You can disable DHE completely in your jdk, edit jre/lib/security/java.security and make sure DHE is disabled, eg. like

jdk.tls.disabledAlgorithms=SSLv3, DHE.

I haven't done any benchmarks, but this recipe "works for me".

The short version: use '%x' % val, then unhexlify the result. The devil is in the details, though, as unhexlify requires an even number of hex digits, which %x doesn't guarantee. See the docstring, and the liberal inline comments for details.

from binascii import unhexlify

    """
    Use :ref:`string formatting` and :func:`~binascii.unhexlify` to
    convert ``val``, a :func:`long`, to a byte :func:`str`.

    :param long val: The value to pack

      big-endian, ``'little'`` for little-endian.

    # one (1) hex digit per four (4) bits
    width = val.bit_length()

    # want more digits than we need (hence the ternary-ish 'or')
    width += 8 - ((width % 8) or 8)

    # format width specifier: four (4) bits per hex digit
    fmt = '%%0%dx' % (width // 4)

    # prepend zero (0) to the width, to zero-pad the output

Casting should be enough. If you're using C# 3.0 you can make a handy extension method to parse enum values:

public static TEnum ToEnum<TInput, TEnum>(this TInput value)
{
    Type type = typeof(TEnum);

    if (value == default(TInput))
    {
        throw new ArgumentException("Value is null or empty.", "value");
    }

    if (!type.IsEnum)
    {
        throw new ArgumentException("Enum expected.", "TEnum");
    }

    return (TEnum)Enum.Parse(type, value.ToString(), true);
}

It also has something to do with the version of JDK. If it does well in JDK6, maybe it will have the problem in JDK 7 described by you, because the implementation method in jdk 7 has been changed.

Look at this:

Description: The sorting algorithm used by java.util.Arrays.sort and (indirectly) by java.util.Collections.sort has been replaced. The new sort implementation may throw an IllegalArgumentException if it detects a Comparable that violates the Comparable contract. The previous implementation silently ignored such a situation. If the previous behavior is desired, you can use the new system property, java.util.Arrays.useLegacyMergeSort, to restore previous mergesort behaviour.

I don't know the exact reason. However, if you add the code before you use sort. It will be OK.

System.setProperty("java.util.Arrays.useLegacyMergeSort", "true");

While adding cache-buster parameters to make the request look different seems like a solid solution, I would advise against it, as it would hurt any application that relies on actual caching taking place. Making the APIs output the correct headers is the best possible solution, even if that's slightly more difficult than adding cache busters to the callers.

To the database, they end up being the same. For you, though, you'll have to use that second syntax in some situations. For the sake of editing queries that end up having to use it (finding out you needed a left join where you had a straight join), and for consistency, I'd pattern only on the 2nd method. It'll make reading queries easier.

Simple implementantion in javascript

function sizeOfBase64String(base64String) {
    if (!base64String) return 0;
    const padding = (base64String.match(/(=*)$/) || [])[1].length;
    return 4 * Math.ceil((base64String.length / 3)) - padding;
}

 for(int i=0;i<ytFiles.size();i++){

                    int key = ytFiles.keyAt(i);
                    Log.e("key", String.valueOf(key));
                    String format = ytFiles.get(key).getFormat().toString();
                    String url = ytFiles.get(key).getUrl();
                    Log.e("url",url);
                }

you can get key by method keyat and you have to pass the index then it will return key at that particular index. this loop will get all the key

A submodule is its own repo/work-area, with its own .git directory.

So, first commit/push your submodule's changes:

$ cd path/to/submodule
$ git add <stuff>
$ git commit -m "comment"
$ git push

Then, update your main project to track the updated version of the submodule:

$ cd /main/project
$ git add path/to/submodule
$ git commit -m "updated my submodule"
$ git push

In the specific case of Wicket: This is the very reason why I asked the Wicket devs to add support for an explicit two phase component initialization process in the framework's lifecycle of constructing a component i.e.

1. Construction - via constructor
2. Initialization - via onInitilize (after construction when virtual methods work!)

There was quite an active debate about whether it was necessary or not (it fully is necessary IMHO) as this link demonstrates http://apache-wicket.1842946.n4.nabble.com/VOTE-WICKET-3218-Component-onInitialize-is-broken-for-Pages-td3341090i20.html)

The good news is that the excellent devs at Wicket did end up introducing two phase initialization (to make the most aweseome Java UI framework even more awesome!) so with Wicket you can do all your post construction initialization in the onInitialize method that is called by the framework automatically if you override it - at this point in the lifecycle of your component its constructor has completed its work so virtual methods work as expected.

I'm giving this example because this actually work for my use case.

I was trying to use the AWS Rekognition API. The API returns a BoundingBox object:

BoundingBox boundingBox = faceDetail.getBoundingBox();

The code below uses it to crop the image:

import com.amazonaws.services.rekognition.model.BoundingBox;

private BufferedImage cropImage(BufferedImage image, BoundingBox box) {
        Rectangle goal = new Rectangle(Math.round(box.getLeft()* image.getWidth()),Math.round(box.getTop()* image.getHeight()),Math.round(box.getWidth() * image.getWidth()), Math.round(box.getHeight() * image.getHeight()));

        Rectangle clip = goal.intersection(new Rectangle(image.getWidth(), image.getHeight()));

        BufferedImage clippedImg = image.getSubimage(clip.x, clip.y , clip.width, clip.height);

        return clippedImg;
    }

Hope it helps!!

In MySQL, @variable indicates a user-defined variable. You can define your own.

SET @a = 'test';
SELECT @a;

Outside of stored programs, a variable, without @, is a system variable, which you cannot define yourself.

The scope of this variable is the entire session. That means that while your connection with the database exists, the variable can still be used.

This is in contrast with MSSQL, where the variable will only be available in the current batch of queries (stored procedure, script, or otherwise). It will not be available in a different batch in the same session.

Not the most readable solution, but you can mix the result from a value-of with plain text:

<a>
  <xsl:attribute name="href"> 
    Text<xsl:value-of select="/*/properties/property[@name='report']/@value"/>Text
  </xsl:attribute>
</a>

I was able to use Joey's Answer to create a function:

Use it as:

@echo off
SETLOCAL ENABLEDELAYEDEXPANSION

SET "MYTEXT=jump over the chair"
echo !MYTEXT!
call:ReplaceText "!MYTEXT!" chair table RESULT
echo !RESULT!

GOTO:EOF

And these Functions to the bottom of your Batch File.

:FUNCTIONS
@REM FUNCTIONS AREA
GOTO:EOF
EXIT /B

:ReplaceText
::Replace Text In String
::USE:
:: CALL:ReplaceText "!OrginalText!" OldWordToReplace NewWordToUse  Result
::Example
::SET "MYTEXT=jump over the chair"
::  echo !MYTEXT!
::  call:ReplaceText "!MYTEXT!" chair table RESULT
::  echo !RESULT!
::
:: Remember to use the "! on the input text, but NOT on the Output text.
:: The Following is Wrong: "!MYTEXT!" !chair! !table! !RESULT!
:: ^^Because it has a ! around the chair table and RESULT
:: Remember to add quotes "" around the MYTEXT Variable when calling.
:: If you don't add quotes, it won't treat it as a single string
::
set "OrginalText=%~1"
set "OldWord=%~2"
set "NewWord=%~3"
call set OrginalText=%%OrginalText:!OldWord!=!NewWord!%%
SET %4=!OrginalText!
GOTO:EOF

And remember you MUST add "SETLOCAL ENABLEDELAYEDEXPANSION" to the top of your batch file or else none of this will work properly.

SETLOCAL ENABLEDELAYEDEXPANSION
@REM # Remember to add this to the top of your batch file.

Try this:

CREATE FUNCTION dbo.FnDAYSADDNOWK(
          @addDate AS DATE, 
          @numDays AS INT
       ) RETURNS DATETIME AS

    BEGIN
    WHILE @numDays > 0 BEGIN
        SET @addDate = DATEADD(day, 1, @addDate)    
        IF DATENAME(DW, @addDate) <> 'sunday' BEGIN
            SET @numDays = @numDays - 1 
        END
    END

    RETURN CAST(@addDate AS DATETIME)
END

What means about isKindOfClass in Apple Documentation

Be careful when using this method on objects represented by a class cluster. Because of the nature of class clusters, the object you get back may not always be the type you expected. If you call a method that returns a class cluster, the exact type returned by the method is the best indicator of what you can do with that object. For example, if a method returns a pointer to an NSArray object, you should not use this method to see if the array is mutable, as shown in the following code:

// DO NOT DO THIS!
if ([myArray isKindOfClass:[NSMutableArray class]])
{
    // Modify the object
}

If you use such constructs in your code, you might think it is alright to modify an object that in reality should not be modified. Doing so might then create problems for other code that expected the object to remain unchanged.

You can not mix vb and c# within the same project - if you notice in visual studio the project files are either .vbproj or .csproj. You can within a solution - have 1 proj in vb and 1 in c#.

Looks like according to this you can potentially use them both in a web project in the App_Code directory:

requirement for tkinter:

python 3.6+

and go to shell write the test code like :

from tkinter import *

root = Tk()

root.mainloop()

Well, I'm sure that you didn't set the models yet, so what dose it migrate now ??

So the solution is setting all variables and set Charfield, Textfield....... and migrate them and it will work.

Probably late but here is a plugin that can do the job : http://multi-level-push-menu.make.rs/

void mean that you won't be returning any value form the function or method

I literally just wanted the first row of my data which are the headers I need and didn't want to iterate over all my data to get them, so I just did this:

with open(data, 'r', newline='') as csvfile:
t = 0
for i in csv.reader(csvfile, delimiter=',', quotechar='|'):
    if t > 0:
        break
    else:
        dbh = i
        t += 1

In the event that you already have a class and need to alternate between classes as oppose to add a class, you can chain toggle events:

$('li.multi').click(function(e) {
    $(this).toggleClass('opened').toggleClass('multi-opened');
});

I am guessing you're confused with the parameterization of the types:

// This works, because there is one class/type definition in the parameterized <> field
ArrayList<String> myArrayList = new ArrayList<String>(); 


// This doesn't work, as you cannot use primitive types here
ArrayList<char> myArrayList = new ArrayList<char>();

If you are using a map() operator on your response,you could maybe chain a toArray() operator to it...then you should be able to iterate through newly created array...at least that worked for me :)

If no table with such name exists, DROP fails with error while DROP IF EXISTS just does nothing.

This is useful if you create/modifi your database with a script; this way you do not have to ensure manually that previous versions of the table are deleted. You just do a DROP IF EXISTS and forget about it.

Of course, your current DB engine may not support this option, it is hard to tell more about the error with the information you provide.

I asume you have connected to your database already.

$sql = "SELECT * FROM my_table";
$result = mysql_query($sql);

$row = 1; // 1-based index
while($row_data = mysql_fetch_assoc($result)) {
    $col = 0;
    foreach($row_data as $key=>$value) {
        $objPHPExcel->getActiveSheet()->setCellValueByColumnAndRow($col, $row, $value);
        $col++;
    }
    $row++;
}

That doesn't work because distToPoint is inside your class, so you need to prefix it with the classname if you want to refer to it, like this: classname.distToPoint(self, p). You shouldn't do it like that, though. A better way to do it is to refer to the method directly through the class instance (which is the first argument of a class method), like so: self.distToPoint(p).

if only 1 row, you can use join

Select t1.Col1, t1.Col2, t1.Col3, t2.Col4, t2.Col5 from Table1 t1 join Table2 t2;

select ROUND(CASE 

WHEN  CONVERT( float, REPLACE( isnull( value1,''),',',''))='' AND CONVERT( float, REPLACE( isnull( value2,''),',',''))='' then  CONVERT( float, REPLACE( isnull( value3,''),',',''))

WHEN  CONVERT( float, REPLACE( isnull( value1,''),',',''))='' AND CONVERT( float, REPLACE( isnull( value2,''),',',''))!='' then  CONVERT( float, REPLACE( isnull( value3,''),',',''))

WHEN  CONVERT( float, REPLACE( isnull( value1,''),',',''))!='' AND CONVERT( float, REPLACE( isnull( value2,''),',',''))='' then  CONVERT( float, REPLACE( isnull( value3,''),',',''))

else CONVERT( float, REPLACE(isnull( value1,''),',','')) end,0)  from Tablename where    ID="123"

This code is a very good example for a dynamic column with a cursor, since you cannot use '+' in @STATEMENT:

    DECLARE @inputList NVARCHAR(4000) = ''

    DECLARE @my_cur CURSOR
    EXECUTE SP_EXECUTESQL
        N'SET @my_cur = CURSOR FAST_FORWARD FOR
            SELECT
                CASE @field
                    WHEN ''fn'' then fn
                    WHEN ''n_family_name'' then n_family_name
                END
            FROM
                dbo.vCard
            WHERE
                CASE @field
                    WHEN ''fn'' then fn
                    WHEN ''n_family_name'' then n_family_name
                END
                LIKE ''%''+@query+''%'';
            OPEN @my_cur;',
        N'@field sysname, @query NVARCHAR(4000), @my_cur CURSOR OUTPUT',
        @field = @field,
        @query = @query,
        @my_cur = @my_cur OUTPUT
    FETCH NEXT FROM @my_cur INTO @inputList
    WHILE @@FETCH_STATUS = 0
    BEGIN
        PRINT @inputList
        FETCH NEXT FROM @my_cur INTO @inputList
    END
    RETURN

The (un)safe way to do this - if you are ok with not using option explicit - is...

