You need to bind init before initialization.

$('.slider-for').on('init', function(event, slick){
        $(this).append('<div class="slider-count"><p><span id="current">1</span> von <span id="total">'+slick.slideCount+'</span></p></div>');
    });
    $('.slider-for').slick({
      slidesToShow: 1,
      slidesToScroll: 1,
      arrows: true,
      fade: true
    });
    $('.slider-for')
        .on('afterChange', function(event, slick, currentSlide, nextSlide){
            // finally let's do this after changing slides
            $('.slider-count #current').html(currentSlide+1);
        });

The same problem. Python3.5 and pip 8.0.2 installed from Linux rpm's.

I did not find a primary cause and cannot give a proper answer. It looks like there are multiple possible causes.

However, I hope I can help with sharing my observation and a workaround.

1. pyvenv with --system-site-packages

   • ./bin does not contain pip, pip is available from system site packages
   • packages are installed globally (BUG?)

2. pyvenv without --system-site-packages

   • pip gets installed into ./bin, but it's a different version (from ensurepip)
   • packages are installed within the virtual environment (OK)

Obvious workaround for pyvenv with --system-site-packages:

• create it without the --system-site-packages option
• change include-system-site-packages = false to true in pyvenv.cfg file

I was looking for a different problem and came across this, so I will add my solution to a related problem: comparing two Maps.

    // make a copy of the data
    Map<String,String> a = new HashMap<String,String>(actual);
    Map<String,String> e = new HashMap<String,String>(expected);
    // check *every* expected value
    for(Map.Entry<String, String> val : e.entrySet()){
        // check for presence
        if(!a.containsKey(val.getKey())){
            System.out.println(String.format("Did not find expected value: %s", val.getKey()));
        }
        // check for equality
        else{
            if(0 != a.get(val.getKey()).compareTo(val.getValue())){
                System.out.println(String.format("Value does not match expected: %s", val.getValue()));
            }
            // we have found the item, so remove it 
            // from future consideration. While it 
            // doesn't affect Java Maps, other types of sets
            // may contain duplicates, this will flag those
            // duplicates. 
            a.remove(val.getKey());
        }
    }
    // check to see that we did not receive extra values
    for(Map.Entry<String,String> val : a.entrySet()){
        System.out.println(String.format("Found unexpected value: %s", val.getKey()));
    }

It works on the same principle as the other solutions but also compares not only that values are present, but that they contain the same value. Mostly I've used this in accounting software when comparing data from two sources (Employee and Manager entered values match; Customer and Corporate transactions match; ... etc)

queryForMap is appropriate if you want to get a single row. You are selecting without a where clause, so you probably want to queryForList. The error is probably indicative of the fact that queryForMap wants one row, but you query is retrieving many rows.

Check out the docs. There is a queryForList that takes just sql; the return type is a

List<Map<String,Object>>.

So once you have the results, you can do what you are doing. I would do something like

List results = template.queryForList(sql);

for (Map m : results){
   m.get('userid');
   m.get('username');
} 

I'll let you fill in the details, but I would not iterate over keys in this case. I like to explicit about what I am expecting.

If you have a User object, and you actually want to load User instances, you can use the queryForList that takes sql and a class type

queryForList(String sql, Class<T> elementType)

(wow Spring has changed a lot since I left Javaland.)

Use 'this' keyword to access variable. This worked for me

var  uemail = localStorage.getItem("useremail");

if (typeof this.uemail === "undefined")
{
    alert('undefined');
}
else
{
    alert('defined');
}

I know it's waaay late, but it did take me 2 minutes to write this optimized and improved version of AgileJon's answer:

var key, obj, prop, owns = Object.prototype.hasOwnProperty;

for (key in validation_messages ) {

    if (owns.call(validation_messages, key)) {

        obj = validation_messages[key];

        for (prop in obj ) {

            // using obj.hasOwnProperty might cause you headache if there is
            // obj.hasOwnProperty = function(){return false;}
            // but owns will always work 
            if (owns.call(obj, prop)) {
                console.log(prop, "=", obj[prop]);
            }

        }

    }

}

I would use os.chdir like this:

os.chdir("/path/to/change/to")

By the way, if you need to figure out your current path, use os.getcwd().

I simply used background-image css property on the target background div.
Note background-image only accepts gradient color functions.
So I used linear-gradient adding the same desired overlay color twice (use last rgba value to control color opacity).

Also, found these two useful resources to:

1. Add text (or div with any other content) over the background image: Hero Image
2. Blur background image only, without blurring the div on top: Blurred Background Image

HTML

<div class="header_div">
</div>

<div class="header_text">
  <h1>Header Text</h1>
</div>

CSS

.header_div {
  position: relative;
  text-align: cover;
  min-height: 90vh;
  margin-top: 5vh;
  background-position: center;
  background-repeat: no-repeat;
  background-size: cover;
  width: 100vw;
  background-image: linear-gradient(rgba(38, 32, 96, 0.2), rgba(38, 32, 96, 0.4)), url("images\\header img2.jpg");
  filter: blur(2px);
}

.header_text {
  position: absolute;
  top: 50%;
  right: 50%;
  transform: translate(50%, -50%);
}

It's a magic number used in various places because it also happens to be readable in English, making it stand out. There's a partial list on Wikipedia.

You can delete multiple branches on windows using Git GUI:

1. Go to your Project folder
2. Open Git Gui:
3. Click on 'Branch':
4. Now choose 'Delete':
5. If you want to delete all branches besides the fact they are merged or not, then check 'Always (Do not perform merge checks)'

You can create a DAO method to do this.

@Dao 
interface MyDao {
    @Query("DELETE FROM myTableName")
    public void nukeTable();
}

I added

config.EnableCors(new EnableCorsAttribute(Properties.Settings.Default.Cors, "", ""))

as well as

app.UseCors(CorsOptions.AllowAll);

on the server. This results in two header entries. Just use the latter one and it works.

I've quite often seen it used, sometimes as super_t, when the base is a complex template type (boost::iterator_adaptor does this, for example)

If your JSON is without key you can do it like this:

library[library.length] = {"foregrounds" : foregrounds,"backgrounds" : backgrounds};

So, try this:

var library = {[{
    "title"       : "Gold Rush",
        "foregrounds" : ["Slide 1","Slide 2","Slide 3"],
        "backgrounds" : ["1.jpg","","2.jpg"]
    }, {
    "title"       : California",
        "foregrounds" : ["Slide 1","Slide 2","Slide 3"],
        "backgrounds" : ["3.jpg","4.jpg","5.jpg"]
    }]
}

Then:

library[library.length] = {"title" : "Gold Rush", "foregrounds" : ["Howdy","Slide 2"], "backgrounds" : ["1.jpg",""]};

if(getResult.Key.Equals(default(T)) && getResult.Value.Equals(default(U)))

Be aware that the path under src/main/resources must match the package path of your .class files wishing to access the resource. See my answer here.

I find solution that instead of using ListBox I used ListView.It allows to change list items BackColor.

private void listView1_Refresh()
{
    for (int i = 0; i < listView1.Items.Count; i++)
    {
        listView1.Items[i].BackColor = Color.Red;
        for (int j = 0; j < existingStudents.Count; j++)
        {
            if (listView1.Items[i].ToString().Contains(existingStudents[j]))
            {
                listView1.Items[i].BackColor = Color.Green;
            }
        }
    }
}

Bubble sort with sort direction -

using System;

public class Program
{
    public static void Main(string[] args)
    {
        var input = new[] { 800, 11, 50, 771, 649, 770, 240, 9 };

        BubbleSort(input);

        Array.ForEach(input, Console.WriteLine);

        Console.ReadKey();
    }

    public enum Direction
    {
        Ascending = 0,
        Descending
    }

    public static void BubbleSort(int[] input, Direction direction = Direction.Ascending)
    {
        bool swapped;
        var length = input.Length;

        do
        {
            swapped = false;
            for (var index = 0; index < length - 1; index++)
            {
                var needSwap = direction == Direction.Ascending ? input[index] > input[index + 1] : input[index] < input[index + 1];

                if (needSwap)
                {
                    var temp = input[index];
                    input[index] = input[index + 1];
                    input[index + 1] = temp;
                    swapped = true;
                }
            }
        } while (swapped);
    }
}

Another option is using eval and parse, as in

d = 5
for (i in 1:10){
     eval(parse(text = paste('a', 1:10, ' = d + rnorm(3)', sep='')[i]))
}

As webstrap mentioned in a comment:

It worked if the video start with "v" and it's from youtu.be

The regex contains a little bug \??v?=? this should just be at the watch part, otherwise you would filter a 'v' if the id starts with a 'v'. so this should do the trick

/^.*((youtu.be\/)|(v\/)|(\/u\/\w\/)|(embed\/)|(watch\??v?=?))([^#\&\?]*).*/

Declarations of public functions go in header files, yes, but definitions are absolutely valid in headers as well! You may declare the definition as static (only 1 copy allowed for the entire program) if you are defining things in a header for utility functions that you don't want to have to define again in each c file. I.E. defining an enum and a static function to translate the enum to a string. Then you won't have to rewrite the enum to string translator for each .c file that includes the header. :)

Here is a function that times execution of any piece of PHP code, much like Python's timeit module does: https://gist.github.com/flaviovs/35aab0e85852e548a60a

How to use it:

include('timeit.php');
const SOME_CODE = '
        strlen("foo bar");
';
$t = timeit(SOME_CODE);
print "$t[0] loops; $t[2] per loop\n";

Result:

$ php x.php 
100000 loops; 18.08us per loop

Disclaimer: I am the author of this Gist

EDIT: timeit is now a separate, self-contained project at https://github.com/flaviovs/timeit

Use Collections class API to sort.

Collections.sort(list);

when you open the Jenkins panel it will show available package from their latest version. you can download it via wget command in the server.after download the latest package you should take .war backup file.

Eg-: wget http://updates.jenkins-ci.org/download/war/2.205/jenkins.war

Jenkins war file path for Ubuntu - /usr/share/jenkins/

Jenkins war file path for centos - /usr/lib/jenkins/

after taking backup overwrite the war file and restart the jenkins service.

Ubuntu - service jenkins restart , centos - systemctl restart jenkins.service

You could call:

getContentPane().setBackground(Color.black);

Or add a JPanel to the JFrame your using. Then add your components to the JPanel. This will allow you to call

setBackground(Color.black);

on the JPanel to set the background color.

How about dropping the entire database and then creating it again? This works for me.

DROP DATABASE mydb;
CREATE DATABASE mydb;

try this

$ cmd='mysql AMORE -u root --password="password" -h localhost -e "select host from amoreconfig"'
$ eval $cmd

Vartec's answer with cURL didn't work for me. It did, with a slight improvement due to my specific problem.

e.g.,

When there is a redirect on the server (like when you are trying to save the facebook profile image) you will need following option set:

curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);

The full solution becomes:

$ch = curl_init('http://example.com/image.php');
$fp = fopen('/my/folder/flower.gif', 'wb');
curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_exec($ch);
curl_close($ch);
fclose($fp);

Arguments and parameters are different in that parameters are used to different values in the program and The arguments are passed the same value in the program so they are used in c++. But no difference in c. It is the same for arguments and parameters in c.

