If you are on macOS and are not using NVM, the simplest way is to run the installer that comes from node.js web site. It it clever enough to manage substitution of your current installation with the new one, even if it is an older one. At least this worked for me.

With .Net Framework 4.5 (using ZipArchive):

using (ZipArchive zip = ZipFile.Open(zipfile, ZipArchiveMode.Read))
    foreach (ZipArchiveEntry entry in zip.Entries)
        if(entry.Name == "myfile")
            entry.ExtractToFile("myfile");

Find "myfile" in zipfile and extract it.

To answer your question: no, it's not possible to have multiple versions of IE (if that is what you meant) installed in a 'normal' way (i.e. not a hack, a sandbox or a VM etc). It's perfectly ok to have multiple browsers of different types installed on the same machine, such as IE8, Firefox 3 and Chrome all at once.

SandboxIE should allow you to install multiple versions of IE side-by-side (as well as other software), and this is less hassle than going down the virtual machine route.

However, from a QA point of view I'd strongly recommend installing different versions on different machines as the best option from a testing point of view. This will give you the most realistic testing environment. If you don't have the hardware for that, then virtual machines are the next best option as mentioned in some of the other answers.

I prefer (keydown.enter)="mySubmit()" because there won't be added a line break if the cursor was somewhere within a <textarea> but not at its end.

You can use use findFragmentById in FragmentManager.

Since you are using the Support library (you are extending FragmentActivity) you can use:

getSupportFragmentManager().findFragmentById(R.id.pageview)

If you are not using the support library (so you are on Honeycomb+ and you don't want to use the support library):

getFragmentManager().findFragmentById(R.id.pageview)

Please consider that using the support library is recommended even on Honeycomb+.

Use Is Null

select * from tblName where clmnName is null    

I don't think they are reprinting paper books each year. The copyright of the year when the book was printed is valid in all next years.

The same principle should apply to web pages, too. However "the year when website was created" is a bit different. So, if you make changes to your web site - you are not done yet. Hence, when updating the site, you may want to update the copyright year.

Well, I don't have a function in python but I have a function in C which you can easily convert to python, in the below c function extended euclidian algorithm is used to calculate inverse mod.

int imod(int a,int n){
int c,i=1;
while(1){
    c = n * i + 1;
    if(c%a==0){
        c = c/a;
        break;
    }
    i++;
}
return c;}

Python Function

def imod(a,n):
  i=1
  while True:
    c = n * i + 1;
    if(c%a==0):
      c = c/a
      break;
    i = i+1

  return c

Reference to the above C function is taken from the following link C program to find Modular Multiplicative Inverse of two Relatively Prime Numbers

Use direct cast string s = (string) o; if in the logical context of your app string is the only valid type. With this approach, you will get InvalidCastException and implement the principle of Fail-fast. Your logic will be protected from passing the invalid type further or get NullReferenceException if used as operator.

If the logic expects several different types cast string s = o as string; and check it on null or use is operator.

New cool feature have appeared in C# 7.0 to simplify cast and check is a Pattern matching:

if(o is string s)
{
  // Use string variable s
}

or

switch (o)
{
  case int i:
     // Use int variable i
     break;
  case string s:
     // Use string variable s
     break;
 }

I'm guessing that you are running Eclipse Mars, or an even earlier release. You need to upgrade to Eclipse Neon or later

If you have a github account and don't want to download software, you can export to github, then download a zip from github.

You'd better create some class for each item instead of using anonymous objects. And in object you're serializing you should have array of those items. E.g.:

public class Item
{
    public string name { get; set; }
    public string index { get; set; }
    public string optional { get; set; }
}

public class RootObject
{
    public List<Item> items { get; set; }
}

Usage:

var objectToSerialize = new RootObject();
objectToSerialize.items = new List<Item> 
                          {
                             new Item { name = "test1", index = "index1" },
                             new Item { name = "test2", index = "index2" }
                          };

And in the result you won't have to change things several times if you need to change data-structure.

p.s. Here's very nice tool for complex jsons

If you are using Guava, you statically import newArrayList method from Lists class:

List<String> l = newArrayList(setOfAuthors);

For example in my CentOS

sudo gedit /etc/mysql/my.cnf

comment out the following lines

#bind-address = 127.0.0.1

then

sudo service mysqld restart

Refer django docs on static files.

In settings.py:

import os
CURRENT_PATH = os.path.abspath(os.path.dirname(__file__).decode('utf-8'))

MEDIA_ROOT = os.path.join(CURRENT_PATH, 'media')

MEDIA_URL = '/media/'

STATIC_ROOT = 'static/'

STATIC_URL = '/static/'

STATICFILES_DIRS = (
                    os.path.join(CURRENT_PATH, 'static'),
)

Then place your js and css files static folder in your project. Not in media folder.

In views.py:

from django.shortcuts import render_to_response, RequestContext

def view_name(request):
    #your stuff goes here
    return render_to_response('template.html', locals(), context_instance = RequestContext(request))

In template.html:

<link rel="stylesheet" type="text/css" href="{{ STATIC_URL }}css/style.css" />
<script type="text/javascript" src="{{ STATIC_URL }}js/jquery-1.8.3.min.js"></script>

In urls.py:

from django.conf import settings
urlpatterns += patterns('',
    url(r'^media/(?P<path>.*)$', 'django.views.static.serve', {'document_root': settings.MEDIA_ROOT, 'show_indexes': True}),
)

Misspellings are irritating, aren't they? Check your spelling of empty, but then also try this:

#!/bin/bash -e

if [ -s diff.txt ]
then
        rm -f empty.txt
        touch full.txt
else
        rm -f full.txt
        touch empty.txt
fi

I like shell scripting a lot, but one disadvantage of it is that the shell cannot help you when you misspell, whereas a compiler like your C++ compiler can help you.

Notice incidentally that I have swapped the roles of empty.txt and full.txt, as @Matthias suggests.

Try float property. Here's an example: http://jsfiddle.net/mLmHR/

Both classes Rectangle and Ellipse need to override both of the abstract methods.

To work around this, you have 3 options:

• Add the two methods
• Make each class that extends Shape abstract

• Have a single method that does the function of the classes that will extend Shape, and override that method in Rectangle and Ellipse, for example:

  abstract class Shape {
      // ...
      void draw(Graphics g);
  }
  

And

    class Rectangle extends Shape {
        void draw(Graphics g) {
            // ...
        }
    }

Finally

    class Ellipse extends Shape {
        void draw(Graphics g) {
            // ...
        }
    }

And you can switch in between them, like so:

    Shape shape = new Ellipse();
    shape.draw(/* ... */);

    shape = new Rectangle();
    shape.draw(/* ... */);

Again, just an example.

if you are in dev mode with not valid certificate, why not just set weClient.setUseInsecureSSL(true). works for me

Just spicing up the shell script above to delete older files but with logging and calculation of elapsed time

#!/bin/bash

path="/data/backuplog/"
timestamp=$(date +%Y%m%d_%H%M%S)    
filename=log_$timestamp.txt    
log=$path$filename
days=7

START_TIME=$(date +%s)

find $path -maxdepth 1 -name "*.txt"  -type f -mtime +$days  -print -delete >> $log

echo "Backup:: Script Start -- $(date +%Y%m%d_%H%M)" >> $log


... code for backup ...or any other operation .... >> $log


END_TIME=$(date +%s)

ELAPSED_TIME=$(( $END_TIME - $START_TIME ))


echo "Backup :: Script End -- $(date +%Y%m%d_%H%M)" >> $log
echo "Elapsed Time ::  $(date -d 00:00:$ELAPSED_TIME +%Hh:%Mm:%Ss) "  >> $log

The code adds a few things.

• log files named with a timestamp
• log folder specified
• find looks for *.txt files only in the log folder
• type f ensures you only deletes files
• maxdepth 1 ensures you dont enter subfolders
• log files older than 7 days are deleted ( assuming this is for a backup log)
• notes the start / end time
• calculates the elapsed time for the backup operation...

Note: to test the code, just use -print instead of -print -delete. But do check your path carefully though.

Note: Do ensure your server time is set correctly via date - setup timezone/ntp correctly . Additionally check file times with 'stat filename'

Note: mtime can be replaced with mmin for better control as mtime discards all fractions (older than 2 days (+2 days) actually means 3 days ) when it deals with getting the timestamps of files in the context of days

-mtime +$days  --->  -mmin  +$((60*24*$days))

You've got one truly marvelous answer from ray023, but your comment that it's probably overkill is apt. For a "lighter" version....

Block 1 is, IMHO, bad practice. As already pointed out by osknows, mixing error-handling with normal-path code is Not Good. For one thing, if a new error is thrown while there's an Error condition in effect you will not get an opportunity to handle it (unless you're calling from a routine that also has an error handler, where the execution will "bubble up").

Block 2 looks like an imitation of a Try/Catch block. It should be okay, but it's not The VBA Way. Block 3 is a variation on Block 2.

Block 4 is a bare-bones version of The VBA Way. I would strongly advise using it, or something like it, because it's what any other VBA programmer inherting the code will expect. Let me present a small expansion, though:

Private Sub DoSomething()
On Error GoTo ErrHandler

'Dim as required

'functional code that might throw errors

ExitSub:
    'any always-execute (cleanup?) code goes here -- analagous to a Finally block.
    'don't forget to do this -- you don't want to fall into error handling when there's no error
    Exit Sub

ErrHandler:
    'can Select Case on Err.Number if there are any you want to handle specially

    'display to user
    MsgBox "Something's wrong: " & vbCrLf & Err.Description

    'or use a central DisplayErr routine, written Public in a Module
    DisplayErr Err.Number, Err.Description

    Resume ExitSub
    Resume
End Sub

Note that second Resume. This is a trick I learned recently: It will never execute in normal processing, since the Resume <label> statement will send the execution elsewhere. It can be a godsend for debugging, though. When you get an error notification, choose Debug (or press Ctl-Break, then choose Debug when you get the "Execution was interrupted" message). The next (highlighted) statement will be either the MsgBox or the following statement. Use "Set Next Statement" (Ctl-F9) to highlight the bare Resume, then press F8. This will show you exactly where the error was thrown.

As to your objection to this format "jumping around", A) it's what VBA programmers expect, as stated previously, & B) your routines should be short enough that it's not far to jump.

In Oracle, the PL/SQL and SQL engines maintain some separation. When you execute a SQL statement within PL/SQL, it is handed off to the SQL engine, which has no knowledge of PL/SQL-specific structures like INDEX BY tables.

So, instead of declaring the type in the PL/SQL block, you need to create an equivalent collection type within the database schema:

CREATE OR REPLACE TYPE array is table of number;
/

Then you can use it as in these two examples within PL/SQL:

SQL> l
  1  declare
  2    p  array := array();
  3  begin
  4    for i in (select level from dual connect by level < 10) loop
  5      p.extend;
  6      p(p.count) := i.level;
  7    end loop;
  8    for x in (select column_value from table(cast(p as array))) loop
  9       dbms_output.put_line(x.column_value);
 10    end loop;
 11* end;
SQL> /
1
2
3
4
5
6
7
8
9

PL/SQL procedure successfully completed.

