The DateTimeFormatInfo class implements this interface, so it allows you to control the formatting of your DateTime strings.

I would keep a record of the jwt version number on the user model. New jwt tokens would set their version to this.

When you validate the jwt, simply check that it has a version number equal to the users current jwt version.

Any time you want to invalidate old jwts, just bump the users jwt version number.

CDATA is a better general solution.

How about

<img style="display: none;" src="a.gif">

That will disable the display completely, and not leave a placeholder

I know I am late to the party, but how about this?

const char* dayNames[] = { [Sunday] = "Sunday", [Monday] = "Monday", /*and so on*/ };
printf("%s", dayNames[Sunday]); // prints "Sunday"

This way, you do not have to manually keep the enum and the char* array in sync. If you are like me, chances are that you will later change the enum, and the char* array will print invalid strings. This may not be a feature universally supported. But afaik, most of the mordern day C compilers support this designated initialier style.

You can read more about designated initializers here.

This means that you must declare strict mode by writing "use strict" at the beginning of the file or the function to use block-scope declarations.

EX:

function test(){
    "use strict";
    let a = 1;
} 

You can try the this class to displays an image read from a URL within a JFrame.

public class ShowImageFromURL {

    public static void show(String urlLocation) {
        Image image = null;
        try {
            URL url = new URL(urlLocation);
            URLConnection conn = url.openConnection();
            conn.setRequestProperty("User-Agent", "Mozilla/5.0");

            conn.connect();
            InputStream urlStream = conn.getInputStream();
            image = ImageIO.read(urlStream);

            JFrame frame = new JFrame();
            JLabel lblimage = new JLabel(new ImageIcon(image));
            frame.getContentPane().add(lblimage, BorderLayout.CENTER);
            frame.setSize(image.getWidth(null) + 50, image.getHeight(null) + 50);
            frame.setVisible(true);

        } catch (IOException e) {
            System.out.println("Something went wrong, sorry:" + e.toString());
            e.printStackTrace();
        }
    }
}

I just tested a couple paths using Excel 2013 on on Windows 7. I found the overall pathname limit to be 213 and the basename length to be 186. At least the error dialog for exceeding basename length is clear:

And trying to move a not-too-long basename to a too-long-pathname is also very clear:

The pathname error is deceptive, though. Quite unhelpful:

This is a lazy Microsoft restriction. There's no good reason for these arbitrary length limits, but in the end, it’s a real bug in the error dialog.

You haven't properly cased your onchange prop in the input. It needs to be onChange in JSX.

<input
  type="text"
  value={this.props.searchString}
  ref="searchStringInput"
  onchange={this.handleChange} <--[should be onChange]
/>  

The topic of passing a value prop to an <input>, and then somehow changing the value passed in response to user interaction using an onChange handler is pretty well-considered in the docs.

They refer to such inputs as Controlled Components, and refer to inputs that instead let the DOM natively handle the input's value and subsequent changes from the user as Uncontrolled Components.

Whenever you set the value prop of an input to some variable, you have a Controlled Component. This means you must change the value of the variable by some programmatic means or else the input will always hold that value and will never change, even when you type -- the native behaviour of the input, to update its value on typing, is overridden by React here.

So, you're correctly taking that variable from state, and have a handler to update the state all set up fine. The problem was because you have onchange and not the correct onChange the handler was never being called and so the value was never being updated when you type into the input. When you do use onChange the handler is called, the value is updated when you type, and you see your changes.

If you are using EL 3.0+, the best approach in this case is as this other answer explained in another topic:

For a Collection it's easy, just use the Colleciton#contains() method in EL.

<h:panelGroup id="p1" rendered="#{bean.panels.contains('p1')}">...</h:panelGroup>
<h:panelGroup id="p2" rendered="#{bean.panels.contains('p2')}">...</h:panelGroup>
<h:panelGroup id="p3" rendered="#{bean.panels.contains('p3')}">...</h:panelGroup>

For an Object[] (array), you'd need a minimum of EL 3.0 and utilize its new Lambda support.

<h:panelGroup id="p1" rendered="#{bean.panels.stream().anyMatch(v -> v == 'p1').get()}">...</h:panelGroup>
<h:panelGroup id="p2" rendered="#{bean.panels.stream().anyMatch(v -> v == 'p2').get()}">...</h:panelGroup>
<h:panelGroup id="p3" rendered="#{bean.panels.stream().anyMatch(v -> v == 'p3').get()}">...</h:panelGroup>

If you're not on EL 3.0 yet, you'd need to create a custom EL function. [...]

Update (2008-09-19 10:05) - Solution:

My Solution: Social engineering, I dug real hard and found someone who knew the schema name.
Technical Solution: Searching the .dmp file did yield the schema name.
Once I knew the schema name, I searched the dump file and learned where to find it.

Places the Schemas name were seen, in the .dmp file:

• <OWNER_NAME>SOURCE_SCHEMA</OWNER_NAME> This was seen before each table name/definition.

• SCHEMA_LIST 'SOURCE_SCHEMA' This was seen near the end of the .dmp.

Interestingly enough, around the SCHEMA_LIST 'SOURCE_SCHEMA' section, it also had the command line used to create the dump, directories used, par files used, windows version it was run on, and export session settings (language, date formats).

So, problem solved :)

@Produces({"text/plain","application/xml","application/json"}) change this to @Produces("text/plain") and try,

Judging by the declaration and description of the startsWith Java function, the "most straight forward way" to implement it in VBA would either be with Left:

Public Function startsWith(str As String, prefix As String) As Boolean
    startsWith = Left(str, Len(prefix)) = prefix
End Function

Or, if you want to have the offset parameter available, with Mid:

Public Function startsWith(str As String, prefix As String, Optional toffset As Integer = 0) As Boolean
    startsWith = Mid(str, toffset + 1, Len(prefix)) = prefix
End Function

Actually, neither statement says anything about heap or stack. The code

Object o;

creates one of the following, depending on its context:

• a local variable with automatic storage,
• a static variable at namespace or file scope,
• a member variable that designates the subobject of another object.

This means that the storage location is determined by the context in which the object is defined. In addition, the C++ standard does not talk about stack vs heap storage. Instead, it talks about storage duration, which can be either automatic, dynamic, static or thread-local. However, most implementations implement automatic storage via the call stack, and dynamic storage via the heap.

Local variables, which have automatic storage, are thus created on the stack. Static (and thread-local) objects are generally allocated in their own memory regions, neither on the stack nor on the heap. And member variables are allocated wherever the object they belong to is allocated. They have their containing object’s storage duration.

To illustrate this with an example:

struct Foo {
    Object o;
};

Foo foo;

int main() {
    Foo f;
    Foo* p = new Foo;
    Foo* pf = &f;
}

Now where is the object Foo::o (that is, the subobject o of an object of class Foo) created? It depends:

• foo.o has static storage because foo has static storage, and therefore lives neither on the stack nor on the heap.
• f.o has automatic storage since f has automatic storage (= it lives on the stack).
• p->o has dynamic storage since *p has dynamic storage (= it lives on the heap).
• pf->o is the same object as f.o because pf points to f.

In fact, both p and pf in the above have automatic storage. A pointer’s storage is indistinguishable from any other object’s, it is determined by context. Furthermore, the initialising expression has no effect on the pointer storage.

The pointee (= what the pointer points to) is a completely different matter, and could refer to any kind of storage: *p is dynamic, whereas *pf is automatic.

At first I thought that this would work:

select DBMS_Random.Value(1,9) output
from   ...

However, this does not generate an even distribution of output values:

select output,
       count(*)
from   (
       select round(dbms_random.value(1,9)) output
       from   dual
       connect by level <= 1000000)
group by output
order by 1

1   62423
2   125302
3   125038
4   125207
5   124892
6   124235
7   124832
8   125514
9   62557

The reasons are pretty obvious I think.

I'd suggest using something like:

floor(dbms_random.value(1,10))

Hence:

select output,
       count(*)
from   (
       select floor(dbms_random.value(1,10)) output
       from   dual
       connect by level <= 1000000)
group by output
order by 1

1   111038
2   110912
3   111155
4   111125
5   111084
6   111328
7   110873
8   111532
9   110953

For those of you who don't want to get rid of the bouncing but just to know when it stops (for example to start some calculation of screen distances), you can do the following (container is the overflowing container element):

    const isBouncing = this.container.scrollTop < 0 ||
    this.container.scrollTop + this.container.offsetHeight >
        this.container.scrollHeight

You can write an extension to use it with all the UIViews eg. UIButton, UILabel, UIImageView etc. You can customise my following method as per your requirement, but I think it will work well for you.

extension UIView{

    func setBorder(radius:CGFloat, color:UIColor = UIColor.clearColor()) -> UIView{
        var roundView:UIView = self
        roundView.layer.cornerRadius = CGFloat(radius)
        roundView.layer.borderWidth = 1
        roundView.layer.borderColor = color.CGColor
        roundView.clipsToBounds = true
        return roundView
    }
}

Usage:

btnLogin.setBorder(7, color: UIColor.lightGrayColor())
imgViewUserPick.setBorder(10)

Git keeps all of its files in the .git directory. Just remove that one and init again.

This post well show you how to find the hide .git file on Windows, Mac OSX, Ubuntu

Fetching data with either null and value on where conditions are very tricky. Even if you are using straight Where and OrWhereNotNull condition then for every rows you will fetch both items ignoring other where conditions if applied. For example if you have more where conditions it will mask out those and still return with either null or value items because you used orWhere condition

The best way so far I found is as follows. This works as where (whereIn Or WhereNotNull)

Code::where(function ($query) {
            $query->where('to_be_used_by_user_id', '!=' , 2)->orWhereNull('to_be_used_by_user_id');                  
        })->get();

I know I am late, but what worked for me (total git newbie) was executing the following set of git commands:

git rm -r --cached . 
git add .
git commit -am "Remove ignored files and resubmitting files

To give credit where it is due, here is the link to the source.

My new answer is to use ffmpeg to transcode the .mov like ffmpeg -i sourceFile.mov destinationFile.mp4. Do same for the webm format.

OLD Answer: Here's what you do:

1. Upload your video to Youtube.
2. Install the "Complete YouTube Saver" plugin for Firefox
3. Using the plugin in Firefox, download both the MP4 and WEBM formats and place them on your Web server
4. Add the HTML5 Video element to your webpage per MDN's recommendation

<video controls>
  <source src="somevideo.webm" type="video/webm">
  <source src="somevideo.mp4" type="video/mp4">
  I'm sorry; your browser doesn't support HTML5 video in WebM with VP8/VP9 or MP4 with H.264.
  <!-- You can embed a Flash player here, to play your mp4 video in older browsers -->
</video>

5. Style the <video> element with CSS to suit your needs. For example Materializecss has a simple helper class to render the video nicely across device types.

one way

awk '/^\*\*/{gsub("*","");printf "\n"$0" ";next}{printf $0" "}' to-plot.xls

Yes, it is possible both in Sublime Text 2 and 3 (which you should really upgrade to if you haven't already). Select View ? Ruler ? 80 (there are several other options there as well). If you like to actually wrap your text at 80 columns, select View ? Word Wrap Column ? 80. Make sure that View ? Word Wrap is selected.

