Mostly 301 vs 302 is important for indexing in search engines, as their crawlers take this into account and transfer PageRank when using 301.

See Peter Lee's answer for more details.

A 302 redirect means that the page was temporarily moved, while a 301 means that it was permanently moved.

301s are good for SEO value, while 302s aren't because 301s instruct clients to forget the value of the original URL, while the 302 keeps the value of the original and can thus potentially reduce the value by creating two, logically-distinct URLs that each produce the same content (search engines view them as distinct duplicates rather than a single resource with two names).

try this:

type: "GET",
async: false,
complete: function (XMLHttpRequest, textStatus) {
    var headers = XMLHttpRequest.getAllResponseHeaders();
}

You need to run the script like this:

groovy helloworld.groovy

You just compile it. In the bin\Release (or bin\Debug) folder, the .exe will be in there.

If you're asking how to make an executable which does not rely on the .NET framework at all, then that's a lot harder and you'll need to purchase something like RemoteSoft's Salamader. In general, it's not really worth the bother: Windows Vista comes with .NET framework 2.0 pre-installed already so if you're worried about that, you can just target the 2.0 framework (then only XP users would have to install the framework).

Two possible approaches.

1. If you have a foreign key, declare it as on-delete-cascade and delete the parent rows older than 30 days. All the child rows will be deleted automatically.

2. Based on your description, it looks like you know the parent rows that you want to delete and need to delete the corresponding child rows. Have you tried SQL like this?

     delete from child_table
         where parent_id in (
              select parent_id from parent_table
                   where updd_tms != (sysdate-30)
   

   -- now delete the parent table records

   delete from parent_table
   where updd_tms != (sysdate-30);
   

---- Based on your requirement, it looks like you might have to use PL/SQL. I'll see if someone can post a pure SQL solution to this (in which case that would definitely be the way to go).

declare
    v_sqlcode number;
    PRAGMA EXCEPTION_INIT(foreign_key_violated, -02291);
begin
    for v_rec in (select parent_id, child id from child_table
                         where updd_tms != (sysdate-30) ) loop

    -- delete the children
    delete from child_table where child_id = v_rec.child_id;

    -- delete the parent. If we get foreign key violation, 
    -- stop this step and continue the loop
    begin
       delete from parent_table
          where parent_id = v_rec.parent_id;
    exception
       when foreign_key_violated
         then null;
    end;
 end loop;
end;

Is it "safe" to use $_SERVER['HTTP_HOST'] for all links on a site without having to worry about XSS attacks, even when used in forms?

Yes, it's safe to use $_SERVER['HTTP_HOST'], (and even $_GET and $_POST) as long as you verify them before accepting them. This is what I do for secure production servers:

/* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * */
$reject_request = true;
if(array_key_exists('HTTP_HOST', $_SERVER)){
    $host_name = $_SERVER['HTTP_HOST'];
    // [ need to cater for `host:port` since some "buggy" SAPI(s) have been known to return the port too, see http://goo.gl/bFrbCO
    $strpos = strpos($host_name, ':');
    if($strpos !== false){
        $host_name = substr($host_name, $strpos);
    }
    // ]
    // [ for dynamic verification, replace this chunk with db/file/curl queries
    $reject_request = !array_key_exists($host_name, array(
        'a.com' => null,
        'a.a.com' => null,
        'b.com' => null,
        'b.b.com' => null
    ));
    // ]
}
if($reject_request){
    // log errors
    // display errors (optional)
    exit;
}
/* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * */
echo 'Hello World!';
// ...

The advantage of $_SERVER['HTTP_HOST'] is that its behavior is more well-defined than $_SERVER['SERVER_NAME']. Contrast ??:

Contents of the Host: header from the current request, if there is one.

with:

The name of the server host under which the current script is executing.

Using a better defined interface like $_SERVER['HTTP_HOST'] means that more SAPIs will implement it using reliable well-defined behavior. (Unlike the other.) However, it is still totally SAPI dependent ??:

There is no guarantee that every web server will provide any of these [$_SERVER entries]; servers may omit some, or provide others not listed here.

To understand how to properly retrieve the host name, first and foremost you need to understand that a server which contains only code has no means of knowing (pre-requisite for verifying) its own name on the network. It needs to interface with a component that supplies it its own name. This can be done via:

• local config file

• local database

• hardcoded source code

• external request (curl)

• client/attacker's Host: request

• etc

Usually its done via the local (SAPI) config file. Note that you have configured it correctly, e.g. in Apache ??:

A couple of things need to be 'faked' to make the dynamic virtual host look like a normal one.

The most important is the server name which is used by Apache to generate self-referential URLs, etc. It is configured with the ServerName directive, and it is available to CGIs via the SERVER_NAME environment variable.

The actual value used at run time is controlled by the UseCanonicalName setting.

With UseCanonicalName Off the server name comes from the contents of the Host: header in the request. With UseCanonicalName DNS it comes from a reverse DNS lookup of the virtual host's IP address. The former setting is used for name-based dynamic virtual hosting, and the latter is used for** IP-based hosting.

If Apache cannot work out the server name because there is no Host: header or the DNS lookup fails then the value configured with ServerName is used instead.

For people just migrating from java, In Kotlin List is by default immutable and mutable version of Lists is called MutableList.

Hence if you have something like :

val list: List<String> = ArrayList()

In this case you will not get an add() method as list is immutable. Hence you will have to declare a MutableList as shown below :

val list: MutableList<String> = ArrayList()

Now you will see an add() method and you can add elements to any list.

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

make -p

For instance:

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

which expands

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

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

C_INCLUDE_PATH=/usr/include

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

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

VPATH = my_dir_to_search

... or even more specific

vpath %.c src
vpath %.h include

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

We do a lot of work where we need to figure out which IP's are within certain subnets. I've found that the simplest and most reliable way to do this is:

1. Add a field to each table called IPInteger (bigint) (when invalid, set IP= '0.0.0.0')
2. For smaller tables, I use a trigger that updates IPInteger on change
3. For larger tables, I use a SPROC to refresh the IPIntegers

    ALTER FUNCTION [dbo].[IP_To_INT ]
    ( 
        @IP CHAR(15) 
    ) 
    RETURNS BIGINT 
    AS 
    BEGIN 
        DECLARE @IntAns BIGINT, 
            @block1 BIGINT, 
            @block2 BIGINT, 
            @block3 BIGINT, 
            @block4 BIGINT, 
            @base BIGINT 
     
        SELECT 
            @block1 = CONVERT(BIGINT, PARSENAME(@IP, 4)), 
            @block2 = CONVERT(BIGINT, PARSENAME(@IP, 3)), 
            @block3 = CONVERT(BIGINT, PARSENAME(@IP, 2)), 
            @block4 = CONVERT(BIGINT, PARSENAME(@IP, 1)) 
     
        IF (@block1 BETWEEN 0 AND 255) 
            AND (@block2 BETWEEN 0 AND 255) 
            AND (@block3 BETWEEN 0 AND 255) 
            AND (@block4 BETWEEN 0 AND 255) 
        BEGIN      
            SET @base = CONVERT(BIGINT, @block1 * 16777216)
            SET @IntAns = @base +  
                (@block2 * 65536) +  
                (@block3 * 256) + 
                (@block4) 
        END 
        ELSE 
            SET @IntAns = -1 
        RETURN @IntAns 
    END

Visual Studio reads NuGet.Config files from the solution root. Try moving it there instead of placing it in the same folder as the project.

You can also place the file at %appdata%\NuGet\NuGet.Config and it will be used everywhere.

An md5 encryption is one of the worst, because you have to turn the code and it is already decrypted. I would recommend you the SHA256. I'm programming a bit longer and have had a good experience. Below would also be an encryption.

password_hash() example using Argon2i

<?php
echo 'Argon2i hash: ' . password_hash('rasmuslerdorf', PASSWORD_ARGON2I);

I got the same error when the script file I was including container some special characters and when I was running in local moode (directly from local disk). I my case the solution was to explicitly tell the encoding:

Slug is a URL friendly short label for specific content. It only contain Letters, Numbers, Underscores or Hyphens. Slugs are commonly save with the respective content and it pass as a URL string.

Slug can create using SlugField

Ex:

class Article(models.Model):
    title = models.CharField(max_length=100)
    slug = models.SlugField(max_length=100)

If you want to use title as slug, django has a simple function called slugify

from django.template.defaultfilters import slugify

class Article(models.Model):
    title = models.CharField(max_length=100)

    def slug(self):
        return slugify(self.title)

If it needs uniqueness, add unique=True in slug field.

for instance, from the previous example:

class Article(models.Model):
    title = models.CharField(max_length=100)
    slug = models.SlugField(max_length=100, unique=True)

Are you lazy to do slug process ? don't worry, this plugin will help you. django-autoslug

Do you have concurrency, i.e simultaneous users ? If you just run 1000 times the query straight, with just one thread, there will be almost no difference. Too easy for these engines :)

BUT I strongly suggest that you build a true load testing session, which means using an injector such as JMeter with 10, 20 or 50 users AT THE SAME TIME so you can really see a difference (try to embed this code inside a web page JMeter could query).

I just did it today on a single server (and a simple collection / table) and the results are quite interesting and surprising (MongoDb was really faster on writes & reads, compared to MyISAM engine and InnoDb engine).

This really should be part of your test : concurrency & MySQL engine. Then, data/schema design & application needs are of course huge requirements, beyond response times. Let me know when you get results, I'm also in need of inputs about this!

Generally speaking, it's recommended to use MSI-based installations on Windows. Thus, if you're ready to invest a fair bit of time, WiX is the way to go.

If you want something which is much more simpler, go with InnoSetup.

You typically restore purchases with this code:

[[SKPaymentQueue defaultQueue] restoreCompletedTransactions];

It will reinvoke -paymentQueue:updatedTransactions on the observer(s) for the purchased items. This is useful for users who reinstall the app after deletion or install it on a different device.

Not all types of In-App purchases can be restored.

Think of it like an archive. MyDB.Bak contains MyDB.mdf and MyDB.ldf.

Restore with Move to say HerDB basically grabs MyDB.mdf (and ldf) from the back up, and copies them as HerDB.mdf and ldf.

So if you already had a MyDb on the server instance you are restoring to it wouldn't be touched.

I had the same problem and here is my solution (very humble, @george: this time compiling AND working ...).

My probem was inside an abstract class that implements Observer. The Observable fires method update(...) with Object class that can be any kind of Object.

I only want to handler Objects of type T

The solution is to pass the class to the constructor in order to be able to compare types at runtime.

public abstract class AbstractOne<T> implements Observer {

  private Class<T> tClass;
    public AbstractOne(Class<T> clazz) {
    tClass = clazz;
  }

  @Override
  public void update(Observable o, Object arg) {
    if (tClass.isInstance(arg)) {
      // Here I am, arg has the type T
      foo((T) arg);
    }
  }

  public abstract foo(T t);

}

For the implementation we just have to pass the Class to the constructor

public class OneImpl extends AbstractOne<Rule> {
  public OneImpl() {
    super(Rule.class);
  }

  @Override
  public void foo(Rule t){
  }
}

If you have copied the seeders files from any other project then you need to run the artisan command php artisan db:seed otherwise it is fine.

Remove onsubmit from the form tag. Change this:

<input type="submit" value="submit" />

To:

<input type="submit" value="submit" name='btnSub' />

And write this:

if(isset($_POST['btnSub']))
    echo "<script>window.close();</script>";

Look if the package have an official fork that include the necessary binary wheels.

I needed the package python-Levenshtein, had this error, and find the package python-Levenshtein-wheels instead.

While Dav is correct that the information isn't directly stored, that doesn't mean you can't ever find out. Here are a few things you can do.

Find branches the commit is on

git branch -a --contains <commit>

This will tell you all branches which have the given commit in their history. Obviously this is less useful if the commit's already been merged.

Search the reflogs

If you are working in the repository in which the commit was made, you can search the reflogs for the line for that commit. Reflogs older than 90 days are pruned by git-gc, so if the commit's too old, you won't find it. That said, you can do this:

git reflog show --all | grep a871742

to find commit a871742. Note that you MUST use the abbreviatd 7 first digits of the commit. The output should be something like this:

a871742 refs/heads/completion@{0}: commit (amend): mpc-completion: total rewrite

indicating that the commit was made on the branch "completion". The default output shows abbreviated commit hashes, so be sure not to search for the full hash or you won't find anything.

git reflog show is actually just an alias for git log -g --abbrev-commit --pretty=oneline, so if you want to fiddle with the output format to make different things available to grep for, that's your starting point!

