I have faced it on 04/2020. These are the options that I tried and the last solution get me through.

Problem:

Requests module works fine when I use in Spyder IDE but when I try to execute the script in windows it fails with SSL error. It works fine for HTTP requests but for HTTPS requests i got SSL error.

1. I tired with Veify=True, False , also with Certs. Same error.
2. Removed Certifi - conda remove certifi - Did not work Updated
3. openssl , certifi - Still same error ( Refer : https://github.com/ContinuumIO/anaconda-issues/issues/494) Added
4. the path variables - Same error
5. Created new environment in Anaconda - same error

Solution that fixed it:

Solution from: https://github.com/conda/conda/issues/8273

I have copied the following files from Anaconda3\Library\bin to \Anaconda3\DLL

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

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.

See also:

• https://github.com/webpack/webpack/issues/3216
• https://angular.io/guide/build#configure-size-budgets
• Performance Budgets (Keep Request Counts Low And File Sizes Small)

Only changing the settings with the following command did not work in my environment:

curl -XPUT -H "Content-Type: application/json" http://localhost:9200/_all/_settings -d '{"index.blocks.read_only_allow_delete": null}'

I had to also ran the Force Merge API command:

curl -X POST "localhost:9200/my-index-000001/_forcemerge?pretty"

ref: Force Merge API

In this case , this code

{<td><span onClick={this.toggle()}>Details</span></td>}

causes toggle function to call immediately and re render it again and again thus making infinite calls.

so passing only the reference to that toggle method will solve the problem.

so ,

{<td><span onClick={this.toggle}>Details</span></td>}

will be the solution code.

If you want to use the () , you should use an arrow function like this

{<td><span onClick={()=> this.toggle()}>Details</span></td>}

In case you want to pass parameters you should choose the last option and you can pass parameters like this

{<td><span onClick={(arg)=>this.toggle(arg)}>Details</span></td>}

In the last case it doesn't call immediately and don't cause the re render of the function, hence avoiding infinite calls.

Your problem is that you are naming your component class Date. When you call new Date() within your class, it won't create an instance of the Date you expect it to create (which is likely this Date)- it will try to create an instance of your component class. Then the constructor will try to create another instance, and another instance, and another instance... Until you run out of stack space and get the error you're seeing.

If you want to use Date within your class, try naming your class something different such as Calendar or DateComponent.

The reason for this is how JavaScript deals with name scope: Whenever you create a new named entity, if there is already an entity with that name in scope, that name will stop referring to the previous entity and start referring to your new entity. So if you use the name Date within a class named Date, the name Date will refer to that class and not to any object named Date which existed before the class definition started.

The previous answer is pretty good, but I also wanted to mention that there is a fixed layout equivalent for grids, you just need to write minmax(0, 1fr) instead of 1fr as your track size.

Some additional advice for Windows(10) users:

1. If you are using Anaconda Prompt/PowerShell for the first time, type "Anaconda" in the search field of your Windows task bar and you will see the suggested software.
2. Make sure to open the Anaconda prompt as administrator.
3. Always navigate to your user directory or the directory with your Jupyter Notebook files first before running the command. Otherwise you might end up somewhere in your system files and be confused by an unfamiliar file tree.

The correct way to open Jupyter notebook with new data limit from the Anaconda Prompt on my own Windows 10 PC is:

(base) C:\Users\mobarget\Google Drive\Jupyter Notebook>jupyter notebook --NotebookApp.iopub_data_rate_limit=1.0e10

I deleted

node_modules

and then reinstalled by

npm install

It worked for me

I had a similar experience with Chai-Webdriver for Selenium. I added await to the assertion and it fixed the issue:

Example using Cucumberjs:

Then(/I see heading with the text of Tasks/, async function() {
    await chai.expect('h1').dom.to.contain.text('Tasks');
});

I encountered this issue when trying to debug with VSCode, so just wanted to add this is how you can add the argument to your debug setup.

You can add it to the runtimeArgs property of your config in launch.json.

See example below.

{
"version": "0.2.0",
"configurations": [{
        "type": "node",
        "request": "launch",
        "name": "Launch Program",
        "program": "${workspaceRoot}\\server.js"
    },
    {
        "type": "node",
        "request": "launch",
        "name": "Launch Training Script",
        "program": "${workspaceRoot}\\training-script.js",
        "runtimeArgs": [
            "--max-old-space-size=4096"
        ]
    }
]}

Also in Spring boot 1.4, you can add following lines to your application.properties to set the file size limit:

spring.http.multipart.max-file-size=128KB
spring.http.multipart.max-request-size=128KB

for spring boot 2.x and above its

spring.servlet.multipart.max-file-size=10MB
spring.servlet.multipart.max-request-size=10MB

Worked for me. Source: https://spring.io/guides/gs/uploading-files/

UPDATE:

Somebody asked the differences between the two properties.

Below are the formal definitions:

MaxFileSize: The maximum size allowed for uploaded files, in bytes. If the size of any uploaded file is greater than this size, the web container will throw an exception (IllegalStateException). The default size is unlimited.

MaxRequestSize: The maximum size allowed for a multipart/form-data request, in bytes. The web container will throw an exception if the overall size of all uploaded files exceeds this threshold. The default size is unlimited.

To explain each:

MaxFileSize: The limit for a single file to upload. This is applied for the single file limit only.

MaxRequestSize: The limit for the total size of all files in a single upload request. This checks the total limit. Let's say you have two files a.txt and b.txt for a single upload request. a.txt is 5kb and b.txt is 7kb so the MaxRequestSize should be above 12kb.

For me Upgrading Gradle works.Look for update at Android Website then add it in your build.gradle (Project) like this

 dependencies {
        classpath 'com.android.tools.build:gradle:2.2.0-alpha4'   
          ....
    }

then sync project with gradle file plus it might be happened sometimes because of java.exe (in my case) just force kill java.exe from task manager in windows then re run program

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 a reference type and always nullable, you don't need to do anything special. Specifying that a type is nullable is necessary only for value types.

componentWillReceiveProps is depcricated since react 16: use getDerivedStateFromProps instead

If I understand correctly, you have a parent component that is passing start_time down to the ModalBody component which assigns it to its own state? And you want to update that time from the parent, not a child component.

React has some tips on dealing with this scenario. (Note, this is an old article that has since been removed from the web. Here's a link to the current doc on component props).

Using props to generate state in getInitialState often leads to duplication of "source of truth", i.e. where the real data is. This is because getInitialState is only invoked when the component is first created.

Whenever possible, compute values on-the-fly to ensure that they don't get out of sync later on and cause maintenance trouble.

Basically, whenever you assign parent's props to a child's state the render method isn't always called on prop update. You have to invoke it manually, using the componentWillReceiveProps method.

componentWillReceiveProps(nextProps) {
  // You don't have to do this check first, but it can help prevent an unneeded render
  if (nextProps.startTime !== this.state.startTime) {
    this.setState({ startTime: nextProps.startTime });
  }
}

I solved this issue to update .htaccess file inside your workspace (like C:\xampp\htdocs\Nayan\.htaccess in my case).

Just update or add this php_value max_execution_time 300 line before # END WordPress. Then save the file and try to install again.

If the error occurs again, you can maximize the value from 300 to 600.

Execution is not related to laravel go to the php.ini file In php.ini file set max_execution_time=360 (time may be variable depends on need) if you want to increase execution of a specific page then write ini_set('max_execution_time',360) at top of page

otherwise in htaccess php_value max_execution_time 360

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.

I stopped the IIS Worker Process (in task manager), and then started the IIS again. It worked.

Either one of the below three options gets rid of the message (but for different reasons and with different side-effects I suppose):

1. exclude the node_modules directory or explicitly include the directory where your app resides (which presumably does not contain files in excess of 100KB)
2. set the Babel option compact to true (actually any value other than "auto")
3. set the Babel option compact to false (see above)

#1 in the above list can be achieved by either excluding the node_modules directory or be explicitly including the directory where your app resides.

E.g. in webpack.config.js:

let path = require('path');
....
module: {
     loaders: [
          ...
          loader: 'babel',
          exclude: path.resolve(__dirname, 'node_modules/')

... or by using include: path.resolve(__dirname, 'app/') (again in webpack.config.js).

#2 and #3 in the above list can be accomplished by the method suggested in this answer or (my preference) by editing the .babelrc file. E.g.:

$ cat .babelrc 
{
    "presets": ["es2015", "react"],
    "compact" : true
}

Tested with the following setup:

$ npm ls --depth 0 | grep babel

+-- [email protected]
+-- [email protected]
+-- [email protected]

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)

With the aws dynamodb cli you can get it via scan as follows:

aws dynamodb scan --table-name <TABLE_NAME> --select "COUNT"

The response will look similar to this:

{
    "Count": 123,
    "ScannedCount": 123,
    "ConsumedCapacity": null
}

notice that this information is in real time in contrast to the describe-table api

I tried majority of the solutions provided in this answer blog, however none of them worked, I had this ssl certificant error as I try to install python packages.

I succeed by following command:

python -m pip install PACKAGENAME --trusted-host=pypi.python.org --trusted-host=pypi.org --trusted-host=files.pythonhosted.org 

I'm using Android Studio 3.4 and the only thing that worked for me was to remove the following lines from my build.gradle file:

minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

Because Android Studio 3.4 is using R8 in full mode and is not direct compatible with Proguard

I think that you should make the reference to your config file

26399:C 16 Jan 08:51:13.413 # Warning: no config file specified, using the default config. In order to specify a config file use ./redis-server /path/to/redis.conf

./redis-server /path/to/redis-stable/redis.conf

PhpStorm 2020

1. Help -> Edit Custom Properties.
2. File will open in Editor. Paste the section below to the file.

 #---------------------------------------------------------------------
 # Maximum file size (kilobytes) IDE should provide code assistance for.
 # The larger file is the slower its editor works and higher overall system memory 
 requirements are
 # if code assistance is enabled. Remove this property or set to very large number 
 if you need
 # code assistance for any files available regardless their size.
 #---------------------------------------------------------------------
 idea.max.intellisense.filesize=2500

3. File -> Invalidate / Restart -> Restart

This might not update sometimes and you might need to edit the root idea.properties file.

To edit this file for any version of Idea

1. Go to application location i.e linux => /opt/PhpStorm[version]/bin
2. Find file called idea.properties Make backup of file i.e idea.properties.old
3. Open original with any txt editor.
4. Find idea.max.intellisense.filesize=
5. Replace with idea.max.intellisense.filesize=your_required_size i.e idea.max.intellisense.filesize=10480 NB by default this size is in kb
6. Save and restart the IDE.

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.

1-make a search in your local drive and type "php.ini" 2-you may see many files named php.ini you should choose the one that fits with your php version (see localhost) 3-open the php.ini file make a search on "max_execution_time" then make it equal to "-1" to make it unlimited

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.

Oracle will try to recompile invalid objects as they are referred to. Here the trigger is invalid, and every time you try to insert a row it will try to recompile the trigger, and fail, which leads to the ORA-04098 error.

You can select * from user_errors where type = 'TRIGGER' and name = 'NEWALERT' to see what error(s) the trigger actually gets and why it won't compile. In this case it appears you're missing a semicolon at the end of the insert line:

INSERT INTO Users (userID, firstName, lastName, password)
VALUES ('how', 'im', 'testing', 'this trigger')

So make it:

CREATE OR REPLACE TRIGGER newAlert
AFTER INSERT OR UPDATE ON Alerts
  BEGIN
        INSERT INTO Users (userID, firstName, lastName, password)
        VALUES ('how', 'im', 'testing', 'this trigger');
  END;           
/

If you get a compilation warning when you do that you can do show errors if you're in SQL*Plus or SQL Developer, or query user_errors again.

Of course, this assumes your Users tables does have those column names, and they are all varchar2... but presumably you'll be doing something more interesting with the trigger really.

Problem solved! I'm using Ctrl + Alt + E to open Exception Window, and I checked all throw checkbox. So the debuger can stop at the exactly the error code.

The answer with for is correct, but if you really want to use functional style avoiding for statement - you can use the following instead of your expression:

Array.from(Array(1000000), () => Math.random());

The Array.from() method creates a new Array instance from an array-like or iterable object. The second argument of this method is a map function to call on every element of the array.

Following the same idea you can rewrite it using ES2015 Spread operator:

[...Array(1000000)].map(() => Math.random())

In both examples you can get an index of the iteration if you need, for example:

[...Array(1000000)].map((_, i) => i + 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");

Try

df.loc[df.my_channel > 20000, 'my_channel'] = 0

Note: Since v0.20.0, ix has been deprecated in favour of loc / iloc.

As already explained in other answers, when in Private Browsing mode Safari will always throw this exception when trying to save data with localStorage.setItem() .

To fix this I wrote a fake localStorage that mimics localStorage, both methods and events.

Fake localStorage: https://gist.github.com/engelfrost/fd707819658f72b42f55

This is probably not a good general solution to the problem. This was a good solution for my scenario, where the alternative would be major re-writes to an already existing application.

My problem was that I could no longer run an emulator that had worked because I had quit the emulator application but the process wasn't fully ended, so I was trying to launch another emulator while the previous one was still running. On a mac, I had to use the Activity Monitor to see the other process and kill it. Steps:

1. Open Activity Monitor (in Utilities or using Command+Space)
2. Locate the process name, in my case, qemu-system...
3. Select the process.
4. Force the process to quit using the 'x' button in the top left.
5. I didn't have to use 'Force Quit', just the plain 'Quit', but you can use either.

You can use loop for.

var items = {1, 2, 3}
for(var i = 0; i < items.length; i++) {
  if(i == items.length - 1) {
    res.ok(i);
  }
}

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.

If you have Stress Test tool like JMeter you can test youself.

Well one way to do it is set the height of your body to the height that you want your page to be. In this example I did 600px.

Then set your wrapper height to a percentage of the body here I did 70% This will adjust your table so that it does not fill up the whole screen but in stead just takes up a percentage of the specified page height.

body {
   padding-top: 70px;
   border:1px solid black;
   height:600px;
}

.mygrid-wrapper-div {
   border: solid red 5px;
   overflow: scroll;
   height: 70%;
}

http://jsfiddle.net/4NB2N/7/

Update How about a jQuery approach.

$(function() {  
   var window_height = $(window).height(),
   content_height = window_height - 200;
   $('.mygrid-wrapper-div').height(content_height);
});

$( window ).resize(function() {
   var window_height = $(window).height(),
   content_height = window_height - 200;
   $('.mygrid-wrapper-div').height(content_height);
});

I had this issue when I didn't have a gitignore file with my iOS project

I think maybe it was trying to push a humungous file to github and github was probably rejecting that giant file or (files)

Mongoose and multiple database in single node.js project

use useDb to solve this issue

example

//product databse

const myDB = mongoose.connection.useDb('product');

module.exports = myDB.model("Snack", snackSchema);

//user databse

const myDB = mongoose.connection.useDb('user');

module.exports = myDB.model("User", userSchema);

The link below will demonstrate how I accomplished this. Not very hard - just have to use some clever front-end dev!!

.selected-elementClass{

You could use a div with a background image instead and this CSS3 property:

background-size: contain

You can check out an example on:

https://developer.mozilla.org/en-US/docs/Web/Guide/CSS/Scaling_background_images#contain

To quote Mozilla:

The contain value specifies that regardless of the size of the containing box, the background image should be scaled so that each side is as large as possible while not exceeding the length of the corresponding side of the container.

However, keep in mind that your image will be upscaled if the div is larger than your original image.

Try something like this:

.popup__overlay {
    position: fixed;

Make sure u close all instances wcfSvcHost and try again. It worked for me!

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

You also have an error in your css with the exclamation point in this line:

background:rgb(242, 242, 242);!important;

remove the semi-colon before it. However, !important should be used rarely and can largely be avoided.

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 fadeIn() function calls the fadeOut() function, which calls the fadeIn() function again. the recursion is in the JS.

Assuming that you are using a spfile to start the database

alter system set open_cursors = 1000 scope=both;

If you are using a pfile instead, you can change the setting for the running instance

alter system set open_cursors = 1000 

You would also then need to edit the parameter file to specify the new open_cursors setting. It would generally be a good idea to restart the database shortly thereafter to make sure that the parameter file change works as expected (it's highly annoying to discover months later the next time that you reboot the database that some parameter file change than no one remembers wasn't done correctly).

I'm also hoping that you are certain that you actually need more than 300 open cursors per session. A large fraction of the time, people that are adjusting this setting actually have a cursor leak and they are simply trying to paper over the bug rather than addressing the root cause.

A little late but someone can use this in future...You can increase your test timeout by updating scripts in your package.json with the following:

"scripts": { "test": "test --timeout 10000" //Adjust to a value you need }

Run your tests using the command test

I'd like to propose

np.min(np.append(np.where(aa>5)[0],np.inf))

This will return the smallest index where the condition is met, while returning infinity if the condition is never met (and where returns an empty array).

Please see my class that is a scrollable frame. It's vertical scrollbar is binded to <Mousewheel> event as well. So, all you have to do is to create a frame, fill it with widgets the way you like, and then make this frame a child of my ScrolledWindow.scrollwindow. Feel free to ask if something is unclear.

Google Maps actually uses signed values to represent the position:

• Latitude : max/min 90.0000000 to -90.0000000

• Longitude : max/min 180.0000000 to -180.0000000

So if you want to work with Coordinates in your projects you would need DECIMAL(10,7) ie. for SQL.

As pointed already by @Arun P Johny the root cause of the problem is that at the moment when AuthenticationSuccessEvent is processed SecurityContextHolder is not populated by Authentication object. So any declarative authorization checks (that must get user rights from SecurityContextHolder) will not work. I give you another idea how to solve this problem. There are two ways how you can run your custom code immidiately after successful authentication:

1. Listen to AuthenticationSuccessEvent
2. Provide your custom AuthenticationSuccessHandler implementation.

AuthenticationSuccessHandler has one important advantage over first way: SecurityContextHolder will be already populated. So just move your stateService.rowCount() call into loginsuccesshandler.LoginSuccessHandler#onAuthenticationSuccess(...) method and the problem will go away.

It is the underlying urllib3 library that does the retrying. To set a different maximum retry count, use alternative transport adapters:

from requests.adapters import HTTPAdapter

s = requests.Session()
s.mount('http://stackoverflow.com', HTTPAdapter(max_retries=5))

The max_retries argument takes an integer or a Retry() object; the latter gives you fine-grained control over what kinds of failures are retried (an integer value is turned into a Retry() instance which only handles connection failures; errors after a connection is made are by default not handled as these could lead to side-effects).

Old answer, predating the release of requests 1.2.1:

The requests library doesn't really make this configurable, nor does it intend to (see this pull request). Currently (requests 1.1), the retries count is set to 0. If you really want to set it to a higher value, you'll have to set this globally:

import requests

requests.adapters.DEFAULT_RETRIES = 5

This constant is not documented; use it at your own peril as future releases could change how this is handled.

Update: and this did change; in version 1.2.1 the option to set the max_retries parameter on the HTTPAdapter() class was added, so that now you have to use alternative transport adapters, see above. The monkey-patch approach no longer works, unless you also patch the HTTPAdapter.__init__() defaults (very much not recommended).

