To bind a UDP socket when receiving multicast means to specify an address and port from which to receive data (NOT a local interface, as is the case for TCP acceptor bind). The address specified in this case has a filtering role, i.e. the socket will only receive datagrams sent to that multicast address & port, no matter what groups are subsequently joined by the socket. This explains why when binding to INADDR_ANY (0.0.0.0) I received datagrams sent to my multicast group, whereas when binding to any of the local interfaces I did not receive anything, even though the datagrams were being sent on the network to which that interface corresponded.

Quoting from UNIX® Network Programming Volume 1, Third Edition: The Sockets Networking API by W.R Stevens. 21.10. Sending and Receiving

[...] We want the receiving socket to bind the multicast group and port, say 239.255.1.2 port 8888. (Recall that we could just bind the wildcard IP address and port 8888, but binding the multicast address prevents the socket from receiving any other datagrams that might arrive destined for port 8888.) We then want the receiving socket to join the multicast group. The sending socket will send datagrams to this same multicast address and port, say 239.255.1.2 port 8888.

This example doesn't work for me, for an obscure reason.

Not obscure, it's simple routing.

On OpenBSD

route add -inet 224.0.0.0/4 224.0.0.1

You can set the route to a dev on Linux

route add -net 224.0.0.0 netmask 240.0.0.0 dev wlp2s0

force all multicast traffic to one interface on Linux

   ifconfig wlp2s0 allmulti

tcpdump is super simple

tcpdump -n multicast

In your code you have:

while True:
  # For Python 3, change next line to "print(sock.recv(10240))"

Why 10240?

multicast packet size should be 1316 bytes

Here is a good example -

ul li{
    list-style-type: disc;
    list-style-position: inside;
    padding: 10px 0 10px 20px;
    text-indent: -1em;
}

Working Demo: http://jsfiddle.net/d9VNk/

I wasn't able to ever accomplish this but rather used view html source apps available on the Play Store to simply look for the element.

function

getValue(input){
        var value = input.value ? parseInt(input.value) : 0;
        let min = input.min;
        let max = input.max;
        if(value < min) 
            return parseInt(min); 
        else if(value > max) 
            return parseInt(max);
        else return value;
    }

Usages

changeDotColor = (event) => {
        let value = this.getValue(event.target) //value will be always number
        console.log(value)
        console.log(typeof value)
}

If you run it, it will work, but in order for SQL Developer to recognize and not warn about a possible error you can change it as:

ALTER TABLE TEST_PROJECT2 MODIFY (proj_name VARCHAR2(300));

Implicit and Explicit Waits

Implicit Wait

An implicit wait is to tell WebDriver to poll the DOM for a certain amount of time when trying to find an element or elements if they are not immediately available. The default setting is 0. Once set, the implicit wait is set for the life of the WebDriver object instance.

driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);

Explicit Wait + Expected Conditions

An explicit waits is code you define to wait for a certain condition to occur before proceeding further in the code. The worst case of this is Thread.sleep(), which sets the condition to an exact time period to wait. There are some convenience methods provided that help you write code that will wait only as long as required. WebDriverWait in combination with ExpectedCondition is one way this can be accomplished.

WebDriverWait wait = new WebDriverWait(driver, 10);
WebElement element = wait.until(
        ExpectedConditions.visibilityOfElementLocated(By.id("someid")));

The mysql.h file from the libmysqlclient-dev Ubuntu package is located at /usr/include/mysql/mysql.h.

This is not a standard search path for compilers, however /usr/include is.

You'd typically use the mysql.h header in your code like this:

#include <mysql/mysql.h>

If you don't want to specify the directory offset in your source, you can pass the -I flag to gcc (If that's what you are using) to specify an additional include search directory, and then you wouldn't need to change your existing code.

eg.

gcc -I/usr/include/mysql ...

This is useful when you have more than one class to append. You can join all classes in array with a space.

const visibility = this.props.showBulkActions ? "show" : ""
<div className={["btn-group pull-right", visibility].join(' ')}>

If the extension is not known, use this solution

 pathinfo('D:/dir1/dir2/fname', PATHINFO_FILENAME); // return "fname"
 pathinfo('D:/dir1/dir2/fname.php', PATHINFO_FILENAME); // return "fname"
 pathinfo('D:/dir1/dir2/fname.jpg', PATHINFO_FILENAME); // return "fname"

 pathinfo('D:/dir1/dir2/fname.jpg', PATHINFO_DIRNAME) . '/' . pathinfo('D:/dir1/dir2/fname.jpg', PATHINFO_FILENAME); // return "D:/dir1/dir2/fname"

PHP MAN function pathinfo

.schema TableName

Where TableName is the name of the Table

I have seen that the new versions when you define the resulting entities better define them in the following way if you handle a different scheme, I had a similar problem

You must add System.ComponentModel.DataAnnotations.Schema

using System.ComponentModel.DataAnnotations.Schema;


 [Table("InstitucionesMilitares", Schema = "configuracion")]

Wow, what a variety of causes of these error messages! I'll throw one more out:

In my case, Eclipse 4.17 on Ubuntu 16.04LTS was showing these messages for multiple operations. It turns out that 16.04LTS has GTK 3.18, but Eclipse 4.17 requires GTK 3.20. Updating GTK (https://askubuntu.com/questions/933010/how-to-upgrade-gtk-3-18-to-3-20-on-ubuntu-16-04) made the error messages go away.

Use this:

SELECT 
    Pieces, Price, 
    Pieces * Price as 'Total' 
FROM myTable

I think that it's absolutely absurd to put ALL of your function definitions into the header file. Why? Because the header file is used as the PUBLIC interface to your class. It's the outside of the "black box".

When you need to look at a class to reference how to use it, you should look at the header file. The header file should give a list of what it can do (commented to describe the details of how to use each function), and it should include a list of the member variables. It SHOULD NOT include HOW each individual function is implemented, because that's a boat load of unnecessary information and only clutters the header file.

You are going wrong here:

int retval = chooser.showOpenDialog(null); 
public boolean accept(File directory, String fileName) {`
return fileName.endsWith(".txt");`
}

You first show the file chooser dialog and then apply the filter! This wont work. First apply the filter and then show the dialog:

public boolean accept(File directory, String fileName) {
        return fileName.endsWith(".txt");
}
int retval = chooser.showOpenDialog(null);

For me the problem was copying .resx files and associated .cs files from one project to another. Both projects had the same namespace so that wasn't the problem.

Finally solved it when I noticed in Solution Explorer that in the original project the .resx files were dependent on the .cs files:

MyResource.cs
|_ MyResource.resx

While in the copied project the .cs files was dependent on the .resx files:

MyResource.resx
|_ MyResource.cs

It turned out that in the second project somehow the .resx files had been set to auto-generate the .cs files. The auto-generated .cs files were overwriting the .cs files copied from the original project.

To fix the problem edit the properties of each .resx file in the copied project. The Custom Tool property will be set to something like ResXFileCodeGenerator. Clear the Custom Tool property of the .resx file. You will need to re-copy the .cs file from the original project as it will have been overwritten by the auto-generated file.

I don't think this is the BEST solution, but it does appear to work. Instead of using the background color, I'm going to just embed an image of the background, position it relatively and then wrap the text in a child element and position it absolute - in the centre.

Initially, the result set object (rs) points to the BFR (before first record). Once we use rs.next(), the cursor points to the first record and the rs holds "true". Using the while loop you can print all the records of the table. After all the records are retrieved, the cursor moves to ALR (After last record) and it will be set to null. Let us consider that there are 2 records in the table.

if(rs.next()==false){
    // there are no records found
    }    

while (rs.next()==true){
    // print all the records of the table
    }

In short hand, we can also write the condition as while (rs.next()).

Click the items in the list view. Add a button that will edit the selected items. Add the code

try
{              
    LSTDEDUCTION.SelectedItems[0].SubItems[1].Text = txtcarName.Text;
    LSTDEDUCTION.SelectedItems[0].SubItems[0].Text = txtcarBrand.Text;
    LSTDEDUCTION.SelectedItems[0].SubItems[2].Text = txtCarName.Text;
}
catch{}

Python

element.get_attribute("attribute name")

Java

element.getAttribute("attribute name")

Ruby

element.attribute("attribute name")

C#

element.GetAttribute("attribute name");

List<SubProduct> subProducts= (List<SubProduct>)Model.subproduct;

The implicit conversion failes because List<> implements IList, not viceversa. So you can say IList<T> foo = new List<T>(), but not List<T> foo = (some IList-returning method or property).

If your function have two vector variables and must compute itself on each value of them (as mentioned by @Ari B. Friedman) you can use mapply as follows:

vars1<-c(1,2,3)
vars2<-c(10,20,30)
mult_one<-function(var1,var2)
{
   var1*var2
}
mapply(mult_one,vars1,vars2)

which gives you:

> mapply(mult_one,vars1,vars2)
[1] 10 40 90

This works for me on Xcode 6 & 5.

- (BOOL)shouldAutorotate {
    return YES;

}

You can copy-paste data from en excel-sheet to an SQL-table by doing so:

• Select the data in Excel and press Ctrl + C
• In SQL Server Management Studio right click the table and choose Edit Top 200 Rows
• Scroll to the bottom and select the entire empty row by clicking on the row header
• Paste the data by pressing Ctrl + V

Note: Often tables have a first column which is an ID-column with an auto generated/incremented ID. When you paste your data it will start inserting the leftmost selected column in Excel into the leftmost column in SSMS thus inserting data into the ID-column. To avoid that keep an empty column at the leftmost part of your selection in order to skip that column in SSMS. That will result in SSMS inserting the default data which is the auto generated ID.

Furthermore you can skip other columns by having empty columns at the same ordinal positions in the Excel sheet selection as those columns to be skipped. That will make SSMS insert the default value (or NULL where no default value is specified).

try install php5-curl by using below snippet.

sudo apt-get install php5-curl

if it won't work try below code i m sure it will work fine.

sudo apt-get install php-curl

for me it worked... all the best :)

The point about generics is to give compile-time type safety - which means that types need to be known at compile-time.

You can call generic methods with types only known at execution time, but you have to use reflection:

// For non-public methods, you'll need to specify binding flags too
MethodInfo method = GetType().GetMethod("DoesEntityExist")
                             .MakeGenericMethod(new Type[] { t });
method.Invoke(this, new object[] { entityGuid, transaction });

Ick.

Can you make your calling method generic instead, and pass in your type parameter as the type argument, pushing the decision one level higher up the stack?

If you could give us more information about what you're doing, that would help. Sometimes you may need to use reflection as above, but if you pick the right point to do it, you can make sure you only need to do it once, and let everything below that point use the type parameter in a normal way.

using LINQ and Lamba, i wanted to return two field values and assign it to single entity object field;

as Name = Fname + " " + LName;

See my below code which is working as expected; hope this is useful;

Myentity objMyEntity = new Myentity
{
id = obj.Id,
Name = contxt.Vendors.Where(v => v.PQS_ID == obj.Id).Select(v=> new { contact = v.Fname + " " + v.LName}).Single().contact
}

no need to declare the 'contact'

This method is easy to understand and works fine. The argument to the script ($1) is a reference (tag, hash, ...) to the commit starting from which you want to keep your history.

#!/bin/bash
git checkout --orphan temp $1 # create a new branch without parent history
git commit -m "Truncated history" # create a first commit on this branch
git rebase --onto temp $1 master # now rebase the part of master branch that we want to keep onto this branch
git branch -D temp # delete the temp branch

# The following 2 commands are optional - they keep your git repo in good shape.
git prune --progress # delete all the objects w/o references
git gc --aggressive # aggressively collect garbage; may take a lot of time on large repos

NOTE that old tags will still remain present; so you might need to remove them manually

remark: I know this is almost the same aswer as @yoyodin, but there are some important extra commands and informations here. I tried to edit the answer, but since it is a substantial change to @yoyodin's answer, my edit was rejected, so here's the information!

In regards to @RitchieD response, here is a jQuery plugin version to make things easier if you are using jQuery.

(function ($) {

    $.fn.initValidation = function () {

        $(this).removeData("validator");
        $(this).removeData("unobtrusiveValidation");
        $.validator.unobtrusive.parse(this);

        return this;
    };

}(jQuery));

This can be used like this:

$("#SomeForm").initValidation();

I often ended up doing things like this. Therefore I tried to write a simple function that 'snips' out the unwanted elements in an easy way. This turns matlab logic a bit upside down, but looks good:

b = snip(a,'0')

you can find the function file at: http://www.mathworks.co.uk/matlabcentral/fileexchange/41941-snip-m-snip-elements-out-of-vectorsmatrices

It also works with all other 'x', nan or whatever elements.

var guid = new Guid();

Hey, its a 'valid', although not very useful, Guid.

(the guid is all zeros, if you don't know. Sometimes this is needed to indicate no guid, in cases where you don't want to use a nullable Guid)

In C# and VB the SqlCommand object implements the Parameter.AddWithValue method which handles this situation

Here's what I did:

• Extracted the files using WinRAR
• Made my changes to the extracted files
• Opened the original JAR file with WinRAR
• Used the ADD button to replace the files that I modified

That's it. I have tested it with my Nokia and it's working for me.

You could iterate backwards and remove as you go through the ArrayList. This has the advantage of subsequent elements not needing to shift and is easier to program than moving forwards.

As per the question, i have listed the answers in javascript

By Selecting TagName

document.getElementsByTagName('textarea')[0].style.resize = "none";

By Selecting Id

document.getElementById('textArea').style.resize = "none";

Put a backslash (\) before the double quotes. That should work.

