This is an interesting question, i just want to give another angle by adding a little more info.You can understand why an exception is thrown if you see how static methods operate. These methods can manipulate either static data, local data or data that is sent to it as a parameter.why? because static method can be accessed by any object, from anywhere. So, there can be security issues posed or there can be leaks of information if it can use instance variables.Hence the compiler has to throw such a case out of consideration.

jdbc:jtds:sqlserver://x.x.x.x/database replacing x.x.x.x with the IP or hostname of your SQL Server machine.

jdbc:jtds:sqlserver://MYPC/Blog;instance=SQLEXPRESS

or

jdbc:jtds:sqlserver://MYPC:1433/Blog;instance=SQLEXPRESS

If you are wanting to set the username and password in the connection string too instead of against a connection object separately:

jdbc:jtds:sqlserver://MYPC/Blog;instance=SQLEXPRESS;user=foo;password=bar

(Updated my incorrect information and add reference to the instance syntax)

With all the solutions above even though you're hiding the code, you'll still get the [<matplotlib.lines.Line2D at 0x128514278>] crap above your figure which you probably don't want.

If you actually want to get rid of the input rather than just hiding it, I think the cleanest solution is to save your figures to disk in hidden cells, and then just including the images in Markdown cells using e.g. ![Caption](figure1.png).

Try to encapsulate the ajax call into a function and set the async option to false. Note that this option is deprecated since jQuery 1.8.

function foo() {
    var myajax = $.ajax({
        type: "POST",
        url: "CHService.asmx/SavePurpose",
        dataType: "text",
        data: JSON.stringify({ Vid: Vid, PurpId: PurId }),
        contentType: "application/json; charset=utf-8",
        async: false, //add this
    });
    return myajax.responseText;
}

You can do this also:

$.ajax({
    type: "POST",
    url: "CHService.asmx/SavePurpose",
    dataType: "text",
    data: JSON.stringify({ Vid: Vid, PurpId: PurId }),
    contentType: "application/json; charset=utf-8",
    async: false, //add this
}).done(function ( data ) {
        Success = true;
}).fail(function ( data ) {
       Success = false;
});

both results will same....

When you call a function, a new "namespace" is allocated on the stack. That's how functions can have local variables. As functions call functions, which in turn call functions, we keep allocating more and more space on the stack to maintain this deep hierarchy of namespaces.

To curb programs using massive amounts of stack space, a limit is usually put in place via ulimit -s. If we remove that limit via ulimit -s unlimited, our programs will be able to keep gobbling up RAM for their evergrowing stack until eventually the system runs out of memory entirely.

int eat_stack_space(void) { return eat_stack_space(); }
// If we compile this with no optimization and run it, our computer could crash.

Usually, using a ton of stack space is accidental or a symptom of very deep recursion that probably should not be relying so much on the stack. Thus the stack limit.

Impact on performace is minor but does exist. Using the time command, I found that eliminating the stack limit increased performance by a few fractions of a second (at least on 64bit Ubuntu).

if just everything could be this simple...

Also, I noticed one more difference between .load and .ready. I am opening a child window and I am performing some work when child window opens. .load is called only first time when I open the window and if I don't close the window then .load will not be called again. however, .ready is called every time irrespective of close the child window or not.

If you are using six, you can try this, by which utilizing the latest Python 3 API and can run in both Python 2/3:

import six

if six.PY2:
    # FileNotFoundError is only available since Python 3.3
    FileNotFoundError = IOError
    from io import open

fname = 'index.rst'
try:
    with open(fname, "rt", encoding="utf-8") as f:
        pass
        # do_something_with_f ...
except FileNotFoundError:
    print('Oops.')

And, Python 2 support abandon is just deleting everything related to six.

You are missing the selector in the .on function:

Renaming the .exe and .pub file worked for me, but really tedious. I also face the problem that I could not do editing during a debug session. Finally I went to the Advanced Security Setting Page, as per:

https://msdn.microsoft.com/query/dev10.query?appId=Dev10IDEF1&l=EN-US&k=k%28%22VS.ERR.DEBUG_IN_ZONE_NO_HOSTPROC%3a11310%22%29;k%28TargetFrameworkMoniker-%22.NETFRAMEWORK%2cVERSION%3dV4.0%22%29&rd=true

I un-select then re-select the "Enable ClickOnce security settings" checkbox. It's been problem free for some days now....

x.transpose[6][3..8] or x[3..8].map {|r| r [6]} would give what you want.

Example:

a = [ [1,  2,  3,  4,  5],
      [6,  7,  8,  9,  10],
      [11, 12, 13, 14, 15],
      [21, 22, 23, 24, 25]
    ]

#a[1..2][2]  -> [8,13]
puts a.transpose[2][1..2].inspect   # [8,13]
puts a[1..2].map {|r| r[2]}.inspect  # [8,13]

Kalle posted a link to a page that has this video on it, but it's done on XP. If you use Windows 7:

1. Press the windows key.
2. Type "system env". Press enter.
3. Press alt + n
4. Press alt + e
5. Press right, and then ; (that's a semicolon)
6. Without adding a space, type this at the end: C:\Python27
7. Hit enter twice. Hit esc.
8. Use windows key + r to bring up the run dialog. Type in python and press enter.

To delete data from the tables having relationship of parent_child, First you have to delete the data from the child table by mentioning join then simply delete the data from the parent table, example is given below:

DELETE ChildTable
FROM ChildTable inner join ChildTable on PParentTable.ID=ChildTable.ParentTableID
WHERE <WHERE CONDITION> 


DELETE  ParentTable
WHERE <WHERE CONDITION>

With most Awk implementations:

awk 'BEGIN {srand(); print srand()}'

map.keySet()

will return you all the keys. If you want the keys to be sorted, you might consider a TreeMap

I landed on this question because I needed to attach an Excel file I generate through code and is available as MemoryStream. I could attach it to the mail message but it was sent as 64Bytes file instead of a ~6KB as it was meant. So, the solution that worked for me was this:

MailMessage mailMessage = new MailMessage();
Attachment attachment = new Attachment(myMemorySteam, new ContentType(MediaTypeNames.Application.Octet));

attachment.ContentDisposition.FileName = "myFile.xlsx";
attachment.ContentDisposition.Size = attachment.Length;

mailMessage.Attachments.Add(attachment);

Setting the value of attachment.ContentDisposition.Size let me send messages with the correct size of attachment.

Thank you, Erik, for posting this. This worked for me. I'd like to add a note about an extra step I needed. Within "Payload/Application.app/" there was a directory named "CACertChains" that contained a file named "cacert.pem". I had to remove the directory and the .pem to complete these steps.

Install file loader first:

$ npm install file-loader --save-dev

And add this rule in webpack.config.js

           {
                test: /\.(png|jpg|gif)$/,
                use: [{
                    loader: 'file-loader',
                    options: {}
                }]
            }

If you run it, it will work, but in order for SQL Developer to recognize and not warn about a possible error you can change it as:

Just store the index generated in a variable, and then access the array using this varaible:

int idx = new Random().nextInt(fruits.length);
String random = (fruits[idx]);

P.S. I usually don't like generating new Random object per randoization - I prefer using a single Random in the program - and re-use it. It allows me to easily reproduce a problematic sequence if I later find any bug in the program.

According to this approach, I will have some variable Random r somewhere, and I will just use:

int idx = r.nextInt(fruits.length)

However, your approach is OK as well, but you might have hard time reproducing a specific sequence if you need to later on.

Using table-layout: fixed as a property for table and width: calc(100%/3); for td (assuming there are 3 td's). With these two properties set, the table cells will be equal in size.

How about subclassing json.JSONEncoder?

class DecimalEncoder(json.JSONEncoder):
    def default(self, o):
        if isinstance(o, decimal.Decimal):
            # wanted a simple yield str(o) in the next line,
            # but that would mean a yield on the line with super(...),
            # which wouldn't work (see my comment below), so...
            return (str(o) for o in [o])
        return super(DecimalEncoder, self).default(o)

Then use it like so:

json.dumps({'x': decimal.Decimal('5.5')}, cls=DecimalEncoder)

if you are a exists project, maybe should execute npm install.

guntjs getting started step 2.

What do you mean by a long date type?

You can cast a long to a double:

double d = (double) 15552451L;

if (!$('#singlechatpanel-1').css('display') == 'none') {
   alert('visible');
}else{
   alert('hidden');
}

any of these should work

outf.write("%s" % num)

outf.write(str(num))

print >> outf, num

The mipmap folders are for placing your app/launcher icons (which are shown on the homescreen) in only. Any other drawable assets you use should be placed in the relevant drawable folders as before.

According to this Google blogpost:

It’s best practice to place your app icons in mipmap- folders (not the drawable- folders) because they are used at resolutions different from the device’s current density.

When referencing the mipmap- folders ensure you are using the following reference:

android:icon="@mipmap/ic_launcher"

The reason they use a different density is that some launchers actually display the icons larger than they were intended. Because of this, they use the next size up.

Also are supported HTML5 hashchange event and ononline, offline event

You don't need to own a Mac nor do you need to learn Objective-C. You can develop in different environments and compile into Objective-C later on.

developing for the iphone and ipad by runing osx 10.6(snow leopard)

This article one of our developers wrote gives a pretty comprehensive walk through on installing OS X Snow Leopard on Windows using iBoot, then installing Vmware (with instructions), then getting your iPhone dev environment going... and a few extra juicy things. Super helpful for me.

Hope that helps. It uses Phonegap so you can develop on multiple smart phone platforms at once.

In SQL, I would have do it in one shot as

update table1 set col1 = new_value where col1 = old_value

but in Python Pandas, we could just do this:

data = [['ram', 10], ['sam', 15], ['tam', 15]] 
kids = pd.DataFrame(data, columns = ['Name', 'Age']) 
kids

which will generate the following output :

    Name    Age
0   ram     10
1   sam     15
2   tam     15

now we can run:

kids.loc[kids.Age == 15,'Age'] = 17
kids

which will show the following output

Name    Age
0   ram     10
1   sam     17
2   tam     17

which should be equivalent to the following SQL

update kids set age = 17 where age = 15

Try adding display: table-cell; width: 1%; to your table cell element.

.table-cell {_x000D_
  display: table-cell;_x000D_
  width: 1%;_x000D_
  padding: 4px;_x000D_
  border: 1px solid #efefef;_x000D_
}

<div class="table">_x000D_
  <div class="table-cell">one</div>_x000D_
  <div class="table-cell">two</div>_x000D_
  <div class="table-cell">three</div>_x000D_
  <div class="table-cell">four</div>_x000D_
</div>_x000D_
<div class="table">_x000D_
  <div class="table-cell">one</div>_x000D_
  <div class="table-cell">two</div>_x000D_
  <div class="table-cell">three</div>_x000D_
  <div class="table-cell">four</div>_x000D_
</div>_x000D_
<div class="table">_x000D_
  <div class="table-cell">one</div>_x000D_
</div>

My clarification on this matter:

Basically all of the mentioned types (service, factory, provider, etc.) are just creating and configuring global variables (that are of course global to the entire application), just as old fashioned global variables were.

While global variables are not recommended, the real usage of these global variables is to provide dependency injection, by passing the variable to the relevant controller.

There are many levels of complications in creating the values for the "global variables":

1. Constant
   This defines an actual constant that should not be modified during the entire application, just like constants in other languages are (something that JavaScript lacks).
   
