For the Collatz problem, you can get a significant boost in performance by caching the "tails". This is a time/memory trade-off. See: memoization (https://en.wikipedia.org/wiki/Memoization). You could also look into dynamic programming solutions for other time/memory trade-offs.

Example python implementation:

import sys

inner_loop = 0

def collatz_sequence(N, cache):
    global inner_loop

    l = [ ]
    stop = False
    n = N

    tails = [ ]

    while not stop:
        inner_loop += 1
        tmp = n
        l.append(n)
        if n <= 1:
            stop = True  
        elif n in cache:
            stop = True
        elif n % 2:
            n = 3*n + 1
        else:
            n = n // 2
        tails.append((tmp, len(l)))

    for key, offset in tails:
        if not key in cache:
            cache[key] = l[offset:]

    return l

def gen_sequence(l, cache):
    for elem in l:
        yield elem
        if elem in cache:
            yield from gen_sequence(cache[elem], cache)
            raise StopIteration

if __name__ == "__main__":
    le_cache = {}

    for n in range(1, 4711, 5):
        l = collatz_sequence(n, le_cache)
        print("{}: {}".format(n, len(list(gen_sequence(l, le_cache)))))

    print("inner_loop = {}".format(inner_loop))

Try This!

I have added 5 circles you can add more. And instead of RaisedButton use InkResponse.

If you enter git commit but omit to enter a comment using the –m parameter, then Git will open up the default editor for you to edit your check-in note. By default that is Vim. Now you can do two things:

Alternative 1 – Exit Vim without entering any comment and repeat

A blank or unsaved comment will be counted as an aborted attempt to commit your changes and you can exit Vim by following these steps:

1. Press Esc to make sure you are not in edit mode (you can press Esc several times if you are uncertain)

2. Type :q! enter
   (that is, colon, letter q, exclamation mark, enter), this tells Vim to discard any changes and exit)
   Git will then respond:

   Aborting commit due to empty commit message

   and you are once again free to commit using:

   git commit –m "your comment here"
   

Alternative 2 – Use Vim to write a comment

Follow the following steps to use Vim for writing your comments

1. Press i to enter Edit Mode (or Insert Mode).
   That will leave you with a blinking cursor on the first line. Add your comment. Press Esc to make sure you are not in edit mode (you can press Esc several time if you are uncertain)
2. Type :wq enter
   (that is colon, letter w, letter q, enter), this will tell Vim to save changes and exit)

Response from https://blogs.msdn.microsoft.com/kristol/2013/07/02/the-git-command-line-101-for-windows-users/

In Oracle (atleast 11g) database :

If you hit

select to_char(SYSDATE,'Month') from dual;

It gives unformatted month name, with spaces, for e.g. May would be given as 'May '. The string May will have spaces.

In order to format month name, i.e to trim spaces, you need

select to_char(SYSDATE,'fmMonth') from dual;

This would return 'May'.

As a continuation on Matas' answer on benchmarking.

TL/DR: Exists() and Any() are equally fast.

First off: Benchmarking using Stopwatch is not precise (see series0ne's answer on a different, but similiar, topic), but it is far more precise than DateTime.

The way to get really precise readings is by using Performance Profiling. But one way to get a sense of how the two methods' performance measure up to each other is by executing both methods loads of times and then comparing the fastest execution time of each. That way, it really doesn't matter that JITing and other noise gives us bad readings (and it does), because both executions are "equally misguiding" in a sense.

static void Main(string[] args)
    {
        Console.WriteLine("Generating list...");
        List<string> list = GenerateTestList(1000000);
        var s = string.Empty;

        Stopwatch sw;
        Stopwatch sw2;
        List<long> existsTimes = new List<long>();
        List<long> anyTimes = new List<long>();

        Console.WriteLine("Executing...");
        for (int j = 0; j < 1000; j++)
        {
            sw = Stopwatch.StartNew();
            if (!list.Exists(o => o == "0123456789012"))
            {
                sw.Stop();
                existsTimes.Add(sw.ElapsedTicks);
            }
        }

        for (int j = 0; j < 1000; j++)
        {
            sw2 = Stopwatch.StartNew();
            if (!list.Exists(o => o == "0123456789012"))
            {
                sw2.Stop();
                anyTimes.Add(sw2.ElapsedTicks);
            }
        }

        long existsFastest = existsTimes.Min();
        long anyFastest = anyTimes.Min();

        Console.WriteLine(string.Format("Fastest Exists() execution: {0} ticks\nFastest Any() execution: {1} ticks", existsFastest.ToString(), anyFastest.ToString()));
        Console.WriteLine("Benchmark finished. Press any key.");
        Console.ReadKey();
    }

    public static List<string> GenerateTestList(int count)
    {
        var list = new List<string>();
        for (int i = 0; i < count; i++)
        {
            Random r = new Random();
            int it = r.Next(0, 100);
            list.Add(new string('s', it));
        }
        return list;
    }

After executing the above code 4 times (which in turn do 1 000 Exists() and Any() on a list with 1 000 000 elements), it's not hard to see that the methods are pretty much equally fast.

Fastest Exists() execution: 57881 ticks
Fastest Any() execution: 58272 ticks

Fastest Exists() execution: 58133 ticks
Fastest Any() execution: 58063 ticks

Fastest Exists() execution: 58482 ticks
Fastest Any() execution: 58982 ticks

Fastest Exists() execution: 57121 ticks
Fastest Any() execution: 57317 ticks

There is a slight difference, but it's too small a difference to not be explained by background noise. My guess would be that if one would do 10 000 or 100 000 Exists() and Any() instead, that slight difference would disappear more or less.

You need to make the x-factor into an ordered factor with the ordering you want, e.g

x <- data.frame("variable"=letters[1:5], "value"=rnorm(5)) ## example data
x <- x[with(x,order(-value)), ] ## Sorting
x$variable <- ordered(x$variable, levels=levels(x$variable)[unclass(x$variable)])

ggplot(x, aes(x=variable,y=value)) + geom_bar() +
   scale_y_continuous("",formatter="percent") + coord_flip()

I don't know any better way to do the ordering operation. What I have there will only work if there are no duplicate levels for x$variable.

Use git ls-remote git://github.com/<user>/<project>.git. For example, my trac-backlog project gives:

Just grep for the one you need and cut it out:

:: git ls-remote git://github.com/jszakmeister/trac-backlog.git | \
   grep refs/heads/master | cut -f 1
5d6a3c973c254378738bdbc85d72f14aefa316a0

Or, you can specify which refs you want on the command line and avoid the grep with:

:: git ls-remote git://github.com/jszakmeister/trac-backlog.git refs/heads/master | \
   cut -f 1
5d6a3c973c254378738bdbc85d72f14aefa316a0

Note: it doesn't have to be the git:// URL. It could be https:// or [email protected]: too.

Originally, this was geared towards finding out the latest commit of a remote branch (not just from your last fetch, but the actual latest commit in the branch on the remote repository). If you need the commit hash for something locally, the best answer is:

git rev-parse branch-name

It's fast, easy, and a single command. If you want the commit hash for the current branch, you can look at HEAD:

git rev-parse HEAD

You can try this code for checking which date value is the highest from two dates with a format MM/DD/YYYY:

function d_check() {
    var dl_sdt=document.getElementIdBy("date_input_Id1").value; //date one
    var dl_endt=document.getElementIdBy("date_input_Id2").value; //date two

    if((dl_sdt.substr(6,4)) > (dl_endt.substr(6,4))) {
        alert("first date is greater");
        return false;
    }

    else if((((dl_sdt.substr(0,2)) > (dl_endt.
        substr(0,2)))&&(frdt(dl_sdt.substr(3,2)) > (dl_endt.substr(3,2))))||
        (((dl_sdt.substr(0,2)) > (dl_endt.substr(0,2)))&&
        ((dl_sdt.substr(3,2)) < (dl_endt.substr(3,2))))||
        (((dl_sdt.substr(0,2)) == (dl_endt.substr(0,2)))&&((dl_sdt.substr(3,2)) > 
        (dl_endt.substr(3,2))))) {
            alert("first date is greater");
        return false;
    }

    alert("second date is digher");
    return true;
}

/*for checking this....create a form and give id's to two date inputs.The date format should be mm/dd/yyyy or mm-dd-yyyy or mm:dd:yyyy or mm.dd.yyyy like this. */

You can easily use a list to wrap the required object and that's all what django serializers need to correctly serialize it, eg.:

from django.core import serializers

# assuming obj is a model instance
serialized_obj = serializers.serialize('json', [ obj, ])

That's strange, it definitely works for me:

from matplotlib import pyplot as plt

plt.figure(figsize = (20,2))
plt.imshow(random.rand(8, 90), interpolation='nearest')

I am using the "MacOSX" backend, btw.

GIT uses colored output by default but on some system like as CentOS it is not enabled . You can enable it like this

git config --global color.ui  true 
git config --global color.ui  false 
git config --global color.ui  auto 

You can choose your required command from here .

Here --global is optional to apply action for every repository in your system . If you want to apply coloring for current repository only then you can do something like this -

 git config color.ui  true 

Note that according to the CSS3 spec, you do NOT have to wrap your layout in a table-style element. The browser will infer the existence of containing elements if they do not exist.

Since the values are actually inside of an HTML attribute, you should use '

"<img src='something' onmouseover='change(&apos;ex1&apos;)' />";

I would recommend separating out all of the foreign-key constraints from your CREATE TABLE statements. Create all the tables first without FK constraints, and then create all the FK constraints once you have created the tables.

You can add an FK constraint to a table using SQL like the following:

ALTER TABLE orders ADD CONSTRAINT orders_FK
  FOREIGN KEY (m_p_unique_id) REFERENCES library (m_p_unique_id);

In particular, your formats and library tables both have foreign-key constraints on one another. The two CREATE TABLE statements to create these two tables can never run successfully, as each will only work when the other table has already been created.

Separating out the constraint creation allows you to create tables with FK constraints on one another. Also, if you have an error with a constraint, only that constraint fails to be created. At present, because you have errors in the constraints in your CREATE TABLE statements, then entire table creation fails and you get various knock-on errors because FK constraints may depend on these tables that failed to create.

