As noted by @mastablasta, but also to add that if you call the 'done' argument or rather name it completed you just call the callback completed() in your test when it's done.

// this block signature will trigger async behavior.
it("should work", function(done){
  // do stuff and then call done...
  done();
});

// this block signature will run synchronously
it("should work", function(){
  //...
});

Text wrapping is not part of SVG1.1, the currently implemented spec. You should rather use HTML via the <foreignObject/> element.

<svg ...>

<switch>
<foreignObject x="20" y="90" width="150" height="200">
<p xmlns="http://www.w3.org/1999/xhtml">Text goes here</p>
</foreignObject>

<text x="20" y="20">Your SVG viewer cannot display html.</text>
</switch>

</svg>

Well as the stack trace says, you would need to set the protected mode settings to same for all zones in IE. Read the why here : http://jimevansmusic.blogspot.in/2012/08/youre-doing-it-wrong-protected-mode-and.html

and a quick how to from the same link : "In IE, from the Tools menu (or the gear icon in the toolbar in later versions), select "Internet options." Go to the Security tab. At the bottom of the dialog for each zone, you should see a check box labeled "Enable Protected Mode." Set the value of the check box to the same value, either checked or unchecked, for each zone"

Here we go... just copy the code to a module, it's ready to use

Here's a version that doesn't fail if log.txt is missing:

@echo off
  if not exist log.txt goto firstlogin
  echo Date/Time last login:

            System.Text.ASCIIEncoding.ASCII.GetBytes(
               $"{yourusername}:{yourpwd}")));

In Java reading and writing fields of all types except long and double occurs atomically, and if the field is declared with the volatile modifier, even long and double are atomically read and written. That is, we get 100% either what was there, or what happened there, nor can there be any intermediate result in the variables.

use

$(this).cssUnit('marginBottom');

which return an array. first index returns margin bottom's value(example 20 for 20px) and second index returns margin bottom's unit(example px for 20px)

One more variant using extension and argument name range

This extension uses Range and ClosedRange

extension Array {

    subscript (range r: Range<Int>) -> Array {
        return Array(self[r])
    }


    subscript (range r: ClosedRange<Int>) -> Array {
        return Array(self[r])
    }
}

Tests:

func testArraySubscriptRange() {
    //given
    let arr = ["1", "2", "3"]

    //when
    let result = arr[range: 1..<arr.count] as Array

    //then
    XCTAssertEqual(["2", "3"], result)
}

func testArraySubscriptClosedRange() {
    //given
    let arr = ["1", "2", "3"]

    //when
    let result = arr[range: 1...arr.count - 1] as Array

    //then
    XCTAssertEqual(["2", "3"], result)
}

For Mac:

Quick Text Search: Shift + Cmd + L

All other search (like File Search, Git Search, Java Search etc): Ctrl + H

break x if ((int)strcmp(y, "hello")) == 0

On some implementations gdb might not know the return type of strcmp. That means you would have to cast, otherwise it would always evaluate to true!

Bootstrap 3

Try this. Simple solution with no dependencies.

$('[data-toggle="collapse"]').click(function() {
  $('.collapse.in').collapse('hide')
});

I remember one time when I stumbled upon this issue a few years ago, it's because windows don't have readline, therefore no interactive shell, to use php interactive mode without readline support, you can do this instead:

C:\>php -a 
Interactive mode enabled 

<?php 
echo "Hello, world!"; 
?> 
^Z 
Hello, world!

After entering interactive mode, type using opening (<?php) and closing (?>) php tag, and end with control Z (^Z) which denotes the end of file.

I also recall that I found the solution from php's site user comment: http://www.php.net/manual/en/features.commandline.interactive.php#105729

set the height to 200

Set the Font to a large variant (150+ px). As already mentioned, control the width using columns, and use a layout manager (or constraint) that will respect the preferred width & height.

1. Download the file from http://www.java2s.com/Code/Jar/STUVWXYZ/Downloadjavaxservletjar.htm

2. Make a folder ("lib") inside the project folder and move that jar file to there.

3. In Eclipse, right click on project > BuildPath > Configure BuildPath > Libraries > Add External Jar

Thats all

I don't have a unix system under my hands, but try this:

count7=$((${count7} + ${count1}))

Or maybe you have a shell that doesn't support this expression. I think bash does support it, but sh doesn't.

EDIT: There is another syntax, try:

count7=`expr $count7 + $count1`

If you have access to a linux box with mdbtools installed, you can use this Bash shell script (save as mdbconvert.sh):

#!/bin/bash

TABLES=$(mdb-tables -1 $1)

MUSER="root"
MPASS="yourpassword"
MDB="$2"

MYSQL=$(which mysql)

for t in $TABLES
do
    $MYSQL -u $MUSER -p$MPASS $MDB -e "DROP TABLE IF EXISTS $t"
done

mdb-schema $1 mysql | $MYSQL -u $MUSER -p$MPASS $MDB

for t in $TABLES
do
    mdb-export -D '%Y-%m-%d %H:%M:%S' -I mysql $1 $t | $MYSQL -u $MUSER -p$MPASS $MDB
done

To invoke it simply call it like this:

./mdbconvert.sh accessfile.mdb mysqldatabasename

It will import all tables and all data.

This problem also arises when you have mockito-all on your class path, which is already deprecated.

If possible just include mockito-core.

Maven config for mixing junit, mockito and hamcrest:

It's not the -- or ++, it is the compare operation. With -- you can use a compare with 0, while with ++ you need to compare it with the length. On the processor, compare with zero is normally available, while compare with a finite integer requires a subtraction.

a++ < length

is actually compiled as

a++
test (a-length)

So it takes longer on the processor when compiled.

ffmpeg provides this functionality. All you need to do is run someting like

ffmpeg -i <inputfilename> -s 640x480 -b 512k -vcodec mpeg1video -acodec copy <outputfilename>

For newer versions of ffmpeg you need to change -b to -b:v:

ffmpeg -i <inputfilename> -s 640x480 -b:v 512k -vcodec mpeg1video -acodec copy <outputfilename>

to convert the input video file to a video with a size of 640 x 480 and a bitrate of 512 kilobits/sec using the MPEG 1 video codec and just copying the original audio stream. Of course, you can plug in any values you need and play around with the size and bitrate to achieve the quality/size tradeoff you are looking for. There are also a ton of other options described in the documentation

Run ffmpeg -formats or ffmpeg -codecs for a list of all of the available formats and codecs. If you don't have to target a specific codec for the final output, you can achieve better compression ratios with minimal quality loss using a state of the art codec like H.264.

In Jelly.core to test a literal string one would use:

<core:when test="${ name == 'ABC' }"> 

But if I have to check for string "Toy's R Us":

<core:when test="${ name == "Toy's R Us" }">

It would be like this, if the double quotes were allowed inside:

<core:when test="${ name == "Toy's R Us" }"> 

You could club find with exec as follows to get the list of the files as well as the occurrence of the word/string that you are looking for

find . -exec grep "my word" '{}' \; -print

There are three packagers, and two compilers:

free packager: PAR
commercial packagers: perl2exe, perlapp
compilers: B::C, B::CC

http://search.cpan.org/dist/B-C/perlcompile.pod

(Note: perlfaq3 is still wrong)

For strawberry you need perl-5.16 and B-C from git master (1.43), as B-C-1.42 does not support 5.16.

Create an S3 client object with your credentials

AWS_S3_CREDS = {
    "aws_access_key_id":"your access key", # os.getenv("AWS_ACCESS_KEY")
    "aws_secret_access_key":"your aws secret key" # os.getenv("AWS_SECRET_KEY")
}
s3_client = boto3.client('s3',**AWS_S3_CREDS)

It is always good to get credentials from os environment

To set Environment variables run the following commands in terminal

if linux or mac

$ export AWS_ACCESS_KEY="aws_access_key"
$ export AWS_SECRET_KEY="aws_secret_key"

if windows

c:System\> set AWS_ACCESS_KEY="aws_access_key"
c:System\> set AWS_SECRET_KEY="aws_secret_key"

In this case, UIButton is derived from UIControl. This works for object derived from UIControl.

I wanted to reuse "UIBarButtonItem" action on specific use case. Here, UIBarButtonItem doesn't offer method sendActionsForControlEvents:

But luckily, UIBarButtonItem has properties for target & action.

 if(notHappy){        
         SEL exit = self.navigationItem.rightBarButtonItem.action;
         id  world = self.navigationItem.rightBarButtonItem.target;
         [world performSelector:exit];
 }

Here, rightBarButtonItem is of type UIBarButtonItem.

All the considerations made by @EdChum in 2014 are still valid, but the pandas.Dataframe.ix method is deprecated from the version 0.0.20 of pandas. Directly from the docs:

Warning: Starting in 0.20.0, the .ix indexer is deprecated, in favor of the more strict .iloc and .loc indexers.

In subsequent versions of pandas, this method has been replaced by new indexing methods pandas.Dataframe.loc and pandas.Dataframe.iloc.

If you want to learn more, in this post you can find comparisons between the methods mentioned above.

Ultimately, to date (and there does not seem to be any change in the upcoming versions of pandas from this point of view), the answer to this question is as follows:

foo = df.loc[(df['column1']==value) | (df['columns2'] == 'b') | (df['column3'] == 'c')]

I got this error on my ubuntu box until I ran eclipse as root and installed from there:

$ gksudo eclipse

Eclipse was trying to download the packages to /usr/lib/* where I don't have write permissions

Modifying styles directly in range or cells did not work for me. But the idea to:

1. create a separate style
2. apply all the necessary style property values
3. set the style's name to the Style property of the range

, given in MSDN How to: Programmatically Apply Styles to Ranges in Workbooks did the job.

For example:

var range = worksheet.Range[string.Format("A{0}:C{0}", rowIndex++)];
range.Merge();
range.Value = "some value";

var style = workbook.AddStyle();
style.HorizontalAlignment = Microsoft.Office.Interop.Excel.XlHAlign.xlHAlignLeft;

range.Style = style.Name;

Please check with the delegate method whether it is correct or not. For example;

-(void) tableView:(UITableView *)tableView didDeselectRowAtIndexPath:(NSIndexPath *)indexPath

for

-(void) tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath

maybe this error came because this version of Sql Server is not installed

connectionString="Data Source=(LocalDB)\v12.0;....

and you don't have to install it

the fastest fix is to change it to any installed version you have

in my case I change it from v12.0 to MSSQLLocalDB

I've discovered that if the filename has 300 in it, AdBlock blocks the page and throws a ERR_BLOCKED_BY_CLIENT error.

No, but browser auto-complete is often triggered by the field having the same name attribute as fields that were previously filled out. If you could rig up a clever way to have a randomized field name, autocomplete wouldn't be able to pull any previously entered values for the field.

