I'm using Mojave with rbenv, this solution works for me:

$ vi ~/.bash_profile

Add this line into the file:

if which rbenv > /dev/null; then eval "$(rbenv init -)"; fi

Configure test.ts file inside src folder:

const context = require.context('./', true, /\.spec\.ts$/);

Replace /\.spec\.ts$/ with the file name you want to test. For example: /app.component\.spec\.ts$/

This will run test only for app.component.spec.ts.

You may have to run cmd as administrator to perform these tasks. You can do it by right clicking on cmd icon and selecting run as administrator. It's worked for me.

Can you try enabling Hyper-V manually, and potentially creating and running a Hyper-V VM manually? Details:

• https://msdn.microsoft.com/en-us/virtualization/hyperv_on_windows/quick_start/walkthrough_install

As of Node.js 14.3.0 the top-level await is supported.

Required flag: --experimental-top-level-await.

This error actually also comes when using keras.preprocessing.image so for example:

img = keras.preprocessing.image.load_img(folder_path, target_size=image_size)

will throw the permission error. Strangely enough though, the problem is solved if you first import the library: from keras.preprocessing import image and only then use it. Like so:

img = image.load_img(img_path, target_size=(180,180))

1. pod init
2. close current xcode project
3. reopen xcode project with the xcworkspace suffix

Buying a new processor is one solution, but for some of us that means buying other components as well. Alternatively you could just buy an Android phone that supports your lowest target API level and run your apps off the phone. You can find some of those phones on Amazon, Ebay, craigslist for pennies (sometimes). Plus this grants you the benefit of actually running on the minimum hardware you intend to support. While this may be a bit slower than installing your app on an emulated system, it will probably save you money.

Android, device testing/debugging link: http://developer.android.com/tools/device.html

A component cannot update its own props unless they are arrays or objects (having a component update its own props even if possible is an anti-pattern), but can update its state and the props of its children.

For instance, a Dashboard has a speed field in its state, and passes it to a Gauge child thats displays this speed. Its render method is just return <Gauge speed={this.state.speed} />. When the Dashboard calls this.setState({speed: this.state.speed + 1}), the Gauge is re-rendered with the new value for speed.

Just before this happens, Gauge's componentWillReceiveProps is called, so that the Gauge has a chance to compare the new value to the old one.

Bundler 2

If you need to update from bundler v1 to v2 follow this official guide.

For a fast solution:

1. In root fo your application run bundle config set path "/bundle" to add a custom path for bundler use, in this case I set /bundle, you can use whatever.

   1.2 [Alternative solution] You can use a bundler file (~/.bundle/config) also, to use this I recommend set bundler folders in environment, like a Docker image, for example. Here the official guide.

2. You don't need to delete your Gemfile.lock, It's a bad practice and this can cause other future problems. Commit Gemfile.lock normaly, sometimes you need to update your bundle with bundle install or install individual gem.

You can see all the configs for bundler version 2 here.

In Addition to @Yifei answer. If you have special character like @, &, $

You have to go with percent-encode | encode the special characters. E.g. instead of this:

http://foo:B@[email protected]:80

you write this:

http://foo:B%[email protected]:80

So @ gets replaced with %40.

This probably means that python doesn't know where PyQt5 is located. To check, go into the interactive terminal and type:

import sys
print sys.path

What you probably need to do is add the directory that contains the PyQt5 module to your PYTHONPATH environment variable. If you use bash, here's how:

Type the following into your shell, and add it to the end of the file ~/.bashrc

export PYTHONPATH=/path/to/PyQt5/directory:$PYTHONPATH

where /path/to/PyQt5/directory is the path to the folder where the PyQt5 library is located.

Had an similar issue embeding youtube chat and I figure it out. Maybe there is a similar solution for similar problem.

Refused to display 'https://www.youtube.com/live_chat?v=yDc9BonIXXI&embed_domain=your.domain.web' in a frame because it set 'X-Frame-Options' to 'sameorigin'

My webpage works with www and without it. So to make it work you need to make sure you load the one that is listed on the embed_domain= value... Maybe there is a variable your missing to tell where to embed your iframe. To fix my problem had to write a script to detect the right webpage and execute proper iframe embed domain name.

<iframe src='https://www.youtube.com/live_chat?v=yDc9BonIXXI&embed_domain=your.domain.web' width="100%" height="600" frameborder='no' scrolling='no'></iframe>

or

<iframe src='https://www.youtube.com/live_chat?v=yDc9BonIXXI&embed_domain=www.your.domain.web' width="100%" height="600" frameborder='no' scrolling='no'></iframe>

Understand you are not using iframes, but still there may be some variable you need to add to your syntax to tell it where the script is going to be used.

To extend further this topic. In case you want to add Font Awesome 5 icons you need to add some extra CSS.

Icons by default have classes svg-inline--fa and fa-w-*.

There are also modifier classes like fa-lg, fa-rotate-* and other. You need to check svg-with-js.css file and find proper CSS for that.

You need to add your own color to css icon otherwise it will be black by default, for example fill='%23f00' where %23 is encoded #.

You most likely have more than one Ruby installed.

If you are using RVM, you probably need to run:

rvm use system

to set the version of ruby to use.

See http://rvm.io/rubies/default

ruby -v

will tell you the version you are currently using.

Alongside nmaier's answer, as he said you'll always receive code 1006. However, if you were to somehow theoretically receive other codes, here is code to display the results (via RFC6455).

you will almost never get these codes in practice so this code is pretty much pointless

gem bootstrap-sass

bootstrap-sass is easy to drop into Rails with the asset pipeline.

In your Gemfile you need to add the bootstrap-sass gem, and ensure that the sass-rails gem is present - it is added to new Rails applications by default.

gem 'sass-rails', '>= 3.2' # sass-rails needs to be higher than 3.2 gem 'bootstrap-sass', '~> 3.0.3.0'

bundle install and restart your server to make the files available through the pipeline.

Source: http://rubydoc.info/gems/bootstrap-sass/3.0.3.0/frames

I faced this same issue on CentOS 7 years later

Posting hoping that it may help others...

Steps:

FIRST, configure the php-fpm settings:

-> systemctl stop php-fpm.service

-> cd /etc/php-fpm.d

-> ls -hal (should see a www.conf file)

-> cp www.conf www.conf.backup (back file up just in case)

-> vi www.conf

-> :/listen = (to get to the line we need to change)

-> i (to enter VI's text insertion mode)

-> change from listen = 127.0.0.1:9000 TO listen = /var/run/php-fpm/php-fpm.sock

-> Esc then :/listen.owner (to find it) then i (to change)

-> UNCOMMENT the listen.owner = nobody AND listen.group = nobody lines

-> Hit Esc then type :/user = then i

-> change user = apache TO user = nginx

-> AND change group = apache TO group = nginx

-> Hit Esc then :wq (to save and quit)

-> systemctl start php-fpm.service (now you will have a php-fpm.sock file)

SECOND, you configure your server {} block in your /etc/nginx/nginx.conf file. Then run:systemctl restart nginx.service

FINALLY, create a new .php file in your /usr/share/nginx/html directory for your Nginx server to serve up via the internet browser as a test.

-> vi /usr/share/nginx/html/mytest.php

-> type o

-> <?php echo date("Y/m/d-l"); ?> (PHP page will print date and day in browser)

-> Hit Esc

-> type :wq (to save and quite VI editor)

-> open up a browser and go to: http://yourDomainOrIPAddress/mytest.php (you should see the date and day printed)

This fixed the issue:

1. Just go to ~/.Genymobile/Genymotion/ova (Either you are on Mac OSX or Windows, you can find this path by looking for Virtualbox path at the Genymotion Settings, there is a path to Genymotion/deployed folder, you should go to Genymotion/ova folder)
2. Open the ova file with your virtualbox.
3. At the Virtualbox startup dialog box, Appliance settings, It shows Guest OS type set to Other Linux 64, you should double click and change it to your OS type (e.g Mac OSX El Captain (64-bit)) and Import:
4. Now launch Genymotion and find the virtual device in the list of already deployed ones ready to run
5. Run the virtual device, after first run you get a warning saying Genymotion version does not match with Virtualbox version and choose Continue.

I hope it helps future visitors to this page.

You can easily install it using Anaconda. At first install Anaconda or Miniconda on you system (download from here) and then install the pyqt as follow:

conda install pyqt

It works for both version of python (2 and 3).

4.19.4 The instanceof operator

The instanceof operator requires the left operand to be of type Any, an object type, or a type parameter type, and the right operand to be of type Any or a subtype of the 'Function' interface type. The result is always of the Boolean primitive type.

So you could use

mySprite instanceof Sprite;

Note that this operator is also in ActionScript but it shouldn't be used there anymore:

The is operator, which is new for ActionScript 3.0, allows you to test whether a variable or expression is a member of a given data type. In previous versions of ActionScript, the instanceof operator provided this functionality, but in ActionScript 3.0 the instanceof operator should not be used to test for data type membership. The is operator should be used instead of the instanceof operator for manual type checking, because the expression x instanceof y merely checks the prototype chain of x for the existence of y (and in ActionScript 3.0, the prototype chain does not provide a complete picture of the inheritance hierarchy).

TypeScript's instanceof shares the same problems. As it is a language which is still in its development I recommend you to state a proposal of such facility.

• MDN: instanceof

If for a block cipher you're not going to use a Cipher transformation that includes a padding scheme, you need to have the number of bytes in the plaintext be an integral multiple of the block size of the cipher.

So either pad out your plaintext to a multiple of 16 bytes (which is the AES block size), or specify a padding scheme when you create your Cipher objects. For example, you could use:

Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5Padding");

Unless you have a good reason not to, use a padding scheme that's already part of the JCE implementation. They've thought out a number of subtleties and corner cases you'll have to realize and deal with on your own otherwise.

Ok, your second problem is that you are using String to hold the ciphertext.

In general,

String s = new String(someBytes);
byte[] retrievedBytes = s.getBytes();

will not have someBytes and retrievedBytes being identical.

If you want/have to hold the ciphertext in a String, base64-encode the ciphertext bytes first and construct the String from the base64-encoded bytes. Then when you decrypt you'll getBytes() to get the base64-encoded bytes out of the String, then base64-decode them to get the real ciphertext, then decrypt that.

The reason for this problem is that most (all?) character encodings are not capable of mapping arbitrary bytes to valid characters. So when you create your String from the ciphertext, the String constructor (which applies a character encoding to turn the bytes into characters) essentially has to throw away some of the bytes because it can make no sense of them. Thus, when you get bytes out of the string, they are not the same bytes you put into the string.

In Java (and in modern programming in general), you cannot assume that one character = one byte, unless you know absolutely you're dealing with ASCII. This is why you need to use base64 (or something like it) if you want to build strings from arbitrary bytes.

This is assuming a Conda Environment. At a high level, what worked for me was simply configuring my Conda path in Spyder. Here is how I did it:

First, determine the path your env exists at

1. Create your environment

2. In the Anaconda navigator, click to "environments" and then hit the play button on the environment you want to open.

3. Click "Open with Python," you should get an interactive Python shell

4. Type "import numpy" (choose any package)

5. Type "numpy" and take a look at the path that looks like this:

C:\\Users\My Name\\.conda\\envs\\pytorch-three\\lib\\site-packages\\numpy\\__init__.py

The important part is the path all the way down to site-packages

For Spyder to be able to read your packages, do the following within Spyder.

1. Open Spyder from anywhere

2. Click "tools" and "preferences"

3. In your Python Interpreter click "Use the following Python interpreter"

4. From the path above, navigate to your environment and select the Python executable. For me it was here: C:\\Users\My Name\\.conda\\envs\\pytorch-three\\python.exe

5. Finally, add the C:\\Users\\My Name\\.conda\\envs\\pytorch-three\\libs\\site-libs folder to the path (which will exist in your environment). This is easily done through the little Python icon with the tooltip of "add to path"

I personally didn't need to restart my IDE, but you may need to.

It's called market segmentation or something like that. nVidia produces one very configurable chip and then sells it in different configurations that essentially have the same elements and hence the same bill of materials to different market segments, although one would usually expect to find elements of higher quality on the more expensive Quadro boards.

What differentiates Quadro from GeForce is that GeForce usually has its dual precision floating point performance severely limited, e.g. to 1/4 or 1/8 of that of the Quadro/Tesla GPUs. This limitation is purely artificial and imposed on solely to differentiate the gamer/enthusiast segment from the professional segment. Lower DP performance makes GeForce boards bad candidates for stuff like scientific or engineering computing and those are markets where money streams from. Also Quadros (arguably) have more display channels and faster RAMDACs which allows them to drive more and higher resolution screens, a sort of setup perceived as professional for CAD/CAM work.

As Jason Morgan has pointed out, there are tricks that can unlock some of the disabled features in GeForce to bring them in par with Quadro. Those usually involves soldering and voids the warranty on the card. Since HPC puts lots of stress on the hardware and malfunctions occur more frequently that one would like them to, I would advise against using cheap tricks.

if you get this issue while running certbot while creating or renewing certificate, Please use the following method

grep -r -P '[^\x00-\x7f]' /etc/apache2 /etc/letsencrypt /etc/nginx

That command found the offending character "´" in one .conf file in the comment. After removing it (you can edit comments as you wish) and reloading nginx, everything worked again.

Ensures the path to Xcode.app bundle is without space or strange characters. I have Xcode installed in ~/Downloads/Last Dev Tools/ folder, so with spaces and renaming the folder to LastDevTools fixed this (after resetting xcode-select -p though)

For what it is worth I came to this page because I had the same problem. I never got anywhere except some IMAP stuff that I don't understand. Then I remembered I had uninstalled privoxy on my ubuntu (because of some weird runtime error that mentioned 127.0.0.1:8118 when I used Daniel Kehoe's Rails template, https://github.com/RailsApps/rails3-application-templates [never discovered what it was]) and I hadn't changed my terminal to the state of no system wide proxy, under network proxy.

I know this may not be on-point but if I wound up here maybe other privoxy users can benefit too.

In the new Jenkins 2.0 pipeline (previously named the Workflow Plugin), this is done differently for:

• The main repository
• Other additional repositories

Here I am specifically referring to the Multibranch Pipeline version 2.9.

Main repository

This is the repository that contains your Jenkinsfile.

In the Configure screen for your pipeline project, enter your repository name, etc.

Do not use Additional Behaviors > Check out to a sub-directory. This will put your Jenkinsfile in the sub-directory where Jenkins cannot find it.

In Jenkinsfile, check out the main repository in the subdirectory using dir():

dir('subDir') {
    checkout scm
}

Additional repositories

If you want to check out more repositories, use the Pipeline Syntax generator to automatically generate a Groovy code snippet.