For clarity, I thought that a direct example of grabbing onto a resource can be shown from the following that I think contributes to the response for this question with a quick direct example.

private MenuItem menuItem_;

@Override
public boolean onCreateOptionsMenu(Menu menuF) 
{
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.menu_layout, menuF);
    menuItem_ = menuF.findItem(R.id.menu_item_identifier);
    return true;
}

In this case you hold onto a MenuItem reference at the beginning and then change the state of it (for icon state changes for example) at a later given point in time.

$('select').select2('enable',false);

This works for me.

+"\n" + can be added in print command to display the code block after it in next line

E.g. System.out.println ("a" + "\n" + "b") outputs a in first line and b in second line.

In XML there can be only one root element - you have two - heading and song.

If you restructure to something like:

<?xml version="1.0" encoding="UTF-8"?>
<song> 
 <heading>
 The Twelve Days of Christmas
 </heading>
 ....
</song>

The error about well-formed XML on the root level should disappear (though there may be other issues).

Just using plain JavaScript, this has been answered already: remove objects from array by object property.

Using underscore.js, you could combine .findWhere with .without:

var arr = [{_x000D_
  id: 1,_x000D_
  name: 'a'_x000D_
}, {_x000D_
  id: 2,_x000D_
  name: 'b'_x000D_
}, {_x000D_
  id: 3,_x000D_
  name: 'c'_x000D_
}];_x000D_
_x000D_
//substract third_x000D_
arr = _.without(arr, _.findWhere(arr, {_x000D_
  id: 3_x000D_
}));_x000D_
console.log(arr);

<script src="https://cdnjs.cloudflare.com/ajax/libs/underscore.js/1.8.3/underscore-min.js"></script>

Although, since you are creating a new array in this case anyway, you could simply use _.filter or the native Array.prototype.filter function (just like shown in the other question). Then you would only iterate over array once instead of potentially twice like here.

If you want to modify the array in-place, you have to use .splice. This is also shown in the other question and undescore doesn't seem to provide any useful function for that.

The two commands have the same effect (thanks to Robert Siemer’s answer for pointing it out).

The practical difference comes when using a local branch named differently:

• git checkout -b mybranch origin/abranch will create mybranch and track origin/abranch
• git checkout --track origin/abranch will only create 'abranch', not a branch with a different name.

(That is, as commented by Sebastian Graf, if the local branch did not exist already.
If it did, you would need git checkout -B abranch origin/abranch)

Note: with Git 2.23 (Q3 2019), that would use the new command git switch:

git switch -c <branch> --track <remote>/<branch>

If the branch exists in multiple remotes and one of them is named by the checkout.defaultRemote configuration variable, we'll use that one for the purposes of disambiguation, even if the <branch> isn't unique across all remotes.
Set it to e.g. checkout.defaultRemote=origin to always checkout remote branches from there if <branch> is ambiguous but exists on the 'origin' remote.

Here, '-c' is the new '-b'.

First, some background: Tracking means that a local branch has its upstream set to a remote branch:

# git config branch.<branch-name>.remote origin
# git config branch.<branch-name>.merge refs/heads/branch

git checkout -b branch origin/branch will:

• create/reset branch to the point referenced by origin/branch.
• create the branch branch (with git branch) and track the remote tracking branch origin/branch.

When a local branch is started off a remote-tracking branch, Git sets up the branch (specifically the branch.<name>.remote and branch.<name>.merge configuration entries) so that git pull will appropriately merge from the remote-tracking branch.
This behavior may be changed via the global branch.autosetupmerge configuration flag. That setting can be overridden by using the --track and --no-track options, and changed later using git branch --set-upstream-to.

And git checkout --track origin/branch will do the same as git branch --set-upstream-to):

 # or, since 1.7.0
 git branch --set-upstream upstream/branch branch
 # or, since 1.8.0 (October 2012)
 git branch --set-upstream-to upstream/branch branch
 # the short version remains the same:
 git branch -u upstream/branch branch

It would also set the upstream for 'branch'.

(Note: git1.8.0 will deprecate git branch --set-upstream and replace it with git branch -u|--set-upstream-to: see git1.8.0-rc1 announce)

Having an upstream branch registered for a local branch will:

• tell git to show the relationship between the two branches in git status and git branch -v.
• directs git pull without arguments to pull from the upstream when the new branch is checked out.

See "How do you make an existing git branch track a remote branch?" for more.

Two things:

Coding a linked list is, no doubt, a bit more work than using an array and he wondered what would justify the additional effort.

Never code a linked list when using C++. Just use the STL. How hard it is to implement should never be a reason to choose one data structure over another because most are already implemented out there.

As for the actual differences between an array and a linked list, the big thing for me is how you plan on using the structure. I'll use the term vector since that's the term for a resizable array in C++.

Indexing into a linked list is slow because you have to traverse the list to get to the given index, while a vector is contiguous in memory and you can get there using pointer math.

Appending onto the end or the beginning of a linked list is easy, since you only have to update one link, where in a vector you may have to resize and copy the contents over.

Removing an item from a list is easy, since you just have to break a pair of links and then attach them back together. Removing an item from a vector can be either faster or slower, depending if you care about order. Swapping in the last item over top the item you want to remove is faster, while shifting everything after it down is slower but retains ordering.

The best solution i can think of is by specifying your width and height in percent . This will allow you to rezise your screen based on your monitor size. its more of responsive layout..

For an instance. you have

<br/>
<div> . //This you set the width percent to %100
    <div> //This you set the width percent to any amount . if you put it by 50% , it will be half
    </div>
 </div>

This is the best option if you would want a responsive layout, i wouldnt recommend float , in certain cases float is okay to use. but in most cases , we avoid using float as it will affect a quite of number of things when you are doing cross-browser testing.

Hope this helps :)

Simple solution

<?php
   $x = 1;
     for($x = 1; $x < 8; $x++) {
        $x = $x + 1;
       echo $x;
     };    
?>

You can use functions in pyspark.sql.functions: functions like year, month, etc

Not saying this is better, just another way:

$("#elem")[0].style.fontSize="20px";

db.accommodations.find({"name":{"$exists":true, "$ne":[], "$not":{"$size":1}}})

Use the time package to work with time information in Go.

Time instants can be compared using the Before, After, and Equal methods. The Sub method subtracts two instants, producing a Duration. The Add method adds a Time and a Duration, producing a Time.

Play example:

package main

import (
    "fmt"
    "time"
)

func inTimeSpan(start, end, check time.Time) bool {
    return check.After(start) && check.Before(end)
}

func main() {
    start, _ := time.Parse(time.RFC822, "01 Jan 15 10:00 UTC")
    end, _ := time.Parse(time.RFC822, "01 Jan 16 10:00 UTC")

    in, _ := time.Parse(time.RFC822, "01 Jan 15 20:00 UTC")
    out, _ := time.Parse(time.RFC822, "01 Jan 17 10:00 UTC")

    if inTimeSpan(start, end, in) {
        fmt.Println(in, "is between", start, "and", end, ".")
    }

    if !inTimeSpan(start, end, out) {
        fmt.Println(out, "is not between", start, "and", end, ".")
    }
}

Variant of Tim's one, good only on some implementations of Regex: ^.*?_

var subjectString = "3.04_somename.jpg";
var resultString = Regex.Replace(subjectString,
    @"^   # Match start of string
    .*?   # Lazily match any character, trying to stop when the next condition becomes true
    _     # Match the underscore", "", RegexOptions.IgnorePatternWhitespace);

For storing a single row output into a variable from the select into query :

declare v_username varchare(20); SELECT username into v_username FROM users WHERE user_id = '7';

this will store the value of a single record into the variable v_username.

For storing multiple rows output into a variable from the select into query :

you have to use listagg function. listagg concatenate the resultant rows of a coloumn into a single coloumn and also to differentiate them you can use a special symbol. use the query as below SELECT listagg(username || ',' ) within group (order by username) into v_username FROM users;

public static String repeat(String str, int times) {
    int length = str.length();
    int size = length * times;
    char[] c = new char[size];
    for (int i = 0; i < size; i++) {
        c[i] = str.charAt(i % length);
    }
    return new String(c);
}

use auto and min or max width like this:

td {
max-width:50px;
width:auto;
min-width:10px;
}

@JoshAdel covered a lot of it, but if you just want to time the execution of an entire script, you can run it under time on a unix-like system.

kotai:~ chmullig$ cat sleep.py 
import time

print "presleep"
time.sleep(10)
print "post sleep"
kotai:~ chmullig$ python sleep.py 
presleep
post sleep
kotai:~ chmullig$ time python sleep.py 
presleep
post sleep

real    0m10.035s
user    0m0.017s
sys 0m0.016s
kotai:~ chmullig$ 

Try this method

It might be worth looking at a tutorial: MDN Canvas Tutorial

You can get the width and height of a canvas element simply by accessing those properties of the element. For example:

var canvas = document.getElementById('mycanvas');
var width = canvas.width;
var height = canvas.height;

If the width and height attributes are not present in the canvas element, the default 300x150 size will be returned. To dynamically get the correct width and height use the following code:

const canvasW = canvas.getBoundingClientRect().width;
const canvasH = canvas.getBoundingClientRect().height;

Or using the shorter object destructuring syntax:

const { width, height } = canvas.getBoundingClientRect();

The context is an object you get from the canvas to allow you to draw into it. You can think of the context as the API to the canvas, that provides you with the commands that enable you to draw on the canvas element.

I dont't know whether it was best to answer this as an answer or as a comment. I opted for the first option.

Regarding the poing PART IV: Forgotten Password Functionality in the first answer, I would make a point about Timing Attacks.

In the Remember your password forms, an attacker could potentially check a full list of emails and detect which are registered to the system (see link below).

Regarding the Forgotten Password Form, I would add that it is a good idea to equal times between successful and unsucessful queries with some delay function.

