It should be contained in the $_SERVER['REMOTE_ADDR'] variable.

I want a random number between 0 and 1, like 0.3452

random.random() is what you are looking for:

From python docs: random.random() Return the next random floating point number in the range [0.0, 1.0).

And, btw, Why your try didn't work?:

Your try was: random.randrange(0, 1)

From python docs: random.randrange() Return a randomly selected element from range(start, stop, step). This is equivalent to choice(range(start, stop, step)), but doesn’t actually build a range object.

So, what you are doing here, with random.randrange(a,b) is choosing a random element from range(a,b); in your case, from range(0,1), but, guess what!: the only element in range(0,1), is 0, so, the only element you can choose from range(0,1), is 0; that's why you were always getting 0 back.

Some safer alternatives to eval() and sympy.sympify().evalf()^*:

• asteval
• numexpr

^*SymPy sympify is also unsafe according to the following warning from the documentation.

Warning: Note that this function uses eval, and thus shouldn’t be used on unsanitized input.

Yes. Run ssh-add on the client machine. Then repeat command ssh-copy-id [email protected]

If message.value[] is string:

if message.value[0] in ('/', '\'):
    do_stuff()

If it not str

JSON has no functions as data types. You can only serialize strings, numbers, objects, arrays, and booleans (and null)

You could create your own toJson method, only passing the data that really has to be serialized:

Person.prototype.toJson = function() {
    return JSON.stringify({age: this.age});
};

Similar for deserializing:

Person.fromJson = function(json) {
    var data = JSON.parse(json); // Parsing the json string.
    return new Person(data.age);
};

The usage would be:

var serialize = p1.toJson();
var _p1 = Person.fromJson(serialize);
alert("Is old: " + _p1.isOld());

To reduce the amount of work, you could consider to store all the data that needs to be serialized in a special "data" property for each Person instance. For example:

function Person(age) {
    this.data = {
        age: age
    };
    this.isOld = function (){
        return this.data.age > 60 ? true : false;
    }
}

then serializing and deserializing is merely calling JSON.stringify(this.data) and setting the data of an instance would be instance.data = JSON.parse(json).

This would keep the toJson and fromJson methods simple but you'd have to adjust your other functions.

Side note:

You should add the isOld method to the prototype of the function:

Person.prototype.isOld = function() {}

Otherwise, every instance has it's own instance of that function which also increases memory.

I am in the same situation pointed out by malcook in his comment: unfortunately the answer by Thierry does not work with ggplot2 version 0.9.3.1.

png("figure_%d.png")
set.seed(2014)
library(ggplot2)
dataset <- data.frame(category = rep(LETTERS[1:5], 100),
    x = rnorm(500, mean = rep(1:5, 100)),
    y = rnorm(500, mean = rep(1:5, 100)))
dataset$fCategory <- factor(dataset$category)
subdata <- subset(dataset, category %in% c("A", "D", "E"))

ggplot(dataset, aes(x = x, y = y, colour = fCategory)) + geom_point()
ggplot(subdata, aes(x = x, y = y, colour = fCategory)) + geom_point()

Here it is the first figure:

and the second figure:

As we can see the colors do not stay fixed, for example E switches from magenta to blu.

As suggested by malcook in his comment and by hadley in his comment the code which uses limits works properly:

ggplot(subdata, aes(x = x, y = y, colour = fCategory)) +       
    geom_point() + 
    scale_colour_discrete(drop=TRUE,
        limits = levels(dataset$fCategory))

gives the following figure, which is correct:

list.insert(i, x)
Insert an item at a given position. The first argument is the index of the element before which to insert, so a.insert(0, x) inserts at the front of the list, and a.insert(len(a),x) is equivalent to a.append(x)

If you are using Java 7+, you may want to use NIO.2, e.g.:

❍ Code:

public static void main(String[] args) throws Exception {

    File file = new File("test.csv");

    List<String> lines = Files.readAllLines(file.toPath(), 
            StandardCharsets.UTF_8);

    for (String line : lines) {
        String[] array = line.split(",", -1);
        System.out.println(array[0]);
    }

}

❍ Output:

a
1RW
1RW
1RW
1RW
1RW
1RW
1R1W
1R1W
1R1W

To get the specific tag code try to create a new branch add get the tag code in it. I have done it by command : $git checkout -b newBranchName tagName

example how i made it , After i fill a Maximum length it will blur from my Field (and the Keyboard will disappear ) , if you have more than one field , you can just add the line that i add '//'

var MaxLength = 8;
    $(document).ready(function () {
        $('#MyTB').keyup(function () {
            if ($(this).val().length >= MaxLength) {
               $('#MyTB').blur();
             //  $('#MyTB2').focus();
         }
          }); });

No, you can't edit the connection string in the designer. The connection string is not part of the EDMX file it is just referenced value from the configuration file and probably because of that it is just readonly in the properties window.

Modifying configuration file is common task because you sometimes wants to make change without rebuilding the application. That is the reason why configuration files exist.

You really should implement prefersStatusBarHidden on your view controller(s):

Swift 3 and later

override var prefersStatusBarHidden: Bool {
    return true
}

Using lambdas instead of IDisposable.

I have never been thrilled with the whole using/IDisposable idea. The problem is that it requires the caller to:

• know that they must use IDisposable
• remember to use 'using'.

My new preferred method is to use a factory method and a lambda instead

Imagine I want to do something with a SqlConnection (something that should be wrapped in a using). Classically you would do

using (Var conn = Factory.MakeConnection())
{
     conn.Query(....);
}

New way

Factory.DoWithConnection((conn)=>
{
    conn.Query(...);
}

In the first case the caller could simply not use the using syntax. IN the second case the user has no choice. There is no method that creates a SqlConnection object, the caller must invoke DoWithConnection.

DoWithConnection looks like this

void DoWithConnection(Action<SqlConnection> action)
{
   using (var conn = MakeConnection())
   {
       action(conn);
   }
}

MakeConnection is now private

The difference is primarily in deployment. Web forward and reverse proxies all have the same underlying features. They accept requests for HTTP requests in various formats and provide a response, usually by accessing the origin or contact server.

Fully featured servers usually have access control, caching, and some link-mapping features.

A forward proxy is a proxy that is accessed by configuring the client machine. The client needs protocol support for proxy features (redirection, proxy authentication, etc.). The proxy is transparent to the user experience, but not to the application.

A reverse proxy is a proxy that is deployed as a web server and behaves like a web server, with the exception that instead of locally composing the content from programs and disk, it forwards the request to an origin server. From the client perspective it is a web server, so the user experience is completely transparent.

In fact, a single proxy instance can run as a forward and reverse proxy at the same time for different client populations.

You need to provide a selector with higher specificity than the one in Main.css. With that selector, set the values of the properties you want to their default, e.g.

body .c1 {
    height: auto;
}

There is no "default" value that will work for all properties, you need to look up what the default is for each one and use that.

You clone a repository with git clone [url]. Like so,

$ git clone https://github.com/libgit2/libgit2

Follow the below steps to sign the application in the android studio:-

1. First Go to Build->Generate Signed APK

   

2. Then Once you click on the Generate Signed APK then there is info dialog message appear.

   

3. Click on the Create New button if you don't have any keystore file. If you have click on the Choose Existing.

   

4. Once you click on the Create New button then now dialog box appear where you need to enter the keystore file info, other signing authority details.

   

5. Once you fill complete details then click on the Ok button then it redirect to this dialog.

   

6. Click on the Next button then check mark on the Run ProGuard and click on the finish. It generate the signed APK.

   

   

You can easily import your model and run this:

from models import User

# User is the name of table that has a column name
users = User.query.all()

for user in users:
    print user.name

please escape your variables when outputting (urlencode).

and you can’t just print an array, you have to build your url using a loop in some way

$url = 'http://example.com/index.php?'
$first = true;
foreach($aValues as $key => $value) {
  if(!$first) $url .= '&amp';
  else $first = false;
  $url .= 'aValues['.urlencode($key).']='.urlencode($value);
}

In case someone is using Laravel and is getting this problem. I was getting this as well and the issue was in the order in which I was inserting the ids (i.e., the foreign keys) in the pivot table.

To be concrete, find below an example for a many to many relationship:

wordtokens <-> wordtoken_wordchunk <-> wordchunks

// wordtoken_wordchunk table
Schema::create('wordtoken_wordchunk', function(Blueprint $table) {
        $table->integer('wordtoken_id')->unsigned();
        $table->integer('wordchunk_id')->unsigned();

        $table->foreign('wordtoken_id')->references('id')->on('word_tokens')->onDelete('cascade');
        $table->foreign('wordchunk_id')->references('id')->on('wordchunks')->onDelete('cascade');

        $table->primary(['wordtoken_id', 'wordchunk_id']);
    });

// wordchunks table
Schema::create('wordchunks', function (Blueprint $table) {
        $table->increments('id');
        $table->timestamps();
        $table->string('text');
    });

// wordtokens table
Schema::create('word_tokens', function (Blueprint $table) {
        $table->increments('id');
        $table->string('text');
});

Now my models look like follows:

class WordToken extends Model
{
   public function wordchunks() {
      return $this->belongsToMany('App\Wordchunk');
   }
}

class Wordchunk extends Model
{

    public function wordTokens() {
        return $this->belongsToMany('App\WordToken', 'wordtoken_wordchunk', 'wordchunk_id', 'wordtoken_id');
    }
}

I fixed the problem by exchanging the order of 'wordchunk_id' and 'wordtoken_id' in the Wordchunk model.

For code completion, this is how I persist the models:

private function persistChunks($chunks) {
    foreach ($chunks as $chunk) {
        $model = new Wordchunk();
        $model->text = implode(' ', array_map(function($token) {return $token->text;}, $chunk));
        $tokenIds = array_map(function($token) {return $token->id;}, $chunk);
        $model->save();
        $model->wordTokens()->attach($tokenIds);
    }
}

The appropriate way for doing this:

@app.route('/')
def index():
    if form.validate_on_submit():
        if 'download' in request.form:
            pass # do something
        elif 'watch' in request.form:
            pass # do something else

Put watch and download buttons into your template:

<input type="submit" name="download" value="Download">
<input type="submit" name="watch" value="Watch">

When you write data to a stream, it is not written immediately, and it is buffered. So use flush() when you need to be sure that all your data from buffer is written.

We need to be sure that all the writes are completed before we close the stream, and that is why flush() is called in file/buffered writer's close().

But if you have a requirement that all your writes be saved anytime before you close the stream, use flush().