  2    p  array := array();

  6       dbms_output.put_line(x.column_value);
  7    end loop;
  8* end;

Additional example based on comments

Based on your comment on my answer and on the question itself, I think this is how I would implement it. Use a package so the records can be fetched from the actual table once and stored in a private package global; and have a function that returns an open ref cursor.

CREATE OR REPLACE PACKAGE p_cache AS
  FUNCTION get_p_cursor RETURN sys_refcursor;
END p_cache;
/

CREATE OR REPLACE PACKAGE BODY p_cache AS

  cache_array  array;

  FUNCTION get_p_cursor RETURN sys_refcursor IS
    pCursor  sys_refcursor;
  BEGIN
    OPEN pCursor FOR SELECT * from TABLE(CAST(cache_array AS array));
    RETURN pCursor;
  END get_p_cursor;

  -- Package initialization runs once in each session that references the package
  BEGIN
    SELECT level BULK COLLECT INTO cache_array FROM dual CONNECT BY LEVEL < 10;
  END p_cache;
/

The closest option available is

[\u\l]+

which matches a sequence of uppercase and lowercase letters. However, it is not supported by all editors/languages, so it is probably safer to use

[a-zA-Z]+

as other users suggest

Can we make an Android NFC as the tag which an NFC reader will get data from?

The Nexus S supports peer-to-peer mode, which as its name implies, causes one phone to act as a tag which another phone can read. There was a really good Google I/O session on NFC this year. I would recommended watching it if you're at all interested in NFC.

Check this

ps -ef | grep shellscripname.sh

You can also find your running process in

ps -ef

Ah, that would be because RegExp is not jQuery. :)

Try this page. jQuery.attr doesn't return a String so that would certainly cause in this regard. Fortunately I believe you can just use .text() to return the String representation.

Something like:

$("li").val("title").search(/sometext/i));

I am on Windows 10, I had the problem with a new fresh installation of Anaconda on python 3.7.4, this post on github solved my problem:

( source: https://github.com/conda/conda/issues/8273)

I cite:

" My workaround: I have copied the following files

libcrypto-1_1-x64.*
libssl-1_1-x64.*

from D:\Anaconda3\Library\bin to D:\Anaconda3\DLLs.

And it works as a charm! "

I dont know about XamGrid but that's what i'll do with a standard wpf DataGrid:

<DataGrid>
    <DataGrid.Columns>
        <DataGridTemplateColumn>
            <DataGridTemplateColumn.CellTemplate>
                <DataTemplate>
                    <TextBlock Text="{Binding DataContext.MyProperty, RelativeSource={RelativeSource AncestorType=MyUserControl}}"/>
                </DataTemplate>
            </DataGridTemplateColumn.CellTemplate>
            <DataGridTemplateColumn.CellEditingTemplate>
                <DataTemplate>
                    <TextBox Text="{Binding DataContext.MyProperty, RelativeSource={RelativeSource AncestorType=MyUserControl}}"/>
                </DataTemplate>
            </DataGridTemplateColumn.CellEditingTemplate>
        </DataGridTemplateColumn>
    </DataGrid.Columns>
</DataGrid>

Since the TextBlock and the TextBox specified in the cell templates will be part of the visual tree, you can walk up and find whatever control you need.

If you choose not to use String.format, the other option is the + binary operator

String str = "Step " + a + " of " + b;

This is the equivalent of

new StringBuilder("Step ").append(String.valueOf(1)).append(" of ").append(String.valueOf(2));

Whichever you use is your choice. StringBuilder is faster, but the speed difference is marginal. I prefer to use the + operator (which does a StringBuilder.append(String.valueOf(X))) and find it easier to read.

On newer versions of Android, I was receiving this error because the adapter was still discovering when I attempted to connect to the socket. Even though I called the cancelDiscovery method on the Bluetooth adapter, I had to wait until the callback to the BroadcastReceiver's onReceive() method was called with the action BluetoothAdapter.ACTION_DISCOVERY_FINISHED.

Once I waited for the adapter to stop discovery, then the connect call on the socket succeeded.

If I understand correctly, you need to convert the type (char value) that you store in Building list to the type (enum) that you store in buildingStatus list.

(For each status in the Building list//character value//, does the status exists in the buildingStatus list//enum value//)

public static IQueryable<Building> WithStatus(this IQueryable<Building> qry,  
IList<BuildingStatuses> buildingStatus) 
{ 
    return from v in qry
           where ContainsStatus(v.Status)
           select v;
} 


private bool ContainsStatus(v.Status)
{
    foreach(Enum value in Enum.GetValues(typeof(buildingStatus)))
    {
        If v.Status == value.GetCharValue();
            return true;
    }

    return false;
}

.eq() -An integer indicating the 0-based position of the element.

Ex:

Consider a page with a simple list on it:

<ul>
<li>list item 1</li>
<li>list item 2</li>
<li>list item 3</li>
<li>list item 4</li>
</ul>

We can apply this method to the set of list items:

$( "li" ).eq( 2 ).css( "background-color", "red" );

For more information : .eq()

I tried replacing value with Value and it worked out. It has set the value in input tag now.

There's some proposition over the web (and this page) to use ViewConfiguration.getScaledTouchSlop() to have a device-scaled value for SWIPE_MIN_DISTANCE.

getScaledTouchSlop() is intended for the "scrolling threshold" distance, not swipe. The scrolling threshold distance has to be smaller than a "swing between page" threshold distance. For example, this function returns 12 pixels on my Samsung GS2, and the examples quoted in this page are around 100 pixels.

With API Level 8 (Android 2.2, Froyo), you've got getScaledPagingTouchSlop(), intended for page swipe. On my device, it returns 24 (pixels). So if you're on API Level < 8, I think "2 * getScaledTouchSlop()" should be the "standard" swipe threshold. But users of my application with small screens told me that it was too few... As on my application, you can scroll vertically, and change page horizontally. With the proposed value, they sometimes change page instead of scrolling.

Put 0 as default in SQL or add 0 into your area of table

Something like (Found at Delete All Procedures from a database using a Stored procedure in SQL Server).

Just so by the way, this seems like a VERY dangerous thing to do, just a thought...

declare @procName varchar(500)
declare cur cursor 

for select [name] from sys.objects where type = 'p'
open cur
fetch next from cur into @procName
while @@fetch_status = 0
begin
    exec('drop procedure [' + @procName + ']')
    fetch next from cur into @procName
end
close cur
deallocate cur

You should put CSS in the <head> because that's what the specification says do to.

If you have more than one CSS file, they will be loaded in the order you put them in the code. If there is style in the second CSS file, it overwrites the style in the first; That will happen by design. Thus, Cascading Style Sheets.

Most browser will still effectivly render CSS files out of the head, but your code is not semantically correct.

You can use JavaScript file links anywhere on the document. There are different reasons to use some in the <head> and some elsewhere on the page. (For example, Google analytic code is instructed to be put at the bottom.)

I had this issue and tried many things but still din't work. Eventually I decided to generate another SSH KEY and boom - it worked. Follow this article by github to guide you on how to generate your SSH KEY.

Lastly don't forget to add it to your github settings. Click here for a guide on how to add your SSH KEY to your github account.

You can define a method in spec_helper.rb that sends a message both to Rails.logger.info and to puts and use that for debugging:

def log_test(message)
    Rails.logger.info(message)
    puts message
end

Having learned of this feature only just now while reading your question, I can only speculate. This seems to provide several advantages over a file-level static variable:

• Anonymous namespaces can be nested within one another, providing multiple levels of protection from which symbols can not escape.
• Several anonymous namespaces could be placed in the same source file, creating in effect different static-level scopes within the same file.

I'd be interested in learning if anyone has used anonymous namespaces in real code.

If they are two integers you can try a quick and dirty trick: Map<String, ?> using the key as i+"#"+j.

If the key i+"#"+j is the same as j+"#"+i try min(i,j)+"#"+max(i,j).

break ends the loop that it is currently in. So, you are only ever checking if it divisible by 2, giving you all odd numbers.

for num in range(2,101):
    for i in range(2,num):
        if (num%i==0):
            break
    else:
        print(num)

that being said, there are much better ways to find primes in python than this.

for num in range(2,101):
    if is_prime(num):
        print(num)

def is_prime(n):
    for i in range(2, int(math.sqrt(n)) + 1):
        if n % i == 0:
            return False
    return True

The reason being you can not access protected member data through the instance of the class.

Reason why it is not allowed is explained in this blog

A save method to determine the width and height unit of any element (no padding, no margin) is the following:

let height = parseFloat(style.height.replace("px", ""));

Consider above program, in this program I want to pass 3 no's from Command Line, to do so.

Step 1 : Right Click on Cup and Saucer icon, u'll see this window

Step 2: Click on Properties

Step 3: Click Run _> Arguments _> type three no's eg. 32 98 16 then click OK. Plz add space between two arguments. See here

Step 4: Run the Program by using F6.

You could use the following to replace the first occurrence of a word within the body of the page:

var replaced = $("body").html().replace('-9o0-9909','The new string');
$("body").html(replaced);

If you wanted to replace all occurrences of a word, you need to use regex and declare it global /g:

var replaced = $("body").html().replace(/-1o9-2202/g,'The ALL new string');
$("body").html(replaced);

If you wanted a one liner:

$("body").html($("body").html().replace(/12345-6789/g,'<b>abcde-fghi</b>'));

You are basically taking all of the HTML within the <body> tags of the page into a string variable, using replace() to find and change the first occurrence of the found string with a new string. Or if you want to find and replace all occurrences of the string introduce a little regex to the mix.

See a demo here - look at the HTML top left to see the original text, the jQuery below, and the output to the bottom right.

Lapack is a Linear Algebra package which is used by R (actually it's used everywhere) underneath solve(), dgesv spits this kind of error when the matrix you passed as a parameter is singular.

As an addendum: dgesv performs LU decomposition, which, when using your matrix, forces a division by 0, since this is ill-defined, it throws this error. This only happens when matrix is singular or when it's singular on your machine (due to approximation you can have a really small number be considered 0)

I'd suggest you check its determinant if the matrix you're using contains mostly integers and is not big. If it's big, then take a look at this link.

You need to run the script like this:

groovy helloworld.groovy

import codecs

fichier = codecs.open(filePath, "r", encoding="utf-8")

 ...

fichierTemp = codecs.open("tempASCII", "w", encoding="ascii", errors="ignore")

Step 1: Go to Tools -> Preferences

Step 2: Select Database -> NLS

Step 3: Go to Date Format and Enter DD-MON-RR HH24: MI: SS

Step 4: Click OK.

