My take to describe this in a more accessible way...

In order to understand what Apache Camel is, you need to understand what Enterprise Integration Patterns are.

Let's start with what we presumably already know: The Singleton pattern, the Factory pattern, etc; They are merely ways of organizing your solution to the problem, but they are not solutions themselves. These patterns were analyzed and extracted for the rest of us by the Gang of Four, when they published their book: Design Patterns. They saved some of us tremendous effort in thinking of how to best structure our code.

Much like the Gang of Four, Gregor Hohpe and Bobby Woolf authored the book Enterprise Integration Patterns (EIP) in which they propose and document a set of new patterns and blueprints for how we could best design large component-based systems, where components can be running on the same process or in a different machine.

They basically propose that we structure our system to be message oriented -- where components communicate with each others using messages as inputs and outputs and absolutely nothing else. They show us a complete set of patterns that we may choose from and implement in our different components that will together form the whole system.

So what is Apache Camel?

Apache Camel offers you the interfaces for the EIPs, the base objects, commonly needed implementations, debugging tools, a configuration system, and many other helpers which will save you a ton of time when you want to implement your solution to follow the EIPs.

Take MVC. MVC is pretty simple in theory and we could implement it without any framework help. But good MVC frameworks provide us with the structure ready-to-use and have gone the extra mile and thought out all the other "side" things you need when you create a large MVC project and that's why we use them most of the time.

That's exactly what Apache Camel is for EIPs. It's a complete production-ready framework for people who want to implement their solution to follow the EIPs.

The format for an URI is defined in RFC 3986. See section 3.3 for details.

To resolve by keeping the version in your current branch (ignore the version from the branch you are merging in), just add and commit the file:

git commit -a

To resolve by overwriting the version in your current branch with the version from the branch you are merging in, you need to retrieve that version into your working directory first, and then add/commit it:

git checkout otherbranch theconflictedfile
git commit -a

Explained in more detail

You can use a regular expression: window.location.href.match(/^[^\#\?]+/)[0]

I experienced a similar problem. Initially, adding the GCC bin folder to my system path did not resolve the problem. I found two solutions.

The first was to run a batch file I found in the root of the MinGW install, mingwbuilds.bat. It (apparently) launches a command prompt configured correctly to run GCC. The second was to remove double-quotation marks from the GCC install bin folder that I had added to my user path variable. I tried this after noticing the batch file not using double-quotes around the install bin path.

Extra Details

I found the batch file accidentally while browsing the install folder tree trying to locate the various executables that weren't launching (according to the -v output). I found some information on the MinGW wiki, http://www.mingw.org/wiki/Getting_Started, in the Cautions and Environment Settings sections, that indicates why the MinGW installer does not set up the system or user path to include the install folder. These seem to confirm the batch file is intended to launch a command prompt suitable for running GCC from a Windows prompt.

i suggest you use moment.js for this. In moment.js you can:

var localTime = moment().format('YYYY-MM-DD'); // store localTime
var proposedDate = localTime + "T00:00:00.000Z";

now that you have the right format for a time, parse it if it's valid:

var isValidDate = moment(proposedDate).isValid();
// returns true if valid and false if it is not.

and to get time parts you can do something like:

var momentDate = moment(proposedDate)
var hour = momentDate.hours();
var minutes = momentDate.minutes();
var seconds = momentDate.seconds();

// or you can use `.format`:
console.log(momentDate.format("YYYY-MM-DD hh:mm:ss A Z"));

Lazy loading will produce several SQL calls while Eager loading may load data with one "more heavy" call (with joins/subqueries).

For example, If there is a high ping between your web and sql servers you would go with Eager loading instead of loading related items 1-by-1 with lazy Loading.

You can use this function (I found it here: http://excelribbon.tips.net/T010780_Colors_in_an_IF_Function.html):

Function GetFillColor(Rng As Range) As Long
    GetFillColor = Rng.Interior.ColorIndex
End Function

Here is an explanation, how to create user-defined functions: http://www.wikihow.com/Create-a-User-Defined-Function-in-Microsoft-Excel

In your worksheet, you can use the following: =GetFillColor(B5)

There are several methods of showing a progress bar (circle) while loading an activity. In your case, one with a ListView in it.

IN ACTIONBAR

If you are using an ActionBar, you can call the ProgressBar like this (this could go in your onCreate()

requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS);  
setProgressBarIndeterminateVisibility(true);

And after you are done displaying the list, to hide it.

setProgressBarIndeterminateVisibility(false);

IN THE LAYOUT (The XML)

<LinearLayout
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:layout_weight="1"
    android:orientation="vertical" >

    <LinearLayout
        android:id="@+id/linlaHeaderProgress"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:gravity="center"
        android:orientation="vertical"
        android:visibility="gone" >

        <ProgressBar
            android:id="@+id/pbHeaderProgress"
            style="@style/Spinner"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content" >
        </ProgressBar>
    </LinearLayout>

    <ListView
        android:id="@+id/list"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_weight="1"
        android:cacheColorHint="@android:color/transparent"
        android:divider="#00000000"
        android:dividerHeight="0dp"
        android:fadingEdge="none"
        android:persistentDrawingCache="scrolling"
        android:smoothScrollbar="false" >
    </ListView>
</LinearLayout>

And in your activity (Java) I use an AsyncTask to fetch data for my lists. SO, in the AsyncTask's onPreExecute() I use something like this:

// CAST THE LINEARLAYOUT HOLDING THE MAIN PROGRESS (SPINNER)
LinearLayout linlaHeaderProgress = (LinearLayout) findViewById(R.id.linlaHeaderProgress);

@Override
protected void onPreExecute() {    
    // SHOW THE SPINNER WHILE LOADING FEEDS
    linlaHeaderProgress.setVisibility(View.VISIBLE);
}

and in the onPostExecute(), after setting the adapter to the ListView:

@Override
protected void onPostExecute(Void result) {     
    // SET THE ADAPTER TO THE LISTVIEW
    lv.setAdapter(adapter);

    // CHANGE THE LOADINGMORE STATUS TO PERMIT FETCHING MORE DATA
    loadingMore = false;

    // HIDE THE SPINNER AFTER LOADING FEEDS
    linlaHeaderProgress.setVisibility(View.GONE);
}

EDIT: This is how it looks in my app while loading one of several ListViews

When running the development server - which is what you get by running app.run(), you get a single synchronous process, which means at most 1 request is being processed at a time.

By sticking Gunicorn in front of it in its default configuration and simply increasing the number of --workers, what you get is essentially a number of processes (managed by Gunicorn) that each behave like the app.run() development server. 4 workers == 4 concurrent requests. This is because Gunicorn uses its included sync worker type by default.

It is important to note that Gunicorn also includes asynchronous workers, namely eventlet and gevent (and also tornado, but that's best used with the Tornado framework, it seems). By specifying one of these async workers with the --worker-class flag, what you get is Gunicorn managing a number of async processes, each of which managing its own concurrency. These processes don't use threads, but instead coroutines. Basically, within each process, still only 1 thing can be happening at a time (1 thread), but objects can be 'paused' when they are waiting on external processes to finish (think database queries or waiting on network I/O).

This means, if you're using one of Gunicorn's async workers, each worker can handle many more than a single request at a time. Just how many workers is best depends on the nature of your app, its environment, the hardware it runs on, etc. More details can be found on Gunicorn's design page and notes on how gevent works on its intro page.

I had this problem with XCode 6.3 Below is the steps that worked for me.

Go to XCode > Preferences > Accounts Select your developer account then click View Details... Click on the refresh button on the left bottom of the window. It should notify you that you're missing few certificates. Click Request. XCode automatically should download missing certificates. Click Done and it should work.

simply: document.cookie="name=value;path=/";

There is a negative point to it

Now, the cookie will be available to all directories on the domain it is set from. If the website is just one of many at that domain, it’s best not to do this because everyone else will also have access to your cookie information.

I ended up with this slightly different version:

var dirty = false;
window.onbeforeunload = function() {
    return dirty ? "If you leave this page you will lose your unsaved changes." : null;
}

Elsewhere I set the dirty flag to true when the form gets dirtied (or I otherwise want to prevent navigating away). This allows me to easily control whether or not the user gets the Confirm Navigation prompt.

With the text in the selected answer you see redundant prompts:

I think the simplest method I know follows. MSB is input and LSB is 'reversed' output:

unsigned char rev(char MSB) {
    unsigned char LSB=0;  // for output
    _FOR(i,0,8) {
        LSB= LSB << 1;
        if(MSB&1) LSB = LSB | 1;
        MSB= MSB >> 1;
    }
    return LSB;
}

//    It works by rotating bytes in opposite directions. 
//    Just repeat for each byte.

constructor(private router:Router, private route:ActivatedRoute ) { 
}

onReload(){
 this.router.navigate(['/servers'],{relativeTo:this.route})
}

Well, the documentation does actually state that

CodeIgniter supports "flashdata", or session data that will only be available for the next server request, and are then automatically cleared.

as the very first thing, which obviusly means that you need to do a new server request. A redirect, a refresh, a link or some other mean to send the user to the next request.

Why use flashdata if you are using it in the same request, anyway? You'd might as well not use flashdata or use a regular session.

I don't believe this is possible. The dialog box that gets displayed allows the user to select a printer to print to. So, let's say it would be possible for your application to just click and print, and a user clicks your print button, but has two printers connected to the computer. Or, more likely, that user is working in an office building with 25 printers. Without that dialog box, how would the computer know to which printer to print?

Don't forget buckets are region specific. That might be an issue.

Also try using the S3 console to navigate to the actual object, and then click on Copy Path, you will get something like:

s3://<bucket-name>/<path>/object.txt

As long as whatever you are passing it to parses that properly I find that is the safest thing to do.

I just experienced this issue when outputting to a Windows client. Sure, PHP_EOL is for server side, but most content output from php is for windows clients. So I have to place my findings here for the next person.

A) echo 'My Text' . PHP_EOL; // Bad because this just outputs \n and most versions of windows notepad display this on a single line, and most windows accounting software can't import this type of end of line character.

B) echo 'My Text \r\n'; //Bad because single quoted php strings do not interpret \r\n

C) echo "My Text \r\n"; // Yay it works! Looks correct in notepad, and works when importing the file to other windows software such as windows accounting and windows manufacturing software.

