Round tripping dates through strings has always been a pain...but the docs to indicate that the 'o' specifier is the one to use for round tripping which captures the UTC state. When parsed the result will usually have Kind == Utc if the original was UTC. I've found that the best thing to do is always normalize dates to either UTC or local prior to serializing then instruct the parser on which normalization you've chosen.

DateTime now = DateTime.Now;
DateTime utcNow = now.ToUniversalTime();

string nowStr = now.ToString( "o" );
string utcNowStr = utcNow.ToString( "o" );

now = DateTime.Parse( nowStr );
utcNow = DateTime.Parse( nowStr, null, DateTimeStyles.AdjustToUniversal );

Debug.Assert( now == utcNow );

Bitcode refers to to the type of code: "LLVM Bitcode" that is sent to iTunes Connect. This allows Apple to use certain calculations to re-optimize apps further (e.g: possibly downsize executable sizes). If Apple needs to alter your executable then they can do this without a new build being uploaded.

This differs from: Slicing which is the process of Apple optimizing your app for a user's device based on the device's resolution and architecture. Slicing does not require Bitcode. (Ex: only including @2x images on a 5s)

App Thinning is the combination of slicing, bitcode, and on-demand resources

Bitcode is an intermediate representation of a compiled program. Apps you upload to iTunes Connect that contain bitcode will be compiled and linked on the App Store. Including bitcode will allow Apple to re-optimize your app binary in the future without the need to submit a new version of your app to the store.

Apple Documentation on App Thinning

After searching a lot I find out that it is possible to create a new folder from the web interface, but it would require you to have at least one file within the folder when creating it.

When using the normal way of creating new files through the web interface, you can type in the folder into the file name to create the file within that new directory.

For example, if I would like to create the file filename.md in a series of sub-folders, I can do this (taken from the GitHub blog):

Use json_encode() if possible (PHP 5.2+).

See this one (maybe duplicate?): Pass a PHP string to a JavaScript variable (and escape newlines)

Edit: Seems the OP is running a long script, in that case one only needs to wrap the part of the script after the quality control with

if (n >= 500) {

.... long running code here

}

If breaking out of a function, you'll probably just want return(), either explicitly or implicitly.

For example, an explicit double return

foo <- function(x) {
  if(x < 10) {
    return(NA)
  } else {
    xx <- seq_len(x)
    xx <- cumsum(xx)
  }
  xx ## return(xx) is implied here
}

> foo(5)
[1] 0
> foo(10)
 [1]  1  3  6 10 15 21 28 36 45 55

By return() being implied, I mean that the last line is as if you'd done return(xx), but it is slightly more efficient to leave off the call to return().

Some consider using multiple returns bad style; in long functions, keeping track of where the function exits can become difficult or error prone. Hence an alternative is to have a single return point, but change the return object using the if () else () clause. Such a modification to foo() would be

foo <- function(x) {
  ## out is NA or cumsum(xx) depending on x
  out <- if(x < 10) {
    NA
  } else {
    xx <- seq_len(x)
    cumsum(xx)
  }
  out ## return(out) is implied here
}

> foo(5)
[1] NA
> foo(10)
 [1]  1  3  6 10 15 21 28 36 45 55

The command that worked in my case was:

xsd /c your.xsd 

Note: u should login as root user

 SET PASSWORD FOR 'root'@'localhost' = PASSWORD('your password');

1. del /s /q c:\where ever the file is\*
2. rmdir /s /q c:\where ever the file is\
3. mkdir c:\where ever the file is\

If you already have the figure object use:

f.set_figheight(15)
f.set_figwidth(15)

But if you use the .subplots() command (as in the examples you're showing) to create a new figure you can also use:

f, axs = plt.subplots(2,2,figsize=(15,15))

I had the same problem using Carthage for dependencies.

Just go to Select Project -> Build Settings -> Search for Enable Bitcode -> If it is selected to Yes, select No.

That solved this problem for me.

You should just use Spread operator:

var myMap = new Map([["thing1", 1], ["thing2", 2], ["thing3", 3]]);_x000D_
_x000D_
var newArr = [...myMap].map(value => value[1] + 1);_x000D_
console.log(newArr); //[2, 3, 4]_x000D_
_x000D_
var newArr2 = [for(value of myMap) value = value[1] + 1];_x000D_
console.log(newArr2); //[2, 3, 4]

The (un)safe way to do this - if you are ok with not using option explicit - is...

Not TypeName(myObj) = "Empty"

This also handles the case if the object has not been declared. This is useful if you want to just comment out a declaration to switch off some behaviour...

Dim myObj as Object
Not TypeName(myObj) = "Empty"  '/ true, the object exists - TypeName is Object

'Dim myObj as Object
Not TypeName(myObj) = "Empty"  '/ false, the object has not been declared

This works because VBA will auto-instantiate an undeclared variable as an Empty Variant type. It eliminates the need for an auxiliary Boolean to manage the behaviour.

If I understand your requirement correctly, the simple answer is: you can't.

That's because the client of the WCF service may be generated by any third party that uses your service.

IF you have control of the clients of your service, you can create a base client class that add the desired header and inherit the behavior on the worker classes.

You need to install the provisioning profile (drag and drop it into iTunes). Then drag and drop the .ipa. Ensure you device is set to sync apps, and try again.

Here's a cool and scalable design pattern that runs in O(n) time ...

a = [1,2,3,4,5,6,7,6,5,4,3,2,1]

replacements = {
    1: 10,
    2: 20,
    3: 30,
}

a = [replacements.get(x, x) for x in a]

print(a)
# Returns [10, 20, 30, 4, 5, 6, 7, 6, 5, 4, 30, 20, 10]

you should change the owner of the server by chown command

from home you can run this command

sudo chown {userName} -R ../../opt

If it does not work yet, run this command

sudo chmod 777 -R ../../opt

It should work now.

Also, Jackson 1.6 has support for handling bi-directional references... which seems like what you are looking for (this blog entry also mentions the feature)

And as of July 2011, there is also "jackson-module-hibernate" which might help in some aspects of dealing with Hibernate objects, although not necessarily this particular one (which does require annotations).

Adding my two cents here since I have not seen an answer that uses the option "Build with parameters" in Jenkins.

Here I am using Jenkins CI browser console for project starwars_api and I was able to build directly with "Build with parameters" with value refs/tags/tag-name

1. choose the "build with parameters" option.
2. add value in the box as "refs/tags/tag_142" (tag_name = tag_142 for my example)

build with ref tag name

You can attach a SLOT to the

void aboutToQuit();

signal of your QApplication. This signal should be raised just before app closes.

Change the default block from "Code" to "Markdown" before running this code:

![<caption>](image_filename.png)

If image file is in another folder, you can do the following:

![<caption>](folder/image_filename.png)

LD_LIBRARY_PATH is Linux specific and is an environment variable pointing to directories where the dynamic loader should look for shared libraries.

Try to add the directory where your .dll is in the PATH variable. Windows will automatically look in the directories listet in this environment variable. LD_LIBRARY_PATH probably won't solve the problem (unless the JVM uses it - I do not know about that).

Signalling in Linux can be done with "kill" (man kill for the available signals), you'd need the process ID to do that. (ps ax | grep java) or something like that, or store the process id when the process gets created (this is used in most linux startup files, see /etc/init.d)

Portable signalling can be done by integrating a SocketServer in your java application. It's not that difficult and gives you the freedom to send any command you want.

If you meant finally clauses in stead of finalizers; they do not get extecuted when System.exit() is called. Finalizers should work, but shouldn't really do anything more significant but print a debug statement. They're dangerous.

The WebClient class should be more than capable of handling the functionality you describe, for example:

System.Net.WebClient wc = new System.Net.WebClient();
byte[] raw = wc.DownloadData("http://www.yoursite.com/resource/file.htm");

string webData = System.Text.Encoding.UTF8.GetString(raw);

or (further to suggestion from Fredrick in comments)

System.Net.WebClient wc = new System.Net.WebClient();
string webData = wc.DownloadString("http://www.yoursite.com/resource/file.htm");

When you say it took 30 seconds, can you expand on that a little more? There are many reasons as to why that could have happened. Slow servers, internet connections, dodgy implementation etc etc.

You could go a level lower and implement something like this:

HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create("http://www.yoursite.com/resource/file.htm");

using (StreamWriter streamWriter = new StreamWriter(webRequest.GetRequestStream(), Encoding.UTF8))
{
    streamWriter.Write(requestData);
}

string responseData = string.Empty;
HttpWebResponse httpResponse = (HttpWebResponse)webRequest.GetResponse();
using (StreamReader responseReader = new StreamReader(httpResponse.GetResponseStream()))
{
    responseData = responseReader.ReadToEnd();
}

However, at the end of the day the WebClient class wraps up this functionality for you. So I would suggest that you use WebClient and investigate the causes of the 30 second delay.

I was having the exact same issue, I triple checked the include paths, I also checked that pear was installed and everything looked OK and I was still getting the errors, after a few hours of going crazy looking at this I realized that in my script had this:

include_once "../Mail.php";

instead of:

include_once ("../Mail.php");

Yup, the stupid parenthesis was missing, but there was no generated error on this line of my script which was odd to me

For the way how question is formulated, the most answers here are answering it correctly.

However, considering how the things should be really done, taking to acount decades and decades of computer science, it comes to my total suprise that there is actually only one answer here (from GrantJ user) suggesting usage of sorted associative containers (sortedcontainers) which sorts elements based on key at their insertions point.

That will avoid massive performance impact per each calling of sort(...) (at minimum O(N*log(N)), where N is in number of elements (logically, this applies for all such solutions here which suggest to use the sort(...)). Take to account that for all such solutions, the sort(...) will need to be called every time when colletion needs to be accessed as sorted AFTER it was modified by adding/removing elements ...

Here is my easy solution for this:

Click on Gradle button, you can find at the right side top. you will see all the gradle files. Now go to android, and double click on signingReport. Once the gradle build finishes, you see the SHA key. Check the below images for step by step guide.

Once you click on Gradle check the below images. Hope this helps someone.

STEP 1:

STEP 2:

Just to add another possibility, you can use untangle, as it is a simple xml-to-python-object library. Here you have an example:

Installation:

pip install untangle

Usage:

Your XML file (a little bit changed):

<foo>
   <bar name="bar_name">
      <type foobar="1"/>
   </bar>
</foo>

Accessing the attributes with untangle:

import untangle

obj = untangle.parse('/path_to_xml_file/file.xml')

print obj.foo.bar['name']
print obj.foo.bar.type['foobar']

The output will be:

bar_name
1

More information about untangle can be found in "untangle".

Also, if you are curious, you can find a list of tools for working with XML and Python in "Python and XML". You will also see that the most common ones were mentioned by previous answers.

super() can be used only in the new-style classes, which means the root class needs to inherit from the 'object' class.

