I installed miniconda and found all the installed packages in /miniconda3/pkgs

As of the writing of my current comment, I don't know about the PHP threads. I came to look for the answer here myself, but one workaround is that the PHP program that receives the request from the web server delegates the whole answer formulation to a console application that stores its output, the answer to the request, to a binary file and the PHP program that launched the console application returns that binary file byte-by-byte as the answer to the received request. The console application can be written in any programming language that runs on the server, including those that have proper threading support, including C++ programs that use OpenMP.

One unreliable, dirty, trick is to use PHP for executing a console application, "uname",

uname -a

and print the output of that console command to the HTML output to find out the exact version of the server software. Then install the exact same version of the software to a VirtualBox instance, compile/assemble whatever fully self-contained, preferably static, binaries that one wants and then upload those to the server. From that point onwards the PHP application can use those binaries in the role of the console application that has proper multi-threading. It's a dirty, unreliable, workaround to a situation, when the server administrator has not installed all needed programming language implementations to the server. The thing to watch out for is that at every request that the PHP application receives the console application(s) terminates/exit/get_killed.

As to what the hosting service administrators think of such server usage patterns, I guess it boils down to culture. In Northern Europe the service provider HAS TO DELIVER WHAT WAS ADVERTISED and if execution of console commands was allowed and uploading of non-malware files was allowed and the service provider has a right to kill any server process after a few minutes or even after 30 seconds, then the hosting service administrators lack any arguments for forming a proper complaint. In United States and Western Europe the situation/culture is very different and I believe that there's a great chance that in U.S. and/or Western Europe the hosting service provider will refuse to serve hosting service clients that use the above described trick. That's just my guess, given my personal experience with U.S. hosting services and given what I have heard from others about Western European hosting services. As of the writing of my current comment(2018_09_01) I do not know anything about the cultural norms of the Southern-European hosting service providers, Southern-European network administrators.

I have dealt with this at talkstats.com in posts 94, 101 & 103 found in the thread: Share Your Code. As others have said Rstudio may be a better way to go. I store these functions in my .Rprofile and actually use them a but to automatically block out lines of code quickly.

Not quite as nice as you were hoping for but may be an approach.

I. Plain XSLT 1.0 solution:

This transformation:

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output omit-xml-declaration="yes" indent="yes"/>

 <xsl:template match="text()" name="split">
  <xsl:param name="pText" select="."/>
  <xsl:if test="string-length($pText)">
   <xsl:if test="not($pText=.)">
    <br />
   </xsl:if>
   <xsl:value-of select=
    "substring-before(concat($pText,';'),';')"/>
   <xsl:call-template name="split">
    <xsl:with-param name="pText" select=
     "substring-after($pText, ';')"/>
   </xsl:call-template>
  </xsl:if>
 </xsl:template>
</xsl:stylesheet>

when applied on this XML document:

<t>123 Elm Street;PO Box 222;c/o James Jones</t>

produces the wanted, corrected result:

123 Elm Street<br />PO Box 222<br />c/o James Jones

II. FXSL 1 (for XSLT 1.0):

Here we just use the FXSL template str-map (and do not have to write recursive template for the 999th time):

<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:f="http://fxsl.sf.net/"
xmlns:testmap="testmap"
exclude-result-prefixes="xsl f testmap"
>
   <xsl:import href="str-dvc-map.xsl"/>

   <testmap:testmap/>

   <xsl:output omit-xml-declaration="yes" indent="yes"/>

   <xsl:template match="/">
     <xsl:variable name="vTestMap" select="document('')/*/testmap:*[1]"/>
     <xsl:call-template name="str-map">
       <xsl:with-param name="pFun" select="$vTestMap"/>
       <xsl:with-param name="pStr" select=
       "'123 Elm Street;PO Box 222;c/o James Jones'"/>
     </xsl:call-template>
   </xsl:template>

    <xsl:template name="replace" mode="f:FXSL"
         match="*[namespace-uri() = 'testmap']">
      <xsl:param name="arg1"/>

      <xsl:choose>
       <xsl:when test="not($arg1=';')">
        <xsl:value-of select="$arg1"/>
       </xsl:when>
       <xsl:otherwise><br /></xsl:otherwise>
      </xsl:choose>
    </xsl:template>
</xsl:stylesheet>

when this transformation is applied on any XML document (not used), the same, wanted correct result is produced:

123 Elm Street<br/>PO Box 222<br/>c/o James Jones

III. Using XSLT 2.0

<xsl:stylesheet version="2.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output omit-xml-declaration="yes" indent="yes"/>

 <xsl:template match="text()">
  <xsl:for-each select="tokenize(.,';')">
   <xsl:sequence select="."/>
   <xsl:if test="not(position() eq last())"><br /></xsl:if>
  </xsl:for-each>
 </xsl:template>
</xsl:stylesheet>

when this transformation is applied on this XML document:

<t>123 Elm Street;PO Box 222;c/o James Jones</t>

the wanted, correct result is produced:

123 Elm Street<br />PO Box 222<br />c/o James Jones

The best way is to create a variable of type Worksheet, assign the worksheet and use it every time the VBA would implicitly use the ActiveSheet.

This will help you avoid bugs that will eventually show up when your program grows in size.

For example something like Range("A1:C10").Sort Key1:=Range("A2") is good when the macro works only on one sheet. But you will eventually expand your macro to work with several sheets, find out that this doesn't work, adjust it to ShTest1.Range("A1:C10").Sort Key1:=Range("A2")... and find out that it still doesn't work.

Here is the correct way:

Dim ShTest1 As Worksheet
Set ShTest1 = Sheets("Test1")
ShTest1.Range("A1:C10").Sort Key1:=ShTest1.Range("A2")

I had same problem. It was resolved by running same code in Administrator Console.

Note that Git 1.9/2.0 (Q1 2014) has removed that limitation.
See commit 82fba2b, from Nguy?n Thái Ng?c Duy (pclouds):

Now that git supports data transfer from or to a shallow clone, these limitations are not true anymore.

The documentation now reads:

--depth <depth>::

Create a 'shallow' clone with a history truncated to the specified number of revisions.

That stems from commits like 0d7d285, f2c681c, and c29a7b8 which support clone, send-pack /receive-pack with/from shallow clones.
smart-http now supports shallow fetch/clone too.

All the details are in "shallow.c: the 8 steps to select new commits for .git/shallow".

Update June 2015: Git 2.5 will even allow for fetching a single commit!
(Ultimate shallow case)

Update January 2016: Git 2.8 (Mach 2016) now documents officially the practice of getting a minimal history.
See commit 99487cf, commit 9cfde9e (30 Dec 2015), commit 9cfde9e (30 Dec 2015), commit bac5874 (29 Dec 2015), and commit 1de2e44 (28 Dec 2015) by Stephen P. Smith (``).
^{(Merged by Junio C Hamano -- gitster -- in commit 7e3e80a, 20 Jan 2016)}

This is "Documentation/user-manual.txt"

A <<def_shallow_clone,shallow clone>> is created by specifying the git-clone --depth switch.
The depth can later be changed with the git-fetch --depth switch, or full history restored with --unshallow.

Merging inside a <<def_shallow_clone,shallow clone>> will work as long as a merge base is in the recent history.
Otherwise, it will be like merging unrelated histories and may have to result in huge conflicts.
This limitation may make such a repository unsuitable to be used in merge based workflows.

Update 2020:

• git 2.11.1 introduced option git fetch --shallow-exclude= to prevent fetching all history
• git 2.11.1 introduced option git fetch --shallow-since= to prevent fetching old commits.

For more on the shallow clone update process, see "How to update a git shallow clone?".

As commented by Richard Michael:

to backfill history: git pull --unshallow

And Olle Härstedt adds in the comments:

To backfill part of the history: git fetch --depth=100.

Do I need to setup specific URLconf patters for uploaded media?

Yes. For development, it's as easy as adding this to your URLconf:

if settings.DEBUG:
    urlpatterns += patterns('django.views.static',
        (r'media/(?P<path>.*)', 'serve', {'document_root': settings.MEDIA_ROOT}),
    )

However, for production, you'll want to serve the media using Apache, lighttpd, nginx, or your preferred web server.

I just replicate the 2 attributes of the btn-navbar (data-toggle="collapse" data-target=".nav-collapse.in") on each link like this:

<div class="nav-collapse">
  <ul class="nav" >
    <li class="active"><a href="#home" data-toggle="collapse" data-target=".nav-collapse.in">Home</a></li>
    <li><a href="#about" data-toggle="collapse" data-target=".nav-collapse.in">About</a></li>
    <li><a href="#portfolio" data-toggle="collapse" data-target=".nav-collapse.in">Portfolio</a></li>
    <li><a href="#services" data-toggle="collapse" data-target=".nav-collapse.in">Services</a></li>
    <li><a href="#contact" data-toggle="collapse" data-target=".nav-collapse.in">Contact</a></li>
  </ul>
</div>

In the Bootstrap 4 Navbar, in has changed to show so the syntax would be:

data-toggle="collapse" data-target=".navbar-collapse.show"

It's not sure what you mean with 'the program', but if you want to limit your application to one instance then you can use a Mutex to make sure that your application isn't already running.

[STAThread]
static void Main()
{
    Mutex mutex = new System.Threading.Mutex(false, "MyUniqueMutexName");
    try
    {
        if (mutex.WaitOne(0, false))
        {
            // Run the application
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            Application.Run(new MainForm());
        }
        else
        {
            MessageBox.Show("An instance of the application is already running.");
        }
    }
    finally
    {
        if (mutex != null)
        {
            mutex.Close();
            mutex = null;
        }
    }
}

I'll assume that Time and Product are columns in a DataFrame, df is an instance of DataFrame, and that other variables are scalar values:

For now, you'll have to reference the DataFrame instance:

k1 = df.loc[(df.Product == p_id) & (df.Time >= start_time) & (df.Time < end_time), ['Time', 'Product']]

The parentheses are also necessary, because of the precedence of the & operator vs. the comparison operators. The & operator is actually an overloaded bitwise operator which has the same precedence as arithmetic operators which in turn have a higher precedence than comparison operators.

In pandas 0.13 a new experimental DataFrame.query() method will be available. It's extremely similar to subset modulo the select argument:

With query() you'd do it like this:

df[['Time', 'Product']].query('Product == p_id and Month < mn and Year == yr')

Here's a simple example:

In [9]: df = DataFrame({'gender': np.random.choice(['m', 'f'], size=10), 'price': poisson(100, size=10)})

In [10]: df
Out[10]:
  gender  price
0      m     89
1      f    123
2      f    100
3      m    104
4      m     98
5      m    103
6      f    100
7      f    109
8      f     95
9      m     87

In [11]: df.query('gender == "m" and price < 100')
Out[11]:
  gender  price
0      m     89
4      m     98
9      m     87

The final query that you're interested will even be able to take advantage of chained comparisons, like this:

k1 = df[['Time', 'Product']].query('Product == p_id and start_time <= Time < end_time')

You can also use UUID class from java.util package, which returns random uuid of 32bit characters String.

java.util.UUID.randomUUID().toString()

http://java.sun.com/j2se/1.5.0/docs/api/java/util/UUID.html

Two options, either reference the new jars in your classpath or unpack all classes in the enclosing jars and re-jar the whole lot! As far as I know packaging jars within jars is not recommeneded and you'll forever have the class not found exception!

The project you downloaded is a class library. Which can't be started.

Add a new project which can be started (console app, win forms, what ever you want) and add a reference to the class library project to be able to "play with it".

And set this new project as "Startup project"

Just in case you are not sure the string starts with a word...

$input = ' Test me more ';
echo preg_replace('/(\s*)([^\s]*)(.*)/', '$2', $input); //Test

Update: a better idea, set the "AppendDataBoundItems" property to true, then declare the "Choose item" declaratively. The databinding operation will add to the statically declared item.

