the focus off the selected cell, so that clicking it will trigger a Select event.

One option is to move the focus as I suggested above, but this prevents cell editing. Another option is to extend the selection by one cell (left/right/up/down),because this permits editing of the original cell, but will trigger a Select event if that cell is clicked again on its own.

If you only wanted to trap selection of a single column of cells, you could insert a hidden column to the right, extend the selection to include the hidden cell to the right when the user clicked,and this gives you an editable cell which can be trapped every time it is clicked. The code is as follows

Private Sub Worksheet_SelectionChange(ByVal Target As Range)
  'prevent Select event triggering again when we extend the selection below
  Application.EnableEvents = False
  Target.Resize(1, 2).Select
  Application.EnableEvents = True
End Sub

By using ''.join

list1 = ['1', '2', '3']
str1 = ''.join(list1)

Or if the list is of integers, convert the elements before joining them.

list1 = [1, 2, 3]
str1 = ''.join(str(e) for e in list1)

$(element).click(function(){
    window.close();
});

Note: you can not close any window that you didn't opened with window.open. Directly invoking window.close() will ask user with a dialogue box.

well i found a solution to this problem for who want to work with xCode 4. All what you have to do is importing frameworks from the SimulatorSDK folder /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator4.3.sdk/System/Library/Frameworks

i don't know if it works when you try to test your app on a real iDevice, but i'm sure that it works on simulator.

Use this to get the time in milliseconds (long)(NSTimeInterval)([[NSDate date] timeIntervalSince1970]).

Create id column in your data frame or use any column name to identify the row. Using index is not fair to delete.

Use subset function to create new frame.

updated_myData <- subset(myData, id!= 6)
print (updated_myData)

updated_myData <- subset(myData, id %in% c(1, 3, 5, 7))
print (updated_myData)

Changing the Target Framework in project properties from .NET Framework 4.7.1 to 4.6.2 worked for me.

The files need to be in a JPEG or PNG format of 24 bits, in a 2:1 ratio if it is a portrait and a 16:9 ratio for landscapes. Be careful that if you go for different sizes: the maximum size should not be more than twice bigger than the minimum size.

You can use the asList method with varargs to do this in one line:

java.util.Arrays.asList('+', '-', '*', '^');

If the list does not need to be modified further then this would already be enough. Otherwise you can pass it to the ArrayList constructor to create a mutable list:

new ArrayList(Arrays.asList('+', '-', '*', '^'));

The fleqn option in the document class will apply left aligning setting in all equations of the document. You can instead use \begin{flalign}. This will align only the desired equations.

you may use the below code it works fine with swift 3

var preferredLanguage : String = Bundle.main.preferredLocalizations.first!

Replace the iframe for this:

<video class="video-fluid z-depth-1" loop controls muted>
  <source src="videos/example.mp4" type="video/mp4" />
</video>

Installation

OpCache is compiled by default on PHP5.5+. However it is disabled by default. In order to start using OpCache in PHP5.5+ you will first have to enable it. To do this you would have to do the following.

Add the following line to your php.ini:

zend_extension=/full/path/to/opcache.so (nix)
zend_extension=C:\path\to\php_opcache.dll (win)

Note that when the path contains spaces you should wrap it in quotes:

zend_extension="C:\Program Files\PHP5.5\ext\php_opcache.dll"

Also note that you will have to use the zend_extension directive instead of the "normal" extension directive because it affects the actual Zend engine (i.e. the thing that runs PHP).

Usage

Currently there are four functions which you can use:

opcache_get_configuration():

Returns an array containing the currently used configuration OpCache uses. This includes all ini settings as well as version information and blacklisted files.

var_dump(opcache_get_configuration());

opcache_get_status():

This will return an array with information about the current status of the cache. This information will include things like: the state the cache is in (enabled, restarting, full etc), the memory usage, hits, misses and some more useful information. It will also contain the cached scripts.

var_dump(opcache_get_status());

opcache_reset():

Resets the entire cache. Meaning all possible cached scripts will be parsed again on the next visit.

opcache_reset();

opcache_invalidate():

Invalidates a specific cached script. Meaning the script will be parsed again on the next visit.

opcache_invalidate('/path/to/script/to/invalidate.php', true);

Maintenance and reports

There are some GUI's created to help maintain OpCache and generate useful reports. These tools leverage the above functions.

In your particular situation (all procedures has the same columns except 1 which has additional 1 column), it will be better and faster to check reader. FieldCount property to distinguish between them.

const int NormalColCount=.....
if(reader.FieldCount > NormalColCount)
{
// Do something special
}

I know it is an old post but I decided to answer to help other in the same situation. you can also (for performance reason) mix this solution with the solution iterating solution.

In older versions of jquery you'll have to do it the "javascript way" using settimeout

setTimeout( function(){$('div').hide();} , 4000);

or

setTimeout( "$('div').hide();", 4000);

Recently with jquery 1.4 this solution has been added:

$("div").delay(4000).hide();

Of course replace "div" by the correct element using a valid jquery selector and call the function when the document is ready.