If you were to give an input field a name like "email_<?= randomNumber() ?>", and then have the script that receives this data loop through the POST or GET variables looking for something matching the pattern "email_[some number]", you could pull this off, and this would have (practically) guaranteed success, regardless of browser.

Its better to build ObservableCollection and take advantage of it

public ObservableCollection<string> list = new ObservableCollection<string>();
list.Add("a");
list.Add("b");
list.Add("c");
this.cbx.ItemsSource = list;

cbx is comobobox name

Also Read : Difference between List, ObservableCollection and INotifyPropertyChanged

If you want a histogram, you don't need to attach any 'names' to x-values, as on x-axis you would have data bins:

import matplotlib.pyplot as plt
import numpy as np
%matplotlib inline

np.random.seed(42)
x = np.random.normal(size=1000)

plt.hist(x, density=True, bins=30)  # density=False would make counts
plt.ylabel('Probability')
plt.xlabel('Data');

Note, the number of bins=30 was chosen arbitrarily, and there is Freedman–Diaconis rule to be more scientific in choosing the "right" bin width:

, where IQR is Interquartile range and n is total number of datapoints to plot

So, according to this rule one may calculate number of bins as:

q25, q75 = np.percentile(x,[.25,.75])
bin_width = 2*(q75 - q25)*len(x)**(-1/3)
bins = round((x.max() - x.min())/bin_width)
print("Freedman–Diaconis number of bins:", bins)
plt.hist(x, bins = bins);

Freedman–Diaconis number of bins: 82

And finally you can make your histogram a bit fancier with PDF line, titles, and legend:

import scipy.stats as st

plt.hist(x, density=True, bins=82, label="Data")
mn, mx = plt.xlim()
plt.xlim(mn, mx)
kde_xs = np.linspace(mn, mx, 300)
kde = st.gaussian_kde(x)
plt.plot(kde_xs, kde.pdf(kde_xs), label="PDF")
plt.legend(loc="upper left")
plt.ylabel('Probability')
plt.xlabel('Data')
plt.title("Histogram");

However, if you have limited number of data points, like in OP, a bar plot would make more sense to represent your data. Then you may attach labels to x-axis:

x = np.arange(3)
plt.bar(x, height=[1,2,3])
plt.xticks(x, ['a','b','c'])

select a.id, a.object
from table_A a
inner join table_B b on a.id=b.id
where b.tag = 'chair';

AFAIK JSON.Net does not provide functionality for reading from a URL. So you need to do this in two steps:

using (var webClient = new System.Net.WebClient()) {
    var json = webClient.DownloadString(URL);
    // Now parse with JSON.Net
}

Maybe you mean like this? I like to make an object and use Format-Table:

> $array = @()
> $object = New-Object -TypeName PSObject
> $object | Add-Member -Name 'Name' -MemberType Noteproperty -Value 'Joe'
> $object | Add-Member -Name 'Age' -MemberType Noteproperty -Value 32
> $object | Add-Member -Name 'Info' -MemberType Noteproperty -Value 'something about him'
> $array += $object
> $array | Format-Table

Name                                                                        Age Info
----                                                                        --- ----
Joe                                                                          32  something about him

This will put all objects you have in the array in columns according to their properties.

Tip: Using -auto sizes the table better

> $array | Format-Table -Auto

Name Age Info
---- --- ----
Joe   32 something about him

You can also specify which properties you want in the table. Just separate each property name with a comma:

> $array | Format-Table Name, Age -Auto

Name Age
---- ---
Joe   32

you can find custom list adapter class with filterable using text change in edit text...

create custom list adapter class with implementation of Filterable:

private class CustomListAdapter extends BaseAdapter implements Filterable{

    private LayoutInflater inflater;
    private ViewHolder holder;
    private ItemFilter mFilter = new ItemFilter();

    public CustomListAdapter(List<YourCustomData> newlist) {
        filteredData = newlist;
    }

    @Override
    public int getCount() {
        return filteredData.size();
    }

    @Override
    public Object getItem(int position) {
        return null;
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {

        holder = new ViewHolder();

        if(inflater==null)
            inflater = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);

Cygwin uses a DLL, cygwin.dll, (or maybe a set of DLLs) to provide a POSIX-like runtime on Windows.

MinGW compiles to a native Win32 application.

If you build something with Cygwin, any system you install it to will also need the Cygwin DLL(s). A MinGW application does not need any special runtime.

You could add it between your <head></head> tag like so:

<head>
  <link href="./node_modules/font-awesome/css/font-awesome.css" rel="stylesheet" type="text/css">
</head>

Or whatever your path to your node_modules is.

Edit (2017-06-26) - Disclaimer: THERE ARE BETTER ANSWERS. PLEASE DO NOT USE THIS METHOD. At the time of this original answer, good tools weren't as prevalent. With current build tools such as webpack or browserify, it probably doesn't make sense to use this answer. I can delete it, but I think it's important to highlight the various options one has and the possible dos and do nots.

The accepted answer detects digits but does not detect formated numbers, e.g. 2,000, nor decimals, e.g. 4.8. For such use -?\\d+(,\\d+)*?\\.?\\d+?:

Pattern p = Pattern.compile("-?\\d+(,\\d+)*?\\.?\\d+?");
List<String> numbers = new ArrayList<String>();
Matcher m = p.matcher("Government has distributed 4.8 million textbooks to 2,000 schools");
while (m.find()) {  
    numbers.add(m.group());
}   
System.out.println(numbers);

Output: [4.8, 2,000]

In addition to everything that's been said already, I'm going to throw in another reason that was a huge pain for us to debug.

Apache 2.4.6 with PHP 5.4 actually segmentation faults on our production machines when there's empty space behind the closing php tag. I just wasted hours until I finally narrowed down the bug with strace.

Here is the error that Apache throws:

[core:notice] [pid 7842] AH00052: child pid 10218 exit signal Segmentation fault (11)

Even though this is an old question, this way of doing it would take of many situations and seems to be robust. You need to have PHP 5.3.0 or above.

$EndDateTime = DateTime::createFromFormat('d/m/Y', "16/07/2017");
$EndDateTime->modify('+6 days');
echo $EndDateTime->format('d/m/Y');

You can have any type of format for the date string and this would work.

First you need to publish the file by:

1. BUILD -> PUBLISH or by right clicking project on Solution Explorer -> properties -> publish or select project in Solution Explorer and press Alt + Enter NOTE: if you are using Visual Studio 2013 then in properties you have to go to BUILD and then you have to disable define DEBUG constant and define TRACE constant and you are ready to go.

2. Save your file to a particular folder. Find the produced files (the EXE file and the .config, .manifest, and .application files, along with any DLL files, etc.) - they are all in the same folder and typically in the bin\Debug folder below the project file (.csproj). In Visual Studio they are in the Application Files folder and inside that you just need the .exe and dll files. (You have to delete ClickOnce and other files and then make this folder a zip file and distribute it.)

NOTE: The ClickOnce application does install the project to system, but it has one advantage. You DO NOT require administrative privileges here to run (if your application follows the normal guidelines for which folders to use for application data, etc.).

This answer is about "how to dynamically create an array without loop".

Literal operator [] doesn't allow us to create dynamically, so let's look into Array, it's constructor and it's methods.

In ES2015 Array has method .from(), which easily allows us to create dynamic Array:

Array.from({length: 10}) // -> [undefined, undefined, undefined, ... ]

When Array's constructor receives number as first parameter, it creates an Array with size of that number, but it is not iterable, so we cannot use .map(), .filter() etc. :

new Array(10) // -> [empty × 10]

But if we'll pass more than one parameter we will receive array from all parameters:

new Array(1,2,3) // -> [1,2,3]

If we would use ES2015 we can use spread operator which will spread empty Array inside another Array, so we will get iterable Array :

[...new Array(10)]  // -> [undefined, undefined, undefined, ...]

But if we don't use ES2015 and don't have polyfills, there is also a way to create dynamic Array without loop in ES5. If we'll think about .apply() method: it spreads second argument array to params. So calling apply on Array's constructor will do the thing:

Array.apply(null, new Array(10))  // -> [undefined, undefined, undefined, ...]

After we have dynamic iterable Array, we can use map to assign dynamic values:

Array.apply(null, new Array(10)).map(function(el, i) {return ++i + ""})

// ["1","2","3", ...]

resource.setrlimit must also be used to increase the stack size and prevent segfault

The Linux kernel limits the stack of processes.

Python stores local variables on the stack of the interpreter, and so recursion takes up stack space of the interpreter.

If the Python interpreter tries to go over the stack limit, the Linux kernel makes it segmentation fault.

The stack limit size is controlled with the getrlimit and setrlimit system calls.

Python offers access to those system calls through the resource module.

sys.setrecursionlimit mentioned e.g. at https://stackoverflow.com/a/3323013/895245 only increases the limit that the Python interpreter self imposes on its own stack size, but it does not touch the limit imposed by the Linux kernel on the Python process.

Example program:

main.py

import resource
import sys

print resource.getrlimit(resource.RLIMIT_STACK)
print sys.getrecursionlimit()
print

# Will segfault without this line.
resource.setrlimit(resource.RLIMIT_STACK, [0x10000000, resource.RLIM_INFINITY])
sys.setrecursionlimit(0x100000)

def f(i):
    print i
    sys.stdout.flush()
    f(i + 1)
f(0)

Of course, if you keep increasing setrlimit, your RAM will eventually run out, which will either slow your computer to a halt due to swap madness, or kill Python via the OOM Killer.

From bash, you can see and set the stack limit (in kb) with:

ulimit -s
ulimit -s 10000

The default value for me is 8Mb.

No, he must have been confused about the MD5 dictionaries.

Here's the Scalatest page on using the runner and the extended discussion on the -t and -z options.

This post shows what commands work for a test file that uses FunSpec.

Here's the test file:

package com.github.mrpowers.scalatest.example

import org.scalatest.FunSpec

class CardiBSpec extends FunSpec {

  describe("realName") {

    it("returns her birth name") {
      assert(CardiB.realName() === "Belcalis Almanzar")
    }

  }

  describe("iLike") {

    it("works with a single argument") {
      assert(CardiB.iLike("dollars") === "I like dollars")
    }

    it("works with multiple arguments") {
      assert(CardiB.iLike("dollars", "diamonds") === "I like dollars, diamonds")
    }

    it("throws an error if an integer argument is supplied") {
      assertThrows[java.lang.IllegalArgumentException]{
        CardiB.iLike()
      }
    }

    it("does not compile with integer arguments") {
      assertDoesNotCompile("""CardiB.iLike(1, 2, 3)""")
    }

  }

}

This command runs the four tests in the iLike describe block (from the SBT command line):

testOnly *CardiBSpec -- -z iLike

You can also use quotation marks, so this will also work:

testOnly *CardiBSpec -- -z "iLike"

This will run a single test:

testOnly *CardiBSpec -- -z "works with multiple arguments"

This will run the two tests that start with "works with":

testOnly *CardiBSpec -- -z "works with"

I can't get the -t option to run any tests in the CardiBSpec file. This command doesn't run any tests:

testOnly *CardiBSpec -- -t "works with multiple arguments"

Looks like the -t option works when tests aren't nested in describe blocks. Let's take a look at another test file:

class CalculatorSpec extends FunSpec {
  it("adds two numbers") {
    assert(Calculator.addNumbers(3, 4) === 7)
  }
}

-t can be used to run the single test:

testOnly *CalculatorSpec -- -t "adds two numbers"

-z can also be used to run the single test:

testOnly *CalculatorSpec -- -z "adds two numbers"

See this repo if you'd like to run these examples. You can find more info on running tests here.

