I know this is quite an old post, but I would like to point out the following for people who will read it in the future: As per MS:

Do not use the IISReset.exe tool to restart the IIS services. Instead, use the NET STOP and NET START commands. For example, to stop and start the World Wide Web Publishing Service, run the following commands:

• NET STOP iisadmin /y
• NET START w3svc

There are two benefits to using the NET STOP/NET START commands to restart the IIS Services as opposed to using the IISReset.exe tool. First, it is possible for IIS configuration changes that are in the process of being saved when the IISReset.exe command is run to be lost. Second, using IISReset.exe can make it difficult to identify which dependent service or services failed to stop when this problem occurs. Using the NET STOP commands to stop each individual dependent service will allow you to identify which service fails to stop, so you can then troubleshoot its failure accordingly.

I had the same problem. Following worked for me

Go to the web application --> Properties --> Silverlight Applications

If you don't see you Silverlight application in the list there then click Add and select your Silverlight Application from "Project" dropdown and Add it.

Application Pool recycling restarts the w3wp.exe process for that application pool, hence it will only affect web sites running in that application pool.

IISReset restarts ALL w3wp.exe processes and any other IIS related service, i.e. the NNTP or FTP Service.

I think changing web.config or /bin does not recycle the whole application pool, but I'm not sure on that.

I'm using a helper function to create what I call a "flat promise" -

function flatPromise() {

    let resolve, reject;

    const promise = new Promise((res, rej) => {
      resolve = res;
      reject = rej;
    });

    return { promise, resolve, reject };
}

And I'm using it like so -

function doSomethingAsync() {

    // Get your promise and callbacks
    const { resolve, reject, promise } = flatPromise();

    // Do something amazing...
    setTimeout(() => {
        resolve('done!');
    }, 500);

    // Pass your promise to the world
    return promise;

}

See full working example -

function flatPromise() {_x000D_
_x000D_
    let resolve, reject;_x000D_
_x000D_
    const promise = new Promise((res, rej) => {_x000D_
        resolve = res;_x000D_
        reject = rej;_x000D_
    });_x000D_
_x000D_
    return { promise, resolve, reject };_x000D_
}_x000D_
_x000D_
function doSomethingAsync() {_x000D_
    _x000D_
    // Get your promise and callbacks_x000D_
    const { resolve, reject, promise } = flatPromise();_x000D_
_x000D_
    // Do something amazing..._x000D_
    setTimeout(() => {_x000D_
        resolve('done!');_x000D_
    }, 500);_x000D_
_x000D_
    // Pass your promise to the world_x000D_
    return promise;_x000D_
}_x000D_
_x000D_
(async function run() {_x000D_
_x000D_
    const result = await doSomethingAsync()_x000D_
        .catch(err => console.error('rejected with', err));_x000D_
    console.log(result);_x000D_
_x000D_
})();

Edit: I have created an NPM package called flat-promise and the code is also available on GitHub.

import datetime as dt
from dateutil.relativedelta import relativedelta

start = "09:35:23"
end = "10:23:00"
start_dt = dt.datetime.strptime(start, "%H:%M:%S")
end_dt = dt.datetime.strptime(end, "%H:%M:%S")
timedelta_obj = relativedelta(start_dt, end_dt)
print(
    timedelta_obj.years,
    timedelta_obj.months,
    timedelta_obj.days,
    timedelta_obj.hours,
    timedelta_obj.minutes,
    timedelta_obj.seconds,
)

result: 0 0 0 0 -47 -37

from s in context.shift
where !context.employeeshift.Any(es=>(es.shiftid==s.shiftid)&&(es.empid==57))
select s;

Hope this helps

As Suhel Meman said in the comments:

SELECT column1, column2, column3 FROM table 1
UNION
SELECT column1, column2, column3 FROM table 2
...

would work.

But all your SELECTS would have to consist of the same amount of columns. And because you are displaying it in one resulting table they should contain the same information.

What you might want to do, is a JOIN on Product ID or something like that. This way you would get more columns, which makes more sense most of the time.

Both answers given worked for the problem I stated -- Thanks!

In my real application though, I was trying to constrain a panel inside of a ScrollViewer and Kent's method didn't handle that very well for some reason I didn't bother to track down. Basically the controls could expand beyond the MaxWidth setting and defeated my intent.

Nir's technique worked well and didn't have the problem with the ScrollViewer, though there is one minor thing to watch out for. You want to be sure the right and left margins on the TextBox are set to 0 or they'll get in the way. I also changed the binding to use ViewportWidth instead of ActualWidth to avoid issues when the vertical scrollbar appeared.

Are you sure you can't alter the HTML in the popup window?

If you can, add a <script> tag at the end of the popup's HTML, and call window.print() inside it. Then it won't be called until the HTML has loaded.

Updated for Python 3:

import csv

with open('file.csv', newline='') as f:
    reader = csv.reader(f)
    your_list = list(reader)

print(your_list)

Output:

[['This is the first line', 'Line1'], ['This is the second line', 'Line2'], ['This is the third line', 'Line3']]

As I was researching this I thought it would be nice to modify the BETWEEN solution to show an example for a particular non-static/string date, but rather a variable date, or today's such as CURRENT_DATE(). This WILL use the index on the log_timestamp column.

SELECT *
FROM some_table
WHERE
    log_timestamp
    BETWEEN 
        timestamp(CURRENT_DATE()) 
    AND # Adds 23.9999999 HRS of seconds to the current date
        timestamp(DATE_ADD(CURRENT_DATE(), INTERVAL '86399.999999' SECOND_MICROSECOND));

I did the seconds/microseconds to avoid the 12AM case on the next day. However, you could also do `INTERVAL '1 DAY' via comparison operators for a more reader-friendly non-BETWEEN approach:

SELECT *
FROM some_table
WHERE
    log_timestamp >= timestamp(CURRENT_DATE()) AND
    log_timestamp < timestamp(DATE_ADD(CURRENT_DATE(), INTERVAL 1 DAY));

Both of these approaches will use the index and should perform MUCH faster. Both seem to be equally as fast.

I actually ended up with something like this to allow for the navbar collapse.

@media (min-width: 768px) { //set this to wherever the navbar collapse executes
  .navbar-nav > li > a{
    line-height: 7em; //set this height to the height of the logo.
  }
}

Unfortunately while I thought these answers may have worked for me, I struggled with a solution, as I'm using tables inside responsive tables - where the overflow-x is played with.

So, with that in mind, have a look at this link for a cleaner way, which doesn't have the weird width overflow issues. It worked for me in the end and was very easy to implement.

If you are using this path to access parts of the projects which are not code (for example an upload directory, or a SQLite database) then it might be better to turn the path into a parameter, like this:

parameters:
    database_path: '%kernel.root_dir%/../var/sqlite3.db'

This parameter can be injected everywhere you need it, so you don't have to mess around with paths in your code any more. Also, the parameter can be overridden at deployment time. Finally, every maintaining programmer will have a better idea what you are using it for.

Update: Fixed kernel.root_dir constant usage.

How to include images in your app

1. Create an assets/images folder

• This should be located in the root of your project, in the same folder as your pubspec.yaml file.
• In Android Studio you can right click in the Project view
• You don't have to call it assets or images. You don't even need to make images a subfolder. Whatever name you use, though, is what you will regester in the pubspec.yaml file.

2. Add your image to the new folder

• You can just copy your image into assets/images. The relative path of lake.jpg, for example, would be assets/images/lake.jpg.

3. Register the assets folder in pubspec.yaml

• Open the pubspec.yaml file that is in the root of your project.

• Add an assets subsection to the flutter section like this:

    flutter:
      assets:
        - assets/images/lake.jpg
  

• If you have multiple images that you want to include then you can leave off the file name and just use the directory name (include the final /):

    flutter:
      assets:
        - assets/images/
  

4. Use the image in code

• Get the asset in an Image widget with Image.asset('assets/images/lake.jpg').

• The entire main.dart file is here:

    import 'package:flutter/material.dart';
  
    void main() => runApp(MyApp());
  
    class MyApp extends StatelessWidget {
      @override
      Widget build(BuildContext context) {
        return MaterialApp(
          home: Scaffold(
            appBar: AppBar(
              title: Text("Image from assets"),
            ),
            body: Image.asset('assets/images/lake.jpg'), //   <--- image
          ),
        );
      }
    }
  

5. Restart your app

When making changes to pubspec.yaml I find that I often need to completely stop my app and restart it again, especially when adding assets. Otherwise I get a crash.

Running the app now you should have something like this:

Further reading

• See the documentation for how to do things like provide alternate images for different densities.

The first video here goes into a lot of detail about how to include images in your app. The second video covers more about how to adjust how they look.

Yes, you can set this by the opposite way:

Here are two quickie approaches I know of:

In base

AQ1 <- airquality
AQ1[is.na(AQ1 <- airquality)] <- 0

Look at AQ1 and see

An easy answer is, your YouTube Channel ID is UC + {YOUR_ACCOUNT_ID}. To be sure of your YouTube Channel ID or your YouTube account ID, access the advanced settings at your settings page

And if you want to know the YouTube Channel ID for any channel, you could use the solution @mjlescano gave.

If this could be of any help, some user marked it was solved in another topic right here.

My app gets installed on client web servers. Rather than fiddling with Network Service permissions and the registry, I opted to check SourceExists and run CreateEventSource in my installer.

I also added a try/catch around log.source = "xx" in the app to set it to a known source if my event source wasn't created (This would only come up if I hot swapped a .dll instead of re-installing).

pandas.DataFrame.append

DataFrame.append(self, other, ignore_index=False, verify_integrity=False, sort=False) ? 'DataFrame'

df = pd.DataFrame([[1, 2], [3, 4]], columns=list('AB'))
df2 = pd.DataFrame([[5, 6], [7, 8]], columns=list('AB'))
df.append(df2)

With ignore_index set to True:

df.append(df2, ignore_index=True)

You can just set the onClick of an ImageView and also set it to be clickable, Or set the drawableBottom property of a regular button.

    ImageView iv = (ImageView)findViewById(R.id.ImageView01);
   iv.setOnClickListener(new OnClickListener() {
   public void onClick(View v) {
    // TODO Auto-generated method stub

   }
   });

I have a char array:

char* name = "hello";

No, you have a character pointer to a string literal. In many usages you could add the const modifier, depending on whether you are more interested in what name points to, or the string value, "hello". You shouldn't attempt to modify the literal ("hello"), because bad things can happen.

The major thing to convey is that C does not have a proper (or first-class) string type. "Strings" are typically arrays of chars (characters) with a terminating null ('\0' or decimal 0) character to signify end of a string, or pointers to arrays of characters.

I would suggest reading Character Arrays, section 1.9 in The C Programming Language (page 28 second edition). I strongly recommend reading this small book ( <300 pages), in order to learn C.

