To remove a timezone (tzinfo) from a datetime object:

# dt_tz is a datetime.datetime object
dt = dt_tz.replace(tzinfo=None)

If you are using a library like arrow, then you can remove timezone by simply converting an arrow object to to a datetime object, then doing the same thing as the example above.

# <Arrow [2014-10-09T10:56:09.347444-07:00]>
arrowObj = arrow.get('2014-10-09T10:56:09.347444-07:00')

# datetime.datetime(2014, 10, 9, 10, 56, 9, 347444, tzinfo=tzoffset(None, -25200))
tmpDatetime = arrowObj.datetime

# datetime.datetime(2014, 10, 9, 10, 56, 9, 347444)
tmpDatetime = tmpDatetime.replace(tzinfo=None)

Why would you do this? One example is that mysql does not support timezones with its DATETIME type. So using ORM's like sqlalchemy will simply remove the timezone when you give it a datetime.datetime object to insert into the database. The solution is to convert your datetime.datetime object to UTC (so everything in your database is UTC since it can't specify timezone) then either insert it into the database (where the timezone is removed anyway) or remove it yourself. Also note that you cannot compare datetime.datetime objects where one is timezone aware and another is timezone naive.

# MySQL example! where MySQL doesn't support timezones with its DATETIME type!
##############################################################################

arrowObj = arrow.get('2014-10-09T10:56:09.347444-07:00')

arrowDt = arrowObj.to("utc").datetime

# inserts datetime.datetime(2014, 10, 9, 17, 56, 9, 347444, tzinfo=tzutc())
insertIntoMysqlDatabase(arrowDt)

# returns datetime.datetime(2014, 10, 9, 17, 56, 9, 347444)
dbDatetimeNoTz = getFromMysqlDatabase()

# cannot compare timzeone aware and timezone naive
dbDatetimeNoTz == arrowDt # False, or TypeError on python versions before 3.3

# compare datetimes that are both aware or both naive work however
dbDatetimeNoTz == arrowDt.replace(tzinfo=None) # True

Available from Python3.9:

zoneinfo,new module in Python3.9 which works against the database of IANA. In order to grab all the available timezones, first:

pip install tzdata

And then:

import zoneinfo

print(zoneinfo.available_timezones())

public static int getRandom(int[] array) {
    int rnd = new Random().nextInt(array.length);
    return array[rnd];
}

git diff --name-only SHA1 SHA2

where you only need to include enough of the SHA to identify the commits. You can also do, for example

git diff --name-only HEAD~10 HEAD~5

to see the differences between the tenth latest commit and the fifth latest (or so).

Simplest solution:

Convert array to list and you can get position of an element.

List<String> abcd  = Arrays.asList(yourArray);
int i = abcd.indexOf("abcd");

Other solution, you can iterator array:

int position = 0;
for (String obj : yourArray) {
    if (obj.equals("abcd") {
    return position;
    }
    position += 1;
} 

//OR
for (int i = 0; i < yourArray.length; i++) {
    if (obj.equals("abcd") {
       return i;
    }
}

The top answer is great.

I would just add, that it becomes easy to understand if you think about remotes as locations other than your computer that you may want to move your code to.

Some very good examples are:

• GitHub
• A server to host your app

So you can certainly have multiple remotes. A very common pattern is to use GitHub to store your code, and a server to host your application (if it's a web application). Then you would have 2 remotes (possibly more if you have other environments).

Try opening your git config by typing git config -e

Note: press escape, then :, then q then enter to quit out

Example

Here's what you might see in your git configs if you had 3 remotes. In this example, 1 remote (called 'origin') is GitHub, another remote (called 'staging') is a staging server, and the third (called 'heroku') is a production server.

[core]
        repositoryformatversion = 0
        filemode = true
        bare = false
        logallrefupdates = true
        ignorecase = true
        precomposeunicode = true
[remote "origin"]
        url = https://github.com/username/reponame.git
        fetch = +refs/heads/*:refs/remotes/origin/*
[branch "master"]
        remote = origin
        merge = refs/heads/master
[remote "heroku"]
        url = https://git.heroku.com/appname.git
        fetch = +refs/heads/*:refs/remotes/heroku/*
[remote "staging"]
        url = https://git.heroku.com/warm-bedlands-98000.git
        fetch = +refs/heads/*:refs/remotes/staging/*

The three lines starting with [remote ... show us the remotes we can push to.

Running git push origin will push to the url for '[remote "origin"]', i.e. to GitHub

But similarly, we could push to another remote, say, '[remote "staging"]', with git push staging, then it would push to https://git.heroku.com/warm-bedlands-98000.git.

In the example above, we can see the 3 remotes with git remote:

git remote   
heroku
origin
staging

Summary or origin

Remotes are simply places on the internet that you may have a reason to send your code to. GitHub is an obvious place, as are servers that host your app, and you may have other locations too. git push origin simply means it will push to 'origin', which is the name GitHub chooses to default to.

As for branchname

branchname is simply what you're pushing to the remote. According the git push help docs, the branchname argument is technically a refspec, which, for practical purposes, is the branch you want to push.

• Read more in the docs for git push by running: git push --help

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

ALTER PROCEDURE dbo.spTEST
AS
    SET NOCOUNT ON
    DECLARE @query NVARCHAR(4000) = N'' --DATA FILTER
    DECLARE @inputList NVARCHAR(4000) = ''
    DECLARE @field sysname = '' --COLUMN NAME
    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

Should be:

What worked for me on Lion was installing the JDK7_u17 from Oracle, then editing ~/.bash_profile to include: export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_13.jdk/Contents/Home

Your code is fine. In case you're not sure how to use Calculate function, try

Calculate(5,5,(Operator)0); //this will add 5,5
Calculate(5,5,Operator.PLUS);// alternate

Default enum values start from 0 and increase by one for following elements, until you assign different values. Also you can do :

public enum Operator{PLUS=21,MINUS=345,MULTIPLY=98,DIVIDE=100};

Object.keys(city)[0];   //return the key name at index 0
Object.values(city)[0]  //return the key values at index 0

Do you have a "shared object" (usually a shared library on AIX), a UNIX shared library, or a Windows DLL? These are all different things, and your question conflates them all :-(

• For an AIX shared object, use dump -Tv /path/to/foo.o.
• For an ELF shared library, use readelf -Ws /path/to/libfoo.so, or (if you have GNU nm) nm -D /path/to/libfoo.so.
• For a non-ELF UNIX shared library, please state which UNIX you are interested in.
• For a Windows DLL, use dumpbin /EXPORTS foo.dll.

If you're printing to stdout, it depends on the terminal you're printing to. You can use ansi escape codes on xterms and other similar terminal emulators. Here's a bash code snippet that will print all 255 colors supported by xterm, putty and Konsole:

 for ((i=0;i<256;i++)); do echo -en "\e[38;5;"$i"m"$i" "; done

You can use these escape codes in any programming language. It's better to rely on a library that will decide which codes to use depending on architecture and the content of the TERM environment variable.

If you are using the animation listener, set v.setAnimationListener(null). Use the following code with all options.

v.getAnimation().cancel();
v.clearAnimation();
animation.setAnimationListener(null);

This code works fine on iPhone under iOS6 and iOS7:

presentedVC.view.backgroundColor = YOUR_COLOR; // can be with 'alpha'
presentingVC.modalPresentationStyle = UIModalPresentationCurrentContext;
[presentingVC presentViewController:presentedVC animated:YES completion:NULL];

In this case you miss slide-on animation. To retain animation you still can use the following "non-elegant" extension:

[presentingVC presentViewController:presentedVC animated:YES completion:^{
    [presentedVC dismissViewControllerAnimated:NO completion:^{
        presentingVC.modalPresentationStyle = UIModalPresentationCurrentContext;
        [presentingVC presentViewController:presentedVC animated:NO completion:NULL];
    }];
}];

If our presentingV is located inside of UINavigationController or UITabbarController you need to operate with that controllers as presentingVC.

Further, in iOS7 you can implement custom transition animation applying UIViewControllerTransitioningDelegate protocol. Of course, in this case you can get transparent background

@interface ModalViewController : UIViewController <UIViewControllerTransitioningDelegate>

First, before presenting you have to set modalPresentationStyle

modalViewController.modalPresentationStyle = UIModalPresentationCustom;

Then you have to implement two protocol methods

- (id<UIViewControllerAnimatedTransitioning>)animationControllerForPresentedController:(UIViewController *)presented presentingController:(UIViewController *)presenting sourceController:(UIViewController *)source
{
    CustomAnimatedTransitioning *transitioning = [CustomAnimatedTransitioning new];
    transitioning.presenting = YES;
    return transitioning;
}

- (id<UIViewControllerAnimatedTransitioning>)animationControllerForDismissedController:(UIViewController *)dismissed
{
    CustomAnimatedTransitioning * transitioning = [CustomAnimatedTransitioning new];
    transitioning.presenting = NO;
    return transitioning;
}

The last thing is to define your custom transition in CustomAnimatedTransitioning class

@interface CustomAnimatedTransitioning : NSObject <UIViewControllerAnimatedTransitioning>
@property (nonatomic) BOOL presenting;
@end

@implementation CurrentContextTransitionAnimator

- (NSTimeInterval)transitionDuration:(id <UIViewControllerContextTransitioning>)transitionContext 
{
    return 0.25;
}

- (void)animateTransition:(id <UIViewControllerContextTransitioning>)transitionContext 
{
    UIViewController *fromViewController = [transitionContext viewControllerForKey:UITransitionContextFromViewControllerKey];
    UIViewController *toViewController = [transitionContext viewControllerForKey:UITransitionContextToViewControllerKey];

    if (self.presenting) {
        // custom presenting animation
    }
    else {
        // custom dismissing animation
    }
}

I faced the same problem after migrating a database from online server to localhost. The schema changed so I had to define the schema manually for each table:

@Entity
@Table(name = "ESBCORE_DOMAIN", schema = "SYS")

For those of us who have a github.com account, but only get a nasty error message when we type "git" into the command-line, here's how to do it all in your browser :)

1. Same as Tim and Farhan wrote: Fork your own copy of the project:
2. After a few seconds, you'll be redirected to your own forked copy of the project:
3. Navigate to the file(s) you need to change and click "Edit this file" in the toolbar:
4. After editing, write a few words describing the changes and then "Commit changes", just as well to the master branch (since this is only your own copy and not the "main" project).
5. Repeat steps 3 and 4 for all files you need to edit, and then go back to the root of your copy of the project. There, click the green "Compare, review..." button:
6. Finally, click "Create pull request" ..and then "Create pull request" again after you've double-checked your request's heading and description:

A solution could be to use a local file which retrieves the remote content

remoteInclude.php

<?php
$url = $_GET['url'];
$contents = file_get_contents($url);
echo $contents;

The HTML

<iframe frameborder="1" id="frametest" src="/remoteInclude.php?url=REMOTE_URL_HERE"></iframe>
<script>
    $("#frametest").load(function (){       
    var contents =$("#frametest").contents();
});

public string GetDomainName<T>()
{
    var dnAttribute = typeof(T).GetCustomAttributes(
        typeof(DomainNameAttribute), true
    ).FirstOrDefault() as DomainNameAttribute;
    if (dnAttribute != null)
    {
        return dnAttribute.Name;
    }
    return null;
}

UPDATE:

This method could be further generalized to work with any attribute:

public static class AttributeExtensions
{
    public static TValue GetAttributeValue<TAttribute, TValue>(
        this Type type, 
        Func<TAttribute, TValue> valueSelector) 
        where TAttribute : Attribute
    {
        var att = type.GetCustomAttributes(
            typeof(TAttribute), true
        ).FirstOrDefault() as TAttribute;
        if (att != null)
        {
            return valueSelector(att);
        }
        return default(TValue);
    }
}

and use like this:

string name = typeof(MyClass)
    .GetAttributeValue((DomainNameAttribute dna) => dna.Name);

Since many people are probably viewing this answer when searching for log4j2 and nearly all current answers do not consider log4j2 or recent changes in it, this should hopefully answer the question.

log4j2 supports Suppliers (currently their own implementation, but according to the documentation it is planned to use Java's Supplier interface in version 3.0). You can read a little bit more about this in the manual. This allows you to put expensive log message creation into a supplier which only creates the message if it is going to be logged:

LogManager.getLogger().debug(() -> createExpensiveLogMessage());

You can't. A redirect requires a webserver to accept the first request and send back the redirect. The "hosts" file just lets you set your own DNS records.