You can just add the padding to tour block element and add background-origin style like so:

.block {
  position: relative;
  display: inline-block;
  padding: 10px 12px;
  border:1px solid #e5e5e5;
  background-size: contain;
  background-position: center;
  background-repeat: no-repeat;
  background-origin: content-box;
  background-image: url(_your_image_);
  height: 14rem;
  width: 10rem;
}

You can check several https://www.w3schools.com/cssref/css3_pr_background-origin.asp

CASE WHEN ', ' + dbo.Table.Column +',' LIKE '%, lactulose,%' 
  THEN 'BP Medication' ELSE '' END AS [BP Medication]

The leading ', ' and trailing ',' are added so that you can handle the match regardless of where it is in the string (first entry, last entry, or anywhere in between).

That said, why are you storing data you want to search on as a comma-separated string? This violates all kinds of forms and best practices. You should consider normalizing your schema.

In addition: don't use 'single quotes' as identifier delimiters; this syntax is deprecated. Use [square brackets] (preferred) or "double quotes" if you must. See "string literals as column aliases" here: http://msdn.microsoft.com/en-us/library/bb510662%28SQL.100%29.aspx

EDIT If you have multiple values, you can do this (you can't short-hand this with the other CASE syntax variant or by using something like IN()):

CASE 
  WHEN ', ' + dbo.Table.Column +',' LIKE '%, lactulose,%' 
  WHEN ', ' + dbo.Table.Column +',' LIKE '%, amlodipine,%' 
  THEN 'BP Medication' ELSE '' END AS [BP Medication]

If you have more values, it might be worthwhile to use a split function, e.g.

USE tempdb;
GO

CREATE FUNCTION dbo.SplitStrings(@List NVARCHAR(MAX))
RETURNS TABLE
AS
   RETURN ( SELECT DISTINCT Item FROM
       ( SELECT Item = x.i.value('(./text())[1]', 'nvarchar(max)')
         FROM ( SELECT [XML] = CONVERT(XML, '<i>'
         + REPLACE(@List,',', '</i><i>') + '</i>').query('.')
           ) AS a CROSS APPLY [XML].nodes('i') AS x(i) ) AS y
       WHERE Item IS NOT NULL
   );
GO

CREATE TABLE dbo.[Table](ID INT, [Column] VARCHAR(255));
GO

INSERT dbo.[Table] VALUES
(1,'lactulose, Lasix (furosemide), oxazepam, propranolol, rabeprazole, sertraline,'),
(2,'lactulite, Lasix (furosemide), lactulose, propranolol, rabeprazole, sertraline,'),
(3,'lactulite, Lasix (furosemide), oxazepam, propranolol, rabeprazole, sertraline,'),
(4,'lactulite, Lasix (furosemide), lactulose, amlodipine, rabeprazole, sertraline,');

SELECT t.ID
  FROM dbo.[Table] AS t
  INNER JOIN dbo.SplitStrings('lactulose,amlodipine') AS s
  ON ', ' + t.[Column] + ',' LIKE '%, ' + s.Item + ',%'
  GROUP BY t.ID;
GO

Results:

ID
----
1
2
4

This worked for me using it in a toolstrip menu:

 private void calculatorToolStripMenuItem_Click(object sender, EventArgs e)
 {
     calculator form = new calculator();
     form.Show(); // or form.ShowDialog(this);
 }

Script snip below creates a pause sub that displayes the pause text in a string and waits for the Enter key. z can be anything. Great if multilple user intervention required pauses are needed. I just keep it in my standard script template.

Pause("Press Enter to continue")

Sub Pause(strPause)
     WScript.Echo (strPause)
     z = WScript.StdIn.Read(1)
End Sub

I guess you are actually using Amazon Linux AMI 2013.03.1 instead of Ubuntu Server 12.x reason why you don't have apt-get tool installed.

Have you check your deploy path in Server Locations? May be your tomcat deploy path changed and Eclipse is not deploying your application.

In eclipse.

1. Window -> Show View -> Servers.
2. Double click to your server.

3. In Tomcat Server's Overview.

   3.1 check your Server Path

   3.2 check your Deploy Path

3 ways to do this:

In C Language (Command Line Tool) Works with Objective C, too:

printf("Hello World");

In Objective C:

NSLog(@"Hello, World!");

In Objective C with variables:

NSString * myString = @"Hello World";
NSLog(@"%@", myString);

In the code with variables, the variable created with class, NSString was outputted be NSLog. The %@ represents text as a variable.

If you use hash paths (like mywebsite.com/#/my/url) which might not refresh frames on switching hash:

<script>
    window.onhashchange = function () {
        window.setTimeout(function () {
            let frame = document.getElementById('myFrame');
            if (frame !== null) {frame.replaceWith(frame);}
        }, 1000);
    }
</script>

Unfortunately, if you don't use the timeout JS may try to replace the frame before the page has finished loading the content (thus loading the old content). I'm not sure of the workaround yet.

1. Both replace() and replaceAll() accepts two arguments and replaces all occurrences of the first substring(first argument) in a string with the second substring (second argument).
2. replace() accepts a pair of char or charsequence and replaceAll() accepts a pair of regex.

3. It is not true that replace() works faster than replaceAll() since both uses the same code in its implementation

   Pattern.compile(regex).matcher(this).replaceAll(replacement);

Now the question is when to use replace and when to use replaceAll(). When you want to replace a substring with another substring regardless of its place of occurrence in the string use replace(). But if you have some particular preference or condition like replace only those substrings at the beginning or end of a string use replaceAll(). Here are some examples to prove my point:

String str = new String("==qwerty==").replaceAll("^==", "?"); \\str: "?qwerty=="
String str = new String("==qwerty==").replaceAll("==$", "?"); \\str: "==qwerty?"
String str = new String("===qwerty==").replaceAll("(=)+", "?"); \\str: "?qwerty?"

Quick Summary

• DataFrame.apply operates on entire rows or columns at a time.

• DataFrame.applymap, Series.apply, and Series.map operate on one element at time.

Series.apply and Series.map are similar and often interchangeable. Some of their slight differences are discussed in osa's answer below.

You can try string.strip()
It worked for me! :)

You could use this script:

def run(runfile):
  with open(runfile,"r") as rnf:
    exec(rnf.read())

Syntax:

run("file.py")

Maximum element value in priceValues[] is maxPriceValues :

double[] priceValues = new double[3];
priceValues [0] = 1;
priceValues [1] = 2;
priceValues [2] = 3;
double maxPriceValues = priceValues.Max();

Grant usage/select to a single table

If you only grant CONNECT to a database, the user can connect but has no other privileges. You have to grant USAGE on namespaces (schemas) and SELECT on tables and views individually like so:

GRANT CONNECT ON DATABASE mydb TO xxx;
-- This assumes you're actually connected to mydb..
GRANT USAGE ON SCHEMA public TO xxx;
GRANT SELECT ON mytable TO xxx;

Multiple tables/views (PostgreSQL 9.0+)

In the latest versions of PostgreSQL, you can grant permissions on all tables/views/etc in the schema using a single command rather than having to type them one by one:

GRANT SELECT ON ALL TABLES IN SCHEMA public TO xxx;

This only affects tables that have already been created. More powerfully, you can automatically have default roles assigned to new objects in future:

ALTER DEFAULT PRIVILEGES IN SCHEMA public
   GRANT SELECT ON TABLES TO xxx;

Note that by default this will only affect objects (tables) created by the user that issued this command: although it can also be set on any role that the issuing user is a member of. However, you don't pick up default privileges for all roles you're a member of when creating new objects... so there's still some faffing around. If you adopt the approach that a database has an owning role, and schema changes are performed as that owning role, then you should assign default privileges to that owning role. IMHO this is all a bit confusing and you may need to experiment to come up with a functional workflow.

Multiple tables/views (PostgreSQL versions before 9.0)

To avoid errors in lengthy, multi-table changes, it is recommended to use the following 'automatic' process to generate the required GRANT SELECT to each table/view:

SELECT 'GRANT SELECT ON ' || relname || ' TO xxx;'
FROM pg_class JOIN pg_namespace ON pg_namespace.oid = pg_class.relnamespace
WHERE nspname = 'public' AND relkind IN ('r', 'v', 'S');

This should output the relevant GRANT commands to GRANT SELECT on all tables, views, and sequences in public, for copy-n-paste love. Naturally, this will only be applied to tables that have already been created.

As the other answers say, use g++ instead of gcc.

Or use make: make hi

To add on to the other answers here, if you would like to create a new object of a third different type with a where clause (e.g. one that is not your Entity Framework object) you can do this:

public IEnumerable<ThirdNonEntityClass> demoMethod(IEnumerable<int> property1Values)
{
    using(var entityFrameworkObjectContext = new EntityFrameworkObjectContext )
    {
        var result = entityFrameworkObjectContext.SomeClass
            .Join(entityFrameworkObjectContext.SomeOtherClass,
                sc => sc.property1,
                soc => soc.property2,
                (sc, soc) => new {sc, soc})
            .Where(s => propertyValues.Any(pvals => pvals == es.sc.property1)
            .Select(s => new ThirdNonEntityClass 
            {
                dataValue1 = s.sc.dataValueA,
                dataValue2 = s.soc.dataValueB
            })
            .ToList();
    }

    return result;

}    

Pay special attention to the intermediate object that is created in the Where and Select clauses.

Note that here we also look for any joined objects that have a property1 that matches one of the ones in the input list.

I know this is a bit more complex than what the original asker was looking for, but hopefully it will help someone.

Also make sure the div is currently appended to the DOM and visible.

Where do these values come from? The documentation for android:fontFamily does not list this information in any place

These are indeed not listed in the documentation. But they are mentioned here under the section 'Font families'. The document lists every new public API for Android Jelly Bean 4.1.

In the styles.xml file in the application I'm working on somebody listed this as the font family, and I'm pretty sure it's wrong:

Yes, that's wrong. You don't reference the font file, you have to use the font name mentioned in the linked document above. In this case it should have been this:

<item name="android:fontFamily">sans-serif</item>

Like the linked answer already stated, 12 variants are possible:

Added in Android Jelly Bean (4.1) - API 16 :

For quick reference, this is how they all look like:

There is also a property resourceRef of JndiObjectFactoryBean that is, when set to true, used to automatically prepend the string java:comp/env/ if it is not already present.

