That's because these things (I mean tooltip etc) are jQuery plug-ins. And yes, they assume some basic knowledge about jQuery. I would suggest you to look for at least a basic tutorial about jQuery.

You'll always have to define which elements should have a tooltip. And I don't understand why Bootstrap should provide the class, you define those classes or yourself. Maybe you were hoping that bootstrap did automatically some magic? This magic however, can cause a lot of problems as well (unwanted side effects).

This magic can be easily achieved to just write $(".myclass").tooltip(), this line of code does exact what you want. The only thing you have to do is attach the myclass class to those elements that need to apply the tooltip thingy. (Just make sure you run that line of code after your DOM has been loaded. See below.)

$(document).ready(function() {
    $(".myclass").tooltip();
});

EDIT: apparently you can't use the class tooltip (probably because it is somewhere internally used!).

I'm just wondering why bootstrap doesn't run the code you specified with some class I can include.

The thing you want produces almost the same code as you have to do now. The biggest reason however they did not do that, is because it causes a lot of trouble. One person wants to assign it to an element with an ID; others want to assign it to elements with a specified classname; and again others want to assign it to one specified element achieved through some selection process. Those 3 options cause extra complexity, while it is already provided by jQuery. I haven't seen many plugins do what you want (just because it is needless; it really doesn't save you code).

In standard C++, technically there is no way to do this since standard C++ has no conception of directories. If you want to expand your net a little bit, you might like to look at using Boost.FileSystem. This has been accepted for inclusion in TR2, so this gives you the best chance of keeping your implementation as close as possible to the standard.

An example, taken straight from the website:

bool find_file( const path & dir_path,         // in this directory,
                const std::string & file_name, // search for this name,
                path & path_found )            // placing path here if found
{
  if ( !exists( dir_path ) ) return false;
  directory_iterator end_itr; // default construction yields past-the-end
  for ( directory_iterator itr( dir_path );
        itr != end_itr;
        ++itr )
  {
    if ( is_directory(itr->status()) )
    {
      if ( find_file( itr->path(), file_name, path_found ) ) return true;
    }
    else if ( itr->leaf() == file_name ) // see below
    {
      path_found = itr->path();
      return true;
    }
  }
  return false;
}

another way to create a data url from blob url may be using canvas.

var canvas = document.createElement("canvas")
var context = canvas.getContext("2d")
context.drawImage(img, 0, 0) // i assume that img.src is your blob url
var dataurl = canvas.toDataURL("your prefer type", your prefer quality)

as what i saw in mdn, canvas.toDataURL is supported well by browsers. (except ie<9, always ie<9)

Hello here we have a better way to apply fonts on EditTexts and TextViews on android at once and apply it in whole project.

First of All you need to make fonts folder. Here are Steps.

1: Go to the (project folder) Then app>src>main

2: Create folders named 'assets/fonts' into the main folder.

3: Put your fonts into the fonts folder. Here I Have 'MavenPro-Regular.ttf'

Here are the Steps for applying custom fonts on EditText and using this approach you can apply fonts on every input.

1 : Create a Class MyEditText (your preferred name ...)

2 : which extends EditText

3 : Apply your font

Here is code Example;

public class MyEditText extends EditText {

    public MyEditText(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        init();
    }

    public MyEditText(Context context, AttributeSet attrs) {
        super(context, attrs);
        init();
    }

    public MyEditText(Context context) {
        super(context);
        init();
    }

    private void init() {
        if (!isInEditMode()) {
            Typeface tf = Typeface.createFromAsset(getContext().getAssets(), "fonts/MavenPro-Regular.ttf");
            setTypeface(tf);
        }
    }

}

And in Here is the code how to use it.

MyEditText editText = (MyEditText) findViewById(R.id.editText);

editText.setText("Hello");

Or in Your xml File

   <MyEditText
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center"
    android:textColor="#fff"
    android:textSize="16dp"
    android:id="@+id/editText"
    />

'So from this discussion i am thinking this should be the code then.

Sub Button1_Click()
    Dim excel As excel.Application
    Dim wb As excel.Workbook
    Dim sht As excel.Worksheet
    Dim f As Object

    Set f = Application.FileDialog(3)
    f.AllowMultiSelect = False
    f.Show

    Set excel = CreateObject("excel.Application")
    Set wb = excel.Workbooks.Open(f.SelectedItems(1))
    Set sht = wb.Worksheets("Data")

    sht.Activate
    sht.Columns("A:G").Copy
    Range("A1").PasteSpecial Paste:=xlPasteValues


    wb.Close
End Sub

'Let me know if this is correct or a step was missed. Thx.

Note that ord() doesn't give you the ASCII value per se; it gives you the numeric value of the character in whatever encoding it's in. Therefore the result of ord('ä') can be 228 if you're using Latin-1, or it can raise a TypeError if you're using UTF-8. It can even return the Unicode codepoint instead if you pass it a unicode:

>>> ord(u'?')
12354

setTimeout would not hold and resume on your own thread however Thread.sleep does. There is no actual equal in Javascript

You can achieve this by adding alternating style classes to each list item

<ul>
    <li class="odd"><a href="link">Link 1</a></li>
    <li><a href="link">Link 2</a></li>
    <li class="odd"><a href="link">Link 2</a></li>
    <li><a href="link">Link 2</a></li>
</ul>

And then styling it like

li { backgorund:white; }
li.odd { background:silver; }

You can further automate this process with javascript (jQuery example below)

$(document).ready(function() {
  $('table tbody tr:odd').addClass('odd');
});

I don't suppose performance matters much here, but I can't resist. The zip() function completely recopies both vectors (more of a matrix transpose, actually) just to get the data in "Pythonic" order. It would be interesting to time the nuts-and-bolts implementation:

import math
def cosine_similarity(v1,v2):
    "compute cosine similarity of v1 to v2: (v1 dot v2)/{||v1||*||v2||)"
    sumxx, sumxy, sumyy = 0, 0, 0
    for i in range(len(v1)):
        x = v1[i]; y = v2[i]
        sumxx += x*x
        sumyy += y*y
        sumxy += x*y
    return sumxy/math.sqrt(sumxx*sumyy)

v1,v2 = [3, 45, 7, 2], [2, 54, 13, 15]
print(v1, v2, cosine_similarity(v1,v2))

Output: [3, 45, 7, 2] [2, 54, 13, 15] 0.972284251712

That goes through the C-like noise of extracting elements one-at-a-time, but does no bulk array copying and gets everything important done in a single for loop, and uses a single square root.

ETA: Updated print call to be a function. (The original was Python 2.7, not 3.3. The current runs under Python 2.7 with a from __future__ import print_function statement.) The output is the same, either way.

CPYthon 2.7.3 on 3.0GHz Core 2 Duo:

>>> timeit.timeit("cosine_similarity(v1,v2)",setup="from __main__ import cosine_similarity, v1, v2")
2.4261788514654654
>>> timeit.timeit("cosine_measure(v1,v2)",setup="from __main__ import cosine_measure, v1, v2")
8.794677709375264

So, the unpythonic way is about 3.6 times faster in this case.

Basically, ajax request as well as synchronous request sends your document cookies automatically. So, you need to set your cookie to document, not to request. However, your request is cross-domain, and things became more complicated. Basing on this answer, additionally to set document cookie, you should allow its sending to cross-domain environment:

type: "GET",    
url: "http://example.com",
cache: false,
// NO setCookies option available, set cookie to document
//setCookies: "lkfh89asdhjahska7al446dfg5kgfbfgdhfdbfgcvbcbc dfskljvdfhpl",
crossDomain: true,
dataType: 'json',
xhrFields: {
    withCredentials: true
},
success: function (data) {
    alert(data);
});

Or, the file is of a filetype and/or architecture that you just cannot run with your hardware and/or there is also no fallback binfmt_misc entry to handle the particular format in some other way. Use file(1) to determine.

I was also struggling with a similar issue dealing with exporting data into an Excel spreadsheet using C#. I tried many different methods working with external DLLs and had no luck.

For the export functionality you do not need to use anything dealing with the external DLLs. Instead, just maintain the header and content type of the response.

Here is an article that I found rather helpful. The article talks about how to export data to Excel spreadsheets using ASP.NET.

http://www.icodefor.net/2016/07/export-data-to-excel-sheet-in-asp-dot-net-c-sharp.html

Changing your lists to numpy arrays will do the job!!

import matplotlib.pyplot as plt
from scipy import stats
import numpy as np 

x = np.array([0.46,0.59,0.68,0.99,0.39,0.31,1.09,0.77,0.72,0.49,0.55,0.62,0.58,0.88,0.78]) # x is a numpy array now
y = np.array([0.315,0.383,0.452,0.650,0.279,0.215,0.727,0.512,0.478,0.335,0.365,0.424,0.390,0.585,0.511]) # y is a numpy array now
xerr = [0.01]*15
yerr = [0.001]*15

plt.rc('font', family='serif', size=13)
m, b = np.polyfit(x, y, 1)
plt.plot(x,y,'s',color='#0066FF')
plt.plot(x, m*x + b, 'r-') #BREAKS ON THIS LINE
plt.errorbar(x,y,xerr=xerr,yerr=0,linestyle="None",color='black')
plt.xlabel('$\Delta t$ $(s)$',fontsize=20)
plt.ylabel('$\Delta p$ $(hPa)$',fontsize=20)
plt.autoscale(enable=True, axis=u'both', tight=False)
plt.grid(False)
plt.xlim(0.2,1.2)
plt.ylim(0,0.8)
plt.show()

  for(var i = 0; i < BoardMessages.length;i++){
        (function(j){
            console.log("Loading message %d".green, j);
            htmlMessageboardString += MessageToHTMLString(BoardMessages[j]);
        })(i);
  }

That should work; however, you should never create a function in a loop. Therefore,

  for(var i = 0; i < BoardMessages.length;i++){
        composeMessage(BoardMessages[i]);
  }

  function composeMessage(message){
      console.log("Loading message %d".green, message);
      htmlMessageboardString += MessageToHTMLString(message);
  }

Visual Studio will automatically create them. I don't recommend putting them in source control. There have been numerous times where a local developer's SOU file was causing VS to behave erratically on that developers box. Deleting the file and then letting VS recreate it always fixed the issues.

another option is to use an iframe and set the form's target to it.

you may try this (it uses jQuery):

function ajax_form($form, on_complete)
{
    var iframe;

    if (!$form.attr('target'))
    {
        //create a unique iframe for the form
        iframe = $("<iframe></iframe>").attr('name', 'ajax_form_' + Math.floor(Math.random() * 999999)).hide().appendTo($('body'));
        $form.attr('target', iframe.attr('name'));
    }

    if (on_complete)
    {
        iframe = iframe || $('iframe[name="' + $form.attr('target') + '"]');
        iframe.load(function ()
        {
            //get the server response
            var response = iframe.contents().find('body').text();
            on_complete(response);
        });
    }
}

it works well with all browsers, you don't need to serialize or prepare the data. one down side is that you can't monitor the progress.

also, at least for chrome, the request will not appear in the "xhr" tab of the developer tools but under "doc"

in swift 4 to convert to url use URL

let fileUrl = URL.init(fileURLWithPath: filePath)

or

let fileUrl = URL(fileURLWithPath: filePath)

Another good use for *args and **kwargs: you can define generic "catch all" functions, which is great for decorators where you return such a wrapper instead of the original function.