If you need to sort by only one field, then usort is a good choice. However, the solution quickly becomes messy if you need to sort by multiple fields. In this case, YaLinqo library* can be used, which implements SQL-like query syntax for arrays and objects. It has a pretty syntax for all cases:

$sortedByName         = from($objects)->orderBy('$v->name');
$sortedByCount        = from($objects)->orderBy('$v->count');
$sortedByCountAndName = from($objects)->orderBy('$v->count')->thenBy('$v->name');

Here, '$v->count' is a shorthand for function ($v) { return $v->count; } (either can be used). These method chains return iterators, but you can get arrays by adding ->toArray() in the end if you need it.

_{* developed by me}

From jQuery's website

Shorthand CSS properties (e.g. margin, background, border) are not supported. For example, if you want to retrieve the rendered margin, use: $(elem).css('marginTop') and $(elem).css('marginRight'), and so on.

Object doesn't support this property or method.

Think of it like if anything after the dot is called on an object. It's like a chain.

An object is a class instance. A class instance supports some properties defined in that class type definition. It exposes whatever intelli-sense in VBE tells you (there are some hidden members but it's not related to this). So after each dot . you get intelli-sense (that white dropdown) trying to help you pick the correct action.

(you can start either way - front to back or back to front, once you understand how this works you'll be able to identify where the problem occurs)

Type this much anywhere in your code area

Dim a As Worksheets
a.

you get help from VBE, it's a little dropdown called Intelli-sense

It lists all available actions that particular object exposes to any user. You can't see the .Selection member of the Worksheets() class. That's what the error tells you exactly.

Object doesn't support this property or method.

If you look at the example on MSDN

Worksheets("GRA").Activate
iAreaCount = Selection.Areas.Count

It activates the sheet first then calls the Selection... it's not connected together because Selection is not a member of Worksheets() class. Simply, you can't prefix the Selection

What about

Sub DisplayColumnCount()
    Dim iAreaCount As Integer
    Dim i As Integer

    Worksheets("GRA").Activate
    iAreaCount = Selection.Areas.Count

    If iAreaCount <= 1 Then
        MsgBox "The selection contains " & Selection.Columns.Count & " columns."
    Else
        For i = 1 To iAreaCount
        MsgBox "Area " & i & " of the selection contains " & _
        Selection.Areas(i).Columns.Count & " columns."
        Next i
    End If
End Sub

Yes we can check the length of queue object created from collections.

from collections import deque
class Queue():
    def __init__(self,batchSize=32):
        #self.batchSie = batchSize
        self._queue = deque(maxlen=batchSize)

    def enqueue(self, items):
        ''' Appending the items to the queue'''
        self._queue.append(items)

    def dequeue(self):
        '''remoe the items from the top if the queue becomes full '''
        return self._queue.popleft()

Creating an object of class

q = Queue(batchSize=64)
q.enqueue([1,2])
q.enqueue([2,3])
q.enqueue([1,4])
q.enqueue([1,22])

Now retrieving the length of the queue

#check the len of queue
print(len(q._queue)) 
#you can print the content of the queue
print(q._queue)
#Can check the content of the queue
print(q.dequeue())
#Check the length of retrieved item 
print(len(q.dequeue()))

check the results in attached screen shot

Hope this helps...

Don't hesitate to watch heap to see memory leaks in event handlers keeping a reference to the element with a closure and the element keeping a reference to the event handler.

Garbage collector do not like circular references.

Usual memory leak case: admit an object has a ref to an element. That element has a ref to the handler. And the handler has a ref to the object. The object has refs to a lot of other objects. This object was part of a collection you think you have thrown away by unreferencing it from your collection. => the whole object and all it refers will remain in memory till page exit. => you have to think about a complete killing method for your object class or trust a mvc framework for example.

Moreover, don't hesitate to use the Retaining tree part of Chrome dev tools.

You can use these options as well, either use \footnotesize or \tiny. This would really help in fitting big tables.

\begin{table}[htbp]
\footnotesize
\caption{Information on making the table size small}
\label{table:table1}
\begin{tabular}{ll}
    \toprule
    S.No       & HMD           \\
    \midrule
    1          & HTC Vive \\
    2          & HTC Vive Pro   \\
    \bottomrule
\end{tabular}
\end{table}

The SQL WITH clause was introduced by Oracle in the Oracle 9i release 2 database. The SQL WITH clause allows you to give a sub-query block a name (a process also called sub-query refactoring), which can be referenced in several places within the main SQL query. The name assigned to the sub-query is treated as though it was an inline view or table. The SQL WITH clause is basically a drop-in replacement to the normal sub-query.

Syntax For The SQL WITH Clause

The following is the syntax of the SQL WITH clause when using a single sub-query alias.

WITH <alias_name> AS (sql_subquery_statement)
SELECT column_list FROM <alias_name>[,table_name]
[WHERE <join_condition>]

When using multiple sub-query aliases, the syntax is as follows.

WITH <alias_name_A> AS (sql_subquery_statement),
<alias_name_B> AS(sql_subquery_statement_from_alias_name_A
or sql_subquery_statement )
SELECT <column_list>
FROM <alias_name_A>, <alias_name_B> [,table_names]
[WHERE <join_condition>]

In the syntax documentation above, the occurrences of alias_name is a meaningful name you would give to the sub-query after the AS clause. Each sub-query should be separated with a comma Example for WITH statement. The rest of the queries follow the standard formats for simple and complex SQL SELECT queries.

For more information: http://www.brighthub.com/internet/web-development/articles/91893.aspx

Continuing from Pete's example above, to do it directly in the cmd window, use a single %, eg:

cd c:\test\folder A
for %X in (*)do echo %~nxX

(Note that special files like desktop.ini will not show up.)

It's also possible to redirect the output to a file using >>:

cd c:\test\folder A
for %X in (*)do echo %~nxX>>c:\test\output.txt

For a real example, assuming you want to robocopy all files from folder-A to folder-B (non-recursively):

cd c:\test\folder A
for %X in (*)do robocopy . "c:\test\folder B" "%~nxX" /dcopy:dat /copyall /v>>c:\test\output.txt

and for all folders (recursively):

cd c:\test\folder A
for /d %X in (*)do robocopy "%X" "C:\test\folder B\%X" /e /copyall /dcopy:dat /v>>c:\test\output2.txt

If you are using PHP version 5.3 or higher you can do the following:

$host= gethostname();
$ip = gethostbyname($host);

This works well when you are running a stand-alone script, not running through the web server.

Here's my step in Ubuntu 16.04 and Tomcat 8.

1. Copy folder /var/lib/tomcat8/webapps/ROOT to your folder.

   cp -r /var/lib/tomcat8/webapps/ROOT /var/lib/tomcat8/webapps/{yourfolder}

2. Add your html, css, js, to your folder.

3. Open "http://localhost:8080/{yourfolder}" in browser

Notes:

1. If you using chrome web browser and did wrong folder before, then clean web browser's cache(or change another name) otherwise (sometimes) it always 404.

2. The folder META-INF with context.xml is needed.

I faced this issue on chrome before and the cause for it is that there was a div has min-height set to a value. The solution was to reset min-height while printing as follows:

@media print {
    .wizard-content{
        min-height: 0;
    }
}

Use the modern version of the Fisher–Yates shuffle algorithm:

/**
 * Shuffles array in place.
 * @param {Array} a items An array containing the items.
 */
function shuffle(a) {
    var j, x, i;
    for (i = a.length - 1; i > 0; i--) {
        j = Math.floor(Math.random() * (i + 1));
        x = a[i];
        a[i] = a[j];
        a[j] = x;
    }
    return a;
}

ES2015 (ES6) version

/**
 * Shuffles array in place. ES6 version
 * @param {Array} a items An array containing the items.
 */
function shuffle(a) {
    for (let i = a.length - 1; i > 0; i--) {
        const j = Math.floor(Math.random() * (i + 1));
        [a[i], a[j]] = [a[j], a[i]];
    }
    return a;
}

Note however, that swapping variables with destructuring assignment causes significant performance loss, as of October 2017.

Use

var myArray = ['1','2','3','4','5','6','7','8','9'];
shuffle(myArray);

Implementing prototype

Using Object.defineProperty (method taken from this SO answer) we can also implement this function as a prototype method for arrays, without having it show up in loops such as for (i in arr). The following will allow you to call arr.shuffle() to shuffle the array arr:

Object.defineProperty(Array.prototype, 'shuffle', {
    value: function() {
        for (let i = this.length - 1; i > 0; i--) {
            const j = Math.floor(Math.random() * (i + 1));
            [this[i], this[j]] = [this[j], this[i]];
        }
        return this;
    }
});

It seems that there is a typo, since 1104*1104*50=60940800 and you are trying to reshape to dimensions 50,1104,104. So it seems that you need to change 104 to 1104.

Omitting the html, head, and body tags is certainly allowed by the HTML specs. The underlying reason is that browsers have always sought to be consistent with existing web pages, and the very early versions of HTML didn't define those elements. When HTML 2.0 first did, it was done in a way that the tags would be inferred when missing.

I often find it convenient to omit the tags when prototyping and especially when writing test cases as it helps keep the mark-up focused on the test in question. The inference process should create the elements in exactly the manner that you see in Firebug, and browsers are pretty consistent in doing that.

But...

IE has at least one known bug in this area. Even IE9 exhibits this. Suppose the markup is this:

<!DOCTYPE html>
<title>Test case</title>
<form action='#'>
   <input name="var1">
</form>

You should (and do in other browsers) get a DOM that looks like this:

HTML
    HEAD
        TITLE
    BODY
        FORM action="#"
            INPUT name="var1"

But in IE you get this:

HTML
    HEAD
       TITLE
       FORM action="#"
           BODY
               INPUT name="var1"
    BODY

See it for yourself.

This bug seems limited to the form start tag preceding any text content and any body start tag.

You can create subset of data with your condition and then use shape or len:

print df
  col1 education

2    c       8th

print df.education == '9th'

print df[df.education == '9th']
  col1 education

print df[df.education == '9th'].shape[0]

print len(df[df['education'] == '9th'])

Performance is interesting, the fastest solution is compare numpy array and sum:

Code:

import perfplot, string
np.random.seed(123)


def shape(df):
    return df[df.education == 'a'].shape[0]

def len_df(df):
    return len(df[df['education'] == 'a'])

def query_count(df):
    return df.query('education == "a"').education.count()

def sum_mask(df):
    return (df.education == 'a').sum()

def sum_mask_numpy(df):
    return (df.education.values == 'a').sum()

def make_df(n):
    L = list(string.ascii_letters)
    df = pd.DataFrame(np.random.choice(L, size=n), columns=['education'])
    return df

perfplot.show(
    setup=make_df,
    kernels=[shape, len_df, query_count, sum_mask, sum_mask_numpy],
    n_range=[2**k for k in range(2, 25)],
    logx=True,
    logy=True,
    equality_check=False, 
    xlabel='len(df)')

You are using datetimepicker when it should be datepicker. As per the docs. Try this and it should work.

<script type="text/javascript">
  $(function () {
    $('#datetimepicker9').datepicker({
      viewMode: 'years'
    });
  });
 </script>

Winnovative offer a .Net PDF library that supports HTML input. They offer an unlimited free trial. Depending on how you wish to deploy your project, this might be sufficient.

There's an error in your code. You're using a mix of full syntax and shorthand notation on the background-image property.This is causing the no-repeat to be ignored, since it's not a valid value for the background-image property.

body{   
    background-position:center;
    background-image:url(../images/images2.jpg) no-repeat;
}

Should become one of the following:

body{
    background:url(../images/images2.jpg) center center no-repeat;
}

or

body
{
    background-image: url(path-to-file/img.jpg);
    background-repeat:no-repeat;
    background-position: center center;
}

EDIT: For your image 'scaling' issue, you might want to look at this question's answer.

