In order to get the diff to display whitespace similarly to git diff set diffEditor.ignoreTrimWhitespace to false. edit.renderWhitespace is only marginally helpful.

// Controls if the diff editor shows changes in leading or trailing whitespace as diffs
"diffEditor.ignoreTrimWhitespace": false,

To update the settings go to

File > Preferences > User Settings

Note for Mac users: The Preferences menu is under Code not File. For example, Code > Preferences > User Settings.

This opens up a file titled "Default Settings". Expand the area //Editor. Now you can see where all these mysterious editor.* settings are located. Search (CTRL + F) for renderWhitespace. On my box I have:

// Controls how the editor should render whitespace characters, posibilties are 'none', 'boundary', and 'all'. The 'boundary' option does not render single spaces between words.
"editor.renderWhitespace": "none",

To add to the confusion, the left window "Default Settings" is not editable. You need to override them using the right window titled "settings.json". You can copy paste settings from "Default Settings" to "settings.json":

// Place your settings in this file to overwrite default and user settings.
{
     "editor.renderWhitespace": "all",
     "diffEditor.ignoreTrimWhitespace": false
}

I ended up turning off renderWhitespace.

With Spring 3.0.4.RELEASE and higher you can use

<mvc:resources mapping="/resources/**" location="/public-resources/"/>

As seen in Spring Reference.

Google Maps JavaScript API v2 was deprecated in 2011. It is not available anymore.

Full Example (Python 3):
For Python 2.x look into Note below

import re

mylist = ["dog", "cat", "wildcat", "thundercat", "cow", "hooo"]
r = re.compile(".*cat")
newlist = list(filter(r.match, mylist)) # Read Note
print(newlist)

Prints:

['cat', 'wildcat', 'thundercat']

Note:

For Python 2.x developers, filter returns a list already. In Python 3.x filter was changed to return an iterator so it has to be converted to list (in order to see it printed out nicely).

After checking the permission of the folder, it is okay with 744. I had the problem with a plugin that is installed on my WordPress site. The plugin has hooked that are in the corn job I suspected.

With a simple sudo it can fix the issue

sudo git pull origin master

You have it working.

You need to provide the entire certificate chain to curl, since curl no longer ships with any CA certs. Since the cacert option can only use one file, you need to concat the full chain info into 1 file

Copy the certificate chain (from your browser, for example) into DER encoded binary x.509(.cer). Do this for each cert.

Convert the certs into PEM, and concat them into 1 file.

openssl x509 -inform DES -in file1.cer -out file1.pem -text
openssl x509 -inform DES -in file2.cer -out file2.pem -text
openssl x509 -inform DES -in file3.cer -out file3.pem -text

cat *.pem > certRepo

curl --cacert certRepo -u user:passwd -X GET -H 'Content-Type: application/json' "https//somesecureserver.com/rest/field"

I wrote a blog on how to do this here: http://javamemento.blogspot.no/2015/10/using-curl-with-ssl-cert-chain.html

To retrieve your image from byte to base64 string....

Model property:

    public byte[] NomineePhoto { get; set; }

    public string NomineePhoneInBase64Str 
    {
        get {
            if (NomineePhoto == null)
                return "";

            return $"data:image/png;base64,{Convert.ToBase64String(NomineePhoto)}";
        } 
    }

IN view:

   <img style="height:50px;width:50px" src="@item.NomineePhoneInBase64Str" />

Instead of downloading separate java files as suggested by Veer, you could just add this JAR file to your package.

To add the jar file to your project in Eclipse, do the following:

1. Right click on your project, click Build Path > Configure Build Path
2. Goto Libraries tab > Add External JARs
3. Locate the JAR file and add

Another option is to use Javascript:

if (document.getElementById('selectID').value == '1') {
       document.getElementById('optionID').style.color = '#000';

(Not as clean as the CSS attribute selector, but more powerful)

Step-by-Step way to do this:

1. Install Android SDK
2. Start the emulator by going to $SDK_root/emulator.exe
3. Go to command prompt and go to the directory $SDK_root/platform-tools (or else add the path to windows environment)
4. Type in the command adb install
5. Bingo. Your app should be up and running on the emulator

<body topmargin="0" leftmargin="0" rightmargin="0">

I'm not sure where you read this, but this is the accepted way of setting CSS styles inline is:

<body style="margin-top: 0px; margin-left: 0px; margin-right: 0px;">

And with a stylesheet:

body
{
  margin-top: 0px;
  margin-left: 0px;
  margin-right: 0px;
}

Following is my proposed solution.

• Since we need to show only some images in the view pagers so have avoided the cumbersome use of fragments.
  • Implemented the view page indicators (the bottom dots without any extra library or plugin)
  • On the touch of the view page indicators(the dots) also the page navigation is happening.
  • Please don"t forget to add your own images in the resources.
  • Feel free to comment and improve upon it.

If you are running Homebrew, uninstall Postgresql end pg gems:*

$ gem uninstall pg
$ brew uninstall postgresql

Download and run the following script to fix permission on /usr/local:* https://gist.github.com/rpavlik/768518

$ ruby fix_homebrew.rb

Then install Postgres again and pg gem:*

$ brew install postgresql  
$ initdb /usr/local/var/postgres -E utf8

To have launchd start postgresql at login run:

$ ln -sfv /usr/local/opt/postgresql/*.plist ~/Library/LaunchAgents 

Or start manually.

Install pg gem

$ gem install pg

I hope have helped

Thanks for some great answers. Nothing original to add, but here are some progressive rewrites of qneill's answer using some useful Python facilities. I hope you agree they simplify and clarify the code.

import base64


def qneill_encode(key, clear):
    enc = []
    for i in range(len(clear)):
        key_c = key[i % len(key)]
        enc_c = chr((ord(clear[i]) + ord(key_c)) % 256)
        enc.append(enc_c)
    return base64.urlsafe_b64encode("".join(enc))


def qneill_decode(key, enc):
    dec = []
    enc = base64.urlsafe_b64decode(enc)
    for i in range(len(enc)):
        key_c = key[i % len(key)]
        dec_c = chr((256 + ord(enc[i]) - ord(key_c)) % 256)
        dec.append(dec_c)
    return "".join(dec)

enumerate()-- pair the items in a list with their index

iterate over the characters in a string

def encode_enumerate(key, clear):
    enc = []
    for i, ch in enumerate(clear):
        key_c = key[i % len(key)]
        enc_c = chr((ord(ch) + ord(key_c)) % 256)
        enc.append(enc_c)
    return base64.urlsafe_b64encode("".join(enc))


def decode_enumerate(key, enc):
    dec = []
    enc = base64.urlsafe_b64decode(enc)
    for i, ch in enumerate(enc):
        key_c = key[i % len(key)]
        dec_c = chr((256 + ord(ch) - ord(key_c)) % 256)
        dec.append(dec_c)
    return "".join(dec)

build lists using a list comprehension

def encode_comprehension(key, clear):
    enc = [chr((ord(clear_char) + ord(key[i % len(key)])) % 256)
                for i, clear_char in enumerate(clear)]
    return base64.urlsafe_b64encode("".join(enc))


def decode_comprehension(key, enc):
    enc = base64.urlsafe_b64decode(enc)
    dec = [chr((256 + ord(ch) - ord(key[i % len(key)])) % 256)
           for i, ch in enumerate(enc)]
    return "".join(dec)

Often in Python there's no need for list indexes at all. Eliminate loop index variables entirely using zip and cycle:

from itertools import cycle


def encode_zip_cycle(key, clear):
    enc = [chr((ord(clear_char) + ord(key_char)) % 256)
                for clear_char, key_char in zip(clear, cycle(key))]
    return base64.urlsafe_b64encode("".join(enc))


def decode_zip_cycle(key, enc):
    enc = base64.urlsafe_b64decode(enc)
    dec = [chr((256 + ord(enc_char) - ord(key_char)) % 256)
                for enc_char, key_char in zip(enc, cycle(key))]
    return "".join(dec)

and some tests...

msg = 'The quick brown fox jumps over the lazy dog.'
key = 'jMG6JV3QdtRh3EhCHWUi'
print('cleartext: {0}'.format(msg))
print('ciphertext: {0}'.format(encode_zip_cycle(key, msg)))

encoders = [qneill_encode, encode_enumerate, encode_comprehension, encode_zip_cycle]
decoders = [qneill_decode, decode_enumerate, decode_comprehension, decode_zip_cycle]

# round-trip check for each pair of implementations
matched_pairs = zip(encoders, decoders)
assert all([decode(key, encode(key, msg)) == msg for encode, decode in matched_pairs])
print('Round-trips for encoder-decoder pairs: all tests passed')

# round-trip applying each kind of decode to each kind of encode to prove equivalent
from itertools import product
all_combinations = product(encoders, decoders)
assert all(decode(key, encode(key, msg)) == msg for encode, decode in all_combinations)

Setting a variable to null makes sure to break any references to objects in all browsers including circular references being made between the DOM elements and Javascript scopes. By using delete command we are marking objects to be cleared on the next run of the Garbage collection, but if there are multiple variables referencing the same object, deleting a single variable WILL NOT free the object, it will just remove the linkage between that variable and the object. And on the next run of the Garbage collection, only the variable will be cleaned.

Try below code

I will recommend to use error handler while using vlookup because error might occur when the lookup_value is not found.

Private Sub ComboBox1_Change()


    On Error Resume Next
    Ret = Application.WorksheetFunction.VLookup(Me.ComboBox1.Value, Worksheets("Sheet3").Range("Names"), 2, False)
    On Error GoTo 0

    If Ret <> "" Then MsgBox Ret


End Sub

OR

 On Error Resume Next

    Result = Application.VLookup(Me.ComboBox1.Value, Worksheets("Sheet3").Range("Names"), 2, False)

    If Result = "Error 2042" Then
        'nothing found
    ElseIf cell <> Result Then
        MsgBox cell.Value
    End If

    On Error GoTo 0

You can do it by following 3 steps:

 - svn rm old_file_name
 - svn add new_file_name
 - svn commit

Both these will give you the first child node:

console.log(parentElement.firstChild); // or
console.log(parentElement.childNodes[0]);

If you need the first child that is an element node then use:

console.log(parentElement.children[0]);

Edit

Ah, I see your problem now; parentElement is an array.

If you know that getElementsByClassName will only return one result, which it seems you do, you should use [0] to dearray (yes, I made that word up) the element:

var parentElement = document.getElementsByClassName("uniqueClassName")[0];

Use numeric(n,n) where n has enough resolution to round to 1.00. For instance:

declare @discount numeric(9,9)
    , @quantity int
select @discount = 0.999999999
    , @quantity = 10000

select convert(money, @discount * @quantity)

Try with this

Response.Clear();
Response.AppendHeader("Content-Type", "application/vnd.openxmlformats-officedocument.presentationml.presentation");
Response.AppendHeader("Content-Disposition", string.Format("attachment;filename={0}.pptx;", getLegalFileName(CurrentPresentation.Presentation_NM)));
Response.Flush();                
Response.BinaryWrite(masterPresentation.ToArray());
Response.End();

Post the string with raw JSON, and do not forget the double quotation marks!

the solution is to give the Android enough time to proccess cookies. You can find more information here: http://code.walletapp.net/post/46414301269/passing-cookie-to-webview

Yes you need to convert to string in order to find the length.For example

var x=100;// type of x is number
var x=100+"";// now the type of x is string
document.write(x.length);//which would output 3.

