this issue was driving me insane until i found this post which said to do

Open angular.json file and find budgets keyword.

It should look like:

    "budgets": [
       {
          "type": "initial",
          "maximumWarning": "2mb",
          "maximumError": "5mb"
       }
    ]

As you’ve probably guessed you can increase the maximumWarning value to prevent this warning, i.e.:

    "budgets": [
       {
          "type": "initial",
          "maximumWarning": "4mb", <===
          "maximumError": "5mb"
       }
    ]

What does budgets mean?

A performance budget is a group of limits to certain values that affect site performance, that may not be exceeded in the design and development of any web project.

In our case budget is the limit for bundle sizes.

By default, Elasticsearch installed goes into read-only mode when you have less than 5% of free disk space. If you see errors similar to this:

Elasticsearch::Transport::Transport::Errors::Forbidden: [403] {"error":{"root_cause":[{"type":"cluster_block_exception","reason":"blocked by: [FORBIDDEN/12/index read-only / allow delete (api)];"}],"type":"cluster_block_exception","reason":"blocked by: [FORBIDDEN/12/index read-only / allow delete (api)];"},"status":403}

Or in /usr/local/var/log/elasticsearch.log you can see logs similar to:

flood stage disk watermark [95%] exceeded on [nCxquc7PTxKvs6hLkfonvg][nCxquc7][/usr/local/var/lib/elasticsearch/nodes/0] free: 15.3gb[4.1%], all indices on this node will be marked read-only

Then you can fix it by running the following commands:

curl -XPUT -H "Content-Type: application/json" http://localhost:9200/_cluster/settings -d '{ "transient": { "cluster.routing.allocation.disk.threshold_enabled": false } }'
curl -XPUT -H "Content-Type: application/json" http://localhost:9200/_all/_settings -d '{"index.blocks.read_only_allow_delete": null}'

I know this has plenty of answers but since most of them are old (well, older), none is mentioning approach I grow very fond of really quick. In short:

Use functional components and hooks.

In longer:

Try to use as much functional components instead class ones especially for rendering, AND try to keep them as pure as possible (yes, data is dirty by default I know).

Two bluntly obvious benefits of functional components (there are more):

• Pureness or near pureness makes debugging so much easier
• Functional components remove the need for constructor boiler code

Quick proof for 2nd point - Isn't this absolutely disgusting?

constructor(props) {
        super(props);     
        this.toggle= this.toggle.bind(this);
        this.state = {
            details: false
        } 
    }  

If you are using functional components for more then rendering you are gonna need the second part of great duo - hooks. Why are they better then lifecycle methods, what else can they do and much more would take me a lot of space to cover so I recommend you to listen to the man himself: Dan preaching the hooks

In this case you need only two hooks:

A callback hook conveniently named useCallback. This way you are preventing the binding the function over and over when you re-render.

A state hook, called useState, for keeping the state despite entire component being function and executing in its entirety (yes, this is possible due to magic of hooks). Within that hook you will store the value of toggle.

If you read to this part you probably wanna see all I have talked about in action and applied to original problem. Here you go: Demo

For those of you that want only to glance the component and WTF is this about, here you are:

const Item = () => {

    // HOOKZ
  const [isVisible, setIsVisible] = React.useState('hidden');

  const toggle = React.useCallback(() => {
    setIsVisible(isVisible === 'visible' ? 'hidden': 'visible');
  }, [isVisible, setIsVisible]);

    // RENDER
  return (
  <React.Fragment>
    <div style={{visibility: isVisible}}>
        PLACEHOLDER MORE INFO
    </div>
    <button onClick={toggle}>Details</button>
  </React.Fragment>
  )
};

PS: I wrote this in case many people land here with similar problem. Hopefully, they will like what I have shown here, at least well enough to google it a bit more. This is NOT me saying other answers are wrong, this is me saying that since the time they have been written, there is another way (IMHO, a better one) of dealing with this.

OPTION 1: if you want to make a common utility function then you can use this

export function getCurrentDate(separator=''){

let newDate = new Date()
let date = newDate.getDate();
let month = newDate.getMonth() + 1;
let year = newDate.getFullYear();

return `${year}${separator}${month<10?`0${month}`:`${month}`}${separator}${date}`
}

and use it by just importing it as

import {getCurrentDate} from './utils'
console.log(getCurrentDate())

OPTION 2: or define and use in a class directly

getCurrentDate(separator=''){

let newDate = new Date()
let date = newDate.getDate();
let month = newDate.getMonth() + 1;
let year = newDate.getFullYear();

return `${year}${separator}${month<10?`0${month}`:`${month}`}${separator}${date}`
}

The existing answers solve most cases. However, I ran into a case where I needed the content of the grid-cell to be overflow: visible. I solved it by absolutely positioning within a wrapper (not ideal, but the best I know), like this:

.month-grid {
  display: grid;
  grid-template: repeat(6, 1fr) / repeat(7, 1fr);
  background: #fff;
  grid-gap: 2px;  
}

.day-item-wrapper {
  position: relative;
}

.day-item {
  position: absolute;
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
  padding: 10px;

  background: rgba(0,0,0,0.1);
}

yourTerminal:prompt> jupyter notebook --NotebookApp.iopub_data_rate_limit=1.0e10 

In my case Maximum call stack size exceeded was triggered by another error earlier. The logs looked like this:

I had to add --unsafe-perm to the install command and run it as root:

sudo npm install -g --unsafe-perm @aws-amplify/cli

The issue is caused by this:

.catch((error) => {
  assert.isNotOk(error,'Promise error');
  done();
});

If the assertion fails, it will throw an error. This error will cause done() never to get called, because the code errored out before it. That's what causes the timeout.

The "Unhandled promise rejection" is also caused by the failed assertion, because if an error is thrown in a catch() handler, and there isn't a subsequent catch() handler, the error will get swallowed (as explained in this article). The UnhandledPromiseRejectionWarning warning is alerting you to this fact.

In general, if you want to test promise-based code in Mocha, you should rely on the fact that Mocha itself can handle promises already. You shouldn't use done(), but instead, return a promise from your test. Mocha will then catch any errors itself.

Like this:

it('should transition with the correct event', () => {
  ...
  return new Promise((resolve, reject) => {
    ...
  }).then((state) => {
    assert(state.action === 'DONE', 'should change state');
  })
  .catch((error) => {
    assert.isNotOk(error,'Promise error');
  });
});

The following environment variable can be used:

NODE_OPTIONS= --max-old-space-size=8192 .

Another note: console.log() also consumes memory in the terminal.

just tried to comment the console.log() on terminal. because that will also take memory.

When your app references exceed 65,536 methods, you encounter a build error that indicates your app has reached the limit of the Android build architecture

Multidex support prior to Android 5.0

Versions of the platform prior to Android 5.0 (API level 21) use the Dalvik runtime for executing app code. By default, Dalvik limits apps to a single classes.dex bytecode file per APK. In order to get around this limitation, you can add the multidex support library to your project:

dependencies {
  implementation 'com.android.support:multidex:1.0.3'
}

Multidex support for Android 5.0 and higher

Android 5.0 (API level 21) and higher uses a runtime called ART which natively supports loading multiple DEX files from APK files. Therefore, if your minSdkVersion is 21 or higher, you do not need the multidex support library.

Avoid the 64K limit

• Remove unused code with ProGuard - Enable code shrinking

Configure multidex in app for

If your minSdkVersion is set to 21 or higher, all you need to do is set multiDexEnabled to true in your module-level build.gradle file

android {
defaultConfig {
    ...
    minSdkVersion 21 
    targetSdkVersion 28
    multiDexEnabled true
  }
 ...
}

if your minSdkVersion is set to 20 or lower, then you must use the multidex support library

android {
defaultConfig {
    ...
    minSdkVersion 15 
    targetSdkVersion 28
    multiDexEnabled true
   }
   ...
}

dependencies {
  compile 'com.android.support:multidex:1.0.3'
}

Override the Application class, change it to extend MultiDexApplication (if possible) as follows:

public class MyApplication extends MultiDexApplication { ... }

add to the manifest file

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.myapp">
    <application
            android:name="MyApplication" >
        ...
    </application>
</manifest>

I prefer to solve this in the classic way, creating a new array of my desired data type:

List<MyNewType> newArray = new ArrayList<>();
myOldArray.forEach(info -> newArray.add(objectMapper.convertValue(info, MyNewType.class)));

string is by default Nullable ,you don't need to do anything to make string Nullable

From react documentation : https://reactjs.org/blog/2018/06/07/you-probably-dont-need-derived-state.html

Erasing state when props change is an Anti Pattern

Since React 16, componentWillReceiveProps is deprecated. From react documentation, the recommended approach in this case is use

1. Fully controlled component: the ParentComponent of the ModalBody will own the start_time state. This is not my prefer approach in this case since i think the modal should own this state.
2. Fully uncontrolled component with a key: this is my prefer approach. An example from react documentation : https://codesandbox.io/s/6v1znlxyxn . You would fully own the start_time state from your ModalBody and use getInitialState just like you have already done. To reset the start_time state, you simply change the key from the ParentComponent

If you are simply testing a local dev version of WordPress as I was an hitting timeouts when WordPress tries to update itself you can always disable updates for your local version like so: https://www.wpbeginner.com/wp-tutorials/how-to-disable-automatic-updates-in-wordpress/

Don't do this for a production site!

The Maximum execution time of 30 seconds exceeded error is not related to Laravel but rather your PHP configuration.

Here is how you can fix it. The setting you will need to change is max_execution_time.

;;;;;;;;;;;;;;;;;;;
; Resource Limits ;
;;;;;;;;;;;;;;;;;;;

max_execution_time = 30     ; Maximum execution time of each script, in seconds
max_input_time = 60 ; Maximum amount of time each script may spend parsing request data
memory_limit = 8M      ; Maximum amount of memory a script may consume (8MB)

You can change the max_execution_time to 300 seconds like max_execution_time = 300

You can find the path of your PHP configuration file in the output of the phpinfo function in the Loaded Configuration File section.

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

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

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

In my case, the VS debugger was attached to the w3wp process. After detaching the debugger, I was able to restart the Application Pool

To answer your question, yes you may pass JSON in the URI as part of a GET request (provided you URL-encode). However, considering your reason for doing this is due to the length of the URI, using JSON will be self-defeating (introducing more characters than required).

I suggest you send your parameters in body of a POST request, either in regular CGI style (param1=val1&param2=val2) or JSON (parsed by your API upon receipt)

I recently ran into this problem because of my company's web content filter that uses its own Certificate Authority so that it can filter SSL traffic. PIP doesn't seem to be using the system's CA certificates in my case, producing the error you mention. Downgrading PIP to version 1.2.1 presented its own set of problems later on, so I went back to the original version that came with Python 3.4.

My workaround is quite simple: use easy_install. Either it doesn't check the certs (like the old PIP version), or it knows to use the system certs because it works every time for me and I can still use PIP to uninstall packages installed with easy_install.

If that doesn't work and you can get access to a network or computer that doesn't have the issue, you could always setup your own personal PyPI server: how to create local own pypi repository index without mirror?

I almost did that until I tried using easy_install as a last ditch effort.

I forced closed all Java.exe from taskmanger, restarted Android Studio and it worked for me

Okay, redis is pretty user friendly but there are some gotchas.

Here are just some easy commands for working with redis on Ubuntu:

install:

sudo apt-get install redis-server

start with conf:

sudo redis-server <path to conf>
sudo redis-server config/redis.conf

stop with conf:

redis-ctl shutdown

(not sure how this shuts down the pid specified in the conf. Redis must save the path to the pid somewhere on boot)

log:

tail -f /var/log/redis/redis-server.log

Also, various example confs floating around online and on this site were beyond useless. The best, sure fire way to get a compatible conf is to copy-paste the one your installation is already using. You should be able to find it here:

/etc/redis/redis.conf

Then paste it at <path to conf>, tweak as needed and you're good to go.

Just use requests' features:

import requests
from requests.adapters import HTTPAdapter
from requests.packages.urllib3.util.retry import Retry


session = requests.Session()
retry = Retry(connect=3, backoff_factor=0.5)
adapter = HTTPAdapter(max_retries=retry)
session.mount('http://', adapter)
session.mount('https://', adapter)

session.get(url)

This will GET the URL and retry 3 times in case of requests.exceptions.ConnectionError. backoff_factor will help to apply delays between attempts to avoid to fail again in case of periodic request quota.

Take a look at requests.packages.urllib3.util.retry.Retry, it has many options to simplify retries.

Is it a .sql file or is it compressed (.zip, .gz, etc)? Compressed formats sometimes require more PHP resources so you could try uncompressing it before uploading.

However, there are other methods you can try also. If you have command-line access, just upload the file and import with the command line client mysql (once at the mysql> prompt, use databasename; then source file.sql).

Otherwise you can use the phpMyAdmin "UploadDir" feature to put the file on the server and have it appear within phpMyAdmin without having to also upload it from your local machine.

This link has information on using UploadDir and this one has some more tips and methods.

This problem can be caused by requests for certain files that don't exist. For example, requests for files in wp-content/uploads/ where the file does not exist.

If this is the situation you're seeing, you can solve the problem by going to .htaccess and changing this line:

RewriteRule ^(wp-(content|admin|includes).*) $1 [L]

to:

RewriteRule ^(wp-(content|admin|includes).*) - [L]

The underlying issue is that the rule above triggers a rewrite to the exact same url with a slash in front and because there was a rewrite, the newly rewritten request goes back through the rules again and the same rule is triggered. By changing that line's "$1" to "-", no rewrite happens and so the rewriting process does not start over again with the same URL.

It's possible that there's a difference in how apache 2.2 and 2.4 handle this situation of only-difference-is-a-slash-in-front and that's why the default rules provided by WordPress aren't working perfectly.

Cause: A trigger was attempted to be retrieved for execution and was found to be invalid. This also means that compilation/authorization failed for the trigger.

Action: Options are to resolve the compilation/authorization errors, disable the trigger, or drop the trigger.

Syntax

ALTER TRIGGER trigger Name DISABLE;

ALTER TRIGGER trigger_Name ENABLE;

When I had this problem, I had literally just forgot to fill in a parameter value in the XAML of the code.

For some reason though, the exception would send me to the CS of the WPF program rather than the XAML. No idea why.

Browsers can't handle that many arguments. See this snippet for example:

alert.apply(window, new Array(1000000000));

This yields RangeError: Maximum call stack size exceeded which is the same as in your problem.

To solve that, do:

var arr = [];
for(var i = 0; i < 1000000; i++){
    arr.push(Math.random());
}

I think you are not configured properly,

if you are using XAMPP then you can easily send mail from localhost.

for example you can configure C:\xampp\php\php.ini and c:\xampp\sendmail\sendmail.ini for gmail to send mail.

in C:\xampp\php\php.ini find extension=php_openssl.dll and remove the semicolon from the beginning of that line to make SSL working for gmail for localhost.

in php.ini file find [mail function] and change

SMTP=smtp.gmail.com
smtp_port=587
sendmail_from = [email protected]
sendmail_path = "C:\xampp\sendmail\sendmail.exe -t"

(use the above send mail path only and it will work)

Now Open C:\xampp\sendmail\sendmail.ini. Replace all the existing code in sendmail.ini with following code

[sendmail]

smtp_server=smtp.gmail.com
smtp_port=587
error_logfile=error.log
debug_logfile=debug.log
[email protected]
auth_password=my-gmail-password
[email protected]

Now you have done!! create php file with mail function and send mail from localhost.

Update

First, make sure you PHP installation has SSL support (look for an "openssl" section in the output from phpinfo()).

You can set the following settings in your PHP.ini:

ini_set("SMTP","ssl://smtp.gmail.com");
ini_set("smtp_port","465");

np.where function works as follows:

df['X'] = np.where(df['Y']>=50, 'yes', 'no')

In your case you would want:

import numpy as np
df['my_channel'] = np.where(df.my_channel > 20000, 0, df.my_channel)

Yes it should be fixed, HAXM isn't working.

HAXM sometimes works; experience with HAXM is currently sporadic across platforms.

For instance, I've got late 2009 iMac running 10.8.5 and i7 processor @2.8Ghz, Android SDK 22.6 with all the goodies updated this morning (03/05/14). API17 will build emulators with HAXM acceleration on this iMac machine, API19 chokes out.

I also have early 2013 MBP 15" Retina running 10.8.5 and i7 processor @2.7Ghz, Android SDK 22.6 with all the goodies updated this morning (03/05/14). API17 will build emulators with HAXM acceleration, API19 works great too.

Ditto for my (personal) late 2013 MBP Retina 13" with dual-core i5 and Mavericks.

There is something going on for virtualization at the chip level missing from older CPU's (even i7's) that the new API19 x86 images need for HAXM to work. If API19 is not working, give API17 or even 16 a try.

I found a dirty solution:

/bin/bash -c "ulimit -s 65500; exec /usr/local/bin/node --stack-size=65500 /path/to/app.js"

It just increase call stack limit. I think that this is not suitable for production code, but I needed it for script that run only once.

Actually it happens when the number of processes exceeds the limits set by the hosting provider.

To avoid either we need to enhance the capacity by hosting providers or we need to check in the code whether any process takes longer time (like background tasks).

How to change max_connections

You can change max_connections while MySQL is running via SET:

mysql> SET GLOBAL max_connections = 5000;
Query OK, 0 rows affected (0.00 sec)

mysql> SHOW VARIABLES LIKE "max_connections";
+-----------------+-------+
| Variable_name   | Value |
+-----------------+-------+
| max_connections | 5000  |
+-----------------+-------+
1 row in set (0.00 sec)

To OP

timeout related

I had never seen your error message before, so I googled. probably, you are using Connector/Net. Connector/Net Manual says there is max connection pool size. (default is 100) see table 22.21.

I suggest that you increase this value to 100k or disable connection pooling Pooling=false

UPDATED

he has two questions.

Q1 - what happens if I disable pooling Slow down making DB connection. connection pooling is a mechanism that use already made DB connection. cost of Making new connection is high. http://en.wikipedia.org/wiki/Connection_pool

Q2 - Can the value of pooling be increased or the maximum is 100?

you can increase but I'm sure what is MAX value, maybe max_connections in my.cnf

My suggestion is that do not turn off Pooling, increase value by 100 until there is no connection error.

Wish it helps.

I found squashing more useful than filter-branch. I did the following:

1. Locally delete large files.
2. Commit the local deletes.
3. Soft reset back X number of commits (for me it was 3): git reset --soft HEAD~3.
4. Then recommit all the changes together (AKA squash) git commit -m "New message for the combined commit"
5. Push squashed commit.

Special case (from user @lituo): If above doesn't work, then you may have this case. Commit 1 included the large file and Commit 1's push failed due to large file error. Commit 2 removed the large file by git rm --cached [file_name] but Commit 2's push still failed. You can follow the same steps above but instead of using HEAD~3, use HEAD~2.

One thing you can do is, you might have subfolders for each projects. So, install mongoose in that subfolders and require() mongoose from own folders in each sub applications. Not from the project root or from global. So one sub project, one mongoose installation and one mongoose instance.

-app_root/
--foo_app/
---db_access.js
---foo_db_connect.js
---node_modules/
----mongoose/
--bar_app/
---db_access.js
---bar_db_connect.js
---node_modules/
----mongoose/

In foo_db_connect.js

var mongoose = require('mongoose');
mongoose.connect('mongodb://localhost/foo_db');
module.exports = exports = mongoose;

In bar_db_connect.js

var mongoose = require('mongoose');
mongoose.connect('mongodb://localhost/bar_db');
module.exports = exports = mongoose;

In db_access.js files

var mongoose = require("./foo_db_connect.js"); // bar_db_connect.js for bar app

Now, you can access multiple databases with mongoose.

Try this on your position:fixed element.

A full example with Zebra_Image library, that I think is so easy and useful. There are a lot of code, but if you read it, there are a lot of comments too so you can make copy and paste to use it quickly.

This example validates image format, size and replace image size with custom resolution. There is Zebra library and documentation (download only Zebra_Image.php file).

Explanation:

1. An image is uploaded to server by uploadFile function.
2. If image has been uploaded correctly, we recover this image and its path by getUserFile function.
3. Resize image to custom width and height and replace at same path.

Main function

private function uploadImage() {        
    $target_file = "../img/blog/";
    
//this function could be in the same PHP file or class. I use a Helper (see bellow)
    if(UsersUtils::uploadFile($target_file, $this->selectedBlog->getId())) {
//This function is at same Helper class.
//The image will be returned allways if there isn't errors uploading it, for this reason there aren't validations here.
        $blogPhotoPath = UsersUtils::getUserFile($target_file, $this->selectedBlog->getId());
        
        // create a new instance of the class
        $imageHelper = new Zebra_Image();
        // indicate a source image
        $imageHelper->source_path = $blogPhotoPath;
        // indicate a target image
        $imageHelper->target_path = $blogPhotoPath;
        // since in this example we're going to have a jpeg file, let's set the output
        // image's quality
        $imageHelper->jpeg_quality = 100;

        // some additional properties that can be set
        // read about them in the documentation
        $imageHelper->preserve_aspect_ratio = true;
        $imageHelper->enlarge_smaller_images = true;
        $imageHelper->preserve_time = true;
        $imageHelper->handle_exif_orientation_tag = true;
        // resize
        // and if there is an error, show the error message
        if (!$imageHelper->resize(450, 310, ZEBRA_IMAGE_CROP_CENTER)) {

External functions or use at same PHP file removing public static qualifiers.

Set overflow-y property to auto, or remove the property altogether if it is not inherited.

I have come to point out the answer nobody seems to see here. You can fullfill all requests you have made with pure CSS and it's very simple. Just use Media Queries. Media queries can check the orientation of the user's screen, or viewport. Then you can style your images depending on the orientation.

Just set your default CSS on your images like so:

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

Then use some media queries to check your orientation and that's it!

@media (orientation: landscape) { img { height:100%; } }
@media (orientation: portrait) { img { width:100%; } }

You will always get an image that scales to fit the screen, never loses aspect ratio, never scales larger than the screen, never clips or overflows.

