Kdialog and dialog are both good, but I'd recommend Zenity. Quick, easy, and much better looking the xmessage or dialog.

You need to call srand() once, to randomize the seed, and then call rand() in your loop:

#include <stdlib.h>
#include <time.h>

#define size 10

srand(time(NULL)); // randomize seed

for(i=0;i<size;i++)
    Arr[i] = rand()%size;

I have had the similar problem. Moving the JDK and JRE path to the top of the path variable solved the problem (which takes first priority over what is present under System32)

For example, here is mine:

As etienne said be sure that the XML file you are looking at is in src/main/res/layout

I had the same issue. If you're in a layout file in build directory, you won't see a preview, nor will you have it as an option to enable. I wish Google had a slight warning for it.

if(array.indexOf("67") != -1) // is in array

In laymen language we can say:

• Clone: Get a working copy of the remote repository.
• Pull: I am working on this, please get me the new changes that may be updated by others.

For most use cases, what about

from datetime import date

current_date =date.today()
current_month = current_date.month
last_month = current_month - 1 if current_month != 1 else 12  
today_a_month_ago = date(current_date.year, last_month, current_date.day)

That seems the simplest to me.

Note: I've added the second to last line so that it would work if the current month is January as per @Nick's comment

Note 2: In most cases, if the current date is the 31st of a given month the result will be an invalid date as the previous month would not have 31 days (Except for July & August), as noted by @OneCricketeer

If you start execution with gc logging turned on you get the info on file. Otherwise 'jmap -heap ' will give you what you want. See the jmap doc page for more.

Please note that jmap should not be used in a production environment unless absolutely needed as the tool halts the application to be able to determine actual heap usage. Usually this is not desired in a production environment.

SQL Server Express does not come with profiler, but you can use SQL Server 2005/2008 Express Profiler instead.

To download the wsdl from a url using Developer Command Prompt for Visual Studio, run it in Administrator mode and enter the following command:

 svcutil /t:metadata http://[your-service-url-here]

You can now consume the downloaded wsdl in your project as you see fit.

In case you are building a jar with scala 2.11 and Apache 2.0 or higher.

There is no need to create a sqlContext or sparkContext object. Just a SparkSession object suffices the requirement for all needs.

Following is mycode which works fine:

import org.apache.spark.sql.{DataFrame, Row, SQLContext, SparkSession}
import org.apache.log4j.{Level, LogManager, Logger}

object driver {

  def main(args: Array[String]) {

    val log = LogManager.getRootLogger

    log.info("**********JAR EXECUTION STARTED**********")

    val spark = SparkSession.builder().master("local").appName("ValidationFrameWork").getOrCreate()
    val df = spark.read.format("csv")
      .option("header", "true")
      .option("delimiter","|")
      .option("inferSchema","true")
      .load("d:/small_projects/spark/test.pos")
    df.show()
  }
}

In case you are running in cluster just change .master("local") to .master("yarn") while defining the sparkBuilder object

The Spark Doc covers this: https://spark.apache.org/docs/2.2.0/sql-programming-guide.html

If you want to enable debug logging in tomcat for TLD scanned jars then you have to change /conf/logging.properties file in tomcat directory.

uncomment the line :
org.apache.jasper.servlet.TldScanner.level = FINE

FINE level is for debug log.

This should work for normal tomcat.

If the tomcat is running under eclipse. Then you have to set the path of tomcat logging.properties in eclipse.

1. Open servers view in eclipse.Stop the server.Double click your tomcat server.
   This will open Overview window for the server.
2. Click on Open launch configuration.This will open another window.
3. Go to the Arguments tab(second tab).Go to VM arguments section.
4. paste this two line there :-
   -Djava.util.logging.config.file="{CATALINA_HOME}\conf\logging.properties"
   -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager
   Here CATALINA_HOME is your PC's corresponding tomcat server directory.
5. Save the Changes.Restart the server.

Now the jar files that scanned for TLDs should show in the log.

 <?php
              $selectdata ="select fromd,tod  from register where username='$username'";
            $q=mysqli_query($conm,$selectdata);
            $row=mysqli_fetch_array($q);

            $startdate=$row['fromd']; 
            $stdate=date('Y', strtotime($startdate));  

            $endate=$row['tod']; 
            $enddate=date('Y', strtotime($endate));  

            $years = range ($stdate,$enddate);
            echo '<select name="years" class="form-control">';
            echo '<option>SELECT</option>';
            foreach($years as $year)
              {   echo '<option value="'.$year.'"> '.$year.' </option>';  }
                echo '</select>'; ?>

Compromise minimum solution:

| One    | Two | Three | Four    | Five  | Six

So you can omit closing </td> for speed, ?r can leave for consistency.

Put your class name on the mat-form-field element. This works for all inputs.

All solutions seems to be complicated. I'm looking for the simplest solution for this case and I just want to use constants. Constants are simple. Is there anything which speaks against the following solution?

app.const.ts

'use strict';

export const dist = '../path/to/dist/';

app.service.ts

import * as AppConst from '../app.const'; 

@Injectable()
export class AppService {

    constructor (
    ) {
        console.log('dist path', AppConst.dist );
    }

}

My answer is based on getting a 403 error although I had all of the Apache settings mentioned in the other answers correct.

It was a fresh Centos 7 server and it turned out that the issue was not the Apache settings but the fact that the PhpMyAdmin did not serve at all. The solution was to install php and add the php directive to apache.conf:

• sudo yum install php php-mysql
• vim /etc/httpd/conf/httpd.conf add something like
• DirectoryIndex index.php index.phtml index.html index.htm to serve php index files also and then restart apache

Don't forget to restart Apache server to take effect - systemctl restart httpd.service

I hope this helps. I first thought my issue was Apache directives, so I post my solution here.

You can add a facade in your folder\config\app.php

'Input' => Illuminate\Support\Facades\Input::class,

You could simply return a value from the function:

var response = 0;

function doSomething() {
    // some code
    return 10;
}
response = doSomething();

I used before so many times for getting @attributes like below and it was a little bit longer.

$att = $xml->attributes();
echo $att['field'];

It should be more easy and you can get attributes following format only at once:

Standard Way - Array-Access Attributes (AAA)

$xml['field'];

Other alternatives are:

Right & Quick Format

$xml->attributes()->{'field'};

Wrong Formats

$xml->attributes()->field;
$xml->{"@attributes"}->field;
$xml->attributes('field');
$xml->attributes()['field'];
$xml->attributes->['field'];

For MySQL, please find the below query:

select * from (select PartID, max(Pricedate) max_pricedate from MyPrices group bu partid) as a 
    inner join MyParts b on
    (a.partid = b.partid and a.max_pricedate = b.pricedate)

Inside the subquery it fetches max pricedate for every partyid of MyPrices then, inner joining with MyParts using partid and the max_pricedate

        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        listview = (ListView) findViewById(R.id.listview);
        listview.setAdapter(new yourAdapter(this, new String[] { "data1",
                "data2" }));
    }
}

the results

I got this exception because I was trying to make a Toast popup from a background thread.
Toast needs an Activity to push to the user interface and threads don't have that.
So one workaround is to give the thread a link to the parent Activity and Toast to that.

Put this code in the thread where you want to send a Toast message:

parent.runOnUiThread(new Runnable() {
    public void run() {
        Toast.makeText(parent.getBaseContext(), "Hello", Toast.LENGTH_LONG).show();
    }
});

Keep a link to the parent Activity in the background thread that created this thread. Use parent variable in your thread class:

private static YourActivity parent;

When you create the thread, pass the parent Activity as a parameter through the constructor like this:

public YourBackgroundThread(YourActivity parent) {
    this.parent = parent;
}

Now the background thread can push Toast messages to the screen.

simple way to do 'groupby' and sorting in descending order

df.groupby(['companyName'])['overallRating'].sum().sort_values(ascending=False).head(20)

In ruby/python/c, you can concatenate strings just like this:

a = "foo" "bar"
print a # => "foobar"

That problem would be a nice demonstration for use of closures. The idea is that a function uses a variable of outer scope. Here is an example...

setInterval(makeClosure("Snowden"), 1000)

function makeClosure(name) {
var ret

ret = function(){
    console.log("Hello, " + name);
}

return ret;
}

Function "makeClosure" returns another function, which has access to outer scope variable "name". So, basically, you need pass in whatever variables to "makeClosure" function and use them in function assigned to "ret" variable. Affectingly, setInterval will execute function assigned to "ret".

If your collection type is a List<stuff>, then the best approach is probably the following:

prods.RemoveAll(s => s.ID == 1)

This only does one pass (iteration) over the list, so should be more efficient than other methods.

If your type is more generically an ICollection<T>, it might help to write a short extension method if you care about performance. If not, then you'd probably get away with using LINQ (calling Where or Single).

I just like to note that I needed this for my Cucumber tests and found out that if you like to simulate pressing the enter/return key, you need to send the :return value and not the :enter value (see the values described here)

As you want to specifically search for a wildcard character you need to escape that

This is done by adding the ESCAPE clause to your LIKE expression. The character that is specified with the ESCAPE clause will "invalidate" the following wildcard character.