Further to your question, sections 6 - Arrays and Pointers and section 8 - Characters and Strings of the C FAQ might help. Question 6.5, and 8.4 might be good places to start.

I hope that helps you to understand why your excerpt doesn't work. Others have outlined what changes are needed to make it work. Basically you need an char array (an array of characters) big enough to store the entire string with a terminating (ending) '\0' character. Then you can use the standard C library function strcpy (or better yet strncpy) to copy the "Hello" into it, and then you want to concatenate using the standard C library strcat (or better yet strncat) function. You will want to include the string.h header file to declare the functions declarations.

#include <stdio.h>
#include <string.h>
#include <stdlib.h>

int main( int argc, char *argv[] )
{
    char filename[128];
    char* name = "hello";
    char* extension = ".txt";

    if (sizeof(filename) < strlen(name) + 1 ) { /* +1 is for null character */
        fprintf(stderr, "Name '%s' is too long\n", name);
        return EXIT_FAILURE;
    }
    strncpy(filename, name, sizeof(filename));

    if (sizeof(filename) < (strlen(filename) + strlen(extension) + 1) ) {
        fprintf(stderr, "Final size of filename is too long!\n");
        return EXIT_FAILURE;
    }
    strncat(filename, extension, (sizeof(filename) - strlen(filename)) );
    printf("Filename is %s\n", filename);

    return EXIT_SUCCESS;
}

.... but how do we find the equivalent class in the second List to pass to the method below;

This is your actual problem; you must have at least one immutable property, a id or something like that, to identify corresponding objects in both lists. If you do not have such a property you, cannot solve the problem without errors. You can just try to guess corresponding objects by searching for minimal or logical changes.

If you have such an property, the solution becomes really simple.

Enumerable.Join(
   listA, listB,
   a => a.Id, b => b.Id,
   (a, b) => CompareTwoClass_ReturnDifferences(a, b))

thanks to you both danbruc and Noldorin for your feedback. both Lists will be the same length and in the same order. so the method above is close, but can you modify this method to pass the enum.Current to the method i posted above?

Now I am confused ... what is the problem with that? Why not just the following?

for (Int32 i = 0; i < Math.Min(listA.Count, listB.Count); i++)
{
    yield return CompareTwoClass_ReturnDifferences(listA[i], listB[i]);
}

The Math.Min() call may even be left out if equal length is guaranted.

Noldorin's implementation is of course smarter because of the delegate and the use of enumerators instead of using ICollection.

//You may use this example. Might be help you...

$user = User::select("users.*","items.id as itemId","jobs.id as jobId")
        ->join("items","items.user_id","=","users.id")
        ->join("jobs",function($join){
            $join->on("jobs.user_id","=","users.id")
                ->on("jobs.item_id","=","items.id");
        })
        ->get();
print_r($user);

I had a similar problem recently, and needed to change the permissions of my vendor folder

By running following commands :

1. php artisan cache:clear
2. chmod -R 777 storage vendor
3. composer dump-autoload

I need to give all the permissions required to open and write vendor files to solve this issue

#include has nothing to do with projects - it just tells the preprocessor "put the contents of the header file here". If you give it a path that points to the correct location (can be a relative path, like ../your_file.h) it will be included correctly.

You will, however, have to learn about libraries (static/dynamic libraries) in order to make such projects link properly - but that's another question.

In addition to the currently accepted answer: You can set border and background of a checkbox/radiobutton, but how it is rendered in the end depends on the browser. For example, if you set a red background on a checkbox

• IE will show a red border instead
• Opera will show a red background as intended
• Firefox, Safari and Chrome will do nothing

This German language article compares a few browsers and explains at least the IE behavior. It maybe bit older (still including Netscape), but when you test around you'll notice that not much has changed. Another comparison can be found here.

This error usually means you've forgotten a closing quote somewhere in the template you're trying to render. For example: {% url 'my_view %} (wrong) instead of {% url 'my_view' %} (correct). In this case it's the colon that's causing the problem. Normally you'd edit the template to use the correct {% url %} syntax.

But there's no reason why the django admin site would throw this, since it would know it's own syntax. My best guess is therefore that grapelli is causing your problem since it changes the admin templates. Does removing grappelli from installed apps help?

See from How to Replace String in File works in a simple way and is an answer that works with replace

fin = open("data.txt", "rt")
fout = open("out.txt", "wt")

for line in fin:
    fout.write(line.replace('pyton', 'python'))

fin.close()
fout.close()

I was also in the same problem, check your build path in eclipse by Right Click on Project > build path > configure build path

Now check for Excluded Files, it should not have your file specified there by any means or by regex.

Cheers!

Another solution for the original question, esp. useful if you want to remove only SOME of the older files in a folder, would be smth like this:

find . -name "*.sess" -mtime +100 

and so on.. Quotes block shell wildcards, thus allowing you to "find" millions of files :)

Founder a simple solution here:

https://stackoverflow.com/a/47132808/9656339

pd.concat([df1, df2]).loc[df1.index.symmetric_difference(df2.index)]

For me, I needed to keep the TextboxFor() because using EditorFor() changes the input type to date. Which, in Chrome, adds a built in date picker, which screwed up the jQuery datepicker that I was already using. So, to continue using TextboxFor() AND only output the date, you can do this:

<tr>
    <td class="Label">@Html.LabelFor(model => model.DeliveryDate)</td>
    @{
        string deliveryDate = Model.DeliveryDate.ToShortDateString();
    }
    <td>@Html.TextBoxFor(model => model.DeliveryDate, new { @Value = deliveryDate }) *</td>
    <td style="color: red;">@Html.ValidationMessageFor(model => model.DeliveryDate)</td>
</tr>

On what basis should the merging take place? Your question is rather vague. Also, I assume a, b, ..., f are supposed to be strings, that is, 'a', 'b', ..., 'f'.

>>> x = ['a', 'b', 'c', 'd', 'e', 'f', 'g']
>>> x[3:6] = [''.join(x[3:6])]
>>> x
['a', 'b', 'c', 'def', 'g']

Check out the documentation on sequence types, specifically on mutable sequence types. And perhaps also on string methods.

Are you sure the odbc connector is well created ? if not check the step "Create an ODBC Connection" again

EDIT: Connection without DSN from php.net

// Microsoft Access

$connection = odbc_connect("Driver={Microsoft Access Driver (*.mdb)};Dbq=$mdbFilename", $user, $password);

in your case it might be if your filename is northwind and your file extension mdb:

$connection = odbc_connect("Driver={Microsoft Access Driver (*.mdb)};Dbq=northwind", "", "");

A char in C is already a number (the character's ASCII code), no conversion required.

If you want to convert a digit to the corresponding character, you can simply add '0':

c = i +'0';

The '0' is a character in the ASCll table.

There are also these 'ways':

>>> dict.fromkeys(range(1, 4))
{1: None, 2: None, 3: None}
>>> dict(zip(range(1, 4), range(1, 4)))
{1: 1, 2: 2, 3: 3}

Now you can use the pluckmethod on a Collection instance:

This will return only the uuid attribute of the Post model

App\Models\User::find(2)->posts->pluck('uuid')
=> Illuminate\Support\Collection {#983
     all: [
       "1",
       "2",
       "3",
     ],
   }

Check this out : readdir()

This bit of code should list all entries in a certain directory:

if ($handle = opendir('.')) {

    while (false !== ($entry = readdir($handle))) {

        if ($entry != "." && $entry != "..") {

            echo "$entry\n";
        }
    }

    closedir($handle);
}

Edit: miah's solution is much more elegant than mine, you should use his solution instead.

I have a very simple solution for this problem. You don't need to use the console.

TLDR: Create repo, move files to existing projects folder, SourceTree will ask you where his files are, locate the files. Done, your repo is in another folder.

Long answer:

1. Create your new repository on Bitbucket
2. Click "Clone in SourceTree"
3. Let the program put your new repo where it wants, in my case SourceTree created a new folder in My Documents.
4. Locate in windows explorer your new repository folder.
5. Cut the .hg and README (or anything else you find in that folder)
6. Paste it in the location where is your existing project
7. Return to SourceTree and it will say "Error encountered...", just click OK
8. On the left side you will have your repository but with red message: Repository Moved or Deleted. Click on that.
9. Now you will see Repository Missing popup. Click on Change Folder and locate your existing project folder where you have moved the files mentoned earlier.
10. Thats it!

Tips: Clone in SourceTree option is not available right after you create new repository so you first have to click on Create Readme File for that option to become available.

Yeah, you can call other method before of the call base or this!

public class MyException : Exception
{
    public MyException(int number) : base(ConvertToString(number)) 
    {
    }

    private static string ConvertToString(int number) 
    { 
      return number.toString()
    }

}

My solution that finally worked was to clean all projects, close eclipse, clean all projects, close eclipse, and so on at least 5-6 times. Eventually it all settled down and everything was as expected. Weirdest thing ever!!

And no there were no errors in the Problem or console view.

Also this happened after a computer crash. The last time it happened my whole workspace was completely lost. It was still there on the computer, but when I tried to access it, it would be all blank.

For whatever reason computer crashes are really really really badly handled by eclipse.

I had the same problem on VS 2013 and was able to fix it by changing the Platform Toolset.

You can find it in project settings, general.

E.g. switching Platform Toolset to VS 2010 will cause VS to use the Windows\v7.0A SDK.

You can check which SDK path is used by adding this to your prebuild event:

echo using SDK $(WindowsSdkDir)

Math.Round(0.5) returns zero due to floating point rounding errors, so you'll need to add a rounding error amount to the original value to ensure it doesn't round down, eg.

Console.WriteLine(Math.Round(0.5, 0).ToString()); // outputs 0 (!!)
Console.WriteLine(Math.Round(1.5, 0).ToString()); // outputs 2
Console.WriteLine(Math.Round(0.5 + 0.00000001, 0).ToString()); // outputs 1
Console.WriteLine(Math.Round(1.5 + 0.00000001, 0).ToString()); // outputs 2
Console.ReadKey();

Sorry I didn't see your Java tag, was reading question only. I'll leave my other answers here anyway since I've typed them out.

Java

String myString = "9Hello World!";
if ( Character.isDigit(myString.charAt(0)) )
{
    System.out.println("String begins with a digit");
}

C++:

string myString = "2Hello World!";

if (isdigit( myString[0]) )
{
    printf("String begins with a digit");
}

Regular expression:

\b[0-9]

Some proof my regex works: Unless my test data is wrong?

Like @Alexis Dufrenoy proposed, the query could be:

SELECT * FROM `table` WHERE find_in_set('sports', interests)>0 OR find_in_set('pub', interests)>0

As of git v2.23.0 there's a new git restore method which is supposed to assume part of what git checkout was responsible for (even the accepted answer mentions that git checkout is quite confusing). See highlights of changes on github blog.

