Here is a solution using an overlay that inhibits along with material design spinner that you configure one time in your app and you can call it from anywhere.

app.component.html

(put this somewhere at the root level of your html)

<div class="overlay" [style.height.px]="height" [style.width.px]="width" *ngIf="message.plzWait$ | async">
        <mat-spinner class="plzWait"  mode="indeterminate"></mat-spinner>
</div>

app.component.css

.plzWait{
  position: relative;
  left: calc(50% - 50px);
  top:50%;

}
.overlay{
  position: absolute;
  top:0px;
  left:0px;
  width: 100%;
  height: 100%;
  background: black;
  opacity: .5;
  z-index: 999999;
}

app.component.ts

height = 0;
width = 0;
constructor(
    private message: MessagingService
  }
ngOnInit() {
    this.height = document.body.clientHeight;
    this.width = document.body.clientWidth;
  }

messaging.service.ts

import { Injectable } from '@angular/core';
import { Subject } from 'rxjs';

@Injectable({
    providedIn: 'root',
  })
export class MessagingService {
    // Observable string sources
  private plzWaitObservable = new Subject<boolean>();


  // Public Observables you subscribe to
  public plzWait$ = this.plzWaitObservable.asObservable();

  public plzWait = (wait: boolean) => this.plzWaitObservable.next(wait);
}

Some other component

constructor(private message: MessagingService) { }
somefunction() {
    this.message.plzWait(true);
    setTimeout(() => {
            this.message.plzWait(false);
    }, 5000);
}

Just Remove the type="text/javascript"

<script src="JavaScript/jquery.js" />
<script src="JavaScript/bootstrap-min.js" />

Here is the update - http://jsfiddle.net/andieje/kRX6n/

I discover very simple way to redirect Login Page When session end in MVC. I have already tested it and this works without problems.

In short, I catch session end in _Layout 1 minute before and make redirection.

I try to explain everything step by step.

If we want to session end 30 minute after and redirect to loginPage see this steps:

1. Change the web config like this (set 31 minute):

    <system.web>
       <sessionState timeout="31"></sessionState>
    </system.web>
   

2. Add this JavaScript in _Layout (when session end 1 minute before this code makes redirect, it makes count time after user last action, not first visit on site)

   <script>
       //session end 
       var sessionTimeoutWarning = @Session.Timeout- 1;
   
       var sTimeout = parseInt(sessionTimeoutWarning) * 60 * 1000;
       setTimeout('SessionEnd()', sTimeout);
   
       function SessionEnd() {
           window.location = "/Account/LogOff";
       }
   </script>
   

3. Here is my LogOff Action, which makes only LogOff and redirect LoginIn Page

   public ActionResult LogOff()
   {
       Session["User"] = null; //it's my session variable
       Session.Clear();
       Session.Abandon();
       FormsAuthentication.SignOut(); //you write this when you use FormsAuthentication
       return RedirectToAction("Login", "Account");
   } 
   

I hope this is a very useful code for you.

You can use Collections.sort as follows:

private static void order(List<Person> persons) {

    Collections.sort(persons, new Comparator() {

        public int compare(Object o1, Object o2) {

            String x1 = ((Person) o1).getName();
            String x2 = ((Person) o2).getName();
            int sComp = x1.compareTo(x2);

            if (sComp != 0) {
               return sComp;
            } 

            Integer x1 = ((Person) o1).getAge();
            Integer x2 = ((Person) o2).getAge();
            return x1.compareTo(x2);
    }});
}

List<Persons> is now sorted by name, then by age.

String.compareTo "Compares two strings lexicographically" - from the docs.

Collections.sort is a static method in the native Collections library. It does the actual sorting, you just need to provide a Comparator which defines how two elements in your list should be compared: this is achieved by providing your own implementation of the compare method.

UPDATE 2: without seconds option

No, you can't make the img stretch to fit the div and simultaneously achieve the inverse. You would have an infinite resizing loop. However, you could take some notes from other answers and implement some min and max dimensions but that wasn't the question.

You need to decide if your image will scale to fit its parent or if you want the div to expand to fit its child img.

Using this block tells me you want the image size to be variable so the parent div is the width an image scales to. height: auto is going to keep your image aspect ratio in tact. if you want to stretch the height it needs to be 100% like this fiddle.

img {
    width: 100%;
    height: auto;
}

Maps have also had factory methods added in Java 9. For up to 10 entries Maps have overloaded constructors that take pairs of keys and values. For example we could build a map of various cities and their populations (according to google in October 2016) as follow:

Map<String, Integer> cities = Map.of("Brussels", 1_139000, "Cardiff", 341_000);

The var-args case for Map is a little bit harder, you need to have both keys and values, but in Java, methods can’t have two var-args parameters. So the general case is handled by taking a var-args method of Map.Entry<K, V> objects and adding a static entry() method that constructs them. For example:

Map<String, Integer> cities = Map.ofEntries(
    entry("Brussels", 1139000), 
    entry("Cardiff", 341000)
);

Collection Factory Methods in Java 9

You can simply assign the B to the new column , Like -

df['D'] = df['B']

Example/Demo -

In [1]: import pandas as pd

In [2]: df = pd.DataFrame([['a.1','b.1','c.1'],['a.2','b.2','c.2'],['a.3','b.3','c.3']],columns=['A','B','C'])

In [3]: df
Out[3]:
     A    B    C
0  a.1  b.1  c.1
1  a.2  b.2  c.2
2  a.3  b.3  c.3

In [4]: df['D'] = df['B']                  #<---What you want.

In [5]: df
Out[5]:
     A    B    C    D
0  a.1  b.1  c.1  b.1
1  a.2  b.2  c.2  b.2
2  a.3  b.3  c.3  b.3

In [6]: df.loc[0,'D'] = 'd.1'

In [7]: df
Out[7]:
     A    B    C    D
0  a.1  b.1  c.1  d.1
1  a.2  b.2  c.2  b.2
2  a.3  b.3  c.3  b.3

Here's a method that only uses splitting and joining. It's a little more readable so thought it was worth sharing:

    String.prototype.replaceLast = function (what, replacement) {
        var pcs = this.split(what);
        var lastPc = pcs.pop();
        return pcs.join(what) + replacement + lastPc;
    };

The short version is: The efficient way to use readlines() is to not use it. Ever.

I read some doc notes on readlines(), where people has claimed that this readlines() reads whole file content into memory and hence generally consumes more memory compared to readline() or read().

The documentation for readlines() explicitly guarantees that it reads the whole file into memory, and parses it into lines, and builds a list full of strings out of those lines.

But the documentation for read() likewise guarantees that it reads the whole file into memory, and builds a string, so that doesn't help.

On top of using more memory, this also means you can't do any work until the whole thing is read. If you alternate reading and processing in even the most naive way, you will benefit from at least some pipelining (thanks to the OS disk cache, DMA, CPU pipeline, etc.), so you will be working on one batch while the next batch is being read. But if you force the computer to read the whole file in, then parse the whole file, then run your code, you only get one region of overlapping work for the entire file, instead of one region of overlapping work per read.

You can work around this in three ways:

1. Write a loop around readlines(sizehint), read(size), or readline().
2. Just use the file as a lazy iterator without calling any of these.
3. mmap the file, which allows you to treat it as a giant string without first reading it in.

For example, this has to read all of foo at once:

with open('foo') as f:
    lines = f.readlines()
    for line in lines:
        pass

But this only reads about 8K at a time:

with open('foo') as f:
    while True:
        lines = f.readlines(8192)
        if not lines:
            break
        for line in lines:
            pass

And this only reads one line at a time—although Python is allowed to (and will) pick a nice buffer size to make things faster.

with open('foo') as f:
    while True:
        line = f.readline()
        if not line:
            break
        pass

And this will do the exact same thing as the previous:

with open('foo') as f:
    for line in f:
        pass

Meanwhile:

but should the garbage collector automatically clear that loaded content from memory at the end of my loop, hence at any instant my memory should have only the contents of my currently processed file right ?

Python doesn't make any such guarantees about garbage collection.

The CPython implementation happens to use refcounting for GC, which means that in your code, as soon as file_content gets rebound or goes away, the giant list of strings, and all of the strings within it, will be freed to the freelist, meaning the same memory can be reused again for your next pass.

However, all those allocations, copies, and deallocations aren't free—it's much faster to not do them than to do them.

On top of that, having your strings scattered across a large swath of memory instead of reusing the same small chunk of memory over and over hurts your cache behavior.

Plus, while the memory usage may be constant (or, rather, linear in the size of your largest file, rather than in the sum of your file sizes), that rush of mallocs to expand it the first time will be one of the slowest things you do (which also makes it much harder to do performance comparisons).

Putting it all together, here's how I'd write your program:

for filename in os.listdir(input_dir):
    with open(filename, 'rb') as f:
        if filename.endswith(".gz"):
            f = gzip.open(fileobj=f)
        words = (line.split(delimiter) for line in f)
        ... my logic ...  

Or, maybe:

for filename in os.listdir(input_dir):
    if filename.endswith(".gz"):
        f = gzip.open(filename, 'rb')
    else:
        f = open(filename, 'rb')
    with contextlib.closing(f):
        words = (line.split(delimiter) for line in f)
        ... my logic ...

Java 8+ version for Integer, Long, Double and Float

    List<Integer> ints = Arrays.asList(1, 2, 3, 4, 5);
    List<Long> longs = Arrays.asList(1L, 2L, 3L, 4L, 5L);
    List<Double> doubles = Arrays.asList(1.2d, 2.3d, 3.0d, 4.0d, 5.0d);
    List<Float> floats = Arrays.asList(1.3f, 2.2f, 3.0f, 4.0f, 5.0f);

    long intSum = ints.stream()
            .mapToLong(Integer::longValue)
            .sum();

    long longSum = longs.stream()
            .mapToLong(Long::longValue)
            .sum();

    double doublesSum = doubles.stream()
            .mapToDouble(Double::doubleValue)
            .sum();

    double floatsSum = floats.stream()
            .mapToDouble(Float::doubleValue)
            .sum();

    System.out.println(String.format(
            "Integers: %s, Longs: %s, Doubles: %s, Floats: %s",
            intSum, longSum, doublesSum, floatsSum));

You can use:

WITH index = ...

more info

1) 1 += 2 // equals ?

That is syntactically invalid. The left side must be a variable. For example.

var mynum = 1;
mynum += 2;
// now mynum is 3.

mynum += 2; is just a short form for mynum = mynum + 2;

2)

var data = [1,2,3,4,5];
var sum = 0;
data.forEach(function(value) {
    sum += value; 
});

Sum is now 15. Unrolling the forEach we have:

var sum = 0;
sum += 1; // sum is 1
sum += 2; // sum is 3
sum += 3; // sum is 6
sum += 4; // sum is 10
sum += 5; // sum is 15

you must check this selection must be single selection and editing must be no seleciton during edition and you change setting in uttableviewcell properties also you edit in table view cell style must be custom and identifier must be Rid and section is none

1. First make sure you have MinGW installed.
2. From MinGW installation manager check if you have the mingw32-make package installed.
3. Check if you have added the MinGW bin folder to your PATH. type PATH in your command line and look for the folder. Or on windows 10 go to Control Panel\System and Security\System --> Advanced system settings --> Environment Variables --> System Variables find Path variable, select, Edit and check if it is there. If not just add it!
4. As explained here, create a new file in any of your PATH folders. For example create mingwstartup.bat in the MinGW bin folder. write the line doskey make=mingw32-make.exe inside, save and close it.
5. open Registry Editor by running regedit. As explained here in HKEY_LOCAL_MACHINE or HKEY_CURRENT_USER go to \Software\Microsoft\Command Processor right click on the right panel New --> Expandable String Value and name it AutoRun. double click and enter the path to your .bat file as the Value data (e.g. "C:\MinGW\bin\mingwstartup.bat") the result should look like this:

now every time you open a new terminal make command will run the mingw32-make.exe. I hope it helps.

P.S. If you don't want to see the commands of the .bat file to be printed out to the terminal put @echo off at the top of the batch file.