If you're not working in the repository where the commit was made, the best you can do in this case is examine the reflogs and find when the commit was first introduced to your repository; with any luck, you fetched the branch it was committed to. This is a bit more complex, because you can't walk both the commit tree and reflogs simultaneously. You'd want to parse the reflog output, examining each hash to see if it contains the desired commit or not.

Find a subsequent merge commit

This is workflow-dependent, but with good workflows, commits are made on development branches which are then merged in. You could do this:

git log --merges <commit>..

to see merge commits that have the given commit as an ancestor. (If the commit was only merged once, the first one should be the merge you're after; otherwise you'll have to examine a few, I suppose.) The merge commit message should contain the branch name that was merged.

If you want to be able to count on doing this, you may want to use the --no-ff option to git merge to force merge commit creation even in the fast-forward case. (Don't get too eager, though. That could become obfuscating if overused.) VonC's answer to a related question helpfully elaborates on this topic.

Select the System.Web.Mvc assembly in the "References" folder in the solution explorer. Bring up the properties window (F4) and check the Version

I had a similar problem when trying to use boost unit testing in Visual Studio 2015 (Community Edition):

fatal error LNK1104: libboost_unit_test_framework-vc140-mt-1_57

so I thought I'd share my solution.

You can create a boost unit testing project in of of two ways (and this solution works for both):

1. using the Boost Unit Test Adapter
2. or by creating a Win32 Console Application (steps here), and substituting the main function with a boost unit testing function (steps here).

Here are the steps I followed to get both projects to work:

First, download the desired boost version (for example, boost_1_57_0). You can either download boost with the correct binaries (compiled using msvc v140), or extract the binaries yourself by running the following commands from command line:

1. bootstrap.bat
2. "C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\vcvarsall.bat" x86
3. bjam --clean
4. bjam -j4 --debug-symbols=on --build-type=complete toolset=msvc-14.0 threading=multi runtime-link=shared address-model=32

Where msvc-14.0 specifies that we require the Visual Studio 2015 version (VS 2015 = v14.0 = v140), and address-model=32 specifies that we require platform 32 (but the same can be done for 64 bit).

Once you have the binaries, go to Visual Studio, select the Boost Unit Testing project you have created. Go to Project properties > configuration (from the main menu) and make the following choices:

• Set the "General > Platform Toolset" to Visual Studio 2015 (v140).

• Include the path to the boost folder (e.g. C:\boost_1_57_0) and the path to the subfolder containing the binary files (e.g. C:\boost_1_57_0\stage\lib) in:

  • "C\C++ > Additional Include Directory"
  • and "Linker > Additional Library Directories".

tl;dr Set the editor to something nicer, like Sublime or Atom

Here nice is used in the meaning of an editor you like or find more user friendly.

The underlying problem is that Git by default uses an editor that is too unintuitive to use for most people: Vim. Now, don't get me wrong, I love Vim, and while you could set some time aside (like a month) to learn Vim and try to understand why some people think Vim is the greatest editor in existence, there is a quicker way of fixing this problem :-)

The fix is not to memorize cryptic commands, like in the accepted answer, but configuring Git to use an editor that you like and understand! It's really as simple as configuring either of these options

1. the git config setting core.editor (per project, or globally)
2. the VISUAL or EDITOR environment variable (this works for other programs as well)

I'll cover the first option for a couple of popular editors, but GitHub has an excellent guide on this for many editors as well.

To use Atom

Straight from its docs, enter this in a terminal: git config --global core.editor "atom --wait"

Git normally wait for the editor command to finish, but since Atom forks to a background process immediately, this won't work, unless you give it the --wait option.

To use Sublime Text

For the same reasons as in the Atom case, you need a special flag to signal to the process that it shouldn't fork to the background:

git config --global core.editor "subl -n -w"

My problem and the solution

1. I have a 32 bit third party dll which I have installed in 2008 R2 machine which is 64 bit.

2. I have a wcf service created in .net 4.5 framework which calls the 32 bit third party dll for process. Now I have build property set to target 'any' cpu and deployed it to the 64 bit machine.

3. When Ii tried to invoke the wcf service got error "80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG"

4. Now Ii used ProcMon.exe to trace the com registry issue and identified that the process is looking for the registry entry at HKLM\CLSID and HKCR\CLSID where there is no entry.

5. Came to know that Microsoft will not register the 32 bit com components to the paths HKLM\CLSID, HKCR\CLSID in 64 bit machine rather it places the entry in HKLM\Wow6432Node\CLSID and HKCR\Wow6432Node\CLSID paths.

6. Now the conflict is 64 bit process trying to invoke 32 bit process in 64 bit machine which will look for the registry entry in HKLM\CLSID, HKCR\CLSID. The solution is we have to force the 64 bit process to look at the registry entry at HKLM\Wow6432Node\CLSID and HKCR\Wow6432Node\CLSID.

7. This can be achieved by configuring the wcf service project properties to target to 'X86' machine instead of 'Any'.

8. After deploying the 'X86' version to the 2008 R2 server got the issue "System.BadImageFormatException: Could not load file or assembly"

9. Solution to this badimageformatexception is setting the 'Enable32bitApplications' to 'True' in IIS Apppool properties for the right apppool.

To elaborate on Ben's answer:

If you add a reference to Microsoft Scripting Runtime and correctly type the variable fso you can take advantage of autocompletion (Intellisense) and discover the other great features of FileSystemObject.

Here is a complete example module:

Option Explicit

' Go to Tools -> References... and check "Microsoft Scripting Runtime" to be able to use
' the FileSystemObject which has many useful features for handling files and folders
Public Sub SaveTextToFile()

    Dim filePath As String
    filePath = "C:\temp\MyTestFile.txt"

    ' The advantage of correctly typing fso as FileSystemObject is to make autocompletion
    ' (Intellisense) work, which helps you avoid typos and lets you discover other useful
    ' methods of the FileSystemObject
    Dim fso As FileSystemObject
    Set fso = New FileSystemObject
    Dim fileStream As TextStream

    ' Here the actual file is created and opened for write access
    Set fileStream = fso.CreateTextFile(filePath)

    ' Write something to the file
    fileStream.WriteLine "something"

    ' Close it, so it is not locked anymore
    fileStream.Close

    ' Here is another great method of the FileSystemObject that checks if a file exists
    If fso.FileExists(filePath) Then
        MsgBox "Yay! The file was created! :D"
    End If

    ' Explicitly setting objects to Nothing should not be necessary in most cases, but if
    ' you're writing macros for Microsoft Access, you may want to uncomment the following
    ' two lines (see https://stackoverflow.com/a/517202/2822719 for details):
    'Set fileStream = Nothing
    'Set fso = Nothing

End Sub

I just fund another way to do the same workaround. Because of I hadn' t the possibility to click on the yellow triangle (even if I have admin role), when you go inside testflight, then iOS (under "Build") instead of yellow triangle click the version number, another page will open and you will find on top right something like add compliance information (sorry if I am not totally accurate but I have the italian version but it would be really easy to find). Then you can do the same even if you, like me, are not able to click on yellow triangle.

A wild idea, try parsing it and catch the exception:

import org.json.*;

public boolean isJSONValid(String test) {
    try {
        new JSONObject(test);
    } catch (JSONException ex) {
        // edited, to include @Arthur's comment
        // e.g. in case JSONArray is valid as well...
        try {
            new JSONArray(test);
        } catch (JSONException ex1) {
            return false;
        }
    }
    return true;
}

This code uses org.json JSON API implementation that is available on github, in maven and partially on Android.

Like this:

>>> s='1\t2\t3\t4\t5'
>>> [x for x in s.split('\t')]
['1', '2', '3', '4', '5']

For a file:

# create test file:
>>> with open('tabs.txt','w') as o:
...    s='\n'.join(['\t'.join(map(str,range(i,i+10))) for i in [0,10,20,30]])
...    print >>o, s

#read that file:
>>> with open('tabs.txt','r') as f:
...    LoL=[x.strip().split('\t') for x in f]
... 
>>> LoL
[['0', '1', '2', '3', '4', '5', '6', '7', '8', '9'], 
 ['10', '11', '12', '13', '14', '15', '16', '17', '18', '19'], 
 ['20', '21', '22', '23', '24', '25', '26', '27', '28', '29'], 
 ['30', '31', '32', '33', '34', '35', '36', '37', '38', '39']]
>>> LoL[2][3]
23

If you want the input transposed:

>>> with open('tabs.txt','r') as f:
...    LoT=zip(*(line.strip().split('\t') for line in f))
... 
>>> LoT[2][3]
'32'

Or (better still) use the csv module in the default distribution...

You can use DataFrame.select_dtypes to select string columns and then apply function str.strip.

Notice: Values cannot be types like dicts or lists, because their dtypes is object.

df_obj = df.select_dtypes(['object'])
print (df_obj)
0    a  
1    c  

df[df_obj.columns] = df_obj.apply(lambda x: x.str.strip())
print (df)

   0   1
0  a  10
1  c   5

But if there are only a few columns use str.strip:

df[0] = df[0].str.strip()

The XLSB format is also dedicated to the macros embeded in an hidden workbook file located in excel startup folder (XLSTART).

A quick & dirty test with a xlsm or xlsb in XLSTART folder:

Measure-Command { $x = New-Object -com Excel.Application ;$x.Visible = $True ; $x.Quit() }

0,89s with a xlsb (binary) versus 1,3s with the same content in xlsm format (xml in a zip file) ... :)

It's not that your file is partially downloaded. It fails authentication and hence downloads e.g "index.html" but it names it myfile.zip (since this is what you want to download).

I followed the link suggested by @thomasbabuj and figured it out eventually.

You should try adding --auth-no-challenge and as @thomasbabuj suggested replace your password entry

I.e

wget --auth-no-challenge --user=myusername --ask-password https://test.mydomain.com/files/myfile.zip

There is no other way to do it other than what you described. Think about it - how can anyone know what classes extend ClassX without scanning each class on the classpath?

Eclipse can only tell you about the super and subclasses in what seems to be an "efficient" amount of time because it already has all of the type data loaded at the point where you press the "Display in Type Hierarchy" button (since it is constantly compiling your classes, knows about everything on the classpath, etc).

I needed the same functionality, and doing jailbreak is no-no. One solution is to host yourself DNS server (MaraDNS), go to your wifi settings in ipad/phone, and add your custom DNS server there.

The whole process took me only 10 minutes, and it works!

1) Download MaraDNS

2) Run mkSecretTxt.exe as administrator

3) Modify mararc file, mine is:

ipv4_bind_addresses = "put your public IP Here"
timestamp_type = 2
random_seed_file = "secret.txt"

csv2 = {}
csv2["Simple.Example.com."] = "example.configuration"

Add file called "example.configuration" into the same folder where run_maradns.bat is.

4) Edit your example.configuration file:

Simple.Example.com. 10.10.13.13 ~

5) Disable all Firewalls (convenience)

6) Run file "run_maradns.bat"

7) There should be no errors.

8) Add your DNS server to list, as shown here: http://www.iphonehacks.com/2014/08/change-dns-iphone-ipad.html

9) Works!

document.getElementById("serverTime").innerHTML = ...;

HttpWebRequest webRequest = WebRequest.Create(uirTradeStream) as HttpWebRequest;

webRequest.Proxy = WebRequest.DefaultWebProxy;

webRequest.Credentials = new NetworkCredential("user", "password");

webRequest.Proxy.Credentials = new NetworkCredential("user", "password");

It is successful.

If you are using python elasticsearch5 module or curl:

1. make sure each document that gets inserted has
   • a timestamp field that is type datetime
   • and you are monotonically increasing the timestamp value for each document

2. from python you do

   es = elasticsearch5.Elasticsearch('my_host:my_port')
   es.search(
       index='my_index', 
       size=1,
       sort='my_timestamp:desc'
       )
   

If your documents are not inserted with any field that is of type datetime, then I don't believe you can get the N "most recent".

Here's a couple of suggestions:

Use date_range for the index:

import datetime
import pandas as pd
import numpy as np

todays_date = datetime.datetime.now().date()
index = pd.date_range(todays_date-datetime.timedelta(10), periods=10, freq='D')

columns = ['A','B', 'C']

Note: we could create an empty DataFrame (with NaNs) simply by writing:

df_ = pd.DataFrame(index=index, columns=columns)
df_ = df_.fillna(0) # with 0s rather than NaNs

To do these type of calculations for the data, use a numpy array:

data = np.array([np.arange(10)]*3).T

Hence we can create the DataFrame:

In [10]: df = pd.DataFrame(data, index=index, columns=columns)

In [11]: df
Out[11]: 
            A  B  C
2012-11-29  0  0  0
2012-11-30  1  1  1
2012-12-01  2  2  2
2012-12-02  3  3  3
2012-12-03  4  4  4
2012-12-04  5  5  5
2012-12-05  6  6  6
2012-12-06  7  7  7
2012-12-07  8  8  8
2012-12-08  9  9  9

Per Arvand:
Eclipse: Simply type android.R.layout.simple_list_item_1 somewhere in code, hold Ctrl, hover over simple_list_item_1, and from the dropdown that appears select Open declaration in layout/simple_list_item_1.xml. It'll direct you to the contents of the XML.