If you are using Bootstrap 3 and Less you could apply the responsive tables to all resolutions by updatingthe file:

tables.less

or overwriting this part:

@media (max-width: @screen-xs) {
  .table-responsive {
    width: 100%;
    margin-bottom: 15px;
    overflow-y: hidden;
    overflow-x: scroll;
    border: 1px solid @table-border-color;

    // Tighten up spacing and give a background color
    > .table {
      margin-bottom: 0;
      background-color: #fff;

      // Ensure the content doesn't wrap
      > thead,
      > tbody,
      > tfoot {
        > tr {
          > th,
          > td {
            white-space: nowrap;
          }
        }
      }
    }

    // Special overrides for the bordered tables
    > .table-bordered {
      border: 0;

      // Nuke the appropriate borders so that the parent can handle them
      > thead,
      > tbody,
      > tfoot {
        > tr {
          > th:first-child,
          > td:first-child {
            border-left: 0;
          }
          > th:last-child,
          > td:last-child {
            border-right: 0;
          }
        }
        > tr:last-child {
          > th,
          > td {
            border-bottom: 0;
          }
        }
      }
    }
  }
}

With:

@media (max-width: @screen-lg) {
  .table-responsive {
    width: 100%;
...

Note how I changed the first line @screen-XX value.

I know making all tables responsive may not sound that good, but I found it extremely useful to have this enabled up to LG on large tables (lots of columns).

Hope it helps someone.

Having had this exception myself, I delved into the JRE source code. It became apparent that the message is rather misleading. It could mean what it says, but it more generally means that the server doesn't have the data it needs to respond to the client in the requested way. This can happen, for example, if certificates are missing from the keystore, or haven't been generated with the an appropriate algoritm. Indeed, given the cipher suites that are installed by default, one would have to go to some lengths to really get this exception because of lack of common cipher suites. In my particular case I'd generated the certificates with the default algorithm of DSA, when what I needed to get the server to work with Firefox was RSA.

This work for me

Demo: jsfiddle

$(function() 
{
    Fixed_Header();
});

function Fixed_Header()
{
    $('.User_Table thead').css({'position': 'absolute'});
    $('.User_Table tbody tr:eq("2") td').each(function(index,e){
        $('.User_Table thead tr th:eq("'+index+'")').css({'width' : $(this).outerWidth() +"px" });
    });
    var Header_Height = $('.User_Table thead').outerHeight();
    $('.User_Table thead').css({'margin-top' : "-"+Header_Height+"px"});
    $('.User_Table').css({'margin-top' : Header_Height+"px"});
}

When you get the width and height of a resized image Get width of a resized image after UIViewContentModeScaleAspectFit, you can resize your imageView:

imageView.frame = CGRectMake(0, 0, resizedWidth, resizedHeight);
imageView.center = imageView.superview.center;

I haven't checked if it works, but I think all should be OK

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

Change the customBinding in the web.config to use larger defaults. I picked 2MB as it is a reasonable size. Of course setting it to 2GB (as your code suggests) will work but it does leave you more vulnerable to attacks. Pick a size that is larger than your largest request but isn't overly large.

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.

ORA-01000, the maximum-open-cursors error, is an extremely common error in Oracle database development. In the context of Java, it happens when the application attempts to open more ResultSets than there are configured cursors on a database instance.

Common causes are:

1. Configuration mistake

   • You have more threads in your application querying the database than cursors on the DB. One case is where you have a connection and thread pool larger than the number of cursors on the database.
   • You have many developers or applications connected to the same DB instance (which will probably include many schemas) and together you are using too many connections.

   • Solution:

     • Increasing the number of cursors on the database (if resources allow) or
     • Decreasing the number of threads in the application.

2. Cursor leak

   • The applications is not closing ResultSets (in JDBC) or cursors (in stored procedures on the database)
   • Solution: Cursor leaks are bugs; increasing the number of cursors on the DB simply delays the inevitable failure. Leaks can be found using static code analysis, JDBC or application-level logging, and database monitoring.

Background

This section describes some of the theory behind cursors and how JDBC should be used. If you don't need to know the background, you can skip this and go straight to 'Eliminating Leaks'.

What is a cursor?

A cursor is a resource on the database that holds the state of a query, specifically the position where a reader is in a ResultSet. Each SELECT statement has a cursor, and PL/SQL stored procedures can open and use as many cursors as they require. You can find out more about cursors on Orafaq.

A database instance typically serves several different schemas, many different users each with multiple sessions. To do this, it has a fixed number of cursors available for all schemas, users and sessions. When all cursors are open (in use) and request comes in that requires a new cursor, the request fails with an ORA-010000 error.

Finding and setting the number of cursors

The number is normally configured by the DBA on installation. The number of cursors currently in use, the maximum number and the configuration can be accessed in the Administrator functions in Oracle SQL Developer. From SQL it can be set with:

ALTER SYSTEM SET OPEN_CURSORS=1337 SID='*' SCOPE=BOTH;

Relating JDBC in the JVM to cursors on the DB

The JDBC objects below are tightly coupled to the following database concepts:

• JDBC Connection is the client representation of a database session and provides database transactions. A connection can have only a single transaction open at any one time (but transactions can be nested)
• A JDBC ResultSet is supported by a single cursor on the database. When close() is called on the ResultSet, the cursor is released.
• A JDBC CallableStatement invokes a stored procedure on the database, often written in PL/SQL. The stored procedure can create zero or more cursors, and can return a cursor as a JDBC ResultSet.

JDBC is thread safe: It is quite OK to pass the various JDBC objects between threads.

For example, you can create the connection in one thread; another thread can use this connection to create a PreparedStatement and a third thread can process the result set. The single major restriction is that you cannot have more than one ResultSet open on a single PreparedStatement at any time. See Does Oracle DB support multiple (parallel) operations per connection?

Note that a database commit occurs on a Connection, and so all DML (INSERT, UPDATE and DELETE's) on that connection will commit together. Therefore, if you want to support multiple transactions at the same time, you must have at least one Connection for each concurrent Transaction.

Closing JDBC objects

A typical example of executing a ResultSet is:

Statement stmt = conn.createStatement();
try {
    ResultSet rs = stmt.executeQuery( "SELECT FULL_NAME FROM EMP" );
    try {
        while ( rs.next() ) {
            System.out.println( "Name: " + rs.getString("FULL_NAME") );
        }
    } finally {
        try { rs.close(); } catch (Exception ignore) { }
    }
} finally {
    try { stmt.close(); } catch (Exception ignore) { }
}

Note how the finally clause ignores any exception raised by the close():

• If you simply close the ResultSet without the try {} catch {}, it might fail and prevent the Statement being closed
• We want to allow any exception raised in the body of the try to propagate to the caller. If you have a loop over, for example, creating and executing Statements, remember to close each Statement within the loop.

In Java 7, Oracle has introduced the AutoCloseable interface which replaces most of the Java 6 boilerplate with some nice syntactic sugar.

Holding JDBC objects

JDBC objects can be safely held in local variables, object instance and class members. It is generally better practice to:

• Use object instance or class members to hold JDBC objects that are reused multiple times over a longer period, such as Connections and PreparedStatements
• Use local variables for ResultSets since these are obtained, looped over and then closed typically within the scope of a single function.

There is, however, one exception: If you are using EJBs, or a Servlet/JSP container, you have to follow a strict threading model:

• Only the Application Server creates threads (with which it handles incoming requests)
• Only the Application Server creates connections (which you obtain from the connection pool)
• When saving values (state) between calls, you have to be very careful. Never store values in your own caches or static members - this is not safe across clusters and other weird conditions, and the Application Server may do terrible things to your data. Instead use stateful beans or a database.
• In particular, never hold JDBC objects (Connections, ResultSets, PreparedStatements, etc) over different remote invocations - let the Application Server manage this. The Application Server not only provides a connection pool, it also caches your PreparedStatements.

Eliminating leaks

There are a number of processes and tools available for helping detect and eliminating JDBC leaks:

1. During development - catching bugs early is by far the best approach:

   1. Development practices: Good development practices should reduce the number of bugs in your software before it leaves the developer's desk. Specific practices include:

      1. Pair programming, to educate those without sufficient experience
      2. Code reviews because many eyes are better than one
      3. Unit testing which means you can exercise any and all of your code base from a test tool which makes reproducing leaks trivial
      4. Use existing libraries for connection pooling rather than building your own

   2. Static Code Analysis: Use a tool like the excellent Findbugs to perform a static code analysis. This picks up many places where the close() has not been correctly handled. Findbugs has a plugin for Eclipse, but it also runs standalone for one-offs, has integrations into Jenkins CI and other build tools

2. At runtime:

   1. Holdability and commit

      1. If the ResultSet holdability is ResultSet.CLOSE_CURSORS_OVER_COMMIT, then the ResultSet is closed when the Connection.commit() method is called. This can be set using Connection.setHoldability() or by using the overloaded Connection.createStatement() method.

   2. Logging at runtime.

      1. Put good log statements in your code. These should be clear and understandable so the customer, support staff and teammates can understand without training. They should be terse and include printing the state/internal values of key variables and attributes so that you can trace processing logic. Good logging is fundamental to debugging applications, especially those that have been deployed.

      2. You can add a debugging JDBC driver to your project (for debugging - don't actually deploy it). One example (I have not used it) is log4jdbc. You then need to do some simple analysis on this file to see which executes don't have a corresponding close. Counting the open and closes should highlight if there is a potential problem

         3. Monitoring the database. Monitor your running application using the tools such as the SQL Developer 'Monitor SQL' function or Quest's TOAD. Monitoring is described in this article. During monitoring, you query the open cursors (eg from table v$sesstat) and review their SQL. If the number of cursors is increasing, and (most importantly) becoming dominated by one identical SQL statement, you know you have a leak with that SQL. Search your code and review.

Can you use WeakReferences to handle closing connections?

Weak and soft references are ways of allowing you to reference an object in a way that allows the JVM to garbage collect the referent at any time it deems fit (assuming there are no strong reference chains to that object).

If you pass a ReferenceQueue in the constructor to the soft or weak Reference, the object is placed in the ReferenceQueue when the object is GC'ed when it occurs (if it occurs at all). With this approach, you can interact with the object's finalization and you could close or finalize the object at that moment.

Phantom references are a bit weirder; their purpose is only to control finalization, but you can never get a reference to the original object, so it's going to be hard to call the close() method on it.

However, it is rarely a good idea to attempt to control when the GC is run (Weak, Soft and PhantomReferences let you know after the fact that the object is enqueued for GC). In fact, if the amount of memory in the JVM is large (eg -Xmx2000m) you might never GC the object, and you will still experience the ORA-01000. If the JVM memory is small relative to your program's requirements, you may find that the ResultSet and PreparedStatement objects are GCed immediately after creation (before you can read from them), which will likely fail your program.

TL;DR: The weak reference mechanism is not a good way to manage and close Statement and ResultSet objects.

I usually use set_time_limit(30) within the main loop (so each loop iteration is limited to 30 seconds rather than the whole script).

I do this in multiple database update scripts, which routinely take several minutes to complete but less than a second for each iteration - keeping the 30 second limit means the script won't get stuck in an infinite loop if I am stupid enough to create one.

I must admit that my choice of 30 seconds for the limit is somewhat arbitrary - my scripts could actually get away with 2 seconds instead, but I feel more comfortable with 30 seconds given the actual application - of course you could use whatever value you feel is suitable.

Hope this helps!

It is important to understand that the transaction buffer is limited to 1 MB, regardless of device capabilities or app. This buffer is used with every API calls you make and is shared amongst all transactions an app is currently running.

I believe it also holds some specific object like parcels and such (Parcel.obtain()), so it's important to always match every obtain() with a recycle().

This error can easily happen on API calls returning a lot of data, even though the returned data is less than 1 MB (if other transactions are still running).

For example, the PackageManager.getInstalledApplication() call returns a list of all apps installed. Adding specific flags allows to retrieve a lot of extra data. Doing so is likely to fail, so it's recommended not to retrieve any extra data and retrieve those on a per-app basis.

However the call may still fail, so it's important to surround it with a catch and be able to retry if necessary.

As far as I know, there's no work-around to such issue except retrying and making sure to retrieve as little information as possible.

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

Excel shows 24:03 as 3 minutes when you format it as time, because 24:03 is the same as 12:03 AM (in military time).

Use General Format to Add Times

Instead of trying to format as Time, use the General Format and the following formula:

=number of minutes + (number of seconds / 60)

Ex: for 24 minutes and 3 seconds:

=24+3/60

This will give you a value of 24.05.

Do this for each time period. Let's say you enter this formula in cells A1 and A2. Then, to get the total sum of elapsed time, use this formula in cell A3:

=INT(A1+A2)+MOD(A1+A2,1)

Convert back to minutes and seconds

If you put =24+3/60 into each cell, you will have a value of 48.1 in cell A3.

Now you need to convert this back to minutes and seconds. Use the following formula in cell A4:

=MOD(A3,1)*60

This takes the decimal portion and multiples it by 60. Remember, we divided by 60 in the beginning, so to convert it back to seconds we need to multiply.

You could have also done this separately, i.e. in cell A3 use this formula:

=INT(A1+A2)

and this formula in cell A4:

=MOD(A1+A2,1)*60

Here's a screenshot showing the final formulas:

Pandas offer a great way to manipulate tables, as you can make binning easy (binning a dataframe in pandas in Python) and calculate statistics. Other thing that is great in pandas is the Panel class that you can join series of layers with different properties and combine it using groupby function.

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" />

I know an answer has already been accepted for this problem but someone asked in the comments if there was a solution that could be done outside the web.config. I had a ListView producing the exact same error and setting EnableViewState to false resolved this problem for me.

You can use the Interval class from Eclipse Collections.

List<Integer> range = Interval.oneTo(10);
range.forEach(System.out::print);  // prints 12345678910

The Interval class is lazy, so doesn't store all of the values.

LazyIterable<Integer> range = Interval.oneTo(10);
System.out.println(range.makeString(",")); // prints 1,2,3,4,5,6,7,8,9,10

Your method would be able to be implemented as follows:

public List<Integer> makeSequence(int begin, int end) {
    return Interval.fromTo(begin, end);
}

If you would like to avoid boxing ints as Integers, but would still like a list structure as a result, then you can use IntList with IntInterval from Eclipse Collections.

public IntList makeSequence(int begin, int end) {
    return IntInterval.fromTo(begin, end);
}

IntList has the methods sum(), min(), minIfEmpty(), max(), maxIfEmpty(), average() and median() available on the interface.

Update for clarity: 11/27/2017

An Interval is a List<Integer>, but it is lazy and immutable. It is extremely useful for generating test data, especially if you deal a lot with collections. If you want you can easily copy an interval to a List, Set or Bag as follows:

Interval integers = Interval.oneTo(10);
Set<Integer> set = integers.toSet();
List<Integer> list = integers.toList();
Bag<Integer> bag = integers.toBag();

An IntInterval is an ImmutableIntList which extends IntList. It also has converter methods.

IntInterval ints = IntInterval.oneTo(10);
IntSet set = ints.toSet();
IntList list = ints.toList();
IntBag bag = ints.toBag();

An Interval and an IntInterval do not have the same equals contract.

Update for Eclipse Collections 9.0

You can now create primitive collections from primitive streams. There are withAll and ofAll methods depending on your preference. If you are curious, I explain why we have both here. These methods exist for mutable and immutable Int/Long/Double Lists, Sets, Bags and Stacks.

Assert.assertEquals(
        IntInterval.oneTo(10),
        IntLists.mutable.withAll(IntStream.rangeClosed(1, 10)));

Assert.assertEquals(
        IntInterval.oneTo(10),
        IntLists.immutable.withAll(IntStream.rangeClosed(1, 10)));

Updating the ulimit worked for my Kosaraju's SCC implementation by fixing the segfault on both Python (Python segfault.. who knew!) and C++ implementations.

For my MAC, I found out the possible maximum via :

$ ulimit -s -H
65532

You could add the following VBA code to your sheet:

Private Sub Worksheet_Change(ByVal Target As Range)
    If Range("A1") > 0.5 Then
        MsgBox "Discount too high"
    End If
End Sub

Every time a cell is changed on the sheet, it will check the value of cell A1.

Notes:

• if A1 also depends on data located in other spreadsheets, the macro will not be called if you change that data.
• the macro will be called will be called every time something changes on your sheet. If it has lots of formula (as in 1000s) it could be slow.

Widor uses a different approach (Worksheet_Calculate instead of Worksheet_Change):

• Pros: his method will work if A1's value is linked to cells located in other sheets.
• Cons: if you have many links on your sheet that reference other sheets, his method will run a bit slower.

Conclusion: use Worksheet_Change if A1 only depends on data located on the same sheet, use Worksheet_Calculate if not.

in my case the issue was in the EOL Conversion. (End Of Line).

i created the file on windows and only after i converted the EOL from windows(CR LF) to unix(LF), everything went well.

I did the conversion with Notepad++ very easily from: Edit -> EOL Conversion -> Unix(LF)

Length of characters to be matched.

{n,m}  n <= length <= m
{n}    length == n
{n,}   length >= n

And by default, the engine is greedy to match this pattern. For example, if the input is 123456789, \d{2,5} will match 12345 which is with length 5.

If you want the engine returns when length of 2 matched, use \d{2,5}?

For ASP.NET 1.1, this is still due to someone posting more than 1000 form fields, but the setting must be changed in the registry rather than a config file. It should be added as a DWORD named MaxHttpCollectionKeys in the registry under

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\ASP.NET\1.1.4322.0

for 32-bit editions of Windows, and

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\ASP.NET\1.1.4322.0

for 64-bit editions of Windows.

This can be caused by the two sides of the connection disagreeing over whether the connection timed out or not during a keepalive. (Your code tries to reused the connection just as the server is closing it because it has been idle for too long.) You should basically just retry the operation over a new connection. (I'm surprised your library doesn't do this automatically.)

You can try adding:

#aboutDescription
{
    height: 100px;
    max-height: 100px;  
}

With Kotlin it is as simple as:

yourString.take(10)

Returns a string containing the first n characters from this string, or the entire string if this string is shorter.

Documentation

For readability, I prefer this:

if (inputString.length() > maxLength) {
    inputString = inputString.substring(0, maxLength);
}

over the accepted answer.

int maxLength = (inputString.length() < MAX_CHAR)?inputString.length():MAX_CHAR;
inputString = inputString.substring(0, maxLength);

Although adding something to nodejs module is possible, it seems to be not the best way (if you try to run your code on other computer, the program will crash with the same error, obviously).

I would rather set max listeners number in your own code:

var options = {uri:headingUri, headers:headerData, maxRedirects:100};
request.setMaxListeners(0);
request.get(options, function (error, response, body) {
}

It's been a while, but last time I had something similar:

ROLLBACK TRAN

or trying to

COMMIT

what had allready been done free'd everything up so I was able to clear things out and start again.

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.

Change your || to && so it will only exit if the answer is NEITHER "AM" nor "PM".

Xampp Users

1. Go to xampp\phpMyAdmin\
2. Open config.inc.php
3. Search for $cfg['ExecTimeLimit'] = 300;
4. Set a larger value or change to 0 for unlimited
5. If not found add $cfg['ExecTimeLimit'] = 0; (or a larger value)
6. Save the file and restart the server

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.’)

You can also get this error when you have an infinite loop. Make sure that you don't have any unending, recursive self references.

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*/

In my case, I work with MySQL Workbench (5.6.17) running on Windows with WampServer 2.5.