The default behaviour of this command is to restore the state of a working tree with the content coming from the source parameter (which in your case will be a commit hash).

So based on Greg Hewgill's answer (assuming the commit hash is c5f567) the command would look like this:

git restore --source=c5f567 file1/to/restore file2/to/restore

Or if you want to restore to the content of one commit before c5f567:

git restore --source=c5f567~1 file1/to/restore file2/to/restore

Guys it has very simple solution

https://developers.google.com/instance-id/guides/android-implementation#generate_a_token

Note: If your app used tokens that were deleted by deleteInstanceID, your app will need to generate replacement tokens.

In stead of deleting instance Id, delete only token:

String authorizedEntity = PROJECT_ID;
String scope = "GCM";
InstanceID.getInstance(context).deleteToken(authorizedEntity,scope);

Function can be further improved to render images as well:

function renderHTML(text) { 
    var rawText = strip(text)
    var urlRegex =/(\b(https?|ftp|file):\/\/[-A-Z0-9+&@#\/%?=~_|!:,.;]*[-A-Z0-9+&@#\/%=~_|])/ig;   

    return rawText.replace(urlRegex, function(url) {   

    if ( ( url.indexOf(".jpg") > 0 ) || ( url.indexOf(".png") > 0 ) || ( url.indexOf(".gif") > 0 ) ) {
            return '<img src="' + url + '">' + '<br/>'
        } else {
            return '<a href="' + url + '">' + url + '</a>' + '<br/>'
        }
    }) 
} 

or for a thumbnail image that links to fiull size image:

return '<a href="' + url + '"><img style="width: 100px; border: 0px; -moz-border-radius: 5px; border-radius: 5px;" src="' + url + '">' + '</a>' + '<br/>'

And here is the strip() function that pre-processes the text string for uniformity by removing any existing html.

function strip(html) 
    {  
        var tmp = document.createElement("DIV"); 
        tmp.innerHTML = html; 
        var urlRegex =/(\b(https?|ftp|file):\/\/[-A-Z0-9+&@#\/%?=~_|!:,.;]*[-A-Z0-9+&@#\/%=~_|])/ig;   
        return tmp.innerText.replace(urlRegex, function(url) {     
        return '\n' + url 
    })
} 

Here's an example where isinstance achieves something that type cannot:

class Vehicle:
    pass

class Truck(Vehicle):
    pass

in this case, a truck object is a Vehicle, but you'll get this:

isinstance(Vehicle(), Vehicle)  # returns True
type(Vehicle()) == Vehicle      # returns True
isinstance(Truck(), Vehicle)    # returns True
type(Truck()) == Vehicle        # returns False, and this probably won't be what you want.

In other words, isinstance is true for subclasses, too.

Old thread I know but I am sort of new to Java and discover one of it's strange things. I have used String.replaceAll() but get unpredictable results.

Something like this mess up the string:

sUrl = sUrl.replaceAll( "./", "//").replaceAll( "//", "/");

So I designed this function to get around the weird problem:

//String.replaceAll does not work OK, that's why this function is here
public String strReplace( String s1, String s2, String s ) 
{
    if((( s == null ) || (s.length() == 0 )) || (( s1 == null ) || (s1.length() == 0 )))
     { return s; }

   while( (s != null) && (s.indexOf( s1 ) >= 0) )
    { s = s.replace( s1, s2 ); }
  return s;
}

Which make you able to do:

sUrl=this.strReplace("./", "//", sUrl );
sUrl=this.strReplace( "//", "/", sUrl );

Here's a trick I found to compare two branches and show how many commits each branch is ahead of the other (a more general answer on your question 1):

For local branches: git rev-list --left-right --count master...test-branch

For remote branches: git rev-list --left-right --count origin/master...origin/test-branch

This gives output like the following:

1 7

This output means: "Compared to master, test-branch is 7 commits ahead and 1 commit behind."

You can also compare local branches with remote branches, e.g. origin/master...master to find out how many commits the local master branch is ahead/behind its remote counterpart.

All platforms (Windows, Mac & Linux)

Just go to nodejs.org and download the latest installer. It couldn't be any simpler honestly, and without involvement of any third-party stuff. It only takes a minute and does not require you to restart anything or clean out caches, etc.

I've done it via npm a few times before and have run into a few issues. Like for example with the n-package not using the latest stable release.

You need to call finish() from the UI thread, not a background thread. The way to do this is to declare a Handler and ask the Handler to run a Runnable on the UI thread. For example:

public class LoadingScreen extends Activity{
    private LoadingScreen loadingScreen;
    Intent i = new Intent(this, HomeScreen.class);
    Handler handler;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        handler = new Handler();
        setContentView(R.layout.loading);

        CountDownTimer timer = new CountDownTimer(10000, 1000) //10seceonds Timer
        {
             @Override
             public void onTick(long l) 
             {

             }

             @Override
             public void onFinish() 
             {
                 handler.post(new Runnable() {
                     public void run() {
                         loadingScreen.finishActivity(0);
                         startActivity(i);
                     }
                 });
             };
        }.start();
    }
}

You get this error message if a Python file was closed from "the outside", i.e. not from the file object's close() method:

>>> f = open(".bashrc")
>>> os.close(f.fileno())
>>> del f
close failed in file object destructor:
IOError: [Errno 9] Bad file descriptor

The line del f deletes the last reference to the file object, causing its destructor file.__del__ to be called. The internal state of the file object indicates the file is still open since f.close() was never called, so the destructor tries to close the file. The OS subsequently throws an error because of the attempt to close a file that's not open.

Since the implementation of os.system() does not create any Python file objects, it does not seem likely that the system() call is the origin of the error. Maybe you could show a bit more code?

Node.js and Google Chrome seem to both be using 1024 bit floating point values so:

Number.MAX_VALUE = 1.7976931348623157e+308

I had the same issue and here is how I manage to pass through:

In your case you have addToCount() which is called. now to pass down a param when user clicks, you can say @click="addToCount(item.contactID)"

in your function implementation you can receive the params like:

addToCount(paramContactID){
 // the paramContactID contains the value you passed into the function when you called it
 // you can do what you want to do with the paramContactID in here!

}

If you are using MySQL, you can use order by FIELD(id, ...) approach:

Company.findAll({
    where: {id : {$in : companyIds}},
    order: sequelize.literal("FIELD(company.id,"+companyIds.join(',')+")")
})

Keep in mind, it might be slow. But should be faster, than manual sorting with JS.

There is a subtle issue here that is a bit of a gotcha.

The toString() method has a base implementation in Object. CharSequence is an interface; and although the toString() method appears as part of that interface, there is nothing at compile-time that will force you to override it and honor the additional constraints that the CharSequence toString() method's javadoc puts on the toString() method; ie that it should return a string containing the characters in the order returned by charAt().

Your IDE won't even help you out by reminding that you that you probably should override toString(). For example, in intellij, this is what you'll see if you create a new CharSequence implementation: http://puu.sh/2w1RJ. Note the absence of toString().

If you rely on toString() on an arbitrary CharSequence, it should work provided the CharSequence implementer did their job properly. But if you want to avoid any uncertainty altogether, you should use a StringBuilder and append(), like so:

final StringBuilder sb = new StringBuilder(charSequence.length());
sb.append(charSequence);
return sb.toString();

How about this:

my_hash = HashWithIndifferentAccess.new(YAML.load_file('yml'))

# my_hash['key'] => "val"
# my_hash[:key]  => "val"

[NSTimer scheduledTimerWithTimeInterval:.06 target:self selector:@selector(goToSecondButton:) userInfo:nil repeats:NO];

Is the best one to use. Using sleep(15); will cause the user unable to perform any other actions. With the following function, you would replace goToSecondButton with the appropriate selector or command, which can also be from the frameworks.

Sets

Sets can be combined using mathematical operations.

• The union operator | combines two sets to form a new one containing items in either.
• The intersection operator & gets items only in both.
• The difference operator - gets items in the first set but not in the second.
• The symmetric difference operator ^ gets items in either set, but not both.

Try It Yourself:

first = {1, 2, 3, 4, 5, 6}
second = {4, 5, 6, 7, 8, 9}

print(first | second)

print(first & second)

print(first - second)

print(second - first)

print(first ^ second)

Result:

{1, 2, 3, 4, 5, 6, 7, 8, 9}

{4, 5, 6}

{1, 2, 3}

{8, 9, 7}

{1, 2, 3, 7, 8, 9}

Taken from the MySQL 8.0 Reference Manual:

• utf8mb4: A UTF-8 encoding of the Unicode character set using one to four bytes per character.

• utf8mb3: A UTF-8 encoding of the Unicode character set using one to three bytes per character.

In MySQL utf8 is currently an alias for utf8mb3 which is deprecated and will be removed in a future MySQL release. At that point utf8 will become a reference to utf8mb4.

So regardless of this alias, you can consciously set yourself an utf8mb4 encoding.

To complete the answer, I'd like to add the @WilliamEntriken's comment below (also taken from the manual):

To avoid ambiguity about the meaning of utf8, consider specifying utf8mb4 explicitly for character set references instead of utf8.

Here is the implementation of the Hash Map using python For the simplicity hash map is of a fixed size 16. This can be changed easily. Rehashing is out of scope of this code.

class Node:
    def __init__(self, key, value):
        self.key = key
        self.value = value
        self.next = None

class HashMap:
    def __init__(self):
        self.store = [None for _ in range(16)]
    def get(self, key):
        index = hash(key) & 15
        if self.store[index] is None:
            return None
        n = self.store[index]
        while True:
            if n.key == key:
                return n.value
            else:
                if n.next:
                    n = n.next
                else:

If you are using numpy, you can use dtype 'float128' and get a max float of 10e+4931

>>> np.finfo(np.float128)
finfo(resolution=1e-18, min=-1.18973149536e+4932, max=1.18973149536e+4932, dtype=float128)

use utf8; does not enable Unicode output - it enables you to type Unicode in your program. Add this to the program, before your print() statement:

binmode(STDOUT, ":utf8");

See if that helps. That should make STDOUT output in UTF-8 instead of ordinary ASCII.

The curl installed by default in Debian supports HTTPS since a great while back. (a long time ago there were two separate packages, one with and one without SSL but that's not the case anymore)

OPTIONS /path

You can send an OPTIONS request with curl like this:

curl -i -X OPTIONS http://example.org/path

You may also use -v instead of -i to see more output.

OPTIONS *

To send a plain * (instead of the path, see RFC 7231) with the OPTIONS method, you need curl 7.55.0 or later as then you can run a command line like:

curl -i --request-target "*" -X OPTIONS http://example.org

But from what I understand xs:choice still only allows single element selection. Hence setting the MaxOccurs to unbounded like this should only mean that "any one" of the child elements can appear multiple times. Is this accurate?