<asp:DropDownList ID="ddl" runat="server" AppendDataBoundItems="true">
    <asp:ListItem Value="0" Text="Please choose..."></asp:ListItem>
</asp:DropDownList>

I pass around a simple Hashtable object with a single result member to avoid the return craziness as I also want to output to the console. It acts through pass by reference.

function sample-loop($returnObj) {
  for($i = 0; $i -lt 10; $i++) {
    Write-Host "loop counter: $i"
    $returnObj.result++
  }
}

function main-sample() {
  $countObj = @{ result = 0 }
  sample-loop -returnObj $countObj
  Write-Host "_____________"
  Write-Host "Total = " ($countObj.result)
}

main-sample

You can see real example usage at my GitHub project unpackTunes.

ES6 WeakMaps

By using a simple pattern based in ES6 WeakMaps is possible to obtain private member variables, reachable from the prototype functions.

Note : The usage of WeakMaps guarantees safety against memory leaks, by letting the Garbage Collector identify and discard unused instances.

// Create a private scope using an Immediately _x000D_
// Invoked Function Expression..._x000D_
let Person = (function() {_x000D_
_x000D_
    // Create the WeakMap that will hold each  _x000D_
    // Instance collection's of private data_x000D_
    let privateData = new WeakMap();_x000D_
    _x000D_
    // Declare the Constructor :_x000D_
    function Person(name) {_x000D_
        // Insert the private data in the WeakMap,_x000D_
        // using 'this' as a unique acces Key_x000D_
        privateData.set(this, { name: name });_x000D_
    }_x000D_
    _x000D_
    // Declare a prototype method _x000D_
    Person.prototype.getName = function() {_x000D_
        // Because 'privateData' is in the same _x000D_
        // scope, it's contents can be retrieved..._x000D_
        // by using  again 'this' , as  the acces key _x000D_
        return privateData.get(this).name;_x000D_
    };_x000D_
_x000D_
    // return the Constructor_x000D_
    return Person;_x000D_
}());

A more detailed explanation of this pattern can be found here

Set the parent div as position:relative and the inner element to position:absolute; bottom:0

Kind of an anonymous lookup table rather than a long switch statement:

return (const char *[]) {
    "bananas & monkeys",
    "Round and orange", 
    "APPLE",
}[enumVal];

it should. Typically that's how you do multiple selectors. Otherwise it may not like you trying to assign the return values of three uploads to the same var.

I would suggest using .each or maybe push the returns to an array rather than assigning them to that value.

I was just looking for a solution to this problem, came to this page. I know its dated but the previous solutions where unsatisfying or didn't work for me. Here is my work around if interested.

filename = "your_file.R"
filepath = file.choose()  # browse and select your_file.R in the window
dir = substr(filepath, 1, nchar(filepath)-nchar(filename))
setwd(dir)

You want a multiple attribute selector

$("input[type='checkbox'][name='ProductCode']").each(function(){ ...

or

$("input:checkbox[name='ProductCode']").each(function(){ ...

It would be better to use a CSS class to identify those that you want to select however as a lot of the modern browsers implement the document.getElementsByClassName method which will be used to select elements and be much faster than selecting by the name attribute

It also happened to me

I use this code and it worked

require('events').EventEmitter.defaultMaxListeners = infinity;

Try it out. It may help

Style the label with CSS and use pointer events :

<label>
<select>
   <option value="0">Zero</option>
   <option value="1">One</option>
</select>
</label>

and the relative CSS is

label:after {
    content:'\25BC';
    display:inline-block;
    color:#000;
    background-color:#fff;
    margin-left:-17px;   /* remove the damn :after space */
    pointer-events:none; /* let the click pass trough */
}

I just used a down arrow here, but you can set a block with a background image. Here is a ugly fiddle sample: https://jsfiddle.net/1rofzz89/

There is an application for both Mac & Windows call Handbrake, i know this isn't command line stuff but for a quick open file - select output file format & rough output size whilst keeping most of the good stuff about the video then this is good, it's a just a graphical view of ffmpeg at its best ... It does support command line input for those die hard texters.. https://handbrake.fr/downloads.php

Via which interface? Using the REST interface, you just send a delete:

DELETE /ObjectName HTTP/1.1
Host: BucketName.s3.amazonaws.com
Date: date
Content-Length: length
Authorization: signatureValue

Via the SOAP interface:

<DeleteObject xmlns="http://doc.s3.amazonaws.com/2006-03-01">
  <Bucket>quotes</Bucket>
  <Key>Nelson</Key>
  <AWSAccessKeyId> 1D9FVRAYCP1VJEXAMPLE=</AWSAccessKeyId>
  <Timestamp>2006-03-01T12:00:00.183Z</Timestamp>
  <Signature>Iuyz3d3P0aTou39dzbqaEXAMPLE=</Signature>
</DeleteObject>

If you're using a Python library like boto, it should expose a "delete" feature, like delete_key().

Have a look at the sizemode property of the picturebox.

pictureBox1.SizeMode =PictureBoxSizeMode.StretchImage;

I recently had to figure this out for myself and ended up on a solution inspired by @Zahymaka 's answer, but solving the 2x looping of the array.

What you can do is create an array with all your keys, in the order they exist, and then loop through that.

        $keys=array_keys($items);
        foreach($keys as $index=>$key){
                    echo "position: $index".PHP_EOL."item: ".PHP_EOL;
                    var_dump($items[$key]);
                    ...
        }

PS: I know this is very late to the party, but since I found myself searching for this, maybe this could be helpful to someone else

One of your tables has the same column name's which brings a confusion in the query as to which columns of the tables are you referring to. Copy this code and run it.

SELECT 
    v.VendorName, i.InvoiceID, iL.InvoiceSequence, iL.InvoiceLineItemAmount
FROM Vendors AS v
JOIN Invoices AS i ON (v.VendorID = .VendorID)
JOIN InvoiceLineItems AS iL ON (i.InvoiceID = iL.InvoiceID)
WHERE  
    I.InvoiceID IN
        (SELECT iL.InvoiceSequence 
         FROM InvoiceLineItems
         WHERE iL.InvoiceSequence > 1)
ORDER BY 
    V.VendorName, i.InvoiceID, iL.InvoiceSequence, iL.InvoiceLineItemAmount

What you are describing is a change of state in the parent. You pass that to the child via a prop. As you suggested, you would watch that prop. When the child takes action, it notifies the parent via an emit, and the parent might then change the state again.

var Child = {_x000D_
  template: '<div>{{counter}}</div>',_x000D_
  props: ['canI'],_x000D_
  data: function () {_x000D_
    return {_x000D_
      counter: 0_x000D_
    };_x000D_
  },_x000D_
  watch: {_x000D_
    canI: function () {_x000D_
      if (this.canI) {_x000D_
        ++this.counter;_x000D_
        this.$emit('increment');_x000D_
      }_x000D_
    }_x000D_
  }_x000D_
}_x000D_
new Vue({_x000D_
  el: '#app',_x000D_
  components: {_x000D_
    'my-component': Child_x000D_
  },_x000D_
  data: {_x000D_
    childState: false_x000D_
  },_x000D_
  methods: {_x000D_
    permitChild: function () {_x000D_
      this.childState = true;_x000D_
    },_x000D_
    lockChild: function () {_x000D_
      this.childState = false;_x000D_
    }_x000D_
  }_x000D_
})

<script src="//cdnjs.cloudflare.com/ajax/libs/vue/2.2.1/vue.js"></script>_x000D_
<div id="app">_x000D_
<my-component :can-I="childState" v-on:increment="lockChild"></my-component>_x000D_
<button @click="permitChild">Go</button>_x000D_
</div>

If you truly want to pass events to a child, you can do that by creating a bus (which is just a Vue instance) and passing it to the child as a prop.

I thought I'd add another perspective here. The answer depends on whether the question is assuming weak scaling or strong scaling.

From Wikipedia:

Weak scaling: how the solution time varies with the number of processors for a fixed problem size per processor.

Strong scaling: how the solution time varies with the number of processors for a fixed total problem size.

If the question is assuming weak scaling then @Gonzalo's answer suffices. However if the question is assuming strong scaling, there's something more to add. In strong scaling you're assuming a fixed workload size so if you increase the number of threads, the size of the data that each thread needs to work on decreases. On modern CPUs memory accesses are expensive and would be preferable to maintain locality by keeping the data in caches. Therefore, the likely optimal number of threads can be found when the dataset of each thread fits in each core's cache (I'm not going into the details of discussing whether it's L1/L2/L3 cache(s) of the system).

This holds true even when the number of threads exceeds the number of cores. For example assume there's 8 arbitrary unit (or AU) of work in the program which will be executed on a 4 core machine.

Case 1: run with four threads where each thread needs to complete 2AU. Each thread takes 10s to complete (with a lot of cache misses). With four cores the total amount of time will be 10s (10s * 4 threads / 4 cores).

Case 2: run with eight threads where each thread needs to complete 1AU. Each thread takes only 2s (instead of 5s because of the reduced amount of cache misses). With four cores the total amount of time will be 4s (2s * 8 threads / 4 cores).

I've simplified the problem and ignored overheads mentioned in other answers (e.g., context switches) but hope you get the point that it might be beneficial to have more number of threads than the available number of cores, depending on the data size you're dealing with.

Yes, this is something that you should worry about. Check the length of your objects with nrow(). R can auto-replicate objects so that they're the same length if they differ, which means you might be performing operations on mismatched data.

In this case you have an obvious flaw in that your subtracting aggregated data from raw data. These will definitely be of different lengths. I suggest that you merge them as time series (using the dates), then locf(), then do your subtraction. Otherwise merge them by truncating the original dates to the same interval as the aggregated series. Just be very careful that you don't drop observations.

Lastly, as some general advice as you get started: look at the result of your computations to see if they make sense. You might even pull them into a spreadsheet and replicate the results.

To make it simple, you can think of it like that;

• If it encounters the break command in the for loop, the else part will not be called.
• If it does not encounter the break command in the for loop, the else part will be called.

In other words, if for loop iteration is not "broken" with break, the else part will be called.

Try this

index.html

<form action="form.php" method="post">
    Do you like stackoverflow?
    <input type="checkbox" name="like" value="Yes" />  
    <input type="submit" name="formSubmit" value="Submit" /> 
</form>

form.php

<html>
<head>
</head>
<body>

<?php
    if(isset($_POST['like']))
    {
        echo "<h1>You like Stackoverflow.<h1>";
    }
    else
    {
        echo "<h1>You don't like Stackoverflow.</h1>";
    }   
?>

</body>
</html>

Or this

<?php
    if(isset($_POST['like'])) && 
    $_POST['like'] == 'Yes') 
    {
        echo "You like Stackoverflow.";
    }
    else
    {
        echo "You don't like Stackoverflow.";
    }   
?>

You can do so from within vim and use its own windows or tabs.

One way to go is to utilize the built-in file explorer; activate it via :Explore, or :Texplore for a tabbed interface (which I find most comfortable).

:Texplore (and :Sexplore) will also guard you from accidentally exiting the current buffer (editor) on :q once you're inside the explorer.

To toggle between open tabs when using tab pages use gt or gT (next tab and previous tab, respectively).

See also Using tab pages on the vim wiki.

For me, the only working solution was to simply add this in file ~/.ssh/config:

Host *
  IdentityFile ~/.ssh/your_ssh_key
  IdentityFile ~/.ssh/your_ssh_key2
  IdentityFile ~/.ssh/your_ssh_key3
  AddKeysToAgent yes

your_ssh_key is without any extension. Don't use .pub.

To get a nice ncurses-like inputbox use the command dialog like this:

#!/bin/bash
if (dialog --title "Message" --yesno "Want to do something risky?" 6 25)
# message box will have the size 25x6 characters
then 
    echo "Let's do something risky"
    # do something risky
else 
    echo "Let's stay boring"
fi

The dialog package is installed by default at least with SUSE Linux. Looks like:

I think it depends on what problems you are facing.