To make your selections permanent (the default for all opened files or views), open Preferences ? Settings—User and use any of the following rules:

{
    // set vertical rulers in specified columns.
    // Use "rulers": [80] for just one ruler
    // default value is []
    "rulers": [80, 100, 120],

    // turn on word wrap for source and text
    // default value is "auto", which means off for source and on for text
    "word_wrap": true,

    // set word wrapping at this column
    // default value is 0, meaning wrapping occurs at window width
    "wrap_width": 80
}

These settings can also be used in a .sublime-project file to set defaults on a per-project basis, or in a syntax-specific .sublime-settings file if you only want them to apply to files written in a certain language (Python.sublime-settings vs. JavaScript.sublime-settings, for example). Access these settings files by opening a file with the desired syntax, then selecting Preferences ? Settings—More ? Syntax Specific—User.

As always, if you have multiple entries in your settings file, separate them with commas , except for after the last one. The entire content should be enclosed in curly braces { }. Basically, make sure it's valid JSON.

If you'd like a key combo to automatically set the ruler at 80 for a particular view/file, or you are interested in learning how to set the value without using the mouse, please see my answer here.

Finally, as mentioned in another answer, you really should be using a monospace font in order for your code to line up correctly. Other types of fonts have variable-width letters, which means one 80-character line may not appear to be the same length as another 80-character line with different content, and your indentations will look all messed up. Sublime has monospace fonts set by default, but you can of course choose any one you want. Personally, I really like Liberation Mono. It has glyphs to support many different languages and Unicode characters, looks good at a variety of different sizes, and (most importantly for a programming font) clearly differentiates between 0 and O (digit zero and capital letter oh) and 1 and l (digit one and lowercase letter ell), which not all monospace fonts do, unfortunately. Version 2.0 and later of the font are licensed under the open-source SIL Open Font License 1.1 (here is the FAQ).

In case the solution did not help to just suspend resharper (STRG+R, STRG+R did still not work for example) I decided to disable the plugin and restart visual studio.

Wanted to add the Swift version of Serhii's answer. I created a UIBarExtension.swift with the following:

import Foundation
import UIKit

extension UINavigationBar {
    func hideBottomHairline() {
        self.hairlineImageView?.isHidden = true
    }

    func showBottomHairline() {
        self.hairlineImageView?.isHidden = false
    }
}

extension UIToolbar {
    func hideBottomHairline() {
        self.hairlineImageView?.isHidden = true
    }

    func showBottomHairline() {
        self.hairlineImageView?.isHidden = false
    }
}

extension UIView {
    fileprivate var hairlineImageView: UIImageView? {
        return hairlineImageView(in: self)
    }

    fileprivate func hairlineImageView(in view: UIView) -> UIImageView? {
        if let imageView = view as? UIImageView, imageView.bounds.height <= 1.0 {
            return imageView
        }

        for subview in view.subviews {
            if let imageView = self.hairlineImageView(in: subview) { return imageView }
        }

        return nil
    }
}

Dijkstra's algorithm applies more to weighted paths and it sounds like the poster was wanting to find all paths, not just the shortest.

For this application, I'd build a graph (your application sounds like it wouldn't need to be directed) and use your favorite search method. It sounds like you want all paths, not just a guess at the shortest one, so use a simple recursive algorithm of your choice.

The only problem with this is if the graph can be cyclic.

With the connections:

• 1, 2
• 1, 3
• 2, 3
• 2, 4

While looking for a path from 1->4, you could have a cycle of 1 -> 2 -> 3 -> 1.

In that case, then I'd keep a stack as traversing the nodes. Here's a list with the steps for that graph and the resulting stack (sorry for the formatting - no table option):

current node (possible next nodes minus where we came from) [stack]

1. 1 (2, 3) [1]
2. 2 (3, 4) [1, 2]
3. 3 (1) [1, 2, 3]
4. 1 (2, 3) [1, 2, 3, 1] //error - duplicate number on the stack - cycle detected
5. 3 () [1, 2, 3] // back-stepped to node three and popped 1 off the stack. No more nodes to explore from here
6. 2 (4) [1, 2] // back-stepped to node 2 and popped 1 off the stack.
7. 4 () [1, 2, 4] // Target node found - record stack for a path. No more nodes to explore from here
8. 2 () [1, 2] //back-stepped to node 2 and popped 4 off the stack. No more nodes to explore from here
9. 1 (3) [1] //back-stepped to node 1 and popped 2 off the stack.
10. 3 (2) [1, 3]
11. 2 (1, 4) [1, 3, 2]
12. 1 (2, 3) [1, 3, 2, 1] //error - duplicate number on the stack - cycle detected
13. 2 (4) [1, 3, 2] //back-stepped to node 2 and popped 1 off the stack
14. 4 () [1, 3, 2, 4] Target node found - record stack for a path. No more nodes to explore from here
15. 2 () [1, 3, 2] //back-stepped to node 2 and popped 4 off the stack. No more nodes
16. 3 () [1, 3] // back-stepped to node 3 and popped 2 off the stack. No more nodes
17. 1 () [1] // back-stepped to node 1 and popped 3 off the stack. No more nodes
18. Done with 2 recorded paths of [1, 2, 4] and [1, 3, 2, 4]

I used AutoIt to do it.

using AutoIt;
AutoItX.MouseClick("LEFT",150,150,1,0);//1: click once, 0: Move instantaneous

1. Pro:
   • simple
   • regardless of mouse movement
2. Con:
   • since coordinate is screen-based, there should be some caution if the app scales.
   • the drive won't know when the app finish with clicking consequence actions. There should be a waiting period.

Incredibly, my solution to the same error was to just re-arrange the columns. For anyone else doing the above solutions and still not getting past the error.

I apparently had to arrange the columns in my CSV file to match the same sequence in the table listing in PGADmin.

    public static string GetLocationIPAPI(string ipaddress)
    {
        try
        {
            IPDataIPAPI ipInfo = new IPDataIPAPI();
            string strResponse = new WebClient().DownloadString("http://ip-api.com/json/" + ipaddress);
            if (strResponse == null || strResponse == "") return "";
            ipInfo = JsonConvert.DeserializeObject<IPDataIPAPI>(strResponse);
            if (ipInfo == null || ipInfo.status.ToLower().Trim() == "fail") return "";
            else return ipInfo.city + "; " + ipInfo.regionName + "; " + ipInfo.country + "; " + ipInfo.countryCode;
        }
        catch (Exception)
        {
            return "";
        }
    }

    public string ip { get; set; }
    public string city { get; set; }

    public string loc { get; set; }

To only modify the title's font (and not the font of the axis) I used this:

import matplotlib.pyplot as plt
fig = plt.Figure()
ax = fig.add_subplot(111)
ax.set_title('My Title', fontdict={'fontsize': 8, 'fontweight': 'medium'})

The fontdict accepts all kwargs from matplotlib.text.Text.

An alternative is to use reduction: (this example uses strings but could easily apply to any object type including User)

List<String> list = ImmutableList.of("one", "two", "three", "four", "five", "two");
String match = list.stream().filter("two"::equals).reduce(thereCanBeOnlyOne()).get();
//throws NoSuchElementException if there are no matching elements - "zero"
//throws RuntimeException if duplicates are found - "two"
//otherwise returns the match - "one"
...

//Reduction operator that throws RuntimeException if there are duplicates
private static <T> BinaryOperator<T> thereCanBeOnlyOne()
{
    return (a, b) -> {throw new RuntimeException("Duplicate elements found: " + a + " and " + b);};
}

So for the case with User you would have:

User match = users.stream().filter((user) -> user.getId() < 0).reduce(thereCanBeOnlyOne()).get();

The best way to solve this issue is using the formula to calculate a slope:

(y1-y2/x1-x2)

*define x1 as the first moment, so value will be "C4=1" define x2 as the first moment, so value will be "C5=2"

In order to get the correct percentage growth we can follow this order:

=(((B4-B5)/(C4-C5))/ABS(B4))*100

Perfectly Works!

Arrays are better in performance. ArrayList provides additional functionality such as "remove" at the cost of performance.

You have to chose 'Fill' in the Dock property.

I had the same problem with the bootstrap 3 and solved like this:

$('#myModal').on('shown.bs.modal', function (e) {
    $(this).find('input[type=text]:visible:first').focus();
})

$('#myModal').modal('show').trigger('shown');

Well you just remove the desired item from the list using the remove() method of your ArrayAdapter.

A possible way to do that would be:

Object toRemove = arrayAdapter.getItem([POSITION]);
arrayAdapter.remove(toRemove);

Another way would be to modify the ArrayList and call notifyDataSetChanged() on the ArrayAdapter.

arrayList.remove([INDEX]);
arrayAdapter.notifyDataSetChanged();

I tried android:launchMode="singleTask", but it didn't help. Worked for me using android:launchMode="singleInstance"

Please pay attention to the comments after the 2 lines.

.box1 {
    display: block;
    padding: 10px;
    margin-bottom: 100px; /* SIMPLY SET THIS PROPERTY AS MUCH AS YOU WANT. This changes the space below box1 */
    text-align: justify;
}

.box2 {
    display: block;
    padding: 10px;
    text-align: justify;
    margin-top: 100px; /* OR ADD THIS LINE AND SET YOUR PROPER SPACE as the space above box2 */
}

Jquery does this for you, only thing is to set $.support.cors = true; Then cross domain request works fine in all browsers for jquery users.

If I understand your issue this should work

&emsp—the em space; this should be a very wide space, typically as much as four real spaces. &ensp—the en space; this should be a somewhat wide space, roughly two regular spaces. &thinsp—this will be a narrow space, even more narrow than a regular space.

As Alex says, it works very well. The only tricky part is to remember to make any changes in the cmake files, rather than from within Visual Studio. So on all platforms, the workflow is similar to if you'd used plain old makefiles.

But it's fairly easy to work with, and I've had no issues with cmake generating invalid files or anything like that, so I wouldn't worry too much.

See if this is what you want to do:

@echo off
for /f "delims=" %%a in ('wmic OS Get localdatetime  ^| find "."') do set dt=%%a
set YYYY=%dt:~0,4%
set MM=%dt:~4,2%
set DD=%dt:~6,2%
set HH=%dt:~8,2%
set Min=%dt:~10,2%
set Sec=%dt:~12,2%

set stamp=%YYYY%-%MM%-%DD%_%HH%-%Min%-%Sec%

copy "F:\Folder\File 1.xlsx" "F:\Folder\Archive\File 1 - %stamp%.xlsx"

Easiest way is to open CMD or powershell as administrator and type

set PATH=%PATH%;C:\Python27

This is not about the difference between Window.ContentRendered and Window.Loaded but about what how the Window.Loaded event can be used:

I use it to avoid splash screens in all applications which need a long time to come up.

    // initializing my main window
    public MyAppMainWindow()
    {
        InitializeComponent();

        // Set the event
        this.ContentRendered += MyAppMainWindow_ContentRendered;
    }

    private void MyAppMainWindow_ContentRendered(object sender, EventArgs e)
    {
        // ... comes up quick when the controls are loaded and rendered

        // unset the event
        this.ContentRendered -= MyAppMainWindow_ContentRendered;

        // ... make the time comsuming init stuff here
    }

This is what I ended up using. Temporarily sets target to _blank, then sets it back.