No. The choice happens individually for every "repetition" of xs:choice that occurs due to maxOccurs="unbounded". Therefore, the code that you have posted is correct, and will actually do what you want as written.

You can use inbuilt library pickle

This library allows you to save any object in python to a file

This library will maintain the format as well

import pickle
with open('/content/list_1.txt', 'wb') as fp:
    pickle.dump(list_1, fp)

you can also read the list back as an object using same library

with open ('/content/list_1.txt', 'rb') as fp:
    list_1 = pickle.load(fp)

Thank you so much to @Code in another answer. I can read any JSON file thanks to your code. Now, I'm trying to organize all the elements by levels, for could use them!

I was working with Android reading a JSON from an URL and the only I had to change was the lines

Set<Object> set = jsonObject.keySet(); Iterator<Object> iterator = set.iterator();

for

Iterator<?> iterator = jsonObject.keys();

I share my implementation, to help someone:

public void parseJson(JSONObject jsonObject) throws ParseException, JSONException {

    Iterator<?> iterator = jsonObject.keys();
    while (iterator.hasNext()) {
        String obj = iterator.next().toString();

        if (jsonObject.get(obj) instanceof JSONArray) {
            //Toast.makeText(MainActivity.this, "Objeto: JSONArray", Toast.LENGTH_SHORT).show();
            //System.out.println(obj.toString());
            TextView txtView = new TextView(this);
            txtView.setText(obj.toString());
            layoutIzq.addView(txtView);
            getArray(jsonObject.get(obj));
        } else {
            if (jsonObject.get(obj) instanceof JSONObject) {
                //Toast.makeText(MainActivity.this, "Objeto: JSONObject", Toast.LENGTH_SHORT).show();
                parseJson((JSONObject) jsonObject.get(obj));
            } else {
                //Toast.makeText(MainActivity.this, "Objeto: Value", Toast.LENGTH_SHORT).show();
                //System.out.println(obj.toString() + "\t"+ jsonObject.get(obj));
                TextView txtView = new TextView(this);
                txtView.setText(obj.toString() + "\t"+ jsonObject.get(obj));
                layoutIzq.addView(txtView);
            }
        }
    }
}

Note: if you're in a hurry, and/or looking for short answer scroll to the bottom of the answer, and read the last two lines.if Not in a hurry read the whole thing.


let me start by stating the facts:

Syntax:
string.slice(start,end)
string.substr(start,length)
string.substring(start,end)
Note #1: slice()==substring()

What it does?
The slice() method extracts parts of a string and returns the extracted parts in a new string.
The substr() method extracts parts of a string, beginning at the character at the specified position, and returns the specified number of characters.
The substring() method extracts parts of a string and returns the extracted parts in a new string.
Note #2:slice()==substring()

Changes the Original String?
slice() Doesn't
substr() Doesn't
substring() Doesn't
Note #3:slice()==substring()

Using Negative Numbers as an Argument:
slice() selects characters starting from the end of the string
substr()selects characters starting from the end of the string
substring() Doesn't Perform
Note #3:slice()==substr()

if the First Argument is Greater than the Second:
slice() Doesn't Perform
substr() since the Second Argument is NOT a position, but length value, it will perform as usual, with no problems
substring() will swap the two arguments, and perform as usual

the First Argument:
slice() Required, indicates: Starting Index
substr() Required, indicates: Starting Index
substring() Required, indicates: Starting Index
Note #4:slice()==substr()==substring()

the Second Argument:
slice() Optional, The position (up to, but not including) where to end the extraction
substr() Optional, The number of characters to extract
substring() Optional, The position (up to, but not including) where to end the extraction
Note #5:slice()==substring()

What if the Second Argument is Omitted?
slice() selects all characters from the start-position to the end of the string
substr() selects all characters from the start-position to the end of the string
substring() selects all characters from the start-position to the end of the string
Note #6:slice()==substr()==substring()

so, you can say that there's a difference between slice() and substr(), while substring() is basically a copy of slice().

in Summary:
if you know the index(the position) on which you'll stop (but NOT include), Use slice()
if you know the length of characters to be extracted use substr().

To complement Alex's response, I would add that starting from Python 2.2.0a2, from __future__ import division is a convenient alternative to using lots of float(…)/…. All divisions perform float divisions, except those with //. This works with all versions from 2.2.0a2 on.

If performance is not critical (e.g., the amount of keys is relatively small) and you don't want to pollute your (or maybe not your) objects with additional fields like _hash, _id, etc., then you can make use of the fact that Array.prototype.indexOf employs strict equality. Here is a simple implementation:

var Dict = (function(){
    // Internet Explorer 8 and earlier does not have any Array.prototype.indexOf
    function indexOfPolyfill(val) {
      for (var i = 0, l = this.length; i < l; ++i) {
        if (this[i] === val) {
          return i;
        }
      }
      return -1;
    }

    function Dict(){
      this.keys = [];
      this.values = [];
      if (!this.keys.indexOf) {
        this.keys.indexOf = indexOfPolyfill;
      }
    };

    Dict.prototype.has = function(key){
      return this.keys.indexOf(key) != -1;
    };

    Dict.prototype.get = function(key, defaultValue){
      var index = this.keys.indexOf(key);
      return index == -1 ? defaultValue : this.values[index];
    };

    Dict.prototype.set = function(key, value){
      var index = this.keys.indexOf(key);
      if (index == -1) {
        this.keys.push(key);
        this.values.push(value);
      } else {
        var prevValue = this.values[index];
        this.values[index] = value;
        return prevValue;
      }
    };

    Dict.prototype.delete = function(key){
      var index = this.keys.indexOf(key);
      if (index != -1) {
        this.keys.splice(index, 1);
        return this.values.splice(index, 1)[0];
      }
    };

    Dict.prototype.clear = function(){
      this.keys.splice(0, this.keys.length);
      this.values.splice(0, this.values.length);
    };

    return Dict;
})();

Example of usage:

var a = {}, b = {},
    c = { toString: function(){ return '1'; } },
    d = 1, s = '1', u = undefined, n = null,
    dict = new Dict();

// Keys and values can be anything
dict.set(a, 'a');
dict.set(b, 'b');
dict.set(c, 'c');
dict.set(d, 'd');
dict.set(s, 's');
dict.set(u, 'u');
dict.set(n, 'n');

dict.get(a); // 'a'
dict.get(b); // 'b'
dict.get(s); // 's'
dict.get(u); // 'u'
dict.get(n); // 'n'
// etc.

Comparing to ECMAScript 6 WeakMap, it has two issues: O(n) search time and non-weakness (i.e., it will cause memory leak if you don't use delete or clear to release keys).

Another way would be using:

myCursor.getCount();

on a Cursor like:

Cursor myCursor = db.query(table_Name, new String[] { row_Username }, 
row_Username + " =? AND " + row_Password + " =?",
new String[] { entered_Password, entered_Password }, 
null, null, null);

If you can think of getting away from the raw query.

If it's just renaming the file, you can use File.renameTo().

In the case where you want to append the contents of the second file to the first, take a look at FileOutputStream with the append constructor option or The same thing for FileWriter. You'll need to read the contents of the file to append and write them out using the output stream/writer.

All the other answers here give good advice for various situations, but there is an easier way.

The rbenv docs point us to the rbenv-doctor diagnostic tool that will quickly verify all these potential pitfalls on your system:

Documentation: C.2.3.1 <jee:jndi-lookup/> (simple)

Example:

<jee:jndi-lookup id="dataSource" jndi-name="jdbc/MyDataSource"/>

You just need to find out what JNDI name your appserver has bound the datasource to. This is entirely server-specific, consult the docs on your server to find out how.

Remember to declare the jee namespace at the top of your beans file, as described in C.2.3 The jee schema.

if just everything could be this simple...

#logo a {padding-top:48px; display:block;}



<div id="logo"><a href="../../index.html"></a></div>

just think a little outside the box ;-)

Actually this is the path and you should mention a valid path for this to work. If your data directory is in current directory then instead of my-data you should mention ./my-data, otherwise it will give you that error in mysql and mariadb also.

volumes:
 ./my-data:/var/lib/mysql

Have you tried adding lines below to your web.xml?

<context-param>
   <param-name>com.sun.faces.enableRestoreView11Compatibility</param-name>
   <param-value>true</param-value>
</context-param>

I found this to be very effective when I encountered this issue.

okay, you can do this in one line of code. you'll need json2.js for this (you probably already have.). the two json objects here are unparsed strings.

json1 = '[{"foo":"bar"},{"bar":"foo"},{"name":"craig"}]';

json2 = '[{"foo":"baz"},{"bar":"fob"},{"name":"george"}]';

concattedjson = JSON.stringify(JSON.parse(json1).concat(JSON.parse(json2)));

Try the below script to find last argument

 # cat arguments.sh
 #!/bin/bash
 if [ $# -eq 0 ]
 then
 echo "No Arguments supplied"
 else
 echo $* > .ags
 sed -e 's/ /\n/g' .ags | tac | head -n1 > .ga
 echo "Last Argument is: `cat .ga`"
 fi

Output:

 # ./arguments.sh
 No Arguments supplied

 # ./arguments.sh testing for the last argument value
 Last Argument is: value

Thanks.

In addition to the accepted answer, one other check is to make sure that you have the right reference to your entity package in sessionFactory.setPackagesToScan(...) while setting up your session factory.

In my instance, I decided to solve this via a one-line lambda to create a new decorator function:

def finished_message(function, message="Finished!"):

    def wrapper(*args, **kwargs):
        output = function(*args,**kwargs)
        print(message)
        return output

    return wrapper

@finished_message
def func():
    pass

my_finished_message = lambda f: finished_message(f, "All Done!")

@my_finished_message
def my_func():
    pass

if __name__ == '__main__':
    func()
    my_func()

When executed, this prints:

Finished!
All Done!

Perhaps not as extensible as other solutions, but worked for me.

The answer from @gunn is correct, target="_blank makes the link open in a new tab.

But this can be a security risk for you page; you can read about it here. There is a simple solution for that: adding rel="noopener noreferrer".

<a style={{display: "table-cell"}} href = "someLink" target = "_blank" 
rel = "noopener noreferrer">text</a>

Try this

$str = '<option value="123">abc</option>
        <option value="123">aabbcc</option>';

preg_match_all("#<option.*?>([^<]+)</option>#", $str, $foo);

print_r($foo[1]);

The way a cherry-pick works is by taking the diff a changeset represents (the difference between the working tree at that point and the working tree of its parent), and applying it to your current branch.

So, if a commit has two or more parents, it also represents two or more diffs - which one should be applied?

You're trying to cherry pick fd9f578, which was a merge with two parents. So you need to tell the cherry-pick command which one against which the diff should be calculated, by using the -m option. For example, git cherry-pick -m 1 fd9f578 to use parent 1 as the base.