My navigation bar was not showing, so I have used the following method in Swift 2 iOS 9

let viewController = self.storyboard?.instantiateViewControllerWithIdentifier("Dashboard") as! Dashboard

// Creating a navigation controller with viewController at the root of the navigation stack.
let navController = UINavigationController(rootViewController: viewController)
self.presentViewController(navController, animated:true, completion: nil)

Since .net45 you can use the LeaveOpen constructor argument of StreamWriter and still use the using statement. Example:

using (var ms = new MemoryStream())
{
    using (var sw = new StreamWriter(ms, Encoding.UTF8, 1024, true))
    {
        sw.WriteLine("data");
        sw.WriteLine("data 2");    
    }

    ms.Position = 0;
    using (var sr = new StreamReader(ms))
    {
        Console.WriteLine(sr.ReadToEnd());
    }
}

You can try onload event as well;

var createIframe = function (src) {
        var self = this;
        $('<iframe>', {
            src: src,
            id: 'iframeId',
            frameborder: 1,
            scrolling: 'no',
            onload: function () {
                self.isIframeLoaded = true;
                console.log('loaded!');
            }
        }).appendTo('#iframeContainer');

    };

I know this is an old question, but the following should work if you don't need the month name at the DB level:

  SELECT EXTRACT(YEAR_MONTH FROM summaryDateTime) summary_year_month 
    FROM trading_summary  
GROUP BY summary_year_month;

See EXTRACT function docs

You will probably find this to be better performing.. and if you are building a JSON object in the application layer, you can do the formatting/ordering as you run through the results.

N.B. I wasn't aware you could add DESC to a GROUP BY clause in MySQL, perhaps you are missing an ORDER BY clause:

  SELECT EXTRACT(YEAR_MONTH FROM summaryDateTime) summary_year_month 
    FROM trading_summary  
GROUP BY summary_year_month
ORDER BY summary_year_month DESC;

Try using this:

$(".move_to").on("click", function(e){
    e.preventDefault();
    $('#contactsForm').attr('action', "/test1").submit();
});

Moving the order in which you use .preventDefault() might fix your issue. You also didn't use function(e) so e.preventDefault(); wasn't working.

Here it is working: http://jsfiddle.net/TfTwe/1/ - first of all, click the 'Check action attribute.' link. You'll get an alert saying undefined. Then click 'Set action attribute.' and click 'Check action attribute.' again. You'll see that the form's action attribute has been correctly set to /test1.

Console cons = System.console();

The above code line creates cons as a null reference. The code and output are given below:

Console cons = System.console();
if (cons != null) {
    System.out.println("Enter single character: ");
    char c = (char) cons.reader().read();
    System.out.println(c);
}else{
    System.out.println(cons);
}

Output :

null

The code was tested on macbook pro with java version "1.6.0_37"

You can use this:

select
    table_name,column_name,referenced_table_name,referenced_column_name
from
    information_schema.key_column_usage
where
    referenced_table_name is not null
    and table_schema = 'my_database' 
    and table_name = 'my_table'

Or for better formatted output use this:

select
    concat(table_name, '.', column_name) as 'foreign key',  
    concat(referenced_table_name, '.', referenced_column_name) as 'references'
from
    information_schema.key_column_usage
where
    referenced_table_name is not null
    and table_schema = 'my_database' 
    and table_name = 'my_table'

Since strings support adding, you can easily add your new style without overriding the current:

document.getElementById("myElement").style.cssText += `
   font-size: 12px;
   left: 200px;
   top: 100px;
`;

As many have mentioned previously, you must convert each column to string and then use the plus operator to combine two string columns. You can get a large performance improvement by using NumPy.

%timeit df['Year'].values.astype(str) + df.quarter
71.1 ms ± 3.76 ms per loop (mean ± std. dev. of 7 runs, 10 loops each)

%timeit df['Year'].astype(str) + df['quarter']
565 ms ± 22.3 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)

You need to escape the quotes in the string by adding a backslash \ before ".

Like:

"<font color=\"red\">"

In my case I was using it on localhost and forgot to change RewriteBase in .htaccess.

The advantages of an abstract class are:

• Ability to specify default implementations of methods
• Added invariant checking to functions
• Have slightly more control in how the "interface" methods are called
• Ability to provide behavior related or unrelated to the interface for "free"

Interfaces are merely data passing contracts and do not have these features. However, they are typically more flexible as a type can only be derived from one class, but can implement any number of interfaces.

Looks like oldDTE.MyDateTime was null, so constructor tried to take it's Value - which threw.

JPA 2.1 (finally) adds support for indexes and foreign keys! See this blog for details. JPA 2.1 is a part of Java EE 7, which is out .

If you like living on the edge, you can get the latest snapshot for eclipselink from their maven repository (groupId:org.eclipse.persistence, artifactId:eclipselink, version:2.5.0-SNAPSHOT). For just the JPA annotations (which should work with any provider once they support 2.1) use artifactID:javax.persistence, version:2.1.0-SNAPSHOT.

I'm using it for a project which won't be finished until after its release, and I haven't noticed any horrible problems (although I'm not doing anything too complex with it).

UPDATE (26 Sep 2013): Nowadays release and release candidate versions of eclipselink are available in the central (main) repository, so you no longer have to add the eclipselink repository in Maven projects. The latest release version is 2.5.0 but 2.5.1-RC3 is also present. I'd switch over to 2.5.1 ASAP because of issues with the 2.5.0 release (the modelgen stuff doesn't work).

I was facing the same problem when I was trying to connect Mysql to a Remote Server. I had found out that I had to change the bind-address to the current private IP address of the DB server. But when I was trying to add the bind-address =0.0.0.0 line in my.cnf file, it was not understanding the line when I tried to create a DB.

Upon searching, I found out the original place where bind-address was declared.

The actual declaration is in : /etc/mysql/mariadb.conf.d/50-server.cnf

Therefore I changed the bind-address directly there and then all seems working.

Why you are using row.Cells[row.Index]. You need to specify index of column you want to search (Problem #2). For example, you need to change row.Cells[row.Index] to row.Cells[2] where 2 is index of your column:

private void btnSearch_Click(object sender, EventArgs e)
{
    string searchValue = textBox1.Text;

    dgvProjects.SelectionMode = DataGridViewSelectionMode.FullRowSelect;
    try
    {
        foreach (DataGridViewRow row in dgvProjects.Rows)
        {
            if (row.Cells[2].Value.ToString().Equals(searchValue))
            {
                row.Selected = true;
                break;
            }
        }
    }
    catch (Exception exc)
    {
        MessageBox.Show(exc.Message);
    }
}

In short, decoupling success callback function from the ajax function so later you can add your own handlers without modifying the original code (observer pattern).

Ok, solved my problem, if anyone is passing by here is the answer:

Just had to add left: 0, and top: 0, to the styles, and yes, I'm tired.

position: 'absolute',
left:     0,
top:      0,

In web application a timer will be the best approach.

Just fyi, in desktop application I use this instead, inside an async method.

... 
Await Task.Run(Sub()
    System.Threading.Thread.Sleep(5000)
End Sub)
...

It work for me, importantly it doesn't freeze entire screen. But again this is on desktop, i try in web application it does freeze.

This is a derivative of @Ralph suggestion that I've been using. Add the c:url to the top of your JSP.

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<c:url value="/" var="root" />

Then just reference the root variable in your page:

I have found a couple of solutions to this.

Using Mapped Entities (JPA 2.0)

Using JPA 2.0 it is not possible to map a native query to a POJO, it can only be done with an entity.

For instance:

Query query = em.createNativeQuery("SELECT name,age FROM jedi_table", Jedi.class);
@SuppressWarnings("unchecked")
List<Jedi> items = (List<Jedi>) query.getResultList();

But in this case, Jedi, must be a mapped entity class.

An alternative to avoid the unchecked warning here, would be to use a named native query. So if we declare the native query in an entity

@NamedNativeQuery(
 name="jedisQry", 
 query = "SELECT name,age FROM jedis_table", 
 resultClass = Jedi.class)

Then, we can simply do:

TypedQuery<Jedi> query = em.createNamedQuery("jedisQry", Jedi.class);
List<Jedi> items = query.getResultList();

This is safer, but we are still restricted to use a mapped entity.

Manual Mapping

A solution I experimented a bit (before the arrival of JPA 2.1) was doing mapping against a POJO constructor using a bit of reflection.

public static <T> T map(Class<T> type, Object[] tuple){
   List<Class<?>> tupleTypes = new ArrayList<>();
   for(Object field : tuple){
      tupleTypes.add(field.getClass());
   }
   try {
      Constructor<T> ctor = type.getConstructor(tupleTypes.toArray(new Class<?>[tuple.length]));
      return ctor.newInstance(tuple);
   } catch (Exception e) {
      throw new RuntimeException(e);
   }
}

This method basically takes a tuple array (as returned by native queries) and maps it against a provided POJO class by looking for a constructor that has the same number of fields and of the same type.

Then we can use convenient methods like:

public static <T> List<T> map(Class<T> type, List<Object[]> records){
   List<T> result = new LinkedList<>();
   for(Object[] record : records){
      result.add(map(type, record));
   }
   return result;
}

public static <T> List<T> getResultList(Query query, Class<T> type){
  @SuppressWarnings("unchecked")
  List<Object[]> records = query.getResultList();
  return map(type, records);
}

And we can simply use this technique as follows:

Query query = em.createNativeQuery("SELECT name,age FROM jedis_table");
List<Jedi> jedis = getResultList(query, Jedi.class);

JPA 2.1 with @SqlResultSetMapping

With the arrival of JPA 2.1, we can use the @SqlResultSetMapping annotation to solve the problem.

We need to declare a result set mapping somewhere in a entity:

@SqlResultSetMapping(name="JediResult", classes = {
    @ConstructorResult(targetClass = Jedi.class, 
    columns = {@ColumnResult(name="name"), @ColumnResult(name="age")})
})

And then we simply do:

Query query = em.createNativeQuery("SELECT name,age FROM jedis_table", "JediResult");
@SuppressWarnings("unchecked")
List<Jedi> samples = query.getResultList();

Of course, in this case Jedi needs not to be an mapped entity. It can be a regular POJO.

Using XML Mapping

I am one of those that find adding all these @SqlResultSetMapping pretty invasive in my entities, and I particularly dislike the definition of named queries within entities, so alternatively I do all this in the META-INF/orm.xml file:

<named-native-query name="GetAllJedi" result-set-mapping="JediMapping">
    <query>SELECT name,age FROM jedi_table</query>
</named-native-query>

<sql-result-set-mapping name="JediMapping">
        <constructor-result target-class="org.answer.model.Jedi">
            <column name="name" class="java.lang.String"/>
            <column name="age" class="java.lang.Integer"/>
        </constructor-result>
    </sql-result-set-mapping>

And those are all the solutions I know. The last two are the ideal way if we can use JPA 2.1.

I have just tried to install that extension on my dev server.

First, make sure that the extension is correctly enabled. Your phpinfo() output doesn't seem complete.