<bean id="someId" class="org.springframework.jndi.JndiObjectFactoryBean">
  <property name="jndiName" value="jdbc/loc"/>
  <property name="resourceRef" value="true"/>
</bean>

To delete bin and obj before build add to project file:

<Target Name="BeforeBuild">
    <!-- Remove obj folder -->
    <RemoveDir Directories="$(BaseIntermediateOutputPath)" />
    <!-- Remove bin folder -->
    <RemoveDir Directories="$(BaseOutputPath)" />
</Target>

Here is article: How to remove bin and/or obj folder before the build or deploy

Everybody else has explained well what is the difference.

I would like to add in Ruby On Rails, it is better to use obj.blank? or obj.present? instead of obj.nil? or obj.empty?.

obj.blank? handles all types nil, '', [], {}, and returns true if values are not available and returns false if values are available on any type of object.

I´ve found a lot of answers here @ stackoverflow.com but definitely this is the correct answer of:

"Sending data from activity to fragment in android".

Activity:

        Bundle bundle = new Bundle();
        String myMessage = "Stackoverflow is cool!";
        bundle.putString("message", myMessage );
        FragmentClass fragInfo = new FragmentClass();
        fragInfo.setArguments(bundle);
        transaction.replace(R.id.fragment_single, fragInfo);
        transaction.commit();

Fragment:

Reading the value in the fragment

        @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        Bundle bundle = this.getArguments();
        String myValue = bundle.getString("message");
        ...
        ...
        ...
        }

or just

        @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        String myValue = this.getArguments().getString("message");
        ...
        ...
        ...
        }

UrlConnection is an awkward API to work with. HttpClient is by far the better API and it'll spare you from loosing time searching how to achieve certain things like this stackoverflow question illustrates perfectly. I write this after having used the jdk HttpUrlConnection in several REST clients. Furthermore when it comes to scalability features (like threadpools, connection pools etc.) HttpClient is superior

Don't do this at the view level. Just set the default value to the property in your view model's constructor. Clean and simple. In your post-backs, your selected value will automatically populate the correct selection.

For example

public class MyViewModel
{
        public MyViewModel()
        {
            Gender = "Male";
        }
}

<table>_x000D_
  <tr>_x000D_
 <td><label>@Html.RadioButtonFor(i => i.Gender, "Male")Male</label></td>_x000D_

While generating the links set the target to the iframes name property and you probably wont have to deal with jquery at all.

<a href="inventory.aspx" target="contentframe"  title="Title Inventory">
<iframe id="iframe1" name="contentframe"  ></iframe>

This is a modified version of Simons answer which makes the multi-lined output a single line. It also introduces the current timestamp so it's easier to follow each line of output.

I used the above to catch slow responses on the above endpoint.

I had the same problem on Win 7. The solution was to remove following files:

1. .hg/store/phaseroots
2. .hg/wlock

As for .hg/store/lock - there was no such file.

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

You can use pandas.Dataframe.isin.

pandas.Dateframe.isin will return boolean values depending on whether each element is inside the list a or not. You then invert this with the ~ to convert True to False and vice versa.

import pandas as pd

a = ['2015-01-01' , '2015-02-01']

df = pd.DataFrame(data={'date':['2015-01-01' , '2015-02-01', '2015-03-01' , '2015-04-01', '2015-05-01' , '2015-06-01']})

print(df)
#         date
#0  2015-01-01
#1  2015-02-01
#2  2015-03-01
#3  2015-04-01
#4  2015-05-01
#5  2015-06-01

df = df[~df['date'].isin(a)]

print(df)
#         date
#2  2015-03-01
#3  2015-04-01
#4  2015-05-01
#5  2015-06-01

$("#YOUR-BUTTON").on('click', function(e) {

});

It's in the python docs.

import datetime
datetime.datetime.combine(datetime.date(2011, 1, 1), 
                          datetime.time(10, 23))

returns

datetime.datetime(2011, 1, 1, 10, 23)

it can do this for case statements as the values are compiler constants. An explanation in more detail is here http://sequence-points.blogspot.com/2007/10/why-is-switch-statement-faster-than-if.html

STRING=(one two three four)
echo "${STRING[n]}"

This problem arise basically when you save your python code in a UTF-8 or UTF-16 encoding because python add some special character at the beginning of the code automatically (which is not shown by the text editors) to identify the encoding format. But, when you try to execute the code it gives you the syntax error in line 1 i.e, start of code because python compiler understands ASCII encoding. when you view the code of file using read() function you can see at the begin of the returned code '\ufeff' is shown. The one simplest solution to this problem is just by changing the encoding back to ASCII encoding(for this you can copy your code to a notepad and save it Remember! choose the ASCII encoding... Hope this will help.

The best way to accomplish that is to use POST which is a method of Hypertext Transfer Protocol https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods

index.php

<html>
<body>

<form action="site2.php" method="post">
Name: <input type="text" name="name">
Email: <input type="text" name="email">
<input type="submit">
</form>

</body>
</html> 

site2.php

 <html>
 <body>

 Hello <?php echo $_POST["name"]; ?>!<br>
 Your mail is <?php echo $_POST["mail"]; ?>.

 </body>
 </html> 

output

Hello "name" !

Your email is "[email protected]" .

You don't need to create the SSH keys on the Jenkins server, nor do you need to store the SSH keys on the Jenkins server's filesystem. This bit of information is crucial in environments where Jenkins servers instances may be created and destroyed frequently.

Generating the SSH Key Pair

On any machine (Windows, Linux, MacOS ...doesn't matter) generate an SSH key pair. Use this article as guide:

• GitHub: Generating a new SSH key and adding it to the ssh-agent (you can skip the section "Adding your SSH key to the ssh-agent")

On the Target Server

On the target server, you will need to place the content of the public key (id_rsa.pub per the above article) into the .ssh/authorized_keys file under the home directory of the user which Jenkins will be using for deployment.

In Jenkins

Using "Publish over SSH" Plugin

Ref: https://plugins.jenkins.io/publish-over-ssh/

Visit: Jenkins > Manage Jenkins > Configure System > Publish over SSH

• If the private key is encrypted, then you will need to enter the passphrase for the key into the "Passphrase" field, otherwise leave it alone.
• Leave the "Path to key" field empty as this will be ignored anyway when you use a pasted key (next step)
• Copy and paste the contents of the private key (id_rsa per the above article) into the "Key" field
• Under "SSH Servers", "Add" a new server configuration for your target server.

Using Stored Global Credentials

Visit: Jenkins > Credentials > System > Global credentials (unrestricted) > Add Credentials

• Kind: "SSH Username with private key"
• Scope: "Global"
• ID: [CREAT A UNIQUE ID FOR THIS KEY]
• Description: [optionally, enter a decription]
• Username: [USERNAME JENKINS WILL USE TO CONNECT TO REMOTE SERVER]
• Private Key: [select "Enter directly"]
• Key: [paste the contents of the private key (id_rsa per the above article)]
• Passphrase: [enter the passphrase for the key, or leave it blank if the key is not encrypted]

I will choose a simple approach using the dplyr package.

If the dataframe is data.

library(dplyr)
result <- filter(data, three == 11)

Maybe can help to check that the path to the xsd file has not 'strange' characters like 'é', or similar: I was having the same issue but when I changed to a path without the 'é' the error dissapeared.

Well, there are plenty of database tutorials online for java (what you're looking for is called JDBC). But if you are using plain servlets, you will have a class that extends HttpServlet and inside it you will have two methods that look like

public void doPost(HttpServletRequest req, HttpServletResponse resp){

}

and

public void doGet(HttpServletRequest req, HttpServletResponse resp){

}

One of them is called to handle GET operations and another is used to handle POST operations. You will then use the HttpServletRequest object to get the parameters that were passed as part of the form like so:

String name = req.getParameter("name");

Then, once you have the data from the form, it's relatively easy to add it to a database using a JDBC tutorial that is widely available on the web. I also suggest searching for a basic Java servlet tutorial to get you started. It's very easy, although there are a number of steps that need to be configured correctly.

The best way I have found to get a feel for things like this is to try them out:

import java.io.File;
public class PathTesting {
    public static void main(String [] args) {
        File f = new File("test/.././file.txt");
        System.out.println(f.getPath());
        System.out.println(f.getAbsolutePath());
        try {
            System.out.println(f.getCanonicalPath());
        }
        catch(Exception e) {}
    }
}

Your output will be something like:

test\..\.\file.txt
C:\projects\sandbox\trunk\test\..\.\file.txt
C:\projects\sandbox\trunk\file.txt

So, getPath() gives you the path based on the File object, which may or may not be relative; getAbsolutePath() gives you an absolute path to the file; and getCanonicalPath() gives you the unique absolute path to the file. Notice that there are a huge number of absolute paths that point to the same file, but only one canonical path.

When to use each? Depends on what you're trying to accomplish, but if you were trying to see if two Files are pointing at the same file on disk, you could compare their canonical paths. Just one example.

You could always construct the #temp table in dynamic SQL. For example, right now I guess you have been trying:

CREATE TABLE #tmp(a INT, b INT, c INT);

DECLARE @sql NVARCHAR(1000);

SET @sql = N'BULK INSERT #tmp ...' + @variables;

EXEC master.sys.sp_executesql @sql;

SELECT * FROM #tmp;

This makes it tougher to maintain (readability) but gets by the scoping issue:

DECLARE @sql NVARCHAR(MAX);

SET @sql = N'CREATE TABLE #tmp(a INT, b INT, c INT);

BULK INSERT #tmp ...' + @variables + ';

SELECT * FROM #tmp;';

EXEC master.sys.sp_executesql @sql;

EDIT 2011-01-12

In light of how my almost 2-year old answer was suddenly deemed incomplete and unacceptable, by someone whose answer was also incomplete, how about:

CREATE TABLE #outer(a INT, b INT, c INT);

DECLARE @sql NVARCHAR(MAX);

SET @sql = N'SET NOCOUNT ON; 

CREATE TABLE #inner(a INT, b INT, c INT);

BULK INSERT #inner ...' + @variables + ';

SELECT * FROM #inner;';

INSERT #outer EXEC master.sys.sp_executesql @sql;

works fine https://maps.google.de/maps?q=51.404989,13.091751&z=17&t=k

You can use #define as an alternative solution, which do not introduce vector and malloc, and you are still using the same syntax when defining an array.

#define row 8
#define col 8

int main()
{
int array_name[row][col];
}

You just need to add [FromUri] before parameter, looks like:

GetCategories([FromUri] int[] categoryIds)

And send request:

/Categories?categoryids=1&categoryids=2&categoryids=3 

First, run the app on simulator. Then, use command+s, or File -> Save Screenshot in Simulator to take necessary and appropriate shots. The screenshots will appear on your desktop by default.