In the Configure screen for your pipeline project:

1. Select Pipeline Syntax. In the Sample Step drop down menu, choose checkout: General SCM.
2. Select your SCM system, such as Git. Fill in the usual information about your repository or depot.
3. Note that in the Multibranch Pipeline, environment variable env.BRANCH_NAME contains the branch name of the main repository.
4. In the Additional Behaviors drop down menu, select Check out to a sub-directory
5. Click Generate Groovy. Jenkins will display the Groovy code snippet corresponding to the SCM checkout that you specified.
6. Copy this code into your pipeline script or Jenkinsfile.

Append ll suffix to hex digits for 64-bit (long long int), or ull suffix for unsigned 64-bit (unsigned long long)

In windows environment, use

%I64d

in Linux, use

%lld

The way I handled this was switching the className of a label based on a condition. This way you only need one label and you can have different classes for different states... Hope that helps!

You can find more about it in the bundler website (emphasis added below for your convenience):

After developing your application for a while, check in the application together with the Gemfile and Gemfile.lock snapshot. Now, your repository has a record of the exact versions of all of the gems that you used the last time you know for sure that the application worked...

This is important: the Gemfile.lock makes your application a single package of both your own code and the third-party code it ran the last time you know for sure that everything worked. Specifying exact versions of the third-party code you depend on in your Gemfile would not provide the same guarantee, because gems usually declare a range of versions for their dependencies.

The solution for us was the opposite. We disabled hardware acceleration on the WebView only (rather than on the entire app in the manifest) by using this code:

if (Build.VERSION.SDK_INT >= 11){
    webview.setLayerType(View.LAYER_TYPE_SOFTWARE, null);
}

CSS3 animations are smoother now. We are using Android 4.0.

If you're using rbenv running rbenv rehash can solve this after you've installed bundler and are still getting the issue.

As i tried all above as my friends said but nothing worked actually, I was facing same problem and found solution in some different way my issue starts when i added below repository

<dependency>
  <groupId>dom4j</groupId>
  <artifactId>dom4j</artifactId>
  <version>20040902.021138</version>
</dependency>

and my problem starts...so then i changed the version and took previous version and it removed all error. So i think this issue can because of the version we are adding in POM.xml file.

Sorry, now I've read what you expected better, so I'm updating the answer.

Based on the HTML5 Specs from W3C, nothing is wrong. I created this JSFiddle test and it's behaving correctly based on the specs (for those browsers based on the specs, like Chrome 11 and Firefox 4):

<form>_x000D_
    <input type="checkbox" name="q" id="a-0" required autofocus>_x000D_
    <label for="a-0">a-1</label>_x000D_
    <br>_x000D_
_x000D_
    <input type="checkbox" name="q" id="a-1" required>_x000D_
    <label for="a-1">a-2</label>_x000D_
    <br>_x000D_
_x000D_
    <input type="checkbox" name="q" id="a-2" required>_x000D_
    <label for="a-2">a-3</label>_x000D_
    <br>_x000D_
_x000D_
    <input type="submit">_x000D_
</form>

I agree that it isn't very usable (in fact many people have complained about it in the W3C's mailing lists).

But browsers are just following the standard's recommendations, which is correct. The standard is a little misleading, but we can't do anything about it in practice. You can always use JavaScript for form validation, though, like some great jQuery validation plugin.

Another approach would be choosing a polyfill that can make (almost) all browsers interpret form validation rightly.

Your original plan sounds fine to me. You'll probably find more browser quirks dealing with dynamically managing the <source> elements, as indicated here by the W3 spec note:

Dynamically modifying a source element and its attribute when the element is already inserted in a video or audio element will have no effect. To change what is playing, just use the src attribute on the media element directly, possibly making use of the canPlayType() method to pick from amongst available resources. Generally, manipulating source elements manually after the document has been parsed is an unncessarily[sic] complicated approach.

• LG Optimus 2x (P990)
• LG Optimus Black (P970)
• LG Optimus 3D (P920)
• Samsung Galaxy S II (i9100)
• Samsung Galaxy S III (i9300)

Faced the same problem. Probably it could be a solution:

<select id="select-1">
    <option>One</option>
    <option>Two</option>
    <option>Three</option>
</select>
<label for="select-1"></label>

#select-1 {
    ...
}

#select-1 + label:after {
    ...
}

Edit:

As written in the comments the old code is not "best practice". You should use a keygeneration algorithm like PBKDF2 with a high iteration count. You also should use at least partly a non static (meaning for each "identity" exclusive) salt. If possible randomly generated and stored together with the ciphertext.

    SecureRandom sr = SecureRandom.getInstanceStrong();
    byte[] salt = new byte[16];
    sr.nextBytes(salt);

    PBEKeySpec spec = new PBEKeySpec(password.toCharArray(), salt, 1000, 128 * 8);
    SecretKey key = SecretKeyFactory.getInstance("PBKDF2WithHmacSHA1").generateSecret(spec);
    Cipher aes = Cipher.getInstance("AES");
    aes.init(Cipher.ENCRYPT_MODE, key);

===========

Old Answer

You should use SHA-1 to generate a hash from your key and trim the result to 128 bit (16 bytes).

Additionally don't generate byte arrays from Strings through getBytes() it uses the platform default Charset. So the password "blaöä" results in different byte array on different platforms.

byte[] key = (SALT2 + username + password).getBytes("UTF-8");
MessageDigest sha = MessageDigest.getInstance("SHA-1");
key = sha.digest(key);
key = Arrays.copyOf(key, 16); // use only first 128 bit

SecretKeySpec secretKeySpec = new SecretKeySpec(key, "AES");

Edit: If you need 256 bit as key sizes you need to download the "Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files" Oracle download link, use SHA-256 as hash and remove the Arrays.copyOf line. "ECB" is the default Cipher Mode and "PKCS5Padding" the default padding. You could use different Cipher Modes and Padding Modes through the Cipher.getInstance string using following format: "Cipher/Mode/Padding"

For AES using CTS and PKCS5Padding the string is: "AES/CTS/PKCS5Padding"

I believe the 2GB limit is for 32-bit Java. I thought v1.6 was always 64 bit, but try forcing 64 bit mode just to see: add the -d64 option.

The safest command to push different local Git branches to Heroku/master.

git push -f heroku branch_name:master

Note: Although, you can push without using the -f, the -f (force flag) is recommended in order to avoid conflicts with other developers’ pushes.

No. You can't. But it is very possible in Scala:

class Foo {val bar = "a"}
class Bar {val foo = "b"}

The following is the one that I'm using to generate a vertical gradient from completely opaque (top) to 20% in transparency (bottom) for the same color:

background: linear-gradient(to bottom, rgba(0, 64, 122, 1) 0%,rgba(0, 64, 122, 0.8) 100%); /* W3C, IE10+, FF16+, Chrome26+, Opera12+, Safari7+ */
background: -o-linear-gradient(top, rgba(0, 64, 122, 1) 0%, rgba(0, 64, 122, 0.8) 100%); /* Opera 11.10+ */
background: -moz-linear-gradient(top, rgba(0, 64, 122, 1) 0%, rgba(0, 64, 122, 0.8) 100%); /* FF3.6-15 */
background: -webkit-linear-gradient(top, rgba(0, 64, 122, 1) 0%,rgba(0, 64, 122, 0.8) 100%); /* Chrome10-25,Safari5.1-6 */
background: -ms-linear-gradient(top, rgba(0, 64, 122, 1) 0%,rgba(0, 64, 122, 0.8) 100%); /* IE10+ */
-ms-filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#00407a', endColorstr='#cc00407a',GradientType=0 ); /* IE8 */
filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#00407a', endColorstr='#cc00407a',GradientType=0 ); /* IE 5.5 - 9 */

I was also trying to understand ABI and JesperE’s answer was very helpful.

From a very simple perspective, we may try to understand ABI by considering binary compatibility.

KDE wiki defines a library as binary compatible “if a program linked dynamically to a former version of the library continues running with newer versions of the library without the need to recompile.” For more on dynamic linking, refer Static linking vs dynamic linking

Now, let’s try to look at just the most basic aspects needed for a library to be binary compatibility (assuming there are no source code changes to the library):

1. Same/backward compatible instruction set architecture (processor instructions, register file structure, stack organization, memory access types, along with sizes, layout, and alignment of basic data types the processor can directly access)
2. Same calling conventions
3. Same name mangling convention (this might be needed if say a Fortran program needs to call some C++ library function).

Sure, there are many other details but this is mostly what the ABI also covers.

More specifically to answer your question, from the above, we can deduce:

ABI functionality: binary compatibility

existing entities: existing program/libraries/OS

consumer: libraries, OS

Hope this helps!

I've faked readonly on a radio button by disabling only the un-checked radio buttons. It keeps the user from selecting a different value, and the checked value will always post on submit.

Using jQuery to make readonly:

$(':radio:not(:checked)').attr('disabled', true);

This approach also worked for making a select list readonly, except that you'll need to disable each un-selected option.

It might also be worth mentioning that inline will try to open Office Documents (xls, doc etc) directly from the server, which might lead to a User Credentials Prompt.

see this link:

http://forums.asp.net/t/1885657.aspx/1?Access+the+SSRS+Report+in+excel+format+on+server

somebody tried to deliver an Excel Report from SSRS via ASP.Net -> the user always got prompted to enter the credentials. After clicking cancel on the prompt it would be opened anyway...

If the Content Disposition is marked as Attachment it will automatically be saved to the temp folder after clicking open and then opened in Excel from the local copy.

Its boils down to this: math.h is from C and was created over 10 years ago. In math.h, due to its primitive nature, the abs() function is "essentially" just for integer types and if you wanted to get the absolute value of a double, you had to use fabs(). When C++ was created it took math.h and made it cmath. cmath is essentially math.h but improved for C++. It improved things like having to distinguish between fabs() and abs, and just made abs() for both doubles and integer types. In summary either: Use math.h and use abs() for integers, fabs() for doubles or use cmath and just have abs for everything (easier and recommended)

Hope this helps anyone who is having the same problem!

(Maybe helpful for others with a similar requirement)

I had a similar requirement to use AES-256-CBC encrypt and decrypt in Java.

To achieve (or specify) the 256-byte encryption/decryption, Java Cryptography Extension (JCE) policy should set to "Unlimited"

It can be set in the java.security file under $JAVA_HOME/jre/lib/security (for JDK) or $JAVA_HOME/lib/security (for JRE)

crypto.policy=unlimited

Or in the code as

Security.setProperty("crypto.policy", "unlimited");

Java 9 and later versions have this enabled by default.

Yes, you can read the spec a hundred times, and combine different bits and pieces until you have an interpretation that feels right – but that's exactly what the browser vendors did and that's why we're in the situation we are today.

In essence, when you apply a width of 100% to an element it should extend to 100% of it's parent's width, if that parent is a block element. You can't center it anymore with margin: 0 auto; then since it already takes up 100% of the available width.

To center anything with margin: 0 auto; you need to define an explicit width. To center an inline element, you can use text-align: center; on the parent element, although this could have unwanted side-effects if the parent has other children.

From the RFC 4648:

Base encoding of data is used in many situations to store or transfer data in environments that, perhaps for legacy reasons, are restricted to US-ASCII data.

So it depends on the purpose of usage of the encoded data if the data should be considered as dangerous.

But if you’re just looking for a regular expression to match Base64 encoded words, you can use the following:

^(?:[A-Za-z0-9+/]{4})*(?:[A-Za-z0-9+/]{2}==|[A-Za-z0-9+/]{3}=)?$

If the select dropdown is read-only since birth and does not need to change at all, perhaps you should use another control instead? Like a simple <div> (plus hidden form field) or an <input type="text">?

Added: If the dropdown is not read-only all the time and JavaScript is used to enable/disable it, then this is still a solution - just modify the DOM on-the-fly.

I think I showed you this one before, but I like the fun here - this took some debugging to track down! (the original code was obviously more complex and subtle...)

    static void Foo<T>() where T : new()
    {
        T t = new T();
        Console.WriteLine(t.ToString()); // works fine
        Console.WriteLine(t.GetHashCode()); // works fine
        Console.WriteLine(t.Equals(t)); // works fine

        // so it looks like an object and smells like an object...

        // but this throws a NullReferenceException...
        Console.WriteLine(t.GetType());
    }

So what was T...

Answer: any Nullable<T> - such as int?. All the methods are overridden, except GetType() which can't be; so it is cast (boxed) to object (and hence to null) to call object.GetType()... which calls on null ;-p

Update: the plot thickens... Ayende Rahien threw down a similar challenge on his blog, but with a where T : class, new():

private static void Main() {
    CanThisHappen<MyFunnyType>();
}

public static void CanThisHappen<T>() where T : class, new() {
    var instance = new T(); // new() on a ref-type; should be non-null, then
    Debug.Assert(instance != null, "How did we break the CLR?");
}

But it can be defeated! Using the same indirection used by things like remoting; warning - the following is pure evil:

class MyFunnyProxyAttribute : ProxyAttribute {
    public override MarshalByRefObject CreateInstance(Type serverType) {
        return null;
    }
}
[MyFunnyProxy]
class MyFunnyType : ContextBoundObject { }

With this in place, the new() call is redirected to the proxy (MyFunnyProxyAttribute), which returns null. Now go and wash your eyes!

You can also use the actual text of the *e*xample test case with -e !

So for:

it "shows the plane arrival time"

you can use

rspec path/to/spec/file.rb -e 'shows the plane arrival time'
./scripts/spec path/to/spec/file.rb -e 'shows the plane arrival time'

no need for rake here.

You can use the following regular expressions separately or by combining them in a joint OR expression.

ValidIpAddressRegex = "^(([0-9]|[1-9][0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5])\.){3}([0-9]|[1-9][0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5])$";

ValidHostnameRegex = "^(([a-zA-Z0-9]|[a-zA-Z0-9][a-zA-Z0-9\-]*[a-zA-Z0-9])\.)*([A-Za-z0-9]|[A-Za-z0-9][A-Za-z0-9\-]*[A-Za-z0-9])$";

ValidIpAddressRegex matches valid IP addresses and ValidHostnameRegex valid host names. Depending on the language you use \ could have to be escaped with \.

ValidHostnameRegex is valid as per RFC 1123. Originally, RFC 952 specified that hostname segments could not start with a digit.

http://en.wikipedia.org/wiki/Hostname

The original specification of hostnames in RFC 952, mandated that labels could not start with a digit or with a hyphen, and must not end with a hyphen. However, a subsequent specification (RFC 1123) permitted hostname labels to start with digits.