To learn more about these media queries, you can read MDN's specs.

Centering

To center your image horizontally and vertically, just use the flex box model. Use a parent div set to 100% width and height, like so:

div.parent {
   display:flex;
   position:fixed;
   left:0px;
   top:0px;
   width:100%;
   height:100%;
   justify-content:center;
   align-items:center;
}

With the parent div's display set to flex, the element is now ready to use the flex box model. The justify-content property sets the horizontal alignment of the flex items. The align-items property sets the vertical alignment of the flex items.

Conclusion

I too had wanted these exact requirements and had scoured the web for a pure CSS solution. Since none of the answers here fulfilled all of your requirements, either with workarounds or settling upon sacrificing a requirement or two, this solution really is the most straightforward for your goals; as it fulfills all of your requirements with pure CSS.

EDIT: The accepted answer will only appear to work if your images are large. Try using small images and you will see that they can never be larger than their original size.

Expanding on @Finik's excellent answer, this fix is only applied to non-mobile devices. I tested in IE8, Chrome, and Firefox 22 - it works with very long or short content.

.modal {
  text-align: center;
}
@media screen and (min-device-width: 768px) {
  .modal:before {
    display: inline-block;
    vertical-align: middle;
    content: " ";
    height: 100%;
  }
}

.modal-dialog {
  display: inline-block;
  text-align: left;
  vertical-align: middle;
}

sample code:

<em><b>
<h2>Upload,Save and Download video </h2>
<form method="POST" action="" enctype="multipart/form-data">
<input type="file" name="video"/>
<input type="submit" name="submit" value="Upload"/></b>
</form></em>

<?php>
include("connect.php");
$errors=1;
//Targeting Folder
$target="videos/";
if(isset($_POST['submit'])){
//Targeting Folder 
$target=$target.basename($_FILES['video']['name']);
//Getting Selected video Type
$type=pathinfo($target,PATHINFO_EXTENSION);
 //Allow Certain File Format To Upload
 if($type!='mp4' && $type!='3gp' && $type!='avi'){
  echo "Only mp4,3gp,avi file format are allowed to Upload";
  $errors=0;
 }
 //checking for Exsisting video Files
  if(file_exists($target)){
   echo "File Exist";
   $errors=0;
   }
  $filesize=$_FILES['video']['size'];
  if($filesize>250*2000000){
  echo 'You Can not Upload Large File(more than 500MB) by Default ini setting..<a     href="http://www.codenair.com/2018/03/how-to-upload-large-file-in-php.html">How to   upload large file in php</a>'; 
    $errors=0;
    }
   if($errors == 0){
   echo ' Your File Not Uploaded';
    }else{
 //Moving The video file to Desired Directory
  $uplaod_success=move_uploaded_file($_FILES['video']['tmp_name'],$target);
  if($uplaod_success){
  //Getting Selected video Information
    $name=$_FILES['video']['name'];
    $size=$_FILES['video']['size'];
    $result=mysqli_query($con,"INSERT INTO VIdeos           (name,size,type)VALUES('".$name."','".$size."','".$type."')");
    if($result==TRUE){
    echo "Your video '$name' Successfully Upload and Information Saved Our  Database";
    }
   }
  }

Killing the vstest.executionengine.exe process(es) resolves this issue 90% of the time for me. If that doesn't work, then also killing QTAgent32.exe and then deleting the /bin and /obj folders for the project in question works.

This is the most irritating part of my work day. :)

The best way to use is white-space: nowrap; This will align the text to one line.

If all above fail, try setting the following properties for your input, to have it take max space but not overflow:

input {
    min-width: 100%;
    max-width: 100%;
}

Wrap all the children inside of another LinearLayout with wrap_content for both the width and the height as well as the vertical orientation.

Your calls are made recursively which pushes functions on to the stack infinitely that causes max call stack exceeded error due to recursive behavior. Instead try using setTimeout which is a callback.

Also based on your markup your selector is wrong. it should be #advisersDiv

Demo

function fadeIn() {
    $('#pulseDiv').find('div#advisersDiv').delay(400).addClass("pulse");
    setTimeout(fadeOut,1); //<-- Provide any delay here
};

function fadeOut() {
    $('#pulseDiv').find('div#advisersDiv').delay(400).removeClass("pulse");
    setTimeout(fadeIn,1);//<-- Provide any delay here
};
fadeIn();

RUn the following query to find if you are running spfile or not:

SELECT DECODE(value, NULL, 'PFILE', 'SPFILE') "Init File Type" 
       FROM sys.v_$parameter WHERE name = 'spfile';

If the result is "SPFILE", then use the following command:

alter system set open_cursors = 4000 scope=both; --4000 is the number of open cursor

if the result is "PFILE", then use the following command:

alter system set open_cursors = 1000 ;

You can read about SPFILE vs PFILE here,

http://www.orafaq.com/node/5

I find that the "solution" of just increasing the timeouts obscures what's really going on here, which is either

1. Your code and/or network calls are way too slow (should be sub 100 ms for a good user experience)
2. The assertions (tests) are failing and something is swallowing the errors before Mocha is able to act on them.

You usually encounter #2 when Mocha doesn't receive assertion errors from a callback. This is caused by some other code swallowing the exception further up the stack. The right way of dealing with this is to fix the code and not swallow the error.

When external code swallows your errors

In case it's a library function that you are unable to modify, you need to catch the assertion error and pass it onto Mocha yourself. You do this by wrapping your assertion callback in a try/catch block and pass any exceptions to the done handler.

it('should not fail', function (done) { // Pass reference here!

  i_swallow_errors(function (err, result) {
    try { // boilerplate to be able to get the assert failures
      assert.ok(true);
      assert.equal(result, 'bar');
      done();
    } catch (error) {
      done(error);
    }
  });
});

This boilerplate can of course be extracted into some utility function to make the test a little more pleasing to the eye:

it('should not fail', function (done) { // Pass reference here!
    i_swallow_errors(handleError(done, function (err, result) {
        assert.equal(result, 'bar');
    }));
});

// reusable boilerplate to be able to get the assert failures
function handleError(done, fn) {
    try { 
        fn();
        done();
    } catch (error) {
        done(error);
    }
}

Speeding up network tests

Other than that I suggest you pick up the advice on starting to use test stubs for network calls to make tests pass without having to rely on a functioning network. Using Mocha, Chai and Sinon the tests might look something like this

describe('api tests normally involving network calls', function() {

    beforeEach: function () {
        this.xhr = sinon.useFakeXMLHttpRequest();
        var requests = this.requests = [];

        this.xhr.onCreate = function (xhr) {
            requests.push(xhr);
        };
    },

    afterEach: function () {
        this.xhr.restore();
    }


    it("should fetch comments from server", function () {
        var callback = sinon.spy();
        myLib.getCommentsFor("/some/article", callback);
        assertEquals(1, this.requests.length);

        this.requests[0].respond(200, { "Content-Type": "application/json" },
                                 '[{ "id": 12, "comment": "Hey there" }]');
        expect(callback.calledWith([{ id: 12, comment: "Hey there" }])).to.be.true;
    });

});

See Sinon's nise docs for more info.

I was also interested in this and I've compared all the suggested answers with perfplot. (Disclaimer: I'm the author of perfplot.)

If you know that the array you're looking through is already sorted, then

numpy.searchsorted(a, alpha)

is for you. It's O(log(n)) operation, i.e., the speed hardly depends on the size of the array. You can't get faster than that.

If you don't know anything about your array, you're not going wrong with

numpy.argmax(a > alpha)

Already sorted:

Unsorted:

Code to reproduce the plot:

import numpy
import perfplot


alpha = 0.5
numpy.random.seed(0)


def argmax(data):
    return numpy.argmax(data > alpha)


def where(data):
    return numpy.where(data > alpha)[0][0]


def nonzero(data):
    return numpy.nonzero(data > alpha)[0][0]


def searchsorted(data):
    return numpy.searchsorted(data, alpha)


perfplot.save(
    "out.png",
    # setup=numpy.random.rand,
    setup=lambda n: numpy.sort(numpy.random.rand(n)),
    kernels=[argmax, where, nonzero, searchsorted],
    n_range=[2 ** k for k in range(2, 23)],
    xlabel="len(array)",
)

"Am i doing it right?Is there better/smarter way to achieve the output this code gave me?"

Generally speaking, yes, you're doing it right. Tkinter has no native scrollable container other than the canvas. As you can see, it's really not that difficult to set up. As your example shows, it only takes 5 or 6 lines of code to make it work -- depending on how you count lines.

"Why must i use grid method?(i tried place method, but none of the labels appear on the canvas?)"

You ask about why you must use grid. There is no requirement to use grid. Place, grid and pack can all be used. It's simply that some are more naturally suited to particular types of problems. In this case it looks like you're creating an actual grid -- rows and columns of labels -- so grid is the natural choice.

"What so special about using anchor='nw' when creating window on canvas?"

The anchor tells you what part of the window is positioned at the coordinates you give. By default, the center of the window will be placed at the coordinate. In the case of your code above, you want the upper left ("northwest") corner to be at the coordinate.

Latitude maximum in total is: 9 (12.3456789), longitude 10 (123.4567890), they both have maximum 7 decimals chars (At least is what i can find in Google Maps),

For example, both columns in Rails and Postgresql looks something like this:

t.decimal :latitude, precision: 9, scale: 7
t.decimal :longitude, precision: 10, scale: 7

i solved this by http://willcodeforcoffee.com/2007/01/31/cakephp-error-500-too-many-redirects/ just uncomment or add this:

RewriteBase /
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ index.php?url=$1 [QSA,L]

to your .htaccess file

I had the same problem when and I solved it by using the following annotation :

@EnableAutoConfiguration(exclude = {
        SecurityAutoConfiguration.class
})
public class Application {...}

I think the behavior is the same as what Abhishek explained

A cleaner way to gain higher control might be to package the retry stuff into a function and make that function retriable using a decorator and whitelist the exceptions.

I have created the same here: http://www.praddy.in/retry-decorator-whitelisted-exceptions/

Reproducing the code in that link :

def retry(exceptions, delay=0, times=2):
"""
A decorator for retrying a function call with a specified delay in case of a set of exceptions

Parameter List
-------------
:param exceptions:  A tuple of all exceptions that need to be caught for retry
                                    e.g. retry(exception_list = (Timeout, Readtimeout))
:param delay: Amount of delay (seconds) needed between successive retries.
:param times: no of times the function should be retried


"""
def outer_wrapper(function):
    @functools.wraps(function)
    def inner_wrapper(*args, **kwargs):
        final_excep = None  
        for counter in xrange(times):
            if counter > 0:
                time.sleep(delay)
            final_excep = None
            try:
                value = function(*args, **kwargs)
                return value
            except (exceptions) as e:
                final_excep = e
                pass #or log it

        if final_excep is not None:
            raise final_excep
    return inner_wrapper

return outer_wrapper

@retry(exceptions=(TimeoutError, ConnectTimeoutError), delay=0, times=3)

There are many different things you can do when dealing with responsive tables.

I personally like this approach by Chris Coyier:

• http://css-tricks.com/responsive-data-tables/

You can find many other alternatives here:

• http://css-tricks.com/responsive-data-table-roundup/
• http://bradfrost.github.io/this-is-responsive/patterns.html#tables

If you can leverage Bootstrap and get something quickly, you can simply use the class names ".hidden-phone" and ".hidden-tablet" to hide some rows but this approach might to be the best in many cases. More info (see "Responsive utility classes"):

Don't use it if not supported and to check support just call this function

sharing in Es6 full read and write localStorage Example with support check

const LOCAL_STORAGE_KEY = 'tds_app_localdata';

const isSupported = () => {
  try {
    localStorage.setItem('supported', '1');
    localStorage.removeItem('supported');
    return true;
  } catch (error) {
    return false;
  }
};


const writeToLocalStorage =
  components =>
    (isSupported ?
      localStorage.setItem(LOCAL_STORAGE_KEY, JSON.stringify(components))
      : components);

const isEmpty = component => (!component || Object.keys(component).length === 0);

const readFromLocalStorage =
  () => (isSupported ? JSON.parse(localStorage.getItem(LOCAL_STORAGE_KEY)) || {} : null);

This will make sure your keys are set and retrieved properly on all browsers.

I've changed the recursion to iteration.

def MovingTheBall(listOfBalls,position,numCell):
while 1:
    stop=1
    positionTmp = (position[0]+choice([-1,0,1]),position[1]+choice([-1,0,1]),0)
    for i in range(0,len(listOfBalls)):
        if positionTmp==listOfBalls[i].pos:
            stop=0
    if stop==1:
        if (positionTmp[0]==0 or positionTmp[0]>=numCell or positionTmp[0]<=-numCell or positionTmp[1]>=numCell or positionTmp[1]<=-numCell):
            stop=0
        else:
            return positionTmp

Works good :D

You need to set basicHttpBinding -> MaxReceivedMessageSize in the client configuration.

Ok I have found a solution. The problem is that the site uses SSLv3. And I know that there are some problems in the openssl module. Some time ago I had the same problem with the SSL versions.

<?php
function getSSLPage($url) {
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_HEADER, false);
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_SSLVERSION,3); 
    $result = curl_exec($ch);
    curl_close($ch);
    return $result;
}

var_dump(getSSLPage("https://eresearch.fidelity.com/eresearch/evaluate/analystsOpinionsReport.jhtml?symbols=api"));

When you set the SSL Version with curl to v3 then it works.

Edit:

Another problem under Windows is that you don't have access to the certificates. So put the root certificates directly to curl.

http://curl.haxx.se/docs/caextract.html

here you can download the root certificates.

curl_setopt($ch, CURLOPT_CAINFO, __DIR__ . "/certs/cacert.pem");
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, true);

Then you can use the CURLOPT_SSL_VERIFYPEER option with true otherwise you get an error.

Not a lot to go on there, but I think what you're looking for is to flip the width and max-width values:

#container2 {
  width: 90%;
  max-width: 960px;
  /* etc, etc... */
}

That'll give you a container that's 90% of the width of the available space, up to a maximum of 960px, but that's dependent on its container being resizable itself. Responsive design is a whole big ball of wax though, so this doesn't even scratch the surface.

query to find sql that opened.

SELECT s.machine, oc.user_name, oc.sql_text, count(1) 
FROM v$open_cursor oc, v$session s
WHERE oc.sid = s.sid
and S.USERNAME='XXXX'
GROUP BY user_name, sql_text, machine
HAVING COUNT(1) > 2
ORDER BY count(1) DESC

Check the php.ini

ini_set('max_execution_time', 300); //300 seconds = 5 minutes

ini_set('max_execution_time', 0); //0=NOLIMIT

You also need the change post-max-size.

So for us it was we were trying to send too large of an object through our AIDL interface to a remote service. The transaction size cannot exceed 1MB. The request is broken down into separate chunks of 512KB and sent one at a time through the interface. A brutal solution I know but hey - its Android :(

i think the main things to remember about parsing csv is that it follows some simple rules:

a)it's a text file so easily opened b) each row is determined by a line end \n so split the string into lines first c) each row/line has columns determined by a comma so split each line by that to get an array of columns

have a read of this post to see what i am talking about

it's actually very easy to do once you have the hang of it and becomes very useful.

Use the --force (-f) flag on your mysql import. Rather than stopping on the offending statement, MySQL will continue and just log the errors to the console.

For example:

mysql -u userName -p -f -D dbName < script.sql

To make life easier when entering multiple dates/times it is possible to use a custom format to remove the need to enter the colon, and the leading "hour" 0. This however requires a second field for the numerical date to be stored, as the displayed date from the custom format is in base 10.

Displaying a number as a time (no need to enter colons, but no time conversion)

For displaying the times on the sheet, and for entering them without having to type the colon set the cell format to custom and use:

0/:00

Then enter your time. For example, if you wanted to enter 62:30, then you would simply type 6230 and your custom format would visually insert a colon 2 decimal points from the right.

If you only need to display the times, stop here.

Converting number to time

If you need to be able to calculate with the times, you will need to convert them from base 10 into the time format.

This can be done with the following formula (change A2 to the relevant cell reference):

=TIME(0,TRUNC(A2/100),MOD(A2,100))

• =TIME starts the number to time conversion
• We don't need hours, so enter 0, at the beginning of the formula, as the format is always hh,mm,ss (to display hours and minutes instead of minutes and seconds, place the 0 at the end of the formula).
• For the minutes, TRUNC(A2/100), discards the rightmost 2 digits.
• For the seconds, MOD(A2,100) keeps the rightmost 2 digits and discards everything to the left.

The above formula was found and adapted from this article: PC Mag.com - Easy Date and Time Entry in Excel

Alternatively, you could skip the 0/:00 custom formatting, and just enter your time in a cell to be referenced of the edge of the visible workspace or on another sheet as you would for the custom formatting (ie: 6230 for 62:30)

Then change the display format of the cells with the formula to [m]:ss as @Sean Chessire suggested.

Here is a screen shot to show what I mean.

pandas provides high level data manipulation tools built on top of NumPy. NumPy by itself is a fairly low-level tool, similar to MATLAB. pandas on the other hand provides rich time series functionality, data alignment, NA-friendly statistics, groupby, merge and join methods, and lots of other conveniences. It has become very popular in recent years in financial applications. I will have a chapter dedicated to financial data analysis using pandas in my upcoming book.

I had similar issue, I resolved by changing the requestlimits maxAllowedContentLength ="40000000" section of applicationhost.config file, located in "C:\Windows\System32\inetsrv\config" directory

Look for security Section and add the sectionGroup.

<sectionGroup name="requestfiltering">
    <section name="requestlimits" maxAllowedContentLength ="40000000" />
</sectionGroup>

*NOTE delete;

<section name="requestfiltering" overrideModeDefault="Deny" />

From http://codecorner.galanter.net/2012/06/04/solution-for-operation-is-not-valid-due-to-the-current-state-of-the-object-error/

Issue happens because Microsoft Security Update MS11-100 limits number of keys in Forms collection during HTTP POST request. To alleviate this problem you need to increase that number.

This can be done in your application Web.Config in the <appSettings> section (create the section directly under <configuration> if it doesn’t exist). Add 2 lines similar to the lines below to the section:

<add key="aspnet:MaxHttpCollectionKeys" value="2000" />
<add key="aspnet:MaxJsonDeserializerMembers" value="2000" />

The above example set the limit to 2000 keys. This will lift the limitation and the error should go away.

This one might works for you....

void List<Integer> makeSequence(int begin, int end) {

  AtomicInteger ai=new AtomicInteger(begin);
  List<Integer> ret = new ArrayList(end-begin+1);

  while ( end-->begin) {

    ret.add(ai.getAndIncrement());

  }
  return ret;  
}

This happens when a python extension (written in C) tries to access a memory beyond reach.

You can trace it in following ways.

• Add sys.settrace at the very first line of the code.

• Use gdb as described by Mark in this answer.. At the command prompt

  gdb python
  (gdb) run /path/to/script.py
  ## wait for segfault ##
  (gdb) backtrace
  ## stack trace of the c code
  

Essentially you want to add code to the Calculate event of the relevant Worksheet.

In the Project window of the VBA editor, double-click the sheet you want to add code to and from the drop-downs at the top of the editor window, choose 'Worksheet' and 'Calculate' on the left and right respectively.

Alternatively, copy the code below into the editor of the sheet you want to use:

Private Sub Worksheet_Calculate()

If Sheets("MySheet").Range("A1").Value > 0.5 Then
    MsgBox "Over 50%!", vbOKOnly
End If

End Sub

This way, every time the worksheet recalculates it will check to see if the value is > 0.5 or 50%.

Indentation when using a block can cause this error and is very hard to find.

if [ ! -d /var/lib/mysql/mysql ]; then
   /usr/bin/mysql --protocol=socket --user root << EOSQL
        SET @@SESSION.SQL_LOG_BIN=0;
        CREATE USER 'root'@'%';
   EOSQL
fi

=> Example above will cause an error because EOSQL is indented. Remove indentation as shown below. Posting this because it took me over an hour to figure out the error.

if [ ! -d /var/lib/mysql/mysql ]; then
   /usr/bin/mysql --protocol=socket --user root << EOSQL
        SET @@SESSION.SQL_LOG_BIN=0;
        CREATE USER 'root'@'%';
EOSQL
fi

Method 1

Word boundaries would work perfectly here, such as with:

\b\w{3,8}\b
\b\w{2,}
\b\w{,10}\b
\b\w{5}\b

RegEx Demo 1

Java

Some languages such as Java and C++ are double-escape required:

\\b\\w{3,8}\\b
\\b\\w{2,}
\\b\\w{,10}\\b
\\b\\w{5}\\b

^{PS: \\b\\w{,10}\\b may not work for all languages or flavors.}

Test 1

import java.util.regex.Matcher;
import java.util.regex.Pattern;


public class RegularExpression{

    public static void main(String[] args){


        final String regex = "\\b\\w{3,8}\\b";
        final String string = "words with length three to eight";

        final Pattern pattern = Pattern.compile(regex, Pattern.MULTILINE);
        final Matcher matcher = pattern.matcher(string);

        while (matcher.find()) {
            System.out.println("Full match: " + matcher.group(0));
        }

    }
}

Output 1

Full match: words
Full match: with
Full match: length
Full match: three
Full match: eight

Method 2

Another good-to-know method is to use negative lookarounds:

(?<!\w)\w{3,8}(?!\w)
(?<!\w)\w{2,}
(?<!\w)\w{,10}(?!\w)
(?<!\w)\w{5}(?!\w)

Java

(?<!\\w)\\w{3,8}(?!\\w)
(?<!\\w)\\w{2,}
(?<!\\w)\\w{,10}(?!\\w)
(?<!\\w)\\w{5}(?!\\w)

RegEx Demo 2

Test 2

import java.util.regex.Matcher;
import java.util.regex.Pattern;


public class RegularExpression{

    public static void main(String[] args){


        final String regex = "(?<!\\w)\\w{1,10}(?!\\w)";
        final String string = "words with length three to eight";

        final Pattern pattern = Pattern.compile(regex, Pattern.MULTILINE);
        final Matcher matcher = pattern.matcher(string);

        while (matcher.find()) {
            System.out.println("Full match: " + matcher.group(0));
        }

    }
}

Output 2

Full match: words
Full match: with
Full match: length
Full match: three
Full match: to
Full match: eight

there are many causes such as

• The network link between server and client may be temporarily going down.
• running out of system resources.
• sending malformed data.