The maximal length of the target column is shorter than the value you try to insert.

Rightclick the table in SQL manager and go to 'Design' to visualize your table structure and column definitions.

Edit:

Try to set a length on your nvarchar inserts thats the same or shorter than whats defined in your table.

You just need to add a From: header. By default there is none.

echo "Test" | mail -a "From: Someone <[email protected]>" [email protected]

You can add any custom headers using -a:

echo "Test" | mail -a "From: Someone <[email protected]>" \
                   -a "Subject: This is a test" \
                   -a "X-Custom-Header: yes" [email protected]

git log --full-history -- [file path] shows the changes of a file and works even if the file was deleted.

Example:

git log --full-history  -- myfile

If you want to see only the last commit, which deleted the file, use -1 in addition to the command above. Example:

git log --full-history -1 -- [file path]

See also my article: Which commit deleted a file.

You should check with SMTP.

That means you have to connect to that email's SMTP server.

After connecting to the SMTP server you should send these commands:

HELO somehostname.com
MAIL FROM: <[email protected]>
RCPT TO: <[email protected]>

If you get "<[email protected]> Relay access denied" that means this email is Invalid.

There is a simple PHP class. You can use it:

http://www.phpclasses.org/package/6650-PHP-Check-if-an-e-mail-is-valid-using-SMTP.html

keytool is part of jdk, it should be $JAVA_HOME/bin/keytool

Snippet to remove a element from any arraylist based on the matching condition is as follows:

List<String> nameList = new ArrayList<>();
        nameList.add("Arafath");
        nameList.add("Anjani");
        nameList.add("Rakesh");

Iterator<String> myItr = nameList.iterator();

    while (myItr.hasNext()) {
        String name = myItr.next();
        System.out.println("Next name is: " + name);
        if (name.equalsIgnoreCase("rakesh")) {
            myItr.remove();
        }
    }

Simple answer - 5 is Italian "yy" and 105 is Italian "yyyy". Therefore:

SELECT convert(datetime,'21-02-12 6:10:00 PM',5)

will work correctly, but

SELECT convert(datetime,'21-02-12 6:10:00 PM',105)

will give error.

Likewise,

SELECT convert(datetime,'21-02-2012 6:10:00 PM',5)

will give error, where as

SELECT convert(datetime,'21-02-2012 6:10:00 PM',105)

will work.

If you used managed wordpress or caching plugins, you have to CLEAR YOUR CACHE before the facebook debugger tool can fetch new info!

I've been pulling my hair out for weeks figuring out why changes I made wouldn't show up in facebook debugger for 24 hours!!!! The fix is I have to go into my wordpress dashboard, click the godaddy icon on the top, and click "flush cache." I think many managed wordpress hosters have a cache to figure out how to clear it and you'll be golden.

What you seem to be thinking is that most of the processing is handled in the node event loop. Node actually farms off the I/O work to threads. I/O operations typically take orders of magnitude longer than CPU operations so why have the CPU wait for that? Besides, the OS can handle I/O tasks very well already. In fact, because Node does not wait around it achieves much higher CPU utilisation.

By way of analogy, think of NodeJS as a waiter taking the customer orders while the I/O chefs prepare them in the kitchen. Other systems have multiple chefs, who take a customers order, prepare the meal, clear the table and only then attend to the next customer.

You can use Uber's H3,point_dist() function to compute the spherical distance between two (lat, lng) points. We can set return unit ('km', 'm', or 'rads'). The default unit is Km.

Example :

import H3

coords_1 = (52.2296756, 21.0122287)
coords_2 = (52.406374, 16.9251681)
distance = h3.point_dist(coords_1,coords_2) #278.4584889328128

Hope this will usefull!

You can use the filter function to apply more complicated regex matching.

Here's an example which would just match the first three divs:

$('div')_x000D_
  .filter(function() {_x000D_
    return this.id.match(/abc+d/);_x000D_
  })_x000D_
  .html("Matched!");

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
_x000D_
<div id="abcd">Not matched</div>_x000D_
<div id="abccd">Not matched</div>_x000D_
<div id="abcccd">Not matched</div>_x000D_
<div id="abd">Not matched</div>

you should do as:

getline(name, sizeofname, '\n');
strtok(name, " ");

This will give you the "joht" in name then to get next token,

temp = strtok(NULL, " ");

temp will get "smith" in it. then you should use string concatination to append the temp at end of name. as:

strcat(name, temp);

(you may also append space first, to obtain a space in between).

You're missing ;s. The general syntax if you put it all in one line would be:

if thing ; then ... ; else ... ; fi

The thing can be pretty much anything that returns an exit code. The then branch is taken if that thing returns 0, the else branch otherwise.

[ isn't syntax, it's the test program (check out ls /bin/[, it actually exists, man test for the docs – although can also have a built-in version with different/additional features.) which is used to test various common conditions on files and variables. (Note that [[ on the other hand is syntax and is handled by your shell, if it supports it).

For your case, you don't want to use test directly, you want to test something on the remote host. So try something like:

if ssh user@host test -e "$file" ; then ... ; else ... ; fi

To anyone with who is having this problem, its a typo error. Check your spelling of your struct delcerations and your struct

Note that sometimes you will want to use the class type name inside its own definition, for example when using Python Typing module, e.g.

class Tree:
    def __init__(self, left: Tree, right: Tree):
        self.left = left
        self.right = right

This will also result in

NameError: name 'Tree' is not defined

That's because the class has not been defined yet at this point. The workaround is using so called Forward Reference, i.e. wrapping a class name in a string, i.e.

class Tree:
    def __init__(self, left: 'Tree', right: 'Tree'):
        self.left = left
        self.right = right

The scaling on your example figure is a bit strange but you can force it by plotting the index of each x-value and then setting the ticks to the data points:

import matplotlib.pyplot as plt
x = [0.00001,0.001,0.01,0.1,0.5,1,5]
# create an index for each tick position
xi = list(range(len(x)))
y = [0.945,0.885,0.893,0.9,0.996,1.25,1.19]
plt.ylim(0.8,1.4)
# plot the index for the x-values
plt.plot(xi, y, marker='o', linestyle='--', color='r', label='Square') 
plt.xlabel('x')
plt.ylabel('y') 
plt.xticks(xi, x)
plt.title('compare')
plt.legend() 
plt.show()

this

Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);
    getSupportActionBar().setDisplayShowTitleEnabled(false);
    //toolbar.setNavigationIcon(R.drawable.ic_toolbar);
    toolbar.setTitle("");
    toolbar.setSubtitle("");
    //toolbar.setLogo(R.drawable.ic_toolbar);

var newObj = { a: 4, b: 0.5 , c: 0.35, d: 5 };
var maxValue = Math.max(...Object.values(newObj))
var minValue = Math.min(...Object.values(newObj))

You can do these in unix shell:

java -cp MyJar.jar:lib/* com.somepackage.subpackage.Main

You can do these in windows powershell:

java -cp "MyJar.jar;lib\*" com.somepackage.subpackage.Main

https://developer.mozilla.org/en/CSS/Media_queries#-moz-device-pixel-ratio

-moz-device-pixel-ratio
Gives the number of device pixels per CSS pixel.

this is almost self-explaining. the number describes the ratio of how much "real" pixels (physical pixerls of the screen) are used to display one "virtual" pixel (size set in CSS).

final indicates that the value cannot be changed once set. static allows you to set the value, and that value will be the same for ALL instances of the class which utilize it. Also, you may access the value of a public static string w/o having an instance of a class.

x=${"${arr[*]}"// /,}

This is the shortest way to do it.

Example,

arr=(1 2 3 4 5)
x=${"${arr[*]}"// /,}
echo $x  # output: 1,2,3,4,5

One solution you could use is to assign a more generalized class to any div you want the click event handler bound to.

For example:

HTML:

<body>
<div id="dog" class="selected" data-selected="false">dog</div>
<div id="cat" class="selected" data-selected="true">cat</div>
<div id="mouse" class="selected" data-selected="false">mouse</div>

<div class="dog"><img/></div>
<div class="cat"><img/></div>
<div class="mouse"><img/></div>
</body>

JS:

$( ".selected" ).each(function(index) {
    $(this).on("click", function(){
        // For the boolean value
        var boolKey = $(this).data('selected');
        // For the mammal value
        var mammalKey = $(this).attr('id'); 
    });
});

As I understand your question..

From Java List class you have to methods add(E e) and get(int position).

add(E e)

Appends the specified element to the end of this list (optional operation).

get(int index)

Returns the element at the specified position in this list.

Example:

List<String> myString = new ArrayList<String>();

// How you add your data in string list
myString.add("Test 1");
myString.add("Test 2");
myString.add("Test 3");
myString.add("Test 4");

// retrieving data from string list array in for loop
for (int i=0;i < myString.size();i++)
{
  Log.i("Value of element "+i,myString.get(i));
}

But efficient way to iterate thru loop

for (String value : myString)
{
  Log.i("Value of element ",value);
}

There are lots of answer already given for this problem. Though this issue can happens for any API version, so just see the error line and find out android api version from path and platform name and go to the android sdk manager and delete related system image from sdk manager.

I just wanted to point out that sometimes this error happens because a function has been used as a high order function (passed as an argument) and then the scope of this got lost. In such cases, I would recommend passing such function bound to this. E.g.

this.myFunction.bind(this);

I had the same problem,

Set all text/varchar collations in phpMyAdmin to utf-8 and in php files add this:

mysql_set_charset("utf8", $your_connection_name);

This solved it for me.

Simply my project wasn't in htdocs thats why it was showing me an this error make sure you put your project in HTdocs not in directory inside it

DateTime.Now.ToString("h:mm tt")
DateTime.Now.ToString("MM/dd/yyyy")

Here are some common format strings

You cannot call a non-static method from the main without instance creation, whereas you can simply call a static method. The main logic behind this is that, whenever you execute a .class file all the static data gets stored in the RAM and however, JVM(java virtual machine) would be creating context of the mentioned class which contains all the static data of the class. Therefore, it is easy to access the static data from the class without instance creation.The object contains the non-static data Context is created only once, whereas object can be created any number of times. context contains methods, variables etc. Whereas, object contains only data. thus, the an object can access both static and non-static data from the context of the class

Here's an example:

#Create a data frame
> d<- data.frame(a=1:3, b=2:4)
> d
  a b
1 1 2
2 2 3
3 3 4

#currently, there are no levels in the `a` column, since it's numeric as you point out.
> levels(d$a)
NULL

#Convert that column to a factor
> d$a <- factor(d$a)
> d
  a b
1 1 2
2 2 3
3 3 4

#Now it has levels.

