Within the AD every user has a property memberOf. This contains a list of all groups he belongs to.

Here is a little code example:

// (replace "part_of_user_name" with some partial user name existing in your AD)
var userNameContains = "part_of_user_name";

var identity = WindowsIdentity.GetCurrent().User;
var allDomains = Forest.GetCurrentForest().Domains.Cast<Domain>();

var allSearcher = allDomains.Select(domain =>
{
    var searcher = new DirectorySearcher(new DirectoryEntry("LDAP://" + domain.Name));

    // Apply some filter to focus on only some specfic objects
    searcher.Filter = String.Format("(&(&(objectCategory=person)(objectClass=user)(name=*{0}*)))", userNameContains);
    return searcher;
});

var directoryEntriesFound = allSearcher
    .SelectMany(searcher => searcher.FindAll()
        .Cast<SearchResult>()
        .Select(result => result.GetDirectoryEntry()));

var memberOf = directoryEntriesFound.Select(entry =>
{
    using (entry)
    {
        return new
        {
            Name = entry.Name,
            GroupName = ((object[])entry.Properties["MemberOf"].Value).Select(obj => obj.ToString())
        };
    }
});

foreach (var item in memberOf)
{
    Debug.Print("Name = " + item.Name);
    Debug.Print("Member of:");

    foreach (var groupName in item.GroupName)
    {
        Debug.Print("   " + groupName);
    }

    Debug.Print(String.Empty);
}
}

I use simple grep inside function in bash script to receive properties from .properties file.

This properties file I use in two places - to setup dev environment and as application parameters.

I believe that grep may work slow in big loops but it solves my needs when I want to prepare dev environment.

Hope, someone will find this useful.

Example:

File: setup.sh

#!/bin/bash

ENV=${1:-dev}

function prop {
    grep "${1}" env/${ENV}.properties|cut -d'=' -f2
}

docker create \
    --name=myapp-storage \
    -p $(prop 'app.storage.address'):$(prop 'app.storage.port'):9000 \
    -h $(prop 'app.storage.host') \
    -e STORAGE_ACCESS_KEY="$(prop 'app.storage.access-key')" \
    -e STORAGE_SECRET_KEY="$(prop 'app.storage.secret-key')" \
    -e STORAGE_BUCKET="$(prop 'app.storage.bucket')" \
    -v "$(prop 'app.data-path')/storage":/app/storage \
    myapp-storage:latest

docker create \
    --name=myapp-database \
    -p "$(prop 'app.database.address')":"$(prop 'app.database.port')":5432 \
    -h "$(prop 'app.database.host')" \
    -e POSTGRES_USER="$(prop 'app.database.user')" \
    -e POSTGRES_PASSWORD="$(prop 'app.database.pass')" \
    -e POSTGRES_DB="$(prop 'app.database.main')" \
    -e PGDATA="/app/database" \
    -v "$(prop 'app.data-path')/database":/app/database \
    postgres:9.5

If you are interested in only selecting one column this will work.

df[["item1"]].to_dict("records")

The below will NOT work and produces a TypeError: unsupported type: . I believe this is because it is trying to convert a series to a dict and not a Data Frame to a dict.

df["item1"].to_dict("records")

I had a requirement to only select one column and convert it to a list of dicts with the column name as the key and was stuck on this for a bit so figured I'd share.

Changing the index variable i from within the loop is unlikely to do what you expect. You may need to use a while loop instead, and control the incrementing of the loop variable yourself. Each time around the for loop, i is reassigned with the next value from range(). So something like:

i = 2
while i < n:
    if(something):
        do something
    else:
        do something else
        i = 2 # restart the loop
        continue
    i += 1

In my example, the continue statement jumps back up to the top of the loop, skipping the i += 1 statement for that iteration. Otherwise, i is incremented as you would expect (same as the for loop).

If you want to keep using the Array.prototype.include() in javascript you can use this script: github-script-ie-include That converts automatically the include() to the match() function if it detects IE.

Other option is using always thestring.match(Regex(expression))

Consider your data is into column A and will write coding now

Sub deletezeros()
    Dim c As Range
    Dim searchrange As Range
    Dim i As Long

    Set searchrange = ActiveSheet.Range("A1", ActiveSheet.Range("A65536").End(xlUp))

    For i = searchrange.Cells.Count To 1 Step -1
        Set c = searchrange.Cells(i)
        If c.Value = "0" Then c.EntireRow.delete
    Next i
End Sub

I followed the solution by poke with a minor adjustment in the end. My steps follow
- git fetch --prune;
- git branch -a printing the following
    master
    branch
    remotes/origin/HEAD -> origin/master
    remotes/origin/master
    remotes/origin/branch (remote branch to remove)
- git push origin --delete branch.
Here, the branch to remove is not named as remotes/origin/branch but simply branch. And the branch is removed.

np.append needs the array as the first argument and the list you want to append as the second:

mean_data = np.append(mean_data, [ur, ua, np.mean(data[samepoints,-1])])

As @gaurang171 mentioned, we can use .closest() which will return the first ancestor, or the closest to our delete button, and use .remove() to remove it.

This is how we can implement it using jQuery click event instead of using JavaScript onclick.

Update the security group of that instance. Your local IP must have updated. Every time it’s IP flips. You will have to go update the Security group.

I know DOS and cmd prompt DOES NOT LIKE spaces in folder names. Your code starts with

Change the folder name and *.exe name. Hope this helps

Here is a working pandas subplot example, where modes is the column names of the dataframe.

I use both PuTTY and Bitvise SSH Client. PuTTY handles screen sessions better, but Bitvise automatically opens up a SFTP window so you can transfer files just like you would with an FTP client.

For Kotlin on fragment just do this

activity?.runOnUiThread(Runnable {
        //on main thread
    })

require 'trollop'

opts = Trollop::options do
  opt :output, "Output file", :type => String
  opt :input, "Input file", :type => String
  opt :ss, "String to search", :type => String
  opt :rs, "String to replace", :type => String
end

text = File.read(opts.input)
text.gsub!(opts.ss, opts.rs)
File.open(opts.output, 'w') { |f| f.write(text) }

It would probably be easier to just fake it by using a div. Just make sure you set the height if its empty so that it can actually appear. Say for instance you want it to be 50px tall set the div height to 50px.

<div id="rightflower">
<div id="divImg"></div> 
</div>

And in your style sheet just add the background and its properties, height and width, and what ever positioning you had in mind.

grep -q "something" file
[[ !? -eq 0 ]] && echo "yes" || echo "no"

For scripting purposes, I've found that curl command can do it, for example:

$ curl -s localhost:80 >/dev/null && echo Connected. || echo Fail.
Connected.
$ curl -s localhost:123 >/dev/null && echo Connected. || echo Fail.
Fail.

Possibly it may not won't work for all services, as curl can return different error codes in some cases (as per comment), so adding the following condition could work in reliable way:

[ "$(curl -sm5 localhost:8080 >/dev/null; echo $?)" != 7 ] && echo OK || echo FAIL

^{Note: Added -m5 to set maximum connect timeout of 5 seconds.}

If you would like to check also whether host is valid, you need to check for 6 exit code as well:

$ curl -m5 foo:123; [ $? != 6 -a $? != 7 ] && echo OK || echo FAIL
curl: (6) Could not resolve host: foo
FAIL

To troubleshoot the returned error code, simply run: curl host:port, e.g.:

$ curl localhost:80
curl: (7) Failed to connect to localhost port 80: Connection refused

See: man curl for full list of exit codes.

SQLDeveloper can do this.

Use this instead:

$('#save').click(function () {
    $('#mytable').find('input[type="checkbox"]:checked') //...
});

Let me explain you what the selector does: input[type="checkbox"] means that this will match each <input /> with type attribute type equals to checkbox After that: :checked will match all checked checkboxes.

You can loop over these checkboxes with:

$('#save').click(function () {
    $('#mytable').find('input[type="checkbox"]:checked').each(function () {
       //this is the current checkbox
    });
});

Here is demo in JSFiddle.

And here is a demo which solves exactly your problem http://jsfiddle.net/DuE8K/1/.

$('#save').click(function () {
    $('#mytable').find('tr').each(function () {
        var row = $(this);
        if (row.find('input[type="checkbox"]').is(':checked') &&
            row.find('textarea').val().length <= 0) {
            alert('You must fill the text area!');
        }
    });
});

You can have a look at Jansson

The website states the following: Jansson is a C library for encoding, decoding and manipulating JSON data. It features:

• Simple and intuitive API and data model
• Can both encode to and decode from JSON
• Comprehensive documentation
• No dependencies on other libraries
• Full Unicode support (UTF-8)
• Extensive test suite

You can use print df.describe().to_string() to force it to show the whole table. (You can use to_string() like this for any DataFrame. The result of describe is just a DataFrame itself.)

The 8 is the number of rows in the DataFrame holding the "description" (because describe computes 8 statistics, min, max, mean, etc.).

If you are using Adobe Acrobat X to make the form, set all the fields as you want them, then click File, Save As, Reader Extended PDF, Enable Additional Features. The resulting PDF form can be saved when filled in, if opened in versions of Adobe Reader before XI.

I would suggest to use a variable instead of a public field:

public class Variables
{
   private static string name = "";

   public static string Name
   { 
        get { return name; }
        set { name = value; }

   }
}

From another class, you call your variable like this:

public class Main
{
    public void DoSomething()
    {
         string var = Variables.Name;
    }
}

While ln -s is the obvious easiest fix, a piece of explanation:

Because of a conflict with another package, the executable from the Ubuntu repositories is called nodejs instead of node. Keep this in mind as you are running software.

This advice comes up, when installing sudo apt-get install nodejs.

So some other known tool (I don't know what it does. While being known to ubuntu repositories, it is not installed by default in 16.04) occupies that namespace.

Would have been nice, if Ubuntu had offered an advice how to fix this 'cleanly', if not by doing by hand what otherwise the package would do. (a collision remains a collision... if+when it would occur)

If your dates column does not contain time information, you could get away with:

WHERE dates BETWEEN '20121211' and '20121213'

However, given your dates column is actually datetime, you want this

WHERE dates >= '20121211'
  AND dates < '20121214'  -- i.e. 00:00 of the next day

Another option for SQL Server 2008 onwards that retains SARGability (ability to use index for good performance) is:

WHERE CAST(dates as date) BETWEEN '20121211' and '20121213'

Note: always use ISO-8601 format YYYYMMDD with SQL Server for unambiguous date literals.

For Ubuntu 20.04 users with php-fpm I fixed the issue by adding the full path in the php conf:

edit /etc/php/7.4/fpm/conf.d/20-mysqli.ini

and replace

extension=mysqli.so

with:

extension=/usr/lib/php/20190902/mysqli.so

Try with the fully qualified name for the resource:

private static final String FILENAME = "resources/skyscrapper";

I had the same problem myself. I'm not sure if you got it to work though, but what I had to was:

EditText cypherInput;
cypherInput = (EditText)findViewById(R.id.input_cipherValue);
int cypher = Integer.parseInt(cypherInput.getText().toString());

The third line of code caused the app to crash without using the .getText() before the .toString().

Just for reference, here is my XML:

<EditText
    android:id="@+id/input_cipherValue"
    android:inputType="number"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" />

I think you are looking for qsort.
qsort function is the implementation of quicksort algorithm found in stdlib.h in C/C++.

