Open IIS manager, select Application Pools, select the application pool you are using, click on Advanced Settings in the right-hand menu. Under General, set "Enable 32-Bit Applications" to "True".

Open eclipse.ini in the installation directory, and observe the line with text:

plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.0.200.v20090519 then it is 64 bit.

If it would be plugins/org.eclipse.equinox.launcher.win32.win32.x86_32_1.0.200.v20090519 then it is 32 bit.

If you have a 64-bit OS, instead of i686, you have x86_64 or ia64 in the output of uname -a. In that you do not have any of these two strings; you have a 32-bit OS (note that this does not mean that your CPU is not 64-bit).

To install 32-bit Java on Windows 7 (64-bit OS + Machine). You can do:

1) Download JDK: http://javadl.sun.com/webapps/download/AutoDL?BundleId=58124
2) Download JRE: http://www.java.com/en/download/installed.jsp?jre_version=1.6.0_22&vendor=Sun+Microsystems+Inc.&os=Linux&os_version=2.6.41.4-1.fc15.i686

3) System variable create: C:\program files (x86)\java\jre6\bin\

4) Anywhere you type java -version

it use 32-bit on (64-bit). I have to use this because lots of third party libraries do not work with 64-bit. Java wake up from the hell, give us peach :P. Go-language is killer.

Take a look at limits.h. You can find the specific values for your compiler. INT_MIN and INT_MAX will be of interest.

I should add: You should not be putting your dll's into \system32\ anyway! Modify your code, modify your installer... find a home for your bits that is NOT anywhere under c:\windows\

For example, your installer puts your dlls into:

\program files\<your app dir>\

or

\program files\common files\<your app name>\

(Note: The way you actually do this is to use the environment var: %ProgramFiles% or %ProgramFiles(x86)% to find where Program Files is.... you do not assume it is c:\program files\ ....)

and then sets a registry tag :

HKLM\software\<your app name>
-- dllLocation

The code that uses your dlls reads the registry, then dynamically links to the dlls in that location.

The above is the smart way to go.

You do not ever install your dlls, or third party dlls into \system32\ or \syswow64. If you have to statically load, you put your dlls in your exe dir (where they will be found). If you cannot predict the exe dir (e.g. some other exe is going to call your dll), you may have to put your dll dir into the search path (avoid this if at all poss!)

system32 and syswow64 are for Windows provided files... not for anyone elses files. The only reason folks got into the bad habit of putting stuff there is because it is always in the search path, and many apps/modules use static linking. (So, if you really get down to it, the real sin is static linking -- this is a sin in native code and managed code -- always always always dynamically link!)

In general, when you get an error like this, just do

yum provides ld-linux.so.2

then you'll see something like:

glibc-2.20-5.fc21.i686 : The GNU libc libraries
Repo        : fedora
Matched from:
Provides    : ld-linux.so.2

and then you just run the following like BRPocock wrote (in case you were wondering what the logic was...):

yum install glibc.i686

Try this:
#ifdef _WIN64
// 64 bit code
#elif _WIN32
// 32 bit code
#else
   if(sizeof(void*)==4)

       // 32 bit code
   else 

       // 64 bit code   
#endif

I hate to answer my own questions, but I did finally find a solution that actually works (using socket communication between services may fix the problem, but it creates even more problems). Since our database is legacy, it merely required Microsoft.ACE.OLEDB.12.0 in the connection string. It turns out that this was also included in Office 2007 (and MSDE 2007), where there is only a 32-bit version available. So, instead of installing MSDE 2010 32-bit, we install MSDE 2007, and it works just fine. Other applications can then install 64-bit MSDE 2010 (or 64-bit Office 2010), and it does not conflict with our application.

Thus far, it appears this is an acceptable solution for all Windows OS environments.

In "Path" variable removed "C:\ProgramData\Oracle\Java\javapath" and replaced it with "C:\Program Files\Java\jdk1.8.0_212\bin"

It worked for me.

basically 32bit architecture can address 4GB as you expected. There are some techniques which allows processor to address more data like AWE or PAE.

My problem was that I had the wrong MS Sync FrameWork version (1.0) in my project References. After update to the version 2.1, the error was gone and life is good again.

A crude way would be to call dumpbin with the headers option from the Visual Studio tools on each DLL and look for the appropriate output:

dumpbin /headers my32bit.dll

PE signature found

File Type: DLL

FILE HEADER VALUES
             14C machine (x86)
               1 number of sections
        45499E0A time date stamp Thu Nov 02 03:28:10 2006
               0 file pointer to symbol table
               0 number of symbols
              E0 size of optional header
            2102 characteristics
                   Executable
                   32 bit word machine
                   DLL

OPTIONAL HEADER VALUES
             10B magic # (PE32)

You can see a couple clues in that output that it is a 32 bit DLL, including the 14C value that Paul mentions. Should be easy to look for in a script.

You do not need to use 64bit since windows will emulate 32bit programs using wow64. But using the native version (64bit) will give you more performance.

Search the registry for the install path of the office component you are interested in, e.g. for Excel 2010 look in SOFTWARE(Wow6432Node)\Microsoft\Office\14.0\Excel\InstallRoot. It will only be either in the 32-bit registry or the 64-bit registry not both.

I have the same problem

Microsoft.Jet.OLEDB.4.0' provider is not registered on the local machine

I applied the answer by neo but it did not work until I change the provider to “Provider=Microsoft.ACE.OLEDB.12.0;” in connection string.

Hope this will help if some one face the same issue.

While compiling in RHEL 6.2 (x86_64), I installed both 32bit and 64bit libstdc++-dev packages, but I had the "c++config.h no such file or directory" problem.

Resolution:

The directory /usr/include/c++/4.4.6/x86_64-redhat-linux was missing.

I did the following:

cd /usr/include/c++/4.4.6/
mkdir x86_64-redhat-linux
cd x86_64-redhat-linux
ln -s ../i686-redhat-linux 32

I'm now able to compile 32bit binaries on a 64bit OS.

This is the command for the batch file and it can run the vbscript.

C:\Windows\SysWOW64\cmd.exe /c cscript C:\Windows\SysWOW64\...\necdaily.vbs

You could also use to localStorage feature of HTML5 to store your test value and then access it at any other point in your website by using the localStorage.getItem() method. To see how this works you should look at the w3schools explanation or the explanation from the Opera Developer website. Hope this helps.

The answers provided (at the time of this post) are link only answers so I thought I would summarize the links into an answer and what I will be using.

When working to create Cross Browser Favicons (including touch icons) there are several things to consider.

The first (of course) is Internet Explorer. IE does not support PNG favicons until version 11. So our first line is a conditional comment for favicons in IE 9 and below:

<!--[if IE]><link rel="shortcut icon" href="path/to/favicon.ico"><![endif]-->

To cover the uses of the icon create it at 32x32 pixels. Notice the rel="shortcut icon" for IE to recognize the icon it needs the word shortcut which is not standard. Also we wrap the .ico favicon in a IE conditional comment because Chrome and Safari will use the .ico file if it is present, despite other options available, not what we would like.

The above covers IE up to IE 9. IE 11 accepts PNG favicons, however, IE 10 does not. Also IE 10 does not read conditional comments thus IE 10 won't show a favicon. With IE 11 and Edge available I don't see IE 10 in widespread use, so I ignore this browser.

For the rest of the browsers we are going to use the standard way to cite a favicon:

<link rel="icon" href="path/to/favicon.png">

This icon should be 196x196 pixels in size to cover all devices that may use this icon.

To cover touch icons on mobile devices we are going to use Apple's proprietary way to cite a touch icon:

<link rel="apple-touch-icon-precomposed" href="apple-touch-icon-precomposed.png">

Using rel="apple-touch-icon-precomposed" will not apply the reflective shine when bookmarked on iOS. To have iOS apply the shine use rel="apple-touch-icon". This icon should be sized to 180x180 pixels as that is the current size recommend by Apple for the latest iPhones and iPads. I have read Blackberry will also use rel="apple-touch-icon-precomposed".

As a note: Chrome for Android states:

The apple-touch-* are deprecated, and will be supported only for a short time. (Written as of beta for m31 of Chrome).

Custom Tiles for IE 11+ on Windows 8.1+

IE 11+ on Windows 8.1+ does offer a way to create pinned tiles for your site.

Microsoft recommends creating a few tiles at the following size:

Small: 128 x 128

Medium: 270 x 270

Wide: 558 x 270

Large: 558 x 558

These should be transparent images as we will define a color background next.

Once these images are created you should create an xml file called browserconfig.xml with the following code:

<?xml version="1.0" encoding="utf-8"?>
<browserconfig>
  <msapplication>
    <tile>
      <square70x70logo src="images/smalltile.png"/>
      <square150x150logo src="images/mediumtile.png"/>
      <wide310x150logo src="images/widetile.png"/>
      <square310x310logo src="images/largetile.png"/>
      <TileColor>#009900</TileColor>
    </tile>
  </msapplication>
</browserconfig>

Save this xml file in the root of your site. When a site is pinned IE will look for this file. If you want to name the xml file something different or have it in a different location add this meta tag to the head:

<meta name="msapplication-config" content="path-to-browserconfig/custom-name.xml" />

For additional information on IE 11+ custom tiles and using the XML file visit Microsoft's website.

Putting it all together:

To put it all together the above code would look like this:

<!-- For IE 9 and below. ICO should be 32x32 pixels in size -->
<!--[if IE]><link rel="shortcut icon" href="path/to/favicon.ico"><![endif]-->

<!-- Touch Icons - iOS and Android 2.1+ 180x180 pixels in size. --> 
<link rel="apple-touch-icon-precomposed" href="apple-touch-icon-precomposed.png">

<!-- Firefox, Chrome, Safari, IE 11+ and Opera. 196x196 pixels in size. -->
<link rel="icon" href="path/to/favicon.png">

Windows Phone Live Tiles

If a user is using a Windows Phone they can pin a website to the start screen of their phone. Unfortunately, when they do this it displays a screenshot of your phone, not a favicon (not even the MS specific code referenced above). To make a "Live Tile" for Windows Phone Users for your website one must use the following code:

Here are detailed instructions from Microsoft but here is a synopsis:

Step 1

Create a square image for your website, to support hi-res screens create it at 768x768 pixels in size.

Step 2

Add a hidden overlay of this image. Here is example code from Microsoft:

<div id="TileOverlay" onclick="ToggleTileOverlay()" style='background-color: Highlight; height: 100%; width: 100%; top: 0px; left: 0px; position: fixed; color: black; visibility: hidden'>
  <img src="customtile.png" width="320" height="320" />
  <div style='margin-top: 40px'>
     Add text/graphic asking user to pin to start using the menu...
  </div>
</div>

Step 3

You then can add thew following line to add a pin to start link:

<a href="javascript:ToggleTileOverlay()">Pin this site to your start screen</a>

Microsoft recommends that you detect windows phone and only show that link to those users since it won't work for other users.

Step 4

Next you add some JS to toggle the overlay visibility

<script>
function ToggleTileOverlay() {
 var newVisibility =     (document.getElementById('TileOverlay').style.visibility == 'visible') ? 'hidden' : 'visible';
 document.getElementById('TileOverlay').style.visibility =    newVisibility;
}
</script>

Note on Sizes

I am using one size as every browser will scale down the image as necessary. I could add more HTML to specify multiple sizes if desired for those with a lower bandwidth but I am already compressing the PNG files heavily using TinyPNG and I find this unnecessary for my purposes. Also, according to philippe_b's answer Chrome and Firefox have bugs that cause the browser to load all sizes of icons. Using one large icon may be better than multiple smaller ones because of this.

I had this problem and it was caused by the variables.less file. Overriding it to set the icon-font-path value solved the problem.

The file structured looks like this:

\Content
        \Bootstrap
        \Fonts
 styles.less
 variables.less

Adding my own variables.less file in the root of Content and referencing this in styles.less resolved the 404 error.