OnClientClick="var originalTarget = document.forms[0].target; document.forms[0].target = '_blank'; setTimeout(function () { document.forms[0].target = originalTarget; }, 3000);"

dtList  = dtList.Where(s => !string.IsNullOrWhiteSpace(s)).Distinct().ToList()

I assumed empty string and whitespace are like null. If not you can use IsNullOrEmpty (allow whitespace), or s != null

Try this

import pandas as pd
data=pd.read_csv('C:/Users/Downloads/winequality-red.csv')

Replace the file target location, with where your data set is found, refer this url https://medium.com/@kanchanardj/jargon-in-python-used-in-data-science-to-laymans-language-part-one-12ddfd31592f

Copy the image then paste it to drawables in the resource folder of you project in android studio.Make sure the name of your image is not too long and does not have any spacial characters.Then click SRC(source) under properties and look for your image click on it then it will automatically get imported to you image view on you emulator.

Form Post Action :

<form method="post" action="{{url('login')}}" accept-charset="UTF-8">

Change your Route : In Routes -> Web.php

Route::post('login','WelcomeController@log_in');

It should be (new minus old)/mod avg of old and new With a special case when both val are zeros

Three steps needed:

1. Explicitly mark SSL2.0, TLS1.0, TLS1.1 as forbidden on your server machine, by adding Enabled=0 and DisabledByDefault=1 to your registry (the full path is HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols). See screen for details

2. Explicitly enable TLS1.2 by following the steps from 1. Just use Enabled=1 and DisabledByDefault=0 respectively.

NOTE: verify server version: Windows Server 2003 does not support the TLS 1.2 protocol

3. Enable TLS1.2 only on app level, like @John Wu suggested above.

   System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

Hope this guide helps.

UPDATE As @Subbu mentioned: Official guide

There are two basic techniques. The first uses PSAPI; MSDN has an example that uses EnumProcesses, OpenProcess, EnumProcessModules, and GetModuleBaseName.

The other uses Toolhelp, which I prefer. Use CreateToolhelp32Snapshot to get a snapshot of the process list, walk over it with Process32First and Process32Next, which provides module name and process ID, until you find the one you want, and then call OpenProcess to get a handle.

Open the file using vi or nano. and then press " i " ,

For save and quit

  Enter Esc    

and write the following command

I would recommend to use sftp, use this command sftp -oPort=7777 user@host where -oPort is custom port number of ssh , in case if u changed it to 7777, then u can use -oPort, else if use only port 22 then plain sftp user@host which asks for the password , then u can log in, and u can navigate to required location using cd /home/user then a simple command get table u can download it, If u want to download a directory/folder get -r someDirectory will do it. If u want the file permissions also to exist then get -Pr someDirectory. For uploading on to remote change get to put in above commands.

In case you are working in the latest toolbar in android studio then here is the smallest solution To change the toolbar options menu color, add this to your toolbar element

 app:popupTheme="@style/MyDarkToolbarStyle"

Then in your styles.xml define the popup menu style

<style name="MyDarkToolbarStyle" parent="ThemeOverlay.AppCompat.Light"> <item name="android:colorBackground">@color/mtrl_white_100</item> <item name="android:textColor">@color/mtrl_light_blue_900</item> </style>

Note that you need to use colorBackground not background. The latter would be applied to everything (the menu itself and each menu item), the former applies only to the popup menu.

To get class name you can use ReflectionClass

class MyClass {
    public function myNameIs(){
        return (new \ReflectionClass($this))->getShortName();
    }
}

Here the query:

Same Table:

UPDATE table_name 
SET column1 = column2

Different Table:

UPDATE table_name1 
    SET column1 = (
        SELECT column2
        FROM table_name2
        WHERE table_name1.id = table_name2.id
    );

The .join() function is using the index of the passed as argument dataset, so you should use set_index or use .merge function instead.

Please find the two examples that should work in your case:

join_df = LS_sgo.join(MSU_pi.set_index('mukey'), on='mukey', how='left')

or

join_df = df_a.merge(df_b, on='mukey', how='left')

Look here.

Basically you have to do bind params:

$sql = "SELECT username FROM users WHERE locationid IN (SELECT locationid FROM locations WHERE countryid=?)"; 

$this->db->query($sql, '__COUNTRY_NAME__');

But, like Mr.E said, use joins:

$sql = "select username from users inner join locations on users.locationid = locations.locationid where countryid = ?"; 

$this->db->query($sql, '__COUNTRY_NAME__');

Tested and Working over Chrome, Firefox, Opera and Edge by 2016/10. Should work on any browser and should always look as expected.

Ok, I did a little cross-browser experiment for printing background colors. Just copy, paste & enjoy!

You can add a div with runat="server" to the page:

<div runat="server" id="myDiv">
</div>

and then set its InnerHtml property from the code-behind:

myDiv.InnerHtml = "your html here";

If you want to modify the DIV's contents on the client side, then you can use javascript code similar to this:

<script type="text/javascript">
    Sys.Application.add_load(MyLoad);
    function MyLoad(sender) {
        $get('<%= div.ClientID %>').innerHTML += " - text added on client";
    }
</script>

You'll want to do floating point division, and then use the ceiling function, to round up the value to the next integer.

In Visual Studio 2010 the key sequence CTRL+E, S will also toggle display of whitespace characters.

Here is a PHP function that will insert a row only if all the specified columns values don't already exist in the table.

• If one of the columns differ, the row will be added.

• If the table is empty, the row will be added.

• If a row exists where all the specified columns have the specified values, the row won't be added.

  function insert_unique($table, $vars)
  {
    if (count($vars)) {
      $table = mysql_real_escape_string($table);
      $vars = array_map('mysql_real_escape_string', $vars);
  
      $req = "INSERT INTO `$table` (`". join('`, `', array_keys($vars)) ."`) ";
      $req .= "SELECT '". join("', '", $vars) ."' FROM DUAL ";
      $req .= "WHERE NOT EXISTS (SELECT 1 FROM `$table` WHERE ";
  
      foreach ($vars AS $col => $val)
        $req .= "`$col`='$val' AND ";
  
      $req = substr($req, 0, -5) . ") LIMIT 1";
  
      $res = mysql_query($req) OR die();
      return mysql_insert_id();
    }
  
    return False;
  }
  

Example usage :

<?php
insert_unique('mytable', array(
  'mycolumn1' => 'myvalue1',
  'mycolumn2' => 'myvalue2',
  'mycolumn3' => 'myvalue3'
  )
);
?>

Open Eclipse, navigate to Window -> Preferences -> Java -> Code Style -> Code Templates -> Comments -> Types and then press the 'Edit' button. There you can change your name in the generated comment from @Author ${user} to @Author Rajish.

Get rid of the parentheses.

Sample batch file:

echo "%1"

if ("%1"=="") echo match1

if "%1"=="" echo match2

Output from running above script:

C:\>echo "" 
""

C:\>if ("" == "") echo match1 

C:\>if "" == "" echo match2 
match2

I think it is actually taking the parentheses to be part of the strings and they are being compared.

Simply remove the dot for the relative import and do:

from p_02_paying_debt_off_in_a_year import compute_balance_after

You can use Jquery's on method and listen for the scroll event.

Excel 2016 I had a similar problem when I created a workbook/file and then I changed the names but somehow the old workbook name was kept. After a lot of googling... well, didn't find any final answer there...

With the release of JDK 10 on March 20, Java now includes a var reserved type name (not a keyword—see below) as specified in JEP 286. For local variables, the following is now valid in Java 10 or higher:

var map = new HashMap<String, Integer>();

The var reserved type name in Java is nearly identical to the var keyword in C# in that both allow for implicit typing (see below for important differences). var in Java can only be used for implicit type inference in the following contexts (as enumerated in JEP 286: Goals):

• local variables with initializers
• indexes in the enhanced for-loop
• locals declared in a traditional for-loop

Therefore var cannot be used for fields, return types, class names, or interface names. Its rationale is to remove the need for including long type names when declaring and defining local variables, as stated in JEP 286 (authored by Brian Goetz):

We seek to improve the developer experience by reducing the ceremony associated with writing Java code, while maintaining Java's commitment to static type safety, by allowing developers to elide the often-unnecessary manifest declaration of local variable types.

var Scoping in Java

It should be noted that var is not a keyword in Java, but rather a reserved type name. As quoted from JEP 286:

The identifier var is not a keyword; instead it is a reserved type name. This means that code that uses var as a variable, method, or package name will not be affected; code that uses var as a class or interface name will be affected (but these names are rare in practice, since they violate usual naming conventions).

Note that since var is a reserved type name and not a keyword, it can still be used for package names, method names, and variable names (along with its new type-interference role). For example, the following are all examples of valid uses of var in Java:

var i = 0;
var var = 1;
for (var i = 0; i < 10; i++) { /* ... */ }
public int var() { return 0; }
package var;

As quoted from JEP 286:

This treatment would be restricted to local variables with initializers, indexes in the enhanced for-loop, and locals declared in a traditional for-loop; it would not be available for method formals, constructor formals, method return types, fields, catch formals, or any other kind of variable declaration.

Differences Between var in Java & C

This is one notable difference between var in C# and Java include the following: var can be used as a type name in C# but cannot be used as a class name or interface name in Java. According to the C# documentation (Implicitly Typed Local Variables):

If a type named var is in scope, then the var keyword will resolve to that type name and will not be treated as part of an implicitly typed local variable declaration.

The ability to use var as a type name in C# creates some complexity and introduces some intricate resolution rules, which are avoided by var in Java by disallowing var as a class or interface name. For information on the complexities of var type names in C#, see Restrictions apply to implicitly-typed variable declarations. For more information on the rationale behind the scoping decision for `var in Java, see JEP 286: Scoping Choices.

A couple of days ago I found a very nice solution of this problem. Read about it here. In two words Mike created a AsyncTaskManager that mediates ProgressDialog and AsyncTask. It's very easy to use this solution. You just need to include in your project several interfaces and several classes and in your activity write some simple code and nest your new AsyncTask from BaseTask. I also advice you to read comments because there are some useful tips.

If you want to let the user select the local json file (anywhere on the filesystem), then the following solution works.

It uses uses FileReader and JSON.parser (and no jquery).

  <fieldset>
    <h2>Json File</h2>
     <input type='file' id='fileinput'>
     <input type='button' id='btnLoad' value='Load' onclick='loadFile();'>
  </fieldset>
</form>

  function loadFile() {
    var input, file, fr;

    if (typeof window.FileReader !== 'function') {
      alert("The file API isn't supported on this browser yet.");
      return;
    }

    input = document.getElementById('fileinput');
    if (!input) {
      alert("Um, couldn't find the fileinput element.");
    }
    else if (!input.files) {
      alert("This browser doesn't seem to support the `files` property of file inputs.");
    }
    else if (!input.files[0]) {
      alert("Please select a file before clicking 'Load'");
    }
    else {
      file = input.files[0];
      fr = new FileReader();
      fr.onload = receivedText;
      fr.readAsText(file);
    }

    function receivedText(e) {
      let lines = e.target.result;
      var newArr = JSON.parse(lines);

Open up the Access File you are trying to export SQL data to. Delete any Queries that are there. Everytime you run SQL Server Import wizard, even if it fails, it creates a Query in the Access DB that has to be deleted before you can run the SQL export Wizard again.