For Windows/WampServer you have to edit the my.ini file (not the my.cnf file)

To locate this file go to Menu Server/Server Status (in MySQL Workbench) and look under Server Directories/ Base Directory

In my.ini file there are defined sections for different settings, look for section [mysqld] (create it if it does not exist) and add the command: innodb_buffer_pool_size=4G

[mysqld]
innodb_buffer_pool_size=4G

The size of the buffer_pool file will depend on your specific machine, in most cases, 2G or 4G will fix the problem.

Remember to restart the server so it takes the new configuration, it corrected the problem for me.

Hope it helps!

Instead of doing recursion, the parts of the code with checkNextID(ID + 18) and similar could be replaced with ID+=18, and then if you remove all instances of return 0, then it should do the same thing but as a simple loop. You should then put a return 0 at the end and make your variables non-global.

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;
}

I haven't had any problems with the code below. (Relative paths must start with '/' or '\').

private bool IsValidPath(string path, bool allowRelativePaths = false)
{
    bool isValid = true;

    try
    {
        string fullPath = Path.GetFullPath(path);

        if (allowRelativePaths)
        {
            isValid = Path.IsPathRooted(path);
        }
        else
        {
            string root = Path.GetPathRoot(path);
            isValid = string.IsNullOrEmpty(root.Trim(new char[] { '\\', '/' })) == false;
        }
    }
    catch(Exception ex)
    {
        isValid = false;
    }

    return isValid;
}

For example these would return false:

IsValidPath("C:/abc*d");
IsValidPath("C:/abc?d");
IsValidPath("C:/abc\"d");
IsValidPath("C:/abc<d");
IsValidPath("C:/abc>d");
IsValidPath("C:/abc|d");
IsValidPath("C:/abc:d");
IsValidPath("");
IsValidPath("./abc");
IsValidPath("./abc", true);
IsValidPath("/abc");
IsValidPath("abc");
IsValidPath("abc", true);

And these would return true:

IsValidPath(@"C:\\abc");
IsValidPath(@"F:\FILES\");
IsValidPath(@"C:\\abc.docx\\defg.docx");
IsValidPath(@"C:/abc/defg");
IsValidPath(@"C:\\\//\/\\/\\\/abc/\/\/\/\///\\\//\defg");

I had the same problem.please do the following it may help you: By Default List View Threshold set at only 5,000 items this is because of Sharepoint server performance.

To Change the LVT:

1. Click SharePoint Central Administration,
2. Go to Application Management
3. Manage Web Applications
4. Select your application
5. Click General Settings at the ribbon
6. Select Resource Throttling
7. List View Threshold limit --> change the value to your need.
8. Also change the List View Threshold for Auditors and Administrators.if you are a administrator.

Click OK to save it.

You can use:

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.

If your app use multiple webview you will still have troubles : localStorage is not correctly shared accross all webviews.

If you want to share the same data in multiple webviews the only way is to repair it with a java database and a javascript interface.

This page on github shows how to do this.

hope this help!

Don't store the whole structure in memory while waiting to get to the end.

Write intermediate results to a temporary table in the database instead of hashmaps - functionally, a database table is the equivalent of a hashmap, i.e. both support keyed access to data, but the table is not memory bound, so use an indexed table here rather than the hashmaps.

If done correctly, your algorithm should not even notice the change - correctly here means to use a class to represent the table, even giving it a put(key, value) and a get(key) method just like a hashmap.

When the intermediate table is complete, generate the required sql statement(s) from it instead of from memory.

This kind of thing happened to me when I was using php language construct exit; in middle of transaction. Then this transaction "hangs" and you need to kill mysql process (described above with processlist;)

For standard OS X installations of MySQL you will find my.cnf located in the /etc/ folder.

Steps to update this variable:

1. Load Terminal.
2. Type cd /etc/.
3. sudo vi my.cnf.
4. This file should already exist (if not please use sudo find / -name 'my.cnf' 2>1 - this will hide the errors and only report the successfile file location).
5. Using vi(m) find the line innodb_buffer_pool_size, press i to start making changes.
6. When finished, press esc, shift+colon and type wq.

Unfortunately the web.config setting is ignored by the default JsonResult implementation. So I guess you will need to implement a custom json result to overcome this issue.

You need to use LogLevel rewrite:trace3 to your httpd.conf in newer version http://httpd.apache.org/docs/2.4/mod/mod_rewrite.html#logging

For me, the settings in web.config / app.config were ignored. I ended up creating my binding manually, which solved the issue for me:

var httpBinding = new BasicHttpBinding()
{
    MaxBufferPoolSize = Int32.MaxValue,
    MaxBufferSize = Int32.MaxValue,
    MaxReceivedMessageSize = Int32.MaxValue,
    ReaderQuotas = new XmlDictionaryReaderQuotas()
    {
        MaxArrayLength = 200000000,
        MaxDepth = 32,
        MaxStringContentLength = 200000000
    }
};

I haven't tried the discussed things myself, but the bigmemory package seems very useful

I had the same problem and solved it by changing the value for the param max_execution_time in php.ini, like this:

max_execution_time = 360      ; Maximum execution time of each script, in seconds (I CHANGED THIS VALUE)
max_input_time = 120          ; Maximum amount of time each script may spend parsing request data
;max_input_nesting_level = 64 ; Maximum input variable nesting level
memory_limit = 128M           ; Maximum amount of memory a script may consume (128MB by default)

I hope this could help you.

Thank you so much! <%Response.Buffer = False%> worked like a charm! My asp/HTML table that was returning a blank page at about 2700 records. The following debugging lines helped expose the buffering problem: I replace the Do While loop as follows and played with my limit numbers to see what was happening:

Replace

Do While not rs.EOF

'etc .... your block of code that writes the table rows

rs.moveNext

Loop

with

Do While reccount < 2500

if rs.EOF then recount = 2501

'etc .... your block of code that writes the table rows

rs.moveNext

Loop

response.write "recount = " & recount

raise or lower the 2500 and 2501 to see if it is a buffer problem. for my record set, I could see that the blank page return, blank table, was happening at about 2700 records, good luck to all and thank you again for solving this problem! Such a simple great solution!

For the case where the TextView is inside a TableLayout, the solution is to set android:shrinkColumns="1" on the TableLayout. (Replace 1 with the column number the TextView you want to wrap is in. (0-indexed))

AFAICT, no other attributes are needed on the TextView.

For other cases, see the other answers here.

FWIW, I had initially gotten it to sort of work with

 <TextView
   android:id="@+id/inventory_text"
   android:layout_width="fill_parent"
   android:layout_weight="1"
   android:width="0dp"

but that resulted in some extra empty space at the bottom of the Dialog it was all in.

To post a clarification answer here for those who get directed here by Google.

The document size includes everything in the document including the subdocuments, nested objects etc.

So a document of:

{
  "_id": {},
  "na": [1, 2, 3],
  "naa": [
    { "w": 1, "v": 2, "b": [1, 2, 3] },
    { "w": 5, "b": 2, "h": [{ "d": 5, "g": 7 }, {}] }
  ]
}

Has a maximum size of 16 MB.

Subdocuments and nested objects are all counted towards the size of the document.

First, you will have to store the value in a variable like this

$value = explode("/", $string);

Then you can use the end function to get the last index from an array like this

echo end($value);

I hope it will work for you.

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.

Another method: insert the following in your theme's function.php file.

remove_filter('get_the_excerpt', 'wp_trim_excerpt');
add_filter('get_the_excerpt', 'custom_trim_excerpt');

function custom_trim_excerpt($text) { // Fakes an excerpt if needed
global $post;
if ( '' == $text ) {
$text = get_the_content('');
$text = apply_filters('the_content', $text);
$text = str_replace(']]>', ']]>', $text);
$text = strip_tags($text);
$excerpt_length = x;
$words = explode(' ', $text, $excerpt_length + 1);
if (count($words) > $excerpt_length) {
array_pop($words);
array_push($words, '...');
$text = implode(' ', $words);
}
}
return $text;
}

You can use this.

In general, you can use a backslash at the end of a line in order for the command to continue on to the next line. However, there are cases where commands are implicitly continued, namely when the line ends with a token than cannot legally terminate a command. In that case, the shell knows that more is coming, and the backslash can be omitted. Some examples:

# In general
$ echo "foo" \
> "bar"
foo bar

# Pipes
$ echo foo |
> cat
foo

# && and ||
$ echo foo &&
> echo bar
foo
bar
$ false ||
> echo bar
bar

Different, but related, is the implicit continuation inside quotes. In this case, without a backslash, you are simply adding a newline to the string.

$ x="foo
> bar"
$ echo "$x"
foo
bar

With a backslash, you are again splitting the logical line into multiple logical lines.

$ x="foo\
> bar"
$ echo "$x"
foobar

It bothered me for days too. I modified the Web.config file but it didn't work. It turned out that there are two Web.config file in my project, and I should modified the one in the ROOT directory, not the others. Hope this would be helpful.

You need to change some setting in your php.ini:

upload_max_filesize = 2M 
;or whatever size you want

max_execution_time = 60
; also, higher if you must - sets the maximum time in seconds

Were your PHP.ini is located depends on your environment, more information: http://php.net/manual/en/ini.list.php

Try this one, should work:

cast((convert(bigint,b.tax_id)) as varchar(20))

The file format would permit up to 255-character worksheet names, but if the Excel UI doesn't want you exceeding 31 characters, don't try to go beyond 31. App's full of weird undocumented limits and quirks, and feeding it files that are within spec but not within the range of things the testers would have tested usually causes REALLY strange behavior. (Personal favorite example: using the Excel 4.0 bytecode for an if() function, in a file with an Excel 97-style stringtable, disabled the toolbar button for bold in Excel 97.)

You can try this one

img{
    max-height:500px;
    max-width:500px;
    height:auto;
    width:auto;
}

This keeps the aspect ratio of the image and prevents either the two dimensions exceed 500px

You can check this 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 :

http://vdachev.net/2007/02/22/mysql-reducing-ibdata1/

You can use the window.innerHeight

No. I'd love for someone to correct me, but I accepted the load/resize approach you tried as a compromise.

Here are the steps for anyone browsing:

1. Calculate the maximum possible inSampleSize that still yields an image larger than your target.
2. Load the image using BitmapFactory.decodeFile(file, options), passing inSampleSize as an option.
3. Resize to the desired dimensions using Bitmap.createScaledBitmap().

Use generators?

def fib():
    a, b = 0, 1
    while True:
        yield a
        a, b = b, a + b

fibs = fib() #seems to be the only way to get the following line to work is to
             #assign the infinite generator to a variable

f = [fibs.next() for x in xrange(1001)]

for num in f:
        print num

above fib() function adapted from: http://intermediatepythonista.com/python-generators

I prefer jpierson's answer, but none of the examples here that I can see are handling an invalid maxLength parameter, such as when maxLength < 0.

Choices would be either handle the error in a try/catch, clamp the maxLength parameter min to 0, or if maxLength is less than 0 return an empty string.

Not optimized code:

public string Truncate(this string value, int maximumLength)
{
    if (string.IsNullOrEmpty(value) == true) { return value; }
    if (maximumLen < 0) { return String.Empty; }
    if (value.Length > maximumLength) { return value.Substring(0, maximumLength); }
    return value;
}

I had this problem when trying to delete a certain group of records (using MS Access 2007 with an ODBC connection to MySQL on a web server). Typically I would delete certain records from MySQL then replace with updated records (cascade delete several related records, this streamlines deleting all related records for a single record deletion).

I tried to run through the operations available in phpMyAdmin for the table (optimize,flush, etc), but I was getting a need permission to RELOAD error when I tried to flush. Since my database is on a web server, I couldn't restart the database. Restoring from a backup was not an option.

I tried running delete query for this group of records on the cPanel mySQL access on the web. Got same error message.

My solution: I used Sun's (Oracle's) free MySQL Query Browser (that I previously installed on my computer) and ran the delete query there. It worked right away, Problem solved. I was then able to once again perform the function using the Access script using the ODBC Access to MySQL connection.

That doesn't work because, judging by the rest of the code, the initial value of the text input is "Default text" - which is more than one character, and so your if condition is always true.

The simplest way to make it work, it seems to me, is to account for this case:

    var value = $(this).val();
    if ( value.length > 0 && value != "Default text" ) ...

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.

This seems to be the result you see from Firefox when the server is not configured properly for SSL. Chrome, BTW, just gave a generic "ssl failed" code.

What happens is that the browser sends a SSL handshake when the server is expecting an HTTP request. Server responds with a 400 code and an error message that is much bigger that the handshake message that the browser expects. Hence the FF message.

As we can see from the responses here there are many things that can break the SSL configuration but not stop the server starting or give any hints in error.log.

What I did was systematically check down all the answers until I finally found the right one, right at the bottom.

Here is what I had in the access logs:

rfulton.actrix.co.nz:80 192.168.1.3 - - [09/Oct/2016:13:39:32 +1300] "\x16\x03\x01" 400 0 "-" "-"
rfulton.actrix.co.nz:80 192.168.1.3 - - [09/Oct/2016:13:39:46 +1300] "\x16\x03\x01" 400 0 "-" "-"
rfulton.actrix.co.nz:80 192.168.1.3 - - [09/Oct/2016:13:49:13 +1300] "\x16\x03\x01" 400 0 "-" "-"

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 had the same problem and i created a .user.ini file and put it in the directory in which the upload script was located. Than inside that file i set these these two values:

  upload_max_filesize = 40M

  post_max_size = 40M

and it worked great for me!

The BitmapFactory.decode* methods, discussed in the Load Large Bitmaps Efficiently lesson, should not be executed on the main UI thread if the source data is read from disk or a network location (or really any source other than memory). The time this data takes to load is unpredictable and depends on a variety of factors (speed of reading from disk or network, size of image, power of CPU, etc.). If one of these tasks blocks the UI thread, the system flags your application as non-responsive and the user has the option of closing it (see Designing for Responsiveness for more information).

C# doesn't have an explicit line break character. You statements end with a semicolon so you can span your statements over many lines. These are both the same:

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

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

You may use PopupController for the same one the SDK which shows UIViewController as subview You may check PopupController

Here is sample code for the same

popup = PopupController
        .create(self.navigationController!)
        .customize(
            [
                .layout(.center),
                .animation(.fadeIn),
                .backgroundStyle(.blackFilter(alpha: 0.8)),
                .dismissWhenTaps(true),
                .scrollable(true)
            ]
        )
        .didShowHandler { popup in
        }
        .didCloseHandler { popup in
    }
    let container = MTMPlayerAndCardSelectionVC.instance()
    container.closeHandler = {() in
        self.popup.dismiss()
    }

    popup.show(container)

It's usually the code. Here's a simple example:

import java.util.*;

public class GarbageCollector {

    public static void main(String... args) {

        System.out.printf("Testing...%n");
        List<Double> list = new ArrayList<Double>();
        for (int outer = 0; outer < 10000; outer++) {

            // list = new ArrayList<Double>(10000); // BAD
            // list = new ArrayList<Double>(); // WORSE
            list.clear(); // BETTER

            for (int inner = 0; inner < 10000; inner++) {
                list.add(Math.random());
            }

            if (outer % 1000 == 0) {
                System.out.printf("Outer loop at %d%n", outer);
            }

        }
        System.out.printf("Done.%n");
    }
}

Using Java 1.6.0_24-b07 on a Windows 7 32 bit.

java -Xloggc:gc.log GarbageCollector

Then look at gc.log

• Triggered 444 times using BAD method
• Triggered 666 times using WORSE method
• Triggered 354 times using BETTER method

Now granted, this is not the best test or the best design but when faced with a situation where you have no choice but implementing such a loop or when dealing with existing code that behaves badly, choosing to reuse objects instead of creating new ones can reduce the number of times the garbage collector gets in the way...

you are doing several things wrong. The explanation follows the corrected code:

<label id="LblTextCount"></label>
<textarea name="text" onKeyPress="checkLength(this, 512, 'LblTextCount')">
</textarea>

Note the quotes around the id.

function checkLength(object, maxlength, label) {
    charsleft = (maxlength - object.value.length);

    // never allow to exceed the specified limit
    if( charsleft < 0 ) {
        object.value = object.value.substring(0, maxlength-1);
    }

    // set the value of charsleft into the label
    document.getElementById(label).innerHTML = charsleft;
}

First, on your key press event you need to send the label id as a string for it to read correctly. Second, InnerHTML has a lowercase i. Lastly, because you sent the function the string id you can get the element by that id.

Let me know how that works out for you

EDIT Not that by not declaring charsleft as a var, you are implicitly creating a global variable. a better way would be to do the following when declaring it in the function:

var charsleft = ....

I faced the same problem while executing a curl. I got it right when I changed the following in the php.ini file:

max_execution_time = 1000 ;

and also

max_input_time = 1000 ;

Probably your problem should be solved by making above two changes and restarting the apache server.

Even after changing the above the problem persists and if you think it's because of some database operation using mysql you can try changing this also:

mysql.connect_timeout = 1000 ; // this is not neccessary

All this should be changed in php.ini file and apache server should be restarted to see the changes.

You can use

ScrollViewer.HorizontalScrollBarVisibility="Visible"
ScrollViewer.VerticalScrollBarVisibility="Visible"

These are attached property of wpf. For more information

In MVC 4 you can do:

protected override JsonResult Json(object data, string contentType, System.Text.Encoding contentEncoding, JsonRequestBehavior behavior)
{
    return new JsonResult()
    {
        Data = data,
        ContentType = contentType,
        ContentEncoding = contentEncoding,
        JsonRequestBehavior = behavior,
        MaxJsonLength = Int32.MaxValue
    };
}

in your controller.

Addition:

For anyone puzzled by the parameters you need to specify, a call could look like this:

Json(
    new {
        field1 = true,
        field2 = "value"
        },
    "application/json",
    Encoding.UTF8,
    JsonRequestBehavior.AllowGet
);

Open your php.ini file use CNTRL+F to search for the following settings which may be the culprit:

• file_uploads
• upload_max_filesize
• post_max_size
• memory_limit
• max_input_time
• max_execution_time

Make sure to save a copy of the php.ini prior to making changes. You will want to adjust the settings to accommodate your file size, and increase input and/or execution time.

Remember to restart your services after making changes.

Warning! There may be some unforeseen drawbacks if you adjust these settings too liberally. I am not expert enough to know this for sure.

Implementation of accepted answer for Django:

import hashlib
from django.db import models


class MyModel(models.Model):
    file = models.FileField()  # any field based on django.core.files.File

    def get_hash(self):
        hash = hashlib.md5()
        for chunk in self.file.chunks(chunk_size=8192):
            hash.update(chunk)
        return hash.hexdigest()

For width it's easy, simply remove the width: 100% rule. By default, the div will stretch to fit the parent container.

Height is not quite so simple. You could do something like the equal height column trick.

html, body {width:100%;height:100%;margin:0;padding:0;}
.border {border:1px solid black;}
.margin { margin:5px;}
#one {width:500px;height:300px; overflow: hidden;}
#two {height:50px;}
#three {width:100px; padding-bottom: 30000px; margin-bottom: -30000px;}

To rebuild use:

ALTER INDEX __NAME_OF_INDEX__ ON __NAME_OF_TABLE__ REBUILD

or to reorganize use:

ALTER INDEX __NAME_OF_INDEX__ ON __NAME_OF_TABLE__ REORGANIZE

Reorganizing should be used at lower (<30%) fragmentations but only rebuilding (which is heavier to the database) cuts the fragmentation down to 0%.

from: http://www.codeproject.com/KB/WCF/WCF_Operation_Timeout_.aspx

To avoid this timeout error, we need to configure the OperationTimeout property for Proxy in the WCF client code. This configuration is something new unlike other configurations such as Send Timeout, Receive Timeout etc., which I discussed early in the article. To set this operation timeout property configuration, we have to cast our proxy to IContextChannel in WCF client application before calling the operation contract methods.