Variables.less contains:

@icon-font-path:          "fonts/";

You can't remove API functions without breaking the API. If you would, many applications would no longer compile or run at all.

This is the reason that one reference gives:

Reading a line that overflows the array pointed to by s results in undefined behavior. The use of fgets() is recommended.

AFAIK GrantedAuthority and roles are same in spring security. GrantedAuthority's getAuthority() string is the role (as per default implementation SimpleGrantedAuthority).

For your case may be you can use Hierarchical Roles

<bean id="roleVoter" class="org.springframework.security.access.vote.RoleHierarchyVoter">
    <constructor-arg ref="roleHierarchy" />
</bean>
<bean id="roleHierarchy"
        class="org.springframework.security.access.hierarchicalroles.RoleHierarchyImpl">
    <property name="hierarchy">
        <value>
            ROLE_ADMIN > ROLE_createSubUsers
            ROLE_ADMIN > ROLE_deleteAccounts 
            ROLE_USER > ROLE_viewAccounts
        </value>
    </property>
</bean>

Not the exact sol you looking for, but hope it helps

Edit: Reply to your comment

Role is like a permission in spring-security. using intercept-url with hasRole provides a very fine grained control of what operation is allowed for which role/permission.

The way we handle in our application is, we define permission (i.e. role) for each operation (or rest url) for e.g. view_account, delete_account, add_account etc. Then we create logical profiles for each user like admin, guest_user, normal_user. The profiles are just logical grouping of permissions, independent of spring-security. When a new user is added, a profile is assigned to it (having all permissible permissions). Now when ever user try to perform some action, permission/role for that action is checked against user grantedAuthorities.

Also the defaultn RoleVoter uses prefix ROLE_, so any authority starting with ROLE_ is considered as role, you can change this default behavior by using a custom RolePrefix in role voter and using it in spring security.

A cleaner way to handle file open/close and avoid memory leaks:

Prep:

import numpy as np
import h5py

data_to_write = np.random.random(size=(100,20)) # or some such

Write:

with h5py.File('name-of-file.h5', 'w') as hf:
    hf.create_dataset("name-of-dataset",  data=data_to_write)

Read:

with h5py.File('name-of-file.h5', 'r') as hf:
    data = hf['name-of-dataset'][:]

This is an improvement to a previous answer. It adds support for values with varying lengths and rows with a varying number of cells. For example:

¦Identifier¦     Type¦               Description¦  CPU Credit Use¦Hours¦Balance¦

If you have a file in your repo that it is supposed to be customized by most pullers, then rename the file to something like config.php.template and add config.php to your .gitignore.

You are better off just generating a random long value, then all the bits are random. In Java 6, new Random() uses the System.nanoTime() plus a counter as a seed.

There are different levels of uniqueness.

If you need uniqueness across many machines, you could have a central database table for allocating unique ids, or even batches of unique ids.

If you just need to have uniqueness in one app you can just have a counter (or a counter which starts from the currentTimeMillis()*1000 or nanoTime() depending on your requirements)

Get the flag parameter from the URL string http://cube.wisercapital.com/hf/create?flag=1

public function create(Request $request)
{
$flag = $request->input('flag');
return view('hf.create', compact('page_title', 'page_description', 'flag'));
}

Input. We will start with the text of the input shown in the question since the question did not provide the csv input:

Lines <- "Dates   Bajaj_close Hero_close
3/14/2013   1854.8  1669.1
3/15/2013   1850.3  1684.45

zoo. "ts" class series normally do not represent date indexes but we can create a zoo series that does (see zoo package):

library(zoo)
z <- read.zoo(text = Lines, header = TRUE, format = "%m/%d/%Y")

Alternately, if you have already read this into a data frame DF then it could be converted to zoo as shown on the second line below:

DF <- read.table(text = Lines, header = TRUE)
z <- read.zoo(DF, format = "%m/%d/%Y")

In either case above z ia a zoo series with a "Date" class time index. One could also create the zoo series, zz, which uses 1, 2, 3, ... as the time index:

zz <- z
time(zz) <- seq_along(time(zz))

ts. Either of these could be converted to a "ts" class series:

as.ts(z)
as.ts(zz)

The first has a time index which is the number of days since the Epoch (January 1, 1970) and will have NAs for missing days and the second will have 1, 2, 3, ... as the time index and no NAs.

Monthly series. Typically "ts" series are used for monthly, quarterly or yearly series. Thus if we were to aggregate the input into months we could reasonably represent it as a "ts" series:

z.m <- as.zooreg(aggregate(z, as.yearmon, mean), freq = 12)
as.ts(z.m)

What about ordering desc by the desired property,

   blah = blah.OrderByDescending(x => x.Property);

And then doing something like

  if (!descending)
  {
       blah = blah.Reverse()
  }
  else
  {
      // Already sorted desc ;)
  }

Is it Reverse() too slow?

If running on windows vista or later,
remember to run eclipse under a user with proper file permissions.
try to use the 'Run as Administrator' option.

I think that the shortest, fastest and simplest way would be:

SELECT
    object_name(object_id) AS [Table],
    SUM(row_count) AS [Count]
FROM
    sys.dm_db_partition_stats
WHERE
    --object_schema_name(object_id) = 'dbo' AND 
    index_id < 2
GROUP BY
    object_id

If you were like me, running maven compile deploy from eclipse's maven run configuration, the issue could be related to eclipse's own embedded maven as described in https://bugs.eclipse.org/bugs/show_bug.cgi?id=562847

The workaround is to run mvn compile deploy from CLI such as bash, or to NOT use embedded maven in the eclipse's maven run configuration, and add an external maven (mine is in /usr/share/mvn), and voila, it'll say BUILD SUCCESS.

I researched this just recently and have yet to find a decent date picker that also includes a decent time picker. What I ended up using was eyecon's awesome DatePicker, with two simple dropdowns for time. I was tempted to use Timepickr.js though, looks like a really nice approach.

glOrtho: 2D games, objects close and far appear the same size:

glFrustrum: more real-life like 3D, identical objects further away appear smaller:

Compile:

gcc -ggdb3 -O0 -o main -std=c99 -Wall -Wextra -pedantic main.c -lGL -lGLU -lglut

Run with glOrtho:

./main 1

Run with glFrustrum:

./main

Tested on Ubuntu 18.10.

Schema

Ortho: camera is a plane, visible volume a rectangle:

Frustrum: camera is a point,visible volume a slice of a pyramid:

Image source.

Parameters

We are always looking from +z to -z with +y upwards:

glOrtho(left, right, bottom, top, near, far)

• left: minimum x we see
• right: maximum x we see
• bottom: minimum y we see
• top: maximum y we see
• -near: minimum z we see. Yes, this is -1 times near. So a negative input means positive z.
• -far: maximum z we see. Also negative.

Schema:

Image source.

How it works under the hood

In the end, OpenGL always "uses":

glOrtho(-1.0, 1.0, -1.0, 1.0, -1.0, 1.0);

If we use neither glOrtho nor glFrustrum, that is what we get.

glOrtho and glFrustrum are just linear transformations (AKA matrix multiplication) such that:

• glOrtho: takes a given 3D rectangle into the default cube
• glFrustrum: takes a given pyramid section into the default cube

This transformation is then applied to all vertexes. This is what I mean in 2D:

Image source.

The final step after transformation is simple:

• remove any points outside of the cube (culling): just ensure that x, y and z are in [-1, +1]
• ignore the z component and take only x and y, which now can be put into a 2D screen

With glOrtho, z is ignored, so you might as well always use 0.

One reason you might want to use z != 0 is to make sprites hide the background with the depth buffer.

Deprecation

glOrtho is deprecated as of OpenGL 4.5: the compatibility profile 12.1. "FIXED-FUNCTION VERTEX TRANSFORMATIONS" is in red.

So don't use it for production. In any case, understanding it is a good way to get some OpenGL insight.

Modern OpenGL 4 programs calculate the transformation matrix (which is small) on the CPU, and then give the matrix and all points to be transformed to OpenGL, which can do the thousands of matrix multiplications for different points really fast in parallel.

Manually written vertex shaders then do the multiplication explicitly, usually with the convenient vector data types of the OpenGL Shading Language.

Since you write the shader explicitly, this allows you to tweak the algorithm to your needs. Such flexibility is a major feature of more modern GPUs, which unlike the old ones that did a fixed algorithm with some input parameters, can now do arbitrary computations.

The glFrustum matrix is not too hard to calculate by hand either, but starts getting annoying. Note how frustum cannot be made up with only scaling and translations like glOrtho, more info at: https://gamedev.stackexchange.com/a/118848/25171

The GLM OpenGL C++ math library is a popular choice for calculating such matrices. http://glm.g-truc.net/0.9.2/api/a00245.html documents both an ortho and frustum operations.

I work in Ruby and using Nokogiri I fetch the element and look to see if the result is nil.

require 'nokogiri'

url = "http://somthing.com/resource"

resp = Nokogiri::XML(open(url))

first_name = resp.xpath("/movies/actors/actor[1]/first-name")

puts "first-name not found" if first_name.nil?

You just need to restart your adb. Instruction for that is given in this Link

You are able to cut all odd/even columns by using seq:

This would print all odd columns

echo 1,2,3,4,5,6,7,8,9,10 | cut -d, -f$(seq -s, 1 2 10)

To print all even columns you could use

echo 1,2,3,4,5,6,7,8,9,10 | cut -d, -f$(seq -s, 2 2 10)

By changing the second number of seq you can specify which columns to be printed.

If the specification which columns to print is more complex you could also use a "one-liner-if-clause" like

echo 1,2,3,4,5,6,7,8,9,10 | cut -d, -f$(for i in $(seq 1 10); do if [[ $i -lt 10 && $i -lt 5 ]];then echo -n $i,; else echo -n $i;fi;done)

This would print all columns from 1 to 5 - you can simply modify the conditions to create more complex conditions to specify weather a column shall be printed.

If you are on Windows and have Visual Studio installed you might have something in your PATH that is pointing to an old version of TypeScript. I found that removing the folder "C:\Program Files (x86)\Microsoft SDKs\TypeScript\1.0\" from my PATH (or deleting/renaming this folder) will allow the more recent npm globally installed TypeScript version of tsc to work.

Right click on Sample.java file and delete it. Now go to File -> New -> Class , enter name of program (i.e. hello) , click on finish . It will create file hello.java. Enter source code of program and finallly press ctrl + F11

It's not really a function of git, msys, or bash; every windows console program is stuck using the same cumbersome copy/paste mechanism for historical reasons. Turning on QuickEdit mode can help -- or you can install a nice alternative console like this one, and change your git bash shortcut to use it instead.

The most fundamental problem of your test application is that you call srand once and then call rand one time and exit.

The whole point of srand function is to initialize the sequence of pseudo-random numbers with a random seed.

It means that if you pass the same value to srand in two different applications (with the same srand/rand implementation) then you will get exactly the same sequence of rand() values read after that in both applications.

However in your example application pseudo-random sequence consists only of one element - the first element of a pseudo-random sequence generated from seed equal to current time of 1 sec precision. What do you expect to see on output then?

Obviously when you happen to run application on the same second - you use the same seed value - thus your result is the same of course (as Martin York already mentioned in a comment to the question).

Actually you should call srand(seed) one time and then call rand() many times and analyze that sequence - it should look random.

EDIT:

Oh I get it. Apparently verbal description is not enough (maybe language barrier or something... :) ).

OK. Old-fashioned C code example based on the same srand()/rand()/time() functions that was used in the question:

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

int main(void)
{
    unsigned long j;
    srand( (unsigned)time(NULL) );

    for( j = 0; j < 100500; ++j )
    {
        int n;

        /* skip rand() readings that would make n%6 non-uniformly distributed
          (assuming rand() itself is uniformly distributed from 0 to RAND_MAX) */
        while( ( n = rand() ) > RAND_MAX - (RAND_MAX-5)%6 )
        { /* bad value retrieved so get next one */ }

        printf( "%d,\t%d\n", n, n % 6 + 1 );
    }

    return 0;
}

^^^ THAT sequence from a single run of the program is supposed to look random.