I think it's so difficult to do this in Python because of the simple fact that you never will not know the name of the variable you're using. So, in his example, you could do:

Instead of:

list_of_dicts = [n_jobs, users, queues, priorities]

dict_of_dicts = {"n_jobs" : n_jobs, "users" : users, "queues" : queues, "priorities" : priorities}

I encountered such a situation where code was circumventing STL's api and writing to the array unsafely when someone resizes it. Adding the assert here caught it:

void Logo::add(const QVector3D &v, const QVector3D &n)
{
 GLfloat *p = m_data.data() + m_count;
 *p++ = v.x();
 *p++ = v.y();
 *p++ = v.z();
 *p++ = n.x();
 *p++ = n.y();
 *p++ = n.z();
 m_count += 6;
 Q_ASSERT( m_count <= m_data.size() );
}

With the constructor:

// create a vector with 20 integer elements
std::vector<int> arr(20);

for(int x = 0; x < 20; ++x)
   arr[x] = x;

Based on generality of this question, I think, that you'll need to setup your own HTTPS proxy on some server online. Do the following steps:

• Prepare your proxy server - install IIS, Apache
• Get valid SSL certificate to avoid security errors (free from startssl.com for example)
• Write a wrapper, which will download insecure content (how to below)
• From your site/app get https://yourproxy.com/?page=http://insecurepage.com

If you simply download remote site content via file_get_contents or similiar, you can still have insecure links to content. You'll have to find them with regex and also replace. Images are hard to solve, but Ï found workaround here: http://foundationphp.com/tutorials/image_proxy.php

Note: While this solution may have worked in some browsers when it was written in 2014, it no longer works. Navigating or redirecting to an HTTP URL in an iframe embedded in an HTTPS page is not permitted by modern browsers, even if the frame started out with an HTTPS URL.

The best solution I created is to simply use google as the ssl proxy...

https://www.google.com/search?q=%http://yourhttpsite.com&btnI=Im+Feeling+Lucky

Tested and works in firefox.

Other Methods:

• Use a Third party such as embed.ly (but it it really only good for well known http APIs).

• Create your own redirect script on an https page you control (a simple javascript redirect on a relative linked page should do the trick. Something like: (you can use any langauge/method)

  https://example.com That has a iframe linking to...

  https://example.com/utilities/redirect.html Which has a simple js redirect script like...

  document.location.href ="http://thenonsslsite.com";

• Alternatively, you could add an RSS feed or write some reader/parser to read the http site and display it within your https site.

• You could/should also recommend to the http site owner that they create an ssl connection. If for no other reason than it increases seo.

Unless you can get the http site owner to create an ssl certificate, the most secure and permanent solution would be to create an RSS feed grabing the content you need (presumably you are not actually 'doing' anything on the http site -that is to say not logging in to any system).

The real issue is that having http elements inside a https site represents a security issue. There are no completely kosher ways around this security risk so the above are just current work arounds.

Note, that you can disable this security measure in most browsers (yourself, not for others). Also note that these 'hacks' may become obsolete over time.

If you're accessing this via a View then try sp_recompile or refreshing views.

sp_recompile:

Causes stored procedures, triggers, and user-defined functions to be recompiled the next time that they are run. It does this by dropping the existing plan from the procedure cache forcing a new plan to be created the next time that the procedure or trigger is run. In a SQL Server Profiler collection, the event SP:CacheInsert is logged instead of the event SP:Recompile.

Arguments

[ @objname= ] 'object'

The qualified or unqualified name of a stored procedure, trigger, table, view, or user-defined function in the current database. object is nvarchar(776), with no default. If object is the name of a stored procedure, trigger, or user-defined function, the stored procedure, trigger, or function will be recompiled the next time that it is run. If object is the name of a table or view, all the stored procedures, triggers, or user-defined functions that reference the table or view will be recompiled the next time that they are run.

Return Code Values

0 (success) or a nonzero number (failure)

Remarks

sp_recompile looks for an object in the current database only.

The queries used by stored procedures, or triggers, and user-defined functions are optimized only when they are compiled. As indexes or other changes that affect statistics are made to the database, compiled stored procedures, triggers, and user-defined functions may lose efficiency. By recompiling stored procedures and triggers that act on a table, you can reoptimize the queries.

You could try as well:

let diceRoll = Int(arc4random_uniform(UInt32(6)))

I had to add "UInt32" to make it work.

You can create it easily:

$structure = './depth1/depth2/depth3/';
if (!mkdir($structure, 0, true)) {
die('Failed to create folders...');
}

I guess you want to do the "Iterating over Keys and Values"

As the doc here says, just add "|keys" in the variable you want and it will magically happen.

{% for key, user in users %}
    <li>{{ key }}: {{ user.username|e }}</li>
{% endfor %}

It never hurts to search before asking :)

This is based on the assumption that you're getting an error about the date format, such as an invalid month value or non-numeric character when numeric expected.

Dates stored in the database do not have formats. When you query the date your client is formatting the date for display, as 4/16/2011. Normally the same date format is used for selecting and updating dates, but in this case they appear to be different - so your client is apparently doing something more complicated that SQL*Plus, for example.

When you try to update it it's using a default date format model. Because of how it's displayed you're assuming that is MM/DD/YYYY, but it seems not to be. You could find out what it is, but it's better not to rely on the default or any implicit format models at all.

Whether that is the problem or not, you should always specify the date model:

UPDATE PASOFDATE SET ASOFDATE = TO_DATE('11/21/2012', 'MM/DD/YYYY');

Since you aren't specifying a time component - all Oracle DATE columns include a time, even if it's midnight - you could also use a date literal:

UPDATE PASOFDATE SET ASOFDATE = DATE '2012-11-21';

You should maybe check that the current value doesn't include a time, though the column name suggests it doesn't.

It ignores the cached content when refreshing...

function wordLimit($str, $limit) {
    $arr = explode(' ', $str);
    if(count($arr) <= $limit){
        return $str;   
    }
    $result = '';

        $result .= $arr[$i].' ';
    }
    return trim($result);
}
echo wordLimit('Hello Word', 1); // Hello
echo wordLimit('Hello Word', 2); // Hello Word
echo wordLimit('Hello Word', 3); // Hello Word
echo wordLimit('Hello Word', 0); // ''

Following worked for me

git pull

Then checkout the required branch

First download plugin manager this link then unzip the zip folder and copy this inside your program/ notepad++ folder . then restart your notepad++. then you see plugin manager inside plugin menu . then click plugin manager then click show plugin manager . It shows all your plugin list . from the list in bottom find XML tools , checked it and install it. then restart your notepad++. After open a document then plugins/xml tools/pretty plain(indent text) then enjoy.

As an extra, you can take the Enum.Parse answers already provided and put them in an easy-to-use static method in a helper class.

public static T ParseEnum<T>(string value)
{
    return (T)Enum.Parse(typeof(T), value, ignoreCase: true);
}

And use it like so:

{
   Content = ParseEnum<ContentEnum>(fileContentMessage);
};

Especially helpful if you have lots of (different) Enums to parse.

An easier way to clear a screen while in python is to use Ctrl + L though it works for the shell as well as other programs.

I found that if ProjectX referenced the abc.dll but didn't directly use any of the types DEFINED in abc.dll, then abc.dll would NOT be copied to the main output folder. (It would be copied to the ProjectX output folder, to make it extra-confusing.)

So, if you're not explicitly using any of the types from abc.dll anywhere in ProjectX, then put a dummy declaration somewhere in one of the files in ProjectX.

AbcDll.AnyClass dummy006; // this will be enough to cause the DLL to be copied

You don't need to do this for every class -- just once will be enough to make the DLL copy and everything work as expected.

Addendum: Note that this may work for debug mode, but NOT for release. See @nvirth's answer for details.

var o = {
    r: 'some value',
    t: 'some other value'
};

is functionally equivalent to

var o = new Object();
o.r = 'some value';
o.t = 'some other value';

For .NET 3.5 and before try :

MemoryStream1.WriteTo(MemoryStream2);

Just addition to above answers ..

[FromUri] can also be used to bind complex types from uri parameters instead of passing parameters from querystring

For Ex..

public class GeoPoint
{
    public double Latitude { get; set; } 
    public double Longitude { get; set; }
}

[RoutePrefix("api/Values")]
public ValuesController : ApiController
{
    [Route("{Latitude}/{Longitude}")]
    public HttpResponseMessage Get([FromUri] GeoPoint location) { ... }
}

Can be called like:

http://localhost/api/values/47.678558/-122.130989

There exist command: goto

if(smth) {
   .....
   .....
   .....
   .....
   .....
   goto Area1;
   .....
   .....


}



Area1:
....your code here....

However, remember goto is not a recommended practice, because it makes the code to be formatted unusually.

you can also do it like that :

$ver = $em->getRepository('GedDocumentBundle:version')->search($val);

$tail = sizeof($ver);

You could use this script:

def run(runfile):
  with open(runfile,"r") as rnf:
    exec(rnf.read())

Syntax:

run("file.py")

The "official" way to get the vs2015 is to go to https://my.visualstudio.com/ ; join the " Visual Studio Dev Essentials" and then search the relevant file to download https://my.visualstudio.com/Downloads?q=Visual%20Studio%202015%20with%20Update%203

I was facing this problem and, as mentioned previously here, I changed the "servers" file under Subversion folder in "C:\Users\userid\AppData\Roaming\Subversion". There, in the file's bottom, there is a [global] section. I removed the comments from

http-proxy-host
http-proxy-port
http-proxy-username
http-proxy-password

I set those guys and it worked! :-)

Inspired by @E.Lahu Solution, implementation of a bar progress with percentage.

public class ConsoleSpinner
{
    private int _counter;

    public void Turn(Color color, int max, string prefix = "Completed", string symbol = "¦",int position = 0)
    {
        Console.SetCursorPosition(0, position);
        Console.Write($"{prefix} {ComputeSpinner(_counter, max, symbol)}", color);
        _counter = _counter == max ? 0 : _counter + 1;
    }

    public string ComputeSpinner(int nmb, int max, string symbol)
    {
        var spinner = new StringBuilder();
        if (nmb == 0)
            return "\r ";

        spinner.Append($"[{nmb}%] [");
        for (var i = 0; i < max; i++)
        {
            spinner.Append(i < nmb ? symbol : ".");
        }

        spinner.Append("]");
        return spinner.ToString();
    }
}


public static void Main(string[] args)
    {
        var progressBar= new ConsoleSpinner();
        for (int i = 0; i < 1000; i++)
        {
            progressBar.Turn(Color.Aqua,100);
            Thread.Sleep(1000);
        }
    }

Can you connect to internet at all through Eclipse?

• Open the internal webbrowser. In Eclipse: Window -> show view -> Other -> General: Internal web browser.
• Look up any normal adress, is it working?

Can you connect to another update site? Try for example Eclipse Emma: http://update.eclemma.org/ Do you see anything there?

What are your proxy preferences? Go to Window -> preferences -> General: Network connections.

The active provider:

Specifies the settings profile to be used when opening connections. Choosing the Direct provider causes all the connections to be opened without the use of a proxy server. Selecting Manual causes settings defined in Eclipse to be used. On some platforms there is also a Native provider available, selecting this one causes settings that were discovered in the OS to be used.

If internet is working fine outside of Eclipse, try changing to Native. After that, try Direct.

I have encountered problems where an update site would not load, then I had to remove it and add it again. This forces Eclipse to reread the contents of the site even if it has a cached copy. So, if you still get no connection to the indigo update site, but everything else is working, try that. Go to Window -> Preferences -> Install/update: Available Software sites. Then remove and add the indigo site. Just remember to copy the adress so you can add it again.

As suggested in a comment below by @lostiniceland, this is a simpler way to achieve the above:

Goto Window -> Preferences -> Install Update -> Available Software Sites => select the entry and click the "Reload" button to the right. This is sometimes also helpful when you have a local updatesite for testing custom plugins

Since the range of numbers is constrained, I'd say the best thing to do is generate the array, fill it with numbers zero through 39 (in order), then shuffle it.

brew doctor checks if Homebrew is installed and working properly.

Oddly none of these solutions tell you if a page has a vertical scrollbar.

window.innerWidth - document.body.clientWidth will give you the width of the scrollbar. This should work in anything IE9+ (not tested in the lesser browsers). (Or to strictly answer the question, !!(window.innerWidth - document.body.clientWidth)

Why? Let's say you have a page where the content is taller than the window height and the user can scroll up/down. If you're using Chrome on a Mac with no mouse plugged in, the user will not see a scrollbar. Plug a mouse in and a scrollbar will appear. (Note this behaviour can be overridden, but that's the default AFAIK).