I can't say for sure for your particular situation, but using git merge instead of git cherry-pick is generally advisable. When you cherry-pick a merge commit, it collapses all the changes made in the parent you didn't specify to -m into that one commit. You lose all their history, and glom together all their diffs. Your call.

Building on this question, I use the following code to indent my messages:

String prefix1 = "short text:";
String prefix2 = "looooooooooooooong text:";
String msg = "indented";
/*
* The second string begins after 40 characters. The dash means that the
* first string is left-justified.
*/
String format = "%-40s%s%n";
System.out.printf(format, prefix1, msg);
System.out.printf(format, prefix2, msg);

This is the output:

short text:                             indented
looooooooooooooong text:                indented

This is documented in section "Flag characters" in man 3 printf.

To start, using the same ID twice is not a good idea. ID's should be unique, if you need to style elements you should use a class to apply CSS instead.

At last, you defined the name of your submit button as Tea and Coffee, but in your PHP you are using submit as index. your index should have been $_POST['Tea'] for example. that would require you to check for it being set as it only sends one , you can do that with isset().

Buy anyway , user4035 just beat me to it , his code will "fix" this for you.

Here is the example directly from PEP 8 on limiting line length:

class Rectangle(Blob):

    def __init__(self, width, height,
                 color='black', emphasis=None, highlight=0):
        if (width == 0 and height == 0 and
                color == 'red' and emphasis == 'strong' or
                highlight > 100):
            raise ValueError("sorry, you lose")
        if width == 0 and height == 0 and (color == 'red' or
                                           emphasis is None):
            raise ValueError("I don't think so -- values are %s, %s" %
                             (width, height))
        Blob.__init__(self, width, height,
                      color, emphasis, highlight)

You can make the button an anchor element, and put it in a paragraph with the attribute:

align='center'

Worked for me.

My problem was a mistake in importing:

I imported my function into the router/index.js like below:

const { index } = require('../controllers');

and used it like this:

router.get('/', index.index);

This was my mistake. I must have used this:

router.get('/', index);

So I changed it to the line above and my problem got solved.

This is a good exercise for yourself to work on :)

You should break your library into three parts

• Loading the CSV file
• Representing the file in memory so that you can modify it and read it
• Saving the CSV file back to disk

So you are looking at writing a CSVDocument class that contains:

• Load(const char* file);
• Save(const char* file);
• GetBody

So that you may use your library like this:

CSVDocument doc;
doc.Load("file.csv");
CSVDocumentBody* body = doc.GetBody();

CSVDocumentRow* header = body->GetRow(0);
for (int i = 0; i < header->GetFieldCount(); i++)
{
    CSVDocumentField* col = header->GetField(i);
    cout << col->GetText() << "\t";
}

for (int i = 1; i < body->GetRowCount(); i++) // i = 1 so we skip the header
{
    CSVDocumentRow* row = body->GetRow(i);
    for (int p = 0; p < row->GetFieldCount(); p++)
    {
        cout << row->GetField(p)->GetText() << "\t";
    }
    cout << "\n";
}

body->GetRecord(10)->SetText("hello world");

CSVDocumentRow* lastRow = body->AddRow();
lastRow->AddField()->SetText("Hey there");
lastRow->AddField()->SetText("Hey there column 2");

doc->Save("file.csv");

Which gives us the following interfaces:

class CSVDocument
{
public:
    void Load(const char* file);
    void Save(const char* file);

    CSVDocumentBody* GetBody();
};

class CSVDocumentBody
{
public:
    int GetRowCount();
    CSVDocumentRow* GetRow(int index);
    CSVDocumentRow* AddRow();
};

class CSVDocumentRow
{
public:
    int GetFieldCount();
    CSVDocumentField* GetField(int index);
    CSVDocumentField* AddField(int index);
};

class CSVDocumentField
{
public:
    const char* GetText();
    void GetText(const char* text);
};

Now you just have to fill in the blanks from here :)

Believe me when I say this - investing your time into learning how to make libraries, especially those dealing with the loading, manipulation and saving of data, will not only remove your dependence on the existence of such libraries but will also make you an all-around better programmer.

:)

EDIT

I don't know how much you already know about string manipulation and parsing; so if you get stuck I would be happy to help.

I tried following code, which works for me.

private boolean executeCommand(){
        System.out.println("executeCommand");
        Runtime runtime = Runtime.getRuntime();
        try
        {
            Process  mIpAddrProcess = runtime.exec("/system/bin/ping -c 1 8.8.8.8");
            int mExitValue = mIpAddrProcess.waitFor();
            System.out.println(" mExitValue "+mExitValue);
            if(mExitValue==0){
                return true;
            }else{
                return false;
            }
        }
        catch (InterruptedException ignore)
        {
            ignore.printStackTrace();
            System.out.println(" Exception:"+ignore);
        } 
        catch (IOException e) 
        {
            e.printStackTrace();
            System.out.println(" Exception:"+e);
        }
        return false;
    }

You can also write it like this:

let elem: any;
elem = $("div.printArea");
elem.printArea();

I was also stuck on this problem then I saw that the ids of the modal are the same. You need different ids of modals if you want multiple modals. I used dynamic id. Here is my code in haml:

.modal.hide.fade{"id"=> discount.id,"aria-hidden" => "true", "aria-labelledby" => "myModalLabel", :role => "dialog", :tabindex => "-1"}

you can do this

<div id="<%= some.id %>" class="modal hide fade in">
  <div class="modal-header">
    <a class="close" data-dismiss="modal">×</a>
    <h3>Header</h3>
  </div>
  <div class="modal-body"></div>
  <div class="modal-footer">
    <input type="submit" class="btn btn-success" value="Save" />
  </div>
</div>

and your links to modal will be

<a data-toggle="modal" data-target="#" href='"#"+<%= some.id %>' >Open modal</a>
<a data-toggle="modal" data-target="#myModal" href='"#"+<%= some.id %>' >Open modal</a>
<a data-toggle="modal" data-target="#myModal" href='"#"+<%= some.id %>' >Open modal</a>

I hope this will work for you.

Add a vertical-align property to the TD, like this:

<td style="width: 259px; vertical-align: top;">
main page
</td>

Another option

echo foo >>/dev/stderr

You can have a look at python docs (docs.python.org in the FAQ), but more specifically for a good explanation the mysterious miss args and mister kwargs (courtesy of archive.org) (the original, dead link is here).

In a nutshell, both are used when optional parameters to a function or method are used. As Dave says, *args is used when you don't know how many arguments may be passed, and **kwargs when you want to handle parameters specified by name and value as in:

myfunction(myarg=1)

Try the following snippet:

var mystring = 'this,is,an,example';
var splits = mystring.split(",");
alert(splits[0]); // output: this

display: none is solution, That's completely hides elements with its space.

Story about display:none and visibility: hidden

visibility:hidden means the tag is not visible, but space is allocated for it on the page.

display:none means completely hides elements with its space. (although you can still interact with it through the DOM)

one can print values using the format method in python. This small example will help take input of two numbers a and b. Print a+b in first line and a-b in second line

print('{:d}\n{:d}'.format(a+b,a-b))

Similarly in the answer we can do

print ("{0}. {1} appears {2} times.".format(22, 'c', 9999))

The python method format() for string is used to specify a string format. So {0},{1},{2} are like array indexes called as positional parameters. Therefore {0} is assigned first value written in format (a+b), {1} is assigned the second value (a-b) and so on. We can also use keyword instead of positional parameter like for example

print("Hi! my name is {name}".format(name="rashi"))

Therefore name here is the keyword and its value is Rashi Hope it helps :)

Another possible solution I came up with was:

re.sub(r'([uU]+(.)?\s)',' you ', text)

You can replace your old dictionary with a defaultdict:

>>> from collections import defaultdict
>>> d = {'foo': 123, 'bar': 456}
>>> d['baz']
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
KeyError: 'baz'
>>> d = defaultdict(lambda: -1, d)
>>> d['baz']
-1

The "trick" here is that a defaultdict can be initialized with another dict. This means that you preserve the existing values in your normal dict:

>>> d['foo']
123

Try this

$("#abc").html('<span class = "xyz"> SAMPLE TEXT</span>');

Handle all the css relevant to that span within xyz

Albeit a bit stale, this library offers a tested and robust conversion API:

https://github.com/gabrielelana/byte-units

Once installed:

\ByteUnits\Binary::bytes(1024)->format();

// Output: "1.00KiB"

And to convert in the other direction:

\ByteUnits\Binary::parse('1KiB')->numberOfBytes();

// Output: "1024"

Beyond basic conversion, it offers methods for addition, subtraction, comparison, etc.

I am no way affiliated with this library.

It should have been in this standard date format YYYY-MM-DD, to use below equation. You may have time along with example: 2020-04-24 16:51:56 or 2020-04-24T16:51:56+05:30. It will work fine but date format should like this YYYY-MM-DD only.

var myDate = "2020-04-24";
var timestamp = +new Date(myDate)

A separate use case: when your text file is version controlled (in this case specifically under git although it applies to others too). If content is added to the end of the file, then the line that was previously the last line will have been edited to include a newline character. This means that blameing the file to find out when that line was last edited will show the text addition, not the commit before that you actually wanted to see.

userpicture.setImageBitmap(mIcon1);

As slight improvement to @MONTYHS answer, iterating through a tup of fieldnames:

import csv
import json

csvfilename = 'filename.csv'
jsonfilename = csvfilename.split('.')[0] + '.json'
csvfile = open(csvfilename, 'r')
jsonfile = open(jsonfilename, 'w')
reader = csv.DictReader(csvfile)

fieldnames = ('FirstName', 'LastName', 'IDNumber', 'Message')

output = []

for each in reader:
  row = {}
  for field in fieldnames:
    row[field] = each[field]
output.append(row)

json.dump(output, jsonfile, indent=2, sort_keys=True)

By default, there is not any proper answer to disable saving a password in your browser. But luckily there is a way around and it works in almost all the browsers.

To achieve this, add a dummy input just before the actual input with autocomplete="off" and some custom styling to hide it and providing tabIndex.

Some browsers' (Chrome) autocomplete will fill in the first password input it finds, and the input before that, so with this trick it will only fill in an invisible input that doesn't matter.

          <div className="password-input">
            <input
              type="password"
              id="prevent_autofill"
              autoComplete="off"
              style={{
                opacity: '0',
                position: 'absolute',
                height: '0',
                width: '0',
                padding: '0',
                margin: '0'
              }}
              tabIndex="-2"
            />
            <input
              type="password"
              autoComplete="off"
              className="password-input-box"
              placeholder="Password"
              onChange={e => this.handleChange(e, 'password')}
            />
          </div>

for (prop in obj) {
    alert(prop + ' = ' + obj[prop]);

You need an uppercase M for the month part.

string strDate = DateTime.Now.ToString("MM/dd/yyyy");

Lowercase m is for outputting (and parsing) a minute (such as h:mm).

e.g. a full date time string might look like this:

string strDate = DateTime.Now.ToString("MM/dd/yyyy h:mm");

Notice the uppercase/lowercase mM difference.

