All the answers above, for some reason or another, did not work for me on SQL Server 2012. My situation was I accidently deleted all rows instead of just one row. After our DBA restored the table to dbo.foo_bak, I used the below to restore. NOTE: This only works if the backup table (represented by dbo.foo_bak) and the table that you are writing to (dbo.foo) have the exact same column names.

This is what worked for me using a hybrid of a bunch of different answers:

USE [database_name];
GO
SET IDENTITY_INSERT dbo.foo ON;
GO
INSERT INTO [dbo].[foo]
           ([rown0]
           ,[row1]
           ,[row2]
           ,[row3]
           ,...
           ,[rown])
     SELECT * FROM [dbo].[foo_bak];
GO
SET IDENTITY_INSERT dbo.foo OFF;
GO

This version of my answer is helpful if you have primary and foreign keys.

Monkey patch in namespace php >= 5.3

A less evasive method than modifying the interpreter is the monkey patch.

Monkey patching is the art of replacing the actual implementation with a similar "patch" of your own.

Ninja skills

Before you can monkey patch like a PHP Ninja we first have to understand PHPs namespaces.

Since PHP 5.3 we got introduced to namespaces which you might at first glance denote to be equivalent to something like java packages perhaps, but it's not quite the same. Namespaces, in PHP, is a way to encapsulate scope by creating a hierarchy of focus, especially for functions and constants. As this topic, fallback to global functions, aims to explain.

If you don't provide a namespace when calling a function, PHP first looks in the current namespace then moves down the hierarchy until it finds the first function declared within that prefixed namespace and executes that. For our example if you are calling print_r(); from namespace My\Awesome\Namespace; What PHP does is to first look for a function called My\Awesome\Namespace\print_r(); then My\Awesome\print_r(); then My\print_r(); until it finds the PHP built in function in the global namespace \print_r();.

You will not be able to define a function print_r($object) {} in the global namespace because this will cause a name collision since a function with that name already exists.

Expect a fatal error to the likes of:

Fatal error: Cannot redeclare print_r()

But nothing stops you, however, from doing just that within the scope of a namespace.

Patching the monkey

Say you have a script using several print_r(); calls.

Example:

<?php
     print_r($some_object);
     // do some stuff
     print_r($another_object);
     // do some other stuff
     print_r($data_object);
     // do more stuff
     print_r($debug_object);

But you later change your mind and you want the output wrapped in <pre></pre> tags instead. Ever happened to you?

Before you go and change every call to print_r(); consider monkey patching instead.

Example:

<?php
    namespace MyNamespace {
        function print_r($object) 
        {
            echo "<pre>", \print_r($object, true), "</pre>"; 
        }

        print_r($some_object);
        // do some stuff
        print_r($another_object);
        // do some other stuff
        print_r($data_object);
        // do more stuff
        print_r($debug_object);
    }

Your script will now be using MyNamespace\print_r(); instead of the global \print_r();

Works great for mocking unit tests.

If you dont want to change the format of date and time from the timestamp, you can use the explode function in php

$timestamp = "2012-04-02 02:57:54"
$datetime = explode(" ",$timestamp);
$date = $datetime[0];
$time = $datetime[1];

Here is how I would do it if working with a large number of "to remove" values that would take a long time to manually remove.

• -Put Original List in Column A -Put To Remove list in Column B -Select both columns, then "Conditional Formatting"
  -Select "Hightlight Cells Rules" --> "Duplicate Values"
  -The duplicates should be hightlighted in both columns
  -Then select Column A and then "Sort & Filter" ---> "Custom Sort"
  -In the dialog box that appears, select the middle option "Sort On" and pick "Cell Color"
  -Then select the next option "Sort Order" and choose "No Cell Color" "On bottom"
  -All the highlighted cells should be at the top of the list. -Select all the highlighted cells by scrolling down the list, then click delete.

• Binary search tree: when inorder traversal is made on binary tree, you get sorted values of inserted items
• Binary tree: no sorted order is found in any kind of traversal

You can use Date.getTime() function, or the Date object itself which when divided returns the time in milliseconds.

var d = new Date();

d/1000
> 1510329641.84

d.getTime()/1000
> 1510329641.84

Another way (although it is a longer code) but it is faster than the above codes. Check it using %timeit function:

df[df.index.isin([1,3])]

PS: You figure out the reason

It might be considered a bit 'hacky' but depending the size and contents of the slice, you can join the slice together and do a string search.

For example you have a slice containing single word values (e.g. "yes", "no", "maybe"). These results are appended to a slice. If you want to check if this slice contains any "maybe" results, you may use

exSlice := ["yes", "no", "yes", "maybe"]
if strings.Contains(strings.Join(exSlice, ","), "maybe") {
  fmt.Println("We have a maybe!")
}

How suitable this is really depends on the size of the slice and length of its members. There may be performance or suitability issues for large slices or long values, but for smaller slices of finite size and simple values it is a valid one-liner to achieve the desired result.

Bitcode (iOS, watchOS)

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

Basically this concept is somewhat similar to java where byte code is run on different JVM's and in this case the bitcode is placed on iTune store and instead of giving the intermediate code to different platforms(devices) it provides the compiled code which don't need any virtual machine to run.

Thus we need to create the bitcode once and it will be available for existing or coming devices. It's the Apple's headache to compile an make it compatible with each platform they have.

Devs don't have to make changes and submit the app again to support new platforms.

Let's take the example of iPhone 5s when apple introduced x64 chip in it. Although x86 apps were totally compatible with x64 architecture but to fully utilise the x64 platform the developer has to change the architecture or some code. Once s/he's done the app is submitted to the app store for the review.

If this bitcode concept was launched earlier then we the developers doesn't have to make any changes to support the x64 bit architecture.

Here's another way to possibly answer your question using the find function which gives you a literal numerical value of where something truly is

open('file', 'r').read().find('')

in find write the word you want to find and 'file' stands for your file name

Had the same problem with malformed error Deleted the line apply plugin: 'com.google.gms.google-services' And the build got successful

You can use mixin and change var in something like this.

// This is a global mixin, it is applied to every vue instance_x000D_
Vue.mixin({_x000D_
  data: function() {_x000D_
    return {_x000D_
      globalVar:'global'_x000D_
    }_x000D_
  }_x000D_
})_x000D_
_x000D_
Vue.component('child', {_x000D_
  template: "<div>In Child: {{globalVar}}</div>"_x000D_
});_x000D_
_x000D_
new Vue({_x000D_
  el: '#app',_x000D_
  created: function() {_x000D_
    this.globalVar = "It's will change global var";_x000D_
  }_x000D_
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.1.3/vue.js"></script>_x000D_

See perldoc perlop. Use lt, gt, eq, ne, and cmp as appropriate for string comparisons:

Binary eq returns true if the left argument is stringwise equal to the right argument.

Binary ne returns true if the left argument is stringwise not equal to the right argument.

Binary cmp returns -1, 0, or 1 depending on whether the left argument is stringwise less than, equal to, or greater than the right argument.

Binary ~~ does a smartmatch between its arguments. ...

lt, le, ge, gt and cmp use the collation (sort) order specified by the current locale if a legacy use locale (but not use locale ':not_characters') is in effect. See perllocale. Do not mix these with Unicode, only with legacy binary encodings. The standard Unicode::Collate and Unicode::Collate::Locale modules offer much more powerful solutions to collation issues.

window.addEventListener("scroll",function(){
    window.lastScrollTime = new Date().getTime()
});
function is_scrolling() {
    return window.lastScrollTime && new Date().getTime() < window.lastScrollTime + 500
}

Change the 500 to the number of milliseconds after the last scroll event at which you consider the user to be "no longer scrolling".

(addEventListener is better than onScroll because the former can coexist nicely with any other code that uses onScroll.)

I have come up with another solution with SingleTon class. Please tell me if any memory leakage is here.

import time,threading

class Singleton:
  __instance = None
  sleepTime = 1
  executeThread = False

  def __init__(self):
     if Singleton.__instance != None:
        raise Exception("This class is a singleton!")
     else:
        Singleton.__instance = self

  @staticmethod
  def getInstance():
     if Singleton.__instance == None:
        Singleton()
     return Singleton.__instance


  def startThread(self):
     self.executeThread = True
     self.threadNew = threading.Thread(target=self.foo_target)
     self.threadNew.start()
     print('doing other things...')


  def stopThread(self):
     print("Killing Thread ")
     self.executeThread = False
     self.threadNew.join()
     print(self.threadNew)


  def foo(self):
     print("Hello in " + str(self.sleepTime) + " seconds")


  def foo_target(self):
     while self.executeThread:
        self.foo()
        print(self.threadNew)
        time.sleep(self.sleepTime)

        if not self.executeThread:
           break


sClass = Singleton()
sClass.startThread()
time.sleep(5)
sClass.getInstance().stopThread()

sClass.getInstance().sleepTime = 2
sClass.startThread()

I have never done so, but it seems like

MATCH (head, head, body) AGAINST ('some words' IN BOOLEAN MODE)

Should give a double weight to matches found in the head.

Just read this comment on the docs page, Thought it might be of value to you:

Posted by Patrick O'Lone on December 9 2002 6:51am

It should be noted in the documentation that IN BOOLEAN MODE will almost always return a relevance of 1.0. In order to get a relevance that is meaningful, you'll need to:

SELECT MATCH('Content') AGAINST ('keyword1 keyword2') as Relevance 
FROM table 
WHERE MATCH ('Content') AGAINST('+keyword1+keyword2' IN BOOLEAN MODE) 
HAVING Relevance > 0.2 
ORDER BY Relevance DESC 

Notice that you are doing a regular relevance query to obtain relevance factors combined with a WHERE clause that uses BOOLEAN MODE. The BOOLEAN MODE gives you the subset that fulfills the requirements of the BOOLEAN search, the relevance query fulfills the relevance factor, and the HAVING clause (in this case) ensures that the document is relevant to the search (i.e. documents that score less than 0.2 are considered irrelevant). This also allows you to order by relevance.

This may or may not be a bug in the way that IN BOOLEAN MODE operates, although the comments I've read on the mailing list suggest that IN BOOLEAN MODE's relevance ranking is not very complicated, thus lending itself poorly for actually providing relevant documents. BTW - I didn't notice a performance loss for doing this, since it appears MySQL only performs the FULLTEXT search once, even though the two MATCH clauses are different. Use EXPLAIN to prove this.

So it would seem you may not need to worry about calling the fulltext search twice, though you still should "use EXPLAIN to prove this"

Use this syntax for VB.NET 2005/2008 compatibility:

Dim theVar As New List(Of String)(New String() {"one", "two", "three"})

Although the VB.NET 2010 syntax is prettier.

You can also retrieve it from the environment variables, but that is probably not secure, so I would go with Andrew's answer.

printenv USER

If you need to retrieve it from an app, like Node, it's easier to get it from the environment variables, such as

process.env.USER.

Another powershell method (I only wanted failures)

$ping = new-object System.Net.NetworkInformation.Ping
$target="192.168.0.1"
Write-Host "$(Get-Date -format 's') Start ping to $target"
while($true){
    $reply = $ping.send($target)
    if ($reply.status -eq "Success"){
        # ignore success    
        Start-Sleep -Seconds 1
    }
    else{
        Write-Host "$(Get-Date -format 's') Destination unreachable" $target

    }
}

The <a> tag doesn't have a disabled attribute, that's just for <input>s (and <select>s and <textarea>s).

To "disable" a link, you can remove its href attribute, or add a click handler that returns false.

Since ruby 2.4.0 you can use native Hash#transform_values method:

hash = {"a" => "b", "c" => "d"}
new_hash = hash.transform_values(&:upcase)
# => {"a" => "B", "c" => "D"}

There is also destructive Hash#transform_values! version.

You should probably do some validations before you actually execute your function :

function trim(str) {
    if(typeof str !== 'string') {
        throw new Error('only string parameter supported!');
    }

    return str.replace(/^\s+|\s+$/g,'');
}

I would like to propose a significantly faster (and memory efficient) alternative: strtok rather than preg_split.

$separator = "\r\n";
$line = strtok($subject, $separator);

while ($line !== false) {
    # do something with $line
    $line = strtok( $separator );
}

Testing the performance, I iterated 100 times over a test file with 17 thousand lines: preg_split took 27.7 seconds, whereas strtok took 1.4 seconds.

Note that though the $separator is defined as "\r\n", strtok will separate on either character - and as of PHP4.1.0, skip empty lines/tokens.

See the strtok manual entry: http://php.net/strtok

You can add a column to your data using various techniques. The quotes below come from the "Details" section of the relevant help text, [[.data.frame.

Data frames can be indexed in several modes. When [ and [[ are used with a single vector index (x[i] or x[[i]]), they index the data frame as if it were a list.

my.dataframe["new.col"] <- a.vector
my.dataframe[["new.col"]] <- a.vector

The data.frame method for $, treats x as a list

my.dataframe$new.col <- a.vector

When [ and [[ are used with two indices (x[i, j] and x[[i, j]]) they act like indexing a matrix

my.dataframe[ , "new.col"] <- a.vector

Since the method for data.frame assumes that if you don't specify if you're working with columns or rows, it will assume you mean columns.