I know this is extremely late to the party, but now, in year 2013, we have a few media types to cover error handling in a common distributed (RESTful) fashion. See "vnd.error", application/vnd.error+json (https://github.com/blongden/vnd.error) and "Problem Details for HTTP APIs", application/problem+json (https://tools.ietf.org/html/draft-nottingham-http-problem-05).

You'll want something like this to increase the message size quotas, in the App.config or Web.config file:

<bindings>
    <basicHttpBinding>
        <binding name="basicHttp" allowCookies="true"
                 maxReceivedMessageSize="20000000" 
                 maxBufferSize="20000000"
                 maxBufferPoolSize="20000000">
            <readerQuotas maxDepth="32" 
                 maxArrayLength="200000000"
                 maxStringContentLength="200000000"/>
        </binding>
    </basicHttpBinding>
</bindings>

And use the binding name in your endpoint configuration e.g.

...
bindingConfiguration="basicHttp"
...

The justification for the values is simple, they are sufficiently large to accommodate most messages. You can tune that number to fit your needs. The low default value is basically there to prevent DOS type attacks. Making it 20000000 would allow for a distributed DOS attack to be effective, the default size of 64k would require a very large number of clients to overpower most servers these days.

I just did a very quick and dirty test on repl.it using Node v7.4. For a single character, the standard for loop is quickest:

Some code:

// winner!
function charCount1(s, c) {
    let count = 0;
    c = c.charAt(0); // we save some time here
    for(let i = 0; i < s.length; ++i) {
        if(c === s.charAt(i)) {
            ++count;
        }
    }
    return count;
}

function charCount2(s, c) {
    return (s.match(new RegExp(c[0], 'g')) || []).length;
}

function charCount3(s, c) {
    let count = 0;
    for(ch of s) {
        if(c === ch) {
            ++count;
        }
    }
    return count;
}

function perfIt() {
    const s = 'Hello, World!';
    const c = 'o';

    console.time('charCount1');
    for(let i = 0; i < 10000; i++) {
        charCount1(s, c);
    }
    console.timeEnd('charCount1');
    
    console.time('charCount2');
    for(let i = 0; i < 10000; i++) {
        charCount2(s, c);
    }
    console.timeEnd('charCount2');
    
    console.time('charCount3');
    for(let i = 0; i < 10000; i++) {
        charCount2(s, c);
    }
    console.timeEnd('charCount3');
}

Results from a few runs:

perfIt()
charCount1: 3.301ms
charCount2: 11.652ms
charCount3: 174.043ms
undefined

You can now use base64 files to produce sounds when imported as data URI. The solution is almost the same as the previous ones, except you do not need to import an external audio file.

And here is where you can convert mp3 or wav files into Data URI format:

This looks like Dijstra's algorithm. In any case, the time taken to run will depend on N. If it takes more than 3 seconds there isn't any way I can see of speeding it up, as all the calculations that it is doing need to be done.

Depending on what problem you're trying to solve, there might be a faster algorithm.

Simple like a piece of CAKE!

You can define a new column type like (L in this case) while maintaining the current alignment (c, r or l):

\documentclass{article}
\usepackage{array}
\newcolumntype{L}{>{\centering\arraybackslash}m{3cm}}

\begin{document}

\begin{table}
    \begin{tabular}{|c|L|L|}
        \hline
        Title 1 & Title 2 & Title 3 \\
        \hline 
        one-liner & multi-line and centered & \multicolumn{1}{m{3cm}|}{multi-line piece of text to show case a multi-line and justified cell}   \\
        \hline
        apple & orange & banana \\
        \hline
        apple & orange & banana \\
        \hline
    \end{tabular}
\end{table}
\end{document}

As you probably know, the maximum request length is configured in TWO places.

1. maxRequestLength - controlled at the ASP.NET app level
2. maxAllowedContentLength - under <system.webServer>, controlled at the IIS level

The first case is covered by other answers to this question.

To catch THE SECOND ONE you need to do this in global.asax:

protected void Application_EndRequest(object sender, EventArgs e)
{
    //check for the "file is too big" exception if thrown at the IIS level
    if (Response.StatusCode == 404 && Response.SubStatusCode == 13)
    {
        Response.Write("Too big a file"); //just an example
        Response.End();
    }
}

I just ran into this issue a couple minutes ago. I solved it by doing a better job at managing my listview adapter. I thought it was an issue with the hundreds of 50x50px images I was using, turns out I was trying to inflate my custom view each time the row was being shown. Simply by testing to see if the row had been inflated I eliminated this error, and I am using hundreds of bitmaps. This is actually for a Spinner, but the base adapter works all the same for a ListView. This simple fix also greatly improved the performance of the adapter.

@Override
public View getView(final int position, View convertView, final ViewGroup parent) {

    if(convertView == null){
        LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        convertView = inflater.inflate(R.layout.spinner_row, null);
    }
...

You also have to modify the minimum size of the data and log files. DBCC SHRINKDATABASE will shrink the data inside the files you already have allocated. To shrink a file to a size smaller than its minimum size, use DBCC SHRINKFILE and specify the new size.

I am almost sure you can split values across multiple INs using OR:

select * from table1 where ID in (1,2,3,4,...,1000) or 
ID in (1001,1002,...,2000)

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.

In some cases, managed code can actually be faster than native code. For instance, "mark-and-sweep" garbage collection algorithms allow environments like the JRE or CLR to free large numbers of short-lived (usually) objects in a single pass, where most C/C++ heap objects are freed one-at-a-time.

From wikipedia:

For many practical purposes, allocation/deallocation-intensive algorithms implemented in garbage collected languages can actually be faster than their equivalents using manual heap allocation. A major reason for this is that the garbage collector allows the runtime system to amortize allocation and deallocation operations in a potentially advantageous fashion.

That said, I've written a lot of C# and a lot of C++, and I've run a lot of benchmarks. In my experience, C++ is a lot faster than C#, in two ways: (1) if you take some code that you've written in C#, port it to C++ the native code tends to be faster. How much faster? Well, it varies a whole lot, but it's not uncommon to see a 100% speed improvement. (2) In some cases, garbage collection can massively slow down a managed application. The .NET CLR does a terrible job with large heaps (say, > 2GB), and can end up spending a lot of time in GC--even in applications that have few--or even no--objects of intermediate life spans.

Of course, in most cases that I've encounted, managed languages are fast enough, by a long shot, and the maintenance and coding tradeoff for the extra performance of C++ is simply not a good one.

Instead of:

void foo(char *s);
foo("constant string");

This works:

void foo(const char s[]);
foo("constant string");

You can't put a div directly inside a table, like this:

<!-- INVALID -->
<table>
  <div>
    Hello World
  </div>
</table>

Putting a div inside a td or th element is fine, however:

<!-- VALID -->
<table>
  <tr>
    <td>
      <div>
        Hello World
      </div>
    </td>
  </tr>
</table>

For Debian Jessie and Stretch installing the following packages resolves the issue:

sudo apt install libblas3 liblapack3 liblapack-dev libblas-dev

Your next issue is very likely going to be a missing Fortran compiler, resolve this by installing it like this:

sudo apt install gfortran

If you want an optimized scipy, you can also install the optional libatlas-base-dev package:

sudo apt install libatlas-base-dev

If you have any issue with a missing Python.h file like this:

Python.h: No such file or directory

Then have a look at this post: https://stackoverflow.com/a/21530768/209532

SELECT * FROM table
WHERE YEAR(date_created) = YEAR(CURRENT_DATE - INTERVAL 1 MONTH)
AND MONTH(date_created) = MONTH(CURRENT_DATE - INTERVAL 1 MONTH)

For flexibility and other places you might want to validated. You can use the following function.

`function validateOnlyTextField(element) {
    var str = element.value;
    if(!(/^[a-zA-Z, ]+$/.test(str))){
        // console.log('String contain number characters');
        str = str.substr(0,  str.length -1);
        element.value = str;
    }
}`

Then on your html section use the following event.

<input type="text" id="names" onkeyup="validateOnlyTextField(this)" />

You can always reuse the function.

In the beaten-up MVC pattern, the Servlet is "C" - controller.

Its main job is to do initial request evaluation and then dispatch the processing based on the initial evaluation to the specific worker. One of the worker's responsibilities may be to setup some presentation layer beans and forward the request to the JSP page to render HTML. So, for this reason alone, you need to pass the request object to the service layer.

I would not, though, start writing raw Servlet classes. The work they do is very predictable and boilerplate, something that framework does very well. Fortunately, there are many available, time-tested candidates ( in the alphabetical order ): Apache Wicket, Java Server Faces, Spring to name a few.

Uses Line Feeds and spaces as a good break point:

declare @sqlAll as nvarchar(max)
set @sqlAll = '-- Insert all your sql here'

print '@sqlAll - truncated over 4000'
print @sqlAll
print '   '
print '   '
print '   '

print '@sqlAll - split into chunks'
declare @i int = 1, @nextspace int = 0, @newline nchar(2)
set @newline = nchar(13) + nchar(10)


while Exists(Select(Substring(@sqlAll,@i,3000))) and (@i < LEN(@sqlAll))
begin
    while Substring(@sqlAll,@i+3000+@nextspace,1) <> ' ' and Substring(@sqlAll,@i+3000+@nextspace,1) <> @newline
    BEGIN
        set @nextspace = @nextspace + 1
    end
    print Substring(@sqlAll,@i,3000+@nextspace)
    set @i = @i+3000+@nextspace
    set @nextspace = 0
end
print '   '
print '   '
print '   '

If the response is in json you could do something like (python3):

import json
import requests as reqs

# Make the HTTP request.
response = reqs.get('http://demo.ckan.org/api/3/action/group_list')

# Use the json module to load CKAN's response into a dictionary.
response_dict = json.loads(response.text)

for i in response_dict:
    print("key: ", i, "val: ", response_dict[i])

To see everything in the response you can use .__dict__:

print(response.__dict__)

The answers are partially correct because @@ is actually a class variable which is per class hierarchy meaning it is shared by a class, its instances and its descendant classes and their instances.

class Person
  @@people = []

  def initialize
    @@people << self
  end

  def self.people
    @@people
  end
end

class Student < Person
end

class Graduate < Student
end

Person.new
Student.new

puts Graduate.people

This will output

#<Person:0x007fa70fa24870>
#<Student:0x007fa70fa24848>

So there is only one same @@variable for Person, Student and Graduate classes and all class and instance methods of these classes refer to the same variable.

There is another way of defining a class variable which is defined on a class object (Remember that each class is actually an instance of something which is actually the Class class but it is another story). You use @ notation instead of @@ but you can't access these variables from instance methods. You need to have class method wrappers.

class Person

  def initialize
    self.class.add_person self
  end

  def self.people
    @people
  end

  def self.add_person instance
    @people ||= []
    @people << instance
  end
end

class Student < Person
end

class Graduate < Student
end

Person.new
Person.new
Student.new
Student.new
Graduate.new
Graduate.new

puts Student.people.join(",")
puts Person.people.join(",")
puts Graduate.people.join(",")

Here, @people is single per class instead of class hierarchy because it is actually a variable stored on each class instance. This is the output:

#<Student:0x007f8e9d2267e8>,#<Student:0x007f8e9d21ff38>
#<Person:0x007f8e9d226158>,#<Person:0x007f8e9d226608>
#<Graduate:0x007f8e9d21fec0>,#<Graduate:0x007f8e9d21fdf8> 

One important difference is that, you cannot access these class variables (or class instance variables you can say) directly from instance methods because @people in an instance method would refer to an instance variable of that specific instance of the Person or Student or Graduate classes.

So while other answers correctly state that @myvariable (with single @ notation) is always an instance variable, it doesn't necessarily mean that it is not a single shared variable for all instances of that class.

By the way, instead of generating the x and y coordinates yourself, you can also use the curve() function, which is intended to draw curves corresponding to a function (such as the density of a standard normal function).

see

help(curve)

and its examples.

And if you want to add som text to properly label the mean and standard deviations, you can use the text() function (see also plotmath, for annotations with mathematical symbols) .

see

help(text)
help(plotmath)

You can use myDict.has_key(keyname) as well to validate if the key exists.

Edit based on the comments -

This would work only on versions lower than 3.1. has_key has been removed from Python 3.1. You should use the in operator if you are using Python 3.1

if (-e $base_path)
{ 
 # code
}

-e is the 'existence' operator in Perl.

You can check permissions and other attributes using the code on this page.

Only static functions are called with class name.

classname::Staicfunction();

Non static functions have to be called using objects.

classname obj;
obj.Somefunction();

This is exactly what your error means. Since your function is non static you have to use a object reference to invoke it.

You need to merge the remote branch into your current branch by running git pull.

If your local branch is already up-to-date, you may also need to run git pull --rebase.

A quick google search also turned up this same question asked by another SO user: Cannot push to GitHub - keeps saying need merge. More details there.

I found that stimulating an update in "natural" sequence was an easier route than force-pushing things.

Supposing that the repo is already created on github and you may have also put some stuff into the README.md .

1. On your computer, open terminal and git clone [repo URL]

2. You'll see a new folder will have been created bearing your repo's name. Feel free to rename it - doesn't matter.

3. Move your code, files etc into this folder. Edit the README.md if you have to.

4. Now open Terminal / command prompt, get inside that folder and do things as if you are making the next update to the repo:

git add .
git commit -m "v2"
git push origin master

Note: at the commit command git may reject, asking to configure the user email and password first. Follow the steps as given on screen, then run the commit command again.

5. And those three commands is what you do now onwards for every time you want to push another update.

Your solutions are correct but unnecessary complicated. You can use pure javascript filter function. This is your model:

     $scope.fishes = [{category:'freshwater', id:'1', name: 'trout', more:'false'},  {category:'freshwater', id:'2', name:'bass', more:'false'}];

And this is your function:

     $scope.showdetails = function(fish_id){
         var found = $scope.fishes.filter({id : fish_id});
         return found;
     };

You can also use expression:

     $scope.showdetails = function(fish_id){
         var found = $scope.fishes.filter(function(fish){ return fish.id === fish_id });
         return found;
     };

More about this function: LINK

I think you can also use a scaffold to do the white background. Here's some piece of code that may help.

import 'package:flutter/material.dart';
void main() => runApp(new MyApp());
class MyApp extends StatelessWidget {
  @override
    Widget build(BuildContext context) {

      return new MaterialApp(
        title: 'Testing',
        home: new Scaffold(
        //Here you can set what ever background color you need.
          backgroundColor: Colors.white,
        ),
      );
    }
}

Hope this helps .

Thanks a lot @sandeep for his answer.

My problem was that I want to show / hide text on span with mouse click. So by default short text with dots is shown and by clicking long text appears. Clicking again hides that long text and shows short one again.

Quite easy thing to do: just add / remove class with text-overflow:ellipsis.

HTML:

<span class="spanShortText cursorPointer"  onclick="fInventoryShippingReceiving.ShowHideTextOnSpan(this);">Some really long description here</span>

CSS (same as @sandeep with .cursorPointer added)

.spanShortText {
  display: inline-block;
  width: 100px;
  white-space: nowrap;
  overflow: hidden !important;
  text-overflow: ellipsis;
}

.cursorPointer {
  cursor: pointer;
}

JQuery part - basically just removes / adds class cSpanShortText.

  function ShowHideTextOnSpan(element) {
    var cSpanShortText = 'spanShortText';
    var $el = $(element);

      $el.addClass(cSpanShortText);

They are found on either one of the below locations depending on how chrome was installed

• When chrome is installed at the user level, it's located at:

~/Users/<username>/Library/Application\ Support/Google/Chrome/Default/Extensions

• When installed at the root level, it's at:

You are not adding the object to the session, instead you are adding it to the request.
What you need is:

HttpSession session = request.getSession();
session.setAttribute("MySessionVariable", param);

In Servlets you have 4 scopes where you can store data.

1. Application
2. Session
3. Request
4. Page

Make sure you understand these. For more look here

Do not create separate lists; create a list of lists:

results = []
with open('inputfile.txt') as inputfile:
    for line in inputfile:
        results.append(line.strip().split(','))

or better still, use the csv module:

import csv

results = []
with open('inputfile.txt', newline='') as inputfile:
    for row in csv.reader(inputfile):
        results.append(row)

Lists or dictionaries are far superiour structures to keep track of an arbitrary number of things read from a file.

Note that either loop also lets you address the rows of data individually without having to read all the contents of the file into memory either; instead of using results.append() just process that line right there.

Just for completeness sake, here's the one-liner compact version to read in a CSV file into a list in one go:

import csv

with open('inputfile.txt', newline='') as inputfile:
    results = list(csv.reader(inputfile))

This can also help to list procedure except the system procedures:

select * from sys.all_objects where type='p' and is_ms_shipped=0

If still someone is looking for all the data to be retrieved from Elasticsearch like me for some usecases, here is what I did. Moreover, all the data means, all the indexes and all the documents types. I'm using Elasticsearch 6.3

curl -X GET "localhost:9200/_search?pretty=true" -H 'Content-Type: application/json' -d'
{
    "query": {
        "match_all": {}
    }

I tried the above solutions but it didn't work for me, just incase there any other person in the same shoes, this is what I did. I updated apt-get with the following command

sudo add-apt-repository ppa:ondrej/php

this i installed with php curl for the version of php that i was using, mine was

sudo apt-get install php7.1-curl

This worked for me:

JSONArray jsonarr = (JSONArray) new JSONParser().parse(new InputStreamReader(Nameofclass.class.getResourceAsStream(pathToJSONFile)));
JSONObject jsonobj = (JSONObject) new JSONParser().parse(new InputStreamReader(Nameofclass.class.getResourceAsStream(pathToJSONFile)));

If none of the above answers works for you, try the following: Get the "org.eclipse.equinox.simpleconfigurator" and the "org.eclipse.update" folders found under the "eclipse\configuration" from a working Eclipse instance (can be the stock Eclipse downloaded from their website) and replace them in your Eclipse installation directory. This fixed it for me.

The biggest/largest integer that can be stored in a double without losing precision is the same as the largest possible value of a double. That is, DBL_MAX or approximately 1.8 × 10³⁰⁸ (if your double is an IEEE 754 64-bit double). It's an integer. It's represented exactly. What more do you want?

Go on, ask me what the largest integer is, such that it and all smaller integers can be stored in IEEE 64-bit doubles without losing precision. An IEEE 64-bit double has 52 bits of mantissa, so I think it's 2⁵³:

• 2⁵³ + 1 cannot be stored, because the 1 at the start and the 1 at the end have too many zeros in between.
• Anything less than 2⁵³ can be stored, with 52 bits explicitly stored in the mantissa, and then the exponent in effect giving you another one.
• 2⁵³ obviously can be stored, since it's a small power of 2.