GregorianCalendar c = GregorianCalendar.from((LocalDate.parse("2016-06-22")).atStartOfDay(ZoneId.systemDefault()));
XMLGregorianCalendar date2 = DatatypeFactory.newInstance().newXMLGregorianCalendar(c);

This is pretty basic, just put in the php file you want to use for processing in the element.

For example

<form action="process.php" method="post">

Then in process.php you would get the form values using $_POST['name of the variable]

I have expanded the method with font as a parameter:

public static void AppendText(this RichTextBox box, string text, Color color, Font font)
{
    box.SelectionStart = box.TextLength;
    box.SelectionLength = 0;

    box.SelectionColor = color;
    box.SelectionFont = font;
    box.AppendText(text);
    box.SelectionColor = box.ForeColor;
}

If you're using Laravel, do

composer update

This should be work.

You have to install npm install env-cmd

Make .env in the root directory and update like this & REACT_APP_ is the compulsory prefix for the variable name.

REACT_APP_NODE_ENV="production"
REACT_APP_DB="http://localhost:5000"

Update package.json

  "scripts": {
    "start": "env-cmd react-scripts start",
    "build": "env-cmd react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  }

This is the best method for select text in dropdownlist.

$("#dropdownid option:contains(your selected text)").attr('selected', true);

It is easy you need to echo the value you need to return and then capture it like below

demofunc(){
    local variable="hellow"
    echo $variable    
}

val=$(demofunc)
echo $val

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

And then install wget with brew and also enable openressl for TLS support

brew install wget --with-libressl

It worked perfectly for me.

In my case it failed to fetch be.archives.ubuntu.com (Belgium) so I generated a new sources.plist on this link as recommended by the accepted answer.

The thing that solved it for me was just to change the country to United States when generating the sources.plist. Then I could run this again.

apt-get update

Simple solution: add this header to the response:

Cache-control: no-store

Why this works is clearly explained at this authoritative page: https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Cache-Control

It also explains why no-cache does not work.

Other answers do not work because:

Caching.delete is about a new cache that you may create for off-line work, see: https://web.dev/cache-api-quick-guide/

Fragments using a # in the URL do not work because the # tells the browser to not send a request to the server.

A cache-buster with a random part added to the url works, but will also fill the browser cache. In my app, I wanted to download a 5 MB picture every few seconds from a web cam. It will take just an hour or less to completely freeze your pc. I still don't know why the browser cache is not limited to a reasonable max, but this is definitely a disadvantage.

Based on usage should use this get method.

Example1

In [14]: user_dict = {'type': False}

In [15]: user_dict.get('type', '')

Out[15]: False

In [16]: user_dict.get('type') or ''

Out[16]: ''

Example2

In [17]: user_dict = {'type': "lead"}

In [18]: user_dict.get('type') or ''

Out[18]: 'lead'

In [19]: user_dict.get('type', '')

Out[19]: 'lead'

I'm adding this answer because none of the others worked for me.

I had to add a Header Handler to the Proxy:

import java.util.Set;
import java.util.TreeSet;

import javax.xml.namespace.QName;
import javax.xml.soap.SOAPElement;
import javax.xml.soap.SOAPEnvelope;
import javax.xml.soap.SOAPFactory;
import javax.xml.soap.SOAPHeader;
import javax.xml.ws.handler.MessageContext;
import javax.xml.ws.handler.soap.SOAPHandler;
import javax.xml.ws.handler.soap.SOAPMessageContext;

public class SOAPHeaderHandler implements SOAPHandler<SOAPMessageContext> {

    private final String authenticatedToken;

    public SOAPHeaderHandler(String authenticatedToken) {
        this.authenticatedToken = authenticatedToken;
    }

    public boolean handleMessage(SOAPMessageContext context) {
        Boolean outboundProperty =
                (Boolean) context.get(MessageContext.MESSAGE_OUTBOUND_PROPERTY);
        if (outboundProperty.booleanValue()) {
            try {
                SOAPEnvelope envelope = context.getMessage().getSOAPPart().getEnvelope();
                SOAPFactory factory = SOAPFactory.newInstance();
                String prefix = "urn";
                String uri = "urn:xxxx";
                SOAPElement securityElem =
                        factory.createElement("Element", prefix, uri);
                SOAPElement tokenElem =
                        factory.createElement("Element2", prefix, uri);
                tokenElem.addTextNode(authenticatedToken);
                securityElem.addChildElement(tokenElem);
                SOAPHeader header = envelope.addHeader();
                header.addChildElement(securityElem);
            } catch (Exception e) {
                e.printStackTrace();
            }
        } else {
            // inbound
        }
        return true;
    }

    public Set<QName> getHeaders() {
        return new TreeSet();
    }

    public boolean handleFault(SOAPMessageContext context) {
        return false;
    }

    public void close(MessageContext context) {
        //
    }
}

In the proxy, I just add the Handler:

BindingProvider bp =(BindingProvider)basicHttpBindingAuthentication;
bp.getBinding().getHandlerChain().add(new SOAPHeaderHandler(authenticatedToken));
bp.getBinding().getHandlerChain().add(new SOAPLoggingHandler());

Simply create a Class Name and define your style there like this :

table.tdfont td {
  font-size: 0.9em;
}

declare @date datetime;
set @date = getdate(); -- or some date
select dateadd(month,1+datediff(month,0,@date),-1);

If the script creates any variables or functions in the global space you can check for their existance:

External JS (in global scope) --

var myCustomFlag = true;

And to check if this has run:

if (typeof window.myCustomFlag == 'undefined') {
    //the flag was not found, so the code has not run
    $.getScript('<external JS>');
}

Update

You can check for the existence of the <script> tag in question by selecting all of the <script> elements and checking their src attributes:

//get the number of `<script>` elements that have the correct `src` attribute
var len = $('script').filter(function () {
    return ($(this).attr('src') == '<external JS>');
}).length;

//if there are no scripts that match, the load it
if (len === 0) {
    $.getScript('<external JS>');
}

Or you can just bake this .filter() functionality right into the selector:

var len = $('script[src="<external JS>"]').length;

You can use float on that particular div, e.g.

<div style="float:right;">

Float the div you want more space to have to the left as well:

<div style="float:left;">

If all else fails give the div on the right position:absolute and then move it as right as you want it to be.

<div style="position:absolute; left:-500px; top:30px;"> 

etc. Obviously put the style in a seperate stylesheet but this is just a quicker example.

Make sure you're on the main thread.

If not, it will still save the button text. It will be there when you inspect the object in the debugger. But it won't actually update the view.

Note: This answer is a pure Gradle answer, I use this in IntelliJ on a regular basis but I don't know how the integration is with Android Studio. I am a believer in knowing what is going on for me, so this is how I use Gradle and Android.

TL;DR Full Example - https://github.com/ethankhall/driving-time-tracker/

Disclaimer: This is a project I am/was working on.

Gradle has a defined structure ( that you can change, link at the bottom tells you how ) that is very similar to Maven if you have ever used it.

Project Root
+-- src
|   +-- main (your project)
|   |   +-- java (where your java code goes)
|   |   +-- res  (where your res go)
|   |   +-- assets (where your assets go)
|   |   \-- AndroidManifest.xml
|   \-- instrumentTest (test project)
|       \-- java (where your java code goes)
+-- build.gradle
\-- settings.gradle

If you only have the one project, the settings.gradle file isn't needed. However you want to add more projects, so we need it.

Now let's take a peek at that build.gradle file. You are going to need this in it (to add the android tools)

build.gradle

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.3'
    }
}

Now we need to tell Gradle about some of the Android parts. It's pretty simple. A basic one (that works in most of my cases) looks like the following. I have a comment in this block, it will allow me to specify the version name and code when generating the APK.

build.gradle

apply plugin: "android"
android {
        compileSdkVersion 17
        /*
        defaultConfig {
            versionCode = 1
            versionName = "0.0.0"
        }
        */
    }

Something we are going to want to add, to help out anyone that hasn't seen the light of Gradle yet, a way for them to use the project without installing it.

build.gradle

task wrapper(type: org.gradle.api.tasks.wrapper.Wrapper) {
    gradleVersion = '1.4'
}

So now we have one project to build. Now we are going to add the others. I put them in a directory, maybe call it deps, or subProjects. It doesn't really matter, but you will need to know where you put it. To tell Gradle where the projects are you are going to need to add them to the settings.gradle.

Directory Structure:

Project Root
+-- src (see above)
+-- subProjects (where projects are held)
|   +-- reallyCoolProject1 (your first included project)
|       \-- See project structure for a normal app
|   \-- reallyCoolProject2 (your second included project)
|       \-- See project structure for a normal app
+-- build.gradle
\-- settings.gradle

settings.gradle:

include ':subProjects:reallyCoolProject1'
include ':subProjects:reallyCoolProject2'

The last thing you should make sure of is the subProjects/reallyCoolProject1/build.gradle has apply plugin: "android-library" instead of apply plugin: "android".

Like every Gradle project (and Maven) we now need to tell the root project about it's dependency. This can also include any normal Java dependencies that you want.

build.gradle

dependencies{
    compile 'com.fasterxml.jackson.core:jackson-core:2.1.4'
    compile 'com.fasterxml.jackson.core:jackson-databind:2.1.4'
    compile project(":subProjects:reallyCoolProject1")
    compile project(':subProjects:reallyCoolProject2')
}

I know this seems like a lot of steps, but they are pretty easy once you do it once or twice. This way will also allow you to build on a CI server assuming you have the Android SDK installed there.