These days, there are quite a few modules available for this. I recently wrote a module to do this, because I wasn't satisfied with the numerous diffing modules I found. Its called odiff: https://github.com/Tixit/odiff . I also listed a bunch of the most popular modules and why they weren't acceptable in the readme of odiff, which you could take a look through if odiff doesn't have the properties you want. Here's an example:

var a = [{a:1,b:2,c:3},              {x:1,y: 2, z:3},              {w:9,q:8,r:7}]
var b = [{a:1,b:2,c:3},{t:4,y:5,u:6},{x:1,y:'3',z:3},{t:9,y:9,u:9},{w:9,q:8,r:7}]

var diffs = odiff(a,b)

/* diffs now contains:
[{type: 'add', path:[], index: 2, vals: [{t:9,y:9,u:9}]},
 {type: 'set', path:[1,'y'], val: '3'},
 {type: 'add', path:[], index: 1, vals: [{t:4,y:5,u:6}]}
]
*/

There are more suitable functions for this in os package. But if you have to use os.walk, here is what I come up with

def walkdir(dirname):
    for cur, _dirs, files in os.walk(dirname):
        pref = ''
        head, tail = os.path.split(cur)
        while head:
            pref += '---'
            head, _tail = os.path.split(head)
        print(pref+tail)
        for f in files:
            print(pref+'---'+f)

output:

>>> walkdir('.')
.
---file3
---file2
---my.py
---file1
---A
------file2
------file1
---B
------file3
------file2
------file4
------file1
---__pycache__
------my.cpython-33.pyc

Use ::ng-deep with caution. I used it throughout my app to set the material design toolbar color to different colors throughout my app only to find that when the app was in testing the toolbar colors step on each other. Come to find out it is because these styles becomes global, see this article Here is a working code solution that doesn't bleed into other components.

<mat-toolbar #subbar>
...
</mat-toolbar>

export class BypartSubBarComponent implements AfterViewInit {
  @ViewChild('subbar', { static: false }) subbar: MatToolbar;
  constructor(
    private renderer: Renderer2) { }
  ngAfterViewInit() {
    this.renderer.setStyle(
      this.subbar._elementRef.nativeElement, 'backgroundColor', 'red');
  }

}

signal isn't the most reliable way as it differs in implementations. I would recommend using sigaction. Tom's code would now look like this :

#include <signal.h>
#include <stdlib.h>
#include <stdio.h>
#include <unistd.h>

void my_handler(int s){
           printf("Caught signal %d\n",s);
           exit(1); 

}

int main(int argc,char** argv)
{

   struct sigaction sigIntHandler;

   sigIntHandler.sa_handler = my_handler;
   sigemptyset(&sigIntHandler.sa_mask);
   sigIntHandler.sa_flags = 0;

   sigaction(SIGINT, &sigIntHandler, NULL);

   pause();

   return 0;    
}

I am from Java world, I like args4j because its simple, specification is more readable( thanks to annotations) and produces nicely formatted output.

Here is my example snippet:

Specification

import org.kohsuke.args4j.{CmdLineException, CmdLineParser, Option}

object CliArgs {

  @Option(name = "-list", required = true,
    usage = "List of Nutch Segment(s) Part(s)")
  var pathsList: String = null

  @Option(name = "-workdir", required = true,
    usage = "Work directory.")
  var workDir: String = null

  @Option(name = "-master",
    usage = "Spark master url")
  var masterUrl: String = "local[2]"

}

Parse

//var args = "-listt in.txt -workdir out-2".split(" ")
val parser = new CmdLineParser(CliArgs)
try {
  parser.parseArgument(args.toList.asJava)
} catch {
  case e: CmdLineException =>
    print(s"Error:${e.getMessage}\n Usage:\n")
    parser.printUsage(System.out)
    System.exit(1)
}
println("workDir  :" + CliArgs.workDir)
println("listFile :" + CliArgs.pathsList)
println("master   :" + CliArgs.masterUrl)

On invalid arguments

Error:Option "-list" is required
 Usage:
 -list VAL    : List of Nutch Segment(s) Part(s)
 -master VAL  : Spark master url (default: local[2])
 -workdir VAL : Work directory.

Sticky Session / Session Affinity:

Your data structure and your JSON do not match.

Your JSON is this:

{
    "JsonValues":{
        "id": "MyID",
        ...
    }
}

But the data structure you try to serialize it to is this:

class ValueSet
{
    [JsonProperty("id")]
    public string id
    {
        get;
        set;
    }
    ...
}

You are skipping a step: Your JSON is a class that has one property named JsonValues, which has an object of your ValueSet data structure as value.

Also inside your class your JSON is this:

"values": { ... }

Your data structure is this:

[JsonProperty("values")]
public List<Value> values
{
    get;
    set;
}

Note that { .. } in JSON defines an object, where as [ .. ] defines an array. So according to your JSON you don't have a bunch of values, but you have one values object with the properties value1 and value2 of type Value.

Since the deserializer expects an array but gets an object instead, it does the least non-destructive (Exception) thing it could do: skip the value. Your property values remains with it's default value: null.

If you can: Adjust your JSON. The following would match your data structure and is most likely what you actually want:

{
    "id": "MyID",

     "values": [
         {
            "id": "100",
            "diaplayName": "MyValue1"
         }, {
            "id": "200",
            "diaplayName": "MyValue2"
         }
     ]
}

I have also ran into this error when the package in one of my class files was incorrectly spelled. Many of these answers immediately jump to the Jar files but I would also check to make sure your packages are spelled correctly.

Try this one. Just get the list of latest post dates from each author. Thats it

SELECT wp_posts.* FROM wp_posts WHERE wp_posts.post_status='publish'
AND wp_posts.post_type='post' AND wp_posts.post_date IN(SELECT MAX(wp_posts.post_date) FROM wp_posts GROUP BY wp_posts.post_author) 

I know this is a pretty old thread, but to keep things up to date and more relevant, you can use the more accurate performance.now() functionality to get finer grain timing in javascript.

window.performance = window.performance || {};
performance.now = (function() {
    return performance.now       ||
        performance.mozNow    ||
        performance.msNow     ||
        performance.oNow      ||
        performance.webkitNow ||            
        Date.now  /*none found - fallback to browser default */
})();

if(UI_USER_INTERFACE_IDIOM () == UIUserInterfaceIdiom.pad)
 {
            print("This is iPad")
 }else if (UI_USER_INTERFACE_IDIOM () == UIUserInterfaceIdiom.phone)
 {
            print("This is iPhone");
  }

WhatsApp has chosen Erlang a language built for writing scalable applications that are designed to withstand errors. Erlang uses an abstraction called the Actor model for it's concurrency - http://en.wikipedia.org/wiki/Actor_(programming_language) Instead of the more traditional shared memory approach, actors communicate by sending each other messages. Actors unlike threads are designed to be lightweight. Actors could be on the same machine or on different machines and the message passing abstractions works for both. A simple implementation of WhatsApp could be: Each user/device is represented as an actor. This actor is responsible for handling the inbox of the user, how it gets serialized to disk, the messages that the user sends and the messages that the user receives. Let's assume that Alice and Bob are friends on WhatsApp. So there is an an Alice actor and a Bob actor.

Let's trace a series of messages flowing back and forth:

Alice decides to message Bob. Alice's phone establishes a connection to the WhatsApp server and it is established that this connection is definitely from Alice's phone. Alice now sends via TCP the following message: "For Bob: A giant monster is attacking the Golden Gate Bridge". One of the WhatsApp front end server deserializes this message and delivers this message to the actor called Alice.

Alice the actor decides to serialize this and store it in a file called "Alice's Sent Messages", stored on a replicated file system to prevent data loss due to unpredictable monster rampage. Alice the actor then decides to forward this message to Bob the actor by passing it a message "Msg1 from Alice: A giant monster is attacking the Golden Gate Bridge". Alice the actor can retry with exponential back-off till Bob the actor acknowledges receiving the message.

Bob the actor eventually receives the message from (2) and decides to store this message in a file called "Bob's Inbox". Once it has stored this message durably Bob the actor will acknowledge receiving the message by sending Alice the actor a message of it's own saying "I received Msg1". Alice the actor can now stop it's retry efforts. Bob the actor then checks to see if Bob's phone has an active connection to the server. It does and so Bob the actor streams this message to the device via TCP.

Bob sees this message and replies with "For Alice: Let's create giant robots to fight them". This is now received by Bob the actor as outlined in Step 1. Bob the actor then repeats Step 2 and 3 to make sure Alice eventually receives the idea that will save mankind.

WhatsApp actually uses the XMPP protocol instead of the vastly superior protocol that I outlined above, but you get the point.

You need to destroy old data-table instance and then re-initialize data-table

First Check if data-table instance exist by using $.fn.dataTable.isDataTable

if exist then destroy it and then create new instance like this

    if ($.fn.dataTable.isDataTable('#dataTableExample')) {
        $('#dataTableExample').DataTable().destroy();
    }

    $('#dataTableExample').DataTable({
        responsive: true,
        destroy: true
    });

You could simply have: var result = (str == "true").

You can do it via FileInfo or DirectoryInfo:

DirectoryInfo di = new DirectoryInfo("TempDir");
di.Delete(true);

And then recreate the directory

The .BAK files from SQL server are in Microsoft Tape Format (MTF) ref: http://www.fpns.net/willy/msbackup.htm

The bak file will probably contain the LDF and MDF files that SQL server uses to store the database.

You will need to use SQL server to extract these. SQL Server Express is free and will do the job.

So, install SQL Server Express edition, and open the SQL Server Powershell. There execute sqlcmd -S <COMPUTERNAME>\SQLExpress (whilst logged in as administrator)

then issue the following command.

restore filelistonly from disk='c:\temp\mydbName-2009-09-29-v10.bak';
GO

This will list the contents of the backup - what you need is the first fields that tell you the logical names - one will be the actual database and the other the log file.

RESTORE DATABASE mydbName FROM disk='c:\temp\mydbName-2009-09-29-v10.bak'
WITH 
   MOVE 'mydbName' TO 'c:\temp\mydbName_data.mdf', 
   MOVE 'mydbName_log' TO 'c:\temp\mydbName_data.ldf';
GO

At this point you have extracted the database - then install Microsoft's "Sql Web Data Administrator". together with this export tool and you will have an SQL script that contains the database.

I know this is coming a bit late, but a colleague of mine figured something out:

figure, plot ((1:10),cos(rand(1,10))-0.75,'*-')
hold on
plot ((1:10),zeros(1,10),'k+-')
text([1:10]-0.09,ones(1,10).*-0.015,[{'0' '1'  '2' '3' '4' '5' '6' '7' '8' '9'}])
set(gca,'XTick',[], 'XColor',[1 1 1])
box off

Regarding the freezing issue, we found this occurred when processing CSV files with at least one extremely long line.

To reproduce:

[print(x) for x in (['A' * 54790] + (['a' * 1421] * 10))]

However, it appears to have been fixed in PyCharm 4.5.4, so if you experience this, try updating your PyCharm.

select case
         when exists (SELECT 1 FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = 'Tags' AND COLUMN_NAME = 'ModifiedByUser')
         then 0
         else 1
       end

/<b>(.*?)<\/b>/g

Add g (global) flag after:

/<b>(.*?)<\/b>/g.exec(str)
             //^-----here it is 

However if you want to get all matched elements, then you need something like this:

var str = "<b>Bob</b>, I'm <b>20</b> years old, I like <b>programming</b>.";

var result = str.match(/<b>(.*?)<\/b>/g).map(function(val){
   return val.replace(/<\/?b>/g,'');
});
//result -> ["Bob", "20", "programming"] 

If an element has attributes, regexp will be:

/<b [^>]+>(.*?)<\/b>/g.exec(str)

Calling toDate will create a copy (the documentation is down-right wrong about it not being a copy), of the underlying JS Date object. JS Date object is stored in UTC and will always print to eastern time. Without getting into whether .utc() modifies the underlying object that moment wraps use the code below.