You can also handle this when reading in your data. See the colClasses and stringsAsFactors parameters in e.g. readCSV().

Note that, computationally, factoring such columns won't help you much, and may actually slow down your program (albeit negligibly). Using a factor will require that all values are mapped to IDs behind the scenes, so any print of your data.frame requires a lookup on those levels -- an extra step which takes time.

Factors are great when storing strings which you don't want to store repeatedly, but would rather reference by their ID. Consider storing a more friendly name in such columns to fully benefit from factors.

As i also faced the same problem and because some people here commented that the solution wasn't working for them, here's the link to the post where a working solution has been found.

https://stackoverflow.com/a/24406721/3751590

Also see the "Update" in the best answer for using Cygwin terminal

You can use subList(int fromIndex, int toIndex) method on your integers arr, something like this:

import java.util.ArrayList;
import java.util.List;

public class Main {
    public static void main(String[] args) {
        List<Integer> arr = new ArrayList<>();
        arr.add(1);
        arr.add(2);
        arr.add(3);
        arr.add(4);
        List<Integer> partialArr = arr.subList(1, 3);

        // print the subArr
        for (Integer i: partialArr)
            System.out.println(i + " ");
    }
}

Output will be: 2 3.

Note that subList(int fromIndex, int toIndex) method performs minus 1 on the 2nd variable it receives (var2 - 1), i don't know exactly why, but that's what happens, maybe to reduce the chance of exceeding the size of the array.

Iterations

Method 1: forEach method

messages.forEach(function(message) {
   console.log(message);
}

Method 2: for..of method

for(let message of messages){
   console.log(message);
}

Note: This method might not work with objects, such as:

let obj = { a: 'foo', b: { c: 'bar', d: 'daz' }, e: 'qux' }

Method 2: for..in method

for(let key in messages){
       console.log(messages[key]);
 }

assuming the item numbers are unique, a VLOOKUP should get you the information you need.

first value would be =VLOOKUP(E1,A:B,2,FALSE), and the same type of formula to retrieve the second value would be =VLOOKUP(E1,C:D,2,FALSE). Wrap them in an IFERROR if you want to return anything other than #N/A if there is no corresponding value in the item column(s)

json.dumps() converts a dictionary to str object, not a json(dict) object! So you have to load your str into a dict to use it by using json.loads() method

See json.dumps() as a save method and json.loads() as a retrieve method.

This is the code sample which might help you understand it more:

import json

r = {'is_claimed': 'True', 'rating': 3.5}
r = json.dumps(r)
loaded_r = json.loads(r)
loaded_r['rating'] #Output 3.5
type(r) #Output str
type(loaded_r) #Output dict

No, this construct just creates a scope for naming. If you break it in parts you can see that you have an external

(...)();

That is a function invocation. Inside the parenthesis you have:

function() {}

That is an anonymous function. Everything that is declared with var inside the construct will be visible only inside the same construct and will not pollute the global namespace.

Note that you can use a variable in a slice:

l = ['a',' b',' c',' d',' e']
c_index = l.index("c")
l2 = l[:c_index]

This would put the first two entries of l in l2

As other answers pointed out, it is most likely generated by some tool.

But if I were the original author of the file, my answer would be: Consistency.

If I am not allowed to put double quotes in my attributes, why put them in the element's content ? Why do these specs always have these exceptional cases .. If I had to write the HTML spec, I would say All double quotes need to be encoded. Done.

Today it is like In attribute values we need to encode double quotes, except when the attribute value itself is defined by single quotes. In the content of elements, double quotes can be, but are not required to be, encoded. (And I am surely forgetting some cases here).

Double quotes are a keyword of the spec, encode them. Lesser/greater than are a keyword of the spec, encode them. etc..

Your schema is for its target namespace http://www.example.org/Test so it defines an element with name MyElement in that target namespace http://www.example.org/Test. Your instance document however has an element with name MyElement in no namespace. That is why the validating parser tells you it can't find a declaration for that element, you haven't provided a schema for elements in no namespace.

You either need to change the schema to not use a target namespace at all or you need to change the instance to use e.g. <MyElement xmlns="http://www.example.org/Test">A</MyElement>.

The URLSearchParams API is available in all modern browsers. For example:

const params = new URLSearchParams({_x000D_
  var1: "value",_x000D_
  var2: "value2",_x000D_
  arr: "foo",_x000D_
});_x000D_
console.log(params.toString());_x000D_
//Prints "var1=value&var2=value2&arr=foo"

Your code is working fine using bootatrap v3.3.7, but you can use word-break: break-word if it's not working at your end.

which would then look like this -

OSX users can follow by Nicolay77 or mikkom that uses the mdbtools utility. You can install it via Homebrew. Just have your homebrew installed and then go

$ homebrew install mdbtools

Then create one of the scripts described by the guys and use it. I've used mikkom's one, converted all my mdb files into sql.

$ ./to_mysql.sh myfile.mdb > myfile.sql

(which btw contains more than 1 table)

I spent a lot of time to understand all the steps. So lets describe step by step:

1. Create new identity file using ssh-keygen -t rsa. Give it an alternative like proj1.id_rsa and hit with no doubt because you don't need a passphrase.

2. Add new section in .ssh/config:

   Host proj1.github.com
       HostName github.com
       PreferredAuthentications publickey
       IdentityFile ~/.ssh/proj1.id_rsa
   

Take into account the first section and note that proj1.github.com we will back to the section later.

3. Add the identity to ssh agent ssh-add ~/.ssh/proj1.id_rsa
4. That what I messed first time - now when you want to clone a proj1 repo you do it using proj1.github.com (exactly the host from the config file). git clone [email protected].

A good tutorial.

Don't mess up with hosts

I have the following in my .bash_profile:

function mark {
    export $1=`pwd`;
}

so anytime I want to remember a directory, I can just type, e.g. mark there .

Then when I want to go back to that location, I just type cd $there

Split on tab, but then remove all blank matches.

text = "hi\tthere\t\t\tmy main man"
print [splits for splits in text.split("\t") if splits is not ""]

Outputs:

['hi', 'there', 'my main man']

brew install vim --override-system-vi

 Try this:- SELECT Case WHEN COLUMNNAME=0 THEN 'sex'
              ELSE WHEN COLUMNNAME=1 THEN 'Female' END AS YOURGRIDCOLUMNNAME FROM YOURTABLENAME

in your query for only true or false column

JsonLint is good for validating and formatting JSON.

While many of the other answers provide good examples of why you might want to catch an rethrow an exception, no one seems to have mentioned a 'finally' scenario.

An example of this is where you have a method in which you set the cursor (for example to a wait cursor), the method has several exit points (e.g. if () return;) and you want to ensure the cursor is reset at the end of the method.

To do this you can wrap all of the code in a try/catch/finally. In the finally set the cursor back to the right cursor. So that you don't bury any valid exceptions, rethrow it in the catch.

try
{
    Cursor.Current = Cursors.WaitCursor;
    // Test something
    if (testResult) return;
    // Do something else
}
catch
{
    throw;
}
finally
{
     Cursor.Current = Cursors.Default;
}

You could use $ extraction:

class(aframe$a1)
[1] "numeric"

or the double square bracket:

class(aframe[["a1"]])
[1] "numeric"

You can read about the keyword unsigned in the C++ Reference.

There are two different types in this matter, signed and un-signed. The default for integers is signed which means that they can have negative values.

On a 32-bit system an integer is 32 Bit which means it can contain a value of ~4 billion.

And when it is signed, this means you need to split it, leaving -2 billion to +2 billion.

When it is unsigned however the value cannot contain any negative numbers, so for integers this would mean 0 to +4 billion.

There is a bit more informationa bout this on Wikipedia.

You can extract numbers from a string using a regex expression:

let string = "xxfdx25y93.34xxd73";
let res = string.replace(/\D/g, "");
console.log(res); 

output: 25933473

If anyone is interested in the Infragistics solution, here it is.

1. Use

   Environment.NewLine

2. Make sure your cell is wrapped

   dataSheet.Rows[i].Cells[j].CellFormat.WrapText = ExcelDefaultableBoolean.True;

Just use a while loop:

var (i, sum) = (0, 0)
while (sum < 1000) {
  sum += i
  i += 1
}

It's not as easy as it seems to implement a control like that. Explorer works with shell items, not filesystem items (ex: the control panel, the printers folder, and so on). If you need to implement it i suggest to have a look at the Windows shell functions at http://msdn.microsoft.com/en-us/library/bb776426(VS.85).aspx.

The problem is in the import line. You are importing a module, not a class. Assuming your file is named other_file.py (unlike java, again, there is no such rule as "one class, one file"):

from other_file import findTheRange

if your file is named findTheRange too, following java's convenions, then you should write

from findTheRange import findTheRange

you can also import it just like you did with random:

import findTheRange
operator = findTheRange.findTheRange()

Some other comments:

a) @Daniel Roseman is right. You do not need classes here at all. Python encourages procedural programming (when it fits, of course)

b) You can build the list directly:

  randomList = [random.randint(0, 100) for i in range(5)]

c) You can call methods in the same way you do in java:

largestInList = operator.findLargest(randomList)
smallestInList = operator.findSmallest(randomList)

d) You can use built in function, and the huge python library:

largestInList = max(randomList)
smallestInList = min(randomList)

e) If you still want to use a class, and you don't need self, you can use @staticmethod:

class findTheRange():
    @staticmethod
    def findLargest(_list):
        #stuff...

find . -type f -name "*.xls" -printf "xls2csv %p %p.csv\n" | bash

bash 4 (recursive)

shopt -s globstar
for xls in /path/**/*.xls
do
  xls2csv "$xls" "${xls%.xls}.csv"
done

You can use this function:

function createStringArray(arr, prop) {
   var result = [];
   for (var i = 0; i < arr.length; i += 1) {
      result.push(arr[i][prop]);
   }
   return result;
}

Just pass the array of objects and the property you need. The script above will work even in old EcmaScript implementations.

I agree that the second way is preferable. The only real reason for that preference is the general preference that .NET classes not have public fields. However, if that field is readonly, I can't see how there would be any real objections other than a lack of consistency with other properties. The real difference between a readonly field and get-only property is that the readonly field provides a guarantee that its value will not change over the life of the object and a get-only property does not.

Most states are in exactly one time zone (though there are a few exceptions). Most zip codes do not cross state boundaries (though there are a few exceptions).