Not TypeName(myObj) = "Empty"

This also handles the case if the object has not been declared. This is useful if you want to just comment out a declaration to switch off some behaviour...

Dim myObj as Object
Not TypeName(myObj) = "Empty"  '/ true, the object exists - TypeName is Object

'Dim myObj as Object
Not TypeName(myObj) = "Empty"  '/ false, the object has not been declared

This works because VBA will auto-instantiate an undeclared variable as an Empty Variant type. It eliminates the need for an auxiliary Boolean to manage the behaviour.

I use Mock (which is now unittest.mock on py3.3+) for this:

from mock import patch
from PyQt4 import Qt


@patch.object(Qt.QMessageBox, 'aboutQt')
def testShowAboutQt(self, mock):
    self.win.actionAboutQt.trigger()
    self.assertTrue(mock.called)

For your case, it could look like this:

import mock
from mock import patch


def testClearWasCalled(self):
   aw = aps.Request("nv1")
   with patch.object(aw, 'Clear') as mock:
       aw2 = aps.Request("nv2", aw)

   mock.assert_called_with(42) # or mock.assert_called_once_with(42)

Mock supports quite a few useful features, including ways to patch an object or module, as well as checking that the right thing was called, etc etc.

Caveat emptor! (Buyer beware!)

If you mistype assert_called_with (to assert_called_once or assert_called_wiht) your test may still run, as Mock will think this is a mocked function and happily go along, unless you use autospec=true. For more info read assert_called_once: Threat or Menace.

set print elements 0

From the GDB manual:

set print elements number-of-elements

Set a limit on how many elements of an array GDB will print. If GDB is printing a large array, it stops printing after it has printed the number of elements set by the set print elements command. This limit also applies to the display of strings. When GDB starts, this limit is set to 200. Setting number-of-elements to zero means that the printing is unlimited.

Wouldn't it be better to not use any dynamic types for this, and let your class implement an interface. Then, you can check at runtime wether an object implements that interface, and thus, has the expected method (or property).

public interface IMyInterface
{
   void Somemethod();
}


IMyInterface x = anyObject as IMyInterface;
if( x != null )
{
   x.Somemethod();
}

I think this is the only correct way.

The thing you're referring to is duck-typing, which is useful in scenarios where you already know that the object has the method, but the compiler cannot check for that. This is useful in COM interop scenarios for instance. (check this article)

If you want to combine duck-typing with reflection for instance, then I think you're missing the goal of duck-typing.

                         )
            );
       xmlNode.Save("Tushar.xml");

Supposedly this way of coding should be easier, as the code closely resembles the output (which Jon's example above does not). However, I found that while coding this relatively easy example I was prone to lose my way between the cartload of comma's that you have to navigate among. Visual studio's auto spacing of code does not help either.

None of the solutions out there worked for me. What I eventually discovered was the following combination:

• Client system: Windows XP Pro SP3
• Client system has .NET Framework 2 SP1, 3, 3.5 installed
• Software targeting .NET 2 using classic web services (.asmx)
• Server: IIS6
• Web site "Secure Communications" set to:
  • Require Secure Channel
  • Accept client certificates

Apparently, it was this last option that was causing the issue. I discovered this by trying to open the web service URL directly in Internet Explorer. It just hung indefinitely trying to load the page. Disabling "Accept client certificates" allowed the page to load normally. I am not sure if it was a problem with this specific system (maybe a glitched client certificate?) Since I wasn't using client certificates this option worked for me.

For me, the simplest way to use ALIAS in WHERE class is to create a subquery and select from it instead.

Example:

WITH Q1 AS (
    SELECT LENGTH(name) AS name_length,
    id,
    name
    FROM any_table
)

SELECT id, name, name_length form Q1 where name_length > 0

You will clearly see that:

System is a class in the java.lang package.

out is a static member of the System class, and is an instance of java.io.PrintStream.

println is a method of java.io.PrintStream. This method is overloaded to print message to output destination, which is typically a console or file.

1. Make sure you can run powershell scripts (it is disabled by default). Likely you have already done this. http://technet.microsoft.com/en-us/library/ee176949.aspx

   Set-ExecutionPolicy RemoteSigned
   

2. Run this python script on your powershell script helloworld.py:

   # -*- coding: iso-8859-1 -*-
   import subprocess, sys
   
   p = subprocess.Popen(["powershell.exe", 
                 "C:\\Users\\USER\\Desktop\\helloworld.ps1"], 
                 stdout=sys.stdout)
   p.communicate()
   

This code is based on python3.4 (or any 3.x series interpreter), though it should work on python2.x series as well.

try

date.innerHTML= date.innerHTML.replace(/^(..)\//,'<span>$1</span></br>')

this is a basic step for learn:

import os, stat, sys
import time

dirpath = sys.argv[1] if len(sys.argv) == 2 else r'.'

listdir = os.listdir(dirpath)

for i in listdir:
    os.chdir(dirpath)
    data_001 = os.path.realpath(i)
    listdir_stat1 = os.stat(data_001)
    listdir_stat2 = ((os.stat(data_001), data_001))
    print time.ctime(listdir_stat1.st_ctime), data_001

If you are reusing an element over and over (A bootstrap modal dialog in my case), then calling ko.applyBindings(el) multiple times will cause this problem.

Instead just do it once like this:

if (!applied) {
    ko.applyBindings(el);
    applied = true;
}

Or like this:

var apply = function (viewModel, containerElement) {
    ko.applyBindings(viewModel, containerElement);
    apply = function() {}; // only allow this function to be called once.
}

PS: This might happen more often to you if you use the mapping plugin and convert your JSON data to observables.

In some cases you may not be able to suspend, or for that matter take any of the "Power" actions on the VM. You may also already have multiple VMs up and running. Use this process to identify the correct PID to kill.

On Windows 7 - Open Task Manager - Look for processes with the name, "vmware-vmx.exe", note the PIDs.

Switch to the Performance tab and start the "Resource Monitor". Expand the "Disk Activity" panel. Sort the "File" column. Look for the appropriate vmdk file for the VM you want to kill. The "Image" column will have the "vmware-vmx" process listed. Note the PID.

Switch back to the "Processes" tab and kill the PID.

JavaScript is a client-side language and your MySQL database is going to be running on a server.

So you have to rename your file to index.php for example (.php is important) so you can use php code for that. It is not very difficult, but not directly possible with html.

(Somehow you can tell your server to let the html files behave like php files, but this is not the best solution.)

So after you renamed your file, go to the very top, before <html> or <!DOCTYPE html> and type:

<?php
    if($_SERVER['REQUEST_METHOD'] == 'POST') {
        /*Creating variables*/
        $name = $_POST["name"];
        $address = $_POST["address"];
        $age = $_POST["age"];


        $dbhost = "localhost"; /*most of the time it's localhost*/
        $username = "yourusername";
        $password = "yourpassword";
        $dbname = "mydatabase";

        $mysql = mysqli_connect($dbhost, $username, $password, $dbname); //It connects
        $query = "INSERT INTO yourtable (name,address,age) VALUES $name, $address, $age";
        mysqli_query($mysql, $query);
    }
?>
<!DOCTYPE html>
<html>
<head>.......
....
    <form method="post">
        <input name="name" type="text"/>
        <input name="address" type="text"/>
        <input name="age" type="text"/>
    </form>
....

You can do exactly that via the various sizeWithFont: methods in NSString UIKit Additions. In your case the simplest variant should suffice (since you don't have multi-line labels):

NSString *someString = @"Hello World";
UIFont *yourFont = // [UIFont ...]
CGSize stringBoundingBox = [someString sizeWithFont:yourFont];

There are several variations of this method, eg. some consider line break modes or maximum sizes.

Although you can not set the default date format for a single database, you can change the default language for a login which is used to access this database:

ALTER LOGIN your_login WITH DEFAULT_LANGUAGE=British

In some cases it helps.

The easiest way is to use the library commands

import commands
print commands.getstatusoutput('echo "test" | wc')

OS X uses a mix of BSD and GNU tools, so best always check the documentation (although I had it that less didn't even conform to the OS X manpage):

https://web.archive.org/web/20170808213955/https://developer.apple.com/legacy/library/documentation/Darwin/Reference/ManPages/man1/sed.1.html

sed takes the argument after -i as the extension for backups. Provide an empty string (-i '') for no backups.

The following should do:

LC_ALL=C find . -type f -name '*.txt' -exec sed -i '' s/this/that/ {} +

The -type f is just good practice; sed will complain if you give it a directory or so. -exec is preferred over xargs; you needn't bother with -print0 or anything. The {} + at the end means that find will append all results as arguments to one instance of the called command, instead of re-running it for each result. (One exception is when the maximal number of command-line arguments allowed by the OS is breached; in that case find will run more than one instance.)

It seems you don't import jquery. Those $ functions come with this non standard (but very useful) library.

Read the tutorial there : http://docs.jquery.com/Tutorials:Getting_Started_with_jQuery It starts with how to import the library.

The output of EXPLAIN PLAN is a debug output from Oracle's query optimiser. The COST is the final output of the Cost-based optimiser (CBO), the purpose of which is to select which of the many different possible plans should be used to run the query. The CBO calculates a relative Cost for each plan, then picks the plan with the lowest cost.

(Note: in some cases the CBO does not have enough time to evaluate every possible plan; in these cases it just picks the plan with the lowest cost found so far)

In general, one of the biggest contributors to a slow query is the number of rows read to service the query (blocks, to be more precise), so the cost will be based in part on the number of rows the optimiser estimates will need to be read.

For example, lets say you have the following query:

SELECT emp_id FROM employees WHERE months_of_service = 6;

(The months_of_service column has a NOT NULL constraint on it and an ordinary index on it.)

There are two basic plans the optimiser might choose here:

• Plan 1: Read all the rows from the "employees" table, for each, check if the predicate is true (months_of_service=6).
• Plan 2: Read the index where months_of_service=6 (this results in a set of ROWIDs), then access the table based on the ROWIDs returned.

Let's imagine the "employees" table has 1,000,000 (1 million) rows. Let's further imagine that the values for months_of_service range from 1 to 12 and are fairly evenly distributed for some reason.

The cost of Plan 1, which involves a FULL SCAN, will be the cost of reading all the rows in the employees table, which is approximately equal to 1,000,000; but since Oracle will often be able to read the blocks using multi-block reads, the actual cost will be lower (depending on how your database is set up) - e.g. let's imagine the multi-block read count is 10 - the calculated cost of the full scan will be 1,000,000 / 10; Overal cost = 100,000.

The cost of Plan 2, which involves an INDEX RANGE SCAN and a table lookup by ROWID, will be the cost of scanning the index, plus the cost of accessing the table by ROWID. I won't go into how index range scans are costed but let's imagine the cost of the index range scan is 1 per row; we expect to find a match in 1 out of 12 cases, so the cost of the index scan is 1,000,000 / 12 = 83,333; plus the cost of accessing the table (assume 1 block read per access, we can't use multi-block reads here) = 83,333; Overall cost = 166,666.

As you can see, the cost of Plan 1 (full scan) is LESS than the cost of Plan 2 (index scan + access by rowid) - which means the CBO would choose the FULL scan.