An example with a trivial caching decorator:

import pickle, functools
def cache(f):
  _cache = {}
  def wrapper(*args, **kwargs):
    key = pickle.dumps((args, kwargs))
    if key not in _cache:
      _cache[key] = f(*args, **kwargs) # call the wrapped function, save in cache
    return _cache[key] # read value from cache
  functools.update_wrapper(wrapper, f) # update wrapper's metadata
  return wrapper

import time
@cache
def foo(n):
  time.sleep(2)
  return n*2

foo(10) # first call with parameter 10, sleeps
foo(10) # returns immediately

In case anyone face pip issue like below

pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.

The root cause is openssl 1.1 doesn’t support python 3.6 anymore. So you need to install old version openssl 1.0

here is the solution:

brew uninstall --ignore-dependencies openssl
brew install https://github.com/tebelorg/Tump/releases/download/v1.0.0/openssl.rb

I used:

Get-Content c:\FileToAppend_*.log | Out-File -FilePath C:\DestinationFile.log 
-Encoding ASCII -Append

This appended fine. I added the ASCII encoding to remove the nul characters Notepad++ was showing without the explicit encoding.

<form  id="myform_id" action="/myMethode"  role="form"  method="post" > 
   <a  href="javascript:$('#myform_id').submit();" >submit</a>
</form>

I don't often develop in asp.net, however when it comes to loggers I think a lot of best practices are universal. Here are some of my random thoughts on logging that I have learned over the years:

Frameworks

• Use a logger abstraction framework - like slf4j (or roll your own), so that you decouple the logger implementation from your API. I have seen a number of logger frameworks come and go and you are better off being able to adopt a new one without much hassle.
• Try to find a framework that supports a variety of output formats.
• Try to find a framework that supports plugins / custom filters.
• Use a framework that can be configured by external files, so that your customers / consumers can tweak the log output easily so that it can be read by commerical log management applications with ease.
• Be sure not to go overboard on custom logging levels, otherwise you may not be able to move to different logging frameworks.

Logger Output

• Try to avoid XML/RSS style logs for logging that could encounter catastrophic failures. This is important because if the power switch is shut off without your logger writing the closing </xxx> tag, your log is broken.
• Log threads. Otherwise, it can be very difficult to track the flow of your program.
• If you have to internationalize your logs, you may want to have a developer only log in English (or your language of choice).
• Sometimes having the option to insert logging statements into SQL queries can be a lifesaver in debugging situations. Such as:

    -- Invoking Class: com.foocorp.foopackage.FooClass:9021
    SELECT * FROM foo;

• You want class-level logging. You normally don't want static instances of loggers as well - it is not worth the micro-optimization.
• Marking and categorizing logged exceptions is sometimes useful because not all exceptions are created equal. So knowing a subset of important exceptions a head of time is helpful, if you have a log monitor that needs to send notifications upon critical states.
• Duplication filters will save your eyesight and hard disk. Do you really want to see the same logging statement repeated 10^10000000 times? Wouldn't it be better just to get a message like: This is my logging statement - Repeated 100 times

Also see this question of mine.

Try:

System.getProperty("os.name");

From the bottom of the ?mutate_each (at least in dplyr 0.5) it looks like that function, as in @docendo discimus's answer, will be deprecated and replaced with more flexible alternatives mutate_if, mutate_all, and mutate_at. The one most similar to what @hadley mentions in his comment is probably using mutate_at. Note the order of the arguments is reversed, compared to mutate_each, and vars() uses select() like semantics, which I interpret to mean the ?select_helpers functions.

dat %>% mutate_at(vars(starts_with("fac")),funs(factor)) %>%   
  mutate_at(vars(starts_with("dbl")),funs(as.numeric))

But mutate_at can take column numbers instead of a vars() argument, and after reading through this page, and looking at the alternatives, I ended up using mutate_at but with grep to capture many different kinds of column names at once (unless you always have such obvious column names!)

dat %>% mutate_at(grep("^(fac|fctr|fckr)",colnames(.)),funs(factor)) %>%
  mutate_at(grep("^(dbl|num|qty)",colnames(.)),funs(as.numeric))

I was pretty excited about figuring out mutate_at + grep, because now one line can work on lots of columns.

EDIT - now I see matches() in among the select_helpers, which handles regex, so now I like this.

dat %>% mutate_at(vars(matches("fac|fctr|fckr")),funs(factor)) %>%
  mutate_at(vars(matches("dbl|num|qty")),funs(as.numeric))

Another generally-related comment - if you have all your date columns with matchable names, and consistent formats, this is powerful. In my case, this turns all my YYYYMMDD columns, which were read as numbers, into dates.

  mutate_at(vars(matches("_DT$")),funs(as.Date(as.character(.),format="%Y%m%d")))

You can use UIGraphicsBeginImageContext method to set the size of image same that of view.

Syntax : void UIGraphicsBeginImageContext(CGSize size);

 #define IMAGE(imageName) (UIImage *)[UIImage imageWithContentsOfFile:
  [[NSBundle mainBundle] pathForResource:imageName ofType:IMAGE_TYPE_PNG]]

        UIGraphicsBeginImageContext(self.view.frame.size);
        [[UIImage imageNamed:@“MyImage.png"] drawInRect:self.view.bounds];
        UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
        UIGraphicsEndImageContext();

    self.view.backgroundColor = [UIColor colorWithPatternImage:IMAGE(@"mainBg")];

Two things. First, you must base64 decode the mykey.pem file yourself. Second, the openssl private key format is specified in PKCS#1 as the RSAPrivateKey ASN.1 structure. It is not compatible with java's PKCS8EncodedKeySpec, which is based on the SubjectPublicKeyInfo ASN.1 structure. If you are willing to use the bouncycastle library you can use a few classes in the bouncycastle provider and bouncycastle PKIX libraries to make quick work of this.

import java.io.BufferedReader;
import java.io.FileReader;
import java.security.KeyPair;
import java.security.Security;

import org.bouncycastle.jce.provider.BouncyCastleProvider;
import org.bouncycastle.openssl.PEMKeyPair;
import org.bouncycastle.openssl.PEMParser;
import org.bouncycastle.openssl.jcajce.JcaPEMKeyConverter;

// ...   

String keyPath = "mykey.pem";
BufferedReader br = new BufferedReader(new FileReader(keyPath));
Security.addProvider(new BouncyCastleProvider());
PEMParser pp = new PEMParser(br);
PEMKeyPair pemKeyPair = (PEMKeyPair) pp.readObject();
KeyPair kp = new JcaPEMKeyConverter().getKeyPair(pemKeyPair);
pp.close();
samlResponse.sign(Signature.getInstance("SHA1withRSA").toString(), kp.getPrivate(), certs);

the best one :D (RFC-friendly & no error "too complex") :

function    isMail(mail)
{
    pattuser = /^([A-Z0-9_%+\-!#$&'*\/=?^`{|}~]+\.?)*[A-Z0-9_%+\-!#$&'*\/=?^`{|}~]+$/i;
    pattdomain = /^([A-Z0-9-]+\.?)*[A-Z0-9-]+(\.[A-Z]{2,9})+$/i;

    tab = mail.split("@");
    if (tab.length != 2)
        return false;
    return (pattuser.test(tab[0]) && pattdomain.test(tab[1]));
}

A similar looking answer was downvoted. But I think I can justify what I'm suggesting here for limited cases.

While it's true that an observable doesn't have a current value, very often it will have an immediately available value. For example with redux / flux / akita stores you may request data from a central store, based on a number of observables and that value will generally be immediately available.

If this is the case then when you subscribe, the value will come back immediately.

So let's say you had a call to a service, and on completion you want to get the latest value of something from your store, that potentially might not emit:

You might try to do this (and you should as much as possible keep things 'inside pipes'):

 serviceCallResponse$.pipe(withLatestFrom(store$.select(x => x.customer)))
                     .subscribe(([ serviceCallResponse, customer] => {

                        // we have serviceCallResponse and customer 
                     });

The problem with this is that it will block until the secondary observable emits a value, which potentially could be never.

I found myself recently needing to evaluate an observable only if a value was immediately available, and more importantly I needed to be able to detect if it wasn't. I ended up doing this:

 serviceCallResponse$.pipe()
                     .subscribe(serviceCallResponse => {

                        // immediately try to subscribe to get the 'available' value
                        // note: immediately unsubscribe afterward to 'cancel' if needed
                        let customer = undefined;

                        // whatever the secondary observable is
                        const secondary$ = store$.select(x => x.customer);

                        // subscribe to it, and assign to closure scope
                        sub = secondary$.pipe(take(1)).subscribe(_customer => customer = _customer);
                        sub.unsubscribe();

                        // if there's a delay or customer isn't available the value won't have been set before we get here
                        if (customer === undefined) 
                        {
                           // handle, or ignore as needed
                           return throwError('Customer was not immediately available');
                        }
                     });

Note that for all of the above I'm using subscribe to get the value (as @Ben discusses). Not using a .value property, even if I had a BehaviorSubject.

from TypeScript you can use native JS array filter() method:

let filteredElements=array.filter(element => element.field == filterValue);

it returns an array with only matching elements from the original array (0, 1 or more)

Reference: https://developer.mozilla.org/it/docs/Web/JavaScript/Reference/Global_Objects/Array/filter

for Z score, we can stick to documentation instead of using 'apply' function

from scipy.stats import zscore
df_zscore = zscore(cols as array, axis=1)

This can also be achieved using the Scalar-Valued Function in MSSQL 2008
Declare your function as following,

CREATE FUNCTION [dbo].[FunctionName]
(@MaskId INT)
RETURNS Varchar(500) 
AS
BEGIN

    DECLARE @SchoolName varchar(500)                        

    SELECT @SchoolName =ISNULL(@SchoolName ,'')+ MD.maskdetail +', ' 
    FROM maskdetails MD WITH (NOLOCK)       
    AND MD.MaskId=@MaskId

    RETURN @SchoolName

END

And then your final query will be like

SELECT m.maskid,m.maskname,m.schoolid,s.schoolname,
(SELECT [dbo].[FunctionName](m.maskid)) 'maskdetail'
FROM tblmask m JOIN school s on s.id = m.schoolid 
ORDER BY m.maskname ;

Note: You may have to change the function, as I don't know the complete table structure.

When using <abc [(bar)]="foo"/> syntax on angular.

This translates to: <abc [bar]="foo" (barChange)="foo = $event" />

Which means your component should have:

@Input() bar;
@Output() barChange = new EventEmitter();

This kind of code perhaps should work for You

SELECT
 *,
 CASE
  WHEN (pvc IS NULL OR pvc = '') AND (datepose < 1980) THEN '01'
  WHEN (pvc IS NULL OR pvc = '') AND (datepose >= 1980) THEN '02'
  WHEN (pvc IS NULL OR pvc = '') AND (datepose IS NULL OR datepose = 0) THEN '03'
  ELSE '00'
 END AS modifiedpvc
FROM my_table;


 gid | datepose | pvc | modifiedpvc 
-----+----------+-----+-------------
   1 |     1961 | 01  | 00
   2 |     1949 |     | 01
   3 |     1990 | 02  | 00
   1 |     1981 |     | 02
   1 |          | 03  | 00
   1 |          |     | 03

I know its an old question. This problem can be easily reproduced if you try to reinitialize the Datatable again.

For example in your function somewhere you are calling $('#example').DataTable( { searching: false} ); again.

There is easy resolving this issue. Please follow the steps

1. Initialize the Datatable to a variable rather than directly initializing DataTable method.
   1. For Example Instead of calling $('#example').DataTable( { searching: false} ); try to declare it globally (or in scope of javascription that you are using) like this var table = $('#example').DataTable( { searching: false } );.
2. Now Whenever you are calling this method $('#example').DataTable( { searching: false} ); again then before calling it perform the following actions
   3. if (table != undefined && table != null) { table.destroy(); table = null; }
3. Once you have followed the steps above then go ahead with re-initializing the table with same variable without using var keyword (as you have already defined it) i.e table = $('#example').DataTable( { searching: false } );

"What does if __name__==“__main__”: do?" has already been answered.