Please NOTE that I don't recommend to use rand/srand functions in production for the reasons explained below and I absolutely don't recommend to use function time as a random seed for the reasons that IMO already should be quite obvious. Those are fine for educational purposes and to illustrate the point sometimes but for any serious use they are mostly useless.

EDIT2:

When using C or C++ standard library it is important to understand that as of now there is not a single standard function or class producing actually random data definitively (guaranteed by the standard). The only standard tool that approaches this problem is std::random_device that unfortunately still does not provide guarantees of actual randomness.

Depending on the nature of application you should first decide if you really need truly random (unpredictable) data. Notable case when you do most certainly need true randomness is information security - e.g. generating symmetric keys, asymmetric private keys, salt values, security tokens, etc.

However security-grade random numbers is a separate industry worth a separate article.

In most cases Pseudo-Random Number Generator is sufficient - e.g. for scientific simulations or games. In some cases consistently defined pseudo-random sequence is even required - e.g. in games you may choose to generate exactly same maps in runtime to avoid storing lots of data.

The original question and reoccurring multitude of identical/similar questions (and even many misguided "answers" to them) indicate that first and foremost it is important to distinguish random numbers from pseudo-random numbers AND to understand what is pseudo-random number sequence in the first place AND to realize that pseudo-random number generators are NOT used the same way you could use true random number generators.

Intuitively when you request random number - the result returned shouldn't depend on previously returned values and shouldn't depend if anyone requested anything before and shouldn't depend in what moment and by what process and on what computer and from what generator and in what galaxy it was requested. That is what word "random" means after all - being unpredictable and independent of anything - otherwise it is not random anymore, right? With this intuition it is only natural to search the web for some magic spells to cast to get such random number in any possible context.

^^^ THAT kind of intuitive expectations IS VERY WRONG and harmful in all cases involving Pseudo-Random Number Generators - despite being reasonable for true random numbers.

While the meaningful notion of "random number" exists (kind of) - there is no such thing as "pseudo-random number". A Pseudo-Random Number Generator actually produces pseudo-random number sequence.

Pseudo-random sequence is in fact always deterministic (predetermined by its algorithm and initial parameters) i.e. there is actually nothing random about it.

When experts talk about quality of PRNG they actually talk about statistical properties of the generated sequence (and its notable sub-sequences). For example if you combine two high quality PRNGs by using them both in turns - you may produce bad resulting sequence - despite them generating good sequences each separately (those two good sequences may simply correlate to each other and thus combine badly).

Specifically rand()/srand(s) pair of functions provide a singular per-process non-thread-safe(!) pseudo-random number sequence generated with implementation-defined algorithm. Function rand() produces values in range [0, RAND_MAX].

Quote from C11 standard (ISO/IEC 9899:2011):

The srand function uses the argument as a seed for a new sequence of pseudo-random numbers to be returned by subsequent calls to rand. If srand is then called with the same seed value, the sequence of pseudo-random numbers shall be repeated. If rand is called before any calls to srand have been made, the same sequence shall be generated as when srand is first called with a seed value of 1.

Many people reasonably expect that rand() would produce a sequence of semi-independent uniformly distributed numbers in range 0 to RAND_MAX. Well it most certainly should (otherwise it's useless) but unfortunately not only standard doesn't require that - there is even explicit disclaimer that states "there is no guarantees as to the quality of the random sequence produced". In some historical cases rand/srand implementation was of very bad quality indeed. Even though in modern implementations it is most likely good enough - but the trust is broken and not easy to recover. Besides its non-thread-safe nature makes its safe usage in multi-threaded applications tricky and limited (still possible - you may just use them from one dedicated thread).

New class template std::mersenne_twister_engine<> (and its convenience typedefs - std::mt19937/std::mt19937_64 with good template parameters combination) provides per-object pseudo-random number generator defined in C++11 standard. With the same template parameters and the same initialization parameters different objects will generate exactly the same per-object output sequence on any computer in any application built with C++11 compliant standard library. The advantage of this class is its predictably high quality output sequence and full consistency across implementations.

Also there are more PRNG engines defined in C++11 standard - std::linear_congruential_engine<> (historically used as fair quality srand/rand algorithm in some C standard library implementations) and std::subtract_with_carry_engine<>. They also generate fully defined parameter-dependent per-object output sequences.

Modern day C++11 example replacement for the obsolete C code above:

#include <iostream>
#include <chrono>
#include <random>

int main()
{
    std::random_device rd;
    // seed value is designed specifically to make initialization
    // parameters of std::mt19937 (instance of std::mersenne_twister_engine<>)
    // different across executions of application
    std::mt19937::result_type seed = rd() ^ (
            (std::mt19937::result_type)
            std::chrono::duration_cast<std::chrono::seconds>(
                std::chrono::system_clock::now().time_since_epoch()
                ).count() +
            (std::mt19937::result_type)
            std::chrono::duration_cast<std::chrono::microseconds>(
                std::chrono::high_resolution_clock::now().time_since_epoch()
                ).count() );

    std::mt19937 gen(seed);

    for( unsigned long j = 0; j < 100500; ++j )
    /* ^^^Yes. Generating single pseudo-random number makes no sense
       even if you use std::mersenne_twister_engine instead of rand()
       and even when your seed quality is much better than time(NULL) */    
    {
        std::mt19937::result_type n;
        // reject readings that would make n%6 non-uniformly distributed
        while( ( n = gen() ) > std::mt19937::max() -
                                    ( std::mt19937::max() - 5 )%6 )
        { /* bad value retrieved so get next one */ }

        std::cout << n << '\t' << n % 6 + 1 << '\n';
    }

    return 0;
}

The version of previous code that uses std::uniform_int_distribution<>

#include <iostream>
#include <chrono>
#include <random>

int main()
{
    std::random_device rd;
    std::mt19937::result_type seed = rd() ^ (
            (std::mt19937::result_type)
            std::chrono::duration_cast<std::chrono::seconds>(
                std::chrono::system_clock::now().time_since_epoch()
                ).count() +
            (std::mt19937::result_type)
            std::chrono::duration_cast<std::chrono::microseconds>(
                std::chrono::high_resolution_clock::now().time_since_epoch()
                ).count() );

    std::mt19937 gen(seed);
    std::uniform_int_distribution<unsigned> distrib(1, 6);

    for( unsigned long j = 0; j < 100500; ++j )
    {
        std::cout << distrib(gen) << ' ';
    }

    std::cout << '\n';
    return 0;
}

How and where is app.run() used? After module definition or after app.config(), after app.controller()?

Where:

In your package.js E.g. /packages/dashboard/public/controllers/dashboard.js

How:

Make it look like this

var app = angular.module('mean.dashboard', ['ui.bootstrap']);

app.controller('DashboardController', ['$scope', 'Global', 'Dashboard',
    function($scope, Global, Dashboard) {
        $scope.global = Global;
        $scope.package = {
            name: 'dashboard'
        };
        // ...
    }
]);

app.run(function(editableOptions) {
    editableOptions.theme = 'bs3'; // bootstrap3 theme. Can be also 'bs2', 'default'
});

curlPost('google.com', [
    'username' => 'admin',
    'password' => '12345',
]);


function curlPost($url, $data) {
    $ch = curl_init($url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
    $response = curl_exec($ch);
    $error = curl_error($ch);
    curl_close($ch);
    if ($error !== '') {
        throw new \Exception($error);
    }

    return $response;
}

If you are still trying to put files relative to your executable instead of in the temp directory, you need to copy it yourself. This is how I ended up getting it done.

https://stackoverflow.com/a/59415662/999943

You add a step in the spec file that does a filesystem copy to the DISTPATH variable.

Hope that helps.

ANSI C99/C11 don't include an extra printf conversion specifier for bool.

But the GNU C library provides an API for adding custom specifiers.

An example:

#include <stdio.h>
#include <printf.h>
#include <stdbool.h>

static int bool_arginfo(const struct printf_info *info, size_t n,
    int *argtypes, int *size)
{
  if (n) {
    argtypes[0] = PA_INT;
    *size = sizeof(bool);
  }
  return 1;
}
static int bool_printf(FILE *stream, const struct printf_info *info,
    const void *const *args)
{
  bool b =  *(const bool*)(args[0]);
  int r = fputs(b ? "true" : "false", stream);
  return r == EOF ? -1 : (b ? 4 : 5);
}
static int setup_bool_specifier()
{
  int r = register_printf_specifier('B', bool_printf, bool_arginfo);
  return r;
}
int main(int argc, char **argv)
{
  int r = setup_bool_specifier();
  if (r) return 1;
  bool b = argc > 1;
  r = printf("The result is: %B\n", b);
  printf("(written %d characters)\n", r);
  return 0;
}

Since it is a glibc extensions the GCC warns about that custom specifier:

$ gcc -Wall -g    main.c   -o main
main.c: In function ‘main’:
main.c:34:3: warning: unknown conversion type character ‘B’ in format [-Wformat=]
   r = printf("The result is: %B\n", b);
   ^
main.c:34:3: warning: too many arguments for format [-Wformat-extra-args]

Output:

$ ./main
The result is: false
(written 21 characters)
$ ./main 1
The result is: true
(written 20 characters)

I got this error while trying to host a WCF service in an empty ASP.NET application. The whole solution was using .NET 4.5 platform, on IIS 8.5 running on Windows 8.1. The gotcha was to

1. Open up "Turn Windows Features on or off"

2. Go to WCF section under ASP.NET 4.5 advanced services

3. Check HTTP Activation.

4. You'll be asked to restart the system.

   

This should Fix the HTTP 500.19!

EDIT 11-FEB-2016 Just got an issue on Windows 10 Pro, IIS 10, This time, it was an HTTP 404.0. The fix is still the same, turn on "HTTP Activation" under Windows Features -> .NET Framework 4.6 Advanced Services -> WCF Services -> HTTP Activation

The answers didn't work for me with postgresql 9.1+

This is what I had to do (you can check more in the manual here)

UPDATE schema.TableA as A
SET "columnA" = "B"."columnB"
FROM schema.TableB as B
WHERE A.id = B.id;

You can omit the schema, if you are using the default schema for both tables.

Also it'd work to just specify ifelse() twice:

plot(pos,cn, col= ifelse(cn >= 3, "red", ifelse(cn <= 1,"blue", "black")), ylim = c(0, 10))

Posting another alternative to be more complete. When I tried the "pre" based answers, they added extra vertical line breaks as well.

Each tab can be converted to a sequence non-breaking spaces which require no wrapping.

"    " 

This is not recommended for repeated/extensive use within a page. A div margin/padding approach would appear much cleaner.

If Ubuntu try opening All Settings > Network > Network proxy set the method to automatic and save.

To enable your app to listen for both http and https on ports 80 and 443 respectively, do the following

Create an express app:

var express = require('express');
var app = express();

The app returned by express() is a JavaScript function. It can be be passed to Node’s HTTP servers as a callback to handle requests. This makes it easy to provide both HTTP and HTTPS versions of your app using the same code base.

You can do so as follows:

var express = require('express');
var https = require('https');
var http = require('http');
var fs = require('fs');
var app = express();

var options = {
  key: fs.readFileSync('/path/to/key.pem'),
  cert: fs.readFileSync('/path/to/cert.pem')
};

http.createServer(app).listen(80);
https.createServer(options, app).listen(443);

Since you seem to be on windows you can do this so python <filename.py>. Check that python's bin folder is in your PATH, or you can do c:\python23\bin\python <filename.py>. Python is an interpretive language and so you need the interpretor to run your file, much like you need java runtime to run a jar file.