My solution was to do a combination of these two resources:

https://gist.github.com/tamoyal/2ea1fcdf99c819b4e07d

and

http://www.gab.lc/articles/migration_postgresql_9-3_to_9-4

The second one helped more then the first one. Also to not, don't follow the steps as is as some are not necessary. Also, if you are not being able to backup the data via postgres console, you can use alternative approach, and backup it with pgAdmin 3 or some other program, like I did in my case.

Also, the link: https://help.ubuntu.com/stable/serverguide/postgresql.html Helped to set the encrypted password and set md5 for authenticating the postgres user.

After all is done, to check the postgres server version run in terminal:

sudo -u postgres psql postgres

After entering the password run in postgres terminal:

SHOW SERVER_VERSION;

It will output something like:

 server_version 
----------------
 9.4.5

For setting and starting postgres I have used command:

> sudo bash # root
> su postgres # postgres

> /etc/init.d/postgresql start
> /etc/init.d/postgresql stop

And then for restoring database from a file:

> psql -f /home/ubuntu_username/Backup_93.sql postgres

Or if doesn't work try with this one:

> pg_restore --verbose --clean --no-acl --no-owner -h localhost -U postgres -d name_of_database ~/your_file.dump

And if you are using Rails do a bundle exec rake db:migrate after pulling the code :)

Try this:

[Authorize]
public ActionResult SomeAction()
{
    var identity = (ClaimsIdentity)User.Identity;
    IEnumerable<Claim> claims = identity.Claims;
    ...
}

Going off of tbradley22's answer, but using .map instead:

var a = ["car", "bike", "scooter"];
a.map(function(entry) {
    var singleObj = {};
    singleObj['type'] = 'vehicle';
    singleObj['value'] = entry;
    return singleObj;
});

I enabled the Failed Request Tracing, and got the following info:

 <EventData>
  <Data Name="ContextId">{00000000-0000-0000-0F00-0080000000FA}</Data>
  <Data Name="ModuleName">WebDAVModule</Data>
  <Data Name="Notification">16</Data>
  <Data Name="HttpStatus">405</Data>
  <Data Name="HttpReason">Method Not Allowed</Data>
  <Data Name="HttpSubStatus">0</Data>
  <Data Name="ErrorCode">0</Data>
  <Data Name="ConfigExceptionInfo"></Data>
 </EventData>

So, I uninstalled the WebDAVModule from my IIS, everything is fine now~

The IIS tracing feature is very helpful.

You could compare DOM elements. Remember that jQuery selectors return arrays which will never be equal in the sense of reference equality.

Assuming:

<div id="a" class="a"></div>

this:

$('div.a')[0] == $('div#a')[0]

returns true.

Note: This question is related to the jQuery form plugin. If you are searching for a pure jQuery solution, start here. There is no overall jQuery solution for all browser. So you have to use a plugin. I am using dropzone.js, which have an easy fallback for older browsers. Which plugin you prefer depends on your needs. There are a lot of good comparing post out there.

From the examples:

jQuery:

$(function() {

    var bar = $('.bar');
    var percent = $('.percent');
    var status = $('#status');

    $('form').ajaxForm({
        beforeSend: function() {
            status.empty();
            var percentVal = '0%';
            bar.width(percentVal);
            percent.html(percentVal);
        },
        uploadProgress: function(event, position, total, percentComplete) {
            var percentVal = percentComplete + '%';
            bar.width(percentVal);
            percent.html(percentVal);
        },
        complete: function(xhr) {
            status.html(xhr.responseText);
        }
    });
}); 

html:

<form action="file-echo2.php" method="post" enctype="multipart/form-data">
    <input type="file" name="myfile"><br>
    <input type="submit" value="Upload File to Server">
</form>

<div class="progress">
    <div class="bar"></div >
    <div class="percent">0%</div >
</div>

<div id="status"></div>

you have to style the progressbar with css...

Responsive Solution

Here is a good solution for responsive design or unknown dimensions in general if you don't need to support IE8 and lower.

.centered-axis-x {
    position: absolute;
    left: 50%;
    transform: translate(-50%, 0);
}

.outer {
    position: relative; /* or absolute */
    
    /* unnecessary styling properties */
    margin: 5%;
    width: 80%;
    height: 500px;
    border: 1px solid red;
}

.inner {
    position: absolute;
    left: 50%;
    top: 50%;
    transform: translate(-50%, -50%);
    
    /* unnecessary styling properties */
    max-width: 50%;
    text-align: center;
    border: 1px solid blue;
}

<div class="outer">
    <div class="inner">I'm always centered<br/>doesn't matter how much text, height or width i have.<br/>The dimensions or my parent are irrelevant as well</div>
</div>

Here is a JS Fiddle

The clue is, that left: 50% is relative to the parent while the translate transform is relative to the elements width/height.

This way you have a perfectly centered element, with a flexible width on both child and parent. Bonus: this works even if the child is bigger than the parent.

You can also center it vertically with this (and again, width and height of parent and child can be totally flexible (and/or unknown)):

.centered-axis-xy {
    position: absolute;
    left: 50%;
    top: 50%;
    transform: translate(-50%,-50%);
}

Keep in mind that you might need transform vendor prefixed as well. For example -webkit-transform: translate(-50%,-50%);

under Cryptography Application Block.

Don't know if you will get your answer, but it's worth a try.

Edit after Comment.

Ok then check this code.

using System.Security.Cryptography;


public static string DecryptEncryptedData(stringBase64EncryptedData, stringPathToPrivateKeyFile) { 
    X509Certificate2 myCertificate; 
    try{ 
        myCertificate = new X509Certificate2(PathToPrivateKeyFile); 
    } catch{ 
        throw new CryptographicException("Unable to open key file."); 
    } 

    RSACryptoServiceProvider rsaObj; 
    if(myCertificate.HasPrivateKey) { 
         rsaObj = (RSACryptoServiceProvider)myCertificate.PrivateKey; 
    } else 
        throw new CryptographicException("Private key not contained within certificate."); 

    if(rsaObj == null) 
        return String.Empty; 

    byte[] decryptedBytes; 
    try{ 
        decryptedBytes = rsaObj.Decrypt(Convert.FromBase64String(Base64EncryptedData), false); 
    } catch { 
        throw new CryptographicException("Unable to decrypt data."); 
    } 

    //    Check to make sure we decrpyted the string 
   if(decryptedBytes.Length == 0) 
        return String.Empty; 
    else 
        return System.Text.Encoding.UTF8.GetString(decryptedBytes); 
} 

Relaxing your requirement to work on IE6 and legacy browsers you can use ::before and display: inline-block

div
{
  display: inline-block;
  position: relative;    
}
div::before
{
  content: "";
  display: block;
  position: absolute;
  z-index: -1;
  width: 100%;
  height: 100%;
  background:red;
  opacity: .2;
}

It will work on any modern browser

Instead of using array you can use the ArrayList directly and can use the contains method to check the value which u have passes with the ArrayList.

Wikipedia sums this up well:

On modern computer systems, localhost as a hostname translates to an IPv4 address in the 127.0.0.0/8 (loopback) net block, usually 127.0.0.1, or ::1 in IPv6.

The only difference is that it would be looking up in the DNS for the system what localhost resolves to. This lookup is really, really quick. For instance, to get to stackoverflow.com you typed in that to the address bar (or used a bookmarklet that pointed here). Either way, you got here through a hostname. localhost provides a similar functionality.

This command will get you the last commit message:

git log -1 --oneline --format=%s | sed 's/^.*: //'

outputs something similar to:

Create FUNDING.yml

You can change the -1 to any negative number to increase the range of commit messages retrieved

The question has already been answered, but I thought I'd add an answer with more precise terminology and references to the C++ standard.

Two things are going on here, array parameters being adjusted to pointer parameters, and array arguments being converted to pointer arguments. These are two quite different mechanisms, the first is an adjustment to the actual type of the parameter, whereas the other is a standard conversion which introduces a temporary pointer to the first element.

Adjustments to your function declaration:

dcl.fct#5:

After determining the type of each parameter, any parameter of type “array of T” (...) is adjusted to be “pointer to T”.

So int arg[] is adjusted to be int* arg.

Conversion of your function argument:

conv.array#1

An lvalue or rvalue of type “array of N T” or “array of unknown bound of T” can be converted to a prvalue of type “pointer to T”. The temporary materialization conversion is applied. The result is a pointer to the first element of the array.

So in printarray(firstarray, 3);, the lvalue firstarray of type "array of 3 int" is converted to a prvalue (temporary) of type "pointer to int", pointing to the first element.

For Access (or any SQL language)

1. Create one table that has 2 fields, we'll call this table tempRunDates:
   --Fields fromDate and toDate
   --Then insert only 1 record, that has the start date and the end date.

2. Create another table: Time_Day_Ref
   --Import a list of dates (make list in excel is easy) into this table.
   --The field name in my case is Greg_Dt, for Gregorian Date
   --I made my list from jan 1 2009 through jan 1 2020.

3. Run the query:

   SELECT Time_Day_Ref.GREG_DT
   FROM tempRunDates, Time_Day_Ref
   WHERE Time_Day_Ref.greg_dt>=tempRunDates.fromDate And greg_dt<=tempRunDates.toDate;
   

Easy!

Take a look at the ExpandoObject.

For example:

dynamic person = new ExpandoObject();
person.Name = "Mr bar";
person.Sex = "No Thanks";
person.Age = 123;

According to HTML5 drafts, the checked attribute is a “boolean attribute”, and “The presence of a boolean attribute on an element represents the true value, and the absence of the attribute represents the false value.” It is the name of the attribute that matters, and suffices. Thus, to make a checkbox initially checked, you use

<input type=checkbox checked>

By default, in the absence of the checked attribute, a checkbox is initially unchecked:

<input type=checkbox>

Keeping things this way keeps them simple, but if you need to conform to XML syntax (i.e. to use HTML5 in XHTML linearization), you cannot use an attribute name alone. Then the allowed (as per HTML5 drafts) values are the empty string and the string checked, case insensitively. Example:

<input type="checkbox" checked="checked" />

It is cumbersome to interoperate socket.io and connect sessions support. The problem is not because socket.io "hijacks" request somehow, but because certain socket.io transports (I think flashsockets) don't support cookies. I could be wrong with cookies, but my approach is the following:

1. Implement a separate session store for socket.io that stores data in the same format as connect-redis
2. Make connect session cookie not http-only so it's accessible from client JS
3. Upon a socket.io connection, send session cookie over socket.io from browser to server
4. Store the session id in a socket.io connection, and use it to access session data from redis.