Or another way of looking at it: once the bias has been taken off the exponent, and ignoring the sign bit as irrelevant to the question, the value stored by a double is a power of 2, plus a 52-bit integer multiplied by 2^{exponent - 52}. So with exponent 52 you can store all values from 2⁵² through to 2⁵³ - 1. Then with exponent 53, the next number you can store after 2⁵³ is 2⁵³ + 1 × 2^{53 - 52}. So loss of precision first occurs with 2⁵³ + 1.

JavaScript 1.2 was introduced with Netscape Navigator 4 in 1997. That version number only ever had significance for Netscape browsers. For example, Microsoft's implementation (as used in Internet Explorer) is called JScript, and has its own version numbering which bears no relation to Netscape's numbering.

The other difference is that

template<class T> ...

is allowed, but

template<struct T> ...

is not.

You are right, the documentation lacks of those methods. However when I dug into rxjs repository, I found nice comments about tap (too long to paste here) and pipe operators:

  /**
   * Used to stitch together functional operators into a chain.
   * @method pipe
   * @return {Observable} the Observable result of all of the operators having
   * been called in the order they were passed in.
   *
   * @example
   *
   * import { map, filter, scan } from 'rxjs/operators';
   *
   * Rx.Observable.interval(1000)
   *   .pipe(
   *     filter(x => x % 2 === 0),
   *     map(x => x + x),
   *     scan((acc, x) => acc + x)
   *   )
   *   .subscribe(x => console.log(x))
   */

In brief:

Pipe: Used to stitch together functional operators into a chain. Before we could just do observable.filter().map().scan(), but since every RxJS operator is a standalone function rather than an Observable's method, we need pipe() to make a chain of those operators (see example above).

Tap: Can perform side effects with observed data but does not modify the stream in any way. Formerly called do(). You can think of it as if observable was an array over time, then tap() would be an equivalent to Array.forEach().

Using UTC

ISO 8601 (MSDN datetime formats)

Console.WriteLine(DateTime.UtcNow.ToString("s") + "Z");

2009-11-13T10:39:35Z

The Z is there because

If the time is in UTC, add a 'Z' directly after the time without a space. 'Z' is the zone designator for the zero UTC offset. "09:30 UTC" is therefore represented as "09:30Z" or "0930Z". "14:45:15 UTC" would be "14:45:15Z" or "144515Z".

If you want to include an offset

int hours = TimeZoneInfo.Local.BaseUtcOffset.Hours;
string offset = string.Format("{0}{1}",((hours >0)? "+" :""),hours.ToString("00"));
string isoformat = DateTime.Now.ToString("s") + offset;
Console.WriteLine(isoformat);

Two things to note: + or - is needed after the time but obviously + doesn't show on positive numbers. According to wikipedia the offset can be in +hh format or +hh:mm. I've kept to just hours.

As far as I know, RFC1123 (HTTP date, the "u" formatter) isn't meant to give time zone offsets. All times are intended to be GMT/UTC.

Try this:

<img v-bind:src="'/media/avatars/' + joke.avatar" /> 

Don't forget single quote around your path string. also in your data check you have correctly defined image variable.

joke: {
  avatar: 'image.jpg'
}

A working demo here: http://jsbin.com/pivecunode/1/edit?html,js,output

Many popular Java webapps, including Jenkins and Nexus, use this mechanism:

1. Optionally, check a servlet context-param / init-param. This allows configuring multiple webapp instances per servlet container, using context.xml which can be done by modifying the WAR or by changing server settings (in case of Tomcat).

2. Check an environment variable (using System.getenv), if it is set, then use that folder as your application data folder. e.g. Jenkins uses JENKINS_HOME and Nexus uses PLEXUS_NEXUS_WORK. This allows flexible configuration without any changes to WAR.

3. Otherwise, use a subfolder inside user's home folder, e.g. $HOME/.yourapp. In Java code this will be:

   final File appFolder = new File(System.getProperty("user.home"), ".yourapp");
   

I would try the program screen.

In .NET 4.5 the ZipFile.CreateFromDirectory(startPath, zipPath); method does not cover a scenario where you wish to zip a number of files and sub-folders without having to put them within a folder. This is valid when you wish the unzip to put the files directly within the current folder.

This code worked for me:

public static class FileExtensions
{
    public static IEnumerable<FileSystemInfo> AllFilesAndFolders(this DirectoryInfo dir)
    {
        foreach (var f in dir.GetFiles())
            yield return f;
        foreach (var d in dir.GetDirectories())
        {
            yield return d;
            foreach (var o in AllFilesAndFolders(d))
                yield return o;
        }
    }
}

void Test()
{
    DirectoryInfo from = new DirectoryInfo(@"C:\Test");
    using (FileStream zipToOpen = new FileStream(@"Test.zip", FileMode.Create))
    {
        using (ZipArchive archive = new ZipArchive(zipToOpen, ZipArchiveMode.Create))
        {
            foreach (FileInfo file in from.AllFilesAndFolders().Where(o => o is FileInfo).Cast<FileInfo>())
            {
                var relPath = file.FullName.Substring(from.FullName.Length+1);
                ZipArchiveEntry readmeEntry = archive.CreateEntryFromFile(file.FullName, relPath);
            }
        }
    }
}

Folders don't need to be "created" in the zip-archive. The second parameter "entryName" in CreateEntryFromFile should be a relative path, and when unpacking the zip-file the directories of the relative paths will be detected and created.

Simple date example using $filter in a controller would be:

var myDate = new Date();
$scope.dateAsString = $filter('date')(myDate, "yyyy-MM-dd"); 

As explained here - https://stackoverflow.com/a/20131782/262140

SQlite does not have a specific datetime type. You can use TEXT, REAL or INTEGER types, whichever suits your needs.

Straight from the DOCS

SQLite does not have a storage class set aside for storing dates and/or times. Instead, the built-in Date And Time Functions of SQLite are capable of storing dates and times as TEXT, REAL, or INTEGER values:

• TEXT as ISO8601 strings ("YYYY-MM-DD HH:MM:SS.SSS").
• REAL as Julian day numbers, the number of days since noon in Greenwich on November 24, 4714 B.C. according to the proleptic Gregorian calendar.
• INTEGER as Unix Time, the number of seconds since 1970-01-01 00:00:00 UTC.

Applications can chose to store dates and times in any of these formats and freely convert between formats using the built-in date and time functions.

SQLite built-in Date and Time functions can be found here.

There are two ways to do this:

CSS: Use width as %, like 75%, so the width of the div will change automatically when user resizes the browser.

Javascipt: Use resize event

$(window).bind('resize', function()
{
    if($(window).width() > 500)
        $('#divID').css('width', '300px');
    else
        $('divID').css('width', '200px');
});

Hope this will help you :)

Check out this implementation of PHP's strtotime() in JavaScript!

I found that it works identically to PHP for everything that I threw at it.

Update: this function as per version 1.0.2 can't handle this case: '2007:07:20 20:52:45' (Note the : separator for year and month)

Update 2018:

This is now available as an npm module! Simply npm install locutus and then in your source:

var strtotime = require('locutus/php/datetime/strtotime');

I currently have a workaround functional (it passes my unit tests). It is a good solution to my opinion when you only want to add a limited number of fields from other models.

Am I missing something here ?

class UserProfileForm(ModelForm):
    def __init__(self, instance=None, *args, **kwargs):
        # Add these fields from the user object
        _fields = ('first_name', 'last_name', 'email',)
        # Retrieve initial (current) data from the user object
        _initial = model_to_dict(instance.user, _fields) if instance is not None else {}
        # Pass the initial data to the base
        super(UserProfileForm, self).__init__(initial=_initial, instance=instance, *args, **kwargs)
        # Retrieve the fields from the user model and update the fields with it
        self.fields.update(fields_for_model(User, _fields))

    class Meta:
        model = UserProfile
        exclude = ('user',)

    def save(self, *args, **kwargs):
        u = self.instance.user
        u.first_name = self.cleaned_data['first_name']
        u.last_name = self.cleaned_data['last_name']
        u.email = self.cleaned_data['email']
        u.save()
        profile = super(UserProfileForm, self).save(*args,**kwargs)
        return profile

(Update September 2012):

MRT points out in the comments that "Eclipse Version" question references a .eclipseproduct in the main folder, and it contains:

name=Eclipse Platform
id=org.eclipse.platform
version=3.x.0

So that seems more straightforward than my original answer below.

Also, Neeme Praks mentions below that there is a eclipse/configuration/config.ini which includes a line like:

eclipse.buildId=4.4.1.M20140925-0400

Again easier to find, as those are Java properties set and found with System.getProperty("eclipse.buildId").

Original answer (April 2009)

For Eclipse Helios 3.6, you can deduce the Eclipse Platform version directly from the About screen:
It is a combination of the Eclipse global version and the build Id:

Here is an example for Eclipse 3.6M6:
The version would be: 3.6.0.v201003121448, after the version 3.6.0 and the build Id I20100312-1448 (an Integration build from March 12th, 2010 at 14h48

To see it more easily, click on "Plugin Details" and sort by Version.

Note: Eclipse3.6 has a brand new cool logo:

And you can see the build Id now being displayed during the loading step of the different plugin.

As you are referring to a combobox, I'm assuming you don't want to use 2-way databinding (if so, look at using a BindingList)

public class Country
{
    public string Name { get; set; }
    public IList<City> Cities { get; set; }
    public Country(string _name)
    {
        Cities = new List<City>();
        Name = _name;
    }
}

List<Country> countries = new List<Country> { new Country("UK"), 
                                     new Country("Australia"), 
                                     new Country("France") };

var bindingSource1 = new BindingSource();
bindingSource1.DataSource = countries;

comboBox1.DataSource = bindingSource1.DataSource;

comboBox1.DisplayMember = "Name";
comboBox1.ValueMember = "Name";

To find the country selected in the bound combobox, you would do something like: Country country = (Country)comboBox1.SelectedItem;.

If you want the ComboBox to dynamically update you'll need to make sure that the data structure that you have set as the DataSource implements IBindingList; one such structure is BindingList<T>.

Tip: make sure that you are binding the DisplayMember to a Property on the class and not a public field. If you class uses public string Name { get; set; } it will work but if it uses public string Name; it will not be able to access the value and instead will display the object type for each line in the combo box.

I did this:

$('#myModal').on 'shown.bs.modal', (e) ->  
  $(e.target).find('.modal-body').load('http://yourserver.com/content')

I tried 2 solutions, both work.

Solution_1

.yml

available-users-list:
  configurations:
    -
      username: eXvn817zDinHun2QLQ==
      password: IP2qP+BQfWKJMVeY7Q==
    -
      username: uwJlOl/jP6/fZLMm0w==
      password: IP2qP+BQKJLIMVeY7Q==

LoginInfos.java

@ConfigurationProperties(prefix = "available-users-list")
@Configuration
@Component
@Data
public class LoginInfos {
    private List<LoginInfo> configurations;

    @Data
    public static class LoginInfo {
        private String username;
        private String password;
    }

}

List<LoginInfos.LoginInfo> list = loginInfos.getConfigurations();

Solution_2

.yml

available-users-list: '[{"username":"eXvn817zHBVn2QLQ==","password":"IfWKJLIMVeY7Q=="}, {"username":"uwJlOl/g9jP6/0w==","password":"IP2qWKJLIMVeY7Q=="}]'

Java

@Value("${available-users-listt}")
String testList;

ObjectMapper mapper = new ObjectMapper();
LoginInfos.LoginInfo[] array = mapper.readValue(testList, LoginInfos.LoginInfo[].class);

I just found the "-fae" parameter, which causes Maven to run all tests and not stop on failure.

just simply press enter it make a break

you must be using old version of wget i had same issue. i was using wget 1.12.so to solve this issue there are 2 way: Update wget or use curl

curl -LO 'https://example.com/filename.tar.gz'

One method I did with mine, is to "Add to Source Control", and select 'Git'.

You say that you have profiled the application. Have you profiled the ORM too? There is an EF profiler from Ayende that will highlight where you can optimise your EF code. You can find it here:

http://efprof.com/

Remember that you can use a traditional SQL approach alongside your ORM if you need to to gain performance.

If there a faster/better ORM? Depending on your object/data model, you could consider using a one of the micro-ORMs, such as Dapper, Massive or PetaPoco.

The Dapper site publishes some comparitive benchmarks that will give you an idea how they compare to other ORMs. But it's worth noting that the micro-ORMs do not support the rich feature set of the full ORMs like EF and NH.

You may want to take a look at RavenDB. This is a non-relational database (from Ayende again) that lets you store POCOs directly with no mapping needed. RavenDB is optimised for reads and makes the developers life a whole lot easier by removing need to manipulate schema and to map your objects to that schema. However, be aware that this is a significantly different approach to using an ORM approach and these are outlined in the product's site.

You don't give a reproducible example but your warning message tells you exactly what the problem is.

memb only has a length of 10. I'm guessing the length of dih_y2$MemberID isn't a multiple of 10. When using ==, R spits out a warning if it isn't a multiple to let you know that it's probably not doing what you're expecting it to do. == does element-wise checking for equality. I suspect what you want to do is find which of the elements of dih_y2$MemberID are also in the vector memb. To do this you would want to use the %in% operator.

dih_col <- which(dih_y2$MemeberID %in% memb)

1. Create a empty win32 console application c++
2. Download a package called NupenGL Core from Nuget package manager (PM->"Install-Package nupengl.core") except glm everything is configured
3. create Source.cpp and start working Happy Coding

Have you tried using Project > Clean... from the menu? This will force a new build on the selected projects in Eclipse.

For those working on fragments and it disappeared after setting toolbar.getBackground().setAlpha(0); or any disappearance, i think you have to bring your AppBarLayout to the last in the xml, so its Fragment then AppBarLayout then relativelayout/constraint/linear whichever u use.

Or if your exception is thrown from the constructor of a class:

@Rule
public ExpectedException exception = ExpectedException.none();

@Test
public void myTest() {    

    exception.expect(MyException.class);
    CustomClass myClass= mock(CustomClass.class);
    doThrow(new MyException("constructor failed")).when(myClass);  

}

This can be done in a generic way and can be very useful when debugging a complex makefile. Following the same technique as described in another answer, you can insert the following into any makefile:

# if the first command line argument is "print"
ifeq ($(firstword $(MAKECMDGOALS)),print)

  # take the rest of the arguments as variable names
  VAR_NAMES := $(wordlist 2,$(words $(MAKECMDGOALS)),$(MAKECMDGOALS))

  # turn them into do-nothing targets
  $(eval $(VAR_NAMES):;@:))

  # then print them
  .PHONY: print
  print:
          @$(foreach var,$(VAR_NAMES),\
            echo '$(var) = $($(var))';)
endif

Then you can just do "make print" to dump the value of any variable:

$ make print CXXFLAGS
CXXFLAGS = -g -Wall

Here is a sample to find if there are match elements in another list

List<int> nums1 = new List<int> { 2, 4, 6, 8, 10 };
List<int> nums2 = new List<int> { 1, 3, 6, 9, 12};

if (nums1.Any(x => nums2.Any(y => y == x)))
{
    Console.WriteLine("There are equal elements");
}
else
{
    Console.WriteLine("No Match Found!");
}

Here's what worked for me:

git diff origin/master...

This shows only the changes between my currently selected local branch and the remote master branch, and ignores all changes in my local branch that came from merge commits.

A simple way of looking at HTTP 301 vs. 302 redirects is:

Suppose you have a bookmark to "http://sample.com/sample". You use a browser to go there.

A 302 redirect to a different URL at this point would mean that you should keep your bookmark to "http://sample.com/sample". This is because the destination URL may change in the future.

A 301 redirect to a different URL would mean that your bookmark should change to point to the new URL as it is a permanent redirect.

I had a similar experience with using SMO via C# with the stack trace:

[1896] System.IndexOutOfRangeException: Index was outside the bounds of the array. 
[1896]    at Microsoft.SqlServer.Management.Smo.BitStorage.SetBit(Int32 itemIndex, BitIndex bitIndex, Boolean value)

It turned out my versions of the CLR/NCLI/SMO were 10.50.1600.1. Upgrading them to 10.53.6000.34 fixed it - thus allowing the 2008R2 SMO to do many things with 2012 and 2014 servers.

You can use the 'expect' script on unix/terminal

For example create 'test.exp' :

#!/usr/bin/expect
        spawn scp  /usr/bin/file.txt root@<ServerLocation>:/home
        set pass "Your_Password"
        expect {
        password: {send "$pass\r"; exp_continue}
                  }

run the script

expect test.exp 

I hope that helps.

1. Use an event handler to notify other the form to handle it.
2. Create a public property on the child form and access it from parent form (with a valid cast).
3. Create another constructor on the child form for setting form's initialization parameters
4. Create custom events and/or use (static) classes.

The best practice would be #4 if you are using non-modal forms.

This was driving me crazy, but it seems that aularon's edit was missing the colon after "Vary". So changing "Vary Accept-Encoding" to "Vary: Accept-Encoding" fixed the issue for me.

I would have commented below the post, but it doesn't seem like it will let me.

Anyhow, I hope this saves someone the same trouble I was having.

PostGIS_Lib_Version(); - returns the version number of the PostGIS library.

http://postgis.refractions.net/docs/PostGIS_Lib_Version.html

Try:

printf "%X\n" ${MY_NUMBER}

Harder Way (learning purpose) :

var number = 150
var percent= 10
var result = 0
for (var index = 0; index < number; index++) {
   const calculate = index / number * 100
   if (calculate == percent) result += index
}
return result

Doing it in one bulk read:

import re

textfile = open(filename, 'r')
filetext = textfile.read()
textfile.close()
matches = re.findall("(<(\d{4,5})>)?", filetext)

Line by line:

import re

textfile = open(filename, 'r')
matches = []
reg = re.compile("(<(\d{4,5})>)?")
for line in textfile:
    matches += reg.findall(line)
textfile.close()

But again, the matches that returns will not be useful for anything except counting unless you added an offset counter:

import re

textfile = open(filename, 'r')
matches = []
offset = 0
reg = re.compile("(<(\d{4,5})>)?")
for line in textfile:
    matches += [(reg.findall(line),offset)]
    offset += len(line)
textfile.close()

But it still just makes more sense to read the whole file in at once.

I know this is not completely Vim. But I find the cscope integration really good, and it helps me a lot when hacking the Linux kernel.

• Ctrl + \, g to reach the definition of a function

• Ctrl + \, s to find all the usages of a function, macro, or variable.

As far as I know you can't do that, I may be wrong. However I'd do this with php, generate a JPEG using php standard functions and then display the image, should not be a very hard job, however depends on how flashy the contents of the DIV are

>>> x = "2342.34"
>>> float(x)
2342.3400000000001

There you go. Use float (which behaves like and has the same precision as a C,C++, or Java double).

If you already have a table and can't/don't want to recreate it for whatever reason, use indexes:

CREATE UNIQUE INDEX my_index ON my_table(col_1, col_2);

In a nutshell :

List/Array Sort() :

• Unstable sort.
• Done in-place.
• Use Introsort/Quicksort.
• Custom comparison is done by providing a comparer. If comparison is expensive, it might be slower than OrderBy() (which allow to use keys, see below).

OrderBy/ThenBy() :

• Stable sort.
• Not in-place.
• Use Quicksort. Quicksort is not a stable sort. Here is the trick : when sorting, if two elements have equal key, it compares their initial order (which has been stored before sorting).
• Allows to use keys (using lambdas) to sort elements on their values (eg : x => x.Id). All keys are extracted first before sorting. This might result in better performance than using Sort() and a custom comparer.