Use cursors.

A cursor can be thought of like a buffered reader, when reading through a document. If you think of each row as a line in a document, then you would read the next line, perform your operations, and then advance the cursor.

@maciej-cygan described the process well, however in order to find your java path:

$ which java

it gives you the path of java binary file which is a linked file in /usr/bin directory. next:

$ cd /usr/bin/ && ls -la | grep java

find the pointed location which is something as follows (for me):

then cd to the pointed directory to find the real home directory for Java. next:

$ ls -la | grep java

which is as follows in this case:

so as it's obvious in the screenshot, my Java home directory is /usr/lib/jvm/java-11-openjdk-amd64. So accordingly I need to add JAVA_HOME to my bash profile (.bashrc, .bash_profile, etc. depending on your OS) like below:

JAVA_HOME="/usr/lib/jvm/java-11-openjdk-amd64"

Here you go!

When you create local variables inside a function that are created on the stack, they most likely get overwritten in memory when exiting the function.

So code like this in most C++ implementations will not work:

char[] populateChar()
{
    char* ch = "wonet return me";
    return ch;
}

A fix is to create the variable that want to be populated outside the function or where you want to use it, and then pass it as a parameter and manipulate the function, example:

void populateChar(char* ch){
    strcpy(ch, "fill me, Will. This will stay", size); // This will work as long as it won't overflow it.
}

int main(){
    char ch[100]; // Reserve memory on the stack outside the function
    populateChar(ch); // Populate the array
}

A C++11 solution using std::move(ch) to cast lvalues to rvalues:

void populateChar(char* && fillme){
    fillme = new char[20];
    strcpy(fillme, "this worked for me");
}

int main(){
    char* ch;
    populateChar(std::move(ch));
    return 0;
}

Or this option in C++11:

char* populateChar(){
    char* ch = "test char";
    // Will change from lvalue to r value
    return std::move(ch);
}

int main(){
    char* ch = populateChar();
    return 0;
}

I will let you decide if it's the fastest or not.

using System;
namespace PrimeNumbers
{

public static class Program
{
    static int primesCount = 0;


    public static void Main()
    {
        DateTime startingTime = DateTime.Now;

        RangePrime(1,1000000);   

        DateTime endingTime = DateTime.Now;

        TimeSpan span = endingTime - startingTime;

        Console.WriteLine("span = {0}", span.TotalSeconds);

    }


    public static void RangePrime(int start, int end)
    {
        for (int i = start; i != end+1; i++)
        {
            bool isPrime = IsPrime(i);
            if(isPrime)
            {
                primesCount++;
                Console.WriteLine("number = {0}", i);
            }
        }
        Console.WriteLine("primes count = {0}",primesCount);
    }



    public static bool IsPrime(int ToCheck)
    {

        if (ToCheck == 2) return true;
        if (ToCheck < 2) return false;


        if (IsOdd(ToCheck))
        {
            for (int i = 3; i <= (ToCheck / 3); i += 2)
            {
                if (ToCheck % i == 0) return false;
            }
            return true;
        }
        else return false; // even numbers(excluding 2) are composite
    }

    public static bool IsOdd(int ToCheck)
    {
        return ((ToCheck % 2 != 0) ? true : false);
    }
}
}

It takes approximately 82 seconds to find and print prime numbers within a range of 1 to 1,000,000, on my Core 2 Duo laptop with a 2.40 GHz processor. And it found 78,498 prime numbers.

git.exe is common for any git based applications like GitHub, Bitbucket etc. Some times it is possible that you have already installed another git based application so git.exe will be present in the bin folder of that application.

For example if you installed bitbucket before github in your PC, you will find git.exe in C:\Users\{username}\AppData\Local\Atlassian\SourceTree\git_local\bin instead of C:\Users\{username}\AppData\Local\GitHub\PortableGit.....\bin.

I tried all of above, nothing worked. What resolved the issue was adding IPv6 bindings in the hosts file. In step 5 of @David Murdochs answer, add two lines instead of one, i.e.:

127.0.0.1 dev.example.com
::1 dev.example.com

I figured it out by checking $ ping localhost from command line, which used to return:

Reply from 127.0.0.1: bytes=32 time<1ms TTL=128

Instead, it now returns:

Reply from ::1: time<1ms

I don't know why, but for some reason IIS Express started using IPv6 instead of IPv4.

-w is the GCC-wide option to disable warning messages.

Using python 64 bit solves lot of problems.

For future reference, webpack 2 removed everything but modules as a way to resolve paths. This means root will not work.

https://gist.github.com/sokra/27b24881210b56bbaff7#resolving-options

The example configuration starts with:

{
  modules: [path.resolve(__dirname, "app"), "node_modules"]
  // (was split into `root`, `modulesDirectories` and `fallback` in the old options)

Another streaming command I've had good results with is piping the ffmpeg output to vlc to create a stream. If you don't have these installed, you can add them:

sudo apt install vlc ffmpeg

In the example I use an mpeg transport stream (ts) over http, instead of rtsp. I've tried both, but the http ts stream seems to work glitch-free on my playback devices.

I'm using a video capture HDMI>USB device that sets itself up on the video4linux2 driver as input. Piping through vlc must be CPU-friendly, because my old dual-core Pentium CPU is able to do the real-time encoding with no dropped frames. I've also had audio-sync issues with some of the other methods, where this method always has perfect audio-sync.

You will have to adjust the command for your device or file. If you're using a file as input, you won't need all that v4l2 and alsa stuff. Here's the ffmpeg|vlc command:

ffmpeg -thread_queue_size 1024 -f video4linux2 -input_format mjpeg -i /dev/video0 -r 30 -f alsa -ac 1 -thread_queue_size 1024 -i hw:1,0 -acodec aac -vcodec libx264 -preset ultrafast -crf 18 -s hd720 -vf format=yuv420p -profile:v main -threads 0 -f mpegts -|vlc -I dummy - --sout='#std{access=http,mux=ts,dst=:8554}'

For example, lets say your server PC IP is 192.168.0.10, then the stream can be played by this command:

ffplay http://192.168.0.10:8554
#or
vlc http://192.168.0.10:8554

If this is for an intranet application and all of the clients use DHCP, you can query the DHCP server for the MAC address for a given IP address.

Use CURRENT_TIMESTAMP() or now()

Like

INSERT INTO servers (server_name, online_status, exchange, disk_space,
network_shares,date_time) VALUES('m1','ONLINE','ONLINE','100GB','ONLINE',now() )

or

INSERT INTO servers (server_name, online_status, exchange, disk_space,
network_shares,date_time) VALUES('m1', 'ONLINE', 'ONLINE', '100GB', 'ONLINE'
,CURRENT_TIMESTAMP() )

Replace date_time with the column name you want to use to insert the time.

Look up \enlargethispage in some LaTeX reference.

UITableView has a property separatorInset. You can use that to set the insets of the table view separators to zero to let them span the full width of the screen.

[tableView setSeparatorInset:UIEdgeInsetsZero];

Note: If your app is also targeting other iOS versions, you should check for the availability of this property before calling it by doing something like this:

if ([tableView respondsToSelector:@selector(setSeparatorInset:)]) {
    [tableView setSeparatorInset:UIEdgeInsetsZero];
}

An abstract class can have a constructor BUT you can not create an object of abstract class so how do you use that constructor?

Thing is when you inherit that abstract class in your subclass you can pass values to its(abstract's) constructor through super(value) method in your subclass and no you don't inherit a constructor.

so using super you can pass values in a constructor of the abstract class and as far as I remember it has to be the first statement in your method or constructor.

Select cell B2 and click "Freeze Panes" this will freeze Row 1 and Column A.

For future reference, selecting Freeze Panes in Excel will freeze the rows above your selected cell and the columns to the left of your selected cell. For example, to freeze rows 1 and 2 and column A, you could select cell B3 and click Freeze Panes. You could also freeze columns A and B and row 1, by selecting cell C2 and clicking "Freeze Panes".

You can't, this is determined by the browser, for the user's safety and security. For example you can't make it say "Virus detected" with a message of "Would you like to quarantine it now?"...at least not as an alert().

There are plenty of JavaScript Modal Dialogs out there though, that are far more customizable than alert().

Check number of open files for the mysql process using lsof command.

Increase the open files limit and run again.

If the problem still persists even after putting the after build in the correct project try using "copy" instead of xcopy. This worked for me.

First you need to create a gradient.xml as follows

<shape>
    <gradient android:angle="270" android:endColor="#181818" android:startColor="#616161" />

    <stroke android:width="1dp" android:color="#343434" />
</shape>

Then you need to mention above gradient in the background of layout.As follows

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="@drawable/gradient"
    >   
</LinearLayout>

libstdc++, which is part of gcc, has a special debug mode for error checking. It is enabled by compiler flag -D_GLIBCXX_DEBUG. Among other things it does bounds checking for std::vector at the cost of performance. Here is online demo with recent version of gcc.

So actually you can do bounds checking with libstdc++ debug mode but you should do it only when testing because it costs notable performance compared to normal libstdc++ mode.

We use a custom provider for multi language support and put all texts in a database table. It works well except we sometimes face caching problems when updating texts in the database without updating the web application.

You should also read about python packages here: http://docs.python.org/tutorial/modules.html.

From your example, I would guess that you really have a package at ~/codez/project. The file __init__.py in a python directory maps a directory into a namespace. If your subdirectories all have an __init__.py file, then you only need to add the base directory to your PYTHONPATH. For example:

PYTHONPATH=$PYTHONPATH:$HOME/adaifotis/project

In addition to testing your PYTHONPATH environment variable, as David explains, you can test it in python like this:

$ python
>>> import project                      # should work if PYTHONPATH set
>>> import sys
>>> for line in sys.path: print line    # print current python path

...

To use video extensions that are MKV. You should use video, not source

For example :

  <!-- mkv -->
  <video width="320" height="240" controls src="assets/animation.mkv"></video>
<!-- mp4 -->
  <video width="320" height="240" controls>
    <source src="assets/animation.mp4" type="video/mp4" />
  </video>

First, copy the script over to Machine B using scp

[user@machineA]$ scp /path/to/script user@machineB:/home/user/path

Then, just run the script

[user@machineA]$ ssh user@machineB "/home/user/path/script"

This will work if you have given executable permission to the script.

        var query = HttpUtility.ParseQueryString(uriBuilder.Query);
        query[paramName] = paramValue;
        uriBuilder.Query = query.ToString();

        return uriBuilder.Uri;
    }
}

I hope this helps!