For example, the top class need to be like this:

class SomeClass(object):
    def __init__(self):
        ....

not

class SomeClass():
    def __init__(self):
        ....

So, the solution is that call the parent's init method directly, like this way:

class TextParser(HTMLParser):
    def __init__(self):
        HTMLParser.__init__(self)
        self.all_data = []

There are lots of answers here but unfortunately all of them are quite old and therefore rely on attr/removeAttr which is really not the way to go.

@coffeeyesplease correctly mentions that a good, cross-browser solution is to use

$("select").val([]);

Another good cross-browser solution is

// Note the use of .prop instead of .attr
$("select option").prop("selected", false);

You can see it run a self-test here. Tested on IE 7/8/9, FF 11, Chrome 19.

Here is an interesting blog entry about numbers / limitations of Excel 2007. According to the author the new limit is approximately one million rows.

Sounds like you have a pre-Excel 2007 workbook open in Excel 2007 in compatibility mode (look in the title bar and see if it says compatibility mode). If so, the workbook has 65,536 rows, not 1,048,576. You can save the workbook as an Excel workbook which will be in Excel 2007 format, close the workbook and re-open it.

You should be escaping each of these strings (in both snippets) with mysql_real_escape_string().

http://us3.php.net/mysql-real-escape-string

The reason your two queries are behaving differently is likely because you have magic_quotes_gpc turned on (which you should know is a bad idea). This means that strings gathered from $_GET, $_POST and $_COOKIES are escaped for you (i.e., "O'Brien" -> "O\'Brien").

Once you store the data, and subsequently retrieve it again, the string you get back from the database will not be automatically escaped for you. You'll get back "O'Brien". So, you will need to pass it through mysql_real_escape_string().

Angular 6.1 and later:

You can use built in solution available in Angular 6.1+ with option scrollPositionRestoration: 'enabled' to achieve the same.

@NgModule({
  imports: [RouterModule.forRoot(routes,{
    scrollPositionRestoration: 'enabled'
  })],
  exports: [RouterModule]
})

Angular 6.0 and earlier:

import { Component, OnInit } from '@angular/core';
import { Router, NavigationStart, NavigationEnd } from '@angular/router';
import { Location, PopStateEvent } from "@angular/common";

@Component({
    selector: 'my-app',
    template: '<ng-content></ng-content>',
})
export class MyAppComponent implements OnInit {

    private lastPoppedUrl: string;
    private yScrollStack: number[] = [];

    constructor(private router: Router, private location: Location) { }

    ngOnInit() {
        this.location.subscribe((ev:PopStateEvent) => {
            this.lastPoppedUrl = ev.url;
        });
        this.router.events.subscribe((ev:any) => {
            if (ev instanceof NavigationStart) {
                if (ev.url != this.lastPoppedUrl)
                    this.yScrollStack.push(window.scrollY);
            } else if (ev instanceof NavigationEnd) {
                if (ev.url == this.lastPoppedUrl) {
                    this.lastPoppedUrl = undefined;
                    window.scrollTo(0, this.yScrollStack.pop());
                } else
                    window.scrollTo(0, 0);
            }
        });
    }
}

Note: The expected behavior is that when you navigate back to the page, it should remain scrolled down to the same location it was when you clicked on the link, but scrolling to the top when arriving at every page.

You could use SysInternal's PsExec.

Here is another solution using Jquery I find it a little easier and neater than inline JS sometimes.

    <html>
    <head>
    <script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.1/jquery.min.js"></script>
    <script>

        /* if you prefer to functionize and use onclick= rather then the .on bind
        function hide_show(){
            $(this).hide();
            $("#hidden-div").show();
        }
        */

        $(function(){
            $("#chkbtn").on('click',function() {
                $(this).hide();
                $("#hidden-div").show();
            }); 
        });
    </script>
    <style>
    .hidden-div {
        display:none
    }
    </style>
    </head>
    <body>
    <div class="reform">
        <form id="reform" action="action.php" method="post" enctype="multipart/form-data">
        <input type="hidden" name="type" value="" />
            <fieldset>
                content here...
            </fieldset>

                <div class="hidden-div" id="hidden-div">

            <fieldset>
                more content here that is hidden until the button below is clicked...
            </fieldset>
        </form>
                </div>
                <span style="display:block; padding-left:640px; margin-top:10px;"><button id="chkbtn">Check Availability</button></span>
    </div>
    </body>
    </html>

There's no need to do this in two commits, you can add the file and mark it executable in a single commit:

C:\Temp\TestRepo>touch foo.sh

C:\Temp\TestRepo>git add foo.sh

C:\Temp\TestRepo>git ls-files --stage
100644 e69de29bb2d1d6434b8b29ae775ad8c2e48c5391 0       foo.sh

As you note, after adding, the mode is 0644 (ie, not executable). However, we can mark it as executable before committing:

C:\Temp\TestRepo>git update-index --chmod=+x foo.sh

C:\Temp\TestRepo>git ls-files --stage
100755 e69de29bb2d1d6434b8b29ae775ad8c2e48c5391 0       foo.sh

And now the file is mode 0755 (executable).

C:\Temp\TestRepo>git commit -m"Executable!"
[master (root-commit) 1f7a57a] Executable!
 1 file changed, 0 insertions(+), 0 deletions(-)
 create mode 100755 foo.sh

And now we have a single commit with a single executable file.

In usecase where you want to serialize/deserialize POCOs, Newtonsoft's JSON library is really good. I use it to persist POCOs within SQL Server as JSON strings in an nvarchar field. Caveat is that since its not true de/serialization, it will not preserve private/protected members and class hierarchy.

Standard Subversion layout

Create a git clone of that includes your Subversion trunk, tags, and branches with

git svn clone http://svn.example.com/project -T trunk -b branches -t tags

The --stdlayout option is a nice shortcut if your Subversion repository uses the typical structure:

git svn clone http://svn.example.com/project --stdlayout

Make your git repository ignore everything the subversion repo does:

git svn show-ignore >> .git/info/exclude

You should now be able to see all the Subversion branches on the git side:

git branch -r

Say the name of the branch in Subversion is waldo. On the git side, you'd run

git checkout -b waldo-svn remotes/waldo

The -svn suffix is to avoid warnings of the form

warning: refname 'waldo' is ambiguous.

To update the git branch waldo-svn, run

git checkout waldo-svn
git svn rebase

Starting from a trunk-only checkout

To add a Subversion branch to a trunk-only clone, modify your git repository's .git/config to contain

[svn-remote "svn-mybranch"]
        url = http://svn.example.com/project/branches/mybranch
        fetch = :refs/remotes/mybranch

You'll need to develop the habit of running

git svn fetch --fetch-all

to update all of what git svn thinks are separate remotes. At this point, you can create and track branches as above. For example, to create a git branch that corresponds to mybranch, run

git checkout -b mybranch-svn remotes/mybranch

For the branches from which you intend to git svn dcommit, keep their histories linear!

For me brew postinstall python3 didn't work. I found this solution on the GitHub Homebrew issues page:

$ brew rm python
$ rm -rf /usr/local/opt/python
$ brew cleanup
$ brew install python3

OSX and Android Studio version:

CMD+ [ and CMD+ ]

to move to the previous carret location.

You can use boost::posix_time::time_duration to get the time range. E.g like this

boost::posix_time::time_duration diff = tick - now;
diff.total_milliseconds();

And to get a higher resolution you can change the clock you are using. For example to the boost::posix_time::microsec_clock, though this can be OS dependent. On Windows, for example, boost::posix_time::microsecond_clock has milisecond resolution, not microsecond.

An example which is a little dependent on the hardware.

int main(int argc, char* argv[])
{
    boost::posix_time::ptime t1 = boost::posix_time::second_clock::local_time();
    boost::this_thread::sleep(boost::posix_time::millisec(500));
    boost::posix_time::ptime t2 = boost::posix_time::second_clock::local_time();
    boost::posix_time::time_duration diff = t2 - t1;
    std::cout << diff.total_milliseconds() << std::endl;

    boost::posix_time::ptime mst1 = boost::posix_time::microsec_clock::local_time();
    boost::this_thread::sleep(boost::posix_time::millisec(500));
    boost::posix_time::ptime mst2 = boost::posix_time::microsec_clock::local_time();
    boost::posix_time::time_duration msdiff = mst2 - mst1;
    std::cout << msdiff.total_milliseconds() << std::endl;
    return 0;
}

On my win7 machine. The first out is either 0 or 1000. Second resolution. The second one is nearly always 500, because of the higher resolution of the clock. I hope that help a little.

You do not need to parse every single line and then concatenate them again...

  val source: BufferedSource = Source.fromFile(path)(Codec.UTF8)

terrific answer from DuckPuncher, for Python3 make sure you install pdfminer2 and do:

import io

from pdfminer.pdfinterp import PDFResourceManager, PDFPageInterpreter
from pdfminer.converter import TextConverter
from pdfminer.layout import LAParams
from pdfminer.pdfpage import PDFPage


def convert_pdf_to_txt(path):
    rsrcmgr = PDFResourceManager()
    retstr = io.StringIO()
    codec = 'utf-8'
    laparams = LAParams()
    device = TextConverter(rsrcmgr, retstr, codec=codec, laparams=laparams)
    fp = open(path, 'rb')
    interpreter = PDFPageInterpreter(rsrcmgr, device)
    password = ""
    maxpages = 0
    caching = True
    pagenos = set()

    for page in PDFPage.get_pages(fp, pagenos, maxpages=maxpages,
                                  password=password,
                                  caching=caching,
                                  check_extractable=True):
        interpreter.process_page(page)



    fp.close()
    device.close()
    text = retstr.getvalue()
    retstr.close()
    return text

Scott Jehl came up with a fantastic solution that uses the accelerometer to anticipate orientation changes. This solution is very responsive and does not interfere with zoom gestures.

https://github.com/scottjehl/iOS-Orientationchange-Fix

How it works: This fix works by listening to the device's accelerometer to predict when an orientation change is about to occur. When it deems an orientation change imminent, the script disables user zooming, allowing the orientation change to occur properly, with zooming disabled. The script restores zoom again once the device is either oriented close to upright, or after its orientation has changed. This way, user zooming is never disabled while the page is in use.