If the assumptions made here by the optimiser are true, then in fact Plan 1 will be preferable and much more efficient than Plan 2 - which disproves the myth that FULL scans are "always bad".

The results would be quite different if the optimiser goal was FIRST_ROWS(n) instead of ALL_ROWS - in which case the optimiser would favour Plan 2 because it will often return the first few rows quicker, at the cost of being less efficient for the entire query.

Unfortunately,

mimeType = file.toURL().openConnection().getContentType();

does not work, since this use of URL leaves a file locked, so that, for example, it is undeletable.

However, you have this:

mimeType= URLConnection.guessContentTypeFromName(file.getName());

and also the following, which has the advantage of going beyond mere use of file extension, and takes a peek at content

InputStream is = new BufferedInputStream(new FileInputStream(file));
mimeType = URLConnection.guessContentTypeFromStream(is);
 //...close stream

However, as suggested by the comment above, the built-in table of mime-types is quite limited, not including, for example, MSWord and PDF. So, if you want to generalize, you'll need to go beyond the built-in libraries, using, e.g., Mime-Util (which is a great library, using both file extension and content).

composer.phar can be ran on its own, no need to prefix it with php. This should solve your problem (being in the difference of bash's $PATH and php's include_path).

public List<Student> findStudentByReports(Date startDate, Date endDate) {
    System.out.println("call findStudentMethd******************with this pattern"
                    + startDate
                    + endDate
                    + "*********************************************");

    return em
            .createQuery(
                    "' select attendence from Attendence attendence where attendence.admissionDate BETWEEN : startDate '' AND endDate ''"
                            + "'")
            .setParameter("startDate", startDate, TemporalType.DATE)
            .setParameter("endDate", endDate, TemporalType.DATE)
            .getResultList();

}

In Beautiful Soup, you can pass get_text() the strip parameter, which strips white space from the beginning and end of the text. This will remove \xa0 or any other white space if it occurs at the start or end of the string. Beautiful Soup replaced an empty string with \xa0 and this solved the problem for me.

mytext = soup.get_text(strip=True)

If you want to list Store Procedure for Current Selected Database,

SHOW PROCEDURE STATUS WHERE Db = DATABASE();

it will list Routines based on current selected Database

UPDATED to list out functions in your database

select * from information_schema.ROUTINES where ROUTINE_SCHEMA="YOUR DATABASE NAME" and ROUTINE_TYPE="FUNCTION";

to list out routines/store procedures in your database,

select * from information_schema.ROUTINES where ROUTINE_SCHEMA="YOUR DATABASE NAME" and ROUTINE_TYPE="PROCEDURE";

to list tables in your database,

select * from information_schema.TABLES WHERE TABLE_TYPE="BASE TABLE" AND TABLE_SCHEMA="YOUR DATABASE NAME";

to list views in your database,

method 1:

select * from information_schema.TABLES WHERE TABLE_TYPE="VIEW" AND TABLE_SCHEMA="YOUR DATABASE NAME";

method 2:

select * from information_schema.VIEWS WHERE TABLE_SCHEMA="YOUR DATABASE NAME";

mac os x don't use com numbers. you have to use something like 'ser:devicename' , 9600

From man githooks:

pre-commit
This hook is invoked by git commit, and can be bypassed with --no-verify option. It takes no parameter, and is invoked before obtaining the proposed commit log message and making a commit. Exiting with non-zero status from this script causes the git commit to abort.

SELECT * 
FROM TABLE_NAME
WHERE Date_Column >= DATEADD(MONTH, -3, GETDATE()) 

Mureinik's suggested method will return the same results, but doing it this way your query can benefit from any indexes on Date_Column.

or you can check against last 90 days.

SELECT * 
FROM TABLE_NAME
WHERE Date_Column >= DATEADD(DAY, -90, GETDATE()) 

read with IFS are perfect for this:

$ IFS=- read var1 var2 <<< ABCDE-123456
$ echo "$var1"
ABCDE
$ echo "$var2"
123456

Edit:

Here is how you can read each individual character into array elements:

$ read -a foo <<<"$(echo "ABCDE-123456" | sed 's/./& /g')"

Dump the array:

$ declare -p foo
declare -a foo='([0]="A" [1]="B" [2]="C" [3]="D" [4]="E" [5]="-" [6]="1" [7]="2" [8]="3" [9]="4" [10]="5" [11]="6")'

If there are spaces in the string:

$ IFS=$'\v' read -a foo <<<"$(echo "ABCDE 123456" | sed 's/./&\v/g')"
$ declare -p foo
declare -a foo='([0]="A" [1]="B" [2]="C" [3]="D" [4]="E" [5]=" " [6]="1" [7]="2" [8]="3" [9]="4" [10]="5" [11]="6")'

Basically there are two CER certificate encoding types, DER and Base64. When type DER returns an error loading certificate (asn1 encoding routines), try the PEM and it shall work.

openssl x509 -inform DER -in certificate.cer -out certificate.crt

openssl x509 -inform PEM -in certificate.cer -out certificate.crt

You can use iReport editor to define the layout, and publish the report in jasper reports server. After publish you can invoke the rest api to get the results.

From Oracle 18c you could use DBMS_SESSION.SLEEP procedure:

This procedure suspends the session for a specified period of time.

DBMS_SESSION.SLEEP (seconds  IN NUMBER)

DBMS_SESSION.sleep is available to all sessions with no additional grants needed. Please note that DBMS_LOCK.sleep is deprecated.

If you need simple query sleep you could use WITH FUNCTION:

WITH FUNCTION my_sleep(i NUMBER)
RETURN NUMBER
BEGIN
    DBMS_SESSION.sleep(i);
    RETURN i;
END;
SELECT my_sleep(3) FROM dual;

To hit only cog-icons in that kind of button, you can give the button a class, and set the color for the icon only when inside the button.

HTML:

<a class="my-nice-button" href="/users/edit">
    <i class="icon-cog"></i>
    Edit profile
</a>

CSS:

.my-nice-button>i { color: black; }

This will make any icon that is a direct descendant of your button black.

    cmd.Parameters.AddWithValue("@occ", Mem_Occ);
    con.Open();

    int modified = cmd.ExecuteNonQuery();

    if (con.State == System.Data.ConnectionState.Open) con.Close();
        return modified;

You need to set the password for root@localhost to be blank. There are two ways:

1. The MySQL SET PASSWORD command:

   SET PASSWORD FOR root@localhost=PASSWORD('');
   

2. Using the command-line mysqladmin tool:

   mysqladmin -u root -pType_in_your_current_password_here password ''
   

It's always worth grouping elements into sections that are relevant. In your case, a parent element that contains two columns;

1. icon
2. text.

This fixed the problem for me on Ubuntu:

sudo /var/lib/dpkg/info/ca-certificates-java.postinst configure

(found here: https://bugs.launchpad.net/ubuntu/+source/ca-certificates-java/+bug/1396760)

ca-certificates-java is not a dependency in the Oracle JDK/JRE so this must be explicitly installed.

I'm surprised that no one seems to have pointed out that one can pass a dictionary of keyed argument parameters, that satisfy the formal parameters, like so.

>>> def func(a='a', b='b', c='c', **kwargs):
...    print 'a:%s, b:%s, c:%s' % (a, b, c)
... 
>>> func()
a:a, b:b, c:c
>>> func(**{'a' : 'z', 'b':'q', 'c':'v'})
a:z, b:q, c:v
>>> 

An example is this: You have a string and the character $

String :

aaaaa$bbbbb$ccccc

Code:

SELECT SUBSTRING('aaaaa$bbbbb$ccccc',CHARINDEX('$','aaaaa$bbbbb$ccccc')+1, CHARINDEX('$','aaaaa$bbbbb$ccccc',CHARINDEX('$','aaaaa$bbbbb$ccccc')+1) -CHARINDEX('$','aaaaa$bbbbb$ccccc')-1) as My_String

Output:

bbbbb

Another option is to use JSON.stringify(obj)

For example:

exampleObj = {'a':1,'b':2,'c':3};
alert(JSON.stringify(exampleObj))

https://www.w3schools.com/js/js_json_stringify.asp

try this

   <input type="button" style="background-image:url('your_url')"/>

this is just a shot in the dark : when you call connect without a bind first, the system allocates your local port, and if you have multiple threads connecting and disconnecting it could possibly try to allocate a port already in use. the kernel source file inet_connection_sock.c hints at this condition. just as an experiment try doing a bind to a local port first, making sure each bind/connect uses a different local port number.

For a general solution that works regardless of how many digits are in data$anim, use the sprintf function. It works like this:

sprintf("%04d", 1)
# [1] "0001"
sprintf("%04d", 104)
# [1] "0104"
sprintf("%010d", 104)
# [1] "0000000104"

In your case, you probably want: data$anim <- sprintf("%06d", data$anim)

Windows 10 build 15063 "Creators Update" natively supports SVG images (though with some gotchas) to UWP/UAP applications targeting Windows 10.

If your application is a WPF app rather than a UWP/UAP, you can still use this API (after jumping through quite a number of hoops): Windows 10 build 17763 "October 2018 Update" introduced the concept of XAML islands (as a "preview" technology but I believe allowed in the app store; in all cases, with Windows 10 build 18362 "May 2019 Update" XAML islands are no longer a preview feature and are fully supported) allowing you to use UWP APIs and controls in your WPF applications.

You need to first add the references to the WinRT APIs, and to use certain Windows 10 APIs that interact with user data or the system (e.g. loading images from disk in a Windows 10 UWP webview or using the toast notification API to show toasts), you also need to associate your WPF application with a package identity, as shown here (immensely easier in Visual Studio 2019). This shouldn't be necessary to use the Windows.UI.Xaml.Media.Imaging.SvgImageSource class, though.

Usage (if you're on UWP or you've followed the directions above and added XAML island support under WPF) is as simple as setting the Source for an <Image /> to the path to the SVG. That is equivalent to using SvgImageSource, as follows:

<Image>
    <Image.Source>
        <SvgImageSource UriSource="Assets/svg/icon.svg" />
    </Image.Source>
</Image>

However, SVG images loaded in this way (via XAML) may load jagged/aliased. One workaround is to specify a RasterizePixelHeight or RasterizePixelWidth value that is double+ your actual height/width:

<SvgImageSource RasterizePixelHeight="300" RasterizePixelWidth="300" UriSource="Assets/svg/icon.svg" /> <!-- presuming actual height or width is under 150 -->

This can be worked around dynamically by creating a new SvgImageSource in the ImageOpened event for the base image:

var svgSource = new SvgImageSource(new Uri("ms-appx://" + Icon));
PrayerIcon.ImageOpened += (s, e) =>
{
    var newSource = new SvgImageSource(svgSource.UriSource);
    newSource.RasterizePixelHeight = PrayerIcon.DesiredSize.Height * 2;
    newSource.RasterizePixelWidth = PrayerIcon.DesiredSize.Width * 2;
    PrayerIcon2.Source = newSource;
};
PrayerIcon.Source = svgSource;

The aliasing may be hard to see on non high-dpi screens, but here's an attempt to illustrate it.

This is the result of the code above: an Image that uses the initial SvgImageSource, and a second Image below it that uses the SvgImageSource created in the ImageOpened event:

This is a blown up view of the top image:

Whereas this is a blown-up view of the bottom (antialiased, correct) image:

(you'll need to open the images in a new tab and view at full size to appreciate the difference)

I was having the same issue., OTS parsing error: Failed to convert WOFF 2.0 font to SFNT (index):1 Failed to decode downloaded font: http://dev.xyz/themes/custom/xyz_theme/fonts/xyz_rock/rocksansbold/Rock-SansBold.woff2

If you got this error message while trying to commit your font then it is an issue with .gitattributes "warning: CRLF will be replaced by LF"

The solution for this is adding whichever font you are getting the issue with in .gitattributes

*.ttf     -text diff
*.eot     -text diff
*.woff    -text diff
*.woff2   -text diff

Then I deleted corrupt font files and reapplied the new font files and is working great.

The macros defined in <inttypes.h> are the most correct way to print values of types uint32_t, uint16_t, and so forth -- but they're not the only way.

Personally, I find those macros difficult to remember and awkward to use. (Given the syntax of a printf format string, that's probably unavoidable; I'm not claiming I could have come up with a better system.)

An alternative is to cast the values to a predefined type and use the format for that type.