As you run the container, a directory on your host is created and mounted into the container. You can find out what directory this is with

$ docker inspect --format "{{ .Volumes }}" <ID>
map[/export:/var/lib/docker/vfs/dir/<VOLUME ID...>]

If you want to mount a directory from your host inside your container, you have to use the -v parameter and specify the directory. In your case this would be:

docker run -v /export:/export data

SO you would use the hosts folder inside your container.

What about making a simple function?

function isEmptyObject(obj) {
  for(var prop in obj) {
    if (Object.prototype.hasOwnProperty.call(obj, prop)) {
      return false;
    }
  }
  return true;
}

isEmptyObject({}); // true
isEmptyObject({foo:'bar'});  // false

The hasOwnProperty method call directly on the Object.prototype is only to add little more safety, imagine the following using a normal obj.hasOwnProperty(...) call:

isEmptyObject({hasOwnProperty:'boom'});  // false

Note: _{(for the future)} The above method relies on the for...in statement, and this statement iterates only over enumerable properties, in the currently most widely implemented ECMAScript Standard (3rd edition) the programmer doesn't have any way to create non-enumerable properties.

However this has changed now with ECMAScript 5th Edition, and we are able to create non-enumerable, non-writable or non-deletable properties, so the above method can fail, e.g.:

var obj = {};
Object.defineProperty(obj, 'test', { value: 'testVal', 
  enumerable: false,
  writable: true,
  configurable: true
});
isEmptyObject(obj); // true, wrong!!
obj.hasOwnProperty('test'); // true, the property exist!!

An ECMAScript 5 solution to this problem would be:

function isEmptyObject(obj) {
  return Object.getOwnPropertyNames(obj).length === 0;
}

The Object.getOwnPropertyNames method returns an Array containing the names of all the own properties of an object, enumerable or not, this method is being implemented now by browser vendors, it's already on the Chrome 5 Beta and the latest WebKit Nightly Builds.

Object.defineProperty is also available on those browsers and latest Firefox 3.7 Alpha releases.

If you're using Twitter Bootstrap Tooltip on non-link element, you can specify, that you want a multi-line tooltip directly in HTML code, without Javascript, using just the data parameter:

<span rel="tooltip" data-html="true" data-original-title="1<br />2<br />3">5</span>

This is just an alternative version of costales' answer. All the glory goes to him! :]

If you can safely make (firstName, lastName) the PRIMARY KEY or at least put a UNIQUE key on them, then you could do this:

INSERT INTO logins (firstName, lastName, logins) VALUES ('Steve', 'Smith', 1)
ON DUPLICATE KEY UPDATE logins = logins + 1;

If you can't do that, then you'd have to fetch whatever that primary key is first, so I don't think you could achieve what you want in one query.

result_array() returns Associative Array type data. Returning pure array is slightly faster than returning an array of objects. result() is recursive in that it returns an std class object where as result_array() just returns a pure array, so result_array() would be choice regarding performance.

You have invalid chars in your source. If you don't have any valid non ascii chars in your source, maybe in a double quoted string literal, you can simply convert your file back to ascii with:

tr -cd '\11\12\15\40-\176' < old.c > new.c

Edit: method with iconv will stop at wrong chars which makes no sense. The above command line is working with the example file. Good luck :-)

This code works for me to call the parent_fragment method from child_fragment.

ParentFragment parent = (ParentFragment) activity.getFragmentManager().findViewById(R.id.contaniner);

parent.callMethod();

Two options…

1. Set the format-detection meta tag.

To remove all auto-formatting for telephone numbers, add this to the head of your html document:

<meta name="format-detection" content="telephone=no">

View more Apple-Specific Meta Tag Keys.

Note: If you have phone numbers on the page with these numbers you should manually format them as links:

<a href="tel:+1-555-555-5555">1-555-555-5555</a>

2. Can’t set a meta tag? Want to use css?

Two css options:

Option 1 (better for web pages)

Target links with href values starting with tel by using this css attribute selector:

a[href^="tel"] {
  color: inherit; /* Inherit text color of parent element. */
  text-decoration: none; /* Remove underline. */
  /* Additional css `propery: value;` pairs here */
}

Option 2 (better for html email templates)

Alternatively, you can when you can’t set a meta tag—such as in html email—wrap phone numbers in link/anchor tags (<a href=""></a>) and then target their styles using css similar to the following and adjust the specific properties you need to reset:

a[x-apple-data-detectors] {
  color: inherit !important;
  text-decoration: none !important;
  font-size: inherit !important;
  font-family: inherit !important;
  font-weight: inherit !important;
  line-height: inherit !important;
}

If you want to target specific links, use classes on your links and then update the css selector above to a[x-apple-data-detectors].class-name.

Have you tried simply opening them in OpenOffice.org?

I had a similar problem some time ago and found that Excel and Calc didn't understand each other's encryption, and so allowed direct access to just about everything.

This was a while ago, so if that wasn't just a fluke on my part it also may have been patched.

If you only have one bean of type EmployeeService, and the interface EmployeeService does not have other implementations, you can simply put "@Service" before the EmployeeServiceImpl and "@Autowire" before the setter method. Otherwise, you should name the special bean like @Service("myspecial") and put "@autowire @Qualifier("myspecial") before the setter method.

As mentioned by Zeeshan, the logrotate options size, minsize, maxsize are triggers for rotation.

To better explain it. You can run logrotate as often as you like, but unless a threshold is reached such as the filesize being reached or the appropriate time passed, the logs will not be rotated.

The size options do not ensure that your rotated logs are also of the specified size. To get them to be close to the specified size you need to call the logrotate program sufficiently often. This is critical.

For log files that build up very quickly (e.g. in the hundreds of MB a day), unless you want them to be very large you will need to ensure logrotate is called often! this is critical.

Therefore to stop your disk filling up with multi-gigabyte log files you need to ensure logrotate is called often enough, otherwise the log rotation will not work as well as you want.

on Ubuntu, you can easily switch to hourly rotation by moving the script /etc/cron.daily/logrotate to /etc/cron.hourly/logrotate

Or add

*/5 * * * * /etc/cron.daily/logrotate 

To your /etc/crontab file. To run it every 5 minutes.

The size option ignores the daily, weekly, monthly time options. But minsize & maxsize take it into account.

The man page is a little confusing there. Here's my explanation.

minsize rotates only when the file has reached an appropriate size and the set time period has passed. e.g. minsize 50MB + daily If file reaches 50MB before daily time ticked over, it'll keep growing until the next day.

maxsize will rotate when the log reaches a set size or the appropriate time has passed. e.g. maxsize 50MB + daily. If file is 50MB and we're not at the next day yet, the log will be rotated. If the file is only 20MB and we roll over to the next day then the file will be rotated.

size will rotate when the log > size. Regardless of whether hourly/daily/weekly/monthly is specified. So if you have size 100M - it means when your log file is > 100M the log will be rotated if logrotate is run when this condition is true. Once it's rotated, the main log will be 0, and a subsequent run will do nothing.

So in the op's case. Specficially 50MB max I'd use something like the following:

/var/log/logpath/*.log {
    maxsize 50M
    hourly
    missingok
    rotate 8
    compress
    notifempty
    nocreate
}

Which means he'd create 8hrs of logs max. And there would be 8 of them at no more than 50MB each. Since he's saying that he's getting multi gigabytes each day and assuming they build up at a fairly constant rate, and maxsize is used he'll end up with around close to the max reached for each file. So they will be likely close to 50MB each. Given the volume they build, he would need to ensure that logrotate is run often enough to meet the target size.

Since I've put hourly there, we'd need logrotate to be run a minimum of every hour. But since they build up to say 2 gigabytes per day and we want 50MB... assuming a constant rate that's 83MB per hour. So you can imagine if we run logrotate every hour, despite setting maxsize to 50 we'll end up with 83MB log's in that case. So in this instance set the running to every 30 minutes or less should be sufficient.

Ensure logrotate is run every 30 mins.

*/30 * * * * /etc/cron.daily/logrotate 

check with either:

   ps -edaf | grep mongo | grep -v grep  # "ps" flags may differ on your OS

or

   /etc/init.d/mongodb status     # for MongoDB version < 2.6

   /etc/init.d/mongod status      # for MongoDB version >= 2.6

or

   service mongod status

to see if mongod is running (you need to be root to do this, or prefix everything with sudo). Please note that the 'grep' command will always also show up as a separate process.

check the log file /var/log/mongo/mongo.log to see if there are any problems reported

Perhaps not the most efficient solution, but certainly short & simple:

def repstr(string, length):
    return (string * length)[0:length]

repstr("foobar", 14)

Gives "foobarfoobarfo". One thing about this version is that if length < len(string) then the output string will be truncated. For example:

repstr("foobar", 3)

Gives "foo".

Edit: actually to my surprise, this is faster than the currently accepted solution (the 'repeat_to_length' function), at least on short strings:

from timeit import Timer
t1 = Timer("repstr('foofoo', 30)", 'from __main__ import repstr')
t2 = Timer("repeat_to_length('foofoo', 30)", 'from __main__ import repeat_to_length')
t1.timeit()  # gives ~0.35 secs
t2.timeit()  # gives ~0.43 secs

Presumably if the string was long, or length was very high (that is, if the wastefulness of the string * length part was high) then it would perform poorly. And in fact we can modify the above to verify this:

from timeit import Timer
t1 = Timer("repstr('foofoo' * 10, 3000)", 'from __main__ import repstr')
t2 = Timer("repeat_to_length('foofoo' * 10, 3000)", 'from __main__ import repeat_to_length')
t1.timeit()  # gives ~18.85 secs
t2.timeit()  # gives ~1.13 secs

You can store the array's elements in a row or column as follows:

>>> a = np.array([1, 2, 3])[:, None] # stores in rows
>>> a
array([[1],
       [2],
       [3]])

>>> b = np.array([1, 2, 3])[None, :] # stores in columns
>>> b
array([[1, 2, 3]])

If we need to list the installed packages in the Python shell, we can use the help command as follows

>>> help('modules package')

This works for me:

input.valid {_x000D_
   border-color: #28a745;_x000D_
   padding-right: 30px;_x000D_
   background-image: url('https://www.stephenwadechryslerdodgejeep.com/wp-content/plugins/pm-motors-plugin/modules/vehicle_save/images/check.png');_x000D_
   background-repeat: no-repeat;_x000D_
   background-size: 20px 20px;_x000D_
   background-position: right center;_x000D_
}

<form>_x000D_
<label for="name">Name</label>_x000D_
<input class="valid" type="text" name="name" />_x000D_
</form>

You may want to use something like this:

NSDateComponents *components;
NSInteger days;

components = [[NSCalendar currentCalendar] components: NSDayCalendarUnit 
        fromDate: startDate toDate: endDate options: 0];
days = [components day];

I believe this method accounts for situations such as dates that span a change in daylight savings.

Scenario: You did a big clean up of your code by using your IDE. Problem: The IDE cleaned up more than it should and now you code does not compile (missing resources, etc.)

Solution:

git grep --cached "text_to_find"

It will find the file where "text_to_find" was changed.

You can now undo this change and compile your code.

Here's mine - works for really big files too -_-

function formatFileSize(size)
{
    var sizes = [' Bytes', ' KB', ' MB', ' GB', ' TB', ' PB', ' EB', ' ZB', ' YB'];
    for (var i = 1; i < sizes.length; i++)
    {
        if (size < Math.pow(1024, i)) return (Math.round((size/Math.pow(1024, i-1))*100)/100) + sizes[i-1];
    }
    return size;
}

I was able to get Jenkins to build a tag by setting the Refspec and Branch Specifier as detailed in this blog post.

I also had to set the Repository Name (to "origin" in my case) so that I could reference it in the Refspec (otherwise it would apparently use a randomly generated name).

Try this: sudo systemctl start mongod and to check whether its running use sudo systemctl status mongod

After allocating DateFormatter you need to give the formatted string then you can convert as string like this way

var date = Date()
let formatter = DateFormatter()
formatter.dateFormat = "yyyy-MM-dd HH:mm:ss"
let myString = formatter.string(from: date)
let yourDate: Date? = formatter.date(from: myString)
formatter.dateFormat = "dd-MMM-yyyy"
let updatedString = formatter.string(from: yourDate!)
print(updatedString)

OutPut

01-Mar-2017

You can merge, or you can apply individual commits across branches by using git cherry-pick.

The return statement sets the exit code of the function, much the same as exit will do for the entire script.

The exit code for the last command is always available in the $? variable.

function fun1(){
  return 34
}

function fun2(){
  local res=$(fun1)
  echo $? # <-- Always echos 0 since the 'local' command passes.

  res=$(fun1)
  echo $?  #<-- Outputs 34
}

python -m pip install Pillow

Will use pip of current Python activated with

There's a difference between additive colors (http://en.wikipedia.org/wiki/Additive_color) and subtractive colors (http://en.wikipedia.org/wiki/Subtractive_color).

With additive colors, the more you add, the brighter the colors become. This is because they are emitting light. This is why the day light is (more or less) white, since the Sun is emitting in almost all the visible wavelength spectrum.

On the other hand, with subtractive colors the more colors you mix, the darker the resulting color. This is because they are reflecting light. This is also why the black colors get hotter quickly, because it absorbs (almost) all light energy and reflects (almost) none.

Specifically to your question, it depends what medium you are working on. Traditionally, additive colors (RGB) are used because the canon for computer graphics was the computer monitor, and since it's emitting light, it makes sense to use the same structure for the graphic card (the colors are shown without conversions). However, if you are used to graphic arts and press, subtractive color model is used (CMYK). In programs such as Photoshop, you can choose to work in CMYK space although it doesn't matter what color model you use: the primary colors of one group are the secondary colors of the second one and viceversa.

P.D.: my father worked at graphic arts, this is why i know this... :-P

As Grodriguez says, Integer objects are immutable. The problem here is that you're trying to increment the int value of the player ID rather than the ID itself. In Java 5+, you can just write playerID++.