You don't need moment for this.

new Date().getTime()

This works, because JS Date at its core is in UTC from the Unix Epoch. It's extraordinarily confusing and I believe a big flaw in the interface to mix local and UTC times like this with no descriptions in the methods.

UPDATE:

You can register a handler for process.on('exit') and in any other case(SIGINT or unhandled exception) to call process.exit()

process.stdin.resume();//so the program will not close instantly

function exitHandler(options, exitCode) {
    if (options.cleanup) console.log('clean');
    if (exitCode || exitCode === 0) console.log(exitCode);
    if (options.exit) process.exit();
}

//do something when app is closing
process.on('exit', exitHandler.bind(null,{cleanup:true}));

//catches ctrl+c event
process.on('SIGINT', exitHandler.bind(null, {exit:true}));

// catches "kill pid" (for example: nodemon restart)
process.on('SIGUSR1', exitHandler.bind(null, {exit:true}));
process.on('SIGUSR2', exitHandler.bind(null, {exit:true}));

//catches uncaught exceptions
process.on('uncaughtException', exitHandler.bind(null, {exit:true}));

SELECT * 
FROM events 
WHERE start <= '2013-07-22' OR end >= '2013-06-13'

In Java 1.7+, java.nio.charset.StandardCharsets defines constants for Charset including UTF_8.

import java.nio.charset.StandardCharsets;

...

StandardCharsets.UTF_8.name();

For Android: minSdk 19

I've done it like this:

var input = document.querySelector('input[type="file"]')

var data = new FormData()
data.append('file', input.files[0])
data.append('user', 'hubot')

fetch('/avatars', {
  method: 'POST',
  body: data
})

Additionally for gists, it seems you must leave out the username

git remote set-url origin [email protected]:<Project code>

This is a fun Unicode solution.

char[] alpha = new char[26]
for(int i = 0; i < 26; i++){
    alpha[i] = (char)(97 + i)
}

This generates a lower-cased version of alphabet, if you want upper-cased, you can replace '97' with '65'.

Hope this helps.

Further to RolandTumble's answer to Cody Gray's answer, both fine answers, here is another very simple and flexible way, when you know all of the array contents at coding time - e.g. you just want to build an array that contains 1, 10, 20 and 50. This also uses variant declaration, but doesn't use ReDim. Like in Roland's answer, the enumerated count of the number of array elements need not be specifically known, but is obtainable by using uBound.

sub Demo_array()
    Dim MyArray as Variant, MyArray2 as Variant, i as Long

    MyArray = Array(1, 10, 20, 50)  'The key - the powerful Array() statement
    MyArray2 = Array("Apple", "Pear", "Orange") 'strings work too

    For i = 0 to UBound(MyArray)
        Debug.Print i, MyArray(i)
    Next i
    For i = 0 to UBound(MyArray2)
        Debug.Print i, MyArray2(i)
    Next i
End Sub

I love this more than any of the other ways to create arrays. What's great is that you can add or subtract members of the array right there in the Array statement, and nothing else need be done to code. To add Egg to your 3 element food array, you just type

, "Egg"

in the appropriate place, and you're done. Your food array now has the 4 elements, and nothing had to be modified in the Dim, and ReDim is omitted entirely.

If a 0-based array is not desired - i.e., using MyArray(0) - one solution is just to jam a 0 or "" for that first element.

Note, this might be regarded badly by some coding purists; one fair objection would be that "hard data" should be in Const statements, not code statements in routines. Another beef might be that, if you stick 36 elements into an array, you should set a const to 36, rather than code in ignorance of that. The latter objection is debatable, because it imposes a requirement to maintain the Const with 36 rather than relying on uBound. If you add a 37th element but leave the Const at 36, trouble is possible.

This is how you would drop the constraint

ALTER TABLE <schema_name, sysname, dbo>.<table_name, sysname, table_name>
   DROP CONSTRAINT <default_constraint_name, sysname, default_constraint_name>
GO

With a script

-- t-sql scriptlet to drop all constraints on a table
DECLARE @database nvarchar(50)
DECLARE @table nvarchar(50)

set @database = 'dotnetnuke'
set @table = 'tabs'

DECLARE @sql nvarchar(255)
WHILE EXISTS(select * from INFORMATION_SCHEMA.TABLE_CONSTRAINTS where constraint_catalog = @database and table_name = @table)
BEGIN
    select    @sql = 'ALTER TABLE ' + @table + ' DROP CONSTRAINT ' + CONSTRAINT_NAME 
    from    INFORMATION_SCHEMA.TABLE_CONSTRAINTS 
    where    constraint_catalog = @database and 
            table_name = @table
    exec    sp_executesql @sql
END

I had a similar problem. I had some twitter data in MySQL. The data had Line feed( LF or \n) with in the data. I had a requirement of exporting the MySQL data into excel. The LF was messing up my import of csv file. So I did the following -

1. From MySQL exported to CSV with Record separator as CRLF
2. Opened the data in notepad++ 
3. Replaced CRLF (\r\n) with some string I am not expecting in the Data. I used ###~###! as replacement of CRLF
4. Replaced LF (\n) with Space
5. Replaced ###~###! with \r\n, so my record separator are back.
6. Saved and then imported into Excel

NOTE- While replacing CRLF or LF dont forget to Check Excended (\n,\r,\t... Checkbox [look at the left hand bottom of the Dialog Box)

Try this configuration. It worked for me:

<plugin>
    <artifactId>maven-war-plugin</artifactId>
    <version>2.4</version>
    <configuration>
        <warSourceDirectory>mywebRoot</warSourceDirectory>
        <warSourceExcludes>source\**,build\**,dist\**,WEB-INF\lib\*,
            WEB-INF\classes\**,build.*
        </warSourceExcludes>
        <webXml>myproject/source/deploiement/web.xml</webXml>
        <webResources>
            <resource>
                <directory>mywebRoot/WEB-INF/lib</directory>
                <targetPath>WEB-INF/lib</targetPath>
                <includes>
                        <include>mySystemJar1.jar.jar</include>
                         <include>mySystemJar2.jar</include>
                   </includes>
            </resource>
        </webResources>
    </configuration>
</plugin>

I would change the implementation slightly:

First, I create a UnknownMatchException:

@ResponseStatus(HttpStatus.NOT_FOUND)
public class UnknownMatchException extends RuntimeException {
    public UnknownMatchException(String matchId) {
        super("Unknown match: " + matchId);
    }
}

Note the use of @ResponseStatus, which will be recognized by Spring's ResponseStatusExceptionResolver. If the exception is thrown, it will create a response with the corresponding response status. (I also took the liberty of changing the status code to 404 - Not Found which I find more appropriate for this use case, but you can stick to HttpStatus.BAD_REQUEST if you like.)

Next, I would change the MatchService to have the following signature:

interface MatchService {
    public Match findMatch(String matchId);
}

Finally, I would update the controller and delegate to Spring's MappingJackson2HttpMessageConverter to handle the JSON serialization automatically (it is added by default if you add Jackson to the classpath and add either @EnableWebMvc or <mvc:annotation-driven /> to your config, see the reference docs):

@RequestMapping(value = "/matches/{matchId}", produces = MediaType.APPLICATION_JSON_VALUE)
@ResponseBody
public Match match(@PathVariable String matchId) {
    // throws an UnknownMatchException if the matchId is not known 
    return matchService.findMatch(matchId);
}

Note, it is very common to separate the domain objects from the view objects or DTO objects. This can easily be achieved by adding a small DTO factory that returns the serializable JSON object:

@RequestMapping(value = "/matches/{matchId}", produces = MediaType.APPLICATION_JSON_VALUE)
@ResponseBody
public MatchDTO match(@PathVariable String matchId) {
    Match match = matchService.findMatch(matchId);
    return MatchDtoFactory.createDTO(match);
}

Like Vatine wrote: Since go lacks generics it would have to be part of the language and not the standard library. For that you would then have to pollute the language with keywords set, union, intersection, difference, subset...

The other reason is, that it's not clear at all what the "right" implementation of a set is:

1. There is a functional approach:

   func IsInEvenNumbers(n int) bool {
       if n % 2 == 0 {
           return true
       }
      return false
   }
   

This is a set of all even ints. It has a very efficient lookup and union, intersect, difference and subset can easily be done by functional composition.

2. Or you do a has-like approach like Dali showed.

A map does not have that problem, since you store something associated with the value.

After reading a bunch of people's comments online about this, my first reaction was that this is basically one of those really unimportant debates. However, my initial interest was to find out the right format so I could be consistent with my file naming practice.

Long story short, the creator of YAML are saying .yaml, but personally I keep doing .yml. That just makes more sense to me. So I went on the journey to find affirmation and soon enough, I realise that docker uses .yml everywhere. I've been writing docker-compose.yml files all this time, while you keep seeing in kubernetes' docs kubectl apply -f *.yaml...

So, in conclusion, both formats are obviously accepted and if you are on the other end, (ie: writing systems that receive a YAML file as input) you should allow for both. That seems like another snake case versus camel case thingy...

It for example happens in this case here:

void initializeJSP(unknownType Experiment);

Try using std::string instead of just string (and include the <string> header). C++ Standard library classes are within the namespace std::.

Good question here. I think you cannot terminate the script execution. Although I have never looked for it, I have been using the chrome debugger for quite a long time at work. I usually set breakpoints in my javascript code and then I debug the portion of code I'm interested in. When I finish debugging that code, I usually just run the rest of the program or refresh the browser.

If you want to prevent the rest of the script from being executed (e.g. due to AJAX calls that are going to be made) the only thing you can do is to remove that code in the console on-the-fly, thus preventing those calls from being executed, then you could execute the remaining code without problems.

I hope this helps!

P.S: I tried to find out an option for terminating the execution in some tutorials / guides like the following ones, but couldn't find it. As I said before, probably there is no such option.

Pandas dataframe copy warning

When you go and do something like this:

quote_df = quote_df.ix[:,[0,3,2,1,4,5,8,9,30,31]]

pandas.ix in this case returns a new, stand alone dataframe.

Any values you decide to change in this dataframe, will not change the original dataframe.

This is what pandas tries to warn you about.

Why .ix is a bad idea

The .ix object tries to do more than one thing, and for anyone who has read anything about clean code, this is a strong smell.

Given this dataframe:

df = pd.DataFrame({"a": [1,2,3,4], "b": [1,1,2,2]})

Two behaviors:

dfcopy = df.ix[:,["a"]]
dfcopy.a.ix[0] = 2

Behavior one: dfcopy is now a stand alone dataframe. Changing it will not change df

df.ix[0, "a"] = 3

Behavior two: This changes the original dataframe.

Use .loc instead

The pandas developers recognized that the .ix object was quite smelly[speculatively] and thus created two new objects which helps in the accession and assignment of data. (The other being .iloc)

.loc is faster, because it does not try to create a copy of the data.

.loc is meant to modify your existing dataframe inplace, which is more memory efficient.

.loc is predictable, it has one behavior.

The solution

What you are doing in your code example is loading a big file with lots of columns, then modifying it to be smaller.

The pd.read_csv function can help you out with a lot of this and also make the loading of the file a lot faster.