For your example, this should work:

# make some fake data
your.df <- data.frame(no = c(1:4, 1:7, 1:5), h_freq = runif(16), h_freqsq = runif(16))

# find where one appears and 
from <- which(your.df$no == 1)
to <- c((from-1)[-1], nrow(your.df)) # up to which point the sequence runs

# generate a sequence (len) and based on its length, repeat a consecutive number len times
get.seq <- mapply(from, to, 1:length(from), FUN = function(x, y, z) {
            len <- length(seq(from = x[1], to = y[1]))
            return(rep(z, times = len))
         })

# when we unlist, we get a vector
your.df$group <- unlist(get.seq)
# and append it to your original data.frame. since this is
# designating a group, it makes sense to make it a factor
your.df$group <- as.factor(your.df$group)

RUN /bin/sh -c "apk add --no-cache bash"

worked for me.

Something like this if you're into regex, not sure of the exact syntax for the replace tho!

MyNumberAsString.replace(/(\d)(?=(\d\d\d)+(?!\d))/g, "$1,");

If you just want an array of month names from the beginning of the year to the end e.g. to populate a drop-down select, I would just use the following;

for ($i = 0; $i < 12; ++$i) {
  $months[$m] = $m = date("F", strtotime("January +$i months"));
}

Had this issue again just now, and believe it or not, all I had to do was close the developer tools. Apparently the Console tab has the focus priority over the page content.

With Windows 2012 R2 (Win 8.1) and up, you also have the "official" Import-PfxCertificate cmdlet

Here are some essential parts of code (an adaptable example):

Invoke-Command -ComputerName $Computer -ScriptBlock {
        param(
            [string] $CertFileName,
            [string] $CertRootStore,
            [string] $CertStore,
            [string] $X509Flags,
            $PfxPass)
        $CertPath = "$Env:SystemRoot\$CertFileName"
        $Pfx = New-Object System.Security.Cryptography.X509Certificates.X509Certificate2
        # Flags to send in are documented here: https://msdn.microsoft.com/en-us/library/system.security.cryptography.x509certificates.x509keystorageflags%28v=vs.110%29.aspx
        $Pfx.Import($CertPath, $PfxPass, $X509Flags) #"Exportable,PersistKeySet")
        $Store = New-Object -TypeName System.Security.Cryptography.X509Certificates.X509Store -ArgumentList $CertStore, $CertRootStore
        $Store.Open("MaxAllowed")
        $Store.Add($Pfx)
        if ($?)
        {
            "${Env:ComputerName}: Successfully added certificate."
        }
        else
        {
            "${Env:ComputerName}: Failed to add certificate! $($Error[0].ToString() -replace '[\r\n]+', ' ')"
        }
        $Store.Close()
        Remove-Item -LiteralPath $CertPath
    } -ArgumentList $TempCertFileName, $CertRootStore, $CertStore, $X509Flags, $Password

Based on mao47's code and some research, I wrote up a little article and a simple cmdlet for importing/pushing PFX certificates to remote computers.

Here's my article with more details and complete code that also works with PSv2 (default on Server 2008 R2 / Windows 7), so long as you have SMB enabled and administrative share access.

Remember to not capitalize your text when writing this command. For example:

Do write:

rails g model product title:string description:text image_url:string price:decimal

Do not write:

rails g Model product title:string description:text image_url:string price:decimal

At least it was a problem to me.

I would like to explain the Big-O in a little bit different aspect.

Big-O is just to compare the complexity of the programs which means how fast are they growing when the inputs are increasing and not the exact time which is spend to do the action.

IMHO in the big-O formulas you better not to use more complex equations (you might just stick to the ones in the following graph.) However you still might use other more precise formula (like 3^n, n^3, ...) but more than that can be sometimes misleading! So better to keep it as simple as possible.

I would like to emphasize once again that here we don't want to get an exact formula for our algorithm. We only want to show how it grows when the inputs are growing and compare with the other algorithms in that sense. Otherwise you would better use different methods like bench-marking.

The following should work:

$now = date('Y-m-d');
$reservations = Reservation::where('reservation_from', '>=', $now)
                           ->where('reservation_from', '<=', $to)
                           ->get();

C# equivalent of your code is

  class Imagedata : PDFStreamEngine
  {
     // C# uses "base" keyword whenever Java uses "super" 
     // so instead of super(...) in Java we should call its C# equivalent (base):
     public Imagedata()
       : base(ResourceLoader.loadProperties("org/apache/pdfbox/resources/PDFTextStripper.properties", true)) 
     { }

     // Java methods are virtual by default, when C# methods aren't.
     // So we should be sure that processOperator method in base class 
     // (that is PDFStreamEngine)
     // declared as "virtual"
     protected override void processOperator(PDFOperator operations, List arguments)
     {
        base.processOperator(operations, arguments);
     }
  }

Yes sure, provided you have its context. (See how to get canvas context here.)

var imgData = context.getImageData(0,0,canvas.width,canvas.height);
// { data: [r,g,b,a,r,g,b,a,r,g,..], ... }

function getPixel(imgData, index) {
  var i = index*4, d = imgData.data;
  return [d[i],d[i+1],d[i+2],d[i+3]] // Returns array [R,G,B,A]
}

// AND/OR

function getPixelXY(imgData, x, y) {
  return getPixel(imgData, y*imgData.width+x);
}

PS: If you plan to mutate the data and draw them back on the canvas, you can use subarray

var
  idt = imgData, // See previous code snippet
  a = getPixel(idt, 188411), // Array(4) [0, 251, 0, 255]
  b = idt.data.subarray(188411*4, 188411*4 + 4) // Uint8ClampedArray(4) [0, 251, 0, 255]

a[0] = 255 // Does nothing
getPixel(idt, 188411), // Array(4) [0, 251, 0, 255]

b[0] = 255 // Mutates the original imgData.data
getPixel(idt, 188411), // Array(4) [255, 251, 0, 255]

// Or use it in the function
function getPixel(imgData, index) {
  var i = index*4, d = imgData.data;
  return imgData.data.subarray(index, index+4) // Returns subarray [R,G,B,A]
}

You can experiment with this on http://qry.me/xyscope/, the code for this is in the source, just copy/paste it in the console.

Try this in Swift 3

array.remove(at: Index)

Instead of

array.removeAtIndex(index)

Update

"Declaration is only valid at file scope".

Make sure the object is in scope. You can give scope "internal", which is default.

index(of:<Object>) to work, class should conform to Equatable

Your script could be stopping, not because of the PHP timeout but because of the timeout in the browser you're using to access the script (ie. Firefox, Chrome, etc). Unfortunately there's seldom an easy way to extend this timeout, and in most browsers you simply can't. An option you have here is to access the script over a terminal. For example, on Windows you would make sure the PHP executable is in your path variable and then I think you execute:

C:\path\to\script> php script.php

Or, if you're using the PHP CGI, I think it's:

C:\path\to\script> php-cgi script.php

Plus, you would also set ini_set('max_execution_time', 0); in your script as others have mentioned. When running a PHP script this way, I'm pretty sure you can use buffer flushing to echo out the script's progress to the terminal periodically if you wish. The biggest issue I think with this method is there's really no way of stopping the script once it's started, other than stopping the entire PHP process or service.

I actually had an easy workaround on this one in which I nearly scratch my head on how to make it work. hahah!

Well, first I downloaded Bootstrap (the compiled css and js version).

Then I pasted all the bootstrap css files to the app/assets/stylesheets/.

And then I pasted all the bootstrap js files to the app/assets/javascripts/.

I reloaded the page and wallah! I just added bootstrap in my RoR!

You could set the @Input on the setter directly, as described below:

_allowDay: boolean;
get allowDay(): boolean {
    return this._allowDay;
}
@Input() set allowDay(value: boolean) {
    this._allowDay = value;
    this.updatePeriodTypes();

Step by step to setup zxing 3.2.1 in eclipse

1. Download zxing-master.zip from "https://github.com/zxing/zxing"
2. Unzip zxing-master.zip, Use eclipse to import "android" project in zxing-master
3. Download core-3.2.1.jar from "http://repo1.maven.org/maven2/com/google/zxing/core/3.2.1/"
4. Create "libs" folder in "android" project and paste cor-3.2.1.jar into the libs folder
5. Click on project: choose "properties" -> "Java Compiler" to change level to 1.7. Then click on "Android" change "Project build target" to android 4.4.2+, because using 1.7 requires compiling with Android 4.4
6. If "CameraConfigurationUtils.java" don't exist in "zxing-master/android/app/src/main/java/com/google/zxing/client/android/camera/". You can copy it from "zxing-master/android-core/src/main/java/com/google/zxing/client/android/camera/" and paste to your project.
7. Clean and build project. If your project show error about "switch - case", you should change them to "if - else".
8. Completed. Clean and build project.

This answer simply extends @Andy Hayden's, making it resilient to when numeric fields are nan, and wrapping it up into a function.

import pandas as pd
import numpy as np


def diff_pd(df1, df2):
    """Identify differences between two pandas DataFrames"""
    assert (df1.columns == df2.columns).all(), \
        "DataFrame column names are different"
    if any(df1.dtypes != df2.dtypes):
        "Data Types are different, trying to convert"
        df2 = df2.astype(df1.dtypes)
    if df1.equals(df2):
        return None
    else:
        # need to account for np.nan != np.nan returning True
        diff_mask = (df1 != df2) & ~(df1.isnull() & df2.isnull())
        ne_stacked = diff_mask.stack()
        changed = ne_stacked[ne_stacked]
        changed.index.names = ['id', 'col']
        difference_locations = np.where(diff_mask)
        changed_from = df1.values[difference_locations]
        changed_to = df2.values[difference_locations]
        return pd.DataFrame({'from': changed_from, 'to': changed_to},
                            index=changed.index)

So with your data (slightly edited to have a NaN in the score column):

import sys
if sys.version_info[0] < 3:
    from StringIO import StringIO
else:
    from io import StringIO

DF1 = StringIO("""id   Name   score                    isEnrolled           Comment

113  Zoe    NaN                     True                  " "
""")
DF2 = StringIO("""id   Name   score                    isEnrolled           Comment

112  Nick   1.21                     False                "Graduated"
113  Zoe    NaN                     False                "On vacation" """)
df1 = pd.read_table(DF1, sep='\s+', index_col='id')
df2 = pd.read_table(DF2, sep='\s+', index_col='id')
diff_pd(df1, df2)

Output:

If you want to exclude all the standard properties of the window object and view application-specific globals, this will print them to the Chrome console:

{

    const standardGlobals = new Set(["window", "self", "document", "name", "location", "customElements", "history", "locationbar", "menubar", "personalbar", "scrollbars", "statusbar", "toolbar", "status", "closed", "frames", "length", "top", "opener", "parent", "frameElement", "navigator", "origin", "external", "screen", "innerWidth", "innerHeight", "scrollX", "pageXOffset", "scrollY", "pageYOffset", "visualViewport", "screenX", "screenY", "outerWidth", "outerHeight", "devicePixelRatio", "clientInformation", "screenLeft", "screenTop", "defaultStatus", "defaultstatus", "styleMedia", "onsearch", "isSecureContext", "performance", "onappinstalled", "onbeforeinstallprompt", "crypto", "indexedDB", "webkitStorageInfo", "sessionStorage", "localStorage", "onabort", "onblur", "oncancel", "oncanplay", "oncanplaythrough", "onchange", "onclick", "onclose", "oncontextmenu", "oncuechange", "ondblclick", "ondrag", "ondragend", "ondragenter", "ondragleave", "ondragover", "ondragstart", "ondrop", "ondurationchange", "onemptied", "onended", "onerror", "onfocus", "onformdata", "oninput", "oninvalid", "onkeydown", "onkeypress", "onkeyup", "onload", "onloadeddata", "onloadedmetadata", "onloadstart", "onmousedown", "onmouseenter", "onmouseleave", "onmousemove", "onmouseout", "onmouseover", "onmouseup", "onmousewheel", "onpause", "onplay", "onplaying", "onprogress", "onratechange", "onreset", "onresize", "onscroll", "onseeked", "onseeking", "onselect", "onstalled", "onsubmit", "onsuspend", "ontimeupdate", "ontoggle", "onvolumechange", "onwaiting", "onwebkitanimationend", "onwebkitanimationiteration", "onwebkitanimationstart", "onwebkittransitionend", "onwheel", "onauxclick", "ongotpointercapture", "onlostpointercapture", "onpointerdown", "onpointermove", "onpointerup", "onpointercancel", "onpointerover", "onpointerout", "onpointerenter", "onpointerleave", "onselectstart", "onselectionchange", "onanimationend", "onanimationiteration", "onanimationstart", "ontransitionrun", "ontransitionstart", "ontransitionend", "ontransitioncancel", "onafterprint", "onbeforeprint", "onbeforeunload", "onhashchange", "onlanguagechange", "onmessage", "onmessageerror", "onoffline", "ononline", "onpagehide", "onpageshow", "onpopstate", "onrejectionhandled", "onstorage", "onunhandledrejection", "onunload", "alert", "atob", "blur", "btoa", "cancelAnimationFrame", "cancelIdleCallback", "captureEvents", "clearInterval", "clearTimeout", "close", "confirm", "createImageBitmap", "fetch", "find", "focus", "getComputedStyle", "getSelection", "matchMedia", "moveBy", "moveTo", "open", "postMessage", "print", "prompt", "queueMicrotask", "releaseEvents", "requestAnimationFrame", "requestIdleCallback", "resizeBy", "resizeTo", "scroll", "scrollBy", "scrollTo", "setInterval", "setTimeout", "stop", "webkitCancelAnimationFrame", "webkitRequestAnimationFrame", "chrome", "caches", "ondevicemotion", "ondeviceorientation", "ondeviceorientationabsolute", "originAgentCluster", "cookieStore", "showDirectoryPicker", "showOpenFilePicker", "showSaveFilePicker", "speechSynthesis", "onpointerrawupdate", "trustedTypes", "crossOriginIsolated", "openDatabase", "webkitRequestFileSystem", "webkitResolveLocalFileSystemURL"]);

    for (const key of Object.keys(window)) {
        if (!standardGlobals.has(key)) {
            console.log(key)
        }
    }
}