Nested class: class inside class

Types:

1. Static nested class
2. Non-static nested class [Inner class]

Difference:

Non-static nested class [Inner class]

In non-static nested class object of inner class exist within object of outer class. So that data member of outer class is accessible to inner class. So to create object of inner class we must create object of outer class first.

outerclass outerobject=new outerobject();
outerclass.innerclass innerobjcet=outerobject.new innerclass(); 

Static nested class

In static nested class object of inner class don't need object of outer class, because the word "static" indicate no need to create object.

class outerclass A {
    static class nestedclass B {
        static int x = 10;
    }
}

If you want to access x, then write the following inside method

  outerclass.nestedclass.x;  i.e. System.out.prinltn( outerclass.nestedclass.x);

When you say

enum {RANDOM, IMMEDIATE, SEARCH} strategy;

you create a single instance variable, called 'strategy' of a nameless enum. This is not a very useful thing to do - you need a typedef:

typedef enum {RANDOM, IMMEDIATE, SEARCH} StrategyType; 
StrategyType strategy = IMMEDIATE;

Instructions:

1. Click on the Terminal icon in the desktop panel to open a terminal window and access the command prompt.
2. Type the command which java to find the path to the Java executable file.
3. Type the command su - to become the root user.
4. Type the command vi /root/.bash_profile to open the system bash_profile file in the Vi text editor. You can replace vi with your preferred text editor.
5. Type export JAVA_HOME=/usr/local/java/ at the bottom of the file. Replace /usr/local/java with the location found in step two.
6. Save and close the bash_profile file.
7. Type the command exit to close the root session.
8. Log out of the system and log back in.
9. Type the command echo $JAVA_HOME to ensure that the path was set correctly.

The wiki is talking from a forked repo point of view. You have access to pull and push from origin, which will be your fork of the main diaspora repo. To pull in changes from this main repo, you add a remote, "upstream" in your local repo, pointing to this original and pull from it.

So "origin" is a clone of your fork repo, from which you push and pull. "Upstream" is a name for the main repo, from where you pull and keep a clone of your fork updated, but you don't have push access to it.

This will return an MD5 hash for a file on a remote computer:

Invoke-Command -ComputerName RemoteComputerName -ScriptBlock {
    $fullPath = Resolve-Path 'c:\Program Files\Internet Explorer\iexplore.exe'
    $md5 = new-object -TypeName System.Security.Cryptography.MD5CryptoServiceProvider
    $file = [System.IO.File]::OpenRead($fullPath)
    $hash = [System.BitConverter]::ToString($md5.ComputeHash($file))
    $hash -replace "-", ""
    $file.Dispose()
}

To generate a YYYY-MM-DD hh:mm:ss (24-hour) timestamp I use:

SET CURRENTTIME=%TIME%
IF "%CURRENTTIME:~0,1%"==" " (SET CURRENTTIME=0%CURRENTTIME:~1%)
FOR /F "tokens=2-4 delims=/ " %%A IN ('DATE /T') DO (SET TIMESTAMP=%%C-%%A-%%B %CURRENTTIME%)

Below is another way by which we can JSON data with JSON.stringify() function

var Utils = {};
Utils.MyClass1 = function (id, member) {
    this.id = id;
    this.member = member;
}
var myobject = { MyClass1: new Utils.MyClass1("5678999", "text") };
alert(JSON.stringify(myobject));

For recent SQL:

select * from v$sql

For history:

select * from dba_hist_sqltext

As other answers mentioned you can use ajaxStop() to wait until all ajax request are completed.

$(document).ajaxStop(function() {
     // This function will be triggered every time any ajax request is requested and completed
});

If you want do it for an specific ajax() request the best you can do is use complete() method inside the certain ajax request:

$.ajax({
    type: "POST",
    url: "someUrl",
    success: function(data) {
        // This function will be triggered when ajax returns a 200 status code (success)
    },
    complete: function() {
        // This function will be triggered always, when ajax request is completed, even it fails/returns other status code
    },
    error: function() {
        // This will be triggered when ajax request fail.
    }
});

But, If you need to wait only for a few and certain ajax request to be done? Use the wonderful javascript promises to wait until the these ajax you want to wait are done. I made a shortly, easy and readable example to show you how does promises works with ajax.
Please take a look to the next example. I used setTimeout to clarify the example.

See the doc : it will close all running tasks using the executable file something.exe, more or less like linux' killall

You can use netstat this way for much faster results:

On Linux:

netstat -lnt | awk '$6 == "LISTEN" && $4 ~ /\.445$/'

On Mac:

netstat -anp tcp | awk '$6 == "LISTEN" && $4 ~ /\.445$/'

This will output a list of processes listening on the port (445 in this example) or it will output nothing if the port is free.

In my nginx install I found I had to go to:

/opt/nginx/cache

and

sudo rm -rf *

in that directory. If you know the path to your nginx install and can find the cache directory the same may work for you. Be very careful with the rm -rf command, if you are in the wrong directory you could delete your entire hard drive.

The URL approach will only work for small HTML fragements. The more solid approach is to generate an object URL from a blob and use it as a source of the dynamic iframe.

const html = '<html>...</html>';
const iframe = document.createElement('iframe');
const blob = new Blob([html], {type: 'text/html'});
iframe.src = window.URL.createObjectURL(blob);
document.body.appendChild(iframe);

You are doing mistake in "configuration_page.jsp" file. here in this file , function loadXMLDoc() 's line number 2 should be like this:

var config=document.getElementsByName('configselect').value;

because you have declared only the name attribute in your <select> tag. So you should get this element by name.

After correcting this, it will run without any JavaScript error

You can do this all in the File.open block:

Dir.chdir 'C:/Users/name/Music'
music = Dir['C:/Users/name/Music/*.{mp3, MP3}']
puts 'what would you like to call the playlist?'
playlist_name = gets.chomp + '.m3u'

File.open playlist_name, 'w' do |f|
  music.each do |z|
    f.puts z
  end
end

You can use the CSS property "background-color: transparent;", or use apha on rgba color representation. Example: "background-color: rgba(216,240,218,0);"

The apha is the last value. It is a decimal number that goes from 0 (totally transparent) to 1 (totally visible).

Actually there is a way to do this. It has limitation (one), but is 100% standard, not deprecated (like xmp), and works.

And it's trivial. Here it is:

<div id="mydoc-src" style="display: none;">
LlNnlljn77fggggkk77csJJK8bbJBKJBkjjjjbbbJJLJLLJo
<!--
YOUR CODE HERE.
    <script src="WidgetsLib/all.js"></script>
    ^^ This is a text, no side effects trying to load it.
-->
LlNnlljn77fggggkk77csJJK8bbJBKJBkjjjjbbbJJLJLLJo
</div>

Please let me explain. First of all, ordinary HTML comment does the job, to prevent whole block be interpreted. You can easily add in it any tags, all of them will be ignored. Ignored from interpretation, but still available via innerHTML! So what is left, is to get the contents, and filter the preceding and trailing comment tokens.

Except (remember - the limitation) you can't put there HTML comments inside, since (at least in my Chrome) nesting of them is not supported, and very first '-->' will end the show.

Well, it is a nasty little limitation, but in certain cases it's not a problem at all, if your text is free of HTML comments. And, it's easier to escape one construct, then a whole bunch of them.

Now, what is that weird LlNnlljn77fggggkk77csJJK8bbJBKJBkjjjjbbbJJLJLLJo string? It's a random string, like a hash, unlikely to be used in the block, and used for? Here's the context, why I have used it. In my case, I took the contents of one DIV, then processed it with Showdown markdown, and then the output assigned into another div. The idea was, to write markdown inline in the HTML file, and just open in a browser and it would transform on the load on-the-fly. So, in my case, <!-- became transformed to <p><!--</p>, the comment properly escaped. It worked, but polluted the screen. So, to easily remove it with regex, the random string was used. Here's the code:

    var converter = new showdown.Converter();
    converter.setOption('simplifiedAutoLink', true);
    converter.setOption('tables', true);
    converter.setOption('tasklists', true);
    var src = document.getElementById("mydoc-src");
    var res = document.getElementById("mydoc-res");
    res.innerHTML = converter.makeHtml(src.innerHTML)
            .replace(/<p>.{0,10}LlNnlljn77fggggkk77csJJK8bbJBKJBkjjjjbbbJJLJLLJo.{0,10}<\/p>/g, "");
    src.innerHTML = '';

And it works.

If somebody is interested, this article is written using this technique. Feel free to download, and look inside the HTML file.

It depends what you are using it for. Is it user input? Then use <textarea>, and escape everything. In my case, and probably it's your case too, I simply used comments, and it does the job.

If you don't use markdown, and just want to get it as is from a tag, then it's even simpler:

<div id="mydoc-src" style="display: none;">
<!--
YOUR CODE HERE.
    <script src="WidgetsLib/all.js"></script>
    ^^ This is a text, no side effects trying to load it.
-->
</div>

and JavaScript code to get it:

    var src = document.getElementById("mydoc-src");
    var YOUR_CODE = src.innerHTML.replace(/(<!--|-->)/g, "");

Use a media query. Example: This is something im using the original size is 1.0vw but when it hits 1000 the letter gets too small so I scale it up

@media(max-width:600px){
    body,input,textarea{
         font-size:2.0vw !important;
    }
}

This site I m working on is not responsive for >500px but you might need more. The pro,benefit for this solution is you keep font size scaling without having super mini letters and you can keep it js free.

if you want to pick file from Bin folder of the application then you can try following and don't forget to do exception handling.

string content = File.ReadAllText(Path.Combine(System.IO.Directory.GetCurrentDirectory(), @"FilesFolder\Sample.txt"));

print(sys.executable)
print(sys.version)
print(sys.version_info)

This is needed to have multiple IPython kernels at the same time. --display-name DISPLAY_NAME Specify the display name for the kernelspec. This is helpful when you have multiple IPython kernels. --profile PROFILE Specify an IPython profile to load. This can be used to create custom versions of the kernel. --prefix PREFIX Specify an install prefix for the kernelspec. This is needed to install into a non-default location, such as a conda/virtual-env. --sys-prefix Install to Python's sys.prefix. Shorthand for --prefix='/Users/bussonniermatthias/anaconda'. For use in conda/virtual-envs.

I made some big lists. One is a list and one is a numpy array.

import numpy as np
import random
arrayv=np.random.randint(0,10,(100000000,1))
listv=[]
for i in range(0,100000000):
    listv.append(random.randint(0,9))

Using jupyter notebook's %%time function I can compare the speed of various things.

2 seconds:

%%time
listv.index(max(listv))

54.6 seconds:

%%time
listv.index(max(arrayv))

6.71 seconds:

%%time
np.argmax(listv)

103 ms:

%%time
np.argmax(arrayv)

numpy's arrays are crazy fast.

Check your Pattern (DD-MMM-YYYY) and the input for the parse("29-11-2018") method. Input to the parse method should follow : DD-MMM-YYYY i,e. 21-AUG-2019

String pattern = "DD-MMM-YYYY";
SimpleDateFormat simpleDateFormat = new SimpleDateFormat(pattern);

    try {
        startDate = simpleDateFormat.parse("29-11-2018");// here no pattern match 
        endDate = simpleDateFormat.parse("28-AUG-2019");// Ok 
    } catch (ParseException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();

Let's get definitive about AngularJS and SEO

Google, Yahoo, Bing, and other search engines crawl the web in traditional ways using traditional crawlers. They run robots that crawl the HTML on web pages, collecting information along the way. They keep interesting words and look for other links to other pages (these links, the amount of them and the number of them come into play with SEO).

So why don't search engines deal with javascript sites?

The answer has to do with the fact that the search engine robots work through headless browsers and they most often do not have a javascript rendering engine to render the javascript of a page. This works for most pages as most static pages don't care about JavaScript rendering their page, as their content is already available.

What can be done about it?

Luckily, crawlers of the larger sites have started to implement a mechanism that allows us to make our JavaScript sites crawlable, but it requires us to implement a change to our site.