Minified source:

/*! A fix for the iOS orientationchange zoom bug. Script by @scottjehl, rebound by @wilto.MIT License.*/(function(m){if(!(/iPhone|iPad|iPod/.test(navigator.platform)&&navigator.userAgent.indexOf("AppleWebKit")>-1)){return}var l=m.document;if(!l.querySelector){return}var n=l.querySelector("meta[name=viewport]"),a=n&&n.getAttribute("content"),k=a+",maximum-scale=1",d=a+",maximum-scale=10",g=true,j,i,h,c;if(!n){return}function f(){n.setAttribute("content",d);g=true}function b(){n.setAttribute("content",k);g=false}function e(o){c=o.accelerationIncludingGravity;j=Math.abs(c.x);i=Math.abs(c.y);h=Math.abs(c.z);if(!m.orientation&&(j>7||((h>6&&i<8||h<8&&i>6)&&j>5))){if(g){b()}}else{if(!g){f()}}}m.addEventListener("orientationchange",f,false);m.addEventListener("devicemotion",e,false)})(this);

I think that it should be:

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

string valueStr = "title, genre, director, actor";
var vals = valueStr.Split(',')[0];

vals will give you the title

This isn't as elegant or efficient as the accepted solution, but it's quick to write up. First, permute the array randomly, then select the first K elements. In python,

import numpy

N = 20
K = 5

idx = np.arange(N)
numpy.random.shuffle(idx)

print idx[:K]

getElementById will return false if the element was not found in the DOM.

var el = document.getElementById("customx");
if (el !== null && el.value === "")
{
  //The element was found and the value is empty.
}

You can just use wildcards in the predicate (after IF, WHERE or ON):

@mainstring LIKE '%' + @substring + '%'

or in this specific case

' ' + @mainstring + ' ' LIKE '% ME[., ]%'

(Put the spaces in the quoted string if you're looking for the whole word, or leave them out if ME can be part of a bigger word).

You can disable all of the constaints on your database by the following line of code:

EXEC sp_MSforeachtable "ALTER TABLE ? NOCHECK CONSTRAINT all"

and after the runing your update/delete command, you can enable it again as the following:

EXEC sp_MSforeachtable "ALTER TABLE ? WITH CHECK CHECK CONSTRAINT all"

In my case, it was because I have Eclipse open...

You can try this :

=COUNTIF(Data!A2:A300,"<>"&"")

You can use jQuery plugin with the inview event like this :

jQuery('.your-class-here').one('inview', function (event, visible) {
    if (visible == true) {
      //Enjoy !
    }
});

Note that in both CMake and Autotools you don't always have to set the installation path at configure time. You can use DESTDIR at install time (see also here) instead as in:

make DESTDIR=<installhere> install

See also this question which explains the subtle difference between DESTDIR and PREFIX.

This is intended for staged installs and to allow for storing programs in a different location from where they are run e.g. /etc/alternatives via symbolic links.

However, if your package is relocatable and doesn't need any hard-coded (prefix) paths set via the configure stage you may be able to skip it. So instead of:

cmake -DCMAKE_INSTALL_PREFIX=/usr . && make all install

you would run:

cmake . && make DESTDIR=/usr all install

Note that, as user7498341 points out, this is not appropriate for cases where you really should be using PREFIX.

Assuming state is having a valid boolean value set in your actual code, then the following condition will succeed

if(state)

when state is boolean value is TRUE

If condition checks for the expression whether it is evaluated to TRUE/FALSE. If the expression is simple true then the condition will succeed.

With Java 7, it's as simple as:

final String EoL = System.getProperty("line.separator");
List<String> lines = Files.readAllLines(Paths.get(fileName),
        Charset.defaultCharset());

StringBuilder sb = new StringBuilder();
for (String line : lines) {
    sb.append(line).append(EoL);
}
final String content = sb.toString();

However, it does havea few minor caveats (like handling files that does not fit into the memory).

I would suggest taking a look on corresponding section in the official Java tutorial (that's also the case if you have a prior Java).

As others pointed out, you might find sime 3rd party libraries useful (like Apache commons I/O or Guava).

As indicated in the question, every sub-command is run in its own shell. This makes writing non-trivial shell scripts a little bit messy -- but it is possible! The solution is to consolidate your script into what make will consider a single sub-command (a single line).

Tips for writing shell scripts within makefiles:

1. Escape the script's use of $ by replacing with $$
2. Convert the script to work as a single line by inserting ; between commands
3. If you want to write the script on multiple lines, escape end-of-line with \
4. Optionally start with set -e to match make's provision to abort on sub-command failure
5. This is totally optional, but you could bracket the script with () or {} to emphasize the cohesiveness of a multiple line sequence -- that this is not a typical makefile command sequence

Here's an example inspired by the OP:

mytarget:
    { \
    set -e ;\
    msg="header:" ;\
    for i in $$(seq 1 3) ; do msg="$$msg pre_$${i}_post" ; done ;\
    msg="$$msg :footer" ;\
    echo msg=$$msg ;\
    }

Java Shift Caesar Cipher by shift spaces.

Restrictions:

1. Only works with a positive number in the shift parameter.
2. Only works with shift less than 26.
3. Does a += which will bog the computer down for bodies of text longer than a few thousand characters.
4. Does a cast number to character, so it will fail with anything but ascii letters.
5. Only tolerates letters a through z. Cannot handle spaces, numbers, symbols or unicode.
6. Code violates the DRY (don't repeat yourself) principle by repeating the calculation more than it has to.

Pseudocode:

1. Loop through each character in the string.
2. Add shift to the character and if it falls off the end of the alphabet then subtract shift from the number of letters in the alphabet (26)
3. If the shift does not make the character fall off the end of the alphabet, then add the shift to the character.
4. Append the character onto a new string. Return the string.

Function:

String cipher(String msg, int shift){
    String s = "";
    int len = msg.length();
    for(int x = 0; x < len; x++){
        char c = (char)(msg.charAt(x) + shift);
        if (c > 'z')
            s += (char)(msg.charAt(x) - (26-shift));
        else
            s += (char)(msg.charAt(x) + shift);
    }
    return s;
}

How to invoke it:

System.out.println(cipher("abc", 3));  //prints def
System.out.println(cipher("xyz", 3));  //prints abc

On Galaxy S3 Android 4.3 the path I use is ./storage/extSdCard/Card/ and it does the job. Hope it helps,

You want to take a look at the getifaddrs(3) manual page. There is an example in C in the manpage itself that you can use. You want to get the address with the type AF_LINK.

I created an extension method for re-use.

   public static bool InArray(this string str, string[] values)
    {
        if (Array.IndexOf(values, str) > -1)
            return true;

        return false;
    }

How to call it:

string[] stringArray = { "text1", "text2", "text3", "text4" };
string value = "text3";
if(value.InArray(stringArray))
{
  //do something
}

See the following sample code on how to Build a basic Keras Neural Net Model, save Model (JSON) & Weights (HDF5) and load them:

# create model
model = Sequential()
model.add(Dense(X.shape[1], input_dim=X.shape[1], activation='relu')) #Input Layer
model.add(Dense(X.shape[1], activation='relu')) #Hidden Layer
model.add(Dense(output_dim, activation='softmax')) #Output Layer

# Compile & Fit model
model.compile(loss='binary_crossentropy', optimizer='adam', metrics=['accuracy'])
model.fit(X,Y,nb_epoch=5,batch_size=100,verbose=1)    

# serialize model to JSON
model_json = model.to_json()
with open("Data/model.json", "w") as json_file:
    json_file.write(simplejson.dumps(simplejson.loads(model_json), indent=4))

# serialize weights to HDF5
model.save_weights("Data/model.h5")
print("Saved model to disk")

# load json and create model
json_file = open('Data/model.json', 'r')
loaded_model_json = json_file.read()
json_file.close()
loaded_model = model_from_json(loaded_model_json)

# load weights into new model
loaded_model.load_weights("Data/model.h5")
print("Loaded model from disk")

# evaluate loaded model on test data 
# Define X_test & Y_test data first
loaded_model.compile(loss='binary_crossentropy', optimizer='adam', metrics=['accuracy'])
score = loaded_model.evaluate(X_test, Y_test, verbose=0)
print ("%s: %.2f%%" % (loaded_model.metrics_names[1], score[1]*100))

TikZ can do this.

A quick demo:

\documentclass{article}

\usepackage{tikz}

\begin{document}

\begin{tikzpicture}
  [scale=.8,auto=left,every node/.style={circle,fill=blue!20}]
  \node (n6) at (1,10) {6};
  \node (n4) at (4,8)  {4};
  \node (n5) at (8,9)  {5};
  \node (n1) at (11,8) {1};
  \node (n2) at (9,6)  {2};
  \node (n3) at (5,5)  {3};

  \foreach \from/\to in {n6/n4,n4/n5,n5/n1,n1/n2,n2/n5,n2/n3,n3/n4}
    \draw (\from) -- (\to);

\end{tikzpicture}

\end{document}

produces:

The answer is already posted but note that this will pass the ArrayList by reference. So if you make any changes to the list in the function it will be affected to the original list also.

<access-modfier> <returnType> AnalyseArray(ArrayList<Integer> list)
{
//analyse the list
//return value
}

call it like this:

x=AnalyseArray(list);

or pass a copy of ArrayList:

x=AnalyseArray(list.clone());

You can also simply avoid using numeric IDs as Primary Key. You could use Country codes as primary id if the table holds countries information, or you could use permalinks, if it hold articles for example.

You could also simply use a random, or an MD5 value. All this options have it's own benefits, specially on IT sec. numeric IDs are easy to enumerate.

You can just append

track by version.id

to your ng-options.

IDisposable is often used to exploit the using statement and take advantage of an easy way to do deterministic cleanup of managed objects.

public class LoggingContext : IDisposable {
    public Finicky(string name) {
        Log.Write("Entering Log Context {0}", name);
        Log.Indent();
    }
    public void Dispose() {
        Log.Outdent();
    }

    public static void Main() {
        Log.Write("Some initial stuff.");
        try {
            using(new LoggingContext()) {
                Log.Write("Some stuff inside the context.");
                throw new Exception();
            }
        } catch {
            Log.Write("Man, that was a heavy exception caught from inside a child logging context!");
        } finally {
            Log.Write("Some final stuff.");
        }
    }
}

    :-) Sunday    |    0  ->  Sun
                  |  
        Monday    |    1  ->  Mon
       Tuesday    |    2  ->  Tue
     Wednesday    |    3  ->  Wed
      Thursday    |    4  ->  Thu
        Friday    |    5  ->  Fri
      Saturday    |    6  ->  Sat
                  |  
    :-) Sunday    |    7  ->  Sun

As you can see above, and as said before, the numbers 0 and 7 are both assigned to Sunday. There are also the English abbreviated days of the week listed, which can also be used in the crontab.

Examples of Number or Abbreviation Use

15 09 * * 5,6,0             command
15 09 * * 5,6,7             command
15 09 * * 5-7               command
15 09 * * Fri,Sat,Sun       command

The four examples do all the same and execute a command every Friday, Saturday, and Sunday at 9.15 o'clock.

In Detail

Having two numbers 0 and 7 for Sunday can be useful for writing weekday ranges starting with 0 or ending with 7. So you can write ranges starting with Sunday or ending with it, like 0-2 or 5-7 for example (ranges must start with the lower number and must end with the higher). The abbreviations cannot be used to define a weekday range.

It's very simple to define a function inside razor.

