My way is importing the jquery library.

I had this concern when working on a Rails application with Docker.

My most preferred approach is to generally not use quotes. This includes not using quotes for:

• variables like ${RAILS_ENV}
• values separated by a colon (:) like postgres-log:/var/log/postgresql
• other strings values

I, however, use double-quotes for integer values that need to be converted to strings like:

• docker-compose version like version: "3.8"
• port numbers like "8080:8080"

However, for special cases like booleans, floats, integers, and other cases, where using double-quotes for the entry values could be interpreted as strings, please do not use double-quotes.

Here's a sample docker-compose.yml file to explain this concept:

version: "3"

services:
  traefik:
    image: traefik:v2.2.1
    command:
      - --api.insecure=true # Don't do that in production
      - --providers.docker=true
      - --providers.docker.exposedbydefault=false
      - --entrypoints.web.address=:80
    ports:
      - "80:80"
      - "8080:8080"
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock:ro

That's all.

I hope this helps

I'm new to both Python and PyQt5. I tried to use pip, but I was having problems with it using a Windows machine. If you have a version of Python 3.4 or above, pip is installed and ready to use like so:

python -m pip install pyqt5 

That's of course assuming that the path for Python executable is in your PATH environment variable. Otherwise include the full path to Python executable (you can type where python to the Command Window to find it) like:

C:\users\userName\AppData\Local\Programs\Python\Python34\python.exe -m pip install pyqt5

git stash show -p | git apply --reverse

Warning, that would not in every case: "git apply -R"^(man) did not handle patches that touch the same path twice correctly, which has been corrected with Git 2.30 (Q1 2021).

This is most relevant in a patch that changes a path from a regular file to a symbolic link (and vice versa).

See commit b0f266d (20 Oct 2020) by Jonathan Tan (jhowtan).
^{(Merged by Junio C Hamano -- gitster -- in commit c23cd78, 02 Nov 2020)}

apply: when -R, also reverse list of sections

^{Helped-by: Junio C Hamano
Signed-off-by: Jonathan Tan}

A patch changing a symlink into a file is written with 2 sections (in the code, represented as "struct patch"): firstly, the deletion of the symlink, and secondly, the creation of the file.

When applying that patch with -R, the sections are reversed, so we get: (1) creation of a symlink, then (2) deletion of a file.

This causes an issue when the "deletion of a file" section is checked, because Git observes that the so-called file is not a file but a symlink, resulting in a "wrong type" error message.

What we want is: (1) deletion of a file, then (2) creation of a symlink.

In the code, this is reflected in the behavior of previous_patch() when invoked from check_preimage() when the deletion is checked.
Creation then deletion means that when the deletion is checked, previous_patch() returns the creation section, triggering a mode conflict resulting in the "wrong type" error message.

But deletion then creation means that when the deletion is checked, previous_patch() returns NULL, so the deletion mode is checked against lstat, which is what we want.

There are also other ways a patch can contain 2 sections referencing the same file, for example, in 7a07841c0b ("git-apply: handle a patch that touches the same path more than once better", 2008-06-27, Git v1.6.0-rc0 -- merge). "git apply -R"^(man) fails in the same way, and this commit makes this case succeed.

Therefore, when building the list of sections, build them in reverse order (by adding to the front of the list instead of the back) when -R is passed.

The primary key in Cassandra usually consists of two parts - Partition key and Clustering columns.

primary_key((partition_key), clustering_col )

Partition key - The first part of the primary key. The main aim of a partition key is to identify the node which stores the particular row.

CREATE TABLE phone_book ( phone_num int, name text, age int, city text, PRIMARY KEY ((phone_num, name), age);

Here, (phone_num, name) is the partition key. While inserting the data, the hash value of the partition key is generated and this value decides which node the row should go into.

Consider a 4 node cluster, each node has a range of hash values it can store. (Write) INSERT INTO phone_book VALUES (7826573732, ‘Joey’, 25, ‘New York’);

Now, the hash value of the partition key is calculated by Cassandra partitioner. say, hash value(7826573732, ‘Joey’) ? 12 , now, this row will be inserted in Node C.

(Read) SELECT * FROM phone_book WHERE phone_num=7826573732 and name=’Joey’;

Now, again the hash value of the partition key (7826573732,’Joey’) is calculated, which is 12 in our case which resides in Node C, from which the read is done.

2. Clustering columns - Second part of the primary key. The main purpose of having clustering columns is to store the data in a sorted order. By default, the order is ascending.

There can be more than one partition key and clustering columns in a primary key depending on the query you are solving.

primary_key((pk1, pk2), col 1,col2)

You don't even have to set a specific width for the cells, table-layout: fixed suffices to spread the cells evenly.

ul {_x000D_
    width: 100%;_x000D_
    display: table;_x000D_
    table-layout: fixed;_x000D_
    border-collapse: collapse;_x000D_
}_x000D_
li {_x000D_
    display: table-cell;_x000D_
    text-align: center;_x000D_
    border: 1px solid hotpink;_x000D_
    vertical-align: middle;_x000D_
    word-wrap: break-word;_x000D_
}

<ul>_x000D_
  <li>foo<br>foo</li>_x000D_
  <li>barbarbarbarbar</li>_x000D_
  <li>baz</li>_x000D_
</ul>

Note that for table-layout to work the table styled element must have a width set (100% in my example).

Swift 4

Add a view outlet

@IBOutlet weak var gradientView: UIView!

Add gradient to the view

func setGradient() {
    let gradient: CAGradientLayer = CAGradientLayer()
    gradient.colors = [UIColor.red.cgColor, UIColor.blue.cgColor]
    gradient.locations = [0.0 , 1.0]
    gradient.startPoint = CGPoint(x: 0.0, y: 1.0)
    gradient.endPoint = CGPoint(x: 1.0, y: 1.0)
    gradient.frame = gradientView.layer.frame
    gradientView.layer.insertSublayer(gradient, at: 0)
}

Some browsers such as Firefox, Chrome, Safari, Opera and IE10+ can handle Base64 natively. Take a look at this Stackoverflow question. It's using btoa() and atob() functions.

For server-side JavaScript (Node), you can use Buffers to decode.

If you are going for a cross-browser solution, there are existing libraries like CryptoJS or code like:

http://ntt.cc/2008/01/19/base64-encoder-decoder-with-javascript.html

With the latter, you need to thoroughly test the function for cross browser compatibility. And error has already been reported.

One additional suggestion to be explicit. It seems best to go from specific to general down the stack of errors to get the desired error to be caught, so the specific ones don't get masked by the general one.

This will give you the difference between two dates, in milliseconds

var diff = Math.abs(date1 - date2);

In your example, it'd be

var diff = Math.abs(new Date() - compareDate);

You need to make sure that compareDate is a valid Date object.

Something like this will probably work for you

var diff = Math.abs(new Date() - new Date(dateStr.replace(/-/g,'/')));

i.e. turning "2011-02-07 15:13:06" into new Date('2011/02/07 15:13:06'), which is a format the Date constructor can comprehend.

My problem did not go away with just reinstalling the 2015 vc redistributables. But I was able to find the error using the same process as in the excellent blog post by Ezh (and thanks to Google Translate for making me able to read it).

In my case it was msvcp140.dll that was installed as a 64bit version in the Windows/SysWOW64 folder. Just uninstalling the redistributables did not remove the file, so I had to delete it manually. Then I was able to install the x86 redistributables again, which installed a correct version of the dll file. And, voilà, the installation of VS2015 finished without errors.

Before each of your conditional statements, you could do something like this:

var pagetype = pagetype || false;
if (pagetype === 'something') {
    //do stuff
}

For an inner join, WHERE and ON can be used interchangeably. In fact, it's possible to use ON in a correlated subquery. For example:

update mytable
set myscore=100
where exists (
select 1 from table1
inner join table2
on (table2.key = mytable.key)
inner join table3
on (table3.key = table2.key and table3.key = table1.key)
...
)

This is (IMHO) utterly confusing to a human, and it's very easy to forget to link table1 to anything (because the "driver" table doesn't have an "on" clause), but it's legal.

SVG

Would recommend using svg for graphical elements. While using css to style your elements.

#box {_x000D_
  fill: orange;_x000D_
  stroke: black;_x000D_
}

<svg>_x000D_
  <rect id="box" x="0" y="0" width="50" height="50"/>_x000D_
</svg>

^[a-zA-Z] means any a-z or A-Z at the start of a line

[^a-zA-Z] means any character that IS NOT a-z OR A-Z

For quick reference along with clear concise examples, Allen Holub's UML Quick Reference is excellent:

http://www.holub.com/goodies/uml/

(There are quite a few specific examples of arrows and pointers in the first column of a table, with descriptions in the second column.)

One usual solution is to wrap your function foo with a decorator like

result = queue.Queue()

def task_wrapper(*args):
    result.put(target(*args))

Then the whole code may looks like that

result = queue.Queue()

def task_wrapper(*args):
    result.put(target(*args))

threads = [threading.Thread(target=task_wrapper, args=args) for args in args_list]

for t in threads:
    t.start()
    while(True):
        if(len(threading.enumerate()) < max_num):
            break
for t in threads:
    t.join()
return result

Note

One important issue is that the return values may be unorderred. (In fact, the return value is not necessarily saved to the queue, since you can choose arbitrary thread-safe data structure )

This worked for me.

// strip tags to avoid breaking any html
$string = strip_tags($string);
if (strlen($string) > 500) {

    // truncate string
    $stringCut = substr($string, 0, 500);
    $endPoint = strrpos($stringCut, ' ');

    //if the string doesn't contain any space then it will cut without word basis.
    $string = $endPoint? substr($stringCut, 0, $endPoint) : substr($stringCut, 0);
    $string .= '... <a href="/this/story">Read More</a>';
}
echo $string;

Not sure about IE9, but Opera doesn’t seem to have any gradient support yet:

• http://www.opera.com/docs/specs/presto26/#css

No occurrence of “gradient” on that page.

There’s a great article by Robert Nyman on getting CSS gradients working in all browsers that aren’t Opera though:

• http://robertnyman.com/2010/02/15/css-gradients-for-all-web-browsers-without-using-images/

Not sure if that can be extended to use an image as a fallback.

implode():

<?php
$string = implode('|',$types);

However, Incognito is right, you probably don't want to store it that way -- it's a total waste of the relational power of your database.

If you're dead-set on serializing, you might also consider using json_encode()

There is no bound checking in array in C programming. If you declare array as

int arr[50];

Then you can even write as

arr[51] = 10;

The compiler would not throw an error. Hope this answers your question.

Editing Windows registries is not worth it and not safe, use Map network drive and load the network share as if it's loaded from one of your local drives.

A convenient function for saving plots is ggsave(), which can automatically guess the device type based on the file extension, and smooths over differences between devices. You save with a certain size and units like this:

ggsave("mtcars.png", width = 20, height = 20, units = "cm")

In R markdown, figure size can be specified by chunk:

```{r, fig.width=6, fig.height=4}  
plot(1:5)
```

In Swift 4.2 and Xcode 9.4.1

Add Animation delegate, CAAnimationDelegate to your class

//Swipe gesture for left and right
let swipeFromRight = UISwipeGestureRecognizer(target: self, action: #selector(didSwipeLeft))
swipeFromRight.direction = UISwipeGestureRecognizerDirection.left
menuTransparentView.addGestureRecognizer(swipeFromRight)

let swipeFromLeft = UISwipeGestureRecognizer(target: self, action: #selector(didSwipeRight))
swipeFromLeft.direction = UISwipeGestureRecognizerDirection.right
menuTransparentView.addGestureRecognizer(swipeFromLeft)

//Swipe gesture selector function
@objc func didSwipeLeft(gesture: UIGestureRecognizer) {
    //We can add some animation also
    DispatchQueue.main.async(execute: {
            let animation = CATransition()
            animation.type = kCATransitionReveal
            animation.subtype = kCATransitionFromRight
            animation.duration = 0.5
            animation.delegate = self
            animation.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseInEaseOut)
            //Add this animation to your view
            self.transparentView.layer.add(animation, forKey: nil)
            self.transparentView.removeFromSuperview()//Remove or hide your view if requirement.
        })
}

//Swipe gesture selector function
@objc func didSwipeRight(gesture: UIGestureRecognizer) {
        // Add animation here
        DispatchQueue.main.async(execute: {
            let animation = CATransition()
            animation.type = kCATransitionReveal
            animation.subtype = kCATransitionFromLeft
            animation.duration = 0.5
            animation.delegate = self
            animation.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseInEaseOut)
            //Add this animation to your view
            self.transparentView.layer.add(animation, forKey: nil)
            self.transparentView.removeFromSuperview()//Remove or hide yourview if requirement.
        })
}

If you want to remove gesture from view use this code

self.transparentView.removeGestureRecognizer(gesture)

Ex:

func willMoveFromView(view: UIView) {
    if view.gestureRecognizers != nil {
        for gesture in view.gestureRecognizers! {
            //view.removeGestureRecognizer(gesture)//This will remove all gestures including tap etc...
            if let recognizer = gesture as? UISwipeGestureRecognizer {
                //view.removeGestureRecognizer(recognizer)//This will remove all swipe gestures
                if recognizer.direction == .left {//Especially for left swipe
                    view.removeGestureRecognizer(recognizer)
                }
            }
        }
    }
}

Call this function like

//Remove swipe gesture
self.willMoveFromView(view: self.transparentView)

Like this you can write remaining directions and please careful whether if you have scroll view or not from bottom to top and vice versa

If you have scroll view, you will get conflict for Top to bottom and view versa gestures.