Valid952HostnameRegex = "^(([a-zA-Z]|[a-zA-Z][a-zA-Z0-9\-]*[a-zA-Z0-9])\.)*([A-Za-z]|[A-Za-z][A-Za-z0-9\-]*[A-Za-z0-9])$";

I think the V$SQLAREA table contains what you're looking for (see columns SQL_TEXT and SQL_FULLTEXT).

You can't use placeholders for column names, table names, data type names, or basically anything that isn't data.

I am also working with Laravel and I like the implementation there. I tried to mimic it and combining it with the solution proposed by T. Stone (look above):

PRODUCTION_SERVERS = ['*.webfaction.com','*.whatever.com',]

def check_env():
    for item in PRODUCTION_SERVERS:
        match = re.match(r"(^." + item + "$)", socket.gethostname())
        if match:
            return True

if check_env():
    PRODUCTION = True
else:
    PRODUCTION = False

DEBUG = not PRODUCTION

Maybe something like this would help you.

There's an ongoing effort for a PDCurses port:

Here is another quick approach without using additional panel.

JFrame f = new JFrame("stackoverflow") { 
  private Image backgroundImage = ImageIO.read(new File("background.jpg"));
  public void paint( Graphics g ) { 
    super.paint(g);
    g.drawImage(backgroundImage, 0, 0, null);
  }
};

String hashWith256(String textToHash) {
    MessageDigest digest = MessageDigest.getInstance("SHA-256");
    byte[] byteOfTextToHash = textToHash.getBytes(StandardCharsets.UTF_8);
    byte[] hashedByetArray = digest.digest(byteOfTextToHash);
    String encoded = Base64.getEncoder().encodeToString(hashedByetArray);
    return encoded;
}

If you need this for several words or elements, but can't apply it to a whole TD or similar, the Span tag can be used.

<span style="white-space: nowrap">Text to break together</span>
    or 
<span class=nobr>Text to break together</span>

If you use the class version, remember to set up the CSS as detailed in the accepted answer.

I see this is a fairly old question, but this looks like one of those times when something's been written without knowledge of a language feature. The collections library exists to fulfill these purposes.

from collections import Counter
letter_counter = Counter()
for letter in 'The quick brown fox jumps over the lazy dog':
    letter_counter[letter] += 1

>>> letter_counter

In this example the spaces are being counted, obviously, but whether or not you want those filtered is up to you.

As for the dict.get(a_key, default_value), there have been several answers to this particular question -- this method returns the value of the key, or the default_value you supply. The first argument is the key you're looking for, the second argument is the default for when that key is not present.

ALTER TABLE Table name ADD column datatype AUTO_INCREMENT,ADD primary key(column);

The given answers work if you're in a context where conda is in your PATH environment variable, e.g. if you set it up that way during installation, or if you're running the "Anaconda Prompt".

If that's not the case, e.g. if you're trying to locate conda for use in a script, you should be able to pick up its installation location by probing HKCU\Software\Python for available Python installations. For example:

>for /F "tokens=2,*" %a in ('reg query HKCU\Software\Python /f InstallPath /s /k /ve ^| findstr Default') do @echo %b
C:\Users\<username>\Miniconda3
C:\Users\<username>\Miniconda3

I have managed to solve the problem by following the Chris Slade's answer, but to restart the server, I had to use the following commands:

launchctl unload ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist

launchctl load ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist

that I found here (pjammer's answer down at the bottom)

Using dblink would be more convenient!

truncate table tableA;

insert into tableA
select *
from dblink('hostaddr=xxx.xxx.xxx.xxx dbname=mydb user=postgres',
            'select a,b from tableA')
       as t1(a text,b text);

I just tested this and it works in Access 2010.

Say you have a SELECT query with parameters:

PARAMETERS startID Long, endID Long;
SELECT Members.*
FROM Members
WHERE (((Members.memberID) Between [startID] And [endID]));

You run that query interactively and it prompts you for [startID] and [endID]. That works, so you save that query as [MemberSubset].

Now you create an UPDATE query based on that query:

UPDATE Members SET Members.age = [age]+1
WHERE (((Members.memberID) In (SELECT memberID FROM [MemberSubset])));

You run that query interactively and again you are prompted for [startID] and [endID] and it works well, so you save it as [MemberSubsetUpdate].

You can run [MemberSubsetUpdate] from VBA code by specifying [startID] and [endID] values as parameters to [MemberSubsetUpdate], even though they are actually parameters of [MemberSubset]. Those parameter values "trickle down" to where they are needed, and the query does work without human intervention:

Sub paramTest()
    Dim qdf As DAO.QueryDef
    Set qdf = CurrentDb.QueryDefs("MemberSubsetUpdate")
    qdf!startID = 1  ' specify
    qdf!endID = 2    '     parameters
    qdf.Execute
    Set qdf = Nothing
End Sub

you may try this one, used CONCAT

WHERE LastName LIKE Concat('%',@LastName,'%')

Well, reading it isn't hard, just use FileStream to read a byte[]. Converting it to text isn't really generally possible or meaningful unless you convert the 1's and 0's to hex. That's easy to do with the BitConverter.ToString(byte[]) overload. You'd generally want to dump 16 or 32 bytes in each line. You could use Encoding.ASCII.GetString() to try to convert the bytes to characters. A sample program that does this:

using System;
using System.IO;
using System.Text;

class Program {
    static void Main(string[] args) {
        // Read the file into <bits>
        var fs = new FileStream(@"c:\temp\test.bin", FileMode.Open);
        var len = (int)fs.Length;
        var bits = new byte[len];
        fs.Read(bits, 0, len);
        // Dump 16 bytes per line
        for (int ix = 0; ix < len; ix += 16) {
            var cnt = Math.Min(16, len - ix);
            var line = new byte[cnt];
            Array.Copy(bits, ix, line, 0, cnt);
            // Write address + hex + ascii
            Console.Write("{0:X6}  ", ix);
            Console.Write(BitConverter.ToString(line));
            Console.Write("  ");
            // Convert non-ascii characters to .
            for (int jx = 0; jx < cnt; ++jx)
                if (line[jx] < 0x20 || line[jx] > 0x7f) line[jx] = (byte)'.';
            Console.WriteLine(Encoding.ASCII.GetString(line));
        }
        Console.ReadLine();
    }
}

It seems odd that this method doesn't exist. Is it time to add it finally?

If you wanted to you could something like the following:

var _addEventListener = EventTarget.prototype.addEventListener;
var _removeEventListener = EventTarget.prototype.removeEventListener;
EventTarget.prototype.events = {};
EventTarget.prototype.addEventListener = function(name, listener, etc) {
  var events = EventTarget.prototype.events;
  if (events[name] == null) {
    events[name] = [];
  }

  if (events[name].indexOf(listener) == -1) {
    events[name].push(listener);
  }

  _addEventListener(name, listener);
};
EventTarget.prototype.removeEventListener = function(name, listener) {
  var events = EventTarget.prototype.events;

  if (events[name] != null && events[name].indexOf(listener) != -1) {
    events[name].splice(events[name].indexOf(listener), 1);
  }

  _removeEventListener(name, listener);
};
EventTarget.prototype.hasEventListener = function(name) {
  var events = EventTarget.prototype.events;
  if (events[name] == null) {
    return false;
  }

  return events[name].length;
};

Technically speaking, all of the answers at this time are wrong. packageVersion does not return the version of the loaded package. It goes to the disk, and fetches the package version from there.

This will not make a difference in most cases, but sometimes it does. As far as I can tell, the only way to get the version of a loaded package is the rather hackish:

asNamespace(pkg)$`.__NAMESPACE__.`$spec[["version"]]

where pkg is the package name.

EDIT: I am not sure when this function was added, but you can also use getNamespaceVersion, this is cleaner:

getNamespaceVersion(pkg)

Easiest way I find is to:

1. Right click project

2. Debug as -> Maven build ...

3. In the goals field put -Dmaven.surefire.debug test

4. In the parameters put a new parameter called forkCount with a value of 0 (previously was forkMode=never but it is deprecated and doesn't work anymore)

Set your breakpoints down and run this configuration and it should hit the breakpoint.

Using the syntax text_element.selectionStart we can get the starting position of the selection of a text in terms of the index of the first character of the selected text in the text_element.value and in case we want to get the same of the last character in the selection we have to use text_element.selectionEnd.

Use it as follows:

<input type=text id=t1 value=abcd>
<button onclick="alert(document.getElementById('t1').selectionStart)">check position</button>

Boolean can be very helpful when you need three state. Like in software testing if Test is passed send true , if failed send false and if test case interrupted send null which will denote test case not executed .

I was trying Viachaslau's answer since I like the idea of not removing the button but disabling it, but for some reason it did not always work: the close button was still enabled but no errors whatsoever.

This on the other hand always worked (error checking omitted):

[DllImport( "user32.dll" )]
private static extern IntPtr GetSystemMenu( IntPtr hWnd, bool bRevert );
[DllImport( "user32.dll" )]
private static extern bool EnableMenuItem( IntPtr hMenu, uint uIDEnableItem, uint uEnable );

private const uint MF_BYCOMMAND = 0x00000000;
private const uint MF_GRAYED = 0x00000001;
private const uint SC_CLOSE = 0xF060;
private const int WM_SHOWWINDOW = 0x00000018;

protected override void OnSourceInitialized( EventArgs e )
{
  base.OnSourceInitialized( e );
  var hWnd = new WindowInteropHelper( this );
  var sysMenu = GetSystemMenu( hWnd.Handle, false );
  EnableMenuItem( sysMenu, SC_CLOSE, MF_BYCOMMAND | MF_GRAYED );
}

When getting this error through Visual Studio it was because there was a signing certificate setup to match the computer it was originally developed on.

You can check this by going to the project properties > signing tab and checking the certificate details.

You can uncheck "Sign the ClickOnce manifests" to disable signing.

If you don't want to turn this option off you will have to install the certificate.

So here's what I did eventually. I hope this helps someone else.

class NoDuplicatesList<E> extends LinkedList<E> {
    @Override
    public boolean add(E e) {
        if (this.contains(e)) {
            return false;
        }
        else {
            return super.add(e);
        }
    }

    @Override
    public boolean addAll(Collection<? extends E> collection) {
        Collection<E> copy = new LinkedList<E>(collection);
        copy.removeAll(this);
        return super.addAll(copy);
    }

    @Override
    public boolean addAll(int index, Collection<? extends E> collection) {
        Collection<E> copy = new LinkedList<E>(collection);
        copy.removeAll(this);
        return super.addAll(index, copy);
    }

    @Override
    public void add(int index, E element) {
        if (this.contains(element)) {
            return;
        }
        else {
            super.add(index, element);
        }
    }
}   

Are they identical?

> identical(A,C)
[1] FALSE

Which elements disagree:

> which(A != C)
[1] 2 4

For Swift3/Swift4 Developers:

let radius = yourImageView.frame.width / 2
yourImageView.layer.cornerRadius = radius
yourImageView.layer.masksToBounds = true

In my case I got this message because there's a special char (&) in my connectionstring, remove it then everything's good.

A fundamental mistake is here:

result = methodInfo.Invoke(methodInfo, parametersArray); 

You are invoking the method on an instance of MethodInfo. You need to pass in an instance of the type of object that you want to invoke on.

result = methodInfo.Invoke(classInstance, parametersArray);

don't forget this to add this below in your template:

<router-outlet></router-outlet>

.html always for new files. .htm is a throwback to dos days.

if you are running jdk 8.

public static void print(int[] array) {
    StringJoiner joiner = new StringJoiner(",", "[", "]");
    Arrays.stream(array).forEach(element -> joiner.add(element + ""));
    System.out.println(joiner.toString());
}


int[] array = new int[]{7, 3, 5, 1, 3};
print(array);

output:

[7,3,5,1,3]

Are you sure the address the site is being served up as is the same as the certificate? I had the same problems with Chrome and a self-signed cert, but in the end I found it was just incredibly picky about the validation of the domain name on the cert (as it should be).

Chrome doesn't have it's own cert store and uses Window's own. However Chrome provides no way to import certs into the store so you should add them via IE instead.

Also take a look at this for a couple of different approaches to creating self-signed certs (I'm assuming you're using IIS as you haven't mentioned).

In case you were struggling to change linetypes, the following answer should be helpful. (This is an addition to the solution by Andy W.)

We will try to extend the learned pattern:

cols <- c("LINE1"="#f04546","LINE2"="#3591d1","BAR"="#62c76b")
line_types <- c("LINE1"=1,"LINE2"=3)
ggplot(data=data,aes(x=a)) + 
  geom_bar(stat="identity", aes(y=h,fill = "BAR"))+ #green
  geom_line(aes(y=b,group=1, colour="LINE1", linetype="LINE1"),size=0.5) +   #red
  geom_point(aes(y=b, colour="LINE1", fill="LINE1"),size=2) +           #red
  geom_line(aes(y=c,group=1,colour="LINE2", linetype="LINE2"),size=0.5) +   #blue 
  geom_point(aes(y=c,colour="LINE2", fill="LINE2"),size=2) +           #blue
  scale_colour_manual(name="Error Bars",values=cols, 
                  guide = guide_legend(override.aes=aes(fill=NA))) + 
  scale_linetype_manual(values=line_types)+
  scale_fill_manual(name="Bar",values=cols, guide="none") +
  ylab("Symptom severity") + xlab("PHQ-9 symptoms") +
  ylim(0,1.6) +
  theme_bw() +
  theme(axis.title.x = element_text(size = 15, vjust=-.2)) +
  theme(axis.title.y = element_text(size = 15, vjust=0.3))

However, what we get is the following result:

The problem is that the linetype is not merged in the main legend. Note that we did not give any name to the method scale_linetype_manual. The trick which works here is to give it the same name as what you used for naming scale_colour_manual. More specifically, if we change the corresponding line to the following we get the desired result:

scale_linetype_manual(name="Error Bars",values=line_types)

Now, it is easy to change the size of the line with the same idea.

Note that the geom_bar has not colour property anymore. (I did not try to fix this issue.) Also, adding geom_errorbar with colour attribute spoils the result. It would be great if somebody can come up with a better solution which resolves these two issues as well.

I've modified Foxidrive's answer to copy entire folders and all their contents. this script will create a folder and backup another folder's contents into it, including any subfolders underneath.

If you put this in say an hourly scheduled task you need to be careful as you could fill up your drive quickly with copies of your original folder. Before bitbucket etc i was using as similar script to save my code offline.