On mac use KeyChain -> Login -> Password: change password

• On the front properties page of the variable script, amend the ReadOnlyVariables (or ReadWriteVariables) property and select the variables you are interested in. This will enable the selected variables within the script task

• Within code you will now have access to read the variable as

  string myString = Variables.MyVariableName.ToString();

TL;DR

In the first case with set encoding=utf-8, you'll change the output encoding that is shown in the terminal.

In the second case with set fileencoding=utf-8, you'll change the output encoding of the file that is written.

As stated by @Dennis, you can set them both in your ~/.vimrc if you always want to work in utf-8.

More details

From the wiki of VIM about working with unicode

"encoding sets how vim shall represent characters internally. Utf-8 is necessary for most flavors of Unicode."

"fileencoding sets the encoding for a particular file (local to buffer); :setglobal sets the default value. An empty value can also be used: it defaults to same as 'encoding'. Or you may want to set one of the ucs encodings, It might make the same disk file bigger or smaller depending on your particular mix of characters. Also, IIUC, utf-8 is always big-endian (high bit first) while ucs can be big-endian or little-endian, so if you use it, you will probably need to set 'bomb" (see below)."

Not Sure which version of selenium you are referring to, however some commands in selenium * can now do this: http://release.seleniumhq.org/selenium-core/0.8.0/reference.html

Or just put this in a Javascript file and have a good day :)

String.prototype.includes = function (str) {

  if (this.indexOf(str) !== -1) {
    returnValue = true;
  }

  return returnValue;

If you're doing this in Drupal and use the Form API to change the #type from text to 'hidden' in hook_form_alter (for example), be advised that the output HTML will have different (or omitted) DIV wrappers, IDs and class names.

I just tested this and it works fine

var d = new Date(1441121836000);

The data object has a constructor which takes milliseconds as an argument.

You can also take a look at LineNumberReader, subclass of BufferedReader. Along with the readline method, it also has setter/getter methods to access line number. Very useful to keep track of the number of lines read, while reading data from file.

Try with the following code to get width and height of screen

int widthOfscreen =0;
int heightOfScreen = 0;
DisplayMetrics dm = new DisplayMetrics();
        try {
            ((Activity) context).getWindowManager().getDefaultDisplay()
                    .getMetrics(dm);
        } catch (Exception ex) {
        }
         widthOfscreen  = dm.widthPixels;
heightOfScreen  = dm.heightPixels;

In general, a condition in the WHERE clause of an SQL query can reference only a single row. The context of a WHERE clause is evaluated before any order has been defined by an ORDER BY clause, and there is no implicit order to an RDBMS table.

You can use a derived table to join each row to the group of rows with a lesser id value, and produce the sum of each sum group. Then test where the sum meets your criterion.

CREATE TABLE MyTable ( id INT PRIMARY KEY, cash INT );

INSERT INTO MyTable (id, cash) VALUES
  (1, 200), (2, 301), (3, 101), (4, 700);

SELECT s.*
FROM (
  SELECT t.id, SUM(prev.cash) AS cash_sum
  FROM MyTable t JOIN MyTable prev ON (t.id > prev.id)
  GROUP BY t.id) AS s
WHERE s.cash_sum >= 500
ORDER BY s.id
LIMIT 1;

Output:

+----+----------+
| id | cash_sum |
+----+----------+
|  3 |      501 |
+----+----------+

I've been using Chilkat's native SFTP library ( http://www.chilkatsoft.com/ssh-sftp-component.asp ) for a couple of months now and it's working great. Been using it in a nightly job to download large files and do private key authentication. Only problem that I had was getting the 64bit version to work on windows server 2008, I needed to install vcredist_x64.exe ( http://www.microsoft.com/download/en/details.aspx?id=14632 ) on my server.

To anybody coming to this thread after hours of banging your head against a wall. I solved this error by changing

create table `group`(
    id char(19) primary key
);

to

create table if not exists `group`(
    id char(19) primary key
);

in my schema.sql file in the resources directory.

you must have record in table or array record in database.

example:

SELECT * FROM tabel_record
WHERE table_record.fieldName IN (SELECT fieldName FROM table_reference);

Cinn's answer is great, but there's one thing wrong with it.

The PreferredSize widget will start immediately at the top of the screen, without accounting for the status bar, so some of its height will be shadowed by the status bar's height. This also accounts for the side notches.

The solution: Wrap the preferredSize's child with a SafeArea

appBar: PreferredSize(
  //Here is the preferred height.
  preferredSize: Size.fromHeight(50.0),
  child: SafeArea(
    child: AppBar(
      flexibleSpace: ...
    ),
  ),
),

If you don't wanna use the flexibleSpace property, then there's no need for all that, because the other properties of the AppBar will account for the status bar automatically.

For those of you out there that are encountering this, use the time.RFC3339 versus the string constant of "2006-01-02T15:04:05.000Z". And here is the reason why:

regDate := "2007-10-09T22:50:01.23Z"

layout1 := "2006-01-02T15:04:05.000Z"
t1, err := time.Parse(layout1, regDate)

if err != nil {
    fmt.Println("Static format doesn't work")
} else {
    fmt.Println(t1)
}

layout2 := time.RFC3339
t2, err := time.Parse(layout2, regDate)

if err != nil {
    fmt.Println("RFC format doesn't work") // You shouldn't see this at all
} else {
    fmt.Println(t2)
}

This will produce the following result:

Static format doesn't work

Here is the Playground Link

While I do love using CHECKSUM, I feel that a better way to go is using NEWID(), just because you don't have to go through a complicated math to generate simple numbers .

ROUND( 1000 *RAND(convert(varbinary, newid())), 0)

You can replace the 1000 with whichever number you want to set as the limit, and you can always use a plus sign to create a range, let's say you want a random number between 100 and 200, you can do something like :

100 + ROUND( 100 *RAND(convert(varbinary, newid())), 0)

Putting it together in your query :

UPDATE CattleProds 
SET SheepTherapy= ROUND( 1000 *RAND(convert(varbinary, newid())), 0)
WHERE SheepTherapy IS NULL

In my case, the issue occurred after I switched from a git branch to another, references to some old files remained in the scripts inside "node_modules/.cache" directory.
Deleting "node_modules", "build" directories and "package-lock.json" file then issuing "npm install" command has fixed the issue for me

How about this one-liner?

var isAndroid = /(android)/i.test(navigator.userAgent);

The i modifier is used to perform case-insensitive matching.

Technique taken from Cordova AdMob test project: https://github.com/floatinghotpot/cordova-admob-pro/wiki/00.-How-To-Use-with-PhoneGap-Build

1. Open up a terminal
2. cd <ANDROID_SDK_PATH> (for me on Windows cd C:\Users\Willi\AppData\Local\Android\sdk)
3. cd platform-tools
4. adb shell (this works only if only one emulator is running)
5. cd data/data
6. su (gain super user privileges)
7. cd <PACKAGE_NAME>/databases
8. sqlite3 <DB_NAME>
9. issue SQL statements (important: terminate them with ;, otherwise the statement is not issued and it breaks to a new line instead.)

Note: Use ls (Linux) or dir (Windows) if you need to list directory contents.

If you dont want to hard-code the cell addresses you can use the ROW() function.

eg: =AVERAGE(INDIRECT("A" & ROW()), INDIRECT("C" & ROW()))

Its probably not the best way to do it though! Using Auto-Fill and static columns like @JaiGovindani suggests would be much better.

I know I am late to the show with this one, but I used this - pretty simple approach. This allows you to get the 60 minute slices without any rounding issues.

Select 
   CONCAT( 
            Format(endtime,'yyyy-MM-dd_HH:'),  
            LEFT(Format(endtime,'mm'),1),
            '0' 
          ) as [Time-Slice]

You need to loop through the list and use end=" "to keep it on one line

names = ["Sam", "Peter", "James", "Julian", "Ann"]
    index=0
    for name in names:
        print(names[index], end=", ")
        index += 1

I work with gcc 7.2. I specifically needed a function to be non-inlined, because it had to be instantiated in a library. I tried the __attribute__((noinline)) answer, as well as the asm("") answer. Neither one solved the problem.

Finally, I figured that defining a static variable inside the function will force the compiler to allocate space for it in the static variable block, and to issue an initialization for it when the function is first called.

This is sort of a dirty trick, but it works.

In an attempt to solve a similar situation I've come across this example and adapted it. It uses JQUERY UI Dialog as Nikhil D suggested. Here is a look at the code:

HTML:

<link href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.6/themes/smoothness/jquery-ui.css" rel="stylesheet"/>
<input type="button" id="box" value="Confirm the thing?" />
<div id="dialog-confirm"></div>

JavaScript:

$('#box').click(function buttonAction() {
  $("#dialog-confirm").html("Do you want to do the thing?");

  // Define the Dialog and its properties.
  $("#dialog-confirm").dialog({
    resizable: false,
    modal: true,
    title: "Do the thing?",
    height: 250,
    width: 400,
    buttons: {
      "Yes": function() {
        $(this).dialog('close');
        alert("Yes, do the thing");
      },
      "No": function() {
        $(this).dialog('close');
        alert("Nope, don't do the thing");
      }
    }
  });
});

$('#box').click(buttonAction);

I have a few more tweaks I need to do to make this example work for my application. Will update this if I see it fit into the answer. Hope this helps someone.

int n;//say 12345
string s;
scanf("%d",&n);
sprintf(s,"%5d",n);

Now you can access each digit via s[0], s[1], etc

I recommend not doing this...

What you are describing is not a comprehension.

PEP 8 Style Guide for Python Code, which I do recommend, has this to say on compound statements:

• Compound statements (multiple statements on the same line) are generally discouraged.

Yes:

      if foo == 'blah':
          do_blah_thing()
      do_one()
      do_two()
      do_three()

Rather not:

      if foo == 'blah': do_blah_thing()
      do_one(); do_two(); do_three()

Here is a sample comprehension to make the distinction:

>>> [i for i in xrange(10) if i == 9]
[9]

The ConnectTimeout option allows you to tell your ssh client how long you're willing to wait for a connection before returning an error. By setting ConnectTimeout to 1, you're effectively saying "try for at most 1 second and then fail if you haven't connected yet".

The problem is that when you connect by name, the DNS lookup can take several seconds. Connecting by IP address is much faster, and may actually work in one second or less. What sinelaw is experiencing is that every attempt to connect by DNS name is failing to occur within one second. The default setting of ConnectTimeout defers to the linux kernel connect timeout, which is usually pretty long.

I understand that std::atomic<> makes an object atomic.

That's a matter of perspective... you can't apply it to arbitrary objects and have their operations become atomic, but the provided specialisations for (most) integral types and pointers can be used.

a = a + 12;

std::atomic<> does not (use template expressions to) simplify this to a single atomic operation, instead the operator T() const volatile noexcept member does an atomic load() of a, then twelve is added, and operator=(T t) noexcept does a store(t).