From there, if you then hover over the resulting simple_list_item_1.xml tab in the Editor, you'll see the file is located at C:\Data\applications\Android\android-sdk\platforms\android-19\data\res\layout\simple_list_item_1.xml (or equivalent location for your installation).

jQuery's .trigger('click'); will only cause an event to trigger on this event, it will not trigger the default browser action as well.

You can simulate the same functionality with the following JavaScript:

jQuery('#foo').on('click', function(){
    var bar = jQuery('#bar');
    var href = bar.attr('href');
    if(bar.attr("target") === "_blank")
    {
        window.open(href);
    }else{
        window.location = href;
    }
});

Use "\n" instead of '\n'

I think you will want to use ThreadSafeClientConnManager.

You can see how it works here: http://foo.jasonhudgins.com/2009/08/http-connection-reuse-in-android.html

Or in the AndroidHttpClient which uses it internally.

PhpStorm 2020

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

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

3. File -> Invalidate / Restart -> Restart

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

To edit this file for any version of Idea

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

Did you enable the session state in the section as well?

 <system.web>
      <pages enableSessionState="true" /> 
 </system.web>

Or did you add this to the page?

 <%@Page enableSessionState="true"> 

And did you verify that the ASP.NET Session State Manager Service service is running? In your screenshot it isn't. It's set to start-up mode Manual which requires you to start it every time you want to make use of it. To start it, highlight the service and click the green play button on the toolbar. To start it automatically, edit the properties and adjust the Start-up type.

Or set the SessionState's mode property to InProc, so that the state service is not required.

 <system.web>
      <sessionState mode="InProc" />
 </system.web>

Check MSDN for all the options available to you with regards to storing data in the ASP.NET session state.

Note: It's better to have your Controller fetch the value from the session and have it add the value to the Model for your page/control (or to the ViewBag), that way the View doesn't depend on the HttpSession and you can choose a different source for this item later with minimal code changes. Or even better, not use the session state at all. It can kill you performance when you're using a lot of async javascript calls.

See the section "5.1. Accessing Hibernate APIs from JPA" in the Hibernate ORM User Guide:

Session session = entityManager.unwrap(Session.class);

The "in" in Linq-To-Sql uses a reverse logic compared to a SQL query.

Let's say you have a list of integers, and want to find the items that match those integers.

int[] numbers = new int[] { 1, 2, 3, 4, 5, 6, 7, 8, 9 };

var items = from p in context.Items
                 where numbers.Contains(p.ItemId)
                select p;

Anyway, the above works fine in linq-to-sql but not in EF 1.0. Haven't tried it in EF 4.0

use global scope on your $con and put it inside your getPosts() function like so.

function getPosts() {
global $con;
$query = mysqli_query($con,"SELECT * FROM Blog");
while($row = mysqli_fetch_array($query))
    {
        echo "<div class=\"blogsnippet\">";
        echo "<h4>" . $row['Title'] . "</h4>" . $row['SubHeading'];
        echo "</div>";
    }
}

Yes, that is safe and recommended.

The only caveat from the page you referred is that you can't be modifying configuration of the mapper once it is shared; but you are not changing configuration so that is fine. If you did need to change configuration, you would do that from the static block and it would be fine as well.

EDIT: (2013/10)

With 2.0 and above, above can be augmented by noting that there is an even better way: use ObjectWriter and ObjectReader objects, which can be constructed by ObjectMapper. They are fully immutable, thread-safe, meaning that it is not even theoretically possible to cause thread-safety issues (which can occur with ObjectMapper if code tries to re-configure instance).

Use SpecialCells to delete only the rows that are visible after autofiltering:

ActiveSheet.Range("$A$1:$I$" & lines).SpecialCells _
    (xlCellTypeVisible).EntireRow.Delete

If you have a header row in your range that you don't want to delete, add an offset to the range to exclude it:

ActiveSheet.Range("$A$1:$I$" & lines).Offset(1, 0).SpecialCells _
    (xlCellTypeVisible).EntireRow.Delete

My vote would be to name it IsLast and change the functionality. If that isn't really an option, I'd leave the name as IsNotLast.

I agree with Code Complete (Use positive boolean variable names), I also believe that rules are made to be broken. The key is to break them only when you absoluately have to. In this case, none of the alternative names are as clear as the name that "breaks" the rule. So this is one of those times where breaking the rule can be okay.

You're obviously not closing your file descriptors before opening new ones. Are you on windows or linux?

I take no issue with the accepted answer as it certainly helped me. However, after implementing it, I still got the same error.

Turns out this was because I was calling the pipes incorrectly in my component as well:

My custom-pipe.ts file:

@Pipe({ name: 'doSomething' })
export class doSomethingPipe implements PipeTransform {
    transform(input: string): string {
        // Do something
    }
}

So far, so good, but in my component.html file I was calling the pipes as follows:

{{ myData | doSomethingPipe }}

This will again throw the error that the pipe is not found. This is because Angular looks up the pipes by the name defined in the Pipe decorator. So in my example, the pipe should instead be called like this:

{{ myData | doSomething }}

Silly mistake, but it cost me a fair amount of time. Hope this helps!

this answers not working for new updated intelliJ... for new intelliJ..

Go to --> file --> Project Structure --> Global Libraries ==> set to JDK 1.8 or higher version.

also File -- > project Structure ---> projects ===> set "project language manual" to 8

This should enable lambda expression for your project.

I'm surprised import from es6 has not been mentioned (use with small files)

Ex: import test from './test.json'

webpack 2< uses the json-loader as default for .json files.

https://webpack.js.org/guides/migrating/#json-loader-is-not-required-anymore

For TypeScript:

import test from 'json-loader!./test.json';

TS2307 (TS) Cannot find module 'json-loader!./suburbs.json'

To get it working I had to declare the module first. I hope this will save a few hours for someone.

declare module "json-loader!*" {
  let json: any;
  export default json;
}

...

import test from 'json-loader!./test.json';

If I tried to omit loader from json-loader I got the following error from webpack:

BREAKING CHANGE: It's no longer allowed to omit the '-loader' suffix when using loaders. You need to specify 'json-loader' instead of 'json', see https://webpack.js.org/guides/migrating/#automatic-loader-module-name-extension-removed

You can do so by creating an array of dtype=object. If you try to assign a long string to a normal numpy array, it truncates the string:

>>> a = numpy.array(['apples', 'foobar', 'cowboy'])
>>> a[2] = 'bananas'
>>> a
array(['apples', 'foobar', 'banana'], 
      dtype='|S6')

But when you use dtype=object, you get an array of python object references. So you can have all the behaviors of python strings:

>>> a = numpy.array(['apples', 'foobar', 'cowboy'], dtype=object)
>>> a
array([apples, foobar, cowboy], dtype=object)
>>> a[2] = 'bananas'
>>> a
array([apples, foobar, bananas], dtype=object)

Indeed, because it's an array of objects, you can assign any kind of python object to the array:

>>> a[2] = {1:2, 3:4}
>>> a
array([apples, foobar, {1: 2, 3: 4}], dtype=object)

However, this undoes a lot of the benefits of using numpy, which is so fast because it works on large contiguous blocks of raw memory. Working with python objects adds a lot of overhead. A simple example:

>>> a = numpy.array(['abba' for _ in range(10000)])
>>> b = numpy.array(['abba' for _ in range(10000)], dtype=object)
>>> %timeit a.copy()
100000 loops, best of 3: 2.51 us per loop
>>> %timeit b.copy()
10000 loops, best of 3: 48.4 us per loop

Answering my own question here... turns out it's a Windows only quirk that happens when reading binary files (in my case a JPEG) that requires an additional flag in the open or File.open function call. I revised it to open("/path/to/file", 'rb') {|io| a = a + io.read} and all was fine.

If you are planning on doing any kind of inheritance, then I would recommend this.constructor. This simple example should illustrate why:

class ConstructorSuper {
  constructor(n){
    this.n = n;
  }

  static print(n){
    console.log(this.name, n);
  }

  callPrint(){
    this.constructor.print(this.n);
  }
}

class ConstructorSub extends ConstructorSuper {
  constructor(n){
    this.n = n;
  }
}

let test1 = new ConstructorSuper("Hello ConstructorSuper!");
console.log(test1.callPrint());

let test2 = new ConstructorSub("Hello ConstructorSub!");
console.log(test2.callPrint());

• test1.callPrint() will log ConstructorSuper Hello ConstructorSuper! to the console
• test2.callPrint() will log ConstructorSub Hello ConstructorSub! to the console

The named class will not deal with inheritance nicely unless you explicitly redefine every function that makes a reference to the named Class. Here is an example:

class NamedSuper {
  constructor(n){
    this.n = n;
  }

  static print(n){
    console.log(NamedSuper.name, n);
  }

  callPrint(){
    NamedSuper.print(this.n);
  }
}

class NamedSub extends NamedSuper {
  constructor(n){
    this.n = n;
  }
}

let test3 = new NamedSuper("Hello NamedSuper!");
console.log(test3.callPrint());

let test4 = new NamedSub("Hello NamedSub!");
console.log(test4.callPrint());

• test3.callPrint() will log NamedSuper Hello NamedSuper! to the console
• test4.callPrint() will log NamedSuper Hello NamedSub! to the console

See all the above running in Babel REPL.

You can see from this that test4 still thinks it's in the super class; in this example it might not seem like a huge deal, but if you are trying to reference member functions that have been overridden or new member variables, you'll find yourself in trouble.

I ran into this problem recently - the issue was that I had included the jQuery UI files in the head tag, but the Telerik library I was using included jQuery at the bottom of the body tag (thus apparently re-initializing jQuery and unloading the UI plugins previously loaded).

The solution was to find out where jQuery was actually being included, and including the jQuery UI scripts after that.

A standard approach/workaround/solution is to add a class object to the constructor(s), like:

 public class Foo<T> {

    private Class<T> type;
    public Foo(Class<T> type) {
      this.type = type;
    }

    public Class<T> getType() {
      return type;
    }

    public T newInstance() {
      return type.newInstance();
    }
 }

This will also change it into an array:

<?php
    print_r((array) json_decode($object));
?>

I had the same problem and nothing mentioned here worked for me. Here is what worked for me:

1. Require all dependencies you need in the main.js file that is run by electron. (this seemed to be the first important part for me)
2. Run npm i -D electron-rebuild to add the electron-rebuild package
3. Remove the node-modules folder, as well as the packages-lock.json file.
4. Run npm i to install all modules.
5. Run ./node_modules/.bin/electron-rebuild (.\node_modules\.bin\electron-rebuild.cmd for Windows) to rebuild everything

It is very important to run ./node_modules/.bin/electron-rebuild directly after npm i otherwise it did not work on my mac.

I hope I could help some frustrated souls.

Use the below class to Generate a Salt first. Each user needs to have a different salt, we can save it in the database along with the other user properties. The rounds value decides the number of times the password will be hashed.

For more details: https://docs.microsoft.com/en-us/dotnet/api/system.security.cryptography.rfc2898derivebytes.-ctor?view=netcore-3.1#System_Security_Cryptography_Rfc2898DeriveBytes__ctor_System_Byte___System_Byte___System_Int32_

public class HashSaltWithRounds
{
    int saltLength = 32;
    public byte[] GenerateSalt()
    {
        using (var randomNumberGenerator = new RNGCryptoServiceProvider())
        {
            var randomNumber = new byte[saltLength];
            randomNumberGenerator.GetBytes(randomNumber);
            return randomNumber;
        }
    }

    public string HashDataWithRounds(byte[] password, byte[] salt, int rounds)
    {
        using(var rfc2898= new Rfc2898DeriveBytes(password, salt, rounds))
        {
            return Convert.ToBase64String(rfc2898.GetBytes(32));
        }
    }
}

We can call it from a console application as follows. I have hashed the password twice using the same salt.

public class Program
{
    public static void Main(string[] args)
    {
        int numberOfIterations = 99;
        var hashFunction = new HashSaltWithRounds();

        string password = "Your Password Here";
        byte[] salt = hashFunction.GenerateSalt();

        var hashedPassword1 = hashFunction.HashDataWithRounds(Encoding.UTF8.GetBytes(password), salt, numberOfIterations);
        var hashedPassword2 = hashFunction.HashDataWithRounds(Encoding.UTF8.GetBytes(password), salt, numberOfIterations);

        Console.WriteLine($"hashedPassword1 :{hashedPassword1}");
        Console.WriteLine($"hashedPassword2 :{hashedPassword2}");
        Console.WriteLine(hashedPassword1.Equals(hashedPassword2));

        Console.ReadLine();

    }
}

You need to create a service to be able to share data between controllers.

app.factory('myService', function() {
 var savedData = {}
 function set(data) {
   savedData = data;
 }
 function get() {
  return savedData;
 }

 return {
  set: set,
  get: get
 }

});

In your controller A:

myService.set(yourSharedData);

In your controller B:

$scope.desiredLocation = myService.get();

Remember to inject myService in the controllers by passing it as a parameter.