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

set stamp=YourPrefixHere_%YYYY%%MM%%DD%@%HH%%Min%
rem you could for example want to create a folder in Gdrive and save backup there
cd C:\YourGoogleDriveFolder
mkdir %stamp%
cd %stamp%

 xcopy C:\FolderWithDataToBackup\*.* /s 

This is simple method to get request data from HttpServletRequest using Java 8 Stream API:

String requestData = request.getReader().lines().collect(Collectors.joining());

Here is a short code snippet for shadowing cin/cout useful for programming contests:

#include <bits/stdc++.h>

using namespace std;

int main() {
    ifstream cin("input.txt");
    ofstream cout("output.txt");

    int a, b;   
    cin >> a >> b;
    cout << a + b << endl;
}

This gives additional benefit that plain fstreams are faster than synced stdio streams. But this works only for the scope of single function.

Global cin/cout redirect can be written as:

#include <bits/stdc++.h>

using namespace std;

void func() {
    int a, b;
    std::cin >> a >> b;
    std::cout << a + b << endl;
}

int main() {
    ifstream cin("input.txt");
    ofstream cout("output.txt");

    // optional performance optimizations    
    ios_base::sync_with_stdio(false);
    std::cin.tie(0);

    std::cin.rdbuf(cin.rdbuf());
    std::cout.rdbuf(cout.rdbuf());

    func();
}

Note that ios_base::sync_with_stdio also resets std::cin.rdbuf. So the order matters.

See also Significance of ios_base::sync_with_stdio(false); cin.tie(NULL);

Std io streams can also be easily shadowed for the scope of single file, which is useful for competitive programming:

#include <bits/stdc++.h>

using std::endl;

std::ifstream cin("input.txt");
std::ofstream cout("output.txt");

int a, b;

void read() {
    cin >> a >> b;
}

void write() {
    cout << a + b << endl;
}

int main() {
    read();
    write();
}

But in this case we have to pick std declarations one by one and avoid using namespace std; as it would give ambiguity error:

error: reference to 'cin' is ambiguous
     cin >> a >> b;
     ^
note: candidates are: 
std::ifstream cin
    ifstream cin("input.txt");
             ^
    In file test.cpp
std::istream std::cin
    extern istream cin;  /// Linked to standard input
                   ^

Some comments were asking how to save all of the IPython inputs at once. For %save magic in IPython, you can save all of the commands programmatically as shown below, to avoid the prompt message and also to avoid specifying the input numbers. currentLine = len(In)-1 %save -f my_session 1-$currentLine

The -f option is used for forcing file replacement and the len(IN)-1 shows the current input prompt in IPython, allowing you to save the whole session programmatically.

DATABASES = {
'default': {
    'ENGINE': 'django.db.backends.mysql',

    'PORT': '3306',
    'OPTIONS': {
        'autocommit': True,
    },
}

}

then:

python manage.py migrate

if success will generate theses tables:

Here is the simplest way to add Gestures on View in Swift 5

import UIKit

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        addGestures()
    }

    // MARK: Add Gestures to target view
    func addGestures()
    {
        // 1. Single Tap or Touch
        let tapGesture = UITapGestureRecognizer(target: self, action: #selector(self.tapGetstureDetected))
        tapGesture.numberOfTapsRequired = 1
        view.addGestureRecognizer(tapGesture)

        //2. Double Tap
        let doubleTapGesture = UITapGestureRecognizer(target: self, action: #selector(self.doubleTapGestureDetected))
        doubleTapGesture.numberOfTapsRequired = 2
        view.addGestureRecognizer(doubleTapGesture)

        //3. Swipe
        let swipeGesture = UISwipeGestureRecognizer(target: self, action: #selector(self.swipeGetstureDetected))
        view.addGestureRecognizer(swipeGesture)

        //4. Pinch
        let pinchGesture = UIPinchGestureRecognizer(target: self, action: #selector(self.pinchGetstureDetected))
        view.addGestureRecognizer(pinchGesture)

        //5. Long Press
        let longPressGesture = UILongPressGestureRecognizer(target: self, action: #selector(self.longPressGetstureDetected))
        view.addGestureRecognizer(longPressGesture)

        //6. Pan
        let panGesture = UILongPressGestureRecognizer(target: self, action: #selector(self.panGestureDetected))
        view.addGestureRecognizer(panGesture)

    }

    // MARK: Handle Gesture detection
    @objc func swipeGetstureDetected() {
        print("Swipe Gesture detected!!")
    }

    @objc func tapGetstureDetected() {
        print("Touch/Tap Gesture detected!!")
    }

    @objc func pinchGetstureDetected() {
        print("Pinch Gesture detected!!")
    }

    @objc func longPressGetstureDetected() {
        print("Long Press Gesture detected!!")
    }

    @objc func doubleTapGestureDetected() {
        print("Double Tap Gesture detected!!")

    @objc func panGestureDetected()
    {
        print("Pan Gesture detected!!")
    }


    //MARK: Shake Gesture
    override func becomeFirstResponder() -> Bool {
        return true
    }
    override func motionEnded(_ motion: UIEvent.EventSubtype, with event: UIEvent?){
        if motion == .motionShake
        {
            print("Shake Gesture Detected")
        }
    }
}

Dedication to LightStriker:
Sample Code:

class CallBackExample
{
    public delegate void MyNumber();
    public static void CallMeBack()
    {
        Console.WriteLine("He/She is calling you.  Pick your phone!:)");
        Console.Read();
    }
    public static void MetYourCrush(MyNumber number)
    {
        int j;
        Console.WriteLine("is she/he interested 0/1?:");
        var i = Console.ReadLine();
        if (int.TryParse(i, out j))
        {
            var interested = (j == 0) ? false : true;
            if (interested)//event
            {
                //call his/her number
                number();
            }
            else
            {
                Console.WriteLine("Nothing happened! :(");
                Console.Read();
            }
        }
    }
    static void Main(string[] args)
    {
        MyNumber number = Program.CallMeBack;
        Console.WriteLine("You have just met your crush and given your number");
        MetYourCrush(number);
        Console.Read();
        Console.Read();
    }       
}

Code Explanation:

I created the code to implement the funny explanation provided by LightStriker in the above one of the replies. We are passing delegate (number) to a method (MetYourCrush). If the Interested (event) occurs in the method (MetYourCrush) then it will call the delegate (number) which was holding the reference of CallMeBack method. So, the CallMeBack method will be called. Basically, we are passing delegate to call the callback method.

Please let me know if you have any questions.

In case it helps someone, in my case I was using a custom package in release mode instead of in debug mode.

I just changed the package from "release" to "debug" and it worked.

I was looking for a similar solution, but the ones mentioned here would not work. My data had all variations of whitespace (space, newline, tab) chars and commas.

To make the column data tsv safe, I replaced all \t chars in the column data with a space, and executed python code on the commandline to generate a csv file, as shown below:

hive -e 'tab_replaced_hql_query' |  python -c 'exec("import sys;import csv;reader = csv.reader(sys.stdin, dialect=csv.excel_tab);writer = csv.writer(sys.stdout, dialect=csv.excel)\nfor row in reader: writer.writerow(row)")'

This created a perfectly valid csv. Hope this helps those who come looking for this solution.

Use onClick event to clear value of target input, each time user clicks on field. This ensures that the onChange event will be triggered for the same file as well. Worked for me :)

onInputClick = (event) => {
    event.target.value = ''
}

<input type="file" onChange={onFileChanged} onClick={onInputClick} />

Using TypeScript

onInputClick = ( event: React.MouseEvent<HTMLInputElement, MouseEvent>) => {
    const element = event.target as HTMLInputElement
    element.value = ''
}

Here's an adaptation of CD Sanchez' answer that consistently returns a 6-digit colour code:

var stringToColour = function(str) {
  var hash = 0;
  for (var i = 0; i < str.length; i++) {
    hash = str.charCodeAt(i) + ((hash << 5) - hash);
  }
  var colour = '#';
  for (var i = 0; i < 3; i++) {
    var value = (hash >> (i * 8)) & 0xFF;
    colour += ('00' + value.toString(16)).substr(-2);
  }
  return colour;
}

Usage:

stringToColour("greenish");
// -> #9bc63b

Example:

http://jsfiddle.net/sUK45/

(An alternative/simpler solution might involve returning an 'rgb(...)'-style colour code.)

You may try this CSS. I have experienced it working always.

div {
  border-style: solid;
  padding: 5px;
}

table {
  width: 100%;
  word-break: break-all;
  border-style: solid;
}

<div style="width:200px;">
  <table>
    <tr>
      <th>Col 1</th>
      <th>Col 2</th>
      <th>Col 3</th>
      <th>Col 4</th>
      <th>Col 5</th>
    </tr>
    <tr>
      <td>data 1</td>
      <td>data 2</td>
      <td>data 3</td>
      <td>data 4</td>
      <td>data 5</td>
    </tr>
    <table>
</div>

int space = 40;
printf("%*s", space, "Hello");

This statement will reserve a row of 40 characters, print string at the end of the row (removing extra spaces such that the total row length is constant at 40). Same can be used for characters and integers as follows:

printf("%*d", space, 10);
printf("%*c", space, 'x');

This method using a parameter to determine spaces is useful where a variable number of spaces is required. These statements will still work with integer literals as follows:

printf("%*d", 10, 10);
printf("%*c", 20, 'x');
printf("%*s", 30, "Hello");

Hope this helps someone like me in future.

Disablend ScrollView

ScrollView sw = (ScrollView) findViewById(R.id.scrollView1);
sw.setOnTouchListener(new OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {
        return true;
    }
});

COPY README.md package.json gulpfile.js __BUILD_NUMBER ./

or

COPY ["__BUILD_NUMBER", "README.md", "gulpfile", "another_file", "./"]

You can also use wildcard characters in the sourcefile specification. See the docs for a little more detail.

Directories are special! If you write

COPY dir1 dir2 ./

that actually works like

COPY dir1/* dir2/* ./

If you want to copy multiple directories (not their contents) under a destination directory in a single command, you'll need to set up the build context so that your source directories are under a common parent and then COPY that parent.

It also helps to ensure libmysqlclient-dev is installed (Ubuntu 14.04)

You could opt for a pure CSS solution:

#hfont1 {
    transition: color 1s ease-in-out;
    -moz-transition: color 1s ease-in-out; /* FF 4 */
    -webkit-transition: color 1s ease-in-out; /* Safari & Chrome */
    -o-transition: color 1s ease-in-out; /* Opera */
}

Scenario Two: The Microsoft Visual Studio 2010 IDE crashes while creating OR debugging a web application project. This above error occurs because of corrupted Cache of Visual Studio 2010. In order to resolve the issue just delete the project Cache from the below location:

C:\Program Files\Microsoft Visual Studio 10.0\Common7\IDE\ProjectTemplatesCache

C:\Program Files(x86)\Microsoft Visual Studio 10.0\Common7\IDE\ProjectTemplatesCache

Then run devenv.exe /setup to re-build the cache.

Yesterday Date can be calculated as:-

let now = new Date();
    var defaultDate = now - 1000 * 60 * 60 * 24 * 1;
    defaultDate = new Date(defaultDate);

Using Google Guava:

CharMatcher.inRange('0','9').retainFrom("123-456-789")

UPDATE:

Using Precomputed CharMatcher can further improve performance

CharMatcher ASCII_DIGITS=CharMatcher.inRange('0','9').precomputed();  
ASCII_DIGITS.retainFrom("123-456-789");

A token is a piece of data which only Server X could possibly have created, and which contains enough data to identify a particular user.

You might present your login information and ask Server X for a token; and then you might present your token and ask Server X to perform some user-specific action.

Tokens are created using various combinations of various techniques from the field of cryptography as well as with input from the wider field of security research. If you decide to go and create your own token system, you had best be really smart.

If a is your array:

In [11]: a[:,:2]
Out[11]: 
array([[-0.57098887, -0.4274751 ],
       [-0.22279713, -0.51723555],
       [ 0.67492385, -0.69294472],
       [ 0.41086611,  0.26374238]])

What you have done is created a new anonymous function that takes a single parameter which then gets assigned to the local variable myMessage inside the function. Since no arguments are actually passed, and arguments which aren't passed a value become null, your function just does alert(null).

Environment variables can be set, by creating a setenv.bat (windows) or setenv.sh (unix) file in the bin folder of your tomcat installation directory. However, environment variables will not be accessabile from within your code.

System properties are set by -D arguments of the java process. You can define java starting arguments in the environment variable JAVA_OPTS.

My suggestions is the combination of these two mechanisms. In your apache-tomcat-0.0.0\bin\setenv.bat write:

set JAVA_OPTS=-DAPP_MASTER_PASSWORD=password1

and in your Java code write:

System.getProperty("APP_MASTER_PASSWORD")

Model.find

1- Parameter: ID of the object to find.

2- If found: It returns the object (One object only).

3- If not found: raises an ActiveRecord::RecordNotFound exception.

Model.find_by

1- Parameter: key/value

Example:

User.find_by name: 'John', email: '[email protected]'

2- If found: It returns the object.

3- If not found: returns nil.

Note: If you want it to raise ActiveRecord::RecordNotFound use find_by!

Model.where

1- Parameter: same as find_by

2- If found: It returns ActiveRecord::Relation containing one or more records matching the parameters.

3- If not found: It return an Empty ActiveRecord::Relation.

alternatively you can also do this:

p '< echo "x y"' w impulse

x and y are the coordinates of the point to which you draw a vertical bar

You can change the database name using MySQL interface.

Go to http://www.hostname.com/phpmyadmin

Go to database which you want to rename. Next, go to the operation tab. There you will find the input field to rename the database.

You can use this one-liner:

cat 1.txt | xargs echo rm | sh

Which does shell expansion but executes rm the minimum number of times.

The Apache iBatis solution worked like a charm.

The script example I used was exactly the script I was running from MySql workbench.

There is an article with examples here: https://www.tutorialspoint.com/how-to-run-sql-script-using-jdbc#:~:text=You%20can%20execute%20.,to%20pass%20a%20connection%20object.&text=Register%20the%20MySQL%20JDBC%20Driver,method%20of%20the%20DriverManager%20class.

