C++ programs are translated to assembly programs during the generation of machine code from the source code. It would be virtually wrong to say assembly is slower than C++. Moreover, the binary code generated differs from compiler to compiler. So a smart C++ compiler may produce binary code more optimal and efficient than a dumb assembler's code.

However I believe your profiling methodology has certain flaws. The following are general guidelines for profiling:

1. Make sure your system is in its normal/idle state. Stop all running processes (applications) that you started or that use CPU intensively (or poll over the network).
2. Your datasize must be greater in size.
3. Your test must run for something more than 5-10 seconds.
4. Do not rely on just one sample. Perform your test N times. Collect results and calculate the mean or median of the result.

Do the build job on Jenkins first without Sonar configured. Then add Sonar, and run a build job again. Should fix the problem

You need to remove the static from your accessor methods - these methods need to be instance methods and access the instance variables

public class IDCard {
    public String name, fileName;
    public int id;

    public IDCard(final String name, final String fileName, final int id) {
        this.name = name;
        this.fileName = fileName
        this.id = id;
    }

    public String getName() {
        return name;
    }
}

You can the create an IDCard and use the accessor like this:

final IDCard card = new IDCard();
card.getName();

Each time you call new a new instance of the IDCard will be created and it will have it's own copies of the 3 variables.

If you use the static keyword then those variables are common across every instance of IDCard.

A couple of things to bear in mind:

1. don't add useless comments - they add code clutter and nothing else.
2. conform to naming conventions, use lower case of variable names - name not Name.

In Java, when you write:

Object objectA = new Object();
Object objectB = objectA;

objectA and objectB are the same and point to the same reference. Changing one will change the other. So if you change the state of objectA (not its reference) objectB will reflect that change too.

However, if you write:

objectA = new Object()

Then objectB is still pointing to the first object you created (original objectA) while objectA is now pointing to a new Object.

The root cause is that when debugging the java debug interface will call the toString() of your class to show the class information in the pop up box, so if the toString method is not defined correctly, this may happen.

NULL-safe condition would looks like:

select * from table
where NOT (tester <=> 'username')

Use this one, I've written this to my app,

<?xml version="1.0" encoding="utf-8"?>
<!--  res/drawable/rounded_edittext.xml -->
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle" android:padding="10dp">
    <solid android:color="#882C383E"/>
    <corners
        android:bottomRightRadius="5dp"
        android:bottomLeftRadius="5dp"
        android:topLeftRadius="5dp"
        android:topRightRadius="5dp"/>
</shape>

I would suggest editing the /etc/default/jenkins

vi /etc/default/jenkins

And changing the $JENKINS_HOME variable (around line 23) to

JENKINS_HOME=/home/jenkins

Then restart the Jenkins with usual

/etc/init.d/jenkins start

Cheers!

select top 10 * from
(
    select distinct p.id, ....
)

will work.

There are a couple of ways:

If you want to use raw Javascript (without a helper like JQuery), then you could do something like:

var link = "http://google.com";
var element = document.createElement("a");
element.setAttribute("href", link);
element.innerHTML = "your text";

// and append it to where you'd like it to go:
document.body.appendChild(element);

The other method is to write the link directly into the document:

document.write("<a href='" + link + "'>" + text + "</a>");

Kruskal can have better performance if the edges can be sorted in linear time, or are already sorted.

Prim's better if the number of edges to vertices is high.

If you are printing to stderr using the stdio library, a call to fflush(stderr) should flush the buffer and get you real-time logging.

Why don't you consider www.cameraftp.com? it supports image upload and online viewer

I had this problem in a list of post in a blog, the post are in a view inside a foreach, then is difficult select it in javascript, and the problem of post method and token also exists.

This the code for javascript at the end of the view, I generate the token in javascript functión inside the view and not in a external js file, then is easy use php lavarel to generate it with csrf_token() function, and send the "delete" method directly in params. You can see that I don´t use in var route: {{ route('post.destroy', $post->id}} because I don´t know the id I want delete until someone click in destroy button, if you don´t have this problem you can use {{ route('post.destroy', $post->id}} or other like this.

  $(function(){
    $(".destroy").on("click", function(){
         var vid = $(this).attr("id");
         var v_token = "{{csrf_token()}}";
         var params = {_method: 'DELETE', _token: v_token};
         var route = "http://imagica.app/posts/" + vid + "";
    $.ajax({
         type: "POST",
         url: route,
         data: params
    });
   });
  });

and this the code of content in view (inside foreach there are more forms and the data of each post but is not inportant by this example), you can see I add a class "delete" to button and I call class in javascript.

      @foreach($posts as $post)
          <form method="POST">
            <button id="{{$post->id}}" class="btn btn-danger btn-sm pull-right destroy" type="button" >eliminar</button>
          </form>
      @endforeach

You have to add a ToolTip control to your form first. Then you can set the text it should display for other controls.

Here's a screenshot showing the designer after adding a ToolTip control which is named toolTip1:

If you are developing a command line application, you can also use Console.ReadLine() at the end of your code to wait for the 'Enter' keypress before closing the console window so that you can read your output.

This my function for select box placeholder.

HTML

<select name="country" id="country">
  <option value="" disabled selected>Country</option>
  <option value="c1">England</option>
  <option value="c2">Russia</option>
  <option value="c3">USA</option>
</select>

jQuery

     jQuery(function($) {
      /*function for placeholder select*/
      function selectPlaceholder(selectID){
        var selected = $(selectID + ' option:selected');
        var val = selected.val();
        $(selectID + ' option' ).css('color', '#333');
        selected.css('color', '#999');
        if (val == "") {
          $(selectID).css('color', '#999');
        };
        $(selectID).change(function(){
          var val = $(selectID + ' option:selected' ).val();
          if (val == "") {
            $(selectID).css('color', '#999');
          }else{
            $(selectID).css('color', '#333');
          };
        });
      };

      selectPlaceholder('#country');

    });

You can leverage NavigableMap interface that may be accessed and traversed in either ascending or descending key order. This interface is intended to supersede the SortedMap interface. The Navigable map is usually sorted according to the natural ordering of its keys, or by a Comparator provided at map creation time.

There are three most useful implementations of it: TreeMap, ImmutableSortedMap, and ConcurrentSkipListMap.

TreeMap example:

TreeMap<String, Integer> users = new TreeMap<String, Integer>();
users.put("Bob", 1);
users.put("Alice", 2);
users.put("John", 3);

for (String key: users.keySet()) {
  System.out.println(key + " (ID = "+ users.get(key) + ")");
}

Output:

Alice (ID = 2)
Bob (ID = 1)
John (ID = 3)

<a href="/index2.php?option=com_jumi&amp;fileid=3&amp;Itemid=11"
   onclick="window.open(this.href,'targetWindow',
                                   `toolbar=no,
                                    location=no,
                                    status=no,
                                    menubar=no,
                                    scrollbars=yes,
                                    resizable=yes,
                                    width=SomeSize,
                                    height=SomeSize`);
 return false;">Popup link</a>

Where width and height are pixels without units (width=400 not width=400px).

In most browsers it will not work if it is not written without line breaks, once the variables are setup have everything in one line:

<a href="/index2.php?option=com_jumi&amp;fileid=3&amp;Itemid=11" onclick="window.open(this.href,'targetWindow','toolbar=no,location=no,status=no,menubar=no,scrollbars=yes,resizable=yes,width=SomeSize,height=SomeSize'); return false;">Popup link</a> 

In case of Request to a REST Service:

You need to allow the CORS (cross origin sharing of resources) on the endpoint of your REST Service with Spring annotation:

@CrossOrigin(origins = "http://localhost:8080")

Very good tutorial: https://spring.io/guides/gs/rest-service-cors/

Try using sed as mentioned on http://linuxcommando.blogspot.com/2008/03/using-sed-to-extract-lines-in-text-file.html. For example use

sed '2,4!d' somefile.txt

to print from the second line to the fourth line of somefile.txt. (And don't forget to check http://www.grymoire.com/Unix/Sed.html, sed is a wonderful tool.)

I don't know if this will help, but here's the SWT FAQ question How do I use Mozilla as the Browser's underlying renderer?

Edit: Having researched this further, it sounds like this isn't possible in Eclipse 3.4, but may be slated for a later release.

These look the same as their real counterparts in Safari, Chrome, and Firefox. They degrade gracefully and look OK in Opera and IE9, too.

If you want to use calc in your CSS file use a polyfill like PolyCalc. Should be light enough to work on mobile browsers (e.g. below iOS 6 and below Android 4.4 phones).

The sqlalchemy docs have a writeup on the performance of various techniques that can be used for bulk inserts:

ORMs are basically not intended for high-performance bulk inserts - this is the whole reason SQLAlchemy offers the Core in addition to the ORM as a first-class component.

For the use case of fast bulk inserts, the SQL generation and execution system that the ORM builds on top of is part of the Core. Using this system directly, we can produce an INSERT that is competitive with using the raw database API directly.

Alternatively, the SQLAlchemy ORM offers the Bulk Operations suite of methods, which provide hooks into subsections of the unit of work process in order to emit Core-level INSERT and UPDATE constructs with a small degree of ORM-based automation.

The example below illustrates time-based tests for several different methods of inserting rows, going from the most automated to the least. With cPython 2.7, runtimes observed:

If you have to click OK after entering your passcode, this command will unlock your phone:

adb shell input text XXXX && adb shell input keyevent 66

Where

• XXXX is your passcode.
• 66 is keycode of button OK.
• adb shell input text XXXX will enter your passcode.
• adb shell input keyevent 66 will simulate click the OK button

Today (2.5 years after this answer) you can safely use Array.forEach. As @ricosrealm suggests, decodeURIComponent was used in this function.

function getJsonFromUrl(url) {
  if(!url) url = location.search;
  var query = url.substr(1);
  var result = {};
  query.split("&").forEach(function(part) {
    var item = part.split("=");
    result[item[0]] = decodeURIComponent(item[1]);
  });
  return result;
}

actually it's not that simple, see the peer-review in the comments, especially:

• hash based routing (@cmfolio)
• array parameters (@user2368055)
• proper use of decodeURIComponent and non-encoded = (@AndrewF)
• non-encoded + (added by me)

For further details, see MDN article and RFC 3986.

Maybe this should go to codereview SE, but here is safer and regexp-free code:

function getJsonFromUrl(url) {
  if(!url) url = location.href;
  var question = url.indexOf("?");
  var hash = url.indexOf("#");
  if(hash==-1 && question==-1) return {};
  if(hash==-1) hash = url.length;
  var query = question==-1 || hash==question+1 ? url.substring(hash) : 
  url.substring(question+1,hash);
  var result = {};
  query.split("&").forEach(function(part) {
    if(!part) return;
    part = part.split("+").join(" "); // replace every + with space, regexp-free version
    var eq = part.indexOf("=");
    var key = eq>-1 ? part.substr(0,eq) : part;
    var val = eq>-1 ? decodeURIComponent(part.substr(eq+1)) : "";
    var from = key.indexOf("[");
    if(from==-1) result[decodeURIComponent(key)] = val;
    else {
      var to = key.indexOf("]",from);
      var index = decodeURIComponent(key.substring(from+1,to));
      key = decodeURIComponent(key.substring(0,from));
      if(!result[key]) result[key] = [];
      if(!index) result[key].push(val);
      else result[key][index] = val;
    }
  });
  return result;
}

This function can parse even URLs like

var url = "?foo%20e[]=a%20a&foo+e[%5Bx%5D]=b&foo e[]=c";
// {"foo e": ["a a",  "c",  "[x]":"b"]}

var obj = getJsonFromUrl(url)["foo e"];
for(var key in obj) { // Array.forEach would skip string keys here
  console.log(key,":",obj[key]);
}
/*
  0 : a a
  1 : c
  [x] : b
*/

You could process the file while being read by using streams. It's just like using buffers but with a more convenient API.

var fs = require('fs');
function searchReplaceFile(regexpFind, replace, cssFileName) {
    var file = fs.createReadStream(cssFileName, 'utf8');
    var newCss = '';

    file.on('data', function (chunk) {
        newCss += chunk.toString().replace(regexpFind, replace);
    });

    file.on('end', function () {
        fs.writeFile(cssFileName, newCss, function(err) {
            if (err) {
                return console.log(err);
            } else {
                console.log('Updated!');
            }
    });
});

searchReplaceFile(/foo/g, 'bar', 'file.txt');

Select multiple lines by clicking first line then holding shift and clicking last line. Then press:

CTRL+SHIFT+L

or on MAC: CMD+SHIFT+L (as per comments)

Alternatively you can select lines and go to SELECTION MENU >> SPLIT INTO LINES.

Now you can edit multiple lines, move cursors etc. for all selected lines.

My iPad was 8.0, but i had deployment target set to 8.1. I changed the deployment target in build settings, and immediately, the ipad moved out of the "ineligible" category. (I am on Yosemite and XCode 6.1)

Try this instead:

String scheme = req.getScheme();             
String serverName = req.getServerName(); 
int serverPort = req.getServerPort();    
String uri = (String) req.getAttribute("javax.servlet.forward.request_uri");
String prmstr = (String) req.getAttribute("javax.servlet.forward.query_string");
String url = scheme + "://" +serverName + ":" + serverPort + uri + "?" + prmstr;

Note: You can't get HREF anchor from your url. Example, if you have url "toc.html#top" then you can get only "toc.html"

Note: req.getAttribute("javax.servlet.forward.request_uri") work only in JSP. if you run this in controller before JSP then result is null

You can use code for both variant:

public static String getCurrentUrl(HttpServletRequest req) {
    String url = getCurrentUrlWithoutParams(req);
    String prmstr = getCurrentUrlParams(req);
    url += "?" + prmstr;
    return url;
}

public static String getCurrentUrlParams(HttpServletRequest request) {
    return StringUtil.safeString(request.getQueryString());
}

public static String getCurrentUrlWithoutParams(HttpServletRequest request) {
    String uri = (String) request.getAttribute("javax.servlet.forward.request_uri");
    if (uri == null) {
        return request.getRequestURL().toString();
    }
    String scheme = request.getScheme();
    String serverName = request.getServerName();
    int serverPort = request.getServerPort();
    String url = scheme + "://" + serverName + ":" + serverPort + uri;
    return url;
}

I had to accept the XCode license after my first install before I could run it. You can run the following to get the license prompt via command line. You have to type agree and confirm as well.

sudo xcodebuild -license

It looks like people answered the first part of your question (use application/json).