NDK Side Note: If you are going to use the NDK you are going to need something like below. Example build.gradle file can be found here: https://gist.github.com/khernyo/4226923

build.gradle

task copyNativeLibs(type: Copy) {
    from fileTree(dir: 'libs', include: '**/*.so' )  into  'build/native-libs'
}
tasks.withType(Compile) { compileTask -> compileTask.dependsOn copyNativeLibs }

clean.dependsOn 'cleanCopyNativeLibs'

tasks.withType(com.android.build.gradle.tasks.PackageApplication) { pkgTask ->
  pkgTask.jniDir new File('build/native-libs')
}

Ahhhh, now it is clear. You seem to have problems binding back the value. Not with displaying it on the view. Indeed, that's the fault of the default model binder. You could write and use a custom one that will take into consideration the [DisplayFormat] attribute on your model. I have illustrated such a custom model binder here: https://stackoverflow.com/a/7836093/29407

Apparently some problems still persist. Here's my full setup working perfectly fine on both ASP.NET MVC 3 & 4 RC.

Model:

public class MyViewModel
{
    [DisplayName("date of birth")]
    [DataType(DataType.Date)]
    [DisplayFormat(DataFormatString = "{0:dd/MM/yyyy}", ApplyFormatInEditMode = true)]
    public DateTime? Birth { get; set; }
}

Controller:

public class HomeController : Controller
{
    public ActionResult Index()
    {
        return View(new MyViewModel
        {
            Birth = DateTime.Now
        });
    }

    [HttpPost]
    public ActionResult Index(MyViewModel model)
    {
        return View(model);
    }
}

View:

@model MyViewModel

@using (Html.BeginForm())
{
    @Html.LabelFor(x => x.Birth)
    @Html.EditorFor(x => x.Birth)
    @Html.ValidationMessageFor(x => x.Birth)
    <button type="submit">OK</button>
}

Registration of the custom model binder in Application_Start:

ModelBinders.Binders.Add(typeof(DateTime?), new MyDateTimeModelBinder());

And the custom model binder itself:

public class MyDateTimeModelBinder : DefaultModelBinder
{
    public override object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext)
    {
        var displayFormat = bindingContext.ModelMetadata.DisplayFormatString;
        var value = bindingContext.ValueProvider.GetValue(bindingContext.ModelName);

        if (!string.IsNullOrEmpty(displayFormat) && value != null)
        {
            DateTime date;
            displayFormat = displayFormat.Replace("{0:", string.Empty).Replace("}", string.Empty);
            // use the format specified in the DisplayFormat attribute to parse the date
            if (DateTime.TryParseExact(value.AttemptedValue, displayFormat, CultureInfo.InvariantCulture, DateTimeStyles.None, out date))
            {
                return date;
            }
            else
            {
                bindingContext.ModelState.AddModelError(
                    bindingContext.ModelName,
                    string.Format("{0} is an invalid date format", value.AttemptedValue)
                );
            }
        }

        return base.BindModel(controllerContext, bindingContext);
    }
}

Now, no matter what culture you have setup in your web.config (<globalization> element) or the current thread culture, the custom model binder will use the DisplayFormat attribute's date format when parsing nullable dates.

The simplest and cleanest pre-ECMAScript-6 solution (which is also sufficiently robust to return false even if a non-numeric value such as a string or null is passed to the function) would be the following:

function isInteger(x) { return (x^0) === x; } 

The following solution would also work, although not as elegant as the one above:

function isInteger(x) { return Math.round(x) === x; }

Note that Math.ceil() or Math.floor() could be used equally well (instead of Math.round()) in the above implementation.

Or alternatively:

function isInteger(x) { return (typeof x === 'number') && (x % 1 === 0); }

One fairly common incorrect solution is the following:

function isInteger(x) { return parseInt(x, 10) === x; }

While this parseInt-based approach will work well for many values of x, once x becomes quite large, it will fail to work properly. The problem is that parseInt() coerces its first parameter to a string before parsing digits. Therefore, once the number becomes sufficiently large, its string representation will be presented in exponential form (e.g., 1e+21). Accordingly, parseInt() will then try to parse 1e+21, but will stop parsing when it reaches the e character and will therefore return a value of 1. Observe:

> String(1000000000000000000000)
'1e+21'

> parseInt(1000000000000000000000, 10)
1

> parseInt(1000000000000000000000, 10) === 1000000000000000000000
false

I was lazy and added the loops

import java.util.Arrays;


public class Sort {
    public static void main(String args[])
    {
        int [] array = new int[10];
        for ( int i = 0 ; i < array.length ; i++ ) {
            array[i] = ((int)(Math.random()*100+1));
        }
        Arrays.sort( array );
        for ( int i = 0 ; i < array.length ; i++ ) {
            System.out.println(array[i]);
        }
    }
}

Your array has a length of 10. You need one variable (i) which takes the values from 0to 9.

for ( int i = 0  ; i < array.length ;   i++ ) 
       ^               ^                   ^
       |               |                   ------  increment ( i = i + 1 )
       |               |
       |               +-------------------------- repeat as long i < 10
       +------------------------------------------ start value of i


Arrays.sort( array );

Is a library methods that sorts arrays.