Also if you will always deal with the same datetime format string, you can make it easier by writing them as C# extension methods.

public static class DateTimeMyFormatExtensions
{
  public static string ToMyFormatString(this DateTime dt)
  {
    return dt.ToString("MM/dd/yyyy");
  }
}

public static class StringMyDateTimeFormatExtension
{
  public static DateTime ParseMyFormatDateTime(this string s)
  {
    var culture = System.Globalization.CultureInfo.CurrentCulture;
    return DateTime.ParseExact(s, "MM/dd/yyyy", culture);
  }
}

EXAMPLE: Translating between DateTime/string

DateTime now = DateTime.Now;

string strNow = now.ToMyFormatString();
DateTime nowAgain = strNow.ParseMyFormatDateTime();

Note that there is NO way to store a custom DateTime format information to use as default as in .NET most string formatting depends on the currently set culture, i.e.

System.Globalization.CultureInfo.CurrentCulture.

The only easy way you can do is to roll a custom extension method.

Also, the other easy way would be to use a different "container" or "wrapper" class for your DateTime, i.e. some special class with explicit operator defined that automatically translates to and from DateTime/string. But that is dangerous territory.

def (value1, value2) = '1128-2'.split('-') should work.

Can anyone please try this in Groovy Console?

def (v, z) =  '1128-2'.split('-')

assert v == '1128'
assert z == '2'

I think Nosql is "more suitable" in these scenarios at least (more supplementary is welcome)

1. Easy to scale horizontally by just adding more nodes.

2. Query on large data set

   Imagine tons of tweets posted on twitter every day. In RDMS, there could be tables with millions (or billions?) of rows, and you don't want to do query on those tables directly, not even mentioning, most of time, table joins are also needed for complex queries.

3. Disk I/O bottleneck

   If a website needs to send results to different users based on users' real-time info, we are probably talking about tens or hundreds of thousands of SQL read/write requests per second. Then disk i/o will be a serious bottleneck.

public int getActionBarHeight() {
    int actionBarHeight = 0;
    TypedValue tv = new TypedValue();
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
        if (getTheme().resolveAttribute(android.R.attr.actionBarSize, tv,
                true))
            actionBarHeight = TypedValue.complexToDimensionPixelSize(
                    tv.data, getResources().getDisplayMetrics());
    } else {
        actionBarHeight = TypedValue.complexToDimensionPixelSize(tv.data,
                getResources().getDisplayMetrics());
    }
    return actionBarHeight;
}

If you want to pass variables to the server using GET that would be the way yes. Remember to escape (urlencode) them properly!

It is also possible to use POST, if you dont want your variables to be visible.

A complete sample would be:

var url = "bla.php";
var params = "somevariable=somevalue&anothervariable=anothervalue";
var http = new XMLHttpRequest();

http.open("GET", url+"?"+params, true);
http.onreadystatechange = function()
{
    if(http.readyState == 4 && http.status == 200) {
        alert(http.responseText);
    }
}
http.send(null);

To test this, (using PHP) you could var_dump $_GET to see what you retrieve.

TCPView can do what you asked for.

Ok, no one has answered this yet but I managed to figure it out and get it working after also posting on the spyder discussion boards. For any libraries that you want to add that aren't included in the default search path of spyder, you need to go into Tools and add a path to each library via the PYTHONPATH manager. You'll then need to update the module names list from the same menu and restart spyder before the changes take effect.

Obfuscate the code! There is an example in Obfuscating C# Code.

Add a static method inside your functional interface

package example;

interface Action<T, U> {
       U execute(T t);
       static  Action<Void,Void> invoke(Runnable runnable){
           return (v) -> {
               runnable.run();
                return null;
            };         
       }
    }

public class Lambda {


    public static void main(String[] args) {

        Action<Void, Void> a = Action.invoke(() -> System.out.println("Do nothing!"));
        Void t = null;
        a.execute(t);
    }

}

Output

Do nothing!

Here's a flow chart that illustrates a for loop:

The equivalent C code would be

for(i = 2; i <= 6; i = i + 2) {
    printf("%d\t", i + 1);
}

I found this and several other examples on one of Tenouk's C Laboratory practice worksheets.

Missing ; after var_dump($row)

Within the parent, you can reference the child using @ViewChild. When needed (i.e. when the event would be fired), you can just execute a method in the child from the parent using the @ViewChild reference.

Bruno's answer was the correct one in the end. This is most easily controlled by the https.protocols system property. This is how you are able to control what the factory method returns. Set to "TLSv1" for example.

You could use the UPPER keyword:

SELECT *
FROM Customers
WHERE UPPER(LastName) = UPPER('AnGel')

The doc in Java 8 names it fraction-of-second , while in Java 6 was named millisecond. This brought me to confusion

You can remove the 2nd argument type array [] but the fetchBusinesses() will also be called every update. You can add an IF statement into the fetchBusinesses() implementation if you like.

React.useEffect(() => {
  fetchBusinesses();
});

The other one is to implement the fetchBusinesses() function outside your component. Just don't forget to pass any dependency arguments to your fetchBusinesses(dependency) call, if any.

function fetchBusinesses (fetch) {
  return fetch("theURL", { method: "GET" })
    .then(res => normalizeResponseErrors(res))
    .then(res => res.json())
    .then(rcvdBusinesses => {
      // some stuff
    })
    .catch(err => {
      // some error handling
    });
}

function YourComponent (props) {
  const { fetch } = props;

  React.useEffect(() => {
    fetchBusinesses(fetch);
  }, [fetch]);

  // ...
}

Instead of installing a library inside Jupyter, I would recommend you use the 'Dark Reader' extension in Chrome (you can find 'Dark Reader' extension in other browsers, e.g. Firefox). You can play with it; filter the URL(s) you want to have dark theme, or even how define the Dark theme for yourself. Below are couple of examples:

I hope it helps.

We should rather use Javascript.

    <button href="images/car.jpg" id="myButton">
        Here is the Button to be clicked
    </button>

        $(document).ready(function(){
            document.getElementById("myButton").click();
        });

Although all the answers are really helpful, there's one tiny piece of information that should be explained explicitly:

• Essentially, a project with multiple hierarchical directories work as a package with some attributes.
• To import custom local created Classes, we need to navigate to the directory containing .py file and create an __init__.py (empty) file there.

Why this helps is because this file is required to make Python treat the directory as containing packages. Cheers!

you can use just

Here is a complete test case that simulates the click event, calls all handlers attached (however they have been attached), maintains the "target" attribute ("srcElement" in IE), bubbles like a normal event would, and emulates IE's recursion-prevention. Tested in FF 2, Chrome 2.0, Opera 9.10 and of course IE (6):

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<script>
function fakeClick(event, anchorObj) {
  if (anchorObj.click) {
    anchorObj.click()
  } else if(document.createEvent) {
    if(event.target !== anchorObj) {
      var evt = document.createEvent("MouseEvents"); 
      evt.initMouseEvent("click", true, true, window, 
          0, 0, 0, 0, 0, false, false, false, false, 0, null); 
      var allowDefault = anchorObj.dispatchEvent(evt);
      // you can check allowDefault for false to see if
      // any handler called evt.preventDefault().
      // Firefox will *not* redirect to anchorObj.href
      // for you. However every other browser will.
    }
  }
}
</script>
</head>
<body>

<div onclick="alert('Container clicked')">
  <a id="link" href="#" onclick="alert((event.target || event.srcElement).innerHTML)">Normal link</a>
</div>

<button type="button" onclick="fakeClick(event, document.getElementById('link'))">
  Fake Click on Normal Link
</button>

<br /><br />

<div onclick="alert('Container clicked')">
    <div onclick="fakeClick(event, this.getElementsByTagName('a')[0])"><a id="link2" href="#" onclick="alert('foo')">Embedded Link</a></div>
</div>

<button type="button" onclick="fakeClick(event, document.getElementById('link2'))">Fake Click on Embedded Link</button>

</body>
</html>

Demo here.

It avoids recursion in non-IE browsers by inspecting the event object that is initiating the simulated click, by inspecting the target attribute of the event (which remains unchanged during propagation).

Obviously IE does this internally holding a reference to its global event object. DOM level 2 defines no such global variable, so for that reason the simulator must pass in its local copy of event.

How do I find the Django virtual environment name if I forgot?. It is very Simple, you can find from the following location, if you forgot Django Virtual Environment name on Windows 10 Operating System.

Since pip is an executable and which returns path of executables or filenames in environment. It is correct. Pip module is installed in site-packages but the executable is installed in bin.

In my program I first check for Terminal Server and use the WTSClientHardwareId. Else the MAC address of the local PC should be adequate.

If you really want to use the list of properties you provided leave out things like Name and DriverVersion, Clockspeed, etc. since it's possibly OS dependent. Try outputting the same info on both operating systems and leave out that which differs between.

// in foo.h
class Foo {
    static const unsigned char* Msg;
};

// in foo.cpp
static const unsigned char Foo_Msg_data[] = {0x00,0x01};
const unsigned char* Foo::Msg = Foo_Msg_data;

If you use node.js 0.12 or above / typescript 1.4 or above, just add compiler options like:

tsc a.ts --target es6 --module commonjs

More info: https://github.com/Microsoft/TypeScript/wiki/Compiler-Options

If you use tsconfig.json, then like this:

{
    "compilerOptions": {
        "module": "commonjs",
        "target": "es6"
    }
}

The best and tested solution is to put the following small snippet which will collapse the accordion tab which is already open when you load. In my case the last sixth tab was open so I made it collapsed on page load.

 $(document).ready(){
      $('#collapseSix').collapse("hide");
 }

1. Please check if you have two Android versions installed, if yes uninstall it as two versions can’t run at the same time.
2. Also, you may try to set android-sdk in the flutter config where you can deploy directly to devices from Android Studio

To modify a value every time a block of code runs without having to break execution flow:

The "Logpoints" feature in the debugger is designed to let you log arbitrary values to the console without breaking. It evaluates code inside the flow of execution, which means you can actually use it to change values on the fly without stopping.

Right-click a line number and choose "Logpoint," then enter the assignment expression. It looks something like this:

I find it super useful for setting values to a state not otherwise easy to reproduce, without having to rebuild my project with debug lines in it. REMEMBER to delete the breakpoint when you're done!

In ubuntu to install php_soap on PHP7 use below commands. Reference

sudo apt-get install php7.0-soap
sudo systemctl restart apache2.service

For older version of php use below command and restart apache.

apt-get install php-soap

If I understand well you can only check if a listener has been checked but not which listener is presenter specifically.