The problem is almost certainly that you're not using the MPI compiler wrappers. Whenever you're compiling an MPI program, you should use the MPI wrappers:

• C - mpicc
• C++ - mpiCC, mpicxx, mpic++
• FORTRAN - mpifort, mpif77, mpif90

These wrappers do all of the dirty work for you of making sure that all of the appropriate compiler flags, libraries, include directories, library directories, etc. are included when you compile your program.

Add this connection string tag in web.config file:

<connectionStrings>
  <add name="itmall" 
    connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=D:\19-02\ABCC\App_Data\abcc.mdf;Integrated Security=True;User Instance=True"/>
</connectionStrings>

And use it like you mentioned. :)

i use jquery code for this. (Alternative solution)

    $(document).ready(function() { 
       var margin = $(".topmenu-design").width()-$("#topmenu").width();
       $("#topmenu").css('margin-left',margin/2);
    });

Alternatively you could update brew by installing it again. (Think I did this as El Capitan changed something)

Note: this is a heavy handed approach that will remove all applications installed via brew!

Try to install brew a fresh and it will tell how to uninstall.

At original time of writing to uninstall:

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

Edit: As of 2020 to uninstall:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall.sh)"

Try tracert to resolve the hostname. IE you have Ip address 8.8.8.8 so you would use; tracert 8.8.8.8

I use Globalize so work with many date formats so use the following:

@Html.TextBoxFor(m => m.DateOfBirth, "{0:d}")

This will automatically adjust the date format to the browser's locale settings.

You need to move your angular app code below the inclusion of the angular libraries. At the time your angular code runs, angular does not exist yet. This is an error (see your dev tools console).

In this line:

var app = angular.module(`

you are attempting to access a variable called angular. Consider what causes that variable to exist. That is found in the angular.js script which must then be included first.

  <h1>{{2+3}}</h1>

  <!-- In production use:
  <script src="//ajax.googleapis.com/ajax/libs/angularjs/1.0.7/angular.min.js"></script>
  -->
  <script src="lib/angular/angular.js"></script>
  <script src="lib/angular/angular-route.js"></script>
  <script src="js/app.js"></script>
  <script src="js/services.js"></script>
  <script src="js/controllers.js"></script>
  <script src="js/filters.js"></script>
  <script src="js/directives.js"></script>

      <script>
        var app = angular.module('myApp',[]);

        app.directive('myDirective',function(){

            return function(scope, element,attrs) {
                element.bind('click',function() {alert('click')});
            };

        });
    </script>

For completeness, it is true that your directive is similar to the already existing directive ng-click, but I believe the point of this exercise is just to practice writing simple directives, so that makes sense.

You can cast the int to an enum

There is also the option of Enum.Parse

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

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

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

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

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

I've written this eval method for arithmetic expressions to answer this question. It does addition, subtraction, multiplication, division, exponentiation (using the ^ symbol), and a few basic functions like sqrt. It supports grouping using (...), and it gets the operator precedence and associativity rules correct.

public static double eval(final String str) {
    return new Object() {
        int pos = -1, ch;

        void nextChar() {
            ch = (++pos < str.length()) ? str.charAt(pos) : -1;
        }

        boolean eat(int charToEat) {
            while (ch == ' ') nextChar();
            if (ch == charToEat) {
                nextChar();
                return true;
            }
            return false;
        }

        double parse() {
            nextChar();
            double x = parseExpression();
            if (pos < str.length()) throw new RuntimeException("Unexpected: " + (char)ch);
            return x;
        }

        // Grammar:
        // expression = term | expression `+` term | expression `-` term
        // term = factor | term `*` factor | term `/` factor
        // factor = `+` factor | `-` factor | `(` expression `)`
        //        | number | functionName factor | factor `^` factor

        double parseExpression() {
            double x = parseTerm();
            for (;;) {
                if      (eat('+')) x += parseTerm(); // addition
                else if (eat('-')) x -= parseTerm(); // subtraction
                else return x;
            }
        }

        double parseTerm() {
            double x = parseFactor();
            for (;;) {
                if      (eat('*')) x *= parseFactor(); // multiplication
                else if (eat('/')) x /= parseFactor(); // division
                else return x;
            }
        }

        double parseFactor() {
            if (eat('+')) return parseFactor(); // unary plus
            if (eat('-')) return -parseFactor(); // unary minus

            double x;
            int startPos = this.pos;
            if (eat('(')) { // parentheses
                x = parseExpression();
                eat(')');
            } else if ((ch >= '0' && ch <= '9') || ch == '.') { // numbers
                while ((ch >= '0' && ch <= '9') || ch == '.') nextChar();
                x = Double.parseDouble(str.substring(startPos, this.pos));
            } else if (ch >= 'a' && ch <= 'z') { // functions
                while (ch >= 'a' && ch <= 'z') nextChar();
                String func = str.substring(startPos, this.pos);
                x = parseFactor();
                if (func.equals("sqrt")) x = Math.sqrt(x);
                else if (func.equals("sin")) x = Math.sin(Math.toRadians(x));
                else if (func.equals("cos")) x = Math.cos(Math.toRadians(x));
                else if (func.equals("tan")) x = Math.tan(Math.toRadians(x));
                else throw new RuntimeException("Unknown function: " + func);
            } else {
                throw new RuntimeException("Unexpected: " + (char)ch);
            }

            if (eat('^')) x = Math.pow(x, parseFactor()); // exponentiation

            return x;
        }
    }.parse();
}

Example:

System.out.println(eval("((4 - 2^3 + 1) * -sqrt(3*3+4*4)) / 2"));

Output: 7.5 (which is correct)

The parser is a recursive descent parser, so internally uses separate parse methods for each level of operator precedence in its grammar. I kept it short so it's easy to modify, but here are some ideas you might want to expand it with:

• Variables:

  The bit of the parser that reads the names for functions can easily be changed to handle custom variables too, by looking up names in a variable table passed to the eval method, such as a Map<String,Double> variables.

• Separate compilation and evaluation:

  What if, having added support for variables, you wanted to evaluate the same expression millions of times with changed variables, without parsing it every time? It's possible. First define an interface to use to evaluate the precompiled expression:

  @FunctionalInterface
  interface Expression {
      double eval();
  }
  

  Now change all the methods that return doubles, so instead they return an instance of that interface. Java 8's lambda syntax works great for this. Example of one of the changed methods:

  Expression parseExpression() {
      Expression x = parseTerm();
      for (;;) {
          if (eat('+')) { // addition
              Expression a = x, b = parseTerm();
              x = (() -> a.eval() + b.eval());
          } else if (eat('-')) { // subtraction
              Expression a = x, b = parseTerm();
              x = (() -> a.eval() - b.eval());
          } else {
              return x;
          }
      }
  }
  

  That builds a recursive tree of Expression objects representing the compiled expression (an abstract syntax tree). Then you can compile it once and evaluate it repeatedly with different values:

  public static void main(String[] args) {
      Map<String,Double> variables = new HashMap<>();
      Expression exp = parse("x^2 - x + 2", variables);
      for (double x = -20; x <= +20; x++) {
          variables.put("x", x);
          System.out.println(x + " => " + exp.eval());
      }
  }
  

• Different datatypes:

  Instead of double, you could change the evaluator to use something more powerful like BigDecimal, or a class that implements complex numbers, or rational numbers (fractions). You could even use Object, allowing some mix of datatypes in expressions, just like a real programming language. :)

After all i got the answer thanks to wikisona, first the beans:

@Bean
public TomcatEmbeddedServletContainerFactory tomcatFactory() {
    return new TomcatEmbeddedServletContainerFactory() {

        @Override
        protected TomcatEmbeddedServletContainer getTomcatEmbeddedServletContainer(
                Tomcat tomcat) {
            tomcat.enableNaming();
            return super.getTomcatEmbeddedServletContainer(tomcat);
        }

        @Override
        protected void postProcessContext(Context context) {
            ContextResource resource = new ContextResource();
            resource.setName("jdbc/myDataSource");
            resource.setType(DataSource.class.getName());
            resource.setProperty("driverClassName", "your.db.Driver");
            resource.setProperty("url", "jdbc:yourDb");

            context.getNamingResources().addResource(resource);
        }
    };
}

@Bean(destroyMethod="")
public DataSource jndiDataSource() throws IllegalArgumentException, NamingException {
    JndiObjectFactoryBean bean = new JndiObjectFactoryBean();
    bean.setJndiName("java:comp/env/jdbc/myDataSource");
    bean.setProxyInterface(DataSource.class);
    bean.setLookupOnStartup(false);
    bean.afterPropertiesSet();
    return (DataSource)bean.getObject();
}

To print stacktrace of Error in console in more readable way:

console.log(ex, ex.stack.split("\n"));

Example result:

[Error] [ 'Error',
  '    at repl:1:7',
  '    at REPLServer.self.eval (repl.js:110:21)',
  '    at Interface.<anonymous> (repl.js:239:12)',
  '    at Interface.EventEmitter.emit (events.js:95:17)',
  '    at Interface._onLine (readline.js:202:10)',
  '    at Interface._line (readline.js:531:8)',

Is just casting the value returned by time()

#include <stdio.h>
#include <time.h>

int main(void) {
    printf("Timestamp: %d\n",(int)time(NULL));
    return 0;
}

what you want?

$ gcc -Wall -Wextra -pedantic -std=c99 tstamp.c && ./a.out
Timestamp: 1343846167

To get microseconds since the epoch, from C11 on, the portable way is to use

int timespec_get(struct timespec *ts, int base)

Unfortunately, C11 is not yet available everywhere, so as of now, the closest to portable is using one of the POSIX functions clock_gettime or gettimeofday (marked obsolete in POSIX.1-2008, which recommends clock_gettime).