Here is the syntax to call qsort function:

void qsort(void *base, size_t nmemb, size_t size,int (*compar)(const void *, const void *));

List of arguments:

base: pointer to the first element or base address of the array
nmemb: number of elements in the array
size: size in bytes of each element
compar: a function that compares two elements

Here is a code example which uses qsort to sort an array:

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

int arr[] = { 33, 12, 6, 2, 76 };

// compare function, compares two elements
int compare (const void * num1, const void * num2) {
   if(*(int*)num1 > *(int*)num2)
    return 1;
   else
    return -1;
}

int main () {
   int i;

   printf("Before sorting the array: \n");
   for( i = 0 ; i < 5; i++ ) {
      printf("%d ", arr[i]);
   }
   // calling qsort
   qsort(arr, 5, sizeof(int), compare);

   printf("\nAfter sorting the array: \n");
   for( i = 0 ; i < 5; i++ ) {   
      printf("%d ", arr[i]);
   }
  
   return 0;
}

You can type man 3 qsort in Linux/Mac terminal to get a detailed info about qsort.
Link to qsort man page

plt.imshow just finishes drawing a picture instead of printing it. If you want to print the picture, you just need to add plt.show.

Much simpler approach is to use OdeToCode.UseNodeModules Nuget package. I just tested it with .Net Core 3.0. All you need to do is add the package to the solution and reference it in the Configure method of the Startup class:

app.UseNodeModules();

I learned about it from the excellent Building a Web App with ASP.NET Core, MVC, Entity Framework Core, Bootstrap, and Angular Pluralsight course by Shawn Wildermuth.

Converting to floating point and back seems like a huge waste of time at the CPU level.

Ian Nelson's solution:

int pageCount = (records + recordsPerPage - 1) / recordsPerPage;

Can be simplified to:

int pageCount = (records - 1) / recordsPerPage + 1;

AFAICS, this doesn't have the overflow bug that Brandon DuRette pointed out, and because it only uses it once, you don't need to store the recordsPerPage specially if it comes from an expensive function to fetch the value from a config file or something.

I.e. this might be inefficient, if config.fetch_value used a database lookup or something:

int pageCount = (records + config.fetch_value('records per page') - 1) / config.fetch_value('records per page');

This creates a variable you don't really need, which probably has (minor) memory implications and is just too much typing:

int recordsPerPage = config.fetch_value('records per page')
int pageCount = (records + recordsPerPage - 1) / recordsPerPage;

This is all one line, and only fetches the data once:

int pageCount = (records - 1) / config.fetch_value('records per page') + 1;

This is what I would do if passed a string buffer to fill and I knew the buffer was big enough (ie at least 16 characters long):

sprintf(buffer, "%d.%d.%d.%d",
  (ip >> 24) & 0xFF,
  (ip >> 16) & 0xFF,
  (ip >>  8) & 0xFF,
  (ip      ) & 0xFF);

This would be slightly faster than creating a byte array first, and I think it is more readable. I would normally use snprintf, but IP addresses can't be more than 16 characters long including the terminating null.

Alternatively if I was asked for a function returning a char*:

char* IPAddressToString(int ip)
{
  char[] result = new char[16];

  sprintf(result, "%d.%d.%d.%d",
    (ip >> 24) & 0xFF,
    (ip >> 16) & 0xFF,
    (ip >>  8) & 0xFF,
    (ip      ) & 0xFF);

  return result;
}

In Java I used to work around this by using a map and implementing my own take on Key-Value coding.

Move your .android to wherever you want it to.

Then, create a symlink like this:

# In your home folder
$ ln -s /path/to/.android/ .

This simply tells Linux that whenever the path ~/.android is referenced by any application, link it to /path/to/.android.

Easy peasy lemon squeezy: http://www.php.net/manual/en/function.json-encode.php

<?php
$arr = array('a' => 1, 'b' => 2, 'c' => 3, 'd' => 4, 'e' => 5);

echo json_encode($arr);
?>

There's a post by andyrusterholz at g-m-a-i-l dot c-o-m on the aforementioned page that can also handle complex nested arrays (if that's your thing).

System.out.println(Character.isDigit(mystring.charAt(0));

EDIT: I searched for java docs, looked at methods on string class which can get me 1st character & looked at methods on Character class to see if it has any method to check such a thing.

I think, you could do the same before asking it.

EDI2: What I mean is, try to do things, read/find & if you can't find anything - ask.
I made a mistake when posting it for the first time. isDigit is a static method on Character class.

add android:textAllCaps="false" in xml button It's true with this issue.

For publicly access use like below:

public arr: Criminal[] = [];

You can't remove API functions without breaking the API. If you would, many applications would no longer compile or run at all.

This is the reason that one reference gives:

Reading a line that overflows the array pointed to by s results in undefined behavior. The use of fgets() is recommended.

A timestamp does not have "a format".

The recommended way to deal with timestamps is to use a PreparedStatement where you just pass a placeholder in the SQL and pass a "real" object through the API of your programming language. As I don't know Python, I don't know if it supports PreparedStatements and how the syntax for that would be.

If you want to put a timestamp literal into your generated SQL, you will need to follow some formatting rules when specifying the value (a literal does have a format).

Ivan's method will work, although I'm not 100% sure if it depends on the configuration of the PostgreSQL server.

A configuration (and language) independent solution to specify a timestamp literal is the ANSI SQL standard:

 INSERT INTO some_table 
 (ts_column) 
 VALUES 
 (TIMESTAMP '2011-05-16 15:36:38');

Yes, that's the keyword TIMESTAMP followed by a timestamp formatted in ISO style (the TIMESTAMP keyword defines that format)

The other solution would be to use the to_timestamp() function where you can specify the format of the input literal.

 INSERT INTO some_table 
 (ts_column) 
 VALUES 
 (to_timestamp('16-05-2011 15:36:38', 'dd-mm-yyyy hh24:mi:ss'));

function dec2hex(i)
{
  var result = "0000";
  if      (i >= 0    && i <= 15)    { result = "000" + i.toString(16); }
  else if (i >= 16   && i <= 255)   { result = "00"  + i.toString(16); }
  else if (i >= 256  && i <= 4095)  { result = "0"   + i.toString(16); }
  else if (i >= 4096 && i <= 65535) { result =         i.toString(16); }
  return result
}

Just add new updates from Angular 8.

1. For case if with else, we can use ngIf and ngIfElse.

<ng-template [ngIf]="condition" [ngIfElse]="elseBlock">
  Content to render when condition is true.
</ng-template>
<ng-template #elseBlock>
  Content to render when condition is false.
</ng-template>

2. For case if with then, we can use ngIf and ngIfThen.

<ng-template [ngIf]="condition" [ngIfThen]="thenBlock">
  This content is never showing
</ng-template>
<ng-template #thenBlock>
  Content to render when condition is true.
</ng-template>

3. For case if with then and else, we can use ngIf, ngIfThen, and ngIfElse.

<ng-template [ngIf]="condition" [ngIfThen]="thenBlock" [ngIfElse]="elseBlock">
  This content is never showing
</ng-template>
<ng-template #thenBlock>
  Content to render when condition is true.
</ng-template>
<ng-template #elseBlock>
  Content to render when condition is false.
</ng-template>

Use the

Request.Form[]

for POST variables,

Request.QueryString[]

for GET.

Came across a nice tool for doing this.

node-env-file

Parses and loads environment files (containing ENV variable exports) into Node.js environment, i.e. process.env - Uses this style:

.env

# some env variables

FOO=foo1
BAR=bar1
BAZ=1
QUX=
# QUUX=

There's a ES6 shorthand import, you can reference. More readable and easy to type.

import React, { Component } from 'react';
import { arrayOf, shape, number } from 'prop-types';

class ExampleComponent extends Component {
  static propTypes = {
    annotationRanges: arrayOf(shape({
      start: number,
      end: number,
    })).isRequired,
  }

  static defaultProps = {
     annotationRanges: [],
  }
}

Seems odd to be inserting a value into an automatically incrementing field.

Also, have you tried the insert() method instead of execSQL?

ContentValues insertValues = new ContentValues();
insertValues.put("Description", "Electricity");
insertValues.put("Amount", 500);
insertValues.put("Trans", 1);
insertValues.put("EntryDate", "04/06/2011");
db.insert("CashData", null, insertValues);

I was having the same problem and none of the posted solutions seemed to work and then I found out that it's because ASP.NET renders the CheckBox control as a SPAN with INPUT inside, so the CheckBox ID is actually an ID of a SPAN, not an INPUT, so you should use:

$('#isAgeSelected input')

rather than

$('#isAgeSelected')

and then all methods listed above should work.

A probably convenient way to enter multi-line strings is by using macro's. This only works if quotes and parentheses are balanced and it does not contain 'top level' comma's:

#define MULTI_LINE_STRING(a) #a
const char *text = MULTI_LINE_STRING(
  Using this trick(,) you don't need to use quotes.
  Though newlines and     multiple     white   spaces
  will be replaced by a single whitespace.
);
printf("[[%s]]\n",text);

Compiled with gcc 4.6 or g++ 4.6, this produces: [[Using this trick(,) you don't need to use quotes. Though newlines and multiple white spaces will be replaced by a single whitespace.]]

Note that the , cannot be in the string, unless it is contained within parenthesis or quotes. Single quotes is possible, but creates compiler warnings.

Edit: As mentioned in the comments, #define MULTI_LINE_STRING(...) #__VA_ARGS__ allows the use of ,.

I'm referring to TT's post and suggest the following approach:

Reference the System.Web dll in your model and use System.Web.Caching.Cache

public string[] GetNames()
{ 
    var noms = Cache["names"];
    if(noms == null) 
    {    
        noms = DB.GetNames();
        Cache["names"] = noms; 
    }

    return ((string[])noms);
}

You should not return a value re-read from the cache, since you'll never know if at that specific moment it is still in the cache. Even if you inserted it in the statement before, it might already be gone or has never been added to the cache - you just don't know.

So you add the data read from the database and return it directly, not re-reading from the cache.

Try killing port 8600 with this command:

fuser -k 8600/tcp

That fixed it for me.

You have a few issues with your code:

1. you are missing an open quote on the id of the select element, so: <select name="dbType" id=dbType">

should be <select name="dbType" id="dbType">

2. $('this') should be $(this): there is no need for the quotes inside the paranthesis.

3. use .val() instead of .value() when you want to retrieve the value of an option

4. when u initialize "selection" do it with a var in front of it, unless you already have done it at the beggining of the function

try this:

   $('#dbType').on('change',function(){
        if( $(this).val()==="other"){
        $("#otherType").show()
        }
        else{
        $("#otherType").hide()
        }
    });

http://jsfiddle.net/ks6cv/

UPDATE for use with switch:

$('#dbType').on('change',function(){
     var selection = $(this).val();
    switch(selection){
    case "other":
    $("#otherType").show()
   break;
    default:
    $("#otherType").hide()
    }
});

UPDATE with links for jQuery and jQuery-UI:

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js" ></script>
<script src="//ajax.googleapis.com/ajax/libs/jqueryui/1.10.2/jquery-ui.min.js"></script>??

Here's my go at answering this,

so first you will need to convert the timestamp to an actual Ruby Date/Time. If you receive it just as a string or int from facebook, you will need to do something like this:

my_date = Time.at(timestamp_from_facebook.to_i)

OK, so now assuming you already have your date object...

to_formatted_s is a handy Ruby function that turns dates into formatted strings.

Here are some examples of its usage:

time = Time.now                     # => Thu Jan 18 06:10:17 CST 2007    

time.to_formatted_s(:time)          # => "06:10"
time.to_s(:time)                    # => "06:10"    

time.to_formatted_s(:db)            # => "2007-01-18 06:10:17"
time.to_formatted_s(:number)        # => "20070118061017"
time.to_formatted_s(:short)         # => "18 Jan 06:10"
time.to_formatted_s(:long)          # => "January 18, 2007 06:10"
time.to_formatted_s(:long_ordinal)  # => "January 18th, 2007 06:10"
time.to_formatted_s(:rfc822)        # => "Thu, 18 Jan 2007 06:10:17 -0600"

As you can see: :db, :number, :short ... are custom date formats.

To add your own custom format, you can create this file: config/initializers/time_formats.rb and add your own formats there, for example here's one:

Date::DATE_FORMATS[:month_day_comma_year] = "%B %e, %Y" # January 28, 2015

Where :month_day_comma_year is your format's name (you can change this to anything you want), and where %B %e, %Y is unix date format.