As a side note, never ever call Integer's constructor. Take advantage of autoboxing by just assigning ints to Integers directly, like Integer foo = 5. This will use Integer.valueOf(int) transparently, which is superior to the constructor because it doesn't always have to create a new object.

Default JDK supports encryption only through 128 bit keys becuase of American restrictions. So to support encryption from 256 bit long key we have to replace local_policy.jar and US_export_policy.jars in $JAVA_HOME/java-8-oracle/jre/lib/security folder otherwise it will give:

java.security.InvalidKeyException: Illegal key size or default

Struggling with this myself. This is my take:

https://gist.github.com/2639448:

require 'csv'

class CSV
  def CSV.unparse array
    CSV.generate do |csv|
      array.each { |i| csv << i }
    end
  end
end

CSV.unparse [ %w(your array), %w(goes here) ]

git clone --depth 1 --branch <tag_name> <repo_url>

--depth 1 is optional but if you only need the state at that one revision, you probably want to skip downloading all the history up to that revision.

You could define a macro containing the following code:

Sub DeleteA5X50()   
    Range("A5:X50").Select
    Selection.ClearContents
end sub

Running the macro would select the range A5:x50 on the active worksheet and clear all the contents of the cells within that range.

To leave your formulas intact use the following instead:

Sub DeleteA5X50()   
    Range("A5:X50").Select
    Selection.SpecialCells(xlCellTypeConstants, 23).Select
    Selection.ClearContents
end sub

This will first select the overall range of cells you are interested in clearing the contents from and will then further limit the selection to only include cells which contain what excel considers to be 'Constants.'

You can do this manually in excel by selecting the range of cells, hitting 'f5' to bring up the 'Go To' dialog box and then clicking on the 'Special' button and choosing the 'Constants' option and clicking 'Ok'.

Your question title and your question body are different. Ruby does not have a starts_with? method. Rails, which is a Ruby framework, however, does, as sepp2k states. See his comment on his answer for the link to the documentation for it.

You could always use a regular expression though:

if SomeString.match(/^abc/) 
   # SomeString starts with abc

^ means "start of string" in regular expressions

For [1], you can't: these operators are made to return a value, not perform operations.

The expression

a ? b : c

evaluates to b if a is true and evaluates to c if a is false.

The expression

b ?? c

evaluates to b if b is not null and evaluates to c if b is null.

If you write

return a ? b : c;

or

return b ?? c;

they will always return something.

For [2], you can write a function that returns the right value that performs your "multiple operations", but that's probably worse than just using if/else.

You array is being allocated on the stack in this case attempt to allocate an array of the same size using alloc.

var string ='my string'
var new_string = string.replace('string','new string');
alert(string);
alert(new_string);

I'd like to present a compact solution using a call by reference (yes, "batch" has pointers too!) to a function, and a "subfunction":

  @ECHO OFF
  SETLOCAL ENABLEDELAYEDEXPANSION

  SET /p NAME=- NAME ? 
  ECHO "%NAME%"
  CALL :TRIM NAME
  ECHO "%NAME%"
  GOTO :EOF

  :TRIM
  SetLocal EnableDelayedExpansion
  Call :TRIMSUB %%%1%%
  EndLocal & set %1=%tempvar%
  GOTO :EOF

  :TRIMSUB
  set tempvar=%*
  GOTO :EOF

This is my implementation (based in: https://gist.github.com/3782074):

Usage: HTML:

<table class="download">...</table>
<a href="" download="name.csv">DOWNLOAD CSV</a>

JS:

$("a[download]").click(function(){
    $("table.download").toCSV(this);    
});

Code:

jQuery.fn.toCSV = function(link) {
  var $link = $(link);
  var data = $(this).first(); //Only one table
  var csvData = [];
  var tmpArr = [];
  var tmpStr = '';
  data.find("tr").each(function() {
      if($(this).find("th").length) {
          $(this).find("th").each(function() {
            tmpStr = $(this).text().replace(/"/g, '""');
            tmpArr.push('"' + tmpStr + '"');
          });
          csvData.push(tmpArr);
      } else {
          tmpArr = [];
             $(this).find("td").each(function() {
                  if($(this).text().match(/^-{0,1}\d*\.{0,1}\d+$/)) {
                      tmpArr.push(parseFloat($(this).text()));
                  } else {
                      tmpStr = $(this).text().replace(/"/g, '""');
                      tmpArr.push('"' + tmpStr + '"');
                  }
             });
          csvData.push(tmpArr.join(','));
      }
  });
  var output = csvData.join('\n');
  var uri = 'data:application/csv;charset=UTF-8,' + encodeURIComponent(output);
  $link.attr("href", uri);
}

Notes:

• It uses "th" tags for headings. If they are not present, they are not added.
• This code detects numbers in the format: -####.## (You will need modify the code in order to accept other formats, e.g. using commas).

UPDATE:

My previous implementation worked fine but it didn't set the csv filename. The code was modified to use a filename but it requires an < a > element. It seems that you can't dynamically generate the < a > element and fire the "click" event (perhaps security reasons?).

DEMO

http://jsfiddle.net/nLj74t0f/

(Unfortunately jsfiddle fails to generate the file and instead it throws an error: 'please use POST request', don't let that error stop you from testing this code in your application).

These two are quite different:

Default methods are to add external functionality to existing classes without changing their state.

And abstract classes are a normal type of inheritance, they are normal classes which are intended to be extended.

Depending on your definition of "special character", I think "[^a-zA-Z0-9]" would probably do the trick. That would find anything that is not a small letter, a capital letter, or a digit.

You are not creating a separate dictionary for each iframe, you just keep modifying the same dictionary over and over, and you keep adding additional references to that dictionary in your list.

Remember, when you do something like content.append(info), you aren't making a copy of the data, you are simply appending a reference to the data.

You need to create a new dictionary for each iframe.

for iframe in soup.find_all('iframe'):
   info = {}
    ...

Even better, you don't need to create an empty dictionary first. Just create it all at once:

for iframe in soup.find_all('iframe'):
    info = {
        "src":    iframe.get('src'),
        "height": iframe.get('height'),
        "width":  iframe.get('width'),
    }
    content.append(info)

There are other ways to accomplish this, such as iterating over a list of attributes, or using list or dictionary comprehensions, but it's hard to improve upon the clarity of the above code.

I had a similar problem on OSX 10.11 due to installing memcached which installed python 3.7 on top of 3.6.

WARNING: pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.

Spent hours on unlinking openssl, reinstalling, changing paths.. and nothing helped. Changing openssl version back from to older version did the trick:

brew switch openssl 1.0.2e

I did not see this suggestion anywhere in internet. Hope it serves someone.

drawable.equals(null)

The above line calls the "equals(...)" method on the drawable object.

So, when drawable is not null and it is a real object, then all goes well as calling the "equals(null)" method will return "false"

But when "drawable" is null, then it means calling the "equals(...)" method on null object, means calling a method on an object that doesn't exist so it throws "NullPointerException"

To check whether an object exists and it is not null, use the following

if(drawable == null) {
    ...
    ...
}

In above condition, we are checking that the reference variable "drawable" is null or contains some value (reference to its object) so it won't throw exception in case drawable is null as checking

null == null

is valid.

you can use Self-Executing Anonymous Functions. this code will work:

<a href="#" onClick="(function(){
    alert('Hey i am calling');
    return false;
})();return false;">click here</a>

see JSfiddle

This answer supposes support for look around! This allowed me to identify all the text between pairs of opening and closing tags. That is all the text between the '>' and the '<'. It works because look around doesn't consume the characters it matches.

(?<=>)([\w\s]+)(?=<\/)

I tested it in https://regex101.com/ using this HTML fragment.

<table>
<tr><td>Cell 1</td><td>Cell 2</td><td>Cell 3</td></tr>
<tr><td>Cell 4</td><td>Cell 5</td><td>Cell 6</td></tr>
</table>

It's a game of three parts: the look behind, the content, and the look ahead.

(?<=>)    # look behind (but don't consume/capture) for a '>'
([\w\s]+) # capture/consume any combination of alpha/numeric/whitespace
(?=<\/)   # look ahead  (but don't consume/capture) for a '</'

I hope that serves as a started for 10. Luck.

Update 2016:

Unfortunately most of the above solutions are out of date and no longer maintained.

There are 3 additional options I can suggest that are still actively developed:

1. BrowseEmAll.Cef

A .Net component that can be used to integrate the Chrome engine into your .Net Application. Based on CefGlue but a little faster on updates to the latest Chrome version. Also there is a commercial support option available which might come in handy for some. Of course the component itself is open source.

2. BrowseEmAll.Gecko

Another .Net component which can be used to integrate the Firefox engine into your .Net application. This is based on Geckofx but unlike the current version of Geckofx this will work with a normal release build of Firefox. To use Geckofx you will need to build Firefox yourself. Again commercial support is available but the component itself is fully open source.

3. BrowseEmAll Core API

Need all the different browsers in your .Net Application? Which the BrowseEmAll Core API you can integrate Chrome, Firefox, Webkit and Internet Explorer into your application. This is a commercial product though so be warned.

(Full disclosure: I work for this company so take everything I say with a grain of salt)

in my case, after encrypting password,I forgot to put settings-security.xml into ~/.m2?

Another way that doesn't use group by:

SELECT * FROM tblpm n 
  WHERE date_updated=(SELECT date_updated FROM tblpm n 
                        ORDER BY date_updated desc LIMIT 1)

well! you can actually create a bunch of custom HTML attributes by disguising the data attributes in what you actually want.

eg.

[attribute='value']{
color:red;
}

<span attribute="value" >hello world</span>

It apparently works but that would invalidate your document, there is no need of using JScript for you to have custom attributes or even elements unless you have to, you just need to treat your new formulated(custom) attributes just the same way you treat your "data" attribute

Remember "invalid" does not mean anything. The document will load fine at all the time. and some browsers would actually validate your document only by the presence of DOCTYPE....., you actually know what I mean.

Note: If your app targets API level 26 or higher, the system imposes restrictions on using or creating background services unless the app itself is in the foreground.

If an app needs to create a foreground service, the app should call startForegroundService(). That method creates a background service, but the method signals to the system that the service will promote itself to the foreground.

Once the service has been created, the service must call its startForeground() method within five seconds.

A module in Angular 2 is something which is made from components, directives, services etc. One or many modules combine to make an Application. Modules breakup application into logical pieces of code. Each module performs a single task.

Components in Angular 2 are classes where you write your logic for the page you want to display. Components control the view (html). Components communicate with other components and services.

You can do some Javascript in the form's submit event. That's all you can do though, there's no way to get browsers to do this by themselves. It also means your form will break for users without Javascript. Better is to know on the server which checkboxes there are, so you can deduce that those absent from the posted form values ($_POST in PHP) are unchecked.

OuterClass.this references the outer class.

It works for me:

Today is: 31/03/2012

echo date("Y-m-d", strtotime(date('m', mktime() - 31*3600*24).'/01/'.date('Y').' 00:00:00')); // 2012-02-01
echo  date("Y-m-d", mktime() - 31*3600*24); // 2012-02-29

Simply replace image/jpeg with application/octet-stream. The client would not recognise the URL as an inline-able resource, and prompt a download dialog.

A simple JavaScript solution would be:

//var img = reference to image
var url = img.src.replace(/^data:image\/[^;]+/, 'data:application/octet-stream');
window.open(url);
// Or perhaps: location.href = url;
// Or even setting the location of an <iframe> element, 

Another method is to use a blob: URI:

var img = document.images[0];
img.onclick = function() {
    // atob to base64_decode the data-URI
    var image_data = atob(img.src.split(',')[1]);
    // Use typed arrays to convert the binary data to a Blob
    var arraybuffer = new ArrayBuffer(image_data.length);
    var view = new Uint8Array(arraybuffer);
    for (var i=0; i<image_data.length; i++) {
        view[i] = image_data.charCodeAt(i) & 0xff;
    }
    try {
        // This is the recommended method:
        var blob = new Blob([arraybuffer], {type: 'application/octet-stream'});
    } catch (e) {
        // The BlobBuilder API has been deprecated in favour of Blob, but older
        // browsers don't know about the Blob constructor
        // IE10 also supports BlobBuilder, but since the `Blob` constructor
        //  also works, there's no need to add `MSBlobBuilder`.
        var bb = new (window.WebKitBlobBuilder || window.MozBlobBuilder);
        bb.append(arraybuffer);
        var blob = bb.getBlob('application/octet-stream'); // <-- Here's the Blob
    }

    // Use the URL object to create a temporary URL
    var url = (window.webkitURL || window.URL).createObjectURL(blob);
    location.href = url; // <-- Download!
};

Yes it is 100% possible

set classpath= %classpath%;d:\jansi-1.4.jar;

Try this below code:

import org.fusesource.jansi.AnsiConsole;
import static org.fusesource.jansi.Ansi.*;
import static org.fusesource.jansi.Ansi.Color.*;

public class Sample

{

  public static void main(String[] args)
  {
    AnsiConsole.systemInstall();

    System.out.println(ansi().fg(RED).a("Hello World").reset());
    System.out.println("My Name is Raman");

    AnsiConsole.systemUninstall();
  }
}

Compatibility Supports Says that Under compatibility level 110, the default style for CAST and CONVERT operations on time and datetime2 data types is always 121. If your query relies on the old behavior, use a compatibility level less than 110, or explicitly specify the 0 style in the affected query.