Types int and unsigned int are guaranteed by the language to be at least 16 bits wide, and therefore to be able to hold any converted value of type int16_t or uint16_t, respectively. Similarly, long and unsigned long are at least 32 bits wide, and long long and unsigned long long are at least 64 bits wide.

For example, I might write your program like this (with a few additional tweaks):

#include <stdio.h>
#include <stdint.h>
#include <netinet/in.h>  

int main(void)
{
    uint32_t a=12, a1;
    uint16_t b=1, b1;
    a1 = htonl(a);
    printf("%lu---------%lu\n", (unsigned long)a, (unsigned long)a1);
    b1 = htons(b);
    printf("%u-----%u\n", (unsigned)b, (unsigned)b1);
    return 0;
}

One advantage of this approach is that it can work even with pre-C99 implementations that don't support <inttypes.h>. Such an implementation most likely wouldn't have <stdint.h> either, but the technique is useful for other integer types.

This is another option:

     switch (true) {
         case (value > 100):
             //do stuff
             break;
         case (value <= 100)&&(value > 75):
             //do stuff
             break;
         case (value < 50):
            //do stuff
             break;
     }

After looking at my .gitmodules, it turned out I did have an uppercase letter where I should not have. So keep in mind, the .gitmodules directories are case sensitive

A double primitive in Java can never be null. It will be initialized to 0.0 if no value has been given for it (except when declaring a local double variable and not assigning a value, but this will produce a compile-time error).

More info on default primitive values here.

You can not remove an item from an IEnumerable; it can only be enumerated, as described here: http://msdn.microsoft.com/en-us/library/system.collections.ienumerable.aspx

You have to use an ICollection if you want to add and remove items. Maybe you can try and casting your IEnumerable; this will off course only work if the underlying object implements ICollection`.

See here for more on ICollection: http://msdn.microsoft.com/en-us/library/92t2ye13.aspx

You can, of course, just create a new list from your IEnumerable, as pointed out by lante, but this might be "sub optimal", depending on your actual use case, of course.

ICollection is probably the way to go.

This also works.

Javascript:

var app = angular.module('angularApp', []);

app.controller('MainCtrl', function($scope, name, id) {
    $scope.id = id;
    $scope.name = name;
    // and more init
});

Html:

<!DOCTYPE html>
<html ng-app="angularApp">
  <head lang="en">
    <script src="//ajax.googleapis.com/ajax/libs/angularjs/1.0.3/angular.min.js"></script>
    <script src="app.js"></script>
    <script>
       app.value("name", "James").value("id", "007");
    </script>
  </head>
  <body ng-controller="MainCtrl">
    <h1>I am  {{name}} {{id}}</h1>
  </body>
</html>

Using the knitr package:

```{r, engine='bash', code_block_name} ...

E.g.:

```{r, engine='bash', count_lines}
wc -l en_US.twitter.txt
```

You can also use:

• engine='sh' for shell
• engine='python' for Python
• engine='perl', engine='haskell' and a bunch of other C-like languages and even gawk, AWK, etc.

You could wrap the hidden div in another div that will toggle the visibility with onMouseOver and onMouseOut event handlers in JavaScript:

<style type="text/css">
  #div1, #div2, #div3 {  
    visibility: hidden;  
  }
</style>
<script>
  function show(id) {
    document.getElementById(id).style.visibility = "visible";
  }
  function hide(id) {
    document.getElementById(id).style.visibility = "hidden";
  }
</script>

<div onMouseOver="show('div1')" onMouseOut="hide('div1')">
  <div id="div1">Div 1 Content</div>
</div>
<div onMouseOver="show('div2')" onMouseOut="hide('div2')">
  <div id="div2">Div 2 Content</div>
</div>
<div onMouseOver="show('div3')" onMouseOut="hide('div3')">
  <div id="div3">Div 3 Content</div>
</div>

You need to install the psycopg2 module.

On CentOS: Make sure Python 2.7+ is installed. If not, follow these instructions: http://toomuchdata.com/2014/02/16/how-to-install-python-on-centos/

# Python 2.7.6:
$ wget http://python.org/ftp/python/2.7.6/Python-2.7.6.tar.xz
$ tar xf Python-2.7.6.tar.xz
$ cd Python-2.7.6
$ ./configure --prefix=/usr/local --enable-unicode=ucs4 --enable-shared LDFLAGS="-Wl,-rpath /usr/local/lib"
$ make && make altinstall
$ yum install postgresql-libs

# First get the setup script for Setuptools:
$ wget https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py

# Then install it for Python 2.7 and/or Python 3.3:
$ python2.7 ez_setup.py

$ easy_install-2.7 psycopg2

Even though this is a CentOS question, here are the instructions for Ubuntu:

$ sudo apt-get install python3-pip python-distribute python-dev
$ easy_install psycopg2

Anyway, I needed a way to catch the inherited Exception and that solution doesn't satisfy all my needs.

So I ended up changing how he handles OnException and this is my version

public override void OnException(HttpActionExecutedContext actionExecutedContext) {
   if (actionExecutedContext == null || actionExecutedContext.Exception == null) {
      return;
   }

   var type = actionExecutedContext.Exception.GetType();

   Tuple<HttpStatusCode?, Func<Exception, HttpRequestMessage, HttpResponseMessage>> registration = null;

   if (!this.Handlers.TryGetValue(type, out registration)) {
      //tento di vedere se ho registrato qualche eccezione che eredita dal tipo di eccezione sollevata (in ordine di registrazione)
      foreach (var item in this.Handlers.Keys) {
         if (type.IsSubclassOf(item)) {
            registration = this.Handlers[item];
            break;
         }
      }
   }

   //se ho trovato un tipo compatibile, uso la sua gestione
   if (registration != null) {
      var statusCode = registration.Item1;
      var handler = registration.Item2;

      var response = handler(
         actionExecutedContext.Exception.GetBaseException(),
         actionExecutedContext.Request
      );

      // Use registered status code if available
      if (statusCode.HasValue) {
         response.StatusCode = statusCode.Value;
      }

      actionExecutedContext.Response = response;
   }
   else {
      // If no exception handler registered for the exception type, fallback to default handler
      actionExecutedContext.Response = DefaultHandler(actionExecutedContext.Exception.GetBaseException(), actionExecutedContext.Request
      );
   }
}

The core is this loop where I check if the exception type is a subclass of a registered type.

foreach (var item in this.Handlers.Keys) {
    if (type.IsSubclassOf(item)) {
        registration = this.Handlers[item];
        break;
    }
}

You can also replace complicated condition with single method call to make it less evil in maintain.

Ohk.. I got it running by typing /usr/bin/phpize instead of only phpize.

Instead of converting the class to a function, an easy step would be to create a function to include the jsx for the component which uses the 'classes', in your case the <container></container> and then call this function inside the return of the class render() as a tag. This way you are moving out the hook to a function from the class. It worked perfectly for me. In my case it was a <table> which i moved to a function- TableStmt outside and called this function inside the render as <TableStmt/>

A jQuery solution would be something like:

$(function () {
    $('input').blur();
});

According to @senderle, if you use python3.6 like me:

def sh(cmd, input=""):
    rst = subprocess.run(cmd, shell=True, stdout=subprocess.PIPE, stderr=subprocess.PIPE, input=input.encode("utf-8"))
    assert rst.returncode == 0, rst.stderr.decode("utf-8")
    return rst.stdout.decode("utf-8")

sh("ls -a")

Will act exactly like you run the command in bash

The question is already answered... but I wanted to show how to add shadow and change the font with NSAttributedString as well, so that when people search for this topic they won't have to keep looking.

#define FONT_SIZE 20
#define FONT_HELVETICA @"Helvetica-Light"
#define BLACK_SHADOW [UIColor colorWithRed:40.0f/255.0f green:40.0f/255.0f blue:40.0f/255.0f alpha:0.4f]

NSString*myNSString = @"This is my string.\nIt goes to a second line.";                

NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle alloc] init];
               paragraphStyle.alignment = NSTextAlignmentCenter;
             paragraphStyle.lineSpacing = FONT_SIZE/2;
                     UIFont * labelFont = [UIFont fontWithName:FONT_HELVETICA size:FONT_SIZE];
                   UIColor * labelColor = [UIColor colorWithWhite:1 alpha:1];
                       NSShadow *shadow = [[NSShadow alloc] init];
                 [shadow setShadowColor : BLACK_SHADOW];
                [shadow setShadowOffset : CGSizeMake (1.0, 1.0)];
            [shadow setShadowBlurRadius : 1];

NSAttributedString *labelText = [[NSAttributedString alloc] initWithString : myNSString
                      attributes : @{
   NSParagraphStyleAttributeName : paragraphStyle,
             NSKernAttributeName : @2.0,
             NSFontAttributeName : labelFont,
  NSForegroundColorAttributeName : labelColor,
           NSShadowAttributeName : shadow }];

Here is a Swift version...

Warning! This works for 4s.

For 5s you have to change all of the the Float values to Double values (because the compiler isn't working correctly yet)

Swift enum for font choice:

enum FontValue: Int {
    case FVBold = 1 , FVCondensedBlack, FVMedium, FVHelveticaNeue, FVLight, FVCondensedBold, FVLightItalic, FVUltraLightItalic, FVUltraLight, FVBoldItalic, FVItalic
}

Swift array for enum access (needed because enum can't use '-'):

func helveticaFont (index:Int) -> (String) {
    let fontArray = [
    "HelveticaNeue-Bold",
    "HelveticaNeue-CondensedBlack",
    "HelveticaNeue-Medium",
    "HelveticaNeue",
    "HelveticaNeue-Light",
    "HelveticaNeue-CondensedBold",
    "HelveticaNeue-LightItalic",
    "HelveticaNeue-UltraLightItalic",
    "HelveticaNeue-UltraLight",
    "HelveticaNeue-BoldItalic",
    "HelveticaNeue-Italic",
    ]
    return fontArray[index]
}

Swift attributed text function:

func myAttributedText (myString:String, mySize: Float, myFont:FontValue) -> (NSMutableAttributedString) {

    let shadow = NSShadow()
    shadow.shadowColor = UIColor.textShadowColor()
    shadow.shadowOffset = CGSizeMake (1.0, 1.0)
    shadow.shadowBlurRadius = 1

    let paragraphStyle = NSMutableParagraphStyle.alloc()
    paragraphStyle.lineHeightMultiple = 1
    paragraphStyle.lineBreakMode = NSLineBreakMode.ByWordWrapping
    paragraphStyle.alignment = NSTextAlignment.Center

    let labelFont = UIFont(name: helveticaFont(myFont.toRaw()), size: mySize)
    let labelColor = UIColor.whiteColor()

    let myAttributes :Dictionary = [NSParagraphStyleAttributeName : paragraphStyle,
                                              NSKernAttributeName : 3, // (-1,5)
                                              NSFontAttributeName : labelFont,
                                   NSForegroundColorAttributeName : labelColor,
                                            NSShadowAttributeName : shadow]

    let myAttributedString = NSMutableAttributedString (string: myString, attributes:myAttributes)

    // add new color 
    let secondColor = UIColor.blackColor()
    let stringArray = myString.componentsSeparatedByString(" ")
    let firstString: String? = stringArray.first
    let letterCount = countElements(firstString!)
    if firstString {
        myAttributedString.addAttributes([NSForegroundColorAttributeName:secondColor], range:NSMakeRange(0,letterCount))
    }

    return  myAttributedString
}

first and last extension used for finding ranges in a string array:

            return self [0]
        } else {
            return self[self.endIndex - 1]
        }
    }
}

extension Array {
    var first: T? {
        if self.isEmpty {
            NSLog("array crash error - please fix")
            return self [0]
        } else {
            return self [0]
        }
    }
}

new colors:

    class func shadowColor() -> UIColor {
        return UIColor(red: 0.0/255.0, green: 0.0/255.0, blue: 0.0/255.0, alpha: 0.3)
    }
    class func textShadowColor() -> UIColor {

my macro replacement:

enum MyConstants: Float {
    case CornerRadius = 5.0
}

my button maker w/attributed text:

generic shadow add:

func viewshadow<T where T: UIView> (shadowObject: T)
{
    let layer = shadowObject.layer
    let radius = shadowObject.frame.size.width / MyConstants.CornerRadius.toRaw();
    layer.borderColor = UIColor.whiteColor().CGColor

    layer.shadowOpacity = 1
    layer.shadowRadius = 3
    layer.shadowOffset = CGSizeMake(2.0,2.0)

        let frame = self.frame
        let myColor = self.backgroundColor
        layer.borderColor = myColor.CGColor

        self.layer.insertSublayer(layer, atIndex: 2)
    }
}

the actual view did load function:

func buttonPress (sender:UIButton!) {
    NSLog("%@", "ButtonPressed")
}

override func viewDidLoad() {
    super.viewDidLoad()

    let myLabel = myLabelMaker(myView)
    let myButton = myButtonMaker(myView)

    myButton.addTarget(self, action: "buttonPress:", forControlEvents:UIControlEvents.TouchUpInside)

    viewshadow(myButton)
    viewshadow(myLabel)

}

Once after we build the jar will have the resource files under BOOT-INF/classes or target/classes folder, which is in classpath, use the below method and pass the file under the src/main/resources as method call getAbsolutePath("certs/uat_staging_private.ppk"), even we can place this method in Utility class and the calling Thread instance will be taken to load the ClassLoader to get the resource from class path.

 public String getAbsolutePath(String fileName) throws IOException {
      return Thread.currentThread().getContextClassLoader().getResource(fileName).getFile();
  }

we can add the below tag to tag in pom.xml to include these resource files to build target/classes folder

<resources>
        <resource>
            <directory>src/main/resources</directory>
            <includes>
                <include>**/*.properties</include>
                <include>**/*.ppk</include>
            </includes>
        </resource>
</resources>

There isn't really a "private method" in Objective-C, if the runtime can work out which implementation to use it will do it. But that's not to say that there aren't methods which aren't part of the documented interface. For those methods I think that a category is fine. Rather than putting the @interface at the top of the .m file like your point 2, I'd put it into its own .h file. A convention I follow (and have seen elsewhere, I think it's an Apple convention as Xcode now gives automatic support for it) is to name such a file after its class and category with a + separating them, so @interface GLObject (PrivateMethods) can be found in GLObject+PrivateMethods.h. The reason for providing the header file is so that you can import it in your unit test classes :-).

By the way, as far as implementing/defining methods near the end of the .m file is concerned, you can do that with a category by implementing the category at the bottom of the .m file:

@implementation GLObject(PrivateMethods)
- (void)secretFeature;
@end

or with a class extension (the thing you call an "empty category"), just define those methods last. Objective-C methods can be defined and used in any order in the implementation, so there's nothing to stop you putting the "private" methods at the end of the file.

Even with class extensions I will often create a separate header (GLObject+Extension.h) so that I can use those methods if required, mimicking "friend" or "protected" visibility.

Since this answer was originally written, the clang compiler has started doing two passes for Objective-C methods. This means you can avoid declaring your "private" methods completely, and whether they're above or below the calling site they'll be found by the compiler.

In my case I tried everything that was listed above. I was using Laravel and Vagrant with 4GB of memory and a swap, with memory limit set to -1. I deleted the vendor/ and tried other PHP-versions. Finally, I managed it to work by running

vagrant halt
vagrant up

And then composer install worked again as usual.

Possible solutions -
1.Make sure that you don't have any other element with name/id as submit.
2.Try to call the function as onClick = "return submitAction();"
3.document.getElementById("form-name").submit();

Instead of doing:

git fetch --all
git reset --hard origin/master

I'd advise doing the following:

git fetch origin master
git reset --hard origin/master

No need to fetch all remotes and branches if you're going to reset to the origin/master branch right?

[A1].End(xlUp)
[A1].End(xlDown)
[A1].End(xlToLeft)
[A1].End(xlToRight)

is the VBA equivalent of being in Cell A1 and pressing Ctrl + Any arrow key. It will continue to travel in that direction until it hits the last cell of data, or if you use this command to move from a cell that is the last cell of data it will travel until it hits the next cell containing data.

If you wanted to find that last "used" cell in Column A, you could go to A65536 (for example, in an XL93-97 workbook) and press Ctrl + Up to "snap" to the last used cell. Or in VBA you would write:

Range("A65536").End(xlUp) which again can be re-written as Range("A" & Rows.Count).End(xlUp) for compatibility reasons across workbooks with different numbers of rows.

If you want to upload multiple images at once you can add multiple attribute to input.

upload multiple files: <input type="file" multiple accept='image/*'>

I had this issue when I forgot to add the new .h/.c file I created to the meson recipe so this is just a friendly reminder.

I had the same problem and later I realised that my app-routing.module.ts was inside a sub folder called app-routing. I moved this file directly under src and now it is working. (Now app-routing file has access to all the components)

To make it simple,

1. Container ID is your host name inside docker
2. Container information is available inside /proc/self/cgroup

To get host name,

hostname

or

uname -n

or

cat /etc/host

Output can be redirected to any file & read back from application E.g.: # hostname > /usr/src//hostname.txt

input_str = "ABC"
[bin(byte) for byte in bytes(input_str, "utf-8")]

Will give:

['0b1000001', '0b1000010', '0b1000011']

This worked for me perfectly fine.

    select name, orderno from (
         select name, orderno, row_number() over(partition by 
           orderno order by created_date desc) as rn from orders
    ) O where rn =1;

Based on generality of this question, I think, that you'll need to setup your own HTTPS proxy on some server online. Do the following steps:

• Prepare your proxy server - install IIS, Apache
• Get valid SSL certificate to avoid security errors (free from startssl.com for example)
• Write a wrapper, which will download insecure content (how to below)
• From your site/app get https://yourproxy.com/?page=http://insecurepage.com

If you simply download remote site content via file_get_contents or similiar, you can still have insecure links to content. You'll have to find them with regex and also replace. Images are hard to solve, but Ï found workaround here: http://foundationphp.com/tutorials/image_proxy.php