We use Quack to pull a specific module from another Git repository. We need to pull code without the whole code base of the provided repository - we need a very specific module / file from that huge repository and should be updated every time we run update.

So we achieved it in this way:

Create configuration

name: Project Name

modules:
  local/path:
    repository: https://github.com/<username>/<repo>.git
    path: repo/path
    branch: dev
  other/local/path/filename.txt:
    repository: https://github.com/<username>/<repo>.git
    hexsha: 9e3e9642cfea36f4ae216d27df100134920143b9
    path: repo/path/filename.txt

profiles:
  init:
    tasks: ['modules']

With the above configuration, it creates one directory from the provided GitHub repository as specified in first module configuration, and the other one is to pull and create a file from the given repository.

Other developers just need to run

$ quack

And it pulls the code from the above configurations.

If using Windows as host, you can use WinSCP to connect to Docker and transfer files through the GUI.

If on Linux, the scp command would also work through the terminal.

I'm not allowed to comment, so regarding Shane's answer, keep in mind that

wp_localize_scripts()

must be hooked to wp or admin enqueue scripts. So a good example would be as follows:

function local() {

    wp_localize_script( 'js-file-handle', 'ajax', array(
        'url' => admin_url( 'admin-ajax.php' )
    ) );

}

add_action('admin_enqueue_scripts', 'local');
add_action('wp_enqueue_scripts', 'local');`

Linear scrolling animation to bottom. Pure JS, no JQuery. Maybe my solution will be helpful for someone.

let action_count = 8;
let speed_ms = 15;
let objDiv = document.getElementsByClassName('js_y5_area3').item(0);

let scroll_height = objDiv.scrollHeight;
let window_height = objDiv.offsetHeight;

let scroll_top = objDiv.scrollTop;
let need_scroll_top = scroll_height - window_height;

if (scroll_top < need_scroll_top)
{
    let step = Math.ceil((need_scroll_top - scroll_top) / action_count);

    let scrollInterval = setInterval(function()
    {
        scroll_top += step;
        objDiv.scrollTop = scroll_top;

        if (scroll_top >= need_scroll_top)
        {
            clearInterval(scrollInterval);
        }

    }, speed_ms);
}

You can change variables action_count, speed_ms to configure scrolling animation on your taste.

I had that problem too...turns out my credit card info on file needed updated to my new expiration date.

These instructions came from troubleshooting on my phone.

On a computer (not tablet or phone) sign into your Google Wallet, click Payment Methods then edit to edit info. Hope it works for you too!

Change your foreach to something like this, You are not assigning data back to your return variable $data after performing operation on that.

foreach($data as $key => $value)
{
  $data[$key]['transaction_date'] = date('d/m/Y',$value['transaction_date']);
}

You can use bitmap for better performance with large array.

    java.util.Arrays.fill(bitmap, false);

    for (int item : zipcodeList)
        if (!bitmap[item]) bitmap[item] = true;
        else break;

UPDATE: This is a very negligent answer of mine back in the day, keeping it here just for reference. You should refer to andersoj's excellent answer.

IIRC ...

setSize sets the size of the component.

setPreferredSize sets the preferred size. The Layoutmanager will try to arrange that much space for your component.

It depends on whether you're using a layout manager or not ...

May be you can just use the split method to eliminate the '/myapp' for example:

string[] uris=request.getRequestURI().split("/");
string uri="/"+uri[1]+"/"+uris[2];

Note: Test your case, see comments.

Here's a sample which is more efficient on long strings with many small replacements.

source = "Here is foo, it does moo!"

replacements = {
    'is': 'was', # replace 'is' with 'was'
    'does': 'did',
    '!': '?'
}

def replace(source, replacements):
    finder = re.compile("|".join(re.escape(k) for k in replacements.keys())) # matches every string we want replaced
    result = []
    pos = 0
    while True:
        match = finder.search(source, pos)
        if match:
            # cut off the part up until match
            result.append(source[pos : match.start()])
            # cut off the matched part and replace it in place
            result.append(replacements[source[match.start() : match.end()]])
            pos = match.end()
        else:
            # the rest after the last match
            result.append(source[pos:])
            break
    return "".join(result)

print replace(source, replacements)

The point is in avoiding many concatenations of long strings. We chop the source string to fragments, replacing some of the fragments as we form the list, and then join the whole thing back into a string.

MacOS Sierra users can find their auto-generated vanity URL by going to System Preferences > Sharing and checking beneath the Computer Name text input. To access it, enter this URL, plus your port number (e.g. your-name.local:8000), on your iPhone over the same Wi-Fi connection as your computer.

If you don't use a passphrase, then the private key is not encrypted with any symmetric cipher - it is output completely unprotected.

You can generate a keypair, supplying the password on the command-line using an invocation like (in this case, the password is foobar):

openssl genrsa -aes128 -passout pass:foobar 3072

However, note that this passphrase could be grabbed by any other process running on the machine at the time, since command-line arguments are generally visible to all processes.

A better alternative is to write the passphrase into a temporary file that is protected with file permissions, and specify that:

openssl genrsa -aes128 -passout file:passphrase.txt 3072

Or supply the passphrase on standard input:

openssl genrsa -aes128 -passout stdin 3072

You can also used a named pipe with the file: option, or a file descriptor.

To then obtain the matching public key, you need to use openssl rsa, supplying the same passphrase with the -passin parameter as was used to encrypt the private key:

openssl rsa -passin file:passphrase.txt -pubout

(This expects the encrypted private key on standard input - you can instead read it from a file using -in <file>).

Example of creating a 3072-bit private and public key pair in files, with the private key pair encrypted with password foobar:

openssl genrsa -aes128 -passout pass:foobar -out privkey.pem 3072
openssl rsa -in privkey.pem -passin pass:foobar -pubout -out privkey.pub

Just like Namespace of C# codes.

Looping through all the files in the folder is relatively easy:

files = dir('*.csv');
for file = files'
    csv = load(file.name);
    % Do some stuff
end

A cleaner alternative of putting your config file into a subfolder of src/main/resources would be to enhance your classpath locations. This is extremely easy to do with Maven.

For instance, place your property file in a new folder src/main/config, and add the following to your pom:

 <build>
    <resources>
        <resource>
            <directory>src/main/config</directory>
        </resource>
    </resources>
 </build>

From now, every files files under src/main/config is considered as part of your classpath (note that you can exclude some of them from the final jar if needed: just add in the build section:

    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-jar-plugin</artifactId>
            <configuration>
                <excludes>
                    <exclude>my-config.properties</exclude>
                </excludes>
            </configuration>
        </plugin>
    </plugins>

so that my-config.properties can be found in your classpath when you run your app from your IDE, but will remain external from your jar in your final distribution).

To change password using Linux command line, use:

sudo -u <user_name> psql -c "ALTER USER <user_name> PASSWORD '<new_password>';"

fs.readFile takes a call back which calls response.send as you have shown - good. If you simply replace that with fs.readFileSync, you need to be aware it does not take a callback so your callback which calls response.send will never get called and therefore the response will never end and it will timeout.

You need to show your readFileSync code if you're not simply replacing readFile with readFileSync.

Also, just so you're aware, you should never call readFileSync in a node express/webserver since it will tie up the single thread loop while I/O is performed. You want the node loop to process other requests until the I/O completes and your callback handling code can run.

if(($("#checkboxid1").is(":checked")) || ($("#checkboxid2").is(":checked"))
            || ($("#checkboxid3").is(":checked"))) {
 //Your Code here
}

You can use this code to verify that checkbox is checked at least one.

Thanks!!

Remove the first / in the path. Also you don't need type="text/javascript" anymore in HTML5.

Here is some code I wrote to flatten an object I was working with. It creates a new class that takes every nested field and brings it into the first layer. You could modify it to unflatten by remembering the original placement of the keys. It also assumes the keys are unique even across nested objects. Hope it helps.

class JSONFlattener {
    ojson = {}
    flattenedjson = {}

    constructor(original_json) {
        this.ojson = original_json
        this.flattenedjson = {}
        this.flatten()
    }

    flatten() {
        Object.keys(this.ojson).forEach(function(key){
            if (this.ojson[key] == null) {

            } else if (this.ojson[key].constructor == ({}).constructor) {
                this.combine(new JSONFlattener(this.ojson[key]).returnJSON())
            } else {
                this.flattenedjson[key] = this.ojson[key]
            }
        }, this)        
    }

    combine(new_json) {
        //assumes new_json is a flat array
        Object.keys(new_json).forEach(function(key){
            if (!this.flattenedjson.hasOwnProperty(key)) {
                this.flattenedjson[key] = new_json[key]
            } else {
                console.log(key+" is a duplicate key")
            }
        }, this)
    }

    returnJSON() {
        return this.flattenedjson
    }
}

console.log(new JSONFlattener(dad_dictionary).returnJSON())

As an example, it converts

nested_json = {
    "a": {
        "b": {
            "c": {
                "d": {
                    "a": 0
                }
            }
        }
    },
    "z": {
        "b":1
    },
    "d": {
        "c": {
            "c": 2
        }
    }
}

into

{ a: 0, b: 1, c: 2 }

Because the dataset property wasn't supported by Internet Explorer until version 11, you may want to use getAttribute() instead:

document.getElementById("the-span").addEventListener("click", function(){
  console.log(this.getAttribute('data-type'));
});

You need to escape the " so that PHP doesn't recognise them as part of your PHP code. You do this by using the \ escape character.

So, your code would look like this:

echo
    "<div>
        <h3><a href=\"#\">First</a></h3>
        <div>Lorem ipsum dolor sit amet.</div>
    </div>
    <div>"

Grokking lookaround rapidly.
How to distinguish lookahead and lookbehind? Take 2 minutes tour with me:

(?=) - positive lookahead
(?<=) - positive lookbehind

Suppose

    A  B  C #in a line

Now, we ask B, Where are you?
B has two solutions to declare it location:

One, B has A ahead and has C bebind
Two, B is ahead(lookahead) of C and behind (lookhehind) A.

As we can see, the behind and ahead are opposite in the two solutions.
Regex is solution Two.

Here is what you can do if you want to add a column of numbers in Excel. ( I am using Excel 2010 but should not make a difference.)

Example: Lets say you want to add the cells in Column B form B10 to B100 & want the answer to be in cell X or be Variable X ( X can be any cell or any variable you create such as Dim X as integer, etc). Here is the code:

Range("B5") = "=SUM(B10:B100)"

or

X = "=SUM(B10:B100)

There are no quotation marks inside the parentheses in "=Sum(B10:B100) but there are quotation marks inside the parentheses in Range("B5"). Also there is a space between the equals sign and the quotation to the right of it.

It will not matter if some cells are empty, it will simply see them as containing zeros!

This should do it for you!

@Ignatius most excellent answer, updated to work with v2.0.7 of MarkerClustererPlus.