Why don't you just use the array of chars you have? This ought to do it:

   source[i] = getc(fp); 
   i++;

I use coldfusion 8 on JDK 1.6.45 and had problems with giving me just red crosses instead of images, and also with cfhttp not able to connect to the local webserver with ssl.

my test script to reproduce with coldfusion 8 was

<CFHTTP URL="https://www.onlineumfragen.com" METHOD="get" ></CFHTTP>
<CFDUMP VAR="#CFHTTP#">

this gave me the quite generic error of " I/O Exception: peer not authenticated." I then tried to add certificates of the server including root and intermediate certificates to the java keystore and also the coldfusion keystore, but nothing helped. then I debugged the problem with

java SSLPoke www.onlineumfragen.com 443

and got

javax.net.ssl.SSLException: java.lang.RuntimeException: Could not generate DH keypair

and

Caused by: java.security.InvalidAlgorithmParameterException: Prime size must be
multiple of 64, and can only range from 512 to 1024 (inclusive)
    at com.sun.crypto.provider.DHKeyPairGenerator.initialize(DashoA13*..)
    at java.security.KeyPairGenerator$Delegate.initialize(KeyPairGenerator.java:627)
    at com.sun.net.ssl.internal.ssl.DHCrypt.<init>(DHCrypt.java:107)
    ... 10 more

I then had the idea that the webserver (apache in my case) had very modern ciphers for ssl and is quite restrictive (qualys score a+) and uses strong diffie hellmann keys with more than 1024 bits. obviously, coldfusion and java jdk 1.6.45 can not manage this. Next step in the odysee was to think of installing an alternative security provider for java, and I decided for bouncy castle. see also http://www.itcsolutions.eu/2011/08/22/how-to-use-bouncy-castle-cryptographic-api-in-netbeans-or-eclipse-for-java-jse-projects/

I then downloaded the

bcprov-ext-jdk15on-156.jar

from http://www.bouncycastle.org/latest_releases.html and installed it under C:\jdk6_45\jre\lib\ext or where ever your jdk is, in original install of coldfusion 8 it would be under C:\JRun4\jre\lib\ext but I use a newer jdk (1.6.45) located outside the coldfusion directory. it is very important to put the bcprov-ext-jdk15on-156.jar in the \ext directory (this cost me about two hours and some hair ;-) then I edited the file C:\jdk6_45\jre\lib\security\java.security (with wordpad not with editor.exe!) and put in one line for the new provider. afterwards the list looked like

#
# List of providers and their preference orders (see above):
#
security.provider.1=org.bouncycastle.jce.provider.BouncyCastleProvider
security.provider.2=sun.security.provider.Sun
security.provider.3=sun.security.rsa.SunRsaSign
security.provider.4=com.sun.net.ssl.internal.ssl.Provider
security.provider.5=com.sun.crypto.provider.SunJCE
security.provider.6=sun.security.jgss.SunProvider
security.provider.7=com.sun.security.sasl.Provider
security.provider.8=org.jcp.xml.dsig.internal.dom.XMLDSigRI
security.provider.9=sun.security.smartcardio.SunPCSC
security.provider.10=sun.security.mscapi.SunMSCAPI

(see the new one in position 1)

then restart coldfusion service completely. you can then

java SSLPoke www.onlineumfragen.com 443 (or of course your url!)

and enjoy the feeling... and of course

what a night and what a day. Hopefully this will help (partially or fully) to someone out there. if you have questions, just mail me at info ... (domain above).

Java documentation for java.net.BindExcpetion,

Signals that an error occurred while attempting to bind a socket to a local address and port. Typically, the port is in use, or the requested local address could not be assigned.

Cause:

The error is due to the second condition mentioned above. When you start a server(Tomcat,Jetty etc) it listens to a port and bind a socket to an address and port. In Windows and Linux the hostname is resolved to IP address from /etc/hosts This host to IP address mapping file can be found at C:\Windows\System32\Drivers\etc\hosts. If this mapping is changed and the host name cannot be resolved to the IP address you get the error message.

Solution:

Edit the hosts file and correct the mapping for hostname and IP using admin privileges.

eg:

#127.0.0.1 localhost
192.168.52.1 localhost

Read more: java.net.BindException : cannot assign requested address.

Try GRANT ADMINISTER BULK OPERATIONS TO [server_login]. It is a server level permission, not a database level. This has fixed a similar issue for me in that past (using OPENROWSET I believe).

.hide() stores the previous display property just before setting it to none, so if it wasn't the standard display property for the element you're a bit safer, .show() will use that stored property as what to go back to. So...it does some extra work, but unless you're doing tons of elements, the speed difference should be negligible.

You aren't actually sending JSON. You are passing an object as the data, but you need to stringify the object and pass the string instead.

Your dataType: "json" only tells jQuery that you want it to parse the returned JSON, it does not mean that jQuery will automatically stringify your request data.

Change to:

$.ajax({
        type: "POST",
        url: hb_base_url + "consumer",
        contentType: "application/json",
        dataType: "json",
        data: JSON.stringify({
            first_name: $("#namec").val(),
            last_name: $("#surnamec").val(),
            email: $("#emailc").val(),
            mobile: $("#numberc").val(),
            password: $("#passwordc").val()
        }),
        success: function(response) {
            console.log(response);
        },
        error: function(response) {
            console.log(response);
        }
});

More fast way using directly a no-string array but a string:

string[] StringSplit(string StringToSplit, string Delimitator)
{
    return StringToSplit.Split(new[] { Delimitator }, StringSplitOptions.None);
}

StringSplit("E' una bella giornata oggi", "giornata");
/* Output
[0] "E' una bella giornata"
[1] " oggi"
*/

Here is the details from laravel.com

http://laravel.com/docs/eloquent#soft-deleting

When soft deleting a model, it is not actually removed from your database. Instead, a deleted_at timestamp is set on the record. To enable soft deletes for a model, specify the softDelete property on the model:

class User extends Eloquent {

    protected $softDelete = true;

}

To add a deleted_at column to your table, you may use the softDeletes method from a migration:

$table->softDeletes();

Now, when you call the delete method on the model, the deleted_at column will be set to the current timestamp. When querying a model that uses soft deletes, the "deleted" models will not be included in query results.

You can render a template in your code like so:

from django.template import Context, Template
t = Template('This is your <span>{{ message }}</span>.')

c = Context({'message': 'Your message'})
html = t.render(c)

See the Django docs for further information.

On Ubuntu:

sudo apt-get install python-virtualenv

The package python-pip is a dependency, so it will be installed as well.

CSS 3

divContainer input[type="text"] {
    width:150px;
}

CSS2 add a class "text" to the text inputs then in your css

.divContainer.text{
    width:150px;
}

Simply make coffee depend on clean, and develop depend on coffee:

gulp.task('coffee', ['clean'], function(){...});
gulp.task('develop', ['coffee'], function(){...});

Dispatch is now serial: clean → coffee → develop. Note that clean's implementation and coffee's implementation must accept a callback, "so the engine knows when it'll be done":

gulp.task('clean', function(callback){
  del(['dist/*'], callback);
});

In conclusion, below is a simple gulp pattern for a synchronous clean followed by asynchronous build dependencies:

//build sub-tasks
gulp.task('bar', ['clean'], function(){...});
gulp.task('foo', ['clean'], function(){...});
gulp.task('baz', ['clean'], function(){...});
...

//main build task
gulp.task('build', ['foo', 'baz', 'bar', ...], function(){...})

Gulp is smart enough to run clean exactly once per build, no matter how many of build's dependencies depend on clean. As written above, clean is a synchronization barrier, then all of build's dependencies run in parallel, then build runs.

You can use rename utility to rename multiple files by a pattern. For example following command will prepend string MyVacation2011_ to all the files with jpg extension.

rename 's/^/MyVacation2011_/g' *.jpg

or

rename <pattern> <replacement> <file-list>

You should be able to do this quite easily:

SELECT * 
FROM WebPageContent 
WHERE data.value('(/PageContent/Text)[1]', 'varchar(100)') LIKE 'XYZ%'

The .value method gives you the actual value, and you can define that to be returned as a VARCHAR(), which you can then check with a LIKE statement.

Mind you, this isn't going to be awfully fast. So if you have certain fields in your XML that you need to inspect a lot, you could:

• create a stored function which gets the XML and returns the value you're looking for as a VARCHAR()
• define a new computed field on your table which calls this function, and make it a PERSISTED column

With this, you'd basically "extract" a certain portion of the XML into a computed field, make it persisted, and then you can search very efficiently on it (heck: you can even INDEX that field!).

The .encode method gets applied to a Unicode string to make a byte-string; but you're calling it on a byte-string instead... the wrong way 'round! Look at the codecs module in the standard library and codecs.open in particular for better general solutions for reading UTF-8 encoded text files. However, for the csv module in particular, you need to pass in utf-8 data, and that's what you're already getting, so your code can be much simpler:

import csv

def unicode_csv_reader(utf8_data, dialect=csv.excel, **kwargs):
    csv_reader = csv.reader(utf8_data, dialect=dialect, **kwargs)
    for row in csv_reader:
        yield [unicode(cell, 'utf-8') for cell in row]

filename = 'da.csv'
reader = unicode_csv_reader(open(filename))
for field1, field2, field3 in reader:
  print field1, field2, field3 

PS: if it turns out that your input data is NOT in utf-8, but e.g. in ISO-8859-1, then you do need a "transcoding" (if you're keen on using utf-8 at the csv module level), of the form line.decode('whateverweirdcodec').encode('utf-8') -- but probably you can just use the name of your existing encoding in the yield line in my code above, instead of 'utf-8', as csv is actually going to be just fine with ISO-8859-* encoded bytestrings.

To solve your error I propose this solution: to work on Visual studio code editor and install live server extension in the editor, which allows you to connect to your local server, for me I put the picture in my workspace 127.0.0.1:5500/workspace/data/pict.png and it works!

"12345".each_char.map(&:to_i)

each_char does basically the same as split(''): It splits a string into an array of its characters.

hmmm, I just realize now that in the original question the string contains commas, so my answer is not really helpful ;-(..

Not sure why an answer with Linux commands would get so many up votes for a Windows related question, but anyway...

If phpinfo() shows Curl as enabled, yet php -m does NOT, it means that you probably have a php-cli.ini too. run php -i and see which ini file loaded. If it's different, diff it and reflect and differences in the CLI ini file. Then you should be good to go.

Btw download and use Git Bash instead of cmd.exe!

To do this using numpy, ie, if you have an array, a, instead of list_a:

a = np.array([1, 2, 4, 6])
my_filter = np.array([True, False, True, False], dtype=bool)
a[my_filter]
> array([1, 4])

In case of Select2 Version 4+

it has changed syntax and you need to write like this:

// clear all option
$('#select_with_blank_data').html('').select2({data: [{id: '', text: ''}]});

// clear and add new option
$("#select_with_data").html('').select2({data: [
 {id: '', text: ''},
 {id: '1', text: 'Facebook'},
 {id: '2', text: 'Youtube'},
 {id: '3', text: 'Instagram'},
 {id: '4', text: 'Pinterest'}]});

var inputs = document.querySelectorAll("input[type=text]") ||
(function() {
    var ret=[], elems = document.getElementsByTagName('input'), i=0,l=elems.length;
    for (;i<l;i++) {
        if (elems[i].type.toLowerCase() === "text") {
            ret.push(elems[i]);
        }
    }

    return ret;
}());

(Assuming C, C++, Java, JavaScript)

| and & are bitwise operators while || and && are logical operators. Usually you'd want to use || and && for if statements and loops and such (i.e. for your examples above). The bitwise operators are for setting and checking bits within bitmasks.

try to add display: block; (or replace the <span> by a <div>) (note that this could cause other problems becuase a <span> is inline by default - but you havn't posted the rest of your html)

You can have multiple tags when building the image:

$ docker build -t whenry/fedora-jboss:latest -t whenry/fedora-jboss:v2.1 .

Reference: https://docs.docker.com/engine/reference/commandline/build/#tag-image-t

Yes it can be eliminated with the /Yc options like others have pointed out but most likely you wouldn't need to touch it to fix it. Why are you getting this error in the first place without changing any settings? You might have 'cleaned' the project and than try to compile a single cpp file. You would get this error in that case because the precompiler header is now missing. Just build the whole project (even if unsuccessful) and than build any single cpp file and you won't get this error.

First approach with Windows Service is not easy..

A long time ago, I wrote a C# service.

This is the logic of the Service class (tested, works fine):

namespace MyServiceApp
{
    public class MyService : ServiceBase
    {
        private System.Timers.Timer timer;

        protected override void OnStart(string[] args)
        {
            this.timer = new System.Timers.Timer(30000D);  // 30000 milliseconds = 30 seconds
            this.timer.AutoReset = true;
            this.timer.Elapsed += new System.Timers.ElapsedEventHandler(this.timer_Elapsed);
            this.timer.Start();
        }

        protected override void OnStop()
        {
            this.timer.Stop();
            this.timer = null;
        }

        private void timer_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
        {
            MyServiceApp.ServiceWork.Main(); // my separate static method for do work
        }

        public MyService()
        {
            this.ServiceName = "MyService";
        }

        // service entry point
        static void Main()
        {
            System.ServiceProcess.ServiceBase.Run(new MyService());
        }
    }
}

I recommend you write your real service work in a separate static method (why not, in a console application...just add reference to it), to simplify debugging and clean service code.

Make sure the interval is enough, and write in log ONLY in OnStart and OnStop overrides.

Hope this helps!

You need to put the last() indexing on the nodelist result, rather than as part of the selection criteria. Try:

(//element[@name='D'])[last()]

public void setItem(List<Item> dataEntity, Item item) {
    int itemIndex = dataEntity.indexOf(item);
    if (itemIndex != -1) {
        dataEntity.set(itemIndex, item);
    }
}

answer = “True”

myvars = “the answer is” + answer

print(myvars)

That should give you the answer is True easily as you have stored answer as a string by using the quotation marks

Last or next date, week, month & year calculation. It might be helpful for anyone.

Since it's not possible to post code blocks into comments here's the POM template I am using in projects requiring JUnit 5. This allows to build and "Run as JUnit Test" in Eclipse and building the project with plain Maven.

You can see that now you only have to update the version in one place if you want to update JUnit. Also the platform version number does not need to appear (in a compatible version) anywhere in your POM, it's automatically managed via the junit-bom import.

Use this code to return and reload the current window:

function printpost() {
  if (window.print()) {
    return false;
  } else {
    location.reload();
  }
}

Avoid any? for large arrays.