For the second part: It is perfectly legal to send query parameters in a HTTP POST Request.

Example:

POST /members?id=1234 HTTP/1.1
Host: www.example.com
Content-Type: application/json

{"email":"[email protected]"}

Query parameters are commonly used in a POST request to refer to an existing resource. The above example would update the email address of an existing member with the id of 1234.

You could use the xpath :

//div[@class="measure-tab" and .//span[contains(., "someText")]]

Input :

<root>
<div class="measure-tab">
  <td> someText</td>
</div>
<div class="measure-tab">
  <div>
    <div2>
       <span>someText2</span>
   </div2>
  </div>
</div>
</root>

Output :

    Element='<div class="measure-tab">
  <div>
    <div2>
      <span>someText2</span>
    </div2>
  </div>
</div>'

if (xyz[kKeyToCheck])
  NSLog(@"Key: %@, has Value: %@", kKeyToCheck, xyz[kKeyToCheck]);
else
 NSLog(@"Key pair do not exits for key: %@", kKeyToCheck); 

For me the issue was about a comma not in the filename but as below: -

Response.ok(streamingOutput,MediaType.APPLICATION_OCTET_STREAM_TYPE).header("content-disposition", "attachment, filename=your_file_name").build();

I accidentally put a comma after attachment. Got it resolved by replacing comma with a semicolon.

If value is a string in that format and you'd like to convert it into a DateTime object, you can use DateTime.ParseExact static method:

DateTime.ParseExact(value, format, CultureInfo.CurrentCulture);

Example:

string value = "12/12";
var myDate = DateTime.ParseExact(value, "MM/yy", System.Globalization.CultureInfo.InvariantCulture, System.Globalization.DateTimeStyles.None);

Console.WriteLine(myDate.ToShortDateString());

Result:

2012-12-01

If you are using unix, you need to write a shellscript to run you java batch first.

After that, in unix, you run this command "crontab -e" to edit crontab script. In order to configure crontab, please refer to this article http://www.thegeekstuff.com/2009/06/15-practical-crontab-examples/

Save your crontab setting. Then wait for the time to come, program will run automatically.

Find out the name of the inputs used on the websites form for usernames <...name=username.../> and passwords <...name=password../> and replace them in the script below. Also replace the URL to point at the desired site to log into.

login.py

#!/usr/bin/env python

import requests
from requests.packages.urllib3.exceptions import InsecureRequestWarning
requests.packages.urllib3.disable_warnings(InsecureRequestWarning)
payload = { 'username': '[email protected]', 'password': 'blahblahsecretpassw0rd' }
url = 'https://website.com/login.html'
requests.post(url, data=payload, verify=False)

The use of disable_warnings(InsecureRequestWarning) will silence any output from the script when trying to log into sites with unverified SSL certificates.

Extra:

To run this script from the command line on a UNIX based system place it in a directory, i.e. home/scripts and add this directory to your path in ~/.bash_profile or a similar file used by the terminal.

# Custom scripts
export CUSTOM_SCRIPTS=home/scripts
export PATH=$CUSTOM_SCRIPTS:$PATH

Then create a link to this python script inside home/scripts/login.py

ln -s ~/home/scripts/login.py ~/home/scripts/login

Close your terminal, start a new one, run login

My impression is that R CMD BATCH is a bit of a relict. In any case, the more recent Rscript executable (available on all platforms), together with commandArgs() makes processing command line arguments pretty easy.

As an example, here is a little script -- call it "myScript.R":

## myScript.R
args <- commandArgs(trailingOnly = TRUE)
rnorm(n=as.numeric(args[1]), mean=as.numeric(args[2]))

And here is what invoking it from the command line looks like

> Rscript myScript.R 5 100
[1]  98.46435 100.04626  99.44937  98.52910 100.78853

Edit:

Not that I'd recommend it, but ... using a combination of source() and sink(), you could get Rscript to produce an .Rout file like that produced by R CMD BATCH. One way would be to create a little R script -- call it RscriptEcho.R -- which you call directly with Rscript. It might look like this:

## RscriptEcho.R
args <- commandArgs(TRUE)
srcFile <- args[1]
outFile <- paste0(make.names(date()), ".Rout")
args <- args[-1]

sink(outFile, split = TRUE)
source(srcFile, echo = TRUE)

To execute your actual script, you would then do:

Rscript RscriptEcho.R myScript.R 5 100
[1]  98.46435 100.04626  99.44937  98.52910 100.78853

which will execute myScript.R with the supplied arguments and sink interleaved input, output, and messages to a uniquely named .Rout.

Edit2:
You can run Rscript verbosely and place the verbose output in a file.

Rscript --verbose myScript.R 5 100 > myScript.Rout

Well, as colon is kind of special symbol, but is part of method signature, it is possible to exted the NSString with category to add this non-idiomatic style of string concatenation:

[@"This " : @"feels " : @"almost like " : @"concatenation with operators"];

You can define as many colon separated arguments as you find useful... ;-)

For a good measure, I've also added concat: with variable arguments that takes nil terminated list of strings.

//  NSString+Concatenation.h

All of the examples here (with the exception of rockacola's) require that the user physically click on the window to define focus. This isn't ideal, so .hover() is the better choice:

$(window).hover(function(event) {
    if (event.fromElement) {
        console.log("inactive");
    } else {
        console.log("active");
    }
});

This'll tell you when the user has their mouse on the screen, though it still won't tell you if it's in the foreground with the user's mouse elsewhere.

You probably want an extra wrapper. use a div for the background and position it below your content..

I put together start to finish code of a hypothetical experiment with ten measurement replicated three times. Just for fun with the help of other stackoverflowers. Thank you... Obviously loops are an option as applycan be used but I like to see what happens.

#Create fake data
x <-rep(1:10, each =3)
y <- rnorm(30, mean=4,sd=1)

#Loop to get standard deviation from data
sd.y = NULL
for(i in 1:10){
  sd.y[i] <- sd(y[(1+(i-1)*3):(3+(i-1)*3)])
}
sd.y<-rep(sd.y,each = 3)

#Loop to get mean from data
mean.y = NULL
for(i in 1:10){
  mean.y[i] <- mean(y[(1+(i-1)*3):(3+(i-1)*3)])
}
mean.y<-rep(mean.y,each = 3)

#Put together the data to view it so far
data <- cbind(x, y, mean.y, sd.y)

#Make an empty matrix to fill with shrunk data
data.1 = matrix(data = NA, nrow=10, ncol = 4)
colnames(data.1) <- c("X","Y","MEAN","SD")

#Loop to put data into shrunk format
for(i in 1:10){
  data.1[i,] <- data[(1+(i-1)*3),]
}

#Create atomic vectors for arrows
x <- data.1[,1]
mean.exp <- data.1[,3]
sd.exp <- data.1[,4]

#Plot the data
plot(x, mean.exp, ylim = range(c(mean.exp-sd.exp,mean.exp+sd.exp)))
abline(h = 4)
arrows(x, mean.exp-sd.exp, x, mean.exp+sd.exp, length=0.05, angle=90, code=3)

You need to upgrade your Java version to Java 8.

Download latest Java archive

Download latest Java SE Development Kit 8 release from its official download page or use following commands to download from the shell.

For 64 bit

 # cd /opt/

 # wget --no-cookies --no-check-certificate --header "Cookie: gpw_e24=http%3A%2F%2Fwww.oracle.com%2F; oraclelicense=accept-securebackup-cookie" "http://download.oracle.com/otn-pub/java/jdk/8u51-b16/jdk-8u51-linux-x64.tar.gz"

 # tar xzf jdk-8u51-linux-x64.tar.gz

For 32 bit

 # cd /opt/

 # wget --no-cookies --no-check-certificate --header "Cookie: gpw_e24=http%3A%2F%2Fwww.oracle.com%2F; oraclelicense=accept-securebackup-cookie" "http://download.oracle.com/otn-pub/java/jdk/8u51-b16/jdk-8u51-linux-i586.tar.gz"

  # tar xzf jdk-8u51-linux-i586.tar.gz

Note: If the above wget command doesn’t not work for you, watch this example video to download the Java source archive using the terminal.

Install Java with alternatives

After extracting the archive file, use the alternatives command to install it. The alternatives command is available in the chkconfig package.

 # cd /opt/jdk1.8.0_51/

 # alternatives --install /usr/bin/java java /opt/jdk1.8.0_51/bin/java 2

 # alternatives --config java

At this point Java 8 has been successfully installed on your system. We also recommend to setup javac and jar commands path using alternatives:

 # alternatives --install /usr/bin/jar jar /opt/jdk1.8.0_51/bin/jar 2

 # alternatives --install /usr/bin/javac javac /opt/jdk1.8.0_51/bin/javac 2

 # alternatives --set jar /opt/jdk1.8.0_51/bin/jar

 # alternatives --set javac /opt/jdk1.8.0_51/bin/javac

Check installed Java version

Check the installed version of Java using the following command.

root@tecadmin ~# java -version

java version "1.8.0_51"
Java(TM) SE Runtime Environment (build 1.8.0_51-b16)
Java HotSpot(TM) 64-Bit Server VM (build 25.51-b03, mixed mode)

Configuring Environment Variables

Most of Java-based applications use environment variables to work. Set the Java environment variables using the following commands:

Setup JAVA_HOME Variable

# export JAVA_HOME=/opt/jdk1.8.0_51
Setup JRE_HOME Variable

# export JRE_HOME=$JAVA_HOME/jre
Setup PATH Variable

# export PATH=$JAVA_HOME/bin:$JRE_HOME/bin:$PATH

Note that the change to the PATH variable put the new Java bin folders first so that they override any existing java/bins in the path. It is a bit sloppy to leave two java/bin folders in your path so you should be advised to clean those up as a separate task.

Also, put all above environment variables in the /etc/environment file for auto loading on system boot.

In pandas 16.2, I had to do pd.DataFrame.from_records(d) to get this to work.

The simplest way to do that is using plain HTML.

You can use one of these ways:

<embed type="text/html" src="header.html">

or:

<object name="foo" type="text/html" data="header.html"></object>

I want columns One and Two to shrink/grow to fit rather than being fixed.

Have you tried: flex-basis: auto

or this:

flex: 1 1 auto, which is short for:

• flex-grow: 1 (grow proportionally)
• flex-shrink: 1 (shrink proportionally)
• flex-basis: auto (initial size based on content size)

or this:

main > section:first-child {
    flex: 1 1 auto;
    overflow-y: auto;
}

main > section:nth-child(2) {
    flex: 1 1 auto;
    overflow-y: auto;
}

main > section:last-child {
    flex: 20 1 auto;
    display: flex;
    flex-direction: column;  
}

revised demo

Related:

• Make flex items take content width, not width of parent container
• Make flex container take width of content, not width 100%

This worked perfectly for me:

$ git reset -- foo/bar.txt
$ git checkout foo/bar.txt

You can edit

/vendor/twig/twig/lib/Twig/Extension/Debug.php

and change the var_dump() functions to \Doctrine\Common\Util\Debug::dump()

Note that since git1.7.11 ([ANNOUNCE] Git 1.7.11.rc1 and release note, June 2012) mentions:

"git push --recurse-submodules" learned to optionally look into the histories of submodules bound to the superproject and push them out.

Probably done after this patch and the --on-demand option:

recurse-submodules=<check|on-demand>::

Make sure all submodule commits used by the revisions to be pushed are available on a remote tracking branch.

• If check is used, it will be checked that all submodule commits that changed in the revisions to be pushed are available on a remote.
  Otherwise the push will be aborted and exit with non-zero status.
• If on-demand is used, all submodules that changed in the revisions to be pushed will be pushed.
  If on-demand was not able to push all necessary revisions it will also be aborted and exit with non-zero status.

So you could push everything in one go with (from the parent repo) a:

git push --recurse-submodules=on-demand

This option only works for one level of nesting. Changes to the submodule inside of another submodule will not be pushed.

With git 2.7 (January 2016), a simple git push will be enough to push the parent repo... and all its submodules.

See commit d34141c, commit f5c7cd9 (03 Dec 2015), commit f5c7cd9 (03 Dec 2015), and commit b33a15b (17 Nov 2015) by Mike Crowe (mikecrowe).
^{(Merged by Junio C Hamano -- gitster -- in commit 5d35d72, 21 Dec 2015)}

push: add recurseSubmodules config option

The --recurse-submodules command line parameter has existed for some time but it has no config file equivalent.

Following the style of the corresponding parameter for git fetch, let's invent push.recurseSubmodules to provide a default for this parameter.
This also requires the addition of --recurse-submodules=no to allow the configuration to be overridden on the command line when required.

The most straightforward way to implement this appears to be to make push use code in submodule-config in a similar way to fetch.

The git config doc now include:

push.recurseSubmodules:

Make sure all submodule commits used by the revisions to be pushed are available on a remote-tracking branch.

• If the value is 'check', then Git will verify that all submodule commits that changed in the revisions to be pushed are available on at least one remote of the submodule. If any commits are missing, the push will be aborted and exit with non-zero status.
• If the value is 'on-demand' then all submodules that changed in the revisions to be pushed will be pushed. If on-demand was not able to push all necessary revisions it will also be aborted and exit with non-zero status. -
• If the value is 'no' then default behavior of ignoring submodules when pushing is retained.