Here's a quick cheatsheet on unix date syntax, so you can quickly setup your custom format:

From http://linux.die.net/man/3/strftime    

  %a - The abbreviated weekday name (``Sun'')
  %A - The  full  weekday  name (``Sunday'')
  %b - The abbreviated month name (``Jan'')
  %B - The  full  month  name (``January'')
  %c - The preferred local date and time representation
  %d - Day of the month (01..31)
  %e - Day of the month without leading 0 (1..31) 
  %g - Year in YY (00-99)
  %H - Hour of the day, 24-hour clock (00..23)
  %I - Hour of the day, 12-hour clock (01..12)
  %j - Day of the year (001..366)
  %m - Month of the year (01..12)
  %M - Minute of the hour (00..59)
  %p - Meridian indicator (``AM''  or  ``PM'')
  %S - Second of the minute (00..60)
  %U - Week  number  of the current year,
          starting with the first Sunday as the first
          day of the first week (00..53)
  %W - Week  number  of the current year,
          starting with the first Monday as the first
          day of the first week (00..53)
  %w - Day of the week (Sunday is 0, 0..6)
  %x - Preferred representation for the date alone, no time
  %X - Preferred representation for the time alone, no date
  %y - Year without a century (00..99)
  %Y - Year with century
  %Z - Time zone name
  %% - Literal ``%'' character    

   t = Time.now
   t.strftime("Printed on %m/%d/%Y")   #=> "Printed on 04/09/2003"
   t.strftime("at %I:%M%p")            #=> "at 08:56AM"

Hope this helped you. I've also made a github gist of this little guide, in case anyone prefers.

If using a third party library is an option, there is jOOU (a spin off library from jOOQ), which offers wrapper types for unsigned integer numbers in Java. That's not exactly the same thing as having primitive type (and thus byte code) support for unsigned types, but perhaps it's still good enough for your use-case.

import static org.joou.Unsigned.*;

// and then...
UByte    b = ubyte(1);
UShort   s = ushort(1);
UInteger i = uint(1);
ULong    l = ulong(1);

All of these types extend java.lang.Number and can be converted into higher-order primitive types and BigInteger.

(Disclaimer: I work for the company behind these libraries)

You don't have to bind parameters if you use query builder or eloquent ORM. However, if you use DB::raw(), ensure that you binding the parameters.

Try the following:

$array = array(1,2,3);       $query = DB::table('offers');             $query->select('id', 'business_id', 'address_id', 'title', 'details', 'value', 'total_available', 'start_date', 'end_date', 'terms', 'type', 'coupon_code', 'is_barcode_available', 'is_exclusive', 'userinformations_id', 'is_used');             $query->leftJoin('user_offer_collection', function ($join) use ($array)             {                 $join->on('user_offer_collection.offers_id', '=', 'offers.id')                       ->whereIn('user_offer_collection.user_id', $array);             });       $query->get(); 

The problem is you typed the wrong file extension for excel file. you used .xsl instead of xls.

I know i came in late but it can help future readers of this post.

I know that this has been asked more than three years ago. But the answer accepted is not extremely useful.

The following code is more useful.

<?php
$File = 'loginevents.csv';

$arrResult  = array();
$handle     = fopen($File, "r");
if(empty($handle) === false) {
    while(($data = fgetcsv($handle, 1000, ",")) !== FALSE){
        $arrResult[] = $data;
    }
    fclose($handle);
}
print_r($arrResult);
?>

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

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

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

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

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

color=(200, 100, 255) # sample of a color 
img = np.full((100, 100, 3), color, np.uint8)

You really don't need jQuery for this.

var myarr = ["I", "like", "turtles"];
var arraycontainsturtles = (myarr.indexOf("turtles") > -1);

Hint: indexOf returns a number, representing the position where the specified searchvalue occurs for the first time, or -1 if it never occurs

or

function arrayContains(needle, arrhaystack)
{
    return (arrhaystack.indexOf(needle) > -1);
}

It's worth noting that array.indexOf(..) is not supported in IE < 9, but jQuery's indexOf(...) function will work even for those older versions.

A very important place where it is REQUIRED to use the key => value pair in foreach loop is to be mentioned. Suppose you would want to add a new/sub-element to an existing item (in another key) in the $features array. You should do the following:

foreach($features as $key => $feature) {
    $features[$key]['new_key'] = 'new value';  
} 

Instead of this:

foreach($features as $feature) {
    $feature['new_key'] = 'new value';  
} 

The big difference here is that, in the first case you are accessing the array's sub-value via the main array itself with a key to the element which is currently being pointed to by the array pointer.

While in the second (which doesn't work for this purpose) you are assigning the sub-value in the array to a temporary variable $feature which is unset after each loop iteration.

Short answer: No. Use WebM or Ogg instead.

This article covers just about everything you need to know about the <video> element, including which browsers support which container formats and codecs.

I can't believe that no one mentioned that MySQL doesn't support Common Table Expressions (CTE) / "with" statements. It's a pretty annoying difference.

you can try writing the command using 'sudo':

sudo mkdir DirName

After looking at your method, I used this method to solve it.

class Register(forms.Form):
    username = forms.CharField(label='???', max_length=32)
    email = forms.EmailField(label='??', max_length=64)
    password = forms.CharField(label="??", min_length=6, max_length=16)
    captcha = forms.CharField(label="???", max_length=4)

def __init__(self, *args, **kwargs):
    super().__init__(*args, **kwargs)
    for field_name in self.fields:
        field = self.fields.get(field_name)
        self.fields[field_name].widget.attrs.update({
            "placeholder": field.label,
            'class': "input-control"
        })

Your PHP array is defined as:

$arr = array ('resonse'=>'error','comment'=>'test comment here');

Notice the mispelling "resonse". Also, as RaYell has mentioned, you have to use data instead of json in your success function because its parameter is currently data.

Try editing your PHP file to change the spelling form resonse to response. It should work then.

If you want to cast it to specific type (e.g. within tests) you can use ReadAsAsync extension method:

object yourTypeInstance = await response.Content.ReadAsAsync(typeof(YourType));

or following for synchronous code:

object yourTypeInstance = response.Content.ReadAsAsync(typeof(YourType)).Result;

Update: there is also generic option of ReadAsAsync<> which returns specific type instance instead of object-declared one:

YourType yourTypeInstance = await response.Content.ReadAsAsync<YourType>();

i was having the same issue while generating the classes from wsimport goal. Instead of using jaxws:wsimport goal in eclipse Maven Build i was using clean compile install that was not able to generate code from wsdl file. Thanks to above example. Run jaxws:wsimport goal from Eclipse ide and it will work

Installation of Maven doesn't create the settings.xml file. You have to create it on your own. Just put it in your .m2 directory where you expected it, see http://maven.apache.org/settings.html for reference. The m2eclipse plugin will use the same settings file as the command line.

At the time of this post all major browsers disable CSS transitions if you try to change the display property, but CSS animations still work fine so we can use them as a workaround.

Example Code (you can apply it to your menu accordingly) Demo:

Add the following CSS to your stylesheet:

@-webkit-keyframes fadeIn {
    from { opacity: 0; }
      to { opacity: 1; }
}
@keyframes fadeIn {
    from { opacity: 0; }
      to { opacity: 1; }
}

Then apply the fadeIn animation to the child on parent hover (and of course set display: block):

.parent:hover .child {
    display: block;
    -webkit-animation: fadeIn 1s;
    animation: fadeIn 1s;
}

Update 2019 - Method that also supports fading out:

(Some JavaScript code is required)

// We need to keep track of faded in elements so we can apply fade out later in CSS_x000D_

Just download and install openSSH for windows. It is open source, and it makes your cmd ssh ready. A quick google search will give you a tutorial on how to install it, should you need it.

After it is installed you can just go ahead and generate your public key if you want to put in on a server. You generate it by running:

ssh-keygen -t rsa

After that you can just can just press enter, it will automatically assign a name for the key (example: id_rsa.pub)

Ok, as this thread appears among the first results of google and for other users having the same question, you don't have to reivent the wheel as pointed by trueboroda there is the ng2-file-upload library which simplify this process of uploading a file with angular 6 and 7 all you need to do is:

Install the latest Angular CLI

yarn add global @angular/cli

Then install rx-compat for compatibility concern

npm install rxjs-compat --save

Install ng2-file-upload

npm install ng2-file-upload --save

Import FileSelectDirective Directive in your module.

import { FileSelectDirective } from 'ng2-file-upload';

Add it to [declarations] under @NgModule:
declarations: [ ... FileSelectDirective , ... ]

In your component

import { FileUploader } from 'ng2-file-upload/ng2-file-upload';
...

export class AppComponent implements OnInit {

   public uploader: FileUploader = new FileUploader({url: URL, itemAlias: 'photo'});
}

Template

<input type="file" name="photo" ng2FileSelect [uploader]="uploader" />

proposed solution edit works if you replace the row

Set rDst = ThisWorkbook.Sheets("SomeSheet").Cells("YourCell").Resize(rSrc.Rows.Count, rSrc.Columns.Count)

with

Set rDst = ThisWorkbook.Sheets("SomeSheet").Range("YourRange").Resize(rSrc.Rows.Count, rSrc.Columns.Count)

Assuming the ID is unique:

var result = xmldoc.Element("Customers")
                   .Elements("Customer")
                   .Single(x => (int?)x.Attribute("ID") == 2);

You could also use First, FirstOrDefault, SingleOrDefault or Where, instead of Single for different circumstances.

The And operator will check all conditions in the statement before continuing, whereas the Andalso operator will stop if it knows the condition is false. For example:

if x = 5 And y = 7

Checks if x is equal to 5, and if y is equal to 7, then continues if both are true.

if x = 5 AndAlso y = 7

Checks if x is equal to 5. If it's not, it doesn't check if y is 7, because it knows that the condition is false already. (This is called short-circuiting.)

Generally people use the short-circuiting method if there's a reason to explicitly not check the second part if the first part is not true, such as if it would throw an exception if checked. For example:

If Not Object Is Nothing AndAlso Object.Load()

If that used And instead of AndAlso, it would still try to Object.Load() even if it were nothing, which would throw an exception.

try setting the utf-8 encoding in your page:

header('content-type:text/html;charset=utf-8');

this works for me:

$arr = array('tag' => 'Odómetro');
$encoded = json_encode($arr);
$decoded = json_decode($encoded);
echo $decoded->{'tag'};

Every answer refering to SuppressWarningsFilter is missing an important detail. You can only use the all-lowercase id if it's defined as such in your checkstyle-config.xml. If not you must use the original module name.

For instance, if in my checkstyle-config.xml I have:

<module name="NoWhitespaceBefore"/>

I cannot use:

@SuppressWarnings({"nowhitespacebefore"})

I must, however, use:

@SuppressWarnings({"NoWhitespaceBefore"})

In order for the first syntax to work, the checkstyle-config.xml should have:

<module name="NoWhitespaceBefore">
  <property name="id" value="nowhitespacebefore"/>
</module>

This is what worked for me, at least in the CheckStyle version 6.17.

If everything else fails, check if the jar file in your local .m2 repository is indeed valid and not corrupted. In my case, the file had not been fully downloaded.

If you desire to use Python 3, you can use the following:

Exactly the same way you add HTML tags. Echo it

Simple example using a class :

class test {

    public function works($other_parameter, $function_as_parameter)
    {

        return $function_as_parameter($other_parameter) ;

    }

}

$obj = new test() ;

echo $obj->works('working well',function($other_parameter){


    return $other_parameter;


});

In ES6 you can use Math.sign function to determine if,

1. its +ve no
2. its -ve no
3. its zero (0)
4. its NaN


console.log(Math.sign(1))        // prints 1 
console.log(Math.sign(-1))       // prints -1
console.log(Math.sign(0))        // prints 0
console.log(Math.sign("abcd"))   // prints NaN

We actually have some notification code in our product that uses TLS to send mail if it is available.