Sources: MDSN, reference source and dotnet/coreclr repository (GitHub).

Some of the statements listed above are based on current .NET framework implementation (4.7.2). It might change in the future.

Why not use document.documentMode only available under IE:

var doc = $window.document;
if (!!doc.documentMode)
{
  if (doc.documentMode === 10)
  {
    doc.documentElement.className += ' isIE isIE10';
  }
  else if (doc.documentMode === 11)
  {
    doc.documentElement.className += ' isIE isIE11';
  }
  // etc.
}

You can set a JavaScript variable in your WepPage that gets set once it's been loaded. You could put it anywhere, but if you're using jQuery, $(document).onReady isn't a bad place to start. If not, then you can put it in a <script> tag at the bottom of the page.

The advantage of this method as opposed to checking for element visibility is that you know the exact state of the page after the wait statement executes.

MyWebPage.html

... All my page content ...
<script> window.TestReady = true; </script></body></html>

And in your test (C# example):

// The timespan determines how long to wait for any 'condition' to return a value
// If it is exceeded an exception is thrown.
WebDriverWait wait = new WebDriverWait(driver, TimeSpan.FromSeconds(5.0));

// Set the 'condition' as an anonymous function returning a boolean
wait.Until<Boolean>(delegate(IWebDriver d)
{
    // Check if our global variable is initialized by running a little JS
    return (Boolean)((IJavaScriptExecutor)d).ExecuteScript("return typeof(window.TestReady) !== 'undefined' && window.TestReady === true");
});

Wildcard method: Add the following entry into your DNS server and change the domain and IP address accordingly.

*.example.com IN A 1.2.3.4

Sometimes it also happens when the function need to be executed in main thread only, so you can fix it by assigning it to the main thread as follows :-

DispatchQueue.main.async{

I have an extension method for Uri that:

• Accepts anonymous objects: uri.WithQuery(new { name = "value" })
• Accepts collections of string/string pairs (e.g. Dictionary`2).
• Accepts collections of string/object pairs (e.g. RouteValueDictionary).
• Accepts NameValueCollections.
• Sorts the query values by key so the same values produce equal URIs.
• Supports multiple values per key, preserving their original order.

The documented version can be found here.

The extension:

public static Uri WithQuery(this Uri uri, object values)
{
    if (uri == null)
        throw new ArgumentNullException(nameof(uri));

    if (values != null)
    {
        var query = string.Join(
            "&", from p in ParseQueryValues(values)
                 where !string.IsNullOrWhiteSpace(p.Key)
                 let k = HttpUtility.UrlEncode(p.Key.Trim())
                 let v = HttpUtility.UrlEncode(p.Value)
                 orderby k
                 select string.IsNullOrEmpty(v) ? k : $"{k}={v}");

        if (query.Length != 0 || uri.Query.Length != 0)
            uri = new UriBuilder(uri) { Query = query }.Uri;
    }

    return uri;
}

The query parser:

private static IEnumerable<KeyValuePair<string, string>> ParseQueryValues(object values)
{
    // Check if a name/value collection.
    var nvc = values as NameValueCollection;
    if (nvc != null)
        return from key in nvc.AllKeys
               from val in nvc.GetValues(key)
               select new KeyValuePair<string, string>(key, val);

    // Check if a string/string dictionary.
    var ssd = values as IEnumerable<KeyValuePair<string, string>>;
    if (ssd != null)
        return ssd;

    // Check if a string/object dictionary.
    var sod = values as IEnumerable<KeyValuePair<string, object>>;
    if (sod == null)
    {
        // Check if a non-generic dictionary.
        var ngd = values as IDictionary;
        if (ngd != null)
            sod = ngd.Cast<dynamic>().ToDictionary<dynamic, string, object>(
                p => p.Key.ToString(), p => p.Value as object);

        // Convert object properties to dictionary.
        if (sod == null)
            sod = new RouteValueDictionary(values);
    }

    // Normalize and return the values.
    return from pair in sod
           from val in pair.Value as IEnumerable<string>
            ?? new[] { pair.Value?.ToString() }
           select new KeyValuePair<string, string>(pair.Key, val);
}

Here are the tests:

var uri = new Uri("https://stackoverflow.com/yo?oldKey=oldValue");

// Test with a string/string dictionary.
var q = uri.WithQuery(new Dictionary<string, string>
{
    ["k1"] = string.Empty,
    ["k2"] = null,
    ["k3"] = "v3"
});

Debug.Assert(q == new Uri(
    "https://stackoverflow.com/yo?k1&k2&k3=v3"));

// Test with a string/object dictionary.
q = uri.WithQuery(new Dictionary<string, object>
{
    ["k1"] = "v1",
    ["k2"] = new[] { "v2a", "v2b" },
    ["k3"] = null
});

Debug.Assert(q == new Uri(
    "https://stackoverflow.com/yo?k1=v1&k2=v2a&k2=v2b&k3"));

// Test with a name/value collection.
var nvc = new NameValueCollection()
{
    ["k1"] = string.Empty,
    ["k2"] = "v2a"
};

nvc.Add("k2", "v2b");

q = uri.WithQuery(nvc);
Debug.Assert(q == new Uri(
    "https://stackoverflow.com/yo?k1&k2=v2a&k2=v2b"));

// Test with any dictionary.
q = uri.WithQuery(new Dictionary<int, HashSet<string>>
{
    [1] = new HashSet<string> { "v1" },
    [2] = new HashSet<string> { "v2a", "v2b" },
    [3] = null
});

Debug.Assert(q == new Uri(
    "https://stackoverflow.com/yo?1=v1&2=v2a&2=v2b&3"));

// Test with an anonymous object.
q = uri.WithQuery(new
{
    k1 = "v1",
    k2 = new[] { "v2a", "v2b" },
    k3 = new List<string> { "v3" },
    k4 = true,
    k5 = null as Queue<string>
});

Debug.Assert(q == new Uri(
    "https://stackoverflow.com/yo?k1=v1&k2=v2a&k2=v2b&k3=v3&k4=True&k5"));

// Keep existing query using a name/value collection.
nvc = HttpUtility.ParseQueryString(uri.Query);
nvc.Add("newKey", "newValue");

q = uri.WithQuery(nvc);
Debug.Assert(q == new Uri(
    "https://stackoverflow.com/yo?newKey=newValue&oldKey=oldValue"));

// Merge two query objects using the RouteValueDictionary.
var an1 = new { k1 = "v1" };
var an2 = new { k2 = "v2" };

q = uri.WithQuery(
    new RouteValueDictionary(an1).Concat(
        new RouteValueDictionary(an2)));

Debug.Assert(q == new Uri(
    "https://stackoverflow.com/yo?k1=v1&k2=v2"));

you should check if it is less than 10... not looking for the length of it , because this is a number and not a string

Another extension method for Linq-to-Objects, without using GroupBy:

    /// <summary>
    /// Returns the set of items, made distinct by the selected value.
    /// </summary>
    /// <typeparam name="TSource">The type of the source.</typeparam>
    /// <typeparam name="TResult">The type of the result.</typeparam>
    /// <param name="source">The source collection.</param>
    /// <param name="selector">A function that selects a value to determine unique results.</param>
    /// <returns>IEnumerable&lt;TSource&gt;.</returns>
    public static IEnumerable<TSource> Distinct<TSource, TResult>(this IEnumerable<TSource> source, Func<TSource, TResult> selector)
    {
        HashSet<TResult> set = new HashSet<TResult>();

        foreach(var item in source)
        {
            var selectedValue = selector(item);

            if (set.Add(selectedValue))
                yield return item;
        }
    }

Floating point numbers differ from real numbers in that for any given floating point number there is a next higher floating point number. Same as integers. There's no integer between 1 and 2.

There's no way to represent 1/3 as a float. There's a float below it and there's a float above it, and there's a certain distance between them. And 1/3 is in that space.

Apfloat for Java claims to work with arbitrary precision floating point numbers, but I've never used it. Probably worth a look. http://www.apfloat.org/apfloat_java/

A similar question was asked here before Java floating point high precision library

I want to mention the Ning Async Http Client Library. I've never used it but my colleague raves about it as compared to the Apache Http Client, which I've always used in the past. I was particularly interested to learn it is based on Netty, the high-performance asynchronous i/o framework, with which I am more familiar and hold in high esteem.

private static final String hostExtractorRegexString = "(?:https?://)?(?:www\\.)?(.+\\.)(com|au\\.uk|co\\.in|be|in|uk|org\\.in|org|net|edu|gov|mil)";
private static final Pattern hostExtractorRegexPattern = Pattern.compile(hostExtractorRegexString);

public static String getDomainName(String url){
    if (url == null) return null;
    url = url.trim();
    Matcher m = hostExtractorRegexPattern.matcher(url);
    if(m.find() && m.groupCount() == 2) {
        return m.group(1) + m.group(2);
    }
    return null;
}

Explanation : The regex has 4 groups. The first two are non-matching groups and the next two are matching groups.

The first non-matching group is "http" or "https" or ""

The second non-matching group is "www." or ""

The second matching group is the top level domain

The first matching group is anything after the non-matching groups and anything before the top level domain

The concatenation of the two matching groups will give us the domain/host name.

PS : Note that you can add any number of supported domains to the regex.

   .search-table-outter {border:2px solid red; overflow-x:scroll;}
   .search-table{table-layout: fixed; margin:40px auto 0px auto;   }
   .search-table, td, th{border-collapse:collapse; border:1px solid #777;}
   th{padding:20px 7px; font-size:15px; color:#444; background:#66C2E0;}
   td{padding:5px 10px; height:35px;}

You should provide scroll in div.

CSS Only:

Thinking about it on my way to the supermarket, you could of course also skip the entire image map idea, and make use of :hover on the elements on top of the image (changed the divs to a-blocks). Which makes things hell of a lot simpler, no jQuery needed...

Short explanation:

• Image is in the bottom
• 2 x a with display:block and absolute positioning + opacity:0
• Set opacity to 0.2 on hover

Example:

.area {_x000D_
    background:#fff;_x000D_
    display:block;_x000D_
    height:475px;_x000D_
    opacity:0;_x000D_
    position:absolute;_x000D_
    width:320px;_x000D_
}_x000D_
#area2 {_x000D_
    left:320px;_x000D_
}_x000D_
#area1:hover, #area2:hover {_x000D_
    opacity:0.2;_x000D_
}

<a id="area1" class="area" href="#"></a>_x000D_
<a id="area2" class="area" href="#"></a>_x000D_

Original Answer using jQuery

I just created something similar with jQuery, I don't think it can be done with CSS only.

Short explanation:

• Image is in the bottom
• Divs with rollover (image or color) with absolute positioning + display:none
• Transparent gif with the actual #map is on top (absolute position) (to prevent call to mouseout when the rollovers appear)
• jQuery is used to show/hide the divs

    $(document).ready(function() {_x000D_
        if($('#location-map')) {_x000D_
            $('#location-map area').each(function() {_x000D_
                var id = $(this).attr('id');_x000D_
                $(this).mouseover(function() {_x000D_

Hope it helps..

It is valid. You can, for example, use it to show modals (or similar things that respond to data-toggle and data-target attributes).

Something like:

<a role="button" data-toggle="modal" data-target=".bs-example-modal-sm" aria-hidden="true"><i class="fa fa-phone"></i></a>

Here I use the font-awesome icon, which is better as a a tag rather than a button, to show a modal. Also, setting role="button" makes the pointer change to an action type. Without either href or role="button", the cursor pointer does not change.

exec is shelling to the operating system, and unless the OS has some special way of knowing how to execute a file, then it's going to default to treating it as a shell script or similar. In this case, it has no idea how to run your php file. If this script absolutely has to be executed from a shell, then either execute php passing the filename as a parameter, e.g

exec ('/usr/local/bin/php -f /opt/lampp/htdocs/.../name.php)') ;

or use the punct at the top of your php script

#!/usr/local/bin/php
<?php ... ?>

• Lets say 1st component is DbstatsMainComponent
• 2nd component DbstatsGraphComponent.
• 1st component calling the method of 2nd

<button (click)="dbgraph.displayTableGraph()">Graph</button> <dbstats-graph #dbgraph></dbstats-graph>

Note the local variable #dbgraph on the child component, which the parent can use to access its methods (dbgraph.displayTableGraph()).

JavaScript

function playAudio(url) {
  new Audio(url).play();

Supported in most modern browsers and easy to embed into HTML elements.

After installing and configuring Hadoop, you can quickly run the command netstat -tulpn

to find the ports open. In the new version of Hadoop 3.1.3 the ports are as follows:-

localhost:8042 Hadoop, localhost:9870 HDFS, localhost:8088 YARN

AFAIK, fragments cannot hold other fragments.

UPDATE

With current versions of the Android Support package -- or native fragments on API Level 17 and higher -- you can nest fragments, by means of getChildFragmentManager(). Note that this means that you need to use the Android Support package version of fragments on API Levels 11-16, because even though there is a native version of fragments on those devices, that version does not have getChildFragmentManager().

npm is automatically installed with Node.js in the latest version of Node.js. What do you see when you type node --version and npm --version in the terminal?

You can upgrade npm using npm itself as well:

[sudo] npm install -g npm

Nesting (and) closures

Using closures for maintaining the scope of variables (in our case, the success callback function parameters) is the natural JavaScript solution. With promises, we can arbitrarily nest and flatten .then() callbacks - they are semantically equivalent, except for the scope of the inner one.

function getExample() {
    return promiseA(…).then(function(resultA) {
        // some processing
        return promiseB(…).then(function(resultB) {
            // more processing
            return // something using both resultA and resultB;
        });
    });
}

Of course, this is building an indentation pyramid. If indentation is getting too large, you still can apply the old tools to counter the pyramid of doom: modularize, use extra named functions, and flatten the promise chain as soon as you don't need a variable any more.
In theory, you can always avoid more than two levels of nesting (by making all closures explicit), in practise use as many as are reasonable.

function getExample() {
    // preprocessing
    return promiseA(…).then(makeAhandler(…));
}
function makeAhandler(…)
    return function(resultA) {
        // some processing
        return promiseB(…).then(makeBhandler(resultA, …));
    };
}
function makeBhandler(resultA, …) {
    return function(resultB) {
        // more processing
        return // anything that uses the variables in scope
    };
}

You can also use helper functions for this kind of partial application, like _.partial from Underscore/lodash or the native .bind() method, to further decrease indentation:

function getExample() {
    // preprocessing
    return promiseA(…).then(handlerA);
}
function handlerA(resultA) {
    // some processing
    return promiseB(…).then(handlerB.bind(null, resultA));
}
function handlerB(resultA, resultB) {
    // more processing
    return // anything that uses resultA and resultB
}

I see that this is a very old question, but this is how I calculate the percentage difference between 2 numbers:

(1 - (oldNumber / newNumber)) * 100

So, the percentage difference from 30 to 40 is:

(1 - (30/40)) * 100 = +25% (meaning, increase by 25%)

The percentage difference from 40 to 30 is:

(1 - (40/30)) * 100 = -33.33% (meaning, decrease by 33%)

In php, I use a function like this:

function calculatePercentage($oldFigure, $newFigure) {
        if (($oldFigure != 0) && ($newFigure != 0)) {
            $percentChange = (1 - $oldFigure / $newFigure) * 100;
        }
        else {
            $percentChange = null;
        }
        return $percentChange;
}

One can use Redirect too for this purpose

Redirect 301 / www.example.com/store

Or Alias for mapping

Alias / /store

Edit: mod_alias is only applicable in httpd.conf.

Even though this did not work when the OP asked this question, I think, for modern browsers at least, the best solution is to use display: flex or pseudo classes.

You can see an example in the following fiddle. Here is the updated fiddle.

For pseudo classes an example could be:

.centerPseudo {
    display:inline-block;
    text-align:center;
}

.centerPseudo::before{
    content:'';
    display:inline-block;
    height:100%;
    vertical-align:middle;
    width:0px;
}

The usage of display: flex, according to css-tricks and MDN is as follows:

.centerFlex {
  align-items: center;
  display: flex;
  justify-content: center;
}

There are other attributes available for flex, which are explained in above mentioned links, with further examples.

If you have to support older browsers, which don't support css3, then you should probably use javascript or the fixed width/height solution shown in the other answers.

Do it with toolbar.setTitleTextAppearance(context, R.style.TitleTextStyle);

//this is style where you can customize your color scheme

 <style name="TitleTextStyle" parent="@android:style/TextAppearance.Holo.Widget.ActionBar.Title">
    <item name="android:fontFamily">@string/you_font_family</item>
    <item name="android:textStyle">normal</item>
    <item name="android:textAppearance">@style/you_text_style</item>
    <item name="android:textColor">#000000</item>
    <item name="android:textSize">20sp</item>
</style>

I had already installed pods. Build worked without any problems when I builded application on my device, but archive didn't work. I just run:

pod install

no new pods were installed, just .xcodeproj file got regenerated and archive started working

This error occurred for me because mod_rewrite was not enabled. Everything worked fine after enabling the rewrite module: https://www.debuntu.org/how-to-enable-apache-modules-under-debian-based-system-page-2/

From the Bjarne Stroustrup C++0x FAQ:

__cplusplus

In C++11 the macro __cplusplus will be set to a value that differs from (is greater than) the current 199711L.

Although this isn't as helpful as one would like. gcc (apparently for nearly 10 years) had this value set to 1, ruling out one major compiler, until it was fixed when gcc 4.7.0 came out.

These are the C++ standards and what value you should be able to expect in __cplusplus:

• C++ pre-C++98: __cplusplus is 1.
• C++98: __cplusplus is 199711L.
• C++98 + TR1: This reads as C++98 and there is no way to check that I know of.
• C++11: __cplusplus is 201103L.
• C++14: __cplusplus is 201402L.
• C++17: __cplusplus is 201703L.

If the compiler might be an older gcc, we need to resort to compiler specific hackery (look at a version macro, compare it to a table with implemented features) or use Boost.Config (which provides relevant macros). The advantage of this is that we actually can pick specific features of the new standard, and write a workaround if the feature is missing. This is often preferred over a wholesale solution, as some compilers will claim to implement C++11, but only offer a subset of the features.

The Stdcxx Wiki hosts a comprehensive matrix for compiler support of C++0x features (archive.org link) (if you dare to check for the features yourself).

Unfortunately, more finely-grained checking for features (e.g. individual library functions like std::copy_if) can only be done in the build system of your application (run code with the feature, check if it compiled and produced correct results - autoconf is the tool of choice if taking this route).

#!/bin/bash

current_usage=$( df -h | grep 'gfsvg-gfslv' | awk {'print $5'} )
echo $current_usage
critical_usage=6%
warning_usage=3%

if [[ ${current_usage%?} -lt ${warning_usage%?} ]]; then
echo OK current usage is $current_usage
elif [[ ${current_usage%?} -ge ${warning_usage%?} ]] && [[ ${current_usage%?} -lt ${critical_usage%?} ]]; then
echo Warning $current_usage
else
echo Critical $current_usage
fi

you should change import Header from './src/components/header/header' to

import Header from '../src/components/header/header'

Neither text-align:center nor display:inline-block worked for me on their own, but combining both did:

ul {
  text-align: center;
}
li {
  display: inline-block;
}

WAITFOR DELAY 'HH:MM:SS'

I believe the maximum time this can wait for is 23 hours, 59 minutes and 59 seconds.