UPDATE for .NET 5!

The below applies on/after NOV2020 when .NET 5 is officially out.

(see quick terminology section below, not just the How-to's)

How-To (CLI)

Pre-requisites

• Download latest version of the .net 5 SDK. Link

Steps

1. Open a terminal (e.g: bash, command prompt, powershell) and in the same directory as your .csproj file enter the below command:

dotnet publish --output "{any directory}" --runtime {runtime} --configuration {Debug|Release} -p:PublishSingleFile={true|false} -p:PublishTrimmed={true|false} --self-contained {true|false}

example:

dotnet publish --output "c:/temp/myapp" --runtime win-x64 --configuration Release -p:PublishSingleFile=true -p:PublishTrimmed=true --self-contained true

How-To (GUI)

Pre-requisites

• If reading pre NOV2020: Latest version of Visual Studio Preview*
• If reading NOV2020+: Latest version of Visual Studio*

*In above 2 cases, the latest .net5 SDK will be automatically installed on your PC.

Steps

1. Right-Click on Project, and click Publish
   

2. Click Start and choose Folder target, click next and choose Folder

3. Enter any folder location, and click Finish

4. Click on Edit
   

5. Choose a Target Runtime and tick on Produce Single File and save.*

6. Click Publish

7. Open a terminal in the location you published your app, and run the .exe. Example:

A little bit of terminology

Target Runtime
See the list of RID's

Deployment Mode

• Framework Dependent means a small .exe file produced but app assumed .Net 5 is installed on the host machine
• Self contained means a bigger .exe file because the .exe includes the framework but then you can run .exe on any machine, no need for .Net 5 to be pre-installed. NOTE: WHEN USING SELF CONTAINED, ADDITIONAL DEPENDENCIES (.dll's) WILL BE PRODUCED, NOT JUST THE .EXE

Enable ReadyToRun compilation
TLDR: it's .Net5's equivalent of Ahead of Time Compilation (AOT). Pre-compiled to native code, app would usually boot up faster. App more performant (or not!), depending on many factors. More info here

Trim unused assemblies
When set to true, dotnet will generate a very lean and small .exe and only include what it needs. Be careful here. Example: when using reflection in your app you probably don't want to set this flag to true.

Microsoft Doc

Previous Post

UPDATE (31-OCT-2019)

For anyone that wants to do this via a GUI and:

• Is using Visual Studio 2019
• Has .NET Core 3.0 installed (included in latest version of Visual Studio 2019)
• Wants to generate a single file

Note

Notice the large file size for such a small application

You can add the "PublishTrimmed" property. The application will only include components that are used by the application. Caution: don't do this if you are using reflection

Publish again

As Johannes says -- not enough rep to comment directly on his answer -- you can indeed do this as long as all elements' "dimensions are specified as a multiple of the font's size. Meaning, everything where you used %, em or ex units". Although I think % are based on containing element, not font-size.

And you wouldn't normally use these relative units for images, given they are composed of pixels, but there's a trick which makes this a lot more practical.

If you define body{font-size: 62.5%}; then 1em will be equivalent to 10px. As far as I know this works across all main browsers.

Then you can specify your (e.g.) 100px square images with width: 10em; height: 10em; and assuming Firefox's scaling is set to default, the images will be their natural size.

Make body{font-size: 125%}; and everything - including images - wil be double original size.

My recomendation is to keep the getRuntime().exec because exec uses the ProcessBuilder.

Try

 p=r.exec(new String[] {"winrar", "x", "h:\\myjar.jar", "*.*", "h:\\new"}, null, dir);

The new ASP.NET Web API is a continuation of the previous WCF Web API project (although some of the concepts have changed).

WCF was originally created to enable SOAP-based services. For simpler RESTful or RPCish services (think clients like jQuery) ASP.NET Web API should be good choice.

For us, WCF is used for SOAP and Web API for REST. I wish Web API supported SOAP too. We are not using advanced features of WCF. Here is comparison from MSDN:

ASP.net Web API is all about HTTP and REST based GET,POST,PUT,DELETE with well know ASP.net MVC style of programming and JSON returnable; web API is for all the light weight process and pure HTTP based components. For one to go ahead with WCF even for simple or simplest single web service it will bring all the extra baggage. For light weight simple service for ajax or dynamic calls always WebApi just solves the need. This neatly complements or helps in parallel to the ASP.net MVC.

Check out the podcast : Hanselminutes Podcast 264 - This is not your father's WCF - All about the WebAPI with Glenn Block by Scott Hanselman for more information.

In the scenarios listed below you should go for WCF:

1. If you need to send data on protocols like TCP, MSMQ or MIME
2. If the consuming client just knows how to consume SOAP messages

WEB API is a framework for developing RESTful/HTTP services.

There are so many clients that do not understand SOAP like Browsers, HTML5, in those cases WEB APIs are a good choice.

HTTP services header specifies how to secure service, how to cache the information, type of the message body and HTTP body can specify any type of content like HTML not just XML as SOAP services.

Recently I learned of the following syntax:

DELETE (SELECT *
        FROM productfilters pf
        INNER JOIN product pr
            ON pf.productid = pr.id
        WHERE pf.id >= 200
            AND pr.NAME = 'MARK')

I think it looks much cleaner then other proposed code.

There is a free nuget package (Pdf2Image), which allows the extraction of pdf pages to jpg files or to a collection of images (List ) in just one line

        string file = "c:\\tmp\\test.pdf";

        List<System.Drawing.Image> images = PdfSplitter.GetImages(file, PdfSplitter.Scale.High);

        PdfSplitter.WriteImages(file, "c:\\tmp", PdfSplitter.Scale.High, PdfSplitter.CompressionLevel.Medium);

All source is also available on github Pdf2Image

I had this issue recently. In my case, I had my IDE set to choose which compiler (C or C++) to use on each file according to its extension, and I was trying to call a C function (i.e. from a .c file) from C++ code.

The .h file for the C function wasn't wrapped in this sort of guard:

#ifdef __cplusplus
extern "C" {
#endif

// all of your legacy C code here

#ifdef __cplusplus
}
#endif

I could've added that, but I didn't want to modify it, so I just included it in my C++ file like so:

extern "C" {
#include "legacy_C_header.h"
}

(Hat tip to UncaAlby for his clear explanation of the effect of extern "C".)

If the required properties need to set in system then there is no option than -D But if you need those properties while bootstrapping an application then loading properties through the properties files is a best option. It will not require to change build for a single property.

MailAddress fromAddress = new MailAddress  (fromMail,fromName);
MailAddress toAddress = new MailAddress(toMail,toName);
MailMessage message = new MailMessage(fromAddress,toAddress);
message.Subject = subject;
message.Body = body;
SmtpClient smtp = new SmtpClient()
{
    Host = host, Port = port,
    enabHost = "smtp.gmail.com",
    Port = 25,
    EnableSsl = true,
    UseDefaultCredentials = true,
    Credentials = new  NetworkCredentials (fromMail, password)
};
smtp.send(message);

My code to convert array to Json

Code

List<String>a = new ArrayList<String>();
a.add("so 1");
a.add("so 2");
a.add("so 3");
JSONArray jray = new JSONArray(a);

System.out.println(jray.toString()); 

output

["so 1","so 2","so 3"]

You need a gutter between two div gutter can be made as following

margin(gutter) = width - gutter size E.g margin = calc(70% - 2em)

<body bgcolor="gray">
<section id="main">
        <div id="left">
            Something here     
        </div>
        <div id="right">
                Someone there
        </div>
</section>
</body>
<style>
body{
    font-size: 10px;
}

#main div{
    float: left;
    background-color:#ffffff;
    width: calc(50% - 1.5em);
    margin-left: 1.5em;
}
</style>

You have no combinator (space, >, +...) so no children will get involved, ever.

However, you could avoid the need for jQuery by using an ID and getElementById, or you could use the old getElementsByName("frmSave")[0] or the even older document.forms['frmSave']. jQuery is unnecessary here.

This question has been posted long time ago, but I found an alternative way to answer it. So I decided to share it here.
Firstly, one must know that: if two vectors are perpendicular, their dot product equals zero.
The normal vector (x',y') is perpendicular to the line connecting (x1,y1) and (x2,y2). This line has direction (x2-x1,y2-y1), or (dx,dy).
So,

(x',y').(dx,dy) = 0
x'.dx + y'.dy = 0

The are plenty of pairs (x',y') that satisfy the above equation. But the best pair that ALWAYS satisfies is either (dy,-dx) or (-dy,dx)

list1 = (x[0] for x in source_list)
list2 = (x[1] for x in source_list)

You're trying to call the isEmpty() method on a null reference (as List test = null; ). This will surely throw a NullPointerException. You should do if(test!=null) instead (Checking for null first).

The method isEmpty() returns true, if an ArrayList object contains no elements; false otherwise (for that the List must first be instantiated that is in your case is null).

Edit:

You may want to see this question.

I wouldn't recommended this is you've got a lot of "thinking" in your app, but using XSLT could be better (and potentially faster with XSLT-to-bytecode compilation) than Java manipulation.

I had a similar problem and ended up using parse_url and parse_str, which as long as the URL in the parameter is correctly url encoded (which it definitely should) allows you to access both all the parameters of the actual URL, as well as the parameters of the encoded URL in the query parameter, like so:

$get_url = "http://google.com/?var=234&key=234";
$my_url = "http://localhost/test.php?id=" . urlencode($get_url);

function so_5645412_url_params($url) {
    $url_comps = parse_url($url);
    $query = $url_comps['query'];

    $args = array();
    parse_str($query, $args);

    return $args;
}

$my_url_args = so_5645412_url_params($my_url); // Array ( [id] => http://google.com/?var=234&key=234 )
$get_url_args = so_5645412_url_params($my_url_args['id']); // Array ( [var] => 234, [key] => 234 )

1. Add an exit handler that closes all the bars.
2. __del__() gets called when the number of references to an object hits 0 while the VM is still running. This may be caused by the GC.
3. If __init__() raises an exception then the object is assumed to be incomplete and __del__() won't be invoked.

This typically is caused by the mount directory being left mounted due to a crash of your filesystem. Go to the parent directory of the mount point and enter fusermount -u YOUR_MNT_DIR.

If this doesn't do the trick, do sudo umount -l YOUR_MNT_DIR.

I had the same problem and the solution was to encapsulate the json inside this function

jsonp(

.... your json ...

)

I fixed this problem by changing the first line in Application.mk from

APP_STL := gnustl_static

to

APP_STL := c++_static

For a single result:

if (reader.Read())
{
    Response.Write(reader[0].ToString());
    Response.Write(reader[1].ToString());
}

For multiple results:

while (reader.Read())
{
    Response.Write(reader[0].ToString());
    Response.Write(reader[1].ToString());
}

The proper way is to use Hibernate Transformers:

public class StudentDTO {
private String studentName;
private String courseDescription;

public StudentDTO() { }  
...
} 

.