So there might be a few things wrong here.

First start by reading how to use XMLHttpRequest.open() because there's a third optional parameter for specifying whether to make an asynchronous request, defaulting to true. That means you're making an asynchronous request and need to specify a callback function before you do the send(). Here's an example from MDN:

var oXHR = new XMLHttpRequest();

oXHR.open("GET", "http://www.mozilla.org/", true);

oXHR.onreadystatechange = function (oEvent) {
    if (oXHR.readyState === 4) {
        if (oXHR.status === 200) {
          console.log(oXHR.responseText)
        } else {
           console.log("Error", oXHR.statusText);
        }
    }
};

oXHR.send(null);

Second, since you're getting a 101 error, you might use the wrong URL. So make sure that the URL you're making the request with is correct. Also, make sure that your server is capable of serving your quiz.xml file.

You'll probably have to debug by simplifying/narrowing down where the problem is. So I'd start by making an easy synchronous request so you don't have to worry about the callback function. So here's another example from MDN for making a synchronous request:

var request = new XMLHttpRequest();
request.open('GET', 'file:///home/user/file.json', false); 
request.send(null);

if (request.status == 0)
    console.log(request.responseText);

Also, if you're just starting out with Javascript, you could refer to MDN for Javascript API documentation/examples/tutorials.

document.addEventListener('scroll', function (event) {
    if ((<HTMLInputElement>event.target).id === 'latest-div') { // or any other filtering condition
  
    }
}, true /*Capture event*/);

You can use this to capture an event and and here "latest-div" is the id name so u can capture all scroller action here based on the id you can do the action as well inside here.

You cant add add items in string array more than its size, i'll suggest you to use ArrayList you can add items dynamically at run time in arrayList if you feel any problem you can freely ask

C++11 allows you to do:

for (const auto& kv : myMap) {
    std::cout << kv.first << " has value " << kv.second << std::endl;
}

C++17 allows you to do:

for (const auto& [key, value] : myMap) {
    std::cout << key << " has value " << value << std::endl;
}

using structured binding.

UPDATE:

const auto is safer if you don't want to modify the map.

This is a fiddle I always use with my Web applications:

$('body').on('dragstart drop', function(e){
    e.preventDefault();
    return false;
});

It will prevent anything on your app being dragged and dropped. Depending on tour needs, you can replace body selector with any container that childrens should not be dragged.

You might be interested in the fact that as of matplotlib version 2.1 the second code from the question works fine as well.

From the change log:

Figure class now has subplots method The Figure class now has a subplots() method which behaves the same as pyplot.subplots() but on an existing figure.

Example:

import matplotlib.pyplot as plt

fig = plt.figure()
axes = fig.subplots(nrows=2, ncols=2)

plt.show()

For 1-hot-encoding

   one_hot_encode=pandas.get_dummies(array)

Png files can handle transparency. So you could use this question Save plot to image file instead of displaying it using Matplotlib so as to save you graph as a png file.

And if you want to turn all white pixel transparent, there's this other question : Using PIL to make all white pixels transparent?

If you want to turn an entire area to transparent, then there's this question: And then use the PIL library like in this question Python PIL: how to make area transparent in PNG? so as to make your graph transparent.

Very probable that your VISUAL environment variable is set to something else. Try:

export VISUAL=vi

I need this so often that I created a function in my ~/.bashrc file:

chmodf() {
        find $2 -type f -exec chmod $1 {} \;
}
chmodd() {
        find $2 -type d -exec chmod $1 {} \;
}

Now I can use these shortcuts:

chmodd 0775 .
chmodf 0664 .

I will add an option to VitalyB's answer:

Option 3

Via npm. If you run your commands via npm, then you could add this setup to your package.json (check out also the webpack.config.js there too). For developing run npm start, no need to copy index.html in this case because the web server will be run from the source files directory, and the bundle.js will be available from the same place (the bundle.js will live in memory only but will available as if it was located together with index.html). For production run npm run build and a dist folder will contain your bundle.js and index.html gets copied with good old cp-command, as you can see below:

"scripts": {
    "test": "NODE_ENV=test karma start",
    "start": "node node_modules/.bin/webpack-dev-server --content-base app",
    "build": "NODE_ENV=production node node_modules/.bin/webpack && cp app/index.html dist/index.html"
  }

Update: Option 4

There is a copy-webpack-plugin, as described in this Stackoverflow answer

But generally, except for the very "first" file (like index.html) and larger assets (like large images or video), include the css, html, images and so on directly in your app via require and webpack will include it for you (well, after you set it up correctly with loaders and possibly plugins).

Use the gca ("get current axes") helper function:

ax = plt.gca()

Example:

import matplotlib.pyplot as plt
import matplotlib.finance
quotes = [(1, 5, 6, 7, 4), (2, 6, 9, 9, 6), (3, 9, 8, 10, 8), (4, 8, 8, 9, 8), (5, 8, 11, 13, 7)]
ax = plt.gca()
h = matplotlib.finance.candlestick(ax, quotes)
plt.show()

$(window).height();   // returns height of browser viewport
$(document).height(); // returns height of HTML document

As documented here: http://api.jquery.com/height/

In addition to what @abarnert said, I today had to find out that the default cpio utility on Mountain Lion uses a different archive format per default (not sure which), even with the man page stating it would use the old cpio/odc format. So, if anyone stumbles upon the cpio read error: bad file format message while trying to install his/her manipulated packages, be sure to include the format in the re-pack step:

find ./Foo.app | cpio -o --format odc | gzip -c > Payload

if your wanting to use jQuery for this, try the following code.

$('select option[value="1"]').attr("selected",true);

Updated:

Following a comment from Vivek, correctly pointed out steven spielberg wanted to select the option via its Text value.

Here below is the updated code.

$('select option:contains("it\'s me")').prop('selected',true);

You need to use the :contains(text) selector to find via the containing text.

Also jQuery prop offeres better support for Internet Explorer when getting and setting attributes.

A working example on JSFiddle

I forked the script above from Marcus Ekwall: https://gist.github.com/3945316 and tweaked it to my preferences, it now fires when the window is resized, so that the child always fits its container. I've pasted the script below for reference.

(function($) {
    $.fn.textfill = function(maxFontSize) {
        maxFontSize = parseInt(maxFontSize, 10);
        return this.each(function(){
            var ourText = $("span", this);
            function resizefont(){
                var parent = ourText.parent(),
                maxHeight = parent.height(),
                maxWidth = parent.width(),
                fontSize = parseInt(ourText.css("fontSize"), 10),
                multiplier = maxWidth/ourText.width(),
                newSize = (fontSize*(multiplier));
                ourText.css("fontSize", maxFontSize > 0 && newSize > maxFontSize ? maxFontSize : newSize );
            }
            $(window).resize(function(){
                resizefont();
            });
            resizefont();
        });
    };
})(jQuery);

@Clovis Six thank for your answer. It prove very usefull to me. A pity I cannot thanks you more than just a vote up.

Note: I have to change the "$J(" for "$(" for it to work on my config.

evendo, this out of the scope of this question and not in the use of SO, I extended your code to make it work for multi-line box with max-height.

  /**
   * Adjust the font-size of the text so it fits the container
   *
   * support multi-line, based on css 'max-height'.
   * 
   * @param minSize     Minimum font size?
   * @param maxSize     Maximum font size?
   */
  $.fn.autoTextSize_UseMaxHeight = function(minSize, maxSize) {
    var _self = this,
        _width = _self.innerWidth(),
        _boxHeight = parseInt(_self.css('max-height')),
        _textHeight = parseInt(_self.getTextHeight(_width)),
        _fontSize = parseInt(_self.css('font-size'));

    while (_boxHeight < _textHeight || (maxSize && _fontSize > parseInt(maxSize))) {
      if (minSize && _fontSize <= parseInt(minSize)) break;

      _fontSize--;
      _self.css('font-size', _fontSize + 'px');

      _textHeight = parseInt(_self.getTextHeight(_width));
    }
  };

PS: I know this should be a comment, but comments don't let me post code properly.

With resources, there's built-in support for providing alternatives for different languages, OS versions, screen orientations, etc., as described here. None of that is available with assets. Also, many parts of the API support the use of resource identifiers. Finally, the names of the resources are turned into constant field names that are checked at compile time, so there's less of an opportunity for mismatches between the code and the resources themselves. None of that applies to assets.

So why have an assets folder at all? If you want to compute the asset you want to use at run time, it's pretty easy. With resources, you would have to declare a list of all the resource IDs that might be used and compute an index into the the list. (This is kind of awkward and introduces opportunities for error if the set of resources changes in the development cycle.) (EDIT: you can retrieve a resource ID by name using getIdentifier, but this loses the benefits of compile-time checking.) Assets can also be organized into a folder hierarchy, which is not supported by resources. It's a different way of managing data. Although resources cover most of the cases, assets have their occasional use.

One other difference: resources defined in a library project are automatically imported to application projects that depend on the library. For assets, that doesn't happen; asset files must be present in the assets directory of the application project(s). [EDIT: With Android's new Gradle-based build system (used with Android Studio), this is no longer true. Asset directories for library projects are packaged into the .aar files, so assets defined in library projects are merged into application projects (so they do not have to be present in the application's /assets directory if they are in a referenced library).]

EDIT: Yet another difference arises if you want to package a custom font with your app. There are API calls to create a Typeface from a font file stored in the file system or in your app's assets/ directory. But there is no API to create a Typeface from a font file stored in the res/ directory (or from an InputStream, which would allow use of the res/ directory). [NOTE: With Android O (now available in alpha preview) you will be able to include custom fonts as resources. See the description here of this long-overdue feature. However, as long as your minimum API level is 25 or less, you'll have to stick with packaging custom fonts as assets rather than as resources.]

You dont have a function named assign(), but a method with this name. PHP is not Java and in PHP you have to make clear, if you want to call a function

assign()

or a method

$object->assign()

In your case the call to the function resides inside another method. $this always refers to the object, in which a method exists, itself.

$this->assign()

After a fight with this issue, I finally end up with this workaround:

/**
 * Dismiss {@link ProgressDialog} with check for nullability and SDK version
 *
 * @param dialog instance of {@link ProgressDialog} to dismiss
 */
public void dismissProgressDialog(ProgressDialog dialog) {
    if (dialog != null && dialog.isShowing()) {

            //get the Context object that was used to great the dialog
            Context context = ((ContextWrapper) dialog.getContext()).getBaseContext();

            // if the Context used here was an activity AND it hasn't been finished or destroyed
            // then dismiss it
            if (context instanceof Activity) {

                // Api >=17
                if (!((Activity) context).isFinishing() {
                    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
                        if (!((Activity) context).isDestroyed()) {
                            dismissWithExceptionHandling(dialog);
                        }
                    } else { 
                        // Api < 17. Unfortunately cannot check for isDestroyed()
                        dismissWithExceptionHandling(dialog);
                    }
                }
            } else
                // if the Context used wasn't an Activity, then dismiss it too
                dismissWithExceptionHandling(dialog);
        }
        dialog = null;
    }
}

/**
 * Dismiss {@link ProgressDialog} with try catch
 *
 * @param dialog instance of {@link ProgressDialog} to dismiss
 */
public void dismissWithExceptionHandling(ProgressDialog dialog) {
    try {
        dialog.dismiss();
    } catch (final IllegalArgumentException e) {
        // Do nothing.
    } catch (final Exception e) {
        // Do nothing.
    } finally {
        dialog = null;
    }
}

Sometimes, good exception handling works well if there wasn't a better solution for this issue.

You're removing and then incrementing, which means you'll be one ahead of yourself. Instead, remove in reverse so you never mess up your next item.

for (int i = ChunkList.Count-1; i >=0; i--)
{
    if (ChunkList[i].UniqueID == ChunkID)
    {
        ChunkList.RemoveAt(i);
    }
}

To somewhat expand on earlier answers, there are a few complications.

telnet is not particularly scriptable; you might prefer to use nc (aka netcat) instead, which handles non-terminal input and signals better.