You will need to set the Java Mail properties. You only need the TLS one but you might need SSL if your SMTP server uses SSL.

Properties props = new Properties();
props.put("mail.smtp.starttls.enable","true");
props.put("mail.smtp.auth", "true");  // If you need to authenticate
// Use the following if you need SSL
props.put("mail.smtp.socketFactory.port", d_port);
props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
props.put("mail.smtp.socketFactory.fallback", "false");

You can then either pass this to a JavaMail Session or any other session instantiator like Session.getDefaultInstance(props).

curl -sSL https://deb.nodesource.com/gpgkey/nodesource.gpg.key | sudo apt-key add -
# wget can also be used:
# wget --quiet -O - https://deb.nodesource.com/gpgkey/nodesource.gpg.key | sudo apt-key add -

Add the desired NodeSource repository:

# Replace with the branch of Node.js or io.js you want to install: node_6.x, node_12.x, etc...
VERSION=node_12.x
# The below command will set this correctly, but if lsb_release isn't available, you can set it manually:
# - For Debian distributions: jessie, sid, etc...
# - For Ubuntu distributions: xenial, bionic, etc...
# - For Debian or Ubuntu derived distributions your best option is to use the codename corresponding to the upstream release your distribution is based off. This is an advanced scenario and unsupported if your distribution is not listed as supported per earlier in this README.
DISTRO="$(lsb_release -s -c)"
echo "deb https://deb.nodesource.com/$VERSION $DISTRO main" | sudo tee /etc/apt/sources.list.d/nodesource.list
echo "deb-src https://deb.nodesource.com/$VERSION $DISTRO main" | sudo tee -a /etc/apt/sources.list.d/nodesource.list

Update package lists and install Node.js:

sudo apt-get update
sudo apt-get install nodejs

Custom serialization and deserialization.

"from_json" (class method) builds a Model object based on json data.

"deserialize" could be called only on instance, and merge all data from json into Model instance.

"serialize" - recursive serialization

__write_only__ property is needed to define write only properties ("password_hash" for example).

class Serializable(object):
    __exclude__ = ('id',)
    __include__ = ()
    __write_only__ = ()

    @classmethod
    def from_json(cls, json, selfObj=None):
        if selfObj is None:
            self = cls()
        else:
            self = selfObj
        exclude = (cls.__exclude__ or ()) + Serializable.__exclude__
        include = cls.__include__ or ()
        if json:
            for prop, value in json.iteritems():
                # ignore all non user data, e.g. only
                if (not (prop in exclude) | (prop in include)) and isinstance(
                        getattr(cls, prop, None), QueryableAttribute):
                    setattr(self, prop, value)
        return self

    def deserialize(self, json):
        if not json:
            return None
        return self.__class__.from_json(json, selfObj=self)

        output = []
        for li in object_list:
            if isinstance(li, Serializable):
                output.append(li.serialize())
            else:
                output.append(li)
        return output

    def serialize(self, **kwargs):

        # init write only props
        if len(getattr(self.__class__, '__write_only__', ())) == 0:
            self.__class__.__write_only__ = ()

        # loop trough all accessible properties
        for key in iterable:

Hmmm -- since this is handled by the JVM, I delved into the OpenJDK VM source code a little bit, thinking that maybe what's done by OpenJDK mimics what's done by Java 6 and prior. It isn't reassuring that there's a way to do this other than on Windows.

On Windows, OpenJDK's get_temp_directory() function makes a Win32 API call to GetTempPath(); this is how on Windows, Java reflects the value of the TMP environment variable.

On Linux and Solaris, the same get_temp_directory() functions return a static value of /tmp/.

I don't know if the actual JDK6 follows these exact conventions, but by the behavior on each of the listed platforms, it seems like they do.

On my projects i give all rows the class "borders" which I want it to display more like a table with even borders. Giving each child element a border on the bottom and right and the first element of each row a left border will make all of your boxes have an even border:

First give all of the rows children a border on the right and bottom

.borders div{
    border-right:1px solid #999;
    border-bottom:1px solid #999;
}

Next give the first child of each or a left border

.borders div:first-child{
    border-left:
    1px solid #999;
}

Last make sure to clear the borders for their child elements

.borders div > div{
    border:0;
}

HTML:

<div class="row borders">
    <div class="col-xs-5 col-md-2">Email</div>
    <div class="col-xs-7 col-md-4">[email protected]</div>
    <div class="col-xs-5 col-md-2">Phone</div>
    <div class="col-xs-7 col-md-4">555-123-4567</div>
</div>

We have found that adding the Apptentive cocoa pod to an existing Xcode project may potentially not include some of our required frameworks.

Check your linker flags:

Target > Build Settings > Other Linker Flags 

You should see -lApptentiveConnect listed as a linker flag:

... -ObjC -lApptentiveConnect ... 

You should also see our required Frameworks listed:

• Accelerate
• CoreData
• CoreText
• CoreGraphics
• CoreTelephony
• Foundation
• QuartzCore
• StoreKit
• SystemConfiguration

• UIKit

  -ObjC -lApptentiveConnect -framework Accelerate -framework CoreData -framework CoreGraphics -framework CoreText -framework Foundation -framework QuartzCore -framework SystemConfiguration -framework UIKit -framework CoreTelephony -framework StoreKit  

I like the example given by Active State using python. Here is the full link. I added the simple log in part from the link but you can get the gist of what you could do.

import telnetlib

prdLogBox='142.178.1.3'
uid = 'uid'
pwd = 'yourpassword'

tn = telnetlib.Telnet(prdLogBox)
tn.read_until("login: ")
tn.write(uid + "\n")
tn.read_until("Password:")
tn.write(pwd + "\n")
tn.write("exit\n")
tn.close()

I don’t have 6.2 installed but I don’t think 6.3 is any different in this regard:

dataUsingEncoding returns an optional, so you need to unwrap that.

NSDataBase64EncodingOptions.fromRaw has been replaced with NSDataBase64EncodingOptions(rawValue:). Slightly surprisingly, this is not a failable initializer so you don’t need to unwrap it.

But since NSData(base64EncodedString:) is a failable initializer, you need to unwrap that.

Btw, all these changes were suggested by Xcode migrator (click the error message in the gutter and it has a “fix-it” suggestion).

Final code, rewritten to avoid force-unwraps, looks like this:

import Foundation

let str = "iOS Developer Tips encoded in Base64"
println("Original: \(str)")

let utf8str = str.dataUsingEncoding(NSUTF8StringEncoding)

if let base64Encoded = utf8str?.base64EncodedStringWithOptions(NSDataBase64EncodingOptions(rawValue: 0)) 
{

    println("Encoded:  \(base64Encoded)")

    if let base64Decoded = NSData(base64EncodedString: base64Encoded, options:   NSDataBase64DecodingOptions(rawValue: 0))
                          .map({ NSString(data: $0, encoding: NSUTF8StringEncoding) })
    {
        // Convert back to a string
        println("Decoded:  \(base64Decoded)")
    }
}

(if using Swift 1.2 you could use multiple if-lets instead of the map)

Swift 5 Update:

import Foundation

let str = "iOS Developer Tips encoded in Base64"
print("Original: \(str)")

let utf8str = str.data(using: .utf8)

if let base64Encoded = utf8str?.base64EncodedString(options: Data.Base64EncodingOptions(rawValue: 0)) {
    print("Encoded: \(base64Encoded)")

    if let base64Decoded = Data(base64Encoded: base64Encoded, options: Data.Base64DecodingOptions(rawValue: 0))
    .map({ String(data: $0, encoding: .utf8) }) {
        // Convert back to a string
        print("Decoded: \(base64Decoded ?? "")")
    }
}

You can iterate through the key-value pair and write it into file

pair = {'name': name,'location': location}
with open('F:\\twitter.json', 'a') as f:
     f.writelines('{}:{}'.format(k,v) for k, v in pair.items())
     f.write('\n')

It appears the following answer no longer works, and Facebook no longer accepts parameters on the Feed Dialog links

You can use the Feed Dialog via URL to emulate the behavior of Sharer.php, but it's a little more complicated. You need a Facebook App setup with the Base URL of the URL you plan to share configured. Then you can do the following:

1) Create a link like:

   http://www.facebook.com/dialog/feed?app_id=[FACEBOOK_APP_ID]' +
        '&link=[FULLY_QUALIFIED_LINK_TO_SHARE_CONTENT]' +
        '&picture=[LINK_TO_IMAGE]' +
        '&name=' + encodeURIComponent('[CONTENT_TITLE]') +
        '&caption=' + encodeURIComponent('[CONTENT_CAPTION]) +
        '&description=' + encodeURIComponent('[CONTENT_DESCRIPTION]') +
        '&redirect_uri=' + FBVars.baseURL + '[URL_TO_REDIRECT_TO_AFTER_SHARE]' +
        '&display=popup';

(obviously replace the [CONTENT] with the appropriate content. Documentation here: https://developers.facebook.com/docs/reference/dialogs/feed)

2) Open that link in a popup window with JavaScript on click of the share link

3) I like to create file (i.e. popupclose.html) to redirect users back to when they finish sharing, this file will contain <script>window.close();</script> to close the popup window

The only downside of using the Feed Dialog (besides setup) is that, if you manage Pages as well, you don't have the ability to choose to share via a Page, only a regular user account can share. And it can give you some really cryptic error messages, most of them are related to the setup of your Facebook app or problems with either the content or URL you are sharing.

SELECT * FROM EMP WHERE SAL=(SELECT MAX(SAL) FROM EMP WHERE SAL<(SELECT MAX(SAL) FROM EMP));

(OR) SELECT ENAME ,SAL FROM EMP ORDER BY SAL DESC;

(OR) SELECT * FROM(SELECT ENAME,SAL ,DENSE_RANK() OVER(PARTITION BY DEPTNO ORDER BY SAL DESC) R FROM EMP) WHERE R=2;

from sys import exit
exit()

As a parameter you can pass an exit code, which will be returned to OS. Default is 0.

printf is a fair bit more complicated than that. You have to supply a format string, and then the variables to apply to the format string. If you just supply one variable, C will assume that is the format string and try to print out all the bytes it finds in it until it hits a terminating nul (0x0).

So if you just give it an integer, it will merrily march through memory at the location your integer is stored, dumping whatever garbage is there to the screen, until it happens to come across a byte containing 0.

For a Java programmer, I'd imagine this is a rather rude introduction to C's lack of type checking. Believe me, this is only the tip of the iceberg. This is why, while I applaud your desire to expand your horizons by learning C, I highly suggest you do whatever you can to avoid writing real programs in it.

(This goes for everyone else reading this too.)

In Java 8 or Kotlin, I use Duration.ofNanos(1_000_000_000) like

val duration = Duration.ofNanos(1_000_000_000)
logger.info(String.format("%d %02dm %02ds %03d",
                elapse, duration.toMinutes(), duration.toSeconds(), duration.toMillis()))

Buttons with the btn class do not have underlines unless you are doing something wrong: In this case nesting <button> inside of <a>^†.

Something that I think you might be trying to do, is to create a bootstrap button without any decorations (underline, outline, button borders, etc). In other words, if your anchor is not a hyperlink, it is semantically a button.

Bootstrap's existing btn class appears to be the correct way to remove underline decorations from anchor buttons:

Use the button classes on an <a>, <button>, or <input> element

EDIT: Hitesh points out that btn will give you a shadow on :active. Thanks! I have modified my first example to use btn-link and incorporated the accepted answer's text-decoration: none to avoid this problem. Note that nesting a button inside of an anchor remains malformed html^†, a point which isn't addressed by any of the other answers.