The script works well as a bookmarklet. To use the script as a bookmarklet, create a new bookmark and replace the URL with the following:

javascript:(() => {
    const standardGlobals = new Set(["window", "self", "document", "name", "location", "customElements", "history", "locationbar", "menubar", "personalbar", "scrollbars", "statusbar", "toolbar", "status", "closed", "frames", "length", "top", "opener", "parent", "frameElement", "navigator", "origin", "external", "screen", "innerWidth", "innerHeight", "scrollX", "pageXOffset", "scrollY", "pageYOffset", "visualViewport", "screenX", "screenY", "outerWidth", "outerHeight", "devicePixelRatio", "clientInformation", "screenLeft", "screenTop", "defaultStatus", "defaultstatus", "styleMedia", "onsearch", "isSecureContext", "performance", "onappinstalled", "onbeforeinstallprompt", "crypto", "indexedDB", "webkitStorageInfo", "sessionStorage", "localStorage", "onabort", "onblur", "oncancel", "oncanplay", "oncanplaythrough", "onchange", "onclick", "onclose", "oncontextmenu", "oncuechange", "ondblclick", "ondrag", "ondragend", "ondragenter", "ondragleave", "ondragover", "ondragstart", "ondrop", "ondurationchange", "onemptied", "onended", "onerror", "onfocus", "onformdata", "oninput", "oninvalid", "onkeydown", "onkeypress", "onkeyup", "onload", "onloadeddata", "onloadedmetadata", "onloadstart", "onmousedown", "onmouseenter", "onmouseleave", "onmousemove", "onmouseout", "onmouseover", "onmouseup", "onmousewheel", "onpause", "onplay", "onplaying", "onprogress", "onratechange", "onreset", "onresize", "onscroll", "onseeked", "onseeking", "onselect", "onstalled", "onsubmit", "onsuspend", "ontimeupdate", "ontoggle", "onvolumechange", "onwaiting", "onwebkitanimationend", "onwebkitanimationiteration", "onwebkitanimationstart", "onwebkittransitionend", "onwheel", "onauxclick", "ongotpointercapture", "onlostpointercapture", "onpointerdown", "onpointermove", "onpointerup", "onpointercancel", "onpointerover", "onpointerout", "onpointerenter", "onpointerleave", "onselectstart", "onselectionchange", "onanimationend", "onanimationiteration", "onanimationstart", "ontransitionrun", "ontransitionstart", "ontransitionend", "ontransitioncancel", "onafterprint", "onbeforeprint", "onbeforeunload", "onhashchange", "onlanguagechange", "onmessage", "onmessageerror", "onoffline", "ononline", "onpagehide", "onpageshow", "onpopstate", "onrejectionhandled", "onstorage", "onunhandledrejection", "onunload", "alert", "atob", "blur", "btoa", "cancelAnimationFrame", "cancelIdleCallback", "captureEvents", "clearInterval", "clearTimeout", "close", "confirm", "createImageBitmap", "fetch", "find", "focus", "getComputedStyle", "getSelection", "matchMedia", "moveBy", "moveTo", "open", "postMessage", "print", "prompt", "queueMicrotask", "releaseEvents", "requestAnimationFrame", "requestIdleCallback", "resizeBy", "resizeTo", "scroll", "scrollBy", "scrollTo", "setInterval", "setTimeout", "stop", "webkitCancelAnimationFrame", "webkitRequestAnimationFrame", "chrome", "caches", "ondevicemotion", "ondeviceorientation", "ondeviceorientationabsolute", "originAgentCluster", "cookieStore", "showDirectoryPicker", "showOpenFilePicker", "showSaveFilePicker", "speechSynthesis", "onpointerrawupdate", "trustedTypes", "crossOriginIsolated", "openDatabase", "webkitRequestFileSystem", "webkitResolveLocalFileSystemURL"]);
    for (const key of Object.keys(window)) {

You most likely want to examine the documentation for T-SQL's CAST and CONVERT functions, located in the documentation here: http://msdn.microsoft.com/en-US/library/ms187928(v=SQL.90).aspx

You will then use one of those functions in your T-SQL query to convert the [idate] column from the database into the datetime format of your liking in the output.

ISLE (InstallShield Limited Edition) is the "replacement" of the Visual Studio Setup and Deploy project, but many users think Microsoft took wrong step with removing .vdproj support from Visual Studio 2012 (and later ones) and supporting third-party company software.

Many people asked for returning it back (Bring back the basic setup and deployment project type Visual Studio Installer), but Microsoft is deaf to our voices... really sad.

As WiX is really complicated, I think it is worth to try some free installation systems - NSIS or Inno Setup. Both are scriptable and easy to learn - but powerful as original SADP.

I have created a really nice Visual Studio extension for NSIS and Inno Setup with many features (intellisense, syntax highlighting, navigation bars, compilation directly from Visual Studio, etc.). You can try it at www.visual-installer.com (sorry for self promo :)

Download Inno Setup (jrsoftware.org/isdl.php) or NSIS (nsis.sourceforge.net/Download) and install V&I (unsigned-softworks.sk/visual-installer/downloads.html).

All installers are simple Next/Next/Next...

In Visual Studio, select menu File -> New -> Project, choose NSISProject or Inno Setup, and a new project will be created (with full sources).

Try running the following query:

repair table <table_name>;

I had the same issue and it solved me the problem.

On windows, I just add multiple batch files for different JDK versions to the Maven bin folder like this:

mvn11.cmd

@echo off
setlocal
set "JAVA_HOME=path\to\jdk11"
set "path=%JAVA_HOME%;%path%"
mvn %*

then you can use mvn11 to run Maven in the specified JDK.

Short answer: you can't. Use MSIEXEC /x

Long answer: When you run the MSI file directly at the command line, all that's happening is that it runs MSIEXEC for you. This association is stored in the registry. You can see a list of associations by (in Windows Explorer) going to Tools / Folder Options / File Types.

For example, you can run a .DOC file from the command line, and WordPad or WinWord will open it for you.

If you look in the registry under HKEY_CLASSES_ROOT\.msi, you'll see that .MSI files are associated with the ProgID "Msi.Package". If you look in HKEY_CLASSES_ROOT\Msi.Package\shell\Open\command, you'll see the command line that Windows actually uses when you "run" a .MSI file.

This question has been answered, but maybe this might someone else coming here.

I also had an issue where this is undefined, when I was foolishly trying to destructure the methods of a class when initialising it:

import MyClass from "./myClass"

// 'this' is not defined here:
const { aMethod } = new MyClass()
aMethod() // error: 'this' is not defined

// So instead, init as you would normally:
const myClass = new MyClass()
myClass.aMethod() // OK

Your script is timing out. Take a look at the set_time_limit() function to up the execution time. Or profile the script to make it run faster :)

Adding new remote

git remote add upstream https://github.com/example-org/example-repo.git

git remote -vv

Fetch form multiple locations

git fetch --all

git push -u upstream/dev

$("#YOUR-BUTTON").on('click', function(e) {
   e.preventDefault();
   $('html, body').animate({

     }, 300);
});

"ModelState.IsValid" tells you that the model is consumed by the view (i.e. PaymentAdviceEntity) is satisfy all types of validation or not specified in the model properties by DataAnotation.

In this code the view does not bind any model properties. So if you put any DataAnotations or validation in model (i.e. PaymentAdviceEntity). then the validations are not satisfy. say if any properties in model is Name which makes required in model.Then the value of the property remains blank after post.So the model is not valid (i.e. ModelState.IsValid returns false). You need to remove the model level validations.

The way I do it: I store the latitude and longitude and then I have a third column which is a automatic derived geography type of the 1st two columns. The table looks like this:

CREATE TABLE [dbo].[Geopoint]
(
    [GeopointId] BIGINT NOT NULL PRIMARY KEY IDENTITY, 
    [Latitude] float NOT NULL, 
    [Longitude] float NOT NULL, 
    [ts] ROWVERSION NOT NULL, 
    [GeographyPoint]  AS ([geography]::STGeomFromText(((('POINT('+CONVERT([varchar](20),[Longitude]))+' ')+CONVERT([varchar](20),[Latitude]))+')',(4326))) 
)

This gives you the flexibility of spatial queries on the geoPoint column and you can also retrieve the latitude and longitude values as you need them for display or extracting for csv purposes.

I had the same question before visiting this thread. For me the sys.stdout.write worked only if I properly flush the buffer i.e.

for x in range(10):
    sys.stdout.write('\r'+str(x))
    sys.stdout.flush()

Without flushing, the result is printed only at the end out the script

Since python 3.6 you can use fstring :

>>> length = 1
>>> print(f'length = {length:03}')
length = 001

It's pretty simple.

HTML:

<img id="theImage" src="yourImage.png">
<a id="showImage">Show image</a>

JavaScript:

document.getElementById("showImage").onclick = function() {
    document.getElementById("theImage").style.visibility = "visible";
}

CSS:

#theImage { visibility: hidden; }

In oracle db there is a trick for casting int to float (I suppose, it should also work in mysql):

select myintfield + 0.0 as myfloatfield from mytable

While @Heximal's answer works, I don't personally recommend it.

This is because it uses implicit casting. Although you didn't type CAST, either the SUM() or the 0.0 need to be cast to be the same data-types, before the + can happen. In this case the order of precedence is in your favour, and you get a float on both sides, and a float as a result of the +. But SUM(aFloatField) + 0 does not yield an INT, because the 0 is being implicitly cast to a FLOAT.

I find that in most programming cases, it is much preferable to be explicit. Don't leave things to chance, confusion, or interpretation.

If you want to be explicit, I would use the following.

CAST(SUM(sl.parts) AS FLOAT) * cp.price
-- using MySQL CAST FLOAT  requires 8.0

You can try the following to see what happens...

CAST(SUM(sl.parts) AS NUMERIC(10,4)) * CAST(cp.price AS NUMERIC(10,4))

If you want the conversion to always succeed, probably the best way to convert the string would be to consider "1" as true and anything else as false (as Kevin does). If you wanted the conversion to fail if anything other than "1" or "0" is returned, then the following would suffice (you could put it in a helper method):

if (returnValue == "1")
{
    return true;
}
else if (returnValue == "0")
{
    return false;
}
else
{
    throw new FormatException("The string is not a recognized as a valid boolean value.");
}

Slightly alternative solution to @jpp's but outputting a YearMonth string:

df['YearMonth'] = pd.to_datetime(df['Date']).apply(lambda x: '{year}-{month}'.format(year=x.year, month=x.month))

res = df.groupby('YearMonth')['Values'].sum()

SEL is a type that represents a selector in Objective-C. The @selector() keyword returns a SEL that you describe. It's not a function pointer and you can't pass it any objects or references of any kind. For each variable in the selector (method), you have to represent that in the call to @selector. For example:

-(void)methodWithNoParameters;
SEL noParameterSelector = @selector(methodWithNoParameters);

-(void)methodWithOneParameter:(id)parameter;
SEL oneParameterSelector = @selector(methodWithOneParameter:); // notice the colon here

-(void)methodWIthTwoParameters:(id)parameterOne and:(id)parameterTwo;
SEL twoParameterSelector = @selector(methodWithTwoParameters:and:); // notice the parameter names are omitted

Selectors are generally passed to delegate methods and to callbacks to specify which method should be called on a specific object during a callback. For instance, when you create a timer, the callback method is specifically defined as:

-(void)someMethod:(NSTimer*)timer;

So when you schedule the timer you would use @selector to specify which method on your object will actually be responsible for the callback:

@implementation MyObject

-(void)myTimerCallback:(NSTimer*)timer
{
    // do some computations
    if( timerShouldEnd ) {
      [timer invalidate];
    }
}

@end

// ...

int main(int argc, const char **argv)
{
    // do setup stuff
    MyObject* obj = [[MyObject alloc] init];
    SEL mySelector = @selector(myTimerCallback:);
    [NSTimer scheduledTimerWithTimeInterval:30.0 target:obj selector:mySelector userInfo:nil repeats:YES];
    // do some tear-down
    return 0;
}

In this case you are specifying that the object obj be messaged with myTimerCallback every 30 seconds.

I can also use

show errors;

In sql worksheet.

If you are on a mysql server and if you don't mind loosing your tables, you can use a simple query to delete multiple tables at once:

SET foreign_key_checks = 0;
DROP TABLE IF EXISTS table_a,table_b,table_c,table_etc;
SET foreign_key_checks = 1;

In this way it doesn't matter in what order you use the table in you query.

If anybody is going to say something about the fact that this is not a good solution if you have a database with many tables: I agree!