1. shortest path on simple graph -> bfs
2. all possible results -> dfs
3. search on graph(treat tree, martix as a graph too) -> dfs ....

I had this problem, and turns out the problem was that I had used

new SimpleJdbcCall(jdbcTemplate)
    .withProcedureName("foo")

instead of

new SimpleJdbcCall(jdbcTemplate)
    .withFunctionName("foo")

It actually works now from bower.

bower install material-design-icons --save

It downloads 37.1 KBs. Then it extracts and installs. You will see a folder called material-design-icons in bower_components folder. The total size is around 299KBs

An application when installed on a device or on an emulator will install at:

/data/data/APP_PACKAGE_NAME

The APK itself is placed in the /data/app/ folder.

These paths, however, are in the System Partition and to access them, you will need to have root. This is for a device. On the emulator, you can see it in your logcat (DDMS) in the File Explorer tab

By the way, it only shows the package name that is defined in your Manifest.XML under the package="APP_PACKAGE_NAME" attribute. Any other packages you may have created in your project in Eclipse do not show up here.

You are not setting a classpath that includes your compiled class! java can't find any classes if you don't tell it where to look.

java -cp [compiler outpur dir] HelloWorld

Incidentally you do not need to set CLASSPATH the way you have done.

if you are not using model as per your question you can do like this

@Html.Hidden("hdnFlag" , new {id = "hdnFlag", value = "hdnFlag_value" })

else if you are using model (considering passing model has hdnFlag property), you can use this approch

@Html.HiddenFor(model => model.hdnFlag, new { value = Model.hdnFlag})

Simply put, you are doing this completely backward.

You should not be approaching this from what URLs you should be using. The URLs will effectively come "for free" once you've decided upon what resources are necessary for your system AND how you will represent those resources, and the interactions between the resources and application state.

To quote Roy Fielding

A REST API should spend almost all of its descriptive effort in defining the media type(s) used for representing resources and driving application state, or in defining extended relation names and/or hypertext-enabled mark-up for existing standard media types. Any effort spent describing what methods to use on what URIs of interest should be entirely defined within the scope of the processing rules for a media type (and, in most cases, already defined by existing media types). [Failure here implies that out-of-band information is driving interaction instead of hypertext.]

Folks always start with the URIs and think this is the solution, and then they tend to miss a key concept in REST architecture, notably, as quoted above, "Failure here implies that out-of-band information is driving interaction instead of hypertext."

To be honest, many see a bunch of URIs and some GETs and PUTs and POSTs and think REST is easy. REST is not easy. RPC over HTTP is easy, moving blobs of data back and forth proxied through HTTP payloads is easy. REST, however, goes beyond that. REST is protocol agnostic. HTTP is just very popular and apt for REST systems.

REST lives in the media types, their definitions, and how the application drives the actions available to those resources via hypertext (links, effectively).

There are different view about media types in REST systems. Some favor application specific payloads, while others like uplifting existing media types in to roles that are appropriate for the application. For example, on the one hand you have specific XML schemas designed suited to your application versus using something like XHTML as your representation, perhaps through microformats and other mechanisms.

Both approaches have their place, I think, the XHTML working very well in scenarios that overlap both the human driven and machine driven web, whereas the former, more specific data types I feel better facilitate machine to machine interactions. I find the uplifting of commodity formats can make content negotiation potentially difficult. "application/xml+yourresource" is much more specific as a media type than "application/xhtml+xml", as the latter can apply to many payloads which may or may not be something a machine client is actually interested in, nor can it determine without introspection.

However, XHTML works very well (obviously) in the human web where web browsers and rendering is very important.

You application will guide you in those kinds of decisions.

Part of the process of designing a REST system is discovering the first class resources in your system, along with the derivative, support resources necessary to support the operations on the primary resources. Once the resources are discovered, then the representation of those resources, as well as the state diagrams showing resource flow via hypertext within the representations because the next challenge.

Recall that each representation of a resource, in a hypertext system, combines both the actual resource representation along with the state transitions available to the resource. Consider each resource a node in a graph, with the links being the lines leaving that node to other states. These links inform clients not only what can be done, but what is required for them to be done (as a good link combines the URI and the media type required).

For example, you may have:

<link href="http://example.com/users" rel="users" type="application/xml+usercollection"/>
<link href="http://example.com/users?search" rel="search" type="application/xml+usersearchcriteria"/>

Your documentation will talk about the rel field named "users", and the media type of "application/xml+youruser".

These links may seem redundant, they're all talking to the same URI, pretty much. But they're not.

This is because for the "users" relation, that link is talking about the collection of users, and you can use the uniform interface to work with the collection (GET to retrieve all of them, DELETE to delete all of them, etc.)

If you POST to this URL, you will need to pass a "application/xml+usercollection" document, which will probably only contain a single user instance within the document so you can add the user, or not, perhaps, to add several at once. Perhaps your documentation will suggest that you can simply pass a single user type, instead of the collection.

You can see what the application requires in order to perform a search, as defined by the "search" link and it's mediatype. The documentation for the search media type will tell you how this behaves, and what to expect as results.

The takeaway here, though, is the URIs themselves are basically unimportant. The application is in control of the URIs, not the clients. Beyond a few 'entry points', your clients should rely on the URIs provided by the application for its work.

The client needs to know how to manipulate and interpret the media types, but doesn't much need to care where it goes.

These two links are semantically identical in a clients eyes:

<link href="http://example.com/users?search" rel="search" type="application/xml+usersearchcriteria"/>
<link href="http://example.com/AW163FH87SGV" rel="search" type="application/xml+usersearchcriteria"/>

So, focus on your resources. Focus on their state transitions in the application and how that's best achieved.

Below mentioned link gives the clear explanation with example.

[EDIT]
This answer has been edited. I'm leaving the original answer below for context (otherwise the comments wouldn't make sense).

When this question was originally asked, JSLint was the main linting tool for JavaScript. JSHint was a new fork of JSLint, but had not yet diverged much from the original.

Since then, JSLint has remained pretty much static, while JSHint has changed a great deal - it has thrown away many of JSLint's more antagonistic rules, has added a whole load of new rules, and has generally become more flexible. Also, another tool ESLint is now available, which is even more flexible and has more rule options.

In my original answer, I said that you should not force yourself to stick to JSLint's rules; as long as you understood why it was throwing a warning, you could make a judgement for yourself about whether to change the code to resolve the warning or not.

With the ultra-strict ruleset of JSLint from 2011, this was reasonable advice -- I've seen very few JavaScript codesets that could pass a JSLint test. However with the more pragmatic rules available in today's JSHint and ESLint tools, it is a much more realistic proposition to try to get your code passing through them with zero warnings.

There may still occasionally be cases where a linter will complain about something that you've done intentionally -- for example, you know that you should always use === but just this one time you have a good reason to use ==. But even then, with ESLint you have the option to specify eslint-disable around the line in question so you can still have a passing lint test with zero warnings, with the rest of your code obeying the rule. (just don't do that kind of thing too often!)

[ORIGINAL ANSWER FOLLOWS]

By all means use JSLint. But don't get hung up on the results and on fixing everything that it warns about. It will help you improve your code, and it will help you find potential bugs, but not everything that JSLint complains about turns out to be a real problem, so don't feel like you have to complete the process with zero warnings.

Some JSLint warnings are more valuable than others: learn which ones to watch out for, and which ones are less important. Every warning should be considered, but don't feel obliged to fix your code to clear any given warning; it's perfectly okay to look at the code and decide you're happy with it; there are times when things that JSlint doesn't like are actually the right thing to do.

The specific numbers in the question are from CCIR 601 (see the Wikipedia link below).

If you convert RGB -> grayscale with slightly different numbers / different methods, you won't see much difference at all on a normal computer screen under normal lighting conditions -- try it.

Here are some more links on color in general:

Should you run into "linear" vs "nonlinear" RGB, here's part of an old note to myself on this. Repeat, in practice you won't see much difference.

RGB -> ^gamma -> Y -> L*

In color science, the common RGB values, as in html rgb( 10%, 20%, 30% ), are called "nonlinear" or Gamma corrected. "Linear" values are defined as

Rlin = R^gamma,  Glin = G^gamma,  Blin = B^gamma

where gamma is 2.2 for many PCs. The usual R G B are sometimes written as R' G' B' (R' = Rlin ^ (1/gamma)) (purists tongue-click) but here I'll drop the '.

Brightness on a CRT display is proportional to RGBlin = RGB ^ gamma, so 50% gray on a CRT is quite dark: .5 ^ 2.2 = 22% of maximum brightness. (LCD displays are more complex; furthermore, some graphics cards compensate for gamma.)

To get the measure of lightness called L* from RGB, first divide R G B by 255, and compute

Y = .2126 * R^gamma + .7152 * G^gamma + .0722 * B^gamma

This is Y in XYZ color space; it is a measure of color "luminance". (The real formulas are not exactly x^gamma, but close; stick with x^gamma for a first pass.)

Finally,

L* = 116 * Y ^ 1/3 - 16

"... aspires to perceptual uniformity [and] closely matches human perception of lightness." -- Wikipedia Lab color space

<div ng-app="" ng-controller="myCntrl">

This worked for me:

$ git add .
$ git commit -m "commit"
$ git push origin master --force

Python suggests users use len() instead of __len__() for consistency, just like other guys said. However, There're some other benefits:

For some built-in types like list, str, bytearray and so on, the Cython implementation of len() takes a shortcut. It directly returns the ob_size in a C structure, which is faster than calling __len__().

If you are interested in such details, you could read the book called "Fluent Python" by Luciano Ramalho. There're many interesting details in it, and may help you understand Python more deeply.

Tried some of answers given above but those fires event twice. Here is working solution if you may need the same.

$('mydiv').one('DOMSubtreeModified', function(){
    console.log('changed');
});

You can also use replaceAll(search, replaceWith) [MDN].

Then, make sure you have a string by wrapping one type of quotes by a different type:

 'a "b" c'.replaceAll('"', "'")
 // result: "a 'b' c"
    
 'a "b" c'.replaceAll(`"`, `'`)
 // result: "a 'b' c"

 // Using RegEx. You MUST use a global RegEx(Meaning it'll match all occurrences).
 'a "b" c'.replaceAll(/\"/g, "'")
 // result: "a 'b' c"

Important(!) if you choose regex:

when using a regexp you have to set the global ("g") flag; otherwise, it will throw a TypeError: "replaceAll must be called with a global RegExp".

To set all FormGroup values use, setValue:

this.myFormGroup.setValue({
  formControlName1: myValue1, 
  formControlName2: myValue2
});

To set only some values, use patchValue:

this.myFormGroup.patchValue({
  formControlName1: myValue1, 
  // formControlName2: myValue2 (can be omitted)
});

With this second technique, not all values need to be supplied and fields whos values were not set will not be affected.

Excellent!!!

According to the latest document when state is set to be directory, you don't need to use parameter recurse to create parent directories, file module will take care of it.

- name: create directory with parent directories
  file:
    path: /data/test/foo
    state: directory

this is fare enough to create the parent directories data and test with foo

please refer the parameter description - "state" http://docs.ansible.com/ansible/latest/modules/file_module.html

sorry for answering in old thread but may my code helps other in future.i was in same scenario that when check box will be checked then few selected inputs fields will be enable other wise disabled.

$("[id*='chkAddressChange']").click(function () {
    var checked = $(this).is(':checked');
    if (checked) {
        $('.DisabledInputs').removeAttr('disabled');
    } else {
        $('.DisabledInputs').attr('disabled', 'disabled');
    }

I use GNU Cash and it uses Open Financial Exchange (ofx) http://www.ofx.net/ to download complete transactions and balances from each account of each bank.