Note: While this solution may have worked in some browsers when it was written in 2014, it no longer works. Navigating or redirecting to an HTTP URL in an iframe embedded in an HTTPS page is not permitted by modern browsers, even if the frame started out with an HTTPS URL.

The best solution I created is to simply use google as the ssl proxy...

https://www.google.com/search?q=%http://yourhttpsite.com&btnI=Im+Feeling+Lucky

Tested and works in firefox.

Other Methods:

• Use a Third party such as embed.ly (but it it really only good for well known http APIs).

• Create your own redirect script on an https page you control (a simple javascript redirect on a relative linked page should do the trick. Something like: (you can use any langauge/method)

  https://example.com That has a iframe linking to...

  https://example.com/utilities/redirect.html Which has a simple js redirect script like...

  document.location.href ="http://thenonsslsite.com";

• Alternatively, you could add an RSS feed or write some reader/parser to read the http site and display it within your https site.

• You could/should also recommend to the http site owner that they create an ssl connection. If for no other reason than it increases seo.

Unless you can get the http site owner to create an ssl certificate, the most secure and permanent solution would be to create an RSS feed grabing the content you need (presumably you are not actually 'doing' anything on the http site -that is to say not logging in to any system).

The real issue is that having http elements inside a https site represents a security issue. There are no completely kosher ways around this security risk so the above are just current work arounds.

Note, that you can disable this security measure in most browsers (yourself, not for others). Also note that these 'hacks' may become obsolete over time.

I advocate an object oriented approach. This is the template that I start out with:

# Use Tkinter for python 2, tkinter for python 3
import tkinter as tk

class MainApplication(tk.Frame):
    def __init__(self, parent, *args, **kwargs):
        tk.Frame.__init__(self, parent, *args, **kwargs)
        self.parent = parent

        <create the rest of your GUI here>

if __name__ == "__main__":
    root = tk.Tk()
    MainApplication(root).pack(side="top", fill="both", expand=True)
    root.mainloop()

The important things to notice are:

• I don't use a wildcard import. I import the package as "tk", which requires that I prefix all commands with tk.. This prevents global namespace pollution, plus it makes the code completely obvious when you are using Tkinter classes, ttk classes, or some of your own.

• The main application is a class. This gives you a private namespace for all of your callbacks and private functions, and just generally makes it easier to organize your code. In a procedural style you have to code top-down, defining functions before using them, etc. With this method you don't since you don't actually create the main window until the very last step. I prefer inheriting from tk.Frame just because I typically start by creating a frame, but it is by no means necessary.

If your app has additional toplevel windows, I recommend making each of those a separate class, inheriting from tk.Toplevel. This gives you all of the same advantages mentioned above -- the windows are atomic, they have their own namespace, and the code is well organized. Plus, it makes it easy to put each into its own module once the code starts to get large.

Finally, you might want to consider using classes for every major portion of your interface. For example, if you're creating an app with a toolbar, a navigation pane, a statusbar, and a main area, you could make each one of those classes. This makes your main code quite small and easy to understand:

class Navbar(tk.Frame): ...
class Toolbar(tk.Frame): ...
class Statusbar(tk.Frame): ...
class Main(tk.Frame): ...

class MainApplication(tk.Frame):
    def __init__(self, parent, *args, **kwargs):
        tk.Frame.__init__(self, parent, *args, **kwargs)
        self.statusbar = Statusbar(self, ...)
        self.toolbar = Toolbar(self, ...)
        self.navbar = Navbar(self, ...)
        self.main = Main(self, ...)

        self.statusbar.pack(side="bottom", fill="x")
        self.toolbar.pack(side="top", fill="x")
        self.navbar.pack(side="left", fill="y")
        self.main.pack(side="right", fill="both", expand=True)

Since all of those instances share a common parent, the parent effectively becomes the "controller" part of a model-view-controller architecture. So, for example, the main window could place something on the statusbar by calling self.parent.statusbar.set("Hello, world"). This allows you to define a simple interface between the components, helping to keep coupling to a minimun.

A base

function Base(kind) {
    this.kind = kind;
}

A class

// Shared var
var _greeting;

(function _init() {
    Class.prototype = new Base();
    Class.prototype.constructor = Class;
    Class.prototype.log = function() { _log.apply(this, arguments); }
    _greeting = "Good afternoon!";
})();

function Class(name, kind) {
    Base.call(this, kind);
    this.name = name;
}

// Shared function
function _log() {
    console.log(_greeting + " Me name is " + this.name + " and I'm a " + this.kind);
}

Action

var c = new Class("Joe", "Object");
c.log(); // "Good afternoon! Me name is Joe and I'm a Object"

HTML5 does not directly support requiring only one/at least one checkbox be checked in a checkbox group. Here is my solution using Javascript:

HTML

<input class='acb' type='checkbox' name='acheckbox[]' value='1' onclick='deRequire("acb")' required> One
<input class='acb' type='checkbox' name='acheckbox[]' value='2' onclick='deRequire("acb")' required> Two

JAVASCRIPT

       function deRequireCb(elClass) {
            el=document.getElementsByClassName(elClass);

            var atLeastOneChecked=false;//at least one cb is checked
            for (i=0; i<el.length; i++) {
                if (el[i].checked === true) {
                    atLeastOneChecked=true;
                }
            }

            if (atLeastOneChecked === true) {
                for (i=0; i<el.length; i++) {
                    el[i].required = false;
                }
            } else {
                for (i=0; i<el.length; i++) {
                    el[i].required = true;
                }
            }
        }

The javascript will ensure at least one checkbox is checked, then de-require the entire checkbox group. If the one checkbox that is checked becomes un-checked, then it will require all checkboxes, again!

Looking at this official google link: Youtube Live encoder settings, bitrates and resolutions they have this table:

                   240p       360p        480p        720p        1080p
Resolution      426 x 240   640 x 360   854x480     1280x720    1920x1080
Video Bitrates                   
Maximum         700 Kbps    1000 Kbps   2000 Kbps   4000 Kbps   6000 Kbps
Recommended     400 Kbps    750 Kbps    1000 Kbps   2500 Kbps   4500 Kbps
Minimum         300 Kbps    400 Kbps    500 Kbps    1500 Kbps   3000 Kbps

It would appear as though this is the case, although the numbers dont sync up to the google table above:

// the bitrates, video width and file names for this clip
      bitrates: [
        { url: "bbb-800.mp4", width: 480, bitrate: 800 }, //360p video
        { url: "bbb-1200.mp4", width: 720, bitrate: 1200 }, //480p video
        { url: "bbb-1600.mp4", width: 1080, bitrate: 1600 } //720p video
      ],

I had similar situation. Here is what I did:

Try to check and uncheck the USB Debugging option in the device. (if not working, try to unplug/plug the USB)

At some point, the device should show up a messagebox to ask you if you authorize the computer. After you click yes, the device is then authorized and the connection is hooked.

I think there is a lot of confusion about which weights are used for what. I am not sure I know precisely what bothers you so I am going to cover different topics, bear with me ;).

Class weights

The weights from the class_weight parameter are used to train the classifier. They are not used in the calculation of any of the metrics you are using: with different class weights, the numbers will be different simply because the classifier is different.

Basically in every scikit-learn classifier, the class weights are used to tell your model how important a class is. That means that during the training, the classifier will make extra efforts to classify properly the classes with high weights.
How they do that is algorithm-specific. If you want details about how it works for SVC and the doc does not make sense to you, feel free to mention it.

The metrics

Once you have a classifier, you want to know how well it is performing. Here you can use the metrics you mentioned: accuracy, recall_score, f1_score...

Usually when the class distribution is unbalanced, accuracy is considered a poor choice as it gives high scores to models which just predict the most frequent class.

I will not detail all these metrics but note that, with the exception of accuracy, they are naturally applied at the class level: as you can see in this print of a classification report they are defined for each class. They rely on concepts such as true positives or false negative that require defining which class is the positive one.

             precision    recall  f1-score   support

          0       0.65      1.00      0.79        17
          1       0.57      0.75      0.65        16
          2       0.33      0.06      0.10        17
avg / total       0.52      0.60      0.51        50

The warning

F1 score:/usr/local/lib/python2.7/site-packages/sklearn/metrics/classification.py:676: DeprecationWarning: The 
default `weighted` averaging is deprecated, and from version 0.18, 
use of precision, recall or F-score with multiclass or multilabel data  
or pos_label=None will result in an exception. Please set an explicit 
value for `average`, one of (None, 'micro', 'macro', 'weighted', 
'samples'). In cross validation use, for instance, 
scoring="f1_weighted" instead of scoring="f1".

You get this warning because you are using the f1-score, recall and precision without defining how they should be computed! The question could be rephrased: from the above classification report, how do you output one global number for the f1-score? You could:

1. Take the average of the f1-score for each class: that's the avg / total result above. It's also called macro averaging.
2. Compute the f1-score using the global count of true positives / false negatives, etc. (you sum the number of true positives / false negatives for each class). Aka micro averaging.
3. Compute a weighted average of the f1-score. Using 'weighted' in scikit-learn will weigh the f1-score by the support of the class: the more elements a class has, the more important the f1-score for this class in the computation.

These are 3 of the options in scikit-learn, the warning is there to say you have to pick one. So you have to specify an average argument for the score method.

Which one you choose is up to how you want to measure the performance of the classifier: for instance macro-averaging does not take class imbalance into account and the f1-score of class 1 will be just as important as the f1-score of class 5. If you use weighted averaging however you'll get more importance for the class 5.

The whole argument specification in these metrics is not super-clear in scikit-learn right now, it will get better in version 0.18 according to the docs. They are removing some non-obvious standard behavior and they are issuing warnings so that developers notice it.

Computing scores

Last thing I want to mention (feel free to skip it if you're aware of it) is that scores are only meaningful if they are computed on data that the classifier has never seen. This is extremely important as any score you get on data that was used in fitting the classifier is completely irrelevant.

Here's a way to do it using StratifiedShuffleSplit, which gives you a random splits of your data (after shuffling) that preserve the label distribution.

from sklearn.datasets import make_classification
from sklearn.cross_validation import StratifiedShuffleSplit

Use assertNotNull(obj). assert means must be.

Depending on your platform you can use: sqlite3 file_name.db from the terminal. .tables will list the tables, .schema is full layout. SQLite commands like: select * from table_name; and such will print out the full contents. Type: ".exit" to exit. No need to download a GUI application.Use a semi-colon if you want it to execute a single command. Decent SQLite usage tutorial http://www.thegeekstuff.com/2012/09/sqlite-command-examples/

SELECT * FROM tablename WHERE STR_TO_DATE(columnname, '%d/%m/%Y')
  BETWEEN STR_TO_DATE('29/05/2017', '%d/%m/%Y')
    AND STR_TO_DATE('30/05/2017', '%d/%m/%Y')

It works perfectly :)

Here's a bit of script I use for testing if a server is 2005 or later

declare @isSqlServer2005 bit
select @isSqlServer2005 = case when CONVERT(int, SUBSTRING(CONVERT(varchar(15), SERVERPROPERTY('productversion')), 0, CHARINDEX('.', CONVERT(varchar(15), SERVERPROPERTY('productversion'))))) < 9 then 0 else 1 end
select @isSqlServer2005

This probably won't help too many people, but this was my case: I was using the Jira Rest Api and was using my personal credentials (the ones I use to log into Jira). I had updated my Jira password but forgot to update them in my code. I got the 403 error, I tried updating my password in the code but still got the error.

The solution: I tried logging into Jira (from their login page) and I had to enter the text to prove I wasn't a bot. After that I tried again from the code and it worked. Takeaway: The server may have locked you out.

I'm using an MVC / MVA design pattern, with multiple types of "views". One type is a "GuiView", which is a Tk window. I pass a view reference to my window object which does things like link buttons back to view functions (which the adapter / controller class also calls).

In order to do that, the view object constructor needed to be completed prior to creating the window object. After creating and displaying the window, I wanted to do some initial tasks with the view automatically. At first I tried doing them post mainloop(), but that didn't work because mainloop() blocked!

As such, I created the window object and used tk.update() to draw it. Then, I kicked off my initial tasks, and finally started the mainloop.

import Tkinter as tk

class Window(tk.Frame):
    def __init__(self, master=None, view=None ):
        tk.Frame.__init__( self, master )
        self.view_ = view       
        """ Setup window linking it to the view... """

class GuiView( MyViewSuperClass ):

    def open( self ):
        self.tkRoot_ = tk.Tk()
        self.window_ = Window( master=None, view=self )
        self.window_.pack()
        self.refresh()
        self.onOpen()
        self.tkRoot_.mainloop()         

    def onOpen( self ):        
        """ Do some initial tasks... """

    def refresh( self ):        
        self.tkRoot_.update()

for(map<string, pair<string,string> >::const_iterator it = myMap.begin();
    it != myMap.end(); ++it)
{
    std::cout << it->first << " " << it->second.first << " " << it->second.second << "\n";
}

In C++11, you don't need to spell out map<string, pair<string,string> >::const_iterator. You can use auto

for(auto it = myMap.cbegin(); it != myMap.cend(); ++it)
{
    std::cout << it->first << " " << it->second.first << " " << it->second.second << "\n";
}

Note the use of cbegin() and cend() functions.

Easier still, you can use the range-based for loop:

for(auto elem : myMap)
{
   std::cout << elem.first << " " << elem.second.first << " " << elem.second.second << "\n";
}

One simple possibility would be to make an array of 26 ints, each is a count for a letter a-z:

int alphacount[26] = {0}; //[0] = 'a', [1] = 'b', etc

Then loop through the string and increment the count for each letter:

for(int i = 0; i<strlen(mystring); i++)      //for the whole length of the string
    if(isalpha(mystring[i]))
        alphacount[tolower(mystring[i])-'a']++;  //make the letter lower case (if it's not)
                                                 //then use it as an offset into the array