2. Value
   This is a modifiable value or object, and it serves as some global variable, that can even be injected when creating other services or factories (see further on these). However, it must be a "literal value", which means that one has to write out the actual value, and cannot use any computation or programming logic (in other words 39 or myText or {prop: "value"} are OK, but 2 +2 is not).
3. Factory
   A more general value, that is possible to be computed right away. It works by passing a function to AngularJS with the logic needed to compute the value and AngularJS executes it, and it saves the return value in the named variable.
   Note that it is possible to return a object (in which case it will function similar to a service) or a function (that will be saved in the variable as a callback function).
4. Service
   A service is a more stripped-down version of factory which is valid only when the value is an object, and it allows for writing any logic directly in the function (as if it would be a constructor), as well as declaring and accessing the object properties using the this keyword.
5. Provider
   Unlike a service which is a simplified version of factory, a provider is a more complex, but more flexible way of initializing the "global" variables, with the biggest flexibility being the option to set values from the app.config.
   It works like using a combination of service and provider, by passing to provider a function that has properties declared using the this keyword, which can be used from the app.config.
   Then it needs to have a separate $.get function which is executed by AngularJS after setting the above properties via the app.config file , and this $.get function behaves just as the factory above, in that its return value is used to initialize the "global" variables.

Look for exceptions being thrown and caught in the ... sections of your code. Runtime and rollbacking application exceptions cause rollback when thrown out of a business method even if caught on some other place.

You can use context to find out whether the transaction is marked for rollback.

@Resource
private SessionContext context;

context.getRollbackOnly();

I always check this way.

IF OBJECT_ID('TestXML..tblCustomer') IS NOT NULL  
BEGIN  
    PRINT 'Exist'
END  
ELSE
BEGIN
    PRINT 'Not Exist'
END 

Thanks

I was having the same problem and could not figure out what I was doing wrong. Turns out, the auto-complete for Android Studio was changing the text to either all caps or all lower case (depending on whether I typed in upper case or lower cast words before the auto-complete). The OS was not registering the name due to this issue and I would get the error regarding a missing permission. As stated above, ensure your permissions are labeled correctly:

Correct:

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

Incorrect:

<uses-permission android:name="ANDROID.PERMISSION.ACCESS_FINE_LOCATION" />

Incorrect:

<uses-permission android:name="android.permission.access_fine_location" />

Though this may seem trivial, its easy to overlook.

If there is some setting to make permissions non-case-sensitive, please add a comment with the instructions. Thank you!

Somewhere in your project, typically main.js or router.js

import Router from 'vue-router'

Router.prototype.open = function (routeObject) {
  const {href} = this.resolve(routeObject)
  window.open(href, '_blank')
}

In your component:

<div @click="$router.open({name: 'User', params: {ID: 123}})">Open in new tab</div>

Slightly off topic, but for those of you that want to modify the built-in colors of the Dark/Light themes you can use this little tool I wrote for Visual Studio 2012.

INT(10) does not mean a 10-digit number, it means an integer with a display width of 10 digits. The maximum value for an INT in MySQL is 2147483647 (or 4294967295 if unsigned).

You can use a BIGINT instead of INT to store it as a numeric. Using BIGINT will save you 3 bytes per row over VARCHAR(10).

To Store "Country + area + number separately". You can try using a VARCHAR(20), this allows you the ability to store international phone numbers properly, should that need arise.

import itertools

foos=[1.0, 2.0, 3.0, 4.0, 5.0]
bars=[1, 2, 3]

print zip(foos, itertools.cycle([bars]))

Some gotchas to watch out for:

If you double-click the batch file %0 will be surrounded by quotes. For example, if you save this file as c:\test.bat:

@echo %0
@pause

Double-clicking it will open a new command prompt with output:

"C:\test.bat"

But if you first open a command prompt and call it directly from that command prompt, %0 will refer to whatever you've typed. If you type test.batEnter, the output of %0 will have no quotes because you typed no quotes:

c:\>test.bat
test.bat

If you type testEnter, the output of %0 will have no extension too, because you typed no extension:

c:\>test
test

Same for tEsTEnter:

c:\>tEsT
tEsT

If you type "test"Enter, the output of %0 will have quotes (since you typed them) but no extension:

c:\>"test"
"test"

Lastly, if you type "C:\test.bat", the output would be exactly as though you've double clicked it:

c:\>"C:\test.bat"
"C:\test.bat"

Note that these are not all the possible values %0 can be because you can call the script from other folders:

c:\some_folder>/../teST.bAt
/../teST.bAt

All the examples shown above will also affect %~0, because the output of %~0 is simply the output of %0 minus quotes (if any).

There is a problem with all those solutions floating around using multipliers. Both kkyy and Christoph's solutions are wrong unfortunately.

Please test your code for number 551.175 with 2 decimal places - it will round to 551.17 while it should be 551.18 ! But if you test for ex. 451.175 it will be ok - 451.18. So it's difficult to spot this error at a first glance.

The problem is with multiplying: try 551.175 * 100 = 55117.49999999999 (ups!)

So my idea is to treat it with toFixed() before using Math.round();

function roundFix(number, precision)
{
    var multi = Math.pow(10, precision);
    return Math.round( (number * multi).toFixed(precision + 1) ) / multi;
}

I think the following image helps for those needing to come by T as the return type.

In comments debiasej wrote the mentioned below article explains more about design patterns (based on interfaces, classes):

http://loredanacirstea.github.io/es6-design-patterns/

Design patterns book in javascript may also be useful for you:

http://addyosmani.com/resources/essentialjsdesignpatterns/book/

Design pattern = classes + interface or multiple inheritance

An example of the factory pattern in ES6 JS (to run: node example.js):

"use strict";

// Types.js - Constructors used behind the scenes

// A constructor for defining new cars
class Car {
  constructor(options){
    console.log("Creating Car...\n");
    // some defaults
    this.doors = options.doors || 4;
    this.state = options.state || "brand new";
    this.color = options.color || "silver";
  }
}

// A constructor for defining new trucks
class Truck {
  constructor(options){
    console.log("Creating Truck...\n");
    this.state = options.state || "used";
    this.wheelSize = options.wheelSize || "large";
    this.color = options.color || "blue";
  }
}


// FactoryExample.js

// Define a skeleton vehicle factory
class VehicleFactory {}

// Define the prototypes and utilities for this factory

// Our default vehicleClass is Car
VehicleFactory.prototype.vehicleClass = Car;

// Our Factory method for creating new Vehicle instances
VehicleFactory.prototype.createVehicle = function ( options ) {

  switch(options.vehicleType){
    case "car":
      this.vehicleClass = Car;
      break;
    case "truck":
      this.vehicleClass = Truck;
      break;
    //defaults to VehicleFactory.prototype.vehicleClass (Car)
  }

  return new this.vehicleClass( options );

};

// Create an instance of our factory that makes cars
var carFactory = new VehicleFactory();
var car = carFactory.createVehicle( {
            vehicleType: "car",
            color: "yellow",
            doors: 6 } );

// Test to confirm our car was created using the vehicleClass/prototype Car

// Outputs: true
console.log( car instanceof Car );

// Outputs: Car object of color "yellow", doors: 6 in a "brand new" state
console.log( car );

var movingTruck = carFactory.createVehicle( {
                      vehicleType: "truck",
                      state: "like new",
                      color: "red",
                      wheelSize: "small" } );

// Test to confirm our truck was created with the vehicleClass/prototype Truck

// Outputs: true
console.log( movingTruck instanceof Truck );

// Outputs: Truck object of color "red", a "like new" state
// and a "small" wheelSize
console.log( movingTruck );

You can use static methods from Character class to get Numeric value from char.

char x = '9';

if (Character.isDigit(x)) { // Determines if the specified character is a digit.
    int y = Character.getNumericValue(x); //Returns the int value that the 
                                          //specified Unicode character represents.
    System.out.println(y);
}

Here's an extension method I wrote for a similar situation. My application would receive numbers in the format of 2.3 or 3.11 where the integer component of the number represented years and the fractional component represented months.

// Sample Usage
int years, months;
double test1 = 2.11;
test1.Split(out years, out months);
// years = 2 and months = 11

public static class DoubleExtensions
{
    public static void Split(this double number, out int years, out int months)
    {
        years = Convert.ToInt32(Math.Truncate(number));

        double tempMonths = Math.Round(number - years, 2);
        while ((tempMonths - Math.Floor(tempMonths)) > 0 && tempMonths != 0) tempMonths *= 10;
        months = Convert.ToInt32(tempMonths);
    }
}

An interesting idea is to use the RollingAppender as suggested here: http://shzhangji.com/blog/2015/05/31/spark-streaming-logging-configuration/ so that you don't "polute" the console space, but still be able to see the results under $YOUR_LOG_PATH_HERE/${dm.logging.name}.log.

    log4j.rootLogger=INFO, rolling

log4j.appender.rolling=org.apache.log4j.RollingFileAppender
log4j.appender.rolling.layout=org.apache.log4j.PatternLayout
log4j.appender.rolling.layout.conversionPattern=[%d] %p %m (%c)%n
log4j.appender.rolling.maxFileSize=50MB
log4j.appender.rolling.maxBackupIndex=5
log4j.appender.rolling.file=$YOUR_LOG_PATH_HERE/${dm.logging.name}.log
log4j.appender.rolling.encoding=UTF-8

Another method that solves the cause is to observe what kind of loggings do you usually have (coming from different modules and dependencies), and set for each the granularity for the logging, while turning "quiet" third party logs that are too verbose:

For instance,

    # Silence akka remoting
log4j.logger.Remoting=ERROR
log4j.logger.akka.event.slf4j=ERROR
log4j.logger.org.spark-project.jetty.server=ERROR
log4j.logger.org.apache.spark=ERROR
log4j.logger.com.anjuke.dm=${dm.logging.level}
log4j.logger.org.eclipse.jetty=WARN
log4j.logger.org.eclipse.jetty.util.component.AbstractLifeCycle=ERROR
log4j.logger.org.apache.spark.repl.SparkIMain$exprTyper=INFO
log4j.logger.org.apache.spark.repl.SparkILoop$SparkILoopInterpreter=INFO

In Java 8 that parameter is commonly used to print a warning message like this one:

Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=512m; support was removed in 8.0

The reason why you get this message in Java 8 is because Permgen has been replaced by Metaspace to address some of PermGen's drawbacks (as you were able to see for yourself, one of those drawbacks is that it had a fixed size).

FYI: an article on Metaspace: http://java-latte.blogspot.in/2014/03/metaspace-in-java-8.html

I think there are some compiler errors.

• Writeline should be WriteLine (capital 'L')

• missing semicolon at the end of a line

      double a, b;
      Console.WriteLine("istenen sayiyi sonuna .00 koyarak yaz");
      a = double.Parse(Console.ReadLine());
      b = a * Math.PI; // Missing colon!
      Console.WriteLine("Sonuç " + b);
  

BYTE *str1 = "Hello World";
std::string str2((char *)str1);  /* construct on the stack */

Alternatively:

std::string *str3 = new std::string((char *)str1); /* construct on the heap */
cout << &str3;
delete str3;

Lookout! The width attribute is clipped by the max-width attribute. So I used....

    <form method="post" style="width:1200px">
    <h4 style="width:1200px">URI <input type="text" name="srcURI" id="srcURI" value="@m.SrcURI" style="width:600px;max-width:600px"/></h4>

Fairly simple process I am using SCSS obviously but you don't have to as it's just CSS in the end!

HTML

<span class="menu">Menu</span>

SCSS

.menu {
    position: relative;
    text-decoration: none;
    font-weight: 400;
    color: blue;
    transition: all .35s ease;

    &::before {
        content: "";
        position: absolute;
        width: 100%;
        height: 2px;
        bottom: 0;
        left: 0;
        background-color: yellow;
        visibility: hidden;
        -webkit-transform: scaleX(0);
        transform: scaleX(0);
        -webkit-transition: all 0.3s ease-in-out 0s;
        transition: all 0.3s ease-in-out 0s;
    }

    &:hover {
        color: yellow;

        &::before {
            visibility: visible;
            -webkit-transform: scaleX(1);
            transform: scaleX(1);
        }
    }
}

Sometimes, this error pops up because of the kernel has reached its limit. Try to restart the kernel redo the necessary steps.