If it is indeed installed properly, your phpinfo() should have a section that looks like this:

If you do not get that section in your phpinfo(). Make sure that you are using the right version. There are both non-thread-safe and thread-safe versions of the extension.

Finally, check your extension_dir setting. By default it's this: extension_dir = "ext", for most of the time it works fine, but if it doesn't try: extension_dir = "C:\PHP\ext".

===========================================================================

EDIT given new info:

You are using the wrong function. mssql_connect() is part of the Mssql extension. You are using microsoft's extension, so use sqlsrv_connect(), for the API for the microsoft driver, look at SQLSRV_Help.chm which should be extracted to your ext directory when you extracted the extension.

//img[@title='Modify'][i]

is short for

/descendant-or-self::node()/img[@title='Modify'][i]

hence is returning the i'th node under the same parent node.

You want

/descendant-or-self::img[@title='Modify'][i]

Create DataTable:

DataTable MyTable = new DataTable(); // 1
DataTable MyTableByName = new DataTable("MyTableName"); // 2

Add column to table:

 MyTable.Columns.Add("Id", typeof(int));
 MyTable.Columns.Add("Name", typeof(string));

Add row to DataTable method 1:

DataRow row = MyTable.NewRow();
row["Id"] = 1;
row["Name"] = "John";
MyTable.Rows.Add(row);

Add row to DataTable method 2:

MyTable.Rows.Add(2, "Ivan");

Add row to DataTable method 3 (Add row from another table by same structure):

MyTable.ImportRow(MyTableByName.Rows[0]);

Add row to DataTable method 4 (Add row from another table):

MyTable.Rows.Add(MyTable2.Rows[0]["Id"], MyTable2.Rows[0]["Name"]);

Add row to DataTable method 5 (Insert row at an index):

MyTable.Rows.InsertAt(row, 8);

Instead of this:

String char = name.substring(0,1); //char="a"

You should use the charAt() method.

char c = name.charAt(0); // c='a'
int ascii = (int)c;

If you don't want your data to be seen by the user, use a PHP session.

Data in a post request is still accessible (and manipulable) by the user.

Working solution:

string CSVFilePathName = APP_PATH + "Facilities.csv";
string[] Lines = File.ReadAllLines(CSVFilePathName);
string[] Fields;
Fields = Lines[0].Split(new char[] { ',' });
int Cols = Fields.GetLength(0);
DataTable dt = new DataTable();
//1st row must be column names; force lower case to ensure matching later on.
for (int i = 0; i < Cols-1; i++)
        dt.Columns.Add(Fields[i].ToLower(), typeof(string));
DataRow Row;
for (int i = 0; i < Lines.GetLength(0)-1; i++)
{
        Fields = Lines[i].Split(new char[] { ',' });
        Row = dt.NewRow();
        for (int f = 0; f < Cols-1; f++)
                Row[f] = Fields[f];
        dt.Rows.Add(Row);
}

Use str = ""+a+b+c;

Here the first + is String concat, so the result will be a String. Note where the "" lies is important.

Or (maybe) better, use a StringBuilder.

Since PyYAML's yaml.load() function parses YAML documents to native Python data structures, you can just access items by key or index. Using the example from the question you linked:

import yaml
with open('tree.yaml', 'r') as f:
    doc = yaml.load(f)

To access branch1 text you would use:

txt = doc["treeroot"]["branch1"]
print txt
"branch1 text"

because, in your YAML document, the value of the branch1 key is under the treeroot key.

private void WaitNSeconds(int seconds)
{
    if (seconds < 1) return;
    DateTime _desired = DateTime.Now.AddSeconds(seconds);
    while (DateTime.Now < _desired) {
         Thread.Sleep(1);
         System.Windows.Forms.Application.DoEvents();
    }
}

Here you go. this should work.

questionFrame.frame = CGRectMake(0 , 0, self.view.frame.width, self.view.frame.height * 0.7) 

answerFrame.frame =  CGRectMake(0 , self.view.frame.height * 0.7, self.view.frame.width, self.view.frame.height * 0.3)

you should convert test type >>>> test.tostring();

change the last line to this :

Label1.Text = "Du har nu lånat filmen:" + test.tostring();

Even though @JamesMcNellis answer is a valid one I would like to explain something about error handling and also the fact that there is another way of doing what you want.

You have four ways of accessing a specific item in a vector:

• Using the [] operator
• Using the member function at(...)
• Using an iterator in combination with a given offset
• Using std::for_each from the algorithm header of the standard C++ library. This is another way which I can recommend (it uses internally an iterator). You can read more about it for example here.

In the following examples I will be using the following vector as a lab rat and explaining the first three methods:

static const int arr[] = {1, 2, 3, 4};
std::vector<int> v(arr, arr+sizeof(arr)/sizeof(arr[0]));

This creates a vector as seen below:

1 2 3 4

First let's look at the [] way of doing things. It works in pretty much the same way as you expect when working with a normal array. You give an index and possibly you access the item you want. I say possibly because the [] operator doesn't check whether the vector actually has that many items. This leads to a silent invalid memory access. Example:

v[10] = 9;

This may or may not lead to an instant crash. Worst case is of course is if it doesn't and you actually get what seems to be a valid value. Similar to arrays this may lead to wasted time in trying to find the reason why for example 1000 lines of code later you get a value of 100 instead of 234, which is somewhat connected to that very location where you retrieve an item from you vector.

A much better way is to use at(...). This will automatically check for out of bounds behaviour and break throwing an std::out_of_range. So in the case when we have

v.at(10) = 9;

We will get:

terminate called after throwing an instance of 'std::out_of_range'
what(): vector::_M_range_check: __n (which is 10) >= this->size() (which is 4)

The third way is similar to the [] operator in the sense you can screw things up. A vector just like an array is a sequence of continuous memory blocks containing data of the same type. This means that you can use your starting address by assigning it to an iterator and then just add an offset to this iterator. The offset simply stands for how many items after the first item you want to traverse:

std::vector<int>::iterator it = v.begin(); // First element of your vector
*(it+0) = 9;  // offest = 0 basically means accessing v.begin()
// Now we have 9 2 3 4 instead of 1 2 3 4
*(it+1) = -1; // offset = 1 means first item of v plus an additional one
// Now we have 9 -1 3 4 instead of 9 2 3 4
// ...

As you can see we can also do

*(it+10) = 9;

which is again an invalid memory access. This is basically the same as using at(0 + offset) but without the out of bounds error checking.

I would advice using at(...) whenever possible not only because it's more readable compared to the iterator access but because of the error checking for invalid index that I have mentioned above for both the iterator with offset combination and the [] operator.

Drawable d = getResources().getDrawable(android.R.drawable.ic_dialog_email);
ImageView image = (ImageView)findViewById(R.id.image);
image.setImageDrawable(d);

var mystring = "hello World"
mystring = mystring.substring(0,1).toUpperCase() + 
mystring.substring(1,mystring.length)

console.log(mystring) //gives you Hello World

You can also do this with ant contrib's if task.

<if>
    <equals arg1="${condition}" arg2="true"/>
    <then>
        <copy file="${some.dir}/file" todir="${another.dir}"/>
    </then>
    <elseif>
        <equals arg1="${condition}" arg2="false"/>
        <then>
            <copy file="${some.dir}/differentFile" todir="${another.dir}"/>
        </then>
    </elseif>
    <else>
        <echo message="Condition was neither true nor false"/>
    </else>
</if>

Eventually, I decided to rebuild my Docker images, so that I change the root password by something I will know.

RUN echo 'root:Docker!' | chpasswd

or

RUN echo 'Docker!' | passwd --stdin root 

Well you can ask the help of regex, the great in here :)

code:

import re

string = 'adsfg34wrtwe4r2_()' #your string that needs to be matched.
regex = r'^[\w\d_()]*$' # you can also add a space in regex if u want to allow it in the string  
if re.match(regex,string):
    print 'yes'
else: 
    print 'false'

Output:

yes  

Hope this helps :)

in cmd set Visual Studio path depending upon ur version as

Visual Studio 2010 (VS10): SET VS90COMNTOOLS=%VS100COMNTOOLS%

Visual Studio 2012 (VS11): SET VS90COMNTOOLS=%VS110COMNTOOLS%

Visual Studio 2013 (VS12): SET VS90COMNTOOLS=%VS120COMNTOOLS%

In node-master( original node module downloaded from git ) run vcbuild.bat with admin privileges. vcbild.bat will generate windows related dependencies and will add folder name Release in node-master

Once it run it will take time to build the files.

Then in the directory having .gyp file use command

node-gyp rebuild --msvs_version=2012 --nodedir="Dive Name:\path to node-master\node-master"

this will build all the dependencies.

$date = strtotime('2016-2-3');
$date = date('l', $date);
var_dump($date)

(i added format 'l' so it will return full name of day)

Another option of course is to use Javascript (Jquery here):

$('.box1,.box2').each(function(){
    $(this).height($(this).parent().height());
})

It stands for permanent generation:

The permanent generation is special because it holds meta-data describing user classes (classes that are not part of the Java language). Examples of such meta-data are objects describing classes and methods and they are stored in the Permanent Generation. Applications with large code-base can quickly fill up this segment of the heap which will cause java.lang.OutOfMemoryError: PermGen no matter how high your -Xmx and how much memory you have on the machine.

try this=> numpy.array(yourvariable) followed by the command to compare, whatever you wish to.

I just ran into a similar issue and was able to fix it by waiting until the button was "clickable".

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

chrome_options = webdriver.ChromeOptions()
chrome_options.add_experimental_option('useAutomationExtension', False)
browser = webdriver.Chrome('./chromedriver', options=chrome_options)

browser.get(('YOURWEBSITEHERE.COM'))

button = WebDriverWait(browser, 10).until(EC.element_to_be_clickable((By.CSS_SELECTOR, 'button.dismiss')))
button.click()

You can't do it using environment variables directly. You need to use the set of "non standard" options that are passed to the java command. Run: java -X for details. The options you're looking for are -Xmx and -Xms (this is "initial" heap size, so probably what you're looking for.)