You could quickly come up with your own list of time zones per zip by combining those facts.

Here's a list of zip code ranges per state, and a list of states per time zone.

You can see the boundaries of zip codes and compare to the timezone map using this link, or Google Earth, to map zips to time zones for the states that are split by a time zone line.

The majority of non-US countries you are dealing with are probably in exactly one time zone (again, there are exceptions). Depending on your needs, you may want to look at where your top-N non-US visitors come from and just lookup their time zone.

Splitting a string by whitespace is very simple:

print $_, "\n" for split ' ', 'file1.gz file1.gz file3.gz';

This is a special form of split actually (as this function usually takes patterns instead of strings):

As another special case, split emulates the default behavior of the command line tool awk when the PATTERN is either omitted or a literal string composed of a single space character (such as ' ' or "\x20"). In this case, any leading whitespace in EXPR is removed before splitting occurs, and the PATTERN is instead treated as if it were /\s+/; in particular, this means that any contiguous whitespace (not just a single space character) is used as a separator.

Here's an answer for the original question (with a simple string without any whitespace):

Perhaps you want to split on .gz extension:

my $line = "file1.gzfile1.gzfile3.gz";
my @abc = split /(?<=\.gz)/, $line;
print $_, "\n" for @abc;

Here I used (?<=...) construct, which is look-behind assertion, basically making split at each point in the line preceded by .gz substring.

If you work with the fixed set of extensions, you can extend the pattern to include them all:

my $line = "file1.gzfile2.txtfile2.gzfile3.xls";
my @exts = ('txt', 'xls', 'gz');
my $patt = join '|', map { '(?<=\.' . $_ . ')' } @exts;
my @abc = split /$patt/, $line;
print $_, "\n" for @abc;

I think this is cool

SELECT value,
    PARSENAME(REPLACE(String,',','.'),2) 'Name' ,
    PARSENAME(REPLACE(String,',','.'),1) 'Sur Name'
FROM table WITH (NOLOCK)

I have struggled with the matplotlib trimming methods, so I've now just made a function to do this via a bash call to ImageMagick's mogrify command, which works well and gets all extra white space off the figure's edge. This requires that you are using UNIX/Linux, are using the bash shell, and have ImageMagick installed.

Just throw a call to this after your savefig() call.

def autocrop_img(filename):
    '''Call ImageMagick mogrify from bash to autocrop image'''
    import subprocess
    import os

    cwd, img_name = os.path.split(filename)

    bashcmd = 'mogrify -trim %s' % img_name
    process = subprocess.Popen(bashcmd.split(), stdout=subprocess.PIPE, cwd=cwd)

You can use sp page context info:

_spPageContextOnfo.userLoginName

A little late to the game but I configured mine as the following in the keybindings.json:

{
    "key": "ctrl+`",
    "command": "workbench.action.terminal.focus",
    "when": "editorTextFocus"
},
{
    "key": "ctrl+`",
    "command": "workbench.action.focusActiveEditorGroup",
    "when": "terminalFocus"
},
{
    "key": "alt+`",
    "command": "workbench.action.terminal.toggleTerminal"
}

I wanted separate keys for opening/closing terminal and switching focus back and forth between the windows.

Contents of that jQuery object are plain DOM elements, which doesn't respond to jQuery methods (e.g. .attr). You need to wrap the value by $() to turn it into a jQuery object to use it.

    console.info("cat_id: ", $(value).attr('cat_id'));

or just use the DOM method directly

    console.info("cat_id: ", value.getAttribute('cat_id'));

$(document).ready happens when all the elements are present in the DOM, but not necessarily all content.

$(document).ready(function() {
    alert("document is ready");
});

window.onload or $(window).load() happens after all the content resources (images, etc) have been loaded.

$(window).load(function() {
    alert("window is loaded");
});

Use one way flow syntax property binding:

<div [innerHTML]="comment"></div>

From angular docs: "Angular recognizes the value as unsafe and automatically sanitizes it, which removes the <script> tag but keeps safe content such as the <b> element."

You need to enable deep object dirty checking. By default angular only checks the reference of the top level variable that you watch.

App.directive('d3Visualization', function() {
    return {
        restrict: 'E',
        scope: {
            val: '='
        },
        link: function(scope, element, attrs) {
            scope.$watch('val', function(newValue, oldValue) {
                if (newValue)
                    console.log("I see a data change!");
            }, true);
        }
    }
});

see Scope. The third parameter of the $watch function enables deep dirty checking if it's set to true.

Take note that deep dirty checking is expensive. So if you just need to watch the children array instead of the whole data variable the watch the variable directly.

scope.$watch('val.children', function(newValue, oldValue) {}, true);

version 1.2.x introduced $watchCollection

Shallow watches the properties of an object and fires whenever any of the properties change (for arrays, this implies watching the array items; for object maps, this implies watching the properties)

scope.$watchCollection('val.children', function(newValue, oldValue) {});

You can use find and -exec directly into sed rather than first locating oldstr with grep. It's maybe a bit less efficient, but that might not be important. This way, the sed replacement is executed over all files listed by find, but if oldstr isn't there it obviously won't operate on it.

find /path -type f -exec sed -i 's/oldstr/newstr/g' {} \;

You need to put an actual tab character after the -t\ and to do that in a shell you hit ctrl-v and then the tab character. Most shells I've used support this mode of literal tab entry.

Beware, though, because copying and pasting from another place generally does not preserve tabs.

How about if you're copying each column in a sheet to different sheets? Example: row B of mysheet to row B of sheet1, row C of mysheet to row B of sheet 2...

What if you need any database operation in SuperGirl you would inject it again into SuperGirl.

I think the main idea is using the same object reference in different classes. So what about this:

//There is no annotation about Spring in the abstract part.
abstract class SuperMan {


    private final DatabaseService databaseService;

    public SuperMan(DatabaseService databaseService) {
     this.databaseService = databaseService;
    }

    abstract void Fly();

    protected void doSuperPowerAction(Thing thing) {

        //busy code

        databaseService.save(thing);

    }
}

@Component
public class SuperGirl extends SuperMan {

private final DatabaseService databaseService;

@Autowired
public SuperGirl (DatabaseService databaseService) {
     super(databaseService);
     this.databaseService = databaseService;
    }

@Override
public void Fly() {
    //busy code
}

public doSomethingSuperGirlDoes() {

    //busy code

    doSuperPowerAction(thing)

}

In my opinion, inject once run everywhere :)

For your interest, to do the same with double

double doubleVal = 1.745;
double doubleVal2 = 0.745;
doubleVal = Math.round(doubleVal * 100 + 0.005) / 100.0;
doubleVal2 = Math.round(doubleVal2 * 100 + 0.005) / 100.0;
System.out.println("bdTest: " + doubleVal); //1.75
System.out.println("bdTest1: " + doubleVal2);//0.75

or just

double doubleVal = 1.745;
double doubleVal2 = 0.745;
System.out.printf("bdTest: %.2f%n",  doubleVal);
System.out.printf("bdTest1: %.2f%n",  doubleVal2);

both print

bdTest: 1.75
bdTest1: 0.75

I prefer to keep code as simple as possible. ;)

As @mshutov notes, you need to add a little more to ensure that a half value always rounds up. This is because numbers like 265.335 are a little less than they appear.

int add(int a, int b)
{
  return (a+b);
}
int minus(int a, int b)
{
  return (a-b);
}

typedef int (*math_func)(int, int); //declaration of function pointer

int main()
{
  math_func addition = add;  //typedef assigns a new variable i.e. "addition" to original function "add"
  math_func substract = minus; //typedef assigns a new variable i.e. "substract" to original function "minus"

  int c = addition(11, 11);   //calling function via new variable
  printf("%d\n",c);
  c = substract(11, 5);   //calling function via new variable
  printf("%d",c);
  return 0;
}

Output of this is :

22

6

Note that, same math_func definer has been used for the declaring both the function.

Same approach of typedef may be used for extern struct.(using sturuct in other file.)

What is important is that the apache user and group should have minimum read access and in some cases execute access. For the rest you can give 0 access.

This is the most safe setting.

Override windowClosing Method.

public void windowClosing(WindowEvent e)

It is invoked when a window is in the process of being closed. The close operation can be overridden at this point.

I just wrote a script that lets you achieve this. It gives you two global functions: hasEvent(Node elm, String event) and getEvents(Node elm) which you can utilize. Be aware that it modifies the EventTarget prototype method add/RemoveEventListener, and does not work for events added through HTML markup or javascript syntax of elm.on_event = ...

More info at GitHub

Live Demo

Script:

var hasEvent,getEvents;!function(){function b(a,b,c){c?a.dataset.events+=","+b:a.dataset.events=a.dataset.events.replace(new RegExp(b),"")}function c(a,c){var d=EventTarget.prototype[a+"EventListener"];return function(a,e,f,g,h){this.dataset.events||(this.dataset.events="");var i=hasEvent(this,a);return c&&i||!c&&!i?(h&&h(),!1):(d.call(this,a,e,f),b(this,a,c),g&&g(),!0)}}hasEvent=function(a,b){var c=a.dataset.events;return c?new RegExp(b).test(c):!1},getEvents=function(a){return a.dataset.events.replace(/(^,+)|(,+$)/g,"").split(",").filter(function(a){return""!==a})},EventTarget.prototype.addEventListener=c("add",!0),EventTarget.prototype.removeEventListener=c("remove",!1)}();

As defer attribute works only with scripts tag with src. Found a way to mimic defer for inline scripts. Use DOMContentLoaded event.

<script defer src="external-script.js"></script>
<script>
document.addEventListener("DOMContentLoaded", function(event) {
    // Your inline scripts which uses methods from external-scripts.
});
</script>

This is because, DOMContentLoaded event fires after defer attributed scripts are completely loaded.

I did everything from visiting http://www.google.com/accounts/DisplayUnlockCaptcha to setting up 2-fa and creating an application password. The only thing that worked was logging into http://mail.google.com and sending an email from the server itself.

Quick Command for Finding Date/Time Metadata in Many Video Files

The following command has served me well in finding date/time metadata on various AVI/MP4 videos:

ffmpeg -i /path/to/video.mp4 -dump

Note: as mentioned in other answers, there is no guarantee that such information is available in all video files or available in a specific format.

Abbreviated Sample Output for Some AVI File

I was trying to Navigate from Page 1 to 2, and I had to pass some data as well.

In my router.js, I added params name and age :

.state('page2', {
          url: '/vehicle/:source',
          params: {name: null, age: null},
.................