If you're coding for the kind of clarity that would be understood by someone who is just starting out with Perl, the traditional this construct says what it means, with a high degree of clarity and legibility:

$string = join ', ', @array;
print "$string\n";

This construct is documented in perldoc -fjoin.

However, I've always liked how simple $, makes it. The special variable $" is for interpolation, and the special variable $, is for lists. Combine either one with dynamic scope-constraining 'local' to avoid having ripple effects throughout the script:

use 5.012_002;
use strict;
use warnings;

my @array = qw/ 1 2 3 4 5 /;

{
    local $" = ', ';
    print "@array\n"; # Interpolation.
}

OR with $,:

use feature q(say);
use strict;
use warnings;

my @array = qw/ 1 2 3 4 5 /;
{
    local $, = ', ';

The special variables $, and $" are documented in perlvar. The local keyword, and how it can be used to constrain the effects of altering a global punctuation variable's value is probably best described in perlsub.

Note: To serialize and desirialze JSON, I used the Newtonsoft.Json NuGet package.

In current releases of nmap you can use:

sudo nmap -sn 192.168.0.*

This will print the MAC addresses of all available hosts. Of course provide your own network, subnet and host id's.

Further explanation can be found here.

In windows

$exec = 'ipconfig | findstr /R /C:"IPv4.*"';
exec($exec, $output);
preg_match('/\d+\.\d+\.\d+\.\d+/', $output[0], $matches);
print_r($matches[0]);

Use chown to change ownership and chmod to change rights.

use the -R option to apply the rights for all files inside of a directory too.

Note that both these commands just work for directories too. The -R option makes them also change the permissions for all files and directories inside of the directory.

For example

sudo chown -R username:group directory

will change ownership (both user and group) of all files and directories inside of directory and directory itself.

sudo chown username:group directory

will only change the permission of the folder directory but will leave the files and folders inside the directory alone.

you need to use sudo to change the ownership from root to yourself.

Edit:

Note that if you use chown user: file (Note the left-out group), it will use the default group for that user.

Also You can change the group ownership of a file or directory with the command:

chgrp group_name file/directory_name

You must be a member of the group to which you are changing ownership to.

You can find group of file as follows

# ls -l file
-rw-r--r-- 1 root family 0 2012-05-22 20:03 file

# chown sujit:friends file

User 500 is just a normal user. Typically user 500 was the first user on the system, recent changes (to /etc/login.defs) has altered the minimum user id to 1000 in many distributions, so typically 1000 is now the first (non root) user.

What you may be seeing is a system which has been upgraded from the old state to the new state and still has some processes knocking about on uid 500. You can likely change it by first checking if your distro should indeed now use 1000, and if so alter the login.defs file yourself, the renumber the user account in /etc/passwd and chown/chgrp all their files, usually in /home/, then reboot.

But in answer to your question, no, you should not really be worried about this in all likelihood. It'll be showing as "500" instead of a username because o user in /etc/passwd has a uid set of 500, that's all.

Also you can show your current numbers using id i'm willing to bet it comes back as 1000 for you.

An alternative solution is to introduce a method to the file instance that would do the explicit conversion.

import types

def _write_str(self, ascii_str):
    self.write(ascii_str.encode('ascii'))

source_file = open("myfile.bin", "wb")
source_file.write_str = types.MethodType(_write_str, source_file)

And then you can use it as source_file.write_str("Hello World").

You can run using the following command. Here I want to run using spring profile local:

spring-boot:run -Drun.jvmArguments="-Dspring.profiles.active=local"

In vi hit :.

Then s/Control-VControl-M//g.

Control-V Control-M are obviously those keys. Don't spell it out.

We managed to get this working exactly as described in the OP, and hopefully someone else can make use of the solution. Here's what we did:

Set up the security context like so:

<security:http realm="Protected API" use-expressions="true" auto-config="false" create-session="stateless" entry-point-ref="CustomAuthenticationEntryPoint">
    <security:custom-filter ref="authenticationTokenProcessingFilter" position="FORM_LOGIN_FILTER" />
    <security:intercept-url pattern="/authenticate" access="permitAll"/>
    <security:intercept-url pattern="/**" access="isAuthenticated()" />
</security:http>

<bean id="CustomAuthenticationEntryPoint"
    class="com.demo.api.support.spring.CustomAuthenticationEntryPoint" />

<bean id="authenticationTokenProcessingFilter"
    class="com.demo.api.support.spring.AuthenticationTokenProcessingFilter" >
    <constructor-arg ref="authenticationManager" />
</bean>

As you can see, we've created a custom AuthenticationEntryPoint, which basically just returns a 401 Unauthorized if the request wasn't authenticated in the filter chain by our AuthenticationTokenProcessingFilter.

CustomAuthenticationEntryPoint:

public class CustomAuthenticationEntryPoint implements AuthenticationEntryPoint {
    @Override
    public void commence(HttpServletRequest request, HttpServletResponse response,
            AuthenticationException authException) throws IOException, ServletException {
        response.sendError( HttpServletResponse.SC_UNAUTHORIZED, "Unauthorized: Authentication token was either missing or invalid." );
    }
}

AuthenticationTokenProcessingFilter:

public class AuthenticationTokenProcessingFilter extends GenericFilterBean {

    @Autowired UserService userService;
    @Autowired TokenUtils tokenUtils;
    AuthenticationManager authManager;

    public AuthenticationTokenProcessingFilter(AuthenticationManager authManager) {
        this.authManager = authManager;
    }

    @Override
    public void doFilter(ServletRequest request, ServletResponse response,
            FilterChain chain) throws IOException, ServletException {
        @SuppressWarnings("unchecked")
        Map<String, String[]> parms = request.getParameterMap();

        if(parms.containsKey("token")) {
            String token = parms.get("token")[0]; // grab the first "token" parameter

            // validate the token
            if (tokenUtils.validate(token)) {
                // determine the user based on the (already validated) token
                UserDetails userDetails = tokenUtils.getUserFromToken(token);
                // build an Authentication object with the user's info
                UsernamePasswordAuthenticationToken authentication = 
                        new UsernamePasswordAuthenticationToken(userDetails.getUsername(), userDetails.getPassword());
                authentication.setDetails(new WebAuthenticationDetailsSource().buildDetails((HttpServletRequest) request));
                // set the authentication into the SecurityContext
                SecurityContextHolder.getContext().setAuthentication(authManager.authenticate(authentication));         
            }
        }
        // continue thru the filter chain
        chain.doFilter(request, response);
    }
}

Obviously, TokenUtils contains some privy (and very case-specific) code and can't be readily shared. Here's its interface:

public interface TokenUtils {
    String getToken(UserDetails userDetails);
    String getToken(UserDetails userDetails, Long expiration);
    boolean validate(String token);
    UserDetails getUserFromToken(String token);
}

That ought to get you off to a good start. Happy coding. :)

I can't comment because my reputation is not high enough. @Franklin Rivero if you are using Laravel 5.2 you can set the bindings on the main query instead of the join using the setBindings method.

So the main query in @ph4r05's answer would look something like this:

$q = DnsResult::query()
    ->from($dnsTable . ' AS s')
    ->join(
        DB::raw('(' . $qqSql. ') AS ss'),
        function(JoinClause $join) {
            $join->on('s.watch_id', '=', 'ss.watch_id')
                 ->on('s.last_scan_at', '=', 'ss.last_scan');
        })
    ->setBindings($subq->getBindings());

Please note that PrimeFaces supports the standard JSF 2.0+ keywords:

• @this Current component.
• @all Whole view.
• @form Closest ancestor form of current component.
• @none No component.

and the standard JSF 2.3+ keywords:

• @child(n) nth child.
• @composite Closest composite component ancestor.
• @id(id) Used to search components by their id ignoring the component tree structure and naming containers.
• @namingcontainer Closest ancestor naming container of current component.
• @parent Parent of the current component.
• @previous Previous sibling.
• @next Next sibling.
• @root UIViewRoot instance of the view, can be used to start searching from the root instead the current component.

But, it also comes with some PrimeFaces specific keywords:

• @row(n) nth row.
• @widgetVar(name) Component with given widgetVar.

And you can even use something called "PrimeFaces Selectors" which allows you to use jQuery Selector API. For example to process all inputs in a element with the CSS class myClass:

process="@(.myClass :input)"

See:

• https://primefaces.github.io/primefaces/10_0_0/#/core/searchexpression

If you have a SharedPreferenceActivity by which you have saved your values

SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(this);
String imgSett = prefs.getString(keyChannel, "");

if the value is saved in a SharedPreference in an Activity then this is the correct way to saving it.

SharedPreferences shared = getSharedPreferences(PREF_NAME, MODE_PRIVATE);
SharedPreferences.Editor editor = shared.edit();
editor.putString(keyChannel, email);
editor.commit();// commit is important here.

and this is how you can retrieve the values.

SharedPreferences shared = getSharedPreferences(PREF_NAME, MODE_PRIVATE);
String channel = (shared.getString(keyChannel, ""));

Also be aware that you can do so in a non-Activity class too but the only condition is that you need to pass the context of the Activity. use this context in to get the SharedPreferences.

mContext.getSharedPreferences(PREF_NAME, MODE_PRIVATE);

This might depend on how much you want to engineer the solution - if the array is never going to be that big and you don't care about sorting the list you might want to try something similar to the following:

    public string[] RemoveDuplicates(string[] myList) {
        System.Collections.ArrayList newList = new System.Collections.ArrayList();

        foreach (string str in myList)
            if (!newList.Contains(str))
                newList.Add(str);
        return (string[])newList.ToArray(typeof(string));
    }

delete_all is a single SQL DELETE statement and nothing more. destroy_all calls destroy() on all matching results of :conditions (if you have one) which could be at least NUM_OF_RESULTS SQL statements.

If you have to do something drastic such as destroy_all() on large dataset, I would probably not do it from the app and handle it manually with care. If the dataset is small enough, you wouldn't hurt as much.

As Shubham Jain stated, this is working to me: driver.findElement(By.id("invoice_supplier_id")).sendKeys("value"??, "new value");

See man git merge (HOW TO RESOLVE CONFLICTS):

After seeing a conflict, you can do two things:

• Decide not to merge. The only clean-ups you need are to reset the index file to the HEAD commit to reverse 2. and to clean up working tree changes made by 2. and 3.; git-reset --hard can be used for this.

• Resolve the conflicts. Git will mark the conflicts in the working tree. Edit the files into shape and git add them to the index. Use git commit to seal the deal.

And under TRUE MERGE (to see what 2. and 3. refers to):

When it is not obvious how to reconcile the changes, the following happens:

1. The HEAD pointer stays the same.

2. The MERGE_HEAD ref is set to point to the other branch head.

3. Paths that merged cleanly are updated both in the index file and in your working tree.

4. ...

So: use git reset --hard if you want to remove the stash changes from your working tree, or git reset if you want to just clean up the index and leave the conflicts in your working tree to merge by hand.

Under man git stash (OPTIONS, pop) you can read in addition:

Applying the state can fail with conflicts; in this case, it is not removed from the stash list. You need to resolve the conflicts by hand and call git stash drop manually afterwards.

val() returns the value of the <select> element, i.e. the value attribute of the selected <option> element.

Since you actually want the inner text of the selected <option> element, you should match that element and use text() instead:

var nationality = $("#dancerCountry option:selected").text();

Please note that you should not use any png when you are testing this , first work with jpg .