Having a main() function allows you to call its functionality if you import the module. The main (no pun intended) benefit of this (IMHO) is that you can unit test it.

You are trying to return an object. Because there is no good way to represent an object as a string, the object's .toString() value is automatically set as "[object Object]".

Using OnPaint to draw a custom border on your controls is fine. But know how to use OnPaint to keep efficiency up, and render time to a minimum. Read this if you are experiencing a laggy GUI while using custom paint routines: What is the right way to use OnPaint in .Net applications?

Because the accepted answer of PraVn may seem simple, but is actually inefficient. Using a custom control, like the ones posted in the answers above is way better.

Maybe the performance is not an issue in your application, because it is small, but for larger applications with a lot of custom OnPaint routines it is a wrong approach to use the way PraVn showed.

application/xml is seen by svn as binary type whereas text/xml as text file for which a diff can be displayed.

This worked perfectly fine for me. Add the annotation @JsonIgnore on the child class where you mention the reference to the parent class.

@ManyToOne
@JoinColumn(name = "ID", nullable = false, updatable = false)
@JsonIgnore
private Member member;

I would use a single Context class inheriting from IdentityDbContext. This way you can have the context be aware of any relations between your classes and the IdentityUser and Roles of the IdentityDbContext. There is very little overhead in the IdentityDbContext, it is basically a regular DbContext with two DbSets. One for the users and one for the roles.

var dateDisplay = new Date( 2016-11-09 05:27:00 UTC );
dateDisplay = dateDisplay.toString()
var arr = (dateDisplay.split(' '))
var date_String =  arr[0]+','+arr[1]+' '+arr[2]+' '+arr[3]+','+arr[4]

this will show string like Wed,Nov 09 2016,10:57:00

The short answer is: most of the time time.clock() will be better. However, if you're timing some hardware (for example some algorithm you put in the GPU), then time.clock() will get rid of this time and time.time() is the only solution left.

Note: whatever the method used, the timing will depend on factors you cannot control (when will the process switch, how often, ...), this is worse with time.time() but exists also with time.clock(), so you should never run one timing test only, but always run a series of test and look at mean/variance of the times.

 Fragment fr = new Fragment_class();
             FragmentManager fm = getFragmentManager();
            FragmentTransaction fragmentTransaction = fm.beginTransaction();
            fragmentTransaction.add(R.id.viewpagerId, fr);
            fragmentTransaction.commit();

Just to be precise, R.id.viewpagerId is cretaed in your current class layout, upon calling, the new fragment automatically gets infiltrated.

REVOKE CONNECT will not prevent the connections from the db owner or superuser. So if you don't want anyone to connect the db, follow command may be useful.

alter database pilot allow_connections = off;

Then use:

SELECT pg_terminate_backend(pid)
FROM pg_stat_activity
WHERE datname = 'pilot';

Well, you're going to have to check for null somewhere. You could do something like this:

from item in db.vw_Dropship_OrderItems
         where (listStatus == null || listStatus.Contains(item.StatusCode)) 
            && (listMerchants == null || listMerchants.Contains(item.MerchantId))
         select item;

Div of style, position:absolute;bottom:5px;width:100%; is working, But it required more scrollup situation.

window.onscroll = function() {
    var v = document.getElementById("copyright");
    v.style.position = "fixed";
    v.style.bottom = "5px";
}

The yum install php-soap command will install the Soap module for php 5.x

For installing the correct version for your environment I recommend to create a file info.php and put this code: <?php echo phpinfo(); ?>

In the header you'll see the version you're using:

Now that you know the correct version you can run this command: yum search php-soap

This command will return the avaliable versions:

php-soap.x86_64 : A module for PHP applications that use the SOAP protocol
php54-php-soap.x86_64 : A module for PHP applications that use the SOAP protocol
php55-php-soap.x86_64 : A module for PHP applications that use the SOAP protocol
php56-php-soap.x86_64 : A module for PHP applications that use the SOAP protocol
php70-php-soap.x86_64 : A module for PHP applications that use the SOAP protocol
php71-php-soap.x86_64 : A module for PHP applications that use the SOAP protocol
php72-php-soap.x86_64 : A module for PHP applications that use the SOAP protocol
php73-php-soap.x86_64 : A module for PHP applications that use the SOAP protocol
php74-php-soap.x86_64 : A module for PHP applications that use the SOAP protocol
rh-php70-php-soap.x86_64 : A module for PHP applications that use the SOAP protocol
rh-php71-php-soap.x86_64 : A module for PHP applications that use the SOAP protocol
rh-php72-php-soap.x86_64 : A module for PHP applications that use the SOAP protocol

Now you just need to choose the correct module to your php version.

For this example, you should run this command php72-php-soap.x86_64

Fur future readers, if you are using Angular 1.6, you also need to change the hashPrefix:

appModule.config(['$locationProvider', function($locationProvider) {
    $locationProvider.html5Mode(true);
    $locationProvider.hashPrefix('');
}]);

Don't forget to set the base in your HTML <head>:

<head>
    <base href="/">
    ...
</head>

You need to get hold of the axes themselves. Probably the cleanest way is to change your last row:

lm = sns.lmplot('X','Y',df,col='Z',sharex=False,sharey=False)

Then you can get hold of the axes objects (an array of axes):

axes = lm.axes

After that you can tweak the axes properties

axes[0,0].set_ylim(0,)
axes[0,1].set_ylim(0,)

Operator + is a unary operator which converts value to number. Below I prepared a table with corresponding results of using this operator for different values.

+-----------------------------+-----------+
| Value                       | + (Value) |
+-----------------------------+-----------+
| 1                           | 1         |
| '-1'                        | -1        |
| '3.14'                      | 3.14      |
| '3'                         | 3         |
| '0xAA'                      | 170       |
| true                        | 1         |
| false                       | 0         |
| null                        | 0         |
| 'Infinity'                  | Infinity  |
| 'infinity'                  | NaN       |
| '10a'                       | NaN       |
| undefined                   | Nan       |
| ['Apple']                   | Nan       |
| function(val){ return val } | NaN       |
+-----------------------------+-----------+

Operator + returns value for objects which have implemented method valueOf.

let something = {
    valueOf: function () {
        return 25;
    }
};

console.log(+something);

You can try wrapping the option elements inside a span so that they wont be visible but still be loaded in the DOM. Like below

jQ('#ddlDropdown option').wrap('<span>');

And unwrap the option which contains the 'selected' attribute as follows to display already selected option.

var selectedOption = jQ('#ddlDropdown').find("[selected]");
jQ(selectedOption).unwrap();

This works across all the browsers.

Supply the path relative to the classloader, not the class you're getting the loader from. For instance:

resourcesloader.class.getClassLoader().getResource("package1/resources/repository/SSL-Key/cert.jks").toString();

The folder is part of the URL you set when you create request: "ftp://www.contoso.com/test.htm". If you use "ftp://www.contoso.com/wibble/test.htm" then the file will be uploaded to a folder named wibble.

You may need to first use a request with Method = WebRequestMethods.Ftp.MakeDirectory to make the wibble folder if it doesn't already exist.

is compares identity. A string will never be identical to a not-string.

== is equality. But a string will never be equal to either True or False.

You want neither.

path = '/bla/bla/bla'

if path:
    print "True"
else:
    print "False"

i was facing the same problem in the wp-admin section of the site. I enqueued the underscore script cdn and it fixed the problem.

function kk_admin_scripts() {
    wp_enqueue_script('underscore', '//cdnjs.cloudflare.com/ajax/libs/lodash.js/0.10.0/lodash.min.js' );
}
add_action( 'admin_enqueue_scripts', 'kk_admin_scripts' );

What I know is one reason when “GC overhead limit exceeded” error is thrown when 2% of the memory is freed after several GC cycles

By this error your JVM is signalling that your application is spending too much time in garbage collection. so the little amount GC was able to clean will be quickly filled again thus forcing GC to restart the cleaning process again.

You should try changing the value of -Xmx and -Xms.

Had the same problem in Eclipse STS. Changing the scope in the pom from "provided" to "compile" fixed the problem and when I changed it back everything was still OK.

Just use the formula

=A8*60*24

You can use

SELECT AUTO_INCREMENT
FROM information_schema.tables
WHERE table_name = 'table_name'
AND table_schema = DATABASE( ) ;

or if you do not wish to use information_schema you can use this

SHOW TABLE STATUS LIKE 'table_name'

If you're using PHP 5.5 or PHP 7 above, you may want to use:

function isTodayWeekend() {
    return in_array(date("l"), ["Saturday", "Sunday"]);
}

and it will return "true" if today is weekend and "false" if not.

I was stuck in a situation seeing error: pathspec 'desired-branch' did not match any file(s) known to git. for all of the suggestions above. I'm on git version 1.8.3.1.

So this worked for me:

git fetch origin desired-branch
git checkout -b desired-branch FETCH_HEAD

The explanation behind is that I've noticed that when fetching the remote branch, it was fetched to FETCH_HEAD:

$ git fetch origin desired-branch
From github.com:MYTEAM/my-repo
    * branch            desired-branch -> FETCH_HEAD

scp -r <directory> <username>@<targethost>:<targetdir>

To the top voted answer. I prefer passing by rvalue reference.

I understand what's the problem about passing by rvalue reference may cause. But let's divide this problem to two sides:

• for caller:

I must write code Base newBase(std::move(<lvalue>)) or Base newBase(<rvalue>).

• for callee:

Library author should guarantee it will actually move the unique_ptr to initialize member if it want own the ownership.

That's all.

If you pass by rvalue reference, it will only invoke one "move" instruction, but if pass by value, it's two.

Yep, if library author is not expert about this, he may not move unique_ptr to initialize member, but it's the problem of author, not you. Whatever it pass by value or rvalue reference, your code is same!

If you are writing a library, now you know you should guarantee it, so just do it, passing by rvalue reference is a better choice than value. Client who use you library will just write same code.

Now, for your question. How do I pass a unique_ptr argument to a constructor or a function?

You know what's the best choice.

http://scottmeyers.blogspot.com/2014/07/should-move-only-types-ever-be-passed.html

Use:

git log --graph --abbrev-commit --decorate  --first-parent <branch_name>

It is only for the target branch (of course --graph, --abbrev-commit --decorate are more polishing).

The key option is --first-parent: "Follow only the first parent commit upon seeing a merge commit" (https://git-scm.com/docs/git-log)

It prevents the commit forks from being displayed.

Use Transformation method:

To Hide:

editText.transformationMethod = PasswordTransformationMethod.getInstance()

To Visible:

editText.transformationMethod = SingleLineTransformationMethod.getInstance()

That's it.

Use Fail module.

1. Use ignore_errors with every task that you need to ignore in case of errors.
2. Set a flag (say, result = false) whenever there is a failure in any task execution
3. At the end of the playbook, check if flag is set, and depending on that, fail the execution

- fail: msg="The execution has failed because of errors."
  when: flag == "failed"

Update:

Use register to store the result of a task like you have shown in your example. Then, use a task like this:

- name: Set flag
  set_fact: flag = failed
  when: "'FAILED' in command_result.stderr"

Try this:

Intent logout_intent = new Intent(DashboardActivity.this, LoginActivity.class);
logout_intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
logout_intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
logout_intent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
startActivity(logout_intent);
finish();

for anyone reading this because the text inside your label is not vertically centered, keep in mind that some font types are not designed equally. for example, if you create a label with zapfino size 16, you will see the text is not perfectly centered vertically.

however, working with helvetica will vertically center your text.