Here is the Kotlin solution

One line,

if (yourString?.length!! >= 10) yourString?.take(90).plus("...") else yourString

Traditional,

if (yourString?.length!! >= 10) {
  yourString?.take(10).plus("...")
 } else {
  yourString
 }

You can also use String.format("%3.3s", "abcdefgh"). The first digit is the minimum length (the string will be left padded if it's shorter), the second digit is the maxiumum length and the string will be truncated if it's longer. So

System.out.printf("'%3.3s' '%3.3s'", "abcdefgh", "a");

will produce

'abc' '  a'

(you can remove quotes, obviously).

I use the code to increase the default limit globally: require('events').EventEmitter.prototype._maxListeners = 100;

To prevent this, make sure every BEGIN TRANSACTION has COMMIT

The following will say successful but will leave uncommitted transactions:

BEGIN TRANSACTION
BEGIN TRANSACTION
<SQL_CODE?
COMMIT

Closing query windows with uncommitted transactions will prompt you to commit your transactions. This will generally resolve the Error 1222 message.

You can increment the stack depth allowed - with this, deeper recursive calls will be possible, like this:

import sys
sys.setrecursionlimit(10000) # 10000 is an example, try with different values

... But I'd advise you to first try to optimize your code, for instance, using iteration instead of recursion.

When an unauthorized request comes in, the entire request is URL encoded, and added as a query string to the request to the authorization form, so I can see where this may result in a problem given your situation.

According to MSDN, the correct element to modify to reset maxQueryStringLength in web.config is the <httpRuntime> element inside the <system.web> element, see httpRuntime Element (ASP.NET Settings Schema). Try modifying that element.

you'll want to use && to see that it is not equal to "AM" AND not equal to "PM"

if(!TimeOfDayStringQ.equals("AM") && !TimeOfDayStringQ.equals("PM")) {
    System.out.println("Sorry, incorrect input.");
    System.exit(1);
}

to be clear you can also do

if(!(TimeOfDayStringQ.equals("AM") || TimeOfDayStringQ.equals("PM"))){
    System.out.println("Sorry, incorrect input.");
    System.exit(1);
}

to have the not (one or the other) phrase in the code (remember the (silent) brackets)

This is the the right answer:

go to

c:\wamp\apps\phpmyadmin3.4.10.1\libraries\config.default.php

find and set

$cfg['ExecTimeLimit'] = 0;

restart all services and done.

There are many ways to check the size, but as a developer we dont have much access to query meta tables, I find this solution very easy (Note: if you are getting error message ORA-01653 ‘The ORA-01653 error is caused because you need to add space to a tablespace.’)

--Size of All Table Space

--1. Used Space
SELECT TABLESPACE_NAME,TO_CHAR(SUM(NVL(BYTES,0))/1024/1024/1024, '99,999,990.99') AS "USED SPACE(IN GB)" FROM USER_SEGMENTS GROUP BY TABLESPACE_NAME
--2. Free Space
SELECT TABLESPACE_NAME,TO_CHAR(SUM(NVL(BYTES,0))/1024/1024/1024, '99,999,990.99') AS "FREE SPACE(IN GB)" FROM   USER_FREE_SPACE GROUP BY TABLESPACE_NAME

--3. Both Free & Used
SELECT USED.TABLESPACE_NAME, USED.USED_BYTES AS "USED SPACE(IN GB)",  FREE.FREE_BYTES AS "FREE SPACE(IN GB)"
FROM
(SELECT TABLESPACE_NAME,TO_CHAR(SUM(NVL(BYTES,0))/1024/1024/1024, '99,999,990.99') AS USED_BYTES FROM USER_SEGMENTS GROUP BY TABLESPACE_NAME) USED
INNER JOIN
(SELECT TABLESPACE_NAME,TO_CHAR(SUM(NVL(BYTES,0))/1024/1024/1024, '99,999,990.99') AS FREE_BYTES FROM  USER_FREE_SPACE GROUP BY TABLESPACE_NAME) FREE
ON (USED.TABLESPACE_NAME = FREE.TABLESPACE_NAME);

As "there are tens of thousands of cells in the page" binding the click-event to every single cell will cause a terrible performance problem. There's a better way to do this, that is binding a click event to the body & then finding out if the cell element was the target of the click. Like this:

$('body').click(function(e){
       var Elem = e.target;
       if (Elem.nodeName=='td'){
           //.... your business goes here....
           // remember to replace $(this) with $(Elem)
       }
})

This method will not only do your task with native "td" tag but also with later appended "td". I think you'll be interested in this article about event binding & delegate

Or you can simply use the ".on()" method of jQuery with the same effect:

$('body').on('click', 'td', function(){
        ...
});

As far as I can tell there is no upper limit in 2008.

In SQL Server 2005 the code in your question fails on the assignment to the @GGMMsg variable with

Attempting to grow LOB beyond maximum allowed size of 2,147,483,647 bytes.

the code below fails with

REPLICATE: The length of the result exceeds the length limit (2GB) of the target large type.

However it appears these limitations have quietly been lifted. On 2008

DECLARE @y VARCHAR(MAX) = REPLICATE(CAST('X' AS VARCHAR(MAX)),92681); 

SET @y = REPLICATE(@y,92681);

SELECT LEN(@y) 

Returns

8589767761

I ran this on my 32 bit desktop machine so this 8GB string is way in excess of addressable memory

Running

select internal_objects_alloc_page_count
from sys.dm_db_task_space_usage
WHERE session_id = @@spid

Returned

internal_objects_alloc_page_co 
------------------------------ 
2144456    

so I presume this all just gets stored in LOB pages in tempdb with no validation on length. The page count growth was all associated with the SET @y = REPLICATE(@y,92681); statement. The initial variable assignment to @y and the LEN calculation did not increase this.

The reason for mentioning this is because the page count is hugely more than I was expecting. Assuming an 8KB page then this works out at 16.36 GB which is obviously more or less double what would seem to be necessary. I speculate that this is likely due to the inefficiency of the string concatenation operation needing to copy the entire huge string and append a chunk on to the end rather than being able to add to the end of the existing string. Unfortunately at the moment the .WRITE method isn't supported for varchar(max) variables.

Addition

I've also tested the behaviour with concatenating nvarchar(max) + nvarchar(max) and nvarchar(max) + varchar(max). Both of these allow the 2GB limit to be exceeded. Trying to then store the results of this in a table then fails however with the error message Attempting to grow LOB beyond maximum allowed size of 2147483647 bytes. again. The script for that is below (may take a long time to run).

DECLARE @y1 VARCHAR(MAX) = REPLICATE(CAST('X' AS VARCHAR(MAX)),2147483647); 
SET @y1 = @y1 + @y1;
SELECT LEN(@y1), DATALENGTH(@y1)  /*4294967294, 4294967292*/


DECLARE @y2 NVARCHAR(MAX) = REPLICATE(CAST('X' AS NVARCHAR(MAX)),1073741823); 
SET @y2 = @y2 + @y2;
SELECT LEN(@y2), DATALENGTH(@y2)  /*2147483646, 4294967292*/


DECLARE @y3 NVARCHAR(MAX) = @y2 + @y1
SELECT LEN(@y3), DATALENGTH(@y3)   /*6442450940, 12884901880*/

/*This attempt fails*/
SELECT @y1 y1, @y2 y2, @y3 y3

I found another way to solve it - use Table Lock. Sure, it can be unappropriate for your application - if you need to update table at same time.

See: Try using LOCK TABLES to lock the entire table, instead of the default action of InnoDB's MVCC row-level locking. If I'm not mistaken, the "lock table" is referring to the InnoDB internal structure storing row and version identifiers for the MVCC implementation with a bit identifying the row is being modified in a statement, and with a table of 60 million rows, probably exceeds the memory allocated to it. The LOCK TABLES command should alleviate this problem by setting a table-level lock instead of row-level:

SET @@AUTOCOMMIT=0;
LOCK TABLES avgvol WRITE, volume READ;
INSERT INTO avgvol(date,vol)
SELECT date,avg(vol) FROM volume
GROUP BY date;
UNLOCK TABLES;

You can increase the capacity of the stack by the following :

import sys
sys.setrecursionlimit(10000)

Like this?

public static void Test()
{
    using (var image = Image.FromFile(@"c:\logo.png"))
    using (var newImage = ScaleImage(image, 300, 400))
    {
        newImage.Save(@"c:\test.png", ImageFormat.Png);
    }
}

public static Image ScaleImage(Image image, int maxWidth, int maxHeight)
{
    var ratioX = (double)maxWidth / image.Width;
    var ratioY = (double)maxHeight / image.Height;
    var ratio = Math.Min(ratioX, ratioY);

    var newWidth = (int)(image.Width * ratio);
    var newHeight = (int)(image.Height * ratio);

    var newImage = new Bitmap(newWidth, newHeight);

    using (var graphics = Graphics.FromImage(newImage))
        graphics.DrawImage(image, 0, 0, newWidth, newHeight);

    return newImage;
}

There might be more than just one php.ini file. For example, when using WAMP there are 2 php.ini files in following directories:

• C:\wamp\bin\apache\apache2.4.9\bin
• C:\wamp\bin\php\php5.5.12

You need to edit the first one.

Try Uri.IsWellFormedUriString():

• The string is not correctly escaped.

    http://www.example.com/path???/file name
  

• The string is an absolute Uri that represents an implicit file Uri.

    c:\\directory\filename
  

• The string is an absolute URI that is missing a slash before the path.

    file://c:/directory/filename
  

• The string contains unescaped backslashes even if they are treated as forward slashes.

    http:\\host/path/file
  

• The string represents a hierarchical absolute Uri and does not contain "://".

    www.example.com/path/file
  

• The parser for the Uri.Scheme indicates that the original string was not well-formed.

    The example depends on the scheme of the URI.
  

I had been facing similar problem in downloading big files this works fine for me now:

safe_mode = off
max_input_time = 9000
memory_limit = 1073741824
post_max_size = 1073741824
file_uploads = On
upload_max_filesize = 1073741824
max_file_uploads = 100
allow_url_fopen = On

Hope this helps.

The problem with detecting stackoverflows is sometimes the stack trace will unwind and you won't be able to see what's actually going on.

I've found some of Chrome's newer debugging tools useful for this.

Hit the Performance tab, make sure Javascript samples are enabled and you'll get something like this.

It's pretty obvious where the overflow is here! If you click on extendObject you'll be able to actually see the exact line number in the code.

You can also see timings which may or may not be helpful or a red herring.

Another useful trick if you can't actually find the problem is to put lots of console.log statements where you think the problem is. The previous step above can help you with this.

In Chrome if you repeatedly output identical data it will display it like this showing where the problem is more clearly. In this instance the stack hit 7152 frames before it finally crashed:

You can increase the List View Threshold beyond the 5,000 default, but it is highly recommended that you don't, as it has performance implications. The recommended fix is to add an index to the field or fields used in the query (usually the ID field for a list or the Title field for a library).

When there is an index, that is used to retrieve the item(s); when there is no index the whole list is opened for a scan (and therefore hits the threshold). You create the index on the List (or Library) settings page.

This article is a good overview: http://office.microsoft.com/en-us/sharepoint-foundation-help/manage-lists-and-libraries-with-many-items-HA010377496.aspx

You can use:

show full processlist

which will list all the connections in MySQL and the current state of connection as well as the query being executed. There's also a shorter variant show processlist; which displays the truncated query as well as the connection stats.

setDatabasePath() method was deprecated in API level 19. I advise you to use storage locale like this:

webView.getSettings().setDomStorageEnabled(true);
webView.getSettings().setDatabaseEnabled(true);
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.KITKAT) {
    webView.getSettings().setDatabasePath("/data/data/" + webView.getContext().getPackageName() + "/databases/");
}

You're essentially running out of memory to run the process smoothly. Options that come to mind:

1. Specify more memory like you mentioned, try something in between like -Xmx512m first
2. Work with smaller batches of HashMap objects to process at once if possible
3. If you have a lot of duplicate strings, use String.intern() on them before putting them into the HashMap
4. Use the HashMap(int initialCapacity, float loadFactor) constructor to tune for your case

Can you update any other record within this table, or is this table heavily used? What I am thinking is that while it is attempting to acquire a lock that it needs to update this record the timeout that was set has timed out. You may be able to increase the time which may help.

You can try define in your LINQ expression only the field's that you will need.

Example. Imagine that you have an Model with Id, Name, Phone and Picture (byte array) and need to load from json into an select list.

LINQ Query:

var listItems = (from u in Users where u.name.Contains(term) select u).ToList();

The problem here is "select u" that get all fields. So, if you have big pictures, booomm.

How to solve? very, very simple.

var listItems = (from u in Users where u.name.Contains(term) select new {u.Id, u.Name}).ToList();

The best practices is select only the field that you will use.

Remember. This is a simple tip, but can help many ASP.NET MVC developpers.

Please also read comments to the accepted answer there, those contain valuable input.

I encountered a similar problem, and I used 2 flash drives as 'ReadyBoost'. The two drives gave additional 8GB boost of memory (for cache) and it solved the problem and also increased the speed of the system as a whole. To use Readyboost, right click on the drive, go to properties and select 'ReadyBoost' and select 'use this device' radio button and click apply or ok to configure.

To extend your max_execution_time you can use either ini_set or set_time_limit.

// Set maximum execution time to 10 seconds this way
ini_set('max_execution_time', 10);
// or this way
set_time_limit(10);

!! But be aware that, both functions restarts also counting of time script has already taken to execute

sleep(2);
ini_set('max_execution_time', 5);

register_shutdown_function(function(){
    var_dump(microtime(true) - $_SERVER['REQUEST_TIME_FLOAT']);
});

for(;;);

//
// var_dump outputs float(7.1981489658356)
//

so if you want to set exact maximum amount of time script can run, your command must be very first.

Differences between those two functions are

• set_time_limit does not return info whether it was successful but it will throw a warning on error.
• ini_set returns old value on success, or false on failure without any warning/error

If you are looking for the reason and don't want to fight the system settings, these are two major situations I faced:

1. You may have an infinite loop without next or recordest.movenext
2. Your text data is very large but you think it is not! The common reason for this situation is to copy-paste an Image from Microsoft word directly into the editor and so the server translates the image to data objects and saves it in your text field. This can easily occupies the database resources and causes buffer problem when you call the data again.

By setting android:maxEms to a given value together with android:layout_weight="1" will cause the TextView to wrap once it reaches the given length of the ems.

I fixed my pythonpath and everything was dandy when I imported stuff through the console, but all these previously unresolved imports were still marked as errors in my code, no matter how many times I restarted eclipse or refreshed/cleaned the project.

I right clicked the project->Pydev->Remove error markers and it got rid of that problem. Don't worry, if your code contains actual errors they will be re-marked.

It depends on many things. It's usually O(1), with a decent hash which itself is constant time... but you could have a hash which takes a long time to compute, and if there are multiple items in the hash map which return the same hash code, get will have to iterate over them calling equals on each of them to find a match.

In the worst case, a HashMap has an O(n) lookup due to walking through all entries in the same hash bucket (e.g. if they all have the same hash code). Fortunately, that worst case scenario doesn't come up very often in real life, in my experience. So no, O(1) certainly isn't guaranteed - but it's usually what you should assume when considering which algorithms and data structures to use.

In JDK 8, HashMap has been tweaked so that if keys can be compared for ordering, then any densely-populated bucket is implemented as a tree, so that even if there are lots of entries with the same hash code, the complexity is O(log n). That can cause issues if you have a key type where equality and ordering are different, of course.

And yes, if you don't have enough memory for the hash map, you'll be in trouble... but that's going to be true whatever data structure you use.

From Java SE 6 HotSpot[tm] Virtual Machine Garbage Collection Tuning

the following

Excessive GC Time and OutOfMemoryError

The concurrent collector will throw an OutOfMemoryError if too much time is being spent in garbage collection: if more than 98% of the total time is spent in garbage collection and less than 2% of the heap is recovered, an OutOfMemoryError will be thrown. This feature is designed to prevent applications from running for an extended period of time while making little or no progress because the heap is too small. If necessary, this feature can be disabled by adding the option -XX:-UseGCOverheadLimit to the command line.

The policy is the same as that in the parallel collector, except that time spent performing concurrent collections is not counted toward the 98% time limit. In other words, only collections performed while the application is stopped count toward excessive GC time. Such collections are typically due to a concurrent mode failure or an explicit collection request (e.g., a call to System.gc()).

in conjunction with a passage further down

One of the most commonly encountered uses of explicit garbage collection occurs with RMIs distributed garbage collection (DGC). Applications using RMI refer to objects in other virtual machines. Garbage cannot be collected in these distributed applications without occasionally collection the local heap, so RMI forces full collections periodically. The frequency of these collections can be controlled with properties. For example,

java -Dsun.rmi.dgc.client.gcInterval=3600000

-Dsun.rmi.dgc.server.gcInterval=3600000 specifies explicit collection once per hour instead of the default rate of once per minute. However, this may also cause some objects to take much longer to be reclaimed. These properties can be set as high as Long.MAX_VALUE to make the time between explicit collections effectively infinite, if there is no desire for an upper bound on the timeliness of DGC activity.

Seems to imply that the evaluation period for determining the 98% is one minute long, but it might be configurable on Sun's JVM with the correct define.

Of course, other interpretations are possible.

$num_words = 101;
$words = array();
$words = explode(" ", $original_string, $num_words);
$shown_string = "";

if(count($words) == 101){
   $words[100] = " ... ";
}

$shown_string = implode(" ", $words);

The character is a backslash \

From the bash manual:

The backslash character ‘\’ may be used to remove any special meaning for the next character read and for line continuation.

I was dealing with same error and after spending time solved it by adding below lines in web.config file

<system.web>
   <httpRuntime targetFramework="4.7.1" maxRequestLength="1048576"/>
</system.web>

and

 <system.webServer>
   <security>
      <requestFiltering>
        <requestLimits maxAllowedContentLength="1073741824" />
      </requestFiltering>
    </security>
</system.webServer>

If you cannot edit php.ini (on your server for example) you can attempt to change the php.ini parameters from within your php code. Try:

ini_set('max_execution_time', 'NUMBER OF SECONDS TO ALLOW BEFORE TIMEOUT');

If that doesn't work, try also setting 'set_time_limit' in the same way, beyond that I'd say your only option is to contact your host. These settings cannot be modified while in safe mode.

If you use a CLR function, you can convert the float to a string that looks just like the float, without all the extra 0's at the end.

CLR Function

[Microsoft.SqlServer.Server.SqlFunction(DataAccess = DataAccessKind.Read)]
[return: SqlFacet(MaxSize = 50)]
public static SqlString float_to_str(double Value, int TruncAfter)
{
  string rtn1 = Value.ToString("R");
  string rtn2 = Value.ToString("0." + new string('0', TruncAfter));

  if (rtn1.Length < rtn2.Length) { return rtn1; } else { return rtn2; }
}

.

Example

create table #temp (value float)
insert into #temp values (0.73), (0), (0.63921), (-0.70945), (0.28), (0.72000002861023), (3.7), (-0.01), (0.86), (0.55489), (0.439999997615814)

select value,
       dbo.float_to_str(value, 18) as converted,
       case when value = cast(dbo.float_to_str(value, 18) as float) then 1 else 0 end as same
from   #temp

drop table #temp

.

Output

value                  converted                  same

0.439999997615814      0.439999997615814          1

.

Caveat

All converted strings are truncated at 18 decimal places, and there are no trailing zeros. 18 digits of precision is not a problem for us. And, 100% of our FP numbers (close to 100,000 values) look identical as string values as they do in the database as FP numbers.

I use the following vba code where filename is a string containing the filename I want, and Function RemoveSpecialCharactersAndTruncate is defined below:

worksheet1.Name = RemoveSpecialCharactersAndTruncate(filename)

'Function to remove special characters from file before saving

Private Function RemoveSpecialCharactersAndTruncate$(ByVal FormattedString$)
    Dim IllegalCharacterSet$
    Dim i As Integer
'Set of illegal characters
    IllegalCharacterSet$ = "*." & Chr(34) & "//\[]:;|=,"
    'Iterate through illegal characters and replace any instances
    For i = 1 To Len(IllegalCharacterSet) - 1
        FormattedString$ = Replace(FormattedString$, Mid(IllegalCharacterSet, i, 1), "")
    Next
    'Return the value capped at 31 characters (Excel limit)
    RemoveSpecialCharactersAndTruncate$ = Left(FormattedString$, _
                           Application.WorksheetFunction.Min(Len(FormattedString), 31))
End Function

You could use some CSS and with the idea of kbrimington it should do the trick.

The CSS could be like this.

img {
  width:  75px;
  height: auto;
}

I got it from here: another post

If you use the InnoDB storage engine for (some of) your MySQL tables, you’ve probably already came across a problem with its default configuration. As you may have noticed in your MySQL’s data directory (in Debian/Ubuntu – /var/lib/mysql) lies a file called ‘ibdata1'. It holds almost all the InnoDB data (it’s not a transaction log) of the MySQL instance and could get quite big. By default this file has a initial size of 10Mb and it automatically extends. Unfortunately, by design InnoDB data files cannot be shrinked. That’s why DELETEs, TRUNCATEs, DROPs, etc. will not reclaim the space used by the file.

I think you can find good explanation and solution there :

JavaScript version in case if jQuery is not an option.

window.screen.availHeight

If you absolutely want to do one step resize you could probably load entire bitmap if android:largeHeap = true but as you can see this is not really advisable.

