My solution was to use the "-OutBuffer 2147483647" parameter in my query, which is part of the Common Parameters. PS C:> Get-Help about_CommonParameters -Full

This may help you. I may be mistaken but it seems to me that this is related with returning START_STICKY in your onStartCommand() method. You can avoid the service from being called again by returning START_NOT_STICKY instead.

pgrep -f <your process name> | xargs kill -9

This will kill the your process service. In my case it is

pgrep -f python | xargs kill -9

Try this:

string[] computer_name = System.Net.Dns.GetHostEntry(System.Web.HttpContext.Current.Request.ServerVariables["remote_addr"]).HostName.Split(new Char[] { '.' });
return computer_name[0].ToString();

Installing XCode requires:

• Enrolling on the Apple website (not fun)
• Downloading a 4.7G installer

To install g++ *WITHOUT* having to download the MASSIVE 4.7G xCode install, try this package:

https://github.com/kennethreitz/osx-gcc-installer

The DMG files linked on that page are ~270M and much quicker to install. This was perfect for me, getting homebrew up and running with a minimum of hassle.

The github project itself is basically a script that repackages just the critical chunks of xCode for distribution. In order to run that script and build the DMG files, you'd need to already have an XCode install, which would kind of defeat the point, so the pre-built DMG files are hosted on the project page.

I killed all the java TM processes in the task manager and it let me to rebuild

This works for me:

File f = new File("some.properties");
Properties props = new Properties();
FileInputStream fis = null;
try {
    fis = new FileInputStream(f);
    props.load(fis);
} catch (FileNotFoundException e) {
    e.printStackTrace();                    
} catch (IOException e) {
    e.printStackTrace();
} finally {
    if (fis != null) {
        try {
            fis.close();
            fis = null;
        } catch (IOException e2) {
            e2.printStackTrace();
        }
    }
}           

If nothing of the above helps, check if there is margin-top set on some of the (some levels below) nested DOM element(s).

It will be not recognizable when you inspect body element itself in the debugger. It will only be visible when you unfold several elements nested down in body element in Chrome Dev Tools elements debugger and check if there is one of them with margin-top set.

The below is the upper part of a site screen shot and the corresponding Chrome Dev Tools view when you inspect body tag.

No sign of top margin here and you have resetted all the browser-scpecific CSS properties as per answers above but that unwanted white space is still here.

The following is a view when you inspect the right nested element. It is clearly seen the orange'ish top-margin is set on it. This is the one that causes the white space on top of body element.

On that found element replace margin-top with padding-top if you need space above it and yet not to leak it above the body tag.

Hope that helps :)

There is a simple and very common technique by using 2 background images: a crisp and a blurry one. You set the crisp image as a background for the body and the blurry one as a background image for your container. The blurry image must be set to fixed positioning and the alignment is 100% perfect. I used it before and it works.

body {
    background: url(yourCrispImage.jpg) no-repeat;
}

#container {
    background: url(yourBlurryImage.jpg) no-repeat fixed;
}

You can see a working example at the following fiddle: http://jsfiddle.net/jTUjT/5/. Try to resize the browser and see that the alignment never fails.

If only CSS element() was supported by other browsers other than Mozilla's -moz-element() you could create great effects. See this demo with Mozilla.

Verify what are you attempting to write. I was having the same issue, but I realized i was trying to write a byte array with length of 0.

It doesn't make sense to me, but I get: "Access to the path "

There was an issue in coredns pod, I deleted such pod by

kubectl delete pod -n=kube-system coredns-fb8b8dccf-8ggcf

Its pod will restart automatically.

You probably shouldn't rely on textual output of a command to decide this, especially when the ping command gives you a perfectly good return value:

The ping utility returns an exit status of zero if at least one response was heard from the specified host; a status of two if the transmission was successful but no responses were received; or another value from <sysexits.h> if an error occurred.

In other words, use something like:

((count = 100))                            # Maximum number to try.
while [[ $count -ne 0 ]] ; do
    ping -c 1 8.8.8.8                      # Try once.
    rc=$?
    if [[ $rc -eq 0 ]] ; then
        ((count = 1))                      # If okay, flag to exit loop.
    fi
    ((count = count - 1))                  # So we don't go forever.
done

if [[ $rc -eq 0 ]] ; then                  # Make final determination.
    echo `say The internet is back up.`
else
    echo `say Timeout.`
fi

Migration to TestNG seems the best way, but I see no clear solution here for jUnit. Here is most readable solution / formatting I found for jUnit:

@FixMethodOrder(MethodSorters.NAME_ASCENDING)
public class SampleTest {
    @Test
    void stage1_prepareAndTest(){};

    @Test
    void stage2_checkSomething(){};

    @Test
    void stage2_checkSomethingElse(){};

    @Test
    void stage3_thisDependsOnStage2(){};

    @Test
    void callTimeDoesntMatter(){}
}

This ensures stage2 methods are called after stage1 ones and before stage3 ones.

Everyone should try this jQuery plugin: xautoresize-jquery. It's really good and should solve your problem.

try this

<iframe name="myIframe" id="myIframe" width="400px" height="400px" runat="server"></iframe>

Expose this iframe in the master page's codebehind:

public HtmlControl iframe
{
get
{
return this.myIframe;
}
}

Add the MasterType directive for the content page to strongly typed Master Page.

<%@ Page Language="C#" MasterPageFile="~/MasterPage.master" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits=_Default" Title="Untitled Page" %>
<%@ MasterType VirtualPath="~/MasterPage.master" %>

In code behind

protected void Page_Load(object sender, EventArgs e)
{
this.Master.iframe.Attributes.Add("src", "some.aspx");
}

[Update]

The original answer was written prior to jQuery 1.3, and the functions that existed at the time where not adequate by themselves to calculate the whole width.

Now, as J-P correctly states, jQuery has the functions outerWidth and outerHeight which include the border and padding by default, and also the margin if the first argument of the function is true

[Original answer]

The width method no longer requires the dimensions plugin, because it has been added to the jQuery Core

What you need to do is get the padding, margin and border width-values of that particular div and add them to the result of the width method

Something like this:

var theDiv = $("#theDiv");
var totalWidth = theDiv.width();
totalWidth += parseInt(theDiv.css("padding-left"), 10) + parseInt(theDiv.css("padding-right"), 10); //Total Padding Width
totalWidth += parseInt(theDiv.css("margin-left"), 10) + parseInt(theDiv.css("margin-right"), 10); //Total Margin Width
totalWidth += parseInt(theDiv.css("borderLeftWidth"), 10) + parseInt(theDiv.css("borderRightWidth"), 10); //Total Border Width

Split into multiple lines to make it more readable

That way you will always get the correct computed value, even if you change the padding or margin values from the css

Fundamentally, the issue has to do with not being able to get MTP+ADB working while for example PTP+ADB may work. In my case when I plugged Nexus 5, windows 7 will install only MTP driver completely ignoring ADB. I couldn't find a good solution for this problem anywhere else so here I provide steps (some of the steps I copied from other sources):

0) Unplug Nexus 5. Make sure you selected MTP and ADB.

1) Make sure that sdk\extras\google\usb_driverandroid_winusb.inf in Google SDK had the following lines (in two places in that file):

;Google Nexus (generic)

%CompositeAdbInterface% = USB_Install, USB\VID_18D1&PID_4EE2&MI_01

NOTE: VID_18D1 is Google VID, PID_4EE2 is PID for MTP+ADB, MI_01 means that ADB is on interface 1 (MTP is on interface 0).

You can check what is on what interface by plugging Nexus 5 into a Linux system and typing lsusb.

2) first delete all installed Google USB drivers. One good tool is called USBDeview and can be find at the following location: http://www.nirsoft.net/utils/usb_devices_view.html Download the tool and run it (there is no need to install it). Take a look at the colored status indicator on the far-left of the USBDeview window. Green indicates the the device functions properly. Pink means the device can unplug and works properly (although it may not actually work properly). Red indicates a disabled USB device. Gray (circled, below) means the device is installed, but not connected. Second, remove all gray items with the words “Google”, “Linux”, “ADB”, or “Android” in the title.

3) Now delete old cached Google *.inf files. Open a Windows Explorer and navigate to the C:\Windows\INF directory. Somewhere in there there is an "oemN.inf" file (where N is a number that will vary on your system) that is a copy of the android_usb.inf -- the thing to do is to find which file and remove it. Windows keeps a cache of the INF files here and what we found is that sometimes an older cached copy is used instead of a newer version.

One simple way to find which one using the Windows Explorer: - In the explorer's Search box, enter "androidwinusb86.cat" without the quotes. - Typically the search will be empty because no filename has this pattern. - Go to Tools/Folder Options, click Search Tab and click Always search file name and contents. Click Apply - Search again. This time it should list a few files such as "oem90.inf" (you'll have one or more, with different numbers).

Now use the Windows Explorer and delete the "oemNN.*" files that matched above (only those with androidwinusb in them.).

4) We now want to disable installation of MTP by windows before windows discovers ADB. Now search for wpdmtp.* files in the same directory. Presence of these files will force install MTP disregarding ADB class in the same (composite) device. Move these files out of \inf folder

5) plug in the device again. This time, both MTP and Android ADB driver installation will fail.

6) Find Other devices in the Device Manager and when expanded it should show Nexus 5 and MTP. Right click and update Nexus 5 by navigating to the sdk\extras\google\usb_driver\android_winusb.inf.

Move wpdmtp.* files back to \inf folder. Right click MTP device and update.

7) If necessary, confirm on your Nexus 5 that this PC has access to the phone.

8) If everything went as expected you should see in Device Manager the following:

• Expand Android Device. Right click Android Composite ADB Interface, select Properties, choose tab Details, under Property select Hardware Ids. You should see USB\VID_18D1&PID_4EE2&MI_01

• Expand Portable devices. Right click Nexus 5, select Properties, choose tab Details, under Property select Hardware Ids. You should see USB\VID_18D1&PID_4EE2&MI_00

I think you should call the super.draw() method first before you do anything in surfaceView's draw method.

A simple Example:

On any Element you have to add an attribute ref with a unique value

<input ref="foo" type="text" >

To target that elemet use this.$refs.foo

this.$refs.foo.focus(); // it will focus the input having ref="foo"

My final solution

class DynamicModeTabLayout : TabLayout {

    constructor(context: Context?) : super(context)
    constructor(context: Context?, attrs: AttributeSet?) : super(context, attrs)
    constructor(context: Context?, attrs: AttributeSet?, defStyleAttr: Int) : super(context, attrs, defStyleAttr)

    override fun setupWithViewPager(viewPager: ViewPager?) {
        super.setupWithViewPager(viewPager)

        val view = getChildAt(0) ?: return
        view.measure(MeasureSpec.UNSPECIFIED, MeasureSpec.UNSPECIFIED)
        val size = view.measuredWidth

        if (size > measuredWidth) {
            tabMode = MODE_SCROLLABLE
            tabGravity = GRAVITY_CENTER
        } else {
            tabMode = MODE_FIXED
            tabGravity = GRAVITY_FILL
        }
    }
}

You can use pandas methods where and mask:

df['color'] = 'green'
df['color'] = df['color'].where(df['Set']=='Z', other='red')
# Replace values where the condition is False

or

df['color'] = 'red'
df['color'] = df['color'].mask(df['Set']=='Z', other='green')
# Replace values where the condition is True

Output:

  Type Set  color
1    A   Z  green
2    B   Z  green
3    B   X    red
4    C   Y    red

The DATEADD() function adds or subtracts a specified time interval from a date.

DATEADD(datepart,number,date)

datepart(interval) can be hour, second, day, year, quarter, week etc; number (increment int); date(expression smalldatetime)

For example if you want to add 30 days to current date you can use something like this

 select dateadd(dd, 30, getdate())

To Substract 30 days from current date

select dateadd(dd, -30, getdate())

If anybody else had a problem with best answer's solution (including disabling foreign keys), here is another solution from me:

-- CLEAN DB
USE [DB_NAME]
    EXEC sp_MSForEachTable 'ALTER TABLE ? NOCHECK CONSTRAINT ALL'
    EXEC sp_MSForEachTable 'DELETE FROM ?'