<link href="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/3.3.5/css/bootstrap.css" rel="stylesheet"/>_x000D_
<div>_x000D_
    <!-- use anchors for borderless buttons -->_x000D_
    <a href="#" class="btn btn-link" style="text-decoration: none">Text</a> _x000D_
    <a href="#" class="btn btn-link" style="text-decoration: none">Text</a>_x000D_
</div>

Alternatively, for a regular button group using anchors:

<link href="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/3.3.5/css/bootstrap.css" rel="stylesheet"/>_x000D_
<div class="btn-group">_x000D_
    <!-- use anchors for borderless buttons -->_x000D_
    <a href="#" class="btn btn-default">Text</a> _x000D_
    <a href="#" class="btn btn-default">Text</a>_x000D_
</div>

In other words, it should not be necessary to introduce your own nounderline class and/or custom styling as the other answers suggest. However, be aware of certain subtleties.

^† According to the HTML5 spec, <a><button>..</button></a> is illegal:

Content model: Transparent, but there must be no interactive content descendant.

...

Interactive content is content that is specifically intended for user interaction. a, audio (if the controls attribute is present), button, embed, iframe, img (if the usemap attribute is present), input (if the type attribute is not in the hidden state), keygen, label, object (if the usemap attribute is present), select, textarea, video (if the controls attribute is present)

P.S. If, conversely, you wanted a button that has underline decorations, you might have used btn-link. However, that should be rare - this is almost always just an anchor instead of a button!

SELECT * FROM table
WHERE Dates IN (SELECT max(Dates) FROM table);

Here's the answer after a bit of research:

df.loc[:,'quantity'] *= -1 #seems to prevent SettingWithCopyWarning 

I think it can help you:

CREATE PROCEDURE DEPT_COUNT
(
    @DEPT_NAME VARCHAR(20), -- Input parameter
    @D_COUNT INT OUTPUT     -- Output parameter
    -- Remember parameters begin with "@"
)
AS -- You miss this word in your example
BEGIN
    SELECT COUNT(*) 
    INTO #D_COUNT -- Into a Temp Table (prefix "#")
    FROM INSTRUCTOR
    WHERE INSTRUCTOR.DEPT_NAME = DEPT_COUNT.DEPT_NAME
END

Then, you can call the SP like this way, for example:

DECLARE @COUNTER INT
EXEC DEPT_COUNT 'DeptName', @COUNTER OUTPUT
SELECT @COUNTER

Right. So I've finally got to the bottom of the problem: it was a botched in-place OTA upgrade.

My suspicions intensified after my Garmin Fenix 2 wasn't able to connect via bluetooth and after googling "Marshmallow upgrade issues". Anyway, a "Factory reset" fixed the issue.

Surprisingly, the reset did not return the phone to the original Kitkat; instead, the wipe process picked up the OTA downloaded 6.0 upgrade package and ran with it, resulting (I guess) in a "cleaner" upgrade.

Of course, this meant that the phone lost all the apps that I'd installed. But, freshly installed apps, including mine, work without any changes (i.e. there is backward compatibility). Whew!

What are you trying to accomplish?

You are 90% of the way there.

^[0-9,;]+$

Starting with the carat ^ indicates a beginning of line.

The [ indicates a character set

The 0-9 indicates characters 0 through 9, the comma , indicates comma, and the semicolon indicates a ;.

The closing ] indicates the end of the character set.

The plus + indicates that one or more of the "previous item" must be present. In this case it means that you must have one or more of the characters in the previously declared character set.

The dollar $ indicates the end of the line.

If your window rootViewController is UITabbarController(which is in most cases) then you can access tabbar in didFinishLaunchingWithOptions in the AppDelegate file.

func application(application: UIApplication!, didFinishLaunchingWithOptions launchOptions: NSDictionary!) -> Bool {
    // Override point for customization after application launch.

    if let tabBarController = self.window!.rootViewController as? UITabBarController {
        tabBarController.selectedIndex = 1
    }

    return true
}

This will open the tab with the index given (1) in selectedIndex.

If you do this in viewDidLoad of your firstViewController, you need to manage by flag or another way to keep track of the selected tab. The best place to do this in didFinishLaunchingWithOptions of your AppDelegate file or rootViewController custom class viewDidLoad.

This sets a JavaScript var for me directly from a web.config defined appSetting..

var pv = '@System.Web.Configuration.WebConfigurationManager.AppSettings["pv"]';

In WPF, you can now simply do:

Mouse.OverrideCursor = System.Windows.Input.Cursors.Wait; // set the cursor to loading spinner

Mouse.OverrideCursor = System.Windows.Input.Cursors.Arrow; // set the cursor back to arrow

Vector was part of 1.0 -- the original implementation had two drawbacks:

1. Naming: vectors are really just lists which can be accessed as arrays, so it should have been called ArrayList (which is the Java 1.2 Collections replacement for Vector).

2. Concurrency: All of the get(), set() methods are synchronized, so you can't have fine grained control over synchronization.

There is not much difference between ArrayList and Vector, but you should use ArrayList.

From the API doc.

As of the Java 2 platform v1.2, this class was retrofitted to implement the List interface, making it a member of the Java Collections Framework. Unlike the new collection implementations, Vector is synchronized.

I think every process you make start executing the line you create so something like this...

pid=fork() at line 6. fork function returns 2 values 
you have 2 pids, first pid=0 for child and pid>0 for parent 
so you can use if to separate

.

/*
    sleep(int time) to see clearly
    <0 fail 
    =0 child
    >0 parent
*/
int main(int argc, char** argv) {
    pid_t childpid1, childpid2;
    printf("pid = process identification\n");
    printf("ppid = parent process identification\n");
    childpid1 = fork();
    if (childpid1 == -1) {
        printf("Fork error !\n");

Things can get quite messy when you have a complicated view hierarchy, like having multiple navigation controllers and/or tab view controllers.

This implementation puts it on the individual view controllers to set when they would like to lock orientations, instead of relying on the App Delegate to find them by iterating through subviews.

Swift 3, 4, 5

In AppDelegate:

/// set orientations you want to be allowed in this property by default
var orientationLock = UIInterfaceOrientationMask.all

func application(_ application: UIApplication, supportedInterfaceOrientationsFor window: UIWindow?) -> UIInterfaceOrientationMask {
        return self.orientationLock
}

In some other global struct or helper class, here I created AppUtility:

struct AppUtility {

    static func lockOrientation(_ orientation: UIInterfaceOrientationMask) {
    
        if let delegate = UIApplication.shared.delegate as? AppDelegate {
            delegate.orientationLock = orientation
        }
    }

    /// OPTIONAL Added method to adjust lock and rotate to the desired orientation
    static func lockOrientation(_ orientation: UIInterfaceOrientationMask, andRotateTo rotateOrientation:UIInterfaceOrientation) {
   
        self.lockOrientation(orientation)
    
        UIDevice.current.setValue(rotateOrientation.rawValue, forKey: "orientation")
        UINavigationController.attemptRotationToDeviceOrientation()
    }

}

Then in the desired ViewController you want to lock orientations:

 override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)
    
    AppUtility.lockOrientation(.portrait)
    // Or to rotate and lock
    // AppUtility.lockOrientation(.portrait, andRotateTo: .portrait)
    
}

override func viewWillDisappear(_ animated: Bool) {
    super.viewWillDisappear(animated)
    
    // Don't forget to reset when view is being removed
    AppUtility.lockOrientation(.all)
}

If iPad or Universal App

Make sure that "Requires full screen" is checked in Target Settings -> General -> Deployment Info. supportedInterfaceOrientationsFor delegate will not get called if that is not checked.

Distinguishing contexts by setting the default schema

In EF6 you can have multiple contexts, just specify the name for the default database schema in the OnModelCreating method of you DbContext derived class (where the Fluent-API configuration is). This will work in EF6:

public partial class CustomerModel : DbContext
{   
    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        modelBuilder.HasDefaultSchema("Customer");

        // Fluent API configuration
    }   
}

This example will use "Customer" as prefix for your database tables (instead of "dbo"). More importantly it will also prefix the __MigrationHistory table(s), e.g. Customer.__MigrationHistory. So you can have more than one __MigrationHistory table in a single database, one for each context. So the changes you make for one context will not mess with the other.

When adding the migration, specify the fully qualified name of your configuration class (derived from DbMigrationsConfiguration) as parameter in the add-migration command:

add-migration NAME_OF_MIGRATION -ConfigurationTypeName FULLY_QUALIFIED_NAME_OF_CONFIGURATION_CLASS

A short word on the context key

According to this MSDN article "Chapter - Multiple Models Targeting the Same Database" EF 6 would probably handle the situation even if only one MigrationHistory table existed, because in the table there is a ContextKey column to distinguish the migrations.

However I prefer having more than one MigrationHistory table by specifying the default schema like explained above.

Using separate migration folders

In such a scenario you might also want to work with different "Migration" folders in you project. You can set up your DbMigrationsConfiguration derived class accordingly using the MigrationsDirectory property:

internal sealed class ConfigurationA : DbMigrationsConfiguration<ModelA>
{
    public ConfigurationA()
    {
        AutomaticMigrationsEnabled = false;
        MigrationsDirectory = @"Migrations\ModelA";
    }
}

internal sealed class ConfigurationB : DbMigrationsConfiguration<ModelB>
{
    public ConfigurationB()
    {
        AutomaticMigrationsEnabled = false;
        MigrationsDirectory = @"Migrations\ModelB";
    }
}

Summary

All in all, you can say that everything is cleanly separated: Contexts, Migration folders in the project and tables in the database.

I would choose such a solution, if there are groups of entities which are part of a bigger topic, but are not related (via foreign keys) to one another.

If the groups of entities do not have anything to do which each other, I would created a separate database for each of them and also access them in different projects, probably with one single context in each project.

If there are multiple levels of inheritance, you can specify the direct base class, even if the actual implementation is at a lower level.

class Foo
{
public:
  virtual void DoStuff ()
  {
  }
};

class Bar : public Foo
{
};

class Baz : public Bar
{
public:
  void DoStuff ()
  {
    Bar::DoStuff() ;
  }
};

In this example, the class Baz specifies Bar::DoStuff() although the class Bar does not contain an implementation of DoStuff. That is a detail, which Baz does not need to know.

It is clearly a better practice to call Bar::DoStuff than Foo::DoStuff, in case a later version of Bar also overrides this method.

or alternatively you could not bother coding for it and use the 'conditional formatting' function in Excel which will set the background colour and font colour based on cell value.

There are only two variables here so set the default to yellow and then overwrite when the value is greater than or less than your threshold values.

Before document/window ready add "extend" to jQuery :

$.extend(
{
    redirectPost: function(location, args)
    {
        var form = '';
        $.each( args, function( key, value ) {

            form += '<input type="hidden" name="'+value.name+'" value="'+value.value+'">';
            form += '<input type="hidden" name="'+key+'" value="'+value.value+'">';
        });
        $('<form action="'+location+'" method="POST">'+form+'</form>').submit();
    }
});

Use :

$.redirectPost("someurl.com", $("#SomeForm").serializeArray());

Note : this method cant post files .

You can do this with SQL Server Management Studio.

? Right click the table design and go to Relationships and choose the foreign key on the left-side pane and in the right-side pane, expand the menu "INSERT and UPDATE specification" and select "Cascade" as Delete Rule.

Real life example:

public class Control {
    public static final long EXPIRED_ON = 1386082988202l;
    public static final boolean isExpired() {
        return (System.currentTimeMillis() > EXPIRED_ON);
    }
}

Then in other classes, I can exit if the code has expired. If I reference the EXPIRED_ON variable from another class, the constant is inline to the byte code, making it very hard to track down all places in the code that checks the expiry date. However, if the other classes invoke the isExpired() method, the actual method is called, meaning a hacker could replace the isExpired method with another which always returns false.

I agree it would be very nice to force a compiler to inline the static final method to all classes which reference it. In that case, you need not even include the Control class, as it would not be needed at runtime.