$myImage = "images/logos/mylogo.jpg";  // this is where you get your Image

$pdf->Image($myImage, 5, $pdf->GetY(), 33.78);

How about this simple solution:

const sortCompareByCityPrice = (a, b) => {
    let comparison = 0
    // sort by first criteria
    if (a.city > b.city) {
        comparison = 1
    }
    else if (a.city < b.city) {
        comparison = -1
    }
    // If still 0 then sort by second criteria descending
    if (comparison === 0) {
        if (parseInt(a.price) > parseInt(b.price)) {
            comparison = -1
        }
        else if (parseInt(a.price) < parseInt(b.price)) {
            comparison = 1
        }
    }
    return comparison 
}

Based on this question javascript sort array by multiple (number) fields

also a slightly different version. i just did a appllication.sheets.count to know how many worksheets i have additionallyl. well and put a little rename in aswell

Sub insertworksheet()
    Dim worksh As Integer

    worksh = Application.Sheets.Count
    worksheetexists = False
    For x = 1 To worksh
        If Worksheets(x).Name = "ENTERWROKSHEETNAME" Then
            worksheetexists = True
            'Debug.Print worksheetexists
            Exit For
        End If
    Next x
    If worksheetexists = False Then
        Debug.Print "transformed exists"
        Worksheets.Add after:=Worksheets(Worksheets.Count)
        ActiveSheet.Name = "ENTERNAMEUWANTTHENEWONE"
    End If
End Sub

Add CDATA to your string resource

Never alter the container you're looping on, because iterators on that container are not going to be informed of your alterations and, as you've noticed, that's quite likely to produce a very different loop and/or an incorrect one. In normal cases, looping on a copy of the container helps, but in your case it's clear that you don't want that, as the container will be empty after 50 legs of the loop and if you then try popping again you'll get an exception.

What's anything BUT clear is, what behavior are you trying to achieve, if any?! Maybe you can express your desires with a while...?

i = 0
while i < len(some_list):
    print i,                         
    print some_list.pop(0),                  
    print some_list.pop(0)

If you are dealing with a Series of type DateTime there is a more efficient way to truncate them, specially when the Series object has a lot of rows.

You can use the floor function

For example, if you want to truncate it to hours:

Generate a range of dates

times = pd.Series(pd.date_range(start='1/1/2018 04:00:00', end='1/1/2018 22:00:00', freq='s'))

We can check it comparing the running time between the replace and the floor functions.

%timeit times.apply(lambda x : x.replace(minute=0, second=0, microsecond=0))
>>> 341 ms ± 18.2 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)

%timeit times.dt.floor('h')
>>>>2.26 ms ± 451 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)

Simple and easy way to update the cursor

UPDATE Cursor
SET Cursor.CODE = Cursor.New_CODE
FROM (
  SELECT CODE, ROW_NUMBER() OVER (ORDER BY [CODE]) AS New_CODE
  FROM Table Where CODE BETWEEN 1000 AND 1999
  ) Cursor

Check the version of the Entity Framework.

if it is 6.3, downgrade it to 6.2 and it should work just fine

I would use compileall. It works nicely both from scripts and from the command line. It's a bit higher level module/tool than the already mentioned py_compile that it also uses internally.

If the list is in random order, you can just take the first 50.

Otherwise, use

import random
random.sample(the_list, 50)

random.sample help text:

sample(self, population, k) method of random.Random instance
    Chooses k unique random elements from a population sequence.

    Returns a new list containing elements from the population while
    leaving the original population unchanged.  The resulting list is
    in selection order so that all sub-slices will also be valid random
    samples.  This allows raffle winners (the sample) to be partitioned
    into grand prize and second place winners (the subslices).

    Members of the population need not be hashable or unique.  If the
    population contains repeats, then each occurrence is a possible
    selection in the sample.

    To choose a sample in a range of integers, use xrange as an argument.
    This is especially fast and space efficient for sampling from a
    large population:   sample(xrange(10000000), 60)

print("the furnace is now " + str(temperature) + "degrees!")

cast it to str

Yes you need javascript. The simplest way is to just put this at the bottom of your HTML page:

<script type="text/javascript">
alert("Hello world");
</script>

There are more preferred methods, like using jQuery's ready function, but this method will work.

For input field validation you can do:

<input ng-model="discount" type="number" ng-attr-max="{{discountType == '%' ? 100 : undefined}}">

This will apply the attribute max to 100 only if discountType is defined as %

If you use Sqlite's REGEXP support ( see the answer at Problem with regexp python and sqlite for how to do that ) , then you can do it easily in one clause:

SELECT word FROM table WHERE word NOT REGEXP '[abc]';

You could use a lookahead:

re.split(r'[ ](?=[A-Z]+\b)', input)

This will split at every space that is followed by a string of upper-case letters which end in a word-boundary.

Note that the square brackets are only for readability and could as well be omitted.

If it is enough that the first letter of a word is upper case (so if you would want to split in front of Hello as well) it gets even easier:

re.split(r'[ ](?=[A-Z])', input)

Now this splits at every space followed by any upper-case letter.

I had the same problem, but believe it or not is was a case of case sensitivity.

This on localhost: http://localhost/.../getdata.php?id=3

Did not behave the same as this on the server: http://server/.../getdata.php?id=3

Changing the server url to this (notice the capital D in getData) solved my issue. http://localhost/.../getData.php?id=3

In case anyone has this problem with Angular 9, this is how I manage to fix it.

I started with the solution with #scrollMe [scrollTop]="scrollMe.scrollHeight" and I got the ExpressionChangedAfterItHasBeenCheckedError error as people mentioned.

In order to fix this one I just add in my ts component:

@Component({
    changeDetection: ChangeDetectionStrategy.OnPush,
...})

 constructor(private cdref: ChangeDetectorRef) {}

 ngAfterContentChecked() {
        this.cdref.detectChanges();
    }

ExpressionChangedAfterItHasBeenCheckedError: Expression has changed after it was checked. Previous value: 'undefined'

In Jackson 2.0 and later you can simply use:

import com.fasterxml.jackson.annotation.JsonAutoDetect;
import com.fasterxml.jackson.annotation.PropertyAccessor;
import com.fasterxml.jackson.databind.ObjectMapper;   

...

ObjectMapper mapper = new ObjectMapper();    
mapper.setVisibility(PropertyAccessor.ALL, Visibility.NONE);
mapper.setVisibility(PropertyAccessor.FIELD, Visibility.ANY);

to turn off autodetection.

Technically you can apply styles programmatically, with custom views anyway:

private MyRelativeLayout extends RelativeLayout {
  public MyRelativeLayout(Context context) {
     super(context, null, R.style.LightStyle);
  }
}

The one argument constructor is the one used when you instantiate views programmatically.

So chain this constructor to the super that takes a style parameter.

RelativeLayout someLayout = new MyRelativeLayout(new ContextThemeWrapper(this,R.style.RadioButton));

Or as @Dori pointed out simply:

RelativeLayout someLayout = new RelativeLayout(new ContextThemeWrapper(activity,R.style.LightStyle));

Now in Kotlin:

class MyRelativeLayout @JvmOverloads constructor(
    context: Context, 
    attributeSet: AttributeSet? = null, 
    defStyleAttr: Int = R.style.LightStyle,
) : RelativeLayout(context, attributeSet, defStyleAttr)

or

 val rl = RelativeLayout(ContextThemeWrapper(activity, R.style.LightStyle))

You can use like:

"12-18" -like "*-*"

Or split for contains:

"12-18" -split "" -contains "-"

Here's some code I use to deal with this.

First we show the element, which will typically set the display type to "block" via .show() function, and then set the CSS rule to "visible":

jQuery( '.element' ).show().css( 'visibility', 'visible' );

Or, assuming that the class that is hiding the element is called hidden, such as in Twitter Bootstrap, toggleClass() can be useful:

jQuery( '.element' ).toggleClass( 'hidden' );

Lastly, if you want to chain functions, perhaps with fancy with a fading effect, you can do it like so:

jQuery( '.element' ).css( 'visibility', 'visible' ).fadeIn( 5000 );

Not difficult, check this.

<button @click="disabled = !disabled">Toggle Enable</button>
<input type="text" id="name" class="form-control" name="name"  v-model="form.name" :disabled="disabled">

gc() can help

saving data as .RData, closing, re-opening R, and loading the RData can help.

see my answer here: https://stackoverflow.com/a/24754706/190791 for more details

No, you cannot reference one rule-set from another.

You can, however, reuse selectors on multiple rule-sets within a stylesheet and use multiple selectors on a single rule-set (by separating them with a comma).

.opacity, .someDiv {
    filter:alpha(opacity=60);
    -moz-opacity:0.6;
    -khtml-opacity: 0.6;
    opacity: 0.6; 
}
.radius, .someDiv {
    border-top-left-radius: 15px;
    border-top-right-radius: 5px;
    -moz-border-radius-topleft: 10px;
    -moz-border-radius-topright: 10px;    
}

You can also apply multiple classes to a single HTML element (the class attribute takes a space separated list).

<div class="opacity radius">

Either of those approaches should solve your problem.

It would probably help if you used class names that described why an element should be styled instead of how it should be styled. Leave the how in the stylesheet.

You can use Cell.Interior.Color, I've used it to count the number of cells in a range that have a given background color (ie. matching my legend).

file_name=test.log

# set first K lines:
K=1000

# line count (N): 
N=$(wc -l < $file_name)

# length of the bottom file:
L=$(( $N - $K ))

# create the top of file: 
head -n $K $file_name > top_$file_name

# create bottom of file: 
tail -n $L $file_name > bottom_$file_name

Also, on second thought, split will work in your case, since the first split is larger than the second. Split puts the balance of the input into the last split, so

split -l 300000 file_name

will output xaa with 300k lines and xab with 100k lines, for an input with 400k lines.

SQL Server 2016 Answer

With SQL Server 2016 you can now do (MSDN Source):

DROP VIEW IF EXISTS dbo.MyView

start your command prompt with run as administrator

I think its better to avoid recursion because its costly.

function padLeft(str,size,padwith) {_x000D_
 if(size <= str.length) {_x000D_
        // not padding is required._x000D_
  return str;_x000D_
 } else {_x000D_
        // 1- take array of size equal to number of padding char + 1. suppose if string is 55 and we want 00055 it means we have 3 padding char so array size should be 3 + 1 (+1 will explain below)_x000D_
        // 2- now join this array with provided padding char (padwith) or default one ('0'). so it will produce '000'_x000D_

I can offer you a jquery solution

add this in your <head></head> tag

<script type="text/javascript" src="http://code.jquery.com/jquery-1.10.2.min.js"></script>

add this after </ul>

 <script> $('ul li:first').remove(); </script> 

All these answers are not allowed now. Here is the correct one:

For all those still looking for the Answer:

Here is how OLA Cabs and other such apps are doing it.