You may override this configuration at time of push by specifying '--recurse-submodules=check|on-demand|no'.

So:

git config push.recurseSubmodules on-demand
git push

Git 2.12 (Q1 2017)

git push --dry-run --recurse-submodules=on-demand will actually work.

See commit 0301c82, commit 1aa7365 (17 Nov 2016) by Brandon Williams (mbrandonw).
^{(Merged by Junio C Hamano -- gitster -- in commit 12cf113, 16 Dec 2016)}

push run with --dry-run doesn't actually (Git 2.11 Dec. 2016 and lower/before) perform a dry-run when push is configured to push submodules on-demand.
Instead all submodules which need to be pushed are actually pushed to their remotes while any updates for the superproject are performed as a dry-run.
This is a bug and not the intended behaviour of a dry-run.

Teach push to respect the --dry-run option when configured to recursively push submodules 'on-demand'.
This is done by passing the --dry-run flag to the child process which performs a push for a submodules when performing a dry-run.

And still in Git 2.12, you now havea "--recurse-submodules=only" option to push submodules out without pushing the top-level superproject.

See commit 225e8bf, commit 6c656c3, commit 14c01bd (19 Dec 2016) by Brandon Williams (mbrandonw).
^{(Merged by Junio C Hamano -- gitster -- in commit 792e22e, 31 Jan 2017)}

Have you tried using rclone.org?

With rclone you could do something like

rclone copy "${source}/${subfolder}/" "${target}/${subfolder}/" --progress --multi-thread-streams=N

where --multi-thread-streams=N represents the number of threads you wish to spawn.

In cpp, you need to pay special attention to string types when using execvp:

#include <iostream>
#include <string>
#include <cstring>
#include <stdio.h>
#include <unistd.h>
using namespace std;

const size_t MAX_ARGC = 15; // 1 command + # of arguments
char* argv[MAX_ARGC + 1]; // Needs +1 because of the null terminator at the end
// c_str() converts string to const char*, strdup converts const char* to char*
argv[0] = strdup(command.c_str());

// start filling up the arguments after the first command
size_t arg_i = 1;
while (cin && arg_i < MAX_ARGC) {
    string arg;
    cin >> arg;
    if (arg.empty()) {
        argv[arg_i] = nullptr;
        break;
    } else {
        argv[arg_i] = strdup(arg.c_str());
    }
    ++arg_i;
}

// Run the command with arguments
if (execvp(command.c_str(), argv) == -1) {
    // Print error if command not found
    cerr << "command '" << command << "' not found\n";
}

Reference: execlp?execvp?????

If you want local time to set, add the following text in application.rb

config.time_zone = 'Chennai'

# WARNING: This changes the way times are stored in the database (not recommended)
config.active_record.default_timezone = :local

According to the CSS Flexible Box Layout Module, you can declare the a element as a flex container (see figure) and use align-items to vertically align text along the cross axis (which is perpendicular to the main axis).

All you need to do is:

display: flex;
align-items: center;

I had this issue and noticed that it was printing my PATH with two sets of double-quotes. I worked around the problem by adding the following to Line 1959 of:

Obviously not the best fix but it got me through the day.

Well it depends on what you have in your table.

its one of the following If you have only one table

var count = $('#gvPerformanceResult tr').length;

If you are concerned about sub tables but this wont work with tbody and thead (if you use them)

var count = $('#gvPerformanceResult>tr').length;

Where by this will work (but is quite frankly overkill.)

var count = $('#gvPerformanceResult>tbody>tr').length;

Use the datetime method and the operator < and its kin.

>>> from datetime import datetime, timedelta
>>> past = datetime.now() - timedelta(days=1)
>>> present = datetime.now()
>>> past < present
True
>>> datetime(3000, 1, 1) < present
False
>>> present - datetime(2000, 4, 4)
datetime.timedelta(4242, 75703, 762105)

Javascript has a dedicated operator for this: unary negation.

TL;DR: It's the minus sign!

To negate a number, simply prefix it with - in the most intuitive possible way. No need to write a function, use Math.abs() multiply by -1 or use the bitwise operator.

Unary negation works on number literals:

let a = 10;  // a is `10`
let b = -10; // b is `-10`

It works with variables too:

let x = 50;
x = -x;      // x is now `-50`

let y = -6;
y = -y;      // y is now `6`

You can even use it multiple times if you use the grouping operator (a.k.a. parentheses:

l = 10;       // l is `10`
m = -10;      // m is `-10`
n = -(10);    // n is `-10`
o = -(-(10)); // o is `10`
p = -(-10);   // p is `10` (double negative makes a positive)

All of the above works with a variable as well.

You had thead in your selector, but there is no thead in your table. Also you had your selectors backwards. As you mentioned above, you wanted to be adding the tr class to the th, not vice-versa (although your comment seems to contradict what you wrote up above).

$('tr th').each(function(index){     if($('tr td').eq(index).attr('class') != ''){         // get the class of the td         var tdClass = $('tr td').eq(index).attr('class');         // add it to this th         $(this).addClass(tdClass );     } });

import urllib, urllib2, cookielib

username = 'myuser'
password = 'mypassword'

cj = cookielib.CookieJar()
opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cj))
login_data = urllib.urlencode({'username' : username, 'j_password' : password})
opener.open('http://www.example.com/login.php', login_data)
resp = opener.open('http://www.example.com/hiddenpage.php')
print resp.read()

resp.read() is the straight html of the page you want to open, and you can use opener to view any page using your session cookie.

In practice, the difference is in the location where the preprocessor searches for the included file.

For #include <filename> the preprocessor searches in an implementation dependent manner, normally in search directories pre-designated by the compiler/IDE. This method is normally used to include standard library header files.

For #include "filename" the preprocessor searches first in the same directory as the file containing the directive, and then follows the search path used for the #include <filename> form. This method is normally used to include programmer-defined header files.

A more complete description is available in the GCC documentation on search paths.

Key class:

@Embeddable
@Access (AccessType.FIELD)
public class EntryKey implements Serializable {

    public EntryKey() {
    }

    public EntryKey(final Long id, final Long version) {
        this.id = id;
        this.version = version;
    }

    public Long getId() {
        return this.id;
    }

    public void setId(Long id) {
        this.id = id;
    }

    public Long getVersion() {
        return this.version;
    }

    public void setVersion(Long version) {
        this.version = version;
    }

    public boolean equals(Object other) {
        if (this == other)
            return true;
        if (!(other instanceof EntryKey))
            return false;
        EntryKey castOther = (EntryKey) other;
        return id.equals(castOther.id) && version.equals(castOther.version);
    }

    public int hashCode() {
        final int prime = 31;
        int hash = 17;
        hash = hash * prime + this.id.hashCode();
        hash = hash * prime + this.version.hashCode();
        return hash;
    }

    @Column (name = "ID")
    private Long id;
    @Column (name = "VERSION")
    private Long operatorId;
}

Entity class:

@Entity
@Table (name = "YOUR_TABLE_NAME")
public class Entry implements Serializable {

    @EmbeddedId
    public EntryKey getKey() {
        return this.key;
    }

    public void setKey(EntryKey id) {
        this.id = id;
    }

    ...

    private EntryKey key;
    ...
}

How can I duplicate it with another Version?

You can detach entity which retrieved from provider, change the key of Entry and then persist it as a new entity.

Here's a different way to do it, but it's only useful if SecondDate is a variable you're passing in:

DateTime startDate = SecondDate.Date;
DateTime endDate = startDate.AddDays(1).AddTicks(-1);
...
e => e.FirstDate.Value >= startDate && e.FirstDate.Value <= endDate

I think that should work

"Accidental" form submission was exactly the problem I was having. I just removed the FORM tags altogether and that seems to fix the problem. Thank you, everybody!

__construct is always called when creating new objects or they are invoked when initialization takes place.it is suitable for any initialization that the object may need before it is used. __construct method is the first method executed in class.

    class Test
    {
      function __construct($value1,$value2)
      {
         echo "Inside Construct";
         echo $this->value1;
         echo $this->value2;
      }
    }

//
  $testObject  =  new Test('abc','123');

Use a non-consuming regular expression.

The typical (i.e. Perl/Java) notation is:

(?=expr)

This means "match expr but after that continue matching at the original match-point."

You can do as many of these as you want, and this will be an "and." Example:

(?=match this expression)(?=match this too)(?=oh, and this)

You can even add capture groups inside the non-consuming expressions if you need to save some of the data therein.

Here is simplified tutorial:

Practical UML

For more I recommend to get some literature.

You can use xp_dirtree

It takes three parameters:

Path of a Root Directory, Depth up to which you want to get files and folders and the last one is for showing folders only or both folders and files.

EXAMPLE: EXEC xp_dirtree 'C:\', 2, 1

Because SQL Server performs integer division. Try this:

select 1 * 1.0 / 3

This is helpful when you pass integers as params.

select x * 1.0 / y

Just call getResources().getDimensionPixelSize(R.dimen.your_dimension) to convert from dp units to pixels

This works fine .. here btnAddCat is button id

$('#btnAddCat').click(function(){
        var eventCategory=$("input[name=txtCategory]").val();
        alert(eventCategory);
    });

Heavily based on Doin's #4 code, the below example simplifies that code a great bit utilising document.write instead of src in the iframe to support CORS. Also only focuses on busting the browser cache, not reloading every image on the page.

Below is written in typescript and uses the angular $q promise library, just fyi, but should be easy enough to port to vanilla javascript. Method is meant to live inside a typescript class.

Returns a promise that will be resolved when the iframe has completed reloading. Not heavily tested, but works well for us.

    mmForceImgReload(src: string): ng.IPromise<void> {
        var deferred = $q.defer<void>();
        var iframe = window.document.createElement("iframe");

        var firstLoad = true;
        var loadCallback = (e) => {
            if (firstLoad) {
                firstLoad = false;
                iframe.contentWindow.location.reload(true);
            } else {
                if (iframe.parentNode) iframe.parentNode.removeChild(iframe);
                deferred.resolve();
            }
        }
        iframe.style.display = "none";
        window.parent.document.body.appendChild(iframe);
        iframe.addEventListener("load", loadCallback, false);
        iframe.addEventListener("error", loadCallback, false);
        var doc = iframe.contentWindow.document;
        doc.open();
        doc.write('<html><head><title></title></head><body><img src="' + src + '"></body></html>');
        doc.close();
        return deferred.promise;
    }

You can add new function to your jQuery library by adding these line on your own script file and you can easily use fadeSlideRight() and fadeSlideLeft().

Note: you can change width of animation as you like instance of 750px.

$.fn.fadeSlideRight = function(speed,fn) {
    return $(this).animate({
        'opacity' : 1,
        'width' : '750px'
    },speed || 400, function() {
        $.isFunction(fn) && fn.call(this);
    });
}

$.fn.fadeSlideLeft = function(speed,fn) {
    return $(this).animate({
        'opacity' : 0,
        'width' : '0px'
    },speed || 400,function() {
        $.isFunction(fn) && fn.call(this);
    });
}

I would suggest hinterland extension.

In other answers I couldn't find the method for how to install it from pip, so this is how you install it.

First, install jupyter contrib nbextensions by running

pip install jupyter_contrib_nbextensions

Next install js and css file for jupyter by running

jupyter contrib nbextension install --user

and at the end run,

jupyter nbextension enable hinterland/hinterland

The output of last command will be

Enabling notebook extension hinterland/hinterland...

There is a way to increase character using ascii_letters from string package which ascii_letters is a string that contains all English alphabet, uppercase and lowercase:

>>> from string import ascii_letters
>>> ascii_letters[ascii_letters.index('a') + 1]
'b'
>>> ascii_letters
'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ'

Also it can be done manually;

>>> letters = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ'
>>> letters[letters.index('c') + 1]
'd'

I've got this error when I ran composer install inside my PHP DOCKER container, It's a memory issue. Solved by increasing SWAP memory in DOCKER PREFERENCES from 512MB to 1.5GB

To do that:

Docker -> Preferences -> Rousources

Regarding the error itself, let is used to declare local variables that exist in block scopes instead of function scopes. It's also more strict than var, so you can't do stuff like this:

if (condition) {
    let a = 1;
    ...
    let a = 2;
}

Also note that case clauses inside switch blocks don't create their own block scopes, so you can't redeclare the same local variable across multiple cases without using {} to create a block each.

As for the import, you are probably getting this error because TypeScript doesn't recognize your files as actual modules, and seemingly model-level definitions end up being global definitions for it.

Try importing an external module the standard ES6 way, which contains no explicit assignment, and should make TypeScript recognize your files correctly as modules:

import * as co from "./co"

This will still result in a compile error if you have something named co already, as expected. For example, this is going to be an error:

import * as co from "./co"; // Error: import definition conflicts with local definition
let co = 1;

If you are getting an error "cannot find module co"...

TypeScript is running full type-checking against modules, so if you don't have TS definitions for the module you are trying to import (e.g. because it's a JS module without definition files), you can declare your module in a .d.ts definition file that doesn't contain module-level exports:

declare module "co" {
    declare var co: any;
    export = co;
}

• Visit phpmyadmin
• Select your database and click on structure
• In front of your table, you can see Empty, click on it to clear all the entries from the selected table.

Or you can do the same using sql query:

Click on SQL present along side Structure

TRUNCATE tablename; //offers better performance, but used only when all entries need to be cleared
or
DELETE FROM tablename; //returns the number of rows deleted

Refer to DELETE and TRUNCATE for detailed documentaion

Very often you have no option to setup the sending server so what I did I changed the XMLHttpRequest.open call in my javascript to a local get-file.php file where I have the following code in it:

<?php_x000D_
  $file = file($_GET['url']);_x000D_
  echo implode('', $file);_x000D_
?>

javascript is doing this:

var xhttp = new XMLHttpRequest();_x000D_
xhttp.onreadystatechange = function() {_x000D_
  if (this.readyState == 4 && this.status == 200) {_x000D_
    // File content is now in the this.responseText_x000D_
  }_x000D_
};_x000D_
xhttp.open("GET", "get-file.php?url=http://site/file", true);_x000D_
xhttp.send();

In my case this solved the restriction/situation just perfectly. No need to hack Firefox or servers. Just load your javascript/html file with that small php file into the server and you're done.