The code for both functions is nearly identical:

#include <stdio.h>
#include <time.h>
#include <stdint.h>
#include <inttypes.h>

int main(void) {

    struct timespec tms;

    /* The C11 way */
    /* if (! timespec_get(&tms, TIME_UTC)) { */

    /* POSIX.1-2008 way */
    if (clock_gettime(CLOCK_REALTIME,&tms)) {
        return -1;
    }
    /* seconds, multiplied with 1 million */
    int64_t micros = tms.tv_sec * 1000000;
    /* Add full microseconds */
    micros += tms.tv_nsec/1000;
    /* round up if necessary */
    if (tms.tv_nsec % 1000 >= 500) {
        ++micros;
    }
    printf("Microseconds: %"PRId64"\n",micros);
    return 0;
}

The {glue} package offers string interpolation. In the example, {wd} is substituted with the contents of the variable. Complex expressions are also supported.

library(glue)

wd <- getwd()
glue("Current working dir: {wd}")
#> Current working dir: /tmp/RtmpteMv88/reprex46156826ee8c

For my case with dlib installation into my python [Python 3.6.9], I have found that changing WHL file name from dlib-19.8.1-cp36-cp36m-win_amd64.whl to dlib-19.8.1-cp36-none-any.whl works for me.

Here is the way I run pip install to install dlib:

pip3 install dlib-19.8.1-cp36-none-any.whl

However, I still wonder whether there are any alternatives to install of WHL file by pip command without changing the name.

Use JSON.stringify() to wrap your json

var parameter = JSON.stringify({type:"user", username:user_email, password:user_password});
    $http.post(url, parameter).
    success(function(data, status, headers, config) {
        // this callback will be called asynchronously
        // when the response is available
        console.log(data);
      }).
      error(function(data, status, headers, config) {
        // called asynchronously if an error occurs
        // or server returns response with an error status.
      });

I had similar problem while installing SQL Server 2005 on Windows 7 Professional and got error SQL server failed to start. I logged in as a Administrator (my user id is administrator) in windows.

SOLUTION

1. Go to services, from control panel -> Administrative Tools

2. Click on properties of "SQL Server (MSSQLSERVER)"

3. Go to Log On Tab, Select "This Account"

4. Enter your windows login detail (administrator and password)

5. Start the service manually, it should work fine..

Hope this too helps..

Here is another try:

function stringToColor(str){
  var hash = 0;
  for(var i=0; i < str.length; i++) {
    hash = str.charCodeAt(i) + ((hash << 3) - hash);
  }
  var color = Math.abs(hash).toString(16).substring(0, 6);

  return "#" + '000000'.substring(0, 6 - color.length) + color;
}

This is another way of tackling the problem if you have long strings (like file path names) and you only want to break the strings on certain characters (like slashes). You can insert Unicode Zero Width Space characters just before (or after) the slashes in the HTML.

function sortArrayByArray(array $toSort, array $sortByValuesAsKeys)
{
    $commonKeysInOrder = array_intersect_key(array_flip($sortByValuesAsKeys), $toSort);
    $commonKeysWithValue = array_intersect_key($toSort, $commonKeysInOrder);
    $sorted = array_merge($commonKeysInOrder, $commonKeysWithValue);
    return $sorted;
}

As a rule of thumb, you should build a fat JAR using Maven (a JAR that contains both your code and all dependencies).

Then you can write a Dockerfile that matches your requirements (if you can build a fat JAR you would only need a base os, like CentOS, and the JVM).

This is what I use for a Scala app (which is Java-based).

FROM centos:centos7

# Prerequisites.

RUN yum -y update
RUN yum -y install wget tar

# Oracle Java 7

WORKDIR /opt

RUN wget --no-cookies --no-check-certificate --header "Cookie: gpw_e24=http%3A%2F%2Fwww.oracle.com%2F; oraclelicense=accept-securebackup-cookie" http://download.oracle.com/otn-pub/java/jdk/7u71-b14/server-jre-7u71-linux-x64.tar.gz
RUN tar xzf server-jre-7u71-linux-x64.tar.gz
RUN rm -rf server-jre-7u71-linux-x64.tar.gz
RUN alternatives --install /usr/bin/java java /opt/jdk1.7.0_71/bin/java 1

# App

USER daemon

# This copies to local fat jar inside the image
ADD /local/path/to/packaged/app/appname.jar /app/appname.jar

# What to run when the container starts
ENTRYPOINT [ "java", "-jar", "/app/appname.jar" ]

# Ports used by the app
EXPOSE 5000

This creates a CentOS-based image with Java7. When started, it will execute your app jar.

The best way to deploy it is via the Docker Registry, it's like a Github for Docker images.

You can build an image like this:

# current dir must contain the Dockerfile
docker build -t username/projectname:tagname .

You can then push an image in this way:

docker push username/projectname # this pushes all tags

Once the image is on the Docker Registry, you can pull it from anywhere in the world and run it.

See Docker User Guide for more informations.

Something to keep in mind:

You could also pull your repository inside an image and build the jar as part of the container execution, but it's not a good approach, as the code could change and you might end up using a different version of the app without notice.

Building a fat jar removes this issue.

i post something into an iframe then read back the contents of the iframe with json parse...so sometimes it's not a json string

Try this:

if(response) {
    try {
        a = JSON.parse(response);
    } catch(e) {
        alert(e); // error in the above string (in this case, yes)!
    }
}

If you want the output of your queries to include columns names and be correctly aligned as columns, use these commands in sqlite3:

.headers on
.mode column

You will get output like:

sqlite> .headers on
sqlite> .mode column
sqlite> select * from mytable;
id          foo         bar
----------  ----------  ----------
1           val1        val2
2           val3        val4

Actually the problem seems to me that you are removing elements from the list and expecting to continue to read the list as if nothing had happened.

What you really need to do is to start from the end and back to the begining. Even if you remove elements from the list you will be able to continue reading it.

You need to multiply your Model matrix. Because that is where model position, scaling and rotation should be (that's why it's called the model matrix).

All you need to do is (see here)

Model = glm::rotate(Model, angle_in_radians, glm::vec3(x, y, z)); // where x, y, z is axis of rotation (e.g. 0 1 0)

Note that to convert from degrees to radians, use glm::radians(degrees)

That takes the Model matrix and applies rotation on top of all the operations that are already in there. The other functions translate and scale do the same. That way it's possible to combine many transformations in a single matrix.

note: earlier versions accepted angles in degrees. This is deprecated since 0.9.6

Model = glm::rotate(Model, angle_in_degrees, glm::vec3(x, y, z)); // where x, y, z is axis of rotation (e.g. 0 1 0)

Other answers are correct, especially the one by Jon Skeet, but outdated.

java.time

These old date-time classes have been supplanted by the java.time framework built into Java 8 and later.

If you simply want the current time in UTC, use the Instant class.

Instant now = Instant.now();

EST is not a time zone, as explained in the correct Answer by Jon Skeet. Such 3-4 letter codes are neither standardized nor unique, and further the confusion over Daylight Saving Time (DST). Use a proper time zone name in the "continent/region" format.

Perhaps you meant Eastern Standard Time in east coast of north America? Or Egypt Standard Time? Or European Standard Time?

ZoneId zoneId = ZoneId.of( "America/New_York" );
ZoneId zoneId = ZoneId.of( "Africa/Cairo" );
ZoneId zoneId = ZoneId.of( "Europe/Lisbon" );

Use any such ZoneId object to get the current moment adjusted to a particular time zone to produce a ZonedDateTime object.

ZonedDateTime zdt = ZonedDateTime.now( zoneId ) ;

Adjust that ZonedDateTime into a different time zone by producing another ZonedDateTime object from the first. The java.time framework uses immutable objects rather than changing (mutating) existing objects.

ZonedDateTime zdtGuam = zdt.withZoneSameInstant( ZoneId.of( "Pacific/Guam" ) ) ;

To know the react version, Open package.json file in root folder, search the keywork react. You will see like "react": "^16.4.0",

You should use clock.tick(10) as stated in the docs.

Late but document fragment could be a node:

function hasChild(el){
    var child = el && el.firstChild;
    while (child) {
        if (child.nodeType === 1 || child.nodeType === 11) {
            return true;
        }
        child = child.nextSibling;
    }
    return false;
}
// or
function hasChild(el){
    for (var i = 0; el && el.childNodes[i]; i++) {
        if (el.childNodes[i].nodeType === 1 || el.childNodes[i].nodeType === 11) {
            return true;
        }
    }
    return false;
}

Patching as well Ralph Bolton's answer. Moving to a class and moving tulp of tulp (intervals) to dictionary. Adding an optional rounded function depending of granularity (enable by default). Ready to translation using gettext (default is disable). This is intend to be load from an module. This is for python3 (tested 3.6 - 3.8)

import gettext
import locale
from itertools import chain

mylocale = locale.getdefaultlocale()
# see --> https://stackoverflow.com/a/10174657/11869956 thx 
#localedir = os.path.join(os.path.dirname(__file__), 'locales')
# or python > 3.4:
try:
    localedir = pathlib.Path(__file__).parent/'locales'
    lang_translations = gettext.translation('utils', localedir, 
                                            languages=[mylocale[0]])
    lang_translations.install()
    _ = lang_translations.gettext
except Exception as exc:
    print('Error: unexcept error while initializing translation:', file=sys.stderr)
    print(f'Error: {exc}', file=sys.stderr)
    print(f'Error: localedir={localedir}, languages={mylocale[0]}', file=sys.stderr)
    print('Error: translation has been disabled.', file=sys.stderr)
    _ = gettext.gettext

I have a french translation ready. But it's fast to do the translation ... just few words. Hope this could help as the other answer help me a lot.

If you move the files for whatever reason manually, then Elipse lost the reference and output a missing project file error, but the reason is thaty you move manually the files and Eclipse lost the reference

Its easy go to File - Data Modeler - Import - Data Dictionary - DB connection - OK

In my case I have declared a Bool like this:

var isActivityOpen: Bool 

i.e. I declared it without unwrapping so, This is how I solved the (no initializer) error :

var isActivityOpen: Bool!

The reason is that in your second example i is the word itself, not the index of the word. So

for w1 in words:
     if w1[0] == w1[len(w1) - 1]:
       c += 1
     print c

would the equivalent of your code.

In newer version of git (2.23+) you can use:

git switch -C master origin/master

-C is same as --force-create. Related Reference Docs

It's an argument passed to your success function:

$.ajax({
  type: "POST",
  url: "somescript.php",
  datatype: "html",
  data: dataString,
  success: function(data) {
    alert(data);
    }
});

The full signature is success(data, textStatus, XMLHttpRequest), but you can use just he first argument if it's a simple string coming back. As always, see the docs for a full explanation :)

If your OS is using systemd then you can view docker daemon log with:

sudo journalctl -fu docker.service

This is the error line:

if (called_from.equalsIgnoreCase("add")) {  --->38th error line

This means that called_from is null. Simple check if it is null above:

String called_from = getIntent().getStringExtra("called");

if(called_from == null) {
    called_from = "empty string";
}
if (called_from.equalsIgnoreCase("add")) {
    // do whatever
} else {
    // do whatever
}

That way, if called_from is null, it'll execute the else part of your if statement.