Add this in your onCreate

if (googleApiClient == null) {
    googleApiClient = new GoogleApiClient.Builder(this)
            .addApi(LocationServices.API).addConnectionCallbacks(this)
            .addOnConnectionFailedListener(Login.this).build();
    googleApiClient.connect();
            LocationRequest locationRequest = LocationRequest.create();
    locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
    locationRequest.setInterval(30 * 1000);
    locationRequest.setFastestInterval(5 * 1000);
    LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder()
            .addLocationRequest(locationRequest);

    // **************************
    builder.setAlwaysShow(true); // this is the key ingredient
    // **************************

    PendingResult<LocationSettingsResult> result = LocationServices.SettingsApi
            .checkLocationSettings(googleApiClient, builder.build());
    result.setResultCallback(new ResultCallback<LocationSettingsResult>() {
        @Override
        public void onResult(LocationSettingsResult result) {
            final Status status = result.getStatus();
            final LocationSettingsStates state = result
                    .getLocationSettingsStates();
            switch (status.getStatusCode()) {
            case LocationSettingsStatusCodes.SUCCESS:
                // All location settings are satisfied. The client can
                // initialize location
                // requests here.
                break;
            case LocationSettingsStatusCodes.RESOLUTION_REQUIRED:
                // Location settings are not satisfied. But could be
                // fixed by showing the user
                // a dialog.
                try {
                    // Show the dialog by calling
                    // startResolutionForResult(),
                    // and check the result in onActivityResult().
                    status.startResolutionForResult(Login.this, 1000);
                } catch (IntentSender.SendIntentException e) {
                    // Ignore the error.
                }
                break;
            case LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE:
                // Location settings are not satisfied. However, we have
                // no way to fix the
                // settings so we won't show the dialog.
                break;
            }
        }
    });
}

These are the implmented methods:

@Override
public void onConnected(Bundle arg0) {
    // TODO Auto-generated method stub

}

@Override
public void onConnectionSuspended(int arg0) {
    // TODO Auto-generated method stub

}

@Override
public void onConnectionFailed(ConnectionResult arg0) {
    // TODO Auto-generated method stub

}

Edit: Adding Irfan Raza's comment for more help.

@Override protected void onActivityResult(int requestCode, int resultCode, Intent data) {
     if (requestCode == 1000) {
         if(resultCode == Activity.RESULT_OK){
             String result=data.getStringExtra("result"); 
         } if (resultCode == Activity.RESULT_CANCELED) {
             //Write your code if there's no result 
         } 
    } 
} 

The pattern you want is something like this in multiline mode:

^\s*$

Explanation:

• ^ is the beginning of string anchor.
• $ is the end of string anchor.
• \s is the whitespace character class.
• * is zero-or-more repetition of.

In multiline mode, ^ and $ also match the beginning and end of the line.

References:

• regular-expressions.info/Anchors, Character Classes, and Repetition.

A non-regex alternative:

You can also check if a given string line is "blank" (i.e. containing only whitespaces) by trim()-ing it, then checking if the resulting string isEmpty().

In Java, this would be something like this:

if (line.trim().isEmpty()) {
    // line is "blank"
}

The regex solution can also be simplified without anchors (because of how matches is defined in Java) as follows:

if (line.matches("\\s*")) {
    // line is "blank"
}

API references

• String String.trim()
  • Returns a copy of the string, with leading and trailing whitespace omitted.
• boolean String.isEmpty()
  • Returns true if, and only if, length() is 0.
• boolean String.matches(String regex)
  • Tells whether or not this (entire) string matches the given regular expression.

Here's the formula used by Android:

px = dp * (dpi / 160)

Where dpi is one of the following screen densities. For a list of all possible densities go here

It defines the "DENSITY_*" constants.

• ldpi (low) ~120dpi
• mdpi (medium) ~160dpi
• hdpi (high) ~240dpi
• xhdpi (extra-high) ~320dpi
• xxhdpi (extra-extra-high) ~480dpi
• xxxhdpi (extra-extra-extra-high) ~640dpi

Taken from here.

This will sort out a lot of the confusion when translating between px and dp, if you know your screen dpi.

So, let's say you want an image of 60 dp for an hdpi screen then the physical pixel size of 60 dp is:

px = 60 * (240 / 160)

The command git branch -a shows remote branches that exist in your local repository. This may sound a bit confusing but to understand it, you have to understand that there is a difference between a remote branch, and a branch that exists in a remote repository. Remote branches are local branches that map to branches of the remote repository. So the set of remote branches represent the state of the remote repository.

The usual way to update the list of remote branches is to use git fetch. This automatically gets an updated list of branches from the remote and sets up remote branches in the local repository, also fetching any commit objects you may be missing.

However, by default, git fetch does not remove remote branches that no longer have a counterpart branch on the remote. In order to do that, you explicitly need to prune the list of remote branches:

git fetch --prune

This will automatically get rid of remote branches that no longer exist on the remote. Afterwards, git branch -r will show you an updated list of branches that really exist on the remote: And those you can delete using git push.

That being said, in order to use git push --delete, you need to specify the name of the branch on the remote repository; not the name of your remote branch. So to delete the branch test (represented by your remote branch origin/test), you would use git push origin --delete test.

If you are using Flutter just run:

flutter doctor --android-licenses 

And accept all the licenses needed.

First() is causing this if your select returns 0 rows. You either have to catch that exception, or use FirstOrDefault() which will return null in case of no elements.

I have been toying with this idea too, but I was trying to achieve a slightly different behavior. My idea was to make a list which inherits itself, thus creating a data structure that by nature allows you to embed lists within lists within lists within lists...infinitely!

Implementation

//InfiniteList<T> is a list of itself...
public class InfiniteList<T> : List<InfiniteList<T>>
{
    //This is necessary to allow your lists to store values (of type T).
    public T Value { set; get; }
}

T is a generic type parameter. It is there to ensure type safety in your class. When you create an instance of InfiniteList, you replace T with the type you want your list to be populated with, or in this instance, the type of the Value property.

Example

//The InfiniteList.Value property will be of type string
InfiniteList<string> list = new InfiniteList<string>();

A "working" example of this, where T is in itself, a List of type string!

//Create an instance of InfiniteList where T is List<string>
InfiniteList<List<string>> list = new InfiniteList<List<string>>();

//Add a new instance of InfiniteList<List<string>> to "list" instance.
list.Add(new InfiniteList<List<string>>());

//access the first element of "list". Access the Value property, and add a new string to it.
list[0].Value.Add("Hello World");

Try the following, but before running it note that the -k flag will kill any running processes keeping the device busy.

The -i flag makes fuser ask before killing.

fuser -kim /address  # kill any processes accessing file
unmount /address

Use strtotime():

$time=strtotime($dateValue);
$month=date("F",$time);
$year=date("Y",$time);

If you want to set $_POST['text'] to another value, why not use:

$_POST['text'] = $var;

on next.php?

Jquery VS javascript, I am completely against the OP in this question. Comparison happens with two similar things, not in such case.

Jquery is Javascript. A javascript library to reduce vague coding, collection commonly used javascript functions which has proven to help in efficient and fast coding.

Javascript is the source, the actual scripts that browser responds to.

All these answers around here, as well as the answers in this question, suggest that loading absolute URLs, like "/foo/bar.properties" treated the same by class.getResourceAsStream(String) and class.getClassLoader().getResourceAsStream(String). This is NOT the case, at least not in my Tomcat configuration/version (currently 7.0.40).

MyClass.class.getResourceAsStream("/foo/bar.properties"); // works!  
MyClass.class.getClassLoader().getResourceAsStream("/foo/bar.properties"); // does NOT work!

Sorry, I have absolutely no satisfying explanation, but I guess that tomcat does dirty tricks and his black magic with the classloaders and cause the difference. I always used class.getResourceAsStream(String) in the past and haven't had any problems.

PS: I also posted this over here

Create a C# class that maps to your Json and use Newsoft JsonConvert to Deserialise it.

For example:

public Class MyResponse
{
    public Meta Meta { get; set; }
    public Response Response { get; set; }
}

extension String{

    func widthWithConstrainedHeight(_ height: CGFloat, font: UIFont) -> CGFloat {
        let constraintRect = CGSize(width: CGFloat.greatestFiniteMagnitude, height: height)

        let boundingBox = self.boundingRect(with: constraintRect, options: NSStringDrawingOptions.usesLineFragmentOrigin, attributes: [NSFontAttributeName: font], context: nil)

        return ceil(boundingBox.width)
    }

    func heightWithConstrainedWidth(_ width: CGFloat, font: UIFont) -> CGFloat? {
        let constraintRect = CGSize(width: width, height: CGFloat.greatestFiniteMagnitude)
        let boundingBox = self.boundingRect(with: constraintRect, options: NSStringDrawingOptions.usesLineFragmentOrigin, attributes: [NSFontAttributeName: font], context: nil)

        return ceil(boundingBox.height)
    }

}

You can use Environment Replacement in your Dockerfile as follows:

ENV PATH="/opt/gtk/bin:${PATH}"

With androidx, the classic support libraries no longer work.

Simple solution is to use following code

In your build.gradle file

android{
  ...
  ...
  defaultConfig {
     ...
     ...
     multiDexEnabled true
  }
  ...
}

dependencies {
  ...
  ...
  implementation 'androidx.multidex:multidex:2.0.1'
}

And in your manifest just add name attribute to the application tag

<manifest ...>
    <application
        android:name="androidx.multidex.MultiDexApplication"
     ...
     ...>
         ...
         ...
    </application>
</manifest>

If your application is targeting API 21 or above multidex is enables by default.

Now if you want to get rid of many of the issues you face trying to support multidex - first try using code shrinking by setting minifyEnabled true.

Private variables in python is more or less a hack: the interpreter intentionally renames the variable.

class A:
    def __init__(self):
        self.__var = 123
    def printVar(self):
        print self.__var

Now, if you try to access __var outside the class definition, it will fail:

 >>>x = A()
 >>>x.__var # this will return error: "A has no attribute __var"

 >>>x.printVar() # this gives back 123

But you can easily get away with this:

 >>>x.__dict__ # this will show everything that is contained in object x
               # which in this case is something like {'_A__var' : 123}

 >>>x._A__var = 456 # you now know the masked name of private variables
 >>>x.printVar() # this gives back 456

You probably know that methods in OOP are invoked like this: x.printVar() => A.printVar(x), if A.printVar() can access some field in x, this field can also be accessed outside A.printVar()...after all, functions are created for reusability, there is no special power given to the statements inside.

The game is different when there is a compiler involved (privacy is a compiler level concept). It know about class definition with access control modifiers so it can error out if the rules are not being followed at compile time

Most of the answers are from the Xcode 4-5 era. I recommend an ignore file in a modern style.

We can also do the same using java 8.

public static<T> List<T> reverseList(List<T> list) {
        List<T> reverse = new ArrayList<>(list.size());

        list.stream()
                .collect(Collectors.toCollection(LinkedList::new))
                .descendingIterator()
                .forEachRemaining(reverse::add);

        return reverse;
    }

It depends on how you store the parsed CSV, but generally you want the del operator.

If you have an array of dicts:

input = [ {'day':01, 'month':04, 'year':2001, ...}, ... ]
for E in input: del E['year']

If you have an array of arrays:

input = [ [01, 04, 2001, ...],
          [...],
          ...
        ]
for E in input: del E[2]

The best place to understand the difference is at the official documentation on values / values_list. It has many useful examples and explains it very clearly. The django docs are very user freindly.

Here's a short snippet to keep SO reviewers happy:

values

Returns a QuerySet that returns dictionaries, rather than model instances, when used as an iterable.

And read the section which follows it:

value_list

This is similar to values() except that instead of returning dictionaries, it returns tuples when iterated over.

I'm assume you cannot get css working for your button using anchor tag. So you need to override the css styles which are being overwritten by other elements using !important property.

HTML

<a href="#" class="selected_btn" data-role="button">Button name</a>

CSS

.selected_btn
{
    border:1px solid red;
    text-decoration:none;
    font-family:helvetica;
    color:red !important;            
    background:url('http://www.lessardstephens.com/layout/images/slideshow_big.png') repeat-x;
}

Here is the demo

The cleaner way to do this would be to inherit RouteAware and implement the onNavigationEnd() method.

It's part of a library called @bespunky/angular-zen.