• any? is O(n)
• empty? is O(1)

any? does not check the length but actually scans the whole array for truthy elements.

static VALUE
rb_ary_any_p(VALUE ary)
{
  long i, len = RARRAY_LEN(ary);
  const VALUE *ptr = RARRAY_CONST_PTR(ary);

  if (!len) return Qfalse;
  if (!rb_block_given_p()) {
    for (i = 0; i < len; ++i) if (RTEST(ptr[i])) return Qtrue;
  }
  else {
    for (i = 0; i < RARRAY_LEN(ary); ++i) {
        if (RTEST(rb_yield(RARRAY_AREF(ary, i)))) return Qtrue;
    }
  }
  return Qfalse;
}

empty? on the other hand checks the length of the array only.

static VALUE
rb_ary_empty_p(VALUE ary)
{
  if (RARRAY_LEN(ary) == 0)
    return Qtrue;
  return Qfalse;
}

The difference is relevant if you have "sparse" arrays that start with lots of nil values, like for example an array that was just created.

Use

public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
    return shouldOverrideUrlLoading(view, request.getUrl().toString());
}

I was trying to use aws-vault which uses pass and gnugp2 (gpg2). I'm on Ubuntu 20.04 running in WSL2.

I tried all the solutions above, and eventually, I had to do one more thing -

$ rm ~/.gnupg/S.*                    # remove cache
$ gpg-connect-agent reloadagent /bye # restart gpg agent
$ export GPG_TTY=$(tty)              # prompt for password
# ^ This last line should be added to your ~/.bashrc file

The source of this solution is from some blog-post in Japanese, luckily there's Google Translate :)

You could do that in a single statement

cat("hello","world",file="output.txt",sep="\n",append=TRUE)

I suggest using the Google Charts API because you can specify the text, text color, fill color and outline color, all using hex color codes, e.g. #FF0000 for red. You can call it as follows:

function getIcon(text, fillColor, textColor, outlineColor) {
  if (!text) text = '•'; //generic map dot
  var iconUrl = "http://chart.googleapis.com/chart?cht=d&chdp=mapsapi&chl=pin%27i\\%27[" + text + "%27-2%27f\\hv%27a\\]h\\]o\\" + fillColor + "%27fC\\" + textColor + "%27tC\\" + outlineColor + "%27eC\\Lauto%27f\\&ext=.png";
  return iconUrl;
}

Then, when you create your marker you just set the icon property as such, where the myColor variables are hex values (minus the hash sign):

var marker = new google.maps.Marker({
  position: new google.maps.LatLng(locations[i][1], locations[i][2]),
  animation: google.maps.Animation.DROP,
  map: map,
  icon: getIcon(null, myColor, myColor2, myColor3)
});

You can use http://chart.googleapis.com/chart?chst=d_map_pin_letter&chld=•|FF0000, which is a bit easier to decipher, as an alternate URL if you only need to set text and fill color.

khurram's answer refers to a 3rd party site that redirects to the Google Charts API. This means if that person takes down their server you're hosed. I prefer having the flexibility the Google API offers as well as the reliability of going directly to Google. Just make sure you specify a value for each of the colors or it won't work.

You can't avoid a server call here, JavaScript simply cannot (for security reasons) save a file to the user's file system. You'll have to submit your data to the server and have it send the .csv as a link or an attachment directly.

HTML5 has some ability to do this (though saving really isn't specified - just a use case, you can read the file if you want), but there's no cross-browser solution in place now.

Because the answer is no longer valid with a more stable version of angular, I am posting a newer solution.

PHP Page: session.php

if (!isset($_SESSION))
{    
    session_start();
}    

$_SESSION['variable'] = "hello world";

$sessions = array();

$sessions['variable'] = $_SESSION['variable'];

header('Content-Type: application/json');
echo json_encode($sessions);

Send back only the session variables you want in Angular not all of them don't want to expose more than what is needed.

JS All Together

var app = angular.module('StarterApp', []);
app.controller("AppCtrl", ['$rootScope', 'Session', function($rootScope, Session) {      
    Session.then(function(response){
        $rootScope.session = response;
    });
}]);

 app.factory('Session', function($http) {    
    return $http.get('/session.php').then(function(result) {       
        return result.data; 
    });
}); 

• Do a simple get to get sessions using a factory.
• If you want to make it post to make the page not visible when you just go to it in the browser you can, I'm just simplifying it
• Add the factory to the controller
• I use rootScope because it is a session variable that I use throughout all my code.

HTML

Inside your html you can reference your session

<html ng-app="StarterApp">

<body ng-controller="AppCtrl">
{{ session.variable }}
</body>

If they are .NET created services you can use the installutil.exe with the /u switch its in the .net framework folder like C:\Windows\Microsoft.NET\Framework64\v2.0.50727

Note that starting git1.8.4 (July 2013), you wouldn't have to go back to the root directory anymore.

 cd ~/.janus/snipmate-snippets
 git submodule add <git@github ...> snippets

(Bouke Versteegh comments that you don't have to use /., as in snippets/.: snippets is enough)

See commit 091a6eb0feed820a43663ca63dc2bc0bb247bbae:

submodule: drop the top-level requirement

Use the new rev-parse --prefix option to process all paths given to the submodule command, dropping the requirement that it be run from the top-level of the repository.

Since the interpretation of a relative submodule URL depends on whether or not "remote.origin.url" is configured, explicitly block relative URLs in "git submodule add" when not at the top level of the working tree.

Signed-off-by: John Keeping

Depends on commit 12b9d32790b40bf3ea49134095619700191abf1f

This makes 'git rev-parse' behave as if it were invoked from the specified subdirectory of a repository, with the difference that any file paths which it prints are prefixed with the full path from the top of the working tree.

This is useful for shell scripts where we may want to cd to the top of the working tree but need to handle relative paths given by the user on the command line.

Fiddle this

When you put the username and password in front of the host, this data is not sent that way to the server. It is instead transformed to a request header depending on the authentication schema used. Most of the time this is going to be Basic Auth which I describe below. A similar (but significantly less often used) authentication scheme is Digest Auth which nowadays provides comparable security features.

With Basic Auth, the HTTP request from the question will look something like this:

GET / HTTP/1.1
Host: example.com
Authorization: Basic Zm9vOnBhc3N3b3Jk

The hash like string you see there is created by the browser like this: base64_encode(username + ":" + password).

To outsiders of the HTTPS transfer, this information is hidden (as everything else on the HTTP level). You should take care of logging on the client and all intermediate servers though. The username will normally be shown in server logs, but the password won't. This is not guaranteed though. When you call that URL on the client with e.g. curl, the username and password will be clearly visible on the process list and might turn up in the bash history file.

When you send passwords in a GET request as e.g. http://example.com/login.php?username=me&password=secure the username and password will always turn up in server logs of your webserver, application server, caches, ... unless you specifically configure your servers to not log it. This only applies to servers being able to read the unencrypted http data, like your application server or any middleboxes such as loadbalancers, CDNs, proxies, etc. though.

Basic auth is standardized and implemented by browsers by showing this little username/password popup you might have seen already. When you put the username/password into an HTML form sent via GET or POST, you have to implement all the login/logout logic yourself (which might be an advantage and allows you to more control over the login/logout flow for the added "cost" of having to implement this securely again). But you should never transfer usernames and passwords by GET parameters. If you have to, use POST instead. The prevents the logging of this data by default.

When implementing an authentication mechanism with a user/password entry form and a subsequent cookie-based session as it is commonly used today, you have to make sure that the password is either transported with POST requests or one of the standardized authentication schemes above only.

Concluding I could say, that transfering data that way over HTTPS is likely safe, as long as you take care that the password does not turn up in unexpected places. But that advice applies to every transfer of any password in any way.

Some notes to complement the ALTER DATABASE process:

1) You can obtain a full list of databases with logical names and full paths of MDF and LDF files:

   USE master SELECT name, physical_name FROM sys.master_files

2) You can move manually the files with CMD move command:

Move "Source" "Destination"

Example:

md "D:\MSSQLData"
Move "C:\test\SYSADMIT-DB.mdf" "D:\MSSQLData\SYSADMIT-DB_Data.mdf"
Move "C:\test\SYSADMIT-DB_log.ldf" "D:\MSSQLData\SYSADMIT-DB_log.ldf"

3) You should change the default database path for new databases creation. The default path is obtained from the Windows registry.

You can also change with T-SQL, for example, to set default destination to: D:\MSSQLData

USE [master]

GO

EXEC xp_instance_regwrite N'HKEY_LOCAL_MACHINE', N'Software\Microsoft\MSSQLServer\MSSQLServer', N'DefaultData', REG_SZ, N'D:\MSSQLData'

GO

EXEC xp_instance_regwrite N'HKEY_LOCAL_MACHINE', N'Software\Microsoft\MSSQLServer\MSSQLServer', N'DefaultLog', REG_SZ, N'D:\MSSQLData'

One way to order by positive integers, when they are stored as varchar, is to order by the length first and then the value:

order by len(registration_no), registration_no

This is particularly useful when the column might contain non-numeric values.

Note: in some databases, the function to get the length of a string might be called length() instead of len().

RFC 2396 section 4.1:

When a URI reference is used to perform a retrieval action on the identified resource, the optional fragment identifier, separated from the URI by a crosshatch ("#") character, consists of additional reference information to be interpreted by the user agent after the retrieval action has been successfully completed. As such, it is not part of a URI, but is often used in conjunction with a URI.

(emphasis added)

Cast the operands to floats:

float ans = (float)a / (float)b;

This is what I do to reload the activity after changing returning from a preference change.

@Override
protected void onResume() {

   super.onResume();
   this.onCreate(null);
}

This essentially causes the activity to redraw itself.

Updated: A better way to do this is to call the recreate() method. This will cause the activity to be recreated.

Open a Windows PowerShell window and type:

notepad $profile

Then create a function, such as:

function goSomewhereThenOpenGoogleThenDeleteSomething {
    cd C:\Users\
    Start-Process -FilePath "http://www.google.com"
    rm fileName.txt
}

Then type this under the function name:

Set-Alias google goSomewhereThenOpenGoogleThenDeleteSomething

Now you can type the word "google" into Windows PowerShell and have it execute the code within your function!

The problem is that you are asking for an object of type ChannelSearchEnum but what you actually have is an object of type List<ChannelSearchEnum>.

You can achieve this with:

Type collectionType = new TypeToken<List<ChannelSearchEnum>>(){}.getType();
List<ChannelSearchEnum> lcs = (List<ChannelSearchEnum>) new Gson()
               .fromJson( jstring , collectionType);

Update: ICS emulator supports camera.

Well, actually, React is not suitable for calling child methods from the parent. Some frameworks, like Cycle.js, allow easily access data both from parent and child, and react to it.

Also, there is a good chance you don't really need it. Consider calling it into existing component, it is much more independent solution. But sometimes you still need it, and then you have few choices:

• Pass method down, if it is a child (the easiest one, and it is one of the passed properties)
• add events library; in React ecosystem Flux approach is the most known, with Redux library. You separate all events into separated state and actions, and dispatch them from components
• if you need to use function from the child in a parent component, you can wrap in a third component, and clone parent with augmented props.

UPD: if you need to share some functionality which doesn't involve any state (like static functions in OOP), then there is no need to contain it inside components. Just declare it separately and invoke when need:

let counter = 0;
function handleInstantiate() {
   counter++;
}

constructor(props) {
   super(props);
   handleInstantiate();
}

Replace:

myBinding.Source = ViewModel.SomeString;

with:

myBinding.Source = ViewModel;

Example:

Binding myBinding = new Binding();
myBinding.Source = ViewModel;
myBinding.Path = new PropertyPath("SomeString");
myBinding.Mode = BindingMode.TwoWay;
myBinding.UpdateSourceTrigger = UpdateSourceTrigger.PropertyChanged;
BindingOperations.SetBinding(txtText, TextBox.TextProperty, myBinding);

Your source should be just ViewModel, the .SomeString part is evaluated from the Path (the Path can be set by the constructor or by the Path property).

Here is how I implemented it.

import urllib

params = urllib.urlencode({'lang':'en','tag':'python'})
url = ''
if request.GET:
   url = request.url + '&' + params
else:
   url = request.url + '?' + params    

Worked like a charm. However, I would have liked a more cleaner way to implement this.

Another way of implementing the above is put it in a method.

import urllib

def add_url_param(request, **params):
   new_url = ''
   _params = dict(**params)
   _params = urllib.urlencode(_params)

   if _params:
      if request.GET:
         new_url = request.url + '&' + _params
      else:
         new_url = request.url + '?' + _params
   else:
      new_url = request.url

   return new_ur

The Google Closure library has functions to convert to/from UTF-8 and byte arrays. If you don't want to use the whole library, you can copy the functions from here. For completeness, the code to convert to a string to a UTF-8 byte array is:

goog.crypt.stringToUtf8ByteArray = function(str) {
  // TODO(user): Use native implementations if/when available
  var out = [], p = 0;
  for (var i = 0; i < str.length; i++) {
    var c = str.charCodeAt(i);
    if (c < 128) {
      out[p++] = c;
    } else if (c < 2048) {
      out[p++] = (c >> 6) | 192;
      out[p++] = (c & 63) | 128;

There are a couple of ways:

To delete it directly:

SomeModel.objects.filter(id=id).delete()

To delete it from an instance:

instance1 = SomeModel.objects.get(id=id)
instance1.delete()

You appear to have a heredoc containing a single SQL*Plus command, though it doesn't look right as noted in the comments. You can either pass a value in the heredoc:

sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql BUILDING
exit;
EOF

or if BUILDING is $2 in your script:

sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql $2
exit;
EOF

If your file.sql had an exit at the end then it would be even simpler as you wouldn't need the heredoc:

sqlplus -S user/pass@localhost @/opt/D2RQ/file.sql $2

In your SQL you can then refer to the position parameters using substitution variables:

...
}',SEM_Models('&1'),NULL,
...

The &1 will be replaced with the first value passed to the SQL script, BUILDING; because that is a string it still needs to be enclosed in quotes. You might want to set verify off to stop if showing you the substitutions in the output.