Simple example

function lol(second, third) {
    console.log(this.first, second, third);
}

lol(); // undefined, undefined, undefined
lol('1'); // undefined, "1", undefined
lol('1', '2'); // undefined, "1", "2"

lol.call({first: '1'}); // "1", undefined, undefined
lol.call({first: '1'}, '2'); // "1", "2", undefined
lol.call({first: '1'}, '2', '3'); // "1", "2", "3"

lol.apply({first: '1'}); // "1", undefined, undefined
lol.apply({first: '1'}, ['2', '3']); // "1", "2", "3"

const newLol = lol.bind({first: '1'}); 
newLol(); // "1", undefined, undefined
newLol('2'); // "1", "2", undefined
newLol('2', '3'); // "1", "2", "3"

const newOmg = lol.bind({first: '1'}, '2');
newOmg(); // "1", "2", undefined
newOmg('3'); // "1", "2", "3"

const newWtf = lol.bind({first: '1'}, '2', '3');
newWtf(); // "1", "2", "3"

In Python 3.8+ you can do

import hashlib

with open("your_filename.png", "rb") as f:
    file_hash = hashlib.md5()
    while chunk := f.read(8192):
        file_hash.update(chunk)

print(file_hash.digest())
print(file_hash.hexdigest())  # to get a printable str instead of bytes

On Python 3.7 and below:

with open("your_filename.png", "rb") as f:
    file_hash = hashlib.md5()
    chunk = f.read(8192)
    while chunk:
        file_hash.update(chunk)
        chunk = f.read(8192)

print(file_hash.hexdigest())

This reads the file 8192 (or 2¹³) bytes at a time instead of all at once with f.read() to use less memory.

Consider using hashlib.blake2b instead of md5 (just replace md5 with blake2b in the above snippets). It's cryptographically secure and faster than MD5.

Sounds like you want a mirror of the remote repository:

git clone --mirror url://to/remote.git local.git

That command creates a bare repository. If you don't want a bare repository, things get more complicated.

Excel.Application xl = new Excel.ApplicationClass();

Excel.Workbook wb = xl.Workbooks.Add(Excel.XlWBATemplate.xlWBATWorkshe et);

Excel.Worksheet ws = (Excel.Worksheet)wb.ActiveSheet;

ws.Cells[1,1] = "Testing";

Excel.Range range = ws.get_Range(ws.Cells[1,1],ws.Cells[1,2]);

range.Merge(true);

range.Interior.ColorIndex =36;

xl.Visible =true;

It basically means that the application wants to perform some "naming operations" (e.g. JNDI or LDAP lookups), and it didn't have sufficient information available to be able to create a connection to the directory server. As the docs for the exception state,

This exception is thrown when no initial context implementation can be created. The policy of how an initial context implementation is selected is described in the documentation of the InitialContext class.

And if you dutifully have a look at the javadocs for InitialContext, they describe quite well how the initial context is constructed, and what your options are for supplying the address/credentials/etc.

If you have a go at creating the context and get stuck somewhere else, please post back explaining what you've done so far and where you're running aground.

# sudo apt-get install g++-multilib

Should fix this error on 64-bit machines (Debian/Ubuntu).

apparently, the GET and/or the POST variable(s) do(es) not exist. simply test if "isset". (pseudocode):

if(isset($_GET['action'];)) {$action = $_GET['action'];} else { RECOVER FROM ERROR CODE }

In 2 out of 2 occasions of reports IE8 crashing I got it fixed with removing the background-image from the body element in css. Background-colors are no problem and also putting the same background-image on any other element(for example html) is no problem.

The crash only happened in an actual IE8 in IE8 mode. So you can't test this in IE9 compatibility mode and strangely it can indeed be 'fixed' by forcing IE8 to go into IE7 mode.

1. exec is not an expression: a statement in Python 2.x, and a function in Python 3.x. It compiles and immediately evaluates a statement or set of statement contained in a string. Example:

    exec('print(5)')           # prints 5.
    # exec 'print 5'     if you use Python 2.x, nor the exec neither the print is a function there
    exec('print(5)\nprint(6)')  # prints 5{newline}6.
    exec('if True: print(6)')  # prints 6.
    exec('5')                 # does nothing and returns nothing.
   

2. eval is a built-in function (not a statement), which evaluates an expression and returns the value that expression produces. Example:

    x = eval('5')              # x <- 5
    x = eval('%d + 6' % x)     # x <- 11
    x = eval('abs(%d)' % -100) # x <- 100
    x = eval('x = 5')          # INVALID; assignment is not an expression.
    x = eval('if 1: x = 4')    # INVALID; if is a statement, not an expression.
   

3. compile is a lower level version of exec and eval. It does not execute or evaluate your statements or expressions, but returns a code object that can do it. The modes are as follows:

4. compile(string, '', 'eval') returns the code object that would have been executed had you done eval(string). Note that you cannot use statements in this mode; only a (single) expression is valid.

5. compile(string, '', 'exec') returns the code object that would have been executed had you done exec(string). You can use any number of statements here.

6. compile(string, '', 'single') is like the exec mode but expects exactly one expression/statement, eg compile('a=1 if 1 else 3', 'myf', mode='single')

Member references are usually considered bad. They make life hard compared to member pointers. But it's not particularly unsual, nor is it some special named idiom or thing. It's just aliasing.

Once you have your key stored in a PEM file, you can read it back easily using PemObject and PemReader classes provided by BouncyCastle, as shown in this this tutorial.

Create a PemFile class that encapsulates file handling:

import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.InputStreamReader;

import org.bouncycastle.util.io.pem.PemObject;
import org.bouncycastle.util.io.pem.PemReader;

public class PemFile {

    private PemObject pemObject;

    public PemFile(String filename) throws FileNotFoundException, IOException {
        PemReader pemReader = new PemReader(new InputStreamReader(
                new FileInputStream(filename)));
        try {
            this.pemObject = pemReader.readPemObject();
        } finally {
            pemReader.close();
        }
    }

    public PemObject getPemObject() {
        return pemObject;
    }
}

Then instantiate private and public keys as usual:

import java.io.FileNotFoundException;
import java.io.IOException;
import java.security.KeyFactory;
import java.security.NoSuchAlgorithmException;
import java.security.NoSuchProviderException;
import java.security.PrivateKey;
import java.security.PublicKey;
import java.security.Security;
import java.security.spec.InvalidKeySpecException;
import java.security.spec.PKCS8EncodedKeySpec;
import java.security.spec.X509EncodedKeySpec;

import org.apache.log4j.Logger;
import org.bouncycastle.jce.provider.BouncyCastleProvider;

public class Main {

    protected final static Logger LOGGER = Logger.getLogger(Main.class);

    public final static String RESOURCES_DIR = "src/main/resources/rsa-sample/";

    public static void main(String[] args) throws FileNotFoundException,
            IOException, NoSuchAlgorithmException, NoSuchProviderException {
        Security.addProvider(new BouncyCastleProvider());
        LOGGER.info("BouncyCastle provider added.");

        KeyFactory factory = KeyFactory.getInstance("RSA", "BC");
        try {
            PrivateKey priv = generatePrivateKey(factory, RESOURCES_DIR
                    + "id_rsa");
            LOGGER.info(String.format("Instantiated private key: %s", priv));

            PublicKey pub = generatePublicKey(factory, RESOURCES_DIR
                    + "id_rsa.pub");
            LOGGER.info(String.format("Instantiated public key: %s", pub));
        } catch (InvalidKeySpecException e) {
            e.printStackTrace();
        }
    }

    private static PrivateKey generatePrivateKey(KeyFactory factory,
            String filename) throws InvalidKeySpecException,
            FileNotFoundException, IOException {
        PemFile pemFile = new PemFile(filename);
        byte[] content = pemFile.getPemObject().getContent();
        PKCS8EncodedKeySpec privKeySpec = new PKCS8EncodedKeySpec(content);
        return factory.generatePrivate(privKeySpec);
    }

    private static PublicKey generatePublicKey(KeyFactory factory,
            String filename) throws InvalidKeySpecException,
            FileNotFoundException, IOException {
        PemFile pemFile = new PemFile(filename);
        byte[] content = pemFile.getPemObject().getContent();
        X509EncodedKeySpec pubKeySpec = new X509EncodedKeySpec(content);
        return factory.generatePublic(pubKeySpec);
    }
}

Hope this helps.

nc or 'netcat' also has a scan mode which may be of use.

This works for me:

window.onload = function() {
    // short timeout
    setTimeout(function() {
        $(document.body).scrollTop(0);
    }, 15);
};

Uses a short setTimeout inside the onload to give the browser a chance to do the scroll.

Use array notation like name="checkbox[]" in your input element. This will give you $_POST['checkbox'] as array. In the query you can utilize it as

$sql = "DELETE FROM links WHERE link_id in ";
$sql.= "('".implode("','",array_values($_POST['checkbox']))."')";

Thats one single query to delete them all.

Note: You need to escape the values passed in $_POST['checkbox'] with mysql_real_escape_string or similar to prevent SQL Injection.

Android doesn't have special code for sending and receiving HTTP, you can use standard Java code. I'd recommend using the Apache HTTP client, which comes with Android. Here's a snippet of code I used to send an HTTP POST.

I don't understand what sending the object in a variable named "jason" has to do with anything. If you're not sure what exactly the server wants, consider writing a test program to send various strings to the server until you know what format it needs to be in.

int TIMEOUT_MILLISEC = 10000;  // = 10 seconds
String postMessage="{}"; //HERE_YOUR_POST_STRING.
HttpParams httpParams = new BasicHttpParams();
HttpConnectionParams.setConnectionTimeout(httpParams, TIMEOUT_MILLISEC);
HttpConnectionParams.setSoTimeout(httpParams, TIMEOUT_MILLISEC);
HttpClient client = new DefaultHttpClient(httpParams);

HttpPost request = new HttpPost(serverUrl);
request.setEntity(new ByteArrayEntity(
    postMessage.toString().getBytes("UTF8")));
HttpResponse response = client.execute(request);

I like the DataTable approach proposed by MusiGenesis above. The nice thing about it is that you can sort by any valid SQL 'order by' string that uses column names, e.g. "x, y desc, z" for 'order by x, y desc, z'. (FWIW, I could not get it to work using column ordinals, e.g. "3,2,1 " for 'order by 3,2,1') I used only integers, but clearly you could add mixed type data into the DataTable and sort it any which way.