This is what I did:

pom.xml dependency

<!-- IBATIS SQL Script runner from Apache (https://mvnrepository.com/artifact/org.apache.ibatis/ibatis-core) -->
<dependency>
    <groupId>org.apache.ibatis</groupId>
    <artifactId>ibatis-core</artifactId>
    <version>3.0</version>
</dependency>

Code to execute script:

import java.io.BufferedReader;
import java.io.File;
import java.io.FileReader;
import java.io.Reader;
import java.sql.Connection;   
import org.apache.ibatis.jdbc.ScriptRunner;   
import lombok.extern.slf4j.Slf4j;

@Slf4j
public class SqlScriptExecutor {

    public static void executeSqlScript(File file, Connection conn) throws Exception {
        Reader reader = new BufferedReader(new FileReader(file));
        log.info("Running script from file: " + file.getCanonicalPath());
        ScriptRunner sr = new ScriptRunner(conn);
        sr.setAutoCommit(true);
        sr.setStopOnError(true);
        sr.runScript(reader);
        log.info("Done.");
    }
    
}

GCC has a switch called

-fno-inline-small-functions

So use that when invoking gcc. But the side effect is that all other small functions are also non-inlined.

glOrtho describes a transformation that produces a parallel projection. The current matrix (see glMatrixMode) is multiplied by this matrix and the result replaces the current matrix, as if glMultMatrix were called with the following matrix as its argument:

OpenGL documentation (my bold)

The numbers define the locations of the clipping planes (left, right, bottom, top, near and far).

The "normal" projection is a perspective projection that provides the illusion of depth. Wikipedia defines a parallel projection as:

Parallel projections have lines of projection that are parallel both in reality and in the projection plane.

Parallel projection corresponds to a perspective projection with a hypothetical viewpoint—e.g., one where the camera lies an infinite distance away from the object and has an infinite focal length, or "zoom".

You can use rows and cols:

cout << "Width : " << src.cols << endl;
cout << "Height: " << src.rows << endl;

or size():

cout << "Width : " << src.size().width << endl;
cout << "Height: " << src.size().height << endl;

Since I can't comment on the top comment, I'm forced to submit an "answer."

The problem with the selected answer is that setting the field to readonly takes the field out of the tab order on the iPhone. So if you like entering forms by hitting "next", you'll skip right over the field.

Be warned - this is a very old and cumbersome "solution".

By the way, you can use serialization technology to send strings, numbers or any objects which are support serialization (most of .NET data-storing classes & structs are [Serializable]). There, you should at first send Int32-length in four bytes to the stream and then send binary-serialized (System.Runtime.Serialization.Formatters.Binary.BinaryFormatter) data into it.

On the other side or the connection (on both sides actually) you definetly should have a byte[] buffer which u will append and trim-left at runtime when data is coming.

Something like that I am using:

            StartReceive();

        public void Dispose() { DropConnection(); }
    }
}

That is just an example, you should edit it for your use.

This will also work :

with data as 
(
select sal,rwid from (
select salary as sal,rowid as rwid from salary order by salary desc
)
where rownum < 5
)
select * from salary a 
where rowid = (select min(rwid) from data)

I've used bundle update --source myself for a long time but there are scenarios where it doesn't work. Luckily, there's a gem called bundler-patch which has the goal of fixing this shortcoming.

I also wrote a short blog post about how to use bundler-patch and why bundle update --source doesn't work consistently. Also, be sure to check out a post by chrismo that explains in great detail what the --source option does.

To work with NpgsqlCommand or the standard sqlCommand use:

int result = int.Parse(cmd.ExecuteScalar().ToString());

It looks like the phoneGap plugin will allow you to get the device's uid.

http://docs.phonegap.com/en/3.0.0/cordova_device_device.md.html#device.uuid

Update: This is dependent on running native code. We used this solution writing javascript that was being compiled to native code for a native phone application we were creating.

You're looking for iotop (assuming you've got kernel >2.6.20 and Python 2.5). Failing that, you're looking into hooking into the filesystem. I recommend the former.

I had a similar problem, needed to trim trailing zeros from numbers like xx0000,x00000,xxx000

I used:

select LEFT(code,LEN(code)+1 - PATINDEX('%[1-Z]%',REVERSE(code))) from Tablename

Code is the name of the field with the number to be trimmed. Hope this helps someone else.

To cut a JSON item into parts I add "dummy comment" lines:

{

"#############################" : "Part1",

"data1"             : "value1",
"data2"             : "value2",

"#############################" : "Part2",

"data4"             : "value3",
"data3"             : "value4"

}

The humanize app offers a nice and a quick way of formatting a number but if you need to use a separator different from the comma, it's simple to just reuse the code from the humanize app, replace the separator char, and create a custom filter. For example, use space as a separator:

@register.filter('intspace')
def intspace(value):
    """
    Converts an integer to a string containing spaces every three digits.
    For example, 3000 becomes '3 000' and 45000 becomes '45 000'.
    See django.contrib.humanize app
    """
    orig = force_unicode(value)
    new = re.sub("^(-?\d+)(\d{3})", '\g<1> \g<2>', orig)
    if orig == new:
        return new
    else:
        return intspace(new)

Here are a few things you need to do:

1-Download the library if you haven't already done that.

2- Import into Eclipse.

3- Set you project to use the library: Project-> Properties -> Android -> Scroll down to Library section, click Add... and select viewpagerindicator.

4- Now you should be able to import com.viewpagerindicator.TitlePageIndicator.

Now about implementing this without using fragments:

In the sample that comes with viewpagerindicatior, you can see that the library is being used with a ViewPager which has a FragmentPagerAdapter.

But in fact the library itself is Fragment independant. It just needs a ViewPager. So just use a PagerAdapter instead of a FragmentPagerAdapter and you're good to go.

Here's a nice trick to read JSON from s3:

import json, boto3
s3 = boto3.resource("s3").Bucket("bucket")
json.load_s3 = lambda f: json.load(s3.Object(key=f).get()["Body"])
json.dump_s3 = lambda obj, f: s3.Object(key=f).put(Body=json.dumps(obj))

Now you can use json.load_s3 and json.dump_s3 with the same API as load and dump

data = {"test":0}
json.dump_s3(data, "key") # saves json to s3://bucket/key
data = json.load_s3("key") # read json from s3://bucket/key

redirect to ../

How about something like this?

val newDF = df.filter($"B" === "").take(1) match {
  case Array() => df
  case _ => df.withColumn("D", $"B" === "")
}

Using take(1) should have a minimal hit

From the manpage, I believe these are the droids you are looking for:

-F/--form <name=content>

(HTTP) This lets curl emulate a filled-in form in which a user has pressed the submit button. This causes curl to POST data using the Content-Type multipart/form-data according to RFC2388. This enables uploading of binary files etc. To force the 'content' part to be a file, prefix the file name with an @ sign.

Example, to send your password file to the server, where 'password' is the name of the form-field to which /etc/passwd will be the input:

curl -F password=@/etc/passwd www.mypasswords.com

So in your case, this would be something like
curl -F file=@/some/file/on/your/local/disk http://localhost:8080

In c++, compiler always ensure that functions in object hierarchy are called successfully. These functions are constructors and destructors and object hierarchy means inheritance tree.

According to this rule we can guess compiler will call constructors and destructors for each object in inheritance hierarchy even if we don't implement it. To perform this operation compiler will synthesize the undefined constructors and destructors for us and we name them as a default constructors and destructors.Then, compiler will call default constructor of base class and then calls constructor of derived class.

In your case you don't call base class constructor but compiler does that for you by calling default constructor of base class because if compiler didn't do it your derived class which is Rectangle in your example will not be complete and it might cause disaster because maybe you will use some member function of base class in your derived class. So for the sake of safety compiler always need all constructor calls.

The two approaches are not interchangeable. You should initialize state in the constructor when using ES6 classes, and define the getInitialState method when using React.createClass.

See the official React doc on the subject of ES6 classes.

class MyComponent extends React.Component {
  constructor(props) {
    super(props);
    this.state = { /* initial state */ };
  }
}

is equivalent to

var MyComponent = React.createClass({
  getInitialState() {
    return { /* initial state */ };
  },
});

If you install TortoiseSVN you can use SVN under windows. It also gives you the SVN binaries. You needn't do the checkout from the command-line though as it integrates into Windows Explorer for you.

If you're working in a large multi-module project, with several different application.properties files, then try adding your value to the parent project's property file.

If you are unsure which is your parent project, check your project's pom.xml file, for a <parent> tag.

This solved the issue for me.

You can't "directly" mock static method (hence extension method) with mocking framework. You can try Moles (http://research.microsoft.com/en-us/projects/pex/downloads.aspx), a free tool from Microsoft that implements a different approach. Here is the description of the tool:

Moles is a lightweight framework for test stubs and detours in .NET that is based on delegates.

Moles may be used to detour any .NET method, including non-virtual/static methods in sealed types.

You can use Moles with any testing framework (it's independent about that).

Similar to Roko C, but a little more control over size and placement.

You could also just call to_a after each_byte or even better String#bytes

=> 'hello world'.each_byte.to_a
=> [104, 101, 108, 108, 111, 32, 119, 111, 114, 108, 100]

=> 'hello world'.bytes
=> [104, 101, 108, 108, 111, 32, 119, 111, 114, 108, 100]

in JDK 8, jdbc odbc bridge is no longer used and thus removed fro the JDK. to use Microsoft Access database in JAVA, you need 5 extra JAR libraries.

1- hsqldb.jar

2- jackcess 2.0.4.jar

3- commons-lang-2.6.jar

4- commons-logging-1.1.1.jar

5- ucanaccess-2.0.8.jar

add these libraries to your java project and start with following lines.

Connection conn=DriverManager.getConnection("jdbc:ucanaccess://<Path to your database i.e. MS Access DB>");
Statement s = conn.createStatement();

path could be like E:/Project/JAVA/DBApp

and then your query to be executed. Like

ResultSet rs = s.executeQuery("SELECT * FROM Course");
while(rs.next())
    System.out.println(rs.getString("Title") + " " + rs.getString("Code") + " " + rs.getString("Credits"));

certain imports to be used. try catch block must be used and some necessary things no to be forgotten.

Remember, no need of bridging drivers like jdbc odbc or any stuff.

If you are using TOAD, you will need to download the 32-bit version of the Oracle Client Tools.

Since the Client Tools are different on a per-processor architecture basis, you probably need to install versions.

Maybe a bit late, but: instead of this:

public void onNewIntent(Intent intent){
    Bundle extras = intent.getExtras();
    Log.i( "dbg","onNewIntent");

    if(extras != null){
        Log.i( "dbg", "Extra6 bool: "+ extras.containsKey("net.dbg.android.fjol"));
        Log.i( "dbg", "Extra6 val : "+ extras.getString("net.dbg.android.fjol"));

    }
    mTabsController.setActiveTab(TabsController.TAB_DOWNLOADS);
}

Use this:

Bundle extras = getIntent().getExtras();
if(extras !=null) {
    String value = extras.getString("keyName");
}

Here's an alternate solution that actually adds your certificate to the built in list of default certificates: Trusting all certificates using HttpClient over HTTPS

However, it will only work for your application. There's no way to programmatically do it for all applications on a user's device, since that would be a security risk.

This works with font awesome:

<button class="btn btn-outline-success">
   <i class="fa fa-print" aria-hidden="true"></i>
   Print
</button>

A little late reply, but what I found in Notepad++ v7.8.6 is, on RMB (Right Mouse Button), on selection text, it gives an option called "Style token" where it shows "Using 1st/2nd/3rd/4th/5th style" to highlight the selected text in different pre-defined colors

With Spring 4 you only add @EnableWebMvc, for example:

@Controller
@EnableWebMvc
@RequestMapping(value = "/articles/action", headers="Accept=*/*",  produces="application/json")
public class ArticlesController {

}

The application is a server which simply runs until the system shuts down or it receives a Ctrl+C or the console window is closed.

Due to the extraordinary nature of the application, it is not feasible to "gracefully" exit. (It may be that I could code another application which would send a "server shutdown" message but that would be overkill for one application and still insufficient for certain circumstances like when the server (Actual OS) is actually shutting down.)

Because of these circumstances I added a "ConsoleCtrlHandler" where I stop my threads and clean up my COM objects etc...

Public Declare Auto Function SetConsoleCtrlHandler Lib "kernel32.dll" (ByVal Handler As HandlerRoutine, ByVal Add As Boolean) As Boolean

Public Delegate Function HandlerRoutine(ByVal CtrlType As CtrlTypes) As Boolean

Public Enum CtrlTypes
  CTRL_C_EVENT = 0
  CTRL_BREAK_EVENT
  CTRL_CLOSE_EVENT
  CTRL_LOGOFF_EVENT = 5
  CTRL_SHUTDOWN_EVENT
End Enum

Public Function ControlHandler(ByVal ctrlType As CtrlTypes) As Boolean
.
.clean up code here
.
End Function

Public Sub Main()
.
.
.
SetConsoleCtrlHandler(New HandlerRoutine(AddressOf ControlHandler), True)
.
.
End Sub

This setup seems to work out perfectly. Here is a link to some C# code for the same thing.

platform independent approach (uses File.separator, ie will works depends on operation system where code is running:

java.nio.file.Paths.get(".", "path", "to", "file.txt")
// relative unix path: ./path/to/file.txt
// relative windows path: .\path\to\filee.txt

java.nio.file.Paths.get("/", "path", "to", "file.txt")
// absolute unix path: /path/to/filee.txt
// windows network drive path: \\path\to\file.txt

java.nio.file.Paths.get("C:", "path", "to", "file.txt")
// absolute windows path: C:\path\to\file.txt

The below works for me

dataframe[,"newName"] <- NA

Make sure to add "" for new name string.

Between execution of left != null and queue.add(left) another thread could have changed the value of left to null.

To work around this you have several options. Here are some:

1. Use a local variable with smart cast:

    val node = left
    if (node != null) {
        queue.add(node)
    }
   

2. Use a safe call such as one of the following:

    left?.let { node -> queue.add(node) }
    left?.let { queue.add(it) }
    left?.let(queue::add)
   

3. Use the Elvis operator with return to return early from the enclosing function:

    queue.add(left ?: return)
   

   Note that break and continue can be used similarly for checks within loops.

Just been working on something very similar, I am not an expert but I thought I would share the commands I have used. I had a multi column csv which I only required 4 columns out of and then I needed to reorder them.

My file was pipe '|' delimited but that can be swapped out.

LC_ALL=C cut -d$'|' -f1,2,3,8,10 ./file/location.txt | sed -E "s/(.*)\|(.*)\|(.*)\|(.*)\|(.*)/\3\|\5\|\1\|\2\|\4/" > ./newcsv.csv

Admittedly it is really rough and ready but it can be tweaked to suit!

Following worked for me.

1. Open another instance of Application Loader. ( Select "Application Loader" under the "Xcode -> Open Developer Tool" menu)

2. "Agree" to the terms.

3. After completing Step 2. First instance of Application Loader proceeded to the next step and build got submitted.

Your example would be:

int num1 = 1;
int num2 = 1;

num1 = num2 = 5;

Use two single-quotes

SQL> SELECT 'D''COSTA' name FROM DUAL;

NAME
-------
D'COSTA

Alternatively, use the new (10g+) quoting method:

SQL> SELECT q'$D'COSTA$' NAME FROM DUAL;

NAME
-------
D'COSTA

I figured it out myself. I need

select extract(day from sysdate - to_date('2009-10-01', 'yyyy-mm-dd')) from dual

Java doesn't overload operators, so you'll usually need a method for non-basic types. Try the Arrays.equals() method.