Also, unlike telnet, nc actually allows SSL (and so https instead of http traffic -- you need port 443 instead of port 80 then).

There is a difference between HTTP 1.0 and 1.1. The recent version of the protocol requires the Host: header to be included in the request on a separate line after the POST or GET line, and to be followed by an empty line to mark the end of the request headers.

The HTTP protocol requires carriage return / line feed line endings. Many servers are lenient about this, but some are not. You might want to use

printf "%\r\n" \
    "GET /questions HTTP/1.1" \
    "Host: stackoverflow.com" \
    "" |
nc --ssl stackoverflow.com 443

If you fall back to HTTP/1.0 you don't always need the Host: header, but many modern servers require the header anyway; if multiple sites are hosted on the same IP address, the server doesn't know from GET /foo HTTP/1.0 whether you mean http://site1.example.com/foo or http://site2.example.net/foo if those two sites are both hosted on the same server (in the absence of a Host: header, a HTTP 1.0 server might just default to a different site than the one you want, so you don't get the contents you wanted).

The HTTPS protocol is identical to HTTP in these details; the only real difference is in how the session is set up initially.

You must use a .ts file - e.g. test.ts to get Typescript validation, intellisense typing of vars, return types, as well as "typed" error checking (e.g. passing a string to a method that expects an number param will error out).

It will be transpiled into (standard) .js via tsc.

Update (11/2018):

Clarification needed based on down-votes, very helpful comments and other answers.

types

• Yes, you can do type checking in VS Code in .js files with @ts-check - as shown in the animation

• What I originally was referring to for Typescript types is something like this in .ts which isn't quite the same thing:

  hello-world.ts

  function hello(str: string): string {
    return 1;
  }
  
  function foo(str:string):void{
     console.log(str);
  }
  

  This will not compile. Error: Type "1" is not assignable to String

• if you tried this syntax in a Javascript hello-world.js file:

  //@ts-check
  
  function hello(str: string): string {
    return 1;
  }
  
  function foo(str:string):void{
     console.log(str);
  }
  

  The error message referenced by OP is shown: [js] 'types' can only be used in a .ts file

If there's something I missed that covers this as well as the OP's context, please add. Let's all learn.

You can also get DateTime object from timestamp, including your current daylight saving time:

public DateTime getDateTimeFromTimestamp(Long value) {
    TimeZone timeZone = TimeZone.getDefault();
    long offset = timeZone.getOffset(value);
    if (offset < 0) {
        value -= offset;
    } else {
        value += offset;
    }
    return new DateTime(value);
}    

The best way I can think of to accomplish this is via sp_addlinkedserver. You need to make sure that whatever account you use to add the link (via sp_addlinkedsrvlogin) has permissions to the table you're joining, but then once the link is established, you can call the server by name, i.e.:

SELECT *
FROM server1table
    INNER JOIN server2.database.dbo.server2table ON .....

Unless performance is of utmost concern, it's often easier just to run your results through a second pass, skipping those that match the words you want to negate.

Regular expressions usually mean you're doing scripting or some sort of low-performance task anyway, so find a solution that is easy to read, easy to understand and easy to maintain.

An alternative way can be the following:

$this->expectException(\InvalidArgumentException::class);
$this->expectExceptionMessage('Expected Exception Message');

Thanks Yannis, your solution worked for me and here I'm sharing same solution for multiple keywords with order and limit.

instanceof works on instances, i.e. on Objects. Sometimes you want to work directly with classes. In this case you can use the asSubClass method of the Class class. Some examples:

1)

    Class o=Object.class;
    Class c=Class.forName("javax.swing.JFrame").asSubclass(o);

this will go through smoothly because JFrame is subclass of Object. c will contain a Class object representing the JFrame class.

2)

    Class o=JButton.class;
    Class c=Class.forName("javax.swing.JFrame").asSubclass(o);

this will launch a java.lang.ClassCastException because JFrame is NOT subclass of JButton. c will not be initialized.

3)

    Class o=Serializable.class;
    Class c=Class.forName("javax.swing.JFrame").asSubclass(o);

this will go through smoothly because JFrame implements the java.io.Serializable interface. c will contain a Class object representing the JFrame class.

Of course the needed imports have to be included.

try something like this

 URL u = new URL("http://www.puzzlers.org/pub/wordlists/pocket.txt");
 InputStream in = u.openStream();

Then use it as any plain old input stream

userAgent can be changed. for more robust, use the global variable specified by chrome

$.browser.chrome = (typeof window.chrome === "object");

Pass the items of the dictionary to the DataFrame constructor, and give the column names. After that parse the Date column to get Timestamp values.

Note the difference between python 2.x and 3.x:

In python 2.x:

df = pd.DataFrame(data.items(), columns=['Date', 'DateValue'])
df['Date'] = pd.to_datetime(df['Date'])

In Python 3.x: (requiring an additional 'list')

df = pd.DataFrame(list(data.items()), columns=['Date', 'DateValue'])
df['Date'] = pd.to_datetime(df['Date'])

Use Like below

<input type="file" accept=".xlsx,.xls,image/*,.doc, .docx,.ppt, .pptx,.txt,.pdf" />

I was looking long and hard for a solution to this problem and the best I found was a root FTP server on the phone that you connect to on Windows with an FTP client like FileZilla, on the same WiFi network of course.

The root FTP server app I ended up using is FTP Droid. I tried a lot of other FTP apps with bigger download numbers but none of them worked for me for whatever reason. So install this app and set a user with home as / or wherever you want.

Then make note of the phone IP and connect with FileZilla and you should have access to the root of the phone. The biggest benefit I found is I can download entire folders and FTP will just queue it up and take care of it. So I downloaded all of my /data/data/ folder when I was looking for an app and could search on my PC. Very handy.

You can use Object.defineProperty on the document object for the referrer property:

Object.defineProperty(document, "referrer", {get : function(){ return "my new referrer"; }});

Unfortunately this will not work on any version of safari <=5, Firefox < 4, Chrome < 5 and Internet Explorer < 9 as it doesn't allow defineProperty to be used on dom objects.

Oh! just read comments in question, dear I missed it. but just letting the answer be here in case it can be useful to some other person

I tried "Ctrl+C" and "Ctrl+ Break" none worked. I was using SQL Plus that came with Oracle Client 10.2.0.1.0. SQL Plus is used by most as client for connecting with Oracle DB. I used the Cancel, option under File menu and it stopped the execution!

Once you click File wait for few mins then the select command halts and menu appears click on Cancel.

This is a great plugin for use with update panels:

Sometimes it may occur, if there is any database connection in your code but you did not start the database server yet.

Im my case i have some piece of code to connect with mongodb

mongoose.connect("mongodb://localhost:27017/demoDb");

after i started the mongodb server with the command mongod this error is gone

Use:

.content {
    background: url('http://www.gransebryan.com/wp-content/uploads/2016/03/bryan-ganzon-granse-who.png') center no-repeat;
 }

.displaybg {
   text-align: center;
   color: #FFF;
}

Native way to get the mimetype:

For PHP < 5.3 use mime_content_type()
For PHP >= 5.3 use finfo_open() or mime_content_type()

Alternatives to get the MimeType are exif_imagetype and getimagesize, but these rely on having the appropriate libs installed. In addition, they will likely just return image mimetypes, instead of the whole list given in magic.mime.

While mime_content_type is available from PHP 4.3 and is part of the FileInfo extension (which is enabled by default since PHP 5.3, except for Windows platforms, where it must be enabled manually, for details see here).

If you don't want to bother about what is available on your system, just wrap all four functions into a proxy method that delegates the function call to whatever is available, e.g.

function getMimeType($filename)
{
    $mimetype = false;
    if(function_exists('finfo_open')) {
        // open with FileInfo
    } elseif(function_exists('getimagesize')) {
        // open with GD
    } elseif(function_exists('exif_imagetype')) {
       // open with EXIF
    } elseif(function_exists('mime_content_type')) {
       $mimetype = mime_content_type($filename);
    }
    return $mimetype;
}

$ne

selects the documents where the value of the field is not equal to the specified value. This includes documents that do not contain the field.

User.find({ "username": { "$ne": 'admin' } })

$nin

$nin selects the documents where: the field value is not in the specified array or the field does not exist.

User.find({ "groups": { "$nin": ['admin', 'user'] } })

You can do this by using asynchronous Javascript SDK provided by facebook

Have a look at the following code

FB Javascript SDK initialization

<div id="fb-root"></div>
<script>
window.fbAsyncInit = function() {
FB.init({appId: 'YOUR APP ID', status: true, cookie: true,
xfbml: true});
};
(function() {
var e = document.createElement('script'); e.async = true;
e.src = document.location.protocol +
'//connect.facebook.net/en_US/all.js';
document.getElementById('fb-root').appendChild(e);
}());
</script>

Note: Remember to replace YOUR APP ID with your facebook AppId. If you don't have facebook AppId and you don't know how to create please check this

Add JQuery Library, I would preferred Google Library

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.6.1/jquery.min.js" type="text/javascript"></script>

Add share dialog box (You can customize this dialog box by setting up parameters

<script type="text/javascript">
$(document).ready(function(){
$('#share_button').click(function(e){
e.preventDefault();
FB.ui(
{
method: 'feed',
name: 'This is the content of the "name" field.',
link: 'http://www.groupstudy.in/articlePost.php?id=A_111213073144',
picture: 'http://www.groupstudy.in/img/logo3.jpeg',
caption: 'Top 3 reasons why you should care about your finance',
description: "What happens when you don't take care of your finances? Just look at our country -- you spend irresponsibly, get in debt up to your eyeballs, and stress about how you're going to make ends meet. The difference is that you don't have a glut of taxpayers…",
message: ""
});
});
});
</script>

Now finally add image button

<img src = "share_button.png" id = "share_button">

• The zip function is useful here, used with a list comprehension v1, v2.
• If you have a list of lists (instead of just two lists) you can use v3.
• For lists with different length (for example: By adding 1 to the end of the first/secound list), then you can try something like this (using zip_longest) - v4

first = [1, 2, 3, 1]
second = [4, 5, 6]

output: [5, 7, 9, 1]

• If you have an unknown number of lists of the same length, you can use the function v5.

• v6 - The operator module exports a set of efficient functions corresponding to the intrinsic operators of Python. For example, operator.add(x, y) is equivalent to the expression x+y.

• v7 - Assuming both lists first and second have same length, you do not need zip or anything else.

For funsies... just collect the extensions in a dict, and track all of them in a folder. Then just pull the extensions you want.

import os

search = {}

for f in os.listdir(os.getcwd()):
    fn, fe = os.path.splitext(f)
    try:
        search[fe].append(f)
    except:
        search[fe]=[f,]

extensions = ('.png','.jpg')
for ex in extensions:
    found = search.get(ex,'')
    if found:
        print(found)

Assuming that btn refers to a UIButton, to change a multi-line caption to be centered horizontally, you can use the following statement in iOS 6 or later:

self.btn.titleLabel.textAlignment = NSTextAlignmentCenter;

You can use this command:

document.getElementById('iframeid').contentWindow.print();

This command basically is the same as window.print(), but as the window we would like to print is in the iframe, we first need to obtain an instance of that window as a javascript object.

So, in reference to that iframe, we first obtain the iframe by using it's id, and then it's contentWindow returns a window(DOM) object. So, we are able to directly use the window.print() function on this object.

If you want the sum of all bars to be equal unity, weight each bin by the total number of values:

weights = np.ones_like(myarray) / len(myarray)
plt.hist(myarray, weights=weights)

Hope that helps, although the thread is quite old...

Note for Python 2.x: add casting to float() for one of the operators of the division as otherwise you would end up with zeros due to integer division

There is no .net native method for shutting off the computer. You need to P/Invoke the ExitWindows or ExitWindowsEx API call.