Let me emphasize that again, you get a huge list of transactions with OFX into the GNU Cash. Depending on the account type these transactions can be very detailed description of your transactions (purchases+paycheques), investments, interests, etc.

In my case, even though I have Chase debit card I had to choose Chase Credit to make it work. But Chase wants you to enable this OFX feature by logging into your online banking and enable Quicken/MS Money/etc. somewhere in your profile or preferences. Don't call Chase customer support because they know nothing about it.

This service for OFX and GNU Cash is free. I have heard that they charge $10 a month for other platforms.

OFX can download transactions from 348 banks so far. http://www.ofxhome.com/index.php/home/directory

Actualy, OFX also supports making bill payments, stop a check, intrabank and interbank transfers etc. It is quite extensive. See it here: http://ofx.net/AboutOFX/ServicesSupported.aspx

No, you are wrong, but the direction fits ;)

The Output-Buffering buffers the output of a script. Thats (in short) everthing after echo or print. The thing with the headers is, that they only can get sent, if they are not already sent. But HTTP says, that headers are the very first of the transmission. So if you output something for the first time (in a request) the headers are sent and you can not set any other headers.

Use the ampersand just like you would from the shell.

#!/usr/bin/bash
function_to_fork() {
   ...
}

function_to_fork &
# ... execution continues in parent process ...

If you do not mind using numpy (import numpy as np):

np.partition(numbers, -2)[-2]

gives you the 2nd largest element of the list with a guaranteed worst-case O(n) running time.

The partition(a, kth) methods returns an array where the kth element is the same it would be in a sorted array, all elements before are smaller, and all behind are larger.

In my case I had installed a new version of netbeans and upgraded from java 7 to 8. The new netbeans had a different version of glassfish, so I opened the properties of my project and pointed it to the right glassfish version and set the jdk to version 8.

I just had this problem. Turns out the XML file (not the contents) was not encoded in utf-8, but in ISO-8859-1. You can check this on a Mac with file -I xml_filename.

I used Sublime to change the file encoding to utf-8, and lxml imported it no issues.

I like Zarembisty's answer. Although, if you want to be more explicit, you can always do:

if len(my_list) == 0:
    print "my_list is empty"

BOOTSTRAP 4

you can use a combination of

• fa-chevron-down, fa-chevron-up

• fa-sort-down, fa-sort-up

<th class="text-center">
    <div class="btn-group" role="group">
        <button type="button" class="btn btn-xs btn-link py-0 pl-0 pr-1">
             Some Text OR icon
        </button>
        <div class="btn-group-vertical">
            <a href="?sort=asc" class="btn btn-xs btn-link p-0">
                <i class="fas fa-sort-up"></i>
            </a>
            <a href="?sort=desc" class="btn btn-xs btn-link p-0">
                <i class="fas fa-sort-down"></i>
            </a>
        </div>
    </div>

This problem can also occur when you have conflicting tags. If your local version and remote version use same tag name for different commits, you can end up here.

You can solve it my deleting the local tag:

$ git tag --delete foo_tag

In your Lad model class, add an override to the ToString() method that returns a JSON string version of your Lad object.
Note: you will need to import System.Text.Json;

using System.Text.Json;

class MyDate
{
    int year, month, day;
}

class Lad
{
    public string firstName { get; set; };
    public string lastName { get; set; };
    public MyDate dateOfBirth { get; set; };
    public override string ToString() => JsonSerializer.Serialize<Lad>(this);
}

Try the code below. Using core Java basic functions. It takes care of Strings with extension, and without extension (without the '.' character). The case of multiple '.' is also covered.

String str = "filename.xml";
if (!str.contains(".")) 
    System.out.println("File Name=" + str); 
else {
    str = str.substring(0, str.lastIndexOf("."));
    // Because extension is always after the last '.'
    System.out.println("File Name=" + str);
}

You can adapt it to work with null strings.

None of the provided answers worked on all the browsers I tested.

It is wacky as a result of many trials; however it does work for me.

1. Open the file at location /etc/redis.conf

2. Comment out bind 127.0.0.1

3. Restart Redis:

    sudo systemctl start redis.service
   

4. Disable Firewalld:

    systemctl disable firewalld
   

5. Stop Firewalld:

    systemctl stop firewalld
   

Then try:

redis-cli -h 192.168.0.2(ip) -a redis(username)

Interface are nothing but a pure abstract class in C++. Ideally this interface class should contain only pure virtual public methods and static const data. For example:

class InterfaceA
{
public:
  static const int X = 10;

  virtual void Foo() = 0;
  virtual int Get() const = 0;
  virtual inline ~InterfaceA() = 0;
};
InterfaceA::~InterfaceA () {}

If you are using PHP, try using <?php flush(); ?> after </head> and before </body> or whatever section you want to output quickly (like the header or content). It will output the actually code without waiting for php to end. Don't use this function all the time, or the speed increase won't be noticable.

I have the same problem today, stuck on the kb2999226 for over an hour. First, i thought it is because i am using a VM on my local machine. But decided to cancel the installation, then install kb2999226 first, then install the vs2015 community again, it works out much better, the installation move forward and progressing. thx.

Do you mean to property files located in src/main/resources? Then you should exclude them using the maven-resource-plugin. See the following page for details:

http://maven.apache.org/plugins/maven-resources-plugin/examples/include-exclude.html

return b(); calls the function b(), and returns its result.

return b; returns a reference to the function b, which you can store in a variable to call later.

I was able to convert using below method for my WebAPI:

[HttpPost]
public HttpResponseMessage Post(dynamic item) // Passing parameter as dynamic
{
JArray itemArray = item["Region"]; // You need to add JSON.NET library
JObject obj = itemArray[0] as JObject;  // Converting from JArray to JObject
Region objRegion = obj.ToObject<Region>(); // Converting to Region object
}

First you might want to add

using System.Configuration;

To your .cs file. If it not available add it through the Project References as it is not included by default in a new project.

This is my solution to this problem. First I made the ConnectionProperties Class that saves the items I need to change in the original connection string. The _name variable in the ConnectionProperties class is important to be the name of the connectionString The first method takes a connection string and changes the option you want with the new value.

private String changeConnStringItem(string connString,string option, string value)
    {
        String[] conItems = connString.Split(';');
        String result = "";
        foreach (String item in conItems)
        {
            if (item.StartsWith(option))
            {
                result += option + "=" + value + ";";
            }
            else
            {
                result += item + ";";
            }
        }
        return result;
    }

You can change this method to accomodate your own needs. I have both mysql and mssql connections so I needed both of them. Of course you can refine this draft code for yourself.

private void changeConnectionSettings(ConnectionProperties cp)
{
     var cnSection = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
     String connString = cnSection.ConnectionStrings.ConnectionStrings[cp.Name].ConnectionString;
     connString = changeConnStringItem(connString, "provider connection string=\"data source", cp.DataSource);
     connString = changeConnStringItem(connString, "provider connection string=\"server", cp.DataSource);
     connString = changeConnStringItem(connString, "user id", cp.Username);
     connString = changeConnStringItem(connString, "password", cp.Password);
     connString = changeConnStringItem(connString, "initial catalog", cp.InitCatalogue);
     connString = changeConnStringItem(connString, "database", cp.InitCatalogue);
           cnSection.ConnectionStrings.ConnectionStrings[cp.Name].ConnectionString = connString;
     cnSection.Save();
     ConfigurationManager.RefreshSection("connectionStrings");
}

As I didn't want to add trivial information I ommited the Properties region of my code. Please add it if you want this to work.

class ConnectionProperties
{
    private String _name;
    private String _dataSource;
    private String _username;
    private String _password;
    private String _initCatalogue;

    /// <summary>
    /// Basic Connection Properties constructor
    /// </summary>
    public ConnectionProperties()
    {

    }

    /// <summary>
    /// Constructor with the needed settings
    /// </summary>
    /// <param name="name">The name identifier of the connection</param>
    /// <param name="dataSource">The url where we connect</param>
    /// <param name="username">Username for connection</param>
    /// <param name="password">Password for connection</param>
    /// <param name="initCat">Initial catalogue</param>
    public ConnectionProperties(String name,String dataSource, String username, String password, String initCat)
    {
        _name = name;
        _dataSource = dataSource;
        _username = username;
        _password = password;
        _initCatalogue = initCat;
    }
// Enter corresponding Properties here for access to private variables
}

I fixed this programmatically in my software, using C++ Builder.

Before I assign the CHM help file, Application->HelpFile = HelpFileName, I check to see if it contains the "Zone.Identifier" stream, and when it does, I simply remove it.

String ZIStream(HelpFileName + ":Zone.Identifier") ;

if (FileExists(ZIStream))
    { DeleteFile(ZIStream) ; }

Loading custom yml file with multiple profile config in Spring Boot.

1) Add the property bean with SpringBootApplication start up as follows

@SpringBootApplication
@ComponentScan({"com.example.as.*"})
public class TestApplication {

    public static void main(String[] args) {
        SpringApplication.run(TestApplication.class, args);
    }

    @Bean
    @Profile("dev")
    public PropertySourcesPlaceholderConfigurer propertiesStage() {
        return properties("dev");
    }

    @Bean
    @Profile("stage")
    public PropertySourcesPlaceholderConfigurer propertiesDev() {
        return properties("stage");
    }

    @Bean
    @Profile("default")
    public PropertySourcesPlaceholderConfigurer propertiesDefault() {
        return properties("default");

    }
   /**
    * Update custom specific yml file with profile configuration.
    * @param profile
    * @return
    */
    public static PropertySourcesPlaceholderConfigurer properties(String profile) {
       PropertySourcesPlaceholderConfigurer propertyConfig = null;
       YamlPropertiesFactoryBean yaml  = null;

       propertyConfig  = new PropertySourcesPlaceholderConfigurer();
       yaml = new YamlPropertiesFactoryBean();
       yaml.setDocumentMatchers(new SpringProfileDocumentMatcher(profile));// load profile filter.
       yaml.setResources(new ClassPathResource("env_config/test-service-config.yml"));
       propertyConfig.setProperties(yaml.getObject());
       return propertyConfig;
    }
}

2) Config the Java pojo object as follows

@Component
@JsonIgnoreProperties(ignoreUnknown = true)
@JsonInclude(Include.NON_NULL)
@ConfigurationProperties(prefix = "test-service")
public class TestConfig {

    @JsonProperty("id") 
    private  String id;

    @JsonProperty("name")
    private String name;

    public String getId() {
        return id;
    }

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

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }   

}

3) Create the custom yml (and place it under resource path as follows, YML File name : test-service-config.yml

Eg Config in the yml file.

test-service: 
    id: default_id
    name: Default application config
---
spring:
  profiles: dev

test-service: 
  id: dev_id
  name: dev application config

--- 
spring:
  profiles: stage

test-service: 
  id: stage_id
  name: stage application config

One Object Oriented option to replace excessively large switch and if/else constructs is to use a Chain of Responsibility Pattern to model the decision making.

Chain of Responsibility Pattern

The chain of responsibility pattern allows the separation of the source of a request from deciding which of the potentially large number of handlers for the request should action it. The class representing the chain role channels the requests from the source along the list of handlers until a handler accepts the request and actions it.