Your second delegate is not a rewrite of the first in anonymous delegate (rather than lambda) format. Look at your conditions.

First:

x.ID == packageId || x.Parent.ID == packageId || x.Parent.Parent.ID == packageId

Second:

(x.ID == packageId) || (x.Parent != null && x.Parent.ID == packageId) || 
(x.Parent != null && x.Parent.Parent != null && x.Parent.Parent.ID == packageId)

The call to the lambda would throw an exception for any x where the ID doesn't match and either the parent is null or doesn't match and the grandparent is null. Copy the null checks into the lambda and it should work correctly.

Edit after Comment to Question

If your original object is not a List<T>, then we have no way of knowing what the return type of FindAll() is, and whether or not this implements the IQueryable interface. If it does, then that likely explains the discrepancy. Because lambdas can be converted at compile time into an Expression<Func<T>> but anonymous delegates cannot, then you may be using the implementation of IQueryable when using the lambda version but LINQ-to-Objects when using the anonymous delegate version.

This would also explain why your lambda is not causing a NullReferenceException. If you were to pass that lambda expression to something that implements IEnumerable<T> but not IQueryable<T>, runtime evaluation of the lambda (which is no different from other methods, anonymous or not) would throw a NullReferenceException the first time it encountered an object where ID was not equal to the target and the parent or grandparent was null.

Added 3/16/2011 8:29AM EDT

Consider the following simple example:

IQueryable<MyObject> source = ...; // some object that implements IQueryable<MyObject>

var anonymousMethod =  source.Where(delegate(MyObject o) { return o.Name == "Adam"; });    
var expressionLambda = source.Where(o => o.Name == "Adam");

These two methods produce entirely different results.

The first query is the simple version. The anonymous method results in a delegate that's then passed to the IEnumerable<MyObject>.Where extension method, where the entire contents of source will be checked (manually in memory using ordinary compiled code) against your delegate. In other words, if you're familiar with iterator blocks in C#, it's something like doing this:

public IEnumerable<MyObject> MyWhere(IEnumerable<MyObject> dataSource, Func<MyObject, bool> predicate)
{
    foreach(MyObject item in dataSource)
    {
        if(predicate(item)) yield return item;
    }
}

The salient point here is that you're actually performing your filtering in memory on the client side. For example, if your source were some SQL ORM, there would be no WHERE clause in the query; the entire result set would be brought back to the client and filtered there.

The second query, which uses a lambda expression, is converted to an Expression<Func<MyObject, bool>> and uses the IQueryable<MyObject>.Where() extension method. This results in an object that is also typed as IQueryable<MyObject>. All of this works by then passing the expression to the underlying provider. This is why you aren't getting a NullReferenceException. It's entirely up to the query provider how to translate the expression (which, rather than being an actual compiled function that it can just call, is a representation of the logic of the expression using objects) into something it can use.

An easy way to see the distinction (or, at least, that there is) a distinction, would be to put a call to AsEnumerable() before your call to Where in the lambda version. This will force your code to use LINQ-to-Objects (meaning it operates on IEnumerable<T> like the anonymous delegate version, not IQueryable<T> like the lambda version currently does), and you'll get the exceptions as expected.

TL;DR Version

The long and the short of it is that your lambda expression is being translated into some kind of query against your data source, whereas the anonymous method version is evaluating the entire data source in memory. Whatever is doing the translating of your lambda into a query is not representing the logic that you're expecting, which is why it isn't producing the results you're expecting.

DataNucleus JPA that I use also has a way of doing this in its docs. No need for Spring, or ugly implementation of PersistenceUnitInfo.

Simply do as follows

import org.datanucleus.metadata.PersistenceUnitMetaData;
import org.datanucleus.api.jpa.JPAEntityManagerFactory;

PersistenceUnitMetaData pumd = new PersistenceUnitMetaData("dynamic-unit", "RESOURCE_LOCAL", null);
pumd.addClassName("mydomain.test.A");
pumd.setExcludeUnlistedClasses();
pumd.addProperty("javax.persistence.jdbc.url", "jdbc:h2:mem:nucleus");
pumd.addProperty("javax.persistence.jdbc.user", "sa");
pumd.addProperty("javax.persistence.jdbc.password", "");
pumd.addProperty("datanucleus.schema.autoCreateAll", "true");

EntityManagerFactory emf = new JPAEntityManagerFactory(pumd, null);

To debug optimized code, learn assembly/machine language.

Use the GDB TUI mode. My copy of GDB enables it when I type the minus and Enter. Then type C-x 2 (that is hold down Control and press X, release both and then press 2). That will put it into split source and disassembly display. Then use stepi and nexti to move one machine instruction at a time. Use C-x o to switch between the TUI windows.

Download a PDF about your CPU's machine language and the function calling conventions. You will quickly learn to recognize what is being done with function arguments and return values.

You can display the value of a register by using a GDB command like p $eax

@John, Earlz and Nathan. The way I learned it at uni is: functions return values, methods don't. In some languages the syntax is/was actually different. Example (no specific language):

Method SetY(int y) ...
Function CalculateY(int x) As Integer ...

Most languages now use the same syntax for both versions, using void as a return type to say there actually isn't a return type. I assume it's because the syntax is more consistent and easier to change from method to function, and vice versa.

Though all above answers are correct, below one is handy to use if you need count of last many commits

below one is to get count of last 5 commits

git diff $(git log -5 --pretty=format:"%h" | tail -1) --shortstat

to get count of last 10 commits

git diff $(git log -10 --pretty=format:"%h" | tail -1) --shortstat

generic - change N with count of last many commits you need

git diff $(git log -N --pretty=format:"%h" | tail -1) --shortstat

to get count of all commits since start

git diff $(git log --pretty=format:"%h" | tail -1) --shortstat

In your controller, render the new action from your create action if validation fails, with an instance variable, @car populated from the user input (i.e., the params hash). Then, in your view, add a logic check (either an if block around the form or a ternary on the helpers, your choice) that automatically sets the value of the form fields to the params values passed in to @car if car exists. That way, the form will be blank on first visit and in theory only be populated on re-render in the case of error. In any case, they will not be populated unless @car is set.

As said earlier "Representing money as a double or float will probably look good at first as the software rounds off the tiny errors, but as you perform more additions, subtractions, multiplications and divisions on inexact numbers, you’ll lose more and more precision as the errors add up. This makes floats and doubles inadequate for dealing with money, where perfect accuracy for multiples of base 10 powers is required."

Finally Java has a standard way to work with Currency And Money!

JSR 354: Money and Currency API

JSR 354 provides an API for representing, transporting, and performing comprehensive calculations with Money and Currency. You can download it from this link:

JSR 354: Money and Currency API Download

The specification consists of the following things:

1. An API for handling e. g. monetary amounts and currencies
2. APIs to support interchangeable implementations
3. Factories for creating instances of the implementation classes
4. Functionality for calculations, conversion and formatting of monetary amounts
5. Java API for working with Money and Currencies, which is planned to be included in Java 9.
6. All specification classes and interfaces are located in the javax.money.* package.

Sample Examples of JSR 354: Money and Currency API:

An example of creating a MonetaryAmount and printing it to the console looks like this:

MonetaryAmountFactory<?> amountFactory = Monetary.getDefaultAmountFactory();
MonetaryAmount monetaryAmount = amountFactory.setCurrency(Monetary.getCurrency("EUR")).setNumber(12345.67).create();
MonetaryAmountFormat format = MonetaryFormats.getAmountFormat(Locale.getDefault());
System.out.println(format.format(monetaryAmount));

When using the reference implementation API, the necessary code is much simpler:

MonetaryAmount monetaryAmount = Money.of(12345.67, "EUR");
MonetaryAmountFormat format = MonetaryFormats.getAmountFormat(Locale.getDefault());
System.out.println(format.format(monetaryAmount));

The API also supports calculations with MonetaryAmounts:

MonetaryAmount monetaryAmount = Money.of(12345.67, "EUR");
MonetaryAmount otherMonetaryAmount = monetaryAmount.divide(2).add(Money.of(5, "EUR"));

CurrencyUnit and MonetaryAmount

// getting CurrencyUnits by locale
CurrencyUnit yen = MonetaryCurrencies.getCurrency(Locale.JAPAN);
CurrencyUnit canadianDollar = MonetaryCurrencies.getCurrency(Locale.CANADA);

MonetaryAmount has various methods that allow accessing the assigned currency, the numeric amount, its precision and more:

MonetaryAmount monetaryAmount = Money.of(123.45, euro);
CurrencyUnit currency = monetaryAmount.getCurrency();
NumberValue numberValue = monetaryAmount.getNumber();

int intValue = numberValue.intValue(); // 123
double doubleValue = numberValue.doubleValue(); // 123.45
long fractionDenominator = numberValue.getAmountFractionDenominator(); // 100
long fractionNumerator = numberValue.getAmountFractionNumerator(); // 45
int precision = numberValue.getPrecision(); // 5

// NumberValue extends java.lang.Number.
// So we assign numberValue to a variable of type Number
Number number = numberValue;

MonetaryAmounts can be rounded using a rounding operator:

CurrencyUnit usd = MonetaryCurrencies.getCurrency("USD");
MonetaryAmount dollars = Money.of(12.34567, usd);
MonetaryOperator roundingOperator = MonetaryRoundings.getRounding(usd);
MonetaryAmount roundedDollars = dollars.with(roundingOperator); // USD 12.35

When working with collections of MonetaryAmounts, some nice utility methods for filtering, sorting and grouping are available.

List<MonetaryAmount> amounts = new ArrayList<>();
amounts.add(Money.of(2, "EUR"));
amounts.add(Money.of(42, "USD"));
amounts.add(Money.of(7, "USD"));
amounts.add(Money.of(13.37, "JPY"));
amounts.add(Money.of(18, "USD"));

Custom MonetaryAmount operations

// A monetary operator that returns 10% of the input MonetaryAmount
// Implemented using Java 8 Lambdas
MonetaryOperator tenPercentOperator = (MonetaryAmount amount) -> {
    BigDecimal baseAmount = amount.getNumber().numberValue(BigDecimal.class);
    BigDecimal tenPercent = baseAmount.multiply(new BigDecimal("0.1"));
    return Money.of(tenPercent, amount.getCurrency());
};

MonetaryAmount dollars = Money.of(12.34567, "USD");

// apply tenPercentOperator to MonetaryAmount
MonetaryAmount tenPercentDollars = dollars.with(tenPercentOperator); // USD 1.234567

By.cssSelector(".ban") or By.cssSelector(".hot") or By.cssSelector(".ban.hot") should all select it unless there is another element that has those classes.

In CSS, .name means find an element that has a class with name. .foo.bar.baz means to find an element that has all of those classes (in the same element).

However, each of those selectors will select only the first element that matches it on the page. If you need something more specific, please post the HTML of the other elements that have those classes.

I had a similar issue. You won't be able to ping the VM's from external devices if using NAT setting from within VMware's networking options. I switched to bridged connection so that the guest virtual machine will get it's own IP address and and then I added a second adapter set to NAT for the guest to get to the Internet.

I recommend use /(?=.*...)/g

Example

const text1 = 'I am using regex';
/(?=.*regex)/g.test(text1) // true

const text2 = 'regex is awesome';
/(?=.*regex)/g.test(text2) // true

const text3 = 'regex is util';
/(?=.*util)(?=.*regex)/g.test(text3) // true

const text4 = 'util is necessary';
/(?=.*util)(?=.*regex)/g.test(text4) // false because need regex in text

Use regex101 to test

It looks like the cause of the errors are:

1. You're currently loading the source file in the src directory instead of the built file in the dist directory (you can see what the intended distributed file is here). This means that you're using the native source code in an unaltered/unbundled state, leading to the following error: Uncaught SyntaxError: Cannot use import statement outside a module. This should be fixed by using the bundled version since the package is using rollup to create a bundle.

2. The reason you're getting the Uncaught ReferenceError: ms is not defined error is because modules are scoped, and since you're loading the library using native modules, ms is not in the global scope and is therefore not accessible in the following script tag.

It looks like you should be able to load the dist version of this file to have ms defined on the window. Check out this example from the library author to see an example of how this can be done.

Use DateFormat#parse(String):

Date date = dateFormat.parse("2013-10-22");

This question is old but I struggled for a long time trying to get an answer to this problem that would work for my needs and did not easily find it. I believe my following solution is much better than the currently accepted one, perhaps because angular has added functionality since this question was originally posed.

Short answer, using the Module.value method allows you to pass data into a controller constructor.

See my plunker here

I create a model object, then associate it with the module's controller, referencing it with the name 'model'

HTML / JS

  <html>
  <head>
    <script>
      var model = {"id": 1, "name":"foo"};

      $(document).ready(function(){
        var module = angular.module('myApp', []);
        module.value('model', model);
        module.controller('MyController', ['model', MyController]);
        angular.bootstrap(document, ['myApp']);
      });

      function confirmModelEdited() {
        alert("model name: " + model.name + "\nmodel id: " + model.id);
      }
    </script>

  </head>
  <body >
      <div ng-controller="MyController as controller">
        id: {{controller.model.id}} <br>
        name: <input ng-model="controller.model.name"/>{{controller.model.name}}
        <br><button ng-click="controller.incrementId()">increment ID</button>
        <br><button onclick="confirmModelEdited()">confirm model was edited</button>
    </div>
  </body>

</html>

The constructor in my controller then accepts a parameter with that same identifier 'model' which it can then access.