In the example below, I first loaded some unsorted integer data into a tblToBeSorted in Sandbox (not shown). With the table and its data already existing, I load it (unsorted) into a 2D integer array, then to a DataTable. The array of DataRows is the sorted version of DataTable. The example is a little odd in that I load my array from the DB and could have sorted it then, but I just wanted to get an unsorted array into C# to use with the DataTable object.

static void Main(string[] args)
{
    SqlConnection cnnX = new SqlConnection("Data Source=r90jroughgarden\\;Initial Catalog=Sandbox;Integrated Security=True");
    SqlCommand cmdX = new SqlCommand("select * from tblToBeSorted", cnnX);
    cmdX.CommandType = CommandType.Text;
    SqlDataReader rdrX = null;
    if (cnnX.State == ConnectionState.Closed) cnnX.Open();

    int[,] aintSortingArray = new int[100, 4];     //i, elementid, planid, timeid

    try
    {
        //Load unsorted table data from DB to array
        rdrX = cmdX.ExecuteReader();
        if (!rdrX.HasRows) return;

        int i = -1;
        while (rdrX.Read() && i < 100)
        {
            i++;
            aintSortingArray[i, 0] = rdrX.GetInt32(0);
            aintSortingArray[i, 1] = rdrX.GetInt32(1);
            aintSortingArray[i, 2] = rdrX.GetInt32(2);
            aintSortingArray[i, 3] = rdrX.GetInt32(3);
        }
        rdrX.Close();

        DataTable dtblX = new DataTable();
        dtblX.Columns.Add("ChangeID");
        dtblX.Columns.Add("ElementID");
        dtblX.Columns.Add("PlanID");
        dtblX.Columns.Add("TimeID");
        for (int j = 0; j < i; j++)
        {
            DataRow drowX = dtblX.NewRow();
            for (int k = 0; k < 4; k++)
            {
                drowX[k] = aintSortingArray[j, k];
            }
            dtblX.Rows.Add(drowX);
        }

        DataRow[] adrowX = dtblX.Select("", "ElementID, PlanID, TimeID");
        adrowX = dtblX.Select("", "ElementID desc, PlanID asc, TimeID desc");

    }
    catch (Exception ex)
    {
        string strErrMsg = ex.Message;
    }
    finally
    {
        if (cnnX.State == ConnectionState.Open) cnnX.Close();
    }
}

There are MANY reasons to use brace initialization, but you should be aware that the initializer_list<> constructor is preferred to the other constructors, the exception being the default-constructor. This leads to problems with constructors and templates where the type T constructor can be either an initializer list or a plain old ctor.

struct Foo {
    Foo() {}

    Foo(std::initializer_list<Foo>) {
        std::cout << "initializer list" << std::endl;
    }

    Foo(const Foo&) {
        std::cout << "copy ctor" << std::endl;
    }
};

int main() {
    Foo a;
    Foo b(a); // copy ctor
    Foo c{a}; // copy ctor (init. list element) + initializer list!!!
}

Assuming you don't encounter such classes there is little reason not to use the intializer list.

A really nicer way would be creating a class (or classes) for the exceptions.

Something like:

class ConfigurationError : public std::exception {
public:
    ConfigurationError();
};

class ConfigurationLoadError : public ConfigurationError {
public:
    ConfigurationLoadError(std::string & filename);
};

The reason is that exceptions are much more preferable than just transferring a string. Providing different classes for the errors, you give developers a chance to handle a particular error in a corresponded way (not just display an error message). People catching your exception can be as specific as they need if you use a hierarchy.

a) One may need to know the specific reason

} catch (const ConfigurationLoadError & ex) {
// ...
} catch (const ConfigurationError & ex) {

a) another does not want to know details

} catch (const std::exception & ex) {

You can find some inspiration on this topic in https://books.google.ru/books?id=6tjfmnKhT24C Chapter 9

Also, you can provide a custom message too, but be careful - it is not safe to compose a message with either std::string or std::stringstream or any other way which can cause an exception.

Generally, there is no difference whether you allocate memory (work with strings in C++ manner) in the constructor of the exception or just before throwing - std::bad_alloc exception can be thrown before the one which you really want.

So, a buffer allocated on the stack (like in Maxim's answer) is a safer way.

It is explained very well at http://www.boost.org/community/error_handling.html

So, the nicer way would be a specific type of the exception and be avoiding composing the formatted string (at least when throwing).

What you are probably really wanting to do here is use the union operator like this:

(select ID from Logo where AccountID = 1 and Rendered = 'True')
  union
  (select ID from Design where AccountID = 1 and Rendered = 'True')
  order by ID limit 0, 51

Here's the docs for it https://dev.mysql.com/doc/refman/5.0/en/union.html

Quicksort with Python

In real life, we should always use the builtin sort provided by Python. However, understanding the quicksort algorithm is instructive.

My goal here is to break down the subject such that it is easily understood and replicable by the reader without having to return to reference materials.

The quicksort algorithm is essentially the following:

1. Select a pivot data point.
2. Move all data points less than (below) the pivot to a position below the pivot - move those greater than or equal to (above) the pivot to a position above it.
3. Apply the algorithm to the areas above and below the pivot

If the data are randomly distributed, selecting the first data point as the pivot is equivalent to a random selection.

Readable example:

First, let's look at a readable example that uses comments and variable names to point to intermediate values:

def quicksort(xs):
    """Given indexable and slicable iterable, return a sorted list"""
    if xs: # if given list (or tuple) with one ordered item or more: 
        pivot = xs[0]
        # below will be less than:
        below = [i for i in xs[1:] if i < pivot] 
        # above will be greater than or equal to:
        above = [i for i in xs[1:] if i >= pivot]
        return quicksort(below) + [pivot] + quicksort(above)
    else: 
        return xs # empty list

To restate the algorithm and code demonstrated here - we move values above the pivot to the right, and values below the pivot to the left, and then pass those partitions to same function to be further sorted.

Golfed:

This can be golfed to 88 characters:

q=lambda x:x and q([i for i in x[1:]if i<=x[0]])+[x[0]]+q([i for i in x[1:]if i>x[0]])

To see how we get there, first take our readable example, remove comments and docstrings, and find the pivot in-place:

def quicksort(xs):
    if xs: 
        below = [i for i in xs[1:] if i < xs[0]] 
        above = [i for i in xs[1:] if i >= xs[0]]
        return quicksort(below) + [xs[0]] + quicksort(above)
    else: 
        return xs

Now find below and above, in-place:

def quicksort(xs):
    if xs: 
        return (quicksort([i for i in xs[1:] if i < xs[0]] )
                + [xs[0]] 
                + quicksort([i for i in xs[1:] if i >= xs[0]]))
    else: 
        return xs

Now, knowing that and returns the prior element if false, else if it is true, it evaluates and returns the following element, we have:

def quicksort(xs):
    return xs and (quicksort([i for i in xs[1:] if i < xs[0]] )
                   + [xs[0]] 
                   + quicksort([i for i in xs[1:] if i >= xs[0]]))

Since lambdas return a single epression, and we have simplified to a single expression (even though it is getting more unreadable) we can now use a lambda:

quicksort = lambda xs: (quicksort([i for i in xs[1:] if i < xs[0]] )
                        + [xs[0]] 
                        + quicksort([i for i in xs[1:] if i >= xs[0]]))

And to reduce to our example, shorten the function and variable names to one letter, and eliminate the whitespace that isn't required.

q=lambda x:x and q([i for i in x[1:]if i<=x[0]])+[x[0]]+q([i for i in x[1:]if i>x[0]])

Note that this lambda, like most code golfing, is rather bad style.

In-place Quicksort, using the Hoare Partitioning scheme

The prior implementation creates a lot of unnecessary extra lists. If we can do this in-place, we'll avoid wasting space.

The below implementation uses the Hoare partitioning scheme, which you can read more about on wikipedia (but we have apparently removed up to 4 redundant calculations per partition() call by using while-loop semantics instead of do-while and moving the narrowing steps to the end of the outer while loop.).

def quicksort(a_list):
    """Hoare partition scheme, see https://en.wikipedia.org/wiki/Quicksort"""
    def _quicksort(a_list, low, high):
        # must run partition on sections with 2 elements or more
        if low < high: 
            p = partition(a_list, low, high)
            _quicksort(a_list, low, p)
            _quicksort(a_list, p+1, high)
    def partition(a_list, low, high):
        pivot = a_list[low]
        while True:
            while a_list[low] < pivot:
                low += 1
            while a_list[high] > pivot:
                high -= 1
            if low >= high:
                return high
            a_list[low], a_list[high] = a_list[high], a_list[low]
            low += 1
            high -= 1
    _quicksort(a_list, 0, len(a_list)-1)
    return a_list

Not sure if I tested it thoroughly enough:

def main():
    assert quicksort([1]) == [1]
    assert quicksort([1,2]) == [1,2]
    assert quicksort([1,2,3]) == [1,2,3]
    assert quicksort([1,2,3,4]) == [1,2,3,4]
    assert quicksort([2,1,3,4]) == [1,2,3,4]
    assert quicksort([1,3,2,4]) == [1,2,3,4]
    assert quicksort([1,2,4,3]) == [1,2,3,4]
    assert quicksort([2,1,1,1]) == [1,1,1,2]
    assert quicksort([1,2,1,1]) == [1,1,1,2]
    assert quicksort([1,1,2,1]) == [1,1,1,2]
    assert quicksort([1,1,1,2]) == [1,1,1,2]

Conclusion

This algorithm is frequently taught in computer science courses and asked for on job interviews. It helps us think about recursion and divide-and-conquer.

Quicksort is not very practical in Python since our builtin timsort algorithm is quite efficient, and we have recursion limits. We would expect to sort lists in-place with list.sort or create new sorted lists with sorted - both of which take a key and reverse argument.

If you want to return to your current working directory:

current_dir=$PWD;cd /path/to/your/command/dir;special command ARGS;cd $current_dir;

1. We are setting a variable current_dir equal to your pwd

list[-1] will retrieve the last element of the list without changing the list. list.pop() will retrieve the last element of the list, but it will mutate/change the original list. Usually, mutating the original list is not recommended.

Alternatively, if, for some reason, you're looking for something less pythonic, you could use list[len(list)-1], assuming the list is not empty.

1. From maven tab click + and choose pom.xml
2. From maven tab click download sources and documentation
3. On project structure(where you can view project files/directories) right click the project you're trying to build and choose Build Module Project Name.
4. From tab Run- Edit Configurations with + add Application and fill the below fields: i. Main Class- Manually choose from Project tab select the main class ii. Use classpath of module - choose the application name iii. Shorten command line - classpath file
5. Now simply run the app.

Yes there is. With .NET 3.5:

int sum = arr.Sum();
Console.WriteLine(sum);

If you're not using .NET 3.5 you could do this:

int sum = 0;
Array.ForEach(arr, delegate(int i) { sum += i; });
Console.WriteLine(sum);

I've modified the version above to run for all tables and support new SQL 2005 data types. It also retains the primary key names. Works only on SQL 2005 (using cross apply).

cross apply
    (SELECT

Update 2: Fixed cases when 1) there is multiple tables with the same name but with different schemas, 2) there is multiple tables having PK constraint with the same name

Specific actions you can do from SQL client and you don't need to restart anything:

If you are behind a proxy server this issue could happen i had the same issue and was solved by: Preferences -> General -> Proxy Settings -> No Proxy.

A different approach, just for kicks:

Console.WriteLine(string.Join("\t", list));

I know this is old, but I thought it might be helpful to show what these functions look like in code. This really illustrates the logic, better than text or a table IMO. In reality they are implemented in C rather than pure Python, but these are equivalent.

def any(iterable):
    for item in iterable:
        if item:
            return True
    return False

def all(iterable):
    for item in iterable:
        if not item:
            return False
    return True

In particular, you can see that the result for empty iterables is just the natural result, not a special case. You can also see the short-circuiting behaviour; it would actually be more work for there not to be short-circuiting.

When Guido van Rossum (the creator of Python) first proposed adding any() and all(), he explained them by just posting exactly the above snippets of code.

select <column list> into <table name> from <source> where <whereclause>

If you want to use arrays as arguments, the following code works in Rails 4:

query = Order.where(uuid: uuids, id: ids)
Order.where(query.where_values.map(&:to_sql).join(" OR "))
#=> Order Load (0.7ms)  SELECT "orders".* FROM "orders" WHERE ("orders"."uuid" IN ('5459eed8350e1b472bfee48375034103', '21313213jkads', '43ujrefdk2384us') OR "orders"."id" IN (2, 3, 4))

Here is how to do this on Windows without third-party tools:

1. Import certificate to the certificate store. In Windows Explorer select "Install Certificate" in context menu. Follow the wizard and accept default options "Local User" and "Automatically".