1. Add a prototype click method in the MarkerClusterer class, like so - we will override this later in the map initialize() function:

   // BEGIN MODIFICATION (around line 715)
   MarkerClusterer.prototype.onClick = function() { 
       return true; 
   };
   // END MODIFICATION
   

2. In the ClusterIcon class, add the following code AFTER the click/clusterclick trigger:

   // EXISTING CODE (around line 143)
   google.maps.event.trigger(mc, "click", cClusterIcon.cluster_);
   google.maps.event.trigger(mc, "clusterclick", cClusterIcon.cluster_); // deprecated name
   
   // BEGIN MODIFICATION
   var zoom = mc.getMap().getZoom();
   // Trying to pull this dynamically made the more zoomed in clusters not render
   // when then kind of made this useless. -NNC @ BNB
   // var maxZoom = mc.getMaxZoom();
   var maxZoom = 15;
   // if we have reached the maxZoom and there is more than 1 marker in this cluster
   // use our onClick method to popup a list of options
   if (zoom >= maxZoom && cClusterIcon.cluster_.markers_.length > 1) {
       return mc.onClick(cClusterIcon);
   }
   // END MODIFICATION
   

3. Then, in your initialize() function where you initialize the map and declare your MarkerClusterer object:

   markerCluster = new MarkerClusterer(map, markers);
   // onClick OVERRIDE
   markerCluster.onClick = function(clickedClusterIcon) { 
     return multiChoice(clickedClusterIcon.cluster_); 
   }
   

   Where multiChoice() is YOUR (yet to be written) function to popup an InfoWindow with a list of options to select from. Note that the markerClusterer object is passed to your function, because you will need this to determine how many markers there are in that cluster. For example:

   function multiChoice(clickedCluster) {
     if (clickedCluster.getMarkers().length > 1)
     {
       // var markers = clickedCluster.getMarkers();
       // do something creative!
       return false;
     }
     return true;
   };
   

In my case i had some problem with opacity transition so this one fix it:

#dropdown {
    transition:.6s opacity;
}
#dropdown.ns {
    opacity:0;
    transition:.6s all;
}
#dropdown.fade {
    opacity:1;
}

Mouse Enter

$('#dropdown').removeClass('ns').addClass('fade');

Mouse Leave

$('#dropdown').addClass('ns').removeClass('fade');

You can use window.location

window.location="/newpage.php";

Or you can just make the form that the search button is in have a action of the page you want.

Click on the Window tab in Eclipse, go to Preferences and when that window comes up, go to Java ? Installed JREs ? Execution Environment and choose JavaSE-1.5. You then have to go to Compiler and set the Compiler compliance level.

subprocess.check_output() returns a bytestring.

In Python 3, there's no implicit conversion between unicode (str) objects and bytes objects. If you know the encoding of the output, you can .decode() it to get a string, or you can turn the \n you want to add to bytes with "\n".encode('ascii')

UniversalIndentGUI did the job for me, once configured properly as described above.

TextFX would not install and run correctly on an old PC I have running Windows XP. There are instructions above for manual installation of various DLL files, but I'd rather avoid any manual installation.

UniversalIndentGUI formatted some lines like this:

        <ClockStatus>1
        </ClockStatus>

And I would have preferred:

        <ClockStatus>1</ClockStatus>

But the output is still much better than one long line!

To toast in Android

Toast.makeText(MainActivity.this, "YOUR MESSAGE", LENGTH_SHORT).show();

or

Toast.makeText(MainActivity.this, "YOUR MESSAGE", LENGTH_LONG).show();

( LENGTH_SHORT and LENGTH_LONG are acting as boolean flags - which means you cant sent toast timer to miliseconds, but you need to use either of those 2 options )

The same as David's, but without attr()

$('<input>', {
    type: 'hidden',
    id: 'foo',
    name: 'foo',
    value: 'bar'
}).appendTo('form');

Please try:

str1.contains(str2)

You could use jquery to get hold of the html element that you want to load the value with.

Say for instance if your page looks something like this,

<div id="FirstDiv">
  <div id="SecondDiv">
     ...
  </div>
 </div>

And if your javascript (I hope) looks something as simple as this,

function somefunction(){
  var somevalue = "Data to be inserted";
  $("#SecondDiv").text(somevalue);
}

I hope this is what you were looking for.

>> /dev/null redirects standard output (stdout) to /dev/null, which discards it.

(The >> seems sort of superfluous, since >> means append while > means truncate and write, and either appending to or writing to /dev/null has the same net effect. I usually just use > for that reason.)

2>&1 redirects standard error (2) to standard output (1), which then discards it as well since standard output has already been redirected.

It has a -force parameter.????

As defined in App_start.BundleConfig, it's just calling

bundles.Add(new StyleBundle("~/Content/css").Include("~/Content/site.css"));

Nothing happens even if you remove that section.

EDIT: This is quite old, and ugly, don't do this. You should use callbacks: https://stackoverflow.com/a/5316755/591257

EDIT 2: See the fetch API

Had same problem, solved it this way, using a global var. Not sure if it's the best but surely works. On error you get an empty string (myVar = ''), so you can handle that as needed.

var myVar = '';
function isSession(selector) {
  $.ajax({
    'type': 'POST',
    'url': '/order.html',
    'data': {
      'issession': 1,
      'selector': selector
    },
    'dataType': 'html',
    'success': function(data) {
      myVar = data;
    },
    'error': function() {
      alert('Error occured');
    }
  });
  return myVar;
}

You could use apply() and do something like this

df['que'] = df.apply(lambda x : x['one'] if x['one'] >= x['two'] and x['one'] <= x['three'] else "", axis=1)

or if you prefer not to use a lambda

def que(x):
    if x['one'] >= x['two'] and x['one'] <= x['three']:
        return x['one']
    return ''
df['que'] = df.apply(que, axis=1)

you're getting that poor transition because you're adjusting the position of the element every time the document is scrolled. What you want is to use fixed positioning. I tried that fixed center plugin listed above and that seems to do solve the problem nicely. Fixed positioning allows you to center an element once, and the CSS property will take care of maintaining that position for you every time you scroll.

On ipython or jupyter notebook, you can use all the above mentioned ways, but i go with

my_func?

or

?my_func

for quick summary of both method signature and docstring.

I avoid using

my_func??

(as commented by @rohan) for docstring and use it only to check the source code

I discovered that this behaviour only occurs after running a particular script, similar to the one in the question. I have no idea why it occurs.

It works (refreshes the graphs) if I put

plt.clf()
plt.cla()
plt.close()

after every plt.show()

That's my solution

<div class="main" style="width: 100%;">
    <div class="container">
        <div class="sizing"></div>
        <div class="content"></div>
    </div>
</div>

.main {
    width: 100%;
}
.container {
    width: 30%;
    float: right;
    position: relative;
}
.sizing {
    width: 100%;
    padding-bottom: 50%;
    visibility: hidden;
}
.content {
    width: 100%;
    height: 100%;
    background-color: red;
    position: absolute;
    margin-top: -50%;
}

Nobody has mentioned GetPerformanceInfo yet. PInvoke signatures are available.

This function makes the following system-wide information available:

• CommitTotal
• CommitLimit
• CommitPeak
• PhysicalTotal
• PhysicalAvailable
• SystemCache
• KernelTotal
• KernelPaged
• KernelNonpaged
• PageSize
• HandleCount
• ProcessCount
• ThreadCount

PhysicalTotal is what the OP is looking for, although the value is the number of pages, so to convert to bytes, multiply by the PageSize value returned.

Here is the complete solution as a function:

function varDumpToString ($var)
{
    ob_start();
    var_dump($var);
    return ob_get_clean();
}

First things is this is only for advanced developers persons Who all are now beginner to php dont use this function if you are using the huge project in core php use this function

function displayAllRecords($serverName, $userName, $password, $databaseName,$sqlQuery='')
{
    $databaseConnectionQuery =  mysqli_connect($serverName, $userName, $password, $databaseName);
    if($databaseConnectionQuery === false)
    {
        die("ERROR: Could not connect. " . mysqli_connect_error());
        return false;
    }

    $resultQuery = mysqli_query($databaseConnectionQuery,$sqlQuery);
    $fetchFields = mysqli_fetch_fields($resultQuery);
    $fetchValues = mysqli_fetch_fields($resultQuery);

    if (mysqli_num_rows($resultQuery) > 0) 
    {           

        echo "<table class='table'>";
        echo "<tr>";
        foreach ($fetchFields as $fetchedField)
         {          
            echo "<td>";
            echo "<b>" . $fetchedField->name . "<b></a>";
            echo "</td>";
        }       
        echo "</tr>";
        while($totalRows = mysqli_fetch_array($resultQuery)) 
        {           
            echo "<tr>";                                
            for($eachRecord = 0; $eachRecord < count($fetchValues);$eachRecord++)
            {           
                echo "<td>";
                echo $totalRows[$eachRecord];
                echo "</td>";               
            }
            echo "<td><a href=''><button>Edit</button></a></td>";
            echo "<td><a href=''><button>Delete</button></a></td>";
            echo "</tr>";           
        } 
        echo "</table>";        

    } 
    else
    {
      echo "No Records Found in";
    }
}

All set now Pass the arguments as For Example

$queryStatment = "SELECT * From USERS "; $testing = displayAllRecords('localhost','root','root@123','email',$queryStatment); echo $testing;

Here

localhost indicates Name of the host,

root indicates the username for database

root@123 indicates the password for the database

$queryStatment for generating Query

hope it helps

I'm not sure if there is but if there was such a property it wouldn't be considered reliable. A WebException can be fired for reasons other than HTTP error codes including simple networking errors. Those have no such matching http error code.

Can you give us a bit more info on what you're trying to accomplish with that code. There may be a better way to get the information you need.

No. Any valid string is a valid key. It can even have " as long as you escape it:

{"The \"meaning\" of life":42}

There is perhaps a chance you'll encounter difficulties loading such values into some languages, which try to associate keys with object field names. I don't know of any such cases, however.

In order to prove that a problem L is NP-complete, we need to do the following steps:

1. Prove your problem L belongs to NP (that is that given a solution you can verify it in polynomial time)
2. Select a known NP-complete problem L'
3. Describe an algorithm f that transforms L' into L
4. Prove that your algorithm is correct (formally: x ? L' if and only if f(x) ? L )
5. Prove that algo f runs in polynomial time

Here's a simpler solution: install python-chromedrive package, import it in your script, and it's done.

Step by step:
1. pip install chromedriver-binary
2. import the package

from selenium import webdriver
import chromedriver_binary  # Adds chromedriver binary to path

driver = webdriver.Chrome()
driver.get("http://www.python.org")

Reference: https://pypi.org/project/chromedriver-binary/

Another option is to insert a minipage in each cell where text wrapping is desired, e.g.:

\begin{table}[H]
\begin{tabular}{l}
\begin{minipage}[t]{0.8\columnwidth}%
a very long line a very long line a very long line a very long line
a very long line a very long line a very long line a very long line
a very long line a very long line a very long line %
\end{minipage}\tabularnewline
\end{tabular}
\end{table}

Apparently, you can just inject IEnumerable of your service interface! And then find the instance that you want using LINQ.

My example is for the AWS SNS service but you can do the same for any injected service really.

Startup

foreach (string snsRegion in Configuration["SNSRegions"].Split(',', StringSplitOptions.RemoveEmptyEntries))
{
    services.AddAWSService<IAmazonSimpleNotificationService>(
        string.IsNullOrEmpty(snsRegion) ? null :
        new AWSOptions()
        {
            Region = RegionEndpoint.GetBySystemName(snsRegion)
        }
    );
}

services.AddSingleton<ISNSFactory, SNSFactory>();

services.Configure<SNSConfig>(Configuration);

SNSConfig

public class SNSConfig
{
    public string SNSDefaultRegion { get; set; }
    public string SNSSMSRegion { get; set; }
}

appsettings.json

  "SNSRegions": "ap-south-1,us-west-2",
  "SNSDefaultRegion": "ap-south-1",
  "SNSSMSRegion": "us-west-2",

SNS Factory

public class SNSFactory : ISNSFactory
{
    private readonly SNSConfig _snsConfig;
    private readonly IEnumerable<IAmazonSimpleNotificationService> _snsServices;

    public SNSFactory(
        IOptions<SNSConfig> snsConfig,
        IEnumerable<IAmazonSimpleNotificationService> snsServices
        )
    {
        _snsConfig = snsConfig.Value;
        _snsServices = snsServices;
    }

    public IAmazonSimpleNotificationService ForDefault()
    {
        return GetSNS(_snsConfig.SNSDefaultRegion);
    }

    public IAmazonSimpleNotificationService ForSMS()
    {
        return GetSNS(_snsConfig.SNSSMSRegion);
    }

    private IAmazonSimpleNotificationService GetSNS(string region)
    {
        return GetSNS(RegionEndpoint.GetBySystemName(region));
    }

    private IAmazonSimpleNotificationService GetSNS(RegionEndpoint region)
    {
        IAmazonSimpleNotificationService service = _snsServices.FirstOrDefault(sns => sns.Config.RegionEndpoint == region);

        if (service == null)
        {
            throw new Exception($"No SNS service registered for region: {region}");
        }

        return service;
    }
}

public interface ISNSFactory
{
    IAmazonSimpleNotificationService ForDefault();

    IAmazonSimpleNotificationService ForSMS();
}

Now you can get the SNS service for the region that you want in your custom service or controller

public class SmsSender : ISmsSender
{
    private readonly IAmazonSimpleNotificationService _sns;

    public SmsSender(ISNSFactory snsFactory)
    {
        _sns = snsFactory.ForSMS();
    }

    .......
 }

public class DeviceController : Controller
{
    private readonly IAmazonSimpleNotificationService _sns;

    public DeviceController(ISNSFactory snsFactory)
    {
        _sns = snsFactory.ForDefault();
    }

     .........
}

Problem was my package name. It MUST be "com.outbottle" (then config/controllers/model/etc) for it to work. As you can see above, I used Maven (for the first time), Spring, 1.8 JDK and nearly had a stroke debugging this issue. All running on Glassfish (Tomcat is ok too for the above pom config). That said, I'm all happy with myself now and know Maven and Spring much better for the next step of my Spring learning curve. Hoping this helps you also!