From docs: android:largeHeap Whether your application's processes should be created with a large Dalvik heap. This applies to all processes created for the application. It only applies to the first application loaded into a process; if you're using a shared user ID to allow multiple applications to use a process, they all must use this option consistently or they will have unpredictable results. Most apps should not need this and should instead focus on reducing their overall memory usage for improved performance. Enabling this also does not guarantee a fixed increase in available memory, because some devices are constrained by their total available memory.

If you often need to change the recursion limit (e.g. while solving programming puzzles) you can define a simple context manager like this:

import sys

class recursionlimit:
    def __init__(self, limit):
        self.limit = limit
        self.old_limit = sys.getrecursionlimit()

    def __enter__(self):
        sys.setrecursionlimit(self.limit)

    def __exit__(self, type, value, tb):
        sys.setrecursionlimit(self.old_limit)

Then to call a function with a custom limit you can do:

with recursionlimit(1500):
    print(fib(1000, 0))

On exit from the body of the with statement the recursion limit will be restored to the default value.

A similar variant with C# 6's Null propagation operator

public static string Truncate(this string value, int maxLength)
{
    return value?.Length <= maxLength ? value : value?.Substring(0, maxLength);
}

Please note, we are essentially checking if value is null twice here.

I ran into the same problem with an "update"-statement. My solution was simply to run through the operations available in phpMyAdmin for the table. I optimized, flushed and defragmented the table (not in that order). No need to drop the table and restore it from backup for me. :)

If you mean that you want to enable the submit after the user has typed at least one character, then you need to attach a key event that will check it for you.

Something like:

$("#fbss").keypress(function() {
    if($(this).val().length > 1) {
         // Enable submit button
    } else {
         // Disable submit button
    }
});

The limit is dependent on both the server and the client used (and if applicable, also the proxy the server or the client is using).

Most web servers have a limit of 8192 bytes (8 KB), which is usually configurable somewhere in the server configuration. As to the client side matter, the HTTP 1.1 specification even warns about this. Here's an extract of chapter 3.2.1:

Note: Servers ought to be cautious about depending on URI lengths above 255 bytes, because some older client or proxy implementations might not properly support these lengths.

The limit in Internet Explorer and Safari is about 2 KB, in Opera about 4 KB and in Firefox about 8 KB. We may thus assume that 8 KB is the maximum possible length and that 2 KB is a more affordable length to rely on at the server side and that 255 bytes is the safest length to assume that the entire URL will come in.

If the limit is exceeded in either the browser or the server, most will just truncate the characters outside the limit without any warning. Some servers however may send an HTTP 414 error.

If you need to send large data, then better use POST instead of GET. Its limit is much higher, but more dependent on the server used than the client. Usually up to around 2 GB is allowed by the average web server.

This is also configurable somewhere in the server settings. The average server will display a server-specific error/exception when the POST limit is exceeded, usually as an HTTP 500 error.

In my case I accidentally used SSL in the Virtualhost configuration for port 80, instead of 443.

Basically, you get connections in the Sleep state when :

• a PHP script connects to MySQL
• some queries are executed
• then, the PHP script does some stuff that takes time
  • without disconnecting from the DB
• and, finally, the PHP script ends
  • which means it disconnects from the MySQL server

So, you generally end up with many processes in a Sleep state when you have a lot of PHP processes that stay connected, without actually doing anything on the database-side.

A basic idea, so : make sure you don't have PHP processes that run for too long -- or force them to disconnect as soon as they don't need to access the database anymore.

Another thing, that I often see when there is some load on the server :

• There are more and more requests coming to Apache
  • which means many pages to generate
• Each PHP script, in order to generate a page, connects to the DB and does some queries
• These queries take more and more time, as the load on the DB server increases
• Which means more processes keep stacking up

A solution that can help is to reduce the time your queries take -- optimizing the longest ones.

There's no magical solution of displaying something outside an overflow hidden container.

A similar effect can be achieved by having an absolute positioned div that matches the size of its parent by positioning it inside your current relative container (the div you don't wish to clip should be outside this div):

#1 .mask {
  width: 100%;
  height: 100%;
  position: absolute;
  z-index: 1;
  overflow: hidden;
}

Take in mind that if you only have to clip content on the x axis (which appears to be your case, as you only have set the div's width), you can use overflow-x: hidden.

I resolved this issue by creating a file called .user.ini in the directory where the PHP file scripts reside (this means any PHP script in this directory gets the new file size limit)

The contents of .user.ini were:

upload_max_filesize = 40M
post_max_size = 40M

Well I've tried everything I found on the internet and none of them worked. Calling System.gc() only drags down the speed of app. Recycling bitmaps in onDestroy didn't work for me too.

The only thing that works now is to have a static list of all the bitmap so that the bitmaps survive after a restart. And just use the saved bitmaps instead of creating new ones every time the activity if restarted.

In my case the code looks like this:

private static BitmapDrawable currentBGDrawable;

if (new File(uriString).exists()) {
    if (!uriString.equals(currentBGUri)) {
        freeBackground();
        bg = BitmapFactory.decodeFile(uriString);

        currentBGUri = uriString;
        bgDrawable = new BitmapDrawable(bg);
        currentBGDrawable = bgDrawable;
    } else {
        bgDrawable = currentBGDrawable;
    }
}

Strings are immutable, so using

public string GenerateString()
{
    return
        "abc" +
        "def";
}

will slow you performance - each of those values is a string literal which must be concatenated at runtime - bad news if you reuse the method/property/whatever alot...

Store your string literals in resources is a good idea...

public string GenerateString()
{
    return Resources.MyString;
}

That way it is localisable and the code is tidy (although performance is pretty terrible).

Thanks to this guys I did it http://highoncoding.com/Articles/848_Creating_iPad_Dashboard_Using_UIViewController_Containment.aspx

This message means that for some reason the garbage collector is taking an excessive amount of time (by default 98% of all CPU time of the process) and recovers very little memory in each run (by default 2% of the heap).

This effectively means that your program stops doing any progress and is busy running only the garbage collection at all time.

To prevent your application from soaking up CPU time without getting anything done, the JVM throws this Error so that you have a chance of diagnosing the problem.

The rare cases where I've seen this happen is where some code was creating tons of temporary objects and tons of weakly-referenced objects in an already very memory-constrained environment.

Check out the Java GC tuning guide, which is available for various Java versions and contains sections about this specific problem:

• Java 11 tuning guide has dedicated sections on excessive GC for different garbage collectors:
  • for the Parallel Collector
  • for the Concurrent Mark Sweep (CMS) Collector
  • there is no mention of this specific error condition for the Garbage First (G1) collector.
• Java 8 tuning guide and its Excessive GC section
• Java 6 tuning guide and its Excessive GC section.

InnerHTML should be innerHTML:

document.getElementById('LblAboutMeCount').innerHTML = charsleft;

You should bind your checkLength function to your textarea with jQuery rather than calling it inline and rather intrusively:

$(document).ready(function() {
    $('textarea[name=text]').keypress(function(e) {
        checkLength($(this),512,$('#LblTextCount'));
    }).focus(function() {
        checkLength($(this),512,$('#LblTextCount'));
    });
});

You can neaten up checkLength by using more jQuery, and I wouldn't use 'object' as a formal parameter:

function checkLength(obj, maxlength, label) {
    charsleft = (maxlength - obj.val().length);
    // never allow to exceed the specified limit
    if( charsleft < 0 ) {
        obj.val(obj.val().substring(0, maxlength-1));
    }
    // I'm trying to set the value of charsleft into the label
    label.text(charsleft);
    $('#LblAboutMeCount').html(charsleft);
}

So if you apply the above, you can change your markup to:

<textarea name="text"></textarea>

Well for Wamp User,

Go to: wamp\apps\phpmyadmin3.3.9\libraries

Under line 536, locate $cfg['ExecTimeLimit'] = 0;

and change the value from 0 to 6000. e.g

$cfg['ExecTimeLimit'] = 0;

To

$cfg['ExecTimeLimit'] = 6000;

Restart wamp server and phew.

It works like magic !

Dont know if someone else has this problem but wrapping my TextBlock into a ScrollViewer somewhow messed up my UI - as a simple workaround I figured out that replacing the TextBlock by a TextBox like this one

<TextBox  Name="textBlock" SelectionBrush="Transparent" Cursor="Arrow" IsReadOnly="True" Text="My Text" VerticalScrollBarVisibility="Auto">

creates a TextBox that looks and behaves like a TextBlock with a scrollbar (and you can do it all in the designer).

You do not need to do with web.config You can use short property during catch value of the passing list For example declare a model like

public class BookModel
    {
        public decimal id { get; set; }  // 1 

        public string BN { get; set; } // 2 Book Name

        public string BC { get; set; } // 3 Bar Code Number

        public string BE { get; set; } // 4 Edition Name

        public string BAL { get; set; } // 5 Academic Level

        public string BCAT { get; set; } // 6 Category
}

here i use short proporties like BC =barcode BE=book edition and so on

xampp in ubuntu

cd /opt/lampp/etc
vim php.ini

Find:
  post_max_size = 8M
  upload_max_filesize = 2M
  max_execution_time = 30
  max_input_time = 60
  memory_limit = 8M

Change to:
  post_max_size = 750M
  upload_max_filesize = 750M
  max_execution_time = 5000
  max_input_time = 5000
  memory_limit = 1000M

sudo /opt/lampp/lampp restart

Try this:

div {
    width: 200px;
    word-wrap: break-word;
}

Using multiple comment/answers in this thread, here is my solution :

import hashlib
def md5_for_file(path, block_size=256*128, hr=False):
    '''
    Block size directly depends on the block size of your filesystem
    to avoid performances issues
    Here I have blocks of 4096 octets (Default NTFS)
    '''
    md5 = hashlib.md5()
    with open(path,'rb') as f: 
        for chunk in iter(lambda: f.read(block_size), b''): 
             md5.update(chunk)
    if hr:
        return md5.hexdigest()
    return md5.digest()

• This is "pythonic"
• This is a function
• It avoids implicit values: always prefer explicit ones.
• It allows (very important) performances optimizations

And finally,

- This has been built by a community, thanks all for your advices/ideas.

Make sure the outermost div has the following CSS properties:

The real answer, in 2016 and 2017, is: Use Ola Hallengren's scripts:

That is all any of us need to know or bother with, at this point in our mutual evolution.

I'm having a very similar problem. In the past, this has been related to serialization problems. If you are still having this problem, can you verify that you can correctly serialize the objects you are returning. Specifically, if you are using Linq-To-Sql objects that have relationships, there are known serialization problems if you put a back reference on a child object to the parent object and mark that back reference as a DataMember.

You can verify serialization by writing a console app that serializes and deserializes your objects using the DataContractSerializer on the server side and whatever serialization methods your client uses. For example, in our current application, we have both WPF and Compact Framework clients. I wrote a console app to verify that I can serialize using a DataContractSerializer and deserialize using an XmlDesserializer. You might try that.

Also, if you are returning Linq-To-Sql objects that have child collections, you might try to ensure that you have eagerly loaded them on the server side. Sometimes, because of lazy loading, the objects being returned are not populated and may cause the behavior you are seeing where the request is sent to the service method multiple times.

If you have solved this problem, I'd love to hear how because I'm stuck with it too. I have verified that my issue is not serialization so I'm at a loss.

UPDATE: I'm not sure if it will help you any but the Service Trace Viewer Tool just solved my problem after 5 days of very similar experience to yours. By setting up tracing and then looking at the raw XML, I found the exceptions that were causing my serialization problems. It was related to Linq-to-SQL objects that occasionally had more child objects than could be successfully serialized. Adding the following to your web.config file should enable tracing:

<sharedListeners>
    <add name="sharedListener"
         type="System.Diagnostics.XmlWriterTraceListener"
         initializeData="c:\Temp\servicetrace.svclog" />
  </sharedListeners>
  <sources>
    <source name="System.ServiceModel" switchValue="Verbose, ActivityTracing" >
      <listeners>
        <add name="sharedListener" />
      </listeners>
    </source>
    <source name="System.ServiceModel.MessageLogging" switchValue="Verbose">
      <listeners>
        <add name="sharedListener" />
      </listeners>
    </source>
  </sources>

The resulting file can be opened with the Service Trace Viewer Tool or just in IE to examine the results.

As others have pointed, having a response entity in an error code is perfectly allowable.

Do remember that 5xx errors are server-side, aka the client cannot change anything to its request to make the request pass. If the client's quota is exceeded, that's definitly not a server error, so 5xx should be avoided.

Using CSS you can do it if you add the following style to a tag, but you will need a wav file:

<style type="text/css">
        .beep {cue: url("beep.wav") }
</style>

var body=document.getElementByTagName("body");
body.className=body.className + " " + "beep";

If you have cygwin installed, from it's bash shell, run your executable, say MyProgram, using the time utility, like so:

/usr/bin/time ./MyProgram

This will report how long the execution of your program took -- the output would look something like the following:

real    0m0.792s
user    0m0.046s
sys     0m0.218s

You could also manually modify your C program to instrument it using the clock() library function, like so:

#include <time.h>
int main(void) {
    clock_t tStart = clock();
    /* Do your stuff here */
    printf("Time taken: %.2fs\n", (double)(clock() - tStart)/CLOCKS_PER_SEC);
    return 0;
}

If you want to wrap your text but maintain alignment then you can wrap that cell in a minipage or varwidth environment (varwidth comes from the varwidth package). Varwidth will be "as wide as it's contents but no wider than X". You can create a custom column type which acts like "p{xx}" but shrinks to fit by using

\newcolumntype{M}[1]{>{\begin{varwidth}[t]{#1}}l<{\end{varwidth}}}

which may require the array package. Then when you use something like \begin{tabular}{llM{2in}} the first two columns we be normal left-aligned and the third column will be normal left aligned but if it gets wider than 2in then the text will be wrapped.

Hi solution mentioned by Damien McGivern, Works on IIS6 only,

It does not work on IIS7 and ASP.NET Development Server. I get page displaying "404 - File or directory not found."

Any ideas?

EDIT:

Got it... This solution still doesn't work on ASP.NET Development Server, but I got the reason why it was not working on IIS7 in my case.

The reason is IIS7 has a built-in request scanning which imposes an upload file cap which defaults to 30000000 bytes (which is slightly less that 30MB).

And I was trying to upload file of size 100 MB to test the solution mentioned by Damien McGivern (with maxRequestLength="10240" i.e. 10MB in web.config). Now, If I upload the file of size > 10MB and < 30 MB then the page is redirected to the specified error page. But if the file size is > 30MB then it show the ugly built-in error page displaying "404 - File or directory not found."

So, to avoid this, you have to increase the max. allowed request content length for your website in IIS7. That can be done using following command,

appcmd set config "SiteName" -section:requestFiltering -requestLimits.maxAllowedContentLength:209715200 -commitpath:apphost

I have set the max. content length to 200MB.

After doing this setting, the page is succssfully redirected to my error page when I try to upload file of 100MB

Refer, http://weblogs.asp.net/jgalloway/archive/2008/01/08/large-file-uploads-in-asp-net.aspx for more details.

Add the following lines to your manifest.xml file:

<application

    android:hardwareAccelerated="false"
    android:largeHeap="true">

    <activity>
    </activity>

</application>

I recently did this. I was trying to make a compact version of my database for testing on the road, but I just couldn't get it to shrink, no matter how many rows I deleted. Eventually, after many other commands in this thread, I found that my clustered indexes were not getting rebuilt after deleting rows. Rebuilding my indexes made it so I could shrink properly.

Put the values in a temporary table and then do a select where id in (select id from temptable)

Python language reference:

In order to avoid infinite recursion in this method, its implementation should always call the base class method with the same name to access any attributes it needs, for example, object.__getattribute__(self, name).

Meaning:

def __getattribute__(self,name):
    ...
        return self.__dict__[name]

You're calling for an attribute called __dict__. Because it's an attribute, __getattribute__ gets called in search for __dict__ which calls __getattribute__ which calls ... yada yada yada

return  object.__getattribute__(self, name)

Using the base classes __getattribute__ helps finding the real attribute.

Whenever I talk managed vs. unmanaged performance, I like to point to the series Rico (and Raymond) did comparing C++ and C# versions of a Chinese/English dictionary. This google search will let you read for yourself, but I like Rico's summary.

So am I ashamed by my crushing defeat? Hardly. The managed code got a very good result for hardly any effort. To defeat the managed Raymond had to:

• Write his own file I/O stuff
• Write his own string class
• Write his own allocator
• Write his own international mapping

Of course he used available lower level libraries to do this, but that's still a lot of work. Can you call what's left an STL program? I don't think so, I think he kept the std::vector class which ultimately was never a problem and he kept the find function. Pretty much everything else is gone.

So, yup, you can definately beat the CLR. Raymond can make his program go even faster I think.

Interestingly, the time to parse the file as reported by both programs internal timers is about the same -- 30ms for each. The difference is in the overhead.

For me the bottom line is that it took 6 revisions for the unmanaged version to beat the managed version that was a simple port of the original unmanaged code. If you need every last bit of performance (and have the time and expertise to get it), you'll have to go unmanaged, but for me, I'll take the order of magnitude advantage I have on the first versions over the 33% I gain if I try 6 times.

Why not just use type casting?

(char*) "test"

plt.gca().axes.yaxis.set_ticklabels([])

In addition to @Ceki 's answer, If you are using logback and setup a config file in your project (usually logback.xml), you can define the log to plot the stack trace as well using

<encoder>
    <pattern>%date |%-5level| [%thread] [%file:%line] - %msg%n%ex{full}</pattern> 
</encoder>

the %ex in pattern is what makes the difference

If you do not mind using an external library, Thumbnailator can perform scaling of BufferedImages.

Thumbnailator will take care of handling the Java 2D processing (such as using Graphics2D and setting appropriate rendering hints) so that a simple fluent API call can be used to resize images:

BufferedImage image = Thumbnails.of(originalImage).scale(2.0).asBufferedImage();

Although Thumbnailator, as its name implies, is geared toward shrinking images, it will do a decent job enlarging images as well, using bilinear interpolation in its default resizer implementation.

Disclaimer: I am the maintainer of the Thumbnailator library.

Hashing algorithms are usually cryptographic in nature, but the principal difference is that encryption is reversible through decryption, and hashing is not.

An encryption function typically takes input and produces encrypted output that is the same, or slightly larger size.

A hashing function takes input and produces a typically smaller output, typically of a fixed size as well.

While it isn't possible to take a hashed result and "dehash" it to get back the original input, you can typically brute-force your way to something that produces the same hash.

In other words, if a authentication scheme takes a password, hashes it, and compares it to a hashed version of the requires password, it might not be required that you actually know the original password, only its hash, and you can brute-force your way to something that will match, even if it's a different password.

Hashing functions are typically created to minimize the chance of collisions and make it hard to just calculate something that will produce the same hash as something else.

From the docs

• can I use the above method without any negative impact and without compromising a future appstore submission?

Bitcode will allow apple to optimise the app without you having to submit another build. But, you can only enable this feature if all frameworks and apps in the app bundle have this feature enabled. Having it helps, but not having it should not have any negative impact.

• What does the ENABLE_BITCODE actually do, will it be a non-optional requirement in the future?

For iOS apps, bitcode is the default, but optional. If you provide bitcode, all apps and frameworks in the app bundle need to include bitcode. For watchOS apps, bitcode is required.

• Are there any performance impacts if I enable / disable it?

The App Store and operating system optimize the installation of iOS and watchOS apps by tailoring app delivery to the capabilities of the user’s particular device, with minimal footprint. This optimization, called app thinning, lets you create apps that use the most device features, occupy minimum disk space, and accommodate future updates that can be applied by Apple. Faster downloads and more space for other apps and content provides a better user experience.

There should not be any performance impacts.

preg_replace('/[^0-9]/', '', $string);

This should do better job!...

QUICK ANSWER (very simplified!)

json.load() takes a FILE

json.load() expects a file (file object) - e.g. a file you opened before given by filepath like 'files/example.json'.

json.loads() takes a STRING

json.loads() expects a (valid) JSON string - i.e. {"foo": "bar"}

EXAMPLES

Assuming you have a file example.json with this content: { "key_1": 1, "key_2": "foo", "Key_3": null }

>>> import json
>>> file = open("example.json")

>>> type(file)
<class '_io.TextIOWrapper'>

>>> file
<_io.TextIOWrapper name='example.json' mode='r' encoding='UTF-8'>

>>> json.load(file)
{'key_1': 1, 'key_2': 'foo', 'Key_3': None}

>>> json.loads(file)
Traceback (most recent call last):
  File "/usr/local/python/Versions/3.7/lib/python3.7/json/__init__.py", line 341, in loads
TypeError: the JSON object must be str, bytes or bytearray, not TextIOWrapper


>>> string = '{"foo": "bar"}'

>>> type(string)
<class 'str'>

>>> string
'{"foo": "bar"}'

>>> json.loads(string)
{'foo': 'bar'}

>>> json.load(string)
Traceback (most recent call last):
  File "/usr/local/python/Versions/3.7/lib/python3.7/json/__init__.py", line 293, in load
    return loads(fp.read(),
AttributeError: 'str' object has no attribute 'read'

The problem is that you are asking for an object of type ChannelSearchEnum but what you actually have is an object of type List<ChannelSearchEnum>.

You can achieve this with:

Type collectionType = new TypeToken<List<ChannelSearchEnum>>(){}.getType();
List<ChannelSearchEnum> lcs = (List<ChannelSearchEnum>) new Gson()
               .fromJson( jstring , collectionType);

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

APP_STL := gnustl_static

to

APP_STL := c++_static

For those not getting a solution for older answers, i simply put my file name as the very first line in my code.

like so

 #ruby_file_name_here.rb

 puts "hello world"

Python has importing and namespacing, which are good. In Python you can import into the current namespace, like:

>>> from test import disp
>>> disp('World!')

Or with a namespace:

>>> import test
>>> test.disp('World!')

try like this

var username= "<%= Session["UserName"]%>";

I found another server side solution for web dev using PHP to get the size of an iframe.