2. Find your certificate in certificate store. On Windows 10 run the "Manage User Certificates" MMC. On Windows 2013 the MMC is called "Certificates". On Windows 10 by default your certificate should be under "Personal"->"Certificates" node.

3. Export Certificate. In context menu select "Export..." menu:

   Select "Yes, export the private key":

   You will see that .PFX option is enabled in this case:

   Specify password for private key.

Google has a YouTube Android Player API that enables you to incorporate video playback functionality into your Android applications. The API itself is very easy to use and works well. For example, here is how to create a new activity to play a video using the API.

Intent intent = YouTubeStandalonePlayer.createVideoIntent(this, "<<YOUTUBE_API_KEY>>", "<<Youtube Video ID>>", 0, true, false);   
startActivity(intent);

See this for more details.

you should use escape character like this:

printf("\"");

Regardless of the benefits, I would suggest that you always compile your program for the system's default word size (32-bit or 64-bit), since if you compile a library as a 32-bit binary and provide it on a 64-bit system, you will force anyone who wants to link with your library to provide their library (and any other library dependencies) as a 32-bit binary, when the 64-bit version is the default available. This can be quite a nuisance for everyone. When in doubt, provide both versions of your library.

As to the practical benefits of 64-bit... the most obvious is that you get a bigger address space, so if mmap a file, you can address more of it at once (and load larger files into memory). Another benefit is that, assuming the compiler does a good job of optimizing, many of your arithmetic operations can be parallelized (for example, placing two pairs of 32-bit numbers in two registers and performing two adds in single add operation), and big number computations will run more quickly. That said, the whole 64-bit vs 32-bit thing won't help you with asymptotic complexity at all, so if you are looking to optimize your code, you should probably be looking at the algorithms rather than the constant factors like this.

EDIT:
Please disregard my statement about the parallelized addition. This is not performed by an ordinary add statement... I was confusing that with some of the vectorized/SSE instructions. A more accurate benefit, aside from the larger address space, is that there are more general purpose registers, which means more local variables can be maintained in the CPU register file, which is much faster to access, than if you place the variables in the program stack (which usually means going out to the L1 cache).

You are implementing the Click Handler rather than Select Handler. A List by default doesn't suppose to have selection.

What you should change, in your above example, is to

public void onItemClick(AdapterView<?> adapter, View v, int position, long id) {
    MyClass item = (MyClass) adapter.getItem(position);
}

It is not too surprising: the execution plan for the tiny insert is computed once, and then reused 1000 times. Parsing and preparing the plan is quick, because it has only four values to del with. A 1000-row plan, on the other hand, needs to deal with 4000 values (or 4000 parameters if you parameterized your C# tests). This could easily eat up the time savings you gain by eliminating 999 roundtrips to SQL Server, especially if your network is not overly slow.

Use boolalpha to print bool to string.

std::cout << std::boolalpha << b << endl;
std::cout << std::noboolalpha << b << endl;

C++ Reference

Remove these two lines:

xmlHttp.setRequestHeader("Content-length", params.length);
xmlHttp.setRequestHeader("Connection", "close");

XMLHttpRequest isn't allowed to set these headers, they are being set automatically by the browser. The reason is that by manipulating these headers you might be able to trick the server into accepting a second request through the same connection, one that wouldn't go through the usual security checks - that would be a security vulnerability in the browser.

As noted by Mattias Nordqvist in the comments below, you can also select the radio button option "Run whether user is logged on or not". When saving the task, you will be prompted once for the user password. bambams noted that this wouldn't grant System permissions to the process, and also seems to hide the command window.

It's not an obvious solution, but to make a Scheduled Task run in the background, change the User running the task to "SYSTEM", and nothing will appear on your screen.

<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">

<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/" debug="false">

   <appender name="fileAppender" class="org.apache.log4j.RollingFileAppender">
      <param name="Threshold" value="INFO" />

</log4j:configuration>

Log4j can be a bit confusing. So lets try to understand what is going on in this file: In log4j you have two basic constructs appenders and loggers.

Appenders define how and where things are appended. Will it be logged to a file, to the console, to a database, etc.? In this case you are specifying that log statements directed to fileAppender will be put in the file sample.log using the pattern specified in the layout tags. You could just as easily create a appender for the console or the database. Where the console appender would specify things like the layout on the screen and the database appender would have connection details and table names.

Loggers respond to logging events as they bubble up. If an event catches the interest of a specific logger it will invoke its attached appenders. In the example below you have only one logger the root logger - which responds to all logging events by default. In addition to the root logger you can specify more specific loggers that respond to events from specific packages. These loggers can have their own appenders specified using the appender-ref tags or will otherwise inherit the appenders from the root logger. Using more specific loggers allows you to fine tune the logging level on specific packages or to direct certain packages to other appenders.

So what this file is saying is:

1. Create a fileAppender that logs to file sample.log
2. Attach that appender to the root logger.
3. The root logger will respond to any events at least as detailed as 'debug' level
4. The appender is configured to only log events that are at least as detailed as 'info'

The net out is that if you have a logger.debug("blah blah") in your code it will get ignored. A logger.info("Blah blah"); will output to sample.log.

The snippet below could be added to the file above with the log4j tags. This logger would inherit the appenders from <root> but would limit the all logging events from the package org.springframework to those logged at level info or above.

  <!-- Example Package level Logger -->
    <logger name="org.springframework">
        <level value="info"/>
    </logger>   

Return a tuple:

func getTime() -> (Int, Int, Int) {
    ...
    return ( hour, minute, second)
}

Then it's invoked as:

let (hour, minute, second) = getTime()

or:

let time = getTime()
println("hour: \(time.0)")

The time.Parse function does not do Unix timestamps. Instead you can use strconv.ParseInt to parse the string to int64 and create the timestamp with time.Unix:

package main

import (
    "fmt"
    "time"
    "strconv"
)

func main() {
    i, err := strconv.ParseInt("1405544146", 10, 64)
    if err != nil {
        panic(err)
    }
    tm := time.Unix(i, 0)
    fmt.Println(tm)
}

Output:

2014-07-16 20:55:46 +0000 UTC

Playground: http://play.golang.org/p/v_j6UIro7a

Edit:

Changed from strconv.Atoi to strconv.ParseInt to avoid int overflows on 32 bit systems.

PermGen Space stands for memory allocation for Permanent generation All Java immutable objects come under this category, like String which is created with literals or with String.intern() methods and for loading the classes into memory. PermGen Space speeds up our String equality searching.

One more thing you have to keep in mind that the APPEND() method in Pandas doesn't modify the original object. Instead it creates a new one with combined data. Because of involving creation and data buffer, its performance is not well. You'd better use CONCAT() function when doing multi-APPEND operations.

This works for me, It will assign a new branch for detached head :

git checkout new_branch_name detached_head_garbage_name

This is a quick example

plot(rnorm(30), xlab = expression(paste("4"^"th")))

do you mean empty or null, two different things,

if the array is instantiated but empty, then length is correct, if it has not been instantiated then test vs null

You don't need an initializer, unless you're dynamically loading a different image each time. I think doing as much as possible in fxml is more organized. Here is an fxml file that will do what you need.

<?xml version="1.0" encoding="UTF-8"?>

                    />
            </image>
        </ImageView>
    </children>
</AnchorPane>

Specifying the backgroundLoading property in the Image tag is optional, it defaults to false. It's best to set backgroundLoading true when it takes a moment or longer to load the image, that way a placeholder will be used until the image loads, and the program wont freeze while loading.

You haven't said which version you want, but an archive of the JDK 8 source code can be downloaded here, along with JDK 7 and JDK 6.

Additionally you can browse or clone the Mercurial repositories: 8, 7, 6.

Caveats

Here are two worthy caveats from the comments.

Either you want user to be of type User | {} or Partial<User>, or you need to redefine the User type to allow an empty object. Right now, the compiler is correctly telling you that user is not a User. – jcalz

I don't think this should be considered a proper answer because it creates an inconsistent instance of the type, undermining the whole purpose of TypeScript. In this example, the property Username is left undefined, while the type annotation is saying it can't be undefined. – Ian Liu Rodrigues

Answer

One of the design goals of TypeScript is to "strike a balance between correctness and productivity." If it will be productive for you to do this, use Type Assertions to create empty objects for typed variables.

type User = {
    Username: string;
    Email: string;
}

const user01 = {} as User;
const user02 = <User>{};

user01.Email = "[email protected]";

Here is a working example for you.

Given the already proposed options the easiest solution without finding a parent:

var parent = document.createElement("div");
var child = parent.appendChild(document.createElement("a"));
var span = document.createElement("span");

// for IE
if("replaceNode" in child)
  child.replaceNode(span);

// for other browsers
if("replaceWith" in child)
  child.replaceWith(span);

console.log(parent.outerHTML);

Please use

-- turn on statistics IO for IO related 
SET STATISTICS IO ON 
GO

and for time calculation use

SET STATISTICS TIME ON
GO

then It will give result for every query . In messages window near query input window.

This is a paragraph option. Go to Window>Paragraph then a small window will pop up. You will have two buttons on the bottom. One with a arrow on the left of P and one on the right. Select the right one.

What worked for me (youtube-dl version 2018.03.03, ffprobe 0.5, no avprobe, 3.4.1-tessus, in Hi-Sierra/iMac) was:

brew install libav

(thanks to marciovsena's post on GitHub).

I saw elsewhere that libav might be deprecated in the future, but I'll worry about it when we get there.

You can also check like struct_var == (struct{}). This does not allow you to compare to nil but it does check if it is initialized or not. Be careful while using this method. If your struct can have zero values for all of its fields you won't have great time.

package main

import "fmt"

type A struct {
    Name string
}

func main() {
    a := A{"Hello"}
    var b A

    if a == (A{}) {
        fmt.Println("A is empty") // Does not print
    } 

    if b == (A{}) {
        fmt.Println("B is empty") // Prints
    } 
}

A quick and dirty solution I have used is to place the EditText inside of a FrameLayout. The margins of the EditText control the thickness of the border and the border color is determined by the background color of the FrameLayout.

Example:

<FrameLayout
    android:id="@+id/frameLayout"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="#000000">

    <EditText
        android:id="@+id/editText"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_margin="3dp"
        android:background="@android:color/white"
        android:ems="10"
        android:inputType="text"
        android:textSize="24sp" />
</FrameLayout>

But I would recommend, and the vast majority of the time I do, drawables for borders. Elite's answer is what I would go for in that case.

In some OS you need to use new libraries: libmagick++4 libmagick++-dev

You can use:

sudo apt-get install libmagick++4 libmagick++-dev

Select [insert your fields here]

unsigned char* is basically a byte array and should be used to represent raw data rather than a string generally. A unicode string would be represented as wchar_t*

According to the C++ standard a reinterpret_cast between unsigned char* and char* is safe as they are the same size and have the same construction and constraints. I try to avoid reintrepret_cast even more so than const_cast in general.

If static cast fails with what you are doing you may want to reconsider your design because frankly if you are using C++ you may want to take advantage of what the "plus plus" part offers and use string classes and STL (aka std::basic_string might work better for you)

Your @JsonSubTypes declaration does not make sense: it needs to list implementation (sub-) classes, NOT the class itself (which would be pointless). So you need to modify that entry to list sub-class(es) there are; or use some other mechanism to register sub-classes (SimpleModule has something like addAbstractTypeMapping).