In order to run scripts, you should write the "python test.py" command in the command prompt, and not within the python shell. also, the test.py file should be at the path you run from in the cli.

Try the following:

• Close Eclipse.
• Restart your phone.
• End adb.exe process in Task Manager (Windows). In Mac, force close in Activity Monitor.
• Issue kill and start command in \platform-tools\
  • C:\sdk\platform-tools>adb kill-server
  • C:\sdk\platform-tools>adb start-server
• If it says something like 'started successfully', you are good.

And, just to throw it in the mix, is the oft-forgotten str.translate which will work a lot faster than looping/regular expressions:

For Python 2:

from string import digits

s = 'abc123def456ghi789zero0'
res = s.translate(None, digits)
# 'abcdefghizero'

For Python 3:

from string import digits

s = 'abc123def456ghi789zero0'
remove_digits = str.maketrans('', '', digits)
res = s.translate(remove_digits)
# 'abcdefghizero'

I prefer This One

document.forms['idOfTheForm'].nameOfTheInputFiled.value;

You don't need to declare the variable. Ajax success function automatically takes up to 3 parameters: Function( Object data, String textStatus, jqXHR jqXHR )

Using the library Datejs you can accomplish this quite elegantly, with its toString format specifiers: http://jsfiddle.net/TeRnM/1/.

var date = new Date(1324339200000);

date.toString("MMM dd"); // "Dec 20"

Try using

cat kb.txt | sed -e 's/\s$//g'

its pretty simple

  Date someDate = new DateTime();
  string timeOfDay = someDate.ToString("hh:mm tt"); 
  // hh - shows hour and mm - shows minute - tt - shows AM or PM

First, you can calculate the group means with aggregate:

means <- aggregate(weight ~  group, PlantGrowth, mean)

This dataset can be used with geom_text:

library(ggplot2)
ggplot(data=PlantGrowth, aes(x=group, y=weight, fill=group)) + geom_boxplot() +
  stat_summary(fun.y=mean, colour="darkred", geom="point", 
               shape=18, size=3,show_guide = FALSE) + 
  geom_text(data = means, aes(label = weight, y = weight + 0.08))

Here, + 0.08 is used to place the label above the point representing the mean.

An alternative version without ggplot2:

means <- aggregate(weight ~  group, PlantGrowth, mean)

boxplot(weight ~ group, PlantGrowth)
points(1:3, means$weight, col = "red")
text(1:3, means$weight + 0.08, labels = means$weight)

//Here is some simple sample code for update

//First declare this

private DatabaseAppHelper dbhelper;
private SQLiteDatabase db;

//initialize the following

dbhelper=new DatabaseAppHelper(this);
        db=dbhelper.getWritableDatabase();

//updation code

 ContentValues values= new ContentValues();
                values.put(DatabaseAppHelper.KEY_PEDNAME, ped_name);
                values.put(DatabaseAppHelper.KEY_PEDPHONE, ped_phone);
                values.put(DatabaseAppHelper.KEY_PEDLOCATION, ped_location);
                values.put(DatabaseAppHelper.KEY_PEDEMAIL, ped_emailid);
                db.update(DatabaseAppHelper.TABLE_NAME, values,  DatabaseAppHelper.KEY_ID + "=" + ?, null);

//put ur id instead of the 'question mark' is a function in my shared preference.

Or you can use this one http://plugins.jquery.com/project/parseQuery, it's smaller than most (minified 449 bytes), returns an object representing name-value pairs.

Isn't string.replace returning a value, rather than modifying the source string?

So if you wanted to modify variableABC, you'd need to do this:

var variableABC = "A B C";

variableABC = variableABC.replace('B', 'D') //output: 'A D C'

I had exactly the same problem try to put the two classes in the same package and add line in the pom.xml

As a contemporary alternative, there is a standard now for client side cryptography. This has the advantage of being optimised by the browser itself.

Taken from the example in the documentation:

async function sha256(message) {

    // encode as UTF-8
    const msgBuffer = new TextEncoder('utf-8').encode(message);

    // hash the message
    const hashBuffer = await crypto.subtle.digest('SHA-256', msgBuffer);

    // convert ArrayBuffer to Array
    const hashArray = Array.from(new Uint8Array(hashBuffer));

    // convert bytes to hex string
    const hashHex = hashArray.map(b => ('00' + b.toString(16)).slice(-2)).join('');
    return hashHex;
}

sha256('abc').then(hash => console.log(hash));

(async function() {
    const hash = await sha256('abc');
}());

MD5 is likely unsupported, however the likes of SHA-256, SHA-384, and SHA-512 are.

And those will likely be able to be calculated server side also.

Here's some documentation on usage: https://developer.mozilla.org/en-US/docs/Web/API/SubtleCrypto/digest

And cross browser compatibility: https://caniuse.com/#feat=cryptography

If the format of the id's in the two table varies then you want to join them, as such you can select to use an id from one-main table, say if you have table_customes and table_orders, and tha id for orders is like "101","102"..."110", just use one for customers

select customers.id, name, amount, date from customers.orders;

You can also:

[UIView animateWithDuration:1.0
                 animations:^{ self.view.alpha = 1.1; /* Some fake chages */ }
                 completion:^(BOOL finished)
{
    NSLog(@"A second lapsed.");
}];

This case you have to fake some changes to some view to get the animation work. It is hacky indeed, but I love the block based stuff. Or wrap up @mcfedr answer below.

waitFor(1.0, ^
{
    NSLog(@"A second lapsed");
});

typedef void (^WaitCompletionBlock)();
void waitFor(NSTimeInterval duration, WaitCompletionBlock completion)
{
    dispatch_after(dispatch_time(DISPATCH_TIME_NOW, duration * NSEC_PER_SEC),
                   dispatch_get_main_queue(), ^
    { completion(); });
}

you can simply use

startDate: 'today'

it working fine for me.

int *p=(int *)0x1234 = 10; //0x1234 is the memory address and value 10 is assigned in that address


unsigned int *ptr=(unsigned int *)0x903jf = 20;//0x903j is memory address and value 20 is assigned 

Basically in Embedded platform we are using directly addresses instead of names

In drawable I use this xml code to define the border and background:

<shape xmlns:android="http://schemas.android.com/apk/res/android"> 
  <stroke android:width="4dp" android:color="#D8FDFB" /> 
  <padding android:left="7dp" android:top="7dp" 
    android:right="7dp" android:bottom="7dp" /> 
  <corners android:radius="4dp" /> 
  <solid android:color="#f0600000"/> 
</shape> 

use this for horizontal divider

<View
    android:layout_width="1dp"
    android:layout_height="match_parent"
    android:background="@color/honeycombish_blue" />

and this for vertical divider

<View
    android:layout_width="match_parent"
    android:layout_height="1dp"
    android:background="@color/honeycombish_blue" />

OR if you can use the LinearLayout divider, for horizontal divider

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" >
    <size android:height="1dp"/>
    <solid android:color="#f6f6f6"/>
</shape>

and in LinearLayout

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:divider="@drawable/divider"
    android:orientation="vertical"
    android:showDividers="middle" >

If you want to user vertical divider then in place of android:height="1dp" in shape use android:width="1dp"

Tip: Don't forget the android:showDividers item.

    $youtube_id = $match[1];

echo $youtube_id;

You should pass a Class...

private void foo(Class<?> t){
    if(t == String.class){ ... }
    else if(t == int.class){ ... }
}

private void bar()
{
   foo(String.class);
}

For python2 you can also do this

'%(author)s in %(publication)s'%{'author':unicode(self.author),
                                  'publication':unicode(self.publication)}

which is handy if you have a lot of arguments to substitute (particularly if you are doing internationalisation)

Python2.6 onwards supports .format()

'{author} in {publication}'.format(author=self.author,
                                   publication=self.publication)

The difference between those will depend largely on what browser you are currently referring to. Each one implements these properties differently, or not at all. Quirksmode has great documentation regarding browser differences in regards to W3C standards like the DOM and JavaScript Events.

If you want to submit a POST request

1. You have to set the “request header” section of the Firefox plugin to have a “name” = “Content-Type” and “value” = “application/x-www-form-urlencoded”
2. Now, you are able to submit parameter like “name=mynamehere&title=TA” in the “request body” text area field

Hey, if BASIC is good enough for Gorillas, it's good enough for me.

It's actually something that can be done using a combination of the current stack-trace data, and reflection.

public void MyMethod()
{
     StackTrace stackTrace = new System.Diagnostics.StackTrace();
     StackFrame frame = stackTrace.GetFrames()[1];
     MethodInfo method = frame.GetMethod();
     string methodName = method.Name;
     Type methodsClass = method.DeclaringType;
}

The 1 index on the StackFrame array will give you the method which called MyMethod

.button{
    background-image:url('/image/btn.png');
    background-repeat:no-repeat;
}

If you want to terminate the thread, then just returning is fine. You do NOT need to call Thread.currentThread().interrupt() (it will not do anything bad though. It's just that you don't need to.) This is because interrupt() is basically used to notify the owner of the thread (well, not 100% accurate, but sort of). Because you are the owner of the thread, and you decided to terminate the thread, there is no one to notify, so you don't need to call it.

By the way, why in the first case we need to use currentThread? Is Thread does not refer to the current thread?

Yes, it doesn't. I guess it can be confusing because e.g. Thread.sleep() affects the current thread, but Thread.sleep() is a static method.

If you are NOT the owner of the thread (e.g. if you have not extended Thread and coded a Runnable etc.) you should do

Thread.currentThread().interrupt();
return;

This way, whatever code that called your runnable will know the thread is interrupted = (normally) should stop whatever it is doing and terminate. As I said earlier, it is just a mechanism of communication though. The owner might simply ignore the interrupted status and do nothing.. but if you do set the interrupted status, somebody might thank you for that in the future.

For the same reason, you should never do

Catch(InterruptedException ie){
     //ignore
}

Because if you do, you are stopping the message there. Instead one should do

Catch(InterruptedException ie){
    Thread.currentThread().interrupt();//preserve the message
    return;//Stop doing whatever I am doing and terminate
}

The definitions for NP complete problems above is correct, but I thought I might wax lyrical about their philosophical importance as nobody has addressed that issue yet.

Almost all complex problems you'll come up against will be NP Complete. There's something very fundamental about this class, and which just seems to be computationally different from easily solvable problems. They sort of have their own flavour, and it's not so hard to recognise them. This basically means that any moderately complex algorithm is impossible for you to solve exactly -- scheduling, optimising, packing, covering etc.

But not all is lost if a problem you'll encounter is NP Complete. There is a vast and very technical field where people study approximation algorithms, which will give you guarantees for being close to the solution of an NP complete problem. Some of these are incredibly strong guarantees -- for example, for 3sat, you can get a 7/8 guarantee through a really obvious algorithm. Even better, in reality, there are some very strong heuristics, which excel at giving great answers (but no guarantees!) for these problems.

Note that two very famous problems -- graph isomorphism and factoring -- are not known to be P or NP.

Date has the time as well, just add HH:mm:ss to the date format:

import java.text.SimpleDateFormat
def date = new Date()
def sdf = new SimpleDateFormat("MM/dd/yyyy HH:mm:ss")
println sdf.format(date)

In case you are using JRE 8 you can use LoaclDateTime:

import java.time.*

LocalDateTime t = LocalDateTime.now();
return t as String

The solution that worked for me: If you have Sqldeveloper with java incorporated, you can use the \sqldeveloper\bin\sqldeveloper.bat to launch sqldeveloper as told here.