You can pass multiple values, and refer to them sequentially just as you would positional parameters in a shell script - the first passed parameter is &1, the second is &2, etc. You can use substitution variables anywhere in the SQL script, so they can be used as column aliases with no problem - you just have to be careful adding an extra parameter that you either add it to the end of the list (which makes the numbering out of order in the script, potentially) or adjust everything to match:

sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql total_count BUILDING
exit;
EOF

or:

sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql total_count $2
exit;
EOF

If total_count is being passed to your shell script then just use its positional parameter, $4 or whatever. And your SQL would then be:

SELECT COUNT(*) as &1
FROM TABLE(SEM_MATCH(
'{
        ?s rdf:type :ProcessSpec .
        ?s ?p ?o
}',SEM_Models('&2'),NULL,
SEM_ALIASES(SEM_ALIAS('','http://VISION/DataSource/SEMANTIC_CACHE#')),NULL));

If you pass a lot of values you may find it clearer to use the positional parameters to define named parameters, so any ordering issues are all dealt with at the start of the script, where they are easier to maintain:

define MY_ALIAS = &1
define MY_MODEL = &2

SELECT COUNT(*) as &MY_ALIAS
FROM TABLE(SEM_MATCH(
'{
        ?s rdf:type :ProcessSpec .
        ?s ?p ?o
}',SEM_Models('&MY_MODEL'),NULL,
SEM_ALIASES(SEM_ALIAS('','http://VISION/DataSource/SEMANTIC_CACHE#')),NULL));

From your separate question, maybe you just wanted:

SELECT COUNT(*) as &1
FROM TABLE(SEM_MATCH(
'{
        ?s rdf:type :ProcessSpec .
        ?s ?p ?o
}',SEM_Models('&1'),NULL,
SEM_ALIASES(SEM_ALIAS('','http://VISION/DataSource/SEMANTIC_CACHE#')),NULL));

... so the alias will be the same value you're querying on (the value in $2, or BUILDING in the original part of the answer). You can refer to a substitution variable as many times as you want.

That might not be easy to use if you're running it multiple times, as it will appear as a header above the count value in each bit of output. Maybe this would be more parsable later:

select '&1' as QUERIED_VALUE, COUNT(*) as TOTAL_COUNT

If you set pages 0 and set heading off, your repeated calls might appear in a neat list. You might also need to set tab off and possibly use rpad('&1', 20) or similar to make that column always the same width. Or get the results as CSV with:

select '&1' ||','|| COUNT(*)

Depends what you're using the results for...

Simple just log into your GitHub account and on the far right side in the navigation menu choose Settings, in the Settings Tab choose Default Branch and return back to main page of your repository that did the trick for me.

The Gutenberg Project hosts Webster's Unabridged English Dictionary plus many other public domain literary works. Actually it looks like they've got several versions of the dictionary hosted with copyright from different years. The one I linked has a 2009 copyright. You may want to poke around the site and investigate the different versions of Webster's dictionary.

I wrote a small class to test which has the better performance of the two and + comes ahead of format. by a factor of 5 to 6. Try it your self

import java.io.*;
import java.util.Date;

public class StringTest{

    public static void main( String[] args ){
    int i = 0;
    long prev_time = System.currentTimeMillis();
    long time;

    for( i = 0; i< 100000; i++){
        String s = "Blah" + i + "Blah";
    }
    time = System.currentTimeMillis() - prev_time;

    System.out.println("Time after for loop " + time);

    prev_time = System.currentTimeMillis();
    for( i = 0; i<100000; i++){
        String s = String.format("Blah %d Blah", i);
    }
    time = System.currentTimeMillis() - prev_time;
    System.out.println("Time after for loop " + time);

    }
}

Running the above for different N shows that both behave linearly, but String.format is 5-30 times slower.

The reason is that in the current implementation String.format first parses the input with regular expressions and then fills in the parameters. Concatenation with plus, on the other hand, gets optimized by javac (not by the JIT) and uses StringBuilder.append directly.

Just an observation about the markup The markup form in prior versions of HTML provided an anchor point. The markup forms in HTML5 using the id attribute, while mostly equivalent, require an element to identify, almost all of which are normally expected to contain content.

An empty span or div could be used, for instance, but this usage looks and smells degenerate.

One thought is to use the wbr element for this purpose. The wbr has an empty content model and simply declares that a line break is possible; this is still a slightly gratuitous use of a markup tag, but much less so than gratuitous document divisions or empty text spans.

$Date3 = date('y-m-d');
$Date2 = date('y-m-d', strtotime("-7 days"));

SELECT * FROM disaster WHERE date BETWEEN '".$Date2."' AND  '".$Date3."'

<form action="javascript:completeAndRedirect();">
    <input type="text" id="Edit1" 
    style="width:280; height:50; font-family:'Lucida Sans Unicode', 'Lucida Grande', sans-serif; font-size:22px">
</form>

Changing action to point at your function would solve the problem, in a different way.

Let's measure the performance by using the following piece of code.

import numpy as np
import time

exec_time0 = []
exec_time1 = []
exec_time2 = []

sizeOfArray = 5000
numOfIterations = 200

for i in xrange(numOfIterations):

    A = np.random.randint(0,255,(sizeOfArray,sizeOfArray))
    B = np.random.randint(0,255,(sizeOfArray,sizeOfArray))

    a = time.clock() 
    res = (A==B).all()
    b = time.clock()
    exec_time0.append( b - a )

    a = time.clock() 
    res = np.array_equal(A,B)
    b = time.clock()
    exec_time1.append( b - a )

    a = time.clock() 
    res = np.array_equiv(A,B)
    b = time.clock()
    exec_time2.append( b - a )

print 'Method: (A==B).all(),       ', np.mean(exec_time0)
print 'Method: np.array_equal(A,B),', np.mean(exec_time1)
print 'Method: np.array_equiv(A,B),', np.mean(exec_time2)

Output

Method: (A==B).all(),        0.03031857
Method: np.array_equal(A,B), 0.030025185
Method: np.array_equiv(A,B), 0.030141515

According to the results above, the numpy methods seem to be faster than the combination of the == operator and the all() method and by comparing the numpy methods the fastest one seems to be the numpy.array_equal method.

You can use dynamic variable names and let the variables names work like the keys of a hashmap.

For example, if you have an input file with two columns, name, credit, as the example bellow, and you want to sum the income of each user:

Mary 100
John 200
Mary 50
John 300
Paul 100
Paul 400
David 100

The command bellow will sum everything, using dynamic variables as keys, in the form of map_${person}:

while read -r person money; ((map_$person+=$money)); done < <(cat INCOME_REPORT.log)

To read the results:

set | grep map

The output will be:

map_David=100
map_John=500
map_Mary=150
map_Paul=500

Elaborating on these techniques, I'm developing on GitHub a function that works just like a HashMap Object, shell_map.

In order to create "HashMap instances" the shell_map function is able create copies of itself under different names. Each new function copy will have a different $FUNCNAME variable. $FUNCNAME then is used to create a namespace for each Map instance.

The map keys are global variables, in the form $FUNCNAME_DATA_$KEY, where $KEY is the key added to the Map. These variables are dynamic variables.

Bellow I'll put a simplified version of it so you can use as example.

#!/bin/bash

shell_map () {
    local METHOD="$1"

    case $METHOD in
    new)
        local NEW_MAP="$2"

        # loads shell_map function declaration
        test -n "$(declare -f shell_map)" || return

        # declares in the Global Scope a copy of shell_map, under a new name.
        eval "${_/shell_map/$2}"
    ;;
    put)
        local KEY="$2"  
        local VALUE="$3"

        # declares a variable in the global scope
        eval ${FUNCNAME}_DATA_${KEY}='$VALUE'
    ;;
    get)
        local KEY="$2"
        local VALUE="${FUNCNAME}_DATA_${KEY}"
        echo "${!VALUE}"
    ;;
    keys)
        declare | grep -Po "(?<=${FUNCNAME}_DATA_)\w+((?=\=))"
    ;;
    name)
        echo $FUNCNAME
    ;;
    contains_key)
        local KEY="$2"
        compgen -v ${FUNCNAME}_DATA_${KEY} > /dev/null && return 0 || return 1
    ;;
    clear_all)
        while read var; do  
            unset $var
        done < <(compgen -v ${FUNCNAME}_DATA_)
    ;;
    remove)
        local KEY="$2"
        unset ${FUNCNAME}_DATA_${KEY}
    ;;
    size)
        compgen -v ${FUNCNAME}_DATA_${KEY} | wc -l
    ;;
    *)
        echo "unsupported operation '$1'."
        return 1
    ;;
    esac
}

Usage:

shell_map new credit
credit put Mary 100
credit put John 200
for customer in `credit keys`; do 
    value=`credit get $customer`       
    echo "customer $customer has $value"
done
credit contains_key "Mary" && echo "Mary has credit!"

High-Level Design (HLD) involves decomposing a system into modules, and representing the interfaces & invocation relationships among modules. An HLD is referred to as software architecture.

LLD, also known as a detailed design, is used to design internals of the individual modules identified during HLD i.e. data structures and algorithms of the modules are designed and documented.

Now, HLD and LLD are actually used in traditional Approach (Function-Oriented Software Design) whereas, in OOAD, the system is seen as a set of objects interacting with each other.

As per the above definitions, a high-level design document will usually include a high-level architecture diagram depicting the components, interfaces, and networks that need to be further specified or developed. The document may also depict or otherwise refer to work flows and/or data flows between component systems.

Class diagrams with all the methods and relations between classes come under LLD. Program specs are covered under LLD. LLD describes each and every module in an elaborate manner so that the programmer can directly code the program based on it. There will be at least 1 document for each module. The LLD will contain - a detailed functional logic of the module in pseudo code - database tables with all elements including their type and size - all interface details with complete API references(both requests and responses) - all dependency issues - error message listings - complete inputs and outputs for a module.

Have you given the permission in the manifest file

 <uses-permission android:name="android.permission.CALL_PHONE"></uses-permission>   

and inside your activity

  Intent callIntent = new Intent(Intent.ACTION_CALL);
    callIntent.setData(Uri.parse("tel:123456789"));
    startActivity(callIntent);

Let me know if you find any issue.

Why don't you try this (in the 2nd line where 'form#' you need to put the proper selector of your html form):

$('.checkAll').click(function(){
    $('form#myForm input:checkbox').each(function(){
        $(this).prop('checked',true);
   })               
});

$('.uncheckAll').click(function(){
    $('form#myForm input:checkbox').each(function(){
        $(this).prop('checked',false);
   })               
});

Your html should be like this:

<form id="myForm">
      <span class="checkAll">checkAll</span>
      <span class="uncheckAll">uncheckAll</span>
      <input type="checkbox" class="checkSingle"></input>
      ....
</form>

I hope that helps.

I had the same issue in cPanel 92.0.3 and it was solved through this solution:

In cPanel go to the below directory

software --> select PHP version--> option--> upload_max_filesize 

Then choose the optional size to upload your files.

TryParse is faster...

The first of these functions, Parse, is one that should be familiar to any .Net developer. This function will take a string and attempt to extract an integer out of it and then return the integer. If it runs into something that it can’t parse then it throws a FormatException or if the number is too large an OverflowException. Also, it can throw an ArgumentException if you pass it a null value.

TryParse is a new addition to the new .Net 2.0 framework that addresses some issues with the original Parse function. The main difference is that exception handling is very slow, so if TryParse is unable to parse the string it does not throw an exception like Parse does. Instead, it returns a Boolean indicating if it was able to successfully parse a number. So you have to pass into TryParse both the string to be parsed and an Int32 out parameter to fill in. We will use the profiler to examine the speed difference between TryParse and Parse in both cases where the string can be correctly parsed and in cases where the string cannot be correctly parsed.

The Convert class contains a series of functions to convert one base class into another. I believe that Convert.ToInt32(string) just checks for a null string (if the string is null it returns zero unlike the Parse) then just calls Int32.Parse(string). I’ll use the profiler to confirm this and to see if using Convert as opposed to Parse has any real effect on performance.

Source with examples

Hope this helps.

I hope the below mentioned code will answer your question.

def root(x,a):
    y = 1 / a
    y = float(y)
    print y
    z = x ** y
    print z

base = input("Please input the base value:")
power = float(input("Please input the root value:"))


root(base,power) 

Why would you use it if you already knew the class and were going to cast it? Why not just do it the old fashioned way and make the class like you always make it? There's no advantage to this over the way it's done normally. Is there a way to take the text and operate on it thusly:

label1.txt = "Pizza" 
Magic(label1.txt) p = new Magic(lablel1.txt)(arg1, arg2, arg3);
p.method1();
p.method2();

If I already know its a Pizza there's no advantage to:

p = (Pizza)somefancyjunk("Pizza"); over
Pizza p = new Pizza();

but I see a huge advantage to the Magic method if it exists.

As the others have said, you can use var at global scope (outside of all functions and modules) to declare a global variable:

<script>
var yourGlobalVariable;
function foo() {
    // ...
}
</script>

(Note that that's only true at global scope. If that code were in a module — <script type="module">...</script> — it wouldn't be at global scope, so that wouldn't create a global.)

Alternatively:

In modern environments, you can assign to a property on the object that globalThis refers to (globalThis was added in ES2020):

<script>
function foo() {
    globalThis.yourGlobalVariable = ...;
}
</script>

On browsers, you can do the same thing with the global called window:

<script>
function foo() {
    window.yourGlobalVariable = ...;
}
</script>

...because in browsers, all global variables global variables declared with var are properties of the window object. (In the latest specification, ECMAScript 2015, the new let, const, and class statements at global scope create globals that aren't properties of the global object; a new concept in ES2015.)

(There's also the horror of implicit globals, but don't do it on purpose and do your best to avoid doing it by accident, perhaps by using ES5's "use strict".)

All that said: I'd avoid global variables if you possibly can (and you almost certainly can). As I mentioned, they end up being properties of window, and window is already plenty crowded enough what with all elements with an id (and many with just a name) being dumped in it (and regardless that upcoming specification, IE dumps just about anything with a name on there).

Instead, in modern environments, use modules:

<script type="module">
let yourVariable = 42;
// ...
</script>

The top level code in a module is at module scope, not global scope, so that creates a variable that all of the code in that module can see, but that isn't global.

In obsolete environments without module support, wrap your code in a scoping function and use variables local to that scoping function, and make your other functions closures within it:

<script>
(function() { // Begin scoping function
    var yourGlobalVariable; // Global to your code, invisible outside the scoping function
    function foo() {
        // ...
    }
})();         // End scoping function
</script>

Depending on the AWK implementation are you using == is ok or not.

Have you tried ~?. For example, if you want $1 to be "hello":

awk '$1 ~ /^hello$/{ print $3; }' <infile>

^ means $1 start, and $ is $1 end.

I don't know the platform you're doing this on but I assume Windows due to the .bat extension.