@functions {

    public static HtmlString OrderedList(IEnumerable<string> items)
    { }
}

So you can call a the function anywhere. Like

@Functions.OrderedList(new[] { "Blue", "Red", "Green" })

However, this same work can be done through helper too. As an example

@helper OrderedList(IEnumerable<string> items){
    <ol>
        @foreach(var item in items){
            <li>@item</li>
        }
    </ol>
}

So what is the difference?? According to this previous post both @helpers and @functions do share one thing in common - they make code reuse a possibility within Web Pages. They also share another thing in common - they look the same at first glance, which is what might cause a bit of confusion about their roles. However, they are not the same. In essence, a helper is a reusable snippet of Razor sytnax exposed as a method, and is intended for rendering HTML to the browser, whereas a function is static utility method that can be called from anywhere within your Web Pages application. The return type for a helper is always HelperResult, whereas the return type for a function is whatever you want it to be.

Sample code you can use to let Tika take care of container files for you. http://wiki.apache.org/tika/RecursiveMetadata

Form what I can tell, the accepted solution will not work for cases where there are nested zip files. Tika, however will take care of such situations as well.

In PHP, you could use following code:

$collection->find(array('name'=> array('$regex' => 'm'));

I think the DocumentCompleted event will get fired for all child documents that are loaded as well (like JS and CSS, for example). You could look at the WebBrowserDocumentCompletedEventArgs in DocumentCompleted and check the Url property and compare that to the Url of the main page.

A "mocking framework", which Mockito is based on, is a framework that gives you the ability to create Mock objects ( in old terms these objects could be called shunts, as they work as shunts for dependend functionality ) In other words, a mock object is used to imitate the real object your code is dependend on, you create a proxy object with the mocking framework. By using mock objects in your tests you are essentially going from normal unit testing to integrational testing

Mockito is an open source testing framework for Java released under the MIT License, it is a "mocking framework", that lets you write beautiful tests with clean and simple API. There are many different mocking frameworks in the Java space, however there are essentially two main types of mock object frameworks, ones that are implemented via proxy and ones that are implemented via class remapping.

Dependency injection frameworks like Spring allow you to inject your proxy objects without modifying any code, the mock object expects a certain method to be called and it will return an expected result.

The @InjectMocks annotation tries to instantiate the testing object instance and injects fields annotated with @Mock or @Spy into private fields of the testing object.

MockitoAnnotations.initMocks(this) call, resets testing object and re-initializes mocks, so remember to have this at your @Before / @BeforeMethod annotation.

FFmpeg has three concatenation methods:

1. concat video filter

Use this method if your inputs do not have the same parameters (width, height, etc), or are not the same formats/codecs, or if you want to perform any filtering.

Note that this method performs a re-encode of all inputs. If you want to avoid the re-encode, you could re-encode just the inputs that don't match so they share the same codec and other parameters, then use the concat demuxer to avoid re-encoding everything.

ffmpeg -i opening.mkv -i episode.mkv -i ending.mkv \
       -filter_complex "[0:v] [0:a] [1:v] [1:a] [2:v] [2:a] 
                        concat=n=3:v=1:a=1 [v] [a]" \
       -map "[v]" -map "[a]" output.mkv

2. concat demuxer

Use this method when you want to avoid a re-encode and your format does not support file-level concatenation (most files used by general users do not support file-level concatenation).

$ cat mylist.txt
file '/path/to/file1'
file '/path/to/file2'
file '/path/to/file3'
    
$ ffmpeg -f concat -safe 0 -i mylist.txt -c copy output.mp4

For Windows:

(echo file 'first file.mp4' & echo file 'second file.mp4' )>list.txt
ffmpeg -safe 0 -f concat -i list.txt -c copy output.mp4

3. concat protocol

Use this method with formats that support file-level concatenation (MPEG-1, MPEG-2 PS, DV). Do not use with MP4.

ffmpeg -i "concat:input1|input2" -codec copy output.mkv

This method does not work for many formats, including MP4, due to the nature of these formats and the simplistic concatenation performed by this method.

If in doubt about which method to use, try the concat demuxer.

var filtered = projects;
foreach (var tag in filteredTags) {
  filtered = filtered.Where(p => p.Tags.Contains(tag))
}

The nice thing with this approach is that you can refine search results incrementally.

Looks like all the useEffect examples dont factor in you might want to trigger this with a state change.

const [aStateVariable, setAStateVariable] = useState(false);

const handleClick = () => {
   setAStateVariable(true);
}

useEffect(() => {
  if(aStateVariable === true) {
    window.scrollTo(0, 0)
  }
}, [aStateVariable])

EDIT: as of Java8 you'd better use Files class:

Path resultingPath = Files.createDirectories('A/B');

I don't know if this ultimately fixes your problem but class File has method mkdirs() which fully creates the path specified by the file.

File f = new File("/A/B/");
f.mkdirs();

just do the following , you can make --test = True by using

python filename --test

parser.add_argument("--test" , default=False ,help="test ?", dest='test', action='store_true')

Your question implies that you're willing to modify other parts of the code, even though you can't modify the SQL Statement itself. Instead of removing them from the ListBox Collection, it might be easier to just exclude them in the first place. This code assumes you're connecting to SQL Server:

void PopulateListBox(ListBox listToPopulate)
{
    SqlConnection conn = new SqlConnection("myConnectionString"); 
    SqlCommand cmd = new SqlCommand("spMyStoredProc", conn);
    cmd.CommandType = CommandType.StoredProcedure;
    SqlDataReader reader = cmd.ExecuteReader();
    while (reader.Read())
    {
        string item = reader.GetString(0); //or whatever column is displayed in the list
        if (!item.Contains("OBJECT_"))
            listToPopulate.Items.Add(item); 
    }
}

But if you're absolutely determined to do it this way you should check out this question on modifying an enumerable collection while iterating through it.

Andy E's answer helped me get the correct way to working for me:

$.each(["input[type=text][value=]", "textarea"], function (index, element) {
if (!$(element).val() || !$(element).text()) {
 $(element).css("background-color", "rgba(255,227,3, 0.2)");
}
});

This !$(element).val() did not catch an empty textarea for me. but that whole bang (!) thing did work when combined with text.

I would use the translate method without translation table. It deletes the letters in second argument in recent Python versions.

def remove_chars(line):
    line7=line[7].translate(None,'abcd')
    return line[:7]+[line7]+line[8:]

line= ['ad','da','sdf','asd',
        '3424','342sfas','asdfaf','sdfa',
        'afase']
print line[7]
line = remove_chars(line)
print line[7]

    double d =  3.1493745;
    string s = $"{d:0.00}"; // or $"{d:#.##}"
    Console.WriteLine(s); // Displays 3.15

You can try this solution.... It works great

function explodeX( $delimiters, $string )
{
    return explode( chr( 1 ), str_replace( $delimiters, chr( 1 ), $string ) );
}
$list = 'Thing 1&Thing 2,Thing 3|Thing 4';

$exploded = explodeX( array('&', ',', '|' ), $list );

echo '<pre>';
print_r($exploded);
echo '</pre>';

You have to make sure first that your server allow remote connection so that the function file_get_contents($url) works fine , most server disable this feature for security reason.

select * from

x.order_id desc limit 1;

First select top 100 rows by ordering in ascending and then select last row by ordering in descending and limit to 1. However this is a very expensive statement as it access the data twice.

Don't forget to generate a second password for your Gmail account. You will use this new password in your code. Read this:

https://support.google.com/accounts/answer/185833

If you don't know the size of the browser you can simply center in CSS with the following code:

HTML code:

<div class="firstDiv">Some Text</div>  

CSS code:

 .firstDiv {
  width: 500px;

  position: fixed;
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%);

  background-color: #F1F1F1;
 }

This also helps in any unforeseen changes in the future.

There isn't one, at least, not unless you are using a "developer" tool of some kind in your browser, e.g. Firebug in Firefox or the Developer tools in Safari. Then you can usually use console.log.

I've created a fiddle using your screenshot as a background image and stripping out the extra mark-up, and it seems to work fine

http://jsfiddle.net/fLdQG/2/ (webkit browser required)

Does this work for you? If not, can you update the fiddle with your exact mark-up and CSS?

git checkout --[ours/theirs] . will do what you want, as long as you're at the root of all conflicts. ours/theirs only affects unmerged files so you shouldn't have to grep/find/etc conflicts specifically.

i use firebase-database in html signup but last error i cannot understand if anybody know tell me . error is "Failed to load resource: the server responded with a status of 404 ()"

FWIW I had this same issue. Turned out my xsi:schemaLocation entries were incorrect, so I went to the official docs and pasted theirs into mine:

http://docs.spring.io/spring/docs/current/spring-framework-reference/html/transaction.html section 16.5.6

I had to add a couple more but that was ok. Next up is to find out why this fixed the problem...

Given:

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

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

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

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

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

Which is closely related to the cov function:

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

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

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

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

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

By symmetry, this should also work

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

And it does.

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

Of course, if you don't need really floating-point arithmetic, just arithmetic on e.g. dollar values where there are always exactly two decimal digits, you might just drop the dot (effectively multiplying by 100) and compare the resulting integers.

if [[ $((10#${num1/.})) < $((10#${num2/.})) ]]; then
    ...

This obviously requires you to be sure that both values have the same number of decimal places.

A list of all addresses is stored in a fact ansible_all_ipv4_addresses, a default address in ansible_default_ipv4.address.

---
- hosts: localhost
  connection: local
  tasks:
    - debug: var=ansible_all_ipv4_addresses
    - debug: var=ansible_default_ipv4.address

Then there are addresses assigned to each network interface... In such cases you can display all the facts and find the one that has the value you want to use.

I usually add to index changes I don't want to stash and then stash with --keep-index option.

git add app/controllers/cart_controller.php
git stash --keep-index
git reset

Last step is optional, but usually you want it. It removes changes from index.

Warning As noted in the comments, this puts everything into the stash, both staged and unstaged. The --keep-index just leaves the index alone after the stash is done. This can cause merge conflicts when you later pop the stash.

The best solution is to create a new branch with --orphan option as shown below

git checkout --orphan <branch name>

By this you will be able to create a new branch and directly checkout to the new branch. It will be a parentless branch.

By default the --orphan option doesn't remove the files in the working directory, so you can delete the working directory files by this:

git rm --cached -r

In details what the --orphan does:

--orphan <new_branch>
Create a new orphan branch, named <new_branch>, started from <start_point> and switch to it. The first commit made on this new branch will have no parents and it will be the root of a new history totally disconnected from all the other branches and commits.

The index and the working tree are adjusted as if you had previously run git checkout <start_point>. This allows you to start a new history that records a set of paths similar to <start_point> by easily running git commit -a to make the root commit.

This can be useful when you want to publish the tree from a commit without exposing its full history. You might want to do this to publish an open source branch of a project whose current tree is "clean", but whose full history contains proprietary or otherwise encumbered bits of code.