First is using server script PHP to an external call via internal function: (like a file_get_contents with but curl and dom).

function curl_get_file_contents($url,$proxyActivation=false) {
    global $proxy;
    $c = curl_init();
    curl_setopt($c, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($c, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.2; en-US; rv:1.8.1.7) Gecko/20070914 Firefox/2.0.0.7");
    curl_setopt($c, CURLOPT_REFERER, $url);
    curl_setopt($c, CURLOPT_URL, $url);
    curl_setopt($c, CURLOPT_FOLLOWLOCATION, 1);
    if($proxyActivation) {
        curl_setopt($c, CURLOPT_PROXY, $proxy);
    }
    $contents = curl_exec($c);
    curl_close($c);
    $dom = new DOMDocument();
    $dom->preserveWhiteSpace = false;
    @$dom->loadHTML($contents);
    $form = $dom->getElementsByTagName("body")->item(0);
    if ($contents) //si on a du contenu
        return $dom->saveHTML();
    else
        return FALSE;
}
$url = "http://www.google.com"; //Exernal url test to iframe
<html>
    <head>
    <script type="text/javascript">

    </script>
    <style type="text/css">
    #iframe_reserve {
        width: 560px;
        height: 228px
    }
    </style>
    </head>

    <body>
        <div id="iframe_reserve"><?php echo curl_get_file_contents($url); ?></div>

        <iframe id="myiframe" src="http://www.google.com" scrolling="no" marginwidth="0" marginheight="0" frameborder="0"  style="overflow:none; width:100%; display:none"></iframe>

        <script type="text/javascript">
            window.onload = function(){
            document.getElementById("iframe_reserve").style.display = "block";
            var divHeight = document.getElementById("iframe_reserve").clientHeight;
            document.getElementById("iframe_reserve").style.display = "none";
            document.getElementById("myiframe").style.display = "block";
            document.getElementById("myiframe").style.height = divHeight;
            alert(divHeight);
            };
        </script>
    </body>
</html>

You need to display under the div (iframe_reserve) the html generated by the function call by using a simple echo curl_get_file_contents("location url iframe","activation proxy")

After doing this a body event function onload with javascript take height of the page iframe just with a simple control of the content div (iframe_reserve)

So I used divHeight = document.getElementById("iframe_reserve").clientHeight; to get height of the page external we are going to call after masked the div container (iframe_reserve). After this we load the iframe with its good height that's all.

You can use the datetime module for working with dates and times in Python. The strftime method allows you to produce string representation of dates and times with a format you specify.

>>> import datetime
>>> datetime.date.today().strftime("%B %d, %Y")
'July 23, 2010'
>>> datetime.datetime.now().strftime("%I:%M%p on %B %d, %Y")
'10:36AM on July 23, 2010'

I have used "Pattern 2 - the "factory helper pattern"

Pattern 2 - the factory helper pattern

One case where this pattern won't work is if MyClass is final. Most of the Mockito framework doesn't play particularly well with final classes; and this includes the use of spy(). Another case is where MyClass uses getClass() somewhere, and requires the resulting value to be MyClass. This won't work, because the class of a spy is actually a Mockito-generated subclass of the original class.

In either of these cases, you'll need the slightly more robust factory helper pattern, as follows.

public class MyClass{
  static class FactoryHelper{
      Foo makeFoo( A a, B b, C c ){
          return new Foo( a, b, c );
      }
  }

  //...

  private FactoryHelper helper;
  public MyClass( X x, Y y ){
      this( x, y, new FactoryHelper());
  } 

  MyClass( X x, Y, y, FactoryHelper helper ){

      //...

      this.helper = helper;
  } 

  //...

  Foo foo = helper.makeFoo( a, b, c );
}

So, you have a special constructor, just for testing, that has an additional argument. This is used from your test class, when creating the object that you're going to test. In your test class, you mock the FactoryHelper class, as well as the object that you want to create.

@Mock private MyClass.FactoryHelper mockFactoryHelper;
@Mock private Foo mockFoo;
private MyClass toTest;

and you can use it like this

toTest = new MyClass( x, y, mockFactoryHelper ); 
when( mockFactoryHelper.makeFoo( 
  any( A.class ), any( B.class ), any( C.class )))
  .thenReturn( mockFoo );

Actually, what I figured out while hosting my web app is the the code you developed on your local Machine is of higher version than the hosting company offers you. If you have admin privileges you may be able to change the Microsoft ASP.NET version support under web hosting setting

If you can stand to use sed (possibly execute from within your program, it'd be as simple as:

sed 's/(.*)//g'

To get the filenames, use:

var files = document.getElementById('inputElementID').files;

Using jQuery (since you already are) you can adapt this to the following:

$('input[type="file"][multiple]').change(
    function(e){
        var files = this.files;
        for (i=0;i<files.length;i++){
            console.log(files[i].fileName + ' (' + files[i].fileSize + ').');
        }
        return false;
    });

If it has to be really fast you can include a list of primes:
http://www.bigprimes.net/archive/prime/

If you just have to know if a certain number is a prime number, there are various prime tests listed on wikipedia. They are probably the fastest method to determine if large numbers are primes, especially because they can tell you if a number is not a prime.

Note: I have verified this in the latest version of IE, and other browsers like Mozilla and Chrome and this works for me. Hope it works for others as well.

if (data == "" || data == undefined) {
    alert("Falied to open PDF.");
} else { //For IE using atob convert base64 encoded data to byte array
    if (window.navigator && window.navigator.msSaveOrOpenBlob) {
        var byteCharacters = atob(data);
        var byteNumbers = new Array(byteCharacters.length);
        for (var i = 0; i < byteCharacters.length; i++) {
            byteNumbers[i] = byteCharacters.charCodeAt(i);
        }
        var byteArray = new Uint8Array(byteNumbers);
        var blob = new Blob([byteArray], {
            type: 'application/pdf'
        });
        window.navigator.msSaveOrOpenBlob(blob, fileName);
    } else { // Directly use base 64 encoded data for rest browsers (not IE)
        var base64EncodedPDF = data;
        var dataURI = "data:application/pdf;base64," + base64EncodedPDF;
        window.open(dataURI, '_blank');
    }

}

Did you maybe use some <tab> instead of spaces?

Try remove all the spaces before the code and readd them using <space> characters, just to be sure it's not a <tab>.

If you don't want to install the cors library and instead want to fix your original code, the other step you are missing is that Access-Control-Allow-Origin:* is wrong. When passing Authentication tokens (e.g. JWT) then you must explicitly state every url that is calling your server. You can't use "*" when doing authentication tokens.

I just found a solution for jaxrs-ri-2.16 - simply use

String output = response.readEntity(String.class)

this delivers the content as expected.

May be with:

SELECT count(*) FROM `table` 
where 
    created_at>='2011-03-17 06:42:10' and created_at<='2011-03-17 07:42:50';

or use between:

SELECT count(*) FROM `table` 
where 
    created_at between '2011-03-17 06:42:10' and '2011-03-17 07:42:50';

You can change the datetime as per your need. May be use curdate() or now() to get the desired dates.

This might not be relevant to your specific problem, but the error message you mentioned has many causes, one of them is using a return type for an [OperationContract] that is either abstract, interface, or not known to the WCF client code.

Check the post (and solution) below

You need to escape the . because it has the meaning of "an arbitrary character" in a regular expression.

mystring = mystring.replace(/\./g,' ')

I had the same problem.

To find out the exact source of it I switched on logging in web.config file:

<aspNetCore processPath="dotnet" arguments=".\MyWebService.dll" stdoutLogEnabled="**true**" stdoutLogFile=".\logs\stdout" />

and created logs subfolder in MyWebService root folder.

After restarting IIS and trying to execute API I got an error and it was missing of proper Core Runtime. After downloading an installing DotNetCore.1.0.5_1.1.2-WindowsHosting the error gone.

In Bash and zsh (and perhaps other shells), you can use process substitution (Bash/zsh) to create a file on the fly, and then use that as input to the next process in the pipeline chain.

For example, I was trying to parse JSON output from cURL using jq and less, but was getting the Failed writing body error.

# Note: this does NOT work
curl https://gitlab.com/api/v4/projects/ | jq | less

When I rewrote it using process substitution, it worked!

# this works!
jq "" <(curl https://gitlab.com/api/v4/projects/) | less

Note: jq uses its 2nd argument to specify an input file

Bonus: If you're using jq like me and want to keep the colorized output in less, use the following command line instead:

jq -C "" <(curl https://gitlab.com/api/v4/projects/) | less -r

(Thanks to Kowaru for their explanation of why Failed writing body was occurring. However, their solution of using tac twice didn't work for me. I also wanted to find a solution that would scale better for large files and tries to avoid the other issues noted as comments to that answer.)

I'm not sure what problem you are solving, but when I have two side by side containers that need to be the same height, I run a little javascript on page load that finds the maximum height of the two and explicitly sets the other to the same height. It seems to me that height: 100% might just mean "make it the size needed to fully contain the content" when what you really want is "make both the size of the largest content."

Note: you'll need to resize them again if anything happens on the page to change their height -- like a validation summary being made visible or a collapsible menu opening.

In Pyspark, to run local spark application using Pycharm use below lines

os.environ['HADOOP_HOME'] = "C:\\winutils"
print os.environ['HADOOP_HOME']

I needed to extract text between tags and aggregate (by concat) the text including in innner tags.

/node() did the job, while /text() made half job

/text() only returned text not included in inner tags, because inner tags are not "text nodes". You may think, "just extract text included in the inner tags in an additional xpath", however, it becomes challenging to sort the text in this original order because you dont know where to place the aggregated text from the inner tags!because you dont know where to place the aggregated text from the inner nodes.

2. no induction of NF-KB factor was detected

You'll have it all (with some plugins).

Btw, snippetsEmu is a nice tool for coding with useful snippets (like in TextMate). You can use (or modify) a pre-made package or make your own.

Typically, your help output should include:

• Description of what the app does
• Usage syntax, which:
  • Uses [options] to indicate where the options go
  • arg_name for a required, singular arg
  • [arg_name] for an optional, singular arg
  • arg_name... for a required arg of which there can be many (this is rare)
  • [arg_name...] for an arg for which any number can be supplied
  • note that arg_name should be a descriptive, short name, in lower, snake case
• A nicely-formatted list of options, each:
  • having a short description
  • showing the default value, if there is one
  • showing the possible values, if that applies
  • Note that if an option can accept a short form (e.g. -l) or a long form (e.g. --list), include them together on the same line, as their descriptions will be the same
• Brief indicator of the location of config files or environment variables that might be the source of command line arguments, e.g. GREP_OPTS
• If there is a man page, indicate as such, otherwise, a brief indicator of where more detailed help can be found

Note further that it's good form to accept both -h and --help to trigger this message and that you should show this message if the user messes up the command-line syntax, e.g. omits a required argument.

The manpage for types.h says:

size_t shall be an unsigned integer type

The chosen answer is great, but still I would like to add something small to the topic. An illustration.

It clearly demonstrates how the different phases binded to different plugins and the goals that those plugins expose.

So, let's examine a case of running something like mvn compile:

• It's a phase which execute the compiler plugin with compile goal
• Compiler plugin got different goals. For mvn compile it's mapped to a specific goal, the compile goal.
• It's the same as running mvn compiler:compile

Therefore, phase is made up of plugin goals.

In order to support Sql on DataFrames, first it requires a table definition with column names are required, along with if it creates tables the hive metastore will get lot unnecessary tables, because Spark-Sql natively resides on hive. So it will create a temporary view, which temporarily available in hive for time being and used as any other hive table, once the Spark Context stop it will be removed.

In order to create the view, developer need an utility called createOrReplaceTempView

For macOS Mojave , additional configuration was required, for compilers to find openssl you may need to set:

export LDFLAGS="-L/usr/local/opt/openssl/lib"
export CPPFLAGS="-I/usr/local/opt/openssl/include"

The proper way to do it is probably to break down the method by putting the try-catch block in a separate method, and use a return statement:

public void someMethod() {
    try {
        ...
        if (condition)
            return;
        ...
    } catch (SomeException e) {
        ...
    }
}

If the code involves lots of local variables, you may also consider using a break from a labeled block, as suggested by Stephen C:

label: try {
    ...
    if (condition)
        break label;
    ...
} catch (SomeException e) {
    ...
}

You want the Dictionary class.

All the solutions suggest you to use the predefined float value through code.

But in case you are wondering how to reference the predefined float value in XML (for example layouts), then following is an example of what I did and it's working perfectly:

Define resource values as type="integer" but format="float", for example:

<item name="windowWeightSum" type="integer" format="float">6.0</item>
<item name="windowNavPaneSum" type="integer" format="float">1.5</item>
<item name="windowContentPaneSum" type="integer" format="float">4.5</item>

And later use them in your layout using @integer/name_of_resource, for example:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:weightSum="@integer/windowWeightSum"                 // float 6.0
    android:orientation="horizontal">

    <LinearLayout
        android:layout_width="0dp"
        android:layout_height="match_parent"
        android:layout_weight="@integer/windowNavPaneSum"        // float 1.5
        android:orientation="vertical">
        <!-- other views -->
    </LinearLayout>

    <LinearLayout
        android:layout_width="0dp"
        android:layout_height="match_parent"
        android:layout_weight="@integer/windowContentPaneSum"    // float 4.5
        android:orientation="vertical">
        <!-- other views -->
    </LinearLayout>

</LinearLayout>

You can use a dictionary too.

def install():
    print "In install"

methods = {'install': install}

method_name = 'install' # set by the command line options

    methods[method_name]() # + argument list of course
else:
    raise Exception("Method %s not implemented" % method_name)

• If solution contains more than one project, try building them one at a time.
• Try restart Visual Studio.
• Try restart Computer.
• Try "Rebuild all"
• Try "Clean Solution" then remove your "vspscc" files and "vssscc" files and then restart Visual Studio and then "Rebuild All".

This did the trick for me:

docker run -dit ubuntu

After it, I checked for the processes running using:

docker ps -a

For attaching again the container

docker attach CONTAINER_NAME

TIP: For exiting without stopping the container type: ^P^Q

The header just denotes what the content is encoded in. It is not necessarily possible to deduce the type of the content from the content itself, i.e. you can't necessarily just look at the content and know what to do with it. That's what HTTP headers are for, they tell the recipient what kind of content they're (supposedly) dealing with.

Content-type: application/json; charset=utf-8 designates the content to be in JSON format, encoded in the UTF-8 character encoding. Designating the encoding is somewhat redundant for JSON, since the default (only?) encoding for JSON is UTF-8. So in this case the receiving server apparently is happy knowing that it's dealing with JSON and assumes that the encoding is UTF-8 by default, that's why it works with or without the header.

Does this encoding limit the characters that can be in the message body?

No. You can send anything you want in the header and the body. But, if the two don't match, you may get wrong results. If you specify in the header that the content is UTF-8 encoded but you're actually sending Latin1 encoded content, the receiver may produce garbage data, trying to interpret Latin1 encoded data as UTF-8. If of course you specify that you're sending Latin1 encoded data and you're actually doing so, then yes, you're limited to the 256 characters you can encode in Latin1.

I modified MC Shaman's code to fix the bug of single number having and appear before it

Just use a subquery with INNER JOIN, LEFT JOIN or smth else:

DELETE FROM m_productprice
WHERE m_product_id IN
(
  SELECT B.m_product_id
  FROM   m_productprice  B
    INNER JOIN m_product C 
    ON   B.m_product_id = C.m_product_id
  WHERE  C.upc = '7094' 
  AND    B.m_pricelist_version_id = '1000020'
)

to optimize the query,

• use NOT EXISTS instead of IN
• and WITH for large subqueries

I prefer using Symfony for this. Their libraries are pretty nice.

Use the The DomCrawler Component

Example:

$browser = new HttpBrowser(HttpClient::create());
$crawler = $browser->request('GET', 'example.com');
$class = $crawler->filter('.class')->first();

There's no ALTER COLUMN in sqlite.

I believe your only option is to:

• Rename the table to a temporary name
• Create a new table without the NOT NULL constraint
• Copy the content of the old table to the new one
• Remove the old table

This other Stackoverflow answer explains the process in details

To answer my own question, after posting on openssl mailing list got this:

Here is C code to convert from an OpenSSL public key to an OpenSSH public key. You can grab the code from this link and compile it yourself:

Here is what I did recently in PHP on one of my bigger systems:

1. User inputs newsletter text and selects the recipients (which generates a query to retrieve the email addresses for later).

2. Add the newsletter text and recipients query to a row in mysql table called *email_queue*

   • (The table email_queue has the columns "to" "subject" "body" "priority")

3. I created another script, which runs every minute as a cron job. It uses the SwiftMailer class. This script simply:

   • during business hours, sends all email with priority == 0

   • after hours, send other emails by priority

Depending on the hosts settings, I can now have it throttle using standard swiftmailers plugins like antiflood and throttle...

$mailer->registerPlugin(new Swift_Plugins_AntiFloodPlugin(50, 30));

and

$mailer->registerPlugin(new Swift_Plugins_ThrottlerPlugin( 100, Swift_Plugins_ThrottlerPlugin::MESSAGES_PER_MINUTE ));

etc, etc..

I have expanded it way beyond this pseudocode, with attachments, and many other configurable settings, but it works very well as long as your server is setup correctly to send email. (Probably wont work on shared hosting, but in theory it should...) Swiftmailer even has a setting

$message->setReturnPath

Which I now use to track bounces...

Happy Trails! (Happy Emails?)

Please enter domain nginx file :

nano /etc/nginx/sites-available/domain.set

Add to file this code

client_max_body_size 24000M;

If you get error use this command

nginx -t

Edit your phpmyadmin config.inc.php file and if you have Password, insert that in front of Password in following code:

$cfg['Servers'][$i]['verbose'] = 'localhost';
$cfg['Servers'][$i]['host'] = 'localhost';
$cfg['Servers'][$i]['port'] = '3306';
$cfg['Servers'][$i]['socket'] = '';
$cfg['Servers'][$i]['connect_type'] = 'tcp';
$cfg['Servers'][$i]['extension'] = 'mysqli';
$cfg['Servers'][$i]['auth_type'] = 'config';
$cfg['Servers'][$i]['user'] = '**your-root-username**';
$cfg['Servers'][$i]['password'] = '**root-password**';
$cfg['Servers'][$i]['AllowNoPassword'] = true;

This will handle paths with spaces:

find ./ -type f -name "*.php" -o -name "*.html" -exec tar uvf myarchives.tar {} +

Write the table name in the query editor select the name and press Alt+F1 and it will bring all the information of the table.

            get_template_part( 'template-parts/content', 'page' );

            // If comments are open or we have at least one comment, load up the comment template.
            if ( comments_open() || get_comments_number() ) {
                comments_template();
            }

            // End of the loop.
        endwhile;

<?php get_sidebar(); ?>
<?php get_footer(); ?>

If your input file has a fixed amount of columns separated by commas and you know in which columns are the strings it might be best to use the function

textscan()

Note that you can specify a format where you read up to a maximum number of characters in the string or until a delimiter (comma) is found.

You can do:

DataGridViewRow row = (DataGridViewRow)yourDataGridView.Rows[0].Clone();
row.Cells[0].Value = "XYZ";
row.Cells[1].Value = 50.2;
yourDataGridView.Rows.Add(row);

or:

DataGridViewRow row = (DataGridViewRow)yourDataGridView.Rows[0].Clone();
row.Cells["Column2"].Value = "XYZ";
row.Cells["Column6"].Value = 50.2;
yourDataGridView.Rows.Add(row);

Another way:

this.dataGridView1.Rows.Add("five", "six", "seven","eight");
this.dataGridView1.Rows.Insert(0, "one", "two", "three", "four");

You can't change the build output folder name with the current configuration options.

Moreover, you shouldn't. This is a part of the philosophy behind create-react-app: they say Convention over Configuration.

If you really need to rename your folder, I see two options:

1. Right after the build process finishes, write a command that copies the build folder content to another folder you want. For example you can try the copyfiles npm package, or anything similar.

2. You could try to eject create-react-app and tweak the configuration.

   If you aren’t satisfied with the build tool and configuration choices, you can eject at any time. This command will remove the single build dependency from your project.

   Instead, it will copy all the configuration files and the transitive dependencies (Webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except eject will still work, but they will point to the copied scripts so you can tweak them. At this point you’re on your own.

   However, it is important to note that this is a one-way operation. Once you eject, you can’t go back! You loose all future updates.

Therefore, I'd recommend you to not use a custom folder naming, if possible. Try to stick with the default naming. If not an option, try #1. If it still doesn't work for your specific use-case and you're really out of options - explore #2. Good luck!

To run the spring-boot application, need to follow some step.

1. Maven setup (ignore if already setup):

   a. Install maven from https://maven.apache.org/download.cgi

   b. Unzip maven and keep in C drive (you can keep any location. Path location will be changed accordingly).

   c. Set MAVEN_HOME in system variable.

   d. Set path for maven

2. Add Maven Plugin to POM.XML

   <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build>

3. Build Spring Boot Project with Maven

      maven package
   

   or

        mvn install / mvn clean install
   

4. Run Spring Boot app using Maven:

       mvn spring-boot:run
   

5. [optional] Run Spring Boot app with java -jar command

        java -jar target/mywebserviceapp-0.0.1-SNAPSHOT.jar
   

If you'd rather copy the properties:

var json1 = { value1: '1', value2: '2' };
var json2 = { value2: '4', value3: '3' };


function jsonConcat(o1, o2) {
 for (var key in o2) {
  o1[key] = o2[key];
 }
 return o1;
}

var output = {};
output = jsonConcat(output, json1);
output = jsonConcat(output, json2);

Output of above code is{ value1: '1', value2: '4', value3: '3' }

I figured out myself.

cmp calls ComputeBetasAndNuHat which returns a list which has objective as minusloglik

So I can change the function cmp to get this value.