Also I don't have a way to check this but this seems like the batch processor skips the If lines due to some errors and then executes the one with -dev.

You could try this by chaning the two jump targets (:yes and :no) along with the code. If then the line without -dev is executed you know your If lines are erroneous.

If so, please check if == is really the right way to do a comparison in .bat files.

Also, judging from the way bash does this stuff, %foo=="y" might evaluate to true only if %foo includes the quotes. So maybe "%foo"=="y" is the way to go.

"Allocation Failure" is cause of GC to kick is not correct. It is an outcome of GC operation.

GC kicks in when there is no space to allocate( depending on region minor or major GC is performed). Once GC is performed if space is freed good enough, but if there is not enough size it fails. Allocation Failure is one such failure. Below document have good explanation https://docs.oracle.com/javase/8/docs/technotes/guides/vm/gctuning/g1_gc.html

Without converting to a string you could try:

Math.Ceiling(Math.Log10(n));

Correction following ysap's comment:

Math.Floor(Math.Log10(n) + 1);

function initialize() {
    var location = new google.maps.LatLng(44.5403, -78.5463);
    var mapCanvas = document.getElementById('map_canvas');
    var map_options = {
      center: location,
      zoom: 15,
      mapTypeId: google.maps.MapTypeId.ROADMAP
    }
    var map = new google.maps.Map(map_canvas, map_options);

    new google.maps.Marker({
        position: location,
        map: map
    });
}
google.maps.event.addDomListener(window, 'load', initialize);

Even after 9 years of the original post, this helped me.

If you are receiving these types of errors without any clue, there should be a trigger, function related to the table, and obviously it should end up with an SP, or function with selecting/filtering data NOT USING Primary Unique column. If you are searching/filtering using the Primary Unique column there won't be any multiple results. Especially when you are assigning value for a declared variable. The SP never gives you en error but only an runtime error.

 "System.Data.SqlClient.SqlException (0x80131904): Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.
    The statement has been terminated."

In my case obviously there was no clue, but only this error message. There was a trigger connected to the table and the table updating by the trigger also had another trigger likewise it ended up with two triggers and in the end with an SP. The SP was having a select clause which was resulting in multiple rows.

SET @Variable1 =(
        SELECT column_gonna_asign
        FROM dbo.your_db
        WHERE Non_primary_non_unique_key= @Variable2

If this returns multiple rows, you are in trouble.

Use the below function and use days paramater to get the date daysAhead/daysBehind just pass parameter as positive for future date or negative for previous dates:

+ (NSDate *) getDate:(NSDate *)fromDate daysAhead:(NSUInteger)days
{
    NSDateComponents *dateComponents = [[NSDateComponents alloc] init];
    dateComponents.day = days;
    NSCalendar *calendar = [NSCalendar currentCalendar];
    NSDate *previousDate = [calendar dateByAddingComponents:dateComponents
                                                     toDate:fromDate
                                                    options:0];
    [dateComponents release];
    return previousDate;
}

In general, these answer the question: How to change your user settings file? But the question I wanted answered was how to change my local maven repository location. The answer is that you have to edit settings.xml. If the file does not exist, you have to create it. You set or change the location of the file at Window > Preferences > Maven > User Settings. It's the User Settings entry at

It's the second file input; the first with information in it.

If it's not clear, [redacted] should be replaced with the local file path to your .m2 folder.

If you click the "open file" link, it opens the settings.xml file for editing in Eclipse.

If you have no settings.xml file yet, the following will set the local repository to the Windows 10 default value for a user named mdfst13:

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0
                              https://maven.apache.org/xsd/settings-1.0.0.xsd">

  <localRepository>C:\Users\mdfst13\.m2\repository</localRepository>
</settings>

You should set this to a value appropriate to your system. I haven't tested it, but I suspect that in Linux, the default value would be /home/mdfst13/.m2/repository. And of course, you probably don't want to set it to the default value. If you are reading this, you probably want to set it to some other value. You could just delete it if you wanted the default.

Credit to this comment by @ejaenv for the name of the element in the settings file: <localRepository>. See Maven — Settings Reference for more information.

Credit to @Ajinkya's answer for specifying the location of the User Settings value in Eclipse Photon.

If you already have a settings.xml file, you should merge this into your existing file. I.e. <settings and <localRepository> should only appear once in the file, and you probably want to retain any settings already there. Or to say that another way, edit any existing local repository entry if it exists or just add that line to the file if it doesn't.

I had to restart Eclipse for it to load data into the new repository. Neither "Update Settings" nor "Reindex" was sufficient.

An elegant RxJava/Kotlin solution is to use Completable.fromCallable, which will give you an Observable which does not return a value, but can observed and subscribed on a different thread.

public Completable insert(Event event) {
    return Completable.fromCallable(new Callable<Void>() {
        @Override
        public Void call() throws Exception {
            return database.eventDao().insert(event)
        }
    }
}

Or in Kotlin:

fun insert(event: Event) : Completable = Completable.fromCallable {
    database.eventDao().insert(event)
}

You can the observe and subscribe as you would usually:

dataManager.insert(event)
    .subscribeOn(scheduler)
    .observeOn(AndroidSchedulers.mainThread())
    .subscribe(...)

If the object element you get is a function, you can try this:

var url = myArray[i]();

function_that_needs_strings(*my_list) # works!

You can read all about it here.

all answers are correct, but I want to mention that time delta accepts negative arguments.

To answer your question - nginx picks the first server if there's no match. See documentation:

If its value does not match any server name, or the request does not contain this header field at all, then nginx will route the request to the default server for this port. In the configuration above, the default server is the first one...

Now, if you wanted to have a default catch-all server that, say, responds with 404 to all requests, then here's how to do it:

server {
    listen 80 default_server;
    listen 443 ssl default_server;
    server_name _;
    ssl_certificate <path to cert>
    ssl_certificate_key <path to key>
    return 404;
}

Note that you need to specify certificate/key (that can be self-signed), otherwise all SSL connections will fail as nginx will try to accept connection using this default_server and won't find cert/key.

This exception is also thrown when a non-existent property is being updated dynamically, using reflection.

If one is using reflection to dynamically update property values, it's worth checking to make sure the passed PropertyName is identical to the actual property.

In my case, I was attempting to update Employee.firstName, but the property was actually Employee.FirstName.

Worth keeping in mind. :)

it depends if your language and code promotes: LBYL (look before you leap) or EAFP (easier to ask forgiveness than permission)

LBYL says you should check for values (so return a null)
EAFP says to just try the operation and see if it fails (throw an exception)

though I agree with above.. exceptions should be used for exceptional/error conditions, and returning a null is best when using checks.

EAFP vs. LBYL in Python:

In case if someone is using Gradle for the build then fix will be by adding the following lines in build.gradle file

apply plugin: 'application'

mainClassName = "com.example.demo.DemoApplication"

Please also note that from iOS9 we can define constraints programmatically "more concise, and easier to read" using subclasses of the new helper class NSLayoutAnchor.

An example from the doc:

[self.cancelButton.leadingAnchor constraintEqualToAnchor:self.saveButton.trailingAnchor constant: 8.0].active = true;

perhaps

$id = isset($_GET['id'])?$_GET['id']:null;

and

$other_var = isset($_GET['othervar'])?$_GET['othervar']:null;

The best way I see is to use live() or delegate() to capture the event in a parent and not in each child element.

If your button is inside a #parent element, you can replace:

$('#myButton').bind('click', onButtonClicked);

by

$('#parent').delegate('#myButton', 'click', onButtonClicked);

even if #myButton doesn't exist yet when this code is executed.

And of course dependency injection, or IoC (inversion of control), which is central to the whole BeanFactory/ApplicationContext stuff.

You can just add , in the end of print function so it won't print on new line.

You can do this all within your controller by using the $window service here. $window is a wrapper around the global browser object window.

To make this work inject $window into you controller as follows

.controller('exampleCtrl', ['$scope', '$window',
    function($scope, $window) {
        $scope.redirectToGoogle = function(){
            $window.open('https://www.google.com', '_blank');
        };
    }
]);

this works well when redirecting to dynamic routes

Actually, you can write your StyleSheet.create object as a key with function value, it works properly but it has a type issue in TypeScript:

import React from 'react';
import { View, Text, StyleSheet } from 'react-native';

const SomeComponent = ({ bgColor }) => (
  <View style={styles.wrapper(bgColor)}>
    <Text style={styles.text}>3333</Text>
  </View>
);

const styles = StyleSheet.create({
  wrapper: color => ({
    flex: 1,
    backgroundColor: color,
  }),
  text: {
    color: 'red',
  },
});

After checking the permission of the folder, it is okay with 744. I had the problem with a plugin that is installed on my WordPress site. The plugin has hooked that are in the corn job I suspected.

With a simple sudo it can fix the issue

sudo git pull origin master

You have it working.

select 
CONCAT(CAST(CREATEDATE AS DATE),' ',datepart(hour,createdate),':',ROUNd(CAST((CAST((CAST(DATEPART(MINUTE,CREATEDATE) AS DECIMAL (18,4)))/5 AS INT)) AS DECIMAL (18,4))/12*60,2)) AS '5MINDATE'
,count(something)
from TABLE
group by CONCAT(CAST(CREATEDATE AS DATE),' ',datepart(hour,createdate),':',ROUNd(CAST((CAST((CAST(DATEPART(MINUTE,CREATEDATE) AS DECIMAL (18,4)))/5 AS INT)) AS DECIMAL (18,4))/12*60,2))

In case you have space in your path, wrap it in double quotes:

$ git clone "//serverName/New Folder/Target" f1/

The best way is surely just to check whether there are two program files directories, 'Program Files'and 'Program Files (x86)' The advantage of this method is you can do it when the o/s is not running, for instance if the machine has failed to start and you wish to reinstall the operating system

Board.setPreferredSize(new Dimension(x, y));
.
.
//Main.add(Board, BorderLayout.CENTER);
Main.add(Board, BorderLayout.CENTER);
Main.setLocations(x, y);
Main.pack();
Main.setVisible(true);

hi friend in this case you can use the

AppendDataBound="true"

and after this use the list item. for e.g.:

<asp:DropDownList ID="DropDownList1" runat="server" AppendDataBoundItems="true">
    <asp:ListItem Text="--Select One--" Value="" />   
</asp:DropDownList>

but the problem in this is after second time select data are append with old data.

To just get everything done goto Window>Preferences>General and goto theme menu and change it... Then re-start to apply...

- Another Update -

Since Twitter Bootstrap version 2.0 - which saw the removal of the .container-fluid class - it has not been possible to implement a two column fixed-fluid layout using just the bootstrap classes - however I have updated my answer to include some small CSS changes that can be made in your own CSS code that will make this possible

It is possible to implement a fixed-fluid structure using the CSS found below and slightly modified HTML code taken from the Twitter Bootstrap Scaffolding : layouts documentation page:

HTML

<div class="container-fluid fill">
    <div class="row-fluid">
        <div class="fixed">  <!-- we want this div to be fixed width -->
            ...
        </div>
        <div class="hero-unit filler">  <!-- we have removed spanX class -->
            ...
        </div>
    </div>
</div>

CSS

/* CSS for fixed-fluid layout */

.fixed {
    width: 150px;  /* the fixed width required */
    float: left;
}

.fixed + div {
     margin-left: 150px;  /* must match the fixed width in the .fixed class */
     overflow: hidden;
}


/* CSS to ensure sidebar and content are same height (optional) */

html, body {
    height: 100%;
}

.fill { 
    min-height: 100%;
    position: relative;
}

.filler:after{
    background-color:inherit;
    bottom: 0;
    content: "";
    height: auto;
    min-height: 100%;
    left: 0;
    margin:inherit;
    right: 0;
    position: absolute;
    top: 0;
    width: inherit;
    z-index: -1;  
}

I have kept the answer below - even though the edit to support 2.0 made it a fluid-fluid solution - as it explains the concepts behind making the sidebar and content the same height (a significant part of the askers question as identified in the comments)

Important

Answer below is fluid-fluid

Update As pointed out by @JasonCapriotti in the comments, the original answer to this question (created for v1.0) did not work in Bootstrap 2.0. For this reason, I have updated the answer to support Bootstrap 2.0

To ensure that the main content fills at least 100% of the screen height, we need to set the height of the html and body to 100% and create a new css class called .fill which has a minimum-height of 100%:

html, body {
    height: 100%;
}

.fill { 
    min-height: 100%;
}

We can then add the .fill class to any element that we need to take up 100% of the sceen height. In this case we add it to the first div:

<div class="container-fluid fill">
    ...
</div>

To ensure that the Sidebar and the Content columns have the same height is very difficult and unnecessary. Instead we can use the ::after pseudo selector to add a filler element that will give the illusion that the two columns have the same height:

.filler::after {
    background-color: inherit;
    bottom: 0;
    content: "";
    right: 0;
    position: absolute;
    top: 0;
    width: inherit;
    z-index: -1;  
}

To make sure that the .filler element is positioned relatively to the .fill element we need to add position: relative to .fill:

.fill { 
    min-height: 100%;
    position: relative;
}

And finally add the .filler style to the HTML:

HTML

<div class="container-fluid fill">
    <div class="row-fluid">
        <div class="span3">
            ...
        </div>
        <div class="span9 hero-unit filler">
            ...
        </div>
    </div>
</div>

Notes

• If you need the element on the left of the page to be the filler then you need to change right: 0 to left: 0.

1. Go to IIS, (sites)
2. Right click on project inside the sites.enter image description here

and click on edit permission.

3. Go to security.

4. click on edit button.

5. click add button. type COMPUTER_NAME\IIS_USERS

   or

6. click advance.

7. click find now button.

   and there is option to choose. choose IIS_USERS and click ok...ok....ok .

In the examples below the client is the browser and the server is the webserver hosting the website.

Before you can understand these technologies, you have to understand classic HTTP web traffic first.

Regular HTTP:

1. A client requests a webpage from a server.
2. The server calculates the response
3. The server sends the response to the client.

Ajax Polling:

1. A client requests a webpage from a server using regular HTTP (see HTTP above).
2. The client receives the requested webpage and executes the JavaScript on the page which requests a file from the server at regular intervals (e.g. 0.5 seconds).
3. The server calculates each response and sends it back, just like normal HTTP traffic.