    DECLARE @Sql NVARCHAR(500) DECLARE @Cursor CURSOR
    SET @Cursor = CURSOR FAST_FORWARD FOR

    SELECT DISTINCT sql = 'ALTER TABLE [' + tc2.TABLE_NAME + '] DROP [' + rc1.CONSTRAINT_NAME + ']'
    FROM INFORMATION_SCHEMA.REFERENTIAL_CONSTRAINTS rc1
    LEFT JOIN INFORMATION_SCHEMA.TABLE_CONSTRAINTS tc2 ON tc2.CONSTRAINT_NAME =rc1.CONSTRAINT_NAME
    OPEN @Cursor FETCH NEXT FROM @Cursor INTO @Sql
    WHILE (@@FETCH_STATUS = 0)
      BEGIN
        Exec SP_EXECUTESQL @Sql
        FETCH NEXT 
        FROM @Cursor INTO @Sql
      END
    CLOSE @Cursor DEALLOCATE @Cursor
    GO

    EXEC sp_MSForEachTable 'DROP TABLE ?'
    GO

    EXEC sp_MSForEachTable 'ALTER TABLE ? WITH CHECK CHECK CONSTRAINT ALL'

For method decorator declaration with configuration "noImplicitAny": true, you can specify type of this variable explicitly depends on @tony19's answer

function logParameter(this:any, target: Object, propertyName: string) {
  //...
}

A clean solution could be create a generic class to handle the list, so you don't need to create a different class each time you need it.

public class ListModel<T>
{
    public List<T> Items { get; set; }

    public ListModel(List<T> list) {
        Items = list;
    }
}

and when you return the View you just need to simply do:

List<customClass> ListOfCustomClass = new List<customClass>();
//Do as needed...
return View(new ListModel<customClass>(ListOfCustomClass));

then define the list in the model:

@model ListModel<customClass>

and ready to go:

@foreach(var element in Model.Items) {
  //do as needed...
}

I thought this is a simpler script if you want to remove all quotes

UPDATE Table_Name
SET col_name = REPLACE(col_name, '"', '')

In order to have it working with negative numbers and a long list you can do the following:

b = numpy.flipud(numpy.array(a.split(),float))

Where flipud is for 1d arra

Think of a method as giving a task to a coworker. A simple task might be the following:

Solve these equations:
x + 2 = y
2 * x = 3 * y

Your coworker diligently does the math and gives you the following result:

x = -6
y = -4

But your coworker has a problem, he doesn't always understand notations, such as ^, but he does understand them by their description. Such as exponent. Everytime he finds one of these you get back the following:

I don't understand "^"

This requires you to rewrite your entire instruction set again after explaining what the character means to your coworker, and he doesn't always remember in between questions. And he has difficulty remembering your tips as well, such as just ask me. He always follows your written directions as best he can however.

You think of a solution, you just add the following to all of your instructions:

If you have any questions about symbols, call me at extension 1234 and I will tell you its name.

Now whenever he has a problem he calls you and asks, rather than giving you a bad response and making the process restart.

You can trigger a newline by inserting Chunk.NEWLINE into your document. Here's an example.

public static void main(String args[]) {
    try {
        // create a new document
        Document document = new Document( PageSize.A4, 20, 20, 20, 20 );
        PdfWriter.getInstance( document, new FileOutputStream( "HelloWorld.pdf" ) );

        document.open();

        document.add( new Paragraph( "Hello, World!" ) );
        document.add( new Paragraph( "Hello, World!" ) );

        // add a couple of blank lines
        document.add( Chunk.NEWLINE );
        document.add( Chunk.NEWLINE );

        // add one more line with text
        document.add( new Paragraph( "Hello, World!" ) );

        document.close();
    }
    catch (Exception e) {
        e.printStackTrace();
    }
}

Below is a screen shot showing part of the PDF that the code above produces.

This works the best for me:

The Like Box/ Page plugin is basically an iframe and ugly :D

So I created my own free plugin that I call Famax plugin to display FanPage feeds. It's similar to the like box but has a better UI and is more customizable.

Also because the Like box is shown in an iframe with a fixed width and height etc, its not really responsive.

What is the difference between them?

Image: the generic Linux kernel binary image file.

zImage: a compressed version of the Linux kernel image that is self-extracting.

uImage: an image file that has a U-Boot wrapper (installed by the mkimage utility) that includes the OS type and loader information.
A very common practice (e.g. the typical Linux kernel Makefile) is to use a zImage file. Since a zImage file is self-extracting (i.e. needs no external decompressors), the wrapper would indicate that this kernel is "not compressed" even though it actually is.

Note that the author/maintainer of U-Boot considers the (widespread) use of using a zImage inside a uImage questionable:

Actually it's pretty stupid to use a zImage inside an uImage. It is much better to use normal (uncompressed) kernel image, compress it using just gzip, and use this as poayload for mkimage. This way U-Boot does the uncompresiong instead of including yet another uncompressor with each kernel image.

(quoted from https://lists.yoctoproject.org/pipermail/yocto/2013-October/016778.html)

Which type of kernel image do I have to use?

You could choose whatever you want to program for.
For economy of storage, you should probably chose a compressed image over the uncompressed one.
Beware that executing the kernel (presumably the Linux kernel) involves more than just loading the kernel image into memory. Depending on the architecture (e.g. ARM) and the Linux kernel version (e.g. with or without DTB), there are registers and memory buffers that may have to be prepared for the kernel. In one instance there was also hardware initialization that U-Boot performed that had to be replicated.

ADDENDUM

I know that u-boot needs a kernel in uImage format.

That is accurate for all versions of U-Boot which only have the bootm command.
But more recent versions of U-Boot could also have the bootz command that can boot a zImage.

I use:

body.modal-open .datepicker {
    z-index: 1200 !important;
}

This way: if the modal isn't open, and you want the datepicker to be at the normal z-index (in my case I needed it to be under the menu drop-down, which has a z-index of 1000), it works.

If the modal is open, the datepicker needs to be over the modal z-index (1040 or 1050), so use the body.modal-open selector.

I'm using Bootstrap 3.1.1

This is how to get JavaScriptSerializer available in your application, targetting .NET 4.0 (full)

using System.Web.Script.Serialization;

This should allow you to create a new JavaScriptSerializer object!

First, given that you have a complex data retrieval scenario, are you sure even SQLite is overkill?

You'll end up having an ad hoc, informally-specified, bug-ridden, slow implementation of half of SQLite, paraphrasing Greenspun's Tenth Rule.

That said, you are very right in saying that choosing a single data structure will impact one or more of searching, sorting or counting, so if performance is paramount and your data is constant, you could consider having more than one structure for different purposes.

Above all, measure what operations will be more common and decide which structure will end up costing less.

I've wrapped Darin's answer into a nicely reusable extension method.

public static class UriExtensions
{
    /// <summary>
    /// Adds the specified parameter to the Query String.
    /// </summary>
    /// <param name="url"></param>
    /// <param name="paramName">Name of the parameter to add.</param>
    /// <param name="paramValue">Value for the parameter to add.</param>
    /// <returns>Url with added parameter.</returns>
    public static Uri AddParameter(this Uri url, string paramName, string paramValue)
    {
        var uriBuilder = new UriBuilder(url);
        var query = HttpUtility.ParseQueryString(uriBuilder.Query);
        query[paramName] = paramValue;
        uriBuilder.Query = query.ToString();

        return uriBuilder.Uri;
    }
}

I hope this helps!

You can not test whole abstract class. In this case you have abstract methods, this mean that they should be implemented by class that extend given abstract class.

In that class programmer have to write the source code that is dedicated for logic of his.

In other words there is no sens of testing abstract class because you are not able to check the final behavior of it.

If you have major functionality not related to abstract methods in some abstract class, just create another class where the abstract method will throw some exception.

Try this!

UPDATE for Bootstrap 4 stable

The cursor: pointer; rule has been restored, so buttons will now by default have the cursor on hover:

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css">_x000D_
<button type="button" class="btn btn-success">Sample Button</button>

No, there isn't. You need to make some custom CSS for this.

If you just need a link that looks like a button (with pointer), use this:

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-beta.2/css/bootstrap.min.css">_x000D_
<a class="btn btn-success" href="#" role="button">Sample Button</a>

    $("#select_location_id").val(value);
    $("#select_location_id").select2().trigger('change');

I solved my problem with this simple code. Where #select_location_id is an ID of select box and value is value of an option listed in select2 box.

It's easier with the enumitem package:

\documentclass{article}
\usepackage{enumitem}
\begin{document}
Less space:
\begin{itemize}[noitemsep]
  \item foo
  \item bar
  \item baz
\end{itemize}

Even more compact:
\begin{itemize}[noitemsep,nolistsep]
  \item foo
  \item bar
  \item baz
\end{itemize}
\end{document}

The enumitem package provides a lot of features to customize bullets, numbering and lengths.

The paralist package provides very compact lists: compactitem, compactenum and even lists within paragraphs like inparaenum and inparaitem.

use this function that i've made:

function buildObject($class,$data){
    $object = new $class;
    foreach($data as $key=>$value){
        if(property_exists($class,$key)){
            $object->{'set'.ucfirst($key)}($value);
        }
    }
    return $object;
}

Usage:

$myObject = buildObject('MyClassName',$myArray);

The modern recommendation is to use NSURLs for files and directories instead of NSString based paths:

So to get the Document directory for the app as an NSURL:

func databaseURL() -> NSURL? {

    let fileManager = NSFileManager.defaultManager()

    let urls = fileManager.URLsForDirectory(.DocumentDirectory, inDomains: .UserDomainMask)

    if let documentDirectory: NSURL = urls.first as? NSURL {
        // This is where the database should be in the documents directory
        let finalDatabaseURL = documentDirectory.URLByAppendingPathComponent("items.db")

        if finalDatabaseURL.checkResourceIsReachableAndReturnError(nil) {
            // The file already exists, so just return the URL
            return finalDatabaseURL
        } else {
            // Copy the initial file from the application bundle to the documents directory
            if let bundleURL = NSBundle.mainBundle().URLForResource("items", withExtension: "db") {
                let success = fileManager.copyItemAtURL(bundleURL, toURL: finalDatabaseURL, error: nil)
                if success {
                    return finalDatabaseURL
                } else {
                    println("Couldn't copy file to final location!")
                }
            } else {
                println("Couldn't find initial database in the bundle!")
            }
        }
    } else {
        println("Couldn't get documents directory!")
    }

    return nil
}

This has rudimentary error handling, as that sort of depends on what your application will do in such cases. But this uses file URLs and a more modern api to return the database URL, copying the initial version out of the bundle if it does not already exist, or a nil in case of error.

Use this way so that result will not be displayed while running stored procedure.

The query:

SELECT a.strUserID FROM tblUsers a WHERE a.lngUserID = lngUserID LIMIT 1 INTO @strUserID;

Here is a trick for getting automatic keyboard dismissal behavior with no code at all. In the nib, edit the First Responder proxy object in the Identity inspector, adding a new first responder action; let's call it dummy:. Now hook the Did End on Exit event of the text field to the dummy: action of the First Responder proxy object. That's it! Since the text field's Did End on Exit event now has an action–target pair, the text field automatically dismisses its keyboard when the user taps Return; and since there is no penalty for not finding a handler for a message sent up the responder chain, the app doesn't crash even though there is no implementation of dummy: anywhere.

Try this:

docker run --rm -i --net=host alpine ifconfig

This seems to explain it.

The definition of order is that a[order(a)] is in increasing order. This works with your example, where the correct order is the fourth, second, first, then third element.