Some products like Ant or Tomcat might come with a batch script that looks for the JAVA_OPTS environment variable, but it's not part of the Java runtime. If you are using one of those products, you may be able to set the variable like:

set JAVA_OPTS="-Xms128m -Xmx256m"  

You can also take this approach with your own command line like:

set JAVA_OPTS="-Xms128m -Xmx256m"  
java ${JAVA_OPTS} MyClass

Option 1 - Android PCAP

Limitation

Android PCAP should work so long as:

Your device runs Android 4.0 or higher (or, in theory, the few devices which run Android 3.2). Earlier versions of Android do not have a USB Host API

Option 2 - TcpDump

Limitation

Phone should be rooted

Option 3 - bitshark (I would prefer this)

Limitation

Phone should be rooted

Reason - the generated PCAP files can be analyzed in WireShark which helps us in doing the analysis.

Other Options without rooting your phone

1. tPacketCapture

https://play.google.com/store/apps/details?id=jp.co.taosoftware.android.packetcapture&hl=en

Advantages

Using tPacketCapture is very easy, captured packet save into a PCAP file that can be easily analyzed by using a network protocol analyzer application such as Wireshark.

2. You can route your android mobile traffic to PC and capture the traffic in the desktop using any network sniffing tool.

One needs to understand what a JOIN or a series of JOINs does to a set of data. With strae's post, a pe_id of 1 joined with corresponding order and items on pe_id = 1 will give you the following data to "select" from:

[ table people portion ] [ table orders portion ] [ table items portion ]

| people.pe_id | people.pe_name | orders.ord_id | orders.pe_id | orders.ord_title | item.item_id | item.ord_id | item.pe_id | item.title |

| 1 | Foo | 1 | 1 | First order | 1 | 1 | 1 | Apple |
| 1 | Foo | 1 | 1 | First order | 2 | 1 | 1 | Pear |

The joins essentially come up with a cartesian product of all the tables. You basically have that data set to select from and that's why you need a distinct count on orders.ord_id and items.item_id. Otherwise both counts will result in 2 - because you effectively have 2 rows to select from.

I would follow official projects like tar as an example. In my opinion help msg. needs to be simple and descriptive as possible. Examples of use are good too. There is no real need for "standard help".

I added the com.fasterxml.jackson.datatype:jackson-datatype-jsr310:2.6.1 dependency and started to get the date in the following format:

"birthDate": [
    2016,
    1,
    25,
    21,
    34,
    55
  ]

which is not what I wanted but I was getting closer. I then added the following

spring.jackson.serialization.write_dates_as_timestamps=false

to application.properties file which gave me the correct format that I needed.

"birthDate": "2016-01-25T21:34:55"

Use Keystore Explorer gui - http://keystore-explorer.sourceforge.net/ - allows you to extract the private key from a .jks in various formats.

Try /public_html/stats/* ?

But since the files in git status reported as to be commited that means you've already added them manually. In which case, of course, it's a bit too late to ignore. You can git rm --cache them (IIRC).

Use the standard javascript Date class. No need for arrays. No need for extra libraries.

See https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/Date/toLocaleDateString

var options = {  weekday: 'long', year: 'numeric', month: 'long', day: 'numeric', hour: '2-digit', minute: '2-digit', second: '2-digit', hour12: false };_x000D_
var prnDt = 'Printed on ' + new Date().toLocaleTimeString('en-us', options);_x000D_
_x000D_
console.log(prnDt);

the plus works just fine, i personally prefer using the concat function.

var s = string.Concat(string 1, string 2, string, 3, etc)

If you can invert your logic you can use the Array.Clear() method to set the boolean array to false.

        int upperLimit = 21;
        double optimizeMe = Math.Sqrt(upperLimit);

        bool[] seiveContainer = new bool[upperLimit];
        Array.Clear(seiveContainer, 0, upperLimit);

Use SELECT to Insert records

INSERT tracking (userID, courseID, course, bookmark, course_date, posttest, post_attempts, post_score, post_date, complete, complete_date, exempted, exempted_date, exempted_reason, emailSent) 
SELECT userID, 11, course, bookmark, course_date, posttest, post_attempts, post_score, post_date, complete, complete_date, exempted, exempted_date, exempted_reason, emailSent
FROM tracking WHERE courseID = 6 AND course_date > '08-01-2008'

CTRL+SHIFT+C in Eclipse + StatET and Rstudio.

In the above solution, repeated here:

f = open('file.txt', 'r')

try:
    # do stuff with f
finally:
   f.close()

if something bad happens (you never know ...) after opening the file successfully and before the try, the file will not be closed, so a safer solution is:

f = None
try:
    f = open('file.txt', 'r')

    # do stuff with f

finally:
    if f is not None:
       f.close()

In general, that's not how systems use GET requests. So, it will be hard to get your libraries to play along. In fact, the spec says that "If the request method is a case-sensitive match for GET or HEAD act as if data is null." So, I think you are out of luck unless the browser you are using doesn't respect that part of the spec.

You can probably setup an endpoint on your own server for a POST ajax request, then redirect that in your server code to a GET request with a body.

If you aren't absolutely tied to GET requests with the body being the data, you have two options.

POST with data: This is probably what you want. If you are passing data along, that probably means you are modifying some model or performing some action on the server. These types of actions are typically done with POST requests.

GET with query string data: You can convert your data to query string parameters and pass them along to the server that way.

I'm not fluent in English

but if I understand the problem, is it that locally in the project you have an older version of CLI than globally?

And would you like to use this global newer instead of the local older one?

If so, a very simple method is enough to run in the project directory npm link @angular/cli

Someone should mention that in the question there is a little trap. #ifdef will only check if the following symbol has been defined via #define or by command line, but its value (its substitution in fact) is irrelevant. You could even write

#define one

precompilers accept that. But if you use #if it's another thing.

#define one 0
#if one
    printf("one evaluates to a truth ");
#endif
#if !one
    printf("one does not evaluate to truth ");
#endif

will give one does not evaluate to truth. The keyword defined allows to get the desired behaviour.

#if defined(one) 

is therefore equivalent to #ifdef

The advantage of the #if construct is to allow a better handling of code paths, try to do something like that with the old #ifdef/#ifndef pair.

#if defined(ORA_PROC) || defined(__GNUC) && __GNUC_VERSION > 300

I have a slightly simplified answer for this (with just the PreviewMouseLeftButtonDown event) which seems to mimic the usual functionality of a browser:

In XAML you have a TextBox say:

<TextBox Text="http://www.blabla.com" BorderThickness="2" BorderBrush="Green" VerticalAlignment="Center" Height="25"
                 PreviewMouseLeftButtonDown="SelectAll" />

In codebehind:

private void SelectAll(object sender, MouseButtonEventArgs e)
{
    TextBox tb = (sender as TextBox);

    if (tb == null)
    {
        return;
    }

    if (!tb.IsKeyboardFocusWithin)
    {
        tb.SelectAll();
        e.Handled = true;
        tb.Focus();
    }
}

When I ran into this error, I spent hours trying to find a solution.

My issue was that when I went to save the file I had accidentally hit the key stroke "G" in the web.config. I had a straggler Character just sittings outside, so the web.config did not know how to interpret the improperly formatted data.

Hope this helps.

In case you prefer to use jQuery to set the image from Base64:

$("#img").attr('src', 'data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO9TXL0Y4OHwAAAABJRU5ErkJggg==');

Example for random number in between 10 (0-9);

import UIKit

let randomNumber = Int(arc4random_uniform(10))

Very easy code - simple and short.

The code you provided would print the number of tabs, not the number of spaces. The below function should count the number of whitespace characters in a given string.

int countSpaces(String string) {
    int spaces = 0;
    for(int i = 0; i < string.length(); i++) {
        spaces += (Character.isWhitespace(string.charAt(i))) ? 1 : 0;
    }
    return spaces;
}

Update 2019

I tried easy_install at first but it doesn't install packages in a clean and intuitive way. Also when it comes time to remove packages it left a lot of artifacts that needed to be cleaned up.

sudo yum install epel-release
sudo yum install python34-pip
pip install package

Was the solution that worked for me, it installs "pip3" as pip on the system. It also uses standard rpm structure so it clean in its removal. I am not sure what process you would need to take if you want both python2 and python3 package manager on your system.

var list = new List<string> { "One", "Two", "Three" };

Essentially the syntax is:

new List<Type> { Instance1, Instance2, Instance3 };

Which is translated by the compiler as

List<string> list = new List<string>();
list.Add("One");
list.Add("Two");
list.Add("Three");

Here is a sample:

You can direct the subprocess output to the streams directly. Simplified example:

subprocess.run(['ls'], stderr=sys.stderr, stdout=sys.stdout)

dat1 and dat2 are Strings in JavaScript. There is no getTime function on the String prototype. I believe you want the Date.parse() function: http://www.w3schools.com/jsref/jsref_parse.asp

You would use it like this:

var date = Date.parse(dat1);

I assume you are using Series.plot() to plot your data. If you look at the docs for Series.plot() here:

http://pandas.pydata.org/pandas-docs/dev/generated/pandas.Series.plot.html

there is no color parameter listed where you might be able to set the colors for your bar graph.

However, the Series.plot() docs state the following at the end of the parameter list:

kwds : keywords
Options to pass to matplotlib plotting method

What that means is that when you specify the kind argument for Series.plot() as bar, Series.plot() will actually call matplotlib.pyplot.bar(), and matplotlib.pyplot.bar() will be sent all the extra keyword arguments that you specify at the end of the argument list for Series.plot().

If you examine the docs for the matplotlib.pyplot.bar() method here:

http://matplotlib.org/api/pyplot_api.html#matplotlib.pyplot.bar

..it also accepts keyword arguments at the end of it's parameter list, and if you peruse the list of recognized parameter names, one of them is color, which can be a sequence specifying the different colors for your bar graph.

Putting it all together, if you specify the color keyword argument at the end of your Series.plot() argument list, the keyword argument will be relayed to the matplotlib.pyplot.bar() method. Here is the proof:

import pandas as pd
import matplotlib.pyplot as plt

s = pd.Series(
    [5, 4, 4, 1, 12],
    index = ["AK", "AX", "GA", "SQ", "WN"]
)

#Set descriptions:
plt.title("Total Delay Incident Caused by Carrier")
plt.ylabel('Delay Incident')
plt.xlabel('Carrier')

#Set tick colors:
ax = plt.gca()
ax.tick_params(axis='x', colors='blue')
ax.tick_params(axis='y', colors='red')

#Plot the data:
my_colors = 'rgbkymc'  #red, green, blue, black, etc.

pd.Series.plot(
    s, 
    kind='bar', 
    color=my_colors,
)

plt.show()

Note that if there are more bars than colors in your sequence, the colors will repeat.