If you want to start a disconnected history that records a set of paths that is totally different from the one of <start_point>, then you should clear the index and the working tree right after creating the orphan branch by running git rm -rf . from the top level of the working tree. Afterwards you will be ready to prepare your new files, repopulating the working tree, by copying them from elsewhere, extracting a tarball, etc.

The only practical effect of the throw specifier is that if something different from myExc is thrown by your function, std::unexpected will be called (instead of the normal unhandled exception mechanism).

To document the kind of exceptions that a function can throw, I typically do this:

bool
some_func() /* throw (myExc) */ {
}

As John Weldon said all members must be static in a static class. Try

public static class employee
{
     static NameValueCollection appSetting = ConfigurationManager.AppSettings;    

}

This error could be thrown in the following situation as well.

You want to checkout branch called feature from remote repository but the error is thrown because you already have branch called feature/<feature_name> in your local repository.

Simply checkout the feature branch under a different name:

git checkout -b <new_branch_name> <remote>/feature

If you just want to pass a std::string to a function that needs const char* you can use

std::string str;
const char * c = str.c_str();

If you want to get a writable copy, like char *, you can do that with this:

std::string str;
char * writable = new char[str.size() + 1];
std::copy(str.begin(), str.end(), writable);
writable[str.size()] = '\0'; // don't forget the terminating 0

// don't forget to free the string after finished using it
delete[] writable;

Edit: Notice that the above is not exception safe. If anything between the new call and the delete call throws, you will leak memory, as nothing will call delete for you automatically. There are two immediate ways to solve this.

boost::scoped_array

boost::scoped_array will delete the memory for you upon going out of scope:

std::string str;
boost::scoped_array<char> writable(new char[str.size() + 1]);
std::copy(str.begin(), str.end(), writable.get());
writable[str.size()] = '\0'; // don't forget the terminating 0

// get the char* using writable.get()

// memory is automatically freed if the smart pointer goes 
// out of scope

std::vector

This is the standard way (does not require any external library). You use std::vector, which completely manages the memory for you.

std::string str;
std::vector<char> writable(str.begin(), str.end());
writable.push_back('\0');

// get the char* using &writable[0] or &*writable.begin()

See the batch script listed in How To Check If Computer Is Running A 32 Bit or 64 Bit Operating System. It also includes instructions for checking this from the Registry:

You can use the following registry location to check if computer is running 32 or 64 bit of Windows operating system:

HKLM\HARDWARE\DESCRIPTION\System\CentralProcessor\0

You will see the following registry entries in the right pane:

Identifier     REG_SZ             x86 Family 6 Model 14 Stepping 12
Platform ID    REG_DWORD          0x00000020(32)

The above “x86” and “0x00000020(32)” indicate that the operating system version is 32 bit.

If you don't care about legacy browsers:

if ( bank_holidays.indexOf( '06/04/2012' ) > -1 )

if you do care about legacy browsers, there is a shim available on MDN. Otherwise, jQuery provides an equivalent function:

if ( $.inArray( '06/04/2012', bank_holidays ) > -1 )

Well one way to do it is set the height of your body to the height that you want your page to be. In this example I did 600px.

Then set your wrapper height to a percentage of the body here I did 70% This will adjust your table so that it does not fill up the whole screen but in stead just takes up a percentage of the specified page height.

body {
   padding-top: 70px;
   border:1px solid black;
   height:600px;
}

.mygrid-wrapper-div {
   border: solid red 5px;
   overflow: scroll;
   height: 70%;
}

http://jsfiddle.net/4NB2N/7/

Update How about a jQuery approach.

$(function() {  
   var window_height = $(window).height(),
   content_height = window_height - 200;
   $('.mygrid-wrapper-div').height(content_height);
});

$( window ).resize(function() {
   var window_height = $(window).height(),
   content_height = window_height - 200;
   $('.mygrid-wrapper-div').height(content_height);
});

It happens because your maven plugin try to connect to an HTTPS remote repository (https://repo.maven.apache.org/maven2) or (https://repo1.maven.apache.org).

Some time ago, you could to change these URL's to use HTTP instead use HTTPS, but since January 15th 2020, these URL's doesn't work any more, only the HTTPS URL's.

As an easy way to fix this problem, you can use the insecure Maven URL in the settings.xml file. So, you need to change ALL of yours references above mencioned to: http://insecure.repo1.maven.org/maven2/

TIP: Your JAVA_HOME variable always needs to point to your JDK path, not to your JRE path, for example: "C:\Program Files\Java\jdk1.7.0_80".

If the API says to use HTTP Basic authentication, then you need to add an Authorization header to your request. I'd alter your code to look like this:

    WebRequest req = WebRequest.Create(@"https://sub.domain.com/api/operations?param=value&param2=value");
    req.Method = "GET";
    req.Headers["Authorization"] = "Basic " + Convert.ToBase64String(Encoding.Default.GetBytes("username:password"));
    //req.Credentials = new NetworkCredential("username", "password");
    HttpWebResponse resp = req.GetResponse() as HttpWebResponse;

Replacing "username" and "password" with the correct values, of course.

No, you cannot.

From SQL Server Books Online:

User-defined functions cannot be used to perform actions that modify the database state.

Ref.

It's been a while since the OP, but here's my solution for this using Bootstrap 3. In my use case, I was only targeting rows, but the same could be applied to the container, etc.

Just change .row to whatever you want.

jQuery(document).ready(function ($) {

    var alterClass = function () {

        var ww = document.body.clientWidth;

        if (ww < 768) {

            $('.row').addClass('is-xs').removeClass('is-sm').removeClass('is-lg').removeClass('is-md');

        } else if (ww >= 768 && ww < 992) {

            $('.row').addClass('is-sm').removeClass('is-xs').removeClass('is-lg').removeClass('is-md');

        } else if (ww >= 992 && ww < 1200) {

            $('.row').addClass('is-md').removeClass('is-xs').removeClass('is-lg').removeClass('is-sm');

        } else if (ww >= 1200) {

            $('.row').addClass('is-lg').removeClass('is-md').removeClass('is-sm').removeClass('is-xs');

        };
    };

    // Make Changes when the window is resized
    $(window).resize(function () {
        alterClass();
    });

    // Fire when the page first loads
    alterClass();
});

A two value assignment can be used for this purpose. Please check my sample program below

package main

import (
    "fmt"
)

func main() {
    //creating a map with 3 key-value pairs
    sampleMap := map[string]int{"key1": 100, "key2": 500, "key3": 999}
    //A two value assignment can be used to check existence of a key.
    value, isKeyPresent := sampleMap["key2"]
    //isKeyPresent will be true if key present in sampleMap
    if isKeyPresent {
        //key exist
        fmt.Println("key present, value =  ", value)
    } else {
        //key does not exist
        fmt.Println("key does not exist")
    }
}

request.getSession() is just a convenience method. It does exactly the same as request.getSession(true).

From C++17 onward, the <filesystem> header, and range-for, you can simply do this:

#include <filesystem>

using recursive_directory_iterator = std::filesystem::recursive_directory_iterator;
...
for (const auto& dirEntry : recursive_directory_iterator(myPath))
     std::cout << dirEntry << std::endl;

As of C++17, std::filesystem is part of the standard library and can be found in the <filesystem> header (no longer "experimental").

when you say 'appendchild' you actually move your child from one parent to another. you have to create a node for each cell.

sp_helplogins will give you the logins along with the DBs and the rights on them.

Make sure that you embedd the jQuery library into your page by adding the below shown line into your <head> block:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>

If working with Python =2.6 (including 3.x), you can:

from __future__ import division
import operator, itertools

def getmin(alist):
    return min(
        (operator.div(*pair), pair)
        for pair in itertools.product(alist, repeat=2)
    )[1]

getmin([1, 2, 3, 4, 5])

EDIT: Now that I think of it and if I remember my mathematics correctly, this should also give the answer assuming that all numbers are non-negative:

def getmin(alist):
    return min(alist), max(alist)

You can use:

QString::fromStdString(byteArray.toStdString())

@Jon's :parse/:endparse scheme is a great start, and he has my gratitude for the initial pass, but if you think that the Windows torturous batch system would let you off that easy… well, my friend, you are in for a shock. I have spent the whole day with this devilry, and after much painful research and experimentation I finally managed something viable for a real-life utility.

Let us say that we want to implement a utility foobar. It requires an initial command. It has an optional parameter --foo which takes an optional value (which cannot be another parameter, of course); if the value is missing it defaults to default. It also has an optional parameter --bar which takes a required value. Lastly it can take a flag --baz with no value allowed. Oh, and these parameters can come in any order.

In other words, it looks like this:

foobar <command> [--foo [<fooval>]] [--bar <barval>] [--baz]

Complicated? No, that seems pretty typical of real life utilities. (git anyone?)

Without further ado, here is a solution:

@ECHO OFF
SETLOCAL
REM FooBar parameter demo

SET CMD=%~1

IF "%CMD%" == "" (
  GOTO usage
)
SET FOO=
SET DEFAULT_FOO=default

Yes, it really is that bad. See my similar post at https://stackoverflow.com/a/50653047/421049, where I provide more analysis of what is going on in the logic, and why I used certain constructs.

Hideous. Most of that I had to learn today. And it hurt.

Not quite, the AND has to be lower-case.

alter table [table name] remove [present column name] to [new column name.

datetime.datetime.fromtimestamp() is correct, except you are probably having timestamp in miliseconds (like in JavaScript), but fromtimestamp() expects Unix timestamp, in seconds.

Do it like that:

>>> import datetime
>>> your_timestamp = 1331856000000
>>> date = datetime.datetime.fromtimestamp(your_timestamp / 1e3)

and the result is:

>>> date
datetime.datetime(2012, 3, 16, 1, 0)

Does it answer your question?

EDIT: J.F. Sebastian correctly suggested to use true division by 1e3 (float 1000). The difference is significant, if you would like to get precise results, thus I changed my answer. The difference results from the default behaviour of Python 2.x, which always returns int when dividing (using / operator) int by int (this is called floor division). By replacing the divisor 1000 (being an int) with the 1e3 divisor (being representation of 1000 as float) or with float(1000) (or 1000. etc.), the division becomes true division. Python 2.x returns float when dividing int by float, float by int, float by float etc. And when there is some fractional part in the timestamp passed to fromtimestamp() method, this method's result also contains information about that fractional part (as the number of microseconds).

Example solution for adding the library to your PYTHONPATH.

1. Add the following line into your ~/.bashrc or just run it directly:

   export PYTHONPATH="$PYTHONPATH:$HOME/.python"
   

2. Then link your required library into your ~/.python folder, e.g.

   ln -s /home/user/work/project/foo ~/.python/
   

use jQuery's $.getJSON

$.getJSON('mydata.json', function(data) {
    //do stuff with your data here
});

This function should do the trick if you want to specify a particular sheet. I took the solution from user6432984 and modified it to not throw any errors. I am using Excel 2016 so it may not work for older versions:

Function findLastRow(ByVal inputSheet As Worksheet) As Integer
    findLastRow = inputSheet.cellS(inputSheet.Rows.Count, 1).End(xlUp).Row
End Function

This is the code to run if you are already working in the sheet you want to find the last row of:

Dim lastRow as Integer
lastRow = cellS(Rows.Count, 1).End(xlUp).Row

Use the microtime function. The documentation includes example code.