You may have been looking for rank, which returns the rank of the elements
R> a <- c(4.1, 3.2, 6.1, 3.1)
R> order(a)
[1] 4 2 1 3
R> rank(a)
[1] 3 2 4 1
so rank tells you what order the numbers are in, order tells you how to get them in ascending order.

plot(a, rank(a)/length(a)) will give a graph of the CDF. To see why order is useful, though, try plot(a, rank(a)/length(a),type="S") which gives a mess, because the data are not in increasing order

If you did
oo<-order(a)
plot(a[oo],rank(a[oo])/length(a),type="S")
or simply
oo<-order(a)
plot(a[oo],(1:length(a))/length(a)),type="S")
you get a line graph of the CDF.

I'll bet you're thinking of rank.

Yes, there is. You can use the Arrays class from the java.util.* package. Then it's actually just one line of code.

List<String> list = Arrays.asList(array);

TL;DR; for Windows users:

(Quotation marks not needed if path has no blank spaces)

Git Bash: cd "/C/Program Files (x86)/Android" // macOS/Linux syntax

Cmd.exe: cd "C:\Program Files (x86)\Android" // windows syntax

When using git bash on windows, you have to:

• remove the colon after the drive letter
• replace your back-slashes with forward-slashes
• If you have blank spaces in your path: Put quotation marks at beginning and end of the path

Git Bash: cd "/C/Program Files (x86)/Android" // macOS/Linux syntax

Cmd.exe: cd "C:\Program Files (x86)\Android" // windows syntax

document.querySelectorAll("[data-foo]")

will get you all elements with that attribute.

document.querySelectorAll("[data-foo='1']")

will only get you ones with a value of 1.

• Lets say 1st component is DbstatsMainComponent
• 2nd component DbstatsGraphComponent.
• 1st component calling the method of 2nd

<button (click)="dbgraph.displayTableGraph()">Graph</button> <dbstats-graph #dbgraph></dbstats-graph>

Note the local variable #dbgraph on the child component, which the parent can use to access its methods (dbgraph.displayTableGraph()).

may be:

UIImage *img = [[UIImage alloc] init];

and when you want to change the image:

img = [UIImage imageNamed:@"nameOfPng.png"];

but the object wasn't in the same place in the memory, but if you use the pointer, the same pointer will be point to the last image loaded.

Using setInterval:

setInterval(function() {
    // your code goes here...
}, 60 * 1000); // 60 * 1000 milsec

The function returns an id you can clear your interval with clearInterval:

var timerID = setInterval(function() {
    // your code goes here...
}, 60 * 1000); 

clearInterval(timerID); // The setInterval it cleared and doesn't run anymore.

A "sister" function is setTimeout/clearTimeout look them up.

If you want to run a function on page init and then 60 seconds after, 120 sec after, ...:

function fn60sec() {
    // runs every 60 sec and runs on init.
}
fn60sec();
setInterval(fn60sec, 60*1000);

Let's fit the model:

> library(ISwR)
> fit <- lm(metabolic.rate ~ body.weight, rmr)
> summary(fit)

Call:
lm(formula = metabolic.rate ~ body.weight, data = rmr)

Residuals:
    Min      1Q  Median      3Q     Max

The 95% confidence interval for the slope is the estimated coefficient (7.0595) ± two standard errors (0.9776).

This can be computed using confint:

> confint(fit, 'body.weight', level=0.95)
               2.5 % 97.5 %
body.weight 5.086656 9.0324

It should be :

public async Task<ActionResult> GetSomeJsonData()
{
    var model = // ... get data or build model etc.

    return Json(new { Data = model }, JsonRequestBehavior.AllowGet); 
}

or more simply:

return Json(model, JsonRequestBehavior.AllowGet); 

I did notice that you are calling GetResources() from another ActionResult which wont work. If you are looking to get JSON back, you should be calling GetResources() from ajax directly...

I came back to this problem now that we are finalizing the game and I just thought to post what worked for me.

This is the method for rotating the Matrix:

this.matrix.reset();
this.matrix.setTranslate(this.floatXpos, this.floatYpos);
this.matrix.postRotate((float)this.direction, this.getCenterX(), this.getCenterY()); 

(this.getCenterX() is basically the bitmaps X position + the bitmaps width / 2)

And the method for Drawing the bitmap (called via a RenderManager Class):

canvas.drawBitmap(this.bitmap, this.matrix, null);

So it is prettey straight forward but I find it abit strange that I couldn't get it to work by setRotate followed by postTranslate. Maybe some knows why this doesn't work? Now all the bitmaps rotate properly but it is not without some minor decrease in bitmap quality :/

Anyways, thanks for your help!

I am linking to what essentially is the same discussion where Peter Lawrey is providing a good answer. Why I get a negative elapsed time using System.nanoTime()?

Many people mentioned that in Java System.nanoTime() could return negative time. I for apologize for repeating what other people already said.

1. nanoTime() is not a clock but CPU cycle counter.
2. Return value is divided by frequency to look like time.
3. CPU frequency may fluctuate.
4. When your thread is scheduled on another CPU, there is a chance of getting nanoTime() which results in a negative difference. That's logical. Counters across CPUs are not synchronized.
5. In many cases, you could get quite misleading results but you wouldn't be able to tell because delta is not negative. Think about it.
6. (unconfirmed) I think you may get a negative result even on the same CPU if instructions are reordered. To prevent that, you'd have to invoke a memory barrier serializing your instructions.

It'd be cool if System.nanoTime() returned coreID where it executed.

To initialize layers you typically don't need to do anything.

PyTorch will do it for you. If you think about, this has lot of sense. Why should we initialize layers, when PyTorch can do that following the latest trends.

Check for instance the Linear layer.

In the __init__ method it will call Kaiming He init function.

    def reset_parameters(self):
        init.kaiming_uniform_(self.weight, a=math.sqrt(3))
        if self.bias is not None:
            fan_in, _ = init._calculate_fan_in_and_fan_out(self.weight)
            bound = 1 / math.sqrt(fan_in)
            init.uniform_(self.bias, -bound, bound)

The similar is for other layers types. For conv2d for instance check here.

To note : The gain of proper initialization is the faster training speed. If your problem deserves special initialization you can do it afterwords.

TL;DR:

No, don't subscribe manually to them, don't use them in services. Use them as is shown in the documentation only to emit events in components. Don't defeat angular's abstraction.

Answer:

No, you should not subscribe manually to it.

EventEmitter is an angular2 abstraction and its only purpose is to emit events in components. Quoting a comment from Rob Wormald

[...] EventEmitter is really an Angular abstraction, and should be used pretty much only for emitting custom Events in components. Otherwise, just use Rx as if it was any other library.

This is stated really clear in EventEmitter's documentation.

Use by directives and components to emit custom Events.

What's wrong about using it?

Angular2 will never guarantee us that EventEmitter will continue being an Observable. So that means refactoring our code if it changes. The only API we must access is its emit() method. We should never subscribe manually to an EventEmitter.

All the stated above is more clear in this Ward Bell's comment (recommended to read the article, and the answer to that comment). Quoting for reference

Do NOT count on EventEmitter continuing to be an Observable!

Do NOT count on those Observable operators being there in the future!

These will be deprecated soon and probably removed before release.

Use EventEmitter only for event binding between a child and parent component. Do not subscribe to it. Do not call any of those methods. Only call eve.emit()

His comment is in line with Rob's comment long time ago.

So, how to use it properly?

Simply use it to emit events from your component. Take a look a the following example.

@Component({
    selector : 'child',
    template : `
        <button (click)="sendNotification()">Notify my parent!</button>
    `
})
class Child {
    @Output() notifyParent: EventEmitter<any> = new EventEmitter();
    sendNotification() {
        this.notifyParent.emit('Some value to send to the parent');
    }
}

@Component({
    selector : 'parent',
    template : `
        <child (notifyParent)="getNotification($event)"></child>
    `
})
class Parent {
    getNotification(evt) {
        // Do something with the notification (evt) sent by the child!
    }
}

How not to use it?

class MyService {
    @Output() myServiceEvent : EventEmitter<any> = new EventEmitter();
}

Stop right there... you're already wrong...

Hopefully these two simple examples will clarify EventEmitter's proper usage.

I'd agree with some of the others out there saying that NetBeans and IntelliJ are both good IDEs. And I'd say that in using all three (Eclipse + other two), that Eclipse is by far my favorite. I found some of the documentation out-dated, but also found the support community very helpful. I started using Eclipse by jumping into the deep end of the pool: writing an RCP before ever learning the IDE. The IDE was intuitive to use, and when I found the right news groups to post to - most of my questions were already answered. The hardest thing for me (and frustrating, admittedly) was knowing how to phrase my search terms in order to get to the answer that was already posted.

Remember that Eclipse is still "relatively new" as an IDE player, though given that - it's pretty darn robust.

My only complaint about Eclipse is that with each new release, it seems to hog up more resources. With a mid-sized project/workspace, it takes seemingly forever to build (or rebuild) the project. Compared to IntelliJ, it's faster and more intuitive to use.

public class AssemblyLoader<T>  where T:class
{
    public void(){
        var res = Load(@"C:\test\paquete.uno.dos.test.dll", "paquete.uno.dos.clasetest.dll") 
    }

    public T Load(string assemblyFile, string objectToInstantiate) 
    {
        var loaded = Activator.CreateInstanceFrom(assemblyFile, objectToInstantiate).Unwrap();

        return loaded as T;
    }
}

If you don't want to add LINQ or other extensions just do:

float[] subArray = new List<float>(myArray).GetRange(0, 8).ToArray();

<th nowrap="nowrap">

or

<th style="white-space:nowrap;">

or

<th class="nowrap">
<style type="text/css">
.nowrap { white-space: nowrap; }
</style>

Easy removing leading, trailing and extra spaces from a std::string in one line

value = std::regex_replace(value, std::regex("^ +| +$|( ) +"), "$1");

removing only leading spaces

value.erase(value.begin(), std::find_if(value.begin(), value.end(), std::bind1st(std::not_equal_to<char>(), ' ')));

or

value = std::regex_replace(value, std::regex("^ +"), "");

removing only trailing spaces

value.erase(std::find_if(value.rbegin(), value.rend(), std::bind1st(std::not_equal_to<char>(), ' ')).base(), value.end());

or

value = std::regex_replace(value, std::regex(" +$"), "");

removing only extra spaces

value = regex_replace(value, std::regex(" +"), " ");

MySQL manual says:

When reading data with LOAD DATA INFILE, empty or missing columns are updated with ''. If you want a NULL value in a column, you should use \N in the data file. The literal word “NULL” may also be used under some circumstances.

So you need to replace the blanks with \N like this:

1,2,3,4,5
1,2,3,\N,5
1,2,3

Use JavaScript (screen.width and screen.height IIRC, but I may be wrong, haven't done JS in a while). PHP cannot do it.

Instead of using any setTimeout or setInterval I would stick to deferred objects (implementation by jQuery here). It's still tricky to resolve queue in proper moment, because init don't have callbacks but combining result with event subscription (as someone pointed before me), should do the trick and be close enough.

Pseudo-snippet would look as follows:

FB.Event.subscribe('auth.statusChange', function(response) {
   if (response.authResponse) {
       // user has auth'd your app and is logged into Facebook
   } else {
       // user has not auth'd your app, or is not logged into Facebook
   }
   DeferredObject.resolve();
});

After searching stackoverflow and the web a lot, I've got to conclution that the best way of doing it is like this:

- (BOOL)isEndDateIsSmallerThanCurrent:(NSDate *)checkEndDate
{
    NSDate* enddate = checkEndDate;
    NSDate* currentdate = [NSDate date];
    NSTimeInterval distanceBetweenDates = [enddate timeIntervalSinceDate:currentdate];
    double secondsInMinute = 60;
    NSInteger secondsBetweenDates = distanceBetweenDates / secondsInMinute;

    if (secondsBetweenDates == 0)
        return YES;
    else if (secondsBetweenDates < 0)
        return YES;
    else
        return NO;
}

You can change it to difference between hours also.