So some ad hoc code would fill the gap to handle your coding flow. A practical method would be to create a state using variables. For example, attach a listener's checker as following:

var listenerPresent=false

then if you set a listener just change the value:

listenerPresent=true

then inside your eventListener 's callback you can assign specific functionalities inside and in this same way, distribute the access to functionalities depending of some state as variable for example:

accessFirstFunctionality=false
accessSecondFunctionality=true
accessThirdFunctionality=true

If you set the server output in ON mode before the entire code, it works, otherwise put_line() will not work. Try it!

The code is,

set serveroutput on;
CREATE OR REPLACE PROCEDURE PROC1(invoicenr IN NUMBER, amnt OUT NUMBER)
AS BEGIN
SELECT AMOUNT INTO amnt FROM INVOICE WHERE INVOICE_NR = invoicenr;
END;

And then call the function as it is:

DECLARE
amount NUMBER;
BEGIN
PROC1(1000001, amount);
dbms_output.put_line(amount);
END;

This questions seems a little bit outdated but here is my solution.

I assume that you have already downloaded GlassFish on your hard drive and unzipped the files on a directory.

A - Eclipse MarketPlace / Installing GlassFish Tools

The first thing as it is said on previous answers, you have to downloaded GlassFish Tools from eclipse marketplace;

Help -> EclipseMarket Place

And install GlassFish on the screen below;

B - Adding GlassFish Server

Open Server View, if it is not visible on the bottom of the eclipse, then;

Window -> Show View -> Servers

As the server view is visible, simply click "No servers are available. Click this link to create a new server..." as shown below;

C - Adding GlassFish Server

On the New Server window, select GlassFish as shown below. On my experience, there is only one GlassFish option that I can select, instead of several GlassFish options with versions as you can see down below;

D - Configuring GlassFish & Java Locations

Enter the exact GlassFish location and also Java location as you can see below;

E - Last Step

On the last step of this configuration, just leave everything as it is. For simplicity, I don't define an admin password;

Now everything is all set, hope that this helps!

According to the YAML spec, neither the : nor the - should be a problem. : is only a key separator with a space after it, and - is only an array indicator at the start of a line with a space after it.

But if your YAML implementation has a problem with it, you potentially have lots of options:

- url: 'http://www.example-site.com/'
- url: "http://www.example-site.com/"
- url:
    http://www.example-site.com/
- url: >-
    http://www.example-site.com/
- url: |-
    http://www.example-site.com/

There is explicitly no form of escaping possible in "plain style", however.

I use @gnarf's method, though I fall back on document.writelning a <script> tag for IE<7 as I couldn't get DOM creation to work reliably in IE6 (and TBH didn't care enough to put much effort into it). The core of my code is:

if (horus.script.broken) {
    document.writeln('<script type="text/javascript" src="'+script+'"></script>');   
    horus.script.loaded(script);
} else {
    var s=document.createElement('script');
    s.type='text/javascript';
    s.src=script;
    s.async=true;

    if (horus.brokenDOM){
        s.onreadystatechange=
            function () {
                if (this.readyState=='loaded' || this.readyState=='complete'){
                    horus.script.loaded(script);
                }
        }
    }else{
        s.onload=function () { horus.script.loaded(script) };
    }

    document.head.appendChild(s);
}

where horus.script.loaded() notes that the javascript file is loaded, and calls any pending uncalled routines (saved by autoloader code).

I will expand on the earlier answer about np.fliplr(). Here is some code that demonstrates constructing a 1d array, transforming it into a 2d array, flipping it, then converting back into a 1d array. time.clock() will be used to keep time, which is presented in terms of seconds.

import time
import numpy as np

start = time.clock()
x = np.array(range(3))
#transform to 2d
x = np.atleast_2d(x)
#flip array
x = np.fliplr(x)
#take first (and only) element
x = x[0]
#print x
end = time.clock()
print end-start

With print statement uncommented:

[2 1 0]
0.00203907123594

With print statement commented out:

5.59799927506e-05

So, in terms of efficiency, I think that's decent. For those of you that love to do it in one line, here is that form.

np.fliplr(np.atleast_2d(np.array(range(3))))[0]

We're using Kafka 2.11 and make use of this tool - kafka-consumer-groups.

$ rpm -qf /bin/kafka-consumer-groups
confluent-kafka-2.11-1.1.1-1.noarch

For example:

$ kafka-consumer-groups --describe --group logstash | grep -E "TOPIC|filebeat"

Random Tip

NOTE: We use an alias that overloads kafka-consumer-groups like so in our /etc/profile.d/kafka.sh:

alias kafka-consumer-groups="KAFKA_JVM_PERFORMANCE_OPTS=\"-Djava.security.auth.login.config=$HOME/.kafka_client_jaas.conf\"  kafka-consumer-groups --bootstrap-server ${KAFKA_HOSTS} --command-config /etc/kafka/security-enabler.properties"

If you have a return value you need to send to the UI you can use the generic version like this:

This is being called from an MVVM ViewModel in my case.

var updateManifest = Task<ShippingManifest>.Run(() =>
    {
        Thread.Sleep(5000);  // prove it's really working!

        // GenerateManifest calls service and returns 'ShippingManifest' object 
        return GenerateManifest();  
    })

    .ContinueWith(manifest =>
    {
        // MVVM property
        this.ShippingManifest = manifest.Result;

        // or if you are not using MVVM...
        // txtShippingManifest.Text = manifest.Result.ToString();    

        System.Diagnostics.Debug.WriteLine("UI manifest updated - " + DateTime.Now);

    }, TaskScheduler.FromCurrentSynchronizationContext());

That's the simplest way I can think for finding duplicates in a list:

my_list = [3, 5, 2, 1, 4, 4, 1]

my_list.sort()
for i in range(0,len(my_list)-1):
               if my_list[i] == my_list[i+1]:
                   print str(my_list[i]) + ' is a duplicate'

how about (for char c)

int i = (int)(c - '0');

which does substraction of the char value?

Re the API question (comments), perhaps an extension method?

public static class CharExtensions {
    public static int ParseInt32(this char value) {
        int i = (int)(value - '0');
        if (i < 0 || i > 9) throw new ArgumentOutOfRangeException("value");
        return i;
    }
}

then use int x = c.ParseInt32();

Shockingly, the syntax has changed yet again in the latest version of Angular :-) From the Angular 6 docs:

Beginning with Angular 6.0, the preferred way to create a singleton services is to specify on the service that it should be provided in the application root. This is done by setting providedIn to root on the service's @Injectable decorator:

src/app/user.service.0.ts

import { Injectable } from '@angular/core';

@Injectable({
  providedIn: 'root',
})
export class UserService {
}

For newer versions of Laravel, please replace protected $redirectTo = RouteServiceProvider::HOME; with protected $redirectTo = '/newurl'; and replace newurl accordingly.

Tested with Laravel version-6

no you're just using it wrong. your is_number? has an argument. you called it without the argument

you should be doing is_number?(mystring)

Remove a block of code from multiple files

To expand on @Markus Olsson's answer, I needed to remove a block of code from multiple files. I had problems with Swedish characters in a core project, so I needed to install System.Text.CodePagesEncodingProvider nuget package and use System.Text.Encoding.GetEncoding(1252) instead of System.Text.Encoding.UTF8.

    public static void Main(string[] args)
    {
        try
        {
            var dir = @"C:\Test";
            //Get all html and htm files
            var files = DirSearch(dir);
            foreach (var file in files)
            {
                RmCode(file);
            }
        }
        catch (Exception e)
        {
            Console.WriteLine(e.Message);
            throw;
        }

    }

    private static void RmCode(string file)
    {
        string tempFile = Path.GetTempFileName();

        using (var sr = new StreamReader(file, Encoding.UTF8))
        using (var sw = new StreamWriter(new FileStream(tempFile, FileMode.Open, FileAccess.ReadWrite), Encoding.UTF8))
        {
            string line;

            var startOfBadCode = "<div>";
            var endOfBadCode = "</div>";
            var deleteLine = false;

            while ((line = sr.ReadLine()) != null)
            {
                if (line.Contains(startOfBadCode))
                {
                    deleteLine = true;
                }
                if (!deleteLine)
                {
                    sw.WriteLine(line);
                }

                if (line.Contains(endOfBadCode))
                {
                    deleteLine = false;
                }
            }
        }

        File.Delete(file);
        File.Move(tempFile, file);
    }

    private static List<String> DirSearch(string sDir)
    {
        List<String> files = new List<String>();
        try
        {
            foreach (string f in Directory.GetFiles(sDir))
            {
                files.Add(f);
            }
            foreach (string d in Directory.GetDirectories(sDir))
            {
                files.AddRange(DirSearch(d));
            }
        }
        catch (System.Exception excpt)
        {
            Console.WriteLine(excpt.Message);
        }

        return files.Where(s => s.EndsWith(".htm") || s.EndsWith(".html")).ToList();
    }

In your case it is probably taking them in DD-MM-YY format, not MM-DD-YY.

That would be:

b.rstrip('\n')

If you want to strip space from each and every line, you might consider instead:

a.read().splitlines()

This will give you a list of lines, without the line end characters.

Well yes arrays do exist, and no they're not different to lists when it comes to things like del and append:

>>> from array import array
>>> foo = array('i', range(5))
>>> foo
array('i', [0, 1, 2, 3, 4])
>>> del foo[:]
>>> foo
array('i')
>>> foo.append(42)
>>> foo
array('i', [42])
>>>

Differences worth noting: you need to specify the type when creating the array, and you save storage at the expense of extra time converting between the C type and the Python type when you do arr[i] = expression or arr.append(expression), and lvalue = arr[i]

I wrote this "C" function, because NSTask is obnoxious..

NSString * runCommand(NSString* c) {

    NSString* outP; FILE *read_fp;  char buffer[BUFSIZ + 1];
    int chars_read; memset(buffer, '\0', sizeof(buffer));
    read_fp = popen(c.UTF8String, "r");
    if (read_fp != NULL) {
        chars_read = fread(buffer, sizeof(char), BUFSIZ, read_fp);
        if (chars_read > 0) outP = $UTF8(buffer);
        pclose(read_fp);
    }   
    return outP;
}

NSLog(@"%@", runCommand(@"ls -la /")); 

total 16751
drwxrwxr-x+ 60 root        wheel     2108 May 24 15:19 .
drwxrwxr-x+ 60 root        wheel     2108 May 24 15:19 ..
…

oh, and for the sake of being complete / unambiguous…

#define $UTF8(A) ((NSString*)[NSS stringWithUTF8String:A])

Years later, C is still a bewildering mess, to me.. and with little faith in my ability to correct my gross shortcomings above - the only olive branch I offer is a rezhuzhed version of @inket's answer that is barest of bones, for my fellow purists / verbosity-haters...

id _system(id cmd) { 
   return !cmd ? nil : ({ NSPipe* pipe; NSTask * task;
  [task = NSTask.new setValuesForKeysWithDictionary: 
    @{ @"launchPath" : @"/bin/sh", 
        @"arguments" : @[@"-c", cmd],
   @"standardOutput" : pipe = NSPipe.pipe}]; [task launch];
  [NSString.alloc initWithData:
     pipe.fileHandleForReading.readDataToEndOfFile
                      encoding:NSUTF8StringEncoding]; });
}

From the information you have specified, your best chance of recovery is through a database backup. I don't think you're going to be able to rollback any of those changes you pushed through since you were apparently not using transactions at the time.