On a Mac, you need to use this command:

STATIC_DEPS=true sudo pip install lxml

Just put type="button"

<button type="button"><b>Cancel</b></button>

Because your button is inside a form it is taking default value as submit and type="cancel" doesn't exist.

Along with a number of good answers, what specifically distinguishes a bless-ed reference is that the SV for it picks up an additional FLAGS (OBJECT) and a STASH

perl -MDevel::Peek -wE'
    package Pack  { sub func { return { a=>1 } } }; 
    package Class { sub new  { return bless { A=>10 } } }; 
    $vp  = Pack::func(); print Dump $vp;   say"---"; 
    $obj = Class->new;   print Dump $obj'

Prints, with the same (and irrelevant for this) parts suppressed

SV = IV(0x12d5530) at 0x12d5540
  REFCNT = 1
  FLAGS = (ROK)
  RV = 0x12a5a68
  SV = PVHV(0x12ab980) at 0x12a5a68
    REFCNT = 1
    FLAGS = (SHAREKEYS)
    ...
      SV = IV(0x12a5ce0) at 0x12a5cf0
      REFCNT = 1
      FLAGS = (IOK,pIOK)
      IV = 1
---
SV = IV(0x12cb8b8) at 0x12cb8c8
  REFCNT = 1
  FLAGS = (PADMY,ROK)
  RV = 0x12c26b0
  SV = PVHV(0x12aba00) at 0x12c26b0
    REFCNT = 1
    FLAGS = (OBJECT,SHAREKEYS)
    STASH = 0x12d5300   "Class"
    ...
      SV = IV(0x12c26b8) at 0x12c26c8
      REFCNT = 1
      FLAGS = (IOK,pIOK)
      IV = 10

With that it's known that 1) it is an object 2) what package it belongs to, and this informs its use.

For example, when dereferencing on that variable is encountered ($obj->name), a sub with that name is sought in the package (or hierarchy), the object is passed as the first argument, etc.

This started out as an attempt to cast video from my pc to a tv (with subtitles) eventually using Chromecast. And I ended up in this "does not play mp4" situation. However I seemed to have proved that Chrome will play (exactly the same) mp4 as long as it isn't wrapped in html(5) So here is what I have constructed. I have made a webpage under localhost and in there is a default.htm which contains:-

<!DOCTYPE html>
<html>
<head>
</head>
<body>
<video  controls >
 <source src="sample.mp4" type="video/mp4">
 <track kind="subtitles" src="sample.vtt" label="gcsubs" srclang="eng">
</video>
</body>
</html>

the video and subtitle files are stored in the same folder as default.htm

I have the very latest version of Chrome (just updated this morning)

When I type the appropriate localhost... into my Chrome browser a black square appears with a "GO" arrow and an elapsed time bar, a mute button and an icon which says "CC". If I hit the go arrow, nothing happens (it doesn't change to "pause", the elapsed time doesn't move, and the timer sticks at 0:00. There are no error messages - nothing!

(note that if I input localhost.. to IE11 the video plays!!!!

In Chrome if I enter the disc address of sample.mp4 (i.e. C:\webstore\sample.mp4 then Chrome will play the video fine?.

This last bit is probably a working solution for Chromecast except that I cannot see any subtitles. I really want a solution with working subtitles. I just don't understand what is different in Chrome between the two methods of playing mp4

You can check if string contains numbers only:

Regex.IsMatch(myStringVariable, @"^-?\d+$")

But number can be bigger than Int32.MaxValue or less than Int32.MinValue - you should keep that in mind.

Another option - create extension method and move ugly code there:

public static bool IsInteger(this string s)
{
   if (String.IsNullOrEmpty(s))
       return false;

   int i;
   return Int32.TryParse(s, out i);
}

That will make your code more clean:

if (myStringVariable.IsInteger())
    // ...

        /// <summary>
    /// Returns a new conContractorEntity instance filled with the DataReader's current record data
    /// </summary>
    protected virtual conContractorEntity GetContractorFromReader(IDataReader reader)
    {
        return new conContractorEntity()
        {
            ConId = reader["conId"].ToString().Length > 0 ? int.Parse(reader["conId"].ToString()) : 0,
            ConEmail = reader["conEmail"].ToString(),
            ConCopyAdr = reader["conCopyAdr"].ToString().Length > 0 ? bool.Parse(reader["conCopyAdr"].ToString()) : true,
            ConCreateTime = reader["conCreateTime"].ToString().Length > 0 ? DateTime.Parse(reader["conCreateTime"].ToString()) : DateTime.MinValue
        };
    }

OR

        /// <summary>
    /// Returns a new conContractorEntity instance filled with the DataReader's current record data
    /// </summary>
    protected virtual conContractorEntity GetContractorFromReader(IDataReader reader)
    {
        return new conContractorEntity()
        {
            ConId = GetValue<int>(reader["conId"]),
            ConEmail = reader["conEmail"].ToString(),
            ConCopyAdr = GetValue<bool>(reader["conCopyAdr"], true),
            ConCreateTime = GetValue<DateTime>(reader["conCreateTime"])
        };
    }

// Base methods
        protected T GetValue<T>(object obj)
    {
        if (typeof(DBNull) != obj.GetType())
        {
            return (T)Convert.ChangeType(obj, typeof(T));
        }
        return default(T);
    }

    protected T GetValue<T>(object obj, object defaultValue)
    {
        if (typeof(DBNull) != obj.GetType())
        {
            return (T)Convert.ChangeType(obj, typeof(T));
        }
        return (T)defaultValue;
    }

I think this would be better

$(function() {
$('#myAnchorId').click(function() { 
    var areaValue = $('#area').val();
    $('#area').val(areaValue + 'Whatever you want to enter');
});
});

This worked for me on Windows 8.1 and Windows 10.

git config --global mergetool.meld.path "/c/Program Files (x86)/meld/meld.exe"

On windows, nearly all AMPP (Apache,MySQL,PHP,PHPmyAdmin) packages don't include a mail server (but nearly all naked linuxes do have!). So, when using PHP under windows, you need to setup a mail server!

Imo the best and most simple tool ist this: http://smtp4dev.codeplex.com/

SMTP4Dev is a simple one-file mail server tool that does collect the mails it send (so it does not really sends mail, it just keeps them for development). Perfect tool.

Try dtIngest, it's developed on top of Apache Apex platform. This tool copies data from different sources like HDFS, shared drive, NFS, FTP, Kafka to different destinations. Copying data from remote HDFS cluster to local HDFS cluster is supported by dtIngest. dtIngest runs yarn jobs to copy data in parallel fashion, so it's very fast. It takes care of failure handling, recovery etc. and supports polling directories periodically to do continious copy.

Usage: dtingest [OPTION]... SOURCEURL... DESTINATIONURL example: dtingest hdfs://nn1:8020/source hdfs://nn2:8020/dest

It's easy, you should set server http response header first. The problem is not with your front-end javascript code. You need to return this header:

Access-Control-Allow-Origin:*

or

Access-Control-Allow-Origin:your domain

In Apache config files, the code is like this:

Header set Access-Control-Allow-Origin "*"

In nodejs,the code is like this:

res.setHeader('Access-Control-Allow-Origin','*');

Another thing to try is to re-install ca-certificates as detailed here.

# yum reinstall ca-certificates
...
# update-ca-trust force-enable 
# update-ca-trust extract

And another thing to try is to explicitly allow the one site's certificate in question as described here (especially if the one site is your own server and you already have the .pem in reach).

# cp /your/site.pem /etc/pki/ca-trust/source/anchors/
# update-ca-trust extract

I was running into this exact SO error after upgrading to PHP 5.6 on CentOS 6 trying to access the server itself which has a cheapsslsecurity certificate which maybe it needed to be updated, but instead I installed a letsencrypt certificate and with these two steps above it did the trick. I don't know why the second step was necessary.

Useful Commands

1. The optimal solution could be to try to transform your solution into a form where you don't need to have two readers open at a time. Ideally it could be a single query. I don't have time to do that now.

2. If your problem is so special that you really need to have more readers open simultaneously, and your requirements allow not older than SQL Server 2005 DB backend, then the magic word is MARS (Multiple Active Result Sets). http://msdn.microsoft.com/en-us/library/ms345109%28v=SQL.90%29.aspx. Bob Vale's linked topic's solution shows how to enable it: specify MultipleActiveResultSets=true in your connection string. I just tell this as an interesting possibility, but you should rather transform your solution.

   • in order to avoid the mentioned SQL injection possibility, set the parameters to the SQLCommand itself instead of embedding them into the query string. The query string should only contain the references to the parameters what you pass into the SqlCommand.

Use the isin method:

rpt[rpt['STK_ID'].isin(stk_list)]

Morgan :- Morgan is a middleware which will help us to identify the clients who are accessing our application. Basically a logger.

To Use Morgan, We need to follow below steps :-

1. Install the morgan using below command:

npm install --save morgan

This will add morgan to json.package file

2. Include the morgan in your project

var morgan = require('morgan');

3> // create a write stream (in append mode)

var accessLogStream = fs.createWriteStream(
      path.join(__dirname, 'access.log'), {flags: 'a'}
 );
// setup the logger 
app.use(morgan('combined', {stream: accessLogStream}));

Note: Make sure you do not plumb above blindly make sure you have every conditions where you need .

Above will automatically create a access.log file to your root once user will access your app.

if you have a the input password in a variable and you want to match exactly 123456 then anchors will help you:

/^123456$/

in perl the test for matching the password would be something like

print "MATCH_OK" if ($input_pass=~/^123456$/);

EDIT:

bart kiers is right tho, why don't you use a strcmp() for this? every language has it in its own way

as a second thought, you may want to consider a safer authentication mechanism :)

In my case the reason was fairly trivial.

I had known that the SSL verification had worked until a few days earlier, and was infact working on a different machine.

My next step was to compare the certificate contents and size between the machine on which verification was working, and the one on which it was not.

This quickly led to me determining that the Certificate on the 'incorrectly' working machine was not good, and once I replaced it with the 'good' cert, everything was fine.

Note: This answer does not explicitly answer the asked question. the other answers do it. Since the question is specific to a scenario and the raised exception is general, This answer points to the general case.

Hash values are just integers which are used to compare dictionary keys during a dictionary lookup quickly.

Internally, hash() method calls __hash__() method of an object which are set by default for any object.

Converting a nested list to a set

>>> a = [1,2,3,4,[5,6,7],8,9]
>>> set(a)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: unhashable type: 'list'

This happens because of the list inside a list which is a list which cannot be hashed. Which can be solved by converting the internal nested lists to a tuple,

>>> set([1, 2, 3, 4, (5, 6, 7), 8, 9])
set([1, 2, 3, 4, 8, 9, (5, 6, 7)])

Explicitly hashing a nested list

>>> hash([1, 2, 3, [4, 5,], 6, 7])
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: unhashable type: 'list'


>>> hash(tuple([1, 2, 3, [4, 5,], 6, 7]))
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: unhashable type: 'list'

>>> hash(tuple([1, 2, 3, tuple([4, 5,]), 6, 7]))
-7943504827826258506

The solution to avoid this error is to restructure the list to have nested tuples instead of lists.

I would seriously consider the use of Boost, particularly boost::posix_time::ptime and boost::posix_time::time_duration (at http://www.boost.org/doc/libs/1_38_0/doc/html/date_time/posix_time.html).

It's cross-platform, easy to use, and in my experience provides the highest level of time resolution an operating system provides. Possibly also very important; it provides some very nice IO operators.