If we change our hashPrefix to be #! instead of simply #, then modern search engines will change the request to use _escaped_fragment_ instead of #!. (With HTML5 mode, i.e. where we have links without the hash prefix, we can implement this same feature by looking at the User Agent header in our backend).

That is to say, instead of a request from a normal browser that looks like:

http://www.ng-newsletter.com/#!/signup/page

A search engine will search the page with:

http://www.ng-newsletter.com/?_escaped_fragment_=/signup/page

We can set the hash prefix of our Angular apps using a built-in method from ngRoute:

angular.module('myApp', [])
.config(['$location', function($location) {
  $location.hashPrefix('!');
}]);

And, if we're using html5Mode, we will need to implement this using the meta tag:

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

Reminder, we can set the html5Mode() with the $location service:

angular.module('myApp', [])
.config(['$location', 
function($location) {
  $location.html5Mode(true);
}]);

Handling the search engine

We have a lot of opportunities to determine how we'll deal with actually delivering content to search engines as static HTML. We can host a backend ourselves, we can use a service to host a back-end for us, we can use a proxy to deliver the content, etc. Let's look at a few options:

Self-hosted

We can write a service to handle dealing with crawling our own site using a headless browser, like phantomjs or zombiejs, taking a snapshot of the page with rendered data and storing it as HTML. Whenever we see the query string ?_escaped_fragment_ in a search request, we can deliver the static HTML snapshot we took of the page instead of the pre-rendered page through only JS. This requires us to have a backend that delivers our pages with conditional logic in the middle. We can use something like prerender.io's backend as a starting point to run this ourselves. Of course, we still need to handle the proxying and the snippet handling, but it's a good start.

With a paid service

The easiest and the fastest way to get content into search engine is to use a service Brombone, seo.js, seo4ajax, and prerender.io are good examples of these that will host the above content rendering for you. This is a good option for the times when we don't want to deal with running a server/proxy. Also, it's usually super quick.

For more information about Angular and SEO, we wrote an extensive tutorial on it at http://www.ng-newsletter.com/posts/serious-angular-seo.html and we detailed it even more in our book ng-book: The Complete Book on AngularJS. Check it out at ng-book.com.

This is what I have been using successfully:

...
<div class="custom-file">
    <input type="file" class="custom-file-input image-gallery" id="image-gallery" name="image-gallery[]" multiple accept="image/*">
   <label class="custom-file-label" for="image-gallery">Upload Image(s)</label>
</div>
...

It is always a good idea to check for the actual file type on the server-side as well.

It had the same problem, all I did was give read-only permissions for all users and all items included in the following folders:

/Applications/XAMPP/xamppfiles/etc
/Applications/XAMPP/xamppfiles/sbin

There are two kinds of cell reference, and it's really valuable to understand them well.

One is relative reference, which is what you get when you just type the cell: A5. This reference will be adjusted when you paste or fill the formula into other cells.

The other is absolute reference, and you get this by adding dollar signs to the cell reference: $A$5. This cell reference will not change when pasted or filled.

A cool but rarely used feature is that row and column within a single cell reference may be independent: $A5 and A$5. This comes in handy for producing things like multiplication tables from a single formula.

Then if you check the "Regular expression" button and you want in your replacement to use a part of your matching pattern, you must use "capture groups" (read more on google). For example, let's say that you want to match each of the following lines

value="4"
value="403"
value="200"
value="201"
value="116"
value="15"

using the .*"\d+" pattern and want to keep only the number. You can then use a capture group in your matching pattern, using parentheses ( and ), like that: .*"(\d+)". So now in your replacement you can simply write $1, where $1 references to the value of the 1st capturing group and will return the number for each successful match. If you had two capture groups, for example (.*)="(\d+)", $1 will return the string value and $2 will return the number.

So by using:

Find: .*"(\d+)"

Replace: $1

It will return you

4
403
200
201
116
15

Please note that there many alternate and better ways of matching the aforementioned pattern. For example the pattern value="([0-9]+)" would be better, since it is more specific and you will be sure that it will match only these lines. It's even possible of making the replacement without the use of capture groups, but this is a slightly more advanced topic, so I'll leave it for now :)

You need to install the provisioning profile (drag and drop it into iTunes). Then drag and drop the .ipa. Ensure you device is set to sync apps, and try again.

Unless you accidentally read in the whole input file instead of reading it line by line, then your primary limitation will be disk speed. You may want to try starting with a file containing 100 lines and write it to 100 different files one line in each and make the triggering mechanism work on the number of lines written to the current file. That program will be easily scalable to your situation.

The latest Spring + JPA versions solve this problem fundamentally. You can learn more how to use Spring and JPA togather in a separate thread

Add any other allowable non-alphanumeric characters to the middle brackets to allow them to be parsed as well.

center-block is bad idea as it covers a portion on your screen and you cannot click on your fields or buttons. col-md-offset-? is better option.

Use col-md-offset-3 is better option if class is col-sm-6. Just change the number to center your block.

-Open Keychain - Check all certificates by selecting it. - Check status if it is valid or not. -If certificate is not valid then right click on it and delete that certificate

First, there is no such thing as a JSON object. JSON is a string format that can be used as a representation of a Javascript object literal.

Since JSON is a string, Javascript will treat it like a string, and not like an object (or array or whatever you are trying to use it as.)

Here is a good JSON reference to clarify this difference:

http://benalman.com/news/2010/03/theres-no-such-thing-as-a-json/

So if you need accomplish the task mentioned in your question, you must convert the JSON string to an object or deal with it as a string, and not as a JSON array. There are several libraries to accomplish this. Look at http://www.json.org/js.html for a reference.

Here's an example using Angular 2+

For example, if you wanted to close a Modal Component if the user clicks outside of it:

// Close the modal if the document is clicked.

@HostListener('document:click', ['$event'])
public onDocumentClick(event: MouseEvent): void {
  this.closeModal();
}

// Don't close the modal if the modal itself is clicked.

@HostListener('click', ['$event'])
public onClick(event: MouseEvent): void {
  event.stopPropagation();
}

An INT will always be 4 bytes no matter what length is specified.

• TINYINT = 1 byte (8 bit)
• SMALLINT = 2 bytes (16 bit)
• MEDIUMINT = 3 bytes (24 bit)
• INT = 4 bytes (32 bit)
• BIGINT = 8 bytes (64 bit).

The length just specifies how many characters to pad when selecting data with the mysql command line client. 12345 stored as int(3) will still show as 12345, but if it was stored as int(10) it would still display as 12345, but you would have the option to pad the first five digits. For example, if you added ZEROFILL it would display as 0000012345.

... and the maximum value will be 2147483647 (Signed) or 4294967295 (Unsigned)

Another simple solution is to define your onClickListener, in the getView(..) method, of your ListAdapter.

public View getView(final int position, View convertView, ViewGroup parent){
    //initialise your view
    ...
    View row = context.getLayoutInflater().inflate(R.layout.list_item, null);
    ...

    //define your listener on inner items

    //define your global listener
    row.setOnClickListener(new OnClickListener(){
        public void onClick(View v) {
            doSomethingWithViewAndPosition(v,position);
        }
    });

    return row;

That way your row are clickable, and your inner view too :)

How about something like:

struct foo bar;
update(init_id(42, init_dont_care(&bar)));

with:

struct foo* init_dont_care(struct foo* bar) {
  bar->id = dont_care;
  bar->route = dont_care;
  bar->backup_route = dont_care;
  bar->current_route = dont_care;
  return bar;
}

and:

struct foo* init_id(int id, struct foo* bar) {
  bar->id = id;
  return bar;
}

and correspondingly:

struct foo* init_route(int route, struct foo* bar);
struct foo* init_backup_route(int backup_route, struct foo* bar);
struct foo* init_current_route(int current_route, struct foo* bar);

In C++, a similar pattern has a name which I don't remember just now.

EDIT: It's called the Named Parameter Idiom.

I think what you want to do is add a new item to your list, so you have change the line newinv=inventory+str(add) with this one:

newinv = inventory.append(add)

What you are doing now is trying to concatenate a list with a string which is an invalid operation in Python.

However I think what you want is to add and delete items from a list, in that case your if/else block should be:

if selection=="use":
    print(inventory)
    remove=input("What do you want to use? ")
    inventory.remove(remove)
    print(inventory)

elif selection=="pickup":
    print(inventory)
    add=input("What do you want to pickup? ")
    inventory.append(add)
    print(inventory)

You don't need to build a new inventory list every time you add a new item.

To copy all from Local Location to Remote Location (Upload)

To copy all from Remote Location to Local Location (Download)

scp -r username@hostname:/path/from/destination /path/to/destination

Custom Port where xxxx is custom port number

 scp -r -P xxxx username@hostname:/path/from/destination /path/to/destination

Copy on current directory from Remote to Local

scp -r username@hostname:/path/from/file .

Help:

1. -r Recursively copy all directories and files
2. Always use full location from /, Get full location by pwd
3. scp will replace all existing files
4. hostname will be hostname or IP address
5. if custom port is needed (besides port 22) use -P portnumber
6. . (dot) - it means current working directory, So download/copy from server and paste here only.

Note: Sometimes the custom port will not work due to the port not being allowed in the firewall, so make sure that custom port is allowed in the firewall for incoming and outgoing connection

The way I accomplish this is with a timer.

Run a server timer, have it check the Hour/Minute every 60 seconds.

If it's the right Hour/Minute, then run your process.

I actually have this abstracted out into a base class I call OnceADayRunner.

Let me clean up the code a bit and I'll post it here.

    private void OnceADayRunnerTimer_Elapsed(object sender, ElapsedEventArgs e)
    {
        using (NDC.Push(GetType().Name))
        {
            try
            {
                log.DebugFormat("Checking if it's time to process at: {0}", e.SignalTime);
                log.DebugFormat("IsTestMode: {0}", IsTestMode);

                if ((e.SignalTime.Minute == MinuteToCheck && e.SignalTime.Hour == HourToCheck) || IsTestMode)
                {
                    log.InfoFormat("Processing at: Hour = {0} - Minute = {1}", e.SignalTime.Hour, e.SignalTime.Minute);
                    OnceADayTimer.Enabled = false;
                    OnceADayMethod();
                    OnceADayTimer.Enabled = true;

                    IsTestMode = false;
                }
                else
                {
                    log.DebugFormat("Not correct time at: Hour = {0} - Minute = {1}", e.SignalTime.Hour, e.SignalTime.Minute);
                }
            }
            catch (Exception ex)
            {
                OnceADayTimer.Enabled = true;
                log.Error(ex.ToString());
            }

            OnceADayTimer.Start();
        }
    }

The beef of the method is in the e.SignalTime.Minute/Hour check.

There are hooks in there for testing, etc. but this is what your elapsed timer could look like to make it all work.

When you'll play enough with LocalBroadcastReceiver I'll suggest you to give Green Robot's EventBus a try - you will definitely realize the difference and usefulness of it compared to LBR. Less code, customizable about receiver's thread (UI/Bg), checking receivers availability, sticky events, events could be used as data delivery etc.

Firstly, you need to be aware that UTC isn't a format, it's a time zone, effectively. So "converting from ISO8601 to UTC" doesn't really make sense as a concept.