From the answer here, spark.sql.shuffle.partitions configures the number of partitions that are used when shuffling data for joins or aggregations.

spark.default.parallelism is the default number of partitions in RDDs returned by transformations like join, reduceByKey, and parallelize when not set explicitly by the user. Note that spark.default.parallelism seems to only be working for raw RDD and is ignored when working with dataframes.

If the task you are performing is not a join or aggregation and you are working with dataframes then setting these will not have any effect. You could, however, set the number of partitions yourself by calling df.repartition(numOfPartitions) (don't forget to assign it to a new val) in your code.

To change the settings in your code you can simply do:

sqlContext.setConf("spark.sql.shuffle.partitions", "300")
sqlContext.setConf("spark.default.parallelism", "300")

Alternatively, you can make the change when submitting the job to a cluster with spark-submit:

./bin/spark-submit --conf spark.sql.shuffle.partitions=300 --conf spark.default.parallelism=300

Put file inside while True like so

while True:
     f = open('torecv.png','wb')
     c, addr = s.accept()     # Establish connection with client.
     print 'Got connection from', addr
     print "Receiving..."
     l = c.recv(1024)
     while (l):
         print "Receiving..."
         f.write(l)
         l = c.recv(1024)
     f.close()
     print "Done Receiving"
     c.send('Thank you for connecting')
     c.close()   

If you want to make multiple operation use

select (sel1.s1+sel2+s2)

(select sum(hours) s1 from resource) sel1
join 
(select sum(hours) s2 from projects-time)sel2
on sel1.s1=sel2.s2

Attach an event listener to the form using .addEventListener() and then call the .preventDefault() method on event:

const element = document.querySelector('form');_x000D_
element.addEventListener('submit', event => {_x000D_
  event.preventDefault();_x000D_
  // actual logic, e.g. validate the form_x000D_
  console.log('Form submission cancelled.');_x000D_
});

<form>_x000D_
  <button type="submit">Submit</button>_x000D_
</form>

I think it's a better solution than defining a submit event handler inline with the onsubmit attribute because it separates webpage logic and structure. It's much easier to maintain a project where logic is separated from HTML. See: Unobtrusive JavaScript.

Using the .onsubmit property of the form DOM object is not a good idea because it prevents you from attaching multiple submit callbacks to one element. See addEventListener vs onclick .

Here is a working demo. For those of you looking for a jQuery plugin, I made one of those too.

jQuery (original answer)

I have found a solution for this in this thread. I was able to modify the info given and mix it with a bit of jQuery to create a totally awesome function to select the text in any element, regardless of browser:

function SelectText(element) {
    var text = document.getElementById(element);
    if ($.browser.msie) {
        var range = document.body.createTextRange();
        range.moveToElementText(text);
        range.select();
    } else if ($.browser.mozilla || $.browser.opera) {
        var selection = window.getSelection();
        var range = document.createRange();
        range.selectNodeContents(text);
        selection.removeAllRanges();
        selection.addRange(range);
    } else if ($.browser.safari) {
        var selection = window.getSelection();
        selection.setBaseAndExtent(text, 0, text, 1);
    }
}

- name: set pkg copy dir name
  set_fact:
    PKG_DIR: >-
      {% if ansible_os_family == "RedHat" %}centos/*.rpm
      {%- elif ansible_distribution == "Ubuntu" %}ubuntu/*.deb
      {%- elif ansible_distribution == "Kylin Linux Advanced Server" %}kylin/*.deb
      {%- else %}{%- endif %}

This should work:

 cat "$API" >> "$CONFIG"

You need to use the >> operator to append to a file. Redirecting with > causes the file to be overwritten. (truncated).

Description

You can use another overload of the DropDownList method. Pick the one you need and pass in a object with your html attributes.

Sample

@Html.DropDownList("CategoryID", null, new { @onchange="location = this.value;" })

You just need to add a jquery selector after the url.

See: http://api.jquery.com/load/

Example straight from the API:

$('#result').load('ajax/test.html #container');

So what that does is it loads the #container element from the specified url.

As it's 2018, use flexbox - no more inline-block whitespace issues:

body {
  margin: 0;
}

#wrapper {
  display: flex;
  height: 200px;
}

#wrapper > div {
  flex-grow: 1;
}

#wrapper > div:first-of-type { background-color: red }
#wrapper > div:nth-of-type(2) { background-color: blue }
#wrapper > div:nth-of-type(3) { background-color: green }

<div id="wrapper">
  <div id="c1"></div>
  <div id="c2"></div>
  <div id="c3"></div>
</div>

Or even CSS grid if you are creating a grid.

body {
  margin: 0;
}

#wrapper {
  display: grid;
  grid-template-columns: repeat(3, 1fr);
  grid-auto-rows: minmax(200px, auto);
}

#wrapper>div:first-of-type { background-color: red }
#wrapper>div:nth-of-type(2) { background-color: blue }
#wrapper>div:nth-of-type(3) { background-color: green }

<div id="wrapper">
  <div id="c1"></div>
  <div id="c2"></div>
  <div id="c3"></div>
</div>

Use CSS calc():

body {
  margin: 0;
}

div {
  height: 200px;
  width: 33.33%; /* as @passatgt mentioned in the comment, for the older browsers fallback */
  width: calc(100% / 3);
  display: inline-block;
}

div:first-of-type { background-color: red }
div:nth-of-type(2) { background-color: blue }
div:nth-of-type(3) { background-color: green }

<div></div><div></div><div></div>

    <label > Upload Photo : </label> 
    <input type="file" id="file" name='file' onChange=" return submitForm();">
    <input type="hidden" id="filecount" value='0'>

Here is Ajax Code:

function submitForm() {

    var fcnt = $('#filecount').val();
    var fname = $('#filename').val();
    var imgclean = $('#file');
    if(fcnt<=5)
    {
    data = new FormData();
    data.append('file', $('#file')[0].files[0]);

    var imgname  =  $('input[type=file]').val();
     var size  =  $('#file')[0].files[0].size;

    var ext =  imgname.substr( (imgname.lastIndexOf('.') +1) );
    if(ext=='jpg' || ext=='jpeg' || ext=='png' || ext=='gif' || ext=='PNG' || ext=='JPG' || ext=='JPEG')

    }).done(function(data) {
       if(data!='FILE_SIZE_ERROR' || data!='FILE_TYPE_ERROR' )
       {
        fcnt = parseInt(fcnt)+1;
        $('#filecount').val(fcnt);
        var img = '<div class="dialog" id ="img_'+fcnt+'" ><img src="<?php echo base_url() ?>/local_cdn/'+data+'"><a href="#" id="rmv_'+fcnt+'" onclick="return removeit('+fcnt+')" class="close-classic"></a></div><input type="hidden" id="name_'+fcnt+'" value="'+data+'">';
        $('#prv').append(img);
        if(fname!=='')
        {
          fname = fname+','+data;
        }else
        {
          fname = data;
        }
         $('#filename').val(fname);
          imgclean.replaceWith( imgclean = imgclean.clone( true ) );
       }
       else
       {
         imgclean.replaceWith( imgclean = imgclean.clone( true ) );
         alert('SORRY SIZE AND TYPE ISSUE');
       }

    });
    return false;
  }//end size
  else

      imgclean.replaceWith( imgclean = imgclean.clone( true ) );//Its for reset the value of file type
    alert('Sorry File size exceeding from 1 Mb');

     imgclean.replaceWith( imgclean = imgclean.clone( true ) );
    alert('Sorry Only you can uplaod JPEG|JPG|PNG|GIF file type ');
  }
  }//end filecount
  else
  {    imgclean.replaceWith( imgclean = imgclean.clone( true ) );
     alert('You Can not Upload more than 6 Photos');
  }
}

Here is PHP code :

$filetype = array('jpeg','jpg','png','gif','PNG','JPEG','JPG');
   foreach ($_FILES as $key )
    {

          $name =time().$key['name'];

          $path='local_cdn/'.$name;
          $file_ext =  pathinfo($name, PATHINFO_EXTENSION);
          if(in_array(strtolower($file_ext), $filetype))
          {
            if($key['name']<1000000)
            {

             @move_uploaded_file($key['tmp_name'],$path);
             echo $name;

            }
           else
           {
               echo "FILE_SIZE_ERROR";
           }
        }
        else
        {
            echo "FILE_TYPE_ERROR";
        }// Its simple code.Its not with proper validation.

Here upload and preview part done.Now if you want to delete and remove image from page and folder both then code is here for deletion. Ajax Part:

function removeit (arg) {
       var id  = arg;
       // GET FILE VALUE
       var fname = $('#filename').val();
       var fcnt = $('#filecount').val();
        // GET FILE VALUE

       $('#img_'+id).remove();
       $('#rmv_'+id).remove();
       $('#img_'+id).css('display','none');

        var dname  =  $('#name_'+id).val();
        fcnt = parseInt(fcnt)-1;
        $('#filecount').val(fcnt);
        var fname = fname.replace(dname, "");
        var fname = fname.replace(",,", "");
        $('#filename').val(fname);
        $.ajax({
          url: 'delete.php',
          type: 'POST',
          data:{'name':dname},
          success:function(a){
            console.log(a);
            }
        });
    } 

Here is PHP part(delete.php):

$path='local_cdn/'.$_POST['name'];

   if(@unlink($path))
   {
     echo "Success";
   }
   else
   {
     echo "Failed";
   }

Use Convert.ToDouble(value) rather than (double)value. It takes an object and supports all of the types you asked for! :)

Also, your method is always returning a string in the code above; I'd recommend having the method indicate so, and give it a more obvious name (public string FormatLargeNumber(object value))

On the Mac: Instead of JAVA_OPTS and MAVEN_OPTS, use _JAVA_OPTIONS instead. This works!

To catch errors with subprocess.check_output(), you can use CalledProcessError. If you want to use the output as string, decode it from the bytecode.

# \return String of the output, stripped from whitespace at right side; or None on failure.
def runls():
    import subprocess
    try:
        byteOutput = subprocess.check_output(['ls', '-a'], timeout=2)
        return byteOutput.decode('UTF-8').rstrip()
    except subprocess.CalledProcessError as e:
        print("Error in ls -a:\n", e.output)
        return None

Update

The solution these days is to use a CardView with support for rounded corners built in.

Original answer*

Another way I found was to mask out your layout by drawing an image over the top of the layout. It might help you. Check out Android XML rounded clipped corners

In addition to existing good answers, note that Jackson 1.9 improved handling by adding "property unification", meaning that ALL annotations from difference parts of a logical property are combined, using (hopefully) intuitive precedence.

In Jackson 1.8 and prior, only field and getter annotations were used when determining what and how to serialize (writing JSON); and only and setter annotations for deserialization (reading JSON). This sometimes required addition of "extra" annotations, like annotating both getter and setter.

With Jackson 1.9 and above these extra annotations are NOT needed. It is still possible to add those; and if different names are used, one can create "split" properties (serializing using one name, deserializing using other): this is occasionally useful for sort of renaming.

Change your positioning a bit:

.container {
    border: 1px solid #DDDDDD;
    width: 200px;
    height: 200px;
    position:relative;
}
.tag {
    float: left;
    position: absolute;
    left: 0px;
    top: 0px;
    background-color: green;
}

jsFiddle example

You need to set relative positioning on the container and then absolute on the inner tag div. The inner tag's absolute positioning will be with respect to the outer relatively positioned div. You don't even need the z-index rule on the tag div.