As shown earlier, flexbox is the easiest. eg.

#main{ display: flex; align-items:center;}

this will align all child elements to the center within the parent element.

An extension to what GenericTypeTea says - Here is a concrete example:

<form onsubmit="return false">

The above form will not submit, whereas...

<form onsubmit="false">

...does nothing, i.e. the form will submit.

Without the return, onsubmit doesn't receive a value and the event is executed just like without any handler at all.

Check out commons math from apache. There is quite a lot there.

I don't believe AJAX can handle file uploads but this can be achieved with libraries that leverage flash. Another advantage of the flash implementation is the ability to do multiple files at once (like gmail).

SWFUpload is a good start : http://www.swfupload.org/documentation

jQuery and some of the other libraries have plugins that leverage SWFUpload. On my last project we used SWFUpload and Java without a problem.

Also helpful and worth looking into is Apache's FileUpload : http://commons.apache.org/fileupload/index.html

Have you tried:

ifconfig 10:35978f0 down

As the physical interface is 10 and the virtual aspect is after the colon :.

You can use plain javascript, this will call your_func once, after 5 seconds:

setTimeout(function() { your_func(); }, 5000);

If your function has no parameters and no explicit receiver you can call directly setTimeout(func, 5000)

There is also a plugin I've used once. It has oneTime and everyTime methods.

I change upload method with images[] according to @Denmark.

    private function upload_files($path, $title, $files)
    {
        $config = array(
            'upload_path'   => $path,
            'allowed_types' => 'jpg|gif|png',
            'overwrite'     => 1,                       
        );

        $this->load->library('upload', $config);

        $images = array();

        foreach ($files['name'] as $key => $image) {
            $_FILES['images[]']['name']= $files['name'][$key];
            $_FILES['images[]']['type']= $files['type'][$key];
            $_FILES['images[]']['tmp_name']= $files['tmp_name'][$key];
            $_FILES['images[]']['error']= $files['error'][$key];
            $_FILES['images[]']['size']= $files['size'][$key];

            $fileName = $title .'_'. $image;

            $images[] = $fileName;

            $config['file_name'] = $fileName;

            $this->upload->initialize($config);

            if ($this->upload->do_upload('images[]')) {
                $this->upload->data();
            } else {
                return false;
            }
        }

        return $images;
    }

This can be done with PIL. First, install it, then you can take a full screenshot like this:

import PIL.ImageGrab

im = PIL.ImageGrab.grab()
im.show()

Simply put, Git is a version control system that lets you manage and keep track of your source code history. GitHub is a cloud-based hosting service that lets you manage Git repositories. If you have open-source projects that use Git, then GitHub is designed to help you better manage them.

Also struggled, but got it right typing

git add -f ./JS/*

where JS was my folder name which contain sub folders and files

At the time when this question was asked there wasn't another function in Pandas to test equality, but it has been added a while ago: pandas.equals

You use it like this:

df1.equals(df2)

Some differenes to == are:

• You don't get the error described in the question
• It returns a simple boolean.
• NaN values in the same location are considered equal
• 2 DataFrames need to have the same dtype to be considered equal, see this stackoverflow question

Try:

List<String> textFiles(String directory) {
  List<String> textFiles = new ArrayList<String>();
  File dir = new File(directory);
  for (File file : dir.listFiles()) {
    if (file.getName().endsWith((".txt"))) {
      textFiles.add(file.getName());
    }
  }
  return textFiles;
}

You want to do a case insensitive search in which case:

    if (file.getName().toLowerCase().endsWith((".txt"))) {

If you want to recursively search for through a directory tree for text files, you should be able to adapt the above as either a recursive function or an iterative function using a stack.

looks like you have maven project and so resources are in classpath by

go for

getClass().getResource("classpath:storedProcedures.sql")

def to_infinity():
    index = 0
    while True:
        yield index
        index += 1

for i in to_infinity():
    if i > 10:
        break

I think using NOW() function is incorrect for getting time difference. Because by NOW() function every time your are calculating the past 24 hours. You must use CURDATE() instead.

    function your_function($time, $your_date) {
    if ($time == 'today') {
        $timeSQL = ' Date($your_date)= CURDATE()';
    }
    if ($time == 'week') {
        $timeSQL = ' YEARWEEK($your_date)= YEARWEEK(CURDATE())';
    }
    if ($time == 'month') {
        $timeSQL = ' Year($your_date)=Year(CURDATE()) AND Month(`your_date`)= Month(CURDATE())';
    }

    $Sql = "SELECT * FROM jokes WHERE ".$timeSQL
    return $Result = $this->db->query($Sql)->result_array();
}

This is the simple one to perform substring in Go

package main

import "fmt"

var p = fmt.Println

func main() {

  value := "address;bar"

  // Take substring from index 2 to length of string
  substring := value[2:len(value)]
  p(substring)

}

Edit: now there is yet an easier way to do this - when creating your group, just mention the full bot name (eg. @UniversalAgent1Bot) and it will list it as you type. Then you can just tap on it to add it.

Old answer:

1. Create a new group from the menu. Don't add any bots yet
2. Find the bot (for instance you can go to Contacts and search for it)
3. Tap to open
4. Tap the bot name on the top bar. Your page becomes like this:
5. Now, tap the triple ... and you will get the Add to Group button:
6. Now select your group and add the bot - and confirm the addition

I found a much easier way, it doesn't even use SP.UserProfiles.js. I don't know if it applies to each one's particular case, but definitely worth sharing.

//assume we have a client context called context.
var web = context.get_web();
var user = web.get_currentUser(); //must load this to access info.
context.load(user);
context.executeQueryAsync(function(){
    alert("User is: " + user.get_title()); //there is also id, email, so this is pretty useful.
}, function(){alert(":(");});

Anyways, thanks to your answers, I got to mingle a bit with UserProfiles, even though it is not really necessary for my case.

Facade hides the complexities of the system and provides an interface to the client from where the client can access the system.

public class Inventory {
public String checkInventory(String OrderId) {
    return "Inventory checked";

public void placeOrder(String orderId) {
    String step1 = inventry.checkInventory(orderId);
    String step2 = pymt.deductPayment(orderId);
    System.out
            .println("Following steps completed:" + step1
                    + " & " + step2);
   }
}

         System.out.println("Order processing completed");
       }
  }

You can use either SEQUENCE or TRIGGER to increment automatically the value of a given column in your database table however the use of TRIGGERS would be more appropriate. See the following documentation of Oracle that contains major clauses used with triggers with suitable examples.

Use the CREATE TRIGGER statement to create and enable a database trigger, which is:

• A stored PL/SQL block associated with a table, a schema, or the database or

• An anonymous PL/SQL block or a call to a procedure implemented in PL/SQL or Java

Oracle Database automatically executes a trigger when specified conditions occur. See.

Following is a simple TRIGGER just as an example for you that inserts the primary key value in a specified table based on the maximum value of that column. You can modify the schema name, table name etc and use it. Just give it a try.

/*Create a database trigger that generates automatically primary key values on the CITY table using the max function.*/

CREATE OR REPLACE TRIGGER PROJECT.PK_MAX_TRIGGER_CITY
BEFORE INSERT ON PROJECT.CITY
FOR EACH ROW
DECLARE 
    CNT NUMBER;
    PKV CITY.CITY_ID%TYPE;
    NO NUMBER;
BEGIN
    SELECT COUNT(*)INTO CNT FROM CITY;

    IF CNT=0 THEN
        PKV:='CT0001';
    ELSE
        SELECT 'CT'||LPAD(MAX(TO_NUMBER(SUBSTR(CITY_ID,3,LENGTH(CITY_ID)))+1),4,'0') INTO PKV
        FROM CITY;
    END IF; 
    :NEW.CITY_ID:=PKV;
END;

Would automatically generates values such as CT0001, CT0002, CT0002 and so on and inserts into the given column of the specified table.

If you have a _Layout.cshtml view like this

<html>
    <body>
        @RenderBody()
        @RenderSection("scripts", required: false)
    </body>
</html>

then you can have an index.cshtml content view like this

@section scripts {
     <script type="text/javascript">alert('hello');</script>
}

the required indicates whether or not the view using the layout page must have a scripts section

Remove this from #info:

    margin-left:auto;

Add this for your header:

#info p {
    text-align: center;
}

Do you need the fixed width etc.? I removed the in my opinion not necessary stuff and centered the header with text-align.

Sample
http://jsfiddle.net/Vc8CB/

an inline solution combines Groot and Ivaylo suggestions in the format below:

onchange="(function(el){el.value=parseFloat(el.value).toFixed(2);})(this)"

I always use the isoformat() function for this.

from datetime import date    
today = date.today().isoformat()
print(today) # '2018-12-05'

Note that this also works on datetime objects if you need the time in standard format as well.

from datetime import datetime
now = datetime.today().isoformat()
print(now) # '2018-12-05T11:15:55.126382'

I think you want to handle most of the work with lists then use the result as a matrix. Maybe this is a way ;

ur_list = []
for col in columns:
    ur_list.append(list(col))

mat = np.matrix(ur_list)

I think the best way is to use file.length == 0.

It is sometimes possible that the first line is empty.

If you want to load csv as a dataframe then you can do the following:

from pyspark.sql import SQLContext
sqlContext = SQLContext(sc)

df = sqlContext.read.format('com.databricks.spark.csv') \
    .options(header='true', inferschema='true') \
    .load('sampleFile.csv') # this is your csv file

It worked fine for me.

I recommend using the download attribute for download instead of jQuery:

<a href="your_link" download> file_name </a>

This will download your file, without opening it.

As mrjrdnthms points out in his comment on the accepted answer, this no longer works on Chrome (it always fires the mousemove), I've adapted Gustavo's answer (since I'm using jQuery) to address the Chrome behavior.

var currentPos = [];

$(document).on('mousedown', function (evt) {

   currentPos = [evt.pageX, evt.pageY]

  $(document).on('mousemove', function handler(evt) {

    currentPos=[evt.pageX, evt.pageY];
    $(document).off('mousemove', handler);

  });

  $(document).on('mouseup', function handler(evt) {

    if([evt.pageX, evt.pageY].equals(currentPos))
      console.log("Click")
    else
      console.log("Drag")

    $(document).off('mouseup', handler);

  });

});

The Array.prototype.equals function comes from this answer

If I had to guess, I'd say you installed the PPA 7.1.8 as CLI only (php7-cli). You're getting your version info from that, but your libapache2-mod-php package is still 14.04 main which is 5.6. Check your phpinfo in your browser to confirm the version. You might also consider migrating to Ubuntu 16.04 to get PHP 7.0 in main.

The AlexFTPS library used in the question seems to be dead (was not updated since 2011).

With no external libraries

You can try to implement this without any external library. But unfortunately, neither the .NET Framework nor PowerShell have any explicit support for downloading all files in a directory (let only recursive file downloads).

You have to implement that yourself:

• List the remote directory
• Iterate the entries, downloading files (and optionally recursing into subdirectories - listing them again, etc.)

Tricky part is to identify files from subdirectories. There's no way to do that in a portable way with the .NET framework (FtpWebRequest or WebClient). The .NET framework unfortunately does not support the MLSD command, which is the only portable way to retrieve directory listing with file attributes in FTP protocol. See also Checking if object on FTP server is file or directory.