Enjoy!

Edit 1

If you want to compare date with format of dd/MM/yyyy only, you need to add below lines between NSDate* currentdate = [NSDate date]; && NSTimeInterval distance

NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"dd/MM/yyyy"];
[dateFormatter setLocale:[[[NSLocale alloc] initWithLocaleIdentifier:@"en_US"]
                          autorelease]];

NSString *stringDate = [dateFormatter stringFromDate:[NSDate date]];

currentdate = [dateFormatter dateFromString:stringDate];

After painful experimentation to find something faster than the accepted answer, I got this to work. It ran around 100x faster on the dataset I tried it on.

If someone knows a way to make this more elegant, by all means please modify my code. I couldn't find a way that works without setting the other columns you want to keep as the index and then resetting the index and re-naming the columns, but I'd imagine there's something else that works.

b = DataFrame(a.var1.str.split(',').tolist(), index=a.var2).stack()
b = b.reset_index()[[0, 'var2']] # var1 variable is currently labeled 0
b.columns = ['var1', 'var2'] # renaming var1

In my case, I was getting this error because I had an input named x and I was creating (without realizing it) a local variable called x. I thought I was trying to access an element of the input x (which was an array), while I was actually trying to access an element of the local variable x (which was a scalar).

Answer in kotlin:

  context?.let {
        val displayMetrics = it.resources.displayMetrics
        val dpHeight = displayMetrics.heightPixels / displayMetrics.density
        val dpWidth = displayMetrics.widthPixels / displayMetrics.density
    }

I think, the differences between ArrayList and List<T> are:

1. List<T>, where T is value-type is faster than ArrayList. This is because List<T> avoids boxing/unboxing (where T is value-type).
2. Many sources say - usually ArrayList used just for backward compatibility. (is not a real difference, but i think it is important note).
3. Reflection is easier with nongeneric ArrayList then List<T>

4. ArrayList has IsSynchronized property. So, It is easy to create and use syncronised ArrayList. I didin't found IsSynchronized property for List<T>. Also Keep in mind this type of synchronization is relatively inefficient, msdn):

   var arraylist = new ArrayList();
   var arrayListSyncronized = ArrayList.Synchronized(arraylist
   Console.WriteLine($"syncronized {arraylist.IsSynchronized}");
   Console.WriteLine($"syncronized {arrayListSyncronized.IsSynchronized}");
   
   var list = new List<object>();
   var listSyncronized = ArrayList.Synchronized(list);
   Console.WriteLine($"syncronized {list.IsSynchronized}");//error, no such prop
   Console.WriteLine($"syncronized {list.IsSynchronized}");//error, no such prop
   

5. ArrayList has ArrayList.SyncRoot property which can be used for syncronisation (msdn). List<T> hasn't SyncRoot property, so in the following construction you need to use some object if you use List<T>:

   ArrayList myCollection = new ArrayList();
   lock(myCollection.SyncRoot) //  ofcourse you can use another object for this goal
   {
       foreach (object item in myCollection)
       {
           // ...
       }
   }
   

Since AngularJS does not have directive DOM manipulations as jQuery does, a proper way to modify attributes of one element will be using directive. Through link function of a directive, you have access to both element and its attributes.

Wrapping you whole input inside one directive, you can still introduce ng-model's methods through controller property.

This method will help to decouple the logic of ngmodel with placeholder from controller. If there is no logic between them, you can definitely go as Wagner Francisco said.

Why don't you just put a hijacked onClick() event handler that will fire only when JS is enabled, and use this to append a parameter (js=true) to the clicked/selected URL (you could also detect a drop down list and change the value- of add a hidden form field). So now when the server sees this parameter (js=true) it knows that JS is enabled and then do your fancy logic server-side.
The down side to this is that the first time a users comes to your site, bookmark, URL, search engine generated URL- you will need to detect that this is a new user so don't look for the NVP appended into the URL, and the server would have to wait for the next click to determine the user is JS enabled/disabled. Also, another downside is that the URL will end up on the browser URL and if this user then bookmarks this URL it will have the js=true NVP, even if the user does not have JS enabled, though on the next click the server would be wise to knowing whether the user still had JS enabled or not. Sigh.. this is fun...

Just to add another example in terms of mobile app development. In iOS and Android, we have Interface Builders, where we can define UI of the apps.

The UI drawn using these Builders is declarative in nature, where we drag and drop the components. The actual drawing happens underneath and performed by the framework and system.

But we can also draw the whole components in code, and that is imperative in nature.

Also, some new languages like Angular JS are focussing on designing UIs declaratively and we may see a lot of other languages offering the same support. Like Java doesn't have any good declarative way to draw native desktop apps in Java swing or Java FX but in the near future, they just might.

Even after 5 years, and having some experience with idea, I still have this problem all the times. Here is the simplest solution.

• Close Idea
• Delete .idea
• Start Idea and open project instead of import project

And then, open conf file for your framework, like pom.xml or build.sbt or build.gradle etc and it will automatically prompts to import project and when you click and when it finishes, your project is mostly setup correct.

Since I've already been where you are right now, I think I can "answer" you.

The fact is there is no easy way to make a GUI. GUI's are highly dependent on platform and OS specific code, that's why you should start reading your target platform/OS documentation on window management APIs. The good thing is: there are plenty of libraries that address these limitations and abstract architecture differences into a single multi-platform API. Those suggested before, GTK and Qt, are some of these libraries.

But even these are a little too complicated, since lots of new concepts, data types, namespaces and classes are introduced, all at once. For this reason, they use to come bundled with some GUI WYSIWYG editor. They pretty much make programming software with GUIs possible.

To sum it up, there are also non free "environments" for GUI development such as Visual Studio from Microsoft. For those with Delphi experience backgrounds, Visual Studio may be more familiar. There are also free alternatives to the full Visual Studio environment supplied from Microsoft: Visual Studio Express, which is more than enough for starting on GUI development.

You can also user java Regular Expression. String.split() also uses the expression internally. Refer http://download.oracle.com/javase/1.4.2/docs/api/java/util/regex/Pattern.html

True, there is no vivid and unambiguous way to declare a single-value variable, what you can do is

with myVar as (select "any value really")

then, to get access to the value stored in this construction, you do

(select * from myVar)

for example

with var as (select 123)    
... where id = (select * from var)

This can also be done using Hadley's plyr package, and the rename function.

library(plyr) 
df <- data.frame(foo=rnorm(1000)) 
df <- rename(df,c('foo'='samples'))

You can rename by the name (without knowing the position) and perform multiple renames at once. After doing a merge, for example, you might end up with:

  letterid id.x id.y
1       70    2    1
2      116    6    5
3      116    6    4
4      116    6    3
5      766   14    9
6      766   14   13

Which you can then rename in one step using:

letters <- rename(letters,c("id.x" = "source", "id.y" = "target"))

  letterid source target
1       70      2      1
2      116      6      5
3      116      6      4
4      116      6      3
5      766     14      9
6      766     14     13

<form id="myForm">
<select id="selectNumber">
    <option>Choose a number</option>
    <script>
        var myArray = new Array("1", "2", "3", "4", "5" . . . . . "N");
        for(i=0; i<myArray.length; i++) {  
            document.write('<option value="' + myArray[i] +'">' + myArray[i] + '</option>');
        }
    </script>
</select>
</form>

This sounds weird and I don't know why, but in my case that was happening because my ConnectionString was using "." in "data source" attribute. Once I changed it to "localhost" it workded like a charm. No other change was needed.

Just for the sake of understanding of others who may not get the whole picture clear following code works for me to find a field and then update it

ObjectMapper mapper = new ObjectMapper();
JsonNode rootNode = mapper.readTree(JsonString);    
JsonPointer valueNodePointer = JsonPointer.compile("/GrandObj/Obj/field");
JsonPointer containerPointer = valueNodePointer.head();
JsonNode parentJsonNode = rootNode.at(containerPointer);

if (!parentJsonNode.isMissingNode() && parentJsonNode.isObject()) {
    ObjectNode parentObjectNode = (ObjectNode) parentJsonNode;
    //following will give you just the field name. 
    //e.g. if pointer is /grandObject/Object/field
    //JsonPoint.last() will give you /field 
    //remember to take out the / character 
    String fieldName = valueNodePointer.last().toString();
    fieldName = fieldName.replace(Character.toString(JsonPointer.SEPARATOR), StringUtils.EMPTY);
    JsonNode fieldValueNode = parentObjectNode.get(fieldName);

    if(fieldValueNode != null) {
        parentObjectNode.put(fieldName, "NewValue");
    }
}

in build.gradle add Guava

    compile group: 'com.google.guava', name: 'guava', version: '27.0-jre'

and then

    public static List<String> splitByComma(String str) {
    Iterable<String> split = Splitter.on(",")
            .omitEmptyStrings()
            .trimResults()
            .split(str);
    return Lists.newArrayList(split);
    }

    public static String joinWithComma(Set<String> words) {
        return Joiner.on(", ").skipNulls().join(words);
    }

enjoy :)

My recipe of symmetric difference between two dictionaries:

def find_dict_diffs(dict1, dict2):
    unequal_keys = []
    unequal_keys.extend(set(dict1.keys()).symmetric_difference(set(dict2.keys())))
    for k in dict1.keys():
        if dict1.get(k, 'N\A') != dict2.get(k, 'N\A'):
            unequal_keys.append(k)
    if unequal_keys:
        print 'param', 'dict1\t', 'dict2'
        for k in set(unequal_keys):
            print str(k)+'\t'+dict1.get(k, 'N\A')+'\t '+dict2.get(k, 'N\A')
    else:
        print 'Dicts are equal'

dict1 = {1:'a', 2:'b', 3:'c', 4:'d', 5:'e'}
dict2 = {1:'b', 2:'a', 3:'c', 4:'d', 6:'f'}

find_dict_diffs(dict1, dict2)

And result is:

param   dict1   dict2
1       a       b
2       b       a
5       e       N\A
6       N\A     f

What happens is that apache is being run as the user "_www" and doesn't have permissions to edit any files. You'll notice NO filesystem functions work via php.

How to fix:

Open a finder window and from the menu bar, choose Go > Go To Folder > /private/etc/apache2

now open httpd.conf

find:

User _www 
Group _www

change the username:

User <YOUR LOGIN USERNAME>

Now restart apache by running this form terminal:

sudo apachectl -k restart

If it still doesn't work, I happen to do the following before I did the above. Could be related.

Open terminal and run the following commands: (note, my webserver files are located at /Library/WebServer/www. Change according to your website location)

sudo chmod 775 /Library/WebServer/www

Maybe, as in my silly situation, you may somehow created the ssh key by directly typing

ssh-keygen

And so it is created with the local system user credentials so they don't match, use full command like this and recreate

ssh-keygen -t rsa -b 4096 -C "[email protected]"

I recently faced the same issue.

The reason behind this issue is that the activity being closed before the dialog is dismissed. There are various reasons for the above to happen. The ones mentioned in the posts above are also correct.

I got into a situation, because in the thread, I was calling a function which was throwing exception. Because of which the window was being dismissed and hence the exception.

In your script you can add the following to the lines that you know are going to give an output:

some_code 2>>/dev/null

Or else you can also try

some_code >>/dev/null

I was solving this leetcode problem and I came across this beautiful solution by a user named Zitao Wang.