To use it to calculate the difference in program execution (to microseconds; probably overkill), it would look something like this [browser written, not tested]:

ptime time_start(microsec_clock::local_time());
//... execution goes here ...
ptime time_end(microsec_clock::local_time());
time_duration duration(time_end - time_start);
cout << duration << '\n';

Additional Solution: use Restul api wrapper libraries written in Java / python / Ruby - An object oriented wrappers which aim to provide a more conventionally way of controlling a Jenkins server.

Using @Saikh's answer above, the 2nd option, you can add a space between the time itself and the AM or PM.

REVERSE(LEFT(REVERSE(CONVERT(VARCHAR(20),CONVERT(TIME,myDateTime),100)),2) + ' ' + SUBSTRING(REVERSE(CONVERT(VARCHAR(20),CONVERT(TIME,myDateTime),100)),3,20)) AS [Time],

Messy I know, but it's the solution I chose. Strange that the CONVERT() doesn't add that space automatically. SQL Server 2008 R2

Easiest way is probably

pip3 -V

This will show you where your pip is installed and therefore where your packages are located.

In my experience, this message occurs when the primary file (.mdf) has no space to save the metadata of the database. This file include the system tables and they only save their data into it.

Make some space in the file and the commands works again. That's all, Enjoy

If you want to stream any webpage, you can use the method below.

import java.io.*;
import java.net.*;

public class c {

   public static String getHTML(String urlToRead) throws Exception {
      StringBuilder result = new StringBuilder();
      URL url = new URL(urlToRead);
      HttpURLConnection conn = (HttpURLConnection) url.openConnection();
      conn.setRequestMethod("GET");
      try (var reader = new BufferedReader(
                  new InputStreamReader(conn.getInputStream()))) {
          for (String line; (line = reader.readLine()) != null; ) {
              result.append(line);
          }
      }
      return result.toString();
   }

   public static void main(String[] args) throws Exception
   {
     System.out.println(getHTML(args[0]));
   }
}

Another method that can be used to copy tables from the source database to the destination one is the SQL Server Export and Import wizard, which is available in SQL Server Management Studio.

You have the choice to export from the source database or import from the destination one in order to transfer the data.

This method is a quick way to copy tables from the source database to the destination one, if you arrange to copy tables having no concern with the tables’ relationships and orders.

When using this method, the tables’ indexes and keys will not be transferred. If you are interested in copying it, you need to generate scripts for these database objects.

If these are Foreign Keys, connecting these tables together, you need to export the data in the correct order, otherwise the export wizard will fail.

Feel free to read more about this method, as well as about some more methods (including generate scripts, SELECT INTO and third party tools) in this article: https://www.sqlshack.com/how-to-copy-tables-from-one-database-to-another-in-sql-server/

Usually this happens if something is wrong with the byte array.

File.WriteAllBytes("filename.PDF", Byte[]);

This creates a new file, writes the specified byte array to the file, and then closes the file. If the target file already exists, it is overwritten.

Asynchronous implementation of this is also available.

public static System.Threading.Tasks.Task WriteAllBytesAsync 
(string path, byte[] bytes, System.Threading.CancellationToken cancellationToken = null);

First, you don't need to do all that. In particular, the strcpy is redundant - you don't need to copy a string just to printf it. Your message can be defined with that string in place.

Second, you've not allowed enough space for that "Hello, World!" string (message needs to be at least 14 characters, allowing the extra one for the null terminator).

On the why, though, it's history. In assembler, there are no strings, only bytes, words etc. Pascal had strings, but there were problems with static typing because of that - string[20] was a different type that string[40]. There were languages even in the early days that avoided this issue, but that caused indirection and dynamic allocation overheads which were much more of an efficiency problem back then.

C simply chose to avoid the overheads and stay very low level. Strings are character arrays. Arrays are very closely related to pointers that point to their first item. When array types "decay" to pointer types, the buffer-size information is lost from the static type, so you don't get the old Pascal string issues.

In C++, there's the std::string class which avoids a lot of these issues - and has the dynamic allocation overheads, but these days we usually don't care about that. And in any case, std::string is a library class - there's C-style character-array handling underneath.

I was getting the same error in my IBM Websphere with c3p0 jar files. I have Oracle 10g database. I simply added the oraclejdbc.jar files in the Application server JVM in IBM Classpath using Websphere Console and the error was resolved.

The oraclejdbc.jar should be set with your C3P0 jar files in your Server Class path whatever it be tomcat, glassfish of IBM.

I agree totally with the OP point of view. Assert.assertFalse(expected.equals(actual)) is not a natural way to express an inequality.
But I would argue that further than Assert.assertEquals(), Assert.assertNotEquals() works but is not user friendly to document what the test actually asserts and to understand/debug as the assertion fails.
So yes JUnit 4.11 and JUnit 5 provides Assert.assertNotEquals() (Assertions.assertNotEquals() in JUnit 5) but I really avoid using them.

As alternative, to assert the state of an object I general use a matcher API that digs into the object state easily, that document clearly the intention of the assertions and that is very user friendly to understand the cause of the assertion failure.

Here is an example.
Suppose I have an Animal class which I want to test the createWithNewNameAndAge() method, a method that creates a new Animal object by changing its name and its age but by keeping its favorite food.
Suppose I use Assert.assertNotEquals() to assert that the original and the new objects are different.
Here is the Animal class with a flawed implementation of createWithNewNameAndAge() :

public class Animal {

    private String name;
    private int age;
    private String favoriteFood;

    public Animal(String name, int age, String favoriteFood) {
        this.name = name;
        this.age = age;
        this.favoriteFood = favoriteFood;
    }

    // Flawed implementation : use this.name and this.age to create the 
    // new Animal instead of using the name and age parameters
    public Animal createWithNewNameAndAge(String name, int age) {
        return new Animal(this.name, this.age, this.favoriteFood);
    }

    public String getName() {
        return name;
    }

    public int getAge() {
        return age;
    }

    public String getFavoriteFood() {
        return favoriteFood;
    }

    @Override
    public String toString() {
        return "Animal [name=" + name + ", age=" + age + ", favoriteFood=" + favoriteFood + "]";
    }

    @Override
    public int hashCode() {
        final int prime = 31;
        int result = 1;
        result = prime * result + age;
        result = prime * result + ((favoriteFood == null) ? 0 : favoriteFood.hashCode());
        result = prime * result + ((name == null) ? 0 : name.hashCode());
        return result;
    }

    @Override
    public boolean equals(Object obj) {
        if (!(obj instanceof Animal)) return false;

        Animal other = (Animal) obj;
        return age == other.age && favoriteFood.equals(other.favoriteFood) &&
                name.equals(other.name);
    }

}

JUnit 4.11+ (or JUnit 5) both as test runner and assertion tool

@Test
void assertListNotEquals_JUnit_way() {
    Animal scoubi = new Animal("scoubi", 10, "hay");
    Animal littleScoubi = scoubi.createWithNewNameAndAge("little scoubi", 1);
    Assert.assertNotEquals(scoubi, littleScoubi);
}

The test fails as expected but the cause provided to the developer is really not helpful. It just says that the values should be different and output the toString() result invoked on the actual Animal parameter :

java.lang.AssertionError: Values should be different. Actual: Animal

[name=scoubi, age=10, favoriteFood=hay]

at org.junit.Assert.fail(Assert.java:88)

Ok the objects are not equals. But where is the problem ?
Which field is not correctly valued in the tested method ? One ? Two ? All of them ?
To discover it you have to dig in the createWithNewNameAndAge() implementation/use a debugger while the testing API would be much more friendly if it would make for us the differential between which is expected and which is gotten.

JUnit 4.11 as test runner and a test Matcher API as assertion tool

Here the same scenario of test but that uses AssertJ (an excellent test matcher API) to make the assertion of the Animal state: :

import org.assertj.core.api.Assertions;

@Test
void assertListNotEquals_AssertJ() {
    Animal scoubi = new Animal("scoubi", 10, "hay");
    Animal littleScoubi = scoubi.createWithNewNameAndAge("little scoubi", 1);
    Assertions.assertThat(littleScoubi)
              .extracting(Animal::getName, Animal::getAge, Animal::getFavoriteFood)
              .containsExactly("little scoubi", 1, "hay");
}

Of course the test still fails but this time the reason is clearly stated :

java.lang.AssertionError:

Expecting:

<["scoubi", 10, "hay"]>

to contain exactly (and in same order):

<["little scoubi", 1, "hay"]>

but some elements were not found:

<["little scoubi", 1]>

and others were not expected:

<["scoubi", 10]>

at junit5.MyTest.assertListNotEquals_AssertJ(MyTest.java:26)

We can read that for Animal::getName, Animal::getAge, Animal::getFavoriteFood values of the returned Animal, we expect to have these value :

"little scoubi", 1, "hay" 

but we have had these values :

"scoubi", 10, "hay"

So we know where investigate : name and age are not correctly valued. Additionally, the fact of specifying the hay value in the assertion of Animal::getFavoriteFood() allows also to more finely assert the returned Animal. We want that the objects be not the same for some properties but not necessarily for every properties.
So definitely, using a matcher API is much more clear and flexible.

If you accept using another jQuery dependent tool, I would recommend using Tabulator. Then you will not need to write HTML or any other DOM generating code, while maintaining great flexibility regarding the formatting and processing of the table data.

For another working example using Node, you can look at the MMM-Tabulator demo project.

I'd just add to the answers the "why?".

. is standard member access operator that has a higher precedence than * pointer operator.

When you are trying to access a struct's internals and you wrote it as *foo.bar then the compiler would think to want a 'bar' element of 'foo' (which is an address in memory) and obviously that mere address does not have any members.

Thus you need to ask the compiler to first dereference whith (*foo) and then access the member element: (*foo).bar, which is a bit clumsy to write so the good folks have come up with a shorthand version: foo->bar which is sort of member access by pointer operator.

Add the 'columns' parameter:

frame = pd.DataFrame({
        'one thing':[1,2,3,4],
        'second thing':[0.1,0.2,1,2],
        'other thing':['a','e','i','o']},
        columns=['one thing', 'second thing', 'other thing']
)

The range(n) in python returns from 0 to n-1. Respectively, the range(1,n) from 1 to n-1. So, if you want to omit the first value and get also the last value (n) you can do it very simply using the following code.

for i in range(1, n + 1):
        print(i) #prints from 1 to n

It is called an interface. Many OO languages have this feature. You might want to read through the php explanation here: http://de2.php.net/interface

Use an ID to uniquely identify the checkbox. Your current example is trying to select the checkbox with an id of '#chk0':

<input type="checkbox" id="chk0" name="chk0" value="true" disabled>

$('#chk0').attr("disabled", "disabled");

You'll also need to remove the attribute for disabled to enable the checkbox. Something like:

$('#chk0').removeAttr("disabled");

See the docs for removeAttr

The value XHTML for disabling/enabling an input element is as follows:

<input type="checkbox" id="chk0" name="chk0" value="true" disabled="disabled" />
<input type="checkbox" id="chk0" name="chk0" value="true" />

Note that it's the absence of the disabled attribute that makes the input element enabled.

I prefer fork + execlp for "more fine-grade" control as doron mentioned. Example code shown below.