The document.location is an object that contains properties for the current location.

The href property is one of these properties, containing the complete URL, i.e. all the other properties put together.

Some browsers allow you to assign an URL to the location object and acts as if you assigned it to the href property. Some other browsers are more picky, and requires you to use the href property. Thus, to make the code work in all browsers, you have to use the href property.

Both the window and document objects has a location object. You can set the URL using either window.location.href or document.location.href. However, logically the document.location object should be read-only (as you can't change the URL of a document; changing the URL loads a new document), so to be on the safe side you should rather use window.location.href when you want to set the URL.

You just do an opposite comparison. if Col2 <= 1. This will return a boolean Series with False values for those greater than 1 and True values for the other. If you convert it to an int64 dtype, True becomes 1 and False become 0,

df['Col3'] = (df['Col2'] <= 1).astype(int)

If you want a more general solution, where you can assign any number to Col3 depending on the value of Col2 you should do something like:

df['Col3'] = df['Col2'].map(lambda x: 42 if x > 1 else 55)

Or:

df['Col3'] = 0
condition = df['Col2'] > 1
df.loc[condition, 'Col3'] = 42
df.loc[~condition, 'Col3'] = 55

Android no longer downloading the libraries from the SDK manager, it has to be accessed through Google's Maven repository.

You will have to do something similar to this in your build.gradle file:

allprojects {
    repositories {
        jcenter()
        maven {
            url "https://maven.google.com"
        }
    }
}



dependencies {
    ...
    compile "com.android.support:support-core-utils:27.0.2"
}

Find more details about the setting up process here and about the different support library revisions here.

Unless you're in a specific speed optimization process, I would say use whichever method produces the easiest to read and maintain code.

If an iterator is already setup, like with one of the collection classes, then the foreach is a good easy option. And if it's an integer range you're iterating, then for is probably cleaner.

I actually hit on this problem a week ago. The issue had to do with not using an updated Eclipse version of the Android SDK plugin with the latest version of the SDK. It was a fun problem overall, but it disappeared as soon as I updated it.

I had even updated the AVD images and no luck. Apparently the old plugin cannot see the new image layout or something. This is for version 22.3 of the SDK.

Your plunker is firing off

angular.element(document.getElementById('MyController')).scope().myfunction('test');

Before anything is rendered.

You can verify that by wrapping it in a timeout

setTimeout(function() {
   angular.element(document.getElementById('MyController')).scope().myfunction('test');    
}, 1000);

You also need to acutally add an ID to your div.

<div ng-app='MyModule' ng-controller="MyController" id="MyController">

This is a JQuery code for Preventing Submit

$('form').submit(function (e) {
            if (radioButtonValue !== "0") {
                e.preventDefault();
            }
        });

Use generic types !

  class DataExtraction<T>
{
    DateRangeReport dateRange;
    List<Predicate> predicates;
    List<string> cids;

    public DataExtraction( DateRangeReport dateRange,
                           List<Predicate> predicates,
                           List<string> cids)            

    {
        this.dateRange = dateRange;
        this.predicates = predicates;
        this.cids = cids;
    }
}

And call it like this :

  DataExtraction<AdPerformanceRow> extractor = new DataExtraction<AdPerformanceRow>(dates, predicates , cids);

You're effectively scanning the list once to find the min value, then scanning it again to find the index, you can do both in one go:

from operator import itemgetter
min(enumerate(a), key=itemgetter(1))[0] 

This will give you what you want:

eg2011cleaned <- eg2011[!eg2011$ID %in% bg2011missingFromBeg, ]

The error in your second attempt is because you forgot the ,

In general, for convenience, the specification object[index] subsets columns for a 2d object. If you want to subset rows and keep all columns you have to use the specification object[index_rows, index_columns], while index_cols can be left blank, which will use all columns by default.

However, you still need to include the , to indicate that you want to get a subset of rows instead of a subset of columns.

In this LIVE DEMO i've achieved this by using the :before css selector which seems to work quite nicely.

<div class="myDiv">this is my div with multiple colours. It work's with text too!</div>

I thought i would add this as I feel it could work quite well for a percentage bar/visual level of something.

It also means you're not creating multiple divs if you don't have to, and keeps this page up-to-date

Redirect and Request dispatcher are two different methods to move form one page to another. if we are using redirect to a new page actually a new request is happening from the client side itself to the new page. so we can see the change in the URL. Since redirection is a new request the old request values are not available here.

Try using the success() call back

$http.get('/Documents/DocumentsList/' + caseId).success(function (result) {

});

But now since Documents is an array and not a promise, remove the ()

<li ng-repeat="document in Documents" ng-class="IsFiltered(document.Filtered)"> <span>
           <input type="checkbox" name="docChecked" id="doc_{{document.Id}}" ng-model="document.Filtered" />

Idea from here: http://www.phpknowhow.com/mysql/transactions/

The data URI format is:

data:<headers>;<encoding>,<data>

So, you need only append your data to the "data:image/jpeg;," string:

var your_binary_data = document.body.innerText.replace(/(..)/gim,'%$1'); // parse text data to URI format

window.open('data:image/jpeg;,'+your_binary_data);

Your countLines(String filename) method throws IOException.

You can't use it in a member declaration. You'll need to perform the operation in a main(String[] args) method.

Your main(String[] args) method will get the IOException thrown to it by countLines and it will need to handle or declare it.

Try this to just throw the IOException from main

public class MyClass {
  private int lineCount;
  public static void main(String[] args) throws IOException {
    lineCount = LineCounter.countLines(sFileName);
  }
}

or this to handle it and wrap it in an unchecked IllegalArgumentException:

public class MyClass {
  private int lineCount;
  private String sFileName  = "myfile";
  public static void main(String[] args) throws IOException {
    try {
      lineCount = LineCounter.countLines(sFileName);
     } catch (IOException e) {
       throw new IllegalArgumentException("Unable to load " + sFileName, e);
     }
  }
}

Looks like moment.js is the most popular and with active development:

moment("2010-01-01T05:06:07", moment.ISO_8601);

I would go with Lodash: isBoolean checks whether the passed-in variable is either primitive boolean or Boolean wrapper object and so accounts for all cases.

Per this github comment, one can disable urllib3 request warnings via requests in a 1-liner:

requests.packages.urllib3.disable_warnings()

This will suppress all warnings though, not just InsecureRequest (ie it will also suppress InsecurePlatform etc). In cases where we just want stuff to work, I find the conciseness handy.

Best C# Telnet Lib I've found is called Minimalistic Telnet. Very easy to understand, use and modify. It works great for the Cisco routers I need to configure.

http://www.codeproject.com/KB/IP/MinimalisticTelnet.aspx

crontab command usage

usage:  crontab [-u user] file
        crontab [-u user] [ -e | -l | -r ]
                (default operation is replace, per 1003.2)
        -e      (edit user's crontab)
        -l      (list user's crontab)
        -r      (delete user's crontab)
        -i      (prompt before deleting user's crontab)

So,

$output = shell_exec('crontab -l');
file_put_contents('/tmp/crontab.txt', $output.'* * * * * NEW_CRON'.PHP_EOL);
echo exec('crontab /tmp/crontab.txt');

The above can be used for both create and edit/append provided the user has the adequate file write permission.

To delete jobs:

echo exec('crontab -r');

Also, take note that apache is running as a particular user and that's usually not root, which means the cron jobs can only be changed for the apache user unless given crontab -u privilege to the apache user.

On Fedora 26 and probably many other versions, you may encounter an error after moving your base folder location as described above. This is particularly true if you are moving it to somewhere under /home. This is because SeLinux kicks in and prevents the docker container from running many of its programs from under this location.

The short solution is to remove the --enable-selinux option when you add the -g parameter.

In order to get this working properly on Windows, you need to manually set the path to the JDK (...\jdk1.x.x_xx\bin) in the system environment variables.

If you mark a form element as required="" then novalidate="" does not help.

A way to circumvent the required validation is to disable the element.

As simon marc said, the process is much the same as it is for you or I browsing a website. If you are comfortable with using the Zend framework, there are some easy to follow tutorials to that make life quite easy to set things up. The hardest part of building a restful api is the design of the it, and making it truly restful, think CRUD in database terms.

It could be that you really want an xmlrpc interface or something else similar. What do you want this interface to allow you to do?

--EDIT

Here is where I got started with restful api and Zend Framework. Zend Framework Example

In short don't use Zend rest server, it's obsolete.

Open the Access Database, you will see Table, Query, Report, Module & Macro.
This contains the macros which can be used to invoke common MS-Access actions in a sequence.

For custom VBA macro, press ALT+F11.

Here is a good rule that covers all possible cases: ports, params and etc

/(https?:\/\/(?:[a-z0-9](?:[a-z0-9-]{0,61}[a-z0-9])?\.)+[a-z0-9][a-z0-9-]{0,61}[a-z0-9])(:?\d*)\/?([a-z_\/0-9\-#.]*)\??([a-z_\/0-9\-#=&]*)/g

We can get everything we want by injecting one style rule and by intercepting zoom events:

$(function () {
  if (!(/iPad|iPhone|iPod/.test(navigator.userAgent))) return
  $(document.head).append(
    '<style>*{cursor:pointer;-webkit-tap-highlight-color:rgba(0,0,0,0)}</style>'
  )
  $(window).on('gesturestart touchmove', function (evt) {
    if (evt.originalEvent.scale !== 1) {
      evt.originalEvent.preventDefault()
      document.body.style.transform = 'scale(1)'
    }
  })
})

? Disables pinch zoom.

? Disables double-tap zoom.

? Scroll is not affected.

? Disables tap highlight (which is triggered, on iOS, by the style rule).

NOTICE: Tweak the iOS-detection to your liking. More on that here.

Apologies to lukejackson and Piotr Kowalski, whose answers appear in modified form in the code above.

Either way, when the using block is exited (either by successful completion or by error) it is closed.