The problem goes like this for each element in the given array find the product of all the remaining numbers without making use of divison and in O(n) time

The standard solution is:

Pass 1: For all elements compute product of all the elements to the left of it
Pass 2: For all elements compute product of all the elements to the right of it
        and then multiplying them for the final answer 

His solution uses only one for loop by making use of. He computes the left product and right product on the fly using ~

def productExceptSelf(self, nums):
    res = [1]*len(nums)
    lprod = 1
    rprod = 1
    for i in range(len(nums)):
        res[i] *= lprod
        lprod *= nums[i]
        res[~i] *= rprod
        rprod *= nums[~i]
    return res

In addition to the extensions which are maintained and provided by the core PostgreSQL development team, there are extensions available from third parties. Notably, there is a site dedicated to that purpose: http://www.pgxn.org/

When the user enters his/her username, check for valid entry also.

java.util.Scanner input = new java.util.Scanner(System.in);
String userName;
final int validLength = 6; // This is the valid length of an user name

System.out.print("Please enter the username: ");
userName = input.nextLine();

while(userName.length() < validLength) {

    // If the user enters less than validLength characters
    // ask for entering again
    System.out.println(
        "\nUsername needs to be " + validLength + " character long");

    System.out.print("\nPlease enter the username again: ");
    userName = input.nextLine();
}

System.out.println("Username is: " + userName);

import * as Rx from 'rxjs/Rx';

We should add the above import to make the blow code to work

Let obs = Rx.Observable
    .interval(1000).take(3);

obs.subscribe(value => console.log('Subscriber: ' + value));

Extending @jmvtrinidad solution for Angular,

When working with a already existing typed object, this is how to add new property.

let user: User = new User();
(user as any).otherProperty = 'hello';
//user did not lose its type here.

Now if you want to use otherProperty in html side, this is what you'd need:

<div *ngIf="$any(user).otherProperty">
   ...
   ...
</div>

Angular compiler treats $any() as a cast to the any type just like in TypeScript when a <any> or as any cast is used.

The rowSums function (as Greg mentions) will do what you want, but you are mixing subsetting techniques in your answer, do not use "$" when using "[]", your code should look something more like:

data$new <- rowSums( data[,43:167] )

If you want to use a function other than sum, then look at ?apply for applying general functions accross rows or columns.

if var sum=0; var x;

then, what about this? sum+=(x|0);

Understand does a very good job of creating call graphs.

karim79's get_headers() solution didn't worked for me as I gotten crazy results with Pinterest.

get_headers(): SSL operation failed with code 1. OpenSSL Error messages: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed

Array
(
    [url] => https://www.pinterest.com/jonathan_parl/
    [exists] => 
)

get_headers(): Failed to enable crypto

Array
(
    [url] => https://www.pinterest.com/jonathan_parl/
    [exists] => 
)

get_headers(https://www.pinterest.com/jonathan_parl/): failed to open stream: operation failed

Array
(
    [url] => https://www.pinterest.com/jonathan_parl/
    [exists] => 
) 

Anyway, this developer demonstrates that cURL is way faster than get_headers():

http://php.net/manual/fr/function.get-headers.php#104723

Since many people asked for karim79 to fix is cURL solution, here's the solution I built today.

/**
* Send an HTTP request to a the $url and check the header posted back.
*
* @param $url String url to which we must send the request.
* @param $failCodeList Int array list of code for which the page is considered invalid.
*
* @return Boolean
*/
public static function isUrlExists($url, array $failCodeList = array(404)){

    $exists = false;

    if(!StringManager::stringStartWith($url, "http") and !StringManager::stringStartWith($url, "ftp")){

        $url = "https://" . $url;
    }

    if (preg_match(RegularExpression::URL, $url)){

        $handle = curl_init($url);


        curl_setopt($handle, CURLOPT_RETURNTRANSFER, true);

        curl_setopt($handle, CURLOPT_SSL_VERIFYPEER, false);

        curl_setopt($handle, CURLOPT_HEADER, true);

        curl_setopt($handle, CURLOPT_NOBODY, true);

        curl_setopt($handle, CURLOPT_USERAGENT, true);


        $headers = curl_exec($handle);

        curl_close($handle);


        if (empty($failCodeList) or !is_array($failCodeList)){

            $failCodeList = array(404); 
        }

        if (!empty($headers)){

            $exists = true;

            $headers = explode(PHP_EOL, $headers);

            foreach($failCodeList as $code){

                if (is_numeric($code) and strpos($headers[0], strval($code)) !== false){

                    $exists = false;

                    break;  
                }
            }
        }
    }

    return $exists;
}

Let me explains the curl options:

CURLOPT_RETURNTRANSFER: return a string instead of displaying the calling page on the screen.

CURLOPT_SSL_VERIFYPEER: cUrl won't checkout the certificate

CURLOPT_HEADER: include the header in the string

CURLOPT_NOBODY: don't include the body in the string

CURLOPT_USERAGENT: some site needs that to function properly (by example : https://plus.google.com)

Additional note: In this function I'm using Diego Perini's regex for validating the URL before sending the request:

const URL = "%^(?:(?:https?|ftp)://)(?:\S+(?::\S*)?@|\d{1,3}(?:\.\d{1,3}){3}|(?:(?:[a-z\d\x{00a1}-\x{ffff}]+-?)*[a-z\d\x{00a1}-\x{ffff}]+)(?:\.(?:[a-z\d\x{00a1}-\x{ffff}]+-?)*[a-z\d\x{00a1}-\x{ffff}]+)*(?:\.[a-z\x{00a1}-\x{ffff}]{2,6}))(?::\d+)?(?:[^\s]*)?$%iu"; //@copyright Diego Perini

Additional note 2: I explode the header string and user headers[0] to be sure to only validate only the return code and message (example: 200, 404, 405, etc.)

Additional note 3: Sometime validating only the code 404 is not enough (see the unit test), so there's an optional $failCodeList parameter to supply all the code list to reject.

And, of course, here's the unit test (including all the popular social network) to legitimates my coding:

public function testIsUrlExists(){

//invalid

Lots of good answers already. I personally go with awk. For convenience, if you use bash, just add the below to your ~/.bash_profile. And, the next time you log in (or if you source your .bash_profile after this update), you will have a new nifty "nth" function available to pipe your files through.

Execute this or put it in your ~/.bash_profile (if using bash) and reopen bash (or execute source ~/.bach_profile)

# print just the nth piped in line
nth () { awk -vlnum=${1} 'NR==lnum {print; exit}'; } 

Then, to use it, simply pipe through it. E.g.,:

$ yes line | cat -n | nth 5
     5  line

Setting the JAVA_HOME, CATALINA_HOME Environment Variable on Windows

One can do using command prompt:

1. set JAVA_HOME=C:\ "top level directory of your java install"
2. set CATALINA_HOME=C:\ "top level directory of your Tomcat install"
3. set PATH=%PATH%;%JAVA_HOME%\bin;%CATALINA_HOME%\bin

OR you can do the same:

1. Go to system properties
2. Go to environment variables and add a new variable with the name JAVA_HOME and provide variable value as C:\ "top level directory of your java install"
3. Go to environment variables and add a new variable with the name CATALINA_HOME and provide variable value as C:\ "top level directory of your Tomcat install"
4. In path variable add a new variable value as ;%CATALINA_HOME%\bin;

It can be very useful when flattening a hierarchy and/or mapping objects. Instead of:

if (Model.Model2 == null
  || Model.Model2.Model3 == null
  || Model.Model2.Model3.Model4 == null
  || Model.Model2.Model3.Model4.Name == null)
{
  mapped.Name = "N/A"
}
else
{
  mapped.Name = Model.Model2.Model3.Model4.Name;
}

It can be written like (same logic as above)

mapped.Name = Model.Model2?.Model3?.Model4?.Name ?? "N/A";

DotNetFiddle.Net Working Example.

(the ?? or null-coalescing operator is different than the ? or null conditional operator).

It can also be used out side of assignment operators with Action. Instead of

Action<TValue> myAction = null;

if (myAction != null)
{
  myAction(TValue);
}

It can be simplified to:

myAction?.Invoke(TValue);

DotNetFiddle Example:

using System;

public class Program
{
  public static void Main()
  {
    Action<string> consoleWrite = null;

    consoleWrite?.Invoke("Test 1");

    consoleWrite = (s) => Console.WriteLine(s);

    consoleWrite?.Invoke("Test 2");
  }
}

Result:

Test 2

The easiest way is to hard code the columns yourself to better control the output file:

SELECT 'ColName1', 'ColName2', 'ColName3'
UNION ALL
SELECT ColName1, ColName2, ColName3
    FROM YourTable
    INTO OUTFILE '/path/outfile'

You can do:

<hr style="border: 1px dashed black;" />

You can't change CSS properties directly with jQuery. But you can achieve the same effect in at least two ways.

Dynamically Load CSS from a File

function updateStyleSheet(filename) {
    newstylesheet = "style_" + filename + ".css";

    if ($("#dynamic_css").length == 0) {
        $("head").append("<link>")
        css = $("head").children(":last");

        css.attr({
          id: "dynamic_css",
          rel:  "stylesheet",
          type: "text/css",
          href: newstylesheet
        });
    } else {
        $("#dynamic_css").attr("href",newstylesheet);
    }
}

The example above is copied from:

• How To Switch CSS Files On-The-Fly Using jQuery

Dynamically Add a Style Element

$("head").append('<style type="text/css"></style>');
var newStyleElement = $("head").children(':last');
newStyleElement.html('.red{background:green;}');

The example code is copied from this JSFiddle fiddle originally referenced by Alvaro in their comment.

In the Latest Android Studio 3.1.3, Dependency:

or

Even in latest by 27th of Aug 18 ie

implementation 'com.android.support:appcompat-v7:28.0.0-rc01' facing similar issue

Change it to

    implementation 'com.android.support:appcompat-v7:28.0.0-alpha1

This will solve your problem of Preview.

UPDATE

Still, in beta01 there is a preview problem for latest appcompact v7 library make the above change as changing it to alpha01 for solving rendering problem

Replace each loop with any closure.

def list = [1, 2, 3, 4, 5]
list.any { element ->

        return // continue

    println element

    if (element == 3)
        return true // break

Re: Same navbar on multiple pages Aug 21, 2018 10:13 AM|LINK

As far as I know, there are multiple solution.

For example:

The Entire code for navigation bar is in nav.html file (without any html or body tag, only the code for navigation bar).

Then we could directly load it from the jquery without writing a lot of codes.

Like this:

    <!--Navigation bar-->
    <div id="nav-placeholder">

    </div>

    <script>
    $(function(){
      $("#nav-placeholder").load("nav.html");
    });
    </script>
    <!--end of Navigation bar-->

Solution2:

You could use JavaScript code to generate the whole nav bar.

Like this:

Javascript code:

$(function () {
    var bar = '';
    bar += '<nav class="navbar navbar-default" role="navigation">';
    bar += '<div class="container-fluid">';
    bar += '<div>';
    bar += '<ul class="nav navbar-nav">';
    bar += '<li id="home"><a href="home.html">Home</a></li>';
    bar += '<li id="index"><a href="index.html">Index</a></li>';
    bar += '<li id="about"><a href="about.html">About</a></li>';
    bar += '</ul>';
    bar += '</div>';
    bar += '</div>';
    bar += '</nav>';

    $("#main-bar").html(bar);

    var id = getValueByName("id");
    $("#" + id).addClass("active");
});

function getValueByName(name) {
    var url = document.getElementById('nav-bar').getAttribute('src');
    var param = new Array();
    if (url.indexOf("?") != -1) {
        var source = url.split("?")[1];
        items = source.split("&");
        for (var i = 0; i < items.length; i++) {
            var item = items[i];
            var parameters = item.split("=");
            if (parameters[0] == "id") {
                return parameters[1];
            }
        }
    }
}

You can use replace_entities from w3lib.html library

Here is the way I executed the program without environment variable configured.

Java file execution procedure: After you saved a file MyFirstJavaProgram.java

Enter the whole Path of "Javac" followed by java file For executing output Path of followed by comment <-cp> followed by followed by

Given below is the example of execution

C:\Program Files\Java\jdk1.8.0_101\bin>javac C:\Sample\MyFirstJavaProgram2.java C:\Program Files\Java\jdk1.8.0_101\bin>java -cp C:\Sample MyFirstJavaProgram2 Hello World

Sometimes, especially when you work with VB, you can miss obvious solutions. Like I was doing last 2 days.

the code, which generates error needs to be moved to a separate function. And in the beginning of the function you write On Error Resume Next. This is how an error can be "swallowed", without swallowing any other errors. Dividing code into small separate functions also improves readability, refactoring & makes it easier to add some new functionality.