I have used this two function to hide and show view with transition animation smoothly.

        valueAnimator.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
            @Override
            public void onAnimationUpdate(ValueAnimator animation) {
                v.getLayoutParams().height = (int) animation.getAnimatedValue();
                v.requestLayout();
            }
        });
        valueAnimator.setInterpolator(new DecelerateInterpolator());
        valueAnimator.setDuration(duration);
        valueAnimator.start();
        valueAnimator.addListener(new AnimatorListenerAdapter() {

            @Override
            public void onAnimationEnd(Animator animation) {
                v.clearAnimation();
            }
        });

    }

    public void collapse(final View v, int duration, int targetHeight, final int position) {
        if (position == (data.size() - 1)) {

        int prevHeight = v.getHeight();
        ValueAnimator valueAnimator = ValueAnimator.ofInt(prevHeight, targetHeight);

You found one answer, i.e. eval(parse()) . You can also investigate do.call() which is often simpler to implement. Keep in mind the useful as.name() tool as well, for converting strings to variable names.

I would suggest Travis for Open source project. It's just simple to configure and use.

Simple steps to setup:

1. Should have GITHUB account and register in Travis CI website using your GITHUB account.
2. Add .travis.yml file in root of your project. Add Travis as service in your repository settings page.

Now every time you commit into your repository Travis will build your project. You can follow simple steps to get started with Travis CI.

echo "ää" > /tmp/your_file.txt
cat /tmp/your_file.txt | wc -m

results in 3.

In my example the result is expected to be 2 (twice the letter ä). However, echo (or vi) adds a line break \n to the end of the output (or file). So two ä and one Linux line break \n are counted. That's three together.

Working with pipes | is not the shortest variant, but so I have to know less wc parameters by heart. In addition, cat is bullet-proof in my experience.

    Next
End Sub

Use SqlCommand.ExecuteScalar() and cast it to an int:

cmd.CommandText = "SELECT COUNT(*) FROM table_name";
Int32 count = (Int32) cmd.ExecuteScalar();

If you are like me using ubuntu 10.10 & cant find the lastest version which is now

• ruby1.9.3

this is where you can get it http://www.ubuntuupdates.org/package/brightbox_ruby_ng_experimental/maverick/main/base/ruby1.9.3

or download the *.deb file :)

& remember that it wont alter you old version of ruby

Sometimes console will work in IE8/9 but fail at other times. This erratic behaviour depends on whether you have developer tools open and is described in stackoverflow question Does IE9 support console.log, and is it a real function?

fmt.Printf() is fine, but sometimes I like to use pretty print package.

import "github.com/kr/pretty"
pretty.Print(...)

public void Logger(string lines)
{
  //Write the string to a file.append mode is enabled so that the log
  //lines get appended to  test.txt than wiping content and writing the log

  using(System.IO.StreamWriter file = new System.IO.StreamWriter("c:\\test.txt", true))
  {
    file.WriteLine(lines);
  }
}

NOTE: Before trying this code, please find this line in the below code:

private static String DB_NAME ="YourDbName"; // Database name

DB_NAME here is the name of your database. It is assumed that you have a copy of the database in the assets folder, so for example, if your database name is ordersDB, then the value of DB_NAME will be ordersDB,

private static String DB_NAME ="ordersDB";

Keep the database in assets folder and then follow the below:

DataHelper class:

import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

import android.content.Context;
import android.database.SQLException;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteOpenHelper;
import android.util.Log;

public class DataBaseHelper extends SQLiteOpenHelper {

    private static String TAG = "DataBaseHelper"; // Tag just for the LogCat window
    private static String DB_NAME ="YourDbName"; // Database name
    private static int DB_VERSION = 1; // Database version
    private final File DB_FILE;
    private SQLiteDatabase mDataBase;
    private final Context mContext;

    public DataBaseHelper(Context context) {
        super(context, DB_NAME, null, DB_VERSION);
        DB_FILE = context.getDatabasePath(DB_NAME);
        this.mContext = context;
    }

    public void createDataBase() throws IOException {
        // If the database does not exist, copy it from the assets.
        boolean mDataBaseExist = checkDataBase();
        if(!mDataBaseExist) {
            this.getReadableDatabase();
            this.close();
            try {
                // Copy the database from assests
                copyDataBase();
                Log.e(TAG, "createDatabase database created");
            } catch (IOException mIOException) {
                throw new Error("ErrorCopyingDataBase");
            }
        }
    }

    // Check that the database file exists in databases folder
    private boolean checkDataBase() {
        return DB_FILE.exists();
    }

    // Copy the database from assets
    private void copyDataBase() throws IOException {
        InputStream mInput = mContext.getAssets().open(DB_NAME);
        OutputStream mOutput = new FileOutputStream(DB_FILE);
        byte[] mBuffer = new byte[1024];
        int mLength;
        while ((mLength = mInput.read(mBuffer)) > 0) {
            mOutput.write(mBuffer, 0, mLength);
        }
        mOutput.flush();
        mOutput.close();
        mInput.close();
    }

    // Open the database, so we can query it
    public boolean openDataBase() throws SQLException {
        // Log.v("DB_PATH", DB_FILE.getAbsolutePath());
        mDataBase = SQLiteDatabase.openDatabase(DB_FILE, null, SQLiteDatabase.CREATE_IF_NECESSARY);
        // mDataBase = SQLiteDatabase.openDatabase(DB_FILE, null, SQLiteDatabase.NO_LOCALIZED_COLLATORS);
        return mDataBase != null;
    }

    @Override
    public synchronized void close() {
        if(mDataBase != null) {
            mDataBase.close();
        }
        super.close();
    }

}

Write a DataAdapter class like:

import java.io.IOException;
import android.content.Context;
import android.database.Cursor;
import android.database.SQLException;
import android.database.sqlite.SQLiteDatabase;
import android.util.Log;

public class TestAdapter {

    protected static final String TAG = "DataAdapter";

    private final Context mContext;
    private SQLiteDatabase mDb;
    private DataBaseHelper mDbHelper;

    public TestAdapter(Context context) {
        this.mContext = context;
        mDbHelper = new DataBaseHelper(mContext);
    }

    public TestAdapter createDatabase() throws SQLException {
        try {
            mDbHelper.createDataBase();
        } catch (IOException mIOException) {
            Log.e(TAG, mIOException.toString() + "  UnableToCreateDatabase");
            throw new Error("UnableToCreateDatabase");
        }
        return this;
    }

    public TestAdapter open() throws SQLException {
        try {
            mDbHelper.openDataBase();
            mDbHelper.close();
            mDb = mDbHelper.getReadableDatabase();
        } catch (SQLException mSQLException) {
            Log.e(TAG, "open >>"+ mSQLException.toString());
            throw mSQLException;
        }
        return this;
    }

    public void close() {
        mDbHelper.close();
    }

     public Cursor getTestData() {
         try {
             String sql ="SELECT * FROM myTable";
             Cursor mCur = mDb.rawQuery(sql, null);
             if (mCur != null) {
                mCur.moveToNext();
             }
             return mCur;
         } catch (SQLException mSQLException) {
             Log.e(TAG, "getTestData >>"+ mSQLException.toString());
             throw mSQLException;
         }
     }
}

Now you can use it like:

TestAdapter mDbHelper = new TestAdapter(urContext);
mDbHelper.createDatabase();
mDbHelper.open();

Cursor testdata = mDbHelper.getTestData();

mDbHelper.close();

EDIT: Thanks to JDx

For Android 4.1 (Jelly Bean), change:

DB_PATH = "/data/data/" + context.getPackageName() + "/databases/";

to:

DB_PATH = context.getApplicationInfo().dataDir + "/databases/";

in the DataHelper class, this code will work on Jelly Bean 4.2 multi-users.

EDIT: Instead of using hardcoded path, we can use

DB_PATH = context.getDatabasePath(DB_NAME).getAbsolutePath();

which will give us the full path to the database file and works on all Android versions

If a table name contains underscores or upper case, you need to surround it in double-quotes.

SELECT * from "Table_Name";

This fixed the same issue for me: My eclipse is installed in /usr/local/bin/eclipse

1) Changed permission for eclipse from root to owner: sudo chown -R $USER eclipse

2) Right click on project/Maven right click on Update Maven select Force update maven project

This was the shortest way I could find to sort a DataTable without having to create any new variables.

DataTable.DefaultView.Sort = "ColumnName ASC"
DataTable = DataTable.DefaultView.ToTable

Where:

ASC - Ascending

DESC - Descending

ColumnName - The column you want to sort by

DataTable - The table you want to sort

I tried the code by @alex-martelli but found some discrepancies

python -mtimeit -s "xs=range(123456)" "map(hex, xs)"
1000000 loops, best of 5: 218 nsec per loop
python -mtimeit -s "xs=range(123456)" "[hex(x) for x in xs]"
10 loops, best of 5: 19.4 msec per loop

map takes the same amount of time even for very large ranges while using list comprehension takes a lot of time as is evident from my code. So apart from being considered "unpythonic", I have not faced any performance issues relating to usage of map.

No. This is not possible. Use something like supervisord to get an ssh server if that's needed. Although, I definitely question the need.

So I created an account just so I could help fix this problem that is plaguing a lot of people and where the fixes above aren't working.

If you get this error and nothing here helps. Try clicking the "Resume program play button" until the program finishes past the error. Then click in the console tab next to debug and read the red text.

I was getting that source code error even though my issue was trying to insert a value into a null Array. Step 1 Click the resume button

Step 2 Click the console tab and read the red text

Guidelines from MSDN: Using decimal, float, and real Data

The default maximum precision of numeric and decimal data types is 38. In Transact-SQL, numeric is functionally equivalent to the decimal data type. Use the decimal data type to store numbers with decimals when the data values must be stored exactly as specified.

The behavior of float and real follows the IEEE 754 specification on approximate numeric data types. Because of the approximate nature of the float and real data types, do not use these data types when exact numeric behavior is required, such as in financial applications, in operations involving rounding, or in equality checks. Instead, use the integer, decimal, money, or smallmoney data types. Avoid using float or real columns in WHERE clause search conditions, especially the = and <> operators. It is best to limit float and real columns to > or < comparisons.

I think your best shot is a border-left property that is assigned to each one of the lis except the first one (You would have to give the first one a class named first and explicitly remove the border for that).

Even if you are generating the <li> programmatically, assigning a first class should be easy.