1. npm install @bespunky/angular-zen

2. Make your AppComponent extend RouteAware and add an onNavigationEnd() method.

import { Component     } from '@angular/core';
import { NavigationEnd } from '@angular/router';
import { RouteAware    } from '@bespunky/angular-zen/router-x';

@Component({
    selector   : 'app-root',
    templateUrl: './app.component.html',
    styleUrls  : ['./app.component.css']
})
export class AppComponent extends RouteAware
{    
    protected onNavigationEnd(event: NavigationEnd): void
    {
        // Handle authentication...
    }
}

RouteAware has other benefits such as:
? Any router event can have a handler method (Angular's supported router events).
? Use this.router to access the router
? Use this.route to access the activated route
? Use this.componentBus to access the RouterOutletComponentBus service

This is kinda ugly, but its the first thing that popped in my head. This also should allow you to pass in arguments:

eval('var myfunc = ' + variable);  myfunc(args, ...);

If you don't need to pass in arguments this might be simpler.

eval(variable + '();');

Standard dry-code warning applies.

The way you are using await/async is poor at best, and it makes it hard to follow. You are mixing await with Task'1.Result, which is just confusing. However, it looks like you are looking at a final task result, rather than the contents.

I've rewritten your function and function call, which should fix your issue:

async Task<string> GetResponseString(string text)
{
    var httpClient = new HttpClient();

    var parameters = new Dictionary<string, string>();
    parameters["text"] = text;

    var response = await httpClient.PostAsync(BaseUri, new FormUrlEncodedContent(parameters));
    var contents = await response.Content.ReadAsStringAsync();

    return contents;
}

And your final function call:

Task<string> result = GetResponseString(text);
var finalResult = result.Result;

Or even better:

var finalResult = await GetResponseString(text);

jQuery way to change value on text input field is:

$('#colorpickerField1').attr('value', '#000000')

this will change attribute value for the DOM element with ID #colorpickerField1 from #EEEEEE to #000000

This is an alternative:

- name: Install this only for local dev machine
  pip: name=pyramid
  delegate_to: localhost

Read the image, convert it to byte[], then return a File() with a content type.

public ActionResult ImageResult(Image image, ImageFormat format, string contentType) {
  using (var stream = new MemoryStream())
    {
      image.Save(stream, format);
      return File(stream.ToArray(), contentType);
    }
  }
}

Here are the usings:

using System.Drawing;
using System.Drawing.Imaging;
using System.IO;
using Microsoft.AspNetCore.Mvc;

For performance reasons, the use of += (String concatenation) is discouraged. The reason why is: Java String is an immutable, every time a new concatenation is done a new String is created (the new one has a different fingerprint from the older one already in the String pool ). Creating new strings puts pressure on the GC and slows down the program: object creation is expensive.

Below code should make it more practical and clear at the same time.

public static void main(String[] args) 
{
    // warming up
    for(int i = 0; i < 100; i++)
        RandomStringUtils.randomAlphanumeric(1024);
    final StringBuilder appender = new StringBuilder();
    for(int i = 0; i < 100; i++)
        appender.append(RandomStringUtils.randomAlphanumeric(i));

    // testing
    for(int i = 1; i <= 10000; i*=10)
        test(i);
}

public static void test(final int howMany) 
{
    List<String> samples = new ArrayList<>(howMany);
    for(int i = 0; i < howMany; i++)
        samples.add(RandomStringUtils.randomAlphabetic(128));

    final StringBuilder builder = new StringBuilder();
    long start = System.nanoTime();
    for(String sample: samples)
        builder.append(sample);
    builder.toString();
    long elapsed = System.nanoTime() - start;
    System.out.printf("builder - %d - elapsed: %dus\n", howMany, elapsed / 1000);

    String accumulator = "";
    start = System.nanoTime();
    for(String sample: samples)
        accumulator += sample;
    elapsed = System.nanoTime() - start;
    System.out.printf("concatenation - %d - elapsed: %dus\n", howMany, elapsed / (int) 1e3);

    start = System.nanoTime();
    String newOne = null;
    for(String sample: samples)
        newOne = new String(sample);
    elapsed = System.nanoTime() - start;
    System.out.printf("creation - %d - elapsed: %dus\n\n", howMany, elapsed / 1000);
}

Results for a run are reported below.

builder - 1 - elapsed: 132us
concatenation - 1 - elapsed: 4us
creation - 1 - elapsed: 5us

builder - 10 - elapsed: 9us
concatenation - 10 - elapsed: 26us
creation - 10 - elapsed: 5us

builder - 100 - elapsed: 77us
concatenation - 100 - elapsed: 1669us
creation - 100 - elapsed: 43us

builder - 1000 - elapsed: 511us
concatenation - 1000 - elapsed: 111504us
creation - 1000 - elapsed: 282us

builder - 10000 - elapsed: 3364us 
concatenation - 10000 - elapsed: 5709793us
creation - 10000 - elapsed: 972us

Not considering the results for 1 concatenation (JIT was not yet doing its job), even for 10 concatenations the performance penalty is relevant; for thousands of concatenations, the difference is huge.

Lessons learned from this very quick experiment (easily reproducible with the above code): never use the += to concatenate strings together, even in very basic cases where a few concatenations are needed (as said, creating new strings is expensive anyway and puts pressure on the GC).

In my case it was the lockfile postmaster.id that was not deleted properly during the last system crash that caused the issue. Deleting it with sudo rm /usr/local/var/postgres/postmaster.pid and restarting Postgres solved the problem.

Install 7zip (or download the command line version instead) and use this PowerShell method:

function create-7zip([String] $aDirectory, [String] $aZipfile){
    [string]$pathToZipExe = "$($Env:ProgramFiles)\7-Zip\7z.exe";
    [Array]$arguments = "a", "-tzip", "$aZipfile", "$aDirectory", "-r";
    & $pathToZipExe $arguments;
}

You can the call it like this:

create-7zip "c:\temp\myFolder" "c:\temp\myFolder.zip"

Remove the public keyword from int[] locations={1,2,3};. An access modifier isn't allowed inside a method, as its accessbility is defined by its method scope.

If your goal is to use this reference in many a method, you might want to move the declaration outside the method.

If you want it to be List<string>, get rid of the anonymous type and add a .ToList() call:

List<string> list = (from char c in source
                     select c.ToString()).ToList();

Here's how I would make the next ID:

INSERT INTO table_name (
            ID,
            FIRSTNAME,
            SURNAME) 
            VALUES ((( 
                    SELECT COALESCE(MAX(B.ID)+1,1) AS NEXTID 
                        FROM table_name B
                        )), John2, Smith2);

With this you can make sure that even if the table ID is NULL, it will still work perfectly.

Try this way. make a loop inside java script function to wait until the ajax call finished.

function getLabelById(id)
{
    var label = '';
    var done = false;
    $.ajax({
       cache: false,
       url: "YourMvcActionUrl",
       type: "GET",
       dataType: "json",
       async: false,
       error: function (result) {
         label='undefined';
         done = true;
        },
       success: function (result) {
            label = result.Message;
            done = true;
        }
     });

   //A loop to check done if ajax call is done.
   while (!done)
   {
      setTimeout(function(){ },500); // take a sleep.
   }

    return label;
}

The debugger should automatically attach to the browser with Visual Studio 2012. You can use the debugger keyword to halt at a certain point in the application or use the breakpoints directly inside VS.

You can also detatch the default debugger in Visual Studio and use the Developer Tools which come pre loaded with Internet Explorer or FireBug etc.

To do this goto Visual Studio -> Debug -> Detatch All and then click Start debugging in Internet Explorer. You can then set breakpoints at this level.

This answer might be very helpful for this problem. In addition, for my case, exporting the service as default was the cause.

WRONG:

@Inject()
export default class MobileService { ... }

CORRECT:

@Inject()
export class MobileService { ... }

Minor note: Please consider that when you import from a default export, the naming is completely independent. This actually has an impact on refactorings.

Let's say you have a class Foo like this with a corresponding import:

export default class Foo { }

// The name 'Foo' could be anything, since it's just an
// Identifier for the default export
import Foo from './Foo'

Now if you refactor your Foo class to be Bar and also rename the file, most IDEs will NOT touch your import. So you will end up with this:

export default class Bar { }

// The name 'Foo' could be anything, since it's just an
// Identifier for the default export.
import Foo from './Bar'

Especially in TypeScript, I really appreciate named exports and the more reliable refactoring. The difference is just the lack of the default keyword and the curly braces. This btw also prevents you from making a typo in your import since you have type checking now.

export class Foo { }

//'Foo' needs to be the class name. The import will be refactored
//in case of a rename!
import { Foo } from './Foo'

Going forward, the new HTML Intersection Observer API is the thing you're looking for. It allows you to configure a callback that is called whenever one element, called the target, intersects either the device viewport or a specified element. It's available in latest versions of Chrome, Firefox and Edge. See https://developer.mozilla.org/en-US/docs/Web/API/Intersection_Observer_API for more info.

Simple code example for observing display:none switching:

// Start observing visbility of element. On change, the
//   the callback is called with Boolean visibility as
//   argument:

function respondToVisibility(element, callback) {
  var options = {
    root: document.documentElement,
  };

  var observer = new IntersectionObserver((entries, observer) => {
    entries.forEach(entry => {
      callback(entry.intersectionRatio > 0);
    });
  }, options);

  observer.observe(element);
}

If you have more than one key you may need to do ssh-add private-keyfile

I might suggest the apache commons project. This project already provides a framework for doing what you need (i.e. flexible filtering of collections).

(repost from my other response)
Use cli utility keytool from java software distribution for import (and trust!) needed certificates

Sample:

0. From cli change dir to jre\bin

1. Check keystore (file found in jre\bin directory)
   keytool -list -keystore ..\lib\security\cacerts
   Password is changeit

2. Download and save all certificates in chain from needed server.

3. Add certificates (before need to remove "read-only" attribute on file ..\lib\security\cacerts), run:

   keytool -alias REPLACE_TO_ANY_UNIQ_NAME -import -keystore.\lib\security\cacerts -file "r:\root.crt"

accidentally I found such a simple tip. Other solutions require the use of InstallCert.Java and JDK

The below code stores the return value in to the variable retVal and then MsgBox can be used to display the value:

Dim retVal As Integer
retVal = test()
Msgbox retVal

Since the question didn't specify .NET, this should work in VBScript or VB6.

I have choose @akai version of @timwolla answer and added stopAnimation function in return, so before starting new animation, the old one can be stopped.

if ( this.stopAnimation )
    this.stopAnimation()

    this.stopAnimation = scrollTo( el, scrollDestination, 300 )


// definitions

function scrollTo(element, to, duration) {
    var start = element.scrollTop,
        change = to - start,
        increment = 20,
        timeOut;

    var animateScroll = function(elapsedTime) {        
        elapsedTime += increment;
        var position = easeInOut(elapsedTime, start, change, duration);                        
        element.scrollTop = position; 
        if (elapsedTime < duration) {
            timeOut = setTimeout(function() {
                animateScroll(elapsedTime);
            }, increment);
        }
    };

    animateScroll(0);

    return stopAnimation

    function stopAnimation() {
        clearTimeout( timeOut )
    }
}

function easeInOut(currentTime, start, change, duration) {
    currentTime /= duration / 2;
    if (currentTime < 1) {
        return change / 2 * currentTime * currentTime + start;
    }
    currentTime -= 1;
    return -change / 2 * (currentTime * (currentTime - 2) - 1) + start;

Old question but anyway !

Same thing happen to me this morning, everything was working fine for weeks before...... yes guess what ... I change my windows PC user account password yesterday night !!!!! (how stupid was I !!!)

So easy fix : IIS -> authentication -> Anonymous authentication -> edit and set the user and new PASSWORD !!!!!

Also try System.currentTimeMillis()

I'll rename the function take_closest to conform with PEP8 naming conventions.

If you mean quick-to-execute as opposed to quick-to-write, min should not be your weapon of choice, except in one very narrow use case. The min solution needs to examine every number in the list and do a calculation for each number. Using bisect.bisect_left instead is almost always faster.