That means by default datetime2 is CAST as varchar to 121 format. For ex; col1 and col2 formats (below) are same (other than the 0s at the end)

SELECT CONVERT(varchar, GETDATE(), 121) col1,
       CAST(convert(datetime2,GETDATE()) as varchar) col2,
       CAST(GETDATE() as varchar) col3

FYI, if you use CONVERT instead of CAST you can use a third parameter to specify certain formats as listed here on MSDN

You could also get all relevant details from performance_schema:

GROUP BY
OBJECT_SCHEMA
,OBJECT_NAME

This works similar as

Firstly, you should read this page thoroughly http://codex.wordpress.org/AJAX_in_Plugins

Secondly, ajax_script is not defined so you should change to: url: ajaxurl. I don't see your function1() in the above code but you might already define it in other file.

And finally, learn how to debug ajax call using Firebug, network and console tab will be your friends. On the PHP side, print_r() or var_dump() will be your friends.

For ES6/ES2015 you can import directly like:

// example.json
{
    "name": "testing"
}


// ES6/ES2015
// app.js
import * as data from './example.json';
const word = data.name;
console.log(word); // output 'testing'

If you use typescript, you may declare json module like:

// tying.d.ts
declare module "*.json" {
    const value: any;
    export default value;
}

Or you can always map over an iterator, without the need to build an intermediate list:

>>> _ = map(sys.stdout.write, (x for x in string.letters if x in (y for y in "BigMan on campus")))

You need to call the AddAddress method once for every recipient. Like so:

$mail->AddAddress('[email protected]', 'Person One');
$mail->AddAddress('[email protected]', 'Person Two');
// ..

Better yet, add them as Carbon Copy recipients.

$mail->AddCC('[email protected]', 'Person One');
$mail->AddCC('[email protected]', 'Person Two');
// ..

To make things easy, you should loop through an array to do this.

$recipients = array(
   '[email protected]' => 'Person One',
   '[email protected]' => 'Person Two',
   // ..
);
foreach($recipients as $email => $name)
{
   $mail->AddCC($email, $name);
}

It is quite simple because you are using the FXMLBuilder.

Just follow these simple steps:

1. Open FXML file into FXMLBuilder.
2. Select the stack pane.
3. Open the Layout tab [left side tab of FXMLBuilder].
4. Set the sides value by which you want to compute the pane size during stage resize like TOP, LEFT, RIGHT, BOTTOM.

max-width is the width of the target display area, e.g. the browser

max-device-width is the width of the device's entire rendering area, i.e. the actual device screen

Same goes for max-height and max-device-height naturally.

I upgraded from 2010 to 2013 and after changing all the projects' Platform Toolset, I need to right-click on the Solution and choose Retarget... to make it work.

Before actually answering your question:

Parameters in a URL (e.g. key=listOfUsers/user1) are GET parameters and you shouldn't be using them for POST requests. A quick explanation of the difference between GET and POST can be found here.

In your case, to make use of REST principles, you should probably have:

http://ip:5000/users
http://ip:5000/users/<user_id>

Then, on each URL, you can define the behaviour of different HTTP methods (GET, POST, PUT, DELETE). For example, on /users/<user_id>, you want the following:

GET /users/<user_id> - return the information for <user_id>
POST /users/<user_id> - modify/update the information for <user_id> by providing the data
PUT - I will omit this for now as it is similar enough to `POST` at this level of depth
DELETE /users/<user_id> - delete user with ID <user_id> 

So, in your example, you want do a POST to /users/user_1 with the POST data being "John". Then the XPath expression or whatever other way you want to access your data should be hidden from the user and not tightly couple to the URL. This way, if you decide to change the way you store and access data, instead of all your URL's changing, you will simply have to change the code on the server-side.

Now, the answer to your question: Below is a basic semi-pseudocode of how you can achieve what I mentioned above:

from flask import Flask
from flask import request

app = Flask(__name__)

@app.route('/users/<user_id>', methods = ['GET', 'POST', 'DELETE'])
def user(user_id):
    if request.method == 'GET':
        """return the information for <user_id>"""
        .
        .
        .
    if request.method == 'POST':
        """modify/update the information for <user_id>"""
        # you can use <user_id>, which is a str but could
        # changed to be int or whatever you want, along
        # with your lxml knowledge to make the required
        # changes
        data = request.form # a multidict containing POST data
        .
        .
        .
    if request.method == 'DELETE':
        """delete user with ID <user_id>"""
        .
        .
        .
    else:
        # POST Error 405 Method Not Allowed
        .
        .
        .

There are a lot of other things to consider like the POST request content-type but I think what I've said so far should be a reasonable starting point. I know I haven't directly answered the exact question you were asking but I hope this helps you. I will make some edits/additions later as well.

Thanks and I hope this is helpful. Please do let me know if I have gotten something wrong.

$ rails server -b $IP -p $PORT - that solved the same problem for me

Floats and doubles are approximate. If you create a BigDecimal and pass a float into the constructor you see what the float actually equals:

groovy:000> new BigDecimal(1.0F)
===> 1
groovy:000> new BigDecimal(1.01F)
===> 1.0099999904632568359375

this probably isn't how you want to represent $1.01.

The problem is that the IEEE spec doesn't have a way to exactly represent all fractions, some of them end up as repeating fractions so you end up with approximation errors. Since accountants like things to come out exactly to the penny, and customers will be annoyed if they pay their bill and after the payment is processed they owe .01 and they get charged a fee or can't close their account, it's better to use exact types like decimal (in C#) or java.math.BigDecimal in Java.

It's not that the error isn't controllable if you round: see this article by Peter Lawrey. It's just easier not to have to round in the first place. Most applications that handle money don't call for a lot of math, the operations consist of adding things or allocating amounts to different buckets. Introducing floating point and rounding just complicates things.

The most straightforward solution is to make the rows a single item by making them strings. Each row then can be compared as a whole for its uniqueness using numpy. This solution is generalize-able you just need to reshape and transpose your array for other combinations. Here is the solution for the problem provided.

import numpy as np

original = np.array([[1, 1, 1, 0, 0, 0],
       [0, 1, 1, 1, 0, 0],
       [0, 1, 1, 1, 0, 0],
       [1, 1, 1, 0, 0, 0],
       [1, 1, 1, 1, 1, 0]])

uniques, index = np.unique([str(i) for i in original], return_index=True)
cleaned = original[index]
print(cleaned)    

Will Give:

 array([[0, 1, 1, 1, 0, 0],
        [1, 1, 1, 0, 0, 0],
        [1, 1, 1, 1, 1, 0]])

SQL Server 2012 and Later

Just use Try_Convert instead:

TRY_CONVERT takes the value passed to it and tries to convert it to the specified data_type. If the cast succeeds, TRY_CONVERT returns the value as the specified data_type; if an error occurs, null is returned. However if you request a conversion that is explicitly not permitted, then TRY_CONVERT fails with an error.

Read more about Try_Convert.

SQL Server 2008 and Earlier

The traditional way of handling this is by guarding every expression with a case statement so that no matter when it is evaluated, it will not create an error, even if it logically seems that the CASE statement should not be needed. Something like this:

SELECT
   Account_Code =
      Convert(
         bigint, -- only gives up to 18 digits, so use decimal(20, 0) if you must
         CASE
         WHEN X.Account_Code LIKE '%[^0-9]%' THEN NULL
         ELSE X.Account_Code
         END
      ),
   A.Descr
FROM dbo.Account A
WHERE
   Convert(
      bigint,
      CASE
      WHEN X.Account_Code LIKE '%[^0-9]%' THEN NULL
      ELSE X.Account_Code
      END
   ) BETWEEN 503100 AND 503205

However, I like using strategies such as this with SQL Server 2005 and up:

SELECT
   Account_Code = Convert(bigint, X.Account_Code),
   A.Descr
FROM
   dbo.Account A
   OUTER APPLY (
      SELECT A.Account_Code WHERE A.Account_Code NOT LIKE '%[^0-9]%'
   ) X
WHERE
   Convert(bigint, X.Account_Code) BETWEEN 503100 AND 503205

What this does is strategically switch the Account_Code values to NULL inside of the X table when they are not numeric. I initially used CROSS APPLY but as Mikael Eriksson so aptly pointed out, this resulted in the same error because the query parser ran into the exact same problem of optimizing away my attempt to force the expression order (predicate pushdown defeated it). By switching to OUTER APPLY it changed the actual meaning of the operation so that X.Account_Code could contain NULL values within the outer query, thus requiring proper evaluation order.

You may be interested to read Erland Sommarskog's Microsoft Connect request about this evaluation order issue. He in fact calls it a bug.

There are additional issues here but I can't address them now.

P.S. I had a brainstorm today. An alternate to the "traditional way" that I suggested is a SELECT expression with an outer reference, which also works in SQL Server 2000. (I've noticed that since learning CROSS/OUTER APPLY I've improved my query capability with older SQL Server versions, too--as I am getting more versatile with the "outer reference" capabilities of SELECT, ON, and WHERE clauses!)

SELECT
   Account_Code =
      Convert(
         bigint,
         (SELECT A.AccountCode WHERE A.Account_Code NOT LIKE '%[^0-9]%')
      ),
   A.Descr
FROM dbo.Account A
WHERE
   Convert(
      bigint,
      (SELECT A.AccountCode WHERE A.Account_Code NOT LIKE '%[^0-9]%')
   ) BETWEEN 503100 AND 503205

It's a lot shorter than the CASE statement.

In my case ,I created a project and made its minSdkVersion=9 and targetSdkVersion=17. I used automatically generated libs/android-support-v4.jar. I also had to make use of ActionBarActivity using android-support-v7-appcomapt.jar. So I just copied the android-support-v7-appcompat.jar file from android-sdk/extras/andrid/support/v7/appcompat/libs folder and pasted it to my project libs folder. And this caused the above error. So basically,I needed to put android-support-v4.jar file from android-sdk/extras/andrid/support/v7/appcompat/libs as well to my project libs folder. As per my knowledge the v7.jar file had dependencies on v4.jar file. So ,it needed it own v4.jarfile,instead of my project,automatically created v4.jar file.

I was installing appium by npm install -g appium and getting the same error on Windows 10.

Below command worked for me:

npm --add-python-to-path='true' --debug install --global windows-build-tools

Thread

Thread represents an actual OS-level thread, with its own stack and kernel resources. (technically, a CLR implementation could use fibers instead, but no existing CLR does this) Thread allows the highest degree of control; you can Abort() or Suspend() or Resume() a thread (though this is a very bad idea), you can observe its state, and you can set thread-level properties like the stack size, apartment state, or culture.

The problem with Thread is that OS threads are costly. Each thread you have consumes a non-trivial amount of memory for its stack, and adds additional CPU overhead as the processor context-switch between threads. Instead, it is better to have a small pool of threads execute your code as work becomes available.

There are times when there is no alternative Thread. If you need to specify the name (for debugging purposes) or the apartment state (to show a UI), you must create your own Thread (note that having multiple UI threads is generally a bad idea). Also, if you want to maintain an object that is owned by a single thread and can only be used by that thread, it is much easier to explicitly create a Thread instance for it so you can easily check whether code trying to use it is running on the correct thread.

ThreadPool

ThreadPool is a wrapper around a pool of threads maintained by the CLR. ThreadPool gives you no control at all; you can submit work to execute at some point, and you can control the size of the pool, but you can't set anything else. You can't even tell when the pool will start running the work you submit to it.

Using ThreadPool avoids the overhead of creating too many threads. However, if you submit too many long-running tasks to the threadpool, it can get full, and later work that you submit can end up waiting for the earlier long-running items to finish. In addition, the ThreadPool offers no way to find out when a work item has been completed (unlike Thread.Join()), nor a way to get the result. Therefore, ThreadPool is best used for short operations where the caller does not need the result.

Task

Finally, the Task class from the Task Parallel Library offers the best of both worlds. Like the ThreadPool, a task does not create its own OS thread. Instead, tasks are executed by a TaskScheduler; the default scheduler simply runs on the ThreadPool.

Unlike the ThreadPool, Task also allows you to find out when it finishes, and (via the generic Task) to return a result. You can call ContinueWith() on an existing Task to make it run more code once the task finishes (if it's already finished, it will run the callback immediately). If the task is generic, ContinueWith() will pass you the task's result, allowing you to run more code that uses it.

You can also synchronously wait for a task to finish by calling Wait() (or, for a generic task, by getting the Result property). Like Thread.Join(), this will block the calling thread until the task finishes. Synchronously waiting for a task is usually bad idea; it prevents the calling thread from doing any other work, and can also lead to deadlocks if the task ends up waiting (even asynchronously) for the current thread.

Since tasks still run on the ThreadPool, they should not be used for long-running operations, since they can still fill up the thread pool and block new work. Instead, Task provides a LongRunning option, which will tell the TaskScheduler to spin up a new thread rather than running on the ThreadPool.

All newer high-level concurrency APIs, including the Parallel.For*() methods, PLINQ, C# 5 await, and modern async methods in the BCL, are all built on Task.

Conclusion

The bottom line is that Task is almost always the best option; it provides a much more powerful API and avoids wasting OS threads.

The only reasons to explicitly create your own Threads in modern code are setting per-thread options, or maintaining a persistent thread that needs to maintain its own identity.

You could look into this: http://www.codeproject.com/KB/showcase/pdfrasterizer.aspx It's not completely free, but it looks very nice.

Alex

The following should work. The lambda function filter out the duplicated words.

inputs=[]
input = raw_input("Word: ").strip()
while input:
    inputs.append(input)
    input = raw_input("Word: ").strip()
uniques=reduce(lambda x,y: ((y in x) and x) or x+[y], inputs, [])
print 'There are', len(uniques), 'unique words'

Without explicitly defining the height I determined I need to apply the flex value to the parent and grandparent div elements...

<div style="display: flex;">
<div style="display: flex;">
 <img alt="No, he'll be an engineer." src="theknack.png" style="margin: auto;" />
</div>
</div>

If you're using a single element (e.g. dead-centered text in a single flex element) use the following:

align-items: center;
display: flex;
justify-content: center;

You can tag your DOM element using #someTag, then get it with @ViewChild('someTag').