You can either: Write a server-side script page like PHP, JSP, ASP.net etc to generate this HTML dynamically

or

Setup the web-server that you are using (e.g. Apache) to do exactly that automatically for directories that doesn't contain welcome-page (e.g. index.html)

Specifically in apache read more here: Edit the httpd.conf: http://justlinux.com/forum/showthread.php?s=&postid=502789#post502789 (updated link: https://forums.justlinux.com/showthread.php?94230-Make-apache-list-directory-contents&highlight=502789)

or add the autoindex mod: http://httpd.apache.org/docs/current/mod/mod_autoindex.html

if I got your question correct...

main() method is defined in the class below...

public class ToBeCalledClass{

   public static void main (String args[ ]) {

you want to call this main method in another class.

public class CallClass{

    public void call(){
       ToBeCalledClass.main(null);
    }
}

I did this:

import re

def requirements(filename):
    with open(filename) as f:
        ll = f.read().splitlines()
    d = {}
    for l in ll:
        k, v = re.split(r'==|>=', l)
        d[k] = v
    return d

def packageInfo():
    try:
        from pip._internal.operations import freeze
    except ImportError:
        from pip.operations import freeze

    d = {}
    for kv in freeze.freeze():
        k, v = re.split(r'==|>=', kv)
        d[k] = v
    return d

req = getpackver('requirements.txt')
pkginfo = packageInfo()

for k, v in req.items():
    print(f'{k:<16}: {v:<6} -> {pkginfo[k]}')

I'm a newbie in Ansible, but I would suggest next solution:

playbook.yml

...
vars:
  command_output_full:
    stdout: will be overriden below
  command_output: {{ command_output_full.stdout }}
...
...
...
tasks:
  - name: Create variable from command
    command: "echo Hello"
    register: command_output_full
  - debug: msg="{{ command_output }}"

It should work (and works for me) because Ansible uses lazy evaluation. But it seems it checks validity before the launch, so I have to define command_output_full.stdout in vars.

And, of course, if it is too many such vars in vars section, it will look ugly.

Be sure to use quotes if there are spaces in the file path:

move "C:\Users\MyName\My Old Folder\*" "C:\Users\MyName\My New Folder"

That will move the contents of C:\Users\MyName\My Old Folder\ to C:\Users\MyName\My New Folder

The accepted answer does not show 0 in integer place on giving input like 0.299. It shows .3 in WPF UI. So my suggestion to use following string format

<TextBox Text="{Binding Value,  StringFormat={}{0:#,0.0}}" 

I was looking for the same but couldn't find it, so I make a small script in PHP, you can find it at: http://tequilaphp.wordpress.com/2010/07/05/searching-strings-in-a-database-and-files/

Good luck! (I remove some private code, let me know if I didn't break it in the process :D)

From the composer help create-project command

The create-project command creates a new project from a given
package into a new directory. If executed without params and in a directory with a composer.json file it installs the packages for the current project.
You can use this command to bootstrap new projects or setup a clean
version-controlled installation for developers of your project.

[version]
You can also specify the version with the package name using = or : as separator.
To install unstable packages, either specify the version you want, or use the --stability=dev (where dev can be one of RC, beta, alpha or dev).

This command works:

composer create-project laravel/laravel=4.1.27 your-project-name --prefer-dist

This works with the * notation.

Consider the case in which a service worker acts as an agnostic cache. Your only goal is serve the same resources that you would get from the network, but faster. Of course you can't ensure all the resources will be part of your origin (consider libraries served from CDNs, for instance). As the service worker has the potential of altering network responses, you need to guarantee you are not interested in the contents of the response, nor on its headers, nor even on the result. You're only interested on the response as a black box to possibly cache it and serve it faster.

This is what { mode: 'no-cors' } was made for.

Have a look at the following code snippet. You have mentioned Most files will be 30-40 MB. This claims to read 180 MB in 1.4 seconds on an Intel Quad Core:

private int _bufferSize = 16384;

private void ReadFile(string filename)
{
    StringBuilder stringBuilder = new StringBuilder();
    FileStream fileStream = new FileStream(filename, FileMode.Open, FileAccess.Read);

    using (StreamReader streamReader = new StreamReader(fileStream))
    {
        char[] fileContents = new char[_bufferSize];
        int charsRead = streamReader.Read(fileContents, 0, _bufferSize);

        // Can't do much with 0 bytes
        if (charsRead == 0)
            throw new Exception("File is 0 bytes");

        while (charsRead > 0)
        {
            stringBuilder.Append(fileContents);
            charsRead = streamReader.Read(fileContents, 0, _bufferSize);
        }
    }
}

hmm, try doing CAST(' ' AS TEXT) + [myText]

Although, i am not completely sure how this will pan out.

I also suggest against using the Text datatype, use varchar instead.

If that doesn't work, try ' ' + CAST ([myText] AS VARCHAR(255))

Updated 2018-06-08: My previous answer was a bit of hack so I have come back and looked at this again. This is a cleaner Jinja2 approach.

- name: Set fact 4
  set_fact:
    foo: "{% for i in foo_result.results %}{% do foo.append(i) %}{% endfor %}{{ foo }}"

I am adding this answer as current best answer for Ansible 2.2+ does not completely cover the original question. Thanks to Russ Huguley for your answer this got me headed in the right direction but it left me with a concatenated string not a list. This solution gets a list but becomes even more hacky. I hope this gets resolved in a cleaner manner.

- name: build foo_string
  set_fact:
    foo_string: "{% for i in foo_result.results %}{{ i.ansible_facts.foo_item }}{% if not loop.last %},{% endif %}{%endfor%}"

- name: set fact foo
  set_fact:
    foo: "{{ foo_string.split(',') }}"

Since Android 7.0 you can use adb shell cmd package resolve-activity command to get the default activity of an installed app like this:

adb shell "cmd package resolve-activity --brief com.google.android.calculator | tail -n 1"
com.google.android.calculator/com.android.calculator2.Calculator

I had a similar problem when I tried to create the React Axios instance.

I resolved it using the below approach.

const instance = axios.create({
  baseURL: "https://jsonplaceholder.typicode.com/",
  withCredentials: false,
  headers: {
    'Access-Control-Allow-Origin' : '*',
    'Access-Control-Allow-Methods':'GET,PUT,POST,DELETE,PATCH,OPTIONS',
    }
});

I heard a good description (parable) which illustrates ports as different delivery points for a large building, e.g. Post office for letters and small parcels, Goods In for large deliveries / pallets, Doors for people.

SELECT * FROM a WHERE a.group_id IN 
(SELECT group_id FROM b WHERE b.user_id!=$_SESSION{'[user_id']} AND b.group_id = a.group_id)
WHERE a.keyword LIKE '%".$keyword."%';

If you are returning ActionResult in .net core web api, or IHttpAction result then you can just wrap up your model in an Ok() method which will match the case on your front end and serialise it for you. No need to use JsonConvert. :)

If you're live watching if unloading class worked in JConsole or something, try also adding java.lang.System.gc() at the end of your class unloading logic. It explicitly triggers Garbage Collector.

X-code is primarily made for OS-X or iPhone development on Mac systems. Versions for Windows are not available. However this might help!

There is no way to get Xcode on Windows; however you can use a different SDK like Corona instead although it will not use Objective-C (I believe it uses Lua). I have however heard that it is horrible to use.

For people having the same error with a similar code:

$(function(){
    var app = angular.module("myApp", []); 
    app.controller('myController', function(){

    });
});

Removing the $(function(){ ... }); solved the error.

select count(*) from dbo.tablename where address_line_1 LIKE '%[\'']%' {eSCAPE'\'}

(B)|(A)

then use what group 2 captures...

Here is sample code that might help you coping Column A to Column B:

UPDATE YourTable
SET ColumnB = ColumnA
WHERE
ColumnB IS NULL
AND ColumnA IS NOT NULL;

Try looking into Gatekeeper. I am not sure of too much Mac stuff, but I heard that you can enable it in there.

DISCLAMER: Following code creates different threads for each function.

This might be useful for some of the cases as it is simpler to use. But know that it is not async but gives illusion of async using multiple threads, even though decorator suggests that.

You can use the following decorator to give a callback once the execution of function is completed, the callback must handle the processing of data returned by the function.

Please note that after the function is decorated it will return a Future object.

import asyncio

## Decorator implementation of async runner !!
def run_async(callback, loop=None):
    if loop is None:
        loop = asyncio.get_event_loop()

    def inner(func):
        def wrapper(*args, **kwargs):
            def __exec():
                out = func(*args, **kwargs)
                callback(out)
                return out

            return loop.run_in_executor(None, __exec)

        return wrapper

    return inner

Example of implementation:

urls = ["https://google.com", "https://facebook.com", "https://apple.com", "https://netflix.com"]
loaded_urls = []  # OPTIONAL, used for showing realtime, which urls are loaded !!


def _callback(resp):
    print(resp.url)
    print(resp)
    loaded_urls.append((resp.url, resp))  # OPTIONAL, used for showing realtime, which urls are loaded !!


# Must provide a callback function, callback func will be executed after the func completes execution
# Callback function will accept the value returned by the function.
@run_async(_callback)
def get(url):
    return requests.get(url)


for url in urls:
    get(url)

If you wish to see which url are loaded in real-time then, you can add the following code at the end as well:

while True:
    print(loaded_urls)
    if len(loaded_urls) == len(urls):
        break

"Visual Studio does not support std::cout as debug tool for non-console applications"
_{- from Marius Amado-Alves' answer to "How can I see cout output in a non-console application?"}

Which means if you use it, Visual Studio shows nothing in the "output" window (in my case VS2008)

You can use:

overflow:hidden;

to hide the text outside the zone.

Note that it may cut the last letter (so a part of the last letter will still be displayed). A nicer way is to display an ellipsis at the end. You can do it by using text-overflow:

overflow: hidden;
white-space: nowrap; /* Don't forget this one */
text-overflow: ellipsis;

Solution based on @Elnoor answer, but working with multiple file upload form input and without the "fakepath hack":

HTML:

<div class="custom-file">
    <input id="logo" type="file" class="custom-file-input" multiple>
    <label for="logo" class="custom-file-label text-truncate">Choose file...</label>
</div>

JS:

$('input[type="file"]').on('change', function () {
    let filenames = [];
    let files = document.getElementById('health_claim_file_form_files').files;

    for (let i in files) {
        if (files.hasOwnProperty(i)) {
            filenames.push(files[i].name);
        }
    }

    $(this).next('.custom-file-label').addClass("selected").html(filenames.join(',    '));
});

This is made to assign a default value, in this case the value of y, if the x variable is falsy.

The boolean operators in JavaScript can return an operand, and not always a boolean result as in other languages.

The Logical OR operator (||) returns the value of its second operand, if the first one is falsy, otherwise the value of the first operand is returned.

For example:

"foo" || "bar"; // returns "foo"
false || "bar"; // returns "bar"

Falsy values are those who coerce to false when used in boolean context, and they are 0, null, undefined, an empty string, NaN and of course false.

If you want to set the active tab by ID instead of index, you can also use the following:

$('#tabs').tabs({ active: $('#tabs ul').index($('#tab-101')) });

In Sql Server 2012 - Management Studio:

Solution 1:

Execute the query

Right click the Results Window

Select Save Results As from the menu

Select CSV

Solution 2:

Right click on database

Select Tasks, Export Data

Select Source DB

Select Destination: Flat File Destination

Pick a file name

Select Format - Delimited

Choose a table or write a query

Pick a Column delimiter

Note: You can pick a Text qualifier that will delimit your text fields, such as quotes.

If you have a field with commas, don't use you use comma as a delimiter, because it does not escape commas. You can pick a column delimiter such as Vertical Bar: | instead of comma, or a tab character. Otherwise, write a query that escapes your commas or delimits your varchar field.