To avoid caching of output you might wanna try pexpect,

child = pexpect.spawn(launchcmd,args,timeout=None)
while True:
    try:
        child.expect('\n')
        print(child.before)
    except pexpect.EOF:
        break

PS : I know this question is pretty old, still providing the solution which worked for me.

PPS: got this answer from another question

I wouldn't advise this, it goes against standard practices, and doesn't offer that much in return. You want to keep the body for content, not options.

For me the issue was in Resharper License. It has been delinked from my account for some reason and it said that the license is invalid. When I linked it again to my JetBrains account it started to work properly after a few minutes.

Just include following in your code

<body background="C:\Users\Desktop\images.jpg"> 

if you want to specify the size and opacity you can use following

<p><img style="opacity:0.9;" src="C:\Users\Desktop\images.jpg" width="300" height="231" alt="Image" /></p> 

If the column expanded only by contiguously added dates as in my case - I used just MAX function to get last date.

The final formula will be:

=DAYS360(A2; MAX(A2:A)) 

You can revert only one file to a specified revision.

First you can check on which commits the file was changed.

git log path/to/file.txt

Then you can checkout the file with the revision number.

git checkout 3cdc61015724f9965575ba954c8cd4232c8b42e4 /path/to/file.txt

After that you can commit and push it again.

You can flip both vertical and horizontal at the same time

    -moz-transform: scaleX(-1) scaleY(-1);
    -o-transform: scaleX(-1) scaleY(-1);
    -webkit-transform: scaleX(-1) scaleY(-1);
    transform: scaleX(-1) scaleY(-1);

And with the transition property you can get a cool flip

    -webkit-transition: transform .4s ease-out 0ms;
    -moz-transition: transform .4s ease-out 0ms;
    -o-transition: transform .4s ease-out 0ms;
    transition: transform .4s ease-out 0ms;
    transition-property: transform;
    transition-duration: .4s;
    transition-timing-function: ease-out;
    transition-delay: 0ms;

Actually it flips the whole element, not just the background-image

 var myDiv = document.getElementById('myDiv');_x000D_

It would appear that the ** syntax is supported by git as of version 1.8.2.1 according to the documentation.

Two consecutive asterisks ("**") in patterns matched against full pathname may have special meaning:

• A leading "**" followed by a slash means match in all directories. For example, "**/foo" matches file or directory "foo" anywhere, the same as pattern "foo". "**/foo/bar" matches file or directory "bar" anywhere that is directly under directory "foo".

• A trailing "/**" matches everything inside. For example, "abc/**" matches all files inside directory "abc", relative to the location of the .gitignore file, with infinite depth.

• A slash followed by two consecutive asterisks then a slash matches zero or more directories. For example, "a/**/b" matches "a/b", "a/x/b", "a/x/y/b" and so on.

• Other consecutive asterisks are considered invalid.

It seems no clear document talking on the Gemfile.lock format. Maybe it's because Gemfile.lock is just used by bundle internally.

However, since Gemfile.lock is a snapshot of Gemfile, which means all its information should come from Gemfile (or from default value if not specified in Gemfile).

For GEM, it lists all the dependencies you introduce directly or indirectly in the Gemfile. remote under GEM tells where to get the gems, which is specified by source in Gemfile.

If a gem is not fetch from remote, PATH tells the location to find it. PATH's info comes from path in Gemfile when you declare a dependency.

And PLATFORM is from here.

For DEPENDENCIES, it's the snapshot of dependencies resolved by bundle.

While trying out the

pip install boto

command, I encounter the error

ImportError: No module named pkg_resources

To resolve this, issue another command to handle the setuptools using curl

curl https://bootstrap.pypa.io/ez_setup.py | python

After doing that, the following command will work perfectly.

pip install boto

You pass an undefined rAgent_IP parameter in EXEC instead of the local variable @rAgent_IP.

Still, this trigger will fail if you perform a multi-record INSERT statement.

There is also this one:

hash = { foo: "bar", baz: "qux" }
hash.map(&:last) #=> ["bar", "qux"]

Why it works:

The & calls to_proc on the object, and passes it as a block to the method.

something {|i| i.foo }
something(&:foo)

In case it helps anyone, the C# equivalent of ZloiAdun's answer is:

element.SendKeys(Keys.Control + "a");
element.SendKeys("55");

I spend a whole day organizing this information for my company since we are building a multi-lingual platform.

There are three ways scope can be added in the directive:

1. Parent scope: This is the default scope inheritance.

The directive and its parent(controller/directive inside which it lies) scope is same. So any changes made to the scope variables inside directive are reflected in the parent controller as well. You don't need to specify this as it is the default.

2. Child scope: directive creates a child scope which inherits from the parent scope if you specify the scope variable of the directive as true.

Here, if you change the scope variables inside directive, it won't reflect in the parent scope, but if you change the property of a scope variable, that is reflected in the parent scope, as you actually modified the scope variable of the parent.

Example,

app.directive("myDirective", function(){

    return {
        restrict: "EA",
        scope: true,
        link: function(element, scope, attrs){
            scope.somvar = "new value"; //doesnot reflect in the parent scope
            scope.someObj.someProp = "new value"; //reflects as someObj is of parent, we modified that but did not override.
        }
    };
});

3. Isolated scope: This is used when you want to create the scope that does not inherit from the controller scope.

This happens when you are creating plugins as this makes the directive generic since it can be placed in any HTML and does not gets affected by its parent scope.

Now, if you don't want any interaction with the parent scope, then you can just specify scope as an empty object. like,

scope: {} //this does not interact with the parent scope in any way

Mostly this is not the case as we need some interaction with the parent scope, so we want some of the values/ changes to pass through. For this reason, we use:

1. "@"   (  Text binding / one-way binding )
2. "="   ( Direct model binding / two-way binding )
3. "&"   ( Behaviour binding / Method binding  )

@ means that the changes from the controller scope will be reflected in the directive scope but if you modify the value in the directive scope, the controller scope variable will not get affected.

@ always expects the mapped attribute to be an expression. This is very important; because to make the “@” prefix work, we need to wrap the attribute value inside {{}}.

= is bidirectional so if you change the variable in directive scope, the controller scope variable gets affected as well

& is used to bind controller scope method so that if needed we can call it from the directive

The advantage here is that the name of the variable need not be same in controller scope and directive scope.

Example, the directive scope has a variable "dirVar" which syncs with variable "contVar" of the controller scope. This gives a lot of power and generalization to the directive as one controller can sync with variable v1 while another controller using the same directive can ask dirVar to sync with variable v2.

Below is the example of usage:

The directive and controller are:

 var app = angular.module("app", []);
 app.controller("MainCtrl", function( $scope ){
    $scope.name = "Harry";
    $scope.color = "#333333";
    $scope.reverseName = function(){
     $scope.name = $scope.name.split("").reverse().join("");
    };
    $scope.randomColor = function(){
        $scope.color = '#'+Math.floor(Math.random()*16777215).toString(16);
    };
});
app.directive("myDirective", function(){
    return {
        restrict: "EA",
        scope: {
            name: "@",
            color: "=",
            reverse: "&"
        },
        link: function(element, scope, attrs){
           //do something like
           $scope.reverse(); 
          //calling the controllers function
        }
    };
});

And the html(note the differnce for @ and =):

<div my-directive
  class="directive"
  name="{{name}}"
  reverse="reverseName()"
  color="color" >
</div>

Here is a link to the blog which describes it nicely.

You have to take whole columns under resizebox. This code worked for me

\begin{table}[htbp]

INSERT syntax cannot have WHERE but you can use UPDATE.

The syntax is as follows:

UPDATE table_name

SET column1 = value1, column2 = value2, ...

WHERE condition;

    //create TreeMap instance
    TreeMap treeMap = new TreeMap();

    //add key value pairs to TreeMap
    treeMap.put("1","One");
    treeMap.put("2","Two");
    treeMap.put("3","Three");

    /*
      get Collection of values contained in TreeMap using
      Collection values()        
    */
    Collection c = treeMap.values();

    //obtain an Iterator for Collection
    Iterator itr = c.iterator();

    //iterate through TreeMap values iterator
    while(itr.hasNext())
      System.out.println(itr.next());

or:

   for (Map.Entry<K,V> entry : treeMap.entrySet()) {
        V value = entry.getValue();
        K key = entry.getKey();
   }

or:

   // Use iterator to display the keys and associated values
   System.out.println("Map Values Before: ");
   Set keys = map.keySet();
   for (Iterator i = keys.iterator(); i.hasNext();) {
     Integer key = (Integer) i.next();
     String value = (String) map.get(key);
     System.out.println(key + " = " + value);
   }

The following works for me... S3 objects:

s3://bucket/
    form1/
       section11/
          file111
          file112
       section12/
          file121
    form2/
       section21/
          file211
          file112
       section22/
          file221
          file222
          ...
      ...
   ...

Using:

from boto3.session import Session
s3client = session.client('s3')
resp = s3client.list_objects(Bucket=bucket, Prefix='', Delimiter="/")
forms = [x['Prefix'] for x in resp['CommonPrefixes']] 

we get:

form1/
form2/
...

With:

resp = s3client.list_objects(Bucket=bucket, Prefix='form1/', Delimiter="/")
sections = [x['Prefix'] for x in resp['CommonPrefixes']] 

we get:

form1/section11/
form1/section12/

node-crontab allows you to edit system cron jobs from node.js. Using this library will allow you to run programs even after your main process termintates. Disclaimer: I'm the developer.

Based on the @trashgod's comment, this is the simpliest way to calculate distance:

double distance = Math.hypot(x1-x2, y1-y2);

From documentation of Math.hypot:

Returns: sqrt(x²+ y²) without intermediate overflow or underflow.

While I currently lean toward RDL because it seems more flexible and easier to manage, RDLC has an advantage in that it seems to simplify your licensing. Because RDLC doesn’t need a Reporting Services instance, you won't need a Reporting Services License to use it.

I’m not sure if this still applies with the newer versions of SQL Server, but at one time if you chose to put the SQL Server Database and Reporting Services instances on two separate machines, you were required to have two separate SQL Server licenses:

The datadir is the location where your MySQL database is stored.

The most important reasons to start your next project using Node ...

• All the coolest dudes are into it ... so it must be fun.
• You can hangout at the cooler and have lots of Node adventures to brag about.
• You're a penny pincher when it comes to cloud hosting costs.
• Been there done that with Rails
• You hate IIS deployments
• Your old IT job is getting rather dull and you wish you were in a shiny new Start Up.

What to expect ...

• You'll feel safe and secure with Express without all the server bloatware you never needed.
• Runs like a rocket and scales well.
• You dream it. You installed it. The node package repo npmjs.org is the largest ecosystem of open source libraries in the world.
• Your brain will get time warped in the land of nested callbacks ...
• ... until you learn to keep your Promises.
• Sequelize and Passport are your new API friends.
• Debugging mostly async code will get umm ... interesting .
• Time for all Noders to master Typescript.

Who uses it?

• PayPal, Netflix, Walmart, LinkedIn, Groupon, Uber, GoDaddy, Dow Jones
• Here's why they switched to Node.

This usually appears when you want to use UIActivityViewController in iPad.

Add below, before you present the controller to mark the arrow.

activityViewController.popoverPresentationController?.sourceRect = senderView.frame // senderView can be your button/view you tapped to call this VC

I assume you already have below, if not, add together:

activityViewController.popoverPresentationController?.sourceView = self.view

For powershell in Windows, you can add relative path + filename to --output flag:

curl -L  http://github.com/GorvGoyl/Notion-Boost-browser-extension/archive/master.zip --output build_firefox/master-repo.zip

here build_firefox is relative folder.

Since the frameborder attribute is only necessary for IE, there is another way to get around the validator. This is a lightweight way that doesn't require Javascript or any DOM manipulation.

<!--[if IE]>
   <iframe src="source" frameborder="0">?</iframe>
<![endif]-->
<!--[if !IE]>-->
   <iframe src="source" style="border:none">?</iframe>
<!-- <![endif]-->

Move all of your state and your handleClick function from Header to your MainWrapper component.

Then pass values as props to all components that need to share this functionality.

class MainWrapper extends React.Component {
    constructor() {
        super();
        this.state = {
            sidbarPushCollapsed: false,
            profileCollapsed: false
        };
        this.handleClick = this.handleClick.bind(this);
    }
    handleClick() {
        this.setState({
            sidbarPushCollapsed: !this.state.sidbarPushCollapsed,
            profileCollapsed: !this.state.profileCollapsed

        });
    }
    render() {
        return (
           //...
           <Header 
               handleClick={this.handleClick} 
               sidbarPushCollapsed={this.state.sidbarPushCollapsed}
               profileCollapsed={this.state.profileCollapsed} />
        );

Then in your Header's render() method, you'd use this.props:

<button type="button" id="sidbarPush" onClick={this.props.handleClick} profile={this.props.profileCollapsed}>

You could also use a CTE to grab groups of information you want and join them together, if you wanted them in the same row. Example, depending on which SQL syntax you use, here:

WITH group1 AS (
  SELECT testA
    FROM tableA
),
group2 AS (
  SELECT testB
    FROM tableB 
)
SELECT *
  FROM group1
  JOIN group2 ON group1.testA = group2.testB --your choice of join
;

You decide what kind of JOIN you want based on the data you are pulling, and make sure to have the same fields in the groups you are getting information from in order to put it all into a single row. If you have multiple columns, make sure to name them all properly so you know which is which. Also, for performance sake, CTE's are the way to go, instead of inline SELECT's and such. Hope this helps.

Math.random()

Returns a double value with a positive sign, greater than or equal to 0.0 and less than 1.0.

Now it depends on what you want to accomplish. When you want to have Numbers from 1 to 100 for example you just have to add

(int)(Math.random()*100)

So 100 is the range of values. When you want to change the start of the range to 20 to 120 you have to add +20 at the end.

So the formula is:

(int)(Math.random()*range) + min

And you can always calculate the range with max-min, thats why Google gives you that formula.

Here is a compact ES6 friendly readable snippet

const stringHashCode = str => {
  let hash = 0
  for (let i = 0; i < str.length; ++i)
    hash = (Math.imul(31, hash) + str.charCodeAt(i)) | 0

  return hash
}

async() => {
let body = await model.find().or([
  { name: 'something'},
  { nickname: 'somethang'}
]).exec();
console.log(body);
}
/* Gives an array of the searched query!