In Page1, onClick of next button :

$state.go("page2", {name: 'Ron', age: '20'});

In Page2, I could access those params :

$stateParams.name
$stateParams.age

How about just doing some linq queries against your dictionary, and then binding your graph to the results of those?...

var under = colStates.Where(c => (decimal)c.Value / (decimal)totalCount < .05M);
var over = colStates.Where(c => (decimal)c.Value / (decimal)totalCount >= .05M);
var newColStates = over.Union(new Dictionary<string, int>() { { "Other", under.Sum(c => c.Value) } });

foreach (var item in newColStates)
{
    Console.WriteLine("{0}:{1}", item.Key, item.Value);
}

Look at this online backend.

Parse.com

They offer push notifications, social integration, data storage, and the ability to add rich custom logic to your app’s backend with Cloud Code.

You can try this:

string[] arr = ((IEnumerable)obj).Cast<object>()
                                 .Select(x => x.ToString())
                                 .ToArray();

Once every array implements IEnumerable interface

Replace 123 with number of commits your branch has diverged from origin.

git reset HEAD~123 && git reset && git checkout . && git clean -fd && git pull

I found out about this one (Unzip package on NuGet) today, since I ran into a hard bug in DotNetZip, and I realized there hasn't been really that much work done on DotNetZip for the last two years.

The Unzip package is lean, and it did the job for me - it didn't have the bug that DotNetZip had. Also, it was a reasonably small file, relying upon the Microsoft BCL for the actual decompression. I could easily make adjustments which I needed (to be able to keep track of the progress while decompressing). I recommend it.

Until the end of 2014, a common source of this error was omitting the mandatory sensor parameter from the request, as below. However since then this is no longer required:

The sensor Parameter

The Google Maps API previously required that you include the sensor parameter to indicate whether your application used a sensor to determine the user's location. This parameter is no longer required.

Did you specify the sensor parameter on the request?

"REQUEST_DENIED" indicates that your request was denied, generally because of lack of a sensor parameter.

sensor (required) — Indicates whether or not the geocoding request comes from a device with a location sensor. This value must be either true or false

Works fine too:

/* small screen portrait */

@media (max-width: 321px) {

  .pull-right { 
    float: none!important; 
  }

}


/* small screen lanscape */

@media (max-width: 480px) {

  .pull-right {
    float: none!important; 
  }

}

In my case I found that I have an aggressive plugin for Vim, just restarted it.

To avoid warnings like:

npm WARN [email protected] No repository field.

You must define repository in your project package.json. In the case when you are developing with no publishing to the repository you can set "private": true in package.json

Example:

{
  "name": "test.loc",
  "version": "1.0.0",
  "private": true,
  ...
  "license": "ISC"
}

NPM documentation about this: https://docs.npmjs.com/files/package.json

I had the same problem with Pool() in Python 3.6.3.

Error received: TypeError: can't pickle _thread.RLock objects

Let's say we want to add some number num_to_add to each element of some list num_list in parallel. The code is schematically like this:

class DataGenerator:
    def __init__(self, num_list, num_to_add)
        self.num_list = num_list # e.g. [4,2,5,7]
        self.num_to_add = num_to_add # e.g. 1 

        self.run()

    def run(self):
        new_num_list = Manager().list()

        pool = Pool(processes=50)
        results = [pool.apply_async(run_parallel, (num, new_num_list)) 
                      for num in num_list]
        roots = [r.get() for r in results]
        pool.close()
        pool.terminate()
        pool.join()

    def run_parallel(self, num, shared_new_num_list):
        new_num = num + self.num_to_add # uses class parameter
        shared_new_num_list.append(new_num)

The problem here is that self in function run_parallel() can't be pickled as it is a class instance. Moving this parallelized function run_parallel() out of the class helped. But it's not the best solution as this function probably needs to use class parameters like self.num_to_add and then you have to pass it as an argument.

Solution:

def run_parallel(num, shared_new_num_list, to_add): # to_add is passed as an argument
    new_num = num + to_add
    shared_new_num_list.append(new_num)

class DataGenerator:
    def __init__(self, num_list, num_to_add)
        self.num_list = num_list # e.g. [4,2,5,7]
        self.num_to_add = num_to_add # e.g. 1

        self.run()

    def run(self):
        new_num_list = Manager().list()

        pool = Pool(processes=50)
        results = [pool.apply_async(run_parallel, (num, new_num_list, self.num_to_add)) # num_to_add is passed as an argument
                      for num in num_list]
        roots = [r.get() for r in results]
        pool.close()
        pool.terminate()
        pool.join()

Other suggestions above didn't help me.

Yes, they're both JavaScript, you can use whichever functions are appropriate for the situation.

In this case you can just put the code in a document.ready handler, like this:

$(function() {
  var canvas = document.getElementById("canvas");
  if (canvas.getContext) {
    var ctx = canvas.getContext("2d");

    ctx.fillStyle = "rgb(200,0,0)";
    ctx.fillRect (10, 10, 55, 50);

    ctx.fillStyle = "rgba(0, 0, 200, 0.5)";
    ctx.fillRect (30, 30, 55, 50);
  }
});

    String data = "This world is mine";
    System.out.print(data.split("\\s+").length);

You need to change project settings. Right click your project, go to properites. In Application tab change output type to class library instead of Windows application.

Service

• Invoke by startService()
• Triggered from any Thread
• Runs on Main Thread
• May block main (UI) thread. Always use thread within service for long task
• Once task has done, it is our responsibility to stop service by calling stopSelf() or stopService()

IntentService

• It performs long task usually no communication with main thread if communication is needed then it is done by Handler or BroadcastReceiver
• Invoke via Intent
• Triggered from Main Thread
• Runs on the separate thread
• Can't run the task in parallel and multiple intents are Queued on the same worker thread.

Syntax

print_r(variable, return);

variable Required. Specifies the variable to return information about

return Optional. When set to true, this function will return the information (not print it). Default is false

Example

error_log( print_r(<array Variable>, TRUE) );

If you installed mongodb with homebrew, there's an easier way:

List mongo job with launchctl:

launchctl list | grep mongo

Stop mongo job:

launchctl stop <job label>

(For me this is launchctl stop homebrew.mxcl.mongodb)

Start mongo job:

launchctl start <job label>

I liked lavinio's answer, but shifting bits adds some complexity. Often there's a choice of moving bits while respecting the sign bit or while not respecting the sign bit. This is the choice between treating the numbers as signed (-8 to 7 for a nibble, -128 to 127 for bytes) or full-range unsigned numbers (0 to 15 for nibbles, 0 to 255 for bytes).

Some good answers here but just adding an approach that won't be affected by borders and padding:

<style type="text/css">
html, body{width: 100%; height: 100%; padding: 0; margin: 0}
div{position: absolute; padding: 1em; border: 1px solid #000}
#nw{background: #f09; top: 0; left: 0; right: 50%; bottom: 50%}
#ne{background: #f90; top: 0; left: 50%; right: 0; bottom: 50%}
#sw{background: #009; top: 50%; left: 0; right: 50%; bottom: 0}
#se{background: #090; top: 50%; left: 50%; right: 0; bottom: 0}
</style>

<div id="nw">test</div>
<div id="ne">test</div>
<div id="sw">test</div>
<div id="se">test</div>

Let me expand a bit on a VonC's very comprehensive answer:

First, if I remember it correctly, the fact that Git by default doesn't create merge commits in the fast-forward case has come from considering single-branch "equal repositories", where mutual pull is used to sync those two repositories (a workflow you can find as first example in most user's documentation, including "The Git User's Manual" and "Version Control by Example"). In this case you don't use pull to merge fully realized branch, you use it to keep up with other work. You don't want to have ephemeral and unimportant fact when you happen to do a sync saved and stored in repository, saved for the future.

Note that usefulness of feature branches and of having multiple branches in single repository came only later, with more widespread usage of VCS with good merging support, and with trying various merge-based workflows. That is why for example Mercurial originally supported only one branch per repository (plus anonymous tips for tracking remote branches), as seen in older revisions of "Mercurial: The Definitive Guide".

Second, when following best practices of using feature branches, namely that feature branches should all start from stable version (usually from last release), to be able to cherry-pick and select which features to include by selecting which feature branches to merge, you are usually not in fast-forward situation... which makes this issue moot. You need to worry about creating a true merge and not fast-forward when merging a very first branch (assuming that you don't put single-commit changes directly on 'master'); all other later merges are of course in non fast-forward situation.

HTH

Use count()

if (count($my_array) > 1) {
// do
}

this page explains it pretty well http://phparraylength.com/

There is a len method:

>>> a = 'a string of some length'
>>> a.__len__()
23
>>> a.__len__
<method-wrapper '__len__' of str object at 0x02005650>

The => operator is used to assign key-value pairs in an associative array. For example:

$fruits = array(
  'Apple'  => 'Red',
  'Banana' => 'Yellow'
);

It's meaning is similar in the foreach statement:

foreach ($fruits as $fruit => $color)
  echo "$fruit is $color in color.";

If you want to do it (what I think you are trying right now) then replace this line

<input type="submit" <a href="#" onclick="history.back();">"Back"</a>

with this

<button type="button" onclick="history.back();">Back</button>

If you don't want to rely on JavaScript then you could get the HTTP_REFERER variable an then provide it in a link like this:

<a href="<?php echo $_SERVER['HTTP_REFERER'] ?>">Back</a>

Remove the multiple="multiple" attribute and add SIZE=6 with the number of elements you want

ActStatus.pipe.ts First this is my pipe

import {Pipe,PipeTransform} from "@angular/core";

@Pipe({
  name:'actStatusPipe'
})
export class ActStatusPipe implements PipeTransform{
  transform(status:any):any{
    switch (status) {
      case 1:
        return "UN_PUBLISH";
      case 2:
        return "PUBLISH";
      default:
        return status
    }
  }
}

main-pipe.module.ts in pipe module, i need to declare my pipe/s and export it.

import { NgModule } from '@angular/core';
import {CommonModule} from "@angular/common";

import {ActStatusPipe} from "./ActStatusPipe.pipe"; // <---

@NgModule({
  declarations:[ActStatusPipe], // <---
  imports:[CommonModule],
  exports:[ActStatusPipe] // <---
})

export class MainPipe{}

app.module.ts user this pipe module in any module.

@NgModule({
  declarations: [...],
  imports: [..., MainPipe], // <---
  providers: [...],
  bootstrap: [AppComponent]
})

you can directly user pipe in this module. but if you feel that your pipe is used with in more than one component i suggest you to follow my approach.