As Jose answered, screen -d -r should do the trick. This is a combination of two commands, as taken from the man page.

screen -d detaches the already-running screen session, and screen -r reattaches the existing session. By running screen -d -r, you force screen to detach it and then resume the session.

If you use the capital -D -RR, I quote the man page because it's too good to pass up.

Attach here and now. Whatever that means, just do it.

Note: It is always a good idea to check the status of your sessions by means of "screen -list".

You can create functions in react components. It is actually regular ES6 class which inherits from React.Component. Just be careful and bind it to the correct context in onClick event:

export default class Archive extends React.Component { 

    saySomething(something) {
        console.log(something);
    }

    handleClick(e) {
        this.saySomething("element clicked");
    }

    componentDidMount() {
        this.saySomething("component did mount");
    }

    render() {
        return <button onClick={this.handleClick.bind(this)} value="Click me" />;
    }
}

Here’s a combination of the two requirements: track the mouse position, every 100 milliseconds:

var period = 100,
    tracking;

window.addEventListener("mousemove", function(e) {
    if (!tracking) {
        return;
    }

    console.log("mouse location:", e.clientX, e.clientY)
    schedule();
});

schedule();

function schedule() {
    tracking = false;

    setTimeout(function() {
        tracking = true;
    }, period);
}

This tracks & acts on the mouse position, but only every period milliseconds.

    // UILabel:
    let label = UILabel()
    label.frame = CGRectMake(35, 100, 250, 30)
    label.textColor = UIColor.blackColor()
    label.textAlignment = NSTextAlignment.Center
    label.text = "Hello World"
    self.view.addSubview(label)

    // UIButton:
    let btn: UIButton = UIButton(type: UIButtonType.Custom) as UIButton
    btn.frame = CGRectMake(130, 70, 60, 20)
    btn.setTitle("Click", forState: UIControlState.Normal)
    btn.setTitleColor(UIColor.blackColor(), forState: .Normal)
    btn.addTarget(self, action:Selector("clickAction"), forControlEvents: UIControlEvents.TouchUpInside)
    view.addSubview(btn)


    // Button Action:
    @IBAction func clickAction(sender:AnyObject)
    {
        print("Click Action")
    }

Why not like this?

SELECT count(1)
FROM AD_CurrentView
WHERE myColumn=1

By default

1. Primitives are passed by value. Unlikely to Java, string is primitive in PHP
2. Arrays of primitives are passed by value
3. Objects are passed by reference

4. Arrays of objects are passed by value (the array) but each object is passed by reference.

   <?php
   $obj=new stdClass();
   $obj->field='world';
   
   $original=array($obj);
   
   
   function example($hello) {
       $hello[0]->field='mundo'; // change will be applied in $original
       $hello[1]=new stdClass(); // change will not be applied in $original
       $
   }
   
   example($original);
   
   var_dump($original);
   // array(1) { [0]=> object(stdClass)#1 (1) { ["field"]=> string(5) "mundo" } } 
   

Note: As an optimization, every single value is passed as reference until its modified inside the function. If it's modified and the value was passed by reference then, it's copied and the copy is modified.

Left shift <<

This is somehow easy and whenever you use the shift operator, it is always a bit-wise operation, so we can't use it with a double and float operation. Whenever we left shift one zero, it is always added to the least significant bit (LSB).

But in right shift >> we have to follow one additional rule and that rule is called "sign bit copy". Meaning of "sign bit copy" is if the most significant bit (MSB) is set then after a right shift again the MSB will be set if it was reset then it is again reset, means if the previous value was zero then after shifting again, the bit is zero if the previous bit was one then after the shift it is again one. This rule is not applicable for a left shift.

The most important example on right shift if you shift any negative number to right shift, then after some shifting the value finally reach to zero and then after this if shift this -1 any number of times the value will remain same. Please check.

Also, if all you are trying to do is break up the main.go file into multiple files, then just name the other files "package main" as long as you only define the main function in one of those files, you are good to go.

write a button tag and on click function

var x = document.getElementById('codeRefer').innerHTML;
  document.getElementById('codeRefer').innerHTML = x;

write this all in onclick function

If you mean you want to see them like this:

WORKPLACEID NAME       ADDRESS        TELEPHONE
----------- ---------- -------------- ---------
          1 HSBC       Nugegoda Road      43434
          2 HNB Bank   Colombo Road      223423

then in SQL Plus you can set the column widths like this (for example):

column name format a10
column address format a20
column telephone format 999999999

You can also specify the line size and page size if necessary like this:

set linesize 100 pagesize 50

You do this by typing those commands into SQL Plus before running the query. Or you can put these commands and the query into a script file e.g. myscript.sql and run that. For example:

column name format a10
column address format a20
column telephone format 999999999

select name, address, telephone
from mytable;

Simple solution, make a custom control. (this is made in Xamarin android but should port easily to java)

public class EditTextDecimalNumber:EditText
{
    readonly string _numberFormatDecimalSeparator;

    public EditTextDecimalNumber(Context context, IAttributeSet attrs) : base(context, attrs)
    {
        InputType = InputTypes.NumberFlagDecimal;
        TextChanged += EditTextDecimalNumber_TextChanged;
        _numberFormatDecimalSeparator = System.Threading.Thread.CurrentThread.CurrentUICulture.NumberFormat.NumberDecimalSeparator;

        KeyListener = DigitsKeyListener.GetInstance($"0123456789{_numberFormatDecimalSeparator}");
    }

    private void EditTextDecimalNumber_TextChanged(object sender, TextChangedEventArgs e)
    {
        int noOfOccurence = this.Text.Count(x => x.ToString() == _numberFormatDecimalSeparator);
        if (noOfOccurence >=2)
        {
            int lastIndexOf = this.Text.LastIndexOf(_numberFormatDecimalSeparator,StringComparison.CurrentCulture);
            if (lastIndexOf!=-1)
            {
                this.Text = this.Text.Substring(0, lastIndexOf);
                this.SetSelection(this.Text.Length);
            }

        }
    }
}

Since you have wiped out your computer and want to checkout your project again, you could start by doing the below initial settings:

git config --global user.name "Your Name"
git config --global user.email [email protected]

Login to your github account, go to the repository you want to clone, and copy the URL under "Clone with HTTPS".

You can clone the remote repository by using HTTPS, even if you had setup SSH the last time:

git clone https://github.com/username/repo-name.git

NOTE:

If you had setup SSH for your remote repository previously, you will have to add that key to the known hosts ssh file on your PC; if you don't and try to do git clone [email protected]:username/repo-name.git, you will see an error similar to the one below:

Cloning into 'repo-name'...
The authenticity of host 'github.com (192.30.255.112)' can't be established.
RSA key fingerprint is SHA256:nThbg6kXDoJWGl7E1IGOCspZomTxdCARLviMw6E5SY8.
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes
Warning: Permanently added 'github.com,192.30.255.112' (RSA) to the list of known hosts.
[email protected]: Permission denied (publickey).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

Using HTTPS is a easier than SSH in this case.

Hadoop comes with a useful program called distcp for copying large amounts of data to and from Hadoop Filesystems in parallel. The canonical use case for distcp is for transferring data between two HDFS clusters. If the clusters are running identical versions of hadoop, then the hdfs scheme is appropriate to use.

$ hadoop distcp hdfs://namenode1/foo hdfs://namenode2/bar

The data in /foo directory of namenode1 will be copied to /bar directory of namenode2. If the /bar directory does not exist, it will create it. Also we can mention multiple source paths.

Similar to rsync command, distcp command by default will skip the files that already exist. We can also use -overwrite option to overwrite the existing files in destination directory. The option -update will only update the files that have changed.

$ hadoop distcp -update hdfs://namenode1/foo hdfs://namenode2/bar/foo

distcp can also be implemented as a MapReduce job where the work of copying is done by the maps that run in parallel across the cluster. There will be no reducers.

If trying to copy data between two HDFS clusters that are running different versions, the copy will process will fail, since the RPC systems are incompatible. In that case we need to use the read-only HTTP based HFTP filesystems to read from the source. Here the job has to run on destination cluster.

$ hadoop distcp hftp://namenode1:50070/foo hdfs://namenode2/bar

50070 is the default port number for namenode's embedded web server.

The file permission is okay (0777) but i think your on the shared server, so to delete your file correctly use; 1. create a correct path to your file

// delete from folder
$filename = 'test.txt';
$ifile = '/newy/made/link/uploads/'. $filename; // this is the actual path to the file you want to delete.
unlink($_SERVER['DOCUMENT_ROOT'] .$ifile); // use server document root
// your file will be removed from the folder

That small code will do the magic and remove any selected file you want from any folder provided the actual file path is collect.

Here is how I did it!

//create the font

try {
    //create the font to use. Specify the size!
    Font customFont = Font.createFont(Font.TRUETYPE_FONT, new File("Fonts\\custom_font.ttf")).deriveFont(12f);
    GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
    //register the font
    ge.registerFont(customFont);
} catch (IOException e) {
    e.printStackTrace();
} catch(FontFormatException e) {
    e.printStackTrace();
}

//use the font
yourSwingComponent.setFont(customFont);

this can be solved under MacOS X by installing pyqt with brew

you can do this with css3, this blurs the whole element

div (or whatever element) {
  -webkit-filter: blur(5px);
  -moz-filter: blur(5px);
  -o-filter: blur(5px);
  -ms-filter: blur(5px);
  filter: blur(5px);
}

Inner listener class for SWT and plugin development:

${imports:import(org.eclipse.swt.widgets.Listener)}
private class ${className} implements Listener{

    @Override
    public void handleEvent(Event e) {
        final Widget w = e.widget;
    }
}

Just subtract a number:

> as.Date("2009-10-01")
[1] "2009-10-01"
> as.Date("2009-10-01")-5
[1] "2009-09-26"

Since the Date class only has days, you can just do basic arithmetic on it.

If you want to use POSIXlt for some reason, then you can use it's slots:

> a <- as.POSIXlt("2009-10-04")
> names(unclass(as.POSIXlt("2009-10-04")))
[1] "sec"   "min"   "hour"  "mday"  "mon"   "year"  "wday"  "yday"  "isdst"
> a$mday <- a$mday - 6
> a
[1] "2009-09-28 EDT"

I usually do:

sudo bash -c 'whoami; whoami'

You can

1. create a table variable to hold the result set from the stored proc and then
2. insert the output of the stored proc into the table variable, and then
3. use the table variable exactly as you would any other table...

... sql ....

Declare @T Table ([column definitions here])
Insert @T Exec storedProcname params 
Select * from @T Where ...

You can use Trim if you want to remove from start and end.

string stringWithoutNewLine = "\n\nHello\n\n".Trim();

You can also use this

str_repeat("\x20", $numberOfRepeats);

If the language isn't a problem (any sandboxed scripted one) then there's LUA for .NET. The Silverlight version of the .NET framework is also sandboxed afaik.

Had the issue like this image.

Tried a few solutions. But found that even if it's same project, when it's on other one's working place, it's totally fine. No extra settings needed. So we guessed it's an enviroment issue. We tried changing JDK version, IDE but didn't work. it took about 4 hours for investigation, until we tried the top-rated answer. I didn't find the error mentioned in that answer but I found via my browser about HTTP URL (lock) that there was a certification of Charles. Then I realized my charles was on all the time. As long as I turned that off, it's working all fine.

So I left my experience that could be helpful for your case.

A very simple solution is to search your file(s) for non-ascii characters using a regular expression. This will nicely highlight all the spots where they are found with a border.

Search for [^\x00-\x7F] and check the box for Regex.

The result will look like this (in dark mode):