List resultWithAliasedBean = s.createSQLQuery(
"SELECT st.name as studentName, co.description as courseDescription " +
"FROM Enrolment e " +
"INNER JOIN Student st on e.studentId=st.studentId " +
"INNER JOIN Course co on e.courseCode=co.courseCode")
.setResultTransformer( Transformers.aliasToBean(StudentDTO.class))
.list();

StudentDTO dto =(StudentDTO) resultWithAliasedBean.get(0);

Iterating througth Object[] is redundant and would have some performance penalty. Detailed information about transofrmers usage you will find here: Transformers for HQL and SQL

If you are looking for even more simple solution you can use out-of-the-box-map-transformer:

List iter = s.createQuery(
"select e.student.name as studentName," +
"       e.course.description as courseDescription" +
"from   Enrolment as e")
.setResultTransformer( Transformers.ALIAS_TO_ENTITY_MAP )
.iterate();

String name = (Map)(iter.next()).get("studentName");

In 2013, you should use something like Silex or Slim

Silex example:

require_once __DIR__.'/../vendor/autoload.php'; 

$app = new Silex\Application(); 

$app->get('/hello/{name}', function($name) use($app) { 
    return 'Hello '.$app->escape($name); 
}); 

$app->run(); 

Slim example:

$app = new \Slim\Slim();
$app->get('/hello/:name', function ($name) {
    echo "Hello, $name";
});
$app->run();

See this implementation from PEP318, implementing the singleton pattern with a decorator:

def singleton(cls):
    instances = {}
    def getinstance():
        if cls not in instances:
            instances[cls] = cls()
        return instances[cls]
    return getinstance

@singleton
class MyClass:
    ...

1. System.exit() is a method that causes JVM to exit.
2. return just returns the control to calling function.
3. return 8 will return control and value 8 to calling method.

Here is another way...

The HTML:

<table>
<tbody>
       <tr class='clickableRow'>
       <td>Blah Blah</td>
       <td>1234567</td>
       <td>£158,000</td>
        </tr>
</tbody>
</table>

The jQuery:

$(function() {
      $(".clickableRow").on("click", function() {
          location.href="http://google.com";

      });

});

# Write a Python program that accepts a string and calculate the number of digits 
# andletters.

    stre =input("enter the string-->")
    countl = 0
    countn = 0
    counto = 0
    for i in stre:
        if i.isalpha():
            countl += 1
        elif i.isdigit():
            countn += 1
        else:
            counto += 1
    print("The number of letters are --", countl)
    print("The number of numbers are --", countn)
    print("The number of characters are --", counto)

If you try exec sp_rename and receieve a LockMatchID error then it might help to add a use [database] statement first:

I tried

 exec sp_rename '[database_name].[dbo].[table_name]', 'new_table_name';
 -- Invalid EXECUTE statement using object "Object", method "LockMatchID".

What I had to do to fix it was to rewrite it to:

use database_name
exec sp_rename '[dbo].[table_name]', 'new_table_name';

I honestly thought that the casting method would work fine. Since it doesn't you can try stringstream. An example is below:

#include <sstream>
#include <string>
std::stringstream ss;
std::string target;
char mychar = 'a';
ss << mychar;
ss >> target;

use array detect method if you wanted to return first value where block returns true

[1,2,3,11,34].detect(&:even?) #=> 2

OR

[1,2,3,11,34].detect{|i| i.even?} #=> 2

If you wanted to return all values where block returns true then use select

[1,2,3,11,34].select(&:even?)  #=> [2, 34]

To enforce non-www and https in a single request, you can use the following Rule in your htaccess :

RewriteEngine on

RewriteCond %{HTTP_HOST} ^www\. [OR]
RewriteCond %{HTTPS} off
RewriteCond %{HTTP_HOST} ^(?:www\.)?(.+)$
RewriteRule ^ https://%1%{REQUEST_URI} [NE,L,R]

This redirects http://www.example.com/ or https://www.example.com/ to ssl non-www https://example.com/ .

I am using R Temp Redirect flag for testing purpose and to avoid browser caching. If you want to make the redirect permanent , just change the R flag to R=301 .

SetForegroundWindow( /* window to gain focus */ );
SendKeys.SendWait("^{ESC}"); // ^{ESC} is code for ctrl + esc which mimics the windows key.

These commands will help in overwriting code of demo branch into master

git fetch --all

Pull Your demo branch on local

git pull origin demo

Now checkout to master branch. This branch will be completely changed with the code on demo branch

git checkout master

Stay in the master branch and run this command.

git reset --hard origin/demo

reset means you will be resetting current branch

--hard is a flag that means it will be reset without raising any merge conflict

origin/demo will be the branch that will be considered to be the code that will forcefully overwrite current master branch

The output of the above command will show you your last commit message on origin/demo or demo branch

Then, in the end, force push the code on the master branch to your remote repo.

git push --force

So, we have a situation when we need to statically get class object or a class full/simple name without an explicit usage of MyClass.class syntax.

It can be really handy in some cases, e.g. logger instance for the kotlin upper-level functions (in this case kotlin creates a static Java class not accessible from the kotlin code).

We have a few different variants for getting this info:

1. new Object(){}.getClass().getEnclosingClass();
   noted by Tom Hawtin - tackline

2. getClassContext()[0].getName(); from the SecurityManager
   noted by Christoffer

3. new Throwable().getStackTrace()[0].getClassName();
   by count ludwig

4. Thread.currentThread().getStackTrace()[1].getClassName();
   from Keksi

5. and finally awesome
   MethodHandles.lookup().lookupClass();
   from Rein

I've prepared a jmh benchmark for all variants and results are:

# Run complete. Total time: 00:04:18

StaticClassLookup.Throwable_stackTrace_0_className             avgt   30  10221.209 ± 176.847  ns/op

Conclusions

1. Best variant to use, rather clean and monstrously fast.
   Available only since Java 7 and Android API 26!

 MethodHandles.lookup().lookupClass();

2. In case you need this functionality for Android or Java 6, you can use the second best variant. It's rather fast too, but creates an anonymous class in each place of usage :(

 new Object(){}.getClass().getEnclosingClass();

3. If you need it in many places and don't want your bytecode to bloat due to tons of anonymous classes – SecurityManager is your friend (third best option).

   But you can't just call getClassContext() – it's protected in the SecurityManager class. You will need some helper class like this:

 // Helper class
 public final class CallerClassGetter extends SecurityManager
 {
    private static final CallerClassGetter INSTANCE = new CallerClassGetter();
    private CallerClassGetter() {}

    public static Class<?> getCallerClass() {
        return INSTANCE.getClassContext()[1];
    }
 }

 // Usage example:
 class FooBar
 {
    static final Logger LOGGER = LoggerFactory.getLogger(CallerClassGetter.getCallerClass())
 }

4. You probably don't ever need to use last two variants based on the getStackTrace() from exception or the Thread.currentThread(). Very inefficient and can return only the class name as a String, not the Class<*> instance.

P.S.

If you want to create a logger instance for static kotlin utils (like me :), you can use this helper:

import org.slf4j.Logger
import org.slf4j.LoggerFactory

// Should be inlined to get an actual class instead of the one where this helper declared
// Will work only since Java 7 and Android API 26!
@Suppress("NOTHING_TO_INLINE")
inline fun loggerFactoryStatic(): Logger
    = LoggerFactory.getLogger(MethodHandles.lookup().lookupClass())

Usage example:

private val LOGGER = loggerFactoryStatic()

/**
 * Returns a pseudo-random, uniformly distributed value between the
 * given least value (inclusive) and bound (exclusive).
 *
 * @param min the least value returned
 * @param max the upper bound (exclusive)
 *
 * @return the next value
 * @throws IllegalArgumentException if least greater than or equal to bound
 * @see java.util.concurrent.ThreadLocalRandom.nextDouble(double, double)
 */
fun Random.nextDouble(min: Double = .0, max: Double = 1.0): Double {
    if (min >= max) {
        if (min == max) return max
        LOGGER.warn("nextDouble: min $min > max $max")
        return min
    }
    return nextDouble() * (max - min) + min
}

The height of the bottom Navigation bar is 48dp (in both portrait and landscape mode) and is 42dp when the bar is placed vertically.

Enum singleton

The simplest way to implement a Singleton that is thread-safe is using an Enum

public enum SingletonEnum {
  INSTANCE;
  public void doSomething(){
    System.out.println("This is a singleton");
  }
}

This code works since the introduction of Enum in Java 1.5

Double checked locking

If you want to code a “classic” singleton that works in a multithreaded environment (starting from Java 1.5) you should use this one.

public class Singleton {

  private static volatile Singleton instance = null;

  private Singleton() {
  }

  public static Singleton getInstance() {
    if (instance == null) {
      synchronized (Singleton.class){
        if (instance == null) {
          instance = new Singleton();
        }
      }
    }
    return instance ;
  }
}

This is not thread-safe before 1.5 because the implementation of the volatile keyword was different.

Early loading Singleton (works even before Java 1.5)

This implementation instantiates the singleton when the class is loaded and provides thread safety.

public class Singleton {

  private static final Singleton instance = new Singleton();

  private Singleton() {
  }

  public static Singleton getInstance() {
    return instance;
  }

  public void doSomething(){
    System.out.println("This is a singleton");
  }

}

It's still valid to use IE=edge,chrome=1.

But, since the chrome frame project has been wound down the chrome=1 part is redundant for browsers that don't already have the chrome frame plug in installed.

I use the following for correctness nowadays

<meta http-equiv="X-UA-Compatible" content="IE=edge" />

I had the same problem but solved it when I realized that I didn't compile it with the correct casing. You may have been doing

javac Weatherarray.java

when it should have been

javac WeatherArray.java

joaquin's answer works, but has the side effect of removing ticks from the left side of the axes. To fix this, follow up tick_right() with a call to set_ticks_position('both'). A revised example:

from matplotlib import pyplot as plt

f = plt.figure()
ax = f.add_subplot(111)
ax.yaxis.tick_right()
ax.yaxis.set_ticks_position('both')
plt.plot([2,3,4,5])
plt.show()

The result is a plot with ticks on both sides, but tick labels on the right.

I also had an issue with multiline strings in this scenario. @Iman's backtick(`) solution worked great in the modern browsers but caused an invalid character error in Internet Explorer. I had to use the following:

'@item.MultiLineString.Replace(Environment.NewLine, "<br />")'

Then I had to put the carriage returns back again in the js function. Had to use RegEx to handle multiple carriage returns.