Following what curl does internally for the request (via the method outlined in this answer to "Php - Debugging Curl") answers the question: No, it is not possible to use the curl_setopt call with CURLOPT_HTTPHEADER. The second call will overwrite the headers of the first call.

Instead the function needs to be called once with all headers:

$headers = array(
    'Content-type: application/xml',
    'Authorization: gfhjui',
);
curl_setopt($curlHandle, CURLOPT_HTTPHEADER, $headers);

Related (but different) questions are:

• How to send a header using a HTTP request through a curl call? (curl on the commandline)
• How to get an option previously set with curl_setopt()? (curl PHP extension)

There is a difference between hashCode() and identityHashCode() returns. It is possible that for two unequal (tested with ==) objects o1, o2 hashCode() can be the same. See the example below how this is true.

class SeeDifferences
{
    public static void main(String[] args)
    {
        String s1 = "stackoverflow";
        String s2 = new String("stackoverflow");
        String s3 = "stackoverflow";
        System.out.println(s1.hashCode());
        System.out.println(s2.hashCode());
        System.out.println(s3.hashCode());
        System.out.println(System.identityHashCode(s1));
        System.out.println(System.identityHashCode(s2));
        System.out.println(System.identityHashCode(s3));
        if (s1 == s2)
        {
            System.out.println("s1 and s2 equal");
        } 
        else
        {
            System.out.println("s1 and s2 not equal");
        }
        if (s1 == s3)
        {
            System.out.println("s1 and s3 equal");
        }
        else
        {
            System.out.println("s1 and s3 not equal");
        }
    }
}

According to the documentation NUM_ROWS is the "Number of rows in the table", so I can see how this might be confusing. There, however, is a major difference between these two methods.

This query selects the number of rows in MY_TABLE from a system view. This is data that Oracle has previously collected and stored.

select num_rows from all_tables where table_name = 'MY_TABLE'

This query counts the current number of rows in MY_TABLE

select count(*) from my_table

By definition they are difference pieces of data. There are two additional pieces of information you need about NUM_ROWS.

1. In the documentation there's an asterisk by the column name, which leads to this note:

   Columns marked with an asterisk (*) are populated only if you collect statistics on the table with the ANALYZE statement or the DBMS_STATS package.

   This means that unless you have gathered statistics on the table then this column will not have any data.

2. Statistics gathered in 11g+ with the default estimate_percent, or with a 100% estimate, will return an accurate number for that point in time. But statistics gathered before 11g, or with a custom estimate_percent less than 100%, uses dynamic sampling and may be incorrect. If you gather 99.999% a single row may be missed, which in turn means that the answer you get is incorrect.

If your table is never updated then it is certainly possible to use ALL_TABLES.NUM_ROWS to find out the number of rows in a table. However, and it's a big however, if any process inserts or deletes rows from your table it will be at best a good approximation and depending on whether your database gathers statistics automatically could be horribly wrong.

Generally speaking, it is always better to actually count the number of rows in the table rather then relying on the system tables.

here is simple solution for that problem, no needs for that 'cat walk' on keyboard, i mean regex :)) enjoy ^-^

user = input('Input: ') # user = 'foobar12345'
int_list, str_list = [], []

for item in user:
 try:
    item = int(item)  # searching for integers in your string
  except:
    str_list.append(item)
    string = ''.join(str_list)
  else:  # if there are integers i will add it to int_list but as str, because join function only can work with str
    int_list.append(str(item))
    integer = int(''.join(int_list))  # if you want it to be string just do z = ''.join(int_list)

final = [string, integer]  # you can also add it to dictionary d = {string: integer}
print(final)

string connectionString= ServerName + DatabaseName + SecurityType;
using (SqlConnection connection = new SqlConnection(connectionString))
using (SqlBulkCopy bulkCopy = new SqlBulkCopy(connection)) {
    connection.Open();
    bulkCopy.DestinationTableName = "TableName";
    try {
        bulkCopy.WriteToServer(dataTableName);
    } catch (Exception e) {
        Console.Write(e.Message);
    }
}

Please note that the structure of the database table and the table name should be the same or it will throw an exception.

Use properties file. Here is a good start: http://www.mkyong.com/java/java-properties-file-examples/

You can Use the tool : Eclipse Memory Analyzer Tool http://www.eclipse.org/mat/ .

It is very useful.

Use this:

return RedirectToAction("LogIn", "Account", new { area = "" });

This will redirect to the LogIn action in the Account controller in the "global" area.

It's using this RedirectToAction overload:

protected internal RedirectToRouteResult RedirectToAction(
    string actionName,
    string controllerName,
    Object routeValues
)

MSDN

As you said..

$Gender  = isset($_POST["gender"]); ' it returns a empty string 

because, you haven't mention method type either use POST or GET, by default it will use GET method. On the other side, you are trying to retrieve your value by using POST method, but in the form you haven't mentioned POST method. Which means miss-match method will result for empty.

Try this code..

<form name="signup_form"  action="./signup.php" onsubmit="return validateForm()"   method="post">
<table> 
  <tr> <td> First Name    </td><td> <input type="text" name="fname" size=10/></td></tr>
  <tr> <td> Last Name     </td><td> <input type="text" name="lname" size=10/></td></tr>
  <tr> <td> Your Email    </td><td> <input type="text" name="email" size=10/></td></tr>
  <tr> <td> Re-type Email </td><td> <input type="text" name="remail"size=10/></td></tr>
  <tr> <td> Password      </td><td> <input type="password" name="paswod" size=10/> </td></tr>
  <tr> <td> Gender        </td><td> <select name="gender">
  <option value="select">                Select </option>    
  <option value="male">   Male   </option>
  <option value="female"> Female </option></select></td></tr> 
  <tr> <td> <input type="submit" value="Sign up" id="signup"/> </td> </tr>
 </table>
 </form>

and on signup page

$Gender  = $_POST["gender"];

i'm sure.. now, you will get the value..

There is indeed a big difference, which you should keep in mind. setScale really set the scale of your number whereas round does round your number to the specified digits BUT it "starts from the leftmost digit of exact result" as mentioned within the jdk. So regarding your sample the results are the same, but try 0.0034 instead. Here's my note about that on my blog:

http://araklefeistel.blogspot.com/2011/06/javamathbigdecimal-difference-between.html

Edit: I totally misunderstood the question. In the browser, I would use setTimeout. If it was important that it ran in another thread, I would use Web Workers.

My random guess is: TV uses x264 codec which has a commercial license (otherwise TeamViewer would have to release their source code). At some point (more than 5 years ago), I recall main developer of x264 wrote an article about improvements he made for low delay encoding (if you delay by a few frames encoders can compress better), plus he mentioned some other improvements that were relevant for TeamViewer-like use. In that post he mentioned playing quake over video stream with no noticeable issues. Back then I was kind of sure who was the sponsor of these improvements, as TeamViewer was pretty much the only option at that time. x264 is an open source implementation of H264 video codec, and it's insanely good implementation, it's the best one. At the same time it's extremely well optimized. Most likely due to extremely good implementation of x264 you get much better results with TV at lower CPU load. AnyDesk and Chrome Remote Desk use libvpx, which isn't as good as x264 (optimization and video quality wise).

However, I don't think TeamView can beat microsoft's RDP. To me it's the best, however it works between windows PCs or from Mac to Windows only. TV works even from mobiles.

Update: article was written in January 2010, so that work was done roughly 10 years ago. Also, I made a mistake: he played call of duty, not quake. When you posted your question, if my guess is correct, TeamViewer had been using that work for 3 years. Read that blog post from web archive: x264: the best low-latency video streaming platform in the world. When I read the article back in 2010, I was sure that the "startup–which has requested not to be named" that the author mentions was TeamViewer.

A negative look ahead is a correct answer, but it can be written more cleanly like:

(\\)(?!.*\\)

This looks for an occurrence of \ and then in a check that does not get matched, it looks for any number of characters followed by the character you don't want to see after it. Because it's negative, it only matches if it does not find a match.

Vector and list aren't conceptually tied to C++. Similar structures can be implemented in C, just the syntax (and error handling) would look different. For example LodePNG implements a dynamic array with functionality very similar to that of std::vector. A sample usage looks like:

uivector v = {};
uivector_push_back(&v, 1);
uivector_push_back(&v, 42);
for(size_t i = 0; i < v.size; ++i)
    printf("%d\n", v.data[i]);
uivector_cleanup(&v);

As can be seen the usage is somewhat verbose and the code needs to be duplicated to support different types.

nothings/stb gives a simpler implementation that works with any types, but compiles only in C:

double *v = 0;
sb_push(v, 1.0);
sb_push(v, 42.0);
for(int i = 0; i < sb_count(v); ++i)
    printf("%g\n", v[i]);
sb_free(v);

A lot of C code, however, resorts to managing the memory directly with realloc:

void* newMem = realloc(oldMem, newSize);
if(!newMem) {
    // handle error
}
oldMem = newMem;

Note that realloc returns null in case of failure, yet the old memory is still valid. In such situation this common (and incorrect) usage leaks memory:

oldMem = realloc(oldMem, newSize);
if(!oldMem) {
    // handle error
}

Compared to std::vector and the C equivalents from above, the simple realloc method does not provide O(1) amortized guarantee, even though realloc may sometimes be more efficient if it happens to avoid moving the memory around.

This might be late as I think most of us are using BS4. This article explained all the questions you asked in a detailed and simple manner also includes what to do when. The detailed guide to use bs4 or bootstrap

If you are working with heavy queries, you better move the request for the latest row in the where clause. It is a lot faster and looks cleaner.

SELECT c.*,
FROM client AS c
LEFT JOIN client_calling_history AS cch ON cch.client_id = c.client_id
WHERE
   cch.cchid = (
      SELECT MAX(cchid)
      FROM client_calling_history
      WHERE client_id = c.client_id AND cal_event_id = c.cal_event_id
   )

Jon's disassemblies show, that the difference between the two versions is that the fast version uses a pair of registers (esi,edi) to store one of the local variables where the slow version doesn't.

The JIT compiler makes different assumptions regarding register use for code that contains a try-catch block vs. code which doesn't. This causes it to make different register allocation choices. In this case, this favors the code with the try-catch block. Different code may lead to the opposite effect, so I would not count this as a general-purpose speed-up technique.

In the end, it's very hard to tell which code will end up running the fastest. Something like register allocation and the factors that influence it are such low-level implementation details that I don't see how any specific technique could reliably produce faster code.

For example, consider the following two methods. They were adapted from a real-life example:

interface IIndexed { int this[int index] { get; set; } }
struct StructArray : IIndexed { 
    public int[] Array;
    public int this[int index] {
        get { return Array[index]; }
        set { Array[index] = value; }
    }
}

static int Generic<T>(int length, T a, T b) where T : IIndexed {
    int sum = 0;
    for (int i = 0; i < length; i++)
        sum += a[i] * b[i];
    return sum;
}
static int Specialized(int length, StructArray a, StructArray b) {
    int sum = 0;
    for (int i = 0; i < length; i++)
        sum += a[i] * b[i];
    return sum;
}

One is a generic version of the other. Replacing the generic type with StructArray would make the methods identical. Because StructArray is a value type, it gets its own compiled version of the generic method. Yet the actual running time is significantly longer than the specialized method's, but only for x86. For x64, the timings are pretty much identical. In other cases, I've observed differences for x64 as well.

Transition properties are comma delimited in all browsers that support transitions:

.nav a {
  transition: color .2s, text-shadow .2s;
}

ease is the default timing function, so you don't have to specify it. If you really want linear, you will need to specify it:

transition: color .2s linear, text-shadow .2s linear;

This starts to get repetitive, so if you're going to be using the same times and timing functions across multiple properties it's best to go ahead and use the various transition-* properties instead of the shorthand:

transition-property: color, text-shadow;
transition-duration: .2s;
transition-timing-function: linear;

To center a div, set it's width to some value and add margin: auto.

#partners .wrap {
    width: 655px;
    margin: auto;
}

EDIT, you want to center the div contents, not the div itself. You need to change display property of h2, ul and li to inline, and remove the float: left.

#partners li, ul, h2 {
    display: inline;
    float: none;
}

Then, they will be layed out like normal text elements, and aligned according to text-align property of their container, which is what you want.

The original variables you listed can be declared and assigned to the same value in a short line of code using destructuring assignment. The keywords let, const, and var can all be used for this type of assignment.

let [moveUp, moveDown, moveLeft, moveRight, mouseDown, touchDown] = Array(6).fill(false);

Edit: DTing's answer is more applicable to your question since it uses PIL, but I'll leave this up in case you want to know how to do it in numpy.

Here is a numpy/matplotlib solution that should work for N images (only color images) of any size/shape.

import numpy as np
import matplotlib.pyplot as plt

def concat_images(imga, imgb):
    """
    Combines two color image ndarrays side-by-side.
    """
    ha,wa = imga.shape[:2]
    hb,wb = imgb.shape[:2]
    max_height = np.max([ha, hb])
    total_width = wa+wb
    new_img = np.zeros(shape=(max_height, total_width, 3))
    new_img[:ha,:wa]=imga
    new_img[:hb,wa:wa+wb]=imgb
    return new_img

def concat_n_images(image_path_list):
    """
    Combines N color images from a list of image paths.
    """
    output = None
    for i, img_path in enumerate(image_path_list):
        img = plt.imread(img_path)[:,:,:3]
        if i==0:
            output = img
        else:
            output = concat_images(output, img)
    return output

Here is example use:

>>> images = ["ronda.jpeg", "rhod.jpeg", "ronda.jpeg", "rhod.jpeg"]
>>> output = concat_n_images(images)
>>> import matplotlib.pyplot as plt
>>> plt.imshow(output)
>>> plt.show()

You will get this error when you call any of the setXxx() methods on PreparedStatement, while the SQL query string does not have any placeholders ? for this.

For example this is wrong:

String sql = "INSERT INTO tablename (col1, col2, col3) VALUES (val1, val2, val3)";
// ...

preparedStatement = connection.prepareStatement(sql);
preparedStatement.setString(1, val1); // Fail.
preparedStatement.setString(2, val2);
preparedStatement.setString(3, val3);

You need to fix the SQL query string accordingly to specify the placeholders.

String sql = "INSERT INTO tablename (col1, col2, col3) VALUES (?, ?, ?)";
// ...

preparedStatement = connection.prepareStatement(sql);
preparedStatement.setString(1, val1);
preparedStatement.setString(2, val2);
preparedStatement.setString(3, val3);

Note the parameter index starts with 1 and that you do not need to quote those placeholders like so:

String sql = "INSERT INTO tablename (col1, col2, col3) VALUES ('?', '?', '?')";

Otherwise you will still get the same exception, because the SQL parser will then interpret them as the actual string values and thus can't find the placeholders anymore.

I faced the same issue and the complete solution is to set to false(uncheck) the "Automatically detect settings" checkbox from Lan Area Network( the same window as for Bypass proxy server for local address )

All the other answers talk about "upstream" (the branch you pull from).
But a local branch can push to a different branch than the one it pulls from.

master might not push to the remote tracking branch "origin/master".
The upstream branch for master might be origin/master, but it could push to the remote tracking branch origin/xxx or even anotherUpstreamRepo/yyy.
Those are set by branch.*.pushremote for the current branch along with the global remote.pushDefault value.

It is that remote-tracking branch which counts when seeking unpushed commits: the one that tracks the branch at the remote where the local branch would be pushed to.
The branch at the remote can be, again, origin/xxx or even anotherUpstreamRepo/yyy.

Git 2.5+ (Q2 2015) introduces a new shortcut for that: <branch>@{push}

See commit 29bc885, commit 3dbe9db, commit adfe5d0, commit 48c5847, commit a1ad0eb, commit e291c75, commit 979cb24, commit 1ca41a1, commit 3a429d0, commit a9f9f8c, commit 8770e6f, commit da66b27, commit f052154, commit 9e3751d, commit ee2499f [all from 21 May 2015], and commit e41bf35 [01 May 2015] by Jeff King (peff).
^{(Merged by Junio C Hamano -- gitster -- in commit c4a8354, 05 Jun 2015)}

Commit adfe5d0 explains:

sha1_name: implement @{push} shorthand

In a triangular workflow, each branch may have two distinct points of interest: the @{upstream} that you normally pull from, and the destination that you normally push to. There isn't a shorthand for the latter, but it's useful to have.

For instance, you may want to know which commits you haven't pushed yet:

git log @{push}..

Or as a more complicated example, imagine that you normally pull changes from origin/master (which you set as your @{upstream}), and push changes to your own personal fork (e.g., as myfork/topic).
You may push to your fork from multiple machines, requiring you to integrate the changes from the push destination, rather than upstream.
With this patch, you can just do:

git rebase @{push}

rather than typing out the full name.

Commit 29bc885 adds:

for-each-ref: accept "%(push)" format

Just as we have "%(upstream)" to report the "@{upstream}" for each ref, this patch adds "%(push)" to match "@{push}".
It supports the same tracking format modifiers as upstream (because you may want to know, for example, which branches have commits to push).

If you want to see how many commit your local branches are ahead/behind compared to the branch you are pushing to:

git for-each-ref --format="%(refname:short) %(push:track)" refs/heads

Everything that interacts with the UI must be called in the UI thread (unless it is a frozen object). To do that, you can use the dispatcher.

var disp = /* Get the UI dispatcher, each WPF object has a dispatcher which you can query*/
disp.BeginInvoke(DispatcherPriority.Normal,
        (Action)(() => /*Do your UI Stuff here*/));

I use BeginInvoke here, usually a backgroundworker doesn't need to wait that the UI updates. If you want to wait, you can use Invoke. But you should be careful not to call BeginInvoke to fast to often, this can get really nasty.

By the way, The BackgroundWorker class helps with this kind of taks. It allows Reporting changes, like a percentage and dispatches this automatically from the Background thread into the ui thread. For the most thread <> update ui tasks the BackgroundWorker is a great tool.

You declared them, but you didn't initialize them with a value. Add something like this:

int a = 0;

You have to change the line

product userFromJSON = mapper.readValue(userDataJSON, product.class);

to

product[] userFromJSON = mapper.readValue(userDataJSON, product[].class);

since you are deserializing an array (btw: you should start your class names with upper case letters as mentioned earlier). Additionally you have to create setter methods for your fields or mark them as public in order to make this work.

Edit: You can also go with Steven Schlansker's suggestion and use

List<product> userFromJSON =
        mapper.readValue(userDataJSON, new TypeReference<List<product>>() {});

instead if you want to avoid arrays.

You can use regular expressions for this purpose, but it's good to avoid extra exceptions when input string mismatches against regular expression.

First to avoid extra headache of escaping to regex pattern - we could just use function for that purpose:

String reStrEnding = Regex.Escape("-");

I know that this does not do anything - as "-" is the same as Regex.Escape("=") == "=", but it will make difference for example if character is @"\".

Then we need to match from begging of the string to string ending, or alternately if ending is not found - then match nothing. (Empty string)

Regex re = new Regex("^(.*?)" + reStrEnding);

If your application is performance critical - then separate line for new Regex, if not - you can have everything in one line.

And finally match against string and extract matched pattern:

String matched = re.Match(str).Groups[1].ToString();

And after that you can either write separate function, like it was done in another answer, or write inline lambda function. I've wrote now using both notations - inline lambda function (does not allow default parameter) or separate function call.

using System;
using System.Text.RegularExpressions;

static class Helper
{
    public static string GetUntilOrEmpty(this string text, string stopAt = "-")
    {
        return new Regex("^(.*?)" + Regex.Escape(stopAt)).Match(text).Groups[1].Value;
    }
}

class Program
{
    static void Main(string[] args)
    {
        Regex re = new Regex("^(.*?)-");
        Func<String, String> untilSlash = (s) => { return re.Match(s).Groups[1].ToString(); };

        Console.WriteLine(untilSlash("223232-1.jpg"));
        Console.WriteLine(untilSlash("443-2.jpg"));
        Console.WriteLine(untilSlash("34443553-5.jpg"));
        Console.WriteLine(untilSlash("noEnding(will result in empty string)"));
        Console.WriteLine(untilSlash(""));
        // Throws exception: Console.WriteLine(untilSlash(null));

        Console.WriteLine("443-2.jpg".GetUntilOrEmpty());
    }
}

Btw - changing regex pattern to "^(.*?)(-|$)" will allow to pick up either until "-" pattern or if pattern was not found - pick up everything until end of string.

Get the number of days between dates, inclusive.

public static List<Date> getDaysBetweenDates(Date startdate, Date enddate)
{
    List<Date> dates = new ArrayList<Date>();
    Calendar calendar = new GregorianCalendar();
    calendar.setTime(startdate);

    while (calendar.getTime().before(enddate))
    {
        Date result = calendar.getTime();
        dates.add(result);
        calendar.add(Calendar.DATE, 1);
    }
    return dates;
}

Decision tree:

1. Frameworks like Qt and SWT need native DLLs. So you have to ask yourself: Are all necessary platforms supported? Can you package the native DLLs with your app?

   See here, how to do this for SWT.

   If you have a choice here, you should prefer Qt over SWT. Qt has been developed by people who understand UI and the desktop while SWT has been developed out of necessity to make Eclipse faster. It's more a performance patch for Java 1.4 than a UI framework. Without JFace, you're missing many major UI components or very important features of UI components (like filtering on tables).

   If SWT is missing a feature that you need, the framework is somewhat hostile to extending it. For example, you can't extend any class in it (the classes aren't final, they just throw exceptions when the package of this.getClass() isn't org.eclipse.swt and you can't add new classes in that package because it's signed).

2. If you need a native, pure Java solution, that leaves you with the rest. Let's start with AWT, Swing, SwingX - the Swing way.

   AWT is outdated. Swing is outdated (maybe less so but not much work has been done on Swing for the past 10 years). You could argue that Swing was good to begin with but we all know that code rots. And that's especially true for UIs today.