From my research, this cannot be done. Perhaps some Obfuscator tools can do this, or, you could modify your build process to edit sources before compile.

As for proving if the method from the control class is placed inline to another class during compile, try running the other class without the Control class in the classpath.

The only thing that springs to mind for this is to use a proxy server based in Europe. Either have your colleague set one up [if possible] or find a free proxy. A quick Google search came up with http://www.anonymousinet.com/ as the top result.

I'd recommend using the Buffer class:

var someEncodedString = Buffer.from('someString', 'utf-8');

This avoids any unnecessary dependencies that other answers require, since Buffer is included with node.js, and is already defined in the global scope.

All you need is a <clear /> tag. Here's an example:

<configuration>
  <system.webServer>
    <defaultDocument>
      <files>
        <clear />
        <add value="default.aspx" />
      </files>
    </defaultDocument>
  </system.webServer>
</configuration>

I just installed Oracle Instant Client 18_3 with the SDK. The PATH and ENV variable is set as instructed on the install page but I get the OCl.dll not found error. I searched the entire drive recursively and no such DLL exists.

So now what?

With the install instructions (not updated for 18_3) and downloads there are MISTAKES at step 13, so watch out for that.

When you create the folder structure for the downloads just write them the old way "c:\oraclient". Then when you unzip the basic, SDK and instant Client install for Windows 10_x64 extract them to "C:\oraclient\", because they all write to the same default folder. Then, when you set the ENV variable (which is no longer ORACLE_HOME, but now is OCI_LIB64) and the PATH, you will point to "C:\oraclient\instantclient_18_3".

To be sure you got it all right drill down and look for any duplicate "instantclient_18_3" folders. If you do have those cut and paste the CONTENTS to the root folder "C:\oraclient\instantclient_18_3\" folder.

Whoever works on the documentation at Oracle needs to troubleshoot better. I've seen "C:\oreclient_dir_install", "c:\oracle", "c:\oreclient" and "c:\oraclient" all mentioned as install directories, all for Windows x64 installs

BTW, install the C++ redist it helps. The 18.3 Basic package requires the Microsoft Visual Studio 2013 Redistributable.

The map() function is a best choice for this case

tl;dr - Do this:

const newArr = [
  {name: 'eve'},
  {name: 'john'},
  {name: 'jane'}
].map(v => ({...v, isActive: true}))

The map() function won't modify the initial array, but creates a new one. This is also a good practice to keep initial array unmodified.

Alternatives:

const initialArr = [
      {name: 'eve'},
      {name: 'john'},
      {name: 'jane'}
    ]

const newArr1 = initialArr.map(v => ({...v, isActive: true}))
const newArr2 = initialArr.map(v => Object.assign(v, {isActive: true}))

// Results of newArr1 and newArr2 are the same

Add a key value pair conditionally

const arr = [{value: 1}, {value: 1}, {value: 2}]   
const newArr1 = arr.map(v => ({...v, isActive: v.value > 1}))

What if I don't want to add new field at all if the condition is false?

const arr = [{value: 1}, {value: 1}, {value: 2}]   
const newArr = arr.map(v => {
  return v.value > 1 ? {...v, isActive: true} : v 
})

Adding WITH modification of the initial array

const initialArr = [{a: 1}, {b: 2}]
initialArr.forEach(v => {v.isActive = true;});

This is probably not a best idea, but in a real life sometimes it's the only way.

Questions

• Should I use a spread operator(...), or Object.assign and what's the difference?

Personally I prefer to use spread operator, because I think it uses much wider in modern web community (especially react's developers love it). But you can check the difference yourself: link(a bit opinionated and old, but still)

• Can I use function keyword instead of =>?

Sure you can. The fat arrow (=>) functions play a bit different with this, but it's not so important for this particular case. But fat arrows function shorter and sometimes plays better as a callbacks. Therefore the usage of fat arrow functions is more modern approach.

• What Actually happens inside map function: .map(v => ({...v, isActive: true})?

Map function iterates by array's elements and apply callback function for each of them. That callback function should return something that will become an element of a new array. We tell to the .map() function following: take current value(v which is an object), take all key-value pairs away from v andput it inside a new object({...v}), but also add property isActive and set it to true ({...v, isActive: true}) and then return the result. Btw, if original object contains isActive filed it will be overwritten. Object.assign works in a similar way.

• Can I add more then one field at a time

Yes.

[{value: 1}, {value: 1}, {value: 2}].map(v => ({...v, isActive: true, howAreYou: 'good'}))

• What I should not do inside .map() method

You shouldn't do any side effects[link 1, link 2], but apparently you can.

Also be noticed that map() iterates over each element of the array and apply function for each of them. So if you do some heavy stuff inside, you might be slow. This (a bit hacky) solution might be more productive in some cases (but I don't think you should apply it more then once in a lifetime).

• Can I extract map's callback to a separate function?

Sure you can.

const arr = [{value: 1}, {value: 1}, {value: 2}]   
const newArr = arr.map(addIsActive)

function addIsActive(v) {
    return {...v, isActive: true}
}

• What's wrong with old good for loop?

Nothing is wrong with for, you can still use it, it's just an old-school approach which is more verbose, less safe and mutate the initial array. But you can try:

const arr = [{a: 1}, {b: 2}]
for (let i = 0; i < arr.length; i++) {
 arr[i].isActive = true
}

• What also i should learn

It would be smart to learn well following methods map(), filter(), reduce(), forEach(), and find(). These methods can solve 80% of what you usually want to do with arrays.

the following deals with namespaces. In this case, you construct the wrapper to include the namespace definitions, and pass it into the function. use a colon to identify the namespace.

Test Array

$inarray = [];
$inarray['p:apple'] = "red";
$inarray['p:pear'] = "green";
$inarray['p:peach'] = "orange";
$inarray['p1:grocers'] = ['p1:local' => "cheap", 'p1:imported' => "expensive"];


$xml = new SimpleXMLElement( '<p:wrapper xmlns:p="http://namespace.org/api" xmlns:p1="http://namespace.org/api2 /> ');

array_to_xml($xml,$inarray); 




function array_to_xml(SimpleXMLElement $object, array $data)
{   
    $nslist = $object->getDocNamespaces();

    foreach ($data as $key => $value)
    {   
        $nspace = null;
        $keyparts = explode(":",$key,2);
        if ( count($keyparts)==2) 
            $nspace = $nslist[$keyparts[0]];

        if (is_array($value))
        {   
            $key = is_numeric($key) ? "item$key" : $key;
            $new_object = $object->addChild($key,null,$nspace);
            array_to_xml($new_object, $value);
        }   
        else
        {   
            $key = is_numeric($key) ? "item$key" : $key;
            $object->addChild($key, $value,$nspace);
        }   
    }   
}   

Try this:

apt-get install lib32stdc++6

In some situations, it could be desirable to ensure the Unique key does not exists before create it. In such cases, the script below might help:

IF Exists(SELECT * FROM sys.indexes WHERE name Like '<index_name>')
    ALTER TABLE dbo.<target_table_name> DROP CONSTRAINT <index_name> 
GO

ALTER TABLE dbo.<target_table_name> ADD CONSTRAINT <index_name> UNIQUE NONCLUSTERED (<col_1>, <col_2>, ..., <col_n>) 
GO

This is how I converted a number to an ASCII code. 0 though 9 in hex code is 0x30-0x39. 6 would be 0x36.

unsigned int temp = 6;
or you can use unsigned char temp = 6;
unsigned char num;
 num = 0x30| temp;

this will give you the ASCII value for 6. You do the same for 0 - 9

to convert ASCII to a numeric value I came up with this code.

unsigned char num,code;
code = 0x39; // ASCII Code for 9 in Hex
num = 0&0F & code;

Your DemoApplication class is in the com.ag.digital.demo.boot package and your LoginBean class is in the com.ag.digital.demo.bean package. By default components (classes annotated with @Component) are found if they are in the same package or a sub-package of your main application class DemoApplication. This means that LoginBean isn't being found so dependency injection fails.

There are a couple of ways to solve your problem:

1. Move LoginBean into com.ag.digital.demo.boot or a sub-package.
2. Configure the packages that are scanned for components using the scanBasePackages attribute of @SpringBootApplication that should be on DemoApplication.

A few of other things that aren't causing a problem, but are not quite right with the code you've posted:

• @Service is a specialisation of @Component so you don't need both on LoginBean
• Similarly, @RestController is a specialisation of @Component so you don't need both on DemoRestController
• DemoRestController is an unusual place for @EnableAutoConfiguration. That annotation is typically found on your main application class (DemoApplication) either directly or via @SpringBootApplication which is a combination of @ComponentScan, @Configuration, and @EnableAutoConfiguration.

If there are multiple columns with identical names, the solutions given here so far will remove all of the columns, which may not be what one is looking for. This may be the case if one is trying to remove duplicate columns except one instance. The example below clarifies this situation:

# make a df with duplicate columns 'x'
df = pd.DataFrame({'x': range(5) , 'x':range(5), 'y':range(6, 11)}, columns = ['x', 'x', 'y']) 


df
Out[495]: 
   x  x   y
0  0  0   6
1  1  1   7
2  2  2   8
3  3  3   9
4  4  4  10

# attempting to drop the first column according to the solution offered so far     
df.drop(df.columns[0], axis = 1) 
   y
0  6
1  7
2  8
3  9
4  10

As you can see, both Xs columns were dropped. Alternative solution:

column_numbers = [x for x in range(df.shape[1])]  # list of columns' integer indices

column_numbers .remove(0) #removing column integer index 0
df.iloc[:, column_numbers] #return all columns except the 0th column

   x  y
0  0  6
1  1  7
2  2  8
3  3  9
4  4  10

As you can see, this truly removed only the 0th column (first 'x').

According to Documentation

git diff Shows changes between the working tree and the index or a tree, changes between the index and a tree, changes between two trees, changes resulting from a merge, changes between two blob objects, or changes between two files on disk.

In git diff - There's a significant difference between two dots .. and 3 dots ... in the way we compare branches or pull requests in our repository. I'll give you an easy example which demonstrates it easily.

Example: Let's assume we're checking out new branch from master and pushing some code in.

  G---H---I feature (Branch)
 /
A---B---C---D master (Branch)

• Two dots - If we want to show the diffs between all changes happened in the current time on both sides, We would use the git diff origin/master..feature or just git diff origin/master
  ,output: ( H, I against A, B, C, D )

• Three dots - If we want to show the diffs between the last common ancestor (A), aka the check point we started our new branch ,we use git diff origin/master...feature,output: (H, I against A ).

• I'd rather use the 3 dots in most circumstances.

The below one had worked for me

webDriver.findElement(By.xpath("//input[@type='file' and @name='importFile']")).sendKeys("C:/path/to/file.jpg");

It can be checked via:

        var httpException = ex as HttpException;
        if (httpException != null)
        {
            if (httpException.WebEventCode == System.Web.Management.WebEventCodes.RuntimeErrorPostTooLarge)
            {
                // Request too large

                return;

            }
        }

Try something like this:

SELECT 
* 
FROM
(SELECT ks, COUNT(*) AS '# Tasks' FROM Table GROUP BY ks) t1 
INNER JOIN
(SELECT ks, COUNT(*) AS '# Late' FROM Table WHERE Age > Palt GROUP BY ks) t2
ON t1.ks = t2.ks

It depends upon which platform you're on as to how it will be translated and whether it will be there at all: Wikipedia entry on newline

Use the title attribute, for example:

<div title="them's hoverin' words">hover me</div>

or:

For those who are learning node/express (just like me): do not use wildcard routing if possible!

I also wanted to implement the routing for GET /users/:id/whatever using wildcard routing. This is how I got here.

More info: https://blog.praveen.science/wildcard-routing-is-an-anti-pattern/

This is because findViewById() searches in the activity_main layout, while the button is located in the fragment's layout fragment_main.