Note: This solution is old. Please refer to https://facebook.github.io/react-native/docs/images.html#background-image-via-nesting instead

Try this solution. It is officially supported. I have just tested it and works flawlessly.

var styles = StyleSheet.create({
  backgroundImage: {
    flex: 1,
    alignSelf: 'stretch',
    width: null,
  }
});

And as for using it as Background image, just do the following.

<Image style={styles.backgroundImage}>
  <View>
    <Text>All your stuff</Text>
  </View>
</Image>

The Set statement is only used for object variables (like Range, Cell or Worksheet in Excel), while the simple equal sign '=' is used for elementary datatypes like Integer. You can find a good explanation for when to use set here.

The other problem is, that your variable g1val isn't actually declared as Integer, but has the type Variant. This is because the Dim statement doesn't work the way you would expect it, here (see example below). The variable has to be followed by its type right away, otherwise its type will default to Variant. You can only shorten your Dim statement this way:

Dim intColumn As Integer, intRow As Integer  'This creates two integers

For this reason, you will see the "Empty" instead of the expected "0" in the Watches window.

Try this example to understand the difference:

Sub Dimming()

  Dim thisBecomesVariant, thisIsAnInteger As Integer
  Dim integerOne As Integer, integerTwo As Integer

  MsgBox TypeName(thisBecomesVariant)  'Will display "Empty"
  MsgBox TypeName(thisIsAnInteger )  'Will display "Integer"
  MsgBox TypeName(integerOne )  'Will display "Integer"
  MsgBox TypeName(integerTwo )  'Will display "Integer"

  'By assigning an Integer value to a Variant it becomes Integer, too
  thisBecomesVariant = 0
  MsgBox TypeName(thisBecomesVariant)  'Will display "Integer"

End Sub

Two further notices on your code:

First remark: Instead of writing

'If g1val is bigger than the value in the current cell
If g1val > Cells(33, i).Value Then
  g1val = g1val   'Don't change g1val
Else
  g1val = Cells(33, i).Value  'Otherwise set g1val to the cell's value
End If

you could simply write

'If g1val is smaller or equal than the value in the current cell
If g1val <= Cells(33, i).Value Then
  g1val = Cells(33, i).Value  'Set g1val to the cell's value 
End If

Since you don't want to change g1val in the other case.

Second remark: I encourage you to use Option Explicit when programming, to prevent typos in your program. You will then have to declare all variables and the compiler will give you a warning if a variable is unknown.

Are you missing a function declaration?

void ac_search(uint num_patterns, uint pattern_length, const char *patterns, 
               uint num_records, uint record_length, const char *records, int *matches, Node* trie);

Add it just before your implementation of ac_benchmark_search.

Also set ${COMMAND} to g++ on Linux

Under:

• Project
• Properties
• C/C++ General
• Preprocessor Include Paths, Macros, etc.
• Providers
• CDT GCC Built-in Compiler Settings
• Command to get compiler specs

Replace:

${COMMAND} ${FLAGS} -E -P -v -dD "${INPUTS}"

with:

g++ -std=c++11 -E -P -v -dD "${INPUTS}"

If you don't do this, the Eclipse stdout shows:

Unable to find full path for "-E"

and logs under ${HOME}/eclipse-workspace/.metadata/.log show:

!ENTRY org.eclipse.cdt.core 4 0 2020-04-23 20:17:07.288
!MESSAGE Error: Cannot run program "-E": Unknown reason

because ${COMMAND} ${FLAGS} are empty, and so Eclipse tries to execute the -E that comes next.

I wonder if we can properly define the COMMAND and FLAGS variables on the settings, but I tried to add them as build variables and it didn't work.

In WPF MVVM terms, a POCO class is one that does not Fire PropertyChanged events

    function isset(string, context) {
        try {
            var arr = string.split('.');
            var checkObj = context || window;

            for (var i in arr) {
                if (checkObj[arr[i]] === undefined) return false;

            return true;
        } catch (e) {
            return false;
        }
    }

To use the array type properly as a function argument or template parameter, make a struct instead of a typedef, then add an operator[] to the struct so you can keep the array like functionality like so:

typedef struct type24 {
  char& operator[](int i) { return byte[i]; }
  char byte[3];
} type24;

type24 x;
x[2] = 'r';
char c = x[2];

Avoid sqlite3_clear_bindings(stmt).

The code in the test sets the bindings every time through which should be enough.

The C API intro from the SQLite docs says:

Prior to calling sqlite3_step() for the first time or immediately after sqlite3_reset(), the application can invoke the sqlite3_bind() interfaces to attach values to the parameters. Each call to sqlite3_bind() overrides prior bindings on the same parameter

There is nothing in the docs for sqlite3_clear_bindings saying you must call it in addition to simply setting the bindings.

More detail: Avoid_sqlite3_clear_bindings()

this is js1568's solution, modified to work on a generic array of objects, like:

 var genericObject=[
        {genProp:'this is a string',randomInt:10,isBoolean:false},
        {genProp:'this is another string',randomInt:20,isBoolean:false},
        {genProp:'this is a string',randomInt:10,isBoolean:true},
        {genProp:'this is another string',randomInt:30,isBoolean:false},
        {genProp:'this is a string',randomInt:40,isBoolean:true},
        {genProp:'i like strings',randomInt:60,isBoolean:true},
        {genProp:'this is a string',randomInt:70,isBoolean:true},
        {genProp:'this string is unique',randomInt:50,isBoolean:true},
        {genProp:'this is a string',randomInt:50,isBoolean:false},
        {genProp:'i like strings',randomInt:70,isBoolean:false}
    ]

It accepts one more parameter called propertyName, guess! :)

  $.extend({
        distinctObj:function(obj,propertyName) {
            var result = [];
            $.each(obj,function(i,v){
                var prop=eval("v."+propertyName);
                if ($.inArray(prop, result) == -1) result.push(prop);
            });
            return result;
        }
    });

so, if you need to extract a list of unique values for a given property, for example the values used for randomInt property, use this:

$.distinctObj(genericObject,'genProp');

it returns an array like this:

["this is a string", "this is another string", "i like strings", "this string is unique"] 

Here's some Unicode-friendly ones you can make if you pull in ICU4j. I guess "ignore case" is questionable for the method names because although primary strength comparisons do ignore case, it's described as the specifics being locale-dependent. But it's hopefully locale-dependent in a way the user would expect.

public static boolean containsIgnoreCase(String haystack, String needle) {
    return indexOfIgnoreCase(haystack, needle) >= 0;
}

public static int indexOfIgnoreCase(String haystack, String needle) {
    StringSearch stringSearch = new StringSearch(needle, haystack);
    stringSearch.getCollator().setStrength(Collator.PRIMARY);
    return stringSearch.first();
}

Configure The "php.ini" File

First, ensure that PHP is configured to allow file uploads. In your "php.ini" file, search for the file_uploads directive, and set it to On:

file_uploads = On 

Create The HTML Form

Next, create an HTML form that allow users to choose the image file they want to upload:

<!DOCTYPE html>
<html>
<body>

<form action="upload.php" method="post" enctype="multipart/form-data">
    Select image to upload:
    <input type="file" name="fileToUpload" id="fileToUpload">
    <input type="submit" value="Upload Image" name="submit">
</form>

</body>
</html>

Some rules to follow for the HTML form above: Make sure that the form uses method="post" The form also needs the following attribute: enctype="multipart/form-data". It specifies which content-type to use when submitting the form Without the requirements above, the file upload will not work. Other things to notice: The type="file" attribute of the tag shows the input field as a file-select control, with a "Browse" button next to the input control The form above sends data to a file called "upload.php", which we will create next.

Create The Upload File PHP Script

The "upload.php" file contains the code for uploading a file:

<?php
$target_dir = "uploads/";
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
$uploadOk = 1;
$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);
// Check if image file is a actual image or fake image
if(isset($_POST["submit"])) {
    $check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);
    if($check !== false) {
        echo "File is an image - " . $check["mime"] . ".";
        $uploadOk = 1;
    } else {
        echo "File is not an image.";
        $uploadOk = 0;
    }
}
?>

The 'Access-Control-Allow-Origin' header contains multiple values

when i received this error i spent tons of hours searching solution for this but nothing works, finally i found solution to this problem which is very simple. when ''Access-Control-Allow-Origin' header added more than one time to your response this error occur, check your apache.conf or httpd.conf (Apache server), server side script, and remove unwanted entry header from these files.

import android.support.v7.widget.Toolbar;

import it into your java class

The name of the resource is the name space plus the "pseudo" name space of the path to the file. The "pseudo" name space is made by the sub folder structure using \ (backslashes) instead of . (dots).

public static Stream GetResourceFileStream(String nameSpace, String filePath)
{
    String pseduoName = filePath.Replace('\\', '.');
    Assembly assembly = Assembly.GetExecutingAssembly();
    return assembly.GetManifestResourceStream(nameSpace + "." + pseduoName);
}

The following call:

GetResourceFileStream("my.namespace", "resources\\xml\\my.xml")

will return the stream of my.xml located in the folder-structure resources\xml in the name space: my.namespace.

Use the concatenation operator +, and the fact that numeric types will convert automatically into strings:

var a = 1;
var b = "bob";
var c = b + a;

You can use either:

ActiveCell.Interior.ColorIndex = 28

or

ActiveCell.Interior.Color = RGB(255,0,0)

First I executed:

sudo chown -R $(whoami):admin /usr/local

The following script would obtain the ci.jenkins-ci.org public key certificate in base64-encoded DER format and convert it to an OpenSSH public key file. This code assumes that a 2048-bit RSA key is used and draws a lot from this Ian Boyd's answer. I've explained a bit more how it works in comments to this article in Jenkins wiki.

echo -n "ssh-rsa " > jenkins.pub
curl -sfI https://ci.jenkins-ci.org/ | grep -i X-Instance-Identity | tr -d \\r | cut -d\  -f2 | base64 -d | dd bs=1 skip=32 count=257 status=none | xxd -p -c257 | sed s/^/00000007\ 7373682d727361\ 00000003\ 010001\ 00000101\ / | xxd -p -r | base64 -w0 >> jenkins.pub
echo >> jenkins.pub

I still think that Harry's answer is the simplest and completed but if you need something even simpler, then use:

struct AppError {
    let message: String

    init(message: String) {
        self.message = message
    }
}

extension AppError: LocalizedError {
    var errorDescription: String? { return message }
//    var failureReason: String? { get }
//    var recoverySuggestion: String? { get }
//    var helpAnchor: String? { get }
}

And use or test it like this:

printError(error: AppError(message: "My App Error!!!"))

func print(error: Error) {
    print("We have an ERROR: ", error.localizedDescription)
}

I don't know how it was never made officially, but I've added my own json method to console object for easier printing stringified logs:

Observing Objects (non-primitives) in javascript is a bit like quantum mechanics..what you "measure" might not be the real state, which already have changed.

console.json = console.json || function(argument){_x000D_
    for(var arg=0; arg < arguments.length; ++arg)_x000D_
        console.log(  JSON.stringify(arguments[arg], null, 4)  )_x000D_
}_x000D_
_x000D_
// use example_x000D_
console.json(   [1,'a', null, {a:1}], {a:[1,2]}    )

Many times it is needed to view a stringified version of an Object because printing it as-is (raw Object) will print a "live" version of the object which gets mutated as the program progresses, and will not mirror the state of the object at the logged point-of-time, for example:

var foo = {a:1, b:[1,2,3]}

// lets peek under the hood
console.log(foo) 

// program keeps doing things which affect the observed object
foo.a = 2
foo.b = null

If you don't have NSDate -descriptionWithCalendarFormat:timeZone:locale: available (I don't believe iPhone/Cocoa Touch includes this) you may need to use strftime and monkey around with some C-style strings. You can get the UNIX timestamp from an NSDate using NSDate -timeIntervalSince1970.