I faced the same issue. My code was a .NET dll (AutoCAD extension) running inside AutoCAD 2012. I am also using Oracle.DataAccess and my code was throwing the same exception during ExecuteNonQuery(). I luckily solved this problem by changing the .net version of the ODP I was using (that is, 2.x of Oracle.DataAccess)

You're thinking too complicated. It's actually just $('#'+openaddress).

Ok, solved my problem, if anyone is passing by here is the answer:

Just had to add left: 0, and top: 0, to the styles, and yes, I'm tired.

position: 'absolute',
left:     0,
top:      0,

You have to figure out if the string is ascii encoded or encoded with a multi-byte format.

In the former case, you can just use strlen.

In the latter case you need to find the number of bytes per character.

the strlen documentation gives an example of how to do it : http://www.php.net/manual/en/function.strlen.php#72274

Given its complexibility, I think you should go the urlparse way.

For completeness, here's the pseudo-BNF of the above regex (as a documentation):

; The generic form of a URL is:

                 waisurl | mailtourl | fileurl |
                 prosperourl | otherurl

; new schemes follow the general syntax
otherurl       = genericurl

; the scheme is in lower case; interpreters should use case-ignore
scheme         = 1*[ lowalpha | digit | "+" | "-" | "." ]

Libraries cannot be directly used in any program if not properly added to the project gradle files.

This can easily be done in smart IDEs like inteli J.

1) First as a convention add a folder names 'libs' under your project src file. (this can easily be done using the IDE itself)

2) then copy or add your library file (eg: .jar file) to the folder named 'libs'

3) now you can see the library file inside the libs folder. Now right click on the file and select 'add as library'. And this will fix all the relevant files in your program and library will be directly available for your use.

Please note:

Whenever you are adding libraries to a project, make sure that the project supports the library

tabs: [...data.map((title) { return Text(title);}).toList(), extra_widget],

tabs: data.map((title) { return Text(title);}).toList(),

It's working fine for me

If you want to calculate a divided by b rounded up you can use (a+(-a%b))/b

int countRow = dt.Rows.Count;
int countCol = dt.Columns.Count;

for (int iCol = 0; iCol < countCol; iCol++)
{
     DataColumn col = dt.Columns[iCol];

     for (int iRow = 0; iRow < countRow; iRow++)
     {
         object cell = dt.Rows[iRow].ItemArray[iCol];

     }
}

This is now possible directly from nbconvert as of version 5.2.1: content can be filtered using the built-in template exporter exclude options. For example:

jupyter nbconvert --to pdf --TemplateExporter.exclude_input=True my_notebook.ipynb

will exclude the "input code" cells, ie the code itself. Similar options exist to exclude prompts, markdown cells, or outputs, or both inputs and outputs.

(These options should work irrespective of output format.)

You can also use showdialog

Private Sub Button3_Click(sender As System.Object, e As System.EventArgs) _
                      Handles Button3.Click

     dim mydialogbox as new aboutbox1
     aboutbox1.showdialog()

End Sub

While I am a big believer in reusing libraries, the org.apache.commons.io JAR is 174KB, which is noticably large for a mobile app.

If you download the source code and take a look at their FilenameUtils class, you can see there are a lot of extra utilities, and it does cope with Windows and Unix paths, which is all lovely.

However, if you just want a couple of static utility methods for use with Unix style paths (with a "/" separator), you may find the code below useful.

The removeExtension method preserves the rest of the path along with the filename. There is also a similar getExtension.

/**
 * Remove the file extension from a filename, that may include a path.
 * 
 * e.g. /path/to/myfile.jpg -> /path/to/myfile 
 */
public static String removeExtension(String filename) {
    if (filename == null) {
        return null;
    }

    int index = indexOfExtension(filename);

    if (index == -1) {
        return filename;
    } else {
        return filename.substring(0, index);
    }
}

/**
 * Return the file extension from a filename, including the "."
 * 
 * e.g. /path/to/myfile.jpg -> .jpg
 */
public static String getExtension(String filename) {
    if (filename == null) {
        return null;
    }

    int index = indexOfExtension(filename);

    if (index == -1) {
        return filename;
    } else {
        return filename.substring(index);
    }
}

private static final char EXTENSION_SEPARATOR = '.';
private static final char DIRECTORY_SEPARATOR = '/';

public static int indexOfExtension(String filename) {

    if (filename == null) {
        return -1;
    }

    // Check that no directory separator appears after the 
    // EXTENSION_SEPARATOR
    int extensionPos = filename.lastIndexOf(EXTENSION_SEPARATOR);

    int lastDirSeparator = filename.lastIndexOf(DIRECTORY_SEPARATOR);

    if (lastDirSeparator > extensionPos) {
        LogIt.w(FileSystemUtil.class, "A directory separator appears after the file extension, assuming there is no file extension");
        return -1;
    }

    return extensionPos;
}

add

.hover_img a:hover span {
    display: block;
    width: 350px;
}

to show hover image full size in table change 350 to your size.

Like this?

var iList = Method().SelectMany(n => n);

Thankfully, it's not possible to change the duration of the vibration. The only way to trigger the vibration is to play the kSystemSoundID_Vibrate as you have. If you really want to though, what you can do is to repeat the vibration indefinitely, resulting in a pulsing vibration effect instead of a long continuous one. To do this, you need to register a callback function that will get called when the vibration sound that you play is complete:

 AudioServicesAddSystemSoundCompletion (
        kSystemSoundID_Vibrate,
        NULL,
        NULL,
        MyAudioServicesSystemSoundCompletionProc,
        NULL
    );
    AudioServicesPlaySystemSound(kSystemSoundID_Vibrate);

Then you define your callback function to replay the vibrate sound again:

#pragma mark AudioService callback function prototypes
void MyAudioServicesSystemSoundCompletionProc (
   SystemSoundID  ssID,
   void           *clientData
);

#pragma mark AudioService callback function implementation

// Callback that gets called after we finish buzzing, so we 
// can buzz a second time.
void MyAudioServicesSystemSoundCompletionProc (
   SystemSoundID  ssID,
   void           *clientData
) {
  if (iShouldKeepBuzzing) { // Your logic here...
      AudioServicesPlaySystemSound(kSystemSoundID_Vibrate); 
  } else {
      //Unregister, so we don't get called again...
      AudioServicesRemoveSystemSoundCompletion(kSystemSoundID_Vibrate);
  }  
}

If anyone is experiencing this same problem when reading a frame from a webcam [with code similar to "frame = cv2.VideoCapture(0)"] and work in Jupyter Notebook, you may try:

0. ensure previously tried code is not running already and restart Jupyter Notebook kernel

1. SEPARATE code "frame = cv2.VideoCapture(0)" in separate cell on place where it is [previous code put in cell above, code under put to cell down]

2. then run all the code above cell where is "frame = cv2.VideoCapture(0)"

3. then try run next cell with its only code "frame = cv2.VideoCapture(0)" - AND - till you will continue in executing other cells - ENSURE - that ASTERIX on the left side of this particular cell DISAPEAR and command order number appear instead - only then continue

4. now you can try execute the rest of your code as your camera input should not be empty anymore :-)

5. After end, ensure you close all your program and restart kernel to prepare it for another run

This is a quick way to do that, I mean.

It does not use an expensive regex function. It also does not use multiple replacement functions that each individually did loop over the data with several checks, allocations, etc.

So the search is done directly in one for loop. For the number of times that the capacity of the result array has to be increased, a loop is also used within the Array.Copy function. That are all the loops. In some cases, a larger page size might be more efficient.

public static string NormalizeNewLine(this string val)
{

I now that '\n\r' is not actually used on basic platforms. But who would use two types of linebreaks in succession to indicate two linebreaks?

If you want to know that, then you need to take a look before to know if the \n and \r both are used separately in the same document.

First off, what compiler or dev environment are you using? If Visual Studio, you need to make a console application project to get console output.

Second,

std::cout << "Hello World" << std::endl;

should work in any C++ console application.

I had this problem. It took me ages to figure out. I had people over my shoulder to help. We rebuilt, cleaned and restarted Visual studio and this didn't fix it. We removed and re-added the references...

All to no avail.... Until!

The solution to my problem was that my class declaration was spelt incorrectly.

Before you start judging me harshly, allow me to explain why it wasn't stupid, and also why this mistake could be made by even the most intelligent of programmers.

Since the mistake was early on in the name, it wasn't appearing in the intellisense class listing when I began typing.

e.g.

Class name: Message.cs

Declaration:

public class Massage
{
    //code here

}

At a glance and in a small font, Massage looks identical to Message.

Typing M listed too many classes, so I typed e, which didn't appear in the mistyped version, which gave the impression that the class wasn't being picked up by the compiler.

This error can be caused by an unclosed set of brackets.

int main {
  doSomething {}
  doSomething else {
}

Not so easy to spot, even in this 4 line example.

This error, in a 150 line main function, caused the bewildering error: "static declaration of ‘savePair’ follows non-static declaration". There was nothing wrong with my definition of function savePair, it was that unclosed bracket.

This code will always fail.

As written, it says: "Look for a property named "Employee" on my DataContext property, and set it to the DataContext property". Clearly that isn't right.

To get your code to work, as is, change your window declaration to:

<Window x:Class="SampleApplication.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="clr-namespace:SampleApplication"
    Title="MainWindow" Height="350" Width="525">
<Window.DataContext>
   <local:Employee/>
</Window.DataContext>

This declares a new XAML namespace (local) and sets the DataContext to an instance of the Employee class. This will cause your bindings to display the default data (from your constructor).

However, it is highly unlikely this is actually what you want. Instead, you should have a new class (call it MainViewModel) with an Employee property that you then bind to, like this:

public class MainViewModel
{
   public Employee MyEmployee { get; set; } //In reality this should utilize INotifyPropertyChanged!
}

Now your XAML becomes:

<Window x:Class="SampleApplication.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:local="clr-namespace:SampleApplication"
        Title="MainWindow" Height="350" Width="525">
    <Window.DataContext>
       <local:MainViewModel/>
    </Window.DataContext>
    ...
    <TextBox Grid.Column="1" Grid.Row="0" Margin="3" Text="{Binding MyEmployee.EmpID}" />
    <TextBox Grid.Column="1" Grid.Row="1" Margin="3" Text="{Binding MyEmployee.EmpName}" />

Now you can add other properties (of other types, names), etc. For more information, see Implementing the Model-View-ViewModel Pattern

You can do both in one query using the OVER clause on another COUNT

select
    count(*) RecordsPerGroup,
    COUNT(*) OVER () AS TotalRecords
from temptable
group by column_1, column_2, column_3, column_4

When you mean user presses, do you mean a click? A click is when the user presses down and then immediately lifts up finger. Therefore it is encompassing two onTouch Events. You should save the use of onTouchEvent for stuff that happens on the initial touch or the after release.

Thus, you should be using onClickListener if it is a click.

Your answer is analogous: Use onLongClickListener.

One more difference that I can figure out is:

We can not use Dictionary<KT,VT> (generics) with web services. The reason is no web service standard supports the generics standard.

In some case NTLM authentication still won't work if given the correct credential.

There's a mechanism which will void NTLM auth within WebClient, see here for more information: System.Net.WebClient doesn't work with Windows Authentication

If you're trying above answer and it's still not working, follow the above link to add registry to make the domain whitelisted.

Post this here to save other's time ;)

CONNECTION_REFUSED is standard when the port is closed, but it could be rejected because SSL is failing authentication (one of a billion reasons). Did you configure SSL with Ratchet? (Apache is bypassed) Did you try without SSL in JavaScript?

I don't think Ratchet has built-in support for SSL. But even if it does you'll want to try the ws:// protocol first; it's a lot simpler, easier to debug, and closer to telnet. Chrome or the socket service may also be generating the REFUSED error if the service doesn't support SSL (because you explicitly requested SSL).

However the refused message is likely a server side problem, (usually port closed).

If you want to manually install NLTK Corpus.

1) Go to http://www.nltk.org/nltk_data/ and download your desired NLTK Corpus file.

2) Now in a Python shell check the value of nltk.data.path

3) Choose one of the path that exists on your machine, and unzip the data files into the corpora sub directory inside.

4) Now you can import the data from nltk.corpos import stopwords

I suggest you go see the script https://github.com/badele/gitcheck, i have coded this script for check in one pass all your git repositories, and it show who has not commited and who has not pushed/pulled.

Here a sample result

Just use the name of that variable.

In JavaScript, variables are only local to a function, if they are the function's parameter(s) or if you declare them as local explicitely by typing the var keyword before the name of the variable.

If the name of the local value has the same name as the global value, use the window object

See this jsfiddle

x = 1;_x000D_
y = 2;_x000D_
z = 3;_x000D_
_x000D_
function a(y) {_x000D_
  // y is local to the function, because it is a function parameter_x000D_
  console.log('local y: should be 10:', y); // local y through function parameter_x000D_
  y = 3; // will only overwrite local y, not 'global' y_x000D_
  console.log('local y: should be 3:', y); // local y_x000D_
  // global value could be accessed by referencing through window object_x000D_
  console.log('global y: should be 2:', window.y) // global y, different from local y ()_x000D_
_x000D_
  var x; // makes x a local variable_x000D_
  x = 4; // only overwrites local x_x000D_
  console.log('local x: should be 4:', x); // local x_x000D_
  _x000D_
  z = 5; // overwrites global z, because there is no local z_x000D_
  console.log('local z: should be 5:', z); // local z, same as global_x000D_
  console.log('global z: should be 5 5:', window.z, z) // global z, same as z, because z is not local_x000D_
}_x000D_
a(10);_x000D_
console.log('global x: should be 1:', x); // global x_x000D_
console.log('global y: should be 2:', y); // global y_x000D_
console.log('global z: should be 5:', z); // global z, overwritten in function a

Edit

With ES2015 there came two more keywords const and let, which also affect the scope of a variable (Language Specification)

Assuming you wanted to do this synchronously, using the WebClient.OpenRead(...) method and setting the timeout on the Stream that it returns will give you the desired result:

using (var webClient = new WebClient())
using (var stream = webClient.OpenRead(streamingUri))
{
     if (stream != null)
     {
          stream.ReadTimeout = Timeout.Infinite;
          using (var reader = new StreamReader(stream, Encoding.UTF8, false))
          {
               string line;
               while ((line = reader.ReadLine()) != null)
               {
                    if (line != String.Empty)
                    {
                        Console.WriteLine("Count {0}", count++);
                    }
                    Console.WriteLine(line);
               }
          }
     }
}

Deriving from WebClient and overriding GetWebRequest(...) to set the timeout @Beniamin suggested, didn't work for me as, but this did.