The escape character or text qualifier you need to use depends on your requirements.

using padding pad

In order to move the colorbar relative to the subplot, one may use the pad argument to fig.colorbar.

import matplotlib.pyplot as plt
import numpy as np; np.random.seed(1)

fig, ax = plt.subplots(figsize=(4,4))
im = ax.imshow(np.random.rand(11,16))
ax.set_xlabel("x label")

fig.colorbar(im, orientation="horizontal", pad=0.2)
plt.show()

using an axes divider

One can use an instance of make_axes_locatable to divide the axes and create a new axes which is perfectly aligned to the image plot. Again, the pad argument would allow to set the space between the two axes.

import matplotlib.pyplot as plt
from mpl_toolkits.axes_grid1 import make_axes_locatable
import numpy as np; np.random.seed(1)

fig, ax = plt.subplots(figsize=(4,4))
im = ax.imshow(np.random.rand(11,16))
ax.set_xlabel("x label")

divider = make_axes_locatable(ax)
cax = divider.new_vertical(size="5%", pad=0.7, pack_start=True)
fig.add_axes(cax)
fig.colorbar(im, cax=cax, orientation="horizontal")

plt.show()

using subplots

One can directly create two rows of subplots, one for the image and one for the colorbar. Then, setting the height_ratios as gridspec_kw={"height_ratios":[1, 0.05]} in the figure creation, makes one of the subplots much smaller in height than the other and this small subplot can host the colorbar.

import matplotlib.pyplot as plt
import numpy as np; np.random.seed(1)

fig, (ax, cax) = plt.subplots(nrows=2,figsize=(4,4), 
                  gridspec_kw={"height_ratios":[1, 0.05]})
im = ax.imshow(np.random.rand(11,16))
ax.set_xlabel("x label")

fig.colorbar(im, cax=cax, orientation="horizontal")

plt.show()

We got this error because we forgot to multiply by sizeof(int). Note the argument to malloc(..) is a number of bytes, not number of machine words or whatever.

looks good enough as a generic version. You can modify it to meet your needs, if they're specific enough.

also test for exceptions and error conditions, such as file doesn't exist or can't be read, etc.

you can also do the following to save some space:

 byte[] bytes = System.IO.File.ReadAllBytes(filename);

Should we include a little JS? Because CSS was not basically created for this job. CSS was just a style sheet to add styles to the HTML, but its pseudo classes can do something that the basic CSS can't do. For example button:active active is pseudo.

Reference:

http://css-tricks.com/pseudo-class-selectors/ You can learn more about pseudo here!

Your code:

The code that you're having the basic but helpfull. And yes :active will only occur once the click event is triggered.

button {
font-size: 18px;
border: 2px solid gray;
border-radius: 100px;
width: 100px;
height: 100px;
}

button:active {
font-size: 18px;
border: 2px solid red;
border-radius: 100px;
width: 100px;
height: 100px;
}

This is what CSS would do, what rlemon suggested is good, but that would as he suggested would require a tag.

How to use CSS:

You can use :focus too. :focus would work once the click is made and would stay untill you click somewhere else, this was the CSS, you were trying to use CSS, so use :focus to make the buttons change.

What JS would do:

The JavaScript's jQuery library is going to help us for this code. Here is the example:

$('button').click(function () {
  $(this).css('border', '1px solid red');
}

This will make sure that the button stays red even if the click gets out. To change the focus type (to change the color of red to other) you can use this:

$('button').click(function () {
  $(this).css('border', '1px solid red');
  // find any other button with a specific id, and change it back to white like
  $('button#red').css('border', '1px solid white');
}

This way, you will create a navigation menu. Which will automatically change the color of the tabs as you click on them. :)

Hope you get the answer. Good luck! Cheers.

Try

SELECT (str(range) + "-" + str(range + 9) ) AS [Score range], COUNT(score) AS [number of occurances]
FROM (SELECT  score,  int(score / 10 ) * 10  AS range  FROM scoredata )  
GROUP BY range;

I had this problem in an abstract generic class. In this particular case, the solution is simpler:

abstract class Foo<T> {
    abstract Class<T> getTClass();
    //...
}

and later on the derived class:

class Bar extends Foo<Whatever> {
    @Override
    Class<T> getTClass() {
        return Whatever.class;
    }
}

On my Galaxy Nexus with Android 4.2.2, I had the same problem initially, 'adb devices' was showing the device but with offline status (USB debugging was initially active on my device).

These are the steps I took to remedy the situation :

1. Disable USB debugging (Device not connected to PC)
2. Re enable USB debugging
3. Now connect to your PC, now a pop up on the device (not on PC) will ask you for authenticating the PC, Thats it...

adb devices now lists both device id and no offline.

This isn't something to configure in node.js at all, this is purely OS responsibility (Windows in your case). The most reliable way to achieve this is through a Windows Service.

There's this super easy module that installs a node script as a windows service, it's called node-windows (npm, github, documentation). I've used before and worked like a charm.

var Service = require('node-windows').Service;

// Create a new service object
var svc = new Service({
  name:'Hello World',
  description: 'The nodejs.org example web server.',
  script: 'C:\\path\\to\\helloworld.js'
});

// Listen for the "install" event, which indicates the
// process is available as a service.
svc.on('install',function(){
  svc.start();
});

svc.install();

p.s.

I found the thing so useful that I built an even easier to use wrapper around it (npm, github).

Installing it:

npm install -g qckwinsvc

Installing your service:

> qckwinsvc
prompt: Service name: [name for your service]
prompt: Service description: [description for it]
prompt: Node script path: [path of your node script]
Service installed

Uninstalling your service:

> qckwinsvc --uninstall
prompt: Service name: [name of your service]
prompt: Node script path: [path of your node script]
Service stopped
Service uninstalled

var assemblyPath = Assembly.GetExecutingAssembly().CodeBase;

You can use below

mRecyclerview.getChildAt(pos);

You can use the button :

1 - make the text empty

2 - set the background for it

+3 - you can use the selector to more useful and nice button

About the imagebutton you can set the image source and the background the same picture and it must be (*.png) when you do it you can make any design for the button

and for more beauty button use the selector //just Google it ;)

You can't. CSS does not support "events". Dare I ask what you need it for? Check out this post here on SO. I can't think of a reason why you would want to hook up an event to a style change. I'm assuming here that the style change is triggered somwhere else by a piece of javascript. Why not add extra logic there?

def func(*args): 
    pass

When you define a function this way, *args will be array of arguments passed to the function. This allows your function to work without knowing ahead of time how many arguments are going to be passed to it.

You do this with keyword arguments too, using **kwargs:

def func2(**kwargs): 
    pass

See: Arbitrary argument lists

In your case, you've defined a class which is acting like a dictionary. The dict.pop method is defined as pop(key[, default]).

Your method doesn't use the default parameter. But, by defining your method with *args and passing *args to dict.pop(), you are allowing the caller to use the default parameter.

In other words, you should be able to use your class's pop method like dict.pop:

my_a = a()
value1 = my_a.pop('key1')       # throw an exception if key1 isn't in the dict
value2 = my_a.pop('key2', None) # return None if key2 isn't in the dict

If you are using springboot then jackson is added by default,

So the version of jackson you are adding manualy is probably conflicting with the one spring boot adds,

Try to delete the jackson dependencies from your pom,

If you need to override the version spring boots add, then you need to exclude it first and then add your own

You shouldn't use Exceptions to validate your values.

For single character there is a simple solution:

Character.isDigit()

For longer values it's better to use some utils. NumberUtils provided by Apache would work perfectly here:

NumberUtils.isNumber()

Please check https://commons.apache.org/proper/commons-lang/javadocs/api-2.6/org/apache/commons/lang/math/NumberUtils.html

Just add a new datafile for the existing tablespace

ALTER TABLESPACE LEGAL_DATA ADD DATAFILE '/u01/oradata/userdata03.dbf' SIZE 200M;

To find out the location and size of your data files:

SELECT FILE_NAME, BYTES FROM DBA_DATA_FILES WHERE TABLESPACE_NAME = 'LEGAL_DATA';

For Windows check the StackWalk64() API (also on 32bit Windows). For UNIX you should use the OS' native way to do it, or fallback to glibc's backtrace(), if availabe.

Note however that taking a Stacktrace in native code is rarely a good idea - not because it is not possible, but because you're usally trying to achieve the wrong thing.

Most of the time people try to get a stacktrace in, say, an exceptional circumstance, like when an exception is caught, an assert fails or - worst and most wrong of them all - when you get a fatal "exception" or signal like a segmentation violation.

Considering the last issue, most of the APIs will require you to explicitly allocate memory or may do it internally. Doing so in the fragile state in which your program may be currently in, may acutally make things even worse. For example, the crash report (or coredump) will not reflect the actual cause of the problem, but your failed attempt to handle it).

I assume you're trying to achive that fatal-error-handling thing, as most people seem to try that when it comes to getting a stacktrace. If so, I would rely on the debugger (during development) and letting the process coredump in production (or mini-dump on windows). Together with proper symbol-management, you should have no trouble figuring the causing instruction post-mortem.

Try with enabling the sub-thread as daemon-thread.

For Instance:

Recommended:

from threading import Thread

t = Thread(target=<your-method>)
t.daemon = True  # This thread dies when main thread (only non-daemon thread) exits.
t.start()

Inline:

t = Thread(target=<your-method>, daemon=True).start()

Old API:

t.setDaemon(True)
t.start()

When your main thread terminates ("i.e. when I press Ctrl+C"), other threads will also be killed by the instructions above.

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

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

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

    FIRST_NAME  VARCHAR(50) NOT NULL,   
    LAST_NAME   VARCHAR(50) NOT NULL,   
    CITY    VARCHAR(50) DEFAULT NULL,   
    BADGE_NO    INT DEFAULT NULL
    PRIMARY KEY(STUDENT_ID) 
);

Insert data into STUDENTS table.

Then Add FOREIGN KEY : making BADGE_NO as the foreign key of same STUDENTS table

BEGIN;
CREATE TABLE STUDENTS_new (
    STUDENT_ID  INT NOT NULL,   
    FIRST_NAME  VARCHAR(50) NOT NULL,   
    LAST_NAME   VARCHAR(50) NOT NULL,   
    CITY    VARCHAR(50) DEFAULT NULL,   
    BADGE_NO    INT DEFAULT NULL,
    PRIMARY KEY(STUDENT_ID) ,
    FOREIGN KEY(BADGE_NO) REFERENCES STUDENTS(STUDENT_ID)   
);
INSERT INTO STUDENTS_new SELECT * FROM STUDENTS;
DROP TABLE STUDENTS;
ALTER TABLE STUDENTS_new RENAME TO STUDENTS;
COMMIT;

we can add the foreign key from any other table as well.

In my case I was committing transaction when persist method was used. On changing persist to save method , it got resolved.

There is still another way to do it, which is using a particular NamingStrategy, which can be applied to a class or a property by decorating them with [JSonObject] or [JsonProperty].

There are predefined naming strategies like CamelCaseNamingStrategy, but you can implement your own ones.

The implementation of different naming strategies can be found here: https://github.com/JamesNK/Newtonsoft.Json/tree/master/Src/Newtonsoft.Json/Serialization

Your DateFormat pattern does not match you input date String. You could use

You are probably missing the viewport meta tag in the html head:

 <meta name="viewport" content="width=device-width, initial-scale=1">

Without it the device assumes and sets the viewport to full size.

Use the Microsoft "_countof(array)" Macro. This link to the Microsoft Developer Network explains it and offers an example that demonstrates the difference between "sizeof(array)" and the "_countof(array)" macro.

Microsoft and the "_countof(array)" Macro

While @Eli is quite correct that there usually isn't much of a need to do it, it is possible. savefig takes a bbox_inches argument that can be used to selectively save only a portion of a figure to an image.