Ajax Long-Polling:

1. A client requests a webpage from a server using regular HTTP (see HTTP above).
2. The client receives the requested webpage and executes the JavaScript on the page which requests a file from the server.
3. The server does not immediately respond with the requested information but waits until there's new information available.
4. When there's new information available, the server responds with the new information.
5. The client receives the new information and immediately sends another request to the server, re-starting the process.

HTML5 Server Sent Events (SSE) / EventSource:

1. A client requests a webpage from a server using regular HTTP (see HTTP above).
2. The client receives the requested webpage and executes the JavaScript on the page which opens a connection to the server.

3. The server sends an event to the client when there's new information available.

   • Real-time traffic from server to client, mostly that's what you'll need
   • You'll want to use a server that has an event loop
   • Connections with servers from other domains are only possible with correct CORS settings
   • If you want to read more, I found these very useful: (article), (article), (article), (tutorial).

HTML5 Websockets:

1. A client requests a webpage from a server using regular http (see HTTP above).
2. The client receives the requested webpage and executes the JavaScript on the page which opens a connection with the server.

3. The server and the client can now send each other messages when new data (on either side) is available.

   • Real-time traffic from the server to the client and from the client to the server
   • You'll want to use a server that has an event loop
   • With WebSockets it is possible to connect with a server from another domain.
   • It is also possible to use a third party hosted websocket server, for example Pusher or others. This way you'll only have to implement the client side, which is very easy!
   • If you want to read more, I found these very useful: (article), (article) (tutorial).

Comet:

Comet is a collection of techniques prior to HTML5 which use streaming and long-polling to achieve real time applications. Read more on wikipedia or this article.

Now, which one of them should I use for a realtime app (that I need to code). I have been hearing a lot about websockets (with socket.io [a node.js library]) but why not PHP ?

You can use PHP with WebSockets, check out Ratchet.

This depends on what's actually being added by the pseudoselectors. In your situation, setting content to "" will get rid of it, but if you're setting borders or backgrounds or whatever, you need to zero those out specifically. As far as I know, there's no one cure-all for removing everything about a before/after element regardless of what it is.

simply: document.cookie="name=value;path=/";

There is a negative point to it

Now, the cookie will be available to all directories on the domain it is set from. If the website is just one of many at that domain, it’s best not to do this because everyone else will also have access to your cookie information.

Yet another variation on the theme:

sudo bash <<EOF
ls -hal /root/ > /root/test.out
EOF

Or of course:

echo 'ls -hal /root/ > /root/test.out' | sudo bash

They have the (tiny) advantage that you don't need to remember any arguments to sudo or sh/bash

You can use the CURDATE() and DATE_SUB() functions to achieve this:

SELECT URLX, COUNT(URLx) AS Count
FROM ExternalHits
WHERE datex BETWEEN DATE_SUB(CURDATE(), INTERVAL 7 DAY) AND CURDATE()    
GROUP BY URLx
ORDER BY Count DESC; 

Javascript:

window.sumInputs = function() {
    var inputs = document.getElementsByTagName('input'),
        result = document.getElementById('total'),
        sum = 0;            

    for(var i=0; i<inputs.length; i++) {
        var ip = inputs[i];

        if (ip.name && ip.name.indexOf("total") < 0) {
            sum += parseInt(ip.value) || 0;
        }

    }

    result.value = sum;
}?   

Html:

Qty1 : <input type="text" name="qty1" id="qty"/><br>
Qty2 : <input type="text" name="qty2" id="qty"/><br>
Qty3 : <input type="text" name="qty3" id="qty"/><br>
Qty4 : <input type="text" name="qty4" id="qty"/><br>
Qty5 : <input type="text" name="qty5" id="qty"/><br>
Qty6 : <input type="text" name="qty6" id="qty"/><br
Qty7 : <input type="text" name="qty7" id="qty"/><br>
Qty8 : <input type="text" name="qty8" id="qty"/><br>
<br><br>
Total : <input type="text" name="total" id="total"/>

<a href="javascript:sumInputs()">Sum</a>

I want to be able to create a variable name containing the first argument of the command

script.sh file:

#!/usr/bin/env bash
function grep_search() {
  eval $1=$(ls | tail -1)
}

Test:

$ source script.sh
$ grep_search open_box
$ echo $open_box
script.sh

As per help eval:

Execute arguments as a shell command.

You may also use Bash ${!var} indirect expansion, as already mentioned, however it doesn't support retrieving of array indices.

For further read or examples, check BashFAQ/006 about Indirection.

We are not aware of any trick that can duplicate that functionality in POSIX or Bourne shells without eval, which can be difficult to do securely. So, consider this a use at your own risk hack.

However, you should re-consider using indirection as per the following notes.

Normally, in bash scripting, you won't need indirect references at all. Generally, people look at this for a solution when they don't understand or know about Bash Arrays or haven't fully considered other Bash features such as functions.

Putting variable names or any other bash syntax inside parameters is frequently done incorrectly and in inappropriate situations to solve problems that have better solutions. It violates the separation between code and data, and as such puts you on a slippery slope toward bugs and security issues. Indirection can make your code less transparent and harder to follow.

tl;dr Set the editor to something nicer, like Sublime or Atom

Here nice is used in the meaning of an editor you like or find more user friendly.

The underlying problem is that Git by default uses an editor that is too unintuitive to use for most people: Vim. Now, don't get me wrong, I love Vim, and while you could set some time aside (like a month) to learn Vim and try to understand why some people think Vim is the greatest editor in existence, there is a quicker way of fixing this problem :-)

The fix is not to memorize cryptic commands, like in the accepted answer, but configuring Git to use an editor that you like and understand! It's really as simple as configuring either of these options

1. the git config setting core.editor (per project, or globally)
2. the VISUAL or EDITOR environment variable (this works for other programs as well)

I'll cover the first option for a couple of popular editors, but GitHub has an excellent guide on this for many editors as well.

To use Atom

Straight from its docs, enter this in a terminal: git config --global core.editor "atom --wait"

Git normally wait for the editor command to finish, but since Atom forks to a background process immediately, this won't work, unless you give it the --wait option.

To use Sublime Text

For the same reasons as in the Atom case, you need a special flag to signal to the process that it shouldn't fork to the background:

git config --global core.editor "subl -n -w"

In my opinion the simplest way for an indexed array would be simply:

    if ($array) {
      //Array is not empty...  
    }

An 'if' condition on the array would evaluate to true if the array is not empty and false if the array is empty. This is not applicable to associative arrays.

To understand how PreparedStatement prevents SQL Injection, we need to understand phases of SQL Query execution.

1. Compilation Phase. 2. Execution Phase.

Whenever SQL server engine receives a query, it has to pass through below phases,

1. Parsing and Normalization Phase: In this phase, Query is checked for syntax and semantics. It checks whether references table and columns used in query exist or not. It also has many other tasks to do, but let's not go in detail.

2. Compilation Phase: In this phase, keywords used in query like select, from, where etc are converted into format understandable by machine. This is the phase where query is interpreted and corresponding action to be taken is decided. It also has many other tasks to do, but let's not go in detail.

3. Query Optimization Plan: In this phase, Decision Tree is created for finding the ways in which query can be executed. It finds out the number of ways in which query can be executed and the cost associated with each way of executing Query. It chooses the best plan for executing a query.

4. Cache: Best plan selected in Query optimization plan is stored in cache, so that whenever next time same query comes in, it doesn't have to pass through Phase 1, Phase 2 and Phase 3 again. When next time query come in, it will be checked directly in Cache and picked up from there to execute.

5. Execution Phase: In this phase, supplied query gets executed and data is returned to user as ResultSet object.

Behaviour of PreparedStatement API on above steps

1. PreparedStatements are not complete SQL queries and contain placeholder(s), which at run time are replaced by actual user-provided data.

2. Whenever any PreparedStatment containing placeholders is passed in to SQL Server engine, It passes through below phases

   1. Parsing and Normalization Phase
   2. Compilation Phase
   3. Query Optimization Plan
   4. Cache (Compiled Query with placeholders are stored in Cache.)

UPDATE user set username=? and password=? WHERE id=?

3. Above query will get parsed, compiled with placeholders as special treatment, optimized and get Cached. Query at this stage is already compiled and converted in machine understandable format. So we can say that Query stored in cache is Pre-Compiled and only placeholders need to be replaced with user-provided data.

4. Now at run-time when user-provided data comes in, Pre-Compiled Query is picked up from Cache and placeholders are replaced with user-provided data.

(Remember, after place holders are replaced with user data, final query is not compiled/interpreted again and SQL Server engine treats user data as pure data and not a SQL that needs to be parsed or compiled again; that is the beauty of PreparedStatement.)

If the query doesn't have to go through compilation phase again, then whatever data replaced on the placeholders are treated as pure data and has no meaning to SQL Server engine and it directly executes the query.

Note: It is the compilation phase after parsing phase, that understands/interprets the query structure and gives meaningful behavior to it. In case of PreparedStatement, query is compiled only once and cached compiled query is picked up all the time to replace user data and execute.

Due to one time compilation feature of PreparedStatement, it is free of SQL Injection attack.

You can get detailed explanation with example here: https://javabypatel.blogspot.com/2015/09/how-prepared-statement-in-java-prevents-sql-injection.html

Use:

List<String> x = new ArrayList<>(Arrays.asList("xyz", "abc"));

If you don't want to add new elements to the list later, you can also use (Arrays.asList returns a fixed-size list):

List<String> x = Arrays.asList("xyz", "abc");

Note: you can also use a static import if you like, then it looks like this:

import static java.util.Arrays.asList;

...

List<String> x = new ArrayList<>(asList("xyz", "abc"));

or

List<String> x = asList("xyz", "abc");

If multiple characters are bound inside a single integer/long, as was my issue:

s = '0123456789'
nchars = len(s)
# string to int or long. Type depends on nchars
x = sum(ord(s[byte])<<8*(nchars-byte-1) for byte in range(nchars))
# int or long to string
''.join(chr((x>>8*(nchars-byte-1))&0xFF) for byte in range(nchars))

Yields '0123456789' and x = 227581098929683594426425L

You just need to use the Gradle Application plugin:

apply plugin:'application'
mainClassName = "org.gradle.sample.Main"

And then simply gradle run.

As Teresa points out, you can also configure mainClassName as a system property and run with a command line argument.

i know this is an old thread but i came up with this today

var timer       = []; //creates a empty array called timer to store timer instances
var afterTimer = function(timerName, interval, callback){
    window.clearTimeout(timer[timerName]); //clear the named timer if exists
    timer[timerName] = window.setTimeout(function(){ //creates a new named timer 
        callback(); //executes your callback code after timer finished
    },interval); //sets the timer timer
}

and you invoke using

afterTimer('<timername>string', <interval in milliseconds>int, function(){
   your code here
});

If you are using webjars. You need to add this in your configure method: http.authorizeRequests().antMatchers("/webjars/**").permitAll();

Make sure this is the first statement. For example:

@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests().antMatchers("/webjars/**").permitAll();
        http.authorizeRequests().anyRequest().authenticated();
         http.formLogin()
         .loginPage("/login")
         .failureUrl("/login?error")
         .usernameParameter("email")
         .permitAll()
         .and()
         .logout()
         .logoutUrl("/logout")
         .deleteCookies("remember-me")
         .logoutSuccessUrl("/")
         .permitAll()
         .and()
         .rememberMe();
    }

You will also need to have this in order to have webjars enabled:

@Configuration
    public class MvcConfig extends WebMvcConfigurerAdapter {
        ...
        @Override
        public void addResourceHandlers(ResourceHandlerRegistry registry) {
                registry.addResourceHandler("/webjars/**").addResourceLocations("classpath:/META-INF/resources/webjars/");
        }
        ...
    }

Using some of the other methods You may enter a conflict where multiple IP adresses is defined on the system. This line always gets the IP address by default used.

ip route get 8.8.8.8 | head -1 | awk '{print $7}'

It depends upon the version of OS - for me it works with Command + 7

In Android Manifest File, put attribute for your <activity> that android:screenOrientation="portrait"

"final" guarantees that a variable must be initialized before end of object initializer code. Likewise "static final" guarantees that a variable will be initialized by the end of class initialization code. Omitting the "static" from your initialization code turns it into object initialization code; thus your variable no longer satisfies its guarantees.

Go to File > Preferences > Settings (or press Ctrl+,) then click the leftmost icon in the top right corner, "Open Settings (JSON)"

In the JSON settings window, add this (within the curly braces {}):

"terminal.integrated.shell.windows": "C:\\WINDOWS\\System32\\bash.exe"`

(Here you can put any other custom settings you want as well)

Checkout that path to make sure your bash.exe file is there otherwise find out where it is and point to that path instead.

Now if you open a new terminal window in VS Code, it should open with bash instead of PowerShell.

What's wrong with the printStacktrace() method provided by Throwable (and thus every exception)? It shows all the info you requested, including the type, message, and stack trace of the root exception and all (nested) causes. In Java 7, it even shows you the information about "supressed" exceptions that might occur in a try-with-resources statement.

Of course you wouldn't want to write to System.err, which the no-argument version of the method does, so instead use one of the available overloads.

In particular, if you just want to get a String:

  Exception e = ...
  StringWriter sw = new StringWriter();
  e.printStackTrace(new PrintWriter(sw));
  String exceptionDetails = sw.toString();

If you happen to use the great Guava library, it provides a utility method doing this: com.google.common.base.Throwables#getStackTraceAsString(Throwable).

Always use library. Never use require.

In a nutshell, this is because, when using require, your code might yield different, erroneous results, without signalling an error. This is rare but not hypothetical! Consider this code, which yields different results depending on whether {dplyr} can be loaded:

require(dplyr)

x = data.frame(y = seq(100))
y = 1
filter(x, y == 1)

This can lead to subtly wrong results. Using library instead of require throws an error here, signalling clearly that something is wrong. This is good.

It also makes debugging all other failures more difficult: If you require a package at the start of your script and use its exports in line 500, you’ll get an error message “object ‘foo’ not found” in line 500, rather than an error “there is no package called ‘bla’”.

The only acceptable use case of require is when its return value is immediately checked, as some of the other answers show. This is a fairly common pattern but even in these cases it is better (and recommended, see below) to instead separate the existence check and the loading of the package. That is: use requireNamespace instead of require in these cases.