I would suggest you take the easy path first, carefully isolating the IPC mechanism so that you can change from socket to pipe, but I would definitely go with socket first. You should be sure IPC performance is a problem before preemptively optimizing.

And if you get in trouble because of IPC speed, I think you should consider switching to shared memory rather than going to pipe.

If you want to do some transfer speed testing, you should try socat, which is a very versatile program that allows you to create almost any kind of tunnel.

Variable name: ANDROID_SDK_HOME
Variable value: C:\Users>User Name

worked for me.

It'll be easier (and more "proper", see below) if you just run your script as

myprogram /path/to/file

Then you can access the path within the script as $1 (for argument #1, similarly $2 is argument #2, etc.)

file="$1"
externalprogram "$file" [other parameters]

Or just

externalprogram "$1" [otherparameters]

If you want to extract the path from something like --file=/path/to/file, that's usually done with the getopts shell function. But that's more complicated than just referencing $1, and besides, switches like --file= are intended to be optional. I'm guessing your script requires a file name to be provided, so it doesn't make sense to pass it in an option.

Have you looked into rasdial?

Just incase anyone wanted to do this and finds this in the future, you can use rasdial.exe from command prompt to connect to a VPN network

ie rasdial "VPN NETWORK NAME" "Username" *

it will then prompt for a password, else you can use "username" "password", this is however less secure

_{http://www.msfn.org/board/topic/113128-connect-to-vpn-from-cmdexe-vista/?p=747265}

If you use Spring frameworks, then you can use CollectionUtils to check against both Collections (List, Array) and Map etc.

if(CollectionUtils.isEmpty(...)) {...}

In addition to the other answers, this error can result if there's an inconsistency in an order by clause. For instance:

select 
    substr(year_month, 1, 4)
    ,count(*) as tot
from
    schema.tbl
group by
    substr(year_month, 1, 4)
order by
    year_month

This happened to me today after my Macbook's battery died. I think this can be caused by improper shutdown. All you have to do in cases such as mine is delete postmaster.pid

Navigate to the folder

cd /usr/local/var/postgres

Check to see if postmaster.pid is present

ls

Remove postmaster.pid

rm postmaster.pid

You can use Ajax calls or $_GET["String"]; Method

I recommend: Twisted (http://twistedmatrix.com)

an event-driven networking engine written in Python and licensed under the open source MIT license.

It's cross-platform and was preinstalled on OS X 10.5 to 10.12. Amongst other things you can start up a simple web server in the current directory with:

twistd -no web --path=.

Details

Explanation of Options (see twistd --help for more):

-n, --nodaemon       don't daemonize, don't use default umask of 0077
-o, --no_save        do not save state on shutdown

"web" is a Command that runs a simple web server on top of the Twisted async engine. It also accepts command line options (after the "web" command - see twistd web --help for more):

  --path=             <path> is either a specific file or a directory to be
                      set as the root of the web server. Use this if you
                      have a directory full of HTML, cgi, php3, epy, or rpy
                      files or any other files that you want to be served up
                      raw.

There are also a bunch of other commands such as:

conch            A Conch SSH service.
dns              A domain name server.
ftp              An FTP server.
inetd            An inetd(8) replacement.
mail             An email service
... etc

Installation

Ubuntu

sudo apt-get install python-twisted-web (or python-twisted for the full engine)

Mac OS-X (comes preinstalled on 10.5 - 10.12, or is available in MacPorts and through Pip)

sudo port install py-twisted

Windows

installer available for download at http://twistedmatrix.com/

HTTPS

Twisted can also utilise security certificates to encrypt the connection. Use this with your existing --path and --port (for plain HTTP) options.

twistd -no web -c cert.pem -k privkey.pem --https=4433

Access is a great multi-user database. It has lots of built in features to handle the multi-user situation. In fact, it is so very popular because it is such a great multi-user database. There is an upper limit on how many users can all use the database at the same time doing updates and edits - depending on how knowledgeable the developer is about access and how the database has been designed - anywhere from 20 users to approx 50 users. Some access databases can be built to handle up to 50 concurrent users, while many others can handle 20 or 25 concurrent users updating the database. These figures have been observed for databases that have been in use for several or more years and have been discussed many times on the access newsgroups.

I think that if you stick strictly with TSQL that this is the fastest way to truncate the time:

 select convert(datetime,convert(int,convert(float,[Modified])))

I found this truncation method to be about 5% faster than the DateAdd method. And this can be easily modified to round to the nearest day like this:

select convert(datetime,ROUND(convert(float,[Modified]),0))

If you just want to check if the file uploaded is an image you can just try to load it into <img> tag an check for any error callback.

Example:

var input = document.getElementsByTagName('input')[0];
var reader = new FileReader();

reader.onload = function (e) {
    imageExists(e.target.result, function(exists){
        if (exists) {

            // Do something with the image file.. 

        } else {

            // different file format

        }
    });
};

reader.readAsDataURL(input.files[0]);


function imageExists(url, callback) {
    var img = new Image();
    img.onload = function() { callback(true); };
    img.onerror = function() { callback(false); };
    img.src = url;
}

You cannot use the Directory directive in .htaccess. However if you create a .htaccess file in the /system directory and place the following in it, you will get the same result

#place this in /system/.htaccess as you had before
deny from all

select column1, coulumn2, case when colum1=column2 then 'true' else 'false' end from table;

HTH

I am assuming you mean using XSD files. Surprisingly there aren't many python XML libraries that support this. lxml does however. Check Validation with lxml. The page also lists how to use lxml to validate with other schema types.

TLS (Transport Level Security) is the slightly broader term that has replaced SSL (Secure Sockets Layer) in securing HTTP communications. So what you are being asked to do is enable SSL.

Your code is fine, but the problem is inside the batch file.

You have to show the content of the bat file, your problem is in the paths inside the bat file.

Try to do...

 DELIMITER $$
        CREATE TRIGGER aumentarsalario 
        BEFORE INSERT 
        ON empregados
        FOR EACH ROW
        BEGIN
          if (NEW.SALARIO < 900) THEN 
             set NEW.SALARIO = NEW.SALARIO + (NEW.SALARIO * 0.1);
          END IF;
        END $$
  DELIMITER ;

You don't need 2 style attributes - just use one:

<img src="http://img705.imageshack.us/img705/119/original120x75.png" 
                                     style="height:100px;width:100px;" alt="25"/>

Consider, however, using a CSS class instead:

CSS:

.100pxSquare
{
  width: 100px;
  height: 100px;
}

HTML:

<img src="http://img705.imageshack.us/img705/119/original120x75.png" 
                                          class="100pxSquare" alt="25"/>

You were looking for help on installations with pip. You can find it with the following command:

pip install --help

Running pip install -e /path/to/package installs the package in a way, that you can edit the package, and when a new import call looks for it, it will import the edited package code. This can be very useful for package development.

An example, available for POSIX compliant systems :

/*
 * This program displays the names of all files in the current directory.
 */

#include <dirent.h> 
#include <stdio.h> 

int main(void) {
  DIR *d;
  struct dirent *dir;
  d = opendir(".");
  if (d) {
    while ((dir = readdir(d)) != NULL) {
      printf("%s\n", dir->d_name);
    }
    closedir(d);
  }
  return(0);
}

Beware that such an operation is platform dependant in C.

I'll be honest here. . .everything above may or may not be true, but it all seems WAY too complicated, or doesn't address knowing what tab is being used server side.

Sometimes we need to apply Occam's razor.

Here's the Occam's approach: (no, I'm not Occam, he died in 1347)

1) assign a browser unique id to your page on load. . . if and only if the window doesn't have an id yet (so use a prefix and a detection)

2) on every page you have (use a global file or something) simply put code in place to detect the focus event and/or mouseover event. (I'll use jquery for this part, for ease of code writing)

3) in your focus (and/or mouseover) function, set a cookie with the window.name in it

4) read that cookie value from your server side when you need to read/write tab specific data.

Client side:

//Events 
$(window).ready(function() {generateWindowID()});
$(window).focus(function() {setAppId()});
$(window).mouseover(function() {setAppId()});


function generateWindowID()
{
    //first see if the name is already set, if not, set it.
    if (se_appframe().name.indexOf("SEAppId") == -1){
            "window.name = 'SEAppId' + (new Date()).getTime()
    }
    setAppId()
}

function setAppId()
{
    //generate the cookie
    strCookie = 'seAppId=' + se_appframe().name + ';';
    strCookie += ' path=/';

    if (window.location.protocol.toLowerCase() == 'https:'){
        strCookie += ' secure;';
    }

    document.cookie = strCookie;
}

server side (C# - for example purposes)

//variable name 
string varname = "";
HttpCookie aCookie = Request.Cookies["seAppId"];
if(aCookie != null) {
     varname  = Request.Cookies["seAppId"].Value + "_";
}
varname += "_mySessionVariable";

//write session data 
Session[varname] = "ABC123";

//readsession data 
String myVariable = Session[varname];

Done.

Using jQuery ...

$('#submitButtonsId').click(
    function(){
        $(#myTextInput).val('');
    });

Using pure Javascript ...

var btn = document.getElementById('submitButton');
btn.onclick = function(){ document.getElementById('myTextInput').value="" };

Go to Start->All Programs-> Microsoft SQL Server 2012-> Configuration Tool -> Click SQL Server Configuration Manager.

If you see that SQL Server/ SQL Server Browser State is 'stopped'.Right click on SQL Server/SQL Server Browser and click start. In some cases above state can stop though TCP connection to port 1433 is assigned.

It simply wants the ASP control on your ASPX page. I usually place mine right under the tag, or inside first Content area in the master's body (if your using a master page)

<body>
    <form id="form1" runat="server">
        <asp:ScriptManager ID="scriptManager" runat="server"></asp:ScriptManager>
        <div>
            [Content]
        </div>
    </form>
</body>

Not directly, but you can extend the class to modify its get method. Here is a ready to use example: http://www.java2s.com/Code/Java/Collections-Data-Structure/ExtendedVersionofjavautilHashMapthatprovidesanextendedgetmethodaccpetingadefaultvalue.htm

Another option to avoid nesting two different environments (like multicols and enumerate).

The environment called tasks from the package with the same name seems to me very easy to customize thanks to a variety of options (pdf guide here).