It's quite simple actually if you're using PostgreSQL, just use distinct(columns) (documentation).

Productorder.objects.all().distinct('category')

Note that this feature has been included in Django since 1.4

The standard method to generate a number (without a utility method) in a range is to just use the double with the range:

long range = 1234567L;
Random r = new Random()
long number = (long)(r.nextDouble()*range);

will give you a long between 0 (inclusive) and range (exclusive). Similarly if you want a number between x and y:

long x = 1234567L;
long y = 23456789L;
Random r = new Random()
long number = x+((long)(r.nextDouble()*(y-x)));

will give you a long from 1234567 (inclusive) through 123456789 (exclusive)

Note: check parentheses, because casting to long has higher priority than multiplication.

A method for future reference is something like this. bannedphraseform is the first form and expectedphraseform is the second. If the first one is hit, the second one is skipped (which is a reasonable assumption in this case):

if request.method == 'POST':
    bannedphraseform = BannedPhraseForm(request.POST, prefix='banned')
    if bannedphraseform.is_valid():
        bannedphraseform.save()
else:
    bannedphraseform = BannedPhraseForm(prefix='banned')

if request.method == 'POST' and not bannedphraseform.is_valid():
    expectedphraseform = ExpectedPhraseForm(request.POST, prefix='expected')
    bannedphraseform = BannedPhraseForm(prefix='banned')
    if expectedphraseform.is_valid():
        expectedphraseform.save()

else:
    expectedphraseform = ExpectedPhraseForm(prefix='expected')

Use the "+" symbol to cast a string to a number.

window.location.hash = +page_number;

CTRL+Space

You can't do it with pure html/javascript. This is because you have a seperate connection to the webserver to retrieve a separate file (the image) and a normal webserver will serve the file with content headers set so that the browser reading the content type will decide that the type can be handled internally.

The way to force the browser not to handle the file internally is to change the headers (content-disposition prefereably, or content-type) so the browser will not try to handle the file internally. You can either do this by writing a script on the webserver that dynamically sets the headers (i.e. download.php) or by configuring the webserver to return different headers for the file you want to download. You can do this on a per-directory basis on the webserver, which would allow you to get away without writing any php or javascript - simply have all your download images in that one location.

system "sleep 0.1";

does the trick.

Use directly

$paymentDate = strtotime(date("d-m-Y"));
$contractDateBegin = strtotime("01-01-2001");
$contractDateEnd = strtotime("01-01-2015");

Then comparison will be ok cause your 01-01-2015 is valid for PHP's 32bit date-range, stated in strtotime's manual.

git checkout master
git pull

should do the job.

You will get the "Your branch is behind" message every time when you work on a branch different than master, someone does changes to master and you git pull.

(branch) $ //hack hack hack, while someone push the changes to origin/master
(branch) $ git pull   

now the origin/master reference is pulled, but your master is not merged with it

(branch) $ git checkout master
(master) $ 

now master is behind origin/master and can be fast forwarded

this will pull and merge (so merge also newer commits to origin/master)
(master) $ git pull 

this will just merge what you have already pulled
(master) $ git merge origin/master

now your master and origin/master are in sync

Alternativly if your using bootstrap then you can just add align-middle to vertical align the element.

<button id="whaever" class="btn btn-large btn-primary" style="padding: 20px;" name="Continue" type="submit">Continue
    <i class="icon-ok align-middle" style="font-size:40px;"></i>
</button>

1. Open SQL Server Management Studio
2. Connect to the database engine for which you need the port number

3. Run the below query against the database

   select distinct local_net_address, local_tcp_port from sys.dm_exec_connections where local_net_address is not null

The above query shows the local IP as well as the listening Port number

You can always just use antecedent numbers to repeat actions:

• In visual mode, type 35↓ and the cursor will move down 35 times, selecting the next 35 lines
• In normal mode:
  • delete 35 lines 35dd
  • paste 35 times 35p
  • undo 35 changes 35u
  • etc.

You need to add the python.exe in C://.../Anaconda3 installation file as well as C://.../Anaconda3/Scripts to PATH.

First go to your installation directory, in my case it is installed in C://Users/user/Anaconda3 and shift+right click and press "Open command window here" or it might be "Open powershell here", if it is powershell, just write cmd and hit enter to run command window. Then run the following command setx PATH %cd%

Then go to C://Users/user/Anaconda3/Scripts and open the command window there as above, then run the same command "setx PATH %cd%"

Bash -ge 4 has the mapfile builtin to read lines from the standard input into an array variable.

help mapfile 

mapfile < file.txt lines
printf "%s" "${lines[@]}"

mapfile -t < file.txt lines    # strip trailing newlines
printf "%s\n" "${lines[@]}" 

See also:

http://bash-hackers.org/wiki/doku.php/commands/builtin/mapfile

If you just want the list, then you should ask here: http://unix.stackexchange.com

The answer is: cd / && find -name *.js

If you want to implement this, you have to specify the language.

No, because RAND_MAX is typically expanded to MAX_INT. So adding one (apparently) puts it at MIN_INT (although it should be undefined behavior as I'm told), hence the reversal of sign.

To get what you want you will need to move the +1 outside the computation:

r = ((double) rand() / (RAND_MAX)) + 1;

You can do it with the options

echo   $form->field($model, 'hidden1', 
      ['options' => ['value'=> 'your value'] ])->hiddenInput()->label(false);

In addition to above differences following are few more:

1. RV separates view creation and binding of data to view. In LV, you need to check if convertView is null or not for creating view, before binding data to it. So, in case of RV, view will be created only when it is needed but in case of LV, one can miss the check for convertview and will create view everytime.

2. Switching between Grid and List is more easy now with LayoutManager.

3. No need to notify and update all items, even if only single item is changed.

4. One had to implement view caching in case of LV. It is provided in RV by default. (There is difference between view caching n recycling.)

5. Very easy item animations in case of RV.

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

I fixed this error on Ubuntu by carefully following the instructions for installing R. This included:

1. adding deb http://cran.utstat.utoronto.ca/bin/linux/ubuntu trusty/ to my /etc/apt/sources.list file
2. Running sudo apt-get update
3. Running sudo apt-get install r-base-dev

For step 1 you can chose any CRAN download mirror in place of my University of Toronto one if you would like.

laravel artisan does not support default model and view generation. check this provider https://github.com/JeffreyWay/Laravel-4-Generators to generate models, views, seeder etc.

What exactly are you planning on doing with it (what you want to do makes a difference with what you will need to call).

hashCode, as defined in the JavaDocs, says:

As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the Java™ programming language.)

So if you are using hashCode() to find out if it is a unique object in memory that isn't a good way to do it.

System.identityHashCode does the following:

Returns the same hash code for the given object as would be returned by the default method hashCode(), whether or not the given object's class overrides hashCode(). The hash code for the null reference is zero.

Which, for what you are doing, sounds like what you want... but what you want to do might not be safe depending on how the library is implemented.

In addition to configuration changes on your WWW server to handle the new subdomain, your code would need to be making changes to your DNS records. So, unless you're running your own BIND (or similar), you'll need to figure out how to access your name server provider's configuration. If they don't offer some sort of API, this might get tricky.

Update: yes, I would check with your registrar if they're also providing the name server service (as is often the case). I've never explored this option before but I suspect most of the consumer registrars do not. I Googled for GoDaddy APIs and GoDaddy DNS APIs but wasn't able to turn anything up, so I guess the best option would be to check out the online help with your provider, and if that doesn't answer the question, get a hold of their support staff.

No. The method for appending an entire sequence is list.extend().

>>> L = [1, 2]
>>> L.extend((3, 4, 5))
>>> L
[1, 2, 3, 4, 5]

You could also use...

$hostname = getenv('HTTP_HOST');

For me, none of the offered solutions worked. It turns out that I was using different settings for migration (manage.py) and running (wsgi.py). Settings defined in manage.py used a local database however a production database was used in wsgi.py settings. Thus a production database was never migrated. Using:

django-admin migrate

for migration proved to be better as you have to specify the settings used as here.

• Make sure that when migrating you always use the same database as when running!

You need to download this from Microsoft: http://www.microsoft.com/en-us/download/details.aspx?id=7435.

The tool is called "Microsoft URL Rewrite Module 2.0 for IIS 7" and is described as follows by Microsoft: "URL Rewrite Module 2.0 provides a rule-based rewriting mechanism for changing requested URL’s before they get processed by web server and for modifying response content before it gets served to HTTP clients"

Negative top margins can achieve this effect, but they would need to be customized for each page. For instance, this markup...

<div class="product">
<h2>Greatest Product Ever</h2>
<p class="desc">This paragraph appears in the source code directly after the heading and will appear in the search results.</p>
<p class="sidenote">Note: This information appears in HTML after the product description appearing below.</p>
</div>

...and this CSS...

.product { width: 400px; }
.desc { margin-top: 5em; }
.sidenote { margin-top: -7em; }

...would allow you to pull the second paragraph above the first.

Of course, you'll have to manually tweak your CSS for different description lengths so that the intro paragraph jumps up the appropriate amount, but if you have limited control over the other parts and full control over markup and CSS then this might be an option.

Did you try

for line in open("masters", "r").readlines(): print line

?

readline() 

only reads "a line", on the other hand

readlines()

reads whole lines and gives you a list of all lines.

Using javascript I developed a solution. It isn't beautiful but it worked for me:

function drawMultilineText(){

    // set context and formatting   
    var context = document.getElementById("canvas").getContext('2d');
    context.font = fontStyleStr;
    context.textAlign = "center";
    context.textBaseline = "top";
    context.fillStyle = "#000000";

    // prepare textarea value to be drawn as multiline text.
    var textval = document.getElementByID("textarea").value;
    var textvalArr = toMultiLine(textval);
    var linespacing = 25;
    var startX = 0;
    var startY = 0;

    // draw each line on canvas. 
    for(var i = 0; i < textvalArr.length; i++){
        context.fillText(textvalArr[i], x, y);
        y += linespacing;
    }
}

// Creates an array where the <br/> tag splits the values.
function toMultiLine(text){
   var textArr = new Array();
   text = text.replace(/\n\r?/g, '<br/>');
   textArr = text.split("<br/>");
   return textArr;
}

Hope that helps!