If you are in same WORKGROUP shutdown.exe /s /m \\<target-computer-name> should be enough shutdown /? for more, otherwise you need software to connect and control the target server.

UPDATE:

Seems shutdown.bat here is for shutting down apache-tomcat.

So, you might be interested to psexec or PuTTY: A Free Telnet/SSH Client

As native solution could be wmic

Example:

wmic /node:<target-computer-name> process call create "cmd.exe c:\\somefolder\\batch.bat"

In your example should be:

wmic /node:inidsoasrv01 process call create ^
    "cmd.exe D:\\apache-tomcat-6.0.20\\apache-tomcat-7.0.30\\bin\\shutdown.bat"

wmic /? and wmic /node /? for more

You can Try this ,

Here you can get the date based on the Client Timezone (Browser).

moment(new Date().getTime()).zone(new Date().toString().match(/([-\+][0-9]+)\s/)[1]).format('YYYY-MM-DD HH:mm:ss')

The regex basically gets you the offset value.

It sounds like your ~/.ssh/authorized_keys file is not set up correctly. Verify that:

• It is in the correct path.
• The permissions of the file are 0600.
• The permissions of ~/.ssh are 0700.

The PropertiesPlaceholderConfigurer bean has an alternative property called "propertiesArray". Use this instead of the "properties" property, and configure it with an <array> of property references.

worked for me

in this case the original question (yourMigrationName = CategoryIdIsLong)

I simply went to the XAMMP config button in the XAMPP control panel GUI and clicked on Server and Port settings and I changed the SSL port value.

Use PushState and Precomposition

The current (2015) way to do this is using the JavaScript pushState method.

PushState changes the URL in the top browser bar without reloading the page. Say you have a page containing tabs. The tabs hide and show content, and the content is inserted dynamically, either using AJAX or by simply setting display:none and display:block to hide and show the correct tab content.

When the tabs are clicked, use pushState to update the url in the address bar. When the page is rendered, use the value in the address bar to determine which tab to show. Angular routing will do this for you automatically.

Precomposition

There are two ways to hit a PushState Single Page App (SPA)

1. Via PushState, where the user clicks a PushState link and the content is AJAXed in.
2. By hitting the URL directly.

The initial hit on the site will involve hitting the URL directly. Subsequent hits will simply AJAX in content as the PushState updates the URL.

Crawlers harvest links from a page then add them to a queue for later processing. This means that for a crawler, every hit on the server is a direct hit, they don't navigate via Pushstate.

Precomposition bundles the initial payload into the first response from the server, possibly as a JSON object. This allows the Search Engine to render the page without executing the AJAX call.

There is some evidence to suggest that Google might not execute AJAX requests. More on this here:

https://web.archive.org/web/20160318211223/http://www.analog-ni.co/precomposing-a-spa-may-become-the-holy-grail-to-seo

Search Engines can read and execute JavaScript

Google has been able to parse JavaScript for some time now, it's why they originally developed Chrome, to act as a full featured headless browser for the Google spider. If a link has a valid href attribute, the new URL can be indexed. There's nothing more to do.

If clicking a link in addition triggers a pushState call, the site can be navigated by the user via PushState.

Search Engine Support for PushState URLs

PushState is currently supported by Google and Bing.

Google

Here's Matt Cutts responding to Paul Irish's question about PushState for SEO:

http://youtu.be/yiAF9VdvRPw

Here is Google announcing full JavaScript support for the spider:

http://googlewebmastercentral.blogspot.de/2014/05/understanding-web-pages-better.html

The upshot is that Google supports PushState and will index PushState URLs.

See also Google webmaster tools' fetch as Googlebot. You will see your JavaScript (including Angular) is executed.

Bing

Here is Bing's announcement of support for pretty PushState URLs dated March 2013:

http://blogs.bing.com/webmaster/2013/03/21/search-engine-optimization-best-practices-for-ajax-urls/

Don't use HashBangs #!

Hashbang urls were an ugly stopgap requiring the developer to provide a pre-rendered version of the site at a special location. They still work, but you don't need to use them.

Hashbang URLs look like this:

domain.com/#!path/to/resource

This would be paired with a metatag like this:

<meta name="fragment" content="!">

Google will not index them in this form, but will instead pull a static version of the site from the _escaped_fragments_ URL and index that.

Pushstate URLs look like any ordinary URL:

domain.com/path/to/resource

The difference is that Angular handles them for you by intercepting the change to document.location dealing with it in JavaScript.

If you want to use PushState URLs (and you probably do) take out all the old hash style URLs and metatags and simply enable HTML5 mode in your config block.

Testing your site

Google Webmaster tools now contains a tool which will allow you to fetch a URL as google, and render JavaScript as Google renders it.

https://www.google.com/webmasters/tools/googlebot-fetch

Generating PushState URLs in Angular

To generate real URLs in Angular, rather than # prefixed ones, set HTML5 mode on your $locationProvider object.

$locationProvider.html5Mode(true);

Server Side

Since you are using real URLs, you will need to ensure the same template (plus some precomposed content) gets shipped by your server for all valid URLs. How you do this will vary depending on your server architecture.

Sitemap

Your app may use unusual forms of navigation, for example hover or scroll. To ensure Google is able to drive your app, I would probably suggest creating a sitemap, a simple list of all the urls your app responds to. You can place this at the default location (/sitemap or /sitemap.xml), or tell Google about it using webmaster tools.

It's a good idea to have a sitemap anyway.

Browser support

Pushstate works in IE10. In older browsers, Angular will automatically fall back to hash style URLs

A demo page

The following content is rendered using a pushstate URL with precomposition:

http://html5.gingerhost.com/london

As can be verified, at this link, the content is indexed and is appearing in Google.

Serving 404 and 301 Header status codes

Because the search engine will always hit your server for every request, you can serve header status codes from your server and expect Google to see them.

Implement the UITextFieldDelegate method like this:

- (BOOL)textFieldShouldReturn:(UITextField *)aTextField
{
    [aTextField resignFirstResponder];
    return YES;
}

OK, the answer is easy... You basically see the branch, but you don't have a local copy yet!...

You need to fetch the branch...

You can simply fetch and then checkout to the branch, use the one line command below to do that:

git fetch && git checkout test

I also created the image below for you to share the differences, look at how fetch works and also how it's different to pull:

This worked for me fine:

File 1:

    <html>
    <head></head>
    <body>
        <a href="#" onclick="window.open('file:///D:/Examples/file2.html'); return false">CLICK ME</a>
    </body>
    <footer></footer>
    </html>

File 2:

    <html>
        ...
    </html>

This method works regardless of whether or not the 2 files are in the same directory, BUT both files must be local.

For obvious security reasons, if File 1 is located on a remote server you absolutely cannot open a file on some client's host computer and trying to do so will open a blank target.

Useful in scripts:

Get only the STDERR in a file, while hiding any STDOUT even if the program to hide isn't existing at all (does not ever hang parent script), this alone was working:

stty -echo && ./programMightNotExist 2> errors.log && stty echo

Detach completely and silence everything, even killing the parent script won't abort ./prog :

 ./prog </dev/null >/dev/null 2>&1 &

I had the same problem with SQLite and Android. Here is my Solution:

List<String> tables = new ArrayList<String>();
Cursor cursor = db.rawQuery("SELECT * FROM sqlite_master WHERE type='table';", null);
cursor.moveToFirst();
while (!cursor.isAfterLast()) {
    String tableName = cursor.getString(1);
    if (!tableName.equals("android_metadata") &&
            !tableName.equals("sqlite_sequence"))
        tables.add(tableName);
    cursor.moveToNext();
}
cursor.close();

for(String tableName:tables) {
    db.execSQL("DROP TABLE IF EXISTS " + tableName);
}

On Ubuntu, this can also be caused by incorrect permissions. I chmod 755 Logs/ which fixed the issue.

Use java.util.concurrent.TimeUnit:

TimeUnit.SECONDS.sleep(1);

Sleep for one second or

TimeUnit.MINUTES.sleep(1);

Sleep for a minute.

As this is a loop, this presents an inherent problem - drift. Every time you run code and then sleep you will be drifting a little bit from running, say, every second. If this is an issue then don't use sleep.

Further, sleep isn't very flexible when it comes to control.

For running a task every second or at a one second delay I would strongly recommend a [ScheduledExecutorService][1] and either [scheduleAtFixedRate][2] or [scheduleWithFixedDelay][3].

To run the method myTask every second (Java 8):

public static void main(String[] args) {
    final ScheduledExecutorService executorService = Executors.newSingleThreadScheduledExecutor();
    executorService.scheduleAtFixedRate(App::myTask, 0, 1, TimeUnit.SECONDS);
}

private static void myTask() {
    System.out.println("Running");
}

As an alternate to adding a comma for each item you could just using String.Join:

var strgroupids = String.Join(",",  groupIds);

This will add the seperator ("," in this instance) between each element in the array.

As mentioned by ecdpalma below, git 1.7.12+ (August 2012) has enhanced the option --root for git rebase:

"git rebase [-i] --root $tip" can now be used to rewrite all the history leading to "$tip" down to the root commit.

That new behavior was initially discussed here:

I personally think "git rebase -i --root" should be made to just work without requiring "--onto" and let you "edit" even the first one in the history.
It is understandable that nobody bothered, as people are a lot less often rewriting near the very beginning of the history than otherwise.

The patch followed.

(original answer, February 2010)

As mentioned in the Git FAQ (and this SO question), the idea is:

1. Create new temporary branch
2. Rewind it to the commit you want to change using git reset --hard
3. Change that commit (it would be top of current HEAD, and you can modify the content of any file)

4. Rebase branch on top of changed commit, using:

   git rebase --onto <tmp branch> <commit after changed> <branch>`
   

The trick is to be sure the information you want to remove is not reintroduced by a later commit somewhere else in your file. If you suspect that, then you have to use filter-branch --tree-filter to make sure the content of that file does not contain in any commit the sensible information.

In both cases, you end up rewriting the SHA1 of every commit, so be careful if you have already published the branch you are modifying the contents of. You probably shouldn’t do it unless your project isn’t yet public and other people haven’t based work off the commits you’re about to rewrite.

use print_r(Auth);

then see in which format you have user_id / id variable and use it

For HeidiSQL users:

If you use HeidiSQL, you can select the row(s) you wish to get insert statement. Then right click > Export grid rows > select "Copy to clipboard" for "Output target", "Selection" for "Row Selection" so you don't export other rows, "SQL INSERTs" for "Output format" > Click OK.

The insert statement will be inside you clipboard.

bool b = list.Contains("Hello", StringComparer.CurrentCultureIgnoreCase);

[EDIT] extension code:

public static bool Contains(this string source, string cont
                                                    , StringComparison compare)
{
    return source.IndexOf(cont, compare) >= 0;
}

This could work :)

DECLARE @StartDate DATE = '2017-09-13',         @EndDate DATE = '2017-09-16'

SELECT date  FROM (   SELECT DATE = DATEADD(DAY, rn - 1, @StartDate)   FROM    (
    SELECT TOP (DATEDIFF(DAY, @StartDate, DATEADD(DAY,1,@EndDate)))
      rn = ROW_NUMBER() OVER (ORDER BY s1.[object_id])
    FROM sys.all_objects AS s1
    CROSS JOIN sys.all_objects AS s2
    ORDER BY s1.[object_id]   ) AS x ) AS y

Result:

2017-09-13

2017-09-14

2017-09-15

Here's a blog post describing the creation of an IsInteger UDF.

Basically, it recommends adding '.e0' to the value and using IsNumeric. In this way, anything that already had a decimal point now has two decimal points, causing IsNumeric to be false, and anything already expressed in scientific notation is invalidated by the e0.

Adding my heavily upvoted comment as an answer with screenshots.

I spent a lot of time on this, finally what worked for me is:

1) Open Sql Server Configuration Manager --> SQL Server Network configuration --> Protocols for <(INSTANCE)> --> TCP/IP (double click on it).

2) Select --> IP Addresses(Tab).

3) Go to the last entry IP All and mention TCP Port 1433.