Here is an example implementation that is also Type Safe using Generics.

import java.util.ArrayList;
import java.util.List;

/**
* Generic enabled Object Oriented Switch/Case construct
* @param <T> type to switch on
*/
public class Switch<T extends Comparable<T>>

    }

    /**

     * @param c case to register
     */
    public void register(final Case<T> c) { this.cases.add(c); }

    /**
     * Run the switch logic on some input
     * @param type input to Switch on
     */
    public void evaluate(final T type)
    {
        for (final Case<T> c : this.cases)
        {
            if (c.of(type)) { break; }
        }
    }

    /**

        final Case<Integer> case1 = new EqualsCase<Integer>(1)

                if (super.type.equals(type))
                {
                    System.out.format("Case %d, break = %s\n", type, super.breakOnCompletion);
                    return super.breakOnCompletion;
                }
                else
                {
                    return false;
                }
            }
        };
        integerSwitch.register(case1);
        // more instances for each matching pattern, granted this will get verbose with lots of options but is just
        // and example of how to do standard "switch/case" logic with this pattern.
        integerSwitch.evaluate(0);
        integerSwitch.evaluate(1);
        integerSwitch.evaluate(2);


        final Switch<Integer> inRangeCaseSwitch = new Switch<Integer>();
        final Case<Integer> rangeCase = new InRangeCase<Integer>(5, 100)
        {
            @Override
            public boolean of(final Integer type)
            {
                if (super.inRange(type))
                {
                    System.out.format("Case %s is between %s and %s, break = %s\n", type, this.start, this.end, super.breakOnCompletion);
                    return super.breakOnCompletion;
                }
                else
                {
                    return false;
                }
            }
        };
        inRangeCaseSwitch.register(rangeCase);
        // run some examples
        inRangeCaseSwitch.evaluate(0);
        inRangeCaseSwitch.evaluate(10);
        inRangeCaseSwitch.evaluate(200);

        // combining both types of Case implementations
        integerSwitch.register(rangeCase);
        integerSwitch.evaluate(1);
        integerSwitch.evaluate(10);

    }
}

This is just a quick straw man that I whipped up in a few minutes, a more sophisticated implementation might allow for some kind of Command Pattern to be injected into the Case implementations instances to make it more of a call back IoC style.

Once nice thing about this approach is that Switch/Case statements are all about side affects, this encapsulates the side effects in Classes so they can be managed, and re-used better, it ends up being more like Pattern Matching in a Functional language and that isn't a bad thing.

I will post any updates or enhancements to this Gist on Github.

I have made a little example using css

  /* hide and position tooltip */_x000D_

It is pretty obvious that array[10] is faster than array.get(10), as the later internally does the same call, but adds the overhead for the function call plus additional checks.

Modern JITs however will optimize this to a degree, that you rarely have to worry about this, unless you have a very performance critical application and this has been measured to be your bottleneck.

var list = new List<string>();
var queryable = list.AsQueryable();

Add a reference to: System.Linq

IF you are checking one variable against multiple condition then you would use something like this Here the block of code where the condition is true will be executed and other blocks will be ignored.

IF(@Var1 Condition1)
     BEGIN
      /*Your Code Goes here*/
     END

ELSE IF(@Var1 Condition2)
      BEGIN
        /*Your Code Goes here*/ 
      END 

    ELSE      --<--- Default Task if none of the above is true
     BEGIN
       /*Your Code Goes here*/
     END

If you are checking conditions against multiple variables then you would have to go for multiple IF Statements, Each block of code will be executed independently from other blocks.

IF(@Var1 Condition1)
 BEGIN
   /*Your Code Goes here*/
 END


IF(@Var2 Condition1)
 BEGIN
   /*Your Code Goes here*/
 END


IF(@Var3 Condition1)
 BEGIN
   /*Your Code Goes here*/
 END

After every IF statement if there are more than one statement being executed you MUST put them in BEGIN..END Block. Anyway it is always best practice to use BEGIN..END blocks

Update

Found something in your code some BEGIN END you are missing

ELSE IF(@ID IS NOT NULL AND @ID in (SELECT ID FROM Places))   -- Outer Most Block ELSE IF

     SELECT @MyName = Name ...

          IF(@A!= @SA)
            BEGIN
             exec Store procedure 
                    @FIELD = 15,

You should always catch exceptions as concrete as possible, so you should use

try
{
    //code
}
catch (Web2PDFException ex)
{
    //Handle the exception here
}

You chould of course use something like this if you insist:

try
{
}
catch (Exception err)
{
    if (err is Web2PDFException)
    {
        //Code
    }
}

The problem here is that if there are too many data bars the labels will not show.

To fix this, under the "Chart Axis" properties set the Interval value to "=1". Then all the labels will be shown.

you want

import os
os.getcwd()
os.chdir('..')

You are calling the one.start() method in the run method of your Thread. But the run method will only be called when a thread is already started. Do this instead:

one = new Thread() {
    public void run() {
        try {
            System.out.println("Does it work?");

            Thread.sleep(1000);

            System.out.println("Nope, it doesnt...again.");
        } catch(InterruptedException v) {
            System.out.println(v);
        }
    }  
};

one.start();

This works (I feel so idiotic):

C:\Windows\System32\cmd.exe /C runas /savecred /user:OtherUser DebugTarget.Exe

The above command will ask for your password everytime, so for less frustration, you can use /savecred. You get asked only once. (but works only for Home Edition and Starter, I think)

This answer only applies to ancient versions of Visual Studio - see the more recent answers for modern versions.

You can set Visual Studio's global include path here:

Tools / Options / Projects and Solutions / VC++ Directories / Include files

It's between the Z and the C on your keyboard.

    <script>
    var scrollHeight = document.body.scrollHeight;
    var clientHeight = document.documentElement.clientHeight;
    var hasVerticalScrollbar = scrollHeight > clientHeight;

    alert(scrollHeight + " and " + clientHeight); //for checking / debugging.
    alert("hasVerticalScrollbar is " + hasVerticalScrollbar + "."); //for checking / debugging.
    </script>

This one will tell you if you have a scrollbar or not. I've included some information that may help with debugging, which will display as a JavaScript alert.

Put this in a script tag, after the closing body tag.

We can have this in 2 ways,

Either have 2 form submissions within the same View and having 2 Action methods at the controller but you will need to have the required fields to be submitted with the form to be placed within

ex is given here with code Multiple forms in view asp.net mvc with multiple submit buttons

Or

Have 2 or multiple submit buttons say btnSubmit1 and btnSubmit2 and check on the Action method which button was clicked using the code

if (Request.Form["btnSubmit1"] != null)
{
 //
}
if (Request.Form["btnSubmit2"] != null)
{
 //
}

This might help:

1) "Build" menu -> "Rebuild Project". Sometimes Intellij doesn't rewrite the classes because they already exist, this way you ask Intellij to rewrite everything.

2) "Run" menu -> "Edit configuration" -> delete the profile -> add back the profile ("Application" if it's a Java application), choose your main class from the "Main Class" dropdown menu.

3)"Build" menu -> "Rebuild Project".

Because you have a very simple CORS policy (Allow all requests from XXX domain), you don't need to make it so complicated. Try doing the following first (A very basic implementation of CORS).

If you haven't already, install the CORS nuget package.

Install-Package Microsoft.AspNetCore.Cors

In the ConfigureServices method of your startup.cs, add the CORS services.

public void ConfigureServices(IServiceCollection services)
{
    services.AddCors(); // Make sure you call this previous to AddMvc
    services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);
}

Then in your Configure method of your startup.cs, add the following :

public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
    // Make sure you call this before calling app.UseMvc()
    app.UseCors(
        options => options.WithOrigins("http://example.com").AllowAnyMethod()
    );

    app.UseMvc();
}

Now give it a go. Policies are for when you want different policies for different actions (e.g. different hosts or different headers). For your simple example you really don't need it. Start with this simple example and tweak as you need to from there.

You can access each key individually without iterating as in:

var obj = { first: 'someVal', second: 'otherVal' };
alert(Object.keys(obj)[0]); // returns first
alert(Object.keys(obj)[1]); // returns second

IMHO for Angular2 (v2.2.3) the best way is to add services that contain the global variable and inject them into components without the providers tag inside the @Component annotation. By this way you are able to share information between components.

A sample service that owns a global variable:

import { Injectable } from '@angular/core'

@Injectable()
export class SomeSharedService {
  public globalVar = '';
}

A sample component that updates the value of your global variable:

import { SomeSharedService } from '../services/index';

@Component({
  templateUrl: '...'
})
export class UpdatingComponent {

  constructor(private someSharedService: SomeSharedService) { }

  updateValue() {
    this.someSharedService.globalVar = 'updated value';
  }
}

A sample component that reads the value of your global variable:

import { SomeSharedService } from '../services/index';

@Component({
  templateUrl: '...'
})
export class ReadingComponent {

  constructor(private someSharedService: SomeSharedService) { }

  readValue() {
    let valueReadOut = this.someSharedService.globalVar;
    // do something with the value read out
  }
}

Note that providers: [ SomeSharedService ] should not be added to your @Component annotation. By not adding this line injection will always give you the same instance of SomeSharedService. If you add the line a freshly created instance is injected.

dir /s /b /a:d>output.txt will port it to a text file

for (var key in data) {
    alert("User " + data[key] + " is #" + key); // "User john is #234"
}

I don't believe you can alter an existing column to be an identity column using tsql. However, you can do it through the Enterprise Manager design view.

Alternatively you could create a new row as the identity column, drop the old column, then rename your new column.

ALTER TABLE FooTable
ADD BarColumn INT IDENTITY(1, 1)
               NOT NULL
               PRIMARY KEY CLUSTERED

First off, the extern keyword is not used for defining a variable; rather it is used for declaring a variable. I can say extern is a storage class, not a data type.

extern is used to let other C files or external components know this variable is already defined somewhere. Example: if you are building a library, no need to define global variable mandatorily somewhere in library itself. The library will be compiled directly, but while linking the file, it checks for the definition.

make sure you have added this dependency in your pom.xml

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>

There is no directive for ng-else

You can use ng-if to achieve if(){..} else{..} in angularJs.

For your current situation,

<div ng-if="data.id == 5">
<!-- If block -->
</div>
<div ng-if="data.id != 5">
<!-- Your Else Block -->
</div>

If you don't reference the imageBytes to carry bytes in the stream, the method won't return anything. Make sure you reference imageBytes = m.ToArray();

    public static byte[] SerializeImage() {
        MemoryStream m;
        string PicPath = pathToImage";

        byte[] imageBytes;
        using (Image image = Image.FromFile(PicPath)) {
            
            using ( m = new MemoryStream()) {

                image.Save(m, image.RawFormat);
                imageBytes = new byte[m.Length];
               //Very Important    
               imageBytes = m.ToArray();
                
            }//end using
        }//end using

        return imageBytes;
    }//SerializeImage

Stumbled across this answer and I actually wanted BOTH groups (data containing that one user and data containing everything but that one user). Not necessary for the specifics of this post, but I thought I would add in case someone was googling the same issue as me.

df <- data.frame(
     ran_data1=rnorm(125),
     ran_data2=rnorm(125),
     g=rep(factor(LETTERS[1:5]), 25)
 )

test_x = split(df,df$g)[['A']]
test_y = split(df,df$g!='A')[['TRUE']]

Here's what it looks like:

head(test_x)

The fact that you're getting an error from the Names Pipes Provider tells us that you're not using the TCP/IP protocol when you're trying to establish the connection. Try adding the "tcp" prefix and specifying the port number:

tcp:name.cloudapp.net,1433

I was unable to access to S3 because

• first I configured key access on the instance (it was impossible to attach role after the launch then)
• forgot about it for a few months
• attached role to instance
• tried to access. The configured key had higher priority than role, and access was denied because the user wasn't granted with necessary S3 permissions.

Solution: rm -rf .aws/credentials, then aws uses role.

Wrap each row of values to be inserted in brackets/parenthesis (value1, value2, value3) and separate the brackets/parenthesis by comma for as many as you wish to insert into the table.

INSERT INTO example

  (100, 'Name 1', 'Value 1', 'Other 1'),
  (101, 'Name 2', 'Value 2', 'Other 2'),
  (102, 'Name 3', 'Value 3', 'Other 3'),
  (103, 'Name 4', 'Value 4', 'Other 4');

FETCH_HEAD is a short-lived ref, to keep track of what has just been fetched from the remote repository.