For folks who find this posting through the search engines, another possible cause of this problem is from importing the wrong package version of @Transient. Make sure that you import javax.persistence.transient and not some other package.

It is a syntax sugar for faster query writing. Its implementation in pseudocode:

def filter_by(self, **kwargs):
    return self.filter(sql.and_(**kwargs))

For AND you can simply write:

session.query(db.users).filter_by(name='Joe', surname='Dodson')

btw

session.query(db.users).filter(or_(db.users.name=='Ryan', db.users.country=='England'))

can be written as

session.query(db.users).filter((db.users.name=='Ryan') | (db.users.country=='England'))

Also you can get object directly by PK via get method:

Users.query.get(123)
# And even by a composite PK
Users.query.get(123, 321)

When using get case its important that object can be returned without database request from identity map which can be used as cache(associated with transaction)

Here's one, no looping:

(Math.pow(10, 20)+'').replace((/0/g),'1').split('').map(parseFloat);

Fill the '20' for length, use the (optional) regexp for handy transforms and map to ensure datatype. I added a function to the Array prototype to easily pull the parameters of 'map' into your functions.. bit risky, some people strongly oppose touching native prototypes, but it does come in handy..

    Array.prototype.$args = function(idx) {
        idx || (idx = 0);
        return function() {
            return arguments.length > idx ? arguments[idx] : null;
        };
    };

// Keys
(Math.pow(10, 20)+'').replace((/0/g),'1').split('').map(this.$args(1));
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20]

// Matrix
(Math.pow(10, 9)+'').replace((/0/g),'1').split('').map(this.$args(1)).map(this.$args(2))

Use Instead

[ngStyle]="{'background-image':' url(' + instagram?.image + ')'}"

On node or ES6+:

users.map(u => u.name).join(', ')

You could move the common parts to another configuration file and include from both server contexts. This should work:

server {
  listen 80;
  server_name server1.example;
  ...
  include /etc/nginx/include.d/your-common-stuff.conf;
}

server {
  listen 80;
  server_name another-one.example;
  ...
  include /etc/nginx/include.d/your-common-stuff.conf;
}

Edit: Here's an example that's actually copied from my running server. I configure my basic server settings in /etc/nginx/sites-enabled (normal stuff for nginx on Ubuntu/Debian). For example, my main server bunkus.org's configuration file is /etc/nginx/sites-enabled and it looks like this:

server {
  listen   80 default_server;
  listen   [2a01:4f8:120:3105::101:1]:80 default_server;

  include /etc/nginx/include.d/all-common;
  include /etc/nginx/include.d/bunkus.org-common;
  include /etc/nginx/include.d/bunkus.org-80;
}

server {
  listen   443 default_server;
  listen   [2a01:4f8:120:3105::101:1]:443 default_server;

  include /etc/nginx/include.d/all-common;
  include /etc/nginx/include.d/ssl-common;
  include /etc/nginx/include.d/bunkus.org-common;
  include /etc/nginx/include.d/bunkus.org-443;
}

As an example here's the /etc/nginx/include.d/all-common file that's included from both server contexts:

index index.html index.htm index.php .dirindex.php;
try_files $uri $uri/ =404;

location ~ /\.ht {
  deny all;
}

location = /favicon.ico {
  log_not_found off;
  access_log off;
}

location ~ /(README|ChangeLog)$ {
  types { }
  default_type text/plain;
}

Adding to @LorenCK's answer, change

NavUtils.navigateUpFromSameTask(this);

to the code below if your activity can be initiated from another activity and this can become part of task started by some other app

Intent upIntent = NavUtils.getParentActivityIntent(this);
if (NavUtils.shouldUpRecreateTask(this, upIntent)) {
    TaskStackBuilder.create(this)
            .addNextIntentWithParentStack(upIntent)
            .startActivities();
} else {
    NavUtils.navigateUpTo(this, upIntent);
}

This will start a new task and start your Activity's parent Activity which you can define in Manifest like below of Min SDK version <= 15

<meta-data
        android:name="android.support.PARENT_ACTIVITY"
        android:value="com.example.app_name.A" />

Or using parentActivityName if its > 15

You can try jQuery treegrid (http://maxazan.github.io/jquery-treegrid/) or jQuery treetable (http://ludo.cubicphuse.nl/jquery-treetable/)

Both are using HTML <table> tag format and styled the as tree.

The jQuery treetable is using data-tt-id and data-tt-parent-id for determining the parent and child of the tree. Usage example:

<table id="tree">
  <tr data-tt-id="1">
    <td>Parent</td>
  </tr>
  <tr data-tt-id="2" data-tt-parent-id="1">
    <td>Child</td>
  </tr>
</table>
$("#tree").treetable({ expandable: true });

Meanwhile, jQuery treegrid is using only class for styling the tree. Usage example:

<table class="tree">
    <tr class="treegrid-1">
        <td>Root node</td><td>Additional info</td>
    </tr>
    <tr class="treegrid-2 treegrid-parent-1">
        <td>Node 1-1</td><td>Additional info</td>
    </tr>
    <tr class="treegrid-3 treegrid-parent-1">

In my case, I was creating an object declared and initialized together. I just initialized in the constructor or what you can initialize the object when required.

Use this one, I've written this to my app,

<?xml version="1.0" encoding="utf-8"?>
<!--  res/drawable/rounded_edittext.xml -->
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle" android:padding="10dp">
    <solid android:color="#882C383E"/>
    <corners
        android:bottomRightRadius="5dp"
        android:bottomLeftRadius="5dp"
        android:topLeftRadius="5dp"
        android:topRightRadius="5dp"/>
</shape>

Jaanna, the session parameters in Oracle SQL Developer are dependent on your client computer, while the NLS parameters on PL/SQL is from server.

For example the NLS_NUMERIC_CHARACTERS on client computer can be ',.' while it's '.,' on server.

So when you run script from PL/SQL and Oracle SQL Developer the decimal separator can be completely different for the same script, unless you alter session with your expected NLS_NUMERIC_CHARACTERS in the script.

One way to easily test your session parameter is to do:

select to_number(5/2) from dual;

Looks like you need to add win32clipboard to your site-packages. It's part of the pywin32 package

<button id="1" class="clickMe"></button>
<button id="2" class="clickMe"></button>
<button id="3" class="clickMe"></button>

<script>
$('.clickMe').click(function(){
    alert(this.id);
});
</script>

1. Go to Control Panel
2. Double click on Java
3. Open the Security tab
4. Select Medium
5. Click on Apply
6. Restart your web browser

That's it!

I have faced the same problem once too. I have solved it by creating on empty link with a ref to it like so:

linkRef = React.createRef();
render() {
    return (
        <a ref={this.linkRef}/>
    );
}

and in my fetch function i have done something like this:

fetch(/*your params*/)
    }).then(res => {
        return res.blob();
    }).then(blob => {
        const href = window.URL.createObjectURL(blob);
        const a = this.linkRef.current;
        a.download = 'Lebenslauf.pdf';
        a.href = href;
        a.click();
        a.href = '';
    }).catch(err => console.error(err));

basically i have assigned the blobs url(href) to the link, set the download attribute and enforce one click on the link. As far as i understand this is the "basic" idea of the answer provided by @Nate. I dont know if this is a good idea to do it this way... I did.

As Ponies says in a comment, you cannot mix OLAP functions with aggregate functions.

Perhaps it's easier to get the last completion date for each employee, and join that to a dataset containing the last completion date for each of the three targeted courses.

This is an untested idea that should hopefully put you down the right path:

  SELECT employee_number,
         course_code,
         MAX(course_completion_date) AS max_date,
         lcc.LAST_COURSE_COMPLETED
    FROM employee_course_completion ecc
         LEFT JOIN (
             SELECT employee_number,
                    MAX(course_completion_date) AS LAST_COURSE_COMPLETED
               FROM employee_course_completion
              WHERE course_code IN ('M910303', 'M91301R', 'M91301P')
         ) lcc
         ON lcc.employee_number = ecc.employee_number
   WHERE course_code IN ('M910303', 'M91301R', 'M91301P')
GROUP BY employee_number, course_code, lcc.LAST_COURSE_COMPLETED

To call a function inside a same controller in any laravel version follow as bellow

$role = $this->sendRequest('parameter');
// sendRequest is a public function

1 : if you are interested only in the static block of the class , the loading the class only would do , and would execute static blocks then all you need is:

Class.forName("Somthing");

2 : if you are interested in loading the class , execute its static blocks and also want to access its its non static part , then you need an instance and then you need:

Class.forName("Somthing").newInstance();

use style white-space: pre the <pre> tag also modifies the text format which may be undesirable.

First: reload(sys) and setting some random default encoding just regarding the need of an output terminal stream is bad practice. reload often changes things in sys which have been put in place depending on the environment - e.g. sys.stdin/stdout streams, sys.excepthook, etc.

Solving the encode problem on stdout

The best solution I know for solving the encode problem of print'ing unicode strings and beyond-ascii str's (e.g. from literals) on sys.stdout is: to take care of a sys.stdout (file-like object) which is capable and optionally tolerant regarding the needs:

• When sys.stdout.encoding is None for some reason, or non-existing, or erroneously false or "less" than what the stdout terminal or stream really is capable of, then try to provide a correct .encoding attribute. At last by replacing sys.stdout & sys.stderr by a translating file-like object.

• When the terminal / stream still cannot encode all occurring unicode chars, and when you don't want to break print's just because of that, you can introduce an encode-with-replace behavior in the translating file-like object.

Here an example:

#!/usr/bin/env python
# encoding: utf-8
import sys

class SmartStdout:
    def __init__(self, encoding=None, org_stdout=None):
        if org_stdout is None:
            org_stdout = getattr(sys.stdout, 'org_stdout', sys.stdout)
        self.org_stdout = org_stdout
        self.encoding = encoding or \
                        getattr(org_stdout, 'encoding', None) or 'utf-8'
    def write(self, s):
        self.org_stdout.write(s.encode(self.encoding, 'backslashreplace'))
    def __getattr__(self, name):
        return getattr(self.org_stdout, name)

if __name__ == '__main__':
    if sys.stdout.isatty():
        sys.stdout = sys.stderr = SmartStdout()

    us = u'aouäöü?zß²'
    print us
    sys.stdout.flush()

Using beyond-ascii plain string literals in Python 2 / 2 + 3 code

The only good reason to change the global default encoding (to UTF-8 only) I think is regarding an application source code decision - and not because of I/O stream encodings issues: For writing beyond-ascii string literals into code without being forced to always use u'string' style unicode escaping. This can be done rather consistently (despite what anonbadger's article says) by taking care of a Python 2 or Python 2 + 3 source code basis which uses ascii or UTF-8 plain string literals consistently - as far as those strings potentially undergo silent unicode conversion and move between modules or potentially go to stdout. For that, prefer "# encoding: utf-8" or ascii (no declaration). Change or drop libraries which still rely in a very dumb way fatally on ascii default encoding errors beyond chr #127 (which is rare today).

And do like this at application start (and/or via sitecustomize.py) in addition to the SmartStdout scheme above - without using reload(sys):

...
def set_defaultencoding_globally(encoding='utf-8'):
    assert sys.getdefaultencoding() in ('ascii', 'mbcs', encoding)
    import imp
    _sys_org = imp.load_dynamic('_sys_org', 'sys')
    _sys_org.setdefaultencoding(encoding)

if __name__ == '__main__':
    sys.stdout = sys.stderr = SmartStdout()
    set_defaultencoding_globally('utf-8') 
    s = 'aouäöü?zß²'
    print s

This way string literals and most operations (except character iteration) work comfortable without thinking about unicode conversion as if there would be Python3 only. File I/O of course always need special care regarding encodings - as it is in Python3.