You can try the following code to request camera permission in marshmallow. First check if the user grant the permission. If user has not granted the permission, then request the camera permission:

private static final int MY_CAMERA_REQUEST_CODE = 100;

if (checkSelfPermission(Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED) {
    requestPermissions(new String[]{Manifest.permission.CAMERA}, MY_CAMERA_REQUEST_CODE);
}

After requesting the permission, dialog will display to ask permission containing allow and deny options. After clicking action we can get result of the request with the following method:

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    if (requestCode == MY_CAMERA_REQUEST_CODE) {
        if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
            Toast.makeText(this, "camera permission granted", Toast.LENGTH_LONG).show();
        } else {
            Toast.makeText(this, "camera permission denied", Toast.LENGTH_LONG).show();
        }
    }
}

count() function works with array. But if you want to count object's length then you can use this method.

$total = $obj->length;

The problem is not with extract, which can certainly handle 'military time'. It looks like you have a default timestamp format which has HH instead of HH24; or at least that's the only way I can see to recreate this:

SQL> select value from nls_session_parameters
  2  where parameter = 'NLS_TIMESTAMP_FORMAT';

VALUE
--------------------------------------------------------------------------------
DD-MON-RR HH24.MI.SSXFF

SQL> select extract(hour from cast(to_char(sysdate, 'DD-MON-YYYY HH24:MI:SS')
  2  as timestamp)) from dual;

EXTRACT(HOURFROMCAST(TO_CHAR(SYSDATE,'DD-MON-YYYYHH24:MI:SS')ASTIMESTAMP))
--------------------------------------------------------------------------
                                                                        15

alter session set nls_timestamp_format = 'DD-MON-YYYY HH:MI:SS';

Session altered.

SQL> select extract(hour from cast(to_char(sysdate, 'DD-MON-YYYY HH24:MI:SS')
  2  as timestamp)) from dual;

select extract(hour from cast(to_char(sysdate, 'DD-MON-YYYY HH24:MI:SS') as timestamp)) from dual
                              *
ERROR at line 1:
ORA-01849: hour must be between 1 and 12

So the simple 'fix' is to set the format to something that does recognise 24-hours:

SQL> alter session set nls_timestamp_format = 'DD-MON-YYYY HH24:MI:SS';

Session altered.

SQL> select extract(hour from cast(to_char(sysdate, 'DD-MON-YYYY HH24:MI:SS')
  2  as timestamp)) from dual;

EXTRACT(HOURFROMCAST(TO_CHAR(SYSDATE,'DD-MON-YYYYHH24:MI:SS')ASTIMESTAMP))
--------------------------------------------------------------------------
                                                                        15

Although you don't need the to_char at all:

SQL> select extract(hour from cast(sysdate as timestamp)) from dual;

EXTRACT(HOURFROMCAST(SYSDATEASTIMESTAMP))
-----------------------------------------
                                       15

its solved. Use nuget and search for the "ODP.NET, Managed Driver" invariant="Oracle.ManagedDataAccess.Client".

and install the package. it will resolve the issue for me.

It's easy, you should set server http response header first. The problem is not with your front-end javascript code. You need to return this header:

Access-Control-Allow-Origin:*

or

Access-Control-Allow-Origin:your domain

In Apache config files, the code is like this:

Header set Access-Control-Allow-Origin "*"

In nodejs,the code is like this:

res.setHeader('Access-Control-Allow-Origin','*');

you can use angular's filter https://docs.angularjs.org/api/ng/filter/filter

in your controller:

$filter('filter')(myArray, {'id':73}) 

or in your HTML

{{ myArray | filter : {'id':73} }}

public boolean compareMap(Map<String, String> map1, Map<String, String> map2) {

    if (map1 == null || map2 == null)
        return false;

    for (String ch1 : map1.keySet()) {
        if (!map1.get(ch1).equalsIgnoreCase(map2.get(ch1)))
            return false;

    }
    for (String ch2 : map2.keySet()) {
        if (!map2.get(ch2).equalsIgnoreCase(map1.get(ch2)))
            return false;

    }

    return true;
}

Floated elements don’t take up any vertical space in their containing element.

All of your elements inside #albumhold are floated, apart from #albumhead, which doesn’t look like it’d take up much space.

However, if you add overflow: hidden; to #albumhold (or some other CSS to clear floats inside it), it will expand its height to encompass its floated children.

I've had this issue a few times and to resolve I did the following:

1. Search through my C:\ drive for any file with the extension '.exd'
2. Delete those files (it is okay to do so)
3. Implement code that re-sizes the ActiveX objects each time the sheet is opened

I found this issue was caused everything we plugged the laptop into a projector and saved the file. Then everytime the issue came up I went just repeated steps 1. and 2. and my ActiveX objects were behaving again

Just in case anyone is insane like me and wants to just run typescript script as though it was a .js script, you can try this. I've written a hacky script that appears to execute the .ts script using node.

#!/usr/bin/env bash

NODEPATH="$HOME/.nvm/versions/node/v8.11.3/bin" # set path to your node/tsc

export TSC="$NODEPATH/tsc"
export NODE="$NODEPATH/node"

TSCFILE=$1 # only parameter is the name of the ts file you created.

function show_usage() {
    echo "ts2node [ts file]"
    exit 0
}

if [ "$TSCFILE" == "" ]
then
    show_usage;
fi

JSFILE="$(echo $TSCFILE|cut -d"." -f 1).js"

$TSC $TSCFILE && $NODE $JSFILE

You can do this or write your own but essentially, it creates the .js file and then uses node to run it like so:

# tsrun myscript.ts

Simple. Just make sure your script only has one "." else you'll need to change your JSFILE in a different way than what I've shown.

Stack

When a function or a method calls another function which in turns calls another function, etc., the execution of all those functions remains suspended until the very last function returns its value.

This chain of suspended function calls is the stack, because elements in the stack (function calls) depend on each other.

The stack is important to consider in exception handling and thread executions.

Heap

The heap is simply the memory used by programs to store variables. Element of the heap (variables) have no dependencies with each other and can always be accessed randomly at any time.

One thing that is really important to understand considering you have an XML file as :

<customer id="100">
    <Age>29</Age>
    <NAME>mkyong</NAME>
</customer>

I am sorry to inform you but :

@XmlElement
public void setAge(int age) {
    this.age = age;
}

will not help you, as it tries to look for "age" instead of "Age" element name from the XML.

I encourage you to manually specify the element name matching the one in the XML file :

@XmlElement(name="Age")
public void setAge(int age) {
    this.age = age;
}

And if you have for example :

@XmlRootElement
@XmlAccessorType (XmlAccessType.FIELD)
public class Customer {
...

It means it will use java beans by default, and at this time if you specify that you must not set another

@XmlElement(name="NAME")

annotation above a setter method for an element <NAME>..</NAME> it will fail saying that there cannot be two elements on one single variables.

I hope that it helps.

It depends on how often you insert or read. You can increase the array by more than one if needed.

numberOfItems = ??

' ...

If numberOfItems+1 >= arr.Length Then
    Array.Resize(arr, arr.Length + 10)
End If

arr(numberOfItems) = newItem
numberOfItems += 1

Also for A, you only need to get the array if needed.

Dim list As List(Of Integer)(arr) ' Do this only once, keep a reference to the list
                                  ' If you create a new List everything you add an item then this will never be fast

'...

list.Add(newItem)
arrayWasModified = True

' ...

Function GetArray()

    If arrayWasModified Then
        arr = list.ToArray()
    End If

    Return Arr
End Function

If you have the time, I suggest you convert it all to List and remove arrays.

* My code might not compile

Swift 2.0:

  var navArray:Array = (self.navigationController?.viewControllers)!
  navArray.removeAtIndex(navArray.count-2)
  self.navigationController?.viewControllers = navArray

It's actually possible to effectively define a variable that can be used in both the SELECT, WHERE and other clauses.

A cross join doesn't necessarily allow for appropriate binding to the referenced table columns, however OUTER APPLY does - and treats nulls more transparently.

SELECT
    vars.BalanceDue
FROM
    Entity e
OUTER APPLY (
    SELECT
        -- variables   
        BalanceDue = e.EntityTypeId,
        Variable2 = ...some..long..complex..expression..etc...
    ) vars
WHERE
    vars.BalanceDue > 0

Kudos to Syed Mehroz Alam.

pgBadger is another option - also listed here: https://github.com/dhamaniasad/awesome-postgres#utilities

Requires some additional setup in advance to capture the necessary data in the postgres logs though, see the official website.

Similar to @sirthomas's answer, JSON.NET also respects the EmitDefaultValue property on DataMemberAttribute:

[DataMember(Name="property_name", EmitDefaultValue=false)]

This may be desirable if you are already using [DataContract] and [DataMember] in your model type and don't want to add JSON.NET-specific attributes.

I'm using Batik for this. The complete Delphi code:

procedure ExecNewProcess(ProgramName : String; Wait: Boolean);
var
  StartInfo : TStartupInfo;
  ProcInfo : TProcessInformation;
  CreateOK : Boolean;
begin
  FillChar(StartInfo, SizeOf(TStartupInfo), #0);
  FillChar(ProcInfo, SizeOf(TProcessInformation), #0);
  StartInfo.cb := SizeOf(TStartupInfo);
  CreateOK := CreateProcess(nil, PChar(ProgramName), nil, nil, False,
              CREATE_NEW_PROCESS_GROUP + NORMAL_PRIORITY_CLASS,
              nil, nil, StartInfo, ProcInfo);
  if CreateOK then begin
    //may or may not be needed. Usually wait for child processes
    if Wait then
      WaitForSingleObject(ProcInfo.hProcess, INFINITE);
  end else
    ShowMessage('Unable to run ' + ProgramName);

  CloseHandle(ProcInfo.hProcess);
  CloseHandle(ProcInfo.hThread);
end;

procedure ConvertSVGtoPNG(aFilename: String);
const
  ExecLine = 'c:\windows\system32\java.exe -jar C:\Apps\batik-1.7\batik-rasterizer.jar ';
begin
  ExecNewProcess(ExecLine + aFilename, True);
end;

You can try the display:inline-block and :after.Like this:

HTML

<ul>
    <li><a href="">I would like this text centered vertically</a></li>
</ul>

CSS

li a {
    width: 300px;
    height: 100px;
    margin: auto 0;
    display: inline-block;
    vertical-align: middle;
    background: red;  
}
li a:after {
  content:"";
  display: inline-block;
  width: 1px solid transparent;
  height: 100%;
  vertical-align: middle;
}

Please view the demo.

Here's an example of code which uses the UTL_FILE.PUT and UTL_FILE.PUT_LINE calls:

declare 
  fHandle  UTL_FILE.FILE_TYPE;
begin
  fHandle := UTL_FILE.FOPEN('my_directory', 'test_file', 'w');

  UTL_FILE.PUT(fHandle, 'This is the first line');
  UTL_FILE.PUT(fHandle, 'This is the second line');
  UTL_FILE.PUT_LINE(fHandle, 'This is the third line');

  UTL_FILE.FCLOSE(fHandle);
EXCEPTION
  WHEN OTHERS THEN
    DBMS_OUTPUT.PUT_LINE('Exception: SQLCODE=' || SQLCODE || '  SQLERRM=' || SQLERRM);
    RAISE;
end;

The output from this looks like:

This is the first lineThis is the second lineThis is the third line

If you have more than one column to be converted you can do the following:

df[["col1", "col2", "col3"]] = df[["col1", "col2", "col3"]].apply(pd.to_datetime)

I was interested in this as well and came across some examples on the Spring Boot site.

   // get with query string parameters e.g. /system/resource?id="rtze1cd2"&person="sam smith" 
// so below the first query parameter id is the variable and name is the variable
// id is shown below as a RequestParam
    @GetMapping("/system/resource")
    // this is for swagger docs
    @ApiOperation(value = "Get the resource identified by id and person")
    ResponseEntity<?> getSomeResourceWithParameters(@RequestParam String id, @RequestParam("person") String name) {

        InterestingResource resource = getMyInterestingResourc(id, name);
        logger.info("Request to get an id of "+id+" with a name of person: "+name);

        return new ResponseEntity<Object>(resource, HttpStatus.OK);
    }

Update:

ngKeypress, ngKeydown and ngKeyup are now part of AngularJS.

<!-- you can, for example, specify an expression to evaluate -->
<input ng-keypress="count = count + 1" ng-init="count=0">

<!-- or call a controller/directive method and pass $event as parameter.
     With access to $event you can now do stuff like 
     finding which key was pressed -->
<input ng-keypress="changed($event)">

Earlier solutions:

Solution 1: Use ng-change with ng-model

<input type="text" placeholder="+639178983214" ng-model="mobileNumber" 
ng-controller="RegisterDataController" ng-change="keydown()">

JS:

function RegisterDataController($scope) {       
   $scope.keydown = function() {
        /* validate $scope.mobileNumber here*/
   };
}

Solution 2. Use $watch

<input type="text" placeholder="+639178983214" ng-model="mobileNumber" 
ng-controller="RegisterDataController">
    

JS:

$scope.$watch("mobileNumber", function(newValue, oldValue) {
    /* change noticed */
});

If you want to replace space below code worked for me in C#

Regex.Replace(Line,"\\\s","");

For Tab

Regex.Replace(Line,"\\\s\\\s","");

1. What exactly doesn't work?
2. Why are you using a 2d array?

3. If you must use a 2d array:

   int numOfPairs = 10;  String[][] array = new String[numOfPairs][2]; for(int i = 0; i < array.length; i++){     for(int j = 0; j < array[i].length; j++){         array[i] = new String[2];         array[i][0] = "original word";         array[i][1] = "rearranged word";     }    } 

Does this give you a hint?

Model = code for CRUD database operations.

Controller = responds to user actions, and passes the user requests for data retrieval or delete/update to the model, subject to the business rules specific to an organization. These business rules could be implemented in helper classes, or if they are not too complex, just directly in the controller actions. The controller finally asks the view to update itself so as to give feedback to the user in the form of a new display, or a message like 'updated, thanks', etc.,

View = UI that is generated based on a query on the model.

There are no hard and fast rules regarding where business rules should go. In some designs they go into model, whereas in others they are included with the controller. But I think it is better to keep them with the controller. Let the model worry only about database connectivity.

This works for me under Excel and a big JSON files using JSON query translated in to native form. https://github.com/VBA-tools/VBA-JSON I am able parse node like "item.something" and get value using simple command:

MsgBox Json("item")("something")

What's nice.

Add a $event to the ng-click, for example:

<button type="button" ng-click="saveOffer($event)" accesskey="S"></button>

Then the jQuery.Event was passed to the callback:
