I also have the same problem, and the solution is I didn't bind the event in my onClick. so when it renders for the first time and the data is more, which ends up calling the state setter again, which triggers React to call your function again and so on.

export default function Component(props) {

function clickEvent (event, variable){
    console.log(variable);
}

return (
    <div>
        <IconButton
            key="close"
            aria-label="Close"
            color="inherit"
            onClick={e => clickEvent(e, 10)} // or you can call like this:onClick={() => clickEvent(10)} 
        >
    </div>
)
}

Enable Multidex through build.gradle of your app module

multiDexEnabled true

Same as below -

android {
    compileSdkVersion 27
    defaultConfig {
        applicationId "com.xx.xxx"
        minSdkVersion 15
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"
        multiDexEnabled true //Add this
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            shrinkResources true
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}

Then follow below steps -

1. From the Build menu -> press the Clean Project button.
2. When task completed, press the Rebuild Project button from the Build menu.
3. From menu File -> Invalidate cashes / Restart

compile is now deprecated so it's better to use implementation or api

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 stucked for two days and finally found my solution. I changed the compileSdkVersion to 27 (same with buildToolsVersion)

compileSdkVersion 27
buildToolsVersion '27.0.3'

1)check the package name is the same in google-services.json file

2)make sure that no other project exist with same package name

3)make sure that there is internet access

4)try syncing project and running it again

If you are applying any plugins. Then, in your module Gradle file (usually the app/build.gradle),make sure you add the apply plugin line at the bottom of the file to enable the Gradle plugin.

e.g.

I also faced the same issue. But I forgot to add google-services.json in my project. You can get this file from Google.

Due to updates and changes overtime, version compatibility start causing issues with configuration.

Your webpack.config.js should be like this you can also configure how ever you dim fit.

var path = require('path');
var webpack = require("webpack");

module.exports = {
  entry: './src/js/app.js',
  devtool: 'source-map',
    mode: 'development',
  module: {
    rules: [{
      test: /\.js$/,
      exclude: /node_modules/,
      use: ["babel-loader"]
    },{
      test: /\.css$/,
      use: ['style-loader', 'css-loader']
    }]
  },
  output: {
    path: path.resolve(__dirname, './src/vendor'),
    filename: 'bundle.min.js'
  }
};

Another Thing to notice it's the change of args, you should read babel documentation https://babeljs.io/docs/en/presets

.babelrc

{
    "presets": ["@babel/preset-env", "@babel/preset-react"]
}

NB: you have to make sure you have the above @babel/preset-env & @babel/preset-react installed in your package.json dependencies

I managed to fix it finally. The problem is not related to HikariCP. The problem persisted because of some complex methods in REST controllers executing multiple changes in DB through JPA repositories. For some reasons calls to these interfaces resulted in a growing number of "freezed" active connections, exhausting the pool. Either annotating these methods as @Transactional or enveloping all the logic in a single call to transactional service method seem to solve the problem.

To solve this problem you should use drawable -> new -> image asset and then add your images. You will then find the mipmap folder contains your images, and you can use it by @mibmab/img.

Have you enabled multidexing?. Do extend your main Application class with MultiDexApplication. I have got additional exception mesage before the error. They are as follows.

Uncaught translation error: java.util.concurrent.ExecutionException: java.lang.OutOfMemoryError: GC overhead limit exceeded

Uncaught translation error: java.util.concurrent.ExecutionException: java.lang.OutOfMemoryError: Java heap space
2 errors; aborting

This clearly tells that the error occurred due to out of memory. Try the following:

1. extend your main Application class with MultiDexApplication.
2. close unused applications from background and restart Android Studio.

This will do the trick ;)

Check this has everything you need

http://www.html5rocks.com/en/mobile/fullscreen/

The Chrome team has recently implemented a feature that tells the browser to launch the page fullscreen when the user has added it to the home screen. It is similar to the iOS Safari model.

<meta name="mobile-web-app-capable" content="yes">

I had the same problem. Get the ToolBar and then set Navigation icon

final android.support.v7.widget.Toolbar toolbar = (android.support.v7.widget.Toolbar) findViewById(R.id.toolbar);
toolbar.setNavigationIcon(R.drawable.blablabla);

The error is:

Can not deserialize instance of java.lang.String out of START_ARRAY token at [Source: line: 1, column: 1095] (through reference chain: JsonGen["platforms"])

In JSON, platforms look like this:

"platforms": [
    {
        "platform": "iphone"
    },
    {
        "platform": "ipad"
    },
    {
        "platform": "android_phone"
    },
    {
        "platform": "android_tablet"
    }
]

So try change your pojo to something like this:

private List platforms;

public List getPlatforms(){
    return this.platforms;
}

public void setPlatforms(List platforms){
    this.platforms = platforms;
}

EDIT: you will need change mobile_networks too. Will look like this:

private List mobile_networks;

public List getMobile_networks() {
    return mobile_networks;
}

public void setMobile_networks(List mobile_networks) {
    this.mobile_networks = mobile_networks;
}

 public static class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {

    FrameLayout root;


    public ViewHolder(View itemView) {
        super(itemView);

        root = (FrameLayout) itemView.findViewById(R.id.root);
        root.setOnClickListener(this);
    }


    @Override
    public void onClick(View v) {
        LogUtils.errorLog("POS_CLICKED: ",""+getAdapterPosition());
    }
}

I don't think desc takes an na.rm argument... I'm actually surprised it doesn't throw an error when you give it one. If you just want to remove NAs, use na.omit (base) or tidyr::drop_na:

outcome.df %>%
  na.omit() %>%
  group_by(Hospital, State) %>%
  arrange(desc(HeartAttackDeath)) %>%
  head()

library(tidyr)
outcome.df %>%
  drop_na() %>%
  group_by(Hospital, State) %>%
  arrange(desc(HeartAttackDeath)) %>%
  head()

If you only want to remove NAs from the HeartAttackDeath column, filter with is.na, or use tidyr::drop_na:

outcome.df %>%
  filter(!is.na(HeartAttackDeath)) %>%
  group_by(Hospital, State) %>%
  arrange(desc(HeartAttackDeath)) %>%
  head()

outcome.df %>%
  drop_na(HeartAttackDeath) %>%
  group_by(Hospital, State) %>%
  arrange(desc(HeartAttackDeath)) %>%
  head()

As pointed out at the dupe, complete.cases can also be used, but it's a bit trickier to put in a chain because it takes a data frame as an argument but returns an index vector. So you could use it like this:

outcome.df %>%
  filter(complete.cases(.)) %>%
  group_by(Hospital, State) %>%
  arrange(desc(HeartAttackDeath)) %>%
  head()

Another edge-case EF Core scenario.

Check you have a Migrations/YOURNAMEContextModelSnapshot.cs file.

as detailed in - https://docs.microsoft.com/en-us/ef/core/managing-schemas/migrations/#create-a-migration

If you have tried to manually re-create your database by deleting migration.cs files, be careful that your Migrations/*ContextModelSnapshot.cs file still exists.

Without it, your subsequent migrations have no snapshot on which to create the required differences and your new migrations files will look like they are re-creating everything again from scratch, you will then get the existing table error as above.

This is what I came up with:

  $(document).ready(function(){_x000D_
  _x000D_
  $(".fc-event").each(function(){_x000D_
  _x000D_
   console.log(this.attributes['data'].nodeValue) _x000D_
  });_x000D_
    _x000D_
    });

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>_x000D_
<div id='external-events'>_x000D_
   <h4>Booking</h4>_x000D_
   <div class='fc-event' data='00:30:00' >30 Mins</div>_x000D_
   <div class='fc-event' data='00:45:00' >45 Mins</div>_x000D_
</div>

For me, I changed C:\apps\Java\jdk1.8_162\bin\javac.exe to C:\apps\Java\jdk1.8_162\bin\javacpl.exe Since there was no executable with that name in the bin folder. That worked.

ORDER BY column OFFSET 0 ROWS

Surprisingly makes it work, what a strange feature.

A bigger example with a CTE as a way to temporarily "store" a long query to re-order it later:

;WITH cte AS (
    SELECT .....long select statement here....
)

SELECT * FROM 
(
    SELECT * FROM 
    ( -- necessary to nest selects for union to work with where & order clauses
        SELECT * FROM cte WHERE cte.MainCol= 1 ORDER BY cte.ColX asc OFFSET 0 ROWS 
    ) first
    UNION ALL
    SELECT * FROM 
    (  
        SELECT * FROM cte WHERE cte.MainCol = 0 ORDER BY cte.ColY desc OFFSET 0 ROWS 
    ) last
) as unionized
ORDER BY unionized.MainCol desc -- all rows ordered by this one
OFFSET @pPageSize * @pPageOffset ROWS -- params from stored procedure for pagination, not relevant to example
FETCH FIRST @pPageSize ROWS ONLY -- params from stored procedure for pagination, not relevant to example

So we get all results ordered by MainCol

But the results with MainCol = 1 get ordered by ColX

And the results with MainCol = 0 get ordered by ColY

On most installs you can find it here:

/etc/php.ini

Select
      A.maskid
    , A.maskname
    , A.schoolid
    , B.schoolname
    , STUFF((
          SELECT ',' + T.maskdetail
          FROM dbo.maskdetails T
          WHERE A.maskid = T.maskid
          FOR XML PATH('')), 1, 1, '') as maskdetail 
FROM dbo.tblmask A
JOIN dbo.school B ON B.ID = A.schoolid
Group by  A.maskid
    , A.maskname
    , A.schoolid
    , B.schoolname

mysqli_error()

As in:

$sql = "Your SQL statement here";
$result = mysqli_query($conn, $sql) or trigger_error("Query Failed! SQL: $sql - Error: ".mysqli_error($conn), E_USER_ERROR);

Trigger error is better than die because you can use it for development AND production, it's the permanent solution.

I faced the same problem when connecting to EC2, the issue was with Security Group, I solved by adding the allowed IPs at port 5432

jQuery syntax mentioned above by Danilo Valente is not working. It should be as following-

$.extend(myFunction,{
    bookName:'mybook',
    bookdesc: 'new'
});

Just a little addition to the answer of @dAm2k :

In addition to sudo apt-get remove --purge mysql\*

I've done a sudo apt-get remove --purge mariadb\*.

I seems that in the new release of debian (stretch), when you install mysql it install mariadb package with it.

Hope it helps.

If you are using a mac and sublime text 3, this is what you do.

Go to your /Packages/User/ and create a file called Python.sublime-settings.

Typically /Packages/User is inside your ~/Library/Application Support/Sublime Text 3/Packages/User/Python.sublime-settings if you are using mac os x.

Then you put this in the Python.sublime-settings.

{
    "tab_size": 4,
    "translate_tabs_to_spaces": false
}

Credit goes to Mark Byer's answer, sublime text 3 docs and python style guide.

This answer is mostly for readers who had the same issue and stumble upon this and are using sublime text 3 on Mac OS X.

Your /home/gnu/bin/c++ seem to require additional flag to link things properly and CMake doesn't know about that.

To use /usr/bin/c++ as your compiler run cmake with -DCMAKE_CXX_COMPILER=/usr/bin/c++.

Also, CMAKE_PREFIX_PATH variable sets destination dir where your project' files should be installed. It has nothing to do with CMake installation prefix and CMake itself already know this.

I recommend WinDirStat.

I frequently use WinDirStat to create screen shots for user documentation of open folders and their contents.

It even uses the correct icons for Windows registered file types.

All I would say is missing is an option to display the files without their icons. I can live without it personally, since I am usually pasting the image into a paint program or Visio to edit it, but it would still be a useful feature.

Make sure to create a static DataTable object and then use the following code:

protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
    dt.Rows.RemoveAt(e.RowIndex); 
    GridView1.DataSource = dt;
    GridView1.DataBind();
}

I know it is an old post, but here is another simple solution that is fast.

Public Function worksheetExists(ByVal wb As Workbook, ByVal sheetNameStr As String) As Boolean

On Error Resume Next
worksheetExists = (wb.Worksheets(sheetNameStr).Name <> "")
Err.Clear: On Error GoTo 0

If you have separate layout files for portrait and landscape modes and are getting an inflation error whenever you change orientation after clicking an item, there is most likely a discrepancy between your layout files.

When you get the error, is it only when you click the item in landscape mode or only in portrait mode or both? Does your TaskDetailsFragment activity use a layout file that could have discrepancies between landscape and portrait modes?

 public class State
        {
            public int SID { get; set; }
            public string SName { get; set; }
            public string SCode { get; set; }
            public string SAbbrevation { get; set; }
        }

        public class Country
        {
            public int CID { get; set; }
            public string CName { get; set; }
            public string CAbbrevation { get; set; }
        }


 List<State> states = new List<State>()
            {
               new  State{  SID=1,SName="Telangana",SCode="+91",SAbbrevation="TG"},
               new  State{  SID=2,SName="Texas",SCode="512",SAbbrevation="TS"},
            };

            List<Country> coutries = new List<Country>()
            {
               new Country{CID=1,CName="India",CAbbrevation="IND"},
               new Country{CID=2,CName="US of America",CAbbrevation="USA"},
            };

            var res = coutries.Join(states, a => a.CID, b => b.SID, (a, b) => new {a.CName,b.SName}).ToList();

Usually I handle my operations within a transaction. As I've experienced, it is not enough to set the context command timeout, but the transaction needs a constructor with a timeout parameter. I had to set both time out values for it to work properly.

int? prevto = uow.Context.Database.CommandTimeout;
uow.Context.Database.CommandTimeout = 900;
using (TransactionScope scope = new TransactionScope(TransactionScopeOption.Required, TimeSpan.FromSeconds(900))) {
...
}

At the end of the function I set back the command timeout to the previous value in prevto.

Using EF6

The request body is available as byte stream by HttpServletRequest#getInputStream():

InputStream body = request.getInputStream();
// ...

Or as character stream by HttpServletRequest#getReader():

Reader body = request.getReader();
// ...

Note that you can read it only once. The client ain't going to resend the same request multiple times. Calling getParameter() and so on will implicitly also read it. If you need to break down parameters later on, you've got to store the body somewhere and process yourself.

You can do something like:

s = np.random.normal(2, 3, 1000)
import matplotlib.pyplot as plt
count, bins, ignored = plt.hist(s, 30, density=True)
plt.plot(bins, 1/(3 * np.sqrt(2 * np.pi)) * np.exp( - (bins - 2)**2 / (2 * 3**2) ), 
linewidth=2, color='r')
plt.show()

The default generator for Windows seems to be set to NMAKE. Try to use:

cmake -G "MinGW Makefiles"

Or use the GUI, and select MinGW Makefiles when prompted for a generator. Don't forget to cleanup the directory where you tried to run CMake, or delete the cache in the GUI. Otherwise, it will try again with NMAKE.

Use import javax.persistence.Entity; Instead of import org.hibernate.annotations.Entity;

What problem are you having, specifically?

You can also use the Termial view to ssh/telnet to your local machine. Doesn't have that funny input box for commands.

in the folder where the build.xml resides run command only -

ant

and not the command - `

. if you are using the ant file as build xml then the below steps helps you Steps : open cmd Prompt >> switch to the project location >>type ant and click enter key

Try gcc -c -I/home/me/development/skia sample.c.

I have created a small library of category methods, called Linq to ObjectiveC, that makes this sort of thing more easy. Using the sort method with a key selector, you can sort by birthDate as follows:

NSArray* sortedByBirthDate = [input sort:^id(id person) {
    return [person birthDate];
}]

Was asked here before: Unix command to find lines common in two files

You could also try with perl (credit goes here)

perl -ne 'print if ($seen{$_} .= @ARGV) =~ /10$/'  file1 file2

Emacs would be better if it had a text editor in it... :-)

The prompt you're getting doesn't look like Subversion asking you for a password, it looks like ssh asking for a password. So my guess is that you have checked out an svn+ssh:// checkout, not an svn:// or http:// or https:// checkout.

IIRC all the options you're trying only work for the svn/http/https checkouts. Can you run svn info to confirm what kind of repository you are using ?

If you are using ssh, you should set up key-based authentication so that your scripts will work without prompting for a password.

While the accepted answer is absolutely correct, I would like to provide an additional method.

I ended up here after doing my own searching for a solution to a similar question. I am building a plugin driven framework, and as part of it I wanted people to be able to add menu items to the applications menu to a generic list without exposing an actual Menu object because the framework may deploy on other platforms that don't have Menu UI objects. Adding general info about the menu is easy enough, but allowing the plugin developer enough liberty to create the callback for when the menu is clicked was proving to be a pain. Until it dawned on me that I was trying to re-invent the wheel and normal menus call and trigger the callback from events!

So the solution, as simple as it sounds once you realize it, eluded me until now.

Just create separate classes for each of your current methods, inherited from a base if you must, and just add an event handler to each.

Check the schemes menu at the top of the Xcode project window. Look at the destination you're trying to run in. If you run in the simulator, you don't need to sign your project.

If you run in a device, you need to attach the actual device. It must not say "generic device".

you can use a combination of font-size and line-height to force it to go larger, but obviously only in the situations where you need the font larger too

edit:

Example -> http://www.bse.co.nz EDIT: (this link is no longer relevant)

the select next to the big search box has the following css rules:

#navigation #search .locationDrop {
    font-size:2em;
    line-height:27px;
    display:block;
    float:left;
    height:27px;
    width:200px;
}

The following solution will work with sql server 2005 and above. You can use output to get the required field. inplace of id you can write your key that you want to return. do it like this

FOR SQL SERVER 2005 and above

    using(SqlCommand cmd=new SqlCommand("INSERT INTO Mem_Basic(Mem_Na,Mem_Occ) output INSERTED.ID VALUES(@na,@occ)",con))
    {
        cmd.Parameters.AddWithValue("@na", Mem_NA);
        cmd.Parameters.AddWithValue("@occ", Mem_Occ);
        con.Open();

        int modified =(int)cmd.ExecuteScalar();

        if (con.State == System.Data.ConnectionState.Open) 
            con.Close();

        return modified;
    }
}

FOR previous versions

    using(SqlCommand cmd=new SqlCommand("INSERT INTO Mem_Basic(Mem_Na,Mem_Occ)  VALUES(@na,@occ);SELECT SCOPE_IDENTITY();",con))
    {
        cmd.Parameters.AddWithValue("@na", Mem_NA);
        cmd.Parameters.AddWithValue("@occ", Mem_Occ);
        con.Open();

        int modified = Convert.ToInt32(cmd.ExecuteScalar());

        if (con.State == System.Data.ConnectionState.Open) con.Close();
            return modified;
    }
}

Boost Preprocessor actually has this as of Boost 1.49, as BOOST_PP_VARIADIC_SIZE(...). It works up to size 64.

Under the hood, it's basically the same as Kornel Kisielewicz's answer.

You're looking for any class that implements the Queue interface, excluding PriorityQueue and PriorityBlockingQueue, which do not use a FIFO algorithm.

Probably a LinkedList using add (adds one to the end) and removeFirst (removes one from the front and returns it) is the easiest one to use.

For example, here's a program that uses a LinkedList to queue and retrieve the digits of PI:

import java.util.LinkedList;

class Test {
    public static void main(String args[]) {
        char arr[] = {3,1,4,1,5,9,2,6,5,3,5,8,9};
        LinkedList<Integer> fifo = new LinkedList<Integer>();

        for (int i = 0; i < arr.length; i++)
            fifo.add (new Integer (arr[i]));

        System.out.print (fifo.removeFirst() + ".");
        while (! fifo.isEmpty())
            System.out.print (fifo.removeFirst());
        System.out.println();
    }
} 

Alternatively, if you know you only want to treat it as a queue (without the extra features of a linked list), you can just use the Queue interface itself:

import java.util.LinkedList;
import java.util.Queue;

class Test {
    public static void main(String args[]) {
        char arr[] = {3,1,4,1,5,9,2,6,5,3,5,8,9};
        Queue<Integer> fifo = new LinkedList<Integer>();

        for (int i = 0; i < arr.length; i++)
            fifo.add (new Integer (arr[i]));

        System.out.print (fifo.remove() + ".");
        while (! fifo.isEmpty())
            System.out.print (fifo.remove());
        System.out.println();
    }
}

This has the advantage of allowing you to replace the underlying concrete class with any class that provides the Queue interface, without having to change the code too much.

The basic changes are to change the type of fifo to a Queue and to use remove() instead of removeFirst(), the latter being unavailable for the Queue interface.

Calling isEmpty() is still okay since that belongs to the Collection interface of which Queue is a derivative.

Try to reinstall it with the following code:

categories_posts and categories_news start with substring 'categories_' then it is enough to check that developer_configurations_cms.cfg_name_unique starts with 'categories' instead of check if it contains the given substring. Translating all that into a query:

SELECT *
    FROM developer_configurations_cms

    WHERE developer_configurations_cms.cat_id = '1'
    AND developer_configurations_cms.cfg_variables LIKE '%parent_id=2%'
    AND developer_configurations_cms.cfg_name_unique NOT LIKE 'categories%'

In SQL Server Management Studio you can right click on the database you want to replicate, and select "Script Database as" to have the tool create the appropriate SQL file to replicate that database on another server. You can repeat this process for each table you want to create, and then merge the files into a single SQL file. Don't forget to add a using statement after you create your Database but prior to any table creation.

In more recent versions of SQL Server you can get this in one file in SSMS.

1. Right click a database.
2. Tasks
3. Generate Scripts

This will launch a wizard where you can script the entire database or just portions. There does not appear to be a T-SQL way of doing this.

Well, its not compulsory to restart the emulator you can also reset adb from eclipse itself.

1.) Go to DDMS and there is a reset adb option, please see the image below.

2.) You can restart adb manually from command prompt

  run->cmd->your_android_sdk_path->platform-tools>

Then write the below commands.

adb kill-server - To kill the server forcefully

adb start-server - To start the server

UPDATED:

F:\android-sdk-windows latest\platform-tools>adb kill-server

F:\android-sdk-windows latest\platform-tools>adb start-server
* daemon not running. starting it now on port 5037 *
* daemon started successfully *

you can run plain cat without any arguments as mentioned by bro @Sa'ad to simply keep the container working [actually doing nothing but waiting for user input] (Jenkins' Docker plugin does the same thing)

Just add a data attribute

data-html="true"

and you're good to go.

Eg. usage:

<i data-html="true" class="tooltip ficon-help-icon" twipsy-content-set="true" data-original-title= "<b>Hello</b> Stackoverflow" </i>

It has worked in majority of the tooltip plugins i have tried as of now.

The following program calculates nCr in an efficient manner (compared to calculating factorials etc.)

import operator as op
from functools import reduce

def ncr(n, r):
    r = min(r, n-r)
    numer = reduce(op.mul, range(n, n-r, -1), 1)
    denom = reduce(op.mul, range(1, r+1), 1)
    return numer // denom  # or / in Python 2

As of Python 3.8, binomial coefficients are available in the standard library as math.comb:

>>> from math import comb
>>> comb(10,3)
120

You need to ensure your environment is properly setup in Eclipse so it knows the paths to your includes. Otherwise, it underlines them as not found.

The expression *src refers to the first character in the string, not the whole string. To reassign src to point to a different string tgt, use src = tgt;.

For generating the patches from the topmost commits from a specific sha1 hash:

git format-patch -<n> <SHA1>

The last 10 patches from head in a single patch file:

git format-patch -10 HEAD --stdout > 0001-last-10-commits.patch

I am quite late answering this question (5 years to be exact) but I hope this helps someone.

I suspect that this error is because of the environment variables instead of GCC. When you set a new environment variable you need to open a new Command Prompt! This is the issue 90% of the time (when I first downloaded GCC I was stuck with this for 3 hours!) If this isn't the case, you probably haven't set the environment variables properly or you are in a folder with spaces in the name.

Once you have GCC working, it can be a hassle to compile and delete every time. If you don't want to install a full ide and already have python installed, try this github project: https://github.com/sophiadm/notepad-is-effort It is a small IDE written with tkinter in python. You can just copy the source code and save it as a .py file

Have you tried getFilesDir().getAbsolutePath()?

Seems you fixed your problem by initializing the File object with a full path. I believe this would also do the trick.

We facing this issue today and we solved it. what we do ?

leaflet map load div is below.

<div id="map_container">
   <div id="listing_map" class="right_listing"></div>
</div>

When form input change or submit we follow this step below. after leaflet map container removed in my page and create new again.

$( '#map_container' ).html( ' ' ).append( '<div id="listing_map" class="right_listing"></div>' );

After this code my leaflet map is working fine with form filter to reload again.

Thank you.

in your terminal, navigate to home directory

cd

create file .bash_profile

touch .bash_profile

open file with TextEdit

open -e .bash_profile

insert line into TextEdit

save file and reload file

source ~/.bash_profile

check if adb was set into path

adb version

One liner version

Echo your export command and redirect the output to be appended to .bash_profile file and restart terminal. (have not verified this but should work)

echo "export PATH=$PATH:/Users/username/Library/Android/sdk/platform-tools/ sdk/platform-tools/" >> ~/.bash_profile

Both ways are viable, but they do different things when it comes to inheritance with an overridden static method. Choose the one whose behavior you expect:

class Super {
  static whoami() {
    return "Super";
  }
  lognameA() {
    console.log(Super.whoami());
  }
  lognameB() {
    console.log(this.constructor.whoami());
  }
}
class Sub extends Super {
  static whoami() {
    return "Sub";
  }
}
new Sub().lognameA(); // Super
new Sub().lognameB(); // Sub

Referring to the static property via the class will be actually static and constantly give the same value. Using this.constructor instead will use dynamic dispatch and refer to the class of the current instance, where the static property might have the inherited value but could also be overridden.

This matches the behavior of Python, where you can choose to refer to static properties either via the class name or the instance self.

If you expect static properties not to be overridden (and always refer to the one of the current class), like in Java, use the explicit reference.

Have a look at the article Visual Studio Installer Deployment. It will surely help you.

You can choose the correct version of .NET framework on the page. So for you, make it .NET 4.5. I guess that would be there for Visual Studio 2012.

1. RestTemplate timeout with SimpleClientHttpRequestFactory To programmatically override the timeout properties, we can customize the SimpleClientHttpRequestFactory class as below.

Override timeout with SimpleClientHttpRequestFactory

//Create resttemplate
RestTemplate restTemplate = new RestTemplate(getClientHttpRequestFactory());

//Override timeouts in request factory
private SimpleClientHttpRequestFactory getClientHttpRequestFactory() 
{
    SimpleClientHttpRequestFactory clientHttpRequestFactory
                      = new SimpleClientHttpRequestFactory();
    //Connect timeout
    clientHttpRequestFactory.setConnectTimeout(10_000);

    //Read timeout
    clientHttpRequestFactory.setReadTimeout(10_000);
    return clientHttpRequestFactory;
}

2. RestTemplate timeout with HttpComponentsClientHttpRequestFactory SimpleClientHttpRequestFactory helps in setting timeout but it is very limited in functionality and may not prove sufficient in realtime applications. In production code, we may want to use HttpComponentsClientHttpRequestFactory which support HTTP Client library along with resttemplate.

HTTPClient provides other useful features such as connection pool, idle connection management etc.

Override timeout with HttpComponentsClientHttpRequestFactory

//Create resttemplate
RestTemplate restTemplate = new RestTemplate(getClientHttpRequestFactory());

//Override timeouts in request factory
private SimpleClientHttpRequestFactory getClientHttpRequestFactory() 
{
    HttpComponentsClientHttpRequestFactory clientHttpRequestFactory
                      = new HttpComponentsClientHttpRequestFactory();
    //Connect timeout
    clientHttpRequestFactory.setConnectTimeout(10_000);

    //Read timeout
    clientHttpRequestFactory.setReadTimeout(10_000);
    return clientHttpRequestFactory;
}

Create a wrapper around properties and assume your A value has keys A.1, A.2, etc. Then when asked for A your wrapper will read all the A.* items and build the list. HTH

This is a pain in VS 2010, here's my workaround solution.

 public string DurationString
        {
            get 
            {
                if (this.Duration.TotalHours < 24)
                    return new DateTime(this.Duration.Ticks).ToString("HH:mm");
                else //If duration is more than 24 hours
                {
                    double totalminutes = this.Duration.TotalMinutes;
                    double hours = totalminutes / 60;
                    double minutes = this.Duration.TotalMinutes - (Math.Floor(hours) * 60);
                    string result = string.Format("{0}:{1}", Math.Floor(hours).ToString("00"), Math.Floor(minutes).ToString("00"));
                    return result;
                }
            } 
        }

No solution here worked for me. Instead I added a class to the label and was able to select it that way.

<asp:Label ID="Label1" CssClass="myLabel1Class" runat="server" Text="Label"></asp:Label>

$(".myLabel1Class").val()

And, as mentioned by others, make sure you have your jquery loaded.

You can define a DB class as below. Also, as andrewf suggested, use a context manager for cursor access.I'd define it as a member function. This way it keeps the connection open across multiple transactions from the app code and saves unnecessary reconnections to the server.

import pyodbc

class MS_DB():
    """ Collection of helper methods to query the MS SQL Server database.
    """

    def __init__(self, username, password, host, port=1433, initial_db='dev_db'):
        self.username = username
        self._password = password
        self.host = host
        self.port = str(port)
        self.db = initial_db
        conn_str = 'DRIVER=DRIVER=ODBC Driver 13 for SQL Server;SERVER='+ \
                    self.host + ';PORT='+ self.port +';DATABASE='+ \
                    self.db +';UID='+ self.username +';PWD='+ \ 
                    self._password +';'
        print('Connected to DB:', conn_str)
        self._connection = pyodbc.connect(conn_str)        
        pyodbc.pooling = False

    def __repr__(self):
        return f"MS-SQLServer('{self.username}', <password hidden>, '{self.host}', '{self.port}', '{self.db}')"

    def __str__(self):
        return f"MS-SQLServer Module for STP on {self.host}"

    def __del__(self):
        self._connection.close()
        print("Connection closed.")

    @contextmanager
    def cursor(self, commit: bool = False):
        """
        A context manager style of using a DB cursor for database operations. 
        This function should be used for any database queries or operations that

        :param commit:
        A boolean value that says whether to commit any database changes to the database. Defaults to False.
        :type commit: bool
        """
        cursor = self._connection.cursor()
        try:
            yield cursor
        except pyodbc.DatabaseError as err:
            print("DatabaseError {} ".format(err))
            cursor.rollback()
            raise err
        else:
            if commit:
                cursor.commit()
        finally:
            cursor.close()

ms_db = MS_DB(username='my_user', password='my_secret', host='hostname')
with ms_db.cursor() as cursor:
        cursor.execute("SELECT @@version;")
        print(cur.fetchall())

One method:

System.AppDomain.CurrentDomain.BaseDirectory

Another way to do it would be:

System.IO.Path.GetDirectoryName(System.Diagnostics.Process.GetCurrentProcess().MainModule.FileName)

$('#[element id]').val(null);

or

$('.[element class]').val(null);

With defining the file to import it's possible to use all folders common definitions.

So, @import "style/*" will compile all the files in the style folder.

More about import feature in Sass you can find here.

Here's how you can debug CORS requests using curl.

Sending a regular CORS request using cUrl:

curl -H "Origin: http://example.com" --verbose \
  https://www.googleapis.com/discovery/v1/apis?fields=

The -H "Origin: http://example.com" flag is the third party domain making the request. Substitute in whatever your domain is.

The --verbose flag prints out the entire response so you can see the request and response headers.

The url I'm using above is a sample request to a Google API that supports CORS, but you can substitute in whatever url you are testing.

The response should include the Access-Control-Allow-Origin header.

Sending a preflight request using cUrl:

curl -H "Origin: http://example.com" \
  -H "Access-Control-Request-Method: POST" \
  -H "Access-Control-Request-Headers: X-Requested-With" \
  -X OPTIONS --verbose \
  https://www.googleapis.com/discovery/v1/apis?fields=

This looks similar to the regular CORS request with a few additions:

The -H flags send additional preflight request headers to the server

The -X OPTIONS flag indicates that this is an HTTP OPTIONS request.

If the preflight request is successful, the response should include the Access-Control-Allow-Origin, Access-Control-Allow-Methods, and Access-Control-Allow-Headers response headers. If the preflight request was not successful, these headers shouldn't appear, or the HTTP response won't be 200.

You can also specify additional headers, such as User-Agent, by using the -H flag.

You need the Business Intelligence Studio ..I've checked and my version of VS2008 Pro doesn't have them installed.

Have a look at this link:

http://www.microsoft.com/downloads/details.aspx?familyid=3C856B93-369F-4C6F-9357-C35384179543&displaylang=en

A couple ways this can be done:

This will make it a square

ul
{
  list-style-type: square;
}

This will make it green

li
{
  color: #0F0;
}

This will prevent the text from being green

li p
{
  color: #000;
}

However that will require that all text within lists be in paragraphs so that the color is not overridden.

A better way is to make an image of a green square and use:

ul
{
  list-style: url(green-square.png);
}

An alternative method to using upgrade from the default CPAN shell is to use cpanminus and cpan-outdated.

These are so easy and nimble to use that I hardly ever go back to CPAN shell. To upgrade all of your modules in one go, the command is:

cpan-outdated -p | cpanm

I recommend you install cpanminus like the docs describe:

curl -L https://cpanmin.us | perl - App::cpanminus

And then install cpan-outdated along with all other CPAN modules using cpanm:

cpanm App::cpanoutdated

BTW: If you are using perlbrew then you will need to repeat this for every Perl you have installed under it.

You can find out more about cpanminus and cpan-outdated at the Github repos here:

• https://github.com/miyagawa/cpanminus
• https://github.com/tokuhirom/cpan-outdated

I solved it in a very simple way writing this in the "order" part

ORDER BY (
sr.codice +0
)
ASC

This seems to work very well, in fact I had the following sorting:

16079   Customer X 
016082  Customer Y
16413   Customer Z

So the 0 in front of 16082 is considered correctly.

You need to do something like this:

// instantiate XmlDocument and load XML from file
XmlDocument doc = new XmlDocument();
doc.Load(@"D:\test.xml");

// get a list of nodes - in this case, I'm selecting all <AID> nodes under
// the <GroupAIDs> node - change to suit your needs
XmlNodeList aNodes = doc.SelectNodes("/Equipment/DataCollections/GroupAIDs/AID");

// loop through all AID nodes
foreach (XmlNode aNode in aNodes)
{
   // grab the "id" attribute
   XmlAttribute idAttribute = aNode.Attributes["id"];

   // check if that attribute even exists...
   if (idAttribute != null)
   {
      // if yes - read its current value
      string currentValue = idAttribute.Value;

      // here, you can now decide what to do - for demo purposes,
      // I just set the ID value to a fixed value if it was empty before
      if (string.IsNullOrEmpty(currentValue))
      {
         idAttribute.Value = "515";
      }
   }
}

// save the XmlDocument back to disk
doc.Save(@"D:\test2.xml");

Maybe jcmd?

Jcmd utility is used to send diagnostic command requests to the JVM, where these requests are useful for controlling Java Flight Recordings, troubleshoot, and diagnose JVM and Java Applications.

The jcmd tool was introduced with Oracle's Java 7 and is particularly useful in troubleshooting issues with JVM applications by using it to identify Java processes' IDs (akin to jps), acquiring heap dumps (akin to jmap), acquiring thread dumps (akin to jstack), viewing virtual machine characteristics such as system properties and command-line flags (akin to jinfo), and acquiring garbage collection statistics (akin to jstat). The jcmd tool has been called "a swiss-army knife for investigating and resolving issues with your JVM application" and a "hidden gem."

Here’s the process you’ll need to use in invoking the jcmd:

1. Go to jcmd <pid> GC.heap_dump <file-path>
2. In which
3. pid: is a Java Process Id, for which the heap dump will be captured Also, the
4. file-path: is a file path in which the heap dump is be printed.

Check it out for more information about taking Java heap dump.

1. Select the top most line to the left (with you project name, number of targets, etc).
2. Select the target you wish to rename.
3. Click on the name of the target again.
4. Type the new name.
5. Press enter.

The error is coming because of the parser you are using. In general, if you have HTML file/code then you need to use html5lib(documentation can be found here) & in-case you have XML file/data then you need to use lxml(documentation can be found here). You can use lxml for HTML file/code also but sometimes it gives an error as above. So, better to choose the package wisely based on the type of data/file. You can also use html_parser which is built-in module. But, this also sometimes do not work.

For more details regarding when to use which package you can see the details here

Here is an example of decoding a generic map using both switch and reflection, so if you don't match the type, use reflection to figure it out and then add the type in next time.

var data map[string]interface {}

...

for k, v := range data {
    fmt.Printf("pair:%s\t%s\n", k, v)   

    switch t := v.(type) {
    case int:
        fmt.Printf("Integer: %v\n", t)
    case float64:
        fmt.Printf("Float64: %v\n", t)
    case string:
        fmt.Printf("String: %v\n", t)
    case bool:
        fmt.Printf("Bool: %v\n", t)
    case []interface {}:
        for i,n := range t {
            fmt.Printf("Item: %v= %v\n", i, n)
        }
    default:
        var r = reflect.TypeOf(t)
        fmt.Printf("Other:%v\n", r)             
    }
}

This is quite old question, but I have had the exact same annoying issue where everything worked fine for Chrome/Edge (with object-fit property) but same css property did not work in IE11 (since its unsupported in IE11), I ended up using HTML5 "figure" element which solved all my problems.

I personally did not use the outer DIV tag since that did not help at all in my case, so I avoided the outer DIV and simply replaced with 'figure' element.

The below code forces the image to reduce/scale down nicely (without changing the original aspect ratio).

<figure class="figure-class">
  <img class="image-class" src="{{photoURL}}" />
</figure>

and css classes:

.image-class {
    border: 6px solid #E8E8E8;
    max-width: 189px;
    max-height: 189px;
}

.figure-class {
    width: 189px;
    height: 189px;
}

 $.ajax({
            type: "POST",
            data: {data:the_id},
            url: "http://localhost/test/index.php/data/count_votes",
            success: function(data){
               //data will contain the vote count echoed by the controller i.e.  
                 "yourVoteCount"
              //then append the result where ever you want like
              $("span#votes_number").html(data); //data will be containing the vote count which you have echoed from the controller

                }
            });

in the controller

$data = $_POST['data'];  //$data will contain the_id
//do some processing
echo "yourVoteCount";

Clarification

i think you are confusing

{data:the_id}

with

success:function(data){

both the data are different for your own clarity sake you can modify it as

success:function(vote_count){
$(span#someId).html(vote_count);

I personally use a tooltip to display additional information, so when someone hovers over the event they can view a longer descriptions. This example uses qTip, but any tooltip implementation would work.

$(document).ready(function() {
    var date = new Date();
    var d = date.getDate();
    var m = date.getMonth();
    var y = date.getFullYear();
    $('#calendar').fullCalendar({
        header: {
            left: 'prev, next today',
            center: 'title',
            right: 'month, basicWeek, basicDay'
        },
        //events: "Calendar.asmx/EventList",
        //defaultView: 'dayView',
        events: [
        {
            title: 'All Day Event',
            start: new Date(y, m, 1),
            description: 'long description',
            id: 1
        },
        {
            title: 'Long Event',
            start: new Date(y, m, d - 5),
            end: new Date(y, m, 1),
            description: 'long description3',
            id: 2
        }],
        eventRender: function(event, element) {
            element.qtip({
                content: event.description + '<br />' + event.start,
                style: {
                    background: 'black',
                    color: '#FFFFFF'
                },
                position: {
                    corner: {
                        target: 'center',
                        tooltip: 'bottomMiddle'
                    }
                }
            });
        }
    });
});

Finally, I've a solution to my uploading problem.

In JavaScript:

var xhr = new XMLHttpRequest();
xhr.open("post", 'uploader.php', true);
xhr.setRequestHeader("pragma", "no-cache");

In PHP:

header('cache-control: no-cache');

This is one way to do it... there are likely 10 others that are better/more efficient, but it sounds like this is done very infrequently, so here goes...

get a list of the tables from sysobjects, then loop over those with a cursor, calling sp_execsql('truncate table ' + @table_name) for each iteration.

What exactly IS unit testing? Is it built into code or run as separate programs? Or something else?

From MSDN: The primary goal of unit testing is to take the smallest piece of testable software in the application, isolate it from the remainder of the code, and determine whether it behaves exactly as you expect.

Essentially, you are writing small bits of code to test the individual bits of your code. In the .net world, you would run these small bits of code using something like NUnit or MBunit or even the built in testing tools in visual studio. In Java you might use JUnit. Essentially the test runners will build your project, load and execute the unit tests and then let you know if they pass or fail.

How do you do it?

Well it's easier said than done to unit test. It takes quite a bit of practice to get good at it. You need to structure your code in a way that makes it easy to unit test to make your tests effective.

When should it be done? Are there times or projects not to do it? Is everything unit-testable?

You should do it where it makes sense. Not everything is suited to unit testing. For example UI code is very hard to unit test and you often get little benefit from doing so. Business Layer code however is often very suitable for tests and that is where most unit testing is focused.

Unit testing is a massive topic and to fully get an understanding of how it can best benefit you I'd recommend getting hold of a book on unit testing such as "Test Driven Development by Example" which will give you a good grasp on the concepts and how you can apply them to your code.

The existing explanations aren't really complete without the actual rule from the Standard, found in 6.7:

The zero-initialization of all block-scope variables with static storage duration or thread storage duration is performed before any other initialization takes place. Constant initialization of a block-scope entity with static storage duration, if applicable, is performed before its block is first entered. An implementation is permitted to perform early initialization of other block-scope variables with static or thread storage duration under the same conditions that an implementation is permitted to statically initialize a variable with static or thread storage duration in namespace scope. Otherwise such a variable is initialized the first time control passes through its declaration; such a variable is considered initialized upon the completion of its initialization. If the initialization exits by throwing an exception, the initialization is not complete, so it will be tried again the next time control enters the declaration. If control enters the declaration concurrently while the variable is being initialized, the concurrent execution shall wait for completion of the initialization. If control re-enters the declaration recursively while the variable is being initialized, the behavior is undefined.

On Lion the Users/[username]/Library is hidden.

To simply view in Finder, click the 'Go' menu at the top of the screen and hold down the 'alt' key to show 'Library'.

Click on 'Library' and you can see your previously hidden library folder.

Previously advised:

Use

chflags nohidden /users/[username]/library

in a terminal to display the folder.

That div.cell solution didn't actually work on my IPython, however luckily someone suggested a working solution for new IPythons:

Create a file ~/.ipython/profile_default/static/custom/custom.css (iPython) or ~/.jupyter/custom/custom.css (Jupyter) with content

.container { width:100% !important; }

Then restart iPython/Jupyter notebooks. Note that this will affect all notebooks.

If you give the enum a raw Int value it will make looping much easier.

For example, you can use anyGenerator to get a generator that can enumerate across your values:

enum Suit: Int, CustomStringConvertible {
    case Spades, Hearts, Diamonds, Clubs
    var description: String {
        switch self {
        case .Spades:   return "Spades"
        case .Hearts:   return "Hearts"
        case .Diamonds: return "Diamonds"
        case .Clubs:    return "Clubs"
        }
    }
    static func enumerate() -> AnyGenerator<Suit> {
        var nextIndex = Spades.rawValue
        return anyGenerator { Suit(rawValue: nextIndex++) }
    }
}
// You can now use it like this:
for suit in Suit.enumerate() {
    suit.description
}
// or like this:
let allSuits: [Suit] = Array(Suit.enumerate())

However, this looks like a fairly common pattern, wouldn't it be nice if we could make any enum type enumerable by simply conforming to a protocol? Well with Swift 2.0 and protocol extensions, now we can!

Simply add this to your project:

protocol EnumerableEnum {
    init?(rawValue: Int)
    static func firstValue() -> Int
}
extension EnumerableEnum {
    static func enumerate() -> AnyGenerator<Self> {
        var nextIndex = firstRawValue()
        return anyGenerator { Self(rawValue: nextIndex++) }
    }
    static func firstRawValue() -> Int { return 0 }
}

Now any time you create an enum (so long as it has an Int raw value), you can make it enumerable by conforming to the protocol:

enum Rank: Int, EnumerableEnum {
    case Ace, Two, Three, Four, Five, Six, Seven, Eight, Nine, Ten, Jack, Queen, King
}
// ...
for rank in Rank.enumerate() { ... }

If your enum values don't start with 0 (the default), override the firstRawValue method:

enum DeckColor: Int, EnumerableEnum {
    case Red = 10, Blue, Black
    static func firstRawValue() -> Int { return Red.rawValue }
}
// ...
let colors = Array(DeckColor.enumerate())

The final Suit class, including replacing simpleDescription with the more standard CustomStringConvertible protocol, will look like this:

enum Suit: Int, CustomStringConvertible, EnumerableEnum {
    case Spades, Hearts, Diamonds, Clubs
    var description: String {
        switch self {
        case .Spades:   return "Spades"
        case .Hearts:   return "Hearts"
        case .Diamonds: return "Diamonds"
        case .Clubs:    return "Clubs"
        }
    }
}
// ...
for suit in Suit.enumerate() {
    print(suit.description)
}

Swift 3 syntax:

protocol EnumerableEnum {
    init?(rawValue: Int)
    static func firstRawValue() -> Int
}

extension EnumerableEnum {
    static func enumerate() -> AnyIterator<Self> {
        var nextIndex = firstRawValue()

        let iterator: AnyIterator<Self> = AnyIterator {
            defer { nextIndex = nextIndex + 1 }
            return Self(rawValue: nextIndex)
        }

        return iterator
    }

    static func firstRawValue() -> Int {
        return 0
    }
}

One option:

run git gc manually to condense a number of pack files into one or a few pack files. This operation is persistent (i.e. the large pack file will retain its compression behavior) so it may be beneficial to compress a repository periodically with git gc --aggressive

Another option is to save the code and .git somewhere and then delete the .git and start again using this existing code, creating a new git repository (git init).

You could use pandas plot as @Bharath suggest:

import seaborn as sns
sns.set()
df.set_index('App').T.plot(kind='bar', stacked=True)

Output:

Updated:

from matplotlib.colors import ListedColormap df.set_index('App')\ .reindex_axis(df.set_index('App').sum().sort_values().index, axis=1)\ .T.plot(kind='bar', stacked=True, colormap=ListedColormap(sns.color_palette("GnBu", 10)), figsize=(12,6))

Updated Pandas 0.21.0+ reindex_axis is deprecated, use reindex

from matplotlib.colors import ListedColormap

df.set_index('App')\
  .reindex(df.set_index('App').sum().sort_values().index, axis=1)\
  .T.plot(kind='bar', stacked=True,
          colormap=ListedColormap(sns.color_palette("GnBu", 10)), 
          figsize=(12,6))

Output:

Just create a page-mytitle.php file to the folder of the current theme, and from the Dashboard a page "mytitle".

Then when you invoke the page by the URL you are going to see the page-mytitle.php. You must add HTML, CSS, JavaScript, wp-loop, etc. to this PHP file (page-mytitle.php).

The AppBar widget has a property called automaticallyImplyLeading. By default it's value is true. If you don't want flutter automatically build the back button for you then just make the property false.

appBar: AppBar(
  title: Text("YOUR_APPBAR_TITLE"), 
  automaticallyImplyLeading: false,
),

To add your custom back button

appBar: AppBar(
  title: Text("YOUR_APPBAR_TITLE"), 
  automaticallyImplyLeading: false,
  leading: YOUR_CUSTOM_WIDGET(),
),

Try this:

document.addEventListener("keydown", KeyCheck);  //or however you are calling your method
function KeyCheck(event)
{
   var KeyID = event.keyCode;
   switch(KeyID)
   {
      case 8:
      alert("backspace");
      break; 
      case 46:
      alert("delete");
      break;
      default:
      break;
   }
}

After reading John's answer, I discovered the following seemed to work for us (did not require specifying width):

<style>
.row {
    float:left;
    border: 1px solid yellow;
    overflow: visible;
    white-space: nowrap;
}

.cell {
    display: inline-block;
    border: 1px solid red;
    height: 100px;
}
</style>

<div class="row">
    <div class="cell">hello hello hello hello hello hello hello hello hello hello hello hello hello hello hello hello </div>
    <div class="cell">hello hello hello hello hello hello hello hello hello hello hello hello hello hello hello hello </div>
    <div class="cell">hello hello hello hello hello hello hello hello hello hello hello hello hello hello hello hello </div>
</div>

Bootstrap have a specific class for this: center-block

<button type="button" class="your_class center-block"> Book </button>

The state should be managed in the parent component. You can transfer the open value to the child component by adding a property.

class ParentComponent extends Component {
   constructor(props) {
      super(props);
      this.state = {
        open: false
      };

      this.toggleChildMenu = this.toggleChildMenu.bind(this);
   }

   toggleChildMenu() {
      this.setState(state => ({
        open: !state.open
      }));
   }

   render() {
      return (
         <div>
           <button onClick={this.toggleChildMenu}>
              Toggle Menu from Parent
           </button>
           <ChildComponent open={this.state.open} />
         </div>
       );
    }
}

class ChildComponent extends Component {
    render() {
      return (
         <Drawer open={this.props.open}/>
      );
    }
}

In case someone else ends up here struggling to customize admin form Many2Many saving behaviour, you can't call self.instance.my_m2m.add(obj) in your ModelForm.save override, as ModelForm.save later populates your m2m from self.cleaned_data['my_m2m'] which overwrites your changes. Instead call:

my_m2ms = list(self.cleaned_data['my_m2ms'])
my_m2ms.extend(my_custom_new_m2ms)
self.cleaned_data['my_m2ms'] = my_m2ms

(It is fine to convert the incoming QuerySet to a list - the ManyToManyField does that anyway.)

Perhaps you are looking for a context manager?

>>> class Foo(object):
...   def __init__(self):
...     self.bar = None
...   def __enter__(self):
...     if self.bar != 'open':
...       print 'opening the bar'
...       self.bar = 'open'
...   def __exit__(self, type_, value, traceback):
...     if self.bar != 'closed':
...       print 'closing the bar', type_, value, traceback
...       self.bar = 'close'
... 
>>> 
>>> with Foo() as f:
...     # oh no something crashes the program
...     sys.exit(0)
... 
opening the bar
closing the bar <type 'exceptions.SystemExit'> 0 <traceback object at 0xb7720cfc>

On CentOS 7, the following works:

yum install php-soap

This will automatically create a soap.ini under /etc/php.d.

The extension itself for me lives in /usr/lib64/php/modules. You can confirm your extension directory by doing:

php -i | grep extension_dir

Once this has been installed, you can simply restart Apache using the new service manager like so:

systemctl restart httpd

Thanks to Matt Browne for the info about /etc/php.d.

While I agree with CMS about doing this in an unobtrusive manner (via a lib like jquery or dojo), here's what also work:

<script type="text/javascript">
function parse(a, b, c) {
    alert(c);
  }

</script>

<a href="#x" onclick="parse('#', false, 'xyc&quot;foo');return false;">Test</a>

The reason it barfs is not because of JavaScript, it's because of the HTML parser. It has no concept of escaped quotes to it trundles along looking for the end quote and finds it and returns that as the onclick function. This is invalid javascript though so you don't find about the error until JavaScript tries to execute the function..

I found the answer in pure sed supplied by this question (admittedly, posted after this question was posted). This does exactly what you asked, solely in sed:

result=\`echo "$pid" | sed '/./ { s/pid:\ //g; }'\``

The dot in sed '/./) is whatever you want to match. Your question is exactly what I was attempting to, except in my case I wanted to match a specific line in a file and then uncomment it. In my case it was:

# Uncomment a line (edit the file in-place):
sed -i '/#\ COMMENTED_LINE_TO_MATCH/ { s/#\ //g; }' /path/to/target/file

The -i after sed is to edit the file in place (remove this switch if you want to test your matching expression prior to editing the file).

(I posted this because I wanted to do this entirely with sed as this question asked and none of the previous answered solved that problem.)

Probably there's something wrong with the input values for X and/or T. The function from the question works ok:

import numpy as np
from math import e

def sigmoid(X, T):
  return 1.0 / (1.0 + np.exp(-1.0 * np.dot(X, T)))

X = np.array([[1, 2, 3], [5, 0, 0]])
T = np.array([[1, 2], [1, 1], [4, 4]])

print(X.dot(T))
# Just to see if values are ok
print([1. / (1. + e ** el) for el in [-5, -10, -15, -16]])
print()
print(sigmoid(X, T))

Result:

[[15 16]
 [ 5 10]]

[0.9933071490757153, 0.9999546021312976, 0.999999694097773, 0.9999998874648379]

[[ 0.99999969  0.99999989]
 [ 0.99330715  0.9999546 ]]

Probably it's the dtype of your input arrays. Changing X to:

X = np.array([[1, 2, 3], [5, 0, 0]], dtype=object)

Gives:

Traceback (most recent call last):
  File "/[...]/stackoverflow_sigmoid.py", line 24, in <module>
    print sigmoid(X, T)
  File "/[...]/stackoverflow_sigmoid.py", line 14, in sigmoid
    return 1.0 / (1.0 + np.exp(-1.0 * np.dot(X, T)))

This should display the image inline:

.content-dir-item img.mail {
    display: inline-block;
    *display: inline; /* for older IE */
    *zoom: 1; /* for older IE */
}

This can be done without explicitly using hooks provided you add a prop to your component and a state to the stateless component's parent component:

const ParentComponent = props => {
  const [updateNow, setUpdateNow] = useState(true)

  const updateFunc = () => {
    setUpdateNow(!updateNow)
  }

  const MyComponent = props => {
    return (<div> .... </div>)
  }

  const MyButtonComponent = props => {
    return (<div> <input type="button" onClick={props.updateFunc} />.... </div>)
  }

  return (
    <div> 
      <MyComponent updateMe={updateNow} />
      <MyButtonComponent updateFunc={updateFunc}/>
    </div>
  )
}

Note: You can use memset with any character.

Example:

int arr[20];
memset(arr, 'A', sizeof(arr));

Also could be partially filled

int arr[20];
memset(&arr[5], 0, 10);

But be carefull. It is not limited for the array size, you could easily cause severe damage to your program doing something like this:

int arr[20];
memset(arr, 0, 200);

It is going to work (under windows) and zero memory after your array. It might cause damage to other variables values.

If you use action.BeginInvoke(), you have to call EndInvoke somewhere - else the framework has to hold the result of the async call on the heap, resulting in a memory leak.

If you don't want to jump to C# 5 with the async/await keywords, you can just use the Task Parallels library in .Net 4. It's much, much nicer than using BeginInvoke/EndInvoke, and gives a clean way to fire-and-forget for async jobs:

using System.Threading.Tasks;
...
void Foo(){}
...
new Task(Foo).Start();

If you have methods to call that take parameters, you can use a lambda to simplify the call without having to create delegates:

void Foo2(int x, string y)
{
    return;
}
...
new Task(() => { Foo2(42, "life, the universe, and everything");}).Start();

I'm pretty sure (but admittedly not positive) that the C# 5 async/await syntax is just syntactic sugar around the Task library.

1- Never use Response.Write.

2- I put the code below after create (not in Page_Load) a LinkButton (dynamically) and solved my problem:

ScriptManager scriptManager = ScriptManager.GetCurrent(this.Page);
scriptManager.RegisterPostBackControl(lblbtndoc1);

Under OSX, using reveal.js, I have got rendering issue if I just user tree and then copy/paste the output: strange symbols appear.

I have found 2 possible solutions.

1) Use charset ascii and simply copy/paste the output in the markdown file

tree -L 1 --charset=ascii

2) Use directly HTML and unicode in the markdown file

There are lots of ways. And this should work too in all browsers and you don't have to use document.getElementById anymore since you're passing the element itself to the function.

When I were trying install librosa package with pip (pip install librosa), this error were appeared:

ERROR: Cannot uninstall 'llvmlite'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.

I tried to remove llvmlite, but pip uninstall could not remove it. So, I used capability of ignore of pip by this code:

pip install librosa --ignore-installed llvmlite

Indeed, you can use this rule for ignoring a package you don't want to consider:

pip install {package you want to install} --ignore-installed {installed package you don't want to consider}

Here's a function I wrote which works similarly to the Unix time command:

function time {
    Param(
        [Parameter(Mandatory=$true)]
        [string]$command,
        [switch]$quiet = $false
    )
    $start = Get-Date
    try {
        if ( -not $quiet ) {
            iex $command | Write-Host
        } else {
            iex $command > $null
        }
    } finally {
        $(Get-Date) - $start
    }
}

The term "forward declaration" in C++ is mostly only used for class declarations. See (the end of) this answer for why a "forward declaration" of a class really is just a simple class declaration with a fancy name.

In other words, the "forward" just adds ballast to the term, as any declaration can be seen as being forward in so far as it declares some identifier before it is used.

(As to what is a declaration as opposed to a definition, again see What is the difference between a definition and a declaration?)

You have to close that application first. There is no way to delete it, if it's used by some application.

UnLock IT is a neat utility that helps you to take control of any file or folder when it is locked by some application or system. For every locked resource, you get a list of locking processes and can unlock it by terminating those processes. EMCO Unlock IT offers Windows Explorer integration that allows unlocking files and folders by one click in the context menu.

There's also Unlocker (not recommended, see Warning below), which is a free tool which helps locate any file locking handles running, and give you the option to turn it off. Then you can go ahead and do anything you want with those files.

Warning: The installer includes a lot of undesirable stuff. You're almost certainly better off with UnLock IT.

Maybe something like this...

try
{
    // ...
}
catch (WebException ex)
{
    if (ex.Status == WebExceptionStatus.ProtocolError)
    {
        var response = ex.Response as HttpWebResponse;
        if (response != null)
        {
            Console.WriteLine("HTTP Status Code: " + (int)response.StatusCode);
        }
        else
        {
            // no http status code available
        }
    }
    else
    {
        // no http status code available
    }
}

I had no luck getting tar to exclude a 5 Gigabyte subdirectory a few levels deep. In the end, I just used the unix Zip command. It worked a lot easier for me.

So for this particular example from the original post
(tar --exclude='./folder' --exclude='./upload/folder2' -zcvf /backup/filename.tgz . )

The equivalent would be:

zip -r /backup/filename.zip . -x upload/folder/**\* upload/folder2/**\*

(NOTE: Here is the post I originally used that helped me https://superuser.com/questions/312301/unix-zip-directory-but-excluded-specific-subdirectories-and-everything-within-t)

Short answer:

:%s/string-to-be-searched//gn

For learning:

There are 3 modes in VI editor as below

• : you are entering from Command to Command-line mode. Now, whatever you write after : is on CLI(Command Line Interface)
• %s specifies all lines. Specifying the range as % means do substitution in the entire file. Syntax for all occurrences substitution is :%s/old-text/new-text/g
• g specifies all occurrences in the line. With the g flag , you can make the whole line to be substituted. If this g flag is not used then only first occurrence in the line only will be substituted.
• n specifies to output number of occurrences
• //double slash represents omission of replacement text. Because we just want to find.

Once got the number of occurrences, you can Press N Key to see occurrences one-by-one.

For finding and counting in particular range of line number 1 to 10:

:1,10s/hello//gn

• Please note, % for whole file is repleaced by , separated line numbers.

For finding and replacing in particular range of line number 1 to 10:

:1,10s/helo/hello/gn

The easiest way is to just interrupt it with the usual Ctrl-C (SIGINT).

try:
    while True:
        do_something()
except KeyboardInterrupt:
    pass

Since Ctrl-C causes KeyboardInterrupt to be raised, just catch it outside the loop and ignore it.

Jokab's answer helped me a lot but in my case I could not push to github until I logged in my github account to my git bash so i ran the following commands

git config credential.helper store

then

git push http://github.com/[user name]/[repo name].git

After the second command a GUI window appeared, I provided my login credentials and it worked for me.

Remove VALUES from your SQL.

One alternate way if file contains strings without spaces with 1string each line:

fileItemString=$(cat  filename |tr "\n" " ")

fileItemArray=($fileItemString)

Check:

Print whole Array:

${fileItemArray[*]}

Length=${#fileItemArray[@]}

To add to those who have mentioned the implicit rules, it's best to see what make has defined implicitly and for your env using:

make -p

For instance:

%.o: %.c
    $(COMPILE.c) $(OUTPUT_OPTION) $<

which expands

COMPILE.c = $(CXX) $(CXXFLAGS) $(CPPFLAGS) $(TARGET_ARCH) -c

This will also print # environment data. Here, you will find GCC's include path among other useful info.

C_INCLUDE_PATH=/usr/include

In make, when it comes to search, the paths are many, the light is one... or something to that effect.

1. C_INCLUDE_PATH is system-wide, set it in your shell's *.rc.
2. $(CPPFLAGS) is for the preprocessor include path.
3. If you need to add a general search path for make, use:

VPATH = my_dir_to_search

... or even more specific

vpath %.c src
vpath %.h include

make uses VPATH as a general search path so use cautiously. If a file exists in more than one location listed in VPATH, make will take the first occurrence in the list.

Well actually github is much simpler than we think and absolutely it happens whenever we try to push even after we explicitly inserted some files in our git repository so, in order to fix the issue simply try..

: git pull

and then..

: git push

Note: if you accidently stuck in vim editor after pulling your repository than don't worry just close vim editor and try push :)

It will be fixed 64 chars, so use char(64)

On alternativ answer is this.

if you have and array like this: var contacts = [bob, mary];

and you want to put another array in this array, you can do that in this way:

Declare the function constructor

function add (firstName,lastName,email,phoneNumber) {
this.firstName = firstName;
this.lastName = lastName;
this.email = email;
this.phoneNumber = phoneNumber;
}

make the object from the function:

var add1 = new add("Alba","Fas","[email protected]","[098] 654365364");

and add the object in to the array:

contacts[contacts.length] = add1;

rm -rf .git should suffice. That will blow away all Git-related information.

Here's another way through the GUI that does exactly what your script does even though it goes through Indexes (not Constraints) in the object explorer.

1. Right click on "Indexes" and click "New Index..." (note: this is disabled if you have the table open in design view)

2. Give new index a name ("U_Name"), check "Unique", and click "Add..."

3. Select "Name" column in the next windown

4. Click OK in both windows

It is more Ruby-like to ask objects whether they respond to a method you need or not, using respond_to?. This allows both minimal interface and implementation unaware programming.

It is not always applicable of course, thus there is still a possibility to ask about more conservative understanding of "type", which is class or a base class, using the methods you're asking about.

static block is used for any technology to initialize static data member in dynamic way,or we can say for the dynamic initialization of static data member static block is being used..Because for non static data member initialization we have constructor but we do not have any place where we can dynamically initialize static data member

Eg:-class Solution{
         // static int x=10;
           static int x;
       static{
        try{
          x=System.out.println();
          }
         catch(Exception e){}
        }
       }

     class Solution1{
      public static void main(String a[]){
      System.out.println(Solution.x);
        }
        }

Now my static int x will initialize dynamically ..Bcoz when compiler will go to Solution.x it will load Solution Class and static block load at class loading time..So we can able to dynamically initialize that static data member..

}

There are two categories as follows

1. Core Java
2. Java EE

Core java is a language basics. For example (Data structures, Semantics..etc) https://malalanayake.wordpress.com/category/java/data-structures/

But if you see the Java EE you can see the Sevlet, JSP, JSF all the web technologies and the patterns. https://malalanayake.wordpress.com/2014/10/10/jsp-servlet-scope-variables-and-init-parameters/

Add a "User-Agent" header to your request.

Some servers attempt to block spidering programs and scrapers from accessing their server because, in earlier days, requests did not send a user agent header.

You can either try to set a custom user agent value or use some value that identifies a Browser like "Mozilla/5.0 Firefox/26.0"

RestTemplate restTemplate = new RestTemplate();
HttpHeaders headers = new HttpHeaders();

headers.setAccept(Arrays.asList(MediaType.APPLICATION_JSON));
headers.setContentType(MediaType.APPLICATION_JSON);
headers.add("user-agent", "Mozilla/5.0 Firefox/26.0");
headers.set("user-key", "your-password-123"); // optional - in case you auth in headers
HttpEntity<String> entity = new HttpEntity<String>("parameters", headers);
ResponseEntity<Game[]> respEntity = restTemplate.exchange(url, HttpMethod.GET, entity, Game[].class);

logger.info(respEntity.toString());

android.widget.Button.setOnClickListener(android.view.View$OnClickListener)' on a null object reference

Because Submit button is inside login_modal so you need to use loginDialog view to access button:

Submit = (Button)loginDialog.findViewById(R.id.Submit);

I hesitate to add yet another answer here as there are already quite a few, but a few points need to be made that have either not been made or not been made clearly.

First: Do not always use NVARCHAR. That is a very dangerous, and often costly, attitude / approach. And it is no better to say "Never use cursors" since they are sometimes the most efficient means of solving a particular problem, and the common work-around of doing a WHILE loop will almost always be slower than a properly done Cursor.

The only time you should use the term "always" is when advising to "always do what is best for the situation". Granted that is often difficult to determine, especially when trying to balance short-term gains in development time (manager: "we need this feature -- that you didn't know about until just now -- a week ago!") with long-term maintenance costs (manager who initially pressured team to complete a 3-month project in a 3-week sprint: "why are we having these performance problems? How could we have possibly done X which has no flexibility? We can't afford a sprint or two to fix this. What can we get done in a week so we can get back to our priority items? And we definitely need to spend more time in design so this doesn't keep happening!").

Second: @gbn's answer touches on some very important points to consider when making certain data modeling decisions when the path isn't 100% clear. But there is even more to consider:

• size of transaction log files
• time it takes to replicate (if using replication)
• time it takes to ETL (if ETLing)
• time it takes to ship logs to a remote system and restore (if using Log Shipping)
• size of backups
• length of time it takes to complete the backup
• length of time it takes to do a restore (this might be important some day ;-)
• size needed for tempdb
• performance of triggers (for inserted and deleted tables that are stored in tempdb)
• performance of row versioning (if using SNAPSHOT ISOLATION, since the version store is in tempdb)
• ability to get new disk space when the CFO says that they just spent $1 million on a SAN last year and so they will not authorize another $250k for additional storage
• length of time it takes to do INSERT and UPDATE operations
• length of time it takes to do index maintenance
• etc, etc, etc.

Wasting space has a huge cascade effect on the entire system. I wrote an article going into explicit detail on this topic: Disk Is Cheap! ORLY? (free registration required; sorry I don't control that policy).

Third: While some answers are incorrectly focusing on the "this is a small app" aspect, and some are correctly suggesting to "use what is appropriate", none of the answers have provided real guidance to the O.P. An important detail mentioned in the Question is that this is a web page for their school. Great! So we can suggest that:

• Fields for Student and/or Faculty names should probably be NVARCHAR since, over time, it is only getting more likely that names from other cultures will be showing up in those places.
• But for street address and city names? The purpose of the app was not stated (it would have been helpful) but assuming the address records, if any, pertain to just to a particular geographical region (i.e. a single language / culture), then use VARCHAR with the appropriate Code Page (which is determined from the Collation of the field).
• If storing State and/or Country ISO codes (no need to store INT / TINYINT since ISO codes are fixed length, human readable, and well, standard :) use CHAR(2) for two letter codes and CHAR(3) if using 3 letter codes. And consider using a binary Collation such as Latin1_General_100_BIN2.
• If storing postal codes (i.e. zip codes), use VARCHAR since it is an international standard to never use any letter outside of A-Z. And yes, still use VARCHAR even if only storing US zip codes and not INT since zip codes are not numbers, they are strings, and some of them have a leading "0". And consider using a binary Collation such as Latin1_General_100_BIN2.
• If storing email addresses and/or URLs, use NVARCHAR since both of those can now contain Unicode characters.
• and so on....

Fourth: Now that you have NVARCHAR data taking up twice as much space than it needs to for data that fits nicely into VARCHAR ("fits nicely" = doesn't turn into "?") and somehow, as if by magic, the application did grow and now there are millions of records in at least one of these fields where most rows are standard ASCII but some contain Unicode characters so you have to keep NVARCHAR, consider the following:

1. If you are using SQL Server 2008 - 2016 RTM and are on Enterprise Edition, OR if using SQL Server 2016 SP1 (which made Data Compression available in all editions) or newer, then you can enable Data Compression. Data Compression can (but won't "always") compress Unicode data in NCHAR and NVARCHAR fields. The determining factors are:

   1. NCHAR(1 - 4000) and NVARCHAR(1 - 4000) use the Standard Compression Scheme for Unicode, but only starting in SQL Server 2008 R2, AND only for IN ROW data, not OVERFLOW! This appears to be better than the regular ROW / PAGE compression algorithm.
   2. NVARCHAR(MAX) and XML (and I guess also VARBINARY(MAX), TEXT, and NTEXT) data that is IN ROW (not off row in LOB or OVERFLOW pages) can at least be PAGE compressed, but not ROW compressed. Of course, PAGE compression depends on size of the in-row value: I tested with VARCHAR(MAX) and saw that 6000 character/byte rows would not compress, but 4000 character/byte rows did.
   3. Any OFF ROW data, LOB or OVERLOW = No Compression For You!

2. If using SQL Server 2005, or 2008 - 2016 RTM and not on Enterprise Edition, you can have two fields: one VARCHAR and one NVARCHAR. For example, let's say you are storing URLs which are mostly all base ASCII characters (values 0 - 127) and hence fit into VARCHAR, but sometimes have Unicode characters. Your schema can include the following 3 fields:

     ...
     URLa VARCHAR(2048) NULL,
     URLu NVARCHAR(2048) NULL,
     URL AS (ISNULL(CONVERT(NVARCHAR([URLa])), [URLu])),
     CONSTRAINT [CK_TableName_OneUrlMax] CHECK (
                       ([URLa] IS NOT NULL OR [URLu] IS NOT NULL)
                   AND ([URLa] IS NULL OR [URLu] IS NULL))
   );
   

   In this model you only SELECT from the [URL] computed column. For inserting and updating, you determine which field to use by seeing if converting alters the incoming value, which has to be of NVARCHAR type:

   INSERT INTO TableName (..., URLa, URLu)
   VALUES (...,
           IIF (CONVERT(VARCHAR(2048), @URL) = @URL, @URL, NULL),
           IIF (CONVERT(VARCHAR(2048), @URL) <> @URL, NULL, @URL)
          );
   

3. You can GZIP incoming values into VARBINARY(MAX) and then unzip on the way out:

   • For SQL Server 2005 - 2014: you can use SQLCLR. SQL# (a SQLCLR library that I wrote) comes with Util_GZip and Util_GUnzip in the Free version
   • For SQL Server 2016 and newer: you can use the built-in COMPRESS and DECOMPRESS functions, which are also GZip.

4. If using SQL Server 2017 or newer, you can look into making the table a Clustered Columnstore Index.

5. While this is not a viable option yet, SQL Server 2019 introduces native support for UTF-8 in VARCHAR / CHAR datatypes. There are currently too many bugs with it for it to be used, but if they are fixed, then this is an option for some scenarios. Please see my post, "Native UTF-8 Support in SQL Server 2019: Savior or False Prophet?", for a detailed analysis of this new feature.

There are a few other choices in case the Adobe ActiveX isn't what you're looking for (since Acrobat must be present on the user machine and you can't ship it yourself).

For creating the PDF preview, first have a look at some other discussions on the subject on StackOverflow:

• How can I take preview of documents?
• Get a preview jpeg of a pdf on windows?
• .NET open PDF in winform without external dependencies
• PDF Previewing and viewing

In the last two I talk about a few things you can try:

• You can get a commercial renderer (PDFViewForNet, PDFRasterizer.NET, ABCPDF, ActivePDF, XpdfRasterizer and others in the other answers...).
  Most are fairly expensive though, especially if all you care about is making a simple preview/thumbnails.

• In addition to Omar Shahine's code snippet, there is a CodeProject article that shows how to use the Adobe ActiveX, but it may be out of date, easily broken by new releases and its legality is murky (basically it's ok for internal use but you can't ship it and you can't use it on a server to produce images of PDF).

• You could have a look at the source code for SumatraPDF, an OpenSource PDF viewer for windows.

• There is also Poppler, a rendering engine that uses Xpdf as a rendering engine. All of these are great but they will require a fair amount of commitment to make make them work and interface with .Net and they tend to be be distributed under the GPL.

• You may want to consider using GhostScript as an interpreter because rendering pages is a fairly simple process.
  The drawback is that you will need to either re-package it to install it with your app, or make it a pre-requisite (or at least a part of your install process).
  It's not a big challenge, and it's certainly easier than having to massage the other rendering engines into cooperating with .Net.
  I did a small project that you will find on the Developer Express forums as an attachment.
  Be careful of the license requirements for GhostScript through.
  If you can't leave with that then commercial software is probably your only choice.

yum -y remove php* to remove all php packages then you can install the 5.6 ones.

You can create a simple rule by doing something like this:

jQuery.validator.addMethod("greaterThanZero", function(value, element) {
    return this.optional(element) || (parseFloat(value) > 0);
}, "* Amount must be greater than zero");

And then applying this like so:

$('validatorElement').validate({
    rules : {
        amount : { greaterThanZero : true }
    }
});

Just change the contents of the 'addMethod' to validate your checkboxes.

I follow this way to append a new line in a .csv file:

pose_x = 1 
pose_y = 2

with open('path-to-your-csv-file.csv', mode='a') as file_:
    file_.write("{},{}".format(pose_x, pose_y))
    file_.write("\n")

A working example using the method mentioned above and using JSON to represent the data. This is used in my project of dealing with ajax calls fetching data from server.

http://jsfiddle.net/vinocui/22mX6/1/

In your html: < table id='here_table' >< /table >

JS code:

function feed_table(tableobj){
    // data is a JSON object with
    //{'id': 'table id',
    // 'header':[{'a': 'Asset Tpe', 'b' : 'Description', 'c' : 'Assets Value', 'd':'Action'}], 
    // 'data': [{'a': 'Non Real Estate',  'b' :'Credit card',  'c' :'$5000' , 'd': 'Edit/Delete' },...   ]}

    $('#' + tableobj.id).html( '' );

    $.each([tableobj.header, tableobj.data], function(_index, _obj){
    $.each(_obj, function(index, row){
        var line = "";
        $.each(row, function(key, value){
            if(0 === _index){
                line += '<th>' + value + '</th>';    
            }else{
                line += '<td>' + value + '</td>';
            }
        });
        line = '<tr>' + line + '</tr>';
        $('#' + tableobj.id).append(line);
    });


    });    
}

// testing
$(function(){
    var t = {
    'id': 'here_table',
    'header':[{'a': 'Asset Tpe', 'b' : 'Description', 'c' : 'Assets Value', 'd':'Action'}], 
    'data': [{'a': 'Non Real Estate',  'b' :'Credit card',  'c' :'$5000' , 'd': 'Edit/Delete' },
         {'a': 'Real Estate',  'b' :'Property',  'c' :'$500000' , 'd': 'Edit/Delete' }
        ]};

    feed_table(t);
});

I've learned that error messages like this are usually right. When it couldn't POSSIBLY (in your mind) be what the error being reported says, you go hunting for a problem in another area...only to find out hours later that the original error message was indeed right.

Since you're using Eclipse, I think Thilo has it right The most likely reason you are getting this message is because one of your projects is compiling 1.6 classes. It doesn't matter if you only have a 1.5 JRE on the system, because Eclipse has its own compiler (not javac), and only needs a 1.5 JRE to compile 1.6 classes. It may be weird, and a setting needs to be unchecked to allow this, but I just managed to do it.

For the project in question, check the Project Properties (usually Alt+Enter), Java Compiler section. Here's an image of a project configured to compile 1.6, but with only a 1.5 JRE.

You cannot concatenate a string with an int. You would need to convert your int to a string using the str function, or use formatting to format your output.

Change: -

print("Ok. Your balance is now at " + balanceAfterStrength + " skill points.")

to: -

print("Ok. Your balance is now at {} skill points.".format(balanceAfterStrength))

or: -

print("Ok. Your balance is now at " + str(balanceAfterStrength) + " skill points.")

or as per the comment, use , to pass different strings to your print function, rather than concatenating using +: -

print("Ok. Your balance is now at ", balanceAfterStrength, " skill points.")

For people just stumbling upon this now, I resolved an error of this type that was thrown with all the references and using statements placed properly. There's evidently some confusion with substituting in a function that returns DataTable instead of calling it on a declared DataTable. For example:

This worked for me:

DataTable dt = SomeObject.ReturnsDataTable();

List<string> ls = dt.AsEnumerable().Select(dr => dr["name"].ToString()).ToList<string>();

But this didn't:

List<string> ls = SomeObject.ReturnsDataTable().AsEnumerable().Select(dr => dr["name"].ToString()).ToList<string>();

I'm still not 100% sure why, but if anyone is frustrated by an error of this type, give this a try.

import re
re.sub('<.*?>', '', string)
"i think mabe 124 + but I don't have a big experience it just how I see it in my eyes fun stuff"

The re.sub function takes a regular expresion and replace all the matches in the string with the second parameter. In this case, we are searching for all tags ('<.*?>') and replacing them with nothing ('').

The ? is used in re for non-greedy searches.

More about the re module.

I'll post what worked for me, thanks to @xavi-montero.

Put your CSS in your bundle's Resource/public/css directory, and your images in say Resource/public/img.

Change assetic paths to the form 'bundles/mybundle/css/*.css', in your layout.

In config.yml, add rule css_rewrite to assetic:

assetic:
    filters:
        cssrewrite:
            apply_to: "\.css$"

Now install assets and compile with assetic:

$ rm -r app/cache/* # just in case
$ php app/console assets:install --symlink
$ php app/console assetic:dump --env=prod

This is good enough for the development box, and --symlink is useful, so you don't have to reinstall your assets (for example, you add a new image) when you enter through app_dev.php.

For the production server, I just removed the '--symlink' option (in my deployment script), and added this command at the end:

$ rm -r web/bundles/*/css web/bundles/*/js # all this is already compiled, we don't need the originals

All is done. With this, you can use paths like this in your .css files: ../img/picture.jpeg

You can do

int sum = lst.stream().filter(o -> o.getField() > 10).mapToInt(o -> o.getField()).sum();

or (using Method reference)

int sum = lst.stream().filter(o -> o.getField() > 10).mapToInt(Obj::getField).sum();

For people like me who get confused while using cmake, the FindCUDA.cmake script overrides some of the stuff from nvcc.profile. You can specify the nvcc host compiler by setting CUDA_HOST_COMPILER as per http://public.kitware.com/Bug/view.php?id=13674.

Reloading your whole activity may be a heavy task. Just put the part of code that has to be refreshed in (kotlin):

override fun onResume() {
    super.onResume()
    //here...
}

Java:

@Override
public void onResume(){
    super.onResume();
    //here...

}

And call "onResume()" whenever needed.

You should put the print function in your view-details.php file and call it once the file is loaded, by either using

<body onload="window.print()"> 

or

$(document).ready(function () { 
  window.print(); 
});

The query component is indicated by the first ? in a URI. "Query string" might be a synonym (this term is not used in the URI standard).

Some examples for HTTP URIs with query components:

http://example.com/foo?bar
http://example.com/foo/foo/foo?bar/bar/bar
http://example.com/?bar
http://example.com/?@bar._=???/1:
http://example.com/?bar1=a&bar2=b

(list of allowed characters in the query component)

The "format" of the query component is up to the URI authors. A common convention (but nothing more than a convention, as far as the URI standard is concerned¹) is to use the query component for key-value pairs, aka. parameters, like in the last example above: bar1=a&bar2=b.

Such parameters could also appear in the other URI components, i.e., the path² and the fragment. As far as the URI standard is concerned, it’s up to you which component and which format to use.

Example URI with parameters in the path, the query, and the fragment:

http://example.com/foo;key1=value1?key2=value2#key3=value3

¹ The URI standard says about the query component:

[…] query components are often used to carry identifying information in the form of "key=value" pairs […]

² The URI standard says about the path component:

[…] the semicolon (";") and equals ("=") reserved characters are often used to delimit parameters and parameter values applicable to that segment. The comma (",") reserved character is often used for similar purposes.

Since pandas 1.0.0 df.sort_values has a new parameter ignore_index which does exactly what you need:

In [1]: df2 = df.sort_values(by=['x','y'],ignore_index=True)

In [2]: df2
Out[2]:
   x  y
0  0  0
1  0  1
2  0  2
3  1  0
4  1  1
5  1  2
6  2  0
7  2  1
8  2  2

nobody seem to have offered the option to get the JSON directly from the Postgresql server, using the postgres JSON capability https://www.postgresql.org/docs/9.4/static/functions-json.html

No parsing, looping or any memory consumption on the python side, which you may really want to consider if you're dealing with 100,000's or millions of rows.

from django.db import connection

sql = 'SELECT to_json(result) FROM (SELECT * FROM TABLE table) result)'
with connection.cursor() as cursor:
  cursor.execute(sql)
  output = cursor.fetchall()

a table like:

id, value
----------
1     3
2     7

will return a Python JSON Object

[{"id": 1, "value": 3},{"id":2, "value": 7}]

Then use json.dumps to dump as a JSON string

Not exactly with HTML5 validation but a little JavaScript can resolve the issue, follow the example below:

<p>Password:</p>
<input name="password" required="required" type="password" id="password" />
<p>Confirm Password:</p>
<input name="password_confirm" required="required" type="password" id="password_confirm" oninput="check(this)" />
<script language='javascript' type='text/javascript'>
    function check(input) {
        if (input.value != document.getElementById('password').value) {
            input.setCustomValidity('Password Must be Matching.');
        } else {
            // input is valid -- reset the error message
            input.setCustomValidity('');
        }
    }
</script>
<br /><br />
<input type="submit" />

There will definitely be a bean also containing fields related to Birthday So use this and your issue will be resolved

@SpringBootApplication
@EntityScan("com.java.model*")  // base package where bean is present
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

I recently had the requirement to use JNDI with an embedded Tomcat in Spring Boot.
Actual answers give some interesting hints to solve my task but it was not enough as probably not updated for Spring Boot 2.

Here is my contribution tested with Spring Boot 2.0.3.RELEASE.

Specifying a datasource available in the classpath at runtime

You have multiple choices :

• using the DBCP 2 datasource (you don't want to use DBCP 1 that is outdated and less efficient).
• using the Tomcat JDBC datasource.
• using any other datasource : for example HikariCP.

If you don't specify anyone of them, with the default configuration the instantiation of the datasource will throw an exception :

• To use Apache JDBC datasource, you don't need to add any dependency but you have to change the default factory class to org.apache.tomcat.jdbc.pool.DataSourceFactory.
  You can do it in the resource declaration : resource.setProperty("factory", "org.apache.tomcat.jdbc.pool.DataSourceFactory"); I will explain below where add this line.

• To use DBCP 2 datasource a dependency is required:

  <dependency> <groupId>org.apache.tomcat</groupId> <artifactId>tomcat-dbcp</artifactId> <version>8.5.4</version> </dependency>

Of course, adapt the artifact version according to your Spring Boot Tomcat embedded version.

• To use HikariCP, add the required dependency if not already present in your configuration (it may be if you rely on persistence starters of Spring Boot) such as :

  <dependency> <groupId>com.zaxxer</groupId> <artifactId>HikariCP</artifactId> <version>3.1.0</version> </dependency>

and specify the factory that goes with in the resource declaration:

resource.setProperty("factory", "com.zaxxer.hikari.HikariJNDIFactory");

Datasource configuration/declaration

You have to customize the bean that creates the TomcatServletWebServerFactory instance.
Two things to do :

• enabling the JNDI naming which is disabled by default

• creating and add the JNDI resource(s) in the server context

For example with PostgreSQL and a DBCP 2 datasource, do that :

@Bean
public TomcatServletWebServerFactory tomcatFactory() {
    return new TomcatServletWebServerFactory() {
        @Override
        protected TomcatWebServer getTomcatWebServer(org.apache.catalina.startup.Tomcat tomcat) {
            tomcat.enableNaming(); 
            return super.getTomcatWebServer(tomcat);
        }

        @Override 
        protected void postProcessContext(Context context) {

            // context
            ContextResource resource = new ContextResource();
            resource.setName("jdbc/myJndiResource");
            resource.setType(DataSource.class.getName());
            resource.setProperty("driverClassName", "org.postgresql.Driver");

            resource.setProperty("url", "jdbc:postgresql://hostname:port/dbname");
            resource.setProperty("username", "username");
            resource.setProperty("password", "password");
            context.getNamingResources()
                   .addResource(resource);          
        }
    };
}

Here the variants for Tomcat JDBC and HikariCP datasource.

In postProcessContext() set the factory property as explained early for Tomcat JDBC ds :

    @Override 
    protected void postProcessContext(Context context) {
        ContextResource resource = new ContextResource();       
        //...
        resource.setProperty("factory", "org.apache.tomcat.jdbc.pool.DataSourceFactory");
        //...
        context.getNamingResources()
               .addResource(resource);          
    }
};

and for HikariCP :

    @Override 
    protected void postProcessContext(Context context) {
        ContextResource resource = new ContextResource();       
        //...
        resource.setProperty("factory", "com.zaxxer.hikari.HikariDataSource");
        //...
        context.getNamingResources()
               .addResource(resource);          
    }
};

Using/Injecting the datasource

You should now be able to lookup the JNDI ressource anywhere by using a standard InitialContext instance :

InitialContext initialContext = new InitialContext();
DataSource datasource = (DataSource) initialContext.lookup("java:comp/env/jdbc/myJndiResource");

You can also use JndiObjectFactoryBean of Spring to lookup up the resource :

JndiObjectFactoryBean bean = new JndiObjectFactoryBean();
bean.setJndiName("java:comp/env/jdbc/myJndiResource");
bean.afterPropertiesSet();
DataSource object = (DataSource) bean.getObject();

To take advantage of the DI container you can also make the DataSource a Spring bean :

@Bean(destroyMethod = "")
public DataSource jndiDataSource() throws IllegalArgumentException, NamingException {
    JndiObjectFactoryBean bean = new JndiObjectFactoryBean();
    bean.setJndiName("java:comp/env/jdbc/myJndiResource");
    bean.afterPropertiesSet();
    return (DataSource) bean.getObject();
}

And so you can now inject the DataSource in any Spring beans such as :

@Autowired
private DataSource jndiDataSource;

Note that many examples on the internet seem to disable the lookup of the JNDI resource on startup :

bean.setJndiName("java:comp/env/jdbc/myJndiResource");
bean.setProxyInterface(DataSource.class);
bean.setLookupOnStartup(false);
bean.afterPropertiesSet(); 

But I think that it is helpless as it invokes just after afterPropertiesSet() that does the lookup !

If you want to check the display value, https://stackoverflow.com/a/1189281/5622596 already posted the answer.

However if instead of checking whether an element has a style of style="display:none" you want to know if that element is visible. Then use .is(":visible")

For example: $('#idDetails').is(":visible");

This will be true if it is visible & false if it is not.

For eg.,. 2 fields are added in a model like below..

description = models.TextField(blank=True, null=True)
title = models.CharField(max_length=64, blank=True, null=True)

Below are the mysql queries executed when migrations are applied.

for TextField(description) the field is defined as a longtext

ALTER TABLE `sometable_sometable` ADD COLUMN `description` longtext NULL;

The maximum length of TextField of MySQL is 4GB according to string-type-overview.

for CharField(title) the max_length(required) is defined as varchar(64)

ALTER TABLE `sometable_sometable` ADD COLUMN `title` varchar(64) NULL;
ALTER TABLE `sometable_sometable` ALTER COLUMN `title` DROP DEFAULT;

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

SELECT * FROM  mysql.general_log  WHERE command_type ='Query' LIMIT total;

For Android 6.0+ the game has changed so i suggest you use this;

The best way to go is during runtime else you get permission errors.

Hope this helps you or someone.

You can simplify this code to:

        DirectorySearcher searcher = new DirectorySearcher();
        searcher.Filter = "(&(objectCategory=user)(cn=steve.evans))";

        SearchResultCollection results = searcher.FindAll();

        if (results.Count == 1)
        {
            //do what you want to do
        }
        else if (results.Count == 0)
        {
            //user does not exist
        }
        else
        {
            //found more than one user
            //something is wrong
        }

If you can narrow down where the user is you can set searcher.SearchRoot to a specific OU that you know the user is under.

You should also use objectCategory instead of objectClass since objectCategory is indexed by default.

You should also consider searching on an attribute other than CN. For example it might make more sense to search on the username (sAMAccountName) since it's guaranteed to be unique.

We can convert Today's date in the format of 'JUN 12, 2020'.

String.valueOf(DateFormat.getDateInstance().format(new Date())));

We have a large .SLN files with many project files. I started the policy of having a "ViewLocal" directory where all non-sourcecontrolled files are located. Inside that directory is an 'Inter' and an 'Out' directory. For the intermediate files, and the output files, respectively.

This obviously makes it easy to just go to your 'viewlocal' directory and do a simple delete, to get rid of everything.

Before you spent time figuring out a way to work around this with scripts, you might think about setting up something similar.

I won't lie though, maintaining such a setup in a large organization has proved....interesting. Especially when you use technologies such as QT that like to process files and create non-sourcecontrolled source files. But that is a whole OTHER story!

Use setLocationRelativeTo(null)

This method has a special effect when you pass it a null. According to the Javadoc:

If the component is null, or the GraphicsConfiguration associated with this component is null, the window is placed in the center of the screen.

This should be done after setting the size or calling pack(), but before setting it visible, like this:

frame.pack();
frame.setLocationRelativeTo(null);
frame.setVisible(true);

random_state number splits the test and training datasets with a random manner. In addition to what is explained here, it is important to remember that random_state value can have significant effect on the quality of your model (by quality I essentially mean accuracy to predict). For instance, If you take a certain dataset and train a regression model with it, without specifying the random_state value, there is the potential that everytime, you will get a different accuracy result for your trained model on the test data. So it is important to find the best random_state value to provide you with the most accurate model. And then, that number will be used to reproduce your model in another occasion such as another research experiment. To do so, it is possible to split and train the model in a for-loop by assigning random numbers to random_state parameter:

for j in range(1000):

            X_train, X_test, y_train, y_test = train_test_split(X, y , random_state =j,     test_size=0.35)
            lr = LarsCV().fit(X_train, y_train)

            tr_score.append(lr.score(X_train, y_train))
            ts_score.append(lr.score(X_test, y_test))

        J = ts_score.index(np.max(ts_score))

        X_train, X_test, y_train, y_test = train_test_split(X, y , random_state =J, test_size=0.35)
        M = LarsCV().fit(X_train, y_train)
        y_pred = M.predict(X_test)`

As others said, Stopwatch should be the right tool for this. There can be few improvements made to it though, see this thread specifically: Benchmarking small code samples in C#, can this implementation be improved?.

I have seen some useful tips by Thomas Maierhofer here

Basically his code looks like:

//prevent the JIT Compiler from optimizing Fkt calls away
long seed = Environment.TickCount;

//use the second Core/Processor for the test
Process.GetCurrentProcess().ProcessorAffinity = new IntPtr(2);

//prevent "Normal" Processes from interrupting Threads
Process.GetCurrentProcess().PriorityClass = ProcessPriorityClass.High;

//prevent "Normal" Threads from interrupting this thread
Thread.CurrentThread.Priority = ThreadPriority.Highest;

//warm up
method();

var stopwatch = new Stopwatch()
for (int i = 0; i < repetitions; i++)
{
    stopwatch.Reset();
    stopwatch.Start();
    for (int j = 0; j < iterations; j++)
        method();
    stopwatch.Stop();
    print stopwatch.Elapsed.TotalMilliseconds;
}

Another approach is to rely on Process.TotalProcessTime to measure how long the CPU has been kept busy running the very code/process, as shown here This can reflect more real scenario since no other process affects the measurement. It does something like:

 var start = Process.GetCurrentProcess().TotalProcessorTime;
 method();
 var stop = Process.GetCurrentProcess().TotalProcessorTime;
 print (end - begin).TotalMilliseconds;

A naked, detailed implementation of the samething can be found here.

I wrote a helper class to perform both in an easy to use manner:

public class Clock
{
    interface IStopwatch
    {
        bool IsRunning { get; }
        TimeSpan Elapsed { get; }

        void Start();
        void Stop();
        void Reset();
    }



    class TimeWatch : IStopwatch
    {
        Stopwatch stopwatch = new Stopwatch();

        public TimeSpan Elapsed
        {
            get { return stopwatch.Elapsed; }
        }

        public bool IsRunning
        {
            get { return stopwatch.IsRunning; }
        }



        public TimeWatch()
        {
            if (!Stopwatch.IsHighResolution)
                throw new NotSupportedException("Your hardware doesn't support high resolution counter");

            //prevent the JIT Compiler from optimizing Fkt calls away
            long seed = Environment.TickCount;

            //use the second Core/Processor for the test
            Process.GetCurrentProcess().ProcessorAffinity = new IntPtr(2);

            //prevent "Normal" Processes from interrupting Threads
            Process.GetCurrentProcess().PriorityClass = ProcessPriorityClass.High;

            //prevent "Normal" Threads from interrupting this thread
            Thread.CurrentThread.Priority = ThreadPriority.Highest;
        }



        public void Start()
        {
            stopwatch.Start();
        }

        public void Stop()
        {
            stopwatch.Stop();
        }

        public void Reset()
        {
            stopwatch.Reset();
        }
    }



    class CpuWatch : IStopwatch
    {
        TimeSpan startTime;
        TimeSpan endTime;
        bool isRunning;



        public TimeSpan Elapsed
        {
            get
            {
                if (IsRunning)
                    throw new NotImplementedException("Getting elapsed span while watch is running is not implemented");

                return endTime - startTime;
            }
        }

        public bool IsRunning
        {
            get { return isRunning; }
        }



        public void Start()
        {
            startTime = Process.GetCurrentProcess().TotalProcessorTime;
            isRunning = true;
        }

        public void Stop()
        {
            endTime = Process.GetCurrentProcess().TotalProcessorTime;
            isRunning = false;
        }

        public void Reset()
        {
            startTime = TimeSpan.Zero;
            endTime = TimeSpan.Zero;
        }
    }



    public static void BenchmarkTime(Action action, int iterations = 10000)
    {
        Benchmark<TimeWatch>(action, iterations);
    }

    static void Benchmark<T>(Action action, int iterations) where T : IStopwatch, new()
    {
        //clean Garbage
        GC.Collect();

        //wait for the finalizer queue to empty
        GC.WaitForPendingFinalizers();

        //clean Garbage
        GC.Collect();

        //warm up
        action();

        var stopwatch = new T();
        var timings = new double[5];
        for (int i = 0; i < timings.Length; i++)
        {
            stopwatch.Reset();
            stopwatch.Start();
            for (int j = 0; j < iterations; j++)
                action();
            stopwatch.Stop();
            timings[i] = stopwatch.Elapsed.TotalMilliseconds;
            print timings[i];
        }
        print "normalized mean: " + timings.NormalizedMean().ToString();
    }

    public static void BenchmarkCpu(Action action, int iterations = 10000)
    {
        Benchmark<CpuWatch>(action, iterations);
    }
}

Just call

Clock.BenchmarkTime(() =>
{
    //code

}, 10000000);

or

Clock.BenchmarkCpu(() =>
{
    //code

}, 10000000);

The last part of the Clock is the tricky part. If you want to display the final timing, its up to you to choose what sort of timing you want. I wrote an extension method NormalizedMean which gives you the mean of the read timings discarding the noise. I mean I calculate the the deviation of each timing from the actual mean, and then I discard the values which was farer (only the slower ones) from the mean of deviation (called absolute deviation; note that its not the often heard standard deviation), and finally return the mean of remaining values. This means, for instance, if timed values are { 1, 2, 3, 2, 100 } (in ms or whatever), it discards 100, and returns the mean of { 1, 2, 3, 2 } which is 2. Or if timings are { 240, 220, 200, 220, 220, 270 }, it discards 270, and returns the mean of { 240, 220, 200, 220, 220 } which is 220.

public static double NormalizedMean(this ICollection<double> values)
{
    if (values.Count == 0)
        return double.NaN;

    var deviations = values.Deviations().ToArray();
    var meanDeviation = deviations.Sum(t => Math.Abs(t.Item2)) / values.Count;
    return deviations.Where(t => t.Item2 > 0 || Math.Abs(t.Item2) <= meanDeviation).Average(t => t.Item1);
}

public static IEnumerable<Tuple<double, double>> Deviations(this ICollection<double> values)
{
    if (values.Count == 0)
        yield break;

    var avg = values.Average();
    foreach (var d in values)
        yield return Tuple.Create(d, avg - d);
}

I had the same issue - js error box in IE - this works fine in all browsers as far as I can see (event.cancelBubble=true does the job in IE)

onClick="if(event.stopPropagation){event.stopPropagation();}event.cancelBubble=true;"

EDIT: I hadn't noticed you needed the position as well. You can't use IndexOf directly on a value of an array type, because it's implemented explicitly. However, you can use:

IList<string> arrayAsList = (IList<string>) stringArray;
int index = arrayAsList.IndexOf(value);
if (index != -1)
{
    ...
}

(This is similar to calling Array.IndexOf as per Darin's answer - just an alternative approach. It's not clear to me why IList<T>.IndexOf is implemented explicitly in arrays, but never mind...)

I had

numpy.array(n * [value])

in mind, but apparently that is slower than all other suggestions for large enough n.

Here is full comparison with perfplot (a pet project of mine).

The two empty alternatives are still the fastest (with NumPy 1.12.1). full catches up for large arrays.

Code to generate the plot:

import numpy as np
import perfplot


def empty_fill(n):
    a = np.empty(n)
    a.fill(3.14)
    return a


def empty_colon(n):
    a = np.empty(n)
    a[:] = 3.14
    return a


def ones_times(n):
    return 3.14 * np.ones(n)


def repeat(n):
    return np.repeat(3.14, (n))


def tile(n):
    return np.repeat(3.14, [n])


def full(n):
    return np.full((n), 3.14)


def list_to_array(n):
    return np.array(n * [3.14])


perfplot.show(
    setup=lambda n: n,
    kernels=[empty_fill, empty_colon, ones_times, repeat, tile, full, list_to_array],
    n_range=[2 ** k for k in range(27)],
    xlabel="len(a)",
    logx=True,
    logy=True,
)

Summary

Simply prevent the default browser action:

window.addEventListener("keydown", function(e) {
    // space and arrow keys
    if([32, 37, 38, 39, 40].indexOf(e.code) > -1) {
        e.preventDefault();
    }
}, false);

If you need to support Internet Explorer or other older browsers, use e.keyCode instead of e.code, but keep in mind that keyCode is deprecated.

Original answer

I used the following function in my own game:

var keys = {};
window.addEventListener("keydown",
    function(e){
        keys[e.code] = true;
        switch(e.code){
            case 37: case 39: case 38:  case 40: // Arrow keys
            case 32: e.preventDefault(); break; // Space
            default: break; // do not block other keys
        }
    },
false);
window.addEventListener('keyup',
    function(e){
        keys[e.code] = false;
    },
false);

The magic happens in e.preventDefault();. This will block the default action of the event, in this case moving the viewpoint of the browser.

If you don't need the current button states you can simply drop keys and just discard the default action on the arrow keys:

var arrow_keys_handler = function(e) {
    switch(e.code){
        case 37: case 39: case 38:  case 40: // Arrow keys
        case 32: e.preventDefault(); break; // Space
        default: break; // do not block other keys
    }
};
window.addEventListener("keydown", arrow_keys_handler, false);

Note that this approach also enables you to remove the event handler later if you need to re-enable arrow key scrolling:

window.removeEventListener("keydown", arrow_keys_handler, false);

You can use -k option to run test cases with different patterns:

py.test tests_directory/foo.py tests_directory/bar.py -k 'test_001 or test_some_other_test'

This will run test cases with name test_001 and test_some_other_test deselecting the rest of the test cases.

Note: This will select any test case starting with test_001 or test_some_other_test. For example, if you have test case test_0012 it will also be selected.

Here is also the code to handle the result:

def foo (a):
    x=a
    y=a*2
    return (x,y)

(x,y) = foo(50)

Curl gives this error when there is no reply from a server, since it is an error for HTTP not to respond anything to a request.

I suspect the problem you have is that there is some piece of network infrastructure, like a firewall or a proxy, between you and the host in question. Getting this to work, therefore, will require you to discuss the issue with the people responsible for that hardware.

<div class="crop">longlong longlong longlong longlong longlong longlong </div>?

This is one possible approach i can think of

.crop {width:100px;overflow:hidden;height:50px;line-height:50px;}?

This way the long text will still wrap but will not be visible due to overflow set, and by setting line-height same as height we are making sure only one line will ever be displayed.

See demo here and nice overflow property description with interactive examples.

google.maps.event.addListener(marker, 'click', (function(marker, i) {
  return function() {
    window.location.href = marker.url;
  }
})(marker, i));

Is sku just a property of the Product model? If so:

$products = Product::whereOwnerAndStatus($owner, 0)->take($count)->get();

foreach ($products as $product ) {
  // Access $product->sku here...
}

Or is sku a relationship to another model? If that is the case, then, as long as your relationship is setup properly, you code should work.

You could try my (*heavily borrowed from various sites) recursive method to go through all JSON objects and JSON arrays until you find JSON elements. This example actually searches for a particular key and returns all values for all instances of that key. 'searchKey' is the key you are looking for.

ArrayList<String> myList = new ArrayList<String>();
myList = findMyKeyValue(yourJsonPayload,null,"A"); //if you only wanted to search for A's values

    private ArrayList<String> findMyKeyValue(JsonElement element, String key, String searchKey) {

    //OBJECT
    if(element.isJsonObject()) {
        JsonObject jsonObject = element.getAsJsonObject();

        //loop through all elements in object

        for (Map.Entry<String,JsonElement> entry : jsonObject.entrySet()) {
            JsonElement array = entry.getValue();
            findMyKeyValue(array, entry.getKey(), searchKey);

        }

    //ARRAY
    } else if(element.isJsonArray()) {
        //when an array is found keep 'key' as that is the array's name i.e. pass it down

        JsonArray jsonArray = element.getAsJsonArray();

        //loop through all elements in array
        for (JsonElement childElement : jsonArray) {
            findMyKeyValue(childElement, key, searchKey);
        }

    //NEITHER
    } else {

        //System.out.println("SKey: " + searchKey + " Key: " + key );

            if (key.equals(searchKey)){
                listOfValues.add(element.getAsString());
            }
    }
    return listOfValues;
}

1. Right-click on the toolbar and select Customize...
2. Select the Commands tab.
3. Under Categories click on Edit, then select Comment Block in the Commands listbox.
4. Drag the Comment Block entry onto the Menu Bar (yep! the menu bar)
   Note: You should now see a new icon on the menu bar.
5. Make sure that the new icon is highlighted (it will have a black square around it) then
   click Modify Selection button on the Customize dialog box.
6. An interesting menu will popup.
   Under name, add an ampersand (&) to the beginning of the entry.
   So now instead of "Comment Block" it should read &Comment Block.
   Press Enter to save the change.
7. Click on Modify Selection again and select Image and Text.
8. Dismiss the Customize dialog box.
9. Highlight any block of code and press Alt-C. Voila.
10. Do the same thing for the Uncomment Block or
    any other commands that you find yourself using often.

If you have a Mac you can get jsc a javascript console in OS X (Terminal) by typing

/System/Library/Frameworks/JavaScriptCore.framework/Versions/Current/Resources/jsc

in Terminal.app.

You could also run one of your .js script by adding its name as an argument for jsc, like this:

jsc your_awesome_script_name.js

Notice: I use console.log() during development but jsc needs the debug() function instead.

On Ubuntu you have some nice ECMAScript shells at your disposal. Between them it's worth to mention SpiderMonkey. You can add It by sudo apt-get install spidermonkey

On Windows as other people said you can rely on cscript and wscript directly built on the OS.

I would add also another :) way of thinking to the problem, if you have time and like to learn new things i'd like to mention coffee-script that has its own compiler/console and gives you super-correct Javascript out. You can try it also on your browser (link "try coffeescript").

If last versions means last tag, and current versions means HEAD (current state), it's just a diff with the last tag:

Looking for tags:

$ git tag --list
...
v20.11.23.4
v20.11.25.1
v20.11.25.2
v20.11.25.351

The last tag would be:

$ git tag --list | tail -n 1
v20.11.25.351

Putting it together:

tag=$(git tag --list | tail -n 1)
git diff $tag

In my case, I want to clear out old files at the beginning of the build, but this is problematic since the source code has been checked out.

My solution is to ask git to clean out any files (from the last build) that it doesn't know about:

    sh "git clean -x -f"

That way I can start the build out clean, and if it fails, the workspace isn't cleaned out and therefore easily debuggable.

try this (ExtensionMethods):

public static string ToJson(this DataTable dt)
{
    List<Dictionary<string, object>> lst = new List<Dictionary<string, object>>();
    Dictionary<string, object> item;
    foreach (DataRow row in dt.Rows)
    {
            item = new Dictionary<string, object>();
                foreach (DataColumn col in dt.Columns)
                {
                    item.Add(col.ColumnName, (Convert.IsDBNull(row[col]) ? null : row[col]));       
        }
        lst.Add(item);
    }
        return Newtonsoft.Json.JsonConvert.SerializeObject(lst);
}

and use:

DataTable dt = new DataTable();
.
.
.
var json = dt.ToJson();

There are multiple ways to achieve this:

1. By using --simulator flag
2. By using --udid flag

Firstly you need to list all the available devices. To list all the devices run

xcrun simctl list device

This will give output as follows:

These are the available devices for iOS 13.0 onwards:

I hope this answer helped you.

There is nothing to do with jQuery and if you want to use it I advice you to do

if (window.console) {
    console.log("your message")
}

So you don't break your code when it is not available.

As suggested in the comment, you can also execute that in one place and then use console.log as normal

if (!window.console) { window.console = { log: function(){} }; }

SQLFiddle will let you test out your queries, while it doesn't explicitly correct syntax etc. per se it does let you play around with the script and will definitely let you know if things are working or not.

If you scale 1600x900 to 1280x720 you have

scale_x = 1280.0/1600
scale_y = 720.0/900

Then you can use it to find button size, and button position

button_width  = 300 * scale_x
button_height = 300 * scale_y

button_x = 1440 * scale_x
button_y = 860  * scale_y

If you scale 1280x720 to 1600x900 you have

scale_x = 1600.0/1280
scale_y = 900.0/720

and rest is the same.

I add .0 to value to make float - otherwise scale_x, scale_y will be rounded to integer - in this example to 0 (zero) (Python 2.x)

In Java, a String is a reference to heap-allocated storage. Returning "ans" only returns the reference so there is no need for stack-allocated storage. In fact, there is no way in Java to allocate objects in stack storage.

I would change to this, though. You don't need "ans" at all.

return String.format("%d:%d", mins, secs);

The strict equality operator (===) behaves identically to the abstract equality operator (==) except no type conversion is done, and the types must be the same to be considered equal.

Reference: Javascript Tutorial: Comparison Operators

The == operator will compare for equality after doing any necessary type conversions. The === operator will not do the conversion, so if two values are not the same type === will simply return false. Both are equally quick.

To quote Douglas Crockford's excellent JavaScript: The Good Parts,

JavaScript has two sets of equality operators: === and !==, and their evil twins == and !=. The good ones work the way you would expect. If the two operands are of the same type and have the same value, then === produces true and !== produces false. The evil twins do the right thing when the operands are of the same type, but if they are of different types, they attempt to coerce the values. the rules by which they do that are complicated and unmemorable. These are some of the interesting cases:

'' == '0'           // false
0 == ''             // true
0 == '0'            // true

false == 'false'    // false
false == '0'        // true

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

' \t\r\n ' == 0     // true

The lack of transitivity is alarming. My advice is to never use the evil twins. Instead, always use === and !==. All of the comparisons just shown produce false with the === operator.

Update:

A good point was brought up by @Casebash in the comments and in @Phillipe Laybaert's answer concerning objects. For objects, == and === act consistently with one another (except in a special case).

var a = [1,2,3];
var b = [1,2,3];

var c = { x: 1, y: 2 };
var d = { x: 1, y: 2 };

var e = "text";
var f = "te" + "xt";

a == b            // false
a === b           // false

c == d            // false
c === d           // false

e == f            // true
e === f           // true

The special case is when you compare a primitive with an object that evaluates to the same primitive, due to its toString or valueOf method. For example, consider the comparison of a string primitive with a string object created using the String constructor.

"abc" == new String("abc")    // true
"abc" === new String("abc")   // false

Here the == operator is checking the values of the two objects and returning true, but the === is seeing that they're not the same type and returning false. Which one is correct? That really depends on what you're trying to compare. My advice is to bypass the question entirely and just don't use the String constructor to create string objects from string literals.

There are different open source libraries, which you can use for parsing json.

org.json :- If you want to read or write json then you can use this library. First create JsonObject :-

JSONObject jsonObj = new JSONObject(<jsonStr>);

Now, use this object to get your values :-

String id = jsonObj.getString("id");

You can see complete example here

Jackson databind :- If you want to bind and parse your json to particular POJO class, then you can use jackson-databind library, this will bind your json to POJO class :-

ObjectMapper mapper = new ObjectMapper();
post= mapper.readValue(json, Post.class);

You can see complete example here

What about max()

highest = max(1, 2, 3)  # or max([1, 2, 3]) for lists

snippet to retrieve json data, password protected

import requests

username = "my_user_name"
password = "my_super_secret"
url = "https://www.my_base_url.com"
the_page_i_want = "/my_json_data_page"

session = requests.Session()
# retrieve cookie value
resp = session.get(url+'/login')
csrf_token = resp.cookies['csrftoken']
# login, add referer
resp = session.post(url+"/login",
                  data={
                      'username': username,
                      'password': password,
                      'csrfmiddlewaretoken': csrf_token,
                      'next': the_page_i_want,
                  },
                  headers=dict(Referer=url+"/login"))
print(resp.json())

To answer your main question, you want to use the subplot command. I think changing plt.figure(i) to plt.subplot(4,4,i+1) should work.

Using a guid

SELECT @randomString = CONVERT(varchar(255), NEWID())

very short ...

You can use fgets and limit the size of the read string.

char *fgets(char *str, int num, FILE *stream);

You can change the while in your code to:

while (fgets(str, 100, file)) /* printf("%s", str) */;

public void onClick1(View v) {
  DatePickerDialog dialog = new DatePickerDialog(this, this, 2013, 2, 18);
  dialog.show();
}

public void onDateSet1(DatePicker view, int year1, int month1, int day1) {
  e1.setText(day1 + "/" + (month1+1) + "/" + year1);
}

If you want to check if the form data, as it is going to be sent to the server, have changed, you can serialize the form data on page load and compare it to the current form data:

$(function() {

    var form_original_data = $("#myform").serialize(); 

    $("#mybutton").click(function() {
        if ($("#myform").serialize() != form_original_data) {
            // Something changed
        }
    });

});

No, input checkboxes can't be readonly.

But you can make them readonly with javascript!

Add this code anywhere at any time to make checkboxes readonly work as assumed, by preventing the user from modifying it in any way.

jQuery(document).on('click', function(e){_x000D_
      // check for type, avoid selecting the element for performance_x000D_
      if(e.target.type == 'checkbox') {_x000D_
          var el = jQuery(e.target);_x000D_
          if(el.prop('readonly')) {_x000D_
              // prevent it from changing state_x000D_
              e.preventDefault();_x000D_
          }_x000D_
      }_x000D_
});

input[type=checkbox][readonly] {_x000D_
    cursor: not-allowed;_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<label><input type="checkbox" checked readonly> I'm readonly!</label>

You can add this script at any time after jQuery has loaded.

It will work for dynamically added elements.

It works by picking up the click event (that happens before the change event) on any element on the page, it then checks if this element is a readonly checkbox, and if it is, then it blocks the change.

There are so many ifs to make it not affect the performance of the page.

Make sure your \n is in "\n" for it to work.

As I didn't want to break anything, I did this to be able to use newer versions of Python3 than Python v3.4 :

$ sudo update-alternatives --install /usr/local/bin/python3 python3 /usr/bin/python3.6 1
update-alternatives: using /usr/bin/python3.6 to provide /usr/local/bin/python3 (python3) in auto mode
$ sudo update-alternatives --install /usr/local/bin/python3 python3 /usr/bin/python3.7 2

$ update-alternatives --list python3
/usr/bin/python3.6
/usr/bin/python3.7
$ sudo update-alternatives --config python3
There are 2 choices for the alternative python3 (providing /usr/local/bin/python3).

FYI for anyone having this same issue keep in mind that you need to make sure that you have the right version of anaconda in that export path:

anaconda2 or anaconda3 

Spent way too long on that minor issue.

Another way to go about it, besides the nice answers already mentioned, depends upon the fact that you can pass optional named arguments by position. For example,

def f(x,y=None):
    print(x)
    if y is not None:
        print(y)

Yields

In [11]: f(1,2)
1
2

In [12]: f(1)
1

Here's an example of how to create a ColorList programmatically in Kotlin:

val colorList = ColorStateList(
        arrayOf(
                intArrayOf(-android.R.attr.state_enabled),  // Disabled
                intArrayOf(android.R.attr.state_enabled)    // Enabled
        ),
        intArrayOf(
                Color.BLACK,     // The color for the Disabled state
                Color.RED        // The color for the Enabled state
        )
)

Set the colspan attribute to 2.

...but please don't use tables for layout.

As stated already, running your code through the W3C Validator is great but if your page is complex, you still may not know exactly where to find the open div.

I like using tabs to indent my code. It keeps it visually organized so that these issues are easier to find, children, siblings, parents, etc... they'll appear more obvious.

EDIT: Also, I'll use a few HTML comments to mark closing tags in the complex areas. I keep these to a minimum for neatness.

Starting from the decoded base64 data of an OpenSSL rsa-ssh Key, i've been able to guess a format:

The closest validation of my theory i can find it from RFC 4253:

The "ssh-rsa" key format has the following specific encoding:

  string    "ssh-rsa"
  mpint     e
  mpint     n

Here the 'e' and 'n' parameters form the signature key blob.

But it doesn't explain the length prefixes.

Taking the random RSA PUBLIC KEY i found (in the question), and decoding the base64 into hex:

From RFC3447 - Public-Key Cryptography Standards (PKCS) #1: RSA Cryptography Specifications Version 2.1:

A.1.1 RSA public key syntax

An RSA public key should be represented with the ASN.1 type RSAPublicKey:

  RSAPublicKey ::= SEQUENCE {
     modulus           INTEGER,  -- n
     publicExponent    INTEGER   -- e
  }

The fields of type RSAPublicKey have the following meanings:

• modulus is the RSA modulus n.
• publicExponent is the RSA public exponent e.

Using Microsoft's excellent (and the only real) ASN.1 documentation:

30 82 01 0a       ;SEQUENCE (0x010A bytes: 266 bytes)

• exponent = 65,537

Update: My expanded form of this answer in another question

Use empty (it checks both nullness and emptiness) and group the nested ternary expression by parentheses (EL is in certain implementations/versions namely somewhat problematic with nested ternary expressions). Thus, so:

styleClass="#{empty obj.validationErrorMap ? ' ' :  
 (obj.validationErrorMap.contains('key') ? 'highlight_field' : 'highlight_row')}"

If still in vain (I would then check JBoss EL configs), use the "normal" EL approach:

styleClass="#{empty obj.validationErrorMap ? ' ' :  
 (obj.validationErrorMap['key'] ne null ? 'highlight_field' : 'highlight_row')}"

Update: as per the comments, the Map turns out to actually be a List (please work on your naming conventions). To check if a List contains an item the "normal" EL way, use JSTL fn:contains (although not explicitly documented, it works for List as well).

styleClass="#{empty obj.validationErrorMap ? ' ' :  
 (fn:contains(obj.validationErrorMap, 'key') ? 'highlight_field' : 'highlight_row')}"

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'
}

Error from db_connection.java -->> java.sql.SQLException: ORA-00604: error occurred at recursive SQL level 1 ORA-01882: timezone region not found

ORA-00604: error occurred at recursive SQL level 1ORA-01882: timezone region not found

Prev code:

 public Connection getOracle() throws Exception {
     Connection conn = null;
     Class.forName("oracle.jdbc.driver.OracleDriver");
     conn = DriverManager.getConnection("jdbc:oracle:thin:@127.0.0.1:1521:tap", "username", "pw");
     return conn;
}

new Code:

 public Connection getOracle() throws Exception {
     TimeZone timeZone = TimeZone.getTimeZone("Asia/Kolkata");
     TimeZone.setDefault(timeZone);
     Connection conn = null;
     Class.forName("oracle.jdbc.driver.OracleDriver");
     conn = DriverManager.getConnection("jdbc:oracle:thin:@127.0.0.1:1521:tap", "username", "pw");
     return conn;
}

now it is working!!

I prefer coloring by theme

<style name="CustomTheme" parent="android:Theme.Light">
    <item name="android:windowBackground">@color/custom_theme_color</item>
    <item name="android:colorBackground">@color/custom_theme_color</item>
</style>

In docs.python.org Topic = 5.6.2. String Formatting Operations http://docs.python.org/library/stdtypes.html#string-formatting then further down to the chart (text above chart is "The conversion types are:")

The chart lists 16 types and some following notes.

My comment: help does not include attitude which is a bonus. The attitude post enabled me to search further and find the info.

I was facing the same issue but it was not a permission issue.

When you are doing git clone it will create try to create replica of the respository structure.

When its trying to create the folder/directory with same name and path in your local os process is not allowing to do so and hence the error. There was "background" java process running in Task-manager which was accessing the resource of the directory(folder) and hence it was showing as permission denied for git operations. I have killed those process and that solved my problem. Cheers!!

If you have jQuery UI (needed for the datepicker), this would do the trick:

$.datepicker.formatDate('yy/mm/dd', new Date());

To expand upon Mr. Eels comment, you can do it like this:

    File file = new File("C:\\A.txt");
    FileWriter writer;
    try {
        writer = new FileWriter(file, true);
        PrintWriter printer = new PrintWriter(writer);
        printer.append("Sue");
        printer.close();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

Don't say we ain't good to ya!

A conditional insert for use typically in a MySQL script would be:

insert into t1(col1,col2,col3,...)
select val1,val2,val3,...
  from dual
 where [conditional predicate];

You need to use dummy table dual.

In this example, only the second insert-statement will actually insert data into the table:

create table t1(col1 int);
insert into t1(col1) select 1 from dual where 1=0;
insert into t1(col1) select 2 from dual where 1=1;
select * from t1;
+------+
| col1 |
+------+
|    2 |
+------+
1 row in set (0.00 sec)

Is there a reason you couldn't select your results and right click and choose Advanced Copy -> Advanced Copy? I'm on a Mac and this is how I always copy results to the clipboard for pasting.

I also got the same error. May be because of the version of tensorflow. After installing tensorflow 1.4.0, I got relief from the error.

pip install tensorflow==1.4.0

How about this?

SUM(IF(PaymentType = "credit card", totalamount, 0)) AS CreditCardTotal

Do this:

for i in dict.keys():
  dict[i]

Use prop() instead of attr() to set the value of checked. Also use :checkbox in find method instead of input and be specific.

Live Demo

$("#news_list tr").click(function() {
    var ele = $(this).find('input');
    if(ele.is(':checked')){
        ele.prop('checked', false);
        $(this).removeClass('admin_checked');
    }else{
        ele.prop('checked', true);
        $(this).addClass('admin_checked');
    }
});

Use prop instead of attr for properties like checked

As of jQuery 1.6, the .attr() method returns undefined for attributes that have not been set. To retrieve and change DOM properties such as the checked, selected, or disabled state of form elements, use the .prop() method

Ideally you shouldn't be splitting strings in T-SQL at all.

Barring that change, on older versions before SQL Server 2016, create a split function:

CREATE FUNCTION dbo.SplitStrings
(
    @List      nvarchar(max), 
    @Delimiter nvarchar(2)
)
RETURNS TABLE
WITH SCHEMABINDING
AS
  RETURN ( WITH x(x) AS
    (
      SELECT CONVERT(xml, N'<root><i>' 
        + REPLACE(@List, @Delimiter, N'</i><i>') 
        + N'</i></root>')
    )
    SELECT Item = LTRIM(RTRIM(i.i.value(N'.',N'nvarchar(max)')))
      FROM x CROSS APPLY x.nodes(N'//root/i') AS i(i)
  );
GO

Now you can say:

DECLARE @Values varchar(1000);

SET @Values = 'A, B, C';

SELECT blah
  FROM dbo.foo
  INNER JOIN dbo.SplitStrings(@Values, ',') AS s
    ON s.Item = foo.myField;

On SQL Server 2016 or above (or Azure SQL Database), it is much simpler and more efficient, however you do have to manually apply LTRIM() to take away any leading spaces:

DECLARE @Values varchar(1000) = 'A, B, C';

SELECT blah
  FROM dbo.foo
  INNER JOIN STRING_SPLIT(@Values, ',') AS s
    ON LTRIM(s.value) = foo.myField;

Extract the jar, and put it somewhere in your Java project (usually under a "lib" subdirectory).

Right click the project, open its preferences, go for Java build path, and then the Libraries tab. You can add the library there with "add a jar".

If your jar is not open source, you may want to store it elsewhere and connect to it as an external jar.

find / -print will do this

monthly_mean.plot(y='A')

Uses index as x-axis by default.

For more control you can use the replace callback to handle the value.

value = "tags:HUNT  tags:HUNT         tags:HUNT  tags:HUNT"
value.replace(new RegExp(`(?:\\s+)(?:tags)`, 'g'), $1 => ` ${$1.trim()}`)
//"tags:HUNT tags:HUNT tags:HUNT tags:HUNT"

I usually add to index changes I don't want to stash and then stash with --keep-index option.

git add app/controllers/cart_controller.php
git stash --keep-index
git reset

Last step is optional, but usually you want it. It removes changes from index.

Warning As noted in the comments, this puts everything into the stash, both staged and unstaged. The --keep-index just leaves the index alone after the stash is done. This can cause merge conflicts when you later pop the stash.

It is a pointer to a pointer, so yes, in a way it's a 2D character array. In the same way that a char* could indicate an array of chars, a char** could indicate that it points to and array of char*s.

I'm not entirely certain myself, I recall seeing jQuery did it to an extent, but it doesn't handle hierarchical records at all, let alone in a php friendly way.

One thing I do know for certain, is when building URLs and sticking the product into the dom, don't just use string-glue to do it, or you'll be opening yourself to a handy page breaker.

For instance, certain advertising software in-lines the version string from whatever runs your flash. This is fine when its adobes generic simple string, but however, that's very naive, and blows up in an embarrasing mess for people whom have installed Gnash, as gnash'es version string happens to contain a full blown GPL copyright licences, complete with URLs and <a href> tags. Using this in your string-glue advertiser generator, results in the page blowing open and having imbalanced HTML turning up in the dom.

The moral of the story:

   var foo = document.createElement("elementnamehere"); 
   foo.attribute = allUserSpecifiedDataConsideredDangerousHere; 
   somenode.appendChild(foo); 

Not:

   document.write("<elementnamehere attribute=\"" 
        + ilovebrokenwebsites 
        + "\">" 
        + stringdata 
        + "</elementnamehere>");

_{Google need to learn this trick. I tried to report the problem, they appear not to care.}

Download the developer edition. There you can choose Express as license when installing.

Here is a piece of code to do so:

def(StringChallenge(str1)):

#str1 = str1[1:-1]
h1 = 0
h2 = 0
m1 = 0
m2 = 0

def time_dif(h1,m1,h2,m2):
    if(h1 == h2):
        return m2-m1
    else:
        return ((h2-h1-1)*60 + (60-m1) + m2)
count_min = 0

if str1[1] == ':':
    h1=int(str1[:1])
    m1=int(str1[2:4])
else:
    h1=int(str1[:2])
    m1=int(str1[3:5])

if str1[-7] == '-':
    h2=int(str1[-6])
    m2=int(str1[-4:-2])
else:
    h2=int(str1[-7:-5])
    m2=int(str1[-4:-2])

if h1 == 12:
    h1 = 0
if h2 == 12:
    h2 = 0

if "am" in str1[:8]:
    flag1 = 0
else:
    flag1= 1

if "am" in str1[7:]:
    flag2 = 0
else:
    flag2 = 1

if flag1 == flag2:
    if h2 > h1 or (h2 == h1 and m2 >= m1):
        count_min += time_dif(h1,m1,h2,m2)
    else:
        count_min += 1440 - time_dif(h2,m2,h1,m1)
else:
    count_min += (12-h1-1)*60
    count_min += (60 - m1)
    count_min += (h2*60)+m2


return count_min