Should I put the shebang in my Python scripts?

Put a shebang into a Python script to indicate:

• this module can be run as a script
• whether it can be run only on python2, python3 or is it Python 2/3 compatible
• on POSIX, it is necessary if you want to run the script directly without invoking python executable explicitly

Are these equally portable? Which form is used most?

If you write a shebang manually then always use #!/usr/bin/env python unless you have a specific reason not to use it. This form is understood even on Windows (Python launcher).

Note: installed scripts should use a specific python executable e.g., /usr/bin/python or /home/me/.virtualenvs/project/bin/python. It is bad if some tool breaks if you activate a virtualenv in your shell. Luckily, the correct shebang is created automatically in most cases by setuptools or your distribution package tools (on Windows, setuptools can generate wrapper .exe scripts automatically).

In other words, if the script is in a source checkout then you will probably see #!/usr/bin/env python. If it is installed then the shebang is a path to a specific python executable such as #!/usr/local/bin/python (NOTE: you should not write the paths from the latter category manually).

To choose whether you should use python, python2, or python3 in the shebang, see PEP 394 - The "python" Command on Unix-Like Systems:

• ... python should be used in the shebang line only for scripts that are source compatible with both Python 2 and 3.

• in preparation for an eventual change in the default version of Python, Python 2 only scripts should either be updated to be source compatible with Python 3 or else to use python2 in the shebang line.

Simply using below code in Kotlin works for me

WebView(applicationContext).clearCache(true)

in Bootstrap 3 class="affix" works, but in Bootstrap 4 it does not. I solved this problem in Bootstrap 4 with class="sticky-top" (using position: fixed in CSS has its own problems)

code will be something like this:

<div class="row">
    <div class="col-lg-3">
        <div class="sticky-top">
            Fixed content
        </div>
    </div>
    <div class="col-lg-9">
        Normal scrollable content
    </div>
</div>

I came up with 4 methods to achieve the results. Here is demo

Method 1:

#a {
    margin-right: auto;
}

Method 2:

#a {
    flex-grow: 1;
}

Method 3:

#b {
    margin-left: auto;
}

Method 4:

#container {
    justify-content: space-between;
}

<content>(?:[^\n]*(\n+))+</content>

Whilst you certainly can use MySQL's IF() control flow function as demonstrated by dbemerlin's answer, I suspect it might be a little clearer to the reader (i.e. yourself, and any future developers who might pick up your code in the future) to use a CASE expression instead:

UPDATE Table
SET    A = CASE
         WHEN A > 0 AND A < 1 THEN 1
         WHEN A > 1 AND A < 2 THEN 2
         ELSE A
       END
WHERE  A IS NOT NULL

Of course, in this specific example it's a little wasteful to set A to itself in the ELSE clause—better entirely to filter such conditions from the UPDATE, via the WHERE clause:

UPDATE Table
SET    A = CASE
         WHEN A > 0 AND A < 1 THEN 1
         WHEN A > 1 AND A < 2 THEN 2
       END
WHERE  (A > 0 AND A < 1) OR (A > 1 AND A < 2)

(The inequalities entail A IS NOT NULL).

Or, if you want the intervals to be closed rather than open (note that this would set values of 0 to 1—if that is undesirable, one could explicitly filter such cases in the WHERE clause, or else add a higher precedence WHEN condition):

UPDATE Table
SET    A = CASE
         WHEN A BETWEEN 0 AND 1 THEN 1
         WHEN A BETWEEN 1 AND 2 THEN 2
       END
WHERE  A BETWEEN 0 AND 2

Though, as dbmerlin also pointed out, for this specific situation you could consider using CEIL() instead:

UPDATE Table SET A = CEIL(A) WHERE A BETWEEN 0 AND 2

To summarize an attribute accessor aka attr_accessor gives you two free methods.

Like in Java they get called getters and setters.

Many answers have shown good examples so I'm just going to be brief.

#the_attribute

and

#the_attribute=

In the old ruby docs a hash tag # means a method. It could also include a class name prefix... MyClass#my_method

To add to Ivo Wetzel's answer

There seems to be a shorthand syntax for exports ? this that I can only find documented/mentioned on a Google group posting.

I.e. in a web page to make a function available globally you declare the function again with an @ prefix:

<script type="text/coffeescript">
    @aglobalfunction = aglobalfunction = () ->
         alert "Hello!"
</script>

<a href="javascript:aglobalfunction()" >Click me!</a>

Here's a stdlib solution that supports a variable utc offset in the input time string:

>>> from email.utils import parsedate_tz, mktime_tz
>>> from datetime import datetime, timedelta
>>> timestamp = mktime_tz(parsedate_tz('Tue May 08 15:14:45 +0800 2012'))
>>> utc_time = datetime(1970, 1, 1) + timedelta(seconds=timestamp)
>>> utc_time
datetime.datetime(2012, 5, 8, 7, 14, 45)

Datepicker is not part of jQuery. You have to get jQuery UI to use the datepicker.