// This will work for the following:
// "hello\nworld"
// "hello<br>world"
// "hello<br />world"
$("#MyTextArea").val(multiLineString.replace(/\n|<br\s*\/?>/gi, "\r"));

Throw an exception.

if ( fileName.IndexOfAny(Path.GetInvalidFileNameChars()) > -1 )
            {
                throw new ArgumentException();
            }

You need seek to the beginning of the file before writing and then use file.truncate() if you want to do inplace replace:

import re

myfile = "path/test.xml"

with open(myfile, "r+") as f:
    data = f.read()
    f.seek(0)
    f.write(re.sub(r"<string>ABC</string>(\s+)<string>(.*)</string>", r"<xyz>ABC</xyz>\1<xyz>\2</xyz>", data))
    f.truncate()

The other way is to read the file then open it again with open(myfile, 'w'):

with open(myfile, "r") as f:
    data = f.read()

with open(myfile, "w") as f:
    f.write(re.sub(r"<string>ABC</string>(\s+)<string>(.*)</string>", r"<xyz>ABC</xyz>\1<xyz>\2</xyz>", data))

Neither truncate nor open(..., 'w') will change the inode number of the file (I tested twice, once with Ubuntu 12.04 NFS and once with ext4).

By the way, this is not really related to Python. The interpreter calls the corresponding low level API. The method truncate() works the same in the C programming language: See http://man7.org/linux/man-pages/man2/truncate.2.html

Check out the MSDN page for SortedList:

From Remarks section:

The SortedList<(Of <(TKey, TValue>)>) generic class is a binary search tree with O(log n) retrieval, where n is the number of elements in the dictionary. In this, it is similar to the SortedDictionary<(Of <(TKey, TValue>)>) generic class. The two classes have similar object models, and both have O(log n) retrieval. Where the two classes differ is in memory use and speed of insertion and removal:

• SortedList<(Of <(TKey, TValue>)>) uses less memory than SortedDictionary<(Of <(TKey, TValue>)>).

• SortedDictionary<(Of <(TKey, TValue>)>) has faster insertion and removal operations for unsorted data, O(log n) as opposed to O(n) for SortedList<(Of <(TKey, TValue>)>).

• If the list is populated all at once from sorted data, SortedList<(Of <(TKey, TValue>)>) is faster than SortedDictionary<(Of <(TKey, TValue>)>).

Or try adding this...

$code = @"
[DllImport("kernel32.dll")]
public static extern int GetExitCodeProcess(IntPtr hProcess, out Int32 exitcode);
"@
$type = Add-Type -MemberDefinition $code -Name "Win32" -Namespace Win32 -PassThru
[Int32]$exitCode = 0
$type::GetExitCodeProcess($process.Handle, [ref]$exitCode)

By using this code, you can still let PowerShell take care of managing redirected output/error streams, which you cannot do using System.Diagnostics.Process.Start() directly.

According to the MSDN documentation here, The basename argument specifies "The root name of the resource file without its extension but including any fully qualified namespace name.

I'm afraid your posted example is not working, since X and Y aren't defined. So instead of pcolormesh let's use imshow:

import numpy as np
import matplotlib.pyplot as plt

H = np.array([[1, 2, 3, 4],
              [5, 6, 7, 8],
              [9, 10, 11, 12],
              [13, 14, 15, 16]])  # added some commas and array creation code

fig = plt.figure(figsize=(6, 3.2))

ax = fig.add_subplot(111)
ax.set_title('colorMap')
plt.imshow(H)
ax.set_aspect('equal')

cax = fig.add_axes([0.12, 0.1, 0.78, 0.8])
cax.get_xaxis().set_visible(False)
cax.get_yaxis().set_visible(False)
cax.patch.set_alpha(0)
cax.set_frame_on(False)
plt.colorbar(orientation='vertical')
plt.show()

Actually just adding margin-bottom: -20px; to the tag class fixed it right up.

http://jsfiddle.net/dChUR/7/

Being block elements, div's naturally have defined borders that they try not to violate. To get them to layer for images, which have no content beside the image because they have no closing tag, you just have to force them to do what they do not want to do, like violate their natural boundaries.

.container {
  border: 1px solid #DDDDDD;
  width: 200px;
  height: 200px;
  }
.tag {
  float: left;
  position: relative;
  left: 0px;
  top: 0px;
  background-color: green;
  z-index: 1000;
  margin-bottom: -20px;
  }

Another toue to take would be to create div's using an image as the background, and then place content where ever you like.

<div id="imgContainer" style="
         background-image: url("foo.jpg"); 
         background-repeat: no-repeat; 
         background-size: cover; 
         -webkit-background-size: cover; 
         -mox-background-size: cover; 
         -o-background-size: cover;">
  <div id="theTag">BLAH BLAH BLAH</div>
</div>

I tried many solutions for this, and this is the one that worked for me :

1.commit/save container to new image :

1. ++ commit the container:
   # docker stop
   # docker commit CONTAINER_NAME
   # docker save --output IMAGE_NAME.tar IMAGE_NAME:TAG
   
   

ps:"Our container CONTAINER_NAME has a mounted volume at '/var/home'" ( you have to inspect your container to specify its volume path : # docker inspect CONTAINER_NAME )

2. ++ save its volume : we will use an ubuntu image to do the thing.
   # mkdir backup
   # docker run --rm --volumes-from CONTAINER_NAME -v ${pwd}/backup:/backup ubuntu bash -c “cd /var/home && tar cvf /backup/volume_backup.tar .”
   
   

Now when you look at ${pwd}/backup , you will find our volume under tar format.
Until now, we have our conatainer's image 'IMAGE_NAME.tar' and its volume 'volume_backup.tar'.

Now you can , recreate the same old container on a new host.

If there are multiple levels of inheritance, you can specify the direct base class, even if the actual implementation is at a lower level.

class Foo
{
public:
  virtual void DoStuff ()
  {
  }
};

class Bar : public Foo
{
};

class Baz : public Bar
{
public:
  void DoStuff ()
  {
    Bar::DoStuff() ;
  }
};

In this example, the class Baz specifies Bar::DoStuff() although the class Bar does not contain an implementation of DoStuff. That is a detail, which Baz does not need to know.

It is clearly a better practice to call Bar::DoStuff than Foo::DoStuff, in case a later version of Bar also overrides this method.

You can minimize the command prompt on during the run but you'll need two additional scripts: windowMode and getCmdPid.bat:

@echo off

call getCmdPid
call windowMode -pid %errorlevel% -mode minimized

call C:\Ruby192\bin\setrbvars.bat

Use the simplest one to check for future date

if(moment().diff(yourDate) >=  0)
     alert ("Past or current date");
else
     alert("It is a future date");

The isdigit method of the str type returns True iff the given string is nothing but one or more digits. If it's not, you know the string should be treated as just a string.

Looking at the jQuery code, this is what happens:

hide: function( speed, easing, callback ) {
    if ( speed || speed === 0 ) {
        return this.animate( genFx("hide", 3), speed, easing, callback);

    } else {
        for ( var i = 0, j = this.length; i < j; i++ ) {
            var display = jQuery.css( this[i], "display" );

            if ( display !== "none" ) {
                jQuery.data( this[i], "olddisplay", display );
            }
        }

        // Set the display of the elements in a second loop
        // to avoid the constant reflow
        for ( i = 0; i < j; i++ ) {
            this[i].style.display = "none";
        }

        return this;
    }
},

In all these scenarios outerScopeVar is modified or assigned a value asynchronously or happening in a later time(waiting or listening for some event to occur),for which the current execution will not wait.So all these cases current execution flow results in outerScopeVar = undefined

Let's discuss each examples(I marked the portion which is called asynchronously or delayed for some events to occur):

1.

Here we register an eventlistner which will be executed upon that particular event.Here loading of image.Then the current execution continuous with next lines img.src = 'lolcat.png'; and alert(outerScopeVar); meanwhile the event may not occur. i.e, funtion img.onload wait for the referred image to load, asynchrously. This will happen all the folowing example- the event may differ.

2.

Here the timeout event plays the role, which will invoke the handler after the specified time. Here it is 0, but still it registers an asynchronous event it will be added to the last position of the Event Queue for execution, which makes the guaranteed delay.

3.

This time ajax callback.

Node can be consider as a king of asynchronous coding.Here the marked function is registered as a callback handler which will be executed after reading the specified file.

5.

Obvious promise (something will be done in future) is asynchronous. see What are the differences between Deferred, Promise and Future in JavaScript?

Python 2.x:

print '-' * 3

Python 3.x:

print('-' * 3)

Here's a reasonably terse way to do it using a Prototype:

Date.prototype.getFormattedTime = function () {
    var hours = this.getHours() == 0 ? "12" : this.getHours() > 12 ? this.getHours() - 12 : this.getHours();
    var minutes = (this.getMinutes() < 10 ? "0" : "") + this.getMinutes();
    var ampm = this.getHours() < 12 ? "AM" : "PM";
    var formattedTime = hours + ":" + minutes + " " + ampm;
    return formattedTime;
}

Then all you have to do is convert your string value to a date and use the new method:

var stringValue = "February 04, 2011 19:00:00;
var dateValue = new Date(stringValue);
var formattedTime = dateValue.getFormattedTime();

Or in a single line:

var formattedTime = new Date("February 04, 2011 19:00:00").getFormattedTime();

This should help clear up any questions you may have: C# literals

Here is a table from the linked content:

Regular literal	Verbatim literal	Resulting string
"Hello"	@"Hello"	Hello
"Backslash: \\"	@"Backslash: \"	Backslash: \
"Quote: \""	@"Quote: """	Quote: "
"CRLF:\r\nPost CRLF"	@"CRLF: Post CRLF"	CRLF: Post CRLF

One more little thing, the theme solution does work if you inherit a base theme, so for app compact your theme should be:

<style name="AppTheme.Custom" parent="@style/Theme.AppCompat">
    <item name="colorAccent">@color/custom</item>
</style>

And then set this in the progress bar theme

<ProgressBar
    android:id="@+id/progressCircle_progressBar"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center_horizontal"
    android:theme="@style/AppTheme.Custom"
    android:indeterminate="true"/>

We've had similar problem and it was not enough to only remove commit and force push to GitLab.
It was still available in GitLab interface using url:

https://gitlab.example.com/<group>/<project>/commit/<commit hash>

We've had to remove project from GitLab and recreate it to get rid of this commit in GitLab UI.

What you need is to map your array of objects and remember that every item will be an object, so that you will use for instance dot notation to take the values of the object.

In your component

 [
    {
        name: 'Sam',
        email: '[email protected]'
    },

    {
        name: 'Ash',
        email: '[email protected]'
    }
].map((anObjectMapped, index) => {
    return (
        <p key={`${anObjectMapped.name}_{anObjectMapped.email}`}>
            {anObjectMapped.name} - {anObjectMapped.email}
        </p>
    );
})

And remember when you put an array of jsx it has a different meaning and you can not just put object in your render method as you can put an array.

Take a look at my answer at mapping an array to jsx

vim +21490go script.py

From the command line will open the file and take you to position 21490 in the buffer.

Triggering it from the command line like this allows you to automate a script to parse the exception message and open the file to the problem position.