Your options are:

• If you know that the directory does not contain any subdirectories, use the ListDirectory method (NLST FTP command) and simply download all the "names" as files.
• Do an operation on a file name that is certain to fail for file and succeeds for directories (or vice versa). I.e. you can try to download the "name".
• You may be lucky and in your specific case, you can tell a file from a directory by a file name (i.e. all your files have an extension, while subdirectories do not)
• You use a long directory listing (LIST command = ListDirectoryDetails method) and try to parse a server-specific listing. Many FTP servers use *nix-style listing, where you identify a directory by the d at the very beginning of the entry. But many servers use a different format. The following example uses this approach (assuming the *nix format)

function DownloadFtpDirectory($url, $credentials, $localPath)
{
    $listRequest = [Net.WebRequest]::Create($url)
    $listRequest.Method = [System.Net.WebRequestMethods+Ftp]::ListDirectoryDetails
    $listRequest.Credentials = $credentials

    $lines = New-Object System.Collections.ArrayList

    $listResponse = $listRequest.GetResponse()
    $listStream = $listResponse.GetResponseStream()
    $listReader = New-Object System.IO.StreamReader($listStream)
    while (!$listReader.EndOfStream)
    {
        $line = $listReader.ReadLine()
        $lines.Add($line) | Out-Null
    }
    $listReader.Dispose()
    $listStream.Dispose()
    $listResponse.Dispose()

    foreach ($line in $lines)
    {
        $tokens = $line.Split(" ", 9, [StringSplitOptions]::RemoveEmptyEntries)
        $name = $tokens[8]
        $permissions = $tokens[0]

        $localFilePath = Join-Path $localPath $name
        $fileUrl = ($url + $name)

        if ($permissions[0] -eq 'd')
        {
            if (!(Test-Path $localFilePath -PathType container))
            {
                Write-Host "Creating directory $localFilePath"
                New-Item $localFilePath -Type directory | Out-Null
            }

            DownloadFtpDirectory ($fileUrl + "/") $credentials $localFilePath
        }
        else
        {
            Write-Host "Downloading $fileUrl to $localFilePath"

            $downloadRequest = [Net.WebRequest]::Create($fileUrl)
            $downloadRequest.Method = [System.Net.WebRequestMethods+Ftp]::DownloadFile
            $downloadRequest.Credentials = $credentials

            $downloadResponse = $downloadRequest.GetResponse()
            $sourceStream = $downloadResponse.GetResponseStream()
            $targetStream = [System.IO.File]::Create($localFilePath)
            $buffer = New-Object byte[] 10240
            while (($read = $sourceStream.Read($buffer, 0, $buffer.Length)) -gt 0)
            {
                $targetStream.Write($buffer, 0, $read);
            }
            $targetStream.Dispose()
            $sourceStream.Dispose()
            $downloadResponse.Dispose()
        }
    }
}

Use the function like:

$credentials = New-Object System.Net.NetworkCredential("user", "mypassword") 
$url = "ftp://ftp.example.com/directory/to/download/"
DownloadFtpDirectory $url $credentials "C:\target\directory"

The code is translated from my C# example in C# Download all files and subdirectories through FTP.

Using 3rd party library

If you want to avoid troubles with parsing the server-specific directory listing formats, use a 3rd party library that supports the MLSD command and/or parsing various LIST listing formats. And ideally with a support for downloading all files from a directory or even recursive downloads.

For example with WinSCP .NET assembly you can download whole directory with a single call to Session.GetFiles:

# Load WinSCP .NET assembly
Add-Type -Path "WinSCPnet.dll"

# Setup session options
$sessionOptions = New-Object WinSCP.SessionOptions -Property @{
    Protocol = [WinSCP.Protocol]::Ftp
    HostName = "ftp.example.com"
    UserName = "user"
    Password = "mypassword"
}

$session = New-Object WinSCP.Session

try
{
    # Connect
    $session.Open($sessionOptions)

    # Download files
    $session.GetFiles("/directory/to/download/*", "C:\target\directory\*").Check()
}
finally
{
    # Disconnect, clean up
    $session.Dispose()
}    

Internally, WinSCP uses the MLSD command, if supported by the server. If not, it uses the LIST command and supports dozens of different listing formats.

The Session.GetFiles method is recursive by default.

(I'm the author of WinSCP)

There is a space missing between elif and [:

elif[ "$seconds" -gt 0 ]

should be

elif [ "$seconds" -gt 0 ]

As I see this question is getting a lot of views, it is important to indicate that the syntax to follow is:

if [ conditions ]
# ^ ^          ^

meaning that spaces are needed around the brackets. Otherwise, it won't work. This is because [ itself is a command.

The reason why you are not seeing something like elif[: command not found (or similar) is that after seeing if and then, the shell is looking for either elif, else, or fi. However it finds another then (after the mis-formatted elif[). Only after having parsed the statement it would be executed (and an error message like elif[: command not found would be output).

There are five ways to output text to the console:

Dim StdOut : Set StdOut = CreateObject("Scripting.FileSystemObject").GetStandardStream(1)

WScript.Echo "Hello"
WScript.StdOut.Write "Hello"
WScript.StdOut.WriteLine "Hello"
Stdout.WriteLine "Hello"
Stdout.Write "Hello"

WScript.Echo will output to console but only if the script is started using cscript.exe. It will output to message boxes if started using wscript.exe.

WScript.StdOut.Write and WScript.StdOut.WriteLine will always output to console.

StdOut.Write and StdOut.WriteLine will also always output to console. It requires extra object creation but it is about 10% faster than WScript.Echo.

In Qt 4.7, there is the QDateTime::currentMSecsSinceEpoch() static function, which does exactly what you need, without any intermediary steps. Hence I'd recommend that for projects using Qt 4.7 or newer.

You have to copy the bits over a new image with the target resolution, like this:

    using (Bitmap bitmap = (Bitmap)Image.FromFile("file.jpg"))
    {
        using (Bitmap newBitmap = new Bitmap(bitmap))
        {
            newBitmap.SetResolution(300, 300);
            newBitmap.Save("file300.jpg", ImageFormat.Jpeg);
        }
    }

With Eclipse Collections, you can do the following if you have a list of type java.util.List<Integer>:

List<Integer> integers = Lists.mutable.with(1, 2, 3, 4, 5);
int[] ints = LazyIterate.adapt(integers).collectInt(i -> i).toArray();

Assert.assertArrayEquals(new int[]{1, 2, 3, 4, 5}, ints);

If you already have an Eclipse Collections type like MutableList, you can do the following:

MutableList<Integer> integers = Lists.mutable.with(1, 2, 3, 4, 5);
int[] ints = integers.asLazy().collectInt(i -> i).toArray();

Assert.assertArrayEquals(new int[]{1, 2, 3, 4, 5}, ints);

Note: I am a committer for Eclipse Collections

You'd need to add moment.lang(navigator.language) in your script.

And must also add each country locale you want to display in : for example for GB or FR, you need to add that locale format in moment.js library. An example of such format is available in momentjs documentation. If you don't add this format in moment.js then it'd ALWAYS pick up US locale as that's the only one that I currently see.

If you are looking for a difference expressed as a combination of years, months, and days, I would suggest this function:

function interval(date1, date2) {_x000D_
    if (date1 > date2) { // swap_x000D_
        var result = interval(date2, date1);_x000D_
        result.years  = -result.years;_x000D_
        result.months = -result.months;_x000D_
        result.days   = -result.days;_x000D_
        result.hours  = -result.hours;_x000D_
        return result;_x000D_
    }_x000D_
    result = {_x000D_
        years:  date2.getYear()  - date1.getYear(),_x000D_
        months: date2.getMonth() - date1.getMonth(),_x000D_
        days:   date2.getDate()  - date1.getDate(),_x000D_
        hours:  date2.getHours() - date1.getHours()_x000D_
    };_x000D_
    if (result.hours < 0) {_x000D_
        result.days--;_x000D_
        result.hours += 24;_x000D_
    }_x000D_
    if (result.days < 0) {_x000D_
        result.months--;_x000D_
        // days = days left in date1's month, _x000D_
        //   plus days that have passed in date2's month_x000D_
        var copy1 = new Date(date1.getTime());_x000D_
        copy1.setDate(32);_x000D_
        result.days = 32-date1.getDate()-copy1.getDate()+date2.getDate();_x000D_
    }_x000D_
    if (result.months < 0) {_x000D_
        result.years--;_x000D_
        result.months+=12;_x000D_
    }_x000D_
    return result;_x000D_
}_x000D_
_x000D_
// Be aware that the month argument is zero-based (January = 0)_x000D_
var date1 = new Date(2015, 4-1, 6);_x000D_
var date2 = new Date(2015, 5-1, 9);_x000D_
_x000D_
document.write(JSON.stringify(interval(date1, date2)));

This solution will treat leap years (29 February) and month length differences in a way we would naturally do (I think).

So for example, the interval between 28 February 2015 and 28 March 2015 will be considered exactly one month, not 28 days. If both those days are in 2016, the difference will still be exactly one month, not 29 days.

Dates with exactly the same month and day, but different year, will always have a difference of an exact number of years. So the difference between 2015-03-01 and 2016-03-01 will be exactly 1 year, not 1 year and 1 day (because of counting 365 days as 1 year).

Try using the following function:

const stringToRegex = str => {
    // Main regex
    const main = str.match(/\/(.+)\/.*/)[1]
    
    // Regex options
    const options = str.match(/\/.+\/(.*)/)[1]
    
    // Compiled regex
    return new RegExp(main, options)
}

You can use it like so:

"abc".match(stringToRegex("/a/g"))
//=> ["a"]

You are missing <context:annotation-config /> from your spring context so the annotations are not being scanned!

You could follow a solution similar to "How do I force “git pull” to overwrite local files?":

git fetch --all
git reset --hard origin/abranch
git checkout $branch 

That would involve only one fetch.

With Git 2.23+, git checkout is replaced here with git switch (presented here) (still experimental).

git switch -f $branch

(with -f being an alias for --discard-changes, as noted in Jan's answer)

Proceed even if the index or the working tree differs from HEAD.
Both the index and working tree are restored to match the switching target.

JRebel is free. Don't buy it. Select the "free" option (radio button) on the "buy" page. Then select "Social". After you sign up, you will get a fully functional JRebel license key. You can then download JRebel or use the key in your IDEs embedded version. The catch, (yes, there is a catch), you have to allow them to post on your behalf (advertise) once a month on your FB timeline or Twitter account. I gave them my twitter account, no biggie, I never use it and no one I know really uses it. So save $260.

Just in case anyone else ends up here from a web search, and has Grunt already in their dependency list, the answer to this becomes trivial. Here's my solution:

/**
 * Return all the subfolders of this path
 * @param {String} parentFolderPath - valid folder path
 * @param {String} glob ['/*'] - optional glob so you can do recursive if you want
 * @returns {String[]} subfolder paths
 */
getSubfolders = (parentFolderPath, glob = '/*') => {
    return grunt.file.expand({filter: 'isDirectory'}, parentFolderPath + glob);
}

Here is an example of print statement use. They should appear under the messages tab as a previous person indicated.

    Declare @TestVar int = 5;

    print 'this is a test message';
    print @TestVar;
    print 'test-' + Convert(varchar(50), @TestVar);

In JSF 1.2 this was done by <f:setPropertyActionListener> (within the command component). In JSF 2.0 (EL 2.2 to be precise, thanks to BalusC) it's possible to do it like this: action="${filterList.insert(f.id)}

On Servlet 3.0 or newer you could just specify

<web-app ...>
    <error-page>
        <location>/general-error.html</location>
    </error-page>
</web-app>

But as you're still on Servlet 2.5, there's no other way than specifying every common HTTP error individually. You need to figure which HTTP errors the enduser could possibly face. On a barebones webapp with for example the usage of HTTP authentication, having a disabled directory listing, using custom servlets and code which can possibly throw unhandled exceptions or does not have all methods implemented, then you'd like to set it for HTTP errors 401, 403, 500 and 503 respectively.

<error-page>
    <!-- Missing login -->
    <error-code>401</error-code>
    <location>/general-error.html</location>
</error-page>
<error-page>
    <!-- Forbidden directory listing -->
    <error-code>403</error-code>
    <location>/general-error.html</location>
</error-page>
<error-page>
    <!-- Missing resource -->
    <error-code>404</error-code>
    <location>/Error404.html</location>
</error-page>
<error-page>
    <!-- Uncaught exception -->
    <error-code>500</error-code>
    <location>/general-error.html</location>
</error-page>
<error-page>
    <!-- Unsupported servlet method -->
    <error-code>503</error-code>
    <location>/general-error.html</location>
</error-page>

That should cover the most common ones.

You can simply use slash (\) if you have multiple lines for your lambda function

Example:

mx = lambda x, y: x if x > y \
     else y
print(mx(30, 20))

Output: 30

You can do it now by using the CSS property -webkit-user-drag:

#drag_me {_x000D_
  -webkit-user-drag: element;_x000D_
}

<div draggable="true" id="drag_me">_x000D_
  Your draggable content here_x000D_
</div>

This property is only supported by webkit browsers, such as Safari or Chrome, but it is a nice approach to get it working using only CSS.

The HTML5 draggable attribute is only set to ensure dragging works for other browsers.