Here's a quick example:

import matplotlib.pyplot as plt
import matplotlib as mpl
import numpy as np

# Make an example plot with two subplots...
fig = plt.figure()
ax1 = fig.add_subplot(2,1,1)
ax1.plot(range(10), 'b-')

ax2 = fig.add_subplot(2,1,2)
ax2.plot(range(20), 'r^')

# Save the full figure...
fig.savefig('full_figure.png')

# Save just the portion _inside_ the second axis's boundaries
extent = ax2.get_window_extent().transformed(fig.dpi_scale_trans.inverted())
fig.savefig('ax2_figure.png', bbox_inches=extent)

# Pad the saved area by 10% in the x-direction and 20% in the y-direction
fig.savefig('ax2_figure_expanded.png', bbox_inches=extent.expanded(1.1, 1.2))

The full figure:

Area inside the second subplot:

Area around the second subplot padded by 10% in the x-direction and 20% in the y-direction:

Step 1) Make sure postgress is installed in your system ( If it's already installed and you can run postgress server on your machine move to step (2)

apt-get install postgresql postgresql-contrib (sol - fatal error: libpq-fe.h: No such file or directory)
sudo apt-get install ruby-dev (required to install postgress below)
sudo gem install pg
sudo service postgresql restart

Step 2) Some of the c++ files are trying to access libpq-fe.h directly and cant find. So we need to manually search every such file and replace libpq-fe.h with postgresql/libpq-fe.h

Command for searching all occurrences of libpq-fe.h in all dir and subdir is grep -rnw ./ -e 'libpq-fe.h'

3) Go to All the file listed by command run in step 2 and manually change libpq-fe.h with postgresql/libpq-fe.h.

Android has always had the Uri class as part of the SDK: http://developer.android.com/reference/android/net/Uri.html

You can simply do something like:

String requestURL = String.format("http://www.example.com/?a=%s&b=%s", Uri.encode("foo bar"), Uri.encode("100% fubar'd"));

A scanner breaks its input into tokens using a delimiter pattern, which is by default known the Whitespaces.

Next() uses to read a single word and when it gets a white space,it stops reading and the cursor back to its original position. NextLine() while this one reads a whole word even when it meets a whitespace.the cursor stops when it finished reading and cursor backs to the end of the line. so u don't need to use a delimeter when you want to read a full word as a sentence.you just need to use NextLine().

 public static void main(String[] args) {
            // TODO code application logic here
           String str;
            Scanner input = new Scanner( System.in );
            str=input.nextLine();
            System.out.println(str);
       }

1) Use it to ensure an ordered execution of callbacks:

var step1 = new Deferred();
var step2 = new Deferred().done(function() { return step1 });
var step3 = new Deferred().done(function() { return step2 });

step1.done(function() { alert("Step 1") });
step2.done(function() { alert("Step 2") });
step3.done(function() { alert("All done") });
//now the 3 alerts will also be fired in order of 1,2,3
//no matter which Deferred gets resolved first.

step2.resolve();
step3.resolve();
step1.resolve();

2) Use it to verify the status of the app:

var loggedIn = logUserInNow(); //deferred
var databaseReady = openDatabaseNow(); //deferred

jQuery.when(loggedIn, databaseReady).then(function() {
  //do something
});

tl;dr

Month                             // Enum class, predefining and naming a dozen objects, one for each month of the year. 
.of( 12 )                         // Retrieving one of the enum objects by number, 1-12. 
.getDisplayName(
    TextStyle.FULL_STANDALONE , 
    Locale.CANADA_FRENCH          // Locale determines the human language and cultural norms used in localizing. 
)

java.time

Since Java 1.8 (or 1.7 & 1.6 with the ThreeTen-Backport) you can use this:

Month.of(integerMonth).getDisplayName(TextStyle.FULL_STANDALONE, locale);

Note that integerMonth is 1-based, i.e. 1 is for January. Range is always from 1 to 12 for January-December (i.e. Gregorian calendar only).

A simple algorithm that gives you random numbers without duplicates can be found in the book Programming Pearls p. 127.

Attention: The resulting array contains the numbers in order! If you want them in random order, you have to shuffle the array, either with Fisher–Yates shuffle or by using a List and call Collections.shuffle().

The benefit of this algorithm is that you do not need to create an array with all the possible numbers and the runtime complexity is still linear O(n).

public static int[] sampleRandomNumbersWithoutRepetition(int start, int end, int count) {
    Random rng = new Random();

    int[] result = new int[count];
    int cur = 0;
    int remaining = end - start;
    for (int i = start; i < end && count > 0; i++) {
        double probability = rng.nextDouble();
        if (probability < ((double) count) / (double) remaining) {
            count--;
            result[cur++] = i;
        }
        remaining--;
    }
    return result;
}

Try this formula:

=SUBSTITUTE(TEXT(A1/B1,"?/?"),"/",":")

Result:

A   B   C
33  11  3:1
25  5   5:1
6   4   3:2

Explanation:

• TEXT(A1/B1,"?/?") turns A/B into an improper fraction
• SUBSTITUTE(...) replaces the "/" in the fraction with a colon

This doesn't require any special toolkits or macros. The only downside might be that the result is considered text--not a number--so you can easily use it for further calculations.

Note: as @Robin Day suggested, increase the number of question marks (?) as desired to reduce rounding (thanks Robin!).

I would say that you should put styles that won't change into a regular style attribute, and conditional/scope styles into an ng-style attribute. Also, string keys are not necessary. For hyphen-delimited CSS keys, use camelcase.

<div ng-style="{backgroundColor: data.backgroundCol}" style="width:20px; height:20px; margin-top:10px; border:solid 1px black;"></div>

This is what worked for me in every datePicker version, firstly converting date into internal datePicker date format, and then converting it back to desired one

var date = "2017-11-07";   
date = $.datepicker.formatDate("dd.mm.yy", $.datepicker.parseDate('yy-mm-dd', date));
// 07.11.2017

Try this:

var thumbnailHold;

    $(".image_thumb").mousedown(function() {
        thumbnailHold = setTimeout(function(){
             checkboxOn(); // Your action Here

         } , 1000);
     return false;
});

$(".image_thumb").mouseup(function() {
    clearTimeout(thumbnailHold);
});

If you're working with .net core, you can use the dotnet CLI, for instance

dotnet add package <package name>

Setting autoScroll to true did not the trick for me, so I did choose another solution. I built a service that hooks in every time the route changes and that uses the built-in $anchorScroll service to scroll to top. Works for me :-).

Service:

 (function() {
    "use strict";

    angular
        .module("mymodule")
        .factory("pageSwitch", pageSwitch);

    pageSwitch.$inject = ["$rootScope", "$anchorScroll"];

    function pageSwitch($rootScope, $anchorScroll) {
        var registerListener = _.once(function() {
            $rootScope.$on("$locationChangeSuccess", scrollToTop);
        });

        return {
            registerListener: registerListener
        };

        function scrollToTop() {
            $anchorScroll();
        }
    }
}());

Registration:

angular.module("mymodule").run(["pageSwitch", function (pageSwitch) {
    pageSwitch.registerListener();
}]);

You can design a lowpass Butterworth filter in runtime, using butter() function, and then apply that to the signal.

fc = 300; % Cut off frequency
fs = 1000; % Sampling rate

[b,a] = butter(6,fc/(fs/2)); % Butterworth filter of order 6
x = filter(b,a,signal); % Will be the filtered signal

Highpass and bandpass filters are also possible with this method. See https://www.mathworks.com/help/signal/ref/butter.html

On Windows and Linux, it's AltShiftA, as RichieHindle pointed out. On OSX it's OptionCommandA (??A). It's also worth noting that the two modes can have different font preferences, so if you've changed the default text font, it can be jarring to toggle block selection modes and see the font change.

Finally, the "search commands" (Ctrl3 or Command3) pop-up will find it for you if you type block. This is useful if you use the feature just frequently enough to forget the hotkey.

You have to implement KeyListener,take a look here: http://docs.oracle.com/javase/7/docs/api/java/awt/event/KeyListener.html

I use a very old java. Jdk 1.4.08 and I had the same issue. The Node class for me did not had the getTextContent() method. I had to use Node.getFirstChild().getNodeValue() instead of Node.getNodeValue() to get the value of the node. This fixed for me.

Obviously tools are easier, but I feel cool doing this in powershell:)

This script finds all the .csproj references in the .sln file, and then within each csproj file it locates files included for compilation. For each file that is included for compilation it creates an object with properties: Solution, Project, File, Lines. It stores all these objects in a list, and then groups and projects the data as needed.

#path to the solution file e.g. "D:\Code\Test.sln"
$slnFile = "D:\Code\Test.sln"


#results
$results = @()

#iterate through .csproj references in solution file
foreach($projLines in get-item $slnFile | Get-Content | Select-String '".*csproj')
{
    $projFile = [System.IO.Path]::Combine([System.IO.Path]::GetDirectoryName($slnFile), [regex]::Match($projLines,'[^"]*csproj').Value)
    $projFolder = [System.IO.Path]::GetDirectoryName($projFile)

    #from csproj file: get lines for files to compile <Compile Include="..."/>
    $includeLines = get-item $projFile | Get-Content | Select-String '<Compile Include'


    #count of all files lines in project
    $linesInProject = 0;
    foreach($fileLine in $includeLines)
    {
        $includedFilePath = [System.IO.Path]::Combine($projFolder, [Regex]::Match($fileLine, '"(?<file>.*)"').Groups["file"].Value)
        $lineCountInFile = (Get-Content $includedFilePath).Count      
        $results+=New-Object PSObject -Property @{ Solution=$slnFile ;Project=$projFile; File=$includedFilePath; Lines=$lineCountInFile }
    }
}

#filter out any files we dont need
$results = $results | ?{!($_.File -match "Designer")}


#print out:

"---------------lines per solution--------------"
$results | group Solution | %{$_.Name + ": " + ($_.Group | Measure-Object Lines -Sum).Sum}
"---------------lines per peoject--------------"
$results | group Project | %{$_.Name + ": " + ($_.Group | Measure-Object Lines -Sum).Sum}

For me the problem was that I installed Java sdk 1.9 before installing eclipse. deleting it and installing Java sdk 1.8 instead fixed it. Also, if you are using mac, try

export JAVA_HOME=$(/usr/libexec/java_home)

and then

echo $JAVA_HOME

your should get something like

/Library/Java/JavaVirtualMachines/jdk1.8.0_144.jdk/Contents/Home

In a Object Relational Mapping context, every object needs to have a unique identifier. You use the @Id annotation to specify the primary key of an entity.

The @GeneratedValue annotation is used to specify how the primary key should be generated. In your example you are using an Identity strategy which

Indicates that the persistence provider must assign primary keys for the entity using a database identity column.

There are other strategies, you can see more here.

a = ['it']
b = ['was']
c = ['annoying']

a.extend(b)
a.extend(c)

# a now equals ['it', 'was', 'annoying']

Use the Database menu and "Set Datasource Location" menu option to change the name or location of each table in a report.

This works for changing the location of a database, changing to a new database, and changing the location or name of an individual table being used in your report.

To change the datasource connection, go the Database menu and click Set Datasource Location.

1. Change the Datasource Connection:
   1. From the Current Data Source list (the top box), click once on the datasource connection that you want to change.
   2. In the Replace with list (the bottom box), click once on the new datasource connection.
   3. Click Update.
2. Change Individual Tables:
   4. From the Current Data Source list (the top box), expand the datasource connection that you want to change.
   5. Find the table for which you want to update the location or name.
   6. In the Replace with list (the bottom box), expand the new datasource connection.
   7. Find the new table you want to update to point to.
   8. Click Update.
   9. Note that if the table name has changed, the old table name will still appear in the Field Explorer even though it is now using the new table. (You can confirm this be looking at the Table Name of the table's properties in Current Data Source in Set Datasource Location. Screenshot http://i.imgur.com/gzGYVTZ.png) It's possible to rename the old table name to the new name from the context menu in Database Expert -> Selected Tables.
3. Change Subreports:
   9. Repeat each of the above steps for any subreports you might have embedded in your report.
   10. Close the Set Datasource Location window.
4. Any Commands or SQL Expressions:
   11. Go to the Database menu and click Database Expert.
   12. If the report designer used "Add Command" to write custom SQL it will be shown in the Selected Tables box on the right.
   13. Right click that command and choose "Edit Command".
   14. Check if that SQL is specifying a specific database. If so you might need to change it.
   15. Close the Database Expert window.
   16. In the Field Explorer pane on the right, right click any SQL Expressions.
   17. Check if the SQL Expressions are specifying a specific database. If so you might need to change it also.
   18. Save and close your Formula Editor window when you're done editing.