You can use any character you like (just not a wildcard character). Most people use a \ because that is what many programming languages also use

So your query would result in:

select * 
from Manager
where managerid LIKE '\_%' escape '\'
and managername like '%\_%' escape '\';

But you can just as well use any other character:

select * 
from Manager
where managerid LIKE '#_%' escape '#'
and managername like '%#_%' escape '#';

Here is an SQLFiddle example: http://sqlfiddle.com/#!6/63e88/4

One line code for Done button:-

[yourTextField setReturnKeyType:UIReturnKeyDone];

And add action method on valueChanged of TextField and add this line-

[yourTextField resignFirstResponder];

You can do it in this way with Swift 3.0:

let calendar = Calendar.current
let components = calendar.dateComponents([.year, .month, .day], from: date)

let year =  components.year
let month = components.month
let day = components.day

print(year)
print(month)
print(day)

$(document).ready(function(){
  var date = new Date();

  var day = ("0" + date.getDate()).slice(-2); var month = ("0" + (date.getMonth() + 1)).slice(-2);

  var today = date.getFullYear()+"-"+(month)+"-"+(day) ;
});

$('#dateid').val(today);

File outputfile = new File("image.jpg");
ImageIO.write(bufferedImage, "jpg", outputfile);

You can do it in one line:

ls /home/edward/bank1/fiche/Test* >/dev/null 2>&1 && echo "found one" || echo "found none"

To understand what it does you have to decompose the command and have a basic awareness of boolean logic.

Directly from bash man page:

[...]
expression1 && expression2
     True if both expression1 and expression2 are true.
expression1 || expression2
     True if either expression1 or expression2 is true.
[...]

In the shell (and in general in unix world), the boolean true is a program that exits with status 0.

ls tries to list the pattern, if it succeed (meaning the pattern exists) it exits with status 0, 2 otherwise (have a look at ls man page for details).

In our case there are actually 3 expressions, for the sake of clarity I will put parenthesis, although they are not needed because && has precedence on ||:

 (expression1 && expression2) || expression3

so if expression1 is true (ie: ls found the pattern) it evaluates expression2 (which is just an echo and will exit with status 0). In this case expression3 is never evaluate because what's on the left site of || is already true and it would be a waste of resources trying to evaluate what's on the right.

Otherwise, if expression1 is false, expression2 is not evaluated but in this case expression3 is.

$('#select').val('defaultValue'); 
$('#select').change();

This will also trigger events hooked to this select

put the logic in

afterTextChanged(Editable s) {
    string str = s.toString()
    // use the string str
}

setInterval(function(){$("#myButtonId").click();}, 1000);

A URL must not contain a literal space. It must either be encoded using the percent-encoding or a different encoding that uses URL-safe characters (like application/x-www-form-urlencoded that uses + instead of %20 for spaces).

But whether the statement is right or wrong depends on the interpretation: Syntactically, a URI must not contain a literal space and it must be encoded; semantically, a %20 is not a space (obviously) but it represents a space.

Simplest method when not using an emulator

$ adb shell
$ run-as your.package.name
$ chmod 777 databases
$ chmod 777 databases/database_name
$ exit
$ cp /data/data/your.package.name/databases/database_name /sdcard
$ run-as your.package.name # Optional
$ chmod 660 databases/database_name # Optional
$ chmod 660 databases # Optional
$ exit # Optional
$ exit
$ adb pull /sdcard/database_name

Caveats:

I haven't tested this in a while. It may not work on API>=25. If the cp command isn't working for you try one of the following instead:

# Pick a writeable directory <dir> other than /sdcard
$ cp /data/data/your.package.name/databases/database_name <dir>

# Exit and pull from the terminal on your PC
$ exit
$ adb pull /data/data/your.package.name/databases/database_name

Explanation:

The first block configures the permissions of your database to be readable. This leverages run-as which allows you to impersonate your package's user to make the change.

$ adb shell
$ run-as your.package.name
$ chmod 777 databases
$ chmod 777 databases/database_name
$ exit # Closes the shell started with run-as

Next we copy the database to a world readable/writeable directory. This allows the adb pull user access.

$ cp /data/data/your.package.name/databases/database_name /sdcard

Then, replace the existing read/write privileges. This is important for the security of your app, however the privileges will be replaced on the next install.

$ run-as your.package.name
$ chmod 660 databases/database_name 
$ chmod 660 databases
$ exit # Exit the shell started with run-as

Finally, copy the database to the local disk.

$ exit # Exits shell on the mobile device (from adb shell) 
$ adb pull /sdcard/database_name

The existing answers are valid, but why re-invent the wheel and bother with lower level WebRequest types while WebClient already implements FTP uploading neatly:

using (var client = new WebClient())
{
    client.Credentials = new NetworkCredential(ftpUsername, ftpPassword);
    client.UploadFile("ftp://host/path.zip", WebRequestMethods.Ftp.UploadFile, localFile);
}

two reasons I can think of:

Technical reason

The object exists only after the constructor ends.In order for the constructor to be dispatched using the virtual table , there has to be an existing object with a pointer to the virtual table , but how can a pointer to the virtual table exist if the object still doesn't exist? :)

Logic reason

You use the virtual keyword when you want to declare a somewhat polymorphic behaviour. But there is nothing polymorphic with constructors , constructors job in C++ is to simply put an object data on the memory . Since virtual tables (and polymorphism in general) are all about polymorphic behaviour rather on polymorphic data , There is no sense with declaring a virtual constructor.

...you may also want to check for cross site scripting issues...if your html pages comes from a different domain/port combi then your rest service, your browser may block the call.

Typically, right mouse->inspect on your html page. Then look in the error console for errors like

Access to XMLHttpRequest at '...:8080' from origin '...:8383' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

From CREATE FUNCTION:

When a parameter of the function has a default value, the keyword DEFAULT must be specified when the function is called to retrieve the default value. This behavior is different from using parameters with default values in stored procedures in which omitting the parameter also implies the default value.

So you need to do:

SELECT dbo.fCalculateEstimateDate(647,DEFAULT)

This way you don't have to manage the details of leap years and daylight saving.

It was removed on purpose and it won't be coming back.

Both chrome://cache and chrome://view-http-cache have been removed starting chrome 66. They work in version 65.

Workaround

You can check the chrome://chrome-urls/ for complete list of internal Chrome URLs.

The only workaround that comes into my mind is to use menu/more tools/developer tools and having a Network tab selected.

The reason why it was removed is this bug:

• https://chromium.googlesource.com/chromium/src.git/+/6ebc11f6f6d112e4cca5251d4c0203e18cd79adc
• https://bugs.chromium.org/p/chromium/issues/detail?id=811956

With base graphics, the easiest way is to stop the plotting functions from drawing axes and then draw them yourself.

plot(1:10, 1:10, axes = FALSE)
axis(side = 1, at = c(1,5,10))
axis(side = 2, at = c(1,3,7,10))
box()

Here's how you can use it:

New_Fun.h

#ifndef NEW_FUN_H_
#define NEW_FUN_H_

#include <stdio.h>

typedef int speed;
speed fun(int x);

enum fp {
    f1, f2, f3, f4, f5
};

void F1();
void F2();
void F3();
void F4();
void F5();
#endif

New_Fun.c

#include "New_Fun.h"

speed fun(int x)
{
    int Vel;
    Vel = x;
    return Vel;
}

void F1()
{
    printf("From F1\n");
}

void F2()
{
    printf("From F2\n");
}

void F3()
{
    printf("From F3\n");
}

void F4()
{
    printf("From F4\n");
}

void F5()
{
    printf("From F5\n");
}

Main.c

#include <stdio.h>
#include "New_Fun.h"

int main()
{
    int (*F_P)(int y);
    void (*F_A[5])() = { F1, F2, F3, F4, F5 };    // if it is int the pointer incompatible is bound to happen
    int xyz, i;

    printf("Hello Function Pointer!\n");
    F_P = fun;
    xyz = F_P(5);
    printf("The Value is %d\n", xyz);
    //(*F_A[5]) = { F1, F2, F3, F4, F5 };
    for (i = 0; i < 5; i++)
    {
        F_A[i]();
    }
    printf("\n\n");
    F_A[f1]();
    F_A[f2]();
    F_A[f3]();
    F_A[f4]();
    return 0;
}

I hope this helps in understanding Function Pointer.

You can simulate this problem with a syntax mistake, however, %matplotlib inline won't resolve the issue.

First an example of the right way to create a plot. Everything works as expected with the imports and magic that eNord9 supplied.

df_randNumbers1 = pd.DataFrame(np.random.randint(0,100,size=(100, 6)), columns=list('ABCDEF'))

df_randNumbers1.ix[:,["A","B"]].plot.kde()

However, by leaving the () off the end of the plot type you receive a somewhat ambiguous non-error.

Erronious code:

df_randNumbers1.ix[:,["A","B"]].plot.kde

Example error:

<bound method FramePlotMethods.kde of <pandas.tools.plotting.FramePlotMethods object at 0x000001DDAF029588>>

Other than this one line message, there is no stack trace or other obvious reason to think you made a syntax error. The plot doesn't print.

You're talking about histograms, but this doesn't quite make sense. Histograms and bar charts are different things. An histogram would be a bar chart representing the sum of values per year, for example. Here, you just seem to be after bars.

Here is a complete example from your data that shows a bar of for each required value at each date:

import pylab as pl
import datetime

data = """0 14-11-2003
1 15-03-1999
12 04-12-2012
33 09-05-2007
44 16-08-1998
55 25-07-2001
76 31-12-2011
87 25-06-1993
118 16-02-1995
119 10-02-1981
145 03-05-2014"""

values = []
dates = []

for line in data.split("\n"):
    x, y = line.split()
    values.append(int(x))
    dates.append(datetime.datetime.strptime(y, "%d-%m-%Y").date())

fig = pl.figure()
ax = pl.subplot(111)
ax.bar(dates, values, width=100)
ax.xaxis_date()

You need to parse the date with strptime and set the x-axis to use dates (as described in this answer).