So instead of doing this

quote_df = pd.read_csv(StringIO(str_of_all), sep=',', names=list('ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefg')) #dtype={'A': object, 'B': object, 'C': np.float64}
quote_df.rename(columns={'A':'STK', 'B':'TOpen', 'C':'TPCLOSE', 'D':'TPrice', 'E':'THigh', 'F':'TLow', 'I':'TVol', 'J':'TAmt', 'e':'TDate', 'f':'TTime'}, inplace=True)
quote_df = quote_df.ix[:,[0,3,2,1,4,5,8,9,30,31]]

Do this

columns = ['STK', 'TPrice', 'TPCLOSE', 'TOpen', 'THigh', 'TLow', 'TVol', 'TAmt', 'TDate', 'TTime']
df = pd.read_csv(StringIO(str_of_all), sep=',', usecols=[0,3,2,1,4,5,8,9,30,31])
df.columns = columns

This will only read the columns you are interested in, and name them properly. No need for using the evil .ix object to do magical stuff.

You don't need jQuery, just use javascript's Math.random function.

edit: If you want to have a number from 1 to 6 show randomly every second, you can do something like this:

<span id="number"></span>

<script language="javascript">
  function generate() {
    $('#number').text(Math.floor(Math.random() * 6) + 1);
  }
  setInterval(generate, 1000);
</script>

If you are posting JSON to Django, I think you want request.body (request.raw_post_data on Django < 1.4). This will give you the raw JSON data sent via the post. From there you can process it further.

Here is an example using JavaScript, jQuery, jquery-json and Django.

JavaScript:

var myEvent = {id: calEvent.id, start: calEvent.start, end: calEvent.end,
               allDay: calEvent.allDay };
$.ajax({
    url: '/event/save-json/',
    type: 'POST',
    contentType: 'application/json; charset=utf-8',
    data: $.toJSON(myEvent),
    dataType: 'text',
    success: function(result) {
        alert(result.Result);
    }
});

Django:

def save_events_json(request):
    if request.is_ajax():
        if request.method == 'POST':
            print 'Raw Data: "%s"' % request.body   
    return HttpResponse("OK")

Django < 1.4:

  def save_events_json(request):
    if request.is_ajax():
        if request.method == 'POST':
            print 'Raw Data: "%s"' % request.raw_post_data
    return HttpResponse("OK")

command in one line:

ftp -in -u ftp://username:password@servername/path/to/ localfile

Usually you want dates to be presented to each user in his own local time-

that is why we use GMT (UTC).

Use Date.parse(jsondatestring) to get the local time string,

unless you want your local time shown to each visitor.

In that case, use Anatoly's method.

Is there any particular reason that you need to use find? You can just use ls to find files that match a pattern in a directory.

ls /dev/abc-*

If you do need to use find, you can use the -maxdepth 1 switch to only apply to the specified directory.

I do a goofy mistake and It take me 2 hour to solve It.I mentioned it here for other persons may be help them.The mistake was I enable ssl connector and changed both https and http ports to same number .

Just open Run SQL Command Line and login as sysadmin and then enter below command

Exec DBMS_XDB.SETHTTPPORT(8181);

That's it. You are done.....

Mac Users please execute the below command from terminal to disable the certificate warning.

/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --ignore-certificate-errors --ignore-urlfetcher-cert-requests &> /dev/null

Note that this will also have Google Chrome mark all HTTPS sites as insecure in the URL bar.

You can use this

<div id="carouselExampleSlidesOnly" class="carousel slide" data-ride="carousel" data-interval="4000">

Just add data-interval="1000" where next picture will be after 1 sec.

The short answer is that not only is static useful, it is pretty well always going to be desired.

First, note that static and constexpr are completely independent of each other. static defines the object's lifetime during execution; constexpr specifies that the object should be available during compilation. Compilation and execution are disjoint and discontiguous, both in time and space. So once the program is compiled, constexpr is no longer relevant.

Every variable declared constexpr is implicitly const but const and static are almost orthogonal (except for the interaction with static const integers.)

The C++ object model (§1.9) requires that all objects other than bit-fields occupy at least one byte of memory and have addresses; furthermore all such objects observable in a program at a given moment must have distinct addresses (paragraph 6). This does not quite require the compiler to create a new array on the stack for every invocation of a function with a local non-static const array, because the compiler could take refuge in the as-if principle provided it can prove that no other such object can be observed.

That's not going to be easy to prove, unfortunately, unless the function is trivial (for example, it does not call any other function whose body is not visible within the translation unit) because arrays, more or less by definition, are addresses. So in most cases, the non-static const(expr) array will have to be recreated on the stack at every invocation, which defeats the point of being able to compute it at compile time.

On the other hand, a local static const object is shared by all observers, and furthermore may be initialized even if the function it is defined in is never called. So none of the above applies, and a compiler is free not only to generate only a single instance of it; it is free to generate a single instance of it in read-only storage.

So you should definitely use static constexpr in your example.

However, there is one case where you wouldn't want to use static constexpr. Unless a constexpr declared object is either ODR-used or declared static, the compiler is free to not include it at all. That's pretty useful, because it allows the use of compile-time temporary constexpr arrays without polluting the compiled program with unnecessary bytes. In that case, you would clearly not want to use static, since static is likely to force the object to exist at runtime.

Just add a . to it:

svn checkout file:///home/landonwinters/svn/waterproject/trunk .

That means: check out to current directory.

This function creates a temporary form, then send data using jQuery :

function postToIframe(data,url,target){
    $('body').append('<form action="'+url+'" method="post" target="'+target+'" id="postToIframe"></form>');
    $.each(data,function(n,v){
        $('#postToIframe').append('<input type="hidden" name="'+n+'" value="'+v+'" />');
    });
    $('#postToIframe').submit().remove();
}

target is the 'name' attr of the target iFrame, and data is a JS object :

data={last_name:'Smith',first_name:'John'}

This works for me on OSX.

pkill -f elasticsearch

Use: xmlhttp.setRequestHeader(key, value);

Have Object.keys accessible in the template and use it in *ngFor.

@Component({
  selector: 'app-myview',
  template: `<div *ngFor="let key of objectKeys(items)">{{key + ' : ' + items[key]}}</div>`
})

export class MyComponent {
  objectKeys = Object.keys;
  items = { keyOne: 'value 1', keyTwo: 'value 2', keyThree: 'value 3' };
  constructor(){}
}

How to import a commons-library into netbeans.

1. Evaluate the error message in NetBeans:

   java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory
   

2. NoClassDeffFoundError means somewhere under the hood in the code you used, a method called another method which invoked a class that cannot be found. So what that means is your code did this: MyFoobarClass foobar = new MyFoobarClass() and the compiler is confused because nowhere is defined this MyFoobarClass. This is why you get an error.

3. To know what to do next, you have to look at the error message closely. The words 'org/apache/commons' lets you know that this is the codebase that provides the tools you need. You have a choice, either you can import EVERYTHING in apache commons, or you could import JUST the LogFactory class, or you could do something in between. Like for example just get the logging bit of apache commons.

4. You'll want to go the middle of the road and get commons-logging. Excellent choice, fire up the google and search for apache commons-logging. The first link takes you to http://commons.apache.org/proper/commons-logging/. Go to downloads. There you will find the most up-to-date ones. If your project was compiled under ancient versions of commons-logging, then use those same ancient ones because if you use the newer ones, the code may fail because the newer versions are different.

5. You're going to want to download the commons-logging-1.1.3-bin.zip or something to that effect. Read what the name is saying. The .zip means it's a compressed file. commons-logging means that this one should contain the LogFactory class you desire. the middle 1.1.3 means that is the version. if you are compiling for an old version, you'll need to match these up, or else you risk the code not compiling right due to changes due to upgrading.

6. Download that zip. Unzip it. Search around for things that end in .jar. In netbeans right click your project, click properties, click libraries, click "add jar/folder" and import those jars. Save the project, and re-run, and the errors should be gone.

The binaries don't include the source code, so you won't be able to drill down and see what is happening when you debug. As programmers you should be downloading "the source" of apache commons and compiling from source, generating the jars yourself and importing those for experience. You should be smart enough to understand and correct the source code you are importing. These ancient versions of apache commons might have been compiled under an older version of Java, so if you go too far back, they may not even compile unless you compile them under an ancient version of java.

Get highlighted text this way:

window.getSelection().toString()

and of course a special treatment for ie:

document.selection.createRange().htmlText

If you're looking into trying to disable the downloading/saving of your images, scripts won't stop that. You would probably have better luck doing this on a server configuration level (like modifying your .htaccess for example on Apache).

Try asking this on ServerFault.

Off the top of my head, lists allow duplicates. You could quickly implement a UniqueArrayList and override all the add / insert functions to check for contains() before you call the inherited methods. For personal use, you could only implement the add method you use, and override the others to throw an exception in case future programmers try to use the list in a different manner.

npm config set registry "http://registry.npmjs.org"

Solved the issue for me. Note that it wouldn't accecpt a forward slash at the end of the url and it had to be entered exactly as shown above.

my .bash_profile function, it may be of any use

logcat() {
    if [ -z "$1" ]
    then
        echo "Process Id argument missing."; return
    fi
    pidFilter="\b$1\b"
    pid=$(adb shell ps | egrep $pidFilter | cut -c10-15)
    if [ -z "$pid" ]
    then
        echo "Process $1 is not running."; return
    fi
    adb logcat | grep $pid
}

alias logcat-myapp="logcat com.sample.myapp"

Usage:

$ logcat-myapp

$ logcat com.android.something.app

As I found best and suitable option for me and it will work with animation too.

You can use indicator it self as a background.

You can set app:tabIndicatorGravity="stretch" attribute to use as background.

Example:

   <android.support.design.widget.TabLayout
        android:id="@+id/tab_layout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:tabIndicatorGravity="stretch"
        app:tabSelectedTextColor="@color/white"
        app:tabTextColor="@color/colorAccent">

        <android.support.design.widget.TabItem
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Chef" />


        <android.support.design.widget.TabItem
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="User" />

    </android.support.design.widget.TabLayout>

Hope it will helps you.

Here's my approach (full text here http://krkadev.blogspot.com/2010/08/random-numbers-without-repetition.html ).

It should run in O(K) instead of O(N), where K is the number of wanted elements and N is the size of the list to choose from:

public <T> List<T> take(List<T> source, int k) {
 int n = source.size();
 if (k > n) {
   throw new IllegalStateException(
     "Can not take " + k +
     " elements from a list with " + n +
     " elements");
 }
 List<T> result = new ArrayList<T>(k);
 Map<Integer,Integer> used = new HashMap<Integer,Integer>();
 int metric = 0;
 for (int i = 0; i < k; i++) {
   int off = random.nextInt(n - i);
   while (true) {
     metric++;
     Integer redirect = used.put(off, n - i - 1);
     if (redirect == null) {
       break;
     }
     off = redirect;
   }
   result.add(source.get(off));
 }
 assert metric <= 2*k;
 return result;
}

I solved this problem without deleting any keys. Here's how:

1. My device was connected to my computer via USB
2. I made sure Eclipse and android device monitor weren't running.
3. Typed at the commandline prompt: adb kill-server
4. Typed at the commandline prompt: adb start-server
5. After adb was restarted, I got a prompt on my device to authorize which I allowed.

Not particularly easily- if you've lost the pointer to the tip of a branch, it's rather like finding a needle in a haystack. You can find all the commits that don't appear to be referenced any more- git fsck --unreachable will do this for you- but that will include commits that you threw away after a git commit --amend, old commits on branches that you rebased etc etc. So seeing all these commits at once is quite likely far too much information to wade through.

So the flippant answer is, don't lose track of things you're interested in. More seriously, the reflogs will hold references to all the commits you've used for the last 60 days or so by default. More importantly, they will give some context about what those commits are.