The problem is that you're calling List<T>.Reverse() which returns void.

You could either do:

List<string> names = "Tom,Scott,Bob".Split(',').ToList<string>();
names.Reverse();

or:

IList<string> names = "Tom,Scott,Bob".Split(',').Reverse().ToList<string>();

The latter is more expensive, as reversing an arbitrary IEnumerable<T> involves buffering all of the data and then yielding it all - whereas List<T> can do all the reversing "in-place". (The difference here is that it's calling the Enumerable.Reverse<T>() extension method, instead of the List<T>.Reverse() instance method.)

More efficient yet, you could use:

string[] namesArray = "Tom,Scott,Bob".Split(',');
List<string> namesList = new List<string>(namesArray.Length);
namesList.AddRange(namesArray);
namesList.Reverse();

This avoids creating any buffers of an inappropriate size - at the cost of taking four statements where one will do... As ever, weigh up readability against performance in the real use case.

Quoting https://web.archive.org/web/20140227201242/http://v1.dione.zcu.cz/java/docs/jndi-1.2/tutorial/beyond/misc/policy.html

At the root context of the namespace is a binding with the name "comp", which is bound to a subtree reserved for component-related bindings. The name "comp" is short for component. There are no other bindings at the root context. However, the root context is reserved for the future expansion of the policy, specifically for naming resources that are tied not to the component itself but to other types of entities such as users or departments. For example, future policies might allow you to name users and organizations/departments by using names such as "java:user/alice" and "java:org/engineering".

In the "comp" context, there are two bindings: "env" and "UserTransaction". The name "env" is bound to a subtree that is reserved for the component's environment-related bindings, as defined by its deployment descriptor. "env" is short for environment. The J2EE recommends (but does not require) the following structure for the "env" namespace.

So the binding you did from spring or, for example, from a tomcat context descriptor go by default under java:comp/env/

For example, if your configuration is:

<bean id="someId" class="org.springframework.jndi.JndiObjectFactoryBean">
  <property name="jndiName" value="foo"/>
</bean>

Then you can access it directly using:

Context ctx = new InitialContext();
DataSource ds = (DataSource)ctx.lookup("java:comp/env/foo");

or you could make an intermediate step so you don't have to specify "java:comp/env" for every resource you retrieve:

Context ctx = new InitialContext();
Context envCtx = (Context)ctx.lookup("java:comp/env");
DataSource ds = (DataSource)envCtx.lookup("foo");

I just want to point out that most of the answers here don't work, I am new to NodeJS and IDK if throughout time the "module.exports.yourClass" method changed, or if people just entered the wrong answer.

// MyClass

module.exports.Ninja = class Ninja{
    test(){
        console.log('TESTING 1... 2... 3...');
    };
}

//Using MyClass in seprate File


const ninjaFw = require('./NinjaFw');

let ninja = new ninjaFw.Ninja();
ninja.test();

• This is the method I am currently using. I like this syntax, becuase module.exports sits on the same line as the class declaration and that cleans the code up a little imo. The other way you can do it is like this:

//  Ninja Framework File


class Ninja{
    test(){
        console.log('TESTING 1... 2... 3...');
    };
}


module.exports.Ninja = Ninja;

• Two different syntax but, in the end, the same result. Just a matter of syntax anesthetics.

Instead of naming my invoking class, I started using the following:

private static readonly ILog log = LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);

In this way, I can use the same line of code in every class that uses log4net without having to remember to change code when I copy and paste. Alternatively, i could create a logging class, and have every other class inherit from my logging class.

Here is a more reliable version:

class D(object):
    def __init__(self):
        self.test = 20
        self.test2 = 21
    def __getattribute__(self, name):
        if name == 'test':
            return 0.
        else:
            return super(D, self).__getattribute__(name)

It calls __getattribute__ method from parent class, eventually falling back to object.__getattribute__ method if other ancestors don't override it.

while IFS='=' read -r name value ; do
    # Print line if found variable
    sed -n '/${'"${name}"'}/p' docker-compose.yml
    # Replace variable with value. 
    sed -i 's|${'"${name}"'}|'"${value}"'|' docker-compose.yml
done < <(env)

Note: Variable name or value should not contain "|", because it is used as a delimiter.

Have a look at OpenJDK. It is the standard JVM implementation on Linux.

you can use .parseXML

var xml='<Pages>
          <Page Name="test">
           <controls>
              <test>this is a test.</test>
           </controls>  
          </Page>
          <page Name = "User">
           <controls>
             <name>Sunil</name>
           </controls>
          </page>
        </Pages>';

jquery

    xmlDoc = $.parseXML( xml ),
    $xml = $( xmlDoc );
    $($xml).each(function(){
       alert($(this).find("Page[Name]>controls>name").text());
     });

The -m switch of PuTTY takes a path to a script file as an argument, not a command.