   That leaves you with SwingX. After a longer period of slow progress, development has picked up again. The major drawback with Swing is that it hangs on to some old ideas which very kind of bleeding edge 15 years ago but which feel "clumsy" today. For example, the table views do support filtering and sorting but you still have to configure this. You'll have to write a lot of boiler plate code just to get a decent UI that feels modern.

   Another weak area is theming. As of today, there are a lot of themes around. See here for a top 10. But some are slow, some are buggy, some are incomplete. I hate it when I write a UI and users complain that something doesn't work for them because they selected an odd theme.

3. JGoodies is another layer on top of Swing, like SwingX. It tries to make Swing more pleasant to use. The web site looks great. Let's have a look at the tutorial ... hm ... still searching ... hang on. It seems that there is no documentation on the web site at all. Google to the rescue. Nope, no useful tutorials at all.

   I'm not feeling confident with a UI framework that tries so hard to hide the documentation from potential new fans. That doesn't mean JGoodies is bad; I just couldn't find anything good to say about it but that it looks nice.

4. JavaFX. Great, stylish. Support is there but I feel it's more of a shiny toy than a serious UI framework. This feeling roots in the lack of complex UI components like tree tables. There is a webkit-based component to display HTML.

   When it was introduced, my first thought was "five years too late." If your aim is a nice app for phones or web sites, good. If your aim is professional desktop application, make sure it delivers what you need.

5. Pivot. First time I heard about it. It's basically a new UI framework based on Java2D. So I gave it a try yesterday. No Swing, just tiny bit of AWT (new Font(...)).

   My first impression was a nice one. There is an extensive documentation that helps you getting started. Most of the examples come with live demos (Note: You must have Java enabled in your web browser; this is a security risk) in the web page, so you can see the code and the resulting application side by side.

   In my experience, more effort goes into code than into documentation. By looking at the Pivot docs, a lot of effort must have went into the code. Note that there is currently a bug which prevents some of the examples to work (PIVOT-858) in your browser.

   My second impression of Pivot is that it's easy to use. When I ran into a problem, I could usually solve it quickly by looking at an example. I'm missing a reference of all the styles which each component supports, though.

   As with JavaFX, it's missing some higher level components like a tree table component (PIVOT-306). I didn't try lazy loading with the table view. My impression is that if the underlying model uses lazy loading, then that's enough.

   Promising. If you can, give it a try.

As I understand POD (PlainOldData) is just a raw data - it does not need:

• to be constructed,
• to be destroyed,
• to have custom operators.
• Must not have virtual functions,
• and must not override operators.

How to check if something is a POD? Well, there is a struct for that called std::is_pod:

namespace std {
// Could use is_standard_layout && is_trivial instead of the builtin.
template<typename _Tp>
  struct is_pod
  : public integral_constant<bool, __is_pod(_Tp)>
  { };
}

(From header type_traits)

Reference:

• http://en.cppreference.com/w/cpp/types/is_pod
• http://en.wikipedia.org/wiki/Plain_old_data_structure
• http://en.wikipedia.org/wiki/Plain_Old_C++_Object
• File type_traits

here the problem is model binding if you specify a class then the model binding can understand it during the post if it an integer or string then you have to specify the [FromBody] to bind it properly.

make the following changes in FormMethod

using (@Html.BeginForm("myMethod", "Home", FormMethod.Post, new { id = @item.JobId })){

}

and inside your home controller for binding the string you should specify [FromBody]

using System.Web.Http;
[HttpPost]
public FileStreamResult myMethod([FromBody]string id)
{
     // Set a local variable with the incoming data
     string str = id;

}

FromBody is available in System.Web.Http. make sure you have the reference to that class and added it in the cs file.

In my own case I have the following error

Illegal mix of collations (utf8_general_ci,IMPLICIT) and (utf8_unicode_ci,IMPLICIT) for operation '='

$this->db->select("users.username as matric_no, CONCAT(users.surname, ' ', users.first_name, ' ', users.last_name) as fullname") ->join('users', 'users.username=classroom_students.matric_no', 'left') ->where('classroom_students.session_id', $session) ->where('classroom_students.level_id', $level) ->where('classroom_students.dept_id', $dept);

After weeks of google searching I noticed that the two fields I am comparing consists of different collation name. The first one i.e username is of utf8_general_ci while the second one is of utf8_unicode_ci so I went back to the structure of the second table and changed the second field (matric_no) to utf8_general_ci and it worked like a charm.

You propably have to write some JavaScript, because there is no way to estimate the height of all the users of the page.

var_dump($obj); 

If you want more info you can use a ReflectionClass:

http://www.phpro.org/manual/language.oop5.reflection.html

checked the program and the results are as,

p++;    // use it then move to next int position
++p;    // move to next int and then use it
++*p;   // increments the value by 1 then use it 
++(*p); // increments the value by 1 then use it
++*(p); // increments the value by 1 then use it
*p++;   // use the value of p then moves to next position
(*p)++; // use the value of p then increment the value
*(p)++; // use the value of p then moves to next position
*++p;   // moves to the next int location then use that value
*(++p); // moves to next location then use that value

This is the simplest solution:

SELECT quote FROM quotes ORDER BY RAND() 

Although it is not the most efficient. This one is a better solution.

Here's something I've just knocked up. It inspects the environment of the last-launched "gnome-session" process (DISPLAY is set correctly when VNC launches a session/window manager). Replace "gnome-session" with the name of whatever process your VNC server launches on startup.

PID=`pgrep -n -u $USER gnome-session`
if [ -n "$PID" ]; then
    export DISPLAY=`awk 'BEGIN{FS="="; RS="\0"}  $1=="DISPLAY" {print $2; exit}' /proc/$PID/environ`
    echo "DISPLAY set to $DISPLAY"
else
    echo "Could not set DISPLAY"
fi
unset PID

You should just be able to drop that in your .bashrc file.

For me this was simply calling route() on a named route that I had not created/created incorrectly. This caused the Forbidden error page.

Restarting the web server allowed proper Whoops! error to display:

Route [my-route-name] not defined.

Fixing the route name ->name('my-route-name') fixed the error.

This is on Laravel 5.5 & using wampserver.

Sorry.Though it is a bit late but hope it would help others as well . Always use the stdClass object.e.g

 $getvidids = $ci->db->query("SELECT * FROM videogroupids WHERE videogroupid='$videogroup'   AND used='0' LIMIT 10");

foreach($getvidids->result() as $key=>$myids)
{

  $vidid[$key] = $myids->videoid;  // better methodology to retrieve and store multiple records in arrays in loop
 }

SOLUTION After all this time, I managed to resolve the problem.

In Module: UserForms(Name).Userform_Initialize

This method works best to dynamically init the current UserForm

public class MyMap {

public static void main(String[] args) {

    Map<String, String> map1 = new HashMap<String, String>();
    map1.put("key1", "value1");
    map1.put("key2", "value2");
    map1.put("key3", "value3");
    map1.put(null, null);

    Map<String, String> map2 = new HashMap<String, String>();
    map2.put("key4", "value4");
    map2.put("key5", "value5");
    map2.put("key6", "value6");
    map2.put("key3", "replaced-value-of-key3-in-map2");
    // used only if map1 can be changes/updates with the same keys present in map2.
    map1.putAll(map2);

    // use below if you are not supposed to modify the map1.
    for (Map.Entry e : map2.entrySet())
        if (!map1.containsKey(e.getKey()))
            map1.put(e.getKey().toString(), e.getValue().toString());
    System.out.println(map1);
}}

I believe that you can make it scroll by using the trackball, which might be achieved programmatically through selection methods eventually, but it's just an idea. I know that the trackball method typically works, but as for the exact way to do this and make it work from code, I do not sure.
Hope that helps.

no need to worry for a directory lock guys.

Just you need to do is, If sqllite3 is not installed, type below command,

>sudo apt-get install sqlite3

Open SVN database by typing this command,

>sqlite3 .svn/wc.db 

Now just you need to do is to remove locks entries from SVN DB.

sqlite>  select * from wc_lock;
1|-1           
sqlite>  delete from wc_lock;
sqlite>  select * from wc_lock;
sqlite>  .q

Process Completed. You can work on your SVN repository, do commit, update, add, remove operations without issue.

If you don't need pure ES6 and can use Typescript, it has a nice enum:

https://www.typescriptlang.org/docs/handbook/enums.html

From the XML specification:

To allow attribute values to contain both single and double quotes, the apostrophe or single-quote character (') may be represented as "&apos;", and the double-quote character (") as "&quot;".

Just execute the query bellow:

DO $$ DECLARE
    r RECORD;
BEGIN
    FOR r IN (SELECT tablename FROM pg_tables WHERE schemaname = current_schema()) LOOP
        EXECUTE 'TRUNCATE TABLE ' || quote_ident(r.tablename) || '';
    END LOOP;
END $$;

Usually you can plug a Query's result (which is basically a table) as the FROM clause source of another query, so something like this will be written:

SELECT COUNT(*), SUM(SUBQUERY.AGE) from
(
  SELECT availables.bookdate AS Date, DATEDIFF(now(),availables.updated_at) as Age
  FROM availables
  INNER JOIN rooms
  ON availables.room_id=rooms.id
  WHERE availables.bookdate BETWEEN '2009-06-25' AND date_add('2009-06-25', INTERVAL 4 DAY) AND rooms.hostel_id = 5094
  GROUP BY availables.bookdate
) AS SUBQUERY

1. Open Visual Studio Installer from the Windows Start menu, or by selecting Tools > Get Tools and Features from the menu bar in Visual Studio.

   Visual Studio Installer opens.

2. Select the Individual components tab, and then scroll down to the Code tools category.

3. Select Class Designer and then select Modify.

The Class Designer component starts installing.

Another way, borrows a bit from Linkify but allows you to customize your handling.

Custom Span Class:

public class ClickSpan extends ClickableSpan {

    private OnClickListener mListener;

    public ClickSpan(OnClickListener listener) {
        mListener = listener;
    }

    @Override
    public void onClick(View widget) {
       if (mListener != null) mListener.onClick();
    }

    public interface OnClickListener {
        void onClick();
    }
}

Helper function:

public static void clickify(TextView view, final String clickableText, 
    final ClickSpan.OnClickListener listener) {

    CharSequence text = view.getText();
    String string = text.toString();
    ClickSpan span = new ClickSpan(listener);

    int start = string.indexOf(clickableText);
    int end = start + clickableText.length();
    if (start == -1) return;

    if (text instanceof Spannable) {
        ((Spannable)text).setSpan(span, start, end, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
    } else {
        SpannableString s = SpannableString.valueOf(text);
        s.setSpan(span, start, end, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
        view.setText(s);
    }

    MovementMethod m = view.getMovementMethod();
    if ((m == null) || !(m instanceof LinkMovementMethod)) {
        view.setMovementMethod(LinkMovementMethod.getInstance());
    }
}

Usage:

 clickify(textView, clickText,new ClickSpan.OnClickListener()
     {
        @Override
        public void onClick() {
            // do something
        }
    });

//the parsed time zone offset:
DateTimeFormatter dateFormat = DateTimeFormat.forPattern("yyyy-MM-dd'T'HH:mm:ss.SSSZ");
String fromDateTimeObj = "2011-01-03T12:00:00.000-0800";
DateTime fromDatetime = dateFormat.withOffsetParsed().parseDateTime(fromDateTimeObj);

sub domain is part of the domain, it's like subletting a room of an apartment. A records has to be setup on the dns for the domain e.g

mydomain.com has IP 123.456.789.999 and hosted with Godaddy. Now to get the sub domain

anothersite.mydomain.com

of which the site is actually on another server then

login to Godaddy and add an A record ^dnsimple anothersite.mydomain.com and point the IP to the other server 98.22.11.11

And that's it.

Here is how you generate a policy document using node and serverless

"use strict";

The issue is that the URL is being blocked from being created by Windows.

Steps to fix: Run command prompt as an administrator. Add the URL to the ACL

netsh http add urlacl url=http://+:8000/ServiceModelSamples/Service user=mylocaluser

My problem: Find indexes of list.

L = makelist() # Returns a list of different objects
La = np.array(L, dtype = object) # add dtype!
for c in chunks:
    L_ = La[c] # Since La is array, this works.

Another possible solution:

public String DecToHex(int dec){
  char[] hexDigits = {'0', '1', '2', '3', '4', '5', '6', '7', '8', '9',
              'A', 'B', 'C', 'D', 'E', 'F'};
  String hex = "";
  while (dec != 0) {
      int rem = dec % 16;
      hex = hexDigits[rem] + hex;
      dec = dec / 16;
  }
  return hex;
}

The bitmap constructor has resizing built in.

Bitmap original = (Bitmap)Image.FromFile("DSC_0002.jpg");
Bitmap resized = new Bitmap(original,new Size(original.Width/4,original.Height/4));
resized.Save("DSC_0002_thumb.jpg");

If you want control over interpolation modes see this post.

A TINYINT is an 8-bit integer value, a BIT field can store between 1 bit, BIT(1), and 64 bits, BIT(64). For a boolean values, BIT(1) is pretty common.

Note that if Log4j library is not installed, HttpClient (and therefore JWebUnit) will use logback. In this situation, create or edit logback.xml to include:

<configuration>
    <logger name="org.apache" level="WARN" />
    <logger name="httpclient" level="WARN" /> 
</configuration>

Setting the log level to WARN with Log4j using the package name org.apache.commons.httpclient in log4j.properties will not work as expected:

log4j.logger.org.apache.commons.httpclient=WARN

This is because the source for HttpClient (v3.1) uses the following log names:

public static Wire HEADER_WIRE = new Wire(LogFactory.getLog("httpclient.wire.header"));
public static Wire CONTENT_WIRE = new Wire(LogFactory.getLog("httpclient.wire.content"));

Change this:

 <div class=fetch_results>

To this:

 <div id="fetch_results">

Then the following should work:

$("#fetch_results input").each(function() {
      this.value = "";
  })?

If I read this correctly, it will be a requirement to use semicolons to end TSQL statements. http://msdn.microsoft.com/en-us/library/ms143729%28v=sql.120%29.aspx

EDIT: I found a plug-in for SSMS 2008R2 that will format your script and add the semicolons. I think it is still in beta though...

EDIT: I found an even better free tool/plugin called ApexSQL... http://www.apexsql.com/

 UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];

button.frame = CGRectMake(80.0, 210.0, 160.0, 40.0);

Slightly off topic from the original question, but it builds off Antoine’s idea and I thought it might help someone.

You can also make computed properties optional for structs with protocol extensions.

You can make a property on the protocol optional

protocol SomeProtocol {
    var required: String { get }
    var optional: String? { get }
}

Implement the dummy computed property in the protocol extension

extension SomeProtocol {
    var optional: String? { return nil }
}

And now you can use structs that do or don’t have the optional property implemented

struct ConformsWithoutOptional {
    let required: String
}

struct ConformsWithOptional {
    let required: String
    let optional: String?
}

I’ve also written up how to do optional properties in Swift protocols on my blog, which I’ll keep updated in case things change through the Swift 2 releases.

Add a new property called {previous} to $state on $stateChangeStart

$rootScope.$on( '$stateChangeStart', ( event, to, toParams, from, fromParams ) => {
    // Add {fromParams} to {from}
    from.params = fromParams;

    // Assign {from} to {previous} in $state
    $state.previous = from;
    ...
}

Now anywhere you need can use $state you will have previous available

previous:Object
    name:"route name"
    params:Object
        someParam:"someValue"
    resolve:Object
    template:"route template"
    url:"/route path/:someParam"

And use it like so:

$state.go( $state.previous.name, $state.previous.params );

You should be able to accomplish this by using location.href

if(window.location.hostname == "www.myweb.com"){
   window.location.href = window.location.href + "?single";
}

You can use the GSL. Some complete examples are given to demonstrate how to use it.

do use the links above. If you run into error "This update is not applicable to your computer. " then make sure you are in fact using the right file for your os. for example i tried running windows 2012 server from that link on windows 7 service pack 1 and I got the above error so be sure to use the right zip. If you don't know which os you have then go to start and system and it should pop right up This should be self explanatory but

After "AND" and after "OR" the QUERY has forgotten what it is all about.

I would also not know that it is about in any SQL / programming language.

if(SOMETHING equals "X" or SOMETHING equals "Y")

COLUMN NOT LIKE "A%" AND COLUMN NOT LIKE "B%"

For Microsoft Access

UPDATE TableA A
    INNER JOIN TableB B
    ON A.ID = B.ID
SET A.Name = B.Name

Coordinate[] coordinates = new Coordinate[3];
coordinates[0] = new Coordinate(102, 26);
coordinates[1] = new Coordinate(103, 25.12);
coordinates[2] = new Coordinate(104, 16.11);
CoordinateSequence coordinateSequence = new CoordinateArraySequence(coordinates);

Geometry geo = new LineString(coordinateSequence, geometryFactory);

CoordinateReferenceSystem wgs84 = DefaultGeographicCRS.WGS84;
CoordinateReferenceSystem cartesinaCrs = DefaultGeocentricCRS.CARTESIAN;

MathTransform mathTransform = CRS.findMathTransform(wgs84, cartesinaCrs, true);

Geometry geo1 = JTS.transform(geo, mathTransform);

Console.Read() takes a character and returns the ascii value of that character.So if you want to take the symbol that was entered by the user instead of its ascii value (ex:if input is 5 then symbol = 5, ascii value is 53), you have to parse it using int.parse() but it raises a compilation error because the return value of Console.Read() is already int type. So you can get the work done by using Console.ReadLine() instead of Console.Read() as follows.

int userInput = int.parse(Console.ReadLine());

here, the output of the Console.ReadLine() would be a string containing a number such as "53".By passing it to the int.Parse() we can convert it to int type.

void is a reserved JavaScript keyword. It evaluates the expression and always returns undefined.

It works in python 2.7 and 3.8:

from subprocess import Popen, PIPE
from shlex import split

proc = Popen(split('sudo -S %s' % command), bufsize=0, stdout=PIPE, stdin=PIPE, stderr=PIPE)
proc.stdin.write((password +'\n').encode()) # write as bytes
proc.stdin.flush() # need if not bufsize=0 (unbuffered stdin)

without .flush() password will not reach sudo if stdin buffered. In python 2.7 Popen by default used bufsize=0 and stdin.flush() was not needed.

For secure using, create password file in protected directory:

mkdir --mode=700 ~/.prot_dir
nano ~/.prot_dir/passwd.txt
chmod 600 ~/.prot_dir/passwd.txt 

at start your py-script read password from ~/.prot_dir/passwd.txt

with open(os.environ['HOME'] +'/.prot_dir/passwd.txt') as f:
    password = f.readline().rstrip()

You can obfuscate the javascript source all you want, but it will always be reverse-engineerable just by virtue of requiring all the source code to actually run on the client machine... the best option I can think of is having all your processing done with server-side code, and all the client code javascript does is send requests for processing to the server itself. Otherwise, anyone will always be able to keep track of all operations that the code is doing.

Someone mentioned base64 to keep strings safe. This is a terrible idea. Base64 is immediately recognizable by the types of people who would want to reverse engineer your code. The first thing they'll do is unencode it and see what it is.

You could just use the bound ng-model (answers[item.questID]) value itself in your ng-change method to detect if it has been checked or not.

Example:-

<input type="checkbox" ng-model="answers[item.questID]" 
     ng-change="stateChanged(item.questID)" /> <!-- Pass the specific id -->

and

$scope.stateChanged = function (qId) {
   if($scope.answers[qId]){ //If it is checked
       alert('test');
   }
}

There a few alternatives, both free and commercial. I haven't used any of them but in theory they should work:

• Iexpress (native windows tool)
• Quick Batch File Compiler (commercial)
• BoxedApp Packer
• "Advanced" Batch To EXE Converter" (freeware)

Most will require you to keep the batch file as main executable, and then bundle node.exe and your scripts.

Depending on your script, you also have the option to port it to JSDB, which supports an easy way to create executables by simply appending resources to it.

A third quasi-solution is to keep node somewhere like C:\utils and add this folder to your PATH environment variable. Then you can create .bat files in that dir that run node + your preferred scripts - I got coffeescript's coffee working on windows this way. This setup can be automated with a batch file, vb script or installer.

My preference, and I have no idea why this isn't already in jQuery:

$.fn.orElse = function(elseFunction) {
  if (!this.length) {
    elseFunction();
  }
};

Used like this:

$('#notAnElement').each(function () {
  alert("Wrong, it is an element")
}).orElse(function() {
  alert("Yup, it's not an element")
});

Or, as it looks in CoffeeScript:

$('#notAnElement').each ->
  alert "Wrong, it is an element"; return
.orElse ->
  alert "Yup, it's not an element"

This post shows a complete working HTML file as an example of triggering code to run when a tab is clicked. The .on() method is now the way that jQuery suggests that you handle events.

jQuery development history

To make something happen when the user clicks a tab can be done by giving the list element an id.

<li id="list">

Then referring to the id.

$("#list").on("click", function() {
 alert("Tab Clicked!");
});

Make sure that you are using a current version of the jQuery api. Referencing the jQuery api from Google, you can get the link here:

https://developers.google.com/speed/libraries/devguide#jquery

Here is a complete working copy of a tabbed page that triggers an alert when the horizontal tab 1 is clicked.

1. When async setting is set to false, a Synchronous call is made instead of an Asynchronous call.
2. When the async setting of the jQuery AJAX function is set to true then a jQuery Asynchronous call is made. AJAX itself means Asynchronous JavaScript and XML and hence if you make it Synchronous by setting async setting to false, it will no longer be an AJAX call.

As the error message says, non-default argument til should not follow default argument hgt.