I am biased being one of the developers of PyMuPDF (a Python binding of MuPDF).

You can easily do what you want with it (and much more). Skeleton code works like this:

#-------------------------------------------------
import fitz         # the binding PyMuPDF
fout = fitz.open()  # new PDF for joined output
flist = ["1.pdf", "2.pdf", ...]  # list of filenames to be joined

for f in flist:
    fin = fitz.open(f)  # open an input file
    fout.insertPDF(fin) # append f
    fin.close()

fout.save("joined.pdf")
#-------------------------------------------------

That's about it. Several options are available for selecting only pages ranges, maintaining a joint table of contents, reversing page sequence or changing page rotation, etc., etc.

We are on PyPi.

There is a nice form plugin that allows you to send an HTML form asynchroniously.

$(document).ready(function() { 
    $('#myForm1').ajaxForm(); 
});

or

$("select").change(function(){
    $('#myForm1').ajaxSubmit();
});

to submit the form immediately

You can use finish() method or you can use:

android:noHistory="true"

And then there is no need to call finish() anymore.

<activity android:name=".ClassName" android:noHistory="true" ... />

Since the exact question is "what does enable bitcode do", I'd like to give a few thin technical details I've figured out thus far. Most of this is practically impossible to figure out with 100% certainty until Apple releases the source code for this compiler

First, Apple's bitcode does not appear to be the same thing as LLVM bytecode. At least, I've not been able to figure out any resemblance between them. It appears to have a proprietary header (always starts with "xar!") and probably some link-time reference magic that prevents data duplications. If you write out a hardcoded string, this string will only be put into the data once, rather than twice as would be expected if it was normal LLVM bytecode.

Second, bitcode is not really shipped in the binary archive as a separate architecture as might be expected. It is not shipped in the same way as say x86 and ARM are put into one binary (FAT archive). Instead, they use a special section in the architecture specific MachO binary named "__LLVM" which is shipped with every architecture supported (ie, duplicated). I assume this is a short coming with their compiler system and may be fixed in the future to avoid the duplication.

C code (compiled with clang -fembed-bitcode hi.c -S -emit-llvm):

#include <stdio.h>

int main() {
    printf("hi there!");
    return 0;
}

LLVM IR output:

The data array that is in the IR also changes depending on the optimization and other code generation settings of clang. It's completely unknown to me what format or anything that this is in.

EDIT:

Following the hint on Twitter, I decided to revisit this and to confirm it. I followed this blog post and used his bitcode extractor tool to get the Apple Archive binary out of the MachO executable.

The only notable difference really between the non-bitcode IR and the bitcode IR is that filenames have been stripped to just 1, 2, etc for each architecture.

I also confirmed that the bitcode embedded in a binary is generated after optimizations. If you compile with -O3 and extract out the bitcode, it'll be different than if you compile with -O0.

And just to get extra credit, I also confirmed that Apple does not ship bitcode to devices when you download an iOS 9 app. They include a number of other strange sections that I don't recognized like __LINKEDIT, but they do not include __LLVM.__bundle, and thus do not appear to include bitcode in the final binary that runs on a device. Oddly enough, Apple still ships fat binaries with separate 32/64bit code to iOS 8 devices though.

To get more than 20 you can use a load more button.

Fedora users WILL NOT be able to do a simple "yum install nodejs" due to serious naming and file placement conflicts that prevent this package from even being available through the Fedora repositories.

There is apparently at least one alternate repository available with an alternate build that may work, but that's two too many "alternates" for me to be willing to use it-- I'm looking for another alternative.

Facebook has revised their policies now. You can’t get the whole friendlist anyway if your app does not have a Canvas implementation and if your app is not a game. Of course there’s also taggable_friends, but that one is for tagging only.

You will be able to pull the list of friends who have authorised the app only.

The apps that are using Graph API 1.0 will be working till April 30th, 2015 and after that it will be deprecated.

See the following to get more details on this:

• User Friends

• Facebook Application Development FAQ

This is one of those "you were technically accurate, but you didn't answer my question" but it doesn't mean the above were wrong or misguided - they just didn't run into my issue.

So, I figure I'll give an answer.

As the others mentioned (spot on), I created a file:

<?php
phpinfo(); 
?>

So that worked great. However, it showed "(none)"

So where do you find (none)!?

In my case, on Windows, you just go to where php is installed; I had already had installed it in c:\php I believe it would be the same steps on other platforms.

Then, from a command line, powershell for ex, type: notepad c:\php\php.ini

Tell it yes, you do want to create it, then add whatever changes you needed in the first place. For me, for example:

extension_dir = "c:\php\ext"
extension=mysqli
upload_max_filesize = 25M
post_max_size = 13M
max_execution_time = 300

Then save. Fixed!

By the way - if you do "file new" and then "save as" Notepad will helpfully rename your file to php.ini.txt. Friends let friends NOT AVOID THE CLI.

Because you are talking about your replacement being anything, and also replacing in the middle of an element's children, it becomes more tricky than just inserting a singular element, or directly removing and appending:

function replaceTargetWith( targetID, html ){
  /// find our target
  var i, tmp, elm, last, target = document.getElementById(targetID);
  /// create a temporary div or tr (to support tds)
  tmp = document.createElement(html.indexOf('<td')!=-1?'tr':'div'));
  /// fill that div with our html, this generates our children
  tmp.innerHTML = html;
  /// step through the temporary div's children and insertBefore our target
  i = tmp.childNodes.length;
  /// the insertBefore method was more complicated than I first thought so I 
  /// have improved it. Have to be careful when dealing with child lists as  
  /// they are counted as live lists and so will update as and when you make
  /// changes. This is why it is best to work backwards when moving children 
  /// around, and why I'm assigning the elements I'm working with to `elm` 
  /// and `last`
  last = target;
  while(i--){
    target.parentNode.insertBefore((elm = tmp.childNodes[i]), last);
    last = elm;
  }
  /// remove the target.
  target.parentNode.removeChild(target);
}

example usage:

replaceTargetWith( 'idTABLE', 'I <b>can</b> be <div>anything</div>' );

demo:

• http://jsfiddle.net/97H5Y/1/

By using the .innerHTML of our temporary div this will generate the TextNodes and Elements we need to insert without any hard work. But rather than insert the temporary div itself -- this would give us mark up that we don't want -- we can just scan and insert it's children.

...either that or look to using jQuery and it's replaceWith method.

jQuery('#idTABLE').replaceWith('<blink>Why this tag??</blink>');

update 2012/11/15

As a response to EL 2002's comment above:

It not always possible. For example, when createElement('div') and set its innerHTML as <td>123</td>, this div becomes <div>123</div> (js throws away inappropriate td tag)

The above problem obviously negates my solution as well - I have updated my code above accordingly (at least for the td issue). However for certain HTML this will occur no matter what you do. All user agents interpret HTML via their own parsing rules, but nearly all of them will attempt to auto-correct bad HTML. The only way to achieve exactly what you are talking about (in some of your examples) is to take the HTML out of the DOM entirely, and manipulate it as a string. This will be the only way to achieve a markup string with the following (jQuery will not get around this issue either):

<table><tr>123 text<td>END</td></tr></table>

If you then take this string an inject it into the DOM, depending on the browser you will get the following:

123 text<table><tr><td>END</td></tr></table>

<table><tr><td>END</td></tr></table>

The only question that remains is why you would want to achieve broken HTML in the first place? :)

myfile.h

#ifndef _myfile_h
#define _myfile_h

void function();

#endif

myfile.c

#include "myfile.h"

void function() {

}

Use the following block of query to update Table1 with Table2 based on ID:

UPDATE Table1, Table2 
SET Table1.DataColumn= Table2.DataColumn
where Table1.ID= Table2.ID;

This is the easiest and fastest way to tackle this problem.

If you want to use straight PowerShell check out the below code.

$content = Get-Content C:\Users\You\Documents\test.txt
foreach ($line in $content)
{
    Write-Host $line
}

I had also the similar issue in godaddy hosting. But after putting ob_start(); at the beginning of the php page from where page was redirecting, it was working fine.

Please find the example of the fix:

fileName:index.php

<?php
ob_start();
...
header('Location: page1.php');
...
ob_end_flush();
?>

Below query will provide exactly the same result as given in the desired response:

db.books.aggregate([
    {
        $group: {
            _id: { addresses: "$addr", books: "$book" },
            num: { $sum :1 }
        }
    },
    {
        $group: {
            _id: "$_id.addresses",
            bookCounts: { $push: { bookName: "$_id.books",count: "$num" } }
        }
    },
    {
        $project: {
            _id: 1,
            bookCounts:1,
            "totalBookAtAddress": {
                "$sum": "$bookCounts.count"
            }
        }
    }

]) 

The response will be looking like below:

I believe the following work in version 0.11 and above. To check the version:

$ ipython --version

It may be worth adding this information to your question.

Solution:

You need to find the file ipython_notebook_config.py. Depending on your installation process this should be in somewhere like

.config/ipython/profile_default/ipython_notebook_config.py

where .config is in your home directory.

Once you have located this file find the following lines

# Subset of matplotlib rcParams that should be different for the inline backend.
# c.InlineBackend.rc = {'font.size': 10, 'figure.figsize': (6.0, 4.0), 'figure.facecolor': 'white', 'savefig.dpi': 72, 'figure.subplot.bottom': 0.125, 'figure.edgecolor': 'white'}

Uncomment this line c.InlineBack... and define your default figsize in the second dictionary entry.

Note that this could be done in a python script (and hence interactively in IPython) using

pylab.rcParams['figure.figsize'] = (10.0, 8.0)

You could also use strdup:

   The strdup() function returns a pointer to a new string which is a duplicate of the string  s.
   Memory for the new string is obtained with malloc(3), and can be freed with free(3).

For you example:

char *a = strdup("stack overflow");

If you want to set it to LF as default, you can go to File->Preferences->Settings and under user settings you can paste this line in below your other user settings.

"files.eol": "\n"

For example.

"git.confirmSync": false,
"window.zoomLevel": -1,
"workbench.activityBar.visible": true,
"editor.wordWrap": true,
"workbench.iconTheme": "vscode-icons",
"window.menuBarVisibility": "default",
"vsicons.projectDetection.autoReload": true,
"files.eol": "\n"

Here is a way to do it in the shell:

FIELD=2
cut -f $FIELD * | sort| uniq -c |sort -nr

This is the sort of thing bash is great at.

Its not really possible to perform a 'mouse hover' action, instead you need to chain all of the actions that you want to achieve in one go. So move to the element that reveals the others, then during the same chain, move to the now revealed element and click on it.

When using Action Chains you have to remember to 'do it like a user would'.

Actions action = new Actions(webdriver);
WebElement we = webdriver.findElement(By.xpath("html/body/div[13]/ul/li[4]/a"));
action.moveToElement(we).moveToElement(webdriver.findElement(By.xpath("/expression-here"))).click().build().perform();

It’s easy; just do the following:

rvm implode

or

rm -rf ~/.rvm

And don’t forget to remove the script calls in the following files:

• ~/.bashrc
• ~/.bash_profile
• ~/.profile

And maybe others depending on whatever shell you’re using.

Dim psValue As String = "1,5,12,34,123,12"
psValue = psValue.Substring(0, psValue.LastIndexOf(","))

output:

1,5,12,34,123

I think it bears repeating: html_safe does not HTML-escape your string. In fact, it will prevent your string from being escaped.

<%= "<script>alert('Hello!')</script>" %>

will put:

<script>alert('Hello!')</script>

into your HTML source (yay, so safe!), while:

<%= "<script>alert('Hello!')</script>".html_safe %>

will pop up the alert dialog (are you sure that's what you want?). So you probably don't want to call html_safe on any user-entered strings.

I think what you originally meant to do was to make an array only of characters, not of pointers:

char options[2][100];

options[0][0]='t';
options[0][1]='e';
options[0][2]='s';
options[0][3]='t';
options[0][4]='1';
options[0][5]='\0';  /* NUL termination of C string */

/* A standard C library function which copies strings. */
strcpy(options[1], "test2");

The code above shows two distinct methods of setting the character values in memory you have set aside to contain characters.

If in your HTML you have an input element with a name or id with a _ like e.g. first_name or more than one _ like e.g. student_first_name and you also have the Javascript code at the bottom of your Web Page and you are sure you are doing everything else right, then those dashes could be what is messing you up.

Having id or name for your input elements resembling the below

<input type="text" id="first_name" name="first_name">

or

<input type="text" id="student_first_name" name="student_first_name">

Then you try make a call like this below in your JavaScript code

var first_name = document.getElementById("first_name").value;

or

var student_first_name = document.getElementById("student_first_name").value;

You are certainly going to have an error like Uncaught TypeError: Cannot read property 'value' of null in Google Chrome and on Internet Explorer too. I did not get to test that with Firefox.

In my case I removed the dashes, in first_name and renamed it to firstname and from student_first_name to studentfirstname

At the end, I was able to resolve that error with my code now looking as follows for HTML and JavaScript.

HTML

<input type="text" id="firstname" name="firstname">

or

<input type="text" id="studentfirstname" name="studentfirstname">

Javascript

var firstname = document.getElementById("firstname").value;

or

var studentfirstname = document.getElementById("studentfirstname").value;

So if it is within your means to rename the HTML and JavaScript code with those dashes, it may help if that is what is ailing your piece of code. In my case that was what was bugging me.

Hope this helps someone stop pulling their hair like I was.

The final keyword in java is used to restrict the user. The java final keyword can be used in many context. Final can be:

1. variable
2. method
3. class

The final keyword can be applied with the variables, a final variable that has no value, is called blank final variable or uninitialized final variable. It can be initialized in the constructor only. The blank final variable can be static also which will be initialized in the static block only.

Java final variable:

If you make any variable as final, you cannot change the value of final variable(It will be constant).

Example of final variable

There is a final variable speedlimit, we are going to change the value of this variable, but It can't be changed because final variable once assigned a value can never be changed.

class Bike9{  
    final int speedlimit=90;//final variable  
    void run(){  
        speedlimit=400;  // this will make error
    }  

    public static void main(String args[]){  
    Bike9 obj=new  Bike9();  
    obj.run();  
    }  
}//end of class  

Java final class:

If you make any class as final, you cannot extend it.

Example of final class

final class Bike{}  

class Honda1 extends Bike{    //cannot inherit from final Bike,this will make error
  void run(){
      System.out.println("running safely with 100kmph");
   }  

  public static void main(String args[]){  
      Honda1 honda= new Honda();  
      honda.run();  
      }  
  }  

Java final method:

If you make any method as final, you cannot override it.

Example of final method (run() in Honda cannot override run() in Bike)

class Bike{  
  final void run(){System.out.println("running");}  
}  

class Honda extends Bike{  
   void run(){System.out.println("running safely with 100kmph");}  

   public static void main(String args[]){  
   Honda honda= new Honda();  
   honda.run();  
   }  
}

If you are new to this space, and consider yourself a security expert, use 2.0 after careful examination of its features. If you are not an expert, either use 1.0 or copy the 2.0 implementation of a provider you trust to get it right (Facebook’s API documents are a good place to start). 2.0 is better for large scale, but if you are running a major operation, you probably have some security experts on site to figure it all out for you."

As per Pipeline plugin tutorial:

If you have configured your pipeline to accept parameters when it is built — Build with Parameters — they are accessible as Groovy variables of the same name.

So try to access the variable directly, e.g.:

node()
{
     print "DEBUG: parameter foo = " + foo
     print "DEBUG: parameter bar = ${bar}"
}

As you said the event window.onbeforeunload fires when the users clicks on a link or refreshes the page, so it would not a good even to end a session.

http://msdn.microsoft.com/en-us/library/ms536907(VS.85).aspx describes all situations where window.onbeforeonload is triggered. (IE)

However, you can place a JavaScript global variable on your pages to identify actions that should not trigger a logoff (by using an AJAX call from onbeforeonload, for example).

The script below relies on JQuery

/*
* autoLogoff.js
*
* Every valid navigation (form submit, click on links) should
* set this variable to true.
*
* If it is left to false the page will try to invalidate the
* session via an AJAX call
*/
var validNavigation = false;

/*
* Invokes the servlet /endSession to invalidate the session.
* No HTML output is returned
*/
function endSession() {
   $.get("<whatever url will end your session>");
}

function wireUpEvents() {

  /*
  * For a list of events that triggers onbeforeunload on IE
  * check http://msdn.microsoft.com/en-us/library/ms536907(VS.85).aspx
  */
  window.onbeforeunload = function() {
      if (!validNavigation) {
         endSession();
      }
  }

  // Attach the event click for all links in the page
  $("a").bind("click", function() {
     validNavigation = true;
  });

  // Attach the event submit for all forms in the page
  $("form").bind("submit", function() {
     validNavigation = true;
  });

}

// Wire up the events as soon as the DOM tree is ready
$(document).ready(function() {
    wireUpEvents();  
});

This script may be included in all pages

<script type="text/javascript" src="js/autoLogoff.js"></script>

Let's go through this code:

  var validNavigation = false;

  window.onbeforeunload = function() {
      if (!validNavigation) {
         endSession();
      }
  }

  // Attach the event click for all links in the page
  $("a").bind("click", function() {
     validNavigation = true;
  });

  // Attach the event submit for all forms in the page
  $("form").bind("submit", function() {
     validNavigation = true;
  });

A global variable is defined at page level. If this variable is not set to true then the event windows.onbeforeonload will terminate the session.

An event handler is attached to every link and form in the page to set this variable to true, thus preventing the session from being terminated if the user is just submitting a form or clicking on a link.

function endSession() {
   $.get("<whatever url will end your session>");
}

The session is terminated if the user closed the browser/tab or navigated away. In this case the global variable was not set to true and the script will do an AJAX call to whichever URL you want to end the session

This solution is server-side technology agnostic. It was not exaustively tested but it seems to work fine in my tests

changing the SVG file was not a fair solution for me so instead, I used relative CSS units.

vh, vw, % are very handy. I used a CSS like height: 2.4vh; to set a dynamic size to my SVG images.

You can try this simple way for combining columns:

select some_other_column,first_name || ' ' || last_name AS First_name from customer;

Let Spring 3 injection take care of this.

Thanks to tsunade21 the easiest way is:

 @RequestMapping(method = RequestMethod.GET)   
 public ModelAndView anyMethodNameGoesHere(Principal principal) {
        final String loggedInUserName = principal.getName();

 }

Mutable default arguments don't generally do what you want. Instead, try this:

class Node:
     def __init__(self, wordList=None, adjacencyList=None):
        if wordList is None:
            self.wordList = []
        else:
             self.wordList = wordList 
        if adjacencyList is None:
            self.adjacencyList = []
        else:
             self.adjacencyList = adjacencyList 

CHARINDEX will return 0 if no spaces are in the string and then you look for a substring of -1 length.

You can tack a trailing space on to the end of the string to ensure there is always at least one space and avoid this problem.

SELECT SUBSTRING(PostCode, 1 , CHARINDEX(' ', PostCode + ' ' ) -1)

One way, provide --user flag as part of curl, as follows:

curl --user username:password http://example.com

Another way is to get Base64 encoded token of "username:password" from any online website like - https://www.base64encode.org/ and pass it as Authorization header of curl as follows:

curl -i -H 'Authorization:Basic dXNlcm5hbWU6cGFzc3dvcmQ=' http://localhost:8080/

Here, dXNlcm5hbWU6cGFzc3dvcmQ= is Base64 encoded token of username:password.

Just super(); alone will call the default constructor, if it exists of a class's superclass. But you must explicitly write the default constructor yourself. If you don't a Java will generate one for you with no implementations, save super(); , referring to the universal Superclass Object, and you can't call it in a subclass.

public class Alien{
   public Alien(){ //Default constructor is written out by user
   /** Implementation not shown…**/
   }
}

public class WeirdAlien extends Alien{
   public WeirdAlien(){
   super(); //calls the default constructor in Alien.
   }

}

it works like scribd

__all__ affects how from foo import * works.

Code that is inside a module body (but not in the body of a function or class) may use an asterisk (*) in a from statement:

from foo import *

The * requests that all attributes of module foo (except those beginning with underscores) be bound as global variables in the importing module. When foo has an attribute __all__, the attribute's value is the list of the names that are bound by this type of from statement.

If foo is a package and its __init__.py defines a list named __all__, it is taken to be the list of submodule names that should be imported when from foo import * is encountered. If __all__ is not defined, the statement from foo import * imports whatever names are defined in the package. This includes any names defined (and submodules explicitly loaded) by __init__.py.

Note that __all__ doesn't have to be a list. As per the documentation on the import statement, if defined, __all__ must be a sequence of strings which are names defined or imported by the module. So you may as well use a tuple to save some memory and CPU cycles. Just don't forget a comma in case the module defines a single public name:

__all__ = ('some_name',)

You can't convert binary data to String. As a solution you can encode binary data and then convert to String. For example, look at this How do you convert binary data to Strings and back in Java?

You can return empty array by following two ways:

If you want to return array of int then

1. Using {}:

   int arr[] = {};
   return arr;
   

2. Using new int[0]:

   int arr[] = new int[0];
   return arr;
   

Same way you can return array for other datatypes as well.

 static void Main()
    {
        // A.
        // Example strings with multiple whitespaces.
        string s1 = "He saw   a cute\tdog.";
        string s2 = "There\n\twas another sentence.";

        // B.
        // Create the Regex.
        Regex r = new Regex(@"\s+");

        // C.
        // Strip multiple spaces.
        string s3 = r.Replace(s1, @" ");
        Console.WriteLine(s3);

        // D.
        // Strip multiple spaces.
        string s4 = r.Replace(s2, @" ");
        Console.WriteLine(s4);
        Console.ReadLine();
    }

OUTPUT:

He saw a cute dog. There was another sentence. He saw a cute dog.

No need for a StringBuilder:

string path = @"c:\hereIAm.txt";
if (!File.Exists(path)) 
{
    // Create a file to write to.
    using (StreamWriter sw = File.CreateText(path)) 
    {
        sw.WriteLine("Here");
        sw.WriteLine("I");
        sw.WriteLine("am.");
    }    
} 

But of course you can use the StringBuilder to create all lines and write them to the file at once.

sw.Write(stringBuilder.ToString());

FORMAT() is slower than CONVERT(). This answer is slightly better than @jpx's answer because it only does a replace on the time part of the date.

112 = yyyymmdd - no format change needed

108 = hh:mm:ss - remove :

SELECT CONVERT(VARCHAR, GETDATE(), 112) + 
       REPLACE(CONVERT(VARCHAR, GETDATE(), 108), ':', '')

An alternative, is install the unused package you want to delete in any project of your solution, after that, uninstall it and Nuget will remove it too.

A proper uninstaller is needed here.

Probably your best bet with this kind of scenario is to use jQuery's change method to find the currently selected value, like so:

$('#aioConceptName').change(function(){

   //get the selected val using jQuery's 'this' method and assign to a var
   var selectedVal = $(this).val();

   //perform the rest of your operations using aforementioned var

});

I prefer this method because you can then perform functions for each selected option in a given select field.

Hope that helps!