1. create pipe .
2. create separate module and declare and export one or more pipe.
3. user that pipe module.

How to use pipe totally depends on your project complexity and requirement. you might have just one pipe which used only once in the whole project. in that case you can directly use it without creating a pipe/s module (module approach).

"Equivalent" is the word here

While...

$('#selectlist').val();

...is equivalent to...

document.getElementById("selectlist").value

...it's worth noting that...

$('#selectlist')

...although 'equivalent' is not the same as...

document.getElementById("selectlist")

...as the former returns a jQuery object, not a DOM object.

To get the DOM object(s) from the jQuery one, use the following:

$('#selectlist').get(); //get all DOM objects in the jQuery collection
$('#selectlist').get(0); //get the DOM object in the jQuery collection at index 0
$('#selectlist')[0]; //get the DOM objects in the jQuery collection at index 0

    public Form1()
    {
        InitializeComponent();

        string myHost = System.Net.Dns.GetHostName();
        string myIP = null;

        for (int i = 0; i <= System.Net.Dns.GetHostEntry(myHost).AddressList.Length - 1; i++)
        {
            if (System.Net.Dns.GetHostEntry(myHost).AddressList[i].IsIPv6LinkLocal == false)
            {
                myIP = System.Net.Dns.GetHostEntry(myHost).AddressList[i].ToString();
            }
        }
    }

Declare myIP and myHost in public Variable and use in any function of the form.

This should display 'Tue':

new SimpleDateFormat("EEE").format(new Date());

This should display 'Tuesday':

new SimpleDateFormat("EEEE").format(new Date());

This should display 'T':

new SimpleDateFormat("EEEEE").format(new Date());

So your specific example would be:

new SimpleDateFormat("yyyy-MM-EEE").format(new Date());

I had a similar problem and I tried multiple solution. I solved it implementing 2 considerations.

1. Using dangerouslySetInnerHtml to embed the <video> code. For example:

<div dangerouslySetInnerHTML={{ __html: `
    <video class="video-js" playsinline autoplay loop muted>
        <source src="../video_path.mp4" type="video/mp4"/>
    </video>`}}
/>

2. Resizing the video weight. I noticed my iPhone does not autoplay videos over 3 megabytes. So I used an online compressor tool (https://www.mp4compress.com/) to go from 4mb to less than 500kb

Also, thanks to @boltcoder for his guide: Autoplay muted HTML5 video using React on mobile (Safari / iOS 10+)

In WebStart and the new 6u10 PlugIn you can use the FileOpenService, even without security permissions. For obvious reasons, you only get the file contents, not the file path.

To resolve this error:

ORA-01653 unable to extend table by 1024 in tablespace your-tablespace-name

Just run this PL/SQL command for extended tablespace size automatically on-demand:

alter database datafile '<your-tablespace-name>.dbf' autoextend on maxsize unlimited;

I get this error in import big dump file, just run this command without stopping import routine or restarting the database.

Note: each data file has a limit of 32GB of size if you need more than 32GB you should add a new data file to your existing tablespace.

More info: alter_autoextend_on

Best solution can be:

Add a string parameter in the existing job

Then in the Source Code Management section update Branches to build to use the string parameter you defined

If you see a checkbox labeled Lightweight checkout, make sure it is unchecked.

The configuration indicated in the images will tell the jenkins job to use master as the default branch, and for manual builds it will ask you to enter branch details (FYI: by default it's set to master)

I've never had this problem, but I create a ~/.crontab file and edit that (which allows me to back it up, Time Machine or otherwise), then run

For those of you who work on a remote computer with ssh, and maintain a Jupyter notebook server inside a tmux session, then after you exit the Jupyter notebook, you also have to close the pane that was used to maintain your Jupyter notebook server. Otherwise, it could cause issues when you try to log out from the ssh.

I think ./gradlew tasks is same with Android studio sync. Why? I will explain it.

I meet a problem when I test jacoco coverage report. When I run ./gradlew clean :Test:testDebugUnitTest in command line directly , error appear.

Error opening zip file or JAR manifest missing : build/tmp/expandedArchives/org.jacoco.agent-0.8.2.jar_5bdiis3s7lm1rcnv0gawjjfxc/jacocoagent.jar

However, if I click android studio sync firstly , it runs OK. Because the build/../jacocoagent.jar appear naturally. I dont know why, maybe there is bug in jacoco plugin. Unit I find running .gradlew tasks makes the jar appear as well. So I can get the same result in gralde script.

Besides, gradle --recompile-scripts does not work for the problem.

Have a look at here this link and their roadmap. They have RO|C on the way, and that can connect to their web services, which probably includes SOAP (I use the VCL version which definitely includes it).

you should man date first

date +%Y-%m-%d
date +%Y-%m-%d -d yesterday

Check if the cross product of b-a and c-a is0: that means all the points are collinear. If they are, check if c's coordinates are between a's and b's. Use either the x or the y coordinates, as long as a and b are separate on that axis (or they're the same on both).

def is_on(a, b, c):
    "Return true iff point c intersects the line segment from a to b."
    # (or the degenerate case that all 3 points are coincident)
    return (collinear(a, b, c)
            and (within(a.x, c.x, b.x) if a.x != b.x else 
                 within(a.y, c.y, b.y)))

def collinear(a, b, c):
    "Return true iff a, b, and c all lie on the same line."
    return (b.x - a.x) * (c.y - a.y) == (c.x - a.x) * (b.y - a.y)

def within(p, q, r):
    "Return true iff q is between p and r (inclusive)."
    return p <= q <= r or r <= q <= p

This answer used to be a mess of three updates. The worthwhile info from them: Brian Hayes's chapter in Beautiful Code covers the design space for a collinearity-test function -- useful background. Vincent's answer helped to improve this one. And it was Hayes who suggested testing only one of the x or the y coordinates; originally the code had and in place of if a.x != b.x else.

I've traditionally followed the advice found in VVS's answer. However, in an effort to keep this answer up-to-date with the latest options, I think all my future projects will use the "NetOffice" library.

NetOffice is a complete replacement for the Office PIAs and is completely version-agnostic. It's a collection of Managed COM wrappers that can handle the cleanup that often causes such headaches when working with Microsoft Office in .NET.

Some key features are:

• Mostly version-independent (and version-dependant features are documented)
• No dependencies
• No PIA
• No registration
• No VSTO

I am in no way affiliated with the project; I just genuinely appreciate the stark reduction in headaches.

I had a similar problem when dumping a Django mysql database with a single table. I was able to fix the problem by dumping the database to a text file, moving the table in question to the end of the file using emacs and importing the modified sql dump file into the new instance.

Repository selection screen cannot be shown on your system (OS X), since OS X no longer includes X11. R tries to show you the prompt through X11. Install X11 from http://xquartz.macosforge.org/landing/. Then run the install command. The repo selection prompt will be shown.

You can right click the procedure, choose properties and see which permissions are granted to your login ID. You can then manually check off the "Execute" and alter permission for the proc.

Or to script this it would be:

GRANT EXECUTE ON OBJECT::dbo.[PROCNAME]
    TO [ServerInstance\user];

GRANT ALTER ON OBJECT::dbo.[PROCNAME]
    TO [ServerInstance\user];

You can also do like this,

 <form method='POST'>
    {{form1.as_p}}
    <button type="submit" name="btnform1">Save Changes</button>
    </form>
    <form method='POST'>
    {{form2.as_p}}
    <button type="submit" name="btnform2">Save Changes</button>
    </form>

CODE

if request.method=='POST' and 'btnform1' in request.POST:
    do something...
if request.method=='POST' and 'btnform2' in request.POST:
    do something...

Tested this code

java.text.DateFormat formatter = new java.text.SimpleDateFormat("MM-dd-yyyy");
java.util.Date newDate = new java.util.Date();
System.out.println(formatter.format(newDate ));

xml:space="preserve" has to work for all compliant XML parsers.

However, note that in HTML the line break is just whitespace and NOT a line break (this is represented with the <br /> (X)HTML tag, maybe this is the problem which you are facing.

You can also add 
 and/or 
 to insert CR/LF characters.

git revert HEAD -m 1

In the above code line. "Last argument represents"

• 1 - reverts one commits.

• 2 - reverts last two commits.

• n - reverts last n commits.

You need to push after this command to take the effect on remote. You have other options like specifying the range of commits to revert. This is one of the option.

Later use git commit -am "COMMIT_MESSAGE" then git push or git push -f

You can use android's inbuilt Patterns:

public boolean validCellPhone(String number)
{
    return android.util.Patterns.PHONE.matcher(number).matches();
}

This pattern is intended for searching for things that look like they might be phone numbers in arbitrary text, not for validating whether something is in fact a phone number. It will miss many things that are legitimate phone numbers.

The pattern matches the following:

• Optionally, a + sign followed immediately by one or more digits. Spaces, dots, or dashes may follow.
• Optionally, sets of digits in parentheses, separated by spaces, dots, or dashes.
• A string starting and ending with a digit, containing digits, spaces, dots, and/or dashes.

Try this:

insert into MyTable(field1, field2, id_backup)
    select field1, field2, uniqueId from MyTable where uniqueId = @Id;

Any fields not specified should receive their default value (which is usually NULL when not defined).

I had the same issue because my file was called email.py. I renamed the file and the issue disappeared.

I saw another question on just this topic recently (streaming pdf into iframe using dataurl only works in chrome).

I've constructed pdfs in the ast and streamed them to the browser. I was creating them first with fdf, then with a pdf class I wrote myself - in each case the pdf was created from data retrieved from a COM object based on a couple of of GET params passed in via the url.

From looking at your data sent recieved in the ajax call, it looks like you're nearly there. I haven't played with the code for a couple of years now and didn't document it as well as I'd have cared to, but - I think all you need to do is set the target of an iframe to be the url you get the pdf from. Though this may not work - the file that oututs the pdf may also have to outut a html response header first.

In a nutshell, this is the output code I used:

//We send to a browser
header('Content-Type: application/pdf');
if(headers_sent())
    $this->Error('Some data has already been output, can\'t send PDF file');
header('Content-Length: '.strlen($this->buffer));
header('Content-Disposition: inline; filename="'.$name.'"');
header('Cache-Control: private, max-age=0, must-revalidate');
header('Pragma: public');
ini_set('zlib.output_compression','0');
echo $this->buffer;

So, without seeing the full response text fro the ajax call I can't really be certain what it is, though I'm inclined to think that the code that outputs the pdf you're requesting may only be doig the equivalent of the last line in the above code. If it's code you have control over, I'd try setting the headers - then this way the browser can just deal with the response text - you don't have to bother doing a thing to it.