Changing order of parameters (function call also be adjusted accordingly) or making hgt non-default parameter will solve your problem.

def a(len1, hgt=len1, til, col=0):

->

def a(len1, hgt, til, col=0):

UPDATE

Another issue that is hidden by the SyntaxError.

os.system accepts only one string parameter.

def a(len1, hgt, til, col=0):
    system('mode con cols=%s lines=%s' % (len1, hgt))
    system('title %s' % til)
    system('color %s' % col)

You may need to config the CORS at Spring Boot side. Please add below class in your Project.

import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.ServletRequest;

    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/**");
    }

    @Override
    public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) {
      HttpServletResponse response = (HttpServletResponse) res;
      HttpServletRequest request = (HttpServletRequest) req;
      System.out.println("WebConfig; "+request.getRequestURI());

}

UPDATE:

To append Token to each request you can create one Interceptor as below.

import { Injectable } from '@angular/core';
import { HttpEvent, HttpHandler, HttpInterceptor, HttpRequest } from '@angular/common/http';
import { Observable } from 'rxjs';

@Injectable()
export class AuthInterceptor implements HttpInterceptor {

  intercept(req: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {
    const token = window.localStorage.getItem('tokenKey'); // you probably want to store it in localStorage or something


    if (!token) {
      return next.handle(req);
    }

    const req1 = req.clone({
      headers: req.headers.set('Authorization', `${token}`),
    });

    return next.handle(req1);
  }

}

Example

For SendGrid - Django Specifically:

SendGrid Django Docs here

Set these variables in

settings.py

EMAIL_HOST = 'smtp.sendgrid.net'
EMAIL_HOST_USER = 'sendgrid_username'
EMAIL_HOST_PASSWORD = 'sendgrid_password'
EMAIL_PORT = 587
EMAIL_USE_TLS = True

in views.py

from django.core.mail import send_mail
send_mail('Subject here', 'Here is the message.', '[email protected]', ['[email protected]'], fail_silently=False)

If the items are numerically ordered, use the key() function to determine the index of the current item and compare it to the length. You'd have to use next() or prev() to cycle through items in a while loop instead of a for loop:

$length = sizeOf($arr);
while (key(current($arr)) != $length-1) {
    $v = current($arr); doSomething($v); //do something if not the last item
    next($myArray); //set pointer to next item
}

The difference is that Visibility.Hidden hides the control, but reserves the space it occupies in the layout. So it renders whitespace instead of the control. Visibilty.Collapsed does not render the control and does not reserve the whitespace. The space the control would take is 'collapsed', hence the name.

The exact text from the MSDN:

Collapsed: Do not display the element, and do not reserve space for it in layout.

Hidden: Do not display the element, but reserve space for the element in layout.

Visible: Display the element.

See: http://msdn.microsoft.com/en-us/library/system.windows.visibility.aspx

If you are like me just want to print a sequence within a lambda, without get the return value (list of None).

x = range(3)
from __future__ import print_function           # if not python 3
pra = lambda seq=x: map(print,seq) and None     # pra for 'print all'
pra()
pra('abc')

I hit the same problem while trying to open the solution on a network share in VS2013 Ultimate.

I corrected the problem by turning on

Control Panel -> Internet Options -> "Security" Tab -> Click "Local intranet", click on sites and make sure "Automatically detect intranet network" is ticked.

Why don't you simply use JavaScript's trim():

str.trim() //Will work everywhere irrespective of any framework.

For compatibility with <IE9 use:

if(typeof String.prototype.trim !== 'function') {
  String.prototype.trim = function() {
    return this.replace(/^\s+|\s+$/g, ''); 
  }
}

if a device has an SD card, you use:

or

JsonNode node = mapper.convertValue(object, JsonNode.class);

In create-react-app relative paths for images don't seem to work. Instead, you can import an image:

            <img src={logo} alt={"logo"}/>

Both the mongod (database server) and mongo (database client shell) programs are command line programs and each expects to be run in its own command line session. So, after starting the server (as you did with "./mongod") you should open a second command line session and run "./mongo" in it to give you a command line shell for talking to the server.

Here's a non-jQuery version that is considerably faster than both the jQuery .html() version and the .replace() version. This preserves all whitespace, but like the jQuery version, doesn't handle quotes.

function htmlEncode( html ) {
    return document.createElement( 'a' ).appendChild( 
        document.createTextNode( html ) ).parentNode.innerHTML;
};

Speed: http://jsperf.com/htmlencoderegex/17

Demo:

Output:

Script:

function htmlEncode( html ) {
    return document.createElement( 'a' ).appendChild( 
        document.createTextNode( html ) ).parentNode.innerHTML;
};

function htmlDecode( html ) {
    var a = document.createElement( 'a' ); a.innerHTML = html;
    return a.textContent;
};

document.getElementById( 'text' ).value = htmlEncode( document.getElementById( 'hidden' ).value );

//sanity check
var html = '<div>   &amp; hello</div>';
document.getElementById( 'same' ).textContent = 
      'html === htmlDecode( htmlEncode( html ) ): ' 
    + ( html === htmlDecode( htmlEncode( html ) ) );

HTML:

<input id="hidden" type="hidden" value="chalk    &amp; cheese" />
<input id="text" value="" />
<div id="same"></div>

It doesn't work on Ubuntu 16.04, it seems that some libraries have been forgotten in the python installation package on this one. You should use package manager instead.

Solution

Uninstall matplotlib from pip then install it again with apt-get

python 2:

sudo pip uninstall matplotlib
sudo apt-get install python-matplotlib

python 3:

sudo pip3 uninstall matplotlib
sudo apt-get install python3-matplotlib

If you need a multidimensional PHP array to be printed directly into the html page source code, and in an indented human-readable Javascript Object Notation (aka JSON) fashion, use this nice function I found in http://php.net/manual/en/function.json-encode.php#102091 coded by somebody nicknamed "bohwaz".

<?php

function json_readable_encode($in, $indent = 0, $from_array = false)
{
    $_myself = __FUNCTION__;
    $_escape = function ($str)
    {
        return preg_replace("!([\b\t\n\r\f\"\\'])!", "\\\\\\1", $str);
    };

    $out = '';

    foreach ($in as $key=>$value)
    {
        $out .= str_repeat("\t", $indent + 1);
        $out .= "\"".$_escape((string)$key)."\": ";

        if (is_object($value) || is_array($value))
        {
            $out .= "\n";
            $out .= $_myself($value, $indent + 1);
        }
        elseif (is_bool($value))
        {
            $out .= $value ? 'true' : 'false';
        }
        elseif (is_null($value))
        {
            $out .= 'null';
        }
        elseif (is_string($value))
        {
            $out .= "\"" . $_escape($value) ."\"";
        }
        else
        {
            $out .= $value;
        }

        $out .= ",\n";
    }

    if (!empty($out))
    {
        $out = substr($out, 0, -2);
    }

    $out = str_repeat("\t", $indent) . "{\n" . $out;
    $out .= "\n" . str_repeat("\t", $indent) . "}";

    return $out;
}

?>       

DECLARE @uuid VARCHAR(50)
SET @uuid = 'a89b1acd95016ae6b9c8aabb07da2010'
SELECT  CAST(
        SUBSTRING(@uuid, 1, 8) + '-' + SUBSTRING(@uuid, 9, 4) + '-' + SUBSTRING(@uuid, 13, 4) + '-' +
        SUBSTRING(@uuid, 17, 4) + '-' + SUBSTRING(@uuid, 21, 12)
        AS UNIQUEIDENTIFIER)

All solutions here doesn't really bind the model to the input because you will have to change back the dateAsString to be saved as date in your object (in the controller after the form will be submitted).

If you don't need the binding effect, but just to show it in the input,

a simple could be:

<input type="date" value="{{ item.date | date: 'yyyy-MM-dd' }}" id="item_date" />

Then, if you like, in the controller, you can save the edited date in this way:

  $scope.item.date = new Date(document.getElementById('item_date').value).getTime();

be aware: in your controller, you have to declare your item variable as $scope.item in order for this to work.

• Open up windows explorer

• Tools -> Folder Options.

• File Types Tab

• Select the Folder file type

• Click Advanced

• Click New

• For the Action type what ever you want the context menu to display, I used Command Prompt.

• For the Application used to perform the action use c:\windows\system32\cmd.exe (note on win2k you will want to specify the winnt directory instead of the windows directory)

It's probably easiest to create your query object directly as:

  Test.find({
      $and: [
          { $or: [{a: 1}, {b: 1}] },
          { $or: [{c: 1}, {d: 1}] }
      ]
  }, function (err, results) {
      ...
  }

But you can also use the Query#and helper that's available in recent 3.x Mongoose releases:

  Test.find()
      .and([
          { $or: [{a: 1}, {b: 1}] },
          { $or: [{c: 1}, {d: 1}] }
      ])
      .exec(function (err, results) {
          ...
      });

Try using this code:

var milisegundos = parseInt(data.replace("/Date(", "").replace(")/", ""));
var newDate = new Date(milisegundos).toLocaleDateString("en-UE");

Enjoy it!

Non-empty secondary constructor for data class in Kotlin:

data class ChemicalElement(var name: String,
                           var symbol: String,
                           var atomicNumber: Int,
                           var atomicWeight: Double,
                           var nobleMetal: Boolean?) {

    constructor(): this("Silver",
                        "Ag", 
                        47,
                        107.8682,
                        true)
}

fun main() {
    var chemicalElement = ChemicalElement()
    println("RESULT: ${chemicalElement.symbol} means ${chemicalElement.name}")
    println(chemicalElement)
}

// RESULT: Ag means Silver
// ChemicalElement(name=Silver, symbol=Ag, atomicNumber=47, atomicWeight=107.8682, nobleMetal=true)

Empty secondary constructor for data class in Kotlin:

data class ChemicalElement(var name: String,
                           var symbol: String,
                           var atomicNumber: Int,
                           var atomicWeight: Double,
                           var nobleMetal: Boolean?) {

    constructor(): this("",
                        "", 
                        -1,
                        0.0,
                        null)
}

fun main() {
    var chemicalElement = ChemicalElement()
    println(chemicalElement)
}

// ChemicalElement(name=, symbol=, atomicNumber=-1, atomicWeight=0.0, nobleMetal=null)

Here is what works for me:

[1, "", 2, "hello", nil].reject(&:blank?)

output:

[1, 2, "hello"]

a <div> can be focused if it has a tabindex attribute. (the value can be set to -1)

For example:

$("#focus_point").attr("tabindex",-1).focus();

In addition, consider setting outline: none !important; so it displayed without a focus rectangle.

var element = $("#focus_point");
element.css('outline', 'none !important')
       .attr("tabindex", -1)
       .focus();

Set the datasource property to an empty string then call the Clear method.

You can also check this out. If you are using this method, then use the parse function to get values from Mongo Database:

db.getCollection('user').find({
    createdOn: {
        $gt: ISODate("2020-01-01T00:00:00.000Z"),
        $lt: ISODate("2020-03-01T00:00:00.000Z")
    }
})

I had a hard time making this work too, the solution for me was to use both hyui and konstantin answers,

class ExampleTask extends AsyncTask<String, String, String> {

// Your onPreExecute method.

@Override
protected String doInBackground(String... params) {
    // Your code.
    if (condition_is_true) {
        this.publishProgress("Show the dialog");
    }
    return "Result";
}

@Override
protected void onProgressUpdate(String... values) {

    super.onProgressUpdate(values);
    YourActivity.this.runOnUiThread(new Runnable() {
       public void run() {
           alertDialog.show();
       }
     });
 }

}

My issue was having multiple AWS credentials; default and dev. Since I was trying to deploy to dev this worked:

$(aws ecr get-login --no-include-email --region eu-west-1 --profile dev | sed 's|https://||')

From the documentation for strtotime():

Dates in the m/d/y or d-m-y formats are disambiguated by looking at the separator between the various components: if the separator is a slash (/), then the American m/d/y is assumed; whereas if the separator is a dash (-) or a dot (.), then the European d-m-y format is assumed.

In your date string, you have 12-16-2013. 16 isn't a valid month, and hence strtotime() returns false.

Since you can't use DateTime class, you could manually replace the - with / using str_replace() to convert the date string into a format that strtotime() understands:

$date = '2-16-2013';
echo date('Y-m-d', strtotime(str_replace('-','/', $date))); // => 2013-02-16

For simplicity and well structured sake, use SpringMVC. It's just so simple.

@RequestMapping("/carlist.json")
public @ResponseBody List<String> getCarList() {
    return carService.getAllCars();
}

One way you could do it is have a file with the username and pass directly under it. Then uses the Scanner class and when you create it, make the file the parameter for the Scanner. Then use the methods hasNext(); and nextLine to verify the username and password;

String user;
String pass;

Scanner scan = new Scanner(new File("File.txt"));

while(scan.hasNext){ //While the file still has more lines remaining
     if(scan.nextLine() == user){
          if(scan.nextLine == pass){
                   lblDisplay.setText("Credentials Accepted.");
          }
          else{
               lblDisplay.setText("Please try again.");
          }
     }
}

For your example query, the only possible value greater than 2 and less than 4 is 3, so we simplify:

GROUP BY meetingID
HAVING COUNT(caseID) = 3

In your general case:

GROUP BY meetingID
HAVING COUNT(caseID) > x AND COUNT(caseID) < 7

Or (possibly easier to read?),

GROUP BY meetingID
HAVING COUNT(caseID) BETWEEN x+1 AND 6

It was moved to functools.

/<b>(.*?)<\/b>/g

Add g (global) flag after:

/<b>(.*?)<\/b>/g.exec(str)
             //^-----here it is 

However if you want to get all matched elements, then you need something like this:

var str = "<b>Bob</b>, I'm <b>20</b> years old, I like <b>programming</b>.";

var result = str.match(/<b>(.*?)<\/b>/g).map(function(val){
   return val.replace(/<\/?b>/g,'');
});
//result -> ["Bob", "20", "programming"] 

If an element has attributes, regexp will be:

/<b [^>]+>(.*?)<\/b>/g.exec(str)

%zd works for NSIntegers (%tu for NSUInteger) with no casts and no warnings on both 32-bit and 64-bit architectures. I have no idea why this is not the "recommended way".

NSString *string = [NSString stringWithFormat:@"%zd", month];

If you're interested in why this works see this question.

Is Ruby pass by reference or by value?

Ruby is pass-by-reference. Always. No exceptions. No ifs. No buts.

Here is a simple program which demonstrates that fact:

def foo(bar)
  bar.object_id
end

baz = 'value'

puts "#{baz.object_id} Ruby is pass-by-reference #{foo(baz)} because object_id's (memory addresses) are always the same ;)"

=> 2279146940 Ruby is pass-by-reference 2279146940 because object_id's (memory addresses) are always the same ;)

def bar(babar)
  babar.replace("reference")
end

bar(baz)

puts "some people don't realize it's reference because local assignment can take precedence, but it's clearly pass-by-#{baz}"

=> some people don't realize it's reference because local assignment can take precedence, but it's clearly pass-by-reference

I had trouble with a crashing program *cough PHP cough* Upon crash the shell it was ran in reports the crash reason, Segmentation fault (core dumped)

To avoid this output not getting logged, the command can be run in a subshell that will capture and direct these kind of output:

sh -c 'your_command' > your_stdout.log 2> your_stderr.err
# or
sh -c 'your_command' > your_stdout.log 2>&1

In my case, I have double-clicked a Visual 2013 sln file and Visual 2012 opened (instead of Visual 2013). Trying to compile with Visual 2012, a project that has the Platform Toolset set to "v120" showed the error above mentioned. However, reopening the sln with Visual 2013, the Platform Toolset was set to "Visual Studio 2013 (v120)" - please note the complete name this time -, actually did the job for me. The project compiles well now.

It looks to me like it's because you are instantiating your TabListener every time... so the system is recreating your fragment from the savedInstanceState and then you are doing it again in your onCreate.

You should wrap that in a if(savedInstanceState == null) so it only fires if there is no savedInstanceState.

Then solution will be the following.

HTML

<div class="parent">
    <div class="child"></div>
</div>

CSS

.parent{
        width: 960px;
        margin: auto;
        height: 100vh
    }
    .child{
        position: absolute;
        width: 100vw
    }

A simple way to fix this is to change the XAMP port to a random number.

Regarding [Console]::WriteLine() - you should use it if you are going to use pipelines in CMD (not in powershell). Say you want your ps1 to stream a lot of data to stdout, and some other utility to consume/transform it. If you use Write-Host in the script it will be much slower.

How about adding line-height ?

#abc{
  font:Verdana, Geneva, sans-serif;
  font-size:18px;
  text-align:left;
  background-color:#0F0;
  height:50px;
  vertical-align:middle;
  line-height: 45px;
}

Fiddle, line-height

Or padding on #abc. This is the result with padding

Update

Add in your css :

#abc img{
   vertical-align: middle;
}

The result. Hope this what you looking for.

Having gone through a ridiculous amount of time trying to solve one of these, and I definitely can see where most of these answers could be correct in some cases, my situation was not all that uncommon.

I was trying to deploy to the app store to test with TestFlight. A previous developer, no longer part of the project or company, had created the IOS Distribution Certificate. What xcode was trying to tell me was that yes, the certificate was in the member center, but dude you totally can't use it because it's not yours. I didn't have the private key needed to sign with it and no amount of refreshes, restarts, revokes were going to help me. You need a developer and distribution certificate to upload to the app store.

The solution was to create a new production distribution certificate in the member center, using a new signing request from my keychain. This process is documented well and described while you create the cert online. Once done, refresh your account in xcode to download to your keychain and you will be golden. I hope this helps somebody!

You can do this using Input.setSelectionRange, part of the Range API for interacting with text selections and the text cursor:

var searchInput = $('#Search');

// Multiply by 2 to ensure the cursor always ends up at the end;
// Opera sometimes sees a carriage return as 2 characters.
var strLength = searchInput.val().length * 2;

searchInput.focus();
searchInput[0].setSelectionRange(strLength, strLength);

([FromBody] IDictionary<string,object> data)

The values of form elements including type='hidden' are submitted to the server when the form is posted. input type="hidden" values are not visible in the page. Maintaining User IDs in hidden fields, for example, is one of the many uses.

SO uses a hidden field for the upvote click.

<input value="16293741" name="postId" type="hidden">

Using this value, the server-side script can store the upvote.

There is a new and better way to share data between activities, and it is LiveData. Notice in particular this quote from the Android developer's page:

The fact that LiveData objects are lifecycle-aware means that you can share them between multiple activities, fragments, and services. To keep the example simple, you can implement the LiveData class as a singleton

The implication of this is huge - any model data can be shared in a common singleton class inside a LiveData wrapper. It can be injected from the activities into their respective ViewModel for the sake of testability. And you no longer need to worry about weak references to prevent memory leaks.

Based on the accepted response by tiago, here is a small generic function that exports a numpy array to an image having the same resolution as the array:

import matplotlib.pyplot as plt
import numpy as np

def export_figure_matplotlib(arr, f_name, dpi=200, resize_fact=1, plt_show=False):
    """
    Export array as figure in original resolution
    :param arr: array of image to save in original resolution
    :param f_name: name of file where to save figure
    :param resize_fact: resize facter wrt shape of arr, in (0, np.infty)
    :param dpi: dpi of your screen
    :param plt_show: show plot or not
    """
    fig = plt.figure(frameon=False)
    fig.set_size_inches(arr.shape[1]/dpi, arr.shape[0]/dpi)
    ax = plt.Axes(fig, [0., 0., 1., 1.])
    ax.set_axis_off()
    fig.add_axes(ax)
    ax.imshow(arr)
    plt.savefig(f_name, dpi=(dpi * resize_fact))
    if plt_show:
        plt.show()
    else:
        plt.close()

As said in the previous reply by tiago, the screen DPI needs to be found first, which can be done here for instance: http://dpi.lv

I've added an additional argument resize_fact in the function which which you can export the image to 50% (0.5) of the original resolution, for instance.

There's a couple ways of doing this. As long as the WAR file is expanded (a set of files instead of one .war file), you can use this API:

ServletContext context = getContext();
String fullPath = context.getRealPath("/WEB-INF/test/foo.txt");

http://tomcat.apache.org/tomcat-5.5-doc/servletapi/javax/servlet/ServletContext.html#getRealPath(java.lang.String)

That will get you the full system path to the resource you are looking for. However, that won't work if the Servlet Container never expands the WAR file (like Tomcat). What will work is using the ServletContext's getResource methods.

ServletContext context = getContext();
URL resourceUrl = context.getResource("/WEB-INF/test/foo.txt");

or alternatively if you just want the input stream:

InputStream resourceContent = context.getResourceAsStream("/WEB-INF/test/foo.txt");

http://tomcat.apache.org/tomcat-5.5-doc/servletapi/javax/servlet/ServletContext.html#getResource(java.lang.String)

The latter approach will work no matter what Servlet Container you use and where the application is installed. The former approach will only work if the WAR file is unzipped before deployment.

EDIT: The getContext() method is obviously something you would have to implement. JSP pages make it available as the context field. In a servlet you get it from your ServletConfig which is passed into the servlet's init() method. If you store it at that time, you can get your ServletContext any time you want after that.

Pim's answer is very helpful. In my case, I have to use

Expires / Max-Age: "Session"

If it is a dateTime, even it is not expired, it still won't send the cookie to the backend:

Expires / Max-Age: "Thu, 21 May 2020 09:00:34 GMT"

Hope it is helpful for future people who may meet same issue.

Using Android's built in method

If you want every column and every row, then just pass in null for the SQLiteDatabase column and selection parameters.

Cursor cursor = db.query(TABLE_NAME, null, null, null, null, null, null, null);

More details

The other answers use rawQuery, but you can use Android's built in SQLiteDatabase. The documentation for query says that you can just pass in null to the selection parameter to get all the rows.

selection Passing null will return all rows for the given table.

And while you can also pass in null for the column parameter to get all of the columns (as in the one-liner above), it is better to only return the columns that you need. The documentation says

columns Passing null will return all columns, which is discouraged to prevent reading data from storage that isn't going to be used.

Example

SQLiteDatabase db = mHelper.getReadableDatabase();
String[] columns = {
        MyDatabaseHelper.COLUMN_1,
        MyDatabaseHelper.COLUMN_2,
        MyDatabaseHelper.COLUMN_3};
String selection = null; // this will select all rows
Cursor cursor = db.query(MyDatabaseHelper.MY_TABLE, columns, selection,
        null, null, null, null, null);