Controller

function MyController (model) {
  this.model = model;
}

MyController.prototype.incrementId = function() {
  this.model.id = this.model.id + 1;
}

Notes:

I'm using manual initialization of bootstrapping, which allows me to initialize my model before sending it over to angular. This plays much more nicely with existing code, as you can wait to set up your relevant data and only compile the angular subset of your app on demand when you want to.

In the plunker I've added a button to alert the values of the model object that was initially defined in javascript and passed to angular, just to confirm that angular is truly referencing the model object, rather than copying it and working with a copy.

On this line:

module.controller('MyController', ['model', MyController]);

I'm passing the MyController object into the Module.controller function, rather than declaring as a function inline. I think this allows us to far more clearly define our controller object, but Angular documentation tends to do it inline so I thought it bears clarification.

I'm using the "controller as" syntax and assigning values to the "this" property of MyController, rather than using the "$scope" variable. I believe this would work fine using $scope just as well, the controller assignment would then look something like this:

module.controller('MyController', ['$scope', 'model', MyController]);

and the controller constructor would have a signature like this:

function MyController ($scope, model) {

If for whatever reason you wanted to, you could also attach this model as a value of a second module, which you then attach as a dependency to your primary module.

I believe his solution is much better than the currently accepted one because

1. The model passed to the controller is actually a javascript object, not a string that gets evaluated. It is a true reference to the object and changes to it affect other references to this model object.
2. Angular says that the accepted answer's use of ng-init is a misuse, which this solution doesn't do.

The way Angular seems to work in most all other examples I've seen has the controller defining the data of the model, which never made sense to me, there is no separation between the model and the controller, that doesn't really seem like MVC to me. This solution allows you to really have a completely separate model object which you pass into the controller. Also of note, if you use the ng-include directive you can put all your angular html in a separate file, fully separating your model view and controller into separate modular pieces.

You should be able to specify the number of digits you want to round to using Math.Round(YourNumber, 2)

When i need to copy data from filtered table i use range.SpecialCells(xlCellTypeVisible).copy. Where the range is range of all data (without a filter).

Example:

Sub copy()
     'source worksheet
     dim ws as Worksheet
     set ws = Application.Worksheets("Data")' set you source worksheet here
     dim data_end_row_number as Integer
     data_end_row_number = ws.Range("B3").End(XlDown).Row.Number
    'enable filter
    ws.Range("B2:F2").AutoFilter Field:=2, Criteria1:="hockey", VisibleDropDown:=True
    ws.Range("B3:F" & data_end_row_number).SpecialCells(xlCellTypeVisible).Copy
    Application.Worksheets("Hoky").Range("B3").Paste
    'You have to add headers to Hoky worksheet
end sub

You can retrieve the format strings from the CultureInfo DateTimeFormat property, which is a DateTimeFormatInfo instance. This in turn has properties like ShortDatePattern and ShortTimePattern, containing the format strings:

CultureInfo us = new CultureInfo("en-US");
string shortUsDateFormatString = us.DateTimeFormat.ShortDatePattern;
string shortUsTimeFormatString = us.DateTimeFormat.ShortTimePattern;

CultureInfo uk = new CultureInfo("en-GB");
string shortUkDateFormatString = uk.DateTimeFormat.ShortDatePattern;
string shortUkTimeFormatString = uk.DateTimeFormat.ShortTimePattern;

If you simply want to format the date/time using the CultureInfo, pass it in as your IFormatter when converting the DateTime to a string, using the ToString method:

string us = myDate.ToString(new CultureInfo("en-US"));
string uk = myDate.ToString(new CultureInfo("en-GB"));

(Update: If I could delete this answer I would, although since it's accepted, I can't. I'm updating the description to provide better guidance and discourage folks from using the poor practice I outlined in the original answer).

You can specify these parameters via context or environment parameters, such as in context.xml. See the sections titled "Context Parameters" and "Environment Entries" on this page:

http://tomcat.apache.org/tomcat-5.5-doc/config/context.html

As @netjeff points out, these values will be available via the Context.lookup(String) method and not as System parameters.

Another way to do specify these values is to define variables inside of the web.xml file of the web application you're deploying (see below). As @Roberto Lo Giacco points out, this is generally considered a poor practice since a deployed artifact should not be environment specific. However, below is the configuration snippet if you really want to do this:

<env-entry>
    <env-entry-name>SMTP_PASSWORD</env-entry-name>
    <env-entry-type>java.lang.String</env-entry-type>
    <env-entry-value>abc123ftw</env-entry-value>
</env-entry>

An example with variable (ES6):

const item = document.querySelector([data-itemid="${id}"]);

You maybe wanted to do the following:

foreach($user->data as $mydata)

    {
         echo $mydata->name . "\n";
         foreach($mydata->values as $values)
         {
              echo $values->value . "\n";
         }
    }        

According to your question...

How to pass parameters to Thread.ThreadStart() method in C#?

...and the error you encountered, you would have to correct your code from

Thread thread = new Thread(new ThreadStart(download(filename));

to

Thread thread = new Thread(new ThreadStart(download));
thread.Start(filename);

However, the question is more complex as it seems at first.

The Thread class currently (4.7.2) provides several constructors and a Start method with overloads.

These relevant constructors for this question are:

public Thread(ThreadStart start);

and

public Thread(ParameterizedThreadStart start);

which either take a ThreadStart delegate or a ParameterizedThreadStart delegate.

The corresponding delegates look like this:

public delegate void ThreadStart();
public delegate void ParameterizedThreadStart(object obj);

So as can be seen, the correct constructor to use seems to be the one taking a ParameterizedThreadStart delegate so that some method conform to the specified signature of the delegate can be started by the thread.

A simple example for instanciating the Thread class would be

Thread thread = new Thread(new ParameterizedThreadStart(Work));

or just

Thread thread = new Thread(Work);

The signature of the corresponding method (called Work in this example) looks like this:

private void Work(object data)
{
   ...
}

What is left is to start the thread. This is done by using either

public void Start();

or

public void Start(object parameter);

While Start() would start the thread and pass null as data to the method, Start(...) can be used to pass anything into the Work method of the thread.

There is however one big problem with this approach: Everything passed into the Work method is cast into an object. That means within the Work method it has to be cast to the original type again like in the following example:

public static void Main(string[] args)
{
    Thread thread = new Thread(Work);

    thread.Start("I've got some text");
    Console.ReadLine();
}

private static void Work(object data)
{
    string message = (string)data; // Wow, this is ugly

    Console.WriteLine($"I, the thread write: {message}");
}

Casting is something you typically do not want to do.

What if someone passes something else which is not a string? As this seems not possible at first (because It is my method, I know what I do or The method is private, how should someone ever be able to pass anything to it?) you may possibly end up with exactly that case for various reasons. As some cases may not be a problem, others are. In such cases you will probably end up with an InvalidCastException which you probably will not notice because it simply terminates the thread.

As a solution you would expect to get a generic ParameterizedThreadStart delegate like ParameterizedThreadStart<T> where T would be the type of data you want to pass into the Work method. Unfortunately something like this does not exist (yet?).

There is however a suggested solution to this issue. It involves creating a class which contains both, the data to be passed to the thread as well as the method that represents the worker method like this:

public class ThreadWithState
{
    private string message;

    public ThreadWithState(string message)
    {
        this.message = message;
    }

    public void Work()
    {
        Console.WriteLine($"I, the thread write: {this.message}");
    }
}

With this approach you would start the thread like this:

ThreadWithState tws = new ThreadWithState("I've got some text");
Thread thread = new Thread(tws.Work);

thread.Start();

So in this way you simply avoid casting around and have a typesafe way of providing data to a thread ;-)

I faced the same problem due to illegal spaces in my entire code.

I fixed it by selecting one of these spaces and use find and replace to replace all matches with regular spaces.

This worked for me :

I made a custom image component which takes in a boolean to check if the image is from web or is being passed from a local folder.

// In index.ios.js after importing the component
<CustomImage fromWeb={false} imageName={require('./images/logo.png')}/>

// In CustomImage.js which is my image component
<Image style={styles.image} source={this.props.imageName} />

If you see the code, instead of using one of these:

// NOTE: Neither of these will work
source={require('../images/'+imageName)} 
var imageName = require('../images/'+imageName)

I'm just sending the entire require('./images/logo.png') as a prop. It works!

The best methods are already given but why not look at a couple of other methods for fun? Warning: these are more expensive methods but do serve in other circumstances.

The expensive regex method and the css attribute selector with starts with ^ operator

Option Explicit

Public Sub test()

    Debug.Print StartWithSubString("ab", "abc,d")

End Sub

Regex:

Public Function StartWithSubString(ByVal substring As String, ByVal testString As String) As Boolean
    'required reference Microsoft VBScript Regular Expressions
    Dim re As VBScript_RegExp_55.RegExp
    Set re = New VBScript_RegExp_55.RegExp

    re.Pattern = "^" & substring

    StartWithSubString = re.test(testString)

End Function

Css attribute selector with starts with operator

Public Function StartWithSubString(ByVal substring As String, ByVal testString As String) As Boolean
    'required reference Microsoft HTML Object Library
    Dim html As MSHTML.HTMLDocument
    Set html = New MSHTML.HTMLDocument

    html.body.innerHTML = "<div test=""" & testString & """></div>"

    StartWithSubString = html.querySelectorAll("[test^=" & substring & "]").Length > 0

End Function

If you are using Netbeans to develop, use jLabel and change it's icon property.

not really eleganter, but a bit shorter would be

function to_tuple(x):
   y = 60*60*1000
   h = x/y
   m = (x-(h*y))/(y/60)
   s = (x-(h*y)-(m*(y/60)))/1000
   mi = x-(h*y)-(m*(y/60))-(s*1000)

   return (h,m,s,mi)

Make sure those two types are nullable DateTime

var lastPostDate = reader[3] == DBNull.Value ?
                                        null : 
                                   (DateTime?) Convert.ToDateTime(reader[3]);

• Usage of DateTime? instead of Nullable<DateTime> is a time saver...
• Use better indent of the ? expression like I did.

I have found this excellent explanations in Eric Lippert blog:

The specification for the ?: operator states the following:

The second and third operands of the ?: operator control the type of the conditional expression. Let X and Y be the types of the second and third operands. Then,

• If X and Y are the same type, then this is the type of the conditional expression.

• Otherwise, if an implicit conversion exists from X to Y, but not from Y to X, then Y is the type of the conditional expression.

• Otherwise, if an implicit conversion exists from Y to X, but not from X to Y, then X is the type of the conditional expression.

• Otherwise, no expression type can be determined, and a compile-time error occurs.

The compiler doesn't check what is the type that can "hold" those two types.

In this case:

• null and DateTime aren't the same type.
• null doesn't have an implicit conversion to DateTime
• DateTime doesn't have an implicit conversion to null

So we end up with a compile-time error.

I made a FIDDLE for you. I am storing a stack string and then output it, if the property is of primitive type:

function iterate(obj, stack) {
        for (var property in obj) {
            if (obj.hasOwnProperty(property)) {
                if (typeof obj[property] == "object") {
                    iterate(obj[property], stack + '.' + property);
                } else {
                    console.log(property + "   " + obj[property]);
                    $('#output').append($("<div/>").text(stack + '.' + property))
                }
            }
        }
    }

iterate(object, '')

UPDATE (17/01/2019) - <There used to be a different implementation, but it didn't work. See this answer for a prettier solution :)>

1. What is the difference between Git and GitHub?

   Linus Torvalds would kill you for this. Git is the name of the version manager program he wrote. GitHub is a website on which there are source code repositories manageable by Git. Thus, GitHub is completely unrelated to the original Git tool.

2. Is git saving every repository locally (in the user's machine) and in GitHub?

   If you commit changes, it stores locally. Then, if you push the commits, it also sotres them remotely.

3. Can you use Git without GitHub? If yes, what would be the benefit for using GitHub?

   You can, but I'm sure you don't want to manually set up a git server for yourself. Benefits of GitHub? Well, easy to use, lot of people know it so others may find your code and follow/fork it to make improvements as well.

4. How does Git compare to a backup system such as Time Machine?

   Git is specifically designed and optimized for source code.

5. Is this a manual process, in other words if you don't commit you wont have a new version of the changes made?

   Exactly.

6. If are not collaborating and you are already using a backup system why would you use Git?

   See #4.

Found this class recently, it works like a dream!

class Encryption {
    var $skey = "yourSecretKey"; // you can change it

    public  function safe_b64encode($string) {
        $data = base64_encode($string);
        $data = str_replace(array('+','/','='),array('-','_',''),$data);
        return $data;
    }

    public function safe_b64decode($string) {
        $data = str_replace(array('-','_'),array('+','/'),$string);
        $mod4 = strlen($data) % 4;
        if ($mod4) {
            $data .= substr('====', $mod4);
        }
        return base64_decode($data);
    }

    public  function encode($value){ 
        if(!$value){return false;}
        $text = $value;
        $iv_size = mcrypt_get_iv_size(MCRYPT_RIJNDAEL_256, MCRYPT_MODE_ECB);
        $iv = mcrypt_create_iv($iv_size, MCRYPT_RAND);
        $crypttext = mcrypt_encrypt(MCRYPT_RIJNDAEL_256, $this->skey, $text, MCRYPT_MODE_ECB, $iv);
        return trim($this->safe_b64encode($crypttext)); 
    }

    public function decode($value){
        if(!$value){return false;}
        $crypttext = $this->safe_b64decode($value); 
        $iv_size = mcrypt_get_iv_size(MCRYPT_RIJNDAEL_256, MCRYPT_MODE_ECB);
        $iv = mcrypt_create_iv($iv_size, MCRYPT_RAND);
        $decrypttext = mcrypt_decrypt(MCRYPT_RIJNDAEL_256, $this->skey, $crypttext, MCRYPT_MODE_ECB, $iv);
        return trim($decrypttext);
    }
}

And to call it:

$str = "My secret String";

$converter = new Encryption;
$encoded = $converter->encode($str );
$decoded = $converter->decode($encoded);    

echo "$encoded<p>$decoded";

You can do it server-side with nodejs.