DBCC CHECKIDENT ( ‘databasename.dbo.orders’,RESEED, 999) you can change any identity column number with this command,and also you can start that field number from every number you want.for example in my command i ask to start from 1000 (999+1) hope that it would be enough...good luck

This is similiarly to @RobMcAfee except that I use magic number instead of 2 dimensional array.

int rand7() {
    int m = 1203068;
    int r = (m >> (rand5() - 1) * 5 + rand5() - 1) & 7;

    return (r > 0) ? r : rand7();
}

teteArg, thank you so much. Just an added information so, everyone bumping into this question will be able to understand why.

What teteArg said is indicated on the Spring Boot Common Properties: http://docs.spring.io/spring-boot/docs/current/reference/html/common-application-properties.html

Apparently, spring.jpa.hibernate.naming.strategy is not a supported property for Spring JPA implementation using Hibernate 5.

NOTE The question in the bounty by @WilliamJockusch and the original question are different.

This answer is about StackOverflow's in the general case of third-party libraries and what you can/can't do with them. If you're looking about the special case with XslTransform, see the accepted answer.

Stack overflows happen because the data on the stack exceeds a certain limit (in bytes). The details of how this detection works can be found here.

I'm wondering if there is a general way to track down StackOverflowExceptions. In other words, suppose I have infinite recursion somewhere in my code, but I have no idea where. I want to track it down by some means that is easier than stepping through code all over the place until I see it happening. I don't care how hackish it is.

As I mentioned in the link, detecting a stack overflow from static code analysis would require solving the halting problem which is undecidable. Now that we've established that there is no silver bullet, I can show you a few tricks that I think helps track down the problem.

I think this question can be interpreted in different ways, and since I'm a bit bored :-), I'll break it down into different variations.

Detecting a stack overflow in a test environment

Basically the problem here is that you have a (limited) test environment and want to detect a stack overflow in an (expanded) production environment.

Instead of detecting the SO itself, I solve this by exploiting the fact that the stack depth can be set. The debugger will give you all the information you need. Most languages allow you to specify the stack size or the max recursion depth.

Basically I try to force a SO by making the stack depth as small as possible. If it doesn't overflow, I can always make it bigger (=in this case: safer) for the production environment. The moment you get a stack overflow, you can manually decide if it's a 'valid' one or not.

To do this, pass the stack size (in our case: a small value) to a Thread parameter, and see what happens. The default stack size in .NET is 1 MB, we're going to use a way smaller value:

class StackOverflowDetector
{
    static int Recur()
    {
        int variable = 1;
        return variable + Recur();
    }

    static void Start()
    {
        int depth = 1 + Recur();
    }

    static void Main(string[] args)
    {
        Thread t = new Thread(Start, 1);
        t.Start();
        t.Join();
        Console.WriteLine();
        Console.ReadLine();
    }
}

Note: we're going to use this code below as well.

Once it overflows, you can set it to a bigger value until you get a SO that makes sense.

Creating exceptions before you SO

The StackOverflowException is not catchable. This means there's not much you can do when it has happened. So, if you believe something is bound to go wrong in your code, you can make your own exception in some cases. The only thing you need for this is the current stack depth; there's no need for a counter, you can use the real values from .NET:

class StackOverflowDetector
{
    static void CheckStackDepth()
    {
        if (new StackTrace().FrameCount > 10) // some arbitrary limit
        {
            throw new StackOverflowException("Bad thread.");
        }
    }

    static int Recur()
    {
        CheckStackDepth();
        int variable = 1;
        return variable + Recur();
    }

    static void Main(string[] args)
    {
        try
        {
            int depth = 1 + Recur();
        }
        catch (ThreadAbortException e)
        {
            Console.WriteLine("We've been a {0}", e.ExceptionState);
        }
        Console.WriteLine();
        Console.ReadLine();
    }
}

Note that this approach also works if you are dealing with third-party components that use a callback mechanism. The only thing required is that you can intercept some calls in the stack trace.

Detection in a separate thread

You explicitly suggested this, so here goes this one.

You can try detecting a SO in a separate thread.. but it probably won't do you any good. A stack overflow can happen fast, even before you get a context switch. This means that this mechanism isn't reliable at all... I wouldn't recommend actually using it. It was fun to build though, so here's the code :-)

class StackOverflowDetector
{
    static int Recur()
    {
        Thread.Sleep(1); // simulate that we're actually doing something :-)
        int variable = 1;
        return variable + Recur();
    }

    static void Start()
    {
        try
        {
            int depth = 1 + Recur();
        }
        catch (ThreadAbortException e)
        {
            Console.WriteLine("We've been a {0}", e.ExceptionState);
        }
    }

    static void Main(string[] args)
    {
        // Prepare the execution thread
        Thread t = new Thread(Start);
        t.Priority = ThreadPriority.Lowest;

        // Create the watch thread
        Thread watcher = new Thread(Watcher);
        watcher.Priority = ThreadPriority.Highest;
        watcher.Start(t);

        // Start the execution thread
        t.Start();
        t.Join();

        watcher.Abort();
        Console.WriteLine();
        Console.ReadLine();
    }

    private static void Watcher(object o)
    {
        Thread towatch = (Thread)o;

        while (true)
        {
            if (towatch.ThreadState == System.Threading.ThreadState.Running)
            {
                towatch.Suspend();
                var frames = new System.Diagnostics.StackTrace(towatch, false);
                if (frames.FrameCount > 20)
                {
                    towatch.Resume();
                    towatch.Abort("Bad bad thread!");
                }
                else
                {
                    towatch.Resume();
                }
            }
        }
    }
}

Run this in the debugger and have fun of what happens.

Using the characteristics of a stack overflow

Another interpretation of your question is: "Where are the pieces of code that could potentially cause a stack overflow exception?". Obviously the answer of this is: all code with recursion. For each piece of code, you can then do some manual analysis.

It's also possible to determine this using static code analysis. What you need to do for that is to decompile all methods and figure out if they contain an infinite recursion. Here's some code that does that for you:

// A simple decompiler that extracts all method tokens (that is: call, callvirt, newobj in IL)
internal class Decompiler
{
    private Decompiler() { }

    static Decompiler()
    {
        singleByteOpcodes = new OpCode[0x100];
        multiByteOpcodes = new OpCode[0x100];
        FieldInfo[] infoArray1 = typeof(OpCodes).GetFields();
        for (int num1 = 0; num1 < infoArray1.Length; num1++)
        {
            FieldInfo info1 = infoArray1[num1];
            if (info1.FieldType == typeof(OpCode))
            {
                OpCode code1 = (OpCode)info1.GetValue(null);
                ushort num2 = (ushort)code1.Value;
                if (num2 < 0x100)
                {
                    singleByteOpcodes[(int)num2] = code1;
                }
                else
                {
                    if ((num2 & 0xff00) != 0xfe00)
                    {
                        throw new Exception("Invalid opcode: " + num2.ToString());
                    }
                    multiByteOpcodes[num2 & 0xff] = code1;
                }
            }
        }
    }

    private static OpCode[] singleByteOpcodes;
    private static OpCode[] multiByteOpcodes;

    public static MethodBase[] Decompile(MethodBase mi, byte[] ildata)
    {
        HashSet<MethodBase> result = new HashSet<MethodBase>();

        Module module = mi.Module;

        int position = 0;
        while (position < ildata.Length)
        {
            OpCode code = OpCodes.Nop;

            ushort b = ildata[position++];
            if (b != 0xfe)
            {
                code = singleByteOpcodes[b];
            }
            else
            {
                b = ildata[position++];
                code = multiByteOpcodes[b];
                b |= (ushort)(0xfe00);
            }

            switch (code.OperandType)
            {
                case OperandType.InlineNone:
                    break;

                        {
                            result.Add((MethodBase)module.ResolveMember(methodId, mi.DeclaringType.GetGenericArguments(), Type.EmptyTypes));
                        }
                        else
                        {
                            result.Add((MethodBase)module.ResolveMember(methodId, mi.DeclaringType.GetGenericArguments(), mi.GetGenericArguments()));
                        }
                    }
                    catch { } 
                    break;


                default:

class StackOverflowDetector
{
    // This method will be found:
    static int Recur()
    {
        CheckStackDepth();
        int variable = 1;
        return variable + Recur();
    }

    static void Main(string[] args)
    {
        RecursionDetector();
        Console.WriteLine();
        Console.ReadLine();
    }

    static void RecursionDetector()
    {
        // First decompile all methods in the assembly:
        Dictionary<MethodBase, MethodBase[]> calling = new Dictionary<MethodBase, MethodBase[]>();
        var assembly = typeof(StackOverflowDetector).Assembly;

        foreach (var type in assembly.GetTypes())
        {
            foreach (var member in type.GetMembers(BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.Static | BindingFlags.Instance).OfType<MethodBase>())
            {
                var body = member.GetMethodBody();
                if (body!=null)
                {
                    var bytes = body.GetILAsByteArray();
                    if (bytes != null)
                    {
                        // Store all the calls of this method:
                        var calls = Decompiler.Decompile(member, bytes);
                        calling[member] = calls;
                    }
                }

        }

        // Check every method:
        foreach (var method in calling.Keys)
        {
            // If method A -> ... -> method A, we have a possible infinite recursion
            CheckRecursion(method, calling, new HashSet<MethodBase>());
        }
    }

Now, the fact that a method cycle contains recursion, is by no means a guarantee that a stack overflow will happen - it's just the most likely precondition for your stack overflow exception. In short, this means that this code will determine the pieces of code where a stack overflow can occur, which should narrow down most code considerably.

Yet other approaches

There are some other approaches you can try that I haven't described here.

1. Handling the stack overflow by hosting the CLR process and handling it. Note that you still cannot 'catch' it.
2. Changing all IL code, building another DLL, adding checks on recursion. Yes, that's quite possible (I've implemented it in the past :-); it's just difficult and involves a lot of code to get it right.
3. Use the .NET profiling API to capture all method calls and use that to figure out stack overflows. For example, you can implement checks that if you encounter the same method X times in your call tree, you give a signal. There's a project here that will give you a head start.

Here is a really simple way to do it :)

Clone the repository

git clone <repository_url>

List all branches

git branch -a 

Checkout the branch that you want

git checkout <name_of_branch>

Main Example

The example below will run myfile.sql on database mydatabase using schema myschema.

psql "dbname=mydatabase options=--search_path=myschema" -a -f myfile.sql

The way this works is the first argument to the psql command is the dbname argument. The docs mention a connection string can be provided.

If this parameter contains an = sign or starts with a valid URI prefix (postgresql:// or postgres://), it is treated as a conninfo string

The dbname keyword specifies the database to connect to and the options keyword lets you specify command-line options to send to the server at connection startup. Those options are detailed in the server configuration chapter. The option we are using to select the schema is search_path.

Another Example

The example below will connect to host myhost on database mydatabase using schema myschema. The = special character must be url escaped with the escape sequence %3D.

psql postgres://myuser@myhost?options=--search_path%3Dmyschema

In this public Github repo https://github.com/boskjoett/BasicAuthWebApi you can see a simple example of a ASP.NET Core 2.2 web API with endpoints protected by Basic Authentication.

As of HTML5, the foreground colors of hyperlinks, among other things, are on track for standardization in the form of guidelines for expected default rendering behavior. In particular, taken from the section Phrasing content, the recommended default colors for unvisited and visited hyperlinks are the following:

:link { color: #0000EE; }
:visited { color: #551A8B; }

Notice that there is no recommended default for active hyperlinks (:link:active, :visited:active), however.

You can use these default colors and reasonably expect them to work. But keep in mind that a browser is free to ignore any or all of these guidelines, as it is never required to follow them. It is, however, recommended for a consistent user experience across browsers (which is how "expected" is defined in this context), so chances are that these colors will correspond to the defaults for most browsers. At worst, they still serve as reasonable approximations of the actual values.

In particular, the default unvisited and visited link colors in the latest versions of Firefox and Chrome are consistent with the above guidelines, but recent versions of IE report different values: unvisited links are rgb(0, 102, 204), or #0066CC, and visited links are rgb(128, 0, 128), or #800080. Older versions of Firefox (and possibly Safari/Chrome) had different defaults as well. Those are older versions, however; the main outlier today that I am aware of is IE. No word yet on whether this will change in Project Spartan — currently it still reflects the same values as the latest version of IE.

If you are looking for a standardized color scheme that is used by all browsers rather than suggested by HTML5, then there isn't one. Neither is there a way to revert to a browser's default value for a particular property on a particular element using pure CSS. You will have to either use the colors suggested by HTML5, or devise your own color scheme and use that instead. Either of these options will take precedence over a browser's defaults, regardless of browser.

If in doubt, you can always use the about:blank technique I described before to sniff out the default colors, as it remains applicable today. You can use this to sniff the active link color in all browsers, for example; in the latest version of Firefox (29 as of this update), it's rgb(238, 0, 0), or #EE0000.