Quick fix for the issue described by @Malachiasz

I've fixed the issue by adding custom support for this in the auto resize class:

public void setTextCompat(final CharSequence text) {
    setTextCompat(text, BufferType.NORMAL);
}

public void setTextCompat(final CharSequence text, BufferType type) {
    // Quick fix for Android Honeycomb and Ice Cream Sandwich which sets the text only on the first call
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB_MR1 &&
        Build.VERSION.SDK_INT <= Build.VERSION_CODES.ICE_CREAM_SANDWICH_MR1) {
        super.setText(DOUBLE_BYTE_WORDJOINER + text + DOUBLE_BYTE_WORDJOINER, type);
    } else {
        super.setText(text, type);
    }
}

@Override
public CharSequence getText() {
    String originalText = super.getText().toString();
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB_MR1 &&
        Build.VERSION.SDK_INT <= Build.VERSION_CODES.ICE_CREAM_SANDWICH_MR1) {
        // We try to remove the word joiners we added using compat method - if none found - this will do nothing.
        return originalText.replaceAll(DOUBLE_BYTE_WORDJOINER, "");
    } else {
        return originalText;
    }
}

Just call yourView.setTextCompat(newTextValue) instead of yourView.setText(newTextValue)

String int2string = Integer.toHexString(INTEGERColor); //to ARGB
String HtmlColor = "#"+ int2string.substring(int2string.length() - 6, int2string.length()); // a stupid way to append your color

I got the same error while using other one entity, He was annotating the class wrongly by using the table name inside the @Entity annotation without using the @Table annotation

The correct format should be

@Entity //default name similar to class name 'FooBar' OR @Entity( name = "foobar" ) for differnt entity name
@Table( name = "foobar" ) // Table name 
public class FooBar{

  <input attr1='a' attr2='b' attr3='c'>foo</input>

getAttribute(attr1) you get 'a'

getAttribute(attr2) you get 'b'

getAttribute(attr3) you get 'c'

getText() with no parameter you can only get 'foo'

The 2 main reason why you might want to prefer Mongo are

• Flexibility in schema design (JSON type document store).
• Scalability - Just add up nodes and it can scale horizontally quite well.

It is suitable for big data applications. RDBMS is not good for big data.

Cross join and inner join are the same with the only difference that in inner join we booleanly filter some of the outcomes of the cartesian product

table1
x--------------------------------------x
|  fieldA  |    fieldB   |    fieldC   | 
x----------|-------------|-------------x            
|    A     |      B      |    option1  |
|    A     |      B1     |    option2  |
x--------------------------------------x

table2
x--------------------------------------x
|  fieldA  |    fieldB   |    fieldC   | 
x----------|-------------|-------------x            
|    A     |      B      |    optionB1 |
|    A1    |      B1     |    optionB2 |
x--------------------------------------x

 cross join
  A,B,option1,A,B,optionB1
  A,B,option1,A1,B1,optionB2
  A,B1,option2,A,B,optionB1
  A,B1,option2,A1,B1,optionB2

 inner join on field1 (only with the value is the same in both tables)
  A,B,option1,A,B,optionB1
  A,B1,option2,A,B,optionB1

 inner join on field1
  A,B,option1,A,B,optionB1

It is on design of our data where we decide that there is only one case of the field we are using for the join. Join only cross join both tables and get only the lines accomplishing special boolean expression.

Note that if the fields we are doing our Joins on would be null in both tables we would pass the filter. It is up to us or the database manufacturer to add extra rules to avoid or permit nulls. Adhering to the basics it is just a cross join followed by a filter.

Portability between Linux and Windows is a big headache, since Linux is a POSIX-conformant system with - generally - a proper, high quality toolchain for C, whereas Windows doesn't even provide a lot of functions in the C standard library.

However, if you want to stick to the standard, you can write something like this:

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

FILE *f = fopen("textfile.txt", "rb");
fseek(f, 0, SEEK_END);
long fsize = ftell(f);
fseek(f, 0, SEEK_SET);  /* same as rewind(f); */

char *string = malloc(fsize + 1);
fread(string, 1, fsize, f);
fclose(f);

string[fsize] = 0;

Here string will contain the contents of the text file as a properly 0-terminated C string. This code is just standard C, it's not POSIX-specific (although that it doesn't guarantee it will work/compile on Windows...)

It is not quite clear what function you are talking about and if you need 2 separate branches or one. Assuming one:

Change your first line to

$slide = '';
if (isset($_GET["id"]))
{
    $slide = $_GET["id"];
}

(In Kotlin) If you are going to put the answer into a TextView or something you can instead use a string resource:

<string name="time">%02d:%02d</string>

And then you can use this String resource to then set the text at run time using:

private fun setTime(time: Int) {
    val hour = time / 60
    val min = time % 60
    main_time.text = getString(R.string.time, hour, min)
}

you can user canvans with jsPDF

import jsPDF from 'jspdf';
import html2canvas from 'html2canvas';

 _exportPdf = () => {

     html2canvas(document.querySelector("#capture")).then(canvas => {
        document.body.appendChild(canvas);  // if you want see your screenshot in body.
        const imgData = canvas.toDataURL('image/png');
        const pdf = new jsPDF();
        pdf.addImage(imgData, 'PNG', 0, 0);
        pdf.save("download.pdf"); 
    });

 }

and you div with id capture is:

example

<div id="capture">
  <p>Hello in my life</p>
  <span>How can hellp you</span>
</div>

If you just want to insert a value at a certain position in a string, you can use the String.Insert method:

public string Insert(int startIndex, string value)

Example:

"abc".Insert(2, "XYZ") == "abXYZc"

If it's installed with homebrew try just typing down mysql.server in terminal and that should be it. AFAIK it executable will be under /usr/local/bin/mysql.server.

If not you can always run following "locate mysql.server" which will tell you where to find such file.

If you don't want to use jQuery

<form enctype='multipart/form-data'>
    <input onchange="alert(this.value); return false;" type='file'>
    <br>
    <input type='submit' value='Upload'>
</form>

It works fine in Firefox, but for Chrome you need to add this.value=null; after alert.

You don't have to change style for it. After setting up your toolbar as actionbar, You can code like this

android.getSupportActionBar().setDisplayHomeAsUpEnabled(true);
android.getSupportActionBar().setHomeAsUpIndicator(R.drawable.back);
//here back is your drawable image

But You cannot change color of back arrow by this method

You can combine the two functions; coerce to characters thence to numerics:

> fac <- factor(c("1","2","1","2"))
> as.numeric(as.character(fac))
[1] 1 2 1 2

This works for me to access the class attribute (on beautifulsoup 4, contrary to what the documentation says). The KeyError comes a list being returned not a dictionary.

for hit in soup.findAll(name='span'):
    print hit.contents[1]['class']

For me, it worked once I changed

Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");

to:

in POM

<dependency>
    <groupId>com.microsoft.sqlserver</groupId>
    <artifactId>mssql-jdbc</artifactId>
    <version>6.1.0.jre8</version>
</dependency>

and then:

import com.microsoft.sqlserver.jdbc.SQLServerDriver;

...

DriverManager.registerDriver(SQLServerDriver());    
Connection connection = DriverManager.getConnection(connectionUrl); 

You can subset using a vector of column names. I strongly prefer this approach over those that treat column names as if they are object names (e.g. subset()), especially when programming in functions, packages, or applications.

# data for reproducible example
# (and to avoid confusion from trying to subset `stats::df`)
df <- setNames(data.frame(as.list(1:5)), LETTERS[1:5])
# subset
df[c("A","B","E")]

Note there's no comma (i.e. it's not df[,c("A","B","C")]). That's because df[,"A"] returns a vector, not a data frame. But df["A"] will always return a data frame.

str(df["A"])
## 'data.frame':    1 obs. of  1 variable:
## $ A: int 1
str(df[,"A"])  # vector
##  int 1

Thanks to David Dorchies for pointing out that df[,"A"] returns a vector instead of a data.frame, and to Antoine Fabri for suggesting a better alternative (above) to my original solution (below).

# subset (original solution--not recommended)
df[,c("A","B","E")]  # returns a data.frame
df[,"A"]             # returns a vector

Where is it pushed on?

esp - 4. More precisely:

• esp gets subtracted by 4
• the value is pushed to esp

pop reverses this.

The System V ABI tells Linux to make rsp point to a sensible stack location when the program starts running: What is default register state when program launches (asm, linux)? which is what you should usually use.

How can you push a register?

Minimal GNU GAS example:

.data
    /* .long takes 4 bytes each. */
    val1:
        /* Store bytes 0x 01 00 00 00 here. */
        .long 1
    val2:
        /* 0x 02 00 00 00 */
        .long 2
.text
    /* Make esp point to the address of val2.
     * Unusual, but totally possible. */
    mov $val2, %esp

    /* eax = 3 */
    mov $3, %ea 

    push %eax
    /*
    Outcome:
    - esp == val1
    - val1 == 3
    esp was changed to point to val1,
    and then val1 was modified.
    */

    pop %ebx
    /*
    Outcome:
    - esp == &val2
    - ebx == 3
    Inverses push: ebx gets the value of val1 (first)
    and then esp is increased back to point to val2.
    */

The above on GitHub with runnable assertions.

Why is this needed?

It is true that those instructions could be easily implemented via mov, add and sub.

They reason they exist, is that those combinations of instructions are so frequent, that Intel decided to provide them for us.

The reason why those combinations are so frequent, is that they make it easy to save and restore the values of registers to memory temporarily so they don't get overwritten.

To understand the problem, try compiling some C code by hand.

A major difficulty, is to decide where each variable will be stored.

Ideally, all variables would fit into registers, which is the fastest memory to access (currently about 100x faster than RAM).

But of course, we can easily have more variables than registers, specially for the arguments of nested functions, so the only solution is to write to memory.

We could write to any memory address, but since the local variables and arguments of function calls and returns fit into a nice stack pattern, which prevents memory fragmentation, that is the best way to deal with it. Compare that with the insanity of writing a heap allocator.

Then we let compilers optimize the register allocation for us, since that is NP complete, and one of the hardest parts of writing a compiler. This problem is called register allocation, and it is isomorphic to graph coloring.

When the compiler's allocator is forced to store things in memory instead of just registers, that is known as a spill.

Does this boil down to a single processor instruction or is it more complex?

All we know for sure is that Intel documents a push and a pop instruction, so they are one instruction in that sense.

Internally, it could be expanded to multiple microcodes, one to modify esp and one to do the memory IO, and take multiple cycles.

But it is also possible that a single push is faster than an equivalent combination of other instructions, since it is more specific.

This is mostly un(der)documented:

• Peter Cordes mentions that techniques described at http://agner.org/optimize/microarchitecture.pdf suggest that push and pop take one single micro operation.
• Johan mentions that since the Pentium M Intel uses a "stack engine", which stores precomputed esp+regsize and esp-regsize values, allowing push and pop to execute in a single uop. Also mentioned at: https://en.wikipedia.org/wiki/Stack_register
• What is Intel microcode?
• https://security.stackexchange.com/questions/29730/processor-microcode-manipulation-to-change-opcodes
• How many CPU cycles are needed for each assembly instruction?

There is a simple method for deleting selected items, and all these people are going for a hard method:

lstYOURVARIABLE.Items.Remove(lstYOURVARIABLE.SelectedItem)

I used this in Visual Basic mode on Visual Studio.

All HIVE managed tables are stored in the below HDFS location.

hadoop fs -ls /user/hive/warehouse/databasename.db/tablename

The easiest way to find the best fit in R is to code the model as:

lm.1 <- lm(y ~ x + I(x^2) + I(x^3) + I(x^4) + ...)

After using step down AIC regression

lm.s <- step(lm.1)

There is one tricky scenario. If I am looking for '40' in the list '17,34,400,12' then it would find ",40" and return that incorrect entry. This takes care of all solutions:

WHERE (',' + RTRIM(MyColumn) + ',') LIKE '%,' + @search + ',%'

This seems like an XML problem. Open the XML document containing your Web-View. Delete the padding code at the top.

Then in the layout , add

android:layout_width="fill_parent"
android:layout_height="fill_parent"

In the Web-View, add

android:layout_width="fill_parent"
android:layout_height="fill_parent" 

This makes the Web-View fit the device screen.

I know this is an old question, but I found a better solution with Vue.js 2.0+ Custom Directives: I needed to bind the scroll event too, then I implemented this.

First of, using @vue/cli, add the custom directive to src/main.js (before the Vue.js instance) or wherever you initiate it:

Vue.directive('scroll', {
  inserted: function(el, binding) {
    let f = function(evt) {
      if (binding.value(evt, el)) {
        window.removeEventListener('scroll', f);
      }
    }
    window.addEventListener('scroll', f);
  }
});

Then, add the custom v-scroll directive to the element and/or the component you want to bind on. Of course you have to insert a dedicated method: I used handleScroll in my example.

<my-component v-scroll="handleScroll"></my-component>

Last, add your method to the component.

methods: {
  handleScroll: function() {
    // your logic here
  }
}

You don’t have to care about the Vue.js lifecycle anymore here, because the custom directive itself does.