Store you command in a char array parameters, and malloc space for the result.

int fd[2];
pipe(fd);
if ( (childpid = fork() ) == -1){
   fprintf(stderr, "FORK failed");
   return 1;
} else if( childpid == 0) {
   close(1);
   dup2(fd[1], 1);
   close(fd[0]);
   execlp("/bin/sh","/bin/sh","-c",parameters,NULL);
}
wait(NULL);
read(fd[0], result, RESULT_SIZE);
printf("%s\n",result);

Set sh1 = Worksheets(filenum(lngPosition)).Activate

You are getting Subscript out of range error error becuase it cannot find that Worksheet.

Also please... please... please do not use .Select/.Activate/Selection/ActiveCell You might want to see How to Avoid using Select in Excel VBA Macros.

1.makesure your .zip file is an valid Eclipse Plugin

Note:

1. that means: your .zip file contains folders features and plugins, like this:
2. for new version Eclipse Plugin, it may also include another two files content.jar, artifacts.jar, example:

but this is not important for the plugin,

the most important is the folders features and plugins

which contains the necessary xxx.jar,

for example:

2.for valid Eclipse Plugin .zip file, you have two methods to install it

(1) auto install

Help -> Install New Software -> Add -> Archive

then choose your .zip file

example:

(2) manual install

1. uncompress .zip file -> got folders features and plugins
2. copy them into the root folder of Eclipse, which already contains features and plugins
3. restart Eclipse, then you can see your installed plugin's settings in Window -> Preferences

for more detailed explanation, can refer my post (written in Chinese):

Summary methods of install Eclipse Plugin from .zip

A clean and functional solution

const combineFilters = (...filters) => (item) => {
    return filters.map((filter) => filter(item)).every((x) => x === true);
};

then you use it like so:

const filteredArray = arr.filter(combineFilters(filterFunc1, filterFunc2));

and filterFunc1 for example might look like this:

const filterFunc1 = (item) => {
  return item === 1 ? true : false;
};

XPath 1.0, which is what MS implements, does not have the idea of a default namespace. So try this:

XDocument xdoc = XDocument.Load(@"C:\SampleXML.xml");
XmlNamespaceManager xnm = new XmlNamespaceManager(new NameTable()); 
xnm.AddNamespace("x", "http://demo.com/2011/demo-schema");
Console.WriteLine(xdoc.XPathSelectElement("/x:Report/x:ReportInfo/x:Name", xnm) == null);

The general format, from the @link section of the javadoc documentation, is:

Examples

Method in the same class:

/** See also {@link #myMethod(String)}. */
void foo() { ... }

Method in a different class, either in the same package or imported:

/** See also {@link MyOtherClass#myMethod(String)}. */
void foo() { ... }

Method in a different package and not imported:

/** See also {@link com.mypackage.YetAnotherClass#myMethod(String)}. */
void foo() { ... }

Label linked to method, in plain text rather than code font:

/** See also this {@linkplain #myMethod(String) implementation}. */
void foo() { ... }

A chain of method calls, as in your question. We have to specify labels for the links to methods outside this class, or we get getFoo().Foo.getBar().Bar.getBaz(). But these labels can be fragile during refactoring -- see "Labels" below.

/**
 * A convenience method, equivalent to 
 * {@link #getFoo()}.{@link Foo#getBar() getBar()}.{@link Bar#getBaz() getBaz()}.
 * @return baz
 */
public Baz fooBarBaz()

Labels

Automated refactoring may not affect labels. This includes renaming the method, class or package; and changing the method signature.

Therefore, provide a label only if you want different text than the default.

For example, you might link from human language to code:

/** You can also {@linkplain #getFoo() get the current foo}. */
void setFoo( Foo foo ) { ... }

Or you might link from a code sample with text different than the default, as shown above under "A chain of method calls." However, this can be fragile while APIs are evolving.

Type erasure and #member

If the method signature includes parameterized types, use the erasure of those types in the javadoc @link. For example:

int bar( Collection<Integer> receiver ) { ... }

/** See also {@link #bar(Collection)}. */
void foo() { ... }

I'd suggest using intermediary third table for storing tags<=>items associations, since we have many-to-many relations between tags and items, i.e. one item can be associated with multiple tags and one tag can be associated with multiple items. HTH, Valve.

I used jQuery AutoSize. When I tried using Elastic it frequently gave me bogus heights (really tall textarea's). jQuery AutoSize has worked well and hasn't had this issue.

The selector should not be #input. That means a field with id="input" which is not your case. You want:

$('#chag_sort').val(sort2);

Or if your hidden input didn't have an unique id but only a name="chag_sort":

$('input[name="chag_sort"]').val(sort2);

• Very Simple

  private void button1_Click(object sender, EventArgs e)
  {
      ListViewItem item = new ListViewItem();
      item.SubItems.Add(textBox2.Text);
      item.SubItems.Add(textBox3.Text);
      item.SubItems.Add(textBox4.Text);
      listView1.Items.Add(item);
      textBox2.Clear();
      textBox3.Clear();
      textBox4.Clear();
  }
  

• You can also Do this stuff...

      ListViewItem item = new ListViewItem();
      item.SubItems.Add("Santosh");
      item.SubItems.Add("26");
      item.SubItems.Add("India");
  

Surprisingly, none of answers talk about how it is achieved by hibernate behind the screens.

Lazy loading is a design pattern that is effectively used in hibernate for performance reasons which involves following techniques.

1. Byte code instrumentation:

Enhances the base class definition with hibernate hooks to intercept all the calls to that entity object.

Done either at compile time or run[load] time

1.1 Compile time

• Post compile time operation

• Mostly by maven/ant plugins

1.2 Run time

• If no compile time instrumentation is done, this is created at run time Using libraries like javassist

2. Proxies

The entity object that Hibernate returns are proxy of the real type.

See also: Javassist. What is the main idea and where real use?

Here is another variation on the Bootstrap 4.1 Navbar with multi-level dropdown. This one uses minimal CSS for the submenu, and can be re-positioned as desired:

https://www.codeply.com/go/nG6iMAmI2X

.dropdown-submenu {
  position: relative;
}

.dropdown-submenu .dropdown-menu {
  top: 0;
  left: 100%;
  margin-top: -1px;
}

jQuery to control display of submenus:

$('.dropdown-submenu > a').on("click", function(e) {
    var submenu = $(this);
    $('.dropdown-submenu .dropdown-menu').removeClass('show');
    submenu.next('.dropdown-menu').addClass('show');
    e.stopPropagation();
});

$('.dropdown').on("hidden.bs.dropdown", function() {
    // hide any open menus when parent closes
    $('.dropdown-menu.show').removeClass('show');
});

See this answer for activating the Bootstrap 4 submenus on hover

None of the above solutions worked for me and I don't have admin rights on my laptop, but they eventually led me to the git tools credential storage doc :

My setup Windows 10 | git version 2.18.0.windows.1 | Clone through HTTPS link

This solution works if you use wincred as credential helper :

> git config --global credential.helper
wincred

Changing the helper to "cache" should do the trick, as it will ask you to provide your credentials again. To set it to cache, just type :

> git config --global credential.helper cache

Check your update is active:

> git config --global credential.helper
cache

You should now be able to clone / pull / fetch as before.

I would change zoom for transform in all cases because, as explained by other answers, they are not equivalent. In my case it was also necessary to apply transform-origin property to place the items where I wanted.

This worked for me in Chome, Safari and Firefox:

transform: scale(0.4);
transform-origin: top left;
-moz-transform: scale(0.4);
-moz-transform-origin: top left;

I think the question is getting at the fact that C# needs another keyword, for precisely this sort of situation. You want a method whose return value depends only on the type on which it is called. You can't call it "static" if said type is unknown. But once the type becomes known, it will become static. "Unresolved static" is the idea -- it's not static yet, but once we know the receiving type, it will be. This is a perfectly good concept, which is why programmers keep asking for it. But it didn't quite fit into the way the designers thought about the language.

Since it's not available, I have taken to using non-static methods in the way shown below. Not exactly ideal, but I can't see any approach that makes more sense, at least not for me.

public interface IZeroWrapper<TNumber> {
  TNumber Zero {get;}
}

public class DoubleWrapper: IZeroWrapper<double> {
  public double Zero { get { return 0; } }
}

Here is a proper explanation of "still reachable":

"Still reachable" are leaks assigned to global and static-local variables. Because valgrind tracks global and static variables it can exclude memory allocations that are assigned "once-and-forget". A global variable assigned an allocation once and never reassigned that allocation is typically not a "leak" in the sense that it does not grow indefinitely. It is still a leak in the strict sense, but can usually be ignored unless you are pedantic.

Local variables that are assigned allocations and not free'd are almost always leaks.

Here is an example

int foo(void)
{
    static char *working_buf = NULL;
    char *temp_buf;
    if (!working_buf) {
         working_buf = (char *) malloc(16 * 1024);
    }
    temp_buf = (char *) malloc(5 * 1024);

    ....
    ....
    ....

}

Valgrind will report working_buf as "still reachable - 16k" and temp_buf as "definitely lost - 5k".

You need to use the jQuery AJAX or XMLHttpRequest() for post the data to the server. After data posting you can redirect your page to another page by window.location.href.

Example:

 var xhttp = new XMLHttpRequest();
  xhttp.onreadystatechange = function() {
    if (this.readyState == 4 && this.status == 200) {
      window.location.href = 'https://website.com/my-account';
    }
  };
  xhttp.open("POST", "demo_post.asp", true);
  xhttp.send();

Initialize barbuttonItem like following:

let pauseButton = UIBarButtonItem(image: UIImage(named: "big"),
                                  style: .plain,
                                  target: self,
                                  action: #selector(PlaybackViewController.pause))

In First activity:

ArrayList<ContactBean> fileList = new ArrayList<ContactBean>();
Intent intent = new Intent(MainActivity.this, secondActivity.class);
intent.putExtra("FILES_TO_SEND", fileList);
startActivity(intent);

In receiver activity:

ArrayList<ContactBean> filelist =  (ArrayList<ContactBean>)getIntent().getSerializableExtra("FILES_TO_SEND");`

Look the path for example this import is not correct import Navbar from '@/components/Navbar.vue' should look like this ** import Navbar from './components/Navbar.vue'**

Another server you can try http://tjws.sf.net, actually it already provides Android enabled version.

If you want to use a string as a variable name, you can use assign:

var1="string_name"

assign(var1, c(5,4,5,6,7))

string_name 

[1] 5 4 5 6 7

My problem was in web.xml file. In one <servlet-mapping> there was an error inside <url-pattern>: I forgot to add / before url.

Here is the sample worked in Python: This sample returns the results inline.

from pymongo import MongoClient
from bson.code import Code

mapper = Code("""
    function() {
                  for (var key in this) { emit(key, null); }
               }
""")
reducer = Code("""
    function(key, stuff) { return null; }
""")

distinctThingFields = db.things.map_reduce(mapper, reducer
    , out = {'inline' : 1}
    , full_response = True)
## do something with distinctThingFields['results']

Just in addition to the above answers, for the question where and when you should call getLocationOnScreen?

For any information that is related to the view, will be available only after the view has been laid out(created) on the screen. So to get the location put your code inside view.post(Runnable) which is called after view has been laid out, like this:

view.post(new Runnable() {
            @Override
            public void run() {

               // This code will run when view created and rendered on screen

               // So as the answer to this question, you can put the code here
               int[] location = new int[2];
               myView.getLocationOnScreen(location);
               int x = location[0];
               int y = location[1];
            }
        });  

I know I am posting this answer little late, but I felt it is worth using Google's fuse location provider service to get the current location.

Main features of this api are :

1.Simple APIs: Lets you choose your accuracy level as well as power consumption.