This code:

\documentclass{article}
\usepackage{tasks}

%\settasks{style=itemize}

\begin{document}
Text text text text text text text text text text text text 
text text text text text text text text text text text text 
text text text text text text text text text text text text.

\begin{tasks}(2)
\task[*] a
\task[*] b
\task[*] c
\task[*] d
\task[*] e
\task[*] f
\end{tasks}    

Text text text text text text text text text text text text 
text text text text text text text text text text text text 
text text text text text text text text text text text text.
\end{document}

produces this output

The package tasks was updated in August 2020 and it was originally created specifically for horizontally columned lists (see the screenshot just above here), the motivations behind this are resumed in the guide. If such arrangement of the items/tasks is acceptable, then this may be a good choice since it keeps - IMHO - the code tidy and flexible.

for Angular 8 - a mixture of null checking and @ViewChild static: false hackery

for a paging control waiting for async data

@ViewChild(MatPaginator, { static: false }) set paginator(paginator: MatPaginator) {
  if(!paginator) return;

If you want to delete all duplicates, but one out of each set of duplicates, this is one solution:

DELETE posts
FROM posts
LEFT JOIN (
    SELECT id
    FROM posts
    GROUP BY id
    HAVING COUNT(id) = 1

    UNION

    SELECT id
    FROM posts
    GROUP BY id
    HAVING COUNT(id) != 1
) AS duplicate USING (id)
WHERE duplicate.id IS NULL;

An SMS Push is a message to tell the terminal to initiate the session. This happens because you can't initiate an IP session simply because you don't know the IP Adress of the mobile terminal. Mostly used to send a few lines of data to end recipient, to the effect of sending information, or reminding of events.

WAP Push is an SMS within the header of which is included a link to a WAP address. On receiving a WAP Push, the compatible mobile handset automatically gives the user the option to access the WAP content on his handset. The WAP Push directs the end-user to a WAP address where content is stored ready for viewing or downloading onto the handset. This wap address may be a page or a WAP site.

The user may “take action” by using a developer-defined soft-key to immediately activate an application to accomplish a specific task, such as downloading a picture, making a purchase, or responding to a marketing offer.

background: linear-gradient(to bottom, rgba(0, 0, 0, 1), rgba(0, 0, 0, 0));

This renders a gradient, starting from solid black at the top, to fully transparent at the bottom.

When I add @ComponentScan("com.firstday.spring.boot.services") or scanBasePackages{"com.firstday.spring.boot.services"} jsp is not loaded. So when I add the parent package of project in @SpringBootApplication class it's working fine in my case

@SpringBootApplication(scanBasePackages = {"com.firstday.spring.boot"})
public class FirstDayApplication {

Using a normal css selector:

$('.sys input[type=text], .sys select').each(function() {...})

If you don't like the repetition:

$('.sys').find('input[type=text],select').each(function() {...})

Or more concisely, pass in the context argument:

$('input[type=text],select', '.sys').each(function() {...})

Note: Internally jQuery will convert the above to find() equivalent

http://api.jquery.com/jQuery/

Internally, selector context is implemented with the .find() method, so $('span', this) is equivalent to $(this).find('span').

I personally find the first alternative to be the most readable :), your take though

There are three ways of defining things in Scala:

• def defines a method
• val defines a fixed value (which cannot be modified)
• var defines a variable (which can be modified)

Looking at your code:

def person = new Person("Kumar",12)

This defines a new method called person. You can call this method only without () because it is defined as parameterless method. For empty-paren method, you can call it with or without '()'. If you simply write:

person

then you are calling this method (and if you don't assign the return value, it will just be discarded). In this line of code:

person.age = 20

what happens is that you first call the person method, and on the return value (an instance of class Person) you are changing the age member variable.

And the last line:

println(person.age)

Here you are again calling the person method, which returns a new instance of class Person (with age set to 12). It's the same as this:

println(person().age)

It seems that MediaStore.Images.Media.getBitmap was deprecated in API 29. The recommended way is to use ImageDecoder.createSource which was added in API 28.

Here's how getting the bitmap would be done:

val bitmap = if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.P) {
    ImageDecoder.decodeBitmap(ImageDecoder.createSource(requireContext().contentResolver, imageUri))
} else {
    MediaStore.Images.Media.getBitmap(requireContext().contentResolver, imageUri)
}

I think you could just use the String#length method...

http://ruby-doc.org/core-1.9.3/String.html#method-i-length

Example:

text = 'The quick brown fox jumps over the lazy dog.'
puts text.length > 25 ? 'Too many characters' : 'Accepted'

In Java 8 you can use something like this.

String[] strs = IntStream.range(0, 15)  // 15 is the size
    .mapToObj(i -> Integer.toString(i))
    .toArray(String[]::new);

If you are developing for Windows, the com0com project might be, what you are looking for.

It provides pairs of virtual COM ports that are linked via a nullmodem connetion. You can then use your favorite terminal application or whatever you like to send data to one COM port and recieve from the other one.

EDIT:

As Thomas pointed out the project lacks of a signed driver, which is especially problematic on certain Windows version (e.g. Windows 7 x64).

There are a couple of unofficial com0com versions around that do contain a signed driver. One recent verion (3.0.0.0) can be downloaded e.g. from here.

The Bitmap class is an implementation of the Image class. The Image class is an abstract class;

The Bitmap class contains 12 constructors that construct the Bitmap object from different parameters. It can construct the Bitmap from another bitmap, and the string address of the image.

The problem I was having with the rewrite is that some .htaccess files for Codeigniter, etc come with

RewriteBase /

Which doesn't seem to work in MAMP...at least for me.

Another option is to use sprintf.

For example,

char buffer[50];
sprintf( buffer, "My String" );

Good luck.

Try this:

switch (val)
{
    case VAL:
    {
        int newVal = 42;
    }
    break;
}

A Record lets you create a new type from a Union. The values in the Union are used as attributes of the new type.

For example, say I have a Union like this:

type CatNames = "miffy" | "boris" | "mordred";

Now I want to create an object that contains information about all the cats, I can create a new type using the values in the CatName Union as keys.

type CatList = Record<CatNames, {age: number}>

If I want to satisfy this CatList, I must create an object like this:

const cats:CatList = {
  miffy: { age:99 },
  boris: { age:16 },
  mordred: { age:600 }
}

You get very strong type safety:

• If I forget a cat, I get an error.
• If I add a cat that's not allowed, I get an error.
• If I later change CatNames, I get an error. This is especially useful because CatNames is likely imported from another file, and likely used in many places.

Real-world React example.

I used this recently to create a Status component. The component would receive a status prop, and then render an icon. I've simplified the code quite a lot here for illustrative purposes

I had a union like this:

type Statuses = "failed" | "complete";

I used this to create an object like this:

const icons: Record<
  Statuses,
  { iconType: IconTypes; iconColor: IconColors }
> = {
  failed: {
    iconType: "warning",
    iconColor: "red"
  },
  complete: {
    iconType: "check",
    iconColor: "green"
  };

I could then render by destructuring an element from the object into props, like so:

const Status = ({status}) => <Icon {...icons[status]} />

If the Statuses union is later extended or changed, I know my Status component will fail to compile and I'll get an error that I can fix immediately. This allows me to add additional error states to the app.

Note that the actual app had dozens of error states that were referenced in multiple places, so this type safety was extremely useful.

states.split() will return

['Alaska',
 'Alabama',
 'Arkansas',
 'American',
 'Samoa',
 'Arizona',
 'California',
 'Colorado']

If you need one random from them, then you have to use the random module:

import random

states = "... ..."

random_state = random.choice(states.split())

This is typically done manually by choosing the appropriate bits from the vector and then appending 0s.

For example, to shift a vector 8 bits

variable tmp : std_logic_vector(15 downto 0)
...
tmp := x"00" & tmp(15 downto 8);

Hopefully this simple answer is useful to someone

    JSONArray ja = new JSONArray(json);
    JSONObject ob = ja.getJSONObject(0);
    String nh = ob.getString("status");

[ { "status" : "true" } ]

where 'json' is a String and status is the key from which i will get value

Edit:

I benchmarked my original solution against other solutions suggests here and found that it is very inefficient.

The benchmark itself is very interesting (link) It compares 3 solutions (higher is better):

• @fregante (formerly called @bfred.it) solution, which adds values one by one (14,955 op/sec)
• @jameslk's solution, which uses a self invoking generator (5,089 op/sec)
• my own, which uses reduce & spread (3,434 op/sec)

As you can see, @fregante's solution is definitely the winner.

Performance + Immutability

With that in mind, here's a slightly modified version which doesn't mutates the original set and excepts a variable number of iterables to combine as arguments:

function union(...iterables) {
  const set = new Set();

  for (const iterable of iterables) {
    for (const item of iterable) {
      set.add(item);
    }
  }

  return set;
}

Usage:

const a = new Set([1, 2, 3]);
const b = new Set([1, 3, 5]);
const c = new Set([4, 5, 6]);

union(a,b,c) // {1, 2, 3, 4, 5, 6}

Original Answer

I would like to suggest another approach, using reduce and the spread operator:

Implementation

function union (sets) {
  return sets.reduce((combined, list) => {
    return new Set([...combined, ...list]);
  }, new Set());
}

Usage:

const a = new Set([1, 2, 3]);
const b = new Set([1, 3, 5]);
const c = new Set([4, 5, 6]);

union([a, b, c]) // {1, 2, 3, 4, 5, 6}

Tip:

We can also make use of the rest operator to make the interface a bit nicer:

function union (...sets) {
  return sets.reduce((combined, list) => {
    return new Set([...combined, ...list]);
  }, new Set());
}

Now, instead of passing an array of sets, we can pass an arbitrary number of arguments of sets:

union(a, b, c) // {1, 2, 3, 4, 5, 6}

I just inherited an old VB.NET console application and needed to set up a Global Exception Handler. Since this question mentions VB.NET a few times and is tagged with VB.NET, but all the other answers here are in C#, I thought I would add the exact syntax for a VB.NET application as well.

Public Sub Main()
    REM Set up Global Unhandled Exception Handler.
    AddHandler System.AppDomain.CurrentDomain.UnhandledException, AddressOf MyUnhandledExceptionEvent

    REM Do other stuff
End Sub

Public Sub MyUnhandledExceptionEvent(ByVal sender As Object, ByVal e As UnhandledExceptionEventArgs)
    REM Log Exception here and do whatever else is needed
End Sub

I used the REM comment marker instead of the single quote here because Stack Overflow seemed to handle the syntax highlighting a bit better with REM.

These are positional arguments of the script.

Executing

./script.sh Hello World

Will make

$0 = ./script.sh
$1 = Hello
$2 = World

Note

If you execute ./script.sh, $0 will give output ./script.sh but if you execute it with bash script.sh it will give output script.sh.

I generally agree with solutions given above. Namely with:

1. Using underscore in for-loop (2 and more lines)
2. Defining a normal while counter (3 and more lines)
3. Declaring a custom class with __nonzero__ implementation (many more lines)

If one is to define an object as in #3 I would recommend implementing protocol for with keyword or apply contextlib.

Further I propose yet another solution. It is a 3 liner and is not of supreme elegance, but it uses itertools package and thus might be of an interest.

from itertools import (chain, repeat)

times = chain(repeat(True, 2), repeat(False))
while next(times):
    print 'do stuff!'