                                                 //and increment

It's a simple idea that works for A-Z, a-z. If you want to separate by capitals you just need to make the count 52 instead and subtract the correct ASCII offset

In your example you do not know the number of iterations for the for loop. Why not use while loop instead, which allows the number of iterations to be indeterminate at the beginning?

It is hence not necessary to use break statemement in general, as the loop can be better stated as a while loop.

For me below code worked, first sending json string with proper headers

$.ajax({
        type: "POST",
        url : 'save',
        data : JSON.stringify(valObject),
        contentType:"application/json; charset=utf-8",
        dataType:"json",
        success : function(resp){
            console.log(resp);
        },
        error : function(resp){
            console.log(resp);
        }
    });

And then on Spring side -

@RequestMapping(value = "/save", 
                method = RequestMethod.POST,
                consumes="application/json")
public @ResponseBody String  save(@RequestBody ArrayList<KeyValue> keyValList) {
    //Saving call goes here
    return "";
}

Here KeyValue is simple pojo that corresponds to your JSON structure also you can add produces as you wish, I am simply returning string.

My json object is like this -

[{"storedKey":"vc","storedValue":"1","clientId":"1","locationId":"1"},
 {"storedKey":"vr","storedValue":"","clientId":"1","locationId":"1"}]

The DBHelper class is what handles the opening and closing of sqlite databases as well sa creation and updating, and a decent article on how it all works is here. When I started android it was very useful (however I've been objective-c lately, and forgotten most of it to be any use.

Jeff Atwood had a few things to say about this issue in Determining Build Date the hard way.

The most reliable method turns out to be retrieving the linker timestamp from the PE header embedded in the executable file -- some C# code (by Joe Spivey) for that from the comments to Jeff's article:

public static DateTime GetLinkerTime(this Assembly assembly, TimeZoneInfo target = null)
{
    var filePath = assembly.Location;
    const int c_PeHeaderOffset = 60;
    const int c_LinkerTimestampOffset = 8;

    var buffer = new byte[2048];

    using (var stream = new FileStream(filePath, FileMode.Open, FileAccess.Read))
        stream.Read(buffer, 0, 2048);

    var offset = BitConverter.ToInt32(buffer, c_PeHeaderOffset);
    var secondsSince1970 = BitConverter.ToInt32(buffer, offset + c_LinkerTimestampOffset);
    var epoch = new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc);

    var linkTimeUtc = epoch.AddSeconds(secondsSince1970);

    var tz = target ?? TimeZoneInfo.Local;
    var localTime = TimeZoneInfo.ConvertTimeFromUtc(linkTimeUtc, tz);

    return localTime;
}

Usage example:

var linkTimeLocal = Assembly.GetExecutingAssembly().GetLinkerTime();

UPDATE: The method was working for .Net Core 1.0, but stopped working after .Net Core 1.1 release(gives random years in 1900-2020 range)

In addition to other answers, I would like to add one image for it(pic makes easy to understand)

static variables may be cached for individual threads. In multi-threaded environment if one thread modifies its cached data, that may not reflect for other threads as they have a copy of it.

volatile declaration makes sure that threads won't cache the data and uses the shared copy only.

image source

var _RemoveBtn = document.getElementsByClassName("remove");
for(var i=0 ;  i<_RemoveBtn.length ; i++){
    _RemoveBtn[i].addEventListener('click',sample,false);
}
function sample(event){
    console.log(event.currentTarget.parentNode);    
}

The main difference is that a 8-bit PNG comprises a max. of 256 colours, like GIFs. PNG-24 is a lossless format and can contain up to 16 million colours.

It seems like what you want is http://msdn.microsoft.com/en-us/library/ms186323.aspx.

In your example it would be (starts with):

set @isExpress = (CharIndex('Express Edition', @edition) = 1)

Or contains

set @isExpress = (CharIndex('Express Edition', @edition) >= 1)

I use a slight evolution of @hugo_leonardo 's solution:

<?php

return (object) array(
    'host' => 'localhost',
    'username' => 'root',
    'pass' => 'password',
    'database' => 'db'
);

?>

This allows you to use the object syntax when you include the php : $configs->host instead of $configs['host'].

Also, if your app has configs you need on the client side (like for an Angular app), you can have this config.php file contain all your configs (centralized in one file instead of one for JavaScript and one for PHP). The trick would then be to have another PHP file that would echo only the client side info (to avoid showing info you don't want to show like database connection string). Call it say get_app_info.php :

<?php

    $configs = include('config.php');
    echo json_encode($configs->app_info);

?>

The above assuming your config.php contains an app_info parameter:

<?php

return (object) array(
    'host' => 'localhost',
    'username' => 'root',
    'pass' => 'password',
    'database' => 'db',
    'app_info' => array(
        'appName'=>"App Name",
        'appURL'=> "http://yourURL/#/"
    )
);

?>

So your database's info stays on the server side, but your app info is accessible from your JavaScript, with for example a $http.get('get_app_info.php').then(...); type of call.

I can't tell you which of these methods will be best on H2 (or even if all of them will work), but I did write an article detailing all of the (good) methods available in TSQL. You can give them a shot and see if any of them works for you:

http://code.msdn.microsoft.com/SQLExamples/Wiki/View.aspx?title=QueryBasedUponAbsenceOfData&referringTitle=Home

All of these answers should suffice. However if you don't have a defined width, auto margins will not work.

I have found this nifty little trick to centre some of the more stubborn elements (Particularly images).

.div {
   position: absolute;
   left: 0;
   right: 0;
   margin-left: 0;
   margin-right: 0;
}

The apps UI only works for panels.

The best you can do is to draw a button yourself and put that into your spreadsheet. Than you can add a macro to it.

Go into "Insert > Drawing...", Draw a button and add it to the spreadsheet. Than click it and click "assign Macro...", then insert the name of the function you wish to execute there. The function must be defined in a script in the spreadsheet.

Alternatively you can also draw the button somewhere else and insert it as an image.

Using seeds.rb file or FactoryBot is great, but these are respectively great for fixed data structures and testing.

The seedbank gem might give you more control and modularity to your seeds. It inserts rake tasks and you can also define dependencies between your seeds. Your rake task list will have these additions (e.g.):

rake db:seed                    # Load the seed data from db/seeds.rb, db/seeds/*.seeds.rb and db/seeds/ENVIRONMENT/*.seeds.rb. ENVIRONMENT is the current environment in Rails.env.
rake db:seed:bar                # Load the seed data from db/seeds/bar.seeds.rb
rake db:seed:common             # Load the seed data from db/seeds.rb and db/seeds/*.seeds.rb.
rake db:seed:development        # Load the seed data from db/seeds.rb, db/seeds/*.seeds.rb and db/seeds/development/*.seeds.rb.
rake db:seed:development:users  # Load the seed data from db/seeds/development/users.seeds.rb
rake db:seed:foo                # Load the seed data from db/seeds/foo.seeds.rb
rake db:seed:original           # Load the seed data from db/seeds.rb

This is because you are reading a cursor, not an array. This means that you are reading sequentially through the results and when you get to the end you would need to reset the cursor to the beginning of the results to read them again.

If you did want to read over the results multiple times, you could use fetchAll to read the results into a true array and then it would work as you are expecting.

A small but important detail for adjusting figure size on a one-off basis (as several commenters above reported "this doesn't work for me"):

You should do plt.figure(figsize=(,)) PRIOR to defining your actual plot. For example:

This should correctly size the plot according to your specified figsize:

values = [1,1,1,2,2,3]
_ = plt.figure(figsize=(10,6))
_ = plt.hist(values,bins=3)
plt.show()

Whereas this will show the plot with the default settings, seeming to "ignore" figsize:

values = [1,1,1,2,2,3]
_ = plt.hist(values,bins=3)
_ = plt.figure(figsize=(10,6))
plt.show()

1. Click "Source Control" button on left.

Some of these above answers didn't work for me but this did. Just in case someone else has the same issue.

ng-show="column != 'vendorid' && column !='billingMonth'"

There are a couple of things that need to be adjusted in your layout:

1. You are nesting col elements within form-group elements. This should be the other way around (the form-group should be within the col-sm-xx element).

2. You should always use a row div for each new "row" in your design. In your case, you would need at least 5 rows (Username, Password and co, Title/First/Last name, email, Language). Otherwise, your problematic .col-sm-12 is still on the same row with the above 3 .col-sm-4 resulting in a total of columns greater than 12, and causing the overlap problem.

Here is a fixed demo.

And an excerpt of what the problematic section HTML should become:

<fieldset>
    <legend>Personal Information</legend>
    <div class='row'>
        <div class='col-sm-4'>    
            <div class='form-group'>
                <label for="user_title">Title</label>
                <input class="form-control" id="user_title" name="user[title]" size="30" type="text" />
            </div>
        </div>
        <div class='col-sm-4'>
            <div class='form-group'>
                <label for="user_firstname">First name</label>
                <input class="form-control" id="user_firstname" name="user[firstname]" required="true" size="30" type="text" />
            </div>
        </div>
        <div class='col-sm-4'>
            <div class='form-group'>
                <label for="user_lastname">Last name</label>
                <input class="form-control" id="user_lastname" name="user[lastname]" required="true" size="30" type="text" />
            </div>
        </div>
    </div>
    <div class='row'>
        <div class='col-sm-12'>
            <div class='form-group'>

                <label for="user_email">Email</label>
                <input class="form-control required email" id="user_email" name="user[email]" required="true" size="30" type="text" />
            </div>
        </div>
    </div>
</fieldset>

KEY and INDEX are synonyms.

You should add an index when performance measurements and EXPLAIN shows you that the query is inefficient because of a missing index. Adding an index can improve the performance of queries (but it can slow down modifications to the table).

You should use UNIQUE when you want to contrain the values in that column (or columns) to be unique, so that attempts to insert duplicate values result in an error.

A PRIMARY KEY is both a unique constraint and it also implies that the column is NOT NULL. It is used to give an identity to each row. This can be useful for joining with another table via a foreign key constraint. While it is not required for a table to have a PRIMARY KEY it is usually a good idea.

List<Map<String, Object>> List = getJdbcTemplate().queryForList(SELECT_ALL_CONVERSATIONS_SQL_FULL, new Object[] {userId, dateFrom, dateTo});
for (Map<String, Object> rowMap : resultList) {
    DTO dTO = new DTO();
    dTO.setrarchyID((Long) (rowMap.get("ID")));
}

If you want to go even further than @tetra with ES6 you can use the Object spread syntax and do something like this:

let john = {
    firstName: "John",
    lastName: "Doe",
};

let people = new Array(10).fill().map((e, i) => {(...john, id: i});

A notable 'gotcha' dictates that you should never include more than one input element inside of a <label> element with an explicit "for" attribute, e.g:

<label for="child-input-1">
  <input type="radio" id="child-input-1"/>
  <span> Associate the following text with the selected radio button: </span>
  <input type="text" id="child-input-2"/>
</label>

While this may be tempting for form features in which a custom text value is secondary to a radio button or checkbox, the click-focus functionality of the label element will immediately throw focus to the element whose id is explicitly defined in its 'for' attribute, making it nearly impossible for the user to click into the contained text field to enter a value.

Personally, I try to avoid label elements with input children. It seems semantically improper for a label element to encompass more than the label itself. If you're nesting inputs in labels in order to achieve a certain aesthetic, you should be using CSS instead.

You should really check the log. It seems that quite a few components can cause the Windows SDK installer to fail to install with this useless error message. For instance it could be the Visual C++ Redistributable Package as mentioned there.

You can use the ExceptionUtils.getStackTrace(Throwable t); from Apache Commons 3 class org.apache.commons.lang3.exception.ExceptionUtils.

http://commons.apache.org/proper/commons-lang/

ExceptionUtils.getStackTrace(Throwable t)

Code example:

try {

  // your code here

} catch(Exception e) {
  String s = ExceptionUtils.getStackTrace(e);
}

If it is an update on a table all you have to do is run this update multiple times until it is affecting 0 rows.

update tableName
set colName = REPLACE(LTRIM(RTRIM(colName)), '  ', ' ')
where colName like '%  %'

The skip login has been disabled by default due to security issues. https://github.com/kubernetes/dashboard/issues/2672

in your dashboard yaml add this arg

- --enable-skip-login

to get it back

return dataSource.getParkingLots()
                 .stream()
                 .filter(parkingLot -> Objects.equals(parkingLot.getId(), id))
                 .findFirst()
                 .orElse(null);

I had to filter out only one object from a list of objects. So i used this, hope it helps.

The following code will create a list of files based on the accept method of the FileNameFilter.

List<File> list = Arrays.asList(dir.listFiles(new FilenameFilter(){
        @Override
        public boolean accept(File dir, String name) {
            return name.endsWith(".exe"); // or something else
        }}));

Well, this seems a new problem for me, using a new php server. In the past never had an issue with sessions not ending.

In a test of sessions, I setup a session, ran a session count++ and closed the session. Reloaded the page and to my surprise the variable remained.

I tried the following suggestion posted by mc10

session_destroy();
$_SESSION = array(); // Clears the $_SESSION variable

However, that did not work. I did not think it could work as the session was not active after destroying it, so I reversed it.

$_SESSION = array();
session_destroy();

That worked, reloading the page starting sessios and reviewing the set variables all showed them empty/not-set.

Really not sure why session_destroy() does not work on this PHP Version 5.3.14 server.

Don't really care as long as I know how to clear the sessions.

If you want the result as the nearest binary floating point number use float:

result = [float(x.strip(' "')) for x in A1]

If you want the result stored exactly use Decimal instead of float:

from decimal import Decimal
result = [Decimal(x.strip(' "')) for x in A1]

In Git, to "fast forward" means to update the HEAD pointer in such a way that its new value is a direct descendant of the prior value. In other words, the prior value is a parent, or grandparent, or grandgrandparent, ...

Fast forwarding is not possible when the new HEAD is in a diverged state relative to the stream you want to integrate. For instance, you are on master and have local commits, and git fetch has brought new upstream commits into origin/master. The branch now diverges from its upstream and cannot be fast forwarded: your master HEAD commit is not an ancestor of origin/master HEAD. To simply reset master to the value of origin/master would discard your local commits. The situation requires a rebase or merge.