2.Immediately available: Gives your apps immediate access to the best, most recent location.

3.Power-efficiency: It chooses the most efficient way to get the location with less power consumptions

4.Versatility: Meets a wide range of needs, from foreground uses that need highly accurate location to background uses that need periodic location updates with negligible power impact.

It is flexible in while updating in location also. If you want current location only when your app starts then you can use getLastLocation(GoogleApiClient) method.

If you want to update your location continuously then you can use requestLocationUpdates(GoogleApiClient,LocationRequest, LocationListener)

You can find a very nice blog about fuse location here and google doc for fuse location also can be found here.

Update

According to developer docs starting from Android O they have added new limits on background location.

If your app is running in the background, the location system service computes a new location for your app only a few times each hour. This is the case even when your app is requesting more frequent location updates. However if your app is running in the foreground, there is no change in location sampling rates compared to Android 7.1.1 (API level 25).

In this case, the solution was to change the classpath order of the module in my war file. That is, open up the war application in the WAS console under and select the client module(s). In the module configuration, set the class-loading to be "parent last".

This is found in the WAS console:

• Applicatoins -> Application Types -> WebSphere Enterprise Applications
• Click link representing your application (war)
• Click "Manage Modules" under "Modules" section
• Click link for the underlying module(s)
• Change "Class loader order" to be "(parent last)".

This can be done even without renaming the local branch in three simple steps:

1. Go to your repository in GitHub
2. Create a new branch from the old branch which you want to rename
3. Delete the old branch

console.log(data)

The basic problem while migrating from MySQL I faced was, I thought of the term database to be same in PostgreSQL also, but it is not. So if we are going to switch the database from our application or pgAdmin, the result would not be as expected. As in my case, we have separate schemas (Considering PostgreSQL terminology here.) for each customer and separate admin schema. So in application, I have to switch between schemas.

For this, we can use the SET search_path command. This does switch the current schema to the specified schema name for the current session.

example:

SET search_path = different_schema_name;

This changes the current_schema to the specified schema for the session. To change it permanently, we have to make changes in postgresql.conf file.

If waiting for all tasks in the ExecutorService to finish isn't precisely your goal, but rather waiting until a specific batch of tasks has completed, you can use a CompletionService — specifically, an ExecutorCompletionService.

The idea is to create an ExecutorCompletionService wrapping your Executor, submit some known number of tasks through the CompletionService, then draw that same number of results from the completion queue using either take() (which blocks) or poll() (which does not). Once you've drawn all the expected results corresponding to the tasks you submitted, you know they're all done.

Let me state this one more time, because it's not obvious from the interface: You must know how many things you put into the CompletionService in order to know how many things to try to draw out. This matters especially with the take() method: call it one time too many and it will block your calling thread until some other thread submits another job to the same CompletionService.

There are some examples showing how to use CompletionService in the book Java Concurrency in Practice.

As always in python, there are of course several ways to do it, but there is one obvious way to do it.

tmpdict["ONE"]["TWO"]["THREE"] is the obvious way to do it.

When that does not fit well with your algorithm, that may be a hint that your structure is not the best for the problem.

If you just want to just save you repetative typing, you can of course alias a subset of the dict:

>>> two_dict = tmpdict['ONE']['TWO'] # now you can just write two_dict for tmpdict['ONE']['TWO']
>>> two_dict["spam"] = 23
>>> tmpdict
{'ONE': {'TWO': {'THREE': 10, 'spam': 23}}}

According to the Oracle PLSQL language definition, a character literal can contain "any printable character in the character set". https://docs.oracle.com/cd/A97630_01/appdev.920/a96624/02_funds.htm#2876

@Robert Love's answer exhibits a best practice for readable code, but you can also just type in the linefeed character into the code. Here is an example from a Linux terminal using sqlplus:

SQL> set serveroutput on
SQL> begin   
  2  dbms_output.put_line( 'hello' || chr(10) || 'world' );
  3  end;
  4  /
hello
world

PL/SQL procedure successfully completed.

SQL> begin
  2  dbms_output.put_line( 'hello
  3  world' );
  4  end;
  5  /
hello
world

PL/SQL procedure successfully completed.

Instead of the CHR( NN ) function you can also use Unicode literal escape sequences like u'\0085' which I prefer because, well you know we are not living in 1970 anymore. See the equivalent example below:

SQL> begin
  2  dbms_output.put_line( 'hello' || u'\000A' || 'world' );
  3  end;
  4  /
hello
world

PL/SQL procedure successfully completed.

For fair coverage I guess it is worth noting that different operating systems use different characters/character sequences for end of line handling. You've got to have a think about the context in which your program output is going to be viewed or printed, in order to determine whether you are using the right technique.

• Microsoft Windows: CR/LF or u'\000D\000A'
• Unix (including Apple MacOS): LF or u'\000A'
• IBM OS390: NEL or u'\0085'
• HTML: '<BR>'
• XHTML: '<br />'
• etc. etc.

As I can see, you are comparing the message with the empty string using ==.

Its very hard to write the full code, but I can tell the flow of code - first, create db class & method inide that which will return the connection. second, create a servelet(ex-login.java) & import that db class onto that servlet. third, create instance of imported db class with the help of new operator & call the connection method of that db class. fourth, creaet prepared statement & execute statement & put this code in try catch block for exception handling.Use if-else condition in the try block to navigate your login page based on success or failure.

I hope, it will help you. If any problem, then please revert.

If you want to generate a backtrace, you are looking for debug_backtrace and/or debug_print_backtrace.

The first one will, for instance, get you an array like this one (quoting the manual) :

array(2) {
[0]=>
array(4) {
    ["file"] => string(10) "/tmp/a.php"
    ["line"] => int(10)
    ["function"] => string(6) "a_test"
    ["args"]=>
    array(1) {
      [0] => &string(6) "friend"
    }
}
[1]=>
array(4) {
    ["file"] => string(10) "/tmp/b.php"
    ["line"] => int(2)
    ["args"] =>
    array(1) {
      [0] => string(10) "/tmp/a.php"
    }
    ["function"] => string(12) "include_once"
  }
}

They will apparently not flush the I/O buffer, but you can do that yourself, with flush and/or ob_flush.

(see the manual page of the first one to find out why the "and/or" ;-) )

Clear all files from temporary folder (C:\Users\user_name\AppData\Local\Temp\Temporary ASP.NET Files\project folder)

No, because that would open up the floodgates for phishing. The only part of the URI you can change is the fragment (everything after the #). You can do so by setting window.location.hash.

 [NSString stringWithFormat: @"first unixtime is %ld",message,(long)[[NSDate date] timeIntervalSince1970]];

 [NSString stringWithFormat: @"second unixtime is %ld",message,[[NSDate date] timeIntervalSince1970]];

You can either use the first one or try the code below which is equally efficient

I've been searching the internet for RNG for a while now. Everything I saw was either TOO complex or was just not what I was looking for. After reading a few articles I was able to come up with this simple code.

{
  Random rnd = new Random(DateTime.Now.Millisecond);
  int[] b = new int[10] { 5, 8, 1, 7, 3, 2, 9, 0, 4, 6 };
  textBox1.Text = Convert.ToString(b[rnd.Next(10)])
}

Simple explanation,

1. create a 1 dimensional integer array.
2. full up the array with unordered numbers.
3. use the rnd.Next to get the position of the number that will be picked.

This works well.

To obtain a random number less than 100 use

{
  Random rnd = new Random(DateTime.Now.Millisecond);
  int[] b = new int[10] { 5, 8, 1, 7, 3, 2, 9, 0, 4, 6 };
  int[] d = new int[10] { 9, 4, 7, 2, 8, 0, 5, 1, 3, 4 };
  textBox1.Text = Convert.ToString(b[rnd.Next(10)]) + Convert.ToString(d[rnd.Next(10)]);
}

and so on for 3, 4, 5, and 6 ... digit random numbers.

Hope this assists someone positively.

You should probably read some JS tutorials like this one.

Not sure if goto exists in JS at all, but, either way, it encourages bad coding style and should be avoided.

You could do:

while ( some_condition ){
    alert('RINSE');
    alert('LATHER');
}

For SQL Management studio I used a variation of BWS' answer. This gets the data to the right of '=', or NULL if the symbol doesn't exist:

   CASE WHEN (RIGHT(supplier_reference, CASE WHEN (CHARINDEX('=',supplier_reference,0)) = 0 THEN
    0 ELSE CHARINDEX('=', supplier_reference) -1 END)) <> '' THEN (RIGHT(supplier_reference, CASE WHEN (CHARINDEX('=',supplier_reference,0)) = 0 THEN
    0 ELSE CHARINDEX('=', supplier_reference) -1 END)) ELSE NULL END

Spring lets you define multiple contexts in a parent-child hierarchy.

The applicationContext.xml defines the beans for the "root webapp context", i.e. the context associated with the webapp.

The spring-servlet.xml (or whatever else you call it) defines the beans for one servlet's app context. There can be many of these in a webapp, one per Spring servlet (e.g. spring1-servlet.xml for servlet spring1, spring2-servlet.xml for servlet spring2).

Beans in spring-servlet.xml can reference beans in applicationContext.xml, but not vice versa.

All Spring MVC controllers must go in the spring-servlet.xml context.

In most simple cases, the applicationContext.xml context is unnecessary. It is generally used to contain beans that are shared between all servlets in a webapp. If you only have one servlet, then there's not really much point, unless you have a specific use for it.

I just had the same problem and literally nothing worked for me. The error was showing kerberos is causing the problem and it was one of the mongoose dependencies. Since I'm on Ubuntu, I thought there might be permission issues somewhere between the globally installed packages -- in /usr/lib/node_modules via sudo, and those which are on the user space.

I installed mongoose globally -- with sudo of course, and everything began working as expected.

P.S. The kerberos package now also is installed globally next to mongoose, however I can't remember if I did it deliberately -- while I was trying to solve the problem, or if it was there from the beginning.

Pandas dataframe copy warning

When you go and do something like this:

quote_df = quote_df.ix[:,[0,3,2,1,4,5,8,9,30,31]]

pandas.ix in this case returns a new, stand alone dataframe.

Any values you decide to change in this dataframe, will not change the original dataframe.

This is what pandas tries to warn you about.

Why .ix is a bad idea

The .ix object tries to do more than one thing, and for anyone who has read anything about clean code, this is a strong smell.

Given this dataframe:

df = pd.DataFrame({"a": [1,2,3,4], "b": [1,1,2,2]})

Two behaviors:

dfcopy = df.ix[:,["a"]]
dfcopy.a.ix[0] = 2

Behavior one: dfcopy is now a stand alone dataframe. Changing it will not change df

df.ix[0, "a"] = 3

Behavior two: This changes the original dataframe.

Use .loc instead

The pandas developers recognized that the .ix object was quite smelly[speculatively] and thus created two new objects which helps in the accession and assignment of data. (The other being .iloc)

.loc is faster, because it does not try to create a copy of the data.

.loc is meant to modify your existing dataframe inplace, which is more memory efficient.

.loc is predictable, it has one behavior.

The solution

What you are doing in your code example is loading a big file with lots of columns, then modifying it to be smaller.

The pd.read_csv function can help you out with a lot of this and also make the loading of the file a lot faster.