The System.IO namespace has loads of methods to help you with file operations. The

Directory.GetFiles() 

method returns an array of strings which represent the files in the target directory.

It appears the default setting for Adobe Reader X is for the toolbars not to be shown by default unless they are explicitly turned on by the user. And even when I turn them back on during a session, they don't show up automatically next time. As such, I suspect you have a preference set contrary to the default.

The state you desire, with the top and left toolbars not shown, is called "Read Mode". If you right-click on the document itself, and then click "Page Display Preferences" in the context menu that is shown, you'll be presented with the Adobe Reader Preferences dialog. (This is the same dialog you can access by opening the Adobe Reader application, and selecting "Preferences" from the "Edit" menu.) In the list shown in the left-hand column of the Preferences dialog, select "Internet". Finally, on the right, ensure that you have the "Display in Read Mode by default" box checked:

You can also turn off the toolbars temporarily by clicking the button at the right of the top toolbar that depicts arrows pointing to opposing corners:

Finally, if you have "Display in Read Mode by default" turned off, but want to instruct the page you're loading not to display the toolbars (i.e., override the user's current preferences), you can append the following to the URL:

#toolbar=0&navpanes=0

So, for example, the following code will disable both the top toolbar (called "toolbar") and the left-hand toolbar (called "navpane"). However, if the user knows the keyboard combination (F8, and perhaps other methods as well), they will still be able to turn them back on.

string url = @"http://www.domain.com/file.pdf#toolbar=0&navpanes=0";
this._WebBrowser.Navigate(url);

You can read more about the parameters that are available for customizing the way PDF files open here on Adobe's developer website.

To solve this, you'll need to install only 2 packages. Follow the steps below.

1. Open atom, go to Packages(top bar) --> Settings View --> Install Packages/Themes.

2. Type "goto" in the search field and click the packages button on the right.

3. Install both "goto(1.8.3)" and "goto-definition(1.1.9)", or later versions. Make sure both of them are enabled after download.
4. If necessary, you can restart atom (for some people).
5. It should be able to work now. Right-Click on the method/attr/whatever, then select "Goto Definition"

In my case, this error was caused by the lack of a mere space. I had this if block in my makefile:

if($(METHOD),opt)
CFLAGS=
endif

which should have been:

if ($(METHOD),opt)
CFLAGS=
endif

with a space after if.

Well, it'd still be convenient (syntactically) if we could declare usual values inside the if's condition. So, here's a trick: you can make the compiler think there is an assignment of Optional.some(T) to a value like so:

    if let i = "abc".firstIndex(of: "a"),
        let i_int = .some(i.utf16Offset(in: "abc")),
        i_int < 1 {
        // Code
    }

delete[] monsters;

Is incorrect because monsters isn't a pointer to a dynamically allocated array, it is an array of pointers. As a class member it will be destroyed automatically when the class instance is destroyed.

Your other implementation is the correct one as the pointers in the array do point to dynamically allocated Monster objects.

Note that with your current memory allocation strategy you probably want to declare your own copy constructor and copy-assignment operator so that unintentional copying doesn't cause double deletes. (If you you want to prevent copying you could declare them as private and not actually implement them.)

Just set targetSdkVersion to 19. The notification icon will be colored. Then wait for Firebase to fix this issue.

The seek function expect's an offset in bytes.

Ascii File Example:

So if you have a text file with the following content:

simple.txt

abc

You can jump 1 byte to skip over the first character as following:

fp = open('simple.txt', 'r')
fp.seek(1)
print fp.readline()
>>> bc

Binary file example gathering width :

fp = open('afile.png', 'rb')
fp.seek(16)
print 'width: {0}'.format(struct.unpack('>i', fp.read(4))[0])
print 'height: ', struct.unpack('>i', fp.read(4))[0]

Note: Once you call read you are changing the position of the read-head, which act's like seek.

LPCWSTR is equivalent to wchar_t const *. It's a pointer to a wide character string that won't be modified by the function call.

You can assign to LPCWSTRs by prepending a L to a string literal: LPCWSTR *myStr = L"Hello World";

LPCTSTR and any other T types, take a string type depending on the Unicode settings for your project. If _UNICODE is defined for your project, the use of T types is the same as the wide character forms, otherwise the Ansi forms. The appropriate function will also be called this way: FindWindowEx is defined as FindWindowExA or FindWindowExW depending on this definition.

While generating the links set the target to the iframes name property and you probably wont have to deal with jquery at all.

<a href="inventory.aspx" target="contentframe"  title="Title Inventory">
<iframe id="iframe1" name="contentframe"  ></iframe>

we must also need to add following in build.gradle(app)

compile 'com.android.support:appcompat-v7:23.1.1'

whenever we are using new layouts or new design features. hope this helps you.

This seems to be implemented as standard in newer versions of angular.

The classes ng-untouched and ng-touched are set respectively before and after the user has had focus on an validated element.

Check Mysqld.exe file is in your bin folder. if it is not there , just copy that file from any other computer and paste it on your bin folder.Just double click. Then run mysql.its solved

When testing for directories remember that every directory contains two special files.

One is called '.' and the other '..'

. is the directory's own name while .. is the name of it's parent directory.

To avoid trailing backslash problems just test to see if the directory knows it's own name.

eg:

if not exist %temp%\buffer\. mkdir %temp%\buffer

Starting from pandas 0.14 (released end of May 2014), postgresql is supported. The sql module now uses sqlalchemy to support different database flavors. You can pass a sqlalchemy engine for a postgresql database (see docs). E.g.:

from sqlalchemy import create_engine
engine = create_engine('postgresql://username:password@localhost:5432/mydatabase')
df.to_sql('table_name', engine)

You are correct that in pandas up to version 0.13.1 postgresql was not supported. If you need to use an older version of pandas, here is a patched version of pandas.io.sql: https://gist.github.com/jorisvandenbossche/10841234.
I wrote this a time ago, so cannot fully guarantee that it always works, buth the basis should be there). If you put that file in your working directory and import it, then you should be able to do (where con is a postgresql connection):

import sql  # the patched version (file is named sql.py)
sql.write_frame(df, 'table_name', con, flavor='postgresql')

I have been having the same problem. I followed Bruno's advice to you and found that adding a KeyListener just to the "first" button in the JFrame (ie, on the top left) did the trick. But I agree with you it is kind of an unsettling solution. So I fiddled around and discovered a neater way to fix it. Just add the line

myChildOfJFrame.requestFocusInWindow();

to your main method, after you've created your instance of your subclass of JFrame and set it visible.

I've found it simple and fast...

   # find . -type f -exec basename {} \; | awk -F"." '{print $NF}' > /tmp/outfile.txt
   # cat /tmp/outfile.txt | sort | uniq -c| sort -n > tmp/outfile_sorted.txt

I would like to give another example where groupby without sort is not working. Adapted from example by James Sulak

from itertools import groupby

things = [("vehicle", "bear"), ("animal", "duck"), ("animal", "cactus"), ("vehicle", "speed boat"), ("vehicle", "school bus")]

for key, group in groupby(things, lambda x: x[0]):
    for thing in group:
        print "A %s is a %s." % (thing[1], key)
    print " "

output is

A bear is a vehicle.

A duck is a animal.
A cactus is a animal.

A speed boat is a vehicle.
A school bus is a vehicle.

there are two groups with vehicule, whereas one could expect only one group

Use a binding, like in this example:

<a href="#new-search" data-bind="click:SearchManager.bind($data,'1')">
  Search Manager
</a>

var ViewModelStructure = function () {
    var self = this;
    this.SearchManager = function (search) {
        console.log(search);
    };
}();

$(document).ready(
    function()
    {
        $("input:checkbox").change(
            function()
            {
                if( $(this).is(":checked") )
                {
                    $("#formName").submit();
                }
            }
        )
    }
);

Though it would probably be better to add classes to each of the checkboxes and do

$(".checkbox_class").change();

so that you can choose which checkboxes submit the form instead of all of them doing it.

Here is the arguments parser. You can mix any string arguments (kept untouched) or escaped options (single or option/value pairs). To test it uncomment last 2 statements and run as:

getargs anystr1 anystr2 /test$1 /test$2=123 /test$3 str anystr3

Escape char is defined as "_SEP_=/", redefine if needed.

@echo off

REM Command line argument parser. Format (both "=" and "space" separators are supported):

REM Returns enviroment variables as:

REM   param2=value2
REM   param3=value3
REM Leading and traling strings are preserved as %1, %2, %3 ... %9 parameters
REM but maximum total number of strings is 9 and max number of leading strings is 8
REM Number of parameters is not limited!

you can put everything in a block and easily write any code that you wish in that block just exactly the below code :

@{
        bool isUserConnected = string.IsNullOrEmpty(Model.CreatorFullName);
        if (isUserConnected)
        { // meaning that the viewing user has not been saved
            <div>
                <div> click to join us </div>
                <a id="login" href="javascript:void(0);" style="display: inline; ">join</a>
            </div>
        }
    }

it helps you to have at first a cleaner code and also you can prevent your page from loading many times different blocks of codes

If you don't want to use a function constructor like in Brian's answer you can use Object.create() instead:-

var myVar = {
count: 0
}

myVar.init = function(n) {
    this.count = n
    this.newDiv()
}

myVar.newDiv = function() {
    var newDiv = document.createElement("div")
    var contents = document.createTextNode("Click me!")
    var func = myVar.func(this)
    newDiv.addEventListener ? 
        newDiv.addEventListener('click', func, false) : 
        newDiv.attachEvent('onclick', func)
    newDiv.appendChild(contents)
    document.getElementsByTagName("body")[0].appendChild(newDiv)
}

myVar.func = function (thys) {
   return function() {
      thys.clickme()
   }
} 

myVar.clickme = function () {
   this.count += 1
   alert(this.count)
}

myVar.init(2)

var myVar1 = Object.create(myVar)
myVar1.init(55) 

var myVar2 = Object.create(myVar)
myVar2.init(150) 

// etc

Strangely, I couldn't get the above to work using newDiv.onClick, but it works with newDiv.addEventListener / newDiv.attachEvent.

Since Object.create is newish, include the following code from Douglas Crockford for older browsers, including IE8.

if (typeof Object.create !== 'function') {
    Object.create = function (o) {
        function F() {}
        F.prototype = o
        return new F()
    }
}

If i is the int, then

char c = i;

makes it a char. You might want to add a check that the value is <128 if it comes from an untrusted source. This is best done with isascii from <ctype.h>, if available on your system (see @Steve Jessop's comment to this answer).

Remove the <br> from the .navcontainer-top li styles.

To call one constructor from another you need to use this() and you need to put it first. In your case the default constructor needs to call the one which takes an argument, not the other ways around.

Use this in web.config:

<sessionState 

  timeout="20" 
/>

The best solution I've found was:

https://github.com/angular/angular-cli/issues/5139#issuecomment-283634059

Basically, you need to include a dummy variable on typings.d.ts, remove any "import * as $ from 'jquery" from your code, and then manually add a tag to jQuery script to your SPA html. This way, webpack won't be in your way, and you should be able to access the same global jQuery variable in all your scripts.

This is not possible in the requested way because there are numbers with two decimal places which can not be expressed exactly using IEEE floating point numbers (for example 1/10 = 0.1 can not be expressed as a Double or Float). The formatting should always happen as the last step before presenting the result to the user.

I guess you are asking because you want to deal with monetary values. There is no way to do this reliably with floating-point numbers, you shoud consider switching to fixed-point arithmetics. This probably means doing all calculations in "cents" instead of "dollars".