One problem with StringWriter is that by default it doesn't let you set the encoding which it advertises - so you can end up with an XML document advertising its encoding as UTF-16, which means you need to encode it as UTF-16 if you write it to a file. I have a small class to help with that though:

public sealed class StringWriterWithEncoding : StringWriter
{
    public override Encoding Encoding { get; }

    public StringWriterWithEncoding (Encoding encoding)
    {
        Encoding = encoding;
    }    
}

Or if you only need UTF-8 (which is all I often need):

public sealed class Utf8StringWriter : StringWriter
{
    public override Encoding Encoding => Encoding.UTF8;
}

As for why you couldn't save your XML to the database - you'll have to give us more details about what happened when you tried, if you want us to be able to diagnose/fix it.

The HTTP 502 "Bad Gateway" response is generated when Apache web server does not receive a valid HTTP response from the upstream server, which in this case is your Tomcat web application.

Some reasons why this might happen:

• Tomcat may have crashed
• The web application did not respond in time and the request from Apache timed out
• The Tomcat threads are timing out
• A network device is blocking the request, perhaps as some sort of connection timeout or DoS attack prevention system

If the problem is related to timeout settings, you may be able to resolve it by investigating the following:

• ProxyTimeout directive of Apache's mod_proxy
• Connector config of Apache Tomcat
• Your network device's manual

Use this:

In [105]: a
Out[105]: 
array([[15, 30, 88, 31, 33],
       [53, 38, 54, 47, 56],
       [67,  2, 74, 10, 16],
       [86, 33, 15, 51, 32],
       [32, 47, 76, 15, 81]], dtype=int32)

In [106]: float32(a)
Out[106]: 
array([[ 15.,  30.,  88.,  31.,  33.],
       [ 53.,  38.,  54.,  47.,  56.],
       [ 67.,   2.,  74.,  10.,  16.],
       [ 86.,  33.,  15.,  51.,  32.],
       [ 32.,  47.,  76.,  15.,  81.]], dtype=float32)

I am assuming that you have used height attribute at both so i am comparing it with a height left do it with JavaScript.

var right=document.getElementById('rightdiv').style.height;
var left=document.getElementById('leftdiv').style.height;
if(left>right)
{
    document.getElementById('rightdiv').style.height=left;
}
else
{
    document.getElementById('leftdiv').style.height=right;
}

Another idea can be found here HTML/CSS: Making two floating divs the same height.

You can add:

-ErrorVariable errvar

And then look in $errvar.

One can do it like this as well

#!/bin/bash
# script_name function_test.sh
function argument(){
for i in $@;do
    echo $i
done;
}
argument $@

Now call your script like

./function_test.sh argument1 argument2

You can use AngularJS build-in service $rootScope and inject this service in both of your controllers. You can then listen for events that are fired on $rootScope object.

$rootScope provides two event dispatcher called $emit and $broadcast which are responsible for dispatching events(may be custom events) and use $rootScope.$on function to add event listener.

You're using the exec form of ENTRYPOINT. Unlike the shell form, the exec form does not invoke a command shell. This means that normal shell processing does not happen. For example, ENTRYPOINT [ "echo", "$HOME" ] will not do variable substitution on $HOME. If you want shell processing then either use the shell form or execute a shell directly, for example: ENTRYPOINT [ "sh", "-c", "echo $HOME" ].
When using the exec form and executing a shell directly, as in the case for the shell form, it is the shell that is doing the environment variable expansion, not docker.(from Dockerfile reference)

In your case, I would use shell form

ENTRYPOINT ./greeting --message "Hello, $ADDRESSEE\!"

Like this, using .limit():

var q = models.Post.find({published: true}).sort('date', -1).limit(20);
q.execFind(function(err, posts) {
  // `posts` will be of length 20
});

In my case I had to uninstall hyper-v, restart pc, and run docker again.

Probably you try to send your data from mydomain.com to www.mydomain.com or reverse, NOTE you missed "www". http://mydomain.com and http://www.mydomain.com are different domains to javascript.

Empty strings and nulls are fundamentally different. A null is an absence of a value and an empty string is a value that is empty.

The programming language making assumptions about the "value" of a variable, in this case an empty string, will be as good as initiazing the string with any other value that will not cause a null reference problem.

Also, if you pass the handle to that string variable to other parts of the application, then that code will have no ways of validating whether you have intentionally passed a blank value or you have forgotten to populate the value of that variable.

Another occasion where this would be a problem is when the string is a return value from some function. Since string is a reference type and can technically have a value as null and empty both, therefore the function can also technically return a null or empty (there is nothing to stop it from doing so). Now, since there are 2 notions of the "absence of a value", i.e an empty string and a null, all the code that consumes this function will have to do 2 checks. One for empty and the other for null.

In short, its always good to have only 1 representation for a single state. For a broader discussion on empty and nulls, see the links below.

https://softwareengineering.stackexchange.com/questions/32578/sql-empty-string-vs-null-value

Having used a laptop with BitLocker enabled for almost 2 years now with more or less similar specs (although without the SSD unfortunately), I can say that it really isn't that bad, or even noticable. Although I have not used this particular machine without BitLocker enabled, it really does not feel sluggish at all when compared to my desktop machine (dual core, 16 GB, dual Raptor disks, no BitLocker). Building large projects might take a bit longer, but not enough to notice.

To back this up with more non-scientifical "proof": many of my co-workers used their machines intensively without BitLocker before I joined the company (it became mandatory to use it around the time I joined, even though I am pretty sure the two events are totally unrelated), and they have not experienced noticable performance degradation either.

For me personally, having an "always on" solution like BitLocker beats manual steps for encryption, hands-down. Bitlocker-to-go (new on Windows 7) for USB devices on the other hand is simply too annoying to work with, since you cannot easily exchange information with non-W7 machines. Therefore I use TrueCrypt for removable media.

b = { 'video':0, 'music':23,"picture":12 } 
random.choice(tuple(b.items())) ('music', 23) 
random.choice(tuple(b.items())) ('music', 23) 
random.choice(tuple(b.items())) ('picture', 12) 
random.choice(tuple(b.items())) ('video', 0) 

Laravel's Autoload is a bit different:

1) It will in fact use Composer for some stuff

2) It will call Composer with the optimize flag

3) It will 'recompile' loads of files creating the huge bootstrap/compiled.php

4) And also will find all of your Workbench packages and composer dump-autoload them, one by one.

The error Event the onerror handler receives is a simple event not containing such information:

If the user agent was required to fail the WebSocket connection or the WebSocket connection is closed with prejudice, fire a simple event named error at the WebSocket object.

You may have better luck listening for the close event, which is a CloseEvent and indeed has a CloseEvent.code property containing a numerical code according to RFC 6455 11.7 and a CloseEvent.reason string property.

Please note however, that CloseEvent.code (and CloseEvent.reason) are limited in such a way that network probing and other security issues are avoided.

Basically you can put HTML anywhere outside of PHP tags. It's also very beneficial to do all your necessary data processing before displaying any data, in order to separate logic and presentation.

The data display itself could be at the bottom of the same PHP file or you could include a separate PHP file consisting of mostly HTML.

I prefer this compact style:

<?php
    /* do your processing here */
?>

<html>
<head>
    <title><?=$title?></title>
</head>
<body>
    <?php foreach ( $something as $item ) : ?>
        <p><?=$item?></p>
    <?php endforeach; ?>
</body>
</html>

Note: you may need to use <?php echo $var; ?> instead of <?=$var?> depending on your PHP setup.

Is this a commercial application or some hobbyist / open source software?

I'm asking this because in my experience, all free .NET Excel handling alternatives have serious problems, for different reasons. For hobbyist things, I usually end up porting jExcelApi from Java to C# and using it.

But if this is a commercial application, you would be better off by purchasing a third party library, like Aspose.Cells. Believe me, it totally worths it as it saves a lot of time and time ain't free.

You can set the following environment variable:

PIP_TARGET=/path/to/pip/dir

I looked at the HTML generated by the UI Dialog. It renders buttons pane like this:

<div class="ui-dialog-buttonpane ui-widget-content ui-helper-clearfix">
     <button type="button" class="ui-state-default ui-corner-all">Delete all items in recycle bin</button>
     <button type="button" class="ui-state-default ui-corner-all different" style="border: 1px solid blue;">Cancel</button>
</div>

Adding a class to Cancel button should be easy.

$('.ui-dialog-buttonpane :last-child').css('background-color', '#ccc');

This will make the Cancel button little grey. You can style this button however you like.

Above code assumes that the Cancel button is the last button. The fool proof way to do it would be

$('.ui-dialog-buttonpane :button')
    .each(
        function()
        { 
            if($(this).text() == 'Cancel')
            {
                //Do your styling with 'this' object.
            }
        }
    );

Any line starting with a "REM" is treated as a comment, nothing is executed including the redirection.

Also, the %date% variable may contain "/" characters which are treated as path separator characters, leading to the system being unable to create the desired log file.

It would be easier to make suggestions if you provided example code and data.

Accessing the dictionary is unlikely to be a problem as that operation is O(1) on average, and O(N) amortized worst case. It's possible that the built-in hashing functions are experiencing collisions for your data. If you're having problems with has the built-in hashing function, you can provide your own.

Python's dictionary implementation reduces the average complexity of dictionary lookups to O(1) by requiring that key objects provide a "hash" function. Such a hash function takes the information in a key object and uses it to produce an integer, called a hash value. This hash value is then used to determine which "bucket" this (key, value) pair should be placed into.

You can overwrite the __hash__ method in your class to implement a custom hash function like this:

def __hash__(self):    
    return hash(str(self))

Depending on what your data actually looks like, you might be able to come up with a faster hash function that has fewer collisions than the standard function. However, this is unlikely. See the Python Wiki page on Dictionary Keys for more information.