However, here's a sample program using Joda Time which parses the text into a DateTime and then formats it. I've guessed at a format you may want to use - you haven't really provided enough information about what you're trying to do to say more than that. You may also want to consider time zones... do you want to display the local time at the specified instant? If so, you'll need to work out the user's time zone and convert appropriately.

import org.joda.time.*;
import org.joda.time.format.*;

public class Test {
    public static void main(String[] args) {
        String text = "2011-03-10T11:54:30.207Z";
        DateTimeFormatter parser = ISODateTimeFormat.dateTime();
        DateTime dt = parser.parseDateTime(text);

        DateTimeFormatter formatter = DateTimeFormat.mediumDateTime();
        System.out.println(formatter.print(dt));
    }
}

to indent a ul dropdown menu, use

/* Main Level */
ul{
  margin-left:10px;
}

/* Second Level */
ul ul{
  margin-left:15px;
}

/* Third Level */
ul ul ul{
  margin-left:20px;
}

/* and so on... */

You can indent the lis and (if applicable) the as (or whatever content elements you have) as well , each with differing effects. You could also use padding-left instead of margin-left, again depending on the effect you want.

Update

By default, many browsers use padding-left to set the initial indentation. If you want to get rid of that, set padding-left: 0px;

Still, both margin-left and padding-left settings impact the indentation of lists in different ways. Specifically: margin-left impacts the indentation on the outside of the element's border, whereas padding-left affects the spacing on the inside of the element's border. (Learn more about the CSS box model here)

Setting padding-left: 0; leaves the li's bullet icons hanging over the edge of the element's border (at least in Chrome), which may or may not be what you want.

Examples of padding-left vs margin-left and how they can work together on ul: https://jsfiddle.net/daCrosby/bb7kj8cr/1/

Here's an example using FileReader:

function readSingleFile(e) {
  var file = e.target.files[0];
  if (!file) {
    return;
  }
  var reader = new FileReader();
  reader.onload = function(e) {
    var contents = e.target.result;
    displayContents(contents);
  };
  reader.readAsText(file);
}

function displayContents(contents) {
  var element = document.getElementById('file-content');
  element.textContent = contents;
}

document.getElementById('file-input')
  .addEventListener('change', readSingleFile, false);

<input type="file" id="file-input" />

If you are verifying if a lock is applied on a table or not, try the below query.

SELECT resource_type, resource_associated_entity_id,
    request_status, request_mode,request_session_id,
    resource_description, o.object_id, o.name, o.type_desc

You can add anchor tags. I use this on my site so that I can track with Google Analytics what people are visiting on the page.

I just add an anchor tag and then the part of the page I want to track:

var trackCode = "/#" + urlencode($("myDiv").text());
window.location.href = "http://www.piano-chords.net" + trackCode;
pageTracker._trackPageview(trackCode);

Since the last update of the xmlhttprequest module was around 2 years ago, in some cases it does not work as expected.

So instead, you can use the xhr2 module. In other words:

var XMLHttpRequest = require("xmlhttprequest").XMLHttpRequest;
var xhr = new XMLHttpRequest();

becomes:

var XMLHttpRequest = require('xhr2');
var xhr = new XMLHttpRequest();

But ... of course, there are more popular modules like Axios, because -for example- uses promises:

// Make a request for a user with a given ID
axios.get('/user?ID=12345').then(function (response) {
    console.log(response);
}).catch(function (error) {
    console.log(error);
});

is there a smarter way to do this in Python

This hasn't been mentioned, so I'll go ahead - there is a merge stdlib function in the heapq module of python 2.6+. If all you're looking to do is getting things done, this might be a better idea. Of course, if you want to implement your own, the merge of merge-sort is the way to go.

>>> list1 = [1, 5, 8, 10, 50]
>>> list2 = [3, 4, 29, 41, 45, 49]
>>> from heapq import merge
>>> list(merge(list1, list2))
[1, 3, 4, 5, 8, 10, 29, 41, 45, 49, 50]

Here's the documentation.

You can give the Open Hardware Monitor a go, although it lacks support for the latest processors.

internal sealed class CpuTemperatureReader : IDisposable

        _computer = new Computer { CPUEnabled = true };
        _computer.Open();
    }

    public IReadOnlyDictionary<string, float> GetTemperaturesInCelsius()
    {
        var coreAndTemperature = new Dictionary<string, float>();

        foreach (var hardware in _computer.Hardware)
        {
            hardware.Update(); //use hardware.Name to get CPU model
            foreach (var sensor in hardware.Sensors)
            {
                if (sensor.SensorType == SensorType.Temperature && sensor.Value.HasValue)
                    coreAndTemperature.Add(sensor.Name, sensor.Value.Value);
            }
        }

        return coreAndTemperature;
    }

    public void Dispose()
    {
        try
        {
            _computer.Close();
        }
        catch (Exception)
        {
            //ignore closing errors
        }
    }
}

You can use method getDate():

    inline: true,
    onSelect: function(dateText, inst) { 
        var date = $(this).datepicker('getDate'),
            day  = date.getDate(),  
            month = date.getMonth() + 1,              
            year =  date.getFullYear();
        alert(day + '-' + month + '-' + year);
    }
});

Had troubles as well. On Linux I used Ctrl+X (and Y to confirm) and then I was back on the shell ready to pull/push.

On Windows GIT Bash Ctrl+X would do nothing and found out it works quite like vi/vim. Press i to enter inline insert mode. Type the description at the very top, press esc to exit insert mode, then type :x! (now the cursor is at the bottom) and hit enter to save and exit.

If typing :q! instead, will exit the editor without saving (and commit will be aborted)

I had faced similar issue, behind corporate firewall. Did the following, and able to clone repository using git shell from my system running Windows 7 SP1.

1. Set 'all_proxy' environment variable for your user. Required by curl.

   export all_proxy=http://DOMAIN\proxyuser:[email protected]:8080
   

2. Set 'https_proxy' environment variable for your user. Required by curl.

   export https_proxy=http://DOMAIN\proxyuser:[email protected]:8080
   

3. I am not sure if this has any impact. But I did this and it worked:

   git config --global http.sslverify false
   

4. Use https:// for cloning

   git clone https://github.com/project/project.git
   

Note-1: Do not use http://. Using that can give the below error. It can be resolved by using https://.

 error: RPC failed; result=56, HTTP code = 301

Note-2: Avoid having @ in your password. Can use $ though.

Here's my understanding (non-authoritative):

ODBC is a technology-agnostic open standard supported by most software vendors. OLEDB is a technology-specific Microsoft's API from the COM-era (COM was a component and interoperability technology before .NET)

At some point various datasouce vendors (e.g. Oracle etc.), willing to be compatible with Microsoft data consumers, developed OLEDB providers for their products, but for the most part OLEDB remains a Microsoft-only standard. Now, most Microsoft data sources allow both ODBC and OLEDB access, mainly for compatibility with legacy ODBC data consumers. Also, there exists OLEDB provider (wrapper) for ODBC which allows one to use OLEDB to access ODBC data sources if one so wishes.

In terms of the features OLEDB is substantially richer than ODBC but suffers from one-ring-to-rule-them-all syndrome (overly generic, overcomplicated, non-opinionated).

In non-Microsoft world ODBC-based data providers and clients are widely used and not going anywhere.

Inside Microsoft bubble OLEDB is being phased out in favor of native .NET APIs build on top of whatever the native transport layer for that data source is (e.g. TDS for MS SQL Server).

In my case, I had started untar before the uploading of the tar file was complete.

In SQL Server 2016 you can use new DIE statements.

ALTER TABLE Table_name DROP COLUMN IF EXISTS Column_name

The above query is re-runnable it drops the column only if it exists in the table else it will not throw error.

Instead of using big IF wrappers to check the existence of column before dropping it you can just run the above DDL statement

Total cursors open, by session:

and b.name = 'opened cursors current';

Source: http://www.orafaq.com/node/758

As far as I know queries on v$ views are based on pseudo-tables ("x$" tables) that point directly to the relevant portions of the SGA, so you can't get more accurate than that; however this also means that it is point-in-time (i.e. dirty read).

You need to use the target selector.

If you're going to be adding the TimeOut directive, and your website uses multiple vhosts (eg. one for port 80, one for port 443), then don't forget to add the directive to all of them!

I know the question is aimed at the direct escaping of the apostrophe character but I assume that usually this is going to be triggered by some sort of program providing the input.

What I have done universally in the scripts and programs I have worked with is to substitute it with a ` character when processing the formatting of the text being input.

Now I know that in some cases, the backtick character may in fact be part of what you might be trying to save (such as on a forum like this) but if you're simply saving text input from users it's a possible solution.

Going into the SQL database

This example was when PERL/CGI is being used but it can apply to PHP and other bases as well. I have found it works well because I think it helps prevent possible injection attempts, because all ' are removed prior to attempting an insertion of a record.

When you return cell's contentView you will have a 2 problems:

1. crash related to gestures
2. you don't reusing contentView (every time on viewForHeaderInSection call, you creating new cell)

Solution:

Wrapper class for table header\footer. It is just container, inherited from UITableViewHeaderFooterView, which holds cell inside

https://github.com/Magnat12/MGTableViewHeaderWrapperView.git

Register class in your UITableView (for example, in viewDidLoad)

- (void)viewDidLoad {
    [super viewDidLoad];
    [self.tableView registerClass:[MGTableViewHeaderWrapperView class] forHeaderFooterViewReuseIdentifier:@"ProfileEditSectionHeader"];
}

In your UITableViewDelegate:

- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section {
    MGTableViewHeaderWrapperView *view = [tableView dequeueReusableHeaderFooterViewWithIdentifier:@"ProfileEditSectionHeader"];

    // init your custom cell
    ProfileEditSectionTitleTableCell *cell = (ProfileEditSectionTitleTableCell * ) view.cell;
    if (!cell) {
        cell = [tableView dequeueReusableCellWithIdentifier:@"ProfileEditSectionTitleTableCell"];
        view.cell = cell;
    }

    // Do something with your cell

    return view;
}

Write a simple class that subcalsses HttpServletRequestWrapper with a getParameter() method that returns the sanitized version of the input. Then pass an instance of your HttpServletRequestWrapper to Filter.doChain() instead of the request object directly.

I think you need to put it under src/main/resources and load it as follows:

props.load(new FileInputStream("src/main/resources/myconf.properties"));

The way you are trying to load it will first check in base folder of your project. If it is in target/classes and you want to load it from there do the following:

props.load(new FileInputStream("target/classes/myconf.properties"));

In this path find file cvtres.exe and rename it to cvtres1.exe then compile your project again.

Is a regular expression an easier/better way to enforce a simple constraint than the more obvious way?

static bool ValidatePassword( string password )
{
  const int MIN_LENGTH =  8 ;
  const int MAX_LENGTH = 15 ;

  if ( password == null ) throw new ArgumentNullException() ;

  bool meetsLengthRequirements = password.Length >= MIN_LENGTH && password.Length <= MAX_LENGTH ;
  bool hasUpperCaseLetter      = false ;
  bool hasLowerCaseLetter      = false ;
  bool hasDecimalDigit         = false ;

  if ( meetsLengthRequirements )
  {
    foreach (char c in password )
    {
      if      ( char.IsUpper(c) ) hasUpperCaseLetter = true ;
      else if ( char.IsLower(c) ) hasLowerCaseLetter = true ;
      else if ( char.IsDigit(c) ) hasDecimalDigit    = true ;
    }
  }

  bool isValid = meetsLengthRequirements
              && hasUpperCaseLetter
              && hasLowerCaseLetter
              && hasDecimalDigit
              ;
  return isValid ;

}

Which do you think that maintenance programmer 3 years from now who needs to modify the constraint will have an easier time understanding?