If your local master has no changes, then it can be fast-forwarded: simply updated to point to the same commit as the latestorigin/master. Usually, no special steps are needed to do fast-forwarding; it is done by merge or rebase in the situation when there are no local commits.

Is it ok to assume that fast-forward means all commits are replayed on the target branch and the HEAD is set to the last commit on that branch?

No, that is called rebasing, of which fast-forwarding is a special case when there are no commits to be replayed (and the target branch has new commits, and the history of the target branch has not been rewritten, so that all the commits on the target branch have the current one as their ancestor.)

Using an example data.frame and example function (just +1 to all values)

A <- function(x) x + 1
wifi <- data.frame(replicate(9,1:4))
wifi

#  X1 X2 X3 X4 X5 X6 X7 X8 X9
#1  1  1  1  1  1  1  1  1  1
#2  2  2  2  2  2  2  2  2  2
#3  3  3  3  3  3  3  3  3  3
#4  4  4  4  4  4  4  4  4  4

data.frame(wifi[1:3], apply(wifi[4:9],2, A) )
#or
cbind(wifi[1:3], apply(wifi[4:9],2, A) )

#  X1 X2 X3 X4 X5 X6 X7 X8 X9
#1  1  1  1  2  2  2  2  2  2
#2  2  2  2  3  3  3  3  3  3
#3  3  3  3  4  4  4  4  4  4
#4  4  4  4  5  5  5  5  5  5

Or even:

data.frame(wifi[1:3], lapply(wifi[4:9], A) )
#or
cbind(wifi[1:3], lapply(wifi[4:9], A) )

#  X1 X2 X3 X4 X5 X6 X7 X8 X9
#1  1  1  1  2  2  2  2  2  2
#2  2  2  2  3  3  3  3  3  3
#3  3  3  3  4  4  4  4  4  4

This thread is a little old, and I am brand new to this, but I think I found the preferred solution.

First, I assume that you are using Eclipse and the Android ADT plugin.

In Eclipse, choose Window/Android SDK Manager. In the display, expand the entry for the MOST RECENT PLATFORM, even if that is not the platform that your are developing for. As of Jan 2012, it is "Android 4.0.3 (API 15)". When expanded, the first entry is "Documentation for Android SDK" Click the checkbox next to it, and then click the "Install" button.

When done, you should have a new directory in your "android-sdks" called "doc". Look for "offline.html" in there. Since this is packaged with the most recent version, it will document the most recent platform, but it should also show the APIs for previous versions.

The pipe, |, is a special-character in regex (meaning "or") and you'll have to escape it with a \.

Using your current regex:

\|.*$

I've tried this in Notepad++, as you've mentioned, and it appears to work well.

Probably because for both sides (B and C) only the type is relevant, not the implementation. In your example

public class A<B extends C>{}

B can be an interface as well. "extends" is used to define sub-interfaces as well as sub-classes.

interface IntfSub extends IntfSuper {}
class ClzSub extends ClzSuper {}

I usually think of 'Sub extends Super' as 'Sub is like Super, but with additional capabilities', and 'Clz implements Intf' as 'Clz is a realization of Intf'. In your example, this would match: B is like C, but with additional capabilities. The capabilities are relevant here, not the realization.

Yes, provided you have access to the object definition and can modify it to declare the custom event

public event EventHandler<EventArgs> ModelChanged;

And normally you'd back this up with a private method used internally to invoke the event:

private void OnModelChanged(EventArgs e)
{
    if (ModelChanged != null)
        ModelChanged(this, e);
}

Your code simply declares a handler for the declared myMethod event (you can also remove the constructor), which would get invoked every time the object triggers the event.

myObject.myMethod += myNameEvent;

Similarly, you can detach a handler using

myObject.myMethod -= myNameEvent;

Also, you can write your own subclass of EventArgs to provide specific data when your event fires.

If your listbox is connected to a LIST as the data source, listbox.Items.Clear() will not work.

I typically create a file named "DataAccess.cs" containing a separate class for code that uses or changes data pertaining to my form. The following is a code snippet from the DataAccess class that clears or removes all items in the list "exampleItems"

public List<ExampleItem> ClearExampleItems()
       {
           List<ExampleItem> exampleItems = new List<ExampleItem>();
           exampleItems.Clear();
           return examplelistItems;
        }

ExampleItem is also in a separate class named "ExampleItem.cs"

using System;

namespace        // The namespace is automatically added by Visual Studio
{
    public class ExampleItem
    {
        public int ItemId { get; set; }
        public string ItemType { get; set; }
        public int ItemNumber { get; set; }
        public string ItemDescription { get; set; }

        public string FullExampleItem 
        {
            get
            {
                return $"{ItemId} {ItemType} {ItemNumber} {ItemDescription}";
            }
        }
    }
}

In the code for your Window Form, the following code fragments reference your listbox:

using System;
using System.Collections.Generic;
using System.Configuration;
using System.Linq;
using System.Windows.Forms;

namespace        // The namespace is automatically added by Visual Studio
{
    
    public partial class YourFormName : Form
    {
        
        List<ExampleItem> exampleItems = new List<ExampleItem>();

        public YourFormName()
        {
            InitializeComponent();

            // Connect listbox to LIST
            UpdateExampleItemsBinding();
        }

        private void UpdateUpdateItemsBinding()
        {
            ExampleItemsListBox.DataSource = exampleItems;
            ExampleItemsListBox.DisplayMember = "FullExampleItem";
        }

        private void buttonClearListBox_Click(object sender, EventArgs e)
        {
            DataAccess db = new DataAccess();
            exampleItems = db.ClearExampleItems();
            
            UpdateExampleItemsBinding();
        }
    }
}

This solution specifically addresses a Windows Form listbox with the datasource connected to a list.

This is my current method of checking if Mod_rewrite enabled for both Apache and IIS

/**
 * --------------------------------------------------------------
 *  MOD REWRITE CHECK
 * --------------------------------------------------------------
 *                                        - By A H Abid
 * Define Constant for MOD REWRITE
 * 
 * Check if server allows MOD REWRITE. Checks for both 
 * Apache and IIS.
 * 
 */
if( function_exists('apache_get_modules') && in_array('mod_rewrite',apache_get_modules()) )
    $mod_rewrite = TRUE;
elseif( isset($_SERVER['IIS_UrlRewriteModule']) )
    $mod_rewrite = TRUE;
else
    $mod_rewrite = FALSE;
define('MOD_REWRITE', $mod_rewrite);

It works in my local machine and also worked in my IIS based webhost. However, on a particular apache server, it didn't worked for Apache as the apache_get_modules() was disabled but the mod_rewrite was enable in that server.

I get this a lot. I'm on a Galaxy S too. I unplug the cable from the phone, plug it back in and try launching the app again from Eclipse, and it usually does the trick. Eclipse seems to lose the connection to the phone occasionally but this seems to kick it back to life.

requests package works really well for simple ui as @Andrew Mao suggested

As an update for those who come across this question after 2018, if you are using Kotlin, you can simply use the Android KTX extension property ViewGroup.children to get a sequence of the View's immediate children.

Implementing IEnumerable means your class returns an IEnumerator object:

public class People : IEnumerable
{
    IEnumerator IEnumerable.GetEnumerator()
    {
        // return a PeopleEnumerator
    }
}

Implementing IEnumerator means your class returns the methods and properties for iteration:

public class PeopleEnumerator : IEnumerator
{
    public void Reset()...

    public bool MoveNext()...

    public object Current...
}

That's the difference anyway.

When you want to read a file with a different configuration than the default one, feel free to use either mpu.aws.s3_read(s3path) directly or the copy-pasted code:

def s3_read(source, profile_name=None):
    """
    Read a file from an S3 source.

    Parameters

    source : str
        Path starting with s3://, e.g. 's3://bucket-name/key/foo.bar'
    profile_name : str, optional
        AWS profile

    Returns
    -------
    content : bytes

    botocore.exceptions.NoCredentialsError

    session = boto3.Session(profile_name=profile_name)
    s3 = session.client('s3')
    bucket_name, key = mpu.aws._s3_path_split(source)

I get this error message and it mentions options.body

I had this originally

request.post({
    url: apiServerBaseUrl + '/v1/verify',
    body: {
        email: req.user.email
    }
});

I changed it to this:

request.post({
    url: apiServerBaseUrl + '/v1/verify',
    body: JSON.stringify({
        email: req.user.email
    })
});

and it seems to work now without the error message...seems like bug though.

I think this is the more official way to do it:

 request.post({
        url: apiServerBaseUrl + '/v1/verify',
        json: true,
        body: {
            email: req.user.email
        }
    });

I would concatenate the old list and new list as streams and save the results to destination list. Works well in parallel, too.

I will use the example of accepted answer given by Stuart Marks:

List<String> destList = Arrays.asList("foo");
List<String> newList = Arrays.asList("0", "1", "2", "3", "4", "5");

destList = Stream.concat(destList.stream(), newList.stream()).parallel()
            .collect(Collectors.toList());
System.out.println(destList);

//output: [foo, 0, 1, 2, 3, 4, 5]

Hope it helps.

I just want to fill only 80% of the screen for that I did like this below

        DisplayMetrics metrics = getResources().getDisplayMetrics();
        int screenWidth = (int) (metrics.widthPixels * 0.80);

        setContentView(R.layout.mylayout);

        getWindow().setLayout(screenWidth, LayoutParams.WRAP_CONTENT); //set below the setContentview

it works only when I put the getwindow().setLayout... line below the setContentView(..)

thanks @Matthias

None of the posted answers worked for me, so I reinstalled pip and it worked!

sudo apt-get install python-setuptools python-dev build-essential 

sudo easy_install pip 

pip install --upgrade setuptools

(reference: http://www.saltycrane.com/blog/2010/02/how-install-pip-ubuntu/)

Depending on what I'm using it for, or if I'm doing something that others will use, I typically just input("Do eighteen backflips to continue") if it's just for me, if others will be using I just create a batch file and pause it after

cd '/file/path/here'
python yourfile.py
pause 

I use the above if there is going to be files renamed, moved, copied, etc. and my cmd needs to be in the particular folder for things to fall where I want them, otherwise - just

python '/path/to/file/yourfile.py'
pause

public static LocalDate Date2LocalDate(Date date) {
        return LocalDate.parse(date.toString(), DateTimeFormatter.ofPattern("EEE MMM dd HH:mm:ss zzz yyyy"))

this format is from Date#tostring

    public String toString() {
        // "EEE MMM dd HH:mm:ss zzz yyyy";
        BaseCalendar.Date date = normalize();
        StringBuilder sb = new StringBuilder(28);
        int index = date.getDayOfWeek();
        if (index == BaseCalendar.SUNDAY) {
            index = 8;
        }
        convertToAbbr(sb, wtb[index]).append(' ');                        // EEE
        convertToAbbr(sb, wtb[date.getMonth() - 1 + 2 + 7]).append(' ');  // MMM
        CalendarUtils.sprintf0d(sb, date.getDayOfMonth(), 2).append(' '); // dd

        CalendarUtils.sprintf0d(sb, date.getHours(), 2).append(':');   // HH
        CalendarUtils.sprintf0d(sb, date.getMinutes(), 2).append(':'); // mm
        CalendarUtils.sprintf0d(sb, date.getSeconds(), 2).append(' '); // ss
        TimeZone zi = date.getZone();
        if (zi != null) {
            sb.append(zi.getDisplayName(date.isDaylightTime(), TimeZone.SHORT, Locale.US)); // zzz
        } else {
            sb.append("GMT");
        }
        sb.append(' ').append(date.getYear());  // yyyy
        return sb.toString();
    }

And if you do that very often, you could use a ViewSwitcher or a ViewFlipper to ease view substitution.

An approach that solves both decimal and Int:

 func textField(_ textField: UITextField, shouldChangeCharactersIn range: NSRange, replacementString string: String) -> Bool {
    let currentText = textField.text
    let futureString = currentText.substring(toIndex: range.location) + string + currentText.substring(fromIndex: range.location + range.length)
    
    if futureString.count == 0 {
        return true
    }
    
    if isDecimal {
        if let numberAsDouble = Double(futureString), numberAsDouble.asPrice.count >= futureString.count {
            return true
        }
    } else if let numberAsInt = Int(futureString), "\(numberAsInt)".count == futureString.count {
        return true
    }
    
    return false
}

consider $any()

<textarea (keyup)="emitWordCount($any($event))"></textarea>

list1 = ['a','b','c','d','e','f','g','h','i']
list2 = [0,1,1,0,1,2,2,0,1]

output=[]
cur_loclist = []

To get unique values present in list2

list_set = set(list2)

To find the loc of the index in list2

list_str = ''.join(str(s) for s in list2)

Location of index in list2 is tracked using cur_loclist

[0, 3, 7, 1, 2, 4, 8, 5, 6]

for i in list_set:
cur_loc = list_str.find(str(i))

while cur_loc >= 0:
    cur_loclist.append(cur_loc)
    cur_loc = list_str.find(str(i),cur_loc+1)

print(cur_loclist)

for i in range(0,len(cur_loclist)):
output.append(list1[cur_loclist[i]])
print(output)

To solve the issue you must assign the proper ownership permissions. Try the below which should resolve all permission related issues for specific users but as stated in the comments this should not be used in production:

root@server:/var/log/postgresql# sudo -u postgres psql
psql (8.4.4)
Type "help" for help.

postgres=# \du
               List of roles
    Role name    | Attributes  | Member of
-----------------+-------------+-----------
 <user-name>    | Superuser   | {}
                 : Create DB
 postgres       | Superuser   | {}
                 : Create role
                 : Create DB

postgres=# alter role <user-name> superuser;
ALTER ROLE
postgres=#

So connect to the database under a Superuser account sudo -u postgres psql and execute a ALTER ROLE <user-name> Superuser; statement.

Keep in mind this is not the best solution on multi-site hosting server so take a look at assigning individual roles instead: https://www.postgresql.org/docs/current/static/sql-set-role.html and https://www.postgresql.org/docs/current/static/sql-alterrole.html.

I solved this problem today by altering the column to 'LONGBLOB' type which stores raw bytes instead of UTF-8 characters.

The only disadvantage of doing this is that you have to take care of the encoding yourself. If one client of your application uses UTF-8 encoding and another uses CP1252, you may have your emails sent with incorrect characters. To avoid this, always use the same encoding (e.g. UTF-8) across all your applications.

Refer to this page http://dev.mysql.com/doc/refman/5.0/en/blob.html for more details of the differences between TEXT/LONGTEXT and BLOB/LONGBLOB. There are also many other arguments on the web discussing these two.

You can align text anywhere in the scaffold or container except center:-

Its works for me anywhere in my application:-

new Text(

                "Nextperience",

//i have setted in center.

                textAlign: TextAlign.center,

//when i want it left.

 //textAlign: TextAlign.left,

//when i want it right.

 //textAlign: TextAlign.right,

                style: TextStyle(

                    fontSize: 16,

                    color: Colors.blue[900],

                    fontWeight: FontWeight.w500),

              ), 

Override using JavaScript

$('.mytable td').attr('style', 'display: none !important');

Worked for me.

simple one-liner starts with a default min-height and increases to contents size.

<iframe src="http://url.html" onload='javascript:(function(o){o.style.height=o.contentWindow.document.body.scrollHeight+"px";}(this));' style="height:200px;width:100%;border:none;overflow:hidden;"></iframe>