For those who are using postgresql db and facing error

You can try this code for Swift

 let popup : PopupVC = self.storyboard?.instantiateViewControllerWithIdentifier("PopupVC") as! PopupVC
 let navigationController = UINavigationController(rootViewController: popup)
 navigationController.modalPresentationStyle = UIModalPresentationStyle.OverCurrentContext
 self.presentViewController(navigationController, animated: true, completion: nil)

For swift 4 latest syntax using extension

extension UIViewController {
    func presentOnRoot(`with` viewController : UIViewController){
        let navigationController = UINavigationController(rootViewController: viewController)
        navigationController.modalPresentationStyle = UIModalPresentationStyle.overCurrentContext
        self.present(navigationController, animated: false, completion: nil)
    }
}

How to use

let popup : PopupVC = self.storyboard?.instantiateViewControllerWithIdentifier("PopupVC") as! PopupVC
self.presentOnRoot(with: popup)

After testing most of the switches this worked for me:

xcopy C:\folder1 C:\folder2\folder1 /t /e /i /y

This will copy the folder folder1 into the folder folder2. So the directory tree would look like:

C:
   Folder1
   Folder2
      Folder1

The easiest way is to use python-memcached-stats package, https://github.com/abstatic/python-memcached-stats

The keys() method should get you going.

Example -

from memcached_stats import MemcachedStats
mem = MemcachedStats()

mem.keys()
['key-1',
 'key-2',
 'key-3',
 ... ]

Here is a runnable example using the mentioned indeterminate attribute:

const indeterminates = document.getElementsByClassName('indeterminate');_x000D_
indeterminates['0'].indeterminate  = true;

<form>_x000D_
  <div>_x000D_
    <input type="checkbox" checked="checked" />True_x000D_
  </div>_x000D_
  <div>_x000D_
    <input type="checkbox" />False_x000D_
  </div>_x000D_
  <div>_x000D_
    <input type="checkbox" class="indeterminate" />Indeterminate_x000D_
  </div>_x000D_
</form>

Just run the code snippet to see how it looks like.

There are two string methods for this, find() and index(). The difference between the two is what happens when the search string isn't found. find() returns -1 and index() raises ValueError.

Using find()

>>> myString = 'Position of a character'
>>> myString.find('s')
2
>>> myString.find('x')
-1

Using index()

>>> myString = 'Position of a character'
>>> myString.index('s')
2
>>> myString.index('x')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: substring not found

From the Python manual

string.find(s, sub[, start[, end]])
Return the lowest index in s where the substring sub is found such that sub is wholly contained in s[start:end]. Return -1 on failure. Defaults for start and end and interpretation of negative values is the same as for slices.

And:

string.index(s, sub[, start[, end]])
Like find() but raise ValueError when the substring is not found.

I reverse-engineered and made an open source (re)implementation of UIStoryboard's segues: https://github.com/acoomans/Segway

With that library, you can define segues programmatically (without any storyboard).

Hope it may help.

I don't think you can do this with the standard tools. You can use ipcs -mp to get the process ID of the last process to attach/detach but I'm not aware of how to get all attached processes with ipcs.

With a two-process-attached segment, assuming they both stayed attached, you can possibly figure out from the creator PID cpid and last-attached PID lpid which are the two processes but that won't scale to more than two processes so its usefulness is limited.

The cat /proc/sysvipc/shm method seems similarly limited but I believe there's a way to do it with other parts of the /proc filesystem, as shown below:

When I do a grep on the procfs maps for all processes, I get entries containing lines for the cpid and lpid processes.

For example, I get the following shared memory segment from ipcs -m:

------ Shared Memory Segments --------
key        shmid      owner      perms      bytes      nattch     status      
0x00000000 123456     pax        600        1024       2          dest

and, from ipcs -mp, the cpid is 3956 and the lpid is 9999 for that given shared memory segment (123456).

Then, with the command grep 123456 /proc/*/maps, I see:

/proc/3956/maps: blah blah blah 123456 /SYSV000000 (deleted)
/proc/9999/maps: blah blah blah 123456 /SYSV000000 (deleted)

So there is a way to get the processes that attached to it. I'm pretty certain that the dest status and (deleted) indicator are because the creator has marked the segment for destruction once the final detach occurs, not that it's already been destroyed.

So, by scanning of the /proc/*/maps "files", you should be able to discover which PIDs are currently attached to a given segment.

You need to pass your data in the request body as a raw string rather than FormUrlEncodedContent. One way to do so is to serialize it into a JSON string:

var json = JsonConvert.SerializeObject(data); // or JsonSerializer.Serialize if using System.Text.Json

Now all you need to do is pass the string to the post method.

var stringContent = new StringContent(json, UnicodeEncoding.UTF8, "application/json"); // use MediaTypeNames.Application.Json in Core 3.0+ and Standard 2.1+

var client = new HttpClient();
var response = await client.PostAsync(uri, stringContent);

This is my version of check ping function. May be if well be usefull for someone:

def check_ping(host):
if platform.system().lower() == "windows":
response = os.system("ping -n 1 -w 500 " + host + " > nul")
if response == 0:
return "alive"
else:
return "not alive"
else:
response = os.system("ping -c 1 -W 0.5" + host + "> /dev/null")
if response == 1:
return "alive"
else:
return "not alive"

The Laravel 8 documentation actually answers this issue more succinctly and clearly than any of the answers here:

Routing Namespace Updates

In previous releases of Laravel, the RouteServiceProvider contained a $namespace property. This property's value would automatically be prefixed onto controller route definitions and calls to the action helper / URL::action method. In Laravel 8.x, this property is null by default. This means that no automatic namespace prefixing will be done by Laravel. Therefore, in new Laravel 8.x applications, controller route definitions should be defined using standard PHP callable syntax:

use App\Http\Controllers\UserController;

Route::get('/users', [UserController::class, 'index']);

Calls to the action related methods should use the same callable syntax:

action([UserController::class, 'index']);

return Redirect::action([UserController::class, 'index']);

If you prefer Laravel 7.x style controller route prefixing, you may simply add the $namespace property into your application's RouteServiceProvider.

There's no explanation as to why Taylor Otwell added this maddening gotcha, but I presume he had his reasons.

I thought I could add a method I use in many projects.

- (NSInteger)randomValueBetween:(NSInteger)min and:(NSInteger)max {
    return (NSInteger)(min + arc4random_uniform(max - min + 1));
}

If I end up using it in many files I usually declare a macro as

#define RAND_FROM_TO(min, max) (min + arc4random_uniform(max - min + 1))

E.g.

NSInteger myInteger = RAND_FROM_TO(0, 74) // 0, 1, 2,..., 73, 74

Note: Only for iOS 4.3/OS X v10.7 (Lion) and later

Try this.

To get the data from the UserDefaults.

var defaults = NSUserDefaults.standardUserDefaults()
var dict : NSDictionary = ["key":"value"]
var array1: NSArray = dict.allValues // Create a dictionary and assign that to this array
defaults.setObject(array1, forkey : "MyKey")

var myarray : NSArray = defaults.objectForKey("MyKey") as NSArray
println(myarray)

Yes, take a look at this thread which talks about the differences between platforms.

How to detect right-click event for Mac OS

BUTTON3 is the same across all platforms, being equal to the right mouse button. BUTTON2 is simply ignored if the middle button does not exist.

In HTML5, the easiest, and fastest, way to center your <th>THcontent</th> is to add a colspan like this:

<th colspan="3">Thcontent</th> 

This will work if your table is three columns. So if you have a four-column table, add a colspan of 4, etc.

You can manage the location furthermore in the CSS file while you have put your colspan in HTML like I said.

th { 
    text-align: center; /* Or right or left */
}

Just don't anchor your pattern:

/Test/

The above regex will check for the literal string "Test" being found somewhere within it.

In T-SQL you can:

SELECT [Date]
  FROM [FRIIB].[dbo].[ArchiveAnalog]
  GROUP BY [Date], DATEPART(hh, [Date])

or

by minute use DATEPART(mi, [Date])

or

by 10 minutes use DATEPART(mi, [Date]) / 10 (like Timothy suggested)

Try

import platform
platform.python_version()

Should give you a string like "2.3.1". If this is not exactly waht you want there is a rich set of data available through the "platform" build-in. What you want should be in there somewhere.

You need to return to normal mode and save the commit message with either

<Esc>:wq

or

<Esc>:x

or

<Esc>ZZ

The Esc key returns you from insert mode to normal mode. The :wq, :x or ZZ sequence writes the changes and exits the editor.

Wow, so there are a lot of ways to do this.

Yet another way to do this is to delete the last commit, but keep its changes so that you won't lose your work. You can then do another commit with the corrected message. This would look something like this:

git reset --soft HEAD~1
git commit -m 'New and corrected commit message'

I always do this if I forget to add a file or do a change.

Remember to specify --soft instead of --hard, otherwise you lose that commit entirely.

If the problem domain has some kind of string header concept, this could be modelled as an enum.

switch(GetStringHeader(s))
{
    case StringHeader.ABC: ...
    case StringHeader.QWERTY: ...
    ...
}

StringHeader GetStringHeader(string s)
{
    if (s.StartsWith("ABC")) return StringHeader.ABC;
    ...
}

enum StringHeader { ABC, QWERTY, ... }

Please take this as a "dirty" alternative but this saved my behind many times especially when I was not familiar with the DB project. Sometimes you are trying to search for a string within all SPs and forget that some of the related logic may have been hiding between Functions and Triggers or it can be simply worded differently than you thought.

From your MSSMS you may right click your DB and select Tasks -> Generate Scripts wizard to output all the SPs, Fns and Triggers into a single .sql file.

Make sure to select Triggers too!

Then just use Sublime or Notepad to search for the string you need to find. I know this may be quite inefficient and paranoid approach but it works :)

Well I got this Issue too in my few websites and all i need to do is customize the content fetler for HTML entites. before that more i delete them more i got, so just change you html fiter or parsing function for the page and it worked. Its mainly due to HTML editors in most of CMSs. the way they store parse the data caused this issue (In My case). May this would Help in your case too

Explain only shows how the optimizer thinks the query will execute.

To show the real plan, you will need to run the sql once. Then use the same session run the following:

@yoursql 
select * from table(dbms_xplan.display_cursor()) 

This way can show the real plan used during execution. There are several other ways in showing plan using dbms_xplan. You can Google with term "dbms_xplan".

There is a very simple solution to this unless I have not understood the problem. The following regular expression:

(.*)(>)(.*)

will match the pattern specified in your post.

So, in notepad++ you find (.*)(>)(.*) and replace it with \3.

The regular expressions are basically greedy in the sense that if you specify (.*) it will match the whole line and what you want to do is break it down somehow so that you can extract the string you want to keep. Here, I have done exactly the same and it works fine in Notepad++ and Editplus3.