Expanding on mjswensen's answer, the command without the filter could take minutes, but the filtered command is almost instant.

PowerShell - List local user accounts

Fast way

Get-WmiObject -Class Win32_UserAccount -Filter  "LocalAccount='True'" | select name, fullname

Slow way

Get-WmiObject -Class Win32_UserAccount |? {$_.localaccount -eq $true} | select name, fullname

This maybe what you're looking for:

awk 'BEGIN {FS=" ";} {printf "'\''%s'\'' ", $1}'

That is, with '\'' you close the opening ', then print a literal ' by escaping it and finally open the ' again.

Thread.stop is deprecated so how do we stop a thread in java ?

Always use interrupt method and future to request cancellation

1. When the task responds to interrupt signal, for example, blocking queue take method.

Callable < String > callable = new Callable < String > () {
    @Override
    public String call() throws Exception {
        String result = "";
        try {
            //assume below take method is blocked as no work is produced.
            result = queue.take();
        } catch (InterruptedException e) {
            Thread.currentThread().interrupt();
        }
        return result;
    }
};
Future future = executor.submit(callable);
try {
    String result = future.get(5, TimeUnit.SECONDS);
} catch (TimeoutException e) {
    logger.error("Thread timedout!");
    return "";
} finally {
    //this will call interrupt on queue which will abort the operation.
    //if it completes before time out, it has no side effects
    future.cancel(true);
}

2. When the task does not respond to interrupt signal.Suppose the task performs socket I/O which does not respond to interrupt signal and thus using above approach will not abort the task, future would time out but the cancel in finally block will have no effect, thread will keep on listening to socket. We can close the socket or call close method on connection if implemented by pool.

public interface CustomCallable < T > extends Callable < T > {
    void cancel();
    RunnableFuture < T > newTask();
}

public class CustomExecutorPool extends ThreadPoolExecutor {
    protected < T > RunnableFuture < T > newTaskFor(Callable < T > callable) {
        if (callable instanceof CancellableTask)
            return ((CancellableTask < T > ) callable).newTask();
        else
            return super.newTaskFor(callable);
    }
}

public abstract class UnblockingIOTask < T > implements CustomCallable < T > {
    public synchronized void cancel() {
        try {
            obj.close();
        } catch (IOException e) {
            logger.error("io exception", e);
        }
    }

    public RunnableFuture < T > newTask() {
        return new FutureTask < T > (this) {
            public boolean cancel(boolean mayInterruptIfRunning) {
                try {
                    this.cancel();
                } finally {
                    return super.cancel(mayInterruptIfRunning);
                }
            }

        };
    }
}

You should let the user do that if they want (and you can't stop them anyway).

Your problem is that you need to know that they have and then assume that they mean OK, not cancel. Replace confirm(x) with myConfirm(x):

function myConfirm(message) {
    var start = Number(new Date());
    var result = confirm(message);
    var end = Number(new Date());
    return (end<(start+10)||result==true);
}

I've your same requirements on a public API for which I used rails-api.

I've also set header in a before filter. It looks like this:

headers['Access-Control-Allow-Origin'] = '*'
headers['Access-Control-Allow-Methods'] = 'POST, PUT, DELETE, GET, OPTIONS'
headers['Access-Control-Request-Method'] = '*'
headers['Access-Control-Allow-Headers'] = 'Origin, X-Requested-With, Content-Type, Accept, Authorization'

It seems you missed the Access-Control-Request-Method header.

You get a recursion error because your attempt to access the self.__dict__ attribute inside __getattribute__ invokes your __getattribute__ again. If you use object's __getattribute__ instead, it works:

class D(object):
    def __init__(self):
        self.test=20
        self.test2=21
    def __getattribute__(self,name):
        if name=='test':
            return 0.
        else:
            return object.__getattribute__(self, name)

This works because object (in this example) is the base class. By calling the base version of __getattribute__ you avoid the recursive hell you were in before.

Ipython output with code in foo.py:

In [1]: from foo import *

In [2]: d = D()

In [3]: d.test
Out[3]: 0.0

In [4]: d.test2
Out[4]: 21

Update:

There's something in the section titled More attribute access for new-style classes in the current documentation, where they recommend doing exactly this to avoid the infinite recursion.

The following approach can be used to get any path of a pathname:

some_path=a/b/c
echo $(basename $some_path)
echo $(basename $(dirname $some_path))
echo $(basename $(dirname $(dirname $some_path)))

Output:

c
b
a

// Collect this information on every request
$aip = $_SERVER['REMOTE_ADDR'];
$bip = $_SERVER['HTTP_X_FORWARDED_FOR'];
$agent = $_SERVER['HTTP_USER_AGENT'];
session_start();

// Do this each time the user successfully logs in.
$_SESSION['ident'] = hash("sha256", $aip . $bip . $agent);

// Do this every time the client makes a request to the server, after authenticating
$ident = hash("sha256", $aip . $bip . $agent);
if ($ident != $_SESSION['ident'])
{
    end_session();
    header("Location: login.php");
    // add some fancy pants GET/POST var headers for login.php, that lets you
    // know in the login page to notify the user of why they're being challenged
    // for login again, etc.
}

What this does is capture 'contextual' information about the user's session, pieces of information which should not change during the life of a single session. A user isn't going to be at a computer in the US and in China at the same time, right? So if the IP address changes suddenly within the same session that strongly implies a session hijacking attempt, so you secure the session by ending the session and forcing the user to re-authenticate. This thwarts the hack attempt, the attacker is also forced to login instead of gaining access to the session. Notify the user of the attempt (ajax it up a bit), and vola, Slightly annoyed+informed user and their session/information is protected.

We throw in User Agent and X-FORWARDED-FOR to do our best to capture uniqueness of a session for systems behind proxies/networks. You may be able to use more information then that, feel free to be creative.

It's not 100%, but it's pretty damn effective.

There's more you can do to protect sessions, expire them, when a user leaves a website and comes back force them to login again maybe. You can detect a user leaving and coming back by capturing a blank HTTP_REFERER (domain was typed in the URL bar), or check if the value in the HTTP_REFERER equals your domain or not (the user clicked an external/crafted link to get to your site).

Expire sessions, don't let them remain valid indefinitely.

Don't rely on cookies, they can be stolen, it's one of the vectors of attack for session hijacking.

To build a .tar.gz (aka .tgz) for an entire directory tree:

import tarfile
import os.path

def make_tarfile(output_filename, source_dir):
    with tarfile.open(output_filename, "w:gz") as tar:
        tar.add(source_dir, arcname=os.path.basename(source_dir))

This will create a gzipped tar archive containing a single top-level folder with the same name and contents as source_dir.

set_time_limit(10000);

$con = mysql_connect('127.0.0.1','root','password');
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

mysql_select_db("db", $con);

$fp = fopen("file.csv", "r");

while( !feof($fp) ) {
  if( !$line = fgetcsv($fp, 1000, ';', '"')) {
     continue;
  }

    $importSQL = "INSERT INTO table_name VALUES('".$line[0]."','".$line[1]."','".$line[2]."')";

    mysql_query($importSQL) or die(mysql_error());  

}

fclose($fp);
mysql_close($con);

Simply go to the directory where the troubling file is, type touch * without quotes in the console, and you should be good.

A more general solution than waiting for an element would be to wait for all the connections to the server to close. This will allow you to wait for all ajax calls to finish, even if they don't have any callback and thus don't affect the page. More details can be found here.

Using C# and jQuery, I have created the following method to wait for all AJax calls to complete (if anyone have more direct ways of accessing JS variables from C#, please comment):

internal void WaitForAjax(int timeOut = 15)
{
    var value = "";
    RepeatUntil(
        () => value = GetJavascriptValue("jQuery.active"), 
        () => value == "0", 
        "Ajax calls did not complete before timeout"
    );
}

internal void RepeatUntil(Action repeat, Func<bool> until, string errorMessage, int timeout = 15)
{
    var end = DateTime.Now + TimeSpan.FromSeconds(timeout);
    var complete = false;

    while (DateTime.Now < end)
    {
        repeat();
        try
        {
            if (until())
            {
                complete = true;
                break;
            }
        }
        catch (Exception)
        { }
        Thread.Sleep(500);
    }
    if (!complete)
        throw new TimeoutException(errorMessage);
}

internal string GetJavascriptValue(string variableName)
{
    var id = Guid.NewGuid().ToString();
    _selenium.RunScript(String.Format(@"window.$('body').append(""<input type='text' value='""+{0}+""' id='{1}'/>"");", variableName, id));
    return _selenium.GetValue(id);
}

Additionally for what was said, if you want integer powers of two, then 1 << x (or 1L << x) is a faster way to calculate 2^x than Math.pow(2,x) or a multiplication loop, and is guaranteed to give you an int (or long) result.

It only uses the lowest 5 (or 6) bits of x (i.e. x & 31 (or x & 63)), though, shifting between 0 and 31 (or 63) bits.

I don't have enough reputation points to comment on the recommendation to use *.csv >> ConcatenatedFile.csv, but I can add a warning:

If you create ConcatenatedFile.csv file in the same directory that you are using for concatenation it will be added to itself.

I just recompiled curl with configure options pointing to the openssl 1.0.2g library folder and include folder, and I still get this message. When I do ldd on curl, it does not show that it uses either libcrypt.so or libssl.so, so I assume this must mean that even though the make and make install succeeded without errors, nevertheless curl does not have HTTPS support? Configure and make was as follows:

./configure --prefix=/local/scratch/PACKAGES/local --with-ssl=/local/scratch/PACKAGES/local/openssl/openssl-1.0.2g --includedir=/local/scratch/PACKAGES/local/include/openssl/openssl-1.0.2g
make
make test
make install

I should mention that libssl.so.1 is in /local/scratch/PACKAGES/local/lib. It is unclear whether the --with-ssl option should point there or to the directory where the openssl install placed the openssl.cnf file. I chose the latter. But if it were supposed to be the former, the make should have failed with an error that it couldn't find the library.

Change this:

 <div class=fetch_results>

To this:

 <div id="fetch_results">

Then the following should work:

$("#fetch_results input").each(function() {
      this.value = "";
  })?

The use of @Qualifier will solve the issue.
Explained as below example : 
public interface PersonType {} // MasterInterface

@Component(value="1.2") 
public class Person implements  PersonType { //Bean implementing the interface
@Qualifier("1.2")
    public void setPerson(PersonType person) {
        this.person = person;
    }
}

@Component(value="1.5")
public class NewPerson implements  PersonType { 
@Qualifier("1.5")
    public void setNewPerson(PersonType newPerson) {
        this.newPerson = newPerson;
    }
}

Now get the application context object in any component class :

Object obj= BeanFactoryAnnotationUtils.qualifiedBeanOfType((ctx).getAutowireCapableBeanFactory(), PersonType.class, type);//type is the qualifier id

you can the object of class of which qualifier id is passed.

You can use

<li ng-repeat="(name, age) in items">{{name}}: {{age}}</li>

See ngRepeat documentation. Example: http://jsfiddle.net/WRtqV/1/

Here is a better script:

$('#mainimage').click(function(e)
{   
    var offset_t = $(this).offset().top - $(window).scrollTop();
    var offset_l = $(this).offset().left - $(window).scrollLeft();

    var left = Math.round( (e.clientX - offset_l) );
    var top = Math.round( (e.clientY - offset_t) );

    alert("Left: " + left + " Top: " + top);

});