I simply constructed a url for the pdf I wanted (a timetable) then created a string that represented the html for an iframe of the desired sie, id etc that used the constructed url as it's src. As soon as I set the inner html of a div to the constructed html string, the browser asked for the pdf and then displayed it when it was received.

function  showPdfTt(studentId)
{
    var url, tgt;
    title = byId("popupTitle");
    title.innerHTML = "Timetable for " + studentId;
    tgt = byId("popupContent");
    url = "pdftimetable.php?";
    url += "id="+studentId;
    url += "&type=Student";
    tgt.innerHTML = "<iframe onload=\"centerElem(byId('box'))\" src='"+url+"' width=\"700px\" height=\"500px\"></iframe>";
}

EDIT: forgot to mention - you can send binary pdf's in this manner. The streams they contain don't need to be ascii85 or hex encoded. I used flate on all the streams in the pdf and it worked fine.

HomeBrew versions has been removed and formulaes have been emptied. Therefore, my advice is to install it manually following the following steps.

For the time being you will need to build and install the Protocol Buffers toolset manually.

1. Download source code: https://github.com/google/protobuf/releases/download/v2.4.1/protobuf-2.4.1.tar.gz

2. tar xvfz protobuf-2.4.1.tar.gz

3. cd protobuf-2.4.1

4. Run ./configure

5. Edit src/google/protobuf/message.cc, add #include at the top of the file

6. Run make command from root of the folder, i.e. protobuf-2.4.1/

7. Run sudo make install

8. Run /usr/local/bin/protoc --version to check the version of protobuf compiler version The terminal output should be:

   Version: libprotoc 2.4.1

Download version tar.gz for windows and just extract files to the folder by your needs. On the left pane, you can select which version of openjdk to download

Tutorial: unzip as expected. You need to set system variable PATH to include your directory with openjdk so you can type java -version in console.

JDK vs OpenJDK

Turn on the server log:

log_statement = all

This will log every call to the database server.

I would not use log_statement = all on a production server. Produces huge log files.
The manual about logging-parameters:

log_statement (enum)

Controls which SQL statements are logged. Valid values are none (off), ddl, mod, and all (all statements). [...]

Resetting the log_statement parameter requires a server reload (SIGHUP). A restart is not necessary. Read the manual on how to set parameters.

Don't confuse the server log with pgAdmin's log. Two different things!

You can also look at the server log files in pgAdmin, if you have access to the files (may not be the case with a remote server) and set it up correctly. In pgadmin III, have a look at: Tools -> Server status. That option was removed in pgadmin4.

I prefer to read the server log files with vim (or any editor / reader of your choice).

Easiest and simplest way would be:

isInFile=$(cat file.txt | grep -c "string")


if [ $isInFile -eq 0 ]; then
   #string not contained in file
else
   #string is in file at least once
fi

grep -c will return the count of how many times the string occurs in the file.

$image="img_name.jpg";
$pdf =new FPDF();
$pdf-> AddPage();
$pdf-> SetFont("Arial","B",10);
$pdf-> Image('profileimage/'.$image,100,15,35,35);

Try this:

var control = false;
$(document).on('keyup keydown', function(e) {
  control = e.ctrlKey;
});

$('div#1').on('click', function() {
  if (control) {
    // control-click
  } else {
    // single-click
  }
});

And the right-click triggers a contextmenu event, so:

$('div#1').on('contextmenu', function() {
  // right-click handler
})

Here is one implementation:

class Enum(set):
    def __getattr__(self, name):
        if name in self:
            return name
        raise AttributeError

Here is its usage:

Animals = Enum(["DOG", "CAT", "HORSE"])

print(Animals.DOG)

When you need an outer join the second syntax is not always required:

Oracle:

SELECT a.foo, b.foo
  FROM a, b
 WHERE a.x = b.x(+)

MSSQLServer (although it's been deprecated in 2000 version)/Sybase:

SELECT a.foo, b.foo
  FROM a, b
 WHERE a.x *= b.x

But returning to your question. I don't know the answer, but it is probably related to the fact that a join is more natural (syntactically, at least) than adding an expression to a where clause when you are doing exactly that: joining.

People who are using Bootstrap 4 can achieve with this method. classes mentioned in HTML code are from Bootstrap 4.

h1 {
    position: relative;
    flex-grow: 1;
    margin: 0;
}

h1:before {
   content: "";
   display: block;
   border-top: solid 2px blue;
   width: 100%;
   height: 1px;
   position: absolute;
   top: 50%;
   z-index: 1;
 }
 h1 span {
   background: #fff;
   left: 12%;
   padding: 0 15px;
   position: relative;
   z-index: 5;
 }

And write your HTML like this

<div class="d-flex flex-row align-items-center">
  <h1><span> Title </span> </h1>
</div>

I would try Scott's CLR function first but add a WHERE clause to reduce the number of records updated.

UPDATE table SET phoneNumber = dbo.StripNonNumeric(phoneNumber) 
WHERE phonenumber like '%[^0-9]%'

If you know that the great majority of your records have non-numeric characters it might not help though.

The canonical way to do this with Rails 3:

Foo.includes(:bar).where("bars.id IS NOT NULL")

ActiveRecord 4.0 and above adds where.not so you can do this:

Foo.includes(:bar).where.not('bars.id' => nil)
Foo.includes(:bar).where.not(bars: { id: nil })

When working with scopes between tables, I prefer to leverage merge so that I can use existing scopes more easily.

Foo.includes(:bar).merge(Bar.where.not(id: nil))

Also, since includes does not always choose a join strategy, you should use references here as well, otherwise you may end up with invalid SQL.

Foo.includes(:bar)
   .references(:bar)
   .merge(Bar.where.not(id: nil))

You can check if the value is undefined or null by simply using typeof:

if(typeof value == 'undefined'){

That package in fact is available through packagist. You don't need a custom repository definition in this case. Just make sure you add a require (which is always needed) with a matching version constraint.

In general, if a package is available on packagist, do not add a VCS repo. It will just slow things down.

For packages that are not available via packagist, use a VCS (or git) repository, as shown in your question. When you do, make sure that:

• The "repositories" field is specified in the root composer.json (it's a root-only field, repository definitions from required packages are ignored)
• The repositories definition points to a valid VCS repo
• If the type is "git" instead of "vcs" (as in your question), make sure it is in fact a git repo
• You have a require for the package in question
• The constraint in the require matches the versions provided by the VCS repo. You can use composer show <packagename> to find the available versions. In this case ~2.3 would be a good option.
• The name in the require matches the name in the remote composer.json. In this case, it is gedmo/doctrine-extensions.

Here is a sample composer.json that installs the same package via a VCS repo:

{
    "repositories": [
        {
            "url": "https://github.com/l3pp4rd/DoctrineExtensions.git",
            "type": "git"
        }
    ],
    "require": {
        "gedmo/doctrine-extensions": "~2.3"
    }
}

The VCS repo docs explain all of this quite well.

If there is a git (or other VCS) repository with a composer.json available, do not use a "package" repo. Package repos require you to provide all of the metadata in the definition and will completely ignore any composer.json present in the provided dist and source. They also have additional limitations, such as not allowing for proper updates in most cases.

Avoid package repos (see also the docs).

document.getElementById("printf").contentWindow.print();

Same origin policy applies.

You could still use that event. Just check that the sender argument is the control you actually care about and if so, run the event code.

Is there a reason you're not using CSS selectors to style the first and last elements instead of trying to attach a custom class to them? Instead of styling based on alpha or omega, use first-child and last-child.

Angular CLI version 9 (used to create Angular 9 projects) now picks up style from schematics instead of styleext. Use the command like this:
ng config schematics.@schematics/angular:component.style scss
and the resulting angular.json shall look like this

"schematics": {
   "@schematics/angular:component": {
      "style": "scss"
    }
  }

Other possible solutions & explanations:

To create a new project with angular CLI with sass support, try this:

ng new My_New_Project --style=scss 

You can also use --style=sass & if you don't know the difference, read this short & easy article and if you still don't know, just go with scss & keep learning.

If you have an angular 5 project, use this command to update the config for your project.

ng set defaults.styleExt scss

For Latest Versions

For Angular 6 to set new style on existing project with CLI:

ng config schematics.@schematics/angular:component.styleext scss

Or Directly into angular.json:

"schematics": {
      "@schematics/angular:component": {
      "styleext": "scss"
    }
}

You could convert the dataframe to be a single column with stack (this changes the shape from 5x3 to 15x1) and then take the standard deviation:

df.stack().std()         # pandas default degrees of freedom is one

Alternatively, you can use values to convert from a pandas dataframe to a numpy array before taking the standard deviation:

df.values.std(ddof=1)    # numpy default degrees of freedom is zero

Unlike pandas, numpy will give the standard deviation of the entire array by default, so there is no need to reshape before taking the standard deviation.

A couple of additional notes:

• The numpy approach here is a bit faster than the pandas one, which is generally true when you have the option to accomplish the same thing with either numpy or pandas. The speed difference will depend on the size of your data, but numpy was roughly 10x faster when I tested a few different sized dataframes on my laptop (numpy version 1.15.4 and pandas version 0.23.4).

• The numpy and pandas approaches here will not give exactly the same answers, but will be extremely close (identical at several digits of precision). The discrepancy is due to slight differences in implementation behind the scenes that affect how the floating point values get rounded.

template <typename T>
struct array {
  size_t x;
  T *ary;
};

First method

This method seems to work when the content doesn't include ?.

Install xsel or similar and assign a global shortcut key for this command in your WM or DE:

xsel -o | sed -r 's/^ ?[[:digit:]]+($| +)//g' | perl -pe 's/\n/?/g' | sed -r 's/??/\n\n/g; s/ ?? {1,}/ /g; s/?/\n/g' | xsel -b

Put this in your ~/.Xresources:

*selectToClipboard: false

Issue this in your xterm once to activate the above option:

xrdb -load ~/.Xresources

Now select the line(s) including the line numbers by pressing Shift while dragging the mouse. After the selection click your key combo; the line(s) are coppied and ready to be pasted anywhere you like.

Second method

Doesn't have the shortcoming of the first method.

Install xdotool and xsel or similar.