4) Press Win+R and enter services.msc.

5) Now restart SQL Server <(INSTANCE)>.

After this, the problem got resolved!

It's possible that the Windows internal resolver is adding '.local' to the domain name because there's no dots in it. nslookup wouldn't do that.

To verify this possiblity, install 'Wireshark' (previously aka Ethereal) on your client machine and observe any DNS request packets leaving it when you run the ping command.

OK, further investigation on my own XP machine at home reveals that for single label names (i.e. "foo", or "foo.") the system doesn't use DNS at all, and instead uses NBNS (NetBios Name Service).

Using a hint found at http://www.chicagotech.net/netforums/viewtopic.php?t=1476, I found that I was able to force DNS lookups for single label domains by putting a single entry reading "." in the "Append these DNS suffixes (in order)" in the "Advanced TCP/IP settings" dialog

Use something like this (Not compiler checked)

NSMutableAttributedString *string = [[NSMutableAttributedString alloc]initWithString:self.text.text];
NSRange range=[self.myLabel.text rangeOfString:texts[sliderValue]]; //myLabel is the outlet from where you will get the text, it can be same or different

NSArray *colors=@[[UIColor redColor],
                  [UIColor redColor],
                  [UIColor yellowColor],
                  [UIColor greenColor]
                 ];

[string addAttribute:NSForegroundColorAttributeName 
               value:colors[sliderValue] 
               range:range];           

[self.scanLabel setAttributedText:texts[sliderValue]];

That's the correct usage, but perhaps the spaces in the path name are messing things up for some reason.

You may want to run the program under cmd.exe as well so you can see any output from flow.exe that might be indicating an error.

In short you have to do like this

repositories {
  maven { url "http://maven.springframework.org/release" }
  maven { url "https://maven.fabric.io/public" }
}

Detail:

You need to specify each maven URL in its own curly braces. Here is what I got working with skeleton dependencies for the web services project I’m going to build up:

apply plugin: 'java'

sourceCompatibility = 1.7
version = '1.0'

repositories {
  maven { url "http://maven.springframework.org/release" }
  maven { url "http://maven.restlet.org" }
  mavenCentral()
}

dependencies {
  compile group:'org.restlet.jee', name:'org.restlet', version:'2.1.1'
  compile group:'org.restlet.jee', name:'org.restlet.ext.servlet',version.1.1'
  compile group:'org.springframework', name:'spring-web', version:'3.2.1.RELEASE'
  compile group:'org.slf4j', name:'slf4j-api', version:'1.7.2'
  compile group:'ch.qos.logback', name:'logback-core', version:'1.0.9'
  testCompile group:'junit', name:'junit', version:'4.11'
}

Blog

Here's two options. I prefer the navigationAlt option since it involves less work in the end:

<html>_x000D_
_x000D_
<head>_x000D_
  <style type="text/css">_x000D_

A hint for anyone experiencing this. This can happen when a switchMap doesn't receive an observable return value (like null). Simply add a default case, so it always returns an observable.

        switchMap((dateRange) => {
          if (dateRange === 'Last 24 hours') {
            return $observable1;
          }
          if (dateRange === 'Last 7 Days') {
            return $observable2;
          }
          if (dateRange === 'Last 30 Days') {
            return $observable3;
          }
          // This line will work for default cases
          return $observableElse;
        })

This might help someone like me that finds this answer when searching for solutions to how Rails handles the class loading ... I found that I had to define a module whose name matched my filename appropriately, rather than just defining a class:

In file lib/development_mail_interceptor.rb (Yes, I'm using code from a Railscast :))

module DevelopmentMailInterceptor
  class DevelopmentMailInterceptor
    def self.delivering_email(message)
      message.subject = "intercepted for: #{message.to} #{message.subject}"
      message.to = "[email protected]"
    end
  end
end

works, but it doesn't load if I hadn't put the class inside a module.

The expression:

 ($min <= $value) && ($value <= $max)

will be true if $value is between $min and $max, inclusively

See the PHP docs for more on comparison operators

Use set_index with stack for MultiIndex Series, then for DataFrame add reset_index with rename:

df1 = (df.set_index(["location", "name"])
         .stack()
         .reset_index(name='Value')
         .rename(columns={'level_2':'Date'}))
print (df1)
  location  name        Date  Value
0        A  test    Jan-2010     12
1        A  test    Feb-2010     20
2        A  test  March-2010     30
3        B   foo    Jan-2010     18
4        B   foo    Feb-2010     20
5        B   foo  March-2010     25

Use the -ExpandProperty flag of Select-Object

$var=Get-WSManInstance -enumerate wmicimv2/win32_process | select -expand Priority

Update to answer the other question:

Note that you can as well just access the property:

$var=(Get-WSManInstance -enumerate wmicimv2/win32_process).Priority

So to get multiple of these into variables:

$var=Get-WSManInstance -enumerate wmicimv2/win32_process
   $prio = $var.Priority
   $pid = $var.ProcessID

git checkout foo/bar.txt

did you tried that? (without a HEAD keyword)

I usually revert my changes this way.

Set up HADOOP_HOME variable in windows to resolve the problem.

You can find answer in org/apache/hadoop/hadoop-common/2.2.0/hadoop-common-2.2.0-sources.jar!/org/apache/hadoop/util/Shell.java :

IOException from

  public static final String getQualifiedBinPath(String executable) 
  throws IOException {
    // construct hadoop bin path to the specified executable
    String fullExeName = HADOOP_HOME_DIR + File.separator + "bin" 
      + File.separator + executable;
    File exeFile = new File(fullExeName);
    if (!exeFile.exists()) {
      throw new IOException("Could not locate executable " + fullExeName
        + " in the Hadoop binaries.");
    }
    return exeFile.getCanonicalPath();
  }

HADOOP_HOME_DIR from

// first check the Dflag hadoop.home.dir with JVM scope
String home = System.getProperty("hadoop.home.dir");
// fall back to the system/user-global env variable
if (home == null) {
  home = System.getenv("HADOOP_HOME");
}

The canonic answer, in Python, would be :

s = ''.join(s.splitlines())

It splits the string into lines (letting Python doing it according to its own best practices). Then you merge it. Two possibilities here:

• replace the newline by a whitespace (' '.join())
• or without a whitespace (''.join())

For SQL Server, if using a newer version, you can use

select *
from INFORMATION_SCHEMA.COLUMNS
where TABLE_NAME='tableName'

There are different ways to get the schema. Using ADO.NET, you can use the schema methods. Use the DbConnection's GetSchema method or the DataReader'sGetSchemaTable method.

Provided that you have a reader for the for the query, you can do something like this:

using(DbCommand cmd = ...)
using(var reader = cmd.ExecuteReader())
{
    var schema = reader.GetSchemaTable();
    foreach(DataRow row in schema.Rows)
    {
        Debug.WriteLine(row["ColumnName"] + " - " + row["DataTypeName"])
    }
}

This is the best solution ever rather than hacking CSS.

I've created a simple library for handling optional arguments with JavaScript functions, see https://github.com/ovatto/argShim. The library is developed with Node.js in mind but should be easily ported to work with e.g. browsers.

Example:

var argShim = require('argShim');
var defaultOptions = {
  myOption: 123
};

var my_function = argShim([
    {optional:'String'},
    {optional:'Object',default:defaultOptions}
  ], function(content, options) {
    console.log("content:", content, "options:", options);
  });

my_function();
my_function('str');
my_function({myOption:42});
my_function('str', {myOption:42});

Output:

content: undefined options: { myOption: 123 }
content: str options: { myOption: 123 }
content: undefined options: { myOption: 42 }
content: str options: { myOption: 42 }

The main target for the library are module interfaces where you need to be able to handle different invocations of exported module functions.

Charles is written in Java and runs on Macs. It's not free though.

You can point your Mac at your Windows+Fiddler machine: http://www.fiddler2.com/fiddler/help/hookup.asp#Q-NonWindows

And as of 2013, there's an Alpha download of Fiddler for the Mono Framework, which runs on Mac and Linux. Also, the very latest version of Fiddler can import .PCAP files captured from WireShark or other tools run on the Mac.

For use key/value pair in json use an object and don't use array

Find name/value in array is hard but in object is easy

Ex:

var exObj = {_x000D_
  "mainData": {_x000D_
    "slide0001.html": "Looking Ahead",_x000D_
    "slide0008.html": "Forecast",_x000D_
    "slide0021.html": "Summary",_x000D_
    // another THOUSANDS KEY VALUE PAIRS_x000D_
    // ..._x000D_
  },_x000D_
  "otherdata" : { "one": "1", "two": "2", "three": "3" }_x000D_
};_x000D_
var mainData = exObj.mainData;_x000D_
// for use:_x000D_
Object.keys(mainData).forEach(function(n,i){_x000D_
  var v = mainData[n];_x000D_
  console.log('name' + i + ': ' + n + ', value' + i + ': ' + v);_x000D_
});_x000D_
_x000D_
// and string length is minimum_x000D_
console.log(JSON.stringify(exObj));_x000D_
console.log(JSON.stringify(exObj).length);

Try:

$result = curl_exec($cURL);
$result = json_decode($result,true);

Now you can access MessageID from $result['MessageID'].

As for the database, it's simply using a query like so:

INSERT INTO `tableName`(`Cancelled`,`Queued`,`SMSError`,`SMSIncommingMessage`,`Sent`,`SentDateTime`) VALUES('?','?','?','?','?');

Prepared.

Replace

onclick="changeLink();"

You don't need to create an intermediate file. You can do

pg_dump -C -h localhost -U localuser dbname | psql -h remotehost -U remoteuser dbname

or

pg_dump -C -h remotehost -U remoteuser dbname | psql -h localhost -U localuser dbname

using psql or pg_dump to connect to a remote host.

With a big database or a slow connection, dumping a file and transfering the file compressed may be faster.

As Kornel said there is no need to dump to a intermediate file, if you want to work compressed you can use a compressed tunnel

pg_dump -C dbname | bzip2 | ssh  remoteuser@remotehost "bunzip2 | psql dbname"

or

pg_dump -C dbname | ssh -C remoteuser@remotehost "psql dbname"

but this solution also requires to get a session in both ends.

Note: pg_dump is for backing up and psql is for restoring. So, the first command in this answer is to copy from local to remote and the second one is from remote to local. More -> https://www.postgresql.org/docs/9.6/app-pgdump.html

Anyone who is just starting with Haskell and trying to print an Int, use:

I created a little javascript tool to style elements on screen size without using media queries or recompiling bootstrap css:

https://github.com/Heras/Responsive-Breakpoints

Just add class responsive-breakpoints to any element, and it will automagically add xs sm md lg xl classes to those elements.

from collections import Counter
from scipy import stats

labels = [0.9, 0.09, 0.1]
stats.entropy(list(Counter(labels).keys()), base=2)

Use the checked attribute.

<input type="radio" name="imgsel"  value="" checked /> 

or

<input type="radio" name="imgsel"  value="" checked="checked" /> 

This should do what you're looking for.

CSS:

html, body {

    margin: 0;

  height: 100%;
}

HTML:

<div class="gif-container"></div>

../ takes you one folder up the directory tree. Then, select the appropriate folder and its contents.

../images/logo.png

From what i understand, you don't wanna remove it, nor hide it ? Because you might wanna reuse it later ..but don't want it to have the old content if ever you open it up again ?

<div class="modal hide fade">
    <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times</button>
        <h3>Modal header</h3>
    </div>
    <div class="modal-body">
        <p>One fine body…</p>
    </div>
    <div class="modal-footer">
        <a href="#" class="btn">Close</a>
        <a href="#" class="btn btn-primary">Save changes</a>
    </div>
</div>

If you wanna use it as a dynamic template just do something like

$(selector).modal({show: true})

....

$(selector).modal({show: false})
$(".modal-body").empty()

....

$(".modal-body").append("new stuff & text")
$(selector).modal({show: true})

Tensorflow 2.1+

What's going on?