If you're not interested in having the x-axis show a linear time scale, but just want bars with labels, you can do this instead:

fig = pl.figure()
ax = pl.subplot(111)
ax.bar(range(len(dates)), values)

EDIT: Following comments, for all the ticks, and for them to be centred, pass the range to set_ticks (and move them by half the bar width):

fig = pl.figure()
ax = pl.subplot(111)
width=0.8
ax.bar(range(len(dates)), values, width=width)
ax.set_xticks(np.arange(len(dates)) + width/2)
ax.set_xticklabels(dates, rotation=90)

Example of using a Timer:

using System;
using System.Timers;

static void Main(string[] args)
{
    Timer t = new Timer(TimeSpan.FromMinutes(5).TotalMilliseconds); // Set the time (5 mins in this case)
    t.AutoReset = true;
    t.Elapsed += new System.Timers.ElapsedEventHandler(your_method);
    t.Start();
}

// This method is called every 5 mins
private static void your_method(object sender, ElapsedEventArgs e)
{
    Console.WriteLine("..."); 
}

Simply, Dictionary<TKey,TValue> is a generic type, allowing:

• static typing (and compile-time verification)
• use without boxing

If you are .NET 2.0 or above, you should prefer Dictionary<TKey,TValue> (and the other generic collections)

A subtle but important difference is that Hashtable supports multiple reader threads with a single writer thread, while Dictionary offers no thread safety. If you need thread safety with a generic dictionary, you must implement your own synchronization or (in .NET 4.0) use ConcurrentDictionary<TKey, TValue>.

Unset will destroy a particular session variable whereas session_destroy() will destroy all the session data for that user.

It really depends on your application as to which one you should use. Just keep the above in mind.

unset($_SESSION['name']); // will delete just the name data

session_destroy(); // will delete ALL data associated with that user.

Just include this line

android:selectAllOnFocus="false"

in the XML segment corresponding to the EditText layout.

I think it's too late to answer this question but I faced the same problem recently my use case was to call the paginated JSON API and get all the data from each pagination and append it to a single array.

const https = require('https');
const apiUrl = "https://example.com/api/movies/search/?Title=";
let finaldata = [];
let someCallBack = function(data){
  finaldata.push(...data);
  console.log(finaldata);
};
const getData = function (substr, pageNo=1, someCallBack) {

  let actualUrl = apiUrl + `${substr}&page=${pageNo}`;
  let mydata = []
  https.get(actualUrl, (resp) => {
    let data = '';
    resp.on('data', (chunk) => {
        data += chunk;
    });
    resp.on('end', async () => {
        if (JSON.parse(data).total_pages!==null){
          pageNo+=1;
          somCallBack(JSON.parse(data).data);
          await getData(substr, pageNo, someCallBack);
        }
    });
  }).on("error", (err) => {
      console.log("Error: " + err.message);
  });
}

getData("spiderman", pageNo=1, someCallBack);

Like @ackuser mentioned we can use other module but In my use case I had to use the node https. Hoping this will help others.

Query in Parado's answer is correct, if you want to use MySql too instead GETDATE() you must use (because you've tagged this question with Sql server and Mysql):

select * from tab
where DateCol between adddate(now(),-7) and now() 

&& lets you do something based on whether the previous command completed successfully - that's why you tend to see it chained as do_something && do_something_else_that_depended_on_something.

You are using a function, which is marked as deleted.
Eg:

int doSomething( int ) = delete;

The =delete is a new feature of C++0x. It means the compiler should immediately stop compiling and complain "this function is deleted" once the user use such function.

If you see this error, you should check the function declaration for =delete.

To know more about this new feature introduced in C++0x, check this out.

You could use the JPA LOCATE function.

LOCATE(searchString, candidateString [, startIndex]): Returns the first index of searchString in candidateString. Positions are 1-based. If the string is not found, returns 0.

FYI: The documentation on my top google hit had the parameters reversed.

SELECT 
  e
FROM 
  entity e
WHERE
  (0 < LOCATE(:searchStr, e.property))

I had a need for an extended version of this: instead of embedding a single number in a string, I needed to generate a series of file names of the form 'file1.pdf', 'file2.pdf' etc. This is how it worked:

['file' + str(i) + '.pdf' for i in range(1,4)]

You can open the preferences (multiple options):

• keyboard shortcut Ctrl + Alt + Shift + P
• Tools -> Preferences

And depending on the Spyder version you can change the interpreter in the Python interpreter section (Spyder 3.x):

or in the advanced Console section (Spyder 2.x):

What you are probably really wanting to do here is use the union operator like this:

(select ID from Logo where AccountID = 1 and Rendered = 'True')
  union
  (select ID from Design where AccountID = 1 and Rendered = 'True')
  order by ID limit 0, 51

Here's the docs for it https://dev.mysql.com/doc/refman/5.0/en/union.html

Even though this question asked is old, note that changing a UUID on a virtual HDD in a windows system will make windows treat it as a not activated machine (as it notices the disk change) and will ask for reactivation !

The purpose of data-toggle in bootstrap is so you can use jQuery to find all tags of a certain type. For example, you put data-toggle="popover" in all popover tags and then you can use a JQuery selector to find all those tags and run the popover() function to initialize them. You could just as well put class="myPopover" on the tag and use the .myPopover selector to do the same thing. The documentation is confusing, because it makes it appear that something special is going on with that attribute.

This

<div class="container">
    <h3>Popover Example</h3>
    <a href="#" class="myPop" title="Popover1 Header" data-content="Some content inside the popover1">Toggle popover1</a>
    <a href="#" class="myPop" title="Popover2 Header" data-content="Some content inside the popover2">Toggle popover2</a>
</div>

<script>
    $(document).ready(function(){
        $('.myPop').popover();   
    });
</script>

works just fine.

Use CultureInfo class to change your culture info.

var dutchCultureInfo = CultureInfo.CreateSpecificCulture("nl-NL");
var date1 = DateTime.ParseExact(date, "dd.MM.yyyy HH:mm:ss", dutchCultureInfo);

NetBeans is pretty nice because it has syntax highlighting, tabs, auto-formatting and live syntax verification. Sadly, you cannot save in UTF-8 without having to set up "projects".

How annoying, I wonder if there is another editor that has syntax highlighting, tabs, auto-formatting and live syntax verification but would also allow me to use UTF-8 without having to set up "projects".

I just implement this myself in a project, see code below. As mentions by @Christopher Pickslay it is important to remember that functions are first class citizens and can therefore be treated like optional variables.

@objc protocol ContactDetailsDelegate: class {

    optional func deleteContact(contact: Contact) -> NSError?
}

...

weak var delegate:ContactDetailsDelegate!

if let deleteContact = delegate.deleteContact {
    deleteContact(contact)
}

Which parameter between (data / json / files) should be used,it's actually depends on a request header named ContentType(usually check this through developer tools of your browser),

when the Content-Type is application/x-www-form-urlencoded, code should be:

requests.post(url, data=jsonObj)

when the Content-Type is application/json, your code is supposed to be one of below:

requests.post(url, json=jsonObj)

requests.post(url, data=jsonstr, headers={"Content-Type":"application/json"})

when the Content-Type is multipart/form-data, it's used to upload files, so your code should be:

requests.post(url, files=xxxx)

>>> s1 ='arbit'
>>> s2 = 'hello world '.join( [s]*3 )
>>> print s2
arbit hello world arbit hello world arbit

This is the easiest way to do what you are trying to do:

On windows use the name of the table in quotes: TABLE "user"; or SELECT * FROM "user";

Beginning in Lollipop, there is a method called ImageView#setImageTintList() that you can use... the advantage being that it takes a ColorStateList as opposed to just a single color, thus making the image's tint state-aware.

On pre-Lollipop devices, you can get the same behavior by tinting the drawable and then setting it as the ImageView's image drawable:

ColorStateList csl = AppCompatResources.getColorStateList(context, R.color.my_clr_selector);
Drawable drawable = DrawableCompat.wrap(imageView.getDrawable());
DrawableCompat.setTintList(drawable, csl);
imageView.setImageDrawable(drawable);

If you are sure that the required substring is present in the string, then this will replace the first occurence of "abc" to "hij"

test.replace( test.find("abc"), 3, "hij");

It will crash if you dont have "abc" in test, so use it with care.

this is the path to the web root directory c:\wamp\www

you can create different projects by adding different folders to this directory and call them like:

localhost/project1 from browser

this will run the index.html or index.php, lying inside project1

I was also faced by the posted issue when I used python 2.7. It is working very fine with python 3.4

To make it work in python 2.7 I have added the __metaclass__ = type attribute at the top of my program and it worked.

__metaclass__ : It eases the transition from old-style classes and new-style classes.

Go to data_dir and remove the Your_table.TMP file after repairing <Your_table> table.

Dispose simply gets called when you leave the scope of using. The intention of "using" is to give developers a guaranteed way to make sure that resources get disposed.

From MSDN:

A using statement can be exited either when the end of the using statement is reached or if an exception is thrown and control leaves the statement block before the end of the statement.

By default mongodb has no enabled access control, so there is no default user or password.

To enable access control, use either the command line option --auth or security.authorization configuration file setting.

You can use the following procedure or refer to Enabling Auth in the MongoDB docs.