Excerpt from man vim:

+{command}

-c {command}

{command} will be executed after the first file has been read. {command} is interpreted as an Ex command. If the {command} contains spaces it must be enclosed in double quotes (this depends on the shell that is used).

I use this one:

document.title = "your_customize_title";

I'm using this since the begin and it always work. =)

System.setProperty("webdriver.chrome.driver", "C:\\pathto\\my\\chromedriver.exe");
WebDriver driver = new ChromeDriver();
driver.get("http://www.google.com");

check the following code to call one activity from another.

Intent intent = new Intent(CurrentActivity.this, OtherActivity.class);
CurrentActivity.this.startActivity(intent);

In Linux Mint, and most likely Ubuntu, you can try "nvidia-smi --loop=1"

I had the same problem. This work fine for me:

str(objdata).encode('utf-8')

I also see that the page loading (performance) takes a long time on using h:commandLink than h:link. h:link is faster compared to h:commandLink

Try this .{3,} this will match any characher except new line (\n)

First off, I use nvm on linux machine.

When looking at the documentation for nvm at https://www.npmjs.org/package/nvm, it recommendations that you install nvm globally using the -g switch.

npm install -g nvm

Also there is a . in the path variable that they recommend.

export PATH=./node_modules/.bin:$PATH

so maybe your path should be

C:\Program Files (x86)\nodejs\node_modules\npm\\.bin

You need to set option CURLOPT_PROXYTYPE to CURLPROXY_SOCKS5_HOSTNAME, which sadly wasn't defined in old PHP versions, circa pre-5.6; if you have earlier in but you can explicitly use its value, which is equal to 7:

curl_setopt($ch, CURLOPT_PROXYTYPE, 7);

Perhaps not what the OP was after, but for those searching the URL to simply access a readable object on S3 is more like:

https://<region>.amazonaws.com/<bucket-name>/<key>

Where <region> is something like s3-ap-southeast-2.

Click on the item in the S3 GUI to get the link for your bucket.

Although this may not be the cause of your issue, you'll get the same error if there are two MySQL services running on the same port. You can check on windows by looking at the list of services in the services tab of Task Manager.

Update in 2017: Hey. This is a terrible answer. Don't use it. Back in the old days this type of jQuery use was common. And it probably worked back then. Just read it, realize it's terrible, then move on (or downvote or, whatever) to one of the other answers that are better for today's jQuery.

$("input[type=radio]").change(function(){
    alert( $("input[type=radio][name="+ this.name + "]").val() );
});

You can use the update() method to build a new dictionary containing all the items:

dall = {}
dall.update(d1)
dall.update(d2)
dall.update(d3)

Or, in a loop:

dall = {}
for d in [d1, d2, d3]:
  dall.update(d)

In summary :

<input type="submit">

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

Both by default will visually draw a button that performs the same action (submit the form).

However, it is recommended to use <button type="submit"> because it has better semantics, better ARIA support and it is easier to style.

Simpler solution:

var dt = $('#table_scroll').dataTable();

$.getJSON(url, null, function (json) {
    dt.fnClearTable();
    dt.fnAddData(json.aaData);
    dt.fnDraw();
});

The best solution in my opinion is to encapsulate the InputStream in a JSONTokener object. Something like this:

JSONObject jsonObject = new JSONObject(new JSONTokener(inputStream));

Other cases

io.of('/chat').on('connection', function (socket) {
    //sending to all clients in 'room' and you
    io.of('/chat').in('room').emit('message', "data");
};

You would need to do something like this. I am typing this off the top of my head, so this may not be 100% correct.

CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB(); CGContextRef context = CGBitmapContextCreate(NULL, 640, 360, 8, 4 * width, colorSpace, kCGImageAlphaPremultipliedFirst); CGColorSpaceRelease(colorSpace);  CGContextDrawImage(context, CGRectMake(0,-160,640,360), cgImgFromAVCaptureSession);  CGImageRef image = CGBitmapContextCreateImage(context); UIImage* myCroppedImg = [UIImage imageWithCGImage:image]; CGContextRelease(context);       

You are populating your dictionaries with references to a single list so when you update it, the update is reflected across all the references. Try a dictionary comprehension instead. See Create a dictionary with list comprehension in Python

d = {k : v for k in blah blah blah}

Here is my approach by creating a wrapper to run tests from the command line:

#!/usr/bin/env python3
import os, sys, unittest, argparse, inspect, logging

if __name__ == '__main__':
    # Parse arguments.
    parser = argparse.ArgumentParser(add_help=False)
    parser.add_argument("-?", "--help",     action="help",                        help="show this help message and exit" )
    parser.add_argument("-v", "--verbose",  action="store_true", dest="verbose",  help="increase output verbosity" )
    parser.add_argument("-d", "--debug",    action="store_true", dest="debug",    help="show debug messages" )
    parser.add_argument("-h", "--host",     action="store",      dest="host",     help="Destination host" )
    parser.add_argument("-b", "--browser",  action="store",      dest="browser",  help="Browser driver.", choices=["Firefox", "Chrome", "IE", "Opera", "PhantomJS"] )
    parser.add_argument("-r", "--reports-dir", action="store",   dest="dir",      help="Directory to save screenshots.", default="reports")
    parser.add_argument('files', nargs='*')
    args = parser.parse_args()

    # Load files from the arguments.
    for filename in args.files:
        exec(open(filename).read())

    # See: http://codereview.stackexchange.com/q/88655/15346
    def make_suite(tc_class):
        testloader = unittest.TestLoader()
        testnames = testloader.getTestCaseNames(tc_class)
        suite = unittest.TestSuite()
        for name in testnames:
            suite.addTest(tc_class(name, cargs=args))
        return suite

    # Add all tests.
    alltests = unittest.TestSuite()
    for name, obj in inspect.getmembers(sys.modules[__name__]):
        if inspect.isclass(obj) and name.startswith("FooTest"):
            alltests.addTest(make_suite(obj))

    # Set-up logger
    verbose = bool(os.environ.get('VERBOSE', args.verbose))
    debug   = bool(os.environ.get('DEBUG', args.debug))
    if verbose or debug:
        logging.basicConfig( stream=sys.stdout )
        root = logging.getLogger()
        root.setLevel(logging.INFO if verbose else logging.DEBUG)
        ch = logging.StreamHandler(sys.stdout)
        ch.setLevel(logging.INFO if verbose else logging.DEBUG)
        ch.setFormatter(logging.Formatter('%(asctime)s %(levelname)s: %(name)s: %(message)s'))
        root.addHandler(ch)
    else:
        logging.basicConfig(stream=sys.stderr)

    # Run tests.
    result = unittest.TextTestRunner(verbosity=2).run(alltests)
    sys.exit(not result.wasSuccessful())

For sake of simplicity, please excuse my non-PEP8 coding standards.

Then you can create BaseTest class for common components for all your tests, so each of your test would simply look like:

from BaseTest import BaseTest
class FooTestPagesBasic(BaseTest):
    def test_foo(self):
        driver = self.driver
        driver.get(self.base_url + "/")

To run, you simply specifying tests as part of the command line arguments, e.g.:

./run_tests.py -h http://example.com/ tests/**/*.py

For me the cause of the issue was that the format of username was incorrect. It was earlierly specified as "mydomain\user". I removed the domain part and the error was gone.

PS I was using ServerBind authentication.

I just discovered that adding a directory of swift files to a project won't work. You need to create a group first for the directory, then add the swift files...

Faced to this issue after a long time since question asked here. when checking material-ui code I found it's now accessible through inputRef property.

...
<CssTextField
  inputRef={(c) => {this.myRefs.username = c}}
  label="Username"
  placeholder="xxxxxxx"
  margin="normal"
  className={classes.textField}
  variant="outlined"
  fullWidth
/>
...

Then Access value like this.

  onSaveUser = () => {
    console.log('Saving user');
    console.log(this.myRefs.username.value);
  }

I'm not aware of any way to programmatically create these URLs, but the existing username space (www.facebook.com/something) works on fb.me also (e.g. http://fb.me/facebook )

Just make a new Date object with the stamp's getTime() value as a parameter.

Here's an example (I use an example timestamp of the current time):

Timestamp stamp = new Timestamp(System.currentTimeMillis());
Date date = new Date(stamp.getTime());
System.out.println(date);

In order to uninstall miniconda, simply remove the miniconda folder,

rm -r ~/miniconda/

As for avoiding conflicts between different Python environments, you can use virtual environments. In particular, with Miniconda, the following workflow could be used,

$ wget https://repo.continuum.io/miniconda/Miniconda3-3.7.0-Linux-x86_64.sh -O ~/miniconda.sh
$ bash miniconda
$ conda env remove --yes -n new_env    # remove the environement new_env if it exists (optional)
$ conda create --yes -n new_env pip numpy pandas scipy matplotlib scikit-learn nltk ipython-notebook seaborn python=2
$ activate new_env
$ # pip install modules if needed, run python scripts, etc
  # everything will be installed in the new_env
  # located in ~/miniconda/envs/new_env
$ deactivate

The example below seemed to work. Just setting a height on the first element

<ul class="row">
    <li class="span4" style="height: 100px"><h1>1</h1></li>
    <li class="span4"><h1>2</h1></li>
    <li class="span4"><h1>3</h1></li>
    <li class="span4"><h1>4</h1></li>
    <li class="span4"><h1>5</h1></li>
    <li class="span4"><h1>6</h1></li>
    <li class="span4"><h1>7</h1></li>
    <li class="span4"><h1>8</h1></li>
</ul>

I can't help but thinking it's the wrong use of a row though.

backdrop-filter

Unfortunately Mozilla has really dropped the ball and taken it's time with the feature. I'm personally hoping it makes it in to the next Firefox ESR as that is what the next major version of Waterfox will use.

MDN (Mozilla Developer Network) article: https://developer.mozilla.org/en-US/docs/Web/CSS/backdrop-filter

Mozilla implementation: https://bugzilla.mozilla.org/show_bug.cgi?id=1178765

From the MDN documentation page:

/* <filter-function> values */
backdrop-filter: blur(2px);
backdrop-filter: brightness(60%);

The following steps are to reset the password for a user in case you forgot, this would also solve your mentioned error.

First, stop your MySQL:

sudo /etc/init.d/mysql stop

Now start up MySQL in safe mode and skip the privileges table:

sudo mysqld_safe --skip-grant-tables &

Login with root:

mysql -uroot

And assign the DB that needs to be used:

use mysql;

Now all you have to do is reset your root password of the MySQL user and restart the MySQL service:

update user set password=PASSWORD("YOURPASSWORDHERE") where User='root';

flush privileges;

quit and restart MySQL:

quit

sudo /etc/init.d/mysql stop sudo /etc/init.d/mysql start Now your root password should be working with the one you just set, check it with:

mysql -u root -p

Properly parenthesized for clarity, it is

hsb.s = (max != 0) ? (255 * delta / max) : 0;

meaning return either

• 255*delta/max if max != 0
• 0 if max == 0

You should use the EndXXX of your async method to return the value. EndXXX should wait until there is a result using the IAsyncResult's WaitHandle and than return with the value.