Although I think it would be better to organize like this because it's a lot easier to see what is going to happen, even for the new maintenance programmer who will support it later:

{    
    int employeeID = findEmployeeID();    
    try    
    {
        connection.Open();
        SqlCommand command = new SqlCommand("UpdateEmployeeTable", connection);
        command.CommandType = CommandType.StoredProcedure;
        command.Parameters.Add(new SqlParameter("@EmployeeID", employeeID));
        command.CommandTimeout = 5;

        command.ExecuteNonQuery();    
    } 
    catch (Exception) 
    { 
        /*Handle error*/ 
    }
}

thead {
  position: fixed;
  height: 10px; /* This is whatever height you want */
}
  tbody {
  position: fixed;
  margin-top: 10px; /* This has to match the height of thead */
  height: 300px; /* This is whatever height you want */
}

According to spark documentation "where() is an alias for filter()"

filter(condition) Filters rows using the given condition. where() is an alias for filter().

Parameters: condition – a Column of types.BooleanType or a string of SQL expression.

>>> df.filter(df.age > 3).collect()
[Row(age=5, name=u'Bob')]
>>> df.where(df.age == 2).collect()
[Row(age=2, name=u'Alice')]

>>> df.filter("age > 3").collect()
[Row(age=5, name=u'Bob')]
>>> df.where("age = 2").collect()
[Row(age=2, name=u'Alice')]

Or if "NOT EXISTS" are not implemented

SELECT *
FROM   B
WHERE (SELECT count(*)  FROM   A WHERE  A.ID = B.ID) < 1

With props to Rick (second comment down in the blog post mentioned), here's the MSDN article on httpOnlyCookies.

Bottom line is that you just add the following section in your system.web section in your web.config:

<httpCookies domain="" httpOnlyCookies="true|false" requireSSL="true|false" />

This should do the trick

df = data.frame(date=c("2012-02-01", "2012-02-01", "2012-02-02")) 
dow <- function(x) format(as.Date(x), "%A")
df$day <- dow(df$date)
df

#Returns:
        date       day
1 2012-02-01 Wednesday
2 2012-02-01 Wednesday
3 2012-02-02  Thursday

If you have a flash FLA file that shows the FLV movie you can add a button inside the FLA file. This button can be given an action to load the URL.

on (release) {
  getURL("http://someurl/");
}

To make the button transparent you can place a square inside it that is moved to the hit-area frame of the button.

I think it would go too far to explain into depth with pictures how to go about in stackoverflow.

As suggested by Adam Miller in the comments, I'll add another solution.

The MailMessage(String from, String to) constructor accepts a comma separated list of addresses. So if you happen to have already a comma (',') separated list, the usage is as simple as:

MailMessage Msg = new MailMessage(fromMail, addresses);

In this particular case, we can replace the ';' for ',' and still make use of the constructor.

MailMessage Msg = new MailMessage(fromMail, addresses.replace(";", ","));

Whether you prefer this or the accepted answer it's up to you. Arguably the loop makes the intent clearer, but this is shorter and not obscure. But should you already have a comma separated list, I think this is the way to go.

Just to top this up to the new Java 8 API:

DateTimeFormatter formatter = new DateTimeFormatterBuilder().appendPattern("MMMM dd, yyyy").toFormatter();
TemporalAccessor ta = formatter.parse("June 27, 2007");
Instant instant = LocalDate.from(ta).atStartOfDay().atZone(ZoneId.systemDefault()).toInstant();
Date d = Date.from(instant);
assertThat(d.getYear(), is(107));
assertThat(d.getMonth(), is(5));

A bit more verbose but you also see that the methods of Date used are deprecated ;-) Time to move on.

You have no need to put for loop to see the data into the array, you can simply do in following manner

<?php
echo "<pre>";
 print_r($results); 
echo "</pre>";
?>

BULK INSERT dbo.temp 

FROM 'c:\temp\file.txt' --- path file in db server 

WITH 

  (
     ROWTERMINATOR ='\n'
  )

it work for me but save as by editplus to ansi encoding for multilanguage

What do I need to do to make this function wait for the result of the promise?

Use async/await (NOT Part of ECMA6, but available for Chrome, Edge, Firefox and Safari since end of 2017, see canIuse)
MDN

    async function waitForPromise() {
        // let result = await any Promise, like:
        let result = await Promise.resolve('this is a sample promise');
    }

Added due to comment: An async function always returns a Promise, and in TypeScript it would look like:

    async function waitForPromise(): Promise<string> {
        // let result = await any Promise, like:
        let result = await Promise.resolve('this is a sample promise');
    }

[Update]

The original answer was written prior to jQuery 1.3, and the functions that existed at the time where not adequate by themselves to calculate the whole width.

Now, as J-P correctly states, jQuery has the functions outerWidth and outerHeight which include the border and padding by default, and also the margin if the first argument of the function is true

[Original answer]

The width method no longer requires the dimensions plugin, because it has been added to the jQuery Core

What you need to do is get the padding, margin and border width-values of that particular div and add them to the result of the width method

Something like this:

var theDiv = $("#theDiv");
var totalWidth = theDiv.width();
totalWidth += parseInt(theDiv.css("padding-left"), 10) + parseInt(theDiv.css("padding-right"), 10); //Total Padding Width
totalWidth += parseInt(theDiv.css("margin-left"), 10) + parseInt(theDiv.css("margin-right"), 10); //Total Margin Width
totalWidth += parseInt(theDiv.css("borderLeftWidth"), 10) + parseInt(theDiv.css("borderRightWidth"), 10); //Total Border Width

Split into multiple lines to make it more readable

That way you will always get the correct computed value, even if you change the padding or margin values from the css

At runtime, you know what style you want your button to have. So beforehand, in xml in the layout folder, you can have all ready to go buttons with the styles you need. So in the layout folder, you might have a file named: button_style_1.xml. The contents of that file might look like:

<?xml version="1.0" encoding="utf-8"?>
<Button
    android:id="@+id/styleOneButton"
    style="@style/FirstStyle" />

If you are working with fragments, then in onCreateView you inflate that button, like:

Button firstStyleBtn = (Button) inflater.inflate(R.layout.button_style_1, container, false);

where container is the ViewGroup container associated with the onCreateView method you override when creating your fragment.

Need two more such buttons? You create them like this:

Button secondFirstStyleBtn = (Button) inflater.inflate(R.layout.button_style_1, container, false);
Button thirdFirstStyleBtn = (Button) inflater.inflate(R.layout.button_style_1, container, false);

You can customize those buttons:

secondFirstStyleBtn.setText("My Second");
thirdFirstStyleBtn.setText("My Third");

Then you add your customized, stylized buttons to the layout container you also inflated in the onCreateView method:

_stylizedButtonsContainer = (LinearLayout) rootView.findViewById(R.id.stylizedButtonsContainer);

_stylizedButtonsContainer.addView(firstStyleBtn);
_stylizedButtonsContainer.addView(secondFirstStyleBtn);
_stylizedButtonsContainer.addView(thirdFirstStyleBtn);

And that's how you can dynamically work with stylized buttons.

Similar to other syntax above but for learning - can you sort by column names?

sort(colnames(test[1:ncol(test)] ))

Simple method to get resource ID:

public int getDrawableName(Context ctx,String str){
    return ctx.getResources().getIdentifier(str,"drawable",ctx.getPackageName());
}

Will it work for you ?

class MyClass;
typedef std::pair<int,MyClass> MyPair;
class MyClass
{
  private:
  void foo() const{};
public:
static void Method(MyPair const& p) 
{
    //......
        p.second.foo();
};
}; 
// ...
std::map<int, MyClass> Map;
//.....
std::for_each(Map.begin(), Map.end(), (&MyClass::Method));

Previous versions of Angular (pre 1.0 RC) allowed you to use this interchangeably with the $scope method, but this is no longer the case. Inside of methods defined on the scope this and $scope are interchangeable (angular sets this to $scope), but not otherwise inside your controller constructor.

To bring back this behaviour (does anyone know why was it changed?) you can add:

return angular.extend($scope, this);

at the end of your controller function (provided that $scope was injected to this controller function).

This has a nice effect of having access to parent scope via controller object that you can get in child with require: '^myParentDirective'

the error can be due to one of several missing package. Below command will install several packages like g++, gcc, etc.

sudo apt-get install build-essential

See this two links:

So I decided to look at the java source code because I found official docs a bit confusing. And what I found (for OpenJDK 11) mostly aligns with what others have written. What is important is the order of evaluation of properties.

InetAddressCachePolicy.java (I'm omitting some boilerplate for readability):

String tmpString = Security.getProperty("networkaddress.cache.ttl");
if (tmpString != null) {
   tmp = Integer.valueOf(tmpString);
   return;
}
...
String tmpString = System.getProperty("sun.net.inetaddr.ttl");
if (tmpString != null) {
   tmp = Integer.valueOf(tmpString);
   return;
}
...
if (tmp != null) {
  cachePolicy = tmp < 0 ? FOREVER : tmp;
  propertySet = true;
} else {
  /* No properties defined for positive caching. If there is no
  * security manager then use the default positive cache value.
  */
  if (System.getSecurityManager() == null) {
    cachePolicy = 30;
  }
}

You can clearly see that the security property is evaluated first, system property second and if any of them is set cachePolicy value is set to that number or -1 (FOREVER) if they hold a value that is bellow -1. If nothing is set it defaults to 30 seconds. As it turns out for OpenJDK that is almost always the case because by default java.security does not set that value, only a negative one.

#networkaddress.cache.ttl=-1 <- this line is commented out
networkaddress.cache.negative.ttl=10

BTW if the networkaddress.cache.negative.ttl is not set (removed from the file) the default inside the java class is 0. Documentation is wrong in this regard. This is what tripped me over.

You can also throw exceptions as documented here: http://blogs.msdn.com/b/youssefm/archive/2012/06/28/error-handling-in-asp-net-webapi.aspx

Note, to do what that article suggests, remember to include System.Net.Http

var num = 34.7654;

num = Math.round(num * 10) / 10;

console.log(num); // Logs: 34.8

Please see this link for more information on setting the text size in code. Basically it says:

public void setTextSize (int unit, float size)

Since: API Level 1 Set the default text size to a given unit and value. See TypedValue for the possible dimension units. Related XML Attributes

unit The desired dimension unit.
size The desired size in the given units.

Novice mistake. Make sure your package.json file is coded correctly. I had:

"start": "index node.js"
instead of:
"start": "node index.js"

Delete your package-lock.json file and node_modules folder. Then do npm cache clean

npm cache clean --force do npm install

Another way of doing this: new_df = A_df.merge(B_df, left_on=['A_c1','c2'], right_on = ['B_c1','c2'], how='left')

python now points to python3, if you need python 2 then do: brew install python@2 and then in your .zshrc or .bashrc file export PATH="/usr/local/opt/python@2/libexec/bin:$PATH" Now, pyhon --version = Python 2.7.14 and python3 --version = Python 3.6.4. That's the behavior I'm used to seeing in my terminal.