Actually, ... not always considering that, with Git 2.29 (Q4 2020), "git fetch"^(man) learned --no-write-fetch-head option to avoid writing the FETCH_HEAD file.

See commit 887952b (18 Aug 2020) by Junio C Hamano (gitster).

fetch: optionally allow disabling FETCH_HEAD update

^{Signed-off-by: Derrick Stolee}

If you run fetch but record the result in remote-tracking branches, and either if you do nothing with the fetched refs (e.g. you are merely mirroring) or if you always work from the remote-tracking refs (e.g. you fetch and then merge origin/branchname separately), you can get away with having no FETCH_HEAD at all.

Teach "git fetch"^(man) a command line option "--[no-]write-fetch-head".

• The default is to write FETCH_HEAD, and the option is primarily meant to be used with the "--no-" prefix to override this default, because there is no matching fetch.writeFetchHEAD configuration variable to flip the default to off (in which case, the positive form may become necessary to defeat it).

Note that under "--dry-run" mode, FETCH_HEAD is never written; otherwise you'd see list of objects in the file that you do not actually have.

Passing --write-fetch-head does not force [git fetch](https://github.com/git/git/blob/887952b8c680626f4721cb5fa57704478801aca4/Documentation/git-fetch.txt)<sup>([man](https://git-scm.com/docs/git-fetch))</sup> to write the file.

fetch-options now includes in its man page:

--[no-]write-fetch-head

Write the list of remote refs fetched in the FETCH_HEAD file directly under $GIT_DIR.
This is the default.

Passing --no-write-fetch-head from the command line tells Git not to write the file.
Under --dry-run option, the file is never written.

Consider also, still with Git 2.29 (Q4 2020), the FETCH_HEAD is now always read from the filesystem regardless of the ref backend in use, as its format is much richer than the normal refs, and written directly by "git fetch"^(man) as a plain file..

refs: read FETCH_HEAD and MERGE_HEAD generically

^{Signed-off-by: Han-Wen Nienhuys}

The FETCH_HEAD and MERGE_HEAD refs must be stored in a file, regardless of the type of ref backend. This is because they can hold more than just a single ref.

To accomodate them for alternate ref backends, read them from a file generically in refs_read_raw_ref().

fetch: no FETCH_HEAD display if --no-write-fetch-head

^{Signed-off-by: Jonathan Tan}

887952b8c6 ("fetch: optionally allow disabling FETCH_HEAD update", 2020-08-18, Git v2.29.0 -- merge listed in batch #10) introduced the ability to disable writing to FETCH_HEAD during fetch, but did not suppress the "<source> -> FETCH_HEAD" message when this ability is used.

This message is misleading in this case, because FETCH_HEAD is not written.

Also, because "fetch" is used to lazy-fetch missing objects in a partial clone, this significantly clutters up the output in that case since the objects to be fetched are potentially numerous.

Therefore, suppress this message when --no-write-fetch-head is passed (but not when --dry-run is set).

mysql client can detect the output fd, if the fd is S_IFIFO(pipe) then don't output ASCII TABLES, if the fd is character device(S_IFCHR) then output ASCII TABLES.

you can use --table to force output the ASCII TABLES like:

$mysql -t -N -h127.0.0.1 -e "select id from sbtest1 limit 1" | cat
+--------+
| 100024 |
+--------+

-t, --table Output in table format.

If You want a pythonic way without numpy working in 2.7 this would be my way of doing it

l = [1,2,3,4]
_d={-1:0}
cumsum=[_d.setdefault(idx, _d[idx-1]+item) for idx,item in enumerate(l)]

now let's try it and test it against all other implementations

import timeit, sys
L=list(range(10000))
if sys.version_info >= (3, 0):
    reduce = functools.reduce
    xrange = range


def sum1(l):
    cumsum=[]
    total = 0
    for v in l:
        total += v
        cumsum.append(total)
    return cumsum


def sum2(l):
    import numpy as np
    return list(np.cumsum(l))

def sum3(l):
    return [sum(l[:i+1]) for i in xrange(len(l))]

def sum4(l):
    return reduce(lambda c, x: c + [c[-1] + x], l, [0])[1:]

def this_implementation(l):
    _d={-1:0}
    return [_d.setdefault(idx, _d[idx-1]+item) for idx,item in enumerate(l)]

One of the most interesting features in HTML5 is the ability to store data locally and to allow the application to run offline. There are three different APIs that deal with these features and choosing one depends on what exactly you want to do with the data you're planning to store locally:

1. Web storage: For basic local storage with key/value pairs
2. Offline storage: Uses a manifest to cache entire files for offline use
3. Web database: For relational database storage

For more reference see Introducing the HTML5 storage APIs

And how to use

http://cookbooks.adobe.com/post_Store_data_in_the_HTML5_SQLite_database-19115.html

My solution:

File jarToAdd = new File("/path/to/file");

new URLClassLoader(((URLClassLoader) ClassLoader.getSystemClassLoader()).getURLs()) {
    @Override
    public void addURL(URL url) {
         super.addURL(url);
    }
}.addURL(jarToAdd.toURI().toURL());

Here is example:

$array = array("Jon","Smith");
foreach($array as $value) {
  echo $value;
}

I think Nosql is "more suitable" in these scenarios at least (more supplementary is welcome)

1. Easy to scale horizontally by just adding more nodes.

2. Query on large data set

   Imagine tons of tweets posted on twitter every day. In RDMS, there could be tables with millions (or billions?) of rows, and you don't want to do query on those tables directly, not even mentioning, most of time, table joins are also needed for complex queries.

3. Disk I/O bottleneck

   If a website needs to send results to different users based on users' real-time info, we are probably talking about tens or hundreds of thousands of SQL read/write requests per second. Then disk i/o will be a serious bottleneck.

I'd first split the file into few smaller ones like this

$ split --lines=50000 /path/to/large/file /path/to/output/file/prefix

and then grep on the resulting files.

Here's an alternative regular expression:

^(?=(.{4})*$)[A-Za-z0-9+/]*={0,2}$

It satisfies the following conditions:

• The string length must be a multiple of four - (?=^(.{4})*$)
• The content must be alphanumeric characters or + or / - [A-Za-z0-9+/]*
• It can have up to two padding (=) characters on the end - ={0,2}
• It accepts empty strings

There is an Ini Parser available in CommonLibrary.NET

This has various very convenient overloads for getting sections/values and is very light weight.

int[] a = {1,2,3,4,5};

int [] b= new int[a.length]; //New Array and the size of a which is 4

Array.Copy(a,b,a.length);

Where Array is class having method Copy, which copies the element of a array to b array.

While copying from one array to another array, you have to provide same data type to another array of which you are copying.

You get this error when you wrongly add shared service to "declaration" in your appmodules instead of adding it to "provider".

You could try to do it in this way.

for u in session.query(User).all():
    print(u._asdict())

It use a built-in method in the query object that return a dictonary object of the query object.

In your component's template you can use multiple arguments by separating them with colons:

{{ myData | myPipe: 'arg1':'arg2':'arg3'... }}

From your code it will look like this:

new MyPipe().transform(myData, arg1, arg2, arg3)

And in your transform function inside your pipe you can use the arguments like this:

export class MyPipe implements PipeTransform { 
    // specify every argument individually   
    transform(value: any, arg1: any, arg2: any, arg3: any): any { }
    // or use a rest parameter
    transform(value: any, ...args: any[]): any { }
}

Beta 16 and before (2016-04-26)

Pipes take an array that contains all arguments, so you need to call them like this:

new MyPipe().transform(myData, [arg1, arg2, arg3...])

And your transform function will look like this:

export class MyPipe implements PipeTransform {    
    transform(value:any, args:any[]):any {
        var arg1 = args[0];
        var arg2 = args[1];
        ...
    }
}

If you are running windows 10 ( may be windows 7 as well ) and Android studio, Chances are that it could be because of windows virtual memory problem. See this unable to get adb version

Everything was too difficult or badly documented so I solved this with a simple script swagger-yaml-to-html.py, which works like this

python swagger-yaml-to-html.py < /path/to/api.yaml > doc.html

This is for YAML but modifying it to work with JSON is also trivial.

If you haven't downloaded the image, but you know the image URL, then you can type it in like this: href="image_url"

Hope this answered your question :-)

Kind of late to the party, but, here is another solution, which autodetects if arguments.callee is available, and uses new Error().stack if not. Tested in chrome, safari and firefox.

2 variants - stackFN(n) gives you the name of the function n away from the immediate caller, and stackArray() gives you an array, stackArray()[0] being the immediate caller.

Try it out at http://jsfiddle.net/qcP9y/6/

// returns the name of the function at caller-N
// stackFN()  = the immediate caller to stackFN
// stackFN(0) = the immediate caller to stackFN
// stackFN(1) = the caller to stackFN's caller
// stackFN(2) = and so on
// eg console.log(stackFN(),JSON.stringify(arguments),"called by",stackFN(1),"returns",retval);
function stackFN(n) {
    var r = n ? n : 0, f = arguments.callee,avail=typeof f === "function",
        s2,s = avail ? false : new Error().stack;

What's FAT?

FAT may sound like a strange name for a file system, but it's actually an acronym for File Allocation Table. Introduced in 1981, FAT is ancient in computer terms. Because of its age, most operating systems, including Microsoft Windows NT®, Windows 98, the Macintosh OS, and some versions of UNIX, offer support for FAT.

The FAT file system limits filenames to the 8.3 naming convention, meaning that a filename can have no more than eight characters before the period and no more than three after. Filenames in a FAT file system must also begin with a letter or number, and they can't contain spaces. Filenames aren't case sensitive.

What About VFAT?

Perhaps you've also heard of a file system called VFAT. VFAT is an extension of the FAT file system and was introduced with Windows 95. VFAT maintains backward compatibility with FAT but relaxes the rules. For example, VFAT filenames can contain up to 255 characters, spaces, and multiple periods. Although VFAT preserves the case of filenames, it's not considered case sensitive.

When you create a long filename (longer than 8.3) with VFAT, the file system actually creates two different filenames. One is the actual long filename. This name is visible to Windows 95, Windows 98, and Windows NT (4.0 and later). The second filename is called an MS-DOS® alias. An MS-DOS alias is an abbreviated form of the long filename. The file system creates the MS-DOS alias by taking the first six characters of the long filename (not counting spaces), followed by the tilde [~] and a numeric trailer. For example, the filename Brien's Document.txt would have an alias of BRIEN'~1.txt.

An interesting side effect results from the way VFAT stores its long filenames. When you create a long filename with VFAT, it uses one directory entry for the MS-DOS alias and another entry for every 13 characters of the long filename. In theory, a single long filename could occupy up to 21 directory entries. The root directory has a limit of 512 files, but if you were to use the maximum length long filenames in the root directory, you could cut this limit to a mere 24 files. Therefore, you should use long filenames very sparingly in the root directory. Other directories aren't affected by this limit.

You may be wondering why we're discussing VFAT. The reason is it's becoming more common than FAT, but aside from the differences I mentioned above, VFAT has the same limitations. When you tell Windows NT to format a partition as FAT, it actually formats the partition as VFAT. The only time you'll have a true FAT partition under Windows NT 4.0 is when you use another operating system, such as MS-DOS, to format the partition.

FAT32

FAT32 is actually an extension of FAT and VFAT, first introduced with Windows 95 OEM Service Release 2 (OSR2). FAT32 greatly enhances the VFAT file system but it does have its drawbacks.

The greatest advantage to FAT32 is that it dramatically increases the amount of free hard disk space. To illustrate this point, consider that a FAT partition (also known as a FAT16 partition) allows only a certain number of clusters per partition. Therefore, as your partition size increases, the cluster size must also increase. For example, a 512-MB FAT partition has a cluster size of 8K, while a 2-GB partition has a cluster size of 32K.