Installing node_modules in container to different from project folder, and setting NODE_PATH to your node_modules folder helps me (u need to rebuild container).

I'm using docker-compose. My project file structure:

-/myproject
--docker-compose.yml
--nodejs/
----Dockerfile

docker-compose.yml:

version: '2'
services:
  nodejs:
    image: myproject/nodejs
    build: ./nodejs/.
    volumes:
      - ./nodejs:/workdir
    ports:
      - "23005:3000"
    command: npm run server

Dockerfile in nodejs folder:

FROM node:argon
RUN mkdir /workdir
COPY ./package.json /workdir/.
RUN mkdir /data
RUN ln -s /workdir/package.json /data/.
WORKDIR /data
RUN npm install
ENV NODE_PATH /data/node_modules/
WORKDIR /workdir

I explored the google docs and found that developer key and api is same thing.

It looks like your are trying to produce/recieve json output. I see two problems with your approach. 1) You didn't specify the application/json in your Accept header 2) You need to specify produces="application/json" in your @RequestMapping

Run your code under a JRockit JVM, then use JRCMD <PID> print_class_summary

This will output all loaded classes, one on each line.

As you say, you don't need to request the file twice. Pass it from your controller to your directive. Assuming you use the directive inside the scope of the controller:

.controller('MyController', ['$scope', '$http', function($scope, $http) {
  $http.get('locations/locations.json').success(function(data) {
      $scope.locations = data;
  });
}

Then in your HTML (where you call upon the directive).
Note: locations is a reference to your controllers $scope.locations.

<div my-directive location-data="locations"></div>

And finally in your directive

...
scope: {
  locationData: '=locationData'
},
controller: ['$scope', function($scope){
  // And here you can access your data
  $scope.locationData
}]
...

This is just an outline to point you in the right direction, so it's incomplete and not tested.

simply add box-sizing: border-box;

-Ldir
Add directory dir to the list of directories to be searched for -l.

I would consider right method from StringUtils class from Apache Commons Lang: http://commons.apache.org/proper/commons-lang/apidocs/org/apache/commons/lang3/StringUtils.html#right(java.lang.String,%20int)

It is safe. You will not get NullPointerException or StringIndexOutOfBoundsException.

Example usage:

StringUtils.right("abcdef", 3)

You can find more examples under the above link.

Use replace()

 s = s.replace("'", "\\'"); 

output:

You\'ll be totally awesome, I\'m really terrible

The best way? Hard to say, the HashSet approach looks fast, but (depending on the data) using a sort algorithm (CountSort ?) can be much faster.

using System;
using System.Collections.Generic;
using System.Linq;
class Program
{
    static void Main()
    {
        Random r = new Random(0); int[] a, b = new int[1000000];
        for (int i = b.Length - 1; i >= 0; i--) b[i] = r.Next(b.Length);
        a = new int[b.Length]; Array.Copy(b, a, b.Length);
        a = dedup0(a); Console.WriteLine(a.Length);
        a = new int[b.Length]; Array.Copy(b, a, b.Length);
        var w = System.Diagnostics.Stopwatch.StartNew();
        a = dedup0(a); Console.WriteLine(w.Elapsed); Console.Read();
    }

    static int[] dedup0(int[] a)  // 48 ms  
    {
        return new HashSet<int>(a).ToArray();
    }

    static int[] dedup1(int[] a)  // 68 ms
    {
        Array.Sort(a); int i = 0, j = 1, k = a.Length; if (k < 2) return a;
        while (j < k) if (a[i] == a[j]) j++; else a[++i] = a[j++];
        Array.Resize(ref a, i + 1); return a;
    }

    static int[] dedup2(int[] a)  //  8 ms
    {
        var b = new byte[a.Length]; int c = 0;
        for (int i = 0; i < a.Length; i++) 
            if (b[a[i]] == 0) { b[a[i]] = 1; c++; }
        a = new int[c];
        for (int j = 0, i = 0; i < b.Length; i++) if (b[i] > 0) a[j++] = i;
        return a;
    }
}

Almost branch free. How? Debug mode, Step Into (F11) with a small array: {1,3,1,1,0}

    static int[] dedupf(int[] a)  //  4 ms
    {
        if (a.Length < 2) return a;
        var b = new byte[a.Length]; int c = 0, bi, ai, i, j;
        for (i = 0; i < a.Length; i++)
        { ai = a[i]; bi = 1 ^ b[ai]; b[ai] |= (byte)bi; c += bi; }
        a = new int[c]; i = 0; while (b[i] == 0) i++; a[0] = i++;
        for (j = 0; i < b.Length; i++) a[j += bi = b[i]] += bi * i; return a;
    }

A solution with two nested loops might take some time, especially for larger arrays.

    static int[] dedup(int[] a)
    {
        int i, j, k = a.Length - 1;
        for (i = 0; i < k; i++)
            for (j = i + 1; j <= k; j++) if (a[i] == a[j]) a[j--] = a[k--];
        Array.Resize(ref a, k + 1); return a;
    }

I don't really see a way to do this as-is. I think you might need to remove the overflow:hidden from div#1 and add another div within div#1 (ie as a sibling to div#2) to hold your unspecified 'content' and add the overflow:hidden to that instead. I don't think that overflow can be (or should be able to be) over-ridden.

The LocalLinks extension from the most popular answer didn't work for me (given, I was trying to use file:// to open a directory in windows explorer, not a file), so I looked into another workaround. I found that this "Open in IE" extension is a good workaround: https://chrome.google.com/webstore/detail/open-in-ie/iajffemldkkhodaedkcpnbpfabiglmdi

This isn't an ideal fix, as instead of clicking the link, users will have to right-click and choose Open in IE, but it at least makes the link functional.

One thing to note though, in IE10 (and IE9 after a certain update point) you will have to add the site to your Trusted Sites (Internet Options > Security > Trusted sites). If the site is not in trusted sites, the file:// link does not work in IE either.

#include<iostream>

            int result;
            number=5;
            cout << "The value of the variable number before calling the function : " << number << endl;
            result=add(&number);
            cout << "The value of the variable number after the function is returned : " << number << endl;
            cout << "The value of result : " << result << endl;
            return(0);
}

int add(int &p)
{
            *p=*p+100;
            return(*p);
}

This is invalid code on several counts. Running it through g++ gives:

crap.cpp: In function ‘int main()’:
crap.cpp:11: error: invalid initialization of non-const reference of type ‘int&’ from a temporary of type ‘int*’
crap.cpp:3: error: in passing argument 1 of ‘int add(int&)’
crap.cpp: In function ‘int add(int&)’:
crap.cpp:19: error: invalid type argument of ‘unary *’
crap.cpp:19: error: invalid type argument of ‘unary *’
crap.cpp:20: error: invalid type argument of ‘unary *’

A valid version of the code reads:

#include<iostream>
using namespace std;
int add(int &number);

int main ()
{
            int number;
            int result;
            number=5;
            cout << "The value of the variable number before calling the function : " << number << endl;
            result=add(number);
            cout << "The value of the variable number after the function is returned : " << number << endl;
            cout << "The value of result : " << result << endl;
            return(0);
}

int add(int &p)
{
            p=p+100;
            return p;
}

What is happening here is that you are passing a variable "as is" to your function. This is roughly equivalent to:

int add(int *p)
{
      *p=*p+100;
      return *p;
}

However, passing a reference to a function ensures that you cannot do things like pointer arithmetic with the reference. For example:

int add(int &p)
{
            *p=*p+100;
            return p;
}

is invalid.

If you must use a pointer to a reference, that has to be done explicitly:

int add(int &p)
{
                    int* i = &p;
            i=i+100L;
            return *i;
}

Which on a test run gives (as expected) junk output:

The value of the variable number before calling the function : 5
The value of the variable number after the function is returned : 5
The value of result : 1399090792

It's probably easiest to create your query object directly as:

  Test.find({
      $and: [
          { $or: [{a: 1}, {b: 1}] },
          { $or: [{c: 1}, {d: 1}] }
      ]
  }, function (err, results) {
      ...
  }

But you can also use the Query#and helper that's available in recent 3.x Mongoose releases:

  Test.find()
      .and([
          { $or: [{a: 1}, {b: 1}] },
          { $or: [{c: 1}, {d: 1}] }
      ])
      .exec(function (err, results) {
          ...
      });

I'm surprised nobody mentioned partition.

def substring_after(s, delim):
    return s.partition(delim)[2]

IMHO, this solution is more readable than @arshajii's. Other than that, I think @arshajii's is the best for being the fastest -- it does not create any unnecessary copies/substrings.

In the first class, sayHi() is actually an instance method which you are calling as a static method and you get away with it because sayHi() never refers to $this.

Static functions are associated with the class, not an instance of the class. As such, $this is not available from a static context ($this isn't pointing to any object).

EXISTS (or NOT EXISTS) is specially designed for checking if something exists and therefore should be (and is) the best option. It will halt on the first row that matches so it does not require a TOP clause and it does not actually select any data so there is no overhead in size of columns. You can safely use SELECT * here - no different than SELECT 1, SELECT NULL or SELECT AnyColumn... (you can even use an invalid expression like SELECT 1/0 and it will not break).

IF EXISTS (SELECT * FROM Products WHERE id = ?)
BEGIN
--do what you need if exists
END
ELSE
BEGIN
--do what needs to be done if not
END

There really isn't a need to create a custom click event as suggested in the bountied answer or to show the url as suggested in the accepted answer.

window.open(url)¹ does open web pages automatically without user interaction, provided pop- up blockers are disabled(as is the case with Stephen's answer)

openUrl.html

<!DOCTYPE html>
<html>
  <head>
   <base target="_blank">
    <script>
     var url1 ='https://stackoverflow.com/a/54675103';
     var winRef = window.open(url1);
     winRef ? google.script.host.close() : window.alert('Allow popup to redirect you to '+url1) ;
     window.onload=function(){document.getElementById('url').href = url1;}
    </script>
  </head>
  <body>
    Kindly allow pop ups</br>
    Or <a id='url'>Click here </a>to continue!!!
  </body>
</html>

code.gs:

function modalUrl(){
  SpreadsheetApp.getUi()
   .showModalDialog(
     HtmlService.createHtmlOutputFromFile('openUrl').setHeight(50),
     'Opening StackOverflow'
   )
}    

A simple solution would be:

package nl;
public class Padder {
    public static void main(String[] args) {
        String s = "123" ;
        System.out.println("#"+("     " + s).substring(s.length())+"#");
    }
}

The change event not firing on deselection is the desired behaviour. You should run a selector over the entire radio group rather than just the single radio button. And your radio group should have the same name (with different values)

Consider the following code:

$('input[name="job[video_need]"]').on('change', function () {
    var value;
    if ($(this).val() == 'none') {
        value = 'hide';
    } else {
        value = 'show';
    }
    $('#video-script-collapse').collapse(value);
});

I have same use case as yours i.e. to show an input box when a particular radio button is selected. If the event was fired on de-selection as well, I would get 2 events each time.