Check out the popular Nodemailer package. There are plenty of transports and plugins for integrating with services like AWS SES and SendGrid!

The following example uses SES transport (Amazon SES):

let nodemailer = require("nodemailer");
let aws = require("aws-sdk");
let transporter = nodemailer.createTransport({
  SES: new aws.SES({ apiVersion: "2010-12-01" })
});

the return statement exits from the current function and exit() exits from the program

they are the same when used in main() function

also return is a statement while exit() is a function which requires stdlb.h header file

The SQL Server Maximums are disclosed http://msdn.microsoft.com/en-us/library/ms143432.aspx (this is the 2008 version)

A SQL Query can be a varchar(max) but is shown as limited to 65,536 * Network Packet size, but even then what is most likely to trip you up is the 2100 parameters per query. If SQL chooses to parameterize the literal values in the in clause, I would think you would hit that limit first, but I havn't tested it.

Edit : Test it, even under forced parameteriztion it survived - I knocked up a quick test and had it executing with 30k items within the In clause. (SQL Server 2005)

At 100k items, it took some time then dropped with:

Msg 8623, Level 16, State 1, Line 1 The query processor ran out of internal resources and could not produce a query plan. This is a rare event and only expected for extremely complex queries or queries that reference a very large number of tables or partitions. Please simplify the query. If you believe you have received this message in error, contact Customer Support Services for more information.

So 30k is possible, but just because you can do it - does not mean you should :)

Edit : Continued due to additional question.

50k worked, but 60k dropped out, so somewhere in there on my test rig btw.

In terms of how to do that join of the values without using a large in clause, personally I would create a temp table, insert the values into that temp table, index it and then use it in a join, giving it the best opportunities to optimse the joins. (Generating the index on the temp table will create stats for it, which will help the optimiser as a general rule, although 1000 GUIDs will not exactly find stats too useful.)

You can use socket.settimeout() which accepts a integer argument representing number of seconds. For example, socket.settimeout(1) will set the timeout to 1 second

As "there are tens of thousands of cells in the page" binding the click-event to every single cell will cause a terrible performance problem. There's a better way to do this, that is binding a click event to the body & then finding out if the cell element was the target of the click. Like this:

$('body').click(function(e){
       var Elem = e.target;
       if (Elem.nodeName=='td'){
           //.... your business goes here....
           // remember to replace $(this) with $(Elem)
       }
})

This method will not only do your task with native "td" tag but also with later appended "td". I think you'll be interested in this article about event binding & delegate

Or you can simply use the ".on()" method of jQuery with the same effect:

$('body').on('click', 'td', function(){
        ...
});

Here is a solution to prevent session shearing between browser tabs for a java application. This will work for IE (JSP/Servlet)

1. In your first JSP page, onload event call a servlet (ajex call) to setup a "window.title" and event tracker in the session(just a integer variable to be set as 0 for first time)
2. Make sure none of the other pages set a window.title
3. All pages (including the first page) add a java script to check the window title once the page load is complete. if the title is not found then close the current page/tab(make sure to undo the "window.unload" function when this occurs)
4. Set page window.onunload java script event(for all pages) to capture the page refresh event, if a page has been refreshed call the servlet to reset the event tracker.

1)first page JS

BODY onload="javascript:initPageLoad()"

function initPageLoad() {
    var xmlhttp;

    if (window.XMLHttpRequest) {
        // code for IE7+, Firefox, Chrome, Opera, Safari
        xmlhttp = new XMLHttpRequest();
    } else {
        // code for IE6, IE5
        xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
    }

    xmlhttp.onreadystatechange = function() {
        if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {                           var serverResponse = xmlhttp.responseText;
            top.document.title=serverResponse;
        }
    };
                xmlhttp.open("GET", 'data.do', true);
    xmlhttp.send();

}

2)common JS for all pages

window.onunload = function() {
    var xmlhttp;
    if (window.XMLHttpRequest) {
        // code for IE7+, Firefox, Chrome, Opera, Safari
        xmlhttp = new XMLHttpRequest();
    } else {
        // code for IE6, IE5
        xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
    }
    xmlhttp.onreadystatechange = function() {
        if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {             
            var serverResponse = xmlhttp.responseText;              
        }
    };

    xmlhttp.open("GET", 'data.do?reset=true', true);
    xmlhttp.send();
}

var readyStateCheckInterval = setInterval(function() {
if (document.readyState === "complete") {
    init();
    clearInterval(readyStateCheckInterval);
}}, 10);
function init(){ 
  if(document.title==""){   
  window.onunload=function() {};
  window.open('', '_self', ''); window.close();
  }
 }

3)web.xml - servlet mapping

<servlet-mapping>
<servlet-name>myAction</servlet-name>
<url-pattern>/data.do</url-pattern>     
</servlet-mapping>  
<servlet>
<servlet-name>myAction</servlet-name>
<servlet-class>xx.xxx.MyAction</servlet-class>
</servlet>

4)servlet code

public class MyAction extends HttpServlet {
 public void doGet(HttpServletRequest request, HttpServletResponse response)
        throws IOException {
    Integer sessionCount = (Integer) request.getSession().getAttribute(
            "sessionCount");
    PrintWriter out = response.getWriter();
    Boolean reset = Boolean.valueOf(request.getParameter("reset"));
    if (reset)
        sessionCount = new Integer(0);
    else {
        if (sessionCount == null || sessionCount == 0) {
            out.println("hello Title");
            sessionCount = new Integer(0);
        }
                          sessionCount++;
    }
    request.getSession().setAttribute("sessionCount", sessionCount);
    // Set standard HTTP/1.1 no-cache headers.
    response.setHeader("Cache-Control", "private, no-store, no-cache, must-                      revalidate");
    // Set standard HTTP/1.0 no-cache header.
    response.setHeader("Pragma", "no-cache");
} 
  }

The technique that the W3C has recommended for do this is called "embedding" and is well described by the three articles here: Embedding Fonts. In my limited experiments, I have found this process error-prone and have had limited success in making it function in a multi-browser environment.

1. Search "sqlLocalDb" from start menu,
2. Click on the run command,
3. Go back to VS 2015 tools/connect to database,
4. select MSSQL server,
5. enter (localdb)\MSSQLLocalDB as server name

Select your database and ready to go.

If you need an os independent method, works across Windows and Linux. Use python

$ python -c 'import multiprocessing as m; print m.cpu_count()'

Not yet mentioned here, another choice is environment aligned, again from package amsmath:

\documentclass{article}
\usepackage{amsmath}

\begin{document}

\begin{equation}
  \begin{aligned}
    A & = B + C\\
      & = D + E + F\\
      & = G
  \end{aligned}
\end{equation}

\end{document}

This outputs:

Here is a very quick and simple solution:

self.navigationController.hidesBarsOnTap = YES;

This will work on single tap instead of double tap. Also it will change the behavior for the navigation controller even after pushing or popping the current view controller.

You can always modify this behavior in your controller within the viewWillAppear: and viewWillDisappear: actions if you would like to set the behavior only for a single view controller.

Here is the documentation:

Default the contents to display:none and then have an event handler that sets it to display:block or similar after it's fully loaded. Then have a div that's set to display:block with "Loading" in it, and set it to display:none in the same event handler as before.

Another approach if you want to use a varying portion of the dataset instead of a single value is to use rollapply(data, width, FUN, ...). Using a vector of widths allows you to apply a function on a varying window of the dataset. I've used this to build an adaptive filtering routine, though it isn't very efficient.

ES6 sample

const validateEmail=(email)=> /^(([^<>()\[\]\\.,;:\s@"]+(\.[^<>()\[\]\\.,;:\s@"]+)*)|(".+"))@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/.test(email);

try the command

> forever logs

or

> sudo forever logs

you will get the log file's location

Yes, you can.

The main method in Java is no extra-terrestrial method. Apart from the fact that main() is just like any other method & can be overloaded in a similar manner, JVM always looks for the method signature to launch the program.

• The normal main method acts as an entry point for the JVM to start the execution of program.

• We can overload the main method in Java. But the program doesn’t
  execute the overloaded main method when we run your program, we need to call the overloaded main method from the actual main method only.

  // A Java program with overloaded main()
  import java.io.*;     
  public class Test {         
    // Normal main()
    public static void main(String[] args) {
      System.out.println("Hi Geek (from main)");
      Test.main("Geek");
    }     
    // Overloaded main methods
    public static void main(String arg1) {
      System.out.println("Hi, " + arg1);
      Test.main("Dear Geek","My Geek");
    }
    public static void main(String arg1, String arg2) {
      System.out.println("Hi, " + arg1 + ", " + arg2);
    }
  }

Adding to the other great answers, we can use the Python logging library's debug(), info(), warning(), error(), and critical() methods. Quoting from the docs for Python 3.7.4,

There are three keyword arguments in kwargs which are inspected: exc_info which, if it does not evaluate as false, causes exception information to be added to the logging message.

What this means is, you can use the Python logging library to output a debug(), or other type of message, and the logging library will include the stack trace in its output. With this in mind, we can do the following:

import logging

logger = logging.getLogger()
logger.setLevel(logging.DEBUG)

def f():
    a = { 'foo': None }
    # the following line will raise KeyError
    b = a['bar']

def g():
    f()

try:
    g()
except Exception as e:
    logger.error(str(e), exc_info=True)

And it will output:

'bar'
Traceback (most recent call last):
  File "<ipython-input-2-8ae09e08766b>", line 18, in <module>
    g()
  File "<ipython-input-2-8ae09e08766b>", line 14, in g
    f()
  File "<ipython-input-2-8ae09e08766b>", line 10, in f
    b = a['bar']
KeyError: 'bar'

Recently I had a similar problem, the problem was I was using background-color, use background: {anyColor}

example:

tr::hover td {background: red;}

This works like charm!

I tried some of the suggestions here and I would like to present mine (which is a bit different) - I hope it will help someone. I wanted to show the popup on first click and hide it on second click (of course with updating the data each time). I used an extra variable visable to know whether the popover is visable or not. Here is my code: HTML:

<button type="button" id="votingTableButton" class="btn btn-info btn-xs" data-container="body" data-toggle="popover" data-placement="left" >Last Votes</button>

Javascript:

$('#votingTableButton').data("visible",false);

$('#votingTableButton').click(function() {  
if ($('#votingTableButton').data("visible")) {
    $('#votingTableButton').popover("hide");
    $('#votingTableButton').data("visible",false);          
}
else {
    $.get('votingTable.json', function(data) {
        var content = generateTableContent(data);
        $('#votingTableButton').popover('destroy');
        $('#votingTableButton').popover({title: 'Last Votes', 
                                content: content, 
                                trigger: 'manual',
                                html:true});
        $('#votingTableButton').popover("show");
        $('#votingTableButton').data("visible",true);   
    });
}   
});

Cheers!

Personally, I have create a file.sh (right 755) in the root directory, file who do this job, on order of the crontab.

Crontab code:

10 2 * * * root /root/backupautomatique.sh

File.sh code:

rm -f /home/mordb-148-251-89-66.sql.gz #(To erase the old one)

mysqldump mor | gzip > /home/mordb-148-251-89-66.sql.gz (what you have done)

scp -P2222 /home/mordb-148-251-89-66.sql.gz root@otherip:/home/mordbexternes/mordb-148-251-89-66.sql.gz

(to send a copy somewhere else if the sending server crashes, because too old, like me ;-))

You can remove them from /Library/Developer/CoreSimulator/Profiles/Runtimes (Not ~/Library!):

Has not been tested on IE, so it may look broken on IE.

For both hardware device back button and soft home (back) button e.g. " <- " this is what works for me. (*Note I have an app bar / toolbar in the activity)

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
        case android.R.id.home:
            //finish();
            onBackPressed();
            break;
    }
    return true;
}



@Override
public void onBackPressed() {
   //Execute your code here
   finish();

}

Cheers!

You can use the break keyword.

The proper function is int fileno(FILE *stream). It can be found in <stdio.h>, and is a POSIX standard but not standard C.

You cannot select on specific values (or types of values). You'd either make a reverse index (map numbers back to (lists of) keys) or you have to loop through all values every time.

If you are processing numbers in arbitrary order anyway, you may as well loop through all items:

for key, value in inputdict.items():
    # do something with value
    inputdict[key] = newvalue

otherwise I'd go with the reverse index:

from collections import defaultdict

reverse = defaultdict(list)
for key, value in inputdict.items():
    reverse[value].append(key)

Now you can look up keys by value:

for key in reverse[value]:
    inputdict[key] = newvalue

You could use assign with a dict of column names and values.

In [1069]: df.assign(**{'col_new_1': np.nan, 'col2_new_2': 'dogs', 'col3_new_3': 3})
Out[1069]:
   col_1  col_2 col2_new_2  col3_new_3  col_new_1
0      0      4       dogs           3        NaN
1      1      5       dogs           3        NaN
2      2      6       dogs           3        NaN
3      3      7       dogs           3        NaN

It is not strictly possible in default db due to the many public executes that each user gains automatically through public.