This may not sound like a big deal until you consider that the FAT file system only works in single cluster increments. For example, on a 2-GB partition, a 1-byte file will occupy the entire cluster, thereby consuming 32K, or roughly 32,000 times the amount of space that the file should consume. This rule applies to every file on your hard disk, so you can see how much space can be wasted.

Converting a partition to FAT32 reduces the cluster size (and overcomes the 2-GB partition size limit). For partitions 8 GB and smaller, the cluster size is reduced to a mere 4K. As you can imagine, it's not uncommon to gain back hundreds of megabytes by converting a partition to FAT32, especially if the partition contains a lot of small files.

Note: This section of the quote/ article (1999) is out of date. Updated info quote below.

As I mentioned, FAT32 does have limitations. Unfortunately, it isn't compatible with any operating system other than Windows 98 and the OSR2 version of Windows 95. However, Windows 2000 will be able to read FAT32 partitions.

The other disadvantage is that your disk utilities and antivirus software must be FAT32-aware. Otherwise, they could interpret the new file structure as an error and try to correct it, thus destroying data in the process.

Finally, I should mention that converting to FAT32 is a one-way process. Once you've converted to FAT32, you can't convert the partition back to FAT16. Therefore, before converting to FAT32, you need to consider whether the computer will ever be used in a dual-boot environment. I should also point out that although other operating systems such as Windows NT can't directly read a FAT32 partition, they can read it across the network. Therefore, it's no problem to share information stored on a FAT32 partition with other computers on a network that run older operating systems.

Updated mentioned in comment by Doktor-J (assimilated to update out of date answer in case comment is ever lost):

I'd just like to point out that most modern operating systems (WinXP/Vista/7/8, MacOS X, most if not all Linux variants) can read FAT32, contrary to what the second-to-last paragraph suggests.

The original article was written in 1999, and being posted on a Microsoft website, probably wasn't concerned with non-Microsoft operating systems anyways.

The operating systems "excluded" by that paragraph are probably the original Windows 95, Windows NT 4.0, Windows 3.1, DOS, etc.

I think the best approach to this is to keep your own record of the mouse button state, as follows:

var mouseDown = 0;
document.body.onmousedown = function() { 
    mouseDown = 1;
}
document.body.onmouseup = function() {
    mouseDown = 0;
}

and then, later in your code:

if (mouseDown == 1) {
    // the mouse is down, do what you have to do.
}

A slightly simpler method:

>>> t = ((1, 'a'),(2, 'b'))
>>> dict(map(reversed, t))
{'a': 1, 'b': 2}

Yes it is wise to use a version control system for your project. Anyway, focusing on your installation warning issue you can try to launch npm install command starting from your root project folder instead of outside of it, so the installation steps will only update the existing package-lock.json file instead of creating a new one. Hope this helps.

A fresh answer for Spring Boot 2.2 is required as server.connection-timeout=5000 is deprecated. Each server behaves differently, so server specific properties are recommended instead.

SpringBoot embeds Tomcat by default, if you haven't reconfigured it with Jetty or something else. Use server specific application properties like server.tomcat.connection-timeout or server.jetty.idle-timeout.

To test a code that depends on the System.DateTime, the system.dll must be mocked.

There are two framework that I know of that does this. Microsoft fakes and Smocks.

Microsoft fakes require visual studio 2012 ultimatum and works straight out of the compton.

Smocks is an open source and very easy to use. It can be downloaded using NuGet.

The following shows a mock of System.DateTime:

Smock.Run(context =>
{
  context.Setup(() => DateTime.Now).Returns(new DateTime(2000, 1, 1));

   // Outputs "2000"
   Console.WriteLine(DateTime.Now.Year);
});

First reset locally:

git reset 23b6772

To see if you're on the right position, verify with:

git status

You will see something like:

On branch master Your branch is behind 'origin/master' by 17 commits, and can be fast-forwarded.

Then rewrite history on your remote tracking branch to reflect the change:

git push --force-with-lease // a useful command @oktober mentions in comments

Using --force-with-lease instead of --force will raise an error if others have meanwhile committed to the remote branch, in which case you should fetch first. More info in this article.

Adding MaxHeight and VerticalScrollBarVisibility="Auto" on the DataGrid solved my problem.

I resolved by doing the following: Check if there is a module called rewrite.load in your apache at:

cd /etc/apache2/mods-enabled/

If it does not exist execute the following excerpt:

sudo a2enmod rewrite

Otherwise, change the Apache configuration file to consolidate use of the "friendly URL".

sudo nano /etc/apache2/apache2.conf

Find the following code inside the editor:

<Directory /var/www/> 
   Options Indexes FollowSymLinks
   AllowOverride None
   Require all granted
</Directory> 

Change to:

<Directory /var/www/> 
    Options Indexes FollowSymLinks
    AllowOverride All
    Require all granted
</Directory>

After that restart the Apache server via:

sudo /etc/init.d/apache2 restart

You can do it like this:

In your main view controller:

func showModal() {
    let modalViewController = ModalViewController()
    modalViewController.modalPresentationStyle = .overCurrentContext
    presentViewController(modalViewController, animated: true, completion: nil)
}

In your modal view controller:

class ModalViewController: UIViewController {
    override func viewDidLoad() {
        view.backgroundColor = UIColor.clearColor()
        view.opaque = false
    }
}

If you are working with a storyboard:

Just add a Storyboard Segue with Kind set to Present Modally to your modal view controller and on this view controller set the following values:

• Background = Clear Color
• Drawing = Uncheck the Opaque checkbox
• Presentation = Over Current Context

As Crashalot pointed out in his comment: Make sure the segue only uses Default for both Presentation and Transition. Using Current Context for Presentation makes the modal turn black instead of remaining transparent.

You can use Visual Studio - that's paid.

You can use https://www.advancedinstaller.com/ - that has a free edition.

You can use http://nsis.sourceforge.net/Main_Page - for example Winamp uses this installer - and is very configurable and is Open Source.

@SamualDavis provided a great solution in a related question, which I'll summarize here.

If you have to deserialize a JSON stream into a concrete class that has interface properties, you can include the concrete classes as parameters to a constructor for the class! The NewtonSoft deserializer is smart enough to figure out that it needs to use those concrete classes to deserialize the properties.

Here is an example:

public class Visit : IVisit
{
    /// <summary>
    /// This constructor is required for the JSON deserializer to be able
    /// to identify concrete classes to use when deserializing the interface properties.
    /// </summary>
    public Visit(MyLocation location, Guest guest)
    {
        Location = location;
        Guest = guest;
    }
    public long VisitId { get; set; }
    public ILocation Location { get;  set; }
    public DateTime VisitDate { get; set; }
    public IGuest Guest { get; set; }
}

From ES6 on you could use template strings:

let soMany = 10;
console.log(`This is ${soMany} times easier!`);
// "This is 10 times easier!

Be aware that template strings are surrounded by backticks ` instead of (single) quotes.

For further information:

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.

In year of 2020, these code seems to return exception as

System.Net.Mail.SmtpStatusCode.MustIssueStartTlsFirst or The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.7.57 SMTP; Client was not authenticated to send anonymous mail during MAIL FROM

This code is working for me.

            using (SmtpClient client = new SmtpClient()
            {
                Host = "smtp.office365.com",
                Port = 587,
                UseDefaultCredentials = false, // This require to be before setting Credentials property
                DeliveryMethod = SmtpDeliveryMethod.Network,
                Credentials = new NetworkCredential("[email protected]", "password"), // you must give a full email address for authentication 
                TargetName = "STARTTLS/smtp.office365.com", // Set to avoid MustIssueStartTlsFirst exception
                EnableSsl = true // Set to avoid secure connection exception
            })
            {

                MailMessage message = new MailMessage()
                {
                    From = new MailAddress("[email protected]"), // sender must be a full email address
                    Subject = subject,
                    IsBodyHtml = true,
                    Body = "<h1>Hello World</h1>",
                    BodyEncoding = System.Text.Encoding.UTF8,
                    SubjectEncoding = System.Text.Encoding.UTF8,

                };
                var toAddresses = recipients.Split(',');
                foreach (var to in toAddresses)
                {
                    message.To.Add(to.Trim());
                }

                try
                {
                    client.Send(message);
                }
                catch (Exception ex)
                {
                    Debug.WriteLine(ex.Message);
                }
            }

For example summer :

lblSummer.foreColor = color.Yellow;

/(?:http[s]?\/\/)?(?:[\w\-]+(?::[\w\-]+)?@)?(?:[\w\-]+\.)+(?:[a-z]{2,4})(?::[0-9]+)?(?:\/[\w\-\.%]+)*(?:\?(?:[\w\-\.%]+=[\w\-\.%!]+&?)+)?(#\w+\-\.%!)?/

You can use jsonpipe if you just need the output (and more comfortable with command line):

cat bookmarks.json | jsonpipe |grep uri

In the pom.xml (after loading effective pom.xml in eclipse), you may see it "http://repo.maven.apache.org/maven2" under central repository instead of "https://repo.maven.apache.org/maven2". Fix it

After editing .gitignore to match the ignored files, you can do git ls-files -ci --exclude-standard to see the files that are included in the exclude lists; you can then do

• Linux/MacOS: git ls-files -ci --exclude-standard -z | xargs -0 git rm --cached
• Windows (PowerShell): git ls-files -ci --exclude-standard | % { git rm --cached "$_" }
• Windows (cmd.exe): for /F "tokens=*" %a in ('git ls-files -ci --exclude-standard') do @git rm --cached "%a"

to remove them from the repository (without deleting them from disk).

Edit: You can also add this as an alias in your .gitconfig file so you can run it anytime you like. Just add the following line under the [alias] section (modify as needed for Windows or Mac):

apply-gitignore = !git ls-files -ci --exclude-standard -z | xargs -0 git rm --cached

(The -r flag in xargs prevents git rm from running on an empty result and printing out its usage message, but may only be supported by GNU findutils. Other versions of xargs may or may not have a similar option.)

Now you can just type git apply-gitignore in your repo, and it'll do the work for you!

Using jQuery:

$(function() {
    window.isActive = true;
    $(window).focus(function() { this.isActive = true; });
    $(window).blur(function() { this.isActive = false; });
    showIsActive();
});

function showIsActive()
{
    console.log(window.isActive)
    window.setTimeout("showIsActive()", 2000);
}

function doWork()
{
    if (window.isActive) { /* do CPU-intensive stuff */}
}

You have a few different options:

• you can use a SPA router like SammyJS, or Angularjs and ui-router, so your pages are stateful.
• use sessionStorage to store your state.
• store the values on the URL hash.

Use Insert method: list.Insert(0, item);

For Python 3 below eliminates overhead of list conversion:

first = next(iter(prices.values()))

It's simple-

SELECT empname,
       empid,
       (SELECT COUNT (profileid)
          FROM profile
         WHERE profile.empid = employee.empid)
           AS number_of_profiles
  FROM employee;

It is even simpler when you use a table join like this:

  SELECT e.empname, e.empid, COUNT (p.profileid) AS number_of_profiles
    FROM employee e LEFT JOIN profile p ON e.empid = p.empid
GROUP BY e.empname, e.empid;

Explanation for the subquery:

Essentially, a subquery in a select gets a scalar value and passes it to the main query. A subquery in select is not allowed to pass more than one row and more than one column, which is a restriction. Here, we are passing a count to the main query, which, as we know, would always be only a number- a scalar value. If a value is not found, the subquery returns null to the main query. Moreover, a subquery can access columns from the from clause of the main query, as shown in my query where employee.empid is passed from the outer query to the inner query.

Edit:

When you use a subquery in a select clause, Oracle essentially treats it as a left join (you can see this in the explain plan for your query), with the cardinality of the rows being just one on the right for every row in the left.