With the new Tensorflow 2.1 release, the default tensorflow pip package contains both CPU and GPU versions of TF. In previous TF versions, not finding the CUDA libraries would emit an error and raise an exception, while now the library dynamically searches for the correct CUDA version and, if it doesn't find it, emits the warning (The W in the beginning stands for warnings, errors have an E (or F for fatal errors) and falls back to CPU-only mode. In fact, this is also written in the log as an info message right after the warning (do note that if you have a higher minimum log level that the default, you might not see info messages). The full log is (emphasis mine):

2020-01-20 12:27:44.554767: W tensorflow/stream_executor/platform/default/dso_loader.cc:55] Could not load dynamic library 'cudart64_101.dll'; dlerror: cudart64_101.dll not found

2020-01-20 12:27:44.554964: I tensorflow/stream_executor/cuda/cudart_stub.cc:29] Ignore above cudart dlerror if you do not have a GPU set up on your machine.

Should I worry? How do I fix it?

If you don't have a CUDA-enabled GPU on your machine, or if you don't care about not having GPU acceleration, no need to worry. If, on the other hand, you installed tensorflow and wanted GPU acceleration, check your CUDA installation (TF 2.1 requires CUDA 10.1, not 10.2 or 10.0).

If you just want to get rid of the warning, you can adapt TF's logging level to suppress warnings, but that might be overkill, as it will silence all warnings.

Tensorflow 1.X or 2.0:

Your CUDA setup is broken, ensure you have the correct version installed.

Here is another method to get date

new Date().getDate()          // Get the day as a number (1-31)
new Date().getDay()           // Get the weekday as a number (0-6)
new Date().getFullYear()      // Get the four digit year (yyyy)
new Date().getHours()         // Get the hour (0-23)
new Date().getMilliseconds()  // Get the milliseconds (0-999)
new Date().getMinutes()       // Get the minutes (0-59)
new Date().getMonth()         // Get the month (0-11)
new Date().getSeconds()       // Get the seconds (0-59)
new Date().getTime()          // Get the time (milliseconds since January 1, 1970)

The pattern yyyy-MM-dd isn't an officially supported format for Date constructor. Firefox seems to support it, but don't count on other browsers doing the same.

Here are some supported strings:

• MM-dd-yyyy
• yyyy/MM/dd
• MM/dd/yyyy
• MMMM dd, yyyy
• MMM dd, yyyy

DateJS seems like a good library for parsing non standard date formats.

Edit: just checked ECMA-262 standard. Quoting from section 15.9.1.15:

Date Time String Format

ECMAScript defines a string interchange format for date-times based upon a simplification of the ISO 8601 Extended Format. The format is as follows: YYYY-MM-DDTHH:mm:ss.sssZ Where the fields are as follows:

• YYYY is the decimal digits of the year in the Gregorian calendar.
• "-" (hyphon) appears literally twice in the string.
• MM is the month of the year from 01 (January) to 12 (December).
• DD is the day of the month from 01 to 31.
• "T" appears literally in the string, to indicate the beginning of the time element.
• HH is the number of complete hours that have passed since midnight as two decimal digits.
• ":" (colon) appears literally twice in the string.
• mm is the number of complete minutes since the start of the hour as two decimal digits.
• ss is the number of complete seconds since the start of the minute as two decimal digits.
• "." (dot) appears literally in the string.
• sss is the number of complete milliseconds since the start of the second as three decimal digits. Both the "." and the milliseconds field may be omitted.
• Z is the time zone offset specified as "Z" (for UTC) or either "+" or "-" followed by a time expression hh:mm

This format includes date-only forms:

• YYYY
• YYYY-MM
• YYYY-MM-DD

It also includes time-only forms with an optional time zone offset appended:

• THH:mm
• THH:mm:ss
• THH:mm:ss.sss

Also included are "date-times" which may be any combination of the above.

So, it seems that YYYY-MM-DD is included in the standard, but for some reason, Safari doesn't support it.

Update: after looking at datejs documentation, using it, your problem should be solved using code like this:

var myDate1 = Date.parseExact("29-11-2010", "dd-MM-yyyy");
var myDate2 = Date.parseExact("11-29-2010", "MM-dd-yyyy");
var myDate3 = Date.parseExact("2010-11-29", "yyyy-MM-dd");
var myDate4 = Date.parseExact("2010-29-11", "yyyy-dd-MM");

You can remove the entire line below:

 .map((res: Response) => res.json());

No need to use the map method at all.

Create cmd file with line:

for %%p in (C D E F G H I J K L M N O P Q R S T U V W X Y Z) do if exist "%%p:\$Recycle.Bin" rundll32.exe advpack.dll,DelNodeRunDLL32 "%%p:\$Recycle.Bin"

The foreign keys in your schema (on Account_Name and Account_Type) do not require any special treatment or syntax. Just declare two separate foreign keys on the Customer table. They certainly don't constitute a composite key in any meaningful sense of the word.

There are numerous other problems with this schema, but I'll just point out that it isn't generally a good idea to build a primary key out of multiple unique columns, or columns in which one is functionally dependent on another. It appears that at least one of these cases applies to the ID and Name columns in the Customer table. This allows you to create two rows with the same ID (different name), which I'm guessing you don't want to allow.

You need to change

  <activity
        android:name=".YOUR ACTIVITY"
        android:theme="@style/AppTheme.NoActionBar" />
</application>`

these lines in the manifest.It will perfectly work for me.

If you just want to remove the first two characters and the last two, then you can use negative indexes on the string:

s = "((String1))"
s = s[2...-2]
p s # => "String1"

If you want to remove all parentheses from the string you can use the delete method on the string class:

s = "((String1))"
s.delete! '()'
p s #  => "String1"

There is no default command to do that, but you may create a procedure to do the job. It will iterate through rows of information_schema and call REPAIR TABLE 'tablename'; for every row. CHECK TABLE is not yet supported for prepared statements. Here's the example (replace MYDATABASE with your database name):

CREATE DEFINER = 'root'@'localhost'
PROCEDURE MYDATABASE.repair_all()
BEGIN
  DECLARE endloop INT DEFAULT 0;
  DECLARE tableName char(100);
  DECLARE rCursor CURSOR FOR SELECT `TABLE_NAME` FROM `information_schema`.`TABLES` WHERE `TABLE_SCHEMA`=DATABASE();
  DECLARE CONTINUE HANDLER FOR SQLSTATE '02000' SET endloop=1;

  OPEN rCursor;
  FETCH rCursor INTO tableName;

  WHILE endloop = 0 DO
    SET @sql = CONCAT("REPAIR TABLE `", tableName, "`");
    PREPARE statement FROM @sql;
    EXECUTE statement;

    FETCH rCursor INTO tableName;
  END WHILE;

  CLOSE rCursor;
END

Check your OpenCV version

import cv2
cv2.__version__

If your are running Python v3.x and OpenCV v4 and above:

pip install opencv-contrib-python

Try running your program again. This should now work.

Remove the Debug permissions on the Device, with the cell phone connected, then put them back, and ask if you want to allow the PC to have debug, accept and ready permissions: D

Following the idea posted by Andrew Seaford, this is done using sshfs:

echo "SuperHardToGuessPass:P" | sshfs -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no [email protected]:/mypath/ /mnt/source-tmp/ -o workaround=rename -o password_stdin
rsync -a /mnt/source-tmp/ /media/destination/
umount /mnt/source-tmp

Use ILSpy http://ilspy.net/

open source, free, definitely an option since now reflector is paid.

you can specify the max length for the multiline textbox in pageLoad Javascript Event

function pageLoad(){
                     $("[id$='txtInput']").attr("maxlength","10");
                    }

I have set the max length property of txtInput multiline textbox to 10 characters in pageLoad() Javascript function

Thanks for your replies. Here's what I did:

git gc
git gc --aggressive
git prune

That seemed to have done the trick. I started with around 10.5MB and now it's little more than 980KBs.

I had this issue start happening when debugging from one web project to a web service in the same solution. The web service was returning responses that the web project couldnt understand. It would kind of work again at some points, then stop again.

It was because there was not an explicit reference between these projects, so the web service was not getting built when hitting F5 to start debugging. Once I added that, the errors went away.

you can use the custom datetime by using...

 create table noteTable3 
 (created_at DATETIME DEFAULT (STRFTIME('%d-%m-%Y   %H:%M', 'NOW','localtime')),
 title text not null, myNotes text not null);

use 'NOW','localtime' to get the current system date else it will show some past or other time in your Database after insertion time in your db.

Thanks You...

It's the difference between strings and integers. See:

>>> "1" * 9
'111111111'

>>> 1 * 9
9

An alternative to the many solutions already provided is making use of the glob **. When you use bash with the option globstar (shopt -s globstar) or you make use of zsh, you can just use the glob ** for this.

**/bar

does a recursive directory search for files named bar (potentially including the file bar in the current directory). Remark that this cannot be combined with other forms of globbing within the same path segment; in that case, the * operators revert to their usual effect.

Note that there is a subtle difference between zsh and bash here. While bash will traverse soft-links to directories, zsh will not. For this you have to use the glob ***/ in zsh.

import re
pattern = re.compile("<(\d{4,5})>")

for i, line in enumerate(open('test.txt')):
    for match in re.finditer(pattern, line):
        print 'Found on line %s: %s' % (i+1, match.group())

A couple of notes about the regex:

• You don't need the ? at the end and the outer (...) if you don't want to match the number with the angle brackets, but only want the number itself
• It matches either 4 or 5 digits between the angle brackets

Update: It's important to understand that the match and capture in a regex can be quite different. The regex in my snippet above matches the pattern with angle brackets, but I ask to capture only the internal number, without the angle brackets.

More about regex in python can be found here : Regular Expression HOWTO

I found a pure Python 2 prime generator here , in a comment by Willy Good, that is faster than rwh2_primes.

def primes235(limit):
yield 2; yield 3; yield 5
if limit < 7: return
modPrms = [7,11,13,17,19,23,29,31]
gaps = [4,2,4,2,4,6,2,6,4,2,4,2,4,6,2,6] # 2 loops for overflow
ndxs = [0,0,0,0,1,1,2,2,2,2,3,3,4,4,4,4,5,5,5,5,5,5,6,6,7,7,7,7,7,7]
lmtbf = (limit + 23) // 30 * 8 - 1 # integral number of wheels rounded up
lmtsqrt = (int(limit ** 0.5) - 7)
lmtsqrt = lmtsqrt // 30 * 8 + ndxs[lmtsqrt % 30] # round down on the wheel
buf = [True] * (lmtbf + 1)
for i in xrange(lmtsqrt + 1):
    if buf[i]:
        ci = i & 7; p = 30 * (i >> 3) + modPrms[ci]
        s = p * p - 7; p8 = p << 3
        for j in range(8):
            c = s // 30 * 8 + ndxs[s % 30]
            buf[c::p8] = [False] * ((lmtbf - c) // p8 + 1)
            s += p * gaps[ci]; ci += 1
for i in xrange(lmtbf - 6 + (ndxs[(limit - 7) % 30])): # adjust for extras
    if buf[i]: yield (30 * (i >> 3) + modPrms[i & 7])

...on my recent midrange laptop (i5 8265U 1.6GHz) running Ubuntu on Win 10.

This is a mod 30 wheel sieve which skips multiples of 2, 3, and 5. It works great for me up to about 2.5e9, when my laptop starts running out of 8G RAM and swapping a lot.

I like mod 30 since it has only 8 remainders that aren't multiples of 2, 3, or 5. That enables using shifts and "&" for multiplication, division and mod, and should allow packing results for one mod 30 wheel into a byte. I have morphed Willy's code into a segmented mod 30 wheel sieve to eliminate the thrashing for big N and posted it here.

There is an even faster Javascript version which is segmented and uses a mod 210 wheel (no multiples of 2, 3, 5, or 7) by @GordonBGood with an in depth explanation that is useful to me.

Here using Hive warehouse dir you can export data instead of Hive table. first give hive warehouse path and after local path where you want to store the .csv file For this command is bellow :-

hadoop fs -cat /user/hdusr/warehouse/HiveDb/tableName/* > /users/hadoop/test/nilesh/sample.csv

Chrome DevTools, Safari Inspector and Firebug support getEventListeners(node).