On linux, you can run this command and see the result :

ps aux | grep "java"

To avoid SQL Injection with varchar parameters you could use

function sqlExecuteRead($connectionString, $sqlCommand, $pars) {

    $connection = new-object system.data.SqlClient.SQLConnection($connectionString)
    $connection.Open()
    $command = new-object system.data.sqlclient.sqlcommand($sqlCommand, $connection)

    if ($pars -and $pars.Keys) {

Remember before you merge you need to update the tag, it's quite different from branches (git pull origin tag_name won't update your local tags). Thus, you need the following command:

git fetch --tags origin

Then you can perform git merge tag_name to merge the tag onto a branch.

Lexical Analyzer takes a sequence of characters identifies a lexeme that matches the regular expression and further categorizes it to token. Thus, a Lexeme is matched string and a Token name is the category of that lexeme.

For example, consider below regular expression for an identifier with input "int foo, bar;"

letter(letter|digit|_)*

Here, foo and bar match the regular expression thus are both lexemes but are categorized as one token ID i.e identifier.

Also note, next phase i.e syntax analyzer need not have to know about lexeme but a token.

The function datepicker is case sensitive and all lowercase. The following however works fine for me:

$(document).ready(function() {
  $('.date-pick').datepicker( {
    onSelect: function(date) {
        alert(date);
    },
    selectWeek: true,
    inline: true,
    startDate: '01/01/2000',
    firstDay: 1
  });
});

The first line of a paragraph is indented by default, thus whether or not you have \indent there won't make a difference. \indent and \noindent can be used to override default behavior. You can see this by replacing your line with the following:

Now we are engaged in a great civil war.\\
\indent this is indented\\
this isn't indented


\noindent override default indentation (not indented)\\
asdf 

They are the same (as is the third form, ^=).

Note, though, that they are still considered different from the point of view of the parser, that is a stored outline defined for a != won't match <> or ^=.

This is unlike PostgreSQL where the parser treats != and <> yet on parsing stage, so you cannot overload != and <> to be different operators.

Array in swift is written as **Array < Element > **, where Element is the type of values the array is allowed to store.

Array can be initialized as :

let emptyArray = [String]()

It shows that its an array of type string

The type of the emptyArray variable is inferred to be [String] from the type of the initializer.

For Creating the array of type string with elements

var groceryList: [String] = ["Eggs", "Milk"]

groceryList has been initialized with two items

The groceryList variable is declared as “an array of string values”, written as [String]. This particular array has specified a value type of String, it is allowed to store String values only.

There are various properities of array like :

- To check if array has elements (If array is empty or not)

isEmpty property( Boolean ) for checking whether the count property is equal to 0:

if groceryList.isEmpty {
    print("The groceryList list is empty.")
} else {
    print("The groceryList is not empty.")
}

- Appending(adding) elements in array

You can add a new item to the end of an array by calling the array’s append(_:) method:

groceryList.append("Flour")

groceryList now contains 3 items.

Alternatively, append an array of one or more compatible items with the addition assignment operator (+=):

groceryList += ["Baking Powder"]

groceryList now contains 4 items

groceryList += ["Chocolate Spread", "Cheese", "Peanut Butter"]

groceryList now contains 7 items

Set the Maximise property to False.

First you need to get a token from android and then you can call this php code and you can even send data for further actions in your app.

 <?php

// Call .php?Action=M&t=title&m=message&r=token
$action=$_GET["Action"];


switch ($action) {
    Case "M":
         $r=$_GET["r"];
        $t=$_GET["t"];
        $m=$_GET["m"];

        $j=json_decode(notify($r, $t, $m));

        $succ=0;
        $fail=0;

        $succ=$j->{'success'};
        $fail=$j->{'failure'};

        print "Success: " . $succ . "<br>";
        print "Fail   : " . $fail . "<br>";

        break;


default:
        print json_encode ("Error: Function not defined ->" . $action);
}

function notify ($r, $t, $m)

HTTP Post data doesn't have a specified limit on the amount of data, where as different browsers have different limits for GET's. The RFC 2068 states:

Servers should be cautious about depending on URI lengths above 255 bytes, because some older client or proxy implementations may not properly support these lengths

Specifically you should the right HTTP constructs for what they're used for. HTTP GET's shouldn't have side-effects and can be safely refreshed and stored by HTTP Proxies, etc.

HTTP POST's are used when you want to submit data against a url resource.

A typical example for using HTTP GET is on a Search, i.e. Search?Query=my+query A typical example for using a HTTP POST is submitting feedback to an online form.

x^y is not "x to the power of y". It's "x XOR y".

I went round and round on this and it turned out to be improperly set default page. Hope this helps someone else avoid an hour of wasted time.

Instead of handling the focus enter and focus leave events in order to set and remove the placeholder text it is possible to use the Windows SendMessage function to send EM_SETCUEBANNER message to our textbox to do the work for us.

This can be done with two easy steps. First we need to expose the Windows SendMessage function.

private const int EM_SETCUEBANNER = 0x1501;

[DllImport("user32.dll", CharSet = CharSet.Auto)]
private static extern Int32 SendMessage(IntPtr hWnd, int msg, int wParam, [MarshalAs(UnmanagedType.LPWStr)]string lParam);

Then simply call the method with the handle of our textbox, EM_SETCUEBANNER’s value and the text we want to set.

SendMessage(textBox1.Handle, EM_SETCUEBANNER, 0, "Username");
SendMessage(textBox2.Handle, EM_SETCUEBANNER, 0, "Password");

Reference: Set placeholder text for textbox (cue text)

Both codes are only relevant when the phone runs out of memory and kills the service before it finishes executing. START_STICKY tells the OS to recreate the service after it has enough memory and call onStartCommand() again with a null intent. START_NOT_STICKY tells the OS to not bother recreating the service again. There is also a third code START_REDELIVER_INTENT that tells the OS to recreate the service and redeliver the same intent to onStartCommand().

This article by Dianne Hackborn explained the background of this a lot better than the official documentation.

Source: http://android-developers.blogspot.com.au/2010/02/service-api-changes-starting-with.html

The key part here is a new result code returned by the function, telling the system what it should do with the service if its process is killed while it is running:

START_STICKY is basically the same as the previous behavior, where the service is left "started" and will later be restarted by the system. The only difference from previous versions of the platform is that it if it gets restarted because its process is killed, onStartCommand() will be called on the next instance of the service with a null Intent instead of not being called at all. Services that use this mode should always check for this case and deal with it appropriately.

START_NOT_STICKY says that, after returning from onStartCreated(), if the process is killed with no remaining start commands to deliver, then the service will be stopped instead of restarted. This makes a lot more sense for services that are intended to only run while executing commands sent to them. For example, a service may be started every 15 minutes from an alarm to poll some network state. If it gets killed while doing that work, it would be best to just let it be stopped and get started the next time the alarm fires.

START_REDELIVER_INTENT is like START_NOT_STICKY, except if the service's process is killed before it calls stopSelf() for a given intent, that intent will be re-delivered to it until it completes (unless after some number of more tries it still can't complete, at which point the system gives up). This is useful for services that are receiving commands of work to do, and want to make sure they do eventually complete the work for each command sent.

In current releases of nmap you can use:

sudo nmap -sn 192.168.0.*

This will print the MAC addresses of all available hosts. Of course provide your own network, subnet and host id's.

Further explanation can be found here.

If you have a preference for Java 8 streams as your coding style then this can be achieved using just JDK primitives.

String hex = "0001027f80fdfeff";

byte[] converted = IntStream.range(0, hex.length() / 2)
    .map(i -> Character.digit(hex.charAt(i * 2), 16) << 4 | Character.digit(hex.charAt((i * 2) + 1), 16))
    .collect(ByteArrayOutputStream::new,
             ByteArrayOutputStream::write,
             (s1, s2) -> s1.write(s2.toByteArray(), 0, s2.size()))
    .toByteArray();

The , 0, s2.size() parameters in the collector concatenate function can be omitted if you don't mind catching IOException.

use below code , change proper database name and user name and then take that output and execute in SSMS. FOR SQL 2005 ABOVE

USE <database_name> 
select 'GRANT EXECUTE ON ['+name+'] TO [userName]  '  
from sys.objects  
where type ='P' 
and is_ms_shipped = 0  

I found $.String.deparam the most complete pre built solution (can do nested objects etc.). Check out the documentation.

grep command can be used

CA = mydata[grep("CA", mydata$sCode, ]

nrow(CA)

There are two possibilities to use if condition on HTML tag or templates:

1. *ngIf directive from CommonModule, on HTML tag;
2. if-else

I asked this a while back. The answer is basically that it doesn't work. :(

DateAdd(m,1,reference_dt)

will add a month to the column value

I assume this code has concurrency issues:

Actually, it's quite possibly fine, though with a possible improvement.

Now, in general the pattern where we have multiple threads setting a shared value on first use, to not lock on the value being obtained and set can be:

1. Disastrous - other code will assume only one instance exists.
2. Disastrous - the code that obtains the instance is not can only tolerate one (or perhaps a certain small number) concurrent operations.
3. Disastrous - the means of storage is not thread-safe (e.g. have two threads adding to a dictionary and you can get all sorts of nasty errors).
4. Sub-optimal - the overall performance is worse than if locking had ensured only one thread did the work of obtaining the value.
5. Optimal - the cost of having multiple threads do redundant work is less than the cost of preventing it, especially since that can only happen during a relatively brief period.

However, considering here that MemoryCache may evict entries then:

1. If it's disastrous to have more than one instance then MemoryCache is the wrong approach.
2. If you must prevent simultaneous creation, you should do so at the point of creation.
3. MemoryCache is thread-safe in terms of access to that object, so that is not a concern here.

Both of these possibilities have to be thought about of course, though the only time having two instances of the same string existing can be a problem is if you're doing very particular optimisations that don't apply here*.

So, we're left with the possibilities:

1. It is cheaper to avoid the cost of duplicate calls to SomeHeavyAndExpensiveCalculation().
2. It is cheaper not to avoid the cost of duplicate calls to SomeHeavyAndExpensiveCalculation().

And working that out can be difficult (indeed, the sort of thing where it's worth profiling rather than assuming you can work it out). It's worth considering here though that most obvious ways of locking on insert will prevent all additions to the cache, including those that are unrelated.

This means that if we had 50 threads trying to set 50 different values, then we'll have to make all 50 threads wait on each other, even though they weren't even going to do the same calculation.

As such, you're probably better off with the code you have, than with code that avoids the race-condition, and if the race-condition is a problem, you quite likely either need to handle that somewhere else, or need a different caching strategy than one that expels old entries†.

The one thing I would change is I'd replace the call to Set() with one to AddOrGetExisting(). From the above it should be clear that it probably isn't necessary, but it would allow the newly obtained item to be collected, reducing overall memory use and allowing a higher ratio of low generation to high generation collections.

So yeah, you could use double-locking to prevent concurrency, but either the concurrency isn't actually a problem, or your storing the values in the wrong way, or double-locking on the store would not be the best way to solve it.

*If you know only one each of a set of strings exists, you can optimise equality comparisons, which is about the only time having two copies of a string can be incorrect rather than just sub-optimal, but you'd want to be doing very different types of caching for that to make sense. E.g. the sort XmlReader does internally.

†Quite likely either one that stores indefinitely, or one that makes use of weak references so it will only expel entries if there are no existing uses.

This is older but placing this here for my reference too. boto3.resource is just implementing the default Session, you can pass through boto3.resource session details.

Help on function resource in module boto3:

resource(*args, **kwargs)
    Create a resource service client by name using the default session.