See complete example:

import {AfterViewInit, Component, ElementRef, ViewChild} from '@angular/core';

@Component({
    selector: 'app',
    template: `
        <div #myDiv>Some text</div>
    `,
})
export class AppComponent implements AfterViewInit {
    @ViewChild('myDiv') myDiv: ElementRef;

    ngAfterViewInit() {
        console.log(this.myDiv.nativeElement.innerHTML);
    }
}

console.log will print Some text.

There are several long standing discussions about how to do this in a consistent, well understood and portable way. No complete resolution but I'll link you to the discussions below.

In any event you many want to try using the --add-host option to docker run to add the ip address of the host into the container's /etc/host file. From there it's trivial to connect to the host on any required port:

Adding entries to a container hosts file

You can add other hosts into a container's /etc/hosts file by using one or more --add-host flags. This example adds a static address for a host named docker:

 $ docker run --add-host=docker:10.180.0.1 --rm -it debian
    $$ ping docker
    PING docker (10.180.0.1): 48 data bytes
    56 bytes from 10.180.0.1: icmp_seq=0 ttl=254 time=7.600 ms
    56 bytes from 10.180.0.1: icmp_seq=1 ttl=254 time=30.705 ms
    ^C--- docker ping statistics ---
    2 packets transmitted, 2 packets received, 0% packet loss
    round-trip min/avg/max/stddev = 7.600/19.152/30.705/11.553 ms

Note: Sometimes you need to connect to the Docker host, which means getting the IP address of the host. You can use the following shell commands to simplify this process:

 $ alias hostip="ip route show 0.0.0.0/0 | grep -Eo 'via \S+' | awk '{ print $2 }'"
 $ docker run  --add-host=docker:$(hostip) --rm -it debian

If I may offer some suggestions (two years later but hopefully helpful to future readers):

• Factor out the common h2 element.
• Factor out the common ooooooooooooo text.
• Be aware of new XPath 2.0 if/then/else construct if using XSLT 2.0.

XSLT 1.0 Solution ^{_{(also works with XSLT 2.0)}}

<h2>
  <xsl:choose>
    <xsl:when test="$CreatedDate > $IDAppendedDate">m</xsl:when>
    <xsl:otherwise>d</xsl:otherwise>
  </xsl:choose>
  ooooooooooooo
</h2>

XSLT 2.0 Solution

<h2>
   <xsl:value-of select="if ($CreatedDate > $IDAppendedDate) then 'm' else 'd'"/>
   ooooooooooooo
</h2>

None of the above answers worked for me, but here's what did.

1) delete .git/ from your project
2) clone the remote repo to some new location like your desktop. git clone https://github.com/foo/bar.git
3) move .git/ from the new location into the old location
4) re-commit and push your changes

If you need a directive more advanced, I recomend the solution that I implemnted, correctly tested on Internet Explorer 11, Chrome and FireFox.

I hope it, will be helpfull.

Using the <source /> tags proved difficult for me in Chrome 14.0.835.202 specifically, although it worked fine for me in FireFox. (This could be my lack of knowledge, but I thought an alternate solution might be useful anyway.) So, I ended up just using a <video /> tag and setting the src attribute right on the video tag itself. The canPlayVideo('<mime type>') function was used to determine whether or not the specific browser could play the input video. The following works in FireFox and Chrome.

Incidently, both FireFox and Chrome are playing the "ogg" format, although Chrome recommends "webm". I put the check for browser support of "ogg" first only because other posts have mentioned that FireFox prefers the ogg source first (i.e. <source src="..." type="video/ogg"/> ). But, I haven't tested (and highly doubt) whether or not it the order in the code makes any difference at all when setting the "src" on the video tag.

HTML

<body onload="setupVideo();">
    <video id="media" controls="true" preload="auto" src="">
    </video>
</body>

JavaScript

function setupVideo() {
       // You will probably get your video name differently
       var videoName = "http://video-js.zencoder.com/oceans-clip.mp4";

       // Get all of the uri's we support
       var indexOfExtension = videoName.lastIndexOf(".");
       //window.alert("found index of extension " + indexOfExtension);
       var extension = videoName.substr(indexOfExtension, videoName.length - indexOfExtension);
       //window.alert("extension is " + extension);
       var ogguri = encodeURI(videoName.replace(extension, ".ogv"));
       var webmuri = encodeURI(videoName.replace(extension, ".webm"));
       var mp4uri = encodeURI(videoName.replace(extension, ".mp4"));
       //window.alert(" URI is " + webmuri);


       // Get the video element
       var v = document.getElementById("media");
       window.alert(" media is " + v);

       // Test for support
       if (v.canPlayType("video/ogg")) {
            v.setAttribute("src", ogguri);
           //window.alert("can play ogg");
       }
       else if (v.canPlayType("video/webm")) {
           v.setAttribute("src", webmuri);
           //window.alert("can play webm");
       }
       else if (v.canPlayType("video/mp4")) {
           v.setAttribute("src", mp4uri);
           //window.alert("can play mp4");
       }
       else {
           window.alert("Can't play anything");
       }

      v.load();
      v.play();
  }

To answer that question, I'd like to describe member's accessors first in my own words. If you already know this, skip to the heading "next:".

There are three accessors that I'm aware of: public, protected and private.

Let:

class Base {
    public:
        int publicMember;
    protected:
        int protectedMember;
    private:
        int privateMember;
};

• Everything that is aware of Base is also aware that Base contains publicMember.
• Only the children (and their children) are aware that Base contains protectedMember.
• No one but Base is aware of privateMember.

By "is aware of", I mean "acknowledge the existence of, and thus be able to access".

next:

The same happens with public, private and protected inheritance. Let's consider a class Base and a class Child that inherits from Base.

• If the inheritance is public, everything that is aware of Base and Child is also aware that Child inherits from Base.
• If the inheritance is protected, only Child, and its children, are aware that they inherit from Base.
• If the inheritance is private, no one other than Child is aware of the inheritance.

If your browser supports CSS3, try using the CSS element Calc()

height: calc(100% - 65px);

you might also want to adding browser compatibility options:

height: -o-calc(100% - 65px); /* opera */
height: -webkit-calc(100% - 65px); /* google, safari */
height: -moz-calc(100% - 65px); /* firefox */

also make sure you have spaces between values, see: https://stackoverflow.com/a/16291105/427622

Got it! I found an idea here

http://www.mail-archive.com/[email protected]/msg18410.html

In this example, they loaded a blank popup window into an object, cloned the contents of the element to be displayed, and appended it to the body of the object. Since I already knew what the contents of view-details (or any page I load in the lightbox), I just had to clone that content instead and load it into an object. Then, I just needed to print that object. The final outcome looks like this:

$('.printBtn').bind('click',function() {
    var thePopup = window.open( '', "Customer Listing", "menubar=0,location=0,height=700,width=700" );
    $('#popup-content').clone().appendTo( thePopup.document.body );
    thePopup.print();
});

I had one small drawback in that the style sheet I was using in view-details.php was using a relative link. I had to change it to an absolute link. The reason being that the window didn't have a URL associated with it, so it had no relative position to draw on.

Works in Firefox. I need to test it in some other major browsers too.

I don't know how well this solution works when you're dealing with images, videos, or other process intensive solutions. Although, it works pretty well in my case, since I'm just loading tables and text values.

Thanks for the input! You gave me some ideas of how to get around this.

If you have Python 2.6 or newer, use format:

'{0:.3g}'.format(num)

For Python 2.5 or older:

'%.3g'%(num)

Explanation:

{0}tells format to print the first argument -- in this case, num.

Everything after the colon (:) specifies the format_spec.

.3 sets the precision to 3.

g removes insignificant zeros. See http://en.wikipedia.org/wiki/Printf#fprintf

For example:

tests=[(1.00, '1'),
       (1.2, '1.2'),
       (1.23, '1.23'),
       (1.234, '1.23'),
       (1.2345, '1.23')]

for num, answer in tests:
    result = '{0:.3g}'.format(num)
    if result != answer:
        print('Error: {0} --> {1} != {2}'.format(num, result, answer))
        exit()
    else:
        print('{0} --> {1}'.format(num,result))

yields

1.0 --> 1
1.2 --> 1.2
1.23 --> 1.23
1.234 --> 1.23
1.2345 --> 1.23

Using Python 3.6 or newer, you could use f-strings:

In [40]: num = 1.234; f'{num:.3g}'
Out[40]: '1.23'

First off all I would like to thanks @MaximShoustin.

Thanks of you I have really nice table.

I provide some small modification in $scope.range and $scope.setPage.

In this way I have now possibility to go to the last page or come back to the first page. Also when I'm going to next or prev page the navigation is changing when $scope.gap is crossing. And the current page is not always on first position. For me it's looking more nicer.

Here is the new fiddle example: http://jsfiddle.net/qLBRZ/3/

You can do something like:

int countSetBits(int n)
{
    n=((n&0xAAAAAAAA)>>1) + (n&0x55555555);
    n=((n&0xCCCCCCCC)>>2) + (n&0x33333333);
    n=((n&0xF0F0F0F0)>>4) + (n&0x0F0F0F0F);
    n=((n&0xFF00FF00)>>8) + (n&0x00FF00FF);
    return n;
}

int main()
{
    int n=10;
    printf("Number of set bits: %d",countSetBits(n));
     return 0;
}

See heer: http://ideone.com/JhwcX

The working can be explained as follows:

First, all the even bits are shifted towards right & added with the odd bits to count the number of bits in group of two. Then we work in group of two, then four & so on..

I have faced the same issue with COMDLG32.OCX and MSFLXGRD.OCX in Windows 10 and Visual Studio 2010. It's an MFC application.

Then I downloaded its zip file from the google after extracting copy them at following paths:

C:\Windows\System32 (*For 32-bit machine*)
C:\Windows\SysWOW64 (*For 64-bit machine*)

Then run Command Prompt as an Administrator then run the following commands:

For Windows 64-bit systems c:\windows\SysWOW64\ regsvr32 comdlg32.ocx
c:\windows\SysWOW64\regsvr32 msflxgrd.ocx (My machine is 64-bit configuration)

For Windows 32-bit systems c:\windows\System32\ regsvr32 comdlg32.ocx

c:\windows\System32\regsvr32 msflxgrd.ocx

On successfully updation of the above cmds it shows succeed message.

The best thing is to actually use the kernel makefile to install the module:

Here is are snippets to add to your Makefile

around the top add:

PWD=$(shell pwd)
VER=$(shell uname -r)
KERNEL_BUILD=/lib/modules/$(VER)/build
# Later if you want to package the module binary you can provide an INSTALL_ROOT
# INSTALL_ROOT=/tmp/install-root

around the end add:

install:
        $(MAKE) -C $(KERNEL_BUILD) M=$(PWD) \
           INSTALL_MOD_PATH=$(INSTALL_ROOT) modules_install

and then you can issue

    sudo make install

this will put it either in /lib/modules/$(uname -r)/extra/

or /lib/modules/$(uname -r)/misc/

and run depmod appropriately

I don't know how exactly the bottom sheet of the new Maps app, responds to user interactions. But you can create a custom view that looks like the one in the screenshots and add it to the main view.

I assume you know how to:

1- create view controllers either by storyboards or using xib files.

2- use googleMaps or Apple's MapKit.

Example

1- Create 2 view controllers e.g, MapViewController and BottomSheetViewController. The first controller will host the map and the second is the bottom sheet itself.

Configure MapViewController

Create a method to add the bottom sheet view.

func addBottomSheetView() {
    // 1- Init bottomSheetVC
    let bottomSheetVC = BottomSheetViewController()

    // 2- Add bottomSheetVC as a child view 
    self.addChildViewController(bottomSheetVC)
    self.view.addSubview(bottomSheetVC.view)
    bottomSheetVC.didMoveToParentViewController(self)

    // 3- Adjust bottomSheet frame and initial position.
    let height = view.frame.height
    let width  = view.frame.width
    bottomSheetVC.view.frame = CGRectMake(0, self.view.frame.maxY, width, height)
}

And call it in viewDidAppear method:

override func viewDidAppear(animated: Bool) {
    super.viewDidAppear(animated)
    addBottomSheetView()
}

Configure BottomSheetViewController

1) Prepare background

Create a method to add blur and vibrancy effects

func prepareBackgroundView(){
    let blurEffect = UIBlurEffect.init(style: .Dark)
    let visualEffect = UIVisualEffectView.init(effect: blurEffect)
    let bluredView = UIVisualEffectView.init(effect: blurEffect)
    bluredView.contentView.addSubview(visualEffect)

    visualEffect.frame = UIScreen.mainScreen().bounds
    bluredView.frame = UIScreen.mainScreen().bounds

    view.insertSubview(bluredView, atIndex: 0)
}

call this method in your viewWillAppear

override func viewWillAppear(animated: Bool) {
   super.viewWillAppear(animated)
   prepareBackgroundView()
}

Make sure that your controller's view background color is clearColor.

2) Animate bottomSheet appearance

override func viewDidAppear(animated: Bool) {
    super.viewDidAppear(animated)

    UIView.animateWithDuration(0.3) { [weak self] in
        let frame = self?.view.frame
        let yComponent = UIScreen.mainScreen().bounds.height - 200
        self?.view.frame = CGRectMake(0, yComponent, frame!.width, frame!.height)
    }
}

3) Modify your xib as you want.

4) Add Pan Gesture Recognizer to your view.