Reference: https://the.earth.li/~sgtatham/putty/latest/htmldoc/Chapter3.html#using-cmdline-m

So you have to save your command (command_run) to a plain text file (e.g. c:\path\command.txt) and pass that to PuTTY:

putty.exe -ssh user@host -pw password -m c:\path\command.txt

Though note that you should use Plink (a command-line connection tool from PuTTY suite). It's a console application, so you can redirect its output to a file (what you cannot do with PuTTY).

A command-line syntax is identical, an output redirection added:

plink.exe -ssh user@host -pw password -m c:\path\command.txt > output.txt

See Using the command-line connection tool Plink.

And with Plink, you can actually provide the command directly on its command-line:

plink.exe -ssh user@host -pw password command > output.txt

Gory details

A DLL uses the PE executable format, and it's not too tricky to read that information out of the file.

See this MSDN article on the PE File Format for an overview. You need to read the MS-DOS header, then read the IMAGE_NT_HEADERS structure. This contains the IMAGE_FILE_HEADER structure which contains the info you need in the Machine member which contains one of the following values

• IMAGE_FILE_MACHINE_I386 (0x014c)
• IMAGE_FILE_MACHINE_IA64 (0x0200)
• IMAGE_FILE_MACHINE_AMD64 (0x8664)

This information should be at a fixed offset in the file, but I'd still recommend traversing the file and checking the signature of the MS-DOS header and the IMAGE_NT_HEADERS to be sure you cope with any future changes.

Use ImageHelp to read the headers...

You can also use the ImageHelp API to do this - load the DLL with LoadImage and you'll get a LOADED_IMAGE structure which will contain a pointer to an IMAGE_NT_HEADERS structure. Deallocate the LOADED_IMAGE with ImageUnload.

...or adapt this rough Perl script

Here's rough Perl script which gets the job done. It checks the file has a DOS header, then reads the PE offset from the IMAGE_DOS_HEADER 60 bytes into the file.

It then seeks to the start of the PE part, reads the signature and checks it, and then extracts the value we're interested in.

#!/usr/bin/perl
#
# usage: petype <exefile>
#
$exe = $ARGV[0];

open(EXE, $exe) or die "can't open $exe: $!";
binmode(EXE);
if (read(EXE, $doshdr, 64)) {

   ($magic,$skip,$offset)=unpack('a2a58l', $doshdr);
   die("Not an executable") if ($magic ne 'MZ');

   seek(EXE,$offset,SEEK_SET);
   if (read(EXE, $pehdr, 6)){
       ($sig,$skip,$machine)=unpack('a2a2v', $pehdr);
       die("No a PE Executable") if ($sig ne 'PE');

       if ($machine == 0x014c){
            print "i386\n";
       }
       elsif ($machine == 0x0200){
            print "IA64\n";
       }
       elsif ($machine == 0x8664){
            print "AMD64\n";
       }
       else{
            printf("Unknown machine type 0x%lx\n", $machine);
       }
   }
}

close(EXE);

IDLE's console does not support ANSI escape sequences, or any other form of escapes for coloring your output.

You can learn how to talk to IDLE's console directly instead of just treating it like normal stdout and printing to it (which is how it does things like color-coding your syntax), but that's pretty complicated. The idle documentation just tells you the basics of using IDLE itself, and its idlelib library has no documentation (well, there is a single line of documentation—"(New in 2.3) Support library for the IDLE development environment."—if you know where to find it, but that isn't very helpful). So, you need to either read the source, or do a whole lot of trial and error, to even get started.

Alternatively, you can run your script from the command line instead of from IDLE, in which case you can use whatever escape sequences your terminal handles. Most modern terminals will handle at least basic 16/8-color ANSI. Many will handle 16/16, or the expanded xterm-256 color sequences, or even full 24-bit colors. (I believe gnome-terminal is the default for Ubuntu, and in its default configuration it will handle xterm-256, but that's really a question for SuperUser or AskUbuntu.)

Learning to read the termcap entries to know which codes to enter is complicated… but if you only care about a single console—or are willing to just assume "almost everything handles basic 16/8-color ANSI, and anything that doesn't, I don't care about", you can ignore that part and just hardcode them based on, e.g., this page.

Once you know what you want to emit, it's just a matter of putting the codes in the strings before printing them.

But there are libraries that can make this all easier for you. One really nice library, which comes built in with Python, is curses. This lets you take over the terminal and do a full-screen GUI, with colors and spinning cursors and anything else you want. It is a little heavy-weight for simple uses, of course. Other libraries can be found by searching PyPI, as usual.