As mentioned above, a[::-1] really only creates a view, so it's a constant-time operation (and as such doesn't take longer as the array grows). If you need the array to be contiguous (for example because you're performing many vector operations with it), ascontiguousarray is about as fast as flipud/fliplr:

Code to generate the plot:

import numpy
import perfplot


perfplot.show(
    setup=lambda n: numpy.random.randint(0, 1000, n),
    kernels=[
        lambda a: a[::-1],
        lambda a: numpy.ascontiguousarray(a[::-1]),
        lambda a: numpy.fliplr([a])[0],
    ],
    labels=["a[::-1]", "ascontiguousarray(a[::-1])", "fliplr"],
    n_range=[2 ** k for k in range(25)],
    xlabel="len(a)",
)

  //create the url
  $profile_pic =  "http://graph.facebook.com/".$uid."/picture";

 //echo the image out
 echo "<img src=\"" . $profile_pic . "\" />"; 

Works fine for me

I red all the stuff above, about 40 other pages with c++ in it like this and watched the video from Stephan T. Lavavej "STL" and still wasn't sure how random numbers works in praxis so I took a full Sunday to figure out what its all about and how it works and can be used.

In my opinion STL is right about "not using srand anymore" and he explained it well in the video 2. He also recommend to use:

a) void random_device_uniform() -- for encrypted generation but slower (from my example)

b) the examples with mt19937 -- faster, ability to create seeds, not encrypted

I pulled out all claimed c++11 books I have access to and found f.e. that german Authors like Breymann (2015) still use a clone of

srand( time( 0 ) );
srand( static_cast<unsigned int>(time(nullptr))); or
srand( static_cast<unsigned int>(time(NULL))); or

just with <random> instead of <time> and <cstdlib> #includings - so be careful to learn just from one book :).

Meaning - that shouldn't be used since c++11 because:

Programs often need a source of random numbers. Prior to the new standard, both C and C++ relied on a simple C library function named rand. That function produces pseudorandom integers that are uniformly distributed in the range from 0 to a system- dependent maximum value that is at least 32767. The rand function has several problems: Many, if not most, programs need random numbers in a different range from the one produced by rand. Some applications require random floating-point numbers. Some programs need numbers that reflect a nonuniform distribution. Programmers often introduce nonrandomness when they try to transform the range, type, or distribution of the numbers generated by rand. (quote from Lippmans C++ primer fifth edition 2012)

I finally found a the best explaination out of 20 books in Bjarne Stroustrups newer ones - and he should know his stuff - in "A tour of C++ 2019", "Programming Principles and Practice Using C++ 2016" and "The C++ Programming Language 4th edition 2014" and also some examples in "Lippmans C++ primer fifth edition 2012":

And it is really simple because a random number generator consists of two parts: (1) an engine that produces a sequence of random or pseudo-random values. (2) a distribution that maps those values into a mathematical distribution in a range.

Despite the opinion of Microsofts STL guy, Bjarne Stroustrups writes:

In , the standard library provides random number engines and distributions (§24.7). By default use the default_random_engine , which is chosen for wide applicability and low cost.

The void die_roll() Example is from Bjarne Stroustrups - good idea generating engine and distribution with using (more bout that here).

To be able to make practical use of the random number generators provided by the standard library in <random> here some executable code with different examples reduced to the least necessary that hopefully safe time and money for you guys:

    #include <random>     //random engine, random distribution
    #include <iostream>   //cout
    #include <functional> //to use bind

    using namespace std;

       cout << "###";
       cout << "\n" << endl;
    }

    void uniform_default()
    {
    // uniformly distributed from 0 to 6 inclusive
        uniform_int_distribution<size_t> u (0, 6);
        default_random_engine e;  // generates unsigned random integers

    for (size_t i = 0; i < 10; ++i)
        // u uses e as a source of numbers
        // each call returns a uniformly distributed value in the specified range
        cout << u(e) << " ";
    }

    void random_device_uniform()
    {
         space();

I think that adds it all up and like I said, it took me a bunch of reading and time to destill it to that examples - if you have further stuff about number generation I am happy to hear about that via pm or in the comment section and will add it if necessary or edit this post. Bool

If you need

• O(1) insertion and removal
• O(1) indexing to interior elements
• access from a single thread only
• generic element type

then you can use this CircularArrayList for Java in this way (for example):

CircularArrayList<String> buf = new CircularArrayList<String>(4);

buf.add("A");
buf.add("B");
buf.add("C");
buf.add("D"); // ABCD

String pop = buf.remove(0); // A <- BCD
buf.add("E"); // BCDE

String interiorElement = buf.get(i);

All these methods run in O(1).

Java's interface for reading filesystem folder contents is not very performant (as you've discovered). JDK 7 fixes this with a completely new interface for this sort of thing, which should bring native level performance to these sorts of operations.

The core issue is that Java makes a native system call for every single file. On a low latency interface, this is not that big of a deal - but on a network with even moderate latency, it really adds up. If you profile your algorithm above, you'll find that the bulk of the time is spent in the pesky isDirectory() call - that's because you are incurring a round trip for every single call to isDirectory(). Most modern OSes can provide this sort of information when the list of files/folders was originally requested (as opposed to querying each individual file path for it's properties).

If you can't wait for JDK7, one strategy for addressing this latency is to go multi-threaded and use an ExecutorService with a maximum # of threads to perform your recursion. It's not great (you have to deal with locking of your output data structures), but it'll be a heck of a lot faster than doing this single threaded.

In all of your discussions about this sort of thing, I highly recommend that you compare against the best you could do using native code (or even a command line script that does roughly the same thing). Saying that it takes an hour to traverse a network structure doesn't really mean that much. Telling us that you can do it native in 7 second, but it takes an hour in Java will get people's attention.

@Golmaal really answered this, I'm just being a bit more verbose.

<style type="text/css">
    #warning-message { display: none; }
    @media only screen and (orientation:portrait){
        #wrapper { display:none; }
        #warning-message { display:block; }
    }
    @media only screen and (orientation:landscape){
        #warning-message { display:none; }
    }
</style>

....

<div id="wrapper">
    <!-- your html for your website -->
</div>
<div id="warning-message">
    this website is only viewable in landscape mode
</div>

You have no control over the user moving the orientation however you can at least message them. This example will hide the wrapper if in portrait mode and show the warning message and then hide the warning message in landscape mode and show the portrait.

I don't think this answer is any better than @Golmaal , only a compliment to it. If you like this answer, make sure to give @Golmaal the credit.

Update

I've been working with Cordova a lot recently and it turns out you CAN control it when you have access to the native features.

Another Update

So after releasing Cordova it is really terrible in the end. It is better to use something like React Native if you want JavaScript. It is really amazing and I know it isn't pure web but the pure web experience on mobile kind of failed.

Sleep causes thread to suspend itself for x milliseconds while yield suspends the thread and immediately moves it to the ready queue (the queue which the CPU uses to run threads).

@require is NOT only processed when the script is first installed! On my observations it is proccessed on the first execution time! So you can install a script via Greasemonkey's command for creating a brand-new script. The only thing you have to take care about is, that there is no page reload triggered, befor you add the @requirepart. (and save the new script...)

A while back, I wrote about this in Cross Browser Background Transparency With CSS.

Bizarrely Internet Explorer 6 will allow you to make the background transparent and keep the text on top fully opaque. For the other browsers I then suggest using a transparent PNG file.

var table = new DataTable();    
using (var da = new SqlDataAdapter("SELECT * FROM mytable", "connection string"))
{      
    da.Fill(table);
}

If you ran into this issue when using TypeScript, you may need to add skipLibCheck: true in your tsconfig.json file.

In your example, there will be no difference, since both statements appear at the end of the loop. pass is simply a placeholder, in that it does nothing (it passes execution to the next statement). continue, on the other hand, has a definite purpose: it tells the loop to continue as if it had just restarted.

for element in some_list:
    if not element:
        pass
    print element  

is very different from

for element in some_list:
    if not element:
        continue
    print element

In my experience it's best to put as much code as you can into well-named modules, and only put as much code as you need to into the actual worksheet objects.

Example: Any code that uses worksheet events like Worksheet_SelectionChange or Worksheet_Calculate.

var dialogName = '#dialog_XYZ';
$.ajax({
        url: "/ajax_pages/my_page.ext",
        data: {....},
        success: function(data) {
          $(dialogName ).remove();

          $('BODY').append(data);

          $(dialogName )
            .dialog(options.dialogOptions);
        }
});

The Ajax-Request load the Dialog, add them to the Body of the current page and open the Dialog.

If you only whant to load the content you can do:

var dialogName = '#dialog_XYZ';
$.ajax({
            url: "/ajax_pages/my_page.ext",
            data: {....},
            success: function(data) {
              $(dialogName).append(data);

              $(dialogName )
                .dialog(options.dialogOptions);
            }
});

I use

<div th:text ="${variable != null} ? (${variable != ''} ? ${variable} : 'empty string message') : 'null message' "></div>

The problem with all the answers is that multiplying and then dividing results in precision issues because you used division. I learned this long ago from programming on a PDP8. The way to resolve this is:

return roundf(number * 100) * .01;

Thus 15.6578 returns just 15.66 and not 15.6578999 or something unintended like that.

What level of precision you want is up to you. Just don't divide the product, multiply it by the decimal equivalent. No funny String conversion required.

This cannot be done with the native javascript dialog box, but a lot of javascript libraries include more flexible dialogs. You can use something like jQuery UI's dialog box for this.

See also these very similar questions:

• JavaScript confirm box with custom buttons
• custom choices in javascript confirm dialog

I was running JUNIT 5 and was also referencing Hamcrest external jar. But Hamcrest is also part of JUNIT 5 library. So, I have to change the order of external Hamecrest jar file up the JUNIT 5 library in build path.

In my case I had created a SB app from the SB Initializer and had included a fair number of deps in it to other things. I went in and commented out the refs to them in the build.gradle file and so was left with:

implementation 'org.springframework.boot:spring-boot-starter-hateoas'
compileOnly 'org.projectlombok:lombok'
developmentOnly 'org.springframework.boot:spring-boot-devtools'
runtimeOnly 'org.hsqldb:hsqldb'
runtimeOnly 'org.postgresql:postgresql'
annotationProcessor 'org.springframework.boot:spring-boot-configuration-processor'
annotationProcessor 'org.projectlombok:lombok'
testImplementation 'org.springframework.boot:spring-boot-starter-test'
testImplementation 'org.springframework.restdocs:spring-restdocs-mockmvc'

as deps. Then my bare-bones SB app was able to build and get running successfully. As I go to try to do things that may need those commented-out libs I will add them back and see what breaks.

    Comparator<Integer> comparator = new Comparator<Integer>() {

        @Override
        public int compare(Integer o1, Integer o2) {
            return o2.compareTo(o1);
        }
    };

    // option 1
    Integer[] array = new Integer[] { 1, 24, 4, 4, 345 };
    Arrays.sort(array, comparator);

    // option 2
    int[] array2 = new int[] { 1, 24, 4, 4, 345 };
    List<Integer>list = Ints.asList(array2);
    Collections.sort(list, comparator);
    array2 = Ints.toArray(list);

Okay, so this post is from six months ago, but I thought I would add some info here for people who are confused about the whole API key/MD5 fingerprint business. It took me a while to figure out, so I assume others have had trouble with it too (unless I'm just that dull).

These directions are for Windows XP, but I imagine it is similar for other versions of Windows. It appears Mac and Linux users have an easier time with this so I won't address them.

So in order to use mapviews in your Android apps, Google wants to check in with them so you can sign off on an Android Maps APIs Terms Of Service agreement. I think they don't want you to make any turn-by-turn GPS apps to compete with theirs or something. I didn't really read it. Oops.

So go to http://code.google.com/android/maps-api-signup.html and check it out. They want you to check the "I have read and agree with the terms and conditions" box and enter your certificate's MD5 fingerprint. Wtf is that, you might say. I don't know, but just do what I say and your Android app doesn't get hurt.

Go to Start>Run and type cmd to open up a command prompt. You need to navigate to the directory with the keytool.exe file, which might be in a slightly different place depending on which version JDK you have installed. Mine is in C:\Program Files\Java\jdk1.6.0_21\bin but try browsing to the Java folder and see what version you have and change the path accordingly.

After navigating to C:\Program Files\Java\<"your JDK version here">\bin in the command prompt, type

keytool -list -keystore "C:/Documents and Settings/<"your user name here">/.android/debug.keystore"

with the quotes. Of course <"your user name here"> would be your own Windows username.

(If you are having trouble finding this path and you are using Eclipse, you can check Window>preferences>Android>Build and check out the "Default Debug keystore")

Press enter and it will prompt you for a password. Just press enter. And voila, at the bottom is your MD5 fingerprint. Type your fingerprint into the text box at the Android Maps API Signup page and hit Generate API Key.

And there's your key in all its glory, with a handy sample xml layout with your key entered for you to copy and paste.

If you use file_put_contents you don't need to do a fopen -> fwrite -> fclose, the file_put_contents does all that for you. You should also check if the webserver has write rights in the directory where you are trying to write your "data.txt" file.

Depending on your PHP version (if it's old) you might not have the file_get/put_contents functions. Check your webserver log to see if any error appeared when you executed the script.

There is a way to accomplish this. The magic is to create a combined jacoco.exec file. And with maven 3.3.1 there is an easy way to get this. Here my profile:

The magic here is maven.multiModuleProjectDirectory. This folder is always the folder where you started your maven build.

where stateb is List'' bucket is a two dimensional array

statesb= IntStream.of(bucket[j-1]).boxed().collect(Collectors.toList());

with import java.util.stream.IntStream;

If you want to select the same item in a listbox using a listview, you can use:

Private Sub ListView1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ListView1.SelectedIndexChanged
    For aa As Integer = 0 To ListView1.SelectedItems.Count - 1
        ListBox1.SelectedIndex = ListView1.SelectedIndices(aa)
    Next
End Sub

I made this simple tool to take the place of hosts. Regular expressions are supported. https://github.com/stackia/DNSAgent

A sample configuration:

[
    {
        "Pattern": "^.*$",
        "NameServer": "8.8.8.8"
    },
    {
        "Pattern": "^(.*\\.googlevideo\\.com)|((.*\\.)?(youtube|ytimg)\\.com)$",
        "Address": "203.66.168.119"
    },
    {
        "Pattern": "^.*\\.cn$",
        "NameServer": "114.114.114.114"
    },
    {
        "Pattern": "baidu.com$",
        "Address": "127.0.0.1"
    }
]

try like this

$('title').text();

One simple method is to use readlines:

my_array = IO.readlines('filename.txt')

Each line in the input file will be an entry in the array. The method handles opening and closing the file for you.