In your viewDidLoad method add UIPanGestureRecognizer.

override func viewDidLoad() {
    super.viewDidLoad()

    let gesture = UIPanGestureRecognizer.init(target: self, action: #selector(BottomSheetViewController.panGesture))
    view.addGestureRecognizer(gesture)

}

And implement your gesture behaviour:

func panGesture(recognizer: UIPanGestureRecognizer) {
    let translation = recognizer.translationInView(self.view)
    let y = self.view.frame.minY
    self.view.frame = CGRectMake(0, y + translation.y, view.frame.width, view.frame.height)
     recognizer.setTranslation(CGPointZero, inView: self.view)
}

Scrollable Bottom Sheet:

If your custom view is a scroll view or any other view that inherits from, so you have two options:

First:

Design the view with a header view and add the panGesture to the header. (bad user experience).

Second:

1 - Add the panGesture to the bottom sheet view.

2 - Implement the UIGestureRecognizerDelegate and set the panGesture delegate to the controller.

3- Implement shouldRecognizeSimultaneouslyWith delegate function and disable the scrollView isScrollEnabled property in two case:

• The view is partially visible.
• The view is totally visible, the scrollView contentOffset property is 0 and the user is dragging the view downwards.

Otherwise enable scrolling.

  func gestureRecognizer(_ gestureRecognizer: UIGestureRecognizer, shouldRecognizeSimultaneouslyWith otherGestureRecognizer: UIGestureRecognizer) -> Bool {
      let gesture = (gestureRecognizer as! UIPanGestureRecognizer)
      let direction = gesture.velocity(in: view).y

      let y = view.frame.minY
      if (y == fullView && tableView.contentOffset.y == 0 && direction > 0) || (y == partialView) {
          tableView.isScrollEnabled = false
      } else {
        tableView.isScrollEnabled = true
      }

      return false
  }

NOTE

In case you set .allowUserInteraction as an animation option, like in the sample project, so you need to enable scrolling on the animation completion closure if the user is scrolling up.

Sample Project

I created a sample project with more options on this repo which may give you better insights about how to customise the flow.

In the demo, addBottomSheetView() function controls which view should be used as a bottom sheet.

Sample Project Screenshots

- Partial View

- FullView

- Scrollable View

This can also be achieved with jsp:include. Chad Darby explains well here in this video https://www.youtube.com/watch?v=EWbYj0qoNHo

I had the same problem in docker and these steps worked for me:

apt update

then:

apt install libsm6 libxext6 libxrender-dev

Daemon threads are threads that run in the background as long as other non-daemon threads of the process are still running. Thus, when all of the non-daemon threads complete, the daemon threads are terminated. An example for the non-daemon thread is the thread running the Main. A thread is made daemon by calling the setDaemon() method before the thread is started

For More Reference : Daemon thread in Java

You can just create an object like this:

public class SomeQuery
{
    public string SomeParameter { get; set; }
    public int? SomeParameter2 { get; set; }
}

And then in controller just make something like that:

[HttpGet]
public IActionResult FindSomething([FromQuery] SomeQuery query)
{
    // Your implementation goes here..
}

Even better, you can create API model from:

[HttpGet]
public IActionResult GetSomething([FromRoute] int someId, [FromQuery] SomeQuery query)

to:

[HttpGet]
public IActionResult GetSomething(ApiModel model)

public class ApiModel
{
    [FromRoute]
    public int SomeId { get; set; }
    [FromQuery]
    public string SomeParameter { get; set; }
    [FromQuery]
    public int? SomeParameter2 { get; set; }
}

I had same problem in the render() method. The problem comes when you return from render() as :

render() {
    return 
    (
        <div>Here comes JSX !</div>
    );
}

i.e. if you start the parenthesis in a new line

Try using:

render() {
    return (
        <div>Here comes JSX !</div>
    );
}

This will solve the error

Could you provide a whole makefile? But right now I can tell - you should check that "install" target already exists. So, check Makefile whether it contains a

install: (anything there)

line. If not, there is no such target and so make has right. Probably you should use just "make" command to compile and then use it as is or install yourself, manually.

Install is not any standard of make, it is just a common target, that could exists, but not necessary.

It is more Ruby-like to ask objects whether they respond to a method you need or not, using respond_to?. This allows both minimal interface and implementation unaware programming.

It is not always applicable of course, thus there is still a possibility to ask about more conservative understanding of "type", which is class or a base class, using the methods you're asking about.

I think you should use prop(), if you are using jQuery 1.6 onwards.

To check it you should do:

$('#test').prop('checked', true);

to uncheck it:

$('#test').prop('checked', false);

There is no documented LEFT() function in Oracle. Find the full set here.

Probably what you have is a user-defined function. You can check that easily enough by querying the data dictionary:

select * from all_objects
where object_name = 'LEFT'

But there is the question of why the stored procedure works and the query doesn't. One possible solution is that the stored procedure is owned by another schema, which also owns the LEFT() function. They have granted rights on the procedure but not its dependencies. This works because stored procedures run with DEFINER privileges by default, so you run the stored procedure as if you were its owner.

If this is so then the data dictionary query I listed above won't help you: it will only return rows for objects you have rights on. In which case you will need to run the query as the stored procedure's owner or connect as a user with the rights to query DBA_OBJECTS instead.

Setting Up the database

public class DatabaseHelper extends SQLiteOpenHelper {
    // Database Version
    private static final int DATABASE_VERSION = 1;

    // Database Name
    private static final String DATABASE_NAME = "database_name";

    // Table Names
    private static final String DB_TABLE = "table_image";

    // column names
    private static final String KEY_NAME = "image_name";
    private static final String KEY_IMAGE = "image_data";

    // Table create statement
    private static final String CREATE_TABLE_IMAGE = "CREATE TABLE " + DB_TABLE + "("+ 
                       KEY_NAME + " TEXT," + 
                       KEY_IMAGE + " BLOB);";

    public DatabaseHelper(Context context) {
        super(context, DATABASE_NAME, null, DATABASE_VERSION);
    }

    @Override
    public void onCreate(SQLiteDatabase db) {

        // creating table
        db.execSQL(CREATE_TABLE_IMAGE);
    }

    @Override
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
        // on upgrade drop older tables
        db.execSQL("DROP TABLE IF EXISTS " + DB_TABLE);

        // create new table
        onCreate(db);
    }
}

Insert in the Database:

public void addEntry( String name, byte[] image) throws SQLiteException{
    SQLiteDatabase database = this.getWritableDatabase();
    ContentValues cv = new  ContentValues();
    cv.put(KEY_NAME,    name);
    cv.put(KEY_IMAGE,   image);
    database.insert( DB_TABLE, null, cv );
}

Retrieving data:

 byte[] image = cursor.getBlob(1);

Note:

1. Before inserting into database, you need to convert your Bitmap image into byte array first then apply it using database query.
2. When retrieving from database, you certainly have a byte array of image, what you need to do is to convert byte array back to original image. So, you have to make use of BitmapFactory to decode.

Below is an Utility class which I hope could help you:

public class DbBitmapUtility {

    // convert from bitmap to byte array
    public static byte[] getBytes(Bitmap bitmap) {
        ByteArrayOutputStream stream = new ByteArrayOutputStream();
        bitmap.compress(CompressFormat.PNG, 0, stream);
        return stream.toByteArray();
    }

    // convert from byte array to bitmap
    public static Bitmap getImage(byte[] image) {
        return BitmapFactory.decodeByteArray(image, 0, image.length);
    }
}

                    completion()
                })
            }
        }
    }

}

Usage

DispatchQueue.background(delay: 3.0, background: {
    // do something in background
}, completion: {
    // when background job finishes, wait 3 seconds and do something in main thread
})

DispatchQueue.background(background: {
    // do something in background
}, completion:{
    // when background job finished, do something in main thread
})

DispatchQueue.background(delay: 3.0, completion:{
    // do something in main thread after 3 seconds
})

Simplified example (with counter):

With Me.lstbox
    .ColumnCount = 2
    .ColumnWidths = "60;60"
    .AddItem
    .List(i, 0) = Company_ID
    .List(i, 1) = Company_name 
    i = i + 1

end with

Make sure to start the counter with 0, not 1 to fill up a listbox.

ECMAScript 6 introduced the let statement. You can use it in a for statement.

var ids:string = [];

for(let result of this.results){
   ids.push(result.Id);
}

I don't know if I'd call it production-ready, but there's jGABL.

There isn’t a pure JavaScript generic solution, I’m afraid. JavaScript isn’t able to turn off the CSS :hover state itself.

You could try the following alternative workaround though. If you don’t mind mucking about in your HTML and CSS a little bit, it saves you having to reset every CSS property manually via JavaScript.

HTML

<body class="nojQuery">

CSS

/* Limit the hover styles in your CSS so that they only apply when the nojQuery 
class is present */

body.nojQuery ul#mainFilter a:hover {
    /* CSS-only hover styles go here */
}

JavaScript

// When jQuery kicks in, remove the nojQuery class from the <body> element, thus
// making the CSS hover styles disappear.

$(function(){}
    $('body').removeClass('nojQuery');
)

I completely disagree with everyone who says OP is correct or there is no harm.

Everyone is talking about a modern and/or legacy OS's.

But what if I'm in an environment where I simply have no OS? Where there isn't anything?

Imagine now you are using thread styled interrupts and allocate memory. In the C standard ISO/IEC:9899 is the lifetime of memory stated as:

7.20.3 Memory management functions

1 The order and contiguity of storage allocated by successive calls to the calloc, malloc, and realloc functions is unspecified. The pointer returned if the allocation succeeds is suitably aligned so that it may be assigned to a pointer to any type of object and then used to access such an object or an array of such objects in the space allocated (until the space is explicitly deallocated). The lifetime of an allocated object extends from the allocation until the deallocation.[...]

So it has not to be given that the environment is doing the freeing job for you. Otherwise it would be added to the last sentence: "Or until the program terminates."

So in other words: Not freeing memory is not just bad practice. It produces non portable and not C conform code. Which can at least be seen as 'correct, if the following: [...], is supported by environment'.

But in cases where you have no OS at all, no one is doing the job for you (I know generally you don't allocate and reallocate memory on embedded systems, but there are cases where you may want to.)

So speaking in general plain C (as which the OP is tagged), this is simply producing erroneous and non portable code.

Place your content within a flexbox container that is 100% high i.e h-100. Then justify the content centrally by using justify-content-center class.

<section class="container h-100 d-flex justify-content-center">
    <div class="jumbotron my-auto">
        <h1 class="display-3">Hello, Malawi!</h1>
    </div>
</section>

None of the answers mentioned that the ToString() method can be applied to integer expressions

Debug.Assert((1000*1000).ToString()=="1000000");

even to integer literals

Debug.Assert(256.ToString("X")=="100");

Although integer literals like this are often considered to be bad coding style (magic numbers) there may be cases where this feature is useful...

R = HexToR("#FFFFFF");
G = HexToG("#FFFFFF");
B = HexToB("#FFFFFF");

function HexToR(h) {return parseInt((cutHex(h)).substring(0,2),16)}
function HexToG(h) {return parseInt((cutHex(h)).substring(2,4),16)}
function HexToB(h) {return parseInt((cutHex(h)).substring(4,6),16)}
function cutHex(h) {return (h.charAt(0)=="#") ? h.substring(1,7):h}

Use these Function to achive the result without any issue. :)

You can use online converter, developed by me at N'counter.

This is the easiest way to open SPSS file in Excel.

1) You just have to upload your file to SPSS coN'verter at https://secure.ncounter.de/SpssConverter

2) Select some options

3) And your converted Excel file will be downloaded

No information about your file contents is retained on our server. The file travels to our server, is converted in-memory, and is immediately discarded: We don't peer into your data at any time!

If you're using jQuery 2.1.4 or above, try this:

$("#" + this.d);

Or, you can define var before using it. It makes your code simpler.

var d = this.d
$("#" + d);

you will see your current bootstrap version in this "bootstrap.min.css/bootstrap.css" files, In the top section

In your CSS:

.image123{
float:left;
}

Try the following:

print "First is: %f" % (first)
print "Second is: %f" % (second)

I am unsure what answer is. But apart from that, this will be:

print "DONE: %f DIVIDED BY %f EQUALS %f, SWEET MATH BRO!" % (first, second, ans)

There's a lot of text on Format String Specifiers. You can google it and get a list of specifiers. One thing I forgot to note:

If you try this:

print "First is: %s" % (first)

It converts the float value in first to a string. So that would work as well.

What is also useful, if you use it for Machine_learning and want to seperate always the same data, you could use:

df.sample(n=len(df), random_state=42)

this makes sure, that you keep your random choice always replicatable

using(SqlDataReader rdr = cmd.ExecuteReader())
{
    while (rdr.Read())
    {
        var myString = rdr.GetString(0); //The 0 stands for "the 0'th column", so the first column of the result.
        // Do somthing with this rows string, for example to put them in to a list
        listDeclaredElsewhere.Add(myString);
    }
}

def test():
    ....
    return r1, r2, r3, ....

>> ret_val = test()
>> print ret_val
(r1, r2, r3, ....)

now you can do everything you like with your tuple.

I wrestled with this for some time. The problem lies not in how to load the data, but how to construct the table to hold it. You must generate a DDL statement to build the table before importing the data.

Particularly difficult if the table has a large number of columns.

Here's a python script that (almost) does the job:

#!/usr/bin/python    
import sys
import csv

# get file name (and hence table name) from command line
# exit with usage if no suitable argument   
if len(sys.argv) < 2:
   sys.exit('Usage: ' + sys.argv[0] + ': input CSV filename')
ifile = sys.argv[1]

# emit the standard invocation
print 'create table ' + ifile + ' ('

with open(ifile + '.csv') as inputfile:
   reader = csv.DictReader(inputfile)
   for row in reader:
      k = row.keys()
      for item in k:
         print '`' + item + '` TEXT,'
      break
   print ')\n'

The problem it leaves to solve is that the final field name and data type declaration is terminated with a comma, and the mySQL parser won't tolerate that.