You can use Number() function also since it converts the object argument to a number that represents the object's value.

Eg: javascript:alert( Number("2") > Number("10"))

Create a bash file say move.sh which has the following code C:\cygwin64\bin\run.exe -p /bin bash runFile.sh This starts the Cygwin and executes the runFile.sh present in the bin directory of Cygwin Suppose you want to navigate to a specific directory say E:\code then runFile.sh has the following code cd E: cd code

Don't forget to hit Do Refactor afterwards.

Then you'll need to run another analysis, as the refactored code will no doubt reveal more unused declarations.

Your svn merge syntax is wrong.

You want to checkout a working copy of trunk and then use the svn merge --reintegrate option:

$ pwd
/home/user/project-trunk

$ svn update  # (make sure the working copy is up to date)
At revision <N>.

$ svn merge --reintegrate ^/project/branches/branch_1
--- Merging differences between repository URLs into '.':
U    foo.c
U    bar.c
 U   .

$ # build, test, verify, ...

$ svn commit -m "Merge branch_1 back into trunk!"
Sending        .
Sending        foo.c
Sending        bar.c
Transmitting file data ..
Committed revision <N+1>.

See the SVN book chapter on merging for more details.

Note that at the time it was written, this was the right answer (and was accepted), but things have moved on. See the answer of topek, and http://subversion.apache.org/docs/release-notes/1.8.html#auto-reintegrate

tl;dr

Instant.ofEpochSecond( 1_280_512_800L )

2010-07-30T18:00:00Z

java.time

The new java.time framework built into Java 8 and later is the successor to Joda-Time.

These new classes include a handy factory method to convert a count of whole seconds from epoch. You get an Instant, a moment on the timeline in UTC with up to nanoseconds resolution.

Instant instant = Instant.ofEpochSecond( 1_280_512_800L );

instant.toString(): 2010-07-30T18:00:00Z

See that code run live at IdeOne.com.

Asia/Kabul or Asia/Tehran time zones ?

You reported getting a time-of-day value of 22:30 instead of the 18:00 seen here. I suspect your PHP utility is implicitly applying a default time zone to adjust from UTC. My value here is UTC, signified by the Z (short for Zulu, means UTC). Any chance your machine OS or PHP is set to Asia/Kabul or Asia/Tehran time zones? I suppose so as you report IRST in your output which apparently means Iran time. Currently in 2017 those are the only zones operating with a summer time that is four and a half hours ahead of UTC.

Specify a proper time zone name in the format of continent/region, such as America/Montreal, Africa/Casablanca, or Pacific/Auckland. Never use the 3-4 letter abbreviation such as EST or IST or IRST as they are not true time zones, not standardized, and not even unique(!).

If you want to see your moment through the lens of a particular region's time zone, apply a ZoneId to get a ZonedDateTime. Still the same simultaneous moment, but seen as a different wall-clock time.

ZoneId z = ZoneId.of( "Asia/Tehran" ) ;
ZonedDateTime zdt = instant.atZone( z );  // Same moment, same point on timeline, but seen as different wall-clock time.

2010-07-30T22:30+04:30[Asia/Tehran]

Converting from java.time to legacy classes

You should stick with the new java.time classes. But you can convert to old if required.

java.util.Date date = java.util.Date.from( instant );

Joda-Time

UPDATE: The Joda-Time project is now in maintenance mode, with the team advising migration to the java.time classes.

FYI, the constructor for a Joda-Time DateTime is similar: Multiply by a thousand to produce a long (not an int!).

DateTime dateTime = new DateTime( ( 1_280_512_800L * 1000_L ), DateTimeZone.forID( "Europe/Paris" ) );

Best to avoid the notoriously troublesome java.util.Date and .Calendar classes. But if you must use a Date, you can convert from Joda-Time.

java.util.Date date = dateTime.toDate();

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android (<26), the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

You can get your properties through Environment class. As documentation stands:

Properties play an important role in almost all applications, and may originate from a variety of sources: properties files, JVM system properties, system environment variables, JNDI, servlet context parameters, ad-hoc Properties objects, Maps, and so on. The role of the environment object with relation to properties is to provide the user with a convenient service interface for configuring property sources and resolving properties from them.

Having Environment as a env variable, simply call:

env.resolvePlaceholders("${your-property:default-value}")

You can get your 'raw' properties through:

env.getProperty("your-property")

It will search through all properties source that spring has registered.

You can either obtain Environment through:

• inject ApplicationContext by implementing ApplicationContextAware and then call getEnvironment() on context
• implement EnvironmentAware.

It's obtain through implementation of a class because properties are resolved on early stage of application startup, as they may be required for bean construction.

As was posted earlier, you need to make sure you install the platform plugins when you deploy your application. Depending on how you want to deploy things, there are two methods to tell your application where the platform plugins (e.g. platforms/plugins/libqxcb.so) are at runtime which may work for you.

The first is to export the path to the directory through the QT_QPA_PLATFORM_PLUGIN_PATH variable.

QT_QPA_PLATFORM_PLUGIN_PATH=path/to/plugins ./my_qt_app

or

export QT_QPA_PLATFORM_PLUGIN_PATH=path/to/plugins
./my_qt_app

The other option, which I prefer is to create a qt.conf file in the same directory as your executable. The contents of which would be:

[Paths]
Plugins=/path/to/plugins

More information regarding this can be found here and at using qt.conf

using System.Net;
using System.Net.Mail;

using(SmtpClient smtpClient = new SmtpClient())
{
    var basicCredential = new NetworkCredential("username", "password"); 
    using(MailMessage message = new MailMessage())
    {
        MailAddress fromAddress = new MailAddress("[email protected]"); 

        smtpClient.Host = "mail.mydomain.com";
        smtpClient.UseDefaultCredentials = false;
        smtpClient.Credentials = basicCredential;

        message.From = fromAddress;
        message.Subject = "your subject";
        // Set IsBodyHtml to true means you can send HTML email.
        message.IsBodyHtml = true;
        message.Body = "<h1>your message body</h1>";
        message.To.Add("[email protected]"); 

        try
        {
            smtpClient.Send(message);
        }
        catch(Exception ex)
        {
            //Error, could not send the message
            Response.Write(ex.Message);
        }
    }
}

You may use the above code.

If you are running out of heap space during the surefire (or failsafe) JUnit testing run, changing MAVEN_OPTS may not help you. I kept trying different configurations in MAVEN_OPTS with no luck until I found this post that fixed the problem.

Basically the JUnits fork off into their own environment and ignore the settings in MAVEN_OPTS. You need to configure surefire in your pom to add more memory for the JUnits.

Hopefully this can save someone else some time!

Edit: Copying solution from Keith Chapman's blog just in case the link breaks some day:

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-surefire-plugin</artifactId>
  <configuration>
    <forkMode>pertest</forkMode> 
    <argLine>-Xms256m -Xmx512m</argLine>

    <skip>false</skip> 
    <includes> 
      <include>**/*IntegrationTestSuite.java</include>
    </includes>
  </configuration>
</plugin>

Update (5/31/2017): Thanks to @johnstosh for pointing this out - surefire has evolved a bit since I put this answer out there. Here is a link to their documentation and an updated code sample (arg line is still the important part for this question):

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.20</version>
    <configuration>
        <forkCount>3</forkCount>
        <reuseForks>true</reuseForks>

    </configuration>
  </plugin>

For Bash:

# This will trap any errors or commands with non-zero exit status
# by calling function catch_errors()
trap catch_errors ERR;

#
# ... the rest of the script goes here
#

function catch_errors() {
   # Do whatever on errors
   #
   #
   echo "script aborted, because of errors";
   exit 0;
}

Can be achieved also with scriptrunner

ScriptRunner.exe -appvscript demoA.cmd arg1 arg2 -appvscriptrunnerparameters -wait -timeout=30 -rollbackonerror -appvscript demoB.ps1 arg3 arg4 -appvscriptrunnerparameters -wait -timeout=30 

Which also have some features as rollback , timeout and waiting.

If the width of the contents changes, you'll have to use this bit of code to update each column:

private void ResizeGridViewColumn(GridViewColumn column)
{
    if (double.IsNaN(column.Width))
    {
        column.Width = column.ActualWidth;
    }

    column.Width = double.NaN;
}

You'd have to fire it each time the data for that column updates.

The ? in the parameters is to denote an optional parameter. The Typescript compiler does not require this parameter to be filled in. See the code example below for more details:

// baz: number | undefined means: the second argument baz can be a number or undefined

// = undefined, is default parameter syntax, 
// if the parameter is not filled in it will default to undefined

// Although default JS behaviour is to set every non filled in argument to undefined 
// we need this default argument so that the typescript compiler
// doesn't require the second argument to be filled in
function fn1 (bar: string, baz: number | undefined = undefined) {
    // do stuff
}

// All the above code can be simplified using the ? operator after the parameter
// In other words fn1 and fn2 are equivalent in behaviour
function fn2 (bar: string, baz?: number) {
    // do stuff
}



fn2('foo', 3); // works
fn2('foo'); // works

fn2();
// Compile time error: Expected 1-2 arguments, but got 0
// An argument for 'bar' was not provided.


fn1('foo', 3); // works
fn1('foo'); // works

fn1();
// Compile time error: Expected 1-2 arguments, but got 0
// An argument for 'bar' was not provided.

For php 5.6 on ubuntu 16.04

Heapsort implementation. An O(n log(n)) (both average and worst case), in place, unstable sorting algorithm.

Use with: Call HeapSort(A), where A is a one dimensional array of variants, with Option Base 1.

Sub SiftUp(A() As Variant, I As Long)
    Dim K As Long, P As Long, S As Variant
    K = I
    While K > 1
        P = K \ 2
        If A(K) > A(P) Then
            S = A(P): A(P) = A(K): A(K) = S
            K = P
        Else
            Exit Sub
        End If
    Wend
End Sub

    Do
        L = K + K
        If L > I Then Exit Sub
        If L + 1 <= I Then
            If A(L + 1) > A(L) Then L = L + 1
        End If
        If A(K) < A(L) Then
            S = A(K): A(K) = A(L): A(L) = S
            K = L
        Else
            Exit Sub
        End If
    Loop
End Sub

Sub HeapSort(A() As Variant)
    Dim N As Long, I As Long, S As Variant
    N = UBound(A)
    For I = 2 To N
        Call SiftUp(A, I)
    Next I
    For I = N To 2 Step -1
        S = A(I): A(I) = A(1): A(1) = S
        Call SiftDown(A, I - 1)
    Next
End Sub

Java has a feature called "checked exceptions". That means that there are certain kinds of exceptions, namely those that subclass Exception but not RuntimeException, such that if a method may throw them, it must list them in its throws declaration, say: void readData() throws IOException. IOException is one of those.