Wow, everyone's answer is so long. I simply used a pandas dataframe, masking, and the duplicated function (keep=False markes all duplicates as True, not just first or last):

int_df = pd.DataFrame({'int_list': np.random.randint(1, 20, size=10)})
dupes = int_df['int_list'].duplicated(keep=False)
print(int_df['int_list'][dupes].index)

This should return Int64Index([0, 2, 3, 4, 6, 7, 9], dtype='int64').

Well, it's not a direct answer to your question, but there's a tool in GNU/Linux whose job is to rotate log files on regular basis, keeping old ones zipped up to a certain limit. It's logrotate

Just my 2 cents as stated in the answer above : The copy() method shouldn't be used as-is for copying files without a slight adjustment:

function copy(callback) {
    var readStream = fs.createReadStream(oldPath);
    var writeStream = fs.createWriteStream(newPath);

    readStream.on('error', callback);
    writeStream.on('error', callback);

    // Do not callback() upon "close" event on the readStream
    // readStream.on('close', function () {
    // Do instead upon "close" on the writeStream
    writeStream.on('close', function () {
        callback();
    });

    readStream.pipe(writeStream);
}

The copy function wrapped in a Promise:

function copy(oldPath, newPath) {
  return new Promise((resolve, reject) => {
    const readStream = fs.createReadStream(oldPath);
    const writeStream = fs.createWriteStream(newPath);

    readStream.on('error', err => reject(err));
    writeStream.on('error', err => reject(err));

    writeStream.on('close', function() {
      resolve();
    });

    readStream.pipe(writeStream);
  })

However, keep in mind that the filesystem might crash if the target folder doesn't exist.

Always good idea is to make parent class, with functions ... i.e. add this all functionality to parent.

And "move" all classes that use this hierarchically down. I need - rewrite functions, which are specific.

Sure you could write that:

public static class Utils {
    public static bool IsAny<T>(this IEnumerable<T> data) {
        return data != null && data.Any();
    }
}

however, be cautious that not all sequences are repeatable; generally I prefer to only walk them once, just in case.

With Python 3.8 you can use the walrus operator and itertools.islice.

from itertools import islice

list_ = [i for i in range(10, 100)]

def chunker(it, size):
    iterator = iter(it)
    while chunk := list(islice(iterator, size)):
        print(chunk)

In [2]: chunker(list_, 10)                                                         
[10, 11, 12, 13, 14, 15, 16, 17, 18, 19]
[20, 21, 22, 23, 24, 25, 26, 27, 28, 29]
[30, 31, 32, 33, 34, 35, 36, 37, 38, 39]
[40, 41, 42, 43, 44, 45, 46, 47, 48, 49]
[50, 51, 52, 53, 54, 55, 56, 57, 58, 59]
[60, 61, 62, 63, 64, 65, 66, 67, 68, 69]
[70, 71, 72, 73, 74, 75, 76, 77, 78, 79]
[80, 81, 82, 83, 84, 85, 86, 87, 88, 89]
[90, 91, 92, 93, 94, 95, 96, 97, 98, 99]

In case you're using ASP.NET 5 with ASP.NET MVC 6, most of these answers simply won't work because you'll normally let MVC create the appropriate route collection for you (using the default RESTful conventions), meaning that you won't find any Routes.MapRoute() call to edit at will.

The ConfigureServices() method invoked by the Startup.cs file will register MVC with the Dependency Injection framework built into ASP.NET 5: that way, when you call ApplicationBuilder.UseMvc() later in that class, the MVC framework will automatically add these default routes to your app. We can take a look of what happens behind the hood by looking at the UseMvc() method implementation within the framework source code:

public static IApplicationBuilder UseMvc(
    [NotNull] this IApplicationBuilder app,
    [NotNull] Action<IRouteBuilder> configureRoutes)
{
    // Verify if AddMvc was done before calling UseMvc
    // We use the MvcMarkerService to make sure if all the services were added.
    MvcServicesHelper.ThrowIfMvcNotRegistered(app.ApplicationServices);

    var routes = new RouteBuilder
    {
        DefaultHandler = new MvcRouteHandler(),
        ServiceProvider = app.ApplicationServices
    };

    configureRoutes(routes);

    // Adding the attribute route comes after running the user-code because
    // we want to respect any changes to the DefaultHandler.
    routes.Routes.Insert(0, AttributeRouting.CreateAttributeMegaRoute(
        routes.DefaultHandler,
        app.ApplicationServices));

    return app.UseRouter(routes.Build());
}

The good thing about this is that the framework now handles all the hard work, iterating through all the Controller's Actions and setting up their default routes, thus saving you some redundant work.

The bad thing is, there's little or no documentation about how you could add your own routes. Luckily enough, you can easily do that by using either a Convention-Based and/or an Attribute-Based approach (aka Attribute Routing).

Convention-Based

In your Startup.cs class, replace this:

app.UseMvc();

with this:

app.UseMvc(routes =>
            {
                // Route Sample A
                routes.MapRoute(
                    name: "RouteSampleA",
                    template: "MyOwnGet",
                    defaults: new { controller = "Items", action = "Get" }
                );
                // Route Sample B
                routes.MapRoute(
                    name: "RouteSampleB",
                    template: "MyOwnPost",
                    defaults: new { controller = "Items", action = "Post" }
                );
            });

Attribute-Based

A great thing about MVC6 is that you can also define routes on a per-controller basis by decorating either the Controller class and/or the Action methods with the appropriate RouteAttribute and/or HttpGet / HttpPost template parameters, such as the following:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.AspNet.Mvc;

namespace MyNamespace.Controllers
{
    [Route("api/[controller]")]
    public class ItemsController : Controller
    {
        // GET: api/items
        [HttpGet()]
        public IEnumerable<string> Get()
        {
            return GetLatestItems();
        }

        // GET: api/items/5
        [HttpGet("{num}")]
        public IEnumerable<string> Get(int num)
        {
            return GetLatestItems(5);
        }       

        // GET: api/items/GetLatestItems
        [HttpGet("GetLatestItems")]
        public IEnumerable<string> GetLatestItems()
        {
            return GetLatestItems(5);
        }

        // GET api/items/GetLatestItems/5
        [HttpGet("GetLatestItems/{num}")]
        public IEnumerable<string> GetLatestItems(int num)
        {
            return new string[] { "test", "test2" };
        }

        // POST: /api/items/PostSomething
        [HttpPost("PostSomething")]
        public IActionResult Post([FromBody]string someData)
        {
            return Content("OK, got it!");
        }
    }
}

This controller will handle the following requests:

 [GET] api/items
 [GET] api/items/5
 [GET] api/items/GetLatestItems
 [GET] api/items/GetLatestItems/5
 [POST] api/items/PostSomething

Also notice that if you use the two approaches togheter, Attribute-based routes (when defined) would override Convention-based ones, and both of them would override the default routes defined by UseMvc().

For more info, you can also read the following post on my blog.

If you put an inverted comma at the start of the field, it will be interpreted as text.

Example: 25/12/2008 becomes '25/12/2008

You are also able to select the field type when importing.

You could use the timeout setting in the ajax options like this:

$.ajax({
    url: "test.html",
    timeout: 3000,
    error: function(){
        //do something
    },
    success: function(){
        //do something
    }
});

Read all about the ajax options here: http://api.jquery.com/jQuery.ajax/

Remember that when a timeout occurs, the error handler is triggered and not the success handler :)

Here are the high-level differences:

Forking

Pros

• Keeps branches separated by user
• Reduces clutter in the primary repository
• Your team process reflects the external contributor process

Cons

• Makes it more difficult to see all of the branches that are active (or inactive, for that matter)
• Collaborating on a branch is trickier (the fork owner needs to add the person as a collaborator)
• You need to understand the concept of multiple remotes in Git
  • Requires additional mental bookkeeping
  • This will make the workflow more difficult for people who aren't super comfortable with Git

Branching

Pros

• Keeps all of the work being done around a project in one place
• All collaborators can push to the same branch to collaborate on it
• There's only one Git remote to deal with

Cons

• Branches that get abandoned can pile up more easily
• Your team contribution process doesn't match the external contributor process
• You need to add team members as contributors before they can branch

If you are using tcsh, then edit your ~/.cshrc file to include the lines:

setenv CLICOLOR 1
setenv LSCOLORS dxfxcxdxbxegedabagacad

Where, like Martin says, LSCOLORS specifies the color scheme you want to use.

To generate the LSCOLORS you want to use, checkout this site

$("#button").click(function () { 
    $("#frame").attr("src", "http://www.example.com/");
});

HTML:

 <div id="mydiv">
     <iframe id="frame" src="" width="100%" height="300">
     </iframe>
 </div>
 <button id="button">Load</button>

You can also use setShowSoftInputOnFocus(boolean) directly on API 21+ or through reflection on API 14+:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
    editText.setShowSoftInputOnFocus(false);
} else {
    try {
        final Method method = EditText.class.getMethod(
                "setShowSoftInputOnFocus"
                , new Class[]{boolean.class});
        method.setAccessible(true);
        method.invoke(editText, false);
    } catch (Exception e) {
        // ignore
    }
}

FileUtils from apache commons is a pretty good way to achieve this in a single line.

FileOutputStream s = FileUtils.openOutputStream(new File("/home/nikhil/somedir/file.txt"))

This will create parent folders if do not exist and create a file if not exists and throw a exception if file object is a directory or cannot be written to. This is equivalent to:

File file = new File("/home/nikhil/somedir/file.txt");
file.getParentFile().mkdirs(); // Will create parent directories if not exists
file.createNewFile();
FileOutputStream s = new FileOutputStream(file,false);

All the above operations will throw an exception if the current user is not permitted to do the operation.

Use mongoexport/mongoimport to dump/restore a collection:

Export JSON File:

mongoexport --db <database-name> --collection <collection-name> --out output.json

Import JSON File:

mongoimport --db <database-name> --collection <collection-name> --file input.json

WARNING mongoimport and mongoexport do not reliably preserve all rich BSON data types because JSON can only represent a subset of the types supported by BSON. As a result, data exported or imported with these tools may lose some measure of fidelity.

Also, http://bsonspec.org/

BSON is designed to be fast to encode and decode. For example, integers are stored as 32 (or 64) bit integers, so they don't need to be parsed to and from text. This uses more space than JSON for small integers, but is much faster to parse.

In addition to compactness, BSON adds additional data types unavailable in JSON, notably the BinData and Date data types.