This little and simple trick I just learnt may help someone trying to avoid :before or :after pseudo elements altogether (for whatever reason) in changing text on hover. You can add both texts in the HTML, but vary the CSS 'display' property based on hover. Assuming the second text 'Add' has a class named 'add-label'; here is a little modification:

span.add-label{
 display:none;
}
.item:hover span.align{
 display:none;
}
.item:hover span.add-label{
 display:block;
}

Here is a demonstration on codepen: https://codepen.io/ifekt/pen/zBaEVJ

df['variance'] = df.loc[:,['budget','actual']].sum(axis=1)

The @ symbol allows you to use reserved word. For example:

int @class = 15;

The above works, when the below wouldn't:

int class = 15;

First check To see how many aliases you have and what are they, you can initiate this command git remote -v

Then see in which repository you are in then try git remote set-url --add [Then your repositpory link] git push -u origin master

I am tempted to squeeze in my favourite solution. The resulting table will consist of 2 columns: PosIdx for position of the found integer; and Value in integer.

create function FnSplitToTableInt
(
    @param nvarchar(4000)
)
returns table as
return
    with Numbers(Number) as 
    (
        select 1 
        union all 
        select Number + 1 from Numbers where Number < 4000
    ),
    Found as
    (
        select 
            Number as PosIdx,
            convert(int, ltrim(rtrim(convert(nvarchar(4000), 
                substring(@param, Number, 
                charindex(N',' collate Latin1_General_BIN, 
                @param + N',', Number) - Number))))) as Value
        from   
            Numbers 
        where  
            Number <= len(@param)
        and substring(N',' + @param, Number, 1) = N',' collate Latin1_General_BIN
    )
    select 
        PosIdx, 
        case when isnumeric(Value) = 1 
            then convert(int, Value) 
            else convert(int, null) end as Value 
    from 
        Found

It works by using recursive CTE as the list of positions, from 1 to 100 by default. If you need to work with string longer than 100, simply call this function using 'option (maxrecursion 4000)' like the following:

select * from FnSplitToTableInt
(
    '9, 8, 7, 6, 5, 4, 3, 2, 1, 0, ' + 
    '9, 8, 7, 6, 5, 4, 3, 2, 1, 0, ' +
    '9, 8, 7, 6, 5, 4, 3, 2, 1, 0, ' +
    '9, 8, 7, 6, 5, 4, 3, 2, 1, 0, ' +
    '9, 8, 7, 6, 5, 4, 3, 2, 1, 0'
) 
option (maxrecursion 4000)

I spent hours trying to convert a windows form listbox ToString value to a standard string so that I could use it with fstream to output to a txt file. My Visual Studio didn't come with marshal header files which several answers I found said to use. After so much trial and error I finally found a solution to the problem that just uses System::Runtime::InteropServices:

void MarshalString ( String ^ s, string& os ) {
   using namespace Runtime::InteropServices;
   const char* chars = 
      (const char*)(Marshal::StringToHGlobalAnsi(s)).ToPointer();
   os = chars;
   Marshal::FreeHGlobal(IntPtr((void*)chars));
}

//this is the code to use the function:
scheduleBox->SetSelected(0,true);
string a = "test";
String ^ c = gcnew String(scheduleBox->SelectedItem->ToString());
MarshalString(c, a);
filestream << a;

And here is the MSDN page with the example: http://msdn.microsoft.com/en-us/library/1b4az623(v=vs.80).aspx

I know it's a pretty simple solution but this took me HOURS of troubleshooting and visiting several forums to finally find something that worked.

[label setText:@"Value: %.2f", myNumber];

You can easily create a timer functionality by using setInterval.Below is the code which you can use it to create the timer.

http://jsfiddle.net/ayyadurai/GXzhZ/1/

window.onload = function() {_x000D_
  var minute = 5;_x000D_
  var sec = 60;_x000D_
  setInterval(function() {_x000D_
    document.getElementById("timer").innerHTML = minute + " : " + sec;_x000D_
    sec--;_x000D_
    if (sec == 00) {_x000D_
      minute --;_x000D_
      sec = 60;_x000D_
      if (minute == 0) {_x000D_
        minute = 5;_x000D_
      }_x000D_
    }_x000D_
  }, 1000);_x000D_
}

Registration closes in <span id="timer">05:00<span> minutes!

var object = { "a": 1, "b": 2};_x000D_
$.each(object, function(key, value){_x000D_
  console.log(key + ": " + object[key]);_x000D_
});

There is a lot of confusion about IdentityDbContext, a quick search in Stackoverflow and you'll find these questions:
" Why is Asp.Net Identity IdentityDbContext a Black-Box?

Based on the source code if we want to merge IdentityDbContext with our DbContext we have two options:

First Option:
Create a DbContext which inherits from IdentityDbContext and have access to the classes.

   public class ApplicationDbContext 
    : IdentityDbContext
{
    public ApplicationDbContext()
        : base("DefaultConnection")
    {
    }

    static ApplicationDbContext()
    {
        Database.SetInitializer<ApplicationDbContext>(new ApplicationDbInitializer());
    }

    public static ApplicationDbContext Create()
    {
        return new ApplicationDbContext();
    }

    // Add additional items here as needed
}

Extra Notes:

1) We can also change asp.net Identity default table names with the following solution:

    public class ApplicationDbContext : IdentityDbContext
    {    
        public ApplicationDbContext(): base("DefaultConnection")
        {
        }

        protected override void OnModelCreating(System.Data.Entity.DbModelBuilder modelBuilder)
        {
            base.OnModelCreating(modelBuilder);
            modelBuilder.Entity<IdentityUser>().ToTable("user");
            modelBuilder.Entity<ApplicationUser>().ToTable("user");

            modelBuilder.Entity<IdentityRole>().ToTable("role");
            modelBuilder.Entity<IdentityUserRole>().ToTable("userrole");
            modelBuilder.Entity<IdentityUserClaim>().ToTable("userclaim");
            modelBuilder.Entity<IdentityUserLogin>().ToTable("userlogin");
        }
    }

2) Furthermore we can extend each class and add any property to classes like 'IdentityUser', 'IdentityRole', ...

    public class ApplicationRole : IdentityRole<string, ApplicationUserRole>
{
    public ApplicationRole() 
    {
        this.Id = Guid.NewGuid().ToString();
    }

    public ApplicationRole(string name)
        : this()
    {
        this.Name = name;
    }

    // Add any custom Role properties/code here
}


// Must be expressed in terms of our custom types:
public class ApplicationDbContext 
    : IdentityDbContext<ApplicationUser, ApplicationRole, 
    string, ApplicationUserLogin, ApplicationUserRole, ApplicationUserClaim>
{
    public ApplicationDbContext()
        : base("DefaultConnection")
    {
    }

    static ApplicationDbContext()
    {
        Database.SetInitializer<ApplicationDbContext>(new ApplicationDbInitializer());
    }

    public static ApplicationDbContext Create()
    {
        return new ApplicationDbContext();
    }

    // Add additional items here as needed
}

To save time we can use AspNet Identity 2.0 Extensible Project Template to extend all the classes.

Second Option:(Not recommended)
We actually don't have to inherit from IdentityDbContext if we write all the code ourselves.
So basically we can just inherit from DbContext and implement our customized version of "OnModelCreating(ModelBuilder builder)" from the IdentityDbContext source code

You have to use the date part fetching method:

SELECT * FROM testbed WHERE start_date  ::date >= to_date('2012-09-08' ,'YYYY-MM-DD') and date::date <= to_date('2012-10-09' ,'YYYY-MM-DD')

To reflect the status as of 2015:

Behaviorally both 400 and 422 response codes will be treated the same by clients and intermediaries, so it actually doesn't make a concrete difference which you use.

However I would expect to see 400 currently used more widely, and furthermore the clarifications that the HTTPbis spec provides make it the more appropriate of the two status codes:

• The HTTPbis spec clarifies the intent of 400 to not be solely for syntax errors. The broader phrase "indicates that the server cannot or will not process the request due to something which is perceived to be a client error" is now used.
• 422 is specifically a WebDAV extension, and is not referenced in RFC 2616 or in the newer HTTPbis specification.

For context, HTTPbis is a revision of the HTTP/1.1 spec that attempts to clarify areas that were unclear or inconsistent. Once it has reached approved status it will supersede RFC2616.

First, you don't need the .class files if they are compiled from your .java classes.

To import your files, you need to create an empty Java project. They you either import them one by one (New -> File -> Advanced -> Link file) or directly copy them into their corresponding folder/package and refresh the project.

An extra pair of rabbits' ears should do the trick.

start "" "C:\Program...

START regards the first quoted parameter as the window-title, unless it's the only parameter - and any switches up until the executable name are regarded as START switches.

I think its not working, because you z-index property not applied on pdf(any outside object). So when you add any control in PDF view boundary,its appear behind of pdf view.

buf.delete(0,  buf.length());

You should just use something like:

YourModel.update_all(
  ActiveRecord::Base.send(:sanitize_sql_for_assignment, {:value => "'wow'"})
)

That would do the trick. Using the ActiveRecord::Base#send method to invoke the sanitize_sql_for_assignment makes the Ruby (at least the 1.8.7 version) skip the fact that the sanitize_sql_for_assignment is actually a protected method.

v-bind and v-on are two frequently used directives in vuejs html template. So they provided a shorthand notation for the both of them as follows:

You can replace v-on: with @

v-on:click='someFunction'

as:

@click='someFunction'

Another example:

v-on:keyup='someKeyUpFunction'

as:

@keyup='someKeyUpFunction'

Similarly, v-bind with :

v-bind:href='var1'

Can be written as:

:href='var1'

Hope it helps!

Make sure you don't have a minSdkVersion set in your build.gradle with a value higher than 8. If you don't specify it at all, it's supposed to use the value in your AndroidManfiest.xml, which seems to already be properly set.

HTML

<div id="myDiv" style="display:none;" class="answer_list" >WELCOME</div>
<input type="button" name="answer" onclick="ShowDiv()" />

JavaScript

function ShowDiv() {
    document.getElementById("myDiv").style.display = "";
}

Or if you wanted to use jQuery with a nice little animation:

<input id="myButton" type="button" name="answer" />

$('#myButton').click(function() {
  $('#myDiv').toggle('slow', function() {
    // Animation complete.
  });
});

In my case, it goes well after I installed CMake in my system:)

sudo pacman -S cmake

for manjaro operating system.

I asked in #machomebrew and learned that you can switch between versions using brew switch.

$ brew switch libfoo mycopy 

to get version mycopy of libfoo.

Is there maybe a trigger on the table setting it back?

It cause eclipse kepler SR1 does not support new Java™ 8 language enhancements like lambda expression.

From information here: http://www.eclipse.org/downloads/java8/
I think you should use kepler SR2 with support plugin, or change to Eclipse Luna.

It looks as though it's not an array but an arbitrary object. If you have control over the PHP serialization, you might be able to change that.

As raina77ow pointed out, one way to do this in PHP would be by replacing something like this:

json_encode($something) 

with something like:

json_encode(array_values($something))

But don't ignore the other answers here about Object.keys. They should also accomplish what you want if you don't have the ability or the desire to change the serialization of your object.

try this:

Sub test()

With Application.WorksheetFunction
    Cells(.CountA(Columns("A:A")) + 1, 1).Select
End With

End Sub

Hope this works for you.

@echo off
SETLOCAL ENABLEDELAYEDEXPANSION
SET old=Vacation2010
SET new=December
for /f "tokens=*" %%f in ('dir /b *.jpg') do (
  SET newname=%%f
  SET newname=!newname:%old%=%new%!
  move "%%f" "!newname!"
)

What this does is it loops over all .jpg files in the folder where the batch file is located and replaces the Vacation2010 with December inside the filenames.

Use jQuery

Look how easy it would be if you did.

Example:

$('#td1').html('hello world');

If you would like to insert multiple values lets say from multiple inputs that have different post values but the same table to insert into then simply use:

mysql_query("INSERT INTO `table` (a,b,c,d,e,f,g) VALUES 
('$a','$b','$c','$d','$e','$f','$g'),
('$a','$b','$c','$d','$e','$f','$g'),
('$a','$b','$c','$d','$e','$f','$g')")
or die (mysql_error()); // Inserts 3 times in 3 different rows

From this: http://weblogs.sqlteam.com/peterl/archive/2008/06/19/How-to-change-authentication-mode-in-SQL-Server.aspx

One can catch that you may change it through windows registry key

(SQLEXPRESS instance):

"Software\Microsoft\Microsoft SQL Server\SQLEXPRESS\LoginMode" = 2

... and restart service

If there may be empty trailing spaces, probably there isn't better solution. COALESCE is just for problems like yours.

In contrast to what the accepted answer proposes, the documentation says that for JSONArray() you must use put(value) no add(value).

The simplest solution would be to add the following code on the top of the file. And than you can use all full Chrome console api as you would normally.

 console = chrome.extension.getBackgroundPage().console;
// for instance, console.assert(1!=1) will return assertion error
// console.log("msg") ==> prints msg
// etc

How to change commits deeper in history

Since history in Git is immutable, fixing anything but the most recent commit (commit which is not branch head) requires that the history is rewritten from the changed commit and forward.

You can use StGIT for that, initialize branch if necessary, uncommitting up to the commit you want to change, pop to it if necessary, make a change then refresh patch (with -e option if you want to correct commit message), then push everything and stg commit.

Or you can use rebase to do that. Create new temporary branch, rewind it to the commit you want to change using git reset --hard, change that commit (it would be top of current head), then rebase branch on top of changed commit, using git rebase --onto .

Or you can use git rebase --interactive, which allows various modifications like patch re-ordering, collapsing, ...

I think that should answer your question. However, note that if you have pushed code to a remote repository and people have pulled from it, then this is going to mess up their code histories, as well as the work they've done. So do it carefully.

Note that the above mentioned autoreload only works in IntelliJ if you manually save the changed file (e.g. using ctrl+s or cmd+s). It doesn't seem to work with auto-saving.