Explanation for the left join

A left join is very handy, especially when you want to replace the select subquery due to its restrictions. There are no restrictions here on the number of rows of the tables in either side of the LEFT JOIN keyword.

For more information read Oracle Docs on subqueries and left join or left outer join.

The following solution is working for IE9, IE8, Chrome, and FF newer versions as of 2014-03-10. The scenario is this: you are in a window (A), where you click a button/link to launch the printing process, then a new window (B) with the contents to be printed is opened, the printing dialog is shown immediately, and you can either cancel or print, and then the new window (B) closes automatically.

The following code allows this. This javascript code is to be placed in the html for window A (not for window B):

/**
 * Opens a new window for the given URL, to print its contents. Then closes the window.
 */
function openPrintWindow(url, name, specs) {
  var printWindow = window.open(url, name, specs);
    var printAndClose = function() {
        if (printWindow.document.readyState == 'complete') {
            clearInterval(sched);
            printWindow.print();
            printWindow.close();
        }
    }
    var sched = setInterval(printAndClose, 200);
};

The button/link to launch the process has simply to invoke this function, as in:

openPrintWindow('http://www.google.com', 'windowTitle', 'width=820,height=600');

First-level cache

Hibernate tries to defer the Persistence Context flushing up until the last possible moment. This strategy has been traditionally known as transactional write-behind.

The write-behind is more related to Hibernate flushing rather than any logical or physical transaction. During a transaction, the flush may occur multiple times.

The flushed changes are visible only for the current database transaction. Until the current transaction is committed, no change is visible by other concurrent transactions.

Due to the first-level cache, Hibernate can do several optimizations:

• JDBC statement batching
• prevent lost update anomalies

Second-level cache

A proper caching solution would have to span across multiple Hibernate Sessions and that’s the reason Hibernate supports an additional second-level cache as well.

The second-level cache is bound to the SessionFactory life-cycle, so it’s destroyed only when the SessionFactory is closed (typically when the application is shutting down). The second-level cache is primarily entity-based oriented, although it supports an optional query-caching solution as well.

When loading an entity, Hibernate will execute the following actions:

1. If the entity is stored in the first-level cache, then the cached object reference is returned. This ensures application-level repeatable reads.
2. If the entity is not stored in the first-level cache and the second-level cache is activated, then Hibernate checks if the entity has been cached in the second-level cache, and if it were, it returns it to the caller.
3. Otherwise, if the entity is not stored in the first or second-level cache, it will be loaded from the DB.

Maybe try this:

yum -y groupinstall "MYSQL Database Client"

For a nice quick and dirty creation/replacement of a crontab from with a BASH script, I used this notation:

crontab <<EOF
00 09 * * 1-5 echo hello
EOF

I usually do it this way when it's a quite a few rows:

1. Select all sproc parameters in a dataset with SQL Management Studio
2. Right-click -> Copy
3. Paste in to excel
4. Create single-row sql statements with a formula like '="EXEC schema.mysproc @param=" & A2' in a new excel column. (Where A2 is your excel column containing the parameter)
5. Copy the list of excel statements into a new query in SQL Management Studio and execute.
6. Done.

(On larger datasets i'd use one of the solutions mentioned above though).

private static InetAddress getLocalAddress(){
        try {
            Enumeration<NetworkInterface> b = NetworkInterface.getNetworkInterfaces();
            while( b.hasMoreElements()){
                for ( InterfaceAddress f : b.nextElement().getInterfaceAddresses())
                    if ( f.getAddress().isSiteLocalAddress())
                        return f.getAddress();
            }
        } catch (SocketException e) {
            e.printStackTrace();
        }
        return null;
    }

What you're looking for is serialization. There are several forms of serialization available for the .Net platform

• Binary Serialization
• XML Serialization: Produces a string which is easily convertible to a byte[]
• ProtoBuffers

After a bit of investigation, turns out that Safari on iOS6 will cache POSTs that have either no Cache-Control headers or even "Cache-Control: max-age=0".

The only way I've found of preventing this caching from happening at a global level rather than having to hack random querystrings onto the end of service calls is to set "Cache-Control: no-cache".

So:

• No Cache-Control or Expires headers = iOS6 Safari will cache
• Cache-Control max-age=0 and an immediate Expires = iOS6 Safari will cache
• Cache-Control: no-cache = iOS6 Safari will NOT cache

I suspect that Apple is taking advantage of this from the HTTP spec in section 9.5 about POST:

Responses to this method are not cacheable, unless the response includes appropriate Cache-Control or Expires header fields. However, the 303 (See Other) response can be used to direct the user agent to retrieve a cacheable resource.

So in theory you can cache POST responses...who knew. But no other browser maker has ever thought it would be a good idea until now. But that does NOT account for the caching when no Cache-Control or Expires headers are set, only when there are some set. So it must be a bug.

Below is what I use in the right bit of my Apache config to target the whole of my API because as it happens I don't actually want to cache anything, even gets. What I don't know is how to set this just for POSTs.

Header set Cache-Control "no-cache"

Update: Just noticed that I didn't point out that it is only when the POST is the same, so change any of the POST data or URL and you're fine. So you can as mentioned elsewhere just add some random data to the URL or a bit of POST data.

Update: You can limit the "no-cache" just to POSTs if you wish like this in Apache:

SetEnvIf Request_Method "POST" IS_POST
Header set Cache-Control "no-cache" env=IS_POST

Well, .html() uses .innerHTML which is faster than DOM creation.

With zsh ohmyzsh I added this to the .zshrc:

 # You may need to manually set your language environment
 LANGUAGE=en_US.UTF-8
 LANG=en_US.UTF-8
 LC_CTYPE=en_US.UTF-8
 LC_ALL=en_US.UTF-8

By removing the line export LANG=en_US.UTF-8

Reopened a new tab and SSHed in, worked for me :)

I am having the same issue when trying to upgrade Android Studio from 1.1 to 1.2 on Mac OS 10.10. I solved the problem by selecting custom installation instead of standard. Also we need to select the Android SDK Platform (Lollipop 5.1).

Facebook uses the LAMP stack, so if you want to get a career with them you're going to want to focus on that. In addition they often have C++ and/or Java listed in their requirements as well.

One of the postings includes the following requirements:

• Expertise with C++ and/or Java
• Knowledge of Perl or PHP or Python
• Knowledge of relational databases and SQL, preferably MySQL and Oracle

Another:

• Expertise in PHP, JavaScript, and CSS.

Another:

• Knowledge of Perl or PHP or Python
• Knowledge of relational databases and

Also, do any other social networking sites use the same language?

Some other companys that use PHP/LAMP Stack:

• DeviantArt (more focused on art)
• Twitter (for Front-End development)
• Google+

I was able to get this working using the answer found here:

How to git commit nothing without an error?

git diff --quiet --exit-code --cached || git commit -m 'bla'

The cunningly-named urlencode() and urldecode().

However, you shouldn't need to use urldecode() on variables that appear in $_POST and $_GET.

Is this acceptable?

var child = document.createElement('div');
child.innerHTML = str;
child = child.firstChild;
document.getElementById('test').appendChild(child);

jsFiddle.

But, Neil's answer is a better solution.

if ($done)
{
    header("Location: /url/to/the/other/page");
    exit;
}

Just run into this one of longest thread, below is my solution:

parseFloat(Math.round((parseFloat(num * 100)).toFixed(2)) / 100 ).toFixed(2)

Let me know if anyone can poke a hole

The answer, u, (and many others) is in $ vimtutor.

This is a hack to make inner functions (functions defined inside other functions) work more like they should. In javascript when you define one function inside another this automatically gets set to the global scope. This can be confusing because you expect this to have the same value as in the outer function.

var car = {};
car.starter = {};

car.start = function(){
    var that = this;

    // you can access car.starter inside this method with 'this'
    this.starter.active = false;

    var activateStarter = function(){
        // 'this' now points to the global scope
        // 'this.starter' is undefined, so we use 'that' instead.
        that.starter.active = true;

        // you could also use car.starter, but using 'that' gives
        // us more consistency and flexibility
    };

    activateStarter();

};

This is specifically a problem when you create a function as a method of an object (like car.start in the example) then create a function inside that method (like activateStarter). In the top level method this points to the object it is a method of (in this case, car) but in the inner function this now points to the global scope. This is a pain.

Creating a variable to use by convention in both scopes is a solution for this very general problem with javascript (though it's useful in jquery functions, too). This is why the very general sounding name that is used. It's an easily recognizable convention for overcoming a shortcoming in the language.

Like El Ronnoco hints at Douglas Crockford thinks this is a good idea.

If you have the XML stored inside a string variable you could use a StringReader:

var xml = @"<car/>";
var serializer = new XmlSerializer(typeof(Car));
using (var reader = new StringReader(xml))
{
    var car = (Car)serializer.Deserialize(reader);
}

$newstr = preg_replace('/[^a-zA-Z0-9\']/', '_', "There wouldn't be any");
$newstr = str_replace("'", '', $newstr);

I put them on two separate lines to make the code a little more clear.

Note: If you're looking for Unicode support, see Filip's answer below. It will match all characters that register as letters in addition to A-z.

For measuring distances with a single camera, you need to know some numbers. To measure height of something, say a chair, the only thing you have is the the size of it in the camera (which is in pixels, and can be converted to inches using screen size), that is all. The chance of measuring the height and width is using a reference, say a 6 foot tall person standing next to the chair.

This way you can work out in reverse using say a 10 foot tall object, using its size as appearing in the camera, you can work out the size of things at the same distance, on a surface that is not flat, even ensuring that they are at the same distance is a challenge.

So using the camera and just the camera, it is not possible. You need to know distance somehow, or need a reference.

If you are using the application to measure height of items you know the location of, then using GPS, you can find distance, and rest is math.

I have found some links using Google, they may help.

1. http://forestjohnson.blogspot.com/2010/01/how-to-measure-size-of-object-using.html
2. http://gigaom.com/mobile/how_to_measure_/
3. http://www.iphonelife.com/blog/5/cameasure-use-your-camera-measure-size-or-distance

They may help you to find out what other information is needed other than what the camera can provide, so that you can think about your application as well regarding what can be done and what are the limitations.

One way is using multiple cameras, and that can be compensated using multiple pictures taken a known distance away. So the application can ask the user to take multiple images, track the distance using GPS, and probably it can work.

See these links as well:

It's unfortunate that it seems JavaScript has no simple way to validate a date string to these days. This is the simplest way I can think of to parse dates in the format "m/d/yyyy" in modern browsers (that's why it doesn't specify the radix to parseInt, since it should be 10 since ES5):

const dateValidationRegex = /^\d{1,2}\/\d{1,2}\/\d{4}$/;_x000D_
function isValidDate(strDate) {_x000D_
  if (!dateValidationRegex.test(strDate)) return false;_x000D_
  const [m, d, y] = strDate.split('/').map(n => parseInt(n));_x000D_
  return m === new Date(y, m - 1, d).getMonth() + 1;_x000D_
}_x000D_
_x000D_
['10/30/2000abc', '10/30/2000', '1/1/1900', '02/30/2000', '1/1/1/4'].forEach(d => {_x000D_
  console.log(d, isValidDate(d));_x000D_
});

Coming from SQL Server as well, and this really bugged me. For those using Toad Data Point or Toad for Oracle, it's extremely simple. Just putting a colon in front of your variable name will prompt Toad to open a dialog where you enter the value on execute.

SELECT * FROM some_table WHERE some_column = :var_name;

Here's my solution, just pass in a parseable date:

function getAge(birth) {
  ageMS = Date.parse(Date()) - Date.parse(birth);
  age = new Date();
  age.setTime(ageMS);
  ageYear = age.getFullYear() - 1970;

  return ageYear;

  // ageMonth = age.getMonth(); // Accurate calculation of the month part of the age
  // ageDay = age.getDate();    // Approximate calculation of the day part of the age
}