Of course it also has the problem that it uses the TEXT data type for every field. If the table has several hundred columns, then VARCHAR(64) will make the table too large.

This also seems to break at the maximum column count for mySQL. That's when it's time to move to Hive or HBase if you are able.

You can extend jQuery functionalities like this:

jQuery.fn.extend({
scrollToMe: function () {
    var x = jQuery(this).offset().top - 100;
    jQuery('html,body').animate({scrollTop: x}, 500);
}});

and then:

$('...').scrollToMe();

easy ;-)

The error transformed in: fatal: protocol error: bad line length character: fata

after adding the location of git-upload-pack to the system path.

The problem seem to be an apostrophe added around the repository name: Looking with a tool like Process Monitor (from sys internals), that were added by the git client. It seems to be a git specific windows problem.

I tried the same command line in the prompt of the server: the full error was "fatal: not a given repository (or any of the parent directories): .git"

In conclusion, to me it seems like a software bug. Be advised that I am not a git expert, it is first time I use git, i come from subversion and perforce.

The answers provided (at the time of this post) are link only answers so I thought I would summarize the links into an answer and what I will be using.

When working to create Cross Browser Favicons (including touch icons) there are several things to consider.

The first (of course) is Internet Explorer. IE does not support PNG favicons until version 11. So our first line is a conditional comment for favicons in IE 9 and below:

<!--[if IE]><link rel="shortcut icon" href="path/to/favicon.ico"><![endif]-->

To cover the uses of the icon create it at 32x32 pixels. Notice the rel="shortcut icon" for IE to recognize the icon it needs the word shortcut which is not standard. Also we wrap the .ico favicon in a IE conditional comment because Chrome and Safari will use the .ico file if it is present, despite other options available, not what we would like.

The above covers IE up to IE 9. IE 11 accepts PNG favicons, however, IE 10 does not. Also IE 10 does not read conditional comments thus IE 10 won't show a favicon. With IE 11 and Edge available I don't see IE 10 in widespread use, so I ignore this browser.

For the rest of the browsers we are going to use the standard way to cite a favicon:

<link rel="icon" href="path/to/favicon.png">

This icon should be 196x196 pixels in size to cover all devices that may use this icon.

To cover touch icons on mobile devices we are going to use Apple's proprietary way to cite a touch icon:

<link rel="apple-touch-icon-precomposed" href="apple-touch-icon-precomposed.png">

Using rel="apple-touch-icon-precomposed" will not apply the reflective shine when bookmarked on iOS. To have iOS apply the shine use rel="apple-touch-icon". This icon should be sized to 180x180 pixels as that is the current size recommend by Apple for the latest iPhones and iPads. I have read Blackberry will also use rel="apple-touch-icon-precomposed".

As a note: Chrome for Android states:

The apple-touch-* are deprecated, and will be supported only for a short time. (Written as of beta for m31 of Chrome).

Custom Tiles for IE 11+ on Windows 8.1+

IE 11+ on Windows 8.1+ does offer a way to create pinned tiles for your site.

Microsoft recommends creating a few tiles at the following size:

Small: 128 x 128

Medium: 270 x 270

Wide: 558 x 270

Large: 558 x 558

These should be transparent images as we will define a color background next.

Once these images are created you should create an xml file called browserconfig.xml with the following code:

<?xml version="1.0" encoding="utf-8"?>
<browserconfig>
  <msapplication>
    <tile>
      <square70x70logo src="images/smalltile.png"/>
      <square150x150logo src="images/mediumtile.png"/>
      <wide310x150logo src="images/widetile.png"/>
      <square310x310logo src="images/largetile.png"/>
      <TileColor>#009900</TileColor>
    </tile>
  </msapplication>
</browserconfig>

Save this xml file in the root of your site. When a site is pinned IE will look for this file. If you want to name the xml file something different or have it in a different location add this meta tag to the head:

<meta name="msapplication-config" content="path-to-browserconfig/custom-name.xml" />

For additional information on IE 11+ custom tiles and using the XML file visit Microsoft's website.

Putting it all together:

To put it all together the above code would look like this:

<!-- For IE 9 and below. ICO should be 32x32 pixels in size -->
<!--[if IE]><link rel="shortcut icon" href="path/to/favicon.ico"><![endif]-->

<!-- Touch Icons - iOS and Android 2.1+ 180x180 pixels in size. --> 
<link rel="apple-touch-icon-precomposed" href="apple-touch-icon-precomposed.png">

<!-- Firefox, Chrome, Safari, IE 11+ and Opera. 196x196 pixels in size. -->
<link rel="icon" href="path/to/favicon.png">

Windows Phone Live Tiles

If a user is using a Windows Phone they can pin a website to the start screen of their phone. Unfortunately, when they do this it displays a screenshot of your phone, not a favicon (not even the MS specific code referenced above). To make a "Live Tile" for Windows Phone Users for your website one must use the following code:

Here are detailed instructions from Microsoft but here is a synopsis:

Step 1

Create a square image for your website, to support hi-res screens create it at 768x768 pixels in size.

Step 2

Add a hidden overlay of this image. Here is example code from Microsoft:

<div id="TileOverlay" onclick="ToggleTileOverlay()" style='background-color: Highlight; height: 100%; width: 100%; top: 0px; left: 0px; position: fixed; color: black; visibility: hidden'>
  <img src="customtile.png" width="320" height="320" />
  <div style='margin-top: 40px'>
     Add text/graphic asking user to pin to start using the menu...
  </div>
</div>

Step 3

You then can add thew following line to add a pin to start link:

<a href="javascript:ToggleTileOverlay()">Pin this site to your start screen</a>

Microsoft recommends that you detect windows phone and only show that link to those users since it won't work for other users.

Step 4

Next you add some JS to toggle the overlay visibility

<script>
function ToggleTileOverlay() {
 var newVisibility =     (document.getElementById('TileOverlay').style.visibility == 'visible') ? 'hidden' : 'visible';
 document.getElementById('TileOverlay').style.visibility =    newVisibility;
}
</script>

Note on Sizes

I am using one size as every browser will scale down the image as necessary. I could add more HTML to specify multiple sizes if desired for those with a lower bandwidth but I am already compressing the PNG files heavily using TinyPNG and I find this unnecessary for my purposes. Also, according to philippe_b's answer Chrome and Firefox have bugs that cause the browser to load all sizes of icons. Using one large icon may be better than multiple smaller ones because of this.

You can delete the folder itself, as well as all its contents, using shutil.rmtree:

import shutil
shutil.rmtree('/path/to/folder')

shutil.rmtree(path, ignore_errors=False, onerror=None)

Delete an entire directory tree; path must point to a directory (but not a symbolic link to a directory). If ignore_errors is true, errors resulting from failed removals will be ignored; if false or omitted, such errors are handled by calling a handler specified by onerror or, if that is omitted, they raise an exception.

I would strongly recommend using a library like PHPMailer to send emails.
It's easier and handles most of the issues automatically for you.

Regarding displaying embedded (inline) images, here's what's on their documentation:

Inline Attachments

There is an additional way to add an attachment. If you want to make a HTML e-mail with images incorporated into the desk, it's necessary to attach the image and then link the tag to it. For example, if you add an image as inline attachment with the CID my-photo, you would access it within the HTML e-mail with <img src="cid:my-photo" alt="my-photo" />.

In detail, here is the function to add an inline attachment:

$mail->AddEmbeddedImage(filename, cid, name);
//By using this function with this example's value above, results in this code:
$mail->AddEmbeddedImage('my-photo.jpg', 'my-photo', 'my-photo.jpg ');

To give you a more complete example of how it would work:

<?php
require_once('../class.phpmailer.php');
$mail = new PHPMailer(true); // the true param means it will throw exceptions on     errors, which we need to catch

$mail->IsSMTP(); // telling the class to use SMTP

try {
  $mail->Host       = "mail.yourdomain.com"; // SMTP server
  $mail->Port       = 25;                    // set the SMTP port
  $mail->SetFrom('[email protected]', 'First Last');
  $mail->AddAddress('[email protected]', 'John Doe');
  $mail->Subject = 'PHPMailer Test';

  $mail->AddEmbeddedImage("rocks.png", "my-attach", "rocks.png");
  $mail->Body = 'Your <b>HTML</b> with an embedded Image: <img src="cid:my-attach"> Here is an image!';

  $mail->AddAttachment('something.zip'); // this is a regular attachment (Not inline)
  $mail->Send();
  echo "Message Sent OK<p></p>\n";
} catch (phpmailerException $e) {
  echo $e->errorMessage(); //Pretty error messages from PHPMailer
} catch (Exception $e) {
  echo $e->getMessage(); //Boring error messages from anything else!
}
?>

Edit:

Regarding your comment, you asked how to send HTML email with embedded images, so I gave you an example of how to do that.
The library I told you about can send emails using a lot of methods other than SMTP.
Take a look at the PHPMailer Example page for other examples.

One way or the other, if you don't want to send the email in the ways supported by the library, you can (should) still use the library to build the message, then you send it the way you want.

For example:

You can replace the line that send the email:

$mail->Send();

With this:

$mime_message = $mail->CreateBody(); //Retrieve the message content
echo $mime_message; // Echo it to the screen or send it using whatever method you want

Hope that helps. Let me know if you run into trouble using it.

Your state with dictionary update some key without losing other value

state = 
{   
    name:"mjpatel"  
    parsedFilter:
    {
      page:2,
      perPage:4,
      totalPages: 50,
    }
}

Solution is below

 let { parsedFilter } = this.state
 this.setState({
      parsedFilter: {
        ...this.state.parsedFilter,
        page: 5
      }
  });

here update value for key "page" with value 5

tl;dr the "standards" are a hodge-podge mess; it depends who you ask!

Overall, there appears to be no MIME type image/jpg. Yet, in practice, nearly all software handles image files named "*.jpg" just fine.
This particular topic is confusing because the varying association of file name extension associated to a MIME type depends which organization created the table of file name extensions to MIME types. In other words, file name extension .jpg could be many different things.

For example, here are three "complete lists" and one RFC that with varying JPEG Image format file name extensions and the associated MIME types.

• sitepoint.com mime-types-complete-list (archived)
  • .jfif, .jfif-tbnl, .jpe, .jpeg, .jpg ? image/jpeg
  • .jfif, .jpe, .jpeg, .jpg ? image/pjpeg
• freeformatter.com mime-types (archived)
  • .jpeg, .jpg ? image/jpeg
  • .jpeg, .jpg ? image/x-citrix-jpeg
  • .pjpeg ? image/pjpeg
• IANA "Media Types" (formerly known as MIME types) lists (archived)
  (this document lists "names", not "file name extensions")
  • jpg not mentioned
  • jpeg ? see RFC 2045 (no mention), see RFC 2046 ? image/jpeg¹³
  • JPEG ? video/JPEG
  • jpeg2000 ? video/jpeg2000
  • jpm ? image/jpm (JPEG 2000)
  • jpx ? image/jpx (JPEG 2000)
  • vnd.sealedmedia.softseal.jpg ? image/vnd.sealedmedia.softseal.jpg
• RFC 3745 MIME Type Registrations for JPEG 2000 (ISO/IEC 15444)
  • .jpg file extension not mentioned
  • .jpeg file extension not mentioned
  • .jp2, .jpg2 ? image/jp2 (JPEG 2000)⁹
  • .jpf, .jpx ? image/jpx (JPEG 2000 ISO-JPEG2000-2 encoded image data)¹⁰
  • .mj2, .mjp2 ? video/mj2 (Motion JPEG 2000)¹¹
  • .jpm, .jpgm ? image/jpm (JPEG 2000 profiles and extensions)¹²

These "complete lists" and RFC do not have MIME type image/jpg! But for MIME type image/jpeg some lists do have varying file name extensions (.jpeg, .jpg, …). Other lists do not mention image/jpeg.

Also, there are different types of JPEG Image formats (e.g. Progressive JPEG Image format, JPEG 2000, etcetera) and "JPEG Extensions" that may or may not overlap in file name extension and declared MIME type.

Another confusing thing is RFC 3745 does not appear to match IANA Media Types yet the same RFC is supposed to inform the IANA Media Types document. For example, in RFC 3745 .jpf is preferred file extension for image/jpx but in IANA Media Types the name jpf is not present (and that IANA document references RFC 3745!).

Another confusing thing is IANA Media Types lists "names" but does not list "file name extensions". This is on purpose, but confuses the endeavor of mapping file name extensions to MIME types.

Another confusing thing: is it "mime", or "MIME", or "MIME type", or "mime type", or "mime/type", or "media type"?

The most official seeming document by IANA is surprisingly inadequate. No MIME type is registered for file extension .jpg yet there exists the odd vnd.sealedmedia.softseal.jpg. File extension.JPEG is only known as a video type while file extension .jpeg is an image type (when did lowercase and uppercase letters start mattering!?). At the same time, jpeg2000 is type video yet RFC 3745 considers JPEG 2000 an image type! The IANA list seems to cater to company-specific jpeg formats (e.g. vnd.sealedmedia.softseal.jpg).

Because of the prior confusions, it is difficult to find an industry-accepted canonical document that maps file name extensions to MIME types, particularly for the JPEG Image File Format.

I like JSON mainly because it's so terse. For web content that can be gzipped, this isn't necessarily a big deal (hence why xhtml is so popular). But there are occasions where this can be beneficial.

For example, for one project I was transmitting information that needed to be serialized and transmitted via XMPP. Since most servers will limit the amount of data you can transmit in a single message, I found it helpful to use JSON over the obvious alternative, XML.

As an added bonus, if you're familiar with Python or Javascript, you already pretty much know JSON and can interpret it without much training at all.