As of 2017, WebKit announces support for WebRTC on Safari

Now you can access them with video and standard javascript WebRTC

E.g.

var video = document.createElement('video');
video.setAttribute('playsinline', '');
video.setAttribute('autoplay', '');
video.setAttribute('muted', '');
video.style.width = '200px';
video.style.height = '200px';

/* Setting up the constraint */
var facingMode = "user"; // Can be 'user' or 'environment' to access back or front camera (NEAT!)
var constraints = {
  audio: false,
  video: {
   facingMode: facingMode
  }
};

/* Stream it to video element */
navigator.mediaDevices.getUserMedia(constraints).then(function success(stream) {
  video.srcObject = stream;
});

Have a play with it.

If you want to append this css file to header you can do it using mounted() function of the vue file. See the example.
Note: Assume you can access the css file as http://www.yoursite/assets/styles/vendor.css in the browser.

mounted() {
        let style = document.createElement('link');
        style.type = "text/css";
        style.rel = "stylesheet";
        style.href = '/assets/styles/vendor.css';
        document.head.appendChild(style);
    }

Bootstrap 5 has changed the ml,mr,pl,pr classes, which no longer work if you're upgrading from a lower version. The l and r have now been replaced with s(...which is confusing) and e(east?) respectively.

From bootstrap website:

Where property is one of:

• m - for classes that set margin
• p - for classes that set padding

Where sides is one of:

• t - for classes that set margin-top or padding-top
• b - for classes that set margin-bottom or padding-bottom
• s - for classes that set margin-left or padding-left in LTR, margin-right or padding-right in RTL
• e - for classes that set margin-right or padding-right in LTR, margin-left or padding-left in RTL
• x - for classes that set both *-left and *-right
• y - for classes that set both *-top and *-bottom blank - for classes that set a margin or padding on all 4 sides of the element Where size is one of:

0 - for classes that eliminate the margin or padding by setting it to 0 1 - (by default) for classes that set the margin or padding to $spacer * .25 2 - (by default) for classes that set the margin or padding to $spacer * .5 3 - (by default) for classes that set the margin or padding to $spacer 4 - (by default) for classes that set the margin or padding to $spacer * 1.5 5 - (by default) for classes that set the margin or padding to $spacer * 3 auto - for classes that set the margin to auto (You can add more sizes by adding entries to the $spacers Sass map variable.)

I have made a workaround to solve this problem. Visit the below link for more details http://code-outofbox.blogspot.com/2015/07/java-prepared-statement-print-values.html

Solution:

// Initialize connection
PreparedStatement prepStmt = connection.prepareStatement(sql);

PreparedStatementHelper prepHelper = new PreparedStatementHelper(prepStmt);

// User prepHelper.setXXX(indx++, value);
// .....

try {
   Pattern pattern = Pattern.compile("\\?");
   Matcher matcher = pattern.matcher(sql);
   StringBuffer sb = new StringBuffer();
   int indx = 1;  // Parameter begin with index 1
   while (matcher.find()) {
 matcher.appendReplacement(sb, prepHelper.getParameter(indx++));
   }
   matcher.appendTail(sb);
   LOGGER.debug("Executing Query [" + sb.toString() + "] with Database[" + /*db name*/ + "] ...");
   } catch (Exception ex) {
    LOGGER.debug("Executing Query [" + sql + "] with Database[" +  /*db name*/+ "] ...");
}

As of git version 2.13, git supports conditional configuration includes. In this example we clone Company A's repos in ~/company_a directory, and Company B's repos in ~/company_b.

In your .gitconfig you can put something like this.

[includeIf "gitdir:~/company_a/"]
  path = .gitconfig-company_a
[includeIf "gitdir:~/company_b/"]
  path = .gitconfig-company_b

Example contents of .gitconfig-company_a

[user]
name = John Smith
email = [email protected]

Example contents of .gitconfig-company_b

[user]
name = John Smith
email = [email protected]

In the documentation it's stated: Use the prefix option together with the global option:

The prefix config defaults to the location where node is installed. On most systems, this is /usr/local. On windows, this is the exact location of the node.exe binary. On Unix systems, it's one level up, since node is typically installed at {prefix}/bin/node rather than {prefix}/node.exe.

When the global flag is set, npm installs things into this prefix. When it is not set, it uses the root of the current package, or the current working directory if not in a package already.

(Emphasis by them)

So in your root directory you could install with

npm install --prefix <path/to/prefix_folder> -g

and it will install the node_modules folder into the folder

<path/to/prefix_folder>/lib/node_modules

Using the "autofocus" attribute works to give input focus to the button by default. In fact clicking on any control within the form also gives focus to the form, a requirement for the form to react to the RETURN. So, the "autofocus" does that for you in case the user never clicked on any other control within the form.

So, the "autofocus" makes the crucial difference if the user never clicked on any of the form controls before hitting RETURN.

But even then, there are still 2 conditions to be met for this to work without JS:

a) you have to specify a page to go to (if left empty it wont work). In my example it is hello.php

b) the control has to be visible. You could conceivably move it off the page to hide, but you cannot use display:none or visibility:hidden. What I did, was to use inline style to just move it off the page to the left by 200px. I made the height 0px so that it does not take up space. Because otherwise it can still disrupt other controls above and below. Or you could float the element too.

<form action="hello.php" method="get">
  Name: <input type="text" name="name"/><br/>
  Pwd: <input type="password" name="password"/><br/>
  <div class="yourCustomDiv"/>
  <input autofocus type="submit" style="position:relative; left:-200px; height:0px;" />
</form>

TextView tv = new TextView(this);
tv.setText(String.valueOf(number));

or

tv.setText(""+number);

This is another solution:

def diff(a, b):
    xa = [i for i in set(a) if i not in b]
    xb = [i for i in set(b) if i not in a]
    return xa + xb

date under Mac OSX is slightly different.

For yesterday

date -v-1d +%F

For Last week

date -v-1w +%F

Go means, whatever SQL statements are written before it and after any earlier GO, will go to SQL server for processing.

Select * from employees;
GO    -- GO 1

update employees set empID=21 where empCode=123;
GO    -- GO 2

In the above example, statements before GO 1 will go to sql sever in a batch and then any other statements before GO 2 will go to sql server in another batch. So as we see it has separated batches.

I ran into the same error, when I just forgot to declare my custom component in my NgModule - check there, if the others solutions won't work for you.

You may use event handler serverclick as below

//cmdAction is the id of HTML button as below

<body>
    <form id="form1" runat="server">
        <button type="submit" id="cmdAction" text="Button1" runat="server">
            Button1
        </button>
    </form>
</body>

//cs code

public partial class _Default : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
                cmdAction.ServerClick += new EventHandler(submit_click);  
        }

        protected void submit_click(object sender, EventArgs e)
        {
            Response.Write("HTML Server Button Control");
        }
    }

Here is a way to add Parameters to the script if you used

pipeline.Commands.AddScript(Script);

This is with using an HashMap as paramaters the key being the name of the variable in the script and the value is the value of the variable.

pipeline.Commands.AddScript(script));
FillVariables(pipeline, scriptParameter);
Collection<PSObject> results = pipeline.Invoke();

And the fill variable method is:

private static void FillVariables(Pipeline pipeline, Hashtable scriptParameters)
{
  // Add additional variables to PowerShell
  if (scriptParameters != null)
  {
    foreach (DictionaryEntry entry in scriptParameters)
    {
      CommandParameter Param = new CommandParameter(entry.Key as String, entry.Value);
      pipeline.Commands[0].Parameters.Add(Param);
    }
  }
}

this way you can easily add multiple parameters to a script. I've also noticed that if you want to get a value from a variable in you script like so:

Object resultcollection = runspace.SessionStateProxy.GetVariable("results");

//results being the name of the v

you'll have to do it the way I showed because for some reason if you do it the way Kosi2801 suggests the script variables list doesn't get filled with your own variables.

Swift 3+ one liner to sum properties of objects

var totalSum = scaleData.map({$0.points}).reduce(0, +)

Where points is the property in my custom object scaleData that I am trying to reduce

Maybe using Where() before First() can help you, as my problem has been solved in this case.

var documentRow = _dsACL.Documents.Where(o => o.ID == id).FirstOrDefault();

The below command will delete all the local branches except master branch.

git branch | grep -v "master" | xargs git branch -D

The above command

1. list all the branches
2. From the list ignore the master branch and take the rest of the branches
3. delete the branch

in Haskell

import Data.Time.Clock.POSIX

main :: IO ()
main = print . floor =<< getPOSIXTime

in Go

import "time"
t := time.Unix()

in C

time(); // in time.h POSIX

// for Windows time.h
#define UNIXTIME(result)   time_t localtime; time(&localtime); struct tm* utctime = gmtime(&localtime); result = mktime(utctime);

in Swift

NSDate().timeIntervalSince1970 // or Date().timeIntervalSince1970

Try

> sum(v > 2 & v < 5)

Many different solutions for this problem. Most of them work as well. Another shortcut seems to be added as well:

Shift + alt + command ? + K

Will ask you to:

Are you sure you want to clean the build folder for “MyProject”?

This will delete all of the products and intermediate files in the build folder.

In most cases this would be enough to solve your problems.

UPDATE

As of Xcode 9 you'll be able to access the Derived Data folder by navigating to

File -> Project Settings

or if you use a Workspace:

File -> Workspace Settings

And press the arrow behind the path:

When you refer the chart to a defined Range, it plots all the points in that range, interpreting (for the sake of plotting) errors and blanks as null values.

You are given the option of leaving this as null (gap) or forcing it to zero value. But neither of these resizes the RANGE which the chart series data is pointing to. From what I gather, neither of these are suitable.

If you hide the entire row/column where the #N/A data exists, the chart should ignore these completely. You can do this manually by right-click | hide row, or by using the table AutoFilter. I think this is what you want to accomplish.

You can achieve the same using

<select [ngModel]="object">
  <option *ngFor="let object of objects;let i= index;" [value]="object.value" selected="i==0">{{object.name}}</option>
</select>

One way is to put all the nested loops into a function and return from the inner most loop incase of a need to break out of all loops.

function() 
{    
  for(int i=0; i<1000; i++)
  {
   for(int j=0; j<1000;j++)
   {
      if (condition)
        return;
   }
  }    
}

Table Positioning

Available Parameters

A table can easily be placed with the following parameters:

• h Place the float here, i.e., approximately at the same point it occurs in the source text (however, not exactly at the spot)
• t Position at the top of the page.
• b Position at the bottom of the page.
• p Put on a special page for floats only.
• ! Override internal parameters LaTeX uses for determining "good" float positions.
• H Places the float at precisely the location in the LATEX code. Requires the float package. This is somewhat equivalent to h!.

If you want to make use of H (or h!) for an exact positioning, make sure you got the float package correctly set up in the preamble:

\usepackage{float}
\restylefloat{table}

Example

If you want to place the table at the same page, either at the exact place or at least at the top of the page (what fits best for the latex engine), use the parameters h and t like this:

\begin{table}[ht]
    table content ...
\end{table}

No, if you are strictly speaking about regular expressions and not including some regular expression implementations that are actually context free grammars.

There is one limitation of regular expressions which makes it impossible to write a regex that matches all and only regexes. You cannot match implementations such as braces which are paired. Regexes use many such constructs, let's take [] as an example. Whenever there is an [ there must be a matching ], which is simple enough for a regex "\[.*\]".

What makes it impossible for regexes is that they can be nested. How can you write a regex that matches nested brackets? The answer is you can't without an infinitely long regex. You can match any number of nested parenthesis through brute force but you can't ever match an arbitrarily long set of nested brackets.

This capability is often referred to as counting, because you're counting the depth of the nesting. A regex by definition does not have the capability to count.

I ended up writing "Regular Expression Limitations" about this.

Look at this:

   <script>
function f(a){
  alert(typeof(a));
  if (a==null) alert('null');
  a?alert(true):alert(false);
}
</script>
                                          //return:
<button onclick="f()">nothing</button>    //undefined    null    false
<button onclick="f(null)">null</button>   //object       null    false
<button onclick="f('')">empty</button>    //string               false
<button onclick="f(0)">zero</button>      //number               false
<button onclick="f(1)">int</button>       //number               true
<button onclick="f('x')">str</button>     //string               true

import urllib
resource = urllib.urlopen("http://www.digimouth.com/news/media/2011/09/google-logo.jpg")
output = open("file01.jpg","wb")
output.write(resource.read())
output.close()

file01.jpg will contain your image.

Yesterday Date in PHP:

echo date("Y-m-d", strtotime("yesterday")); 

I think you should use python wheels for distribution instead of egg now.

Wheels are the new standard of python distribution and are intended to replace eggs. Support is offered in pip >= 1.4 and setuptools >= 0.8.

Maybe you have run into this problem: net::ERR_INSECURE_RESPONSE

You need to check the encryption algorithms supported by your server. For example for apache you can configure the cipher suite this way: cipher suite.

Which version of chrome are you running and what is the server serving your APIs?

This is an ideal situation for the join method

The join method is built exactly for these types of situations. You can join any number of DataFrames together with it. The calling DataFrame joins with the index of the collection of passed DataFrames. To work with multiple DataFrames, you must put the joining columns in the index.