In these example 2 is the number of times to iterate the loop. chain is wrapping two repeat iterators, the first being limited but the second is infinite. Remember that these are true iterator objects, hence they do not require infinite memory. Obviously this is much slower then solution #1. Unless written as a part of a function it might require a clean up for times variable.

You can resolve the issue by forcing the collation used in a query to be a particular collation, e.g. SQL_Latin1_General_CP1_CI_AS or DATABASE_DEFAULT. For example:

SELECT MyColumn
FROM FirstTable a
INNER JOIN SecondTable b
ON a.MyID COLLATE SQL_Latin1_General_CP1_CI_AS = 
b.YourID COLLATE SQL_Latin1_General_CP1_CI_AS

In the above query, a.MyID and b.YourID would be columns with a text-based data type. Using COLLATE will force the query to ignore the default collation on the database and instead use the provided collation, in this case SQL_Latin1_General_CP1_CI_AS.

Basically what's going on here is that each database has its own collation which "provides sorting rules, case, and accent sensitivity properties for your data" (from http://technet.microsoft.com/en-us/library/ms143726.aspx) and applies to columns with textual data types, e.g. VARCHAR, CHAR, NVARCHAR, etc. When two databases have differing collations, you cannot compare text columns with an operator like equals (=) without addressing the conflict between the two disparate collations.

If you Pass date from PHP you can use any format using STR_TO_DATE() mysql function . Let conseder you are inserting date via html form

$Tdate = "'".$_POST["Tdate"]."'" ;    //   10/04/2016
$Tdate = "STR_TO_DATE(".$Tdate.", '%d/%m/%Y')"  ;  
mysql_query("INSERT INTO `table` (`dateposted`) VALUES ('$Tdate')");

The dateposted should be mysql date type . or mysql will adds 00:00:00
in some case You better insert date and time together into DB so you can do calculation with hours and seconds . () .

$Tdate=date('Y/m/d H:i:s') ; // this to get current date as text .
$Tdate = "STR_TO_DATE(".$Tdate.", '%d/%m/%Y %H:%i:%s')"  ;  

The other solutions with window.location didn't work for me since they didn't make it refresh at all, so what I did was that I used an empty form to pass new and empty postdata to the same page. This is a way to do that based on this answer:

function refreshAndClearPost() {
    var form = document.createElement("form");
    form.method = "POST";
    form.action = location.href;
    form.style.display = "none";

    document.body.appendChild(form);
    form.submit();    //since the form is empty, it will pass empty postdata
    document.body.removeChild(form);
}

Determine if a cell is within a range using VBA in Microsoft Excel:

From the linked site (maintaining credit to original submitter):

VBA macro tip contributed by Erlandsen Data Consulting offering Microsoft Excel Application development, template customization, support and training solutions

Function InRange(Range1 As Range, Range2 As Range) As Boolean
    ' returns True if Range1 is within Range2
    InRange = Not (Application.Intersect(Range1, Range2) Is Nothing)
End Function


Sub TestInRange()
    If InRange(ActiveCell, Range("A1:D100")) Then
        ' code to handle that the active cell is within the right range
        MsgBox "Active Cell In Range!"
    Else
        ' code to handle that the active cell is not within the right range
        MsgBox "Active Cell NOT In Range!"
    End If
End Sub

You can convert a string to a DATE using the TO_DATE function, then reformat the date as another string using TO_CHAR, i.e.:

SELECT TO_CHAR(
         TO_DATE('15/August/2009,4:30 PM'
                ,'DD/Month/YYYY,HH:MI AM')
       ,'DD-MM-YYYY')
FROM DUAL;

15-08-2009

For example, if your table name is MYTABLE and the varchar2 column is MYDATESTRING:

SELECT TO_CHAR(
         TO_DATE(MYDATESTRING
                ,'DD/Month/YYYY,HH:MI AM')
       ,'DD-MM-YYYY')
FROM MYTABLE;

If you just need a very simple call, you can use URL directly:

import java.net.URL;

    new URL("http://wheredatapp.com").openStream();

Other answers may have shorter code but this one should be the most efficient and is easy to understand.

/**
 * Get key of the max value
 *
 * @var array $array
 * @return mixed
*/
function array_key_max_value($array)
{
    $max = null;
    $result = null;
    foreach ($array as $key => $value) {
        if ($max === null || $value > $max) {
            $result = $key;
            $max = $value;
        }
    }

    return $result;
}

I feel you should be using the Consumer interface instead of Function<T, R>.

A Consumer is basically a functional interface designed to accept a value and return nothing (i.e void)

In your case, you can create a consumer elsewhere in your code like this:

Consumer<Integer> myFunction = x -> {
    System.out.println("processing value: " + x);    
    .... do some more things with "x" which returns nothing...
}

Then you can replace your myForEach code with below snippet:

public static void myForEach(List<Integer> list, Consumer<Integer> myFunction) 
{
  list.forEach(x->myFunction.accept(x));
}

You treat myFunction as a first-class object.

Path.Combine(AppDomain.CurrentDomain.BaseDirectory, @"JukeboxV2.0\JukeboxV2.0\Datos\ich will.mp3")

base directory + your filename

If you want multiple string replacement:

NSString *s = @"foo/bar:baz.foo";
NSCharacterSet *doNotWant = [NSCharacterSet characterSetWithCharactersInString:@"/:."];
s = [[s componentsSeparatedByCharactersInSet: doNotWant] componentsJoinedByString: @""];
NSLog(@"%@", s); // => foobarbazfoo

You could add easy key binding:

Preference > Key binding - user :

[
    { "keys": ["super+l"], "command": "reindent"},
]

Now select the line or file and hit: command + l

This functionality is not built-in to C# 5 or below.
Update: C# 6 now supports string interpolation, see newer answers.

The recommended way to do this would be with String.Format:

string name = "Scott";
string output = String.Format("Hello {0}", name);

However, I wrote a small open-source library called SmartFormat that extends String.Format so that it can use named placeholders (via reflection). So, you could do:

string name = "Scott";
string output = Smart.Format("Hello {name}", new{name}); // Results in "Hello Scott".

Hope you like it!

The whole code in the document will be:

graph = {'A': ['B', 'C'],
             'B': ['C', 'D'],
             'C': ['D'],
             'D': ['C'],
             'E': ['F'],
             'F': ['C']}
def find_path(graph, start, end, path=[]):
        path = path + [start]
        if start == end:
            return path
        if start not in graph:
            return None
        for node in graph[start]:
            if node not in path:
                newpath = find_path(graph, node, end, path)
                if newpath: return newpath
        return None

After writing it, save the document and press F 5

After that, the code you will run in the Python IDLE shell will be:

find_path(graph, 'A','D')

The answer you should receive in IDLE is

Its totally depends upon your choice, that how you are implementing.
a. Attached process , ex: input on form and print on console
b. Independent process, ex: start a timer, don't close even if console exit.

//or -------------
Form1 f = new Form1();
f.ShowDialog();

for b, Use thread, or task anything, How to open win form independently?

In Jenkins ver. 1.635, it is impossible to show a native environment variable like this:

$BUILD_NUMBER or ${BUILD_NUMBER}

In this case, you have to set it in an other variable.

set BUILDNO = $BUILD_NUMBER
$BUILDNO

The skinny is that a CPU loads data from memory addresses, stores data to memory addresses, and execute instructions sequentially out of memory addresses, with some conditional jumps in the sequence of instructions processed. Each of these three categories of instructions involves computing an address to a memory cell to be used in the machine instruction. Because machine instructions are of a variable length depending on the particular instruction involved, and because we string a variable length of them together as we build our machine code, there is a two step process involved in calculating and building any addresses.

First we laying out the allocation of memory as best we can before we can know what exactly goes in each cell. We figure out the bytes, or words, or whatever that form the instructions and literals and any data. We just start allocating memory and building the values that will create the program as we go, and note down anyplace we need to go back and fix an address. In that place we put a dummy to just pad the location so we can continue to calculate memory size. For example our first machine code might take one cell. The next machine code might take 3 cells, involving one machine code cell and two address cells. Now our address pointer is 4. We know what goes in the machine cell, which is the op code, but we have to wait to calculate what goes in the address cells till we know where that data will be located, i.e. what will be the machine address of that data.

If there were just one source file a compiler could theoretically produce fully executable machine code without a linker. In a two pass process it could calculate all of the actual addresses to all of the data cells referenced by any machine load or store instructions. And it could calculate all of the absolute addresses referenced by any absolute jump instructions. This is how simpler compilers, like the one in Forth work, with no linker.

A linker is something that allows blocks of code to be compiled separately. This can speed up the overall process of building code, and allows some flexibility with how the blocks are later used, in other words they can be relocated in memory, for example adding 1000 to every address to scoot the block up by 1000 address cells.

So what the compiler outputs is rough machine code that is not yet fully built, but is laid out so we know the size of everything, in other words so we can start to calculate where all of the absolute addresses will be located. the compiler also outputs a list of symbols which are name/address pairs. The symbols relate a memory offset in the machine code in the module with a name. The offset being the absolute distance to the memory location of the symbol in the module.

That's where we get to the linker. The linker first slaps all of these blocks of machine code together end to end and notes down where each one starts. Then it calculates the addresses to be fixed by adding together the relative offset within a module and the absolute position of the module in the bigger layout.

Obviously I've oversimplified this so you can try to grasp it, and I have deliberately not used the jargon of object files, symbol tables, etc. which to me is part of the confusion.

Unless you specifically act to ensure otherwise, most classes don't have helpful results for either:

>>> class Sic(object): pass
... 
>>> print str(Sic())
<__main__.Sic object at 0x8b7d0>
>>> print repr(Sic())
<__main__.Sic object at 0x8b7d0>

As you see -- no difference, and no info beyond the class and object's id. If you only override one of the two...:

>>> class Sic(object): 
...   def __repr__(object): return 'foo'
... 
>>> print str(Sic())
foo
>>> print repr(Sic())
foo
>>> class Sic(object):
...   def __str__(object): return 'foo'
... 
>>> print str(Sic())
foo
>>> print repr(Sic())
<__main__.Sic object at 0x2617f0>
>>> 

as you see, if you override __repr__, that's ALSO used for __str__, but not vice versa.

Other crucial tidbits to know: __str__ on a built-on container uses the __repr__, NOT the __str__, for the items it contains. And, despite the words on the subject found in typical docs, hardly anybody bothers making the __repr__ of objects be a string that eval may use to build an equal object (it's just too hard, AND not knowing how the relevant module was actually imported makes it actually flat out impossible).

So, my advice: focus on making __str__ reasonably human-readable, and __repr__ as unambiguous as you possibly can, even if that interferes with the fuzzy unattainable goal of making __repr__'s returned value acceptable as input to __eval__!