So instead of doing this

quote_df = pd.read_csv(StringIO(str_of_all), sep=',', names=list('ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefg')) #dtype={'A': object, 'B': object, 'C': np.float64}
quote_df.rename(columns={'A':'STK', 'B':'TOpen', 'C':'TPCLOSE', 'D':'TPrice', 'E':'THigh', 'F':'TLow', 'I':'TVol', 'J':'TAmt', 'e':'TDate', 'f':'TTime'}, inplace=True)
quote_df = quote_df.ix[:,[0,3,2,1,4,5,8,9,30,31]]

Do this

columns = ['STK', 'TPrice', 'TPCLOSE', 'TOpen', 'THigh', 'TLow', 'TVol', 'TAmt', 'TDate', 'TTime']
df = pd.read_csv(StringIO(str_of_all), sep=',', usecols=[0,3,2,1,4,5,8,9,30,31])
df.columns = columns

This will only read the columns you are interested in, and name them properly. No need for using the evil .ix object to do magical stuff.

if you use Sql Server

delete from Table where id between 79 and 296

After your edit : you now clarified that you want :

ID (>79 AND < 296)

So use this :

delete from Table where id > 79 and id < 296

This particular error implies that one of the variables being used in the arithmetic on the line has a shape incompatible with another on the same line (i.e., both different and non-scalar). Since n and the output of np.add.reduce() are both scalars, this implies that the problem lies with xm and ym, the two of which are simply your x and y inputs minus their respective means.

Based on this, my guess is that your x and y inputs have different shapes from one another, making them incompatible for element-wise multiplication.

** Technically, it's not that variables on the same line have incompatible shapes. The only problem is when two variables being added, multiplied, etc., have incompatible shapes, whether the variables are temporary (e.g., function output) or not. Two variables with different shapes on the same line are fine as long as something else corrects the issue before the mathematical expression is evaluated.

for OrderedDict() you can access the elements by indexing by getting the tuples of (key,value) pairs as follows or using '.values()'

>>> import collections
>>> d = collections.OrderedDict()
>>> d['foo'] = 'python'
>>> d['bar'] = 'spam'
>>> d.items()
[('foo', 'python'), ('bar', 'spam')]
>>>d.values()
odict_values(['python','spam'])
>>>list(d.values())
['python','spam']

You could use an OrderedDictionary, but I would question why you would want to do that.

It often ends up being easier to load your data into the database, even if it is only to run a quick query. Hard-coded data seems quick to enter, but it quickly becomes a pain if you start having to make changes.

However, if you want to code the names directly into your query, here is a cleaner way to do it:

with names (fname,lname) as (
    values
        ('John','Smith'),
        ('Mary','Jones')
)
select city from user
    inner join names on
        fname=firstName and
        lname=lastName;

The advantage of this is that it separates your data out of the query somewhat.

(This is DB2 syntax; it may need a bit of tweaking on your system).

<input type="hidden" name="item[]" value="[anyvalue]">

Let it be in a repeated mode it will post this element in the form as an array and use the

print_r($_POST['item'])

To retrieve the item

In response to @Zxaos request, since we can not have AND/OR operators for MySQL triggers, starting with your code, below is a complete example to achieve the same.

1. Define the INSERT trigger:

DELIMITER //
DROP TRIGGER IF EXISTS my_insert_trigger//
CREATE DEFINER=root@localhost TRIGGER my_insert_trigger
    AFTER INSERT ON `table`
    FOR EACH ROW

BEGIN
    -- Call the common procedure ran if there is an INSERT or UPDATE on `table`
    -- NEW.id is an example parameter passed to the procedure but is not required
    -- if you do not need to pass anything to your procedure.
    CALL procedure_to_run_processes_due_to_changes_on_table(NEW.id);
END//
DELIMITER ;

2. Define the UPDATE trigger

DELIMITER //
DROP TRIGGER IF EXISTS my_update_trigger//

CREATE DEFINER=root@localhost TRIGGER my_update_trigger
    AFTER UPDATE ON `table`
    FOR EACH ROW
BEGIN
    -- Call the common procedure ran if there is an INSERT or UPDATE on `table`
    CALL procedure_to_run_processes_due_to_changes_on_table(NEW.id);
END//
DELIMITER ;

3. Define the common PROCEDURE used by both these triggers:

DELIMITER //
DROP PROCEDURE IF EXISTS procedure_to_run_processes_due_to_changes_on_table//

CREATE DEFINER=root@localhost PROCEDURE procedure_to_run_processes_due_to_changes_on_table(IN table_row_id VARCHAR(255))
READS SQL DATA
BEGIN

    -- Write your MySQL code to perform when a `table` row is inserted or updated here

END//
DELIMITER ;

You note that I take care to restore the delimiter when I am done with my business defining the triggers and procedure.

Describe Formatted/Extended will show the data definition of the table in hive

As I understand , all of previous answers , does not make an Array output, In my case : I have a model with parent-children structure (simplified code here):

public function parent(){

    return $this->belongsTo('App\Models\Accounting\accounting_coding', 'parent_id');
}


public function children()
{

    return $this->hasMany('App\Models\Accounting\accounting_coding', 'parent_id');
}

and if you want to have all of children IDs as an Array , This approach is fine and working for me :

public function allChildren()
{
    $allChildren = [];
    if ($this->has_branch) {

        foreach ($this->children as $child) {

            $subChildren = $child->allChildren();

            if (count($subChildren) == 1) {
                $allChildren  [] = $subChildren[0];
            } else if (count($subChildren) > 1) {
                $allChildren += $subChildren;
            }
        }
    }
    $allChildren  [] = $this->id;//adds self Id to children Id list

    return $allChildren; 
}

the allChildren() returns , all of childrens as a simple Array .

it is always good to restrict the DOM search. so better to use a parent also, so that the entire DOM won't be traversed.

IT IS VERY FAST

This is a development storage part of Tomas M answer for Chrome. We must add listener

window.addEventListener("storage", (e)=> { console.log(e) } );

Load/save item in storage not runt this event - we MUST trigger it manually by

window.dispatchEvent( new Event('storage') ); // THIS IS IMPORTANT ON CHROME

and now, all open tab-s will receive event

Two generic ways to do the same thing... I'm not aware of any specific open solutions to do this, but it'd be rather trivial to do.

You could write a daily or weekly cron/jenkins job to scrape the previous time period's email from the archive looking for your keyworkds/combinations. Sending a batch digest with what it finds, if anything.

But personally, I'd Setup a specific email account to subscribe to the various security lists you're interested in. Add a simple automated script to parse the new emails for various keywords or combinations of keywords, when it finds a match forward that email on to you/your team. Just be sure to keep the keywords list updated with new products you're using.

You could even do this with a gmail account and custom rules, which is what I currently do, but I have setup an internal inbox in the past with a simple python script to forward emails that were of interest.

print(os.path.join(os.path.dirname(__file__))) 

You can also use this way

if (!/^[0-9]+$/.test('123456askm')) {
  consol.log('Enter Only Number');
} else {
    consol.log('Sucess');
}

If statement is used for checking just one condition quickly. When you have multiple options, use <xsl:choose> as illustrated below:

   <xsl:choose>
     <xsl:when test="$CreatedDate > $IDAppendedDate">
       <h2>mooooooooooooo</h2>
     </xsl:when>
     <xsl:otherwise>
      <h2>dooooooooooooo</h2>
     </xsl:otherwise>
   </xsl:choose>

Also, you can use multiple <xsl:when> tags to express If .. Else If or Switch patterns as illustrated below:

   <xsl:choose>
     <xsl:when test="$CreatedDate > $IDAppendedDate">
       <h2>mooooooooooooo</h2>
     </xsl:when>
     <xsl:when test="$CreatedDate = $IDAppendedDate">
       <h2>booooooooooooo</h2>
     </xsl:when>
     <xsl:otherwise>
      <h2>dooooooooooooo</h2>
     </xsl:otherwise>
   </xsl:choose>

The previous example would be equivalent to the pseudocode below:

   if ($CreatedDate > $IDAppendedDate)
   {
       output: <h2>mooooooooooooo</h2>
   }
   else if ($CreatedDate = $IDAppendedDate)
   {
       output: <h2>booooooooooooo</h2>
   }
   else
   {
       output: <h2>dooooooooooooo</h2>
   }

Try passing width=200 as additional paramater when creating the Label.

This should work in creating label with specified width.

If you want to change it later, you can use:

label.config(width=200)

As you want to change the size of font itself you can try:

label.config(font=("Courier", 44))

Add scrolling="no" attribute to the iframe.

Today I just wrote a post about "Why do we use the letters like “e” in e.preventDefault()?" and I think my answer will make some sense...

At first,let us see the syntax of addEventListener

Normally it will be: target.addEventListener(type, listener[, useCapture]);

And the definition of the parameters of addEventlistener are:

type :A string representing the event type to listen out for.

listener :The object which receives a notification (an object that implements the Event interface) when an event of the specified type occurs. This must be an object implementing the EventListener interface, or a JavaScript function.

(From MDN)

But I think there is one thing should be remarked: When you use Javascript function as the listener, the object that implements the Event interface(object event) will be automatically assigned to the "first parameter" of the function.So,if you use function(e) ,the object will be assigned to "e" because "e" is the only parameter of the function(definitly the first one !),then you can use e.preventDefault to prevent something....

let us try the example as below:

<p>Please click on the checkbox control.</p>
<form>
    <label for="id-checkbox">Checkbox</label>
    <input type="checkbox" id="id-checkbox"/>

    </div>
</form>
<script>
    document.querySelector("#id-checkbox").addEventListener("click", function(e,v){
         //var e=3;
         var v=5;
         var t=e+v;
         console.log(t);
        e.preventDefault();

    }, false);
</script>

the result will be : [object MouseEvent]5 and you will prevent the click event.

but if you remove the comment sign like :

<script>
       document.querySelector("#id-checkbox").addEventListener("click", function(e,v){
            var e=3;
            var v=5;
            var t=e+v;
            console.log(t);
            e.preventDefault();

       }, false);
   </script>

you will get : 8 and an error:"Uncaught TypeError: e.preventDefault is not a function at HTMLInputElement. (VM409:69)".

Certainly,the click event will not be prevented this time.Because the "e" was defined again in the function.

However,if you change the code to:

<script>
       document.querySelector("#id-checkbox").addEventListener("click", function(e,v){
            var e=3;
            var v=5;
            var t=e+v;
            console.log(t);
            event.preventDefault();

       }, false);
   </script>

every thing will work propertly again...you will get 8 and the click event be prevented...

Therefore, "e" is just a parameter of your function and you need an "e" in you function() to receive the "event object" then perform e.preventDefault(). This is also the reason why you can change the "e" to any words that is not reserved by js.

You can set a control variable in vars files located in group_vars/ or directly in hosts file like this:

[vagrant:vars]
test_var=true

[location-1]
192.168.33.10 hostname=apollo

[location-2]
192.168.33.20 hostname=zeus

[vagrant:children]
location-1
location-2

And run tasks like this:

- name: "test"
  command: "echo {{test_var}}"
  when: test_var is defined and test_var

    drawable.mutate()
    drawable.setBounds(0, 0,
            imgWidth,
            imgHeight)
    val start = text.indexOf(atText)
    ssb.setSpan(VerticalImageSpan(drawable), start, start + atText.length, Spannable.SPAN_INCLUSIVE_EXCLUSIVE)
    this.setText(ssb, TextView.BufferType.SPANNABLE)
}

VerticalImageSpan class from great answer https://stackoverflow.com/a/38788432/5381331

Using

val textView = findViewById<TextView>(R.id.textview)
textView.setText("Send an [email-icon] to [email protected].")
textView.addImage("[email-icon]", R.drawable.ic_email,
        resources.getDimensionPixelOffset(R.dimen.dp_30),
        resources.getDimensionPixelOffset(R.dimen.dp_30))

Result

Note
Why VerticalImageSpan class?
ImageSpan.ALIGN_CENTER attribute requires API 29.
Also, after the test, I see that ImageSpan.ALIGN_CENTER only work if the image smaller than the text, if the image bigger than the text then only image is in center, text not center, it align on bottom of image

I just stumbled on a situation where I needed to run a bunch of lines of bash code (not separated with semicolons) from within python. In this scenario the proposed solutions do not help. One approach would be to save a file and then run it with Popen, but it wasn't possible in my situation.