You can rewrite how your onToggleLoop method is called from your render() method.

render() {
    var shuffleClassName = this.state.toggleActive ? "player-control-icon active" : "player-control-icon"

return (
  <div className="player-controls">
    <FontAwesome
      className="player-control-icon"
      name='refresh'
      onClick={(event) => this.onToggleLoop(event)}
      spin={this.state.loopActive}
    />       
  </div>
    );
  }

The React documentation shows this pattern in making calls to functions from expressions in attributes.

using padding pad

In order to move the colorbar relative to the subplot, one may use the pad argument to fig.colorbar.

import matplotlib.pyplot as plt
import numpy as np; np.random.seed(1)

fig, ax = plt.subplots(figsize=(4,4))
im = ax.imshow(np.random.rand(11,16))
ax.set_xlabel("x label")

fig.colorbar(im, orientation="horizontal", pad=0.2)
plt.show()

using an axes divider

One can use an instance of make_axes_locatable to divide the axes and create a new axes which is perfectly aligned to the image plot. Again, the pad argument would allow to set the space between the two axes.

import matplotlib.pyplot as plt
from mpl_toolkits.axes_grid1 import make_axes_locatable
import numpy as np; np.random.seed(1)

fig, ax = plt.subplots(figsize=(4,4))
im = ax.imshow(np.random.rand(11,16))
ax.set_xlabel("x label")

divider = make_axes_locatable(ax)
cax = divider.new_vertical(size="5%", pad=0.7, pack_start=True)
fig.add_axes(cax)
fig.colorbar(im, cax=cax, orientation="horizontal")

plt.show()

using subplots

One can directly create two rows of subplots, one for the image and one for the colorbar. Then, setting the height_ratios as gridspec_kw={"height_ratios":[1, 0.05]} in the figure creation, makes one of the subplots much smaller in height than the other and this small subplot can host the colorbar.

import matplotlib.pyplot as plt
import numpy as np; np.random.seed(1)

fig, (ax, cax) = plt.subplots(nrows=2,figsize=(4,4), 
                  gridspec_kw={"height_ratios":[1, 0.05]})
im = ax.imshow(np.random.rand(11,16))
ax.set_xlabel("x label")

fig.colorbar(im, cax=cax, orientation="horizontal")

plt.show()

np.log is ln, whereas np.log10 is your standard base 10 log.

You don't want git revert. That undoes a previous commit. You want git checkout to get git's version of the file from master.

git checkout -- filename.txt

In general, when you want to perform a git operation on a single file, use -- filename.

• git-checkout Documentation
• git-revert Documentation

2020 Update

Git introduced a new command git restore in version 2.23.0. Therefore, if you have git version 2.23.0+, you can simply git restore filename.txt - which does the same thing as git checkout -- filename.txt. The docs for this command do note that it is currently experimental.

This is to help anyone who comes here looking for a solution that wants a pure approach. I would recommend understanding this problem because it can happen in lots of different places not just with a JS Buffer object. By understanding why the problem exists and how to solve it you will improve your ability to solve other problems in the future since this one is so fundamental.

For those of us that have to deal with these problems in other languages it is quite natural to devise a solution, but there are people who may not realize how to abstract away the complexities and implement a generally efficient dynamic buffer. The code below may have potential to be optimized further.

I have left the read method unimplemented to keep the example small in size.

The realloc function in C (or any language dealing with intrinsic allocations) does not guarantee that the allocation will be expanded in size with out moving the existing data - although sometimes it is possible. Therefore most applications when needing to store a unknown amount of data will use a method like below and not constantly reallocate, unless the reallocation is very infrequent. This is essentially how most file systems handle writing data to a file. The file system simply allocates another node and keeps all the nodes linked together, and when you read from it the complexity is abstracted away so that the file/buffer appears to be a single contiguous buffer.

For those of you who wish to understand the difficulty in just simply providing a high performance dynamic buffer you only need to view the code below, and also do some research on memory heap algorithms and how the memory heap works for programs.

Most languages will provide a fixed size buffer for performance reasons, and then provide another version that is dynamic in size. Some language systems opt for a third-party system where they keep the core functionality minimal (core distribution) and encourage developers to create libraries to solve additional or higher level problems. This is why you may question why a language does not provide some functionality. This small core functionality allows costs to be reduced in maintaining and enhancing the language, however you end up having to write your own implementations or depending on a third-party.

};

    var can_write = length > (this.chunk_size - this.cur_size) ? (this.chunk_size - this.cur_size) : length;

    var lastbuf = this.buffer_list.length - 1;

    for (var x = 0; x < can_write; ++x) {
        this.buffer_list[lastbuf][this.cur_size + x] = data[x + offset];
    }

    this.cur_size += can_write;

Suppose you want to GET a webpage's content. The following code does it:

# -*- coding: utf-8 -*-
# python

# example of getting a web page

from urllib import urlopen
print urlopen("http://xahlee.info/python/python_index.html").read()

Well in general index is a B-tree. There are two types of indexes: clustered and nonclustered.

Clustered index creates a physical order of rows (it can be only one and in most cases it is also a primary key - if you create primary key on table you create clustered index on this table also).

Nonclustered index is also a binary tree but it doesn't create a physical order of rows. So the leaf nodes of nonclustered index contain PK (if it exists) or row index.

Indexes are used to increase the speed of search. Because the complexity is of O(log N). Indexes is very large and interesting topic. I can say that creating indexes on large database is some kind of art sometimes.

"$env:computername.$env:userdnsdomain" 

will work if separated out like this

"$env:computername"+"$env:userdnsdomain"

You can access those values with the global $_GET variable

//www.example.com/index.php?id=7
print $_GET['id']; // prints "7"

You should check all "incoming" user data - so here, that "id" is an INT. Don't use it directly in your SQL (vulnerable to SQL injections).

The same thing happened to me. Here is what I did in order to get it successfully installed. I downloaded KB2999226 update from Microsofts website here: https://www.microsoft.com/en-us/download/details.aspx?id=49093

After installing this package, I started the installation process again. That worked for me.

If You test app like me on localhost or You will have some problems with blank white page i use this:

ng build --prod --build-optimizer --base-href="http://127.0.0.1/my-app/"

Explanation:

ng build

Build app but in code there is many spaces, tabs and other stuff what makes code able be read by human. For server it isnt important how code looks. This is why i use:

ng build --prod --build-optimizer 

This make code out for production and reduce size [--build-optimizer] allow to reduce more code].

So at end i add --base-href="http://127.0.0.1/my-app/" to show application where is 'main frame' [in simple words]. With it You can have even multiple angular apps in any folder.

with function and single parameters:

    $ms = Person::where('name', 'Foo Bar');
    $persons = Person::order_by('list_order', 'ASC')->get();
    return $view->with(compact('ms', 'persons'));

with function and array parameter:

    $ms = Person::where('name', 'Foo Bar');
    $persons = Person::order_by('list_order', 'ASC')->get();
    $array = ['ms' => $ms, 'persons' => $persons];
    return $view->with($array);

For anyone who is trying to convert JSON to dictionary just for retrieving some value out of it. There is a simple way using Newtonsoft.JSON

using Newtonsoft.Json.Linq
...

JObject o = JObject.Parse(@"{
  'CPU': 'Intel',
  'Drives': [
    'DVD read/writer',
    '500 gigabyte hard drive'
  ]
}");

string cpu = (string)o["CPU"];
// Intel

string firstDrive = (string)o["Drives"][0];
// DVD read/writer

IList<string> allDrives = o["Drives"].Select(t => (string)t).ToList();
// DVD read/writer
// 500 gigabyte hard drive

Just use break, like that:

int cont = 0;
foreach (ListViewItem lvi in listView.Items) {
   if(cont==50) { //if listViewItem reach 50 break out.
      break; 
   }
   cont++;   //increment cont.
}

The "reference" Java implementation by Sean Leary is here on github. Make sure to have the latest version - different libraries pull in versions buggy old versions from 2009.

Java EE 7 has a JSON API in javax.json, see the Javadoc. From what I can tell, it doesn't have a simple method to marshall any object to JSON, you need to construct a JsonObject or a JsonArray.

import javax.json.*;

JsonObject value = Json.createObjectBuilder()
 .add("firstName", "John")
 .add("lastName", "Smith")
 .add("age", 25)
 .add("address", Json.createObjectBuilder()
     .add("streetAddress", "21 2nd Street")
     .add("city", "New York")
     .add("state", "NY")
     .add("postalCode", "10021"))
 .add("phoneNumber", Json.createArrayBuilder()
     .add(Json.createObjectBuilder()
         .add("type", "home")
         .add("number", "212 555-1234"))
     .add(Json.createObjectBuilder()
         .add("type", "fax")
         .add("number", "646 555-4567")))
 .build();

JsonWriter jsonWriter = Json.createWriter(...);
jsonWriter.writeObject(value);
jsonWriter.close();

But I assume the other libraries like GSON will have adapters to create objects implementing those interfaces.

I had the same issue, although the module that it was downloading was different. The only resolution to the problem is run the below command again:

npm install

string sTable="static class BinaryTable\r\n{";
string stemp = "";
for (int i = 0; i < 256; i++)
{
stemp = System.Convert.ToString(i, 2);
while(stemp.Length<8) stemp = "0" + stemp;
sTable += "\tconst char nb" + stemp + "=" + i.ToString() + ";\r\n";
}
sTable += "}";
Clipboard.Clear();
Clipboard.SetText ( sTable);
MessageBox.Show(sTable);

Using this, for 8bit binary, I use this to make a static class and it puts it into the clipboard.. Then it gets pasted into the project and added to the Using section, so anything with nb001010 is taken out of a table, at least static, but still... I use C# for a lot of PIC graphics coding and use 0b101010 a lot in Hi-Tech C

--sample from code outpt--

static class BinaryTable
{   const char nb00000000=0;
    const char nb00000001=1;
    const char nb00000010=2;
    const char nb00000011=3;
    const char nb00000100=4;
//etc, etc, etc, etc, etc, etc, etc, 
}

In Spring properties files, you can't just specify a number for this property. You also need to specify a unit. So you can say spring.mvc.async.request-timeout=5000ms or spring.mvc.async.request-timeout=5s, both of which will give you a 5-second timeout.

Just to add to BalusC's anwswer...

Invoking System.out.print("\b \b") repeatedly with a delay gives an exact same behavior as when we hit backspaces in {Windows 7 command console / Java 1.6}

$(this).value is attempting to call the 'value' property of a jQuery object, which does not exist. Native JavaScript does have a 'value' property on certain HTML objects, but if you are operating on a jQuery object you must access the value by calling $(this).val().

you need to convert to char first because converting to int adds those days to 1900-01-01

select CONVERT (datetime,convert(char(8),rnwl_efctv_dt ))

here are some examples

select CONVERT (datetime,5)

1900-01-06 00:00:00.000

select CONVERT (datetime,20100101)

blows up, because you can't add 20100101 days to 1900-01-01..you go above the limit

convert to char first

declare @i int
select @i = 20100101
select CONVERT (datetime,convert(char(8),@i))

I came back to this problem now that we are finalizing the game and I just thought to post what worked for me.

This is the method for rotating the Matrix:

this.matrix.reset();
this.matrix.setTranslate(this.floatXpos, this.floatYpos);
this.matrix.postRotate((float)this.direction, this.getCenterX(), this.getCenterY()); 

(this.getCenterX() is basically the bitmaps X position + the bitmaps width / 2)

And the method for Drawing the bitmap (called via a RenderManager Class):

canvas.drawBitmap(this.bitmap, this.matrix, null);

So it is prettey straight forward but I find it abit strange that I couldn't get it to work by setRotate followed by postTranslate. Maybe some knows why this doesn't work? Now all the bitmaps rotate properly but it is not without some minor decrease in bitmap quality :/

Anyways, thanks for your help!

This worked for me in a small test:

target.write(unicode(source.read(), sourceEncoding).encode(targetEncoding))