You must allow for more than a digit (the + sign) as in:

String regex = "[0-9]+"; 
String data = "23343453"; 
System.out.println(data.matches(regex));

Open a terminal and type: java -version, or javac -version.

If you have all the latest updates for Snow Leopard, you should be running JDK 1.6.0_20 at this moment (the same as Oracle's current JDK version).

Batch files can be run on Linux. This article explains how (http://www.linux.org/threads/running-windows-batch-files-on-linux.7610/).

or

coord_cartesian(xlim = c(-5000, 5000)) 

Where the first removes all data points outside the given range and the second only adjusts the visible area. In most cases you would not see the difference, but if you fit anything to the data it would probably change the fitted values.

You can also use the shorthand function xlim (or ylim), which like the first option removes data points outside of the given range:

+ xlim(-5000, 5000)

For more information check the description of coord_cartesian.

The RStudio cheatsheet for ggplot2 makes this quite clear visually. Here is a small section of that cheatsheet:

Depending on your use of Google Analytics data, if you want basic information (such as visits, UI interactions) you might be able to not include analytics.js at all, yet still collect data in GA.

One option may be to instead use the measurement protocol in a cached script. Google Analytics: Measurement Protocol Overview

When you set the transport method explicitly to image, you can see how GA constructs its own image beacons.

ga('set', 'transport', 'image');

https://www.google-analytics.com/r/collect
  ?v={protocol-version}
  &tid={tracking-id}
  &cid={client-id}
  &t={hit-type}
  &dl={location}

You could create your own GET or POST requests with the required payload.

However, if you require a greater level of detail it probably won't be worth your effort.

The technique I use frequently to simulate a random connection timeout is to use ssh local port forwarding.

ssh -L 12345:realserver.com:80 localhost

This will forward traffic on localhost:12345 to realserver.com:80 You can loop this around in your own local machine as well, if you want:

ssh -L 12345:localhost:8080 localhost

So you can point your application at your localhost and custom port, and the traffic will get routed to the target host:port. Then you can exit out of this shell (you may also need to ctrl+c the shell after you exit) and it will kill the forwarding which causes your app to see a connection loss.

For Python3:

a, b = list(map(str, input().split()))
v = int(b)

Or it could be that Skype is running on the same port (it does by default).

Disable Skype or configure Skype to use another port

Never recommended to mutate the state directly.

The recommended approach in later React versions is to use an updater function when modifying states to prevent race conditions:

Push string to end of the array

this.setState(prevState => ({
  myArray: [...prevState.myArray, "new value"]
}))

Push string to beginning of the array

this.setState(prevState => ({
  myArray: ["new value", ...prevState.myArray]
}))

Push object to end of the array

this.setState(prevState => ({
  myArray: [...prevState.myArray, {"name": "object"}]
}))

Push object to beginning of the array

this.setState(prevState => ({
  myArray: [ {"name": "object"}, ...prevState.myArray]
}))

Pure CSS approaches that work very well are discussed here. Two techniques are examined in particular and I personally prefer the second as it not CSS3 dependent, which suits my own needs better.

If most/all of your traffic has a CSS3 capable browser, the first method is quicker and cleaner to implement (copy/pasted by Mr. Zoidberg in another answer here for convenience, though I'd visit the source for further background on why it works).

An alternative method to CSS is to use the JavaScript library jQuery to detect resolution changes and adjust the image size accordingly. This article covers the jQuery technique and provides a live demo.

Supersized is a dedicated JavaScript library designed for static full screen images as well as full sized slideshows.

A good tip for full-screen images is to scale them with a correct ratio beforehand. I normally aim for a size of 1500x1000 when using supersized.js or 1680x1050 for other methods, setting the jpg quality for photographs to between 60-80% resulting in a file size in the region of 100kb or less if possible without compromising quality too much.

Short answer:

use a non-blocking recv(), or a blocking recv() / select() with a very short timeout.

Long answer:

The way to handle socket connections is to read or write as you need to, and be prepared to handle connection errors.

TCP distinguishes between 3 forms of "dropping" a connection: timeout, reset, close.

Of these, the timeout can not really be detected, TCP might only tell you the time has not expired yet. But even if it told you that, the time might still expire right after.

Also remember that using shutdown() either you or your peer (the other end of the connection) may close only the incoming byte stream, and keep the outgoing byte stream running, or close the outgoing stream and keep the incoming one running.

So strictly speaking, you want to check if the read stream is closed, or if the write stream is closed, or if both are closed.

Even if the connection was "dropped", you should still be able to read any data that is still in the network buffer. Only after the buffer is empty will you receive a disconnect from recv().

Checking if the connection was dropped is like asking "what will I receive after reading all data that is currently buffered ?" To find that out, you just have to read all data that is currently bufferred.

I can see how "reading all buffered data", to get to the end of it, might be a problem for some people, that still think of recv() as a blocking function. With a blocking recv(), "checking" for a read when the buffer is already empty will block, which defeats the purpose of "checking".

In my opinion any function that is documented to potentially block the entire process indefinitely is a design flaw, but I guess it is still there for historical reasons, from when using a socket just like a regular file descriptor was a cool idea.

What you can do is:

• set the socket to non-blocking mode, but than you get a system-depended error to indicate the receive buffer is empty, or the send buffer is full
• stick to blocking mode but set a very short socket timeout. This will allow you to "ping" or "check" the socket with recv(), pretty much what you want to do
• use select() call or asyncore module with a very short timeout. Error reporting is still system-specific.

For the write part of the problem, keeping the read buffers empty pretty much covers it. You will discover a connection "dropped" after a non-blocking read attempt, and you may choose to stop sending anything after a read returns a closed channel.

I guess the only way to be sure your sent data has reached the other end (and is not still in the send buffer) is either:

• receive a proper response on the same socket for the exact message that you sent. Basically you are using the higher level protocol to provide confirmation.
• perform a successful shutdow() and close() on the socket

The python socket howto says send() will return 0 bytes written if channel is closed. You may use a non-blocking or a timeout socket.send() and if it returns 0 you can no longer send data on that socket. But if it returns non-zero, you have already sent something, good luck with that :)

Also here I have not considered OOB (out-of-band) socket data here as a means to approach your problem, but I think OOB was not what you meant.

Pure CSS Workaround:

I was using both bootstrap and jQuery UI and changing the order of adding the scripts broke some other objects. I ended up using pure CSS workaround:

.ui-dialog-titlebar-close {
  background: url("http://code.jquery.com/ui/1.10.3/themes/smoothness/images/ui-icons_888888_256x240.png") repeat scroll -93px -128px rgba(0, 0, 0, 0);
  border: medium none;
}
.ui-dialog-titlebar-close:hover {
  background: url("http://code.jquery.com/ui/1.10.3/themes/smoothness/images/ui-icons_222222_256x240.png") repeat scroll -93px -128px rgba(0, 0, 0, 0);
}

function getDialogButton( jqUIdialog, button_names )
{
    if (typeof button_names == 'string')
        button_names = [button_names];
    var buttons = jqUIdialog.parent().find('.ui-dialog-buttonpane button');
    for (var i = 0; i < buttons.length; i++)
    {
        var jButton = $( buttons[i] );
        for (var j = 0; j < button_names.length; j++)
            if ( jButton.text() == button_names[j] )
                return jButton;
    }

    return null;
}

function enableDialogButton( jqUIdialog, button_names, enable )
{
    var button = getDialogButton( jqUIdialog, button_names );
    if (button == null)
        alert('button not found: '+button_names);
    else
    {
        if (enable)
            button.removeAttr('disabled').removeClass( 'ui-state-disabled' );
        else
            button.attr('disabled', 'disabled').addClass( 'ui-state-disabled' );
    }
}

Could this be the solution?

  public static function isArrayAssociative(array $array) {
      reset($array);
      return !is_int(key($array));
  }

The caveat is obviously that the array cursor is reset but I'd say probably the function is used before the array is even traversed or used.

Use jackson library and @ResponseBody annotation on return type for the Controller.

This works if you wish to return POJOs represented as JSon. If you woud like to return String and not POJOs as JSon please refer to Sotirious answer.

The second parameter is selected, so use the ! to select the no value when the boolean is false.

<%= Html.RadioButton("blah", !Model.blah) %> Yes 
<%= Html.RadioButton("blah", Model.blah) %> No 

Try this

    .item img{
      max-height: 300px;
      margin: auto;
    }

Sure. In this case, you'd just do:

length_key = len(d['key'])  # length of the list stored at `'key'` ...

It's hard to say why you actually want this, but, perhaps it would be useful to create another dict that maps the keys to the length of values:

length_dict = {key: len(value) for key, value in d.items()}
length_key = length_dict['key']  # length of the list stored at `'key'` ...

<?php
  $url = 'http://user:[email protected]/path?argument=value#anchor';
  $array=parse_url($url);
  $array['host']=explode('.', $array['host']);

  echo $array['host'][0]; // returns 'en'
?>

     mynumber = mynumbersplit[0];

  }

      var  mn = mynumber.length;

      if (mn <= 3) { return mynumber + numberend; }
      var grps = [];

        while (mn > 3)
        {  
            grps.push(mynumber.substring(mn,mn - 3));
            mn = mn - 3;
        }
        grps.push(mynumber.substring(mn,mn - 3));
      grps.reverse();

        grps.join(",");
        if(numberend!=""){ grps =  grps +"."+numberend;}

        return grps; 
              }

You seem a bit confused as to how numpy arrays work behind the scenes. Each item in an array must be the same size.

The string representation of a float doesn't work this way. For example, repr(1.3) yields '1.3', but repr(1.33) yields '1.3300000000000001'.

A accurate string representation of a floating point number produces a variable length string.

Because numpy arrays consist of elements that are all the same size, numpy requires you to specify the length of the strings within the array when you're using string arrays.

If you use x.astype('str'), it will always convert things to an array of strings of length 1.

For example, using x = np.array(1.344566), x.astype('str') yields '1'!

You need to be more explict and use the '|Sx' dtype syntax, where x is the length of the string for each element of the array.

For example, use x.astype('|S10') to convert the array to strings of length 10.