Try this code,

public void ConnectToAccess()
{
    System.Data.OleDb.OleDbConnection conn = new 
        System.Data.OleDb.OleDbConnection();
    // TODO: Modify the connection string and include any
    // additional required properties for your database.
    conn.ConnectionString = @"Provider=Microsoft.Jet.OLEDB.4.0;" +
        @"Data source= C:\Documents and Settings\username\" +
        @"My Documents\AccessFile.mdb";
    try
    {
        conn.Open();
        // Insert code to process data.
    }
        catch (Exception ex)
    {
        MessageBox.Show("Failed to connect to data source");
    }
    finally
    {
        conn.Close();
    }
}

You may want to use statement_timestamp(). This give the timestamp when the statement was executed. Whereas NOW() and CURRENT_TIMESTAMP give the timestamp when the transaction started.

The recent versions of XAMPP for Windows runs PHP 7.x which are NOT compatible with mbcrypt. If you have a package like Laravel that requires mbcrypt, you will need to install an older version of XAMPP. OR, you can run XAMPP with multiple versions of PHP by downloading a PHP package from Windows.PHP.net, installing it in your XAMPP folder, and configuring php.ini and httpd.conf to use the correct version of PHP for your site.

1. Go to Workspace location
2. select your project folder
3. .setting folder
4. edit "org.eclipse.wst.common.project.facet.core"
5. change installed facet="jst.web" version="3.0"

The question does not make clear what exactly you want to achieve.

List has the append method, which appends its argument to the list:

>>> list_one = [1,2,3]
>>> list_two = [4,5,6]
>>> list_one.append(list_two)
>>> list_one
[1, 2, 3, [4, 5, 6]]

There's also the extend method, which appends items from the list you pass as an argument:

>>> list_one = [1,2,3]
>>> list_two = [4,5,6]
>>> list_one.extend(list_two)
>>> list_one
[1, 2, 3, 4, 5, 6]

And of course, there's the insert method which acts similarly to append but allows you to specify the insertion point:

>>> list_one.insert(2, list_two)
>>> list_one
[1, 2, [4, 5, 6], 3, 4, 5, 6]

To extend a list at a specific insertion point you can use list slicing (thanks, @florisla):

>>> l = [1, 2, 3, 4, 5]
>>> l[2:2] = ['a', 'b', 'c']
>>> l
[1, 2, 'a', 'b', 'c', 3, 4, 5]

List slicing is quite flexible as it allows to replace a range of entries in a list with a range of entries from another list:

>>> l = [1, 2, 3, 4, 5]
>>> l[2:4] = ['a', 'b', 'c'][1:3]
>>> l
[1, 2, 'b', 'c', 5]

Set width

HeaderStyle-width

for Example HeaderStyle-width="10%"

This is an improvement on @thisisboris answer. It adds a current value to data, so the code can control when a variable set to the current value is changed.

(function()
{
    // Initialize the previous-attribute
    var selects = $( 'select' );
    $.each( selects, function( index, myValue ) {
        $( myValue ).data( 'mgc-previous', myValue.value );
        $( myValue ).data( 'mgc-current', myValue.value );  
    });

    // Listen on the body for changes to selects
    $('body').on('change', 'select',
        function()
        {
            alert('I am a body alert');
            $(this).data('mgc-previous', $(this).data( 'mgc-current' ) );
            $(this).data('mgc-current', $(this).val() );
        }
    );
})();

I normally configure the applicationContext using Annotation based configuration rather than XML based configuration. Anyway, I believe both of them have the same priority.

*Answering your question, system variable has higher priority *

Getting profile based beans from applicationContext

• Use @Profile on a Bean

@Component
@Profile("dev")
public class DatasourceConfigForDev

Now, the profile is dev

Note : if the Profile is given as @Profile("!dev") then the profile will exclude dev and be for all others.

• Use profiles attribute in XML

<beans profile="dev">
    <bean id="DatasourceConfigForDev" class="org.skoolguy.profiles.DatasourceConfigForDev"/>
</beans>

Set the value for profile:

• Programmatically via WebApplicationInitializer interface

  In web applications, WebApplicationInitializer can be used to configure the ServletContext programmatically

@Configuration
public class MyWebApplicationInitializer implements WebApplicationInitializer {

    @Override
    public void onStartup(ServletContext servletContext) throws ServletException {
            servletContext.setInitParameter("spring.profiles.active", "dev");
    }
}

• Programmatically via ConfigurableEnvironment

  You can also set profiles directly on the environment:

    @Autowired
    private ConfigurableEnvironment env;

    // ...

    env.setActiveProfiles("dev");

• Context Parameter in web.xml

  profiles can be activated in the web.xml of the web application as well, using a context parameter:

    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/app-config.xml</param-value>
    </context-param>
    <context-param>
        <param-name>spring.profiles.active</param-name>
        <param-value>dev</param-value>
    </context-param>

• JVM System Parameter

  The profile names passed as the parameter will be activated during application start-up:

  -Dspring.profiles.active=dev
  

  In IDEs, you can set the environment variables and values to use when an application runs. The following is the Run Configuration in Eclipse:

• Environment Variable

  to set via command line : export spring_profiles_active=dev

Any bean that does not specify a profile belongs to “default” profile.

The priority order is :

1. Context parameter in web.xml
2. WebApplicationInitializer
3. JVM System parameter
4. Environment variable

Ascii string to integer conversion is done by the atoi() function.

I will answer your question using a math analogy:

In this instance, the number 0 will represent no value. If you pick a random number, say 15, how many times can 0 be subtracted from 15? Infinite times because 0 has no value, thus you are taking nothing out of 15. Do you have difficulty accepting that 15 - 0 = 15 instead of ERROR? So if we switch this analogy back to Java coding, the String "" represents no value. Pick a random string, say "hello world", how many times can "" be subtracted from "hello world"?

System.out.format("|---------Test Cases with Steps Summary -------------|%n");

System.out.print("\033[0m"); // Close print red
System.out.format("+----------------------+---------+---------+---------+%n");
}

With reference This is an output-only I/O manipulator.

std::endl Inserts a newline character into the output sequence os and flushes it as if by calling os.put(os.widen('\n')) followed by os.flush().

When to use:

This manipulator may be used to produce a line of output immediately,

e.g.

when displaying output from a long-running process, logging activity of multiple threads or logging activity of a program that may crash unexpectedly.

Also

An explicit flush of std::cout is also necessary before a call to std::system, if the spawned process performs any screen I/O. In most other usual interactive I/O scenarios, std::endl is redundant when used with std::cout because any input from std::cin, output to std::cerr, or program termination forces a call to std::cout.flush(). Use of std::endl in place of '\n', encouraged by some sources, may significantly degrade output performance.

If you’re concerned about the file size of a PNG, you can use an SVG mask to create a transparent JPEG. Here is an example I put together.

From version 1.9 Easier and official way of getting json

from django.http import JsonResponse

return JsonResponse(  model_to_dict(modelinstance) )

There is no conversion between InputStream/OutputStream and the bytes they are working with. They are made for binary data, and just read (or write) the bytes one by one as is.

A conversion needs to happen when you want to go from byte to char. Then you need to convert using a character set. This happens when you make String or Reader from bytes, which are made for character data.

Turn the C Macro into a C# static method in a class.

Yet another solution:

string s = "??"; // or whatever

if (chldNode.Attributes.Cast<XmlAttribute>()
                       .Select(x => x.Value)
                       .Contains(attributeName))   
   s =  xe.Attributes[attributeName].Value;

It also avoids the exception when the expected attribute attributeName actually doesn't exist.

You can make Inheritance Inversion (look it up here: https://medium.com/@franleplant/react-higher-order-components-in-depth-cf9032ee6c3e). That way you have access to instance of the component that you would be wrapping (thus you'll be able to access it's functions)

Read about request objects that your views receive: https://docs.djangoproject.com/en/dev/ref/request-response/#httprequest-objects

Also your hidden field needs a reliable name and then a value:

<input type="hidden" name="title" value="{{ source.title }}">

Then in a view:

request.POST.get("title", "")

Use:

SELECT *
  FROM YOUR_TABLE
 WHERE creation_date <= TRUNC(SYSDATE) - 30

SYSDATE returns the date & time; TRUNC resets the date to being as of midnight so you can omit it if you want the creation_date that is 30 days previous including the current time.

Depending on your needs, you could also look at using ADD_MONTHS:

SELECT *
  FROM YOUR_TABLE
 WHERE creation_date <= ADD_MONTHS(TRUNC(SYSDATE), -1)

You cannot use Comparators for sorting primitive arrays.

Your best bet is to implement (or borrow an implementation) of a sorting algorithm that is appropriate for your use case to sort the array (in reverse order in your case).

I prefer TIMESTAMPDIFF because you can easily change the unit if need be.

Try this

  List<Address> list = geoCoder.getFromLocation(location
            .getLatitude(), location.getLongitude(), 1);
    if (list != null & list.size() > 0) {
        Address address = list.get(0);
        result = address.getLocality();
        return result;

You didn't give us much to go on here, but I think you're just asking how to add content to the beginning or end of an element? If so here's how you can do it pretty easily:

//get the target div you want to append/prepend to
var someDiv = document.getElementById("targetDiv");

//append text
someDiv.innerHTML += "Add this text to the end";

//prepend text
someDiv.innerHTML = "Add this text to the beginning" + someDiv.innerHTML;

Pretty easy.

You can do it more simply, guaranteeing that your .gitconfig is left in a meaningful state:

Using Git version v1.8.0 and above

git push -u hub master when pushing, or:
git branch -u hub/master

OR

(This will set the remote for the currently checked-out branch to hub/master)
git branch --set-upstream-to hub/master

OR

(This will set the remote for the branch named branch_name to hub/master)
git branch branch_name --set-upstream-to hub/master

If you're using v1.7.x or earlier

you must use --set-upstream:
git branch --set-upstream master hub/master

    Drawable d = Drawable.createFromStream(stream, null);

This is basically the same solution as @andy-wilkinson provided, but as of Spring Boot 1.0 the customize(...) method has a ConfigurableEmbeddedServletContainer parameter.

Another thing that is worth mentioning is that Tomcat only compresses content types of text/html, text/xml and text/plain by default. Below is an example that supports compression of application/json as well:

@Bean
public EmbeddedServletContainerCustomizer servletContainerCustomizer() {
    return new EmbeddedServletContainerCustomizer() {
        @Override
        public void customize(ConfigurableEmbeddedServletContainer servletContainer) {
            ((TomcatEmbeddedServletContainerFactory) servletContainer).addConnectorCustomizers(
                    new TomcatConnectorCustomizer() {
                        @Override
                        public void customize(Connector connector) {
                            AbstractHttp11Protocol httpProtocol = (AbstractHttp11Protocol) connector.getProtocolHandler();
                            httpProtocol.setCompression("on");
                            httpProtocol.setCompressionMinSize(256);
                            String mimeTypes = httpProtocol.getCompressableMimeTypes();
                            String mimeTypesWithJson = mimeTypes + "," + MediaType.APPLICATION_JSON_VALUE;
                            httpProtocol.setCompressableMimeTypes(mimeTypesWithJson);
                        }
                    }
            );
        }
    };
}

This bug still exists in 0.8+/1.10

With Jackson

compile 'com.fasterxml.jackson.dataformat:jackson-dataformat-csv:2.2.2'

I had to include as well as the above suggestion before it would compile

exclude 'META-INF/services/com.fasterxml.jackson.core.JsonFactory'

For Kotlin developers, remember the Java transient keyword becomes the built-in Kotlin @Transient annotation. Therefore, make sure you have the JPA import if you're using JPA @Transient in your entity:

import javax.persistence.Transient

Execute

set -o allexport

Any variables you source from a file after this will be exported in your shell.

source conf-file

When you're done execute. This will disable allexport mode.

set +o allexport

Modern browsers today seem to block (by default) these autoplay features. They are somewhat treated as pop-ops. Very intrusive. So yeah, users now have the complete control on when the sounds are played. ^[1,2,3]

HTML5 era

I restarted eclipse and did the Project -> Clean -> select your project One of them fixed my problem with adb

[2011-12-31 10:50:45 - HelloAndroid] Android Launch!                      good

[2011-12-31 10:50:45 - HelloAndroid] adb is running normally.             good

[2011-12-31 10:50:45 - HelloAndroid] Could not find HelloAndroid.apk!     bad

Thanks for the help. On to the next problem (sigh)

That's done for header files so that the contents only appear once in each preprocessed source file, even if it's included more than once (usually because it's included from other header files). The first time it's included, the symbol CLASS_H (known as an include guard) hasn't been defined yet, so all the contents of the file are included. Doing this defines the symbol, so if it's included again, the contents of the file (inside the #ifndef/#endif block) are skipped.