Here's a Scalar-valued function to show it's use; the below function will take an integer parameter of seconds, which it then translates into HH:MM:SS and executes it using the EXEC sp_executesql @sqlcode command to query. Below function is for demonstration only, i know it's not fit for purpose really as a scalar-valued function! :-)

    CREATE FUNCTION [dbo].[ufn_DelayFor_MaxTimeIs24Hours]
    (
    @sec int
    )
    RETURNS
    nvarchar(4)
    AS
    BEGIN


    declare @hours int = @sec / 60 / 60
    declare @mins int = (@sec / 60) - (@hours * 60)
    declare @secs int = (@sec - ((@hours * 60) * 60)) - (@mins * 60)


    IF @hours > 23 
    BEGIN
    select @hours = 23
    select @mins = 59
    select @secs = 59
    -- 'maximum wait time is 23 hours, 59 minutes and 59 seconds.'
    END


    declare @sql nvarchar(24) = 'WAITFOR DELAY '+char(39)+cast(@hours as nvarchar(2))+':'+CAST(@mins as nvarchar(2))+':'+CAST(@secs as nvarchar(2))+char(39)


    exec sp_executesql @sql

    return ''
    END

IF you wish to delay longer than 24 hours, I suggest you use a @Days parameter to go for a number of days and wrap the function executable inside a loop... e.g..

    Declare @Days int = 5
    Declare @CurrentDay int = 1

    WHILE @CurrentDay <= @Days
    BEGIN

    --24 hours, function will run for 23 hours, 59 minutes, 59 seconds per run.
    [ufn_DelayFor_MaxTimeIs24Hours] 86400

    SELECT @CurrentDay = @CurrentDay + 1
    END

instanceof can only be used with reference types, not primitive types. isAssignableFrom() can be used with any class objects:

a instanceof int  // syntax error
3 instanceof Foo  // syntax error
int.class.isAssignableFrom(int.class)  // true

See http://java.sun.com/javase/6/docs/api/java/lang/Class.html#isAssignableFrom(java.lang.Class).

My version of @Merak Marey's Code. I am checking if files exist already and different download directories for .txt and other files

        static void DownloadAll()
    {
        string host = "xxx.xxx.xxx.xxx";
        string username = "@@@";
        string password = "123";string remoteDirectory = "/IN/";
        string finalDir = "";
        string localDirectory = @"C:\filesDN\";
        string localDirectoryZip = @"C:\filesDN\ZIP\";
        using (var sftp = new SftpClient(host, username, password))
        {
            Console.WriteLine("Connecting to " + host + " as " + username);
            sftp.Connect();
            Console.WriteLine("Connected!");
            var files = sftp.ListDirectory(remoteDirectory);

            foreach (var file in files)
            {

                string remoteFileName = file.Name;

                if ((!file.Name.StartsWith(".")) && ((file.LastWriteTime.Date == DateTime.Today)))
                { 

                    if (!file.Name.Contains(".TXT"))
                    {
                        finalDir = localDirectoryZip;
                    } 
                    else 
                    {
                        finalDir = localDirectory;
                    }


                    if (File.Exists(finalDir  + file.Name))
                    {
                        Console.WriteLine("File " + file.Name + " Exists");
                    }else{
                        Console.WriteLine("Downloading file: " + file.Name);
                          using (Stream file1 = File.OpenWrite(finalDir + remoteFileName))
                    {
                        sftp.DownloadFile(remoteDirectory + remoteFileName, file1);
                    }
                    }
                }
            }



            Console.ReadLine();

        }

You can simply append string like:

var worldArg = "world is good"

worldArg += " to live";

This is what I have used in the past.

html, body {
  height: 100%;
  overflow: auto;
}

Also in the iframe add the following style

border: 0; position:fixed; top:0; left:0; right:0; bottom:0; width:100%; height:100%

Well one way to do it would be saving the base method and then calling it from the overriden method, like so

MyClass.prototype._do_base = MyClass.prototype.do;
MyClass.prototype.do = function(){  

    if (this.name === 'something'){

        //do something new

    }else{
        return this._do_base();
    }

};

I had installed python3 but my python in /usr/bin/python was still the old 2.7 version

This worked (<pkg> was pyserial in my case):

python3 -m pip install <pkg>

1. Open web.config in the directory where the old pages reside

2. Then add code for the old location path and new destination as follows:

   <configuration>
     <location path="services.htm">
       <system.webServer>
         <httpRedirect enabled="true" destination="http://domain.com/services" httpResponseStatus="Permanent" />
       </system.webServer>
     </location>
     <location path="products.htm">
       <system.webServer>
         <httpRedirect enabled="true" destination="http://domain.com/products" httpResponseStatus="Permanent" />
       </system.webServer>
     </location>
   </configuration>
   

You may add as many location paths as necessary.

The server.contextPath or server.context-path works if

in pom.xml

1. packing should be war not jar

2. Add following dependencies

   <dependency>
       <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
   </dependency>
   <!-- Tomcat/TC server -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-starter-tomcat</artifactId>
       <scope>provided</scope>
    </dependency>
   

   In eclipse, right click on project --> Run as --> Spring Boot App.

In our case we just want to reload the page in webview and for some reasons we couldn't find out why! We try almost every solution that has been on the web, but stuck with no reloading using location.reload() or alternative solutions like window.location.reload(), location.reload(true), ...!

Here is our simple solution :

Just use a < a > tag with the empty "href" attribution value like this :

< a href="" ...>Click Me</a>

(in some cases you have to use "return true" on click of the target to trigger reload)

For more information check out this question : Is an empty href valid?

$("#closeLink").click(closeIt);

Let's say you want to call your function passing some args to it i.e., closeIt(1, false). Then, you should build an anonymous function and call closeIt from it.

$("#closeLink").click(function() {
    closeIt(1, false);
});

Using simple html,

 <div> 
    <object type="text/html" data="http://validator.w3.org/" width="800px" height="600px" style="overflow:auto;border:5px ridge blue">
    </object>
 </div>

Or jquery,

<script>
        $("#mydiv")
            .html('<object data="http://your-website-domain"/>');
</script>

JSFIDDLE DEMO

Here's a function to upscale or downscale an image by desired width or height while maintaining aspect ratio

# Resizes a image and maintains aspect ratio
def maintain_aspect_ratio_resize(image, width=None, height=None, inter=cv2.INTER_AREA):
    # Grab the image size and initialize dimensions
    dim = None
    (h, w) = image.shape[:2]

    # Return original image if no need to resize
    if width is None and height is None:
        return image

    # We are resizing height if width is none
    if width is None:
        # Calculate the ratio of the height and construct the dimensions
        r = height / float(h)
        dim = (int(w * r), height)
    # We are resizing width if height is none
    else:
        # Calculate the ratio of the width and construct the dimensions
        r = width / float(w)
        dim = (width, int(h * r))

    # Return the resized image
    return cv2.resize(image, dim, interpolation=inter)

Usage

import cv2

image = cv2.imread('1.png')
cv2.imshow('width_100', maintain_aspect_ratio_resize(image, width=100))
cv2.imshow('width_300', maintain_aspect_ratio_resize(image, width=300))
cv2.waitKey()

Using this example image

Simply downscale to width=100 (left) or upscale to width=300 (right)

Launch chrome like so to bypass this restriction: open -a "/Applications/Google Chrome.app/Contents/MacOS/Google Chrome" --args --allow-file-access-from-files.

Derived from Josh Lee's comment but I needed to specify the full path to Google Chrome so as to avoid having Google Chrome opening from my Windows partition (in Parallels).

To the delight of font purists everywhere, the iPhone system interface uses Helvetica or a variant thereof.

The original iPhone, iPhone 3G and iPhone 3GS system interface uses Helvetica. As first noted by the always excellent DaringFireball, the iPhone 4 uses a subtly revised font called "Helvetica Neue." DaringFireball also notes that this change is related to the iPhone 4 display rather than the iOS 4 operating system and older iPhone models running iOS 4 still use Helvetica as the system font.

iPod models released prior to the iPhone use either Chicago, Espy Sans, or Myriad and use Helvetica after the release of the iPhone.

From http://www.everyipod.com/iphone-faq/iphone-who-designed-iphone-font-used-iphone-ringtones.html

For iOS9 it has changed to San Fransisco. See http://developer.apple.com/fonts for more info.

In the Node REPL, to get a DB connection that was the value of a promise, I took the following approach:

let connection
try {
  (async () => {
    connection = await returnsAPromiseResolvingToConnection()
  })()
} catch(err) {
  console.log(err)
}

The line with await would normally return a promise. This code can be pasted into the Node REPL or if saved in index.js it can be run in Bash with

node -i -e "$(< index.js)"

which leaves you in the Node REPL after running the script with access to the set variable. To confirm that the asynchronous function has returned, you can log connection for example, and then you're ready to use the variable. One of course wouldn't want to count on the asynchronous function being resolved yet for any code in the script outside the asynchronous function.

In SQLServer Management Studio:

Tools -> Options -> Designers -> Table and Database Designers

• Unselect 'Prevent saving changes that require table re-creation'.

Then:

• right click the table you want to re-order the columns for.
• click 'Design'.
• Drag the columns to the order you want.
• finally, click save.

SQLServer Management studio will drop the table and recreate it using the data.

Sometimes the parent ppid cannot be killed, hence kill the zombie pid

kill -9 $(ps -A -ostat,pid | awk '/[zZ]/{ print $2 }')

Well I know this might be a big change or even not suitable for your project, but did you consider not performing the push until you already have the data? That way you only need to draw the view once and the user experience will also be better - the push will move in already loaded.

The way you do this is in the UITableView didSelectRowAtIndexPath you asynchronously ask for the data. Once you receive the response, you manually perform the segue and pass the data to your viewController in prepareForSegue. Meanwhile you may want to show some activity indicator, for simple loading indicator check https://github.com/jdg/MBProgressHUD

shorter way ....

var a = new Test { Id = 1 , Name = "A" , date = DateTime.Now};
var b = new Test { Id = 1 , Name = "AXXX", date = DateTime.Now };

var compare = string.Join("",a.GetType().GetProperties().Select(x => x.GetValue(a)).ToArray())==
              string.Join("",b.GetType().GetProperties().Select(x => x.GetValue(b)).ToArray());

An approach that generates the values over a range as we iterate, up to a breaking condition, instead of generating first a whole range and then iterating over it, using Iterator, (inspired in @RexKerr use of Stream)

var sum = 0
for ( i <- Iterator.from(1).takeWhile( _ => sum < 1000) ) sum += i

InputStream is = new FileInputStream("c://filename");
return is;

Presuming that you have an array of bits, how about this: 1. Starting from MSB, push bits into a stack one by one. 2. Pop bits from this stack into another array (or the same array if you want to save space), placing the first popped bit into MSB and going on to less significant bits from there.

Stack stack = new Stack();
Bit[] bits = new Bit[] { 0, 0, 1, 0, 0, 0, 0, 0 };

for (int i = 0; i < bits.Length; i++) 
{
    stack.push(bits[i]);
}

for (int i = 0; i < bits.Length; i++)
{
    bits[i] = stack.pop();
}

Without code in iframe + animate:

<script language="javascript" type="text/javascript">

function resizeIframe(obj) {

    jQuery(document).ready(function($) {

        $(obj).animate({height: obj.contentWindow.document.body.scrollHeight + 'px'}, 500)

    });

E.Run runForBreak = new E.Run();

E.Text textForBreak = new E.Text() { Space = SpaceProcessingModeValues.Preserve };
textForBreak.Text = "\n";
runForBreak.Append(textForBreak);
sharedStringItem.Append(runForBreak);

You can get a list of any configured remote URLs with the command git remote -v.

This will give you something like the following:

base    /home/***/htdocs/base (fetch)
base    /home/***/htdocs/base (push)
origin  [email protected]:*** (fetch)
origin  [email protected]:*** (push)

Do while loop will be executed atleast once.......but while loop will check the condition first and then it may or may not get executed depending on the condition.

In your example wdlen may assume any garbage value which is > 2 so while loop will never get executed.

whereas do while loop will be ececuted and will tell u to enter the value and check that value in terminating condition

If you are programming in PHP, it is useful to split lines by \n and then trim() each line (provided you don't care about whitespace) to give you a "clean" line regardless.

foreach($line in explode("\n", $data))
{
    $line = trim($line);
    ...
}

in continuation to @ Cuong Le's answer , my approach to prevent replay attack would be

// Encrypt the Unix Time at Client side using the shared private key(or user's password)

// Send it as part of request header to server(WEB API)

// Decrypt the Unix Time at Server(WEB API) using the shared private key(or user's password)

// Check the time difference between the Client's Unix Time and Server's Unix Time, should not be greater than x sec

// if User ID/Hash Password are correct and the decrypted UnixTime is within x sec of server time then it is a valid request

Quick and dirty way:

<View
    android:id="@+id/colored_bar"
    android:layout_width="48dp"
    android:layout_height="3dp"
    android:background="@color/bar_red" />

Oracle: Get a list of the full datatype in your table:

select data_type || '(' || data_length || ')' 
from user_tab_columns where TABLE_NAME = 'YourTableName'

That is working for me. Could be a browser issue as mentioned, or maybe jQuery isn't registered properly, or perhaps the real issue is more complicated (that you made a simpler version to ask this). PS - did have to click out of the text box to make it fire.

test.matches() method checks all text.use test.find()

This is how I do this in order to work with LINQ.

DateTime date_time_to_compare = DateTime.Now;
//Compare only date parts
context.YourObject.FirstOrDefault(r =>
                EntityFunctions.TruncateTime(r.date) == EntityFunctions.TruncateTime(date_to_compare));

If you only use dtOne.Date == dtTwo.Date it wont work with LINQ (Error: The specified type member 'Date' is not supported in LINQ to Entities)

Swift 2

dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), {
    //All stuff here
})

your string is NOT a valid json to start with.

a valid json will be,

{
    "area": [
        {
            "area": "kothrud"
        },
        {
            "area": "katraj"
        }
    ]
}

if you do a json_decode, it will yield,

stdClass Object
(
    [area] => Array
        (
            [0] => stdClass Object
                (
                    [area] => kothrud
                )

            [1] => stdClass Object
                (
                    [area] => katraj
                )

        )

)

Update: to use

$string = '

{
    "area": [
        {
            "area": "kothrud"
        },
        {
            "area": "katraj"
        }
    ]
}

';
            $area = json_decode($string, true);

            foreach($area['area'] as $i => $v)
            {
                echo $v['area'].'<br/>';
            }

Output:

kothrud
katraj

When TRUE, returned objects will be converted into associative arrays. for more information, click here

In Python, a list is a dynamic array. You can create one like this:

lst = [] # Declares an empty list named lst

Or you can fill it with items:

lst = [1,2,3]

You can add items using "append":

lst.append('a')

You can iterate over elements of the list using the for loop:

for item in lst:
    # Do something with item

Or, if you'd like to keep track of the current index:

for idx, item in enumerate(lst):
    # idx is the current idx, while item is lst[idx]

To remove elements, you can use the del command or the remove function as in:

del lst[0] # Deletes the first item
lst.remove(x) # Removes the first occurence of x in the list

Note, though, that one cannot iterate over the list and modify it at the same time; to do that, you should instead iterate over a slice of the list (which is basically a copy of the list). As in:

 for item in lst[:]: # Notice the [:] which makes a slice
       # Now we can modify lst, since we are iterating over a copy of it

Telerik today released a Beta of their own decompilation tool, JustDecompile. Closed source, but free and looks promising.

In modern-day JS, you can get your JSON data by calling ES6's fetch() on your URL and then using ES7's async/await to "unpack" the Response object from the fetch to get the JSON data like so:

const getJSON = async url => {
  try {
    const response = await fetch(url);
    if(!response.ok) // check if response worked (no 404 errors etc...)
      throw new Error(response.statusText);

    const data = await response.json(); // get JSON from the response
    return data; // returns a promise, which resolves to this data value
  } catch(error) {
    return error;
  }
}

console.log("Fetching data...");
getJSON("https://soundcloud.com/oembed?url=http%3A//soundcloud.com/forss/flickermood&format=json").then(data => {
  console.log(data);
}).catch(error => {
  console.error(error);
});

The above method can be simplified down to a few lines if you ignore the exception/error handling (usually not recommended as this can lead to unwanted errors):

const getJSON = async url => {
  const response = await fetch(url);
  return response.json(); // get JSON from the response 
}

console.log("Fetching data...");
getJSON("https://soundcloud.com/oembed?url=http%3A//soundcloud.com/forss/flickermood&format=json")
  .then(data => console.log(data));

A refactoring-safe, cut&paste-safe solution that avoids the definition of ad-hoc classes below.

Write a static method that recover the class name having care to include the class name in the method name:

private static String getMyClassName(){
  return MyClass.class.getName();
}

then recall it in your static method:

public static void myMethod(){
  Tracer.debug(getMyClassName(), "message");
}

Refactoring safety is given by avoiding the use of strings, cut&paste safety is granted because if you cut&paste the caller method you won't find the getMyClassName() in the target "MyClass2" class, so you will be forced to redefine and update it.

wrappingColumn has been deprecated in favour of wordWrap.

Add this line to settings.json to set wordWrap on by default:

"editor.wordWrap": "on" 

or open user settings:

Mac: ? + ,

Windows: Ctrl + ,

Then search for "wordWrap" or scroll through the 'Commonly Used' settings to find it and select 'on'

Just to add on Jacek's perfect solution. If you're trying to do this in Kotlin, it wont work immediately. Instead, you'll want to use this:

@Throws(IOException::class)
fun getSplashVideo(context: Context): File {
    val cacheFile = File(context.cacheDir, "splash_video")
    try {
        val inputStream = context.assets.open("splash_video")
        val outputStream = FileOutputStream(cacheFile)
        try {
            inputStream.copyTo(outputStream)
        } finally {
            inputStream.close()
            outputStream.close()
        }
    } catch (e: IOException) {
        throw IOException("Could not open splash_video", e)
    }
    return cacheFile
}

In options object you have used "=" sign to assign value to port but we have to use ":" to assign values to properties in object when using object literal to create an object i.e."{}" ,these curly brackets. Even when you use function expression or create an object inside object you have to use ":" sign. for e.g.:

    var rishabh = {
        class:"final year",
        roll:123,
        percent: function(marks1, marks2, marks3){
                      total = marks1 + marks2 + marks3;
                      this.percentage = total/3 }
                    };

john.percent(85,89,95);
console.log(rishabh.percentage);

here we have to use commas "," after each property. but you can use another style to create and initialize an object.

var john = new Object():
john.father = "raja";  //1st way to assign using dot operator
john["mother"] = "rani";// 2nd way to assign using brackets and key must be string

The AAR file consists of a JAR file and some resource files (it is basically a standard zip file with a custom file extension). Here are the steps to convert:

1. Extract the AAR file using standard zip extract (rename it to *.zip to make it easier)
2. Find the classes.jar file in the extracted files
3. Rename it as you like and use that jar file in your project

From Oracle (but works in most SQL DBs):

SELECT LASTNAME, COUNT(*)
FROM STUDENTS
GROUP BY LASTNAME
HAVING COUNT(*) >= 3

P.S. it's faster one, because you have no Select withing Select methods here

After failing with the provided answers in this thread, I stumbled upon this article with the solution.