Ugly, (and doesn't use your method call above) but works:

echo 'First day of the month: ' . date('m/d/y h:i a',(strtotime('this month',strtotime(date('m/01/y')))));   

// example of goto in javascript:

var i, j;
loop_1:
    for (i = 0; i < 3; i++) { //The first for statement is labeled "loop_1"
        loop_2:
            for (j = 0; j < 3; j++) { //The second for statement is labeled "loop_2"
                if (i === 1 && j === 1) {
                    continue loop_1;
                }
                console.log('i = ' + i + ', j = ' + j);
            }
        }

Add the border to each cell with this:

table > tbody > tr > td { border: 1px solid rgba(255, 255, 255, 0.1); }

Remove the top border from all the cells in the first row:

table > tbody > tr:first-child > td { border-top: 0; }

Remove the left border from the cells in the first column:

table > tbody > tr > td:first-child { border-left: 0; }

Remove the right border from the cells in the last column:

table > tbody > tr > td:last-child { border-right: 0; }

Remove the bottom border from the cells in the last row:

table > tbody > tr:last-child > td { border-bottom: 0; }

Why don't you place the account number in a div. Style it as you please and then have a hidden input in the form that also contains the account number. Then when the form gets submitted, the value should come through and not be null.

Why not simply add the following to the beginning of the script

PRINT 'INACTIVE SCRIPT'
RETURN

Small observation. Automation mechanism to dynamically generate SQL using the 'partition by' it is much simpler to implement in relation to the 'group by'. In the case of 'group by', We must take care of the content of 'select' column.

Sorry for My English.

ADD go /usr/local/

will copy the contents of your local go directory in the /usr/local/ directory of your docker image.

To copy the go directory itself in /usr/local/ use:

ADD go /usr/local/go

or

COPY go /usr/local/go

If (ds != null)

Should do the work for you!

I don't know if this still is an issue, but i prefere just to use the My.Settings in my code.

Visual Studio generates a simple class with functions for reading settings from the app.config file.

You can simply access it using My.Settings.ConnectionString.

    Using Context As New Data.Context.DataClasses()
        Context.Connection.ConnectionString = My.Settings.ConnectionString
    End Using

I'm not absolutely sure I got your question correctly, but it seems you want something like this:

    Class c = null;
    try {
        c = Class.forName("com.path.to.ImplementationType");
    } catch (ClassNotFoundException e) {
        e.printStackTrace();
    }
    T interfaceType = null;
    try {
        interfaceType = (T) c.newInstance();
    } catch (InstantiationException e) {
        e.printStackTrace();
    } catch (IllegalAccessException e) {
        e.printStackTrace();
    }

Where T can be defined in method level or in class level, i.e. <T extends InterfaceType>

import re
result=[x for x in re.split(',| ',your_string) if x!='']

this works fine for me.

I wrote a very simple class for exporting to "Excel XML" aka SpreadsheetML. It's not quite as convenient for the end user as XSLX (depending on file extension and Excel version, they may get a warning message), but it's a lot easier to work with than XLS or XLSX.

In Angular / Ionic / VueJS -- I just came up with a simple method of:

stripNaN(txt: any) {
    return txt.toString().replace(/[^a-zA-Z0-9]/g, "");
}

Usage on the view:

<a [href]="'tel:'+stripNaN(single.meta['phone'])" [innerHTML]="stripNaN(single.meta['phone'])"></a>

Use a DateFormat. In an internationalized application, use the format provide by getInstance. If you want to explicitly control the format, create a new SimpleDateFormat yourself.

The simplest way would be to convert your hexadecimal string to a byte array and use the File.WriteAllBytes method.

Using the StringToByteArray() method from this question, you'd do something like this:

string hexString = "0CFE9E69271557822FE715A8B3E564BE";

File.WriteAllBytes("output.dat", StringToByteArray(hexString));

The StringToByteArray method is included below:

public static byte[] StringToByteArray(string hex) {
    return Enumerable.Range(0, hex.Length)
                     .Where(x => x % 2 == 0)
                     .Select(x => Convert.ToByte(hex.Substring(x, 2), 16))
                     .ToArray();
}

For anyone who's looking to do this in 2018, I've got a much better and simpler solution then all the old stuff posted here. You can make a nice looking drag & drop box with just vanilla HTML, JavaScript and CSS.

(Only works in Chrome so far)

Let's start with the HTML.

<div>
<input type="file" name="file" id="file" class="file">
<span id="value"></span>
</div>

Then we'll get to the styling.

    .file {
        width: 400px;
        height: 50px;
        background: #171717;
        padding: 4px;
        border: 1px dashed #333;
        position: relative;
        cursor: pointer;
    }

    .file::before {
        content: '';
        position: absolute;
        background: #171717;
        font-size: 20px;
        top: 50%;
        left: 50%;
        transform: translate(-50%, -50%);
        width: 100%;
        height: 100%;
    }

    .file::after {
        content: 'Drag & Drop';
        position: absolute;
        color: #808080;
        font-size: 20px;
        top: 50%;
        left: 50%;
        transform: translate(-50%, -50%);
    }

After you've done this it already looks fine. But I imagine you'd like to see what file you actaully uploaded, so we're going to do some JavaScript. Remember that pfp-value span? That's where we'll print out the file name.

let file = document.getElementById('file');
file.addEventListener('change', function() {
    if(file && file.value) {
        let val = file.files[0].name;
        document.getElementById('value').innerHTML = "Selected" + val;
    }
});

And that's it.