There's no need to do this for the source file itself since (normally) that's not included by any other files.

For your last question, class.h should contain the definition of the class, and declarations of all its members, associated functions, and whatever else, so that any file that includes it has enough information to use the class. The implementations of the functions can go in a separate source file; you only need the declarations to call them.

The following should do the trick:

div[class^='myclass'], div[class*=' myclass']{
    color: #F00;
}

Edit: Added wildcard (*) as suggested by David

To address why CMD is designed to run only one service per container, let's just realize what would happen if the secondary servers run in the same container are not trivial / auxiliary but "major" (e.g. storage bundled with the frontend app). For starters, it would break down several important containerization features such as horizontal (auto-)scaling and rescheduling between nodes, both of which assume there is only one application (source of CPU load) per container. Then there is the issue of vulnerabilities - more servers exposed in a container means more frequent patching of CVEs...

So let's admit that it is a 'nudge' from Docker (and Kubernetes/Openshift) designers towards good practices and we should not reinvent workarounds (SSH is not necessary - we have docker exec / kubectl exec / oc rsh designed to replace it).

The right answer for this question is "css reset".

* {
    margin: 0;
    padding: 0;
}

It removes all default margin and padding for every object on the page, no holds barred, regardless of browser.

This question is pretty old, but I just ran into a similar problem and my particular solution wasn't listed here:

Make sure you don't have a folder in your PATH that doesn't exist.

In my case, I had a bunch of default folders (Windows, Powershell, Sql Server, etc) and then a custom C:\bin that I typically use, and then various other tweaks like c:\python17, etc. It turns out that the cmd processor was finding that c:\bin didn't exist and then stopped processing the rest of the variable.

Also, I don't know that I ever would have noticed this without PATH manager. It nicely highlighted the fact that that item was invalid.

H.264 is a new standard for video compression which has more advanced compression methods than the basic MPEG-4 compression. One of the advantages of H.264 is the high compression rate. It is about 1.5 to 2 times more efficient than MPEG-4 encoding. This high compression rate makes it possible to record more information on the same hard disk.
The image quality is also better and playback is more fluent than with basic MPEG-4 compression. The most interesting feature however is the lower bit-rate required for network transmission.
So the 3 main advantages of H.264 over MPEG-4 compression are:
- Small file size for longer recording time and better network transmission.
- Fluent and better video quality for real time playback
- More efficient mobile surveillance application

H264 is now enshrined in MPEG4 as part 10 also known as AVC

Hope this helps.

This post itself is not a direct answer to the question. What it is instead is a data-driven extensible benchmark that can be used to compare many of the answers (and variations of utilizing new features added in later, more modern, versions of Python) that have been posted to this question — and should therefore be helpful in determining which has the best performance.

In a few cases I've modified the code in the referenced answer to make it compatible with the benchmark framework.

First, here are the results for what currently are the latest versions of Python 2 & 3:

Correct me if I'm wrong (I'm not), but the offset from UTC changes with daylight saving time. So you should use

tz = str.format('{0:+06.2f}', float(time.altzone) / 3600)

I also believe that the sign should be different:

tz = str.format('{0:+06.2f}', -float(time.altzone) / 3600)

I could be wrong, but I don't think so.

First, as for your Athlete class, you can remove your Getter and Setter methods since you have declared your instance variables with an access modifier of public. You can access the variables via <ClassName>.<variableName>.

However, if you really want to use that Getter and Setter, change the public modifier to private instead.

Second, for the constructor, you're trying to do a simple technique called shadowing. Shadowing is when you have a method having a parameter with the same name as the declared variable. This is an example of shadowing:
----------Shadowing sample----------
You have the following class:

public String name;

public Person(String name){
    this.name = name; // This is Shadowing
}

In your main method for example, you instantiate the Person class as follow:
Person person = new Person("theolc");

Variable name will be equal to "theolc".
----------End of shadowing----------

Let's go back to your question, if you just want to print the first element with your current code, you may remove the Getter and Setter. Remove your parameters on your constructor.

public class Athlete {

public String[] name = {"Art", "Dan", "Jen"};
public String[] country = {"Canada", "Germany", "USA"};

public Athlete() {

}

In your main method, you could do this.

public static void main(String[] args) {
       Athlete art = new Athlete();   

       System.out.println(art.name[0]);
       System.out.println(art.country[0]);
    }
}

None of the other solutions worked for me.

However, adding this to my package.json fixed the issue for me:

"resolutions": {
  "react-dev-utils": "10.0.0"
},

It can be determined by using following MySQL command

SELECT table_schema AS "Database", SUM(data_length + index_length) / 1024 / 1024 AS "Size (MB)" FROM information_schema.TABLES GROUP BY table_schema

Result

Database    Size (MB)
db1         11.75678253
db2         9.53125000
test        50.78547382

Get result in GB

SELECT table_schema AS "Database", SUM(data_length + index_length) / 1024 / 1024 / 1024 AS "Size (GB)" FROM information_schema.TABLES GROUP BY table_schema

Use of pointer before character array

Normally, Character array is used to store single elements in it i.e 1 byte each

eg:

char a[]={'a','b','c'};

we can't store multiple value in it.

by using pointer before the character array we can store the multi dimensional array elements in the array

i.e.

char *a[]={"one","two","three"};
printf("%s\n%s\n%s",a[0],a[1],a[2]);

This might be overkill - but be careful doing anything which relies on the extension of PHP files being .php - what if someone comes along later and adds handlers for .php4 or even .html so they're handled by PHP. You might be better off serving files out of those directories from a different instance of Apache or something, which only serves static content.

To get rid of the default dropdown arrow use:

-moz-appearance: window; 

while True:
    ...

means infinite loop.

The while statement is often used of a finite loop. But using the constant 'True' guarantees the repetition of the while statement without the need to control the loop (setting a boolean value inside the iteration for example), unless you want to break it.

In fact

True == (1 == 1)

Use print_r($votes); to inspect the array $votes, you will see that key 0 does not exist there. It will return NULL and throw that error.

The easiest thing to do is to run your program directly instead of through the IDE. Open a command prompt (Start->Run->Cmd.exe->Enter), cd to the folder where your project is, and run the program from there. That way, when the program exits, the prompt window sticks around and you can read all of the output.

Alternatively, you can also re-direct standard output to a file, but that's probably not what you are going for here.

Ternary way

my_string.include?('ahr') ? (puts 'String includes ahr') : (puts 'String does not include ahr')

OR

puts (my_string.include?('ahr') ? 'String includes ahr' : 'String not includes ahr')

I know this is an old post, but I wanted to add something I learned for the next folks who land here while googling.

In Powershell 5.1, you want to use continue to move onto the next item in your loop. I tested with 6 items in an array, had a foreach loop through, but put an if statement with:

foreach($i in $array){    
    write-host -fore green "hello $i"
    if($i -like "something"){
        write-host -fore red "$i is bad"
        continue
        write-host -fore red "should not see this"
    }
}

Of the 6 items, the 3rd one was something. As expected, it looped through the first 2, then the matching something gave me the red line where $i matched, I saw something is bad and then it went on to the next item in the array without saying should not see this. I tested with return and it exited the loop altogether.

Here's a solution which will work even when JavaScript is disabled:

<form action="login.html">
    <button type="submit">Login</button>
</form>

The trick is to surround the button with its own <form> tag.

I personally prefer the <button> tag, but you can do it with <input> as well:

<form action="login.html">
    <input type="submit" value="Login"/>
</form>

As noted by others, $('ul').empty() works fine, as does:

$('ul li').remove();

JS Fiddle demo.

In Excel 2007, goto Insert/Shape and pick a shape. Colour it and enter whatever text you want. Then right click on the shape and insert a hyperlink

A few tips with shapes..

If you want to easily position the shape with cells, hold down Alt when you move the shape and it will lock to the cell. If you don't want the shape to move or resize with rows/columns, right click the shape, select size and properties and choose the setting which works best.

Most pretty but basic:

data = {};
$.each(
    location.search.substr(1).split('&').filter(Boolean).map(function(kvpairs){
        return kvpairs.split('=')
    }),
    function(i,values) {
        data[values.shift()] = values.join('=')
    }
);

It doesn't handle values lists such as ?a[]=1&a[]2

You can define like this

define('GENERIC_DOMAIN',json_encode(array(
    'gmail.com','gmail.co.in','yahoo.com'
)));

$domains = json_decode(GENERIC_DOMAIN);
var_dump($domains);

The problem with most of these is that the user can still scroll up and see the addressbar. To make a permanent solution, you need to add this as well.

//WHENEVER the user scrolls
$(window).scroll(function(){
    //if you reach the top
    if ($(window).scrollTop() == 0)   
    //scroll back down  
    {window.scrollTo(1,1)}
})

When I used above code.It show me translated text as question mark like (???????).Then I convert from WebClient to HttpClient then I got a accurate result.So you can used code like this.

public static string TranslateText( string input, string languagePair)       
{
    string url = String.Format("http://www.google.com/translate_t?hl=en&ie=UTF8&text={0}&langpair={1}", input, languagePair);
    HttpClient httpClient = new HttpClient();
    string result = httpClient.GetStringAsync(url).Result;
    result = result.Substring(result.IndexOf("<span title=\"") + "<span title=\"".Length);
    result = result.Substring(result.IndexOf(">") + 1);
    result = result.Substring(0, result.IndexOf("</span>"));
    return result.Trim();
}

Then you Call a function like.You put first two letter of any language pair.

From English(en) To Urdu(ur).

TranslateText(line, "en|ur")

If you have a C++11 compiler you can prepare yourself for the future by using c++'s pseudo random number faculties:

//make sure to include the random number generators and such
#include <random>
//the random device that will seed the generator
std::random_device seeder;
//then make a mersenne twister engine
std::mt19937 engine(seeder());
//then the easy part... the distribution
std::uniform_int_distribution<int> dist(min, max);
//then just generate the integer like this:
int compGuess = dist(engine);

That might be slightly easier to grasp, being you don't have to do anything involving modulos and crap... although it requires more code, it's always nice to know some new C++ stuff...

Hope this helps - Luke