There are two things not intuitive about setting up the scrollview with autolayout:

1. The constraints you set up as margin between the contentview and scrollview do not influence the size of the contentview. They really are margins. And to make it work, the contentview should have a fixed size.
2. The trick to the fixed size is that you can set the width of the contentview equal to that of the scrollview's parent. Just select both views in the tree on the left and add the equal widths constraint.

This is the gist of that article. For a complete explanation, including illustrations, check it out.

Use the valgrind option --track-origins=yes to have it track the origin of uninitialized values. This will make it slower and take more memory, but can be very helpful if you need to track down the origin of an uninitialized value.

Update: Regarding the point at which the uninitialized value is reported, the valgrind manual states:

It is important to understand that your program can copy around junk (uninitialised) data as much as it likes. Memcheck observes this and keeps track of the data, but does not complain. A complaint is issued only when your program attempts to make use of uninitialised data in a way that might affect your program's externally-visible behaviour.

From the Valgrind FAQ:

As for eager reporting of copies of uninitialised memory values, this has been suggested multiple times. Unfortunately, almost all programs legitimately copy uninitialised memory values around (because compilers pad structs to preserve alignment) and eager checking leads to hundreds of false positives. Therefore Memcheck does not support eager checking at this time.

If you're using a linux server for your application then it is necessary to use lowercase file name and class name to avoid this issue.

Ex.

Filename: csvsample.php

class csvsample {

}

With the power of Kotlin's extension functions, the code can look a lot more elegant. Put this anywhere you want (I have it inside an ExtensionFunctions.kt file):

/**
 * WARNING: This assumes the layout manager is a LinearLayoutManager
 */
fun RecyclerView.addOnScrolledToEnd(onScrolledToEnd: () -> Unit){

    this.addOnScrollListener(object: RecyclerView.OnScrollListener(){

        private val VISIBLE_THRESHOLD = 5

        private var loading = true
        private var previousTotal = 0

        override fun onScrollStateChanged(recyclerView: RecyclerView,
                                          newState: Int) {

            with(layoutManager as LinearLayoutManager){

                val visibleItemCount = childCount
                val totalItemCount = itemCount
                val firstVisibleItem = findFirstVisibleItemPosition()

                if (loading && totalItemCount > previousTotal){

                    loading = false
                    previousTotal = totalItemCount
                }

                if(!loading && (totalItemCount - visibleItemCount) <= (firstVisibleItem + visibleThreshold)){

                    onScrolledToEnd()
                    loading = true
                }
            }
        }
    })
}

And then use it like this:

youRecyclerView.addOnScrolledToEnd {
    //What you want to do once the end is reached
}

This solution is based on Kushal Sharma's answer. However, this is a bit better because:

1. It uses onScrollStateChanged instead of onScroll. This is better because onScroll is called every time there is any sort of movement in the RecyclerView, whereas onScrollStateChanged is only called when the state of the RecyclerView is changed. Using onScrollStateChanged will save you CPU time and, as a consequence, battery.
2. Since this uses Extension Functions, this can be used in any RecyclerView you have. The client code is just 1 line.

Simply rename the folder. git is a "content-tracker", so the SHA1 hashes are the same and git knows, that you rename it. The only thing that changes is the tree-object.

rm <directory>
git add .
git commit

I'd guess that Remove and Substring would tie for first place, since they both slurp up a fixed-size portion of the string, whereas TrimStart does a scan from the left with a test on each character and then has to perform exactly the same work as the other two methods. Seriously, though, this is splitting hairs.

I use this code:

show-hide button

 <a @click.stop="visualSwitch()"> show hide </a>

show-hide element

<div class="dialog-popup" v-if="visualState" @click.stop=""></div>

script

data () { return {
    visualState: false,
}},
methods: {
    visualSwitch() {
        this.visualState = !this.visualState;
        if (this.visualState)
            document.addEventListener('click', this.visualState);
        else
            document.removeEventListener('click', this.visualState);
    },
},

Update: remove watch; add stop propagation

Something like this works for me:

<xsl:choose>
  <xsl:when test="string(number(categoryName)) = 'NaN'"> - </xsl:when> 
  <xsl:otherwise> 
    <xsl:number value="categoryName" />
  </xsl:otherwise>
</xsl:choose>

Or the other way around:

<xsl:choose>
  <xsl:when test="string(number(categoryName)) != 'NaN'">
    <xsl:number value="categoryName" />
  </xsl:when> 
  <xsl:otherwise> - </xsl:otherwise>
</xsl:choose>

Note: If you don't check null values or handle null values, IE7 returns -2147483648 instead of NaN.

UPDATE TableName SET ColumnName= ISNULL(ColumnName, 0 ) WHERE Id = 10

This worked for me just now:

<canvas id="c" height="100" width="100" style="border:1px solid red"></canvas>
<script>
var c = document.getElementById('c');
alert(c.height + ' ' + c.width);
c.height = 200;
c.width = 200;
alert(c.height + ' ' + c.width);
</script>

You can simply use a conditional statement a==b?c:d

For example :

Container(
  color: Colors.white,
  child: ('condition')
  ? Widget1(...)
  : Widget2(...)
)

I hope you got the idea.

Suppose if there is no else condition you can use a SizedBox.shrink()

Container(
      color: Colors.white,
      child: ('condition')
       ? Widget1(...)
       : SizedBox.shrink()
    )

If it is a column no need to write ?: operator

Column(
 children: <Widget>[
  if('condition')
    Widget1(...),
 ],
)

I use join to separate the word in array with "and, or , / , &"

EXAMPLE

HTML

<p>London Mexico Canada</p>
<div></div>

JS

 newText = $("p").text().split(" ").join(" or ");
 $('div').text(newText);

Results

London or Mexico or Canada

One way is to add your shortcut keys to the commands themselves them as InputGestures. Commands are implemented as RoutedCommands.

This enables the shortcut keys to work even if they're not hooked up to any controls. And since menu items understand keyboard gestures, they'll automatically display your shortcut key in the menu items text, if you hook that command up to your menu item.

1. Create static attribute to hold a command (preferably as a property in a static class you create for commands - but for a simple example, just using a static attribute in window.cs):

    public static RoutedCommand MyCommand = new RoutedCommand();
   

2. Add the shortcut key(s) that should invoke method:

    MyCommand.InputGestures.Add(new KeyGesture(Key.S, ModifierKeys.Control));
   

3. Create a command binding that points to your method to call on execute. Put these in the command bindings for the UI element under which it should work for (e.g., the window) and the method:

    <Window.CommandBindings>
        <CommandBinding Command="{x:Static local:MyWindow.MyCommand}" Executed="MyCommandExecuted"/>
    </Window.CommandBindings>
   
    private void MyCommandExecuted(object sender, ExecutedRoutedEventArgs e) { ... }
   

There is a plugin, adampietrasiak/jquery.initialize, which is based on MutationObserver that achieves this simply.

$.initialize(".some-element", function() {
    $(this).css("color", "blue");
});

If you want to replace multiple values in a data frame, looping through all columns might help.

Say you want to replace "" and 100:

na_codes <- c(100, "")
for (i in seq_along(df)) {
    df[[i]][df[[i]] %in% na_codes] <- NA
}

This may not be a popular solution for everyone, but I like the Application Framework in Visual Basic, even when using C#.

Add a reference to Microsoft.VisualBasic

Create a class called WindowsFormsApplication

public class WindowsFormsApplication : WindowsFormsApplicationBase
{

    /// <summary>
    /// Runs the specified mainForm in this application context.
    /// </summary>
    /// <param name="mainForm">Form that is run.</param>
    public virtual void Run(Form mainForm)
    {
        // set up the main form.
        this.MainForm = mainForm;

        // Example code
        ((Form1)mainForm).FileName = this.CommandLineArgs[0];

        // then, run the the main form.
        this.Run(this.CommandLineArgs);
    }

    /// <summary>
    /// Runs this.MainForm in this application context. Converts the command
    /// line arguments correctly for the base this.Run method.
    /// </summary>
    /// <param name="commandLineArgs">Command line collection.</param>
    private void Run(ReadOnlyCollection<string> commandLineArgs)
    {
        // convert the Collection<string> to string[], so that it can be used
        // in the Run method.
        ArrayList list = new ArrayList(commandLineArgs);
        string[] commandLine = (string[])list.ToArray(typeof(string));
        this.Run(commandLine);
    }

}

Modify your Main() routine to look like this

static class Program
{

    [STAThread]
    static void Main()
    {
        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);

        var application = new WindowsFormsApplication();
        application.Run(new Form1());
    }
}

This method offers some additional usefull features (like SplashScreen support and some usefull events)

public event NetworkAvailableEventHandler NetworkAvailabilityChanged;d.
public event ShutdownEventHandler Shutdown;
public event StartupEventHandler Startup;
public event StartupNextInstanceEventHandler StartupNextInstance;
public event UnhandledExceptionEventHandler UnhandledException;

Many times the problem comes because php does not support short open tags in php.ini file, i.e:

<?
   phpinfo();
?>

You must use:

<?php
   phpinfo();
?>

I don't think it can. When a service is "stopped", it gets totally unloaded.

Well, OK, there's always a way I suppose. For instance, you could create a detached process to stop the service, then restart it, then exit.

Because % is only defined for integer types. That's the modulus operator.

5.6.2 of the standard:

The operands of * and / shall have arithmetic or enumeration type; the operands of % shall have integral or enumeration type. [...]

As Oli pointed out, you can use fmod(). Don't forget to include math.h.

Just noting this here in case anyone else has a similar issue.
If you're directing a request directly to a JSP, using Apache Tomcat web.xml configuration, then ${requestScope.attr} doesn't seem to work, instead ${param.attr} contains the request attribute attr.

Store your data in temp table

Select * into tempTable from table1

Now update the column

 UPDATE table1
    SET table1.FileName = (select FileName from tempTable where tempTable.id = table1.ID);

Along with the above answers Try this for min and max length:

In Model

[StringLength(13, MinimumLength=10)]
public string MobileNo { get; set; }

In view

 <div class="col-md-8">
           @Html.TextBoxFor(m => m.MobileNo, new { @class = "form-control" , type="phone"})
           @Html.ValidationMessageFor(m => m.MobileNo,"Invalid Number")
           @Html.CheckBoxFor(m => m.IsAgreeTerms, new {@checked="checked",style="display:none" })

The microsoft telnet.exe is not scriptable without using another script (which needs keyboard focus), as shown in another answer to this question, but there is a free

Telnet Scripting Tool v.1.0 by Albert Yale

that you can google for and which is both scriptable and loggable and can be launched from a batch file without needing keyboard focus.

The problem with telnet.exe and a second script when keyboard focus is being used is that if someone is using the computer at the time the script runs, then it is highly likely that the script will fail due to mouse clicks and keyboard use at that moment in time.

This is simple way to Display Div using:-

$("#musicinfo").show();  //or
$("#musicinfo").css({'display':'block'});  //or
$("#musicinfo").toggle("slow");   //or
$("#musicinfo").fadeToggle();    //or

This is an old question I know, but this is in the top five for several related Google searches. Here's the CSS-only solution without changing the images to background images:

width: auto;
height: auto;
max-width: MaxSize;
max-height: MaxSize;

"MaxSize" is a placeholder for whatever max-width and max-height you want to use, in pixels or percentage. auto will increase (or decrease) the width and height to occupy the space you specify with MaxSize. It will override any defaults for images you or the viewer's browser might have for images. I've found it's especially important on Android's Firefox. Pixels or percentages work for max size. With both the height and width set to auto, the aspect ratio of the original image will be retained.

If you want to fill the space entirely and don't mind the image being larger than its original size, change the two max-widths to min-width: 100% - this will make them completely occupy their space and maintain aspect ratio. You can see an example of this with a Twitter profile's background image.

You can use the asXML method

echo $xml->asXML();

You can also give it a filename

$xml->asXML('filename.xml');

I will soon released a new version of my app to support to galaxy ace.

You can download here: https://play.google.com/store/apps/details?id=droid.pr.coolflashlightfree

In order to solve your problem you should do this:

this._camera = Camera.open();     
this._camera.startPreview();
this._camera.autoFocus(new AutoFocusCallback() {
public void onAutoFocus(boolean success, Camera camera) {
}
});

Parameters params = this._camera.getParameters();
params.setFlashMode(Parameters.FLASH_MODE_ON);
this._camera.setParameters(params);

params = this._camera.getParameters();
params.setFlashMode(Parameters.FLASH_MODE_OFF);
this._camera.setParameters(params);

don't worry about FLASH_MODE_OFF because this will keep the light on, strange but it's true

to turn off the led just release the camera

The same thing happened to me. Here is what I did in order to get it successfully installed. I downloaded KB2999226 update from Microsofts website here: https://www.microsoft.com/en-us/download/details.aspx?id=49093

After installing this package, I started the installation process again. That worked for me.

When console.log(this.ev) is executed after this.fetchEvent();, this doesn't mean the fetchEvent() call is done, this only means that it is scheduled. When console.log(this.ev) is executed, the call to the server is not even made and of course has not yet returned a value.

Change fetchEvent() to return a Promise

     fetchEvent(){
        return  this._apiService.get.event(this.eventId).then(event => {
            this.ev = event;
            console.log(event); // Has a value
            console.log(this.ev); // Has a value
        });
     }

change ngOnInit() to wait for the Promise to complete

    ngOnInit() {
        this.fetchEvent().then(() =>
        console.log(this.ev)); // Now has value;
    }

This actually won't buy you much for your use case.

My suggestion: Wrap your entire template in an <div *ngIf="isDataAvailable"> (template content) </div>

and in ngOnInit()

    isDataAvailable:boolean = false;

    ngOnInit() {
        this.fetchEvent().then(() =>
        this.isDataAvailable = true); // Now has value;
    }

I was also getting the same issue I tried multiple IPs like my public IP and localhost default IP 127.0.0.1 in windows and default gateway but same response. but I forget to check by

C:> ipconfig

ipconfig cleanly say what is my actual IP address of that adapter with which I have connected like I was connected with Wifi adapter my IP address will show me as:

Wireless LAN adapter Wireless Network Connection:

   Connection-specific DNS Suffix  . :
   Link-local IPv6 Address . . . . . : fe80::69fa:9475:431e:fad7%11
   IPv4 Address. . . . . . . . . . . : 192.168.15.92

I hope this will help you.

Pillow is released with installation wheels on Windows:

We provide Pillow binaries for Windows compiled for the matrix of supported Pythons in both 32 and 64-bit versions in wheel, egg, and executable installers. These binaries have all of the optional libraries included

https://pillow.readthedocs.io/en/3.3.x/installation.html#basic-installation

Update: Python 3.6 is now supported by Pillow. Install with pip install pillow and check https://pillow.readthedocs.io/en/latest/installation.html for more information.

However, Python 3.6 is still in alpha and not officially supported yet, although the tests do all pass for the nightly Python builds (currently 3.6a4).

Failing that, downgrade to Python 3.5 or wait until 3.6 is supported by Pillow, probably closer to the 3.6's official release.

The following snippet shows a way to ensure the awaited method completes before returning to the caller. HOWEVER, I wouldn't say it's good practice. Please edit my answer with explanations if you think otherwise.

public async Task AnAsyncMethodThatCompletes()
{
    await SomeAsyncMethod();
    DoSomeMoreStuff();
    await Task.Factory.StartNew(() => { }); // <-- This line here, at the end
}

await AnAsyncMethodThatCompletes();
Console.WriteLine("AnAsyncMethodThatCompletes() completed.")

Instead of setting a limit on length I would propose the following, which has worked for me.

Inside:

config/database.php

replace this line for mysql:

'engine' => 'InnoDB ROW_FORMAT=DYNAMIC',

with:

'engine' => null,

this will also work, if you like

 xcopy  C:\Test\Log "c:\Test\Backup-%date:~4,2%-%date:~7,2%-%date:~10,4%_%time:~0,2%%time:~3,2%" /s /i
 del C:\Test\Log

Although I agree with @assylias that using @BeforeClass is a classic solution it is not always convenient. The method annotated with @BeforeClass must be static. It is very inconvenient for some tests that need instance of test case. For example Spring based tests that use @Autowired to work with services defined in spring context.

In this case I personally use regular setUp() method annotated with @Before annotation and manage my custom static(!) boolean flag:

private static boolean setUpIsDone = false;
.....
@Before
public void setUp() {
    if (setUpIsDone) {
        return;
    }
    // do the setup
    setUpIsDone = true;
}

Hmm. By default, <label> is display: inline; and <input> is (roughly, at least) display: inline-block;, so they should both be on the same line. See http://jsfiddle.net/BJU4f/

Perhaps a stylesheet is setting label or input to display: block?

There's a few ways, the most prominent being getting form data, or getting the query string. Here's one method using JavaScript. When you click on a link it will call the _vals('mytarget', 'theval') which will submit the form data. When your page posts back you can check if this form data has been set and then retrieve it from the form values.

<script language="javascript" type="text/javascript">
 function _vals(target, value){
   form1.all("target").value=target;
   form1.all("value").value=value;
   form1.submit();
 }
</script>

Alternatively you can get it via the query string. PHP has your _GET and _SET global functions to achieve this making it much easier.

I'm sure there's probably more methods which are better, but these are just a few that spring to mind.

EDIT: Building on this from what others have said using the above method you would have an anchor tag like

<a onclick="_vals('name', 'val')" href="#">My Link</a>

And then in your PHP you can get form data using

$val = $_POST['value'];

So when you click on the link which uses JavaScript it will post form data and when the page posts back from this click you can then retrieve it from the PHP.

I know that due to this ugly anonymous inner class usage of TransactionTemplate doesn't look nice, but when for some reason we want to have a test method transactional IMHO it is the most flexible option.

In some cases (it depends on the application type) the best way to use transactions in Spring tests is a turned-off @Transactional on the test methods. Why? Because @Transactional may leads to many false-positive tests. You may look at this sample article to find out details. In such cases TransactionTemplate can be perfect for controlling transaction boundries when we want that control.

As people say, JavaScript will convert a string of number to integer, so it is not possible to use directly on an associative array, but objects will work for you in similar way I think.

You can create your object:

var object = {};

And add the values as array works:

object[1] = value;
object[2] = value;

This will give you:

{
  '1': value,
  '2': value
}

After that you can access it like an array in other languages getting the key:

for(key in object)
{
   value = object[key] ;
}

I have tested and works.

Using jQuery you can do exactly the same thing, for example:

$("a").click();

Which will "click" all anchors on the page.

I needed to convert some double to currency values and found that most of the solutions were OK, but not for me.

The DecimalFormat was eventually the way for me, so here is what I've done:

   public String foo(double value) //Got here 6.743240136E7 or something..
    {
        DecimalFormat formatter;

        if(value - (int)value > 0.0)
            formatter = new DecimalFormat("0.00"); // Here you can also deal with rounding if you wish..
        else
            formatter = new DecimalFormat("0");

        return formatter.format(value);
    }

As you can see, if the number is natural I get - say - 20000000 instead of 2E7 (etc.) - without any decimal point.

And if it's decimal, I get only two decimal digits.

I strongly recommend the method extract the column 'Pollutants':

df_pollutants = pd.DataFrame(df['Pollutants'].values.tolist(), index=df.index)

it's much faster than

df_pollutants = df['Pollutants'].apply(pd.Series)

when the size of df is giant.