Move that piece of code in the onCreateView() method of the fragment:

//...

View rootView = inflater.inflate(R.layout.fragment_main, container, false);
Button buttonClick = (Button)rootView.findViewById(R.id.button);
buttonClick.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        onButtonClick((Button) view);
    }
});

Notice that now you access it through rootView view:

Button buttonClick = (Button)rootView.findViewById(R.id.button);

otherwise you would get again NullPointerException.

If you use bash, then the terminal history is saved in a file called .bash_history. Delete it, and history will be gone.

However, for MySQL the better approach is not to enter the password in the command line. If you just specify the -p option, without a value, then you will be prompted for the password and it won't be logged.

Another option, if you don't want to enter your password every time, is to store it in a my.cnf file. Create a file named ~/.my.cnf with something like:

[client]
user = <username>
password = <password>

Make sure to change the file permissions so that only you can read the file.

Of course, this way your password is still saved in a plaintext file in your home directory, just like it was previously saved in .bash_history.

you simple type:

timestamps.sort()
timestamps=timestamps[::-1]

If you have Adobe Reader installed, then you should be able to just set it as the default printer. And VOILA! You can print to PDF!

XMLStarlet or another XPath engine is the correct tool for this job.

For instance, with data.xml containing the following:

<root>
  <item> 
    <title>15:54:57 - George:</title>
    <description>Diane DeConn? You saw Diane DeConn!</description> 
  </item> 
  <item> 
    <title>15:55:17 - Jerry:</title> 
    <description>Something huh?</description>
  </item>
</root>

...you can extract only the first title with the following:

xmlstarlet sel -t -m '//title[1]' -v . -n <data.xml

Trying to use sed for this job is troublesome. For instance, the regex-based approaches won't work if the title has attributes; won't handle CDATA sections; won't correctly recognize namespace mappings; can't determine whether a portion of the XML documented is commented out; won't unescape attribute references (such as changing Brewster & Jobs to Brewster & Jobs), and so forth.

It is possible to parse Markdown in Lua using the Lunamark code (see its Github repo), meaning that Markdown may be parsed directly by macros in Luatex and supports conversion to many of the formats supported by Pandoc (i.e., the library is well-suited to use in lualatex, context, Metafun, Plain Luatex, and texlua scripts).

The project was started by John MacFarlane, author of Pandoc, and the tool's development tracks that of Pandoc quite closely and is of similar (i.e., excellent) quality.

Khaled Hosny wrote a Context module, providing convenient macro support. Michal's answer to the Is there any package with Markdown support? question gives code providing similar support for Latex.

The most important part is the concepts. Once you understand how the building blocks work, differences in syntax amount to little more than mild dialects. A layer on top of your regular expression engine's syntax is the syntax of the programming language you're using. Languages such as Perl remove most of this complication, but you'll have to keep in mind other considerations if you're using regular expressions in a C program.

If you think of regular expressions as building blocks that you can mix and match as you please, it helps you learn how to write and debug your own patterns but also how to understand patterns written by others.

Start simple

Conceptually, the simplest regular expressions are literal characters. The pattern N matches the character 'N'.

Regular expressions next to each other match sequences. For example, the pattern Nick matches the sequence 'N' followed by 'i' followed by 'c' followed by 'k'.

If you've ever used grep on Unix—even if only to search for ordinary looking strings—you've already been using regular expressions! (The re in grep refers to regular expressions.)

Order from the menu

Adding just a little complexity, you can match either 'Nick' or 'nick' with the pattern [Nn]ick. The part in square brackets is a character class, which means it matches exactly one of the enclosed characters. You can also use ranges in character classes, so [a-c] matches either 'a' or 'b' or 'c'.

The pattern . is special: rather than matching a literal dot only, it matches any character^†. It's the same conceptually as the really big character class [-.?+%$A-Za-z0-9...].

Think of character classes as menus: pick just one.

Helpful shortcuts

Using . can save you lots of typing, and there are other shortcuts for common patterns. Say you want to match a digit: one way to write that is [0-9]. Digits are a frequent match target, so you could instead use the shortcut \d. Others are \s (whitespace) and \w (word characters: alphanumerics or underscore).

The uppercased variants are their complements, so \S matches any non-whitespace character, for example.

Once is not enough

From there, you can repeat parts of your pattern with quantifiers. For example, the pattern ab?c matches 'abc' or 'ac' because the ? quantifier makes the subpattern it modifies optional. Other quantifiers are

• * (zero or more times)
• + (one or more times)
• {n} (exactly n times)
• {n,} (at least n times)
• {n,m} (at least n times but no more than m times)

Putting some of these blocks together, the pattern [Nn]*ick matches all of

• ick
• Nick
• nick
• Nnick
• nNick
• nnick
• (and so on)

The first match demonstrates an important lesson: * always succeeds! Any pattern can match zero times.

A few other useful examples:

• [0-9]+ (and its equivalent \d+) matches any non-negative integer
• \d{4}-\d{2}-\d{2} matches dates formatted like 2019-01-01

Grouping

A quantifier modifies the pattern to its immediate left. You might expect 0abc+0 to match '0abc0', '0abcabc0', and so forth, but the pattern immediately to the left of the plus quantifier is c. This means 0abc+0 matches '0abc0', '0abcc0', '0abccc0', and so on.

To match one or more sequences of 'abc' with zeros on the ends, use 0(abc)+0. The parentheses denote a subpattern that can be quantified as a unit. It's also common for regular expression engines to save or "capture" the portion of the input text that matches a parenthesized group. Extracting bits this way is much more flexible and less error-prone than counting indices and substr.

Alternation

Earlier, we saw one way to match either 'Nick' or 'nick'. Another is with alternation as in Nick|nick. Remember that alternation includes everything to its left and everything to its right. Use grouping parentheses to limit the scope of |, e.g., (Nick|nick).

For another example, you could equivalently write [a-c] as a|b|c, but this is likely to be suboptimal because many implementations assume alternatives will have lengths greater than 1.

Escaping

Although some characters match themselves, others have special meanings. The pattern \d+ doesn't match backslash followed by lowercase D followed by a plus sign: to get that, we'd use \\d\+. A backslash removes the special meaning from the following character.

Greediness

Regular expression quantifiers are greedy. This means they match as much text as they possibly can while allowing the entire pattern to match successfully.

For example, say the input is

"Hello," she said, "How are you?"

You might expect ".+" to match only 'Hello,' and will then be surprised when you see that it matched from 'Hello' all the way through 'you?'.

To switch from greedy to what you might think of as cautious, add an extra ? to the quantifier. Now you understand how \((.+?)\), the example from your question works. It matches the sequence of a literal left-parenthesis, followed by one or more characters, and terminated by a right-parenthesis.

If your input is '(123) (456)', then the first capture will be '123'. Non-greedy quantifiers want to allow the rest of the pattern to start matching as soon as possible.

(As to your confusion, I don't know of any regular-expression dialect where ((.+?)) would do the same thing. I suspect something got lost in transmission somewhere along the way.)

Anchors

Use the special pattern ^ to match only at the beginning of your input and $ to match only at the end. Making "bookends" with your patterns where you say, "I know what's at the front and back, but give me everything between" is a useful technique.

Say you want to match comments of the form

-- This is a comment --

you'd write ^--\s+(.+)\s+--$.

Build your own

Regular expressions are recursive, so now that you understand these basic rules, you can combine them however you like.

Footnote

†: The statement above that . matches any character is a simplification for pedagogical purposes that is not strictly true. Dot matches any character except newline, "\n", but in practice you rarely expect a pattern such as .+ to cross a newline boundary. Perl regexes have a /s switch and Java Pattern.DOTALL, for example, to make . match any character at all. For languages that don't have such a feature, you can use something like [\s\S] to match "any whitespace or any non-whitespace", in other words anything.

You cannot "convert" an existing column into an IDENTITY column - you will have to create a new column as INT IDENTITY:

ALTER TABLE ProductInProduct 
ADD NewId INT IDENTITY (1, 1);

Update:

OK, so there is a way of converting an existing column to IDENTITY. If you absolutely need this - check out this response by Martin Smith with all the gory details.

This is considered as features in Gitlab.

If using Spring MVC, the Spring Expression Language (SpEL) can be helpful:

<spring:eval expression="dp.status == T(com.example.Status).VALID" var="isValid" />
<c:if test="${isValid}">
   isValid
</c:if>

The following simple code worked for me.

[imageView setContentMode:UIViewContentModeScaleAspectFill];
[imageView setClipsToBounds:YES];

I found an answer here well practiced, but it was still necessary to add a delay

Create the following directive:

angular.module('MyApp').directive('emitLastRepeaterElement', function() {
return function(scope) {
    if (scope.$last){
        scope.$emit('LastRepeaterElement');
    }
}; });

Add it to your repeater as an attribute, like this:

<div ng-repeat="item in items" emit-last-repeater-element></div>

According to Radu,:

$scope.eventoSelecionado.internamento_evolucoes.forEach(ie => {mycode});

For me it works, but I still need to add a setTimeout

$scope.eventoSelecionado.internamento_evolucoes.forEach(ie => {
setTimeout(function() { 
    mycode
}, 100); });

You can use local redirect. Following codes are jumping the HomeController's Index page:

public class SharedController : Controller
    {
        // GET: /<controller>/
        public IActionResult _Layout(string btnLogout)
        {
            if (btnLogout != null)
            {
                return LocalRedirect("~/Index");
            }

            return View();
        }
}

Bergi's suggested function is really nice:

var promiseWhile = Promise.method(function(condition, action) {
      if (!condition()) return;
    return action().then(promiseWhile.bind(null, condition, action));
});

Still I want to make a tiny addition, which makes sense, when using promises:

var promiseWhile = Promise.method(function(condition, action, lastValue) {
  if (!condition()) return lastValue;
  return action().then(promiseWhile.bind(null, condition, action));
});

This way the while loop can be embedded into a promise chain and resolves with lastValue (also if the action() is never run). See example:

var count = 10;
util.promiseWhile(
  function condition() {
    return count > 0;
  },
  function action() {
    return new Promise(function(resolve, reject) {
      count = count - 1;
      resolve(count)
    })
  },
  count)

Swift 3+ one liner to sum properties of objects

var totalSum = scaleData.map({$0.points}).reduce(0, +)

Where points is the property in my custom object scaleData that I am trying to reduce

You can use json.loads:

import json
import requests

response = requests.get(...)
json_data = json.loads(response.text)

This converts a given string into a dictionary which allows you to access your JSON data easily within your code.

Or you can use @Martijn's helpful suggestion, and the higher voted answer, response.json().

It's possible that you've run out of memory or some space elsewhere and it prompted the system to mount an overflow filesystem, and for whatever reason, it's not going away.

Try unmounting the overflow partition:

umount /tmp

or

umount overflow

You could also use the the basic structure for the PL/pgSQL CASE with anonymous code block procedure block:

DO $$ BEGIN
    CASE
        WHEN boolean-expression THEN
          statements;
        WHEN boolean-expression THEN
          statements;
        ...
        ELSE
          statements;
    END CASE;

This issue might be helpful for you, it explains how to achieve TPUStrategy, a popular functionality of tf.contrib in TF<2.0.

So, in TF 1.X you could do the following:

resolver = tf.contrib.cluster_resolver.TPUClusterResolver('grpc://' + os.environ['COLAB_TPU_ADDR'])
tf.contrib.distribute.initialize_tpu_system(resolver)
strategy = tf.contrib.distribute.TPUStrategy(resolver)

And in TF>2.0, where tf.contrib is deprecated, you achieve the same by:

tf.config.experimental_connect_to_host('grpc://' + os.environ['COLAB_TPU_ADDR'])
resolver = tf.distribute.cluster_resolver.TPUClusterResolver('grpc://' + os.environ['COLAB_TPU_ADDR'])
tf.tpu.experimental.initialize_tpu_system(resolver)
strategy = tf.distribute.experimental.TPUStrategy(resolver) 

Do you mean this one?