The "almost" comes from the fact that bisect_left requires the list to be sorted to work. Hopefully, your use case is such that you can sort the list once and then leave it alone. Even if not, as long as you don't need to sort before every time you call take_closest, the bisect module will likely come out on top. If you're in doubt, try both and look at the real-world difference.

from bisect import bisect_left

def take_closest(myList, myNumber):
    """
    Assumes myList is sorted. Returns closest value to myNumber.

    If two numbers are equally close, return the smallest number.
    """
    pos = bisect_left(myList, myNumber)
    if pos == 0:
        return myList[0]
    if pos == len(myList):
        return myList[-1]
    before = myList[pos - 1]
    after = myList[pos]
    if after - myNumber < myNumber - before:
       return after
    else:
       return before

Bisect works by repeatedly halving a list and finding out which half myNumber has to be in by looking at the middle value. This means it has a running time of O(log n) as opposed to the O(n) running time of the highest voted answer. If we compare the two methods and supply both with a sorted myList, these are the results:

$ python -m timeit -s "
from closest import take_closest
from random import randint
a = range(-1000, 1000, 10)" "take_closest(a, randint(-1100, 1100))"

100000 loops, best of 3: 2.22 usec per loop

$ python -m timeit -s "
from closest import with_min
from random import randint
a = range(-1000, 1000, 10)" "with_min(a, randint(-1100, 1100))"

10000 loops, best of 3: 43.9 usec per loop

So in this particular test, bisect is almost 20 times faster. For longer lists, the difference will be greater.

What if we level the playing field by removing the precondition that myList must be sorted? Let's say we sort a copy of the list every time take_closest is called, while leaving the min solution unaltered. Using the 200-item list in the above test, the bisect solution is still the fastest, though only by about 30%.

This is a strange result, considering that the sorting step is O(n log(n))! The only reason min is still losing is that the sorting is done in highly optimalized c code, while min has to plod along calling a lambda function for every item. As myList grows in size, the min solution will eventually be faster. Note that we had to stack everything in its favour for the min solution to win.

I too had the same problem.
Mine was a case where i was using a background image which was in drawables.That particular image was of approx 130kB and was used during splash screen and home page in my android app.

Solution - I just shifted that particular image to drawables-xxx folder from drawables and was able free a lot of memory occupied in background and the skipping frames were no longer skipping.

Update Use 'nodp' drawable resource folder for storing background drawables files.
Will a density qualified drawable folder or drawable-nodpi take precedence?

controller:

use App\your_model_name;
funtion index()
{
$post = your_model_name::all();
return view('index')->with('this_will_be_used_as_variable_in_views',$post);
}

index:

<h1> posts</h1>
@if(count($this_will_be_used_as_variable_in_views)>0)
@foreach($this_will_be_used_as_variable_in_views as $any_variable)
<ul>
<p> {{$any_variable->enter_table_field}} </p>
 <p> {{$any_variable->created_at}} </p>
</ul>

@endforeach
@else
<p> empty </p>
@endif

Hope this helps! :)

I've heard Joseph's Myers implementation is quite fast. Additionally, he has a lengthy article on Javascript optimization describing what he learned while writing his implementation. It's a good read for anyone interested in performant javascript.

http://www.webreference.com/programming/javascript/jkm3/

His MD5 implementation can be found here

There's more to this than meets the eye. Most other answers are correct BUT ALSO..

new Array(n)

• Allows engine to reallocates space for n elements
• Optimized for array creation
• Created array is marked sparse which has the least performant array operations, that's because each index access has to check bounds, see if value exists and walk the prototype chain
• If array is marked as sparse, there's no way back (at least in V8), it'll always be slower during its lifetime, even if you fill it up with content (packed array) 1ms or 2 hours later, doesn't matter

[1, 2, 3] || []

• Created array is marked packed (unless you use delete or [1,,3] syntax)
• Optimized for array operations (for .., forEach, map, etc)
• Engine needs to reallocate space as the array grows

This probably isn't the case for older browser versions/browsers.

I don't believe search and replace will do it for you (doesn't work for me in Excel 2010 Home). Are you sure you want to put "null" in EVERY cell in the sheet? That is millions of cells, in which case there is no way a search and replace would be able to handle it memory-wise (correct me if I am wrong).

In the case I am right and you don't want millions of "null" cells, then here is a macro. It asks you to select the range then put "null" inside every cell that was blank.

Sub FillWithNull()

Dim cell As range
Dim myRange As range

Set myRange = Application.InputBox("Select the range", Type:=8)
Application.ScreenUpdating = False

For Each cell In myRange
    If Len(cell) = 0 Then
        cell.Value = "Null"
    End If
Next

Application.ScreenUpdating = True

End Sub

To be sure, you need to not only replace the single quotes, but as well the already escaped ones:

"first ' and \' second".replace(/'|\\'/g, "\\'")

I had the same problem today. I needed to set a flag in a nmake Makefile if the cl compiler version is 15. Here is the hack I came up with:

!IF ([cl /? 2>&1 | findstr /C:"Version 15" > nul] == 0)
FLAG = "cl version 15"
!ENDIF

Note that cl /? prints the version information to the standard error stream and the help text to the standard output. To be able to check the version with the findstr command one must first redirect stderr to stdout using 2>&1.

The above idea can be used to write a Windows batch file that checks if the cl compiler version is <= a given number. Here is the code of cl_version_LE.bat:

@echo off
FOR /L %%G IN (10,1,%1) DO cl /? 2>&1 | findstr /C:"Version %%G" > nul && goto FOUND
EXIT /B 0
:FOUND
EXIT /B 1

Now if you want to set a flag in your nmake Makefile if the cl version <= 15, you can use:

!IF [cl_version_LE.bat 15]
FLAG = "cl version <= 15"
!ENDIF

A hacky way of doing JSON_UNESCAPED_UNICODE in PHP 5.3. Really disappointed by PHP json support. Maybe this will help someone else.

$array = some_json();
// Encode all string children in the array to html entities.
array_walk_recursive($array, function(&$item, $key) {
    if(is_string($item)) {
        $item = htmlentities($item);
    }
});
$json = json_encode($array);

// Decode the html entities and end up with unicode again.
$json = html_entity_decode($rson);

I Changed Sid Value to orcl, it works fine and connection established

Being consistent is important, but this is the question to ask yourself: "Do I have a constructor for anything else?"

Typically, I am creating models for data transfers that the class itself does nothing except work as housing for variables.

In these scenarios, I usually don't have any methods or constructors. It would feel silly to me to create a constructor for the exclusive purpose of initializing my lists, especially since I can initialize them in-line with the declaration.

So as many others have said, it depends on your usage. Keep it simple, and don't make anything extra that you don't have to.

I just used a snippet of jquery to solve this problem.

$("input[data-val-length-max]").each(function (index, element) {
   var length = parseInt($(this).attr("data-val-length-max"));
   $(this).prop("maxlength", length);
});

The selector finds all of the elements that have a data-val-length-max attribute set. This is the attribute that the StringLength validation attribute will set.

The each loop loops through these matches and will parse out the value for this attribute and assign it to the mxlength property that should have been set.

Just add this to you document ready function and you are good to go.

Here we go,

DataSet ds = new DataSet();
SqlCommand cmd = new SqlCommand();
cmd.Connection = con; //database connection
cmd.CommandText = "WRITE_STORED_PROC_NAME"; //  Stored procedure name
cmd.CommandType = CommandType.StoredProcedure; // set it to stored proc
//add parameter if necessary
cmd.Parameters.Add("@userId", SqlDbType.Int).Value = courseid;

SqlDataAdapter adap = new SqlDataAdapter(cmd);
adap.Fill(ds, "Course");
return ds;

I would suggest the following:

String[] parsedInput = str.split("\n"); String firstName = parsedInput[0].split(": ")[1]; String lastName = parsedInput[1].split(": ")[1]; myMap.put(firstName,lastName); 

Swift 3 version

extension UIView {
    enum ViewSide {
        case Top, Bottom, Left, Right
    }

    func addBorder(toSide side: ViewSide, withColor color: UIColor, andThickness thickness: CGFloat) {

        let border = CALayer()
        border.backgroundColor = color.cgColor

        switch side {
        case .Top:
            border.frame = CGRect(x: 0, y: 0, width: frame.size.width, height: thickness)
        case .Bottom:
            border.frame = CGRect(x: 0, y: frame.size.height - thickness, width: frame.size.width, height: thickness)
        case .Left:
            border.frame = CGRect(x: 0, y: 0, width: thickness, height: frame.size.height)
        case .Right:
            border.frame = CGRect(x: frame.size.width - thickness, y: 0, width: thickness, height: frame.size.height)
        }

        layer.addSublayer(border)
    }
}

In order to set corresponding border you should override viewDidLayoutSubviews() method:

override func viewDidLayoutSubviews() {
    super.viewDidLayoutSubviews()
    yourView.addBorder(toSide: UIView.ViewSide.Top, withColor: UIColor.lightGray, andThickness: 1)

Posting new answer since Angular behavior has changed. Checking equality with undefined now works in angular expressions, at least as of 1.5, as the following code works:

ng-if="foo !== undefined"

When this ng-if evaluates to true, deleting the percentages property off the appropriate scope and calling $digest removes the element from the document, as you would expect.

I usually do it this way...

#include <string>
#include <vector>

int main( int argc, char* argv[] )
{
    std::vector<char> vec;
    //... do something with vec
    std::string str(vec.begin(), vec.end());
    //... do something with str
    return 0;
}

May be this time stamp fit you better Code

Function LastInputTimeStamp() As Date
  LastInputTimeStamp = Now()
End Function

and each time you input data in defined cell (in my example below it is cell C36) you'll get a new constant time stamp. As an example in Excel file may use this

=IF(C36>0,LastInputTimeStamp(),"")

I have a simple solution, that works in postgresql at least, using like any followed by the list of regex. Here is an example, looking at identifying some antibiotics in a list:

select *
from database.table
where lower(drug_name) like any ('{%cillin%,%cyclin%,%xacin%,%mycine%,%cephal%}')

The easiest solution is to simply style the element you're inserting the text into with the following CSS property:

white-space: pre-wrap;

This property causes whitespace and newlines within the matching elements to be treated in the same way as inside a <textarea>. That is, consecutive whitespace is not collapsed, and lines are broken at explicit newlines (but are also wrapped automatically if they exceed the width of the element).

Given that several of the answers posted here so far have been vulnerable to HTML injection (e.g. because they assign unescaped user input to innerHTML) or otherwise buggy, let me give an example of how to do this safely and correctly, based on your original code:

document.getElementById('post-button').addEventListener('click', function () {_x000D_
  var post = document.createElement('p');_x000D_
  var postText = document.getElementById('post-text').value;_x000D_
  post.append(postText);_x000D_
  var card = document.createElement('div');_x000D_
  card.append(post);_x000D_
  var cardStack = document.getElementById('card-stack');_x000D_
  cardStack.prepend(card);_x000D_
});

#card-stack p {_x000D_
  background: #ddd;_x000D_
  white-space: pre-wrap;  /* <-- THIS PRESERVES THE LINE BREAKS */_x000D_
}_x000D_
textarea {_x000D_
  width: 100%;_x000D_
}

<input type="button" id="post-button" value="Post!">_x000D_
<div id="card-stack"></div>

Note that, like your original code, the snippet above uses append() and prepend(). As of this writing, those functions are still considered experimental and not fully supported by all browsers. If you want to be safe and remain compatible with older browsers, you can substitute them pretty easily as follows:

• element.append(otherElement) can be replaced with element.appendChild(otherElement);
• element.prepend(otherElement) can be replaced with element.insertBefore(otherElement, element.firstChild);
• element.append(stringOfText) can be replaced with element.appendChild(document.createTextNode(stringOfText));
• element.prepend(stringOfText) can be replaced with element.insertBefore(document.createTextNode(stringOfText), element.firstChild);
• as a special case, if element is empty, both element.append(stringOfText) and element.prepend(stringOfText) can simply be replaced with element.textContent = stringOfText.