Procedure

1. Start MongoDB without access control.

   mongod --port 27017 --dbpath /data/db1
   

2. Connect to the instance.

   mongo --port 27017
   

3. Create the user administrator.

   use admin
   db.createUser(
     {
       user: "myUserAdmin",
       pwd: "abc123",
       roles: [ { role: "userAdminAnyDatabase", db: "admin" } ]
     }
   )
   

4. Re-start the MongoDB instance with access control.

   mongod --auth --port 27017 --dbpath /data/db1
   

5. Authenticate as the user administrator.

   mongo --port 27017 -u "myUserAdmin" -p "abc123" \
     --authenticationDatabase "admin"
   

Approach 4 (this is extension of wild coder answer)

txtName.disabled=1     // 0 for enable

<input id="txtName">

There are several approaches to customize the error handling behavior with JAX-RS. Here are three of the easier ways.

The first approach is to create an Exception class that extends WebApplicationException.

Example:

public class NotAuthorizedException extends WebApplicationException {
     public NotAuthorizedException(String message) {
         super(Response.status(Response.Status.UNAUTHORIZED)
             .entity(message).type(MediaType.TEXT_PLAIN).build());
     }
}

And to throw this newly create Exception you simply:

@Path("accounts/{accountId}/")
    public Item getItem(@PathParam("accountId") String accountId) {
       // An unauthorized user tries to enter
       throw new NotAuthorizedException("You Don't Have Permission");
}

Notice, you don't need to declare the exception in a throws clause because WebApplicationException is a runtime Exception. This will return a 401 response to the client.

The second and easier approach is to simply construct an instance of the WebApplicationException directly in your code. This approach works as long as you don't have to implement your own application Exceptions.

Example:

@Path("accounts/{accountId}/")
public Item getItem(@PathParam("accountId") String accountId) {
   // An unauthorized user tries to enter
   throw new WebApplicationException(Response.Status.UNAUTHORIZED);
}

This code too returns a 401 to the client.

Of course, this is just a simple example. You can make the Exception much more complex if necessary, and you can generate what ever http response code you need to.

One other approach is to wrap an existing Exception, perhaps an ObjectNotFoundException with an small wrapper class that implements the ExceptionMapper interface annotated with a @Provider annotation. This tells the JAX-RS runtime, that if the wrapped Exception is raised, return the response code defined in the ExceptionMapper.

To offer an update on the situation on Q2 of 2017.

A new CSS3 display property is available in Firefox 53, Chrome 58 and Opera 45.

.clearfix {
   display: flow-root;
}

Check the availability for any browser here: http://caniuse.com/#feat=flow-root

The element (with a display property set to flow-root) generates a block container box, and lays out its contents using flow layout. It always establishes a new block formatting context for its contents.

Meaning that if you use a parent div containing one or several floating children, this property is going to ensure the parent encloses all of its children. Without any need for a clearfix hack. On any children, nor even a last dummy element (if you were using the clearfix variant with :before on the last children).

.container {_x000D_
  display: flow-root;_x000D_
  background-color: Gainsboro;_x000D_

.item3 {  _x000D_
  height: 160px;_x000D_

}

<div class="container">_x000D_
  This container box encloses all of its floating children._x000D_
  <div class="item item1">Floating box 1</div>_x000D_

I had this problem and it turned out I was trying to restore to the wrong version of SQL. If you want more information on what's going on, try restoring the database using the following SQL:

RESTORE DATABASE <YourDatabase> 
FROM DISK='<the path to your backup file>\<YourDatabase>.bak'

That should give you the error message that you need to debug this.

i am use following construction to convert back nl2br

function br2nl( $input ) {
    return preg_replace('/<br\s?\/?>/ius', "\n", str_replace("\n","",str_replace("\r","", htmlspecialchars_decode($input))));
}

here i replaced \n and \r symbols from $input because nl2br dosen't remove them and this causes wrong output with \n\n or \r<br>.

If your code doesn't cross filesystem boundaries, i.e. you're just working with one filesystem, then use java.io.File.separator.

This will, as explained, get you the default separator for your FS. As Bringer128 explained, System.getProperty("file.separator") can be overriden via command line options and isn't as type safe as java.io.File.separator.

The last one, java.nio.file.FileSystems.getDefault().getSeparator(); was introduced in Java 7, so you might as well ignore it for now if you want your code to be portable across older Java versions.

So, every one of these options is almost the same as others, but not quite. Choose one that suits your needs.

Check this one (Password should be password):

<wsse:UsernameToken xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd" wsu:Id="SecurityToken-6138db82-5a4c-4bf7-915f-af7a10d9ae96">

  <wsu:Created>2010-06-08T07:26:50Z</wsu:Created>
</wsse:UsernameToken>

Following command will list down all the files having exact name "pattern" (for example) in current and its sub folders.

find ./ -name "pattern"

Use command

google-chrome-stable

We can also use command

google-chrome

To open terminal but in my case when I make an interrupt ctrl + c then it get closed so I would recommend to use google-chrome-stable instead of google-chrome

Pfft! Microseconds! Never solve a problem in microseconds that can be solved in nanoseconds.

Note that the accepted answer:

• iterates over the whole data, regardless of whether a nan is found
• creates a temporary array of size N, which is redundant.

A better solution is to return True immediately when NAN is found:

import numba
import numpy as np

NAN = float("nan")

@numba.njit(nogil=True)
def _any_nans(a):
    for x in a:
        if np.isnan(x): return True
    return False

@numba.jit
def any_nans(a):
    if not a.dtype.kind=='f': return False
    return _any_nans(a.flat)

array1M = np.random.rand(1000000)
assert any_nans(array1M)==False
%timeit any_nans(array1M)  # 573us

array1M[0] = NAN
assert any_nans(array1M)==True
%timeit any_nans(array1M)  # 774ns  (!nanoseconds)

and works for n-dimensions:

array1M_nd = array1M.reshape((len(array1M)/2, 2))
assert any_nans(array1M_nd)==True
%timeit any_nans(array1M_nd)  # 774ns

Compare this to the numpy native solution:

def any_nans(a):
    if not a.dtype.kind=='f': return False
    return np.isnan(a).any()

array1M = np.random.rand(1000000)
assert any_nans(array1M)==False
%timeit any_nans(array1M)  # 456us

array1M[0] = NAN
assert any_nans(array1M)==True
%timeit any_nans(array1M)  # 470us

%timeit np.isnan(array1M).any()  # 532us

The early-exit method is 3 orders or magnitude speedup (in some cases). Not too shabby for a simple annotation.

You're already doing it!

save() will check if something in the model has changed. If it hasn't it won't run a db query.

Here's the relevant part of code in Illuminate\Database\Eloquent\Model@performUpdate:

protected function performUpdate(Builder $query, array $options = [])
{
    $dirty = $this->getDirty();

    if (count($dirty) > 0)
    {
        // runs update query
    }

    return true;
}

The getDirty() method simply compares the current attributes with a copy saved in original when the model is created. This is done in the syncOriginal() method:

public function __construct(array $attributes = array())
{
    $this->bootIfNotBooted();

    $this->syncOriginal();

    $this->fill($attributes);
}

public function syncOriginal()
{
    $this->original = $this->attributes;

    return $this;
}

If you want to check if the model is dirty just call isDirty():

if($product->isDirty()){
    // changes have been made
}

Or if you want to check a certain attribute:

if($product->isDirty('price')){
    // price has changed
}

You can use os.stat(path) call

http://docs.python.org/library/os.html#os.stat

This is offtopic here but the people over at CodeReview are more than happy to help you.

I strongly suggest you to do so, there are several things that need attention in your code. Likewise I suggest that you do start reading tutorials since there is really no good reason not to do so.

Lists:

As you said yourself: you need a list of items. The way it is now you only store a reference to one item. Lucky there is exactly that to hold a group of related objects: a List.

Lists are very straightforward to use but take a look at the related documentation anyway.

A very simple example to keep multiple bikes in a list:

List<Motorbike> bikes = new List<Motorbike>();

bikes.add(new Bike { make = "Honda", color = "brown" });
bikes.add(new Bike { make = "Vroom", color = "red" });

And to iterate over the list you can use the foreach statement:

foreach(var bike in bikes) {
     Console.WriteLine(bike.make);
}

You could do $stmt->queryString to obtain the SQL query used in the statement. If you want to save the entire $stmt variable (I can't see why), you could just copy it. It is an instance of PDOStatement so there is apparently no advantage in storing it.

Actually you are right: it runs another instance of make. A possible solution would be:

.PHONY : clearscr fresh clean all

all :
    compile executable

clean :
    rm -f *.o $(EXEC)

fresh : clean clearscr all

clearscr:
    clear

By calling make fresh you get first the clean target, then the clearscreen which runs clear and finally all which does the job.

EDIT Aug 4

What happens in the case of parallel builds with make’s -j option? There's a way of fixing the order. From the make manual, section 4.2:

Occasionally, however, you have a situation where you want to impose a specific ordering on the rules to be invoked without forcing the target to be updated if one of those rules is executed. In that case, you want to define order-only prerequisites. Order-only prerequisites can be specified by placing a pipe symbol (|) in the prerequisites list: any prerequisites to the left of the pipe symbol are normal; any prerequisites to the right are order-only: targets : normal-prerequisites | order-only-prerequisites

The normal prerequisites section may of course be empty. Also, you may still declare multiple lines of prerequisites for the same target: they are appended appropriately. Note that if you declare the same file to be both a normal and an order-only prerequisite, the normal prerequisite takes precedence (since they are a strict superset of the behavior of an order-only prerequisite).