A lot of people have given some very technical answers for this and similar questions, but I think it's simpler than that. Sometimes if you're not paying attention a selector that you don't intend to use can be attached to something in the interface. You might be getting this error because the selector's there but you haven't written any code for it.

The easiest way to double-check that this is not the case is to control-click the item so you can see all of the selectors that are associated with it. If there's anything in there that you don't want to be, get rid of it! Hope this helps...

The solutions above seemed a little coupled and at the same time avoid reuse the same protocol in other controllers, that's why I've come with the solution that is more strong typed using generic type-erasure.

@noreturn public func notImplemented(){
    fatalError("not implemented yet")
}


public protocol DataChangedProtocol: class{
    typealias DataType

    func onChange(t:DataType)
}

class AbstractDataChangedWrapper<DataType> : DataChangedProtocol{

    func onChange(t: DataType) {
        notImplemented()
    }
}


class AnyDataChangedWrapper<T: DataChangedProtocol> : AbstractDataChangedWrapper<T.DataType>{

    var base: T

    init(_ base: T ){
        self.base = base
    }

    override func onChange(t: T.DataType) {
        base.onChange(t)
    }
}


class AnyDataChangedProtocol<DataType> : DataChangedProtocol{

    var base: AbstractDataChangedWrapper<DataType>

    init<S: DataChangedProtocol where S.DataType == DataType>(_ s: S){
        self.base = AnyDataChangedWrapper(s)
    }

    func onChange(t: DataType) {
        base.onChange(t)
    }
}



class Source : DataChangedProtocol {
    func onChange(data: String) {
        print( "got new value \(data)" )
    }
}


class Target {
    var delegate: AnyDataChangedProtocol<String>?

    func reportChange(data:String ){
        delegate?.onChange(data)
    }
}


var source = Source()
var target = Target()

target.delegate = AnyDataChangedProtocol(source)
target.reportChange("newValue")    

output: got new value newValue

if x is a vector with raw scores then scale(x) is a vector with standardized scores.

Or manually: (x-mean(x))/sd(x)

IMG elements are inline, meaning that unless they are floated they will flow horizontally with text and other inline elements.

They are "block" elements in that they have a width and a height. But they behave more like "inline-block" in that respect.

Easiest solution

<button type="button" onclick="window.location.href='{{ url_for( 'move_forward') }}';">Forward</button>

Try underscore-cli:

cat myfile.json | underscore print --color

It's a pretty nifty tool that can elegantly do a lot of manipulation of structured data, execute js snippets, fill templates, etc. It's ridiculously well documented, polished, and ready for serious use. And I wrote it. :)

These posts apparently are in the wrong order! This is #1 in a series of 3 posts. Sorry.

In attempting to use Lie Ryan's code, I had problems retrieving stored information. The vector's elements are not stored contiguously,as you can see by "cheating" a bit and storing the pointer to each element's address (which of course defeats the purpose of the dynamic array concept) and examining them.

With a bit of tinkering, via:

ss_vector* vector; // pull this out to be a global vector

// Then add the following to attempt to recover stored values.

int return_id_value(int i,apple* aa) // given ptr to component,return data item
{   printf("showing apple[%i].id = %i and  other_id=%i\n",i,aa->id,aa->other_id);
    return(aa->id);
}

int Test(void)  // Used to be "main" in the example
{   apple* aa[10]; // stored array element addresses
    vector = ss_init_vector(sizeof(apple));
    // inserting some items
    for (int i = 0; i < 10; i++)
    {   aa[i]=init_apple(i);
        printf("apple id=%i and  other_id=%i\n",aa[i]->id,aa[i]->other_id);
        ss_vector_append(vector, aa[i]);
     }   
 // report the number of components
 printf("nmbr of components in vector = %i\n",(int)vector->size);
 printf(".*.*array access.*.component[5] = %i\n",return_id_value(5,aa[5]));
 printf("components of size %i\n",(int)sizeof(apple));
 printf("\n....pointer initial access...component[0] = %i\n",return_id_value(0,(apple *)&vector[0]));
 //.............etc..., followed by
 for (int i = 0; i < 10; i++)
 {   printf("apple[%i].id = %i at address %i, delta=%i\n",i,    return_id_value(i,aa[i]) ,(int)aa[i],(int)(aa[i]-aa[i+1]));
 }   
// don't forget to free it
ss_vector_free(vector);
return 0;
}

It's possible to access each array element without problems, as long as you know its address, so I guess I'll try adding a "next" element and use this as a linked list. Surely there are better options, though. Please advise.

To get the right ownership, you can set the group setuid bit on the directory with

chmod g+rwxs dirname

This will ensure that files created in the directory are owned by the group. You should then make sure everyone runs with umask 002 or 007 or something of that nature---this is why Debian and many other linux systems are configured with per-user groups by default.

I don't know of a way to force the permissions you want if the user's umask is too strong.

# Original code
df = pd.DataFrame({'a': [1, 2, 3, 'bad', 5],
                   'b': [0.1, 0.2, 0.3, 0.4, 0.5],
                   'item': ['a', 'b', 'c', 'd', 'e']})
df = df.set_index('item')

Convert to numeric using 'coerce' which fills bad values with 'nan'

a = pd.to_numeric(df.a, errors='coerce')

Use isna to return a boolean index:

idx = a.isna()

Apply that index to the data frame:

df[idx]

output

Returns the row with the bad data in it:

        a    b
item          
d     bad  0.4

@all - everything in JavaScript is an object (), so statements like "only use this on objects" are a bit misleading. In addition JavaScript is not strongly typed so that 1 == "1" is true (although 1 === "1" is not, Crockford is big on this). When it comes to the progromatic concept of arrays in JS, typing is important in the definition.

@Brenton - No need to be a terminology dictator; "associative array", "dictionary", "hash", "object", these programming concepts all apply to one structure in JS. It is name (key, index) value pairs, where the value can be any other object (strings are objects too)

So, new Array() is the same as []

new Object() is roughly similar to {}

var myarray = [];

Creates a structure that is an array with the restriction that all indexes (aka keys) must be a whole number. It also allows for auto assigning of new indexes via .push()

var myarray = ["one","two","three"];

Is indeed best dealt with via for(initialization;condition;update){

But what about:

var myarray = [];
myarray[100] = "foo";
myarray.push("bar");

Try this:

var myarray = [], i;
myarray[100] = "foo";
myarray.push("bar");
myarray[150] = "baz";
myarray.push("qux");
alert(myarray.length);
for(i in myarray){
    if(myarray.hasOwnProperty(i)){  
        alert(i+" : "+myarray[i]);
    }
}

Perhaps not the best usage of an array, but just an illustration that things are not always clearcut.

If you know your keys, and definitely if they are not whole numbers, your only array like structure option is the object.

var i, myarray= {
   "first":"john",
   "last":"doe",
   100:"foo",
   150:"baz"
};
for(i in myarray){
    if(myarray.hasOwnProperty(i)){  
        alert(i+" : "+myarray[i]);
    }
}

update YourTable
    set YourColumn = replace(YourColumn, '@domain2', '@domain1')
    where charindex('@domain2', YourColumn) <> 0

Here is an easy and quick, presently available browser approach to creating folders inside a repository

1)Click the repository / create a new repository.

2)Click create Add file and then create a new file.

3)Give the folder name you want to create with a ' / ' mark and then add a file in it

4)Commit the changes

Edit 2014-09-30:

pandas now has a read_sql function. You definitely want to use that instead.

Original answer:

I can't help you with SQLAlchemy -- I always use pyodbc, MySQLdb, or psychopg2 as needed. But when doing so, a function as simple as the one below tends to suit my needs:

import pydobc
import numpy as np
import pandas

cnn, cur = myConnectToDBfunction()
cmd = "SELECT * FROM myTable"
cur.execute(cmd)
dataframe = __processCursor(cur, dataframe=True)

def __processCursor(cur, dataframe=False, index=None):
    '''
    Processes a database cursor with data on it into either
    a structured numpy array or a pandas dataframe.

    input:
    cur - a pyodbc cursor that has just received data
    dataframe - bool. if false, a numpy record array is returned
                if true, return a pandas dataframe
    index - list of column(s) to use as index in a pandas dataframe
    '''
    datatypes = []
    colinfo = cur.description
    for col in colinfo:
        if col[1] == unicode:
            datatypes.append((col[0], 'U%d' % col[3]))
        elif col[1] == str:
            datatypes.append((col[0], 'S%d' % col[3]))
        elif col[1] in [float, decimal.Decimal]:
            datatypes.append((col[0], 'f4'))

Surely the best way is to avoid doing any heavy HTML creation in your JavaScript at all? The markup sent down from the server ought to contain the bulk of it, which you can then manipulate, using CSS rather than brute force removing/replacing elements, if at all possible.

This doesn't apply if you're doing something "clever" like emulating a widget system.

This is not mentioned in you post but I suspect you are initiating an SSL connection from the browser to Apache, where VirtualHosts are configured, and Apache does a revese proxy to your Tomcat.

There is a serious bug in (some versions ?) of IE that sends the 'wrong' host information in an SSL connection (see EDIT below) and confuses the Apache VirtualHosts. In short the server name presented is the one of the reverse DNS resolution of the IP, not the one in the URL.

The workaround is to have one IP address per SSL virtual hosts/server name. Is short, you must end up with something like

1 server name == 1 IP address == 1 certificate == 1 Apache Virtual Host

EDIT

Though the conclusion is correct, the identification of the problem is better described here http://en.wikipedia.org/wiki/Server_Name_Indication

You can use HTML,

foreach(...)
echo $data1 . '&nbsp' . $data2 . '&nbsp' . $data3 . '<br/>';

First if the object you're dealing with is a string then you need to parse it then figure out the length of the keys :

obj = JSON.parse(jsonString);
shareInfoLen = Object.keys(obj.shareInfo[0]).length;

Here's a solution which will work even when JavaScript is disabled:

<form action="login.html">
    <button type="submit">Login</button>
</form>

The trick is to surround the button with its own <form> tag.

I personally prefer the <button> tag, but you can do it with <input> as well:

<form action="login.html">
    <input type="submit" value="Login"/>
</form>