What I ended up doing is something like:

commands = '''
echo "a"
echo "b"
echo "c"
echo "d"
'''

process = subprocess.Popen('/bin/bash', stdin=subprocess.PIPE, stdout=subprocess.PIPE)
out, err = process.communicate(commands)
print out

So I first create the child bash process and after I tell it what to execute. This approach removes the limitations of passing the command directly to the Popen constructor.

Do your databinding and then add the following:

Dim liFirst As New ListItem("", "")
drpList.Items.Insert(0, liFirst)

Could you have multiple local databases? Check your database.yml and make sure you are hitting the pg db that you want. Use rails console to confirm.

Compile all answers in one class. Outputs PIL image.

Check: http://php.net/manual/en/function.mysql-affected-rows.php

you are getting math domain error for either one of the reason : either you are trying to use a negative number inside log function or a zero value.

I was sending "delete" rest request and it failed with 415. I saw what content-type my server uses to hit the api. In my case, It was "application/json" instead of "application/json; charset=utf8".

So ask from your api developer And in the meantime try sending request with content-type= "application/json" only.

There has been many helpful answers here, generally culminating into two points.

1. BACKTICKS(`) are used around identifier names.
2. SINGLE QUOTES(') are used around values.

AND as @MichaelBerkowski said

Backticks are to be used for table and column identifiers, but are only necessary when the identifier is a MySQL reserved keyword, or when the identifier contains whitespace characters or characters beyond a limited set (see below) It is often recommended to avoid using reserved keywords as column or table identifiers when possible, avoiding the quoting issue.

There is a case though where an identifier can neither be a reserved keyword or contain whitespace or characters beyond limited set but necessarily require backticks around them.

EXAMPLE

123E10 is a valid identifier name but also a valid INTEGER literal.

[Without going into detail how you would get such an identifier name], Suppose I want to create a temporary table named 123456e6.

No ERROR on backticks.

DB [XXX]> create temporary table `123456e6` (`id` char (8));
Query OK, 0 rows affected (0.03 sec)

ERROR when not using backticks.

DB [XXX]> create temporary table 123451e6 (`id` char (8));
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near '123451e6 (`id` char (8))' at line 1

However, 123451a6 is a perfectly fine identifier name (without back ticks).

DB [XXX]> create temporary table 123451a6 (`id` char (8));
Query OK, 0 rows affected (0.03 sec)

This is completely because 1234156e6 is also an exponential number.

you can use jquery validator for that but you need to add jquery.validate.js and jquery.form.js file for that. after including validator file define your validation something like this.

<script type="text/javascript">
$(document).ready(function(){
    $("#formID").validate({
    rules :{
        "data[User][name]" : {
            required : true
        }
    },
    messages :{
        "data[User][name]" : {
            required : 'Enter username'
        }
    }
    });
});
</script>

You can see required : true same there is many more property like for email you can define email : true for number number : true

I had this problem in one of my apps, now, I know this is an old thread but here is my solution; I figured out by looking at the data inside the debugger that JVM actually didn't load it properly when Hibernate was trying to update the database (that is actually done in a different thread), so I added the keyword "volatile" to every field of the entities. It has some performance issues to do that but rather that than Heavy objects beeing thrown around...

This code will help you add a MsgBox in your asp.net file. You can change the function definition to your requirements. Hope this helps!

protected void Addstaff_Click(object sender, EventArgs e)    
    {   
 if (intClassCapcity < intCurrentstaffNumber)     
                {                  
            MsgBox("Record cannot be added because max seats available for the " + (string)Session["course_name"] + " training has been reached");    
        }    
else    
    {   
            sqlClassList.Insert();    
    }    
}

private void MsgBox(string sMessage)    
    {    
        string msg = "<script language=\"javascript\">";    
        msg += "alert('" + sMessage + "');";    
        msg += "</script>";    
        Response.Write(msg);    
    }

uint16_t is unsigned 16-bit integer.

unsigned short int is unsigned short integer, but the size is implementation dependent. The standard only says it's at least 16-bit (i.e, minimum value of UINT_MAX is 65535). In practice, it usually is 16-bit, but you can't take that as guaranteed.

Note:

1. If you want a portable unsigned 16-bit integer, use uint16_t.
2. inttypes.h and stdint.h are both introduced in C99. If you are using C89, define your own type.
3. uint16_t may not be provided in certain implementation(See reference below), but unsigned short int is always available.

Reference: C11(ISO/IEC 9899:201x) §7.20 Integer types

For each type described herein that the implementation provides) shall declare that typedef name and define the associated macros. Conversely, for each type described herein that the implementation does not provide, shall not declare that typedef name nor shall it define the associated macros. An implementation shall provide those types described as ‘‘required’’, but need not provide any of the others (described as ‘optional’’).

I'm using the Hadoop Mincemeat module. I think this is a great example to take a note of:

import mincemeat

def mapfn(k,v):
    for w in v:
        yield 'sum',w
        #yield 'count',1


def reducefn(k,v): 
    r1=sum(v)
    r2=len(v)
    print r2
    m=r1/r2
    std=0
    for i in range(r2):
       std+=pow(abs(v[i]-m),2)  
    res=pow((std/r2),0.5)
    return r1,r2,res

Here the generator gets numbers out of a text file (as big as 15GB) and applies simple math on those numbers using Hadoop's map-reduce. If I had not used the yield function, but instead a list comprehension, it would have taken a much longer time calculating the sums and average (not to mention the space complexity).

Hadoop is a great example for using all the advantages of Generators.

SQLDataReaders are forward-only. You're essentially doing this:

count++;  // initially 1
.DataBind(); //consuming all the records

//next iteration on
.Read()
//we've now come to end of resultset, thanks to the DataBind()
//count is still 1 

You could do this instead:

if (reader.HasRows)
{
    rep.DataSource = reader;
    rep.DataBind();
}
int count = rep.Items.Count; //somehow count the num rows/items `rep` has.

If only names of regular files immediately contained within a directory (assume it's ~/dirs) are needed, you can do

find ~/docs -type f -maxdepth 1 > filenames.txt

In my case I ran the following command and it worked (not that I was expecting it to):

sudo pip uninstall pip

Which resulted in:

Uninstalling pip-6.1.1:

In javascript I think that it is not possible, because modern browsers have a policy on security in javascripts.. and clearing the cache is a very violating one.

You can try to add

<META HTTP-EQUIV="Pragma" CONTENT="no-cache">

In your header, but you will have performance loss.

Well, you can modify the value of the counter, but that is obviously a brittle solution. You can load your content via AJAX after you have determined the site is not within a frame - also not a great solution, but it hopefully avoids firing the on beforeunload event (I am assuming).

Edit: Another idea. If you detect you are in a frame, ask the user to disable javascript, before clicking on a link that takes you to the desired URL (passing a querystring that lets your page know to tell the user that they can re-enable javascript once they are there).

Edit 2: Go nuclear - if you detect you are in a frame, just delete your document body content and print some nasty message.

Edit 3: Can you enumerate the top document and set all functions to null (even anonymous ones)?

Try this:

function SelectAnimal() {
    var sel = document.getElementById('Animals');
    var val = document.getElementById('AnimalToFind').value;
    for(var i = 0, j = sel.options.length; i < j; ++i) {
        if(sel.options[i].innerHTML === val) {
           sel.selectedIndex = i;
           break;
        }
    }
}

Clearly this shows the need for a standardized cross-browser const keyword.

But for now:

var myconst = value;

or

Object['myconst'] = value;

Both seem sufficient and anything else is like shooting a fly with a bazooka.

Just use a MaterialButton and the app:backgroundTint and android:textColor attributes:

<MaterialButton
  app:backgroundTint="@color/my_color"
  android:textColor="@android:color/white"/>

int ans = 0;
while (ans == 0) 
{
     for (int i=0; i<3; i++) 
     {
          while ((r = rand5()) == 3){};
          ans += (r < 3) >> i
     }
}

s=" "
seq=["ab", "cd", "ef"]
print(s.join(seq))

ab cd ef

s="."
print(s.join(seq))

ab.cd.ef

Try this, it worked for me. In your terminal: git remote prune origin.

Following many hours of search and testing i found following solution(by implementing different SO solutions) here it what didn't failed in any case i was getting crash.

     Runnable runnable = new Runnable() {
            @Override
            public void run() {

          //displayPopup,progress dialog or what ever action. example

                ProgressDialogBox.setProgressBar(Constants.LOADING,youractivityName.this);
            }};

Where logcat is indicating the crash is happening.. start a runnable .in my case at receiving broadcast.

runOnUiThread(new Runnable() {
            @Override
            public void run() {
                if(!isFinishing()) {
                    new Handler().postAtTime(runnable,2000);
                }
            }
        });

Using lodash:

function createRandomString(length) {_x000D_
        var chars = "abcdefghijklmnopqrstufwxyzABCDEFGHIJKLMNOPQRSTUFWXYZ1234567890"_x000D_
        var pwd = _.sampleSize(chars, length || 12)  // lodash v4: use _.sampleSize_x000D_
        return pwd.join("")_x000D_
    }_x000D_
document.write(createRandomString(8))

<script src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.11/lodash.min.js"></script>

It's simple. On the sender side, use Intent.putExtra:

Intent myIntent = new Intent(A.this, B.class);
myIntent.putExtra("intVariableName", intValue);
startActivity(myIntent);

On the receiver side, use Intent.getIntExtra:

 Intent mIntent = getIntent();
 int intValue = mIntent.getIntExtra("intVariableName", 0);

login to your server via

ssh -X root@yourIP

edit /etc/ssh/sshd_config file, and add this line to it.

X11UseLocalhost no

Restart sshd. for CentOS (check your distribution)

/sbin/service sshd restart

check your DISPLAY

echo $DISPLAY

you should see this

yourIP:10.0

Enjoy

firefox

I find it very clean to use the internal variable "$SECONDS"

SECONDS=0 ; sleep 10 ; echo $SECONDS

$new_website = substr($str, ($pos = strrpos($str, '//')) !== false ? $pos + 2 : 0); 

This would remove everything before the '//'.

EDIT

This one is tested. Using strrpos() instead or strpos().

Try changing it to.

 Response.Clear();
 Response.ClearHeaders();
 Response.ClearContent();
 Response.AddHeader("Content-Disposition", "attachment; filename=" + file.Name);
 Response.AddHeader("Content-Length", file.Length.ToString());
 Response.ContentType = "text/plain";
 Response.Flush();
 Response.TransmitFile(file.FullName);
 Response.End();

If the width of the other column is fixed, how about using the calc CSS function working for all common browsers:

width: calc(100% - 20px) /* 20px being the first column's width */

This way the width of the second row will be calculated (i.e. remaining width) and applied responsively.

You can't stop a timer function mid-execution. You can only catch it after it completes and prevent it from triggering again.