    See :py:meth:`boto3.session.Session.resource`.

https://github.com/boto/boto3/blob/86392b5ca26da57ce6a776365a52d3cab8487d60/boto3/session.py#L265

you can see that it just takes the same arguments as Boto3.Session

import boto3
S3 = boto3.resource('s3', region_name='us-west-2', aws_access_key_id=settings.AWS_SERVER_PUBLIC_KEY, aws_secret_access_key=settings.AWS_SERVER_SECRET_KEY)
S3.Object( bucket_name, key_name ).delete()

I found the blog on random search, i think this will help for doing this: http://tomjefferys.blogspot.com.tr/2011/09/multimaps-google-guava.html

public class MutliMapTest {
public static void main(String... args) {
   Multimap<String, String> myMultimap = ArrayListMultimap.create();

   // Adding some key/value
   myMultimap.put("Fruits", "Bannana");
   myMultimap.put("Fruits", "Apple");
   myMultimap.put("Fruits", "Pear");
   myMultimap.put("Vegetables", "Carrot");

   // Getting the size
   int size = myMultimap.size();
   System.out.println(size);  // 4

   // Getting values
   Collection<String> fruits = myMultimap.get("Fruits");
   System.out.println(fruits); // [Bannana, Apple, Pear]

   Collection<string> vegetables = myMultimap.get("Vegetables");
   System.out.println(vegetables); // [Carrot]

   // Iterating over entire Mutlimap
   for(String value : myMultimap.values()) {
      System.out.println(value);
   }

   // Removing a single value
   myMultimap.remove("Fruits","Pear");
   System.out.println(myMultimap.get("Fruits")); // [Bannana, Pear]

   // Remove all values for a key
   myMultimap.removeAll("Fruits");
   System.out.println(myMultimap.get("Fruits")); // [] (Empty Collection!)
}
}

Another useful time to include @ is when you use FOR in the command line. For example:

FOR %F IN (*.*) DO ECHO %F

Previous line show for every file: the command prompt, the ECHO command, and the result of ECHO command. This way:

FOR %F IN (*.*) DO @ECHO %F

Just the result of ECHO command is shown.

Do I really have to first convert it into an array of arrays of key-value pairs?

No, an iterator of key-value pair arrays is enough. You can use the following to avoid creating the intermediate array:

function* entries(obj) {
    for (let key in obj)
        yield [key, obj[key]];
}

const map = new Map(entries({foo: 'bar'}));
map.get('foo'); // 'bar'

No need to re-assign.

a=[]
for i in range(5):    
    a.append(i)
a

Create a class and put all your code in there and call an instance of this class from the Main :

static void Main(string[] args)
{

    MyClass cls  = new MyClass();
    Console.Write("Write a number: ");
    long a= Convert.ToInt64(Console.ReadLine()); // a is the number given by the user
    long av = cls.volteado(a);
    bool isTrue = cls.siprimo(a);
    ......etc

}

In my case I was using the maven-dependency-plugin so in order to resolve the issue I had to add the following property:

  <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

See Apache Maven Resources Plugin / Specifying a character encoding scheme

instead of using add() we can use addall()

{ seeAlso.addall(groupDn); }

add adds a single item, while addAll adds each item from the collection one by one. In the end, both methods return true if the collection has been modified. In case of ArrayList this is trivial, because the collection is always modified, but other collections, such as Set, may return false if items being added are already there.

JAVA HOME is used for setting up the environment variable for JAVA. It means that you are providing a path for compiling a JAVA program and also running the same. So, if you do not set the JAVA HOME( PATH ) and try to run a java or any dependent program in the command prompt.

You will deal with an error as javac : not recognized as internal or external command. Now to set this, Just open your Java jdk then open bin folder then copy the PATH of that bin folder.

Now, go to My computer right click on it----> select properties-----> select Advanced system settings----->Click on Environment Variables------>select New----->give a name in the text box Variable Name and then paste the path in Value.

That's All!!

It's safe to increase the size of your varchar column. You won't corrupt your data.

If it helps your peace of mind, keep in mind, you can always run a database backup before altering your data structures.

By the way, correct syntax is:

ALTER TABLE table_name MODIFY col_name VARCHAR(10000)

Also, if the column previously allowed/did not allow nulls, you should add the appropriate syntax to the end of the alter table statement, after the column type.

Use the json module to produce JSON output:

import json

with open(outputfilename, 'wb') as outfile:
    json.dump(row, outfile)

This writes the JSON result directly to the file (replacing any previous content if the file already existed).

If you need the JSON result string in Python itself, use json.dumps() (added s, for 'string'):

json_string = json.dumps(row)

The L is just Python syntax for a long integer value; the json library knows how to handle those values, no L will be written.

Demo string output:

>>> import json
>>> row = [1L,[0.1,0.2],[[1234L,1],[134L,2]]]
>>> json.dumps(row)
'[1, [0.1, 0.2], [[1234, 1], [134, 2]]]'

If you're behind a proxy, you should use X-Forwarded-For: http://en.wikipedia.org/wiki/X-Forwarded-For

It is an IETF draft standard with wide support:

The X-Forwarded-For field is supported by most proxy servers, including Squid, Apache mod_proxy, Pound, HAProxy, Varnish cache, IronPort Web Security Appliance, AVANU WebMux, ArrayNetworks, Radware's AppDirector and Alteon ADC, ADC-VX, and ADC-VA, F5 Big-IP, Blue Coat ProxySG, Cisco Cache Engine, McAfee Web Gateway, Phion Airlock, Finjan's Vital Security, NetApp NetCache, jetNEXUS, Crescendo Networks' Maestro, Web Adjuster and Websense Web Security Gateway.

If not, here are a couple other common headers I've seen:

• X-Client-IP (Apache)
• X-Real-IP (Nginx)

1. Make sure you have System.Web referenced
2. Get rid of the two } at the end.

you can disable all selection

.disable-all{-webkit-touch-callout: none;  -webkit-user-select: none;-khtml-user-select: none;-moz-user-select: none;-ms-user-select: none;user-select: none;}

now you can enable input and text-area enable

input, textarea{
-webkit-touch-callout:default;
-webkit-user-select:text;
-khtml-user-select: text;
-moz-user-select:text;
-ms-user-select:text;
user-select:text;}

You can use

SELECT SYS_EXTRACT_UTC(TIMESTAMP '2000-03-28 11:30:00.00 -02:00') FROM DUAL;

You may also need to change your timezone

ALTER SESSION SET TIME_ZONE = 'Europe/Berlin';

Or read it

SELECT SESSIONTIMEZONE, CURRENT_TIMESTAMP FROM dual;

You can use class loader which will read from classpath as ROOT path (without "/" in the beginning)

InputStream in = getClass().getClassLoader().getResourceAsStream("file.txt"); 
BufferedReader reader = new BufferedReader(new InputStreamReader(in));

If you're trying to print a specific register in GDB, you have to omit the % sign. For example,

info registers eip

If your executable is 64 bit, the registers start with r. Starting them with e is not valid.

info registers rip

Those can be abbreviated to:

i r rip

This shell command prints the output format in csv to output.txt without the column headers.

$ hive --outputformat=csv2 -f 'hivedatascript.hql' --hiveconf hive.cli.print.header=false > output.txt

just use a Button with android:drawableRight properties like this:

<Button android:id="@+id/btnNovaCompra" android:layout_width="wrap_content"
        android:text="@string/btn_novaCompra"
        android:gravity="center"
        android:drawableRight="@drawable/shoppingcart"
        android:layout_height="wrap_content"/>

probably the onclick handler should read onclick='hello();' instead of onclick=hello();

.style1 {
  background: url(images/bg.jpg) no-repeat center center fixed;
  -webkit-background-size: cover;
  -moz-background-size: cover;
  -o-background-size: cover;
  background-size: cover;
}

Works in:

• Safari 3+
• Chrome Whatever+
• IE 9+
• Opera 10+ (Opera 9.5 supported background-size but not the keywords)
• Firefox 3.6+ (Firefox 4 supports non-vendor prefixed version)

In addition you can try this for an IE solution

filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(src='.myBackground.jpg', sizingMethod='scale');
-ms-filter: "progid:DXImageTransform.Microsoft.AlphaImageLoader(src='myBackground.jpg', sizingMethod='scale')";
zoom: 1;

In ASP.Net Core anti forgery token is automatically added to forms, so you don't need to add @Html.AntiForgeryToken() if you use razor form element or if you use IHtmlHelper.BeginForm and if the form's method isn't GET.

It will generate input element for your form similar to this:

<input name="__RequestVerificationToken" type="hidden" 
       value="CfDJ8HSQ_cdnkvBPo-jales205VCq9ISkg9BilG0VXAiNm3Fl5Lyu_JGpQDA4_CLNvty28w43AL8zjeR86fNALdsR3queTfAogif9ut-Zd-fwo8SAYuT0wmZ5eZUYClvpLfYm4LLIVy6VllbD54UxJ8W6FA">

And when user submits form this token is verified on server side if validation is enabled.

[ValidateAntiForgeryToken] attribute can be used against actions. Requests made to actions that have this filter applied are blocked unless the request includes a valid antiforgery token.

[AutoValidateAntiforgeryToken] attribute can be used against controllers. This attribute works identically to the ValidateAntiForgeryToken attribute, except that it doesn't require tokens for requests made using the following HTTP methods: GET HEAD OPTIONS TRACE

Use a memory stream

using(MemoryStream ms = new MemoryStream())
{
    image.Save(ms, ...);
    return ms.ToArray();
}

J2ME Map Route Provider

maps.google.com has a navigation service which can provide you route information in KML format.

To get kml file we need to form url with start and destination locations:

public static String getUrl(double fromLat, double fromLon,
                            double toLat, double toLon) {// connect to map web service
    StringBuffer urlString = new StringBuffer();
    urlString.append("http://maps.google.com/maps?f=d&hl=en");
    urlString.append("&saddr=");// from
    urlString.append(Double.toString(fromLat));
    urlString.append(",");
    urlString.append(Double.toString(fromLon));
    urlString.append("&daddr=");// to
    urlString.append(Double.toString(toLat));
    urlString.append(",");
    urlString.append(Double.toString(toLon));
    urlString.append("&ie=UTF8&0&om=0&output=kml");
    return urlString.toString();
}

Next you will need to parse xml (implemented with SAXParser) and fill data structures:

public class Point {
    String mName;
    String mDescription;
    String mIconUrl;
    double mLatitude;
    double mLongitude;
}

public class Road {
    public String mName;
    public String mDescription;
    public int mColor;
    public int mWidth;
    public double[][] mRoute = new double[][] {};
    public Point[] mPoints = new Point[] {};
}

Network connection is implemented in different ways on Android and Blackberry, so you will have to first form url:

 public static String getUrl(double fromLat, double fromLon,
     double toLat, double toLon)

then create connection with this url and get InputStream.
Then pass this InputStream and get parsed data structure:

 public static Road getRoute(InputStream is)

I finally found out how to do this! Basically you need to run adb shell first and then while you're in the shell run su, which will switch the shell to run as root!

$: adb shell
$: su

The one problem I still have is that sqlite3 is not installed so the command is not recognized.

To make it easier add a custom function and call it when ever you want that changing the value also trigger change

$.fn.valAndTrigger = function (element) {
    return $(this).val(element).trigger('change');
}

and

$("#sample").valAndTirgger("NewValue");

Or you can override the val function to always call the change when the val is called

(function ($) {
    var originalVal = $.fn.val;
    $.fn.val = function (value) {
        this.trigger("change");
        return originalVal.call(this, value);
    };
})(jQuery);

Optimising @Don approach to use only One Query

SELECT * from (
  SELECT 
     @rownum:=@rownum+1 row,
     CASE a.id WHEN 'CurrentArticleID' THEN @currentrow:=@rownum ELSE NULL END as 'current_row',
     a.*  
  FROM articles a,
     (SELECT @currentrow:=0) c,  
     (SELECT @rownum:=0) r
   ORDER BY `date`, id  DESC
 ) as article_with_row
 where row > @currentrow - 2
 limit 3

change CurrentArticleID with current article ID like

SELECT * from (
  SELECT 
     @rownum:=@rownum+1 row,
     CASE a.id WHEN '100' THEN @currentrow:=@rownum ELSE NULL END as 'current_row',
     a.*  
  FROM articles a,
     (SELECT @currentrow:=0) c,  
     (SELECT @rownum:=0) r
   ORDER BY `date`, id  DESC
 ) as article_with_row
 where row > @currentrow - 2
 limit 3

Try %*s and %-*s and prefix each string with the column width:

>>> print "Location: %-*s  Revision: %s" % (20,"10-10-10-10","1")
Location: 10-10-10-10           Revision: 1
>>> print "District: %-*s  Date: %s" % (20,"Tower","May 16, 2012")
District: Tower                 Date: May 16, 2012

Simples

function time($block) {
    $sw = [Diagnostics.Stopwatch]::StartNew()
    &$block
    $sw.Stop()
    $sw.Elapsed
}

then can use as

time { .\some_command }

You may want to tweak the output

Of course you can use the StringTokenizer class to split the String with '.' or '/', and check if the last word is "work".