Put these two lines

Ctrl <Btn3Down>: select-start(PRIMARY, CLIPBOARD)
Ctrl <Btn3Up>: select-end(CLIPBOARD, PRIMARY)

in your ~/.Xresources like so:

*VT100*translations: #override \n\
    Alt <Key> 0xf6: exec-formatted("xdg-open '%t'", PRIMARY, CUT_BUFFER0) \n\                           
    Ctrl <Key>0x2bb: copy-selection(CLIPBOARD) \n\                              
    Alt <Key>0x2bb: insert-selection(CLIPBOARD) \n\                             
    Ctrl <Key> +:       larger-vt-font() \n\                                    
    Ctrl <Key> -:       smaller-vt-font() \n\
    Ctrl <Btn3Down>: select-start(PRIMARY, CLIPBOARD) \n\
    Ctrl <Btn3Up>: select-end(CLIPBOARD, PRIMARY) 

Issue this in your xterm once to activate the above option:

xrdb -load ~/.Xresources

Create this scrip in your path:

#!/bin/bash                                                                  

filepid=$(xdotool getwindowpid $(xdotool getactivewindow))                   
file=$(ps -p "$filepid" o cmd | grep -o --color=never "/.*")                   

firstline=$(xsel -b)                                                         
lastline=$(xsel)                                                             

sed -n ""$firstline","$lastline"p" "$file" | xsel -b

Assign a global shortcut key to call this script in your WM or DE.

Now when you want to copy a line (paragraph), select only the line number of that line (paragraph) by right mouse button while pressing Shift+Ctrl. After the selection click your custom global key combo you've created before. The line (paragraph) is coppied and ready to be pasted anywhere you like.

If you want to copy multiple lines, do the above for the first line and then for the last line of the range, instead of Shift+Ctrl+Btn3 (right mouse button), just select the number by left mouse button while pressing only Shift. After this, again call the script by your custom global shortcut. The range of lines are coppied and ready to pasted anywhere you like.

 File f1 = new File("..\\..\\..\\config.properties");  

this path trying to access file is in Project directory then just access file like this.

File f=new File("filename.txt");

if your file is in OtherSources/Resources

this.getClass().getClassLoader().getResource("relative path");//-> relative path from resources folder

Recent bash versions allow fall-through by using ;& in stead of ;;: they also allow resuming the case checks by using ;;& there.

for n in 4 14 24 34
do
  echo -n "$n = "
  case "$n" in
   3? )
     echo -n thirty-
     ;;&   #resume (to find ?4 later )
   "24" )
     echo -n twenty-
     ;&   #fallthru
   "4" | [13]4)
     echo -n four 
     ;;&  # resume ( to find teen where needed )
   "14" )
     echo -n teen
  esac
  echo 
done

sample output

4 = four
14 = fourteen
24 = twenty-four
34 = thirty-four

I found a dirty solution:

/bin/bash -c "ulimit -s 65500; exec /usr/local/bin/node --stack-size=65500 /path/to/app.js"

It just increase call stack limit. I think that this is not suitable for production code, but I needed it for script that run only once.

body:before {
    content: " ";
    width: 100%;
    height: 100%;
    position: fixed;
    z-index: -1;
    top: 0;
    left: 0;
    background: rgba(0, 0, 0, 0.5);
}

I'm having a hard time figuring out what exactly you're looking for here, so hope I'm not way off base.

I'm assuming what you mean is that when a keyup event occurs on the input with class "start" you want to get the values of all the inputs in neighbouring <td>s:

    $('.start').keyup(function() {
        var otherInputs = $(this).parents('td').siblings().find('input');

        for(var i = 0; i < otherInputs.length; i++) {
            alert($(otherInputs[i]).val());
        }
        return false;
    });

There are two issues in your code.

1. Use getElementByName instead of getElement**s**ByName
2. use the value in lowercase instead of Value.

I've used most of the times the LIKE option and it works just fine. I just like to share one of my latest experiences where I used INSTR function. Regardless of the reasons that made me consider this options, what's important here is that the use is similar: instr(A, 'text 1') > 0 or instr(A, 'text 2') > 0 Another option could be: (instr(A, 'text 1') + instr(A, 'text 2')) > 0

I'd go with the LIKE '%text1%' OR LIKE '%text2%' option... if not hope this other option helps

1. Normal Class: A Java class

2. Java Beans:

   • All properties private (use getters/setters)
   • A public no-argument constructor
   • Implements Serializable.

3. Pojo: Plain Old Java Object is a Java object not bound by any restriction other than those forced by the Java Language Specification. I.e., a POJO should not have to

   • Extend prespecified classes
   • Implement prespecified interface
   • Contain prespecified annotations

I'd be cautious as dismissing something as a bad idea because it is slow. If it is a part of the code that does not take much time to execute then the slowness is irrelevant. I just used the following code:

for (ic in 1:(dim(centroid)[2]))
{
cluster[[ic]]=matrix(,nrow=2,ncol=0)
}
# code to identify cluster=pindex[ip] to which to add the point
if(pdist[ip]>-1)
{
cluster[[pindex[ip]]]=cbind(cluster[[pindex[ip]]],points[,ip])
}

for a problem that ran in less than 1 second.

If you can make use of equals, then filter the list by using distinct within a stream (see answers above). If you can not or don't want to override the equals method, you can filter the stream in the following way for any property, e.g. for the property Name (the same for the property Id etc.):

Set<String> nameSet = new HashSet<>();
List<Employee> employeesDistinctByName = employees.stream()
            .filter(e -> nameSet.add(e.getName()))
            .collect(Collectors.toList());

nope, none of this will work. What you need is this!!!

Try this:

if (screen.width <= 960) {
  alert('Less than 960');
} else if (screen.width >960) {
  alert('More than 960');
}

Using openCV and numpy it is as easy as this:

import cv2

img = cv2.imread('path/to/img',0)
height, width = img.shape[:2]

All of the answers is true.This is another way. And I like this One

SqlCommand cmd = conn.CreateCommand()

you must notice that strings concat have a sql injection problem. Use the Parameters http://msdn.microsoft.com/en-us/library/system.data.sqlclient.sqlcommand.parameters.aspx

Uploading files is actually possible with AJAX these days. Yes, AJAX, not some crappy AJAX wannabes like swf or java.

This example might help you out: https://webblocks.nl/tests/ajax/file-drag-drop.html

(It also includes the drag/drop interface but that's easily ignored.)

Basically what it comes down to is this:

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

<script>
document.getElementById('files').addEventListener('change', function(e) {
    var file = this.files[0];
    var xhr = new XMLHttpRequest();
    (xhr.upload || xhr).addEventListener('progress', function(e) {
        var done = e.position || e.loaded
        var total = e.totalSize || e.total;
        console.log('xhr progress: ' + Math.round(done/total*100) + '%');
    });
    xhr.addEventListener('load', function(e) {
        console.log('xhr upload complete', e, this.responseText);
    });
    xhr.open('post', '/URL-HERE', true);
    xhr.send(file);
});

So basically what it comes down to is this =)

xhr.send(file);

Where file is typeof Blob: http://www.w3.org/TR/FileAPI/

Another (better IMO) way is to use FormData. This allows you to 1) name a file, like in a form and 2) send other stuff (files too), like in a form.

var fd = new FormData;
fd.append('photo1', file);
fd.append('photo2', file2);
fd.append('other_data', 'foo bar');
xhr.send(fd);

FormData makes the server code cleaner and more backward compatible (since the request now has the exact same format as normal forms).

All of it is not experimental, but very modern. Chrome 8+ and Firefox 4+ know what to do, but I don't know about any others.

This is how I handled the request (1 image per request) in PHP:

if ( isset($_FILES['file']) ) {
    $filename = basename($_FILES['file']['name']);
    $error = true;

    // Only upload if on my home win dev machine
    if ( isset($_SERVER['WINDIR']) ) {
        $path = 'uploads/'.$filename;
        $error = !move_uploaded_file($_FILES['file']['tmp_name'], $path);
    }

    $rsp = array(
        'error' => $error, // Used in JS
        'filename' => $filename,
        'filepath' => '/tests/uploads/' . $filename, // Web accessible
    );
    echo json_encode($rsp);
    exit;
}

Mongoose basically wraps mongodb's api to give you a pseudo relational db api so queries are not going to be exactly like mongodb queries. Mongoose findOne query returns a query object, not a document. You can either use a callback as the solution suggests or as of v4+ findOne returns a thenable so you can use .then or await/async to retrieve the document.

// thenables
Auth.findOne({nick: 'noname'}).then(err, result) {console.log(result)};
Auth.findOne({nick: 'noname'}).then(function (doc) {console.log(doc)});

// To use a full fledge promise you will need to use .exec()
var auth = Auth.findOne({nick: 'noname'}).exec();
auth.then(function (doc) {console.log(doc)});

// async/await
async function auth() {
  const doc = await Auth.findOne({nick: 'noname'}).exec();
  return doc;
}
auth();

See the docs if you would like to use a third party promise library.

Well, your whole code can be limited to:

foreach $line (@lines){
        $strings{$1}++ if $line =~ m|my regex|;
}

If the value is not there, ++ operator will assume it to be 0 (and then increment to 1). If it is already there - it will simply be incremented.

I would prefer using the most easiest method.

Right click on the Wamp icon and go to

Tools > Use a port other than 8080 >

Set a different port, lets say 8081 and that's it. Problem resolved.

You are most welcome.

I got pretty close to what I wanted by doing something like this

cat my.json | jq '.my.prefix[] | .primary_key + ":", (.sub.prefix[] | "    - " + .sub_key)' | tr -d '"' 

The output of which is close enough to yaml for me to usually import it into other tools without much problem. (I am still looking for a way to basicallt export a subset of the input json)

label is an inline element so its width is equal to the width of the text it contains. The browser is actually displaying the label with text-align:center but since the label is only as wide as the text you don't notice.

The best thing to do is to apply a specific width to the label that is greater than the width of the content - this will give you the results you want.

Using itertools.chain:

import itertools
from collections import Iterable

def list_flatten(lst):
    flat_lst = []
    for item in itertools.chain(lst):
        if isinstance(item, Iterable):
            item = list_flatten(item)
            flat_lst.extend(item)
        else:
            flat_lst.append(item)
    return flat_lst

Or without chaining:

def flatten(q, final):
    if not q:
        return
    if isinstance(q, list):
        if not isinstance(q[0], list):
            final.append(q[0])
        else:
            flatten(q[0], final)
        flatten(q[1:], final)
    else:
        final.append(q)