Hence the makefile becomes

.PHONY : clearscr fresh clean all

all :
    compile executable

clean :
    rm -f *.o $(EXEC)

fresh : | clean clearscr all

clearscr:
    clear

EDIT Dec 5

It is not a big deal to run more than one makefile instance since each command inside the task will be a sub-shell anyways. But you can have reusable methods using the call function.

log_success = (echo "\x1B[32m>> $1\x1B[39m")
log_error = (>&2 echo "\x1B[31m>> $1\x1B[39m" && exit 1)

install:
  @[ "$(AWS_PROFILE)" ] || $(call log_error, "AWS_PROFILE not set!")
  command1  # this line will be a subshell
  command2  # this line will be another subshell
  @command3  # Use `@` to hide the command line
  $(call log_error, "It works, yey!")

uninstall:
  @[ "$(AWS_PROFILE)" ] || $(call log_error, "AWS_PROFILE not set!")
  ....
  $(call log_error, "Nuked!")

In Java you would do something similar to:

Transport transport = session.getTransport("smtps");
transport.connect (smtp_host, smtp_port, smtp_username, smtp_password);
transport.sendMessage(msg, msg.getAllRecipients());
transport.close();    

Note 'smtpS' protocol. Also socketFactory properties is no longer necessary in modern JVMs but you might need to set 'mail.smtps.auth' and 'mail.smtps.starttls.enable' to 'true' for Gmail. 'mail.smtps.debug' could be helpful too.

np.maximum not only compares elementwise but also compares array elementwise with single value

>>>np.maximum([23, 14, 16, 20, 25], 18)
array([23, 18, 18, 20, 25])

Set the CommandText as well, and call Fill on the SqlAdapter to retrieve the results in a DataSet:

var con = new SqlConnection();
con.ConnectionString = "connection string";
var com = new SqlCommand();
com.Connection = con;
com.CommandType = CommandType.StoredProcedure;
com.CommandText = "sp_returnTable";
var adapt = new SqlDataAdapter();
adapt.SelectCommand = com;
var dataset = new DataSet();
adapt.Fill(dataset);

(Example is using parameterless constructors for clarity; can be shortened by using other constructors.)

Using JQuery : http://api.jquery.com/hide/

    <li class="three">c</li>
</ul>

I figured there's no way except going into the file system to find out if text.txt is a directory or just a file. If you wanted something simple, maybe you can just use:

s.Substring(s.LastIndexOf(@"\"));

You have to tell Spring what input content-type is supported by your service. You can do this with the "consumes" Annotation Element that corresponds to your request's "Content-Type" header.

@RequestMapping(value = "/", method = RequestMethod.POST, consumes = {"application/x-www-form-urlencoded"})

It would be helpful if you posted your code.

Your code is fine. In case you're not sure how to use Calculate function, try

Calculate(5,5,(Operator)0); //this will add 5,5
Calculate(5,5,Operator.PLUS);// alternate

Default enum values start from 0 and increase by one for following elements, until you assign different values. Also you can do :

public enum Operator{PLUS=21,MINUS=345,MULTIPLY=98,DIVIDE=100};

Please be aware that the warning on iTunes Connect does not say anything about the limit being only for over-the-air delivery. It would be preferable if the warning mentioned this.

If you wish to clear your entire database.

Because of the foreign-key constraints it matters which sequence the tables are truncated. This is a way to bruteforce this sequence.

    public static void ClearDatabase<T>() where T : DbContext, new()
    {
        using (var context = new T())
        {
            var tableNames = context.Database.SqlQuery<string>("SELECT TABLE_NAME FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_TYPE = 'BASE TABLE' AND TABLE_NAME NOT LIKE '%Migration%'").ToList();
            foreach (var tableName in tableNames)
            {
                foreach (var t in tableNames)
                {
                    try
                    {

                        if (context.Database.ExecuteSqlCommand(string.Format("TRUNCATE TABLE [{0}]", tableName)) == 1)
                            break;

                    }
                    catch (Exception ex)
                    {

                    }
                }
            }

            context.SaveChanges();
        }
    }

usage:

ClearDatabase<ApplicationDbContext>();

remember to reinstantiate your DbContext after this.

You can use tf.convert_to_tensor():

import tensorflow as tf
import numpy as np

data = [[1,2,3],[4,5,6]]
data_np = np.asarray(data, np.float32)

data_tf = tf.convert_to_tensor(data_np, np.float32)

sess = tf.InteractiveSession()  
print(data_tf.eval())

sess.close()

Flying Saucer's primary purpose is to render spec-compliant XHTML and CSS 2.1 to the screen as a Swing component. Though it was originally intended for embedding markup into desktop applications (things like the iTunes Music Store), Flying Saucer has been extended work with iText as well. This makes it very easy to render XHTML to PDFs, as well as to images and to the screen. Flying Saucer requires Java 1.4 or higher.

Old question but here's the code on how to do what you are asking. In this case I am passing data from a selected cell in a table view to another view controller.

in the .h file of the trget view:

@property(weak, nonatomic)  NSObject* dataModel;

in the .m file:

@synthesize dataModel;

dataModel can be string, int, or like in this case it's a model that contains many items

- (void)someMethod {
     [self performSegueWithIdentifier:@"loginMainSegue" sender:self];
 }

OR...

- (void)someMethod {
    UIViewController *myController = [self.storyboard instantiateViewControllerWithIdentifier:@"HomeController"];
    [self.navigationController pushViewController: myController animated:YES];
}

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
    if([segue.identifier isEqualToString:@"storyDetailsSegway"]) {
        UITableViewCell *cell = (UITableViewCell *) sender;
        NSIndexPath *indexPath = [self.tableView indexPathForCell:cell];
        NSDictionary *storiesDict =[topStories objectAtIndex:[indexPath row]];
        StoryModel *storyModel = [[StoryModel alloc] init];
        storyModel = storiesDict;
        StoryDetails *controller = (StoryDetails *)segue.destinationViewController;
        controller.dataModel= storyModel;
    }
}

The problem is likely that you are calling URLEncoder.encode() on something that already is a URI.

A collection of the four seemingly most compatible methods from this page. The first one's really quite genius. Tested from XP up. Confusing though that there is no standard command available to check for admin rights. I guess they're simply focusing on PowerShell now, which is really useless for most of my own work.

I called the batch 'exit-if-not-admin.cmd' which can be called from other batches to make sure they don't continue execution if the required admin rights are not given.

C99 has it in stdbool.h, but in C90 it must be defined as a typedef or enum:

typedef int bool;
#define TRUE  1
#define FALSE 0

bool f = FALSE;
if (f) { ... }

Alternatively:

typedef enum { FALSE, TRUE } boolean;

boolean b = FALSE;
if (b) { ... }

Here's a reworking of your sample to get you started.

• your sample has a static event - it's more usual for an event to come from a class instance, but I've left it static below.

• the sample below also uses the more standard naming OnXxx for the method that raises the event.

• the sample below does not consider thread-safety, which may well be more of an issue if you insist on your event being static.

.

public enum MyEvents{ 
     Event1 
} 

public class MyEventArgs : EventArgs
{
    public MyEventArgs(MyEvents myEvents)
    {
        MyEvents = myEvents;
    }

    public MyEvents MyEvents { get; private set; }
}

public static class MyClass
{
     public static event EventHandler<MyEventArgs> EventTriggered; 

     public static void Trigger(MyEvents myEvents) 
     {
         OnMyEvent(new MyEventArgs(myEvents));
     }

     protected static void OnMyEvent(MyEventArgs e)
     {
         if (EventTriggered != null)
         {
             // Normally the first argument (sender) is "this" - but your example
             // uses a static event, so I'm passing null instead.
             // EventTriggered(this, e);
             EventTriggered(null, e);
         } 
     }
}

Tldr:

The other answers have tackled the "why" of the question. I'll provide a hack around this limitation:

The basic idea is to hijack the super statement with your embedded statements. This can be done by disguising your statements as expressions.

Tsdr:

Consider we want to do Statement1() to Statement9() before we call super():

public class Child extends Parent {
    public Child(T1 _1, T2 _2, T3 _3) {
        Statement_1();
        Statement_2();
        Statement_3(); // and etc...
        Statement_9();
        super(_1, _2, _3); // compiler rejects because this is not the first line
    }
}

The compiler will of course reject our code. So instead, we can do this:

// This compiles fine:

public class Child extends Parent {
    public Child(T1 _1, T2 _2, T3 _3) {
        super(F(_1), _2, _3);
    }

    public static T1 F(T1 _1) {
        Statement_1();
        Statement_2();
        Statement_3(); // and etc...
        Statement_9();
        return _1;
    }
}

The only limitation is that the parent class must have a constructor which takes in at least one argument so that we can sneak in our statement as an expression.

Here is a more elaborate example:

public class Child extends Parent {
    public Child(int i, String s, T1 t1) {
        i = i * 10 - 123;
        if (s.length() > i) {
            s = "This is substr s: " + s.substring(0, 5);
        } else {
            s = "Asdfg";
        }
        t1.Set(i);
        T2 t2 = t1.Get();
        t2.F();
        Object obj = Static_Class.A_Static_Method(i, s, t1);
        super(obj, i, "some argument", s, t1, t2); // compiler rejects because this is not the first line
    }
}

Reworked into:

// This compiles fine:

public class Child extends Parent {
    public Child(int i, String s, T1 t1) {
        super(Arg1(i, s, t1), Arg2(i), "some argument", Arg4(i, s), t1, Arg6(i, t1));
    }

    private static Object Arg1(int i, String s, T1 t1) {
        i = Arg2(i);
        s = Arg4(s);
        return Static_Class.A_Static_Method(i, s, t1);
    }

    private static int Arg2(int i) {
        i = i * 10 - 123;
        return i;
    }

    private static String Arg4(int i, String s) {
        i = Arg2(i);
        if (s.length() > i) {
            s = "This is sub s: " + s.substring(0, 5);
        } else {
            s = "Asdfg";
        }
        return s;
    }

    private static T2 Arg6(int i, T1 t1) {
        i = Arg2(i);
        t1.Set(i);
        T2 t2 = t1.Get();
        t2.F();
        return t2;
    }
}

In fact, compilers could have automated this process for us. They'd just chosen not to.