And try running the report again.

The key is to change the datasource connection first, then any tables you need to update, then the other stuff. The connection won't automatically change the tables underneath. Those tables are like goslings that've imprinted on the first large goose-like animal they see. They'll continue to bypass all reason and logic and go to where they've always gone unless you specifically manually change them.

To make it more convenient, here's a tip: You can "Show SQL Query" in the Database menu, and you'll see table names qualified with the database (like "Sales"."dbo"."Customers") for any tables that go straight to a specific database. That might make the hunting easier if you have a lot of stuff going on. When I tackled this problem I had to change each and every table to point to the new table in the new database.

(I presume you are aware that using UDP(User Datagram Protocol) does not guarantee delivery, checks for duplicates and congestion control and will just answer your question).

In your server this line:

var data = udpServer.Receive(ref groupEP);

re-assigns groupEP from what you had to a the address you receive something on.

This line:

udpServer.Send(new byte[] { 1 }, 1); 

Will not work since you have not specified who to send the data to. (It works on your client because you called connect which means send will always be sent to the end point you connected to, of course we don't want that on the server as we could have many clients). I would:

UdpClient udpServer = new UdpClient(UDP_LISTEN_PORT);

while (true)
{
    var remoteEP = new IPEndPoint(IPAddress.Any, 11000);
    var data = udpServer.Receive(ref remoteEP);
    udpServer.Send(new byte[] { 1 }, 1, remoteEP); // if data is received reply letting the client know that we got his data          
}

Also if you have server and client on the same machine you should have them on different ports.

There is a RecyclerView subclass named HorizontalGridView you can use it to have horizontal direction. VerticalGridView for vertical direction

Just like normal background-color: #f0f

You just need a way to target it, eg: <option id="myPinkOption">blah</option>

Use concat() function instead of + like this:

select concat(firstname, lastname) as "Name" from test.student

Didn't use eclipse for a while, but there are ATF and Aptana.

Use $_SERVER['REQUEST_METHOD'].

assuming you have a SQL table called mydata - you can load data from a csv file as follows:

COPY MYDATA FROM '<PATH>/MYDATA.CSV' CSV HEADER;

For more details refer to: http://www.postgresql.org/docs/9.2/static/sql-copy.html

(command | tee out.txt; exit ${PIPESTATUS[0]})

Unlike @cODAR's answer this returns the original exit code of the first command and not only 0 for success and 127 for failure. But as @Chaoran pointed out you can just call ${PIPESTATUS[0]}. It is important however that all is put into brackets.

I would recommend at least Eclipse Indigo (v 3.7) for Android Development because even though a minimum of Helios (v 3.6) is required for ADT 22.0.1 as explained here...

... Indigo is required for Android NDK development using CDT, as explained here:

Another option you can do, is the following:

li:before{
    content:'';
    padding: 0 0 0 25px;
    background:url(../includes/images/layouts/featured-list-arrow.png) no-repeat 0 3px;
}

Use (0 3px) to position the list image.

Works in IE8+, Chrome, Firefox, and Opera.

I use this option because you can swap out list-style easily and a good chance you may not even have to use an image at all. (fiddle below)

http://jsfiddle.net/flashminddesign/cYAzV/1/

UPDATE:

This will account for text / content going into the second line:

ul{ 
    list-style-type:none;
}

li{
    position:relative;
}

ul li:before{
    content:'>';
    padding:0 10px 0 0;
    position:absolute;
    top:0; left:-10px;
}

Add padding-left: to the li if you want more space between the bullet and content.

The first one

f = lambda x: x*x
[f(x) for x in range(10)]

runs f() for each value in the range so it does f(x) for each value

the second one

[lambda x: x*x for x in range(10)]

runs the lambda for each value in the list, so it generates all of those functions.

Please read the example in rfc6749 sec 7.1 first.

The bearer token is a type of access token, which does NOT require PoP(proof-of-possession) mechanism.

PoP means kind of multi-factor authentication to make access token more secure. ref

Proof-of-Possession refers to Cryptographic methods that mitigate the risk of Security Tokens being stolen and used by an attacker. In contrast to 'Bearer Tokens', where mere possession of the Security Token allows the attacker to use it, a PoP Security Token cannot be so easily used - the attacker MUST have both the token itself and access to some key associated with the token (which is why they are sometimes referred to 'Holder-of-Key' (HoK) tokens).

Maybe it's not the case, but I would say,

• access token = payment methods
• bearer token = cash
• access token with PoP mechanism = credit card (signature or password will be verified, sometimes need to show your ID to match the name on the card)

BTW, there's a draft of "OAuth 2.0 Proof-of-Possession (PoP) Security Architecture" now.

Several people misread this as a question about how to store passwords in a database. That is wrong. It is about how to store the password that lets you get to the database.

The usual solution is to move the password out of source-code into a configuration file. Then leave administration and securing that configuration file up to your system administrators. That way developers do not need to know anything about the production passwords, and there is no record of the password in your source-control.

jQuery

jQuery makes ridiculously long JavaScript commands like getElementByHerpDerp shorter and cross-browser.

AngularJS

AngularJS allows you to make your own HTML tags/attributes that do things which work well with dynamic web applications (since HTML was designed for static pages).

Edit:

Saying "I have a jQuery background how do I think in AngularJS?" is like saying "I have an HTML background how do I think in JavaScript?" The fact that you're asking the question shows you most likely don't understand the fundamental purposes of these two resources. This is why I chose to answer the question by simply pointing out the fundamental difference rather than going through the list saying "AngularJS makes use of directives whereas jQuery uses CSS selectors to make a jQuery object which does this and that etc....". This question does not require a lengthy answer.

jQuery is a way to make programming JavaScript in the browser easier. Shorter, cross-browser commands, etc.

AngularJS extends HTML, so you don't have to put <div> all over the place just to make an application. It makes HTML actually work for applications rather than what it was designed for, which is static, educational web pages. It accomplishes this in a roundabout way using JavaScript, but fundamentally it is an extension of HTML, not JavaScript.

What about getting the string representation of the lists and comparing them ?

>>> l1 = ['one', 'two', 'three']
>>> l2 = ['one', 'two', 'three']
>>> l3 = ['one', 'three', 'two']
>>> print str(l1) == str(l2)
True
>>> print str(l1) == str(l3)
False

One set of familiar operations that you can do in MapReduce is the set of normal SQL operations: SELECT, SELECT WHERE, GROUP BY, ect.

Another good example is matrix multiply, where you pass one row of M and the entire vector x and compute one element of M * x.

The recent versions of XAMPP for Windows runs PHP 7.x which are NOT compatible with mbcrypt. If you have a package like Laravel that requires mbcrypt, you will need to install an older version of XAMPP. OR, you can run XAMPP with multiple versions of PHP by downloading a PHP package from Windows.PHP.net, installing it in your XAMPP folder, and configuring php.ini and httpd.conf to use the correct version of PHP for your site.

A simple answer in JQuery, I just created this code and thought it will be helpful for others too

    var cont;

    $("div [contenteditable=true]").focus(function() {
        cont=$(this).html();
    });

    $("div [contenteditable=true]").blur(function() {
        if ($(this).html()!=cont) {
           //Here you can write the code to run when the content change
        }           
    });

This is the functional programming method. It lifts the tuple expansion feature out of syntax sugar:

apply_tuple = lambda f, t: f(*t)

Redefine apply_tuple via curry to save a lot of partial calls in the long run:

from toolz import curry
apply_tuple = curry(apply_tuple)

Example usage:

from operator import add, eq
from toolz import thread_last

thread_last(
    [(1,2), (3,4)],
    (map, apply_tuple(add)),
    list,
    (eq, [3, 7])
)

neo4j is:

an embedded, disk-based, fully transactional Java persistence engine that stores data structured in graphs rather than in tables

I haven't had a chance to try it yet - but it looks very promising. Note this is not an SQL database - your object graph is persisted for you - so it might not be appropriate for your existing app.

  .buttonDisabled{
     background-color: unset !important;
    color: unset !important;
}

Use

Intent myIntent = new Intent(v.getContext(), MyClass.class);

or

 Intent myIntent = new Intent(MyFragment.this.getActivity(), MyClass.class);

to start a new Activity. This is because you will need to pass Application or component context as a first parameter to the Intent Constructor when you are creating an Intent for a specific component of your application.

Posting because when I started LINQ + EntityFramework, I stared at these examples for a day.

If you are using EntityFramework, and you have a navigation property named Meta on your Post model object set up, this is dirt easy. If you're using entity and don't have that navigation property, what are you waiting for?

database
  .Posts
  .Where(post => post.ID == id)
  .Select(post => new { post, post.Meta });

If you're doing code first, you'd set up the property thusly:

class Post {
  [Key]
  public int ID {get; set}
  public int MetaID { get; set; }
  public virtual Meta Meta {get; set;}
}

You can also using the Python module Ipython, which in addition to displaying an image in the Spyder console can embed images in Jupyter notebook. In Spyder, the image will be displayed in full size, not scaled to fit the console.

from IPython.display import Image, display
display(Image(filename="mypic.png"))

The answers above did not work for me because in my project, the ngIf is on an input element. I needed access to the nativeElement attribute in order to focus on the input when ngIf is true. There seems to be no nativeElement attribute on ViewContainerRef. Here is what I did (following @ViewChild documentation):

<button (click)='showAsset()'>Add Asset</button>
<div *ngIf='showAssetInput'>
    <input #assetInput />
</div>

...

private assetInputElRef:ElementRef;
@ViewChild('assetInput') set assetInput(elRef: ElementRef) {
    this.assetInputElRef = elRef;
}

...

showAsset() {
    this.showAssetInput = true;
    setTimeout(() => { this.assetInputElRef.nativeElement.focus(); });
}

I used setTimeout before focusing because the ViewChild takes a sec to be assigned. Otherwise it would be undefined.

Do run

npm install 

it will work most of the cases

if your text has newlines, use nl2br php function:

<?php
$string = "foo"."\n"."bar";
echo nl2br($string);
?>

This should look good in browser

It looks like you override public Map<String, String> getHeaders(), defined in Request, to return your desired HTTP headers.

A REGEXP might be more efficient, but you'd have to benchmark it to be sure, e.g.

SELECT * from fiberbox where field REGEXP '1740|1938|1940'; 

One other issue on the Windows platform, make sure you are running your command prompt as an Administrative User!

I don't know how many times this has bitten me...

(I have too low reputation to comment, but this is comment on JoshCaba's entry, using the Ace-engine instead of Jet for Excel 2007)

If you don't have Ace installed/registered on your machine, you can get it at: https://www.microsoft.com/en-US/download/details.aspx?id=13255

It applies for Excel 2010 as well.

If you have multiple versions of a package / module, you need to be using virtualenv (emphasis mine):

virtualenv is a tool to create isolated Python environments.

The basic problem being addressed is one of dependencies and versions, and indirectly permissions. Imagine you have an application that needs version 1 of LibFoo, but another application requires version 2. How can you use both these applications? If you install everything into /usr/lib/python2.7/site-packages (or whatever your platform’s standard location is), it’s easy to end up in a situation where you unintentionally upgrade an application that shouldn’t be upgraded.

Or more generally, what if you want to install an application and leave it be? If an application works, any change in its libraries or the versions of those libraries can break the application.

Also, what if you can’t install packages into the global site-packages directory? For instance, on a shared host.

In all these cases, virtualenv can help you. It creates an environment that has its own installation directories, that doesn’t share libraries with other virtualenv environments (and optionally doesn’t access the globally installed libraries either).

That's why people consider insert(0, to be wrong -- it's an incomplete, stopgap solution to the problem of managing multiple environments.