The code would look something like this:

filenames = ['fn1', 'fn2', 'fn3', 'fn4',....]
dfs = [pd.read_csv(filename, index_col=index_col) for filename in filenames)]
dfs[0].join(dfs[1:])

With @zero's data, you could do this:

df1 = pd.DataFrame(np.array([
    ['a', 5, 9],
    ['b', 4, 61],
    ['c', 24, 9]]),
    columns=['name', 'attr11', 'attr12'])
df2 = pd.DataFrame(np.array([
    ['a', 5, 19],
    ['b', 14, 16],
    ['c', 4, 9]]),
    columns=['name', 'attr21', 'attr22'])
df3 = pd.DataFrame(np.array([
    ['a', 15, 49],
    ['b', 4, 36],
    ['c', 14, 9]]),
    columns=['name', 'attr31', 'attr32'])

dfs = [df1, df2, df3]
dfs = [df.set_index('name') for df in dfs]
dfs[0].join(dfs[1:])

     attr11 attr12 attr21 attr22 attr31 attr32
name                                          
a         5      9      5     19     15     49
b         4     61     14     16      4     36
c        24      9      4      9     14      9

Add this to the stylesheet:

table {
  border-collapse: collapse;
}

JSFiddle.

The reason why it behaves this way is actually described pretty well in the specification:

There are two distinct models for setting borders on table cells in CSS. One is most suitable for so-called separated borders around individual cells, the other is suitable for borders that are continuous from one end of the table to the other.

... and later, for collapse setting:

In the collapsing border model, it is possible to specify borders that surround all or part of a cell, row, row group, column, and column group.

    downloadJsonFile(data, filename: string){
        // Creating a blob object from non-blob data using the Blob constructor
        const blob = new Blob([JSON.stringify(data)], { type: 'application/json' });
        const url = URL.createObjectURL(blob);
        // Create a new anchor element
        const a = document.createElement('a');
        a.href = url;
        a.download = filename || 'download';
        a.click();
        a.remove();
      }

You can easily auto download file with using Blob and transfer it in first param downloadJsonFile. filename is name of file you wanna set.

As I wrote in the edits of the op, to edit existing excel documents you must use the xlutils module (Thanks Oliver)

Here is the proper way to do it:

#xlrd, xlutils and xlwt modules need to be installed.  
#Can be done via pip install <module>
from xlrd import open_workbook
from xlutils.copy import copy

rb = open_workbook("names.xls")
wb = copy(rb)

s = wb.get_sheet(0)
s.write(0,0,'A1')
wb.save('names.xls')

This replaces the contents of the cell located at a1 in the first sheet of "names.xls" with the text "a1", and then saves the document.

I tested 2 set based randomization methods against RAND() by generating 100,000,000 rows with each. To level the field the output is a float between 0-1 to mimic RAND(). Most of the code is testing infrastructure so I summarize the algorithms here:

-- Try #1 used
(CAST(CRYPT_GEN_RANDOM(8) AS BIGINT)%500000000000000000+500000000000000000.0)/1000000000000000000 AS Val
-- Try #2 used
RAND(Checksum(NewId()))
-- and to have a baseline to compare output with I used
RAND() -- this required executing 100000000 separate insert statements

Using CRYPT_GEN_RANDOM was clearly the most random since there is only a .000000001% chance of seeing even 1 duplicate when plucking 10^8 numbers FROM a set of 10^18 numbers. IOW we should not have seen any duplicates and this had none! This set took 44 seconds to generate on my laptop.

  FROM X
 GROUP BY x.Cnt;

RAND() alone is useless for set-based generation so generating the baseline for comparing randomness took over 6 hours and had to be restarted several times to finally get the right number of output rows. It also seems that the randomness leaves a lot to be desired although it's better than using checksum(newid()) to reseed each row.

Cnt  Pct
---- ----
1    99.768020
2    00.115840
3    00.000100  -- at least there were comparitively few values returned 3 times

Because of the restarts, execution time could not be captured.

IF OBJECT_ID('tempdb..#T2') IS NOT NULL DROP TABLE #T2;
GO
CREATE TABLE #T2 (Val FLOAT);
GO
SET NOCOUNT ON;
GO
INSERT INTO #T2(Val) VALUES(RAND());
GO 100000000

WITH x AS (
    SELECT Val,COUNT(*) Cnt
     FROM #T2
    GROUP BY Val

SELECT x.Cnt,COUNT(*)*1.0/(SELECT COUNT(*)/100 FROM #T2) Pct
  FROM X
 GROUP BY x.Cnt;

You can give the background image in css :

#canvas { background:url(example.jpg) }

it will show you canvas back ground image

Other answers suggest how to get a floating-point value. While this wlil be close to what you want, it won't be exact:

>>> 0.4/100.
0.0040000000000000001

If you actually want a decimal value, do this:

>>> import decimal
>>> decimal.Decimal('4') / decimal.Decimal('100')
Decimal("0.04")

That will give you an object that properly knows that 4 / 100 in base 10 is "0.04". Floating-point numbers are actually in base 2, i.e. binary, not decimal.

I think this link will be enough for you. I found it when I was searching for the way to execute oracle procedures.

Short Description:

--cursor variable declaration 
variable Out_Ref_Cursor refcursor;
--execute procedure 
execute get_employees_name(IN_Variable,:Out_Ref_Cursor);
--display result referenced by ref cursor.
print Out_Ref_Cursor;

If you'd decide for a solution acting "in place" you could take a look at this one:

>>> d = [ { 'a':'1' , 'b':'2' , 'c':'3' }, { 'd':'4' , 'e':'5' , 'f':'6' } ]
>>> [dt.update({k: int(v)}) for dt in d for k, v in dt.iteritems()]
[None, None, None, None, None, None]
>>> d
[{'a': 1, 'c': 3, 'b': 2}, {'e': 5, 'd': 4, 'f': 6}]

Btw, key order is not preserved because that's the way standard dictionaries work, ie without the concept of order.

SQL Developer seems to only output the DBMS_OUTPUT text when you have explicitly turned on the DBMS_OUTPUT window pane.

Go to (Menu) VIEW -> Dbms_output to invoke the pane.

Click on the Green Plus sign to enable output for your connection and then run the code.

EDIT: Don't forget to set the buffer size according to the amount of output you are expecting.

in case of a similar issue when I'm creating dockerfile I faced the same scenario:- I used below changed in mysql_connect function as:-

if($CONN = @mysqli_connect($DBHOST, $DBUSER, $DBPASS)){ //mysql_query("SET CHARACTER SET 'gbk'", $CONN);

In flutter version 1.14.6, Dart version 28.

Below is what worked for me, You simply just need to bundle everything you want to happen after the build method into a separate method or function.

@override
void initState() {
super.initState();
print('hello girl');

WidgetsBinding.instance
    .addPostFrameCallback((_) => afterLayoutWidgetBuild());

}

For me

Adding this line

<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script>

Before this line.

<script id="microloader" type="text/javascript" src=".sencha/app/microloader/development.js"></script>

worked

Binding to the button would not resolve for submissions outside of pressing the button e.g. pressing enter

Within your onDropDownChange handler, just make a jQuery AJAX call, passing in any data you need to pass up to your URL. You can handle successful and failure calls with the success and error options. In the success option, use the data contained in the data argument to do whatever rendering you need to do. Remember these are asynchronous by default!

function onDropDownChange(e) {
    var url = '/Home/Index/' + e.value;
    $.ajax({
      url: url,
      data: {}, //parameters go here in object literal form
      type: 'GET',
      datatype: 'json',
      success: function(data) { alert('got here with data'); },
      error: function() { alert('something bad happened'); }
    });
}

jQuery's AJAX documentation is here.

My two cents with example length of 30 :

  var truncatedInput = string.IsNullOrEmpty(input) ? 
      string.Empty : 
      input.Substring(0, Math.Min(input.Length, 30));

When you open Eclipse you should click File ? New ? Dynamic Web Project, and make sure you checked Generate web.xml, as described above.

If you have already created the project, you should go to the WebContent/WEB-INF folder, open web.xml, and put the following lines:

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">

As of Python 3.2 2.7, there is now argparse for processing command line arguments.

pdfrw will let you read in pages from an existing PDF and draw them to a reportlab canvas (similar to drawing an image). There are examples for this in the pdfrw examples/rl1 subdirectory on github. Disclaimer: I am the pdfrw author.

If you want to do something to each row in a DataFrame object, use map. This will allow you to perform further calculations on each row. It's the equivalent of looping across the entire dataset from 0 to len(dataset)-1.

Note that this will return a PipelinedRDD, not a DataFrame.

You can just append

track by version.id

to your ng-options.

To load your data in WebView. Call loadData() method of WebView

webView.loadData(yourData, "text/html; charset=utf-8", "UTF-8");

You can check this example

In HTML, the selected option is represented by the presence of the selected attribute on the <option> element like so:

<option ... selected>...</option>

Or if you're HTML/XHTML strict:

<option ... selected="selected">...</option>

Thus, you just have to let JSP/EL print it conditionally. Provided that you've prepared the selected department as follows:

request.setAttribute("selectedDept", selectedDept);

then this should do:

<select name="department">
    <c:forEach var="item" items="${dept}">
        <option value="${item.key}" ${item.key == selectedDept ? 'selected="selected"' : ''}>${item.value}</option>
    </c:forEach>
</select>

Try

: $(yourcommand)

: is short for "do nothing".

$() is just your command.

Try this:

if(myString != "-1")

The opperand is != and not =!

You can also use Equals

if(!myString.Equals("-1"))

Note the ! before myString

I can't pass up this opportunity to plug Josh Bloch's book Effective Java (2nd Edition). Chapter 11 is an indispensible resource on Java serialization.

Per Josh, the automatically-generated UID is generated based on a class name, implemented interfaces, and all public and protected members. Changing any of these in any way will change the serialVersionUID. So you don't need to mess with them only if you are certain that no more than one version of the class will ever be serialized (either across processes or retrieved from storage at a later time).

If you ignore them for now, and find later that you need to change the class in some way but maintain compatibility w/ old version of the class, you can use the JDK tool serialver to generate the serialVersionUID on the old class, and explicitly set that on the new class. (Depending on your changes you may need to also implement custom serialization by adding writeObject and readObject methods - see Serializable javadoc or aforementioned chapter 11.)

Probably the exact details of em.flush() are implementation-dependent. In general anyway, JPA providers like Hibernate can cache the SQL instructions they are supposed to send to the database, often until you actually commit the transaction. For example, you call em.persist(), Hibernate remembers it has to make a database INSERT, but does not actually execute the instruction until you commit the transaction. Afaik, this is mainly done for performance reasons.

In some cases anyway you want the SQL instructions to be executed immediately; generally when you need the result of some side effects, like an autogenerated key, or a database trigger.

What em.flush() does is to empty the internal SQL instructions cache, and execute it immediately to the database.

Bottom line: no harm is done, only you could have a (minor) performance hit since you are overriding the JPA provider decisions as regards the best timing to send SQL instructions to the database.

They are the same, Bool is just System.Boolean shortened. Use Boolean when you are with a VB.net programmer, since it works with both C# and Vb

Another alternative (15. gets typed to [timespan] automatically):

ls -file | where { (get-date) - $_.creationtime -gt 15. } | Remove-Item -Verbose

As mentioned in the Top answer, since java 8 it is possible to do:

Date dt = new Date();
LocalDateTime.from(dt.toInstant()).plusDays(1);

but this can sometimes lead to an DateTimeException like this:

java.time.DateTimeException: Unable to obtain LocalDateTime from TemporalAccessor: 2014-11-29T03:20:10.800Z of type java.time.Instant

It is possible to avoid this Exception by simply passing the time zone:

LocalDateTime.from(dt.toInstant().atZone(ZoneId.of("UTC"))).plusDays(1);

You can do this using Input.setSelectionRange, part of the Range API for interacting with text selections and the text cursor:

var searchInput = $('#Search');

// Multiply by 2 to ensure the cursor always ends up at the end;
// Opera sometimes sees a carriage return as 2 characters.
var strLength = searchInput.val().length * 2;

searchInput.focus();
searchInput[0].setSelectionRange(strLength, strLength);

Demo: Fiddle

First examine if you really need a global variable instead using it blatantly without consideration to your software architecture.

Let's assuming it passes the test. Depending on usage, Globals can be hard to debug with race conditions and many other "bad things", it's best to approach them from an angle where you're prepared to handle such bad things. So,

1. Wrap all such Global variables into a single static class (for manageability).
2. Have Properties instead of fields(='variables'). This way you have some mechanisms to address any issues with concurrent writes to Globals in the future.

The basic outline for such a class would be:

public class Globals
{
    private static bool _expired;
    public static bool Expired 
    {
        get
        {
            // Reads are usually simple
            return _expired;
        }
        set
        {
            // You can add logic here for race conditions,
            // or other measurements
            _expired = value;
        }
    }
    // Perhaps extend this to have Read-Modify-Write static methods
    // for data integrity during concurrency? Situational.
}

Usage from other classes (within same namespace)

// Read
bool areWeAlive = Globals.Expired;

// Write
// past deadline
Globals.Expired = true;

For me, the problem was trying to pass a filename in a url, with a dot. For example

"http://localhost:8080/something/asdf.jpg" //causes error because of '.jpg'

It could be solved by not passing the .jpg extension, or sending it all in a request body.