Here's the same snippet as above, but without using append() or prepend():

document.getElementById('post-button').addEventListener('click', function () {_x000D_
  var post = document.createElement('p');_x000D_
  var postText = document.getElementById('post-text').value;_x000D_
  post.textContent = postText;_x000D_
  var card = document.createElement('div');_x000D_
  card.appendChild(post);_x000D_
  var cardStack = document.getElementById('card-stack');_x000D_
  cardStack.insertBefore(card, cardStack.firstChild);_x000D_
});

#card-stack p {_x000D_
  background: #ddd;_x000D_
  white-space: pre-wrap;  /* <-- THIS PRESERVES THE LINE BREAKS */_x000D_
}_x000D_

<input type="button" id="post-button" value="Post!">_x000D_
<div id="card-stack"></div>

Ps. If you really want to do this without using the CSS white-space property, an alternative solution would be to explicitly replace any newline characters in the text with <br> HTML tags. The tricky part is that, to avoid introducing subtle bugs and potential security holes, you have to first escape any HTML metacharacters (at a minimum, & and <) in the text before you do this replacement.

Probably the simplest and safest way to do that is to let the browser handle the HTML-escaping for you, like this:

var post = document.createElement('p');
post.textContent = postText;
post.innerHTML = post.innerHTML.replace(/\n/g, '<br>\n');

document.getElementById('post-button').addEventListener('click', function () {_x000D_
  var post = document.createElement('p');_x000D_
  var postText = document.getElementById('post-text').value;_x000D_
  post.textContent = postText;_x000D_
  post.innerHTML = post.innerHTML.replace(/\n/g, '<br>\n');  // <-- THIS FIXES THE LINE BREAKS_x000D_
  var card = document.createElement('div');_x000D_
  card.appendChild(post);_x000D_
  var cardStack = document.getElementById('card-stack');_x000D_
  cardStack.insertBefore(card, cardStack.firstChild);_x000D_
});

#card-stack p {_x000D_
  background: #ddd;_x000D_
}_x000D_
textarea {_x000D_
  width: 100%;_x000D_
}

<textarea id="post-text" class="form-control" rows="8" placeholder="What's up?" required>Group Schedule:_x000D_

Note that, while this will fix the line breaks, it won't prevent consecutive whitespace from being collapsed by the HTML renderer. It's possible to (sort of) emulate that by replacing some of the whitespace in the text with non-breaking spaces, but honestly, that's getting rather complicated for something that can be trivially solved with a single line of CSS.

I thought about this very often during my PhD (in computer science). I came up with multiple solutions, depending on the ability to distinguish socks and thus find correct pairs as fast as possible.

Suppose the cost of looking at socks and memorizing their distinctive patterns is negligible (e). Then the best solution is simply to throw all socks on a table. This involves those steps:

1. Throw all socks on a table (1) and create a hashmap {pattern: position} (e)
2. While there are remaining socks (n/2):
   1. Pick up one random sock (1)
   2. Find position of corresponding sock (e)
   3. Retrieve sock (1) and store pair

This is indeed the fastest possibility and is executed in n + 1 = O(n) complexity. But it supposes that you perfectly remember all patterns... In practice, this is not the case, and my personal experience is that you sometimes don't find the matching pair at first attempt:

1. Throw all socks on a table (1)
2. While there are remaining socks (n/2):
   1. Pick up one random sock (1)
   2. while it is not paired (1/P):
      1. Find sock with similar pattern
      2. Take sock and compare both (1)
      3. If ok, store pair

This now depends on our ability to find matching pairs. This is particularly true if you have dark/grey pairs or white sports socks that often have very similar patterns! Let's admit that you have a probability of P of finding the corresponding sock. You'll need, on average, 1/P tries before finding the corresponding sock to form a pair. The overall complexity is 1 + (n/2) * (1 + 1/P) = O(n).

Both are linear in the number of socks and are very similar solutions. Let's slightly modify the problem and admit you have multiple pairs of similar socks in the set, and that it is easy to store multiple pairs of socks in one move (1+e). For K distinct patterns, you may implement:

1. For each sock (n):
   1. Pick up one random sock (1)
   2. Put it on its pattern's cluster
2. For each cluster (K):
   1. Take cluster and store pairs of socks (1+e)

The overall complexity becomes n+K = O(n). It is still linear, but choosing the correct algorithm may now greatly depend on the values of P and K! But one may object again that you may have difficulties to find (or create) cluster for each sock.

Besides, you may also loose time by looking on websites what is the best algorithm and proposing your own solution :)

I was working on a small project that required a sub-string counter. Searching for the wrong phrases provided me with no results, however after writing my own implementation I have stumbled upon this question. Anyway, here is my way, it is probably slower than most here but might be helpful to someone:

function count_letters() {
var counter = 0;

for (var i = 0; i < input.length; i++) {
    var index_of_sub = input.indexOf(input_letter, i);

    if (index_of_sub > -1) {
        counter++;
        i = index_of_sub;
    }
}

Please let me know if you find this implementation to fail or do not follow some standards! :)

UPDATE You may want to substitute:

    for (var i = 0; i < input.length; i++) {

With:

for (var i = 0, input_length = input.length; i < input_length; i++) {

Interesting read discussing the above: http://www.erichynds.com/blog/javascript-length-property-is-a-stored-value

Instead of getting IMEI from TelephonyManager use ANDROID_ID.

Settings.Secure.ANDROID_ID

This works for each android device irrespective of having telephony.

I know this is old, but I would like to suggest using a linear-gradient to achieve the same effect instead of margin offset. This is will maintain any content at its original place.

<ul>
    <li><a href="#">One</a></li>
    <li><a href="#">Two</a></li>
    <li><a href="#">Three</a></li>

ul, li, a {
    margin: 0; padding: 0;

/* nav stuff */
ul, li, a {
    display: inline-block;
    text-align: center;

    /* hacks to make one side slant only */
    overflow: hidden;
    background: linear-gradient(to right, red, white, white, red);

I don't see a compelling reason to override onResume or onStart to set the width and height of the Window within DialogFragment's Dialog -- these particular lifecycle methods can get called repeatedly and unnecessarily execute that resizing code more than once due to things like multi window switching, backgrounding then foregrounding the app, and so on. The consequences of that repetition are fairly trivial, but why settle for that?

Setting the width/height instead within an overridden onActivityCreated() method will be an improvement because this method realistically only gets called once per instance of your DialogFragment. For example:

@Override
public void onActivityCreated(Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);

    Window window = getDialog().getWindow();
    assert window != null;

    WindowManager.LayoutParams layoutParams = window.getAttributes();
    layoutParams.width = ViewGroup.LayoutParams.MATCH_PARENT;
    window.setAttributes(layoutParams);
}

Above I just set the width to be match_parent irrespective of device orientation. If you want your landscape dialog to not be so wide, you can do a check of whether getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT beforehand.

I use VS 2017. By default SQL Server Instance name is (LocalDB)\MSSQLLocalDB. However, downgrading the compatibility level of the database to 110 as in @user3390927's answer, I could attach the database file in VS, choosing Server Name as "localhost\SQLExpress".

Your example is perfect: the field is private and it has a getter. This is the normal way to access a field. If you need a direct access to an object field, use reflection. Using reflection to get a field's value is a hack and should be used in extreme cases such as using a library whose code you cannot change.

I was in the same place as you, finally I found a neat answer :

<form action="xx/xx" method="POST">
  <input type="hidden" name="what you want" value="what you want">
  <input type="image" src="xx.xx">
</form>

The right way to do this is:

composer remove jenssegers/mongodb --update-with-dependencies

I must admit the flag here is not quite obvious as to what it will do.

Update

composer remove jenssegers/mongodb

As of v1.0.0-beta2 --update-with-dependencies is the default and is no longer required.

So many answers.... all bad!

Regular expressions don't have an AND operator, so it's pretty hard to write a regex that matches valid passwords, when validity is defined by something AND something else AND something else...

But, regular expressions do have an OR operator, so just apply DeMorgan's theorem, and write a regex that matches invalid passwords.

anything with less than 8 characters OR anything with no numbers OR anything with no uppercase OR anything with no special characters

So:

^(.{0,7}|[^0-9]*|[^A-Z]*|[a-zA-Z0-9]*)$

If anything matches that, then it's an invalid password.

i know i'm years late xD but Here's how i did it

    public static string convertDataTableToString(DataTable dataTable)
    {
        string data = string.Empty;
        for (int i = 0; i < dataTable.Rows.Count; i++)
        {
            DataRow row = dataTable.Rows[i];
            for (int j = 0; j < dataTable.Columns.Count; j++)
            {
                data += dataTable.Columns[j].ColumnName + "~" + row[j];
                if (j == dataTable.Columns.Count - 1)
                {
                    if (i != (dataTable.Rows.Count - 1))
                        data += "$";
                }
                else
                    data += "|";
            }
        }
        return data;
    }

If someone ever optimizes this please let me know

i tried this :

    public static string convertDataTableToString(DataTable dataTable)
    {
        string data = string.Empty;
        int rowsCount = dataTable.Rows.Count;
        for (int i = 0; i < rowsCount; i++)
        {
            DataRow row = dataTable.Rows[i];
            int columnsCount = dataTable.Columns.Count;
            for (int j = 0; j < columnsCount; j++)
            {
                data += dataTable.Columns[j].ColumnName + "~" + row[j];
                if (j == columnsCount - 1)
                {
                    if (i != (rowsCount - 1))
                        data += "$";
                }
                else
                    data += "|";
            }
        }
        return data;
    }

but this answer says it's worse

I found a super simple solution using

<input type="text" inputmode="numeric" />

This is supported is most browsers: https://developer.mozilla.org/en-US/docs/Web/HTML/Global_attributes/inputmode

Found a site on google explaining some changes, according to the author of the page fb does not allow custom buttons. Heres the website.

Unfortunately, it’s against Facebook’s developer policies, which state:

You must not circumvent our intended limitations on core Facebook features.

The Facebook Connect button is intended to be rendered in FBML, which means it’s only meant to look the way Facebook lets it.

Oracle, PostgreSQL, SQL Server and many more RDBMS engines have analytic functions called LAG and LEAD that do this very thing.

In SQL Server prior to 2012 you'd need to do the following:

SELECT  value - (
        SELECT  TOP 1 value
        FROM    mytable m2
        WHERE   m2.col1 < m1.col1 OR (m2.col1 = m1.col1 AND m2.pk < m1.pk)
        ORDER BY 
                col1, pk
        )
FROM mytable m1
ORDER BY
      col1, pk

, where COL1 is the column you are ordering by.

Having an index on (COL1, PK) will greatly improve this query.

Another possible solution that we can use 2 HTML element to store brief and complete text. Hence we can show/hide appropriate HTML element :-)

<p class="content_description" id="brief_description" style="display: block;"> blah blah blah blah blah  </p><p class="content_description" id="complete_description" style="display: none;"> blah blah blah blah blah with complete text </p>

/* jQuery code to toggle both paragraph. */

(function(){
        $('#toggle_content').on(
                'click', function(){
                                $("#complete_description").toggle();
                                $("#brief_description").toggle();
                                if ($("#complete_description").css("display") == "none") {
                                    $(this).text('More...');
                                }   else{
                                    $(this).text('Less...');
                                }
                        }
                );
    })();