More technically, require actually calls library internally (if the package wasn’t already attached — require thus performs a redundant check, because library also checks whether the package was already loaded). Here’s a simplified implementation of require to illustrate what it does:

require = function (package) {
    already_attached = paste('package:', package) %in% search()
    if (already_attached) return(TRUE)
    maybe_error = try(library(package, character.only = TRUE)) 
    success = ! inherits(maybe_error, 'try-error')
    if (! success) cat("Failed")
    success
}

Experienced R developers agree:

Yihui Xie, author of {knitr}, {bookdown} and many other packages says:

Ladies and gentlemen, I've said this before: require() is the wrong way to load an R package; use library() instead

Hadley Wickham, author of more popular R packages than anybody else, says

Use library(x) in data analysis scripts. […] You never need to use require() (requireNamespace() is almost always better)

No need for external plugins. In the Export JAR dialog, make sure you select all the necessary resources you want to export. By default, there should be no problem exporting other resource files as well (pictures, configuration files, etc...), see screenshot below.

This is certainly something that has a lot of traps. I was working with Paolo Bergantino's answer, and realising that even that has some limitations. I found working with string representations of dates a good place to quickly find some of the main problems. Start with an input string like this: '12-2-2019 5:1:48.670'

and set up Paolo's function like this:

function count(re, str) {
    if (typeof re !== "string") {
        return 0;
    }
    re = (re === '.') ? ('\\' + re) : re;
    var cre = new RegExp(re, 'g');
    return ((str || '').match(cre) || []).length;
}

I wanted the regular expression to be passed in, so that the function is more reusable, secondly, I wanted the parameter to be a string, so that the client doesn't have to make the regex, but simply match on the string, like a standard string utility class method.

Now, here you can see that I'm dealing with issues with the input. With the following:

if (typeof re !== "string") {
    return 0;
}

I am ensuring that the input isn't anything like the literal 0, false, undefined, or null, none of which are strings. Since these literals are not in the input string, there should be no matches, but it should match '0', which is a string.

With the following:

re = (re === '.') ? ('\\' + re) : re;

I am dealing with the fact that the RegExp constructor will (I think, wrongly) interpret the string '.' as the all character matcher \.\

Finally, because I am using the RegExp constructor, I need to give it the global 'g' flag so that it counts all matches, not just the first one, similar to the suggestions in other posts.

I realise that this is an extremely late answer, but it might be helpful to someone stumbling along here. BTW here's the TypeScript version:

function count(re: string, str: string): number {
    if (typeof re !== 'string') {
        return 0;
    }
    re = (re === '.') ? ('\\' + re) : re;
    const cre = new RegExp(re, 'g');    
    return ((str || '').match(cre) || []).length;
}

I would like to expand on Riki_tiki_tavi's answer and get the data out there. I have created a datediff function that does almost everything sql server does. So that way we can take into account any unit.

create function datediff(units character varying, start_t timestamp without time zone, end_t timestamp without time zone) returns integer
language plpgsql
 as
 $$
DECLARE
 diff_interval INTERVAL; 
 diff INT = 0;
 years_diff INT = 0;
BEGIN
 IF units IN ('yy', 'yyyy', 'year', 'mm', 'm', 'month') THEN
   years_diff = DATE_PART('year', end_t) - DATE_PART('year', start_t);

   IF units IN ('yy', 'yyyy', 'year') THEN
     -- SQL Server does not count full years passed (only difference between year parts)
     RETURN years_diff;
   ELSE
     -- If end month is less than start month it will subtracted
     RETURN years_diff * 12 + (DATE_PART('month', end_t) - DATE_PART('month', start_t)); 
   END IF;
 END IF;

 -- Minus operator returns interval 'DDD days HH:MI:SS'  
 diff_interval = end_t - start_t;

 diff = diff + DATE_PART('day', diff_interval);

 IF units IN ('wk', 'ww', 'week') THEN
   diff = diff/7;
   RETURN diff;
 END IF;

 IF units IN ('dd', 'd', 'day') THEN
   RETURN diff;
 END IF;

 diff = diff * 24 + DATE_PART('hour', diff_interval); 

 IF units IN ('hh', 'hour') THEN
    RETURN diff;
 END IF;

 diff = diff * 60 + DATE_PART('minute', diff_interval);

 IF units IN ('mi', 'n', 'minute') THEN
    RETURN diff;
 END IF;

 diff = diff * 60 + DATE_PART('second', diff_interval);

 RETURN diff;
END;

I have been reading about Android Service very recently and got a chance to deep dive on it. I have encountered a service leak, for my situation it happened because I had an unbound Service which was starting a bound Service, but in this my unbound Service is replaced by an Activity.

So when I was stopping my unbound Service by using stopSelf() the leak occurred, the reason was I was stopping the parent service without unbinding the bound service. Now the bound service is running and it doesn't know to whom does it belong.

The easy and straight forward fix is you should call unbindService(YOUR_SERVICE); in your onDestroy() function of your parent Activity/Service. This way the lifecycle will ensure that your bound services are stopped or cleaned up before your parent Activity/Services go down.

There is one other variation of this problem. Sometimes in your bound service you want certain functions to work only if the service is bound so we end up putting a bound flag in the onServiceConnected like:

public void onServiceConnected(ComponentName name, IBinder service) {
            bounded = true;
            // code here
        }

This works fine till here but the problem comes when we treat onServiceDisconnected function as a callback for unbindService function call, this by documentation is only called when a service is killed or crashed. And you will never get this callback in the same thread. Hence, we end up doing something like:

public void onServiceDisconnected(ComponentName name) {
            bounded = false;
        }

Which creates major bug in the code because our bound flag never gets reset to false and when this service is connected back again most of the times it is true. So in order to avoid this scenario you should set the bound to false the moment you are calling unbindService.

This is cover in more detail in Erik's blog.

Hope who ever came here got his curiosity satisfied.

You have to declare the array variable as an array:

Both pandas and matplotlib.dates use matplotlib.units for locating the ticks.

But while matplotlib.dates has convenient ways to set the ticks manually, pandas seems to have the focus on auto formatting so far (you can have a look at the code for date conversion and formatting in pandas).

So for the moment it seems more reasonable to use matplotlib.dates (as mentioned by @BrenBarn in his comment).

import numpy as np
import pandas as pd
import matplotlib.pyplot as plt 
import matplotlib.dates as dates

idx = pd.date_range('2011-05-01', '2011-07-01')
s = pd.Series(np.random.randn(len(idx)), index=idx)

fig, ax = plt.subplots()
ax.plot_date(idx.to_pydatetime(), s, 'v-')
ax.xaxis.set_minor_locator(dates.WeekdayLocator(byweekday=(1),
                                                interval=1))
ax.xaxis.set_minor_formatter(dates.DateFormatter('%d\n%a'))
ax.xaxis.grid(True, which="minor")
ax.yaxis.grid()
ax.xaxis.set_major_locator(dates.MonthLocator())
ax.xaxis.set_major_formatter(dates.DateFormatter('\n\n\n%b\n%Y'))
plt.tight_layout()
plt.show()

Your error shows you are not compiling file with the definition of the insert function. Update your command to include the file which contains the definition of that function and it should work.

There are several ways to achieve your desired result, this my humble way of doing it:

Let the element hold its previous value, so add an attribute 'previousValue'.

<select id="mySelect" previousValue=""></select>

Once initialized, 'previousValue' could now be used as an attribute. In JS, to access the previousValue of this select:

$("#mySelect").change(function() {console.log($(this).attr('previousValue'));.....; $(this).attr('previousValue', this.value);}

After you are done using 'previousValue', update the attribute to current value.

Its simple, just make sure the data type in your columns are the same. For e.g. I faced the same error, that and an another error:

Error in contrasts<-(*tmp*, value = contr.funs[1 + isOF[nn]]) : contrasts can be applied only to factors with 2 or more levels

So, I went back to my excel file or csv file, set a filter on the variable throwing me an error and checked if the distinct datatypes are the same. And... Oh! it had numbers and strings, so I converted numbers to string and it worked just fine for me.

The simple solution is to just remap coordinates from the original to the final image, copying pixels from one coordinate space to the other, rounding off as necessary -- which may result in some pixels being copied several times adjacent to each other, and other pixels being skipped, depending on whether you're stretching or shrinking (or both) in either dimension. Make sure your copying iterates through the destination space, so all pixels are covered there even if they're painted more than once, rather than thru the source which may skip pixels in the output.

The better solution involves calculating the corresponding source coordinate without rounding, and then using its fractional position between pixels to compute an appropriate average of the (typically) four pixels surrounding that location. This is essentially a filtering operation, so you lose some resolution -- but the result looks a LOT better to the human eye; it does a much better job of retaining small details and avoids creating straight-line artifacts which humans find objectionable.

Note that the same basic approach can be used to remap flat images onto any other shape, including 3D surface mapping.

In iTunes 11 you can go to the view menu, and "Show Sidebar", this will give you the sidebar, that you can drag 'n drop to.

You'll drag 'n drop to the open area that will be near the bottom of the sidebar (I'm typically doing this with both an IPA and a provisioning profile). After you do that, there will be an apps menu that appears in the sidebar with your app in it. Click on that, and you'll see your application in the main view. You can then drag your application from there to your device. Below, please find a video (it's private, so you'll need the URL) that outlines the steps visually: http://youtube.com/watch?v=0ACq4CRpEJ8&feature=youtu.be

It comes from the idea that you often want to apply something to an object. The more accurate example is the one of factories. When you have a factory, you want to apply parameter to it to create an object.

Scala guys thought that, as it occurs in many situation, it could be nice to have a shortcut to call apply. Thus when you give parameters directly to an object, it's desugared as if you pass these parameters to the apply function of that object:

class MyAdder(x: Int) {
  def apply(y: Int) = x + y
}

val adder = new MyAdder(2)
val result = adder(4) // equivalent to x.apply(4)

It's often use in companion object, to provide a nice factory method for a class or a trait, here is an example:

trait A {
  val x: Int
  def myComplexStrategy: Int
}

object A {
  def apply(x: Int): A = new MyA(x)

  private class MyA(val x: Int) extends A {
    val myComplexStrategy = 42
  }
}

From the scala standard library, you might look at how scala.collection.Seq is implemented: Seq is a trait, thus new Seq(1, 2) won't compile but thanks to companion object and apply, you can call Seq(1, 2) and the implementation is chosen by the companion object.

You can use two for loops in same line by using zip function

Code:

list1 = ['Abbas', 'Ali', 'Usman']
list2 = ['Kamran', 'Asgar', 'Hamza', 'Umer']
list3 = []
for i,j in zip(list1,list2):
    list3.append(i)
    list3.append(j)
print(list3)

Output:

['Abbas', 'Kamran', 'Ali', 'Asgar', 'Usman', 'Hamza']

So, by using zip function, we can use two for loops or we can iterate two lists in same row.

I found that the following code, when inserted into the site's footer, worked well enough:

<script type="text/javascript">
$("#nav-ask").remove();
</script>

This may or may not require jquery. The site I'm editing has jquery, but unfortunately I'm no javascripter, so I only have a limited knowledge of what's going on here, and the requirements of this code snippet...

While I agree that the accepted answer is usually the best solution and definitely easier to use, I noticed no one displayed the proper usage of the iterator. So here is a quick example:

Iterator<Object> it = arrayList.iterator();
while(it.hasNext())
{
    Object obj = it.next();
    //Do something with obj
}

You can also use jQuery('.class-name').attr("href"), in my case it works better.

Here more information: "jQuery(...)" instead of "$(...)"

You can use the AND or OR operators, depending on what you want the search to return.

SELECT title FROM pages WHERE my_col LIKE %$param1% AND another_col LIKE %$param2%;

Both clauses have to match for a record to be returned. Alternatively:

SELECT title FROM pages WHERE my_col LIKE %$param1% OR another_col LIKE %$param2%;

If either clause matches then the record will be returned.

For more about what you can do with MySQL SELECT queries, try the documentation.

Fast-forward merging makes sense for short-lived branches, but in a more complex history, non-fast-forward merging may make the history easier to understand, and make it easier to revert a group of commits.

Warning: Non-fast-forwarding has potential side effects as well. Please review https://sandofsky.com/blog/git-workflow.html, avoid the 'no-ff' with its "checkpoint commits" that break bisect or blame, and carefully consider whether it should be your default approach for master.

^{(From nvie.com, Vincent Driessen, post "A successful Git branching model")}

Incorporating a finished feature on develop

Finished features may be merged into the develop branch to add them to the upcoming release:

$ git checkout develop
Switched to branch 'develop'
$ git merge --no-ff myfeature
Updating ea1b82a..05e9557
(Summary of changes)
$ git branch -d myfeature
Deleted branch myfeature (was 05e9557).
$ git push origin develop

The --no-ff flag causes the merge to always create a new commit object, even if the merge could be performed with a fast-forward. This avoids losing information about the historical existence of a feature branch and groups together all commits that together added the feature.

Jakub Narebski also mentions the config merge.ff:

By default, Git does not create an extra merge commit when merging a commit that is a descendant of the current commit. Instead, the tip of the current branch is fast-forwarded.
When set to false, this variable tells Git to create an extra merge commit in such a case (equivalent to giving the --no-ff option from the command line).
When set to 'only', only such fast-forward merges are allowed (equivalent to giving the --ff-only option from the command line).

The fast-forward is the default because:

• short-lived branches are very easy to create and use in Git
• short-lived branches often isolate many commits that can be reorganized freely within that branch
• those commits are actually part of the main branch: once reorganized, the main branch is fast-forwarded to include them.

But if you anticipate an iterative workflow on one topic/feature branch (i.e., I merge, then I go back to this feature branch and add some more commits), then it is useful to include only the merge in the main branch, rather than all the intermediate commits of the feature branch.

In this case, you can end up setting this kind of config file:

[branch "master"]
# This is the list of cmdline options that should be added to git-merge 
# when I merge commits into the master branch.

# The option --no-commit instructs git not to commit the merge
# by default. This allows me to do some final adjustment to the commit log
# message before it gets commited. I often use this to add extra info to
# the merge message or rewrite my local branch names in the commit message
# to branch names that are more understandable to the casual reader of the git log.