If you install TortoiseSVN you can use SVN under windows. It also gives you the SVN binaries. You needn't do the checkout from the command-line though as it integrates into Windows Explorer for you.

I think this will be much simpler for beginners in JavaScript

    //The function checks if the password and confirm password match
    // Then disables the submit button for mismatch but enables if they match
            function checkPass()
            {
                //Store the password field objects into variables ...
                var pass1 = document.getElementById("register-password");
                var pass2 = document.getElementById("confirm-password");
                //Store the Confimation Message Object ...
                var message = document.getElementById('confirmMessage');
                //Set the colors we will be using ...
                var goodColor = "#66cc66";
                var badColor = "#ff6666";
                //Compare the values in the password field 
                //and the confirmation field
                if(pass1.value == pass2.value){
                    //The passwords match. 
                    //Set the color to the good color and inform
                    //the user that they have entered the correct password 
                    pass2.style.backgroundColor = goodColor;
                    message.style.color = goodColor;
                    message.innerHTML = "Passwords Match!"
 //Enables the submit button when there's no mismatch                   
                    var tabPom = document.getElementById("btnSignUp");
                    $(tabPom ).prop('disabled', false);
                }else{
                    //The passwords do not match.
                    //Set the color to the bad color and
                    //notify the user.
                    pass2.style.backgroundColor = badColor;
                    message.style.color = badColor;
                    message.innerHTML = "Passwords Do Not Match!"
 //Disables the submit button when there's mismatch       
                    var tabPom = document.getElementById("btnSignUp");
                    $(tabPom ).prop('disabled', true);
                }
            } 

If you want to have the ListView in an AppCompatActivity instead of ListActivity, you can do the following (Modifying @Shardul's answer):

public class ListViewDemoActivity extends AppCompatActivity {
    //LIST OF ARRAY STRINGS WHICH WILL SERVE AS LIST ITEMS
    ArrayList<String> listItems=new ArrayList<String>();

    //DEFINING A STRING ADAPTER WHICH WILL HANDLE THE DATA OF THE LISTVIEW
    ArrayAdapter<String> adapter;

    //RECORDING HOW MANY TIMES THE BUTTON HAS BEEN CLICKED
    int clickCounter=0;
    private ListView mListView;

    @Override
    public void onCreate(Bundle icicle) {
        super.onCreate(icicle);
        setContentView(R.layout.activity_list_view_demo);

        if (mListView == null) {
            mListView = (ListView) findViewById(R.id.listDemo);
        }

        adapter=new ArrayAdapter<String>(this,
                android.R.layout.simple_list_item_1,
                listItems);
        setListAdapter(adapter);
    }

    //METHOD WHICH WILL HANDLE DYNAMIC INSERTION
    public void addItems(View v) {
        listItems.add("Clicked : "+clickCounter++);
        adapter.notifyDataSetChanged();
    }

    protected ListView getListView() {
        if (mListView == null) {
            mListView = (ListView) findViewById(R.id.listDemo);
        }
        return mListView;
    }

    protected void setListAdapter(ListAdapter adapter) {
        getListView().setAdapter(adapter);
    }

    protected ListAdapter getListAdapter() {
        ListAdapter adapter = getListView().getAdapter();
        if (adapter instanceof HeaderViewListAdapter) {
            return ((HeaderViewListAdapter)adapter).getWrappedAdapter();
        } else {
            return adapter;
        }
    }
}

And in you layout instead of using android:id="@android:id/list" you can use android:id="@+id/listDemo"

So now you can have a ListView inside a normal AppCompatActivity.

Request-scoped beans can be autowired with the request object.

private @Autowired HttpServletRequest request;

string::c.str() returns a string of type const char * as seen here

A quick fix: try casting printfunc(num,addr,(char *)data.str().c_str());

While the above may work, it is undefined behaviour, and unsafe.

Here's a nicer solution using templates:

char * my_argument = const_cast<char*> ( ...c_str() );

I have written my own that you can use. This one works has sqlite, is thread safe and is in C++ for UNIX.

You should be able to pick it apart and use the C compatible code.

Sometimes a BEFORE trigger can be replaced with an AFTER one, but this doesn't appear to be the case in your situation, for you clearly need to provide a value before the insert takes place. So, for that purpose, the closest functionality would seem to be the INSTEAD OF trigger one, as @marc_s has suggested in his comment.

Note, however, that, as the names of these two trigger types suggest, there's a fundamental difference between a BEFORE trigger and an INSTEAD OF one. While in both cases the trigger is executed at the time when the action determined by the statement that's invoked the trigger hasn't taken place, in case of the INSTEAD OF trigger the action is never supposed to take place at all. The real action that you need to be done must be done by the trigger itself. This is very unlike the BEFORE trigger functionality, where the statement is always due to execute, unless, of course, you explicitly roll it back.

But there's one other issue to address actually. As your Oracle script reveals, the trigger you need to convert uses another feature unsupported by SQL Server, which is that of FOR EACH ROW. There are no per-row triggers in SQL Server either, only per-statement ones. That means that you need to always keep in mind that the inserted data are a row set, not just a single row. That adds more complexity, although that'll probably conclude the list of things you need to account for.

So, it's really two things to solve then:

• replace the BEFORE functionality;

• replace the FOR EACH ROW functionality.

My attempt at solving these is below:

CREATE TRIGGER sub_trg
ON sub1
INSTEAD OF INSERT
AS
BEGIN
  DECLARE @new_super TABLE (
    super_id int
  );
  INSERT INTO super (subtype_discriminator)
  OUTPUT INSERTED.super_id INTO @new_super (super_id)
  SELECT 'SUB1' FROM INSERTED;

  INSERT INTO sub (super_id)
  SELECT super_id FROM @new_super;
END;

This is how the above works:

1. The same number of rows as being inserted into sub1 is first added to super. The generated super_id values are stored in a temporary storage (a table variable called @new_super).

2. The newly inserted super_ids are now inserted into sub1.

Nothing too difficult really, but the above will only work if you have no other columns in sub1 than those you've specified in your question. If there are other columns, the above trigger will need to be a bit more complex.

The problem is to assign the new super_ids to every inserted row individually. One way to implement the mapping could be like below:

CREATE TRIGGER sub_trg
ON sub1
INSTEAD OF INSERT
AS
BEGIN
  DECLARE @new_super TABLE (
    rownum   int IDENTITY (1, 1),
    super_id int
  );
  INSERT INTO super (subtype_discriminator)
  OUTPUT INSERTED.super_id INTO @new_super (super_id)
  SELECT 'SUB1' FROM INSERTED;

  WITH enumerated AS (
    SELECT *, ROW_NUMBER() OVER (ORDER BY (SELECT 1)) AS rownum
    FROM inserted
  )
  INSERT INTO sub1 (super_id, other columns)
  SELECT n.super_id, i.other columns
  FROM enumerated AS i
  INNER JOIN @new_super AS n
  ON i.rownum = n.rownum;
END;

As you can see, an IDENTIY(1,1) column is added to @new_user, so the temporarily inserted super_id values will additionally be enumerated starting from 1. To provide the mapping between the new super_ids and the new data rows, the ROW_NUMBER function is used to enumerate the INSERTED rows as well. As a result, every row in the INSERTED set can now be linked to a single super_id and thus complemented to a full data row to be inserted into sub1.

Note that the order in which the new super_ids are inserted may not match the order in which they are assigned. I considered that a no-issue. All the new super rows generated are identical save for the IDs. So, all you need here is just to take one new super_id per new sub1 row.

If, however, the logic of inserting into super is more complex and for some reason you need to remember precisely which new super_id has been generated for which new sub row, you'll probably want to consider the mapping method discussed in this Stack Overflow question:

• Using merge..output to get mapping between source.id and target.id

The law of the big three is as specified above.

An easy example, in plain English, of the kind of problem it solves:

Non default destructor

You allocated memory in your constructor and so you need to write a destructor to delete it. Otherwise you will cause a memory leak.

You might think that this is job done.

The problem will be, if a copy is made of your object, then the copy will point to the same memory as the original object.

Once, one of these deletes the memory in its destructor, the other will have a pointer to invalid memory (this is called a dangling pointer) when it tries to use it things are going to get hairy.

Therefore, you write a copy constructor so that it allocates new objects their own pieces of memory to destroy.

Assignment operator and copy constructor

You allocated memory in your constructor to a member pointer of your class. When you copy an object of this class the default assignment operator and copy constructor will copy the value of this member pointer to the new object.

This means that the new object and the old object will be pointing at the same piece of memory so when you change it in one object it will be changed for the other objerct too. If one object deletes this memory the other will carry on trying to use it - eek.

To resolve this you write your own version of the copy constructor and assignment operator. Your versions allocate separate memory to the new objects and copy across the values that the first pointer is pointing to rather than its address.

If you want to download an image from https:

$output_filename = 'output.png';
$host = "https://.../source.png"; // <-- Source image url (FIX THIS)
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $host);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_AUTOREFERER, false);
curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_1);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0); // <-- don't forget this
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0); // <-- and this
$result = curl_exec($ch);
curl_close($ch);
$fp = fopen($output_filename, 'wb');
fwrite($fp, $result);
fclose($fp);

Firstly, you need to be aware that UTC isn't a format, it's a time zone, effectively. So "converting from ISO8601 to UTC" doesn't really make sense as a concept.

However, here's a sample program using Joda Time which parses the text into a DateTime and then formats it. I've guessed at a format you may want to use - you haven't really provided enough information about what you're trying to do to say more than that. You may also want to consider time zones... do you want to display the local time at the specified instant? If so, you'll need to work out the user's time zone and convert appropriately.

import org.joda.time.*;
import org.joda.time.format.*;

public class Test {
    public static void main(String[] args) {
        String text = "2011-03-10T11:54:30.207Z";
        DateTimeFormatter parser = ISODateTimeFormat.dateTime();
        DateTime dt = parser.parseDateTime(text);

        DateTimeFormatter formatter = DateTimeFormat.mediumDateTime();
        System.out.println(formatter.print(dt));
    }
}

Get a reference to your input box however you like (eg document.getElementById('mytextbox')) and set its readonly property to true:

myInputBox.readonly = true;

Alternatively you can simply add this property inline (no JavaScript needed):

<input type="text" value="from db" readonly="readonly" />

Let's assume that you have a List<String> strings that you want the first item from.

There are several ways to do that:

Java (pre-8):

String firstElement = null;
if (!strings.isEmpty() && strings.size() > 0) {
    firstElement = strings.get(0);
}

Java 8:

Optional<String> firstElement = strings.stream().findFirst();

Guava

String firstElement = Iterables.getFirst(strings, null);

Apache commons (4+)

String firstElement = (String) IteratorUtils.get(strings, 0);

Apache commons (before 4)

String firstElement = (String) CollectionUtils.get(strings, 0);

Followed by or encapsulated within the appropriate checks or try-catch blocks.

Kotlin:

In Kotlin both Arrays and most of the Collections (eg: List) have a first method call. So your code would look something like this

for a List:

val stringsList: List<String?> = listOf("a", "b", null)
val first: String? = stringsList.first()

for an Array:

val stringArray: Array<String?> = arrayOf("a", "b", null)
val first: String? = stringArray.first()

Followed by or encapsulated within the appropriate checks or try-catch blocks.

Kotlin also includes safer ways to do that for kotlin.collections, for example firstOrNull or getOrElse, or getOrDefault when using JRE8

Another option is use this script that execute "aws configservice list-discovered-resources --resource-type" for every resource

If it's an object method, you need to pass the object to CallObjectMethod:

jobject result = env->CallObjectMethod(obj, messageMe, jstr);

What you were doing was the equivalent of jstr.messageMe().

Since your is a void method, you should call:

env->CallVoidMethod(obj, messageMe, jstr);

If you want to return a result, you need to change your JNI signature (the ()V means a method of void return type) and also the return type in your Java code.

Better you copy and move them to your own resources. Some resources might not be available on previous Android versions. Here is a link with all drawables available on each Android version thanks to @fiXedd

df['col'] = 'str' + df['col'].astype(str)

Pure javascript would be like this

var children = document.getElementById('test').children;

If you are using jQuery it would be like this

$("#test").children()

In my opinion, these were used as a way to quickly find include files when developing. Really these have been made obsolete with conventions and framework designs.

simple is the best and works in every version.

if a>10: 
    value="b"
else: 
    value="c"

I had this similar error when using wget ..., and after much unfruitful searching in the Internet, I discovered that it was happening when hostnames were being resolved to IPv6 addresses. I discovered this by comparing the outputs of wget ... in two machines, one was resolving to IPv4 and it worked there, the other was resolving to IPv6 and it failed there.

So the solution in my case was to run networksetup -setv6off Wi-Fi on macOS High Sierra 10.13.6. (I discovered this command in this page).

Hope this helps you.

Non-Americans take note! If you use Excel with "." as 1000 separator, you need to replace the "," with a "." in the formula, such as:

[>=1000]€ #.##0." K";[<=-1000]-€ #.##0." K";0

The code above will display € 62.123 as "€ 62 K".

I have catched the same exception and found a InnerException: SocketException. in the svclog trace.

After looking in the windows event log I saw an error coming from the System.ServiceModel.Activation.TcpWorkerProcess class.

Are you hosting your wcf service in IIS with netTcpBinding and port sharing?

It seems there is a bug in IIS port sharing feature, check the fix:

My solution is to host your WCF service in a Windows Service.