Or run a pip install --upgrade pip enum34

Please check with this documentation.

http://php.net/manual/en/function.error-log.php

Example:

<?php
// Send notification through the server log if we can not
// connect to the database.
if (!Ora_Logon($username, $password)) {
    error_log("Oracle database not available!", 0);
}

// Notify administrator by email if we run out of FOO
if (!($foo = allocate_new_foo())) {
    error_log("Big trouble, we're all out of FOOs!", 1,
               "[email protected]");
}

// another way to call error_log():
error_log("You messed up!", 3, "/var/tmp/my-errors.log");
?>

var classes = $('html')[0].className;

if (classes.indexOf('m320') != -1 || classes.indexOf('m768') != -1) {
    //do something
}

Create a class and give it an __init__ method:

class Student:
    def __init__(self, name, age, major):
        self.name = name
        self.age = age
        self.major = major

    def is_old(self):
        return self.age > 100

Now, you can initialize an instance of the Student class:

>>> s = Student('John', 88, None)
>>> s.name
    'John'
>>> s.age
    88

Although I'm not sure why you need a make_student student function if it does the same thing as Student.__init__.

If you have installed GitHubDesktop in Windows 10, then press Ctrl + '. or in the menu go to Repository>Open in command prompt.

In case git is not installed in your machine, you should get a prompt to install git.(I came to know from this that GitHubDesktop and git are different applications). Install git, close your command prompt and open it again.

You can test your installation by typing in git at the command prompt.

i used this code to change status bar to transparent

    activity?.window?.setFlags(
        WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS,
        WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS
    )

to change it to color in style used this code i used in fragment in onDetach()

activity?.window?.clearFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS)

another workaround:

var myarray = [];
$("#test").click(function() {
    myarray[index]=$("#drop").val();
    alert(myarray);
});

i wanted to add all checked checkbox to array. so example, if .each is used:

var vpp = [];
var incr=0;
$('.prsn').each(function(idx) {
   if (this.checked) {
       var p=$('.pp').eq(idx).val();
       vpp[incr]=(p);
       incr++;
   }
});
//do what ever with vpp array;

set "CMD=C:\Program Files (x86)\PDFtk\bin\pdftk"
echo cmd /K ""%CMD%" %D% output trimmed.pdf"
start cmd /K ""%CMD%" %D% output trimmed.pdf"

this worked for me in a batch file

=>Create a new table directly with the following query:

CREATE TABLE table_name (Column_1 TEXT,Column_2 TEXT);

=>Now insert the data into table_name from existing_table with the following query:

INSERT INTO table_name (Column_1,Column_2) FROM existing_table;

=>Now drop the existing_table by following query:

DROP TABLE existing_table;

In my case I am restoring a SQL Server 2008 R2 Database to SQL Server 2016 After selecting the file in the General tab, you should go to the Options tab and do 2 things:

1. You must activate Overwrite existing database
2. You must deactivate end of record copy

but it ONLY shows the index.html file and NOTHING attached to it, so no images, no effects or anything that the html file should display.

That's because in your program that's the only thing that you return to the browser regardless of what the request looks like.

You can take a look at a more complete example that will return the correct files for the most common web pages (HTML, JPG, CSS, JS) in here https://gist.github.com/hectorcorrea/2573391

Also, take a look at this blog post that I wrote on how to get started with node. I think it might clarify a few things for you: http://hectorcorrea.com/blog/introduction-to-node-js

Try using os.makedirs:

import os
import errno

try:
    os.makedirs(<path>)
except OSError as e:
    if errno.EEXIST != e.errno:
        raise

You could do it this way but it leaves it as a varchar

declare @s varchar(50)

set @s = '2011-09-28 18:01:00'

select convert(varchar, cast(@s as datetime), 105) + RIGHT(@s, 9)

or

select convert(varchar(20), @s, 105)

If you don't want to clutter up your console with error messages, you can also run

git ls-files file_name

and then check the result. If git returns nothing, then the file is not tracked. If it's tracked, git will return the file path.

This comes in handy if you want to combine it in a script, for example PowerShell:

$gitResult = (git ls-files $_) | out-string
if ($gitResult.length -ne 0)
{
    ## do stuff with the tracked file
}

Try serialize(). It converts an array into a string format, you can then use unserialize() to convert it back to an array. Scripts like WordPress use this to save multiple values to a single database field.

You can also use json_encode() as Rob said, which maybe useful if you want to read the cookie in javascript.

If there is XML file with 2 different tables then will:

LOAD XML LOCAL INFILE 'table1.xml' INTO TABLE table1 
LOAD XML LOCAL INFILE 'table1.xml' INTO TABLE table2

work

480 dpi is the standard QUANTIZED resolution for xxhdpi, it can vary something less (i.e.: 440 dpi) or more (i.e.: 520 dpi). Scale factor: 3x (3 * mdpi).

Now there's a higher resolution, xxxhdpi (640 dpi). Scale factor 4x (4 * mdpi).

Here's the source reference.

If you are using Multidex on Android 4.4 and prior, your issue might be that your activity class is located in the second dex file and therefore not found by the android system.

To keep your activity class in the main dex file, see this page:

https://developer.android.com/studio/build/multidex.html#keep

To find which classes are located in a dex file use Android Studio.

Simply drag n drop your apk into Android Studio. You should be able to see your dex files in the apk explorer.

Then select the dex file to see what classes are inside.

another alternative is dexdump:

You can check the content of your dex files contained in your apk by using the command dexdump which can be found in

android-sdk/build-tools/27.0.3/dexdump

For windows users see this tool I made to ease the process

The 1s are because everything is perfectly correlated with itself, and the NAs are because there are NAs in your variables.

You will have to specify how you want R to compute the correlation when there are missing values, because the default is to only compute a coefficient with complete information.

You can change this behavior with the use argument to cor, see ?cor for details.

I think the answer of Curt is correct, however, what if you want to add a class to a div that already has a class declared in the ASP.NET code.

Here is my solution for that, it is a generic method so you can call it directly as this:

Asp Net Div declaration:

<div id="divButtonWrapper" runat="server" class="text-center smallbutton fixPad">

Code to add class:

divButtonWrapper.AddClassToHtmlControl("nameOfYourCssClass")

Generic class:

public static class HtmlGenericControlExtensions
{
    public static void AddClassToHtmlControl(this HtmlGenericControl htmlGenericControl, string className)
    {
        if (string.IsNullOrWhiteSpace(className))
            return;

        htmlGenericControl
            .Attributes.Add("class", string.Join(" ", htmlGenericControl
            .Attributes["class"]
            .Split(' ')
            .Except(new[] { "", className })
            .Concat(new[] { className })
            .ToArray()));
    }
}

I solved the same problem by adding text-indent to the nested list.

<h4>A nested List:</h4>
<ul>
  <li>Coffee</li>
  <li>Tea
    <ul id="list2">
    <li>Black tea</li>
    <li>Green tea</li>
    </ul>
  </li>
  <li>Milk</li>
</ul>

#list2
{
 text-indent:50px;
}

You could sort the array first (Ascending by default) and then apply np.flip() (https://docs.scipy.org/doc/numpy/reference/generated/numpy.flip.html)

FYI It works with datetime objects as well.

Example:

    x = np.array([2,3,1,0]) 
    x_sort_asc=np.sort(x) 
    print(x_sort_asc)

    >>> array([0, 1, 2, 3])

    x_sort_desc=np.flip(x_sort_asc) 
    print(x_sort_desc)

    >>> array([3,2,1,0])

e.printStackTrace equivalent in python

In Java, this does the following (docs):

public void printStackTrace()

Prints this throwable and its backtrace to the standard error stream...

This is used like this:

try
{ 
// code that may raise an error
}
catch (IOException e)
{
// exception handling
e.printStackTrace();
}

In Java, the Standard Error stream is unbuffered so that output arrives immediately.

The same semantics in Python 2 are:

import traceback
import sys
try: # code that may raise an error
    pass 
except IOError as e: # exception handling
    # in Python 2, stderr is also unbuffered
    print >> sys.stderr, traceback.format_exc()
    # in Python 2, you can also from __future__ import print_function
    print(traceback.format_exc(), file=sys.stderr)
    # or as the top answer here demonstrates, use:
    traceback.print_exc()
    # which also uses stderr.

Python 3

In Python 3, we can get the traceback directly from the exception object (which likely behaves better for threaded code). Also, stderr is line-buffered, but the print function gets a flush argument, so this would be immediately printed to stderr:

    print(traceback.format_exception(None, # <- type(e) by docs, but ignored 
                                     e, e.__traceback__),
          file=sys.stderr, flush=True)

Conclusion:

In Python 3, therefore, traceback.print_exc(), although it uses sys.stderr by default, would buffer the output, and you may possibly lose it. So to get as equivalent semantics as possible, in Python 3, use print with flush=True.

This is what a constant expression in Java looks like:

package com.mycompany.mypackage;

public class MyLinks {
  // constant expression
  public static final String GUESTBOOK_URL = "/guestbook";
}

You can use it with annotations as following:

import com.mycompany.mypackage.MyLinks;

@WebServlet(urlPatterns = {MyLinks.GUESTBOOK_URL})
public class GuestbookServlet extends HttpServlet {
  // ...
}

interface supports Python 2.7 and Python 3.4+.