You can do so starting with Postgres 9.1:

with rows as (
INSERT INTO Table1 (name) VALUES ('a_title') RETURNING id
)
INSERT INTO Table2 (val)
SELECT id
FROM rows

In the meanwhile, if you're only interested in the id, you can do so with a trigger:

create function t1_ins_into_t2()
  returns trigger
as $$
begin
  insert into table2 (val) values (new.id);
  return new;
end;
$$ language plpgsql;

create trigger t1_ins_into_t2
  after insert on table1
for each row
execute procedure t1_ins_into_t2();

How about this?

fscanf(file,"%d %d %d %d %d %d %d",&line1_1,&line1_2, &line1_3, &line2_1, &line2_2, &line3_1, &line3_2); 

In this case spaces in fscanf match multiple occurrences of any whitespace until the next token in found.

You should create an installer, as mentioned before. Even though it is also possible to let py2exe bundle everything into a single executable, by setting bundle_files option to 1 and the zipfile keyword argument to None, I don't recommend this for PyGTK applications.

That's because of GTK+ tries to load its data files (locals, themes, etc.) from the directory it was loaded from. So you have to make sure that the directory of your executable contains also the libraries used by GTK+ and the directories lib, share and etc from your installation of GTK+. Otherwise you will get problems running your application on a machine where GTK+ is not installed system-wide.

For more details read my guide to py2exe for PyGTK applications. It also explains how to bundle everything, but GTK+.

One way that you can do it is creating a new object in the module instead of replacing it.

for example:

var testone = function () {
    console.log('test one');
};
var testTwo = function () {
    console.log('test two');
};
module.exports.testOne = testOne;
module.exports.testTwo = testTwo;

and to call

var test = require('path_to_file').testOne:
testOne();

Inline elements:

1. respect left & right margins and padding, but not top & bottom
2. cannot have a width and height set
3. allow other elements to sit to their left and right.
4. see very important side notes on this here.

Block elements:

1. respect all of those
2. force a line break after the block element
3. acquires full-width if width not defined

Inline-block elements:

1. allow other elements to sit to their left and right
2. respect top & bottom margins and padding
3. respect height and width

From W3Schools:

• An inline element has no line break before or after it, and it tolerates HTML elements next to it.

• A block element has some whitespace above and below it and does not tolerate any HTML elements next to it.

• An inline-block element is placed as an inline element (on the same line as adjacent content), but it behaves as a block element.

When you visualize this, it looks like this:

The image is taken from this page, which also talks some more about this subject.

If you are installing into local repository, there is no special index/cache update needed.

Make sure that:

1. You have installed the first artifact in your local repository properly. Simply copying the file to .m2 may not work as expected. Make sure you install it by mvn install

2. The dependency in 2nd project is setup correctly. Check on any typo in groupId/artifactId/version, or unmatched artifact type/classifier.

I'm assuming that you are using React-Router V4, as you used the same in the original Sandbox Link.

You are rendering the Main component in the call to ReactDOM.render that renders a Link and Main component is outside of Router, that's why it is throwing the error:

You should not use <Link> outside a <Router>

Changes:

1. Use any one of these Routers, BrowserRouter/HashRouter etc..., because you are using React-Router V4.

2. Router can have only one child, so wrap all the routes in a div or Switch.

3. React-Router V4, doesn't have the concept of nested routes, if you wants to use nested routes then define those routes directly inside that component.

Check this working example with each of these changes.

Parent Component:

const App = () => (
  <BrowserRouter>
    <div className="sans-serif">
      <Route path="/" component={Main} />
      <Route path="/view/:postId" component={Single} />
    </div>
  </BrowserRouter>
);

render(<App />, document.getElementById('root'));

Main component from route

import React from 'react';
import { Link } from 'react-router-dom';

export default () => (
  <div>
    <h1>
      <Link to="/">Redux example</Link>
    </h1>
  </div>
)

Etc.

Also check this answer: Nested routes with react router v4

I was also having syntax error: unexpected token < while posting a form via ajax. Then I used curl to see what it returns:

curl -X POST --data "firstName=a&lastName=a&[email protected]&pass=aaaa&mobile=12345678901&nID=123456789123456789&age=22&prof=xfd" http://handymama.co/CustomerRegistration.php

I got something like this as a response:

<br />
<b>Warning</b>:  Cannot modify header information - headers already sent by (output started at /home/handymama/public_html/CustomerRegistration.php:1) in <b>/home/handymama/public_html/CustomerRegistration.php</b> on line <b>3</b><br />
<br />

<b>Warning</b>:  Cannot modify header information - headers already sent by (output started at /home/handymama/public_html/CustomerRegistration.php:1) in <b>/home/handymama/public_html/CustomerRegistration.php</b> on line <b>8</b><br />

So all I had to do is just change the log level to only errors rather than warning.

error_reporting(E_ERROR);

A tool to use here is awk:

cat file | awk 'BEGIN{ found=0} /TERMINATE/{found=1}  {if (found) print }'

How does this work:

1. We set the variable 'found' to zero, evaluating false
2. if a match for 'TERMINATE' is found with the regular expression, we set it to one.
3. If our 'found' variable evaluates to True, print :)

The other solutions might consume a lot of memory if you use them on very large files.

Update the master branch, which you need to do regardless.

Then, one of:

1. Rebase the old branch against the master branch. Solve the merge conflicts during rebase, and the result will be an up-to-date branch that merges cleanly against master.

2. Merge your branch into master, and resolve the merge conflicts.

3. Merge master into your branch, and resolve the merge conflicts. Then, merging from your branch into master should be clean.

None of these is better than the other, they just have different trade-off patterns.

I would use the rebase approach, which gives cleaner overall results to later readers, in my opinion, but that is nothing aside from personal taste.

To rebase and keep the branch you would:

git checkout <branch> && git rebase <target>

In your case, check out the old branch, then

git rebase master 

to get it rebuilt against master.

Here's a zsh-only function that I like for its compactness. It uses the ‘A’ expansion modifier — see zshexpn(1).

realpath() { for f in "$@"; do echo ${f}(:A); done }

For other types, check out the types module:

>>> import types
>>> x = "mystring"
>>> isinstance(x, types.StringType)
True
>>> x = 5
>>> isinstance(x, types.IntType)
True
>>> x = None
>>> isinstance(x, types.NoneType)
True

P.S. Typechecking is a bad idea.

To point out what I had to dig out of Chris Johansen's chat with OP (linked from a reply to an answer):

git add vendor/plugins/open_flash_chart_2 # will add gitlink, content will stay untracked

git add vendor/plugins/open_flash_chart_2/ # NOTICE THE SLASH!!!!

The second form will add it without gitlink, and the contents are trackable. The .git dir is conveniently & automatically ignored. Thank you Chris!

No.

JSON is purely meant to be a data description language. As noted on http://www.json.org, it is a "lightweight data-interchange format." - not a programming language.

Per http://en.wikipedia.org/wiki/JSON, the "basic types" supported are:

• Number (integer, real, or floating point)
• String (double-quoted Unicode with backslash escaping)
• Boolean (true and false)
• Array (an ordered sequence of values, comma-separated and enclosed in square brackets)
• Object (collection of key:value pairs, comma-separated and enclosed in curly braces)
• null

UPDATE: As TimK pointed out, this isn't needed with jquery 1.5.2 any more. But if you want to add custom headers or allow the use of credentials (username, password, or cookies, etc), read on.

I think I found the answer! (4 hours and a lot of cursing later)

//This does not work!!
Access-Control-Allow-Headers: *

You need to manually specify all the headers you will accept (at least that was the case for me in FF 4.0 & Chrome 10.0.648.204).

jQuery's $.ajax method sends the "x-requested-with" header for all cross domain requests (i think its only cross domain).

So the missing header needed to respond to the OPTIONS request is:

//no longer needed as of jquery 1.5.2
Access-Control-Allow-Headers: x-requested-with

If you are passing any non "simple" headers, you will need to include them in your list (i send one more):

//only need part of this for my custom header
Access-Control-Allow-Headers: x-requested-with, x-requested-by

So to put it all together, here is my PHP:

// * wont work in FF w/ Allow-Credentials
//if you dont need Allow-Credentials, * seems to work
header('Access-Control-Allow-Origin: http://www.example.com');
//if you need cookies or login etc
header('Access-Control-Allow-Credentials: true');
if ($this->getRequestMethod() == 'OPTIONS')
{
  header('Access-Control-Allow-Methods: GET, POST, PUT, DELETE, OPTIONS');
  header('Access-Control-Max-Age: 604800');
  //if you need special headers
  header('Access-Control-Allow-Headers: x-requested-with');
  exit(0);
}

Yes, they can throw exceptions. If so, they will only be partially initialized and if non-final, subject to attack.

The following is from the Secure Coding Guidelines 2.0.

Partially initialized instances of a non-final class can be accessed via a finalizer attack. The attacker overrides the protected finalize method in a subclass, and attempts to create a new instance of that subclass. This attempt fails (in the above example, the SecurityManager check in ClassLoader's constructor throws a security exception), but the attacker simply ignores any exception and waits for the virtual machine to perform finalization on the partially initialized object. When that occurs the malicious finalize method implementation is invoked, giving the attacker access to this, a reference to the object being finalized. Although the object is only partially initialized, the attacker can still invoke methods on it (thereby circumventing the SecurityManager check).

NSString *str = @"helowrld";
// This converts the string to an NSData object
NSData *data = [str dataUsingEncoding:NSUTF8StringEncoding];

you can take reference from this link

$("#div_element").load('script.php');

demo: http://sandbox.phpcode.eu/g/2ecbe/3

whole code:

<div id="submit">ajax</div> 
<div id="div_element"></div> 
<script> 
$('#submit').click(function(event){ 
   $("#div_element").load('script.php?html=some_arguments');  

}); 
</script> 

As per my analysis and search on the internet also, I could not found a way to centre the image vertically centred using <div> it was possible only using <table> because table provides the following property:

valign="middle"

Suppose you have a hidden input, named XXX, if you want to assign a value to the following

<script type="text/javascript">

    $(document).ready(function(){
    $('#XXX').val('any value');
    })
</script>

Type 'q' and it will do the job.

Whenever you are at the terminal and have a similar predicament keep in mind also to try and type 'quit', 'exit' as well as the abort key combination 'Ctrl + C'.

A GridView is a ViewGroup that displays items in two-dimensional scrolling grid. The items in the grid come from the ListAdapter associated with this view.

This is what you'd want to use (keep using). Because a GridView gets its data from a ListAdapter, the only data loaded in memory will be the one displayed on screen. GridViews, much like ListViews reuse and recycle their views for better performance.

Whereas a GridLayout is a layout that places its children in a rectangular grid.

It was introduced in API level 14, and was recently backported in the Support Library. Its main purpose is to solve alignment and performance problems in other layouts. Check out this tutorial if you want to learn more about GridLayout.

I just have the same problem, just open the task manager, go to services tab and search MySQL_One service, rigth click and start, this works for very good.

for k, v := range m { 
    fmt.Printf("key[%s] value[%s]\n", k, v)
}

or

for k := range m {
    fmt.Printf("key[%s] value[%s]\n", k, m[k])
}

Go language specs for for statements specifies that the first value is the key, the second variable is the value, but doesn't have to be present.

trick string to boolean conversion in javascript. e.g.

var bool= "true";
console.log(bool==true) //false

var bool_con = JSON.parse(bool);

console.log(bool_con==true) //true