You can find more information here: http://help.dottoro.com/lcbixvwm.php

if you use .Values while creating the matrix X and Y vectors it will fix the problem.

y=dataset.iloc[:, 4].values

X=dataset.iloc[:, 0:4].values

when you use .Values it creates a Object representation of the created matrix will be returned with the axes removed. Check the below link for more information

https://pandas.pydata.org/pandas-docs/stable/generated/pandas.DataFrame.values.html

I solved this by using this way -

    @RunWith(SpringRunner.class)
    @EnableJpaRepositories(basePackages={"com.path.repositories"})
    @EntityScan(basePackages={"com.model"})
    @TestPropertySource("classpath:application.properties")
    @ContextConfiguration(classes = {ApiTestConfig.class,SaveActionsServiceImpl.class})
    public class SaveCriticalProcedureTest {

        @Autowired
        private SaveActionsService saveActionsService;
        .......
        .......
}

The command within the Sqlite shell to open a database is .open

The syntax is,

sqlite> .open dbasename.db

If it is a new database that you would like to create and open, it is

sqlite> .open --new dbasename.db

If the database is existing in a different folder, the path has to be mentioned like this:

sqlite> .open D:/MainFolder/SubFolder/...database.db

In Windows Command shell, you should use '\' to represent a directory, but in SQLite directories are represented by '/'. If you still prefer to use the Windows notation, you should use an escape sequence for every '\'

In Oracle 12c, you can now specify the CURRVAL and NEXTVAL sequence pseudocolumns as default values for a column. Alternatively, you can use Identity columns; see:

• reference doc
• articles: Enhancements in Oracle DB 12cR1 (12.1): Default Values for Table Columns and Identity Columns in 12.1

E.g.,

CREATE SEQUENCE t1_seq;
CREATE TABLE t1 (
  id          NUMBER DEFAULT t1_seq.NEXTVAL,
  description VARCHAR2(30)
);

You could use underscore.js and the each function:

_.each({key1: "value1", key2: "value2"}, function(value) {
  console.log(value);
});

These two procedures let me reset the sequence and reset the sequence based on data in a table (apologies for the coding conventions used by this client):

CREATE OR REPLACE PROCEDURE SET_SEQ_TO(p_name IN VARCHAR2, p_val IN NUMBER)
AS
   l_num   NUMBER;
BEGIN
   EXECUTE IMMEDIATE 'select ' || p_name || '.nextval from dual' INTO l_num;

   -- Added check for 0 to avoid "ORA-04002: INCREMENT must be a non-zero integer"
   IF (p_val - l_num - 1) != 0
   THEN
      EXECUTE IMMEDIATE 'alter sequence ' || p_name || ' increment by ' || (p_val - l_num - 1) || ' minvalue 0';
   END IF;

   EXECUTE IMMEDIATE 'select ' || p_name || '.nextval from dual' INTO l_num;

   EXECUTE IMMEDIATE 'alter sequence ' || p_name || ' increment by 1 ';

   DBMS_OUTPUT.put_line('Sequence ' || p_name || ' is now at ' || p_val);
END;

CREATE OR REPLACE PROCEDURE SET_SEQ_TO_DATA(seq_name IN VARCHAR2, table_name IN VARCHAR2, col_name IN VARCHAR2)
AS
   nextnum   NUMBER;
BEGIN
   EXECUTE IMMEDIATE 'SELECT MAX(' || col_name || ') + 1 AS n FROM ' || table_name INTO nextnum;

   SET_SEQ_TO(seq_name, nextnum);
END;

Declarations of public functions go in header files, yes, but definitions are absolutely valid in headers as well! You may declare the definition as static (only 1 copy allowed for the entire program) if you are defining things in a header for utility functions that you don't want to have to define again in each c file. I.E. defining an enum and a static function to translate the enum to a string. Then you won't have to rewrite the enum to string translator for each .c file that includes the header. :)

You can use inner divs to set the margin.

<div style="display: table-cell;">
   <div style="margin:5px;background-color: red;">1</div>
</div>
<div style="display: table-cell; ">
  <div style="margin:5px;background-color: green;">1</div>
</div>

JS Fiddle

Iterate through the entrySet() like so:

public static void printMap(Map mp) {
    Iterator it = mp.entrySet().iterator();
    while (it.hasNext()) {
        Map.Entry pair = (Map.Entry)it.next();
        System.out.println(pair.getKey() + " = " + pair.getValue());
        it.remove(); // avoids a ConcurrentModificationException
    }
}

From Python 3.3 on, there is the official Python launcher for Windows (http://www.python.org/dev/peps/pep-0397/). Now, you can use the #!pythonX to determine the wanted version of the interpreter also on Windows. See more details in my another comment or read the PEP 397.

Summary: The py script.py launches the Python version stated in #! or Python 2 if #! is missing. The py -3 script.py launches the Python 3.

Save the count as you go - and use validation to enforce it. I hacked this together - for keeping a count of unique votes and counts which keeps coming up!. But this time I have tested my suggestion! (notwithstanding cut/paste errors!).

The 'trick' here is to use the node priority to as the vote count...

The data is:

vote/$issueBeingVotedOn/user/$uniqueIdOfVoter = thisVotesCount, priority=thisVotesCount vote/$issueBeingVotedOn/count = 'user/'+$idOfLastVoter, priority=CountofLastVote

,"vote": {
  ".read" : true
  ,".write" : true
  ,"$issue" : {
    "user" : {
      "$user" : {
        ".validate" : "!data.exists() && 
             newData.val()==data.parent().parent().child('count').getPriority()+1 &&
             newData.val()==newData.GetPriority()" 

user can only vote once && count must be one higher than current count && data value must be same as priority.

      }
    }
    ,"count" : {
      ".validate" : "data.parent().child(newData.val()).val()==newData.getPriority() &&
             newData.getPriority()==data.getPriority()+1 "
    }

count (last voter really) - vote must exist and its count equal newcount, && newcount (priority) can only go up by one.

  }
}

Test script to add 10 votes by different users (for this example, id's faked, should user auth.uid in production). Count down by (i--) 10 to see validation fail.

<script src='https://cdn.firebase.com/v0/firebase.js'></script>
<script>
  window.fb = new Firebase('https:...vote/iss1/');
  window.fb.child('count').once('value', function (dss) {
    votes = dss.getPriority();
    for (var i=1;i<10;i++) vote(dss,i+votes);
  } );

function vote(dss,count)
{
  var user='user/zz' + count; // replace with auth.id or whatever
  window.fb.child(user).setWithPriority(count,count);
  window.fb.child('count').setWithPriority(user,count);
}
</script>

The 'risk' here is that a vote is cast, but the count not updated (haking or script failure). This is why the votes have a unique 'priority' - the script should really start by ensuring that there is no vote with priority higher than the current count, if there is it should complete that transaction before doing its own - get your clients to clean up for you :)

The count needs to be initialised with a priority before you start - forge doesn't let you do this, so a stub script is needed (before the validation is active!).

requests does not handle parsing XML responses, no. XML responses are much more complex in nature than JSON responses, how you'd serialize XML data into Python structures is not nearly as straightforward.

Python comes with built-in XML parsers. I recommend you use the ElementTree API:

import requests
from xml.etree import ElementTree

response = requests.get(url)

tree = ElementTree.fromstring(response.content)

or, if the response is particularly large, use an incremental approach:

    response = requests.get(url, stream=True)
    # if the server sent a Gzip or Deflate compressed response, decompress
    # as we read the raw stream:
    response.raw.decode_content = True

    events = ElementTree.iterparse(response.raw)
    for event, elem in events:
        # do something with `elem`

The external lxml project builds on the same API to give you more features and power still.

I have tried a product called Rummage and it does a good job in giving you some control ... Although it lacks many things that Eziriz offers but price for Rummage is too good...

I found references to an AVAYA/CMS programme file? Totally random, this was in MS Access, nothing to do with AVAYA. I do have AVAYA on my PC, and others don't, so this explains why it worked on my machine and not others - but not how Access got linked to AVAYA. Anyway - I just unchecked the reference and that seems to have fixed the problem

It will contain the actual size of the array as that is what you initialized the array to be when you declared it. Java has no concept of the "logical" size of an array, as far as it is concerned the default value of 0 is just as logical as the values you have manually set.

The code starts file search from root colon, If I want to start search from a specific directory, to avoid going to that directory every time, where I should put one. I did it like

Sub GetFilePath()
FileSelected = "G:\Audits\A2010"
Set myFile = Application.FileDialog(msoFileDialogOpen)
With myFile
.Title = "Choose File"
.AllowMultiSelect = False
If .Show <> -1 Then
Exit Sub
End If
FileSelected = .SelectedItems(1)
End With

ActiveSheet.Range("C14") = FileSelected
End Sub

But it could not start reach from "G:\Audits\A2010"

You can get the ROWID by using the methods given below :

1.Create a new table with auto increment field in it

2.Use Row_Number analytical function to get the sequence based on your requirement.I would prefer this because it helps in situations where you are you want the row_id on ascending or descending manner of a specific field or combination of fields

Sample:Row_Number() Over(Partition by Deptno order by sal desc)

Above sample will give you the sequence number based on highest salary of each department.Partition by is optional and you can remove it according to your requirements

Here's my example in which I work

You can bind this to your function by adding .bind(this) directly to the end of your function definition. You would rewrite your code block as:

setTimeout(function () {
  this.setState({ timePassed: true });
}.bind(this), 1000);

For Lisp and Scheme (hell, functional programming in general), there are few things that provide a more solid foundation than The Little Schemer and The Seasoned Schemer. Both provide a very simple and intuitive introduction to both Scheme and functional programming that proves far simpler for new students or hobbyists than any of the typical volumes that rub off like a nonfiction rendition of War & Peace.

Once they've moved beyond the Schemer series, SICP and On Lisp are both fantastic choices.

You don't mention whether you are using Windows or UNIX.

On UNIX systems, KDevelop is good but I use KDbg because it is easy to use and will also work with apps not developed in KDevelop.

Eclipse is good on both platforms.

On Windows, there is a great package called Wascana Desktop Developer which is Eclipse CDT and MinGW all packaged up and preconfigured nicely for the minimum of pain. Its the best thing I've found for developing GNU code on Windows.

I have used all these debuggers and none of them are as good as MS Dev Studio. Eclipse/Wascana is probably the closest but it does have limitations like you cannot step into DLLs and it doesn't do as good a job at examining variables.

It's very simple, first convert the number to string using the toString() method in JavaScript and then use split() method to convert the string to an array of individual characters.

For example, the number is num, then

const numberDigits = num.toString().split('');

Login into the database. then run the below query

select * from dba_role_privs where grantee = 'SCHEMA_NAME';

All the role granted to the schema will be listed.

Thanks Szilagyi Donat for the answer. This one is taken from same and just where clause added.

My solution is to use Process.GetProcess() for listing all the processes.

By filtering them to contain the processes I want, I can then run Process.Kill() method to stop them:

var chromeDriverProcesses = Process.GetProcesses().
    Where(pr => pr.ProcessName == "chromedriver"); // without '.exe'
    
foreach (var process in chromeDriverProcesses)
{
     process.Kill();
}

Update:

In case if want to use async approach with some useful recent methods from the C# 8 (Async Enumerables), then check this out:

const string processName = "chromedriver"; // without '.exe'
await Process.GetProcesses()
             .Where(pr => pr.ProcessName == processName)
             .ToAsyncEnumerable()
             .ForEachAsync(p => p.Kill());

Note: using async methods doesn't always mean code will run faster, but it will not waste the CPU time and prevent the foreground thread from hanging while doing the operations. In any case, you need to think about what version you might want.

On Windows 10 with Vagrant 2.2.2, setting the environment variable VAGRANT_HOME will ensure that boxes are downloaded to a subfolder of the folder specified for VAGRANT_HOME.

In my case I set VAGRANT_HOME to e:\vagrant_home, and the boxes get stored under e:\vagrant_home\boxes.

This works for me.

That's where the boxes are stored. The virtual machines are being created in the folder configured in Virtual Box. To set the VirtualBox VM storage folder, go to: VirtualBox GUI --> File --> Preferences --> General --> Default Machine Folder.

Try this:

function normal_chars($string)
{
    $string = htmlentities($string, ENT_QUOTES, 'UTF-8');
    $string = preg_replace('~&([a-z]{1,2})(acute|cedil|circ|grave|lig|orn|ring|slash|th|tilde|uml);~i', '$1', $string);
    $string = html_entity_decode($string, ENT_QUOTES, 'UTF-8');
    $string = preg_replace(array('~[^0-9a-z]~i', '~[ -]+~'), ' ', $string);

    return trim($string, ' -');
}

Examples:

echo normal_chars('Álix----_Ãxel!?!?'); // Alix Axel
echo normal_chars('áéíóúÁÉÍÓÚ'); // aeiouAEIOU
echo normal_chars('üÿÄËÏÖÜŸåÅ'); // uyAEIOUYaA