Thus, when you are calling a method that lists IOException in its throws declaration, you must either list it in your own throws declaration or catch it.

The rationale for the presence of checked exceptions is that for some kinds of exceptions, you must not ignore the fact that they may happen, because their happening is quite a regular situation, not a program error. So, the compiler helps you not to forget about the possibility of such an exception being raised and requires you to handle it in some way.

However, not all checked exception classes in Java standard library fit under this rationale, but that's a totally different topic.

There is no error when I use your code,

but I am calling the hasLetter method like this:

hasLetter("a",words);

var fs = require('fs');

function base64Encode(file) {
    var body = fs.readFileSync(file);
    return body.toString('base64');
}


var base64String = base64Encode('test.jpg');
console.log(base64String);

In Linux Mint, and most likely Ubuntu, you can try "nvidia-smi --loop=1"

InputStream is = new FileInputStream("c://filename");
return is;

There is another way to do this.

From iTerm2 2.9.20140923 you can use Dynamic Profiles as stated in the documentation page:

Dynamic Profiles is a feature that allows you to store your profiles in a file outside the usual macOS preferences database. Profiles may be changed at runtime by editing one or more plist files (formatted as JSON, XML, or in binary). Changes are picked up immediately.

So it is possible to create a file like this one:

    {
        "Profiles": [{
                "Name": "MYSERVER1",
                "Guid": "MYSERVER1",

in the folder ~/Library/Application\ Support/iTerm2/DynamicProfiles/ and share it across different machines. This enables you to retain some visual differences among iterm2 installations such as font type or dimension, while synchronising remote hosts, shortcuts, commands, and even a small badge to quickly identify a session

I know this question is old but, I noticed most people are using a checkbox. The accepted answer uses a button, but cannot work with several buttons (ex. one at top of page one at bottom). So here is a modification that does both.

HTML

<a href="#" class="check-box-machine my-button-style">Check All</a>

jQuery

var ischecked = false;
$(".check-box-machine").click(function(e) {
    e.preventDefault();
    if (ischecked == false) {
        $("input:checkbox").attr("checked","checked");
        $(".check-box-machine").html("Uncheck All");
        ischecked = true;
    } else {
        $("input:checkbox").removeAttr("checked");
        $(".check-box-machine").html("Check All");
        ischecked = false;
    }
});

This will allow you to have as many buttons as you would like with changing text and checkbox values. I included an e.preventDefault() call because this will stop the page from jumping to the top due to the href="#" part.

$('#' + theMysteryId + '.someClass').each(function() { /* do stuff */ });

Use this.Hide() instead of this.Close()

Here is what I have that helps you and others about markdown checkbox table. Enjoy!

"==" always compare the memory location or object references of the values. equals method always compare the values. But equals also indirectly uses the "==" operator to compare the values.

Integer uses Integer cache to store the values from -128 to +127. If == operator is used to check for any values between -128 to 127 then it returns true. for other than these values it returns false .

Refer the link for some additional info

What you mean is either

SELECT DISTINCT a, b FROM pairs;

or

SELECT a, b FROM pairs GROUP BY a, b;

controller name:

<%= controller.controller_name %>

return => 'users'

action name:

<%= controller.action_name %>

return => 'show'

id:

<%= ActionController::Routing::Routes.recognize_path(request.url)[:id] %>

return => '23'

If we can assume that the H1 is always going to be there, then

div h1+div {...}

but don't be afraid to specify the id of the content div:

#content h1+div {...}

That's about as good as you can get cross-browser right now without resorting to a JavaScript library like jQuery. Using h1+div ensures that only the first div after the H1 gets the style. There are alternatives, but they rely on CSS3 selectors, and thus won't work on most IE installs.

You can look here Can the key in a Java property include a blank character?

for escape equal '=' \u003d

table.whereclause=where id=100

key:[table.whereclause] value:[where id=100]

table.whereclause\u003dwhere id=100

key:[table.whereclause=where] value:[id=100]

table.whereclause\u003dwhere\u0020id\u003d100

key:[table.whereclause=where id=100] value:[]

The reason MyModel::all()->delete() doesn't work is because all() actually fires off the query and returns a collection of Eloquent objects.

You can make use of the truncate method, this works for Laravel 4 and 5:

MyModel::truncate();

That drops all rows from the table without logging individual row deletions.

java_home environment variable should point to the location of the proper version of java installation directory, so that tomcat starts with the right version. for example it you built the project with java 1.7 , then make sure that JAVA_HOME environment variable points to the jdk 1.7 installation directory in your machine.

I had same problem , when i deploy the war in tomcat and run, the link throws the error. But pointing the variable - JAVA_HOME to jdk 1.7 resolved the issue, as my war file was built in java 1.7 environment.

Building on previous answers, I think it's a perfect use case for doing it (simple) context manager style:

import sys

class StdoutRedirection:
    """Standard output redirection context manager"""

    def __init__(self, path):
        self._path = path

    def __enter__(self):
        sys.stdout = open(self._path, mode="w")
        return self

    def __exit__(self, exc_type, exc_val, exc_tb):
        sys.stdout.close()
        sys.stdout = sys.__stdout__

and then:

with StdoutRedirection("path/to/file"):
    print("Hello world")

Also it would be really easy to add some functionality to StdoutRedirection class (e.g. a method that lets you change the path)

Jaap van Hengstum's answer works great however I think it is expensive and if we apply this method on a Button for example, the touch effect is lost since the view is rendered as a bitmap.

For me the best method and the simplest one consists in applying a mask on the view, like that:

@Override
protected void onSizeChanged(int width, int height, int oldWidth, int oldHeight) {
    super.onSizeChanged(width, height, oldWidth, oldHeight);

    float cornerRadius = <whatever_you_want>;
    this.path = new Path();
    this.path.addRoundRect(new RectF(0, 0, width, height), cornerRadius, cornerRadius, Path.Direction.CW);
}

@Override
protected void dispatchDraw(Canvas canvas) {
    if (this.path != null) {
        canvas.clipPath(this.path);
    }
    super.dispatchDraw(canvas);
}

This should do the trick:

SELECT 
    title,
    description,    
    ROUND (   
        (
            LENGTH(description)
            - LENGTH( REPLACE ( description, "value", "") ) 
        ) / LENGTH("value")        
    ) AS count    
FROM <table> 

I had a bootstrap + rails project, and dropdown worked fine. They stopped to works after an update...

This is the solution that fixed the problem, add the following to .js file:

$(document).ready(function() {
    $(".dropdown-toggle").dropdown();
});

Sounds like you are using Microsoft Visual C++. If that is the case, then the most possibility is that you don't compile your two.cpp with one.cpp (one.cpp is the implementation for one.h).

If you are from command line (cmd.exe), then try this first: cl -o two.exe one.cpp two.cpp

If you are from IDE, right click on the project name from Solution Explore. Then choose Add, Existing Item.... Add one.cpp into your project.

There are a bunch of values that can be used to undo CSS rules: initial, unset & revert. More details from the CSS Working Group at W3C:

https://drafts.csswg.org/css-cascade/#defaulting-keywords

As this is 'draft' not all are fully supported, but unset and initial are in most major browsers, revert has less support.

Now it's pretty easy to implement for RecyclerView with ItemTouchHelper. Just override onMove method from ItemTouchHelper.Callback:

 @Override
public boolean onMove(RecyclerView recyclerView, RecyclerView.ViewHolder viewHolder, RecyclerView.ViewHolder target) {
    mMovieAdapter.swap(viewHolder.getAdapterPosition(), target.getAdapterPosition());
    return true;
}

Pretty good tutorial on this can be found at medium.com : Drag and Swipe with RecyclerView

If you are most concerned about code size and/or performance (also for WCET analysis, if you need one), I think this is probably going to be one of the more transparent solutions (for finding and removing elements):

unsigned int l=0, removed=0;

for( unsigned int i=0; i<count; i++ ) {
    if( array[i] != to_remove )
        array[l++] = array[i];
    else
        removed++;
}

count -= removed;

First, install QEMU. On Debian-based distributions like Ubuntu, run:

$ apt-get install qemu

Then run the following command:

$ qemu-img convert -O vmdk imagefile.dd vmdkname.vmdk

I’m assuming a flat disk image is a dd-style image. The convert operation also handles numerous other formats.

For more information about the qemu-img command, see the output of

$ qemu-img -h

In Symfony 4.2+ you have to use the package:

composer require symfony/proxy-manager-bridge

otherwiese you get the exception:

Resetting a non-lazy manager service is not supported. Declare the "doctrine.orm.default_entity_manager" service as lazy.  

Than you can reset the entityManager like this:

services.yaml:

App\Foo:
    - '@doctrine.orm.entity_manager'
    - '@doctrine'

Foo.php:

use Doctrine\Bundle\DoctrineBundle\Registry;
use Doctrine\DBAL\DBALException;
use Doctrine\ORM\EntityManagerInterface;


 try {
    $this->entityManager->persist($entity);
    $this->entityManager->flush();
} catch (DBALException $e) {
    if (!$this->entityManager->isOpen()) {
        $this->entityManager = $this->doctrine->resetManager();
    }
}

var nameCheckBoxList = "myCheckListName";
var selectedValues = $("[name=" + nameCheckBoxList + "]:checked").map(function(){return this.value;});

There is no specialized image component provided in Swing (which is sad in my opinion). So, there are a few options:

1. As @Reimeus said: Use a JLabel with an icon.

2. Create in the window builder a JPanel, that will represent the location of the image. Then add your own custom image component to the JPanel using a few lines of code you will never have to change. They should look like this:

   JImageComponent ic = new JImageComponent(myImageGoesHere);
   imagePanel.add(ic);
   

   where JImageComponent is a self created class that extends JComponent that overrides the paintComponent() method to draw the image.

Problem solved, I've not added the index.html. Which is point out in the web.xml

Note: a project may have more than one web.xml file.

if there are another web.xml in

src/main/webapp/WEB-INF

Then you might need to add another index (this time index.jsp) to

src/main/webapp/WEB-INF/pages/

How about this :

@client = TinyTds::Client.new(
      :adapter => 'mysql2',
      :host => 'host',
      :database => 'siteconfig_development',
      :username => 'username',
      :password => 'password'

sql = "SELECT * FROM users"

result = @client.execute(sql)

results.each do |row|
puts row[0]
end

You need to have TinyTds gem installed, since you didn't specify it in your question I didn't use Active Record