If the data is stored as INT, you may want to try

Average = (R1 + R2 + R3 + R4 + R5) / 5.0

whenever you deal with spaces in filenames, use quotes

net use "m:\Server01\my folder" /USER:mynetwork\Administrator "Mypassword" /persistent:yes

npm install now supports this

npm install --save ../path/to/mymodule

For this to work mymodule must be configured as a module with its own package.json. See Creating NodeJS modules.

As of npm 2.0, local dependencies are supported natively. See danilopopeye's answer to a similar question. I've copied his response here as this question ranks very high in web search results.

This feature was implemented in the version 2.0.0 of npm. For example:

{
  "name": "baz",
  "dependencies": {
    "bar": "file:../foo/bar"
  }
}

Any of the following paths are also valid:

../foo/bar
~/foo/bar
./foo/bar
/foo/bar

syncing updates

Since npm install copies mymodule into node_modules, changes in mymodule's source will not automatically be seen by the dependent project.

There are two ways to update the dependent project with

• Update the version of mymodule and then use npm update: As you can see above, the package.json "dependencies" entry does not include a version specifier as you would see for normal dependencies. Instead, for local dependencies, npm update just tries to make sure the latest version is installed, as determined by mymodule's package.json. See chriskelly's answer to this specific problem.

• Reinstall using npm install. This will install whatever is at mymodule's source path, even if it is older, or has an alternate branch checked out, whatever.

myTest.js

module.exports.get = function () {};

exports.put = function () {};

console.log(module.exports)
// output: { get: [Function], put: [Function] }

exports and module.exports are the same and a reference to the same object. You can add properties by both ways as per your convenience.

That's a bad practice to use the == equality operator instead of ===.

undefined === undefined // true
null == undefined // true
null === undefined // false

The object.x === undefined should return true if x is unknown property.

In chapter Bad Parts of JavaScript: The Good Parts, Crockford writes the following:

If you attempt to extract a value from an object, and if the object does not have a member with that name, it returns the undefined value instead.

In addition to undefined, JavaScript has a similar value called null. They are so similar that == thinks they are equal. That confuses some programmers into thinking that they are interchangeable, leading to code like

value = myObject[name];
if (value == null) {
    alert(name + ' not found.');
}

It is comparing the wrong value with the wrong operator. This code works because it contains two errors that cancel each other out. That is a crazy way to program. It is better written like this:

value = myObject[name];
if (value === undefined) {
    alert(name + ' not found.');
}

In XML use:

android:editable="false"

As an example:

<EditText
    android:id="@+id/EditText1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:editable="false" />

I'd do it like this:

[id^="product"] {
  ...
}

Ideally, use a class. This is what classes are for:

<div id="product176" class="product"></div>
<div id="product177" class="product"></div>
<div id="product178" class="product"></div>

And now the selector becomes:

.product {
  ...
}

i tought it's because the connection but i use this:

git push --force origin master

If you want to circumvent this problem you could also use the shelve. Then you would create files that would be the size of your machines capacity to handle, and only put them on the RAM when necessary, basically writing to the HD and pulling the information back in pieces so you can process it.

Create binary file and check if information is already in it if yes make a local variable to hold it else write some data you deem necessary.

Data = shelve.open('File01')
   for i in range(0,100):
     Matrix_Shelve = 'Matrix' + str(i)
     if Matrix_Shelve in Data:
        Matrix_local = Data[Matrix_Shelve]
     else:
        Data[Matrix_Selve] = 'somenthingforlater'

Hope it doesn't sound too arcaic.

Use add

$request->request->add(['img' => $img]);

Edit: The answer below may be satisfactory, but it has some drawbacks:

1. There is a noticeable pause for the running of the script. I'm on a 160 ms latency, and it's enough to be annoying.

2. It works by building a new range each time you edit a given row. This gives an 'invalid contents' to previous entries some of the time

I hope others can clean this up somewhat.

Here's another way to do it, that saves you a ton of range naming:

Three sheets in the worksheet: call them Main, List, and DRange (for dynamic range.) On the Main sheet, column 1 contains a timestamp. This time stamp is modified onEdit.

On List your categories and subcategories are arranged as a simple list. I'm using this for plant inventory at my tree farm, so my list looks like this:

Group   | Genus | Bot_Name
Conifer | Abies | Abies balsamea
Conifer | Abies | Abies concolor
Conifer | Abies | Abies lasiocarpa var bifolia
Conifer | Pinus | Pinus ponderosa
Conifer | Pinus | Pinus sylvestris
Conifer | Pinus | Pinus banksiana
Conifer | Pinus | Pinus cembra
Conifer | Picea | Picea pungens
Conifer | Picea | Picea glauca
Deciduous | Acer | Acer ginnala
Deciduous | Acer | Acer negundo
Deciduous | Salix | Salix discolor
Deciduous | Salix | Salix fragilis
...

Where | indicates separation into columns.
For convenience I also used the headers as names for named ranges.

DRrange A1 has the formula

=Max(Main!A2:A1000)

This returns the most recent timestamp.

A2 to A4 have variations on:

=vlookup($A$1,Inventory!$A$1:$E$1000,2,False) 

with the 2 being incremented for each cell to the right.

On running A2 to A4 will have the currently selected Group, Genus and Species.

Below each of these, is a filter command something like this:

=unique(filter(Bot_Name,REGEXMATCH(Bot_Name,C1)))

These filters will populate a block below with matching entries to the contents of the top cell.

The filters can be modified to suit your needs, and to the format of your list.

Back to Main: Data validation in Main is done using ranges from DRange.

The script I use:

function onEdit(event) {

  //SETTINGS
  var dynamicSheet='DRange'; //sheet where the dynamic range lives
  var tsheet = 'Main'; //the sheet you are monitoring for edits
  var lcol = 2; //left-most column number you are monitoring; A=1, B=2 etc
  var rcol = 5; //right-most column number you are monitoring
  var tcol = 1; //column number in which you wish to populate the timestamp
  //

  var s = event.source.getActiveSheet();
  var sname = s.getName();
  if (sname == tsheet) {
    var r = event.source.getActiveRange();
    var scol = r.getColumn();  //scol is the column number of the edited cell
    if (scol >= lcol && scol <= rcol) {
      s.getRange(r.getRow(), tcol).setValue(new Date());
      for(var looper=scol+1; looper<=rcol; looper++) {
         s.getRange(r.getRow(),looper).setValue(""); //After edit clear the entries to the right
      }
    }
  }
}

Note: This may be obsolete for current versions of Amazon Linux 2 since late 2018 (see comments), you can now directly install it via yum install python3.

In Amazon Linux 2, there isn't a python3[4-6] in the default yum repos, instead there's the Amazon Extras Library.

sudo amazon-linux-extras install python3

If you want to set up isolated virtual environments with it; using yum install'd virtualenv tools don't seem to reliably work.

virtualenv --python=python3 my_venv

Calling the venv module/tool is less finicky, and you could double check it's what you want/expect with python3 --version beforehand.

python3 -m venv my_venv

A simple, but not pure java solution, is to shell out to curl from java, which gives you complete control over how the request is done. If you're just doing this for something simple, this allows you to ignore certificate errors at times, by using this method. This example shows how to make a request against a secure server with a valid or invalid certificate, pass in a cookie, and get the output using curl from java.

import java.io.BufferedReader;
import java.io.File;
import java.io.IOException;
import java.io.InputStreamReader;

public class MyTestClass
{
  public static void main(String[] args) 
  {
    String url = "https://www.google.com";
    String sessionId = "faf419e0-45a5-47b3-96d1-8c62b2a3b558";

    // Curl options are:
    // -k: ignore certificate errors
    // -L: follow redirects
    // -s: non verbose
    // -H: add a http header

    String[] command = { "curl", "-k", "-L", "-s", "-H", "Cookie: MYSESSIONCOOKIENAME=" + sessionId + ";", "-H", "Accept:*/*", url };
    String output = executeShellCmd(command, "/tmp", true, true);
    System.out.println(output);
  }

  public String executeShellCmd(String[] command, String workingFolder, boolean wantsOutput, boolean wantsErrors)
  {
    try
    {

This is finally what did it for me (and triggers a disposition):

function onClick() {_x000D_
  var pdf = new jsPDF('p', 'pt', 'letter');_x000D_
  pdf.canvas.height = 72 * 11;_x000D_
  pdf.canvas.width = 72 * 8.5;_x000D_
_x000D_
  pdf.fromHTML(document.body);_x000D_
_x000D_
  pdf.save('test.pdf');_x000D_
};_x000D_
_x000D_
var element = document.getElementById("clickbind");_x000D_
element.addEventListener("click", onClick);

<h1>Dsdas</h1>_x000D_
_x000D_
<a id="clickbind" href="#">Click</a>_x000D_
<script src="https://cdnjs.cloudflare.com/ajax/libs/jspdf/1.3.3/jspdf.min.js"></script>

And for those of the KnockoutJS inclination, a little binding:

ko.bindingHandlers.generatePDF = {
    init: function(element) {

        function onClick() {
            var pdf = new jsPDF('p', 'pt', 'letter');
            pdf.canvas.height = 72 * 11;
            pdf.canvas.width = 72 * 8.5;

            pdf.fromHTML(document.body);

            pdf.save('test.pdf');                    
        };

        element.addEventListener("click", onClick);
    }
};

DateTime.Date cannot be converted to SQL. Use EntityFunctions.TruncateTime method to get date part.

var eventsCustom = eventCustomRepository
.FindAllEventsCustomByUniqueStudentReference(userDevice.UniqueStudentReference)
.Where(x => EntityFunctions.TruncateTime(x.DateTimeStart) == currentDate.Date);

UPDATE: As @shankbond mentioned in comments, in Entity Framework 6 EntityFunctions is obsolete, and you should use DbFunctions class, which is shipped with Entity Framework.

Int -->String :

public enum Country {

    US("US",0),
    UK("UK",2),
    DE("DE",1);


    private static Map<Integer, String> domainToCountryMapping; 
    private String country;
    private int domain;

    private Country(String country,int domain){
        this.country=country.toUpperCase();
        this.domain=domain;
    }

    public String getCountry(){
        return country;
    }


    public static String getCountry(String domain) {
        if (domainToCountryMapping == null) {
            initMapping();
        }

        if(domainToCountryMapping.get(domain)!=null){
            return domainToCountryMapping.get(domain);
        }else{
            return "US";
        }

    }

     private static void initMapping() {
         domainToCountryMapping = new HashMap<Integer, String>();
            for (Country s : values()) {
                domainToCountryMapping.put(s.domain, s.country);
            }
        }