Note: plains strings then are implicitely converted from utf-8 to unicode in SmartStdout before being converted to the output stream enconding.

as.character() would be the general way rather than use paste() for its side effect

> v <- 20081101
> date <- as.Date(as.character(v), format = "%Y%m%d")
> date
[1] "2008-11-01"

(I presume this is a simple example and something like this:

v <- "20081101"

isn't possible?)

There are in fact 3 questions in your question :

• Define frontend, middle and back end
• How and when do they overlap ?
• Their associated usual bottlenecks.

What JB King has described is correct, but it is a particular, simple version, where in fact he mapped front, middle and bacn to an MVC layer. He mapped M to the back, V to the front, and C to the middle.

For many people, it is just fine, since they come from the ugly world where even MVC was not applied, and you could have direct DB calls in a view.

However in real, complex web applications, you indeed have two or three different layers, called front, middle and back. Each of them may have an associated database and a controller.

The front-end will be visible by the end-user. It should not be confused with the front-office, which is the UI for parameters and administration of the front. The front-end will usually be some kind of CMS or e-commerce Platform (Magento, etc.)

The middle-end is not compulsory and is where the business logics is. It will be based on a PIM, a MDM tool, or some kind of custom database where you enrich your produts or your articles (for CMS). It'll also be the place where you code business functions that need to be shared between differents frontends (for instance between the PC frontend and the API-based mobile application). Sometimes, an ESB or tool like ActiveMQ will be your middle-end

The back-end will be a 3rd layer, surrouding your source database or your ERP. It may be jsut the API wrting to and reading from your ERP. It may be your supplier DB, if you are doing e-commerce. In fact, it really depends on web projects, but it is always a central repository. It'll be accessed either through a DB call, through an API, or an Hibernate layer, or a full-featured back-end application

This description means that answering the other 2 questions is not possible in this thread, as bottlenecks really depend on what your 3 ends contain : what JB King wrote remains true for simple MVC architectures

at the time the question was asked (5 years ago), maybe the MVC pattern was not yet so widely adopted. Now, there is absolutely no reason why the MVC pattern would not be followed and a view would be tied to DB calls. If you read the question "Are there cases where they MUST overlap, and frontend/backend cannot be separated?" in a broader sense, with 3 different components, then there times when the 3 layers architecture is useless of course. Think of a simple personal blog, you'll not need to pull external data or poll RabbitMQ queues.

For Windows users: You can do as RTA said or through command line do this: Navigate to the locaiton of the eclipse executable then run:

 eclipse.lnk -clean

First check the name of your executable using the command 'dir' on its path

Yes, there are at least 2 solutions for this:

1. Use the script directive (http://docs.angularjs.org/api/ng.directive:script) to put your partials in the initially loaded HTML
2. You could also fill in $templateCache (http://docs.angularjs.org/api/ng.$templateCache) from JavaScript if needed (possibly based on result of $http call)

If you would like to use method (2) to fill in $templateCache you can do it like this:

$templateCache.put('second.html', '<b>Second</b> template');

Of course the templates content could come from a $http call:

$http.get('third.html', {cache:$templateCache});

Here is the plunker those techniques: http://plnkr.co/edit/J6Y2dc?p=preview

it turns out that I got this error because my requested module is not bundled in the minification prosses due to path misspelling

so make sure that your module exists in minified js file (do search for a word within it to be sure)

Note quite as clean, but:

import csv

with open("value.txt", "r") as f:
    csv_reader = reader(f)
    num = '  '
    for row in csv_reader:
        print num, '\t'.join(row)
        if num == '  ':  
            num=0
        num=num+1

Add *.DS_Store to your .gitignore file. That works for me perfectly

This work for me

I set style's font before and make rowheader normally then i set in loop for the style with font bolded on each cell of rowhead. Et voilà first row is bolded.

HSSFWorkbook wb = new HSSFWorkbook();
HSSFSheet sheet = wb.createSheet("FirstSheet");
HSSFRow rowhead = sheet.createRow(0); 
HSSFCellStyle style = wb.createCellStyle();
HSSFFont font = wb.createFont();
font.setFontName(HSSFFont.FONT_ARIAL);
font.setFontHeightInPoints((short)10);
font.setBold(true);
style.setFont(font);
rowhead.createCell(0).setCellValue("ID");
rowhead.createCell(1).setCellValue("First");
rowhead.createCell(2).setCellValue("Second");
rowhead.createCell(3).setCellValue("Third");
for(int j = 0; j<=3; j++)
rowhead.getCell(j).setCellStyle(style);

You should investigate why VBA can't find queryname.

I have a saved query named qryAddLoginfoRow. It inserts a row with the current time into my loginfo table. That query runs successfully when called by name by CurrentDb.Execute.

CurrentDb.Execute "qryAddLoginfoRow"

My guess is that either queryname is a variable holding the name of a query which doesn't exist in the current database's QueryDefs collection, or queryname is the literal name of an existing query but you didn't enclose it in quotes.

Edit: You need to find a way to accept that queryname does not exist in the current db's QueryDefs collection. Add these 2 lines to your VBA code just before the CurrentDb.Execute line.

Debug.Print "queryname = '" & queryname & "'"
Debug.Print CurrentDb.QueryDefs(queryname).Name

The second of those 2 lines will trigger run-time error 3265, "Item not found in this collection." Then go to the Immediate window to verify the name of the query you're asking CurrentDb to Execute.

This has a more elegant explanation and more than one possible solutions. http://kasunh.wordpress.com/2011/10/11/preserving-remote-iphost-while-proxying/

The post describes how to use one popular and one lesser known Apache modules to preserve host/ip while in a setup involving proxying.

Use mod_rpaf module, install and enable it in the backend server and add following directives in the module’s configuration. RPAFenable On
RPAFsethostname On
RPAFproxy_ips 127.0.0.1

if anyone is still experiencing this problem in lion, there is a great article with 19 different tips to view your ~/Library dir. find the article by Dan Frakes here http://www.macworld.com/article/161156/2011/07/view_library_folder_in_lion.html

Remember the directory to the simulator is given below

~/Library/Application Support/iPhone Simulator/User/

You can solve this problem as here :) http://jsfiddle.net/MqM76/217/

HTML:

<input id="inpt" type="text" />
<div id="inpt-width"></div>

JS:

$.fn.textWidth = function(text, font) {
    if (!$.fn.textWidth.fakeEl) $.fn.textWidth.fakeEl =      $('<span>').hide().appendTo(document.body);
    $.fn.textWidth.fakeEl.text(text || this.val() || this.text()).css('font', font || this.css('font'));
    return $.fn.textWidth.fakeEl.width(); 
};

$('#inpt').on('input', function() {
    var padding = 10; //Works as a minimum width
    var valWidth = ($(this).textWidth() + padding) + 'px';
    $('#'+this.id+'-width').html(valWidth);
    $('#inpt').css('width', valWidth);
}).trigger('input');

if the project is not a big ,

1- change the name of folder project

2- make a new project with the same project (before renaming)

3- add existing files from the old project to the new project (totally same , same folders , same names , ...)

4- open the the new project file (as xml ) and the old project

5- copy the new project file (xml content ) and paste it in the old project file

6- delete the old project

7- rename the old folder project to old name

With a small edit to Joseph's code, the element does not require a solid background:

div {
    height: 300px;
    background: url('http://images2.layoutsparks.com/1/190037/serene-nature-scenery-blue.jpg');
    position: relative;
}

div:before {
    content: '';
    position: absolute;
    top: 0; right: 0;
    border-top: 80px solid white;
    border-left: 80px solid rgba(0,0,0,0);
    width: 0;
}

http://jsfiddle.net/2bZAW/1921/

This use of 'rgba(0,0,0,0)' allows the inner 'corner' to be invisible .

You can also edit the 4th parameter 'a', where 0 < a < 1, to have a shadow for more of a 'folded-corner' effect:

http://jsfiddle.net/2bZAW/1922/ (with shadow)

NOTE: RGBA color values are supported in IE9+, Firefox 3+, Chrome, Safari, and in Opera 10+.

In python automatic garbage collection deallocates the variable (pandas DataFrame are also just another object in terms of python). There are different garbage collection strategies that can be tweaked (requires significant learning).

You can manually trigger the garbage collection using

import gc
gc.collect()

But frequent calls to garbage collection is discouraged as it is a costly operation and may affect performance.

Reference

array = [ 'Cat', 'Dog', 'Bird' ]
array.include?("Dog")

If you are using Incapsula's load balancer you'll need to use an IRule to generate a custom header for your server. I created an HTTP_X_FORWARDED_PROTO header that is equal to either "http" if the port is set to 80 and "https" if it is equal to 443.

I tried the above solutions in Python3 but this one seems to be the only one working for me when storing objects in a dict. Basically you make a copy of your dict() and iterate over that while deleting the entries in your original dictionary.

        tmpDict = realDict.copy()
        for key, value in tmpDict.items():
            if value:
                del(realDict[key])

This seems very easy:

>>> hash = "355879ACB6"
>>> hash = hash[:4] + '-' + hash[4:]
>>> print hash
3558-79ACB6

However if you like something like a function do as this:

def insert_dash(string, index):
    return string[:index] + '-' + string[index:]

print insert_dash("355879ACB6", 5)

1. Is it really a .ico, or is it just named ".ico"?
2. What browser are you testing in?

The absolutely easiest way to have a favicon is to place an icon called "favicon.ico" in the root folder. That just works everywhere, no code needed at all.

If you must have it in a subdirectory, use:

<link rel="shortcut icon" href="/img/favicon.ico" />

Note the / before img to ensure it is anchored to the root folder.

i did that this way you need to do this just copy paste it be happy

I came here looking for same answer for node js. So here it is

const events = require('events');
const eventEmitter = new events.EventEmitter();

// Createing state to watch and trigger on change
let x = 10 // x is being watched for changes in do while loops below

do {
    eventEmitter.emit('back to normal');
}
while (x !== 10);

do {
    eventEmitter.emit('something changed');
}
while (x === 10);

What I am doing is setting some event emitters when values are changed and using do while loops to detect it.

document.getElementById('username').value = 'foo';
document.getElementById('login_form').submit();

upload_max_filesize is the limit of any single file. post_max_size is the limit of the entire body of the request, which could include multiple files.

Given post_max_size = 20M and upload_max_filesize = 6M you could upload up to 3 files of 6M each. If instead post_max_size = 6M and upload_max_filesize = 20M then you could only upload one 6M file before hitting post_max_size. It doesn't help to have upload_max_size > post_max_size.

It's not obvious how to recognize going over post_max_size. $_POST and $_FILES will be empty, but $_SERVER['CONTENT_LENGTH'] will be > 0. If the client just didn't upload any post variables or files, then $_SERVER['CONTENT_LENGTH'] will be 0.

Here's what I ended up using.

My data set is using a Unix timestamp for the x-axis and a decimal for the y. Change those datatypes to fit your need. I do all the sum calculations in one iteration for the best possible performance.

SHOW CREATE TABLE bar;

you will get a create statement for that table, edit the table name, or anything else you like, and then execute it.

This will allow you to copy the indexes and also manually tweak the table creation.

You can also run the query within a program.

You could try this

box-shadow:
progid:DXImageTransform.Microsoft.dropshadow(OffX=0, OffY=10, Color='#19000000'), 
progid:DXImageTransform.Microsoft.dropshadow(OffX=10, OffY=20, Color='#19000000'), 
progid:DXImageTransform.Microsoft.dropshadow(OffX=20, OffY=30, Color='#19000000'), 
progid:DXImageTransform.Microsoft.dropshadow(OffX=30, OffY=40, Color='#19000000');

Came across this issue when building a DOM structure. This question helped me solve it. I wanted to use a double chevron as a path separator, but appending a new text node directly resulted in the escaped character code showing, rather than the character itself:

var _div = document.createElement('div');
var _separator = document.createTextNode('»');
//_div.appendChild(_separator); /* this resulted in '»' being displayed */
_div.innerHTML = _separator.textContent; /* this was key */