How's this for an explantation to the layman. One way computers represent numbers is by counting discrete units. These are digital computers. For whole numbers, those without a fractional part, modern digital computers count powers of two: 1, 2, 4, 8. ,,, Place value, binary digits, blah , blah, blah. For fractions, digital computers count inverse powers of two: 1/2, 1/4, 1/8, ... The problem is that many numbers can't be represented by a sum of a finite number of those inverse powers. Using more place values (more bits) will increase the precision of the representation of those 'problem' numbers, but never get it exactly because it only has a limited number of bits. Some numbers can't be represented with an infinite number of bits.

Snooze...

OK, you want to measure the volume of water in a container, and you only have 3 measuring cups: full cup, half cup, and quarter cup. After counting the last full cup, let's say there is one third of a cup remaining. Yet you can't measure that because it doesn't exactly fill any combination of available cups. It doesn't fill the half cup, and the overflow from the quarter cup is too small to fill anything. So you have an error - the difference between 1/3 and 1/4. This error is compounded when you combine it with errors from other measurements.

Here's an efficient way of achieving the result with two caveats.

1. Limits precision to 'maximum' N digits (not fixed to N digits).
2. Rounds down the number (not round to nearest).

See sample test cases here.

123.12345678 ==> 123.123
1.230000 ==> 1.23
1.1 ==> 1.1
1 ==> 1.0
0.000 ==> 0.0
0.00 ==> 0.0
0.4 ==> 0.4
0 ==> 0.0
1.4999 ==> 1.499
1.4995 ==> 1.499
1.4994 ==> 1.499

Here's the code. The two caveats I mentioned above can be addressed pretty easily, however, speed mattered more to me than accuracy, so i left it here. String manipulations like System.out.printf("%.2f",123.234); are computationally costly compared to mathematical operations. In my tests, the below code (without the sysout) took 1/30th the time compared to String manipulations.

public double limitPrecision(String dblAsString, int maxDigitsAfterDecimal) {
    int multiplier = (int) Math.pow(10, maxDigitsAfterDecimal);
    double truncated = (double) ((long) ((Double.parseDouble(dblAsString)) * multiplier)) / multiplier;
    System.out.println(dblAsString + " ==> " + truncated);
    return truncated;
}

Just running the SELECT statement will have no effect on the data. You have to use an UPDATE statement with the REPLACE to make the change occur:

UPDATE photos
   SET caption = REPLACE(caption,'"','\'')

Here is a working sample: http://sqlize.com/7FjtEyeLAh

You could google on "tuple unpacking". This can be used in various places in Python. The simplest is in assignment

>>> x = (1,2)
>>> a, b = x
>>> a
1
>>> b
2

In a for loop it works similarly. If each element of the iterable is a tuple, then you can specify two variables and each element in the loop will be unpacked to the two.

>>> x = [(1,2), (3,4), (5,6)]
>>> for item in x:
...     print "A tuple", item
A tuple (1, 2)
A tuple (3, 4)
A tuple (5, 6)
>>> for a, b in x:
...     print "First", a, "then", b
First 1 then 2
First 3 then 4
First 5 then 6

The enumerate function creates an iterable of tuples, so it can be used this way.

You are wasting your time:

1. You are about to write a lot of useless code and introduce new bugs.
2. To execute the function, your user will need to know the P1 name anyway.
3. Etc., etc., etc.

Just put all your functions in the .py file:

# my_module.py

def f1():
    pass

def f2():
    pass

def f3():
    pass

And use them like this:

import my_module

my_module.f1()
my_module.f2()
my_module.f3()

or:

from my_module import f1
from my_module import f2
from my_module import f3

f1()
f2()
f3()

This should be enough for starters.

When you have own struct, you could have own convert-to-string function.

package main

import (
    "fmt"
)

type Color struct {
    Red   int `json:"red"`
    Green int `json:"green"`
    Blue  int `json:"blue"`
}

func (c Color) String() string {
    return fmt.Sprintf("[%d, %d, %d]", c.Red, c.Green, c.Blue)
}

func main() {
    c := Color{Red: 123, Green: 11, Blue: 34}
    fmt.Println(c) //[123, 11, 34]
}

Use this function Number(x).toFixed(2);

To run or convert batch files externally from PowerShell (particularly if you wish to sign all your scheduled task scripts with a certificate) I simply create a PowerShell script, e.g. deletefolders.ps1.

Input the following into the script:

cmd.exe /c "rd /s /q C:\#TEMP\test1"

cmd.exe /c "rd /s /q C:\#TEMP\test2"

cmd.exe /c "rd /s /q C:\#TEMP\test3"

*Each command needs to be put on a new line calling cmd.exe again.

This script can now be signed and run from PowerShell outputting the commands to command prompt / cmd directly.

It is a much safer way than running batch files!

I came by the same error on an old 2010 Exchange Server. A service(Exchange mailbox replication service) was giving out the above error and the migration process could not be continued. Searching through the internet, i came by this link which stated the below:

The Exchange GRE fails to open when installed for the first time or if any changes are made to the IIS server. It fails with snap-in error and when you try to open the snap-in page, the following content is displayed:

This collection already contains an address with scheme http.  There can be at most one address per scheme in this collection. If your service is being hosted in IIS you can fix the problem by setting 'system.serviceModel/serviceHostingEnvironment/multipleSiteBindingsEnabled' to true or specifying 'system.serviceModel/serviceHostingEnvironment/baseAddressPrefixFilters'."

Cause: This error occurs because http port number 443 is already in use by another application and the IIS server is not configured to handle multiple binding to the same port.

Solution: Configure IIS server to handle multiple port bindings. Contact the vendor (Microsoft) to configure it.

Since these services were offered from an IIS Web Server, checking the Bindings on the Root Site fixed the problem. Someone had messed up the Site Bindings, defining rules that were overlapping themselves and messed up the services.

Fixing the correct Bindings resolved the problem, in my case, and i did not have to configure the Web.Config.

There are 2 Reasons why we have to Normalize Input Features before Feeding them to Neural Network:

Reason 1: If a Feature in the Dataset is big in scale compared to others then this big scaled feature becomes dominating and as a result of that, Predictions of the Neural Network will not be Accurate.

Example: In case of Employee Data, if we consider Age and Salary, Age will be a Two Digit Number while Salary can be 7 or 8 Digit (1 Million, etc..). In that Case, Salary will Dominate the Prediction of the Neural Network. But if we Normalize those Features, Values of both the Features will lie in the Range from (0 to 1).

Reason 2: Front Propagation of Neural Networks involves the Dot Product of Weights with Input Features. So, if the Values are very high (for Image and Non-Image Data), Calculation of Output takes a lot of Computation Time as well as Memory. Same is the case during Back Propagation. Consequently, Model Converges slowly, if the Inputs are not Normalized.

Example: If we perform Image Classification, Size of Image will be very huge, as the Value of each Pixel ranges from 0 to 255. Normalization in this case is very important.

Mentioned below are the instances where Normalization is very important:

1. K-Means
2. K-Nearest-Neighbours
3. Principal Component Analysis (PCA)
4. Gradient Descent

You can also run conditional statements on the Postion() which can be really helpful in many scenarios.

for eg.

 <xsl:if test="(position( )) = 1">
     //Show header only once
    </xsl:if>

Be sure you only have one version of NodeJS installed. Try these two:

node --version
sudo node --version

I initially installed NodeJS from source, but it was the incorrect version and 'upgraded' to the newest version using nvm, which doesn't remove any previous versions, and only installs the desired version in the /root/.nvm/versions/... directory. So sudo node was still pointing to the previous version, whilst node was pointing to the newer version.

Instead of passing variable to template globally, you can define a base template and render the 'global part' in it. The base template can be inherited.

Example of rendering template From the symfony Documentation:

<div id="sidebar">
  {% render "AcmeArticleBundle:Article:recentArticles" with {'max': 3} %}
</div>

I had a requirement to provide a report showing details by month where the date field was formatted as date & time, I simply changed the formatting of the date column to "General" and then used the following formula in a new column,

=CONCATENATE(YEAR(C2),MONTH(C2)) 

I'm on Gson 2.8.6 and discovered this bug today.

My approach allows all our existing clients (mobile/web/etc) to continue functioning as they were, but adds some handling for those using 24h formats and allows millis too, for good measure.

Gson rawGson = new Gson();
SimpleDateFormat fmt = new SimpleDateFormat("MMM d, yyyy HH:mm:ss")
private class DateDeserializer implements JsonDeserializer<Date> {
    @Override
    public Date deserialize(JsonElement json, Type typeOfT, JsonDeserializationContext context)
            throws JsonParseException {
        try {
            return new rawGson.fromJson(json, Date.class);
        } catch (JsonSyntaxException e) {}
        String timeString = json.getAsString();
        log.warning("Standard date deserialization didn't work:" + timeString);
        try {
            return fmt.parse(timeString);
        } catch (ParseException e) {}
        log.warning("Parsing as json 24 didn't work:" + timeString);
        return new Date(json.getAsLong());
    }
}

Gson gson = new GsonBuilder()
    .registerTypeAdapter(Date.class, new DateDeserializer())
    .create();

I kept serialization the same as all clients understand the standard json date format.

Ordinarily, I don't think it's good practice to use try/catch blocks, but this should be a fairly rare case.

Python has control flow statements instead of goto statements. One implementation of control flow is Python's while loop. You can give it a boolean condition (boolean values are either True or False in Python), and the loop will execute repeatedly until that condition becomes false. If you want to loop forever, all you have to do is start an infinite loop.

Be careful if you decide to run the following example code. Press Control+C in your shell while it is running if you ever want to kill the process. Note that the process must be in the foreground for this to work.

while True:
    # do stuff here
    pass

The line # do stuff here is just a comment. It doesn't execute anything. pass is just a placeholder in python that basically says "Hi, I'm a line of code, but skip me because I don't do anything."

Now let's say you want to repeatedly ask the user for input forever and ever, and only exit the program if the user inputs the character 'q' for quit.

You could do something like this:

while True:
    cmd = raw_input('Do you want to quit? Enter \'q\'!')
    if cmd == 'q':
        break

cmd will just store whatever the user inputs (the user will be prompted to type something and hit enter). If cmd stores just the letter 'q', the code will forcefully break out of its enclosing loop. The break statement lets you escape any kind of loop. Even an infinite one! It is extremely useful to learn if you ever want to program user applications which often run on infinite loops. If the user does not type exactly the letter 'q', the user will just be prompted repeatedly and infinitely until the process is forcefully killed or the user decides that he's had enough of this annoying program and just wants to quit.

If you actually have set a root password and you've just lost/forgotten it:

1. Stop MySQL

2. Restart it manually with the skip-grant-tables option: mysqld_safe --skip-grant-tables

3. Now, open a new terminal window and run the MySQL client: mysql -u root

4. Reset the root password manually with this MySQL command: UPDATE mysql.user SET Password=PASSWORD('password') WHERE User='root'; If you are using MySQL 5.7 (check using mysql --version in the Terminal) then the command is:

   UPDATE mysql.user SET authentication_string=PASSWORD('password')  WHERE  User='root';
   

5. Flush the privileges with this MySQL command: FLUSH PRIVILEGES;

(Maybe this isn't what you need, Abs, but I figure it could be useful for people stumbling across this question in the future)

Try this. Just pass in the param you want to remove from the URL and the original URL value, and the function will strip it out for you.

function removeParam(key, sourceURL) {
    var rtn = sourceURL.split("?")[0],
        param,
        params_arr = [],
        queryString = (sourceURL.indexOf("?") !== -1) ? sourceURL.split("?")[1] : "";
    if (queryString !== "") {
        params_arr = queryString.split("&");
        for (var i = params_arr.length - 1; i >= 0; i -= 1) {
            param = params_arr[i].split("=")[0];
            if (param === key) {
                params_arr.splice(i, 1);
            }
        }
        if (params_arr.length) rtn = rtn + "?" + params_arr.join("&");
    }
    return rtn;
}

To use it, simply do something like this:

var originalURL = "http://yourewebsite.com?id=10&color_id=1";
var alteredURL = removeParam("color_id", originalURL);

The var alteredURL will be the output you desire.

Hope it helps!