To install interface you have to

pip install python-interface

Example Code:

from interface import implements, Interface

class MyInterface(Interface):

    def method1(self, x):
        pass

    def method2(self, x, y):
        pass


class MyClass(implements(MyInterface)):

    def method1(self, x):
        return x * 2

    def method2(self, x, y):
        return x + y

There's now a UITextField delegate method available on iOS13+

optional func textFieldDidChangeSelection(_ textField: UITextField)

Suppose you want to add those flags (better to declare them in a constant):

SET(GCC_COVERAGE_COMPILE_FLAGS "-fprofile-arcs -ftest-coverage")
SET(GCC_COVERAGE_LINK_FLAGS    "-lgcov")

There are several ways to add them:

1. The easiest one (not clean, but easy and convenient, and works only for compile flags, C & C++ at once):

   add_definitions(${GCC_COVERAGE_COMPILE_FLAGS})
   

2. Appending to corresponding CMake variables:

   SET(CMAKE_CXX_FLAGS  "${CMAKE_CXX_FLAGS} ${GCC_COVERAGE_COMPILE_FLAGS}")
   SET(CMAKE_EXE_LINKER_FLAGS  "${CMAKE_EXE_LINKER_FLAGS} ${GCC_COVERAGE_LINK_FLAGS}")
   

3. Using target properties, cf. doc CMake compile flag target property and need to know the target name.

   get_target_property(TEMP ${THE_TARGET} COMPILE_FLAGS)
   if(TEMP STREQUAL "TEMP-NOTFOUND")
     SET(TEMP "") # Set to empty string
   else()
     SET(TEMP "${TEMP} ") # A space to cleanly separate from existing content
   endif()
   # Append our values
   SET(TEMP "${TEMP}${GCC_COVERAGE_COMPILE_FLAGS}" )
   set_target_properties(${THE_TARGET} PROPERTIES COMPILE_FLAGS ${TEMP} )
   

Right now I use method 2.

select * from table where column_date > now()- INTERVAL '6 hours';

Complement with an additional example, you can access all job parameters in JavaConfig class:

@Bean
@StepScope
public ItemStreamReader<GenericMessage> reader(@Value("#{jobParameters}") Map<String,Object> jobParameters){
          ....
}

Another option which is more suitable for debugging but worth mentioning is to check in revision history of your rollout:

$ kubectl rollout history deployment my-dep
deployment.apps/my-dep
 
REVISION  CHANGE-CAUSE
1         <none>
2         <none>
3         <none>

To see the details of each revision, run:

 kubectl rollout history deployment my-dep --revision=2

And then returning to the previous revision by running:

 $kubectl rollout undo deployment my-dep --to-revision=2

And then returning back to the new one.
Like running ctrl+z -> ctrl+y (:

(*) The CHANGE-CAUSE is <none> because you should run the updates with the --record flag - like mentioned here:

kubectl set image deployment/nginx-deployment nginx=nginx:1.16.1 --record

(**) There is a discussion regarding deprecating this flag.

Use:

Set-ExecutionPolicy -ExecutionPolicy Bypass -Scope Process

Always use the above command to enable to executing PowerShell in the current session.

Enter the submodule directory:

cd projB/projA

Pull the repo from you project A (will not update the git status of your parent, project B):

git pull origin master

Go back to the root directory & check update:

cd ..
git status

If the submodule updated before, it will show something like below:

# Not currently on any branch.
# Changed but not updated:
#   (use "git add ..." to update what will be committed)
#   (use "git checkout -- ..." to discard changes in working directory)
#
#       modified:   projB/projA (new commits)
#

Then, commit the update:

git add projB/projA
git commit -m "projA submodule updated"

UPDATE

As @paul pointed out, since git 1.8, we can use

git submodule update --remote --merge

to update the submodule to the latest remote commit. It'll be convenient in most cases.

Working with atom (1.21.1 ia32)... i got the same error, even though i added a reference to my pipe in the app.module.ts and in the declarations within app.module.ts

This is not as easy as it seems, some core library functions don't work when only str is overwritten (checked with Python 2.7), see this thread for examples How to make a class JSON serializable Also, try this

import json

class A(unicode):
    def __str__(self):
        return 'a'
    def __unicode__(self):
        return u'a'
    def __repr__(self):
        return 'a'

a = A()
json.dumps(a)

produces

'""'

and not

'"a"'

as would be expected.

EDIT: answering mchicago's comment:

unicode does not have any attributes -- it is an immutable string, the value of which is hidden and not available from high-level Python code. The json module uses re for generating the string representation which seems to have access to this internal attribute. Here's a simple example to justify this:

b = A('b') print b

produces

'a'

while

json.dumps({'b': b})

produces

{"b": "b"}

so you see that the internal representation is used by some native libraries, probably for performance reasons.

I've been using this because I'm returning results from another table. Though I'm trying to avoid the nested join if it helps w/ one less step. Oh well. It returns the same thing.

select
users.userid
, lastIP.IP
, lastIP.maxdate

from users

inner join (
    select userid, IP, datetime
    from IPAddresses
    inner join (
        select userid, max(datetime) as maxdate
        from IPAddresses
        group by userid
        ) maxIP on IPAddresses.datetime = maxIP.maxdate and IPAddresses.userid = maxIP.userid
    ) as lastIP on users.userid = lastIP.userid

$crud->set_relation('id','students','{first_name} {last_name}');
$crud->display_as('student_id','Students Name');

// 2. Select a database to use 
$db_select = mysqli_select_db($connection, DB_NAME);
if (!$db_select) {
    die("Database selection failed: " . mysqli_error($connection));
}

You got the order of the arguments to mysqli_select_db() backwards. And mysqli_error() requires you to provide a connection argument. mysqli_XXX is not like mysql_XXX, these arguments are no longer optional.

Note also that with mysqli you can specify the DB in mysqli_connect():

$connection = mysqli_connect(DB_SERVER, DB_USER, DB_PASS, DB_NAME);
if (!$connection) {
  die("Database connection failed: " . mysqli_connect_error();
}

You must use mysqli_connect_error(), not mysqli_error(), to get the error from mysqli_connect(), since the latter requires you to supply a valid connection.

The following should work with the latest version of Apache common codec

byte[] decodedBytes = Base64.getDecoder().decode("YWJjZGVmZw==");
System.out.println(new String(decodedBytes));

and for encoding

byte[] encodedBytes = Base64.getEncoder().encode(decodedBytes);
System.out.println(new String(encodedBytes));

there is a JDK tools executed via command line as following :

native2ascii -encoding utf8 src.txt output.txt

Example :

src.txt

??? ???? ?????? ??????

output.txt

\u0628\u0633\u0645 \u0627\u0644\u0644\u0647 \u0627\u0644\u0631\u062d\u0645\u0646 \u0627\u0644\u0631\u062d\u064a\u0645

If you want to use it in your Java application, you can wrap this command line by :

String pathSrc = "./tmp/src.txt";
String pathOut = "./tmp/output.txt";
String cmdLine = "native2ascii -encoding utf8 " + new File(pathSrc).getAbsolutePath() + " " + new File(pathOut).getAbsolutePath();
Runtime.getRuntime().exec(cmdLine);
System.out.println("THE END");

Then read content of the new file.

Here's how you can POST XML on Windows using curl command line on Windows. Better use batch/.cmd file for that:

curl -i -X POST -H "Content-Type: text/xml" -d             ^

fields() and fieldNames() both were not working for me. And I had to spend quite sometime to find a way to iterate over the keys. There are two ways by which it can be done.

One is by converting it into a map (takes up more space):

ObjectMapper mapper = new ObjectMapper();
Map<String, Object> result = mapper.convertValue(jsonNode, Map.class);
for (String key : result.keySet())
{
    if(key.equals(foo))
    {
        //code here
    }
}

Another, by using a String iterator:

Iterator<String> it = jsonNode.getFieldNames();
while (it.hasNext())
{
    String key = it.next();
    if (key.equals(foo))
    {
         //code here
    }
}

You should really rethink your approach to this issue. Using a well crafted selector and attaching the class may be a more elegant solution to this approach. As far as I know you cannot modify external CSS.

In the System.Windows.Forms class, you can find more on the MSDN page for this here. Among other things you can control the message box text, title, default button, and icons. Since you didn't specify, if you are trying to do this in a webpage you should look at triggering the javascript alert("my message"); or confirm("my question"); functions.

To solve this problem (RPC:S-5:AEC-0):

1. Go to settings
2. Go to backup and reset
3. Go down to recovery mode
4. Reboot the system

This seemed to fix the problem for my tab. Now I can use Google Play store and download any app I want.

A simple workaround is to use a iframe to hold the "nested" form. Visually the form is nested but on the code side its in a separate html file altogether.

To diagnose this issue, place the line of code causing the TargetInvocationException inside the try block.

To troubleshoot this type of error, get the inner exception. It could be due to a number of different issues.

try
{
    // code causing TargetInvocationException
}
catch (Exception e)
{
    if (e.InnerException != null)
    {
    string err = e.InnerException.Message;
    }
}

To add to MattDMo's answer, you can get the exact font that's used on Linux like so (the example is from Xubuntu 14.04):

$ fc-match Monospace
DejaVuSansMono.ttf: "DejaVu Sans Mono" "Book"

As I can't comment yet, I want to show the solution I used based on the method Umair Ahmed posted, but when you want to search for a key instead of a value:

[{"a":true}, {"f":true}, {"g":false}]
.findIndex(function(element){return Object.keys(element)[0] == "g"});

I understand that it doesn't answer the expanded question, but the title doesn't specify what was wanted from each object, so I want to humbly share this to save headaches to others in the future, while I undestart it may not be the fastest solution.

a null string is null, an empty string is ""

isNullOrEmpty requires an intimate understanding about the implementation of a string. If you want one, you can write one yourself for your object, but you have to make your own definition for whether your object is "empty" or not.

ask yourself: What does it mean for an object to be empty?

tree -L 2 -u -g -p -d

Prints the directory tree in a pretty format up to depth 2 (-L 2). Print user (-u) and group (-g) and permissions (-p). Print only directories (-d). tree has a lot of other useful options.