No. In general Java doesn't have much (any) syntactic sugar, since they tried to make a simple language.

In case setting fixed height for the RecyclerView didn't work for someone (like me), here is what I've added to the fixed height solution:

mRecyclerView.addOnItemTouchListener(new RecyclerView.OnItemTouchListener() {
    @Override
    public boolean onInterceptTouchEvent(RecyclerView rv, MotionEvent e) {
        int action = e.getAction();
        switch (action) {
            case MotionEvent.ACTION_MOVE:
                rv.getParent().requestDisallowInterceptTouchEvent(true);
                break;
        }
        return false;
    }

    @Override
    public void onTouchEvent(RecyclerView rv, MotionEvent e) {

    }

    @Override
    public void onRequestDisallowInterceptTouchEvent(boolean disallowIntercept) {

    }
});

An elegant example without the need for a positioned wrapper or duplicative content in the markup:

:root {_x000D_
  background: #f2f2f2;_x000D_
}_x000D_
h1 {_x000D_
  background-color: #565656;_x000D_

  background-clip: text;_x000D_
}

<center>_x000D_
  <h1>Text With Inner Shadow</h1>_x000D_

Looks good on dark backgrounds as well:

What is the newline character in the C language: \r or \n?

The new-line may be thought of a some char and it has the value of '\n'. C11 5.2.1

This C new-line comes up in 3 places: C source code, as a single char and as an end-of-line in file I/O when in text mode.

1. Many compilers will treat source text as ASCII. In that case, codes 10, sometimes 13, and sometimes paired 13,10 as new-line for source code. Had the source code been in another character set, different codes may be used. This new-line typically marks the end of a line of source code (actually a bit more complicated here), // comment, and # directives.

2. In source code, the 2 characters \ and n represent the char new-line as \n. If ASCII is used, this char would have the value of 10.

3. In file I/O, in text mode, upon reading the bytes of the input file (and stdin), depending on the environment, when bytes with the value(s) of 10 (Unix), 13,10, (*1) (Windows), 13 (Old Mac??) and other variations are translated in to a '\n'. Upon writing a file (or stdout), the reverse translation occurs.
   Note: File I/O in binary mode makes no translation.

The '\r' in source code is the carriage return char.

(*1) A lone 13 and/or 10 may also translate into \n.

Add the following line in your .profile file in your home directory (using vi ~/.profile):

PATH=$PATH:/home/me/play
export PATH

Then, for the change to take effect, simply type in your terminal:

$ . ~/.profile

Had the same problem, thanks mikej.

In WLS 10.3 this configuration can be found in Services > JTA menu, or if you click on the domain name (first item in the menu) - on the Configuration > JTA tabs.

I faced this exact same issue with Laravel 8.x on Ubuntu 20. I run: sudo apt install php7.4-xml and composer update within the project directory. This fixed the issue.

os.Open() must have worked differently in the past, but this works for me:

f, err := os.OpenFile("testlogfile", os.O_RDWR | os.O_CREATE | os.O_APPEND, 0666)
if err != nil {
    log.Fatalf("error opening file: %v", err)
}
defer f.Close()

log.SetOutput(f)
log.Println("This is a test log entry")

Based on the Go docs, os.Open() can't work for log.SetOutput, because it opens the file "for reading:"

func Open

func Open(name string) (file *File, err error) Open opens the named file for reading. If successful, methods on the returned file can be used for reading; the associated file descriptor has mode O_RDONLY. If there is an error, it will be of type *PathError.

EDIT

Moved defer f.Close() to after if err != nil check

A language itself is neither compiled nor interpreted, only a specific implementation of a language is. Java is a perfect example. There is a bytecode-based platform (the JVM), a native compiler (gcj) and an interpeter for a superset of Java (bsh). So what is Java now? Bytecode-compiled, native-compiled or interpreted?

Other languages, which are compiled as well as interpreted, are Scala, Haskell or Ocaml. Each of these languages has an interactive interpreter, as well as a compiler to byte-code or native machine code.

So generally categorizing languages by "compiled" and "interpreted" doesn't make much sense.

This tutorial gives a simple, yet elegant, solution, which i transcribe:

#include <sstream>
#include <string>
#include <stdexcept>

class BadConversion : public std::runtime_error {
public:
  BadConversion(std::string const& s)
    : std::runtime_error(s)
    { }
};

inline std::string stringify(double x)
{
  std::ostringstream o;
  if (!(o << x))
    throw BadConversion("stringify(double)");
  return o.str();
}
...
std::string my_val = stringify(val);

http://momentjs.com/ or https://date-fns.org/

From Moment docs:

var a = moment([2007, 0, 29]);
var b = moment([2007, 0, 28]);
a.diff(b, 'days')   // =1

or to include the start:

a.diff(b, 'days')+1   // =2

Beats messing with timestamps and time zones manually.

Depending on your specific use case, you can either

1. Use a/b.startOf('day') and/or a/b.endOf('day') to force the diff to be inclusive or exclusive at the "ends" (as suggested by @kotpal in the comments).
2. Set third argument true to get a floating point diff which you can then Math.floor, Math.ceil or Math.round as needed.
3. Option 2 can also be accomplished by getting 'seconds' instead of 'days' and then dividing by 24*60*60.

Simplest way for create SSL certificate

Open Firefox (I suppose it's also possible with Chrome, but it's easier for me with FF)

Visit your development site with a self-signed SSL certificate.

Click on the certificate (next to the site name)

Click on "More information"

Click on "View certificate"

Click on "Details"

Click on "Export..."

Choose "X.509 Certificate whith chain (PEM)", select the folder and name to save it and click "Save"

Go to command line, to the directory where you downloaded the pem file and execute "openssl x509 -inform PEM -outform DM -in .pem -out .crt"

Copy the .crt file to the root of the /sdcard folder inside your Android device Inside your Android device, Settings > Security > Install from storage.

It should detect the certificate and let you add it to the device Browse to your development site.

The first time it should ask you to confirm the security exception. That's all.

The certificate should work with any browser installed on your Android (Browser, Chrome, Opera, Dolphin...)

Remember that if you're serving your static files from a different domain (we all are page speed bitches) you also need to add the certificate for that domain.

Why not just use, toggleClass on click?

js:

$(this).toggleClass("up");

css:

button.up {
    -webkit-transform: rotate(180deg);
       -moz-transform: rotate(180deg);
        -ms-transform: rotate(180deg);
         -o-transform: rotate(180deg);
            transform: rotate(180deg);
               /* IE6–IE9 */
               filter: progid:DXImageTransform.Microsoft.Matrix(M11=0.9914448613738104, M12=-0.13052619222005157,M21=0.13052619222005157, M22=0.9914448613738104, sizingMethod='auto expand');
                 zoom: 1;
    }

you can also add this to the css:

button{
        -webkit-transition: all 500ms ease-in-out;
        -moz-transition: all 500ms ease-in-out;
        -o-transition: all 500ms ease-in-out;
        -ms-transition: all 500ms ease-in-out;
}

which will add the animation.

PS...

to answer your original question:

you said that it rotates but never stops. When using set timeout you need to make sure you have a condition that will not call settimeout or else it will run forever. So for your code:

<script type="text/javascript">
    $(function() {
     var $elie = $("#bkgimg");
     rotate(0);
     function rotate(degree) {

      // For webkit browsers: e.g. Chrome
    $elie.css({ WebkitTransform: 'rotate(' + degree + 'deg)'});
      // For Mozilla browser: e.g. Firefox
    $elie.css({ '-moz-transform': 'rotate(' + degree + 'deg)'});


    /* add a condition here for the extremity */ 
    if(degree < 180){
      // Animate rotation with a recursive call
      setTimeout(function() { rotate(++degree); },65);
     }
    }
    });
    </script>

It happened with me, I used jquery.min.js file that downloaded from bootstrap site it is not working, I tried same page with other jquery.min.js file it worked fine so if you face this problem try to reference other jquery.min.js file in your page and try again

I assume that since you're using an XML declaration, you're not worrying about IE or older browsers.

So you can use display:table-cell and display:table-row like so:

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">

    <title></title>
    <style type="text/css">
        .toolbar ul {
            display:table-row;
        }
        .toolbar ul li
        {
            display: table-cell;
            height: 100px;
            list-style-type: none;
            margin: 10px;
            vertical-align: middle;
        }
        .toolbar ul li a {
            display:table-cell;
            vertical-align: middle;
            height:100px;
            border: solid 1px black;
        }
        .toolbar ul li.button a {
            height:50px;
            border: solid 1px black;
        }
    </style>
</head>
<body>
    <div class="toolbar">
        <ul>
            <li><a href="#">first item<br />
                first item<br />
                first item</a></li>
            <li><a href="#">second item</a></li>
            <li><a href="#">last item</a></li>
            <li class="button"><a href="#">button<br />
                button</a></li>
        </ul>
    </div>
</body>
</html>

Based on the manual page:

# Log in to the server.  This only needs to be done once.
wget --save-cookies cookies.txt \
     --keep-session-cookies \
     --post-data 'user=foo&password=bar' \
     --delete-after \
     http://server.com/auth.php

# Now grab the page or pages we care about.
wget --load-cookies cookies.txt \
     http://server.com/interesting/article.php

Make sure the --post-data parameter is properly percent-encoded (especially ampersands!) or the request will probably fail. Also make sure that user and password are the correct keys; you can find out the correct keys by sleuthing the HTML of the login page (look into your browser’s “inspect element” feature and find the name attribute on the username and password fields).

In case anyone would like to obtain meaningful orientation description (like that passed to onConfigurationChanged(..) with those reverseLandscape, sensorLandscape and so on), simply use getRequestedOrientation()

Your character class (the part in the square brackets) is saying that you want to match anything except 0-9 and a-z and +. You aren't explicit about how many a-z or 0-9 you want to match, but I assume the + means you want to replace strings of at least one alphanumeric character. It should read instead:

str = str.replace(/[^-a-z0-9]+/g, "");

Also, if you need to match upper-case letters along with lower case, you should use:

str = str.replace(/[^-a-zA-Z0-9]+/g, "");

In my limited experience I am coming across issues as well. It appears that JQuery elements (such as buttons) can be styled using bootstrap CSS. However, I am experiencing issues having created a JQuery UI tab and wanting to lock a bootstrap only input (using the input-append class) to the bottom of each tab, only the first sits correctly. So, JQuery tabs + Bootstrap buttons = probably not.

resize:none; This property fix your text area and bound it. you use this css property id your textarea.gave text area an id and on the behalf of that id you can use this css property.

you need to put a dot between the class like

class="column.wrapper">

The W3C doc doesn't use concepts like wrong and sin, but it does use those like provide the means, may be appropriate and discouraged.

Actually, in the second paragraph of section 4, the 4.01 spec itemizes its words as follows

The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [RFC2119]. However, for readability, these words do not appear in all uppercase letters in this specification.

With that in mind, I believe the definitive statement is in 7.5.3 Block-level and inline elements, where it says

Generally, inline elements may contain only data and other inline elements.

The condition "generally" appears to introduce enough ambiguity to say that HTML 4.01 does allow inline elements to contain block elements.

Certainly, CSS2 has a display property value, inline-block, that appears to be suited to the purpose you describe. I'm not sure if it was ever widely supported, but it seems that someone anticipated the need for that kind of behavior.

The DTD appear to be less forgiving here, but the text of the DTD defers to the spec:

The HTML 4.01 specification includes additional syntactic constraints that cannot be expressed within the DTDs.

In another comment, you suggest that you want to make a block active by wrapping it in an anchor. I don't believe HTML prohibits that, and CSS clearly allows it. So to answer the title question about whether it is ever correct, I say yes. By the standards, it is sometimes correct.

Another way (Using Formulas in VBA). I guess this is the shortest VBA code as well?

Sub Sample()
    Dim ws As Worksheet
    Dim lRow As Long

    Set ws = ThisWorkbook.Sheets("Sheet1")

    With ws
        lRow = .Range("A" & .Rows.Count).End(xlUp).Row

        .Range("B1:B" & lRow).Formula = "=If(A1<>"""",""My Text"","""")"
        .Range("B1:B" & lRow).Value = .Range("B1:B" & lRow).Value
    End With
End Sub

To get the route segments:

import { ActivatedRoute, UrlSegment } from '@angular/router';

constructor( route: ActivatedRoute) {}

getRoutes() { const segments: UrlSegment[] = this.route.snapshot.url; }

Let's try this

select convert(varchar, getdate(), 108) 

Just try a few moment ago

Despite the many answers, one more approach which uses prop.table in combination with dplyr or data.table.

library("dplyr")
mtcars %>%
    group_by(am, gear) %>%
    summarise(n = n()) %>%
    mutate(freq = prop.table(n))

library("data.table")
cars_dt <- as.data.table(mtcars)
cars_dt[, .(n = .N), keyby = .(am, gear)][, freq := prop.table(n) , by = "am"]

Here's how you can do custom naming

import pyspark
from pyspark.sql import functions as sf
sc = pyspark.SparkContext()
sqlc = pyspark.SQLContext(sc)
df = sqlc.createDataFrame([('row11','row12'), ('row21','row22')], ['colname1', 'colname2'])
df.show()

gives,

+--------+--------+
|colname1|colname2|
+--------+--------+
|   row11|   row12|
|   row21|   row22|
+--------+--------+

create new column by concatenating:

df = df.withColumn('joined_column', 
                    sf.concat(sf.col('colname1'),sf.lit('_'), sf.col('colname2')))
df.show()

+--------+--------+-------------+
|colname1|colname2|joined_column|
+--------+--------+-------------+
|   row11|   row12|  row11_row12|
|   row21|   row22|  row21_row22|
+--------+--------+-------------+