# Option --no-ff instructs git to always record a merge commit, even if
# the branch being merged into can be fast-forwarded. This is often the
# case when you create a short-lived topic branch which tracks master, do
# some changes on the topic branch and then merge the changes into the
# master which remained unchanged while you were doing your work on the
# topic branch. In this case the master branch can be fast-forwarded (that
# is the tip of the master branch can be updated to point to the tip of
# the topic branch) and this is what git does by default. With --no-ff
# option set, git creates a real merge commit which records the fact that
# another branch was merged. I find this easier to understand and read in
# the log.

mergeoptions = --no-commit --no-ff

The OP adds in the comments:

I see some sense in fast-forward for [short-lived] branches, but making it the default action means that git assumes you... often have [short-lived] branches. Reasonable?

Jefromi answers:

I think the lifetime of branches varies greatly from user to user. Among experienced users, though, there's probably a tendency to have far more short-lived branches.

To me, a short-lived branch is one that I create in order to make a certain operation easier (rebasing, likely, or quick patching and testing), and then immediately delete once I'm done.
That means it likely should be absorbed into the topic branch it forked from, and the topic branch will be merged as one branch. No one needs to know what I did internally in order to create the series of commits implementing that given feature.

More generally, I add:

it really depends on your development workflow:

• if it is linear, one branch makes sense.
• If you need to isolate features and work on them for a long period of time and repeatedly merge them, several branches make sense.

See "When should you branch?"

Actually, when you consider the Mercurial branch model, it is at its core one branch per repository (even though you can create anonymous heads, bookmarks and even named branches)
See "Git and Mercurial - Compare and Contrast".

Mercurial, by default, uses anonymous lightweight codelines, which in its terminology are called "heads".
Git uses lightweight named branches, with injective mapping to map names of branches in remote repository to names of remote-tracking branches.
Git "forces" you to name branches (well, with the exception of a single unnamed branch, which is a situation called a "detached HEAD"), but I think this works better with branch-heavy workflows such as topic branch workflow, meaning multiple branches in a single repository paradigm.

It depends on the package. If the Makefile is generated by GNU autotools (./configure) you can usually set the target location like so:

./configure --prefix=/somewhere/else/than/usr/local

If the Makefile is not generated by autotools, but distributed along with the software, simply open it up in an editor and change it. The install target directory is probably defined in a variable somewhere.

U can store any value in session like Session["FirstName"] = FirstNameTextBox.Text; but i will suggest u to take as static field in model assign value to it and u can access that field value any where in application. U don't need session. session should be avoided.

public class Employee
{
   public int UserId { get; set; }
   public string EmailAddress { get; set; }
   public static string FullName { get; set; }
}

on controller - Employee.FullName = "ABC"; Now u can access this full Name anywhere in application.

I actually found a better way to send files using HttpURLConnection using MultipartEntity

private static String multipost(String urlString, MultipartEntity reqEntity) {

        conn.setConnectTimeout(15000);
        conn.setRequestMethod("POST");
        conn.setUseCaches(false);
        conn.setDoInput(true);
        conn.setDoOutput(true);

        conn.setRequestProperty("Connection", "Keep-Alive");
        conn.addRequestProperty("Content-length", reqEntity.getContentLength()+"");
        conn.addRequestProperty(reqEntity.getContentType().getName(), reqEntity.getContentType().getValue());

        OutputStream os = conn.getOutputStream();
        reqEntity.writeTo(conn.getOutputStream());
        os.close();
        conn.connect();

        if (conn.getResponseCode() == HttpURLConnection.HTTP_OK) {
            return readStream(conn.getInputStream());
        }

    } catch (Exception e) {

    } catch (IOException e) {
        e.printStackTrace();
    } finally {
        if (reader != null) {
            try {
                reader.close();
            } catch (IOException e) {
                e.printStackTrace();
            }

Assuming you are uploading an image with bitmap data:

    Bitmap bitmap = ...;
    String filename = "filename.png";
    ByteArrayOutputStream bos = new ByteArrayOutputStream();
    bitmap.compress(Bitmap.CompressFormat.PNG, 100, bos);
    ContentBody contentPart = new ByteArrayBody(bos.toByteArray(), filename);

    MultipartEntity reqEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
    reqEntity.addPart("picture", contentPart);
    String response = multipost("http://server.com", reqEntity);

And Voila! Your post data will contain picture field along with the filename and path on your server.

For ex .. add class:

btn-lg - LARGE

btn-sm - SMALL

btn-xs - Very small

<button type=button class="btn btn-default btn-lg">
<span class="glyphicon glyphicon-star" aria-hidden=true></span> Star
</button> 

<button type=button class="btn btn-default">
<span class="glyphicon glyphicon-star" aria-hidden=true></span>Star
</button>

 <button type=button class="btn btn-default btn-sm">
<span class="glyphicon glyphicon-star" aria-hidden=true></span> Star
</button> 

<button type=button class="btn btn-default btn-xs">
<span class="glyphicon glyphicon-star" aria-hidden=true></span> Star
</button>

I had a similiar problem. All I needed to do was type store.load(); in the delete handler. There was no need to subsequently type grid.getView().refresh();.

Instead of all this you can also type store.remove(record) in the delete handler; - this ensures that the deleted record no longer shows on the grid.

Clear & Simple Instructions for Rails 5 & 6

• WARNING: You will lose data if you remove a column from your database. To proceed, see below:
• Warning: the below instructions are for trivial migrations. For complex migrations with e.g. millions and millions of rows, you will have to account for the possibility of failures, you will also have to think about how to optimise your migrations so that they run swiftly, and the possibility that users will use your app while the migration process is occurring. If you have multiple databases, or if anything is remotely complicated, then don't blame me if anything goes wrong!

1. Create a migration

Run the following command in your terminal:

rails generate migration remove_fieldname_from_tablename fieldname:fieldtype

Note: the table name should be in plural form as per rails convention.

Example:

In my case I want to remove the accepted column (a boolean value) from the quotes table:

rails g migration RemoveAcceptedFromQuotes accepted:boolean

See the documentation re: a convention when adding/removing fields to a table:

There is a special syntactic shortcut to generate migrations that add fields to a table.

rails generate migration add_fieldname_to_tablename fieldname:fieldtype

2. Check the migration

# db/migrate/20190122035000_remove_accepted_from_quotes.rb
class RemoveAcceptedFromQuotes < ActiveRecord::Migration[5.2]
  # with rails 5.2 you don't need to add a separate "up" and "down" method.
  def change
    remove_column :quotes, :accepted, :boolean
  end
end

3. Run the migration

rake db:migrate or rails db:migrate (they're both the same)

....And then you're off to the races!

If you want more control, you might want to check the TextPaint class. Here is how to use it:

final ClickableSpan clickableSpan = new ClickableSpan() {
    @Override
    public void onClick(final View textView) {
        //Your onClick code here
    }

    @Override
    public void updateDrawState(final TextPaint textPaint) {
        textPaint.setColor(yourContext.getResources().getColor(R.color.orange));
        textPaint.setUnderlineText(true);
    }
};

I cannot add comment so I will use this

in a vbs run that and have fun figuring out why the 2 give a result of 2

you can't trust round

 msgbox round(1.5) 'result to 2
 msgbox round(2.5) 'yes, result to 2 too

When my button's FlatStyle is set to system, it looks flat. And when it's set to popup, it only pops up when mouses over. Either is what I want. I want it to look sunken when checked and raised when unchecked and no change while mousing over (the button is really a checkbox but the checkbox's appearance property is set to button).

I end up setting the FlatStyle to flat and wrote a new Paint event handler.

 private void checkbox_paint(object sender, PaintEventArgs e)
        {
            CheckBox myCheckbox = (CheckBox)sender;
            Rectangle borderRectangle = myCheckbox.ClientRectangle;
            if (myCheckbox.Checked)
            {
                ControlPaint.DrawBorder3D(e.Graphics, borderRectangle,
                    Border3DStyle.Sunken);
            }
            else
            {
                ControlPaint.DrawBorder3D(e.Graphics, borderRectangle,
                    Border3DStyle.Raised);
            }
        }

I give a similar answer to this question: C# winforms button with solid border, like 3d Sorry for double posting.

cardeal's answer was really helpful. Took it a little further and figured it may help others some where down the line. Here is the fiddle:

https://jsfiddle.net/vtL5x0wh/

And the code:

<body ng-app="checkboxExample">
  <script>
  angular.module('checkboxExample', [])
    .controller('ExampleController', ['$scope', function($scope) {

    $scope.value0 = "none";
    $scope.value1 = "none";
    $scope.value2 = "none";
    $scope.value3 = "none";

    $scope.checkboxModel = {
        critical1: {selected: true, id: 'C1', error:'critical' , score:20},
        critical2: {selected: false, id: 'C2', error:'critical' , score:30},
        critical3: {selected: false, id: 'C3', error:'critical' , score:40},

       myClick : function($event) { 
          $scope.value0 = $event.selected;
          $scope.value1 = $event.id;
          $scope.value2 = $event.error;
          $scope.value3 = $event.score;
        }
    };

   }]);
</script>
<form name="myForm" ng-controller="ExampleController">
  <label>


    Value1:
    <input type="checkbox" ng-model="checkboxModel.critical1.selected" ng-change="checkboxModel.myClick(checkboxModel.critical1)">
  </label><br/>
  <label>Value2:
    <input type="checkbox" ng-model="checkboxModel.critical2.selected" ng-change="checkboxModel.myClick(checkboxModel.critical2)">
   </label><br/>
     <label>Value3:
    <input type="checkbox" ng-model="checkboxModel.critical3.selected" ng-change="checkboxModel.myClick(checkboxModel.critical3)">
   </label><br/><br/><br/><br/>
  <tt>selected = {{value0}}</tt><br/>
  <tt>id = {{value1}}</tt><br/>
  <tt>error = {{value2}}</tt><br/>
  <tt>score = {{value3}}</tt><br/>
 </form>

Had the same problem, I worked around it by changing ${java.home}/../bin/javafxpackager to ${java.home}/bin/javafxpackager

From now onwards after API 24, Uri.parse(filePath) won't work. You need to use this

final File videoFile = new File("path to your video file");
Uri fileUri = FileProvider.getUriForFile(mContext, "{yourpackagename}.fileprovider", videoFile);
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(fileUri, "video/*");
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);//DO NOT FORGET THIS EVER
startActivity(intent);

But before using this you need to understand how file provider works. Go to official document link to understand file provider better.

gethostname() using the IP from $_SERVER['REMOTE_ADDR'] while accessing the script remotely will return the IP of your internet connection, not your computer.

Another thing that can produce this error is when you are setting something equal to the return from a function, but forgot to actually return anything.

Example:

def foo(dict_of_dicts):
    for key, row in dict_of_dicts.items():
        for key, inner_row in row.items():
            Do SomeThing
    #Whoops, forgot to return all my stuff

return1, return2, return3 = foo(dict_of_dicts)

This is a little bit of a tough error to spot because the error can also be produced if the row variable happens to be None on one of the iterations. The way to spot it is that the trace fails on the last line and not inside the function.

If your only returning one variable from a function, I am not sure if the error would be produced... I suspect error "'NoneType' object is not iterable in Python" in this case is actually implying "Hey, I'm trying to iterate over the return values to assign them to these three variables in order but I'm only getting None to iterate over"

You can override the IIS default document setting using the web.config

<system.webServer>
    <defaultDocument>
      <files>
        <clear />
        <add value="DefaultPageToBeSet.aspx" />
      </files>
    </defaultDocument>
  </system.webServer>

Or using the IIS, refer the link for reference http://www.iis.net/configreference/system.webserver/defaultdocument

Well, I didn't like any of those answers, my solution of the same problem was to add this:<div>&nbsp;</div>. So in your scheme it would look like this (more or less), no style changes were necessary in my case:

-row-fluid-------------------------------------
+-span6----------+ +----span6----------+
|                | | +---div---+       |
| content        | | | & nbsp; |       |
| that           | | +---------+       |
| is tall        | | +-----div--------+|   
|                | | |short content   ||
|                | | +----------------+|
+----------------+ +-------------------+
-----------------------------------------------

First off, it is perfectly feasible to use R successfully for years and not need to know the answer to this question. R handles the differences between the (usual) numerics and integers for you in the background.

> is.numeric(1)

[1] TRUE

> is.integer(1)

[1] FALSE

> is.numeric(1L)

[1] TRUE

> is.integer(1L)

[1] TRUE

(Putting capital 'L' after an integer forces it to be stored as an integer.)

As you can see "integer" is a subset of "numeric".

> .Machine$integer.max

[1] 2147483647

> .Machine$double.xmax

[1] 1.797693e+308

Integers only go to a little more than 2 billion, while the other numerics can be much bigger. They can be bigger because they are stored as double precision floating point numbers. This means that the number is stored in two pieces: the exponent (like 308 above, except in base 2 rather than base 10), and the "significand" (like 1.797693 above).

Note that 'is.integer' is not a test of whether you have a whole number, but a test of how the data are stored.

One thing to watch out for is that the colon operator, :, will return integers if the start and end points are whole numbers. For example, 1:5 creates an integer vector of numbers from 1 to 5. You don't need to append the letter L.

> class(1:5)
[1] "integer"

Are there any performance benefits to using one over the other?

Keep in mind that there is no JavaScript engine yet that natively supports ES6 modules. You said yourself that you are using Babel. Babel converts import and export declaration to CommonJS (require/module.exports) by default anyway. So even if you use ES6 module syntax, you will be using CommonJS under the hood if you run the code in Node.

There are technical differences between CommonJS and ES6 modules, e.g. CommonJS allows you to load modules dynamically. ES6 doesn't allow this, but there is an API in development for that.

Since ES6 modules are part of the standard, I would use them.

Update 2020

Since Node v12, support for ES modules is enabled by default, but it's still experimental at the time of writing this. Files including node modules must either end in .mjs or the nearest package.json file must contain "type": "module". The Node documentation has a ton more information, also about interop between CommonJS and ES modules.

Performance-wise there is always the chance that newer features are not as well optimized as existing features. However, since module files are only evaluated once, the performance aspect can probably be ignored. In the end you have to run benchmarks to get a definite answer anyway.

ES modules can be loaded dynamically via the import() function. Unlike require, this returns a promise.