A good idea is to set all of the "" (blank cells) to NA before any further analysis.

If you are reading your input from a file, it is a good choice to cast all "" to NAs:

foo <- read.table(file="Your_file.txt", na.strings=c("", "NA"), sep="\t") # if your file is tab delimited

If you have already your table loaded, you can act as follows:

foo[foo==""] <- NA

Then to keep only rows with no NA you may just use na.omit():

foo <- na.omit(foo)

Or to keep columns with no NA:

foo <- foo[, colSums(is.na(foo)) == 0] 

I have written an add-in for SSMS and this problem is fixed there. You can use one of 2 ways:

you can use "Copy current cell 1:1" to copy original cell data to clipboard:

http://www.ssmsboost.com/Features/ssms-add-in-copy-results-grid-cell-contents-line-with-breaks

Or, alternatively, you can open cell contents in external text editor (notepad++ or notepad) using "Cell visualizers" feature: http://www.ssmsboost.com/Features/ssms-add-in-results-grid-visualizers

(feature allows to open contents of field in any external application, so if you know that it is text - you use text editor to open it. If contents is binary data with picture - you select view as picture. Sample below shows opening a picture):

The to_char() function is there to format numbers:

select to_char(column_1, 'fm000') as column_2
from some_table;

The fm prefix ("fill mode") avoids leading spaces in the resulting varchar. The 000 simply defines the number of digits you want to have.

Most of the answers forgot about non English characters !!!

strlen counts BYTES, not characters, that is why it is and it's sibling functions works fine with English characters, because English characters are stored in 1 byte in both UTF-8 and ASCII encodings, you need to use the multibyte string functions mb_*

This will work with any character encoded in UTF-8

// 8 characters in 12 bytes
$string = "abcd????";

$charsCount = mb_strlen($string, 'UTF-8');
for($i = 0; $i < $charsCount; $i++){
    $char = mb_substr($string, $i, 1, 'UTF-8');
    var_dump($char);
}

This outputs

string(1) "a"
string(1) "b"
string(1) "c"
string(1) "d"
string(2) "?"
string(2) "?"
string(2) "?"
string(2) "?"

One thing that got this working for me is to make sure that github.com is in ~jenkins/.ssh/known_hosts.

Use the DELETE statement

Delete From <TableName>

Eg:

Delete from Student;

Forget regular expressions. JavaScript has a builtin function for this: isNaN():

isNaN(123)           // false
isNaN(-1.23)         // false
isNaN(5-2)           // false
isNaN(0)             // false
isNaN("100")         // false
isNaN("Hello")       // true
isNaN("2005/12/12")  // true

Just call it like so:

if (isNaN( $("#whatever").val() )) {
    // It isn't a number
} else {
    // It is a number
}

&& and || are what is called "short circuiting". That means that they will not evaluate the second operand if the first operand is enough to determine the value of the expression.

For example if the first operand to && is false then there is no point in evaluating the second operand, since it can't change the value of the expression (false && true and false && false are both false). The same goes for || when the first operand is true.

You can read more about this here: http://en.wikipedia.org/wiki/Short-circuit_evaluation From the table on that page you can see that && is equivalent to AndAlso in VB.NET, which I assume you are referring to.

You can easily debug such things when you go through the generated CSS. In this case the pseudo-selector after conversion has to be attached to the class. Which is not the case. Use "&".

http://sass-lang.com/documentation/file.SASS_REFERENCE.html#parent-selector

.class {
    margin:20px;
    &:hover {
        color:yellow;
    }
}

You say

The string is exactly what was written to the file (with the addition of a "\0" at the end, but I don't think that even does anything).

In fact, it does do something (it causes your code to throw a FormatException:"Invalid character in a Base-64 string") because the Convert.FromBase64String does not consider "\0" to be a valid Base64 character.

  byte[] data1 = Convert.FromBase64String("AAAA\0"); // Throws exception
  byte[] data2 = Convert.FromBase64String("AAAA");   // Works

Solution: Get rid of the zero termination. (Maybe call .Trim("\0"))

Notes:

The MSDN docs for Convert.FromBase64String say it will throw a FormatException when

The length of s, ignoring white space characters, is not zero or a multiple of 4.

-or-

The format of s is invalid. s contains a non-base 64 character, more than two padding characters, or a non-white space character among the padding characters.

and that

The base 64 digits in ascending order from zero are the uppercase characters 'A' to 'Z', lowercase characters 'a' to 'z', numerals '0' to '9', and the symbols '+' and '/'.

You can use NPOI to do it.

Workbook wb = new HSSFWorkbook();
Sheet sheet = wb.createSheet("new sheet");

Row row = sheet.createRow((short) 1);
Cell cell = row.createCell((short) 1);
cell.setCellValue("This is a test of merging");

sheet.addMergedRegion(new CellRangeAddress(
        1, //first row (0-based)
        1, //last row  (0-based)
        1, //first column (0-based)
        2  //last column  (0-based)
));

// Write the output to a file
FileOutputStream fileOut = new FileOutputStream("workbook.xls");
wb.write(fileOut);
fileOut.close();

I think I have come up with a quite shorter solution.. Hope it helps someone.

cbind.na<-function(df1, df2){

  #Collect all unique rownames
  total.rownames<-union(x = rownames(x = df1),y = rownames(x=df2))

  df<-data.frame(row.names = total.rownames)

  #Get absent rownames for both of the dataframe
  absent.names.1<-setdiff(x = rownames(df1),y = rownames(df))
  absent.names.2<-setdiff(x = rownames(df2),y = rownames(df))

Floats are used to store a wider range of number than can be fit in an integer. These include decimal numbers and scientific notation style numbers that can be bigger values than can fit in 32 bits. Here's the deep dive into them: http://en.wikipedia.org/wiki/Floating_point

You can try buslane module.

This library makes implementation of message-based system easier. It supports commands (single handler) and events (0 or multiple handlers) approach. Buslane uses Python type annotations to properly register handler.

Simple example:

from dataclasses import dataclass

from buslane.commands import Command, CommandHandler, CommandBus


@dataclass(frozen=True)
class RegisterUserCommand(Command):
    email: str
    password: str


class RegisterUserCommandHandler(CommandHandler[RegisterUserCommand]):

    def handle(self, command: RegisterUserCommand) -> None:
        assert command == RegisterUserCommand(
            email='[email protected]',
            password='secret',
        )


command_bus = CommandBus()
command_bus.register(handler=RegisterUserCommandHandler())
command_bus.execute(command=RegisterUserCommand(
    email='[email protected]',
    password='secret',
))

To install buslane, simply use pip:

$ pip install buslane

You could use the pickle module in the standard library. Here's an elementary application of it to your example:

import pickle

class Company(object):
    def __init__(self, name, value):
        self.name = name
        self.value = value

with open('company_data.pkl', 'wb') as output:
    company1 = Company('banana', 40)
    pickle.dump(company1, output, pickle.HIGHEST_PROTOCOL)

    company2 = Company('spam', 42)
    pickle.dump(company2, output, pickle.HIGHEST_PROTOCOL)

del company1
del company2

with open('company_data.pkl', 'rb') as input:
    company1 = pickle.load(input)
    print(company1.name)  # -> banana
    print(company1.value)  # -> 40

    company2 = pickle.load(input)
    print(company2.name) # -> spam
    print(company2.value)  # -> 42

You could also define your own simple utility like the following which opens a file and writes a single object to it:

def save_object(obj, filename):
    with open(filename, 'wb') as output:  # Overwrites any existing file.
        pickle.dump(obj, output, pickle.HIGHEST_PROTOCOL)

# sample usage
save_object(company1, 'company1.pkl')

Update

Since this is such a popular answer, I'd like touch on a few slightly advanced usage topics.

cPickle (or _pickle) vs pickle

It's almost always preferable to actually use the cPickle module rather than pickle because the former is written in C and is much faster. There are some subtle differences between them, but in most situations they're equivalent and the C version will provide greatly superior performance. Switching to it couldn't be easier, just change the import statement to this:

import cPickle as pickle

In Python 3, cPickle was renamed _pickle, but doing this is no longer necessary since the pickle module now does it automatically—see What difference between pickle and _pickle in python 3?.

The rundown is you could use something like the following to ensure that your code will always use the C version when it's available in both Python 2 and 3:

try:
    import cPickle as pickle
except ModuleNotFoundError:
    import pickle

Data stream formats (protocols)

pickle can read and write files in several different, Python-specific, formats, called protocols as described in the documentation, "Protocol version 0" is ASCII and therefore "human-readable". Versions > 0 are binary and the highest one available depends on what version of Python is being used. The default also depends on Python version. In Python 2 the default was Protocol version 0, but in Python 3.8.1, it's Protocol version 4. In Python 3.x the module had a pickle.DEFAULT_PROTOCOL added to it, but that doesn't exist in Python 2.

Fortunately there's shorthand for writing pickle.HIGHEST_PROTOCOL in every call (assuming that's what you want, and you usually do), just use the literal number -1 — similar to referencing the last element of a sequence via a negative index. So, instead of writing:

pickle.dump(obj, output, pickle.HIGHEST_PROTOCOL)

You can just write:

pickle.dump(obj, output, -1)

Either way, you'd only have specify the protocol once if you created a Pickler object for use in multiple pickle operations:

pickler = pickle.Pickler(output, -1)
pickler.dump(obj1)
pickler.dump(obj2)
   etc...

Note: If you're in an environment running different versions of Python, then you'll probably want to explicitly use (i.e. hardcode) a specific protocol number that all of them can read (later versions can generally read files produced by earlier ones).

Multiple Objects

While a pickle file can contain any number of pickled objects, as shown in the above samples, when there's an unknown number of them, it's often easier to store them all in some sort of variably-sized container, like a list, tuple, or dict and write them all to the file in a single call:

tech_companies = [
    Company('Apple', 114.18), Company('Google', 908.60), Company('Microsoft', 69.18)
]
save_object(tech_companies, 'tech_companies.pkl')

and restore the list and everything in it later with:

with open('tech_companies.pkl', 'rb') as input:
    tech_companies = pickle.load(input)

The major advantage is you don't need to know how many object instances are saved in order to load them back later (although doing so without that information is possible, it requires some slightly specialized code). See the answers to the related question Saving and loading multiple objects in pickle file? for details on different ways to do this. Personally I like @Lutz Prechelt's answer the best. Here's it adapted to the examples here:

class Company:
    def __init__(self, name, value):
        self.name = name
        self.value = value

def pickled_items(filename):
    """ Unpickle a file of pickled data. """
    with open(filename, "rb") as f:
        while True:
            try:
                yield pickle.load(f)
            except EOFError:
                break

print('Companies in pickle file:')
for company in pickled_items('company_data.pkl'):
    print('  name: {}, value: {}'.format(company.name, company.value))

Another way:

export default class Archive extends React.Component { 

  saySomething = (something) => {
    console.log(something);
  }

  handleClick = (e) => {
    this.saySomething("element clicked");
  }

  componentDidMount() {
    this.saySomething("component did mount");
  }

  render() {
    return <button onClick={this.handleClick} value="Click me" />;
  }
}

In this format you don't need to use bind

You cannot insert data because you have a quota of 0 on the tablespace. To fix this, run

ALTER USER <user> quota unlimited on <tablespace name>;

or

ALTER USER <user> quota 100M on <tablespace name>;

as a DBA user (depending on how much space you need / want to grant).

Open your build.gradle file and make sure you have versionCode and versionName inside defaultConfig element. If not, add them. Refer to this link for more details.

I personally prefer the "boolean1 ^ boolean2" expression due to its succinctness.

If I was in your situation (working in a team), I would strike a compromise by encapsulating the "boolean1 ^ boolean2" logic in a function with a descriptive name such as "isDifferent(boolean1, boolean2)".

For example, instead of using "boolean1 ^ boolean2", you would call "isDifferent(boolean1, boolean2)" like so:

if (isDifferent(boolean1, boolean2))
{
  //do it
}

Your "isDifferent(boolean1, boolean2)" function would look like:

private boolean isDifferent(boolean1, boolean2)
{
    return boolean1 ^ boolean2;
}

Of course, this solution entails the use of an ostensibly extraneous function call, which in itself is subject to Best Practices scrutiny, but it avoids the verbose (and ugly) expression "(boolean1 && !boolean2) || (boolean2 && !boolean1)"!

By default, the classes in the csv module use Windows-style line terminators (\r\n) rather than Unix-style (\n). Could this be what’s causing the apparent double line breaks?

If so, you can override it in the DictWriter constructor:

output = csv.DictWriter(open('file3.csv','w'), delimiter=',', lineterminator='\n', fieldnames=headers)

I'd recommend using the Buffer class:

var someEncodedString = Buffer.from('someString', 'utf-8');

This avoids any unnecessary dependencies that other answers require, since Buffer is included with node.js, and is already defined in the global scope.

Starting from Jersey 2.x, the MultivaluedMapImpl class is replaced by MultivaluedHashMap. You can use it to add form data and send it to the server:

    WebTarget webTarget = client.target("http://www.example.com/some/resource");
    MultivaluedMap<String, String> formData = new MultivaluedHashMap<String, String>();
    formData.add("key1", "value1");
    formData.add("key2", "value2");
    Response response = webTarget.request().post(Entity.form(formData));

Note that the form entity is sent in the format of "application/x-www-form-urlencoded".

Since Express.js 3x the response object has a json() method which sets all the headers correctly for you and returns the response in JSON format.

Example:

res.json({"foo": "bar"});