Even better, just avoid using numpy arrays of strings altogether. It's usually a bad idea, and there's no reason I can see from your description of your problem to use them in the first place...

I tried to edit the answer provided by marc_s however it wasn't accepted for some reason. It formats the sql for easier reading, includes the schema and also names the Default name so that this can easily be pasted into other code.

For anyone else that may encounter this problem and it is not solved by either of the options above, this is what worked for me.

1. Click on the website in IIS
2. Double Click on Authentication under IIS
3. Enable Anonymous Authentication

I had disabled this because we were using our own Auth, but that lead to this same problem and the accepted answer did not help in any way.

PHP-FPM is a service that spawns new PHP processes when needed, usually through a fast-cgi module like nginx. You can tell (with a margin of error) by just checking the init.d script e.g. "sudo /etc/init.d/php-fpm status"

What port or unix file socket is being used is up to the configuration, but often is just TCP port 9000. i.e. 127.0.0.1:9000

The best way to tell if it is running correctly is to have nginx running, and setup a virtual host that will fast-cgi pass to PHP-FPM, and just check it with wget or a browser.

Answering the question "given two lists, find all possible permutations of pairs of one item from each list" and using basic Python functionality (i.e., without itertools) and, hence, making it easy to replicate for other programming languages:

def rec(a, b, ll, size):
    ret = []
    for i,e in enumerate(a):
        for j,f in enumerate(b):
            l = [e+f]
            new_l = rec(a[i+1:], b[:j]+b[j+1:], ll, size)
            if not new_l:
                ret.append(l)
            for k in new_l:
                l_k = l + k
                ret.append(l_k)
                if len(l_k) == size:
                    ll.append(l_k)
    return ret

a = ['a','b','c']
b = ['1','2']
ll = []
rec(a,b,ll, min(len(a),len(b)))
print(ll)

Returns

[['a1', 'b2'], ['a1', 'c2'], ['a2', 'b1'], ['a2', 'c1'], ['b1', 'c2'], ['b2', 'c1']]

I would use the following approach:

=SUBSTITUTE(LEFT(A2,LEN(A2)-X),"_","-")

where X denotes the length of things you're not after. And, for X I'd use

(ISERROR(FIND("_S",A2,1))*2)+
(ISERROR(FIND("_40K",A2,1))*4)+
(ISERROR(FIND("_60K",A2,1))*4)+
(ISERROR(FIND("_AB",A2,1))*3)+
(ISERROR(FIND("_CD",A2,1))*3)+
(ISERROR(FIND("_EF",A2,1))*3)

The above ISERROR(FIND("X",.,.))*x will return 0 if X is not found and x (the length of X) if it is found. So technically you're trimming A2 from the right with possible matches.

The advantage of this approach above the other mentioned is that it's more apparent what substitution (or removal) is taking place, since the "substitution" is not nested.

Forking creates an entirely new repository from existing repository (simply doing git clone on gitHub/bitbucket)

Forks are best used: when the intent of the ‘split’ is to create a logically independent project, which may never reunite with its parent.

Branch strategy creates a new branch over the existing/working repository

Branches are best used: when they are created as temporary places to work through a feature, with the intent to merge the branch with the origin.

More Specific :- In open source projects it is the owner of the repository who decides who can push to the repository. However, the idea of open source is that everybody can contribute to the project.

This problem is solved by forks: any time a developer wants to change something in an open source project, they don’t clone the official repository directly. Instead, they fork it to create a copy. When the work is finished, they make a pull request so that the owner of the repository can review the changes and decide whether to merge them to his project.

At its core forking is similar to feature branching, but instead of creating branches a fork of the repository is made, and instead of doing a merge request you create a pull request.

The below links provide the difference in a well-explained manner :

As we read in the previous comments this error is occurring because the current SDK version is incompatible with the newest Java versions: 9 and 10.

So, to solve it, you can downgrade your java version to Java 8, or as a workaround, you can export the following option on your terminal:

Linux:

export JAVA_OPTS='-XX:+IgnoreUnrecognizedVMOptions --add-modules java.se.ee'

Windows:

set JAVA_OPTS=-XX:+IgnoreUnrecognizedVMOptions --add-modules java.se.ee'

If this does not work try to exports the java.xml.bind instead.

Linux:

export JAVA_OPTS='-XX:+IgnoreUnrecognizedVMOptions --add-modules java.xml.bind'

Windows:

set JAVA_OPTS=-XX:+IgnoreUnrecognizedVMOptions --add-modules java.xml.bind'

This will solve this error for the sdkmanager

And to make it saved permanently you can export the JAVA_OPTS in your profile file on Linux (.zshrc, .bashrc and etc.) or add it as an environment variable permanently on Windows.

ps. This doesn't work for Java 11/11+, which doesn't have Java EE modules. For this option is a good idea, downgrade your Java version or wait for a Flutter update.

Ref: JDK 11: End of the road for Java EE modules

See Python 3.x format string syntax:

IDLE 3.5.1   
numbers = ['23.23', '.1233', '1', '4.223', '9887.2']

for x in numbers:  
    print('{0: >#016.4f}'. format(float(x)))  

     23.2300
      0.1233
      1.0000
      4.2230
   9887.2000

To define a global variable which is based off a DOM element a few things must be checked. First, if the code is in the <head> section, then the DOM will not loaded on execution. In this case, an event handler must be placed in order to set the variable after the DOM has been loaded, like this:

var systemStatus;
window.onload = function(){ systemStatus = document.getElementById("system_status"); };

However, if this script is inline in the page as the DOM loads, then it can be done as long as the DOM element in question has loaded above where the script is located. This is because javascript executes synchronously. This would be valid:

<div id="system_status"></div>
<script type="text/javascript">
 var systemStatus = document.getElementById("system_status");
</script>

As a result of the latter example, most pages which run scripts in the body save them until the very end of the document. This will allow the page to load, and then the javascript to execute which in most cases causes a visually faster rendering of the DOM.

Just add position, right and top to your class .close-image

.close-image {
    cursor: pointer;
    display: block;
    float: right;  
    z-index: 3;
    position: absolute; /*newly added*/
    right: 5px; /*newly added*/
    top: 5px;/*newly added*/
}

If I understand your questions correctly, all you need to do is add the .Where(m => m.r.u.UserId == 1):

    var UserInRole = db.UserProfiles.
        Join(db.UsersInRoles, u => u.UserId, uir => uir.UserId,
        (u, uir) => new { u, uir }).
        Join(db.Roles, r => r.uir.RoleId, ro => ro.RoleId, (r, ro) => new { r, ro })
        .Where(m => m.r.u.UserId == 1)
        .Select (m => new AddUserToRole
        {
            UserName = m.r.u.UserName,
            RoleName = m.ro.RoleName
        });

Hope that helps.

char arr[3] = "bo";

The arr takes the memory into the stack segment. which will be automatically free, if arr goes out of scope.

The matrix you pasted

[[   1,    8,   50],
 [   8,   64,  400],
 [  50,  400, 2500]]

Has a determinant of zero. This is the definition of a Singular matrix (one for which an inverse does not exist)

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

Like this:

 dataGridView1.Columns[0].Name = "column2";
 dataGridView1.Columns[1].Name = "column6";

 string[] row1 = new string[] { "column2 value", "column6 value" };
 dataGridView1.Rows.Add(row1);

Or you need to set there values individually use the propery .Rows(), like this:

 dataGridView1.Rows[1].Cells[0].Value = "cell value";

The issue for me was that I was doing $.ajax with dataType: "json" for a POST request that was returning an HTTP 201 (created) and no request body. The fix was to simply remove that key/value.

You can use defaultdict in collections.

An example from doc:

s = [('yellow', 1), ('blue', 2), ('yellow', 3), ('blue', 4), ('red', 1)]
d = defaultdict(list)
for k, v in s:
    d[k].append(v)

Go simply with Zoo, it will simply replace all NA values with mean of the column values:

library(zoo)
na.aggregate(data) 

I figured out why the portrait view wasn't totally filling the viewport. At least in my case, it was because the scrollbar was always showing. In addition to the viewport code above, try adding this:

    browser.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY);
    browser.setScrollbarFadingEnabled(false);

This causes the scrollbar to not take up layout space, and allows the webpage to fill the viewport.

Hope this helps

May use

$('<input type="file" />').click()

To mark as obsolete with a warning:

[Obsolete]
private static void SomeMethod()

You get a warning when you use it:

And with IntelliSense:

If you want a message:

[Obsolete("My message")]
private static void SomeMethod()

Here's the IntelliSense tool tip:

Finally if you want the usage to be flagged as an error:

[Obsolete("My message", true)]
private static void SomeMethod()

When used this is what you get:

Note: Use the message to tell people what they should use instead, not why it is obsolete.

This would use less memory, but probably take longer

int count = 0;
string line;
TextReader reader = new StreamReader("file.txt");
while ((line = reader.ReadLine()) != null)
{
  count++;
}
reader.Close();

This is because your row variable/tuple does not contain any value for that index. You can try printing the whole list like print(row) and check how many indexes there exists.

There are two primary contenders for python apps on Android

Chaquopy

https://chaquo.com/chaquopy/

This integrates with the Android build system, it provides a Python API for all android features. To quote the site "The complete Android API and user interface toolkit are directly at your disposal."

Beeware (Toga widget toolkit)

https://pybee.org/

This provides a multi target transpiler, supports many targets such as Android and iOS. It uses a generic widget toolkit (toga) that maps to the host interface calls.

Which One?

Both are active projects and their github accounts shows a fair amount of recent activity.

Beeware Toga like all widget libraries is good for getting the basics out to multiple platforms. If you have basic designs, and a desire to expand to other platforms this should work out well for you.

On the other hand, Chaquopy is a much more precise in its mapping of the python API to Android. It also allows you to mix in Java, useful if you want to use existing code from other resources. If you have strict design targets, and predominantly want to target Android this is a much better resource.

Another solution:

public class CountryInfoResponse {
  private List<Object> geonames;
}

Usage of a generic Object-List solved my problem, as there were other Datatypes like Boolean too.

You need to do encode on tmp[0], not on tmp.

tmp is not a string. It contains a (Unicode) string.

Try running type(tmp) and print dir(tmp) to see it for yourself.

The simplest way might be:

var func='myDynamicFunction_'+myHandler;
var arg1 = 100, arg2 = 'abc';

window[func].apply(null,[arg1, arg2]);

Assuming, that target function is already attached to a "window" object.