If I'm correct in thinking that you want to find the minimum value of a function for all possible pairs of 2 elements from a list...

l = [1,2,3,4,5]

def f(i,j):
   return i+j 

# Prints min value of f(i,j) along with i and j
print min( (f(i,j),i,j) for i in l for j in l)

If you want, you can use the "define" function, but this function creates a constant which can't be changed once defined.

<?php
    define("GREETING", "Welcome to W3Schools.com!");

    function myTest() {
        echo GREETING;
    }

    myTest();
?>

PHP Constants

Abstract classes and interfaces are semantically different, although their usage can overlap.

An abstract class is generally used as a building basis for similar classes. Implementation that is common for the classes can be in the abstract class.

An interface is generally used to specify an ability for classes, where the classes doesn't have to be very similar.

If you just need to print present working directory then you can follow this.

$ vim test

#!/bin/bash
pwd
:wq to save the test file.

Give execute permission:

chmod u+x test

Then execute the script by ./test then you can see the present working directory.

Faster way of writing it would be...

in = open('path/to/input/file').read()
out = open('path/to/input/file', 'w')
replacements = {'zero':'0', 'temp':'bob', 'garbage':'nothing'}
for i in replacements.keys():
    in = in.replace(i, replacements[i])
out.write(in)
out.close

This eliminated a lot of the iterations that the other answers suggest, and will speed up the process for longer files.

Unless you need to be able to change the deleter at runtime, I would strongly recommend using a custom deleter type. For example, if use a function pointer for your deleter, sizeof(unique_ptr<T, fptr>) == 2 * sizeof(T*). In other words, half of the bytes of the unique_ptr object are wasted.

Writing a custom deleter to wrap every function is a bother, though. Thankfully, we can write a type templated on the function:

Since C++17:

template <auto fn>
using deleter_from_fn = std::integral_constant<decltype(fn), fn>;

template <typename T, auto fn>
using my_unique_ptr = std::unique_ptr<T, deleter_from_fn<fn>>;

// usage:
my_unique_ptr<Bar, destroy> p{create()};

Prior to C++17:

template <typename D, D fn>
using deleter_from_fn = std::integral_constant<D, fn>;

template <typename T, typename D, D fn>
using my_unique_ptr = std::unique_ptr<T, deleter_from_fn<D, fn>>;

// usage:
my_unique_ptr<Bar, decltype(destroy), destroy> p{create()};

ToString can take a format. try:

i.ToString("000");

Let's say we are trying to find the square root of 2, and you have an estimate of 1.5. We'll say a = 2, and x = 1.5. To compute a better estimate, we'll divide a by x. This gives a new value y = 1.333333. However, we can't just take this as our next estimate (why not?). We need to average it with the previous estimate. So our next estimate, xx will be (x + y) / 2, or 1.416666.

Double squareRoot(Double a, Double epsilon) {
    Double x = 0d;
    Double y = a;
    Double xx = 0d;

    // Make sure both x and y != 0.
    while ((x != 0d || y != 0d) && y - x > epsilon) {
        xx = (x + y) / 2;

        if (xx * xx >= a) {
            y = xx;
        } else {
            x = xx;
        }
    }

    return xx;
}

Epsilon determines how accurate the approximation needs to be. The function should return the first approximation x it obtains that satisfies abs(x*x - a) < epsilon, where abs(x) is the absolute value of x.

square_root(2, 1e-6)
Output: 1.4142141342163086

Another difference is that <import> allows importing by referring to another namespace. <include> only allows importing by referring to a URI of intended include schema. That is definitely another difference than inter-intra namespace importing.

For example, the xml schema validator may already know the locations of all schemas by namespace already. Especially considering that referring to XML namespaces by URI may be problematic on different systems where classpath:// means nothing, or where http:// isn't allowed, or where some URI doesn't point to the same thing as it does on another system.

Code sample of valid and invalid imports and includes:

Valid:

<xsd:import namespace="some/name/space"/>
<xsd:import schemaLocation="classpath://mine.xsd"/>

<xsd:include schemaLocation="classpath://mine.xsd"/>

Invalid:

<xsd:include namespace="some/name/space"/>

To check if a string variable contains a valid email address, the easiest way is to test it against a regular expression. There is a good discussion of various regex's and their trade-offs at regular-expressions.info.

Here is a relatively simple one that leans on the side of allowing some invalid addresses through: ^[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,6}$

How you can use regular expressions depends on the version of iOS you are using.

iOS 4.x and Later

You can use NSRegularExpression, which allows you to compile and test against a regular expression directly.

iOS 3.x

Does not include the NSRegularExpression class, but does include NSPredicate, which can match against regular expressions.

NSString *emailRegex = ...;
NSPredicate *emailTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", emailRegex];
BOOL isValid = [emailTest evaluateWithObject:checkString];

Read a full article about this approach at cocoawithlove.com.

iOS 2.x

Does not include any regular expression matching in the Cocoa libraries. However, you can easily include RegexKit Lite in your project, which gives you access to the C-level regex APIs included on iOS 2.0.

If you want to override standard href-id navigation on the page without changing the HTML markup for smooth scrolling, use this (example):

// handle links with @href started with '#' only
$(document).on('click', 'a[href^="#"]', function(e) {
    // target element id
    var id = $(this).attr('href');

    // target element
    var $id = $(id);
    if ($id.length === 0) {
        return;
    }

    // prevent standard hash navigation (avoid blinking in IE)
    e.preventDefault();

    // top position relative to the document
    var pos = $id.offset().top;

    // animated top scrolling
    $('body, html').animate({scrollTop: pos});
});

Input: C:\path\Filename.ext
Output: Filename

In HTML code, set the File onChange value like this...

<input type="file" name="formdata" id="formdata" onchange="setfilename(this.value)"/>

    filename = val.split('\\').pop().split('/').pop();
    filename = filename.substring(0, filename.lastIndexOf('.'));

• JDK - Java Development Kit
• JRE - Java Runtime Environment
• Java SE - Java Standard Edition

SE defines a set of capabilities and functionalities; there are more complex editions (Enterprise Edition – EE) and simpler ones (Micro Edition – ME – for mobile environments).

The JDK includes the compiler and other tools needed to develop Java applications; JRE does not. So, to run a Java application someone else provides, you need JRE; to develop a Java application, you need JDK.

Edited: As Chris Marasti-Georg pointed out in a comment, you can find out lots of information at Sun's Java web site, and in particular from the Java SE section, (2nd option, Java SE Development Kit (JDK) 6 Update 10).

Edited 2011-04-06: The world turns, and Java is now managed by Oracle, which bought Sun. Later this year, the sun.com domain is supposed to go dark. The new page (based on a redirect) is this Java page at the Oracle Tech Network. (See also java.com.)

Edited 2013-01-11: And the world keeps on turning (2012-12-21 notwithstanding), and lo and behold, JRE 6 is about to reach its end of support. Oracle says no more public updates to Java 6 after February 2013.

Within a given version of Java, this answer remains valid. JDK is the Java Development Kit, JRE is the Java Runtime Environment, Java SE is the standard edition, and so on. But the version 6 (1.6) is becoming antiquated.

Edited 2015-04-29: And with another couple of revolutions around the sun, the time has come for the end of support for Java SE 7, too. In April 2015, Oracle affirmed that it was no longer providing public updates to Java SE 7. The tentative end of public updates for Java SE 8 is March 2017, but that end date is subject to change (later, not earlier).

Been using this in production for some time now without any complaints (May take some tweaking to look right on your site.. for instance, subtracting the width of a sidebar, etc)

$(window).bind('resize', function() {
    $("#jqgrid").setGridWidth($(window).width());
}).trigger('resize');

In my case, I had to run journalctl -xe, and it showed that my disk was full. I then deleted some .gz items from /var/log and I could again restart the postgresql.

From the CLI the best way is to use grep like:

php -i | grep libxml

Unusual filenames (such as a file containing the valid \n character can wreak havoc with this kind of parsing. Here's a way to do it in Perl:

perl -le '@sorted = map {$_->[0]} 
                    sort {$a->[1] <=> $b->[1]} 
                    map {[$_, -M $_]} 
                    @ARGV;
          print $sorted[0]
' b2*

That's a Schwartzian transform used there.

In order for IIS Express answer on any IP address, just leave the address blank, i.e:

bindingInformation=":8080:"

Don't forget to restart the IIS express before the changes can take place.

If, after reading the other questions and viewing the links mentioned in the comment sections, you still can't figure it out, read on.

First of all, where you're going wrong is the offset.

It should look more like this...

set mydate=%date:~10,4%%date:~6,2%/%date:~4,2%
echo %mydate%

If the date was Tue 12/02/2013 then it would display it as 2013/02/12.

To remove the slashes, the code would look more like

set mydate=%date:~10,4%%date:~7,2%%date:~4,2%
echo %mydate%

which would output 20130212

And a hint for doing it in the future, if mydate equals something like %date:~10,4%%date:~7,2% or the like, you probably forgot a tilde (~).