$('.update-cart').click(function(e) {
    updateCartWidget();
    e.stopPropagation();
    e.preventDefault();
});

$('.update-cart').click(function() {
    updateCartWidget();
    return false;
});

The following methods achieve the exact same thing.

If you want to use array without knowing the size first you have to declare it and later you can instantiate it like

string[] myArray;
...
...
myArray=new string[someItems.count];

You want an outer join for this (and you need to use person as the "driving" table)

SELECT person.person_id, COUNT(appointment.person_id) AS "number_of_appointments"
FROM person 
  LEFT JOIN appointment ON person.person_id = appointment.person_id
GROUP BY person.person_id;

The reason why this is working, is that the outer (left) join will return NULL for those persons that do not have an appointment. The aggregate function count() will not count NULL values and thus you'll get a zero.

If you want to learn more about outer joins, here is a nice tutorial: http://sqlzoo.net/wiki/Using_Null

For example using property styles for custom container

const DriverSelector = props => {
  const Container = props.container;
  const otherProps = {
    ...( props.containerStyles && { style: props.containerStyles } )
  };

  return (
    <Container {...otherProps} >

There is a way of doing this with tags, which allows for multiple defaults.

Assume you have the following struct, with 2 default tags default0 and default1.

type A struct {
   I int    `default0:"3" default1:"42"`
   S string `default0:"Some String..." default1:"Some Other String..."`
}

Now it's possible to Set the defaults.

func main() {

ptr := &A{}

Set(ptr, "default0")
fmt.Printf("ptr.I=%d ptr.S=%s\n", ptr.I, ptr.S)
// ptr.I=3 ptr.S=Some String...

Set(ptr, "default1")
fmt.Printf("ptr.I=%d ptr.S=%s\n", ptr.I, ptr.S)
// ptr.I=42 ptr.S=Some Other String...
}

Here's the complete program in a playground.

If you're interested in a more complex example, say with slices and maps, then, take a look at creasty/defaultse

min_element and max_element return iterators, not values. So you need *min_element... and *max_element....

All the answers above couldn't solve the problem in my case. My ImageView was placed in a customized UITableViewCell. Therefore I had also call the layoutIfNeeded() method from here. Example:

 class NameTableViewCell:UITableViewCell,UITextFieldDelegate { ...

 override func awakeFromNib() {

    self.layoutIfNeeded()
    profileImageView.layoutIfNeeded()

    profileImageView.isUserInteractionEnabled = true
    let square = profileImageView.frame.size.width < profileImageView.frame.height ? CGSize(width: profileImageView.frame.size.width, height: profileImageView.frame.size.width) : CGSize(width: profileImageView.frame.size.height, height:  profileImageView.frame.size.height)
    profileImageView.addGestureRecognizer(tapGesture)
    profileImageView.layer.cornerRadius = square.width/2
    profileImageView.clipsToBounds = true;
}

Instead of gdb, run gdbtui. Or run gdb with the -tui switch. Or press C-x C-a after entering gdb. Now you're in GDB's TUI mode.

Enter layout asm to make the upper window display assembly -- this will automatically follow your instruction pointer, although you can also change frames or scroll around while debugging. Press C-x s to enter SingleKey mode, where run continue up down finish etc. are abbreviated to a single key, allowing you to walk through your program very quickly.

You can use Jquery's on method and listen for the scroll event.

What you have is a parse error. Those are thrown before any code is executed. A PHP file needs to be parsed in its entirety before any code in it can be executed. If there's a parse error in the file where you're setting your error levels, they won't have taken effect by the time the error is thrown.

Either break your files up into smaller parts, like setting the error levels in one file and then includeing another file which contains the actual code (and errors), or set the error levels outside PHP using php.ini or .htaccess directives.

The primary flag seems to only work for vagrant ssh for me.

In the past I have used the following method to hack around the issue.

# stage box intended for configuration closely matching production if ARGV[1] == 'stage'     config.vm.define "stage" do |stage|         box_setup stage, \         "10.9.8.31", "deploy/playbook_full_stack.yml", "deploy/hosts/vagrant_stage.yml"     end end 

These are escape characters which are used to manipulate string.

\t  Insert a tab in the text at this point.
\b  Insert a backspace in the text at this point.
\n  Insert a newline in the text at this point.
\r  Insert a carriage return in the text at this point.
\f  Insert a form feed in the text at this point.
\'  Insert a single quote character in the text at this point.
\"  Insert a double quote character in the text at this point.
\\  Insert a backslash character in the text at this point.

The easiest way in your case (horizontal line) is to add a subview with black background color and frame [0, 200, 320, 1].

Code sample (I hope there are no errors - I wrote it without Xcode):

UIView *lineView = [[UIView alloc] initWithFrame:CGRectMake(0, 200, self.view.bounds.size.width, 1)];
lineView.backgroundColor = [UIColor blackColor];
[self.view addSubview:lineView];
[lineView release];
// You might also keep a reference to this view 
// if you are about to change its coordinates.
// Just create a member and a property for this...

Another way is to create a class that will draw a line in its drawRect method (you can see my code sample for this here).

In javascript there are trues and truthys. When something is true it is obviously true or false. When something is truthy it may or may not be a boolean, but the "cast" value of is a boolean.

Examples.

true == true; // (true) true
1 == true; // (true) truthy
"hello" == true;  // (true) truthy
[1, 2, 3] == true; // (true) truthy
[] == false; // (true) truthy
false == false; // (true) true
0 == false; // (true) truthy
"" == false; // (true) truthy
undefined == false; // (true) truthy
null == false; // (true) truthy

This can make things simpler if you want to check if a string is set or an array has any values.

var users = [];

if(users) {
  // this array is populated. do something with the array
}

var name = "";

if(!name) {
  // you forgot to enter your name!
}

And as stated. expect(something).toBe(true) and expect(something).toBeTrue() is the same. But expect(something).toBeTruthy() is not the same as either of those.

dicts=[
{"name": "Tom", "age": 10},
{"name": "Mark", "age": 5},
{"name": "Pam", "age": 7}
]

from collections import defaultdict
dicts_by_name=defaultdict(list)
for d in dicts:
    dicts_by_name[d['name']]=d

print dicts_by_name['Tom']

#output
#>>>
#{'age': 10, 'name': 'Tom'}

Just posting in case it help someone else. The cause of this error for me was a missing do after creating a form with form_with. Hope that may help someone else

My opinion of abstraction is not in the sense of hiding implementation or background details!

Abstraction gives us the benefit to deal with a representation of the real world which is easier to handle, has the ability to be reused, could be combined with other components of our more or less complex program package. So we have to find out how we pick a complete peace of the real world, which is complete enough to represent the sense of our algorithm and data. The implementation of the interface may hide the details but this is not part of the work we have to do for abstracting something.

For me most important thing for abstraction is:

1. reduction of complexity
2. reduction of size/quantity
3. splitting of non related domains to clear and independent components

All this has for me nothing to do with hiding background details!

If you think of sorting some data, abstraction can result in:

1. a sorting algorithm, which is independent of the data representation
2. a compare function, which is independent of data and sort algorithm
3. a generic data representation, which is independent of the used algorithms

All these has nothing to do with hiding information.

None of these answers mention the colClasses argument which is another way to specify the variable classes in read.csv.

 stuckey <- read.csv("C:/kalle/R/stuckey.csv", colClasses = "numeric") # all variables to numeric

or you can specify which columns to convert:

stuckey <- read.csv("C:/kalle/R/stuckey.csv", colClasses = c("PTS" = "numeric", "MP" = "numeric") # specific columns to numeric

Note that if a variable can't be converted to numeric then it will be converted to factor as default which makes it more difficult to convert to number. Therefore, it can be advisable just to read all variables in as 'character' colClasses = "character" and then convert the specific columns to numeric once the csv is read in:

stuckey <- read.csv("C:/kalle/R/stuckey.csv", colClasses = "character")
point <- as.numeric(stuckey$PTS)
time <- as.numeric(stuckey$MP)

One line command in Windows to get the IP Address.

for /F "tokens=14" %%i in ('"ipconfig | findstr IPv4"') do SET LOCAL_IP=%%i

After this command echo %LOCAL_IP% will print the ip address. Or you can use %LOCAL_IP% as reference variable in your batch script

Please note that since Spring Boot 1.3.0.M1, you are able to build fully executable jars using Maven and Gradle.

For Maven, just include the following in your pom.xml:

<plugin>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-maven-plugin</artifactId>
    <configuration>
        <executable>true</executable>
    </configuration>
</plugin>

For Gradle add the following snippet to your build.gradle:

springBoot {
    executable = true
}

The fully executable jar contains an extra script at the front of the file, which allows you to just symlink your Spring Boot jar to init.d or use a systemd script.

init.d example:

$ln -s /var/yourapp/yourapp.jar /etc/init.d/yourapp

This allows you to start, stop and restart your application like:

$/etc/init.d/yourapp start|stop|restart

Or use a systemd script:

[Unit]
Description=yourapp
After=syslog.target

[Service]
ExecStart=/var/yourapp/yourapp.jar
User=yourapp
WorkingDirectory=/var/yourapp
SuccessExitStatus=143

[Install]
WantedBy=multi-user.target

More information at the following links:

• Installation as an init.d service
• Installation as a systemd service

I don't think this would be possible to do across all browsers.

W3Schools reports that the option events exist in all browsers, but after setting up this test demo. I can only get it to work for Firefox (not Chrome or IE), I haven't tested it on other browsers.

Firefox also allows mouseenter and mouseleave but this is not reported on the w3schools page.

Update: Honestly, from looking at the example code you provided, I wouldn't even use a select box. I think it would look nicer with a slider. I've updated your demo. I had to make a few minor changes to your ratings object (adding a level number) and the safesurf tab. But I left pretty much everything else intact.

You can easily simulate a click on an element, but a click on a <select> won’t open up the dropdown.

Using multiple selects can be problematic. Perhaps you should consider radio buttons inside a container element which you can expand and contract as needed.

The only way to show or hide a component in react native is checking a value of a parameter of app state like state or props. I provided a complete example as below:

import React, {Component} from 'react';
import {View,Text,TextInput,TouchableHighlight} from 'react-native'

class App extends Component {

    constructor(props){
        super(props);
        this.state={
            show:false
        }
}

    showCancel=()=>{
        this.setState({show:true})
    };

    hideCancel=()=>{
        this.setState({show:false})
    };

    renderTouchableHighlight(){
        if(this.state.show){
           return(
               <TouchableHighlight
                   style={{borderColor:'black',borderWidth:1,marginTop:20}}
                   onPress={this.hideCancel}>
                   <View>
                       <Text>Cancel</Text>
                   </View>
               </TouchableHighlight>
           )
        }
        return null;
    }

    render() {


        return (
            <View style={{justifyContent:'center',alignItems:'center',flex:1}}>
                <TextInput
                    style={{borderColor:'black',borderBottomWidth:1}}
                    onFocus={this.showCancel}
                />
                {this.renderTouchableHighlight()}

            </View>
        );
    }
}

export default App;

Add new column and fill it with ascending numbers. Then filter by ([column] mod 7 = 0) or something like that (don't have Excel in front of me to actually try this);

If you can't filter by formula, add one more column and use the formula =MOD([column; 7]) in it then filter zeros and you'll get all seventh rows.

A complete solution in swift, in your view controller

// you can use your own logic to determine if you need to hide status bar
// I just put a var here for now
var hideStatusBar = false
override func preferStatusBarHidden() -> Bool {
    return hideStatus
}


// in other method to manually toggle status bar
func updateUI() {
    hideStatusBar = true
    // call this method to update status bar
    prefersStatusBarHidden()
}
